Hepatocyte growth factor participates in many gynecologic and obstetric diseases such as gynecological tumor,endometriosis and hypertensive disorder complicating pregnancy by combination with its receptor c-Met.This article reviews the expression and mechanism of HGF in these diseases.

OBJECTIVE: To explore the anti-tumor and immunologic enhancement effects of Xiangling capsule.METHODS: The tumor-inhibition experiment was conducted in vivo in accordance with the screening criteria of anti-tumor drugs.Mice were treated with cyclophosphamide to induce hypoimmunity model.The effect of Xiangling capsule on mice was tested by determining leukocyte count,thymus index,spleen index,and the activity of NK cells.RESULTS: Xiangling capsules at different concentration showed inhibition on the growth of mice-transplanted tumor S180,H22 hepatomas and Lewis lung carcinoma with inhibition rates of 44.8%,52.2 %,and 43.3%,respectively(P

OBJECTIVE:To promote the implementation of essential medicine system by combining drug utilization research with national essential medicine system. METHODS:The importance of information monitoring in the implementation of essential medicine system was analyzed and the application of drug utilization research in the implementation of essential medicine system was also discussed. RESULTS & CONCLUSIONS:It is suggested that the indicators for example DDDs are used in the monitoring of clinical drug utilization,and conditions also should be created to carry out further research of drug utilization so as to promote the implementation of essential medicine system in China.

At the beginning of the 1980s, a concept of viable but non-culturable(VBNC) was suggested. VBNC is a survival strategy adopted by microorganisms when they are exposed to environmental stress. This article try to make a summary of research of the conditions of VBNC formation, recovery of culturability and methods of VBNC cells detection. In addition, introduces the first growth factor of microorganisms-Rpf.

Urid acid is one of the terminal metabolites of human body.More and more attention was paid to its metabolic mechanisms in intestinal tract;however, few studies were seen so far.This study aims to illuminate the metabolic mechanism of uric acid in intestinal tract by two ways:one is the transporters associated with intestinal epithelium, including ABCG2 and SLC2A9, the other is decomposition of uric acid by intestinal flora.We hope this review can provide new insights to decrease blood uric acid and treat urate-related diseases, and also provide a new way to alleviate drug-induced kidney damage.

Objective To observe the effect of sequential selection catheter combined with anisodamine in neurology catheterization patients about urine leakage to seek a new care pathway.Methods 240 cases of hospitalized neurology patients with indwelling catheter for a long time were randomized.The control group received conventional fixed-size catheter.According to the individual patient situation,the observed patients choose smallest model applicable Foley catheter when the initial catheterization,and increase the model sequential in turn periodic replacement of the catheter.The patients with leakage of urine were given anisodamine 10mg intramuscular injection,observe urine leakage rate of patients.Results The urine leakage rate was 6.67％ in the observation group which was significantly lower than 20.83％ in the control group(x2 =10.15,P ＜ 0.05),the intramuscular anisodamine efficient was 32/33 (96.97％).Conclusion Sequential selection catheter can significantly reduce the occurrence of urinary leakage,for patients with leakage of urine,anisodamine intramuscular injection can effectively control the leakage of urine,thereby greatly reducing the patient's pain.

Objective To explore the mechanism of lymphotactin(LTN) to exert mucosal adjuvant activity. Methods Complexes of chitosan-pVP1 and chitosan-pLTN were seperately prepared by co-cojugation method, then 50μg(DNA) of each complex was administered intranasally to male BALB/c mice 4times biweekly. Two weeks after the final immunization, mice were challenged with 3LD50 CVB3 to cause viral myocarditis, heart histopathological changes were examined 7 days later. Meanwhile, T cell immune responses, DC percentage and its membrane CD86 expression were monitored in spleen, mesenteric lymph node(MLN) and cervical lymph node(CLN). Results Co-immunizaiton with LTN remarkbly alleviated CVB3-induced cardial injury. This improvement was accompanied with enhanced T cell proliferation and IFN-γ-secreting ability, increased DC frequency and membrane CD86 expression both in spleen and mucosal draining lymph nodes( MLN, CLN). Conclusion LTN exerts its mucosal adjuvant function in augmenting specific T cell immune responses systemically and mucosally via DC enrichment in spleen, MLN and CLN and up-regulation of DC maturation.

BACKGROUND:Patellar tendinopathy is tiny damage at tendon insertion.Changes in the strength balance between medial vastus muscle(VM)and musculus vastus lateralis(VL)in the quadriceps may lead to patellar abnormal motion,even have an impact on the tendon insertion.OBJECTIVE:To compare and analyze knee mechanical charactedstics and surface electromyography of the quaddceps in athletes with patellar tendinopathy.in order to provide scientific basis for the prevention and treatment of patellar tendinopathy.DESIGN,TIME AND SETTING:Self-control experiment was performed in Central Laboratory of Physical Education College of Soochow University from June to July 2009.METHODS:A total of 10 athletes with patellar tendinopathy aged(21.44±1.51)yeam were selected as patellar tendinopathy group and 10 normal athletes aged(21.37±1.36)years were selected as normal control.MAIN OUTCOME MEASURES:①Knee flexor and extensor muscles peak torque in concentric and eccentric isokinetic exercise between two groups.②Comparison of quadnceps integrated electromyogram(IEMG)between two groups.③Comparison of VM/VL in different kinds of exercises between groups.RESULTS:The ratio of flexor and extensor peak torques of the patellar tendinopathy group was significantly greater than the normal group in concentric and eccentric isokinetic exercises(P＜0.05 or 0.01).VM IEMG of the patellar tendinopathy was significantly less than normal group(P＜0.05 or 0.01),but no difference was found in VL and rectus femoris IEMG between two groups.During the period of isometric exercise and isokinetic exercise,the ratios of VM/VL of the patellar tendinopathy group were remarkably lower than the normal group (P＜0.05 or 0.01).CONCLUSION:There are significant differences between flexor and extensor torques in patellar tendinopathy athletes.VM is under-activity and there is an imbalance between VM and VL.

Objective To probe into the mechanisms of bone morphogenetic protein-2 (BMP-2) in osteosarcoma and to provide basis for gene therapy. Methods A 1.0 kb cDNA fragment of human BMP-2 gene was inserted reversely into PDOR and Human antisense BMP-2 retrovirus expression vector was constructed. The recombinant retroviral vector was transfected into human osteosarcoma cells OS-9901 with liposome AMINE that expressed abundant BMP. Positive cell clones were selected with G 418. The expression of BMP and proliferating cell nuclear antigen (PCNA) was determined by immunohistochemical ABC methods. The osteosarcoma cell cycle was analysed by flowcytometry, and the changes were observed by electronmicroscope. Results The expression of cellular BMP and PCNA in the transfected osteosarcoma cells decreased obviously (t=24.01， 26.09, respectively, P
