ObjectiveTo investigate the prevalence of muscle changes (including sarcopenia and myosteatosis) and related influencing factors in patients with porto-sinusoidal vascular disorder (PSVD), and to provide a theoretical basis for the early identification, prevention, and intervention of muscle changes in PSVD patients. MethodsA total of 132 PSVD patients who were diagnosed in Nanjing Second Hospital from July 2017 to July 2024 were enrolled as case group, and the hospital staff who underwent physical examination in 2025 were enrolled as healthy control group. Propensity score matching was performed based on age and sex at a ratio of 1∶1. According to muscle status assessed by abdominal CT, the subjects were divided into non-muscle change group, mild muscle change group (myosteatosis alone), and severe muscle change group (sarcopenia alone or sarcopenia comorbid with myosteatosis), with the type and severity of muscle change as the exposure factors. General information, laboratory tests, L3-level CT images, and liver biopsy data were collected for the patients in the case group, and general information and CT images were collected for the individuals in the healthy control group. Sarcopenia was diagnosed by measuring skeletal muscle index at the L3 level (<44.77 cm2/m2 for men and <32.50 cm2/m2 for women), and myosteatosis was defined by mean muscle attenuation combined with BMI (BMI <24.9 kg/m2 with attenuation <41 HU or BMI ≥25 kg/m2 with attenuation <33 HU). Demographic, laboratory, and clinical parameters were compared between the case group and the healthy control group. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The univariate and multivariate Logistic regression analyses were used to identify the factors associated with sarcopenia in PSVD. ResultsAmong the 132 patients with PSVD, there were 83 patients with portal hypertension (PH) and 49 patients without PH, and there were significant differences between these two groups in age, albumin, albumin/globulin ratio, leukocyte count, neutrophil count, red blood cell count, platelet count, direct bilirubin, indirect bilirubin, hemoglobin, blood calcium, cholinesterase, total bile acid, triglyceride, total cholesterol, prothrombin time, international normalized ratio, activated partial thromboplastin time, decompensation, gastroesophageal or ectopic varices, bleeding and ascites (all P<0.05). The analyses after matching showed that compared with the healthy control group, the case group had significantly higher prevalence rates of abnormal muscle structure (43.18% vs 18.94%, P<0.001), mild muscle changes (22.73% vs 7.58%, P<0.001), and severe muscle changes (20.45% vs 11.36%, P<0.001). Further comparison showed that there was no significant difference in the proportion of patients with muscle changes between the PSVD patients with PH and those without PH (42.17% vs 44.90%, P=0.760). The binary Logistic regression analysis with the presence or absence of muscle changes as the dependent variable showed that age (odds ratio [OR]=1.05, 95% confidence interval [CI]: 1.02 — 1.09, P<0.05), subcutaneous fat index (OR=1.03, 95%CI: 1.01 — 1.06, P<0.05), hemoglobin (OR=0.97, 95%CI: 0.95 — 0.99, P<0.05), and thrombin time (OR=1.26, 95%CI: 1.06 — 1.49, P<0.05) were independent influencing factors for muscle changes in PSVD patients. The multivariate ordinal Logistic regression analysis with the severity of muscle changes as the dependent variable showed that age (OR=1.04, 95%CI: 1.01 — 1.07, P<0.05) and thrombin time (OR=1.17, 95%CI: 1.01 — 1.36, P<0.05) were independent risk factors for the grading of muscle changes. ConclusionMuscle changes are common in PSVD patients, and these changes may be caused by PSVD itself rather than PH. Age, fat distribution, thrombin time, and hemoglobin are important influencing factors for muscle changes.

