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.

Panax notoginseng (PN) is one of the commonly used clinical medicines for cardiovascular diseases and possesses a variety of pharmacological effects. P. notoginseng saponins (PNS) are the most important bioactive components in PN. The purpose of this study was to explain the mechanism of PNS on molecular network level. 18 targets of the main medicinal ingredients of PNS were gained by virtual screening based on pharmacophores and data mining. A protein interaction network of PNS was constructed with 189 nodes and 721 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 14 modules were detected. Gene ontology (GO) enrichment analysis of the modules demonstrated that the roles of PNS played in cardiovascular disease related to multiple biological processes, which could represent the characteristics of traditional Chinese medicine (TCM) as a whole to regulate the disease. The results showed that the blood circulation and hemostasis efficacy of PN related with the biological processes such as positive regulation of cAMP metabolic and biosynthetic process, platelet activation and regulation of blood vessel size, regulation of T cell proliferation and differentiation and so on. Therefore, the module-based network analysis will be an effective method for better understanding TCM.

BACKGROUND: The perioperative hemorrhage of knee surgeries is a difficulty in clinic, and the efficacy of tranexamic acid to reduce postoperative bleeding has attracted more attention, but choosing which administrations remains controversial. OBJECTIVE: To investigate the efficacy of tranexamic acid by intravenous injection or articular injection for reducing the perioperative hemorrhage of total knee arthroplasty. METHODS: Sixty patients undergoing unilateral total knee replacement were enrolled, and were then randomized into three groups (n=20 per group): no tranexamic acid administration (group A); intravenous dropping of 15 mg/kg tranexamic acid before tourniquet application plus 10 mg/kg tranexamic acid at 3 hours postoperatively (group B); articular injection of 50 mL saline diluted with 1 g tranexamic acid through a drainage tube (group C). Two-hour closure of drainage tube was performed in all patients. The postoperative dominant and hidden blood loss, blood transfusion rate, pulmonary embolism as well as lower extremity deep venous thrombosis were recorded. RESULTS AND CONCLUSION: (1) The dominant and hidden blood loss in the groups B and C were significantly less than those in the group A (P < 0.05); the dominant blood loss showed no significant difference between groups B and C (P > 0.05); the group B exhibited a significantly less hidden blood loss compared with group C (P < 0.05). (2) The blood transfusion rate in the groups B and C was significantly lower than that in the group A (P < 0.05). (3) No pulmonary embolism or lower extremity deep venous embolism occurred during 3-month follow-up. (4) That is to say, tranexamic acid can obviously reduce perioperative blood loss and blood transfusion rate without pulmonary embolism or lower extremity deep venous thrombosis, and intravenous administration exerts better clinical effectiveness.

OBJECTIVETo evaluate the efficacy of hepatitis B viruse (HBV) vaccination and its influencing factors among children in rural area of Jiangsu province.
METHODSTwenty-five hundred and twenty-two children born after 1998 in rural area were selected as the study population using multistage cluster sampling method. HBsAg and anti-HBs were detected by enzyme linked immunoassay (ELISA) and radio-immunoassay (RIA), respectively. Anti-HBs negative children were boosted using different hepatitis B vaccines and the efficacy was compared. Factors causing HBV infection in HBsAg positive children were also investigated.
RESULTSHBsAg positive rates in 1-7 year olds were 0.28%-1.28%, and the anti-HBs positive rates decreased from 76.7% to 45.5%. The HBsAg positive rate in children not timely vaccinated was significantly higher than those with HBV vaccine injection within 24 hours after birth (1.4% vs. 0.5%, P = 0.031). More than 90% of the anti-HBs negative children had protective level of anti-HBs after boosted with HBV vaccine.
CONCLUSIONHBsAg positive rate in children born after 1998 in rural area of Jiangsu province decreased significantly, with an average of 0.8%. The reason for HBsAg carriage in children might be attributed to mother-to-infant transmission or not timely HBV vaccination.

