ABSTRACT
OBJECTIVE@#To explore effect of nerve growth factor (NGF) antibody on knee osteoarthritis (KOA) pain model was evaluated by in vitro model.@*METHODS@#Thirty male SPF rats aged 28-week-old were divided into blank group (10 rats with anesthesia only). The other 20 rats were with monoiodoacetate (MIA) on the right knee joint to establish pain model of OA, and were randomly divided into control group (injected intraperitoneal injection of normal saline) and treatment group (injected anti-NGF) intraperitoneal after successful modeling, and 10 rats in each group. All rats were received retrograde injection of fluorogold (FG) into the right knee joint. Gait was assessed using catwalk gait analysis system before treatment, 1 and 2 weeks after treatment. Three weeks after treatment, right dorsal root ganglia (DRG) were excised on L4-L6 level, immunostained for calcitonin gene-related peptide (CGRP), and the number of DRGS was counted.@*RESULTS@#In terms of gait analysis using cat track system, duty cycle, swing speed and print area ratio in control and treatment group were significantly reduced compared with blank group (P<0.05). Compared with control group, duty cycle and swing speed of treatment group were significantly improved (P<0.05), and there was no significant difference in print area ratio between treatment group and blank group (P>0.05). The number of FG-labeled DRG neurons in control group was significantly higher than that in treatment group and blank group (P<0.05). The expression of CGRP in control group was up-regulated, and differences were statistically significant compared with treatment group (P<0.05).@*CONCLUSION@#Intraperitoneal injection of anti-NGF antibody inhibited gait injury and upregulation of CGRP in DRG neurons. The results suggest that anti-nerve growth factor therapy may be of value in treating knee pain. NGF may be an important target for the treatment of knee OA pain.

Objective: To investigate the clinical features and long-term prognosis of primary biliary cholangitis (PBC) in patients with past hepatitis B virus (HBV) infection. Methods: 353 cases with PBC who visited the Liver Disease Center of Beijing Friendship Hospital Affiliated to Capital Medical University between January 2000 and January 2018 were retrospectively analyzed and were divided into the past HBV infection group (156 cases) and the no HBV infection group (197 cases). The two groups' baseline clinical features were compared. Ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, and long-term liver transplantation-free survival rate were compared through outpatient and telephone follow-up. Results: PBC with past HBV infection had a significantly reduced female proportion compared to the no HBV infection group (91.9% vs. 79.5%, P = 0.001). However, there were no statistically significant differences in age, biochemical indices, immunological indicators, platelet count, cirrhosis proportion, and others. Ursodeoxycholic acid biochemical response rate was reduced in patients with past HBV infection at the end of one year of treatment, but the difference was not statistically significant (65.8% vs. 78.2%, P = 0.068). In addition, there were no statistically significant differences between the GLOBE score (0.57 vs. 0.59, P = 0.26) and UK-PBC 5-year (2.87% vs. 2.87%, P = 0.38), 10-year (9.29% vs. 8.2%, P = 0.39) and 15-year liver transplantation rates (16.6% vs. 14.73%, P = 0.39). Lastly, the overall 5-year liver transplantation-free survival rate had no statistically significant difference between the two groups of patients (86.4% vs. 87.5%, P = 0.796). Conclusion: Primary biliary cholangitis had no discernible effect in terms of age at onset, biochemical indices, immunological indicators, cirrhosis proportion, ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, or overall liver transplantation-free survival rate in patients with past hepatitis B virus infections.
