Objectives To observe the effect of Jianpi-Huayu decoction for preventing the patients from the recurrence of colonic adenoma after endoscopic mucosal resection. Methods A total of 60 patients with colonic adenoma who received endoscopic mucosal resection were divided randomly into the experimental group (taking Jianpi-Huayu decoction) and the controlled group (taking nothing as treatment), 30 patients in each group. Both groups were treated for 1 year. After 1 year, colonscopy was taken, and the number and size of colonic adenoma were recorded. The expression of COX-2, Ki67 in the colonic mucosa were detected the immunohistochemistry, and the negative rate of COX-2, Ki67 were also detected. Results After the treatment, the number (0.20 ± 0.48 vs. 1.67 ± 1.54, t=4.980) and size (0.23 ± 0.57 vs. 2.73 ± 2.80, t=4.788) of colonic adenoma in the experimental group were statistically lower than those in the ontrolled group (P<0.01);the expression of COX-2 (1.96 ± 1.27 vs. 3.64 ± 1.95, t=3.673) and Ki67 (2.04 ± 1.46 vs. 4.50 ± 1.73, t=5.558) in the the experimental group were statistically lower than those in the ontrolled group (P<0.01). The number of the paitents whose COX-2, Ki67 negative rates in the experimental group were 21 and 22, and the control group were 12(P=0.004) and 14 (P<0.001), which showed the significant difference between two groups. Conclusions The Jianpi-Huayu decoction could reduce recurrence of colonic adenoma after endoscopic mucosal resection, the mechanism was decreasing the expression of COX-2, Ki67 in colonic mucosa.

Objective To observe the influences of Yiqi-Humo recipe,A traditional Chinese prescription,on mucosa repair after endoscopic mucosal resction (EMR) and (or) endoscopic submucoal dissection (ESD).Methods 32 patients,who received EMR or ESD,were randomly recurited into a control group with 14 patients (omeprazole) and a experiment group with 18 patients (Yiqi-Humo recipe + omeprazole).Patients of both groups received treatment for a period of 4 weeks.Follow-up endoscopy was performed at 1 and 4 weeks after EMR or ESD,the index of symptom and mucosa signs were evaluated before and after the operation.Results At the 4 weeks after the procedure,the index of pain,pantothenic acid,anorexia,burning sensation in the experiment group [(0± 0.00)、(0± 0.00)、(2 ± 0.11)、(1 ± 0.06)] were lower than those in the control group [(12±0.86)、(6±0.43)、(15 ± 1.07)、(14± 1.00),P＜0.01].The index of hyperemia and edema of the experiment group [(3 ± 0.17)、(3 ± 0.17)] were less than those of the control group [(16± 1.14)、(15 ± 1.07),P＜ 0.01].Conclusion The prescription of Yiqi-Humo recipe promoted mucosa repair significantly after EMR or ESD.

Objective To observe the effectiveness of the percutaneous transluminal angioplasty (PTA) and percutaneous transluminal stenting (PTS) for central vein occlusion in maintenance hemodialysis patients.Methods From January 2010 to August 2015,a total of 42 patients with center vein occlusion of arteriovenous fistula were treated with maintenance hemodialysis,and the surgery and postoperative conditions,revascularization and improvement of vascular stenosis were observed.Results Among the 42 patients,38 cases were successfully carried out with PTA,and the patency rate was 90.5%(38/42).A total of 32 intravascular stents were placed in 30 patients whose vein stenosis were still greater than 30% after PTA.After surgery,the swelling of the patient receded rapidly and the internal fistula went back to normal.Conclusion PTA and PTS are effective methods for maintenance hemodialysis patients with central vein occlusion,and they could help protecting functional access in patients with autogenous fistulas with smaller wounds and faster effects.

Objective To discuss the effect of group counseling for medical students in reducing academic procrastination,and explore effective means to improve learning efficiency.Methods 24 students identified as voluntary research subjects were divided into the experimental group and the control group,male and female ratio was 1:1.The experimental group received counseling activities for eight times,the control group members did not receive any intervention.This thesis took use of Procrastination Assessment Scale-Students (PASS) as an evaluation tool in before and after test and tracing test,and did the significance test,as a quantitative analysis of this study.Results The quantitative study showed that the difference between the experimental group and the control group in pre-test was insignificant,indicating these research subjects belong to homogeneous research subjects; differences in pre-test and post-test of the experimental group were significantly greater than the differences of pre-test and post-test in the control group,indicating the group counseling producing an effect on learning procrastination.In order to verify the effect's continuity of the group psychological counseling,a tracking test was conducted on the members three months later.After three months,the tracking test scores of the experimental group and the control group were not significantly lower than the pre-test score.In tracking tests,the experimental group's scores were lower than before-test,indicating the effect of group psychological counseling was sustainable.Conclusions Group psychological counseling activities can reduce academic procrastination of medical school students and the group psychological counseling scheme has effectiveness and feasibility.

