OBJECTIVE:To analyze the effect of precision filtration infusion apparatus and other methods on reduction of ADR induced by Acanthopanax injection. METHODS:532 patients receiving intravenous infusion of Acanthopanax injection were randomly divided into observation group and control group;observation group used disposable precision filtration infusion appara-tus,while control group used disposable ordinary infusion apparatus. The occurrence of ADR were compared between 2 groups. RE-SULTS:The incidence of ADR in observation group(2.68%)was significantly lower than in control group(7.75%),with statisti-cal significance(P<0.05). CONCLUSIONS:Intravenous infusion of Acanthopanax injection with disposable precision filtration in-fusion apparatus can effectively reduce the occurrence of ADR.

Background miRNAs are a group of non-coding small RNA molecules,and they play an important role in regulating the apoptosis of LECs.The biological effects and mechanisams of miRNAs on LECs in agerelated cataract still need to be further elucidated.Objective This study was to investigate the anti-oxidative effects of miR-204 on age-related cataract in vitro.Methods The specimens of anterior lens capsules from agerelated cataract patients and normal donors were collected in Shandong Eye Institution and 20 subjects for each.The expression level of miR-204 was detected and compared between cataractous eyes and normol eyes by real-time fluorescence quantitative PCR (RT-qPCR).HLE-B3 cells,a human LEC line,were cultured,and the oxydative stress models of LECs were established by adding 200 μmol/L H2 O2 in the medium.The models were divided into model control group,miR-204 agomir group,agomir negative control group,miR-204 antgomir group and antagomir negative control group according to the difference of tranfected agents,and normal cells served as the control group.Twenty-four hours after transfection,the expression levels of miR-204 mRNA in the cells of various groups were detected by RT-qPCR to varify the transfection rate.Apoptosis rate of the cells was assayed by flow cytometry.The relative expression levels of TP53INP1 mRNA and p53 mRNA as well as their proteins were detected by RT-qPCR and Western blot,respectively.Results The mean expression level of miR-204 was significantly lower in the anterior lens capsules of cataractous eyes than that in the normal eyes (t=14.21,P＜0.05).The mean apoptosis rate of cells was 1.31±0.12,4.90±0.28,2.60±0.15,4.39±0.20,5.74±0.13 and 4.34±0.63 in the normal control group,model control group,miR-204 agomir group,agomir negative control group,miR-204 antgomir group and antagomir negative control group,respectively.The apoptosis rate was significantly increased in the model control group compared with the normal control group (t =-20.69,P＜0.01) and the apoptosis rate was also increased in the miR-204 antagomir group compared with antagomir negative control group (t =3.79,P＜0.05);while the apoptosis rate in the miR-204 agomir group was significantly declined in comparison with agomir negative control group (t=-12.20,P＜0.01).The relative expression levels of TP53INP1 and p53 mRNA and proteins in the cells were significantly higher in the model control group than those in normal control group (mRNA:t =6.44,11.71,both at P＜0.0I;protein:t =10.72,19.40,both at P＜0.01),and so were between the miR-204 antagomir group and antagomir negative control group (mRNA:t =4.07,3.74,both at P＜ 0.05;protein:t =7.18,10.58,both at P＜0.05).However,the expression levels of TP53INP1 and p53 mRNA and protein were significantly reduced in the miR-204 agomir group in comparison with the agomir negative control group (mRNA:t =-19.28,-10.58,both at P＜0.05;protein:t=-6.50,-6.36,both at P＜0.05).Conclusions miR-204 induces oxidative damage of age-related cataract via targeting TP53INP1,which suggests that the activation of TP53INP1-p53 signaling may be involved in the development of age-related cataract.

Aim To investigate the inhibitory effects of xanthotoxol(XT) on neutrophil infiltration and brain edema induced by focal cerebral ischemia-reperfusion injury in rats.Methods Focal cerebral ischemia-reperfusion model in rat was induced by transient occlusion of the middle cerebral artery for 2 hours and followed by 24 hours of reperfusion.XT(2.5,5 and 10 mg?kg-1,ip)was administered at 1 hour and 12 hours after the onset of ischemia,respectively.After 24 hours of reperfusion,the influence of XT on neurological deficit score,brain edema and infarct size were evaluated;the activity of Na+,K+-ATPase,Ca2+-ATPase and myeloperoxidasse(MPO) in the ischemic hemisphere cortex of the middle cerebral artery area was assayed by spectrophotometry;the expression of intercellular adhesion molecule-1(ICAM-1) and E-selectin was measured with immunohistochemistry.Results XT significantly reduced the neurological deficit score,brain edema and infarct size,enhanced activity of Na+,K+-ATPase and Ca2+-ATPas,suppressed the injury-induced upregulation of MPO activity and cell adhesion molecules(ICAM-1 and E-selectin) expression in the brain tissue.Conclusion XT attenuates brain damage following focal cerebral ischemia-reperfusion in rats and its mechanism may partly be due to the inhibition of inflammation and brain edema induced by ischemia-reperfusion.

