BACKGROUND: Pulmonary arterial hypertension (PAH) presents a significant health burden in Asia and remains a critical challenge. This study aims to delineate the PAH burden in Asia from 1990 to 2021. METHODS: Using the latest data from the Global Burden of Disease 2021, we evaluated and analyzed the distributions and patterns of PAH disease burden among various age groups, sexes, regions, and countries in Asia. Additionally, we examined the associations between PAH disease burden and key health system indicators, including the socio-demographic index (SDI) and the universal health coverage (UHC) index. RESULTS: In 2021, there were 25,989 new PAH cases, 103,382 existing cases, 13,909 PAH-associated deaths, and 385,755 DALYs attributed to PAH in Asia, which accounted for approximately 60% of global PAH cases. The age-standardized rates (ASRs) for prevalence and deaths were 2.05 (95% uncertainty interval [UI]: 1.66-2.52) per 100,000 population and 0.31 (95% UI: 0.23-0.38) per 100,000 population, respectively. From 1990 to 2021, Asia reported the lowest ASRs for PAH prevalence but the highest ASRs for deaths compared to other continents. While the ASRs for prevalence increased slightly, ASRs for mortality and DALYs decreased over time. This increasing burden of PAH was primarily driven by population growth and aging. The burden was especially pronounced among individuals aged ≥60 years and <9 years, who collectively accounted for the majority of deaths and DALYs. Moreover, higher SDI and UHC levels were linked to reduced incidence, but higher prevalence rates. CONCLUSIONS Although progress has been made in reducing PAH-related mortality and DALYs, the disease continues to impose a substantial burden in Asia, particularly among older adults and young children. Region-specific health policies should focus on improving early diagnosis, expanding access to treatment, and effectively addressing the growing PAH burden in the region.

Background The population with diabetes in China is increasing year by year. Current research has found that either air pollution or temperature has an impact on the occurrence and development of diabetes, but the interaction between the two is unclear yet. Objective To investigate the effects and the lag effects of air pollutants and temperature on the risk of hospital admission for type 2 diabetes in Hefei, Anhui Province from 2016 to 2019, as well as to verify potential interaction between air pollutants and temperature. Methods This study collected hospital admission data for patients with type 2 diabetes from a tertiary hospital in Hefei, Anhui Province, and the corresponding monitoring data on air pollutants and meteorological factors from 2016 to 2019. Firstly, a distributed lag non-linear model (DLNM) was used to explore the effects of air pollutants and temperature on the risk of hospital admission for type 2 diabetes. Subsequently, a bivariate response surface model was used to explore potential interaction between temperature and various pollutants on frequency of hospital admission due to diabetes. Temperature was further divided into lower, medium, and higher levels by percentiles during the study period, and the potential interaction between air pollutants and temperature strata were verified . Results After controlling long-term trend, seasonal trend, holiday effect, and day of the week effect, the results of single pollutant models showed that for every 10 μg·m⁻³ increase in fine particulate matter (PM_2.5), inhalable particulate matter (PM₁₀), and nitrogen dioxide (NO₂), the relative risk (RR) values for hospital admission due to type 2 diabetes were 1.032 (95%CI: 1.021, 1.043), 1.018 (95%CI: 1.008, 1.026), and 1.037 (95%CI: 1.016, 1.058), respectively; for every 1 mg·m⁻³ increase in carbon monoxide (CO), the RR value for hospital admission due to type 2 diabetes was 1.319 (95%CI: 1.163, 1.495); the increases in sulfur dioxide (SO₂), ozone (O₃), and daily average temperature showed no statistically significant impact on hospital admission due to type 2 diabetes. The results of bivariate response surface models suggested that daily average temperature and various pollutant levels spontaneously affected the risk of hospital admission for type 2 diabetes, but the stratified analysis did not find significant differences in the effect of PM_2.5 on the risk of hospital admission due to type 2 diabetes across different temperature strata. Conclusion Increases in the concentrations of PM_2.5, PM₁₀, NO₂, and CO elevate the risk of hospital admission for type 2 diabetes. This study could not confirm the interactions between daily average temperature and various pollutants.

