Organic anion transporting polypeptides (OATP), a member of solute carrier (SLC) superfamily, is considered as an important transmembrane uptake transporters. OATP is involved in the transport of a variety of endo- and xenobiotics (bile acids, bilirubin, prostaglandin, thyroid hormones, steroid hormone conjugates), drugs and toxins in a Na+ and ATP independent manner. Multiple factors (eg. hormones, proinflammatory cytokines, drugs) can affect the distribution, expression and activity of OATPs, leading to an altered accumulation of OATP substrates and related food-drug and drug-drug interactions. Changes in the distribution and expression of OATPs in malignant tissues may be related to the pathological process of cancer, while the modulation epigenetic mechanism also contributes to its distribution patterns. This review describes the factors that can affect the expression or function of OATPs, which may provide a valuable reference for drug development and the clarification of pathogenesis.

Objective:Using a diagnostic test research,to explore the reliability and validity of the Patient Health Questionnaire (PHQ-9)on screening of depressive disorders in general hospital,and to determine the cut points for depressions with different severities.Methods:Three hundred and nineteen help-seekers (n =319)con-sulting the outpatient department of psychiatry in a general hospital were collected continuously.Among them,80 were people without any psychiatric diagnosis,239 were patients with mental disorders.All of subjects were asked to fulfill PHQ-9,and were assessed by psychiatrist with Mini-International Neuropsychiatric Interview (M.I.N.I.) and Hamilton rating scale for depression.M.I.N.I.was gold standard to diagnose depressive disorder,HRSD was used to assess the illness severity.Result:Factor analysis showed good structure validity of PHQ-9.46 patients were diagnosed depressive disorders.The area under the receiver operator characteristic analysis (ROC)of PHQ-9 was 0.94 (95%CI:0.91 -0.97)for depressive disorders.With 15 as the critical value for depression screening,the sen-sitivity was 0.83 and specificity was 0.90,respectively.By the result of HRSD as the standard to rank different lev-els of depression,the cut points of PHQ-9 for mild,moderate,and severe depression was 6,12,and 15.The consis-tency between results of PHQ-9 (with cut points of 6,12,15)and HRSD was moderate (with kappa =0.49).The kappa between results of PHQ-9 (with recommended cut points of 5,10,and 15)and HRSD was 0.46.Cronbach αcoefficient of PHQ-9 was 0.892.Conclusion:It suggests that PHQ-9 has satisfying reliability and validity,and is applicable for screening depression and assessment of its severity of outpatients in general hospital.The recommen-ded cut points of PHQ-9 are applicable to depressive outpatients in general hospital in China.

Different from Westerners,intracranial atherosclerosis (ICAS) is a main cause for acute ischemic stroke in Eastern population.Studies have shown that ICAS is associated with the risk factors including metabolic syndrome,dyslipidemia,diabetes mellitus,and inflammation.Adiponectin is involved in oxidative stress and glycolipid metabolism,its reduced level is the most important risk factor for metabolic syndrome and the most prominent inflammatory markers.Numerous studies have suggested that adiponectin is associated with cardiovascular diseases,and it is used as a preventive marker.In recent years,the relationship between adiponectin and ICAS has become a hot research topic.This article mainly reviews the roles of adiponectin in ICAS.

Objective To investigate the therapeutic effects and adverse drug reactions of different doses of rosuvastatin in patients with acute ST segment elevation myocardial infarction (STEMI). Methods A total of 115 patients with STEMI were collected from Department of Cardiology, the Second Hospital of Tianjin Medical University. According to different oral doses of rosuvastatin, patients were divided into two groups including 5 mg/d rosuvastatin treatment group (low-dose group, n=44) and 10 mg/d Rosuvastatin treatment group (moderate-dose group, n=71). Patients of two groups were treated with Rosuvastatin at least 1 month after discharge. Data of total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed and compared before and after treatment between two groups. The major cardiovascular adverse events (MACE) and adverse reactions were recorded in two groups of patients. Results There were no significant differences in blood lipid and liver function levels before and after one month treatment between the two groups. After one month treatment, levels of TC, LDL-C, ALT and AST were significantly decreased in both groups of patients compared with those before treatment (P<0.05). There were no significant differences in levels of TG, and HDL-C before and after treatment between two groups. The incidence of MACE (heart failure and angina pectoris) was significantly lower in moderate-dose group than that in low-dose group (P<0.05). There was no significant difference in the proportion of malignant arrhythmia between the moderate-dose group and the low-dose group (P<0.05). No target vessel repair and death were found in the two groups. No obvious adverse drug reactions were found during the follow-up period. Conclusion The hypolipidemic effects are epuivalent between 5 mg/d rosuvastatin and 10 mg/d on the basis of conventional treatment for STEMI patients, but the moderate dose can reduce the incidence of MACE and improve prognosis.

