Objective: To investigate the health literacy level and its influencing factors among the elderly in nursing homes in Xiangshan County, Zhejiang Province, so as to provide the reference for improving the health literacy of the elderly in nursing homes. Methods: In September to November 2024, elderly individuals aged ≥60 years from nursing homes in Xiangshan County were selected by a stratified random sampling method. Data on basic information and health literacy were collected using the Chinese Elderly Health Literacy Questionnaire. The health literacy level of the elderly in nursing homes was analyzed. The influencing factors of their health literacy level was analyzed using a multivariable logistic regression model. Results: Among the surveyed participants, there were 265 males (41.09%) and 380 females (58.91%). The median age was 83.00 (interquartile range, 12.00) years. A total of 42 individuals had health literacy, giving a health literacy level of 6.51%. The health literacy levels of basic concepts, basic skills and basic knowledge were 15.04%, 15.04% and 5.74%, respectively. The health literacy levels of health service utilization and chronic disease management, scientific view of aging, information acquisition and self-care, healthy lifestyle, intrinsic capacity and geriatric syndromes, and safety and first aid, were 49.15%, 39.22%, 24.81%, 20.78%, 11.63% and 1.71%, respectively. Multivariable logistic regression analysis showed that gender (female, OR=3.720, 95%CI: 1.687-8.203), age (70-<80 years old, OR=0.084, 95%CI: 0.016-0.428), educational level (junior high school, OR=5.690, 95%CI: 1.433-22.600; senior high school/vocational high school/technical secondary school and above, OR=14.620, 95%CI: 3.321-64.361), marital status (unmarried/divorced/widowed, OR=0.263, 95%CI: 0.122-0.567), and personal monthly income (1 000-<3 500 yuan, OR=0.136, 95%CI: 0.024-0.763) were factors affecting the health literacy level of the elderly in nursing homes. Conclusions The health literacy level among the elderly in nursing homes in Xiangshan County are relative low in terms of basic knowledge, intrinsic capacity and geriatric syndromes, and safety and first aid. Gender, age, educational level, marital status, and monthly income are influencing factors for health literacy level among the elderly in nursing homes.

Traditional Chinese medicine formula (TCMF) represents a fundamental component of Chinese medical practice, incorporating medical knowledge and practices from both Han Chinese and various ethnic minorities, while providing comprehensive insights into health and disease. The foundation of TCMF lies in its holistic approach, manifested through herbal compatibility theory, which has emerged from extensive clinical experience and evolved into a highly refined knowledge system. Within this framework, Chinese herbal medicines exhibit intricated characteristics, including multi-component interactions, diverse target sites, and varied biological pathways. These complexities pose significant challenges for understanding their molecular mechanisms. Contemporary advances in artificial intelligence (AI) are reshaping research in traditional Chinese medicine (TCM), offering immense potential to transform our understanding of the molecular mechanisms underlying TCMFs. This review explores the application of AI in uncovering these mechanisms, highlighting its role in compound absorption, distribution, metabolism, and excretion (ADME) prediction, molecular target identification, compound and target synergy recognition, pharmacological mechanisms exploration, and herbal formula optimization. Furthermore, the review discusses the challenges and opportunities in AI-assisted research on TCMF molecular mechanisms, promoting the modernization and globalization of TCM.

Objective:To investigate the effect of bilateral globus pallidus internus deep brain stimulation (GPi-DBS) on motor performance, quality of life, sleep quality, neuropsychological status, and mood in patients with Meige syndrome.Methods:The clinical data of 17 patients with Meige syndrome accepted bilateral GPi-DBS in Department of Neurosurgery, People's Hospital of Peking University from May 2019 to March 2021 were retrospectively analyzed. Established and validated rating scales were used to assess the motor performance, quality of life, sleep quality, neuropsychological status, and mood at baseline, and 1 and 2 years after GPi-DBS.Results:Burke-Fahn-Marsden dystonia rating scale (BFMDRS) motor total scores decreased from 14.4±6.2 at baseline to 4.3±2.2 and 3.5±1.9 at 1 and 2 years after GPi-DBS, with significant differences ( P<0.05). BFMDRS disability total scores decreased from 6.2±4.0 at baseline to 2.8±2.0 and 2.2±1.5 at 1 and 2 years after GPi-DBS, with significant differences ( P<0.05). In 36-item Short-Form Health Survey (SF-36), the scores of physical function, role-physical, general health sub-items at 1 and 2 years after GPi-DBS were significantly higher than those at baseline ( P<0.05). No significant differences were noted in scores of sleep quality, neuropsychological function, or mood scales at 1 and 2 years after GPi-DBS compared with those at baseline ( P>0.05). Conclusion:Bilateral GPi-DBS is effective and safe in Meige syndrome, which can improve dystonic symptom and quality of life without adverse effects on sleep quality, neuropsychological function, or emotional status.

