Objective To explore the relevance between resting heart rate (RHR) and metabolic syndrome in young and middle-aged patients with essential hypertension.Methods Three hundred and forty patients with essential hypertension were enrolled in this study.According to the RHR,the hypertension patients were categorized into 3 groups:group RHR 1 (RHR ＜ 70 bpm,52 cases),group RHR 2(RHR 70-85 bpm,168 cases) and group RHR 3 (RHR ＞ 85 bpm,120 cases).The RHR,blood pressure,fasting blood glucose,triglyceride,high density lipoprotein cholesterol,2 h postprandial blood glucose and waistline were determined and compared.Results The level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure,diastolic pressure,and high density lipoprotein cholesterol in group RHR 1 were (4.96 ± 0.65) mmol/L,(6.85 ± 0.51) mmol/L,(1.69 ± 0.43) mmol/L,(78.3 ± 6.5) cm,(143.2 ± 5.6) mmHg (1 mmHg=0.133 kPa),(85.4 ±5.2) mmHg and (1.08 ±0.64) mmol/L.In group RHR 2 they were (5.66 ± 0.77) mmol/L,(7.94 ± 0.66) mmol/L,(2.58 ± 0.75) mmol/L,(88.6 ± 7.3) cm,(156.7 ± 6.1) mmHg,(93.6 ± 4.7) mmHg,and (0.95 ± 0.59) mmol/L.In group RHR 3 they were (6.85 ± 0.73) mmol/L,(8.97 ± 0.59) mmo]/L,(3.52 ± 0.90) mmol/L,(95.8 ± 9.2) cm,(164.3 ± 7.4) mmHg,(101.2 ± 3.5) mmHg and (0.78 ± 0.33) mmol/L.With the increase of RHR,the level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure and diastolic pressure increased step by step,high density lipoprotein cholesterol decreased step by step,and there were significant differences (P ＜ 0.05).Correlation analysis showed that RHR was positively correlated with fasting blood glucose,2 h postprandia blood glucose,triglyceride and waistline (r =0.52,0.45,0.50,0.36,P ＜ 0.05),and negatively correlated with high density lipoprotein cholesterol(r =-0.39,P ＜ 0.05).Conclusion RHR is closely related to the metabolic disorder in young and middle-aged patients with essential hypertension,and doctors should pay attention to the heart rate control while lowering blood pressure.

Pulmonary embolism(PE)is a relatively common cardiovascular emergency.Haemodynamic instability is the characteristics of massive pulmonary embolism,with a mortality as high as 20%.The goals of PE treatment are to remove the thromboembolic obstruction rapidly,exert beneficial effects on haemodynamic parameters and save the lives of patients.Haemodynamic and respiratory support is of vital importance in some critically ill patients with PE.The basic treatment is anticoagulation,the methods of which are different for PE during pregnancy,among cancer patients,with right heart thrombi and with heparin-induced thrombocytopenia.

Objective To optimize the medium for rhizomatous induction of Belamcanda chinensis in vitro. Methods By plant tissue culture technology, the effects of various carbon source, NAA, and active carbon at different concentration on the rhizomatous formation of B. chinensis in vitro were studied. Results MS+6-BA 2.0 mg/L+NAA 0.5 mg/L+6% white sugar was the optimal medium for the rhiz-omatous formation of B. chinensis in vitro. Active carbon should not be added to the medium. The germination rate of rhizomatous in vitro was 61.03% on the MS + BA 2.0 mg/L+3% white sugar. Conclusion Sugar concentration is the main factor of the influence on the rhizomatous formation of B. chinensis in vitro.

The neonatal burst suppression is a severe EEG pattern and always demonstrates serious damage of nerve system. But the outcome of these patients depends on the different etiology. A total of 256 cases of video EEG recordings were analyzed in order to summarize the etiology and outcome of burst suppression. The results showed that some patients in all 17 cases of burst suppression showed EEG improvement. The etiology was the dominant factor in long term outcome. It was suggested that effective video EEG monitoring is helpful for etiologic study and prognosis evaluation.
