Objective To establish and verify the personalized reference interval of blood cells.Methods The results of blood cells from 2 089 health subjects in 2014,2015 and 2016 were collected.The ratio of the later results to the previous results was defined as the fluctuation (λ).The ratio (λ1) of the results of 2015 to the results of 2014 was calculated and λ1 was analyzed statistically to establish the fluctuation reference interval (CIλ).The ratio (λ2) of the results of 2016 to the results of 2015 was calculated.λ2 was used to verify λ2.The personalized reference interval (CIp) was established by multiplying each result of 2015 and CIλ.CIp was verified by results of 2016.The ratio of the upper and lower limits of CIp was calculated.The ratio of the upper and lower limits of the reference interval (WS/T 405) was calculated.Results The values of CIλ were as follows:WBC (0.66 to 1.53),L(0.67 to 1.51),M (0.50 to 2.00),N(0.56 to 1.78),E(0.4 to 2.51),PLT(0.76 to 1.32),RBC(0.92 to 1.12),Hb(0.92 to 1.11),Hct(0.91 to 1.12),MCV(0.95 to 1.07),MCH(0.95 to 1.05)and MCHC(0.94 to 1.06).The validation tests of CIλ and CIp showed that both CIλ and CIp were suitable for this laboratory.Compared with the reference interval of professional criteria,the ratio of the upper and lower limits of the CIp was smaller than that of traditional criteria.Conclusion CIp for this laboratory was established and verified.Compared with traditional criteria,CIp should be more personalized and highly sensitive.

Objective:To analyze the implementation and effectiveness of primary health care reform in Feixi county, Anhui province. Methods: This paper uses data analysis of interviews with key insiders, policy documents and archives, as well as institutional questionnaire survey and other methods to collect information, and then it com-bines qualitative and quantitative research to arrive at research findings through cross-analysis and interpretation. Re-sults:From 2010 to 2014, the reform enhanced the capacity of primary health care in four main aspects, including capacity building of primary health care personnel, network construction of primary health care system, improvement of working conditions, and system construction of institutional management. Accordingly, the human capacity of pri-mary health care personnel was improved, their enthusiasm for work increased, their income was raised, the working conditions were improved, the cooperation mechanism for vertical and horizontal health care services was established, and the consultation rate and primary health care utilization in Feixi county increased. Conclusion:Both the“bottom-up” exploration approach and “from point to area” implementation strategy adopted by Feixi county have not only been the core content of primary health care system’s comprehensive reform, but also effectively leveraged the other aspects of the reform. They have played an important role in deepening medical reform and establishing institutional mechanism of health care system.

Objective:To analyze reverse effects induced in the implementation process of“primary health care strengthening” policies, and the innovative initiatives and countermeasures raised in primary health care system’s comprehensive reform of Feixi county. Method:Based on the principles of Critical Discourse Analysis ( CDA) , this paper designs its analytical framework for policy analysis. Results:Many reverse effects appeared in the implementa-tion process of “primary health care strengthening” policies. However, through improvements in terms of manpower upgrading, network building, working conditions and management mechanisms, Feixi county has successfully strengthened the capacity building for primary health care institutions. Conclusions:The expected and unexpected re-sults should be evaluated systematically when the policies are being implemented, and local governments need to pro-ceed according to local conditions in order to prevent unintended reverse effects from happening.

The fragmentation of health care system within a county and serious capacity constraints of health-care services in township health centers are generally the most significant problems facing underdeveloped counties in western China. Under constraints of limited public financial resources, how to increase service capability of township health centers and improve service quality, continuity and convenience of health care system has become one of the most severe challenges in implementing China’s county health care system reform. This paper takes Huangzhong coun-ty, Qinghai province as a case study. It investigates how the locals use health care alliance to vertically integrate county health care resources during reform implementation, analyzes various aspects of reform measures and the corre-sponding structural characteristics such as the integration of administrative management, integration of human re-sources, dual diagnosis referral, interoperability of information systems, sharing of resources and test results, etc. , and provides similar China’s counties with a case study to be used for reference.

Objective:After examining the changes in medical expenses and flows of hospitalized patients with-in and outside the county under the New Rural Cooperative Medical Scheme ( NRCMS ) before and after the imple-mentation of health care alliance reform, this paper analyzes the impacts of health care alliance reform on the visiting rate of NRCMS patients within the county and explores their causes and channels. Methods:This paper uses the hos-pitalization data of NRCMS patients in 2013 and 2014 collected from Huangzhong county Qinghai province and inter-views with key informants and analyzes the hospitalization expenses, visiting flows and other indicators of patients. Results:After starting health care alliance reform, the total number of hospitalized patients to seek treatment outside the county decreased by 6 . 38%, the total hospitalization expenses to seek treatment outside the county decreased by 22 . 13%, and the hospitalization expenses per inpatient day to seek treatment within and outside the county increased by 14. 41% and 20. 69% respectively. Conclusions: By improving service capabilities of township health centers and increasing synergies between county-township-village health institutions, the county health care alliance reform has suc-cessfully enhanced the service capabilities of health care systems in the whole county and reasonably helped patients with common diseases to be hospitalized outside the county and frequently hospitalized people to return back to the county.

