Objective To investigate the therapeutic effect of nasal endoscope surgery on chronic sinusitis and nasal polyps in geriatric patients.Methods A total of 132 geriatric patients with chronic sinusitis and nasalpolyps underwent nasal endoscope surgery in our hospital from Jun.2010 to Jun.2014,and the therapeutic effect was investigated.Results In the 132 cases,92 cases were cured (69.7％).Therapeutic effects were excellent in 33 cases (25.0％),and invalid in 7 cases (5.3％).The total effective rate was 94.7％.The total effective rate was 100.0％ in type Ⅰ,97.4％ in type Ⅱ and 84.8％ in type Ⅲ.The total effective rate was higher in type Ⅰ and Ⅱ than in type Ⅲ (x2=3.506 and 6.218,P=0.035 and 0.012).Local complications occurred in 10 cases (7.6％),including 1 case with nasolacrimal duct injury,2 cases with orbital hematoma,5 cases with nasal adhesion,1 case with surgical cavity hemorrhage and 1 case with sinus atresia.Conclusions The therapeutic effects of nasal endoscopesurgery on chronic sinusitis and nasalpolyps are good in geriatric patients,especially in treating chronic sinusitis and nasalpolyps of type Ⅰ and Ⅱ,and the postoperative complications are less,which is worth clinical application.

An introduction to the background of theSettlement by disease scoringpolicy in Yinchuan,concept and principles of the policy,and the medical insurance payment practice according to this policy.The authors compared the year-end settlement of medical insurance of a tertiary hospital in Yinchuan before the policy came into practice,expense growth per visit for inpatients of medical insurance,ratio of reimbursement,and ratio of complete out-of-pocket payment.These data were analyzed regarding the merits of such a policy and problems incurred,along with recommendations.

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.

Objective To investigate the clinical significance of myasthenia gravis (MG) associated autoantibodies.Methods Titin,ryanodine receptor (RyR)and acetylcholine receptor (AChR) antibodies were examined in the sera of 74 myasthenia gravies patients by ELISA.Results AChR,Titin, RyR antibodies were detected in 77.0% (57/74),39.2% (29/74) and 32.4% (24/74) of the MG patients,respectively.For thymoma MG,AChR,Titin and RyR antibodies were detected in 76.2% (16/21),71.4% (15/21) and 52.4% (11/21) respectively.For late onset MG,Titin and RyR antibodies were detected in 77.3% (17/22) and 50.0% (11/22) respectively.With respect to the modified Osserman classification,the positve rate for Titin and RyR antibodies is much higher in more severe patients (X~2= 16.094,P=0.001;X~2=11.226,P=0.011).Titin antibodies was significantly related with RyR antibodies (r=0.380,P=0.001).Conclusions Titin and RyR antibodies show high sensitivity for thymoma MG,and the combination of serological and radiological testing can increase both sensitivity and specificity in diagnosis of thymoma MG.The levels of the two antibodies may serve as important prognosis markers in MG.The induction of the immune response against Titin and RyR and the possible pathogenic effects of the two antibodies will be further studied.

By means of comparing biomasses of biodegradation fungi,Fusarium sp.HG-P-01 for ?-cypermethrin,a synthetic pyrethroid insecticide used widely in China,in five different media,the Czapek-Dox medium was selected as the best medium for mycelia growth.Furthermore,an experiment of central composite rotatable design(CCRD) was used to optimize the content of nutrient components.The optimal composition of C,N and P in media for HG-P-01 were 20.94 g/L,1.82 g/L and 1.66 g/L,respec-tively,in which an expectant or real rate of ?-cypermethrin-degradation got to 96.34% or 93.78% by HPLC for a concentration of 50 mg/L after 24 h treatment.The predicted value in degradation rate model was con-sistent with that from HPLC method.

Objective Laryngeal and upper esophageal foreign bodies are common diseases, we explored a new and simple method to remove these foreign bodies. Methods The clinical data of 177 patients with laryngeal and upper esophageal foreign bodies from June 2008 to January 2016 were analyzed retrospectively. We used two methods to treat these foreign bodies:130 foreign bodies were directly removed under video endoscopy;47 foreign bodies were removed with suspension laryngoscopy, and video endoscopy was used meanwhile. Result 177 laryngeal and upper esophageal foreign bodies were removed well, without severe complications like esophageal perforation or phyryngeal fistula. Conclusion Removing esophageal and laryngeal foreign bodies with video endoscopy is simple, safe and effective.

Objective To evaluate the effect of the application of fast track surgery theory, in endoscopic neurosurgery. Methods 198 patients of neuroendoscopic endonasal tranasphenoidal surgery for pituitary edenomas were divided into the experiment group and the control. The fast track surgery theory was applied in the experiment group while traditional methods in the control group. Psychological effect of preoperative bowel preparation, the postoperative recovery time of bowel function, analgesia effect, incidence of complications, postoperative nutrional state and hospital day were compared between the two groups. Results The experiment groups were less anxious than the control(P <0. 01 ). The postoperative recovery time of bowel function and Postoperative hospital day wore fewer than the control ( P < 0. 01). Postoperative pain was eased effectively. Condusions The fast track sugery theory can be applied in endoscopic neurosurgery to reduce the level of preoperative anxiety,increasing patient's comfort and improve the nutritional status,help recovery of patients.
