Objective To explore the causes of congenital hypothyroidism by single photon emission computed tomography(SPECT) thyroid imaging.Methods Nineteen cases with congenital hypothyroidism were collected,and SPECT thyroid imaging was performed 15 minutes late after injected 99m TcO_ 4- 18.5-37.0 MBq.Results Five cases were found with normal glands,1 case with enlarged thyroid, 2 cases with enlarged thyroid and increased radiation,4 cases with ectopic thyroid,4 with a hypogenetic thyroid,and the last 3 cases showed no thyroid imaging.Conclusions The causes of congenital hypothyroidism can be found by SPECT thyroid imaging,which is important to the diagnosis of congenital hypothyroidism combined with detection of T_3,T_4,TSH.

Objective To evaluate the diagnostic value of 99mTc-dimercaptosuccinate acid(DMSA) renal cortical scintigraphy for the identification of distinguishing between upper urinary infection(UUTI) and lower upper urinary infection(LUTI).Methods Two hundred and seventy-five children (111 males,164 females)ranging from 44 days to 15 years old,presented with urinary tract infection underwent 99mTc-DMSA renal cortical scintigraphy.The images were scored as normal (indicating LUTI) and abnormal (indicating acute pyelonephritis or renal scarring).Results Of 275 children with UTI,95 cases had normal images diagnosed as LUTI,41 males,54 females;and 180 cases had abnormal images,70 males,110 females.One hundred and seventy-four cases were diagnosed as acute pyelonephritis,6 cases were diagnosed as renal cortical scars,56 cases were single renal involved and 118 cases were both renal involved,and 22 cases repeatedly underwent renal cortical scanning after therapy.Sixteen of 18 cases with acute pyelonephritis completely recovered normal or obviously ameliorated after 0.5 to 2.0 years,2 cases did not show any improvement after 0.5 to 1.5 years,4 cases with renal scarring,and showed little change on repeated images after 1.0 to 1.5 years.Conclusions The 99mTc-DMSA renal scintigraphy is very useful in differentiating the children with urinary tract infection.It also can be used to determine the extension,degree and nature of UUTI,and might play an important role in the treatment and follow-up observation in children with UUTI.

Objective To investigate the effects of mindfulness training on cancer related fatigue (CRF) in patients with breast cancer .Methods Two hundreds young and middle‐aged patients with breast cancer receiving chemotherapy in our hospital from January to June 2015 were divided into the observation group and control group ,100 cases in each group .The control group was given the routine nursing ,while on this basis the observation group was given the mindfulness training .The cancer related fa‐tigue status was evaluated according to the CFS scale .The CFS various dimensions and total fatigue scores before and after inter‐vention were compared between the two groups .Results The fatigue status existed in most of patients with breast cancer after chemotherapy ,the occurrence rate of CRF was 97 .0% ,which was dominated by moderate fatigue ,followed by mild fatigue ,severe fatigue was minimal ;the body fatigue ,cognitive fatigue ,emotional fatigue and total fatigue scores in the second time of chemothera‐py had no statistically significant differences between the two groups (P>0 .05);in the fourth and sixth time of chemotherapy ,the body fatigue ,cognitive fatigue ,emotional fatigue and total fatigue scores in the observation group were significantly lower than those in the control group ,the differences were statistically significant (P<0 .05) .Conclusion The mindfulness training interven‐tion can relieve the fatigue status and improve the living quality of the patient .

The mainly antigenic sites for the adenovirus neutraliation are present on Loop1 and Loop2 of hexon.Majority research were focus in the human adenovirus.Little was known on infectious canine hepatitis virus (ICHV), which was also called canine adenovirus typeⅠ.Here,ICHV (the isolated strain) DNA was isolated and purified from the cultured MDCK cells.The Loop1 and Loop2 fragments were amplified by polymerase chain reaction(PCR) method,and then was connected by ligase T4.The target fragment was then connected with vector pET28a.The nucleotide sequence ecoding Loop1 and Loop2 was determined.The nucleotide sequence identity of Loop1 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 100%, 100% and 83.8%, and the nucleotide sequence identity of Loop2 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 88.1% , 88.1% and 99.3%, and amino acid identity is 93.6%, 93.6% and 98.6%.The recombinant Loop protein was expressed in E.coli and was approximately 36kDa in size,and then was purified. Then BALB/c mice were injected subcutaneously in the back and armpit with the recombinant Loop protein.The anti-ICHV antibody titers of immunized serum was tested by indirect ELISA and the titers were up to 1:320.Western blot demonstrated that immunized sera could specifically combine with ICHV. The research laid a foundation for creating new genetic engineering products of infectious canine hepatitis virus.

