Objective:To construct a meridian tapping exercise program for frail elderly, so as to provide daily healthcare options for frail elderly people.Methods:Guided by the theory of meridians and collaterals, data mining was conducted on the database of ancient Chinese medical literature to select acupoints and meridians for tapping. Through literature research, the exercise prescription was improved. A preliminary exercise prescription was formulated through literature review and revised through two rounds of expert consultation in December 2023.Results:The effective response rate for both rounds of expert consultation questionnaires was 7/7. The expert authority coefficients were 0.83 and 0.87, respectively, and the overall Kendall′s coefficient of concordance was 0.301 and 0.302 (both P<0.05). The final meridian tapping exercise for frail elderly comprised 2 primary indicators, 8 secondary indicators, and 23 tertiary indicators. Conclusions:The meridian tapping exercise for the frail elderly is scientific, reliable and practical, which can provide a choice for the frail elderly to carry out targeted traditional Chinese medicine exercises.

Objective:This study aims to investigate the impact of socioeconomic status on cognitive function in older adults, while analyzing the mediating role of health-related social determinants.The findings will provide a foundation for the implementation of an active aging strategy.Methods:Utilizing data from the China Health and Retirement Longitudinal Study(CHARLS)2020, this study employed multiple linear regression analysis to investigate the relationship between socioeconomic status and cognitive function among older adults.A multiple mediation model was applied to evaluate the mediating effects of health-related social determinants on the association between socioeconomic status and cognitive function, with these mediation effects assessed using the Bootstrap method.Results:The results of the multiple linear regression analysis indicated that socioeconomic status significantly positively influences cognitive function in older adults.Factors such as younger age, male gender, Han ethnicity, and urban residence were associated with higher cognitive scores.The mediation analysis demonstrated that, of the total effect of socioeconomic status on cognitive function, health status accounted for 1.564%, individual lifestyle for 14.820%, social support networks for 2.719%, living conditions for 1.632%, and other social structural factors for 1.496%.In the multiple mediation model, a total of 17.945% of the effect of socioeconomic status on cognitive function in older adults was jointly mediated by health-related social determinants.Conclusions:Socioeconomic status is a critical determinant of cognitive impairment among older adults in China.To address this issue, comprehensive interventions should be implemented to promote the equitable distribution of economic and social resources, reduce socioeconomic disparities, and mitigate health inequalities, thereby enhancing the overall cognitive function of disadvantaged groups.Preventive measures and strategies aimed at improving health status, encouraging healthy lifestyle choices, strengthening social support networks, enhancing living conditions, and optimizing social structural factors could serve as essential intervention points to improve the cognitive function of older adults with lower socioeconomic status.

Objective: To explore the association between greenness surrounding school and aggression among primary school students, and to explore the potential mediating roles of social support, loneliness, particulate matter (PM2.5) and Nitrogen Dioxide (NO2) in this association, in order to provide a scientific reference for preventing and ameliorating aggressive behaviors of primary school students. Methods: The data was used from a survey of children and adolescents conducted in 2015. The Chinese version of the Buss-Warren Aggression Questionnaire was used to assess total and subtypes of aggression, and the mean values of normalized difference vegetation index (NDVI) of 100 m, 500 m, 1 000 m circular buffers surrounding school were used to indicate the participants greenness exposure. PM2.5 and NO2 datas were obtained from the China High Air Pollutants Dataset.Generalized Linear Mixed Models were used to assess the associations of greenness surrounding school with total and subtypes of aggression. Results: Per IQR increment of NDVI-500 m [OR(95%CI)=1.09(1.03-1.15)] and NDVI-1 000 m[OR(95%CI)=1.07(1.02-1.13)] were positively correlated with physical aggression among primary school children, and per IQR increment of NDVI-100 m [OR(95%CI)=0.94(0.90-0.99)], NDVI-500 m [OR(95%CI)=0.93(0.89-0.98)] and NDVI-1 000 m [OR(95%CI)=0.95(0.91-1.00)] were negatively associated with verbal aggression (P<0.05). Mediation analyses revealed that social support partially mediated the association between the NDVI-500 m and physical aggression (mediation ratio:18.0%) and verbal aggression (mediation ratio:-8.3%) among primary school students, and loneliness partially mediated the association between the NDVI-500 m and physical aggression and verbal aggression among elementary school students effects, with proportion mediated ratios of -10.0% and 21.0%, respectively (P<0.05). Conclusions Exposure to school surrounding greenness is likely to associated with physical aggression and verbal aggression in primary school students, and social support and loneliness may partially mediate these associations.

Objective To understand the current status of research on lung cancer immunotherapy to provide a reference for further investigation and future topic selection in this field. Methods CiteSpace visualization analysis software was used to analyze 400 Chinese studies in CNKI and 5 001 English studies in the Web of Science database from 2005 to 2021, with "lung cancer" and "immunotherapy" as keywords. Keyword co-occurrence analysis was performed on 17 English studies of "Lung Cancer" "Immunotherapy" and "Single cell sequencing" in the Web of Science database. Results "Non-small cell lung cancer" "immunosuppressants" "PD-L1" "dendritic cells" and "cytokine-induced killer cells" are current research hotspots in lung cancer immunotherapy. Monoclonal antibody drugs including nivolumab, pembrolizumab, atezolizumab, and durvalumab are hotspot drugs. Immunotherapy combined with chemotherapy as well as PD-L1 expression have become the focus of continuous research. The majority of studies on lung cancer immunotherapy are conducted in the United States, followed by China. Conclusion Lung cancer immunotherapy has gradually become a research hot spot in China. In the future, in-depth research is needed to provide cutting-edge directions for lung cancer immunotherapy.