ABSTRACT
BACKGROUND@#Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate.@*OBJECTIVE@#To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis.@*METHODS@#Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I2 statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests.@*RESULTS@#A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I2=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I2=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I2=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I2=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence.@*CONCLUSION@#Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

BACKGROUND@#Low back pain (LBP) is a prevalent and debilitating condition that poses a significant burden on healthcare systems. Acupuncture has been proposed as a promising intervention for LBP, but the evidence supporting its specific effect is insufficient, and the use of sham acupuncture as a control in clinical trials presents challenges due to variations in sham acupuncture techniques and the magnitude of the placebo effect.@*OBJECTIVE@#To investigate the magnitude of the placebo response of sham acupuncture in trials of acupuncture for nonspecific LBP, and to assess whether different types of sham acupuncture are associated with different responses.@*METHODS@#Four databases including PubMed, EMBASE, MEDLINE, and the Cochrane Library were searched through April 15, 2023, and randomized controlled trials (RCTs) were included if they randomized patients with LBP to receive acupuncture or sham acupuncture intervention. The main outcomes included the placebo response in pain intensity, back-specific function and quality of life. Placebo response was defined as the change in these outcome measures from baseline to the end of treatment. Random-effects models were used to synthesize the results, standardized mean differences (SMDs, Hedges'g) were applied to estimate the effect size.@*RESULTS@#A total of 18 RCTs with 3,321 patients were included. Sham acupuncture showed a noteworthy pooled placebo response in pain intensity in patients with LBP [SMD -1.43, 95% confidence interval (CI) -1.95 to -0.91, I2=89%]. A significant placebo response was also shown in back-specific functional status (SMD -0.49, 95% CI -0.70 to -0.29, I2=73%), but not in quality of life (SMD 0.34, 95% CI -0.20 to 0.88, I2=84%). Trials in which the sham acupuncture penetrated the skin or performed with regular needles had a significantly higher placebo response in pain intensity reduction, but other factors such as the location of sham acupuncture did not have a significant impact on the placebo response.@*CONCLUSIONS@#Sham acupuncture is associated with a large placebo response in pain intensity among patients with LBP. Researchers should also be aware that the types of sham acupuncture applied may potentially impact the evaluation of the efficacy of acupuncture. Nonetheless, considering the nature of placebo response, the effect of other contextual factors cannot be ruled out in this study. (PROSPERO registration No. CRD42022304416).
ABSTRACT
Objective:To compare the complications associated with various urinary flow diversion methods and identify the factors that contribute to the decline in renal function after radical total cystectomy for myoinfiltrating urothelial carcinoma.Methods:This study conducted a retrospective analysis on the clinical data of 46 patients with pathologically confirmed muscle-invasive bladder cancer.The patients underwent laparoscopic radical cystectomy with either ileal conduit diversion(n=21)or ureterocutaneous diversion(n=25)between January 2017 and December 2021.Perioperative data, postoperative pathology, postoperative complications, and follow-up results were compared between the two groups.Results:The study found significant differences between the two groups in terms of age[(67±6)years vs.(73±8)years, t=3.132, P=0.003], Charlson comorbidity index adjusted for age[(3.80±1.15) vs.(4.52±1.03), t=2.223, P=0.031], prognostic nutritional index[(48.81±5.74) vs.(43.64±4.74), t=3.347, P=0.002], operation time[(449±108)minutes vs.(326±130)minutes, P=0.001]], hospital stay[(20.1±11.1)days vs.(13.3±5.2)days, t=2.762, P=0.008], proportion of Clavien grade 3 or higher complications within 3 months after surgery(4/21 vs 0/25, χ2=2.105, P<0.05), and proportion of stoma-free patients(18/21 vs.5/25, χ2=6.373, P<0.01). According to Logistic multivariate analysis, perioperative blood transfusion and urinary tract infection were identified as independent risk factors for renal function decline 12 months after surgery.Escherichia coli was found to be the most common bacteria cultured from urinary tract infections in both groups after surgery. Conclusions:Laparoscopic radical cystectomy with ureterocutaneous diversion offers benefits such as shorter hospital stays and fewer perioperative complications for older and frail patients.However, a higher proportion of patients may require ureteral stenting.It is important to note that perioperative blood transfusion and urinary tract infection are major risk factors for renal function decline following radical cystectomy.
ABSTRACT
Objective:To investigate the clinical features, diagnosis, treatment and prognosis of primary urethral carcinoma.Methods:The clinical and follow-up data of 12 patients with primary urethral carcinoma admitted to Beijing Hospital from July 2016 to December 2020 were retrospectively analyzed.Results:There were four males and eight females, with an average age of 66.3(53~75)years.Nine patients underwent magnetic resonance examination before operation, and eight patients presented with abnormal urethral signals.The clinical stage of female patients was generally later than those of male patients, and all patients received surgical treatment.Four male patients did not receive post-operative adjuvant treatment, and all of them attained disease-free survival.Among the eight female patients, four patients received postoperative adjuvant radiotherapy or chemotherapy, five patients had recurrence or metastasis during follow-up, and two patients died.Conclusions:The clinical stage of female urethral cancer is later than that of male.MRI examination is beneficial to the determination of local invasion of urethral cancer.For female proximal urethral cancer and male posterior urethral cancer, radical resection has a good therapeutic effect.
