Aim To study the transport of geniposide and geniposide in Zhizi Bopi Decoction in MDCK cell membrane model. Methods The safety concentration of geniposide and Zhizi Bopi Decoction in MDCK cells were determined by MTT assay. Then the MDCK cell membrane model was used to investigate the transport of drugs. Firstly, the effects of time, drug concentra-tion, P-gp inhibitor and EDTA on the absorption and transport of geniposide were studied systematically. Secondly, the differences were compared between the transport of the same concentration of geniposide as single compound and that in Zhizi Bopi Decoction in MDCK cell model. The drug concentration was deter-mined by high performance liquid chromatography ( HPLC) to calculate the apparent permeability coeffi-cient (Papp). Results Geniposide transport in MDCK cell monolayer was time and concentration dependent. P-gp inhibitors had no significant effect on its transport and the transport of geniposide was enhanced by ED-TA. The absorption Papp of different concentrations of geniposide in Zhizi Bopi Decoction were ( 8. 96 ± 0. 35 ) × 10 -7 cm · s-1 , ( 8. 95 ± 0. 38 ) × 10 -7 cm · s-1 and (9. 16 ± 0. 30) × 10 -7 cm·s-1, significantly higher than the absorption Papp of geniposide as single compound(5. 85 ± 0. 44) × 10 -7 cm·s-1, (6. 88 ± 0. 38) × 10 -7 cm·s-1 and (6. 31 ± 0. 19) × 10 -7 cm ·s-1 ( P<0. 05 ) . Conclusion The transport of ge-niposide in MDCK cell membrane model is passive transport and is not affected by P-gp. Geniposide may transport via the paracellular route. The Zhizi Bopi De-coction can increase the absorption of geniposide.

Objective To investigate the clinical value of urinaryα1-acid glycoprotein (AAG)in the early diagnosis of diabetic nephropathy(DN).Methods 266 cases of diabetic patients in Drum Tower Hospital Affiliated to Medical School of Nanjing University from May 2013 to October 2014 were recruited,and patients were divided into four groups based on the urine al-bumin/creatinine (ACR)levels,as follows:non-diabetic nephropathy group (Non-DN)152 cases,low urinary albumin/cre-atinine group (LUA)49 cases,high urinary albumin/creatinine group (HUA)32 cases,and very high urinary albumin/cre-atinine group (VHUA)33 cases.63 cases of healthy subjects (NC group)and 66 cases of fracture patients (stress group) were recruited as control group.The urinary AAG and other biochemical indicators were measured for all subjects.Results The level of urinary AAG in DN group was significantly higher than that in stress group,Non-DN group and NC group (t=7.951,7.985,8.021,P <0.05),and gradually increased from LUA,HUA to VHUA group (P <0.05).The urinary AAG level was positively correlated with UA,Cr,CRP and ACR (r=0.169,0.286,0.373,0.606,P <0.01).Stepwise logistic re-gression analysis showed that the urinary AAG was the independent risk factor of DN (P <0.05).Conclusion The level of urinary AAG has good application value in the early diagnosis and monitoring progression of DN.

Objective:To compare the concordance between subjective experience and clinician-rated in different treatment phrase of elderly patients with depressive disorder,and to explore the relevant factors.Methods:Sixty-nine consecutive elderly patiems with depressive disorder diagnosed with International Classification of Diseases-10 criteria were included.The Visual Scale for Depression(VSD) were used to evaluate subjective experience of depression,while the Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),Minimum Mental State Examination (MMSE) were used by clinician to evaluate depression symptom,anxiety symptom and cognition at baseline,2-,4-and 52-week of the treatment respectively.Results:Compared with baseline,VSD scores were increased at 2 weeks and 4 weeks [(2.7 ± 1.6),(5.3 ± 2.0) vs.(7.0 ± 1.8),P ＜ 0.001],HAMD scores were decreased at 2 weeks and 4 weeks [(36 ± 11),(17 ±9) vs.(9 ±8),P ＜0.001],HAMA scores were decreased at 2 weeks and 4 weeks [(27 ± 10),(14 ±8) vs.(7 ±6),P ＜0.001].No significant differences were found between 4 weeks and 52 weeks.There was no correlation between VSD and HAMD scores at baseline and 2 weeks.There were significant correlations among scores of VSD and HAMD(r =-0.31,-0.74,Ps ＜ 0.05),HAMA (r =-0.36,-0.76,Ps ＜ 0.05) at 4 weeks and 52 weeks.Using logistic regression analysis,the concordance between VSD and HAMD related with the factors of HAMD,higher scores of anxiety/somatization factor were associated with lower concordance (OR =0.87),and higher scores of weight factor (OR =1.86),diurnal variation factor (OR =2.00),hopelessness factor (OR =1.13) were associated with higher concordance.Conclusion:Compared with acute depression phase,concordance between subjective experience and clinician-rated for depression may be higher at depression remission phase in elderly patients with depression,which suggests that characteristics of depression symptom may have a certain impact on the self-awareness for depression experience.

