OBJECTIVE:To study the impact of ethanol volume fraction on the extract rate of ginsenoside monomer. METH-ODS:Water and different volume fraction of ethanol solution(20%,50%,70%,95%,V/V)were used for ginseng extract. High performance liquid chromatography-quadrupole-time of flight-mass spectrometry (Q-TOF LC/MS) was applied to identify compo-nents attributable of each peak. Especially 16 kinds of main saponins were analyzed. RESULTS:The volume fraction of ethanol had a significant impact on extract rate of ginsenoside. When the volume fraction of ethanol was 70%,extract rate of ginsenoside was the highest;however,the differences were mainly caused by protopanaxatriol saponins. The yield of protopanaxadiol ginsen-osides was similar in different volume fraction of ethanol solution. CONCLUSIONS:When the volume fraction of ethanol is differ-ent,result is not only different in the total saponin,but also different in the proportion of the monomers.

Objective To explore the clinical value of gastric bare area (GBA) for the prognosis of gastric fundus and cardia carcinoma.Methods The data of 82 patients with gastric fundus and cardia carcinoma from January 2010 to December 2011 were retrospectively analyzed.The patients were divided into group A (49 cases) with cancer cell invasion in GBA and group B (33 cases) without invasion in GBA.All the patients underwent D2 gastrectomy plus surgical resection of GBA and were treated by 6 cycles of postoperative FOLFOX-4 chemotherapy scheme.Postoperative follow-up and survival analysis were carried out for patients in both groups.Results According to survival analysis (Kaplan-Meier method),the postoperative 1-,2-and 3-year cumulative survival rates of the patients in group A were 91.8 ％,57.3 ％ and 29.0 ％,respectively,while those of the patients in group B were 93.9 ％,75.0 ％ and 48.2 ％,respectively.The median survival times of the patients in group A and group B were 27.0 months and 36.0 months,respectively,which was demonstrated existing statistical significance(X2 =4.972,P =0.026).Conclusions The prognosis of gastric fundus and cardia carcinoma patients with invasion in GBA by cancer cells is poor.Surgical resection of GBA may help to improve the prognosis of the patients with gastric fundus and cardia carcinoma.

Objective:To study the effect of IL-17 on viral myocarditis in mice. Methods:We randomly selected 20 wild type BALB/c mice as the control group,20 IL-17A-/- mice for IL-17A-/- group,20 IL-17A-/- mice for IL-17 group. Each mouse had intrap-eritoneal injection of Coxsackie virus B3 (Coxsackie virus B3,CVB3) to construct VMC model. The serum levels of IL-17 were detected by ELISA method,and Th17 cells were detected by flow cytometry. After 3 days of treatment with CVB3,100 μg IgG antibody was injected intraperitoneally in control group and L-17A-/- group,and 100 μg IL-17mAb was injected with IL-17 group. Mice myocardium was collected at 3rd,7th and 14th days,respectively,after CVB3 treatment. Pathological examination was carried out on the myocardial sections of mice and stained with H&E. Virus titer in mouse myocardium was examined. The contents of TNF-α,IL-6,IL-23 and IL-17 in myocardial tissue were detected by enzyme linked immunosorbent assay. Results:We successfully constructed the model of mice with viral myocarditis. The levels of Th17 and IL-17 in serum of IL-17 group were significantly lower than those in control group and IL-17-/-group. On the fourteenth day after CVB3 treatment,the degree of myocardial tissue damage in the control group was significantly higher than that in the IL-17A-/- group and the IL-17 group(P<0. 05),the degree of myocardial injury in IL-17 mice was higher than that in the IL-17A-/- group. The virus titer of the control group was higher than that of IL-17A-/-group and IL-17 group,and the control group was increased with the increase of CVB3 treatment phase (P< 0. 05). After the IL-17mAb was injected,the virus titer of IL-17 group was higher than that of IL-17A-/- group. The levels of IL-17, IL-23, IL-6 and TNF-α in IL-17-/- group and IL-17 group were significantly lower than those in control group. The levels of IL-17,IL-23,IL-6 and TNF-αin IL-17 group were significantly higher than those in IL-17-/-group (P<0. 05). Conclusion:IL-17 is an important inflammatory factor in viral myocarditis,and IL-17 deletion can protect myocardium from viral myocarditis in mice.

Objective To explore the clinical value of combined detection of serum carbohydrate antigen 724 (CA724),carcinoembryonic antigen (CEA),and tumor necrosis factor-α (TNF-α) for the diagnosis,assessment of curative effect,and illness monitoring for advanced gastric cancer (AGC).Methods Serum levels of CA724,CEA and TNF-α were measured by the methods of chemiluminescence and compared in 20 patients with AGC (Group A),20 patients with benign gastric disease (Group B),and 20 healthy adults (Group C).Also,serum levels of CA724,CEA and TNF-α in peripheral blood as well as in portal vein were measured and compared before and after surgical treatment in patients of group A.Results The serum levels of CA724,CEA and TNF-α in patients of group A were significantly higher than groups B and C (P ＜ 0.05).In addition,the serum levels of CA724,CEA and TNF-α in patients of group A were decreased after surgical treatment and increased slightly after one month (P ＜ 0.05).Conclusions The serum levels of CA724,CEA and TNF-α in most patients of AGC are significantly elevated and the combined detection of serum CA724,CEA and TNF-α contributes to the diagnosis,assessment of curative effect,and illness monitoring for AGC.

In June 2016,a disease among the cultured rock carp (Procypris rabaudi) in Yongchuan of Chongqing Municipality occurred.The aim of this study was to investigate biological characteristics and provide reference for Aeromonas veronii identification diagnosis and treatment.Pathogenic bacteria strain YY01 from the dying fishes were examined and isolated.Strain YY01's taxonomic status was identified by observing the morphology,studying the physiological and biochemical characters and sequencing the 16S rRNA and housekeeping gene gyrB.Its pathogenicity was checked by artificial infection experiment and virulence genes.Furthermore,effective medicine was detected by drug sensitivity.The 16S rRNA and gyrB gene sequence of the strain YY01 was more than 99％ homology with that of Aeromonas veronii,suggesting that the pathogen was Aeromonas veronii,which was also identified by the results of biochemical analysis.The LD50 of strain YY01 to rcok carp was 5.06 × 104 CFU/g.Four virulence genes were detected from YY01,including aerolysin (aer),hemolysin (Hly),Outer Membrane Protein Gene A (OmpA) and adhesion (Aha) genes.Antibiotic sensitivity assays showed that among 40 antibiotics tested,22 were sensitive and 11 were resistant.In conclusion,the strain YY01 is identified as Aeromonas veronii and it is proved to have strong pathogenicity.
