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.

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: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.

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.

The purpose of this study was to understand the prevalence of Neoehrlichia mikurensis in rodents in Yunnan commensal rodent plague foci.Lianghe Country,Mangshi City,and Mile City in Yunnan Province were chosen as sampling sites,where rodents were captured with dead-traps.The N.mikurensis groEL gene in rodent spleen samples was detected with nested PCR,and the positive products were sequenced with Sanger bidirectional assays.The infection rate of N.mikurensis a-mong plague foci,habitats,species,and sexes was compared with Chi-square tests or Fisher's exact probability method.Of 656 rodent spleen samples,12 N.mikurensis positive samples were detected in R.tanezumi,R.sladeni,N.confucianus,and B.bowersi.The positivity rate was 1.83％.No significant difference in the N.mikurensis positivity rate was observed a-mong plague foci,habitats,species,and sexes(P＞0.05).Genetic evolution analysis of the groEL gene indicated that the se-quence similarity of nucleic acid sequences in 12 positive samples was 99.5％-100％,and the nucleic acid sequences of N.mikurensis were in the same branch,belonging to cluster Ⅳ.Thus,four species of rodents were found to have low frequency infection with N.mikurensis in Yunnan commensal rodent plague foci.

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 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.

Objective:To investigate the safety and efficacy of mitoxantrone liposome in the treatment of children with high-risk acute myeloid leukemia(AML).Methods:The children with high-risk AML who received the mitoxantrone liposome regimen at Wuhan Children's Hospital from January 2022 to February 2023 were collected as the observation group,and the children with high-risk AML who received idarubicin regimen were enrolled as controls,and their clinical data were analyzed.Time to bone marrow recovery,the complete remission rate of bone marrow cytology,the clearance rate of minimal residual disease,and treatment-related adverse reactions were compared between the two groups.Results:The patients treated with mitoxantrone liposome showed shorter time to recovery of leukocytes(17 vs 21 day),granulocytes(18 vs 24 day),platelets(17 vs 24 day),and hemoglobin(20 vs 26 day)compared with those treated with idarubicin,there were statistical differences(P＜0.05).The effective rate and MRD turning negative rate in the observation group were 90.9％and 72.7％,respectively,while those in the control group were 94.1％and 76.4％,with no statistical difference(P＞0.05).The overall response rate of the two groups of patients was similar.Conclusion:The efficacy of mitoxantrone liposome is not inferior to that of idarubicin in children with high-risk AML,but mitoxantrone liposome allows a significantly shorter duration of bone marrow suppression and the safety is better.

Objective:To summarize the clinical features of reversible posterior encephalopathy syndrome(PRES)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in children.Methods:The clinical data of six children who developed PRES after undergoing allo-HSCT in the Department of Hematology of Wuhan Children's Hospital from June 2016 to December 2022 were retrospectively analyzed,and their clinical characteristics,imaging examination,laboratory examination,and treatment regression were summarized.Results:Among 281 children underwent allo-HSCT,6 cases(2.14％)developed PRES,with a median age of 5.1(1.5-9.7)years old.4 cases underwent related haploidentical donor transplantation,and 2 cases underwent sibling allografting and unrelated donor allografting donor transplantation,respectively.All six children had an acute onset of illness,with clinical manifestations of nausea and vomiting,seizures,psychiatric disorders,visual disturbances.The five cases elevated blood pressure.All children with PRES were treated with oral immunosuppressive drugs during seizures,and 3 cases were combined with different degrees of graft-versus-host disease.Most of the children showed effective improvement in clinical symptoms and imaging after adjusting/discontinuing suspected medications(cyclosporine,etc.)and symptomatic supportive treatments(oral antihypertensive,diazepam for antispasmodic,mannitol to lower cranial blood pressure),and one of them relapsed more than 8 months after the first seizure.Conclusion:PRES is rare after hematopoietic stem cell transplantation in children,and its onset may be related to hypertension,cytotoxic drugs,graft-versus-host disease,etc.Most of them can be recovered after active treatment,but not completely reversible,and the prognosis of those who combined with TMA is poor.
