Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumors of the diges-tive tract. Along with histology progress, the people have made the new progress regarding the mesenchy-moma understanding, also proposed the new viewpoint to its treatment, the therapy of GIST has changed from surgical resection alone to surgery after the application of tyrosine kinase inhibitor. The article reviews the therapy of GIST and proposes possible therapeutic regimen.

The early dynamic 18 F?FDG PET/CT can reflect perfusion, bio?distribution, uptake and excretion of 18 F?FDG in certain organs ( or lesions) in the early phase post injection. This imaging technique could be used to evaluate the organ ( or lesion) perfusion and to serve as a supplement for conventional 18 F?FDG PET/CT in the evaluation of glucose metabolism. This review summarizes the basic principle, imaging methods and clinical application of early dynamic 18 F?FDG PET/CT.

Therapies for malignant glioma include surgery,radiotherapy and chemotherapy.In recent years,the overall effective rate of temozolomide is better than other chemotherapy drugs,but partly patients have resistance to temozolomide.Angiogenesis inhibitors show promising activity,but it is expensive.Celecoxib has antiangiogenic activity,which has become a new option.

Objective To investigate the efficacy and safety of Wenxin Granule Combined with metoprolol in the treatment of arrhythmia in elderly patients with coronary heart disease.Methods84 cases of elderly patients with coronary heart disease arrhythmia treated in our hospital from April 2014 to May 2016, were randomly divided into observation group and control group, 42 cases in each group.The observation group was given the Wenxin Granule Combined with metoprolol treatment, the control group were treated with metoprolol,The changes of systolic status, the ischemic condition, hemodynamic changes and plasma viscosity were compared before and after treatment between the two groups, and the clinical effect after treatment were compared.ResultsAfter treatment, two groups of patients with atrial premature contraction, ventricular premature contractions and junctional premature contractions were decreased, the observation group was lower than the control group, the difference between the two groups was statistically significant (P<0.05);After treatment, two groups of patients with ischemic frequency were reduced, the observation group (5.45±1.12)times was lower than the control group (8.12±2.70)times, the difference between the two groups was statistically significant (P<0.05);After treatment, the two groups of patients with total ischemic time is shortened, the observation group (16.45±3.87)min shorter than the control group (22.45±4.89)min, the difference between the two groups was statistically significant (P<0.05);The total effective rate of the observation group was 92.85% higher than the control group (69.20%), the difference was statistically significant(P<0.05).ConclusionElderly patients with coronary heart disease arrhythmia patients with Wenxin granule combined with metoprolol treatment, can effectively improve the clinical symptoms of patients with significant effect.

Objective To analyze the cost-effectiveness of selective intraoperative laparoscopic cholangiography (LIOC) in the county level hospitals.Methods The medical costs and cost-effectiveness of 60 patients undergoing LIOC (group A) during laparoscopic cholecystectomy (LC) in 2014 and 52 patients undergoing LC (group B) only in 2013 at 3 county level hospitals were analyzed.Results The direct medical care costs of group A were less than that of group B significantly [(9 072 ± 1 282) Yuan vs.(10 941 ± 4 064) Yuan,t =-3.38,P =0.001],there were no significant different in indirect medical care costs between group A and group B[(2 039 ± 1 020) vs.(2 100 ± 1 172) Yuan,t =0.24,P =0.810].The cure rate was 100％ in two groups;however,the cost per patient in group A was less than that in group B [(11 111 ± 2 348)vs.(13 041 ± 5 118)Yuan].The direct medical care cost of the patients who needed additional treatment in group A was significantly less than that in group B [(10 828 ± 1 101)vs.(16 533 ±1 733)Yuan,t =-11.45,P =0.000].There were no significant different in direct operational costs between group A (LIOC + LC) groups and group B (LC) [(8 378 ± 326) vs.(8 225-± 363) Yuan,t =1.96,P =0.054].Conclusions Selective LIOC is a cost-effective procedure and should be recommended in county level hospitals in which magnetic resonance cholangiopancreatography is not available.

