【Objective】 To investigate the situation of hepatitis E virus(HEV) infection among voluntary blood donors in Wuhan area and provide evidences for enhancing blood screening strategies. 【Methods】 HEV nucleic acid detection(NAT) was performed on blood samples from eligible blood donors in Wuhan from November to December 2020. The testing results were analyzed, and the blood donors with repeated reactive results were followed up to clarify the status of infection. 【Results】 Routine screening was performed on 17 409 blood samples from November to December 2020. A total of 17 322 blood samples of eligible blood donors were tested for HEV NAT, and one case of HEV RNA reactivity was detected. The results from the follow-ups showed that the blood donor should be in the window period of HEV seroconversion. The current HEV infection rate of voluntary blood donors in Wuhan arewas 0.058‰(1/17 322), which was lower than other domestic areas. 【Conclusion】 The current HEV infection rate of voluntary blood donors was at a relatively low prevalence level in Wuhan area. Selective blood screening strategies can be taken to further reduce potential risk of blood transfusion infection with hepatitis E virus.

Objective Based on the global burden of disease (GBD) study data, to analyze the current situation and changing trend of refractive disorders in China by comparing Japan, India, the United States, the United Kingdom and the world. Methods The prevalence, years lived with disability (YLD) rate of refractive disorders from 1990 to 2019 were obtained from the global health exchange (GHDx）database. The disease burden and change trend of refractive disorders were analyzed using Joinpoint and other software. Results In 2019, the number of refractive disorders in China exceeded 27 million, with the prevalence and YLD rate were 19.18‰ and 89.40/100,000 respectively. From 1990 to 2019, the prevalence and YLD rate of refractive disorders showed an increasing trend globally (except India), with the largest increase in China (up by 53.21% and 53.96% respectively). The age standardized YLD rates in China, Japan, the United States, and the United Kingdom were all lower than the global average level, but China's age standardized YLD rates were higher than the developed countries (Japan, the United States, and the United Kingdom). Conclusion From 1990 to 2019, there was a certain gap between China and developed countries in the control of refractive disorders. Therefore, it is necessary to understand the disease status from a global perspective in order to better prevent and control refractive disorders in the future.

Objective To introduce the Socio-Demographic Index (SDI) and explore its relationship with disease burden indicators. Methods Based on the data of GBD 2017, we describe the correlation between HALE, DALY rate, YLD rate, YLL rate and SDI from 1990 to 2017 in the global and other 7 countries to explore the practical application value of SDI. Results 1. With the increase of SDI, HALE increased significantly; YLL rate and DALY rate decreased significantly. 2. The trend of YLD rate in low-SDI countries was the same as that of YLL rate and DALY rate; in the high-SDI and middle-SDI countries with longer life spans, as SDI increased, YLD rate also increased. 3. Because the socio-demographic characteristics of different diseases (such as Cardiovascular diseases and Neoplasms) are quite different, we should specifically analyze their relationship with SDI. Conclusion SDI is a good indicator, which can be used as an important covariate to predict disease burden and health outcomes in various areas.

OBJECTIVE: To discuss the effects of Lianhua Qingwen granules plus arbidol on treatment of mild corona virus disease-19 (COVID-19). METHODS: A total of 295 COVID-19 patients (2020.2.17-2020.3.6) in Wuhan Third Hospital were chosen and randomly assigned to control group (n=148) and observation group (n=147). The control group orally took arbidol and the observation group took Lianhua Qingwen granules and arbidol. TCM symptom scores, white blood count (WBC), lymphocyte count (LYM), C-reactive protein (CRP), procalcitonin (PCT) and chest CT review conditions were compared. RESULTS: Total effective rate in the observation group was significantly higher than control group ((80.95% vs. 64.86%); severe transfer rate in the observation group was lower than control group (14.29% vs. 23.65%) (P0.05); after 7 d of treatment, TCM syndromes like fever, weakness, cough, throat dryness and sore and chest discomfort, CRP and PCT levels in the observation group were significantly lower than control group (P0.05); WBC and LYM levels in the observation group were significantly higher than control group (P0.05); based on CT review, effective cure rate in the observation group (69.39%) and control group (62.84%) was not significantly different (P0.05). Both of groups had no serious adverse reactions. CONCLUSION: Lianhua Qingwen granules combined with arbidol can relieve the clinical symptoms, adjust the inflammatory factors, increase the curative effects and reduce the severe transfer rate.

