ABSTRACT

Objective:To analyze clinical characteristics and genetic characteristics of children with ATP sensitive potassium passage (K ATP-HI). Methods:Forty-five children with genetically confirmed K ATP-HI and their families admitted to Beijing Children′s Hospital of Capital Medical University between February 2002 and December 2018 were selected as the study subjects. A detailed retrospective analysis of the patient's clinical characteristics, diagnosis and treatment process, disease-causing gene carrying status and later follow-up data was performed. ABCC8/KCNJ11 gene was sequenced by second-generation sequencing technology. Results:Among 45 children with K ATP-HI, 34 cases (75.6%) were neonatal onset, the first symptoms of 21 cases (46.7%) were convulsions. 39 cases had been treated with diazoxide, including 12 cases (30.8%) with good efficacy, 16 cases (41%) with poor efficacy and 11 cases with uncertain efficacy. Octreotide was further applied in 18 patients with uncertain or ineffective efficacy after diazoxide treatment, and 13 cases (72.2%) were effective, 3 cases were ineffective, and 2 cases were uncertain. 10 CHI patients who were ineffective to drug treatment or had clearly focal lesions confirmed by 18F-dopa positron emission by computed tomography ( 18F-DOPA PET) scans had undergone surgical treatment, 8 of which underwent partial pancreatectomy and blood glucose returned to normal after the operation; the other 2 cases underwent subtotal pancreatectomy and both had secondary diabetes after operation. Among 45 children with K ATP-HI, 1 case carried both ABCC8 and KCNJ11 mutations, 10 cases carried ABCC8 compound heterozygous mutations, and the remaining 34 cases carried ABCC8/KCNJ11 single genetic mutation. Among them, 21 cases had paternal inheritance, and 3 cases had maternal inheritance, 6 cases were identified with de novo mutations. Conclusions:Diazoxide treatment was ineffective for most K ATP-HI children, but octreotide had a higher effective rate. Partial pancreatectomy for focal type patients had a higher cure rate, and there was a risk of secondary diabetes after subproximal pancreatectomy, so it was very important to clarify the histological type of children before surgery. ABCC8 gene mutations and KCNJ11 gene mutations were the main pathogenic genes of K ATP-HI. Among patients carrying mutations in single ABCC8 or KCNJ11 gene mutation, K ATP-HI inherited by paternity were the majority. Some K ATP-HI children can relieve the hypoglycemia symptoms by themselves.

ABSTRACT

The sacrum is a common site of stress injury. The occurrence of pressure ulcers not only leads to the aggravation of the patient′s condition, the prolongation of hospital stay, the increase of medical costs, the decline of life quality, but also aggravates the burden of society, family and medical staff. Early reasonable and effective application of sacral dressing can prevent the occurrence of pressure injury. In this study, the characteristics and effectiveness of different types of sacral dressings were reviewed by reviewing relevant literatures at home and abroad and summarizing the existing relevant studies, so as to provide guidance for clinical application.

ABSTRACT

ObjectiveTo observe the effects of Scutellariae Radix (SR)-Paeoniae Radix Rubra (PRR) combination of different proportions on the expression of the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear transcription factor κB (NF-κB) and phosphatidylinositol kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathways in liver tissues of rats with hepatic fibrosis and explore the mechanism against hepatic fibrosis. MethodSixty male SD rats of SPF grade were randomly divided into a normal group, a model group, a positive control (silymarin) group, and SR-PRR 1∶1, SR-PRR 1∶2, and SR-PRR 1∶4 groups, with 10 rats in each group. The hepatic fibrosis model was induced in rats except for those in the normal group by intraperitoneal injection of 40% tetrachloromethane (CCl4)-olive oil solution at 3 mL·kg-1, 5 mL·kg-1 for the first time, for 8 weeks, twice per week. After 4 weeks, rats were treated correspondingly at 10 mL·kg-1 by intragastric administration, and the body weight of rats in each group was weighed for 8 weeks. After administration, histopathological changes in the liver were observed. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN), albumin (ALB), alkaline phosphatase (AKP), and superoxide dismutase (SOD) activities, malondialdehyde (MDA), and hydroxyproline (HYP) content in liver tissues were detected. The mRNA expression levels of TLR4, MyD88, NF-κB, PI3K, Akt, and mTOR in the liver of rats were detected by real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR). ResultCompared with the model group, SR-PRR combination of different proportions could recover the body weight and improve the pathological injury of the liver. As revealed by enzyme linked immunosorbent assay (ELISA) results, compared with the normal group, the model group showed increased ALT, AST, HA, LN, AKP, MDA, and HYP levels to different degrees (P<0.05). Compared with the model group, the groups with drug intervention showed decreased levels of ALT, AST, HA, LN, AKP, MDA, and HYP, potentiated SOD activity, and increased level of ALB (P<0.05). As revealed by Real-time PCR results, compared with the normal group, the model group showed increased mRNA expression of TLR4, MyD88, NF-κB, PI3K, Akt, and mTOR (P<0.05). Compared with the model group, the groups with drug intervention showed reduced mRNA expression of TLR4, MyD88, NF-κB, PI3K, Akt, and mTOR in the liver of rats (P<0.05). ConclusionSR-PRR combination of different proportions can improve the histopathological injury in liver tissues caused by CCl4, with the optimal effect observed in the SR-PRR 1∶4 group. SR-PRR may inhibit the development of liver fibrosis by inhibiting the expression of TLR4/MyD88/NF-κB and PI3K/Akt/mTOR signaling pathways, thereby alleviating chemical-induced liver injury.

