The intestinal flora and gut barrier function are of great significance for gut function and human health. When the intestinal flora is disrupted and the gut barrier structure is disrupted, it can lead to bacterial translocation, endotoxin influx into the bloodstream, and the production of pro-inflammatory factors, leading to various tissue damage in the body. Tongfu method in TCM can affect the intestinal environment by regulating intestinal permeability and immune response, restoring normal intestinal movement, and regulating the structure and metabolites of intestinal flora, thereby maintaining intestinal homeostasis and body health. The research on regulating intestinal flora and improving intestinal barrier function by Tongfu method can provide reference for further research on the relationship between TCM and intestinal microecology, and provide ideas for clinical treatment.

【Objective】 To establish a risk model for predicting spontaneous rupture bleeding of renal angiomyolipoma (RAML) in order to better assess and deal with the risk. 【Methods】 The information of 436 RAML patients diagnosed during Jan.2018 and Dec.2022 was retrospectively analyzed.According to the inclusion and exclusion criteria, 216 patients were included and divided into the rupture bleeding group (n=35) and non-rupture bleeding group (n=181).The factors influencing spontaneous rupture bleeding were identified using univariate and multivariate analysis, and a nomogram was constructed accordingly with R language.The nomogram was evaluated using Calibration curve and area under the receiver operator characteristic curve (AUC). 【Results】 It was found that clinical manifestations, tumor diameter, tumor convexity, tumor blood supply, and tuberous sclerosis complex (TSC) were significantly correlated with rupture bleeding.The Calibration curve fitted well with the nomogram.The AUC was 0.956 (95%CI: 0.856-0.943), indicating that the nomogram had good statistical performance. 【Conclusion】 The model can effectively predict the risk of spontaneous rupture bleeding of renal angiomyolipoma.

Objective:To explore the prognostic predictive value of deep neural network (DNN) assisted myocardial contrast echocardiography (MCE) quantitative analysis of ST-elevated myocardial infarction (STEMI) patients after successful percutaneous coronary intervention(PCI).Methods:A retrospective analysis was performed in 97 STEMI patients with thrombolysis in myocardial infarction-3 flow in infarct vessel after primary PCI in Renmin Hospital of Wuhan University from June to November 2021. MCE was performed within 48 h after PCI. Patients were followed up to 120 days. The adverse events were defined as cardiac death, hospitalization for congestive heart failure, reinfarction, stroke and recurrent angina. The framework consisted of the U-net and hierarchical convolutional LSTMs. The plateau myocardial contrast intensity (A), micro-bubble rate constant (β), and microvascular blood flow (MBF) for all myocardial segments were obtained by the framework, and then underwent variability analysis. Patients were divided into low MBF group and high MBF group based on MBF values, the baseline characteristics and adverse events were compared between the two groups. Other variables included biomarkers, ventricular wall motion analysis, MCE qualitative analysis, and left ventricular ejection fraction. The relationship between various variables and prognosis was investigated using Cox regression analysis. The ROC curve was plotted to evaluate the diagnostic efficacy of the models, and the diagnostic efficacy of the models was compared using the integrated discrimination improvement index (IDI).Results:The time-cost for processing all 3 810 frames from 97 patients was 377 s. 92.89% and 7.11% of the frames were evaluated by an experienced echocardiographer as "good segmentation" and "correction needed". The correlation coefficients of A, β, and MBF ranged from 0.97 to 0.99 for intra-observer and inter-observer variability. During follow-up, 20 patients met the adverse events. Multivariate Cox regression analysis showed that for each increase of 1 IU/s in MBF of the infarct-related artery territory, the risk of adverse events decreased by 6% ( HR 0.94, 95% CI =0.91-0.98). There was a 4.5-fold increased risk of adverse events in the low MBF group ( HR 5.50, 95% CI=1.55-19.49). After incorporating DNN-assisted MCE quantitative analysis into qualitative analysis, the IDI for prognostic prediction was 15% (AUC 0.86, sensitivity 0.78, specificity 0.73). Conclusions:MBF of the area supplied by infarct-related artery after STEMI-PCI is an independent protective factor for short-term prognosis. The DNN-assisted MCE quantitative analysis is an objective, efficient, and reproducible method to evaluate microvascular perfusion. Assessment of culprit-MBF after PCI in STEMI patients adds independent short-term prognostic information over qualitative analysis.It has the potential to be a valuable tool for risk stratification and clinical follow-up.