Objective:To explore the pathogenesis of glossopharyngeal neuralgia (GPN) in central nervous system from perspective of brain morphology.Methods:A prospective study was performed. Twenty-seven patients with right primary GPN admitted to Department of Neurosurgery, People's Hospital of Peking University from April 2019 to June 2023 and 27 healthy subjects (controls) matched with age, gender, dominant hand, and education level during the same period were recruited. These patients were divided into GPN with neurovascular compression group ( n=18) and GPN without neurovascular compression ( n=9) based on intraoperative presence of neurovascular compression. SPM8 software based on Matlab R2017b programming platform and VBM8 toolbox were used to process the whole-brain high-resolution 3D-T1 brain structural image data of the participants and analyze the differences in the gray matter volume of each brain region between the 2 groups. Pearson correlation was applied to analyze the correlations of gray matter volumes in brain regions enjoying significant difference with baseline data and pain characteristics of these GPN patients. Results:Compared with controls, patients with GPN had significantly reduced gray matter volumes in the left anterior cingulate gyrus, middle temporal gyrus, transverse temporal gyrus, precentral gyrus, postcentral gyrus, right insula, thalamus, inferior parietal lobule, precentral gyrus, middle temporal gyrus, and inferior temporal gyrus ( P<0.05, FDR corrected). Compared with GPN patients with neurovascular compression, GPN patients without neurovascular compression had significantly reduced gray matter volume in the bilateral anterior cingulate gyrus ( P<0.05, FDR corrected). Changes of gray matter volume in the right insula were negatively correlated with disease duration of GPN patients ( r=-0.521, P=0.005). Conclusion:GPN patients have extensive gray matter atrophy in the brain, which may play an essential role in GPN development and maintenance.

There were 11 852 males and 1 411 females, aged from 18 to 102 years, with a median age of 64 years. Of 13 263 patients, 9 995 with compression treatment after tension-free inguinal hernia repair were divided into compression group and 3 268 without compression treatment after tension-free inguinal hernia repair were divided into non-compression group. Observation indicators: (1) compression treatment of patients in the compression group; (2) occurrence of VTE after tension-free inguinal hernia repair in the two groups; (3) analysis of influencing factors for VTE after tension-free inguinal hernia repair. Follow-up using telephone interview was performed to detect history of patient's thrombosis, medical history of patient's family and the incidence of postoperative VTE up to February 2018. Measurement data with skewed distribution were represented as M ( P25, P75) or M (range), and comparison between groups was analyzed using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis and multivariate analysis were conducted using the Logistic regression model. Results:(1) Compression treatment of patients in the compression group: of the 9 995 patients in the compression group, 6 086 underwent compression treatment with 0.5 kg of sandbag or 500 mL of packed 0.9% sodium chloride solution, 1 881 underwent compression treatment with trusses, 745 underwent compression treatment with girdles, 675 underwent compression treatment with elastic underwear combined with 0.5 kg of sandbag, and 608 underwent compression treatment with elastic underwear. (2) Occurrence of VTE after tension-free inguinal hernia repair in the two groups: patients of the two groups after matching were followed up. Occurrence of VTE after matching were 15 and 1 in the compression group and non-compression group, respectively, showing no significant difference between the two groups ( χ2=2.010, P>0.05). (3) Analysis of influencing factors for VTE after tension-free inguinal hernia repair: results of univariate analysis showed that cases with varix of lower limb, cases with oral contracep-tives or hormone replacement therapy history, cases with VTE history, clinical classification, clinical typing, surgical method, cases with anticoagulant drugs history, cases undergoing oral antiplatelet drugs, cases undergoing postoperative VTE prevention with medication were related factors for occurrence of VTE after tension-free inguinal hernia repair ( odds ratio=13.98, 37.71, 19.21, 4.43, 4.21, 0.07, 0.08, 0.10, 31.04, 95% confidence interval: 3.15?62.11, 8.35?170.24, 6.15?60.00, 1.43?13.76, 1.20?14.82, 0.01?0.49, 0.02?0.27, 0.04?0.29, 8.53?112.93, P<0.05). Results of multivariate analysis showed that cases with VTE history and surgical method were independent influencing factors for occurrence of VTE after tension-free inguinal hernia repair ( odds ratio=7.78, 11.19, 95% confidence interval: 2.06?29.42, 1.45?86.55, P<0.05).

