BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To investigate the effect and mechanism of leucine zipper/EF-hand-containing transmembrane protein 1(LETM1)on proliferation,migration,apoptosis,osteogenic differentiation,and tumorigenesis in vivo of human osteosarcoma MG63 and 143B cells.Methods The osteosarcoma MG63 and 143B cells were divided into blank control group(without adenovirus infection),negative control group(sh-NC group,infected with RNAi negative control virus),and LETM1 knockdown group(sh-LETM1 group,infected with sh-LETM1 adenovirus).Western blotting was performed to detect LETM1 expression in normal human osteoblasts hFOB1.19 and osteosarcoma cells,and to verify the knockdown effect of adenovirus;cell clone formation assays and CCK-8 method were used to detect the proliferation of MG63 and 143B cells;wound-healing assay and Transwell assay were used to test cell migration;DAPI staining and Annexin V-APC/7-AAD flow cytometry double staining were used to detect the apoptosis of MG63 and 143B cells;alkaline phosphatase(ALP)staining and Alizarin Red S staining were used to evaluate early and late osteogenic differentiation of MG63 and 143B cells.Ten nude mice were divided into sh-NC group(n=5,injected subcutaneously into nude mice with 143B cells infected with RNAi negative control virus)and sh-LETM1 group(n=5,injected subcutaneously into nude mice with 143B cells infected with sh-LETM1 adenovirus),and nude mice subcutaneous tumor formation assay was used to examine the in vivo tumor-forming ability of 143B cells in each group.Results Western blotting showed that the expression of LETM1 protein in osteosarcoma MG63 and 143B cells was significantly higher than that in human normal osteoblasts hFOB1.19(P<0.05),and that the expression of LETM1 protein was markedly reduced after injection with sh-LETM1 adenovirus in MG63 and 143B cells.The results of cell clone formation assay and CCK-8 assay indicated that in MG63 and 143B osteosarcoma cells,the clone formation ability and proliferation ability were significantly reduced in sh-LETM1 group compared with sh-NC group and blank control group(P<0.01).The results of wound-healing assay and Transwell assay demonstrated that in MG63 and 143B osteosarcoma cells,the cell migration rate in sh-LETM1 group was significantly lower than that in sh-NC group and blank control group(P<0.01).DAPI staining and flow cytometry results revealed that the apoptosis rate in sh-LETM1 group was significantly higher than those in MG63 and 143B osteosarcoma cells in sh-NC group(P<0.01).Alkaline phosphatase staining and Alizarin red S staining experiments showed more stained areas and calcium salt nodules in MG63 and 143B osteosarcoma cells in sh-LETM1 group than those in sh-NC group and blank control group.The results of the subcutaneous tumor formation assay in nude mice indicated that subcutaneous tumor formation ability was reduced in 143B sh-LETM1 group compared with 143B sh-NC group.Conclusion LETM1 promotes the proliferation,migration and in vivo tumor formation of MG63 and 143B osteosarcoma cells and the mechanism may be related to the inhibition of apoptosis and osteogenic differentiation.

Objective To explore the changes in the expression of glucose transporters 1/4(GLUT1/4)and Sirtuins in the retina of rats with diabetes.Methods Twenty 8-week-old healthy male Sprague-Dawley rats were randomly divid-ed into normal control and diabetic groups.Rats in the diabetic group received a disposable intraperitoneal injection of 60 mg·kg-1 streptozotocin to induce the diabetes model,while rats in the normal control group were injected with an equiva-lent amount of solvent.Body weight and blood glucose were measured at 2-week intervals.At 12 weeks after modeling,color Doppler ultrasound was applied to detect blood flow parameters in the central retinal artery(CRA)of rats;after an-esthetizing rats with sodium pentobarbital,eyeballs were harvested,and the pathological changes of rat retinal tissue were observed by hematoxylin & eosin(HE)staining.The expression of messenger ribonucleic acid(mRNA)for GLUT 1/4 and Sirtuins in the retina of rats were detected by immunohistochemical staining,Western blot and quantitative of reverse tran-scription polymerase chain reaction(qRT-PCR),respectively.Results At 12 weeks after modeling,compared with the normal control group,peak systolic velocity and end diastolic velocity were significantly lower in CRA of rats in the diabetic group(both P＜0.001);there were no significant differences in resistance index and pulsatility index(both P＞0.05).The HE staining results at 12 weeks after modeling showed that rats in the normal control group had clear structure in each layer of retinal tissues,closely and regularly arranged cells,and no obvious pathological changes;rats in the diabetic group showed decreased retinal thickness,blurred boundary of each layer,disordered structure and reduced cell number.Immu-nohistochemical staining at 12 weeks after modeling showed that GLUT 1 was mainly located in the retinal pigment epithelial layer of rats,and GLUT 4 was located in the ganglion cell layer,inner plexiform layer and photoreceptor layer.Western blot results showed that the relative expression of GLUT1 and GLUT 4 protein in the diabetic group were lower than that in the normal control group(both P＜0.05),and the relative expression of SIRT1-SIRT7 protein in the retina of rats in the di-abetic group were lower than those of the normal control group(all P＜0.05).qRT-PCR showed a decreased relative ex-pression of SIRT1-SIRT7 mRNA in the retina of rats in the diabetic group compared with that of the normal control group(allP＜0.01).Conclusion Diabetes can cause altered expression of GLUT1/4 and Sirtuins in the retinal tissue of rats,and GLUT1/4 and Sirtuins may be involved in the occurrence and development of diabetic retinopathy.

