Background Selective laser trabeculoplasty (SLT) is a safe and effective therapy to the treatment of primary open angle glaucoma (POAG),and the clinical application is approved by American FDA.However,the relevant researching outcomes from several single-center study are in dispute owing to non-uniform approach in China.A muhicenter clinical trial is need to verify the effectiveness of SLT for Chinese POAG.Objective This study was to investigate the safety and efficacy of SLT in Chinese POAG patients.Methods A prospective,multicenter and self-controlled clinical trail was designed.Sixty-two eyes of 62 POAG patients with the age of ≥ 18 years were enrolled.Frequency SLT was performed around 360° angle using Lumenis Selecta DuetTM or Lumenis Selecta Ⅱ laser instrument,with the 100 non-overlapping spots,3 ns preset time,400 μm size of laser spot and 0.6 mJ energy.The operated eyes were followed-up for 6 months.The curative effects were checked including intraocular pressure (IOP),IOP-lowing value,number and percentage of IOP-lowing 20％ and 30％.The therapyrelated complications were recorded including the number of conjunctival congestion and cloudy of the anterior chamber.Results The preoperative IOP was (25.7±2.6) mmHg in the 62 eyes.The IOP was significantly lowed 1 day,2 weeks,4 weeks,3 months and 6 months after SLT in comparison with preoperative IOP (all at P＜0.001) with the lowest value of (16.5±4.5)mmHg in postoperative day 1.IOP was stable from 4 weeks to 6 months after operation.The mean lowing-value of IOP was 5.3-9.2 mmHg from 1 day through 6 months after SLT.The percentage of eyes 20％ drop in lOP was 83.9％,and that of 30％ drop was 58.1％ in postoperative day 1.In 6 months after SLT,percentages of eyes 20％ and 30％ drop in IOP were 56.5％ and 27.4％,respectively.Conclusions SLT is a safe and effective method of lowing IOP for POAG eyes in Chinese population.

Objective To compare the advantages and disadvantages of uniportal video-assisted thoracic surgery(uniportal-VATS)and three portal VATS in treatment of benign pulmonary diseases. Methods The clinical data of 66 patients with benign pulmonary disease treated by VAST from June 2015 to October 2016 were retrospec-tively analyzed. The patients were divided into two groups according to the specific operation. There were 32 patients (18 males and 14 females)in uniportal-VATS group. There were 34 patients(18 males and 16 females)in three portal VATS group. The operative time ,intraoperative blood loss ,thoracic drainage volume at 24 h after opera-tion,incision length,and the time of postoperative drainage of thoracic cavity,postoperative third day pain score and complication rate were compared between the two groups. Results The patients in the experimental and the control groups were successfully operated according to the scheduled protocol. No thoracotomy was performed. There was no statistical difference in the volume of blood loss,the volume of pleural drainage after 24 hours,the time of postoperative drainage of thoracic cavity ,the length of hospital stays and postoperative complications in uni-portal-VATS group and three portal VATS group(P>0.05). The pain score and postoperative third day pain score of the uniportal-VATS group was better than that of the three portal VATS group(P<0.05),but the operation time of the uniportal-VATS group was longer than that of the three portal VATS group(P<0.05). Conclusion Uniportal-VATS is safe and feasible for the treatment of benign lung diseases. It is more minimally invasive and beautiful than traditional three-hole thoracoscopic surgery. It is worthy of promotion and has broad prospects.

Objective To investigate the changes of perioperative right ventricular function after pulmonary resction. Methods 45 cases of pulmonary resection were divided into four groups.Group Ⅰwas wedge resection(n = 10), GroupⅡ was lobectomy(n = 19), Group Ⅲ was double lobectomy(n=7)and Group Ⅳ was pneumonectomy(n=9). The changes of CVP, PAMP, PEP/ET, Sa, VTIs, RVSP, Ea/Aa, and Tel were evaluated by traditional ultrasonic and tissue Doppler ultrasonic techniques at different time inter- vals (pre-operation, 5-7 days orland 1 month post-operation), Results Compared with the pre-operation CVP, the indexes of all groups have no significant changes post-operatively. Wedge resection didn' t obviously influence right cardiac after load and systolic function/diastolic function. No evidet changes detected in Tei pre-and post-operatively. However, the indexes (PAMP, RVSP and PEP/ET ratio) reflecting right cardiac afterload evidently increased at post-pneumonectomy or lobectomy group5- 7 days post-opera- tive. All these reflect the decrease of Tei, which was more obvious in pneumonectomy than in lobectomy group. Right cardiac after- load, systolic/diastolic function and Tel index recovered to pre-operative level 1 month post-operation in single lobectomy group. But the above indicators, especially the Tel, were still high in double lobectomy and pmeunonectomy groups 1 morth post-operation.Tei index is positively correlated with PAMP and is weakly correlated with PET/ET ratio and Ea/Aa ratio. Conclusion Pulmonary wedge resection doesn't evidently influence right cardiac function. However, right cardiac diastolic function evidently decreases temporarily at lobectomy group. The systolic function and diastolic funetions decrease after double-lobectomy and pneumonectomy and it's more evident in pneumonectomy group. Though the right cardiac afterloads of lobectomy, double lobectomy and pneumonectomy groupa all increase significantly post-operativlye, only the former recover to pre-operative level 1 month after surgery.

