With the deepening of population aging， the number of disabled and semi-disabled elderly individuals continues to increase， and the ethical care issues of mental health services for the disabled elderly are becoming increasingly prominent. When examining ethical issues， the concept of the “holistic view of traditional Chinese medicine” from ancient Chinese traditional culture was explored. While applying theories from the holistic view of traditional Chinese medicine， such as “the unity of form and spirit” and “the integration of form and spirit，” emphasis should be placed on the organic integration of psychology and physiology. The mental health status of the disabled elderly can be comprehensively improved by addressing both internal and external environmental factors. In response to the current situation of mental health services for the disabled elderly， ethical care should be provided for the mental health services of the disabled elderly， focusing on the value of subjectivity， difference， and continuity in ethical care， thereby improving the mental health status of the disabled elderly.

Objective To investigate the growth, development and health status of primary and secondary school students in Xinzhou District of Wuhan, and analyze the detection and change trend of common diseases in primary and secondary school students, and to provide a basis for relevant departments to formulate prevention and control measures of common diseases in students. Methods The monitoring data of common diseases and health influencing factors of primary and secondary school students in Xinzhou District from 2019 to 2022 were analyzed and compared according to different genders, different grades and ages. SPSS 20.0 software was used to analyze the data of detection rates of myopia, dental caries, obesity, malnutrition and abnormal spinal curvature. Results The overall detection rates of myopia, dental caries, malnutrition, obesity and abnormal spinal curvature were 57.00%, 58.45%, 4.60%, 14.91%, and 6.33%, respectively, in Xinzhou District from 2019 to 2022. The annual change rates were 7.22%, 15.10%, -2.72%, 13.29%, and 4.91%, respectively. The detection rates of myopia, dental caries, obesity and abnormal spinal curvature showed an increasing trend in each year (χ² ≥17.22, P<0.001). The detection rates of myopia and malnutrition increased with the increase of age and school level (both χ²≥42.37, P<0.001), while the opposite was true for the detection rates of dental caries and obesity (both χ²≥14.26, P<0.001). The detection rates of myopia and dental caries were higher in girls than in boys (both χ²≥33.66, P<0.001), while the detection rates of obesity and abnormal spinal curvature were higher in boys than in girls (both χ²≥8.22, P<0.005). The detection rates of myopia, dental caries, obesity and abnormal spinal curvature in 2019 were lower than those in 2020-2022 (χ²≥4.11, P<0.05), while the detection rates of malnutrition had decreased. Conclusion The growth, development and health status of primary and secondary school students in Xinzhou District are serious. The detection rate of common diseases such as myopia, dental caries, obesity and abnormal curvature of the spine is on the rise, which should be the focus of the surveillance work of common diseases in primary and secondary school students in the future, and comprehensive intervention measures are urgently needed to prevent and control these common diseases.

BACKGROUND:Mesenchymal stem cells are susceptible to senescence during in vitro expansion,which greatly hinders their application in vivo and in vitro.How to improve the replicative senescence of mesenchymal stem cells is an urgent problem to be solved in tissue engineering. OBJECTIVE:To determine whether vascular endothelial growth factor combined with basic fibroblast growth factor can improve the aging of bone marrow mesenchymal stem cells caused by replicative passage. METHODS:Rat bone marrow mesenchymal stem cells were extracted by whole bone marrow adhesion method.Passage 2 cells were selected as normal control group.Passage 7 and later algebraic cells were selected as aging model group.Vascular endothelial growth factor(50 μg/L),basic fibroblast growth factor(10 μg/L),and their combination were administered.Cell proliferation was detected by CCK-8 assay.Cell senescence was observed by β-galactosidase activity staining.Cytoskeleton size and colony formation ability were observed by phalloidine staining and Giemsa staining,respectively,and the levels of senescence-related genes P16,P21,and P53 were detected by qRT-PCR.Gene expression levels of P16,P21,and P53 were tested by qRT-PCR. RESULTS AND CONCLUSION:(1)Vascular endothelial growth factor combined with basic fibroblast growth factor could promote the proliferation of aged bone marrow mesenchymal stem cells,which began to enter the plateau stage on day 9,and the absorbance value of the combined intervention group was significantly higher than that of the model group on day 9(P<0.05).(2)The phenotypic markers of the cells in the combined intervention group did not change,and the cell morphology changed from broad to slender.(3)Compared with the model group,the positive rate of β-galactosidase was significantly decreased(P<0.01);the number of nuclei increased(P<0.001);the total area of cytoskeleton increased(P<0.01);colony formation ability was enhanced(P<0.05);expression level of P16 was decreased(P<0.01)in the combined intervention group.These results indicate that vascular endothelial growth factor combined with basic fibroblast growth factor can improve the senescence of bone marrow mesenchymal stem cells caused by replicative passage without changing the cell phenotype.