Objective: To investigate the effects of activating silent information regulator 1 (SIRT1) on the early kidney damage in rats with severe burn. Methods: Thirty healthy male SD rats were divided into sham injury group (SI), pure burn group (PB), and SIRT1 activator group (SA) according to the random number table, with 10 rats in each group. Rats in groups PB and SA were inflicted with 30% total body surface area full-thickness scald (hereinafter referred to as burn) on the back. Immediately after injury, rats in group PB were intraperitoneally injected with normal saline in the dosage of 50 mL/kg, and those in group SA with 1 mg/mL (final mass concentration) resveratrol in the dosage of 50 mL/kg. Rats in group SI were sham injured and intraperitoneally injected with normal saline in the dosage of 50 mL/kg immediately after injury. Kidney tissue and abdominal aorta blood of rats in the three groups were collected at 24 hours after injury. The morphology of kidney tissue was observed after HE staining. The serum content of creatinine and urea nitrogen was determined with enzyme-linked immunosorbent assay. Protein expressions of SIRT1, Bax, and Bcl-2 in kidney tissue were determined with Western blotting. mRNA expressions of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and IL-10 in kidney tissue were determined with real-time fluorescent quantitative reverse transcription polymerase chain reaction. Data were processed with one-way analysis of variance and LSD-t test. Results: (1) In rats of group SI, structures of kidney tubules and glomeruli were intact. In rats of group PB, structures of kidney tubules were not clear with casts in them, and glomeruli showed pyknosis. In rats of group SA, structures of kidney tubules were relatively intact, and the pyknosis of glomeruli were slighter as compared with that of group PB with fewer glomeruli showing pyknosis. (2) The serum content of creatinine and urea nitrogen in rats of group PB was (67±14) μmol/L and (22.0±4.4) mmol/L, respectively, which was significantly higher than that of group SI [(28±7) μmol/L and (5.5±1.2) mmol/L respectively, with t values respectively 6.07 and 11.53, P values below 0.01]. The serum content of creatinine and urea nitrogen in rats of group SA was (39±9) μmol/L and (14.1±1.7) mmol/L, respectively, significantly lower than that of group PB (with t values respectively 4.09 and 4.17, P values below 0.01). (3) Compared with those of group SI, protein expressions of SIRT1 and Bcl-2 in kidney tissue of rats in group PB were significantly decreased (with t values respectively 16.32 and 19.58, P values below 0.01), while the protein expression of Bax was significantly increased (t=5.98, P<0.01). Compared with those of group PB, protein expressions of SIRT1 and Bcl-2 in kidney tissue of rats in group SA were significantly increased (with t values respectively 6.94 and 5.37, P values below 0.01), while the protein expression of Bax was significantly decreased (t=3.44, P<0.01). (4) mRNA expressions of TNF-α, IL-1β, and IL-10 in kidney tissue of rats in group PB were 17.0±4.0, 2.27±0.59, and 2.5±0.9, respectively, significantly higher than those of group SI (1.0, 1.00, and 1.0, respectively, with t values from 3.27 to 8.93, P<0.05 or P<0.01). mRNA expressions of TNF-α and IL-1β in kidney tissue of rats in group SA were 6.8±1.2 and 1.18±0.26, respectively, significantly lower than those of group PB (with t values respectively 4.59 and 4.32, P values below 0.01). mRNA expression of IL-10 in kidney tissue of rats in group SA was 5.0±1.0, significantly higher than that of group PB (t=5.51, P<0.01). Conclusions Activating SIRT1 on early stage of severe burn in rats can decrease levels of creatinine and urea nitrogen, thus improving the kidney function. It can down-regulate the protein expression of Bax and up-regulate the protein expression of Bcl-2, thus reducing the apoptosis in kidney tissue. Meanwhile, it can inhibit expressions of TNF-α and IL-1β and promote the expression of IL-10, thus alleviating the inflammatory response in kidney.

