Objective To assess the efficacy and safety of different dosages of oxycodone plus acetaminophen for treating acute pain after oral surgery,in order to provide a reasonable dosage of combination in clinic. Methods Randomized controlled trials ( RCTs ) on effect of combination of oxycodone plus acetaminophen on pain relief after oral operation were searched from the following data-bases:PubMed,EMbase,MEDLINE ( Ovid) ,the Cochrane Library,CNKI,and WANFANG from the date of their establishment to January 2015. The data of RCTs meeting the inclusive criteria were extracted according to Cochrane methods by two reviewers independently,and after the quality was evaluated and cross-checked,meta-analyses were conducted using RevMan 5.2 software. Results A total of 11 studies in 10 literatures involving 1 028 patients were included and were designated to 3 different dosage groups (5 mg/325 mg,10 mg/650 mg,10 mg/1 000 mg,respectively). The results of Meta-analyses showed that pain remission rate was significantly higher in the 3 different dosages of oxycodone plus acetaminophen groups than in the placebo group (RR5 mg/325 mg=3.35,95%CI [1.74,6.45],I2=38%,P=0.000 3;RR10 mg/650 mg=6.88,95%CI [4.00,11.83],I2=0%,P<0.000 01;RR10 mg/1 000 mg=4.94,95%CI [3.23,7.56],I2=81%,P=0.005). In additional,the RR of oxycodone 10 mg/acetaminophen 650 mg and placebo groups for pain remission rate was higher than that of the other 2 dosages groups,moreover,more studies were enrolled and its low heterogeneity led to high reliability. Usage rate of remedial painkillers was significally lower in oxycodone plus acetaminophen groups than in the placebo group (RR5mg/325mg=0.71,95%CI [0.60, 0.85],P<0.000 01;RR10mg/650mg=0.50,95%CI [0.41,0.61],P<0.000 01;RR10mg/1000mg=0.77,95%CI [0.66,0.90],P=0.001) ,In addition, the RRs of usage rate in oxycodone 10 mg/acetaminophen 650 mg and placebo groups were significantly lower than the other 2 dosages groups. Incidence rates of adverse effects were similar in the 3 different dosages groups and higher than that of the placebo group. However,the adverse events were generally described as mild to moderate in severity and rarely led to drug withdrawal according to all reports in the studies ( only one event ) . Conclusion The present study showed that combination of oxycodone plus acetaminophen can provide better analgesia in acute pain after oral surgery with high safety. In addition,combination of oxycodone 10 mg plus paracetamol 650 mg may be better for acute pain relief after oral surgery.

Objective To investigate the effect of medial collateral ligament (MCL) repair and coronoid process fracture fixation on stability of the Terrible Triad of the elbow. Methods CT and MRI scan images of elbow joints from one healthy 28-year-old male volunteer were used to establish three elbow models. Model A: normal model. Model B: repair of coronoid process fractures, without MCL repair. Model C: repair of MCL, without repair of ulnar coronoid processes. Longitudinal loads were applied on the three models to analyze the displacement and stress distributions of the elbow joint under different working conditions and compare the stability of the elbow joint. Results The displacement and stress distributions of the three models were similar. The maximum displacement and maximum stress of the articular surface were located at the ulna pulley notch, while the minimum displacement was located at the coronoid process and its medial side. The minimum stress was located at the lower lateral side of the coronoid process. There were no statistical differences in the maximum displacement and stress among the three models (P>0.05). Conclusions When the lateral column is stable, the effect of repairing the MCL and fixing the fracture block of ulnar coronoid process is similar.

Objective To investigate the differences in biomechanical properties of 3 internal fixation patterns(the lateral plate and screw group, the rear plate and screw group, and the front and rear lag screw group) for treating posterolateral tibial plateau fracture under different axial loads. Methods Based on CT data of the tibial plateau, the entity model of 1/2 and 1/4 posterolateral tibial plateau fracture with 3 internal fixations were established and meshed to analyze force status of the fracture models with 3 internal fixations under different axial loads. ResultsUnder the axial load of 1 kN, for the 1/2 posterolateral tibial plateau fracture model, the displacements of the fracture fragments in the lateral plate and screw group, the rear plate and screw group, and the front and rear lag screw were 552.082, 67.964, 54.085 μm, respectively, and the stresses on the fixation device were 306.745, 231.844, 73.047 MPa, respectively. For the 1/4 posterolateral tibial plateau fracture model, the displacements in the three groups above were 416.072, 302.107, 150.639 μm, respectively, and the stresses on the fixation device were 306.673, 208.467, 73.607 MPa, respectively. Both the displacements of the fracture fragments and the stresses on the fixation device increased correspondingly under the axial load of 1.5 kN, and the trend of the data was similar to that under the axial load of 1 kN. Conclusions The results from the fracture models with 3 internal fixation patterns show that the front and rear lag screw group has a superior biomechanical stability under two different axial loads, and the similar mechanical properties can be achieved in the rear plate and screw group. Therefore, the front and rear lag screws will be preferred to treat posterolateral tibial plateau fracture with less obvious displacement in clinic.

