Nine cases of hepatic abscess were diagnosed by Seldingers technigue. The angiographic features consisted of 1)no hepatic artery dilatation:2)vasculas encase- ment sign:3)cavitery ring sign 4)relative low density cavity sign.Five patients with ab- scess diameter over 4era,but one,performed partial hepatic resection ended other totally four underwent percutaneous transhepatic abscess intervertional therapy,including venous puncture drainage of pus;washing vomiea;periodic retained cathertee for antibiotic and an- tiamebic therapy.All four patients were off hospital one and two weeks later:The effect of interventinal therapy is better than that of medical therapy and surgery.

OBJECTIVETo explore the value of the application of oil red O staining in spinal cord injury (SCI) of rats.

METHODSWith simple randomization, 24 Spargue-Dawley male rats were divided into normal control group including 6, and SCI group including 18. Spinal cord was transected at spinal lever T10 to build SCI model. Six rats of SCI group were sacrificed randomly at 1, 2, 4 weeks after surgery. After the spinal cord tissue sections were made, oil red O staining methods were used to observe the changes at the end of transected spinal cord. Images were analyzed by Image-Pro Plus 6.0 and SPSS 20.0 software.

RESULTSThe oil red O staining of normal control group showed that white matter surrounded by myelin sheath was clear and obviously distinctive from grey matter. Uneven and strengthened staining in oil O was observed in grey matter of SCI group at 1, 2, 4 weeks post-SCI.

CONCLUSIONIt is a good method to label the myelin sheath in spinal cord and distinct white matter from grey matter by oil red O staining. Analysis of the images showed that lipid may become another target for drugs, which needs more researches.

Objective To systematically review the efficacy and safety of erythromycin on enteral nutrition (EN) tolerance in adult critical care patients.Methods Databases including PubMed,EMbase,the Cochrane Library,CNKI and Wangfang data were retrieved up to June,2013 to collect the randomized controlled trial (RCT) concerning erythromycin in improving EN tolerance or increasing the successful rate of postpyloric EN tube as compared with other treatments.Two reviewers independently screened the literature,extracted the data,and assessed the quality of methodology.Then Meta-analysis was performed using RevMan 5.2 software.Results A total of 16 RCTs were included.Ten RCTs involving 668 patients were included for evaluating erythromycin in improving EN tolerance.Six RCTs involving 353 patients were included for evaluating erythromycin to increase the successful rate of postpyloric EN tube.The result of Meta-analysis showed that compared with placebo,erythromycin could significantly improve the successful rate of postpyloric EN tube placement [relative risk (RR) =1.82,95％ confidence interval (95％CI) 1.40-2.37,P＜0.000 01],while there was no significant difference between erythromycin and metoclopramide (RR=1.04,95％ CI 0.79-1.36,P=0.799).In patients who needed early EN,compared with placebo or blank control,erythromycin had higher successful gastric feeding rate over 5 days (RR =1.89,95％ CI 1.19-3.00,P=0.007).In patients who failed EN,compared with metoclopramide,erythromycin could significantly increase the successful gastric EN rate for 24 hours (RR=1.30,95％CI 1.02-1.66,P=0.03),72 hours (RR=1.57,95％CI 1.15-2.14,P=0.005) and 144 hours (RR=2.04,95％CI 1.23-3.37,P=0.006).The median time of EN intolerance was postponed in erythromycin group than that in metoclopramide group.Adverse reactions were reported in 5 studies.There was no statistic difference except for the higher diarrhea rate in the combination treatment group compared with erythromycin group.Conclnsions Postpyloric EN tube placement rate can be improved by erythromycin,which could be a choice of substitute for bedside intubation without fluoroscopy or endoscopic assistance.Based on the evidence,we recommended that intravenous erythromycin in a small dose of approximately 3 mg/kg weight as an option for EN intolerance in critical patients.

This study aimed at investigating the effects of Guttiferone K (GUTK),a polycyclic polyprenylated acylphloroglucinols (PPAPs) compound isolated from Garcinia yunnanensis,on the cell proliferation of human prostate cancer LNCaP cell line.Human prostate cancer LNCaP cells in the period of logarithmic phase were treated with GUTK.MTI assay was used to detect cell proliferation.Flow cytometry of propidium iodide (PI) staining,BrdU assay and immunocytochemistry were adopted to analyze the cell cycle phase distribution.Protein levels of Cyclin A,p27 and SKP2 were detected by western blotting.The results showed that GUTK inhibited the proliferation and induced G0/1 arrest of LNCaP cells in a time and dose dependent manner.The protein levels of Cyclin A and SKP2 were decreased,while p27 was increased by GUTK in human prostate cancer LNCaP cells.It was concluded that GUTK,a compound isolated from G.yunnanensis,presented the effect of inhibiting the cell proliferation by inducing G0/1 arrest of human prostate cancer LNCaP cells,with potential anti-prostate cancer action.

