Objective:To study the expression and correlation of tumor-associated macrophages(TAM) and CCL5 in ganstric cancer.Methods:48 cases patients with completed clinical and pathological data of gastric cancer paraffin block specimens were select-ed.Cancer tissues and adjacent tissues were used as control,using SP immunohistochemical method to detect CD68 and CCL5 in gastric cancer tissues and adjacent tissues,and using the Spearman correlation statistics statistical methods for the correlation.Results:CD68 and CCL5 showed positive expression in gastric cancer tissue,significantly higher than those in the adjacent tissues(P<0.01),CD68 and CCL5 were related with gastric cancer invasion depth, lymph node metastasis, TNM stage and tumor differentiation ( P<0.001 ) . There was positive relation between the expression of CD68 and CCL5 in gastric cancer(P<0.01,r=0.759).Conclusion: CD68 and CCL5 played a driving role to the invasion and metastasis of gastric cancer occurrence,suggesting that the secretion CCL5 by TAM may promote the invasion and metastasis of gastric cancer.

Objective To investigate the prevalence of anxiety and depression in elderly patients with metabolic syndrome (MS) and its related factors.Methods A total of 672 subjects aged 60 or over undergoing health check-up in two Nanjing community health service centers from November 2015 to October 2016 were enrolled in the study.The basic information and the history of hyperlipidemia,hypertension and diabetes were collected by questionnaire survey;the results of physical examination and biochemical testing were documented.The prevalence of anxiety and depression were investigated by the Hospital Anxiety and Depression Scale (HADS).According to MS diagnostic criteria,the subjects were divided into MS group (n=181) and non-MS group (n=491).The HADS scores of two groups were compared and the influencing factors related to anxiety and depression were analyzed.Results The levels of systolic blood pressure (SBP),diastolic blood pressure (DBP),body mass index(BMI),levels of fasting blood glucose (FBG),triglyceride (TG),low density lipoprotein cholesterol (LDL-C) were higher and high density lipoprotein cholesterol (HDL-C) was lower in MS group than those in non-MS group (all P<0.05).The prevalence rates of anxiety and depression in MS group (30.9% and 34.8%) were significantly higher than those in non-MS group (20.2% vs.25.1%,χ2=8.655,6.288,P=0.003,0.012).Multivariate logistic regression analysis showed that obesity (BMI≥28 kg/m2),high FBG (≥7.0 mmol/L),hypertension [blood Pressure≥140/90 mmHg (1 mmHg=0.133 kPa)] were the independent risk factors for anxiety in MS patients (OR=3.987,2.827,2.375,respectively,all P<0.05);obesity (BMI≥28 kg/m2),high FBG(≥7.0 mmol/L),smoke,high TC (≥5.2 mmol/L),hypertension (≥140/90 mmHg) were the independent risk factors for depression in MS patients (OR=7.718,3.233,2.071,1.932,1.910,respectively,all P<0.05).Conclusion Elderly patients with metabolic syndrome are prone to anxiety and depression,and obesity,high FBG,hypertension and other factors are the risk factors for anxiety and depression.

Objective:To observe the changes of blood glucose,insulin and dipeptidyl peptidase-Ⅳ(DPP-Ⅳ/CD26)on type 2 diabetes mellitus in rabbits after HUCBSC( human umbilical cord blood stem cells) transplantation. Methods:18 rabbits were randomly divided into normal control group (6 rats,Group C) and diabetic model group (12 rats). After preparation model of type 2 diabetes,and 6 rats of them were treated with HUCBSC ( CD45+,CD34-) transplantation by ear vein transfusion ( Group A) ,and 6 rats were treated with PBS(Group B). All three groups of rabbits were fed for 4 weeks,and the blood glucose was monitored every day,and the level of blood insulin and DPP-IV/CD26 were measured every week. Results:The negative expression rate of CD34 in HUCBSC was 96. 5%. The positive expression rate of CD45 in HUCBSC was 100%. Compared with non transplantation group,the blood glucose and DPP-IV/CD26 in the umbilical cord blood stem cell transplantation group were gradually decreased,and insulin level was gradually increased, the difference was statistically significant (P<0. 01). Conclusion:HUCBSC were round or oval,with adherent growth,HUCBSC trans-plantation can significantly reduce blood glucose, increase insulin secretion, reduce the level of DPP-IV/CD26, the immunological phenotype of HUCBSC was CD45+,CD34-,thus providing a new theoretical basis for the clinical treatment of diabetes and its complica-tions.
