AIM： To establish th..th.rapeutic potential of proteasome inhibition, we examined th..th.rapeutic effects of MG132 （Z-Leu-Leu-Leu-aldehyde） in an experimental model of acute pancreatitis. MEthODS： Pancreatitis was induced in rats by two hourly intraperitoneal （ip） injections of cholecystokinin octapeptide （CCK; 2×100μg/kg） and the proteasome inhibitor MG132 （10 mg/kg ip） was administered 30 min after the second CCK injection. Animals were sacrificed 4 h after the first injection of CCK. RESULTS： Administering the proteasome inhibitor MG132 （at a dose of 10 mg/kg, ip） 90 min after the onset of pancreatic inflammation induced the expression of cell-protective 72 kDa heat shock protein （hSP72） and decreased DNA-binding of nuclear factor-κB （NF-κB）. Furthermore MG132 treatment resulted in milder inflammatory response and cellular damage, as revealed by improved laboratory and histological parameters of pancreatitis and associated oxidative stress. CONCLUSION： Our findings suggest that proteasome inhibition might be beneficial not only for the prevention, but also for th..th.rapy of acute pancreatitis.

In order to investigate the characteristics and mechanisms of subthreshold voltage hysteresis(ΔV_(th,sub)) of 4 h-SiC metal-oxide-semiconductor field-effect transistors(MOSFETs),4 h-SiC planar and trench MOSFETs and corresponding P-type planar and trench metal-oxide-semiconductor(MOS) capacitors are fabricated and *** with planar MOSFEF,the trench MOSFET shows hardly larger ΔV_(th,sub) in wide temperature range from 25 0 C to 300 0 *** operating temperature range is from 25 ℃ to 300 ℃,the off-state negative V_(gs) of planar and trench MOSFETs should be safely above-4 V and-2 V,respectively,to alleviate the effect of ΔV_(th,sub) on the normal *** the help of P-type planar and trench MOS capacitors,it is confirmed that the obvious ΔV_(th,sub) of 4 h-SiC MOSFET originates from the high density of the hole interface traps between intrinsic Fermi energy level(E_(i)) and valence band(E_(v)).the maximumΔV_(th,sub) of trench MOSFET is about twelve times larger than that of planar MOSFET,owing to higher density of interface states(D_(it)) between E_(i) and E_(v).these research results will be very helpful for the application of 4 h-SiC MOSFET and the improvement of ΔV_(th,sub) of 4 h-SiC MOSFET,especially in 4 h-SiC trench MOSFET.

AIM： To examine the effect of acute infection caused by herpesvirus （pseudorabies virus, PRV） on pancreatic ductal secretion. MEthODS： the virulent Ba-DupGreen （BDG） and non- virulent Ka-RREp01acgfp （KEG） genetically modified strains of PRV were used in this study and both of them contain the gene for green fluorescent protein （GFP）. Small intra/ interlobular ducts were infected with BDG virus （10^7 PFU/mL for 6 h） or with KEG virus （10^10 PFU/mL for 6 h）, while non-infected ducts were incubated only with the culture media. the ducts were then cultured for a further 18 h..th. rate of hCO3 secretion [base efflux -λ（B）] was determined from the buffering capacity of the cells and the initial rate of intracellular acidification （1） after sudden blockage of basolateral base loaders with dihydro-4,4,- diisothiocyanatostilbene-2,2,-disulfonic acid （500 μmol/L） and amiloride （200 μmol/L）, and （2） after alkali loading the ducts by exposure to Nh4Cl. All the experiments were performed in hCO3-buffered Ringer solution at 37 ℃ （n = 5 ducts for each experimental condition）. Viral structural proteins were visualized by immunohistochemistry. Virallyencoded GFP and immunofluorescence signals were recorded by a confocal laser scanning microscope.RESULTS： the BDG virus infected the majority of accessible cells of the duct as judged by the appearance of GFP and viral anUgens in the ductal cells. KEG virus caused a similarly high efficiency of infection. After blockage of basolateral base loaders, BDG infection significantly elevated -λB-） 24 h after the infection, compared to the non-infected group. however, KEG infection did not modify -λB-）. After alkali loading the ducts, -λB-） was significantly elevated in the BDG group compared to the control group 24 h after the infection. As we found with the inhibitor stop method, no change was observed in the group KEG compared to the non-infected group. CONCLUSION： Incubation with the BDG or KEG strains of PRV results in an effective i