Objective To analyze the current status and trends of chronic kidney disease (CKD) burden in China from the global perspective, and to provide reference for the prevention and control of CKD in China. Methods The incidence, prevalence, mortality and disability adjusted life year (DALY) rate of China and other regions were retrieved from GBD 2019. Comparative analyses were carried out to reflect the burden of CKD. Results In 2019, the incidence and the prevalence in females were higher than those in males, while the mortality and the DALY rates in females were lower than those in males. There were obvious distinctions in different age groups and people over 65 years old had a higher CKD burden. The burden of CKD mainly came from hypertensive nephropathy and type 2 diabetic nephropathy. From 1990 to 2019, the DALY rate of CKD in China showed an overall upward trend. After eliminating the differences in age composition, the standardized DALY rate of CKD in China was higher than that in Japan, Korea and Ukraine although lower than the global. The main influencing factors of the burden of CKD were metabolic factors. Conclusion The burden of CKD in China is continuously rising. It is still necessary to pay attention to the three-level prevention and control, and focus on the key people groups and high-risk factors to further reduce the burden of CKD in China.

【Objective】 To investigate the prevalence and risk factor of hepatitis E virus(HEV) infection among blood donors in Wuhan. 【Methods】 A total of 1 302 serum samples (including 1 076 with normal ALT and 226 with elevated ALT) from blood donors were randomly collected from January to December 2021 in Wuhan Blood Center. Anti-HEV IgG, IgM and HEV antigen (Ag) were examined by enzyme-linked immunosorbent assay (ELISA). The IgM or Ag positive and elevated ALT samples were subjected to real time-PCR to detect HEV RNA. Multivariable logistic regression modeling was used to examine the risk factors associated with HEV prevalence. 【Results】 Overall, the positive rates of anti-HEV IgG, IgM, and Ag were 16.44%, 1.0% and 0.08%, respectively. However, none of the serum samples were HEV RNA positive. The prevalence of anti-HEV IgG and anti-HEV IgM was similar in samples with increased ALT and normal ALT (IgG 13.72% vs 17.01%, P>0.05; IgM 1.33% vs 0.93%, P>0.05). Multivariate analysis revealed a strong statistical association between age and HEV IgG seroprevalence. The prevalence increased with increasing age, from 5.4% (18~25 years old) to 68.7%(the highest) in blood donors above 46 years (P<0.05). 【Conclusion】 HEV showed a seroprevalence among blood donors in Wuhan, some of whom were recent infections, suggesting a threat to the safety of blood transfusions. A low anti-HEV prevalence in young adults (18~25 years) is indicative of a susceptible population and implicates a higher risk of HEV infections in this age group in the future.

【Objective】 To explore the relationship between parental meta-emotion philosophy and family rearing environment in infants and toddlers, in order to provide guidance for building a positive family rearing environment. 【Methods】 The Parental Meta-Emotion Philosophy Scale was used to measure parents′ social emotions. Family rearing environment of infants was investigated by combining demographic data and Family Rearing Environment Scale. Independent sample t-tests, one-way analysis of variance, Spearman correlation analysis, and multiple linear regression were utilized to analyze the relationship between parental meta-emotion philosophy and the family rearing environment. 【Results】 A total of 370 infant caregivers were included in the study. The average age of infants was (27.81±7.76) months, with 192 boys (51.9%) and 178 girls (48.1%). Parents′ education level (F=4.71), whether they were the only child or not (t=8.85), whether the infant attended nursery or not (t=-2.49), and the per capita monthly income of the family (F=4.77) showed statistical significance in relation to the differences observed among the family rearing environments of infants and toddlers (P<0.05). Multivariate analysis indicated that the emotional teaching dimension of parental meta-emotion philosophy had a positive predictive effect on the overall level of the infant′s family rearing environment (β=0.50, 95%CI: 1.11 - 1.59), while the emotional loss dimension had a negative predictive effect (β=-0.15, 95%CI: -0.85 - -0.07). 【Conclusion】 The parental meta-emotion philosophy is closely related to the family rearing environment and serves as an important factor influencing it. It is supposed to improve parents′ emotional literacy and enrich their knowledge of parental meta-emotion philosophy, so as to help build a positive family rearing environment.

