ObjectiveTo provide a brief scale of mood measurement with satisfactory reliability and validity.MethodsThe 40-item BFS was abbreviated to a short-vcrsioncd BFS by item analysis.282 adult participants were surveyed by the brief BFS and NEO-FFI while NEO-FFI was taken as a criterion instrument.Reliability and validity of brief BFS were examined.ResultsThe brief BFS had 18 items including six dimensions ( activity,cheer,calmness,indignation,stir and depression),and the cronbach's α were 0.87,0.75,0.85,0.86,0.84 and 0.86 respectively and the retest reliability( r value) were 0.67,0.57,0.61,0.62,0.75 and 0.69 respectively.All the key fit indices of confirmatory factor analysis (CFA) of brief BFS were above 0.90.Besides,NEO-FFI had significant correlation with brief BFS.ConclusionThe brief BFS has satisfactory reliability and validity.

Objective To investigate the expression of interleukin 18 (IL-18) in liver tissues of patients with chronic hepatitis B (CHB) and its clinical significance.Methods Totally 172 CHB patients admitted in the Second Affiliated Hospital of Anhui Medical University from January 2012 to December 2012 were enrolled.The tissue specimens were obtained by liver biopsy from all patients,and 22 normal liver specimens were also collected as controls.Liver function,serum markers of HBV and HBV DNA load were measured and liver inflammation grades and fibrosis stages were assessed.Immunohistochemical method was used to detect the expression of IL-18 in liver tissues.Spearman rank correlation was used to analyze the correlations between IL-18 expression and the above indicators.Results IL-18 was mainly expressed in cytoplasm of liver cells.It was positive or strong positive in liver cells of healthy people,but weakly positive in liver cells of CHB patients.The difference of IL-18 expression between CHB patients and healthy people was of statistical significance (x2 =42.124,P ＜ 0.05).In CHB patients,the expression of IL-18 was gradually enhanced with the increasing of ALT,inflammation grades and fibrosis stages (r =0.182,0.173 and 0.068,P ＜0.05),but it was not correlated with HBV DNA load and HBeAg (r =-0.05 and 0.041,P ＞0.05).Conclusion In CHB patients,the expression of IL-18 may be involved in liver injury and fibrosis formation.

Objective To investigate the effect of ischemic post-conditioning (IPO) on the level of Heme oxygenase-1 (HO-1) in acute ischemia - reperfusion (I/R) injury of lung in order to illuminate its protective mechanism.Methods Forty-eight adult SD rats were randomly divided (random number) into 6groups ( n =8 each):sham operation group ( S group) ; I/R group in which the hilum of left lung was clamped for 45 min followed by 105 min reperfusion; IPO group in which left lung hilum was clamped for 45min and post - conditioned by alternation of 30 s reperfusion with 30 s re-occlusion for three times before perfect perfusion for 102 min; Hemin (HM) + I/R group; ZnPPⅨ (zinc protoporphyrin Ⅸ) + IPO group and HM + S group.Arterial partial pressure of oxygen ( PaO2 ) and malondialdehyde (MDA) content in blood serum were assayed.The left lung was removed for determination of wet/dry (W/D) lung weight ratio and level of HO-1 protein was detected by immunohistochemical technique and pathohistological changes were observed under light microscopic examination. Comparisons among multiple groups were studied by using one-way analysis of variance (ANOVA). Statistical comparisons within groups were analyzed by using paired t -test.Results The level of HO-1 in lung tissue was significantly increased in the I/R group compared with the S group and the HM + S group (P ＜0.01,P ＜0.05).Compared to the I/R group,the IPO and the HM + I/R groups had significant higher level of HO-1 ( P ＜ 0.05,P ＜ 0.01 ).The PaO2 was significantly lower in all experimental groups than that in the S group (90 ± 11 ) mmHg.However,the values of PaO2 in the IPO and the HM + I/R groups were higher than that in the I/R group (P ＜ 0.01 ).In addition to severe lung tissue damage evidenced by pathohistological changes,the lung wet/dry (W/D) weight ratio and MDA level in blood serum were significantly higher in the I/R group than those in the S group (P ＜0.01 ),whereas the lung damage was attenuated either by IPO or by HM pretreatment (P ＜ 0.05,IPO or HM + I/R vs.I/R).Conclusions IPO can attenuate the lung ischemia - reperfusion injury through upregulating the level of HO-1 protein and inhibiting lipid peroxidation injury.

