Objective To explore the role of beta-2 adrenergic receptor in the pathogenesis of infantile hemangioma.Methods In vitro cultured infantile hemangioma endothelial cells were divided into propranolol and isoproterenol groups.The propranolol groups were further classified into 5 groups to be treated with propranolol solutions at concentrations of 10,15,20 μg/ml,EGM-2 medium (blank control group 1),and EGM-2 medium containing 0.16% DMSO (DMSO group) respectively,while the isoproterenol groups were classified into 4 groups to be treated with isoproterenol solutions at concentrations of 5,10,20 μg/ml and EGM-2 medium (blank control group 2) respectively.After 24-and 48-hour treatment,enzyme-linked immunosorbent assay (ELISA) was performed to measure the expression of beta-2 adrenergic receptor in cell culture supernatants in the above groups.Results After 24-hour treatment,15-μg/ml and 20-μg/ml propranolol groups showed significantly decreased expression of beta-2 adrenergic receptor compared with blank control group 1 and DMSO group (all P < 0.05).After 48-hour treatment,all the propranolol groups showed significantly decreased expression of beta-2 adrenergic receptor compared with the blank control group 1 (all P < 0.05).However,the expression of beta-2 adrenergic receptor was significantly higher in the 10-and 20-μg/ml isoproterenol groups than in the blank control group 2 after 24-hour treatment (all P < 0.05),and higher in the 20-μg/ml isoproterenol group than in the blank control group 2 after 48-hour treatment (P < 0.05).Conclusion Propranolol can down-regulate the expression of beta-2 adrenergic receptor on the surface of vascular endothelial cells,while isoproterenol can up-regulate its expression.

Objective To explore the influence of structured lipid emulsion on inflammatory cell factors and immunologic function in gastrointestinal cancer patients after operation.Methods From July 2010 to February 2012,80 postoperative patients with gastrointestinal cancer were randomly divided into 2 groups with 40 cases each by stratified sampling method:structured lipid emulsion group (observation group),physical mixture of medium-chain/long-chain triglycerides group (control group).Both groups received isonitrogenous and isocaloric parenteral nutrition for 6 days after operation.The general conditions after operation were compared between two groups.Inflammatory cell factors and immunologic function were measured before operation,the 1st day and 7th day after operation.Results After 6 days parenteral nutrition,the vital sign data,blood routine,liver and renal function,blood fat etc was normal in two groups.There was no significant difference in the incidence of postoperative infection complication and hospitalization duration between observation group and control group [12.5%(5/40) vs.25.0%(10/40),[( 12.9 ± 0.7 d) vs.(13.1 ±0.9) d] (P >0.05).The serum levels of interleukin (IL)-1,IL-2,IL-6,tumor necrosis factor (TNF)-α on the 1st day after operation in two groups decreased,then gradually increasing.The serum levels of IL-2,IL-6,TNF- α on the 7th day after operation in observation group[(987 ± 203),(277 ± 107),( 197 ± 98) ng/L] were lower than those in control group [(1347 ± 195),(752 ± 187),(342 ± 106) ng/L](P<0.05 ).The serum levels of IgG,IgA,IgM,CD3+,CD4+ and CD8+ on the 1st day after operation in two groups decreased,then gradually increasing.The serum levels of IgG,CD3+,CD4+ were higher in observation group [( 14.2 ± 1.8 ) g/L,0.746 ± 0.111,0.580 ± 0.067] than those in control group [( 12.1 ± 2.8) g/L,0.606 ±0.101,0.404 ± 0.072] (P <0.05).Conclusion Structured lipid emulsion can reduce immunological suppression and inflammation in gastrointestinal cancer patients after operation,regulate the inflammatory cell factors producing and releasing,improve the immunologic function.