ObjectiveTo investigate the efficacy of C-reactive protein (CRP) in predicting the progression to acute-on-chronic liver failure (ACLF) within 90 days after disease onset in patients with acute decompensation (AD) of cirrhosis, and to provide a reference for the early identification of high-risk populations in clinical practice. MethodsA retrospective study was conducted among 906 patients with liver cirrhosis who were hospitalized due to AD in Nanjing Second Hospital from January 1, 2015 to October 31, 2024, and demographic features, AD type, and laboratory markers were collected on admission. The primary endpoint was progression to ACLF within 90 days after admission, and according to the presence or absence of ACLF, the patients were divided into non-ACLF group with 676 patients and ACLF group with 230 patients. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The univariate and multivariate Cox proportional-hazards regression models were used to identify independent predictive factors for ACLF. The receiver operating characteristic (ROC) curve was used to assess the predictive performance of CRP and existing scoring systems (Model for End-Stage Liver Disease [MELD], Child-Turcotte-Pugh [CTP] score, and Chronic Liver Failure Consortium Acute Decompensation [CLIF-C AD] score), and the restricted cubic spline analysis was used to investigate the nonlinear relationship between CRP and the risk of ACLF. Youden index was used to determine the optimal predictive cut-off value for CRP, and the Kaplan-Meier survival curve was plotted for risk stratification, while the log-rank test was used for survival analysis. ResultsAmong the 906 AD patients, the incidence rate of ACLF was 25.39% within 90 days. The incidence rate of ACLF within 90 days was 45.1% in the 264 patients with bacterial infection and 17.3% in the 642 patients without bacterial infection (χ²=74.791, P<0.001). Among the 906 patients, 312 patients (34.44%) had acute-on-chronic pre-liver failure (pre-ACLF), with a significantly higher proportion of patients who progressed to ACLF than those in the non-pre-ACLF group [60.58% (189/312) vs 6.90% (41/594), χ²=310.234, P<0.001]. Among the 230 patients with ACLF, there were 102 patients with stable ACLF (44.35%) and 128 patients with unstable ACLF (55.65%), with a significant difference in CRP between the two groups of patients (U=5 234.500, P<0.001). The restricted cubic spline analysis showed a significant nonlinear relationship between CRP and the risk of ACLF (P<0.001). The optimal cut-off value of CRP was determined as 10.16 mg/L based on the Youden index, with a sensitivity of 70.4% and a specificity of 64.5%. The Kaplan-Meier curve analysis showed that the high-risk group with CRP≥10.16 mg/L had a significantly higher event-free survival rate of ACLF within 90 days compared with the low-risk group (P<0.001). The multivariate Cox regression analysis showed that AD type-hepatic encephalopathy (hazard ratio [HR]=4.199, 95% confidence interval [CI]: 3.056 — 5.770, P<0.001), AD type-bacterial infection (HR=1.826, 95%CI: 1.356 — 2.459, P<0.001), CRP (≥10.16 mg/L) (HR=2.356, 95%CI: 1.825 — 3.047, P<0.001), white blood cell count (HR=1.021, 95%CI: 1.002 — 1.041, P=0.035), hemoglobin (HR=0.994, 95%CI: 0.989 — 0.999, P=0.025), international normalized ratio (HR=1.657, 95%CI: 1.372 — 2.001, P<0.001), total bilirubin (HR=1.003, 95%CI: 1.002 — 1.004, P<0.001), albumin (HR=0.956, 95%CI: 0.926 — 0.986, P=0.004), creatinine (HR=1.005, 95%CI: 1.004 — 1.006, P<0.001), serum sodium (HR=0.976, 95%CI: 0.956 — 0.997, P=0.025), and lactate dehydrogenase (HR=1.001, 95%CI: 1.001 — 1.002, P<0.001) were all independent predictive factors for progression to ACLF within 90 days. The ROC curve analysis showed that CRP alone had an area under the ROC curve (AUC) of 0.724 (95%CI: 0.685 — 0.763) in predicting ACLF, and CRP+MELD score had the best predictive performance (AUC=0.870, 95%CI: 0.843 — 0.898), while CRP+CTP score and CRP+CLIF-C AD score had an AUC of 0.852 (95%CI: 0.823 — 0.881) and 0.845 (95%CI: 0.812 — 0.877), respectively. There was a significant increase in model performance after integration (P<0.05). ConclusionSerum CRP level on admission is an independent predictive factor for progression to ACLF within 90 days in patients with AD of cirrhosis, and a CRP level of ≥10.16 mg/L can be used as a simple threshold for identifying high-risk patients. Incorporating CRP into existing assessment systems may enhance the early identification of patients at a high risk for ACLF, which provides a reference for clinical intervention.

AIM:To investigate the prevalence of ocular fundus lesions among active-duty military personnel with high myopia and to analyze the associated influencing factors.
METHODS: A cross-sectional study. Subjects included military personnel with high myopia(≤-6.00 D)and elongated axial length(≥26 mm). A systematic evaluation protocol was implemented, consisting of standardized questionnaires, general physical health examinations, and comprehensive ophthalmic assessments. Optical coherence tomography(OCT)was used to screen for fundus lesions in highly myopic subjects, and the prevalence of related lesions was calculated. Axial length, refractive error, best-corrected visual acuity(BCVA), and macular ganglion cell complex(GCC)thickness were measured. Univariate analysis was performed to compare differences in the above parameters between highly myopic subjects with and without concomitant fundus lesions. Multivariate Logistic regression analysis was further applied to identify risk factors for fundus lesions.
