Objective:To determine the di-allelic polymorphisms of TNF gene and their association with Helicobacter Pylori(H.pylori) infection and gastroduodenal diseases in Chinese population with Han nationality.Methods:Two hundreds and ten patients with gastroduodenal diseases(73 chronic gastritis,78 duodenal ulcer and 59 noncardia gastric cancer) and 264 healthy controls were genotyped by the PCR-RFLP method for TNF-? 308,lymphotoxin-?(LT-?) Nco Ⅰ and AspH Ⅰ gene polymorphisms.H.pylori infection status was determined by a validated serological test.Results:H.pylori infection was detected in 90.5% of 210 patients and 62.1% of 264 healthy controls(P

Objective To investigate the effect of heme oxygenase-1 ( HO-1) on brain edema in a rat model of asphyxial cardiac arrest and resuscitation. Methods Forty male SD rats weighing 250-300 g were randomly divided into 4 groups ( n = 10 each) : group I sham operation; group II cardiac arrest (CA); group Ⅰ Hemin (HO-1 inducer) and group IV SnPP (HO-1 inhibitor). Asphyxial cardiac arrest and resuscitation were performed in CA, Hemin and SnPP groups (group Ⅰ ,Ⅲ, Ⅳ) . Hemin and SnPP groups received hemin 15 mg/kg intraperitoneally (IP) at 12 h before CA and SnPP K 30 μmol/kg IP at 1 h before CA respectively. The animals were sacrificed at 1 and 6 h after recovery of spontaneous circulation (ROSC) . The water content of the cortex, hippocampus and brain stem and the expression of HO-1 and aquaporin-4 (AQP4) mRNA in cortex and hippocampus ( by RT-PCR) were determined. Results Water content of cortex and hippocampus was significantly higher at 1 h after ROSC in CA and SnPP groups than in sham operation group and was significantly lower in Hemin group than in CA group. There was no significant difference in water content of brain stem at 1 and 6 h after ROSC among all 4 groups. The expression of AQP4 mRNA was significantly higher in cortex and hippocampus at 1 h after ROSC in CA and SnPP groups than in sham operation group and was significantly lower in Hemin group than in CA group.Conclusion HO-1 can reduce brain water content at early stage after cardiac arrest and resuscitation by regulating the expression of AQP4.

Objective To observe the curative effects of Ginkgo dipyridolum injection in the treatment of acute cerebral infarction and its influence on blood rheology and fibrinogen content.Methods 96 patients with acute cerebral infarction were randomly divided into two groups.39 patients in Ginkgo dipyridolum group were treated with 20 ml Ginkgo dipyridolum injection plus 500 ml saline intravenously,once a day.57 patients in control group were treated with Xuesaitong injection 10 ml plus 500 ml saline intravenously,once a day.All treatment lasted for 14 days.The score of neurological deficit was evaluated to assess the clinical efficiency,the changes of indexes of blood rheology,fibrinogen content and skull CT in the two groups were observed before and after treatment.Results Total effective rate(94.9%)in the Ginkgo dipyridolum group was signifcantly higher than that in the control group(78.9%)(P

Objective To study the distribution of IL-10 and TNF gene polymorphisms in patients with gastroduodenal diseases in Hubei Han ethnic and their association with Helicobacter pylori (Hp) infection. Methods Six hundred and five patients with gastroduedenal diseases (196 chronic gastritis, 189 gastroduodenal ulcer and 220 gastric cancer) as well as 624 healthy controls were genotyped with PCR-RFLP method for IL-10-1082,-819,-592 and TNFα-308, lymphotoxin-α (LTα) Nco Ⅰ and AspH Ⅰ gene polymorphisms. Hp infection status was determined with ELLS& Results (1) There was significant difference of IL-10-1082 AG + GG genotype among the gastric cancer group with the non-malignant gastric diseases groups and healthy control group (P <0. 05). There was no significant difference of IL-10-592 and -819 gene polymorphisms among gastric cancer patients,non-malignant gastric disease patients and healthy controls (P>0. 05). The genotype frequencies of IL-10-819 were the same as those of IL-10-592. (2) Frequency of IL-10-1082 AG + GG genotype in gastric cancer patients with positive Hp was significantly higher than that in the other three groups (P < 0. 05). (3) Frequency of LTα Nco I AG genotype in gastric cancer patients with Hp infection was signiilcandy higher than that in Hp positive healthy controls (P < 0. 05). There were no other associations between TNFα-308, LTα Nco Ⅰ and AspH Ⅰ gene polymorphisms and Hp infection in gastroduodenal diseases. Conclusions (1) Allele AG + GG of IL-10-1082 was associated with gastric cancer in Han nationality of Hubei province. (2) IL-10-1082 AG + GG,LTct Nco ⅠAG heterozygous genotype may be associated with Hp infection in patients with gastric cancer in Han nationality of Hubei province.

By use of color Doppler ultrasonography (ATLHDI 5000,made in USA),a prospective study was made in 362 aged (greater than or equal to 60 years) patients (252 males and 110 females) for a period of 3 years.There were 176 patients (48.2%,130 males and 46 females) had degenerative vavular disease (DVD).The incidence increased with the aging of the population.There were no evident differences between males and females.Degenerative aortic valvular deformation was most frequently found (in 171 cases),followed by mitral (in 24 cases).The complications were hypertension,diabetes and coronary heart disease.It suggests that the DVD in the elderly mainly occurs in aortic valves,then in mitral value.Its incidence increases with aging.Complications such as hypertension,diabetes and coronary heart disease are important risk factors of DVD.

Objective To investigate an association between Toll-like receptor(TLR)4 Asp299Gly or CD14 C-260T polymorphisms and colorectal cancer in Chinese patients.Methods By a method of polymerase chain reaction-based restriction fragment length polymorphism(PCR-RFLP), TLR4 Asp299Gly and CD14 C-260T polymorphisms in unrelated 110 patients with colorectal cancer and 160 healthy controls in Chinese Han race population were genotyped.Results Significant differences of CD14 genotypes were found between healthy controls and the patients with colorectal cancer.The fre- quency of the CC genotype in healthy controls was extremely lower than that in the group of colorectal cancer(15.6% vs.31.8%,P=0.0027,OR=0.3968,95%CI:0.2209-0.7129)while the frequency of the CT genotype in healthy controls was significantly higher than that in the group of colorectal cancer (48.1% vs.30.9%,P=0.0056,OR=2.074,95%CI:1.246-3.452).No TLR4 Asp299Gly mutant genotype was detected in any patients and healthy controls in Chinese Han population.Conclusion The polymorphism of CD14 C-260T but not TLR4 Asp299Gly is associated with colorectal cancer in Chinese patients.
