ABSTRACT

AIM: To understand the screening and correction of myopia in children and adolescents from the Gannan region of Gansu Province, and to provide guidance for the prevention and control of myopia.METHODS: A cross-sectional stratified cluster sampling study was conducted to select 2 kindergartens and 12 primary and secondary schools in Hezuo City and Zhouqu County, Gannan region of Gansu Province, two classes were randomly selected from each grade, and the whole class was used as a unit for screening. The screening and correction of myopia in children and adolescents were collected for statistical analysis.RESULTS: A total of 5 072 children and adolescents were selected, and 4 806 valid data were finally included after excluding unqualified records. The overall prevalence of myopia was 45.55%, and the prevalence of myopia showed an increasing trend with the increase of grade(P<0.001). The prevalence of myopia in girls(48.66%)was higher than that in boys(42.18%; P<0.001). The prevalence of myopia increased with age(P<0.001), and the age group of 10-12 years old was the fastest growing for myopia, increasing from 25.62% to 60.57%. Furthermore, moderate myopia and high myopia showed an increasing tread with the increase of the grade(all P<0.001). The overall glasses wearing rate of the Gannan region was 28.55%, with a full correction rate of 50.72%, and the glasses wearing rate showed an increasing trend with the increase of grades(P<0.001). The glasses wearing rate of female students(30.84%)was higher than that of male students(26.69%; P=0.008). The full correction rates of low, moderate and high myopia in junior high were the lowest among the 3 phases of studying. The full correction rate of high myopia was the lowest in all phases of studying.CONCLUSION: The prevalence of myopia in children and adolescents from the Gannan region is lower than the national average, but the myopia of children and adolescents is still a trend of young age and high incidence, and the glasses wearing rate of myopia and full correction rate are low.

ABSTRACT

Objective To investigate the long-term efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of primary biliary cholangitis (PBC) with portal hypertension. Methods A retrospective analysis was performed for 102 patients who received TIPS in Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2015 to August 2021, and these patients were divided into PBC group with 41 patients and viral hepatitis cirrhosis group with 81 patients. Related indicators were collected, including routine blood test results, liver and renal function, coagulation function, portal vein thrombosis, hepatic encephalopathy, and etiology of TIPS treatment shortly after admission, preoperative portal venous pressure, and stents used in surgery, and Child-Pugh score was calculated. Follow-up data were collected and analyzed, including postoperative upper gastrointestinal rebleeding, stent dysfunction, hepatic encephalopathy, and the data on survival and prognosis. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used for survival analysis, and the log-rank test was used for survival difference analysis. Results In the PBC group and the viral hepatitis cirrhosis group, the median percentage of reduction in portal venous pressure after surgery was 33.00% and 35.00%, respectively, and there was no significant difference between the two groups ( P > 0.05). At the end of follow-up, there were no significant differences between the PBC group and the viral hepatitis cirrhosis group in stent dysfunction rate (14.63% vs 24.69%, χ 2 =1.642, P > 0.05), upper gastrointestinal rebleeding rate (17.07% vs 24.69%, χ 2 =0.917, P > 0.05), the incidence rate of overt hepatic encephalopathy (12.20% vs 7.41%, χ 2 =0.289, P > 0.05), and disease-specific death rate (14.63% vs 9.88%, χ 2 =0.229, P > 0.05). Conclusion For PBC patients with portal hypertension, TIPS can achieve the same efficacy as the treatment of portal hypertension caused by viral hepatitis cirrhosis and can also effectively reduce portal hypertension without increasing the incidence rate of complications and disease-specific death rate. Therefore, it is a safe and effective treatment method.

ABSTRACT

Objective:To explore the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of esophago-gastric variceal bleeding (EGVB) complicated with cavernous transformation of portal vein (CTPV).Methods:From January 1, 2015 to December 31, 2018, the clinical data of liver cirrhosis patients with EGVB and complicated with (CTPV group) or without (non-CTPV group) CTPV receiving TIPS at Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were retrospectively analyzed. The success rate of operation, stent patency rate, recurrent bleeding rate, incidence and survival rate of hepatic encephalopathy of CTPV group and non-CTPV group were analyzed. Independent samples t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Kaplan-Meier method was used for survival analysis. Results:A total of 37 liver cirrhosis patients with EGVB and CTPV receiving TIPS treatment were screened out, among which 10 patients (27.0%) failed the portal vein puncture during the TIPS and switched to endoscopic treatment, the success rate was 73.0%. A total of 460 liver cirrhosis patients with EGVB and non-CTPV received TIPS treatment, among which TIPS in 18 patients (3.9%) was failed, and the success rate was 96.1%. With 1∶2 ratio propensity matching, 54 patients were enrolled in non-CTPV group. In the CTPV group, after TIPS treatment, the average portal vein pressure decreased from (28.9±5.1) mmHg (1 mmHg=0.133 kPa) to (18.8±4.5) mmHg, and the difference was statistically significant ( t=7.122, P<0.01). The median follow-up time was 33 months(1 to 66 months). There were no significant differences between the CTPV group and the non-CTPV group in one-year of cumulative stent patency rate (75.0% vs. 86.8%), recurrent upper gastrointestinal bleeding rate of hepatic encephalopathy (21.0% vs. 10.0%), the incidence of hepatic encephalopathy (34.8% vs. 22.2%) and the survival rate (80.7% vs. 88.9%)(all P >0.05). Conclusion:TIPS is safe and effective in the treatment of liver cirrhosis patients with EGVB and CTPV, and does not increase the incidence of postoperative complications and long-term mortality.