OBJECTIVETo explore a new technique of reduction and internal fixation for tibia intercondylar eminence fractures under arthroscopy.
METHODSFrom June 2004 to February 2006, 9 patients with fresh tibia intercondylar eminence fracture (type II in 4 cases and type III in 5 cases) were treated with reduction and internal fixation using suture anchors (Depuy Mitek) under arthroscopy. All the patients, subject to regular post-operation functional exercise, were followed up for 6 to 22 months. The results were evaluated in the aspects of fracture reduction healing, knee joint relaxation and ROM, and functional restoration of overall limbs.
RESULTSIn the nine patients, the tibia intercondylar eminence fractures healed without displacement and nonunion. No knee joint relaxation or extension-restriction was found. Lysholm score indicated 93.8 +/- 2.3 at the 6th postoperative months.
CONCLUSIONThe reduction and internal fixation of tibia intercondylar eminence fractures under arthroscopy using suture anchors demonstrate a reliable and easy-to-use technique. Operation under arthroscopy helps diagnose and treat other complications inside knee joint, merely resulting in slight injury. In addition,early functional exercise contributes to rapid recovery of knee joint's functions.

OBJECTIVE:
Using the CT three-dimensional reconstruction to measure the activity degree of atlanto-occipital joint and the atlantoaxial joint in different directions and its coupling movement in healthy volunteers, and three dimensional motion range of the maximum rotation position of the upper cervical spine of cervical spondylosis patients, and to analyze the differences, verifing the reliability of the method at the meantime.
METHODS:
From January 2014 to June 2015, 20 healthy adult subjects(healthy adult group), and 26 patients with cervieal spondylosis(cervical spondylosis group) were selected. In healthy adult group, there were 11 males and 9 females, aged from 22 to 26 years old with an average of (24.0±1.2) years, and in cervical spondylosis group, there were 24 males and 2 females, aged from 36 to 72 years old with an average of (52.8±8.6) years. Healthy adults underwent CT examination in neutral position, maximum right rotation, maximum right lateral bending, maximum flexion and extention, and cervical spondylosis patients underwent CT examination in neutral position, maximum right rotation. Then the software Mimics was used to reconstruct occiput (Oc), atlas(C1) and axial(C2) vertebral three-dimensional image. Three virtual non-collinear markers were positioned on prominent structures of foramen magnum, C1 and C2. The 3D spatial coordinates of these virtual anatomical markers entail the definition of an anatomical local coordinate system which represent the position and orientation of the bones. Segmental motions were calculated using Eulerian angle in three major planes, and the difference between cervical spondylosis group and healthy adult group were compared. Due to the inaccuracy in anatomical landmark idenrification, two groups were measured 3 times, and the reliability of the experimental metnod was verified by the intra-group correlation (intra-group ICC) and the inter-group correlation coefficient(inter-group ICC).
RESULTS:
Reliability verification results:the intra-group ICC and inter-group ICC results were all above 0.90, and the measurement method had high reliability. Three-dimensional activity of the upper cervical spine in healthy adults:the atlanto-occipital joint had(-6.8±1.5)° coupled left lateral bending and (8.9±2.0)° coupled extension in the maximum right rotation position, and the motion of atlanto-occipital joint had low activity[maximum was(5.3±2.6)°] in the remaining 3 positions; the rotation of atlanto-axial joint was(37.9±5.1)°, accounting for 52.34% of the total cervical spine activity[(72.4±5.0)°] in the maximum right rotation position, and rotational motion was still prominent in the remaining three positions. The relative translations of the upper cervical spine in all direction were small. The average axial rotation angle [(62.0±3.4)] ° of the total cervical spine in cervical spondylosis group was significantly lower than that in the healthy adult group, but the mean axial rotation angles of the atlanto-occipital and the atlantoaxial joint were not significantly different from those of the healthy adults(>0.05).
CONCLUSIONS
The three-dimensional CT reconstruction method has high reliability, which can be applied to measure the movement of spine. The upper cervical spine contributed the most to the direction of rotation, and the movement in all directions are accompanied by coupled motion in the other direction. There was no significant difference in the rotation of the upper cervical spine between cervical spondylosis patients and normal subjects.
