The aim of the present paper intends to explore the international experiences of healthcare profes-sional organizations and its enlightenment for China. The functions of health professional organizations in advanced countries include certification and accreditation, self-discipline, academic exchanges, political participation, service for industry, member rights protection and so on. The legal authorization, comprehensive supervision and competitive market mechanisms which make sure these functions perform well are worth learning for China.

This article is based on a questionnaire survey of healthcare professional organizations and interview leaders of them. The results of this investigation show that the number of staff is small, and lack of highly qualified human resources. The organizations rely on donation for income and some of them run at a deficit. The functions such as professional self-discipline are not well performed. The analysis reveals four reasons why functions are not well per-formed:the bureaucratic style of the professional organizations and unclear legal status;the limited authorization from legal and administrative bodies;the defects in the governance system and the lack of capacity. Four aspects of policy recommendations are were proposed: to clearly define the role of the professional organizations and authorization through legal and administrative procedures; to strengthen support of professional organizations through various poli-cies;to improve governance and build comprehensive regulation mechanisms;to enhance the capacity of these organi-zations and so on.

The characteristics of health care require that health care professional organizations play an impor-tant role in health governance. The role of health care professional organizations in China has not been clearly defined and their functions have not been fully developed. This paper explores the nature, and the functions of health care professional associations in China. Based on the analysis of health governance characteristics in China, the role, and functions of the health care professional organizations in China’s health governance were defined and relevant policy recommendations are were proposed.

To prepare virus-like particles containing FluA/B mRNA as RNA standard and control in Influenza RNA detection, the genes coding the coat protein and maturase of E. coli bacteriophage MS2 were amplified and cloned into D-pET32a vector. Then we inserted 6 histidines to MS2 coat protein by QuikChange Site-Directed Mutagenesis Kit to construct the universal expressing vector D-pET32a-CP-His. In addition, the partial gene fragments of FluA and FluB were cloned to the down-stream of expressing vector. The recombinant plasmid D-pET32a-CP-His-FluA/B was transformed to BL21 with induction by IPTG. The virus-like particles were purified by Ni+ chromatography. The virus-like particles can be detected by RT-PCR, but not PCR. They can be conserved stably for at least 3 months at both 4 degrees C and -20 degrees C. His-tagged virus-like particles are more stable and easier to purification. It can be used as RNA standard and control in Influenza virus RNA detection.

Objective To assess the safety and efficacy of adopting different vascular access during autologous peripheral blood stem cells collection.Methods 87 patients received autologous peripheral blood stem cells collection were divided into two groups:One was peripheral vein harvesting group (43 cases),which used the 16G disposable fistula needle for autolo-gous peripheral blood stem cell collection and the other central venous harvesting group (44 cases),which used double cavity of femoral vein catheter for autologous peripheral blood stem cell collection.The observation indicators included venous ac-cesses,collection efficiency,patient tolerance,the number of mononuclear cell and CD34 positive cells.Results The numbers of mononuclear cells and CD34 positive cells in two groups were all above the standard and there was no significant differ-ence (P >0.05).However,the success of venous accesses,the efficiency smooth of collection and-patient tolerance were bet-ter in double cavity of femoral vein catheter group (P <0.05).Conclusion Harvesting the autologous peripheral blood stem cell through central venous by using double cavity of femoral vein catheter had the advantages as follows:high success rate of puncture,acquisition smoothly and reducing the suffering extent of the patients,and also it did not affect the acquisition effi-ciency and effectiveness.

BACKGROUND:Spinal canal decompression is needed in posterior pedicle screw fixation surgery for thoracolumbar burst fractures combine with spinal cord injury. The structure of posterior spine is often damaged. The posterolateral bone fusion in al fixed segment is stil the main surgery. In order to further reduce fusion segment and maintain motor unit, it is necessary to perform selective segmental bone graft fusion during fixation and decompression.
OBJECTIVE: To discuss the advantages of selective posterolateral vertebral fusion for thoracolumbar fracture with spinal injury through comparing with posterolateral vertebral fusion.
METHODS: Data of 83 thoracolumbar burst fracture cases, who received posterior lumbar decompression and short segment fixation with pedicle screws and bone graft through injured vertebra from January 2006 to July 2013, were analyzed retrospectively. According to fusion segments, above patients were divided into selective posterolateral vertebral fusion group (n=42) and the whole posterolateral vertebral fusion group (n=41). Perioperative index, internal fixation, vertebral height loss rate, Cobb angle, spinal nerve recovery and Oswestry Disability Index were compared between the two groups.
RESULTS AND CONCLUSION:(1) Al cases were folowed up for 25-32 months. (2) There was no statistical significance in operation time, intraoperative blood loss and ambulation time between the two groups (P > 0.05). Postoperative drainage volume was less in the selective posterolateral vertebral fusion group than in the whole posterolateral vertebral fusion group (P < 0.05). Before removal of fixator, there was no loosened fixator or breakage of screw or stick. (3) There were improvements in the rate of vertebral front height loss and Cobb angle in both groups at various time points after operation (P < 0.05). There was no statistical significance in the rate of vertebral front height loss and Cobb angle in both groups (P > 0.05). (4) There was no significant difference in fusion rate at 6 months after treatment between the two groups (P > 0.05). Fusion was achieved in both groups before removal of the fixator. (5) Spinal nerve recovery was found after treatment in both groups. No significant difference in Oswestry Disability Index was detected in final folow-up (P > 0.05). (6) Results verified that compared with the whole posterolateral vertebral fusion, selective posterolateral vertebral fusion can obtain a good vertebral height and prevent Cobb angle loss again, reduce the internal fixation loosening and breakage. After removal of the fixator, selective posterolateral vertebral fusion can reduce spinal motion unit lost, and decrease the adjacent vertebral degeneration.

BACKGROUND:Human amniotic epithelial cells have some properties of stem cells, which can be induced to differentiate into corneal epithelial cells, but cannot be tracedin vitro. OBJECTIVE:To investigate the feasibility and infection efficiency of adenovirus vector carrying enhanced green fluorescent protein (EGFP) into the human amniotic epithelial cells. METHODS:The adenovirus vectors carrying EGFP was transferred into human amniotic epithelial cells culturedin vitro. After cultured and amplified, the morphology difference between transfected and non-transfected human amniotic epithelial cels was observed. The transfected human amniotic epithelial cells were observed under fluorescence microscope, and the cell cycle and the expression rate of EGFP in transfected human amniotic epithelial cells were detected by flow cytometry. RESULTS AND CONCLUSION:No obvious difference in the cell morphology was found between transfected human amniotic epithelial cells and normal human amniotic epithelial cells cultured in vitro. Flow cytometry analysis revealed that the EGFP positive rate was highest and reached up to 99.01% at 48 hours after transient transfection. The cell cycle of human amniotic epithelial cells transfected by the adenovirus vector was slowed a bit. To conclude, the adenovirus vector is a good medium of transfecting EGFP into human amniotic epithelial cells, and makes it more convenient to observe the further transformation of human amniotic epithelial celsin vitro.