Objective To conduct a meta-analysis to evaluate the outcomes of donation after cardiac death (DCD) compared with donation after brain death (DBD) liver transplantatior.Methods The MELDINE (1950-2011),EMBASE,and Cochrane Library databases were searched.All original single institution studies reporting outcomes of comparing donation after DCD and DBD liver transplantation were considered.A meta-analysis of complication incidence and patients/grafts survival after liver transplantation was conducted.Odds ratios (OR) and 95 ％ confidence intervals (CI) based on random effects models were calculated.Results Thirteen studies,all retrospective cohort studies,involving 5867 DCD and 619 DBD recipients,were included.DCD recipients had a 2.5 times increased odds of biliary complications (95 ％ CI =2.0～3.12),an 11.24 times increased odds of ischemic cholangiopathy (IC) (95 ％ CI =5.58 ～ 22.64 ),and a 2.12 times increased odds of primary nonfunction (PNF).DCD recipients also experienced lower odds of 1-year patient survival (OR =0.78,95 ％ CI=0.59～1.02),83.8 ％,87.2 ％,separately,and 1-year graft survival (OR=0.55,95％ CI=0.45～0.68),72.2 ％ and 82.4 ％,separately.Three-year patient survival was present in 81.5 ％ of DCD vs 78.9 ％ of DBD,which has no significant difference.The 3-year graft survival was lower inDCD than that in DBD (OR =0.73,95 ％ CI =0.56～0.94),69.5 ％ and 73.6％,separately.Conclusion DCD liver transplantation is associated with higher risks of biliary complications.But regarding the comparable general outcomes with DBD transplantation,DCD could be a source of liver.

Objective · To evaluate the association between the abnormal maternal serum markers of alpha fetoprotein (AFP), human chorionic gonadotrophin (hCG) and unconjugated estriol (uE3) in the second trimester screening and the adverse obstetric outcomes other than trisomy 21 (T21),trisomy 18 (T18) and open neural tube defects (ONTD), and to provide local data for supporting evidence based clinical managements. Methods · A retrospective cohort study was performed in the women who received second trimester maternal serum screening in the International Peace Maternal and Child Health Hospital between 2012 and 2014, with naturally conceived singleton pregnancies. Obstetric outcomes were followed up by searching electronic medical records within the hospital. Abnormal level of marker was defined as a MOM value ≥ 99th (P99) or ≤ 1st percentile (P1) of the overall screened population. Incidence of an adverse obstetric outcome was compared between the groups with abnormal markers and the control with all markers in normal. Results · ① A total of 25616 pregnancies were included in this study, in which 4526 were identified as having various adverse obstetric outcomes. Among them 4143 pregnancies were with isolated and 383 pregnancies were with co-occurring two or more adverse outcomes. ② When compared to pregnancies with normal levels of all three serum markers, pregnancies with decreased AFP or decreased hCG did not show associations with any adverse obstetric outcomes. However, pregnancies with increased AFP, increased hCG or decreased uE3 were at increased risk for a variety of abnormal pregnancy outcome. In 18 pregnancies with an outcome of fetal chromosomal abnormalities other than T21 and T18, 9 presented with either increased AFP, increased hCG or decreased uE3, with relative risk ratios of 13.33、35.00 and 59.00, respectively. ③ The performance of those markers tended to be improved in a subset of adverse obstetric outcomes, including low birth weight

