To explore the clinical significance of serum cardiac troponin I (cTnI) for the detection of myocardial injury in children with Kawasaki disease (KD) in acute stage, the levels of serum cTn I, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactic dehydrogenase (LDH) and glutamic oxalacetic transaminase (GOT) were determined in 40 children with KD and 23 controlled children without heart disease, respectively. The results showed that the levels of serum cTn I and CK-MB in the KD group were significantly higher than those in the controlled group (P＜0.001),while no obviously differences of CK, LDH and GOT were noticed between two groups (P＞0.05). cTn I was more sensitive comparing to CK-MB for the detection of myocardial injury (P＜0.05). It is concluded that the determination of cTn I and CK-MB will be available for the diagnosis of myocardial injury in children with KD in acute stage, and the determination of cTn I is more sensitivity and specificity comparing to CK-MB.

The present study was aimed at the comparison of the pharmacokinetics of pure chlorogenic acid and extract of Solanum lyratum Thunb. The animals were allocated to two groups, and were administered chlorogenic acid or extract of S. lyratum Thunb. at a dose of 50.0 mg/kg orally. Blood samples were collected up to 8 h post-dosing. Plasma chlorogenic acid analyses were performed using an HPLC method with UV detector. The pharmacokinetic parameters were evaluated using non-compartmental assessment. Significant differences existed in the two groups for AUC0-t, AUC0-∞ and CLz/F. The reliable HPLC method was successfully applied to the determination of chlorogenic acid in rat plasma at dosage of 50.0 mg/kg.

Objective To explore the effects of human umbilical cord mesenchymal stem cells (HUC?MSCs) on podocytic apoptosis and injury induced by high glucose (HG) and the underlying mechanisms. Methods Podocytes were divided into six groups according to treatment: ⑴ normal glucose group (NG);⑵high glucose group (HG);⑶mannitol control group (NG+Ma);⑷HUC?MSC co?culture group (HUC?MSCs); ⑸ recombinant human hepatocyte growth factor treatment group (rhHGF);⑹ neutralizing antibody group(HGF?NtAb). Cytometry and Hoechst staining were used to detect the apoptosis rates. Western blot was used to measure the ratio of active PARP to total PARP and the level of Bcl?2. Immunofluorescence was used to study podocytic apoptosis and injury. Neutralizing antibody (NtAb) was used to block its function and the recombinant cytokine was added to induce its function. Results High glucose induced podocytic apoptosis in a time?dependent manner, HUC?MSCs co?culture decreased the podocytic apoptosis rate and the expression of PARP (all P﹤0.05), increased the expression of Bcl?2, prevented the reduced expression and maintained the normal arrangement of podocytic podoplanin. The rhHGF prevented podocytic apoptosis and injury similarly to HUC?MSCs, the beneficial effect of HUC?MSC decreased when blockade of HGF. Conclusions HUC?MSCs co?culture ameliorates podocytic apoptosis and injure induced by HG, probably through secreting soluble HGF.

Objective To investigate the clinical characteristics of acute pulmonary embolism in the elderly and its differences between the elderly and non-elderly patients,and explore the predictive effect of red blood cell distribution width(RDW)on chronic thromboembolic pulmonary hypertension (CTEPH)in patients with acute pulmonary embolism.Methods A total of 129 consecutive patients with acute pulmonary embolism admitted into Affiliated Hospital of Binzhou Medical College were selected from Jan.2009 to Dec.2013.Clinical data including the basic data,blood routine test,blood gas analysis,Doppler echocardiography during admission were retrospectively analyzed.All the patients were followed-up.Ancillary findings and changes of the disease were recorded in detail during the follow-up period.SPSS 19.0 was used to analyze the results.Results The incidences of CEPPH and venous thromboembolism(VTE)in APE patients were higher in the elderly than in non-elderly.The mean RDW and pulmonary arterial systolic pressure on admission in APE patients were higher in the elderly than in non-elderly [(14.22±2.11)％ vs.(13.48± 1.69)％,P=0.033,for mean RDW] and [(54.82± 21.77)mmHg vs.(42.20 ± 19.36) mmHg,P=0.010 for pulmonary arterial systolic pressure].The mean RDW was higher in CTEPH patients than in patients without CTEPH [(16.79 ± 3.08) ％ vs.(13.68± 1.68)％,P=0.016].Multivariate Logistic analyses showed that the increased RDW level was an independent risk factors for CTEPH in APE patients(OR=1.535,95％ CI:1.094-2.155,P=0.013).The area under receiver operating characteristics curve(AUC)of RDW level for predicting CTEPH in APE patients was 0.856(95％ CI:0.706-0.987,P＜0.001),the corresponding cut-off point was 14.85％,and the sensitivity and specificity were 88.9％ and 87.5％ respectively.Conclusions The increased RDW level could predict the risk of CTEPH to a certain extent in APE patients.

