Objective To put forward a reform assumption of physician payment model based on review of physician payment models abroad. Methods Literature review and expert interview. Results Physician payment model and its reform patterns overseas were discussed. Problems of current physician payment model in Chinese public hospitals were analyzed. Conclusions The physician payment reform in public hospitals should focus on raising physician salary. The investment of resources and technology of medical service projects should be measured reasonably. Setting up responsibility center , saving health care costs and improve the quality of health care are the most important three aspects of physician payment model reform in Chinese public hospitals.

Objective To evaluate the feasibility and clinical effect of stage Ⅰ posterior vertebral corpectomy filled with titanium mesh cages plus long-segmental instrumentation for treatment of Denis type D and E severe unstable thoracolumbar burst fracture.Methods A retrospectively review was made on 14 patients with Denis type D and E severe unstable thoracolumbar burst fracture,having had posterior vertebral corpectomy,titanium mesh bone grafting and long-segmental pedicle screw fixation.Parameters recorded were operation time,amount of bleeding,bone fusion and reduction,postoperative complications,low back pain,neurological performance,restoration and loss of anterior vertebral height,correction and loss of kyphosis,and intraspinal space occupying lesion.Results Mean operation time was 207.1 min (range,148-306 min) and blood loss was 585 ml (range,300-1,500 ml).Intraoperative fracture reduction was satisfactory.Follow-up ranged from 18 to 54 months (mean,28 months),which showed no complications of infection,screw-rod breakage,loosening or shifting of the internal fixation device,titanium mesh subsidence and pseudarthrosis,and no signs of adjacent segment degeneration.Six months after operation,CT scan showed bony fusion of the bone-implant interface.At the final follow-up,the Denis pain scale improved significantly including 12 patients with completely relieve of pain (P1) and 2 ache slightly but no need of taking painkiller (P2).Neurological functions were improved by 1-3 degree in all patients.Percentage of anterior vertebral height was (41.2 ± 8.9)% before operation,significantly reduced to (8.3 ± 4.8) % one week after operation and to (8.9 ± 5.1) % at the final follow-up (P <0.01).Mean loss of anterior vertebral height was 0.6%.Sagittal kyphotic angle was (36.9 ± 4.9) °before operation,significantly reduced to (8.1 ± 3.4) ° one week after operation and (8.5 ± 3.8) °at the final follow-up (P <0.01).Mean loss of kyphotic angle was 0.9°.Ratio of intraspinal space occupancy was (74.9 ± 11.3) % before operation but recovered to (4.1 ± 1.6) % one week after operation and (1.8 ± 1.4) % at the final follow-up,with significant differences in pair comparison (P < 0.01).Conclusion The use of posterior vertebral corpectomy and fusion with titanium mesh cage fusion in conjunction with long-segment instrumentation are effective for spinal canal decompression,fracture reduction,three-column reconstruction as well as rigid fusion at one stage,lumbar pain relief,neurological function recovery,prevention of correction loss and vertebral height restoration.

Objective To explore the expression levels of RAS-interacting protein 1 (RASIP1) mRNA and protein in hepatocellular carcinoma (HCC) tissues and its cell lines,and to analyze the relationship between RASIP1 and tumorigenesis and progression of hepatocellular carcinoma.Methods The expression levels of RASIP1 mRNA and protein in 29 hepatocellular carcinoma tissues and the corresponding adjacent non-cancer liver tissues (ANLTs),as well as those in the HCC cell lines such as LO2,HEPG2,MHCC97-H and HCCLM3 were detected using real-time PCR and western blot.Results The RASIP1 expression levels decreased significantly in HCC tissues when compared with the corresponding ANLTs; The expression levels of RASIP1 mRNA and protein in LO2 were significantly higher than those in other HCC cell lines (P < 0.05) ; The expression levels of RASIP1 mRNA and protein in MHCC97-H and HCCLM3 were significantly lower than those in HepG2 (P < 0.05).Conclusions HCC tissues had lower expression than those in ANLTs.On analyzing the RASIP1 levels of HCC tissues and its cell lines,we speculated that RASIP1 might suppress recurrence and metastasis of HCC.

