OBJECTIVE:To observe the pharmacological effect of Ulinastatin on acute necrotizing pancreatitis in rats.METHODS:Animal models were divided into3groups:group A,sham operation;group B,acute necrotic pancreatitis given no treatment;group C,acute necrotic pancreatitis treated with Ulinastatin.The changes of AMS and TNF-?were compared at different time among3groups.RESULTS:AMS and TNF-?in group C were significantly different from those in group A and in group B.CONCLUSION:Ulinastatin could remarkably improve the prognosis of acute necrotic pancreatitis.

Objective To study the embryotoxicity and teratogenicity of monocrotophos in mice.Methods Sixty pregnant Kunming mice were randomly divided into four groups,15 in each:three groups were exposed to the monocrotophos at the doses of 0.05,0.10 and 0.20 mg/kg,10 ml/kg through gavage,during the period of organ formation(from 7th day to 16th day),once a day and the control group to distilled water.The pregnant mice were weighted in day of 0,6,12,18,and 20,and were sacrificed on 20th day of pregnancy.The numbers of living,dead and absorbed fetus were counted,and the uterus and placenta were weighted.The deformity examination was conducted.Results The maternal body weight of exposure groups were lower than those of control group in 12,18 and 20 day of pregnancy.With the increased doses of monocrotophos,the weights of pregnant mice showed a downward trend.Compared with the control group,the rates of dead fetus and absorbed fetus increased significantly,and the rates of living fetus,the fetal body weight and body length,tail length and placental weight decreased significantly(P

Objective To investigate the differential diagnosis value between breast phyllode tumor and breast fibroadenoma by comprehensive analysis of multiple parameters on color Doppler ultrasonography.Methods The manifestations or characteristics on color Doppler ultrasonography were analysed in 17 cases with breast phyllode tumor and 92 cases with breast fibroadenoma.Results Thinned skin was found in 3 cases of phyllode tumor of the breast(17.65%).Cystic areas were observed in 11 cases with phyllode tumor of the breast(64.71%).Varication inside the tumor was found in 12 cases with phyllode tumor of the breast(70.59%).Conclusions Thinned skin,cystic areas and varication inside the tumor are the important indicators in differential diagnosis for breast phyllode tumor from breast fibroadenoma,which may improve the accuracy of diagnosis for phyllode tumor of the breast.

Objective To investigate the autophagy capacity in clear cell renal cell carcinoma tissue compared with adjacent normal tissue.Methods Sixty-nine pairs of samples from human clear cell renal cell carcinoma tissues and relatively healthy renal tissues adjacent to the tumor were collected during surgical resection.The expressions of proteins that were participating in the regulation and execution of autophagy were detected by immunohistochemisty.Electron-microscopy was also carried out for the morphometrical analysis.Results The protein expression of p-mTOR (P =0.004),P62 (P =0.000) and ULK1 (P =0.000) were up-regulated in the carcinoma tissue,while the expression of Beclin1 (P=0.000),LC3 (P =0.000) and ATG7 (P =0.000) were down-regulated,and the expression of ATG5 (P =0.349) had no signif-icant difference compared with adjacent normal tissue.Morphometrical analysis showed that the basal autophagic activity (measured by the presence of autophagy vacuole compartment) was remarkably down-regulated in carcinoma tissue,compared with adjacent normal tissue.The expression level of mTOR was correlated with P62,LC3 and ATG7,but results showed no correlation between mTOR and Beclin 1.Conclusion Our studies show a relatively reduced autophagy capacity in clear cell renal cell carcinoma,which is regulated by multiple autophagy-related proteins such as mTOR,Beclin 1 and LC3.

