ABSTRACT

OBJECTIVE To study the effects of Phellodendron amurense polysaccharides (PAP) on improving gouty nephropathy (GN) in rats, and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase (p38 MAPK)/nuclear factor-κB(NF-κB)/tumor necrosis factor-α(TNF-α). METHODS Sixty rats were randomly divided into normal group (water), model group (water), allopurinol group (positive control, 20 mg/kg), PAP high-dose, medium-dose and low-dose groups (100, 50, 25 mg/kg, by raw material) after being stratified by body weight, with 10 rats in each group. Except for the normal group, the other groups were induced to construct GN model by giving 1 500 mg/kg potassium oxazinate and 100 mg/kg adenine intragastrically for 14 days. After modeling, the rats in each group were given relevant medicine/water intragastrically, once a day, for consecutive 28 days. After the last medication, the levels of biochemical parameters related to renal function [uric acid, creatinine (Cr), blood urea nitrogen (BUN), xanthine oxidase (XOD)] were detected in rats, and the histopathological changes in the rat kidney were observed. The protein expressions of monocyte chemoattractant protein-1(MCP-1),TNF-α and interleukin-6(IL-6) as well as the phosphorylation levels of p38 MAPK and NF-κB p65 protein were determined in renal tissue of rats. RESULTS Compared with the normal group, the model group suffered from the dilatation of renal tubules, structural damage to glomeruli, accompanied by inflammatory infiltration and fibrosis; the contents of uric acid, Cr, BUN and XOD, the protein expressions of MCP-1,TNF-α and IL-6 and the phosphorylation levels of p38 MAPK and NF-κB p65 protein were all increased significantly (P<0.05 or P<0.01). Compared with the model group, the pathological symptoms of renal tissue in rats had been improved to varying degrees in different dose groups of PAP; the contents of uric acid, Cr, BUN and XOD, protein expressions of MCP-1, TNF-α and IL-6, the phosphorylation levels of p38 MAPK and NF-κB p65 protein in PAP high-dose and PAP medium-dose groups were all decreased significantly (P<0.05 or P<0.01). CONCLUSIONS PAP exhibits an anti-GN effect, the mechanism of which may be associated with inhibiting the p38 MAPK/NF-κB/TNF-α signaling pathway.

ABSTRACT

Two male patients with bifid rib-basal cell nevus-jaw cyst syndrome (BCNS) were admitted to Department of Stomatology, the First Affiliated Hospital of Bengbu Medical College due to radiological findings of multiple low density shadows in the jaw. Clinical and imaging findings showed thoracic malformation, calcification of the tentorium cerebellum and falx cerebrum as well as widening of the orbital distance. Whole exon high-throughput sequencing was performed in two patients and their family members. The heterozygous mutations of c.C2541C>A(p.Y847X) and c.C1501C>T(p.Q501X) in PTCH1 gene were detected in both patients. Diagnosis of BCNS was confirmed. The heterozygous mutations of PTCH1 gene locus were also found in the mothers of the two probands. Proband 1 showed clinical manifestations of low intelligence, and heterozygous mutations of c.C2141T(p.P714L) and c.G3343A(p.V1115I) were detected in FANCD2 gene. Proband 2 had normal intelligence and no FANCD2 mutation. The fenestration decompression and curettage of jaw cyst were performed in both patients. Regular follow-up showed good bone growth at the original lesion, and no recurrence has been observed so far.

ABSTRACT

Glial cells, consisting of astrocytes, oligodendrocyte lineage cells, and microglia, account for >50% of the total number of cells in the mammalian brain. They play key roles in the modulation of various brain activities under physiological and pathological conditions. Although the typical morphological features and characteristic functions of these cells are well described, the organization of interconnections of the different glial cell populations and their impact on the healthy and diseased brain is not completely understood. Understanding these processes remains a profound challenge. Accumulating evidence suggests that glial cells can form highly complex interconnections with each other. The astroglial network has been well described. Oligodendrocytes and microglia may also contribute to the formation of glial networks under various circumstances. In this review, we discuss the structure and function of glial networks and their pathological relevance to central nervous system diseases. We also highlight opportunities for future research on the glial connectome.

