Objective To investigate the role of intestinal fatty acid-binding protein(IFABP) as a marker in the (early) diagnosis of intestinal ischemia. Methods SD rats were randomly divided into control group and superior mesenteric artery ligation group (SMA group). Blood samples were collected sequentially at pre-operation, 1, 2 and 4 hours after operation for detecting the activity of IFABP, CK, CK-BB and LDH. Results The activity of IFABP in SMA group elevated 1h and arrived to a peak at 2 hours postoperatively. Compared with control group, all the (levels) of CK, CK-BB and LDH in SMA group were elevated progressively with time after operation. Compared with control group, the significant elevation was at 1, 2 and 4 hours after opration. Conclusions I-FABP is a sensitive and specific marker in the diagnosis of intestinal ischemia.

OBJECTIVE To evaluate the current status that nosocomial infection constitutes one of the main problems threatening the safety of hospitalized patients and to set the idea that a good practice of hand hygiene will definitely improve the situation.METHODS The published papers and related regulations in this specific field were reviewed.RESULTS The most common way responsible for nosocomial infection was the transmission of pathogens by hands of medical staff;the detection rate of pathogens was as high as 80% in nursing staff hands,which included Pseudomonas aeruginosa,Escherichia coli and Staphylococcus aureus by rates of 25.9%,22.2% and 14.8%,respectively.CONCLUSIONS It is of great importance to control nosocomial infection by realizing and using the hand hygiene knowledge,which is basic,simple,and practicable.

The osteoclast is a hematopoietic cell derived from CFU GM, which is regulated by systemic hormones, soluble factors in the phase of differentiation, fusion and proliferation. The major singnaling pathways involved in osteoclastic bone resorption and formation in response to cytokine and hormones include cAMP and R PTK. The advances in our understanding of the osteoclast make it possible for us to comprehend the development and the treatment of the bone metabolic diseases.

Objective To observe the difference in serum level of oxidative stress between first diagnosed type 2 diabetes mellitus (T2DM) patients and healthy person with normal glucose,compare the difference in serum level of oxidative stress between T2DM patients with continuous subcutaneous insulin injection (CSII) and multiple subcutaneous insulin injection (MSII),and further explore the possible mechanism of CSII superior to MSII.Methods Sixty patients with first diagnosed T2DM were divided into CSII group and MSII group by random digits table,with 30 patients in each group and given 14 days treatment of CSII and MSII respectively.Thirty healthy person were selected with age and sex matched in same period as control group,then fasting plasma glucose (FPG),2-hour postprandial blood glucose (2 h PG),glycosylated serum protein (GA),fasting insulin (FINS),superoxide dismutase (SOD),reduced glutathione (rGSH) and malondialdehyde (MDA) before and after treatment was measured and analyzed.Results The FPG,2 h PG,GA,HOMA model of insulin resistance (HOMA-IR) and MDA before treatment in CSII group and MSII group was higher than that in control group [FPG:(13.81 ± 3.14),(13.58 ±2.10) mmol/L vs.(5.21±0.42) mmol/L; 2 h PG:(21.72 ±4.43),(22.07 ±3.86) mmol/L vs.(6.19 ± 0.47) mmol/L;GA:(28.74 ± 4.40),(28.83 ± 5.01) mmol/L vs.(13.24± 1.26) mmol/L;HOMA-IR:0.45 ±0.13,0.43 ±0.12 vs.0.20 ±0.15;MDA:(4.37 ± 1.13),(4.44 ± 1.07) mmol/L vs.(2.37 ±0.58) mmol/L] (P ＜ 0.01),and the HOMA model 3 cell function index (HOMA-β),SOD and rGSH was lower than that in control group [HOMA-β:0.98 ±0.17,0.96 ±0.12 vs.1.91 ±0.19;SOD:(29.63 ±9.29),(28.07 ±9.62) mU/L vs.(41.00 ± 12.89) mU/L;rGSH:(157.03 ±46.58),(165.23 ±45.66) ng/L vs.(212.00 ± 61.67) ng/L] (P ＜ 0.01).There was no significant difference between CSII group and MSII group (P ＞ 0.05).The FPG,HOMA-β,SOD and MDA after treatment in CSII group was no significant difference compared with that in control group (P ＞ 0.05).But the FPG and MDA after treatment in MSII group was higher than that in control group(P＜ 0.01 or ＜ 0.05),and the HOMA-β and SOD was lower than that in control group (P ＜ 0.01).The FPG,2 h PG,GA and MDA after treatment in CSII group was lower than that in MSII group (P ＜ 0.01 or ＜ 0.05).The HOMA-β was higher than that in MSII group (P ＜ 0.01).Multi-factor analysis results showed that the HOMA-β and FPG (r =-0.919,P ＜ 0.01),2 h PG (r =-0.904,P ＜ 0.01),GA (r =-0.830,P ＜ 0.01) and MDA (r =-0.653,P ＜ 0.01) was negatively correlated,and SOD (r =0.454,P ＜ 0.01) and rGSH (r =0.394,P ＜ 0.01) was positively correlated.Conclusions Oxidative stress level of first diagnosed T2DM is significantly higher than that of healthy people.Two intensive insulin treatment for first diagnosed T2DM can reduce blood glucose level,oxidative stress levels and improve insulin resistance and β cell function.CSII can effectively reduce blood glucose,reduce the level of lipid peroxidation and improve β-cell function compared with MSII.

