Objective:To explore the propagable experience and methods of controlling the rate of cesarean sec-tion through the summary of the innovative measures in four counties. Methods:The cases of natural birth and cesare-an section from 2009 to 2013 in four counties were analyzed respectively. The interventions of controlling cesarean section rate have been summarized. Results:The average cesarean section rate of four counties in five years is on the decline, since 2009 the rate were 60. 2%,62. 3%,59. 3%,51. 4%,48. 1%. Conclusions: The interventions really worked, but did not do the best. Improving the social attention on these innovative measures, strengthening surveil-lance mechanism, regulating the medical behaviors of delivery hospitals, enhancing the midwifery training and promo-ting the interventions under the coordination of local government can further reduce the rate of cesarean section.

Objective To study the outcomes and problems of comprehensive medical pricing reform in Jiangsu.Methods The business operations,drug proportion and patient′s expenses of 28 pilot hospitals in 1 5 counties of the province before and after the reform were compared,to learn the impacts of the pricing reform on both hospitals and patients.Results Medical revenue and medical service quantity of these hospitals during this period(January to June)of 2012—2014 maintain a fast growth,with lower drug proportions,and patients′expenditure unchanged.Compared with data of the same period in 2012, the total revenue growth rates of the hospitals in 2013 and 2014 were 13.4% and 1 1.1% respectively;and their drug proportions were 44.9% and 42.3%;and the expenditure growth rates for outpatient/emergency service were 5.9% and 3.1% respectively.Conclusions The reform has achieved an initial success.However the pricing system,needs to be further rationalized to build a better price formation mechanism,in line with relevant reforms.

This study was aimed to optimize the extraction process of hyperoside from leaves ofAcanthopanax senticosusby compounding-enzyme method and orthogonal experiment. The hyperoside compound was regarded as standard and determined by HPLC. Based on the experiments of 4 factors including the enzyme amount, temperature, extraction time and PH values, the extraction process of hyperoside was determined by the orthogonal experiments and variance analysis. The results of single-factor experiments showed that different enzymes showed different effects on the enhance yield of hyperoside. The effects of different factors showed that the order of PH, neutral protease, temperature, time, pectinase, xylanase and cellulose was from strong to weak. Through orthogonal analysis, the optimum conditions were 2% pectinase, 2% xylanase, 0.5% neutral protease, and 0.5% cellulose, under the temperature of 30°C, extraction time of 10 min, and pH = 4.5. Under these conditions, the extraction rate was 1.84%. The yield was increased 107% compared with traditional process. It was concluded that the use of compounding enzyme can increase the yield of hyperoside, which possessed a lot of economic benefits.

Objective: To explore the effects of different concentrations of glucose solution on the survival of Aedes albopictus and Culex pipiens pallens larvae, the attraction to mosquitoes and egg-laying behaviors, so as to provide the reference for developing mosquito control technology based on sugar bait. Methods: White porcelain bowls were filled with 100 mL of 3%, 5%, 8%, 10% and 15% glucose solutions. Ten of fourth instar larvae of Aedes albopictus or Culex pipiens pallens were added to each bowl, and the survival of larvae was recorded after 2, 4, 6, 24, 48 and 72 hours. Egg-laying cups containing 5%, 8% and 15% glucose solution were put in mosquito cages containing fully blooded female mosquitoes of Aedes albopictus and Culex pipiens pallens (50 mosquitoes each), and the total number of eggs laid in 72 hours was observed. The analogous site room was filled with fully blooded and starved female mosquitoes of Aedes albopictus and Culex pipiens pallens (100 mosquitoes each), and simple mosquito control buckets containing 5% and 8% glucose solution and black sticky insect plates. The number of mosquitoes and eggs was observed after 6 days. All the above experiments were repeated 3 times using dechlorinated water as the control. Results: The 72 hour corrected mortality rates of Aedes albopictus and Culex pipiens pallens larvae gradually increased with the increase of glucose concentration. The glucose solution with 5% and higher concentrations was not suitable for mosquito larvae to survive. The attraction of egg-laying behaviors to Aedes albopictus and Culex pipiens pallens gradually decreased with the increase of glucose concentration. The effects were similar between 5% and 8% glucose solution, with the averages of 686.67 and 682.33 eggs for Aedes albopictus, and 3.00 and 2.33 egg rafts for Culex pipiens pallens. In analogous site room, there were 93.33, 105.00 and 130.33 adult mosquitoes captured on average in the control group, 5% and 8% glucose solution groups, respectively, with 8% glucose solution group more attractive to adult mosquitoes than the control group (F=3.283, P=0.030); there were 70.33, 55.33 and 63.00 Aedes albopictus eggs (eggs counts+larvae counts) on average, respectively, with statistically significant differences among the three groups (H=6.761, P=0.034). Conclusion Glucose solution with concentration of 5% or higher can effectively inhibit the survival of Aedes albopictus and Culex pipiens pallens larvae, and attractive to adult mosquitoes and egg-laying behavoirs.

Thoracic ossification of ligament flavum (TOLF) is a pathological process of heterotopic bone formation from ligamentum flavum tissue, which is the most common cause of thoracic spinal stenosis and thoracic myelopathy. Imaging examination is the predominant measure for localization and qualitative diagnosis for TOLF. Various TOLF classification systems have been reported currently, based on its morphology, distribution, configuration of compressed spinal cord or its association with peripheral tissue structures. However, there has been no unified classification due to confusing clinical applications. Therefore, we conducted a review to summarize TOLF classification systems and to evaluate the reliability of these classification systems and the diagnostic accuracy of various imaging modalities. As demonstrated in literatures, the diagnostic accuracy of radiography and the reliability of related classification were low. CT-based Sato classification (lateral, extended, enlarged, fused, tuberous) and Kuh classification (unilateral, bilateral, bridging), MRI-based Kuh classification (round, beak) and Chen Zhongqiang classification (isolated, skipping, continuous), Muthukumar classification combined with dural ossification (Tram track sign, Comma sign) elaborated ossification characteristics from different angles and dimensions. These classification systems were clinically significant in pathogenesis implication, risk assessment, treatment guidance and prognosis judgement, which showed high diagnostic accuracy and reliability. Combining multi-dimension and multi-level parameters of CT and MRI will play an important role in the diagnosis, treatment and new classification research of TOLF.
