OBJECTIVE：To investigate the effects of pharmaceutical management intervention on the use of TCM injection in primary medical institutions. METHODS ：Twenty grass-roots health centers in Yichun city ，Jiangxi province were randomly selected. Relying on Department of Pharmacy and Health Services of the Municipal Health Committee and the Quality Control Center for Pharmacy Affairs of the City ，Yichun People ’s Hospital took the lead in establishing the prescription evaluation criteria for TCM injection ，training pharmaceutical service skills ，conducting special reviews on prescriptions/medical orders ，improving control measures ，obtaining relevant data of drug use in primary health centers by issuing questionnaires on the use of TCM injection and randomly selecting prescriptions/medical orders for comments. The relevant data without drug administration （before intervention）from Jan. to Jun. 2018 were taken as the non-intervention group ，and the relevant data with drug administration （after intervention）from Jan. to Jun. 2019 were taken as the intervention group. The use of TCM medicine injection ，DDDs，DDC and sequencing ratio were compared before and after intervention. At the same time ，the prescriptions/medical orders of TCM injections before（1 222 copies）and after （1005 copies）intervention were randomly selected for comment and the reasonable situations of the prescriptions/medical orders were compared before and after the intervention. RESULTS ：After intervention ，total amount ， consumption sum and DDDs of top 10 TCM injections in the list of amount were significantly decreased. The reasonable rate of prescriptions and medical orders was 48.04％ before intervention ， but increased to 70.65％ after intervention. Besides ， unreasonable situations before and after intervention all manifested as inappropriate indications. After the intervention ，the unreasonable rates of Xuesaitong powder for injection （lyophilized），Xueshuantong injection ，Xingnaojing injection （two specifications），Shengmai injection ，Xueshuantong for injection （lyophilized）and Qingkailing injection were significantly lower than before intevention （P＜0.05）. CONCLUSIONS ：Pharmaceutical administration intervention can reduce the total amount and the consumption sun of TCM injection in primary medical institutions ，and promote rational drug use in the clinic.

Objective Naringenin has a vast prospect of application because of its important biological activities .This study aims to explore the influence of different concentrations of naringenin on the growth of nasopharyngeal carcinoma CNE 2 cells and its ac-tion mechanisms. Methods Using the MTT method, we measured the effects of naringenin on the growth of CNE 2 cells after treated at the concentrations of 0, 0.005, 0.01, 0.02, 0.04, 0.06, 0.08, 0.1, 0.2, 0.4, and 0.8 mg/mL for 24, 48, and 72 hours.At 48 hours, we observed changes in the cycle of the cells treated with naringenin at 0, 0.02 and 0.04 mg/mL by flow cytometry, in the ap-optosis of the cells by Hochest 33258 staining and flow cytometry , in the level of reactive oxygen species ( ROS) in the cells by DCFH-DA staining, and in the mRNA expressions of C-fos, Bax and Bcl-2 by qPCR. Results Compared with the control group , naringe-nin at 0.02 and 0.04 mg/mL induced a low-level rise of ROS in the CNE2 cells (MFI:5186 ±183.50 and 5508 ±155.37, P<0.05), up-regulated the expression of C-fos (P<0.05 or P<0.01), and promoted the proliferation of the cells .However, naringenin at relatively high concentrations of 0.2 and 0.4 mg/mL significantly elevated the level of ROS (MFI:10758 ±179.82 and 11241 ±1 114.45, P<0.01), up-regulated the expression of Bax (P<0.01), down-regulated that of Bcl-2 (P <0.01), induced the apoptosis (P<0.01 ) and suppressed the proliferation of CNE 2 cells. Conclusion Within a concentration range of 0.005-0.8 mg/mL, naringenin may have two-way effects on the growth of CNE2 cells, a carcinogenic effect at a relatively low dose and a good anticancer effect at a relatively high dose .

