Objective To retrospectively analyze the prevention and control effect and epidemic characteristics of elderly tuberculosis in Hubei Province from 2016 to 2020, and to provide a scientific basis for the prevention and treatment of elderly tuberculosis in Hubei Province． Methods The data on tuberculosis patients aged 60 and above who registered their current address in Hubei Province from 2016 to 2020 were collected and analyzed. The registration rates and composition ratios were analyzed using χ² test and χ² test for trend. Results A total of 135 976 tuberculosis patients were reported in Hubei from 2016 to 2020. The annual average registration rate of elderly tuberculosis among the elderly registered residence population (referring to the registration rate of elderly registered residence population aged 60 and above as the denominator, and tuberculosis patients aged 60 and above as the numerator) was 263.51/100 000. The highest rate was 300.02/100,000 in 2017, and the lowest was 188.19/100,000 in 2020 (χ²=70,227.603, P<0.001). In terms of composition, the average annual proportion of tuberculosis patients in the 60-70 years old group was 59.60%, which decreased year by year (χ²_trend=40.448，P<0.001 ). The average annual proportion of males was 73.35%, which was significantly higher than that of females (26.65%). The average annual proportion of farmers was 62.03%. From the perspective of case management, the annual average proportion of major epidemic online reports was 85.17%. The classification of cases was mainly based on clinical diagnosis, accounting for 48.33% annually and showing a decreasing trend year by year (χ²_trend=740.911, P<0.001). The proportion of confirmed cases was 25.08%, which showed an increasing trend (χ²_trend=380.557, P<0.001). From 2016 to 2019, the delay rate of diagnosis and treatment of elder tuberculosis patients was 49.42% (67 876/135 967), and the delay rate decreased year by year (χ²_trend=323.764, P<0.001). Conclusion The elderly population with pulmonary tuberculosis in Hubei Province shows a downward trend. It is necessary to focus on the efforts of designated hospitals to proactively identify cases, increase the proportion of confirmed cases, maintain a high tracking in place, reduce medical delays, and ensure the effectiveness of tuberculosis prevention and treatment for the elderly.

Glioblastoma is the most common primary malignant tumor of brain in adults.Although great efforts have been made to improve prognosis in recent years,the median survival is still less than 20 months,and less than 5％of patients survive longer than 20 months.The standard treatment is maximum surgical excision combined with radiotherapy and temozolomide chemotherapy.Single cell RNA sequencing(scRNA-seq)technology accurately analyzes each unique cell,enabling us to better understand the heterogeneity of tumors,the evolution process of tumor cells,the special functions of various types of cells in the immune microenvironment,and the interactions between cells,thus providing new ideas for personalized clinical therapy.This review focuses on the application of scRNA-seq in the study of glioblastoma heterogeneity,tumor immune microenvironment,cell communication and treatment.

