Objective To investigate the episode of ischemic stroke in patients with serum homocysteine (Hcy),erythropoietin and its clinical significance (EPO)levels.Methods Detected 120 cases of first ischemic stroke patients serum Hcy,EPO lev-els and test results with 120 cases over the same period outpatient healthy compare.Used Logistic regression analysis and Pearson correlation analysis to determine the relationship between serum Hcy,EPO levels and ischemic stroke,ROC curve a-nalysis of clinical characteristics of Hcy and EPO.Results Serum Hcy,EPO level of ischemic stroke were respectively 23.1 ±12.6μmol/L and 32.4±11.2 mIU/L.The control level were respectively 10.4±2.8μmol/L and 17.6±5.2 mIU/L.Is-chemic stroke group were significantly higher.The results had statistical significance (P<0.05 or<0.01).Pearson correla-tion analysis showed that ischemic stroke serum Hcy levels and EPO levels were positively correlated (r=0.369,P<0.05). Logistic regression analysis showed that Ischemic stroke was positively related to serum Hcy level (P<0.05),and were not related to EPO (P>0.05).Conclusion The serum Hcy,elevated EPO levels associated with ischemic stroke.Serum Hcy is an independent risk factor of ischemic stroke.

Objective:To study the clinical effect of early postoperative enteral nutrition and parenteral nutrition after radical ex-cision of gastric cancer to provide a better way of treating gastric cancers. Methods:Retrospective analysis of 140 gastric cancer pa-tients who were admitted to the PLA General Hospital between February 2009 and February 2011 was conducted. These patients were randomized into two groups based on the clinical trial, i.e., 70 in the control group received an intravenous parenteral nutrition for the treatment, and for the other 70 in the observation group, jejunostomy was done 1 to 5 days after the radical surgery by using Supportan as the enteral nutritional agent with a dose of at TPF-T 500 mL/d to 1 000 mL/d. The postoperative long-term survival rate of the pa-tients, the serum albumin, hemoglobin, alanine aminotransferase, aspartate aminotransferase levels before and after the treatment, as well as the situation of IgA, IgG, IgM and CD4+cells, NK cells, and B lymphocytes in the blood at the first and the seventh day after surgery were observed in the patients. Results:After the implementation of early enteral nutrition in the observation group, the 1-and 3-year survival rates were 84.29% (59/70) and 61.43% (43/70) respectively, whereas in the control group, the survival rates were 64.29% (45/70) and 47.143% (33/70) respectively, with statistically significant differences between the two groups (P<0.05). At the first and seventh day after surgery, the serum albumin, hemoglobin, alanine aminotransferase, and aspartate aminotransferase levels were significantly better in the observation group than in the control group, with statistically significant differences between the two (P<0.05). Compared with the parameters in the observation group at the first day after surgery and those in the control groups at the eighth day after surgery, the levels of IgA , IgG, IgM and CD42+cells, NK cells, and B lymphocytes were significantly increased in the obser-vation group at the seventh day after surgery. The differences among them were statistically significant (P<0.05). Conclusion: Early postoperative enteral nutrition for the gastric cancer patients undergoing radical surgery can be effective in improving the nutrition level of the patients and in enhancing their long-term survival rate, Thus, the treatment has value in clinical application.

OBJECTIVE To study the risk factors related to the infection in the patients with the breast implant and soft tissue expander postoperatively,such as the time of drainage and retro-irrigation.METHODS Thirty consecutive patients who underwent breast implants and soft tissue expander involving at least two sites and set negative pressure drainage tube were studied.For each patient with drainages at two sites,one was retro-irrigated during the early stage postoperatively,the other was not.The samples were from the skin out of the drainage tube,the drainage tube out of skin and the end of drainage after 2,4,6 and 8 days of the operation and at the time of removing the tube.Total samples were tested for bacteriology.RESULTS Samples were divided into two groups: common groups and retro-irrigated group with negative pressure drainage.A total of samples from each group for bacterial test were 170.The postive rate was 2.94% and 1.76%,respectively(P=0.474).The positive rate of bacterial test was closely related to the time at all 3 different sampling sites(P

Objective: To investigate the expression of HOPX gene in cervical cancer tissues and blood serum as well as its effect on cervical cancer HeLa cells, and to analyze its correlation to tumor maker CEAand CA125. Methods: 50 pairs of cervical cancer tissues and para-cancerous tissues as well as the peripheral blood samples from patients with cervical cancer, who were treated at Tianjin Binhai People’s Hospital and Tianjin Wuqing People’s Hospital from June 2015 to December 2017, were collected for this study; in addition, 50 samples of blood serum from healthy people were used as control. Real-time quantitative PCR (qRT-PCR) and immumohistochemical staining (IHC) were used to detect mRNA and protein expressions of HOPX in tissue and serum samples, NCBI-GEO data base and TCGA data base were used to collect the information on HOPX gene and patients’prognosis, and the correlation between HOPX expression and patients’prognosis was analyzed. Vectors over-expressing HOPX or control vectors were transfected into HeLa cells; MTT assay and colony formation assay were used to examine the proliferation ability of HeLa cells, Tranwell assay was used to detect the migration and invasion of HeLa cells, and Western blotting was used to detect the expression of EMT-related proteins. Results: Both sample examination and data base information showed that the expression level of HOPX was down-regulated in tissue and serum samples of cervical cancer patients and was positively related with the survival of patients (r=0.736， P<0.05); while it’s expression was negatively related to the level of CEAand CA125 in cervical cancer tissues and serum (r=-0.678, P<0.05). HOPX over-expression inhibited cell proliferation, migration and invasion, promoted the expression of E-cadherin but inhibited the expression of Vimentin and ICAM1 (all P<0.05 or P<0.001). Conclusion: HOPX is low expressed in cervical cancer tissues and blood samples, and negatively correlated with CEA and CA125, but positively correlated with the survival of patients. Thus, combination of HOPX and CEA/CA125 may improve the early diagnosis rate of cervical cancer and provide a new strategy for precision treatment of cervical cancer in future.
