Objective:To assess the effects of various leisure hobbies on the ability of daily living(ADL)and the quality of life among older adults in China.Methods:A cross-sectional study was conducted using data from the 4th Chinese Urban and Rural Elderly Living Conditions Sample Survey.We categorized community recreation hobbies into two types: dynamic hobbies, which include walking, playing ball games, dancing, and other physical activities, and static hobbies, which encompass activities that do not require physical exertion, such as reading, watching TV, and drawing.The EuroQol five-dimension scale(EQ-5D)-3L was employed to evaluate the quality of life.Older adults who maintained either dynamic or static hobbies for three consecutive years from 2017 to 2019 were initially screened.The relationship between different types of leisure hobbies and ADL scores, as well as quality of life at various time points, was analyzed using repeated-measures ANOVA.Subsequently, propensity scores were matched based on gender, age, ethnicity, marital status, literacy, and chronic diseases, and five machine learning algorithms were utilized to identify the optimal model for predicting fully independent ADL and EQ-5D effect values.Based on the optimal predictive model, we conducted Shapley Additive Explanations(SHAP)and global analysis.Results:The total number of older adults who participated in the survey over the three consecutive years from 2017 to 2019 was 4 912.Among these, 2 594 individuals maintained the same hobby habits throughout this period, comprising 1 362 males and 1 232 females, with an average age of(70.81±6.71)years.Statistically significant differences in ADL scores and EQ-5D scores were observed between the dynamic and static leisure hobby groups(all P<0.05)across various time points, hobby group classifications, and interaction levels.Older adults engaged in dynamic hobbies exhibited superior ADL functioning and higher EQ-5D scores in comparison to those in the static hobby group, with these differences remaining statistically significant following propensity score matching(all P<0.05).In predicting full ADL independence, the SHAP value for dynamic hobbies ranked second, while for predicting an EQ-5D weighted value of 1, the SHAP value for dynamic hobbies ranked ninth.Overall, the type of dynamic hobby demonstrated a positive trend in its effect on the ability to perform daily activities independently and in achieving an EQ-5D weighted value of 1. Conclusions:In comparison to static hobbies, Chinese older adults who engage in dynamic hobbies exhibit improved daily mobility and a higher quality of life.Furthermore, dynamic hobbies positively influence the capacity for full independence in daily activities, as evidenced by an EQ-5D weighted value of 1.

Objective:To explore the differential diagnostic value of abdominal diffusion-weighted imaging (DWI) combined with serum alpha fetoprotein (AFP), des-gamma-carboxyprothrombin (DCP), and the ratio of γ-glutamyl transpeptidase to alanine transaminase (GTP/ALT) in the diagnosis of benign and malignant liver tumors.Methods:Ninety liver tumor patients admitted to the Chenzhou First People′s Hospital from February 2020 to May 2022 were selected, including 48 malignant tumors and 42 benign tumors, and were divided into malignant group and benign group. The imaging findings of routine magnetic resonance imaging (MRI) and DWI examination were analyzed for two groups of patients. We compared the apparent diffusion coefficient (ADC) values, serum AFP, DCP levels, and GTP/ALT between two groups of patients. The diagnostic value of DWI, individual and combined detection of various serological indicators for malignant tumors was analyzed using receiver operating characteristic (ROC) curves.Results:There were significant differences in MRI and DWI imaging manifestations between the malignant and benign groups of patients. The ADC values and ADC index of patients in the malignant group at different b values of 50, 400, and 800 s/mm 2 were lower than those in the benign group, and the differences were statistically significant (all P<0.05). The serum AFP, DCP, and GTP/ALT of patients in the malignant group were higher than those in the benign group, and the differences were statistically significant (all P<0.05). The ROC curve analysis results showed that the sensitivity and specificity of DWI combined with serum AFP, DCP, and GTP/ALT in diagnosing liver malignant tumors were higher than those of DWI alone and each serological indicator alone. Conclusions:The combination of DWI, serum AFP, DCP, and GTP/ALT has high sensitivity and specificity in diagnosing liver malignant tumors, and has certain clinical value in distinguishing between benign and malignant liver tumors.

