ABSTRACT
Objective To construct a human health literacy indicator system for prevention of parasitic diseases based on Delphi method. Methods Based on literature reviews and expert interviews, a questionnaire was designed and a two-round Delphi consultation was performed. A human health literacy indicator system for prevention of parasitic diseases was constructed according to the deletion criteria and experts’ advice. Results A total of 14 experts completed the two-round consultation. The second-round authority coefficients were 0.91 to 0.96 for the first-level indicators, 0.87 to 0.97 for the second-level indicators and 0.86 to 0.97 for the third-level indicators. A human health literacy indicator system for prevention of parasitic diseases was constructed with the main framework of basic knowledge and awareness, healthy behaviors, and healthy skills, which contained 3 first-level indicators, 12 second-level indicators and 48 third-level indicators. Among the three first-level indicators, basic knowledge and awareness had the highest weighting coefficient (0.336 5), followed by healthy behaviors (0.334 9), and healthy skills had the lowest weighting coefficient (0.328 6). The three secondary-level indicators with the highest combined weights included awareness of the epidemic status (0.088 2), awareness of the resource of infection (0.085 8) and basic awareness of parasitic diseases (0.085 5). Conclusion A human health literacy indicator system for prevention of parasitic diseases is preliminarily constructed, which provides insights into the development of health literacy evaluation tools for prevention of parasitic diseases in the new era.
ABSTRACT
Objective:To investigate macular microvascular abnormalities in eyes with subfoveal fibrotic nodules secondary to Coats' disease.Methods:A cross-sectional study. From January 1, 2018 to July 30, 2021, 45 eyes of 45 patients diagnosed with Coats' disease with or without subfoveal fibrotic nodules in Eye and ENT Hospital, Shanghai Medical College of Fudan University were included in this study. There were 40 eyes in 40 males and 5 eyes in 5 females. All were under 21 years old. According to the presence or absence of subfoveal fiber nodules, the patients were divided into fibrotic group (26 cases, 26 eyes) and non-fibrotic group (19 cases, 19 eyes). Optical coherence tomography angiography was used to scan 3 mm×3 mm or 6 mm×6 mm macular area of both eyes. The software of the device automatically processed the images. The presence of FAZ edge anastomotic vascular arch ring breakage and abnormal microvascular branch (AMB) in the foveal avascular zone (FAZ) were observed.Results:In 26 eyes of fibrosis group, AMB originating from the parafoveal retinal capillary network was observed, which grew into and destroyed the integrity of the vascular arch ring at the edge of FAZ. AMB was crisscrossing and winding, and its curvature expands. B-scan images showed the blood flow signal in the subfoveal fiber nodule, and the blood flow signal traversed between the inner retina and the fiber nodule in 23 eyes (88.46%, 23/26). In the non-fibrosis group, all the vascular abnormalities were characterized by capillary dilation and defect, and no breakage of FAZ anastomotic vascular arch ring or AMB was observed.Conclusions:In Coats' disease with subfoveal fiber nodules, staggered and dilated AMBs emerge from the parafoveal vascular network, grow into and destroy the integrity of the vascular arch ring at the edge of FAZ, and grow down longitudinally into the fiber nodules.
ABSTRACT
Objective:To investigate the efficacy and safety of traditional laser photocoagulation, laser combined with intravitreal injection of anti-vascular endothelial factor (anti-VEGF) drugs and intravitreal injection of anti-VEGF drugs alone in Coats disease.Methods:The patients diagnosed as Coats disease stage 2B-3A2 in Department of Ophthalmology, Eye and ENT Hospital of Shanghai Medical College of Fudan University from December 2016 to November 2019 were included in this study. Patients were divided into three groups, including laser group, combined group and drug group, according to the different treatment. In the laser group, the initial treatment was traditional laser photocoagulation alone. In the drug group, the anti-VEGF drug was injected into vitreous once a month for three months. The initial treatment of the eyes in the combined group was laser combined with intravitreal injection of anti-VEGF drugs, or laser treatment within 1 week after anti-VEGF drug treatment. The follow-up time was more than 6 months, and best-corrected visual acuity (BCVA), ultra-wide-angle fundus photography, and fluorescein fundus angiography were performed during follow-up. The treatment efficiency, subretinal fluid (SRF), macular edema, BCVA and complications were compared among the three groups.Results:Among 60 patients (60 eyes), there were 55 males (55 eyes) and 5 females (5 eyes), with the mean age of 17.1±2.0 years. Among 60 eyes, there were 26 eyes in 2B stage, 23 eyes in 3A1 stage, and 11 eyes in 3A2 stage. Twenty patients (20 eyes) was in the laser group, combined group and drug group, respectively. After the initial treatment of all eyes in the drug group, the abnormal blood vessels did not regress significantly; the absorption and increase of SRF were 4 (20.0%, 4/20) and 5 (25.0%, 5/20) eyes, respectively. Supplementary laser therapy was given to 16 eyes, and vitrectomy (PPV) was given to 4 eyes. Among the 16 eyes treated by laser, 10 eyes were effective (50.0%, 10/20); vitreous hemorrhage, fibrous membrane hyperplasia, and complicated cataract occurred in 1, 1, and 2 eyes during the treatment, respectively, and PPV was given again in all eyes. Recurrent and persistent macular edema occurred in 4 and 1 eyes, respectively. Among the eyes in the combined group, treatment were effective in 11 eyes (55.0%, 11/20); 5, 2, and 2 eyes had SRF, fibrous membrane hyperplasia, and complicated cataract during the treatment, and PPV was given again; the edema was repeated and persisted in 1 eye, respectively. Among the affected eyes in the laser group, 15 eyes (75.0%, 15/20) were treated effectively; 2, 2, and 1 eyes developed a large number of vitreous hemorrhage, fibrous membrane hyperplasia, and complicated cataract during the treatment, and PPV was given again.Conclusions:Anti-VEGF drugs alone are ineffective in the treatment of Coats disease, and ablation of other abnormal blood vessels is needed. In the treatment of Coats disease, anti-VEGF drugs can not only promote the absorption of SRF, but also may lead to its increase, and the application should be cautious.
