BACKGROUND: It is difficult to revise replacement due to infection-induced osteodeficiency, osteoporosis, soft tissue lost orcicatrization.OBJECTIVE: To establish the standardized clinical prevention and treatment methods by summarizing the new progress to prevent, diagnosis of the infection, and its effective treatment, as well as rehabilitation evaluation after total Knee replacement. METHODS: A computer-based online search of CNKI and PUBMED database between January 1990 and December 2010 was performed to search related articles with the key words of total knee arthroplasty, infection. A total of 2 346 articles were retrieved. Moreover, related works were manually searched. Totally, 30 articles were included.RESULTS AND CONCLUSION: It is better to prevent infection rather than treatment after total knee replacement. Currently, there is lack of a clear diagnosis standard on the infection. In treatment aspect, debridement, revision surgery, and choosing effective antibiotics can effectively control the infection. Meantime, new methods are expected to improve the success rate of infection after total knee replacement. Exercise is a continuation of rehabilitation therapy and an important step in treatment. Therefore, on the basis of total knee replacement, it is important to establish the early prevention of postoperative infection, early diagnosis, effective treatment and rehabilitation evaluation system, in order to minimize the incidence of infection and treat infections timely and effectively.

Objective To observe the effects of Ganlu Xiaodu Dan and its incomplete prescription on expressions of MiR-146a and TLR4 mRNA in RD cells infected by EV71. Methods With technique of cell culturing, Ganlu Xiaodu Dan therapy group, incomplete Qing prescription therapy group, incomplete Li prescription therapy group, normal cells control group, model control group and ribavirin control group were set, and tests for virus toxicity and medicine toxicity in cells were taken, then expressions of miRNA-146a and TLR4 mRNA in these RD cells 24 hours after intervention with medicine were detected. Results Compared with normal cells control group, miR-146a in mRNA model control group decreased and TLR4 mRNA increased. Compared with model control group, miR-146a mRNA in Ganlu Xiaodu Dan therapy group, incomplete Qing prescription therapy group and incomplete Li prescription therapy group all increased while TLR4 mRNA decreased, and differences between ribavirin control group and model control group were not significant. Compared with Ganlu Xiaodu Dan therapy group, both expressions of miR-146a and TLR4 mRNA in incomplete Qing prescription therapy group were lower; miR-146a increased and TLR4 mRNA decreased in incomplete Li prescription therapy group. Compared with incomplete Qing prescription therapy group, miR-146a mRNA in incomplete Li prescription therapy group increased, but expression of TLR4mRNA between them was not significant. Conclusion Ganlu Xiaodu Dan can regulate the immune reactions caused by infection of EV71 by increasing expression of miR-146a mRNA and reducing expression of TLR4 mRNA. There may be antagonism effect between incomplete Qing prescription and incomplete Li prescription.

Results In inhibiting-virus-directly experiment, therapeutic-inhibiting-virus experiment and preventive-therapeutic-inhibiting-virus experiment, virus inhibition rate of Ganlu Xiaodudan was higher than ribavirin. In preventive-inhibiting-virus experiment, virus inhibition rates of Ganlu Xiaodudan and ribavirin both were almost zero. Conclusion Ganlu Xiaodudan has better antiviral effects on EV71 than ribavirin, and it can affect more than one link of multiplication of EV71.

BACKGROUND:In order to avoid heterotopic ossification after total hip arthroplasty, nonsteroidal anti-inflammatory drugs are commonly used for prevention.
OBJECTIVE:To compare the effect of meloxicam and indomethacin in the prevention of heterotopic ossification after total hip arthroplasty.
METHODS:Fifty-one patients who treated in the Department of Orthopedics, the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine from 2010 to 2011 were col ected. Among the 51 patients, nine patients were treated with bilateral total hip arthroplasty, and al the patients had total hip arthroplasty with the posterior-lateral approach. The patients were divided into the control group and the experimental group according to the drugs used after replacement, and the patients in the two groups were administered with indomethacin sustained-release tablet 25 mg+omeprazole capsule 20 mg or meloxicam tablet 15 mg after replacement.
RESULTS AND CONCLUSION:There were no significant differences in the incidence of heterotopic ossification, pain, modified D’Aubigne and Postel scores after replacement between two groups (P>0.05). But, the gastrointestinal adverse reactions of the experimental group were less than those of the control group. The application of meloxicam only can effectively avoid the heterotopic ossification and release pain. Consequently, we recommend meloxicam as postoperative drug for the prevention of heterotopic ossification and pain remission fol owing total hip arthroplasty.

