Objective: To investigate the influencing factors of overactive bladder (OAB) in college freshmen and the impacts of OAB on their mental health, quality of life and social interaction. Methods: An epidemiological questionnaire survey was conducted in an anonymous manner on the prevalence of OAB among 5300 freshmen aged 17 to 22 years enrolled in the 2023—2024 academic year in Xinxiang Medical University and Sanquan College of Xinxiang Medical University.The questionnaire included questions on basic information, history of urinary tract infection, constipation, smoking, history of alcohol consumption, history of coffee/strong tea drinking, history of carbonated beverage drinking, redundant prepuce, phimosis, holding urine, chronic insomnia, self-rating anxiety scale (SAS), quality of life score (QoL), and social avoidance and distress scale (SADS).The influencing factors of OAB were analyzed with multivariate logistic regression analysis.The subjects were grouped according to whether they had OAB, and the differences in SAS, QoL and SADS between the OAB group and non-OAB group were compared.The impacts of OAB on the anxiety level, quality of life, and social interaction were analyzed with multiple linear regression analysis. Results: The overall prevalence rate of OAB was 4.9% (244/5018).Multivariate logistic regression analysis showed that the history of urinary tract infection (OR=0.177), constipation (OR=0.636), smoking (OR=0.582), alcohol consumption (OR=0.685), coffee/strong tea drinking (OR=0.387), carbonated beverage drinking (OR=0.631), redundant prepuce (OR=0.673), phimosis (OR=0.311), urine holding (OR=0.593), and chronic insomnia (OR=0.256) were influencing factors for the occurrence of OAB (P＜0.05).The OAB group had higher SAS score [(41.18±6.54) vs. (38.61±6.36)], QoL score [(3.65±1.20) vs. (2.79±0.95)], social avoidance score [(6.25±1.86) vs. (5.86±1.51)], social distress score [(6.27±1.59) vs. (5.97±1.32)], and total SADS score [(12.51±2.35) vs. (11.84±2.01)] than the non-OAB group (P＜0.05).The results of multiple linear regression analysis showed that OAB could independently affect the scores of QoL, SAS, and SADS.The OAB group had higher scores of QoL, SAS, and SADS compared with the non-OAB group (P＜0.001). Conclusion: History of urinary tract infection, constipation, smoking, alcohol consumption, coffee/strong tea drinking, carbonated beverage drinking, redundant prepuce, phimosis, urine holding, and chronic insomnia are influencing factors for the occurrence of OAB in male college students.Moreover, OAB has negative impacts on their mental health, quality of life, and social interaction.

At present,the incidence of breast cancer has been the first in the world,and hormone receptor-positive(HR+)/human epidermal growth factor receptor 2-negative(HER2-)advanced breast cancer has seriously affected the prognosis of patients.In the past,the therapeutic drugs were mainly third-generation aromatase inhibitors(AI)and fulvestrant.In recent years,the era of endocrine therapy combined with cyclin-dependent kinase4/6(CDK4/6)inhibitors has begun.Different CDK4/6 inhibitors have different related adverse events,and they need to evaluate the physical condition of patients and develop a treatment plan,but neutropenia is prevalent.Everolimus,Alpelisib,and Chidamide are second-line therapeutic drugs.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

Background: Hepatic encephalopathy (HE) is one of the main causes of death in patients with end-stage liver disease. Early evaluation of the condition of patients with liver cirrhosis complicated with HE is the key for improving the prognosis. Aims: To investigate the effects of controlling nutritional status (CONUT) and CTP score on predicting the short term prognosis of liver cirrhosis patients complicated with HE. Methods: The clinical data of 168 liver cirrhosis patients complicated with HE initially diagnosed in Nantong Third People's Hospital from January 2018 to December 2021 were enrolled and analyzed retrospectively. HE patients were divided into survival group and death group. Cox regression analysis was used to evaluate the risk factors affecting the prognosis. A new prediction model was established, and ROC curve was used to evaluate the values of different models for short⁃term prognosis of HE patients. Survival was evaluated by Kaplan⁃Meier method. Results: Compared with survival group, ALT, AST, TBIL, INR, white blood cell count, neutrophil were significantly increased in death group (P<0.05), while ALB, total cholesterol, serum Na, fibrinogen, lymphocyte were significantly decreased (P<0.05). CONUT (OR=1.499, 95% CI: 1.092⁃2.057, P=0.012), CTP score (OR=1.474, 95% CI: 1.178⁃1.844, P=0.001) were independent risk factors for 90⁃day mortality in liver cirrhosis patients complicated with HE. AUC of CTP, CONUT and CONUT⁃CTP scoring models were 0.90, 0.94 and 0.95, respectively. Kaplan⁃Meier analysis showed that the survival rate in CONUT⁃CTP≥7.50 group was significantly lower than that in <7.50 group (P<0.000 1). Conclusions: CONUT⁃CTP score has good predictive value for the prognosis of liver cirrhosis patients complicated with HE, CONUT⁃CTP ≥7.50 indicates poor prognosis.

