Objective: To construct the eukaryotic expression vector pSurp-EGFP regulated by the survivin gene promoter and to detect the specific expression of the promoter in human laryngeal cancer Hep-2 cells by green fluorescent protein assay.Methods: Thesurvivin gene promoter was generated by polymerase chain reaction(PCR) and the CMV promoter of the pShuttle vector replaced by the survivin gene promoter to generate the plasmid pSurp.The three plasmids pShuttle,pSurp and pEGFP-C1 were respectively double-enzyme digested so as to produce the plasmids pCMV-EGFP and pSurp-EGFP carrying the CMV or survivin promoter.The purified pCMV-EGFP and pSurp-EGFP were transfected into Hep-2 cell and vascular endothelial cell ECV304 using liposome transfection reagent and the expressions of EGFP detected by the fluorescent microscope.Results: Thesurvivin gene promoter was successfully cloned by PCR,and thesurvivin gene promoter-regulated pSurp-EGFP was constructed.Green fluorescence was observed in Hep-2 cells but not in ECV304. Conclusion: The high specific activity of the survivin gene promoter in Hep-2 cells that we successfully constructed attributes to the studies of tumor specific gene therapy.

Objective To summarize the risk factors, the diagnostic and therapeutic approaches, and the outcomes of the ruptured primary hepatocellular carcinoma (PHC) occurred after transcatheter arterial chemoembolization (TACE) in order to make a further understanding of this complication. Methods The clinical data of 8 patients with ruptured PHC after TACE, who were encountered at the First Affiliated Hospital of Suzhou University during the period from Sep. 2007 to Sep. 2013, were retrospectively analyzed. Results A total of 1379 times of TACE were performed in 678 patients with PHC. Among the 678 patients, 8 developed rupture of PHC with bleeding after TACE. The overall incidence was 1.2%. The mean diameter of the tumors in the 8 patients was (11.5 ± 2.6) cm, ranging from 7.6 cm to 15.9 cm. All the lesions were located at the peripheral region close to the liver capsule, and most of them protruded outward. Five cases had coexisting portal hypertension. The average dosage of Lipiodol used in TACE was (14.9 ± 4.5) ml with a range of (8 - 20) ml. Of the 8 patients, emergency transcatheter embolization was carried out in 4 and medical management was employed in other 4. Seven patients died as all active emergency treatments failed. Only one patient, who had received emergency transcatheter embolization, survived the ruptured PHC. Conclusion Rupture of primary hepatocellular carcinoma after TACE is a rare, but very serious complication. Its occurrence may be related to lesion’s characteristics, such as large tumor size, superficial location and protrusion from the liver surface, etc. Besides, interventional management, e.g. without use of solid embolic material to enhance the embolization effect, may also be responsible for the rupture.

Quantitative analysis and developmental observations on the planum temporale of 157 fetus and infantal brains have been made. The results are as follows: 1) left planum temporale of 82％ of the fetal brains and 76％ of the infantal brains are larger than the right. 2) Average area values of the left planum temporale are signifcantly larger than the right. 3) The earliest appearance of the planum temporale is in the sixth gestational month. 4) Rate of appearance of the left planum tempo-rale in fetuses is higher than that of the right. 5) Right/left ratio of planum temporale increases with the development of the embryo. These findings indicate that the asymmetry of the left and right planum temporale is present since the appearance of the planum temporale, and changes as the fetus develops.

