AIM:To compare the short-term and long-term curative effect between two implantation methods for treating refractory glaucoma.METHODS:A total of 150 patients with refractory glaucoma (150 eyes) were divided into Group A (treated by implantation with Ex-press glaucoma drainage device) and Group B (treated by implantation with Ahmed glaucoma valve) according to different implantation methods.Changes of intraocular pressure and anti-glaucoma drugs at different time points, the success rate of surgery, improvement of visual acuity and complications were compared between the two groups.RESULTS:The intraocular pressure of two groups at 1d, 1wk, 3, 6 and 12mo after surgery was significantly lower than that before surgery (P<0.05).The intraocular pressure of Group A at 3, 6 and 12mo after surgery was significantly lower than that of Group B, while anti-glaucoma drugs at 6 and 12mo after surgery were significantly fewer than those in Group B at the same time point (P<0.05).There were no significant differences between the two groups in 12-month success rate of operation, improvement rate of visual acuity and incidence of postoperative complications (P>0.05).CONCLUSION:The effects of implantation with Ex-press glaucoma drainage device are similar to those of implantation with Ahmed glaucoma valve in the treatment of refractory glaucoma.However, the intraocular pressure control effect of the former is better than the latter, and used anti-glaucoma drugs are fewer.

OBJECTIVE:To compare the effects of Qili qiangxin capsules and Compound danshen drop pills on related indexes of acute myocardial infarction(AMI)patients without reflow after percutaneous coronary intervention(PCI). METHODS:A total of 90 AMI patients without reflow after PCI were randomly divided into Compound danshen drop pills group (45 cases) and Qili qiangxin capsules group(45 case). Both groups were given Aspirin chewable tablets 300 mg and Clopidogrel sulfate tablets 300 mg before PCI. After surgery,both groups were given Aspirin chewable tablets 100 mg,once a day+simvastatin chewable tablets 10 mg,once a day. Based on it,Compound danshen drop pills group was given Compound danshen drop pills,10 pills,3 times a day. Qili qiangxin capsules group was given Qili qiangxin capsules,4 capsules,3 times a day. Both groups were treated for consec-utive 6 months. The blood flow classification of TIMI,LEVF,β1-AR,β2-AR,α1-AR,bleeding and the occurrence of major cardio-vascular events were observed in 2 groups before and after treatment. The occurrence of ADR was recorded. RESULTS:Bafore treatment,there was no statistical significance in the blood flow classification of TIMI,the levels of β1-AR,β2-AR and α1-AR be-tween 2 groups(P>0.05). After treatment,the case number of 0-2 degree blood flow classification of TIMI in 2 groups were signif-icantly lower than before treatment while the case number of 3 degree were significantly higer than before treatment;the levels ofβ1-AR,β2-AR and α1-AR were significantly lower than before treatment,while LEVF was significantly higher than before treatment;LEVF of Qili qiangxin capsules group was significantly higher than that of Compound danshen drop pills group,with statistical signifi-cance (P<0.05). There was statistical significance in the incidence of bleeding and major cardiovascular events between 2 groups (P>0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Qili qiangxin capsules is similar to Com-pound danshen drop pills in improving no-reflow efficacy and safety of AMI patients after PCI,but it is better than Compound dan-shen drop pill in improving cardiac function.

Objective To elucidate the effect of community nurse-led self-efficacy intervention on selfmanagement behaviors of hypertension in community elderly.Methods In this study,non-equivalent control group was designed,78 community elderly patients with hypertension were selected in the two community health service centers and divided into intervention group (38 cases) and control group (40 cases).The intervention group was treated with self-efficacy intervention for 3-month,and control group did not take any interventions.The “chronic disease self-management behavior measurement" (Stanford University research tool) and the measure of physical intervention study were used to valuate the effect of interference before and 3 months after intervention.Results Systolic blood pressure in intervention group was (5.11 ± 12.30) mm Hg and (0.33 ±4.64) mm Hg in control group,the difference was statistically significant ( t =2.248,P ＜ 0.05 ).BMI in intervention group was reduced by (0.43 ± 0.42 ) kg/m2,however,in control group was increased by ( 0.39 ±1.26) kg/m2,the difference has reached the statistical significance ( t =3.825,P ＜ 0.01 ).Self-efficacy,selfmanagement,health state in two groups were different ( P ＜ 0.01 ).Other factors in scale did not reach statistical significance in health service utility in two groups ( P ＞ 0.05 ).Conclusions The self-efficacy intervention can significantly enhance the community' s self-efficacy in elderly hypertensive patients,improve self-management behaviors and health,reduce health service use for a certain effect,but long-term effects need to be observed.