To establish a sensitive and specific method for simultaneous determination of gestodene, etonogestrel and ethinylestradiol in plasma by LC-MS/MS, plasma samples were extracted and derivatized before injection. An ESI ion source was used and operated in the positive ion mode with multiple reaction monitoring (MRM). Norgestrel was chosen as internal standard and performed on a C18 (100 mm x 2.1 mm, 5 microm) column. The concentrations of gestodene, etonogestrel and ethinylestradiol were measured, using step-gradient mobile phase and step-gradient flow rate. The method was validated over the concentration range of 0.1-20 ng x mL(-1) for gestodene and etonogestrel and 0.01-2 ng x mL(-1) for ethinylestradiol, and showed excellent linearity. The intra- and inter-assay accuracy and precision were below 10.0% and recovery was 93.6%-110.9% over the three concentration levels evaluated. The method was applied in pharmacokinetic study of the compound gestodene patch and the compound etonogestrel patch in rabbits. The LC-MS/MS method was selective, accurate and sensitive, especially the LOQ were 100 pg x mL(-1) for gestodene and etonogestrel and 10 pg x mL(-1) for ethinylestradiol. The method was successfully applied in pharmacokinetic study for contraceptives.

Objective To evaluate the effect of dexmedetomidine on left ventricular function in patients undergoing coronary artery bypass grafting (CABG) by transesophageal echocardiography (TEE).Methods The study was a prospective,randomized and placebo-control clinical trial.Eighty patients undergoing CABG with cardiopulmonary bypass (CPB) were divided into dexmedetomidine group (group D)and control group (group C) by random digits table method with 40 cases each.A loading dose of dexmedetomidine 0.5 μg/kg was injected intravenously 10 min after induction followed by infusion at 0.4 μ g/(kg· h) until the end of operation in group D,while equal volume of normal saline was given in group C.Left ventricular function was assessed by transesophageal echocardiography before the infusion of dexmedetomidine (T1),at the end of the infusion of loading dose (T2),before CPB (T3) and at the end of the operation (T4).Results Compared with those at T1,left ventricular ejection fraction and fractional area change decreased significantly [(58.0 ± 12.0)％,(60.0 ± 9.6)％ vs.(63.0 ± 8.6)％ and (46.0 ± 9.3)％,(48.0 ± 8.4)％ vs.(51.0 ± 6.7)％] (P ＜ 0.05 or ＜ 0.01),E/A ratio increased significantly (1.05 ± 0.27,1.07 ±0.31 vs.0.98 ±0.19)(P ＜0.05 or ＜0.01) and myocardial performance index (MPI) decreased significantly (0.46 ± 0.14,0.45 ± 0.12 vs.0.51 ± 0.14) (P ＜ 0.05) at T2 and T3 in group D,while stroke volume was not significantly changed (P＞ 0.05).Compared with that in group C,E/A ratio and rapid filling fraction in group D was significantly higher [1.06 ± 0.18 vs.0.97 ± 0.18,(62.0 ± 7.1)％ vs.(58.0 ± 7.3)％],and S/D ratio and MPI was significantly lower at T4(1.17 ± 0.21 vs.1.29 ± 0.22,0.43 ± 0.15 vs.0.50 ± 0.15),and there were significant differences (P ＜ 0.05).There was no difference in the parameters indicating left ventricular systolic function (P ＞ 0.05).Conclusions Dexmedetomidine restrains left ventricular systolic function in the patients undergoing CABG,but does not decrease the cardiac output,and improve relaxation dysfunction of left ventricular diastolic function.Global left ventricular function is improved by dexmedetomidine after CABG.
