Acute lung injury (ALI) is a significant complication of sepsis, characterized by high morbidity, mortality, and poor prognosis. Neutrophils, as critical intrinsic immune cells in the lung, play a fundamental role in the development and progression of ALI. During ALI, neutrophils generate neutrophil extracellular traps (NETs), and excessive NETs can intensify inflammatory injury. Research indicates that Taohe Chengqi decoction (THCQD) can ameliorate sepsis-induced lung inflammation and modulate immune function. This study aimed to investigate the mechanisms by which THCQD improves ALI and its relationship with NETs in sepsis patients, seeking to provide novel perspectives and interventions for clinical treatment. The findings demonstrate that THCQD enhanced survival rates and reduced lung injury in the cecum ligation and puncture (CLP)-induced ALI mouse model. Furthermore, THCQD diminished neutrophil and macrophage infiltration, inflammatory responses, and the production of pro-inflammatory cytokines, including interleukin-1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α). Notably, subsequent experiments confirmed that THCQD inhibits NET formation both in vivo and in vitro. Moreover, THCQD significantly decreased the expression of peptidyl arginine deiminase 4 (PAD4) protein, and molecular docking predicted that certain active compounds in THCQD could bind tightly to PAD4. PAD4 overexpression partially reversed THCQD's inhibitory effects on PAD4. These findings strongly indicate that THCQD mitigates CLP-induced ALI by inhibiting PAD4-mediated NETs.

Nonalcoholic steatohepatitis （NASH） is a chronic liver disease with the main pathological features of hepatic steatosis， inflammatory cell infiltration， and interstitial fibroplasia， and it is an important risk factor for liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. NOD-like receptor protein 3 （NLRP3） inflammasome is the core of innate immunity， and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH， which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine （TCM） and TCM compound prescriptions can improve oxidative stress， regulate lipid metabolism， and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect， while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome， in order to provide ideas for the clinical TCM treatment of NASH， as well as reference targets and research directions for the research and development of new TCM drugs.

Objective: To investigate the characteristics of temporal and spatial distribution of tuberculosis epidemics in Shache County, Kashgar Region, Xinjiang. Methods: Information on the incidence of tuberculosis in Sacha County from 2019—2021 was collected and spatiotemporally analyzed by applying the circular distribution method, local spatial autocorrelation analysis, hot and cold spot analysis, directional distribution and spatial center of gravity methods. Results : The total number of tuberculosis cases in Shache County in 2019—2021 was 8 345, of which 52.03%were male and 47.97% were female, and the patients were predominantly 60-75 years old. The number of reported incidences of TB in Tagarqi Township, Shache Township, and Chajek Township ranked among the top three in the county. Spring and summer were the disease-prone seasons for TB, and mid-March to mid-July was the period of high disease incidence. Misha Township and Ishkuli Township are the “high and high” gathering areas, while the “low and low” gathering areas are mainly concentrated in Khoshrav Township and Karasu Township. The hotspots of TB incidence in Shache county were Tagarqi township, Misha township, and Ishkuli township. During the study period, the center of gravity of TB incidence in Shache county of Kashgar area gradually shifted from the southwest to the northeast. Conclusion In Shache county, there is a certain degree of aggregation of tuberculosis outbreaks, with more men than women reporting illnesses, a larger proportion of older people, and a strong seasonal incidence of the disease, with Mixia township and Ishikuli township being the key areas of incidence. Relevant departments should continue to strengthen the disease surveillance of key populations and regions during the high incidence of tuberculosis, and take appropriate intervention measures to reduce the risk of tuberculosis transmission.

