OBJECTIVE:To study the pharmacokinetics effects of naloxone combination on Shenmai injection in rats in vivo. METHODS:12 rats were randomly divided into monotherapy group (Shenmai injection 9.00 ml/kg,iv) and combination group (Shenmai injection 9.00 ml/kg+naloxone 1.80 ml/kg,iv). The blood samples were collected before administration and 0.083,0.25, 0.5,0.75,1,1.5,2,3,6,12,24,48,96 and 144 h after administration. HPLC was adopted to determine the plasma concentra-tions of ginsenosides Rg1,Re and Rb1,and DAS 2.0 software was used to calculate the pharmacokinetic parameters. RESULTS:Compared with monotherapy group,the plasma concentration of ginsenosides Rg1 in combination group was increased,CL was de-creased,t1/2 and MRT were prolonged,and AUC0-144 h was increased;the plasma concentration of ginsenosides Re was increased,Ke was decreased,t1/2 was prolonged,MRT was shortened,and AUC0-144 h was increased;the plasma concentration of ginsenosides Rb1 was decreased,Ke was increased,t1/2 and MRT were shortened,and AUC0-144 h was decreased,with significant differences(P<0.01 or P<0.05). CONCLUSIONS:Shenmai injection combined with naloxone can slow down the removing of ginsenosides Rg1 and Re in vivo,and obviously the plasma concentration of Shenmai injection is higher than monotherapy group;speed up the removing of ginsenosides Rb1,and the plasma concentration of Shenmai injection is lower than monotherapy group obviously.

PurposeTo analyze the far infrared thermography characteristics before and after surgery in patients with acoustic neuroma.Materials and Methods Thirty-two patients with acoustic neuroma were included as observation group and 40 normal healthy individuals as control group. Un-cooled thermal imaging system (ATIR-M301B) was used with working temperature of 20-25℃. Craniofacial infrared images were collected to analyze temperature differences among different detection zones.Results Far infrared thermography revealed that there were no obvious temperature differences between both sides of supraorbital region, endocanthion region, frontal region and buccal region in the control group (P>0.05). The temperature differences in bilaterally symmetrical parts of supraorbital region, endocanthion region, frontal region, buccal region were significantly higher in observation group (t=1.557, 1.714, 1.483 and 1.569,P<0.05). The craniofacial temperatures of 32 patients changed after operation, and the differences reduced in supraorbital region, endocanthion region, frontal region, and buccal region (t=2.655, 2.462, 2.897 and 4.465,P<0.05).Conclusion Far-infrared thermography inspection can detect abnormal temperature changes.

The changes of the growth characteristics and surface ultrastructure during longterm passages of Wg3h cells that have been transfected with PSV_2-neo (Wg3h-neo) were studied. The results showed that the growth and DNA synthesis rate were evidently higher in the transfected cells than in the parental wg3h cells. The saturation of the transfected cell growth density was also increased, but neither the parental and transfected cells formed cell colony in soft agar medium nor tumor growth in nude mice. There was no significant differences in morphology between the two cell types under light microscopy, however much more microvilli were seen on the transfected cell surface under scanning electron microscopy. Southern blot hybridization analysis indicated that the PSV_2-neo plasmids were integrated into the genome of the target cells. Our results demonstrated that the transfected cells remained as nonmalignant cells although some changes of their growth characteristics and surface ultrastructure appeared.

Objective To explore the occurrence site, clinical manifestations, endoscopic and radiographicfeatures, pathologiccharacteristics, diagnosis, treatmentandprognosisof gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN).MethodsFrom January 2000 to June 2010,medical records of 87 GEP-NEN patients in the First Affiliated Hospital of Sun Yat-sen University were collected. The neuroendocrine properties of the tumors were determined by immunohistochemistry staining of neuroendocrine markers Syn and CgA.Then according to histology and proliferation activity, the GEP-NEN tumors were classified as neuroendocrine tumor (G1 and G2 grade), neuroendocrine carcinoma (G3 grade) and mixed adenoendocrine carcinoma (G3 grade).Results36 cases (41.4％) of GEP-NEN tumors were in pancreas, followed by 18 cases in rectum (20.7％), 9 cases in stomach (10.3％) and 6 cases in duodenum (6.9％).Total 69 of 87 GEP-NEN cases (74.7％) were nonfunctional tumors, a variety of gastrointestinal symptoms or symptoms caused by local tumor compression were the most first symptoms, and no one case presented carcinoid syndrome.The manifestations of endoscopy and radiographic image were tumor occupying lesion.Of 87 GEP-NEN cases, 69 cases were neuroendocrine tumor (79.7％), 13 cases were neuroendocrine carcinoma (14.9％) and 5 cases were mixed adenoendocrine carcinoma (5.4％).The percentage of grade G1, G2 and G3 tumors were 64.9％、 14.9％ and 20.2％ respectively.Muscularis or serosa infiltration were found in 22 GEP-NEN patients (47.8％) at the first visit, lymphatic metastasis was in 18 cases (20.7％) and distant metastasis were in 18 cases (20.7％), mostly migrated to liver.Immunohistochemistry staining positive rates of CgA and Syn were 74.2％ and 88.1％.A total of 79 patients (90.8％) were underwent surgery.The 1-, 3-and 5-year survival rates were 76.9％, 54.2％and 41.7％ during follow-up.ConclusionsGEP-NEN may occur at any part of the digestive system,the clinical manifestations are variable.Endoscopy and radiographic examination play an important role in tumor diagnosis, but final diagnosis is mainly based on pathological detection, and surgery is the main treatment option.The prognosis of the tumor is correlated with the pathological classification,grading and condition of distant metastasis.

