Objective: To analyze the epidemiological characteristics and spatial-temporal clustering characteristics of pulmonary tuberculosis in Huangpu District, Shanghai Municipality from 2009 to 2023, so as to provide the evidence for formulating targeted pulmonary tuberculosis prevention and control strategies. Methods: Data of registered pulmonary tuberculosis cases in Huangpu District from 2009 to 2023, including gender, age, occupation, and pathogenetic test results, were collected from the Tuberculosis Management Information System of the China Disease Prevention and Control Information System. The registered incidence was calculated, and the trend was analyzed using the annual percent change (APC) and average annual percent change (AAPC). Spatial distribution pattern was analyzed using kernel density estimation and the average nearest neighbor methods. The temporal-spatial clustering characteristics of pulmonary tuberculosis were identified using the spatio-temporal scan analysis. Results: A total of 2 726 pulmonary tuberculosis cases were registered in Huangpu District from 2009 to 2023. The registered incidence decreased from 31.20/100 000 in 2009 to 15.06/100 000 in 2023 (AAPC=-6.156%, P<0.05). A sharp declining trend was particularly observed from 2017 to 2023 (APC=-11.355%, P<0.05). Among them, 1 239 were pathogen-positive, and the pathogen positivity rate increased from 40.80% in 2009 to 71.05% in 2023 (P<0.05). There were 1 906 male cases and 820 female cases, with a male-to-female ratio of 2.32∶1. There were 798 cases aged 45-<60 years and 981 retirees, accounting for 29.27% and 35.99%, respectively. Temporal-spatial clustering analysis revealed spatial clustering areas during both 2009-2016 and 2017-2023 (both P<0.05). The clustering area for 2009-2016 was located in the central-eastern part of Huangpu District, with the clustering time in 2012. The clustering area for 2017-2023 was in the southwestern part, with the clustering time in 2017. Conclusions The registered incidence of pulmonary tuberculosis in Huangpu District showed a downward trend from 2009 to 2023. The spatial clustering areas were identified in the central-eastern part in Huangpu District in 2012 and the southwestern part in 2017.

The renin-angiotensin-aldosterone system (RAAS) is crucial for regulating blood pressure and maintaining fluid balance, while clock genes are essential for sustaining biological rhythms and regulating metabolism. There exists a complex interplay between RAAS and clock genes that may significantly contribute to the development of various cardiovascular and metabolic diseases. Although current literature has identified correlations between these two systems, the specific mechanisms of their interaction remain unclear. Moreover, the interaction patterns under different physiological and pathological conditions need further investigation. This review summarizes the synergistic roles of the RAAS and clock genes in cardiovascular diseases, explores their molecular mechanisms and pathophysiological connections, discusses the application of chronotherapy, and highlights potential future research directions, aiming to provide novel insights for the prevention and treatment of related diseases.

This study explores whether the current external quality assessment (EQA) level and acceptable bias for basic semen analysis in China are clinically useful. We collected data of semen EQA from Andrology laboratories in the Hunan Province (China) in 2022 and searched for data in the published literature from January 2000 to December 2023 in China. On the basis of these data, we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics. We compared these findings with quality specifications based on biological variation from optimal, desirable, and minimum levels of bias to seek a unified and more suitable semen EQA bias evaluation standard for China's national conditions. Different sources of semen quality control material exhibited considerable variation in acceptable biases among laboratories, ranging from 8.2% to 56.9%. A total of 50.0% of the laboratories met the minimum quality specifications for progressive motility (PR), whereas 100.0% and 75.0% of laboratories met only the minimum quality specifications for sperm concentration and total motility (nonprogressive [NP] + PR), respectively. The Z value for sperm concentration and PR+NP was equivalent to the desirable performance specification, whereas the Z value for PR was equivalent only to the minimum performance specification. This study highlights the feasibility of operating external quality assessment schemes for basic semen analysis using quality specifications based on biological variation. These specifications should be unified among external quality control (EQC) centers based on biological variation.