RESULTS:A total of 134 male patients(268 eyes)were enrolled, with the mean age of 24.5±3.2 y. Of the 268 eyes, 123 eyes(45.9%)showed positive signs of fundus lesions. Among these, parapapillary blood flow density reduction was found in 84 eyes(31.3%), GCC thinning in 46 eyes(17.2%), drusen in 8 eyes(3.0%), optic disc edema in 7 eyes(2.6%), retinoschisis in 6 eyes(2.2%), and choroidal excavation in 3 eyes(1.1%). BCVA was significantly lower in highly myopic patients with retinoschisis than in those without retinoschisis(P<0.05).Univariate analysis showed that refractive error, axial length, and posterior scleral expansion were associated with the occurrence of fundus lesions(P<0.05). Multivariate Logistic regression analysis revealed that axial length(OR=2.52, 95%CI: 1.67-3.80, P<0.001)and posterior scleral expansion(OR=3.12, 95%CI: 1.65-5.92, P<0.01)were significant risk factors for fundus lesions in highly myopic military personnel.
CONCLUSION: The prevalence of fundus lesions is relatively high among active-duty military personnel with high myopia. Peripapillary flow density reduction and GCC thinning are the most common manifestations in this population. Increased axial length and posterior scleral ectasia are significant contributing factors. It is recommended that OCT be incorporated into routine ophthalmic examinations for these military personnel, thereby providing a basis for the early detection and intervention of fundus lesions.

ObjectiveTo analyze the changing trend of the disease burden of acute viral hepatitis (AVH) globally and in China from 1990 to 2021, and to provide a basis for optimizing prevention and control strategies. MethodsRelated data were extracted from the Global Burden of Disease 2021 database, including incidence rate, mortality rate, and disability-adjusted life years (DALY) for AVH globally and in China from 1990 to 2021, and the patients were divided into groups according to region, age, sex, and type of hepatitis. The Joinpoint regression model was used to calculate average annual percentage change (AAPC) and its 95% confidence interval (CI). ResultsFrom 1990 to 2021, there was a tendency of reduction in the age-standardized incidence rate, mortality rate, and DALY rate of AVH globally, with an average annual reduction of 1.02% (95%CI: -1.10% to -0.94%, P<0.001), 3.97% (95%CI: -4.12% to -3.82%, P<0.001), and 3.64% (95%CI: -3.84% to -3.44%, P<0.001), respectively; in China, there was also a tendency of reduction in these indicators, with an average annual reduction of 1.63% (95%CI: -1.70% to -1.57%, P<0.001), 9.24% (95%CI: -9.51% to -8.97%, P<0.001), and 7.93% (95%CI: -8.15% to -7.71%, P<0.001), respectively. In addition, China’s share of the global disease burden of AVH continued to decrease; the proportion of new cases decreased from 24% in 1990 to 15% in 2021, the proportion of deaths decreased from 19% to 4%, and the proportion of DALY decreased from 16% to 4%. From 1990 to 2021 globally, the peaks in the incidence rate, mortality, and DALY of AVH were observed in children under 5 years of age; in China, although the peak incidence rate of the disease was still observed in children under 5 years of age, there was a tendency of increase in the incidence rate of AVH among young adults aged 25 — 29 years in recent years, with the most significant increase in the cases of acute hepatitis B (accounting for 59% of the cases in this age group), while the disease burden of mortality and DALY mainly affected the middle-aged and elderly populations. The disease burden of AVH in the male population was higher than that in the female population. As for the distribution of disease types, acute hepatitis A was the predominant type of AVH, accounting for 64% globally and 48% in China, whereas acute hepatitis B was the leading cause of mortality and DALY, accounting for 50% of deaths globally, 80% of deaths in China, 47% of DALY globally, and 69% of DALY in China. ConclusionThere is a tendency of reduction in the disease burden of AVH globally and in China from 1990 to 2021, but there is a tendency of increase in the incidence rate of AVH among young adults in China, especially acute hepatitis B. It is necessary to implement targeted prevention and control strategies.