helicoverpa armigera is a key insect pest of tomatoes reducing drastically yields. the effect of the endophytic colonization of tomato plants by Beauveria bassiana using leaf spray as an inoculation method on damage and survival of h. armigera was assessed in a screen house. Two B. bassiana isolates (Bb 115 and Bb 11) and two tomato varieties (a local variety Tounvi and an improved variety Padma) were included in the study. the adaxial and abaxial leaf surfaces were sprayed at a concentration of 107 conidia/ml and 109 conidia/ml for each isolate and each of the two tomato varieties. thirty days after inoculation, five discs of tomato leaf and tomato root were cut for each isolate, each concentration per isolate and for each variety. the samples were incubated at room temperature (28°C ± 2°C) and periodically checked for fungal growth. Larval survival was checked and a damage assessment was done on tomato flowers and the leaves. the results show that the lowest Mean Survival Times (MSTs) were recorded on larvae feeding on plants inoculated with Bb 11 (4.2 ± 0.8 days against 11.5 ± 0.2 days for control). Compared to the other treatments, low damage rates of the flowers of the improved variety inoculated with Bb 11 at 109 conidia/ml were recorded from the 6th Day After Inoculation (DAI). this rate remains low until the end of treatment. Overall flower damage was lower than leaf damage. the results showed large differences in pathogenicity, with most endophytic isolate belonging to Bb 11 when inoculated at 109 conidia/ml using the leaf spraying technique. Data were discussed with regard to the use of endophytism B. bassiana in an integrated tomato pest control approach.

目的探索阿托伐他汀对野百合碱诱导的肺动脉高压(PAh)大鼠肺动脉平滑肌细胞(PASMC)增殖的影响及其可能的机制。方法将30只雄性成年SD大鼠随机分为3组:对照组、PAh组以及阿托伐他汀组(ATO组),其中15只用于动物实验,另外15只用于细胞实验。PAh组大鼠接受腹腔注射野百合碱建立大鼠PAh模型,ATO组大鼠除了腹腔注射野百合碱之外,通过灌胃接受阿托伐他汀治疗。在野百合碱造模后第4周周末,Western blot检测固醇调节元件结合蛋白1-c(SREBP1-c)、乙酰辅酶A羧化酶1(ACC1)、乙酰辅酶羧化酶2(ACC2)、磷酸化ACC1(P-ACC1)和磷酸化ACC2(P-ACC2)。另外,以肺组织和PASMC内增殖细胞核抗原(PCNA)的表达水平以及3-(4,5-二甲基噻唑-2)-2,5-二苯基四氮唑溴盐(MTT)染色法来评估PASMC增殖水平。结果野百合碱腹腔注射后第4周周末,PAh组的SREBP1-c、ACC1和ACC2在肺组织内以及PASMC内表达水平较对照组降低,而ATO组的水平较PAh组升高。野百合碱干预后,大鼠肺组织以及PASMC内的PCNA、P-ACC1和P-ACC2的表达水平明显增高,而阿托伐他汀可部分逆转这一过程。同时,MTT染色显示血小板源性生长因子(PDFG-BB)干预过后的PASMC的增殖水平较对照组明显增高,而阿托伐他汀可改善这一过程[对照组(0.15±0.01)比PDGF-BB组(0.27±0.04)比10^(-5)mol/L ATO组(0.17±0.02)比10^(-6)mol/L ATO组(0.20±0.04),P<0.05]。结论阿托伐他汀可以改善野百合碱诱导的PASMC增殖,而这一作用可能是由于其调节脂肪酸代谢相关SREBP1-c/ACC通路而产生。