ABSTRACT

ObjectiveTo explore the therapeutic effect and mechanism of Huangqi Chifengtang on middle cerebral artery embolism(MCAO) rat model. MethodThe 90 SPF male rats were randomly divided into sham operation group, model group, high, medium and low dose groups of Huangqi Chifengtang (8.10,4.05,2.025 g·kg-1) and positive drug group (Naoxintong 0.32 g·kg-1). MCAO rat model was established and intervened with Huangqi Chifengtang, and the neurological scores of each group were scored. The area of cerebral infarction was calculated by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Serum interleukin-6 (IL-6) and interleukin-1β(IL-1β) were detected by enzyme-linked immunosorbent assay (ELISA),The contents of matrix metalloproteinase-9(MMP-9), vascular endothelial growth factor(VEGF) and vascular endothelial growth factor receptor 2 (VEGFR2), the pathological changes of brain tissue in each group were observed by hematoxylin eosin (HE) staining. Western blot was used to detect zonule atresia protein-1(ZO-1), tight junction protein-5(Claudin-5) and P-glycoprotein (P-gp) and multidrug resistance protein 1(MRP1). ResultCompared with the sham operation group, the neurological function score and cerebral infarction rate of the model group were significantly increased(P<0.01), and the levels of IL-6, IL-1β and MMP-9 in serum were significantly increased(P<0.01), the levels of ZO-1 and Claudin-5 protein expression decreased significantly(P<0.01), and the levels of P-gp and MRP1 protein expression increased significantly(P<0.01). Compared with the model group, the neurological function score of rats in each administration group decreased significantly at 14 days (P<0.05,P<0.01), the pathological changes of brain tissue effectively improved, the rate of cerebral infarction significantly reduced (P<0.01), and the expression level of IL-6, IL-1β and MMP-9 in serum decreased significantly (P<0.05,P<0.01), the content of VEGFR2 increased significantly (P<0.01), and the content of VEGF increased significantly in high, medium dose and positive drug groups (P<0.05,P<0.01). Although it decreased in low dose group, there was no significant difference. The levels of ZO-1 and Claudin-5 protein expression in brain tissue of high dose group and positive drug group increased significantly (P<0.05,P<0.01), the level of MRP1 and P-gp protein expression decreased significantly (P<0.05). ConclusionHuangqi Chifengtang can play a therapeutic role in rats with cerebral infarction by improving the pathological changes of brain tissue, reducing inflammatory reaction, promote angiogenesis and regulating the function of blood-brain barrier(BBB).