Objective To explore the imaging manifestations of low-grade central osteosarcoma (LGCOS) and discuss their pathological features.Methods Twelve patients of LGCOS proved by surgery and pathology were analyzed retrospectively and a review of related literature was performed.All twelve patients had plain X-ray,1 1 patients CT examination,and 10 patients contrast-enhanced MR scan.Imaging features of the LGCOS were summarized,their clinical and pathological manifestations were discussed for differential diagnosis.Their prognosis was evaluated with followed up examination.Results Of the 12patients with LGCOS,six tumors were located in the distal femur,3 in the proximal tibia,2 in the proximal femur and 1 in the talus.The radiographic features of LGCOS were variable.There were 7 patients with predominantly osteolytic destruction,3 patients with mixed sclerotic and lyric changes,with well-defined margins,2 patients with Osteogenic changes on X-ray.On CT,9 patients showed a clear cortical breach,5 patients with soft tissue involvement,6 patients with peripheral incompletely sclerotic zone,2 patients with periosteal reaction.On MRI,there were 10 patients with abnormal signal in medullary cavity,8 patients with soft tissue masses,and all 10 patients exhibited contrast enhancement.The microscopic features of LGCOS were characteristically bland,comprising spindle cells arranged in interlacing fascicles in a heavily collagenous background with variable bone or osteoid production.There were mild nuclear atypia and rare mitoses.In four patients,misdiagnoses were made by biopsy or surgical pathology as fibrous dysplasia or fibrous histiocytoma and other benign lesions,all four patients had postoperative recurrence.Conclusions LGCOS should be differentiated form fibrous dysplasia,non-ossifying fibroma,and other benign lesions.An accurate diagnosis can be made in most cases by careful pathological and radiological correlation.

AIM:To investigate the effects of seipin gene deficiency on renal injury and the possible mecha-nisms in seipin-/-mice.METHODS:Six-month-old male seipin knockout ( seipin-/-) and wild-type ( WT) mice ( n=8) were used to study 24 h urinary albumin excretion ( UAE) , renal functions, pathological changes, and plasma leptin and adiponectin levels.Seipin mRNA expression in different tissues and each part of the kidney was also measured in WT mice.RESULTS:Real-time PCR analysis showed seipin mRNA expression in WT mice was higher in adipose tissue and testicles, and was also found in the kidney, which was mainly in glomeruli.Compared with control group, seipin-/-group showed increased kidney weight/tibia length (P<0.01), 24 h UAE (P<0.01), creatinine clearance (P<0.01), and glomerular and mesangial surface area (P<0.05).Both plasma leptin (P<0.01) and adiponectin (P<0.05) levels were significantly decreased in seipin-/-mice.CONCLUSION:Seipin gene deficiency in mice leads to renal injury prob-ably by decreasing plasma leptin and adiponectin levels due to lack of adipose tissue.

Objective To evaluate the correlation between cerebral blood volume and permeability surface by using muhislice CT perfusion imaging with glioma grade.Methods Ninteen patients with gliomas underwent conventional MR and multislice CT perfusion imaging preoperatively.These patients were divided into low grade and high grade groups which were correspond to WHO Ⅱ grade gliomas and WHO Ⅲ or Ⅳ grade gliomas respectively.CT data were transferred to on-line working station and processed to obtain time-signal curves,color perfusion maps and calculated perfusion parameters,including cerebral blood volume(CBV),cerebral blood flow(CBF),mean transit time(MTT)and permeability surfaces (PS)in tumoral parenchyma.Kruskal-Wallis test and correlation of CBV and PS was assessed by using SPSS 11.0 software.Results The median of CBV and PS in low-grade and high-grade glioma were 2.7, 6.5 ml/100 g;0.389,12.810 ml?100 g~(-1)?min~(-1),respectively,corresponding t value were 12.907, 13.500 with P
