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.

BACKGROUND:Psychological factors could influence the degree of pain after total knee arthroplasty. However, the effects of perioperative psychological intervention on postoperative pain and joint function are rarely reported. OBJECTIVE:To study the efficacy and safety of alprazolam for patients with anxiety and depression before total knee arthroplasty. METHODS:Sixty-one patients with anxiety and depression before unilateral total knee arthroplasty were recruited. The patients were given the treatment of alprazolam (experimental group) or placebo (control group) at 2 weeks preoperatively. Baseline data were collected, preoperative anxiety and depression were assessed with Hamilton Anxiety Scale and Beck Depression Inventory, perioperative pain at rest and in activity at each time point was evaluated, postoperative NSAIDs drugs and intravenous self-control analgesia pump usage were recorded, the peripheral neurotransmitters were detected by ELISA, short-and mediate-term joint fuction was evaluated through Western Ontario and McMaster Universities Osteoarthritis Index and Knee Society Score after joint replacement, patient satisfaction and in-hospital relevant indexes and adverse reactions were detected. RESULTS AND CONCLUSION:(1) After the application of alprazolam, anxiety and depression were improved notablely, and the levels of 5-hydroxytryptamine andγ-aminobutyric acid in peripheral blood were increased at 2 weeks. (2) The visual analogue scale scores at rest in the experiemntal group were significnatly lower than those in the control group at 12 hours, 1, 2, 3, 5 and 7 days postoperatively (P<0.05);the visual analogue scale scores in activity in the experiemntal group were significnatly lower than those in the control group at 12 hours, 1, 2, 3, and 5 days postoperatively (P<0.05). (3) Analgesia pump and analgesic drug usage in the experiemntal group were significantly less than those in the control group, and the analgesic drug dosage and preoperative anxiety depression were correlated. (4) There were no significant differences in the Western Ontario and McMaster Universities Osteoarthritis Index and Knee Society Score between two groups. (5) The patient satisfaction, sleep index and hospitation time in the experimental group were superior to those in the control group. No obvious adverse reactions occurred during medication. (6) Our results suggest that for patients diagnosised with anxiety and depression before total knee replacement, the preoperative application of alprazolam can alleviate anxiety and depression, improve perioperative pain at rest and in activity, reduce postoperative analgesia drug useage, and increase patient satisfaction.

Objective To explore the effects of obstructive sleep apnea/hypopnea syndrome (OSAHS) on the cognitive function of pilots. Methods The cognitive function of 13 pilots diagnosed as severe OSAHS and 10 healthy pilots as control was evaluated using Epworth Sleepiness Scale (ESS), Flicker Fusion Frequency Indicator, Many Reaction Time Tester, Space Place Memory Span Tester, Attention Instrument and Guard Tester. The correlation analyses were also performed between the ESS, AHI, MinSaO2% with the results of each cognitive test in the OSAHS group. Results Compared with the healthy control subjects, the scores of ESS in OSAHS group were significantly higher (P

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.
