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 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 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 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.

Objective To explore the effects of different courses of antenatal dexamethasone on brain development of premature SD rats. Methods The pregnant rats were randomly assigned to 3 groups: 3-dose dexamethasone (group 1), 1-dose dexamethasone group (group 2) and control group. The treated were sacrificed on 19 days of gestation, body and whole brain weight of the offspring rats were measured. Meanwhile the expression o{ neuron specific enolase (NSE) in brains of offspring rats was detected by immunohistochemical staining. The histological structures of baby rat brain were observed under transmission electron microscope. The differences among the three groups were analyzed by ANOVA. Results (1) The body and whole brain weight, the brain and body weight ratio were (1.543±0.052) g, (88.80±7.12) mg, and (5.75±0.38)% in group 1 and (1.584±0.035) g,(98.21±3.71) mg, and (6.20±0.26)% in group 2, both were lower than the control group [(1.696±0.076) g, (111.53±6.29) mg, (6.59±0.48)%], (P<0.01 or P<0.05, respectively). (2) The expression of NSE in cortex in group 1 and 2 were lower than that in control group (0.223±0.054, 0.381±0.041 vs 0.590±0.064) (P<0.01). The expression of NSE in hippocampi in group 1 and 2 were also lower than that in the control group (0.192±0.054, 0.359 ±0.046 vs 0.529±0.068) (P<0.01). (3) Disconnection of nuclei membrane, vacuolization in mitochondria, loss of nueleolus, and disconnection of neurofilaments were observed in the ultrastructure of baby rat brain tissue in both group 1 and 2. Conclusions Antenantal administration of dexamethasone can cause impairment of brain development in premature offspring rats and this might be related to the times of dexamethasone administered.

Objective To investigate the effect of venous indwelling needle on peripherally inserted central catheterization (PICC).Method Seventy-eight critical patients underwent PICC through external jugular vein using venous indwelling needle at the emergency treatment.Result The success rate for one-time puncturing was 97.4%,without any complications.Conclusion PICC through external jugular vein using venous indwelling needle is advantageous for its safety,fewer complications and longer indwelling duration.

Objective To investigate the correlation and clinical diagnosis significance between ultrasound elastography and the distribution of myofibroblast in breast tumor.To assess the value of ultrasonic elastography and myofibroblast in the diagnosis of breast cancers.MethodsThree-hundred and fifteen patients recruited from May 2009 to November 2010 were divided into benign group and malignant group according to postoperative pathological diagnosis results considered as gold standard.The clinical value of the score of ultrasonic elastography was evaluated.The expression levels of CD34 and α-SMA protein in breast tissues were examined by immunohistochemistry.ResultsThe difference was statistically significant for the expression level of CD34 and α-SMA between malignant breast tumor patients compared with benign ( P ＜0.05).The expression level of CD34 was lower,but α-SMA was higher in the patients of breast cancer compared with benign tumor.However,the expression level of CD34 and α-SMA was just the opposite in the patients of benign tumor.The expression level of CD34 was the negative correlation with the elastography score ( P ＜0.05) in the breast tumor,but α SMA just the opposite situation.Conclusions The score of ultrasound elastography can represent MFS distribution characteristics in breast tumors in the result that α-SMA +/CD34- can determine the existence of myofibroblast.

