Objective To explore the sleep quality and its influencing factors among the patients with schizophrenia of Hui and Han populations in the rural areas in Ningxia Hui Autonomous Region.MethodsTotally 296 patients with schizophrenia of Hui and Han populations in the rural areas were selected from 2 counties of Wuzhong and Zhongwei in Ningxia Hui Autonomous Region by using cluster random sampling method.Self-made general information questionnaire was used to collect the demographic and clinical characteristics of the patients with schizophrenia.The Pittsburgh Sleep Quality Index(PSQI) was used to evaluate the sleep quality.Brief Psychiatric Rating Scale(BPRS),Hamilton Depression Scale(HAMD) and Hamilton Anxiety Scale(HAMA) were used to measure the psychotic symptoms,depressive symptoms and anxiety symptoms,respectively.ResultsIn the rural areas,the incidence of sleep disorder in the patients with schizophrenia of Hui and Han populations was 84.5%.The influencing factors of sleep disorder in the patients with schizophrenia in the rural areas were age(B=0.055,P=0.012,OR=1.057,95%CI:1.012-1.103),nationality(B=2.250,P<0.01,OR=9.485,95%CI:2.701-33.319),marital status(B=-1.506,P=0.003,OR=0.222,95%CI:0.081-0.605),course of disease(B=-0.003,P=0.089,OR=0.997,95%CI:0.993-1.001),the total score of HAMD(B=0.079,P=0.007,OR=1.083,95%CI:1.021-1.148)and the total score of HAMA(B=0.060,P=0.036,OR=1.061,95%CI:1.004-1.122).ConclusionSleep disorders are common and associated with multiple factors in patients with schizophrenia of Hui and Han populations in Ningxia rural area.In clinical practice,more attention should be paid to the identification and intervention of sleep disorders,so as to improve the sleep quality for the patients with schizophrenia.

OBJECTIVE To investigate the distribution and the resistance of pathogens from the children with VAP in PICU,and to analyze the reasons of antibiotics resistance of the pathogens.METHODS The sputum obtained from the children with final diagnosis of VAP in PICU was cultured and identified from Jan 2005 to Dec 2006.The resistance of the bacteria identified to antibiotics used frequently was determined by Kirby-Bauer method.RESULTS A total of 187 strains were isolated from sputum specimens,of which Gram-negative bacilli and Gram-positive cocci accounted for 76.5% and 23.5%,respectively.Acinetobacter baumannii(17.7%),Escherichia coli(16.0%),Pseudomonas aeruginosa(15.0%) and Klebsiella pneumoniae(13.9%) were the most frequently isolates of Gram-negative bacilli.Their resistant rates to ?-lactam antibiotics were high,especially the ESBLs-producing strains in E.coli and K.pneumoniae.The Staphylococcus epidermidis(5.9%),Staphylococcus aureus(4.8%) and Enterococcus faecalis(4.3%) were the most common strains of Gram-positive cocci.No vancomycin-resistanct strains were found,but resistance rates to ?-lactam antibiotics and other antibiotics were high in S.epidermidis and S.aureus.CONCLUSIONS The main strains cultured from the sputum specimens of children with VAP in PICU are Gram-negative bacilli with high resistance rates to antibiotics,especially the ESBLs producing bacilli to ?-lactam antibiotics.Staphylococcus are the main Gram-positive cocci.

[Summary] A total of 128 individuals with type 2 diabetes underwent continuous glucose monitoring for 3 consecutive days.The dawn phenomenon was defined by three different parameters according to the previous research:(1)the absolute increase of glucose level from nocturnal nadir to prebreakfast value(?G) above 20 mg/dl;(2)?G above 10 mg/dl;( 3 ) insulin requirement increased at least 20%.The participants were secondarily separated by presence/absence of a dawn phenomenon based on the definitions above.The impact on blood glucose fluctuation of different groups was assessed according to the standard deviation of blood glucose( SDBG) , the area under curve above 10 mmol/L ( AUC ) , and the mean amplitude of glycemic excursions ( MAGE ) , etc.The frequencies of dawn phenomenon were 64.8%(?G≥20mg/dl), 85.2%(?G≥10 mg/dl), and 59.4%(rise in insulin requirement≥20%)respectively.The impacts on SDBG, AUC, MAGE, and MODD were without statistical difference(P>0.05) between the presence and absence of the dawn phenomenon patients when?G≥10 mg/dl.However, the differences reached statistical significance(P<0.05) when ?G≥20 mg/dl and the increase in insulin requirement≥20%. Besides, the incidence of dawn phenomenon was positively correlated with HOMA-IR, HbA1C , and free C-peptide.Dawn phenomenon is a very frequent event in type 2 diabetes and not only impacts the overall glycemic control but also exaggerates glucose fluctuation.To be clinically relevant, ?G≥20mg/dl should be taken as the quantitative criterion of the dawn phenomenon.

