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 Implementing the scientific research performance evaluation indicator system constructed to evaluate the situation of scientific research performance conducted by two basic Departments during the 12th Five-Year period in a general hospital.To understand the practical applicability of the scientific evaluation index system,and also propose comments and suggestions based on the comparison between assessment score and actual research situation in the departments.Methods Based on the database of scientific research management information platform,collect related research data from two basic departments of the hospital in latest five years.Using SPSS software to conduct statistical analysis on the total score of the first and two indicators,as well as the specific indicators of the three indicators,according to the performance evaluation index system and the weight built by the hospital.Results The index system can basically reflect the general information of scientific research input and output in the department,however,some indicators cannot truly reflect the index importance and the differences between the index weight is not significant,so it is necessary to make amendment based on demonstration.Conclusions Hospital should dynamically update the index system to make them match the developing strategy of the hospital,also important to combine them with research stimulation to guarantee more scientific management and better service to the research development of hospitals.

Objective: To observe the changes of Bcl-xl expression in hippocampus of the rats with the forced-swimming and the changes of Bcl-xl after poststress. Methods: The protocol was established with the forced-swimming as the chronic stress model. Open-field test was executed to measure the behaviors of the rats. Immunohistochemistry was used to observe the changes of Bcl-xl expression in the hippocampus. Results: Compared to the control group,the expression of Bcl-xl in CA3 region of the hippocampus and dendate gyrus(DG)of the rats was decreased morphologically. With the computerized image analysis, the gray degree increased significantly (P

BACKGROUND: Clinical studies have discovered heart rate variability (HRV) is closely correlated with autonomic nervous system, sub-health and sudden death. Medical studies have summarized some chaotic medical science and homeostasis relevance theory. But so far the combination could still not systematically explain the clinical manifestation or summarize the diagnostic standards for sub-health and effective index to prevent sudden death. OBJECTIVE: To elucidate the correlation among autonomic nervous system, sub-health and sudden death by using chaotic medicine and homeostasis, so as to provide theoretical basis for evaluating sub-healthy state using HRV and preventing sudden death HRV. RETRIEVAL STRATEGY: A computer-based online search of Pubmed was undertaken to identify the articles published in English between January 1995 and June 2007 with the keywords of "chaotic medicine, heart rate variability (HRV), Sudden death, Sub-health, homeostasis". Meanwhile, the Weblog and CNKI database were searched for relevant articles dated from January 1995 and June 2007 with the same keywords in Chinese. Fifty-six papers were searched. After the first trial, only articles ①closely correlated with chaotic medical science, sudden death and sub-health, and ②published recently or in authority magazine in same field were selected. Repetitive studies were excluded. LITERATURE EVALUATION: The review articles, basic and clinical experiments about chaotic medical science, HRV, sudden death, sub-health, and homeostasis as well as articles published in related weblogs were selected. DATA SYNTHESIS: ①In any individual composed of multi-cells and multi-system, there are at least three-level chaotic system: overall chaotic system, cardiovascular chaotic system maintaining the blood pressure and cell chaotic system. Healthy state is that the three chaotic systems are in normal condition. Disease and sub-healthy state is the sub-stable state of chaotic system caused by the overstress of central nervous system, overexcitation of autonomic nerves and HRV decrease when there is some cell or cardiovascular system malfunction, and the information is feedback to central nervous system. ②Based on the theory about chaotic medicine and homeostasis, there are four states in individual chaotic motion: health, disease, sub-health, and homeostasis border before sudden death. The health is the homeostasis of body; disease and sub-health are the sub-homeostasis and may develop from healthy state because various factors; they may transform each other and both of them may lead to sudden death for unsteady. ③The extreme tension of central nervous system and over-excitation of autonomic nerves result in the destabilizing overall chaotic motion. Stimulation induces system destabilizing and sudden death because the patient cannot maintain arterial blood pressure. CONCLUSION: Long-term healthy state is unpredictable, but we can forecast 1-2 days situations by short-term HRV testing for 512 times in the early morning of every day, and judge the healthy state after sleep, and the change tendency of healthy state. Accordingly, we could predict person is in healthy state, sub-healthy state or unsteady border state that could cause sudden death.

Objective To systematically assess the relationship between oral administration of aspirin and survival benefit for patients with colorec?tal cancer(CRC)by meta?analysis. Methods Relevant studies were identified through searching PubMed and EMBASE. Random?effects model was derived to composite the pooled hazard ratio for overall mortality and CRC?specific mortality. The subgroup analysis was conducted for included data,and the bias analysis was reported. Results Thirteen studies on aspirin therapy were finally included in this meta?analysis. The overall surviv?al benefit associated with oral administration of aspirin represented an HR of 0.83(95%CI:0.71?0.96). Oral administration of aspirin was also asso?ciated with CRC?specific survival(HR=0.77,95%CI:0.64?0.93). No evidence was observed of an association between prediagnostic aspirin use and CRC overall survival(HR=1.00,95%CI:0.85?1.18)or CRC?specific survival(HR=0.97,95%CI:0.83?1.13). Conclusion These findings provide further indication that post?diagnostic aspirin therapy can improve CRC prognosis.

The degradation kinetics of chlorogenic acid (5-CQA), cryptochlorogenic acid (4-CQA), and neochlorogenic acid (3-CQA) in aqueous solution at 37 degrees C and different pH values (7.05, 7.96, 9.25) were investigated in the present work. The results indicated that 3-, 4- and 5-CQA tended to remain stable in acidic pH circumstance, and unstable in neutral and alkaline pH circumstance. With the increase of the alkalinity, the degradation of 3-, 4- and 5-CQA was increased leading to a less amount of total CQA and was satisfactorily described by the Weibull equation. Meanwhile, caffeic acid was not detected after the degradation of CQA. Moreover, the degradation of 3-CQA and 5-CQA tended to be converted to 4-CQA, and the degradation of 4-CQA tended to be converted to 3-CQA rather than 5-CQA. The comparison of the degradation kinetics parameters of 3-, 4- and 5-CQA at neutral and alkaline pH values showed that the orders of the rate constant (k) values were 4-CQA > 3-CQA > 5-CQA, while the orders of the degradation half life (t½) values were 4-CQA < 3-CQA < 5-CQA, indicating the orders of the stabilities of 3-, 4- and 5-CQA at 37 degrees C and neutral and alkaline pH values were 4-CQA < 3-CQA < 5-CQA.
