Objective To investigate clinical features,diagnosis and surgery treatment of Hashimoto thyroiditis associated with thyroid carcinoma. Method Twenty-four cases of Hashimoto thyroiditis diagnosed by surgical pathology from January 2004 to December 2009 were associated with thyroid carcinoma. Results In the all 24 cases,22 cases (91.7% ,22/24) were associated with papillary thyroid carcinoma,including 12 cases (50.0% ,12/24) of micropapillary thyroid carcinoma,and 2 cases (8.3%, 2/24) were associated with medullay thyroid carcinoma. Thyroid colour ultrasound Doppler indicated that diffuse enlargement of thyroid with nodes occurred in 21 cases,account for 87.5%(21/24), single node occurred in 15 cases,account for 62.5%(15/24), 12 cases demonstrated thyroid nodes with calcification,account for 50.0%(12/24). Eight cases were examinated by fine-needle aspiration cytology biopsy(FNACB) before operation,examing results of 3 indicated thyroid carcinoma, account for 37.5%. Twenty cases were followed up 2 months to 6 years,no thyroid carcinoma recurred,4 cases missed. Conclusions Thyroid colour ultrasound Doppler examination plays an important role in diagnosis of Hashimoto thyroiditis associated with thyroid carcinoma before operation. It is necessary to investigate progressively the role of FNACB in diagnosis of Hashimoto thyroiditis associated with thyroid carcinoma before operation. Surgical exploration might become an important approach in diagnosis and treatment of Hashimoto thyroiditis associated with thyroid carcinoma.

The purpose of this study was to identify specific microRNAs (miRNAs) during differentiation and maturation of interneurons and to predict their possible functions by analyzing the expression of miRNAs during in vitro differentiation of the rat interneuron precursor cell line GE6. In the experiment, the interneuron precursor cell line GE6 was cultured under three different conditions, i. e. the first was that had not added growth factors and the normal differentiation cultured for 4 days (Ge6_4d); the second was that cultured with bone morphogenetic protein-2 (BMP2) for 4 days (Ge6_bmp2); and the third was that cultured with sonic hedgehog (SHH) for 4 days (Ge6_ shh). In addition, another group of undifferentiated GE6 (Ge6_u) was applied as a control. We found in this study that the expression levels of a large number of miRNAs changed significantly during GE6 differentiation. The expression levels of miR-710, miR-290-5p and miR-3473 increased in the GE6 cells with secreted factor BMP2. These miRNAs may play important regulatory roles during interneuron differentiation.

OBJECTIVE To explore the method to prevent 203 patients after liver transplantation from infection.METHODS According to infective reason after liver transpantation,the strict management in every step was performed,including establishing standard of infection control,strengthening the staff management,and separating the different area.RESULTS Multi-organs dysfunction sydrome was found in 4 patients after liver transplantation because of fungal infection,and the total mortality of patients after transplantation was 1.97%.CONCLUSIONS Strengthening the nursing management can take a significant effect for patients after transplantation to control infection and decrease mortality rate.

Objective To compare the whole-body equivalent doses from volumetric modulated arc therapy (VMAT) and static intensity-modulated radiotherapy (IMRT) for patients with cervical cancer.Methods Nine patients with cervical cancer admitted to our hospital in 2014 were included in this study.Both VMAT and IMRT were planned for each patient.Each patient's personal dose equivalent (Hp (10)) was measured using thermoluminescent dosimeters placed at the xiphoid process and glabella during IMRT and VMAT.The whole-body equivalent doses were estimated based on the results measured at the xiphoid process and compared between the VMAT and IMRT techniques.The paired t test was used for difference analysis.Results The Hp (10) values measured at the xiphoid process and glabella of every patient were lower for VMAT than for IMRT.At a prescribed dose of 50 Gy,if the mean Hp (10) values measured at the xiphoid process were considered to represent the whole-body equivalent doses,the whole-body equivalent doses for VMAT and IMRT were 364 mSv and 538 mSv,respectively.Conclusions VMAT results in a lower whole-body equivalent dose to patients compared with IMRT.The decreased whole-body equivalent dose delivered by VMAT may reduce the likelihood of a radiation-induced secondary malignancy.

An adolescent patient,in the peak of growth and development,with severe skeletal Class Ⅲ malocclusion and maxillary impacted canines was treated by removable and fixed appliances in the upper and lower dental arches.After treatment,the crossbite was relieved,the facial contour was improved,the integrity of the denture was kept and the Class Ⅰ molar relationship was achieved.

