OBJECTIVE: To investigate the relationship between single nucleotide polymorphism of gene and ischemic stroke and search for predisposing genes of ischemic stroke.DATA SOURCES: The Medline database was searched for articles of gene polymorphism of fibrinogen and ischemic stroke published from 1980 to 2005 with the key words of "stroke, plasma fibrinogen, polymorphism"in English. Meanwhile, Vip Information Database was also searched for literatures of gene polymorphism of fibrinogen and schemic stroke published between 1995 and 2005 with the key terms of "ischemic stroke, fibrinogen,gene polymorphism" in Chinese. Full-texts were gotten by correspondence with the authors.STUDY SELECTION: Included literatures were only case control study literatures. Literatures of contrast study, experience summary, individual case and so on were excluded.DATA EXTRACTION: Totally 50 articles of gene polymorphism of fibrinogen and ischemic stroke were retrieved. Twenty articles were accorded with inclusive criteria, and thirty articles were excluded.DATA SYNTHESIS: Level of plasma fibrinogen was co-affected by heredity and environment. Gene polymorphism of fibrinogen has important regulatory effects on the level of plasma fibrinogen. The fibrinogen accelerates thrombotic formation. As a result, the incidence rate of ischemic stroke increased by participating atherosclerosis, helping thrombocytic aggregation and changing the status of hemorheology. But definite mechanism and molecular function of gene polymorphism of fibrinogen deserved further research.CONCLUSION: The relationship between single nucleotide polymorphism of fibrinogen and ischemic stroke remains obscure. It also needs further study.

Objective To investigate the expression of CD40 protein in bladder urothelium cancer and to explore its correlation with clinical stage, pathological grades, cell apoptosis. Methods Expression of CD4o protein was evaluated by immunohistochemistry in paracancerous tissues (20 cases) and bladder urothelium cancer tissues (78 cases). Apoptosis of bladder urothelium cancer tissues was detected by Hoechst to determine the apoptotic rate (AR). Results The expression rate of CD40 protein was 2/20(10 %) in the cases of paracancerous tissues, 55/78(70.5%) in the cases of bladder urothelium cancer tissues, a statistically significant differences of CD40 staining was observed between paracancerous tissues and bladder urothelium cancer tissues (P ＜0.01). Overexpression of CD40 was strongly inversely related to the tumor grade and clinical stage; the positive group of CD40 protein was (12.60±0.38)%, the negative group of CD40 protein was (6.77±0.53)%, a statistically significant differences of apoptosis were observed between CD40 protein positive group and CD40 protein negative group (P ＜0.01). It showed CD40 protein might induce cell apoptosis. Conclusion Expression of CD40 protein is closely related with clinical stage, pathological grade and cell apoptotic rate and may offer reliable evidence for diagnosis, treatment and prognosis in bladder urothelium cancer.

Objective To study the clinical efficacy of epirubicin combined with paclitaxel in the treatment of three negative breast cancer.Methods 100 patients with breast cancer who were treated in Shanxi Cancer Hospital from January 2014 to December 2016 were selected as the research object in this study.They were randomly divided into the control group and the experimental group, with each group having a total of 50 patients.The control group was treated with epirubicin, and the experimental group was treated with epirubicin combined with paclitaxel.The short-term remission rate, Karnofsky score and the incidence of adverse symptoms were compared between the experimental group and the control group.Results After treatment, the Karnofsky score of the experimental group was(89.76±10.12), and the Karnofsky score of the control group was(71.23±11.67).The Karnofsky score of the experimental group was significantly higher than that of the control group (P<0.05).In the experimental group, the number of short-term remission was 44 cases, the short-term remission rate was 88.0%, and the number of patients in the control group in the recent remission was in the number of cases, the short-term remission rate was 72.0%, and the number of patients in the control group was about 36.The results showed that the short-term remission rate of the experimental group was significantly higher than that of the control group, with statistical difference (P<0.05).After treatment, there was no significant difference between the control group and the experimental group in the incidence of complications, which was not statistically significant.Conclusion The clinical effect of doxorubicin plus paclitaxel in the treatment of three negative breast cancer, can improve the remission rate in a large extent, improve the quality of life of patients, with further clinical promotion and application significance.

Chemotherapy resist is the problem for clinic,and some researches find that chemotherapy with anthracycline and oxaliplatin not only induces the tumor cell apoptosis,but also the celt immunogenic cell death (ICD) by inducing the tumor cell apoptosis and releasing three kinds of signals:exposure of calreticulin on the cell surface to stimulate the dendritic cell (DC) to engulf,and the secretion of adenosine triphosphate to recruit DC to enter into tumor bed,and the release of the high mobility group B1 to promote DC to steadily bind with dying tumor cell to induce specific T cell antitumor immune response.It is with great meaning to promote the chemotherapy protocol by studying the ICD induced by chemotherapy.

Objective To provide evidence for the application of nutritional intervention strategy by analyzing perioperative nutritional status of retroperitoneal liposarcoma patients.Methods 60retroperitoneal liposarcoma patients were divided into primary group (27 cases) and relapse group (33cases).These patients were put on nutritional risk evaluation using nutritional risk screening (2002)(NRS2002) within 24 hours of admission,and the serum albumin (ALB) value was recorded.Results Preoperative NRS2002 score showed that relapse group had a higher chance of cacotrophy.Serum albumin level from different time point showed that patients in relapse group were more prone to cacotrophy (respectively t =9.174,4.720,10.950,8.772,10.960,all P ＜ 0.05) and subject to slower recovery of gastrointestinal function [(86 ± 15) h vs.(61 ± 6) h] (t =7.903,P ＜ 0.05),prolonged antibiotic use [(15.5 ± 5.6) d vs.(7.3 ± 0.7) d],t =7.55,P ＜ 0.05),the average length of hospital stay was longer [(25.5±6.0) d vs.(14.1 ± 1.7)d] (t =9.571,P＜0.05),and higher inhospita cost [(13.2±5.6) × 104 yuan vs.(6.8 ± 0.9) × 104 yuan] (t =5.871,P ＜ 0.05).Though there was no difference between the two groups in incision complication rates (x2 =2.625,P ＞ 0.05)Conclusions Retroperitoneal liposarcoma patients has perioperative nutritional risk.Compared with the primary group,patients from relapse group have higher chance to got cacotrophy.NRS2002 scoring system is simple,it could be used in predicting nutritional risk for those patients.
