ABSTRACT

@#Objective    To investigate the application of ascending aorta cannulation and brachiocephalic trunk cannulation in acute type A aortic dissection. Methods    We screened 183 patients with acute type A aortic dissection from January 2017 to January 2020 in our hospital. They were divided into 2 groups according to the cannulation strategy: ascending aorta cannulation and brachiocephalic trunk cannulation (a DAC group, n=42, 33 males and 9 females with a median age of 50 years) and the single axillary artery cannulation (an AAC group, n=141, 116 males and 25 females with a median age of 51 years). The general clinical data, intraoperative data and early postoperative results of the two groups before and after matching with propensity scores were compared. Results    Before propensity-score matching, the operation time, cardiopulmonary bypass time, aortic occlusion time and ICU stay in the DAC group were all shorter than those in the AAC group (P<0.05). The early postoperative mortality, and rates of brain complications, renal failure and pulmonary complications in the DAC group were significantly lower than those in the AAC group. After propensity-score matching, the operation time in the DAC group was significantly shorter than that in the AAC group (P<0.05). The early postoperative mortality, and rates of brain complications and pulmonary complications in the DAC group were significantly lower than those in the AAC group. Conclusion    Ascending aorta cannulation and brachiocephalic trunk cannulation can provide a safe, fast and effective method of establishing cardiopulmonary bypass for some acute type A aortic dissection patients, and significantly shorten the operation time without increasing surgical complications.

ABSTRACT

Objective:To construct and confirm a predictive model for the risks of cardiovascular diseases (CVD) with metabolic syndrome (MS) and its factors in Xinjiang Kazakh population.Methods:A total of 2 286 Kazakh individuals were followed for 5 years from 2010 to 2012 as baseline survey. They were recruited in Xinyuan county, Yili city, Xinjiang. CVD cases were identified via medical records of the local hospitals in 2013, 2016 and 2017, respectively. Factor analysis was performed on 706 MS patients at baseline, and main factors, age, and sex were extracted from 18 medical examination indexs to construct a predictive model of CVD risk. After excluding the subjects with CVD at baseline and incomplete data, 2007 were used as internal validation, and 219 Kazakhs in Halabra Township were used as external validation. Logistic regression discriminations were used for internal validation and external validation, as well as to calculate the probability of CVD for each participant and receiver operating characteristic curves.Results:The prevalence of MS in Kazakh was 30.88%. Seven main factors were extracted from the Kazakh MS population, namely obesity factor, blood lipid and blood glucose factor, liver function factor, blood lipid factor, renal metabolic factor, blood pressure factor, and liver enzyme factor. The area under the curve (AUC) for predicting CVD in the internal validation was 0.773 (95% CI 0.754-0.792). In the external validation, the AUC for predicting CVD was 0.858 (95% CI 0.805-0.901). Conclusions:The CVD risk prediction model constructed by 7 main factors extracted from Kazakh MS patients has high validation efficiency and can be used for risk assessment of CVD in Xinjiang Kazakh population.

ABSTRACT

Objective@#To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease(CVD)among Kazakhs population.@*Methods@#The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve.@*Results@#The incidence of CVD was 13.87%. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59% vs 11.10%, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001); the area under the curve of MS risk score was close to that of Framingham risk score(0.732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61, 9.33, 14.15, 22.29 vs 3.69, 6.36, 8.47, 16.99).@*Conclusion@#MS risk score that included age may be a better predictor of CVD among Kazakhs population.

ABSTRACT

BACKGROUND: The study on the candidate gene of schizophrenia was one of the major ways of exploring its etiology. One of important candidate genes associated with schizophrenia is the brain-derived neurotrophic factor gene(BDNF)OBJECTIVE: To explore the association between schizophrenia and C270T polymorphism of BDNF gene.DESIGN: Case-control and comparative observation SETTING: Institute of Mental Health of Central South University PARTICIPANTS: Totally 194 patients with schizophrenia, including 95 males and 99 females aged from 15 to 59 years, hospitalized in man and women wards in the Institute of Mental Health, Xiangya Second Hospital of Central South University from March to October 2003 were set as patients group. Controls were selected among the healthy volunteers of Xiangya Medical College was included in terms of age and gender comparable with patients group. Altogether 187 cases of controls, of whom 88 males and 99 females were studied. Their age ranged from 18 to 42 years old with the average of (26±7) years old.Those with psychosies and severe somatopathy were excluded. The patients and their family member have no history of psychosis .All the subjects were of Hunan Han nationality. Either the patient or his or her family members signed the written consent form. Individuals in the control group also signed the written consent form.positive symptom scale (PANSS-P) (7 items), negative symptom scale (PANSS-N) (7 items) and General Symptom Scale (PANSS-G) (16 items),altogether 30 items, as well as 3 additional items to evaluate the attack fatalness were used to evaluate whether the psychic symptom existed or not and the degree of severity of each symptom(7-item scoring: 1 was without,7 was very severe) . The patients were evaluated on the day of hospitalizing was used to compare the frequency among groups.polymorphism of BDNF gene between patients group and healthy control RESULTS: Totally 194 patients with schizophrenia and 187 healthy genotype (26.8%) in patients was much higher than that of the healthy controls (5.9%) (x2=32.71, df=1, P < 0.01).The distribution frequency of T allele in patients' group (14.4%) was much higher than that in the scores, PANSS-P, PANSS-N and PANSS-G scores in patients with the genotype of C/T were 59-121 ;9-42( average 20.08±6.16);8-41 (average 19.02±9.13);22-68 (average 36±8.02)respectively. And the total PANSS scores, PANSS-P, PANSS-N and PANSS-G scores in patients with the genotype of C/C were 58-121 ;7-39, (average 19.2±5.88);8-40scores, (average19.02 ±8.98); 22 -68 (average36.4 ±8.32)respectively.There were no significant differences in positive and negative symptom scale (PANSS)items as well as PANSS-G between the patients with C/C and C/T genotype(P > 0.05).CONCLUSION: BDNF gene C270T polymorphism was associated with the susceptibility of schizophrenia. The distribution frequency of T/C genotype and T allele in schizophreniac was significantly higher than those of the normal healthy controls. And no significant difference was obtained between patients with the genotype of T/C or C/C in terms of negative,positive symptoms and psychosocial function as well.
