Objective To evaluate the association between C-reactive protein (CRP) blood levels and specific survival time of non-small cell lung cancer (NSCLC) patients treated with chemotherapy.Methods Data from 96 advanced (stage ⅢB/Ⅳ) NSCLC patients were analyzed.All patients were divided into two groups based on the enrolled time as follows the initial treatment group (48 cases) and retreatment group (48 cases).According to 0.6 mg/L and 7.3 mg/L of CRP which were the 1/3 and 2/3 of CRP concentrations,respectively,the 96 patients were divided into low,intermediate and high groups.Kaplan-Meier and Cox proportional-hazard models were used to evaluate the relationship between the CRP level and survival time.Results After adjusting for age,sex,smoking history,histological type and stage of lung cancer,a significant relationship between CRP and survival time was observed (P ＜ 0.05).Such significant differences of survival time were also observed in both of the adenocarcinoma (P ＜ 0.001) and squamous with poorly differentiated (P =0.032) subtypes.On stratification analysis by chemotherapy status,the circulating CRP level in retreatment group was correlated well with survival time (P ＜ 0.001).However,the influence of circulating CRP levels on survival time in initial group did not reach statistical significance (P =0.296).For all patients,the hazard ratio with high CRP levels for NSCLC-specific survival was 1.15 (95 ％ CI 0.82-1.61) compared with that of low CRP levels.The hazard ratio for the initial treatment group and retreatment group were 0.52 (95 ％ CI 0.16-1.74) and 1.77 (95 ％ CI 0.73-4.26),respectively.Patients with high circulating CRP level also responded poorly to chemotherapy.Conclusion A high level of circulating CRP is associated with an inferior response and survival outcome in NSCLC patients treated with chemotherapy.

Objective To explore the relevance of high density lipoprotein cholesterol (HDL-C) level and resistance of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in advanced non-small cell lung cancer (NSCLC).Methods In a total of 87 NSCLC patients harboring EGFR mutation treated with EGFR-TKI, the correlations of pre-treatment levels of soluble HDL-C between efficacy and resistance of EGFR-TKI were analyzed by Kaplan-Meier method and Cox proportional hazard model.Results Patients with normal HDL-C (≥0.94 mmol/L) had a better disease control rate (DCR) than those with low HDL-C (＜0.94 mmol/L) [94.5 ％ (52/55) vs 65.7 ％ (21/32), P ＜ 0.001].The results of univariate analysis showed that patients with normal HDL-C had longer progress free survival (PFS) (HR =0.27, 95 ％ CI 0.164-0.444, P ＜ 0.001).The results of multivariate Cox proportional hazard model analysis with sex, pathologic histology, smoking history and mutation type showed that only HDL-C group had a significant difference (P ＜ 0.001).The same results were showed when stratified by sex and smoking history (female: P ＜ 0.001, male: P =0.002;Smoker: P ＜ 0.001, non-smoker: P =0.014).Conclusion Normal pre-treatment serum levels of HDL-C are associated with a better outcome and longer progression-free survival in NSCLC patients treated with EGFR-TKI, which may be a predictive marker for a better response.

To investigate the effect of estrogen receptor (ER) agonist 17β-estradiol and G protein-coupled estrogen receptor 1 (GPER) agonist fulvestrant on masangial cell fibrogenesis under protein kinase C (PKC),we quantified type Ⅳ collagen (COL4A1),fibronectin (FN1),connective tissue growth factor (CTGF) and transforming growth factor-β1 (TGFβ1) gene transcription and semi-quantified phosphorylation of Akt signal upon Phorbol 12-myristate 13-acetate stimulation (which increased COL4A1,FN1,CTGF and TGFβ1 gene transcription to 2.5-0.5,1.4 ±0.2,26 ± 11 and 1.9 ±0.3 times compared with baseline,P ＜0.05) when incubated with the two drugs.It was found that 17β-estradiol and fulvestrant down-regulated COL4A1,FN1,CTGF and TGFβ1 genes transcription (P ＜0.05) and Akt signaling under PKC activation via ER and GPER.ER and GPER agonists are beneficial in protecting the mesangial cells from fibrogenic stimuli by inhibiting PKC signaling and excessive extracellular matrix production.