Transcranial direct current stimulation (tDCS) is a well-tolerated, safe and noninvasive physical brain stimulation method, which has been widely used in the treatment of some common mental disorders and neurological diseases and has achieved certain clinical effects. It is necessary to develop expert consensus on clinical treatment to improve the use norms in related fields. According to the clinical research published before August 2021 and the method of evidence-based medicine, we published an expert consensus on tDCS in the treatment of depressive disorders, schizophrenia, substance use-related disorders, obsessive-compulsive disorder, attention deficit hyperactivity disorder, autism, anxiety disorders, post-traumatic stress disorder, sleep disorders, pain, Parkinson′s disease, stroke, and epilepsy. The consensus also introduced the safety and efficacy of the clinical use of tDCS, and standardized the treatment process and operation technology, aiming to provide guidance for the clinical application of tDCS and promote the standardized development of this treatment technology in the future.

In this study, a new ileal orthotopic bladder (Urumqi Bladder) modified by our center based on the ileal "W" type orthotopic bladder and Studer bladder was used on 8 patients with invasive bladder cancer. All of patients were male and aged between 54 and 66 years. The history of disease ranged from 1 month to 3 years, including 5 patients with initial onset, 3 patients with ≥2 TURBT history. 6 patients had multiple tumors, tumor size from 0.5 cm to 2.5cm. There were 2 patients with single tumor. Preoperative PET-CT examination showed no distant metastasis and pelvic lymph node enlargement, no urinary tract hydronephrosis, and cystoscopy showed no suspected tumor in the urethra. Preoperative pathological results: high-grade invasive urothelial carcinoma was found in 6 cases and muscular invasive urothelial carcinoma in 2 cases. In 8 patients, 50cm ileum was taken from 15cm away from ileocecum after radical cystectomy, which was crimped clockwise inward from the right end into a nearly circular shape, with 10cm left at the left end. The remaining 40cm ileum was formed into 3 sections of about 13cm each, which were decanted to form a storage capsule. The last 10cm intestinal tube was crossed from the front of sigmoid colon. The end of intestine was anastomosed with the left ureter. The right ureter was anastomosed with the top of the right intestine pouch, and the urethra was anastomosed with the pouch to complete the diversion of urine flow. During 3-12 months of postoperative follow-up, 4 patients had short-term mild urinary incontinence. All had complete urinary control at 12 months. 1 patient still had mild left ureter reflux 12 months after surgery, and the other 7 patients had no ureter reflux. In this group of 8 patients, postoperative excretory cystography showed satisfactory effect of bladder voiding, residual, and bladder capacity. Follow-up review of chest CT, urinary CT and abdominal ultrasound showed no hydronephrosis, and no tumor recurrence or distant metastasis.

Objective? To explore the effects of single disease management in burns scar repair patients. Methods? From June 2015 to March 2018, we selected 68 burns scar repair patients of Shaanxi Provincial People's Hospital as subject by convenient sampling. All of the patients were divided into two groups according to admission time including control group (n=34, admitted from June 2015 to January 2017) and observation group (n=34, admitted from February 2017 to March 2018). Control group carried out routine nursing. Observation group received single disease management. The Vancouver Scar Scale (VSS) was used to assess the scar hyperplasia of patients between groups, and patient satisfaction as well as hospital stay of patients between two groups were compared. Results? At admission, there was no statistical difference in the score of VSS of patients in two groups (P＞0.05). Six months after intervention, the colors, vessels distribution, thickness, softness and the total score of patients in observation group were lower than those in control group with statistical differences (P＜0.05). At discharge, the patient satisfaction of observation group was higher than that of control group with a statistical difference (P＜0.05);the hospital stay of patients in observation group was statistically lower than that in control group (P＜ 0.05). Conclusions? The application of single disease management in burns scar repair patients is conducive to improving patients' severity of scar, patient satisfaction and shortening the hospital stay, which is worthy of promotion and application.