Objective To investigate changes of striatal DAT following hypoxic ischemic (HI)brain injury in newborn piglets using 11C-N-2-carbomethoxy-3-(4-fluorophenyl)-tropane (CFT) PET/CT,and to evaluate the value of 11C-CFT PET/CT in brain injury.Methods Newborn piglets with HI brain injury (n =20) were taken as a model group,and five piglets were used as a control group.Radioligand 11CCFT (55.5-74.0 MBq) was injected through the jugular vein,and PET/CT imaging was performed to observe the changes of striatal DAT in newborn piglets.The ST/occipital lobe (OC) ratio was calculated.Model group was divided into 0-6 h,20-24 h,44-48 h and 68-72 h sub-groups after HI in accordance with the imaging time.The piglets were sacrificed immediately after 11C-CFT PET/CT scanning,and then the brains were removed for pathological analysis.Data analysis was performed with one-way analysis of variance and Pearson linear correlation analysis.Results After intravenous injection of 11C-CFT,the radioactivity accumulation in cortical,striatum,and cerebellum was shown clearly in the control and model groups.The radioactivity accumulation was lower in the white matter.The radioactivity in cortical and cerebellum exhibited decreased with time,while the striatum was still clear.After HI,the ST/OC activity ratio in the striatum was initially increased,and the ratio of 0-6 h group (1.34 ± 0.04) was statistically significant compared with that of thecontrol group (1.18 ± 0.06 ; F =4.658,P ＜ 0.05),followed by a gradual decrease.ST/OC ratios of other HI subgroups were 1.27 ±0.01,1.27 ±0.10 and 1.18 ±0.05,respectively.There was a positive correlation between the number of DAT positive neurons ((13 ± 3),(13 ± 4),(8 ±3) and (4 ±4)/high power field) and 11C-CFT ST/OC activity ratios (r =0.844,P ＜0.05).Conclusion 11C-CFT PET/CT study can accurately reflect the changes of DAT in the striatum,and the amount of DAT is related to the severity of the ischemic insult in a newborn piglet model of HI.

Objective To explore the vitamin D nutritional status of urban residents in Jinan,in order to provide the basis for the prevention and treatment of chronic diseases associated with vitamin D insufficiency.Methods 1478 cases aged 30-90 years,including 602 men (59.8± 13.0) years on average and 876 women (57.4±12.9) years on average were selected by a stratified random sampling from 3 community medical care institutions in Jinan.Subjects were divided into six groups according to the 10-year interval.Serum 25-hydroxyvitamin D [25(OH) D] level was measured by enzyme-linked immunosorbent assay (ELISA).Serum [25(OH) D] level ≥ 75 nmol/L was defined as vitamin D sufficient,(50.0 ～ 74.9) nmol/L as vitamin D critical value,25.0 ～ 49.9 nmol/L as vitamin D insufficiency,＜ 25 nmol/L as vitamin D deficiency.All data processing and statistical analysis were finished by SPSS 13.0.Results The average level of [25 (OH) D] was 58.60 nmol/L in males [95％ CI:56.7-60.5 nmol/L] and 54.17 nmol/L in females [95％ CI:52.8-55.8 nmol/L],which were less than 75 nmol/L.The average level of [[25(OH) D] was 49.1nmol/L in females aged 70-79 years (95％CI:45.7～52.5 nmol/L),41.7 nmol/L in females aged 80-90 years (95％CI:38.2 ～46.7 nmol/L),which were less than 50 nmol/L.The percentage of cases with vitamin D deficiency,insufficiency,critical value,and sufficiency was 5.6％,33.4％,36.5％,24.4％ in males,and 6.5％,42.9％,32.6％,18.1％ in female respectively.The incidence of vitamin D deficiency and insufficiency was increased with ageing (male:x2 =33.68 P＜0.01,female:x2 =55.7,P＜0.001).The percentage of vitamin D deficiency and insufficiency was more in females than in males (60-69 years old:x2=9.387,P＜0.05,80-90 years old:x2=8.896,P＜0.05).The [25 (OH) D] level was lowest in winter (48.8 nmol/L,95％CI:46.8～50.9 nmol/L) and highest in autumn (60.2 nmol/L,95％ CI:58.0～62.3 nmol/L).The incidence of vitamin D deficiency and insufficiency was highest in winter (x2 =18.364,P＜0.05).Conclusions Vitamin D deficiency and insufficiency are widely prevalent in urban residents,which is more severe in the elderly and females.Serum [25(OH) D] level is related to season,and the vitamin D deficiency and insufficiency are severe in winter.