Objective　To investigate the relationship betwee n tricuspid insufficiency (TI) and the function of the right ventricle, degree o f pulmonary vascular pathological change in patients with rheumatic heart diseas e so as to provide the indication of operation for treating TI. Methods 　41 cases of rheumatic heart disease with TI accompanying with bicuspid pathological changes were reviewed. Correlation analysis was done between the s everity of TI and the right ventricular size(RVS), pulmonary artery pressure(PAP ), pulmonary artery resistance(PAR) etc. Results　It was found t hat the size of the right ventricle, PAP, PAR were positively correlated to th e degree of TI. Tricuspid annuloplasty should be carried out in patients with RV D>40 mm, PAR >48 kPa*s/L, PAP>8 kPa. Conclusion　TI resulted ma inly from insufficient function of the right ventricle and marked patholog ical changes of the pulmonary blood vessels. Doppler echocardiography evaluation for the function of right ventricle and pathological condition of pulmonary blo od vessels might be of significant in deciding whether tricuspid annuloplasty sh ould be performed simutaneously in patients of bicuspid valve replacement.

Objective To investigate the predictive value of TNFα,ALT,HBV DNA loads and HBV serological markers in response to adefovir dipivoxil (ADV) treatment for patients with chronic hepatitis B(CHB).Methods Two hundred and three HBeAg.positive CHB patients were administered with ADV 10 mg/d for 48 weeks.HBV serological markers and TNFα at the baseline were determined by enzyme linked immunosorbent assay(EUSA),and HBV DNA loads were detected by PCR.Logistic regression was used to identify predictive factors for serological response at 48th week after the treatment.Results The rates of HBV DNA clearance,ALT normalization,HBeAg lOSS,HBeAg seroconversion and response at 24th week were 31.5%(64/203),59.1%(120/203),15.8%(32/203).8.9%(18/203)and 13.3%(27/203)respectively,while those at 48th week were 58.6%(119/203),78.3%(159/203),29.6%(60/203),16.7%(34/203)and 25.6%(52/203),respectively.Patients who achieved HBeAS loss at 48th week were found to have higher rates of HBV DNA clearance.HBeAg loss and seroconversion at 24th week and higher TNFα at baseline(P=0.017,0.ooI,0.029 and 0.040),while those who achieved HBeAg seroconversion at 48th week were found to have higher rate of HBeAg seroconversion at 24th week.and lower baseline HBV DNA loads(P=0.000 and 0.004).Conclusion For HBeAg.positive CHBpatients with ADV treatment,the rate of HBV DNA clearanee,HBeAg loss and seroeonversion at 24th week and TNFα at baseline may be used to predict the rate of HBeAg 1088 at 48th week:the rate of HBeAgseroconversion at 24th week and baseline HBV DNA loads may be used to predict the rate of HBeAgseroeonversion at 48th week.

Objective To study the safety of transfusion of itraconazole through PICC and to evaluate the effect of different amount of blood transfusion before and after the infusion. Methods Patients were recruited from January 1, 2014, until December 31, 2015, in the Hematology hematopoietic stem cell transplantation ward. Thiry-two patients were recruited in the control group. Ninety patients wererecruited in the experience group. They were randomly assigned to three groups with 30 cases each, extracting different amounts of itraconazole before infusion, back phlebotomize in group A, B, C respectively was 10.0, 0.5, 1.0 ml. Comparing the phlebitis and obstruction after ten days from the transfusion day on. Results Catheter obstruction was not observed in any case. There was a significant difference between control group (21.9%,7/32) and observation group (0) regarding the incidence of phlebitis (χ2=21.157,P < 0.05). No statistical difference was noted among the observation groups regarding the incidence of phlebitis (P>0.05). Conclusions Drawing a small amount of blood volume before itraconazole injection through PICC can effectively avoid the drug-induced catheterobstruction. What′s more, transfusion through PICC can significantly reduce the incidence of phlebitis compared with peripheral infusion.

Objective To explore the effectiveness and safety of Linezolid (LIZ) in treating children with infective endocarditis (IE).Methods The clinical data of 112 children with IE and treated in the Shanghai Children's Medical Center of Shanghai Jiao Tong University School of Medicine from August 2008 to September 2015 were retrospectively analyzed.There were 64 boys and 48 girls,and the age of IE onset ranged from 1 month to 17 years [(6.0 ± 4.8) years].Twenty-nine patients received LIZ treatment ＞ 7 days (LIZ treatment group),including 21 males and 8 females,and the age ranged from 5 months to 15 years [(6.9 ±5.2) years].The remaining 83 patients were identified without LIZ treatment(non-LIZ treatment group),including 43 boys and 40 girls,and the age ranged from 1 month to 17 years [(5.7 ±4.7) years].The etiological results,curative effect and adverse reactions of the LIZ treatment group were observed.Results Among the LIZ treatment group,22 cases had congenital heart disease and 1 case had intravenous catheter.There were 10 cases with infection of staphylococcus aureus,6 cases with coagulase negative staphylococcus,5 cases with oral streptococci and Streptococcus bovis group,3 cases with streptococcus pneumonia,2 cases with enterococcus faecium and 3 cases with negative blood culture results.All cases of the LIZ treatment group received Vancomycin therapy at first,LIZ was given when the Vancomycin therapy failed(16 cases with temperature reiteration,1 case inadequate microbiological response),Vancomycin intolerance (6 neutropenia,2 renal toxicity,2 allergy),and oral maintenance therapy (2 cases).The duration of LIZ treatment ranged from 9 to 135 days [(39.2 ±27.2) days].Three patients (10.3％) had adverse effects during LIZ treatment,1 case with severe digestive symptoms after treatment,1 case with teeth discoloration,1 case with the indicators decreasing by 2 routine blood test.Meanwhile,16 cases of 85 patients (18.8％) had side effects during Vancomycin treatment,in which 7 cases with neutropenia,6 cases with rash and 3 cases with renal insufficiency.But there were no significant differences in adverse effects between LIZ and Vancomycin treatment (x2 =1.l19,P ＞0.05).Twenty-five cases were cured (86.2％) and 2 cases dead (6.9％) in the LIZ treatment group.And no significant difference was found in cure rate,or mortality between LIZ treatment group and non-LIZ treatment group (86.2％ vs.77.1％,x2 =1.090;6.9％ vs.8.4％,x2 =0.069,all P ＞ 0.05) at 6 to 84 (23.9 ± 19.1) months follow-ups.Conclusions LIZ can be used to deal with Vancomycin failure and IE caused by gram positive coccus.LIZ was generally well tolerated in patients with IE.It may be useful in cases of IE complicated by brain abscesses for the good distribution.It is 100％ orally bioavailable,allowing oral administration for outpatients.