Objective To study the clinical and pathological features of primary nephrotic syndrome in elderly patients.Methods Clinical data of patients with primary nephrotic syndrome aged ≥ 60 years underwent renal biopsy were retrospectively analyzed and patients with primary nephrotic syndrome aged ＜60 years were selected as control group.Results Male patients with primary nephrotic syndrome were common in the elderly group and control group,and there was no significant difference in gender composition between the two groups (62.0％ vs.61.5 ％,P＞0.05).The degree of edema and hypertension,levels of blood urea nitrogen,serum albumin,blood IgG and ratio of IgG /IgM were higher while levels of urinary protein and blood cholesterol were lower in elderly group than in control group (all P ＜ 0.05).No significant differences in the incidence of hematuria,serum levels of creatinine,IgA,and complement were found between the two groups (all P＞0.05).The risk of primary nephrotic syndrome was higher in elderly group than in control group (P＜0.01).The level change of blood IgG was positively associated with plasma albumin,while negatively associated with urinary protein and blood cholesterol in both groups (r=0.327,-0.147,-2.860,respectively,all P＜0.05).Membranous nephropathy was the most common type in elderly patients,accounting for 49.77％,while only accounting for 23.6％ in control group,which had a significant difference between the 2 groups (x2 =62.390,P ＜ 0.01).Mesangial proliferative glomerulonephritis was common in both groups,but no significant difference(x2 =62.390,P＞0.05).Conclusions Male patients are more common than female patients in primary nephrotic syndrome.The clinical manifestations including urinary protein and serum albumin are milder but the risk is much greater in elderly patients than in the non-elderly patients.The change of blood IgG level is associated with urine albumin,plasma albumin and plasma cholesterol.Membranous nephropathy is the most common type followed by mesangial proliferative glomerulonephritis in elderly patients with nephrotic syndrome.

Objective To study the gait footprint parameters of the normal children and the cerebral palsy (CP) children, and to explore its clinical value. Methods A total of 2 800 normal children aged 3 to 10 years and 139 spastic CP children aged 3 to 5 years were recruited in this study. The normal children were divided into seven groups with one year interval, and were measured with regard to the length of foot and step, step width and foot angle of footprint of every age group with self made oil printed carpet. The footprint of the CP children were measured and compared with that of the normal children at the same age. Results It was revealed that there was significant difference between the normal and the CP children ( P

Objective To observe the effect of breviscapine on the open probability(Po)and the average open time(To) of L-type calcium channel in the hippocampal neurons of the whole brain ischemia-reperfusion rat model.Methods The whole brain ischemia rat model was established.At the reperfusion periods of 1.5 h,3.0 h,4.5 h and 6.0 h,the hippoeampal CA1 neurons were dissociated abruptly and the Ca~(2+)electricity of single channel on the neuron membrane were recorded with cell-attach model of patch clamp techniques.The Po and To of the L-type calcium channel were an- alyzed and the effect of the breviscapine was observed.Results Different concentrations of breviscapine can decrease the Po and To of the L-type calcium channel in hippoeampal neurons,particularly within 3 hours after ischemia-reperfu- sion.Conclusions Breviscapine has protective effect on the cerebral ischemia-reperfusion injury.

Objective To detect the inhibiting effects of ionizing radiation combined with inhibitors or inducer of autophagy and apoptosis on MCF7 cell line,and to provide the evidence for human breast cancer therapy radiation.Methods MCF7 cells were exposed to X-rays and randomly divided into 4 groups,including 0 Gy,4 Gy,4 Gy+rapamycin,4 Gy+3-MA,and 4 Gy+z-VAD-fmk groups,including 0 Gy,4 Gy,4 Gy+rapamycin,4 Gy+3-MA,and 4 Gy+z-VAD-fmk groups,respectively.The growth doubling time was calculated by MTT method.The specific protein expressions of LC3 autophagy and beclinl were detected by using Western blot and the difference of Drotein contents wasLC3 autophagy and beclinl were detected by using Western blot and the difference of Drotein contents was compared.The percentage of apoptosis of MCF7 cells was measured by flow cytometry (FCM).Resuits The growth doubling time of MCF7 cells in 4 Gy group wag longer than that in O Gy group(t=4.41,P