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of deep vein thrombosis (DVT) prevention among real-world surgical inpatients who received panax notoginseng saponins (PNS) combined with low-molecular-weight heparin (LMWH).@*METHODS@#A prospective cohort study was conducted among surgical patients between January 2016 and November 2018 in Xuanwu Hospital, Capital Medical University, Beijing, China. Participants received LMWH alone or PNS combined with LMWH for preventing DVT. The primary outcome was incidence of lower extremity DVT, which was screened once a week. Participants in the LMWH group were given LMWH (enoxaparin) via hypodermic injection, 4000-8000 AxalU once daily. Participants in the exposure group received PNS (Xuesaitong oral tablets, 100 mg, 3 times daily) combined with LMWH given the same as LMWH group.@*RESULTS@#Of the 325 patients screened for the study, 281 participants were included in the final analysis. The cohort was divided into PNS + LMWH group and LMWH group with 134 and 147 participants, respectively. There was a significant difference of DVT incidence between two groups (P=0.01), with 21 (15.7%) incident DVT in the PNS + LMWH group, and 41 (27.9%) incident DVT in the LMWH group. Compared with participants without DVT, the participants diagnosed with DVT were older and had higher D-dimer level. The multivariate logistic regression model showed a significant lower risk of incident DVT among participants in the PNS + LMWH group compared with the LMWH group (odds ratio 0.46, 95% confidence interval, 0.25-0.86). There were no significant differences in thromboelaslography values (including R, K, Angle, and MA) and differences in severe bleeding between two groups. No symptomatic pulmonary embolism occurred during the study.@*CONCLUSION@#Combined application of PNS and LMWH can effectively reduce the incidence of DVT among surgical inpatients compared with LMWH monotherapy, without increased risk of bleeding.

ABSTRACT

Objective: To investigate the safety, efficacy, locally control and survival results of transoral Da Vinci robotic surgery for salvage treatment of locally recurrent nasopharyngeal carcinoma. Methods: This retrospective study included 33 patients with locally recurrent nasopharyngeal carcinoma (stage rT1-2, partial rT3) underwent transoral Da Vinci robotic surgery between October 2017 and January 2020. There were 20 males and 11 females, with an average age of (47.9±10.5) years. The lesions were localized in nasopharyngeal cavity in 14 cases, with extending to parapharyngeal space in 6 cases and the floor of sphenoid sinus in 13 cases. Transnasal endoscopy was used to assist surgery if necessary. SPSS 25.0 statistical software was used for statistical analysis. Results: Transoral robotic nasopharyngectomy was successfully performed in all cases without conversion to open surgery, of which 13 cases were combined with transnasal endoscopic surgery. The average operation time was (126.2±30.0) min, ranging from 90 to 180 min. The postoperative pathological margin was R0 (31 cases) and R1 (2 cases), with no tumor residue. Complications of surgery mainly included symptoms of headache, nasal dryness and velopharyngeal insufficiency without nasopharyngeal hemorrhage. Follow-up time was from 3 to 54 months. One case had tumor recurrence 11 months after operation, 1 case had ipsilateral cervical lymph node metastasis 27 months after operation, 2 cases had distant metastasis and 1 case died of nasopharyngeal hemorrhage 3 months after operation. The 1-year, 2-year and 3-year overall survival rates were 97.0%, 96.0% and 92.9%, respectively and the local recurrence free rates were 97.0%, 95.7% and 91.7%, respectively. Conclusion: Transoral robotic nasopharyngectomy is safe and feasible for local recurrent nasopharyngeal carcinoma in selected patients, with higher local control rate and quality of life.

ABSTRACT

OBJECTIVE@#To evaluate the accuracy of trephine bur drilling at different depths guided by dynamic navigation system in 3D printing in vitro model.@*METHODS@#A model at the depth of 5 mm, 10 mm, and 15 mm from the outer surface of which hemispherical cavities was reserved and the 3D printing technology was used to make the standardized model with Veroclear resin. The cone beam CT (CBCT) was taken and the data were imported into the dynamic navigation software (DCARER, China) to establish navigation path programming. Under the guidance of dynamic navigation, a trephine bur with a diameter of 4.5 mm was used to complete the access operation. At each depth, 10 approaches were completed. The postoperative model CBCT was taken. The approach trajectory under navigation was reconstructed and compared with the designed path. The two-dimensional distance deviation, depth deviation, three-dimensional distance deviation, and angle deviation between the actually prepared path and the designed path were calculated.@*RESULTS@#At the depth of 5 mm, the two-dimensional distance deviation between the end position of the prepared path and the designed path was (0.37±0.06) mm, the depth deviation was (0.06±0.05) mm, the three-dimensional distance deviation was (0.38±0.07) mm, and the angle deviation was 2.46°±0.54°; At the depth of 10 mm, the four deviations between the end position of prepared path and the designed path were (0.44±0.05) mm, (0.16±0.06) mm, (0.47±0.05) mm, and 2.45°±1.21°, respectively; At the depth of 15 mm, the four deviations were (0.52±0.14) mm, (0.16±0.07) mm, (0.55±0.15) mm, and 3.25°±1.22°, respectively. With the increase of entry depth, the three-dimensional and depth accuracy of dynamic navigation system decreased (P < 0.01), and the positioning angle deviation had no relation with the entry depth (P>0.01).@*CONCLUSION@#Dynamic navigation technology can achieve high positioning accuracy in the depth range of 15 mm, but its deviation increases with the increase of entry depth.

