OBJECTIVE:To determine the concentration of ozagrel in human plasma by RP-HPLC.METHODS:The sample separation was performed on a SinoChrom OPS-AP column.The mobile phase consisted of 0.025 mol?L-1 potassium dihydrogen phosphate buffer solution-acetonitrile(85∶15) with a flow rate of 0.8 mL?min-1 and a detection wavelength of 274 nm.The internal standard was levodropropizine.RESULTS:The linear range of ozagrel was 0.7～21.3 ?g?mL-1,(r=0.999 6).The extraction recovery of ozagrel was 83.78%～89.14% and the methodological recovery of it was 101.95%～106.68%.The intra-day RSD and inter-day RSD were 1.33%～3.27% and 2.72%～5.97%,respectively.CONCLUSION:This method is simple,rapid,accurate and reproducible,and it is applicable for the pharmacokinetic study of ozagrel in human plasma.

OBJECTIVETo verify the clinical efficacy on post-stroke dysphagia treated with acupuncture at Lianquan (CV 23).

METHODSOne hundred and eighty patients were randomized into an acupuncture A group, an acupuncture B group and a rehabilitation group, 60 cases in each one. On the basis of the conventional medication, in the acupuncture A group, acupuncture was applied at Lianquan (CV 23); in the acupuncture B group, acupuncture was applied at Hegu (LI 4) and Neiguan (PC 6) and in the rehabilitation group, the swallowing rehabilitation training was adopted. The treatment was given once a day, 5 times a week, and the 4 weeks of treatment was required in all of the groups. The national institute of health stroke scale (NIHSS) and TV X-ray fluoroscope swallowing scale (VFSS) were used to evaluate neurologic deficit and swallowing function before and after treatment in the patients of each group. The morbidity of pneumonia and clinical efficacy were compared among the groups.

RESULTSThe scores of NIHSS and VFSS were improved apparently after treatment in the patients of the three groups (all P < 0.05) and the results in the acupuncture A group were superior to those in the other two groups (all P < 0.05). The morbidity of pneumonia in the acupuncture A group was lower than that in the acupuncture B group and the rehabilitation group [3.3% (2/60) vs 6.7% (4/60), 8.3% (5/60), both P < 0.05]. The effective rate in the acupuncture A group was better than that in either of the other two groups [95.0% (57/60) vs 81.7% (49/ 60), 75.0% (45/60), both P < 0.05].

CONCLUSIONOn the basis of the conventional medication, acupuncture at Lianquan (CV 23) effectively improves the swallowing function, relieves neurological deficit and reduces the morbidity of pneumonia in the patients of post-stroke dysphagia.

Objective In order to investigate the clinical feature in children with family of coronary heart disease(CHD).Methods The clinical study were analysed in 83 children with family of coronary heart disease.Results In 83 children with family of coronary heart disease , most of them were school children and boys .Their grandparent and law grandparent had CHD in most of children. The incidences of overweight ,obesity and hypertension were higher .There was lipids metabolism abnormality . There abnormal indices had more remarkable in children with family of premature CHD. There were not hyperglycemia in children with family of coronary heart disease.Conclusion There is abnormality of weight ,lipids metabolism and blood pressure in children with the family of CHD .It is obviously in children with family of premature CHD,suggesting the children should be treated as soon as possible.

Objective To establish the method to detect the expression of apolipoprotein E gene in human adipose cells. Methods Apolipoprotein E gene expression was determined by competitive reverse transcription-PCR in adipose cells of healthy children. Results Apolipoprotein E gene expressed in the adipose cells of healthy children. The mean expression quantity of apolipoprotein E mRNA in adipose cells was (0.41?0.12 ) in healthy children. Conclusions Competitive reverse transcription-PCR is a rapid, simple, sensitive and accurate method to analyze expression of apolipoprotein E gene.

Computed tomography perfusion imaging can accurately and promptly provide hemodynamic parameters of brain tissues after stroke,and it has a good correlation with the accepted hemodynamic measurement,the parameters got from xenon-computed tomography, functional magnetic resonance imaging and positron emission tomography.Therefore,CTP has been widely used in predicting the studies of ischemic penumbra after stroke.

The prognosis and outcome in patients with intracerebral hemorrhage are closely correlated with perihernatoma tissue injury and recovery.The pathophysiological mechanisms after intracerebral hemorrhage are extremely complicated.There are regional blood flow changes in perihematoma tissues,but whether there is a similar“penumbra”as in cerebral ischemia remains uncertain.At present,studies in this field have mainly focused on the imaging detection of regional cerebral blood flow and metabolism.The study methods frequently used include single photon emission computed tomography,functional magnetic resonance imaging,magnetic resonance spectroscopy,positron emission tomography and CT perfusion imaging,etc.The application of these imaging techniques have provided some valuable methods for identifying whether perihematoma penumbra is present or not,but further studies are needed to confirm it.

Objective To investigate the application of a new type internal anastomotic appliance of pouch pliers in the retention of anus operation of mesal,low rectal carcinoma.Methods The data of 65 patients with mesal,low rectal carcinoma with the technique of the anal retention using KYGW type anastomotic appliance of pouch pliers were reviewed and analyzed retrospectively.Results 65 patients were coincided success only one time. Anastomotic fistula occurred after operation in 1 case,being cured and discharged at last,no anastomotic stricture. Conclusion The internal anastomotic appliance of pouch pliers in the anal retention of mesal-low rectal carcinoma is an efficient method with better cost-effectiveness and fewer complications,which is easy to manipulate and popular- ize.