Objective To investigate the effect of berberine on inhibiting HT-29 human colon cancer cell proliferation induced by deoxycholic acid(DCA).Methods The berberine with concentration of 1,5,10 or 20?mol/L were added into the HT-29 human colon cancer cell culture media containing 200?mol/L DCA.The effects of berberine on cell proliferation were studied by the method of MTT.RT-PCR was applied to measure the expression of cyclooxygenase-2(COX-2)mRNA.Cellular immunochemical stain was applied to label COX- 2 protein expression.Concentration of prostaglandin E2(PGE2)was measured by radioimmunoassay. Results HT-29 cells were incubated with DCA for 6 h,COX2 expression of cells were increased prominent compared to controls(65.5%?5.6% vs.6.2%?1.1%).The level of PGE2 were increased(24.1 ng/L?1.4 ng/L vs.10.6 ng/L?0.8 ng/L).One?mol/L berberine reduced the proliferation rate of HT-29 in- duced by DCA over 6 h,the proliferation rate was 7.4?3.5%.Both COX-2 mRNA expression and the level of PGE2 were inhibited when the concentration of berberine was over 1?mol/L,and in a concentration-time dependent manner.Conclusions Berberine can inhibit the proliferation of HT-29 human colon cancer cell in- duced by DCA.Berberine can also suppress the expression of COX-2,and decrease the production of PGE2. These data provide new insights into the mechanism of its anti-cancer properties.

Objective To investigation the pathological characteristics of esophageal squamous cell carcinoma to provide reference criteria for delineating the target area in radiotherapy.Methods Fifty-two patients from the Fourth Hospital of HeBei Medical University underwent resection whom all had been proved to have esophageal squamous cell carcinoma before operation.Chest CT was scanned and transmitted to the 3- dimensional conformal planning system for radiotherapy by VRX-16 scanner.The lesion of esophageal carcinoma was delineated in the 3-dimensional rebuild CT image and the lesion volume was computed by digital rebuild program.Every surgically resected specimen was made into pathologic giant section.The actual size of the specimen was obtained by calculating the size under the microscope with the shrinkage ratio.Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration were observed in the giant section with a microscope and the order of such pathological characteristics were analysed statistically.Results 1.The tumor length by different method of preparation of operated specimens differed obviously.The longest was shown by CT. 2.Multicentric carcinomatous lesion was found in 15(29%)cases out of 52 patients.Proximal to the tumor,the mean distance between the multicentric carcinomatous lesion and the main lesion plus the length of the multicentric carcinomatous lesion was 3.02?1.45cm.Distal to the tumor,it was 2.60?2.44 cm.Severe dysplasia was found in 28 patients.Proximally,the mean distance between the severe dysplasia and the main lesion plus the length of the severe dysplasia was 2.45?1.30 cm.Distal to the tumor,it was 3.24?2.19 cm.Direct intramural infiltration was found in 41 patients,of which the mean length being 2.80?1.52 cm proximally and 2.02?1.51 cm distally. 3.Tumor thrombus was found in 6 patients and lymphoduct infiltration in 36 patients.Direct intramural infiltration was found at higher incidence in specimens complicated with lymphoduct infiltration(86%)and those complicated with tumor thrombus(91%).There were no apparent factors affecting severe dysplasia.The proximal distance to direct intra- mural infiltration was much longer than distally.Conclusions Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration may be observed in esophageal squamous cell carcinoma.Multicentric carcinomatous lesion and direct intramural infiltration are obviously correlated with lymphoduct infiltration.To cover 95% of the microscopic extension,a margin of 5.0 cm is needed proximal to the base of gross tumor volume,and 7.5 cm distal to it.To cover 90% of the microscopic extension,a margin of 4.5 cm is needed proximally,and 5.0 cm distally.

To explore the promotion of formative assessment for teaching, the surgery teaching and research section of Institute of Pediatric has carried out formative assessment in theory teaching of pediatric medicine pediatric surgery for seven-year program for two consecutive years , and the teaching effects and assessment results have been made detalled analysis. The results shows that for-mative assessment combining with summative assessment can guide the students to adjust learning method in time and improve teaching methods effectively. Compared with the pure summative evalua-tion, formative assessment has enhanced the students' learning initiative, and improved their abilityof learning and solving problems. Formative assessment can comprehensively measure the overall quality of students.
