Objective To explore the value and methods of echocardiographic application in percutaneous left atrial appendage(LAA) closure for stroke prevention in patients with nonvalvular atrial fibrillation.Methods 6 male patients with nonvalvular atrial fibrillation were enrolled for percutaneous LAA closure,the mean age was (68.7 ± 5.6) years old,the mean CHADS2 (congestive heart failure,hypertension,age≥75 years,diabetes mellitus,and prior stroke or transient ischemic attacks) score was 3.2 ± 1.0.Rheumatic valvular diseases were excluded by transthoracic eehocardiography(TTE) before closure procedure.Transesophageal echocardiography(TEE) was performed to guide the punctures of the atrial septum and then monitored the operation all through the closure procedure.Diameter of LAA orifice was measure by TEE to help choosing the closure device.Immediate results of closure and complications were inspected by TEE simultaneously.24 hours,7 days,3 months,6 months and 1 year follow-up were performed using TTE.Results All the 6 patients underwent LAA closure successfully.3 LAmbre(Lifetech Scientific,Shenzhen) devices and 3 Watchman(Boston Scientific,Natick,Massachusetts) devices were implanted respectively in the 6 patients.Mean diameter of the LAA orifice was (22.4 ± 3.3)mm,and mean size of the closure devices was (28.0 ± 2.9) mm.2 mm in width residual flow at the inferior edge of closure device existed in 1 ease.No complication was observed.Post-procedure 24 hours and 7 days post-procedure followup showed optimal results in all cases.Conclusions Implantation of both LAA closure devices can be performed with high success rates in patients with nonvalvula ratrial fibrillation,with high risk for stroke,and who either had contraindication or were not willing to accept oral antieoagulation.Echocardiography plays a core role all through the closure procedure and can make it safer and more efficient.

Objective To investigate the effects of Stichopus variegatus mucopolysaccharide on plasma nitric oxide (NO) and serum endothelin(ET) after angioplasty in rabbits. Methods 50 New Zealand rabbits were randomly divided into four groups: Stichopus group, simvastatin group, model group and normal group. Endothelium of iliac arteries in Stichopus group, simvastatin group and model group were denuded by balloon catheter and the rabbits were fed with 2%cholesterol, 3%lard and 3%yolk mixed forage for six weeks, and then, atherosclerotic stenosis was showed by iliac angiography.When transluminal balloon angioplasty was done, from then on the feeds was changed from high cholesterol to ordinary forage. Stichopus (0.5g?kg -1?d -1) and simvastatin (0.5mg?kg -1?d -1) were given by gastric canal. While NaCl solution (0.9%) was given in model group. All rabbits were fed in separate cages and free drinking. After four weeks since transluminal balloon angioplasty, blood was collected from carotid artery to measure the changes of concentrations of endothelin(ET) and nitric oxide(NO). Examination of pathology by optical and electron microscope were done at same time. Results After four weeks since transluminal angioplasty, the concentration of plasm ET in model group increased significantly compared with the normal group(114.86?24.89 ng?L -1 vs 75.62?9.68 ng?L -1) and serum NO decreased significantly(37.50? 12.79?mol?L -1 vs 106.37?18.01 ?mol?L -1).The concentration of plasm ET in model group was higher than that in the simvastatin groups and Stichopus groups(114.86?24.89 ng?L -1 , 81.08?14.71 ng?L -1 and 83.34?11.41 ng?L -1 ,respectively),and the concentration of serum NO decreased obviously(95.63?8.62 ?mol?L -1,98.80?9.06 ?mol?L -1 and 37.50?12.79 ?mol?L -1,respectively). Conclusion After iliac arterial TA the concentrations of plasm ET were increased and the serum NO were decreased, the endothelial function fell into disorder. The Stichopus variegatus mucopolysaccharide had the effects of improving the endothelial function after angioplasty in rabbits by adjustment of plasm ET and serum NO.

Metabolic syndrome (MS) and breast cancer are common diseases of women. Triple negative breast cancer (TNBCs) is one type of breast cancer, which is of much attention in recent years. Important components of MS include central obesity, high blood sugar, high triglycerides and low level of high-density lipoprotein (HDL-C), which increased the inci-dence risk of TNBCs. Common biomarkers of MS including insulin, adiponectin and leptin play an important role in the oc-currence and development of breast cancer, especially TNBCs. Insulin-like growth factor-IImRNA binding protein 3 (IMP3, an oncofetal protein) may be TNBCs’new invasive cancer biomarkers. In this paper, the research progress on the relation-ship between MS and TNBCs is reviewed.

