AIM: To investigate the pharmacological effects of recombined basic fibroblast growth factor (rbFGF) on retinal ganglion cells (RGCs) of rats. METHODS: Using calibrated cross-action forceps a moderate crush injury was inflicted on the nerve. After crush injury, rbFGF, saline and VB 12 were administered by retrobublar injection. Four weeks after injury , the apoptosis of RGCs was measured with flow cytometer. RESULTS: Four weeks after operation, it was shown that the rbFGF, but not saline or VB 12 injection could significantly improve the maintainance of RGCs of rats. After 800 U, 1600 U and 2400 U rbFGF injection, the injured RGCs were rescued by 24.5%, 27.3% and 28.5% respectively. Furthermore, it was also found that rbFGF injection could effectively prevent the axons from injury. The flow cytometer showed that the rate of apoptosis was reduced markedly on 7 days at rbFGF group. CONCLUSION: rbFGF can significantly promote the functional repair of injured optic nerve. [

OBJECTIVE:To observe the clinical efficacy and safety of flunarizine combined with salvianolate in the treatment of acute migraine. METHODS:A total of 72 patients with acute migraine were randomly divided into control group(36 cases)and observation group (36 cases). Based on routine treatment,control group was given Flunarizine hydrochloride capsules orally,10 mg for 65 year-old and below once a day,5 mg for more than 65 year-old once a day. Observation group was additionally given Flunarizine hydrochloride for injection 200 mg intravenously,once a day,on the basis of control group. Both groups were treated contineously till cured or for 2 weeks. Clinical efficacy,onset time,recovery time,VAS score,frequency and duration of head-ache attack,ADR were observed in 2 groups. RESULTS:In the course of treatment,the two groups did not terminate and fall off, and all of them completed the treatment. The total response rate(97.22%)of observation group was significantly higher than that (86.11%)of control group;onset time and recovery time of observation group were both shorter than those of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in VAS score,frequency or duration of headache attack between 2 groups (P>0.05). After treatment,VAS score,frequency and duration of headache attack in 2 groups were all significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLU-SIONS:Based on routine treatment,flunarizine hydrochloride capsules combined with Salvianolate injection show significant effica-cy for acute migraine with good safety.

OBJECTIVETo investigate the predictive value of HCV RNA in PBMC of patients with chronic hepatitis C to IFN treatment.

Objective To explore the prevalence of self reposed mania/hypomania symptoms of depressive disorders and the difference between the two self-rating symptoms questionnaires in setting of psychiatric clinic of a general hospital.Methods 102 outpatients who were diagnosed with depressive disorders by ICD-10 in department of psychiatry of Tongji Hospital of Tongji University were continuously investigated and fulfilled the Chinese Version mood disorder questionnaire(CV-MDQ)and the Chinese Version 32 items hypomania check list(CVHCL-32).The positive mania symptoms were elevated with at least seven positive mania items reported by the CVMDQ.The positive hypomania symptoms were elevated with at least fourteen positive hypomania items reported by the CV-HCL-32.Results The internal consistency(Cronbach alpha)of the CV-MDQ was 0.808(95% CI=0.767～0.845,P<0.01).The internal consistency(Cmnbach alpha) of the CV-HCL-32 was 0.916(95% CI=0.898～0.930,P<0.01).11 patients(10.8%) reported positive mania symptoms by the CV-MDQ.14 patients (13.7%)had been reported positive hypomania symptoms through the CV-HCL-32.The ability of discriminating mania or hypomania between the two scales was significantly different(Kappa=0.227,P<0.05).Compared to the patients who were reported negative hypomania symptoms by the CV-HCL-32.the 11 patients with positive hypomania symptoms by the CV-HCL-32 had much earlier age in first episode(35.0 vs 50.5,z=-2.065,P<0.05),much longer months in total disease course(60.0 vs 22.0,z=-2.102,P<0.05)and present episode (12.0 vs 6.0,z=-2.180,P<0.05),and much higher frequency of relapse(2.5 vs 1.0,z=-2.168,P<0.05),but no significant differences at age,gender and education.No significant differences appeared between CV-MDQ positive and negative group.Conclusion Mania or hypomania symptoms may be screened by CV-MDQ and CV-HCL-32 from the outpatients with depressive disorders who are diagnosed by ICD-10 in general hospital.whether CV-HCL-32 is superior to CV-MDQ when screening bipolar Ⅱ disorder is worthly further study.

