In this cross-sectional study, consecutive Chinese Han ethnic inpatients in the Division of Cardiology, the First Affiliated Hospital of Soochow University from January 1, 2010 to December 31, 2013 were included. According to the exclusion criteria, 9 587 patients [1 604 with type 2 diabetes mellitus (T2DM) and 7 983 without T2DM]were obtained for final analysis. Logistic regression model was used to analyze the association of ApoB/A-1 ratio with T2DM and the possible interactions between ApoB/A-1 ratio and other risk factors. The results showed that the distribution of ApoB/A-1 ratio was positively skewed in Chinese Han ethic population. The median of ApoB/A-1 ratio of female was lower than that of male (0.68 vs 0.73,P<0.01). In all groups, the proportion of T2DM was increased with the raised ApoB/A-1 ratio. By the stratification analyses of sex, age, coronary artery disease, and the use of statins, ApoB/A-1 ratio was still correlated with T2DM. There existed significant interactions between ApoB/A-1 ratio and the smoking status or creatinine in T2DM.

Objective:To explore the protective effect of emodin on D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced acute liver injury and its mechanism.Methods:A total of 40 male BALB/c mice were randomly (random number) divided into 5 groups ( n=8 in each group): the control group, the emodin group, the D-GalN/LPS group, the emodin+D-GalN/LPS group and the 3-MA+emodin+D-GalN/LPS group. D-GalN (700 mg/kg) and LPS (10 μg/kg) were intraperitoneally injected to induce acute liver injury in mice. Autophagy inhibitor 3-MA (15 mg/kg) and/or emodin (20 mg/kg) were intraperitoneally injected 30 min before the liver injury model. The animals were sacrificed under anaesthesia 6 h after D-GalN/LPS challenge, blood samples and liver tissues were collected. The levels of alanineaminotransferase (ALT) and aspartateaminotransferase (AST) in serum, and myeloperoxidase (MPO) activity of liver tissues were determined by colorimetric quantitative method; the levels of tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured by ELISA; the expression of LC3-II and Beclin 1 in the liver tissues were evaluated by Western blot; the pathological changes of liver was evaluated by HE staining. Animal survival rate was also analyzed. The one-way ANOVA was use to compare quantitative data, SNK- q test was used for pairwise comparison between two groups, and Games-Howell test was used when homogeneity of variance were not met. Results:Compared with the control group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(2 476.80 ± 263.14) U/L, (271.71 ± 47.15) U/L, (537.92 ± 89.35) pg/mL, (169.74 ± 25.52) pg/mL, and (1.37 ± 0.22) U/mg] were obviously increased in the D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the levels of ALT, AST, TNF-α, IL-6 and MPO activity [(1 248.01 ± 380.70) U/L, (142.59 ± 34.63) U/L, (288.91 ± 67.21) pg/mL, (61.83 ± 13.64) pg/mL, and (0.80 ± 0.21) U/mg] were obviously decreased in the emodin+ D-GalN/LPS group ( P<0.05). Compared with the D-GalN/LPS group, the histopathological abnormalities in liver tissue were significantly alleviated and the survival rate of mice was improved in the emodin+ D-GalN/LPS group. Compared with the control group, the expression of LC3-II and Beclin1 was decreased in the liver tissue in the D-GalN/LPS group, while compared with the D-GalN/LPS group, the expression of LC3-II and Beclin1 was increased in the emodin+ D-GalN/LPS group. With co-administration of 3-MA, the protective effects of emodin in acute liver injury were reversed, the levels of AST, ALT, TNF-α, IL-6, and MPO [(2 398.78 ± 233.57) U/L, (242.79 ± 43.46) U/L, (505.07 ± 67.89) pg/mL, (151.46 ± 14.11) pg/mL, and (1.27 ± 0.15) U/mg] were increased, and the pathological damage of liver tissue was aggravated. Conclusions:Emodin alleviates D-GalN/LPS-induced acute liver injury in mice, which may be related to the activation of protein LC3-II, Beclin1 and restored autophagy.