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.

OBJECTIVES: Chlorogenic acid has various physiological activities such as antibacterial, anti-inflammatory, and antiviral activities. Studies have shown that chlorogenic acid can alleviate the inflammatory response of mice with acute lung injury (ALI), but the specific mechanism is still unclear. This study aims to investigate whether chlorogenic acid attenuates lipopolysaccharide (LPS)-induced ALI in mice by regulating the microRNA-223 (miR-223)/nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) axis. METHODS: SPF grade BALBc male mice were randomly divided into a control group, a model group, a chlorogenic acid group, a chlorogenic acid+miR-223 negative control (miR-223 NC) group, and a chlorogenic acid+miR-223 inhibitor (miR-223 antagomir) group, 10 mice in each group. Except the control group, the other groups were instilled with 4 mg/kg LPS through the airway to establish the ALI mouse model. After the modeling, the mice in the chlorogenic acid group were continuously given chlorogenic acid (100 mg/kg) by gavage for 7 d. The chlorogenic acid+miR-223 NC group and the chlorogenic acid+miR-223 antagomir group were given 100 mg/kg chlorogenic acid by gavage every day, and then were injected with 10 μL of miR-223 NC (0.5 nmol/μL) and miR-223 antagomir (0.5 nmol/μL) respectively for 7 consecutive days.The control group and the model group were replaced with normal saline. The lung tissues of mice were taken to measure the ratios of lung wet to dry weight (W/D). The bronchoalveolar lavage fluid of mice was collected to measure the levels of TNF-α, IL-6, and IL-1β by ELISA kit and to count the number of eosinophils (EOS), lymphocytes, neutrophils under light microscope. After HE staining, the pathological changes of lung tissues were observed and lung injury was scored. qRT-PCR method were used to determine the expression levels of miR-223 in lung tissues. Western blotting was used to determine the expression levels of NLRP3 protein in mouse lung tissues. Luciferase reporter assay was used to analyze the targeting relationship of miR-223 to NLRP3. RESULTS: Compared with the control group, the lung W/D value, the lung injury score and the level of inflammatory factors in the bronchoalveolar lavage fluid were significantly increased in the model group (all P<0.05); the infiltration of inflammatory cells in the lung tissue was severe; the alveolar space was significantly increased; the alveolar wall was significantly thickened; the number of EOS, lymphocytes, and neutrophils in the bronchoalveolar lavage fluid was significantly increased (all P<0.05); the expression levels of miR-223 in lung tissue were significantly decreased (P<0.05); and the protein expression levels of NLRP3 were significantly increased (P<0.05). Compared with the model group, the W/D value of lungs, lung injury score, and levels of inflammatory factors in bronchoalveolar lavage fluid were significantly decreased in the chlorogenic acid group, the chlorogenic acid+miR-223 NC group, and the chlorogenic acid+miR-223 antagomir group (all P<0.05); lung tissues damage was alleviated; the numbers of EOS, lymphocytes, and neutrophils in bronchoalveolar lavage fluid were significantly decreased (all P<0.05); the expression levels of miR-223 in lung tissues were significantly increased (P<0.05); and the expression levels of NLRP3 protein were significantly decreased (P<0.05). Compared with the chlorogenic acid group, the lung W/D value, lung injury score, and inflammatory factor levels in the bronchoalveolar lavage fluid were significantly increased in the chlorogenic acid+miR-223 antagomir group (all P<0.05); lung tissue damage was aggravated; the number of EOS, lymphocytes and neutrophils in bronchoalveolar lavage fluid significantly increased (all P<0.05); the expression levels of miR-223 in lung tissues were significantly decreased (P<0.05); and the expression levels of NLRP3 protein were significantly increased (P<0.05). The results of luciferase reporter assay showed that miR-223 had a targeting relationship with NLRP3. CONCLUSIONS Chlorogenic acid may increase the level of miR-223, target the inhibition of NLRP3 expression, reduce LPS-induced inflammatory response in ALI mice, and alleviate pathological damage of lung tissues.
