Objective To investigate the correlation between specific features on contrast-enhanced CT and its clinical findings of adrenal tuberculosis so as to improve the diagnostic accuracy of the disease. Methods Contrast-enhanced CT features in 30 patients with documented adrenal tuberculosis were retrospectively evaluated blindly for the features of location,size,morphology,attenuation and enhancement patterns on CT images,and compared with clinical and pathological materials.Results The common CT manifestations were as follows:enlargement of the adrenal glands in all 30 cases(bilateral 90%,mfilateral 10%)including mass-like enlargement in 13 cases and enlargement but the contours preserved in 17 cases, heterogeneity(28 cases,93.3%),calcification(17 cases,56.7%),and low attenuation in the center with peripheral enhancement(16 cases,53.3%)of the lesions.After antituberculosis chemotherapy, 5 cases of enlarged adrenal glands decreased in size or returned to normal size and configuration,with disappearance of the central low attenuation and new appearance of dot-like calcification in 2 cases.Cochran Armitage trend test showed there was an increasing tendency of calcification rate with clinical duration(X~2= 7.47,P

We report here on a 64-year-old woman with extramedullary plasmacytoma involving the bilateral adrenal glands. Primary adrenal extramedullary plasmacytoma is extremely rare and only three cases of extramedullary plasmacytoma in the unilateral adrenal gland have currently been reported on. This case is of interest in that the bilateral adrenals were involved. In this article, we present the MRI findings and we briefly review the relevant literature.

OBJECTIVETo screen low molecular weight protein biomarkers relevant to portal vein tumor thrombi (PVTT) in serum of hepatocellular carcinoma (HCC) patients.

METHODSSerum samples were obtained from 12 healthy volunteers, 12 HCC patients without PVTT and 12 HCC patients with PVTT. Using two-dimensional gel electrophoresis (2-DE) in which the second dimension was 16% SDS-PAGE, serum protein images of the 3 groups were analyzed by ImageMaster software. The differential protein spots were further identified by MALDI-TOF MS/MS.

RESULTSComparing the results using 12.5% SDS-PAGE gel, there were more protein bands (between 3 x 10(3) and 20 x 10(3)) and low molecular weight (MW) protein spots (less than 20 x 10(3)) were clearly shown in the 16% SDS-PAGE gel. Fifteen differential protein spots representing 5 proteins were found in the 3 groups by inter-class comparison and they were then identified. Compared with those in the healthy group, apolipoprotein A-I, lipoprotein CIII, transthyretin and DNA topoisomerase II were all down regulated in HCC groups and haptoglobin-2 was over expressed. All 5 proteins decreased more in the PVTT group than in the non-PVTT group.

CONCLUSIONThe expression of low MW serum protein obviously changes in the beginning and in the progressive stage of HCC, and differentially expressed low MW proteins might be potential biomarkers in an early prognostic prediction and surveillance in the treatment for HCC and PVTT.

OBJECTIVETo evaluate the efficacy of hepatitis B viruse (HBV) vaccination and its influencing factors among children in rural area of Jiangsu province.

METHODSTwenty-five hundred and twenty-two children born after 1998 in rural area were selected as the study population using multistage cluster sampling method. HBsAg and anti-HBs were detected by enzyme linked immunoassay (ELISA) and radio-immunoassay (RIA), respectively. Anti-HBs negative children were boosted using different hepatitis B vaccines and the efficacy was compared. Factors causing HBV infection in HBsAg positive children were also investigated.

RESULTSHBsAg positive rates in 1-7 year olds were 0.28%-1.28%, and the anti-HBs positive rates decreased from 76.7% to 45.5%. The HBsAg positive rate in children not timely vaccinated was significantly higher than those with HBV vaccine injection within 24 hours after birth (1.4% vs. 0.5%, P = 0.031). More than 90% of the anti-HBs negative children had protective level of anti-HBs after boosted with HBV vaccine.

CONCLUSIONHBsAg positive rate in children born after 1998 in rural area of Jiangsu province decreased significantly, with an average of 0.8%. The reason for HBsAg carriage in children might be attributed to mother-to-infant transmission or not timely HBV vaccination.

OBJECTIVETo study clinical effects of PHILOS (proximal humeral internal locking system) plates through mini-open deltoid-splitting approach for the treatment of proximal humeral fractures.

