It was believed that there were only two patterns of cell death named after necrosis and apoptosis in the past.With the progress of research,scholars have found that there also existed other cell death patterns.However,the mechanisms and relationships between cell death patterns are still unclear,especially in the neuronal cell death.This review focuses on the cell death patterns and their relationships during ischemic stroke,in order to provide the theoretical basis and new ideas for the further study of neuronal cell death,and for the treatment of ischemic stroke.

Objective To compare the difference between intermittent epidural bolus(IEB) combined with patient controlled epidural analgesia(PCEA)and continuous epidural infusion(CEI)combined with PCEA mode in labor analgesia. Methods It was a retrospective cohort study ,which subjects were assigned to CEI+PCEA and IEB + PCEA group. Correlated data were collected to compare the effect of the two analgesic mode on perinatal events. Results There were less consumption of ropivacaine and sufentanil per hour ,less PCEA request and actual bolus in IEB + PCEA group. There were no significant difference between the delivery mode and the percentage of low Apgar score in neonates. Conclusion IEB+PCEA mode has better analgesic effect ,meanwhile doesn't disturb the delivery mode has no effect on the neonate outcome.

Objective To investigate the application of MR 3D-FLASH dynamic enhanced scanning in the breast diseases. Methods 108 women (35～76 years old,mean,47 years) with breast diseases confirmed by pathology were examined by using Siemens 1.0T superconducting MRI and double breast circles.Plain MR imaging performed first,then contrast-enhanced MR scans were followed with 3D FLASH sequence,and the images were subtracted.Results Among 108 cases,62 cases were benign and 46 cases were breast cancer,the diagnosing accurate rate of MR imaging was 81.5% compared with pathology pre-operation.Conclusion 3D-FLASH enhanced MR scan is the most valuable sequence in diagnosing breast lesions.

Objective To investigate the clinical features of primary retroperitoneal fibrosis (RPF), and to find out better method for diagnosis and therapy. Methods Nine patients with primary RPF in Peking Union Medical College Hospital since 1990 to 2003 were analyzed retrospectively. Results All patients had abnormal findings in CT or MRI, and 8 of them had chronic non-specific inflammation of the retroperitoneum in pathology. Six patients had renal involvement and 2 of them had severe renal failure. Eight of the patients had received therapy with corticosteroid or tamoxifene. Conclusions RPF is an uncommon collagen vascular disease characterized by a chronic non-specific inflammation of the retroperitoneum.Because of the atypical manifestations of RPF, awareness of the disease is important.CT and (or) open biopsy remains the gold standard for diagnosis.Management typically includes surgery and drug treatment.Corticosteroid therapy or more recently,tamoxifen has been used successfully. The clinical and radiographic improvement with drug treatment has been seen in several patients and confirmed the diagnosis,thereby early diagnosis and treatment can bring the patient more excellent renal and general outcome.

Objective : To systematically evaluate the incidence of suicide ideation among HIV/AIDS patients in China, so as to provide insights into prevention of suicidal behaviors among HIV/AIDS patients. Methods : All publications pertaining to suicide ideation were jointly retrieved in electronic databases from database creation to May 22, 2022, including CNKI, CMB, Wanfang Data, VIP, PubMed and Web of Science. The quality of literatures was evaluated using the 11 quality indicators for cross-sectional studies recommended by the United States Agency for Healthcare Research and Quality (AHRQ), and a meta-analysis was performed using the software Stata 16.0. The stability of the study results was evaluated using sensitivity analysis, and the publication bias was evaluated using Begg's test. Results : A total of 1 557 publications were screened and 32 literatures covering 12 917 HIV/AIDS patients were included in the final analysis, including 21 Chinese publications and 11 English publications, and 19 high-quality publications and 13 moderate-quality publications. Meta-analysis showed that the incidence of suicide ideation was 30.3% (95%CI: 23.2%-37.4%) among HIV/AIDS patients in China, and subgroup analysis showed higher incidence of suicide ideation in unemployed HIV/AIDS patients than in employed patients (P<0.05). Sensitivity analysis showed stable study results, and Begg's test revealed no significant publication bias. Conclusions The incidence of suicide ideation is 23.2% to 37.4% among HIV/AIDS patients in China. High attention paid to psychological health and early psychological interventions are required to prevent the development of suicide ideation.

