Objective To discuss the relationship between Hp eradication effect and TCM syndrome types, and provide basis for improving clinical Hp eradication rate of TCM. Methods TCM syndrome types of 922 Hp-positive patients were distinguished. After treatment by the quadruple chemotherapy, the effect of Hp eradication of different TCM syndrome type was analyzed. Results In 922 Hp infectors, Hp eradication effect in different TCM syndrome type from low to high was as follows:spleen-stomach deficiency-coldness, cold-heat complication, stomach-yin deficiency, congestion of stomach collaterals, hyperactive liver-qi harmful to stomach, liver-stomach heat, spleen-stomach dampness-heat, with significant difference (P<0.05). A total of 623 patients were discriminated as excessive syndrome (including spleen-stomach dampness-heat, liver-stomach heat, hyperactive liver-qi harmful to stomach and congestion of stomach collaterals), and its eradication rate was 82.5%. A total of 244 patients were discriminated as deficient syndrome (including spleen-stomach deficiency-coldness and stomach-yin deficiency), and its eradication rate was 58.6%. The difference between excessive syndrome and deficient syndrome was statistically significant (P<0.05). Hp eradication effect among different TCM syndrome types of excessive syndrome had statistical difference (P<0.05), while that of deficient syndrome had no statistical difference (P>0.05). Conclusion The eradication rate of Hp infection was different in patients with different TCM syndrome types, which in deficient syndrome is obviously lower than in excessive syndrome.

Objective To investigate the clinical significance of N-terminal pro-B-type natriuretic peptide(NT-proBNP) detection in evaluation of acute type A aortic dissection (AAAD) prognosis .Methods Medical records of patients with confirmed diagnosis of AAAD were retrospectively analyzed .64 patients were enrolled in accordance with the inclusion and exclusion criteria ,and were di-vided into survival group(n=56) and death group(n=8) according to prognosis .Multivariate Logistic regression analysis was em-ployed to screen the independent risk factors which would affected the prognosis .Receiver operator characteristic ,ROC) curve was used to evaluate the predictive value of NT-proBNP for AAAD prognosis .Results Differences of history of smoking ,incidence sea-son ,disturbance of consciousness ,misdiagnosis ,low density lipid-cholesterol(LDL-C) ,fasting C-peptide(FCP) ,hypersensitive C-re-active protein(hs-CRP) ,cardiac troponin I(cTnI) ,NT-proBNP ,mean arterial pressure(MAP) and prothrombin time(PT) of pa-tients between the survival group and the death group showed statistical significance (P<0 .05) .Multivariate Logistic regression a-nalysis demonstrated that smoking history ,disturbance of consciousness ,high LDL-C ,high cTnI ,high NT-proBNP and low MAP were independent risk factors for patients with poor prognosis .ROC area under the curve(AUC) of NT-proBNP prediction for peri-operative mortality risk of patients with AAAD was 0 .697(P< 0 .05 ,95% CI:0 .643~0 .733) ,and its specificity and sensitivity were 75 .85% and 70 .07% ,respectively .When NT-proBNP was 909 .69 pg/mL ,its predictive value for AAAD was the best .Set the critical value as the threshold ,the patients above were divided into the threshold above group and the threshold below group . The survival rate of patients in the threshold below group [98 .18% (54/55)] was significantly higher than that in the threshold a-bove group[22 .22% (2/9)](χ2 = 7 .211 ,P< 0 .05) .Conclusion NT-proBNP level is closely related to the prognosis of patients with AAAD and NT-proBNP detection may be conducive to predicting high risk of AAAD .

Idiopathic pulmonary fibrosis ( IPF) is a kind of Interstitial lung disease with cause unknown,which is aggressive for its increasing prevalence and high morbidity and mortality.At present the pathogenesis of IPF is not entirely clear, but cells and cel-lular interactions play a decisive role on the alveolar inflammation and fibrosis results.We review IPF related cells of interest ( immune competent cells and fibroblast, fibrocyte, myofibroblast, endothelial and alveolar epithelial cells) , to summarize cells and cellular in-teractions in the pathogenesis of IPF,and discuss new research directions and therapeutic targets.