ABSTRACT

Objective: To analyze the clinical characteristics and prognostic value of liver function in a large samples of patients with anti-glycoprotein 210 (gp210 antibody) positive primary biliary cholangitis (PBC). Methods: A retrospective study was performed on 931 PBC cases in Beijing You'an Hospital affiliated to Capital Medical University from 2010 to 2019. According to the detection of gp210 antibody, 318 cases were divided into gp210 antibody positive group (positive group) and 613 cases were divided into gp210 antibody negative group (negative group). The differences in demographic, medical history, clinical indicators, B-ultrasound and pathological indicators as well as the histopathological basis were compared between the two groups. SPSS 16.0 software was used for statistical analysis. Measurement data were analyzed by t-test or rank sum test, and enumeration data by χ2 test. Multivariate analysis was used for logistic test, and and survival analysis was used for prognosis. Results: The positive and the negative groups were compared. The ratio of male to female was significantly higher in positive than negative group (1:5.35 vs. 1:9.73, P<0.05), and the difference was statistically significant. The proportion of hormone use in history of past diagnosed and treated was higher in positive than negative group (12.9% vs. 3.47%, P<0.05), and the difference was statistically significant. The detection of biochemical indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT) were higher in positive than the negative group (51.1 U/L vs. 41.1 U/L, 62.6 U/L vs. 49.6 U/L, 24.1 μmol/L vs. 17.9 μmol/L, 228.3 U/L vs. 169.6 U/L, 203.9 U/L vs. 147.6 U/L), (P<0.05), and the differences were statistically significant. Antinuclear antibody (ANA)-positive rate, high titer ratio and immunoglobulin G (IgG) levels were higher in positive than negative group (95.2% vs. 81.6%, 69.7% vs. 48.8%, 17.2 g/L vs. 16.2 g/L), (P<0.05), and the differences were statistically significant. The incidence of liver failure was higher in positive than negative group (P<0.05). CK7 and inflammation score were higher in positive group than negative group in liver histopathological observations (0.83±0.53 vs. 0.28±0.47; 1.06±0.39 vs. 0.54±0.65), (P<0.05), and the differences were statistically significant. Conclusion: The illness condition of patients with gp210 antibody positive PBC is more severe than patients with gp210 antibody negative PBC, and the incidence of liver failure is significantly increased. Cholangiocytes may be the histopathological basis of the clinical characteristics of gp210 antibody positive PBC patients.

ABSTRACT

Objective: To evaluate the diagnostic value of transient elastography, aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis index based on 4 factors (FIB-4) for liver fibrosis in children with non-alcoholic fatty liver disease (NAFLD). Methods: A retrospective study was conducted on 100 cases of nonalcoholic fatty liver disease in Hunan Children's Hospital between August 2015 to October 2020 to collect liver tissue pathological and clinical data. The receiver operating characteristic curve (ROC curve) was used to analyze the diagnostic value of liver stiffness measurement (LSM), APRI and FIB-4 in the diagnosis of different stages of liver fibrosis caused by NAFLD in children. Results: The area under the ROC curve (AUC) value of LSM, APRI and FIB-4 for diagnosing liver fibrosis (S≥1) were 0.701 [95% confidence interval (CI): 0.579 ~ 0.822, P = 0.011], 0.606 (95%CI: 0.436 ~ 0.775, P = 0.182), and 0.568 (95%CI: 0.397 ~ 0.740, P = 0.387), respectively. The best cut-off values were 6.65 kPa, 21.20, and 0.18, respectively. The AUCs value of LSM, APRI, and FIB-4 for diagnosing significant liver fibrosis (S≥ 2) were 0.660 (95% CI: 0.552 ~ 0.768, P = 0.006), 0.578 (95% CI: 0.464 ~ 0.691, P = 0.182) and 0.541 (95% CI: 0.427 ~ 0.655, P = 0.482), respectively. The best cut-off values were 7.35kpa, 24.78 and 0.22, respectively. The AUCs value of LSM, APRI and FIB-4 for the diagnosis of advanced liver fibrosis (S≥ 3) were 0.639 (95% CI: 0.446 ~ 0.832, P = 0.134), 0.613 (95% CI: 0.447 ~ 0.779, P = 0.223) and 0.587 (95% CI: 0.411 ~ 0.764, P = 0.346), respectively. The best cut-off values were 8.55kpa, 26.66 and 0.27, respectively. Conclusion: The transient elastography technique has a better diagnostic value than APRI and FIB-4 for liver fibrosis in children with NAFLD.

