The patients in experimental group were given the treatment for traditional hemodialysis two or three times a week,combined with the treatment for resin absorption twice a month.The patients in the control group were only given the treatment for traditional hemodialysis two or three times a week.The middle molecular substance(MMS),beta(2) microglobulin(?_2-MG),blood urea nitrogen,creatinine,albumin,globulin,the counts of red blood,hemoglobin,the change of blood pressure and clinical manifestation of the patients were observed before and three months after the treatment respectively.Results The rates of clearance of MMS and ?_2-MG were significantly higher in the experimental group than those of the control group(P

Objective To investig the value of neck lymph dissection in re-operation for differentiated thyroid carcinoma (DTC) and direct the choice of re-operative pattern.Method Re-operation was performed in 122 cases with DTC,of which neck lymph dissection was performed in 88 cases and the clinical data were retrospectively analyzed.Of 88 cases,partial thyroidectomy was performed in 38 cases in the first operation,one lobe plus isthmus excision 16 cases,thyroiddectorny was perfomed in 2 cases,neck lymph nodes biopsy in 32 cases.Results 11 patients suffered from thyroid micro carcinoma.The metastasis rate of neck lymph node were 65.91% (58/88) and residual carcinoma rate was 31.59%(12/38). Conclusions Neck lymph dissection had definite curable effect on re-operation for DTC.Neck lymph dissection should be performed when tumor had involved capsule,enlarged lymph node was palpated in the neck and thyroid micro carcinoma was confirmed.Re-operation was necessary for recurrent thyroid carcinoma.Attention must be paid to the fullresection of recurrent lesions and preserving laryngeal nerve and parathyroid in re-operation.

Objective:To investigate the application value of real-time ultrasound elastography in the treatment of fibroids radiofrequency ablation (RFA).Methods:Transvaginal ultrasonography,Real-time ultrasound elastography (RTE) and contrast-enhanced ultrasonography (CEUS) were performed on 34 patients with a total of 38 uterine fibroids who had the treatment of RFA before,1 hour and 3 months after the treatment of RFA.Detected the diameters of the lesions with the three methods of CEUS,RTE and 2D.Analysed the elastic image features and divided into groups,Measured the elastic strain ratio and compared the E/E0 in and between the group.The difference of lesion diameter between 2D,RTE and CEUS was compared.When the image of lesions showed blue and green was taken as the cirterion of incomplete ablation after RFA,conpared with CEUS,analysed the consistency of RTE and CEUS in evaluating the degree of ablation.Results:The lesions were divided into 3 groups according to the preoperative elastic image,with 8 (21.1％) in the blue group,20 (52.6％) in blue-based and 10 (26.3％) in green-based group.The difference was obvious in E/E0 between the 3 groups before RFA.There was no significant difference in E/E0 between 1 hour and 3 months after RFA (P ＞ 0.05).In each group the E/E0 of lesions were significantly increased at 1 hour and 3 months after the treatment of FRA,and the hardness of 3 months after RFA was harder than that of 1 hour after RFA(P＜0.05).The diameter measured by RTE was larger than that by 2D and CEUS before RFA(P＞0.05).The diameter measured by 2D was larger than that by RTE and CEUS at 1 hour after RFA (P＜0.05).No statistically significant difference was found in the lesion diameters among the three methods of2D,RTE and CEUS at 3 months after the treatment ofRFA (P＞0.05).CEUS and RTE had the basic consistent in the evaluation of lesions ablation degree at 1 hour (kappa=0.46) and 3 months (kappa=0.54) after the treatment of RFA.Conclusions:After RFA,the myoma gradually hardens,and RTE can reflect the change of the hardness,RTE can clearly show the boundary of uterine ftbroids especially after the treatment of RFA,can be used in the prediction of lesions ablation degree,so there was a certain application value of RTE used in RFA.

Objective To evaluate the application of pure brilliance imaging(PB1) in diagnosis of benign and malignant breast neoplasms. Methods Ninty-seven breast neoplasms were respectively examined by high frequency ultrasound and PBI before operation,then correlated with pathological results. Results The accuracy of high frequency ultrasound for breast neoplasms was 73.2% with the sensitivity 77.8% ,specificity 69.2%. The detectable rate of spiculate margin, halo,calcification were much higher in PBI than those in high frequency ultrasound(P<0.05). And the accuracy,sensitivity and specificity of PBI were 86.6%, 91.1%, 82.6%. Conclusions PBI can significantly increase the detectable rate of ultrasonographie marginal features of breast neoplasms which were also helpful to the differential diagnosis.

Objective To investigate the diagnostic value of contrast enhanced ultrasound in breast cancer. Methods Thirty-six cases including 51 typical and 22 atypical breast cancer were examined with injecting contrast agent before operation. The enhanced charaters of perfusion pattern, enhanced level, and modes were observed and reanalyzed when pathology was got. Results There was no statistical meanings in perfusion pattern, enhanced level and mode between typical and atypical breast cancer. They all enhanced like branch or annulus with high lever and there were 3 enhanced modes:"fast in slow out"(48% ,35/73) ,"lastly fast in slow out"(44% ,32/73) and "same in same out"(8% ,6/73). Conclusions The enhanced modes of breast cancer showed "fast in slow out" , "lastly fast in slow out"and "same in same out", enhanced like "branch or annulus" and high level enhanced. Contrast enhanced ultrasound can increase the diagnostic accuracy in the early stage of breast cancer.