Objective: To explore the effects of microRNA-34a on regulating silent information regulator 1 (SIRT1) and influence of SIRT1 on myocardial damage of rats with severe burns at early stage. Methods: (1) Twenty-four Sprague-Dawley (SD) rats were divided into sham injury (SI) group, simple burns (SB) group and SIRT1 agonist (SA) group according to the random number table (the same grouping method below), with 8 rats in each group. Rats in groups SB and SA were inflicted with 30% total body surface area full-thickness scald (hereinafter referred to as burns) on the back, and rats in group SI were sham injuried on the back. Immediately after injury, rats in groups SI and SB were intraperitoneally injected with normal saline of 50 mL/kg, and rats in group SA were intraperitoneally injected with normal saline of 50 mL/kg and 1 mg/mL resveratrol of 50 mg/kg. At 6 h post injury, abdominal aortic blood was collected to make serum and myocardial tissue of rats was collected. (2) Myocardial cells of twelve neonatal SD rats were collected and divided into microRNA-34a mimic control (MMC) group, microRNA-34a mimic (MM) group, microRNA-34a inhibitor control (MIC) group, and microRNA-34a inhibitor (MI) group, which were respectively transfected with gene sequences of mimic control, mimic, inhibitor control, and inhibitor of microRNA-34a. The microRNA-34a expression level and protein expression level of SIRT1 in myocardial cells were respectively detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blotting. Another batch of myocardial cells were divided into microRNA-34a inhibitor control+ burn serum (MCB) group, microRNA-34a inhibitor+ burn serum (MB) group, and microRNA-34a inhibitor+ burn serum + EX527 (MBE) group. Myocardial cells in group MCB were transfected with gene sequence of inhibitor control, and myocardial cells in the later groups were transfected with gene sequence of inhibitor of microRNA-34a. After transfection of 48 h, myocardial cells in group MBE were cultured in Dulbecco′s modified Eagle′s medium (DMEM) solution for 6 hours, with serum in group SB of volume fraction of 10% and final amount-of-substance concentration of 1 mol/L, and myocardial cells in the other 2 groups were cultured in DMEM solution with serum from rats of group SB of volume fraction of 10%. The protein expression levels of myocardial cells of SIRT1, cleaved-caspase-3, and Bax were detected by Western blotting. (3) Myocardial tissue from (1) was collected to detect expression levels of microRNA-34a and mRNA of SIRT1 in groups SI and SB by real-time fluorescence quantitative RT-PCR. Morphology of myocardial tissue of rats in groups SI, SB, and SA was observed with biological image navigator. The mRNA expression levels of interleukin 1β (IL-1β) and tumor necrosis factor (TNF-α) of rats in groups SI, SB, and SA were detected by real-time fluorescence quantitative RT-PCR. The expression levels of cleaved-caspase-3, and Bax of myocardial tissue of rats in groups SI, SB, and SA were detected by Western blotting. Data were processed with one-way analysis of variance and least-significant difference test. Results: (1) After transfection of 48 h, the expression level of microRNA-34a of myocardial cells in group MM was 4.67±0.92, significantly higher than 1.03±0.04 in group MMC (P<0.01); the protein expression level of SIRT1 of myocardial cells in group MM was 0.35±0.06, significantly lower than 1.12±0.11 in group MMC (P<0.01). After transfection of 48 h, the expression level of microRNA-34a of myocardial cells in group MI was 0.26±0.07, significantly lower than 1.33±0.07 in group MIC (P<0.01); the protein expression level of SIRT1 of myocardial cells in group MIC was 1.12±0.16, significantly lower than 1.74±0.34 in group MI (P<0.01). At 6 h after culture, compared with those in group MCB, the SIRT1 protein expression level of myocardial cells in group MB was significantly increased (P<0.05), while cleaved-caspase-3 and Bax protein expression levels of myocardial cells in group MB were significantly decreased (P<0.05). Compared with those in group MB, the SIRT1 protein expression level of myocardial cells in group MBE was with no significantly statistical difference (P>0.05), and cleaved-caspase-3 and Bax protein expression levels were significantly increased (P<0.05). (2) At 6 h post injury, compared with that in group SI, the microRNA-34a expression level of myocardial tissue in group SB was significantly increased (P<0.01), and the mRNA expression level of SIRT1 of myocardial tissue in group SB was significantly decreased (P<0.01). At 6 h post injury, myocardial cells in group SI arranged neatly with normal nucleus and no inflammatory cells infiltration; myocardial cells in group SB arranged disorderly, with no abnormal nucleus, and obvious inflammatory cells infiltration; myocardial cells in group SA arranged neatly, with normal nucleus and little inflammatory cells infiltration. At 6 h post injury, compared with those in group SB, the mRNA expression levels of IL-1β and TNF-α, and the protein expression levels of cleaved-caspase-3 and Bax of myocardial tissue in groups SI and SA were significantly decreased (P<0.01). Conclusions The microRNA-34a expression level of myocardial tissue of rats with severe burns at early stage increases, which decreases the expression level of SIRT1, and increases the expression levels of IL-1β, TNF-α, cleaved-caspase-3 and Bax, leading to obvious myocardial damage. Activation of SIRT1 can alleviate myocardial damage of rats with severe burns at early stage through decreasing expression levels of IL-1β, TNF-α, cleaved-caspase-3, and Bax.