Objective:To explore the effect of traditional teaching and standardized patient (SP) teaching in medical students' inquiry teaching through the phased examination results of practicing physicians.Methods:A total of 107 students from Class 1 and Class 2 of Batch 2013 majoring in clinical medicine of Qinghai University were selected as the control group, and 100 students from Class 1 and Class 2 of Batch 2014 were selected as the experimental group. In the inquiry teaching, the control group adopted the traditional teaching method, and the experimental group adopted the SP teaching method. The effect of the two groups of teaching methods was compared by collecting the scores of the medical history of the medical practitioners in the phased examination. SPSS 18.0 was used for t-test. Results:The scores of current medical history (81.43±8.19), case collection (8.19±0.70), inquiry content (47.63±4.55), examiner's total score (73.75±5.21), and total score (91.93±5.67) in the experimental group were higher than those in the control group [(71.65±8.29) (7.85±0.68) (43.68±4.76) (69.68±5.40) and (88.03±6.01)] and the difference was statistically significant ( P<0.001). The scores of communication ability (8.94±0.62) question expression (4.54±0.44) and communication skills (4.52±0.47) in the comprehensive performance of the control group were higher than those in the experimental group [(8.77±0.60) (4.33±0.54) and (4.38±0.46), respectively], and the difference was statistically significant ( P<0.05). Conclusion:The overall teaching effect of the SP teaching is better than that of the traditional teaching, but it has its own advantages and disadvantages in specific knowledge points. It is worth further discussion to combine the two to complement the advantages and complement each other to assist medical education.

Cystic echinococcosis is one of the most widespread and severe zoonotic helminthic diseases .To understand the phylogeny and genetic polymorphism Echinococcus granulosus (E .granulosus) prevailed in south region of Qinghai Prov-ince ,partial fragment of cytochrome oxidase Ⅰ (COX Ⅰ ) gene sequences were used to infer the phylogenetic relationship of 59 collected samples of E .granulosus in Qinghai Province .Total 72 sequences (13 sequences from GenBank) were aligned using CLUSTAL X ,and then ,Bayesian analyses were performed in Mrbayes-3 .1 .2 .The results revealed that Echinococcus spp .isolates did not form a monophyletic group .The most samples clustered with E . granulosus strain (G1) (AB297617) , but showed high genetic polymorphism .Another three samples clustered with E .multilocularis (AB018440) ,while they showed complex phylogenetic relationships among them ,further indicating that Echinococcus spp .isolates from Qinghai Prov-ince may has a more complex evolutionary history than expected .

To investigate the prevalence of specific anti-Toxocara IgG and IgE antibodies in ocular toxocariasis by means of ELISA and Western blotting, serum samples of 105 cases with uveitis of unidentified etiology were randomly selected from our stocked sera, which were referred to the Section of of Environmental Parasitology of Tokyo Medical and Dental University for detection of the anti-Toxocara antibody. By using ELISA, 82 of them (78.1%) were negative for both IgG and IgE antibodies, 12 (11.4%) were positive only for IgG, three (2.9%) were positive only for IgE, and eight (7.6%) were positive for IgG and IgE. Among the positive samples, as demonstrated by western bloting the IgG reacting bands were found to distribute in the whole range of molecular weights (97.2-14.3kDa)of excretory-secretory products of T. canis larvae. On the other hand,IgE antigenic molecules were concentrated on a relatively narrow range from 45kDa to 29kDa. In this study, we clearly demonstrated that some of the patients with uveitis showed specific anti-Toxocara IgE antibody but not IgG antibody in serum sample, suggesting that the demonstration of specific IgE antibody should be considered for the precise diagnosis of ocular toxocariasis. Further studies are needed to clarify the diagnosis significance of specific IgE antibody in ocular toxocariasis.
