OBJECTIVE: Aseptic prosthetic loosening is a primary problem of total hip arthroplasty. For this reason, several prosthesis interfaces with different characteristics have been studied, such as ceramic-on-ceramic prosthesis. The purpose of this study wasto investigate the mid- and short-term curative effects of ceramic-on-ceramic total hip arthroplasty in treatment of avascularnecrosis of the femoral head (ANFH) and to evaluate its clinical application value.METHODS: A total of 23 patients (28 hips) with ANFH who received ceramic-on-ceramic non-cement hip prosthesis replacementwere followed up. All hip prostheses were BiCONTACT~((R)) ceramic-on-ceramic hip prostheses. Functional evaluation was assessedaccording to the Harris hip score. Radiographic analysis was performed using the Gruen's zonal method for the stem and the zonal classification of Delee-Charnley for the cup implants.RESULTS: All patients were followed up for an average of 28 months. The mean Harris hip scores ranged from 39.45 points prior to surgery to 88.57 points after surgery, with a difference which was significant (P < 0.05). Radiographically, no obvious prosthesis loosening or subsidence was observed. CONCLUSION: The ceramic-on-ceramic total hip arthroplasty can produce good short-term curative effects in treatment of ANFH.Radiographic findings do not show obvious prosthesis loosening.

Objective To compare the application effects of pentobarbital sodium ,urethane and midazolam combined with ket-amine/Sumianxin Ⅱ in rabbit bone defect repair .Methods 120 healthy male adult rabbits were randomly divided into three groups according to different anesthetic agents ,40 cases in each group .The group A was intramuscularly injected by pentobarbital sodium , the group B was given urethane by the ear vein and the group C was given midazolam combined with ketamine/and Sumianxin Ⅱ by intramuscular injection .The onset time of anesthesia ,maintenance time ,breathing rate ,heart rate ,complications ,recovery time ,ad-ditional anesthetic agents and postoperative death rate in 3 groups were recorded respectively .Results The onset time of anesthesia in the group B and C was(4 .53 ± 0 .65) min and(3 .56 ± 1 .31) min respectively ,which were significantly shortened compared with the group A(P<0 .05);the maintenance time of anesthesia in the group B was (152 .12 ± 12 .53) min ,which was significantly short-ened compared with the group A and C (P<0 .05);the recovery time in the group C was (31 .05 ± 5 .73) min ,which was significant-ly shortened compared with the group A and B(P<0 .05) ,the propability of additional anesthetic agents and the postoperative mor-tality in the group C were significantly decreased compared with the group A and B (P<0 .05) .Conclusion The combined anesthe-sia of midazolam and ketamine/Sumianxin Ⅱ has definite effect without any observed intraoperative depressions of breathing rate and heart rate and with high safety ,high controllability and less influence on the long term survival of the experimental animals , which is a more ideal anesthesia method of the rabbit bone defect repair .

Objective To investigate the clinical characteristics and prognosis of acute myocardial infarction (AMI) combined with ventrical septal perforation (VSP).Methods Fifty-seven AMI + VSP patients were retrospectively analyzed their clinical characteristics and outcomes who were treated in the Fourth People' s Hospital of Shenyang and the First Hospital Affiliated to China Medical University from June 2000 to May 2014.Results Of all patients,43 (75.4％) VSP occurred anterior wall AMI,and 14 (24.6％) were not.Echocardiogram show the end diastolic diameter of left ventricle was (53.7 ± 9.5) mm,left ventricle ejection fraction was (48.5 ± 11.8)％,VSP diameter was (9.8 ±7.9) mm,and 37(64.9％) were with near apex.The level of cardiactroponin I,C-reactive protein,and N terminal of B type natriuretic peptide of patients were (16.7 ± 12.9) μg/L,(99.7 ± 31.40 mg/L,(3 051.2 ± 879.7) μg/L.Total mortality was 71.9％ (41/57) in 30 days and 78.9％ (45/57) in 1 year.The mortality of operation group was 73.9％ (17/23) in 30 days and 91.3％ (21/23) in 1 year.The mortality of consecutive therapy was 64.7％ (22/34) in 30 days and 76.5％ (26/34) in 1 year.Conclusion The mortality of AMI + VSP is higher and operation is the most effective therapeutic method.

Vulnerable plaque (VP) has been widely considered as the main cause of acute coronary syndrome (ACS) and cardiac death .In recent years ,invasive or non-invasive intravascular ultrasound imaging has become one of main measures for detecting VP .The present article made following overview on advantages and disadvantages of intravascular ultrasound imaging assessing VP .

BACKGROUND: Traditionally, bee venom can treat rheumatic arthritis,rheumatoid arthritis(RA) and so on, but it has strong side effects. So it has been hoped for a long time that the effective angle component could be screened from bee venom, which can be used for the treatment of arthritis perfectly than bee venom.OBJECTIVE: To investigate whether bioactive peptide from bee venom could inhibit infection of arthritis by regulating immunological function so as to probe into a new treatment for RADESIGN: Completely randomized controlled experimental trial based on experimental animalsMETHODS: A municipal key laboratory of animal biology.MATERIALS: The experiment was carried out in the Chongqing Key Laboratory of animal biology from January 2001 to May 2002. Totally 80 rats of clean grade aged 2 to 3 months old with the body mass of 180 to 200 g were provided by Animal Experiment Center of Third Military Medical University of Chinese PLA. The experimental animal certification number was SYXK1 (army) 2002 -007. The animals were divided into 3 groups: normal control group( 10 cases), arthritis group( 10 cases), bioactive peptide group(30 cases).METHODS: Adjuvant-induced arthritis animal models were used and bioactive peptide were given to the animals by muscle injection to observe the knuckle volume and knuckle index changes.MAIN OUTCOME MEASURES: The effect of bioactive peptide from bee venom on the change of knuckle volume and knuckle index in adjuvant-induced arthritis ratsRESULTS: Ten days after injection of 0. 15 mg for each rat, the volume of the paw was (4.72 ±0. 58) mL and the knuckle index was (4.47 ±0.46) mL,which there was significant difference compared with the control group (P＜ 0. 05).CONCLUSION: P-peptide possibly has certain inhibitory effect on the development of the adjuvant-induced arthritis in Wistar rat, and will possibly be a potential therapeutic drug.

With the method of fluid-filled stomach and intravenous administration of anisodaminal hydrochloridum(654-2), 94 cases of 11 gastroduodenal diseases including gastric cancer and others were examined with ultrasound. Comparison of the ultrasonography with the pathological changes was done. The finding rate of gastric foci which equal to or more than 5mm in diameter was 96.8%. The correct rate of diagnosis was 80.9%. The accuracy in differentiating early gastric cancer from advancing gastric cancer was 87.5%. The correct rate for judging invasive depth of stomach wall by gastric cancer was 82.9%. It can also show the distinct ultrasonic features for gastric submucosal diseases.

Human tissue factor pathway inhibitor (TFPI) is a member of the Kunitz-type serine protease inhibitor family, which is divided into TFPI-1 and TFPI-2. The key function of TFPI-1 is anticoagulate, while TFPI-2 is a broad-spectrum serine protease inhibiter. Both of them are composed of three repeated Kunitz-type domains. Even though sharing some structural homology, they are quite different from each other in terms of the coding sequences, tissue origins and distribution, the functions and the mechanisms involved. These differences between TFPI-1 and TFPI-2 lead to the discrepancies in the roles they played in a variety of physiological and pathological processes. The recent progress in the related research is reviewed in this article.
