OBJECTIVE:To observe the clinical efficacy and safety of Kudiezi injection combined with alprostadil in the treat-ment of posterior circulation ischemic vertigo. METHODS:Totally 180 patients with posterior circulation ischemia were randomly divided into group A,group B and group C. All patients were given aspirin,atorvastatin,nutrition nerve,antihypertensive,hypo-glycemic and other conventional treatment. On this basis,group A was given Alprostadil injection 10 μg,adding into 0.9% Sodium chloride injection 100 ml,iv,once a day;Kudiezi injection 30 ml,adding into 0.9% Sodium chloride injection 250 ml,iv,once a day. Group B was given Alprostadil injection(the same usage as group A);group C was given Kudiezi injection(the same usage as group A). The course was 14 d. The clinic data was observed,including clinical efficacy;blood flow velocity in left vertebral ar-tery(LVA),blood flow velocity in right vertebral artery(RVA),blood flow velocity of basilar artery(BA),changes of peak laten-cy(PL)and incubation period latency(IPL)before and after treatment;and the incidence of adverse reactions. RESULTS:The to-tal effective rate in group A was significantly higher than group B and C,with significant difference(P<0.05). After treatment,the blood flow velocity of LVA,RVA and BA in each group were significantly higher than before,group A was higher than group B and C;PL-Ⅰ,PL-Ⅲ,PL-Ⅴ,IPL-Ⅰ-Ⅲ and IPL-Ⅲ-Ⅴ were significantly lower than before,group A was lower than group B and C,with significant differences(P<0.05);however,there were no significant difference between group B and C(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Kudiezi injection combined with alprostadil has better effica-cy than only Kudiezi injection or alprostadil in the treatment of posterior circulation ischemic vertigo,with good safety.

Clinical Information System(CIS)is a new period of hospital information system(HIS).The construction of CIS can improve doctors and nurses' work.The traditional CIS includes doctor-workstation,PACS,LIS,RIS,etc.By establishing clinical coding system,PASS,online information gathering system and PDA,the information quality and application level of CIS can be elevated.

Aim To investigate the effects of valsartan on activation of signal transducers and activators of transcription 1,3 in glomerular mesangial cells(GMCs) under high concentration of glucose.Methods we used high concentration glucose and valsartan to stimulate the cultured rat GMCs in vitro.The protein expressions of signal transducer and activatior of transcription 1,3(STAT1,STAT3),p-STAT1 and p-STAT3 were observed by Western blot.The protein synthesis of TGF-?_1,fibronectin and type IV collagen in the supernatants of the GMCs were detected by enzyme-linked immunoadsorbent assay(ELISA) and radioimmunoassay.TGF-?_1 mRNA was measured by reverse transcription and polymerase chain reaction(RT-PCR).Results Compared with low glucose control group,the expressions of p-STAT1,p-STAT3 and TGF?_1 mRNA were significantly increased in GMCs under high concentration glucose medium and there observed the high concentration of TGF-?_1,fibronectin and type IV collagen in the supernatants.The expression levels of p-STAT1,p-STAT3 and TGF-?_1 mRNA were significantly lower in the valsartan group than in those the high concentration glucose group.The concentration of TGF-?_1,fibronectin and type IV collagen in the supernatants in the valsartan group were lower than that in the high concentration glucose control group.Conclusion Valsartan can inhibit overproduction of TGF-?_1 and ECM proteins in GMCs under high concentration of glucose,partly by regulating the phosphorylation of STAT1 and STAT3.

