Objective To study relation between tumor blood vessels around hepatocellular carcinomas and metastases and try to find out probability to predict potential metastases of hepatocellular carcinomas according to CT manifestation.Methods Both CT plain scans and dynamic contrast scans were taken in 134 cases of patients with hepatocellular carcinomas.The tumor blood vessels around and in cancers were counted.CT appearances,pathology results and patient follow-up were compared and analyzed.Results 1.The possibilty to happen metastases was much higher in carcinomas with heavy enhancement than that with gently or middle.2.Those with tumor blood vessel around neoplasm were greater metastasis rate than those without them.3.The enhancement degree in tumor border is positive correlation with blood count.Conclusion The latent metastases can be estimated according to the enhancing degree and tumor blood vessels around carcinomas.

Vascular endothelial growth factor(VEGF) is one of the best characterized angiogenic regulators which has many effects in promoting endotheliocyte proliferation and differentiation,increasing the microvascular permeability,inducing the angiogenesis,triggering the growth,survival and migration of tumor cells by combining its specificity receptor (VEGFR).Dysregulation of VEGF expression and signaling pathways therefore plays a pivotal role in the pathogenesis and clinical features of hematologic malignancies,direct and indirect targeting of VEGF and its receptors therefore may provide a potent novel therapeutic approach to overcome bone marrow angiogenesis and multidrug resis-tance thereby improve patient outcome.Recent years,a novel VEGF blockade system using RNA interference attracts more and more people's attention.The small interfering RNA (siRNA) targeting VEGF/VEGFR can completely inhibits the expression of VEGF and induce the silence of corresponding genes.

Objective To evaluate the efficacy and safety of topiramate(TPM) as add - on drug treating infants with severe epilepsy. Methods We performed prospective label add - on study in 12 infants (aged 4 to 19 months) with sever seizures of different types. TPM was add - on one or more other baseline drugs and the efficacy was evaluated according to seizure type and frequency Results TPM initiated in a daily dose of 0.5 - 1 0 mg/kg, followed by a 1 - 2 weeks titration on the increase of 0 5 - 1.0 mg/kg up to a maximum daily dose of 4 - 10 mg/kg. After a mean period of 6 2 months (range 3- 13 montks), Total efficacy was 75 % and 50 % were controlled completely. Seizure frequency was unchanged in 3 patients (25 % ). As for seizure type, TPM was more effective in complex partial as compared with generalized tonic-conic seizures. Mild adverse events were present in 3 patients (25 %), represented hypersonia, fever and decreased speech. Conclusions TPM may be a available drug in infants with severe epilepsy. It is safe, with mild adverse effect in fewer patients.JAppl Clin Pediatr,2004,19(11):986-987

Objective: To inquire into the testis gene change of mouse model with kidney-yang deficiency induced by overfatigue and excessive sexual life, the modern science mechanism of syndrome of kidney-yang deficiency and kidney controlling reproduction can be revealed on the gene level. Methods: The model of kidney-yang deficiency was established by each male mouse with six female mice keeping in the same cage, and all the male mice were forced to swim for 30-40 minutes everyday lasting for four weeks. The testis genes of mice in control group and model group were detected with Mouse OneArrayTM Whole Genome DNA microarray. The differentially expressed genes were screened under the condition of the relative fluorescence intensity ratio of the two groups ≥2 and ≤0.5 and further classified according to gene function by using Molecule Annotation System (MAS) created by CapitalBio Corp. Beijing, China. Results: The mouse model with kidney-yang deficiency was established successfully by the method of overfatigue and excessive sexual life. The scatter plot of gene expression profiles of comparing control group with model group was drawn. Differentially expressed genes were screened, including 2425 up-regulated genes and 3080 down-regulated genes. Among the first one hundred up-regulated genes, 41 genes were known and among the first one hundred down-regulated genes, 62 genes were known. These genes were mainly related to the cellular structure/function, material/energy metabolism, signal transduction/transmission, inflammation/immunization, cell apoptosis, transcription/translation,proliferation/differentiation and cell cycle. Conclusion: The testis gene of kidney-yang deficiency mouse had a wide change. The essence of kidney-yang deficiency syndrome and the theory of the kidney originating and controlling life reproduction were explained on the gene level.

