    Objective To observe the change of myocardial autophagy during the isoprenaline-induced mice cardiac dysfunction. Methods The mice model of cardiac dysfunction was established by intraperitoneal injection of isoprenaline persistently for 4 weeks. Cardiac function was monitored by ultrasonic imaging system; hemodynamic changes were measured via tail-cuff method; autophagy-related protein expressions of LC3Ⅱ/LC3Ⅰand p62 were detected by Western blotting. Results After treatment with isoprenaline for 4 weeks, ejection fraction and fractional short reduced, interventricular septum increased, the ratio of early peak flow velocity and atrium peak flow velocity (E/A) tended to be elevated, suggesting declined cardiac function in model group compared with control group. Correspondingly, the heart rate and diastolic blood pressure decreased in model group compared with control group. After the injection of isoprenaline for 1 day and 3 days, the level of LC3Ⅱ/LC3Ⅰincreased and relative expression of p62 increased, but both returned to normal levels at the 4th week. Conclusion In the progress of isoprenaline-induced cardiac dysfunction, myocardial autophagy increased at an early stage, then returned to the normal level appearing to be a dynamic trend.

    Objective To investigate the role of advanced glycation end products (AGEs) in impairment of voltage-gated K+(Kv) channels in rat coronary vascular smooth muscle cells (VSMCs). Methods We isolated rat coronary VSMCs. The cells were incubated either in control medium, or medium with 100 μg/mL AGE-bovine serum albumin (AGE-BSA), or medium with 100 μg/mL AGE-BSA plus 100 μg/mL anti-receptor of AGEs immunoglobulin G (anti-RAGE IgG). Patch-clamp recording was used to assess the Kv currents. Western blotting and quantitative real-time PCR techniques were used to assess protein and mRNA expression of Kv 1.2 and Kv1.5. Results Incubation of VSMCs with AGE-BSA reduced Kv current density by 32.7% and decreased both protein and mRNA expression of Kv1.2 and Kv1.5 channels, whereas blocking AGE-BSA interacting with their receptors by preincubation with anti-RAGE IgG for 30 minutes prevented AGE-BSA-induced impairment of Kv channels.Conclusion AGEs impair Kv channels in coronary VSMCs by interacting with RAGE.

    Objective To observe the influence of different premature ventricular contractions (PVCs) burden on patients' heart structure and function, and its relevance to the left ventricular geometric pattern. Methods Totally 142 patients with PVCs were retrospectively analyzed. All the patients were divided into 3 groups by the burden of PVCs:the lower burden group (<10%, n=54), the medium burden group (10%-20%, n=55), the higher burden group (>20%, n=33). The difference and correlation between the heart structure, heart function and left ventricular geometric pattern in the 3 groups were analyzed; and the Logistic regression analyses were used to find out the risk factors of left ventricular hypertrophy. Results Compared with the higher burden group, the left atrial diameter(LAD), left ventricular outflow tract(LVOT), left ventricular internal dimension at end-diastole(LVIDD), left ventricular end-diastolic volume, left ventricular myocardial(LVM) mass and left ventricular myocardial mass index(LVMI) in the lower and medium groups were decreased, the LVEF in the lower and medium groups was increased (P<0.05). The PVCs burden was positively correlated with RVOT, LVOT, LVIDD, LVEDV, SV, LVM (P<0.05,); and was negatively correlated with LVEF (P<0.05,). With the increase of PVCs burden, the ratio of left ventricle normal geometry was decreased, and the ratio of eccentric hypertrophy geometry was increased. In a binary Logistic regression analysis, age, hypertension and PVCs burden were the risk factors of left ventricular hypertrophy in patients with PVCs. Conclusion The PVCs burden was closely related to the heart structure of the patients with PVCs. With the increase of PVCs burden, the left ventricular hypertrophy was aggravated gradually, the left ventricular systolic function was decreased, and the ratio of eccentric hypertrophy geometry was increased significantly. For patients with older age, hypertension and a heavy load of PVCs burden, doctors should monitor the cardiac function on early stage, and start the clinical intervention in time.

    Objective To explore the relationship between Helicobacter pylori (Hp) infection and the long-term outcome in patients with acute coronary syndrome (ACS) treated with drug-eluting stent (DES) implantation. Methods We retrospectively analyzed consecutive 326 patients who were treated with DES implantation from January 1, 2010 to December 31, 2012. Demographic data were collected and all patients underwent examination of high sensitivity C-reactive protein (hsCRP), homocysteine (HCY) and other biochemical indicators. All the patients were divided into three groups according to the result of 13C urea breath test. Group 1 had 176 patients without Hp infection; Group 2 had 75 patients with Hp infection with eradication therapy; and group 3, 75 patients with Hp infection without eradication therapy. We explored the correlations of Hp infection with major adverse cardiovascular event (MACE) and upper gastrointestinal bleeding (UGIB) after 5 years of follow-up using survival analysis. Results After 5 years of follow-up, we found that patients with Hp infection without therapy had more MACE and UGIB than the other two groups (P value is 0.009 and 0.000, respectively). Survival analysis showed that Hp infection was a predictor of MACE with a hazard ratio (HR) of 2.441, with 95% confidence interval (CI): 1.354-4.400, P=0.003 and UGIB with HR of 5.257, with 95% CI:2.572-10.745, P<0.001. Conclusion Patients after DES implantation with Hp infection had more MACE and UGIB after 5 years of follow-up. Hp eradication therapy maybe able to lower the rate of MACE and UGIB.

