OBJECTIVETo study the viremia formation in guinea-pigs infected with wild type and attenuated Japanese encephalitis virus (JEV).
METHODSGuniea pigs were inoculated intraperitoneally with different wild JEV strains and the attenuated vaccine strain and its parent virulent strain. Viremia was detected on different days following virus inoculation.
RESULTSAll the guinea-pigs inoculated with the wild JEV strains induced different levels of viremia (1.00-3.40 Lg pfu) on the 1st and 3rd day post inoculation. Using a virus titer of 10(4) pfu for inoculation, the animals inoculated with the SA14 parent strain induced relatively high viremia (10(2.4)-10(3.4) pfu), however no viremia coulds be detected on any tested days.
CONCLUSIONThe degree of viremia in guinea pigs can be used as a new method to evaluate the attenuation of JEV.

With the kernel of efficacy, "Xiaohe Silian" was a pattern and method for new drug discovery which was constituted with "metabolism-efficacy, toxicity-efficacy, quality-efficacy and structure-efficacy". Its connotation was in keeping with traditional Chinese medicine (TCM) clinical pharmacy. This paper systematically summarized the research method of new drug discovery practice process for TCM. To avoid western drug like in TCM new drug discovery, we carried out combination analysis with TCM clinical pharmacy. The correlation analysis between basic elements of "Xiaohe Silian(n) and TCM clinical pharmacy was studied to guarantee this method could integrate closely with TCM clinic from all angles. Hence, this method aimed to provide a new method for TCM new drug discovery on the basis of TCM clinical pharmacy with insisting on holistic view of multicomponent study, kinetic view of metabolic process when the curative effect occurred and molecular material view of quality control and structure-activity exposition.

Objective To explore the effects of diagnostic delay on early disease course of Crohn's disease (CD ), and to analyze the risk factors related with the progress of early disease course. Methods From December 2014 to July 2017,a total of 56 patients in Renmin Hospital of Wuhan University initially diagnosed as CD were selected.The clinical manifestation,previous history,imaging examination, endoscopic examination and pathological results of the patients were collected after initial diagnosis of CD. CD-related surgery,CD-related rehospitalization and use of immunomodulators were followed.According to time interval between initial symptom onset and initial diagnosis,the patients were divided into diagnostic delay group (diagnostic delay time>two years,14 cases)and non-diagnostic delay group (diagnostic delay time≤two years,42 cases).The clinical characteristics at initial diagnosis and early prognosis were compared between the two groups.The risk factors affecting early prognosis of CD patients were analyzed. Kaplan-Meier was used for prognosis analysis.Log-rank test and Cox proportional hazards model were performed to analyze factors affecting early prognosis.Results The results of imaging examination indicated that the proportion of intestinal injury of diagnostic delay group was significantly higher than that of non- diagnostic delay group (χ2= 4.49,P = 0.03 ).During follow-up,the proportion of CD-related rehospitalization of diagnostic delay group was higher than that of non-diagnostic delay group,and the difference was statistically significant (χ2=7.34,P=0.01).During follow-up,the nine patients received surgery.The one-year and three-year cumulative incidence of surgery was 10.7% and 22.7%,respectively;one-year cumulative incidence of surgery in diagnostic delay group and non-diagnostic delay group was 38 .6%and 9 .6%,respectively.The results of Cox univariable and multivariable analyses both indicated that intestinal injury in imaging examination at diagnosis was the risk factor of surgery (both hazard ratio (HR)=2.313,both P<0.01).A total of 21 patients had CD-related rehospitalization during follow-up.And one-year and 31-month cumulative incidence of hospitalization was 27 .8% and 5 6 .3%,respectively;one-year cumulative incidence of CD-related rehospitalization in diagnostic delay group and non-diagnostic delay group was 43 .7% and 2 1 .6%,respectively;and the difference was statistically significant (χ2=5 .88 ,P=0.02).The results of Cox univariable analysis indicated that having systematic manifestation,intestinal inj ury in imaging examination and diagnostic delay were the risk factors of CD-related rehospitalization (HR=2.972,2.313 and 1.403,all P<0.05).The results of multivariable analysis indicated that having systematic manifestation and intestinal injury in imaging examination were independent risk factors of CD-related rehospitalization (HR=3.891 and 2.541, P < 0.01,respectively).Conclusions The proportion of intestinal injury of patients with diagnostic delay is high and the early prognosis is poor. Intestinal injury in imaging examination at initial diagnosis is independently risk factor of CD-related surgery and rehospitalization during follow-up.
