Objective: To analyze the unregistered treatment situation and its influencing factors among pulmonary tuberculosis patients in Quzhou City, Zhejiang Province from 2017 to 2023, so as to provide a basis for promoting the management of tuberculosis patients and optimizing disease prevention and control strategies. Methods: Data of pulmonary tuberculosis patients including demographic information, etiological results, and mortality status were collected through the China Disease Prevention and Control Information System Infectious Disease Reporting and Surveillance System and the Tuberculosis Management Information System. Pulmonary tuberculosis patients not matched in the Tuberculosis Management Information System were defined as unregistered treatment patients, and the unregistered treatment rate was analyzed. Factors affecting unregistered treatment among pulmonary tuberculosis patients were analyzed using a multivariable logistic regression model. Results: A total of 10 779 pulmonary tuberculosis patients were reported in Quzhou City from 2017 to 2023, including 7 700 males (71.44%) and 3 079 females (28.56%). There were 5 484 cases aged <65 years, accounting for 50.88%. Among them, 630 cases were unregistered treatment, with an unregistered treatment rate of 5.84% (95%CI: 5.42%-6.38%). Multivariable logistic regression analysis showed pulmonary tuberculosis patients aged ≥65 years (OR=1.829, 95%CI: 1.512-2.212) had a higher risk of being unregistered treatment than those aged <65 years; patients with non-local household registration (OR=5.710, 95%CI: 4.724-6.901) had a higher risk than local patients; and patients engaged in housework/unemployed (OR=2.001, 95%CI: 1.421-2.818) or other occupations (OR=2.396, 95%CI: 1.789-3.137) had a higher risk than farmers. The mortality of unregistered treatment pulmonary tuberculosis patients was higher than the registered treatment patients (26.67% vs. 5.02%),with a significantly elevated mortality risk (OR=7.147, 95%CI: 5.738-8.902). Conclusions The unregistered treatment rate among pulmonary tuberculosis patients was well controlled in Quzhou City from 2017 to 2023, but the elderly, patients with non-local household registration, and those engaged in housework/unemployed had a higher risk of unregistered treatment. It is recommended to improve medical and social security policies, strengthen health education on tuberculosis prevention, enhance treatment adherence, and reduce mortality risk.

Objective:To compare the clinical outcomes and prognosis of transabdominal opening of the left diaphragm and traditional thoracoabdominal combination approach for Siewert type II adenocarcinoma of the esophagogastric junction.Methods:A retrospective cohort study was conducted. The clinical data of 59 patients with Siewert type Ⅱ adenocarcinoma of the esophagogastric junction who underwent radical total gastrectomy in Shanxi Provincial People's Hospital from January 2018 to March 2020 were retrospectively analyzed, and all patients were divided into the transabdominal opening of the left diaphragm group (30 cases) and the thoracoabdominal combination group (29 cases) according to surgical access. The general data, perioperative indexes, postoperative complications and postoperative survival of patients in the two groups were compared. Factors influencing the overall survival were analyzed by using Cox proportional hazards model.Results:The differences in terms of gender, age, tumor diameter, pT staging, and pN staging between the two groups were not statistically significant (all P > 0.05). The length of esophageal invasion was (3.5±1.1) cm and (3.7±1.1) cm, respectively in the transabdominal opening of the left diaphragm group and the thoracoabdominal combination group, and the difference was not statistically significant ( t = -0.70, P = 0.486). Compared with the thoracoabdominal combination group, the transabdominal opening of the left diaphragm group had less operative time, intraoperative bleeding, postoperative bedtime, chest tube extraction time and postoperative hospitalization days, and the differences were statistically significant (all P < 0.05); the differences in the number of lymph nodes cleared, the number of positive lymph nodes, the number of thoracic lymph node dissection, and the number of positive thoracic lymph node were not statistically significant in the two groups (all P > 0.05). The total incidence of postoperative complications in the transabdominal opening of the left diaphragm group and the thoracoabdominal combination group were 53.3% (16/30) and 72.4% (21/29), respectively, and the difference was not statistically significant ( χ2 = 2.30, P = 0.130), while the incidence of lung infection and pleural effusion in the thoracoabdominal combination group was higher than that in the transabdominal opening of the left diaphragm group (both P<0.05). The 1- and 3-year postoperative overall survival rates were 80.0%, 63.3% in the transabdominal opening of the left diaphragm group, and 79.3%, 62.1% in the thoracoabdominal combination group, respectively, and the difference in overall survival between the two groups was not statistically significant ( χ2 = 0.01, P = 0.934). Multivariate analysis showed that pT staging ( HR = 4.009, 95% CI: 1.851-8.683, P < 0.001) and pN staging ( HR = 2.338, 95% CI: 1.435-3.811, P = 0.001) were the independent influencing factors of overall survival. Conclusions:For patients with Siewert type Ⅱ adenocarcinoma of the esophagogastric junction with esophageal invasion length > 3 cm, transabdominal opening of the left diaphragm approach can reduce intraoperative bleeding and postoperative chest complications, and it has the advantages of shorter operation, hospitalization time, and less trauma, which can help to accelerate the recovery of the patients; pT and pN staging are the independent factors influencing the prognosis of patients.

