Objective To explore clinical effect and safety of amiodarone combined with bisoprolol in patients with congestive heart failure and ventricular arrhythmia. Methods Selected 100 cases with congestive heart failure and ventricular arrhythmia in our hospital from January 2011 to April 2017 as research objectives and divided them into two groups randomly with 50 cases in each group. Provided amiodarone to control group and provided amiodarone combined with bisoprolol to observation group. Compared two groups' arrhythmia and cardiac function, heart rate, ejection fraction, QT time (QTc) corrected for heart rate before and after treatment as well as adverse events. Results Observation group's effective rate of arrhythmia treatment and the effective rate of cardiac function were 94.00％, 96.00％, those were significant higher than control group's 70.00％, 78.00％ (P<0.05). Two groups' heart rate and ejection fraction score after 3 month treatment were significant higher than those before treatment (P<0.05), and observation group's improvement was more significant (P<0.05). Observation group's QTc was significantly prolonged after 3 months of treatment (P<0.05), but control group's QTc did not change significantly. There was no significant difference in the incidence of adverse reactions between the two groups. Results Amiodarone combined with bisoprolol has significant clinical effect on patients with congestive heart failure and ventricular arrhythmia. It is safe and worthy to be promoted clinically.

OBJECTIVETo investigate whether bortezomib can enhance the sensitivity of human prostate cancer (PCa) cells to natural killer (NK) cell-mediated cytotoxicity, and whether it produces the same effect on different PCa cell lines.

METHODSWe treated androgen-dependent PCa LNCaP cells and androgen-independent PCa DU145 cells with bortezomib at the concentrations of 0, 5, 10, 15, 20 and 25 nmol/L for 24, 48 and 72 hours, and then detected the proliferation and apoptosis of the tumor cells by CCK-8 and Annexin V/PI, respectively.

RESULTSThe proliferation rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (82.79 +/-2.04)%, (73.59+/- 2.95)% and (74.16+/- 6. 16)% at 48 hours and (71.24+/- 5.30)%, (51.20+/- 2.91)% and (38.02+/- 2.67)% at 72 hours, and those of the LNCaP cells were (77.04+/- 7.74)% , (42.61 +/- 6.62)% and (23.85 +/-6.04)% at 48 hours and (36.45 +/-7.02)%, (14.94 +/-5.76)% and (11.65 +/-5. 87)% at 72 hours, both significantly inhibited as compared with the control group (P <0.05). At 24 hours, the apoptosis rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (14.41 +/- 1.32)% , (16.13 +/- 1.55)% and (14.48 +/- 1.42)% , and those of the LNCaP cells treated with 20 and 25 nmol/L bortezomib were (12.77 +/- 1.28)% and (14. 84 +/- 1.65)% , significantly higher than those of the control group (P <0.05) , and the DU145 cells showed an even higher sensitivity to bortezomib than the LNCaP cells. Bortezomib failed to sensitize these two cell lines to NK cell-mediated cytotoxicity in short-term assay, while long-term assay manifested that the apoptosis rates of DU145 and LNCaP cells after treated with 20 nmol/L bortezomib + NK cells were (41.83 +/- 5.06)% and (30.31 +/- 3.62)% , respectively, significantly higher

CONCLUSIONBortezomib enhances the sensitivity of than those after treated with either bortezomib or NK cells alone (P <0.05). PCa cells to NK cell-mediated cytotoxicity and adds to the effect of current cancer therapies, and it is more efficacious for androgen-independent prostate cancer.

Objective To investigate the relationship between ambulatory arterial stiffness index (AASI) derived from blood pressure monitoring and early signs of renal damage in patients with primary hypertension． Methods 74 primary hypertensive outpatients were divided into two groups according to their AASI values: normal AASI group (AASI≤0.51, n=40) and high AASI group (AASI>0.51, n=32). The urinary micro-albumin, glomerular filtration rates (GFR) were measured and compared. The relationship between AASI and micro-albumin, GFR were tested with Pearson correlation and multiple Logistic regression. Results Compared with those in the normal AASI group, the patients in high AASI group showed a higher level of urinary microalbumin (P<0.05) and a reduction in GFR (P<0.01). AASI was positively correlated with urinary microalbumin （r=0.32, P<0.001）, and negatively correlated with GFR （r=0.44, P<0.001）. After adjusting the potentially confounding variables, the odd ratio (OR) of AASI to renal damage was 2.18 （P=0.008，95%CI：1.76～4.34）. Conclusion The increase of AASI is associated with early signs of renal damage in patients with primary hypertension.