Objective To explore the value of serum chromogranin A (CgA) in clinical diagnosis and efficacy evaluation of gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN).Methods From January 2011 to December 2012,87 GEP-NEN patients were enrolled,which included 50 patients with lesions and 37 patients without lesions after surgery.Eighty-four healthy subjects were taken as control group.The serum CgA levels of all subjects were measured with enzyme linked immunosorbent assay.Nonparametric test,receiver operating characteristic curve and Cox regression univariate analysis were performed for analysis.Results The median of serum CgA level of GEP-NEN patients with lesions was 97μg/L,which was significantly higher than that of patients without lesions after surgery (42 μg/L,Z=3.451,P=0.001) and healthy control (47 μg/L,Z=3.149,P=0.002).The value of 95 μg/L was taken as diagnostic cut-off value for healthy controls,patients without lesions and patients with lesions,the sensitivity and specificity were 54.0％ and 90.1％,respectively.The median of serum CgA level of the patients with distant metastasis was 231 μg/L,which was higher than that of patients without distant metastasis (46 μg/L,Z=3.340,P=0.001).After treatment,the serum CgA levels of 12 patients with complete remission,partial remission or stable tumor decreased more than 20％ of baseline values.The serum CgA levels of five patients increased more than 20 ％ of baseline values and the tumors of them showed progress.Cox regression analysis showed that there was no correlation between CgA levels of patients with lesions and prognosis (r=1.000,P=0.252).Conclusion Neuroendocrine marker CgA has high diagnostic value in GEP-NEN,and can be used as an important biomarker in clinical diagnosis and efficacy evaluation of GEP-NEN.

Objective To explore the expression,correlation and clinical significance of mammalian target of rapamycin (mTOR) and vascular endothelial growth factor (VEGF) in gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN).Methods From October 1995 to December 2012,the paraffin tissue specimens of 114 pathological diagnosed GEP-NEN were collected.The expressions of mTOR and VEGF at protein level were detected with EnVision immunohistochemical staining method.Chi-square test was performed to compare the differences in the expressions of mTOR and VEGF among every clinicopathological factors of patients.Spearman's correlation analysis was used to find out the correlation between the expressions of mTOR and VEGF.Kaplan Meier method and Log-rank test were implemented for survival analysis.Results The overall positive expression rates of mTOR and VEGF in GEP-NEN tissues were 66.7％ (76/114) and 71.1％ (81/114),respectively.The expressions ofmTORand VEGF at protein level were not correlated with gender,age,functional status of tumor,location of tumor,grading and classification of tumor and distant metastasis (all P＞0.05).The co-expression rate of mTOR and VEGF in GEP-NEN tissues was 51.8％ (59/114).The expression of mTOR was positively correlated with the expression of VEGF at protein level (r=0.205,P=0.029).Among 82 followed-up patients,the mean survival time of patients with mTOR positive or negative expression was 8.3 and 7.9 years,and respectively,and there was no statistical significance (x2 =0.201,P=0.654).The mean survival time of patients with VEGF positive or negative expression was 9.6 and 5.9 years,respectively,and the difference was statistically significant (x2 =4.415,P=0.036).Among the patients with G1 grading tumor,classified as neuroendocrine tumor and without distant metastasis,the survival time of patients with positive VEGF expression was longer than that of patients with negative VEGF expression (11.8 years vs 7.3 years,x2 =5.349,P=0.021; 11.2 years vs 6.8 years,x2=6.375,P=0.012; 11.2 years vs 7.2 years,x2 =4.630,P=0.031).Conclusions mTOR and VEGF proteins are highly expressed in GEP-NEN with different location,grading and classification.The expression of them is positively correlated.The prognosis of GEP-NEN patients with positive VEGF expression is better.