ABSTRACT

Objective To identify the relationship between nephritis activity, autophagy and inflammation in patients with SLE. Methods Western blot analysis was used to detect the expression of microtubule-associated protein 1 light chain 3 (LC3) and P62 in peripheral blood mononuclear cells (PBMCs) of SLE patients with lupus nephritis and non-lupus nephritis patients. Tumor necrosis factor α (TNF-α) and interferon γ (IFN-γ) in the serum of SLE patients were determined by ELISA. The correlation between LC3II/LC3I ratio and SLE disease activity score (SLEDAI), urinary protein, TNF-α and IFN-γ levels was analyzed by Pearson method. Results The expression of LC3 was increased and P62 was decreased in SLE patients. TNF-α and IFN-γ were increased in the serum of SLE patients. LC3II/LC3I ratio was positively correlated with SLEDAI (r=0.4560), 24 hour urine protein (r=0.3753), IFN-γ (r=0.5685), but had no correlation with TNF-α (r=0.04 683). Conclusion Autophagy is found in PBMCs of SLE, and the autophagy is correlated with renal damage and inflammation in patients with lupus nephritis.

ABSTRACT

OBJECTIVE@#To explore the effectiveness of folded transverse superficial epigastric artery perforator flap in repairing the large penetrating defect after buccal carcinoma resection.@*METHODS@#Between January 2019 and June 2021, 12 patients with buccal squamous cell carcinoma were treated. There were 6 males and 6 females with an average of 66.9 years (range, 53-79 years). The pathological stage was T3a-T4b, and the preoperative mouth opening was (3.08±0.46) cm. The disease duration ranged from 6 to 24 months, with an average of 15 months. After buccal carcinoma radical resection and neck lymph node dissection, the penetrating defects in size of 8 cm×6 cm to 16 cm×8 cm and in depth of 0.5-1.5 cm were remained. The transverse superficial epigastric artery perforator flap in size of 8 cm×6 cm to 14 cm×8 cm were harvested and folded to repair the penetrating defects. The donor site was sutured directly.@*RESULTS@#All 12 skin flaps survived after operation, and the wounds healed by first intention. No internal or external fistula complications occurred. All incisions at the recipient site healed by first intention. All patients were followed up 12-18 months (mean, 14 months). There was no obvious abnormality in the color and texture of the flap, the oral and facial appearances were symmetrical, and there was no obvious swelling in the cheek. At last follow-up, the patient's mouth opening was (2.89±0.33) cm, which was not significantly different from that before operation ( t=1.879, P=0.087). The subjective satisfaction scores of 12 patients were 6-8 points, with an average of 7.3 points. Significant scars remained at the donor site but concealed in location.@*CONCLUSION@#The folded transverse superficial epigastric artery perforator flap can be used as a surgical method for repairing large penetrating defects after the buccal carcinoma resection, with a good recovery of facial appearance and oral function.

ABSTRACT

Sweet potato is an important food crop that can also be used as an industrial raw material. Sucrose is the main form of long-distance carbohydrate transport in plants, and sucrose transporter (SUT) regulates the transmembrane transport and distribution of sucrose during plant growth and metabolism. Moreover, SUT plays a key role in phloem mediated source-to-sink sucrose transport and physiological activities, supplying sucrose for the sink tissues. In this study, the full-length cDNA sequences of IbSUT62788 and IbSUT81616 were obtained by rapid amplification of cDNA ends (RACE) cloning according to the transcripts of the two SUT coding genes which were differentially expressed in sweet potato storage roots with different starch properties. Phylogenetic analysis was performed to clarify the classification of IbSUT62788 and IbSUT81616. The subcellular localization of IbSUT62788 and IbSUT81616 was determined by transient expression in Nicotiana benthamiana. The function of IbSUT62788 and IbSUT81616 in sucrose and hexose absorption and transport was identified using yeast functional complementarity system. The expression pattern of IbSUT62788 and IbSUT81616 in sweet potato organs were analyzed by real-time fluorescence quantitative PCR (RT-qPCR). Arabidopsis plants heterologous expressing IbSUT62788 and IbSUT81616 genes were obtained using floral dip method. The differences in starch and sugar contents between transgenic and wild-type Arabidopsis were compared. The results showed IbSUT62788 and IbSUT81616 encoded SUT proteins with a length of 505 and 521 amino acids, respectively, and both proteins belonged to the SUT1 subfamily. IbSUT62788 and IbSUT81616 were located in the cell membrane and were able to transport sucrose, glucose and fructose in the yeast system. In addition, IbSUT62788 was also able to transport mannose. The expression of IbSUT62788 was higher in leaves, lateral branches and main stems, and the expression of IbSUT81616 was higher in lateral branches, stems and storage roots. After IbSUT62788 and IbSUT81616 were heterologously expressed in Arabidopsis, the plants grew normally, but the biomass increased. The heterologous expression of IbSUT62788 increased the soluble sugar content, leaf size and 1 000-seed weight of Arabidopsis plants. Heterologous expression of IbSUT81616 increased starch accumulation in leaves and root tips and 1 000-seed weight of seeds, but decreased soluble sugar content. The results obtained in this study showed that IbSUT62788 and IbSUT81616 might be important genes regulating sucrose and sugar content traits in sweet potato. They might carry out physiological functions on cell membrane, such as transmembrane transport of sucrose, sucrose into and out of sink tissue, as well as transport and unloading of sucrose into phloem. The changes in traits result from their heterologous expression in Arabidopsis indicates their potential in improving the yield of other plants or crops. The results obtained in this study provide important information for revealing the functions of IbSUT62788 and IbSUT81616 in starch and glucose metabolism and formation mechanism of important quality traits in sweet potato.

