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.

Objective To evaluate Janus kinase (JAKs) and Suppressors of cytokine signaling(SOCSs) expression in myocardium after endurance training. Methods 30 male Sprague-Dawley rats undertook 10 weeks grade treadmill training program and were sacrificed at 0 and 24 h respectively after the last exercise. JAK1,JAK2,JAK3 and SOCS1 ,SOCS2,SOCS6 expression in the myocardium were determined by im munohistochemistry method. Results The percentage of JAK1 positive cell significantly increased immediately after last running and recovered to the sedentary level 24 hrs after exercise;The percentage of JAK2 positive cell significantly increased immediately after last running and continuously at a higher level 24 hrs after exercise (P<0.01;P<0.05); JAK.3 showed no significant change either immediately or 24 hrs after exercise (P>0.05). The percentage of SOCS1 and SOCS2 positive cell also significantly increased both immediately and 24 hrs after exercise (P<0.01 ;P<0.05). However, the percentage of SOCS6 positive cell showed no significant change either immediately or 24 hrs after exercise(P>0.05). Conclusion Endurance training could induce different responses of JAK1,JAK2 and JAK3. The increased expressions of JAK1 and JAK2 might indicate the changes of JAK/STAT signal pathway in regulating myocardial function. The increased expressions of SOCS1 and SOCS2 after endurance training might indicate the increased exertion in regulating JAK/STAT signal pathway in cardiac muscle.

Objective By analyzing the cesarean delivery rate (CDR) and the indications of cesarean section in Jiangsu Province from 2012 to 2014, to find the strategy to reduce CDR.Methods Data of 40 hospitals whose number of delivery was over 2 400 per year from the database of the Quality Control Center of Gynecology and Obstetrics of Jiangsu Province from 2012 to 2014 were selected.The cohort was divided into two groups, one was specialized hospital including 11 maternal and child health hospitals and the other included 29 general hospitals.After analyzing the current status of cesarean section of the whole province, the average CDR and the distribution of the first indications of cesarean section in two groups were compared using Chi-square test.Results The average CDRs at year 2012, 2013 and 2014 were 53.8％(96 347/178 970), 51.8％ (97 509/188 142) and 48.8％(106 323/217 877), which had a trend of decrease (x2=1 026.2, P ＜ 0.01).CDR without medical indications for each year were 15.7％ (28 098/178 970), 15.5％ (29 162/188 142) and 12.8％ (27 888/217 877).The rate had decreased apparently from both 2012 and 2013 to 2014 (x2=217.6, P ＜ 0.01;x2=341.3, P ＜ 0.01).The CDRs of specialized hospitals for year 2012, 2013 and 2014 were 51.2％ (45 496/ 88 916), 50.6％ (45 853/90 607) and 49％ (55 404/113 105), while the CDRs of general hospitals for each year were 56.6％(50 851/90 054), 53.0％(51 656/97 535) and 48.6％(50 919/104 772).Both showed significant decreasing trend (x2=105.8 and 1 215.7, both P ＜ 0.01).The average CDR of general hospitals was obviously higher than that of specialized hospitals in 2012 and 2013 (x2=505.6 and 104.3, both P ＜ 0.01).However, the difference disappeared in 2014 (x2=3.2, P ＞ 0.05).The three main first indications of cesarean section were associated and postoperative pregnancy complications, and no medical indications.Interestingly, from 2012 to 2014, the CDR for scarred uterus in specialized hospitals raised from 5.4％ to 20.3％, and that in general hospitals increased from 6.7％ to 21.6％, which became the first.Conclusions The average CDR in Jiangsu Province tends to decrease each year, so does the CDR without medical indications.The first indication of cesarean section is associated or postoperative pregnancy complications, while scarred uterus becomes the most common in cesarean section.

Objective: To examine the relationship between clustering of metabolic disorders and left ventricular hypertrophy (LVH) in hypertensive children and adolescents, and to provide the reference for preventing the damage to their heart structure. Methods: Based on the data from the Twelfth Five-year National Science and Technology Support Program “Early Warning, Diagnosis and Treatment of Cardiovascular Disease in Children” from September 2012 to September 2014 in Jinan, 261 children and adolescents aged 6-17 years whose hypertensive status was confirmed based on appearance of elevated blood pressure across three different occasions were included. Covariance analysis was used to analyze the relationship of clustering of metabolic disorders with left ventricular mass index levels. Multivariable logistic regression model was used to examine the relationship of clustering of metabolic disorders with LVH. Results: After adjustment for sex, age and blood pressure, LVMI levels were (33.21±1.85) (38.57±1.19) and (43.00±1.63)g/m2.7, respectively, for hypertensive children and adolescents carrying 0, 1 and ≥2 metabolic disorders; LVMI levels increased with the number of metabolic disorders in hypertensive children and adolescents (P<0.01). Compared with the hypertensive children and adolescents without any metabolic disorders, the risk for LVH increased in ones carrying 1 and ≥2 metabolic disorders, the odds ratios and 95% confidence intervals were 2.41(1.11-5.23) and 4.69(2.05-10.74), respectively. Conclusion The clustering of metabolic disorders was positively correlated with the LVMI levels and risk of LVH in hypertensive children and adolescents. Therefore, to prevent cardiac damage such as LVH in hypertensive children and adolescents, it is important to prevent and control metabolic disorders comprehensively.

Objective: To examine the relationship between obesity and carotid intima-media thickness (cIMT) in children and adolescents in order to provide scientific evidence for the prevention and control of cardiovascular diseases. Methods: A total of 289 children and adolescents aged 6 to 17 years were included in the study, and weight, height, blood pressure and cIMT were measured. Multivariable Logistic regression model was used to analyze the relationship between obesity and cIMT. Results: The level of cIMT and prevalence of high cIMT in obese males were higher than those in non-obese males(P<0.05), while there was no statistical significance between two weight groups in females (P>0.05). After adjusted for sex, age and blood pressure, compared with the non-obese children and adolescents, the odds ratios (OR s) of obesity for high cIMT in total sample, males and females were 3.03 (95%CI=1.11-8.28), 4.32 (95%CI=1.23-15.21) and 1.45 (95%CI=0.23-9.37) respectively. Conclusion Obesity may increase cIMT levels and risk of high cIMT in children and adolescents. Effective measures should be taken to prevent and control the obesity, and to reduce the risk of abnormal vascular structure in children and adolescents.