Objective To summarize the experience in the perioperative nursing of one-stage bilateral total hip arthroplaaty (THA) for the systemic lupus erythematosus (SLE) patients with avascular necrosis of the femoral head (ANFH).Methods From June 1998 to April 2007,17 cases of patients who were diagnosed as SLE with bilateral ANFH were treated by one-stage bilateral THA.Perioperative nursing included psychological support,diet control,observation and nursing of various complications,correct functional exercise and health education.Harris score and SF-36 score were evaluated before and after operation.Results There were 2 cases with delayed incision healing,1 with early prosthesis dislocation,1 with thigh pain for 10 months and 1 with acute renal failure postoperatively,which were improved and recovered after proper treatments.Asymptomatic deep vein thrombosis (DVT) in low extremities were detected by color Doppler ultrasonography in 6 cases.There were no pulmonary embolism and no deep infection around prosthesis.There was no Addisonian crisis postoperatively.The pain was relieved and the motion of joint was improved during follow-up.There was no radiological evidence of implant loosening.The Harris hip score and SF-36 score greatly alleviated after operation.All patients were followed up and the mean follow-up time was 28 months.Conclusions One-stage bilateral THA has good results for the patients with SLE and AVNH.Strengthening of perioperative nursing contributed to improvement of success rate of surgery and reduction of complication.

An enzyme linked immunosorbent assay ( ELISA ) and a flow cytometry assay ( FCA ) based on Wil2-S cells were developed and systematically compared for quantification of recombinant anti-CD20 humanized monoclonal antibody ( rh-anti-CD20zumab) in biological matrix. The specificity, precision and accuracy of each method at correspondingly different linear range showed good results. For ELISA, the precisions of intra-day and inter-day were both <19 . 5%, the relative error was from-18 . 2% to 17 . 6%;For FCA, the precisions of intra-day and inter-day were both <19. 0%, the relative error was from -18. 9% to 18. 4%. The sensitivity of ELISA was significantly higher than that of FCA. The quantitative ranges of ELISA and FCA methods were 0. 04-5. 0 mg/L and 3. 1-200 mg/L, respectively. The concentrations in serum samples and pharmacokinetics analysis were determined by both of two methods after vein drip administration of rh-anti-CD20zumab in rhesus monkeys. Pharmacokinetics data showed that there was excellent consistency between results obtained by two methods at the given dose. We believe that the novel FCA with high speed and high sensitivity can be used to perform PK and PD study of cell surface antigen-targeted antibody derivatives.

Objective To study the clinical effect of acupuncture therapy combining with biofeedback therapy on senile chronic insomnia patients. Methods 150 cases of senile chronic insomnia were divided into 3groups randomly: group A received acupuncture therapy only, group B received biofeedback therapy only, and group C received both therapies. The scores of Pittsburgh Sleep Quality Index (PSQI) ,sleep efficacy,sleep latency, total sleep time and the scores of Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD-17) were assessed before the treatment and at the end of the 4th and 8th week during the treatment.Results After 8 weeks treatment, the scores of PSQI, sleep efficacy, sleep latency, total sleep time and the scores of HAMA and HAMD-17 of group C((7.92 ±2.59)score,(82.52 ±8.93)% ,(24.06 ±8.23)minutes,(413.75± 42.41) minutes, (9.63 ± 3.75) score, (10.10 ± 3.27) score) were better than that of group A (( 9.51 ± 2.92)score, (79.06 ± 10.70) %, (33.16 ± 11.31) minutes, (373.47 ± 40.65) minutes, (15.08 ± 4.20) score, (14.33±± 3.56) score) and group B (( 11.46 ± 3.75) score, (68.85 ± 12.34) %, (33.65 ± 11. 38) minutes, (281.88 ±38.02) minutes, (11.63 ± 4.15) score, (12.08 ± 4.08) score) significantly (P < 0.01). Conclusion The therapy of acupuncture combining with biofeedback is benefit to improve the sleep quality of senile chronic insomnia patients,meanwhile the anxiety and depression associated with insomnia can be improved.