Objective To evaluate volume doubling time (VDT) and net mass doubling time of tumor (nMDT) of pulmonary pure ground glass nodules (PGGN) of different pathological types and to investigate whether VDT and nMDT can help to differentiate invasive pulmonary adenocarcinomas from minimally invasive adenocarcinomas and preinvasive lesions.Methods Fifty-one pathologically confirmed pGGNs in 46 patients were retrospectively evaluated,in whom at least two HRCT scans were obtained preoperatively (median scan times,3 times;range,2-6 times) with 1-month or longer follow-up interval (median follow-up interval,251 days;range,30-1 552 days).According to the rechecked results of the postoperative pathological section,51 pGGNs were divided into two groups:group A,invasive adenocarcinoma (IAC),30 pGGNs (58.8％);group B,21 pGGNs (41.2％),including 8 minimally invasive adenocarcinoma (MIA),7 adenocarcinomas in situ (AIS) and 6 atypical adenomatous hyperplasia (AAH).The volume,cumulative percentage of volume growth and VDTs of pGGNs were automatically acquired by Lung VCAR (advantage windows 4.6,GE HealthCare).Subsequently,the mass,cumulative percentage of mass growth and nMDTs of pGGNs were calculated.The count data and measurement data between two groups were compared using Fisher exact probability and Mann-Whitney U test,respectively.A pairwise comparision were performed by using Wilcoxon signed-rank test.Subsequently,the receiver operating characteristic (ROC) curve was used to determine the optimal cut-off values of VDT and nMDT for the differential diagnosis of IAC and MIA/AIS/AAH,and calculated the area under the curve (AUC).Results The median VDT and nMDT of 51 pGGNs were 1 854.11 days (range,165.22—+∞ days) and 1 138.45 days (range,95.92—+ ∞ days),respectively.The median nMDT was shorter than the median VDT,and the difference was significant (Z=-2.444,P=-0.O15).The median VDTs of IAC and MIA/AIS/AAH were 847.07 days (165.22—+∞ days) and 4 460.09 days (691.14—+∞ days),respectively.The median nMDTs of IAC,MIA/AIS/AAH were 769.93 days (95.92—+∞ days) and 3814.77 days (611.56—+∞ days),respectively.The median VDT and nMDT of IAC were significantly shorter than those of MIA/AIS/AAH (Z=-3.443,-3.860,P＜ 0.01,respectively).Differentiating IAC from MIA/AIS/AAH,the optimal cutoff value of VDT was 2095.86 days (sensitivity,71.4％;specificity,80.0％),the optimal cutoff value of nMDT was 1 169.77 days (sensitivity,81.0％;specificity,76.7％).Conclusions In pulmonary pGGNs,IAC showed significantly shorter VDT and nMDT than MIA/AIS/AAH.When VDT is shorter than 2 095.86 days or nMDT is shorter than 1 169.77 days,IAC is suggested.

Budd-Chiari syndrome (BCS) is characterized by the hepatic outflow obstruction from the small hepatic vein to the superior hepatic inferior vena cava. Portal vein thrombosis (PVT) refers to the development of thrombosis in the main portal vein, with or without thrombosis in the superior mesenteric or splenic vein. A large number of studies have shown that prothrombin (factor II, F2) G20210A mutation is related to BCS and PVT. F2 and its G20210A mutation are introduced, the effect of F2 G20210A mutation on thrombosis is reviewed, and the prevalence of F2 G20210A mutation in China is analyzed. An attempt is made to focus on the association of F2 G20210A mutation with PVT and BCS. It is believed that F2 G20210A mutation to some extent increases the risk for PVT and BCS. However, the prevalence of F2 G20210A mutation is extremely low in the Chinese population. Thus, this mutation may not be regarded as the cause of PVT and BCS in China.