Methods Model of myocardial IRI was established in rats. BMSCs were isolated, cultivated, and transplanted in IRI rats. SD rats were randomly divided into sham-operation group, IRI group, BMSCs group, and combined group. Rats in combined group received gavage with soothing liver and activating blood Chinese medicine, while rats in other groups received gavage with the same dose of normal saline. After 4 weeks, myocardial cell apoptosis, Bcl-2, and Bax protein expression in myocardial cells were detected by TUNEL method and immunohistochemical method. Results Compared with IRI group, myocardial cell apoptosis index in the combined group and BMSCs group was lower, Bax expression decreased, Bcl-2 expression significantly increased (P<0.01);Compared with BMSCs group, myocardial cell apoptosis index in the combined group was lower;Bax expression decreased, Bcl-2 expression increased (P<0.05, P<0.01). Conclusion Soothing liver and activating blood Chinese medicine can inhibit BMSCs transplantation in IRI rat myocardial cell apoptosis, promote myocardial regeneration, and protect myocardial cells.

Objective To analyze the clinical characteristics and treatment strategy of phosphaturic mesenchymal tumors in hips.Methods From May 2017 to November 2017,five patients with phosphaturic mesenchymal tumors in hips,who treated in our hospital were retrospectively reviewed.The clinical manifestations,laboratory inspection,radiological examination,pathological examination and treatment were analyzed.Results Two male cases (40％) and 3 female (60％) were included.The overall age was 49～63 years old (average 54.40±5.37 years old).The course was 19～101 months (average 51.20±32.41months).Four cases of tumor were located in femoral head and 1 case was in femur intertrochanteric region.The maximum tumor diameter was 0.76～1.83 cm (average 1.28±0.39 cm).The early clinical manifestations of the patients were mainly non-specific bone pain or fatigue.The symptoms of the hip were not obvious.All patients had been misdiagnosed.After pathological frac-ture of the hip,the patient suffered from hip pain,thigh pain,fatigue,etc.,or limited hip function.The severe patients had a systemic multiple pathologic fractures.The serum phosphorus was lower than normal in preoperative period and recovered to normal level in 3-8 days after surgery.The postoperative ALP decreased significantly than preoperative in 4 patients and 1 case was slightly higher than preoperative.Preoperative 1,25-(OH)2-D3 and PTH were in normal range.99Tcm-octreotide (OCT) scan or 68Ga DOTA-TATE PET/CT can detect the disease.X-ray,CT and MRI can identify the lesions.The lesions of femoral head were basically under the joint surface,with a nodular change.Part of the tumor was infiltrating and close to the cortex.The pathology was mainly manifested as a large number of thin-walled vessels in the bone trabeculae.There were dense spindle cells or astrocytes between the blood vessels and the atypia is not obvious.Three patients were treated with total hip arthroplasty and two with segmental resection and bone graft.After surgical removal of the tumor,the patient's systemic pain or anemic symptoms were gradually relieved and the joint function was restored.Meanwhile,the bone density was increased.Conclusion The clinical features of the phosphaturic mesenchymal tumors in hips were not obvious.Comprehensive diagnosis should be carried out in combination with the clinical manifestations,laboratory examination,radiological examination and pathological examination.Total hip arthroplasty or segmental resection with bone graft can effectively remove the tumor and achieve good prognosis.

Objective To investigate a self-designed catheter pump by using computational fluid dynamics (CFD) method, so as to predict its hydraulic performance and risk of thrombosis formation. Methods The thrombosis prediction models proposed by Grigioni and Danny Bluestein were used. The shear stress and exposure time during platelet motion were calculated by CFD method, and parameters of platelet activation state (PAS) were obtained for prediction of thrombogenic performance. Results At the flow rate of 4 L/min and rotating speed of 10 000 r/min, the differential pressure of the pump reached 14.763 kPa and the hydraulic performance was proved to fit the requirement of left ventricular assist device. The PAS values of Grigioni model and Danny Bluestein model were 6.35×10-6 and 7.68×10-4,respectively, both at a very low level, indicating a low possibility of thrombus formation. Conclusions This study investigated the feasibility of thrombosis prediction based on simulation method and the predicted hydraulic performance and thrombosis will provide references for further design optimization.
