Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and lethal human cancers. Cur-rent studies on the relationship between complicated type 2 diabetes mellitus (T2DM) and PDAC prognosis have demonstrated inconsis-tent results. The present study aimed to determine the relationship between complicated T2DM and the clinicopathological characteris-tics of PDAC, and evaluate whether complicated T2DM is a significant predictor for overall survival in patients with resectable PDAC. Methods: In this study, clinicopathological characteristics were observed in 136 patients who underwent surgery for PDAC at the Shengjing Hospital of China Medical University between January 2009 and February 2011. The relationship between complicated T2DM and overall survival of PDAC patients was analyzed using univariate and multivariate analyses. Results:The median age of pa-tients was 60 years (range: 35-80 years). Among the 136 patients, 76(55.9%) were male. The prevalence of complicated T2DM was 27.9%in 136 PDAC cases. Preexisting T2DM was not associated with any of the clinicopathological characteristics (all P>0.05). Uni-variate analysis showed that complicated T2DM (P=0.045), maximum diameter (P=0.011), histological differentiation (P=0.013), pT stage (P=0.034), vessel invasion (P=0.032), and pTNM stage (P=0.030) were significantly associated with the overall survival of PDAC patients. The median overall survival time was 14.2 months for T2DM patients, and 18.8 months for non-T2DM patients. In mul-tivariate analysis, complicated T2DM [hazard ratio (HR), 1.873;95%confidence interval (CI), 1.187-2.954;P=0.007], poorly differenti-ated tumor (HR, 2.647;95%CI, 1.413-4.957;P=0.002), and maximum diameter≥4.0 cm (HR, 1.699;95%CI, 1.094-2.640;P=0.018) were the independent predictors associated with poor overall survival. Conclusion:Complicated T2DM was associated with poor prog-nosis. It could be used as a prognostic predictor in patients with resectable PDAC. If confirmed, these findings may provide a novel ap-proach for individualized adjuvant therapy.

Objective To explore the clinical pathological features of gastric cancer and to provide a basis for research and treatment of gastric cancer.Methods From 2001 to 2004,a total of 694 cases of gastric cancer with radical gastrectomy were collected.Gender,age,tumor location,tumor size,World Health Organization (WHO) histological type and grade,Lauren type,blood/lymphatic vessel invasion,lymph node metastasis,depth of tumor invasion (pT) and pathological TNM staging (pTNM) were retrospectively analyzed.Results Among 694 gastric cancer cases,male to female ratio was 3.96∶ 1; a total of 644 cases (92.8％) were aged from 41 to 70,and cases aged from 51 to 70 had a high incidence of gastric cancer.The predilection site for gastric cancer was cardia (33.43％),antrum (28.96％) and the body (21.76％) accordingly.The common WHO histological types were tubular adenocarcinoma (70.32 ％) and signet ring cell carcinoma (24.50 ％).The common histological grades were Ⅱ,Ⅲ and Ⅰ.The intestinal type was most common in Lauren classification,accounting for 58.93 ％; followed by the diffuse type,accounting for 22.33 ％.Blood/lymphatic vessel invasion was detected in 438 cases (63.11％),lymphnode metastasis in 504 cases (72.62％).A total of 319 cases (45.97％) were pT3 stage,241 cases (34.73％) were on pTNM Ⅲ stage.Conclusions In recent years,cardia and antrum are the predilection sites of gastric cancer.Tubular adenocarcinoma and signet ring cell carcinoma are common which indicate that the mechanism of gastric cancer pathogenesis is varied.

Objective To explore the effects of flunarizine hydrochloride on plasma calcitonin gene-related pep-tide and substance P levels after CSD in a rat migraine model of cortical spreading depression (CSD). Methods Thirty adult rats were randomly and evenly divided into three groups:control Group, CSD group and flunarizine group. The CSD waves were evoked by application of potassium chloride on brain surface with filter paper. Funarizine hydrochloride was intravenously administered to rats five minutes prior to application of potassium chloride. The plasma levels of CGRP and SP were measured by using radioimmunity assay. Statistical analyses were performed using two-sample t test and analy-sis of variance. Results CSD waves were absent in control group whereas CSD waves were induced in CSD and flunari-zine groups. The latency of the first CSD wave was longer in flunarizine group (167.90 ± 25.18 s) than in CSD group (130.90 ± 13.30 s) (P<0.01). The number of CSD waves was smaller in flunarizine group (4.50 ± 1.84) than in CSD group (8.50 ± 2.07) (P<0.01). The amplitude of CSD waves was lower in flunarizine group (11.40 ± 4.12 mv) than in CSD group (24.40±3.57 mv) (P<0.01). The levels of CGRP and SP in both CSD group (CGRP, 32.95±11.61 pg/mL;SP, 27.80±7.51 pg/mL) and flunarizine group (CGRP, 25.13 ± 5.67 pg/mL; SP, 19.45 ± 6.10 pg/mL) were higher than in control group (CGRP, 14.44 ± 6.39 pg/mL; SP, 12.36 ± 4.22 pg/mL) (P<0.01). The levels of CGRP and SP in flunarizine group (CGRP, 25.13±5.67 pg/mL;SP, 19.45±6.10 pg/mL) were lower than those in CSD group (CGRP, 32.95±11.61 pg/mL;SP, 27.80± 7.51 pg/mL) (P<0.05). Conclusions Flunarizine hydrochloride can inhibit CSD and reduce the plama levels of CGRP and SP in the rat model of CSD.

Objective To observe the dynamic distribution of the extravasated Evans Blue (EB) dye points (neurogenic inflammatory response) at the skin after acute gastric mucosal injury (AGMI) and its relation to the related regular acupoints in the locations in rats. Methods A total of 70 Wistar rats were randomized into normal control (n=10),normal saline (n=10),and AGMI (n=50) groups. The AGMI group was further divided into 5 h,2 d,3 d,4 d and 5 d subgroups with 10 rats in each. AGMI model was duplicated by intragastric perfusion of diluted hydrochloric acid (HCl,0.5 mol/L). Evans Blue Dye (50 mg/kg,50 mg/mL in 0.9% saline) was given to the rats before AGMI modeling. The plasma extravasated EB points at the skin of the whole body were observed after removal of the hair. Results The extravasated EB points presented a nerve-segmental distribution,with the proportion of the points in the location being 47.5% for "Geshu" (BL 17),58.82% for "Jizhong" (GV 6),88.23% for "Pishu" (BL 20),82.35% for "Weishu" (BL 21),17.64% for "Zhongwan" (CV 12),and 5.88% for "Shangwan" (CV 13),respectively. The plasma extravasation of EB seldom appeared in normal rats and only fewer points were found in rats accepted administration of 0.9% saline. Significant differences were found between model and normal control groups,and between model and normal saline groups in the numbers of the extravasated EB points (P

With the wide application of acupuncture in the world, the research results of neurosciences have made scientific approval on some of efficacy and mechanism of acupuncture, and the concept of western medical acupuricture (WMA) is gradually developed. During the spread of Chinese acupuncture into western countries, WMA is an adaptive improvement when facing basic theories of western medicine including anatomy, physiology and pathology as well as evidence-based medicine system. WMA which is based on theory of muscle trigger point has obvious efficacy on muscular fasciae pain, which attracted wide attention. But when Chinese acupuncture spreads into western world, the theories of Chinese acupuncture such as meridian and specificity of acupoint are questioned due to the results of western clinical study. In this paper, the origin, theory development, stimulating location and method, and categories of diseases of WMA are compared with Chinese acupuncture, and the enlightenment of this difference on Chinese acupuncture research is analyzed.