Objective To compare the clinical efficacy and angiographic outcomes of balloon dilation angioplasty,balloon-expandable stent implantation and self-expanding stent implantation in the treatment of intracranial arterial stenosis.Methods The patients with intracranial arterial stenosis who met the indications of surgical intervention treated with balloon dilatation angioplasty and stent placement were selected from Nanjing Stroke Registry Program.According to the different interventional procedures,the patients were divided into the balloon expandable stenting goup,the self-expanding stents group and the balloon dilatation angioplasty group.The success rate of surgery,the perioperative complication rate and the significant residual stenosis rate were compared among the three groups.The clinical and angiographic assessments were performed through 1-,3-,6-,12- and 24-month regular outpatient or inpatient follow-up after procedure.The incidences of ischemic stroke and/or death and restenosis within 2 years were compared.Multivariate Cox proportional hazards analysis was used to analyze the risk factors for recurrent ischemic stroke and/or death and restenosis.Results A total of 183 patients with 192 stenoses performed balloon dilatation angioplasty or stenting,in which 92 were in the balloon expandable stenting goup,42 were in the self-expanding stents goup and 49 in the balloon dilatation angioplasty group.Their preoperative stenosis rates were 80.2 ±12.8％ 、76.3 ± 11.9％ and 89.7 ± 10.2％,respectively (F =15.863,P =0.000).There were no significant differences in other baseline data.The success rates of surgery in the balloon expandable stenting group,self-expanding stents group and balloon dilatation angioplasty group were 96.7％,95.2％ and 91.8％,respectively (x2 =1.646,P =0.439).The perioperative complication rates were 6.5％,14.3％ and 10.2％,respectively (Fisher exact test,P=0.334).The imaging follow-up showed that the restenosis rate in the balloon dilatation angioplasty group was 48.5％.Although it was high than 27.7％ in the balloon expandable stenting group and 34.8％ in the self-expanding stents group,there were no significant differences (x2 =4.176,P =0.124).Multivariate Cox proportional hazards analysis showed that balloon dilatation angioplasty was an independent risk factor for restenosis after procedure (hazard ratio 2.490,95％ confidence interval 1.247- 4.969,P=0.010).Conclusions Compared to the balloon expandable stenting,the balloon dilatation angioplasty is more likely to have restenosis,but it is not associated with the risks of postoperative recurrent ischemic stroke and/or death.

Objective To evaluate the curative effects of carbon nanoparticles on central lymphnode dis -section in papillary thyroid carcinoma ( PTC) .Methods 72 PTC patients were randomly divided into two groups:carbon nanoparticle group(n=32)and the control group(n=32).Patients in the carbon nanoparticle group were injected with carbon nanoparticles during surgery .Patients in the control group had conventional surgery .The number of lymph nodes being dissected ,lymph node metastasis , and the rate of hypoparathyroidism were compared between the two groups .Results The number of lymph nodes dissected in nanoparticle group ( n =312 ) was much bigger than that in the control group (n=189)(P<0.01;t=8.476).The incidence of hypoparathyroidism in nanoparticle group(n=1)was much lower than that in the control group (n=8)(P<0.05;χ2 =4.571).The metastasis of lymph nodes has no significant difference between the two groups (P>0.01;χ2 =1.048).Conclu-sions The lymphatic tracer technique may improve the number of lymph nodes dissected in central region of PTC and reduce parathyroid gland damage .

Objective To investigate the related factors of postoperative hypocalcemia after thyroid carc-er surgery.Methods 346 cases of thyroid carcer patients undergoing surgery from Jan .2013 to Dec.2013 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed .Results 129 cases developed hepocalcemia after thyroid surgery .Among the related factors that may cause postoperative hypocalcemia , the scope of surgery , parathyroid injury and secondary surgery might play important roles .Conclusions The inci-dence of postoperative hypocalcaemia is high after total thyroidectomy .Patients with reoperation and lymph node dissection have an increased rate of postoperative hypocalcaemia .In order to reduce hypocalcaemia incidence ,sur-gons need to protect parathyroid blood supply in thyroid surgery and give calcium after surgery .

Objective Through a two-year follow up program,this study was to analyze the urinary iodine frequency of a cohort in the intervention trial,concerning different doses of salt iodization,so as to explore the selection of appropriate concentration of salt iodization.Methods A multistage cluster sampling method was used to select three townships in two countries for community intervention with different doses [ ( 15 ± 5 ) mg/kg,(25 ± 5 ) mg/kg,( 35 ± 5 ) mg/kg ] of salt iodization.Results After intervention,the median of urinary iodine was reduced among the population.The urinary iodine frequencies of (15 ± 5) mg/kg and (25 ± 5) mg/kg among groups of children were mainly concentrated in 100-200 μg/L and 200-300 μg/L paragraphs in A county.While the 300 μg/Lparagraph had an overall decline in B county,the 100 μtg/L and 200 μg/L paragraph ratio increased but the trend seemed to be slow.The 100-300 μg/L paragraph of the four treatment groups took a larger proportion and kept smooth in a more ideal state.However,the control group still maintained at above 250 μg/L level.Conclusion The iodine supplementation should be gradually implemented in Chongqing.The doses of salt iodization should be reduced from the current (35 ± 15)mg/kg to (25 ± 5) mg/kg in the economically developed areas.At the same time,we need to continuously follow the changes of the condition.
