Pancreatic stone protein (PSP) is the product of exocrine pancreas mainly synthesized and secreted by the pancreas acinar cells, a small amount secreted by gastrointestinal cells. PSP is one of stress protein family members secreted in the pancreas. PSP increased in acute and chronic pancreatitis, diabetes, inlfammatory bowel disease and gastrointestinal tumors. In recent years, some studies showed that PSP has potential clinical value in pancreatic injury and sepsis. In this article, we reviewed the progress of pancreatic stone protein in pancreatic injury and sepsis.

Objective To investigate the influence of rosuvastatin on inflammatory factors and immune func-tion in chronic obstructive pulmonary disease(COPD)with pulmonary heart disease.Methods 80 COPD patients with pulmonary heart disease were randomly divided into two groups,40 cases in each group.The control group was treated with conventional medicine comprehensive treatment,the observation group was given rosuvastatin based on the control group.The inflammatory cytokines (TNF -α,IL -1 and hs -CRP)changes,immunoglobulin IgM,IgG and IgA changes situation,and heart,lung function changes related indicators were compared between the two groups before and after the treatment.Results After treatment,the TNF -α,IL -1 and hs CRP levels of the observation group were significantly lower than those before treatment(t =145.5,35.35,57.5,all P <0.05)and those of the control group(t =160.75,11.45,32.99,all P <0.05).After treatment,the IgM,IgG and IgA levels of the observa-tion group were significantly lower than those before treatment (t =4.89 of 18.29,3.42,all P <0.05)and those of the control group (t =2.55 9.67,2.342,all P <0.05 ).After treatment,the FEV1 ,FEV1 /FVC and LVEF of the observation group were significantly higher than those before treatment(t =40.44 33.64,33.79,all P <0.05),while the PAP level was significantly lower than that before treatment (t =24.12,P <0.05),and the FEV1 ,FEV1 /FVC and LVEF of the observation group were significantly higher than those of the control group after treatment(t =16.30, 15.82,18.72,all P <0.05),while the PAP level was significantly lower than that of the control group after treatment (t =13.43,P <0.05).Conclusion Combined rosuvastatin therapy for COPD patients with pulmonary heart disease can effectively reduce body inflammatory response,improve immune function and myocardial contractility,so it can promote functional recovery of heart and lung in patients.

Aim To investigate the effects of pumpkin polysaccharide(PP) on Fas、Fas-L、Bcl-2 and Bax expression in the pancreas of diabetic rats.Methods Rats were injected intraperitoneally(ip) with streptozocin(STZ) 60 mg?kg-1 to induce diabetic model.The diabetic rats were given PP 150 mg?kg-1,300 mg?kg-1,600 mg?kg-1.The blood sample were taken after three weeks.Blood glucose was measured by glucose oxidase method;The expression of the Fas and Fas-L have been determined by using immunohistochemistry(S-P method);The expression of Bax mRNA and Bcl-2 mRNA were checked up by Reverse transcription PCR(RT-PCR).Results PP could decrease the level of blood glucose in streptozotocin-induced diabetic rats;After three weeks,The expressions of the Fas and FasL in ? cell of streptozotocin-induced diabetic rats were obviously lower;The expression of Bax mRNA was obviously down-regulated,the expression of Bcl-2 mRNA was obviously up-regulated,and the ratio of Bcl-2/Bax was advanced after the diabetic rats were given PP.Conclusions PP could decrease the level of blood glucose of the diabetic rats.The mechanism was related to decreasing the expressions of the Fas and FasL and regulating the expressions of Bcl-2 and Bax in the pancreas of diabetic rats.

Objective:This study aimed to investigate the relationship between estrogen receptor (ER) and Bcl-2 in cervical can-cer and precancerous lesions. Methods:ER and Bcl-2 were evaluated by immunohistochemistry in 20 non-tumor tissues, 30 low-grade cervical intraepithelial neoplasias, 70 high-grade cervical intraepithelial neoplasias, and 80 cervical cancers. Results:The positive rate of ER was 75%in non-tumor tissues;this rate decreased with disease severity (χ2=24.266, P<0.01). The overexpression of ER protein was remarkably lower in cervical intraepithelial neoplasias (CIN) Ⅱ-Ⅲ and carcinomas than in non-tumorous cervices. Differences were not significant between CINⅠand non-tumorous cervices (χ2=0.751, P=0.386). Furthermore, ER expression was not correlated with histological type and tumor grade. The positive rate of Bcl-2 was 75.38%in squamous cell carcinoma. This rate increased with dis-ease severity (χ2=27.715, P<0.01). The Bcl-2 protein overexpression was remarkably higher in CINⅠ, CINⅡ-Ⅲ, and carcinomas than in non-tumorous cervices. Bcl-2 expression was also not correlated with histological type (P=0.500);by comparison, Bcl-2 expression was correlated with tumor pathological grade (χ2=4.862, P=0.027). The co-expression of ER and Bcl-2 was 38.57%and 15.38%in CINⅡ-Ⅲand squamous cell carcinoma, respectively;the differences between these two values were significant (χ2=9.108, P=0.003). A cor-relation between ER and Bcl-2 was observed in CINⅡ-Ⅲ(r=0.506, P<0.01);no correlation was observed between other groups. Con-clusion: ER expression was inversely correlated with Bcl-2 in cervical cancer progression. The co-expression of these markers may have an important function in the course of high-grade cervical intraepithelial neoplasia.

Objective To explore the relationship between quality life and TCM constitutions of elderly patients with hypertension in a community in Shanghai; To provide the basis for the suitable and feasible community elderly hypertension management method. Methods Through multistage stratified sampling method, 808 elderly patients with hypertension in the community were investigated for their life quality and TCM constitutions on the basis of inform consent and voluntary participation. The life quality and TCM constitution characteristics as well as the relationship were analyzed by applying the statistic analysis software. Results Among the investigated elderly patients with hypertension in the community, 97.28% cases’ overall life quality was above the middle level and 91.46% cases’ self-evaluated health and quality of life scores were above the middle level. 54.70% cases were gentleness type, and the biased constitution was dominated by qi deficiency, yang asthenia, yin asthenia and phlegmatic hygrosis. The relationship between life quality and TCM constitutions may be existent. If TCM constitutions tended to be gentleness type, the physical score and the psychological score would be higher, which leaded to better quality of life. Conclusion TCM constitution characteristics are associated with quality life of elderly hypertension patients in the community. Intervention targeted on the results of TCM constitution identification would be better to prevent and control hypertension and improve health level and quality of life.

Objective To study the role of CXC chemokine receptor 5 (CXCR5) in the pathogenesis of bullous pemphigoid (BP) by detecting the expression of CXCR5 on follicular helper T (Tfh) cells in skin lesions of BP.Methods An immunohistochemical procedure was used to detect CXCR5 expression in biopsy specimens from skin lesions of 16 patients with BP and normal skin of 10 healthy individuals.Results CXCR5 was mainly expressed in the cytoplasm and membrane of Tfh cells in the basal cell layer of normal skin as well as in both basal cell layer and prickle cell layer of BP lesions.The number of CXCR5-positive ceils per high power field (× 400) was 11.16 ± 4.47 in normal skin specimens,significantly lower than that in lesional skin specimens (35.70 ± 12.20,t =6.07,P ＜ 0.01).Conclusion CXCR5 may be involved in the pathogenesis of BP.
