Objective To know the prevalence rate of hypertension and the rates of illness-awareness,medication and blood pressure control in Wenzhou. Method With random cluster sampling,1 034 residents aged≥15 yrs were selected from the communities of Wenzhou,and investigated with the standard questionnaires. Results The prevalence rate of hypertension in Wenzhou was 38.97% and the standardized rate was 22.27%. Among the patients with hypertension,51.12% of them were aware,and only 40.69% of them took medication and 9.18% of them had their blood pressure controlled. Conclusion The prevalent rate of hypertension is higher,but the awareness rate,medication rate and controlling rate are lower in Wenzhou city. The comprehensive interventions are needed for the prevention and treatment of hypertension.

Objective To evaluate the effect of pronase on amoxicillin and metronidazole concentrations in gastric tissue. Methods C57BL/6 mice were randomly divided into experimental group ( n = 70 ) and control group ( n = 70 ) . Amoxicillin ( 28. 6 mg/kg ) , metronidazole ( 22. 5 mg/kg) and omeprazole (138.2 mg/kg) were administered orally to C57BL/6 mice, combined with pronase (110 mg/kg) or same amount of sterile PBS. Gastric tissue and blood plasma samples were taken at 10 point-in time (7 mice/time) from 15 min up to 360 min after administration. Concentrations of amoxicillin and metronidazole were detected by high performance liquid chromatography. Gastritis index of gastric mucosa ( hematoxylin-eosin staining) and the gastric tissue expressions of mucin 5 AC (Western blot) were detected at 120 min and 360 min after administration. Results The time to peak concentration of amoxicillin and metronidazole in gastric tissue appeared earlier than that in blood plasma (15 min vs 60 min). Tissue concentrations of amoxicillin and metronidazole of experimental group were significantly higher than those of control, and they were mainly at 15 min to 90 min (P ＜0. 05). Plasma concentrations of amoxicillin and metronidazole of experimental group at 15 min and 30 min were higher than those of control ( P ＜ 0. 05 ). There was no difference in gastritis index between experimental group and control at 120 min and 360 min after administration (0.28±0. 18 vs 0. 14 ±0. 14,P＞0.05; 0. 43 ±0. 20 vs 0. 28 ±0. 18,P ＞0. 05). The expressions of mucin 5 AC in experimental group were lower than those of control ( 0. 036 ± 0. 006 vs 0. 197 ± 0. 058; P ＜0. 05; 0. 039 ± 0. 008 vs 0. 208 ± 0. 072, P ＜ 0. 05 ). Conclusions Pronase can significantly enhance the drugs penetration from mucus into gastric tissue. Concentrations of amoxicillin and metronidazole of experimental group in local gastric tissue and plasma are higher than those of control, especially in improving concentrations of gastric tissue and prolongation of exposed time.

Objective To investigate the value of dynamic contrast?enhanced MRI (DCE?MRI) in the differential diagnosis of glioblastoma and brain metastases. Methods Twenty patients with high grade gliomas and 20 cases patients with brain metastases proved by surgery and pathology were collected, and patients were examined with conventional MRI and DCE?MRI preoperatively. The ROIs were manually placed in solid parts of the tumors and their surrounding tissues to calculate Ktrans, Kep and Ve values. The Ktrans, Kep and Ve values differences for the solid part and surrounding tissues of the two brain tumors were compared by two independent sample t test. The correlation between Ktrans of the solid parts of the two brain tumors and Ktrans, Kep and Ve values of their surrounding tissues were studied by Pearson correlation analysis. Results The Ktrans, Kep and Ve values of glioblastoma were(0.258 ± 0.063)min-1,(0.398 ± 0.082)min-1, 0.632±0.084, the Ktrans, Kep and Ve values of brain metastases were(0.233±0.053)min-1,(0.357±0.042)min-1, 0.672±0.113. There were no significant differences between the glioblastoma and brain metastases for Ktrans, Kep and Ve values(t=-1.354,-1.982, 1.276, all P>0.05). The Ktrans, Kep and Ve values of surrounding tissues of glioblastoma were(0.093±0.032)min-1,(0.411±0.089)min-1, 0.107±0.021, the Ktrans, Kep and Ve values of surrounding tissues of brain metastases were(0.033±0.010)min-1,(0.204±0.045)min-1, 0.069±0.017. The Ktrans, Kep and Ve values of surrounding tissues between glioblastoma and brain metastases had significant difference (t=-7.978,-9.303,-6.203, all P<0.05). The Ktrans of glioblastoma were correlated with Ktrans, Kep and Ve values of their surrounding tissues (r=0.759, 0.464, 0.651, all P<0.05); The Ktrans values of brain metastases had no relationship with Ktrans, Kep and Ve values of their surrounding tissues (P>0.05). Conclusion The DCE?MRI can quantitatively display the microvascular permeability and accurately evaluate the damage of blood?brain barrier of glioblastoma and brain metastases, which has an important value in studying biological characteristics and differential diagnosis of the two brain tumors.