ABSTRACT
Objective:To analyze the consistency and correlation of indirect calorimetry (IC) and Harris-Benedict estimation method (H-B) in measuring energy consumption in patients with severe acute pancreatitis (SAP), as well as the characteristics of energy metabolism at resting state of SAP patients with different etiologies, and so as to guide the formulation of clinical energy nutrition support program.Methods:From February 1 to December 31, 2019, 61 SAP patients admitted into the intensive care unit of the First Affiliated Hospital of Nanchang University were enrolled. Collected relevant data of patients, such as the etiology of SAP, whether mechanical ventilation was needed, as well as the metabolic status. All SAP patients accepted IC test on the first day after admission to intensive care unit. According to the energy consumption measured by IC (hereinafter referred to as IC value) and the energy consumption measured by H-B (hereinafter referred to as H-B value), SAP patients were determined to be in high, normal or low metabolic state. Bland-Altman method and Pearson linear regression were used to analyze the consistency and correlation of the two methods in measuring energy consumption, and the linear equation was fitted. Paired t test was used for statistical analysis. Results:Among the 61 SAP patients, 13 cases were biliary SAP, 30 cases were hyperlipidemic SAP, 6 cases were alcoholic SAP, and 12 cases were SAP of other causes or unknown causes. Nineteen cases needed mechanical ventilation and 42 cases did not need mechanical ventilation. There were 70.5% (43/61) of SAP patients in high metabolic state, 13.1%(8/61) of SAP patients in normal metabolic state, and 16.4% (10/61) of SAP patients in low metabolic state. The IC value in 61 SAP patients was higher than H-B value((8 604.7±367.8) kJ/d vs. (6 491.2±133.7) kJ/d), and the difference was statistically significant ( t=5.95, P<0.001). The IC value in patients with hyperlipidemic, alcoholic and biliary SAP was (8 815.2±537.9), (7 631.2±890.5), and (8 108.0±933.1) kJ/d, respectively, and the H-B value was (6 869.6±204.5), (5 916.8±153.7), and (5 974.2±200.9) kJ/d, respectively. The IC value in patients with biliary or hyperlipidemic SAP were higher than H-B value, and the differences were statistically significant( t=2.29 and 3.38, both P<0.05). The IC value and H-B value in SAP patients with mechanical ventilation and without mechanical ventilation were (10 485.0±741.1) and (6 462.6±222.8) kJ/d, (6 595.1±364.7) and (6 503.2±166.7) kJ/d, respectively. The IC value in SAP patients with mechanical ventilation was higher than H-B value and the IC value in SAP patients without mechanical ventilation, and the differences were statistically significant ( t=4.71 and 5.20, both P<0.001). The consistency analyzed by Bland-Altman method showed that the two methods had obvious biases, and the average bias value was 92.2 kJ/d. The result of Pearson linear regression analysis indicated that there was a linear relationship between two methods ( r=0.44, P<0.001). The linear equation fitted by the univariate regression was Y=1.240 6 X+ 154.42, in which X was the H-B value and Y was the IC value. Conclusions:SAP patients are mostly in a hypermetabolic state in the early stages of the disease. The IC value is higher than H-B value, and it is recommended to use IC to measure energy consumption in SAP patients.
ABSTRACT
Objective:To explore the value and feasibility of abbreviated comprehensive geriatric assessment(aCGA)grading in elderly patients with breast cancer.Methods:From June 2019 to January 2020, elderly patients with breast cancer aged 65 years and above were enrolled.Eastern Cooperative Oncology Group(ECOG)score and aCGA classification were performed respectively.Clinical characteristics, score distribution and differences between the two assessment methods were compared and analyzed.Results:A total of 61 cases of breast cancer patients aged 65 years and above were included in our study.According to the assessment of aCGA, grade A accounted for 65.5%(40/61), grade B accounted for 27.9%(17/61), and grade C accounted for 6.6%(4/61), among which 82.0%(50/61 cases)of the patients had complications.And the most common complications were hypertension, cardiovascular disease and diabetes.Among the 50 patients with ECOG score 0-1, 74.0%(37/50)were aCGA grade A, and 26.0%(13/50)were aCGA grade B.Conclusions:According to the aCGA grading, about two thirds of breast cancer patients over 65 years old are assessed as grade A, which indicates that they might have better tolerance during the treatment.However, among the patients with 0-1 score according to the ECOG score, some patients still have a slightly worse grade(aCGA grade B, which shows slightly worse health condition), suggesting that the refinement degree of ECOG score may be insufficient, and the health damage of some patients may be underestimated.
