Seven guaiane-type sesquiterpenoids, a new compound 6-formyl-5-isopropyl-3-hydroxymethyl-7-methyl-1H-indene (1), a new natural product 5-isopropyl-3, 7-dimethyl-1H-indene-1-one (2), along with five known compounds: guaiazulene (3), 4-formyl-7-isopropyl-10-methylazulene (4), sesquiterpene ketolactone (5), alismoxide (6) and guaia-1 (5), 6-diene (7), were isolated from gorgonian Muriceides collaris collected in South China Sea. Their structures were elucidated on the basis of extensive spectroscopic analysis [MS, IR, 1H NMR, 13C NMR (DEPT), HMQC, HMBC, NOESY] and by comparison of the spectral data with those of the literatures.

OBJECTIVETo investigate clinical effects of arthroscopy in the treatment of medial meniscal cyst.
METHODSFrom June 2011 to January 2013, 7 patients with medial meniscal cyst were treated with arthroscopy. There were 3 males and 4 females,ranging in age from 27 to 63 years old,with a mean age of (43.93±2.10) years old. The cysts have been discovered for 3 to 30 months,with a mean time of (10.6±1.3) months. All the patients complained of knee pain,especially in the medial joint gap. The Pisani sign, Caklin sign and medial McMurray sign were all positive. Preoperative MRI examination confirmed the diagnosis. Lysholm score changes and clinical efficacy were observed through a six-month follow-up.
RESULTSThe postoperative Lysholm scores were all significantly higher than the preoperative scores. According to Sarimo standard, 6 patients got an excellent result, and 1 good.
CONCLUSIONArthroscopic treatment of medial meniscal cyst has replaced the traditional method, which could retain the normal meniscus as much as possible and repair the meniscus injury simultaneously, as well as get a good curative effect and a good recovery of knee function. This method is worthy of clinical application.

Objective To evaluate the double-balloon enteroscopy(DBE) for obscure gastrointestinal bleeding(OGIB) and evaluate the health economics under the guidance of DBE for surgical treatment of obscure gastrointestinal bleeding.Methods A total of 114 patients,whose hemorrhage etiology could not be determined by conventional gastroscopy,enteroscopy and gastroenterography,underwent DBE.With pathological results as diagnostic criteria,the value of double-balloon enteroscopy for obscure gastrointestinal bleeding diagnosis was studied.Results The sensitivity,specificity and accuracy of DBE for OGIB were 85.86%,63.63%,81.57%,respectively.The positive likelihood ratio was 2.36 and the negative likelihood ratio was 0.22.The total days of hospitalization,hospital costs,cost of hospital drugs were lower in the DBE group than in the control group(27.2 ± 11.8 days VS 16.4 ±5.3 days,35 690.2 ±3 466.5 Yuan VS 19 409.3 ± 9 253.2 Yuan,17 805.8 ± 2 145.5 Yuan VS 9 133.0 ± 4 664.9 Yuan) (all P < 0.05).Conclusion DBE plays an important role in diagnosis of OGIB.It has significance in clinic,health economics,and social benefits.

Objective To investigate the effect of sedation on respiratory mechanic dynamics, intrapulmonary shunt fraction,oxygen metabolism in patients with mechanical ventilation.Method Sixty patients with mechanical ventilation were divided randomly into control group and sedation group.Propofal was administered to patients,whose ramsay scores were kept atⅢorⅣlevels,in sedation group while the equal amount of normal saline was given in control group.Mixed venous blood and arterial blood samples were taken for blood gas analysis in both groups before and at 2 hours after administration.Heart rate,blood pressure,breathing rate and airway resistance all were recorded at the same time.Results There were no significant differences in oxygenation index,blood pressure,blood lactic acid,total lung static compliance and intrapulmonary shunt fraction between two groups before and after administration.Heart rate,respiratory rate,oxygen uptake and airway resistance of patients in sedation group were lower than those in control group,and partial pressure of oxygen in mixed venous blood of patients in sedation group were higher than those in control group.These differences were statistically significant.Conclusions Sedation can decrease oxygen uptake and airway resistance of patients with mechanical ventilation.However,no alteration in the oxygenation index,total lung static compliance and intrapulmonic shunt ratio can be observed.

Objective To explore major risk factors for postoperative biliary tract infection associated with endoscopic retrograde cholangiography (ERC), and to evaluate endoscopic nasobiliary drainage (ENBD) for intervening the infection.Methods A total of 512 patients who underwent ERC at the First People's Hospital of Yunnan Province from January 2010 to June 2016 were enrolled and divided into group A and B randomly.Group A underwent ENBD after ERC while group B without.The incidence rates of biliary tract infection in different causes and lesions were compared between the two groups.Results Among the 512 patients, there were 276 cases in group A and 236 cases in group B.The overall postoperative biliary infection rate was 4.30%(22/512).Patients in group A showed a smaller chance of developing postoperative biliary tract infection than that in group B [1.09%(3/276) VS 8.05%(19/236), χ2=15.00, P=0.000].Malignant biliary obstruction was the most common cause (13.46%, 14/104) and the most common site was hepatic portal (13.43%, 9/67).Conclusion ENBD can ensure smooth drainage of bile duct therefore effectively prevent biliary tract infection after ERC, especially for patients with malignant biliary obstruction and hepatic portal lesion.