ABSTRACT

Objective: To investigate the efficacy and safety of adrenocorticotropic hormone (ACTH) in children with frequently relapsing or steroid-dependent nephrotic syndrome. Methods: The clinical data of 38 children with frequently relapsing or steroid-dependent nephrotic syndrome who were admitted to the Department of Nephrology, the Children Hospital, Zhejiang University School of Medicine from January 2015 to December 2020 were retrospectively analyzed. The general information, clinical manifestations, laboratory data of the children and follow-up (till 12 months after treatment) were collected. The patients were divided into ACTH group and Glucocorticoid (GC) group according to treatment plan. Cumulative remission, average recurrence rate, GC dosage, height and weight change and peripheral blood CD19+B lymphocyte count were compared between the two groups to evaluate the efficacy and adverse reactions of ACTH. Fisher's exact test, t test or rank sum test was used for comparison between groups. Results: Among the 38 patients, 28 were male and 10 were female, aged 84 (24, 180) months; 19 were in ACTH group and 19 were in GC group. The cumulative remission rate of 12 months in ACTH group was higher than that in GC group (9/19 vs. 2/19,χ²=6.81,P=0.009), the average recurrence rate was lower than that in GC group ((0.7±0.8) vs. (1.7±1.1) times, t=-3.27, P=0.011), and the average dosage of GC was lower than that in GC group ((0.27±0.16) vs. (0.51±0.27) mg/(kg·d), t=-3.21, P=0.014). The increase in height was higher than that in the GC group (4 (3,5) vs. 3 (2, 3) cm/year, Z=2.58, P=0.010), and the peripheral blood CD19+B lymphocyte count was lower than that in the GC group ((223±149)×106 vs. (410±213)×106/L,t=-3.35, P=0.009). In safety, 19 cases had transient decreased urine volume, 7 cases had hyperglycemia, and 3 cases had hypertension during the infusion of ACTH, which could be relieved after drug withdrawal. Conclusion: ACTH has a better effect on children with frequently relapsing or steroid-dependent nephrotic syndrome, which can improve cumulative sustained remission rate, lower relapses rate and decrease the dosage of GC, with good safety.

ABSTRACT

Objectives: To examine the impact of probiotics on the lung development of preterm birth of Bama pig. Methods: From April 2020 to October 2021, this animal experimental research was performed by setting up preterm (birth at gestation 104 d), full-term (birth at gestation 113 d), preterm with probiotics (birth at gestation 104 d treated with probiotics given at 3 d after birth), and full-term with probiotics (birth at gestation 113 d treated with probiotics given at 3 d after birth) groups and using the preterm Bama minipig model, the body weights were recorded and lung, ileum, and intestinal content samples were collected at birth, 4 days, 9 days, and 21 days after births of the piglets in preterm and full-term groups, the same samples were collected on 9 days after births of the piglets in preterm with probiotics and full-term with probiotics groups. The body weight and radial alveolar counts (RAC) were compared to evaluate the lung development of the piglets. The lengths of ileal villus were compared to evaluate the development of ileum. The composition structures of bacteria in ileum were analyzed by 16 S rRNA sequencing. The statistical analyses between different groups were performed by t test. Results: There were totally 30 piglets (16 female piglets and 14 male piglets) involving 12 piglets in preterm and full-term groups respectively and 3 piglets in preterm with probiotics and full-term with probiotics groups respectively. The body weights of the piglets in preterm group were lower than those in full-term group at 4, 9 and 21 d after birth ((507±27) vs. (694±56) g, (620±35) vs. (1 092±154) g, (1 660±210) vs. (2 960±418) g,t=2.96, 2.99, 2.78, all P<0.05). The alveolarization of the preterm piglets at 9 days after birth was significantly lower than that of the full-term piglets at the equivalent time point (4.00±0.29 vs. 6.11±0.35, t=4.64, P<0.01). The bacteria genus with the highest abundance in ileum were all different between the preterm and the full-term groups at 4, 9 and 21 d after birth (4 d Escherichia-Shigella (26.63%) and Enterococcus (30.48%) respectively;9 d Turicibacter (35.94%) and Lactobacillus (27.33%) respectively;21 d Escherichia-Shigella (28.02%) and Lactobacillus (46.29%) respectively). The heights of ileal villus of the preterm piglets at 9 d after birth were significantly lower than those of the full-term minipigs at the equivalent time point ((297±21) vs. (411±32) μm, t=3.01, P=0.007).There were both no differences in the body weight and alveolarization ((692±36) vs. (767±67) g, 5.44±0.34 vs. 5.89±0.26, t=0.74, 1.04, both P>0.05) between the piglets in preterm with probiotics group and those in full-term with probiotics group. Turicibacter was the dominant genus in the piglets of both preterm with probiotics and the full-term with probiotics groups. The heights of ileal villus of the piglets in preterm with probiotics group were significantly longer that those of the piglets in preterm group ((371±13) vs. (297±21) μm, t=3.04, P=0.006), and were both not significantly different from those of the piglets in full-term with probiotics group and full-term group ((371±13) vs. (338±12) and (411±32) μm, t=1.90, 1.15, both P>0.05). Conclusions: Premature birth could impact the lung alveolarization of piglets. The probiotics could improve the lung alveolarization of preterm minipigs by promoting the development of ileum.

