Objective To investigate alexithymia , personality characteristic and mental condition in patients with essential hypertension. Methods Fifty-one patients with essential hypertension were assessed using Eysenck personality questionnaire (EPQ), Toronto alexithymia scale (TAS-20) and the symptom checklist-90 (SCL-90). The results were compared with those of Chinese ordinary model. Results The E score of EPQ of the patients with essential hypertension was lower than that of the Chinese ordinary model, while the N, P and L scores was higher. The total score and the scores of all factors of SCL-90 were significantly higher than that of Chinese ordinary model. The total score of TAS-20 and score of factor 1, factor 2 were positively correlated with the scores of all factors of SCL-90, while factor 3 score had no significant correlation with SCL-90. The E score of EPQ was negatively correlated with the scores of all factors of SCL-90, while N and P score were positively correlated with them. Conclusion Patients with essential hypertension were inner personality, unstable psychological status and neuroticism showing alexithymia and obvious psychological symptoms.

BACKGROUND: Dystrophin gene is X-linkage recessive heredity nerve-muscle system disease. Dystrophin gene deletions cluster in two hotspot regions, comprising exons 2-20 and 44-53. The majority of deletions can be detected by examining only a subset of exons. However, little is known regarding systematic detection of 18 common deletion exons of dystrophin gene.OBJECTIVE: To obtain and identify the cloning of 18 deletion-prone exons of dystrophin gene.METHODS: A total of 18 fragments of dystrophin gene were obtained through polymerase chain reaction (PCR) amplification with human genomic DNA as template and 18 pairs of primers respectively. The fragments were connected with pGEM-T Easy vector.The recombinants were transformed into E.coli JM109 competent cells, followed by planted on Luria-Bertani (LB)/ampicillin(Amp)/isopropylthio-β-D-galactoside(IPTG)/X-bromo-4-chloro-3-indolyl-β-D-galactoside (X-Gal) plates and cultured.Positive transformants were selected with blue/white color screening, and the recombinant plasmids DNA was extracted and digested with restriction enzyme Not I. DNA sequences of the fragments were analyzed. Nucleotide analyses were performed through the National Center for Biotechnology Information (NCBI) Basic Local Alighment Search Tool (BLAST) against GenBank.RESULTS AND CONCLUSION: Size of the18 fragments by PCR amplification was in accordance with anticipation. Size of the fragments of recombinant cloning by Not I digestion was in accordance with that of PCR and expectation. Sequence size of the 18cloned fragments was in accordance with expectation. The cloned fragments have high homology with dystrophin gene through NCBI BLAST against GenBank. These cloned fragments were the main deletion-prone exons of dystrophin gene.

PurposeTo explore the value of transesophageal echocardiography (TEE) monitoring mini-incision transthoracic occlusion of ventricular septal defect (VSD) with asymmetric ventricular defects occlude in preoperative selection of patients, intraoperative guidance monitoring and postoperative evaluation.Materials and MethodsForty-five cases of VSD undertook mini-incision transthoracic occlusion with asymmetric ventricular defects occlude were enrolled, their clinical data was analyzed retrospectively, preoperative transthoracic echocardiography (TTE) was applied for choosing appropriate cases. During surgery, TEE was employed for evaluating the VSD and in which perimembranous VSD was found in 21 cases, intracristal VSD in 15 cases and subpulmonic VSD in 9 cases, suitable eccentric type occluders were chosen, guide occluder was placed, and the occlusion effect was evaluated right after operation.ResultsThe procedures were completed successfully in 42 cases, with a successful rate of 93.3%, of which 21 cases had perimembranous VSD, 15 cases had intracristal VSD, and 6 cases had subpulmonic VSD. The diameter of the VSD ranged from 3 to 7 mm, averaging (4.5±0.7) mm, the diameter of occluders ranged from 4 to 8 mm, averaging (5.7±1.2) mm, there was a good positive correlation between size of VSD and occlude (r=0.87,P<0.05). All patients received follow-ups from 3 months to 24 months after operation, all the occluders located normally, with no more than mildly residual shunt, valve regurgitation or severe arrhythmia discovered.ConclusionMini-incision transthoracic occlusion of ventricular septal defect (VSD) with asymmetric ventricular defects occlude has high success rates, minimal injury, and lower complication rate. TEE can play a vital role by improving the success rate and safety of surgery.

Objective:To systematically evaluate the influence of the implementation of essential drug policy ( EDP) on prescrip-tion use rate of antibiotics in primary hospitals. Methods:Based on CNKI, Wanfang and VIP of China journal databases, all litera-tures were adopted including the data of the prescription use rate of antibiotics in primary hospitals. RevMan5. 3 and Stata 12. 0 soft-ware were used to conduct the Meta analysis. Results:Totally 43 literatures were included in the study according to the evaluation se-lection criteria. After the implementation of EDP, the prescription use rate of antibiotics in primary hospitals was decreased, and com-pared with that before the implementation of EDP, the risk difference value was significant [RD= -0. 03,95%CI( -0. 04,-0. 03), P<0. 000 01], while the use rate was still high (46. 16%). The result of Egger’s test indicated the publication bias of the 43 litera-tures was not significant (P=0. 571). However, there was high heterogeneity(I2 =94%,P<0. 000 01)among the different studies. Based on the classification of hospital type and different areas, the results of sub-group analysis showed the differences of study methods in the literatures and regional implementation measures of EDP contributed to the high heterogeneity among the different studies. Con-clusion:In order to reduce the heterogeneity of studies, a unified evaluation criteria for the research quality of the cross-section survey should be established. And special policies related to EDP should be taken to effectively decrease the use rate of antibiotics in primary hospitals.