Objective To explore the clinical diagnosis of tetralogy of Fallot( TOF) children with concurrent DiGeorge syndrome ( DGS ) . Methods Retrospective analyses were conducted for the clinical characteristics of 715 TOF children with concurrent DGS at Henan Provincial People′s Hospital and the Third Affiliated Hospital of Zheng-zhou University from January of 2008 to October of 2014. Among them,there were 78 definite cases of thymic aplasia (DGS group),including 45 boys and 33 girls with an age range of(9. 12±4. 35) months and a body mass range of (7. 28±2. 34) kg. And the remainder was designated as non-DGS group(NDGS group),including 387 boys and 250 girls with an age range of(8. 21±5. 61) months and a body mass range of(8. 19±3. 47) kg. In DGS group,genetic screening uncovered 10 cases of chromosome 22q11. 2 gene deletion. And based upon this result,DGS group was fur-ther divided into genetic and clinical diagnosis subgroups. The genetic diagnosis group had 10 cases,including 6 boys and 4 girls with an age range of(8. 12±4. 15) months and a body mass range of(6. 28±2. 74) kg,the clinical diagnosis group had 68 cases,including 39 boys and 29 girls with an age range of(8. 19±4. 37) months and a body mass range of (7. 05±2. 39) kg. Results No statistical difference existed in age,body mass or preoperative developmental status of pulmonary vasculature between DGS group and NDGS group(P>0. 05). And the preoperative incidence of recurrent pneumonia was obviously higher in DGS group than that in NDGS group(P<0. 001). The probability of concurrent hy-pocalcemia and facial malformation was higher in DGS group than that in NDGS group. However,there was no statistical difference(P>0. 05). And an inter-group comparison of T lymphocyte immunity defect had no statistical difference(P>0. 05). The duration of on-machine and intensive care unit stay was markedly longer in DGS group than that in NDGS group(P<0. 001). And the probability of concurrent hypocalcemia and facial malformation was higher in genetic diag-nosis subgroup than that in clinical diagnosis subgroup. However,there was no statistical difference(P>0. 05). And an inter-group comparison of T lymphocyte immunity defect had no statistical difference ( P>0. 05 ) . Conclusions With diverse clinical manifestations,DGS patients may have non-specific findings of cellular immunity defect,hypocalcemia or facial malformation. TOF children with concurrent thymic aplasia should raise an alert so that effective interventions may be adopted to boost their long-term quality of life.

A novel targeting drug carrier (FA-BO-PAMAM) based on the PAMAM G5 dendrimer modified with borneol (BO) and folic acid (FA) molecules on the periphery and doxorubicin (DOX) loaded in the interior was designed and prepared to achieve the purposes of enhancing the blood-brain barrier (BBB) transportation and improving the drug accumulation in the glioma cells. 1H NMR was used to confirm the synthesis of FA-BO-PAMAM; its morphology and mean size were analyzed by dynamic light scattering (DLS) and transmission electron microscope (TEM). Based on the HBMEC and C6 cells, cytotoxicity assay, transport across the BBB, cellular uptake and anti-tumor activity in vitro were investigated to evaluate the properties of nanocarriers in vitro. The results showed that the nanocarrier of FA-BO-PAMAM was successfully synthesized, which was spherical in morphology with the average size of (22.28 ± 0.42) nm, and zeta potential of (7.6 ± 0.89) mV. Cytotoxicity and transport across the BBB assay showed that BO-modified conjugates decreased the cytotoxicity of PAMAM against both HBMEC and C6 cells and exhibited higher BBB transportation ability than BO-unmodified conjugates; moreover, modification with FA increased the total uptake of DOX by C6 cells and enhanced the cytotoxicity of DOX-polymer against C6 cells. Therefore, FA-BO-PAMAM is a promising nanodrug delivery system in employing PAMAM as a drug carrier and treatment for brain glioma.

Objective To explore the status quo and the correlation of professional practice environment and job burnout in head nurses. Methods Totally 646 head nurses from city state hospitals of Hunan Province was selected by cluster sampling method. Participants were investigated by using the Chinese Version of Profession Practice Environment Scale for Head Nurses and Maslach Burnout Inventory. Results The professional environment score was 215.95±22.81, which was in the moderate level. The score of emotional exhaustion (EE) in head nurses was 24.56 ± 10.64, depersonalization (DP) was 8.92 ± 4.17 and personal accomplishment (PA) was 35.55±13.08, all stating moderate burnout. Meanwhile, the scores of EE and DP were negatively correlated with professional practice environment (r=-0.350--0.161, P≤0.01), while the PA was positively correlated with professional practice environment (r=0.078- 0.271, P≤0.01). Conclusions Professional practice environment in head nurses is correlated with job burnout. Hospital leaders should pay more attention to head nurses′professional practice environment to decrease job burnout in head nurses.

This study aimed at investigating the inhibitory effects and the anti-tumor mechanisms of co-adminis-tration of fusion proteins mGM-CSF/βhCG ( GC ) and hVEGF121/βhCG ( VC ) on RM-1 prostatic cancer and B16 F10 melanoma in the C57 BL/6 J mouse model. Two recombinant stains containing pET-28 a-mGM-CSF-X10-βhCGCTP37 and pET-28 a-VEGF-M2-X10-βhCG-CTP37 were induced by lactose to express fusion proteins. The fusion proteins were separated and purified to prepare the anti-tumor protein vaccines ( VC protein vaccine and GC protein vaccine) , which were then mixed to prepare a combined protein vaccine named VGC protein vac-cine. The prostatic cancer and melanoma tumor-bearing mice C57 BL/6 J were immunized with described vac-cines, then the growth of each tumor was measured;splenocyte proliferation of immunized mice was detected;and the cytotoxic effects of the vaccine on tumor cells were tested. After that, the in vivo concentrations of IFN-γ and anti-hVEGF antibodies were investigated by ELISA. The difference between each experimental group and normal saline group ( NS) was statistically significant in both tumor-bearing mouse models ( P <0. 05) respectively. Besides, VGC group exhibited significantly better anti-tumor effect compared with the GC and VC groups with the anti-tumor rate ( 41. 7 ± 0. 83)% and ( 46. 4 ± 1. 27)% for prostatic cancer and melanoma tumor, respectively. The co-administration of the two proteins, VC and GC, could inhibit the growth of RM-1 prostatic tumor and B16F10 melanoma effectively via anti-tumor immunity and anti-tumor angiogenesis.
