Objective To evaluate the imaging findings of congenital anomalies of inferior vena eava (IVC) with 64-slice spiral CT. Methods Between January 2008 and May 2009, 6986 patients who had routine abdominal 64-row multi-detector computed tornography were retrospectively analyzed for congenital anomalies of IVC. Results Among 6986 cases, 25 cases with congenital anomalies of IVC were identified. Six case were left IVC, showing IVC left to the aorta inferior to the renal hilum. Ten cases were double IVC, showing two IVC besides the aorta inferior to the renal hilum. Five cases were abnormal renal vein, showing retroaortic and circumaortic left renal vein. Two cases were IVC interruption with collateral circultion by azygous or hemiazygous vein, contrast-enhanced CT scan showing deficiency of the IVC between hepatic and renal hilums, the enlarged azygos vein communicating with IVC at renal level and the hepatice vein draining into the right atrium. Venography showed that IVC draining into the superior vena cava through azygous or hemiazygous veins. One case was interruption of the IVC with portal vein continuation, contrastenhanced CT scan showing the communication between the IVC and portal vein. One case was hemiazygos continuation of a left IVC, contrast-enhanced CT scan demonstrating dilatation hemiazygos continuation of a left IVC and jointed the azygos vein. Conclusion The 64-slice spiral CT can be a diagnostic standard for congenital anomalies of inferior vena cava.

Objective To explore the feasibility of excluding oral 75 g glucose tolerance test (OGTT)in pregnant women with fasting plasma glucose (FPG) ＜4.4 mmol/L in middle and late trimester.Methods From February 1,2012 to August 31,2013,18 851 pregnant women without pre-gestational diabetes mellitus who received 75 g OGTT in Maternal and Child Health Hospital of Hubei Province,China,at 24-28 weeks of gestation were enrolled.The criteria for gestational diabetes mellitus (GDM) were FPG ＞5.1 mmol/L and/or 1 h plasma glucose ＞10.0 mmol/L and/or 2 h plasma glucose ＞8.5 mmol/L in OGTT.The values of FPG in predicting GDM were analyzed with receiver operating characteristic (ROC) curve.The differences of detection rates for GDM among women of different ages,women with different FPG levels,and those with or without risk factors of GDM were compared by x2 test and Fisher's exact test.Results The overall detection rate of GDM was 9.11％(1 718/18 851).The detection rate of GDM was lower in women aged ＜ 25 years than women aged 25-,30-and ≥ 35 years [4.77％ (137/2 875) vs 7.76％ (803/10 350),12.43％ (552/4 440)and 19.06％ (226/1 186),respectively,x2=30.53,120.24 and 210.66,all P＜0.01].The sensitivity and specificity were 55％ and 68％,respectively,when the cutoff value of FPG was 4.4 mmol/L,and the Youden index was 0.23 and the area under the ROC curve was 0.61 (95％CI:0.59-0.63,P＜0.01).The sensitivity and specificity were 40％ and 80％,respectively,when the cutoff value was 4.5 mmol/L,and the Youden index was 0.20 and the area under the ROC curve was 0.61 (95％CI:0.59-0.63,P＜0.01).The missed diagnosis rate was lower when the cutoff point of FPG was defined as 4.4 mmol/L.The detection rate for GDM was 3.45％ (384/11 121) in women with FPG ＜4.4 mmol/L,significantly lower than in those with FPG ≥ 4.4 but ＜5.1 mmol/L and ≥ 5.1 mmol/L [8.06％ (561/6 957) and 100.00％ (773/773),x2=183.66 and 7 672.08,all P＜0.01].When FPG was ＜4.4 mmol/L or ≥ 4.4 but ＜5.1 mmol/L,the detection rate for GDM was significantly higher in women with GDM risk factors than in those without [5.09％ (118/2 318) and 10.75％ (184/1 712) vs 3.02％ (266/8 803) and 7.19％ (377/5 245),x2=23.56 and 22.06,P＜0.01].Conclusion OGTT may not be included in GDM screening in the pregnant women with FPG＜4.4 mmol/L and without GDM risk factors in the areas lack of medical resources.