Objective To explore the prevalence of nonalcoholic fatty liver disease(NAFLD)in patients with polycystic ovary syndrome(PCOS).MethodsA case-control study employing 60 non pregnant patients with PCOS and 60 non-pregnant patients without PCOS as control was conducted to compare the prevalence of NAFLD.Resuits The aminotransferase(ALT),fasting insulin and homeostasis model assessment of insulin resistance(HOMA-IR)levels were(29±15)U/L,(19±12)mU/L and 0.47±0.29 in PCOS group,which were significantly higher(P＜0.05)than corresponding parameters in control group[(15±13)U/L,(11±8)mU/L and 0.31±0.21)].The occurrence of insulin resistance and NAFLD was 63％(38/60)and 42％(25/60),higher than those in control group[35％(21/60)and 20％(12/60),P＜0.05].The increment of ALT was 40％(24/60)in PCOS group,higher than that of 3％(2/60)in control group(P＜0.01).Compared with patients witIlout NAFLD,patients with NAFLD had significantly increased body mass index(P＜0.01),waist-hip ratio,AIJT,C-reaction protein,fasting insulin,insulin and HOMA-IR levels 2 hours after oral glucose tolerance test(P＜0.05).Conchsion The increased prevalence of NAFLD in PCOS patients suggests an association between these two conditions and the necessity of hepatic screening among PCOS patients for potential NAFLD.

Objective To assess value of serum level of ischemia modified albumin (IMA) in diagnosis for myocardial ischemia of coronary artery disease (CAD). Methods Seventy-two patients with clinically suspected myocardial ischemia of CAD admitted to The First People's Hospital of Hangzhou during November 2009 to May 2010 ready for undergoing coronary angiography, the gold standard for diagnosis of CAD, were randomly selected for the study. The patients were divided into CAD and non-CAD groups based on their coronary angiography. Serum level of IMA was determined with cobalt-albumin binding ( ACB) assay before coronary angiography, which served as diagnostic standard for CAD. Logistic regression analysis method was used to evaluate varied levels of IMA with area under the receiver operating characteristic curve (AUCROC) in diagnosis for myocardial ischemia of CAD. Results Mean level of IMA was (97 ±24) U/ml and (81 ±15) U/ml for CAD group (n =51) and non-CAD group (n =21), respectively. Sensitivity and specificity of a cut-off value of IMA 83.69 U/ml in diagnosis for myocardial ischemia of CAD was 80 percent and 57 percent, respectively, with a predictive value of a positive test 82 percent and that of a negative test 55 percent, respectively, from AUCROC. Logistic regression analysis demonstrated that both hypertension (P=0. 022, 6 = 1.421, OR=4. 141) and level of IMA (P=0.003, b= 1.780, OR=5.928) were independent predictors for CAD. Conclusions Sensitivity, specificity and predictive value of a positive test of the level of IMA are relatively high in diagnosis for myocardial ischemia of CAD, which is an independent predictor of it.

Objective To evaluate the long-term safety and efficacy of domestic Firebird rapamycin-eluting stent in treatment of patients with coronary artery disease (CAD). Methods The 465 patients with CAD received percutaneous interventional therapy with domestic Firebird or imported Cypher rapamycin-eluting stent based on patients' will and they were followed up for more than 24 months. Results The 321 cases in Firebird group were followed up for (45.3 ±11.1)months, with 166 cases (51.7%) received reexamination by coronary angiography. The 144 patients in Cypher group were followed up for (46.1 ± 12. 1) months, with 82 patients (56.3%) received reexamination by coronary angiography. At the termination of follow-up, there were no significant differences in all-cause death (7.8% vs. 7.6 %, x2 = 1.32, P = 0. 250), cardiac death (5.9% vs.5.6%, x2 =0. 02, P=0. 877), acute myocardial infarction (2.8% vs. 3.4%, x2 =0. 15, P=0. 697),cardiovascular-cause rehospitalization (29.6% vs. 31.9 %, x2 =0.26, P=0. 610), acute and subacute thrombosis events (0.9% vs. 1.3%, x2 =0.19, P=0.661), late thrombotic events (1.2% vs.1.3%, x2 =0. 02, P=0. 900) and target lesion revascularization (3.4% vs. 4.2%, x2 =0. 15, P=0. 694) between two groups. Conclusions Domestic Firebird rapamycin-eluting stent has the same or similar long-term safety and efficacy with imported Cypher rapamycin-eluting stent.