ObjectiveTo explore the relationship between chronic kidney disease (CKD) and cerebral small vessel disease (SVD) in elderly patients. MethodsOne hundred and fifty-two elderly male CKD patients for experimental group and 158 elderly male for control group were recruited. Demographic data and vascular risk factors were recorded. White matter lesion (WML) was semi-quantitatively assessed by cerebral magnetic resonance imaging (MRI), and lacunar infarction (LI) was also calculated. Results(1) The prevalenees of hypertentsion and diabetes mellitus were higher in elderly CKD patients than those in control group (30. 9% vs. 19.0%, 23.7%vs. 14.6%;both P～0. 05). (2) The percentages of grade 2 and grade 3 WMLs were higher in elderly CKD patients than those in control group (34.9% vs. 24.1%, 25.7% vs. 16.5%;both P<0.05). Prevalence of LI was higher in elderly CKD patients than that in control group (45.4% vs.25.3% ,X2= 13. 70, P<0. 05). The similar Resultswere also obtained except for control subjects with hypertension and diabetes mellitus. (3) The logistic regression analysis showed that age, hypertension and low glomerular filtration rate (GFR) were closely associated with SVD in elderly CKD patients. ConclusionsHypertention and diabetes mellitus are risk factors for CKD in elderly patients. SVD is associated with CKD, and age, hypertension and low GFR may be risk factors for SVD in elderly CKD patients.

Objective:To explore the value of two-dimensional speckle tracking echocardiographic imaging (2D-STI) for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion.
Methods:Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day, 3, 6 months post-PCI to examine left ventricular ejection fraction (LVEF), meanwhile 2D-STI was applied to obtain the global longitudinal strain (GLS) value of left ventricle.
Results:In all 23 patients, for LVEF, compared with pre-PCI (59.29±12.15)%, it was increased at 3 and 6 months post-PCI (60.00±12.35)%and (61.37±11.8)%respectively, all P<0.05;for GLS value, compared with pre-PCI (-12.77d wit )%, it was decreased at 1 day and 3, 6 months post-PCI (-13.23ecrea)%and (-15.67ecrea)%, (-16.97ecrea)%respectively, all P<0.05.
Conclusion:PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion, 2D-STI technology may quantitatively assess those changes at the early stage.

Objective To compare the predicting values for Prognosis among Global Risk Classification (GRS),Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) score,the European System for Cardiac Operative Risk Evaluation (EuroSCORE) in patients who received stenting because of unprotected left main coronary artery (ULMCA) lesion.Methods Totally 105 successive elderly patients with ULMCA lesion who received stenting were divided into 2 groups:with and without main adverse cardiac events (MACE).The clinical and angiographic characteristics were analyzed and then compared among GRC,SYNTAX score and EuroSCORE.Results As compared with none MACE group,MACE group had higher EuroSCORE score (2.0±2.3 vs.6.5±2.9,t=8.18,P=0.002),and more trivessel disease and left main bifurcation lesion (x2 =8.96,6.96,P =0.011,P =0.008).High risk GRC showed more MACE than medium or low risk GRC [55.9％ (19/34) vs.20.5％(9/44),7.4％ (2/27),x2 =19.77,P=0.001].AUC(95％CI )of GRC,SYNTAX score and EuroSCORE were [0.821 (0.730-0.912),0.586(0.462-0.709) and 0.631 (0506-0.757)],respectively.Compared with SYNTAX score and EuroSCORE,GRC was superior in the MACE predicting value (Z=3.29,2.63,P＜0.01 or P＜0.05).

Objective To investigate the compliance status of secondary prevention in patients with coronary artery disease (CAD) following revascularization.MethodsA total of 512 patients with CAD who received procedures for coronary revascularization were enrolled in the study from January 2009 to October 2010,including 472 cases of percutaneous coronary intervention stenting,25 cases of coronary artery bypass grafting and 15 cases of stenting plus bypass.The demographic information,prophylactic drug therapies, lifestylechangesandmodifiableriskfactorsweresurveyedwithquestionnaires,anthroposomatologicalmeasurementsandlaboratorytestsinpatients3monthsaftercoronary revascularization.ResultsThe proportion of patients on statins,aspirin,β-blockers,angiotensin-converting enzymeinhibitors/angiotensinreceptorblockers(ACEIs/ARBs)andinfluenzavaccinationwere 81.4％ (417/512),93.9％ ( 481/512 ),82.0％ ( 420/512 ),76.2％ ( 390/512 ) and 3.7％ ( 19/512 ) respectively.Based on the criteria recommended by the American Heart Association/American College of Cardiology (AHA/ACC)Guidelines for Secondary Prevention for Patients with Coronary and Other Atherosclerotic Vascular Disease: 2006 Update, the percentages of achieving therapeutic targets of modifiable risk factor management were as follows:glycosylated hemoglobin (90.2％,462/512 ),total cholesterol ( 68.6％,351/512 ),triglycerides ( 58.8％,301/512 ),high-density lipoprotein cholesterol ( 91.6％,469/512 ),low-density lipoprotein cholesterol ( 44.5 ％,228/512 ),systolic pressure ( 75.2 ％,385/512 ) and diastolic pressure (90.4％,463/512 ) respectively.And the proportions of improved lifestyle were as follows:smoking cessation/non-smoking 81.4％ (417/512),diet control 78.5％ ( 402/512 ),achieving weight targets 61.7％ (316/512)and regular exercise 58.2％ (298/512).ConclusionsThere is a relatively high percentage of standardized antiplatelet therapy and continuous statins medication in patients with coronary artery disease following revascularization. However,many significant modifiable risk factors have not been controlled optimally and lifestyle of patients needs further improvement. There is still a considerable scope for further improvement of secondary prevention in this group of patients.