Objective To investigate CT and MRI features of hepatic sclerosed hemangioma (HSH).Methods CT and MRI findings were retrospectively reviewed in 20 cases of HSH,all of which were confirmed pathologically after hepatic surgery.Twenty patients underwent CT scan,4 patients underwent MRI.Meanwhile,the enhancement pattern and signal intensity were analyzed either.Results Twenty patients showed main part of tumor was hypo-attenuating on CT plain scanning,and 16 patients showed the central area of tumor was markedly more hypo-attenuating on CT plain scanning.After administration of intravenous contrast media,multifocal linear or small nodular enhancement in the peripheral area was seen during the arterial phase on 16 patients of HSH.Venous phases showed centripetal enhancement or spread around the nodules enhancement which continued to delayed phases with low density of no enhancement in the lesion area.Four patients showed no obvious enhancement on arterial phases and slight separation sample enhancement at the edge or inside of the lesions with a wide range of non enhancement areas on venous phase and delayed phase.Four patients were performed MRI examination,the lesions demonstrated hypointensity with a lower signal area on T1WI,hyperintensity with a higher signal intensity area on T2WI.The DWI sequence of b value were 0,150,800 s/mm2,all of which were obviously hypointensity.The edge of lesions showed small nodular enhancement on arterial phase,irregular concentric enhancement on venous phase and delayed phase,and there was no enhancement area with lower signal in the center of the lesion.Conclusions The enhancement pattern of HSH different from cavernous hemangioma,with a larger non enhancement area in the center of the lesions and similar to other hepatic masses with central scar,differential diagnosis dependence on CT and MRI dynamic enhanced scan.

Ureteral stricture, urine leakage and other urinary complications are likely to occur after kidney transplantation, which severely affect the function of renal allograft and even lead to renal allograft loss. Ureteral stent plays a critical role in kidney transplantation, which could promote the urine flow from kidney to bladder after kidney transplantation, lower the pressure within the ureter and reduce the risk of early urinary complications. However, it may also cause urinary tract infection, stent-related complications and BK virus infection, etc. Therefore, clinicians should flexibly grasp the indications for ureteral stent removal. In this article, the application, potential adverse reactions and the timing of removal of ureteral stent in the field of kidney transplantation were reviewed, aiming to provide reference for clinical decision-making related to ureteral stent after kidney transplantation.

OBJECTIVETo study the early X-ray and CT findings of patients with severe acute respiratory syndrome (SARS).

METHODSChest radiography and CT were performed in 28 patients with SARS within one to three days after onset of the disease. CT examinations included conventional spiral CT and high-resolution CT (HRCT). The radiographic and CT findings of these patients were analyzed retrospectively.

RESULTSAbnormal CT findings were noted in all the patients, but abnormal chest radiographic findings in 17 cases (60.7%, 17/28). CT showed single small focal patchy opacities in 23 patients (82.1%, 23/28), including oval ground-glass opacities in 20 patients, lobular distribution ground-glass opacities in 2 and small patchy consolidation in one. Multi-focal ground-glass opacities were found in 2 patients and extensive opacities in three. In the 28 patients, a total of 31 lesions were found in the upper (7, 22.6%), middle (3, 9.7%), and lower lobes (21, 67.7%). The diameter of the lesions ranged from 20 to 35 mm.

CONCLUSIONThe dominant feature of early SARS patients is focal patchy opacity in the lung, and oval small ground-glass opacities are the common morphological findings on CT.

Previous studies proposed that the synergistic effect of fibroblast growth factor-21 (FGF-21) and insulin may be due to the improvement of insulin sensitivity by FGF-21. However, there is no experimental evidence to support this. This study was designed to elucidate the mechanism of synergistic effect of FGF-21 and insulin in the regulation of glucose metabolism. The synergistic effect of FGF-21 and insulin on regulating glucose metabolism was demonstrated by investigating the glucose absorption rate by insulin resistance HepG2 cell model and the blood glucose chances in type 2 diabetic db/db mice after treatments with different concentrations of FGF-21 or/and insulin; The synergistic metabolism was revealed through detecting GLUT1 and GLUT4 transcription levels in the liver by real-time PCR method. The experimental results showed that FGF-21 and insulin have a synergistic effect on the regulation of glucose metabolism. The results of real-time PCR showed that the effective dose of FGF-21 could up-regulate the transcription level of GLUT1 in a dose-dependent manner, but had no effect on the transcription level of GLUT4. Insulin (4 u) alone could up-regulate the transcription level of GLUT4, yet had no effect on that of GLUT1. Ineffective dose 0.1 mg kg(-1) FGF-21 alone could not change the transcription level of GLUT1 or GLUT4. However, when the ineffective dose 0.1 mg x kg(-1) FGF-21 was used in combination with insulin (4 u) significantly increased the transcription levels of both GLUT1 and GLUT4, the transcription level of GLUT1 was similar to that treated with 5 time concentration of FGF-21 alone; the transcription level of GLUT4 is higher than that treated with insulin (4 u) alone. In summary, in the presence of FGF-21, insulin increases the sensitivity of FGF-21 through enhancing GLUT1 transcription. Vice versa, FGF-21 increases the sensitivity of insulin by stimulating GLUT4 transcription in the presence of insulin. FGF-21 and insulin exert a synergistic effect on glucose metabolism through mutual sensitization.

