Cultured human embryonal thymus graft was performed on 80 patients with allergic rhinitis to observe the immune function of the patients and the treatment efficiency. The thymus from the fetus of intermediate abortion was cultured for 7 to 10 days. The T cell subsets and serum antigen special IgE(sas IgE) level of the patients were determined before and after the thymus transplantation. The gross treatment efficiency is up to 92.4% among the trial patients after graft for 3 years and CD8 positive cells were increased with a significantly statistical difference (P＜0.01), and sas IgE level was much lower than before thymus transplantation (P＜0.01). It was concluded that the thymus transplantation might regulate the immune function of the patients with allergic rhinitis, including increases in the number and the function of Ts cells, and a decrease of IgE level.

Objective:To clarify the relationship between epidermal growth factor receptor (EGFR) mutations and the clinicopathologic features of primary lung adenocarcinomas in Xinjiang.Methods:The mutations of EGFR gene at exons 18 -21 in 59 cases (including 15 cases of Uighur and 44 cases of Han) of lung adenocarcinoma tissues,which were obtained from surgical resection,were detected by amplifica-tion refractory mutation system (ARMS)method.And the relationships among mutations,race and clini-copathologic features were analyzed.Results:The frequencies of EGFR mutations in lung adenocarcinoma were 20% for Uighur,which was lower than that in Han (54.5%),P <0.05.The deletion mutations at exon 19 were seen in 2 of 15 Uighur cases and 9 of 44 Han cases.EGFR mutations were present,inclu-ding exon 21 L858R in one Uighur case and 12 Han cases,exon 18 G719X in two of 44 cases of Han, exon 21 L861Q in one of them.On histological type,the frequencies of EGFR mutation in alveolar pre-dominant adenocarcinoma was 71% (22 /31),which was higher than both that in solid predominant and mucinous carcinoma (6.7%,20% respectively).According to statistic analysis,EGFR mutations were without correlation with the patient’s gender,age,location,gross type,smoking status and lymph node metastasis(P >0.05).EGFR mutation was more frequent in well-differentiated cancer,mainly in acinar carcinoma,while poorly differentiated adenocarcinoma and mucous adenocarcinoma were lower.Conclu-sion:There was a difference of EGFR mutation in primary lung adenocarcinoma between Uighur and Han in Xinjiang,perhaps reflecting ethnic genetic variation,which is worth further analyzing.EGFR mutation was commonly detected in well or middle differentiated adenocarcinoma,mainly in acinar carcinoma.

Objective To explore the clinical efficacy of knee osteoarthritis treated by abdominal acupuncture combined with sodium hyaluronate injected in intraarticular.Methods 120 patients with knee osteoarthritis were randomly divided into observation group and control group,60 patients in each group.The observation group was treated by abdominal acupuncture combined with sodium hyaluronate injected in intraarticular.The control group was treated with intraarticular injection of sodium hyaluronate alone.Results After a follow up of 6 months, the total effective rate of the treatment group was 95.00%,which was higher than 78.33% of the control group, the difference was statistically significant (x2=7.21,P<0.01).Conclusion Abdominal acupuncture combined with intraarticular injection of sodium hyaluronate is a good way to treat middle and old age patients with knee osteoarthritis.

Objective The kinds and activities of proteolytic enzymes of tongue,esophagus,craw,muscular stomach,glandular stomach,duodenum,large intestine,pancreas,liver in digestive system of Buteo buteo were studied to provide basic information for taxonomy and evolvement study of wild birds. Methods The experiment was carried out at 4℃ by using gelatine polyacrylamide gel electrophoresis(G-PAGE) ameliorated by Xu Cunshuan. Results 1.At least 26 kinds of proteolytic enzymes were found in digestive system of Buteo buteo.2.The kinds and activities of proteolytic enzymes in the digestive system of Buteo buteo were affected by pH.The activities of proteolytic enzymes was the weakest in the acid environment and the strongest in the alkaline environment,showing that the activity of the alkaline proteolytic enzymes were stronger than that of the neutral proteolytic enzymes,and that of the acid proteolytic enzymes were weakest.3.Duodenum and pancreas had more kinds and stronger activities of proteolytic enzymes than those in tongue,esophagus and craw in any pH value condition.4.The proteolytic enzymes with 75 and 70?kD molecular weight existed in every organ of digestive system except pancreas and liver in any pH condition.Conclusion The similarity of the kinds and the activities of proteolytic enzymes exist in the organs with similar structure and similar functions. The proteolytic enzyme of 75 and 70?kD molecular weight,whose pH-dependent activity is not obvious,exists widely in digestive system of Buteo buteo.The activity of proteolytic enzyme with 198?kD molecular weight is found in every organ of digestive system under pH 8.5 condition.

Objective The kinds and activities of proteolytic enzymes of organs in the digestive system of Grus grus were studied to provide basic information for the taxonomy and evolvement study of wild birds. Methods The experiment was carried out at 4℃ by using gelatine polyacrylamide gel electrophoresis(G-PAGE) ameliorat. Results 1.Altogether 26 kinds of proteolytic enzymes were found in the digestive system of Grus grus in all pH value conditions.2.The kinds and activities of proteolytic enzymes in the digestive system of Grus grus were affected by pH.The activities of proteolytic enzymes were weakest in the acid environment and strongest in the neutral environment,which shows that the activities of the neutral proteolytic enzymes were stronger than those of the alkaline proteolytic enzymes,and those of the acid proteolytic enzymes were weakest.3.The kinds and activities of proteolytic enzymes of the same organ varied tremendously in different pH value conditions.The proteolytic enzymes of different organs had different optimal pH values.4.Proteolytic enzymes with 19?kD molecular weight existed in every organ of the digestive system except glandular stomach in all pH conditions.Proteolytic enzyme with 66 and 22?kD molecular weight was found in every organ of the digestive system in the neutral environment.Conclusion The optimal pH value of proteolytic enzymes in the digestive system of Grus grus is 7.0.The distribution,activity and pH-dependency of proteolytic enzymes of 66?kD,22?kD,19?kD molecular weight are the important characteristic of proteolytic enzymes in the digestive system of Grus grus.

OBJECTIVETo assess whether the plasminogen activator inhibitor-1 (PAI-1) gene 4G/5G polymorphism is associated with coronary heart disease (CHD) in Chinese patients.

METHODSPAI-1 gene 4G /5G polymorphism was analyzed in normal group (121 individuals) and CHD group (126 cases) by a combination of polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).

RESULTSThe 4G allele and 4G/4G genotype frequencies of PAI-1 gene (0.60 and 0.397) for CHD patients were higher than those (0.48 and 0.190) for healthy controls(chi-square=7.63 P<0.01; chi-square=12.67, P<0.01). The odds ratios(OR) for CHD in subjects with the 5G/5G (and 4G/5G) genotypes were 2.54 (95% CI 1.22-5.27, P<0.05) and 1.28(95% CI 1.45-2.38, P>0.05), respectively.

CONCLUSIONThese results suggest that the PAI-1 4G/4G genotype is associated with an increased risk for CHD in Chinese patients. The subjects with the 4G/4G genotype had a higher prevalence of CHD, compared to those with the 5G/5G PAI-1 genotype.