BACKGROUND:Biliary stent is widely used in different biliary tract surgeries, and there are some defects in the use of biliary stent. OBJECTIVE:To explore the biodegradability and compatibility of polylactide/glycolide biliary stent. METHODS:The polylactide/glycolide biliary stent was prepared, and immersed in the bile. At 1, 2, 3, 4 and 5 weeks after soaking, eight experimental stents were dried and placed under the scanning electron microscope. In the sterile condition, the stent was implanted under the rat skin. At 1, 2, 3, 4, and 5 weeks after implantation, two rats were sacrificed. The stent was taken out. The appearance of the stent and muscle structure of experimental animals was observed. The gross appearance of stent was observed at different time by scanning electron microscopy. The rate of degradation was calculated. The muscle structure of experimental animal and the stent were understood. RESULTS AND CONCLUSION:At 1 week, stent shape remained almost intact, but the texture became soft;surface roughness and cracks gradual y appeared;stent wal col apse was visible. The stent was completely degraded at 5 weeks. Before degradation, the stent presented clear three-dimensional reticular structure observed by scanning electron microscopy. With the time extended, the stent surface and section corrosion became worsened. By gel permeation chromatography detection, at 1 week of implantation, the molecular mass of the stent declined rapidly, and then gradual y declined. At 2 weeks, the relative molecular mass decreased to 15 000. At 4 weeks, stent mass loss was approximately 40%. Al the experimental animals were survived, no poisoning, al ergy or heat source response. The operative wound was healed wel , and no infection occurred. By histological observation, at 5 weeks, the stent was completely degraded, with a degradation rate of 100%. Surrounding muscles recovered to a normal state. These results indicate that the polylactide/glycolide biliary stent has good degradation in vitro and biocompatibility.

Objective: To investigate the clinical efficacy of remissive stage-reinforcing and acute stage-reducing acupuncture for treating apoplectic myospasm. Methods: Sixty patients with apoplectic hemiplegia were randomly divided into a treatment group of 30 cases and a control group of 30 cases. The treatment group was treated by remissive stage-reinforcing and acute stage-reducing acupuncture and the control group by modern rehabilitation training. Before and after treatment, the degree of spasm, the level of motor function and ability for daily life were evaluated by modified Ashwordth spasm grading, Brunnstrom grading and Barthel index now often used in the rehabilitation field. Results: Remissive stage-reinforcing and acute stage-reducingacupuncture was superior to modern rehabilitation training in relieving apoplectic myospasm. Conclusion: Remissive stage-reinforcing and acute stage-reducingacupuncture has a unique advantage in relieving spasm.

Objective To study the effects of Glycyrrhiza polysaccharide (GP) on immune function in mice. Methods Polysacchayide was extracted from Glycyrrhiza uralensis by water-extraction-alcohol-precipitation method. Ovalbumin was injected to mice as antigens. The mice were randomly divided into four group:low (50 mg/kg), middle (100 mg/kg), high (200 mg/kg) dosage group of GP and normal control group, 12 mice in each group. Four groups were given GP and NS orally for seven days. After the secondary immunization, the level of antibody and the concentration of serum IFN-? were determined. Results The levels of antibodies and cytokines in middle and low dosage group of GP were all significantly higher than those of control group. Conclusion GP could enhance the immune function of mice.