Objective:To observe the effect of electroacupuncture on depression in chronic pain mice; To explore its mechanism.Methods:36 C57BL/6J mice were divided into a blank control group, a sham-operation group, a model group, and an electroacupuncture group using a random number table method, with 9 mice in each group. The chronic compression injury model of sciatic nerve was established in the model group and electroacupuncture group. Mechanical pain threshold (MWT) and latent heat wave leg reflex (TWL) were measured on preoperative day 1 and postoperative days 4, 7, 14, 21, and 35. Electroacupuncture treatment was performed on the 14th day after modeling, and on the 35th day after modeling, open field experiments, elevated cross maze experiments, forced swimming experiments, and tail suspension experiments were conducted to evaluate depressive like behavior in mice. Western blot was used to detect the protein expressions of glutamate receptor 1 (GluA1), glutamate receptor 2 (GluA2), human glucose transporter 3 (GLUT3), and calmodulin dependent protein kinase Ⅱ (CaMKⅡ) in the hippocampus of each group of mice; GluA1 positive cells in the hippocampus of mice was observed using immunofluorescence technology.Results:Compared with the blank group, the MWT and TWL value of the model group decreased ( P<0.05) on postoperative days 4, 7, 14, and 21. Compared with the model group, the electroacupuncture group had a longer stay time in the central area of the open field ( P<0.01), an increased percentage of stay time and activity frequency in the elevated arm opening ( P<0.01), a shorter static time for forced swimming ( P<0.01), and a shorter immobility time for the suspended tail ( P<0.01). Compared with the model group, the expressions of GluA1, GLUT3, GluA2, and CaMKⅡ proteins in the hippocampus of mice in the electroacupuncture group increased ( P<0.05), and the number of GluA1 positive cells increased ( P<0.05). Conclusion:Electroacupuncture can affect synaptic plasticity by regulating the AMPA receptor in the hippocampal region, thereby improving depressive mood caused by chronic pain.

Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital,in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points,and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases,including 1-21 cases in the learning stage,22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases,the postoperative bladder irrigation time reduced \[40.00 (26.00,44.50) h vs. 23.00(20.50,34.00) h vs. 23.50(14.75,40.75) h\],with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\],while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\],catheter indwelling time \[70.0 (66.0,106.0) h vs. 71.0 (66.0,89.0) h vs. 66.0 (58.5,78.5) h\],and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend,but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals,TUBVP is a worthy choice.

Objective To investigate the growth, development and health status of primary and secondary school students in Xinzhou District of Wuhan, and analyze the detection and change trend of common diseases in primary and secondary school students, and to provide a basis for relevant departments to formulate prevention and control measures of common diseases in students. Methods The monitoring data of common diseases and health influencing factors of primary and secondary school students in Xinzhou District from 2019 to 2022 were analyzed and compared according to different genders, different grades and ages. SPSS 20.0 software was used to analyze the data of detection rates of myopia, dental caries, obesity, malnutrition and abnormal spinal curvature. Results The overall detection rates of myopia, dental caries, malnutrition, obesity and abnormal spinal curvature were 57.00%, 58.45%, 4.60%, 14.91%, and 6.33%, respectively, in Xinzhou District from 2019 to 2022. The annual change rates were 7.22%, 15.10%, -2.72%, 13.29%, and 4.91%, respectively. The detection rates of myopia, dental caries, obesity and abnormal spinal curvature showed an increasing trend in each year (χ2 ≥17.22, P<0.001). The detection rates of myopia and malnutrition increased with the increase of age and school level (both χ2≥42.37, P<0.001), while the opposite was true for the detection rates of dental caries and obesity (both χ2≥14.26, P<0.001). The detection rates of myopia and dental caries were higher in girls than in boys (both χ2≥33.66, P<0.001), while the detection rates of obesity and abnormal spinal curvature were higher in boys than in girls (both χ2≥8.22, P<0.005). The detection rates of myopia, dental caries, obesity and abnormal spinal curvature in 2019 were lower than those in 2020-2022 (χ2≥4.11, P<0.05), while the detection rates of malnutrition had decreased. Conclusion The growth, development and health status of primary and secondary school students in Xinzhou District are serious. The detection rate of common diseases such as myopia, dental caries, obesity and abnormal curvature of the spine is on the rise, which should be the focus of the surveillance work of common diseases in primary and secondary school students in the future, and comprehensive intervention measures are urgently needed to prevent and control these common diseases.
