Objective:To investigate the relationship between FA,ET-1,Hcy and VEGF in patients with pregnancy induced hypertension.Methods:Selected 80 cases of patients with pregnancy induced hypertension who were treated in our hospital from January 2013 to September 2016,divided into A group (40 cases),and preeclampsia and preeclampsia B group (40 cases),60 cases of normal late pregnant women as C group,60 cases of normal non pregnant women as D group.The plasma levels of FA,ET-1,Hcy and VEGF in each group were detected,and the correlation analysis was performed.Results:The plasma levels of FA and VEGF of group B were lowest in the four groups (P＜0.05),the plasma ET-1 and Hcy levels of group B were highest (P＜0.05).The plasma FA and VEGF levels of women with pregnancy induce hypertension were lower than those of the healthy late pregnant women.The plasma ET-1 and Hcy levels were higher (P＜0.05).The multivariate logistic regression analysis showed that FA,ET-1,Hcy and VEGF levels were risk factors for pregnancy induce hypertension.Conclusion:The elevation of plasma Hcy level caused by FA deficiency in pregnancy might be related to the development of the disease and the incidence of pregnancy induced hypertension syndrome,VEGF might be an important factor in the occurrence and development of pregnancy induced hypertension syndrome.

Objective To investigate the efficacy and clinical effectiveness of the steroid therapy with the all body and local application on hyperthyroid Graves ophthalmopathy.Methods A total of 57 patients (106 eyes)suffering from hyperthyroid Graves ophthalmopathy who hospitalized in the Department of Ophthalmology of the Second Affiliated Hospital of Harbin Medical University from Mar 2008 to Oct 2011 were enrolled in the study.Of the 57 patients,there were 21 males and 36 females,aged 18 to 57(average 37.28 ± 11.63).The clinical course was from 1 month to 5 years(average 29.63 ± 15.36 months).Based on the patient's age,sex and condition,the 57 patients were randomly divided into steroid pulse therapy with all body group(group SPT,29 patients,54 eyes)and peribulbar injection of long-term steraid group(group PI,28 patients,52 eyes).The patients in group SPT were treated with 0.5-l.0 g methylprednisolone by intravenous infusion daily for 3 days,and then stopped for 7 days,the treatment was repeated once.But the total application dose of methylprednisolone was not overruned 5.0-20.0 g.After that,the patients were treated with oral prednisone 40 mg/d.The dose of prednisone was reduced gradually to 5 mg/d.The total course of group SPT was 3 months.The patients in the group PI were treated with triamcinolone acetonide in periorbital injection of 20 mg once every two weeks for 3 months.After one month treated,all patients were visited.The patients' body weights of two groups were measured before the treatment and after one month treated.The ocular signs of the patients including visual acuity,diplopia,intraocular pressure,exophthalmos and horizontal visual palpebral fissure width were observed before and after the treatment.Results In the group SPT,the average body weight [(62.83 ± 7.23)kg]after the treatment was higher than that before the treatment[(57.03 ±7.13)kg],and also higher than that of the group PI[(59.89 ± 10.67)kg,t =25.25,2.08,all P＜ 0.05]after the treatment.In the group SPT,the average intraocular pressures before and after the treatment were (13.46 ± 1.78)and (13.69 ± 1.41)mm Hg(1 nm Hg =0.133 kPa),respectively.In the group PI,the average intraocular pressures before and after the treatment were (13.52 ± 2.19) and (13.77 ± 2.03)mm Hg,respectively.There was no significant differences before and after the treatment in both gr0ups(P＞ 0.05).In the group SPT and PI,the average exophthalmos after the treatment[(18.63 ± 2.22) and (14.85 ± 2.61)mm]were lower than those before the treatment[(20.78 ± 2.24) and (20.60 ± 2.81)mm,t =9.97,29.68,all P＜ 0.05],respectively.After the treatment,the average exophthalmos in the group PI was significantly lower than that of the group SPT(t =7.79,P＜ 0.05).In the groups SPT and PI,the average averagepalpebral fissure width after the treatment[(15.00 ± 1.80) and (11.65 ± 2.45)mm]were lower than those before the treatment[(17.22 ± 1.89) and (17.44 ± 2.37)mm,t =22.74,91.24,all P ＜ 0.05].After treatment of the group PI,the average exophthalmos was significantly lower than that of the group SPT(t =8.01,P ＜ 0.05).Conclusion Compared with the steroid pulse therapy with all body,the peribullbar application of long-term hormone for hyperthyroid Graves ophthalmopathy is more effective,with lcss side effects and worthy of promotion.

Objective： To discover HER2/neu tyrosine kinase inhibitor through computer-aided drug design approach. Methods： The three-dimensional(3D) structure of HER2/neu and EGFR tyrosine kinase domain was modeled using MODERLAR software. To search database and pick up candidate compounds based 3D structure of HER2/neu tyrosine kinase domain. Inhibition of HER2/neu tyrosine kinase phosphorylation by the compounds was detected using Western blot analysis. Inhibition of cell proliferation was determined by MTT assay. Results： The amino acid identity and similarity between HER2/neu and EGFR kinase domain, insulin receptor kinase domain, FGFR1 kinase domain, Src kinase domain were compared. The identity was 35％ -41％ and the similarity was 52％ -55％ . The 3D structure of HER2/neu and EGFR was obtained by MODERLAR software. Through searching, screening and optimization, the authors found that ST2325 had significantly inhibitory effect on HER2/neu tyrosine kinase phosphorylation with IC50 of 6.6 μ mol/L. The inhibition of HER2/neu phosphorylation was selective and reversible. ST2325 inhibited cell proliferation of HER2/neu-overexpressing MDA-MB-453m1 preferentially compared with EGFR-overexpressing MDA- MB-468, The IC50 values were 29.05 and 60.4 μ mol/L. Conclusion： ST2325 which was discovered through structure-based approach had notable inhibitory effect on HER2/neu tyrosine kinase.

Male sterility affects human reproduction seriously. Modern medicine has not yet fully understood the reasons for abnormal sperm, so clinical treatment is mainly based on experience, but the effect is inaccurate. According to "kidney controls reproduction" and "chronic illness causes blood stasis" theory, Professor JIN Bao-fang treats abnormol speerm sterility by tonifying kidney and activating blood circulation to remove obstruction with modified Yangjing Decoction, which has achieved good efficacy.

The aqueous phase oxidation of gaseous elemental mercury (Hg(0)) by potassium persulfate (KPS) catalyzed by Ag(+) was investigated using a glass bubble column reactor. Concentration of gaseous mercury and potassium persulfate were measured by cold vapor atom absorption (CVAA) and ion chromatograph (IC), respectively. The effects of pH value, concentration of potassium persulfate and silver nitrate (SN), temperature, Hg(0) concentration in the reactor inlet and tertiary butanol (TBA), free radical scavenger, on the removal efficiency of Hg(0) were studied. The results showed that the removal efficiency of Hg(0) increased with increasing concentration of potassium persulfate and silver nitrate, while temperature and TBA were negatively effective. Furthermore, the removal efficiency of Hg(0) was much better in neutral solution than in both acidic and alkaline solution. But the influence of pH was almost eliminated by adding AgNO(3). High Hg(0) concentration has positive effect. The possible reaction mechanism of gaseous mercury was also discussed.

Clinically many patients with non-obstructive azoospermia cannot benefit from assisted reproductive technology for absence of spermatozoa. However, the achievement in the studies of spermatogonial stem cells has brought hope to this cohort. This article reviews the molecular mechanisms of the proliferation and differentiation of spermatogonial stem cells, in such aspects as related genes, growth factors, and so on.
