With the appearance of direct-acting antivirals (DAAs), breakthroughs have been achieved in the antiviral therapy for hepatitis C and hepatitis C patients can be cured completely. Due to the insidious onset of hepatitis C, most patients do not know their own conditions, and thus expanding diagnosis and treatment through screening is the key to the elimination of hepatitis C. However, hepatitis C virus is distributed widely and unevenly in the world, which results in difficulties in the screening and diagnosis of hepatitis C. This article introduces the current economic research on hepatitis C screening, analyzes the factors affecting the cost-effectiveness of hepatitis C screening, and shares the strategies and advances for hepatitis C elimination in other countries, so as to provide a reference for eliminating hepatitis C in China.

Objective:
To understand the prevalence and influencing factors of scoliosis among primary and middle school students in Shanghai, so as to provide reference for the prevention and control strategies of scoliosis in children and adolescents.
Methods:
From September to December 2021, a total of 4 531 students from grade four of primary school to grade three of junior high school from 16 primary and middle schools in 4 districts of Shanghai were selected by multi stage stratified cluster sampling to carry out scoliosis screening and questionnaire survey. Independent sample t-test, Chi-squared test, Fisher s exact probability method and nonparametric Mann Whitney U-test were used for statistical analysis, and multivariate Logistic regression was used to analyze the influencing factors of scoliosis.
Results:
The on the spot detection rate of scoliosis abnormality was 7.4% and the prevalence was 2.2%, mainly for thoracolumbar scoliosis (60.4%) and the scoliosis angle of 10° -<20°(88.1%). The results showed that the detection rate of scoliosis in boys was 1.6% and in girls was 3.3%, with a statistically significant difference ( χ 2=11.84, P < 0.01). There were significant differences in weight and BMI between scoliosis students and students with negative initial screening( t = -3.77, -5.30, P <0.01). And there was a statistically significant difference in the detection rate of scoliosis with different frequency of classroom seating arrangements ( Z =2.02, P <0.05). The results of multivariate Logistic regression showed that the risk of scoliosis in girls was higher than that in boys ( OR =1.87, 95% CI =1.21-2.88). BMI ( OR =0.89, 95% CI =0.83-0.95) and frequency of classroom seating arrangements ( OR =0.49, 95% CI =0.25-0.93) were correlated with lower rate of scoliosis. After stratification by sex, the frequency of classroom seating arrangements ( OR =0.26, 95% CI =0.10-0.67) in boys and the educational stage ( OR =2.35, 95% CI =1.26-4.41) in girls ( P <0.05) was correlated with higher rate of scoliosis, while BMI ( OR =0.86, 95% CI =0.79-0.94) in girls were correlated with lower rate of scoliosis.
Conclusion
Regular screening of scoliosis is an effective method for early detection of scoliosis. Girls in junior high school and low BMI should be paid close attention to. According to the occurrence and influencing factors of scoliosis, comprehensive prevention and control based on family, school, society, and other aspects can be carried out.

PURPOSE: An older female predominance has been reported among chronic cough patients in Western countries, which is considered to be associated with a higher cough sensitivity in females. However, the characteristics of Chinese chronic cough patients remain unclear. This study aimed to explore the age and sex distribution as well as their relationship with cough reflex sensitivity to capsaicin in Chinese chronic cough patients. METHODS: We analyzed the demographic features of 1,882 consecutive chronic cough patients who attended our cough clinic in Guangzhou, China. Cough sensitivity to capsaicin, which was defined as the lowest concentration of capsaicin causing 5 coughs or more (C5), was measured in 539 of the 1,882 patients and 68 healthy volunteers. RESULTS: The mean age of the patients was 43.0 ± 13.7 years and patients aged <50 years accounted for more than two-thirds of the study population. Around 87% of the patients were never-smokers. The proportion of females (51.5%) was almost equal to that of males (48.5%). The pattern of the age and sex distribution was consistently reflected within most common causes of chronic cough, while a female predominance was shown in patients with cough-variant asthma and patients aged ≥50 years. Female patients had higher cough sensitivity to capsaicin than male patients (log C5: 1.58 ± 0.84 vs. 2.04 ± 0.84 μmol/L, P = 0.001), and patients aged ≥50 years had higher cough sensitivity to capsaicin than patients aged <50 years. CONCLUSIONS: In China, patients with chronic cough have a roughly equal sex distribution and a middle-aged predominance, irrespective of a higher cough sensitivity to capsaicin in females and older patients.
