OBJECTIVE:To establish a simple method for drug bioequivalence test based on Excel function.METHODS:The statistical tests including ANOVA,two one-side test and 90% confidence interval were carried out using Excel statistical function.RESULTS:Drug bioequivalence test can be performed based on Excel,with results in line with those stated in Biopharmaceutical and Pharmacokinetic.Moreover,due to Excel's repeated calculation function,for retest,three kinds of test results were available rapidly only by replacing the data with others remained for calculation.CONCLUSION:Excel function can be used to calculate drug bioequivalence.

OBJECTIVE:To calculate pharmacokinetic parameters and compartment model's parameters by extravascular administration based on Excel function.METHODS:The parameters of pharmacokinetics and compartment model were calculated using residual method and Excel function.RESULTS:Excel can be used to directly demonstrate calculation process of parameters of pharmacokinetics and compartment model,with calculation results in line with those stated in textbooks.CONC-LUSION:The established method is simple,direct-viewing,reliable and easy to be extended,and it can be used to calculate pharmacokinetic parameters in clinical teaching or experiments.

Through the investigation of Phellodendron Cortex on the market, and 28 batches of samples were collected. By using spectrophotometer the color values of outer surface, inner surface and cross - section of these samples were measured. These measured color data was translated into 3D structure diagram by using the Lab color space tool. The level difference value, the mean value and the threshold value were calculated based the measured color data of these different batches of samples. All 28 groups measured data was analyzed using the methods of Ward linkage and average Euclidean distance. At the same time, we invited Professor Jin Shiyuan, the "Chinese medicine master", to identify, quality-evaluate and grade these 28 batches of Phellodendron Cortex samples base on the traditional experience, then compared the traditional empirical results with the spectrophotometer measurement results. The result showed that, the Phellodendron Cortex could be divided into Phellodendri Amurensis Cortex and Phellodendri Chinensis Cortex by color numerical clustering, and classified according to quality. The classification result has a high degree of consistency with the traditional experience.

Objective To study the clinical values of positron emission tomography(PET)in pre-term and term newborn infants through observing neonatal brain by 18F-fluorodeoxyglucose(18F-FDG)PET.Methods The brain by 18F-FDG PET in 11 term and 7 pre-term newborn infants after administration of 0.1 mCi /kg 18F-FDG were observed.There were 11 males and 7 females,who were normal by brain computed tomography or magnetic resonance imaging.Results The brain 18F-FDG PET image in pre-term and term newborn infants was relatively high in thalamus,and relatively low in cerebral cortex,whereas the total brain was different with adults.Especially in the area of cerebral cortex,the uptake of glucose was relatively higher,and the structure of brain 18F-FDG image was more clear in term infants than that in pre-term infants.Conclusion Neonatal brain picture by 18F-FDG PET is a new tool for predicting the brain function,and its clinical values need further investigating.

Objective To explore the changes of positron emission tomography(PET)in newborn infants with HIE through 18F-fluorodeoxyglucose(18F-FDG)and it's significance.Methods Eleven healthy newborn infants and 8 newborn infants with HIE were selected.Among the healthy newborns,7 cases were male and 4 cases were female,and the mean birth-weight was(3 350?620)g,the gestational age was(37.9?1.3)weeks.Among the HIE neonates,5 cases were male and 3 cases were female,and the mean birth weight was(3 180?390)g,the gestational age was(37.1?2.4)weeks.There were no significant differences of sex and gestational age between the 2 groups.The examination time was form 3 to 21 d,and the mean age was(8.7?3.9)d.PET of the children in 2 groups were observed after 0.1 mCi/kg 18F-FDG injected 30 min.Results The brain 18F-FDG PET image in newborn infants was relatively high in thalamus,and relatively low in cerebral cortex,whereas the total brain was different with that of the adults,and that was not as clear as that of adults.Especially in the area of cerebral cortex,the uptake of glucose was relatively higher.The structure of brain 18F-FDG image was significantly changed in newborn infants with HIE,especially increased in the areas of peripheral ventricle and hypophloeodal cerebral white matter,and there was a remarkably bilateral asymmetry.Conclusions Neonatal brain picture by 18F-FDG PET is a new tool for predicting the brain function,and its clinical values need further investigating.

Objective To probe the cause of the infant nutritional iron deficiency anemia,so to decrease effectively the percentage of afflicting such ill.Methods Investigate,count and analyze 418infants'data on brease-feeding and subsidiary food-feeding.These infants aging 6 months,1 year and 1.5years,visited Zhengzhou Maternal and Child Health Hospital periodically.Results The affliction percentage of infants aging 6 months,1 year and 1.5 years,is 26.11%,19.17%and 11.02%respectively,a significant difference may be found between the value(X2=10.28,P＜0.05);The affliction percentage of the breast-fed and non-breast-fed infants aging 6 months iS 22.46%and 38.10%,a significant difierence may also be found between the value(x2=4.08,P＜0.05);The affliction percentage of the mother's milk is rich and unitary infants aging 6 months is 16.50%and 40.00%.a significant difierence may also be found between the value(x2=8.28,P＜0.05).Conclusions Mother's milk is the ideal food for infants;subsidiary food shall be added timely and properly when the infant ages 6 months;infant systematic caring plays a very important role in the infant development,all intensive project on this issue must be carried out seriously.

OBJECTIVE To investigate the clinical features and causes of nosocomial infection in schizophrenics with tuberculosis so as to take effective measures for better prevention and treatment.METHODS A retrospective investigation was used to analyze the clinical features and causes of nosocomial infection in 207 schizophrenics with tuberculosis.RESULTS The rate of nosocomial infection in schizophrenics with tuberculosis was 39.13%.The main infection way was via respiratory tract,followed by skin,soft tissue and gastrointestinal tract.The period and degrees of tuberculosis,the history of smoking,psychiatric symptoms and the complications were the causes of nosocomial infection.CONCLUSIONS Controlling psychiatric symptoms actively,preventing and treating somatic complications,using antibiotics rationally and less or no smoking are the effective measures to avoid nosocomial infection in schizophrenics with tuberculosis.

Objective To investigate the effects of hepatocyte growth factor(HGF) on proliferation and collagen synthesis induced by angiotensin Ⅱ(AngⅡ)in SD rat cardiac fibroblasts(CFbs),and determine the role it plays in hypertensive ventricular remodeling.Methods CFbs in SD rat were cultured in vitro and treated with different concentrations of AngⅡ and/or HGF.Collagen type Ⅰ synthesis of CFbs was measured by Western blotting,and proliferation of CFbs was detected by MTT assay. Results AngⅡ promoted collagen synthesis and proliferation in CFbs in a certain concentration range,which can be significantly inhibited by HGF. ConclusionHGF can inhibit the proliferation and collagen synthesis induced by AngⅡin SD rat CFbs,and may protect against hypertensive ventricular remodeling.