ABSTRACT
Objective To investigate the dietary intake of preschool children in Northwest China, and provide scientific basis for studying the dietary patterns and characteristics of preschool children and formulating targeted dietary interventions. Methods Using the self-designed “Semi-quantitative Food Frequency Questionnaire for Preschool Children in Northwest China“, a convenient sampling method was used to investigate the dietary intake of children aged 3 to 7 years in Northwest China. The factor analysis combined with the cluster method was used to extract the dietary pattern. Results Through factor analysis of the average daily food intake of preschool children, the results show that the KMO test value was 0.82, Bartlett’s test value was 4 528.97, and the associated probability was <0.001, so factor analysis can be performed. In order to obtain more typical factor components so that the results were easier to explain, under the guidance of nutrition experts, the first 4 common factors were finally retained for analysis, and the cumulative variance contribution rate was 62.17%. On this basis, the number of clusters was 4, and the K-means cluster analysis method was used to cluster the factor scores of various foods for preschool children. According to the proportions of various foods and the characteristics of the foods, The dietary patterns of preschool children can be divided into staple food-based dietary patterns, high-protein dietary patterns, healthy dietary patterns, and high-sugar dietary patterns. Conclusion Using factor analysis method, the scores of each food factor of preschool children were continuous variables, and the results were highly repeatable, and subsequent analysis can be carried out. The factor analysis combined with cluster analysis method extracting the dietary pattern of preschool children that had certain degree of science. According to the characteristics of the four dietary patterns extracted in this study, children's dietary interventions can be targeted to promote children's physical and mental health.

ABSTRACT
Aim To study the protective effect of catechin on acute altitude injury in rats. Methods Rats were randomly divided into six groups: control group, altitude hypoxia model group, rhodiola capsule group, low -, middle-and high dose of catechin groups. After three days of preventive administration, animals were rushed to 4 010 m altitude. After five days of continuous administration, abdominal aortic blood of rats was collected for blood gas detection. Cardiac, brain and lung tissues were collected for HE staining to observe the pathological changes. MDA content, GSH content, NO content, SOD activity of myocardial, brain and lung tissues were detected, so were IL-6 and TNF-α content in serum. Results Compared with the control group, blood oxygen saturation of rats of altitud hypoxia model group was significantly reduced, while myocardial, brain and lung tissues were damaged to different degrees. MDA and NO content increased, while GSH content and SOD activity decreased. The serum inflammatory factors TNF-α and IL-6 levels were elevated significantly. After catechin treatment, blood oxygen saturation of hypoxia rats significantly increased (P < 0. 05). HE staining results showed that myocardial, brain and lung tissue injury was alleviated to some extent. MDA, NO, IL-6 and TNF-α content were down-regulated, while GSH content and SOD activity were up-regulated respectively. Conclusions Catechin can resist high altitude hypoxia and protect the main organs from hypoxia injury in rats acute exposed to altitude, which is related to alleviating oxidative stress and inflammation caused by acute hypoxia exposure.
ABSTRACT
BACKGROUND@#The placebo response of sham acupuncture in patients with primary dysmenorrhea is a substantial factor associated with analgesia. However, the magnitude of the placebo response is unclear.@*OBJECTIVE@#This meta-analysis assessed the effects of sham acupuncture in patients with primary dysmenorrhea and the factors contributing to these effects.@*SEARCH STRATEGY@#PubMed, Embase, Web of Science, and Cochrane CENTRAL databases were searched from inception up to August 20, 2022.@*INCLUSION CRITERIA@#Randomized controlled trials (RCTs) using sham acupuncture as a control for female patients of reproductive age with primary dysmenorrhea were included.@*DATA EXTRACTION AND ANALYSIS@#Pain intensity, retrospective symptom scale, and health-related quality of life were outcome measures used in these trials. Placebo response was defined as the change in the outcome of interest from baseline to endpoint. We used standardized mean difference (SMD) to estimate the effect size of the placebo response.@*RESULTS@#Thirteen RCTs were included. The pooled placebo response size for pain intensity was the largest (SMD = -0.99; 95% confidence interval [CI], -1.31 to -0.68), followed by the retrospective symptom scale (Total frequency rating score: SMD = -0.20; 95% CI, -0.80 to -0.39. Average severity score: SMD = -0.35; 95% CI, -0.90 to -0.20) and physical component of SF-36 (SMD = 0.27; 95% CI, -0.17 to 0.72). Studies using blunt-tip needles, single-center trials, studies with a low risk of bias, studies in which patients had a longer disease course, studies in which clinicians had < 5 years of experience, and trials conducted outside Asia were more likely to have a lower placebo response.@*CONCLUSION@#Strong placebo response and some relative factors were found in patients with primary dysmenorrhea.

