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.

METHODS: The LC-MS method was used to detect the extractive of Chinese patent medicine for antihypertension in respects of relative molecular mass, tandem mass spectrometry fragment, retention time, UV spectrum. The compounds added into the Chinese patent medicine were identified by comparing with standard sample in terms of spectrum, chromatographic and mass spectrometric behavior. RESULTS: According to four aspects of determination, nifedipine, nitrendipine and nimodipine were found in three kinds of Chinese patent medicine for antihypertension. CONCLUSION: The method is selective and sensitive for the detection of nifedipine, nitrendipine and nimodipine which were added into traditional patent medicine illegally.

The aim of this study was to investigate the role of adhesion molecules P selectin (CD62P) in the pathogenesis of primary nephrotic syndrome (NS) and its relationship with its different pathological types. The expression of CD62P in renal biopsy tissue and peripheral blood platelets from patients with NS were measured with direct immunofluorescence labelling monoclonal antibody and flow cytometry respectively. The results showed that CD62P was expressed in 140/165 cases with NS (84 8%). Among these patients, renal expression of CD62P was lower in MN and FSGS patients than that in MPGN and MsPGN patients, and even lower in MCD patients. The expression of CD62P in peripheral blood platelets of patients with NS was significantly higher than that in the normal control group( P

Objective To study the main influence factors of nosocomial infection(NI) and establish a model to predict and forecast the risk of NI on patients in hospitals. Methods Clinical data of 27352 inpatients extracted from hospital information system were sorted out and coded, and a logistic regression model about the probability of NI was established. The risk of NI was divided into four scales. Results With multiple factor analysis,16 risk factors of NI were identified, which were age, high body temperature, numbers of diagnosis, days of staying in hospital and seriousness, numbers of routine test for urine, times of blood transfusion, use or without use of antibiotic and radiotherapy, turning over the bodies or not, relationships between infection and interventional operations, with or without diabetes, categories of diseases based on ICD-9, numbers of interventional operations, type of anesthesia and department of admission. If NI was judged when predicted probability(Pr)of logistic regression model exceeded 0 35, the specificity and false diagnostic rate of diagnostic test were 0 995 and 0 005 respectively, and the area under ROC curve was 0 986. According to decision tree method, the risk of NI was classified into four degrees: low (Pr

ObjectiveTo investigate the diagnosis and operative procedure for spontaneous perforation of congenital choledochal cyst in children. MethodsThe clinical data of 16 cases with spontaneous perforation of congenital choledochal cyst were analysed retrospectively.ResultsAll cases were under 4 years old with a mean age of 23 months. Abdominal distension, pain, vomiting, fever and diffuse tenderness were present in all patients. The preoperative diagnosis was established by paracentesis in ten patients. Abdominal sonography and CT found a cyst in 5 of the 10 cases reviewed. In 11 cases (68.7%), the site of perforation was found on the confluence of common bile duct and gallbladder cystic duct. T-tube drainage was used as a transition measure. All patients recovered uneventfully. Radical resection was performed in about three months after the initial operation. ConclusionsThe obstruction of the bile duct and poor blood supply to the choledochal cyst are major causes leading to perforation. Routine abdominal paracentesis should be carried out for a small child with peritonitis and general abdominal tenderness, especially on the right upper quadrant.T-tube drainage should be adopted as an emergent procedure to tide the patient over the crisis followed by elective choledochal cyst resection and bile duct reconstruction.

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.