ObjectiveTo explore the attentional biases in male alcohol dependent (AD) patients and the correlations between the attentional bias and alcohol-related factors.MethodsA total of 30 recently detoxified male individuals with alcoholism were compared with 37 healthy controls ( HC ) on the Chinese Emotional Stroop Task using negative,neutral,and alcohol-related words.ResultsThe comparison between AD group( ( 1382.13 ±323.38) ms,( 1365.76 ±313.03)ms,( 1433.20 ±342.23) ms,respectively) and HC group( (797.27 ±216.97)ms,( 794.11 ± 209.41 ) ms,(799.40 ± 215.82 ) ms respectively) on the reaction time of neutral,negative and alcohol-related words were significant ( t =8.822,P ＜ 0.001 ; t =8.922,P ＜ 0.001 ; t =9.234,P ＜ 0.001 ).The error number of of the neutral and negative- related words of the patients ( ( 3.70 ± 2.56) time,( 4.23 ± 2.53 ) time)was worse than that of HC group( ( 2.11 ± 1.87 ) time,( 1.92 ± 1.82 ) time) ( t =2.939,P =0.005 ; t =4.355,P ＜0.01 ).Error number of the alcohol- related words between two groups were not significant;Its alcohol-related words attentional bias negative correlation to the age of initial alcohol use(P＜ 0.05 ),and positive correlation to continue drinking and score of self-rating depression scale (P＜0.05).Age of addiction and the score of self-rating anxiety scale enter the regression equation of alcohol-related words.ConclusionThese results demonstrate that alcoholics have attentional bias in alcohol-related words and reward-related brain regions may be associated with craving among male patients with attentional bias.

Objective:To explore the status of STAT3 phosphorylation in myeloid-derived suppressor cells (MDSCs) of breast cancer and its function in the immunosuppressive effect of MDSCs on proliferation and cytokine secretion of T cells. Methods:CCD33+cells were isolated from healthy umbilical cord, blood-derived, peripheral blood mononuclear cells and were co-cultured with breast cancer cell line MDA-MB-231 in vitro using Transwell plates to induce MDSCs. The untreated CD33+cells were used as con-trols. Idoxuridine (IDO) suppressor expression and STAT3 phosphorylation were examined using Western blot assay. The proliferation and cytokine secretion of T cells, which were co-cultured with MDSCs, were determined by methyl thiazol tetrazolium assay and en-zyme-linked immunosorbent assay. 1-MT and JSI-124 were used to investigate the function of IDO and pSTAT3 in MDSC-mediated T cell immunosuppression. Results:The protein levels of IDO and pSTAT3 in MDSCs were significantly upregulated. MDSCs obviously suppressed T-cell proliferation, which was reversed by 1-MT or JSI-124 (P<0.05). MDSCs could promote TGF-βand IL-10 secretions, but could also remarkably inhibit IFN-γsecretion (P<0.05). After incubation with 1-MT or JSI-124, the increase in TGF-βand IL-10, as well as the decrease in IFN-γ, was significantly reversed. Conclusion:The upregulated pSTAT3 induced the IDO increase in MDSCs. JSI-124 can block MDSC-mediated immunosuppressive effect on T cells in breast cancer.

ObjectiveTo systematically evaluate the efficacy of mirabilite umbilical compress in the treatment of ascites in liver cirrhosis. MethodsThe literature on the treatment of cirrhotic ascites with mirabilite umbilical compress was searched in CNKI, VIP, Wanfang Data, and PubMed databases. A meta-analysis was carried out using the random effect model. The continuous and categorical data were expressed as aas standard mean difference (SMD) and odds ratio (OR), respectively. ResultsA total of 11 randomized controlled trials were included. The mirabilite umbilical compress treatment group showed a significantly higher response rate of ascites (OR=3.19, P＜0.0001) and significantly reduced abdominal circumference (SMD=1.69, P＜0.0001) and body weight (SMD=2.77, P＜0.0001) compared with the control group. After mirabilite umbilical compress treatment, alanine transaminase level was significantly decreased (SMD=1.92, P=00009), albumin level was significantly increased (SMD=-1.78, P=0.0006), while aspartate aminotransferase and total bilirubin levels showed no significant changes (SMD=3.39, P=0.25). ConclusionMirabilite umbilical compress is effective in the treatment of ascites in liver cirrhosis, yet its efficacy in improving liver function remains uncertain.
