Objective To investigate the causes and measurement of the colonic fistulas after severe acute pancreatitis(SAP),so as to increase its cure rate.Method A retrospective study was made on 19 SAP cases complicated with colonic fistulas after drainage operation in order to find out the risk factors,the location and the time of complicated colonic fistulas,and to sum up the experiences of earlier diagnosis and comprehensive treatment.Results Most patients occurred colonic fistulas within 4~6 weeks postoperation.Seventeen patients recovered,the cure rate being 89.5%(17/19),and two case died of serious systemtic infection and multiple organ systemtic failure.Conclusions Colonic fistulas complicated by SAP is related to anatomic factors,the degree of local inflammation,the way of draingic tube putted away,and improper surgical therapy.Comprehensive therapy including taking double cannula to drainage in active,earlier jejunostomy nutrition support or colostomy,supplementing with recombinant human growth hormone can lead to better results.

Objective To study the therapeutic effect and mechanism of enteral nutrition support for treatment of chronic cardiac failure of rats.Methods Ligature of abdominal aorta was used to prepare SD rat model of chronic cardiac failure.The rat models of cardiac failure were randomly (random number) divided into three groups:conventional therapy group,conventional therapy plus enteral nutrition support group and non-therapy group.The rats in conventional therapy group were administrated with routinely used drugs for chronic cardiac failure.The rats in conventional therapy plus enteral nutrition support group were treated with conventionally used medicine plus enteral nutrition liquid.The rats in non-therapy group were given the same amounts of dummy medicine and normal saline.Ultrasonic cardiography,ELISA for detection of atrial natriuretic peptide (BNP) and examination of pathological change in myocardium tissues after HE staining were carried out for comparison of cardiac function of rats with chronic heart failure between pre-and post-treatment.Results The commonly used drug enabled the heart of rats with chronic heart failure to elevate the LVFS (left ventricular fraction shortening) and LVEF (left ventricular ejection fraction) levels (q=3.59,P＜0.05; q=4.01,P＜0.05),to decrease the BNP in blood plasma (u=2.285,P＜0.05) and to lessen the injury of myocardial tissue (u =2.332,P ＜ 0.05).However,compare to the chronic cardiac failure rats administrated with commonly used drug,the chronic cardiac failure rats treated by combination of the commonly used drug and enteral nutrition liquid presented significantly higher LVFS and LVEF levels (q =4.34,P ＜ 0.05 ; q =3.98,P ＜ 0.05),lower plasma BNP level (u =2.548,P ＜0.02) and milder injury of myocardial tissue (u=2.631,P＜0.02).Conclusions The commonly used drug plus enteral nutrition support promotes in higher efficiency the heart function of chronic cardiac failure rats,suggesting that this nutrition support can be used as an adjuvant therapy for patients with chronic cardiac failure in clinic.

Objective To explore the risk and prognosis factor of cranial nerve injury in non acquired immune deficiency syndrome(AIDS)-related cryptococcal meningitis.Methods The clinical data of 115 patients with non-AIDS-related cryptococcal meningitis were reviewed retrospectively.Clinical characteristics,initial antifungal therapies and outcome of these patients were analyzed.The risk and prognosis factor was performed by multivariate Logistic regression.Results The incidence of cranial nerve injury was 35.7％(41/115).Among of them,the involved ratio was 48.8％ (20/41),39.0％ (16/41),24.4％ (10/41),12.2％ (5/41),7.3％ (3/41),4.9％ (2/41) in optic nerve,oculomotor nerve,acoustic nerve,abducent nerve,olfactory nerve,facial nerve.Predictive risk factor for cranial nerve injury was duration of diagnosis (OR =1.057,95％ CI 1.003-1.112),low cerebrospinal fluid cell count and intracranial hypertension were also the independent predictive factors (both P ＜ 0.05).In the follow-up peried,72.2％ (26/36) patients who had cranial nerve injury were fully recovered,with a median time of 0.5-24.0 (3.8 ±1.7) months.The independent predictors of recovery were numbers of nerve involved (OR =0.241,95 ％ CI 0.067-0.801,P =0.023) and combination therapy (OR =10.328,95 ％ CI 2.087-51.026,P =0.006).Condusions Cranial nerve injury is common in non-AIDS-related cryptococcal meningitis.Delay in diagnosis,intracranial hypertension and low cerebrospinal fluid cell count are independent predictive factors.Less cranial nerve involvement and combination therapy predicts recovery.

The evaluation on clinical efficacy of traditional Tibetan medicine (TTM) is an important scientific subject during the development of TTM. Firstly, the authors introduced the current situations and problems in evaluation on clinical efficacy of traditional Tibetan medicine both at home and abroad in this study. Secondly, they compared the similarities and differences between TTM and traditional Chinese medicine (TCM) in evaluation on clinical efficacy, define their differences in details but not in nature, and proposed that TTM could selectively learn TCM's experiences in clinical research and build a specific methodology system for evaluation on clinical efficacy according to its own characteristics. Thirdly, they discussed the methodological challenges in evaluation on clinical efficacy of TTM, including the pending clinical research guidelines and disease diagnosis standards according to its own characteristics. Finally, they propound some suggestions for promoting the evaluation on clinical efficacy of TTM, including the comprehensive application of multiple research methods, overall research-based evaluation on efficacy of TTM complex intervention and selection of accepted and objective outcome indexes for efficacy evaluation.
