Objective:To determine the effect of apatinib combined with Xiaoyan decoction for the treatment of non-squamous non-small cell lung cancer. Methods:Thirty-eight patients with non-squamous non-small cell lung cancer were randomly categorized into apatinib group (group A, 18 cases) and apatinib combined with Xiaoyan decoction group (group B, 20 cases). All patients did not under-go surgical treatment, radiotherapy, or chemotherapy during the study. Results:The median progression free survival (mPFS) of ad-vanced non-squamous non-small cell lung cancer patients reached up to 3 months. The mPFS, objective response rate, and disease control rate of the apatinib combined with Xiaoyan decoction group showed no significant difference and statistical significance (P>0.05). The apatinib combined with Xiaoyan decoction group was superior to the apatinib group with regard to alleviating clinical symp-toms and adverse reactions (P<0.05). Conclusion:Xiaoyan decoction combined with apatinib can improve the clinical symptoms of pa-tients and reduce the incidence of adverse reactions in the treatment of advanced non-squamous non-small cell lung cancer.

Oleic acid is a common pharmaceutical excipient that has been widely used in various dosage forms. Gas chromatography (GC) has often been used as the quantitation method for fatty acids normally requiring a derivatization step. The aim of this study was to develop a simple, robust, and derivatization-free GC method that is suitable for routine analysis of all the major components in oleic acid USP-NF (United States Pharmacopeia-National Formulary) material. A gas chromatography-flame ionization detection (GC-FID) method was developed for direct quantitative analysis of oleic acid and related fatty acids in oleic acid USP-NF material. Fifteen fatty acids were separated using a DB-FFAP (nitroterephthalic acid modified polyethylene glycol) capillary GC column (30 m × 0.32 mm i.d.) with a total run time of 20 min. The method was validated in terms of specificity, linearity, precision, accuracy, sensitivity, and robustness. The method can be routinely used for the purpose of oleic acid USP-NF material analysis.

Objective To investigate the prognostic factors of low-and undifferentiated gastric cancer with negative metastasis of lymph nodes.Methods The clinicopathological data of 270 patients with low-and undifferentiated gastric cancer and negative metastasis of lymph nodes who were admitted to the Tianjin Cancer Hospital from January 2002 to December 2007 were retrospectively analyzed.All the patients received radical gastrectomy.One hundred and sixty-one patients had the number of lymph nodes dissected under 15,53 patients had 15-20 lymph nodes dissected,33 had 21-30 lymph nodes dissected and 23 patients with the number of lymph nodes dissected more than 30.Patients were followed up via out-patient examination,phone call and mail till October 2013.The prognosis analysis was done by COX step-wise regression.The survival curve was drawn by KaplanMeier method,and the survival was analyzed using the Log-rank test.Results All the patients were followed up for a median time of 63 months (range,2-103 months).The median survival time was 63 months (range,2-103 months),and the 1-,3-,5-year overall survival rates were 93.0％,69.5％ and 58.5％,respectively.The median survival time of the 161 patients with the number of lymph nodes dissected under 15 was 58 months (range,2-103 months),and the 1-,3-,5-year survival rates were 91.4％,59.3％ and 48.8％,respectively.The median survival time of the 53 patients with the number of lymph nodes dissected between 15 and 20 was 68 months (range,4-95 months),and the 1-,3-,5-year survival rates were 94.3％,84.9％ and 71.7％,respectively.The median survival time of the 33 patients with the number of lymph nodes dissected between 21 and 30 was 68 months (range,34-94 months),and the 1-,3-,5-year survival rates were 100.0％,97.0％ and 87.9％,respectively.The median survival time of the 23 patients with the number of lymph nodes dissected more than 30 was 60 months (range,2-84 months),and the 1-,3-,5-year survival rates were 87.5％,62.5％ and 54.2％,respectively.There was significant difference in the prognosis between the 4 groups (x2 =25.077,P ＜ 0.05).There was significant difference in the prognosis between patients who had 21-30 lymph nodes resected and those had 15-20 lymph nodes resected (x2=3.924,P ＜0.05).Significant difference was also observed in the prognosis between patients who had 15-20 lymph nodes resected and those had more than 30 lymph nodes resected (x2=4.454,P ＜ 0.05),while no significant difference was observed in the prognosis between patients who had lymph nodes resected more than 30 and those had lymph nodes resected less than 15 (x2=0.450,P ＞0.05).The results of univariate analysis showed that gender,age,location and diameter of the tumor,serosal invasion,Borrmann classification,range of gastric resection and the number of lymph nodes dissected were factors influencing the prognosis of patients with low-and undifferentiated gastric cancer and with negative metastasis of lymph nodes (x2 =4.143,12.607,23.665,11.549,26.350,8.059,5.222,25.077,P ＜0.05).The results of multivariate analysis showed that the tumor diameter longer than 5 cm and serosal invasion were the independent factors influencing the prognosis of patients with low-and undifferentiated gastric cancer and with negative metastasis of lymph nodes (HR =1.842,3.084,95％ confidence interval:1.286-2.638,1.956-4.861,P ＜ 0.05).Lymph nodes dissected for 21-30 was the protective factor of prognosis (HR =1.533,95％ confidence interval:1.229-2.248,P ＜ 0.05).Conclusions Lymph nodes dissected for 21-30 during radical gastrectomy may improve the long-term survival of patients.The tumor diameter longer than 5 cm,serosal invasion and the number of lymph nodes dissected (less than 15,15-20 and more than 30) were the independent factors influencing the prognosis of patients with low-and undifferentiated gastric cancer and with negative metastasis of lymph nodes.