Objective To explore the expression of serum growth differentiation factor-8(GDF-8)and silent information regulator 4(Sir4)in elderly patients with chronic heart failure(CHF)and their relationship with left ventricular remodeling and cardiac function.Methods A total of 300 CHF patients admitted in our hospital from Jan 2021 to Dec 2023 were recruited and assigned into an observation group,and 100 healthy individuals who took physical examination during the same period served as control group.Based on New York Heart Association(NYHA)heart function classification,the patients in the observation group were divided into Grade Ⅰ(60 cases),Ⅱ(72 cases),Ⅲ(102 cases),and Ⅳ(66 cases)subgroups.Their clinical data were collected,serum GDF-8 and Sir4 levels were detected,left ventricular remodeling was evaluated with echocardiography,and cardiac dysfunction was assessed with NYHA cardiac function grading.Pearson and Spearman correlation analyses were used to analyze the correlation of GDF-8 and Sir4 levels with left ven-tricular remodeling and myocardial injury.Results The observation group had significantly larger left atrial diameter(LAD)and left ventricular end diastolic diameter(LVEDD),thicker left ven-tricular posterior wall thickness(LVPWT)and interventricular septum thickness(IVST),and higher left ventricular mass index(LVMI)and serum Sir4 and GDF-8 levels(42.46±4.75 mm vs 36.39±5.33 mm,54.63±7.96 mm vs 47.42±8.08 mm,9.44±1.21 mm vs 8.49±0.88 mm,9.27±1.58 mm vs 8.66±1.71 mm,141.49±5.32 g/m2 vs 106.52±7.33 g/m2,3.69±1.06 g/L vs 1.48±0.42 g/L,33.75±10.64 g/L vs 19.08±5.13 g/L,P＜0.01),but lower LVEF[(40.02±10.14)％vs(63.64±6.13)％,P＜0.01]and left ventricular remodeling index(LVRI,1.05±0.24 g/ml vs 1.32±0.33 g/ml,P＜0.01)when compared with the control group.The levels of Sir4 and GDF-8,as well as LVMI,were gradually increased,while the LVRI was decreased in Grades Ⅰ,Ⅱ,Ⅲ,and Ⅳ subgroups in turn,with statistical differences in the subgroups(P＜0.01).Pearson and Spearman correlation analyses showed that Sir4 and GDF-8 levels were positively correlated with LAD,LVEDD,LVPWT,IVST,LVMI,and NHYA cardiac function grade(P＜0.01),and nega-tively with LVEF and LVRI(P＜0.01).Conclusion Serum Sir4 and GDF-8 levels are abnormally elevated in elderly CHF patients,and their levels are positively correlated with the severity of left ventricular remodeling and the severity of cardiac dysfunction.

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 investigate the cognitive frailty of inpatients in Department of Geriatrics and analyze its influencing factors.Methods:This study was a cross-sectional study. Using the convenient sampling method, inpatients in Department of Geriatrics who were treated in Xuanwu Hospital of Capital Medical University were selected from June 2019 to June 2020. A total of 486 elderly patients who met the inclusion and exclusion criteria completed the questionnaire survey, physical examination and laboratory examination. The FRAIL Frailty Assessment Scale and Mini-Mental State Examination (MMSE) were used to evaluate cognitive frailty. Single factor analysis and Logistic regression were used to analyze the influencing factors of cognitive frailty in elderly inpatients.Results:The age of the survey subjects was (77.99±10.47) years old and the prevalence of cognitive impairment was 37.45% (182/486) . Logistic regression analysis showed that patients with a history of falls within 1 year, drinking, older age, anemia and ADL decline had a higher risk of cognitive impairment ( P<0.05) . Conclusions:The incidence of cognitive frailty is higher in elderly inpatients. Reducing the risk of falls, abstaining from alcohol, improving anemia and intervening to improve the ability of self-care in daily life may help to improve the cognitive frailty of the elderly.

Objective:To explore the clinical efficacy of internal fixation with a reduction plate assisted by our self-designed lower extremity fracture traction reduction device for tibial plateau fractures of Schatzker type Ⅵ.Methods:A retrospective study was conducted of the 32 patients with tibial plateau fracture of Schatzker type Ⅵ who had been treated at Orthopaedic Department, Mindong Hospital Affiliated to Fujian Medical University from April 2018 to July 2021. Depending on their treatments, they were divided into 2 groups. In the control group of 16 cases subjected to open reduction and internal fixation with manual traction, there were 9 males and 7 females with an age of 50.0±11.7 years; in the observation group of 16 cases subjected to internal fixation with a reduction plate assisted by our self-designed lower extremity fracture traction reduction device, there were 8 males and 8 females with an age of 54.6±11.1 years. The operation time, fracture reduction time, total incision length, intraoperative blood loss, Rasmussen knee function score and maximum active range of knee motion were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability between the groups ( P>0.05). The operation time [(158.6±26.0) min], fracture reduction time [(61.6±9.6) min], and total incision length [16.0 (13.3, 17.0) cm] in the observation group were significantly shorter than those in the control group [(199.9±60.9) min, (73.8±17.2) min, and 20.0 (17.0, 21.8) cm]; the intraoperative blood loss [175.0 (100.0, 200.0) mL] in the observation group was significantly less than that in the control group [200.0 (162.5, 387.5) mL]; the maximum active ranges of knee motion at one week and one month in the observation group were 94.9°±12.0° and 113.8°±14.1°, significantly larger than those in the control group (78.3°±14.6° and 96.8°±11.4°) (all P<0.05). Fractures achieved bony union at one year after operation in both groups. At 12 months after operation, there was no significant difference in the maximum active range of knee motion or the Rasmussen knee function score between the 2 groups ( P>0.05). Conclusion:In the treatment of Schatzker type Ⅵ tibial plateau fractures, compared with manual traction and open reduction, internal fixation with a reduction plate assisted by our self-designed lower extremity fracture traction reduction device can shorten operation time and total incision length, reduce intraoperative blood loss, and facilitate postoperative functional recovery of the knee for the patients.