Neuropathic pain, a debilitating condition caused by dysfunction of the somatosensory nervous system, remains difficult to treat due to limited understanding of its molecular mechanisms. Bioinformatics analysis identified cerebellin 2 (CBLN2) as highly enriched in human and murine proprioceptive and nociceptive neurons. We found that CBLN2 expression is persistently upregulated in dorsal root ganglia (DRG) following spinal nerve ligation (SNL) in mice. In addition, transcription factor SOX11 binds to 12 cis-regulatory elements within the Cbln2 promoter to enhance its transcription. SNL also induced SOX11 upregulation, with SOX11 and CBLN2 co-localized in nociceptive neurons. The siRNA-mediated knockdown of Sox11 or Cbln2 attenuated SNL-induced mechanical allodynia and thermal hyperalgesia. High-throughput sequencing of DRG following intrathecal injection of CBLN2 revealed widespread gene expression changes, including upregulation of numerous NF-κB downstream targets. Consistently, CBLN2 activated NF-κB signaling, and inhibition with pyrrolidine dithiocarbamate reduced CBLN2-induced pain hypersensitivity, proinflammatory cytokines and chemokines production, and neuronal hyperexcitability. Together, these findings identified the SOX11/CBLN2/NF-κB axis as a critical mediator of neuropathic pain and a promising target for therapeutic intervention.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Objective:To investigate the efficacy and safety of daratumumab (Dara) - combination regimens for newly diagnosed multiple myeloma (NDMM).Methods:A retrospective case series study was conducted. The clinical data of 34 patients with NDMM receiving treatment regimen including Dara from Qilu Hospital of Shandong University, Yantai Yuhuangding Hospital, Huangdao Branch of Affiliated Hospital of Qingdao University and Taian City Central Hospital between April 2020 and March 2022 were retrospectively collected. The efficacy, survival and adverse reactions of patients were analyzed. Cox proportional risk model was used to analyze the factors affecting overall survival (OS) and minimal residual disease (MRD) turning negative.Results:Among 34 patients with NDMM, there were 19 males and 15 females, with 21 cases aged < 65 years and 13 cases aged ≥65 years. The median follow-up duration [ M ( Q1, Q3)] was 22 months (19 months, 26 months), the median of Dara treatment cycles was 7 (5, 11), and the overall response rate (ORR) reached 97.1% (33/34). There were statistically significant differences in the optimal efficacy of patients stratified by receiving hematopoietic stem cell transplantation or not and receiving different treatment cycles (all P ≤ 0.05), while there were no statistically significant differences in patients stratified by other clinical features (all P > 0.05). The 1-year progression-free survival rate was 79.4% and the 1-year OS rate was 94.1%. Multivariate Cox regression analysis showed that the cycle number of treatment regimens containing Dara was an independent influencing factor of MRD turning negative (6 cycles vs. 2 cycles, HR = 0.267, 95% CI: 0.076-0.935, P = 0.039); age ≥ 65 years was an independent risk factor for OS ( HR = 35.313, 95% CI: 1.709-729.669, P = 0.021). The incidence of hematological adverse reactions grade 3 or above was 20.6% (7/34), and the non-hematological adverse reactions primarily included infection [44.1% (15/34)] and edema of extremity and trunk [41.2% (14/34)]. Conclusions:The Dara-based regimens for NDMM exhibit a high ORR. The remission depth accelerated with the increasing number of treatment cycle, and the adverse reactions are mild.

Objective:To investigate the status quo of educational and teaching research in community bases for general practice standardized residency training in China.Methods:The studies related to education research in community bases for general practice standardized residency training were searched from Chinese Journal Full Text Database (CNKI), Wanfang Database and China Science and Technology Journal Database (VIP) from inception to November 30, 2023.

The literature was read and summarized using Endnote and Excel software.Results:A total of 171 articles were retrieved that met the criteria, and 130 articles were finally selected for analysis according to the quality review criteria of the literature. The authors of articles were distributed in 78 institutions of 17 provinces or regions, with 9 provinces or regions having a total of 123 articles (94.6%) with 2 published articles or more, of which the highest number was found in Beijing and Shanghai. Seventeen institutions published 2 or more articles with a total of 69 articles (53.1%), including 67 articles (51.5%) were co-authored by 2 units. The ranking top ten institutions in terms of the number of articles published were 5 community health service centers in Beijing, 4 in Shanghai (co-authored with Shanghai Zhongshan Hospital). There were 46 articles (35.4%) published in core journals and 55 articles (42.3%) with fund-supported projects. The studies presented teaching methods, teaching and training contents, teaching evaluation and effects, teacher training, teaching base construction and information technology application.Conclusion:The educational and teaching research in community bases for general practice standardized training in China has gradually received attention, the researches were mainly carried out by community medical institutions, but the overall quality of research needs to be further improved.

OBJECTIVE To develop a questionnaire of the Knowledge-Attitude-Practice （KAP） for patients receiving oral anticoagulant therapy. METHODS Under the guidance of the theory of KAP， literature analysis and interview method were used to design the initial KAP questionnaire for patients treated with oral anticoagulants. Delphi method was adopted to consult the initial questionnaire and modify the questionnaire based on expert suggestions to form the final questionnaire. RESULTS Two rounds of consultation were conducted with 18 experts， and 18 questionnaires were sent out and recovered in each round， so the positive coefficient of experts was 100%. The expert authority coefficient was 0.94. The average importance scores for all dimensions， factors， and items of the questionnaire in both rounds were ≥4 points. The coefficient of variation was ≤0.25. The Kendall’s concordance coefficient for the overall questionnaire and the three dimensions of knowledge， attitude， and practice ranged from 0.09 to 0.34 （all P＜0.05）. Following the first round of expert consultation， four items were modified， two items were deleted， and five items were added； after the second round of expert consultation， ten items were modified. The final version of the questionnaire included three dimensions （knowledge， attitudes， and practice）， 17 questionnaire factors， and 40 items. CONCLUSIONS The questionnaire has high reliability and scientific validity with relatively concentrated expert opinions. It is suitable for assessing the knowledge， attitudes， and practice status of patients receiving oral anticoagulant therapy.