Sall4, a member of sall4 gene family, plays important roles in embryo development; organogenesis as well as pluripotency maintenance and re-establishment. There are two isoforms of Sall4, Sall4A and Sall4B. The sequence of porcine sall4 gene is still not reported. Because of its distinct role in maintaining the pluripotent state of stem cells, we cloned and sequenced porcine sall4 gene and assessed its expression in pig tissues and embryos. One 2 372 bp nucleotide sequence representing the full-length cDNA of pig sall4 was obtained by 5'and 3'RACE. Analyses of putative protein sequence showed a 70% to 80% identity with isoform Sall4B of human and mouse. Comparing with Sall4A, the identity reduced to 30% to 55% because of the loss of a zinc-finger domain-rich fragment. Assessment of sall4b expression in porcine tissues by Real-time PCR showed that it expressed most strongly in ovary and stronger in spleen, lung, heart and testis. For preimplantation embryos, the expression level was lower in 4-cell embryos compared with other stages. Immuno-fluorescence analysis of Sall4 on porcine preimplantation embryos indicated that it expressed in all the preimplantation embryos and located in nucleus, in blastocyst it preferentially limited in ICM cells. Expression pattern in early embryos suggest that pig sall4b is associated with pluripotency and might be a new and useful reprogramming factor for establishing pig induced pluripotent stem cell lines.

Objective:To comprehensively evaluate the high-quality development of some tertiary public hospitals in C city, and explore the high-quality development path of municipal public hospitals, so as to provide a basis for the formulation of relevant policies.Methods:Based on the relevant policy documents of the evaluation indicators for the high-quality development of public hospitals, and around the four dimensions of medical quality, economic efficiency, sustainable development and satisfaction, the entropy weight TOPSIS-RSR method was adopted to comprehensively evaluate the high-quality development of some tertiary public hospitals in C city in 2019 and 2020. It included all five municipal comprehensive tertiary public hospitals in C city, and included one provincial and two county-level tertiary public hospitals for comparative study.Results:In 2019 and 2020, the number of medical cooperation, the surplus of income and expenditure, and the entropy weight of scientific research project funding per 100 health technicians were large, which were the key indicators to evaluate the high-quality development of public hospitals, with the values of 0.096 and 0.109, 0.119 and 0.141, 0.123 and 0.124, respectively. According to the best classification principle, the provincial, municipal and county-level public hospitals in C city could be divided into three levels of " good" , " medium" and " poor" , and the development gap between these levels was large.Conclusions:The development of municipal public hospitals in C city has achieved remarkable results, but there are still such problems as uneven distribution of medical resources, insufficient motivation for talent training, relatively lagging discipline construction, and insufficient advantages and characteristics. In this regard, we should further optimize the allocation of medical resources, improve the operation and management system, clarify the social functions of public hospitals, and scientifically allocate core resources.

Objective:To investigate the prognosis of severe hyperbilirubinemia in full-term infants who met the exchange transfusion criteria and were treated by blood exchange transfusion and phototherapy.Methods:A total of 168 full-term infants with severe hyperbilirubinemia who met the criteria for exchange transfusion and were hospitalized in the Neonatology Department of seven tertiary hospitals in Hebei Province from June 2017 to December 2018 were retrospectively included. According to the treatment protocol, they were divided into two groups: exchange transfusion group (38 cases) and phototherapy group (130 cases). Two independent sample t-test and Chi-square test were used to compare the clinical manifestations and follow-up results between the two groups. Multivariate logistic regression was used to analyze the risk factors for poor prognosis. Results:Neonatal severe hyperbilirubinemia in the exchange transfusion and phototherapy group were both mainly caused by hemolytic disease [42.1%(16/38) and 29.2%(38/130)], sepsis [28.9%(11/38) and 11.5%(15/130)] and early-onset breastfeeding jaundice [15.8%(6/38) and 11.5%(15/130)]. Total serum bilirubin level on admission in the exchange transfusion group was significantly higher than that in the phototherapy group [(531.7±141.3) vs (440.0±67.4) μmol/L, t=3.870, P<0.001]. Moreover, the percentage of patients with mild, moderate and severe acute bilirubin encephalopathy in the exchange transfusion group were higher than those in the phototherapy group [15.8%(6/38) vs 3.8%(5/130), 7.9%(3/38) vs 0.8%(1/130), 13.2%(5/38) vs 0.0%(0/130); χ2=29.119, P<0.001]. Among the 168 patients, 135 were followed up to 18-36 months of age and 12 showed poor prognosis (developmental retardation or hearing impairment) with four in the exchange transfusion group (12.9%, 4/31) and eight in the phototherapy group (7.7%, 8/104). Multivariate logistic regression analysis showed that for full-term infants with severe hyperbilirubinemia who met the exchange transfusion criteria, phototherapy alone without blood exchange transfusion as well as severe ABE were risk factors for poor prognosis ( OR=14.407, 95% CI: 1.101-88.528, P=0.042; OR=16.561, 95% CI: 4.042-67.850, P<0.001). Conclusions:Full-term infants who have severe hyperbilirubinemia and meet the exchange transfusion criteria should be actively treated with blood exchange transfusion, especially for those with severe ABE, so as to improve the prognosis.

