Objective:To analyze the mechanism on integration of health care services at the county and town-ship level from the perspective of stakeholder theory. Methods: The stakeholder interest demand was determined by word frequency analysis of interview data from stakeholders in the three regions of Qianjiang, Huangpi, and Zhen-jiang;the degree of attention and gains and losses of stakeholders towards various demands was investigated from the three regions through interest demand questionnaires;the impact of demand benefits on behavioral responses has been evaluated through comprehensive evaluation theory and game theory. Results:Regional integration policies reflect the interest demands of stakeholders in varying degrees; the higher were the scores of demand benefits in interest de-mands questionnaires, the stronger was the willingness of stakeholders to coordinate integration policies. Conclusion:The policies of integration of health care services in rural China should consider all stakeholder interest demands;the better the interest demands of the stakeholders are satisfied, the stronger their motivation for integration reform will be, which may affect the implementation effects of local integration reforms to some extent.

To study the cartilage differentiation of mouse mesenchymal stem cells (MSCs) induced by cartilage-derived morphogenetic proteins-2 in vitro, the MSCs were isolated from mouse bone marrow and cultured in vitro. The cells in passage 3 were induced into chondrogenic differentiation with different concentrations of recombinant human cartilage-derived morphogenetic proteins-2 (0, 10, 20, 50 and 100 ng/mL). After 14 days of induction, morphology of cells was observed under phase-contrast microscope. Collagen II mRNA and protein were examined with RT-PCR, Western blotting and immunocytochemistry respectively and the sulfate glycosaminoglycan was measured by Alcian blue staining. RT-PCR showed that CDMP-2 could promote expression of collagen II mRNA in an dose-dependant manner, especially at the concentration of 50 ng/mL and 100 ng/mL. Immunocytochemistry and Western blotting revealed a similar change. Alcian blue staining exhibited deposition of typical cartilage extracellular matrix. Our results suggest that mouse bone marrow mesenchymal stem cells can differentiate into chondrogenic phonotype with the induction of CDMP-2 in vitro, which provides a basis for further research on the role of CDMP-2 in chondrogenesis.

Objective To summarize the clinical features,diagnostic and treatment experience of severe hand,foot and mouth disease(HFMD) cases receiving mechanical ventilation from Jan 1 to Sep 6,2009 in our hospital and provide reference for reducing the occurrence of neurogenic pulmonary edema(NPE) and mortality. Methods 147 severe HFMD who received mechanical ventilation were analyzed by a retrospective investigation. Results 85.0% children were less than 3 years old and 100% patients had a fever. The mechanical ventilation occurred within 1 to 4 days after fever (3.06 ± 1. 02) d. Neurological complications presented as bad spirit,easy surprised, involuntary movement of the extremities and lethargy. Respiratory system complication presented as polypnea, hypepnea and irregular rhythm. Circulatory system complication presented as heart rate increase or decrease, hypertension or hypotension, piebald skin and low limb temperature.Some of the children had high white blood cell counting,glucose and lactic acid of the blood. The EV71-PCR positive rate was 34. 7% for throat swabs,and 42. 2% for anal swabs. Chest X-ray presented as increased broncho vascular shadows, exudation or nonapparent abnormality. Only three children were dead, fatality rate was 2. 0%. Conclusion The HFMD cases in this outbreak are relatively more serious,and change rapidly. It's difficult to treat as soon as NPE appeared,and it has high fatality rate. Early recognition of critical patients,timely giving mechanical ventilation,and the comprehensive treatment can reduce NPE incidence and the mortality.

Objective In clinical practice,ultrasound-guided fine-needle aspiration biopsy (US-G FNAB) is the gold standard in diagnosing the pathological nature of undetermined thyroid nodules before operation.Re---sults of FNAB may vary substantially among operators with different skills.The aim of this study is to evaluate whether operator experience in US-G FNAB influences the rate of diagnostic procedures.Methods A total of 600 consecutive US-guided FNAB done by a single radiologist with 22-or 27-gauge needles from Feb.2008 to Apr.2012 were retrospectively analyzed.All specimens were prepared and fixed without the cytologist on site and were subsequently analyzed by 2 expert cytologists.The procedures were chronologically divided into 6 groups and further stratified according to the overall (A),solid nodules (B),mixed nodules (C),pure cystic nodules (D),acellular sample(E),heavily blood-stained sample(F),exclusively colloid material(G),incorrect slide fixation(H) and they were classified as diagnostic or no-diagnostic.Results The rate of no-diagnostic procedures for each group in learning curves were reported as:① Among A,34% in group 1,15% in group 2,18%in group 3,10% in group 4,7% in group 5,and 8% in group 6.② Among B,4% in group 1,1% in group 2,0% in group 3,0% in group 4,0% in group 5,and 0% in group 6.② Among C,10% in group 1,1% in group 2,4% in group 3,0% in group 4,1% in group 5,and 0% in group 6.④ Among D,20% in group 1,13% in group 2,14% in group 3,10% in group 4,6% in group 5,and 8% in group 6.⑤ Among E,25% in group 1,15% in group 2,15% in group 3,10% in group 4,6% in group 5,and 8% in group 6.⑥ Among F,4% in group 1,0% in group 2,1% in group 3,0% in group 4,0% in group 5,and 0% in group 6.⑦ Among G,1% in group 1,0% in group 2,1% in group 3,0% in group 4,1% in group 5,and 0% in group 6.⑧ Among H,4% in group 1,0% in group 2,1% in group 3,0% in group 4,0% in group 5,and 0% in group 6.Among the 600 procedures,there were 2 cases of vertigo and 4 cases of moderate bleeding at the biopsy site,all of which resolved spontaneously.No major complications were recorded.Conclusions The rate of no-diagnostic US-guided FNAB is heavily dependent on the operator's experience.We estimate that at least 200 procedures are needed in order to achieve the levels of diagnostic accuracy reported in the literature.We therefore suggest operators to get specific training before routinely perform this procedure in clinical practice.
