Objective To analyze the correlation between neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR) in peripheral blood and the therapeutic effect and prognosis of patients with advanced lung adenocarcinoma treated with tyrosine-kinase inhibitors.Methods Retrospective analysis was utilized to measure the clinical pathological characteristics and follow-up data of 40 cases with advanced lung adenocarcinoma definitely diagnosed by pathology.Correlation analysis was performed by Spearman test,and comparison of the sample rate was measured by the chi square test.Survival analysis was performed by Kaplan-Meier method,Log-rank test was used to compare patients survival difference among different groups.COX regression model was utilized to analyze the prognostic factors of patients with lung cancer.Results Through the ROC curve,the optimal cut-off points of NLR and PLR were calculated to be 3.74 and 205.1 respectively.In NLR<3.74 group,objective response rate(ORR),the median progression-free survival(PFS) and the median overall survival(OS) were 86.9%(20/23),9.02 months and 12.37 months respectively.In NLR ≥3.74 group,ORR,the median PFS and the median OS was ORR were 35.2%(6/17),3.15 months and 5.12 months respectively.Compared with NLR ≥ 3.74 group,NLR<3.74 group had a higher ORR(P=0.036),PFS(P=0.011) and OS(P=0.021),the difference was statistically significant.In PLR<205.1 group,ORR,the median PFS and the median OS was ORR were 85.7%(18/21),9.67 months and 14.35 months respectively.In PLR ≥ 205.1 group,ORR,the median PFS and the median OS was ORR were 42.1%(8/19),3.21 months and 9.25 months respectively.Compared with group PLR ≥ 205.1,PLR<205.1 group had a higher ORR(P=0.045) and PFS(P=0.018),the difference was statistically significant.COX multivariate analysis showed that NLR was an independent prognostic factor for PFS(RR=1.091,95%CI:1.004-1.185,P=0.039) and OS(RR=0.986,95%CI:0.932-1.148,P=0.021).PLR was an independent prognostic indicator of PFS(RR=1.100,95%CI:0.996-1.005,P=0.024).Conclusion NLR and PLR may be independent prognostic factors in patients with advanced lung adenocarcinoma.

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.

Objective To study the dose-time-toxicity relationship of hepatotoxicity in mice with multiple administration of Paracetamol Tablets (PT),Compound Paracetamol and Amantadine Hydrochloride Tablets (CPAH),Compound Dextromethorphan Hydrobromide Tablets (CDH),and Chaiqin Qingning capsules (CQC).Methods Mice were randomly divided into control,PT,CPAH,CDH,and CQC high,medium,and low dose groups.The acetaminophen contents of high,medium,and low doses were 266.24,425.98,and 681.57 mg/kg in PT,CPAH,and CDH groups,and the doses of CQC group were 1437.70,2300.31,and 3 680.50 mg/kg,ig administration,once daily for 5 d.General state and toxicity of mice were observed.The changes of ALT,AST,AKP,TBIL,and ALB levels in serum and organ indexes of liver,spleen,thymus,and kidney were tested on day 1,3,7,11,and 14 after multiple administration.Results CQC with the dosage range of 1 437.70-3 680.50 mg/kg to mice within 14 d,has not yet induced the increase of AST,ALT,AKP,TBIL,and ALB levels and changes of organ indexes of liver,thymus spleen,and kidney compared with normal control (P ＞ 0.05).PT,CPAH,and CDH with repeated dose of 425.98-681.57 mg/kg could induce significant increase of the levels ofALT,AST,AKP,and TBIL which reached the peak on day 1 (P ＜ 0.05),and then gradually decreased on day 3-14.The level of ALB significant decreased on day 1-11 (P ＜ 0.05),and then gradually recovered on day 11-14.The liver index significant increased on day 1-3 (P ＜ 0.05),and recovered on day 7-14.Conclusion Multiple administration of CQC could not induce liver injury in mice within 14 d,while multiple administration ofPT,CPAH,and CDH could induce hepatotocixity in mice with a certain dose,and show an obvious dose-time-toxicity relationship.

The objective of the present study was to establish a method based on principal component analysis (PCA) for the study of transdermal delivery of Chinese medicinal formulae, and to choose the best penetration enhancers for Qingfei Xiaocuo gel depend on this method. Using improved Franz type diffusion cell and excised rat skin in vitro as transdermal barrier, the receptive solution fingerprint was established by HPLC, harvesting the areas of the common peaks in the fingerprint, then the total factor scores of the concentrations at different times were calculated using PCA and were employed instead of the concentrations to compute the cumulative amounts (Q12) and enhancement ratio (ER), the latter of which were considered as the indexes for optimizing penetration enhancers. Compare to the control group, the ER of the other groups increased significantly and furthermore, 2.5% azone with 2.5% menthol manifested the best effect. PCA represent most information in the receptive solution, the method above could choose the best penetration enhancers, it could be a reference for the study of transdermal delivery of Chinese medicinal formulae.

Objective:To prepare a novel dental lithium disilicate glass-ceramic,and to study its properties.Methods:A2 colored novel glass-ceramic was prepared by sintering technique.The flexural strength,density,elastic modulus,hardness,fracture toughness, translucency and microstructure of the novel glass-ceramic and IPS e.max Press (LT A2,MO1 and HO1 )ceramic ingots were studied. Results:The novel glass-ceramic demonstrated a lower flexural strength (31 5 MPa)than MO ceramic ingot(338 MPa)(P <0.05). The other mechanical properties of the novel glass-ceramic were similar to those of LT and MO ceramic ingots(P >0.05).The translu-cency parameter of the novel glass-ceramic(21 .2)was higher than that of HO(1 6.5)but lower than that of LT(27.8)and MO(27.5) ceramic ingots(P <0.05).SEMimages showed an interlocking microstructure of rod-shaped Li2 Si2 O5 crystals in all the glass-ceramics investigated.Conclusion:The mechanical properties,translucency and microstructure of the novel glass-ceramic are similar to those of IPS e.max Press ceramic ingots,which can meet the requirements of clinical application.

Objective To investigate the incidence of electrocoagulation syndrome after endoscopic submucosal dissection (ESD) in the colorectal laterally spreading tumors (LST) and the risk factors. Methods Data of 51 patients with coloretral LST,treated with ESD from January 2010 to May 2014 at Shengjing hospital affiliated to China Medical University,were reviewed.The incidence of electrocoagulation syndrome was analyzed and logistic regression was used to evaluate risk.Results The incidence of electro-coagulation syndrome was 9.8%(5 /51).The incidence of tumors in the rectal area(7.1%,2 /28)was lower than that of the left half colon (12.5%,1 /8),and the right colon (13.3%,2 /15).Multivariable logistic regression analysis showed that the independent risk factors for the development of electrocoagulation syndrome were LST located in non-rectum area (OR =1.655,P <1.655),lesion size larger than 25 mm (OR =1.028, P <0.05),the operation time longer than 129 min (OR =1.016,P <0.05),age older than 62 year old (OR =0.987,P <0.05).Conclusion For the patients aged over 62 year old,lesion size larger than 25 mm,the operation time longer than 129 min and LST located outside the rectum,the mucous membrane should be separated from the muscularis propria in the ESD procedure to reduce electrocoagulation time as much as possible. In the postoperative period,patients need fasting,fluid replacement support,and prevention of post endoscopic submucosal dissection electrocoagulation syndrome (PEECS).
