Objective To investigate the association of gene polymorphism of cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) with ulcerative colitis (UC) in Chinese patients. Methods The A+49G transition polymorphism at position 49 (exon 1) and C-318T transition polymorphism at position -318 in promoter of the CTLA-4 gene were determined by polymerase chain reaction with sequence specific primers (PCR-SSP) method in 82 Chinese patients with UC and 204 healthy controls of Han nationality. Results No significant differences in the distribution of genotype and allele frequencies were observed between CTLA-4 C-318T and A+49G gene polymorphisms in UC patients and normal controls. How- ever , comparing with healthy subjects,the frequency of haplotype 2,3 (C -318 -G 49 /T -318 -A 49 ) in UC patients was significantly reduced (26% vs 41%, P

OBJECTIVE: To investigate the relationship between visceral syndrome differentiation in traditional Chinese medicine (TCM) and the changes of nutrition status or blood gas analysis in patients with chronic obstructive pulmonary disease (COPD). METHODS: Sixty patients with COPD in stable phase were divided into dysfunction of lung (DL, n=20) group, dysfunction of lung and spleen (DLS, n=16) group and dysfunction of lung, spleen and kidney (DLSK, n=24) group according to syndrome differentiation of TCM. Moreover, the basic electric rhythm, percentage of bradygastria in electrogastrogram (EGG), ratio of actual body weight (ABW) to ideal body weight (IBW) and serum albumin level were determined to evaluate the nutrition status of the patients with COPD. Blood gas analysis was made too. RESULTS: The basic electric rhythm values in the DL, DLS and DLSK groups were (56.20+/-13.24)%, (47.38+/-10.24)% and (41.35+/-10.01)%, respectively. Compared with the DL group, the basic electric rhythm values in the DLS and DLSK groups decreased obviously (P<0.05). The percentages of bradygastria in the DL, DLS and DLSK groups were (45.18+/-18.13)%, (46.31+/-15.83)% and (49.90+/-17.54)%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of ABW/IBW<90% in the DL, DLS and DLSK groups were 50%, 75% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of serum albumin less than 35 g/L were 20%, 37.5% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). PO2 in the DLS group [(63.56+/-15.06) mmHg] and DLSK group [(63.17+/-19.05) mmHg] were decreased as compared with the DL group [(78.15+/-16.63) mmHg] (P<0.05). PCO2 in the DL, DLS and DLSK groups were (42.25+/-12.46) mmHg, (48.60+/-17.60) mmHg and (49.97+/-13.43) mmHg respectively, and there were no differences among the three groups (P>0.05). CONCLUSION: Several dysfunction organs described in TCM were involved in COPD followed by the increased severity, hypoxemia and PCO2. Dysfunction of gastrointestinal tract and malnourishment took place accordingly.

Objective To discuss the characteristics of multiple blood supplies and the significance of multiple intra-arterial embolization in massive hemoptysis. Methods Forty-four patients with massive hemoptysis underwent digital subtraction angiography (DSA) and intra-arterial embolization after ineffective medical treatment. The characteristics of blood supply of lesions,the methods of intra-arterial embolization and the clinic efficacy were retrospectively analyzed. Results All the patients, one artery was embolized in 9 patients,2 arteries were embolized in 18,3 in 14 and 4 in 3. The hemoptysis decreased or ceased immediately after intra-arterial embolization in 43 patients and recurrence within lweek in 2,which were controlled with additional emblization. 1 patient died in surgery. Conclusion The lesions of massive hemoptysis had complicated blood supplies,and multiple intra-arterial embolization was very important.

Objective To observe the expression of leukocyte-function-associated antigen-1(LFA-1)immunoreaction in children with febrile seizures(FS),and explore the neuroimmunomodulation mechanisms in the pathogenesis of FS.Methods Adopting flow cytometry(FCM),the levels of LFA-1 contained in blood serum and peripheral blood mononuclear cells(PBMC)of 60 cases [simple FS(SFS)30 cases;complex FS(CFS)30 cases] with febrile convulsion were analyzed,and compared with those in a normal group(30 cases).Out of 60 children with FS group,the LFA-1 mRNA in 20 cases with SFS and 20 cases with CFS was analyzed,and LFA-1 mRNA in19 health children taken out from control group(30 cases)was analyzed.The real-time PCR was used to detect the expression of PBMC LFA-1 mRNA.Results The expression of LFA-1 in the surface of PBMC of the 3 groups,the highest LFA-1 level was in the SFS group(50.89?21.36),the lowest LFA-1 level was in the CFS group(34.35?11.45),and control group was(41.39?16.30).Significant differences were found in 3 groups(Pa

Objective: To construct subtracted cDNA libraries of stomach tumors and normal stomach tissue using suppression subtractive hybridization(SSH).Methods: cDNA Library subtraction was performed using the protocol described in the Clontech PCR-Select cDNA Subtraction Kit. cDNA was synthesized from 2 μg of poly A+RNA from the tumor and normal tissues using AMV reverse transcriptase. The tester and driver cDNAs were digested with RsaⅠ, a four-base-cutting restriction enzyme that yields blunt ends. The tester cDNA was then subdivided into two portions, and each was ligated with different cDNA adaptor. Two hybridizations were performed. In the first, an excess of driver was added to each sample of tester. Hybridization kinetics led to equalization and enrichment of differentially expressed sequences. During the second hybridization, the two primary hybridization samples were mixed together without denaturing and thus the templates were generated from differentially expressed sequences for PCR amplification. Using suppression PCR, only differentially expressed sequences were amplified exponentially and after second PCR amplification the background was reduced and differentially expressed sequences were further enriched. The cDNAs were then directly inserted into a T/A cloning vector to generate a stomach tumor-specific subtracted cDNA library. Results: The amplified library contained 800 positive clones. Plasmid inserts were PCR amplified and showed 250－700 bp inserts. Conclusions: The successfully constructed subtracted cDNA library of gastrocarcinoma and normal tissue enables us to compare two populations of mRNA and obtain clones of genes that expressed in one population but not in the other.The characterization of these genes will allow them to be exploited for their diagnostic and therapeutic potentials.
