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 Study the production of the?-lactamases in eight pan-resistant citrobact- er freandi and their epidemic characteristics.Methods Modified Hodge test and EDTA-disk syner- gy test were used to screen Metallo-?-lactarnases,and isoelectric focusing to estimate the production of ESBLs and AmpC enzymes.ESBLs,AmpC,MBL genes were amplified and analyzed by PCR and DNA sequencing.Molecular epidemics were investigated by PFGE.Results All the 8 strains pro- duced TEM-1,CTX-M-14,4 of them at the same time producing CTX-M-3.No Plasmid mediated AmpC was found.Furthermore,a new subtype of MBL with one amino acid different from IMP-8 was de- tected.All the 8 strains belong to the same PFGE type.Conclusions Pan-drug-resistant citrobacter freundi produced more than one kind of?-lactamases.All these isolates were clonally related.

OBJECTIVE To explore the relationship between allergic rhinitis and IFN-?, IL-12. METHODS The expression of IL-12 was detected by in situ hybridization and enzyme-linked immunosorbent assay in 37 patients with allergic rhinitis and 12 control samples. IFN-? was detected by ELISA. RESULTS The positive ratios of IL-12 in PBMC were 0.13?0.03 and 0.77?0.15 in allergic rhinitis group and control group respectively. The concentrations of IL-12 were (13.7?2.4 ) pg/L and (52.9?8.4 ) pg/L in allergic rhinitis group and control group respectively. The concentrations of IFN-? were (11.2?2.1 ) pg/L and (51.8 ?6.4) pg/L in allergic rhinitis group and control group respectively. CONCLUSION The down-regulation of IL-12 and IFN-? was related to allergic rhinitis, and hyper-function of Th2 cells may play an important role in the pathogenesis of allergic rhinitis.

Objective The Rex shunt has been used to treat children with extrahepatic portal hypertension by creating a venous bypass between the superior mesenteric vein and the left portal vein to circumvent the extrahepatic portal venous obstruction.This retrospective study aimed to analyse our results in the use of this novel approach.Methods 52 patients with cavernous transformation and obstructed main portal veins were treated by Rex shunts.Results The age of children was 1.4 ～ 12 year,the mean age was 3.7 years.The patients were followed up from 1.5 to 5 years.In 48 patients,there was no recurrence of gastrointestinal bleeding after surgery making an efficacy rate of 92.3％.In the recurrence group,the postoperative venous pressure in the superior mesenteric vein was (27.6 ± 3.2) cmH2O (1 cmH2O =0.098kPa) which was significantly higher than the non-recurrence group (23.5 ± 3.1)cmH2O.The difference between the pre-and post-Rex shunting was significantly lower in the recurrence group (5.7 ± 1.8)cmH2O than the non-recurrence group (11.7 ± 3.3) cmH2 O,P ＜ 0.05.Thus,a low reduction in postoperative pressure was an early manifestation of poor prognosis.Conclusions The Rex shunt was safe and efficacious.The degree of reduction in postoperative venous pressure in the superior mesenteric vein could be used to predict recurrence of gastrointestinal bleeding.

Objective To explore the protective effect of folic acid supplementation in different ways on lipopolysaccharide-induced external malformations and skeletal malformations in mice.Methods The pregnant mice were divided into six groups randomly,including saline control group,FA control group,LPS group,LPS+FAig group,LPS+FAip group,and LPS+FAdw group.All dams were medicated on gestational day 8～12,and then sacrificed on gestational day 18,for each litter,the number of live fetuses,dead fetuses,resorption fetuses and external malformations of live fetuses were all counted.All fetuses were subsequently evaluated the skeletal malformations.Results A low dose of LPS injection during the second trimester resulted in external and skeletal malformations.Exencephaly and encephalomeningocele were two of the most common external malformations,skeletal malformations consisted mainly of the incompletion of supraoccipital ossification,sternal malformation and rib malformation.FA supplementation by three ways all attenuated the external and skeletal malformations.And the best protective effect was by oral administration.The incidence of external,sternal and rib malformation was all decreased.Conclusions Three ways can prevent the mice during the second trimester from the external and skeletal malformations caused by LPS injection,and the best protective effect was by intragastric administration.

Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P<0.05). The patients with dissected LNs counts of more than 11 for cases with pTl~2 tumor (P<0.05) and more than 16 for cases with pT3 tumor (P<0.05) had better long-term survival outcomes. The post-operative complication rate was 12.1%, which was not significantly correlated with the number of dissected lymph nodes (P>0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.