Objective To explore basement membrane markers and potential drugs for treatment in idiopathic pulmona-ry fibrosis(IPF).Methods IPF-related datasets were downloaded from the Gene Expression Omnibus(GEO)database,processed to construct basement membrane gene expression matrices associated with IPF,and screened for differential basement membrane genes(DEBMs);DEBMs were enriched for function and pathways,and machine learning algorithms were used to ob-tain candidate signature genes,receiver operating characteristic(ROC)curves were used to identify signature genes and con-struct a nomogram.We performed ssGSEA analysis to explore the correlation between signature genes and immune cells and their functions and predicted the corresponding miRNAs and therapeutic drugs by signature genes.Results A total of 56 DEBMs were extracted;enrichment analysis showed that DEBMs were mainly enriched in"extracellular matrix tissue","extracellular structural tissue",etc.,and were closely related to"ECM-receptor interaction"and"local adhesion spot"pathways.The ma-chine learning has identified six candidate signature genes(TIMP3,P3H2,ITGA7,ITGA4,ADAMTS2,COL8A2),all of which meet the requirements of the signature genes by the ROC curve test,and the nomogram diagnostic value was outstanding(AUC=0.991 523);B cells and Macrophages in IPF were significantly different from the normal group.Finally,miRNAs were predicted to be dominated by miR-4305,miR-3684,progesterone,and tert-butyl hydroperoxide as therapeutic agents with strong relevance to IPF.Conclusion Signature genes and predictive miRNAs may serve as novel markers for IPF diagnosis,and pre-dictive drugs may be a potential source of drugs for treating IPF.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Rheumatoid arthritis （RA）， as an autoimmune disease， is mainly characterized by persistent synovitis. It often involves multiple joints symmetrically and can lead to joint deformity， joint function loss， and even disability in severe cases. The pathogenesis of RA is complex， and the prevention and treatment are complicated. Therefore， it is difficult to cure the disease completely. Previous studies have validated important targets and mechanisms for the prevention and treatment of RA， including the nuclear factor-κB （NF-κB） signaling pathway that controls the inflammatory process， nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway that regulates oxidative stress， inhibits inflammation， and maintains cell homeostasis， Wnt/β-catenin signaling pathway that plays a key role in cell growth， differentiation， apoptosis， and inflammatory response， anti-inflammatory， anti-oxidation， and silent information regulator 1 （SIRT1） signaling pathway that regulates synovial cells， anti-inflammatory adenylate-activated protein kinase （AMPK） signaling pathway that regulates energy metabolism， and hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF） signaling pathway related to angiogenesis in RA. At the same time， many studies have confirmed that traditional Chinese medicine prevents and treats RA by regulating the above signaling pathways and exerting their related effects， indicating the advantages of traditional Chinese medicine such as multiple regulatory pathways， long-term effects， and less adverse reactions. In this paper， by consulting many research reports， the role of the above-mentioned signaling pathways in RA was clarified， and the latest research results of traditional Chinese medicine intervention in the above-mentioned signaling pathways in the prevention and treatment of RA in recent years were summarized in detail. This paper aims to promote the in-depth study of the pathogenesis of RA and its treatment with traditional Chinese medicine， provide a scientific basis for the rational application of traditional Chinese medicine， and offer useful enlightenment for the development of new drugs and clinical practice for the treatment of RA in the future.