Cardiopulmonary exercise test and electrocardiogram exercise test were performed in 68 patients with suspected coronary artery disease,the diagnostic value of two tests was compared with coronary angiography results as the gold standard.The results show that the sensitivity,specificity,positive predictive value and negative predictive value of electrocardiogram exercise test for coronary heart disease were 51.28％,68.97％,68.97％ and 51.28％ respectively; those for ratio of O2 pulse peak in cardiopulmonary exercise test were 51.28％,75.86％,74.07％ and 53.66％ respectively.It suggests that the results of cardiopulmonary exercise test may have the same value as electrocardiogram exercise test in diagnosis of coronary artery disease.

Aims The purpose of this study is to investigate thediagnostic value of SWEfor fibrosis in patients with CHBand the factorsinfluencing the accuracy. Methods From July 2013 to October 2015, 261 patients with CHB were recruited from the First Affiliated Hospital of Sun Yat-sen University.All patients received SWE, anthropometry measurement, blood cell count, liver function test and virological indicators measurement. Liver fibrosis was staged from F0 to F4 by METAVIR scorebased onliver biopsy results of 133 CHB patients , while 128 patients were diagnosed as decompensated cirrhosis. Diagnostic accuracyof SWE were evaluated by Receiver Operating Characteristic Curve (ROC) using liver hepatic pathology and decompensated cirrhosis as gold standards. Logistic model was used to find out confounding factors that influence the accuracy of SWE. Results The Area Under ROC (AUC) for liver stiffness measurement with SWE were 0.891, 0.932 and 0.910 for the diagnosis of significant fibrosis (≥ F2), advanced fibrosis (≥F3) and cirrhosis (F4), respectively. A multifactor logistic regression combined modelwas built and showed that hepatic steatosis will decrease the accuracy of SWE. Conclusion SWE could be a valuable method for the noninvasive liver fibrosis assessment. The accuracy of SWE may be influenced by hepatic steatosis.

Objective Atherosclerosis is widely accepted as a chronic inflammatory disease. Serum biomarkers for vulnerable plaques not only serve as diagnostic tools for the identification of patients with acute coro-nary syndrome, but also assist the identification of high-risk patients. However, the existing data are limited and conflicting. In the present study, we determined whether the plasma levels of interleukin-1β (IL-1β) are correlated with adverse cardiac outcomes in patients with ST-evaluate acute myocardial infarction (STEAMI) undergoing pri-mary percutaneous coronary intervention (PCI). Effect of the plasma intedeukin-1β level on prognosis of patients with ST-segment elevation acute myocardial infarction. Method This prospective single-center study included 96 patients with SIEAMI with onset < 12 h who underwent primary PCI, 271 patients with stable angina pectoris (SAP) and 148 control subjects without coronary artery disease who were consecutively admitted to hospital be-tween Mar, 2006 and Mar, 2008. Plasma IL-1β levels were measured by enzyme-linked immunosorbent assay in all subjects. The patients with STEAMI were then followed prospectively for the occurrence of major adverse car-diac events (MACE) (including cardiovascular death, non-fatal myocardial infarction, heart failure, and cardio-genie shock) during hospitalization. We determined the association between IL-1β levels with the risk of MACE using multivariate logistic regression. Results Compared with the SAP patients and control subjects, patients with STEAMI had higher levels of IL-1β (P < 0.05). During hospitalization, 32 patients (33.3%) experienced MACE [23 males, 9 females; age: (75.44±13.45) years]. In the STEAMI patients, IL-1β was elevated in patients with MACE compared with patients without MACE (median [range]: 26.52 [12.010 to 155.244] pg/mL vs 2.157 [0.433 to 83.021] pg/mL; P < 0.01) by non-parameter analysis. Significant and positive correlations be-tween IL-1β and cardiac troponin-I (cTnI) (r = 0.353, P =0.004) were observed by Spearman's correlations analysis. Multivariate logistic regression analysis revealed that IL-1β levels ≥20 pg/mL were significantly and in-dependently associated with MACE during hospitalization (odds ratio: 32.05; 95% confidence interval: 4.28 to 240.151; P =0.001). Conclusions The present study revealed that patients with STEAMI had elevated IL-1β levels on admission. The plasma IL- 1β level is an independent inflammatory predictor for in-hospital MACE in pa-tients with STEAMI undergoing percutaneous coronary intervention.

Hepatorenal syndrome (HRS) is one of the common serious complications in patients with end-stage liver disease and has poor prognosis and high mortality, and in-depth studies on its pathogenesis will help to achieve precise prevention and treatment. Although the exact pathogenesis of HRS has not yet been fully elucidated, achievements have been made in the pathogenesis of HRS. The classic mechanism of the hypothesis of visceral vasodilation continues to be enriched and perfected, and new understandings have been gained for the role of systemic inflammation and intestinal bacterial translocation in pathogenesis. In addition, a new concept of cardiorenal syndrome is put forward for the involvement of cardiac dysfunction in HRS, and renal pathology has been questioned and challenged. This article reviews the research advances in the pathogenesis of HRS in recent years and related implications for clinical work.
