AIM:To identify and quantify the expression of IL-1βand IL-17 in mast cells ( MCs) in different types of human pericapical diseases using double immunofluorescence staining .METHODS: The specimens ( n=102 ) , including healthy control ( n=35 ) , periapical cyst ( n=35 ) and periapical granuloma ( n=32 ) , were involved in the present study .The tissue samples were fixed in 10% buffered formalin for at least 48 h and then embedded in paraffin . Serial 5-μm-thick sections were deposited onto SuperFrost/Plus microscope glasses .Routine staining of the sections using hematoxylin&eosin ( HE) was performed for morphological evaluation .The number of IL-1βand IL-17 positive MCs was identified by double immunofluorescence staining .RESULTS:Compared with the healthy controls , the inflammation score of periapical lesions was significantly increased in the periapical patients (P<0.01).The density of IL-1βand IL-17 posi-tive MCs in the periapical lesions were obviously higher than that in the healthy controls (P<0.01).However, no signifi-cant difference between periapical cyst and periapical granuloma was observed .The Pearson correlation analysis showed that there was a positive correlation between the density of IL-1βand IL-17 double positive MCs and inflammation score in dif-ferent groups of specimens (P<0.01).CONCLUSION:There is significantly increased number of MCs , along with in-creased density of IL-1βand IL-17 positive MCs in human periapical lesions .The increased density of IL-1βand IL-17 positive MCs has the similar tendency as the severity of tissue inflammation in human periapical lesions , suggesting that IL-1βand IL-17 positive MCs may play an important role in the pathogenesis of human periapical diseases .

Objective To investigate modulatory effects of Neb-SNP on inflammatory response and to explore the protection mechanisms of Neb-SNP in newborn piglets with ARDS. Methods Forty-five neonatal swines were randomly divided into five groups:group A (controlled group ,n = 9), group B (physiological saline group,n =9),group C (Neb-SNP 1 mg/ml,0. 9% NaCl, n = 9), group D (Neb-SNP 5 mg/ml,0. 9% NaCl, n = 9) and group E (Neb-SNP 10 mg/ml,0. 9% NaCl, n = 9). The pathological changes and activity of NF-κB in the lung tissue ,TNF-α ,IL-10 and IL-12 concentrations in serum at 30 minutes,60 minutes and 120 minutes after aerosol inhalation were observed. Results Activity of NF-κB and serum concentrations of TNF-α and IL-12 in the Neb-SNP treated group were lower than group B(P ＜0. 05) ,and serum IL-l0 concentration was obviously higher in the Neb-SNP group(P ＜0. 05). With an increase of Neb-SNP concentration,activity of NF-κB and serum concentrations of TNF-α and IL-12 were obviously increased, while serum concentrations of IL-10 was increased in group D and group E than that of group C (P ＜ 0. 05).Conclusion Inhalation of Neb-SNP reduced lung injury induced ARDS through lowering NF-κB activity and inhibiting expression of harmful inflammatory cytokines.

Objective: To analyze the efficiency characteristics and trend of tertiary general public hospitals from both static and dynamic perspectives. Methods: After collecting data of personnel, equipment, assets, health services and other inputs-output indicators from 50 tertiary public hospitals from 2006 to 2012 , this paper uses C2 R-DEA and BC2-DEA models, as well as Malmquist Index model to build suitable analysis model. Results:About 10%~12% of the sample hospitals are in a relatively effective operational state, and the mean values of allocation effi-ciency and scale efficiency are 0. 956 and 0. 943, respectively, which are close to the efficient frontier. The mean values of pure technical efficiency, technical efficiency, cost efficiency and overall efficiency are 0. 796, 0. 784, 0. 714 and 0. 714, respectively, which are relatively poor compared with the efficiency frontier. Moreover, the number of hospitals that are in the state of diminishing returns to scale increased from 7 . 69% to 26 . 31%, while the number of hospitals that are in the state of increasing returns to scale decreased from 80. 77% to 58. 34%. The changes in techno-logical progress, Malmquist productivity index, technical efficiency index, pure technical efficiency index and scale effi-ciency index remained a relatively stable consistency, and showed continuous improvement and steady development trend. Conclusion:Tertiary general public hospitals are facing the transformation of driving force for development and incentive mechanisms. This needs not only to change the management concept and development mode of the hospitals, but also to build evaluation standards of optimum efficiency that are relevant to the structure, process and outcome, in order to pro-mote the transformation of hospital governance and development model that includes the functions of government.

Objective To analyze the main practices of capitation payment system reform in the case areas and put forward enlightenments and suggestions in this regard. Methods The implementation practices of the case areas were summarized, and descriptive statistical analysis was carried out on the implementation effects. Results By analyzing the effectiveness of the case areas′reform, it was found that the case areas are curbing the excessive growth of medical expenses (for example, outpatient fees per visit of Dingyuan county-level hospitals decreased from 245.11 yuan in 2015 to 218.40 yuan in 2017), increasing the actual compensation ratio of residents ( for example, the actual compensation ratio of Funan increased from 59.80% in 2015 to 63.28% in 2017), forming a medical treatment pattern within the county (for example, out-of-county compensation ratio in Dingyuan decreased from 37.38% in 2015 to 31.13% in 2017), achieving double-way referrals (for example, the number of referrals to superior hospitals of Jimo increased from 98 in 2015 to 328 in 2017), improving the subsidence of quality services, and controlling the risks of medical insurance funds. Conclusions At present, the reform of the case areas has been implemented steadily and achieved results. It is recommended to further improve such aspects as reform coordination, insurance standard setting, incentive mechanism establishment, and leadership to ensure the reform progress.

Pilot areas have achieved initial success in capitation reform. On the other hand, challenges remain unsolved in terms of practical pathways, change of national medical insurance management system, related measures, incentives and allocative mechanism for implement of the reform. With the concerning on progress, practice, effects and challenges of typical areas, this article established an institutional framework. On such basis, we propose to design and refine a scheme in terms of 5 aspects, namely strengthening the basic medical care packages′financing, setting contents and standard of the basic medical care packages rationally, establishing effective evaluation system and formulating supporting measures.