ABSTRACT

Objective To analyze the current situation and trend of genital herpes disease burden in China from 1990 to 2019, and to provide a theoretical basis for the prevention and treatment of genital herpes. Methods Using the 2019 Global Burden of Disease database, the trend of the burden of genital herpes disease in China from 1990 to 2019 was analyzed using the Joinpoint software based on the indicators of incidence, disability-adjusted life years (DALY) and disability-lost life years. The ARIMA time series model was established to predict the development trend of genital herpes diseases in China from 2020 to 2024. Results From 1990 to 2019, the incidence of genital herpes in China had a downward trend. The incidence of the disease was mainly concentrated in the age group of 15-49 years old, and the DALY rate in this age group showed a significant upward trend (AAPC=0.73, P < 0.001). The age group of 50-69 years old showed a significant upward trend (AAPC=0.09, P < 0.05). The DALY rate of genital herpes in China showed an increasing trend from 1990 to 2019. Between 1990 and 2019, the overall disease burden of women in China was higher than that of men. The ARIMA model predicted that the incidence of genital herpes and DALY rate in China would continue to increase from 2020 to 2024. Conclusion The disease burden of genital herpes in China is still on the rise. It is necessary to strengthen the safe sexual behavior education and actively carry out health education among young and middle-aged people.

ABSTRACT

High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

ABSTRACT

Objective@#To investigate loneliness and associated factors among adolescents with mixed anxiety and depressive disorder(MADD), and to provide reference for drawing up effective and targeted interventions.@*Methods@#Using convenience sampling method, 265 adolescents with MADD in Daqing Third Hospital were selected from September 2020 to June 2021. General information questionnaire, Pittsburgh sleep quality index(PSQI), Resilience Scale for Chinese Adolescents(RSCA), Child and Adolescent Peer Relationship Scale and UCLA Loneliness Scale were used to investigate the status and influencing factors of loneliness among adolescents with MADD.@*Results@#The average score of UCLA among 265 adolescents with MADD was (56.49±10.83). The results of univariate analysis showed that age, gender, burden of medical expenses, drinking behavior and parents migrant work had statistically significant differences in the UCLA scores. The results of Pearson correlation analysis showed that loneliness in MADD adolescents was negatively correlated with psychological resilience( F/t=57.65, -60.62, 21.92, 8.52, 16.22, P <0.01), and positively correlated with sleep quality and interpersonal distress( F/t=-0.69, 0.76, 0.50, P <0.01). The results of multiple stepwise regression analysis showed that phase of study, sex, burden of medical expenses, interpersonal distress, sleep quality and resilience were the influencing factors of loneliness among adolescents with MADD( B=0.11, 0.13, 0.09, 0.46, 0.10,-0.24, P <0.01).@*Conclusion@#Adolescents with MADD have moderate loneliness, which needs to be improved. Nursing staff should pay attention to the negative emotional experience such as loneliness among adolescents with MADD, and reduce their loneliness by improving sleep quality and resilience, reducing interpersonal distress.