Objective · To explore the relationship of adipose chemerin and its receptor chemerinR gene expression to obesity and type 2 diabetes mellitus. Methods · Twenty-four patients undergoing elective abdominal surgery were enrolled, and were divided into normal glucose regulation-normal weight group (NGR-NW), normal glucose regulation-overweight/obesity group (NGR-OW/OB), and type 2 diabetic overweight/obesity group (T2DMOW/OB) according to the body mass index (BMI). The levels of chemerin and chemerinR mRNA were detected by reverse transcription PCR (RT-PCR).Results · Compare to the NGR-NW group, the chemerin mRNA levels of abdominal subcutaneous and omental fat were significantly increased in the NGR-OW/OB and T2DM-OW/OB group (P<0.05). Correlation analysis showed that the chemerin mRNA levels of abdominal omental fat were positively correlated with BMI, fasting insulin (FINS), triglyceride and serum chemerin (r=0.577, r=0.561, r=0.472, r=0.623, P<0.05 for all). The chemerin mRNA levels of abdominal subcutaneous fat showed significant positive correlation with BMI, FINS and serum chemerin (r=0.692, r=0.513, r=0.497, P<0.05 for all). Conclusion · The chemerin mRNA levels of abdominal subcutaneous and omental fat were positively correlated with BMI, FINS and serum chemerin, suggesting that the chemerin gene may play a crucial role in the pathophysiological mechanism of obesity and type 2 diabetes.

BACKGROUND: The curative effect is satisfactory for adult patients with spasticity of lower limbs treated with selective posterior rhizotomy and peripheral nerve micro diminution. But how to improve the strength of relevant muscle is the key factor to accelerate recovery of motor function during rehabilitation training.OBJECTIVE: To observe the effect of muscle stimulating instrument on the recovery of muscle strength and the improvement of motor function of adults with spasticity of lower limbs during rehabilitation training.DESIGN: Case analysis.SETTING: Department of Neurosurgery, China-Japan Friendship Hospital of Beijing Ministry of Public Health.PARTICIPANTS: Totally 49 adults with spasticity of lower limbs were selected from Department of Neurosurgery, China-Japan Friendship Hospital of Beijing Ministry of Public Health from January 2000 to May 2002.There were 37 males and 12 females aged from 19-48 years. Totally 21patients treated with muscle stimulating instrument were determined as treatment group and other 28 patients were determined as control group during rehabilitation training.METHODS: One day after operation, conventional rehabilitation training was performed on patients in the treatment group and the control group.Patients in the treatment group were also treated with muscle stimulating instrument three times a day with each for 30 minutes for totally 7 days as a course. There was a three-day interval between treating courses and the rehabilitative time lasted for 6 months. Before rehabilitation training, indexes of patients in the two groups, such as ankle extension, knee flexion and muscle strength of thigh adductor, were recorded and the improvement of muscle strength after 3 and 6 months was followed up.MAIN OUTCOME MEASURES: Average strength of relevant muscle before and after 3-month and 6-month rehabilitation training.RESULTS:Totally 49 patients entered the final analysis.①After 3-month and 6-month treatment, indexes of ankle extension, knee flexion and muscle strength of thigh adductor were increased at various degrees.②During 3-month and 6-month treatment,indexes of ankle extension,knee flexion and muscle strength of thigh adductor in the treatment group were obviously higher than those in the control group [3-month treatment:(4.2±0.8), (3.7±0.7) degrees; (4.3±0.7), (3.8±0.7) degrees; (4.0±0.7), (3.5±0.5)degrees; 6-month treatment: (4.5±0.6), (3.9±0.7) degrees; (4.6±0.7), (4.0±0.5)degrees; (4.4±0.7), (4.0±0.6) degrees, (P ＜ 0.05 or P ＜ 0.01)].CONCLUSION: The combination of rehabilitation training and muscle stimulating instrument can accelerate the recovery of muscle strength and motor function in adults with spasticity of lower limbs after microsurgical treatment.

AIM:To explore the effect of recombined sICAM-1 on the adhesion of leukocyte to pulmonary microvascular endothelial cell. METHODS:Primary cultured rat pulmonary microvascular endothelial cells were used in this experiment. Leukocyte was labeled with 99　Tm-HMPAO.The effects of different dose of sICAM-1, CA7 and dimeric form of sICAM-1 (sICAM-1*CA7)were tested separately in cell adhesion .RESULTS:sICAM-1 and CA7 could not inhibit cell adhesion even at the concentration of 100 mg/L,while sICAM-1*CA7 at concentrations of 20 mg/L and 40 mg/L could inhibit 42% and 50% of cell adhesion respectively (P＜0.05). CONCLUSION:sICAM-1 has poor inhibitory effect on cell adhesion, probably due to monomeric form.

Bone morphogenetic proteins (BMPs) were first studied as growth factors or morphogens of the transforming growth factor-beta super family. These growth molecules, originally associated with bone and cartilage development, are now known to play important roles in morphogenesis and homeostasis in many other tissues. Recently, signiifcant contributions of BMPs, their receptors, and interacting molecules have been linked to carcinogenesis and tumor progression. BMPs can sometimes play a role as a tumor suppressor. This article explains the composition and biological characteristics of BMPs, and investigates their new roles in the pathogenesis of cancer.