Objective:To investigate whether T-cadherin affects the radiotherapy sensitivity of endometrial cancer cells by regulating the Caspase-1 mediated pyrolysis pathway.Methods:Endometrial cancer and adjacent tissue samples were surgically obtained from 82 patients admitted to Hainan Western Central Hospital from October 2019 to March 2021. Immunohistochemical staining and qRT-PCR were used to detect the expression of T-cadherin in endometrial cancer and adjacent tissue samples. By transfecting pcDNA3.1-T-cadherin lentivirus to human endometrial cancer cell line Ishikawa, a stable Ishikawa cell line with high T-cadherin expression was established. Ishikawa cells were treated with 2 Gy X-ray, and the cell proliferation activity was detected after 24, 48, 72 h of culture. The cells were divided into the control group (normally cultured Ishikawa cells), irradiation group (treated with 2 Gy X-ray irradiation), pcDNA3.1-NC+irradiation group (transfected with pcDNA3.1-NC followed by 2 Gy X-ray irradiation), pcDNA3.1-T-cadherin+irradiation group (transfected with pcDNA3.1-T-cadherin followed by 2 Gy X-ray irradiation), pcDNA3.1-T-cadherin+VA765+irradiation group (transfected with pcDNA3.1-T-cadherin, plus 10 μmol/L VA765 treatment followed by 2 Gy X-ray irradiation). After corresponding treatment, cell survival rate was detected by CCK-8 assay. Cell proliferation was determined by colony formation assay. The level of lactate dehydrogenase (LDH) release was measured by LDH release test. The expression levels of Caspase-1, interleukin (IL)-1β, IL-18 and gasdermin A (GSDMA) were detected by Western blot. The expression level of Caspase-1 was detected by immunofluorescence staining. SPSS 23.0 statistical software was used for data analysis. One-way ANOVA was used for data comparison among multiple groups. LSD- t test was used for two-paired comparison. Results:The positive expression rate of T-cadherin protein in endometrial cancer tissues was 6.09%, lower than 87.80% in adjacent normal tissues ( t=58.48, P<0.01). The relative expression level of T-cadherin mRNA in endometrial cancer tissues was 1.00±0.07, significantly lower than 4.02±0.38 in adjacent normal tissues ( t=32.35, P<0.01). The cell activity of pcDNA3.1-T-cadherin++irradiation group was decreased, the number of cell clones was decreased, LDH release level was increased, the relative expression levels of Caspase-1, IL-1β, IL-18 and GSDMA proteins in cells were up-regulated, and red fluorescence intensity of Caspase-1 protein was enhanced ( P<0.01). However, the cell activity of pcDNA3.1-T-cadherin+VA765+irradiation group was increased, LDH release level was decreased, the relative expression levels of Caspase-1, IL-1β, IL-18 and GSDMA proteins were down-regulated, and the red fluorescence intensity of Caspase-1 protein was also decreased (all P<0.01). Conclusion:T-cadherin can increase the radiotherapy sensitivity of endometrial cancer cells by increasing Caspase-1 mediated pyrolysis.