Poria cocos is a classic Chinese medicine with homology of food and medicine,which is beneficial to water infiltration,spleen and stomach,calming the heart and calming the mind,etc.It is known as"nine Poria cocos in ten prescriptions".Poria cocos contains polysaccharide,triterpenoids and steroids,among them polysaccharide and triterpenoid are considered as the main active components.Modern studies have shown that Poria cocos polysaccharide triterpenes display pharmacological activities such as anti-tumor,immunomodulatory and anti-oxidation.The dissolution rate of poria cocos and triterpenes was low in the traditional decocting process,and the oral absorption rate of poria cocos was low,but the activity of poria cocos and triterpenes was still very good,indicating the high activity of poria cocos and triterpenes.Therefore,this paper systematically reviews the extraction and separation,structural identification,content determination,structural modification,biosynthesis,pharmacological activity and potential product development value of Poria cocos polysaccharide and triterpenoids,in order to provide literature reference for the development of Poria cocos grand health industry.

OBJECTIVETo investigate clinical characteristics and changes of pulmonary imaging of mineral oil aspiration pneumonia in children.

METHODThe clinical features, CT findings, and effects of corticosteroid therapy were analyzed in 16 children with mineral oil aspiration pneumonia, who were hospitalized in our hospital from January 2003 to July 2013.

RESULTAll patients with mineral oil aspiration pneumonia had a history of mineral oil administration.Four patients had no clinical manifestations. Ten cases presented fever, and 8 of the 10 patients had fever in 4-8 h after taking mineral oil, and the temperature was between 39-40 °C. There were wheezing in 2 cases, shortness of breath in 6 cases, cyanosis in 1 case, dyspnea in 3 cases, and moaning in 2 cases, chest pain in 1 case, headache and abnormal EEG in 1 case.Six patients had rales in lungs. Peripheral blood white cells increased in 10 cases, and C- reactive protein elevated in 7 patients. Chest CT examination showed abnormal findings in 6 children, and the earliest CT was performed within 2 h after the accident. The rest 10 children got chest X-ray, and 9 of 10 children had abnormal findings. The earliest X-ray was done within 3 h after the accident. And the remaining 1 of 10 children showed no significant changes in the first chest X-ray 2-3 h after the accident until 3 days. All of the patients received corticosteroid and antibiotic treatments, 4 cases underwent bronchoalveolar lavage, 3 patients were given albumin, 6 cases received intravenous immunoglobulin. Three cases delayed in treatment with hormone because of misdiagnosis, and 2 of them had clearly secondary infections. Twelve patients recovered completely from oil aspiration pneumonia after 8 days to 5.5 months.

CONCLUSIONOil aspiration pneumonia in children occurs in almost all cases after mineral oil aspiration. Pulmonary opacities can be found by chest CT in most patients within 24 hours after mineral oil aspiration. Corticosteroids therapy was effective for patients with exogenous lipid pneumonia, which may inhibit the inflammatory response and possible pulmonary fibrosis.
