RESUMEN

Objective@#To investigate the relationship between V-raf murine sarcoma viral oncogene homologue B1 (BRAF)V600E mutation and metastasis after thyroidectomy in papillary thyroid carcinoma (PTC) with different recurrence risk stratification.@*Methods@#From March 2014 to September 2017, 134 PTC patients (45 males, 89 females; age: 16-72 years) who underwent 131I treatment in the Department of Nuclear Medicine of Liaocheng People′s Hospital and had undergone BRAFV600E mutation detection were retrospectively analyzed. The recurrence risk during surgery was divided into 3 levels: low-, medium- and high-risk. Each recurrence risk group was divided into 3 subgroups according to the postoperative follow-up results: non-metastasis group, cervical lymph node metastasis group and pulmonary metastasis group. BRAFV600E mutation rates in different groups were compared (χ2 test).@*Results@#The BRAFV600E mutation rate was 55.22%(74/134) in 134 PTC patients. The mutation rates were not significantly different in the 3 metastasis subgroups for low-risk patients (n=46; χ2=2.39, P>0.05). In medium-risk patients (n=47), the mutation rate in neck lymph node metastasis group (16/19) was higher than that in pulmonary metastasis group (3/8) and non-metastasis group (25.00%, 5/20; χ2 values: 5.89 and 13.75, both P<0.05), while there was no difference between pulmonary metastasis group and non-metastasis group (χ2=0.44, P>0.05). In high risk patients (n=41), the mutation rate in neck lymph node metastasis group (85.00%, 17/20) was higher than that in the pulmonary metastasis group (5/13) and non-metastasis group (1/8; χ2 values: 7.68 and 13.08, both P<0.01), while there was no difference between pulmonary metastasis group and non-metastasis group (χ2=1.64, P>0.05).@*Conclusion@#The BRAFV600E mutation is closely related to neck lymph node metastasis after operation in middle- and high-risk patients with PTC, but it does not significantly increase the probabilities of neck lymph node metastasis in low-risk patients and pulmonary metastasis in low-, medium- and high-risk patients.

RESUMEN

Objective:To summarize the major risk factors of infection in the process of cleaning and disinfection of endoscopy center in our hospital,and formulate the corresponding prevention measures to reduce the incidence of endoscopic infection so as to ensure medical safety of patients.Methods:The specialist check the cleaning disinfection process,statistics of each link in the risk factors of infection.600 endoscopes were taken at random after disinfection,endoscopic inner cavity and the outer surface samples are collected,the cleaning and disinfection of the test results for evaluating quality indicators.Results:Testing 600 samples of qualified 584,and the percent of pass is 97.3%,gastroscopy,colonoscopy,duodenum mirror,bronchoscope,endoscopic ultrasonography qualified rate was 98.6%,96.8%,95.6%,96.0%,97.2%,respectively.28 strains of pathogenic bacteria were detected in 16 cases of unqualified samples,including 13 strains of helicobacter pylori,7 strains of escherichia coli,4 strains of pseudomonas aeruginosa,2 strains of pseudomonas aeruginosa,1 strains of staphylococcus aureus,1 strains of Klebsiella pneumoniae;16 cases to detect unqualified reason analysis,scrub incomplete accounted for 37.5%,Not according to the instructions required to use multi-enzyme and disinfectant accounted for 18.75%,special infected patients did not do special treatment of endoscopy accounted for 12.5%,endoscopic insufficient drying and the staffhand hygiene is not up to standard accounted for 12.5%,respectively.Conclusion:Endoscopic cleaning and disinfection aspects of infection caused by many factors,infection control education should be strengthened for all personal in the endoscopy center,regular professional training of cleaning and sanitation personal,cleaning and disinfection process should be standardized management,establish traceability registration system,control the quality of the endoscope cleaning and disinfection from each link.It is the main measure to prevent digestive endoscopy center in infection.

RESUMEN

Objective To evaluate the value of technetium-99m methoxy isobutyl isonitrile(99Tcm-MIBI) tomography and integrated CT scan in preoperative localization diagnosis of primary hyperparathyroidism (PHPT). Methods 31 patients with PHPT were selected .15 minutes and 90 minutes ( delayed images ) after intravenous administration of 99 Tcm-MIBI 370 MBq, static anterior planar images of the neck and chest were obtained .99 Tcm-MIBI tomography and integrated CT scan were acquired after the delayed images .All patients received neck ultra-sound scan before surgery .The imaging findings were compared to the pathological results .Results The detec-tion rate of hyperparathyroidism lesions of 99 Tcm-MIBI dual-phase imaging and 99 Tcm-MIBI tomography and regis-tration with integrated CT scan was 87.1%and 93.5%respectively, without statistical significance (P>0.05). However , they were both higher than ultrasound scan which had a detection rate of 64.5%.The differences had statistical significance (χ2 =4.039 and 7.884 respectively , P<0.05 ) .The detection rate of parathyroid hyper-plasia of 99 Tcm-MIBI tomography and registration with integrated CT was both 80.0%, higher than that of the ul-trasound test(40.0%)and 99Tcm-MIBI dual-phase imaging(40.0%).The fusion imaging with integrated CT scan provided detailed anatomy data and more information for surgical doctors .Conclusions 99 Tcm-MIBI tomography and registration with integrated CT scan can improve the detection rate of PHPT compared with 99 Tcm-MIBI dual-phase imaging , provide detailed anatomy data , and has high clinical value in preoperative localization diagnosis of PHPT.

RESUMEN

OBJECTIVE To make the patients using the central venous catheter safely when given chemotherapy and intravenous nutritional therapy,and to decrease the catheter infection by establishing effective infection-preventing systems. METHODS Many infection-preventing actions were carried out,including a three-level management,improving the workers′ training in catheter operation and maintenance,and health education. RESULTS Comparing with the matched group,the infection rate of the experimental group was much lower after the actions.The actions prevented the increase of infection effectively. CONCLUSIONS Building and carrying out the systems are proved to be important measures to decrease the catheter infection and ensure the quality of life among patients during the therapy in hospital.
