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.

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 keywords of "standardized training of general practitioner residents" or "general practice standardized training" or "general practitioner standardized training" or "general practice training" and "community-based teaching " or "community training" "community base" or "community teaching" were used for search, and affiliations of authors should contain"community health service center". 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 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 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.

Objective To investigate the associations of reproductive health indicators with lung function and chronic obstructive pulmonary disease(COPD)among women aged 40 years and above.Methods From Jul to Sep,2021,female subjects aged 40 years and above were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for COPD screening.A questionnaire was used to obtain information on demographic characteristics and reproductive health indicators.Linear regression was used to analyze the effects of reproductive health indicators on forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1).Logistic regression was also used to analyze the effects of reproductive health factors on FVC as a percentage of the predicted value(FVC%Pred)and FEV1%Pred as well as on COPD.Results A total of 1876 women aged 40 years and above were enrolled with mean age of(62.1±8.2)years old,among them,78.1%were menopausal,and 40.9%had been pregnant≥3 times.Multivariate analysis showed that FVC and FEV1 decreased in postmenopausal women,but menopause was not associated with a decrease in their percentage of predicted values.Pregnancies≥3 times was a risk factor for COPD(for 3 times,OR=4.92,95%CI:1.48-19.95,P<0.05;for≥4 times,OR=9.06,95%CI:2.32-41.57,P<0.01),while pregnancies of 2 times did not increase the risk of COPD.Conclusion In women aged 40 years and above,menopause is associated with poorer FVC and FEV1,and excessive pregnancy(≥3 times)is a risk factor for COPD.

Non-alcoholic fatty liver disease(NAFLD)is a series of diseases characterized by hepatic steatosis and is also a metabolism-associated disease and an important factor for liver fibrosis,liver cirrhosis,and hepatocellular carcinoma.Endoplasmic reticulum is a core organelle for the regulation of lipid metabolism,and unfolded protein response is an important process of endoplasmic reticulum stress(ERS).Based on the important stress role of endoplasmic reticulum in metabolism-associated diseases,this article explores the influencing mechanism between ERS and NAFLD and reviews the research advances in lipid metabolism,inflammatory response,hepatocyte death,fibrosis,and ERS-targeted therapies in the pathological development of NAFLD.

The NiFe2O4-graphene oxide nanocomposite modified with polyethylenimine(GO@PEI-NiFe2O4)was prepared to purify and enrich phosphopeptides from biosamples.The Ni2+and Fe3+ions on its surface could coordinate with phosphate groups and then selectively adsorb phosphopeptides.PEI was conducive to the above combination due to its high hydrophilicity.The material showed good magnetic response properties and could be rapidly separated from samples with the aid of magnet.With tryptic digest of β-casein as sample,the enrichment property of the material to phosphopeptides was studied,which was compared with the results of GO@NiFe2O4,revealing the adsorption mechanism of GO@PEI-NiFe2O4.The static and dynamic binding properties of GO@PEI-NiFe2O4 were investigated using pTyr as a representative phosphopeptide,and the adsorption capacity was 36.2 μg/mg.The results showed that the material could remove the interference of nonphosphopeptides and effectively enrich phosphopeptides in complex matrix.After enrichment by GO@PEI-NiFe2O4,1535 phosphopeptides were identified from the tryptic digest of rat liver by mass spectrum and the enrichment effect of GO@PEI-NiFe2O4 greatly outperformed commercial Fe3+-IMAC kits.This work provided an efficient material for the enrichment of phosphopeptides,showing potential applications in phosphoproteomics research.

Objectives:To investigate the value of metagenomic next-generation sequencing (mNGS) in the diagnosis of Pneumocystis jirovecii pneumonia (PJP) in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:The data of 98 patients with suspected pulmonary infection after allo-HSCT who underwent pathogen detection from bronchoalveolar lavage fluid between June 2016 and August 2023 at Nanfang Hospital were analyzed. The diagnostic performance of mNGS, conventional methods, and real-time quantitative polymerase chain reaction (qPCR) for PJP were compared.Results:A total of 12 patients were diagnosed with PJP, including 11 with a proven diagnosis and 1 with a probable diagnosis. Among the patients with a proven diagnosis, 1 was positive by both conventional methods and qPCR, and 10 were positive by qPCR only. Pneumocystis jirovecii was detected by mNGS in all 12 patients. The diagnostic sensitivity of mNGS for PJP was 100%, which was greater than that of conventional methods (8.3%, P=0.001) and similar to that of qPCR (91.6%, P=1.000) . A total of 75% of the patients developed mixed pulmonary infections, and cytomegalovirus and Epstein-Barr virus were the most common pathogens. Mixed infection was detected in eight patients by mNGS and in five patients by qPCR, but not by conventional methods ( P=0.008) . Conclusions:mNGS had good sensitivity for diagnosing PJP after allo-HSCT and was advantageous for detecting mixed infectious pathogens; therefore, mNGS might be an effective supplement to regular detection methods and qPCR.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To explore the impact of rehabilitation exercise intervention mode based on cardiac function classification on clinical effect and quality of life(QOL)in patients with chronic heart failure(CHF).Methods:A total of 160 CHF patients who visited our hospital from Dec 2021 to Jan 2023 were selected,and 154 cases were fi-nally enrolled.According to the random number table method,patients were divided into study group and control group with 77 cases in each group.Control group received routine nursing program,while the study group received rehabilitation exercise intervention based on cardiac function classification on the basis of control group,both groups were intervened for three months.Clinical total effective rate,and cardiopulmonary function,serum oxidative stress indicators and MLHFQ score before and after intervention were compared between two groups.Results:Total effective rates of study subgroups of class Ⅱ and Ⅲ were significantly higher than those of control group(class Ⅱ:100.00％vs.83.78％;class Ⅲ:97.37％vs.80.00％)(P＜0.05 both).Compared with control subgroup of classⅢ after intervention,there were significant rise in peak VO2[(16.98±2.03)ml·min-1·kg-1 vs.(18.61±2.41)ml·min-1·kg-1],LVEF[(41.73±4.53)％vs.(48.03±5.22)％]and 6MWD[(351.34±61.00)m vs.(391.53±64.42)m](P＜0.01 all);and significant reductions in LVEDd[(57.55±3.91)mm vs.(53.18±3.07)mm],LVESd[(35.90±2.91)mm vs.(30.50±2.67)mm],levels of LPO[(6.00±0.99)mg/L vs.(3.95±0.61)mg/L],MPO[(3.83±0.58)mg/L vs.(2.03±0.28)mg/L],and MLHFQ total score[(57.05±4.57)points vs.(45.29±3.94)points]in study subgroup of class Ⅲ(P=0.001 all).Compared with control subgroup of class Ⅱ after intervention,there were significant rise in peak VO2,LVEF and 6MWD,and significant reductions in LVEDd,LVESd,levels of LPO,MPO and MLHFQ score in study subgroup of class Ⅱ,P＜0.05 or＜0.01.There was no significant difference in the incidence rate of adverse events during follow-up between two groups(3.90％vs.6.49％,P=0.717).Conclusion:Rehabilitation exercise intervention based on cardiac function classifi-cation can significantly improve cardiopulmonary function,inhibit oxidative stress response in vivo and improve quality of life in CHF patients,which is worthy of promotion and application in clinical practice.
