Lung cancer is one of the commonest of malignant tumor in the world.It is a major threat to human health in China with highest morbidity and mortality.Steady increase in incidence rates have been observed worldwide in the last few decades in young patients,but previous studies have provided conflicting data about the clinical characteristics and prognoses of young patients with lung cancer.Consequently,we have difficulty in comparing their results with each other,as the cutoff ages defining"young"were different in each study.Therefore,this article focuses on the clinical characteristics and the different results of researches for the young patients with primary lung cancer.

This paper is aimed to study the differences of allelopathic effects of Panax notoginseng under different allelopathic chemicals resources and selection of appropriate rotation crops. The additive main effects and multiplicative interaction ( AMMI) model had been used to evaluate the stability of allelopathic effects of P. notoginseng on the varieties of corn, wheat and rice properly. The model could use not only to evaluate the stability of non-regional trial data but also explore the interaction between the rotation crop genotypes and donor substances more efficiently. Meanwhile, correspondence analysis can be used in the AMMI to evaluate genotype stability and donor substances. Ejingza No. 1 (g6) had stronger allelopathic effects with high stability, but Yunrui No. 1 (g9) which was appropriate rotation crop genotype, had weaker allelopathic effects with high stability. These findings will aid in choosing appropriate rotation crops and establishing proper rotation system.

Objective To study and compare the protective effects of pmtease inhibitor and corticosteroid on endotoxin-indueed acute lung injury in order to guide the choice of appropriate drugs. Method Thirty-two New Zealand rabbits were randomly divided(random number) into four groups with 8 rabbits in each, namely normal controls(C) ; lipopolysaecharide(LPS) group(L) ; ulinastatin(UTI) group(U) and dexamcthasone(DEX) group (D) .Except group C, all rabbits were injected with a dose of LPS 600 μg/kg iv. Meanwhile the rabbits in group U,group D received UTI(100 000 μ/kg), DEX(5 mg/kg), respectively. The specimens were collected 4 hours later for detecting the levels of TNF-α and NO in serum, and blood gas analysis, histological manifestations, the lung wet/dry weight ratio, lung tissue MPO and SOD activity, lung tissue MDA. Data were analyzed by ANOVA (SNK- q test), and P < 0.05 was considered as significantly different. Results Compared with group C, the lungs of the rabbits in group L had inflammatory granulocyte infdtration, diffused alveolar septum thickening and hemorrhagic spots were observed in pathological examinations. The histological changes of group U and group D were much lessened than those in group L. As groups U and D were compared with group L, there were significant differences inmany biomarkers including lung wet/dry weight ratio[(5.02±0.11),(4.93±0.13) vs.(5.37 ±0.29)],lung tissue MPO activity[(0.51 ± 0.05),(0.54±0.07) vs.(0.82 ± 0.09)] and MDA[(0.82 ±0.05),(0.81 ±0.04) vs.(0.96±0.05)], NO[(296.2± 11.7),(291.7 ± 15.8) vs.(351.8±19.6)] and TNF-α[group D(2.021 ± 0.122) vs. group L(4.999 ± 0.139)],lung tissue SOD activity[(120.3 ± 6.1),(122.6±3.5) vs.(105.1 ± 8.5)] and blood gas analysis[pH(7.30±0.23),(7.30±0.17) vs.(7.22±0.45) and PaO_2( 101.9 ± 6.8).( 102.5 ± 4.7) vs.(80.3 ± 3.3)] ; but there were no differences of above mentioned biomarkers between group U and D( P > 0.05). And there were no significant differences in PaCO_2 betweeu group U and D and group L[(37.0 ± 3.3),(37.6 ± 3.0) vs.(34.8 ± 2.3)]( P > 0.05). Conclusions The protective effects of ulinastatin on endotoxin-induced acute lung injury is comparable to those of dexamethasone, thus the former may be a clinical substitute for the latter with less side effects.