Objective To study the iodine nutritional status and the thyroid function of pregnant women during different periods,and provide scientific basis for iodine supplementation.Methods Totally 728 pregnant women who visited the obstetric outpatient of Nanjing Drum Tower Hospital for routine prenatal care from December 2014 to August 2016 were recruited in this study,and at the same time 182 non-pregnant women were recruited as control group.The thyroid stimulating hormone (TSH) and free thyroxine (FT4) were measured by Roche 601.The urinary iodine level was measured by SR-I-100 kit.Results The median urinary iodine of 728 pregnant women was 168.24 g/L,and the median urinary iodine of those women in the T1,T2 and T3 period were 186.31,162.65 and 148.76 g/L,respectively.The TSH at T1 period was lower than T2 and T3 period (t=3.429,3.135,P＜0.05).The FT4 at T1 period was higher than T2 and T3 period (t=5.251,5.965,P＜ 0.05).The prevalence rate of thyroid disease in normal urinary iodine group was lower than that in low urinary iodine group and high urinary iodine group (x2 =4.139,4.131,P＜0.05).Conclusion There was no iodine deficiency among those pregnant women groups,but only 34.75 ％ individuals reached the appropriate iodine nutritional level,and the ratio of iodine insufficient increased with the extension of pregnancy.The whole prevalence rate of thyroid disease in abnormal urinary iodine pregnant women was obviously higher than that in normal.It is necessary to improve the pregnant women's knowledge of iodine nutrition,moreover it is suggested that urinary iodine monitoring and thyroid function should be conducted in pregnant women.

Objective To explore the molecular mechanisms of carbapenem-resistant Klebsiella pneumoniae.Methods Carba NP confirmatory test were used to detect carbapenemases.Carbapenemase genes,ESBL genes and plasmid-mediated AmpC genes were amplified by polymerase chain reaction (PCR).The genetic correlation analysis was carried out by using multiple sequence type (MLST).Results 42 out of the 50 carbapenem-resistant Klebsiella pneumoniae strains were KPC-2-positive strains,1 strain was positive for NDM-1,the other 7 strains were not detected for any carbapenemase genes.The percentages of KPC-2-positive Klebsiella pneumoniae with the bla CTX-M,bla SHV,bla TEM,bla DHA were 21.5 ％,42.9 ％,69.1％ and 4.8％ respectively.The results of MLST showed that 37 out of 42 KPC-2 positive strains were ST11.Conclusion The production of KPC-2 is the main mechanism of Klebsiella pneumoniae resistance to carbapenem and there is an outbreak of ST11 KPC-2 Klebsiella pneumoniae in this hospital.

Objective To investigate the clinical and angiographic characteristics of no reflow phenomenon after primary percutaneous coronary intervention (PCI) with acute myocardial infarction (AMI).Methods A total of 319 patients with AMI undergoing primary-PCI was divided into no-reflow and normal reflow groups.The incidence of no-reflow phenomenon,the clinical date,angiography findings,and surgical date were compared between two groups.Results No-reflow phenomenon occurred in forty(13.4％)of the patients after primary PCI.There was dramatic difference in combined hyperlipidemia,angina pectoris history before AMI,heart function ≥2 grades on admission,the length of the vascular lesions,vascular stenosis degree,blood clot load level,coronary artery opening time,and the expansion of the balloon between no-reflow and normal blood flow groups.Multiple logistic regression analysis identified that angina pectoris history before AMI,heart function classification on admission,high thrombus burden,the expansion of the balloon,and coronary artery opening time on angiography as independent predictors of no-reflow phenomenon.Conclusions The occurrence of no-reflow phenomenon after primary PCI was associated with high cholesterol history,no history of pre-infarction angina,heart function classification on admission,long vascular lesions,narrow degree of heavy,blood clots in the high load,coronary artery opened long time,and the expansion of the balloon more frequently.
