The conception of evidence-based medicine (EMB) has a strong influence on the medical world since it built up.This concept has been widely used in all sorts of clinic and basic medical research,however,it is little reported to be practised in our fundamental medical education.As for it,this article will briefly analyze the importance of introducing the idea into fundamental medical education,and for one thing,suggest some more reform measures for medical teaching staff.

Objective: To construct the recombinant vaccinia virus of mutant N-ras/61 gene and enhance the immunogenecity of mutant N-ras／61 protein produced by the recombinant vaccinia virus. Methods: N-ras／61 gene was inserted into P1108 and transfected into CV-1 cell infected with vaccinia virus by Cell FECTIN. PCR and Western blot were used to identify the recombinants. Results: We get recombinant vaccinia virus rV-N-ras/61 by PCR and tk- selecting. The expression of N-ras gene was detected by Western blot. Conclusion: This study is a test for studing effective vaccine of mutant N-ras/61 gene. The efficacy in vivo of the N-ras／61 vaccine in immunotherapy is under investgation.

Objective To explore early diagnosis and treatment of congenital esophageal atresia and tracheoesophageal fistula.Methods Clinical data of 11 patients with congenital esophageal atresia and tracheoesophageal fistula were analyzed retrospectively.Definite diagnoses were made for all cases in 24 hours through making an esophagus opacification with acetrezoic acid or iodinated oil.And an esophagus anastomosis outside pleura was made.Some experience of diagnosis and therapy were summarized.Results All of the 11 cases underwent operation.Among them,9 cases were cured (81.8%),and 2 cases died(18.2%).Anastomosis stenosis of esophagus was found in 1 case after operation,which was cured through esophagus dilatation.Tracheoesophageal fistula was found in another case after operation and it was cured through combined treatment including anti-infection, nutritional support and sufficient draining.Conclusion Early diagnosis and surgical treatment, postoperative care,prevention and cure of complication are very important to improve the survival rate of the patients with congenital esophageal atresia and tracheoesophageal fistula.

Objective To detect Chlamydia trachomatis phage Vp1 gene in clinical swab specimens and anti-Vp1 antibodies in serum specimens.MethodsCervical and urethral swab as well as serum specimens were collected from attendees to the sexually transmitted disease(STD) clinic in the Tianjin Institute of STD,during March 2008 to March 2011.PCR was conducted to detect chlamydial phage Vp1 gene in swab samples,enzyme linked immunosorbent assay(ELISA) and Western blot to detect anti-Vp1 antibody in sera.The swab specimens positive for Vp1 gene were subjected to cell culture followed by the detection of Vp1 protein with an immunofluorescence-based method.ResultsTotally,36 out of 1542 swab specimens turned out to be positive for Vp1 gene,and 23 out of 453 serum specimens for anti-Vp1 antibody.No positive results were obtained in the Vp1 gene-positive swab specimens by cell culture and immunofluorescence-based assay.ConclusionThe Vp1 gene of Chlamydial trachomatis phage and anti-Vp1 antibody are successfully detected from clinical swab and serum specimens respectively.

Objective To measure the range of routine blood counts and blood biochemical parameters ,to analyze hemorheology of the rats with congenital cataract .Methods Blood samples were taken from 90 rats with congenital cataract weight about 185 ~211 g.Routine blood analysis was performed and blood biochemical and hemorheology paramenters were determind using an automatic blood biochemical and hemorheology analyzer .Results There were no significant difference ( P >0.05 ) between the cataract rats and the normal rats in Blood test results; but there were significant difference between the microphthalmos cataract rats and the normal same -sex rats ( P <0.01 or P <0.05 ) . The biochemical results is the cataract rats and the normal rats were different significantly in ALB group ( P <0.01 or P<0.05), and the female microphthalmos cataract rats compared with the control rats had significant difference in Ure (P<0.01) , the female cataract rats ompared with the normal rats were very significant difference in Cr group ( P <0.05 or P <0.01).The erythrocyte counts of the male cataract rats and male microphthalmos cataract rats were significantly lower than that in the female ones, respectively(P <0.05, P <0.01).The platelet counts of the male cataract rats and the male microphthalmos cataract rats were significantly higher than that in the female ones , respectively(P <0.01), and the creatinine of the male cataract rats and the male microphthalmos cataract rats were significantly lower then that in the female ones, respectively(P <0.01).There were no significant difference in every group on hemorheology .Conclusions There were significant differences in some blood indexes between the congenital cataract rats and the normal rats .These data may become useful reference for biomedical researcher in this field .

Eight patients with suspected cases of C .jejuni were etiologically diagnosed and analyzed in this study to pro-vide scientific basis for the confirmation of the cases of human campylobacteriosis in Guizhou Province ,China .Blood or feces of 8 suspected patients were employed to isolate bacteria strains .Conventional and multi-PCR techniques were applied to identify suspicious bacteria strains .The C .jejuni strains were analyzed by using Pulsed Field Gel Electrophoresis (PFGE) .Suspicious strains of C .jejuni were isolated from all the 8 suspected patients of campylobacteriosis and anticipated genes fragment were detected with multi-PCR .With the digestion of restriction enzyme SmaI ,the 8 C .jejuni strains were divided into 7 PFGE pat-terns with 7-10 DNA bands .Cluster analysis showed that the gross similarity of 8 strains of C . jejuni was more than 50% . The similarity of PFGE patterns between strain GZ201004 and GZ201005 from diarrhea patients was as high as 100% ,while the similarity of strain GZ201201 and GZ201007 was 66 .7% .Moreover ,C . jejuni were detected from all the suspected pa-tients of campylobacteriosis .PFGE results indicated that strains GZ201004 and GZ201005 were from the same source ,while all the 8 isolates showed PFGE polymorphism .

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL
