1.Mechanisms of helicobacter pylori on the occurrence of gastric cancer
Journal of International Oncology 2015;(3):218-220
Helicobacter pylori is one of causes of gastric cancer. It can cause mucosal inflammation cytokines aggregation,gastric mucosal damage;and through a variety of ways to activate epithelial cells multiple oncogenic pathways,including phosphatidylinositol 3 kinase( PI3K)pathway,Wnt-β-catenin and epoxidized synthase-2(COX-2)-prostaglandin E2 antibody(PGE2)pathway,so as to change the gastric stem cell micro-environment and disrupt the gastric stem cell differentiation and proliferation,making the normal gastric stem cells evolved into cancer stem cells.

Chinese Journal of Biochemical Pharmaceutics 2017;37(8):180-182
Objective To investigate the therapeutic effect of inhaled budesonide suspension combined with psychological intervention on children with asthma. Methods 64 children with asthma were enrolled in our hospital from October 2015 to December 2016. They were divided into experimental group and control group, 32 cases in each group. The control group was treated with inhaled budesonide suspension.The experimental group was treated with inhalation with budesonide suspension combined with psychological intervention, the treatment efficiency and symptom improvement were compared and analyzed in the two groups. Results The effective rate of the experimental group was 96.87%, which was higher than that of the control group 84.37%, the difference was statistically significant (P<0.05). The symptoms of cough, wheezing, wheezing and dyspnea in the experimental group was obviously better than that in the control group, the difference was statistically significant (P<0.05). Conclusion The effect of inhalation with budesonide suspension combined with psychological intervention in the treatment of children with asthmais pbvious.It can effectively improve the clinical symptoms, and promote recovery of children.
4.Effect of low-intensity millimeter wave on the biophysics characteristics of erythroeyte
Chinese Journal of Medical Physics 2001;18(1):33-34,48
Low intensity millimeter(6mm,50GHz,100mW) wave was used to irradiate to 15 blood samples. The radiation time respectively were 15min、30min and 60min.Series rheological and biophysical parameters about the erythrocyte were systemically tested. There included viscosity of blood 、deformability and congregating ability of erythrocyte、hemolysical fragility 、anion transport in erythrocyte membranes and configuration of erythrocyte etc. From the point of biophysics, the biological effects of low intensity MMW to cells were investigated.

Objective To evaluate the curative effect of valsartan associated with low-dose amiodarone on the recurrence of atrial fibrillation (AF), the left atrial diameter (LAD), P wave dispersion (Pd) and the maximum P wave duration (Pmax) in patients with paroxysmal AF. Methods 76 patients with paroxysmal atrial fibrillation (PAF) were randomized to valsartan (test group) and placebo (placebo group), both associated with low-dose amiodarone, and were followed up for 18 months. The patients were asked to report any episode of symptomatic atrial fibrillation and to perform an ECG as early as possible. AF load, Pmax, Pd and LAD were measured before and at the 6th, 12th, and 18th month after the treatment. Results At least one ECG-documented episode of AF was reported in 16% of the patients in test group and in 41% in placebo group, the difference was significant (P

Objective To investigate angiographic manifestations and interventional treatment of renal arteriovenous fistulas. Methods Renal arterial angiographies were performed in 20 patients from multiple hospitals.These patients suffered from repeatedly intermittent hematuria,but ultrasound,KUB,IVU,CT and endoscopy could not contribute to the diagnosis.The angiographic manifestations and treating procedure were analyzed. Results All the 20 cases were diagnosed as renal arteriovenous fistula by means of angiography.According to the image manifestations,these cases were classified into three types:(1)deformed branches and shunt in 11 cases;(2)high discharge shunt without deformed banches in 4;(3)concealed shunt showed by superselective segmental artery angiography but negative by renal artery angiography in 5.All fistulas of the 20 cases were successfully embolized with different materials including gelfoam,sodium morrhuate,ethanol,PVA,TH-glue,coils,etc. Conclusions Superselective renal angiography and embolization are the most important and effective tools for diagnosis and treatment of renal arteriovenous fistula.

Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a hypotensive effect. The hypotensive effects of Taichong and Taixi were better than those of Taibai and the non-acupoint (P<0.05). The hypotensive effects of Taichong and Taixi were equal (P>0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

Objective:To investigate characteristics of masticatory movement path in young adults with AngleⅡ1 malocclusion.Meth-ods:1 5 youths with normal occlusion(group Ⅰ)and 1 5 with AngleⅡ1 malocclusion(group Ⅱ)were included.Mandibular movement paths of the incisal point of the incisor during unilateral-sided gum-chewing were recorded by the BioEGN mandibular kinesiography an-alyzer.Both maximal distances and directions (FH-opening/closing angles)in sagittal plane were analyzed.The statistic analyses were performed with SPSS 1 3.0 software.Results:Lateral distances of left masticatory movement path in Group I and Group II were (8.24 ±1 .48)mm and (6.58 ±2.49)mm,those of right(8.05 ±1 .05)mm and (6.42 ±2.47)mm,respectively(P <0.05).The aver-age of FH-opening/closing angle of masticatory movement path in Group I was higher than that in Group II at each level(P <0.05)ex-cept 0.5 mm point in the left masticatory movement path.Conclusion:Maximal lateral distance and FH-opening/closing angle of mas-ticatory path in young adults with AngleⅡ1 malocclusion are less than those with normal occlusion.
