Objective To investigate the technical feasibility and oncological safety of EPMR for early esophageal cancer and precancerous lesions. Methods Clinicopathological data, procedure quality and complications of 70 patients with early esophageal cancer or precancerous lesions were retrospectively ana?lysed. The technical safety and feasibility were assessed, and the complications were investigated through postoperative surveillance. The results were compared with published data from two high?quality meta?analysis studies on ESD. Results In a total of 70 patients who underwent EPMR, 35?7%( 25/70) were diagnosed as having early esophageal cancer and 64?3%( 45/70) atypical hyperplasia. And tumor size greater than 2 cm was 78?6%(55/70). The mean EPMR time was(28?31±9?49) minutes. The R0 resection rate of EPMR was 88?6%(62/70) and no perforation occurred. The bleeding rate was 21?4%(15/70). The esoph?ageal stricture rate was 1?4%( 1/70) . The recurrence rate was 2?9%( 2/70) . Compared with published ESD data from the two studies, EPMR showed shorter procedure time, lower curative rate and lower rates of stric?ture and perforation, but slightly higher rates of bleeding and recurrence. Conclusion Both EPMR and ESD are feasible and effective for early esophageal cancer and precancerous lesions. The curative results of EPMR are similar to ESD, with shorter procedure time, but higher bleeding and recurrence rates.

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

Objective To evaluate the value of TruviewTM EVO2 optical laryngoscope for emergency endotracheal intubation in the clinical application.Methods Forty-four patients in need for emergency endotracheal intubation were randomly (random number) divided into two groups:the observation group (TruviewTM EVO2 optical laryngoscope for tracheal intubation,n =22) and the control group (ordinary laryngoscope for tracheal intubation,n =22).Parameters recordered included C/L (Cormack-Lehane)grade,the time taken for successful intubation,tracheal intubation times,lowerest SpO2 during the intubation and the incidences of complications after intubation.IDS (intubation difficulty scale) scores were calculated and the total effective rates were compared.Results The data showed that there were no significant differences in the duration of the successful endotracheal intubation attempts between the two groups,respectively (24.04 ±6.56) s and (21.97 ±8.92) s,P >0.05.The C/L grade with the observation group was 10∶ 9∶ 3∶0 (Ⅰ ∶ Ⅱ ∶ Ⅲ∶ Ⅳ),which was significantly better than that with the control group (3∶ 7∶ 9∶ 3,P <0.01).The tracheal intubation times of the observation group was 17∶ 5∶0 (one time∶ two times∶ three times),which was significantly better than that of the control group (9∶ 8∶ 5,P <0.01).The minimum of SpO2 in the observation group (97.31 ± 1.64)% was significantly higher than that in the control group (92.03 ± 5.39)%,(P < 0.01).The incidence of complications after intubation was lower in the observation group.The IDS score in the observation group (0.68 ± 0.38) was much lower than those in the control group (2.54 ± 1.49),(P < 0.01).In addition,the total effective rate of the observation group (86.36%) was significantly higer than that in the control group (45.45%),(P <0.01).Conclusions Using optical laryngoscope for emergency endotracheal intubation could facilitate the glottis exposure and reduce C/L grade effectively.It could lead to lower the incidence of complications and increase the success rate of tracheal intubation.

Objective To investigate the correlation of diastolic blood pressure (DBP) <70mm Hg and isolated systolic hypertension (ISH) with coronary atherosclerosis (CAS) and coronary heart disease (CHD) in elderly patients and to analyze the independent risk factors for low DBP.Methods A total of 246 elderly patients with untreated ISH who underwent coronary angiography were divided into the low DBP group (n=102) and the non-low DBP group (n=144) according to DBP level.All clinical and angiographic data were collected and the retrospective analysis was performed to assess the risk of CAS and CHD in patients with low DBP and to analyze the risk factors for low DBP.Results There were no significant differences in systolic pressure level between the low DBP group and the non low DBP group [(156.2±15.6) mmHgvs.(154.4±14.2) mmHg,t=0.93,P>0.05],while pulse pressure level was significantly higher in the low DBP group than in the non-lowDBPgroup [(91.3±±17.7) mmHgvs.(72.9±15.1) mm Hg,t=8.54,P<0.01].Stepwise logistic analysis showed that age,diabetes and smoking were independent risk factors for low DBP.After adjustment for age,gender and other common risk factors,low DBP was independently associated with CAS and CHD (OR =1.72 and 1.44,95% CI:1.082.72 and 1.04-1.99,respectively,both P< 0.05).Conclusions Low DBP is independently associated with CAS and CHD in elderly patients with untreated ISH.Age,diabetes and smoking are the independent risk factors for low DBP.

Serum bone alkaline phosphatase (BAP) , osteocalcin (OC) , C-telopeptides of type-1 collagen (CTx) , osteoprotegerin (OPG) levels, and bone mineral density (BMD) were evaluated in 62 hyperthyroid patients and 60 healthy subjects matched for sex and age. In hyperthyroid patients, the biochemical evaluations and bone density were performed before and after 6 months of methimazole ( MMI) treatment. Results showed that the BMD in lumbar spine L2 - L4, neck of femur, Ward's triangle and greater trochanter of patients before treatment were all significantly lower than those in healthy controls, and improved markedly after MMI treatment. The serum bone turnover parameters BAP, OC and CTx in patients before treatment were all significantly higher than those in control group, and were decreased markedly after treatment. The serum OPG level in patients with hyperthyroidism was significantly higher than that in healthy controls, and decreased markedly after treatment. The serum OPG levels were significantly correlated with bone turnover parameters ( BAP, OC, CTx) and BMD, which indicates that serum OPG level can reflect the abnormality of bone metabolism in patients with hyperthyroidism.
