Objective To evaluate the effectiveness of mouth gag which can inserted into lavage tube during gastric lavage. Methods The Sixty- six cases of acute poisoning patients with gastric lavage according to random number table method were randomly divided into two groups, 33 cases in each group. Observation group used the inserted mouth gag, and the control group used the metal ones. Results The observation group were lower than the control group at the time required to insert the lavage tube [(2.23±0.19)s to (3.26±0.30)s] and the incidence of complication rate [18.2%(6/33) to 45.5%(15/33)], the oral cavity bleeding [6.0%(2/33) to 30.3%(10/33)], lavage tube displacement [0(0/33)to 24.2%(8/33)], lavage tube twisting[0(0/33) to 24.2%(8/33)], the difference was statistically significant (P<0.01), while higher in the rate of successful intubation[100.0%(33/33)] to [54.5%(18/33)], the difference was statistically significant, χ2=19.4,P<0.01. Conclusions The application of the mouth gag which can insert into gastric lavage improved the successful intubation rate, saved the rescue time, reduced the complication and improved the nursing quality.

Objective To probe the application of superimposed flaps in hand surgery. Methods Form March 1998 to December 2003, we repaired 35 cases of skin defects with non trunk blood flaps and neurocutaneous vascular flaps. The area of flaps ranged from 1cm?1cm to 6cm?8cm. Results After operation, the flaps in 33 cases survived, but died in 2 cases due to unsuitable design. The follow ups ranging from 6 to 12 months showed that the quality and color of the survived flaps were similar to those of the normal tissue around. No swelling was found. Conclusion The superimposed flaps have reliable blood supply so that they are an ideal means to repair skin defects of hand.

Objective To investigate the value of contrast enhanced ultrasonography (CEUS) in the treatment of small hepatic malignancies with radiofrequency ablation(RFA). Methods Seventy patients with 104 pathologically proved malignant liver lesions treated by RFA (size 0.7 -2.7 cm) were divided into 2 groups including CEUS group and control group. In CEUS group,39 patients(54 lesions) were treated with RFA guided by CEUS, while in control group 31 patients (50 lesions) were guided by conventional ultrasonography. There was no significant difference between clinical data of the two groups. Results Seventeen tumors(among them,12 lesions were less than 1.5 cm in diameter) in 13 patients showed more clearly on CEUS image than on conventional ultrasonography image (31.5% ) in CEUS group. The tumor necrosis rate at one month after RFA was 100% in CEUS group,and 92% in control group ( P = 0. 034).The number of RFA sessions per tumor was 1.00± 0.00 in CEUS group,and 1.08 ± 0.27 in control group (P = 0.000). Local tumor progression rate was 0 in CEUS group and 4% in control group ( P = 0. 138)during the period of 8 - 52 months follow-up (average 21 months). Conclusions CEUS can not only improve the display of small hepatic malignancies but also provide precise guidance in contrast with conventional ultrasonography. Compared with control group, RFA of small hepatic malignancies guided by CEUS lower the number of RFA sessions, enhance the tumor necrosis rate, decrease post-RFA local progression and therefore it has extensive clinical value.

ObjectiveTo observe the effect of pioglitazone on the metabolism of glucose and lipid in patients with Impaired Glucose Regulation(IGR).Methods60 cases of IGR received conventional education on diabetes prevention,while the patients in intervention group(30 cases) accepted pioglitazone 15 mg once a day for 12 weeks.Blood pressure(BP),body weight,waist circumference,hip circumference were measured to calculate body mass index(BMI) and waist-hip ratio(WHR).The Fasting blood glucose(FBG),2 h postprandial blood glucose,glcosylated hemoglobin(GHb,HbA1C),fasting serum insulin(FINS),postprandial serum insulin(2hINS),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),hepatic function,renal function were determined before and 12 weeks after intervention.ResultsAfter intervention,BP,BMI,FBG,2hBG,FINS,2hINS,HbA1C,TC,TG,LDL-C had been decreased significantly in intervention group(P<0.05 or P<0.01).There were significant differences between intervention group and control group(P<0.05 or P<0.01) in all indexes except body weight,WHR,hepatic function,renal function.ConclusionPioglitazone can obviously improve the metabolism of glucose and lipid in patients with IGR.

