Objective:To evaluate the security, efficacy and side effects of E_2 transdermal patch (Fem-7) in the treatment of menopausal syndrome. Methods:A total of 60 cases with menopausal syndrome (blood serum FSH >30 U/L,E_2 <109.8 pmol/L) were randomly divided into treatment group ( Fem-7 group) and control group (estrodiol valerate (E_2V) group) for 12 weeks treatment. Fem-7 group changed patch every 7 days and took the 2 mg medroxyprogesterone (MPA) every day. While the E_2V group took the 2 mg MPA and 1.5 mg E_2 V every day. Serum E_2, FSH, lipoprotein and coagulation function were evaluated at baseline and at the 12th week of the treatment. In addition, menopausal symptoms and some other index of security and side effects were also observed. Results:Kupperman indix in both groups was decreased and the mean value of E_2 was increased obviously. Hepatic function, renal function, coagulation function and blood glucose were no obvious change. Lipoproteina was descended markedly in Fem-7 group. Other index of security in both groups was no obvious change. Conclusions:Fem-7 patch is secure and valid for relieving symptom of menopause, especially for the women who is not sutable for oral medication.

International Eye Science 2016;16(7):1322-1324
AIM: To observe the therapeutic effect and safety of improved extra panretinal photocoagulation ( E - PRP) in the treatment of high risk proliferative diabetic retinopathy (hsPDR).
METHODS: A total of 88 consecutive cases (102 eyes) with hsPDR were diagnosed by fundus fluorescein angiography(FFA) from February 2011 to December 2014 in our hospital . Fifty two eyes had been treated by improved E - PRP with 532nm frequency - doubled laser. Fifty eyes had been treated by standard PRP. All cases were checked by FFA and fundus photocoagulation every 3mo. Patients with persisting neovascularization or non perfusion area were treated with laser again. All cases were followed up 6-36mo.
RESULTS: The postoperative visual acuity had no statistical difference between two groups ( P > 0. 05). In improved E - PRP group, retinal non perfusion area and neovascularization disappeared in 35 eyes ( 67%). Effective rate was 88%. Six eyes (12%) underwent pars plana vitrectomy because of vitreous hemorrhage, fiberosis and stretched retinal detachment. In standard PRP group, retinal nonperfusion area and neovascularization disappeared in 23 eyes ( 46%). Effective rate was 66%. Seventeen eyes(34%) underwent pars plana vitrectomy because of anterior retina bleeding or vitreous hemorrhage. The rate of neovascularization disappeared and effective rate had statistical difference between two groups (P<0. 05).
CONCLUSION: It is a safe and effective methods to treat hsPDR by improved E-PRP and it was more effective than traditional PRP.

Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.

Neural cell adhesion molecule (NCAM) is a glycoprotein expressing on the surface of neurons, glial cells, bone cells and natural killer cells. NCAM plays an important role in the process of cell - cell adhesion and cell migration, and is also a model protein to study polysialic acid. In this paper, NCAM gene from mouse mammary gland cells (NMuMG) was cloned into eukaryotic expression vectors pcDNA3.1(+) and transfected into mutant Chinese hamster ovary cells ldlD-14. The stable transfection over-expressing NCAM was obtained through the G418 selection and confirmed by Western blotting. Due to unique characters of ldlD-14 cells, carbohydrate chain of NCAM molecule can be easily manipulated with or without adding galactose in the serum free medium, and this modification can provide the basis for further studies on the effect of glycosylation on NCAM molecular function.

Objective To assess the left ventricular(LV) volumes and function acquired by realtime (RT) three-dimensional echocardiography (3DE) versus magnetic resonance imaging (MRI) in elderly patients.Methods A total of 31 patients aged≥60 years [mean (72.1±6.6) years] with various cardiovascular diseases were evaluated by MRI versus RT-3DE on the same day.RT-3DE was performed with a Philips iE-33 echocardiographic system,and LV volumes and function were analyzed with the assistance of TomTec software.The results of LV volumes and function obtained by manual tracing were compared with Signa 1.5-T MRI data.The acquisition of RT-3DE datasets was feasible in all 31 patients.Results The average MRI-detected LV end diastolic volume (LVEDV) was (139.1 ±40.8) ml,LV end systolic volume (LVESV) was (77.8±41.7)ml,LV ejection fraction (LVEF) was (47.9±14.3)%.The average RT-3DE-detected LVEDV was (119.5±37.7) ml,LVESV was (65.5±36.1) ml,LVEF was (47.9± 14.3)%.Compared with MRI values,LVEDV was underestimated by RT-3DE (P<0.01,r=0.79,y=0.73 x+17.8,SEE=23.5 ml),with a mean difference of (-19.6±25.6)ml; LVESV was also underestimated by RT-3DE (P<0.01,r=0.89,y =0.77 x+ 5.6,SEE=16.8 ml),with a mean difference of(-12.3± 19.1)ml.Ejection fraction determined by MRI was the same as that by RT-3DE (P>0.05,r=0.91,y=0.75 x+ 13,SEE=5.61%),with a mean difference of (1.1±7.4) %.There was good interobserver reproducibility in LV volume detected by RT-3D.Conclusions Compared with MRI,RT-3DE has more accuracy and repeatability in assessment of LV volume and ejection fraction in elderly patients.

Visfatin was recently reported as an adipokine and was found to exert insulin-mimicking effects.The results showed that the expression of visfatin parallelled with obesity and insulin resistance in long term high fat chow-fed rats.The expression of visfatin mRNA was decreased and the insulin resistance improved after rennin-angiotensin system was blocked.Visfatin may play an important role in the pathogenesis of insulin resistance.

Objective: In this paper the pharmacodynamical mechanism of Heat Asthma Formula(HAF)(Herba Ephedrae, Rhizoma pinelliae, Flos Lonicerae, etc) in the treatment of bronchial asthma was discussed. Methods: By means of the radio labelled aglycone, applying phlogistic medium TXB2, ? receptor on bronchus and cyclic nucleotide (cAMP/cGMP) in lung tissue used as observed targets. Results: The results showed HAF could inhibit the release of phlogistic medium TXB2, improve the conjugate rate of ? receptor, adjust the proportion between cAMP and cGMP. Conclusion: The treatment on bronchial asthma of “Heat Asthma Formula” was perhaps concerned with above mentioned contents.

Objectives: To investigate the effects of adhesion and proliferation of bone mesenchymal stem cells (BMSCs) in the surface of lactic acid/glycolic acid/asparagic acid-co-polyethylene glycol PLGA-[ASP-PEG] tri-block polymer scaffolds, try to find a new biomaterial to induce seed cells in vitro for bone tissue engineering. Methods: Modified PLGA with polyethylene glycol (PEG) and asparagic acid (ASP) that has many ligands, and synthesis PLGA-[ASP-PEG] polymer material. BMSCs were cultured in PLGA-[ASP-PEG] polymer material and PLGA used as control group. Through precipitation method, MTT assay and total cellular protein detection to test the adhersion and proliferation of BMSCs. Scanning electron microscope is used to observe cells appearance. Results: BMSCs on the surface of PLGA-[ASP-PEG] polymer scaffolds are adherention to the culture flask, the number of cells is much higher than PLGA’s. The precipitation method suggest that adhesion and proliferation of BMSCs on the surface of PLGA-[ASP-PEG] is much higher than the control group(P
