Objective:To evaluate the value of applying targeted next-generation sequencing on bronchoalveolar lavage fluid specimens in screening pulmonary tuberculosis in older adults with lung infectious diseases.Methods:In this cross-sectional study, the clinical data of 370 patients with infectious lung diseases who received treatment at Shanghai Deji Hospital between January 2021 and July 2023 were analyzed. Bronchoscopy was performed to obtain 370 bronchoalveolar lavage fluid specimens, and targeted next-generation sequencing confirmed the diagnosis of pulmonary tuberculosis in 28 patients. The clinical data of these 28 patients were retrieved from the electronic medical record system. Patient age, clinical characteristics, comorbidities, methods of diagnosis, imaging findings, and results of pathogen testing were analyzed.Results:The patients' ages ranged from 70 to 93 years. Among the 28 patients included, 16 patients were in the medium-age (> 70-80 years) group and 12 patients were in the advanced age (> 80 years) group. Clinical findings revealed that 9 patients (32.1%) exhibited fatigue, 8 patients (29.6%) presented with cough and sputum, 4 patients (14.3%) experienced chest tightness, 4 patients (14.3%) had loss of appetite, and 3 patients (10.7%) showed a reduction in body mass. Furthermore, 12 patients had diabetes mellitus, 10 patients had infectious lung diseases, 4 patients had lung cancer, and 2 patients had liver and kidney insufficiency. Tuberculosis was passively confirmed by the targeted next-generation sequencing test. Imaging findings indicated the presence of two or more lesions in the lungs of 24 patients (85.7%), while 4 patients (14.3%) showed only one lesion in the lung. There was a significant difference between the number of patients with two or more lesions compared with those with only one lung lesion ( χ2 = 25.79, P < 0.001). The positive rate of the conventional pathogen test among the 28 patients was 14.3%, which was significantly different from that obtained by targeted next-generation sequencing on bronchoalveolar lavage fluid specimens ( χ2 = 68.55, P < 0.001). Conclusion:The onset of pulmonary tuberculosis in older adults is subtle, and its complications can result in clinical symptoms and imaging findings that lack specificity. Conventional methods of positive etiology detection often yield low accuracy rates. However, the application of targeted next-generation sequencing on bronchial bronchoalveolar lavage fluid specimens collected from older adult patients with respiratory infectious diseases at non-tuberculosis-designated hospitals can enhance the positive detection rate. This approach can facilitate earlier diagnosis and treatment of pulmonary tuberculosis in older adults, ultimately contributing to the prevention of its transmission.

Objective:To investigate the incidence and mortality of breast cancer in tumor registration areas of Shanxi Province in 2019.Methods:A cross-sectional study was conducted. The tumor registration data reported by 13 tumor registration areas in Shanxi Province in 2019 were collected, and the overall incidence and mortality of breast cancer were analyzed. The stratified analysis was conducted by gender and region, and the incidence, mortality, accumulation rate (0-74 years old), age-specific incidence rate, age-specific mortality rate, Chinese population standardized rate and world population standardized rate were calculated. The standard population was based on the 2000 China population census standard population composition and Segi world standard population composition.Results:In 2019, there were 871 new cases of breast cancer in the tumor registration areas of Shanxi Province, with an incidence rate of 17.83/100 000, and 202 deaths, with a mortality rate of 4.13/100 000. The age-specific incidence of breast cancer was at a low level in 0-25 years old, it increased rapidly after 30 years old, and reached a peak in people aged 60 years old. The age-specific mortality showed a slow rising trend with the increase of age, and increased rapidly in people over 75 years old. The age-specific incidence and mortality of breast cancer in female were higher than those in male. Although the general trend of change concerning urban and rural age-specific incidence was similar, the trend of change concerning urban and rural age-specific mortality had their own characteristics. In 4 urban tumor registration areas, the highest male and female Chinese population standardized incidence rates were found in Yuci District of Jinzhong City (0.62/100 000) and Yangquan City (41.86/100 000). Male Chinese population standardized mortality rate was 0/100 000, and the highest female Chinese population standardized mortality rate was found in Yangquan City (12.62/100 000). In 9 rural tumor registration areas, the highest male and female Chinese population standardized incidence rates were found in Jishan County (2.59/100 000) and Pingding County (36.42/100 000). The highest Chinese population standardized mortality rates were found in Yuanqu County (0.89/100 000) and Jishan County (4.82/100 000).Conclusions:Women, urban area people and middle-aged and elderly people are the foci of breast cancer prevention and control in Shanxi Province.

