Objective To explore the incidence and risk factors of bacterial infection after othtotopic liver transplantation (OLT). Methods Altogether 56 OLT recipients from January 2005 to October 2007 were included in the study. The incidents and the related variables of the infection were analyzed retrospectively. The related variables were evaluated using multivariate logistic regression model to identify the significant risk factors. Results Bacterial infection was confirmed in 29 recipients (51.8%). Among them, the lung infection was the most common site (53.7%). The Gram-positive cocci were 46.3%, while the Gram-negative bacilli were 53.7%. The risk factors for bacterial infection included duration of the operation and detained respirator using. Conclusion Bacterial infection is a major complication following OLT. Surveillance for the risk factors, enhancement the skill of operation, and improving the recovery of respiratory function is the key to decreasing the incidence of bacterial infection after transplantation.

Objective:To investigate the factors affecting the intrahepatic infection after percutaneous radiofrequency ablation(PRFA)for liver cancers.Methods:The clinical data of 1567 patients with intrahepatic infection after PRFA for liver cancers(from Dec.1999 to Oct.2007)were retrospectively summarized.Logistic regression method was used to analyze the possible affecting factors.Results:Twenty-eight person-times of intrahepatic infection occurred in 1635 patients who received a total of 2035 times of PRFA.with the infecting rate being 1.38%.The intrahepatic infection-related mortality was 0.13% (2/1567).Univariate analysis indicated that the intrahepatic infection was significantly correlated with metastatic liver cancer, pattern of past abdominal operation,tumor location,tumor size and tumor numbers(P

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.

OBJECTIVETo provide a theoretical basis for designing of lumbar intervertebral disc prosthesis by collecting the data of the lumbar endplate morphology.

METHODSA total of 100 healthy adults were measured about the following parameters: lumbar lordosis, the Cobb angle of each segment, the concavity depth (ECD) of the endplate, the location of concavity apex (ECA) of the endplate. And a correlation analysis on lumbar lordosis and ECD, ECA was made, respectively.

RESULTSIn total, 100 volunteers were measured. The mean age of the volunteer was 40 years (range 20 - 50 years); the average depth of ECD was (2. 37 ± 1. 42) mm, the average location of ECA was (52. 21 ± 9. 70) %; the average depth of ECD of inferior endplate (IEP) was (2. 81 ± 1. 52) mm (0. 54 - 7. 60 mm), and the parameter of the superior endplate (SEP) was (1. 94 ± 1. 16)mm(0. 39 - 6. 10 mm). The average depth of ECD of the IEP was bigger than of the SEP for each lumbar vertebral body. Most of the location of ECA was at the back of the intervertebral body, the average location of ECA of IEP was (49. 60 ± 8. 78) % (22. 57% - 75. 58%), and the parameter of the SEP was (55. 03 ± 9. 90) % (16. 03% -75. 58%); the mean angle of lumbar lordosis was 39. 760 11. 25°(13. 8° - 72. 00°). There was no obvious correlation between the lumbar lordosis and the ECD (r -0. 193, P =0. 195), neither was the location of ECA(r =0. 080, P =0. 592).

CONCLUSIONMost of the location of ECA is at the back of the intervertebral body, the average depth of ECD is 2. 37 mm, the average location of ECA is 52. 21%.
