Spinocerebellar ataxia type 6(SCA6)is a group of autosomal dominant hereditary diseases characterized by cerebellar ataxia,with the typical feature of genetic anticipation.This study reports a family case of SCA6 to enhance understanding of the disease and improve clinical diagnosis rate.The patient was a 61-year-old male,presented mainly with slurred speech and unsteady gait,accompanied by dizziness,choking on drinking water,numbness of limbs,and insomnia.Evoked potential,nerve conduction studies,skin sympathetic responses,electroencephalogram,dementia rating scale,and other tests showed no significant abnormalities.Head MRI revealed marked cerebellar atrophy,and genetic testing confirmed SCA6.His father exhibited similar symptoms,while his daughter was a carrier of the abnormal gene.The patient received treatment including nutritional support,improvement of ataxia,and rehabilitation training.After a one-year follow-up,there was no significant progression of the disease.

Objective:To investigate the diversity, temporal dynamics and influencing factors of serotypes of Salmonella among asymptomatic workers in Yulin, Guangxi Zhuang Autonomous Region, from 2013 to 2023, and provide reference for controlling the hidden transmission of Salmonella and for disease prevention among healthy populations. Methods:Anal rectal swabs were collected from asymptomatic workers in Yulin from 2013 to 2023 for the isolation and identification of Salmonella. The diversity of serotypes of Salmonella was evaluated by using Shannon index, while the isolation rates and composition ratio of different serotypes were compared with χ2 test. Spearman correlation analysis was used to evaluate the correlation of natural and social factors with serotype isolation rates for more than eight years, and stepwise multiple linear regression analysis were used to evaluate the impact of social factors on the serotype isolation rates for more than 8 years. Results:A total of 8 073 strains of Salmonella were isolated from 2013 to 2023, with an overall isolation rate of 18.88‰ During the 11-year period, 135 serotypes of Salmonella were identified, and the serotype diversity increased first and then decreased. The serotype with the highest isolation rate was Salmonella Typhimurium (3.04‰), followed by Salmonella Rissen (1.70‰), Salmonella Corvallis (1.41‰), Salmonella Agona (1.36‰), Salmonella Derby (1.22‰), and Salmonella London (1.02‰), accounting for 51.67% of the total Salmonella serotypes isolated. There was no significant trend in isolation rate of Salmonella over the years ( χ2=0.67, P=0.415); however, season significantly influenced the isolation rate, with lower rate being observed in winter and higher rate in summer ( χ2=615.91, P<0.001). The isolation rate of different serotypes of Salmonella was influenced by social and natural factors, showing a positive correlation with temperature, precipitation, and poultry consumption and production levels. Conclusions:The serotypes of Salmonella carried by asymptomatic workers were complex and diverse in Yulin, Guangxi Zhuang Autonomous Region, from 2013 to 2023, and the isolation rates of multi-serotypes increased from 2013 to 2023. Higher isolation rate was observed in summer and the isolation rate was widely influenced by natural factors such as temperature and precipitation, as well as social factors such as economic conditions. It is necessary to pay attention to the Salmonella serotype carriage in healthy population, and strengthen monitoring of both healthy individuals and pathogenic bacteria.

Abstract Health literate schools (HeLit-Schools) play a significant role in fostering students health literacy. The paper elucidates the background and conceptual connotations of HeLit-Schools, and analyzes how HeLit-Schools effectively integrate and enhance the health literacy of schools in three aspects: philosophy and core drivers, strategy and method implementation, as well as evaluation mechanisms and standard setting. Furthermore, the paper explores the implications of foreign HeLit-Schools research and practice for China under the context of "Healthy China" construction, as well as the key strategies for Chinese schools in the implementation of HeLit-Schools, aiming to provide a new perspective and theoretical support for Chinese schools to practice the "Healthy China initiative" and strengthen school construction from the perspective of health literacy.

The cost-effectiveness analysis policy for drugs was institutionalized in Japan since 2019， realizing quantitative adjustment of price across varieties. A hierarchical categorization approach was adopted to select medicines with high expected annual sales. For selected medicines， adjustments were made to the premium and profit components within the existing price structure based on a pre-defined incremental cost-effectiveness ratio （ICER） threshold， effectively resolving the issue of inconsistent criteria and magnitudes caused by subjective judgment. Meanwhile， incentive measures like evaluation exemption or threshold enhancement were granted for specific medicines. Besides， a price adjustment mechanism， which was allowed for upward and downward adjustments， involving tiered ICER threshold and quantified formulas， had been established for the premium and profit components of drug price. In China’s National Reimbursement Drug List （NRDL） access， certain issues remained to be addressed： insufficient clarity in the quantitative mechanism of price formation， incomplete price adjustment measures， and lagging in the communication channels. It is recommended that the following measures could be referred to when further improving the scientificity and fairness of drug pricing during China’s NRDL access， such as enhancing the ICER threshold for medicines catering to special populations， quantifying criteria and extents for price adjustment， granting preferential pricing policies to pharmaceutical companies that present high-quality evidence of effectiveness， preceding communication channels with pharmaceutical companies， as well as exploring a price floor mechanism for the drugs with excessive price reduction.

