Objective To investigate the effect of combination of ganglioside and hyperbaric oxygen on spastic cerebral palsy. Methods 128 infants with spastic cerebral palsy were divided into treatment group (n=70) and control group (n=58), who received ganglioside and hyperbaric oxygen or cytidine diphosphate choline. The infants in the treatment group were divided into young group (6～12 months, n=38) and old group (1～3 years, n=32) according to their age. They were assessed with Ashworth scale and Functional Independence Measure (FIM) before and 3 courses after treatment. Results The scores of Ashworth scale and FIM improved more in the treatment group than in the control group (P<0.01) after treatment, as well as in the young group than in the old group (P<0.01). Conclusion The combination of ganglioside and hyperbaric oxygen is effective on spasticity and activities of daily living in infants with spastic cerebral palsy. The younger the infants are, the more effective it is.

Objective To explore the dynamic change of serum leptin interleukin-6(IL-6),and interleukin-8(IL-8)during cerebral infarction,and to analyze the possible relationship between these factors and the severity of the disease.Method The levels of serum leptin,IL-6 and IL-8 were measured by radioimmunoassay in 60 patients with acute cerebral infarction,who were admitted to the hospital within 24 hours after stroke.Patients' neurologic impairment were evaluated by European Stroke Scale(ESS)at 1,3 and 7 days respectively after hospitalization.At the same time,another 30 normal adults were enrolled set as control group. Results The levels of serum Leptin,IL-8 in patients group after at 1 days,3 and 7 days were higher than those in the controls(P0.05).The ESS of these patients were 76.77?26.42,70.02?29.17,74.65?28.42 respectively,after 1,3 and 7 days.It shown that ESS simply correlated to the level of IL-8(P0.05).Statistic analysis was carried,but by using t test and linear correlation.(SPSS11.5 statistical package).Conclusion Leptin,IL-6 and IL-8 probably play a role in the inflammatory,reaction during acute cerebral infarction.The IL-8 may reflect the severity of the disease.

Objective To investigate the correlation between the plasma unconjugated bilirubin(UCB)and electrical activity of brain in term neonates with hyperbilirubinemia,and explore the parameters that possess the prognostic value and deduce a series of discriminant for prognostic judgment.Methods Thirty-two neonates with hyperbilirubinemia and 31 neonates without hyperbilirubinema(control group)were studied with standard EEG,and they were assessed for their neurological development in 3 and 6 months.A statistical method of Bayes Discriminant analysis was adopted to set up an equation with values of parameters of EEG,clinic datum and consequence.Stepdic and Dis-grim processes were used to pick out the parameters which had great significance for predicting the outcome of nervous system development.A series of discriminant was deduced for prognostic judgment and then cross validation was performed to assess the accuracy of the discriminant.Results 1.The standard EEG and brain electrical activity map records indicated that the hyperbilirubinemia group had longer maximum duration of interburst interval(IBI),longer mean duration of IBI,lower amplitude under all conditions,more anterior dysrhythmia(AD)in wake,and higher incidence of sleep-wake cycle disturbance.2.The plasma concentration of UCB was linear correlated with AD in wake.3.Gestational age,birth weight,plasma concentration of UCB,burst duration of IBI in trace alternate,amplitude in all sleep state,AD in wake,brief burst not in quiet sleep and sleep-wake cycle disturbance might play important roles in predicting the outcome of neonates with hyperbilirubinemia.Conclusions Cerebral electrical activity is an effective tool for predicting neurologic outcome of neonates with hyperbi-lirubinemia.Cerebral electrical activity and clinic data will provide a new method for accurately predicting neurological development and prognosis.

