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.

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 observe the mechanism of herbal cake separated moxibustion to hyperlipemia (HLP) and atherosclerosis (AS) rabbits on cell and molecular level. Method 75 rabbits were divided into 5 groups randomly:blank group, model group of HLP and AS, direct moxibustion group, herbal cake separated moxibustion group, herb group, 15 rabbits each group. Model rabbits of HLP and AS were built by immunity injury method. The expression of VCAM-1 mRNA and E-sel mRNA were determined with the method of RT-PCR. Results The expression of E-sel mRNA in herbal cake separated moxibustion group, direct moxibustion group and herb group are obviously decreased (P

Background Keratectasia after laser in situ keratomileusis (LASIK) is one of the serious complications which affect the vision.The measurement of cornea posterior elevation is an important way helping to find this change.Objective The aim of this study was to investigate the change of cornea posterior elevation after LASIK in myopic eyes with astigmatism and affecting factors.Methods A series case-observational study was adopted.One hundred and twenty-seven myopic eyes with astigmatism of 66 patients who received LASIK in 2008 May through 2010 January in Beijing Tongren Hospital were retrospectively analyzed to evaluate the change of cornea posterior elevation following the LASIK.The parameters related to cornea posterior elevation were measured and compared before and 3 months,6 months and 1 year after surgery,respectively,with Oculyzer anterial segment analysis system.Results The height values from posterior cornea highest point,the lowest point and central vertex central elevation zone were (12.20±3.39),(-19.02±7.38) and (1.05 ±3.25) μm respectively before LASIK and were (14.38±3.80),(-18.55±7.11),(2.83±4.81)μm in3 months and (13.99±3.38),(-17.57±6.54),(2.45±4.61) μm in 6 months after LASIK.They were (14.40±3.85),(-17.76±6.00),(2.16±5.00) μm in 1 year after surgery.Significant increases were found in the vertex height and central elevation after LASIK compared with before surgery(highest pointq=6.813,5.594,6.875,all at P＜0.001.central vertex:q=4.488,P=0.002;q =3.530,P=0.013 ;q =2.799,P =0.047).However,no significant difference was seen in various time points after LASIK (P＞0.05).A positive correlation was obtained between the height value of the posterior cornea central vertex with the spherical equivalent (SE),maximum cutting depth or cutting proportion 1 year after LASIK (r =0.295,0.297,0.295,all at P=0.001),and there was a negative correlation between it with residual stroma (r=-0.208,P=0.019).The intraocular pressure (IOP) measured with noncontact tonometry (NCT) was (14.24±3.33) mmHg before LASIK,and those of 3 months,6 months and 1 year were (8.42± 1.90),(8.61 ± 1.64) and (8.76± 1.64)mmHg after LASIK,showing a significant lowing in IOP after LASIK in comparison with before LASIK (q =29.851,28.317,26.337,all at P＜0.001).But no significant change was found in the different time points after LASIK (P＞0.05).There was significant difference in the IOP corrected by Ehlers after LASIK (P＞0.05).The IOP before LASIK had positive correlation with the central elevation of posterior cornea surface 1 year after LASIK(r=0.258,P =0.003).Conclusions The cornea posterior elevation increases slightly early stage after LASIK but retains stable level with lapse of time.The refraction diopter before LASIK is the main factor affecting the posterior corneal shape.To reduce the risk of corneal ectasia,more attention should be paid to the reserving of appropriate corneal residual stroma and smallest degree of eccentricity during the ablation procedure.

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