Objective:To analyze the trend of liver cancer morbidity and mortality among residents with household registration in certain District, 2017 to 2019.Methods:The crude morbidity and mortality rate of males and females in the whole population were calculated by using the relevant data from the certain District Cancer Registry and Report System and the Cause of Death Surveillance System. The standardized morbidity and mortality rate were calculated according to the age structure of 2000 National Demographic Census and Segi's world population, respectively. Trend in liver cancer morbidity and mortality were evaluated using percent change (PC), annual percentage change, and case-number-weighted annual percent change. Age-specific rates were used to analyze the epidemic trend of liver cancer with age.Results:The crude morbidity rate of liver cancer in the whole population (male and female) of the certain district from 2017 to 2019 were 18.86/100 000, 26.05/100 000 and 11.90/100 000 respectively, and the crude mortality rates were 21.20/100 000, 29.29/100 000 and 13.38/100 000 respectively. The crude morbidity and mortality rate of liver cancer among male showed a downward trend (PC=-16.77% and -20.15% respectively). The crude morbidity and mortality rate of liver cancer among female showed inconsistent changes; however, the crude morbidity rate showed a downward trend, and the crude mortality rate first increased and then decreased (PC=-19.42% and -0.30% respectively). Liver cancer morbidity and mortality rate in male after the age of 30 were increased with age. The two key points of accelerated growth were around the age of 65 and 75, and the peak of morbidity (130.78/100 000) and mortality (201.96/100 000) were after the age of 80. The morbidity and mortality rate were significantly lower in female than those of male aged 60; however, after the age of 65, the morbidity rate was increased rapidly and gradually approached as that of male. After the age of 80 (the peak morbidity and mortality were 104.40/100,000 and 132.87/100,000, respectively), male were about twice as high as those female aged between 75 and 79.Conclusion:Morbidity and mortality rate of liver cancer in the certain District showed an overall downward trend from 2017 to 2019, but it increased with age, and the disease burden was relatively high among the elderly population. Liver cancer mostly occurred in male, so the prevention and control of liver cancer epidemics in middle-aged and elderly should be actively monitored.

Objective:To explore the role of macrophages in non-alcoholic steatohepatitis (NASH) in order to provide directions for the therapeutic target of metabolic liver disease.Methods:Twenty C57BL/6 wild-type male mice at 6-8 weeks were randomly divided into two groups: 5 in the control group, methionine-and choline-deficient diet (MCD); 15 in the experimental group, MCD diet + intraperitoneal injection of disodium chlorophosphonate liposomes (to clear macrophages). Mice were fed for 4 weeks to establish NASH model. Blood, liver and spleen were collected to analyze the body mass index, liver index, spleen index, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Non-alcoholic steatosis (NAS) activity score was evaluated by HE and Oil Red O staining. The relative expression level of F4/80 mRNA was compared by RT-PCR. Data comparison between groups was analyzed by t-test.Results:NASH model was successfully established by feeding the mice with MCD for four week. The expression of F4/80 mRNA ( t = 4.167, P < 0.01), hepatic steatosis ( t = 10.70, P < 0.05), interlobular inflammatory infiltration ( t = 3.08, P < 0.05), and NAS score were decreased ( t = 8.06, P < 0.05) in the experimental group. At the same time, ALT level [(817.00 ± 128.90) U/L vs. (231.20 ± 36.28) U/L, t = 5.71, P < 0.01], AST level [(1 211.00 ± 248.90) U/L vs. (505.30 ± 88.20) U/L, t = 3.32, P < 0.01] was decreased significantly. However, the spleen volume and spleen index of the experimental group were larger (0.24 ± 0.01 and 0.32 ± 0.02, t = 2.41, P < 0.05), and there was no significant effect on liver ballooning, body mass index and liver index. Conclusion:In NASH, phosphonate can consume macrophages to inhibit liver inflammation and protect the damaged liver.

Objective    To compare the efficacy of percutaneous closure guided by transthoracic echocardiography or angiography in the treatment of patent ductus arteriosus (PDA). Methods    Literature databases such as CNKI, VIP, Wanfang Database, PubMed, Cochrane Library were searched for collecting published literatures on percutaneous closure for PDA guided by transthoracic echocardiography and angiography, retrieval time limit was up to April 2019. Two evaluators independently screened the literature, extracted the data and evaluated the quality according to inclusion and exclusion criteria. The collected data were analyzed by RevMan 5.3 software. Results    Eight studies were included finally, with a total sample size of 681 cases. Meta-analysis showed that there was no statistical difference in the operative success rate between the echocardiography group and the angiography group (RR=0.99, 95%CI 0.97- 1.01, P=0.40). Postoperative complications were less in the echocardiography group than those in the angiography group (RR=0.26, 95%CI 0.11-0.59, P=0.001).The operation time (P<0.000 01), amount of intraoperative radiation (P< 0.000 01), exposure time (P<0.000 01), hospitalization days (P<0.000 01) and hospitalization costs (P<0.000 01) in the echocardiography group were less or shorter than those in the angiography group, and the difference was statistically different. Conclusion    Compared with angiography-guided, transthoracic echocardiography-guided percutaneous closure for PDA is a safe and effective method with less trauma, lower cost, and can replace angiography as one of the guiding methods for PDA.

Tetanus consists of neonatal tetanus and non-neonatal tetanus. Non-neonatal tetanus remains a serious public health problem, although neonatal tetanus has been eliminated in China since 2012. Non-neonatal tetanus is a potential fatal disease. In the absence of medical intervention, the mortality rate of severe cases is almost 100%. Even with vigorous treatment, the mortality rate remains 30%-50% globally. These specifications aim to regulate non-neonatal tetanus diagnosis and treatment in China, in order to improve medical quality and safety. These specifications introduce the etiology, epidemiology, pathogenesis, clinical manifestations and laboratory tests, diagnosis, differential diagnosis, grading and treatment of non-neonatal tetanus.