ABSTRACT

Objectives: To construct a nomogram incorporating important prognostic factors for predicting the overall survival of patients with colorectal cancer with peritoneal metastases treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), the aim being to accurately predict such patients' survival rates. Methods: This was a retrospective observational study. Relevant clinical and follow-up data of patients with colorectal cancer with peritoneal metastases treated by CRS + HIPEC in the Department of Peritoneal Cancer Surgery, Beijing Shijitan Hospital, Capital Medical University from 2007 January to 2020 December were collected and subjected to Cox proportional regression analysis. All included patients had been diagnosed with peritoneal metastases from colorectal cancer and had no detectable distant metastases to other sites. Patients who had undergone emergency surgery because of obstruction or bleeding, or had other malignant diseases, or could not tolerate treatment because of severe comorbidities of the heart, lungs, liver or kidneys, or had been lost to follow-up, were excluded. Factors studied included: (1) basic clinicopathological characteristics; (2) details of CRS+HIPEC procedures; (3) overall survival rates; and (4) independent factors that influenced overall survival; the aim being to identify independent prognostic factors and use them to construct and validate a nomogram. The evaluation criteria used in this study were as follows. (1) Karnofsky Performance Scale (KPS) scores were used to quantitatively assess the quality of life of the study patients. The lower the score, the worse the patient's condition. (2) A peritoneal cancer index (PCI) was calculated by dividing the abdominal cavity into 13 regions, the highest score for each region being three points. The lower the score, the greater is the value of treatment. (3) Completeness of cytoreduction score (CC), where CC-0 and CC-1 denote complete eradication of tumor cells and CC-2 and CC-3 incomplete reduction of tumor cells. (4) To validate and evaluate the nomogram model, the internal validation cohort was bootstrapped 1000 times from the original data. The accuracy of prediction of the nomogram was evaluated with the consistency coefficient (C-index), and a C-index of 0.70-0.90 suggest that prediction by the model was accurate. Calibration curves were constructed to assess the conformity of predictions: the closer the predicted risk to the standard curve, the better the conformity. Results: The study cohort comprised 240 patients with peritoneal metastases from colorectal cancer who had undergone CRS+HIPEC. There were 104 women and 136 men of median age 52 years (10-79 years) and with a median preoperative KPS score of 90 points. There were 116 patients (48.3%) with PCI≤20 and 124 (51.7%) with PCI>20. Preoperative tumor markers were abnormal in 175 patients (72.9%) and normal in 38 (15.8%). HIPEC lasted 30 minutes in seven patients (2.9%), 60 minutes in 190 (79.2%), 90 minutes in 37 (15.4%), and 120 minutes in six (2.5%). There were 142 patients (59.2%) with CC scores 0-1 and 98 (40.8%) with CC scores 2-3. The incidence of Grade III to V adverse events was 21.7% (52/240). The median follow-up time is 15.3 (0.4-128.7) months. The median overall survival was 18.7 months, and the 1-, 3- and 5-year overall survival rates were 65.8%, 37.2% and 25.7%, respectively. Multivariate analysis showed that KPS score, preoperative tumor markers, CC score, and duration of HIPEC were independent prognostic factors. In the nomogram constructed with the above four variables, the predicted and actual values in the calibration curves for 1, 2 and 3-year survival rates were in good agreement, the C-index being 0.70 (95% CI: 0.65-0.75). Conclusions: Our nomogram, which was constructed with KPS score, preoperative tumor markers, CC score, and duration of HIPEC, accurately predicts the survival probability of patients with peritoneal metastases from colorectal cancer treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