Objective:To analyze factors associated with timely vaccination of pertussis-containing vaccines in children born in Shanghai from 2019 to 2023.Methods:Children born in Shanghai between 2019 and 2023 were selected using a stratified random sampling method, and their vaccination data were obtained from the Shanghai Vaccine Management and Vaccination Service Information System. The vaccination rates, timely vaccination rates, and the proportions of diphtheria-tetanus-acellular pertussis-haemophilus influenzae type b combination vaccine (DTaP-Hib) and diphtheria-tetanus-acellular pertussis-inactivated poliovirus-haemophilus influenzae type b combination vaccine (DTaP-IPV-Hib) for the substitution of diphtheria- tetanus-acellular pertussis vaccine (DTaP) were calculated. Also, the factors associated with timely vaccination rate was analyzed with multivariate logistic regression analysis.Results:The average vaccination coverage rate of pertussis-containing vaccines in children born in Shanghai from 2019 to 2023 ranged from 94.71% to 99.53%. There were significant differences in the vaccination coverage of the 1 st-4 th doses of pertussis-containing vaccines among children born in different years (all P<0.05), but no gender and area specific significant differences were observed (all P>0.05). Non-national immunization program (non-NIP) vaccines were used to substitute DTaP vaccines in some children, with the proportion of DTaP-IPV-Hib vaccine accounting for 50.11%-52.69% and the proportion of DTaP-Hib vaccine accounting for 27.22%-28.43%. The proportions of DTaP-Hib and DTaP-IPV-Hib for the substitution of DTaP had increasing trends over the years. The overall timely vaccination rate of pertussis-containing vaccine vaccination was 84.09%. Analysis on the factors affecting the timely vaccination rate showed that the rate gradually decreased with the increase of the doses. Children who received the self-paid quadrivalent or pentavalent vaccines were less likely to have vaccination delays. Birth year had a significant impact on the timely vaccination rate, while the area had less impact. Additionally, the timely vaccination rate was also influenced by the degree of non-pharmaceutical intervention measures. Conclusions:The substitution of pertussis- containing vaccines with non-NIP vaccines was common in Shanghai. The coverage and timeliness of pertussis-containing vaccine vaccination were relatively high. The timely vaccination rate was significantly associated with gender, dose, vaccine type, and the degree of non-pharmaceutical interventions. There was a certain proportions of delayed and missed vaccinations, and it is necessary to pay attention to children who are not vaccinated timely and conduct high-quality catch-up vaccination to ensure timely and complete vaccination of pertussis-containing vaccines.

Objective:To screen for preoperative frailty risk factors in elderly patients with spinal degenerative diseases and construct a risk prediction model.Methods:From September 2021 to August 2022, convenience sampling was used to select 324 elderly patients who underwent spinal surgery in the Department of Neurosurgery at Xuanwu Hospital, Capital Medical University as research subjects. The patients were surveyed using the General Information Questionnaire, Barthel Index, Nutritional Risk Screening 2002, Mini-mental State Examination, Geriatric Depression Scale-15, Generalized Anxiety Disorde-7, Athens Insomnia Scale, Charlson Comorbidity Index (CCI), and Modified Frailty Index. Binary Logistic regression analysis was used to explore the influencing factors of preoperative frailty in elderly patients with spinal degenerative diseases and establish a risk prediction model. Receiver Operating Characteristic (ROC) curve was used to assess the discriminative power of the model, and Hosmer-Lemeshow test was used to evaluate the goodness of fit of the model.Results:A total of 324 questionnaires were distributed, and 308 valid questionnaires were collected, with a valid response rate of 95.06% (308/324). Among 308 elderly patients with degenerative spinal diseases, 56 patients experienced preoperative frailty. Binary Logistic regression analysis showed that falls within one year, CCI, serum albumin, activities of daily living, and self-rated health status were the influencing factors for preoperative frailty in elderly patients with spinal degenerative diseases ( P<0.05). The area under the ROC curve of the prediction model was 0.851, with a sensitivity of 0.786 and a specificity of 0.778. Hosmer Lemeshow test indicated that the predictive model had a good fit (χ 2=3.764, P=0.709) . Conclusions:Falls within one year, CCI, serum albumin, activities of daily living, and self-rated health status are influencing factors for preoperative frailty in elderly patients with spinal degenerative diseases. The risk prediction model constructed can identify preoperative frailty early and has good predictive performance, which is worthy of clinical promotion.

