This study was aimed at analyzing the epidemiological and drug resistance characteristics of tuberculosis at a desig-nated tuberculosis hospital in Hunan Province in 2024.Patients diagnosed with TB at the hospital between April and October 2024 were included in the study.Demographic data,clinical information,and drug sensitivity test results were collected from the hospital′s electronic medical record system.Descriptive statistics,the chi-square test,and logistic regression were used to analyze the epidemic characteristics,drug resistance characteristics,and factors influencing tuberculosis.Whole genome sequencing of isolates was per-formed,and lineage classification and drug resistance gene mutations were detected with TB-Profiler.The male-to-female ratio was 2.72∶1,and the median age was 56(IQR:43-66)years.Among the 391 patients,most were farmers(46.8%,183/391)and were pri-marily from Changsha(41.1%,162/391).Significant differences were observed in sex and occupation between pulmonary tuberculosis(PTB)and extrapulmonary tuberculosis(EPTB).The overall prevalence of any type of drug resistance of tuberculosis was 33.25%,and the multidrug resistance TB(MDR-TB)and poly-drug resistance(PR-TB)rates were 14.23%and 4.35%,respectively.The re-sistance rates to rifampicin(RIF),isoniazid(INH),ethambutol(EMB),and streptomycin(SM)were 17.90%,22.25%,6.39%,and 20.20%,respectively.Multivariable logistic regression analysis indicated that both diabetes(OR:2.295,95%CI:1.082-4.866)and retreatment(OR:17.822,95%CI:8.343-38.072)were risk factors for developing MDR-TB.Lineage 2(L2)strains accounted for 64.40%(136/191),whereas lineage 4(L4)accounted for 28.80%(55/191).The most common drug resistance mutations were katG Ser315Thr(62.50%,20/32)for INH,rpoB Ser450Leu(50.00%,12/24)for RIF,embB Met306Val(55.56%,5/9)for EMB,and rpsL Lys43Arg(80.95%,34/42)for SM.In conclusion,TB drug resistance was found to be a serious problem at a designated tu-berculosis hospital in Hunan in 2024.Strengthening the treatment and management of patients infected with L2 strains,those with co-morbid diabetes,and retreatment cases is crucial for preventing and controlling the emergence of drug-resistant TB.

Objective:To investigate the status and influencing factors of quality of life among disabled elderly whose home care services were paid by the long-term care insurance in Guangzhou, in order to provide a scientific evidence for improving their quality of life and improving the long term care insurance system.Methods:A convenience sample of 161 disabled elderly whose home care services were paid by the long-term care insurance were recruited and investigated. A cross-sectional survey was conducted by general information questionnaire, World Health Organization Quality of Life Brief Scale, Barthel Index, Self-rating Depression Scale, Self-rating Anxiety Scale and World Health Organization Happiness Index Scale.Results:The score of the quality of life among disabled elderly was 41.17±7.79. And the score of its four dimensions in descending order: environment, social relationships, psychological and physical with (11.38 ± 2.71), (10.36 ± 3.16), (9.86 ± 2.08), (9.56 ± 1.89) points. The multiple linear regression analysis found that frequencies of outdoor activities per week, frequencies of hospitalization in the past year, subjective well-being, depression and anxiety influenced the quality of life of the disabled elderly( P<0.05). Conclusions:The quality of life of disabled elderly is not optimistic. Nurses in home care institutions should formulate personalized nursing intervention based on influencing factors to improve the quality of life of disabled elderly, while providing a basis for optimizing long-term care insurance policies.

Objective:To explore the real experience of family caregiver in providing care service and receiving home care organizational management after the disabled aged enjoyed the long-term care insurance so as to provide a scientific basis for standardizing the long-term care insurance home care service.Methods:From July to September 2019, this study selected 14 family caregivers of the home disabled aged enjoying the long-term care insurance in Guangzhou by purposive sampling to carry out the semi-structured interview so as to understand the personal feelings and suggestions of interviewees on long-term care insurance home care service. Colaizzi phenomenological analysis was used to data analysis.Results:A total of two themes were abstracted including the harvest of family caregiver and insufficient management model.Conclusions:Long-term care insurance home care service is instrumental in reducing the economic burden, care burden of family caregivers, and promoting the normative development of home care service. However, there is insufficient management model of family caregivers which needs to be improved.

Objective To explore the correlation between resilience and psychological status of main caregivers among disabled elderly of Guangzhou region.Methods From June 2015 to December 2015, a total of 300 main caregivers of disabled elders were investigated with the general information questionnaire, the Chinese version of Connor-Davidson Resilience Scale (CD-RISC), Activities Daily Living Scale (ADLS), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) by convenience sampling.Results The total score of resilience, standard score of anxiety and depression were (58.2±15.8), (49.05±10.5) and (51.73±11.52) respectively among main caregivers of disabled elders. The competence dimension of CD-RISC had negative correlations with anxiety (r=-0.260,P<0.01) and depression (r=-0.316,P<0.01) in main caregivers of disabled elders, and the toughness dimension was negatively correlated with the depressive symptoms (r=-0.147,P<0.05).Conclusions Main caregivers of disabled elderly of Guangzhou region are with poor resilience along with the high ratio of detection in anxiety and depression suggesting that the mental status is not optimistic.

Methods:The limit of detection, linearity, accu-racy, repeatability, recovery and content of Folin-Ciocalteu method and Coomassie brilliant blue binding method were investigated. Re-sults:As for Folin-Ciocalteu method, the limit of detection was 0. 2 μg, the range of linearity was 0-112. 0 μg(r=0. 9990), the av-erage recovery was 105. 2%(RSD=1. 9%), the RSD of accuracy was less than 1%, and the content result of three batches of samples was 47. 45, 58. 34 and 40. 99 μg·ml-1, respectively. As for Coomassie brilliant blue binding method, the limit of detection was 0. 8 μg, the range of linearity was 0-99. 6 μg(r=0. 9980), the average recovery was 102. 0%(RSD=2. 7%), the RSD of accuracy was less than 1%, and the protein content of samples was not detected out by the method. Conclusion:Folin-Ciocalteu method can be used to determine the protein content in mannatide oral solution reliably and efficiently.

Objective To study the value of the neuron-specific enolase(NSE) in the serum of patients with cerebral stroke in diagnosis, seriousness and evaluation of prognosis. Methods The levels of NSE in the serum of 77 patients with cerebral stroke(36 cases with hemorrhage, 41 cases with infarction) were measured by radio-immunoassay (RIA)method.Results The serum leves of NSE both in cerebral infarction and cerebral hemorrhage patients were obviously higher than those of the control group( P 0.05). In the first week there was a positive correlation between NSE serum level and neurological deficit scores,the volume of haemorrhage, the volume of infarction( P 0.05) . Conclusion The NSE level in serum may be served as a objective index of seriousness and early diagnosis in stroke, but no helpful in differential diagnosis and evaluation of prognosis.
