Objective: To describe the status of cognition about colorectal cancer and the screening and its relevant factors among first degree relatives of hereditary colorectal cancer patients in Guangzhou. Methods: Totally 274 subjects were investigated by a self-designed demographic questionnaire and the Chinese version of Cognitive Questionnaire for Colorectal Cancer and were analyzed by chisquare test, rank sum test and logistic regressive. Results: 60.2% (165/274) cases had a high level of cognition about colorectal cancer, 23.7% (65/274) had middle level of cognition about colorectal cancer and 16.0% (44/274) had a low level of cognition about colorectal cancer. Multivariate logistic regression analysis showed that age, sex, degree of education, marital status, family income, medical insurance and the number of cancer patients in his family were related factors (P<0.05). People who were young, female, highly educated, high family income, single, public/urban health insurance, commercial insurance and with more than 4 relatives suffering from colorectal cancer have higher cognitive level. Conclusions The level of cognition about colorectal cancer among first degree relatives of hereditary colorectal cancer patients was a little high. Medical staff should pay attention to relevant factors of health belief in subjects and develop targeted intervention to improve the level of cognition among these subjects and to promote their screening behavior.

Objectives To investigate the relationship between the expression of hENT1 protein in pancreatic cancer and the efficacy,adverse reactions and prognosis of gemcitabine.Methods The tissues of 83 patients with pancreatic cancer diagnosed in Department of Hepatobiliary and Pancreatic Surgery of Jiaxing Second Hospital and Jiaxing City Hospital of Traditional Chinese Medicine from June 2013 to January 2016 were collected by endoscopic fine needle aspiration biopsy.The expression of hENT1 protein was detected by immunohistochemistry,which was divided into hENT1 low expression group and high expression group.According to the curative effect of chemotherapy,it was divided into gemcitabine effective group and drug resistance group.The clinicopathological parameters,adverse reaction rate,median survival,and progressionfree survival (PFS) were compared between the two groups.Results Of the 83 pancreatic cancer tissues,37 (44.6％) had high expression of hENT1 and 46 (55.4％) had low expression.There were no significant correlations of the efficacy of gemcitabine chemotherapy with gender,age,clinical symptoms,primary tumor location,tumor size,TNM staging,CA19-9 level,CEA level,presence or absence of liver metastasis,but gemcitabine resistance rate in high expression group was significantly higher than the low expression group (78.1％ vs 50.0％),and the difference was statistically significant (P =0.010).Both groups were able to tolerate adverse reactions of gemcitabine chemotherapy and no chemotherapy-related death was observed,but the incidence of leucopenia and thrombocytopenia in hENT1 low expression group was significantly higher than those in bENT1 protein high expression group (63.0％ vs 21.6％,47.8％ vs 16.2％),the differences was statistically significant (all P ＜ 0.05).The median survival and 1-year PFS of hENT1 protein low expression group were significantly lower than those of high expression group (11 months vs 15 months,19.4％ vs 50％),and the differences were statistically significant (P ＜0.05).Conclusions Decreased hENT1 protein expression in pancreatic cancer tissue could reduce the efficacy of gemcitabine chemotherapy,increasing the incidence of leucopenia and thrombocytopenia.

Objective To evaluate the effect of intraoperative warming on delirium during emergence from general anesthesia in elderly patients.Methods Eighty elderly patients of both sexes,aged ≥ 65 yr,of American Society of Anesthesiologists physical status Ⅰ-Ⅲ,scheduled for elective total hip replacement,were assigned to routine group (group R,n=40) and warming group (group W,n=40).The non-operated site was covered using the sterile cloth,and no other active warming measurements were given in group C.Fluid was infused and warmed to 37 ℃,the non-operated site was covered using the forced-air warming system,and the temperature of the forced-air warming system was maintained at 38-42 ℃ in group W.The tympanic membrane temperatures was recorded at 5 min after anesthesia induction,at 30,60 and 90 min after beginning of surgery,at the end of surgery and at 30 min after emergence from anesthesia,and the difference between monitored values and monitored values on admission to operating room (△ T) was recorded at each time point.The intraoperative volume of fluid infused,operation time,extubation time,duration of postanesthesia care unit stay and development of delirium during emergence and shivering were recorded.Results Compared with group R,△T was significantly decreased at 60 and 90 min after beginning of surgery,the incidence of delirium during emergence and shivering was decreased,the extubation time and duration of postanesthesia care unit stay were shortened in group W (P＜0.05).Conclusion Intraoperative warming can decrease the development of delirium during emergence from general anesthesia and is helpful in improving the quality of recovery from anesthesia in elderly patients.