Objective:To explore the effect of silent information regulator 1 (SIRT1) activator SRT1720 on inflammatory response in chronic periodontal disease mice and whether its mechanism is related to the toll like receptor 4 (TLR4)/nuclear factor κB (NF-κB) signaling pathway.Methods:Forty 8-week-old male C57BL/6 mice were selected and divided into a blank control group ( n=8) and an experimental group ( n=32). The experimental group mice were ligated with periodontal pockets and fed with high sugar drinking water. The experimental group was randomly divided into a model group ( n=8) and an SRT1720 group ( n=24). The blank control group and the model group were given physiological saline orally every day. The SRT1720 group was further divided into a low dose group [20 mg/(kg·d), n=8], a medium dose group [50 mg/(kg·d), n=8], and a high dose group [100 mg/(kg·d), n=8] based on the different doses of SRT1720. Four weeks later, the expression levels of interleukin-6 (IL-6), interleukin-1β (IL-1β) and monocyte chemoattractant protein-1 (MCP-1) in gingival crevicular fluid of mice in each group were detected by enzyme linked immunosorbent assay (ELISA); The real-time quantitative polymerase chain reaction (RT-qPCR) method was used to detect the mRNA expression levels of IL-6, IL-1β, MCP-1, SIRT1, TLR4, NF-kB p65 in the gingival tissue of mice in each group; Western blot was used to determine the expression levels of SIRT1, TLR4, and NF-κB p65 proteins in mouse gingival tissue. Results:Compared with the blank control group, the expression levels of IL-6, IL-1β, and MCP-1 inflammatory factors in the gingival crevicular fluid of experimental group mice increased, while the expression levels of IL-6, IL-1β, MCP-1, TLR4, NF-κB p65 mRNA in gingival tissue increased. The expression levels of TLR4, NF-κB p65 protein in gingival tissue increased, while the expression levels of SIRT1 mRNA and protein in gingival tissue decreased, with statistical significance (all P<0.05). Compared with the model group, the expression levels of IL-6, IL-1β, and MCP-1 inflammatory factors in the gingival crevicular fluid, IL-6, IL-1β, MCP-1, TLR4, NF-κB p65 mRNA expression levels in gingival tissue, and TLR4, NF-κB p65 protein expression levels in the gingival tissue of SRT1720 group mice showed a dose-dependent decrease. The expression levels of SIRT1 mRNA and protein in gingival tissue showed a dose-dependent increase, and the differences were statistically significant (all P<0.05). Conclusions:SIRT1 activator SRT1720 can improve the inflammatory response of chronic periodontal disease mice, which may be related to the inhibition of TLR4/NF-kB signaling pathway.

Objective:To investigate the incidence and mortality of lung cancer in the cancer registration areas of Shanxi Province in 2017.Methods:The cancer registration data reported by 12 tumor registration areas of Shanxi in 2017 were sorted out and stratified by urban and rural areas and gender. The number of incidence and death ,the crude incidence and mortality, the cumulative rate (0-74 years), age-specific incidence and mortality, Chinese population standardized rate and world population standardized rate were calculated. The incidence and mortality were standardized by the 2000 China census standard population composition and Segi's world standard population composition.Results:In 2017, there were 2 275 new cases and 1 736 deaths of lung cancer in the tumor registration area of Shanxi Province. The crude incidence rate of lung cancer was 46.72/100 000 (male 63.99/100 000, female 28.80/100 000, urban area 58.05/100 000, rural area 39.09/100 000), Chinese population standardized rate was 31.67/100 000, the world population standardized rate was 32.10/100 000, and the cumulative rate (0-74 years) was 3.87/100 000. The crude mortality rate was 35.65/100,000 (male 49.84/100,000, female 20.93/100,000, urban area 44.53/100,000, rural area 29.67/100 000), Chinese population standardized rate was 23.82/100 000, the world population standardized rate was 24.14/100 000, and the cumulative rate (0-74 years) was 2.69/100,000. Overall, the age-specific incidence and mortality of lung cancer in 2017 were at a low level in 0-44 years age group, and increased rapidly after 45 years age group, and reached a peak in 85 years age group. The incidence and mortality of lung cancer in males were higher than that in females. Although there were some differences in the incidence and mortality of patients with different ago range in urban and rural areas, the overall trend was similar.Conclusions:Lung cancer is the most common malignant tumor threatening the health of residents in Shanxi Province. Male, urban areas and middle-aged and elderly population are the focus of cancer prevention and control in Shanxi Province. Lung cancer prevention and control should be targeted carried out according to the differences between urban and rural areas and gender.

