Objective To explore the effect of candesartan combined with levamlodipine besylate on hypertension and target organ protection.Methods One hundred and twenty-two patients with hypertension and proteinuria from February 2011 to July 2013 were divided into observation group (61 cases) and control group (61 cases) by random number table method.Patients in both groups were given oral candesartan 8 mg/d,and the observation group was treated with levamlodipine besylate 2.5 mg/d on this basis.Six months after treatment,the blood pressure levels,carotid intima-media thickness (IMT),interventricular septum thickness (IVST),left ventricular posterior wall thickness (LVPWT),left ventricular end diastolic diameter (LVEDD),left ventricular mass index (LVMI) and renal function between 2 groups were observed.Results After 6 months of treatment,the total effective rate in observation group was 86.9％ (53/61),and in control group was 72.1％ (44/61),there was significant difference (P ＜ 0.05).Systolic blood pressure and diastolic blood pressure levels in two groups after treatment were decreased,in observation group which were lower than those in control group,and there was significant difference (P ＜ 0.05).IVST,LVEDD,LVPWT,LVMI and carotid IMT in 2 groups after treatment was lower than that before treatment,in observation group which was obviously lower than that in control group [(8.5 ± 1.3) mm vs.(9.2 ± 1.2) mm,(39.6 ± 4.8)mm vs.(44.3 ± 3.9) mm,(8.4 ± 1.4) mm vs.(9.1 ± 1.3) mm,(89.4 ± 9.3) g/m2 vs.(97.3 ± 8.9) g/m2,(8.3 ± 0.3) mm vs.(8.7 ± 0.5) mm],and there were significant differences (P ＜ 0.05).Urea nitrogen between 2 groups before and after treatment had no significant difference(P ＞ 0.05).The serum creatinine,creatinine clearance rate,total 24 h urinary albumin and microalbuminuria in 2 groups was significandy improved compared with that before treatment,and in observation group after treatment was obviously improved compared with that in control group [(94.6 ±25.5) μmol/L vs.(118.5 ±38.4) μmol/L,(102 ±24) ml/min vs.(96 ± 18) ml/min,(1.05 ± 0.51) mg/24 h vs.(1.27 ± 0.22) mg/24 h,(155 ± 36) mg/L vs.(185 ± 41) mg/L],there were significant differences (P ＜ 0.05).Conclusions The effect of candesartan combined with levamlodipine besylate in treatment of hypertension and proteinuria is better than monotherapy.Combination therapy in reversing left ventricular,improving carotid IMT,protecting kidney function and reducing proteinuria has significant effect,and has no obvious adverse reactions.It is worthy of clinical application.

Objective To appraise therapeutic effects of tubeimoside on herpes simplex keratitis of rabbits. Methods HSV-1 (SM_(44) strain) is recovered on monolayers of BHK-21 cell cultures, then rabbit model of HSK was established after inoculation. After 0.2g/L Tu topically given, all eyes are examined by using slit-lamp-microscopy, and corneal samples were observed for ocular changes under transmission and scanning electromicroscope. (Results )Differences were significant in the three groups of corneal involvement scores. 0.2g/L Tu can obviously reduce corneal involvement area, and can also help to rehabilitate affected corneal epithelial cells. Conclusion Tu agent is able to cure experimental HSK to a certain degree, however, is less effective on HSK than acyclovir.

Objective To analyse the reasons for patients′long PICU stay and to discuss how to de-crease their PICU stay length and optimize medical resource utilization.The another objective is to identify these patients′long-term outcome.Methods We retrospectively analysed the basic information of patients who stayed in our PICU more than 30 days during January 1,2013 to July 31,2014,including pediatric criti-cal illness score on admission,primary diseases and outcome on discharge,in order to determine main reasons for their long PICU stay.Follow-up prognosis was made by Paediatric Overall Performance Category.We used SPSS 19.0 to do data analysis.Results Sixty-seven patients enrolled in this study included 43 boys and 24 girls,49.2%of whom came from emergency department.The median age was 24 months(IQR 8,108), while median length of PICU stay was 39 days(IQR 31,49).Mean pediatric critical illness score on admi-ssion was 78.39 ±9.57.Mean hospital fees was(144 071.74 ±76 944.74)Yuan.Thirty(44.8%)patients did not have any medical insurance.Top three primary diseases were respiratory disease(30 cases),neurolog-ical disease(8 cases)and systemic infection(6 cases).Top three underlying diseases were tracheostenosis or bronchopulmonary dysplasia(6 cases),congenital heart disease(5 cases)and immunodeficiencies(4 cases). Top three complications were respiratory failure(30 cases),multiple organ dysfunction or failure(16 cases), shock(9 cases).Top three reasons for longer PICU stay were weaning off mechanical ventilation difficulty (29 cases),department or hospital transference difficulty(20 cases),feeding difficulty(16 cases).Fifty-four patients were discharged with better health condition,10 patients were auto-discharge.The mortality at dis-charge,1 month after discharge,3 months after discharge and 6 months after discharge were 4.5%,20.9%, 25.4% and 25.4%,respectively.Total 36(53.7%)patients had a good or mildly abnormal Paediatric Over-all Performame Category score(1-2 points)at 6 months after discharge.Conclusion Sequential noninvasive ventilation,timely tracheotomy,timely patients′transference to general ward,development of family ward and rehabilitation wards,appropriate nutrition delivery,regularly difficult disease consultation,reduction of hospi-tal infection and complications may do contribution to shorten these patients′length of PICU stay.Children who survive longer than 3 months after discharge have better long-term prognosis.

