Objective To adapt the upper extremity functional index (UEFI) to Chinese and assess the reliability and validity of the Chinese version.Methods The index items were translated into Chinese,back translated into English,and revised by experts in rehabilitation.Twenty-five patients with upper extremity trauma were then recruited to complete two UEFI questionnaires on two occasions 1 week apart as a field test.They also completed a disability of arm,shoulder and hand (DASH) questionnaire on the first occasion.Results Some adjustments were made to the translations based on cultural and linguistic practices.Cronbach's alpha for the final version was 0.93 and the total inter-class correlation coefficient (ICC) was 0.97.The ICCs of the individual items ranged from 0.56 to 0.94.The Pearson correlation coefficient between the UEFI and DASH questionnaires was-0.86.Conclusions The Chinese version of the UEFI scale is reliable and valid.It can be used for study and in the clinical evaluation of upper extremity function.

Objective To confirm the correlation between pre or post processing semen parameters and clinical pregnancy rate in infertile couples with male factors undergoing intrauterine insemination (IUI) .Methods The pregnancy rate based on ovulation in‐ducing agent in infertile couples with male factors infertility per the 2010 world health organization criteria treated with IUI was e‐valuated .One hundred and twenty eight cycles were divided into pregnant group (16 cycles) and non‐pregnant group(112 cycles) . The pre or post processing semen parameters were retrospectively evaluated .Results The overall pregnancy rate was 12 .5% .All parameters in this study has no statistically significant difference between the two groups (P>0 .05) .Logistic multivariate analysis showed that there was no significant correlation between semen parameters and clinical pregnancy rate (P> 0 .05) .Conclusion There are no significant correlations between semen parameters and clinical pregnancy rate when the normal forms of patients with male infertility was 4% or higher .No semen parameters could predict results of clinical pregnancy .

Objective:To investigate the effect of low-frequency ultrasound combined with hydroxychloroquine (HCQ) on the growth and invasion of 4T1 breast cancer in mice.Methods:4T1 cells in logarithmic growth phase were divided into 4 groups: control group, ultrasound group, HCQ group and ultrasound combined with HCQ group. Western blot was performed to detect the effects of ultrasound combined with HCQ on the protein expression levels of autophagy-related proteins LC3, p62 and matrix metalloproteinase 9 (MMP-9). Transmission electron microscopy was used to observe the formation of autophagic vesicles. The cell proliferation and cell viability were determined by EdU and CCK-8. Transwell assay was performed to detect the effect of ultrasound combined with HCQ on the invasive ability of 4T1 cells. Flow cytometry was performed to detect the effect of ultrasound combined with HCQ on the apoptosis of 4T1 cells. The transplantation tumor model of 4T1 breast cancer in BALB/c mice was constructed.The mice were randomly divided into 4 groups ( n=5 for each group), including control group, ultrasound group, HCQ group, ultrasound combined with HCQ group. The tumor volume and mice body weight were evaluated and measured in each group every 2 days. Results:The expression of LC3-Ⅱ and p62 protein levels increased in the ultrasound combined with HCQ group, and intracellular autophagosome accumulation was evident by transmission electron microscopy. In cellular experiments, compared with the other groups, the ultrasound combined with HCQ group showed stronger growth inhibition, significantly decreased cell proliferation rate, decreased expression of MMP-9, and significantly inhibited invasion (all P<0.050). In the in vivo experiments, compared with the control group, the tumor growth rate of all 3 inter vention groups of mice decreased (all P<0.050), and the ultrasound combined with HCQ group had better therapeutic effects than the ultrasound and HCQ groups. The treatment effect of ultrasound combined with HCQ group was better than that of ultrasound and HCQ groups (all P<0.001). Conclusions:The combination of low-frequency ultrasound and hydroxychloroquine could synergistically inhibit tumor cell proliferation, promote apoptosis, and significantly inhibit tumor growth in 4T1 tumor-bearing mice.

Overall progress of the Healthy China initiative highlights the importance of medical humanities in the connotation construction of health services, hence making standardized construction and effective governance of medical social workers a focus of the current healthcare reform. This study summarized the practices of medical social workers engaged in the cabin hospital in Wuchang district, Wuhan city, Hubei province during the outbreak of COVID-19. Their efforts aimed at reducing the stress faced by front-line medical workers, and assisting the patients to achieve body-mind balance for better treatment outcomes." Online+ offline" and" in-cabin+ out-of-cabin" service teams were organized to assist these medical staff, provide social support, and integrate resources. The study analyzed the problems and challenges in the process of practice, and provided a reference for further improving the management of public health emergency services.

Objective To investigate the correlation between the quality of life and joint health status of adult hemophilia patients. Methods Forty-nine adult hemophilia patients were selected.The quality of life and joint health status of patients were evaluated by hemophilia-specific health related quality of life questionnaire for adults (Hemo-QOL-A) and hemophilia joint health score (HJHS). Results The Hemo-QOL-A score of adult hemophilia patients was (39.34 ± 18.97) scores, and HJHS score was(33.16 ± 13.17)scores.The Pearson correlation analysis result showed that Hemo-QOL-A score was positively related with HJHS score (r = 0.490, P<0.05), and Hemo-QOL-A score was positively correlated with muscular condition,joint activity and joint friction sound score of HJHS score(r=0.469, 0.396 and 0.290; P<0.05). Hemo-QOL-A score was not correlated with swelling, swelling duration, arthralgia and gait of HJHS score (P>0.05). In 294 joints of 49 patients, the total abnormal rate of the joint was 82.7%(243/294),the abnormal rate of the elbow joint was 72.4%(71/98),the abnormal rate of the knee joint was 90.8%(89/98),and the abnormal rate of ankle joint was 84.7%(83/98).Conclusions Decreased joint health status, mainly including the surrounding muscle condition and joint mobility, results in lower quality of life in patients with hemophilia.

There are few reports of poisoning caused by high-dose intravenous injection of mercury. Its clinical manifestations are diverse and the risk of mortality is high. Currently, the pathogenesis is not clear and the treatment experience is insufficient, leading to difficulties in clinical diagnosis and treatment. In this article, the data of a case of mercury poisoning caused by intravenous self-administration was analyzed and summarized. The patient developed multiple organ dysfunction syndrome after intravenous injection of high-dose mercury. After comprehensive treatment, such as mercury removal, organ support, and infection prevention, the condition was improved. This case suggests that intravenous injection of mercury can cause damage to the functions of multiple organs, such as the heart, lungs, and kidneys. Early treatment and intervention can bring benefits.

With the rapid development of industry and economy,the emergence of a large number of chemicals has made of risk management more difficult.Traditional risk assessment relies on animal experiments for toxicity testing.However,animal experiments are time-consuming,costly,and unable to meet the practical needs of risk assessment.The increasing maturity of toxicity testing alternative technologies signifies the possibility of rapid,sensitive,and accurate identification of chemical toxicity.This article focuses on the research and applications of alternative toxicity testing by reviewing the background,developments,and current research at home and abroad.It also discusses the progress in alternative testing methods in such areas as cosmetics and food safety risk assessment and explores the problems with the development of alternative testing technologies and risk assessment in China.This review aims to provide a reference for the system construction of cosmetics health risk assess-ment in China.