After several thousand years of development,TCM has formed its own sets of research methods.such as observation,comparison,classification,trial and error,and deduction,etc.Based on the unique TCM theory,experiences of clinical diagnosis and treatment of TCM,the author put forward that the research of TCM should combine macrophenomenon and microphenomenon,quality and quantity,and"Zheng"and"Xie",emphasize locality feature for the purpose of promoting the science research level.

This study is to explore that how to use the information management system to research composed of the management and sharing of research projects,study exchanging and technical guidance.The purpose is to improve the management efficiency and level of scientific research projects.Current study aimed to explore establish a digital management system

Objective To observe the pregnancy outcome of perinatal in drugs abuse pregnant women.Methods The clinical data of 105 cases of newborn in pregnant women with drug abuse were analyzed retrospectively,including premature,neonatal asphyxia,low birth weight,neonatal respiratory distress syndrome (NRDS),intracranial hemorrhage,neonatal congenital malformation and death.Fifty cases of newborn of healthy pregnant women were selected as control group.The occurrence of neonatal withdrawal syndrome was observed.Results There were 80 cases of natural labor,25 cases of cesarean section in 105 cases of pregnant women with drug abuse.Among them,56 cases (53.3 ％) of premature delivery,the average birth weight was(2 534 ± 1 234) g,25 cases(23.8％) of neonatal asphyxia,18 cases(17.1％) of neonatal respiratory distress syndrome (NRDS),16 cases (15.2 ％) of intracranial hemorrhage,and 3 cases (2.9 ％) of congenital malformation.The gestational age and weight of newborn with maternal drug abusing were significantly lower than those of the control group,the incidence of premature infants,low birth weight infants,neonatal asphyxia,NRDS and intracranial hemorrhage were higher than those of the control group,and the differences were significant (P ＜ 0.05).Compared with drug abuse less than 2 years,the proportion of preterm infants,low birth weight,neonatal asphyxia and NRDS were higher than those of drug abuse more than 2 years(P ＜0.05).The proportion of preterm infants,low birth weight,neonatal asphyxia and NRDS of intravenous drug users were higher than those of oral drug users,the differences were significant (P ＜ 0.05).The red blood cellcount,aspartate amino transferase,white blood cellcount and alanine aminotransferase in the drug abusing group were higher than those in the control group,platelet and albumin were lower than those in the control group (P ＜0.05).A total of 30 neonates had the manifestations of neonatal withdrawal syndrome.In 105 cases of newborns,99 cases cured,6 cases died,the cure rate was 94.3％.The causes of death included 3 cases of NRDS complicated with pulmonary infection,1 case of severe intracranial hemorrhage,1 case of asphyxia,and 1 case of multiple organ failure.Conclusion Drug abuse can lead to the increase of premature birth rate,asphyxiation and NRDS.Late pregnant women with drug abuse can cause the incidence of neonatal withdrawal syndrome.

To prepare salvianolic acid phospholipid compound. With the compound of salvianolic acids and soybean phospholipid as the index, mono-factor experiment and orthogonal design experiment were conducted to screen its technical parameters. According to the results, the optimal preparation conditions of salvianolic acid phospholipid compound were that THF were taken as the reaction solvent, the concentration time was 3 h, the reactant concentration was 5 g x L(-1), the mass ratio of salvianolic acids and phospholipid was 1: 1.5, and the reaction temperature was 40 degrees C. The oil/water partition coefficient of the prepared salvianolic acid phospholipid compound significant increased in water and buffers with different pH values. The results of phase analysis such as DSC, XRD and FTIR indicated that salvianolic acids existed in phospholipid in an amorphous state.
