ABSTRACT
Hospitals need to explore based on their own specifics how to establish a modern hospital governance system and how a lean hospital administration level be achieved. This paper introduced the practice and exploration of modern hospital governance system construction in Beijing Tsinghua Changgung Hospital as follows. The hospital is run by a board of administration featuring co-administration by both Beijing Municipal Hospital Administration Center and Tsinghua University; A hospital charter is developed and agreed upon to regulate decision-making, day-to-day operations and supervision; The hospital president′s responsibility is under the leadership of the hospital′s Communist Party Committee; Benefiting from best practices of Taiwan Changgung′s medical system, the hospital′s specialized medical teams and professional administrative teams operate in cooperative governance, and under professional management model and a lean operation management system. The practice and exploration of Beijing Tsinghua Changgung Hospital can serve as references for building and perfecting a modern hospital governance system.
ABSTRACT
OBJECTIVE:To provide reference for further improving the rationality of perioperative prophylactic use of antibiotics in laparoscopy surgery. METHODS:Electronic medical records and medical orders of 5 288 inpatients underwent laparoscopy surgery were collected from our hospital during Jan. 1st-Dec. 31st,2016 by using related information system software. The perioperative prophylactic use of antibiotics was investigated retrospectively. Rationality of medical orders was evaluated. RESULTS:Among 5 288 patients underwent laparoscopy surgery,1 890 patients used antibiotics for infection prevention during perioperative period. The rate of prophylactic use of antibiotics was 35.7%. The rate of prophylactic use of antibiotics in stomach,duodenum and small intestine operation was the highest(69.4%);the rate of prophylactic use of antibiotics in hepatobiliary and pancreatic surgery also reached 68.0%;prophylactic use of antibiotics was not found in the surgery of abdominal external hemia. The majority of 1 890 patients who had used antibiotics prophylactically during perioperative period used antibiotics alone(83.4%). Top 3 drugs in the list of use frequency were cefuroxime sodium(63.9%),metronidazole(13.5%)and cefotaxime sodium(11.85). There were irrational medical orders in 151 cases(8.0%)of perioperative prophylactic use of antibiotics;among prescriptions of irrational drug use,the majority was unsuitable drug selection(50.3%),followed by unsuitable drug selection among nonstandard medical orders. CONCLUSIONS:The overall situation of perioperative prophylactic use of antibiotics is basically satisfactory in laparoscopic surgery of our hospital. The rate of prophylactic use of antibiotics is relatively high in type Ⅰ incision surgery,and irrational drug use is found in some medical orders of prophylactic drug use. It is necessary to formulate regulations for prophylactic use of antibiotics in accordance with the actual situation of the hospital,strengthen medical order evaluation for perioperative prophylactic use of antibiotics in laparoscopy surgery,relevant rational drug use education.
ABSTRACT
Objective To investigate the association between the value of α-thalassemia minor and the outcomes in pregnant women.Methods A total of 445 pregnant women with α-thalassemia minor were selected as thalassemia group in the Pingguo County Maternal and Child Health Hospital of Guangxi from January 2011 to December 2015,with ratio of 1 ∶ 4 healthy pregnant women was randomly recruited as non-thalassemia group.Clinical characteristics and pregnancy outcomes of the two groups were retrospectively analyzed using methods including t test,x2 test,and logistic regression model and ROC curve.Results There were no significant differences noticed in factors as age,BMI,gestational age and educational level of the two groups.Hemoglobin of the thalassemia group was significantly lower than that of the non-thalassemia group (P＜0.001).Differences on parity,ethnicities or occupation were statistically significant.Results from univariate analysis showed that the proportions of low birth weight,small for date infant and 1 min Apgar score ＜7 were higher in the thalassemia group,but the ratio of adverse pregnancy outcomes was comparable on parameters as preterm birth,stillbirth,macrosomia.Findings from the unconditional logistic regression showed that pregnancy complicated with α-thalassemia minor appeared a risk for both newboms with low birth weight (aOR=2.29,95％CI:1.32-3.95) and small for date infant (aOR=2.11,95％ CI:1.16-3.84).The ROC curve showed that α-thalassemia minor combined with multiple indicators presented a certain predictive value on neonatal birth weight.Conclusion Pregnancy complicated with α-thalassemia minor was likely to increase the risk of birth weight loss in newborns,suggesting that prenatal care for pregnant women with thalassemia be strengthened,in order to reduce the incidence of adverse pregnancy outcomes.