ObjectiveTo investigate the clinical effect of vitamin E in the treatment of nonalcoholic fatty liver disease (NAFLD) in children. MethodsPubMed, Web of Science, The Cochran Library, Embase, OVID/NEJM, CNKI, and Wanfang Data were searched for the articles on vitamin E in the treatment of NAFLD in children published up to December 2019. The data of 8 parameters were analyzed, i.e., body mass index (BMI), liver enzymes ［alanine aminotransferase (ALT) and aspartate aminotransferase (AST)］, blood lipid levels ［triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL)］, and remission rate of hepatic steatosis. RevMan 5.3 was used to perform a Meta-analysis. Continuous variables were analyzed by standardized mean difference (SMD) and 95% confidence interval (CI), and the changes after intervention were analyzed; categorical variables were analyzed by risk difference (RD) and 95%CI. A fixed effects model was used for homogeneous data, and a random effects model was used for heterogeneous data. Funnel plots were used to evaluate publication bias. ResultsA total of 599 articles were retrieved, among which 9 were included in the Meta-analysis, with 607 subjects in total. Vitamin E significantly improved the level of ALT (SMD = -0.27, 95%CI: -0.48 to -0.06, P=0.01), but it did not improve the levels of BMI (SMD=-0.09, 95%CI: -0.28 to 0.10, P=0.34), AST (SMD=-020, 95%CI: -0.42 to 0.02, P=0.07), TG (SMD=-0.19, 95%CI: -0.51 to 0.12, P=0.22), TCHO (SMD=-0.11, 95%CI: -0.31 to 0.08, P=0.24), HDL (SMD=-0.02, 95%CI: -0.27 to 0.23, P=0.88), LDL (SMD= -0.04, 95%CI: -0.27 to 019, P=072), and the remission rate of hepatic steatosis (RD=0.06, 95%CI: -0.05 to 0.17, P=0.29). ConclusionVitamin E can significantly improve the level of ALT in children with NAFLD and can be considered as an adjuvant drug for clinical treatment.

Objective To explore the clinical application value of percutaneous kyphoplasty ( PKP ) under the guidance of G arm X ray machine in the treatment of osteoporotic vertebral compression fracture (OVCF). Methods The medical records of eighty-two patients (94 vertebral bodies) with OVCF treated with PKP were collected retrospectively. Thirty-nine cases ( 44 vertebral bodies ) were guided by G-arm X-ray machine to implement PKP,which were recorded as G-arm group. Forty-three cases (50 vertebral bodies) were guided by C-arm X-ray machine to carry out PKP,which were recorded as C-arm group. The operation time, intraoperative fluoroscopy times, bone cement leakage cases, preoperative and postoperative anterior height of injured vertebrae,Cobb angle of injured vertebrae,visual analogue scale scores and Oswestry disability index of the two groups were recorded. Results There was significant difference in operation time and intraoperative fluoroscopy times between the G-arm group and C-arm group (the operation time:(31. 6±5. 2) vs. (45. 8±6. 7) min,the intraoperative fluoroscopy times: (9. 5±2. 3) times vs. (18. 7±3. 5) times,t=-10. 64,-13. 91,P<0. 05) ,while there was no significant difference in the number of bone cement leakage ( P>0. 05) . Compared postoperative and preoperative anterior height of injured vertebrae, Cobb angle of injured vertebrae, visual analogue scale scores and Oswestry disability index scores of G-arm group and C-arm group respectively, the differences were significant ( t=-3. 41 vs. -3. 28, 6. 67 vs. 7. 66, 26. 63 vs. 25. 75 and 10. 41 vs. 11. 90, P<0. 05). There was no significant difference between the two groups (P>0. 05). Conclusion The treatment of OVCF with PKP guided by G-arm X-ray machine could significantly shorten operation time, reduce the intraoperative fluoroscopy times and the operative difficulty,and increase operation safety than PKP guided by traditional C-arm X-ray machine.