Objective To investigate the emotional memory characteristic in patients with leuloaraiosis(LA) and explore the neurobiological mechanisms through observing the changes of emotional memory.Methods Different valence images (including positive,neutral and negative pictures) were used to test twenty-four patients with Leuloaraiosis(LA group)and twenty-four healthy colltrols(HC group) at the same time.The emotional memory was evaluated by the recognition of emotional pictures.Results In appraisal of the emotional pictures,there was no significant difference between patients with LA (positive (10.42±2.30) and neulral (12.87±2.29),respectively) and healthy controls (positive (11.38 ± 3.25) and neutral (12.75 ± 2.86),respectively) in positive and negative appraisal (all P＞0.05).But the negative appraisal decreased between LA group (11.63 ± 1.81) and HC group (12.75 ± 2.02) (P＞ 0.05).Compared with healthy controls (38.08+±5.45),patients with LA(33.67±7.10) showed sharply decline in the emotional images memorizing task(P＜0.05).And the accuracy in recognizing positive and netural valence pictures in patients with LA ((Positive(11.04±2.40) and neulral (10.42±2.93)) was significantly lower than that in healthy controls ((positive(12.79±2.17) and neutral(12.08±2.59))(P＜0.05).But in negative stimulus,there was no significant difference between LA group(13.20± 1.86)and HC group(12.20±2.65) (P＞0.05).In addition the total correct recognition,positive and neutral valence in pictures recognition were negativly correlated with the se verity of white matter lesions in the LA patients group(r=-0.308,P=0.033;r=-0.462,P=0.003;r=-0.352,P=0.014).Conclusion The emotional memory is impaired in patients with LA,and the degree of damage is accompornied with the severity degree of LA.The emotional memory for positive and neutral vanlence pictures is impaired but the emotional memory for neutral is relatively reserved in patients with LA in pictures recognition phase.It suggests that impaired emotional memory with different valences may be related to different neuromechanisms.

ObjectiveTo investigate the dynamic expression of Mindin protein in mice with acute liver injury induced by carbon tetrachloride (CCl4) and its mechanism of action. MethodsA total of 48 male C57B1/6 mice were selected and divided into experimental group (n=40) and control group (n=8). The mice in the experimental group were given intraperitoneal injection of CCl4 olive oil to induce acute liver injury, and the liver tissue was collected for pathological observation at 6, 12, 24, 48, and 72 hours after modeling. The mice in the control group were given intraperitoneal injection of olive oil. Western blot was used to measure the protein expression of Mindin and its change trend, and quantitative real-time PCR was used to measure the mRNA expression of Mindin. The t-test was used for comparison of continuous data between two groups. ResultsAbnormal liver structure was observed after liver injury was induced by CCl4, with the most significant pathological change at 48 hours. There was a low protein expression level of Mindin within 12-72 hours after the injection of CCl4. The mRNA expression of Mindin reached the lowest level at 12 hours after CCl4 injection and there was a significant difference between the experimental group and the control group at this time point (0.183±0.105 vs 1.023±0.247, t=8.841, P＜0.01); then there was a gradual increase in the mRNA expression of Mindin, and at 48 and 72 hours, the mRNA expression of Mindin in the experimental group was more than 2 times that in the control group (48 hours: 2.548±0.775 vs 1.023±0.247, t=5.428, P＜0.01; 72 hours: 2.699±0995 vs 1.023±0.247, t=4.621, P＜0.01). ConclusionThere is a significant change in Mindin protein during the process of acute liver injury induced by CCl4 in mice, which is characterized by the downregulation of protein expression and the regulation of post-transcriptional mRNA level, suggesting that Mindin may play an important role in the process of acute liver injury induced by CCl4.

BACKGROUND:Fast track surgery, also cal ed enhanced recovery after surgery, is a series of optimal measures adopted during the perioperative period on the basis of evidence-based medicine, to reduce the physical and mental trauma brought to the patient and accelerate their recovery. It has become the research focus of orthopedic clinic as the surgery and anesthesia skil s are improved a lot in recent years, especial y the articular surgery, which has been widely used in clinics. OBJECTIVE:To summarize the clinical study of the application of optimal measures in joint replacement surgery both at home and abroad in recent years. METHODS:The first author searched related articles in PubMed and Chinese Journal Ful-text Database from January 1997 to September 2016. The key words were“joint replacement, enhanced recovery after surgery, multi-mode analgesia, diet management, steroid hormones”. 81 articles were found at last and one monograph was included. RESULTS AND CONCLUSION:(1) We found that the recovery plan reduced the hospital stays of the patients from 4-12 days to 1-3 days, including pre-operative health education, shortening fasting and water-depriving duration before surgery, super-anesthesia before surgery and do not place catheter;adopting general anesthesia and appropriate adductor canal to relieve the pain, and stopping bleeding using tranexamic acid during operation;multi-mode analgesia, faster function exercise after anesthesia recovery, and drinking water in early phase after surgery during the perioperative period of joint replacement surgery conducted by the cooperation of surgeon, anesthetist, nurse and nutritionist. There were no significant improvements of postoperative complications rate and rehospitalization rate. (2) The research found that, enhanced recovery after surgery is suitable for most of the patients receiving joint replacement surgery, including those in advanced age, combined heart and lung disease before surgery, type 2 diabetes and smoking and drinking before surgery.