Objective To study the different ultrasonic features in patients of polycystic ovary syndrome (PCOS) with or without obesity based on body mass index (BMI), and to investigate whether certain hormonal factors correlate with ovarian morphology and blood flow, and to discuss the role of ultrasound combined with hormone test in the diagnosis of obese PCOS. Methods One hundred and five women with PCOS were recruited. Patients were divided into two groups according to BMI;obese PCOS group (OB-PCOS, n=32, BMI≥25 kg/m2) and non-obese PCOS (NOB-PCOS, n=73, BMI<25 kg/m2). The ultrasonic parameters of follicle number (FN), ovarian volume (Vol), resistance index (RI) of ovarian stromal blood, RI of uterine artery and serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), the ratio of luteinizing hormone and follicle-stimulating hormone (LH/FSH), progesterone (P), estradiol (E2), free testosterone (FT), prolactin (PRL), sex hormoe binding globulin (SHBG), fasting plasma glucose (FPG), fasting insulin (FINS), the extent of insulin resistance and hyperandrogenism (HOMA-IR) were measured and compared. The correlation of the ultrasonic parameters and hormonal factors were analyzed. Results The Vol of OB-PCOS group was significantly higher than NOB-PCOS group [(12.25±4.89) ml vs (10.73±2.30) ml, t=2.20, P < 0.05]. FN and uterine artery RI of OB-PCOS group had a rising trend and RI of ovarian interstitial was on a reducing trend compared with NOB-PCOS group. But the differences were not statistically significant. The levels of FINS and HOMA-IR in OB-PCOS group [(14.82±6.45) mU/L and (3.91±3.30)] were significantly higher than those in NOB-PCOS group [(8.04±4.57) mU/L and (1.64±1.20)] (t=4.87, 3.47, respectively, both P < 0.01). And FSH in NOB-PCOS group was significantly higher than OB-PCOS group [(5.95±1.91) U/L vs (4.65±1.88) U/L, t=-2.77, P<0.01]. In POCS patients, FN was significantly associated with LH/FSH (r=0.35, P<0.01), and FT (r=0.38, P<0.01). Vol was significantly associated with LH/FSH, BMI, HOMA-IR and FPG (r=0.27, P<0.05;r=0.25, P<0.05;r=0.40, P<0.01;r=0.32, P<0.01). RI of ovarian stromal blood flow was significantly associated with SHBG (r=0.28, P<0.05). In OB-POCS group, RI of uterine artery was significantly associated with PRL (r=-0.58, P < 0.05). Vol was significantly associated with HOMA-IR (r=0.47, P < 0.05). In NOB-POCS group, FN was significantly associated with LH/FSH (r=0.33, P<0.05), and FT (r=0. 56, P<0.05). Vol was significantly associated with FT (r=0.31, P < 0.05). Conclusion There are some differences in the ultrasound and endocrine parameters between obese and non-obese PCOS patients, and some correlations exist between them.

AIM To observe the long-term toxicities of reteplase(Ret). METHODS Rat was administrated by injection of vein on 14 consecutive days to macaca fasicular. RESULTS Ret 8.0 MIU?kg -1 to macaca fasicular did not show any toxicity. In 25.0 MIU?kg -1 and 80.0 MIU?kg -1 of doses, RBC, HGB and HCT of blood have significantly decreased. Feces of hidden blood test also showed positive response in some animals, meanwhile, Ret could reduce the content of plasma total protein. But these changes could have recovery in restoration period. In addition, in 8.0?25.0?80.0 MIU?kg -1 doses, Ret could significantly lengthen bleeding time and clotting time. The obvious toxic changes of coefficient and pathology in Ret 8.0?25.0?80.0 MIU?kg -1 groups were not found. CONCLUSION 8.0 MIU?kg -1 is a safety dosage by injection of vein. 25.0,80.0 MIU?kg -1 doses have certain toxic actions, such as anemia and bleeding, but these toxic effects were reversible.

This study is to establish physiologically based pharmacokinetic (PBPK) models of famitinib in rat and monkey, and then to predict the pharmacokinetics and tissue distribution of famitinib in human based on the PBPK models. According to published paper, previous studies and the chemical properties of famitinib predicted by ACD/ADME suite and SimCYP, the PBPK models of rat and monkey were established and optimized using GastroPlus. And then, the PBPK models were applied to predict the pharmacokinetic and tissue distribution of famitinib in human. The results showed that the PBPK models of rat and monkey can fit the observed data well, and the AUC0-∞, ratios of observed and calculated data in rat and monkey were 1.00 and 0.97, respectively. The AUC0-∞, ratios of observed and predicted data in human were 1.63 (rat to human) and 1.57 (monkey to human), respectively. The rat and monkey PBPK models of famitinib were well established, and the PBPK models were applied in predicting pharmacokinetic of famitinib in human successfully. Hence, the PBPK model of famitinib in human could be applied in future drug-drug interaction study.
