The changes of PAF activity and the effects of anisodamine (654-2) were studied in the superior mesenteric artery occlusion (SMAO)shock in rabbits. The results showed that plasma PAF activity increased from 3.88?0.82 AU/ml before SM-AO to 9.71?1.26 AU/ml (P

BACKGROUND: Preplant diagnosis and rigorous implant strategy based on multislice spiral computed tomography (MSCT) imaging can improve success rate of mini-implants as anchorage. Effective application of imaging information in implant anchorage requires reliable tools and methods.OBJECTIVE: To investigate the accuracy of the radiographic and tunnel-type surgical templates assisting implant anchorage surgery and evaluate the clinical significance.METHODS: The transparent radiographic templates were made with occlusal rest to assist MSCT to scan two pigs' skulls locatively. After designed the implant anchorage angles in MSCT images accurately, we made the tunnel-type surgical template by angle data. A total of 32 miniscrews were implanted by surgical template, and the two pigs skulls were rescanned by MSCT. After dissected the pig alveolar process, the MSCT preoperative planning angles, the MSCT postoperative measurement angles and the measurement angles of anatomic bone samples were analyzed statistically. RESULT AND CONCLUSION: The 32 miniscrews were implanted successfully. They did not damage dental roots or surrounding important structures. Compared MSCT preoperative planning angles with MSCT postoperative measurement angles and anatomic bone samples measurement angles, there were no significant differences on axial sections or cross-sections and the r concordance correlations were very good. Results show that the radiographic and the tunnel-type surgical templates are accurate and reliable for operation and will help to improve the success rate of implant anchorage.

Objective To explore the nursing care of patients with Marfan syndrome accompanied with lens subluxation, and the clinical efficacy of phacoemusification combined with the implantation of modified capsular tension ring and foldable posterior chamber intraocular lens. Methods 11 patients (11 eyes) were performed the surgery. Uncorrected visual acuity preoperatively was (0.13±0.09). Best corrected visual acuity preoperatively was (0.20±0.17). Preoperative preparation, intraoperative observation and postoperative guidance were executed. The prognosis of these patients were observed. Results The operations were performed successfully. No intraoperative complications were founded. Mean uncorrected visual acuity at 2 year postoperatively was (0.60±0.28), and mean best corrected visual acuity was (0.70±0.28). Conclusions Careful preparation before surgery, close cooperation during surgery and the correct management after surgery were the important measures for the success of surgery.

Objective:To evaluate the efficacy and safety of micronised fenofibrate on lipid and uric acid metabolism in patients with hyperlipidemia.Methods: A total of 116 patients with hypertriglyceridemia and hyperuricemia received 200 mg micronised fenofibrate for 4 weeks.Physical and laboratory investigations of lipid profiles,serum uric acid,and 24 h urine uric acid,for adverse effects were assessed.Results:(1) Serum triglyceride(TG) was significantly reduced by 51%,whilst high density lipoprotein cholesterol(HDL-C) increased 24% after 4-week fenofibrate treatment.Moreover,serum total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) were reduced by 10% and 12%,respectively.(2) Serum uric acid levels were significantly reduced by 28.3% [from(462.8?73.5) ?mol/L to(320.1?83.0) ?mol/L] after fenofibrate treatment,independent of baseline uric acid le-vels.There was no difference in serum uric acid changes between male gender and female gender(29.8% and 25.1%,respectively).(3) Urine uric acid levels were increased by 36.0% [from(2 874.2?503.4) ?mol/L to(3 604.2?769.7) ?mol/L].The urine uric acid changes were 41.1% in male gender group and 33.4% in female gender group.The uric acid clearance/creatinin clearance ratio was increased in all cases after treatment.Conclusion: Micronised fenofibrate treatment could significantly improve lipid and uric acid metabolism in patients with hypertriglyceridemia and hyperuricemia,and is ge-nerally safe and well tolerated.The anti-hyperuricemic effect of fenofibrate is a result of increasing the urinary excertion of uric acid,independent of baseline level and gender.

Objective:To investigate the effect of acute mixed hyperlipidemia on acute myocardial infarct size and the potential mechanism.Methods: Fifty-three Sprague-Dawley(SD) rats were divided into three groups: the control group(n=15) was injected with 1.0 mL 0.9% sodium chloride,the low dose group(n=17) and high dose group(n=21) were injected with 0.5 mL and 1.0 mL 10% Triton WR-1339 solution respectively.Acute myocardial infarction was produced 24 hours after the injection.Serum lipid and the activity of lipoprotein-associated phospholipase A2(Lp-PLA2) were measured before and 24 hours after the injection.Rats were killed 24 hours after ligation and their hearts were excised to evaluate the myocardial infarct size.Results: Serum total cholesterol(TC) and trig1ycerides(TG) concentrations were(6.92?1.48) mmol/L and(11.76?2.76) mmol/L in the low dose group 24 hours after injection,(11.91?0.87) mmol/L and(33.97?5.85) mmol/L in the high dose group,and both increased significantly compared with the baseline.Also serum low density lipoprotein cholesterol(LDL-C) concentration increased(P0.05).Myocardial infarct size was significantly(P

OBJECTIVE To explore risk factors of cervical lymph node metastasis in cN0 papillary thyroid carcinoma. METHODS The clinical data of 537 patients with cN0 papillary thyroid carcinoma were analyzed retrospectively in Beijing Tongren hospital from Jan 2009 to Dec 2015. Patients' gender, age, multifocal lesion, carcinoma complicated with Hashimoto's thyroiditis, capsule breakthrough and tumor size were counted. RESULTS The lymph node metastasis rate of 537 patients with cN0 papillary thyroid carcinoma was 30.9%(166/537). The incidences of lymph node involvement were 24.95%(166/537) at only level VI, 5.21%(28/537) at level VI plus lateral part of neck and 0.74%(4/537) at only skip metastasis, respectively. Chi square test and multivariate logistic regression analysis showed that cervical lymph node metastasis was statistically associated with male, age<45 years, capsule breakthrough and tumor diameter>1 cm (P<0.05). After the operation, there were 17 patients with temporary hoarseness, accompanied with 1 loss to follow-up and 1 failure to return to normal after 1.5 years. There were 61 patients with temporary hypocalcemia, 2 patients failed to follow-up and 2 patients with calcium supplements after respective 1.5 and 4 years. CONCLUSION To stratify the risk of patients with cN0 papillary thyroid carcinoma, male, age<45 years, capsule breakthrough and tumor diameter>1 cm are risk factors for cervical lymph node metastasis. And we suggest that prophylactic central lymph node dissection may be appropriate.

Mitochondria play a central role in the regulation of cellular energy metabolism, bio-synthesis and cell death. Dysfunction of mitochondria can lead to many diseases. Mitochondrial proteomics provides important theoretical foundation for a systematic understanding of the biological functions of mitochondria, studying the mechanisms of mitochondria-related diseases, and promoting the research and development of mitochondria-targeting drugs. The methodologies, recent technology development, and characteristics and applications of mitochondrial proteomics were reviewed and the challenges and prospects were also discussed.