ABSTRACT

Objective:To observe the effect of combining biofeedback therapy (BFT) based on virtual reality technology with repeated transcranial magnetic stimulation (rTMS) on dysphagia among stroke survivors.Methods:Eighty patients were randomly divided into a control group, an rTMS group, a BFT group and a combined treatment group, each of 20. In addition to routine dysphagia rehabilitation, the rTMS and BFT groups were given those treatments, while the combined treatment group was given both for 4 weeks. Swallowing function was evaluated before and after the treatment using the standardized swallowing assessment (SSA) and the functional oral intake scale (FOIS). Videofluoroscopy was used to quantify the subjects′ oral and pharyngeal phases and their aspiration status.Results:Significant improvement was observed in the average FOIS and SSA scores, as well as in the average oral and pharyngeal phases and in aspiration. The combined treatment group′s results were significantly better in all those aspects than those of the other 3 groups.Conclusion:The combined application of biofeedback therapy based on virtual reality technology and repeated transcranial magnetic stimulation can improve the swallowing function of stroke survivors with dysphagia. It is worthy of clinical promotion.

ABSTRACT

Objective:To investigate the correlation between sleep quality and risk of female complicated vulvovaginal candidiasis (VVC).Methods:From January 2021 to June 2021, patients in the gynecological clinic of Xiangya Hospital of Central South University were continuously enrolled as the research objects using a cross-sectional survey. A self-made questionnaire was used to collect the age, marital status, education level, family monthly income, place of residence in the past two years, maternity history, number of births, intrauterine device, number of abortions, frequency of sex life, use of contraceptives within two months, use of antibacterial drugs within two weeks. Generalized Anxiety Disorder Scale, Patient Health Questionnaire, Health Questionnaire Somatic Symptom Group Scale, Pittsburgh Sleep Quality Index were used to collect patients′ anxiety, depression, somatization symptoms, and sleep quality conditions. The total scores of sleep quality and the scores of each dimension were used as observation indicators. Three logistic regression analysis models were constructed to explore the relationship between sleep quality and complicated VVC groups.Results:Patients in the complex VVC group were significantly higher in age, married, middle school education, rural area of residence in the last two years, birth history, number of births ≥3, sexual frequency≥1/week, and no antibiotic use within two weeks compared to those in the control group (all P<0.05). Without adjusting for confounding factors, women with poor subjective sleep quality had a 6.73-fold increased risk ( OR=7.73, 95% CI: 3.22-18.55) of complex VVC compared with those with good subjective sleep quality. After adjusting for confounding factors, the risk was further increased to 9.08 fold ( OR=10.08, 95% CI: 3.47-29.33)(all P<0.05). Compared with women without sleep disorders, women with mild sleep disorders had a 97% increased risk of complex VVC ( OR=1.97, 95% CI: 1.15-3.37). After adjusting for confounders, the risk remained 97% higher ( OR=1.97, 95% CI: 1.10-3.55)(all P<0.05). Conclusion:Poor subjective sleep quality and mild sleep disorder may be associated with the risk of complex VVC.