OBJECTIVETo explore the clinicopathological characteristics and prognosis of familial gastric cancer(FGC) and to provide clinical evidence for rational treatment program.

METHODSClinicopathological data of 91 patients with FGC and 293 patients with sporadic gastric cancer(SGC) in our department from March 2003 to October 2007 were retrospectively analyzed and compared between the two groups.

RESULTSTumors with a diameter of less than or equal to 5 cm were more common in FGC patients than SGC patients [65.9%(60/91) vs. 52.6%(154/293), P=0.025]. Proportion of FGC patients with poor differentiation was significantly higher as compared to SGC patients [68.1%(62/91) vs. 55.6%(163/293), P=0.034]. The 5-year overall survival rate in FGC patients was significantly lower than that in SGC patients(25.6% vs. 38.9%, P=0.001). Further stratified analysis revealed that the 5-year survival rates of T4 FGC and T4 SGC patients were 14.5% and 30.5% respectively, the 5-year survival rates of N3 FGC and N3 SGC patients were 10.4% and 17.3% respectively, and the differences were statistically significant(all P<0.05), while other T stage and N stage between the two groups were not significantly different(all P>0.05). Univarite analysis showed that tumor size, tumor location, pathological type, operation method, infiltration depth and lymph node metastasis were influencing factors of prognosis of FGC. Multivariate analysis showed that tumor size(HR=2.271), pathology types(HR=1.449), lymph node metastasis(HR=1.748) and the infiltration depth(HR=1.487) were independent risk factors affecting the prognosis of patients with FGC.

CONCLUSIONCompared with SGC, FGC is associated with poor differentiation and poor prognosis.

Objective To compare the clinicopathological features of Borrmann type Ⅳ gastric cancer with other gastric cancer and explore prognostic factors of the patients with Borrmann type Ⅳ cancer.Methods We retrospectively reviewed the clinical data of 671 advanced gastric cancer patients.They were divided into 2 groups:Borrmann type Ⅳ (64 cases) and other macroscopic Borrmann types of cancer (607 cases).Their clinicopathologic characteristics and overall survival data were analyzed.Results Age,sex,tumor size,tumor location,lymph node metastasis,distant metastasis,TNM classification were discrepant between Borrmann type Ⅳ and other macroscopic Borrmann types of cancer.The 5-year survival rate of Borrmann type Ⅳ cancer patients was 20.1％,while it was 40.3％ for other types of cancer (P ＜ 0.05).The 5-year survival rate for Borrmann type Ⅳ gastric cancer and the other type gastric cancer was 50.0％ and 72.0％ at stage Ⅰ,30.0％ and 57.9％ at stage Ⅱ,18.0％ and 28.4％ at stage Ⅲ,and 16.4％ and 20.0％ at stage Ⅳ (all P ＜ 0.05),respectively.Multivariate analyses revealed age,histology differentiation type,tumor size,the Borrmann type carcinoma and tumor stage to be independent prognostic factors for survival.Conclusions Borrmann type carcinoma has unique clinicopathological features compared with other types of gastric carcinoma and is an important independent prognostic factor.

Objective To evaluate negative lymph node count (NLNC) in prediction of prognosis of T3 gastric cancer after radical resection.Method 214 T3 patients of radical gastrectomy with complete clinical and follow-up data between Jan 2003 to Dec 2007 were enrolled.Survival was determined by the Kaplan-Metier method and univariate analysis was done by Log-rank test,Multivariate analysis was performed using the COX proportional hazard regression model.-2loglikelihood value and the hazard ratio (HR) value were used to compared the value of number of lymph node-negative (NLNC) staging and pN staging and lymph node metastasis rate (MLR) in gastric cancer prognosis evaluation.Results Univariate analysis showed that,pN stage (x2 =31.664),MLR stage (x2 =34.123),tumor size (x2 =5.025),type of differentiation (x2 =5.993),Borrmann classification (x2 =5.401),NLNC stage (x2 =37.256) were related to survival (P ＜ 0.05).COX multivariate analysis showed that-2loglikelihood of pN staging is 1 336.761,HR value is 1.464,-2loglikelihood value of MRL staging is 1 335.821,HR value is 1.441.-2loglikelihood value of NLNC staging is 1 326.902,HR value is 1.725.The N0 and N1 staging prognosis in different NLNC staging was significant (P =0.008,P =0.014).Conclusions Sufficient number of negative lymph node prolongs survival and reduces the risk of early recurrence in advanced gastric cancer.
