ObjectiveTo evaluate the therapeutic effect of endoscopic full-thickness resection (EFTR) for gastric stromal tumors.MethodsA total of 33 patients with gastric stromal tumor orgination from deep muscularis propria layer received EFTR from January 2010 to July 2011.The effectiveness and safety of EFTR were compared with those of other 34 patients with gastric stromal tumor origination from muscularis propria layer who underwent endoscopic submucosal dissection (ESD).ResultsExcept in 2 patients with lesions larger than 3.0 × 3.0 cm,EFTR was successful in others 31 patients,who recovered well and had no recurrence during the follow-up within 12 months.There were no significant differences in resection rate,incidence of complications,body temperature,white blood cell counts or recovery time between 2 procedures (P ＞ 0.05 ).However,the number of clips used in EFTR ( 7.0 ± 3.5 vs.4.9 ± 3.1,P =0.013 ) and postoperative fasting days (3.4 ± 1.5 vs.2.0 ± 1.0,P =0.001 ) were significantly higher than those of ESD procedures.ConclusionEFTR is effective and safe for gastric stromal tumors with no higher risk than ESD,but it is more complex technically.EFTR can be used as an expanding method of ESD in endoscopic treatment of gastric stromal tumors.

Objective To compare the results of stroke risk assessment system in patients with non-valvular atrial fibrillation u-sing CHADS2 and CHA2 DS2-VASc .Methods A total of 420 patients with non-valvular atrial fibrillation were evaluated using CHADS2 and CHA2DS2-VASc ,they were divided into three groups according scores :low risk group(scores 0) ,intermediate risk group(scores 1) ,high risk group(scores≥2) .Compare the average scores and the proportions of three groups of two stroke risk as-sessment system .Results The average score of CHA2DS2-VASc was significantly higher than that′s of CHADS2 (2 .41 ± 1 .93 vs . 1 .39 ± 1 .39 ,P<0 .05) .According to scores of CHADS2 ,the proportions of low risk groups were 34 .5% (145/420) ,intermediate risk group were 28 .8% (121/420) ,high risk group were 36 .7% (154/420) .According to scores of CHA2DS2-VASc ,the propor-tions of low risk group were 16 .2% (68/420) ,intermediate risk group were 23 .3% (98/420) ,high risk group were 60 .5% (254/420) .CHA2 DS2-VASc compared with CHADS2 ,the proportion of low-risk group significantly lower than the latter ,the proportion of high-risk groups significantly higher than the latter(P<0 .05) .Conclusion The scores of CHA2DS2-VASc is significantly high-er than that′s of CHADS2 in patients with non-valvular atrial fibrillation ,there are more patients needs anticoagulation using stroke risk assessment system CHA2 DS2-VASc .

Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety.

Objective To clarify the relationship between CT120,a novel human plasma membrane-associated gene,and the proliferation of lung adenocarcinoma cell line A549.Methods Expression vector(pcDNA3.1)containing antisense oligonucleotides of CT120 was constructed and transfected into the adenocarcinoma cell line A549.RT-PCR and Western blot detected the expression of CT120.Meantime,flow cytometry and soft agarose colony formation were applied for cell proliferation,and P53,CyclinD1 and CDK4 were detected by RT-PCR.ResultspcDNA3.1 containing antisense oligonucleotides of CT120 was successfully constructed and inhibited the expression of CT120 effectively by RT-PCR and Western blot.The expression of P53 was up-regulated and the expression of CyclinD1 and CDK4 were down-regulated.Conclusion The down-regulation of CT120 expression by antisense oligonucleotides technique may be a potential drug target for treatment of lung cancer.

OBJECTIVETo study the expression of the Trp-p8 protein in the prostate tissue of the PSA "grey zone" with different PSA density of the transition zone (PSADTZ) and explore the value of determining Trp-p8 expression and PSADTZ in the early diagnosis of prostate cancer (PCa).

METHODSThis study involved 30 cases of benign prostatic hyperplasia (BPH) and another 30 cases of PCa with different PSADTZ values. Using a data imaging and analysis system, we determined the expression levels of Trp-p8 in BPH and PCa tissues and analyzed their correlation with PSADTZ.

RESULTSThe expression of Trp-p8 was weak or negative in the BPH but strong in the PCa tissue and even stronger in the PCa tissue with high PSADTZ (F = 34. 05, P < 0.05).

CONCLUSIONThe Trp-p8 protein is expressed differently in BPH and PCa tissues of the PSA " grey zone" and its expression is positively correlated with PSADTZ. Determination of the Trp-p8 expression and PSADTZ contributes to the early diagnosis of prostate cancer.
