Objective:To analyze the differences between subjective refraction and autorefraction in myopic children and adolescents under different ciliary muscle functional states.Methods:A cohort study was conducted.A total of 98 myopic children and adolescents (196 eyes) aged 7-15 years who visited the Shanghai Eye Disease Prevention and Treatment Center from November 2023 to February 2024 were included by random sampling.All participants underwent cycloplegia with 1.0% cyclopentolate and completed both subjective refraction and autorefraction before cycloplegia, after cycloplegia and after recovery from cycloplegia.The spherical equivalent (SE) differences and differences in SE(ΔSE) between different conditions were compared.Proportion of ΔSE, differences in spherical power (ΔS), and differences in cylindrical power (ΔC) of objective and subjective refraction between different conditions within the clinically acceptable error range (-0.25 to 0.25 D) was calculated and compared.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shanghai Eye Diseases Prevention & Treatment Center (No.2021SQ021).Written informed consent was obtained from guardian of each subject before any medical examination.Results:The SE values obtained from autorefraction before cycloplegia, after cycloplegia, and after recovery from cycloplegia were -2.44(-3.47, -1.63), -2.13(-3.25, -1.50), and -2.38(-3.50, -1.66)D, respectively, with a statistically significant overall difference ( χ2=148.36, P<0.001) and statistically significant differences in pairwise comparisons at different time points (all P<0.001); for subjective refraction, the SE values were -2.25(-3.50, -1.50), -2.19(-3.47, -1.45), and -2.28(-3.50, -1.50)D, respectively, with a statistically significant overall difference ( χ2=43.48, P<0.001) and statistically significant differences in pairwise comparisons at different time points (all P<0.001).Subjective refraction ΔSE between before and after cycloplegia, after cycloplegia and after recovery from cycloplegia were significantly smaller than those of autorefraction ( t=2.84, 1.82; both P<0.001).There was no significant difference in ΔSE between subjective refraction and autorefraction between before cycloplegia and after recovery from cycloplegia ( t=-0.43, P=0.070).The proportions of subjective refraction ΔSE within the acceptable error range between before and after cycloplegia, before cycloplegia and after recovery from cycloplegia, and after cycloplegia and after recovery from cycloplegia were significantly higher than those of autorefraction ( χ2=28.32, 11.82, 25.55; all P<0.001).The proportion of subjective refraction ΔS and ΔC both within the acceptable error range between before cycloplegia and after recovery from cycloplegia was 81.63%(160/196) and 79.59%(156/196) between after cycloplegia and after recovery from cycloplegia. Conclusions:Subjective refraction is less affected by different ciliary muscle functional states.The differences in subjective refraction results under different ciliary muscle functional states are mostly within the acceptable error range.The subjective refraction results before or after cycloplegia can be used to better predict the subjective refraction results after recovery from cycloplegia.

Objective:To investigate the status quo of the salary status of Guangxi's village doctors under the background of the implementation of"Employed by Townships and Work in the Villages"Policy.Methods:A total of 142 village doctors'salary data were obtained and sorted out through field investigation.Village doctors'salary level was analyzed with Chi-square test,rank test and correlation analysis.Results:More than 70%of village doctors'annual salary in the surveyed counties exceeded 50 000 yuan.Performance allowance is the main component of village doctors'annual salary.There are differences between the implementation number of"Employed by Townships and Work in the Villages"Policy and village doctors'annual salary level in different urban areas(P＜0.05).The village doctors'service population was positively correlated with the allowance of basic public health service,the general medical service population and the annual salary level(P＜0.05).Conclusion:Under the"Employed by Townships and Work in the Villages"Policy,the salary level of Guangxi's village doctors has been improved,and the salary component could be further optimized.It is suggest that the"Employed by Townships and Work in the Villages"Policy should be promoted in accordance with the economic development conditions of different urban areas,the income standards that match village doctors'academic,professional ranks,professional qualifications and working years,and the performance evaluation standards linked to village doctors'subsidy standards should be improved.