Objective To establish a macrophage-specific KLF2 gene knockout mouse model,and explore the regulatory effect of KLF2 on the macrophage inflammatory response.Methods KLF2flox/+mice were constructed using CRISPR/Cas9 gene editing technology.Target genotype mice were obtained by breeding with Lyz2-Cre+/+mice and screening genotypes through polymerase chain reaction,and KLF2 knockout efficiency was verified using genotyping,qRT-PCR,and Western Blot.Bone marrow-derived macrophages(BMDMs)were isolated and cultivated and mRNA levels of inflammation-related factors in lipopolysaccharide-induced BMDMs were detected.Results A KLF2flox/flox/Lyz2-Cre+mouse model was established.KLF2 mRNA and protein levels in mouse bone marrow and BMDMs were significantly lower in KLF2 knockout mice compared with the findings in control mice,while expression levels of KLF2 in the heart,liver,and kidney showed no significant changes compared with levels in the control group.There were no significant differences in body weight,diet,drinking water,and appearance between the two groups.The group receiving lipopolysaccharide stimulation showed significantly reduced interleukin(IL)-6 mRNA expression and significantly increased IL-1,iNOS,and CD86 mRNA expression in KLF2-deficient BMDMs compared with the control group.Conclusions We constructed a macrophage-specific KLF2 knockout mouse model,thus laying the foundation for further research on the regulatory effect and mechanism of macrophage KLF2 in clinical inflammatory-related diseases.

Objective To analyze the characteristics of imported malaria epidemic from overseas in Wuhan, to explore the management mechanism of on-site cases, and to accumulate experience for the treatment of imported malaria in large cities after malaria elimination. Methods The epidemiological data on imported malaria from abroad during the period of malaria elimination (2010-2019) in Wuhan were collected. The gender, age and severe illness-related factors of the cases were analyzed. Based on the characteristics of the epidemic and the current situation of prevention and control, the content and experience of the “Municipal-District 24-7” case mechanism were discussed. Results The medical resources in Wuhan were the best in the central region, resulting in a large number of imported malaria cases, with a total of 474 cases reported from 2010 to 2019 (40.79% of the total number of cases in Hubei Province), including 359 cases of falciparum malaria, 36 severe cases and one death (the death rate was 0.28%). The patients were mainly young and middle-aged men aged 20 to 49 years old (97.26%). There were many referral cases (40.30%), and there was no seasonal clustering of cases reported. The undiagnosed proportion at the first visit was 44.85%, and the time of attack-diagnosis was 4 days or more in 61.00% of cases. The occurrence of severe cases was related to unconfirmed diagnosis at the first visit (χ²=35.46, P<0.001) and attack-diagnosis time (Z=-6.49, P<0.001). Conclusion Imported malaria occurs frequently in Wuhan, mainly falciparum malaria. However, “Municipal-District 24-7” case mechanism has effectively curbed the occurrence of severe and death cases and provided valuable experience for case management in similar cities in China.

OBJECTIVE: To investigate the effects of the B7-H4 gene rs10754339 and miR-125a gene rs12976445 on cancer susceptibility through a case-control study and meta-analysis. METHODS: A total of 1,490 cancer patients (lung/gastric/liver/: 550/460/480) and 800 controls were recruited in this case-control study. The meta-analysis was performed by pooling the data from previous related studies and the present study. RESULTS: The results of this study showed that in the Hubei Han Chinese population, the rs10754339 gene was significantly associated with the risk of lung and gastric cancer but not liver cancer, and the rs12976445 gene was significantly associated with the risk of lung cancer but not liver or gastric cancer. The meta-analysis results indicated that rs10754339 and rs12976445 contributed to cancer susceptibility in the Chinese population and also revealed a significant association between rs10754339 and breast cancer risk, as well as between rs12976445 and lung cancer risk. CONCLUSION The B7-H4 gene rs10754339 and miR-125a gene rs12976445 may be the potential genetic markers for cancer susceptibility in the Chinese population, which should be validated in future studies with larger sample sizes in other ethnic populations.

On December 20, 2018, a 40-year-old male patient with extremely severe flame burn was admitted to Guangzhou First People's Hospital. A variety of difficult illnesses occurred simultaneously (refractory hyperglycemia, refractory hypernatremia, and progressive wound deepening) and successively (repeatedly postoperative hypotension, nervous system diseases, and secondary diabetes insipidus). The patient underwent treatments such as anti-shock, reducing blood sugar and blood sodium, scab removing, and gradual skin grafting after admission. Although the hyperglycemia and hypernatremia were basically corrected and the wounds were basically repaired, the patient ultimately died of nervous system diseases and secondary diabetes insipidus 5 months later. Although the cause of the above illnesses can not be fully determined, the targeted treatments to improve clinical symptoms, maintain stable internal environment and physiological function, and accelerate the process of wound repair conducted by the team may provide some experience for the treatment of such severe patients.
