In order to promote the Shenqifuzheng injection (SQFZ) clinical medication safety, this study reevaluate on SQFZ post marketing safety study systematically. Including multi center large sample registration type safety monitoring research, the analysis based on national spontaneous reporting system data, the analysis based on the 20 national hospital information system data and literature research. Above the analysis, it suggests that SQFZ has good security. The more adverse drug reaction (ADR) as allergic reactions, mainly involved in the damage of skin, appendages and its systemic damage, serious person can appear allergic shock. ADR/E is more common in the elderly, may be related to medication (tumor) populations. Early warning analysis based on SRS data and literature research are of the view that "phlebitis" has a strong association with SQFZ used.

OBJECTIVE: To explore the effect of traditional Chinese herbal medicine (TCM) for nourishing liver and kidney, clearing meridians and removing toxic substances, on the neurobehavioral manifestations and the activity of the dopamine D2 receptor in rat with levodopa-induced dyskinesias (LID). METHODS: The rat model of Parkinson's disease (PD) was established by injecting 6-hydroxydopamine (6-OHDA) into right substantia nigra of brain, then, the model of LID in rat was produced by injecting levodopa (LD) and benserazide for 4 weeks. The rats were divided into normal control group, 4-week LD treated group, 4-week LD plus TCM treated group, 8-week LD treated group, and 8-week LD plus TCM treated group, and the effect of the TCM on neurobehavioral manifestations was observed. The radioligand binding assay (RLBA) and Scatchard drawing were used to measure the maximal binding capacity of receptor (Bmax) and equilibrium dissociation constant (KD) of the dopamine D2 receptor in corpora striatum. RESULTS: Compared with the 4-week LD treated group and 8-week LD treated group, TCM could decrease abnormal involuntary movement scores of the rats with LID; the RLBA revealed that the dopamine D2 receptor Bmax significantly increased (P<0.05, P<0.01) and the KD significantly decreased (P<0.05). CONCLUSION: TCM can improve the activity of the dopamine D2 receptor and relieve the symptoms of LID.

Objective To investigate the influence of epigallocatechin gallate ( EGCG)on reactive oxygen species (ROS) in mouse podocytes exposed to high glucose. Methods Mouse podocytes cultured in high glucose were exposed to different concentrations of EGCG (0.2, 10, 100 μmol/L) or α-tocopherol (0.2 μmol/L) for 6, 12, 24 hours. The viability of podocytes was detected by MTT. The intracellular formation of ROS was detected by confocal microscopy with fluorescent probe CM-H2DCFDA and was measured by fluorescence microscopy. RT-PCR was used to examine the expression of p22phox, p47phox and p67phox mRNA in cultured podocytes exposed to different concentrations of EGCG. Results Intracellular ROS generation was significantly higher in high glucose than that in control conditions (P<0.01). EGCG could significantly inhibit ROS induced by high glucose significantly (P<0.01). EGCG (100 μmol/L) led to an inhibition of the increased production of NADPH oxidase components of p22phox and p67phox mRNA in high glucose (P<0.05). The expression of p47phox mRNA in high glucose was inhibited by EGCG(0.2 μmol/L) and ot-tocopherol(0.2 μmol/L) (P<0.05). Conclusion EGCG can protect cultured mouse podocytes from injury of high glucose by inhibiting ROS formation.