Objective To explore the characterization of thyroid stimulating hormone receptor(TSHR) gene mutational spectrum in children with hyperthyroidism from Guangzhou. Methods Ninety children were diagnosed with hyperthyroidism from July 2009 to July 2014 in our institute. Their median age at diagnosis was(7.5± 3.4) years, and there were 28 males and 62 females. Mutational analysis were performed by performing polymerase chain reaction (PCR) and DNA direct sequencing of exon 10 of TSHR gene. TSHR gene mutations from 50 unrelated healthy children were served as controls. The correlation between TSHR gene and hyperthyroidism in children was explored. Results A total of 3 mutations were identified in ninety children who were diagnosed with hyperthyroidism, one synonymous mutations(p.V614V), and two missense mutations( p. R707W and p. D727E). Mutation of p. V614V do not change amino acid and do not influence the structure and function of TSHR, no pathogenicity. p.R707W is a SNP associated with human cancers. The frequency of C allele of the D727E in children with hyperthyroidism was 86.7%, while 55.0% in the controls, significant different between the children with hyperthyroidism and the controls( P＜0. 01). In this study, a very high association between the D727E SNP and hyperthyroidism ( OR=18. 86, P＜0. 01) was found. Conclusion Three different mutations of TSHR gene exon 10 were identified in 90 children with hyperthyroidism, (c.1842A＞G,p.V614V、c.2119C＞T,p.R707W、c.2181G＞C,p.D727E), there were association between p.D727E and hyperthyroidism, nor p. V614V and p. R707W. Finally, p. D727E may be correlated with hyperthyroidism in children.

Objective This study aimed to assess the diagnostic value of anti-mutated citrullinated vimentin (MCV) antibodies in rheumatoid arthritis (RA) and its correlation with disease progression, extra-articular manifestations and overlap syndrome. Methods Retrospective Studies. Clinical data of 837 patients in PekingUnionMedicalCollegeHospitalfrom June to August 2017 were collected, including the result of anti-MCV, anti-cyclic citrullinated peptide (anti-CCP) antibodies, rheumatoid factor (RF), erythrocyte sedimentation rate (ESR) and High-sensitivity-C-reactive protein (CRP). According to the 1987 American College of Rheumatology classification criteria for rheumatoid arthritis, there were 323 patients diagnosed with RA, including 59 males and 264 females with the average age of 51 years. According to whether the RA patients have overlap syndrome with other autoimmune disease (AID) or have extra-articular manifestations, 258 cases were categorized into RA group, including 47 males and 211 females with the average age of 50 years; 14 cases were categorized into the group of overlap syndrome, including 1 male and 13 females with the average age of 36 years;51 cases were categorized into the group of extra-articular manifestations, including 11 males and 40 females with the average age of 59 years.According to 2010 rheumatoid arthritis classification criteria for destruction in joints, the radiographic changes were divided into 4 stages. There were 203 casesenrolled in our study, 88 caseswere fitted into early stage group (stage I)including 21 males and 67 females with the average age of 48 years; 115 caseswere fitted into progressive stage group, which compromisedstageⅡ (interim stage), stage Ⅲ (severe stage) and stage Ⅳ(final stage) cases, including 19 males and 96 females with the average age of 53 years. Mann-Whitney U test, x2 test, Receiver operating characteristic (ROC) curves and Spearmancorrelation coefficientwere used in Statistical analysis. Results Ⅰ Amongdiagnosed RA patients, 199 (61.6％) cases were positive for anti-MCV, anti-CCP and RFsimultaneously, 42 (13％) cases were positive for anti-MCV, which was higher than anti-CCP positive (1 cases, 0.3％) or RF positive (7cases, 2.2％). The difference was statistically significant(P<0.001, P<0.001). ⅡROC was calculated and MCV=35.95 U/ml was used as best-fit cut-off value. The AUC for anti-MCV was 0.867, while the sensitivity was 80.5％and specificity was 80.9％.ⅢThe detection levels of anti-MCV (682.8 (106.4-1000.0)), anti-CCP (407 (4.0-1536.0)) and RF (82.8 (21.1-244.9)) in the group of progressive stage were higher than those in the group of early stage (114.5 (28.5-1000.0), 62.5 (5.0-1020.7), 50.1 (6.7-127.1)), which showed a significant difference(P<0.05, P<0.05, P<0.05). The anti-MCV, anti-CCP and RF were positively related to the degree of joint destruction (r=0.229, P<0.05;r=0.187, P<0.05;r=0.167, P<0.05);anti-MCV and anti-CCP were positively related to extra-articular manifestation (r=0.152, P<0.05;r=0.136, P<0.05). Conclusion Anti-MCV antibodies are more sensitive in patients with RA, and have complementary diagnostic value for anti-CCP and RF-negative patients; high levels of anti-MCV and anti-CCP in RA patients are associated with RA progression and extra-articular involvement.