ABSTRACT

Objectives: To evaluate the positive rate of left posterior lymph nodes of the superior mesenteric artery (14cd-LN) in patients undergoing pancreaticoduodenectomy for pancreatic head carcinoma,to analyze the impact of 14cd-LN dissection on lymph node staging and tumor TNM staging. Methods: The clinical and pathological data of 103 consecutive patients with pancreatic cancer who underwent pancreaticoduodenectomy at Pancreatic Center,the First Affiliated Hospital of Nanjing Medical University from January to December 2022 were analyzed,retrospectively. There were 69 males and 34 females,with an age(M (IQR))of 63.0 (14.0) years (range:48.0 to 86.0 years). The χ2 test and Fisher's exact probability method was used for comparison of the count data between the groups,respectively. The rank sum test was used for comparison of the measurement data between groups. Univariate and multivariate Logistic regression analyzes were used for the analysis of risk factors. Results: All 103 patients underwent pancreaticoduodenectomy successfully using the left-sided uncinate process and the artery first approach. Pathological examination showed pancreatic ductal adenocarcinoma in all cases. The location of the tumors was the pancreatic head in 40 cases,pancreatic head-uncinate in 45 cases,and pancreatic head-neck in 18 cases. Of the 103 patients,38 cases had moderately differentiated tumor and 65 cases had poorly differentiated tumor. The diameter of the lesions was 3.2 (0.8) cm (range:1.7 to 6.5 cm),the number of lymph nodes harvested was 25 (10) (range:11 to 53),and the number of positive lymph nodes was 1 (3) (range:0 to 40). The lymph node stage was stage N0 in 35 cases (34.0%),stage N1 in 43 cases (41.7%),and stage N2 in 25 cases (24.3%). TNM staging was stage ⅠA in 5 cases (4.9%),stage ⅠB in 19 cases (18.4%),stage ⅡA in 2 cases (1.9%),stage ⅡB in 38 cases (36.9%),stage Ⅲ in 38 cases (36.9%),and stage Ⅳ in 1 case (1.0%). In 103 patients with pancreatic head cancer,the overall positivity rate for 14cd-LN was 31.1% (32/103),and the positive rates for 14c-LN and 14d-LN were 21.4% (22/103) and 18.4% (19/103),respectively. 14cd-LN dissection increased the number of lymph nodes (P<0.01) and positive lymph nodes (P<0.01). As a result of the 14cd-LN dissection,the lymph node stage was changed in 6 patients,including 5 patients changed from N0 to N1 and 1 patient changed from N1 to N2. Similarly,the TNM stage was changed in 5 patients,including 2 patients changed from stage ⅠB to ⅡB,2 patients changed from stage ⅡA to ⅡB,and 1 patient changed from stage ⅡB to Ⅲ. Tumors located in the pancreatic head-uncinate (OR=3.43,95%CI:1.08 to 10.93,P=0.037) and the positivity of 7,8,9,12 LN (OR=5.45,95%CI:1.45 to 20.44,P=0.012) were independent risk factors for 14c-LN metastasis; while tumors with diameter >3 cm (OR=3.93,95%CI:1.08 to 14.33,P=0.038) and the positivity of 7,8,9,12 LN (OR=11.09,95%CI:2.69 to 45.80,P=0.001) were independent risk factors for 14d-LN metastasis. Conclusion: Due to its high positive rate in pancreatic head cancer,dissection of 14cd-LN during pancreaticoduodenectomy should be recommended,which can increase the number of lymph nodes harvested,provide a more accurate lymph node staging and TNM staging.

ABSTRACT

BackgroundAssisted reproductive technology is increasingly mature and widely used in clinic. As more and more newborns are born with assisted reproductive technology, the health problems of these newborns also need more attention. ObjectiveTo investigate the effects of assisted reproductive technology on newborn physique and autistic behavior, and to raise the attention of autistic behavior of assisted reproductive children. MethodsFrom the medical record information system, 588 assisted reproduction newborns (assisted reproduction group) born in the obstetrics department of Chaohu Hospital of Anhui Medical University from August 2018 to August 2019 were selected as the study objects. From the medical records information system, 600 newborns born naturally in the obstetrics department in the same period of time were selected as the control group. The basic information of all newborns was collected, including the mother's age and years of education, sex, gestational age, birth weight and birth length, and they were assessed by the Clancy Autism Behavior Scale (CABS) at 3 years of follow-up. ResultsThe educational years of mothers in assisted reproduction group were longer than those in control group [(12.04±1.96) years vs. (11.34±2.90) years, t=-4.887, P<0.01], gestational age and birth weight of assisted reproduction group were lower than those of control group [(38.68±2.56) weeks vs. (39.53±2.91) weeks, t=5.315, P<0.01; (3 273.27±720.39) g vs. (3 158.29±701.74) g, t=2.792, P<0.05]. There was no significant difference in birth length between the two groups [(49.97±5.94) cm vs. (50.07±6.08) cm, t=-0.287, P>0.05]. At the age of three, the weight and height of the assisted reproduction group were both lower than those of the control group [(16.16±2.53)kg vs.(16.96±1.67)kg, t=6.393, P<0.01, (95.81±4.50)cm vs.(97.47±7.49)cm, t=4.626, P<0.01]. Respectively, 6 (1.00%) and 15 (2.55%) children with autism were detected in the control group and assisted reproduction group, and the difference was statistically significant (χ2=4.113, P<0.05). ConclusionAssisted reproductive technology may affect the physical and neurological development of children.

