Objective To analyze the human cellular repressor of E1A-stimulated genes (hCREG)using bioinformatics tools and predict the promoter position and transciption factor binding sites.Methods Complete coding hCREG sequences were obtained from Genbank.hCREG was analyzed with First EF software in order to obtain the promoter sequence of hCREG.Moreover,transcription factor binding sites of hCREG was convinced by Motif software.Subsequently,the transcription factor of hCREG by bioinformatics tools was related between hCREG and smooth muscle cells differentiation observed by both Western blot and immunoflourescence.Results The promoter of hCREG was located in -109~-359 bp of up-stream of transcriptional site,which was predicted with 945bp length.Transciption factor binding sites of hCREG was predicted by Motif software which was found with 80 transciption factors.The expression of hCREG and smooth muscle ?-actin(SM ?-actin)increased in HITASY after 72 hours with serum deprivation detected by both Western blot and immunoflourescence.Meanwhile,the results showed that the expression of wtp53 increased significantly.These results suggested that transcription factor wtp53 might regulate the expression of hCREG and promoted dedifferentiated phenotype of VSMCs.Conclusion The transcriptional information of the proximal promoter of hCREG obtained.As up-stream regulational factor of hCREG,wtp53 can up-regulate the expression of hCREG and may play a vital role in the process of VSMCs differentiation and phenotype modulation.

Objective To discuss the feasibility and superiority of EST combined with LC in treating cholecystolithiasiswith common bile duct stones.Methods Patients underwent LC(laparoscopic cholecystectomy) preceded by EST(endoscopic sphincterotomy) and removal of common bile duct stones.ENBD(Endoscopic nasal biliary drainage tube)was placed if EST failure and then the patient underwent LC+laparoscopic biliary duct exploration(LCBDE),or open operative bile duct exploration.Results In 91 of the 99 cases,LC preceded by EST and stone removal was successful,while EST following LC was successful in 3 cases,and stone removal by EST was unsuccessful in 3 cases.Two cases less than 15 years of age underwentLC+LCBDE through the cystic duct and did not undergo EST.Three cases,who had EST failure,underwent LC+LCBDE with primary suture of the common bile duct or LCBDE with T-tube drainage of commonbile duct,or open bile duct exploration with primary suture of the common bile duct(ENBD was in place).All patients were discharged from hospital without serious complications.Conclusions EST combinedwith LC in treating cholecystolithiasis with common bile duct stones is a safe and effective method.Combination of endoscopic and laparoscopic procedures fully reflects the advantage of minimally invasive therapy.

Objective To discuss the significance of the application of real-time quantitative PCR(RQ PCR)for diagnosis and guidance therapy of cytomegalovirus(CMV)infection after allo- hematopoietic stem cell transplantation(allo-HSCT).Methods Thirty-three patients were undergo- ing allo-HSCT.After hematopoietic reconstitution,patients'peripheral blood samples were detected for CMV DNA by RQ-PCR periodically.Anti-viral therapy was begun,attenuated and stopped ac- cording to the results of CMV DNA detection.The effects of anti-viral therapy and patients' clinical results were observed.Results CMV DNA was detected in blood samples from 13 of 33 patients. There were 21 episodes in these patients.Only 1 episode wasn't controlled hecause the patient gave up the therapy.CMV DNA copies were disappeared soon or decreased and then disappeared during anti-viral therapy in the others'.Patients which had symptoms and/or dysfunction of organs were cured too.Each course of anti-viral therapy was shorter than ordinary course.Conclusions CMV in- fection can he diagnosed as early as possible by RQ PCR.To begin,attenuate and stop anti-viral ther- apy according to the results of RQ-PCR is safe.The course is shortened and the side effects of anti vi- ral drugs were attenuated.