ObjectiveTo evaluate the value of microsurgery for acoustic neuromas.MethodsThe author performed a retrospective study of 63 consecutive patients after vestibular schwannomas (VSs) microsurgery with the retrosigoid approaches. The tumor was debulked firstly and dissected from surrounding neural and vascular structures by gripping the tumor capsule,and then drilled of the IAC.Intraoperative electrophysiological monitoring of facial nerve function during operation.Results Total tumor resection was achieved in 52 cases, subtotal resection was achieved in 11 cases. The anatomic preservation of facial nerve was achieved in 58 cases,the acoustic nerve was preserved anatomically in 29 cases.Fifty-eight cases received a follow-up, the mean follow-up time was 7.2 years. Two recurrent patients were found and there were no operative deaths. A long term facial nerve status:twenty-three cases were in grade Ⅰ, twenty-nine cases in grade Ⅱ ,five cases in grade Ⅲ , one cases in grade Ⅳ.Hearing level had an improvement in 9 cases and remained unchanged in 8 cases.ConclusionMicrosurgery treatment is the main choice of the treatment of VSs, could achieve better result in control of tumor and facial and acoustic nerve function restoration.

Objective To explore the role and relationship of N-terminal pro-brain natriuretic peptide (NT-proBNP) and matrix metalloproteinase-9 (MMP-9 ) in risk stratification and prognosis assessment of non-ST elevation acute coronary syndrome (NSTE-ACS).Methods We recruited 114 patients with NSTE-ACS and classified them into three groups according to the GRACE risk stratification:high-risk,intermediate-risk and low-risk groups.Another 5 8 patients were recruited as controls.Arterial blood was collected before angiography for the measurement of serum NT-proBNP and MMP-9 .Gensini score was used to evaluate the degree of coronary artery stenosis.All the patients were followed up for 6 months and MACE was observed and recorded.Results ① The levels of lg NT-proBNP and MMP-9 significantly differed between the groups (P<0.05).② ROC curve analysis showed that lg NT-proBNP could predict MACE of NSTE-ACS;area under the curve was 0.795,the cutoff value was 2 .0 6 9 ,corresponding to the NT-proBNP value of 1 1 6 .5 6 ng/L.MMP-9 could predict MACE of NSTE-ACS;area under the curve was 0 .6 9 6 ,the cutoff value was 3 2 .4 9 ng/ml;both of the abnormal indexes could predict MACE with the sensitivity of 80.41%,specificity of 82.19%,and Youden’s index of 0.63.③ Cox regression analysis showed that abnormal MMP-9 and NT-proBNP levels were independently related to the incidence of MACE by the value of OR as 3.751.Conclusion MMP-9 and NT-proBNP may be used as serological indicators in risk stratification of NSTE-ACS. The combined use of NT-proBNP and MMP-9 increases the power of predicting MACE.

Objective To investigate the relationship of fasting serum FFA composition with central obesity, hypertension, insulin resistance, levels of serum zinc and age, gender-related differences. Methods Serum FFA were determined by high performance liquid chromatogram in 232 commuity|based subjects aged between 35 and 55 years: 109 hypertensives, 123 normotensives. Results Multivariate stepwise linear regression models and correlation analysis showed that serum FFA composition (including levels of n3PUFA, P/S ratio, C20:5/C18:3, C22:6/C20:5 and C20:4/C18:2 ratio) were linearly correlated with waist/ hip ratio, insulin sensitivity index, levels of serum zinc and related to the habit of diet (all P

Objective To quantitatively assess the cardiopulmonary exercise function of spinal cord injury (SCI) patients and observe the effect of aerobic exercise on cardiopulmonary function, motor function and activities of daily living. Methods From December, 2014 to June, 2016, 34 incomplete SCI patients (ASIA C and D) and 23 healthy controls received cardiopulmonary exercise test (CPET). SCI pa-tients were randomly divided into conventional rehabilitation group (n=17) and aerobic exercise group (n=17). The aerobic exercise group received aerobic exercise for four weeks. They were assessed with CPET, motor and sensory function, walking index for spinal cord injury II (WISCI II) and spinal cord independence measure (SCIM) before and four weeks after training. Results Oxygen uptake (VO2)peak, anaerobic threshold (AT), metabolic equivalent of energy (METpeak), VO2/heart rate (HR)peak, respiratory exchange rate (RER)peak, minute ventilation (VE)peak, work rate (WR)peak and systolic blood pressure (SBP)peak were lower in the patients than in the controls (t>2.714, P<0.05). VO2peak、AT、METpeak、VO2/HRpeak、WRpeak increased in the aerobic exercise group after training (t>2.431, P<0.05). METpeak and WRpeak improved in the conventional rehabilitation group after training (t>3.282, P<0.01). The scores of motor in ASIA and SCIM improved in both groups after training (t>2.985, P<0.05). Conclusion The cardiopulmonary function decreased in incomplete SCI patients, which could be improved by moderate intensity aerobic exercise.

