Objective To study the effect of recombinant rat augmenter of liver regeneration (rrALR) on proliferation and apoptosis of renal tubular cells in vitro. Methods The cultured human renal tubular cell line (HK2 cells) was divided into several groups with various concentration of gentamicin(GM) or/and rrALR. The proliferation of HK2 cell was evaluated by 3H-TdR incorporation. The apoptosis of HK2 cells was assessed by AO/EB staining and flow cytometer using Annexin V-FITC and propidium iodide (PI) staining. Results (1 ) rrALR promoted HK2 cell proliferation in a time-dependent and dose-dependent manner. The proliferative effect was significant with the concentration from 25 ng/ml to 50 ug/ml (P

Objective To clarify malaria infection and the incidence in first Chinese medical team of United Nation peacekeeping mission in Democratic Republic of Congo and evaluate the effect of prevention measures so that provide reference for studying on malaria prevention and the precautionary measures for the follow-up personnel in Africa. Methods 43 cases (male 30, female 13) were observed between Apr. and Dec. 2003 when they were deployed in D.R.of Congo. Eliminating mosquito was used to decrease the density, including the usage of driving mosquito machine, killing mosquito lamp and chlorine cyanogens chrysanthemum ester, ”Prevent malaria-3”and COTECXIN as the precautionary medicines. Plasmodiums in blood were checked periodically. The cases with positive result of blood test and without clinical symptom was considered as infection, otherwise as disease with symptom appeared. Results The density of mosquito in house decreased. 3 cases (male 2, female 1) suffering from malaria, the incidence was 6.98%. Plasmodium was found in 39 individuals (male 26, female 13), the infection rate was 90.70%. The incidence was the lowest compared with contingents from other countries. Conclusion It was effective that these measures taken by reducing mosquito density and ”Prevent malaria-3”and COTECXIN usage in Chinese medical team during peacekeeping mission .

Objective To explore the relationship among just-world belief,optimism and life satisfaction in colleges.Methods According to convenience sampling principle,370 colleges were selected and assessed with the just world scale for college students (JWS),satisfaction with life scale (SWLS) and the life orientation test-revised (LOT-R) ;and data were analyzed using correlation analysis and regression analysis.Results ①The scores of just-world belief,optimism and life satisfaction were (3.22 ± 0.46),(3.50 ± 0.57),and (3.70 ± 1.21),all of which were higher than middle points.②The scores of just-world belief were positive correlated with the scores of optimism and life satisfaction (r =0.44,0.36,P ＜ 0.01),and the scores of optimism also were positive correlated with life satisfaction(r =0.38,P ＜ 0.01).③ The just-world belief and optimism can positively predict life satisfaction directly(β =0.24,0.29,P ＜ 0.01),and the two factors had interaction(β=0.09,P＜ 0.05).Among optimistic students,life satisfaction of low just-world belief ones were much worse than that of high just world belief ones.However,among pessimistic students,the differences of life satisfaction between high and low just-world belief ones became little.Conclusion Just-world belief of colleges has significant predictive effect on life satisfaction,and the two factors had interaction.

Objective To investigate the protective effects of recombination rat augmenter of liver regeneration (rrALR) on tubular cell injury and renal dysfunction in rats with acute renal failure (ARF)induced by gentamicin. Methods One hundred fifty female Wistar rots were randomly divided into 5 groups: group A (control), group B (gentamincin 140 mg/kg+ saline 100 μg/kg), group C (gentarnincin 140 mg/kg +blank plasmid 100 μg/kg), group Dl (gentaminein 140 mg/kg+rrALR 80 μg/kg), group D2 (gentamincin 140 mg/kg +rrALR 160 μg/kg). Rats were sacrificed at day 4, 8, 12, 16 and 21 after gentamicin first injection. Blood urea nitrogen (BUN), serum creatinine (Scr) and urine N-aeetyl-β-D-glucosaminidase (UNAG) were measured. The histopathologic changes were observed by periodic aeid-Schiff (PAS) staining. Protein expression of ALR and PCNA in renal tissue was detected using immtmohistochemistry and Western blot. Results Compared with control rots, the levels of BUN, Scr and UNAG were significantly increased in ARF rats at day 4, 8, 12 and 16 (P<0.05), however, the renal dysfunction and the renal histopathologieal injury were significantly improved in ARF rats simultaneously administered with rrALR (group D) compared with ARF rats (group B and C). The protein level of ALR, the number of PCNA positive tubular ceils and the proliferation index (PI) in group D were significantly higher than those of group B and C (P<0.05). Conclusion rrALR can promote the regeneration of tubular cells in nephrotoxie ARF rats and ameliorate renal dysfunction.

