The ongoing health reform encourages pharmacists of public hospitals to change their traditional role positioning to satisfy patients’urgent needs in medical dosage guidance.This calls for greater capacity of hospital pharmacy services.Pharmaceutical consultation constitutes a major means of quality service of pharmacists for the people.The paper introduced the standard of establishing the pharmaceutical consultation center and the content of assessment system which are jointly worked out by Beijing Municipal Hospital Authority and the hospitals under the administration of the Beijing Municipal Government,and share the practice & effect in assessing and improving their performance.

Objective To explore whether fluid-attenuated inversion recovery can be used to estimate the onset time of acute ischemic stroke (ALS) based on the analysis of signal strength through the fluid-attenuated inversion-recov?ery (FLAIR)and volume of interest (ROI) in ALS patients with known time of onset. Method Forty-seven AIS patients who met the inclusion criteria were recruited from Baotou Central Hospital, Department of Neurology from January 2011 to December 2012. The patients had stroke onset within 12 hours and completed MRI scan including diffusion-weighted imaging DWI, apparent diffusion and coefficient ADC FLAIR. Based on MRI findings, patients were divided into, three groups:0~180 min, 180~360 min and 360~720 min groups. Signal strength values of the DWI、FLAIR and ADC in ipsi?lateral and contralateral sides were measured. Result There was a significant difference in the FLAIR signal strength among these three groups.The FLAIR signal strength was significantly lower in 0~180 min and 180~360 min groups than in 360-720 min. FLAIR positive rate was 16.7%, 62.5%, and 70.6% in 0~180 min, 180~360 min and 360~729 min groups, respectively. Conclusion FLAIR positive rate gradually increases as the onset prolongs. Thus, lower FLAIR posi?tive rate indicates shorter onset time of AIS, which can be used to assist acute intravenous thrombolytic therapy.

Objective To explore the expression of the nerve growth factor receptors p75 (p75NGFR) in human bladder carcinoma samples, and the effects of hypoxia on the expression of p75NGFR in human bladder cancer ceils. Methods The expression of p75NGFR in 107 bladder cancer and lymph node specimens were immunohistochemically investigated. The expression of p75NGFR in bladder cancer cell line (T24) was assessed by immunocytochemistry, and reverse tran-scription-PCR in the Normoxic Condition (air, 5%CO2) and in hypoxia condition(10%O2, 5%CO2, 85%N2). Results p75NGFR expressed in 46 of 107(43.0%) tumor samples. There was no signifi-cant correlation between p75NGFR and the factors such as gender, age, extent of the tumors, and pathologic grading(P0.05), p75NGFR was expressed in examined cell line T24, and also expressed in 5 of 24 bladder tumors in metastasized lymph node specimens. Hypoxia markedly down-regulated the expression of p75NGFR of T24 cell line at third day. Conclusions It is suggested that p75NGFR is expressed less in lymph node metastasis. Hypoxia markedly inhibited expression of p75NGFR of T24 cell lines.

Objective:To analyze the impact of previous exposure to macrolide, quinolones and nitroimidazole antibiotics on eradication rate of bismuth quadruple therapy (BQT) in newly diagnosed patients with Helicobacter pylori( H. pylori). Methods:A total of 469 patients with H. pylori initially treated at the Third Hospital of Peking University from September 2017 to August 2020 were retrospectively recruited. The therapeutic regimens were BQT containing clarithromycin/levofloxacin/metronidazole recommended by Chinese guidelines. Clinical data were collected, including general demographic data, exposure history of antibiotics, CYP2C16 metabolic pattern, endoscopic diagnosis, bacterial density, H.pylori resistance, eradication results, etc. Univariate analysis, Chi-square test, Fisher exact probability test, Kruskal-Wallis H test and Logistic regression model were used as statistical methods. Results:Among different eradication therapies, univariate and multivariate analyses suggested that previous exposure to macrolides ( OR=3.37,95 %CI 1.04-10.98, P<0.05) was relevant to the decreased eradication rate of BQT containing clarithromycin. This may be due to increased resistance to clarithromycin ( OR=6.12,95 %CI 3.99-9.40, P<0.01).The previous exposure to quinolones ( OR=3.65, 95 %CI 1.27-10.49, P<0.05) was relevant to the decreased eradication rate of BQT containing levofloxacin, which was probably explained by the increased resistance to levofloxacin ( OR=2.50, 95 %CI 1.69-3.71, P<0.01). But the previous history of nitroimidazole did not impact the efficacy of BQT containing metronidazole. Conclusions:In patients newly diagnosed with H.pylori infection, the previous exposure to macrolide or quinolones antibiotics is related to lower eradiation rates of H. pylori. Although the exposure to nitroimidazole also indicates drug resistance to metronidazole, the clinical efficacy of BQT with metronidazole 400 mg four times a day is not affected.

BACKGROUND: Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens. METHODS: This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables. RESULTS: As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups. CONCLUSION: The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.
