Purpose To investigate the mutation status of KRAS and PIK3CA gene in colorectal cancer (CRC) primary lesions and corresponding liver metastasis and its clinical significance.Methods The gene mutations of KRAS and PIK3CA were detected in 58 cases of primary lesions of CRC and corresponding liver metastasis tissue by real-time PCR.Results The mutation rates of KRAS were 31.03％ (18/58) and 25.86％ (15/58) in primary lesions of CRC and corresponding liver metastasis tissue,respectively,in which G12D was most commonly detected.The mutation rates of PIK3CA were 8.62％ (5/58) and 10.34％ (6/58) respectively,in which the most common mutation site was E545K.Only one case carried simultaneously both mutations of KRAS (G12D) and PIK3CA (E545K).The mutation of KRAS and PIK3CA had a good consistency between primary lesions and liver metastasis.Univariate analysis showed that the mutation of KRAS was related to the primary lesion of tumor location,the quantity of metastasis and the types of tumor (P ＜ O.05),PIK3 CA mutation was associated with the synchronous/metachronous liver metastasis and the quantity of metastasis (P ＜ 0.05).Multivariate Cox regression analysis showed that synchronous/metachronous liver metastasis and the mutation of KRAS were influencing factors for prognosis of CRC.The overall survival of patients with CRC who had simultaneous liver metastases was longer than those with heterotopic liver metastases;the overall survival of KRAS wild-type mutant patients was longer than those of mutant patients (P ＜ 0.05).Conclusion The G12D site of KRAS gene has the highest mutation frequency in CRC,KRAS/PIK3CA mutation has a good consistency of the primary lesions of CRC and corresponding liver metastasis.Primary lesions can be as the source of molecular detection.To achieve individualized treatment,we need to reassess the genetic status of metastasis based on the choice of targeted therapy for precision medicine.

Objective To explore the effect of comprehensive intervention on anxiety in patients of acute myocardial infarction (AMI) undergoing intra-aortic balloon pump (IABP). Methods 50 patients with AMI undergoing IABP with the score of Hamilton Anxiety Rating Scale (HAMA) more than 14 points, were divided into conventional intervention group (n=25) and comprehensive intervention group (n=25). The conventional intervention group received all the conventional nursing measures including cognitive behavioral intervention, and the comprehensive intervention group received propofol intravenous pumping in addition with Ramsay sedation at II-III level. The vital signs, HAMA scores, major cardiovascular events, and vascular complications were recorded before and the 1st-5th days after intervention. Results The HAMA scores, systolic blood pressure, diastolic blood pressure and mean pressure decreased in most of the time points after intervention in the comprehensive intervention group (P<0.05). And there was no complication such as low blood pressure, respiratory depression. The incidence rates of cardiac arrhythmias, puncture hematoma/bleeding and catheter displacement were lower in the comprehensive intervention group than in the conventional intervention group (P<0.05). Conclusion Comprehensive intervention can improve the symptoms of anxiety in the patients with AMI undergoing IABP, and reduce the incidence of arrhythmia, vascular complications and catheter displacement.

Objective: To explore the application of grid health education model in improving college students health literacy. Methods: The clustered stratified random sampling method was used among the pre-formative education freshmen in a Xi-an university, with 1 123 students randomly selected totally. The intervention group (578) received health literacy education based on grid health education model, while the control group (545) receuved the original health education model. The effect of gird model of health education on health literacy was compared between two groups of college students after one-semester intervention. Results: Insufficient health literacy was found among freshmen participants in Xi an(17.12%, 17.61%); health literacy on prevention and treatment of chronic diseases (15.92%, 16.70%) was significantly lower than the national average level of urban residents(22.73%). Health literacy of the two groups of college students was significantly improved(47.75%, 27.71%, χ 2=20.50, 5.47, P<0.05). The grid health education model had significant effects in improving health literacy among college students, except for health literacy on safety and emergency(P<0.05). Conclusion Health literacy of college students is insufficient compared to that of urban residents in China. Grid model of health education model is superior to conventional health education model, which is in line with the requirements of health education in colleges in the new era.