Objective:To describe and analyze suicide risk of patients with schizophrenia,major depressive disorder,and bipolar disorder.Methods:A total of 2 016 patients with schizophrenia,903 patients with major de-pressive disorder,and 381 patients with bipolar disorder from inpatients,clinics,or communities who met the diag-nostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition were recruited.All patients were interviewed by psychiatrists using the Mini International Neuropsychiatric Interview to diagnose mental disor-ders and assess suicide risk,as well as Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)to as-sess symptoms.Differences and risk factors of suicide risk among three types of mental disorders were explored u-sing multivariate logistic regression analysis.Results:In the past one month,37 patients with schizophrenia(1.8％),516 patients with major depressive disorder(57.1％),and 102 patients with bipolar disorder(26.8％)had suicide risk.Compared with patients with schizophrenia,suicide risk in patients with major depressive disorder(OR=36.50)and bipolar disorder(OR=20.10)increased.Female(OR=1.87),smoking(OR=1.76),family history of suicide(OR=5.09),higher score of CRDPSS hallucination(OR=1.80),and higher score of CRDPSS depression(OR=1.54)were risk factors of suicide risk of patients.Conclusions:Suicide risk of patients with ma-jor depressive disorder and bipolar disorder is higher than that of patients with schizophrenia.In clinical practice,it is important to regularly assess suicide risk of patients.Patients who experience symptoms of hallucination and de-pression should be paid more attention to.

Lung cancer is the leading cause of cancer-related deaths worldwide, especially non-small cell lung cancer (NSCLC). With the popularization of low-dose CT and the improvement of people’s awareness of physical examinations, the number of detected pulmonary nodules is gradually increasing, and there is a greater demand for standardized diagnostic and treatment guidelines. On April 23, 2024, the National Comprehensive Cancer Network updated its clinical practice guidelines for NSCLC to the version 5. Compared with the version 5 in 2023, the version 5 in 2024 updates focus on diagnostic evaluation, perioperative systemic therapy, treatment of advanced NSCLC, and molecular marker testing, which will be interpreted in this article with the aim of providing the latest guidance and reference for the diagnosis and treatment of lung cancer in China.

Objective Studies on the relationship between iodine,vitamin A(VA),and vitamin D(VD)and thyroid function are limited.This study aimed to analyze iodine and thyroid-stimulating hormone(TSH)status and their possible relationships with VA,VD,and other factors in postpartum women. Methods A total of 1,311 mothers(896 lactating and 415 non-lactating)from Hebei,Zhejiang,and Guangxi provinces were included in this study.The urinary iodine concentration(UIC),TSH,VA,and VD were measured. Results The median UIC of total and lactating participants were 142.00 μg/L and 139.95 μg/L,respectively.The median TSH,VA,and VD levels in all the participants were 1.89 mIU/L,0.44 μg/mL,and 24.04 ng/mL,respectively.No differences in the UIC were found between lactating and non-lactating mothers.UIC and TSH levels were significantly different among the three provinces.The rural UIC was higher than the urban UIC.Obese mothers had a higher UIC and a higher prevalence of excessive TSH.Higher UICs and TSHs levels were observed in both the VD deficiency and insufficiency groups than in the VD-sufficient group.After adjustment,no linear correlation was observed between UIC and VA/VD.No interaction was found between vitamins A/D and UIC on TSH levels. Conclusion The mothers in the present study had no iodine deficiency.Region,area type,BMI,and VD may be related to the iodine status or TSH levels.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

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.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
