Objective To analyze the development, treatment, death cause and survival situation of malignant tumor in aging patients Method Retrospectively analysis was made on 106 aging patients died of malignant tumors, who received the treatment in our hospital. Result Of all 106 patients, 102 patients were in advanced stage(Ⅲ+Ⅳstage), occupying 96.23%,most of who also had some other basic senile diseases; 96.23% patients had been treated with TCM, which exceeded the ones who were treated with chemotherapy, radiotherapy and operation. Some aging patients with tumor had better survival time than other age patients; the top three causes of death for tumor were respiratory failure, infection and congestive heart failure. Conclusion Most of aging patients with malignant tumor were in advanced stage, TCM treatment is easily to be accepted by patients, due to its fewer side effects. In the meantime, we should treat the basic senile diseases positively and prevent their complications.

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 extract alkaloids from Corydalis decumbens (AsCD) by supercritical CO2 fluid extraction (SFE) and to evaluate protective effects of AsCD against hydrogen peroxide (H2O2)-induced apoptosis in rat PC12 cells.Methods AsCD were extracted by SFE and oxidative damage PC12 cells model was induced by H2O2.The survival rate of the cells was determined by MTT assay; Lactate dehydrogenase release was determined by ultraviolet spectrophotometry; Flow cytometry was used to detect apoptosis; Caspase-3 mRNA and protein were determined by real-time PCR and Western blotting assay,respectively.Results AsCD remarkably reduced the cytotoxicity,prevented membrane damage,and inhibited cell apoptosis.AsCD inhibited Caspase-3 mRNA and protein expression induced by H2O2 in PC12 cells.Conclusion AsCD possess protective effects against H2O2-induced apoptosis in PC12 cells,and the mechanism of AsCD responsible to the inhibition of apoptosis is possibly attributed to thedown-regulating Caspase-3 expression.AsCD might be useful in the treatment of oxidative stress-related neurodegenerative diseases.

Objective To investigate the effect of percutaneous vertebroplasty and kyphoplasty (PKP) on bone density and serum leptin in patients with osteoporotic thoracolumbar compression fractures. Methods One hundred and two patients with osteoporotic thoracolumbar vertebral compression fractures and 100 cases of healthy control were treated with PKP surgery. The serum leptin and adiponectin, and the bone mineral density of the lumbar spine were determined. Results patients Levels of the serum leptin and adiponectin in patients with osteoporotic thoracolumbar vertebral compression fracture were significantly higher than those with non osteoporotic fracture patients (P < 0.05). One month post-PVP, the levels of serum leptin and adiponectin in the two groups were significantly decreased (P < 0.05). postoperative group of The lumbar bone density at 1 month post-operation was is significantly higher than that before operation in each group (P < 0.05, respectively), with no significant difference between the two groups. The levels of serum leptin and adiponectin were negatively correlated with the bone mineral density (BMD) (P < 0.05). Conclusions tLevels of serum adiponectin and leptin were both increased in osteoporotic or non bone osteoporosis thoracolumbar vertebral compressor fractures. The percutaneous vertebroplasty forming operation could effectively reduce the serum level of leptin and adiponectin, and improve the bone mineral density of the lumbar vertebrae.

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.