Background Fungal keratitis has poor prognosis and high blinding rate,so it is vital to identify the risk factors that affect the treating outcome and prognosis of fungal keratitis.Objective This study was to evaluate the clinical outcome of fungal keratitis and identify the affecting factors.Methods This was a series cases-observational study.A total of 267 eyes of 267 patients with fungal keratitis were included in Henan Eye Institute during January 2013 to January 2014.Eye examinations were performed including slit-lamp microscope examination,corneal smears,confocal microscopy,fungal culture and identification.Combined anti-fungal drugs were topically used in all eyes for the initial treatment then the treating regimen were selected based on the susceptibility testing.corneal lesion resection combined with conjunctival flap transplantation,lamellar corneal transplantation or penetrating corneal transplantation was performed respectively on the patients with poor curative effect after drug treatment.The clinical prognosis of the patients was graded and the affecting factors for clinical outcome were evaluated.This study protocol complied with Helsinki Declaration and was approved by Ethic Committee of Henan Eye Hospital.Written informed consent was obtained from patients or guardians.Results One hundred and eighty-five eyes were cured by anti-fungal eye drops with the effective rate of 69.29％,and the inflammation was controlled in 60 eyes who received combination procedure of anti-fungal drugs with different surgeries,while 22 eyes lost visual function because of refractory glaucoma and final evisceration.The total clinical effective rate was 91.76％.Aspergillus and Fusarium spp.appeared to be the most common pathogenic fungi by drug sensitivity test.The keratitis caused by Aspergillus had lowest cure rate among different fungi (x2 =11.350,P =0.002) and the most poor clinical prognosis (H=31.285,P =0.013).The medication curative rate was 71.8％ in the patients with positive culture outcome,which was higher than 62.5％ in the patients with negative culture outcome (x2=8.75,P＜0.01).A significant difference was found in the medication curative rate and prognosis between the patients with ≥ 2 kinds of sensitive anti-fungal drugs and the patients with ＜2 kinds of sensitive anti-fungal drugs (77.5％ versus 52.3％,x2 =9.63,P＜0.01;H=24.281,P =0.021).Size of infiltration area,with or without hypopyon,number of sensitive drugs,and pathogenic fungi were significantly correlated with clinical outcome (all at P ＜ 0.05).Conclusions In vitro susceptibility testing can guide clinical drug treatment of fungal keratitis.Infiltration area ＞ 16 mm2,hypopyon ＞2 mm,resistance to those drugs in vitro and infection of Fusarium.spp or Aspergillus.spp are predictors of a poor outcome.

