BACKGROUND: Diabetic glycometabolism disorder and lipoid metabolism disorder are often reciprocal causation, which cause the reduction of hepatic glycogen and the changes of many plasma factors. Hence, the occurrence of vascular complications in heart, kidney and brain is common. It becomes a hot topic in latest researches to find an effective medicine for the secondary prevention of diabetes.OBJECTIVE: To study the interventional effects of leizhusun' s juice on hepatic glycogen, plasma glucose and blood fat.DESIGN: A randomized and controlled observatory study by employing experimental animals as subjects.SETTING: Laboratory of Pharmacy College of Xianning College.MATERIALS: Totally 40 male Wistar rats with a bodymass of (230 ± 20) g were obtained from the Experimental Animal Center of Wuhan General Hospital of Guangzhou Military Area.METHODS: The diabetic rat model was established by the injection of Alloxan(200 mg/kg) into abdominal cavity in the laboratory of Pharmacy College of Xianning University between September 2002 and June 2003. Leizhusun' s juice(LZS) of different doses(205.70 mg/kg and 436. 40 mg/kg) was respectively perfused into the stomach for 28 days, and healthy rats were used as normal control. Levels of hepatic glycogen(HG) in liver and the factors in plasma were detected.MAIN OUTCOME MEASURES: HG, glucose(Glu), triacylglycerol (TG), non-esterified fatty acid(NEFA), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-c), high-density lipoprotein cholesterol (HDL-c), and malondialdehyde(MDA) contents, and superoxide dismutase (SOD) activitiesRESULTS: The level of Glu in LZS-Ⅱ group(436.40 mg/kg) was (9.65± 1.14) mmol/L, TG was(1. 31 ±0. 18) mmol/L, NEFA was(0. 51 ±0. 04)mmol/L, LDL-c was(0.79 ±0. 19) mmol/L, and MDA was(6.31 ±0. 83)nmol/L, which were significantly lower than Glu of (16. 14 ± 1.59) mmol/L,TG of(1.94 ±0. 31) mmol/L, NEFA of(0.59 ±0. 05) mmol/L, LDL-c of (1.34 ±0.28) mmol/L and MDA of(10.95 ±2.90) nmol/L in experimental control(Model) group( t= 3. 478 - 9. 379, P < 0.01), while the HDL-c was (1.09±0.13) mmol/L, SOD was(39.76±6.23) NU/mL and HG was (6.70 ±0.62) mg/g in LZS-Ⅱ group, which were significantly higher than HDL-c of(0.55 ± 0. 11) mmol/L, SOD of (23.24 ± 3.35) NU/mL and HG of (4.06±1.24) mg/gin Model group( t = 5. 388 - 9. 000, P <0.01). Furthermore, the decreasing effect on LDL-c and increasing effect on SOD in both LZS groups had dose-dependence relationship( P < 0.05 -0.01 ).CONCLUSION: LZS significantly decreases plasma Glu, TG, NEFA, LDL-c and MDA levels, but increases HDL-c, SOD and HG levels, which displays obvious antidibetic effects.

Objective To study the effect of mannose receptor(MR) from human spermatozoa on sperm-egg fusion. Methods The Balb/c mouse was immunized with the purified mannose receptor(pMR) which was isolated from motile human sperm by mannose-agarose gel affinity chromatography and the anti-MR serum was harvested. Human sperm after induction of acrosome reaction was pretreated with anti-MR serum and subsequently processed in sperm penetration assay (SPA). Results The anti-MR serum can inhibit human spermatozoa from binding and penetrating zona-free golden hamster eggs with a dose-dependent reduction of Fertilization rate(FR) and Penetration index(PI).Conclusion The results indicate that MR of human sperm plays an important role in sperm-oocyte fusion.