OBJECTIVE: To investigate the possible effects of recruitment maneuver (RM) imposing on extravascular lung water (EVLW) in patients with acute respiratory distress syndrome (ARDS). METHODS: Twenty patients with ARDS who were eligible for the study were randomized to two groups, one group of which received regular therapy+RM (RM group), and to the other group only regular therapy was given (control group). Mechanical ventilation of all the patients was performed on the principles of lung protective ventilation. RM was carried out in bi-level positive airway passage (BIPAP) mode, and repeated every 8 hours per day until on the 7th day or before weaning of mechanical ventilation. The treatment was same between the two groups except RM. Baseline data and the influencing factors of EVLW were all recorded, which included everyday EVLW, extravascular lung water index (EVLWI) after RM, respiratory mechanics, oxygenation parameters, central venous pressure (CVP), plasma colloid osmotic pressure (COP), dosage of corticosteroid and adrenergic drugs, 24-hour net fluid balance. RESULTS: EVLW and EVLWI in RM and control group showed a tendency of decrease with passage of time, but the difference between both groups had no statistical significance (all P>0.05). The comparisons between the influencing factors of the groups, consisting of CVP, COP, noradrenalin and hydrocortisone, had no significant difference either (all P>0.05). Dopamine dosage in RM group on the 4th day was smaller than that of control group (P<0.05). Net fluid balance in RM group on the 7th day was negative, whereas it was positive in control group (P<0.05). Mean airway pressure [Pmean, RM group (18.8+/-3.2) cm H(2)O (1 cm H(2)O=0.098 kPa) vs. control group (16.6+/-3.9) cm H(2)O] and lung quasi-static compliance [Cstat, RM group (36.5+/-14.5) ml/cm H(2)O vs. control group (29.3+/-12.0) ml/cm H(2)O] in RM group were higher than those in control group (both P<0.05). Cstat on the 5th day was higher than that on the 2nd and 3rd day in RM group (both P<0.05). But oxygenation index (PaO(2)/FiO(2)) showed no distinct difference between the groups (all P>0.05). CONCLUSION: RM for the patients with ARDS can merely improve lung mechanics without obvious effect on EVLW. Neither of the influencing factors involved in the study has impact on emergence and clearance of EVLW.

OBJECTIVE To study the isolation status and antimicrobial resistance of nonfermenting Gram-negative bacilli collected from intensive care unit(ICU) of our hospital so as to instruct the rational clinical application of antibiotics.METHODS The antimicrobial resistance of nonfermenting Gram-negative bacilli isolates collected from patients in ICU from Jan 2003 to Dec 2007 was analyzed.Antimicrobial susceptibility of clinical isolates were tested by Kirby-Bauer method.RESULTS Total 384 nonfermenting Gram-negative bacilli isolates were collected in 5 years.The most common species were Acinetobacter baumannii(219),Pseudomonas aeruginosa(117) and Stenotrophomonas maltophilla(36).The antimicrobial resistance rate of nonfermenting Gram-negative bacterial to most antibiotics were much higher.The antimicrobial resistance rate of Acinetobacter spp to imipenem,cefoperazone/sulbactam and piperacillin/tazobactam was 3.7%,28.3% and 42.9%.But the resistance rate of Acinetobacter spp to imipenem was increased in recent 2 years(58.0%).The antimicrobial resistance rate of P.aeruginosa to cefoperazone/sulbactam was the lowest.That of imipenem-resistant P.aeruginosa to cefoperazone/sulbactam was 34.0%.S.maltophilla was relatively susceptible to ceftazidime,cefoperazone/sulbactam and piperacillin/tazobactam.CONCLUSIONS Nonfermenters Gram-negative bacilli are the important pathogens in ICU.Surveillance of their prevalence and drug resistance may provide evidences for rational antibiotic choices.

Objective: To investigate the clinical effect of entecavir combined with pegylated interferons in the patients with hepatitis B.Methods: Totally 72 patients with hepatitis B were randomly divided into the experimental group and the control group with 36 ones in each.The patients in the experimental group were treated with entecavir combined with pegylated interferons, and those in the control group were treated with entecavir.The clinical indicators in the two groups were detected and compared after the 24-week, 48-week and 6-month treatment.The adverse drug reactions in the two groups were recorded and compared.Results: After the 24-week treatment, the differences in the clinical indicators between the groups were not statistically significant (P >0.05).After the 48-week and 6-month treatment, the clinical indicators in the experimental group were obviously higher than those in the control group, and the differences were statistically significant (P <0.05).The difference in the adverse drug reactions in the two groups was not statistically significant (P >0.05).Conclusion: Compared with entecavir, pegylated interferon combined with entecavir in the treatment of hepatitis B shows better clinical effect and security, which is more worthy of clinical promotion.

Objective To establish adult rat auditory epithelial cell culture and try to find precursor cells of auditory hair cells in vitro. Methods With refinement of culture media and techniques, cochlear sensory epithelial cells of adult rat were cultured. Immunocytochemistry and Bromodeoxyuridine (BrdU)labeling were used to detect properties and mitotic status of cultured cells. Results The cultured auditory epithelial cells showed a large, flat epithelial morphotype and expressed F-actin and cytokeratin, a subset of cells generated from auditory epithelium were labeled by calretinin, a specific marker of early hair cell. Conclusion Adult rat auditory epithelium can be induced to generate hair cell-like cells by nature culture, this phenomenon suggests that progenitor cells may exist in rat cochlea and they may give birth to new hair cells. Whether these progenitor cells are tissue specific stem cells is still need more study.
