After mice given Ammoniun Glycyrrhizanate orally, the spleen weight, the number of leukocytes in peripheral circulation and carbon particle cleaning index increased significantly. Rat spleen lymphocytes exposed to 8 x10-7M and 8 x10-10M of Ammoniun Glycyrrhizanate produced levels of PGE that were 1 - 2 -fold greater than that of the control lymphocytes cultured in medium alone. We also found that the levels of PGE2 and cAMP in mice spleen increased significantly after P.O. Ammoninn Glycyrrhizanate, which we suggested might be the mechanisms of immane regulatory functions of Ammoniun Glycyr rhizanate.

The total aralosides extracted from Aralia elata (Miq) Seem. were studied in mice ( 50 mg/kg/d for 7 d ) to investigate the pharmacological mechanisms on the molecular level.The results showed that aralosides can obviously stimulate the production of PGE2、PGF2, and cAMP but reduce the cGMP level and nave no effect on histamine release.It is suggested that the changes in the level of cyclic nucleotide might be due to the alternations of PGs, which is now been suspected as the "Second Messenger" . These findings could explain in part the pharmacological activities of aralosides on the molecular level.

Objective To explore the relationship of the ADAM33 gene Q-1,T2 single nucleotide polymorphism (SNP) and suffering from chronic obstructive pulmonary disease (COPD) in Xinjiang Kazakh and Han population. Methods Peripheral blood samples to extract DNA, and the single nucleotide polymorphisms of Q-1 and T2 in ADAM33 gene were detected by SNaPshot SNP genotyping. Results Case group compared with the control group, frequencies of Q-1 locus genotypes and alleles were significant differences in Kazak (P<0.05). In patient group, there were significant differences in ADAM33 gene Q-1 locus genotypes FEV1% predicted, FEV1/FVC of clinical indicators lung function in Kazak, Han(P < 0.05). Kazak Q-1 locus AA genotype,Han GA genotype than GG genotype were significant difference.Compare Kazak AA genotype,Han GA genotype with GG genotype is more likely to cause COPD in Q-1 locus(P<0.05). In the comparison of the case and control group the two ethnic, there was no significant difference between the frequencies of T2 locus genotypes and the frequencies of Q-1,T2 the alleles (P > 0.05). There were no significant differences in T2 locus genotypes and clinical indicators of lung function FEV1% predicted and FEV1/FVC in patient group (P > 0.05). Conclusion The ADAM33 gene Q-1 locus may be related to the COPD susceptibility in Xinjiang Kazak, Han.

Objective To explore the effects of transcranial magnetic stimulation (TMS) on motor function in patients with Parkinson's disease (PD) using meta-analysis. Methods Eight comparative studies of the effects of TMS were meta-analyzed. Results The combined studies confirmed a significant difference before and after TMS treatment. Between the experimental and control groups the effect was also highly significant. Conclusion TMS may play an active role in the rehabilitation of motor function for patients with Parkinson's disease.

Objective To assess the diagnostic value of Logistic model in differentiating between malignant and benign ovarian lesions. Methods Thirty-five indexes of clinical and ultrasound data were recorded in 601 ovarian lesions confirmed by surgical pathology. The Logistic model was developed on a training set( n - 400) and tested on a test set( n = 201). Results Variable selection resulted in a set of 10 variables for the models: personal history of ovarian cancer, maximal diameter of the lesion, maximal diameter of the solid component, multilocular-solid tumor, solid tumor, ascites, flow within papillation, irregular walls, very strong intratumoral blood flow (i. e. color score 4) and acoustic shadows. Test set area under the receiver-operating characteristics curve was 0.963 with a sensitivity 93.9% and a specificity 93. 1 %. Conclusions Logistic model can accurately separate malignant from benign ovarian masses.

