Objective To establish a method for the simultaneous determination of adenosine, chlorogenic acid, caffeic acid, baicalin and wogonin in Ganmaoning granules. Methods The UPLC-MS/MS method was adopted. The separation was performed on ZOBAX SB C18 (2.1 mm×150 mm, 5μm) column with mobile phase consisted of methanol-2 mmol/L ammonium acetate aqueous solution (isocratic elution) at the flow rate of 0.2 ml/min. The column temperature was set at 35℃, and the injection volume was 2μl. The electrospray ionization source (ESI) was used. Multiple reaction monitoring (MRM) mode was adopted, using positive and negative ions scanning. The ion source temperature was 300℃, the drying gas temperature was 400℃, the drying gas flow was 20 L/min, the atomizing gas pressure was 55 psi, and the capillary voltage was 4000 V.Results The linear ranges of adenosine, chlorogenic acid, caffeic acid, baicalin and wogonin in Ganmaoling granules were 0.20-12.80 ng (r=0.9996), 1.00-64.00 ng (r=0.9998), 0.40-25.60 ng (r=0.9996), 4.00-256.00 ng (r=0.9992), 0.20-12.8 ng (r=0.9991), which showed the linear relationship was good. The limits of detection were 0.02, 0.10, 0.04, 0.40, 0.02 ng, respectively. The limits of quantitation were 0.04, 0.20, 0.08, 0.80, 0.04 ng, separately. TheRSDs of precision, reproducibility and stability (24 h) tests were no more than 3.5％. The recovery rates were 99.3％-100.75％ (RSD=2.09％-3.17％).Conclusions The method established in this experiment is simple, rapid, sensitive and accurate. It can be used to simultaneously determine the contents of five components inGanmaoling granules, and can be used for quality control ofGanmaoninggranules.

Objective To evaluate the short-term therapeutic efficacy of Cyberknife in alleviating the pain of locally advanced pancreatic cancer (LAPC) and explore the application of DWI in the pain evaluation.Methods Visual analogue scale (VAS) and Quality of life score KPS were conducted in 36 LAPC patients before and 1 month,3 month after radiotherapy,who underwent conventional MRI examination and DWI scan.The changes of VAS and KPS scores were observed before and after the treatment,as well as the apparent diffusion coefficients (ADC) changes of region of interest (ROI) in the DWI images,and the correlation of ADC with KPS and VAS was analyzed.Results VAS before and at 1 month and 3 month after the treatment was (4.89 ± 2.89),(1.08 ± 2.06) and (0.51 ± 1.48).KPS before and at 1 month and 3 month after the treatment was (72.47 ± 14.74),(93.33 ± 10.69) and (92.86 ± 10.73).ADC of DWI before and at 1 month and 3 month after the treatment was 1.47 ± 0.28,1.79 ± 0.33 and 1.94 ± 0.41,and the differences were statistically significant (all P values ＜0.001).VAS was obviously decreased at 1 month and 3 month after the treatment,while KPS and ADC were greatly increased,and the differences were statistically significant (P value ＜ 0.05).There was no statistical difference between those at 1 month and those at 3 month.There was no obvious correlation between ADC and VAS and KPS at 1 month and 3 month after the treatment.Conclusions After Cyberknife treatment,the pain was obviously relieved and the life quality was greatly improved within short period,but ADC of DWI can not sensitively monitor the changes of the pain.

OBJECTIVETo analyze the feasibility of No.8p lymphadenectomy for the patients with advanced gastric cancer and to preliminaryly explore its value in improving prognosis.

METHODSClinical data of 1158 patients with advanced gastric cancer undergoing radical gastrectomy plus D2 or above D2 lymphadenectomy (No.8 lymphadenectomy) from July 2003 to July 2013 at Department of Gastrointestinal Surgery, Fujian Cancer Hospital were collected. A retrospective cohort study was carried out. Among 1158 patients, 343 patients from July 2003 to June 2008 only received No.8a lymph node dissection (No.8a group), and 815 patients from July 2008 to July 2013 received No.8a+No.8p lymph node dissection (No.8a+No.8p group). Patients in No.8a group received the dissection of the lymph nodes in the upper margin of the pancreas and the front of total hepatic artery, and those in No.8a+No.8p group, on the basis of No.8a group, received the dissection of lymph nodes in the common hepatic artery and the left lymph nodes behind the hepatic artery and the portal vein. The metastasis degree and metastasis rate of lymph node(No.8a and No.8p), as well as intraoperative and postoperative presentations in both groups were investigated. The prognosis of two groups were analyzed with Kaplan-Meier method and Log-rank test.