ABSTRACT
Abivertinib, a third-generation tyrosine kinase inhibitor, is originally designed to target epidermal growth factor receptor (EGFR)-activating mutations. Previous studies have shown that abivertinib has promising antitumor activity and a well-tolerated safety profile in patients with non-small-cell lung cancer. However, abivertinib also exhibited high inhibitory activity against Bruton's tyrosine kinase and Janus kinase 3. Given that these kinases play some roles in the progression of megakaryopoiesis, we speculate that abivertinib can affect megakaryocyte (MK) differentiation and platelet biogenesis. We treated cord blood CD34+ hematopoietic stem cells, Meg-01 cells, and C57BL/6 mice with abivertinib and observed megakaryopoiesis to determine the biological effect of abivertinib on MK differentiation and platelet biogenesis. Our in vitro results showed that abivertinib impaired the CFU-MK formation, proliferation of CD34+ HSC-derived MK progenitor cells, and differentiation and functions of MKs and inhibited Meg-01-derived MK differentiation. These results suggested that megakaryopoiesis was inhibited by abivertinib. We also demonstrated in vivo that abivertinib decreased the number of MKs in bone marrow and platelet counts in mice, which suggested that thrombopoiesis was also inhibited. Thus, these preclinical data collectively suggested that abivertinib could inhibit MK differentiation and platelet biogenesis and might be an agent for thrombocythemia.

LIN28 is an RNA binding protein with important roles in early embryo development, stem cell differentiation/reprogramming, tumorigenesis and metabolism. Previous studies have focused mainly on its role in the cytosol where it interacts with Let-7 microRNA precursors or mRNAs, and few have addressed LIN28's role within the nucleus. Here, we show that LIN28 displays dynamic temporal and spatial expression during murine embryo development. Maternal LIN28 expression drops upon exit from the 2-cell stage, and zygotic LIN28 protein is induced at the forming nucleolus during 4-cell to blastocyst stage development, to become dominantly expressed in the cytosol after implantation. In cultured pluripotent stem cells (PSCs), loss of LIN28 led to nucleolar stress and activation of a 2-cell/4-cell-like transcriptional program characterized by the expression of endogenous retrovirus genes. Mechanistically, LIN28 binds to small nucleolar RNAs and rRNA to maintain nucleolar integrity, and its loss leads to nucleolar phase separation defects, ribosomal stress and activation of P53 which in turn binds to and activates 2C transcription factor Dux. LIN28 also resides in a complex containing the nucleolar factor Nucleolin (NCL) and the transcriptional repressor TRIM28, and LIN28 loss leads to reduced occupancy of the NCL/TRIM28 complex on the Dux and rDNA loci, and thus de-repressed Dux and reduced rRNA expression. Lin28 knockout cells with nucleolar stress are more likely to assume a slowly cycling, translationally inert and anabolically inactive state, which is a part of previously unappreciated 2C-like transcriptional program. These findings elucidate novel roles for nucleolar LIN28 in PSCs, and a new mechanism linking 2C program and nucleolar functions in PSCs and early embryo development.

ABSTRACT
Objective: To analyze the effects of transient receptor potential vanilloid type 4 (TRPV4) activation on the function and endothelial-to-mesenchymal transition (EndMT) of human umbilical vein endothelial cells (HUVECs), as well as to explore the effects of TRPV4 activation on blood perfusion and survival of rat perforator flap and the mechanism. Methods: The experimental research methods were used. The 3rd to 6th passages of HUVECs were used for experiments and divided into 0.5 μmol/L 4α-phorbol 12, 13-didecanoate (4αPDD) group, 1.0 μmol/L 4αPDD group, 3.0 μmol/L 4αPDD group, 10.0 μmol/L 4αPDD group, and phosphate buffer solution (PBS) group, which were cultivated in corresponding final molarity of 4αPDD and PBS, respectively. The cell proliferation activity at 6 and 12 h of culture was detected using cell counting kit-8 (CCK-8). Another batch of cells was acquired and divided into PBS group, 1 μmol/L 4αPDD group, and 3 μmol/L 4αPDD group, which were treated similarly as described before and then detected for cell proliferation activity at 6, 12, 24, and 48 h of culture. The residual scratch area of cells at post scratch hour (PSH) 12, 24, and 48 was detected by scratch test, and the percentage of the residual scratch area was calculated. The number of migrated cells at 24 and 48 h of culture was detected by Transwell experiment. The tube-formation assay was used to measure the number of tubular structures at 4 and 8 h of culture. The protein expressions of E-cadherin, N-cadherin, Slug, and Snail at 24 h of culture were detected by Western blotting. All the sample numbers in each group at each time point in vitro experiments were 3. A total of 36 male Sprague-Dawley rats aged 8 to 10 weeks were divided into delayed flap group, 4αPDD group, and normal saline group according to the random number table, with 12 rats in each group, and iliolumbar artery perforator flap models on the back were constructed. The flap surgical delay procedure was only performed in the rats in delayed flap group one week before the flap transfer surgery. Neither rats in 4αPDD group nor normal saline group had flap surgical delay; instead, they were intraperitoneally injected with 4αPDD and an equivalent mass of normal saline, respectively, at 10 min before, 24 h after, and 48 h after the surgery. The general state of flap was observed on post surgery day (PSD) 0 (immediately), 1, 4, and 7. The flap survival rates were assessed on PSD 7. The flap blood