Vasovagal syncope (VVS)is the most common clinical unexplained syncope,and its pathogenesis has not been fully understood yet.The contradictory reflection of cardiac autonomic nervous system caused by riggerring Bezold-Jarisch reflex,which could cause dilated blood vessels,blood pressure and cardiac output decreased,insufficient blood supply to the brain relate with syncope occurrence.Currently,most people consider it mainly relatel to the age and gender of patients,history of syncope,family history,mental and psychological factors,dietary habits and other factors,but the exact risk factors of VVS remains further study of multi-center and a large sample of data.

ObjectiveTo explore clinical characteristics of fatality cases of hand foot and mouth disease caused by enterovirus 71 (EV71),and to improve the diagnosis and treatment of the disease.Methods Sixteen children infected with EV71 were retrospectively reviewed.Clinical manifestation,laboratory data and death causes were analyzed.ResultsAll cases were younger than four years,and the mean age was 18.9 months.Seasonal variations in incidence were observed,with a peak in incidence during the summer season.These cases typically presented with a brief duration of febrile illness,nonspecific neurological signs including headache,vomiting,limb tremor and convulsions.After two to four days,they all got sudden deterioration,manifested with tachycardia,poor peripheral perfusion,tachypnea and transient hypertension.After intubation,they all had pink frothy or blood from the endotracheal.Tweleve of them died from pulmonary edema or pulmonary hemorrhage,and acute refractory cardiac dysfunction.The other four of cases died from brain stem encephalitis.Atypical presentation such as absence of skin rash should alert the physician.Total white cell count,blood glucose and cardiac troponin I were raised significantly.The protein raised in cerebrospinal fluid.ConclusionHand foot and mouth disease caused by EV71 progresses rapidly.The primary site of attack is the central nervous system,particularly the brainstem,and the cause of death are neurogenic pulmonary edema and/or hemorrhage,acute refractory cardiac dysfunction.

Objective To obtain the information of therapies with beta blocker in patients with heart failure in our hospital. Methods 408 hospitalized cases in 2004 and 213 outpatients from April to July in 2005 with chronic heart failure from the cardiology department were collected. Results In hospitalized cases,of 54.9% patients were prescribed beta blocker,and only 4% of them arrived at target dosage and 24.9% of them arrived at half of target dosage. 86.1% of them were given metoprolol. The maximum dosage was (54.25?34.26) mg/d,the mean was equal to the 36.17% of target dosage. Among outpatients,77.5% were taken beta blocker,and only 2.5% of them reached the target dosage and 26.6% of them reached half of target dosage; and 89.7% of them were frequently given the metoprolol,the average dosage was up to 35% of the target dosage. Conclusions There was a great gap between the clinical practice and guideline of beta blocker therapy in patients with chronic heart failure. The prescribed dose of beta blocker was lower than the target dosage.

OBJECTIVE: To establish a method for endotoxin assay in aminoglycoside antibiotics for injection.METHODS: Kinetic turbidimetric limulus test was used for endotoxin assay in aminoglycoside antibiotics for injection.The recovery rate of bacterial endotoxin was determined though pre-interference experiments in which quantitative endotoxin was added to different concentrations of aminoglycosides with the concentration optimized,then an interference test on 4 different samples was conducted.RESULTS: At a concentration of 0.5 mg?mL-1,aminoglycosides didn't interfere with the limulus test if the amount of standard endotoxin was at 5.000,0.500,and 0.050 EU?mL-1,respectively.CONCLUSIONS: The kinetic turbidimetric limulus test could be used for endotoxin assay in aminoglycoside antibiotics for injection.