ObjectiveTo establish an ischemia-reperfusion model in cynomolgus macaques and to analyse the effects of edaravone intervention. MethodsA total of fifteen adult male cynomolgus macaques were randomly divided into three groups: sham operation (Sham group, n=3), ischemia-reperfusion model (Model group, n=6) and edaravone treatment (Edaravone group, n=6). Ischemic-reperfusion model of cynomolgus macaques was established by clamping the M1 branch of the left cerebral artery for 1 h. After 2 h of reperfusion, the animals in Edaravone group were injected with 0.5 mg/kg edaravone intravenously for intervention treatment, while the animals in Sham and Model groups were injected with an equal volume of normal saline intravenously, twice a day, from the 2nd to 7th day. The behavioral video recordings, clinical observations and neurological deficit scores of cynomolgus macaques were obtained, and brain edema volume and cerebral ischemia volume were statistically analyzed. ResultsCompared with the Sham group, the animals in Model group showed typical symptoms of ischemic stroke, with a significant increase in the neurological deficit score， the volumes of edema and infarct of brain tissue (all P＜0.01). Compared with Model group, the neurological deficit score, the volumes of edema and infarct of brain tissue were significantly reduced in Edaravone group (all P＜0.05). ConclusionAn animal model of ischemia-reperfusion in cynomolgus macaques was successfully established, and edaravone was confirmed to alleviate the damage caused by ischemia-reperfusion.

Objective:To investigate the impact of connexin 43(CX43) on the connection of S24 glioblastoma multiforme (S24-GBM) cellular network and to explore its role on radio-resistance.Methods:Specific lentiviral vectors were used to knockout CX43 in S24-GBM stem cells (S24-GBMSCs). Alternatively, carbenoxolone (CBX) was used to block transmission of CX43. Subsequently, the animal subjects grafted with S24-GBMSCs were monitored under a multiphoton laser scanning microscope (MPLSM). Dynamic changes of tumor microtubes (TMs) and transmission of Ca 2+ and SR101 in the cellular network were recorded. To study the radiosenstivity of S24-GBM before and after CX43 inhibition, MRI scanning of the brains was taken before and after radiation to assess the tumor sizes. Survival time of each subject was also recorded. Results:In comparison with control group, knockout of CX43 in S24-GBMSCs led to shorter TMs, less TM connected cells, lower Ca 2+ synchronicity and SR101 fluorescence, as well as decreased tumor sizes and prolonged survival time (all P<0.01), which were independent from radiation. However, CBX only demonstrated inhibition on the growth of tumors and the diffussion of Ca 2+ and SR101, without affecting TMs formation. These above-mentioned alterations could be enhanced by the combination of gap43 knockout in S24-GBMSCs with blockage of CX43 by CBX (all P<0.05). Conclusion:CX43 plays a critical role in the radioresistance of S24-GBM by influencing the formation of S24-GBM cellular network and the transmission of important signaling molecules including Ca 2+ and SR101.

Objective To analyze the treatment outcomes of multidrug-resistant pulmonary tuberculosis (MDR-TB) cases in Hubei Province. Methods From October 2006 to June 2017, a retrospective cohort analysis of treatment outcomes for 1 447 patients with MDR-TB who were included in treatment was performed. Excel worksheet was created to establish database by monthly and quarterly reports. The statistical analysis of data was conducted using SPSS 21.0 software. Results Among 1 447 MDR-TB patients, 1 076 were males and 371 were females, with an average age of 44.44±14.28 years. 798 patients were cured, 63 patients completed the course of treatment, and the overall treatment success rate was 59.50% (861/1 447). The treatment success rate was68.02% (268/394) in newly diagnosed cases, and 56.32% (593/1 053) in relapse cases. There was a significance difference between the two groups (χ²=16.30，P<0.05). The treatment success rate [78.41% (672/857)] in patients with negative sputum culture at the end of 6th month was higher than the rate [38.71% (12/31)] of negative sputum culture at the end of 12nd month, with a statistical significance difference (χ²=26.65，P<0.05). The treatment success rate [12.07% (14/116)] in patients with continued positive sputum culture at the end of 6th month was higher than the rate [4.44% (2/45)] of negative sputum culture at the end of 12th month, with a significance difference (χ²=1.34，P=0.25). Conclusion It is extremely important to screen drug-resistant individuals for smear-positive patients, and to detect and treat drug-resistant patients timely. The negative conversion of sputum bacteria at the end of 6th month had important predictive significance for the treatment outcomes of MDR-TB patients. The patients with continued positive sputum at the end of 6th month should be closely monitored to adjust treatment according to the progress of the patient's condition and to explore a way to shorten the treatment course.
