Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

Objective To investigate the significance of serum neuron specific enolase (NSE) in the severity and prognosis assessments of diffuse axonal injury (DAI).Methods The levels of serum NSE were measured by radioimmunoassay (RIA) at 12 hours and 1st,2nd,3rd,7th and 14th days after injury in 79patients with DAI.The relationship of serum NSE level with the severity and the prognosis of DAI were analyzed in the patients with DAI.Another 15 patients with only limb fracture and without hemorrhagic shock treated in the hospital during the same period served as the control group.Results The serum NSE levels of the mild injury group were (10.47 ± 2.75) ng/L,(13.41 ± 3.45) ng/L,(16.41 ±4.14) ng/L,(15.57 ±4.28) ng/L,(7.95 ±2.79) ng/L,and (6.39 ± 1.55)ng/L at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.The serum NSE levels of the moderate injury group were (14.98 ± 3.78) ng/L,(19.88 ± 4.78)ng/L,(22.41 ±5.50) ng/L,(20.11 ±6.60) ng/L,(14.59 ±6.64) ng/L,and (8.31 ±3.83) ng/L respectively at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.While the serum NSE levels of the severe injury group were (27.22 ± 4.54) ng/L,(36.43 ± 10.38) ng/L,(41.32 ± 12.44) ng/L,(43.98 ±9.51) ng/L,(42.22 ± 13.05) ng/L,and (37.59 ± 12.96) ng/L at 12 hours and 1st,2nd,3rd,7th and 14th days after injury respectively.The NSE levels in each time point were significantly higher in the severe injury group than in the mild and moderate injury groups (F within =28.11,P ＜ 0.001 ; F between =57.34,P ＜0.001 ;F interaction =8.21,P ＜ 0.001 ;P ＜ 0.01).Compared with the control group ((6.26 ± 1.35) ng/L),the serum NSE levels of the DAI group were significantly different at 12 hours after injury ((18.16 ± 3.76)ng/L,t =2.938,P ＜ 0.01).At three months after injury,patients were divided into the decreased group (n =9),poor prognoses group (in vegetative state or severely disabled,n =29) and good prognoses group (moderately disabled or completely recovered,n =41) according to the GOS score.The serum NSE levels of the decreased group were (32.07 ± 5.73) ng/L,(43.12 ± 15.04) ng/L,(48.26 ± 14.89) ng/L,(50.47 ±11.05) ng/L,(52.90 ±3.82) ng/L,and (56.17 ± 14.62) ng/L respectively at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.The serum NSE levels of the poor prognoses group were (21.90 ± 4.95) ng/L,(24.13 ± 9.94) ng/L,(26.43 ± 6.99) ng/L,(21.62 ± 9.77) ng/L,(15.80 ± 7.15) ng/L,and (10.16 ± 2.33) ng/L respectively at 12 hours and 1st,2nd,3rd,7th and 14th days after injury.The serum NSE levels of the good prognoses group were (13.61 ±4.56) ng/L,(13.75 ±5.10) ng/L,(14.77 ±5.41) ng/L,(13.47 ±4.49) ng/L,(8.92 ± 5.61) ng/L,and (6.60 ± 2.30) ng/L at 12 hours and 1 st,2nd,3rd,7th and 14th days after injury respectively.At each time point,the serum NSE levels were significantly different in the decreased group than in the good prognoses and the poor prognoses groups (F within =18.70,P ＜ 0.001 ; F between =62.97,P ＜0.001 ;F interaction =11.83,P ＜0.001).Conclusion The serum NSE levels can be regard as an index for judging the injury severity and prognosis of DAI,and can be used to guide the option and adjustment of therapeutic approaches for patients with DAI.

The thermotolerant bacteria which was isolated from the Apple Juice Concentrate(AJC) was investigated by comparison with the standard strain of Aliyclobacillus acidoterrestris DSM3922 using Kirin-medium acidified with malic acid.The results shows the two polluted bacteria isolated from AJC can grow under the temperature of 21?C～55?C and pH of 2.4～6.2,which was corresponded with the characteristics of the thermo-acidiphilic Alicyclobacillus spp..Further more,the cell morphology,colony morphology,cultural characteristics and physiological characteristics tests indicated the two isolated strains of thermotolerant bacteria have obviously similar characteristics with the standard strain of Aliyclobacillus acidoterrestris DSM3922.

