Objective To compare the effects of vasopressin and adrenaline on cerebral resuscitation in rats. Method Sixty male SD rats were used to set the animal model of cardiac arrest and were randomly (random number) divided into 4 groups (n = 15/group): sham operation group (sham-gro), negative control group (neg-gro), vasopressin group (vas-gro) and adrenaline group (adr-gro). Blood pressure was recorded, and brain tissue samples were obtained. Results There was no significant difference in the recovery rate between vas-gro and adr-gro 30 min after resuscitation (P ＜0.05). The mean blood pressure in vasgro was higher than that in adr-gro within 30 min (1,2, 5, 10, 20, 30 min) after restoration of spontaneous circulation. The measured MDA, SOD and GSH were significantly different (P ＜ 0.05) between each two groups among vas-gro, sham-gro and adr-gro. Conclusions The recovery rate was similar between vasopressin group and adrenaline group during cardiopulmonary resuscitation in rats. However, vasopressin can to maintain the mean arterial pressure at a higher level after resuscitation, which can the increase the cerebral perfusion and reduce brain cell damage.

BACKGROUND: International research discovers that the risk factors of stroke have certain correlation with microalbuminuria(MAU) but the results are inconsistent.OBJECTIVE: To investigate the relationship between the incidence of MAU in patients with acute cerebral infarction and the risk factor of stroke and the recurrence of cerebral infarction.DESIGN: A case-control study based on patients with acute cerebral infarction and individuals with risk factors of cerebral infarction, and the healthy elderly as controls.SETTING: Inpatient department of neurology in a university hospital.PARTICIPANTS: Totally 214 cases with cerebral infarction or risk factors of cerebral infarction aged between 50 and 80 years old were selected from the Department of Neurology of the First Affiliated Hospital of Chongqing Medical University between January 2000 and December 2001. Acute cerebral infarction group (infarction group, attack within one week, n =78), cerebral infarction risk factor group(risk group, n = 56), such as, hypertension, diabetes,coronary heart disease (CHD), transient ischemic attack(TIA) or stroke history(more than 6 months), and healthy elderly(control group, n=28) .Thereinto, combined group( n = 109) included 78 cases of acute cerebral infarction and 31 cases with TIA or stroke history of risk factors.METHODS: Seralbumin, serum creatine(SCr), blood sugar, total cholesterol, total triacylglycerol(TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol(LDL-C) were detected after more than 12 hours of fasting. The albumin in the first urine in the morning was detected by radio-immunity analysis.the incidence of neo-vascular affair in 2 years of follow-up including recurtute indicator: incidence of MAU in each group.RESULTS: Patients with MAU accounted for 35% of acute cerebral infarction, which were significantly higher than that of risk group(15% ) and control group(3.5%, P ＜ 0.01). Six independent risk factors predicting MAU existed in infarction group and combined group, which were diabetes, seralbumin level, age, CHD, hypertension, and HDL-C( P ＜ 0. 05, or P ＜ 0.01).After(1.5 ±0. 9) years of follow-up, 23% of patients of infarction group suffered from recurrent vascular accident, which was significantly higher than that of risk group(12% ) and control group(0%, P ＜ 0.01 ). 36% of MAU patients in infarction group suffered from recurrent vascular accident, which was significantly different from that of patients with a great deal of albuminuria(41% ) and normal albuminuria(10%, P ＜ 0. 05). MAU is the independent predicting indicator for the recurrence of stroke after the control of diabetes and hypertension in patients of infarction group and risk group with the risk rate of 3.8 (95% CI, 1.2-13.5; P ＜0.05) or 4. 7(95%CI,1.4-16.7, P ＜ 0.01).CONCLUSION: MAU is quite common in acute cerebral infarction patients. After the adjustment of basic risk factors, MAU is the independent risk factor of the recurrence of cerebral infarction.

ObjectiveTo investigate the value of ultrasonography in the diagnosis of the papillary thyroid microcarcinoma (PTMC) in patients with Hashimoto’s thyroiditis (HT).MethodsThis retrospective study used data from Ruijin Hospital of Shanghai Jiaotong University of Medicine during November 2012 to December 2013. A total of 111 small thyroid nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The sonographic characteristics of nodules were investigated, including nodule aspect ratio, shape, border, margin, acoustic halo, internal structure, echo level, microcalciifcations, rear acoustic attenuation, vascular pattern and extent of the blood supply and the types of thyroid tissue echogenicity. Chi-square test and Fisher′s exact probability method was used to compare the differences of the sonographic characteristics between the benign nodules and malignant nodules. With surgical pathology as the gold standard, computing the value of ultrasonography in the diagnosis of PTMC with HT, including the sensitivity, speciifcity, diagnostic accuracy, positive predictive value and negative predictive value.ResultsA total of 111 thyroid tiny nodules (75 PTMC/36 benign nodules) with 107 HT cases which were pathologically conifrmed were included in this study. The results showed 111 small thyroid nodules as solid hypoechoic. Four indexes between PTMC and benign nodules had statistical signiifcance, such as margin, microcalciifcations, vascular pattern and extent of the blood supply. The other six indexes between PTMC and benign nodules had no statistical significance, such as aspect ratio, shape, border, acoustic halo, rear acoustic attenuation and the types of thyroid tissue echogenicity. Ultrasound diagnostic accuracy of small tyroid nodules in patients with HT was 74.77% (83/111). The sensitivity, specificity, diagnostic accuracy, positive predictive value and negative predictive value of the ultrasound diagnosis of PTMC were 93.33% (70/75), 36.11% (13/36), 74.77% (83/111), 75.27% (70/93), and 72.22% (13/18), respectively.ConclusionsCompared with general population, some classic ultrasound features became less effective in patients with HT. However, ultrasonography has some differential diagnostic value in these cases.