Objective To explore the genes related to the pathogenesis of polycystic ovary syndrome(PCOS)through bioinformatics methods and verify them in ovarian granulosa cells,providing a reference for screening potential molecular markers of PCOS.Methods The GSE34526 and GSE137684 datasets were re-spectively used as the training set and validation set.The inflammation-related genes potentially associated with the onset of PCOS were explored through differential expression analysis and weighted gene co-expres-sion network analysis.Subsequently,their predictive value was verified through the receiver operating charac-teristic(ROC)curve.Thirty patients with PCOS(the PCOS group)and 27 patients without PCOS(the con-trol group)who were treated in Affiliated Hospital of Youjiang Medical University for Nationalities were se-lected as the research objects.RT-qPCR was applied to verify the expression level of core genes in granular cells.Spearman correlation and multiple linear regression were used to analyze the correlation between the ex-pression level of core genes and various clinical parameters,and the ROC curve was used to analyze the diag-nostic efficacy of the expression level of core genes for PCOS.Finally,the protein expression level of core genes was verified on animal models.Results A total of 1 888 differentially expressed genes,89 module-relat-ed genes and 366 inflammatory response-related genes were identified.The core gene phosphatidylinositol-4,5-diphosphate 3-kinase catalytic subunit γ(PIK3CG)was ultimately obtained by taking co-expressed genes and verifying with the ROC curve.RT-qPCR results showed that the expression level of PIK3CG in granulosa cells of the PCOS group was higher than that of the control group(P<0.05).Spearman correlation analysis showed that the expression level of PIK3CG was positively correlated with BMI,testosterone(T),fasting in-sulin(FINS),and insulin resistance index(HOMA-IR,P<0.05).Multivariate linear regression analysis showed that FINS,HOMA-IR and BMI were increased with the increasing of PIK3CG expression level(P<0.05).ROC curve analysis showed that the area under the curve for diagnosing PCOS patients with PIK3CG mRNA expression levels in granulosa cells was 0.659 3.The immunohistochemical results showed that the ex-pression of PIK3CG protein in the ovarian tissues of mice in the PCOS group was significantly increased.Con-clusion PIK3CG may be potentially associated with the pathogenesis of PCOS.

The doctor-patient relationship is a set of social relationships based on shared interests， mutual trust， and emotional bonds， to relieve illnesses and promote health. However， the doctor-patient relationship often falls into tensions and conflicts. How to build a trusting and harmonious doctor-patient destiny community has become one of the most important issues of concern to the whole society. Based on the biopsychosocial concept of disease， the emotion management technique （EMT） emphasizes that doctors take the patient’s emotion as a clue in clinical diagnosis and treatment， regard emotions as one of the important indicators for disease diagnosis， understand the emotional events behind the disease， and provide patients with appropriate empathy and emotional management， so as to provide clinical methods for managing diseases and building a trusting and harmonious doctor-patient relationship.

BACKGROUND:Bone relies on the close connection between blood vessels and bone cells to maintain its integrity.Bones are in a physiologically hypoxic environment.Therefore,the study of angiogenesis and osteogenesis in hypoxic environment is closer to the microenvironment in vivo. OBJECTIVE:To explore the influence of Wenshen Tongluo Zhitong(WSTLZT)formula on H-type bone microvascular endothelial cell/bone marrow mesenchymal stem cell co-culture system in hypoxia environment and its related mechanism. METHODS:Enzyme digestion method and flow sorting technique were used to isolate and identify H-type bone microvascular endothelial cells.Mouse bone marrow mesenchymal stem cells were isolated and obtained by bone marrow adhesion method.H-type bone microvascular endothelial cell/bone marrow mesenchymal stem cell hypoxic co-culture system was established using Transwell chamber and anoxic culture workstation.WSTLZT formula powder was used to intervene in each group at a mass concentration of 50 and 100 μg/mL.The angiogenic function of H-type bone microvascular endothelial cells in the co-culture system was evaluated by scratch migration test and tube formation test.The osteogenic differentiation ability of bone marrow mesenchymal stem cells in the co-cultured system was evaluated by alkaline phosphatase staining and alizarin red staining.The protein and mRNA expression changes of PDGF/PI3K/AKT signal axis related molecules in H-type bone microvascular endothelial cells in the co-cultured system were detected by Western Blotting and q-PCR,respectively. RESULTS AND CONCLUSION:(1)Compared with the normal oxygen group,the scratch mobility and new blood vessel length of H-type bone microvascular endothelial cells were significantly higher(P<0.05);the osteogenic differentiation capacity of bone marrow mesenchymal stem cells was higher(P<0.05);the expression of PDGF/PI3K/AKT axis-related molecular protein and mRNA increased(P<0.05)in the hypoxia group.(2)Compared with the hypoxia group,scratch mobility and new blood vessel length were significantly increased in the H-type bone microvascular endothelial cells(P<0.05);bone marrow mesenchymal stem cells had stronger osteogenic function(P<0.05);the expression of PDGF/PI3K/AKT axis-related molecular proteins and mRNA further increased(P<0.05)after treatment with different dose concentrations of WSTLZT formula.These findings conclude that H-type angiogenesis and osteogenesis under hypoxia may be related to the PDGF/PI3K/AKT signaling axis,and WSTLZT formula may promote H-type vasculo-dependent bone formation by activating the PDGF/PI3K/AKT signaling axis,thereby preventing and treating osteoporosis.