OBJECTIVE：To investigate the contents of 5 kinds of heavy metal as copper （Cu），arsenic（As），cadmium （Cd），mercury（Hg）and lead （Pb）in Yougui pills ，and to evaluate its safety risk. METHODS ：Using yttrium （89Y），indium （115In）and bismuth （209bi）as internal standard ，the contents of each element were determined by ICP-MS. ICP-MS condition included that atomization gas flow rate was 0.95 L/min，auxiliary gas flow rate was 1.2 L/min，plasma gas （argon）flow rate was 18 L/min，pump speed was 30 r/min. RF power of inductively coupled plasma was 1 200 W，the voltage in simulation stage was 1 750 V，the voltage in pulse stage was 1 300 V，the voltage of deflection device was －12 V，and the detector was in analog and pulse dual-mode. The determination methods of various elements were investigated ，and 45 batches of marketed Yougui pills were determined. Hazard index （HI）was used to analyze the non-carcinogenic risk of each element and calculate the maximum residual limit（MRL）of each element. RESULTS ：The linear range of Cu ，As，Cd，Hg and Pb ranged from 10-200，1-50，0.4-30，0.2-6 and 2-100 μg/L（all r＞0.999 0），respectively. The limits of quantitation were 0.67，0.23，0.20，0.07，0.27 μg/L. The limits of detection were 0.20，0.07，0.06，0.02，0.08 μg/L. RSDs of precision，stability and reproducibility tests were all lower than 3.5％ （n＝6 or n＝5）. Average recoveries were 92.96％-100.89％（RSD＝2.23％-3.62％，n＝3）. Average contents of Cu ，As，Cd，Hg and Pb in 45 batches of Yougui pills were 2.72，0.28，0.07，0.05，0.62 mg/kg，and superimposed HI of each element was less than 1. The contents of 5 kinds of heavy metals in Yougui pills were lower than the proposed MRL （MRL of Cu ，As，Cd，Hg and Pb were 20，2，1，0.2，5 mg/kg or 111.11，4.44，2.22，1.48，8.89 mg/kg respectively ）. CONCLUSIONS ：Established method can be used for the determination of content of 5 kinds of heavy metal in Yougui pills ；the heavy metal pollution rate of marketed Yougui pills is low and the safety risk is small.

Toimprovethesensitivity,aCuOnanoparticledopedinmolecularlyimprintedpolymer(MIP)film for the determination of phenobarbital was prepared by using methacrylic acid as functional monomers, ethylene glycol maleic rosinate acrylate as a cross linking agent by thermal polymerization method. The electrochemical properties of the nano-doped sensor were investigated using cyclic voltammetry ( CV ) , differential pulse voltammetry ( DPV ) , electrochemical impedance spectroscopy ( EIS ) and chrono-amperometry ( CA) . The chemical structures and morphologies of the imprinted films were characterized using Fourier transform infrared spectroscopy and scanning electron microscopy. The results indicated that the sensors response value of peak current showed a linear dependence on the phenobarbital concentration in the ranges of 1. 2 × 10-7-1. 5 × 10-4 mol/L of phenobarbital. ( Linear regression coefficient=0. 9984 ) with the detection limit ( S/N=3 ) of 8. 2 × 10-9 mmol/L. The prepared sensor was successfully applied to the determination of phenobarbital in practical samples with recovery ranging from 96 . 5% to 103 . 0%.

Objective:To investigate the changes of cyclooxygenase-2 (COX-2) expression in the spinal cord dorsal horn atfer intrathecal a speciifc p38MAPK inhibitor-SB203580 on neuropathic pain in rats induced by chronic constrictive injury (CCI) to the sciatic nerve. Methods:Twenty-four male SD rats atfer intrathecal catheter placement were randomly divided into 4 groups:a sham group with sham surgery, the neuropathic pain model of a NS group, a DMSO group and an SB group were established by CCI to sciatic nerve. NS or DMSO or SB203580 was injected IT NS or 2%DMSO or SB203580 twice a day for 5 consecutive days starting at 6th day when the model of chronic constrictive injury was established. Mechanical stimuli were measured before the surgery and on 1st, 3rd, 5th, 7th, 9th, and 11th day atfer the surgery. hTen all rats were sacriifced and the lumbar segment of spinal cord was removed to determine the COX-2 expression in the dorsal horn by immunocytochemistry. Results:Day 1 to 11 after the surgery, the threshold to mechanical on the surgery side was signiifcantly lower in the NS group and the DMSO group than in the sham group. Day 7 to 11 atfer the sugery, the threshold to mechanical on the surgery side was signiifcantly lower in the SB group than in the NS group and the DMSO group. hTe expression of spinal COX-2 was higher in the NS group and the DMSO group than in the sham group, but lower in the SB group than in NS group and the DMSO group. Conclusion:Intrathecal administration of SB203580 has signiifcant analgesic effect in the CCI rat model. Expression of COX-2 is signiifcantly reduced when p38MAPK is inhibited by intrathecal SB203580, and p38MAPK stimulation is essential for COX-2 expression.
