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.

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

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 effects of fraction of inspired oxygen (FiO2) and positive end-expiratory pressure (PEEP) on the gradient between arterial and end-tidal carbon dioxide (D(a-ET)CO2).Methods Sixty ASA Ⅰ or Ⅱ patients (body mass index ＜ 30 kg/m2),aged 25-50 yr,weighing 45-75 kg,scheduled for elective gynecological laparoscopic surgery,were randomized into A,B and C groups (n =20 each).The patients were mechanically ventilated with pure oxygen in group A,and with air and O2 (FiO2 =50％) in groups B (PEEP =0) and C (PEEP =5 cm H2O).PETCO2 was monitored during mechanically ventilation.Blood samples were obtained from the radial artery immediately after tracheal intubation (T1) and at 1 h of pneumoperitoneum (T2) for blood gas analysis.D(a-ET) CO2 and Qs/Qt were calculated.Results D(a-ET) CO2 and Qs/Qt were significantly lower at T2 in groups B and C than in group A (P ＜ 0.05).Compared with group B,D(a-ET)CO2 was significantly decreased at T2 (P ＜ 0.05),and no significant change was found in Qs/Qt in group C (P ＞ 0.05).Conclusion Decreased FiO2 and PEEP of 5 cm H2O can decrease D(a-ET)CO2 and increase the accuracy of PErCO2 for reflection of PaCO2,which is due to reduced intrapulmonary shunt.

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 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 explore the clinical efficacy of Naikan cognitive therapy(NCT) for alcohol dependent patients.Methods 64 cases of alcohol-dependent patients were randomly assigned to the study group (32 cases) and the control group (32 cases).The study group was treated with NCT for successive 7 days on the basis of taking original drugs; and the control group was only given the original drug therapy.The obsessive compulsive drinking scale (OCDS),self-report symptom inventory(SCL-90),nurses observation scale for inpatient evaluation(NOSIE) were administered to all subjects at pre-and post-treatment.Results ①After the treatments,the scores of OCDS in study group (49.51 ± 1.63) were lower than that in control group(53.92 ± 1.82),and the statistical difference had the significance (P ＜ 0.01).②After the treatments,the total scores and some factor scores of SCL-90 in study group were lower than in control group (t =-2.413,P =0.019 ; t =-2.033,P =0.047 ; t =-2.065,P =0.044 ; t =-2.038,0.046),and the difference was statistically significant.③After the treatments,in the study group,the scores of the total estimated factor and total positive factor(187.10 ± 18.80;78.51 ±12.22) were higher than in control group (175.51 ± 11.71 ; 68.22 ± 11.87),total negative factor score (15.55 ±9.46) were lower than in control group (20.51 ± 9.33),and the difference was statistically significant.Conclusion NCT can effectively inhibit alcohol craving,and reduce the drinking wine relevant questions.It can help to improve psychological symptoms in patients with alcohol dependence,especially depression and anxious symptoms.