Objective To investigate the prevalence of high-risk HPV subtypes in different pathological types of cervical cancer, and analyze the attribution of carcinogenic HPV subtypes in different pathological types. Methods A total of 1 541 patients with cervical cancer were treated between February 2009 and October 2016 in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. The median age at diagnosis was 49 years (ranged 20-82 years old). The numbers of patients with cervical cancer from North China, Northeast China, East China, Central China and other regions (including Northwest, Southwest and South China) were 961, 244, 175, 87 and 74 cases, respectively. Pathological types: 1 337 cases of squamous cell carcinoma (SCC), 87 usual adenocarcinoma (ADC), 23 adenosquamous carcinoma (ASC), 20 mucinous carcinoma (MC), 19 clear cell carcinoma (CCC), 12 endometrioid carcinoma (EC), 25 neuroendocrine carcinoma (NEC), 9 serous carcinoma (SC), 5 villous adenocarcinoma (VADC) and 4 minimal deviation adenocarcinoma (MDAC). The prevalence of high-risk HPV in different regions, age groups at diagnosis and pathological types in cervical cancer were analyzed. The attribution of 13 high-risk HPV subtypes in different pathological types of cervical cancer based on proportional attribution method, and the attribution of high-risk HPV subtypes prevented by 9-valent HPV vaccine in SCC and ADC were calculated. Results (1) The prevalence of high-risk HPV in 1 541 patients with cervical cancer was 86.6% (1 335/1 541). The multiple high-risk HPV infection rate in patients with SCC ≥60 years old (23.0%, 37/161) was significantly higher than those in patients aged 45-59 years old and≤44 years old [11.4% (85/747) vs 11.7% (50/429), P<0.01], and the high-risk HPV infection rates of patients with cervical cancer in North China, Northeast China, East China, Central China and other regions were respectively 86.8% (834/961), 87.7% (214/244), 83.4% (146/175), 83.9% (73/87) and 91.9% (68/74). SCC (86.8%, 1 337/1 541) and ADC (5.6%, 87/1 541) were the most common pathological types in cervical cancer. The high-risk HPV prevalence of SCC, ADC, ASC, MC, NEC and VADC were 90.1% (1 205/1 337), 74.7% (65/87), 87.0% (20/23), 65.0% (13/20), 72.0% (18/25) and 5/5 respectively. The high-risk HPV infection rates of SC, EC, CCC and MDAC were 4/9, 3/12, 2/19 and 0/4 respectively. (2) According to proportional attribution, HPV 16 (69.5%), HPV 18 (5.6%), HPV 58 (2.2%), HPV 31 (1.9%), HPV 52 (1.4%) and HPV 33 (1.3%) were the six common high-risk HPV subtypes in SCC. While, HPV 18 (44.1%), HPV 16 (20.5%), HPV 52 (2.3%), HPV 58 (1.2%) and HPV 51 (1.2%) were the main carcinogenic subtypes in ADC. The main carcinogenic high-risk HPV subtypes of ASC, NEC and MC were HPV 18 and HPV 16. The total attribution of HPV 16, 18, 31, 33, 45, 52 and 58 prevented by 9-valent HPV vaccine in SCC and ADC were 82.6% and 68.1% respectively; the attribution of HPV 45 in SCC and ADC were only 0.8% and 0. Conclusions SCC and ADC are the main pathological types in cervical cancer. SCC, ADC, ASC, MC, NEC and VADC are closely related to high-risk HPV infection. HPV 16 is the main carcinogenic genotypes of SCC. HPV 18 maybe play an important role in the pathogenesis of ADC.