perfusion was detected by laser speckle contrast imaging technique on PSD 1, 4, and 7. The microvascular density in the flap's choke vessel zone was detected by immunohistochemical staining. All the sample numbers in each group at each time point in vivo experiments were 12. Data were statistically analyzed with analysis of variance for factorial design, analysis of variance for repeated measurement, one-way analysis of variance, least significant difference t test, and Bonferroni correction. Results: At 6 and 12 h of culture, there were no statistically significant differences in cell proliferation activity in the overall comparison among PBS group, 0.5 μmol/L 4αPDD group, 1.0 μmol/L 4αPDD group, 3.0 μmol/L 4αPDD group, and 10.0 μmol/L 4αPDD group (P>0.05). At 6, 12, 24, and 48 h of culture, there were no statistically significant differences in cell proliferation activity in the overall comparison among PBS group, 1 μmol/L 4αPDD group, and 3 μmol/L 4αPDD group (P>0.05). At PSH 12, the percentages of the residual scratch area of cells in 1 μmol/L 4αPDD group and 3 μmol/L 4αPDD group were close to that in PBS group (P>0.05). At PSH 24 and 48, compared with those in PBS group, the percentages of the residual scratch area of cells in 3 μmol/L 4αPDD group were significantly decreased (with t values of 2.83 and 2.79, respectively, P<0.05), while the percentages of the residual scratch area of cells in 1 μmol/L 4αPDD group showed no significant differences (P>0.05). At 24 h of culture, the number of migrated cells in 1 μmol/L 4αPDD group and 3 μmol/L 4αPDD group were close to that in PBS group (P>0.05). At 48 h of culture, the number of migrated cells in 1 μmol/L 4αPDD group and 3 μmol/L 4αPDD groups were significantly greater than that in PBS group (with t values of 6.20 and 9.59, respectively, P<0.01). At 4 h of culture, the numbers of tubular structures of cells in 1 μmol/L 4αPDD group and 3 μmol/L 4αPDD group were significantly greater than that in PBS group (with t values of 4.68 and 4.95, respectively, P<0.05 or <0.01). At 8 h of culture, the numbers of tubular structures of cells in 1 μmol/L 4αPDD and 3 μmol/L 4αPDD groups were similar to that in PBS group (P>0.05). At 24 h of culture, compared with those in PBS group, the protein expression level of E-cadherin of cells in 3 μmol/L 4αPDD group was significantly decreased (t=5.13, P<0.01), whereas there was no statistically significant difference in the protein expression level of E-cadherin of cells in 1 μmol/L 4αPDD group (P>0.05); the protein expression level of N-cadherin of cells in 3 μmol/L 4αPDD group was significantly increased (t=4.93, P<0.01), whereas there was no statistically significant difference in the protein expression level of N-cadherin of cells in 1 μmol/L 4αPDD group (P>0.05); the protein expression levels of Slug of cells in 1 μmol/L 4αPDD group and 3 μmol/L 4αPDD group were significantly increased (with t values of 3.85 and 6.52, respectively, P<0.05 or P<0.01); and the protein expression level of Snail of cells in 3 μmol/L 4αPDD group was significantly increased (t=4.08, P<0.05), whereas there was no statistically significant difference in the protein expression level of Snail of cells in 1 μmol/L 4αPDD group (P>0.05). There were no statistically significant differences in the protein expression levels of E-cadherin, N-cadherin, Slug, or Snail of cells between 1 μmol/L 4αPDD group and 3 μmol/L 4αPDD group (P>0.05). The general condition of flaps of rats in the three groups was good on PSD 0. On PSD 1, the flaps of rats in the three groups were basically similar, with bruising and swelling at the distal end. On PSD 4, the swelling of flaps of rats in the three groups subsided, and the distal end turned dark brown and necrosis occurred, with the area of necrosis in flaps of rats in normal saline group being larger than the areas in 4αPDD group and delayed flap group. On PSD 7, the necrotic areas of flaps of rats in the 3 groups were fairly stable, with the area of necrosis at the distal end of flap of rats in delayed flap group being the smallest. On PSD 7, the flap survival rates of rats in 4αPDD group ((80±13)%) and delayed flap group ((87±9)%) were similar (P>0.05), and both were significantly higher than (70±11)% in normal saline group (with t values of 2.24 and 3.65, respectively, P<0.05 or P<0.01). On PSD 1, the overall blood perfusion signals of rats in the 3 groups were basically the same, and the blood perfusion signals in the choke vessel zone were relatively strong, with a certain degree of underperfusion at the distal end. On PSD 4, the boundary between the surviving and necrotic areas of flaps of rats in the 3 groups became evident, and the blood perfusion signals in the choke vessel zone were improved, with the normal saline group's distal hypoperfused area of flap being larger than the areas in delayed flap group and 4αPDD group. On PSD 7, the blood perfusion signals of overall flap of rats had generally stabilized in the 3 groups, with the intensity of blood perfusion signal in the choke vessel zone and overall flap of rats in delayed flap group and 4αPDD group being significantly greater than that in normal saline group. On PSD 7, the microvascular density in the choke vessel zone of flap of rats in 4αPDD group and delayed flap group were similar (P>0.05), and both were significantly higher than that in normal saline group (with t values of 4.11 and 5.38, respectively, P<0.01). Conclusions: After activation, TRPV4 may promote the migration and tubular formation of human vascular endothelial cells via the EndMT pathway, leading to the enhanced blood perfusion of perforator flap and microvascular density in the choke vessel zone, and therefore increase the flap survival rate.

