Objective To evaluate the efficiency and safety of non- nasogastric tube on fast-track surgery patients with colorectal cancer. Methods We searched PubMed, CBM, Cochrane Library, CNKI, Wanfang and Vip data. Controlled trials that met the criteria were selected. All reports were collected and analyzed by RevMan5.3. Results 8 reports were enrolled. The non-nasogastric tube group had a shorter anus exhausting time and lower morbidity of pulmonary and throat complications , and it also had a shorter postoperative length of hospital stays. Significant differences were found between the non-nasogastric tube group and the control group (P< 0.01). There are no significant difference in the morbidity of gastrointestinal complications (P > 0.05). Conclusion Current evidence shows that non-nasgastric tubes are recommended for the patients with colorectal cancer surgery.

Objective To investgate the proper perioperative management of Debakey Ⅰ aortic dissection by new type of three branches aortic arch covered stent graft implantation. Methods A total of 56cases with Debakey Ⅰ aortic dissection were enrolled into the study and operated by new type of three branches aortic arch covered stent graft implantation from July 2009 to August 2010. Results The cardiopulmonary bypass time during the operation was 90. 0 -248.0 min( median time 180. 6 ains) ,aortic cross clamp time was 69. 0 - 180. 0 min(median time 108. 2 mins) ,circulation arrest time was 17.0 -37.0 min ( median time 22. 6mins) ,the time using reathing apparatus was 16.0 -260.0 hours (median time 42. 8 hours),ICU residence time was 3.0 -23. 0 days( median time 6. 6 days). Fifty-four patients got well and were discharged. One patient died of multi-organ failure postoperatively and another died of large area of acute myocardial infarction. After the operation, six cases had acute renal failure, five cases had tracheotomy, three cases had reoperation for hemorrhage,one case had retardant pericardial tamponade, one case suffered from spinal cord injury, one had cerebral hemorrhage, and five cases had refractory arrhythmias. Conclusion The new type of three branches aortic arch covered stent graft simplified the procedures of aortic arch operation and lowered the operative risk in treatment of Debakey Ⅰ aortic dissection. Properly control of blood pressure and pain before surgery, shorten circulatory arrest time, maintain good organ perfusion seem to be the key points to improve the prognosis in patients with aortic dissection.

Objective To optimize the best techniques of preparing baicalin gelatin microspheres with orthogonal experimental design.Methods Baicalin gelatin microspheres were prepared by emulsion chemical-cross linking method with degradable gelatin as carrier,liquid paraffin as oil phase,Span-80 as emulsifier.The particle size,containing efficiency of microspheres were determined and technique reproducibility was studied.Results Microspheres with good shape,smooth surface and narrow size distribution were prepared.The average diameter of microspheres was 27.47 ?m,the loading amount of medicine was 8.18% and encapsulation efficiency was 70.21%.Conclusion The preparation procedure established was stable and practical.

Objective To set up the determining method of quercetinum in Kuding Cha of Ligustrum by HPLC. Method Hypersil ODS2 chromatographic column (4.6 mm?250 mm, 5 ?m) was adopted. Methanol 0.4% phosphoric acid (47∶53) was used as mobile phase, the flow rate was 1 mL/min, and the detecting wavelength was 360 nm. Result The linear range of quercetinum was 0.050 4～1.008 0 ?g, r =0.999 99, and the average recovery was 101.61% (RSD=1.75%, n =5). Conclusion The method is convenient and accurate, and can used be as basis of quality control for Kuding Cha of Ligustrum.

Objective To establish the method to determine the content of ?-sitosterol in Rhizoma Heterosmilacis Japonicae.Method ?-sitosterol in Rhizoma Heterosmilacis Japonicae was determined by HPLC.Chromatographic column was sinachrom ODS-BP 5 ?m column(4.6 mm?250 mm).Mobile phase was methanol-0.1% H3PO4 liquor.Detection wavelength was 210 nm.Flow rate was 1.0 mL/min.Result ?-sitosterol showed a good linear curve in the range of 0.22～8.8 ?g(r=1.000 0).The average recovery was 96.5% with RSD of 1.15%.Conclusion The method was accurate and reproducible,and can be used to control the quality of Rhizoma Heterosmilacis Japonicae.

Objective To observe the effect of Zhi Qing Capsule on the plaque formation of hyperlipemia rabbits and to discuss its mechanism.Methods Forty-eight New-Zealand rabbits were randomly divided into normal control group,hyperlipemia group,Xuezhikang control group and three Zhi Qing capsule groups.Before and after 2-week treatment,the serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C) and high density lipoprotein cholesterol(HDL-C) in the serum were determined.After 4-week treatment,TC and TG contents in the liver,and nitric oxide(NO),thromboxan B2(TXB2) and endothelin-1(ET-1) levels in the serum were measured.At the end of the sixth week,all rabbits were killed to observe aorta pathological changes.Results Zhi Qing Capsule can obviously counteract the increase of serum TC,LDL-C and liver TC in the hyperlipemia rabbits,restrain the formation of aorta atherosclerotic plaques,increase the level of NO and decrease the levels of TXB2 and ET-1.Conclusion Zhi Qing Capsule has an evident effect on resisting the lipid metabolism disturbance and atherosclerosis.

Three compounds were isolated from the leaves of Rabdosia amethystoides (Benth) C.Y.Wu et Hsuan. They were identified as Irabdosinaiol (Ⅰ), oleauolic acid (Ⅱ), ?-sitostcrol (Ⅲ) on the basis of chcmical reactions and spectral data. compounds Ⅰ and Ⅱ were isolated for the first time from this plant.

Objective To make a systematical review of the safety and efifcacy of Etomidate plus Fentanyl-class drugs and Propofol plus Fentanyl-class drugs in older patients undergoing gastroscopy. Methods We searched the Cochrane library, PubMed, Embase, China Biology Medicine (CBM), CNKI, VIP, Wanfang Database for all randomized controlled trials (RCTs) about the efifcacy of Etomidate plus Fentanyl-class drugs(Fentanyl, Sufentanil, remifentanil) in older patients undergoing gastroscopy. The quality of the studies was evaluated by the method recommended by the Jadad scale. Meta-analysis was conducted using the Cochrane Collaboration’s RevMan 5.3 software. Results 11 RCTs involving 1 535 patients were analyzed. Meta-analysis showed that patients in the Etomidate group had a lower heart rate [Weighted Mean Difference (WMD)=2.25, 95%CI(0.93, 3.56), P=0.001] and mean arterial pressure [WMD=9.09, 95%CI (7.60, 10.57), P=0.000] lfuctuation than whose of the Propofol group.The hypoxemia occurrence [O^R=0.46, 95%CI (0.32, 0.65), P=0.000] in Etomidate group is also lower than which of the Propofol group. For side effects aspects, the risk of apnea[O^R=0.26, 95%CI(0.15, 0.48), P=0.000] and injection pain [O^R=0.02, 95%CI (0.01, 0.05), P=0.000] in the Etomidate group is much lower than the Propofol group ,while the myoclonus [O^R=8.14, 95%CI (4.18, 15.87), P=0.000], nausea and vomiting [O^R=3.44, 95%CI (2.03, 5.84), P=0.000] were more incidental than the Propofol group. Conclusion Etomidate plus Fentanyl-class drugs can effectively maintain circulatory system for the old undergoing painless gastroscopy, demonstrated to be a safe and valid anesthesia method.