Objective To study the influence of Noradrenergic systems in Lateral Hypothalamus Area (LHA) on small intestine moving. Methods The effect of noradrenalin、noradrenalin+phentolamine、noradrenalin+propolol、phentolamine on small intestines electro-activity of rats was detected by external alimentary canal electrodes and central nervous system stereo-configuration technology. Results After injecting 2 g/L noradrenaline (NE) the cyclic period of MMC extended, the ratio of the active time to the cyclic period and the number of the fast wave within the active time per minute reduced. NE inhibited the electro-activity of small intestine of rats, and the average effective time was (36.86?7.39)min. Hence injecting 5 g/L PE alone to LHA raised the ratio of the MMC active time to the cyclic period. Phentolamine presented a slight excitability on the electro-activity of small intestine of rats. Conclusion The NE in LHA showed the inhibitive myoelectric activity on small intestines, and this effect was introduced through a acceptor,The reacceptor in LHA may function in the inhibition of the electro-activity in small intestines.

OBJECTIVE To evaluate the disinfecting effect of electrolyzed-oxiding water(EOW) on dental(instruments) contaminated after clinical operation.METHODS Use K-reamer and high-speed handpiece as objects of test.(K-reamers) were disinfected by EOW and 2% glutaraldehyde for 5min and 10min,respectively.And(handpieces) were disinfected by EOW and autoclave sterilization,respectively.The samples were collected from each(K-reamer) and each handpiece′surface and its water-canal before and after disinfection.The samples were done germiculture.RESULTS Disinfecting K-reamer for 10min,the disinfection rate of two disinfectants(EOW and 2%(glutaraldehyde)) were both 100%.Disinfecting handpiece with EOW(by surface-wiping,immersing and rinsing the water-canal)or autoclaving sterilization,the disinfection rate of EOW and 2%glutaraldehyde were both 100%.(Disinfecting) handpiece with EOW(by surface-wiping,immersing and rinsing the water-canal) or autoclaving(sterilizaion),the bacteria contaminated on handpiece′s surface and in the water-canal could all be killed,while(disinfecting) handpieces with EOW only by surface-wiping,and immersing,in the water-canal there were still a lot of bacteria.CONCLUSIONS The disinfecting effect of EOW is reliable and safe compared with 2%(glutaraldehyde) and autoclave sterilization.

Objective To evaluate the feasibility of automatic tube current modulation(ATCM) in craniocervical artery CT angiography with 256-slice CT,while maintaining the image quality.Methods Sixty patients undergoing craniocervical artery CTA were enrolled into this study,and were divided into conventional tube current group(250 mAs,group A,n=30) and low tube current group(ATCM,group B,n=30).The signal-to-noise ratio(SNR),contrast-to noise ratio(CNR),volume CT dose index(CTDIvol) and effective dose(ED) were evaluated respectively.Results The mean image SNR was(37.47?9.39) and(36.85?7.96) for group A and group B respectively,and was not significantly different(P=0.79).The mean image CNR was(32.13?9.06) and(31.86?7.66) for group A and group B respectively,and was not significantly different(P=0.90).The CT volume dose index(CTDI) was 16.5 mGy and 410.55?0.94mGy for group A and group B respectively,and was significantly different(P

