In the same pathological changes,the positive expression rates of p53 、p21WAF1、PCNA、cyclinA was higher in HP infection group than in HP negative group,while there was significant difference in GC group (P<0.05).

Radiation esophagitis incidence were lower in IFI than in the ENI group,it wa-s statistically significant,P< 0.05.Conclusion IFI for the old patients of advanced NSCLC is well tolerated.

and the total tumor stabilization rates were 86.11% and 70%, respectively, and there were significant differences between the two groups (P<0.05). The life quality had a better improvement in the trial group than in control group (P<0.05).

Conclusion:The expression rates of P-gp and LRP in relapse/refractory patients are higher than those of the initial treatment group. There is no correlation between P-gp and LRP expression in AL.

In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties.

Well known wonderfulG-varieties are those of rank zero, namely the generalized flag varietiesG/P, those of rank one, classified in [A], and certain complete symmetric varieties described in [DP] such as the famous space of complete conics.

In this paper we compute the cohomology with trivial coefficients for the Lie superalgebraspsl(n, n), p (n) andq(2n); we show that the cohomology ring ofq(2n+1) is of Krull dimension 1 and we calculate the ring forq(3) andq(5).

As a corollary we obtain af·g·p·d·f subgroup of SLn(?) (n ≧ 3.

More generally, we prove that if Γ is an irreducible arithmetic non-cocompact lattice in a higher rank group, then Γ containsf·g·p·d·f groups.

This is the report of a well-planned study of 100 cases of atrophic gastritis in Chongqing area including gastroscopic examinations, biopsies, and determinations of the levels of gastric acidity and fasting serum gastrin (FSG) , of the parietal cell antibody (PCA) titer, and of the peripheral blood T cell count (ANAE method) .Atrophic change was limited in the antrum in 89 out of the 100 cases; it involved the antrum and the body of the stomach in lo cases. There was only one case showing distinct atrophic change...

This is the report of a well-planned study of 100 cases of atrophic gastritis in Chongqing area including gastroscopic examinations, biopsies, and determinations of the levels of gastric acidity and fasting serum gastrin (FSG) , of the parietal cell antibody (PCA) titer, and of the peripheral blood T cell count (ANAE method) .Atrophic change was limited in the antrum in 89 out of the 100 cases; it involved the antrum and the body of the stomach in lo cases. There was only one case showing distinct atrophic change on ths mucosa of the body and only mild and superficial inflammation in the antrum. The MAO and PAO of the gastric acid of the patients were lower than that of the control group but the difference was not significant statistically (P<0.05). The FSG level of the patients was much higher than that of the control (P<0.01).PCA was positive in 13% of the patients and 4.4% in the control; the difference was also insignificant. The peripheral blood T cell count was unequivocally lower in the patients than in the control.According to the above data, it is considered that only one case of our series belongs to the A type of Strickland's classification and all the other 99 cases are of the B type. As to the criteria of classification, the location nature and the extent of the pathological process should mainly be considerd. The levels of gastric acidity and FSG can only be used as reference. pCA can be positive in both types A and E, it is valueless as a criterion of classification.

The imfluence of BHA and VB on the carcinogenic effect of AFT were investigated for the study of chemoprevention of AFT. 200 male wistar rats were divided into 4 groups of 50 animals each: (1) AFT group, (2) AFT + VB2 group, (3) AFT+BHA group, (4) controlled group. AFT was dissolved in DMSO (40 ug/0.1ml) and injected intraceritoneally to the rats of the 3 experimental groups twice a week in the same close. VB2 was dissolved in drinking water (50 ppm), BHA was incorporated into the basic diet (2.5-5g/kg) and...

The imfluence of BHA and VB on the carcinogenic effect of AFT were investigated for the study of chemoprevention of AFT. 200 male wistar rats were divided into 4 groups of 50 animals each: (1) AFT group, (2) AFT + VB2 group, (3) AFT+BHA group, (4) controlled group. AFT was dissolved in DMSO (40 ug/0.1ml) and injected intraceritoneally to the rats of the 3 experimental groups twice a week in the same close. VB2 was dissolved in drinking water (50 ppm), BHA was incorporated into the basic diet (2.5-5g/kg) and fed to the rats ad libitum. The rats of comtrolled group were given (i.p.) the same volume of DMSO only.In a period of 2 years, 73 tumors were found in 57 rats of the 3 experimental groups. The comtrolled froup showed no tumor. In the AFT + BHA group, the incidence of hepatocellu-lar carcinoma (HCC) (13.33%) was much lower than that in the AFT group (56,25%)(P< 0.05), the frequency (27,08%) and size (0.08±0.24mm2/cm2) of the precanceraus hepatocyte-hyperplastic lesions were much lower than those in the AFT group (45.71% 2.45 ± 7.66mm2/ cm2) (P<0.05). the activity of gamma-glutarnyl transpeptidase (r-GT) in liver tissue of group (2.62±0.46 u/g) was somewhat lower than that of the AFT group (3.84±0.56) (P>0.05). On the contrary, the above parameters in AFT + VB2 group were higher than those in the AFT group (p>0.05). The incidence of tumors other than HCC in AFT + BHA group and AFT + VB2 group was the same (41.94%), but it lower than that in the AFT group (60.71%)(P>0.05). Furthermore, the incubation period of the HCC and other tumors was significantly prolonged in the AFT + BHA group.These results showed that BHA has a marked inhibitory effect on the hepatocarcinogenesis of AFT in rats, whereas VB2 seemingly enhances it. They suggest that BHA may be a useful chemo-inhibitor for the prophylaxis of HCC in high incidence areas where AFT contamination is severe.

65% hepatectomy was performe don 200 rats divided into 3 groups. A preliminary obliteration of the porta hepatis was applied in two groups in different time (30 and 20 mi- nutes respectively),and the other group was used as a control.The regeneration of the liver and survi- val rate were observed in each group. The survival rate was signifi- cantly low in the two groups with preliminary obliteration of the porta hepatis (P<0.01) but not affected by the duration of obliteration(P> 0.05)The hepatic regeneration...

对200只大鼠分三组作了65％肝叶切除术,其中两组在切肝前作了肝门管(肝 A、门 V 和胆总管)不同时间(30或20分钟)的阻断,另一组作为对照组。观察术后肝再生情况和动物存活率。结果表明:肝门管阻断组动物术后存活率明显低于不阻断组(P<0.01)而阻断肝门管的不同时间(30或20分钟)对存活率没有明显影响(P>0.05)。三组动物术后肝再生情况基本相同。