This paper is to explore changes of intestinal mucosal barrier, intestinal flora, and bacterial translocation in rats with severe acute pancreatitis (SAP). Twenty four male SD rats were randomly divided into the control group (n = 10) and the experimental group (n = 14). The model of severe acute pancreatitis of rats was induced by the method of injecting adversely 5% sodium taurocholate into the common biliary-pancreatic duct. All of the rats were killed after 24 hours and the level of the serum amylase and the plasma endotoxin was determined after that. The pathological changes of pancreas and small intestine were observed through hematoxylin-eosin staining (HE staining) and the abdominal viscera bacterial translocation rates were tested. With the method of real-time polymerase chain reaction (RT-PCR) the quantity of the intestinal flora was analyzed. In the control group, the level of Escherichia coli, Lactobacillus and Bifidobacterium were 2.08 ± 1.29, 11.04 ± 7.55 and 12.21 ± 4.95, respectively. On the contrast, the level of Escherichia coli in the cecum contents was much higher (9.72 ± 3.58, P < 0.01), while the Lactobacillus number was decreased significantly (0.67 ± 0.34, P < 0.01), and the Bifidobacterium number was also decreased (4.59 ± 3.42, P < 0.05) in the experimental group, so the ratio of Bifidobacterium/Escherichia coli was reversed. Besides, in the experimental group, the plasma endotoxin positive rates and the bacterial translocation rates were much higher (P < 0.01 or P < 0.05) and the pathology scores of pancreas and small intestines were also significantly higher (P < 0.01) than those in the control group. These results indicated that in severe acute pancreatitis rats, the intestinal mucosal barrier was severely damaged and the dysbacteriosis occurs in the intestinal canal. And these might relate to the occurrence and development of multiple organ infection.

The basic objective of microwave hyperthermia is to raise the temperature in the tumor tissue without overheating point for a long time. It's difficult to achieve uniform temperature distribution using the continuous heating without changing the antenna shape and inserting position. In this paper, the interstitial antenna worked in the frequency of 2450 MHz inserted into an infinite muscle model is studied. The Finite Difference Time Domoin (FDTD) method was used to calculate the electromagnetic field, while the finite difference method (FDM) was used to analyze the temperature distribution in tumor tissue. The simulation results show that the long-time evenly heating can be achieved by using the alternately heating process and the treatment area can be changed by adjusting input power.

Borneol and TMP in healthy persons were absorbed, distributed and excreted rapidly. Conclusion The GC FID method is sensitive, reliable and rapid, it can be used in pharmacokinetics study of borneol and TMP in vivo.

Objective:To evaluate the benefit of autologous stem cell transplantation (ASCT) as a consolidation therapy in the survival of multiple myeloma (MM) patients at different risks. Methods:A total of 67 MM patients who received ASCT as consolida-tion therapy between August 2006 and July 2011 were enrolled in the retrospective study. The cases were divided into three risk groups on the basis of the International Staging System and fluorescence in situ hybridization. Another 67 patients who accepted consolidation chemotherapy at the same period were selected as case-paired controls matched in terms of age, sex, optimal response after induction, and risk stratifications. All the patients received bortezomib-and/or thalidomide-based induction therapies. Results:No statistical differ-ences in non-complete remission (nCR)/complete remission (CR) rate were observed between the ASCT and chemotherapy groups (44.8%vs. 37.3%, P=0.380) after the induction therapy. The progression-free survival (PFS) was longer in the ASCT group than in the chemotherapy group (32.4 months vs. 15.1 months, P<0.001). The overall survival (OS) was longer in the ASCT group than in the che-motherapy group (58.8 months vs. 42.1 months, P=0.009). both the PFS (median:30.5 months vs. 11.2 months, P<0.001) and the OS (median:85.5 months vs. 34 months, P=0.015) rates were significantly prolonged in the high-risk subgroup after ASCT. In the interme-diate-risk subgroup, neither PFS nor OS showed any significance after ASCT (P>0.05). In the low-risk subgroup, only PFS was extend-ed (median: 34.8 months vs. 17.6 months, P=0.012) after ASCT, without significant improvements in the OS (P>0.05). Conclusion:The MM patients obtained cytogenetic high-risk benefits mostly from ASCT consolidation after inductions based on novel agents.