Objective To compare the therapeutic effect of aerobic exercise training of different intensity on hypertension. Methods Sixty hypertensive patients were randomly allocated to 2 groups and treated with aerobic exercise training at 20% or 60% of maximal intensity. Not only were the relevanl parameters of exercise capacity measured by the use of treadmill exercise test,but also was ambulatory blood pressure monitored and the quality of life recorded before and after the therapy. Results There was nc significant difference of the decrement in any parameter of ambulatory blood pressure between the two groups ( P>0. 05).There was a significant difference of the increment of general health, vitality, emotion and mentality between the two groups after treatment with group A better than group B(P <0. 05). Conclusions Aerobic exercise training at 20% and 60% of the maximal intensity has similar ambulatory blood pressure, but the quality of life is significantly better after aerobic exercise training at 20% of the maximal intensity.

Purpose Synchronous multiple primary esophageal carcinomas may be undetected by gastroscopy. This study aims to assess the role of 18F-fluorodeoxyglucose (18F-FDG) PET/CT in detecting synchronous multiple primary esophageal carcinomas. Materials and Methods Thirteen patients with synchronous multiple primary esophageal carcinoma who underwent gastroscopy and 18F-FDG PET/CT within two weeks before treatment were retrospectively analyzed. Results Gastroscopy and 18F-FDG PET/CT detected 22 and 29 esophageal carcinomatous foci respectively, and the difference was statistically significant (Z=-2.333, P<0.05). All the 29 esophageal carcinomatous foci showed high 18F-FDG uptake with a SUVmax ranging from 3.1 to 20.1 (mean, 10.7±5.7). 18F-FDG PET/CT also detected surrounding organ invasion in 3 patients, lymphatic metastasis in 10 patients and distant metastasis in 3 patients. Conclusion 18F-FDG PET/CT detects more esophageal carcinomatous foci compared with gastroscopy in patients with synchronous multiple primary esophageal carcinomas and also performs the staging diagnosis, which may help in improving clinical management and prognosis.

OBJECTIVE:To extract and purify organic acids with macroporous resins from Folium Isatidis.METHODS:Folium Isatidis was extracted with 70% aqueous ethanol(pH=2)by Soxhlet extraction.The process was optimized by employing orthogonal test design with the content of anthranilic acid as the index.RESULTS:The resin HPD100 had much better adsorption capacity and desorption ratio by using 3 BV 60% aqueous ethanol to extract organic acids in Folium Isatidis than other resins.The results showed that HPD100 possessed the better ecomic under the concentration of sample 0.18mg?mL-1,the condition of pH 3.5,and flowing rate of 2BV?h-1.CONCLUSION:Macroporous resin HPD100 may be value of isolating and purifying the organic acids from Folium Isatidis.

To find a component with the strongest anti-endotoxin effect from the four components (F021, F022, F023, and F024) of chloroform extract (F02) of Radix Isatidis, the protective effects of the five components on endotoxin-challenged mice and their effects on the production of TNFalpha and IL-6 by macrophages from the endotoxin-challenged mice were compared. It was found that the five components all had protective effects on endotoxin-challenged mice in terms of mortality. The mortalities of the mice challenged by 2.42 mg/kg endotoxin were 30 %, 50 %, 20 %, 50 % and 60 % after treatment with F02, F021, F022, F023, and F024. The 5 components all had inhibitory effects on the production of TNFalpha and IL-6 by macrophages from the mice. At a concentration of LPS of 50 ng/mL, the inhibitory rates of F02 , F021 1, F022, F023, and F024 for the production of TNFalpha and IL-6 were 76.54 %, 30.86 %, 78.60 %, 36.63 %, 2.06 % and 75.85 %, 18.45 %, 77.68 %, 24.41 %, 3.64% and at the dose of 100 ng/mL, the inhibitory rates were 49.65 Y, 16.86 %, 66.97 %, 13.39 %, 7.16 % and 59.78 %, 1.28 %, 61.86 %, 2.08 %, 1.44 %, respectively. It is concluded that the component F022 of Radix Isatidis has the strongest anti-endotoxin effect.
