Objective To investigate the effect of erythropoietin(EPO)as a brain-protective factor and inflammatory cytokines in the pathogenesis of cerebral palsy(CP).Methods Serum samples from 31 CP patients,37 neonates with CP risk factors such as hypoxic-ischemic injury and/or perinatal infection,and 20 controls of neonates or children were obtained respectively.EPO,tumor necrosis factor(TNF)-α and interleukin(IL)-6 levels were measured with the enzyme-linked immunosorbent assay double sandwich method(ABC-ELISA).Results The serum EPO level of neonatal patients was higher than that of controls or CP group(P<0.01),but there was no significant difference between CP group and controls.The serum TNF-α and IL-6 levels of CP and neonatal patients were higher than that in controls(P<0.01).The serum TNF-α level of CP group was higher than that of neonatal patients(P<0.05).There was no significant difference between CP group and neonatal patients in serum IL-6 level.Conclusion The inflammatory responses mediated by proinflammatory cytokines may play a role in the pathogenesis of cerebral palsy.

Aim To determine potential biomarkers contributed to occurrence, development and recovery of ethanol-induced liver injury in rat and elucidate hepatoprotective effect of Yin Chen Hao Tang based on metabonomic investigation. Methods A UPLC-Q-TOF/MS based metabonomic method was developed for investigating trajectory change and inter-relationship of urinary metabolome of rats with different treatments. Results Four potential biomarkers were determined which contributed to occurrence, development and recovery of ethanol-induced liver injury in rat, and Yin Chen Hao Tang could significantly recover trajectory change in disorder. Conclusion The developed method was successfully applied to investigate ethanol-induced liver injury in rat, and also hepatoprotective effect of Yin Chen Hao Tang was elucidated.

OBJECTIVE: To explore the effects of Salvia miltiorrhiza on renal morphology and renal function of rats with streptozotocin diabetes. METHODS: Thirty male Wistar rats were randomly divided into three groups, which were normal control group, untreated group and Salvia miltiorrhiza-treated group. Diabetic nephropathy was induced in rats of the last two groups by intraperitoneal injection of streptozotocin after unilateral nephrectomy. Then the rats in the normal control and untreated groups were fed with normal saline while those in the Salvia miltiorrhiza-treated group were fed Salvia miltiorrhiza preparation for 8 weeks. The glomerular volume (VG), kidney-to-body weight ratio (KW/BW), urinary albumin excretion rate (UAER) and creatinine clearance (Ccr) were observed. The expression levels of transforming growth factor-beta1 (TGF-beta1), connective tissue growth factor (CTGF), fibronectin (FN) and plasminogen activator inhibitor-1 (PAI-1) were detected by real-time quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) at the end of the experiment. RESULTS: UAER, Ccr, VG and KW/BW ratio were significantly higher in the untreated group than those in the normal control group (P<0.05). The expression levels of TGF-beta1, CTGF, PAI-1 and FN in the untreated group were also significantly higher as compared with those in the normal control group (P<0.05). UAER, Ccr, VG, KW/BW ratio and the levels of TGF-beta1, CTGF, PAI-1 and FN in the Salvia miltiorrhiza-treated group were obviously lower than those in the untreated group (P<0.05). CONCLUSION: Salvia miltiorrhiza can protect rats with streptozotocin diabetes from diabetic nephropathy by suppressing the over-expressions of TGF-beta1, CTGF, PAI-1 and FN in renal cortex.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).
METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.
RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.
CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.

The tissue-specific and MeJA-induced transcriptional levels of BcUGT3 and BcUGT6 in Bupleurum chinense were analyzed in the present study. The transcriptional levels of BcUGT3 in root, leaf, flower and fruit were similar and they all were higher than those in stem. The transcriptional level of BcUGT6 was the highest in leaf and the lowest in flower among in all tested tissues. With non-treated adventitious roots as control, BcUGT6's transcriptional levels were elevated to nearly 2 folds for 2 h, 8 h, 24 h, 2 d and 4 d in MeJA-treated adventitious roots of B. chinense. It showed that the transcriptional level of BcUGT6 was slightly affected by MeJA. While, BcUGT3's transcriptional levels were gradually elevated, and till 4 d after MeJA treatment, the expression level was about 7 folds than that of non-treated control. Using pET-28a (+), the expressions of two genes was investigated. Induced by IPTG, the target proteins were expressed in E. coli and then purified. All the results obtained in the present study will be helpful for follow-up bio-function analysis of BcUGT3 and BcUGT6.

The effect of cholesterol ester transfer protein(CETP) on SR-B1 mRNA expression in mouse liver was investigated.The results demonstrated that CETP transgenic mice showed lower serum total cholesterol and high density lipoprotein-cholesterol levels but higher total cholesterol and cholesterol ester content in liver when compared with wild type mice(P<0.05).The expression of SR-B1 mRNA in liver of CETP transgenic mice was significantly lower as compared with the control group(P<0.05).
