Objective To evaluate the clinical application of HLA matching in highly sensitized recipients of renal allografts.Methods Recipient's panel reactive antibody (PRA) was detected by using ELISA test with Lambda antigen tray (LAT).Donor and recipient HLA classⅠtyping was performed with special monoclonal tray,and HLA classⅡgene typing with micro-sequence specific primers (Micro-SSP).Results There were 104 recipients with anti-HLA class-ⅠIgG antibody,76 with anti-HLA class-ⅡIgG antibody,and 44 with both anti-HLA class-1 and anti HLA class-ⅡIgG antibody respectively in 136 sensitized recipients.HLA class-ⅠIgG antibody positive rate was 11%-97 %,with an average of 49.6%?23.8%;The common public epitopes antibody was not found in each recipient of 13 cases with PRA＜20%,but was found in I2 recipients in 44 cases with PRA be- tween 20%-50%,and 39 recipients in 47 cases with PRA＞50%.HLA class-ⅡIgG antibody posi- tive rate was 17%-100%,with an average of 28.2%?63.8%.The number of cases of 0,1,2,3, 4 MM was 7 (5.1%),26 (19.1%),47 (34.6%),39 (28.7%) and 17 (12.5%) respectively by the standard of conventional HLA antigen matching;however the number of the recipients with 0,1, 2,3 MM was 31 (22.8%),53 (39.0%),36 (26.5%) and 16 (11.7%) respectively according to the rule of HLA CREGs matching and none with 4 MM.Rates of acute rejection in sensitized recipi- ents with 2MM and 3MM HLA-CREGs were 25.0% and 37.5% respectively and were significantly higher than those with 0MM (P＜0.05,＜0.05 respectively).Kidney year-survival was decreased when the number of MM of HLA CREGs matching increased.Conclusion The HLA CREGs matching can improve the ratio of well-matched significantly.Good HLA matching can reduce the incidence of acute rejection in sensitized recipients and increase the survival rate of grafts.

AIM:To investigate the effects of ?v?6 integrin-mediated cell adhesion on 5-fluorouracil (5-FU) induced apoptosis in colon carcinoma cell lines.METHODS: The expression of the ?v?6 integrin in colon carcinoma cell lines HT-29 and WiDr cells was analyzed by flow cytometry. The apoptosis induced by 5-FU and the effects of ?v?6 integrin-mediated cell adhesion on 5-FU induced cell apoptosis were measured by enzyme-linked immunosorbent assay (ELISA) method and acridine orange-ethidium bromide (AO-EB) double fluorescent dye staining.RESULTS: Both the colon carcinoma cell lines HT-29 and WiDr cells expressed the ?v?6 integrin. The percentages of HT-29 and WiDr cells expression were 80.82% and 82.96%. 5-FU induced the apoptosis of colon carcinoma cell lines HT-29 and WiDr. The result of ELISA method displayed that enrichment factor (EF) of HT-29 and WiDr cells planted on fibronectin (FN)-ligand of ?v?6 integrin was lower significantly than the EF of HT-29 and WiDr cells planted on non-integrin ligand polylisin (1.11?0.04 vs 3.68?0.03, 1.09?0.02 vs 3.72?0.02, P

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

Objective To determine the genetic diversity of germplasm resource in cultivated and wild Cistanche deserticola. Methods Fifty-eight samples from three populations of cultivated and wild C. deserticola were analyzed by amplified fragment length polymorphism (AFLP) DNA markers, and the gene- tic diversity was evaluated by PopGen32. Results The average percentage of polymorphic loci (PPL) of cultivated C. deserticola is 79.16%. The PPL of wild population is 89.53%. Average Neis gene diversity index (He) from four populations was 0.193 8, Shannons genetic diversity index (I) was 0.300 4, and genetic differentiation index (Gst) was 0.097 9. Conclusion The diversities of cultivated and wild C. deserticola are both higher and theres no differentiation between them. It shows that genetic diversity of inner-species is higher, which is not the reason for endangerment. Therefore, wild nursery and artificial cultivating are the best measures for the conservation and sustainable utilization in C.deserticola.

Objective Explore reflux esophagitis age,symptoms,and the relationship between the degree of esophageal damage.Methods Summing up 198 cases of young and middle-aged patients and 104 cases of elderly pa-tients with the symptom score and Endoscopic mucosal injurs classification.Results Under the old group gastroscopy serious esophagitis more than the young group,old age group was 49.97%,25.25%for the young group,but the clini-cal symptoms of heart burn not obvious.Conclusion Reflux esophagitis damaged esophagus increased with age in-crease,but clinical heartburn symptoms do not necessarily obvious,it should attach importance to the brink throat dis-comfort,and other symptoms.

Objective To investigate the application effect of Kangfuxin Liquid on pain relief saliva SigA and IgG levels in patients with oral ulcer.Methods A total of 98 patients with oral ulcer treated in our hospital from January 2013 to July 2015 were randomly divided into two groups,with 49 cases in each group.The observation group was treated with Kangfuxin oral liquid,the control group was treated with stomatitis spray.The treatment effect, relieve pain, ulcer healing time and saliva SIgA, IgG levels in the two groups were observed,and whether the record of concurrent side effects.Results The effective rate of the treatment group was 89.79% higher than the control group 65.30%(P<0.05).Compared with before treatment, the observation group after treatment, the level of saliva SigA increased, IgG level decreased(P<0.05), the control group after treatment of saliva SIgA, IgG level of improvement is greater than that of the control group, the difference was statistically significant(P<0.05).The pain relief and healing time of the observation group were significantly lower than the control group(P<0.05).Conclusion The clinical effect of Kangfuxin liquid in treatment of oral ulcer in patients with significant clinical effect,reduce local ulcer pain, promote ulcer necrotic cell shedding and granulation tissue of newborn,increase the SIgA, IgG content, strengthen the local immunity response, promote oral ulcer healing, worthy of promotion.

Aim To study the immunomodulatory activity of total flavonoids of Litsea Coreana Leveille (LCTF) on cyclophosphamide(CY)-induced immunosuppressive mice. Methods CY (50 mg?kg-1) was administered by intraperitoneal(ip)injection for 2 consecutive days to induce immunosuppressive model. Carbon clearance, quantitative hemolysis and DNFB-induced delayed-type hypersensitivity(DTH) were applied to assay effects of LCTF on nonspecific immunity, humoral immunity and cellular immunity. Results In carbon clearance test, the clearance index (K) and values of phagocytic index (?) were elevated by LCTF (200 and 400 mg?kg-1), indicating the phagocytosis of macrophages was enhanced in immunosuppressive mice.In quantitative hemolysis, productions of IgM and IgG in serum and hemolysin in splenocytes were enhanced in immunosuppressive mice by LCTF (100 and 200 mg?kg-1). LCTF (200 and 400 mg?kg-1) obviously increased DTH reactivity in immunosuppressive mice. LCTF not only increased percentages of T cells expressing CD4+ and CD8+,but also enhanced the ratio of the two subset of T lymphocyte,and LCTF (200 and 400 mg?kg-1) could also improve IL-2 production of spleen lymphocytes. Conclusion LCTF showed significant immunomodulatory property on immunosuppressive mice through specific and nonspecific immunity.
