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 The aim of the present study was to evaluate the protective effects of momordica charantia polysaccharides(MCP)on depressive animal model induced by chronic social defeat stress(CSDS)and explore the underlying mechanisms.METHODS We established CSDS depressant mouse model and treated CSDS mice with MCP.Sucrose preference,forced swim test(FST)and social interaction test(SIT)were used to measure behaviors changes.We used ELISA,Q-PCR and western blot to test the levels of cytokines in the hippocampus. RESULTS The results showed that chronic administration of MCP(100,200 and 400 mg·kg-1)significantly prevented depressive-like behaviors in mice as assessed by social interaction (SIT), tail suspension (TST) and sucrose preference tests (SPT).It was showed that the elevation of proinflammatory cytokines(TNF-α,IL-6,and IL-β)concentra-tions,up-regulation of JNK3,c-Jun,and P-110β protein expressions in the hippocampus of CSDS model. Moreover,reduction activity of PI3K and phosphorylation level of protein kinase B(AKT)was also observed in the hippocampus of CSDS model.All above phenomenon were reversed after MCP intervened.Further-more,the protective effects of MCP on the CSDS mice were partly inhibited by the specific phosphati-dylinositol 3-kinase (PI3K)inhibitor, LY294002. CONCLUSION The protective effects of MCP against depressive-like effects in CSDS mice might reduce neuroinflammatory and involve in attenuation of JNK3/PI3K/AKT pathway in the hippocampus.

China Journal of Chinese Materia Medica 2008;33(4):416-419
OBJECTIVETo explore the character of inorganic elements in Polygonum multiflorum.
METHODThe contents of elements such as Al, B, Ba, Ca, Cu, Mn, Mg, Fe, Na, Ni, P, Se, Sr, Ti and Zn in nine P. multiflorum samples were determined by means of ICP-AEC. The results were used for the development of element distrubution diagram. The principal component analysis and one-way ANOVA of SPSS were applied for the study of characteristic elements in P. multiflorum.
RESULTThe contents of Al, Ca, K, Mg, Sr,Ti in wild P. multiflorum were remarkable higher than those in cultured P. multiflorum, and there was no significant difference between cultured and wild in the other elements. Five principal components which accounted for over 90% of the total variance were extracted from the original data. The analysis results show that Al, B, Ba, Fe, Na, Ni, Ti, Ca and Sr may be the characteristic elements in P. multiflorum. The element distrubution diagram of the sample from Tianyang was remarkable different comparing with the others.
CONCLUSIONThe principal component analysis could be used in data processing in inorganic elements.

OBJECTIVETo observe the changes in expression of microRNA-203 and P63 in human epidermal stem cells and KCs, and to investigate their effects and significance in the epidermal proliferation and differentiation.
METHODS(1) Five normal foreskin tissue specimens were collected from 5 patients by circumcision in Department of Urinary Surgery of the First Affiliated Hospital of Nanchang University from March to June in 2013. Then single cell suspension was obtained by separating epidermis with trypsin digestion method. The cells were divided into quick adherent cells and non-quick adherent cells by type IV collagen differential adherent method. The biological characteristics of cells were observed by inverted phase contrast microscope immediately after isolation and on post culture day (PCD) 3. The expression of CD29, keratin 19, keratin 1, and keratin 10 was identified by immunocytochemical staining. The expression of microRNA-203 and mRNA of P63 was determined by real-time fluorescent quantitative RT-PCR. The protein expression of P63 was determined by Western blotting. Data were processed with t test and Pearson correlation analysis.
RESULTS(1) Immediately after isolation, quick adherent cells were small, round, and dispersed uniformly. On PCD 3, the cells adhered firmly, and they grew in clones. Immediately after isolation, non-quick adherent cells appeared in different shapes and sizes, and dispersed unevenly. On PCD 3, the cells adhered precariously and did not show clonal growth. Quick adherent cells showed positive expression of CD29 and keratin 19, while non-quick adherent cells showed positive expression of keratin 1 and keratin 10. Quick adherent cells were identified as epidermal stem cells, and non-quick adherent cells were identified as KCs. (2)The expression level of microRNA-203 in epidermal stem cells (0.74 ± 0.20) was lower than that in KCs (3.66 ± 0.34, t =16.582, P <0.001). The mRNA expression level of P63 in epidermal stem cells (4. 16 ± 0.28) was higher than that in KCs (2.90 ± 0.39, t =5. 850, P =0.001). The protein expression level of P63 in epidermal stem cells (1.42 ± 0.05) was higher than that in KCs (0.73 ± 0.03, t =26.460, P <0. 001). (3) The expression level of microRNA-203 was in significantly negative correlation with the expression levels of mRNA and protein of P63 (with r values respectively - 0. 94 and -0.98 , P values below 0.05).
CONCLUSIONSThe expression levels of microRNA-203 and P63 in human epidermal stem cells and KCs were significantly different, which might be related to the different characteristics of proliferation and differentiation of the cells.

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.
