ObjectiveTo explore the effect of various forms of psychological intervention on psychological stress,mental state and treatment process of out- patients. Methods 198 outpatients from February 2010 to July 2011 were randomly divided into the observation group and the control group with 99 cases in each group.The control group received conventional treatment and care.The observation group was given multiple forms of psychological intervention on the basis of conventional treatment and care.Both groups were taken with Zung Anxiety Rating Scale (SAS)and the Hamilton Anxiety Scale(HAMA)to measure the psychological stress and the degree of anxiety before and after treatment.The total efficiencies of various disorders for the two groups before and after the diagnosis and treatment were compared. ResultsThere were no significant differences in SAS score and HAMA scores before psychological intervention.After the intervention,the SAS score and HAMA score in the control group were significantly higher than the observation group.The total effective rate after a course of treatment in the observation group was 90.6％.The total efficiency in the control group was 78.8％,which was significantly lower than that of the observation group. ConclusionsThe multiple forms of psychological intervention can reduce the mental stress,ease the patients' emotional state and improve the patients' therapy effect at the same period for out-patients.

Objective To study the chemical constituents of the whole plant of Pholidota yunnanensis and to examine the inhibitory effects of the isolated compounds on nitric oxide(NO) production in activated rat macrophage-like cell line(RAW 264.7).Methods Various chromatographic techniques were used to separate and purify the constituents,and their structures were elucidated on the basis of spectroscopic analysis. The inhibitory effects of these compounds on NO production in RAW 264.7 cells of rats activated by lipopolysaccharide(LPS) and interferon-?(IFN-?) were tested in vitro by microplate ultraviolet-colorimetric method.Results Seven compounds were isolated and identified as trans-3,3′,5-trihydroxy-2′-methoxystilbene(Ⅰ),cis-3,3′-dihydroxy-5-methoxystilbene(Ⅱ),trans-3,3′, 5-trihydroxystilbene(Ⅲ),3,3′-dihydroxy-5-methoxybibenzyl(batatasin-Ⅲ,Ⅳ),3,4′-dihydroxy-3′,5-dimethoxybibenzyl(gigantol,Ⅴ),3,3′,5-trihydroxybibenzyl(Ⅵ),2,7-dihydroxy-4-methoxy-9,10-dihydrophenanthrene(coelonin,Ⅶ).Conclusion Compounds Ⅱ,Ⅳ,and Ⅵ show favorable inhibitory effects on NO production,compounds Ⅰ and Ⅱ are new compounds,and compounds Ⅲ-Ⅶ are isolated from this genus for the first time.

Objective To investigate the effects of Pravastatin on serum oxidative modified LDL (ox-LDL), tumor growth factor ?1 (TGF-?1), vascular cell adhesion molecule-1 (VCAM-1) and lipid levels in patients with acute cerebral infarction(ACI).Methods 114 cases with ACI were randomly divided into two therapy groups: (1) 56 cases were given Pravastatin combined with Aspirin;(2) 58 cases were treated with Aspirin only. The serum levels of ox-LDL, TGF-?1, VCAM-1 and lipid were detected 72 h after the onset of the disease and 3 months following the treatment. Meanwhile, the same were detected in the control group (50 healthy people). Results Within 72 h, the serum levels of ox-LDL, VCAM-1, cholesterol and LDL were higher in patients with ACI than those in control group(all P

Objective To observe the initial therapy outcomes of Valproic acid for childhood absence epilepsy (CAE),and to assess its therapeutic reaction and short-term prognosis,and to investigate the risk factors for initial therapy failure.Methods From January 2010 to December 2015,absence seizures as key words were used to search CAE in the video-electroencephalogram(VEEG) database of Children's Hospital Affiliated to Nanjing Medical University.Sixty-seven children fulfilled the CAE diagnosis criteria of International League Against Epilepsy in 1989.These patients were separated into 2 groups based on the therapy outcome after 6 months,including seizure control failure group and seizure control group.The patients' clinical characteristics and VEEG characteristics were reviewed.The gender,age of seizure onset,a family history of epilepsy or febrile seizures (FS),consistent with 2005 Panayiotopoulos diagnostic criteria,and VEEG findings were analyzed to evaluate the predictive ability of independent variables and the relationship between these features and treatment outcomes by using a stepwise multivariate Logistic regression model.Results The age at seizure onset was (5.89 ± 2.91) years old,and follow up duration was 6 months.Approximately 23 cases (34.3％) of CAE patients had poor response.No statistical correlation was made for gender,age at onset,the occurrence of generalized tonic clonic seizures,and family history of FS or epilepsy between 2 groups (all P ＞0.05).Compared with seizure control group,patients of the seizure control failure group had significantly higher rates of focal epileptic discharge (87.0％ vs.6.8％),higher rates of intermittent photic stimulation (IPS) induced seizures (52.2％ vs.6.8 ％),fewer rates of occipital intermittent delta activity (8.7 ％ vs.77.3 ％),and fewer rates of patients met the new diagnostic criteria proposed by Panayiotopoulos in 2005 (8.7％ vs.88.6％) (all P ＜ 0.001).The presence of occipital intermittent rhythmic delta activity during wake stage and the interictal focal epileptiform discharges on VEEG during sleep stage were significantly associated with the therapy outcomes in a multivariable Logistic regression analysis (OR =133.714,P ＜ 0.05;OR =0.068,P ＜ 0.05).Conclusions The presence of focal epileptiform discharges,and a typical absence induced by IPS are important factors for first-drug treatment failures with CAE,and conversely the occipital intermittent rhythmic delta activities have a good efficacy.There is no statistical correlation between clinical characteristics and treatment outcomes.