Objective To systematically evaluate the relationship between p53 gene codon72 polymorphism and onset risk of prostate cancer (PCa) among Asian population by meta-analysis.Methods The databases of PubMed,Medline,Ovid,Wanfang and CNKI were retrieved for screening the case control trials on the relationship between p53 gene codon72 polymorphism and onset risk of PCa among Asian population.The obtained data were statistically analyzed by using the Stata 12.0 software,moreover the data reliability and publication bias of statistical literature were evaluated.Results The meta analysis showed that the p53 gene codon72 polymorphism had no obvious correlation with PCa onset risk in Asian population.The subgroup analysis results on the control source showed the coden72 polymorphism in P vs.A,PP vs.AA,PA+PP vs.AA models based on the hospital source subgroup could significantly decrease the Pca susceptibility among Asian population[P vs.A:OR =0.680,95 ％ CI(0.546,0.847),P=0.001;PP vs.AA:OR=0.409,95％CI(0.260,0.645),P=0.000;PA+PP vs.AA:OR=0.513,95％CI(0.350,0.749),P=0.001],whereas the codon 72 polymorphism in PA vs.AA and PA+PP vs.AA genotypes in the control source subgroup based on the common population increased the PCa onset risk among Asian population [PA vs.AA:OR=1.664,95 ％CI(1.272,2.177),P=0.000;PA+ PP vs.AA:OR =1.314,95 ％ CI(1.020,1.693),P =0.003 6].The subgroup analysis was conducted according to whether conforming to the HWE equilibrium,the results showed p53 gene codon 72 polymorphosm was a protective factor for decreasing PCasusceptibility among Asian population in the subgroup unconforming to the HWE equilibrium [PP vs.AA:OR=0.251,95％CI(0.135,0.467),P=0.000;PA+PPvs.AA:OR=0.564,95％CI=(0.330,0.964),P=0.036].Conclusion p53 gene codon72 polymorphism has no relation with PCa susceptibility among Asian population.

Objective To study the effect of laparoscopic myomectomy on the curative effect and postoperative rehabilitation of patients with uterine fibroids (UM).Methods From March 2014 to March 2016, selected 84 patients with UM in the people's hospital of Baoding Xushui district were divided into observation group (n=43) and control group(n=41) according to the different operation procedures, the observation group were treated with laparoscopic myomectomy and the control group were treated with open uterine fibroids.Serum T cell subsets (CD4+, CD8+, CD4+/ CD8+) between the two groups before and 1 day after operation were compared, and CA125, Cor, IL-1β levels, and surgery condition, postoperative recovery, complicationsand postoperative 12 months of recurrence were statistically compared.Results The serum CD4+, CD8+, CD4+/CD8+ levels in the observation group were significantly higher than those in the control group at 1 day after operation, the difference was statistically significant (P<0.05);the first exhaust time and hospitalization of the observation group were significantly shorter than those of the control group, and the intraoperative blood loss and postoperative pain score (VAS) were significantly lower than those in the control group (P<0.05);The incidence of postoperative complications in the observation group (6.98%, 3/43) was significantly lower than that in the control group (26.83%, 11/41), by follow-up, the recurrence rate (2.33%, 1/43) was lower than that of the control group (19.51%, 8/41), the difference was statistically significant (P<0.05).Conclusion Treatment of uterinemyoma using laparoscopic myomectomy gets a significant effect, and the body inflammation, stress response lighter and the effect of immune function is small, which can reduce the postoperative complications and recurrence rate and promote the rehabilitation of patients, and less impact on immune function.

OBJECTIVE The diagnosis of drug allergy is difficult and is usually based on clinical history,skin tests(for some drugs) and,in a few specialized allergy centers,provocation tests.To establish the method for analyzing basophil activation test(BAT) by flow cytometry(FCM) and evaluate its clinical significance in the diagnosis of drug allergy.METHODS The protocol for FCM analysis of basophil degranulation in allergy dustmite by CD63,CD203c and CD45 combination was established.The clinical significance of activated basophil by FCM was evaluated by comparing with the results of sIgE by fluorescence enzyme-linked absorbent assay(FELISA),regarding the skin prick test as the gold standard.RESULTS Pure basophils were got by CD45 and CD203c gating,CD63 was the best marker for activated basophil;Spearman′s correlation coefficients indicated a moderate positive correlation between SIgE class categorized by Unicap class and activated basophil;there was no significant difference between activated basophil by FCM and sIgE by FELISA in the diagnosis of allergic reaction,but the former was better than the latter in specificity and positive likelihood ratio.CONCLUSIONS Quantification of activated basophil by CD63 expression with FCM is a valuable new and safe method in vitro for diagnosis of immediate type hypersensitization.