Objective:To realize the understanding level of cancer awareness of residents in Shanxi Province, and to provide a scientific basis for cancer prevention and treatment.Methods:In April 2020, 1 897 local residents in Shanxi Province were recruited to fill in the core knowledge questionnaire of cancer prevention and treatment. The basic demographic information and the core knowledge of cancer prevention and control were collected, and the influencing factors for the understanding of the core knowledge of cancer prevention and treatment were analyzed by using multivariate logistic regression model.Results:In the survey on the awareness rate of core knowledge of cancer prevention and control among residents in Shanxi Province, 37 940 items were answered, among which 29 396 items were known, and the awareness rate of the population was 77.48% (29 396/37 940). The single-factor results showed that there were statistically significant differences in awareness rates of core knowledge of cancer prevention and treatment among the population with different gender, household registration, ethnic groups, education degree, occupation and different frequency of the health examination were statistically significant (all P < 0.05); there were no statistically significant differences in awareness rates of core knowledge among the population with different age, and smokers or non-smokers (all P >0.05).Multivariate logistic regression analysis showed that education degree of junior middle school or above ( OR = 3.412-16.767, 95% CI 1.755-32.476) and receiving physical examination once a year ( OR = 2.291, 95% CI 1.154-4.549) were the favorable factors for knowing the core knowledge of cancer prevention and treatment. Household location in rural area ( OR = 0.522, 95% CI 0.378-0.722) and non-Han nationality ( OR = 0.369, 95% CI 0.151-0.904) were the unfavorable factors for knowing the core knowledge of cancer prevention and treatment. Conclusions:The awareness of core knowledge of cancer prevention and treatment among residents in Shanxi Province is good, so it is necessary to continue to strengthen the publicity of cancer prevention and control and improve the awareness of cancer prevention and control in the future.

Objective This study aims to investigate the effect of rehabilitation skills training on suicide and relapse prevention of patients with depression.Methods Eighty patients were randomly divided into two groups.One group accepted depression rehabilitation skills training and the other group accepted general health education for 4 weeks.Both groups were followed up by 12 months,and the number of relapse and suicide and the score of Health-related quality of life made by Word Health Organization (WHOQOL-BREF) were recorded.Results The rate of relapse (10.0％ vs.42.5％) and hospitalization (5.0％ vs.20.0％) were lower in skills training group than in control group (P＜0.05).Rate of seeking help of suicide was higher in skills training group than in control group (25.5％ vs.7.5％) (P＜0.05).The suicide mortality was insignificantly different between two groups (0.0％ vs.2.5％) (P＞0.05).The scores of WHOQOL-BREF were significantly higher in skills training group than in control group in follow-up (P＜0.05).Conclusions Rehabilitation skills training program can not only reduce the rate of relapse and suicide but also improve the quality of life of patients with depression.

Objective To evaluate the diagnostic accuracy and efficacy on cervical precancerous lesions and cervical cancer by HPV 16/18 E6 protein detection. Methods A total of 439 females with sexual activities were selected from Department of Gynaecology in Shanxi Cancer Hospital from May 2014 to January 2015, including 299 cases of cervical intraepithelial neoplasia (CIN)Ⅱ, CINⅢ or cervical cancer (the case group), and the other 140 cases (the control group). All the patients accepted the thinprep cytology test (TCT), HPV DNA and HPV 16/18 E6 oncoprotein tests and colposcope examination. Results The positive rates of the TCT, HPV DNA, HPV 16/18 E6 oncoprotein in the case group were 97.0 % (290/299), 94.3 % (282/299) and 66.9 % (200/299), respectively, and those in the control group were 44.3 % (62/140), 21.4 % (30/140) and 2.9%(4/140), respectively, and there were significant differences between both groups (all P<0.05). The sensitivity and specificity of the HPV 16/18 E6 oncoprotein test in detecting CINⅡ and above were 66.9 %and 97.1 %, respectively, and both of HPV DNA test were 94.3 % and 78.6 %, respectively; The consistent rate between HPV 16/18 E6 and HPV DNA was 71.9 % (κ= 0.21). In the case group, when TCT was associated with HPV DNA test, the sensitivity, specificity and accuracy were 98.9%, 82.8%and 81.7%, respectively, and when TCT was combined with HPV 16/18 E6 oncoprotein test, those were up to 97.9 %, 97.1 % and 95.0 %. Conclusion HPV 16/18 E6 oncoprotein test can improve the specificity of cervical cancer screening, so it may be used as a primary screening method in the less developed areas where HPV DNA test is difficult to be carried out, or as a shunt method for HPV DNA positive patients, which will allocate the limited health resources rationally.