Objective To investigate the potential mechanism for symptoms related to epigastric discomfort in patients without Helicobacter pylori (H.pylori) infection.Methods Patients who underwent gastric endoscopy and conformed H.pylori negative by histologic examination were enrolled.Among them,232 adult patients were collected between August 2006 and November 2006 and 31 children were collected between September 2005 and August 2009.All patients showed no apparent abnormality by endoscopic examination.The endoscopic biopsy was examined with HE or Warthin-Starry staining.Results In adult group,arteriole obstruction was found in 16 (8.8%) cases and focal haemorrhage in 82 (45.6%) cases.Both were existed in 82 (45.6%) cases.The histopathologic findings showed that arteriole obstruction in transition zone (65.2 %,P = 0.159) was common,whereas the focal haemorrhage in gastric fundus and corpus (65.6%,P=0.001) was in predominance.The symptom of heartburn was less in patients with arteriole obstruction and/or focal haemorrhage in comparison with those without these changes (x2 =8.564,P=0.003).In adolescent group,arteriole obstruction and/or focal haemorrhage accounted for 96.8% (30/31).Conclusion Gastric mucosa ischemic resulted from arteriole obstruction are commonly seen in both adult and adolescent patients,which is an important reason for epigastric discomfort in H.pylori negative patients.

Objective:To observe the protective effect of deproteinized extract of calf blood (DECB)on the ethanol-induced liver injury of the mice,and to preliminaryly discuss its mechanism. Methods:Sixty healthy ICR mice were divided into control group,model group,positive drug group,low,medium and high doses of DECB groups (n=10).By intragastric administration,the mice in control group were given 20 mL·kg-1 saline solution, the mice in low,medium and high doses of DECB groups were administrated with 0.125,0.250,0.500 g·kg -1 DECB,and the mice in positive drug group were administrated with 0.63 g·kg -1 Hugan Tablets;once a day for 30 d. 1 h after the last administration,except control group,the mice in other groups were administrated with one-time grant of 50% ethanol 14 mL·kg -1 ,and fasted for 16 h to establish the models of acute alcohol liver injury.The endurance alcohol time and drunk time of the mice were determined,the activities of aspartate aminotransferase (ALT)and alanine transaminase (AST)activity in serum of the mice were detected,the levels of triglyceride (TG),glutathione (GSH)and malonic dialdehyde (MDA)in liver tissue were determined,and the pathological changes of liver tissue were detected.Results:Compared with model group,the drunk symptoms of the mice in different doses of DECB groups were obviously reduced,the endurance time of the mice in high dose of DECB group and positive drug group was prolonged (P <0.05),and the drinking time was shortened (P <0.05);the ALT and AST activities in serum in mediun and high doses of DECB groups were significantly lower than those in model group (P <0.05).Compared with model group,the MDA and TG levels in liver tissue of the mice in medium and high doses of DECB groups and positive drug group were obviously reduced,and the GSH levels were increased (P <0.05);compared with model group,the pathological damages of liver tissue of the mice in high dose of DECB group caused by ethanol were significantly reduced.Conclusion:DECB can improve ethanol-induced liver injury which may be related to the inhibition of hepatic oxidative stress response.

To explore the effect of IL-33 on various tumor types,exogenous injection of recombinant mouse IL-33 protein (mIL-33) was used to study the efficacy of different subcutaneous tumor-bearing mouse models. In this study,mIL-33 has been found to significantly inhibit the growth of liver,lung,gastric,prostate,and colon cancers. However,the inhibition of tumor growth by mIL-33 was not completely consistent in different types of tumor. A lower dose of mIL-33 (10 μg/kg) significantly inhibited tumor growth in subcutaneous tumor-bearing mice of liver,lung,and gastric cancers,while a higher dose of mIL-33 (90 μg/kg) was required to exert the corresponding antitumor effect in subcutaneous tumor-bearing mouse models with prostate and colon cancers. In addition,the growth inhibitory effect of mIL-33 on subcutaneous tumors of colon cancer was also correlated with the duration of administration and the stage of tumor progression. The results of this study indicate that mIL-33 significantly inhibits the growth of a variety of tumors,suggesting that IL-33 might be an effective target for tumor treatment.