Objective: To evaluate the efficacy and safety of overlapping biodegradable polymer sirolimus-eluting stents (EXCEL) in treating the patients with diffuse long coronary lesions (total stent length for per lesion>60 mm).
Methods: A total of 71 patients with diffuse long coronary lesions with overlapped EXcellstents implantation in our hospital from 2010-08 to 2012-05 were retrospectively studied. The average age of patients was (62.85 ± 10.26) years and 74.56%with male gender. The clinical endpoints were the major adverse cardiac events (MACE) at in-hospital time and at 2-year follow-up period.
Results: The average target lesion was implanted (2.61 ± 0.52) stents, the mean stent diameter was (3.21 ± 0.35) mm and the length was (73.34 ± 13.11) mm. The in-hospital MACE rate was 4.23%, the 2-year target vessel revascularization and MACE rates were 9.86%and 18.31%respectively. Cox regression analysis indicated that smoking (HR 12.102, 95%CI 1.460-100.309, P=0.021), previous history of MI (HR 11.948, 95%CI 1.144-124.726, P=0.038) and previous history of PCI (HR 0.097, 95%CI 0.010-0.990, P=0.049) were the independent risk factors of out of hospital MACE occurrence.
Conclusion: EXcellstent implantation was safe and effective for treating the patients with diffuse long coronary lesions, the long term follow-up study revealed that there was the increased risk for MACE and target vessel revascularization.

ObjectiveTo study the role and mechanism of resisitin in prophylactic and therapeutic treatments of rosiglitazone,a specific peroxisome proliferator-activated receptor-γ(PPARγ) ligand,in rats with severe acute pancreatitis (SAP) and pancreatitis-associated pulmonary injury.MethodsThe levels of amylase ( AMY ),Resistin,TNF-α,IL-1 β and C reactive protein (CRP) in blood plasma,lung myeloperoxidase ( MPO ) activity,pancreas/body weight ratio and lung wet/dry weight ratio were evaluated.Pancreatic and pulmonary pathology were observed.The expression of resistin in pancreas was detected byimmunohistochemistry.The gene expression of resistin mRNA was investigated by real-time PCR.ResultsBoth prophylactic and therapeutic treatments with rosiglitazone could obviously ameliorate the levels of AMY,resistin,TNF-αt,IL-1β and CRP ( all P ＜ 0.01 ).Compared with the control group,both prophylactic and therapeutic treatment groups were higher( all P ＜ 0.01 ).The prophylactic treatment group was not different from the therapeutic treatment group.Both prophylactic and therapeutic treatments with rosiglitazone could significantly reduce pancreas/body weight ratio,pancreatic pathology,MPO,pulmonary pathology ( all P ＜ 0.01 ).Compared with the SAP group,the expression of resistin mRNA in the prophylactic and therapeutic treatment groups were obviously decreased.ConclusionRosiglitazone could obviously ameliorate pancreatitis and pulmonary injury induced by L-arginine.

Purpose To investigate the effect of small interfering RNA on the increase of myocyte enhancer factor 2A(MEF2A) expression in PC12 cells exposed to hypoxia.Methods PC12 cells were cultured under normal conditions or were exposed to hypoxic conditions.Small interfering RNA targeted MEF2A gene (MEF2A-siRNA) was chemically synthesized. Eukaryocytic expression vector was built and transfected into PC12 cells with liposome. The expression of MEF2A mRNA was detected by real-time PCR. Western blot was used to detect the MEF2A protein.Results Compared with normal control(2~(-△△CT)=1.01±0.02), the mRNA level of MEF2A gene in PC12 cells with the treatment of MEF2A-siRNA was down-regulated significantly by 88%(2~(-△△CT)=0.12±0.03, P＜0.01).The expression of MEF2A protein in hypoxia-treated PC12 cells was markedly higher than that of normal control(98.4±11.7 and 47.5±7.6,P＜0.01).However, MEF2A-siRNA could significantly suppress the increase of MEF2A protein (P＜0.01).Conclusion MEF2A gene silence induced by siRNA might inhibit the increase of MEF2A protein by hypoxia in PC12 cells.