15 oocytes group than in the ≤15 oocytes group. All parients with the acute abdmen caused by ectopic and heterotopic pregnancy had tubal factor causing infertility. The misdiagnostic rate was significantly lower of reproductive-specialty doctors than non-reproductivespecialty doctors. Conclusion Excessive oocytes induced by ovarian hyperstimulation and tubal damage were main risk factors of acute abdomen. To reduce the misdiagnosis, non-reproductive-specialty doctors should know about IVF-ET and patients should be informed about the occurrence of these procedure related complications.

Objective To explore the feasibility of mouse muscle-derived cells with adenovirus-mediated expression of BMP-2 in the treatment of mouse tibia bone defect via collagen sponge as scaffold. Methods Mouse adenovirus BMP-2 plasmids were prepared and identified by PCR.The adherent cells of muscle-derived stem cells cultured in vitro were passaged,cells of the third generation were selected,and recombinant Ad-BMP-2 plasmids were expressed and incubated in mouse myoblasts.The number of BMP-2 positive cells was measured using indirect immunofluorescence method,and alkaline phosphatase(ALP) method was adopted to determine the cell activity in each group.The mouse models of proximal tibial bone defect were established(n=80) and were divided into Ad-BMP-2 transfection group,Ad-LacZ transfection group,blank group and Ad-BMP-2 implantation group.The histological and radiological changes were observed 3 weeks after operation. Results It was revealed by indirect immunofluorescence that BMP-2 positive cells were frequently found in Ad-BMP-2 transfection group,while none were observed in Ad-LacZ transfection group and blank group.The ALP activity was higher in Ad-BMP-2 transfection group,while that was extremely low in Ad-LacZ transfection group and blank group.There was most typical imaging of repair and healing of bone defect in Ad-BMP-2 transfection group,followed by Ad-BMP-2 implantation group,while there was no typical imaging in Ad-LacZ transfection group and blank group. Conclusion The constructed Ad-BMP-2 plasmids can effectively transfect mouse muscle-derived cells,and the transfected cells can continuously express effective amount of BMP-2.The mouse muscle-derived cells with adenovirus-mediated expression of BMP-2 play a definite role in the treatment of bone defect,which provides an effective method and material for clinical application.

Considering a variety of theories such like Dunkin's, Centra's and Kolitch's, a set of 13 indicators are designed to evaluate effect of courses taken in high education of China currently, compro-mised by chief aspects of course designing, practicing, and effect. Three courses including medical nursing, humanistic cultivation and communication skills in nursing and fundamentals of nursing in a nursing de-partment are chosen to be objects of questionnaire survey about the above indicators. The results show that there are significant differences in curriculum effectiveness between different courses. The scores are 2.81, 2.80 and 2.60 respectively, and teachers and students have different evaluation on the same indicators of the same curriculum,which provides a reference for teachers, colleges and universities and teaching management departments to promote the improvement of teaching quality.

ObjectiveTo investigate the clinical effects of androgen blockade combined treatment for the elderly with middle and late prostate cancer.Methods 63 patients (average age of 69.3 years) with middle and late prostate cancer (above stage T3 ) were studied retrospectively from June 2001 to August 2009.21 cases were treated by operation of bilateral orchidectomy independently.15 cases were treated by castration independently (enantone 3.75 mg or zoladex 3.6 mg/month,hypodermic injection for one year).27 cases were treated by bilateral orchidectomy plus maximum androgen blockade (MAB) (bicalutamide 50 mg,qd,fulutimad 250 mg,rid,po.)Results The survival rates of 1,2,3 years were 100.0%,90.0%,75.0% in operation group,100.0%,86.7 %,73.3% in drug group,and 100.0%,96.2%,84.6% in MAB group,respectively.The survival rates of 3 years was higher in MAB group than the other groups(x2 =4.460,P<0.05).The levels of PSA within 3 months decreased and urinary flow rates in three groups increased after treatment than before treatment (t =2.641,3.074,6.703,P < 0.01 ) with no differences among the groups.The relieve period of validity was longer in MAB group than in other groups (F=16.57,P<0.01 ).Conclusions MAB may be more effective for the elderly with middle and late prostate cancer than castration therapy independently.