【Objective】 To investigate the expressions of P53 and Ki-67 in prostate cancer (PCa)and to explore their correlation with the clinicopathological characteristics. 【Methods】 The expressions of P53 and Ki-67 in 90 PCa patients were detected with immunohistochemistry. Patients’ age, preoperative prostate-specific antigen (PSA) level, postoperative Gleason score, pathological stage, and invasion of neurovascular cancer embolus of all patients were recorded. The relationship of P53 expression with the above indexes was evaluated. 【Results】 The positive rates of P53 and Ki-67 were 27.8% (25/90) and 46.7% (42/90), respectively. The positive rate of P53 in pT2 and pT3-T4 stage groups were 19.7% (13/66) and 50.0% (12/24) (P=0.005), and the positive rate of Ki-67 were 36.4% (24/66) and 75.0% (18/24) (P=0.001), respectively. The positive rate of Ki-67 in Gleason score ≤6, ≤7 and ≥8 groups were 30.4%, 53.8% and 66.7%, respectively, with statistical difference. Positive expression of P53 was related to Ki-67 expression, but not to patients’ age, preoperative PSA level, postoperative Gleason score and nerve and invasion of neurovascular cancer embolus. 【Conclusion】 P53 expression is related to tumor stage and Ki-67, while Ki-67 expression is associated with tumor stage ang grade.
ABSTRACT
【Objective】 To reduce the misdiagnosis rate by analyzing the clinical data of patients with primary upper tract urothelial carcinoma (UTUC) complicated with calculi. 【Methods】 Clinical data of 7 UTUC with calculi patients treated during Sep.2018 and Apr.2022 were retrospectively analyzed, including general data, time from visit to diagnosis, imaging data, urine exudation cytological results, surgical methods, pathological stages and follow-up data. 【Results】 The ratio of male to female was 3∶4, and the mean age was 66.4 (55-72) years. The initiate imaging examination results only showed calculi, but did not indicate suspicious tumor (including 1 case with missing data). The median time from the first visit to diagnosis was 12 months (5-36 months). Of all 7 cases, 2 (2/4) were clinically diagnosed by enhanced CT, 3 (3/4) by MRI, and 2 (2/7) by positive urine exudation cytology. All patients received surgical treatment. Postoperative pathology showed 85.71% (6/7) were high-grade UTUC. Postoperative staging was T1N0M0 in 4 cases, T3N0M0 in 2 cases, and T4N2M0 in 1 case. Adjuvant chemotherapy was conducted in 2 cases. During the median follow-up of 12 months (6-41), 1 case developed multiple systemic metastases in month 9, while the other cases had no recurrence or metastasis. 【Conclusion】 For UTUC patients without obvious filling defect on imaging, especially when ipsilateral calculi were complicated, misdiagnosis should be alerted for timely treatment and better prognosis.
ABSTRACT
OBJECTIVE@#To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).@*METHODS@#From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12.@*RESULTS@#In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred.@*CONCLUSIONS@#GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI.

ABSTRACT
Objective:To assess the performance of liver and spleen stiffness measured by MR elastography (MRE) and their combined model in diagnosing liver fibrosis.Methods:From November 2018 to November 2019, 104 patients with chronic liver disease were prospectively enrolled in Beijing Friendship Hospital, all patients underwent MRE scans. Liver and spleen stiffness were measured from MRE elastograms. Liver biopsy was used to identify fibrosis stage (F0—F4). The differences among different fibrosis stages were analyzed by one-way ANOVA or independent samples t test. The Spearman rank correlation analysis was used to evaluate the correlation with fibrosis stages. Liver and spleen stiffness combined model was established by logistic regression. The ROC curve was used to evaluate the performance of the liver, spleen stiffness and combined model in staging fibrosis (≥F1), significant fibrosis (≥F2), advanced fibrosis (≥F3), and cirrhosis (F4).The area under the ROC curve(AUC) was compared using Delong test. Results:The liver and spleen stiffness both showed significant differences among the 5 fibrosis stages ( F=64.058, 32.890, both P<0.001). The liver and spleen stiffness were positively associated with fibrosis stage ( r s=0.89, 0.69, both P<0.001). The AUC of liver stiffness in staging ≥F1, ≥F2, ≥F3 were 0. 91, 0.97, 0.93, respectively. The corresponding AUCs of the spleen stiffness were 0.81, 0.82, 0.85, respectively, which were statistically lower than those of liver stiffness ( Z=2.283, 4.085, 2.314, P=0.022,<0.001, 0.021). In diagnosing F4, the AUCs of liver and spleen stiffness were both 0.95. The AUCs of the liver and spleen combined model were 0.92, 0.97, 0.93, 0.96 in diagnosing ≥F1, ≥F2, ≥F3 and F4, with no significantly differences from liver stiffness (all P>0.05). Conclusions:The liver stiffness measured with MRE have better diagnostic performance than spleen stiffness in staging fibrosis. Parameters combined model slightly improves diagnostic value but without significant difference with liver stiffness in staging early fibrosis. Spleen stiffness evaluation is feasible in detecting cirrhosis.