For the treatment of early non-small cell lung cancer, surgery is still one of the most important curative treatments. Lung segment or subsegment resection under video-assisted thoracoscopic surgery is becoming more and more popular. With the development of radiotherapy technology, Stereotactic Body Radiotherapy (SBRT) has achieved the similar or the same curative effect as surgery. It has become an indisputable curative treatment for patients who can not or refuse surgery, and there are still some disputes among those who can operate. Therefore, this review will elaborate on these treatment methods in order to help update the concept and provide more treatment methods and obtain more benefits for patients. Although it is no randomized clinical trial to compare SBRT with surgery, we suggest that SBRT is the curative treatment for patients who can not or refuse surgery. Especially for the elderly, or patients with cardiopulmonary diseases, diabetes and other high-risks. SBRT should become the main treatment methods, because its curative effect is not inferior to surgery and its complications are fewer and lighter. Therefore, for the treatment of non-small cell lung cancer in the early stage, it is more importent to choose individualized treatment methods so as to more benefit.

Objective: To evaluate the safety and effectiveness of repeated transcranial magnetic stimulation (rTMS) for treating non-fluent aphasia after stroke. Methods: Forty-five stroke survivors with non-fluent aphasia were randomly divided into a 0.5 Hz group, a 1 Hz group and a sham group, each of 15. In addition to routine linguistic training, the three groups were given rTMS over the inferior frontal gyrus of the right hemisphere at the corresponding frequency or sham stimulation. Before as well as 5 and 10 days after the treatment, all of the subjects were evaluated using the Chinese version of the Western Aphasia Battery (WAB). The occurrence of adverse events was also observed. Results: Before treatment, no significant differences were observed in the groups′ average aphasia ratio, spontaneous speech, listening comprehension, retelling and naming using the WAB. After 5 and 10 days significant increases were observed in the average WAB scores of all three groups, but the listening comprehension of the 0.5 Hz group was significantly better than that of the sham group 10 days later, as was the spontaneous speech of the 1 Hz group. Conclusion rTMS at either 1 Hz or 0.5 Hz can improve the linguistic functioning of stroke survivors with non-fluent aphasia. Both 0.5 Hz and 1 Hz rTMS are safe, but the latter is more effective.