ABSTRACT
Objective To explore the roles of MircroRNA-217 ( Mir-217 ) , silent information regulator 1 (Sirt1), and hypoxia-inducible factor-1α(HIF-1α)in high glucose-induced inflammation and fibrosis in rat glomerular mesangial cells( RMCs) . Methods RMCs were pre-incubated with a Sirt1 activator resveratrol prior to high glucose treatment or transfected with Sirt1 small interfering RNA( siRNA) , HIF-1αsiRNA, and Mir-217 inhibitor. Real-time PCR was used to analyze the expressions of Mir-217, Sirt1 mRNA, and HIF-1α mRNA; Western blot was used to observe the protein expressions of Sirt1, HIF-1α, connective tissue growth factor(CTGF), endothelin-1(ET-1), and fibronectin( FN) . Enzyme-linked immunosorbent assay was applied to detect protein expression of transforming growth factor-β1(TGF-β1)and vascular endothelial growth factor(VEGF). Results High glucose increased Mir-217, HIF-1α, CTGF, ET-1, FN, TGF-β1, and VEGF expressions(all P<0. 01), while decreased Sirt1 expression. In addition, Mir-217 gene silencing or 25μmol/L resveratrol suppressed high glucose-stimulated expressions of HIF-1α, CTGF, endothelin-1, FN, TGF-β1, and VEGF(all P<0. 01). Conclusion Mir-217 mediates high glucose-induced inflammation and fibrosis in RMCs via Sirt1/HIF-1αsignal pathway. This study provides new evidence to clarify the protective mechanisms of Sirt1 in diabetic nephropathy.

ABSTRACT
Objective To explore the changes in expression of Klotho, an aging-suppression protein, and neutrophil gelatinase associated lipocalin ( NGAL) and their relationship with rat mesangial cells ( RMCs) cultured with high glucose in vitro, and to explore the role played by Toll-like receptor-4 (TLR4) / nuclear factor-kB(NF-kB) p65 pathways in this process. Methods Three NGAL-siRNA sequences were designed and synthesized. The effective sequence in subsequent experiments was chosen. RMCs were preincubated with pyrrolidinedithiocarbamate (PDTC)or exogenously added Klotho prior to high glucose treatment. Realtime PCR was used to analyze Klotho, TLR4, NGAL mRNA expressions. Western blot was used to observe Klotho, TLR4,NF-kB p65, NGAL,fibronectin (FN), and connective tissue growth factor ( CTGF) protein expression. ELISA assay was used to detect monocyte chemoattractant protein-1 ( MCP-1) and CXCL5 secretions. Results High glucose suppressed Klotho expression significantly(P<0. 05) and activated TLR4 / NF-kB p65 pathway. Meanwhile,the levels of NGAL,FN,CTGF, MCP-1, and CXCL5 were highly expressed ( P < 0. 01). NGAL gene silencing obviously down-regulated the increased expressions of FN, CTGF, MCP-1, and CXCL5 ( P < 0. 01). After PDTC treatment the overexpression of NGAL protein was markedly lowered(P<0. 01). In addition, Klotho treatment significantly inhibited the activity of TLR4 /NF-kB p65 pathways and down-regulated the expressions of NGAL, FN, CTGF, MCP-1 and CXCL5 stimulated by high glucose(P<0. 01). Conclusion Klotho inhibits the activity of TLR4 / NF-kB p65 pathways and thus inhibits NGAL expression in RMCs cultured with high glucose in vitro. And then it suppresses the expressions of FN, CTGF, MCP-1, and CXCL5. This provides a new basis to illustrate the protection mechanism of the anti-aging protein Klotho in diabetic nephropathy, and may provide new ideas and therapeutic targets for prevention and treatment.

ABSTRACT
Objective To examine whether alpha lipoic acid (LA) regulates high glucose-induced mesangial cell proliferation via mammalian target of rapamycin (mTOR) signaling.Methods The cell proliferation and cycle were determined by methylthiazoletetrazolium(MTT) assay and flow cytometry,respectively.The mRNA expression of AMP-activated protein kinase(AMPK) was detected by realtime PCR.The phosphorylation levels of protein kinase B (Akt),mTOR,eukaryotic translation initiation factor 4E binding protein 1 (4EBP1),and 70S6 kinase (p70S6K) were measured by Western blot.Results 0.25 mmol/L LA promoted high glucose-sitmulated rat mesangial cell proliferation(P＜0.01) and entry of cell cycle into S phase(P＜0.01),along with increased phosphorylation levels of Akt,mTOR,p70S6K,and 4EBP1 (P＜0.05).These effects of 0.25 mmol/L LA disappeared when Akt activity was inhibited.On the contrary,1.0 mmol/L LA inhibited high glucose-induced cell proliferation(P＜0.01) and entry of cell cycle into S phase(P＜0.01),with the decreased phosphorylation levels of mTOR,p70S6K,and 4EBP1 (P＜ 0.05) and the enhanced activity of AMPK(P＜0.01).These effects of 1.0 mmol/L LA were prevented when AMPK activity was inhibited.Conclusions LA dose-dependently regulates mesangial cell proliferation induced by glucose via mTOR signaling pathway.