METHODSFrom March 2006 to August 2010, 22 patients with proximal humeral fractures were treated with PHILOS plates through mini-open deltoid-splitting approach. According to Neer classification, 6 cases were type II, 15 cases were type III and 1 case was type IV. Through the anterolateral approach to the shoulder, anterolateral vertical incision of 4 cm length was perforrmed from 1 cm under acromion, and separated deltoideus muscle vertically to touch the fracture,reduced the end of fracture directly and indirectly. PHILOS plate was inserted downward into anterolateral surface of humerus through deltoideus muscle, the distal end and proximal end was fixed by locking screws. The Neer score for shoulder function was evaluated within 1 year after operation.

RESULTSThe operative time ranged from 30 to 70 minutes with an average of 45 minutes. No blood transfusion was required during the operation, and all incisions healed in stage I. All the patients were followed up, and the duration ranged from 6 to 18 months with a mean time of 12.5 months. All the fractures healed up perfectly, and the union time ranged from 6 to 12 weeks. According to Neer criteria for shoulder joint function, 10 patients got an excellent result, 9 good, 2 poor and 1 bad. There were no complications such as axillary nerve injuries, screw loosening, steel plate breakage, dislocation of shoulder joint and necrosis of humeral bone.

CONCLUSIONPHILOS plate through mini-open deltoid-splittin approach for the treatment of proximal humeral fractures has follow advantages: simple recover,minor-injuries and small tissue invasion, which is an ideal method to treat proximal humeral fractures.

Porcine reproductive and respiratory syndrome virus (PRRSV) non-structural protein 7 (Nsp7) plays an important role in the induction of host humoral immune response and could serve as an ideal antigen for serological genotyping assay for PRRSV based on the significant difference in immunoreactivities of North American (NA) and European (EU) PRRSV Nsp7. In this study, Nsp7 of NA and EU PRRSVwas separately expressed and purified using prokaryotic expression system. The purified recombinant Nsp7 proteins reacted with serum antibodies against corresponding genotype PRRSV in Western blotting. However, nonspecific reaction of whole recombinant Nsp7 with antibodies against another genotype PRRSV was observed, indicating that whole NA PRRSV Nsp7 and EU PRRSV Nsp7 have similar antigenic epitopes and recombinant proteins could not be used for genotyping of antibodies against PRRSV. Based on the analysis of similar antigenic epitopes at the hydrophilic region of NA PRRSV Nsp7 and EU PRRSV Nsp7 by bioinformatics assessment, partial Nsp7 gene region deleted sequences encoding similar antigenic epitopes was constructed by fusion PCR. The recombinant truncated Nsp7 (NA-deltaNsp7 and EU-deltaNsp7, about 43 kDa) was expressed and the molecular weight was about 43 kDa. The results of Western blotting showed that NA-deltaNSP7 and EU-deltaNSP7 could be specifically recognized by positive serum to NA or EU PRRSV individually and nonspecific reaction was eliminated. This study provided a basis for further development of serological genotyping assay for North American and European genotype PRRSV infection.

OBJECTIVETo investigate the clinical value of gnome-wide chromosome microarray (CMA) technique in genetic etiological diagnosis of fetal cerebral ventriculomegaly.

METHODSA retrospective analysis was conducted in 109 women with singleton pregnancy, who were admitted in Nanfang Hospital with the diagnosis of cerebral ventriculomegaly in the fetuses by ultrasound between January, 2014 and December, 2016. Routine karyotype analysis and chromosome microarray analysis were performed to identify the chromosomal abnormalities in the fetuses.

RESULTSKaryotype analysis detected chromosomal abnormalities at a rate of 12.84% in these fetuses, significantly lower than the rate of 26.60% with CMA technique (P=0.004); the combined detection rate of the two techniques was 28.44%. In 17 cases, karyotype analysis yielded normal results while CMA microarray showed abnormalities with an extra abnormal detection rate of 15.60%. Among the 17 fetuses with chromosomal abnormalities, 6 had micro-deletion, 9 had micro-duplication, 1 had both micro-deletion and micro-duplication, and 1 had heterozygous loss of single parent diploid.

CONCLUSIONCMA technique can be used to detect abnormal chromosomal copy numbers in fetuses with cerebral ventriculomegaly to increase the detection rate of chromosomal abnormalities and facilitate prenatal consultation and prognostic evaluation.
