OBJECTIVETo discuss the protective effect of alkaloids from Piper longum (PLA) in rat dopaminergic neuron injury of 6-OHDA-induced Parkinson's disease and its possible mechanism.
METHODThe rat PD model was established by injecting 6-OHDA into the unilateral striatum with a brain solid positioner. The PD rats were divided into the PLA group (50 mg x kg(-1) x d(-1)), the madorpa group (50 mg x kg(-1) x d(-1)) and the model group, with 15 rats in each group. All of the rats were orally given drugs once a day for 6 weeks. Meanwhile, other 15 rats were randomly selected as the sham operation group, and only injected with normal saline in the unilateral striatum. The behavioral changes were observed with the apomorphine (APO)-induced rotation and rotary rod tests. The number of tyrosine hydroxylase (TH)-positive cells in rat substantia nigra and the density of TH-positive fibers in striatum were detected by tyrosine hydroxylase immunohistochemistry. The content of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH), catalase (CAT), malondialdehyde (MDA), nitric oxide (NO) and nitric oxide synthase (NOS) in rat substantia nigra and striatum were measured by the spectrophotometric method.
RESULTAfter being induced by APO, PD rats showed obvious rotation behaviors, with decreased time stay on rotary rod and significant reduction in the number of TH-positive cells in sustantia nigra and the density of TH-positive fibers in striatum. The activities of SOD, GSH-Px, CAT, the content of GSH and the total antioxidant capacity significantly decreased, whereas the activities of NOS and the content of MDA, NO significantly increased. PLA could significantly improve the behavioral abnormality of PD rats and increase the number of TH-positive cells in sustantia nigra and the density of TH-positive fibers in striatum. It could up-regulate the activities of SOD, GSH-Px, CAT, the content of GSH and the total antioxidant capacity, and decrease the content of NOS and the content of MDA, NO.
CONCLUSIONAlkaloids from P. longum shows the protective effect in substantia nigra cells of 6-OHDA-induced PD model rats. Its mechanism may be related with their antioxidant activity.

Research on polymer impurities has always been important in the quality control of cephalosporins. Research on polymers in cephalosporins that lack active amino groups on the C-7 side chain has not been reported. Therefore, our study used cefazolin sodium, which is widely used in the clinic, as an example. The polymer in cefazolin sodium and its product "cefazolin sodium pentahydrate for injection" was analyzed by column switching liquid chromatography-high resolution mass spectrometry. Two polymer impurity peaks were detected and the possible structures of these polymers were suggested. Through two-dimensional liquid chromatography, the chromatographic peaks following Sephadex gel chromatography and high-performance gel chromatography were compared to those obtained by reverse high-performance liquid chromatography (HPLC) for cefazolin sodium as reported in the Chinese Pharmacopoeia. The HPLC method proves more suitable for polymer detection than Sephadex gel chromatography and high-performance gel chromatography. The method of polymer detection for cefazolin sodium was established using the method of related substances HPLC as described in the Chinese Pharmacopoeia.

OBJECTIVETo explore the relationship of vascular endothelial growth factor C (VEGF-C) and collagen triple helix repeat containing 1 (CTHRC1) expression with the carcinogenesis and prognosis of rectal cancer.
METHODSCancer tissue samples from 120 rectal cancer patients confirmed by pathology in the People's Hospital of Yichun City from September 2005 to September 2010 were included in the study. Expressions of CTHRC1 and VEGF-C were examined by immunohistochemistry and their correlations with clinicopathological features and prognosis were analyzed.
RESULTSThe expression of VEGF-C was positively correlated with tumor size (r=0.943), TNM stages (r=0.784) and tumor differentiation (r=0.773) (all P<0.05). Similarly, the expression of CTRHC1 was also positively correlated with tumor size (r=0.829), TNM stages (r=0.632) and tumor differentiation (r=0.532) (all P<0.05). Rectal cancer patients with low expression of VEGF-C and CTHRC1 had significantly longer survival than those with high expression of VEGF-C and CTHRC1 [(40.0±1.3) vs. (35.4±0.5) months, P<0.01, (39.0±0.5) vs. (35.0±0.5) months, P=0.014].
CONCLUSIONVEGF-C and CTHRC1 may synergistically promote the invasion and metastasis of human rectal cancer, and provide evidence in predicting the prognosis of patients.