AIM: To investigate the role of hydrogen sulfide (H_2S) in the cholecystokinin octapeptide (CCK-8) attenuating lipopolysaccharide (LPS)-induced lung injury. METHODS: A rat model of lung injury induced by intravenous injection of LPS was developed. Male Wistar rats were divided into normal control group, LPS group, LPS+CCK-8 group and CCK-8 group. Six hours after LPS injection, partial pressure of oxygen in the arterial blood (PaO_2), H_2S content and cystathionine-γ-lyase (CSE) activity in lung tissue were detected. The mRNA expression of CSE in lung tissue was determined by RT-PCR;the structure of lung tissues was observed under optical microscope. RESULTS: Compared to normal control rats, the LPS-treated rats had significantly decreased PaO_2 level, increased index of quantitative assessment (IQA) score, while H_2S content, CSE activity and the mRNA expression of CSE in lung tissue were significantly increased (all P<0.05). Administration of CCK-8 into LPS-treated rats increased the PaO_2 level and alleviated the degree of lung injury (measured by IQA score). In addition, CCK-8 decreased H_2S content, CSE activity, and the mRNA expression of CSE (all P<0.05). No significant difference of the above-mentioned parameters between CCK-8 group and normal control group was observed. CONCLUSION: CCK-8 reduces LPS-induced lung injury through inhibiting the generation of endogenous H_2S.

Objective To investigate the time and dose dependent effects of 17 β-estradiol ( E2 ) on eNOS phosphorylation and nitric oxide (NO) production from bovine aortic endothelial cells (BAECs). Methods The BAECs were cultured in 24-well flat plate.The dose dependent rapid induction of NO release by E2 in the BAECs was explored,and the non-genomic mechanism was studied. Each experiment was repeated for 3 times. The NO level was quantified by the electron spin resonance spectroscopy(ESR)method,and the phosphorylation of eNOS were determined by Western blot. Results NO release increased time dependently from BAECs after treatment with E2 at 100 nmol?L-1 at 1,5,10 and 15 min,and the effect peaked at 10 min.There were dose dependent effects of NO production as well as eNOS phosphorylation after treatment with E2 at different concentrations for 10 min,and the effect was the most obvious at the concentration of 100 nmol?L-1 .Upon treatment with equal volume of saline,E2 and actinomycin D (25 μg?mL-1 ) for 10 min,the NO release was(5.38±2.35),(10.59±3.28)and(10.68± 3.31) nmol?mg-1 ,respectively,and the eNOS phosphorylation level was 0.36±0.03,0.98±0.08 and 0.99±0.08,respectively. Compared with 0.9% sodium chloride solution,the NO release and eNOS phosphorylation were significantly increased in E2 treated cells(all P<0.05). Conclusion 17 β-estradiol at 100 nmol?L-1 induced eNOS phosphorylation as well as NO production from bovine vascular endothelial cells through non-genomic mechanism.The effect peaked at 10 minutes.

AIM:To investigate the effects of recombinant rat augmenter of liver regeneration (rrALR) on apoptosis of renal tubular cells (NRK-52E cells) induced by gentamycin sulfate (GM). METHODS: The cultured NRK-52E cells were divided into four groups: normal control cells, cells with GM (GM 1.6 g/L) or GM and rrALR (15 mg/L or 25 mg/L) treatments. The apoptosis of cultured cells were assessed at 24 h, 48 h by AO/EB staining, DNA agarose gel electrophoresis analysis and flow cytometry using Annexin V-FITC and propidium iodide (PI) staining. The protein and mRNA expressions of Bcl-2 and Bax were detected by Western blotting and RT-PCR, respectively. RESULTS: (1) rrALR inhibited NRK-52E cells apoptosis induced by GM (P