Objective To investigate the predictive factors of virological response in HBeAg-positive chronic hepatitis B (CHB)patients treated with adefovir dipivoxil (ADV).Methods A total of 203 HBeAg-positive CHB patients treated with ADV (Mingzheng)10 mg once daily for 48 weeks were recruited.The gene polymorphisms at positions-238 and-308 in tumor necrosis factor (TNF)-α promoter region were determined by the restriction fragment length polymorphism assay of products amplified using polymerase chain reaction (PCR-RFLP).The serum levels of TNF-a at baseline were measured by enzyme linked immunosorbent assay (ELISA).Hepatitis B virus (HBV)genotypes were tested by real-time fluorescent quantitative PCR and HBV subgenotypes were tested by HBV S gene sequencing.Factors related to ADV response were determined by Logistic regression analysis.Results The HBV DNA negative rate,alanine aminotransferase (ALT)normalization rate,HBeAg loss rate and seroconversion rate,and combined response rate at week 24 and 48 of treatment in 203 patients were 31.5% (64/203),59.1% (120/203),15.8% (32/203),8.9% (18/203),13.3% (27/203)and 58.6% (119/203),78.3% (159/203),29.6% (60/203),16.7% (34/203),25.6% (52/203),respectively.HBV DNA negative rate at week 24 was higher in patients with HBV genotype B,that was higher in patients with TNF-α-308G/A genotype,and that was higher in patients with higher baseline ALT level or lower baseline HBV DNA level [OR = 0.405,95 % CI (0.191 - 0.859),P =0.019;OR=0.292,95%CI(0.132-0.643),P=0.002;OR=0.933,95%CI(0.989-0.997),P＜0.01 ;OR=2.089,95%CI (1.412-3.092),P＜0.01].Meanwhile,HBV DNA negative rate at week 48 were higher in patients with higher HBV DNA negative rate at week 24 or higher baseline ALT level [OR=0.029,95%CI(0.007-0.126),P＜0.01;OR= 0.995,95%CI(0.991-0.999),P=0.016].Conclusions HBV genotype,TNF-α-308 genotype,baseline levels of ALT and HBV DNA are predictors of virological response at week 24 in HBeAg-positive CHB patients treated with ADV.And the HBV DNA negative rate at week 24 and baseline ALT level are predictors of virological response at week 48.

OBJECTIVEThis study aims to observe the expression of Sclerostin during movement of orthodontic teeth and determine the effect of this protein on remodeling of periodontal tissues.

METHODSTwenty-four Wistar rats were chosen. Orthodontic forces were applied between the bilateral incisor and first molar to achieve mesial movement. Rats in each group were executed at different time points (0, 1, 3, 5, 7, 14 d). Morphology of periodontal tissue was observed by hematoxylin-eosin (HE) staining. The number of osteoclasts were observed by tartrate-resistant acid phosphatase (TRAP) staining. Sclerostin expression were observed by immunohistochemical staining.

RESULTSHE staining revealed that the resorption of alveolar bone intensified with prolonged movement. Results of immunohistochemical and TRAP staining revealed that Sclerostin expression and number of osteoclasts were related to duration of movement of orthodontic tooth. After staining for 5 days, the number of osteoclasts and Sclerostin expression reached their peak and then began to decline. The numbers of osteoclasts and the expression level of Sclerostin were higher at the compressive side than those at the tensive side.

CONCLUSIONSclerostin affected orthodontic tooth movement by inhibiting the Wnt signaling pathway and by indirectly or directly controlling bone morphogenetic protein.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.