Objective To investigate whether the apoptosis-2 ligand (Apo-2L),known as tumor necrosis factor-related apoptosis-inducing ligand (TRAIL),could enhance irradiation-induced apoptosis in lung adenocarcinima H1975 cells that are resistant to the epithelial growth factor receptor (EGFR)-TKI.Methods Adenocarcinima H1975 cells were randomly divided into four groups:the control group,Apo2L group,irradiation group,and both Apo-2L and irradiation group.H1975 cells were pretreated with Apo2L under different concentrations of 200 and 228 ng/ml at 24 h before irradiation with doses of 1,1.5,2,2.5,3,3.5 and 4 Gy.The apoptosis rates of all groups were analyzed by flow cytometry 24 h post-irradiation.The inhibition rates of cell proliferation were measured by the MTT assay.Results MTT assay showed that the Apo-2L treatment significantly inhibited cell proliferation(x2 =136.17,P ＜ 0.05).The apoptosis rates of the four groups were different significantly,and the apoptosis rate of radiation combined with drug group was significantly higher than the other three groups(x2 =78.02,P ＜0.05).Conclusions The Apo-2L could not only inhibit the proliferation but also promote radiation-induced apoptosis of adenocarcinoma H1975 cells.

Objective To evaluate the long-term effective rate,retention rate and tolerability of the ketogenic diet (KD) in pediatric drug-resistant epilepsies.Methods Data of 36 children who were treated in Department of Pediatrics,the Second Affiliated Hospital of Xi'an Jiaotong University from Nov.2011 to Dec.2013 and had continuous follow-up of at least 12 months after initiation of the KD were analyzed prospectively.Response was defined as 50％ seizure reduction.The effective rate,retention rate, outcome-predictive value of various clinical factors were also assessed.The causes of the patients withdrew from KD and side effects were recorded and analyzed.Results Thirty-six children(29 boys,7 girls; mean age of 2.84 years)were included.The effective rate was 50.0％,52.8％,47.2％ and 41.7％ at the 1,3,6,12 months;the retention rate respectively was 94.4％,91.2％,69.4％ and 52.8％.Seventeen cases withdrew from KD.Seven cases (41.2％)ceased KD becau~ of a lack of compliance,5 patients because of poor outcome,and 2 cases because of repeated infection.None of the age,disease duration,etiology and seizure type could be used as the predictor for the favourable treatment for outcome.The antiepileptic drugs before KD might be predicted the efficacy of the KD.The less amount of the antiepileptic drugs,the more opportunity of the KD might have to succeed.The side effects on the start-up period were drowsiness,week and digestive discomfort,hyperlipoidemia,hypoglycemia and hepatic dysfunction.The side effects on the maintenance period were digestive discomfort,susceptibility to infection,hyperlipoidemia,the deficiency of trace elements.Conclusions The KD is a safe and potentially effective method in treatment of refractory epilepsy patients who do not respond to customary medication therapies.

Objective To study the effect of cyclooxygenase-2 (COX-2)selective inhibitor Celecoxib on the expression of P-glycoprotein(P-gp)in the brain of rats with status epilepficus,in order to assess the therapeutic value of intractable epilepsy.Methods Sixty adult male SD rats were randomly divided into blank control group,the epilepsy model group and Celecoxib intervention group.The status epilepticus was induced in rats by injecting Lithium pilocarpine.Forty-eight rats were included in the experiment.There were 16 rats in each of the blank control group,epilepsy model group and Celecoxib intervention group,respectively.Immunohistochemical method and Western blot method were used to detect the expression of P-gp in experimental group in the frontal cortex and hippocampus.Results Immunohistochemistry result showed that the expression of P-gp was significantly higher in epilepsy model group than the blank control group,and the difference was statistically significant (P ＜ 0.01);The P-gp expression in the Celecoxib intervention group was lower than that in the epilepsy model group,and the difference was statistically significant (P ＜0.01).Western blot results suggested that the expression of P-gp could be found both in the frontal cortex and hippocampus in each group.Compared with the blank control group,the P-gp expression was significantly higher than that in the epilepsy model group,and the expression of the P-gp was lower after the Celecoxib intervention than that in the epilepsy model group,and the difference was statistically significant (P ＜ 0.05).Conclusions COX-2 inhibitor Celecoxib could decrease the expression of P-gp in brain tissue with status epilepticus,which may provide a new method for the treatment of intractable epilepsy.
