A total of 118 patients (138 knees) who received total knee arthroplasty at the Department of Orthopedics, Guizhou Province People's Hospital between June 2000 and January 2007 were included in this study. These patients comprised 45 males and 73 females and were averaged (61±8) years old (range, 52-81 years). Of them, 28 (34 knees) suffered from rheumatoid arthritis, 6 (6 knees) from traumatic arthritis, 84 (98 knees) from severe osteoarthritis, 14 (18 knees) complicated by extraversion, and 25 (28 knees) complicated by inversion. Link Gemini knee prosthesis was used in 38 knees, Zimmer Nexgen knee prosthesis in 68 knees, and Depuy pfc sigma rotation platform knee system in 32 knees. All patients were followed up for an average of 28 months (range, 10 months-6 years). Prior to replacement, the mean knee score, according to the Hospital for Special Surgery (HSS) rating scale, was (34.00±7.65) points, and at the latest follow-up examination, it was (81.00±6.89) points. HSS score was excellent in 87 knees (63%), good in 43 knees (31%), and fair in 8 knees (6%). The excellent and good rate was 94%. Of 118 patients, 4 presented with infection and 3 showed deep venous thrombosis in lower limb following unilateral total knee arthroplasty and healed after anticoagulation and symptomatic therapy. There were 3 patients presenting with knee joint pains 2 months following knee joint arthroplasty. No knee joint red swelling and tenderness were found. Range-of-motion was basically normal. X-ray photograph indicated good position of prosthesis. Pains were relieved after femoral nerve block. All these findings suggest that total knee replacement is an effective method of treating severe knee joint diseases. INTRODUCTIONTotal knee arthroplasty (TKA), as an important part of artificial joint replacement for treatment of severe knee joint diseases, initiated from the first knee joint prosthesis developed by Cunstno in 1960s and was put in use. But following TKA, large-scale severe complications appear due to condition limitations, which results in failed surgery. With development of molecular biology and materials, as well as further research of installing technique and knee joint biomechanics, TKA has been shown to be gradually perfect theoretically. A novel prosthesis better corresponds to the physiological standards of human body in terms of structure design, material strength, and shape. These improvements greatly enhance prosthesis survival rate and markedly decreases complication incidence following TKA. TKA has been shown to be an efficient method of treating severe knee joint diseases. It can effectively relieve joint pains and improve joint functions, and is mostly used in elderly populations (over 60 years old) who complicated by other diseases, such as diabetes mellitus, hypertension, heart disease, phlebitis of lower extremities. In addition to above-mentioned, poor body resistance enhances surgery risk and difficulties, and complications would be correspondingly increased following TKA. The present study retrospectively analyzed a total of 118 patients with severe knee joint diseases who underwent TKA at the Department of Orthopedics, Guizhou Province People's Hospital between June 2000 and January 2007.

Objective:To evaluate the effects of erythropoietin (EPO)on the proliferation and osteogenic differentiation of human dental pulp cells(hDPCs)in vitro.Methods:Isolated hDPCs were cultured and identified.The cells were treated by EPO and the proliferation of the cells was determined by CCK-8 assay.After incubation with EPO at 20 U /ml in osteogenic induction medium for 7 and 1 4 days,the mineralization of hDPCs was observed by alkaline phosphatase (ALP)activity assay and alizarin red staining.Real-time PCR was utilized to detect the expression of odontogenesis-related genes.Results:EPO enhanced the proliferation of hDPCs in a time-and dose-dependent manner.After treatment with EPO,ALP activity and the minerialized nodes of the cells increased(P <0.05);the expression levels of odontogenesis-related genes DSPP,OCN,OSTERIX and RUNX2 were upregulated(P <0.05).Con-clusion:EPO can promote proliferation and differentiation of human dental pulp cells.

Stage Ⅲ A non-small cell lung cancer (NSCLC) has high heterogeneity and there are some controversies over the treatment of this disease,especially for patients with stage ⅢA-N2 NSCLC.This article investigates whether preoperative or postoperative radiotherapy can improve the survival of patients with stage ⅢA-N2 NSCLC and evaluates the effect of surgical treatment.

From 101 records relating to health kept in the National Archives of Malaysia for the period 1946–1981, 30 records were chosen using purposive criterion-based sampling on dimensions of universal health coverage (UHC) and health system governance. From those 30, document review was performed on 13 records that were selected based on relevance to analysis of the evolution of private and public health institutions and their roles in achieving UHC from 1946 to 1981. UHC relates to the ability of patients to access good quality service with high population coverage of health care at low financial risk. Malaya was a former Western Pacific nation ruled by the British colonial government. Initially, the government bore the cost of medicines and passages between the United Kingdom and Malaya for Red Cross and St. John’s ambulance teams to serve in rural areas in Malaya. This was later replaced by home grown Rural Health Teams trained in purpose built Rural Health Centres beginning with the first such training school in Jitra under the Rural Health Scheme. The Rural Health Scheme was implemented from 1953 to 1956 and marked an ambitious period of utilising limited resources to expand human resource and establish District Health Centres, Sub-District Health Centres, Midwives’ Houses and Maternal and Child Health Centres across the rural landscape of Malaya. After analysis, it was found that the British colonial government’s efforts in improving public health through the Rural Health Scheme had provided the foundation for achieving UHC in Malaysia today.