【Objective】 To investigate the prevalence of Hepatitis E virus (HEV) among blood donors in Wuhan urban agglomeration, aimed at providing data support for the development of HEV screening strategies for blood donors. 【Methods】 A total of 3 329 blood samples were collected from four centralized testing areas (Ezhou, Tianmen, Xiantao and Qianjiang) and screened at Wuhan Blood Center from January to December 2021. Among them, 2 737 were eligible blood samples with normal ALT (ALT normal group) and 592 were with elevated ALT (ALT elevated group). Enzyme linked immunosorbent assay (ELISA) was used to detect anti-HEV IgG, anti-HEV IgM and HEV-Ag, and Real-time PCR was used to perform single HEV RNA detection on blood samples with elevated ALT and normal ALT anti-HEV IgM+ blood samples. A two-sided Pearson’s chi-squared test or Fisher's exact test was used to evaluate the differences in the positive rates of anti-HEV IgG and anti-HEV IgM in different regions and ALT groups. 【Results】 The overall positive rates of anti-HEV IgG, anti-HEV IgM, and HEV-Ag in 3 329 blood samples from four regions were 21.63%, 1.29%, and 0%, respectively. There was a significant difference in the positive rates of anti-HEV IgG among blood donors in different regions (P<0.05). The highest positive rate of anti-HEV IgG was found in Tianmen 29.44% (136/462), followed by Qianjiang 22.69% (236/1 040), Xiantao 22.66% (230/1 015), and Ezhou 14.53% (118/812). The positive rates of anti-HEV IgG and anti-HEV IgM in blood samples with elevated ALT were significantly higher than that in normal ALT samples (25.68% vs 20.75%, 2.53% vs 1.02%, both P<0.05). However, none of the samples was HEV RNA positive. 【Conclusion】 HEV is prevalent among blood donors in Wuhan urban agglomeration with extremely low current infection rates, and the prevalence of anti-HEV IgG serum varies among different regions. The prevalence of anti-HEV antibodies in blood donors with elevated ALT is significantly higher than that in normal ALT donors.

OBJECTIVE To establish and apply a method for the determination of plasma concentration of delamanid （DLM）. METHODS After plasma samples were treated with methanol precipitation， LC-MS/MS was adopted to determine the plasma concentration of DLM. The chromatographic column was Phenomenex SynergiTM Fusion-RP with mobile phase of methanol-0.1% formic acid solution （gradient elution）. The column temperature was 40 ℃ ， the flow rate was 0.3 mL/min， and the sample size was 1 μL. The ion source was electrospray ion source， and positive ion scanning was carried out in multi-reaction monitoring mode. The DLM ion pair used for quantitative analysis was m/z 535.0→352.0. The plasma concentration of DLM in 6 multidrug resistant tuberculosis （MDR-TB） patients were determined by the LC-MS/MS method. RESULTS The linear range of DLM was 0.05-8 μg/mL （r＝0.999 5）， and the lowest limit of quantitation was 0.05 μg/mL. RSDs of intra-batch and inter-batch precision were all less than 10%. The accuracy ranged 92.7%-104.9%. Average matrix effect was 94.3%-107.5%. Average recoveries were 93.2%-98.1%. The plasma concentration of DLM in 6 MDR-TB patients ranged from 0.61-2.76 μg/mL， with an average of （1.67± 0.74） μg/mL. CONCLUSIONS The established LC-MS/MS analysis method has good specificity， high sensitivity， accuracy and precision， and can be used to determine DLM plasma concentration in MDR-TB patients.

Objective To summary the hospitalization costs of lung cancer patients, and analyze the influence factors in these patients, and provide basis for controlling hospitalization costs of lung cancer patients. Methods The hospitalization costs data of hospitalized lung cancer cases in Wuhan from 2018 to 2020 were collected from medical records. Nonparametric test was used to analysis the data for single factor analysis. The patients were divided into two groups according on the upper quartile value of hospitalization cost, that is high-cost group (the cost ≥ the upper quartile value) and normal cost group (the cost “four major hospitals in Hubei^” respectively. The hospital type is an independent influencing factors, compared with specialized hospital, the OR is 4.726 for general hospital. The hospitalization days is the independent influencing factors, more hospitalization days has high cost. The treatment mode is the independent influencing factors, compared with non-operative treatment, the OR is 556.129, 18.156 and 5.212 for surgical model, radio therapy model and interventional model respectively. Conclusion The age, hospital level, hospital type, hospitalization days and treatment mode are the independent influencing factors of hospitalization costs. To reduce the hospitalization cost of lung cancer patients, we should standardize the diagnosis of lung cancer patients, and focus on standardizing the treatment mode, also considering other influencing factors, such as hospital level, hospital type.
