Objective To observe the effects of hormone replacement therapy (HRT) on endothelial function in menopausal women. Methods A total of 30 menopausal women were treated with 2.5 mg of Tibolone (Livial) daily. At the same time, 30 women with natural menopause without any treatment served as the control group. Endothelium-dependent (EDD), endothelium-independent (NID) vasodilatation function, and estradiol (E2) were examined by the non-invasive high-resolution ultrasonography before the treatment and at 12th, 24th, 36th and 48th week of treatment, respectively. Results After hormone treatment, E2 increased significantly and EDD was improved significantly (P<0.05), and E2 was positively related with EDD (r=0.8092, P<0.001). No change of EDD was observed in the control group whereas a significant increase was observed in the treatment group. Conclusion Endothelium-dependent vasodilatation dysfunction is prominent in menopausal women. Tibolone can help improve the condition.

Objective To assess the effects of tibolone treatment on the hemodynamic changes of the ophthalmic artery(OA) and internal carotid artery(ICA) as sonographic markers of atherosclerosis in menopausal women.Methods A total of 30 menopausal women were treated with 2.5mg of tibolone(Livial) daily as treatment group.At the same time,30 women with natural menopause who were not given any treatment served as control group.Noninvasive measurements of the resistance index(RI) and peak systolic blood flow velocity of ICA and OA were made with ultrasound before the treatment and at 3rd,6th,9th and 12th month of treatment,respectively.Results RI of ICA and OA decreased significantly after tibolone treatment(P

Asthma is a common disease in children. Adherence to inhaled glucocorticoid therapy directly affects the outcome of asthma. The article mainly reviews the adherence status, assessment method, patient barriers to non-adherence and intervention strategy,so as to provide references for clinical practices and scientific research of nursing staff.

Objective To study the relationship between PDD and the polymorphism of apolipoprotein E(apoE) gene,to inquire the etiological basis of PDD.Methods 11 Patients with PDD 40 patients with PD without dementtia and 52 unrelated controls were collected to detect the genotype of apoE gene by PCR－ RFLP. Results There was no difference in the apoE allele frequencies and genotype distribution in PDD group,PD without dementia group and control group(P >0.05). Conclusion There is no relationship between the polymorphism of apoEgene and the onset of PDD.The pathogenesis of PDD differs from that of AD.

BACKGROUND:Spermatogonial stem cells are a kind of adult stem cells, which have self-renewal and differentiation potential, and can be differentiated into specific cells in vitro, suggesting that the spermatogonial stem cells may be possibly differentiated into osteoblasts. But the related research has not been reported. OBJECTIVE:To observe the biological characterization and osteogenic process of mouse spermatogonial stem cells cultured in vitro. METHODS:Spermatogonial stem cells were obtained from the testicle of mice aged 15-20 days, and were cultured on the feeder layer from bone marrow stroma cells in vitro. When cultured for 3 days, the cells were cultured in the conditioned medium (experimental group) and basic medium (control group). The cells proliferation capability and osteogenic property were examined by phase-contrast microscope, alkaline phosphatase activity and type I col agen immunofluorescence staining. RESULTS AND CONCLUSION:Spermatogonial stem cells proliferated faster in the experiment group than in the control group. cells grew rapidly in colony-like shape in the conditioned medium at 3-6 days, the three-dimensional feeling enhanced, cellmass and clusters continued to increase in size, the extracellular matrix was increased in number and the cytoplasmic bridge was not obvious. After culture for 15 days, cells in the two groups were positive for alkaline phosphatase staining that the cytoplasmic membrane was dyed black. Under the fluorescent microscope, green fluorescence was visible in the experimental group, suggesting the cells in the experimental group was positive for type I col agen, but negative in the control group, which is similar with the biological characteristics of osteoblasts. These findings indicate that spermatogonial stem cells possess the osteogenic capability under induction conditions, which are expected to provide seed cells for bone tissue engineering.

AIM:To develop a method for determining cholic acid by HPLC-ELSD and GC was applied to determing muscone;in Jawei Xihuang Soft Capsule(Calculus Bovis,Moschus,Venenum Bufonis,Olibanum,Myrrha).METHODS:AC_(18) column(Kromasil C_(18),5 μm,4.6 mm×250 mm)was used as stationary phase,the mobile phase was methanol-0.01% glacial acetic acid(73:21)at a flow rate of 1.0 mL/min.The parameters of ELSD were set as follows:evaporation temperature was 40℃,carrier gas(N_2)pressure was 200 kPa.The GC system consisted of DB-1 capillary column(30 m×0.32 mm×0.25 μm)and FID as the detector.The programmed temperature-GC and internal standard method were employed to determine the content of muscone.RESULTS:The linear ranges of cholic acid and muscone were in the range of 45.2 ng-904 ng and 0.05 mg/mL-0.5 mg/mL respectively.The average recoveries were 99.06% and 99.40% with RSD of 1.56% and 0.95% respectively.CONCLUSION:The method is convenient and accurate,and it can be used for the quality evaluation of Jawei Xihuang Soft Capsule.

Objective To investigate effect of Bailing Capsule combined with Xihuangwan in stage III breast cancer patients of ER, MMP-9, tumor markers and estrogen.Methods 76 Patients with stage III breast cancer were selected and divided into control group anf experiment group.Control group were treated by clinical routine method.Experiment group were treated on the base of the control group with Bailing Capsule combined with Xihuangwan.The ER, MMP-9, tumor markers, estrogen, survival time and quality of life were observed and compared.ResuIts Compared with control group, the survival period of the experiment group were longer(P<0.05),the quality of life score were higher(P<0.05),the ER, MMP-9, E2, E1 level and the serum levels of CA15-3, CA125 and CEA were lower(P<0.05).ConcIusion Bailing capsule combined with Xihuang Pill can effectively reduce stage III breast cancer tumor marker levels, decrease the ER, the expression of MMP-9 and estrogen level and prolong survival time, improve the quality of life, has the vital significance to the clinical therapy for stage III breast cancer.