    Objective To investigate the effects and mechanisms of Loganin on tau phosphorylation.Methods Human neuroblastoma SK-N-SH cells were pre-incubated with Loganin (500 μmol/L,1 000 μmol/L, respectively) for 24 h, and then exposed to 10 μmol/L WT and 10 μmol/L GFX for 3 h after washing out Loganin. Western blotting was used to measure the phosphorylation level of tau protein at Thr205, Thr217, PHF-1 sites, glycogen synthase kinase 3β (GSK-3β), protein phosphatase 2A catalytic subunit C (PP2Ac) and the related proteins in the signaling pathway. Results WT/GFX inhibited the phosphorylation of GSK-3β-ser9, increased tau phosphorylation in SK-N-SH cells. Pre-incubation with Loganin significantly attenuated hyperphosphorylation of tau at Thr205,Thr217,PHF-1 sites in the model cells. Loganin did not reverse the decrease in p-GSK3β-ser9 induced by WT/GFX, suggesting that the effect of Loganin's inhibiting tau hyperphosphorylation may be independent of GSK-3β pathway. However, Loganin reduced the phosphorylation of PP2Ac at Tyr307, but not demethylation of PP2Ac at Leu309 in the WT/GFX-treated cells. Conclusion Loganin attenuated the hyperphosphorylation of tau at multiple sites by reducing the phosphorylation of PP2Ac in Alzheimer's disease-like cell model, independent of regulating GSK-3β.

Just one extra-ocular stage patient was confirmed to have bone marrow metastasis by bone marrow biopsy, the rest seven patients were negative. These eight patients were followed up till April 25th, 2016, the follow-up time was between 29 months to 54 months, six cases had stable disease, one died, one case was lost to follow up. Conclusion The rate of early bone marrow involvement in group D and group E of intraocular RB is extremely low, so bone marrow examination could not be done routinely. But when clinical stage is ambiguous, or who is an extra-ocular stage patient or there are imaging risk factors of intraocular RB, bone marrow examination and/or bone marrow biopsy should be done to make definite diagnosis. In addition, RB patients were young, bone marrow is in an active hyperplasia, the result of bone marrow examination will be affected by some factors, so bone marrow biopsy will be needed to clarify the nature of the juvenile cells.

    Objective The purpose of this study is to evaluate the technique and review the clinical effectiveness of partial arthroscopic repair of massive rotator cuff tears in elder patients. Methods Between January 2012 and June2014, 58 patients (27 men,31women) with a mean age of 57.5 years were undergone arthroscopic repair of massive rotator cuff tears. Patients were on the left side in 11 cases, and on the right side in 47 cases. All patients were evaluated from preoperatively to the final follow-up time using American Shoulder and Elbow Surgeons(ASES)score, Constant-Murley score, University of California,Los Angeles(UCLA)score of shoulder pain, active range of motion, active forward flexion and abduction strength. Then all data were analyzed statistically. Results All patients were operated successfully and got good healing and followed up at a mean time of 23.2 months (range from 18 months to 26 months). Before surgery ASES scores,constant scores,UCLA scores is 8.2±1.4,37.1±7.2,8.7±2.5, respectively. After surgery the scores are 28.5±4.5, 84.6±4.7, 28.4±4.5, respectively.The last follow-up compared with preoperative difference was statistically significant (P<0.05).Conclusion The therapeutic effect of arthroscopic repair of massive rotator cuff tears in elder patients showed satisfactory. And a good function of shoulder joint can be obtained.

    Objective To preliminarily study the effects of behavior intervention on patients with lower limb lymphedema(LLL) after gynecological carcinoma treatment. Methods Seventy-eight cases of patients with LLL after gynecological carcinoma treatment, were divided into 2 groups:control group and intervention group, to analyze the effects ofbehavior intervention on patients with LLL. Results Totally 88.5% of patients after gynecological carcinoma treatment have theunderstandingof LLL, while only 53.9% before treatment; the remission rate was 65% for patients with LLL accepted the behavior intervention, while the spontaneous remission rate was 39.5% for patients with LLL without behavior intervention, there had significant difference(P=0.024).Conclusion LLL is one of the common complications for patients after gynecological carcinoma treatment, and patients aregenerally lack of awareness of this complication, behavior intervention can effectively reduce the symptoms of LLL, promote the absorption of LLL, improve the life quality of patients, so behavior intervention should be used earlier in patients after gynecological carcinoma treatment to avoid or reduce the LLL.
