ve To understand the levels of trace elements in hair of patients with hypertension disease and coronary heart disease. Methods The contents of zinc, copper, manganese and iron in hair were determined among 45 patients with hypertension disease, 36 patients with coronary heart disease and 40 healthy controls by flame-atomic absorption spectrophotometry respectively. Results The contents of zinc and the ratio of the contents of zinc vs the contents of copper in hair of patient with hypertension disease and coronary heart disease showed significantly higher levels compared with those of healthy controls (P

Objective To explore the prognostic effect of fluid-attenuated inversion recovery imaging vascular hyperintensity (FVH)on intravenous thrombolysis of acute ischemic stroke.Methods We retrospectively reviewed the clinical and imaging data of intravenous thrombolytic patients with acute anterior circulation infarction admitted from May 2009 to December 2013.The presence of FVH was evaluated,and its associations with reperfusion and clinical outcome after thrombolysis were assessed.Results Ninety-three patients were analyzed.FVH was detectable in 55 (59.1％) cases.Patients with FVH had higher NIHSS scores (11.8 ± 6.0 vs 7.2 ± 4.5,P ＜ 0.01),larger initial DWI lesions (5.5 ml vs 2.0 ml,Z =-3.030,P=0.002) and perfusion lesions (42.0 ml vs 3.0 ml,Z=-6.104,P =0.005),compared with those without FVH.The history of hyperlipidemia (OR =0.264,95％ CI 0.07-0.90,P =0.048) and proximal large vessel occlusion(OR =48.874,95％ CI 11.6-205.924,P ＜ 0.01) were independently associated with the presence of FVH.The presence of FVH independently predicted the poor neurological outcome at 3 months (OR =4.143,95 ％ CI 1.440-11.919,P =0.008).However,early reperfusion was associated with favorable outcome in patients with FVH after intravenous thrombolysis (OR =8.500,95％ CI 1.964-36.790,P =0.004).Conclusions The presence of FVH is associated with proximal large vessel occlusion,which predicts poor outcome in patients with intravenous thrombolysis.However,early reperfusion among patients with FVH can improve the outcome.

Objective To explore the related factors to influence the curative effect of focused ultrasound treatment for non neoplastic epithelial disorders of vulva. Methods A total of 382 patients with non neoplastic epithelial disorders of vulva were included in this study and treated by focused ultrasound. During and after the treatment, the symptoms and physical signs of the subjects were observed, and the efficacy was evaluated. We analyzed the relation between pathologic type, age, course, area, or itch degree and curative effect. Results Symptoms of all patients were relieved, and appearance and color of the vulva became normal after the ultrasound treatment, with a total effective rate of 99.74%. The cure ratios of patients with different pathologic types, ages, courses, areas, and itch degrees were significantly different (χ2=9.58, P<0.01; χ2=22.385, P<0.01; χ2=32.260, P<0.01; χ2=57.99,P<0.01; χ2=42.13,P<0.01, respectively). Conclusion Focused ultrasound treatment is safe and effective for the nonneoplastic epithelial disorders of the vulva and the efficacy is associated with the pathologic type, age, course, area, and itch degree.

Objective To observe the effects of an enriched environment (EE) on cognitive functioning and the synaptic plasticity of mice modeling post-stroke cognitive impairment (PSCI) and explore the possible mechanisms involved.Methods Mice modeling PSCI and sham-operated mice were randomly divided into 3 groups:sham-operated mice in a standard environment (the Sham+SE group),PSCI mice in a standard environment (the PSCI+SE group) and PSCI mice in an enriched environment (the PSCI+EE group).The cognitive functioning of all of the mice was quantified using a Morris water maze and their hippocampal long-term potentiation (LTP) was recorded using an electrophysiological method.The level of synaptophysin was detected using Western blotting.Synaptic ultrastructure in the hippocampus was imaged using electron microscopy.Results Compared with the Sham +SE group,the PSCI+SE group showed significantly poorer water maze performance and failed induction of contralateral LTP.Their average level of synaptophysin was significantly lower,and significant adverse changes in the synaptic ultrastructure of the hippocampus were observed,including a decreased number of synapses.The average width of the synaptic cleft,postsynaptic density and the interface curvature of the synapses were all less desirable.All of the measurements of the PSCI+EE group improved significantly compared to those of the PSCI+SE group,but were still significantly poorer than those of the Sham+SE group.Conclusions An enhanced environment can improve the cognitive functioning of mice modelling PSCI.It may be that an EE can improve synaptic plasticity in the hippocampus contralateral to the stroke.

The means of OD value measurement and plate counting were used to choose the bacterial growth stimulants. Among the 120 substances sorted to 13 kinds (the trace elements, REE, carbohydrate, amino acids and amino acids derivatives, vitamins, nucleosides, plant hormones, animal hormones, plant and animal extracts, Echlonia Kurome Okum water extract and yeast extract), Echlonia Kurome Okum water extract and yeast extract were found to stimulate the growth of Escherichia coli significantly.

Objective To investigate the perinatal outcome of fetus with increased nuchal translucency (NT) at first trimester.Methods The thickness of NT above 95th percentile of the fetuses with same crown-rump length (CRL) was set as the criteria of increased NT.The outcomes of fetuses with increased NT during early pregnancy from Jan.2008 to Dec.2009 in Guangzhou Women and Children's Medical Center were followed up.The information of ultrasound at second trimester,pregnant complications and delivery outcome were collected.All infants were followed up for 3 months after birth and were divided into four groups according to their different thickness of NT.The relationship between NT thickness and perinatal outcome were analyzed with single factor analysis of variance and multiple comparison method.Results Among the 178 cases we followed up,there were 2 spontaneous fetal losses and 19 terminations whose reasons were Down syndrome (n=6),severe a thalassemia (n =5),fetal malformations (n =7) and social factor (n =1).Among the 157newborns delivered,one was found with congenital heart disease.The rate of abnormal infants was 11.8％ (21/178) and the detection rate of abnormal infants was 9 5.2％ (20/21).Healthy living rate of fetus with NT thickness between 95th percentile and 2.9 mm was 96.1％ (122/127); 82.4％ (28/34) for those with NT thickness between 3.0 mm and 3.9 mm; and 35.3％ (6/17) when NT≥ 4.0 mm.Conclusions Increased NT might have close relationship with poor pregnant outcome.The thicker the NT,the lower the healthy living rate of the fetus.The pregnant outcome is very poor if NT≤4.0 mm.

Objective To investigate the expression of c-jun in precancerous lesion and squamous cell carcinoma tissues of hamster buckle pouch mucosa.Methods The models of premalignant and malignant lesions were established in hamster buckle pouch mucosa induced with DMBA.The expressions of c-jun in 23 oral normal mucosa, 22 abnormal epithelial hyperplasia and 29 oral squamous cell carcinoma (OSCC) were measured with immunohistochemical SABC method.Results c-jun mainly expressed in basal cells and prickle cells in normal mucosa,simple and abnormal epithelial hyperplasia,its positive expression was in nucleus.c-jun expressed mainly in various layer cells of OSCC,its positive expression was in nucleus and cytoplasm.There were significant differences of positive expression rate between various groups(?2=13.71,P