ABSTRACT

@#Objective     To compare the clinical effects of coronary artery bypass grafting (CABG) via the left anterior small thoracotomy (LAST) versus lower-end sternal splitting (LESS) approach in the treatment of coronary heart disease. Methods     The patients who underwent LAST CABG in Tianjin Chest Hospital from October 2015 to December 2020 were allocated to an observation group (LAST group), and the patients who underwent LESS CABG at the same period were allocated to a LESS group. Propensity score matching method was applied with a ratio of 1∶1. The baseline data, perioperative data and grafts data were compared between the two groups after matching. Results     Before matching, there were 110 patients in the LAST group, and 206 patients in the LESS group. After matching, there were 110 patients in each group. In the LAST group, there were 83 males and 27 females with an average age of 60.6±8.3 years. In the LESS group, there were 80 males and 30 females with an average age of 61.0±9.6 years. There was no statistical difference in baseline data between the two groups after matching (P>0.05). The hospital stay time (t=2.255, P=0.025) and ventilator using time (t=−2.229, P=0.027) in the LAST group were significantly shorter than those in the LESS group. There were no statistical differences between the two groups in the postoperative hospital stay time, ICU stay time, postoperative left ventricular ejection fraction, postoperative left ventricular end-diastolic diameter, average number of grafts, secondary intubation, secondary thoracotomy, postoperative wound infection, sternal complications, postoperative atrial fibrillation, postoperative pulmonary infection or main adverse cardiovascular and cerebrovascular events (P>0.05). There was no statistical difference in the distribution of target vessels in the anterior descending branch, diagonal branch or posterior descending branch between the two groups (P>0.05). The grafts of the LAST group were significantly more than those of the LESS group in the area of obtuse marginal branch and posterior ventricular branch, and the grafts of the LESS group were significantly more than those of the LAST group in the area of right coronary artery (P<0.05). Post-operative computerized tomography angiography indicated that 1 patient in the LAST group had obtuse marginal branch vein bridge vessel occlusion, and the bridge vessels in the other patients were unobstructed. Conclusion     Minimally invasive CABG via both LAST and LESS approaches is safe and effective. LAST approach can achieve complete revascularization for multi-vessel lesions, and it is safe and reliable, with the advantages of less trauma and aesthetic appearance. However, it requires a certain learning curve of surgical techniques and certain surgical indications.

ABSTRACT

Objective:To investigate the clinical efficacy and precautions of O-arm combined with navigation-assisted steotomy and hemivertebra resection for congenital cervicothoracic hemivertebra.Methods:From February 2016 to October 2020, the clinical data of 12 patients with cervicothoracic hemivertebra admitted in Henan Provincial People's Hospital were retrospectively analyzed, including 5 males and 7 females, aged 9.4±2.6 years (range, 4-15 years). Intraoperative neural monitoring system was used to ensure the safety of surgical correction process and O-arm navigation system assisted the implantation of pedicle screws,hemivertebra resection, and scoliosis deformity correction. Postoperative CT was used to evaluate the accuracy of screw placement, and routine preoperative and postoperative X-ray films of the full-length spine in standing position were taken to measure the coronal and sagittal Cobb angles. The correction rate of scoliosis and kyphosis, internal fixation, shoulder height difference and bone graft fusion were calculated at the final follow-up.Results:A total of 108 pedicle screws were inserted in 12 patients, and the screw placement accuracy rate was 96.3% (104/108). The follow-up time was 37.9±10.2 months (range, 24-61 months). The number of fused segments was 5.4±1.1 (range, 4-7). One week after surgery, the correction rate of Cobb angle was 78.5%±3.2% for scoliosis and 70.1%±5.4% for kyphosis. There were statistically significant differences in side and kyphosis Angle and Scoliosis Research Society (SRS)-22 score between preoperative and 1 week after surgery ( P<0.05). There was no significant difference between the operation and the last follow-up ( P>0.05). At the last follow-up, all the 12 patients achieved gradeⅠ fusion. SI was 2.4±0.8 cm before operation, 1.0±0.6 cm at 1 week after operation, and 0.7±0.5 cm at last follow-up, and the difference was statistically significant ( F=38.30, P<0.001). No pseudojoint formation, significant loss of correction Angle, or rupture of internal fixation relaxant occurred during the operation or during follow-up. Conclusion:O-arm combined with navigation-assisted steotomy and hemivertebra resection for the treatment of congenital cervicothoracic hemivertebra has the advantages of good orthopedic effect, reduced radiation exposure and fewer complications, and accurate pedicle screw implantation and hemivertebra resection.

ABSTRACT

Objective:To investigate the clinical efficacy of satellite rod revision surgery via a combined anterior and posterior approach for rod fracture after posterior vertebral column resection (PVCR) in patients with severe thoracolumbar kyphosis.Methods:A retrospective case series study was conducted on the clinical data of 11 patients with rod fracture after PVCR for severe thoracolumbar kyphosis, who were treated in Henan Provincial People′s Hospital from January 2013 to January 2021. There were 6 males and 5 females, with the age range of 21-62 years [(35.4±13.0)years]. Among them, 4 patients had traumatic kyphosis, 4 presented congenital kyphosis and 3 showed tuberculous kyphosis. All the patients had obvious low back pain. According to the American Spinal Injury Association (ASIA) score, 2 patients were found with grade C, 2 with grade D and 7 with grade E. All the patients underwent revision surgery for internal fixation using satellite rod via a combined anterior and posterior approach. The operation time, intraoperative blood loss and postoperative hospital stay were recorded. The imaging parameters such as kyphosis Cobb angle, scoliosis Cobb angle, distance between C 7 plumb line and central sacral vertical line (C 7-CSVL), and distance between C 7 plumb line and sagittal vertical axis (SVA) were measured preoperatively, at 1 week postoperatively and at latest follow-up. At the same time, the visual analogue scale (VAS), Oswestry dysfunction index (ODI), and simplified Chinese version of the scoliosis research society-22 (SRS-22) questionnaire were used to evaluate the clinical efficacy. At the latest follow-up, the osteotomy fusion was evaluated by Suk criterion and ASIA score was used to evaluate the recovery of neurological function. The complications were also recorded for the patients. Results:All the patients were followed up for 24-84 months [(47.5±16.2)months]. The operation time was 100-220 minutes [(149.4±37.6)minutes], with the intraoperative blood loss of 150-350 ml [(246.3±64.6)ml] and the postoperative hospital stay of 5-8 days [(6.1±1.1)days]. The kyphosis Cobb angles [(18.5±3.2)° and (19.3±2.9)°] and the scoliosis Cobb angles [(11.8±2.2)°, (11.1±2.2)°] at 1 week post-operation and at the latest follow-up were all improved significantly compared with the preoperative ones [(60.4±6.3)°, (21.7±5.5)°] (all P<0.01), with the average correction rates being 69.4% and 45.6%, respectively, with no significant differences between 1 week post-operation and latest follow-up (all P>0.05). The C 7-CSVL was reduced from preoperative (21.2±4.3)mm to (15.7±2.4)mm at 1 week post-operation, and to (15.9±2.2)mm at the latest follow-up (all P<0.01). The SVA was improved from preoperative (51.0±6.8)mm to (16.6±3.6)mm at 1 week post-operation, and to (15.3±3.9)mm at the latest follow-up (all P<0.01). There were no significant differences in C 7-CSVL or SVA at 1 week post-operation or at the latest follow-up (all P>0.05). The VAS [(2.5±0.9)points, (1.9±0.9)points], ODI (20.1±5.4, 18.4±5.2) and SRS-22 [(83.4±5.8)points, (85.0±4.1)points] at 1 week post-operation and at the latest follow-up were significantly improved compared with the preoperative ones [(6.0±1.4)points, 57.2±8.7, (62.0±9.1)points] (all P<0.01), but no significant differences were found between 1 week post-operation and latest follow-up (all P>0.05). At the latest follow-up, the bone grafts achieved osseous fusion in all the patients, and the ASIA grade was improved from grade C to grade D in 2 patients and from grade D to grade E in 2 patients. No complications such as serious neurological or vascular injury occurred during perioperative period. No pseudoarthrosis formation, internal fixation loosening or fracture occurred during follow-up. Conclusion:Satellite rod revision surgery via a combined anterior and posterior approach for rod fracture after PVCR in patients with severe thoracolumbar kyphosis has the advantages of less trauma and faster convalescence, excellent results of deformity correction, significant pain relief, functional improvement, and fewer complications.