RESULTSAmong 1158 patients with advanced gastric cancer, 849 were males and 309 were females with aged 17 to 83(58.5 ±11.7) years. Radical distal gastrectomy was performed in 325 cases (28.1%) and radical total gastrectomy in 833 cases(71.9%). All the patients completed operations successfully. A total of 2587 No.8a lymph nodes were removed, and the lymph node metastasis rate and metastasis degree of No.8a were 20.6% (239/1158) and 13.0%(336/2587), respectively. A total of 2170 No.8p lymph nodes were removed, and the lymph node metastasis rate and metastasis degree of No.8p were 10.9%(89/815) and 7.2%(156/2170), respectively. The operation time of the No.8a+No.8p group was longer than that of No.8a group [(180.2±40.3) minutes vs. (168.4±41.8) minutes], and the difference was statistically significant (t=-4.627, P=0.000). However, intraoperative blood loss [(222.8±92.8) ml vs. (215.6±91.1) ml], postoperative 1-day peritoneal drainage volume [(257.7±120.0) ml vs. (270.3±121.0) ml], time to withdraw of gastric tube [(2.1±0.9) days vs. (2.2±0.8) days], time to withdraw of peritoneal tube [(6.8±1.1) days vs. (6.9±1.1) days], time to withdraw of nasal feeding tube[(6.5±1.2) days vs. (6.4±1.1) days], the morbidity of complications [19.8%(68/343) vs. 16.0%(130/815)] and postoperative hospital stay [(8.1±3.0) days vs.(8.3±3.1) days] in No.8a group and No.8a+No.8p group were not significantly different(all P>0.05). The average follow-up period was 41(2 to 144) months. The median postoperative survival was 83.0 months, and the 1-, 2-, and 5-year survival rates were 90.9%, 78.8% and 56.9% in No.8a group respectively. The median survival was 94.8 months, 1-, 2-, and 5-survival rates were 94.9%, 82.3% and 63.0% in No.8a+No.8p group respectively. The survival rate of No.8a+No.8p group was significantly higher than that of No.8a group (P=0.016). The stratified analysis showed that in stage II patients, the survival rate of No.8a+No.8p lymph node dissection was significantly higher than that of only No.8a lymph node dissection(P=0.021), but difference of survival between two groups was not significantly different in stage I patients(P=0.469) and stage III patients (P=0.820).

CONCLUSIONFor the patients with advanced gastric cancer, the dissection of No.8a+No.8p is safe and feasible, and may improve the prognosis, especially for those with stage II, suggesting that No.8a+No.8p lymphadenectomy should be performed for selected patients with advanced gastric cancer.

Objective To explore the value of Multiple b value DWI ( MbDWI ) in the short-term efficacy evaluation of cyberknife radiotherapy for locally advanced pancreatic cancer ( LAPC ) .Methods A total of 36 patients underwent both conventional sequence and respiratory triggered MbDWI ( b=0, 25, 50, 75, 100, 150, 200, 400, 600, 800, 1 000 s/mm2 ) before cyberknife radiotherapy, 1month and 3 months after the radiotherapy, respectively.ADCtot, f, Dfast and Dslow were calculated using single and double exponential model and the changes before and after radiotherapy were observed.Results Before radiotherapy, 1 month and 3 months after radiotherapy, the ADCtot values of solid lesions were (1.56 ±0.29) ×10-3 mm2/s, (1.75 ±0.31) ×10 -3 mm2/s and (18.6 ± 0.46) ×10 -3 mm2/s;the values of Dslow were (1.10 ±0.73) × 10 -3 mm2/s, ( 1.19 ±0.97 ) ×10 -3 mm2/s and ( 1.49 ±04.6 ) ×10 -3 mm2 s/; the values of Dfast were (83 .33 ±62 .57) ×10 -3 mm2/s,(124.57 ±123.10) ×10 -3 mm2/s and (108.07 ±96 .67) ×10 -3 mm2 /s; f values were (26.81 ±23.74)%,(23.61 ±22.75)% and (21.34 ±15.36)%, respectively.ADCtot values 1 month and 3 months after treatment were significantly higher than those before treatment and Dslow 3 months post-treatment was higher than that before treatment, and the differences were statistically significant ( both P<0.05) and no other differences between two groups were significant.There were no statistical differences on Dfast and f before and after radiotherapy.Conc lusions ADCtot and Dslow both showed a significant growth trend after cyberknife radiotherapy.The advanced degree of parenchymal cystic in the targeted lesion could reflect the short-term efficacy of cyberknife treatment.

Objective: To explore the relationship between the ratio of neutrophil/lymphocyte (NLR) and in-hospital major adverse cardiac events (MACE) in patients with acute ST-elevation myocardial infarction (STEMI) at early admission.
Methods: A total of 420 acute STEMI patients admitted and received primary PCI in our hospital from 2010-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups:In-hospital MACE group, n=47 and Normal discharged group, n=373. Uni-and multivariate analyses were conducted to assess whether high NLR is the independent predictor for in-hospital MACE occurrence.
Results: Univariate regression analysis indicated that the occurrence rate of in-hospital MACE in high NLR patients were higher than those in low NLR patients (OR=3.19, 95%CI 1.55-2.65, P=0.012). Multivariate regression analysis showed that high NLR was the independent risk factor for in-hospital MACE occurrence in STEMI patients (OR=3.05, 95%CI 1.59-10.54, P=0.015).
Conclusion: High NLR is the independent risk factor for in-hospital MACE occurrence in STEMI patients at the early admission.