Objective To study the relationship between the imaging patterns of microvasculature change and histological diagnosis.MethodsOne hundred and thirty-seven patients with esophageal mucosa roughness,erosion,plaque,abnormal color and indentation in conventional endoscopy and thirty healthy volunteers were enrolled in this study.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL) changes by NBI .The biopsies underwent pathologic evaluation.The imaging patterns of endoscopy and histological diagnosis were compared and statistically analyzed.Results137 patients were diagnosed by narrow-band imaging system with magnifying endoscopy combined miniprobe sonography.Among these patients,27 cases were pathologically diagnosed as squamous cancer including 15 cases of early esophageal cancer,21 cases were high grade intraepithelial neoplasia,23 cases were low grade intraepithelial neoplasia,66 cases were chronic inflammation.100% esophageal carcinoma and high grade intraepithelial neoplasia were Ⅳ,Ⅲ type IPCL,56.52% low grade intraepithelial neoplasia was Ⅲ type IPCL,43.48% wasⅡtype IPCL,90.91% esophagitis wasⅡtype IPCL.100% esophageal normal mucosa wasⅠtype IPCL.The difference was significant among esophageal carcinoma,high grade intraepithelial neoplasia and esophagitis,esophageal normal mucosa (P＜0.05).ConclusionsThe imaging patterns of microvasculature change under NBI magnifying endoscopy were crucial in the diagnosis and identification of benign and malignant of esophageal disease.

Objective To investigate the effects of GW4064,one FXR agonist,on the leptin and OB-Rb during the differentiation of 3T3-L1 preadipocytes and on the OB-Rb in the HepG2 cells. Methods The mRNA relative expression of leptin , OB-Rb and the protein of leptin on the day of 0 , 2 , 4 , 6 , 8 during the differentiation of 3T3-L1 preadipocytes after interfered with GW4064 were detected by fluorescent real-time PCR and ELISA , respectively. Meanwhile , the mRNA relative expression of OB-Rb of HepG2 cells after treated with GW4064 0 h , 12 h,24 h,48 h were also examined. Results The mRNA relative expression of leptin in the 3T3-L1 preadipocytes and OB-Rb in the HepG2 cells after treated with GW4064 were significantly increased compared with the controlgroup. Also, the protein level of leptin was similar with the mRNA expression. The all differences were statistically significance (P<0.05). However, there was no significant difference on OB-Rb in 3T3-L1 preadipocytes cells (P>0.05). Conclusions GW4064 is able to upregulate the expression of leptin in the 3T3-L1 preadipocytes and OB-Rb in the HepG2 cells. Now the role of leptin in the NAFLD is still unkown, however, the low expression of OB-Rb is related with the leptin resistance in the pathogenesis of NAFLD. So we hypothesize that FXR agonist may treat NAFLD through upreglating the expression of OB-Rb and improving leptin resistance.