Objective:To explore the value of 18F-fluorodexyglucose (FDG) PET/CT combined with integrated contrast-enhanced CT on the diagnosis of hepatic epithelioid hemangioendothelioma(HEH). Methods:Six patients (2 males, 4 females, age: (41.0±5.6) years) histopathologically confirmed to be HEH in Qingdao Central Hospital between November 2013 and November 2018 were retrospectively analyzed. All patients underwent 18F-FDG PET/CT dual-phase imaging and three-phase dynamic enhanced scanning with integrated CT. Characteristics of 18F-FDG PET/CT and contrast-enhanced CT images were classified and analyzed. Results:All 6 patients had multi-lesions (30 lesions in total). The capsule retraction sign was found in 16.7% (5/30) lesions, target sign was found in 33.3% (10/30) lesions, and " lollipop sign" was found in 13.3% (4/30) lesions. There were three ways of enhancement showed by CT: mild progressive enhancement, delayed enhancement, and black target sign/white target sign in the portal phase. Among the 30 lesions, 66.7% (20/30) had higher 18F-FDG uptake than liver parenchyma, with maximum standardized uptake value (SUV max) of 4.18±0.64 during routine imaging and 4.23±0.70 during delayed imaging, and the retention index was 0.65(-1.88, 4.60). The rest 33.3% (10/30) showed similar 18F-FDG uptake to liver parenchyma, with SUV max of 2.75±0.52 during routine imaging, and 2.78±0.55 during delayed imaging. The uptake of 18F-FDG increased with time in 22 lesions and decreased in 8 lesions. In the metabolically heterogeneous lesions, the relatively high-metabolization site was also the site with higher peak enhancement; in the lesions with uniform metabolism, the CT enhancement was also uniform. Bilateral pulmonary metastases were found in 2/6 patients. Conclusion:18F-FDG PET/CT dual-phase imaging combined with CT three-phase dynamic enhanced scanning is helpful in accurate diagnosis of HEH and could show extrahepatic metastases.

In order to obtain the lead compound for treatment of rheumatoid arthritis (RA), in this study, therapeutic efficacy of three bispecific antibodies (BsAB-1, BsAB-2 and BsAB-3) against both hIL-1beta and hIL-17 were compared on CIA model mice. First, by ELISA method we compared the binding capacity of the three bispecific antibodies to the two antigens. The results showed that all three antibodies could simultaneously bind both antigens, among these antibodies, BsAB-1 was superior over BsAB-2 and BsAB-3. CIA model was established with chicken type II collagen (CII) and developed RA-like symptoms such as ankle swelling, skin tight, hind foot skin hyperemia. The CIA mice were treated with three antibodies once every two days for total of 29 days. Compared with the CIA model mice, the RA-like symptoms of the antibody treated-mice significantly relieved, while the BsAB-1 treated-mice were almost recovered. CII antibody level in the serum and cytokines (IL-2, IL-1beta, IL-17A and TNF-alpha) expression in the spleen were examined. Compared with the CIA model mice, all three antibodies could significantly reduce CII antibody and cytokine expression levels. BsAB-1 antibody was more potent than BsAB-2 and BsAB-3. In summary, BsAB-1 is superior over BsAB-2 and BsAB-3 in amelioration of RA symptoms and regulation of CII antibody production and pro-inflammatory cytokine expression, therefore, BsAB-1 can be chosen as a lead compound for further development of drug candidate for treatment of RA.
