Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To investigate the predictive value of clinical factor model, deep learning model based on baseline plain CT images, and combination of both for predicting hematoma expansion in cerebral hemorrhage.Methods:The study was cross-sectional. Totally 471 cerebral hemorrhage patients who were firstly diagnosed in the Second Affiliated Hospital of Soochow University from January 2017 to December 2021 were collected retrospectively. These patients were randomly divided into a training dataset ( n=330) and a validation dataset ( n=141) at a ratio of 7∶3 by using the random function. All patients underwent two noncontrast CT examinations within 24 h and an increase in hematoma volume of >33% or an absolute increase in hematoma volume of >6 ml was considered hematoma enlargement. According to the presence or absence of hematoma enlargement, all patients were divided into hematoma enlargement group and hematoma non-enlargement group.Two-sample t test, Mann-Whitney U test or χ2 test were used for univariate analysis. The factors with statistically significant differences were included in multivariate logistic regression analysis, and independent influences related to hematoma enlargement were screened out to establish a clinical factor model. ITK-SNAP software was applied to manually label and segment the cerebral hemorrhage lesions on plain CT images to train and build a deep learning model based on ResNet50 architecture. A combination model for predicting hematoma expansion in cerebral hemorrhage was established by combining independent clinical influences with deep learning scores. The value of the clinical factor model, the deep learning model, and the combination model for predicting hematoma expansion in cerebral hemorrhage was evaluated using receiver operating characteristic (ROC) curves and decision curves in the training and validation datasets. Results:Among 471 cerebral hemorrhage patients, 136 cases were in the hematoma enlargement group and 335 cases were in the hematoma non-enlargement group. Regression analyses showed that male ( OR=1.790, 95% CI 1.136-2.819, P=0.012), time of occurrence ( OR=0.812, 95% CI 0.702-0.939, P=0.005), history of oral anticoagulants ( OR=2.157, 95% CI 1.100-4.229, P=0.025), admission Glasgow Coma Scale score ( OR=0.866, 95% CI 0.807-0.929, P<0.001) and red blood cell distribution width ( OR=1.045, 95% CI 1.010-1.081, P=0.011) were the independent factors for predicting hematoma expansion in cerebral hemorrhage. ROC curve analysis showed that in the training dataset, the area under the curve (AUC) of clinical factor model, deep learning model and combination model were 0.688 (95% CI 0.635-0.738), 0.695 (95% CI 0.642-0.744) and 0.747 (95% CI 0.697-0.793) respectively. The AUC of the combination model was better than that of the clinical model ( Z=0.54, P=0.011) and the deep learning model ( Z=2.44, P=0.015). In the validation dataset, the AUC of clinical factor model, deep learning model and combination model were 0.687 (95% CI 0.604-0.763), 0.683 (95% CI 0.599-0.759) and 0.736 (95% CI 0.655-0.806) respectively, with no statistical significance. Decision curves showed that the combination model had the highest net benefit rate and strong clinical practicability. Conclusions:Both the deep learning model and the clinical factor model established in this study have some predictive value for hematoma expansion in cerebral hemorrhage; the combination model established by the two together has the highest predictive value and can be applied to predict hematoma expansion.

Objective:To investigate the effect of biofeedback combined with pelvic floor training on stress urinary incontinence in elderly men.Methods:This study was prospective and Patients with urinary incontinence after radical prostatectomy from China Rehabilitation Research Center were enrolled. The patients who could not complete or refused the study, had a history of other urinary diseases, and central nervous system diseases were excluded. Patients were divided by random number table method into 3 groups. They were Kegel training group (Group A)which underwent anus contraction training with each contraction for 5 seconds and a rest interval of 2 seconds. Biofeedback combined with Kegel training group (Group B), which was biofeedback combined with anus contraction training and the biofeedback combined Pilates group (Group C) which received the biofeedback combined Pilates training. In group B and group C, patients were placed in the right lateral position and the surface electrode of the rectal probe was inserted into the anus. The reference electrode was fixed at the adductor muscle of the right thigh. The patient is asked to squeeze the electrode as hard as possible by constricting the anus so that the electromyographic signals produced by constricting the anus are synchronized with those on the computer screen. In the electrical stimulation stage of biofeedback therapy, rhomboid waves with current intensity of 30-50 Hz and pulse width of 300μs were used, and the electrical stimulation intensity was determined by the subtle muscle contraction visible. Each of the three training sessions lasted 45 minutes a day for 8 weeks. 1 hour pad test, daily incontinence times, (International Incontinence Counseling Questionnaire, ICIQ), and Oxford Score Scale were recorded every weekend. The 1-hour pad test, the number of incontinent episodes, ICIQ, Oxford Score scale before and after treatment were compared among the three groups, as well as the differences between the groups.Results:There were no significant differences in age, height, weight, history of diabetes or hypertension before treatment, time from postoperative to training, operation method, retention of nerve tract during surgery, Gleason score, 1-hour pad test, the number of episodes of incontinence, ICIQ and Oxford Grading Scale among the 3 groups. The 1-hour pad test results of group A, B and C were (37.4±7.2), (22.2±4.7) and (18.3±2.4) g, respectively, with statistical significance among the three groups ( P<0.01), and the difference between the three groups and before treatment was statistically significant ( P<0.01).

