Objective To compare the different effect of two gastric tube insertion methods in pa-dents undergoing computed tomographic virtual endoscopy. Methods 56 patients undergoing computed tomographic virtual endoscopy were randomly divided into group A and B according to gastric tube insertion methods, group A inserted gastric tube to descending duodenum by gastroscope, group B inserted by Jag precursor via nose. One- time success rate and the incidence rate of side effect were compared between the two groups. X2 test was adopted. Results One- time success rate of group A and B was 33.3%, 82.9% respectively, with obvious statistic difference. The incidence rate of side effect of group A was higher than that of group B. Conclusions Inserting gastric tube to descending duodenum by Jag precursor via nose is convenient, time- saving, causing less pain and resulting in higher success rate.

Gut microbiota is essential to human health,playing a major role in the bidirectional communication between the gastrointestinal tract and the central nervous system through the immunological,hormonal,neural and metabolic pathways.The colonization of the gut microbiota is influenced by multiple and diverse factors,such as the perinatal factors,dietary habits,diseases and antibiotics.The infant is the critical period for modifying the gut microbiota,disruptions during this period of microbiota-host interaction have the potential to affect the development and function of the brain.To regulate the homeostasis of the gut microbiota has its profound influences on improving the symptoms of gastrointestinal and behavior disorders.

Kimura's disease is a rare, benign, slow-growing chronic inflammatory swelling with a predilection for the head and neck region and is almost always with peripheral blood eosinophilia and elevated serum IgE levels. It is endemic in Asian males and rare in Western people. Surgical excision of the lesion is the first line therapy. Drug and radiation therapy have to be considered for the refractory lesions.

Objective To investigate the urinary iodine level and the thyroid function of early pregnant women in Qingdao,to explore the relationship between the iodine nutritional status and hypothyroidism.Methods 326 early pregnant women (<12 gestational weeks)were collected.The urinary iodine concentration and serum thyroid stimulating hormone (TSH),free thyroxine (FT4 ),thyroid peroxidase antibody (TPOAb)were detected. Results The median of urine iodine of pregnant women was 176.57μg/L,and the ratios of iodine deficient,iodine adequate,iodine more than adequate and iodine excessive groups were 3 8.65%,41.10%,15.95% and 4.30%.The total ratio of innormal urine iodine was 58.9%(192 /326).The differences between the ratios of the iodine deficient group,iodine excessive group and iodine adequate group both had statistically significant(χ2 =4.308,P <0.05;χ2 =4.826,P <0.05 ).There was no effect of iodine intake levels on serum thyroid peroxidase antibody.Conclusion There is no iodine deficiency among early pregnant women in Qingdao,but still individuals expose iodine deficiency.Iodine deficiency and iodine excessive are the risk factors of hypothyroidism during early pregnancy women,so we commend to detect the urinary iodine level.

OBJECTIVE To investigate the occupational hazard situation among medical staff and conduct effective measure and enhance the medical care.METHODS A questionnaire survey on occupational hazard had been completed among the hospitals in Fengtai District in Beijing in three years.RESULTS The rate of sharp damage of medical staff was 72.13%,from them the nurses were with highest rate(81.49%).The higher rate of sharp damage was in the operating theater(88.32%)and the surgical department(82.49%).CONCLUSIONS To assure the medical safety,we should pay more attention to the occupational hazard management.

Objective To investigate the application value of real clinical case centered situation simulation examination model in clinical medicine. Methods Two classes were randomly selected from 2008 grade clinical medicine majors, respectively as test group(n=158) and control group(n=156). Final examination of test group includes usual performance, case-oriented situation simulation examination (COSSE) and final written examination. Traditional methods were used in control group. The same paper was used in final written examination of the two groups. Scores of written examination and question-naires were used to evaluate the COSSE model. Data were processed using SPSS 16.0 statistical software;t and chi-square tests were used to analyze the data;P<0.05 signifies that the difference is statistically sig-nificant. Results Scores of final examination in test group were higher than those in control group(P<0.001). Times of independent completion of history taking, physical examinations and medical record writing were more in test group than in control group(P=0.002,0.017,0.048). Conclusions Contents and methods of COSSE is conducive to improving student's professional comprehensive ability.