ABSTRACT
Objective:To investigate the effects of anesthesia depth control on cognitive function and high mobility group protein B1 (HMGB-1) level in older adult patients with breast cancer.Methods:Eighty-six female older adult patients with breast cancer who received mastectomy between June 2019 and June 2020 in the First Hospital of China Medical University, China were included in this study. They were randomly assigned to undergo anesthesia with sodium phenobarbital and atropine at deep (bispectral index 30-45, deep anesthesia group, n = 43) or superficial level (bispectral index 45-60, superficial anesthesia group, n = 43). The mean arterial pressure, heart rate, HMGB-1 level, Mini-Mental State Examination (MMSE) score were assessed in each group. Results:There were no significant differences in mean arterial pressure and heart rate recorded during each time period between the deep anesthesia and superficial anesthesia groups (all P > 0.05). No significant difference in HMGB-1 level was found between the two groups before anesthesia induction and at the end of surgery (both P > 0.05). At 1 and 2 days after surgery, HMGB-1 level in the deep anesthesia group was (75.46 ± 3.33) pg/mL and (93.98 ± 4.32) pg/mL, respectively, which was significantly lower than that in the superficial anesthesia group [(87.89 ± 5.13) pg/mL and (121.01 ± 4.36) pg/mL, t = 13.327, 28.878, both P < 0.05)]. At 1 day before surgery, there was no significant difference in MMSE score between the two groups ( P > 0.05). In the deep anesthesia group, MMSE score was (26.73 ± 1.11) points, (28.16 ± 0.72) points, and (28.97 ± 0.88) points at 1, 3 and 6 days after surgery respectively, which was significantly higher than that in the superficial anesthesia group [(21.03 ± 1.46) points, (22.39 ± 1.24) points, and (24.69 ± 0.57) points, t = 20.380, 26.388, 26.768, all P < 0.05]. Conclusion:Deep anesthesia for mastectomy in older adult patients can reduce cognitive impairment and decrease HMGB-1 level after surgery, and plays a positive role in postoperative recovery.

ABSTRACT
Objective@#The current study aims to explore precipitating and social risk factors for internet addiction (IA) in university undergraduate students, and to provide evidence for interventions and the early prevention of IA in different genders. @*Methods@#Four thousand eight hundred and fifty-eight college sophomores completed an online survey on their internet use-related behaviours and social risk factors. @*Results@#We found that more male (8.3%) than female students (5.4%) had moderate and severe IA. The main online activity in the moderate and severe IA groups was online gaming in males and online streaming in females. Roommates engaging in similar internetbased entertainment was a risk factor of IA only for males, while not being in a romantic relationship was a risk factor of IA for females only. Infatuation with the internet before college and adjustment problems for college life were shared risk factors for both genders in the mild and moderate IA groups. @*Conclusion@#IA was a common phenomenon in college students with shared and unique precipitating and social risk factors in males and females. The gender-sensitive risk factors for IA warranted earlier and individualized intervention and prevention strategies for IA in this population.

ABSTRACT
Liver cirrhosis is the leading cause of liver-related death globally, and the most common causes of liver cirrhosis are chronic hepatitis B and C, alcoholic liver disease, and nonalcoholic fatty liver disease. Recent studies have shown that despite an increase in the number of deaths due to liver cirrhosis around the world, there is a reduction in age-standardized death. In China, there are increases in number of patients with liver cirrhosis, prevalence rate of liver cirrhosis, number of deaths due to liver cirrhosis, and mortality rate of liver cirrhosis, while there are reductions in age-standardized prevalence rate and mortality rate; chronic hepatitis B remains the main cause of liver cirrhosis, with a gradual increase in the proportion of liver cirrhosis cases caused by alcoholic and nonalcoholic fatty liver diseases.
