OBJECTIVE:To observe the clinical efficacy and safety of Qingkailing injection combined with naloxone in the ad-juvant treatment of chronic obstructive pulmonary disease (COPD) with pulmonary encephalopathy. METHODS:80 COPD pa-tients with pulmonary encephalopathy were randomly divided into control group and observation group. Control group was treated with conventional treatment,including bi-level noninvasive positive pressure ventilation,conventional oxygen inhalation,anti-infec-tion,resolving sputum and relieving asthma,etc;based on the treatment of control group,observation group was additionally treat-ed with Qingkailing injection 40-60 ml by intravenous infusion,30-40 drops/min,qd+Naloxone hydrochloride injection 0.8 mg by intravenous infusion,and then Naloxone hydrochloride injection 2 mg by microinfusion pump for continuous 24 h. After 3 d,the clinic data was observed,including clinical efficacy,and pO2,pCO2,pH,CO,CI,GCS coma score before and after treatment,av-erage hospitalization time,endotracheal intubation rate and incidence of adverse reactions. RESULTS:The total effective rate in ob-servation group was significantly higher than control group,average hospitalization time and incidence of adverse reactions were significantly lower than control group(P<0.05). After treatment,pO2,pH and GCS scores in 2 groups were significantly higher than before,observation group was higher than control group,pCO2 was significantly lower than before,observation group was lower than control group(P<0.05). There were no significant differences in the CO and CI before and after treatment and endotra-cheal intubation rate between 2 groups (P>0.05). CONCLUSIONS:Based on the conventional treatment,Qingkailing injection combined with naloxone has good efficacy and safety in the adjuvant treatment of COPD with pulmonary encephalopathy.

Objective The risk for coronary artery bypass surgery is reported to be increased with age and associated with diabetes. We examined the outcomes of coronary artery bypass grafting (CABG) in patients with diabetes who were older than 70 years of age and evaluate the effect of diabetes on CABG in those patients. Methods From March 2000 to March 2008, the data of 649 patients older than 70 years of age were collected retrospectively and divided into diabetic group or non-diabetic group based on pre-operative diagnosis. The blood glucose level of patients was maintained between 7.0 mmol/L ( 126mg/dl) and 10.0 mmoL/L ( 180 mg/dl) porioporatively. Stats 7.0 was used for statistical analysis. The t test and χ~2 test were used to determine the differences in the numerical variables and categorical variables respectively. Results No statistical differences were observed between the two groups in the baseline variables, such as age [ ( 74.78±3.67 ) years for diabetic group vs. ( 75.00±3.65 ) years for non-diabetic group, P = 0. 4877 ], female patients ( 34.76% vs. 29.22%, P =0. 1663 ), ejection fraction [ ( 57.02±10. 10 ) % vs. ( 58.49±10. 39 ) %, P = 0. 1004 ) ], myocardial infarction history (26.20% vs. 28.35%, P =0. 5795), though there were more left main diseases in the diabetic group (52.41% vs.26.41%, diabetic vs. non-diabetic, P = 0. 0000 ). The overall in-hospital mortality was 6.32% (8.02% in the diabetic group vs. 5.63% in the non-diabetic group, P = 0. 2571 ). The main causes of death were sudden respiratory and cardiac arrest,low cardiac output syndrome ( LCOS), malignant arrhythmia, respiratory failure, renal failure, central nervous system compli-cations, and multiple organ failure. Major post-operative complications were bleeding, atrial fibrillation, plural effusion and pulmonary infection. Post-operative variables, such as EF (0.59±0. 13 in the diabetic group vs. 0. 61±0.15 in the non-dia-betie group, P =0. 1807), re-revascularization due to bleeding (2. 14% vs. 4.76%, P = 0. 1232), blood transfusion (89.84% vs. 84.63%, P = 0.0820) and the administration of vasoactive agent (21.93% vs. 27.71%, P= 0. 1286),were found no significant difference between the two groups. Conclusion Conclusions The early outcomes of CABG in aged patients are acceptable. The surgical consequences in diabetic patients may be similar to those in non-diabetic patients.

The objectives of this study are to prepare resveratrol loaded mixed micelles composed of poloxamer 403 and poloxamer 407, and optimize the formulation in order to achieve higher drug solubility and sustained drug release. Firstly, a thin-film hydration method was utilized to prepare the micelles. By using drug-loading, encapsulation yield and particle size of the micelles as criteria, influence of three variables, namely poloxamer 407 mass fraction, amount of water and feeding of resveratrol, on the quality of the micelles was optimized with a central composite design method. Steady fluorescence measurement was carried out to evaluate the critical micelle concentration of the carriers. Micelle stability upon dilution with simulated gastric fluid and simulated intestinal fluid was investigated. The in vitro release of resveratrol from the mixed micelles was monitored by dialysis method. It was observed that the particle size of the optimized micelle formulation was 24 nm, with drug-loading 11.78%, and encapsulation yield 82.51%. The mixed micelles increased the solubility of resveratrol for about 197 times. Moreover, the mixed micelles had a low critical micelle concentration of 0.05 mg · mL(-1) in water and no apparent changes in particle size and drug content were observed upon micelles dilution, indicating improved kinetic stability. Resveratrol was released from the micelles in a controlled manner for over 20 h, and the release process can be well described by Higuchi equation. Therefore, resveratrol-loaded poloxamer 403/407 mixed micelles could improve the solubility of resveratrol significantly and sustained drug release behavior can be achieved.

Objective To investigate the clinical value of bile reinfusion combined with enteral nutrition before R0 resection of hilar cholangiocarcinoma.Methods The clinical data of 46 patients with hilar cholangiocarcinoma who underwent R0 resection at the Affiliated Drum Tower Hospital of Medical School of Nanjing University from January 2010 to January 2014 were analyzed retrospectively.The clinical data of 21 patients (the experimental group) who received bile reinfusion by preoperative percutaneous transhepatic cholangiography and drainage (PTCD) combined with enteral nutrition with nasojejunal tube were compared with 25 patients (the control group) who received neither PTCD nor enteral nutrition.The differences in the clinical indicators between the 2 groups were analyzed.Results In the experimental group,the levels of ALT,AKP,TBil and DBil decreased significantly after PTCD as compared with the original levels (t =4.433,4.547,5.648,4.681,P ＜ 0.05).The operation time and blood loss in the experimental group was reduced significantly when compared with the control group (t =-2.810,-2.047,P ＜ 0.05).The volume of postoperative albumin transfusion and the postoperative hospitalization in the experimental group was significantly reduced when compared with the control group (t =-3.083,t =-3.083,P ＜ 0.05).Conclusion Bile reinfusion combined with enteral nutrition facilitated the recovery of preoperative hepatic function in patients who underwent R0 resection of hilar cholangiocarcinoma,thus improving the safety of surgery and facilitated postoperative rehabilitation.

Objective To analyze our clinical results of head and neck reconstruction using microsur- gical free flap transfer techniques.Methods The free flap donor sites with long vascular pedicle and large diameter of vessel were routinely chosed,and chose receipt vessels with large diameter and proper position, and perform vessel ananstomosis under surgical loups instead of microscope.The un-buried free flap with a mo- nitoring window were harvest,and do double venous anastomoses in some flaps to ensure adequate venous out- flow.Results From May 1999 to March 2005,1066 consecutive free flap transfers were used to reconstruct head and neck defects.The overall success rate of free flap was 98.3%.The vessel thrombosis rate was 3.1%,and the flap salvage rate was 45.5%.Conclusion Head and neck reconstruetion using microsurgi- cal free flap transfer technique is safe and reliable,and good clinical results can be obtained.

Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.