Objective:To identify the transmission relationship between HIV infection cases the non-marital non-commercial heterosexual contact in Zhejiang Province.Methods:When HIV positive was informed during January 2020 to January 2022, the staff conducted an epidemiological investigation to collect cases information on sociodemographic characteristics, mobility information, past HIV testing history, high-risk sexual behaviors, sexual partners, and etcetera. At the same time, 6-8 ml of blood from the new diagnosis of people infected with HIV before antiviral treatment was collected to separate the bleeding plasma. pol gene was amplified by nucleic acid extraction and PCR, sequenced by Sequencer 5.0 software, and Cytoscape 3.6.0 software was used to draw HIV molecular transmission network. Results:From January 2020 to January 2022, 88 HIV infected individuals were found in Pujiang County, of which 74 were transmitted through heterosexual transmission, of which 31 were infected through non-marital non-commercial heterosexual contact. Preliminary case studies have found that three female cases have engaged in unprotected non-marital non-commercial heterosexual contact with one male case. Among the 4 infected individuals, 2 of their spouses tested positive for HIV antibodies. Molecular transmission network monitoring was carried out on 65 newly diagnosed cases of heterosexual transmission with acquired sequences, forming 9 transmission clusters. The largest cluster contained 10 cases. A total of 11 HIV-infected individuals were involved in this HIV cluster epidemic. They were 3 males and 8 females, all over 50 years old and were farmers or rural housewives. They were traced to 7 sexual partners (6 negatives of HIV, 1 undetected). Among the 18 respondents' sexual social network relationships, there were 6 couples, 8 permanent partners, and 3 temporary partners. Among 11 HIV infected individuals, there were 9 cases of non-marital non-commercial heterosexual transmission and 2 cases of intramarital transmission. The epidemiological association between 7 non-married non-commercial heterosexual partners and case 2 (56-year-old male farmer), 3 cases confirmed by epidemiological investigation and molecular transmission cluster results, 3 cases confirmed by molecular transmission cluster and epidemiological investigation results, and 1 case confirmed by epidemiological investigation results.Conclusions:The transmission mode of this cluster epidemic was to spread HIV through heterosexual sex with a male case as the core, then cause the transmission within marriage and between fixed sexual partners. The combination of epidemiological investigation and molecular transmission network traceability survey supports the conclusion of this study.

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.

