ObjectiveTo evaluate the value of uhrasonography for arthrocentesis in the hip and the advance of the femoral head/acetabulum as the puncture location in patients without sonographically obvious joint effusion.Methods Forty-three patients diagnosed with ankylosing spondylitis or osteoarthritis were included,82 hip joints were involved and received ultrasounded-guided intra-articular injections.The puncture site was the joint space between the femoral head and the acetabulum.The times,depth,procedure time,side effects and complications of each injection were recorded.ResultsAll 82 hips could be explicitly displayed.The depths from the skin surface to the joint space were (3.4 ± 0.9)cm (left)and (3.1 ± 0.8)cm (right),respectively.Overall,100％ of hip joints were punctured successfully,and 95.1％ of them were succeeded with the first arthrocentesis.The procedure time was (287.9 ± 45.8) s.No side effects or complications were observed.ConclusionsThe sonographic technique could be used as a primary method of image guidance for performing hip arthrocentesis and the joint space between the femoral head and the acetabulum could be a choice of target location for the patients without joint effusion.

Objective To study the clinical characteristics,pathology,and treatment for papillary carcinoma of the breast.Methods The clinical data of 17 patients of papillary carcinoma of the breast admitted in the First Affiliated Hospital of Wen Zhou Medical College were retrospectively analyzed.Results Papillary carcinoma of the breast accounted for 0.64％ of all breast cancer cases hospitalized during last 10 years.All cases had palpable lumps in the breast.12 cases received modified radical mastectomy,2 cases received simple mastectomy,2 cases underwent breast conservation therapy,1 case underwent simple mastectomy plus sentinel lymph node biopsy.15 patients received postoperative chemotherapy,among those 5 cases also received radiotherapy.During a 32.5-month median follow-up ( 1 month to 8 years),one case with bone metastases died 2 years postoperatively and another one died of multimetastases 7 years later.Conclusions The prognosis of papillary carcinoma of the breast is closely related with its pathology type.For intraductal papillary carcinoma low-traumatic therapy is applicable,while in case of infiltrating papillary carcinoma or invasive micropapillary carcinoma ( IMPC ),more aggressive therapies like that adopted for infiltrating ductal carcinoma are recommended.

ObjectiveTo explore the sonographic features of gouty arthritis.MethodsThe sonographic features of gouty arthritis were summarized by retrospectively studying the sonogram of 19 joints of 5 patients.ResultsFive the first metatarsophalangeal joints,8 knees,2 ankles,2 elbows and 2 wrists were investigated.Out of 19 joints,17(89.4％) had double contour signs,a hyperechoic and irregular band over the superficial margin of the articular cartilage.Joint effusions were seen in 13 of 19 joints (68.4％).Multiple hyperreflective foci could be seen in the joint fluid,which were obvious by shaking the probe.In 19 joints,11 (57.9 ％) had proliferation of the synovium identified,and proliferative synovium were revealed as hyperperfusion or hypoperfusion by color Doppler ultrasound.In one knee,the synovium proliferated obviously with involved area about 5 cm × 2 cm,and hyperechoic aggregates with acoustic shadow could be seen in it.Articular cartilage became irregularly thin and the hyperechoic outline of subchondral bone cortex became rough or even broke in 6 of 19 joint (31.6％).H omogeneous,hyperechoic aggregates with or without acoustic shadow in the soft tissue around the joint were seen in four joints (21.1 ％).Three in these 4 joints exited bone cortex erosions adjacent to aggregates.ConclusionsGouty arthritis has some specific sonographic features,ultrasound maybe usefully discover this disease in early period.

Objective To evaluate the charateristics of biliary stricture after orthotopic liver transplantation(OLT) by ultrasound. Methods Diametes,thickness,characteristic echo of bile were observed by ultrasound in 41 patients with biliary stricture after OLT,and the results were compared with those of 46 patients without biliary complication after OLT.Results The diameter of intrahepatic bile,thickness of bile,incidence of intrahepatic bile dilation or hyperechogenicity in biliary stricture patiens were higher than those in patients without biliary complication,there were significant differences between two groups(P＜0.05).Conclusions The series of ultrasonographic character such as bile dilation,thickeness or hyperechogenicity of biliary wall,thin of bile duct are available to diagnose biliary stricture.

Objective To compare the value of contrast-enhanced ultrasound (CEUS) and conventional ultrasound (CUS) in the localization and definition of different types of uterine myomas.Methods With real-time CEUS technique, 56 patients with uterine myomas proved by pathology were observed. The accuracy between CEUS and CUS in the localization and definition of different types of uterine myomas was retrospectively analyzed. Results The accordance rates of CEUS and CUS in the diagnosis of total uterine myomas, intramural myomas, submueous and subserous myomas were 94.6% (53/56) vs 73.2%(41/56),99.3%(31/32) vs 78.1%(25/32) and 91.6%(22/24) vs 66.7%(16/24),respectively,and in the definition of number and margin of myomas were 92.8 % (104/112) vs 80.30% (90/112) and 91.9 (103/112) vs 78.6 % (88/112). The accordance rates of CEUS and CUS in the diagnosis of typical uterine myomas were 95.8% (23/24) and 87.5% (21/24),and in the diagnosis of atypical uterine myomas were 93.8%(30/32) and 62.5% (20/32),which were different in statistics (P<0.05). Conclusions CEUS is better than CUS in revealing the number and margin of different types of uterine myomas. The accordance rates of CEUS were higher than those of CUS in the diagnosis of different types of uterine myomas and atypical uterine myomas. CEUS may be a new technique in the localization and definition of uterine myomas.

Objective: To investigate the effects of epigallocatechingallate (EGCG) on lipid metabolism related gene and long non-coding RNA (lncRNA) expression proifle by biochip technology, and to explore the possible relationship between the two elements.
Methods: HepG2 cell was cultured with EGCG at 25μmol/L for 24 hours, the total RNA was extracted and hybridized into the biochip of Human Transcriptome Array 2.0 for mRNA and lncRNA expression profile analysis. Bioinformatics technology was used to establish the possible relationship between lncRNA and the predicted target genes;the data obtained from biochip microarray was conifrmed by real time RT-PCR examination.
Results: The microarray revealed that EGCG treated HepG2 cell expressed 27 differential lipid metabolism genes and 11 of them involved in cholesterol metabolism. In addition, there 285 lncRNA expressions were up-or down-regulated. Bioinformatics technology indicated that the predicted target genes for lipid metabolism might be cis-or trans-regulated by lncRNA;the data from real-time RT-PCR was consistent with the data from biochip microarray.
Conclusion: Tea polyphenols improves lipid metabolism and lncRNA might be involved in the regulation of lipid metabolism related gene.