Objective To describe and analyze the clinical characters of patients with FRG from 7 Chinese families.Then analyze and identify their mutations in SGLT2 gene,and explore the association of genotype and phenotype.Methods Quantitative test for 24-hour urine glucose and other laboratory tests were carried out among 7 probands (14 patients in all) and their family members from 7 pedigrees (totaling 23 subjects).All coding regions,including intron-exon boundaries,were analyzed using PCR followed by direct sequence analysis.Results Five novel mutations in SLC5A2 gene were identified in this investigation,including four missense mutations (A Serine to Glycine at position 335 (c.1003A＞G,p.S335G),a Glutamine to Arginine at position 448 (c.1343A ＞ G,p.Q448R),an alanine to proline at position 474 (p.A474P,c.1420G ＞ C) and a glycine to aspartic acid at position 580 (c.1739G ＞ A,p.G580D) and a deletion in intron 7 (c.886(-10_-31)del).By the minigene studies using the pSPL3 plasmids,we confirmed the deletion c.886(-10_-31)del as a splicing mutation.In this study,the mutation c.886(-10_-31)del accounted for about 43％ of the total alleles (12/28).These patients with compound heterozygous or homozygous mutations manifested middle degree or severe glycosuria (Quantitative test for 24-hour urine glucose:10.56-50.68 g/1.73 m2),however those with heterozygous variants presented with mild to moderate glycosuria (Quantitative test for 24-hour urine glucose ≤ 2.45 g/1.73 m2).This fits co-dominant inheritance pattern.Conclusions Five novel mutations which may be related to FRG are found in this study,and c.886(-10-31) del may be a high frequency mutation in Chinese patients.

Objective To investigate the current situation of thyroid disease by analyzing retrospectively the color poppler ultrasonography data of neck discomfort in Heilongjiang Province.Methods A total of 13 020 cases (18-93 years old) of thyroid ultrasound examination data collected from September 2009 to October 2012 at the Department of Ultrasound,Fourth Affiliated Hospital of Harbin Medical University,were retrospectively analyzed.According to the sonographic features of thyroid (thyroid morphology,size,echo characteristics,blood flow,nodular location,number,calcification,etc),combined with ultrasound diagnosis,the relationships between gender and disease,age and disease,ultrasound diagnosis and disease classification,gender,number of nodules and benign and malignant were analyzed.Results Among the 13 020 cases,524 cases was excluded.There were 2 291 male cases; abnormalities were detected in 1 679 cases,and the abnormal ratio was 73.29％; there were 10 205 female cases; 7 946 cases were abnormal,and the abnormal ratio was 77.86％.The proportion of abnormal thyroid cases of the total number of female was higher than that of male,and the ratio of male and female was 1.00 ∶ 4.73 (1 679∶7 946); gender differences were statistically significant(x2 =18.476,P ＜ 0.01).There were nodular type 5 018 cases,diffuse type 2 012 cases and mixed type 2 603 cases in sonographic findings.The nodular type on ultrasound images showed mainly nodular goiter(79.21％,3 975/5 018).The diffuse type on ultrasonic images showed mainly Hashimoto Thyroiditis(59.24％,1 192/2 012).The mixed cases on ultrasound images showed mainly nodular goiter (89.83％,2 331/2 595).Ultrasound diagnostic results showed that nodular goiter accounted for 65.52％ (6 306/9 625) and Hashimoto Thyroiditis accounted for 17.97％ (1 730/9 625).Proportion of thyroid disease increased gradually with age,reached a peak [29.93％(2 557/8 544) and 28.84％ (2 464/8 544)] between the ages of 41-50 and 51-60 years old.The proportion gradually decreased into[14.17％(1 211/8 544),7.26％(620/8 544)] between the age of 61-71 and ＞ 71 years old.The incidence differences of malignant nodules between different age groups were statistically significant (x2 =407.796,P ＜ 0.01).Among malignant nodules,solitary nodule accounted for 95.76％ (113/118) ; multiple nodules accounted for 4.24％ (5/118),and there were more solitary nodule than multiple nodules(x2 =15.286,P ＜ 0.01).About malignant solitary nodules,women accounted for 87.61％(99/113); men accounted for 12.39％ (14/113),and women's were significantly higher than man's(x2 =360.960,P ＜ 0.01).Correlation analysis showed that the results of ultrasounddiagnosisofvarious thyroid diseases were highly correlated with the ultrasonic types of diseases(r =0.139 99,P ＜ 0.01).Conclusions Nodular goiter and Hashimoto Thyroiditis are the most common adult neck discomfort diagnosed by ultrasound in Heilongjiang Province.The high-risk age of thyroid disease is between 41-60 years old.Thyroid malignant is more common in single nodular,and the number of female patients is significantly higher than that of men.