Objective: To summarize the clinical experience of expanded internal mammary artery perforator (IMAP) flap combined with vascular supercharge in reconstruction of faciocervical scar. Methods: The retrospective observational study was conducted. From September 2012 to May 2021, 23 patients with postburn or posttraumatic faciocervical scars who met the inclusion criteria were admitted to Shanghai Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine, including 18 males and 5 females, aged from 11 to 58 years, all of whom were reconstructed with expanded IMAP flaps. At the first stage, one or two skin and soft tissue expander (s) with appropriate rated capacity were implanted in the anterior chest area according to the location and size of the scars. The IMAP, thoracic branch of supraclavicular artery, and lateral thoracic artery were preserved during the operation. The skin and soft tissue expanders were inflated with normal saline after the operation. The flaps were transferred during the second stage. The dominant IMAP was determined preoperatively using color Doppler ultrasound (CDU) blood flow detector. The faciocervical scars were removed, forming wounds with areas of 9 cm×7 cm-28 cm×12 cm, and the perforators of superficial temporal artery and vein or facial artery and vein were preserved during the operation. The flaps were designed according to the area and size of the wounds after scar resection with the dominant IMAP as the pedicle. Single-pedicle IMAP flaps were used to repair small and medium-sized wounds. For larger defects, the blood perfusion areas of vessels in the anterior chest were evaluated by indocyanine green angiography (ICGA). In situations where the IMAP was insufficient to nourish the entire flap, double-pedicle flaps were designed by using the thoracic branch of supraclavicular artery or lateral thoracic artery for supercharging. Pedicled or free flap transfer was selected according to the distance between the donor areas and recipient areas. After transplantation of flaps, ICGA was conducted again to evaluate blood perfusion of the flaps. The donor sites of flaps were all closed by suturing directly. Statistics were recorded, including the number, rated capacity, normal saline injection volume, and expansion period of skin and soft tissue expanders, the location of the dominant IMAP, the total number of the flaps used, the number of flaps with different types of vascular pedicles, the flap area, the flap survival after the second stage surgery, the occurrence of common complications in the donor and recipient areas, and the condition of follow-up. Results: Totally 25 skin and soft tissue expanders were used in this group of patients, with rated capacity of 200-500 mL, normal saline injection volume of 855-2 055 mL, and expansion period of 4-16 months. The dominant IMAP was detected in the second intercostal space (20 sides) or the third intercostal space (5 sides) before surgery. A total of 25 expanded flaps were excised, including 2 pedicled IMAP flaps, 11 free IMAP flaps, 4 pedicled thoracic branch of supraclavicular artery+free IMAP flaps, and 8 free IMAP+lateral thoracic artery flaps, with flap areas of 10 cm×8 cm-30 cm×14 cm. After the second stage surgery, tip necrosis of flaps in three patients occurred, which healed after routine dressing changes; one patient developed arterial embolism and local torsion on the vascular pedicle at the anastomosis of IMAP and facial artery, and the blood supply recovered after thrombectomy and vascular re-anastomosis. Fourteen patients underwent flap thinning surgery in 1 month to 6 months after the second stage surgery. The follow-up for 4 months to 9 years showed that all patients had improved appearances of flaps and functions of face and neck and linear scar in the donor sites of flaps, and one female patient had obvious nipple displacement and bilateral breast asymmetry. Conclusions: The expanded IMAP flap is matched in color and texture with that of the face and neck, and its incision causes little damage to the chest donor sites. When combined with vascular supercharge, a double-pedicle flap can be designed flexibly to further enhance the blood supply and expand the flap incision area, which is a good choice for reconstruction of large faciocervical scar.

Objective:To investigate the clinical efficacy of conservative and surgical treatment of testicular appendage torsion in children and to summarize the experience.Methods:The clinical data of 106 children with testicular appendage torsion admitted in Tengzhou Central People's Hospital Affiliated to Xuzhou Medical University from January 2012 to December 2018 were retrospectively analyzed. According to different therapeutic methods, all the children were divided into conservative group (25 cases) and surgical group (81 cases). The clinical efficacy was compared between the two groups.Results:106 children with testicular appendage torsion were cured. The hospitalization time [(5.61±1.04)d vs (11.32±1.89)d], pain relief time [(9.11±2.56)d vs (68.5±19.87)d], disappearance time of scrotal edema [(5.11±1.08)d vs (10.56±1.50)d] and the utility time of antibiotic [(4.89±1.32)d vs (7.06±1.26)d] in the surgical group were shorter than those in the conservative group, with statistically significant difference(all P<0.05). After 6 months of follow-up, there were no cases of recurrence and discomfort in the two groups. Conclusions:Children with testicular appendage torsion should be actively treated with surgery, which can not only significantly shorten the course of disease, but also reduce the incidence of complications and missed diagnosis. For children who with testicular appendage torsion, surgeries should be performed actively. It can significantly shorten the duration of symptoms, but also reduce the occurrence of complication and the occurrence probability of misdiagnosis.

ABSTRACT
OBJECTIVES@#To study the clinical value of attention time combined with behavior scale in the screening of attention deficit hyperactivity disorder (ADHD) in preschool children.@*METHODS@#A total of 200 preschool children with ADHD diagnosed in Fujian Maternal and Child Health Hospital from February 2019 to March 2020 were enrolled as the ADHD group. A total of 200 children who underwent physical examination in the hospital or kindergartens during the same period were enrolled as the control group. Attention time was recorded. Chinese Version of Swanson Nolan and Pelham, Version IV Scale-Parent Form (SNAP-IV) scale was used to evaluate symptoms. With clinical diagnosis as the gold standard, the decision tree analysis was used to evaluate the clinical value of attention time combined with behavior scale in the screening of ADHD.@*RESULTS@#Compared with the control group, the ADHD group had significantly higher scores of SNAP-IV items 1, 4, 7, 8, 10, 11, 14, 15, 16, 18, 20, 21, and 22 (P<0.05) and a significantly shorter attention time (P<0.05). The variables with statistically significant differences between the two groups in univariate analysis were used as independent variables to establish a decision tree model. The accuracy of the model in predicting ADHD was 81%, that in predicting non-ADHD was 69%, and the overall accuracy was 75%, with an area under the ROC curve of 0.816 (95% CI: 0.774-0.857, P<0.001).@*CONCLUSIONS@#The decision tree model for screening ADHD in preschool children based on attention time and assessment results of behavior scale has a high accuracy and can be used for rapid screening of ADHD among children in clinical practice.