Objective To evaluate the efficacy and safety of Prostant in the treatment of chronic prostatitis. Methods A randomized, double-blind, positive drug-controlled clinical trial method was applied in the study. Through clinical symptoms, signs and expressed prostate secretion (EPS) examination, 80 patients with prostatitis were recruited and randomized into a trial group (60 cases) and a control group (20 cases). The trial group was treated with Prostant, and the control group was treated with wild chrysanthemum suppository. After screening, treatment and follow-up, in the trial group and the control group, the observation on clinical efficacy and safety were evaluated, such as the clinical symptoms, signs, EPS examination, the national institute health-chronic prostatits symptom index (NIH-CPSI) and the blood routine, urine routine, stool routine, the function of liver and kindney, electrocardiograph examination and the side effects. Results After 4-week treatment, the total effective rate was 74.14% in the trial group and 40.0% in the control group, the efficacy of Prostant was superior to that of wild chrysanthemum suppository (P =0.006). There was significant difference in clinical symptoms and NIH-CPSI between pre-treatment and post-treatment in the trial group and the control group (P

KaplanMeier curve and Log rank test were adopted to detect the difference in survival time of skeletal related event (SRE) and survival rate between patients treated with different medicine,and x2 test was uscd to rcveal thc rate difference of pain killing effects and adverse effects.Results 1.The total effective rate of pain killing was 88.9％ and 85％ respectively.The difference had no statistical significance(P =0.467).2.The 1,2 and 3-year-survival rate in zoledronic acid group and sodium ibandronate group was 88.7％,44.4％,24.2％vs 94.7％,40.5％,5.8％.The difference had no statistical significance(P =0.744).3.The 2,3,and 4-year-survival rate in zoledronic acid group and sodium ibandronate group was 70.4％,40.7％,23.1％ vs 85％,46.7％,17.5％.The difference had no statistical significance( P =0.994).4.The 1,2 and 3-year SRE-free overall survival rate of the group with metastasis first to bone only was 92％,50.8％,and 23.8％,while the rate of the group with first metastasis to visceral organs was 85.4％,21.4％,and 5.3％ ( P =0.012).5.The 2 and 3-year overall survival rate of the group with metastasis first to bone only was 95.8％ and 74.2％ respectively,while the rate of the group with first metastasis to visceral organs was 56.5％ and 10.1％ ( P ＜0.001 ).The difference of 4 and 5 had statistical significance.The difference of zoledronic acid group and sodium ibandronate group in rate of adverse effects had no statistical significance.Conclusions Compared to sodium ibandronate,zoledronic acid has no superiority in either delaying the occurrence of SRE or improving overall survival rate.The -2are similar in incidence of adverse effects and pain control.The prognosis of patients whose first presentation is complicated by metastasis to other organs is poor.

Objective To incubate rat neural stem cells (NSCs) with selection-specific inhibitor ( LY294002) of PI3-K, and explore the effects of PI3-K/AKT signal transduction pathway in NSCs. Methods NSCs derived from E15-16 rats were isolated and cultured. After incubation of NSCs with different concentrations of LY294002 (0 to 40 μmol/L), cell survival ( WTS-8 assay), proliferation ( BrdU immunohistochemical identification), differentiation (β Tubulin-III immunohistochemical identification) and AKP phosphorylated protein (Western blotting) were detected. Results The effects of LY294002 on the survival, proliferation and differentiation of NSCs was concentration-dependent. The survival of the NSCs decreased significantly with a higher concentrations of LY294002 (25, 30, 35, 40 μmol/L) (P < 0. 05). The numbers of BrdU positive cells with LY294002 of 30, 35 and 40 μmol/L were significantly smaller than that of the control (LY294002 0 μmol/L) (P < 0.05). The numbers of β Tubulin-III positive cells with LY294002 of 35 and 40 μmol/L were significantly smaller than that of the control (P < 0. 05). The expression of AKT was blocked by LY294002 in a concentration-dependent manner. Conclusion PI3-K/AKT signal transduction pathway plays a vital role in the survival, proliferation and differentiation of NSCs.