The effect of the complement C1q expression on total hepatic ischemia-reperfusion (I/R) injury in rats was investigated. Sixty healthy male Sprague Dawley (SD) rats weighing 180-200 g were randomly divided into 5 groups: sham-operation group (S group, n=12); group of I/R for 1 h (I/R 1 h group, n=12); group of I/R for 3 h (I/R 3 h group, n=12); group of I/R for 6 h (I/R 6 h group, n=12); group of I/R for 24 h (I/R 24 h group, n=12). The hepatic I/R model of rats was established, and liver tissues were obtained 1 h, 3 h, 6 h and 24 h after hepatic I/R, respectively. Furthermore, the tissues were stained using hematoxylin-eosin, and the liver injuries of rats were observed using a microscope. The malondialdehyde (MDA) level and superoxide dismutase (SOD) activity in liver tissue were determined. Real-time polymerase chain reaction (PCR) and Western blotting were used to detect the expression levels of C1q mRNA and protein, respectively. As compared with the S group, the histopathological changes in I/R 1 h-24 h groups were gradually aggravated with the extension of I/R time. As compared with the S group, SOD activity and MDA content in the I/R groups were reduced and increased respectively with the extension of I/R time (P<0.01). Furthermore, the C1q expression at mRNA and protein levels in the I/R groups (especially in the I/R 3 h group) was significantly higher than that in the S group (P<0.05). It is suggested that C1q expression may play a principal role in hepatic I/R injury, particularly at the early stage of perfusion.

OBJECTIVETo study the effect of tea polyphenols (TP) on the apoptosis of germ cells in rats with experimental varicocele.

METHODSThirty-two adolescent male Wistar rats were randomly and equally divided into groups A (sham-operation), B (high-dose TP), C (low-dose TP), and D (experimental left varicocele). Experimental varicocele was induced by partial ligation of the left renal vein in the latter three groups of rats. The animals in groups A and D were fed with normal saline, while those in B and C with TP at 40 and 10 mg per kg per d, respectively, all for 4 weeks. Then, all the rats were sacrificed and the left testes harvested for determination of the expression of HIF-1, Bcl-2, Bax, CytC, and caspase-3 by immunohistochemistry and measurement of the apoptosis index (AI) of spermatogenic cells.

RESULTSThe expression of Bcl-2 was higher in groups B and C than in D but lower than in A (P < 0.05), and lower in C than in B (P < 0.05). However, the expressions of HIF-1, Bax, CytC, and caspase-3 were lower in groups B and C than in D but higher than in A (P < 0.05), and higher in C than in B (P < 0.05). The AI of spermatogenic cells was the lowest in group A, higher in D than in the other groups but lower in B than in C (P < 0.05).

CONCLUSIONTP can reduce the apoptosis of spermatogenic cells in a dose-dependent manner in varicocele rats.

OBJECTIVETo investigate the effects of angiotensin converting enzyme inhibitor (ACEI) captopril on Calpain-mediated cardiomyocytes apoptosis and cardiac function in diabetic rats.

METHODSThirty adult male SD rats were randomly divided into 3 groups (n = 10), normal control group (NC group), diabetes mellitus group (DM group)and captopril treated group (Cap group). Streptozocin (STZ) were used to make the model of diabetes mellitus, captopril was administrated by gavage at the dose of 50 mg/kg every day, while in NC group and DM group the same volume of normal saline was administrated. Twelve weeks later, left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVDEP), maximal rise rate of left ventricular pressure (+ dp/dtmax) and maximal fall rate of left ventricular pressure (- dp/dtmax) were detected; Western blot was used to detect the expression of Calpain-1 Calpain-2, Bcl-2, Bax and total Caspase3 protein; apoptosis index (AI) were assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL).

RESULTSCompared with NC group, LVDEP was significantly higher; LVSP, + dp/dtmax and - dp/dtmax were significantly decreased (P < 0.05); Bcl-2 protein expression was decreased; the expression of Calpain-1, Calpain-2, Bax and total Caspase3 protein were increased; the value of AI was significantly increased. Compared with DM group, LVDEP was significantly lower; LVSP, + dp/dtmax and - dp/dtmax were significantly increased (P < 0.05); Bcl-2 protein expression was increased, the expression of Calpain-1, Calpain-2, Bax and total Caspase3 protein were decreased; the value of AI was significantly decreased (P < 0.05).

CONCLUSIONCaptopril can protect diabetic myocardial structure through inhibiting activation of Calpain-1 and Calpain-2, up-regulating the expression of Bcl-2, down-regulating the expression of Bax to inhibit Caspase3 dependent apoptosis, thereby improving the ventricular function and myocardial structure.

Based on variation of Pinus massoniana families, heritablility and correlation analysis, the contents of shikimic acid and procyanidine (heritability 0.90, 0.70), dry weight of single branch (heritability 0.60) and and leaf length (heritability 0.46) were screened out as quality, yield and harvest cost traits of Folium Pini, respectively. For the different medicinal application of Folium Pini, varied methods were chosen to estimate weight and construct index equation. Weight adjustment based.on equal emphasis were used as economic weight determining method to select the best families, and the index (accuracy 0. 936 4 and heritability 0. 881 6) obtained was a little better than that obtained by equal emphasis, and much better than that by restricted index. The superior families selected with adjustment weight and equal emphasis were No. 46, 43 and 28. Partial regression were used as economic weight determining method to select the best families,and the index obtained had the highest accuracy (0.941 5) , index heritability (0. 889 9) and the genetic gain of shikimic acid content. The superior families selected with this method were No. 46, 27 and 47. No. 46 was the best families with maximal economic benefit. Our study indicated that suitable method for estimate weight and construct index equation can be applied for better accuracy of superior families selection of P. massoniana.