Objective To study the protective effect of estrogen against neuronal injury and the possible roles of alteration in the expression of bcl－ 2 following cerebral ischemia. Methods rats were ovariectomized.Brain ischemia was induced by left middle cerebral artery occlusion (MCAO) for 2 hours, and 22 hours of reperfusion,all animals were killed. The cerebral cortex sector histology was examined under light microscope (both qualitatively and quantitatively). The expression of bcl－ 2 was analyzed with immunohistochemical method. Results In estrogen－ treated groups, the density of normal neruons were significantly higher(P<0.05);Estrogen increased the expression of bcl-2(P<0.05).Conclusions The neuroprotective of estrogen was associated with up-regulation of bcl-2 in cerebral ischemia.

Objective To explore the protective effect and mechanism of exogenous hydrogen sulfide ( H2 S) on pressure ulcer rats with ischemia/reperfusion ( I/R) injury. Methods Forty SD rarts were randomly divided into 4 groups,namely normal control group,I/R model group,low-dose H2 S intervention group and high-dose H2 S interven-tion group. Each group had 10 animals. The low-and the high-dose H2 S intervention groups were injected intraperitone-ally 10 and 30μmol/kg of sodium hydrosulfide ( NaHS) for 1 week,respectively;however,the normal control group and I/R model group were treated with same volume 9 g/L saline. Then,the normal control group did not sustain any pres-sure,but other 3 groups were pressurized. After 3 circulations of ischemia/reperfusion,all rats were sacrificed,and path-ological changes in pressure ulcer rats were evaluated by HE staining. Serum H2 S contents were analyzed through meth-ylene spectrophotometric method. Serum levels of tumor necrosis factor-α(TNF-α),interleukin-6 (IL-6),intercellu-lar adhesion molecule -1 (ICAM-1),and myeloperoxidase (MPO) were detected by enzyme linked immunosorbent assay ( ELISA ) . The activities of malondialdehyde ( MDA ) , superoxide dismutase ( SOD ) , glutathione-peroxidase ( GSH-Px) and catalase ( CAT) in the homogenate of muscle were examined. Apoptotic index ( AI) was calculated by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling ( TUNEL) . The expressions of Bcl-2 and Bax in muscle tissue were evaluated by Western blot. Results In comparison with the normal control group,serum TNF-α, IL-6,ICAM-1 and MPO levels,MDA activity in the homogenate of muscles,AI and Bax expression level were in-creased (all P<0. 01),while serum H2S levels,the activities of SOD,GSH-Px and CAT as well as Bcl-2 expression levels were reduced in the I/R model group (all P<0. 01). Upon intervention therapy of low-or high-dose H2S,path-ological scores,serum TNF-α,IL-6,ICAM-1 and MPO levels,MDA activity in the homogenate of muscle,AI and Bax expression levels were gradually reduced while serum H2 S levels,the activities of SOD,GSH-Px and CAT and Bcl-2 expression levels were gradually enhanced when compared to those of the I/R model group (all P<0. 05,0. 01). Con-clusions Exogenous H2 S has better protection against pressure ulcer rats with I/R injury. The mechanism may be as-sociated with inhibition of inflammatory reaction and enhancement of antioxidative ability as well as reduction of apopto-sis.

To evaluate the feasibility of delivering NO through N_2O path in anesthesia machine,NO at 800 ppm was delivered through nitrous oxide path in anesthesia machine SIEMENS Ventilator 710 or NARKOMED 2B,to ventilate a test lung. The minute volume of ventilation (MV) was set from 2 to 6L/min, and NO concentration from 10 to 80 ppm.

Objective To analyze MRI findings of cesarean scar pregnancy (CSP). Methods The MR findings in 18 patients who were diagnosed as CSP by surgery from March 2010 to November 2011 were retrospectively analyzed,and comparison was made between the MRI findings and surgical results.Results All Gestational sacs (18) were clearly detected by MRI.Among the 18 cases,gestational sac presented as cystic mass with smooth margin located within the scar of uterine wall at the lower anterior uterus in 16 cases.In 2 of the 16 cases,gestational sac was found within the myometrium,whereas in the remaining 14 cases,gestational sac was found partially within the myometrium with extension into the uterine cavity.The anteior wall of isthmus uteri became thinner.In the remaining 2 of the 18 cases,gestational sac presented as irregular,multilobolated mass,growing deep inot the myometrium as well as into the uterinecavity. On T2WI,the mass showed heterogeneous signal intensity. A small amount of hemorrhage within the mass and uterine cavity could be seen on T1 WI. An enhancing solid component with a heterogeneous mass could be seen. All gestational sacs in 18 cases were located at or adjacent to the previous cesarean scar.In the area of cesarean scar,the signal of the uterine wall was disconnected,with focal indentation or thinning and the previous cesarean scar exhibited hypointensity on both T1WI and T2WI.Conclusion CSP has its unique findings on MRI,these specific features can provide useful information in the management of CSP.
