Objective To research clinical significance of electrocardiogram(ECG) measuring in diagnosis of hyperkalemia. Methods ECG changes and serum potassium concentration from 72 cases have been analyzed and contrasted. Results Forty-one cases with hyperkalemia are detected by ECG changes. Coincidence rate is up to 56.9% with serum potassium test. When the serum potassium concentration exceeds 5.5mmol/L, the accuracy of ECG in diagnosis of hyperkalemia was 22.2%. The main features arc peaked T wave with tabernacle shape ;when the serum potassium concentration exceeds 6.7mmol/L, the accuracy of ECG in diagnosis of hyperkalemia was 74.3%. The main features are ST debased,P wave with low amplitude and time limit increased. Some patients appeared sinus node-ventride conduction. One or two appeared malignant ventricular arrbythmia; when the serum potassium concentration exceeds 10.0mmol/L,the accuracy of ECG was 100% ,most patients appeared malignant ventricular. Conclusion The electrocardiogram measurement has the better consistency with serum potassium test, and abnormal electrocardio-gram will be eccurred,when mixed other electrolyte unbalance. Pseudo-hyperkalemia can be distinguished accurately and conveniently by using this method.

Objective To evaluate the combination use of transcatheter arterial chemoembolization (TACE), portal vein embolization (PVE) and high intensity focused ultrasound (HIFU) in treating portal vein tumor thrombus(PVTT). Methods A total of 85 patients with primary hepatocellular carcinoma complicated by PVTT, who were encountered during the period from Jan. 2011 to Feb. 2012 at authors’ hospital, were enrolled in this study. The patients were divided into the study group (n=47) and the control group (n=38). TACE, PVE and HIFU were performed in the patients of the study group, while only TACE and PVE were carried out in the patients of the control group. The therapeutic process was as follows: PVE was carried out 2 weeks after TACE was performed, and for the patients of the study group additional HIFU was conducted about 10 days after PVE procedure. Results The short-term effective rate in the study group and the control group was 89.4% (42/47) and 39.5% (15/38) respectively, and the difference between the two groups was statistically significant (P< 0.05). The 6-month, one-year, and two-year survival rate in the study group were 87.2%(41/47), 66.0%(31/47) and 27.7%(13/47) respectively; the median survival time was 15.4 months. In the control group, the 6-month, one-year, and two-year survival rate were 55.3% (21/38), 39.5% (15/38) and 10.5%(4/38) respectively;the median survival time was 10.3 months. The differences between the two groups were statistically significant (P< 0.05).

Objective To evaluate the protective effect of adiponectin in early atherosclerosis and the diagnostic value of adiponectin in metabolic syndrome in obese children. Methods Total 176 obese children and 88 normal weight children aged 9-12 years were included in the present study. All participants underwent hematologic and biochemical tests including serum adiponectin, high sensitivity C-reactive protein (hsCRP),fasting blood glucose, insulin, and plasma lipids. Homeostasis model assessment of insulin resistance (HOMA-IR)was calculated. Noninvasive ultrasound measurement including intima-media thickness of the common carotid artery(IMT), brachial flow-mediated dilatation (FMD), carotid artery compliance (CAC), and the maximum fatthickness ahead of peritoneum (Pmax) were obtained to investigate arterial mechanical properties and endothelial function. Results (1) The level of adiponectin was negatively correlated with obese index, blood pressure,fasting insulin, hsCRP, HOMA-IR, and IMT(P<0.05 or P<0. 01 ); but not with triglyceride, fasting blood glucose, CAC, high-density lipoprotein-cholesterol (HDL-C), and FMD. (2) The risk of metabolic syndrome increased 3.43 times in children with adiponectin level <7. 060 mg/L compared with ＞7. 060 mg/L. (3)Receiver operating characteristic( ROC ) curve was used to choose the optimal cutpoint of adiponectin to identify obese children with the metabolic syndrome. The area under the curve (AUC) for adiponectin to discriminate the sensitivity of metabolic syndrome was 0. 769 (95% CI0. 714-0.816, P< 0. 0 1 ). (4) The obese children were divided into three groups according to the cut-off value for adiponectin (high, middle, low groups). There were significant differences in the prevalences of severe obesity, visceral fat accumulation, hypertension, insulinemia,low HDL-C, metabolic syndrome among three groups (P<0.05). Conclusions High levels of serum adiponectin could prevent early stage of atherosclerosis. The lower the adiponectin level, the higher the incidence of metabolic syndrome.

The detection rate of dizziness, insomnia, white coating, thin coating, etc. were higer in women than that in man (P<0.01). The detection rate of teeth shaking, greasy fur, yellow fur, string pulse, etc. were higher in man than that in woman (P<0.01). The detection rate of teeth shaking, dry eyes, thirst, dark tongue, red tongue, string pulse, etc. in the elderly group were higher than the middle-aged one (P<0.01). The detection rate of irritability, numbness, shortness of breath, scalloped tongue, thin coating, deep pulse, etc. in the middle-aged group was higher than the aged one (P<0.01). Conclusion The clinical manifestations of high-risk group of stroke are complicated. There were root deficiency such as deficiency of spleen and kidney, and branch excess such as wind-fire and phlegm-stasis. Difference and regularity were showed in different gender and different age groups to some extent.

Objective To investigate the effects of Xueshuantong injection on levels of inflammatory factors and homocysteine (Hcy) in patients with acute cerebral infarction.Methods 128 patients of acute cerebral infarction who received therapy in the hospital from January 2014 to May 2015 were collected as research objects to retrospectively analyze their clinical materials.According to therapeutic schemes, those patients were divided into control group (n=62) and observation group (n=66).The control group were given conventional treatments, such as anti-platelet aggregation, lipid regulation, maintaining balance of water-electrolyte and acid-base, controlling blood glucose, controlling blood pressure and so on.Besides that, the observation group were given Xueshuantong injection.After two weeks treatment, the curative efficacy, levels of inflammatory factors as high-sensitivity C reactive protein (hs-CRP), tumor necrosis factor α(TNF-α), interleukin 8 (IL-8), Hcy and adverse reactions were compared.Results The total efficacy of observation group was 93.9%, which was statistically higher than that of 80.6%in control group (χ2 =5.166,P=0.023).After treatment, hs-CRP, TNF-α, IL-8 levels in observation group were significantly lower than those in control group (all P<0.05).After one and two weeks treatment, The Hcy level in observation group was statistically lower than that in control group ( all P<0.05 ).The adverse reactions in observation group was 8 cases ( 12.1%), 6 cases ( 9.7%) in control group, with no significant difference between two groups (χ2 =0.196, P =0.658 ). Conclusion Xueshuantong injection is effective in treatment of acute cerebral infarction, which could significantly increase curative efficacy, alleviate inflammatory reaction and reduce level of Hcy with less adverse reactions.