BACKGROUND: A large amount of cell dies of apoptosis in secondary injury stage after spinal cord injury.OBJECTIVE: To probe into the influence of local intraspinal infusion with danshen injection on necrosis and apoptosis of spinal cell after acute spinal cord injury.DESIGN: Randomized controlled experiment was designed.SETTING: Clinical Medical Trial Center of People' s Hospital Affiliated to Yunyang Medical College.MATERIALS: Forty-four Chinese white rabbits of first grade were employed, aged varied from 4 to 5 months, of either sex, mass weighted varied from 2.0 to 2.5 kg.INTERVENTIONS: The experiment was performed in Clinical Medical Trial Center of People' s Hospital Affiliated to Yunyang Medical College from June 2002 to July 2003. Two groups were randomized, named danshen group and the control group, 22 rabbits for each. In both groups, modified Allen method was used to prepare the model of incomplete spinal cord injury. In danshen group, danshen injection was infused from subdural catheter for 4times at 0. 3 mL/kg per day of the total amount (once every 6 hours). In the control group, physiological saline of same dose was injected. The animals were sacrificed at the 8th, 24th and 72nd hours successively after injection for pathological and histomorphologic observation, peroxide dismutase and malondialdehyde determination and determination of positive cell count of B-cell lymphoma-2 (Bcl-2), the apoptosis-inhibition gene.MAIN OUTCOME MEASURES: Cell apoptotic index and cell apoptotic rate in the region of spinal cord injury.RESULTS: Forty-four rabbits entered result analysis for all. ① Results of cell apoptosis: Apoptotic index in danshen group was less remarkably than that in the control group(13.10 ± 1. 38, 20.39±2.96, 4.101, P ＜0.01); cell apoptotic rate was lower remarkably than the control group[ (9.67 ± 1.09)%,(14.68±2.81)%, t=4.072, P ＜0.01] and Bcl-2 expression was more than that in the control group[ (19. 12 ± 4.74) /mm2, ( 13.37 ± 3.68) /mm2,t = 2. 347, P ＜ 0.01 ]. ② POD content: The result in danshen group was higher thanthe control group[ (136.20 ± 13.64) NU/mL, (101.70 ± 15.24) NU/mL,t = 4. 132, P ＜ 0.01 ]. ③ Malondialdehyde content: The result in danshen group was lower than the control group[ (1.27 ± 0. 22) nmol/mL,(2.54±0.69) nmol/mL, t=4.309, P ＜0.01] . ④Degeneration and necrosis of neuron and neural fiber: The result in danshen group was milder than the control group.CONCLUSION: After local infusion with danshen(Radix Salviae Miltiorrhizae), cell apoptosis was decreased in local spinal cord injury and cell necrosis was inhibited and alleviated after acute spinal cord injury.

Objective To explore the risk signals of adverse events （ADE） in the use of exenatide microspheres by the FDA adverse event reporting system （FAERS）, and provide reference for clinical rational drug use and drug safety. Methods With exenatide microspheres as the target drug, the search keywords were Exenatide Microspheres for Injection, LY05006 , AC 2993 LAR and Bydureon. SAS software was used to extract the ADE report data from January 2, 2012 to March 31, 2023 in the FAERS database and the duplicates were removed. Data mining of exenatide microspheres-related ADE reports was performed by the reporting odds ratio method and the comprehensive standard method. Results A total of 27 248 exenatide microspheres-related ADE reports were retrieved, involving 27 SOCs, of which 4 719 were severe ADE reports. The reporting personnel were mainly consumers （18 435 cases，67.66%）, the United States was the mainly reporting country （26 295 cases，96.50%）. A total of 163 ADE risk signals were obtained by reporting odds ratio method and comprehensive standard method, including new adverse reactions such as abnormal blood cholesterol, elevated lipase and mixed hyperlipidemia. Conclusion Based on the FAERS database, the post-marketing ADE of exenatide microspheres was mined and analyzed, which could provide reference for clinical medication safety and improvement of patients' medication compliance.

OBJECTIVETo study the emergency care effect of in-hospital severe trauma patients with the injury severity score (ISS) larger than or equal to 16 after medical staff received advanced trauma life support (ATLS) training.

METHODSATLS training was implemented by lectures, scenarios, field practices, and examinations. The clinical effect of in-hospital severe trauma care was compared 2 years before and after ATLS training.

RESULTSDuring 2 years (from January 1, 2004, to December 31, 2005) before ATLS training, 438 cases of severe trauma were admitted and treated emergently in our department. Among them, ISS score was 28.6+/-7.8 on average, and 87 cases died with the mortality of 19.9%. The duration in emergency department and from admission to operation were 69.5 min+/-11.5 min and 89.6 min+/-9.3 min respectively. Two years (from January 1, 2007, to December 31, 2008) after ATLS training, 382 cases of severe trauma were admitted and treated. The ISS was 25.3+/-6.1 on average and 62 cases died with the mortality of 15.1%. The duration in emergency department and from admission to operation were 47.8 min+/-10.7 min and 61.5 min+/-9.9 min respectively. The ISS score showed no significant difference between the two groups (P > 0.05), but the mortality, the duration in emergency department and from admission to operation were markedly decreased after ATLS training and showed significant difference between the two groups (P <0.05).

CONCLUSIONATLS course training can improve the emergency care effect of in-hospital severe trauma patients, and should be put into practice as soon as possible in China.