ABSTRACT

Objective:To investigate the prognostic value of pretreatment 18F-FDG PET/CT metabolic parameters in patients with elderly classical Hodgkin′s lymphoma (cHL). Methods:From April 2011 to April 2020, the pretreatment clinical and 18F-FDG PET/CT metabolic parameters of 42 elderly cHL patients (29 males and 13 females, median age 69 years) pathologically confirmed in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were obtained with 41%SUV max as the threshold. ROC curve analysis was applied to obtain the best prognostic cut-off value of SUV max, MTV and TLG. Kaplan-Meier method and log-rank test were used for univariate survival analysis, and Cox proportional hazard regression model was used for multivariate survival analysis. Results:SUV max, MTV and TLG of 42 elderly cHL patients were 16.49(12.24, 23.59), 79.29(26.29, 184.51) ml and 729.02(206.03, 2 073.98) g, respectively. ROC curve showed that the AUCs of SUV max, MTV and TLG were 0.425, 0.882 and 0.832, respectively, and the best prognostic cut-off values were 16.49, 82.38 ml and 556.26 g, respectively. Univariate analysis showed that age, B symptoms, lactate dehydrogenase (LDH) level, Hb content, Ann Arbor stage, German Hodgkin Study Group (GHSG) score, MTV and TLG were relative factors affecting progression-free survival (PFS) rate ( χ2 values: 4.50-12.60, all P<0.05), and age, B symptoms, LDH level, Ann Arbor stage, GHSG score, MTV and TLG were relative factors affecting overall survival (OS) rate ( χ2 values: 5.20-11.17, all P<0.05). Multivariate analysis showed that MTV (relative risk ( RR)=5.370, 95% CI: 1.697-16.277) and TLG ( RR=4.854, 95% CI: 1.228-23.352) were independent prognostic predictors of PFS rate (both P<0.05), and GHSG score ( RR=3.761, 95% CI: 1.092-12.955; RR=3.668, 95% CI: 1.068-12.571), MTV ( RR=6.173, 95% CI: 1.431-16.322) and TLG ( RR=5.162, 95% CI: 1.200-22.199) were independent prognostic predictors of OS rate (all P<0.05). Conclusion:MTV and TLG in pretreatment 18F-FDG PET/CT are independent prognostic factors for predicting PFS and OS in patients with elderly cHL patients, which have certainly reference value for prognosis.

ABSTRACT

Objective:To compare the dosimetry and efficacy of intracavitary brachytherapy (ICBT) and intracavitary/interstitial brachytherapy (IC+ ISBT) based on CT image guidance in the treatment of stage Ⅲ B cervical cancer. Methods:Clinical data of 93 patients with stage Ⅲ B cervical cancer treated in Department of Radiotherapy of Jilin Cancer Hospital from June 2014 to February 2017 were analyzed retrospectively. According to the results of Gynecological examination and pelvic MRI before brachytherapy, confirming the size of residual tumor and the degree of parauterine infiltration, all patients were divided into the ICBT and IC+ ISBT groups. The D 90%, D 100%, V 100% and D 2cm 3 of bladder and rectum were compared, and the short-term and long-term efficacy was observed between two groups. Results:The median follow-up time was 60 months. The 5-year local control rate, distant metastasis-free survival rate and overall survival rate of all patients were 83%, 71% and 68%, respectively. Compared with the ICBT group, HR-CTV D 90% in the IC+ ISBT group was all more than 85 Gy, while there was no significant difference between two groups ( P=0.188). The D 2cm 3 of bladder and rectum in the IC+ ISBT group was significantly decreased by 7 Gy and 8 Gy (both P<0.01), and the distant metastasis-free survival rate was significantly improved ( P=0.009). The 5-year local control rate in the HR-CTV volume>60 cm 3 in the IC+ ISBT group was significantly higher than that in the IC group ( P=0.029). Conclusion:For patients with Ⅲ B cervical cancer, IC+ ISBT can not only ensure target coverage, but also significantly reduce the incidence of distant metastasis and the dose of organs at risk, and significantly improve the local control rate of large tumors.