The choice of friction interface has always been a controversial topic in hip arthroplasty. Although the metal-on-metal (MoM) interface has gradually faded out of our vision, its revision is a clinical difficulty. Adverse reactions to metal debris (ARMD) is the most common indication for MoM hip arthroplasty revision, and the clinical results of hip arthroplasty due to ARMD are not satisfactory. At present, the indications and suggestions for revision of ARMD are not uniform. In this article, the clinical diagnosis, indications of revision, risk factors of prognosis, intraoperative suggestions and reasons for revision of ARMD were summarized. This article briefly introduces the diagnosis and treatment strategies and precautions of hip arthroplasty due to ARMD, in order to provide reference for such patients in clinical practice.

OBJECTIVE@#To investigate the morphological, histological and ultrastructural changes of acute closed rupture of Achilles tendon, in order to clarify the pathological basis of the injury and to explore the significance.@*METHODS@#From January 2015 to January 2019, 35 patients with acute Achilles tendon rupture who underwent the minimally invasive Achilles tendon suture technique were retrospectively analyzed. Among these patients, 12 cases in acute open Achilles tendon rupture group included 10 males and 2 females, with an average age of (35.1±9.7) years old ranging from 19 to 50, and the time from injury to operation was 2 to 8 hours with an average of(5.6±1.8);23 cases in acute closed Achilles tendon rupture group included 21 males and 2 females, with an average age of (35.5±6.6) years old ranging from 18 to 50, and the time from injury to operation was 3 to 15 hours with an average of (7.5±3.1). The gross appearance and imaging findings of the broken end of Achilles tendon tissue in the two groups were compared by naked eye observation and foot and ankle MRI at 4 to 6 hours before operation. HE staining, scanning and fluoroscopic electron microscopy, immunohistochemistry(Sirius red staining) were performed on the intraoperative Achilles tendon tissue specimens at 1 to 2 days after operation, the collagen fiber degeneration and local fat infiltration, collagen fiber shape, cell morphology and function, and the distribution of typeⅠand type Ⅲ collagen fibers in Achilles tendon were compared between the two groups.@*RESULTS@#Compared with the acute open Achilles tendon rupture group, the acute closed Achilles tendon rupture group had poor elasticity, hard texture, moderate edema, irregular shape of Achilles tendon broken end, horsetail shape, and more calcification around the broken end. HE staining results:the collagen fibers in the Achilles tendon of the acute open Achilles tendon rupture group were arranged irregularly, with hyaline degeneration and fat infiltration;The results of electron microscopy showed that collagen arranged disorderly and fibroblasts atrophied in the acute closed Achilles tendon rupture group. Immunohistochemical(Sirius staining) results:the proportion of collagenⅠin the acute open Achilles tendon rupture group and the acute closed Achilles tendon rupture group was(91.12±4.34)% and(54.71±17.78)% respectively, and the proportion of collagen Ⅲ was (8.88±4.34)% and (45.29±17.78)% respectively. The content of collagenⅠin the acute closed Achilles tendon rupture group was lower than that in the acute open Achilles tendon rupture group, and the content of collagen Ⅲ in the acute closed Achilles tendon rupture group was higher than that in the acute open Achilles tendon rupture group(P<0.05).@*CONCLUSION@#The morphology, histology and ultrastructure of the acute closed ruptured Achilles tendon are significantly altered compared with the normal Achilles tendon. The original fine and orderly spatial structure cannot be maintained, part of collagen Ⅰ is replaced by collagen Ⅲ, and the toughness and strength of the tendon tissue decreased, which may be the feature of degeneration of the Achilles tendon and an important pathological basis for closed Achilles tendon rupture.

@#Objective To analyze the influencing factors of post-operative delirium (POD) in middle-aged and elderly patients in intensive care unit (ICU) and construct risk prediction model for it.Methods A total of 112 middle-aged and elderly postoperative patients in the ICU of Lu'an Hospital of Anhui Medical University from January, 2018 to February, 2021 were selected. On the second day after the operation, they were transferred to ICU, and assessed with the Confusion AssessmentMethod for Intensive Care Unit (CAM-ICU). The patients were divided into delirium group (n = 52) and non-delirium group (n = 60) according to assessment. Univariate analysis was used to compare the differences in clinical data between the two groups, and multivariate Logistic regression analysis was used to screen the independent influencing factors to construct risk prediction model. Receiver operating characteristic (ROC) curve was used to evaluate prediction performance. Results Multivariate logistic regression analysis showed Acute Physiology and Chronic Health Evaluation II score (APACHE II score) (OR = 1.424, 95%CI 1.204 to 1.685, P < 0.001), ICU sleep quality score (OR = 1.432, 95%CI 1.159 to 1.770, P < 0.001), and postoperative oxygenation index ≤ 300 (OR = 4.485, 95%CI 1.644 to 12.240, P = 0.001) were independent influencing factors of postoperative delirium in ICU. The prediction model was: logit(P) = -11.381+0.354X1 (APACHE II score, cut-off value 16)+0.359X2 (ICU sleep quality score, cut-off value 13)+1.501X3 (postoperative oxygenation index ≤ 300), with the sensitivity and specificity of 79.2% and 79.7% respectively. The area under the ROC curve was 0.866 (95%CI 0.801 to 0.930), more than those of the factors alone (P < 0.05). Conclusion The prediction model based on Logistic regression can predict the occurrence of postoperative delirium in middle-aged and elderly patients in ICU.
