Objective To raise the awareness of acute kidney injury (AKI) and improve the level of diagnosis.Methods All the hospitalized adult patients in the Affiliated People's Hospital of Shanxi Medical University from January 2012 to July 2013 were screened.Those patients diagnosed as AKI were retrospectively analyzed in terms of incidence,the rate of missed diagnosis,etiology,distribution and prognosis of AKI.Results (1) The incidence of AKI in the patients was 0.67％ (381/56 835),the ratio of male to female was 1.91 ∶ 1,and the average age was (63.45±16.95) years.(2)There were 321 cases diagnosed as pre-renal AKI (84.25％),42 cases diagnosed as renal AKI (11.02％) and 18 cases diagnosed as post-renal AKI (4.72％).(3)There were 189 cases(49.61％) missed diagnosed among all the screened cases.The rates of missed diagnosis in neurosurgery,general surgery and cardiac surgery department was 62.96％,59.09％ and 50.00％,in cardiology,respiratory and neurology department was 50.00％,50.00％ and 45.45％ respectively.(4) Multivariate Logistic regression analysis showed that hypertension [odds ratio(OR)=1.631],renal replacement therapy(RRT)(OR=23.256) and oliguria history (OR=1.936) were independent risk factors of missed AKI diagnosis.Conclusion The missed diagnosis rate of AKI is high and has certain characteristics in different departments.Hypertension,RRT and oliguria history are independent impact factors of missed AKI diagnosis.

In this study, we investigate the bioaccessibility of heavy metals (Cu, Pb, As, Cd and Hg) in wild Artemisia annua and use target hazard quotients (THQ) proposed by US Environmental Protection Agency to assess the health risk under the heavy metal exposure. The results showed that the bioaccessibility of Cu, Pb, As, Cd and Hg in A. annua are 0.77, 0.66, 0.46, 0.68 and 0, respectively, and that the value of THQ for adults and children were 0.030 and 0.025 calculated by risk assessment model. The results indicated that the heavy metals in A. annua were not able to be completely absorbed by human body and that their contents were in a safe range. In this study, by combining the bioavailability of heavy metal and health risk assessment, we assessed the security of heavy metals of wild A. annua, which will provide reference for the standard of heavy metals for medicinal materials.

AIMTo study the effect of hyaluronic acid chitosan-based microemulsion (HAC-ME) on the permeability of blood brain barrier( BBB) by using Evans blue (EB) as the indicator.

METHODSA formamide extraction-ultraviolet spectrophotometry method was employed to determine the concentrations of EB in each of the tissues. The in vivo distribution of HAC-ME groups containing EB in mice and the fluorescence intensity and diffusion domain of brain slices were all studied.

RESULTSContrasting to the common microemulsion (ME), HAC-ME at the lower concentration of HAC (<5 mg x mL(-1)) could further improve the transporting of EB across the BBB while EB concentration in other tissues decreased, and Tmax was delayed about 30 min.

CONCLUSIONHAC-ME could facilitate the transporting of EB across the BBB and it was concentration dependent. While the brain targeting absorptive capability of HAC-ME was enhanced.

OBJECTIVETo investigate whether programmed death ligand 1 (PD-L1) expressed in the periodontal tissue of chronic periodontitis and the correlativity of PD-L1 and different degrees of chronic periodontitis, provide experience for immunoregulation mechanism, clinical treatment and prognosis of chronic periodontitis.

METHODSGingiva and periodontal tissue of healthy people and chronic periodontitis patients were collected. Based on clinical probing, periodontal tissue were classified into three groups: periodontal tissues of healthy people, periodontal tissue of mild chronic periodontitis, periodontal tissue of severe chronic periodontitis. Fluorescent quantitation polymerase chain reaction was applied to explore the expression of PD-L1 mRNA in the periodontal tissue of the different groups. Western blot and immunohistochemistry method were utilized to test the expression of PD-L1 protein in the periodontal tissue of the different groups. Combining with clinical image data, the relationship between differentially expressions of PD-L1 and different degrees of chronic periodontitis was analyzed.

RESULTSThe relative expression quantity of PD-L1 in the periodontal tissue of the mild chronic periodontitis was significantly higher that of the severe chronic periodontitis (P<0.01). The relative expression quantity of PD-L1 in the periodontal tissue of healthy subjects and severe chronic periodontitis had no statistical significance (P>0.05).

CONCLUSIONThe expression of PD-L1 in the periodontal tissue negativelv regulates inflammatory periodontal tissue damage.

OBJECTIVETo observe the effect of Yiguan Decoction (YGD) on differentiation of bone marrow mesenchymal stem cells (BMSCs) into hepatocyte-like cells in vitro.

METHODSRat BMSCs were isolated using whole bone marrow adherent method. The properties of BMSCs were identified by analyzing the expression of surface cytokines by flow cytometry. The third passage cells were differentiated into fat cells to identify their features. BMSCs were incubated with hepatocyte growth factor (HGF) plus fibroblast growth factor 4 (FGF4) or YGD containing serum YGD for 21 days. The mRNA expression of alpha-fetoprotein (alphaAFP), albumin (Alb), and hepatocyte nuclear factor 4alpha (HNF4alpha) were detected by real time PCR. Expression of AFP and cytokeratin 18 (CK18) protein was detected by cell immunofluorescence. Glycogen synthesis was observed using periodic acid-Schiff stain (PAS). CK18, Wnt 3alpha, and alphacatenin protein expressions were detected by Western blot.

RESULTSHigh expression of CD90, CD29, and CD44, and low expression of CD34 and CD11b were observed in BMSCs isolated by whole bone mar- row adherent method, and numerous lipid droplets were observed in BMSCs using oil red O staining. Both YGD containing serum and growth factor stimulated the expression levels of Alb, AFP, HNF4alpha mRNA and CK18 protein. The down-regulated expression of Wnt 3alpha and beta-catenin could be detected at 21 days after induction. The synthesized glycogen granule could be seen. Down-regulated Wnt 3alpha and beta-catenin expression could also be observed.

CONCLUSIONYGD could induce the differentiation of rat BMSCs into hepatocyte-like cells, which was related to down-regulating Wnt/beta-catenin signal pathway.
