Objective To investigate the clinical effect of endoscopic esophageal variceal ligation (EVL)in the treatment of esophageal variceal bleeding (EVB)in patients with liver cirrhosis.Methods A total of 84 liver cirrhosis patients with EVB who were admitted to The Third People′s Hospital of Shenzhen,Guangdong Medical University,from December 2010 to July 2013 were divided into ligation group (group A,treated with EVL combined with somatostatin and esomeprazole)and control group (group B,treated with somatostatin and es-omeprazole),with 42 patients in each group.The hemostasis rate,rebleeding rate,incidence rate of complications,and mortality rate were observed in both groups,as well as the variceal eradication rate after EVL and risk factors for early rebleeding.The t -test was used for com-parison of normally distributed continuous data between two groups,and an analysis of variance was used for comparison between multiple groups;the Mann -Whitney U test was used for comparison of non -normally distributed continuous data between two groups,the Wilcoxon signed -rank sum test was used for comparison within each group,and the Kruskal -Wallis H test was used for comparison between multiple groups.The chi -square test or Fisher′s exact test was used for comparison of categorical data between groups.The Kaplan -Meier method was used to calculate survival rates,and the log -rank test was used to compare survival rates between groups.The logistic regression meth-od was used to investigate the influencing factors for dichotomous data.Results There was a significant difference in the hemostasis rate be-tween groups A and B (97.62% vs 80.95%,P =0.029).Compared with group B,group A had significantly lower rebleeding rates in 1 -2 years (15.38% vs 38.89%,χ2 =5.323,P =0.021)and 2 -3 years (15.38% vs 48.48%,χ2 =10.448,P =0.001).A total of 14 patients (33.33%)in group A and 7 patients (16.67%)in group B experienced adverse events,and 4 patients in group A and 9 patients in group B died within 3 years.Group A had significant improvements in the levels of alanine aminotransferase (ALT)and aspartate amin-otransferase at 1 week after treatment (Z =-2.177 and -2.044,P =0.029 and 0.041).Both groups had significant improvements in pro-thrombin time activity (PTA),prothrombin time (PT),international normalized ratio (INR),and albumin at 1 week after treatment (group A:Z =-4.007,t =3.866,Z =-4.152,t =-4.623,all P <0.001;group B:t =-5.069,Z =-3.870,Z =-3.909,Z =-5.245,all P <0.001).There was a significant difference in PTA at 1 week after treatment between the two groups (Z =-3.902,P <0.001).In group A,the overall disappearance rate of varices was 85.71% and the recurrence rate was 14.29%,and there was a signifi-cant correlation between the Child -Pugh score and diameter of the portal vein (F =3.319,P =0.047).Symptoms on admission,length of hospital stay,Child -Pugh score,spontaneous bacterial peritonitis,diameter of the portal vein,PT,INR,and ALT were risk factors for ear-ly rebleeding after ligation (all P <0.05).Conclusion EVL is a safe and effective method for the treatment of EVB in patients with liver cirrhosis and causes few complications.

Objectives To study the relationship between serum HBV DNA and HBsAg, HBcAg expression in the hepatocytes in chronic hepatitis B(CHB) patients. Methods Quantitative polymerase chain reaction was used to assay the content of serum HBV DNA in 170 CHB patients. The expression of HBsAg and HBcAg in hepatocyctes was detected by immunohistochemical staining using liver biopsy. Results Although serum HBV DNA was negative, the expression of HBsAg in hepatocyctes was still observed in the CHB patients. In the CHB patients with lower level of serum HBV DNA, the positive rate of HBsAg expression in hepatocyctes was also lower (P

