Research on standardization of traditional Chinese medicine(TCM) is playing an important role in constructing of modernized TCM.But it is difficult to set down a diagnosis and treatment standardization of TCM and it will cost long term and arduous work.Based on clinic and scientific research in recent years,this article focuses on the standardization research of diagnosis and treatment of AIDS with TCM to discuss the content,method and some pivotal questions.

BACKGROUND:Bone cement has certain toxic effects on the human body. The probability of renovation is high after bone cement total hip arthroplasty. It is reported that the long-term effect of cementless total hip arthroplasty is apparently better than bone cement total hip arthroplasty, and can be renovated conveniently. OBJECTIVE:To investigate the clinical effect of cementless total hip arthroplasty on hip joint disease, and to compare the difference between unilateral replacement and bilateral replacement. METHODS: Clinical and folow-up data of 233 patients (280 hips), who were treated with cementless total hip arthroplasty in the Department of Orthopedics, Wuzhou Worker’s Hospital, Seventh Affiliated Hospital of Guangxi Medical University from July 2007 to December 2013, were retrospectively analyzed. According to the replacement program, they were divided into unilateral replacement group (n=186) and bilateral replacement group (n=47). Harris score of hip joint, visual analog scale score of thigh pain, the excelent and good rate of hip joint during final folow-up and complications were compared between the two groups before replacement, at 6, 12 and 24 months after replacement. RESULTS AND CONCLUSION:No significant difference in Harris scores was detected before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Harris score was significantly higher at 6, 12 and 24 months after replacement compared with that before replacement in both groups (P < 0.05). No significant difference in the excelent and good rate was detected in the unilateral replacement group (87%) and the bilateral replacement group (86%) (P > 0.05). No significant difference in the visual analog scale score was seen before replacement, at 6, 12 and 24 months after replacement (P > 0.05). Visual analog scale scores were significantly lower at 6, 12 and 24 months after replacement than that before replacement in the two groups (P < 0.05). There was no significant difference in the incidence of complications after replacement in patients of both groups (P > 0.05). These findings confirm that the effects of cementless total hip arthroplasty for hip joint disease are evident, can effectively restore hip joint function. No significant difference was detected between unilateral replacement and bilateral replacement. Strict replacement operation and matching of prosthesis and medulary cavity can effectively reduce thigh pain after replacement.

BACKGROUND:Clinical infusion of hematopoietic stem cells and mesenchymal stem cells for treatment of aplastic anemia has been reported. OBJECTIVE:To investigate the effect of human adipose-derived mesenchymal stems cells on the secretion function of T lymphocytes of aplastic anemia patients. METHODS:Human adipose-derived mesenchymal stems cells were extracted from healthy human adipose tissues. T-lymphocytes were harvested from peripheral blood of patients with aplastic anemia by density gradient centrifugation. Human adipose-derived mesenchymal stems cells were co-cultured with T-lymphocytes. The levels of interleukin-2, interleukin-4, interleukin-10 and interferon-γwere detected by enzyme linked immunosorbent assay. T-bet and GATA-3 levels were examined by real-time PCR and western blot. RESULTS AND CONCLUSION:The levels of Th1 type cytokines interferon-γand interleukin-2 in the co-culture group were significantly lower than those in the T-lymphocyte group (P<0.05). But the levels of Th2 type cytokines interleukin-4 and interleukin-10 in the co-culture group were significantly higher than those in the T-lymphocyte group (P<0.05). The T-bet mRNA and protein levels in the co-culture group were significantly lower than those in the T-lymphocyte group, while the GATA-3 mRNA and protein levels were significantly higher in the co-culture group. Human adipose-derived mesenchymal stems cells can mediate an immunoregulation effect on T-lymphocytes of aplastic anemia patients in vitro, which is possibly related with the inhibition of Th1-dominant response due to the disorder of T-bet and GATA-3 gene expression.