Head and neck squamous cell carcinoma(HNSCC)is a highly prevalent malignancy with poor prognosis.Treatment strategies to date have achieved limited success in significantly improving overall survival rates.γδ T cells,a unique subset of immune cells in the tumor microenvironment,can link adaptive and innate immune functions.While γδ T cells can effectively recognize and eliminate HNSCC tumor cells,certain subsets of these cells can secrete interleukin-17,contributing to tumor progression.Nevertheless,due to their remarkable cyto-toxic activity,γδ T cells have been identified as promising candidates for antitumor immunotherapy.This article reviews the biological back-ground of γδ T cells,their role in tumor immunity in HNSCC,and recent advances in γδ T cell immunotherapy,aiming to provide new in-sights into HNSCC diagnosis and treatment.

Objective:To investigate the incidence, clinical characteristics, and impact of spontaneous portosystemic shunt (SPSS) in patients with liver cirrhosis combined with hepatic encephalopathy (HE).Methods:The basic clinical and follow-up data were retrospectively analyzed for patients diagnosed with cirrhosis combined with HE at Mengchao Hepatobiliary Hospital of Fujian Medical University from January 2017 to December 2022. The patients were divided into large and small SPSS groups and a control group based on the results of abdominal enhanced CT or MRI.The clinical characteristics and outcome differences were compared among the three groups. Kaplan-Meier survival curves were used to compare HE-free survival time and overall survival time among the three groups. The log-rank test was used to compare the differences between groups. Cox regression analysis was used to identify the relevant risk factors affecting HE-free survival time and overall survival time.Results:A total of 223 cases with liver cirrhosis combined with HE were enrolled, including 150 in the SPSS and 73 in the control groups. The incidence rate of SPSS was 67.3% (150/223). The group was divided into small SPSS (79/150, 52.7%) and large SPSS group (71/150, 47.3%) according to the cross-sectional area of the diversion channel. The HE-free survival was shorter in the small and large SPSS groups compared with the control group (35.5 months in the small SPSS group and 21.3 months in the large SPSS group; P<0.001). The HE-free survival time was shorter in the large SPSS than with small SPSS group ( P=0.003). The overall survival time in the small SPSS group and the large SPSS group was shorter compared with the control group (small SPSS group: 39.4 months, large SPSS group: 52.9 months; P<0.001). There was no statistically significant difference in overall survival time between the small SPSS and large SPSS groups ( P=0.700). Cox regression analysis showed that SPSS was an independent risk factor affecting patients' HE-free survival time and overall survival time ( P<0.05). Conclusion:SPSS is more common in patients with liver cirrhosis combined with HE. Patients who combined with SPSS showed significant reductions in both HE-free survival time and overall survival time, especially evident in those with combined large SPSS.

Hepatic encephalopathy (HE) is a kind of neuropsychiatric syndrome caused by acute or chronic liver failure or portosystemic venous shunt (hereinafter referred to as portosystemic shunt), which can lead to the occurrence of functional impairment, personality and behavioral abnormalities, coma, and even death. Most patients with cirrhosis combined with HE have spontaneous portosystemic shunt (SPSS), especially those with recurrent or persistent HE. Internal medicine's current standard of treatment for HE associated with SPSS in cirrhotic patients is unsatisfactory, and even after treatment, recurrent HE episodes may still occur. Although interventional therapy has shown significant results and has been applied in clinical practice for many years for SPSS-associated HE, the number of treatment-related cases is relatively small, and there is a lack of large samples and well-designed research. Currently, interventional therapy for SPSS-associated HE in patients with cirrhosis is still under continuous exploration.

In recent years,the global public health sector has faced significant challenges due to the continuous e-mergence of novel infectious disease outbreaks,including Avian influenza virus infection,Ebola virus disease,and COVID-19.These epidemics not only threaten human health but also severely impact socioeconomic development worldwide.In response,innovative approaches in prevention and control of infectious diseases have emerged,dem-onstrating substantial value in practical applications in epidemic prevention and control.These methods play a cru-cial role in key areas such as dynamic monitoring of epidemic,optimization of prevention and control strategies as well as prediction of epidemic transmission trend,which remarkably enhance the precise prevention and control and boost the capability of rapid response.However,to fully realize their potentials,further integration of these innovative approaches with epidemiological theory is essential to develop a more robust methodological framework that can better adapt to the complexity of infectious diseases prevention and control and the dynamic change.