Objective To study the effects of HBeAg in new born infants on the response to anti-hepatitis B immunoglobulin combined with hepatitis B vaccination.Methods Two hundred and eight infants who were born during January 2008 to January 2011 in the Department of Obstetrics in Second Affiliated Hospital of Southeast University,including 120 serum HBeAg positive infants without intrauterine infection,and 88 HBeAg negative infants as control group were recruited in the study.Infants in both groups were vaccinated with genetically engineered hepatitis B vaccine (CHO cell) 20 μg according to a standard vaccination regimen (i.e.0,1,6) and 200 IU doses of hepatitis B immunoglobulin immediately after birth and at day 15 respectively.Hepatitis B virus (HBV) serological markers and HBV DNA were measured at birth prior to immunization.HBsAg,HBeAgand hepatitis B surface antibody (anti-HBs) were detected at 1,7,and 12 months after birth to evaluate the effects of immune response.The date were analyzed by the chi-square test and groups were analyzed by t test.Results No statistical significances of anti-HBs were observed between the serum HBeAg positive group and the serum HBeAg negative group at the 1st,7th and the 12th month of birth (t=1.285,0.563 and-0.971,respectively; all P＞0.05).The anti-HBs titers in both groups at 1 month were higher than at birth (P＜0.05).At 7 months after birth,the anti-HBs titers in both groups were even higher than those at 1 month.At 12 months after birth,the anti-HBs titers in both groups were lower than those at 7 months,but still higher than those at 1 month(F=34.3959 and 64.908,respectively; both P＜0.01).Infants who were born with positive serum HBeAg were further divided into two subgroups according to the HBeAg titers,using the median HBeAg titer (47.495 S/CO) as the cut off point.Between the two subgroups,there were also no significant differences of anti-HBs at 1 month,7 months and 12 months (all P＞0.05).The HBeAg titers in HBeAg positive infants decreased gradually after birth.At 7 months,only 3 infants remained HBeAg positive.At 12 months,HBeAg turned negative in all of the 120 infants who were previously HBeAg positive,and no anti-HBe positivity were detected.Conclusion The production of anti-HBs after combined immunization with anti-hepatitis B immunoglobulin and hepatitis B vaccine in infants is independent of HBeAg serology at birth.

In the present study, the effect of the electromagnetic field, induced by radio frequency (RF) coils and coupled with the pelvic tissues, was calculated with the method of finite difference time domain (FDTD). Using the established electromagnetic model of human pelvis region, the simulation was implemented. The imaging uniformity was quantitatively calculated and scaled with the values of the percentage image uniformity (PIU). The electromagnetic model was derived from the anatomical data of human pelvic region and loaded into the simulation. The results showed that the homogeneity of the magnetic fields was severely damaged due to the coupling between the RF coil and the human tissues when loaded with the human pelvis in the Birdcage RF coils at 3T. The research results set a basis meaningful for the design of RF coils.

This study was to investigate the permeability and absorbability of capsaicin cubosome across abdominal skin of the SD rats in vitro. Diffusion of capsaicin cubosome and cream was performed with the modified Franz diffusion cell technique. The capsaicin cubosome showed no enhancement of skin permeation within 24 hours. However, the deposition amounts of capsaicin in the rat skin in the cubosome group was markedly higher than those in the commercial cream group (P < 0.01). Cubosome showed excellent characetristic of skin-targed which could be a good carrier for the local transdermal drug delivery system.

AlM:To study the relationship between JAK-STAT pathway and epithelial - mesenchymal transition in human lens epithelial cells. Meanwhile, the function of AG490 as a JAK inhibitor was also demonstrated in this article.
METHODS:Human lens epithelial cells SRA01/04 ( LECs ) were treated by low concentration of glucose (5. 5mmol/L). High concentration of glucose (30. 5mmol/L) was used to treat the cells in order to form the high glucose model. According to adding AG490 or not, cells were divided into the control group and the experimental group, appropriate concentration 10ü mol/L and 50ü mol/L of AG490 were chosen and acting time of 6, 12, 24, 48h were selected. Effect of AG490 on cell migration was measured by wound healing test. The expression of TGF-β1 , FN,α-SMA mRNA were examined by RT-PCR.
RESULTS:With the prolonged acting time ( 6, 12, 24 and 48h), cell activity increased in the HG group, as well as more expression of TGF-β1 , FN,α-SMA mRNA were detected compared to the LG group (P<0. 05). ln AG490 group, the cell migration activity and expression of TGF-β1 , FN,α-SMA mRNA decreased compared to the HG group (P<0. 05).
CONCLUSlON:JAK-STAT pathway takes part in high glucose-induced epithelial-mesenchymal transition in human lens epithelial cells. The mechanism is that it impacts the transcriptional expression of TGF- β1 and extracellular matrix. AG490, a JAK inhibitor, inhibits high glucose-induced epithelial-mesenchymal transition in human lens epithelial cells, And the inhibition enhances with the increasing concentration of AG490.

OBJECTIVE: To analyze the false-negative proportion and reasons of positioning test in benign paroxysmal positional vertigo (BPPV). METHOD: Sixty-eight cases were reviewed and analyzed during February to April 2009. All patients had typical clinical history of BPPV and diagnosed by positioning test,and all were treated with PRM successfully. If positioning test at the first time were negative, examinations repeated after either head shaking or return visits. RESULT: Thirteen patients (19.12%) appeared false-negative in positoning test, and 11 cases showed typical nystagmus after head shaking,while 2 cases were diagnosed by return visitis the next day. There were no statistically difference between false-negative group and positive group in age (P > 0.05), gender (P > 0.05), course of disease (P > 0.05) and types of semi-circular canal (P > 0.05). CONCLUSION Re-examinations after head shaking or return visits are useful for the diagnosis in the suspected BPPV patients who have negative positioning test.