Objective:To investigate the long term outcome of artificial urinary sphincter implantation for patients with stress urinary incontinence.Methods:The data of 46 patients who underwent artificial urethral sphincter implantation in China Rehabilitation Research Center from April 2002 to April 2022 were retrospectively analyzed.The patients’ age ranged from 19-80 years old (median 45.6 years). There were 45 males and 1 female. The history of illness was 8 months to 33 years. The patients category were urethral injuries associated urinary incontinence ( n=24), neurogenic urinary incontinence ( n=9) and post-prostatectomy incontinence ( n=13). Preoperative daily pad usage was 3.5±1.0. The impact of incontinence on the quality of life (QOL)measured by the visual analogue scale (VAS)was 7.1±1.2. All 46 patients underwent artificial urethral sphincter implantation, of which 20 patients were treated with anticholinergic drugs (5 cases) or urinary tract related surgery (urethral stenosis incision in 2 cases, sphincterectomy in 3 cases, urethral dilation in 5 cases, urethral calculus lithotripsy in 1 case, and augmentation cystoplasty in 4 cases) before artificial urethral sphincter implantation. Of the 45 male patients, 25 patients had the transperineal approach and 20 had the trans-scrotal approach. The female case had a trans-retropubic approach. Different cuffs size was used based on individual circumference of bulbar urethra (45 male cases: 4.5cm in 16 cases, 4.0cm in 29 cases; one female case: 8.0cm). Long-term surgical efficacy was evaluated. Assessments included postoperative urinary continence (socially continent: one pad per day or less; complete dry: wearing no pads), artificial urinary sphincter status and complications. The influences of patients of different etiologies, surgical approaches and cuff size on surgical results were compared. Results:The mean follow-up time was 7.1 years ranged from 6 months to 19 years. At the latest visit, 32 patients (69.6%) maintained the primary functional artificial urinary sphincter. Three patients (6.5%) had artificial urinary sphincter revisions and maintained continence with the new device. 11 patients (23.9%) removed the artificial urinary sphincter because of post-complications. Thirty-five patients were socially continent, of which 16 patients were totally dry, leading to the overall social continent rate as 76.1%(35/46). There was a significant reduction in pad usage to 1.2±0.6 diapers per day ( P<0.001). The impact of incontinence on the QOL measured by the VAS dropped to 2.6±1.9 ( P<0.001). The complication rate was 32.6%(15/46), including infections ( n=4), erosions ( n=5), mechanical failure ( n=3), dysurie ( n=2) and urethral atrophy ( n=1). There were no significant differences in social continent rate between patients with different etiologies[75.0%(18/24)vs. 66.7%(6/9) vs. 84.6%(11/13)], perioperative complications [37.5%(9/24)vs. 33.3%(3/9) vs. 23.1%(3/13)] and device re-intervention rate[37.5%(9/24) vs. 33.3%(3/9)vs. 15.4%(2/13)]. There were no statistically significant differences in postoperative complete dry rate [32%(8/25)vs. 40%(8/20), P=0.76] and postoperative device failure free rate [60%(15/25)vs. 80%(16/20), P=0.20] between trans-perineal group and trans-scrotal group. There was no statistically significant difference in postoperative social continent rate between 4.5cm cuff and 4.0 cuff[75%(12/16) vs. 65.5%(19/29), P=0.74]. Conclusions:Artificial urethral sphincter implantation is an effective treatment for stress urinary incontinence due to intrinsic sphincter deficiency. There was no difference in the continent rate and complication rate between patients of different etiologies, different surgical approaches and cuff size selection.

Objective:To explore the role of interleukin (IL)-9 and other T helper (Th) cell-related cytokines in the pathogenesis of acute anterior uveitis.Methods:A cross-sectional study was conducted.Thirty-six patients (36 eyes) with acute anterior uveitis who were treated at Gansu Provincial Hospital from May 2018 to May 2019 and 40 matched healthy subjects (40 eyes) who had no eye diseases or systemic diseases in the same period were enrolled as the acute anterior uveitis group and healthy control group, respectively.The disease severity of the subjects in the acute anterior uveitis group was graded and the subjects were divided into mild, moderate and severe groups according to the grading.Serum of all subjects was collected to determine the concentration of serum IL-9, IL-17, transforming growth factor-β 1 (TGF-β 1), interferon-γ (IFN-γ), IL-4, IL-35 and IL-22 by enzyme linked immunosorbent assay (ELISA) method.Spearman rank correlation analysis was used to evaluate the relationship between IL-9 concentration and other Th cell-related cytokines.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Gansu Provincial Hospital (No.2019-204). Written informed consent was obtained from each subject prior to any medical examination. Results:The serum levels of IL-9, IFN-γ, IL-4, TGF-β 1, IL-35 and IL-22 in the acute anterior uveitis group were significantly higher than those in the healthy control group, and the differences were statistically significant (all at P<0.05). There was no statistically significant difference in the concentration of IL-17 between the two groups ( U=704.500, P=0.872). The IL-9 concentration of patients with acute anterior uveitis in the mild, moderate and severe groups was 57.24 (47.47, 65.10), 71.68 (67.55, 78.91) and 114.01 (74.78, 139.30) ng/L, respectively, and the overall difference was statistically significant ( Z=8.766, P=0.012), and the IL-9 concentration of the mild group and the moderate group was significantly lower than that of the severe group (both at P<0.05). The concentration of IL-9 in the patients with acute anterior uveitis was positively correlated with the concentration of IL-17, TGF-β 1 and IL-35 ( rs=0.449, 0.517, 0.400; all at P<0.05), and no significant correlations were found between the concentration of IL-9 and the concentration of IFN-γ, IL-4 and IL-22 ( rs=0.293, 0.286, 0.316; all at P>0.05). Conclusions:IL-9 plays a role in promoting the immune inflammatory response in the occurrence and development of acute anterior uveitis, and it is closely related to Th17 and Treg cell-related cytokines (TGF-β 1, IL-35).