Objective To investigate the relation between 25-hydroxyvitamin D3[25(OH)D3] and coronary artery disease. Methods Three hundred and ten patients with selective coronary angiogram (CAG) were enrolled in this study and they were divided into two groups: non-coronary artery stenosis group with 76 patients and coronary artery stenosis group with 234 patients. The degree of coronary artery stenosis was evaluated by the international general Gensini integration system. The levels of fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) were detected by automatic biochemistry analyzer. The level of 25(OH)D3 was detected by tandem mass spectrometry. The relationship of Gensini integration scores and risk factors were analyzed. Logistic regression analysis was used in multicity factors analysis. Results The levels of age, Gensini integration scores, 25(OH)D3, FPG and LDL-C in non-coronary artery stenosis group and coronary artery stenosis group had significant differences (P<0.05). The number of coronary stenosis and Gensini integration scores in 25(OH) D3 deficiency group were significantly higher than those in non-25 (OH)D3 deficiency group (P<0.01). Logistic regression analysis showed that age, FPG and 25(OH)D3 levels were risk factors for coronary artery stenosis (P<0.01 or<0.05), and the level of 25(OH)D3 had negative correlation with coronary artery stenosis (B =- 0.100), and it was a protection factor (OR =0.904, 95%CI:0.911-0.983, P=0.000). Conclusions 25(OH)D3 deficiency is one of the risk factor of coronary artery disease.

Objective To investigate the clinical significance of soluble CD40 ligand (sCD40L ) and lipoprotein associated phospholipase A2 (Lp-PLA2 ) in the assessment of coronary artery severity and risk classification in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).Methods Of the 9 6 patients with coronary heart disease diagnosed by coronary angiography,2 8 patients had stable angina pectoris (SAP),38 patients unstable angina pectoris (UAP)and 30 patients acute non-ST-segment elevation myocardial infarction (NSTEMI).Another 30 patients with non-coronary heart disease (NC)served as controls.The sCD40L and Lp-PLA2 levels were determined by enzyme-linked immune sorbent assay (ELISA)method.The Gensini score was used to assess the severity of coronary artery and analyze the correlation with sCD40L and Lp-PLA2.The correlation of sCD40L and Lp-PLA2 with GRACE risk score was analyzed too.Results ① sCD40L was significantly higher in NSTEMI and UAP groups than in SAP and NC groups (P<0 .0 5 ),but there was no significant difference between NSTEMI and UAP groups (P>0 .0 5 )or SAP and NC groups (P>0 .0 5 ).Lp-PLA2 was significantly higher in NSTEMI group than in UAP,SAP and NC groups (P<0.05).Lp-PLA2 was significantly higher in UAP group than in SAP and NC groups (P<0.05).② We found that sCD40L had obvious correlation with Lp-PLA2 (r=0.284, P<0.01),Gensini score (r=0.213,P<0.05),and GRACE (r=0.224,P<0.05).Lp-PLA2 was significantly correlated with Gensini score (r=0.270,P<0.05),and GRACE (r=0.323,P<0.01).③ Multivariate logistic regression analysis showed that Lp-PLA2 was independently associated with NSTE-ACS (P<0.05).Conclusion The sCD40L and Lp-PLA2 which were significantly elevated in NSTE-ACS are correlated with the severity of coronary artery disease.The two indexes indicate the instability of atherosclerotic plaque;thus they can be used as predictors of risk assessment in coronary heart disease.

Objective To study the relationship of the plasma levels of miRNA-491-5p in Han population in Shaanxi Province and the changes of single nucleotide polymorphisms (SNP ) of the target gene matrix metalloproteinases-9 (MMP-9 ) of miRNA-4 9 1-5 p (has-miR-4 9 1-5 p ) with the incidence risk and prognosis of premature coronary artery disease (pCAD)through the case-control design.Methods In this study,we made a consecutive recruitment of 270 pCAD cases in the case group and 300 cases in the control group.Using the polymorphism method of polymerase chain reaction and restriction fragment length (PCR-RFLP),target gene MMP-9 of has-miR-491-5p and rs1056628 genotypes was detected to compare the association between the variant genotypes and pCAD.Results In the changes of rs1056628C-A polymorphisms,compared with that of CC genotypes (the incidence was 42%),the risks of having coronary heart disease in the individuals carrying CA and AA genotypes were 31%,the difference was statistically significant (P=0.045).The risks of developing coronary heart disease in the individuals carrying CA and AA genotypes were reduced more significantly in the population with low total cholesterol (TC),and low low-density lipoprotein cholesterol (LDL-C).Conclusion Target gene MMP-9 of has-miRNA-491-5p rs1056628C-A polymorphism is associated with the reduced incidence risk of pCAD,and carrying C alleles is an independent risk factor for pCAD.