Objective:To explore the risk factors of lymph node metastasis and prognosis in Siewert Ⅱ/Ⅲ adenocarcinoma of esophagogastric junction (AEG) patients.Methods:A total of 134 patients who underwent surgical operation between June 2013 and December 2019 at the Beijing Friendship Hospital, Capital Medical University were retrospectively reviewed, including 112 males and 22 females, with a male to female ratio of 5.5∶1 and an average age of 62.1(27-82 years old). The primary outcomes were lymph node metastasis risk and 3-years overall survival. The secondary outcomes were the rate and pattern of lymph node metastasis. Follow-up methods mainly include outpatient and telephone. During the follow-up period, the patient needs to receive physical examination, laboratory examinations, chest and abdominal CT scan and gastroscopy to evaluate the status of disease. The patients were followed up until January 2020. Chi-square test or Fisher test was used for the comparison between count data group, and rank sum test was used for the comparison between grade data group. Stepwise Logistic regression was used for multivariate analysis, and COX regression risk model was used for survival analysis.Results:Multivariate analysis revealed that the parameters infiltration depth ( OR=4.341, 95% CI: 2.498-7.545, P=0.000), gross type ( OR=3.626, 95% CI: 1.425-9.228, P=0.007) and intravascular cancer embolus ( OR=2.888, 95% CI: 1.106-7.544, P=0.030) correlated with lymph node metastasis. For all patients, the lymph nodes No. 1, 2, 3, 4, 7, 11 indicated higher lymph node metastatic rate in the abdominal cavity. However, No.5 and No. 6 indicated different tendency, which was higher in Siewert Ⅲ AEG and lower in Siewert Ⅱ AEG patients. Mediastinal lymph node metastasis of Siewert Ⅱ AEG mainly occurred in No. 110 and No. 111 cases corresponding to 7.1 and 3.0%, respectively, compared with those noted in Siewert Ⅲ AEG patients. The 3-year overall survival analysis revealed that lymph node metastasis (82.1% vs 46.1%, P=0.046) and chemotherapy (60.6% vs 39.4%, P=0.007) exhibited significant differences. Conclusions:The infiltration depth, gross type and intravascular cancer embolus are independent risk factors of lymph node metastasis. In addition, patients with lymph node metastasis exhibite worse long-term prognosis. The data indicate that perioperative chemotherapy could improve the prognosis of AEG patients.

ObjectiveTo evaluate the safety and effectiveness of fast track surgery (FTS) in l aparoscopy-assisted radical distal gastrectomy (LADG) for gastric cancer.MethodsSixty-one patientswith distal gastric cancer were randomly divided into three groups:FTS + LADG group (n =19) undergoing LADG and FTS treatments,LADG group (n =22) undergoing LADG and traditional perioperative cares,and FTS + ODG ( open distal gastrectomy) group ( n =21 ) undergoing ODG and FTS treatments.FTS treatments included avoidance of mechanical bowel cleansing,restrictive perioperative intravenous infusion,early ambulation,early enteral nutrition.The age,sex,body weight,anastomotic mode,number of lymph node dissected,and tumor stage,serum albumin (ALB),blood urea nitrogen (BUN),C-reaction protein (CRP),flatus time,postoperative hospital stay,medical cost,and postoperative complications were compared between three groups. ResultsThe level of ALB in FTS + LADG group were higher than in LADG group at the 4th and 7th day after surgery ( P ＜ 0.05,P ＜ 0.01 ).Compared to LADG group,the variation of ALB from preoperation to 4th day after surgery in FTS + LADG group and FTS + ODG group was significant( P ＜ 0.01,P ＜ 0.05 ).CRP level between FTS + LADG group and FTS + ODG group were different significantly at 4th and 7th day after surgery ( P ＜ 0.05,P ＜ 0.05).FTS + LADG group has earlier recovery of gastrointestinal peristalsis than other two groups ( P ＜ 0.05,P ＜ 0.05 ).The medical cost in FTS + LADG group was less than in LADG group ( P =0.003 ),but higher than in FTS + ODG group (P ＜0.01 ).ConclusionsThe practice of FTS in LADG was safe,effective,improves nutritional status,eases stress reaction,accelerates gastrointestinal peristalsis and postoperative rehabilitation.

OBJECTIVEThe purpose of this study was investigate the effect of hyperthemia on multidrug resistance in K562/ADM cell.

METHODSThe MDR1 (mulitdrug resistance gene) and MRP (multidrug resistant associated gene) gene expressions in Tca8113 and K562/ADM cell lines were analyzed by RT-PCR after treated with different cytotoxic drugs and different temperature (37 degrees C and 41 degrees C). The function and expression of Pgp and MRP were detected by fluorescence photometeric assays.

RESULTSInhibition rate of both cells was significantly enhanced by exposure to chemotherapeutic drugs and 41 degrees C temperature; Exposing to 41 degrees C hyperthemia reduced MDR1 and MRP expression and enhanced intracellular drug concentration as well in K562/ADM.

CONCLUSION41 degrees C hyperthemia could effectively enhance the inhibition rate of chemotherapeutic drugs and partially reverse the multidrug resistance. It is suggested that hyperthemia could be used as a method to overcome multidrug resistance.
