Methaqualone and 2-methyl-3 [2- (hydroxymethyl) phenyl]- 4 (3H) quinazolinone (metabolite I) concentrations in human serum wereanalyzed quantitatively by reverse high performance liquid chromatography (RP-HPLC). The concentrations of methaqualone ranging from 1-35?g/ml were in good linear relationship(Correlation coefficient r = 0. 9980, regression line y = 0. 06324x-0. 1029), The average recovery of methaqualone reached as high as 102.08?9. 987(SD)% (n= 5). The detective limit was 1 ng. The relative quantity of metabolite I was determined according to the linear concentration of methaqulone. RP-HPLC assay is proved to be useful in determening blood methaqualone and metabolite I concentrations in forensic toxicology.

Objective To investigate the relevant data and aesthetic standards of hip and thigh profile in young females from the central plain area of China, aiming to provide a credible reference for the clinical application. Methods Measurements were made in 551 young healthy females aged 16 to 21 years, including waist circumference, hip circumference, maximum thigh circumference, thigh length and the ratio between thigh length and height. Based on these data, the features of the hip and thigh profile were analyzed. Results Waist circumference, hip circumference, maximum thigh circumference, thigh length and the ratio between thigh length and height were ( 70. 74 ± 5.86 ), ( 87.16 ± 4. 19 ), ( 51.87 ± 3.27 ),(42.35 ±2.38) cm and (26. 1 ± 1.23) %, respectively. The hip and maximum thigh circumference showed significant difference between different height and weight groups. The thigh length and the ratio between thigh length and height were positively correlated with height. Conclusion The parameters of hip and thigh profile in young females from the central plain area are of significant values in providing quantitative references for the plastic surgery and evaluation of the operation,especially in liposuction.

Six cases of suicidal sedative-soporific drug poisoning is reported.The main clinical features were coma,respiratory depression,hypotension,disappearance of reflexes and peripherel circulatory failure.Thepathological fingdings were as follows:pulmonary congestion and edema;fatty degeneration of the liver;degeneration of the epithalial cells of the proximal convoluted tubules and cerebral edema.The severityof the pathological changes depend upon the duration between the drug administration and the time of deathThe longer the course,the more prominent the changes.The fatality rate related with the dose of drugadministration,the underlying deseases and the complications.

Diagnosis of acute heart ischemia induced by coronary artery spasm(CAS)is not clear yet.We have systematically studied the histopathological,enzyme-histochemical and ultrastructural of the autolytic and the ischemic changes ofthe raf's heart induced by the injection of the pitutrin into the rat's sublingualvein.The PTAH stain demonstrated that some irregular transverse bands hadappeared in the muscular fibers.The adenosine triphosphatase activity in smallarteries was decreased.The author suggests that the results are helpful fordignosis of acute heart ischemia caused by CAS.

Object To develop a best approach for the rapid propagation of Lilium brownii F.E. Brown var. viridulum Baker by tissue culture. Methods Different parts of the bulb were tried as the explant and cultured on different culture media with the additon of different portions of various hormones at various cultural conditions. Results The best medium for the culture of explant bulb was MS+NAA 0.5 mg/L and GA 3 2.0 mg/L and the highest induction rate was at the lowest part of the scale leaves, which attained 92.5%. The small bud can further differentiate to form secondary small buds. By liquid-quivering culturing, the weight increase can be accelerated. Conclusion Tissue culture of L. brownii var. viridulum can achieve its rapid propagation, resulting in the possibility for its industrial production.

In recent years, the category of atopic dermatitis (AD) has been updated in domestic and foreign guidelines, and elderly AD has been added as a subtype. The pathogenesis of elderly AD is related to heredity, skin barrier dysfunction, immune dysregulation and lifestyle. Most elderly AD patients have atypical clinical symptoms, and misdiagnosis is very common. To fully understand the pathogenesis and clinical characteristics of elderly AD, and to formulate individualized diagnosis and treatment plans based on clinical characteristics, are particularly important for improving the quality of life of patients and reducing the burden of the disease.