Objective To evaluate the effect of injection of ozone (O3) through lateral recess for the treatment of radiculitis caused by lumbar disc herniation on the blood glucose in patients with diabetes mellitus.Methods Ninety-six patients with radiculitis caused by lumbar disc herniation involving 48 patients with diabetes mellitus and 48 patients without diabetes mellitus were enrolled in the study.The diabetic or non-diabetic patients were randomly divided into 2 groups ( n =24 each):non-diabetic patients-O3 group (group N-O3 ),non-diabetic patients-ghcocorticoid group (group N-GC),diabetic patients-O3 group (group D-O3 ),and diabetic patients-glucocorticoid group (group D-GC).In N-O3 and D-O3 groups,30 mg/L O3 10 ml was injected via the lateral recess.In N-GC and D-GC groups,compound betamethasone injection 3.5 mg was injected via the lateral recess.The blood glucose level was measured before treatment (T1),1 and 4 h after treatment (T3,4),and 1,3 and 7 days after treatment (T5-7).VAS score was recorded at T1,immediately after treatment (T2),and at T5-7.The patients' quality of life was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36 Health Survey) questionnaire at T1,7.The therapeutic effect was evaluated at T7.The side effects were recorded.Results Compared with the baseline value at T1,VAS scores were significantly decreased after treatment,while the MOS SF-36 Health Survey questionnaire scores for physical functioning,bodily pain,role emotional,and mental health in all groups,for general health in group N-GC,and for vitality in groups D-O3 and N-O3 were significantly increased at T7,and the blood glucose level was significantly increased at T4 in groups N-GC and D-O3,and at T3-7 in group D-GC ( P ＜ 0.05).There was no significant change in the blood glucose level before and after treatment in group N-O3.The blood glucose level was significantly higher in group N-GC than in group N-O3,and in group D-GC than in group D-O3 ( P ＜ 0.05).There were no significant differences in the excellent and good rates and all the MOS SF-36 Health Survey questionnaire scores among all groups.No side effects were found in the study.Conclusion Injection of ozone through lateral recess for treatment of radiculitis caused by lumbar disc herniation exerts no influence on the blood glucose level in patients with diabetes mellitus.

Aim To investigate the protective effect and the underline mechanisms of total flavonoids from Sorbus Tianschanica L leaf (TFST) against myocardial ischemia/reperfusion (I/R) injury.Methods The I/R injury model of rat isolated heart was prepared by improved Langendorff retrograde perfusion method.Following the treatment,the coronary blood flow levels (CF),left ventricular developed pressure (LVDP) and maximal rise/fall rate of left ventricular pressure (±dp/dt_(max)) were monitored as the myocardial function.The superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardial tissue were measured by the commercial kits. The in vitro anti-oxidative capacity of TFST was detected by the DPPH and lipid peroxidation reaction system.Results Compared with I/R injury group, pre-incubation with TFST (6.0 mg·L~(-1)) significantly improved the LVDP,±dp/dt_(max) and CF during reperfusion. TFST (6.0 mg·L~(-1)) treatment significantly increased the SOD activities and reduced the MDA levels in myocardium tissue.Moreover,TFST (from 6.25 to 100.0 mg·L~(-1)) scavenged the DPPH, hydroxyl radical and superoxide anion free radicals, and inhibited the lipid peroxidation reaction in a concentration-dependent way.Conclusions All the results demonstrate that TFST possesses the cardioprotective effect on ischemia/reperfusion injury.This efficacy may be due to its antioxidative activity.

Long noncoding RNA (lncRNA) is a class of RNA molecules that longer than 200 nucleotides.lncRNA is lack of functional open reading frames and has no protein coding ability.Recently, accumulating evidences indicate that lncRNA plays active roles in tumor carcinogenesis and progression.The aberrant expression of lncRNA is significantly correlated with the growth,metastasis,and therapy-resistance of digestive system tumors.Thus,lncRNA may be served as new targets for the diagnosis,treatment,and progno-sis of patients with digestive system tumors.