ABSTRACT
ObjectiveTo explore the mechanism of Fangji Fulingtang in the treatment of acute kidney injury (AKI) induced by ischemia-reperfusion based on network pharmacology and experimental verification. MethodActive components of Fangji Fulingtang were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and previous report and targets of these components were predicted by SwissTargetPrediction. The targets of AKI were searched from GeneCards, Online Mendelian Inheritance in Man (OMIM), the database of gene-disease associations (DisGeNET), and Therapeutic Target Database (TTD). Protein-protein interaction (PPI) network was constructed by STRING. Metascape was used for Gene Ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of core targets. Cytoscape was employed to construct the "medicinal-active component-target-disease" network and “active component-target-pathway” network. AutoDock was applied for molecular docking. Finally, animal experiment was carried out to validate the mechanism of Fangji Fulingtang in treatment of AKI. ResultA total of 137 active components and 858 targets of Fangji Fulingtang, 1 294 targets of AKI, and 267 targets of Fangji Fulingtang in the treatment of AKI were screened out. Phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), proto-oncogene tyrosine protein kinase (SRC), protein kinase B1 (Akt1), and mitogen-activated protein kinase 3 (MAPK3) were the key anti-AKI targets of Fangji Fulingtang, which were involved in 1 609 GO terms, particularly cell response to lipids, membrane rafts, and protein kinase activity, and 140 KEGG pathways such as PI3K/Akt signaling pathway, chemokine signaling pathway, and Toll-like receptor signaling pathway. Molecular docking showed that the core active components had strong binding affinity to the key targets. The hematoxylin and eosin (HE) staining results indicated that Fangji Fulingtang can significantly improve the pathological state and the serological results suggested that the levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were significantly reduced. ConclusionThis study clarified the mechanism of Fangji Fulingtang in the treatment of AKI and found that Fangji Fulingtang had the multi-component, multi-target, and multi-pathway characteristics in the treatment of AKI. The result lays a foundation for further study of its specific mechanism.
ABSTRACT
Objective:To investigate the clinical characteristics, treatment and prognosis of primary vitreoretinal lymphoma (PVRL) diagnosed and treated in our hospital during the past 10 years.Methods:A retrospective clinical study. From 2011 to 2021, 126 eyes of 67 patients with PVRL who were diagnosed and treated in Department of Ophthalmology, Eye-ENT Hospital, Fudan University were included in the study. Among them, there were 23 males (34.3%, 23/67) and 44 females (65.7%, 44/67); the average age was 57.1 years. There were 59 cases with both eyes (88.1%, 59/67) and 8 cases with one eye (11.9%, 8/67). At the initial eye diagnosis, 22 cases had a clear history of primary central nervous system lymphoma (PCNSL); 5 cases were found to have intracranial lesions by head imaging examination; 40 cases had no central nervous system involvement. Twenty cases were treated with glucocorticoids due to misdiagnosed uveitis. All patients received intravitreal injection of methotrexate (IVM) treatment. The treatment regimen was twice a week in the induction period for 2 weeks, once a week in the consolidation period for 1 month, and once a month in the maintenance period. Patients with PCNSL or both eyes received concurrent systemic chemotherapy (chemotherapy), and some in combination with radiation therapy to the brain (radiotherapy). The mean follow-up time was 39.3 months. The clinical manifestations, treatment and prognosis of the patients were retrospectively analyzed. The visual acuity before and after treatment was compared by t test. Results:Among the 22 cases with a clear history of PCNSL at the initial eye diagnosis, the average time from intracranial diagnosis to eye diagnosis was 22.9 months. Among the 40 cases without central nervous system involvement at first, 14 cases (20.9%, 14/67) developed central nervous system lesions during follow-up period. The mean time from ocular diagnosis to intracranial diagnosis was 9.9 months. Among the 126 eyes, 42 eyes (33.3%, 42/126) had anterior segment inflammation. vitreous inflammation type, retinal type, and vitreous retinal type were 58 (46.0%, 58/126), 7 (5.6%, 7/126), and 61 (48.4%, 61/126) eyes, and 9 of them (7.1%, 9/126) had optic nerve involvement at the same time. Patients received an average of 12 IVM treatments. IVM combined with systemic chemotherapy in 59 cases (88.1%, 59/67), of which 16 cases were combined with brain radiotherapy. All patients achieved complete remission after completing the treatment cycle (100.0%, 67/67). After treatment, 21 eyes (16.7%, 21/126) had ocular recurrence; 22 (32.8%, 22/67) had intracranial recurrence; 8 cases (11.9%, 8/67) died. The mean progression-free survival of patients was 23.7 months; the mean survival time was 43.6 months; the 5-year overall survival rate was 72.5%.Conclusions:The manifestations of PVRL are complex and diverse, and most of them are accompanied by involvement of the central nervous system. It can be divided into vitreitis type, retinal type and vitreoretinal type, and the optic nerve can be involved at the same time; IVM combined with systemic treatment can completely relieve the disease.
