Objective:To establish a patient-derived xenotransplantation (PDX) animal model of gastric cancer, and observe the anti-cancer effect of chemotherapeutic drugs on this model.Methods:Human gastric cancer tissues were inoculated into the subcutaneous tissues of both axillaries of NOG mice and were subcultured for 3 generations. The tumor tissues of the third-generation NOG mice were selected and inoculated into the subcutaneous tissues of left axillary of 21 severe combined immunodeficiency-non-obese diabetes mellitus (SCID-NOD) mice to establish PDX mouse model of gastric cancer. The inoculated mice were divided into control group (mice received only 0.9% sodium chloride injection), oxaliplatin group, cisplatin group, paclitaxel group, fluorouracil group, tegafur, gimeracil and oteracil porassium capsules group and capecitabine group, with 3 mice in each group, and the corresponding drugs were given. The mice survival status, tumor volume and tumor weight at different times were recorded. Mice were sacrificed on the 61st day of administration, and the tumor inhibition effects of 6 kinds of chemotherapy drugs on the PDX model of gastric cancer were evaluated.Results:After being subcultured for 3 generations, the stability of tumor transmission in PDX animal model of gastric cancer was improved, and the homogeneity of tumor growth was good at the initial stage. At the early stage of administration, the model was more sensitive to oxaliplatin, fluorouracil and capecitabine, and the tumor growth inhibition (TGI) values on the 31st day were 63.37%, 52.11% and 78.48%, at the end of administration, the model had the best sensitivity to capecitabine with a TGI value of 59.22% and a tumor inhibition rate of 58.65% on the 61st day. The TGI curve after administration showed that paclitaxel had no obvious anti-tumor effect, cisplatin had the worst anti-tumor effect, and the model had poor tolerance to tegafur, gimeracil and oteracil porassium capsules.Conclusion:The PDX animal model of gastric cancer is successfully established, and capecitabine has the best tumor suppressive effect on this model.

Objective To fractionate phosphoproteome of mouse liver by two-dimensional (2D) liquid phase chromatography fractionation. Methods Phosphoproteins were extracted from lysates of normal mice livers by phosphate metal affinity chromatography (PMAC) resin. The phosphoproteins were exchanged by start buffer and separated by chromatofocusing in the first dimension. Then the fractions between pH 8.5 and pH 4.0 were separated by non-porous silica (NPS) reverse-phase high performance liquid chromatography (RP-HPLC). Finally, the UV maps were converted into gel-like maps by ProteoVue software. Results Phosphoproteins of mouse liver were successfully extracted and fractionated by two dimensional liquid phase chromatographic fractionation after concentration and desalt. Then pI/UV map of mouse liver phosphoproteome was successfully set-up. There are 16 fractions between pH 8.5 and pH 4.0 after chromatofocusing in the first dimension and the UV maps of each fraction were converted into pI/UV gel-like maps. Conclusions Combination of technique of phosphoproteins enrichment and 2-D liquid phase chromatographic fractionation is an effective approach to research phosphoproteome and the key base for further identification and investigation of phosphoproteins.

Objective Exploration of TSH, FT3, FT4 changes in critical condition prior to death.Methods 84 patients that were anti-tumor therapy acceptable and not associated with the treatment of thyroid disease in patients with terminal tumors. Age from 24 to 85-year-old, male 56, female 28. The use of SELDI technology (surface-enhanced laser description / ionization time-of-flight mass spectrometry protein chip technology) checks to M/Z for the 11 100 + H～11 900 + H peak of the cluster, divided into the positive group for critically ill patients with early warning protein (LGT) and the negative group for it. All patients were given TSH, FT3, FT4 inspection. The results were statistically analyzed. Results TSH, FT3, FT4 in the LGT positive group was significantly lower than in the negative LGT group. There was no correlation between TSH,FT3 and FT4 in the LGT positive group;In the negative LGT group FT3 and FT4 had a positive correlation,and FT3 and TSH no relevance. Conclusion Thyroid function is normal in the stage of cancer patients stable condition. Possible pituitary-hypothyroidism may occur as the disease advances to the end or before death.This may be an important factor causing the acceleration to the death of the patients. However, the cause and effect between this phenomenon and the early warning of protein fingerprint group(LGT) is still not clear. In critical condition checking thyroid function and render supplementary amount of thyroid hormone in accordance with the checking results may be beneficial.

Objective To observe the effects of hydrocortisone on the rate of return of spontaneous circulation(ROSC)and the outcome of patients with cardiac arrest(CA)and cardiopulmonary resuscitation(CPR). Methods A cohort study was conducted,78 non-traumatic patients with CA were divided into hydrocortisone group (31 cases)and control group(47 cases). Conventional treatments were given in the two groups after admission,and additionally intravenous 100 mg hydrocortisone was given to the hydrocortisone group during resuscitation. The ROSC rate and prognosis were compared between the two groups. Multivariate logistic regression analysis was used to predict the impact factor of ROSC. Results The ROSC rate and 24-hour survival rate in the hydrocortisone group were significantly higher than those of the control group(ROSC rate:58.1% vs. 40.4%,24-hour survival rate:48.4%vs. 36.2%,both P<0.05). There were no significant differences between the hydrocortisone and the control groups in duration of CPR〔minute:17.1(6-45)vs. 15.8(7-48)〕,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score in survivors(37.2±8.2 vs. 36.1±8.2),the survival rate(12.9% vs. 12.8%)and hospital discharge rate(6.4%vs. 6.4%)in 7 days. Hydrocortisone〔odds ratio(OR)=3.12,95%confidence interval(95%CI)-1.18-8.29, P=0.017〕and witness(OR=4.24, 95%CI -1.87-12.43,P=0.008) were independent predictors for an increased ROSC rate after multiple logistic regression analysis. Conclusion Giving hydrocortisone during resuscitation may increase ROSC rate in CA patients.
