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.

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 investigate the accuracy of contrast enhanced ultrasound (CEUS) in diagnosing acute severe panereatitis.Methods Thirty three patients with acute severe pancreatitis were enrolled in the study and all of them underwent CEUS and spiral computed tomography(CT) scan.CT was taken as gold standard in acute severe pancreatitis diagnosis.CEUS were done within 72 hours after CT scan.Results Compared with CT, the sensitivity, specificity,accuracy, positive predictive value,and negative predictive value of CEUS for detecting the necrosis of pancreas were 90%, 95%, 94%, 90% and 95%respectively.The sensitivity, specificity, accuracy, positive predictive value,and negative predictive value of CEUS in diagnosing severe acute pancreatitis were 85%, 92%, 88%, 94% and 80% respectively, while 37% ,86% ,58%, 78%, 50% for conventional ultrasound respectively.Conclusions CEUS is accurate in detection of pancreatic necrosis and diagnosis of acute severe pancreatitis.

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.