Objective To investigate the effects of transcutaneous electrical acupoint stimulation at Neiguan combined with Danzhong on intraoperative remifentanil dosage and early postoperative pain in pa-tients undergoing radical mastectomy.Methods A total of 153 female patients undergoing radical mastecto-my under general anaesthesia aged 18-64 years,BMI 18.5-30.0 kg/m2 and ASA physical status Ⅰ or Ⅱwere enrolled.The patients were randomly assigned into three groups:single-acupoint(Neiguan)group,dual-acupoint(Neiguan and Danzhong)group and control group,51 patients in each group.TEAS for 30 minutes at different points(Neiguan combined with Danzhong for the dual-acupoint group,Neiguan for the single-acupoint group,no stimulation for the sham group)were given before anaesthesia induction.30 mi-nutes of disperse/dense stimulation of 2/10 Hz with an intensity of 4-11 mA was used.The consumption of remifentanil,time to recall and to extubation were recorded.The visual analogue scale(VAS)pain score in PACU and 24 hours after surgery,and patient satisfaction scores was recorded.Results The intra-operative remifentanil consumption in the dual-acupoint group was significantly less than groups single-acupoint and sham(P＜0.05).Patient satisfaction score 24 hours after surgery was significantly higher in the dual-acu-point group than those in groups single-acupoint and sham(P＜0.05).The VAS scores in PACU and 24 hours after surgery had no significantly differences among the three groups.Conclusion Compared with single-acupoint,stimulation at Neiguan combined with Danzhong in patients undergoing radical mastectomy induced stronger remifentanil-sparing effect and higher patients'satisfaction after radical mastectomy.

Within traditional teaching models,students frequently assume a passive role in acquiring knowledge,potentially resulting in diminished motivation and limited engagement,particularly within the realm of Medical Immunology education.The inte-gration of role-playing,informed by constructivist learning theory,situated learning theory,and multiple intelligences theory,has demonstrated encouraging outcomes within clinical medical education settings.However,the extent to which this approach has been explored within the context of Immunology instruction remains insufficiently examined.This study investigates the utilization of role-playing as a pedagogical approach in Medical Immunology education,wherein students are assigned specific scenarios to simulate the functions of various immune components.The primary objective is to augment interactivity and the overall appeal of the learning pro-cess.Efficacy of this instructional method was evaluated through in-class quizzes,surveys,and performance analysis.The findings demonstrate that role-playing substantially enhances student engagement,comprehension,knowledge retention,and examination per-formance.In practical application,the integration of role-playing with ideological and political elements has the potential to enhance learning outcomes and foster students'enthusiasm for engaging in cutting-edge literature and immunological research.This approach also necessitates greater proficiency in teachers'professional competencies and organizational skills,as well as increased allocation of class time and spatial resources.Future research should investigate the applicability of role-playing across various educational levels and examine its potential integration with classroom ideological and political education.

Objective Our study aimed to conduct genomic characterization of Salmonella strains carrying the b/aNDM-1 gene in the intestinal tract of healthy individuals.The objectives were to underscore the importance of genomic surveillance for drug resistance in both commensal and pathogenic bacteria among healthy populations,and to establish protocols for regulating drug resistance plasmids based on the completion of a comprehensive map of drug resistance plasmid genomes.Methods We performed antimicrobial susceptibility testing and employed second-and third-generation sequencing techniques to analyze Salmonella strains harboring the b/aNDM-1 gene,to surveil drug-resistant bacteria in the intestines of healthy subjects.Sequence comparison was conducted using both core-and pan-genome approaches.Concurrently,conjugation experiments were carried out to assess the efficiency of plasmid transfer.Results We isolated a carbapenem-resistant Salmonella enterica serovar Typhimurium strain from a healthy food worker in China.This strain harbored an lncHI2/lncHI2A plasmid carrying blaNDM-1 along with multiple antibiotic resistance genes(ARGs).Our findings highlight the potential for asymptomatic carriers to facilitate the transmission of ARGs.Pan-genomic analysis revealed that b/aNDM-1-positive plasmids could traverse bacterial species barriers,facilitating cross-host transmission.Conclusion This study marks the first detection of b/aNDM-1 in Salmonella strains isolated from healthy individuals.We underscore the risk associated with the transmission of conjugative hybrid plasmids carrying blaNDM-1,which have the potential to be harbored and transmitted among healthy individuals.Enhanced surveillance of drug-resistant pathogens and plasmids in the intestinal microbiota of healthy individuals could provide insights into the risk of ARG transmission and pathways for population-wide dissemination via ARG transfer factors.

Objective:To investigate the related factors of pleasure loss in patients with human immunodefi-ciency virus(HIV)/acquired immune deficiency syndrome(AIDS).Methods:Totally 237 patients with HIV/AIDS from a certain infectious disease hospital were selected and surveyed with a self-designed general information ques-tionnaire,the Temporal Pleasure Experience Scale(TEPS),Self Acceptance Scale(SAQ),Discrimination Percep-tion Scale(SIS),and Perceived Social Support Scale(PSSS).Results:The patient's TEPS score was(73.4±16.1).Stepwise linear regression analysis showed that the PSSS total scores,education level,and personal monthly income were positively correlated with the TEPS total scores(β=0.41,5.17,4.63),and age was negatively corre-lated with the TEPS total scores(β=-0.30).Conclusion:It suggests that more attention should be paid to the lack of pleasure in patients with HIV/AIDS,and the lack of pleasure is related to personal monthly income,educa-tion level,age and perceived social support.