ABSTRACT

Objective:To analyze locoregional recurrence (LRR) pattern of patients with pT 1-2N 1 breast cancer after modified radical mastectomy, with and without adjuvant radiotherapy (RT). Methods:A total of 5442 eligible patients with breast cancer from 12 Chinese centers were included. The LRR sites and the effect of RT at different sites on recurrence in patients with and without RT were analyzed. The Kaplan-Meier method was used to calculate the cumulative LRR rate, and the difference was compared by the log-rank test.Results:With a median follow-up time of 63.8 months for the entire cohort, 395 patients developed LRR. The chest wall and supraclavicular fossa were the most common LRR sites, regardless of RT or molecular subtypes. The 5-year chest wall recurrence rates for patients with and without chest wall irradiation were 2.5% and 3.8%( P=0.003); the 5-year supraclavicular lymph nodal recurrence rates for patients with and without supraclavicular fossa irradiation were 1.3% and 4.1%( P<0.001); the 5-year axillary recurrence-free rates for patients with and without axillary irradiation were 0.8% and 1.5%( HR=0.31, 95% CI: 0.04-2.23, P=0.219); and the 5-year internal mammary nodal recurrence-free rates for patients with and without internal mammary nodal irradiation were 0.8% and 1.5%( HR=0.45, 95% CI: 0.11-1.90, P=0.268). Conclusions:The chest wall and supraclavicular fossa are the most common LRR sites of patients with pT 1-2N 1 breast cancer after modified radical mastectomy, which is not affected by adjuvant RT or molecular subtypes. The chest wall and supraclavicular fossa irradiation significantly reduce the risk of recurrence in the corresponding area. However, axillary and internal mammary nodal irradiation has no impact on the risk of recurrence in the corresponding area.

ABSTRACT

Objective:To investigate the risk factors for preoperative hypoxemia in geriatric patients with hip fracture.Methods:A case-control study was used to analyze the clinical data of 99 geriatric patients with hip fracture admitted to Zhongda Hospital affiliated to Southeast University between November 2020 and August 2021. There were 29 males and 70 females, aged 67-96 years [(82.6±6.2)years]. The patients were divided into hypoxemia group ( n=51) and non-hypoxemia group ( n=48) using partial arterial partial pressure of oxygen (PaO 2)<80 mmHg while breathing room air at emergency as the reference standard. The two groups were compared in terms of sex, age, fracture types, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, pulmonary diseases diagnosed by preoperative chest CT [atelectasis, pleural effusion, chronic obstructive pulmonary disease (COPD)], time from injury to visit, New York Heart Association (NYHA) classification, Barthel index, KATZ index, modified Medicine Research Council (mMRC) dyspnea scale, numeric rating scale (NRS), smoking, drinking, comorbidities (hypertension, diabetes mellitus, Parkinson′s disease, Alzheimer′s disease, cerebral infarction, coronary atherosclerotic heart disease), body temperature, blood routine test at first examination (erythrocyte count, leukocyte count, C-reactive protein, hemoglobin), biochemistry (serum albumin, blood glucose, blood creatinine, blood urea nitrogen), electrolyte (serum potassium, serum sodium), and other related examinations [D-dimer, brain natriuretic peptide (BNP), lactic acid]. Univariate analysis was performed to the correlation of those indicators with preoperative hypoxemia. Multivariate Logistic regression analysis was used to identify the independent risk factors for preoperative hypoxemia in geriatric patients with hip fracture. Results:Differences in sex, age, fracture types, BMI, pulmonary diseases diagnosed by preoperative chest CT, time from injury to visit, Barthel index, KATZ index, NRS, smoking, drinking, comorbidities, body temperature, first laboratory results of erythrocyte count, biochemistry, electrolyte and other related examinations were not statistically significant between the two groups (all P>0.05). The two groups showed statistical differences in ASA classification, NYHA classification, mMRC dyspnea scale, leukocyte count at first examination, C-reaction protein and hemoglobin (all P<0.05). Univariate analysis indicated that ASA classification, NYHA classification, mMRC dyspnea scale, leukocyte count at first examination and C-reaction protein were correlated with the occurrence of preoperative hypoxemia in geriatric patients with hip fracture (all P<0.05). Multivariate Logistic regressions analysis indicated that higher mMRC dyspnea scale ( OR=2.30, 95% CI 1.10-4.81, P<0.05), higher leukocyte count at first examination ( OR=1.24, 95% CI 1.05-1.45, P<0.05), higher level of C-reaction protein ( OR=1.02, 95% CI 1.01-1.03, P<0.05) and higher level of hemoglobin ( OR=1.04, 95% CI 1.01-1.07, P<0.05) were significantly correlated with the occurrence of preoperative hypoxemia in geriatric patients with hip fracture. Conclusion:Higher mMRC dyspnea scale, higher leukocyte count, higher level of C-reaction protein and higher level of hemoglobin are independent risk factors for preoperative hypoxemia in geriatric patients with hip fracture.
