Objective:To improve the quality standard for Jinhuanglian oral liquid. Methods:The three herbs in the preparation, Honeysuckle, Scutellaria Baicalensis Georgir and St John's Wort, were identified by TLC qualitatively. The content of chlorogenic acid in Lonicerae Japonicae Flos was determined by HPLC. The chromatographic separation was carried out on a Promosil C18 (250 mm × 4. 6 mm,5 μm) column at 25℃. The mobile phase consisted of acetonitrile-0. 4% phosphoric acid (10 :90) with gradient elution at a flow rate of 1. 0 ml·min -1 , and the injection volume was 10μl. The detection wavelength was 327 nm. Results:The spots in TLC were clear without any interference. The linear range of chlorogenic acid was 5.325-170.400 μg·ml-1(r=0.9998). The average recovery was 97. 95% and the RSD was 2. 04%(n=6). Conclusion:The method is reliable and easy to operate,which can be used as the quality control method for Jinhuanglian oral liquid.

The whole process of consultation practice of clinical pharmacist for one case of pseudomonas aeruginosa intracranial in-fection was introduced and the role of clinical pharmacist in the anti-infective treatment was discussed. The three consultation recom-mendations of clinical pharmacist were accepted by doctors,and the patient's intracranial infection was effectively controlled and the pa-tient discharged soon. Pharmacists can help doctors develop anti-infective drug program through pharmacy thinking,horizontal thinking and risk thinking to guarantee the safety and effectiveness of patients' medication.

Objective:To observe and analyze the application effect and value of problem based learning (PBL) combined with team-based learning(TBL) in the teaching of New Drug Clinical Research. Methods:Postgraduate students were randomly divided in-to two groups(n=20):"PBL+ TBL" group and lecture based learning(LBL) group. After the end of the teaching,the teaching ef-fectiveness survey and theory test of the groups were performed,and the results were compared. Results:The combined teaching meth-od (PBL+TBL) could stimulate learning enthusiasm, improve learning efficiency, and enhance the abilities of self-study, literature retrieval and analyzing and solving problems. Totally 90% of students thought the new teaching method had good application value in clinical teaching. Furthermore,the excellent rate of the theory test scores in the combined teaching group was better than that in the traditional teaching group (P<0.05). Conclusion: PBL combined with TBL can overcome the disadvantages of traditional teaching method,which provides higher interest,improved ability of self-study as well as higher teaching quality of medical students. The meth-od is worthy of promotion in postgraduate teaching.

On-the-spot teaching method is one of teaching methods reflecting the principle of linking theory with practice, which is more and more widely used in the professional courses teaching in modern universities and colleges. Through the practice of on-the-spot teaching, students are able to more deeply understand the significance of Management of Military Medicinal Materials Supply so as to improve students' perceptual experience, stimulate their enthusiasm and initiative of learning and make up for the lack of experimental facilities to a certain extent.

Objective To investigate the effect and mechanism of emodin (EM) in renal interstitial fibrosis of unilateral ureteral obstruction (UUO) mice.Methods Male C57BL/6J mice were randomly divided into 4 groups,including sham operation group (n=8),UUO operation group (n=8),UUO operation+losartan (LST) group (n=8) and UUO operation+EM group (n=8).The mice in each group were ingested the suspensions by gavage for 14 days after surgery.Mice in UUO+LST and UUO+ EM groups were given 10 mg· kg-1· d-1 LST and 20 mg· kg-1 · d-1 EM,respectively.LST and EM were mixed with 0.5％ sodium carboxymethyl cellulose.Mice in sham group and UUO group were given 0.5％ sodium carboxymethyl cellulose.The mice were sacrificed at the 14th day.Interstitial fibrosis was observed by HE,Masson and PAS stain.Real-time PCR was used to detect LC3,Beclin-1 and mTOR mRNA.Protein expressions of TGF-β1,α-SMA,E-cadherin,LC3,Beclin-1,PI3K,p-Akt and mTOR were detected by Western blotting.The autophagy was observed with transmission electron microscopy in the renal tissue.Results Compared with sham mice,UUO mice at the 14th day displayed obvious renal fibrosis.Meanwhile,UUO mice had increased expressions of TGF-β1 and α-SMA (all P ＜ 0.01),and decreased expressions of E-cadherin (P ＜ 0.01).Their renal expressions of PI3K,p-Akt and mTOR were also raised (all P ＜ 0.01).Compared with those in UUO group,in UUO+LST group and UUO+EM group,expressions of autophagy protein LC3 and Beclin-1 were increased (all P ＜ 0.01),and the number of autophagic was increased.Additionally,expressions of TGF-β1 and α-SMA were reduced in UUO+LST group and UUO+EM group (all P ＜ 0.01),while the expression of E-cadherin was increased by emodin treatment (P＜ 0.05).And expressions of PI3K,p-Akt and mTOR were decreased in UUO + LST group and UUO + EM group (all P ＜ 0.05),meanwhile renal tissue fibrosis significantly reduced.Conclusions Emodin can promote autophagy,ameliorate renal interstitial fibrosis and protect renal function through PI3K/Akt/mTOR signaling pathway.

Objective: To establish the quality standard for Fuzheng capsules. Methods: TLC was adopted to identify Astragali Radix and Glycyrrhiza uralensis. The method validation for Fuzheng capsules was conducted by microbial limit test as described in the appendixes of Chinese Pharmacopeia (2015 edition). The content of epimedii in Epimedium brevicornu was determined by HPLC. The chromatographic separation was carried out on an Agilent TC-C18(2) (250 mm×4. 6 mm, 5 μm) column. The mobile phase consis-ted of acetonitrile-water( 30: 70) with gradient elution at a flow rate of 1. 0 ml·min-1,and the injection volume was 5 μl. The detec-tion wavelength was 270 nm. Results: The spots in TLC were clear without any interference. The methods of plating and direct inocu-lation could be used for the microbial limit test. The linear range was 0.101-1.008 μg (r =0.999 7). The average recovery was 99. 36% with the RSD of 0. 81% (n=6). Conclusion: The method is simple with high specificity and good repeatability, which can be used as the quality control method for Fuzheng capsules.