ABSTRACT
Objective:To observe the clinical features and prognosis of eyes with corneal suture-related infective endophthalmitis.Methods:A retrospective interventional case series. From January 2020 to December 2021, 5 patients (5 eyes) with corneal suture-related infectious endophthalmitis diagnosed by ophthalmic examination at Department of Ophthalmology of the Eye-ENT Hospital of Fudan University were included in the study. Among them, there were 3 males and 2 females; all had unilateral disease; the mean age was 30.80±21.98 years. Sutures of 4 cases were secondary to lens related surgery and of 1 case was secondary to penetrating keratoplasty. Average retention time of corneal suture was 20.00±7.41 months. Of the 5 eyes, corneal sutures were removed in 1 eye due to redness and eye pain in another hospital; 3 eyes were loosened of the sutures in the remaining 4 eyes. The patients were given standard treatment for infectious endophthalmitis, including systemic and local anti-infective therapy; corneal suture removal, intraocular injection, and vitrectomy (PPV). In PPV, it was decided whether to give silicone oil filling according to the situation. The follow-up time after treatment was 11.00±7.38 months. The best corrected visual acuity (BCVA), B-mode ultrasound and microbial culture results of the affected eye before and after surgery were observed and analyzed.Results:Infiltrates, ulcers, or abscesses surrounding the suture may be seen on the cornea of the affected eye. B-mode ultrasonography showed vitreous opacity, preretinal cords, and spherical wall edema in the entire segment of the affected eye. The results of vitreous humor culture were positive in 3 eyes, which were Streptococcus viridis, Staphylococcus hominis subspecies, Staphylococcus epidermidis. After treatment, all the intraocular infections in the affected eyes were successfully controlled, and there were no cases of enucleation of ocular contents or enucleation. Before treatment, the BCVA of the affected eye was from no light perception to counting fingers; after treatment, 2 eyes had BCVA> 0.3.Conclusions:Infiltration, ulcers or abscesses around the sutures can be seen in the cornea of corneal suture-related infective endophthalmitis patients, which are related to the long-term retention of the sutures in the eye. Most of the affected eyes have loose sutures when they go to the doctor; timely treatment can effectively control the infection, and some eyes have good visual prognosis.
ABSTRACT
Objective:To investigate clinical efficacy and safety of dupilumab in the treatment of atopic dermatitis (AD) .Methods:An ambispective study was conducted on 123 AD patients treated with dupilumab in Department of Dermatology, the Second Xiangya Hospital of Central South University from July 2020 to March 2022, clinical data were collected, and efficacy and safety of dupilumab were evaluated. Primary outcomes included scores of eczema area and severity index (EASI) , patient-oriented eczema measure (POEM) , peak pruritus numerical rating scale (NRS) and dermatology life quality index (DLQI) before and after 4-, 8-, 12- and 16-week treatment, and adverse reactions and events were recorded. Comparison of scores before and after treatment was performed using paired t test or repeated measures analysis of variance, Mann-Whitney U test was used for the comparison of efficacy among patients with different types of skin lesions or different IgE levels, and multiple regression model based on robust standard errors was used to analyze factors influencing the efficacy. Results:Among the 123 AD patients, 107 were enolled into the efficacy analysis, and 85 (79.44%) completed at least 4 weeks of treatment, including 6 (7.06%) achieving EASI75 and 23 (27.06%) achieving EASI50, and the EASI, NRS, POEM, DLQI scores (10.41 ± 6.72, 4.12 ± 1.74, 8.60 ± 4.29, 7.81 ± 4.38, respectively) significantly decreased compared with those before treatment (18.08 ± 10.69, 7.21 ± 2.01, 16.88 ± 5.74, 12.95 ± 5.95, respectively; all P < 0.001) in the 85 patients. Among the 107 patients, 47 (43.93%) completed at least 16 weeks of treatment. Among the 47 patients, 23 (82.14%) of 28 adults and 17 (89.47%) of 19 adolescents and children achieved 75% or greater improvement in EASI score; the EASI, NRS, POEM and DLQI scores before the treatment all significantly differred from those 4, 8, 12, 16 weeks after the treatment (all P < 0.001) , and all the scores were significantly lower at weeks 4, 8, 12 and 16 than at the previous adjacent time points (all P < 0.05) . At week 4 during the treatment, the EASI improvement rate was significantly lower in the AD patients with prurigo nodularis than in those without ( U = 151.00, P = 0.006) , while there was no significant difference in the EASI improvement rate between the AD patients with xeroderma and those without ( P > 0.05) ; at week 16 during the treatment, there was no significant difference in the EASI improvement rate between patients with prurigo nodularis or xeroderma and those without (both P > 0.05) . Multiple regression analysis based on robust standard errors at week 16 showed that the improvement degree in the EASI score was not correlated with the type of skin lesions ( β = 3.20, P = 0.075) , but correlated with age ( β = -0.22, P = 0.030) , whether patients were in adulthood ( β = 9.54, P = 0.049) , immediate family history ( β = 7.46, P = 0.017) ; the improvement degree in the NRS score was correlated with the type of skin lesions ( β = 0.55, P = 0.032) , age ( β = -0.04, P = 0.033) , weight ( β = -0.05, P = 0.020) , whether patients were in adulthood ( β = 2.06, P = 0.003) and whether patients received combined treatment with antihistamines ( β = -1.91, P = 0.001) . Adverse reactions: among the 123 patients, 6 (4.88%) developed conjunctivitis, and 2 (1.63%) developed facial erythema. Adverse events: vitiligo-like changes occurred on the right forehead of 1 patient, and 3 patients discontinued the treatment with dupilumab due to Henoch-Sch?nlein purpura, distal axonal damage in peripheral nerves in both upper limbs, and epilepsy, respectively. The causal relationship between these adverse events and dupilumab was unclear. Conclusion:Dupilumab is effective in the treatment of AD with high overall safety, and can serve as a new treatment option for AD patients with an unsatisfactory response to traditional treatment.