Objective: To explore the effect of PDCA nursing model combined with token reward on the compliance and negative emotions of children with hypospadias. Methods: A total of 120 children with hypospadias who were admitted to Children′s hospital affiliated to Zhengzhou University from February 2017 to December 2017 were selected as study subjects. According to the time of admission, they were divided into observation group and control group, with 60 cases in each group. The control group was given routine nursing care, the observation group was given PDCA nursing mode combined with token rewards intervention on the basis of routine care. The self-made children's behavioral compliance assessment table was used to compare the compliance of the two groups of children. Achenbach Child Behavior Check List (CBCL) scores were performed before and after the intervention. The hospitalization time and the incidence of complications were calculated. Results: There was no significant difference in CBCL scores between the two groups at admission (t=0.965, P=0.102). The scores of compliance and CBCL scores of the observation group were (43.12±3.99) points and (17.62±7.30) points respectively, the scores of control group were (30.67±4.53), (24.23±6.67), the difference was statistically significant (t=15.977, 5.184, P<0.01). The hospitalization time and complication rate of the observation group were (18.73±0.84)d, 15.00% (9/60), which were significantly lower than (20.92±1.90) d, 31.67% (19/60) of the control group, and the difference was statistically significant (t=8.166, χ²=4.658, P<0.01 or 0.05). Conclusions The PDCA nursing model combined with token reward can improve the compliance of children with hypospadias and improve their negative emotions.

Objective: To observe the effect of clean water perineum nursing in preventing urinary catheter-associated urinary tract infection. Methods: From October 2015 to October 2016, 160 patients with indwelling urinary catheter were selected from the first affiliated Hospital of Shantou University Medical College, ICU and neurosurgery ICU. According to the order of admission, the patients were randomly divided into experimental group and control group. A total of 80 patients in the experimental group received clean water perineal nursing, while 80 patients in the control group received routine perineum nursing with 0.5% iodophor. The incidence of urinary tract infection was compared between the two groups on day 3rd, 7th and14th after indwelling urethral catheter. Results: In the control group, the incidence of urinary tract infection on day 3rd, 7th and14th was 0, 1.3%(1/80) and 5.0%(4/80), respectively. In the experimental group, the incidence of urinary tract infection on day 3, 7 and 14 was 0, 2.5% (2/80) and 3.8%(3/80). The difference was not statistically significant (χ²=0.340, 0.149, P> 0.05). Conclusions Using clean water perineum nursing does not increase the incidence of urinary tract infection. This method is simple, effective, and has no adverse reactions. It is worth popularizing in clinic because it can reduce the consumption of iodophor disinfectant and reduce the workload of nurses.

Objective: To evaluate the effect of biofeedback training on bowl function among rectal cancer patients with chemoradiotherapy and temporary enterostomy. Methods: Using randomized controlled trial design, 109 rectal cancer patients were randomly divided into three groups, the first blank control group, the second group pelvic floor muscle exercise group, the third group biofeedback group. High resolution anorectal manometry was used for 6 longitudinal traces in 16 months. Data of bowel function were collected by Memorial Sloan Kettering Cancer Center (MSKCC) Bowel Function Instrument. Results: The main effect of the change of five indicators, anal resting pressure, rectal resting pressure, maximum squeeze pressure, maximum squeeze time and high pressure zone, was time. The other four indicators, rectal volume at first senory, rectal volume at sense of convenience, maximal tolerable rectal volume and rectal compliance, among patients of biofeedback group were (32.71±5.00) ml, (74.26±8.30) ml, (188.40±12.68) ml, (5.69±1.18) ml/kPa and (68.09±6.38). The rectal volume at first senory, rectal volume at sense of convenience, maximal tolerable rectal volume and rectal compliance, among patients of biofeedback group were significant higher than blank control group and pelvic floor muscle exercise group (F=3.589-26.826, P<0.05). Conclusion The biofeedback could significantly improve the sensory indicators of patients with middle and low rectal cancer. High-resolution anorectal manometry could effectively evaluate the effect of biofeedback training in patients with middle and low rectal cancer.