Objective:To investigate the expression of long non-coding RNA(lncRNA) ZFP36-AS1 in bladder cancer and the effect of ZFP36-AS1/miR-221 axis on the proliferation and immune escape of bladder cancer cells.Methods:The expression difference of ZFP36-AS1 in bladder cancer tissues was analyzed by cBioPortal database. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to analyze the expression difference of ZFP36-AS1 in bladder cancer cell lines (J82, RT-4, MGH-U3, 5637). MGH-U3 cells were randomly divided into negative control (NC) group and ZFP36-AS1 group, which were transfected with pcDNA3.1-NC plasmid and pcDNA3.1-ZFP36-AS1 plasmid, respectively. Colony formation assay and flow cytometry were used to analyze the proliferation activity and cell cycle of MGH-U3 cells, respectively. T lymphocytes were co-cultured with MGH-U3 cells in each group, and the levels of interleukin-10 (IL-10), γ-interferon (IFN-γ), and interleukin-4 (IL-4) in the supernatants of each group were detected by enzyme-linked immunosorbent assay (ELISA). The dual-luciferase reporter gene assay verified the targeting relationship between ZFP36-AS1 and miR-221. The effect of ZFP36-AS1 on the expression of miR-221 in MGH-U3 cells was detected by RT-qPCR. Western blotting was used to detect the effect of ZFP36-AS1/miR-221 axis on the protein expression of CDK3, Cyclin C, CDK5, Cyclin D1 and Cyclin D3 in MGH-U3 cells.Results:Compared with normal bladder tissue, ZFP36-AS1 was abnormally low-expressed in bladder cancer tissue ( P<0.01). Compared with SV-HUC-1 cells, ZFP36-AS1 was abnormally low-expressed in bladder cancer cell lines (J82, RT-4, MGH-U3, 5637) ( P<0.01), and the expression was lowest in MGH-U3 cells ( P<0.01). The number of MGH-U3 cell colonies formed in the NC group and the ZFP36-AS1 group were (220.80±34.65) and (77.84±19.11), respectively, and the number of MGH-U3 cell colonies formed in the ZFP36-AS1 group was significantly down-regulated, the difference was statistically significant ( P<0.01). The proportions of G 0/G 1 phase cells in NC group and ZFP36-AS1 group were (48.04±2.89)% and (72.89±3.46)%, respectively, and the proportion of S phase cells were (35.38±2.98)% and (20.62±2.56)%, respectively. The proportion of G 2/M stage cells was (16.59±1.46)% and (6.48±1.50)%, respectively. The proportion of cells in G 0/G 1 phase were up-regulated in ZFP36-AS1 group ( P<0.01), and the proportion of cells in S phase and G 2/M phase were both down-regulated ( P<0.01). Compared with the NC group, the levels of IL-4 and IFN-γ in the ZFP36-AS1 group were significantly up-regulated ( P<0.01), and the level of IL-10 was significantly down-regulated ( P<0.01). ZFP36-AS1 can target miR-221 ( P<0.01). The relative expression of miR-221 in the NC group and the ZFP36-AS1 group was 6.84±1.35 and 1.00±0.21, respectively. Compared with the NC group, overexpression of ZFP36-AS1 could significantly inhibit the expression of miR-221 ( P<0.01). Compared with the NC group, the expressions of CDK3, Cyclin C, CDK5, Cyclin D1, and Cyclin D3 in the ZFP36-AS1 group were significantly decreased. Conclusion:ZFP36-AS1 is abnormally low-expressed in bladder cancer, and it reduces the proliferation activity of bladder cancer cells and inhibits their immune escape by inhibiting the expression of miR-221.

ObjectiveTo study the plasma pharmacokinetics and tissue distribution of five representative components in Wujiwan， and to illustrate the difference of metabolism and tissue distribution before and after compatibility. MethodHealthy male SD rats were divided into four groups， including Wujiwan group（A group， 62.96 g·L^-1）， Coptidis Rhizoma group（B group， 38.4 g·L^-1）， processed Euodiae Fructus group（C group， 5.88 g·L^-1） and fried Paeoniae Radix Alba group（D group， 18.68 g·L^-1）， with 65 rats in each group， and were administered the drugs according to the clinical dose of decoction pieces converted into the dose of the extracts. Then plasma， liver， small intestine and brain were taken at pharmacokinetic set time in each group after administration. Ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry was developed for the quantitative analysis of five representative components［berberine（Ber）， palmatine（Pal）， evodiamine（Evo）， rutecarpine（Rut） and paeoniflorin（Pae）］ in Wujiwan， their concentrations in plasma， liver， small intestine and brain were detected at different time， plasma samples were processed by protein precipitation， and tissue samples were pretreated by protein precipitation plus liquid-liquid extraction. Non-atrioventricular model was used to calculate the pharmacokinetic parameters of each component， and the parameters of each group were compared. ResultPharmacokinetic results of A group showed that area under the curve（AUC_0-t） of the five representative components were ranked as follows：Ber and Pal were small intestine>liver>blood， Evo and Rut were liver>small intestine>plasma， Pae was small intestine>plasma， which was not detected in the liver， no other components were detected in brain except for Ber. In comparison with plasma and other tissues， peak concentration（C_max） of Ber， Pal， Evo， and Rut were the highest and time to peak（t_max） were the lowest in the liver of A group. In plasma， the AUC_0-t and C_max of Evo and Rut were increased in A group compared with C group， t_max of Pea was elevated and its C_max was decreased in A group compared with D group. In the liver， compared with B-D groups， C_max values of 5 representative components except Pae were elevated， AUC_0-t of Pae was decreased and AUC_0-t of Evo and Rut were increased in the A group. In the small intestine， half-life（t_1/2） of each representative components in A group was elevated and t_max was decreased， and C_max of each representative ingredient except Pal was decreased， AUC_0-t values of Ber and Pal were increased， whereas the AUC_0-t values of Evo and Rut were decreased. ConclusionThe small intestine， as the effector organ， is the most distributed， followed by the liver. The pharmacokinetic parameters of the representative components in Wujiwan are changed before and after compatibility， which is more favorable to the exertion of its pharmacodynamic effects.

Osteoarthritis (OA) is a chronic degenerative joint disease whose main characteristic is the destruction of articular cartilage, causing pain and disability in patients and seriously affecting their quality of life. OA can be induced by a variety of causes, and pathological changes in articular cartilage are considered to be one of the key driving factors for the occurrence of OA. High mobility group box-1 protein (HMGB1), as a non-histone protein in eukaryotic cells, can participate in regulating the inflammation and apoptosis process of OA chondrocytes, thus leading to the occurrence of OA. This article reviews the research on the mechanism of HMGB1 in OA chondrocytes, with a view to providing new ideas for the clinical prevention and treatment of OA.