Objective To explore the technique and feasibility of using 1.5 T MR guided radiofrequency ablation (RFA) of hepatic malignant tumor. Methods Twenty three patients with 44 malignant lesions in liver confirmed by pathology were treated with 1.5 T MR guided RFA using MR compatible multipolar RF electrode. Only patients refusing open surgery or suffering from unresectable lesions were included. Of these, 11 patients had primary hepatic carcinoma and 12 patients had hepatic metastases. The mean maximal diameter of lesions was (3.3 ± 1.8)cm. Postoperative MR was performed; the ablation zone covered and exceeded 0.5 to 1.0 cm to the margin of initial tumor was considered successful. Results All ablations were successful and lesions created by radio frequency were large enough to cover the initial tumor volume in all cases. No severe complications such as biliary fistula, perforation of diaphragmatic muscle,postoperative jaundice and pneumothorax were encountered. The mean operative time was (93 ± 33 ) min.The RF electrodes appeared in MRI as low signal structure. The ablation lesions were well-defined hyperintensity in T1 WI and hypo-intensity with a thin rim of high signal intensity on T2WI and DWI. Conclusion 1.5 T MR guided RFA of hepatic malignant tumor is an effective and safe technique.

Objective To discuss the effeet of nursing intervention in the prevention of psychiatric disorder in patients after coronary artery bypass grafting (CABG). Methods Patients with CABG(202 cases) were divided into the control group (100 cases) and the intervention group (102 cases).The control group received routine treatment and nursing while the intervention group was given systemic nursing intervention.The mental status was evaluated by mini-mental status examination (MMSE). Results The incidence of psychiatric disorder in the intervention group was 4 cases (3.92%),which was statistically lower than those in the control group(16 cases,16.00%). Conclusions Effective nursing intervention combined with effective treatment could prevent and control the psychiatric disorder of patients after CABG.

Objective To discuss the value of nursing work in 64-slice CT urography. Methods 240 patients participated in the 64-slice CT urography, inquiring medical history and iodine allergic history, paying attention to their psychological state and finishing iodine preliminary test before examination, ob-serving patients carefully, pre-judging any possible adverse effect and formulating corresponding measures during the examination, giving expectant treatment according to the various condition and nursing instruc-tion. Results 239 patients passed through the examination smoothly, agents exosmosis happened in one case and led to failure, but satisfactory image was obtained after rescanning. Conclusions Nursing oper-ation penetrates every step of 64-slice CT urography, which is a non-traumatic, low-expense and high-safety examination. Effect nursing directly influences the accuracy of the results, proficient nursing opera-tion and patient psychological nursing is the important part of it.

Objective To investigate the expressions of DKK1,SFRP4 and Wnt1 in cervical squamous cell carcino-ma(SCC), and the clinical significance thereof. Methods There were 76 samples of cervical squamous cell carcinoma were included in SCC group and 36 benign uterine resection specimens were control group (NC). The immunohistochemical meth-od was applied to detect the expressions of DKK1,SFRP4 and Wnt1 in two groups. Results The expression of DKK1 was significantly lower in SCC group than that in NC group (P＜0.05). The expression levels of SFRP4 and Wnt1 were significant-ly higher in SCC group than those of NC group (P＜0.05). There were significant differences in the expressions of DKK1, SFRP4 and Wnt1 between samples of different clinical staging, differentiation, sizes of tumor and lymph node metastasis (P＜0.05). The expression of DKK1 was negatively correlated with SFRP4 and Wnt1 in SCC group (P＜0.05). The expression of SFRP4 was positively correlated with Wnt1 in SCC group (P＜0.05). Conclusion The roles of SFRP4 and Wnt1 are syn-ergistic interactions in the development of SCC. DKK1 is an inhibiting factor of SCC.