Objective: To evaluate the long-term efficacy of a second generation biodegradable polymer sirolimus-eluting stent (EXCEL2) in treating patients with de novo coronary artery diseases. Methods: CREDIT Ⅱ trial was a prospective, multicenter, randomized, controlled study, conducted at 15 Chinese cardiac centres from November 2013 to December 2014. In this analysis, eligible patients for coronary stenting (n=419) were randomized to receive either the EXCEL2 stent (n=208) or the EXCEL stent (n=211). The primary endpoint was target lesion failure (TLF) at 3 years after PCI defined as a composite endpoints of cardiac death, target vessel myocardial infarction (TVMI), or clinically indicated target lesion revascularization (CI-TLR). Secondary endpoints included patient-oriented composite endpoint (PoCE) including all-cause death, all MI, or any revascularization at 3 years and independent components, and stent thrombosis according to Academic Research Consortium′s (ARC) definition. Results: Among 419 enrolled patients, 413 (98.6%) patients completed 3-year clinical follow-up. Compared with the EXCEL group, 3-year TLF (5.4%(11/204) vs. 11.5% (24/209), P=0.025) and PoCE (9.8% (20/204) vs. 20.1% (42/209), P=0.003) were significantly lower in the EXCEL2 group. The cumulative event rate of CI-TLR (2.0% (4/204) vs. 5.7% (12/209), P=0.042) and any revascularization (4.9% (10/204) vs. 14.4% (30/209), P=0.001) were statistically lower in the EXCEL2 group than in the EXCEL group. There were no significant difference between two groups in terms of all-cause death and all MI. Rates of stent thrombosis were low without significant difference between the two groups (EXCEL2 vs. EXCEL, 1.0% (2/204) vs. 2.9% (6/209), P=0.285). Conclusion 3-year clinical follow-up results demonstrate that EXCEL2 stents are effective and safe in treating CAD patients with de novo coronary lesions.

Objective: To explore the value of SYNTAX revascularization index (SRI) on evaluating the long-term prognosis of coronary artery disease (CAD) patients implanted with biodegradable polymer drug-eluting stents (BP-DES) and define the best threshold of SRI for predicting all-cause mortality in these patients. Methods: Data used in this study derived from the I-LOVE-IT 2 trial (evaluate safety and effectiveness of the Tivoli DES and the Firebird DES for treatment of coronary). I-LOVE-IT 2 trial was a prospective, multicenter, randomized, assessor-blinded, non-inferiority study. A total of 1 829 patients implanted with BP-DES were divided into 3 groups, namely SRI=100% group (n=963), 50%≤SRI<100% group (n=527) and SRI<50% group (n=339). The primary endpoint was 48-month patient-oriented composite endpoint (PoCE), a composite of all-cause mortality, myocardial infarction(MI), stroke, and/or any revascularization. The secondary endpoints were components of PoCE and definite/probable stent thrombosis at 48 months. The receiver operating characteristic curve was used to investigate the best cut-off point of SRI for 48-month all-cause mortality. The Cox regression analysis was used to identify independent predictors of the all-cause death and PoCE at 48 months. Results: Incidence of PoCE at 48 months was significantly lower in SRI=100% group than patients with 50%≤SRI<100%(17.34% (167/963) vs. 22.20% (117/527), P<0.05) and SRI<50% (17.34% (167/963) vs. 24.78% (84/339), P<0.05). Comparing with SRI=100% group, the patients with 50%≤SRI<100% suffered higher rates of all MI (7.78% (41/527) vs. 4.26% (41/963), P<0.05) and target vessel MI (6.45% (34/527) vs. 4.26% (41/963), P<0.05); patients with SRI<50% had higher rates of all-cause mortality (5.90% (20/339) vs. 3.12% (30/963), P<0.05) and any revascularization (14.16% (48/339) vs. 3.12% (30/963), P<0.05). The receiver operating characteristic curve analysis showed that the SRI=65% was the best cut-off point to predict the all-cause mortality at 48 months (area under the curve was 0.58, sensitive was 0.47, specificity was 0.70). Meanwhile, SRI<65% was an independent predictor of 48-month all-cause mortality (HR=2.06, 95%CI 1.25-3.38) and PoCE (HR=1.34, 95%CI 1.09-1.66). Conclusions SRI serves as a good index for predicting long-term prognosis and SRI<65% is an independent predictor of 48-month PoCE and all-cause mortality for CAD patients with BP-DES implantation. Meanwhile, SRI≥65% might be a reasonable threshold of incomplete revascularization.