ABSTRACT

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.

ABSTRACT

Objective:To study the diagnostic value of the artificial intelligence (AI) diagnostic system, ACR TI-RADS classification and AI+ ACR TI-RADS combined diagnostic performance in benign and malignant thyroid nodules and its guiding significance for surgical treatment.Methods:From Nov. 1, 2021, to Feb. 26, 2022, 349 patients with 605 thyroid nodules who received surgical treatment in Department of Thyroid (Hernia) Surgery, Department of General Surgery, the First Medical Center of the PLA General Hospital, were selected. There were 95 males and 254 females, male: female=1:2.67, aged 16-78 years, and the nodule diameter was 0.2-5.6 cm. SPSS 26.0 and R studio software were used for data processing. AI diagnostic system, ACR TI-RADS grading and AI+ ACR TI-RADS combined diagnostic efficacy were statistically analyzed, respectively. ROC curve analysis was performed in parallel.Results:The AUC value of AI+ ACR TI-RADS combined diagnosis was 0.900, greater than 0.857 of AI diagnostic system and 0.788 of ACR TI-RADS, and the difference was statistically significant ( Z= 7.631, both P<0.001) . The sensitivity of the combined diagnosis was 95.32%, the specificity was 84.61%, the accuracy was 92.56%, the positive predictive value was 94.69%, the negative predictive value was 86.27%, the missed diagnosis rate was 4.68%, and the misdiagnosis rate was 15.38%, which were better than the other two diagnostic methods. With an excellent coincidence rate with postoperative pathological results ( Kappa=0.804, P<0.001) . The accuracy of combined diagnosis in identifying the maximum diameter of different tumors was 89.58% for d≤0.5 cm, 96.09% for 0.5<d≤1.0 cm, 95.45% for 1.0<d≤2.0 cm, 87.88% for 2.0<d≤4.0 cm, and 85.71% for d>4.0 cm, better than the other two diagnostic methods. Conclusions:The combined application of AI+ACR TI-RADS has a certain primary screening value in evaluating thyroid nodule properties. The combined diagnosis of the two can more effectively determine the benign and malignant thyroid nodules.

ABSTRACT

Objective To measure the prevalence of mental health symptoms and identify the associated factors among college students at the beginning of coronavirus disease 2019(COVID-19)outbreak in China. Methods We carried out a multi-center cross-sectional study via snowball sampling and convenience sampling of the college students in different areas of China.The rates of self-reported depression,anxiety,and stress and post-traumatic stress disorder(PTSD)were assessed via the 21-item Depression-Anxiety-Stress Scale(DASS-21)and the 6-item Impact of Event Scale-Revised(IES-6),respectively.Covariates included sociodemographic characteristics,health-related data,and information of the social environment.Data pertaining to mental health service seeking were also collected.Multivariate Logistic regression analyses were performed to identify the risk factors. Results A total of 3641 valid questionnaires were collected from college students.At the beginning of the COVID-19 outbreak,535(14.69%)students had negative emotions,among which 402(11.04%),381(10.49%),and 171(4.90%)students had the symptoms of depression,anxiety,and stress,respectively.Meanwhile,1245(34.19%)college students had PTSD.Among the risk factors identified,male gender was associated with a lower likelihood of reporting depression symptoms(AOR=0.755,P=0.037],and medical students were at higher risk of depression and stress symptoms than liberal arts students(AOR=1.497,P=0.003;AOR=1.494,P=0.045).Family support was associated with lower risks of negative emotions and PTSD in college students(AOR=0.918,P<0.001;AOR=0.913,P<0.001;AOR=0.899,P<0.001;AOR=0.971,P=0.021). Conclusions College students were more sensitive to public health emergencies,and the incidence of negative emotions and PTSD was significantly higher than that before the outbreak of COVID-19.More attention should be paid to female college students who were more likely to develop negative emotions.We should strengthen positive and proper propaganda via mass media and help college students understand the situation and impact of COVID-19.Furthermore,we should enhance family support for college students.The government and relevant agencies need to provide appropriate mental health services to the students under similar circumstances to avoid the deterioration of their mental well-being.