Objective To investigate the effect of ellagic acid on human epidermal melanocyte melanogenesis and melanin transfer, and the mechanism thereof. Methods The human melanocytes and and keratinocytes were co-cultured and purified. After passing the second generation, cells of 1∶10 ratio were inoculated into the small dish (3 cm × 3 cm). The changes of melanin content and tyrosinase activity in melanocytes were detected before and after intervention with ellagic acid (100, 10 and 1 mg/L) for 48 h. The melanin transfer in cultured cells was detected by flow cytometry method. The 10 nmol/L arbutin was used as the positive control. Results The tyrosinase activity was down-regulated by ellagic acid in a dose-dependent manner. The ellagic acid can reduce the melanin content except for the 1 mg/L of ellagic acid. The melanin transfer was also inhibited by ellagic acid in a dose-dependence manner. Conclusion Ellagic acid can be used for skin-whitening cosmetic and the depigmenting effect might be due to the down-regulation of melanogenesis and melanin transfer.

Objective To evaluate the effects of reserved jejunal feeding tube during postoperative chemotherapy of gastric cancer. Methods Forty-two patients with gastric cancer underwent radical gastrectomy and going to adjuvant chemotherapy,conventional placed jejunal feeding tube. All of the patients weredivided into group A and group B randomly by pathological staging and tumor site, group A reserved jejunal feeding tube and received enteral nutrition through the tube during chemotherapy, and group B non-reservedjejunal feeding tube and been given daily diet,compared nutrition and immune indicators of two groups beforeand after chemotherapy ,compared the rate of vomiting,and observed complications long-term reserved jejunal feeding tube. Results In post-chemotherapy,nutrition and immune indicators of group A were betterthan those of group B, the difference was statistically significant (P<0.05) ,the rate of vomiting in group Awas significantly lower than that of in group B (X2= 9.75, P<0.01 ), no serious complieations occurred forlong-term reserved jejunal feeding tube. Conclusions Reserved jejunal feeding tube and received enteralnutrition through the tube during postoperative chemotherapy of gastric cancer can significantly improve the nutritional and immune status. It is safe and reliable, worth promoting.

Objective To study prevalence of metabolic syndrome (MS) , it's components and hyperuricemia (HUA) among Kazakh people in Xinjiang Uighur autonomous region, China. Methods A cross-sectional survey was conducted among Kazakh people aged 35 years and over in seven prefectures of Xinjiang, including Urumqi, Kelamayi (Karamay) , Fukang, Tulufan (Turpan), Hetian (Hotan) , Aletai (Altay) and Yili during October 2007 to March 2010, with a four-stage cluster sampling, the total sample size were 4094. Through the methods of questionnaire survey, physical examination, biochemical examination and so on, to study prevalence of MS in HUA and it's components by blood biochemical examinations. Results A total of 3915 Kazakh adult people, equal number of men and women, were surveyed, with a response rate of 95. 63 percent. Overall prevalence of HUA was 3. 96 percent( 155/3915 ) , 6.02 percent for men and 2. 03 percent for women(114/1894 and 41/2021) , respectively, with statistically significant difference ( P < 0.05 ). Prevalence of MS was 39.47 percent in those with HUA and 22. 53 percent in those without HUA (45/114 and 401/1780), respectively (P < 0.01). Among women, prevalence of MS was 46. 34 percent in those with HUA and 16. 11 percent in those without HUA( 19/41 and 319/1980), respectively (P<0. 01). Prevalence of high blood pressure, hypertriglyceridemia, lower blood high-density lipoprotein cholesterol (HDL-C) and central obesity were 59.65 percent, 42.11 percent,32.46 percent, 7. 89 percent and 79. 82 percent in those with HUA, respectively, with prevalence of hyperglyceridemia and central obesity significantly higher than in those of non-HUA ( P < 0. 05 ). Among women, prevalence high blood pressure, hypertriglyceridemia, lower blood HDL-C and central obesity were 48.78 percent, 39.02 percent, 41.46 percent, 2.44 percent and 78.05 percent, respectively, in HUA group, with prevalence of hyperglyceridemia, lower blood HDL-cholesterol and central obesity significantly higher than in those of non-HUA ( P < 0. 05 ). Conclusions Prevalence of MS was higher in Kazakh people suffered with HUA than those without HUA, as well as prevalence of components of MS, suggesting that prevention and treatment for HUA is necessary, which can reduce MS and its components in the region.