Objective To compare the safety of laparoscopic pancreatoduodenectomy(LPD)and open pancreatoduodenectomy(OPD)and analyze the learning curve and safety at different stages of LPD.Methods A retrospective analysis was conducted on the clinical data of 50 LPD patients and 54 OPD patients in the Department of Hepatopancreatobiliary Surgery of Suzhou Hospital Affiliated to Nanjing Medical University from January 2020 to June 2024,and intraoperative and postoperative conditions were compared.The Cumulative Sum(CUSUM)analysis method was used to analyze the technical nodes of the LPD learning curve.Results There were no significant differences in operation time and intraoperative blood loss between the LPD group and the OPD group(P＞0.05).There was also no significant difference in the incidence rates of pancreatic fistula(grade B and C),delayed gastric emptying,postoperative bleeding,biliary fistula and intra-abdominal infection between the LPD group and the OPD group(P＞0.05).A time series plot of operation time was drawn based on the patient's operation time and surgical sequence,yielding a fitted curve.Curve analysis showed initial stage and stable stage were finished at the 17th and 24th cases.The LPD learning curve could be divided into three stages:stage Ⅰ characterized as the initial stage(cases 1 to 17),stage Ⅱ characterized as the stable stage(cases 18 to 24),and stage Ⅲ characterized as the proficient stage(cases 25 to 50).The operation time in stages Ⅱ and Ⅲ was significantly shorter than that in stage Ⅰ,and the intraoperative blood loss in stage Ⅰ was significantly higher than that in stage Ⅲ(P＜0.05).There was no significant difference in the incidence of complications among the three stages(P＞0.05).Conclusion LPD and OPD show no significant differences in indications and safety.The LPD learning curve can be divided into three stages.As the number of surgeries completed increa-ses,the operation time of physicians gradually shortens,and the incidence of complications of patients gradually decreases.

Objective To investigate the safety and efficacy of selective hepatic inflow occlusion in laparoscopic hepatectomy.Methods A retrospective analysis was conducted on the clinical data of 64 patients who underwent laparoscopic hepatectomy.Based on the different methods of hepatic in-flow occlusion,the patients were divided into Pringle occlusion group with 31 patients(using inter-mittent Pringle's maneuver)and selective occlusion group with 33 patients(using selective hepatic inflow occlusion).The general,intraoperative,and postoperative data were compared between the two groups.Results There were no statistically significant differences in general data,operative time,intraoperative blood loss,central venous pressure,and mean arterial pressure between the two groups(P＞0.05).On postoperative day 3,the levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),and total bilirubin(TBil)in the selective occlusion group were lower than those in the Pringle occlusion group(P＜0.05).There were no statistically significant differences in length of hospital stay and postoperative complication rates between the two groups(P＞0.05).Sub-group analysis showed that in patients undergoing laparoscopic hemihepatectomy,the AST and ALT levels on postoperative day 3 were lower in the selective occlusion group than in the Pringle occlusion group(P＜0.05).In patients undergoing laparoscopic liver segmentectomy,the TBil level on postop-erative day 3 was lower in the selective occlusion group than in the Pringle occlusion group(P＜0.05),but there were no statistically significant differences in AST and ALT levels between the two groups(P＞0.05).Conclusion Selective hepatic inflow occlusion demonstrates good safety and efficacy in laparoscopic hepatectomy.It can significantly reduce postoperative liver function damage,espe-cially in patients undergoing hemihepatectomy.