Objective To discuss the surgical treatment for huge hepatoblastoma in children,and the technique of hepatectomy without blockade of the blood supply to the remained liver lobes.Methods We reviewed 12 cases of huge hepatoblastorna who had been operated from July 2001 to January 2009 in our hospital.The mean age of the children was 3.2 years(range,11 months to 12 years).The diameter of the tumor was from 10 to 23 cm.3～7 cycles of chemotherapy was routinely administrated before operation.When the tumor reduced to a certain size that radical resection could be performed safely,regular hepatectomy was conducted.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes was performed in every patient.Results The operations were successfully accomplished in all the 12 children.5 cases received right trihepatectomy (segment Ⅳ,Ⅴ～Ⅷ),4 cases received right hemihepatectomy(segment Ⅴ～Ⅷ),and the other 3 cases received Ⅳ,Ⅶ,Ⅷ segmentectomy,right Ⅴ,Ⅵ segmentectomy,and left hemihepatectomy respectively.The intraoperative hemodynamic parameters were stable,and there was no perioperative mortality.Postoperative chemotherapy wag routinely administrated.The follow-up period varied from 2 to 92 months.11 children survived and were disease free,among those 6 children have survived for more than 5 years.One child had brain and lung metastasis 5 months post operation,and died 7 months post operation. Conclusion Preoperative chemotherapy administrated to children with huge hepatoblastoma can reduce the tumor size and render tumor reseetable.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes is a safe and feasible surgical technique.

Objective To set up the molecular cytobiological model of endogenous coagulation factor Ⅷ (FⅧ) re-expressing in human liver cells L02,and to study the regulation pathway and molecular basis of the re-expression of FⅧ in L02 cells activated by NO signal.Methods The L02 cells at logarithm growth phase were selected and randomly divided into blank control group and experimental group, inhibitor group and inhibitor control group;they were cultured for 0,12,24,36,48,and 60 h.Flow cytometry was used to detect the expression of human FⅧ protein in L02 cells after treated for 48 h.Griess experiment was performed to detect the levels of NO in L02 cells at different time points;the transcription levels of human FⅧ gene,iNOS gene,NF-κB1 gene and I-κB alpha gene were detected by RT-PCR method.Western blotting method was used to detect the expression levels of human phosphorylated I-kappaB (phosphorylated I-κB)in L02 cells.Results The results of flow cytometry showed that the expression of human L02 FⅧ protein was found after treated with L-arginine for 48 h. The Griess results showed that the levels of NO in L02 cells in experimental group were significantly increased at 3,6,12,and 24 h (P<0.05)and the levels of NO in blank control group,inhibitor group and inhibitor control group had no changes. The RT-PCR results showed that the transcription of human FⅧ mRNA in L02 cells was found in experimental group,but there was no transcription of human FⅧ mRNA in blank control group,inhibitor group and inhibitor control group;the transcription levels of iNOS,NF-κB1 and I-κB alphain experiment group were increased(P<0.05)and the transcription levels of these genes in blank control group,inhibitor group and inhibitor control group had no changes. The Western blotting results showed that after adding L-arginine the expression level of phosphorylated I-κB was significantly increased (P < 0.05 ), other groups had no such change. Conclusion L-arginine can activate the phosphorylation of I-κB by NO signal pathway to lead to the changes in the expression of human FⅧ gene promoter upstream regulatory-related transcription factors NF-κB to activate the expression of human FⅧ in human liver cells L02.

By using a micro-sensor through an endoscope,the esophageal variceal pressure in 94 patients with cirrhosis was measured.The results of the measurement were as follow:in 5 cases with Ⅱ-degree,it was 2.68?0.18 kPa,varices in 26 cases with Ⅲ-degree,it was 2.90?0.23 kPa,while in 63 cases of Ⅳ-degree varices,it was 3.51?0.33 kPa.The results suggested that there was a significant correlation between the pressure of esophageal varices with the degree of varices (r=0.313,P=0.01).The method seemed to be a valuable non-invading technic for evaluating the degree of varices.