OBJECTIVE:To provide reference for the establishment of clinical skills evaluation system in students majored in clinical pharmacy and pharmacy of China. METHODS:Retrieved from pharmacy OSCE literatures and the related websites,phar-macy OSCE contents and evaluation in the United States,the United Kingdom,Canada,Japan,Malaysia and other countries were introduced to provide suggestions for clinical skills evaluation system in students majored in clinical pharmacy and pharmacy of Chi-na. RESULTS & CONCLUSIONS:OSCE had widely applied in medicine,nursing and other professional clinical skills,the United States,the United Kingdom and other countries had applied OSCE into pharmacy,and confirmed its important role in assessment of clinical competence in pharmacy students. There was no uniform standard in OSCE,and OSCE examinations were slightly different in different countries and different schools. Pharmacy OSCE usually based on school courses such as pharmacotherapy,clinical pharmacokinetics,medicine information,pharmaceutical care,doctor-patient communication,identification and solving ability of clinical drug-related issues. Numerous college of pharmacy in domestic colleges and universities has added the practice-based cours-es,but evaluation system and assessment methods are poor. Almost no OSCE is applied for the assessment of pharmacy students. OSCE has short application time in pharmacy education and relatively less study,therefore,pharmacy OSCE in foreign countries should be learnt to assess clinical skills of pharmacy students,establish and improve the pharmacy OSCE that is suitable for China by combining with the pharmacy education status.

A liquid chromatography-quadrupole-time-of-flight mass spectrometer(LC-Q/TOF-MS) based urinary metabolomic approach was employed to assess the toxicity-alleviation effect of Huangqi oral solution(HOs) on cisplatin-exposed rats and explore its possible mechanisms. Rat toxicity model was developed by multiple intraperitoneal injection of low-dose cisplatin, while HOs was orally administrated to rats simultaneously for 16 consecutive days to attenuate or reduce the cisplatin-induced toxicity. 24-hour urine samples on day 18 were collected and analyzed using LC-Q/TOF-MS to obtain the dataset of urinary metabolites. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed to assess the quality of the dataset and screen the potential toxicity-alleviation biomarkers. The serum level of rat creatinine and urea nitrogen on day 20 was determined, and the results showed that successive administration of HOs significantly reduced the cisplatin-induced increase of creatinine and urea nitrogen. PCA cluster analysis clearly demonstrated that HOs could partly improve the CDDP-induced abnormality of metabolic profiling. 35 urinary metabolites were finally screened as the potential biomarkers associated with the toxicity-attenuation effect of HOs, according to the combination of the analysis results of OPLS-DA, t-test and fold change analysis. Further metabolic pathway analysis revealed that HOs could restore the metabolic disorders of amino acid, energy and nucleotide, thereby exerted its toxicity-alleviation effect.

Objective To study the time-toxicity and dose-toxicity relationship of hepatotoxicity induced by Paracetamol Tablets (PT),Compound Paracetamol and Amantadine Hydrochloride Tablets (CPAH),Compound Dextromethorphan Hydrobromide Tablets (CDH),and Chaiqin Qingning Capsules (CQC) with single dose in mice.Methods In the Time-Toxicity relationship study,Kunming mice were randomly divided into control,PT,CPAH,CDH,and CQC group,and mice of.each drug administration group were randomly divided into nine subgroups according to the time (1,2,4,8,12,24,48,72 and 96 h after administration) of blood collection.The acetaminophen contents in PT,CPAH,and CDH groups were 425.98 mg/kg,and the dose of CQC group was 3 680.50 mg/kg.In the Dosage-Time relationship study,mice were randomly divided into control,PT,CPAH,CDH,and CQC high,medium and low dose group.The acetaminophen contents of high,medium,and low dose were 266.24,425.98,and 681.57 mg/kg in PT,CPAH,and CDH group,and the dose of CQC group was 1437.70,2300.31,and 3680.50 mg/kg,10 mice in each group,sex in half.Blood was collected 12 h after administration.Animal behavior was observed every day,blood and organs were collected at the corresponding time points,serum alanine aminotransferase (ALT),aspartate aminotransferase (AST),and alkaline phosphatase (ALP) level were detected,and the organs index of spleen and thymus,liver were calculated.Results There were no significant changes of ALT,AST,ALP,and organs index after once ig administration of CQC at dosage of 1437.70 mg/kg to 3680.50 mg/kg in mice.The study on time-toxicity relationship indicated that,after once administration of PT,CPAH,and CDH at 425.98 mg/kg,mice showed toxic symptom such as hypokinesia,dry hair and so on,12 h was the most obvious,24 ～ 72 h disappeared.The level of ALT,AST,and ALP in serum increased and reached to the peak at 12 h and then restored near normality after 72,24,and 24 h in PT,CPAH,and CDH group.Their organ index of liver,spleen and thymus all had no significant changes.The study on the dosage-toxicity relationship indicated that,there were no significant changes of animal behavior,ALT,AST,ALP,and organs index after once ig administration of PT,CPAH,and CDH at 266.24 mg/kg.Obvious liver injury can be induced by the three drugs with dosage of 425.98 to 681.57 mg/kg and the level of ALT,AST,and ALP increased significantly with the increase of dosage.Their liver index increased significantly with dosage of 681.57 mg/kg,but the organs index of spleen,thymus had no significant changes.Conclusion There was no hepatotoxicity after once ig administration of CQC with dosage of 3680.50 mg/kg in mice.Mice were once ig administration ofPT,CPAH,and CDH with a large dose,may induce acute liver injury and show obvious time-toxicity and dose-toxicity relationships.