Objective To investigate the clinical effects of pedicled omentum covering the intestinal anastomotic stoma in preventing anastomotic fistula.Methods The clinical data of 133 patients with high risk of intestinal anastomotic stoma who were admitted to the Henan Tumor Hospital from May 2009 to May 2012 were retrospectively analyzed.All patients were divided into the improvement group (69 patients) and the control group (64 patients) according to whether the anastomotic stoma was covered by pedicled omentum.All the operations were done by the surgeons in the same group,and the intestinal reconstruction was done by the equipment produced by the same company.All the patients with intestinal tumors received radical resection.The clinical data of the patients in the 2 groups were reviewed and the therapeutic effects of the 2 approaches were compared.All data were analyzed using the chi-square test.Results Three (4.3％) patients had intestinal fistula in the improvement group,including 1 had small bowel anastomotic fistula,1 had small bowel and colonic anastomotic fistula,1 had colonic anastomotic fistula.Eight (12.5％) patients in the control group had intestinal anastomotic fistula,including 1 had duodenal anastomotic fistula,2 had small bowel anastomotic fistula,2 had small bowel and colonic anastomotic fistula,and 3 had colonic anastomotic fistula.There was a significant difference in the incidence of anastomotic fistula between the 2 groups (x2 =5.483,P ＜ 0.05).The highest body temperatures of the 3 patients in the improvement group were under 38.2 ℃,and the mean white blood cell count was 8.4 × 109/L;no peritonitis was detected; turbid drainage was observed in the peritoneal tube around the anastomotic stoma.The results of computed tomography showed local inflammation.The highest body temperatures of the 8 patients in the control group were above 38.5 ℃,and the mean white blood cell count was 14.4 × 109/L; obvious pressing pain and rebound tenderness were detected; intestinal contents were observed in the peritoneal drainage tube.The 3 patients in the improvement group were cured by symptomatic treatment.Of the 8 patients in the control group,7 received two-stage debridement,and 1 received jejunostomy and 3 received ileostomy.The condition of the 7 patients was recovered after operation,and reversion of the ileum at postoperative month 4.One patient died of multiple organs dysfunction syndrome and systemic inflammatory response syndrome.Conclusion Intestinal anastomotic stoma covered by pedicled omentum could effectively decrease the incidence of anastomotic fistula and alleviate systemic inflammatory response syndrome caused by anastomotic fistula.

Objective To explore the relations between the post pancreatoduodenectomy pancreatic anastomotic hemorrhage and the length of pancreatic duct endoprosthesis placed in the jejunum.Methods From August 2006 to August 2011,63 patients underwent pancreaticoduodenectomy with the adopted child method for digestive tract reconstruction,while pancreaticojejunostomy reconstruction was divided into A,B,C groups.There were 22 cases in A group,and patients underwent pancreaticojejunostomy with anastomosis of the pancreatic stump into the jejunum strapping method,the length of pancreatic duct endoprosthesis placed in the jejunum was 15 cm; there were 21 cases in B group,and patients received the same operation as patients in group A,but the length of pancreatic duct endoprosthesis placed in the jejunum was 5 cm; there were 20 cases in C group,and patients received pancreatic stump and jejunal mucosa anastomosis,the length of pancreatic duct endoprosthesis placed in the jejunum was 5 cm.Results In group A,two cases (9.1％) of pancreatic anastomotic hemorrhage occurred,and patients were cured by conservative treatment.In group B,eight cases (38.1％) of pancreatic anastomotic hemorrhage occurred,and two cases died of gastrointestinal bleeding; 3 cases received surgical operation to stop bleeding,and 3 patients were cured by conservative treatment.There was no anastomotic hemorrhage occurred in group C.The bleeding times of group A and group B were about 15 days after surgery,the difference of incidence of anastomotic bleeding between the two groups was statistically significant (x2 =9.428,P =0.009).Conclusions Post pancreaticojejunostomy anastomotic hemorrhage is associated with short length of pancreatic duct endoprosthesis placed in the jejunum.
