The paper summarized the explorations of public hospital pilots in the compensation mechanism and identified the following findings.For example,by means of fiscal support of public hospital infrastructure and development spending,cancellation of drug markup,higher service prices, and reformed payment mode of medical insurance,these hospitals have made initial changes at their business operating mechanism, motivation-guidance of compensation, and their makeup of medical revenue.In addition,such hospitals are found with lower cost of medical care per visit,and higher income of medical workers.The authors also pointed out such problems as inflated drug pricing and expenses,lack of scientific pricing mechanism for medical services,vague definition of policy-related losses,and old-fashioned practice of government investment and health insurance payment.Based on such findings,the paper advised to adjust health care prices by stages and to improve the management of health insurance and the coherence of compensation mechanism.

ObjectiveTo demonstrate the project scope of the afferent nerves of the lumbar intervertebral disc,on which basis to explore the mechanism of the symptoms of discgenic low back pain.MethodsThirty Wistar rats were divided randomly into three groups of 10 rats each:the L4-5,L5-6,and L6 S1 group.Each group was further divided randomly into two subgroups,the experimental group and the control group,5 rats for each group.Intervertebral disc was exposed through the posterior approach under peritoneal cavity anesthesia,after the nerve roots were pull away,2 μl of 30％ cholera toxin-horseradish peroxidase (CT-HRP) was injected into the inner layer of the intervertebral disc in the experimental group,while 2 μl of 0.9％ Nacl was used in the control group.Forty-eight hours after the surgery,all rats were perfused and bilateral dorsal root ganglions(DRGs) of T10-L3 were resected and fixxied.Each DRG was sectioned at 30 μm thickness and processed by DAB method.The sections of DRGs were coverslipped and observed by optical microscopy for the neurons or axons labelled by CT-HRP.It was judged as positive that brownish-black particles were in the neurons or axons.ResultsNot in a single dorsal root ganglions,but in a scope of dorsal root ganglions axons labled by CT-HRP could be seen in the rats in the experimental groups.No CT-HRP labled neurons or axons were seen in dorsal root ganglions in the contral groups.ConclusionAfferent nerves of the lumbar intervertebral disc project to a scope of dorsal root ganglions,which is the anatomic basis of the mechanism of the symptoms of discgenic low back pain.

Objective to investigate the feasibility and outcomes of different surgical treatments for adrenal metastasis after previous radical ne-phrectomy for patients with renal cell carcinoma. Methods A total of 18 adrenal solitary metastasis of renal cell carcinoma were identified from da-tabase of two institutions between 2003 and 2013. Clinical and pathologic data were collected and analyzed. Results Of 9 patients who had ipsilater-al metastasis of the renal tumor,the estimated blood loss were obviously fewer in the transperitoneal LA group. Of 9 cases who had contralateral me-tastasis of the renal tumor,the fasting time[(1.4±0.8)h vs(4.0±1.4)h,P = 0.036]and length of hospital stay[(4.5±1.2)d vs(7.0±4.5)d,P =0.041]were obviously fewer in the retroperitoneal LA group. the averages of the fasting time and length of hospital stay in the retroperitoneal LA group were obviously smaller than in the transperitoneal LA group. Conclusion LA for treatment of renal cell carcinoma metastasis is technically feasible in selected patients. transperitoneal and retroperitoneal LA can be respectively recommended as an appropriate approach for isolated adrenal metastases of ipsilateral and contralateral renal cell carcinoma after nephrectomy.

Objective To explore the adeno-associated virus (AAV)gene transduction and cellular endocytosis mediated by ultrasound combined with microbubbles in two types of cells.Methods HeLa and NIH/3T3 cells were infected by rAAV2-EGFP at a concentration gradient to get the optimal concentrations for enhancement.At these concentrations,HeLa and NIH/3T3 cells were infected by rAAV2-EGFP mediated by ultrasound combined with microbubbles.The gene transduction efficiency were observed and measured by fluorescence microscopy and flow cytometry at 48 h after treatment.The cell viability was tested by CCK-8.The number and distribution of cellular clathrin-coated endocytic pits were observed by confocal fluorescence microscopy and transmission electron microscopy on 45 min after treatment.Results The optimal concentrations for HeLa and NIH/3T3 cells were 2000 v.g./cell and 10000 v.g./cell.Ultrasound combined with microbubbles significantly enhanced the transduction efficiency of rAAV2-EGFP (P <0.01) without significant cell viability decrease (P > 0.05 ).Confocal fluorescence microscopy and transmission electron microscopy demonstrated that clathrin-coated endocytic pits were more obviously increased in ultrasound combined with microbubbles mediated AAV transduction group than AAV transduction group. Conclusions Ultrasound combined with microbubbles can efficiently enhance the gene transduction of AAV,whose cellular transportation depends on cellular endocytosis,in two types of cells.Stimulating cellular endocytosis might be one of the mechanisms of enhanced cellular transportation of AAV mediated by ultrasound combined with microbubbles.

Objective To appraise the safety and validity of early enteral nutrition on the course on treating severe acute pancreatitis(SAP).Methods The clinical data of 71 patients with SAP were analyzed retrospectively. The album, prealbumin, TNF-β,CD4/CD8,IgG were observed. All the patients were randomly divided into two groups: enteral nutrition(EN)group for 36 patients and total parenteral nutrition(TPN)group for 35 patients. Results Fourteen days after treatment,CD4/CD8 and IgG in EN group were significantly increased than those in TPN group(P＜0.05),and prealbumin level in EN group significantly elevated(P＜0.05)and was higher than that in TPN group(P＜0.05).After treatment,TNF-α level in EN group significantly depressed(P＜0.05)and was lower than that in TPN group(P＜0.05).Conclusion Early enteral nutrition is safe and valid, and can promote albumin synthesis and prealbumin levels to improve their nutrition in patients with SAP, and may build-up the barrier of enteric mucosa to prevent bacterial shift, reduce systemic inflammatory reaction and improve its prognosis.

This study was aimed to improve the sensitivity of magnetic induction phase shift detection system for cerebral hemorrhage. In the study, a cerebral hemorrhage model with 13 rabbits was established by injection of autologous blood and the cerebral hemorrhage was detected by utilizing magnetic induction phase shift spectroscopy (MIPSS) detection method under the feature band. Sixty five groups of phase shift spectroscopy data were obtained. According to the characteristics of cerebral hemorrhage phase shift spectroscopy under the feature hand, an effective method, B-F distribution, to diagnose the severity of cerebral hemorrhage was designed. The results showed that using MIPSS detection method under feature band, the phase shift obviously growed with increase of injection volume of autologous blood, and the phase shift induced by a 3-mL injection reached -7.750 3 degrees ± 1.420 4 degrees. B-F distribution could effectively diagnose the severity of cerebral hemorrhage. It can be concluded that the sensitivity of the cerebral hemorrhage magnetic induction detection system is improved by one order of magnitude with the MIPSS detection method under the feature band.
