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.

Phospholipid fatty acids are the major constituents of the membranes of all living cells, and different groups of microorganism synthesize a variety of PLFA through various biochemical pathways. Several PLFAs can be used as "signatures" to analyze changes in microbial biomass and microbial communities structure. More and more PLFA method was used in soil microbial analysis. This article briefly reviewed the applications of PLFA methods in soil microbial analysis.

As to a nitrite-oxidizing bacterium screened in our laborator y, the effect of pH, nitrogen sources, carbon sources and sodium chloride on its g rowth was studied in order to obtain high cell density. It showed that the cult ure conditions of nitrite- oxidizing bacterium were 4500mg/L sodium nitrite, 1 .5g/L sodium carbonate, 0~0.5% sodium chloride and 0~0.1% glucose at 28℃~30 ℃, 110 r/min and pH 8.0~8.5. After cultivation for 9 days, the bacteria conc entration reached 4.6?109 MPN/mL and all NO-_2-N in the medium w as converted to NO-_3-N. But the transformation of nitrogen sources was inhibited while the sodium chloride concentration exceeded 0.5% or glucose con centration exceeded 0.1%. According to the test of NO-_2-N conversion with nitrite-oxidizing bacteria in a freshwater aquaculture pond, NO-_2 -N began to decrease on the third day of the moculation of this bacterium and t he concentration dropped from 1.47mol/L to 0.49mol/L after 18 days at 25℃ and pH 8.6.

Objective:To explore the cooradinative training model of postgraduate and and residency of nuclear medicine based on the ability promotion. Develop the learning of basic medical imaging knowledge, the training of clinical practice, the development of scientific research ability and the training of new technology and so on.Methods: Bibliometric analysis was used to analysis the domestic and overseas current situation and research hotspot about carrying out the training of clinical medicine and residency.

Functional constipation(FC) in childhood is characterized by a low defecation frequency in combination with either involuntary loss of stools(encopresis),passage of large amounts of stool,retentive posturing,or hard and often painful defecation.It represents 3%-5% of general pediatric outpatient visits and up to 25% of pediatric gastroenterology consultations.FC is a diagnosis made by history and physical examination.No testing is necessary or desirable.The decision to seek medical care for symptoms arises from a parent′s or caretaker′s concern for children.The caretaker′s threshold for concern varies with his or her experiences and expectations,coping style,and perception of illness,till now there is not an universal native criteria established in spite of much has been done in it.The criteria used are still to draw assistance from the foreign standard,among which the classic criteria,the Rome Ⅱ and Rome Ⅲ criteria are considered commonly used.The purpose of this paper is to descript the several foreign criteria,and to make comparison among them,and to explore their applicability and effectiveness in childhood FC

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.

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.