Objective:To explore the change in cerebral blood flow when healthy subjects swallow hot and ice water, and to verify the sensitivity of functional near-infrared spectroscopy (fNIRS) in identifying liquid temperatures while swallowing as a basis for applying it in diagnosis and intervention.Methods:Sixteen healthy subjects swallowed hot and ice water in randomized order while the process was recorded using fNIRS. The activation at rest and when swallowing hot and ice water was compared pairwise.Results:Compared with the resting state, 19 channels were activated during the swallowing of the hot and ice water. The common activated areas were S1, M1, PMC, SMA, Wernicke′s area, the somatosensory association cortex, the visual association cortex and the frontal eye field. However, the dorsal lateral prefrontal cortex was activated only when swallowing hot water, and the subcentral area was activated only when swallowing ice water. The SMA and PMC were significantly more activated when swallowing hot water than ice water.Conclusions:Multiple brain regions are activated and participate in regulating swallowing. The PMC and SMA areas can distinguish hot water from ice water swallowing.

ObjectiveTo explore the underlying mechanism of Bushen Huatan prescription in alleviating postmenopausal osteoporosis （PMOP） by maintaining the balance of osteogenesis and adipogenic differentiation in ovariectomized rats with osteoporosis. MethodSeventy-five 6-month-old non-pregnant female SD rats were randomly divided into sham-operation group， model group， atorvastatin group， liviol group， and Bushen Huatan prescription group. Bilateral ovaries were removed in the four groups except the sham-operation group， while only the same mass of adipose tissue around the ovaries was removed in the sham-operation group. On the 5^th week after surgery， drugs were consecutively administrated for 8 weeks. Rats in the Bushen Huatan prescription group received 9.4 mg·kg^-1 of the prescription， rats in the atorvastatin group received 0.92 mg·kg^-1 of atorvastatin， rats in the Liviol group received 0.23 mg·kg^-1 of liviol， and rats in the model group and the sham-operation group received saline once a day. Micro-computed tomography （Micro CT） was used to detect bone mineral density （BMD） of rat tibia in each group. Hematoxylin-eosin （HE） staining was used to detect the relative area of rat bone marrow adipose tissue （BMAT） in each group. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the relative expression levels of Runt-related transcription factor 2 （Runx2）， peroxisome proliferator-activated receptor （PPARγ）， leptin （LPN）， and leptin receptor （OBR） in bone tissues. ResultAs compared with the sham operation group， the BMD of rats in the model group decreased （P<0.05）， while the relative area of BMAT increased （P<0.05）. In addition， the expression levels of LPN， OBR， and Runx2 decreased in the model group （P<0.05）， while the level of PPARγ increased （P<0.05）. As compared with the model group， the BMD of rats in the atorvastatin group， the Livial group， and the Bushen Huatan prescription group increased （P<0.05）， and the relative area of BMAT decreased （P<0.05）. The expression levels of LPN， OBR， and Runx2 in these groups increased （P<0.05）， while the expression level of PPARγ decreased （P<0.05）. ConclusionBushen Huatan prescription plays the anti-osteoporosis role in the rat model of PMOP through up-regulating LPN and OBR in bone tissues and maintaining the balance of osteogenesis and adipogenic differentiation， thereby reducing postmenopausal bone loss and playing a role in the prevention and treatment of PMOP.

Objective To investigate the effect of CYP2D6 gene polymorphism on risperidone (RISP) metabolism in schizophrenic patients. Methods CYP2D6 allele polymorphisms including*10,*4,*41 and *2 was detected by real-time fluorescent PCR in 120 schizophrenic patients who have taken risperidone continually. Alleles without SNP mutations were classified as wild-type (WT). At the same time, serum risperidone and 9-hydroxyrisperidone concentration of all patients were detected by mass spectrometric analysis. Some samples were selected for DNA sequencing of CYP2D6*10, which is the most common CYP2D6 allele in Oriental population. The 120 patients were divided into three groups according to their allele variants. Group 1 was defined as carriers of two functional alleles, group 2 was defined as carriers of one defective allele, group 3 was defined as carriers of two defective alleles. Genotype distributions, alleles frequencies, RISP, 9-oh-RISP, RISP+9-OH-RISP, 9-oh-RISP/RISP among three groups were calculated.Results Group 1 amount to 23 cases including 13 cases of WT/WT, 7 cases of*2/*2, 3 cases of WT/*2. Group 2 amount to 51 cases, including 38 cases of WT/*10, 8 cases of *2/*10, 1 case of *2/*41, 4 cases of WT/*41. Group 3 amount to 46 cases, including 44 cases of *10/*10, 2 cases of *10/*41. The*4 allele was not detected. The allele frequency of WT, *2, *10 and *41 was 29.6％, 10.8％, 56.7％ and 2.9％, respectively. The 9-hydroxyrisperidone/risperidone-ratio of three groups were 15.24±5.77, 11.06±4.56 and 2.39 ± 1.06, respectively. There was a significant difference in 9-hydroxyrisperidone/risperidone-ratio between Group 3 and the first two groups (P<0.001). Conclusions The frequency of *10 allele was the highest among the subjects. The frequency of WT and*2 allele was over 95％in the population. Individuals carrying one defective allele of CYP2D6 will decrease the rate of risperidone metabolism slightly, while individuals carrying two defective alleles of CYP2D6 may decrease the rate of risperidone metabolism significantly.