Objective: To investigate the quality of life among patients with occupational pneumoconiosis in Jinhua City, Zhejiang Province, so as to provide insights into improving the quality of life among patients with occupational pneumoconiosis. Methods: Patients with occupational pneumoconiosis in Jinhua City from 2009 to 2021 were retrieved from the National Occupational Disease and Health Risk Factors Monitoring Information System. Participants' demographics, diagnosis of pneumoconiosis, stage of pneumoconiosis, pulmonary function and medical expense were collected through questionnaire surveys, and the quality of life was measured using a Chinese version of the Short-Form Health Survey (SF-36). The quality of life was descriptively analyzed among patients with occupational pneumoconiosis by disease stage, pulmonary function, expense for disease diagnosis and treatment and educational level. Results: A total of 244 patients with occupational pneumoconiosis were enrolled, including 225 men (92.21%). The participants had a mean age of (75.20±9.42) years, and mean duration from dust contact to pneumoconiosis onset of (13.11±9.89) years. The scores for physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health were (64.03±31.22), (45.14±44.22), (56.34±26.60), (40.80±19.80), (59.14±17.35), (68.41±19.67), (47.03±44.08) and (61.15±17.06) points among patients with occupational pneumoconiosis, which were all lower than the national constant (P<0.05). Lower scores were measured for physical functioning [(31.17±23.40) points], bodily pain [(45.21±19.50) points] and vitality [(47.00±20.70) points] among patients with stage Ⅲ occupational pneumoconiosis, for physical functioning [(32.27±24.24) points], role-physical [(12.88±30.70) points], bodily pain [(37.44±20.43) points], general health [(14.76±17.17) points], vitality [(38.79±19.33) points], social functioning [(53.33±17.08) points], role-emotional [(9.09±26.71) points], and mental health [(53.21±17.25) points] among occupational pneumoconiosis patients with severe pulmonary function damages, and for physical functioning [(30.97±27.40) points], bodily pain [(37.77±24.34) points], general health [(19.10±18.62) points], vitality [(38.39±23.78) points], social functioning [(55.89±21.00) points] and mental health [(55.35±20.35) points] among occupational pneumoconiosis patients that had personal payments for pneumoconiosis diagnosis and treatment expenses exceeding 30% of annual household incomes, while higher scores were measured for physical functioning [(66.36±17.33) points] and role-physical [(59.09±45.10) points] among occupational pneumoconiosis patients with an educational level of high school and above (all P<0.05). Conclusions The quality of life was low among occupational pneumoconiosis patients in Jinhua City from 2009 to 2021. Stage of pneumoconiosis, pulmonary function, medical expenses and educational level were identified as factors affecting the quality of life among occupational pneumoconiosis patients in Jinhua City.

【Objective】 To estimate the prevalence, associated factors and patterns of multimorbidity of non-communicable diseases among adults in Shaanxi Province so as to provide evidence for the prevention and control of non-communicable diseases. 【Methods】 We used the data of adults aged 18 years and older collected in the baseline survey of Shaanxi Project in the Regional Ethnic Cohort Study in Northwest China. Multinomial logistic regression was used to explore the associated factors for multimorbidity. Exploratory factor analysis was used to extract patterns of multimorbidity. 【Results】 The prevalence of multimorbidity was 10.7% among the 44 442 participants. Age increase, being males, urban residence, and being overweight or obesity were positively associated with multimorbidity. Compared with women, men had a higher risk of multimorbidity. The OR and 95% CI was 1.25 (1.12-1.39). The risk of multimorbidity increased with age among adults. Compared with participants aged 18.0-34.9 years, the ORs and 95% CIs of those aged 35.0-44.9, 45.0-54.9, 55.0-64.9, and ≥65.0 years were 4.73 (3.47-6.46), 15.61 (11.60-21.00), 41.39 (30.76-55.70) and 90.04 (66.58-121.77), respectively. The primary multimorbidity patterns among adults in Shaanxi were cardiovascular-metabolic multimorbidity (5.4%), viscero-articular multimorbidity (1.0%), and respiratory multimorbidity (0.3%). 【Conclusion】 More than one in ten adults in Shaanxi Province had multimorbidity, and the predominant pattern of multimorbidity was cardiovascular-metabolic multimorbidity. The prevention and control of non-communicable diseases should be reinforced in middle-aged and older people, males, people living in the urban, and overweight or obese people. More attention should be paid to the prevention and control of cardiovascular-metabolic diseases.