Objective:To investigate the effect of DKK1 on linearly patterned programmed cell necrosis (LPPCN) and vasculogenic mim-icry (VM) and the related molecular mechanism in non-small cell lung cancer (NSCLC). Methods:A total of 173 human NSCLC speci-mens were collected to detect LPPCN by H&E staining, detect VM with CD31/PAS double staining, and investigate DKK1 and related protein expression by immunohistochemistry. The clinical pathological significance of LPPCN, VM, and DKK1 and the correlation of them were analyzed. Human NSCLC H460-DKK1 cells were engrafed in nude mice to evaluate the influence of DKK1 up-regulation on VM and LPPCN in vivo. Results:Approximately, 14.45%(25/173) of NSCLC had VM and 49.71%(86/173) had LPPCN. 25.6%(22/86) of NSCLC cases in LPPCN-positive group formed VM. Both of VM and LPPCN were all correlated with poor differentiation, late TNM stage, easy recurrence and metastasis and poor prognosis in NSCLC. DKK1 expression in the VM-positive group and the LPPCN-positive group was higher than that in the VM-negative group and the LPPCN-negative group, respectively. DKK1, LPPCN, and VM were positive-ly correlated with VE-cadherin, MMP-2,β-catenin nuclear expression and Twist1. H460-DKK1 transplantation tumor model confirmed that DKK1 promotes the expression of VM and LPPCN and related proteins in NSCLC. Conclusion:The increase of theβ-catenin and Twist1 expression induced by DKK1 may promote the formation of LPPCN and VM in NSCLC.

Objective To provide the reference for schistosomiasis control through analyzing the changes of endemic status of schistosomiasis in China in recent years. Methods The annual data of schistosomiasis prevention and control from 2002 to 2012 were collected, and the descriptive analysis was conducted to describe the changes of schistosomiasis endemic status. Re?sults Sichuan, Yunan and Jiangxi provinces reached the criteria of transmission controlled from 2002 to 2010 while Hubei, Hu?nan, Jiangxi and Anhui provinces reached the criteria of infection controlled in 2008. The number of counties where the trans?mission of schistosomiasis was controlled decreased from 110 in 2002 to 80 in 2010. The numbers of estimated schistosomiasis cases and reported acute cases fell from 810.4 thousands and 913 in 2002 to 325.8 thousands and 43 in 2010, respectively, and they were reduced by 59.79%and 95.40%respectively. The number of infected bovine went down from 23 199 in 2002 to 7 173 in 2010, with a fall of 69.03%. However, the Oncomelania hupensis snails breeding areas kept in 3.7 to 3.8 billion m2 and among which, 125 million m2 areas were newly discovered in non?endemic areas during the nine years. In 2010, 90%of schistosomiasis cases, acute cases, infected bovine, and snail breeding areas were concentrated in 5 provinces, especially in the Dongting Lake and Poyang Lake areas and the regions along the Yangtze River. Conclusions The epidemic of schistosomiasis decreased sig?nificantly from 2002 to 2010. The lake regions are the key and tough areas for schistosomiasis prevention and control. To consoli?date the achievements, the surveillance and case management need to be strengthened as the extension of snail breeding areas and acute cases reported from other places becomes common.

Chlamydia psittaci is a causative agent of psittacosis,which can infect a wide range of hosts including birds and humans.However,information regarding C.psittaci infection in pigeons is scarce.In the present study,a total of 399 fecal samples from pigeons were collected from Jilin Province,northeastern China,between March and May 2015,and examined by nested PCR amplification of outer membrane protein A (ompA) gene.The overall Chlamydiosis prevalence was 5.01％ (21/399),with 3.19％ in Changchun City and 9.40％ in Jilin City.Furthermore,breed was the major risk factor associated with Chlamydia infection in pigeon,boiler pigeons had a prevalence of 7.49％,whereas no C.psittaci was detected in racing pigeons.Sequence analysis of the ompA gene revealed that all the identified isolates represented C.psittaci genotype B.Our results firstly indicated the presence of zoonotic C.psittaci in boiler pigeons in Jilin Province,northeastern China,and effective measures should be implemented to reduce the risk of C.psittaci transmission from pigeons to humans.