Objective To systematically review the manage effects of prescription refill in hypertension management in our country,and to provide suggestions for chronic disease policies.Methods Web of Science,PubMed,Embase,Cochrane Library,SinoMed,CNKI,WanFang Data,VIP databases were electronically searched to collect randomized controlled trails(RCTs)of prescription refill services for hypertension management from inception to March 31,2024.Two reviewers independently screened the literature,extracted data and assessed the risk of bias of the included studies.Meta-analysis was conducted by using RevMan 5.3 software.Results A total of 14 RCTs involving 1,386 patients were included.Meta-analysis results showed that systolic blood pressure[MD=-9.19,95％CI(-12.20,-6.17),P<0.001],diastolic blood pressure[MD=-4.98,95％CI(-6.71,-3.26),P<0.001]in experimental group was significantly lower than the control group.Patient compliance score[SMD=2.05,95％CI(0.44,3.66),P=0.01],compliance rate[RR=1.15,95％CI(1.08,1.23),P<0.001],patient satisfaction[RR=1.28,95％CI(1.16,1.42),P<0.001]in experimental group were significantly higher than the control group.Conclusion the prescription refill for chronic diseases is rapidly developing in our country,and has achieved remarkable results in the management of hypertension patients.In the future,it is necessary to further promote the safe,effective and standardized implementation of prescription refill services,and carry out high-quality service models with multi-disciplinary participation.

Objective To investigate the expression levels of serum hemoglobin β(HBB)in hepatocellular carcinoma(HCC)patients and its correlation with topoisomeraseⅡα(TOP2A)gene.Methods A total of 48 HCC patients visited the Second Affiliated Hospital of Nantong University from August 2023 to September 2024 were selected as the HCC group,and 32 healthy individuals who underwent physical examination during the same period were selected as the healthy control group.Their blood samples were collected,and the ex-pression levels of serum HBB and TOP2A genes were detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR).Then,the relationship between the expression of HBB gene and clinicopathological parameters of the patients was ana-lyzed.The Kaplan-Meier Plotter database was used to evaluate the relationship between the expression of HBB gene and the prognosis of HCC.The diagnostic value of the expressions of serum HBB and TOP2A genes for HCC was assessed by the receiver operating charac-teristic(ROC)curve.Spearman rank correlation analysis was used to evaluate the correlation between the expressions of serum HBB and TOP2A genes in HCC patients.The regulatory effect of HBB gene on TOP2A gene was verified by the cell experiment.Results The expression levels of serum HBB gene in HCC patients(0.097[0.055,0.155])were significantly lower than that in healthy controls(1.029[0.625,1.434],U=19,P＜0.001).The expression levels of serum TOP2A gene in HCC patients(1.810[0.825,3.623])were significantly higher than that in healthy controls(1.047[0.604,1.364],U=495,P=0.007).The expression level of serum HBB gene in HCC patients was significantly negatively correlated with that of TOP2A gene(ρ=-0.384,P=0.007).The analysis results of clinicopathological parameters showed that the expression level of HBB gene was only related to tumor size(χ2=4.090,P＜0.05).The Kaplan-Meier survival analysis showed that the 5-year overall survival rate of the patients with low expression of HBB gene was signifi-cantly lower than that with high expression(HR=0.680,95%CI:0.470-0.970,P＜0.05).The analysis of the ROC curve showed that the area under the ROC curve(AUCROC)of HBB gene in diagnosing HCC was 0.987(95%CI:0.963-1.000).When the cut-off value was 0.228,its sensitivity was 100%and specificity was 97%.The AUCROC of TOP2A gene for the diagnosis of HCC was 0.677(95%CI:0.559-0.797).When the cut-off value was 1.285,its sensitivity was 65%and specificity was 75%.The combined detection of HBB and TOP2A genes for the diagnosis of HCC had an AUCROC of 0.988(95%CI:0.965-1.000).When the cut-off value was 0.657,its sensitivity was 100%and specificity was 97%.The cell experiment results showed that the overexpression of HBB gene could inhibit the expression of TOP2A gene,while the knockout of HBB gene had the opposite effect.Conclusion HBB gene is lowly expressed in the serum of HCC patients and is significantly negatively correlated with the expression of TOP2A gene.
