Objective To explore the application of adaptive statistical iterative reconstruction (ASIR)scanning technique in low dose pediatric cervical CT, especially in reducing the radiation dose for thyroid. Methods We retrospectivly analyzed 140 pediatric cervical CT. 70 cases of group A scaned with ASIR technology and preseting noise index 12 HU in Discovery CT 750 HD (GE Healthcare), and 70 cases of group B scaned with filtered back projection (FBP) technology and preseting noise index 14 HU in VCT 64 (64 Lightspeed VCT, GE Healthcare). The other scan parameters were same in 2 groups. The distribution characteristics of gender and age were completely consistent between groups. The minimum current, the maximum current, the current of thyroid on CT images and CT dose volume index (CTDIvol), scanning length and dose length product (DLP) on dose reports were all recorded for each child. The noise values of CT images were measured. 4 scores standard was used to evaluate the subjective image quality. The data were analyzed with SPSS 13, Kappa method for the test of consistency and t test for the differences of the measured data. Excel was used for mapping. Results The minimum current, the maximum current, the average current, the current for thyroid of the two groups were respectively (26.8 ± 4.2), (43.2 ± 15.4)mA;(35.8±9.6),(41.8±13.6)mA;(34.6±8.6), (41.0±13.2)mA;(36.8±12.3), (44.7±21.0)mA. The CTDIvol, DLP and the scanning length of the two groups were respectively(1.3 ± 0.3), (1.8 ± 0.6)mGy;(29.0 ± 8.3), (40.3 ± 15.6) mGy·cm and(157.5±20.2), (157.6±21.8)cm. The average current, the thyroid current, CTDI and DLP in group A were 15.8%, 17.9%, 27.3%and 28.4%lower than those in group B (t=-5.50—-0.02, P<0.01). The subjective image quality scores of the two doctors were respectively 3.4 ± 0.9, 3.3 ± 1.0, they were highly consistent (Kappa=0.834, P<0.01). The objective image noise of cancellous bone and neck muscles were respectively (32.5 ± 5.3),(32.9 ± 5.1)HU and (9.2 ± 2.3), (9.1 ± 2.0)HU, there were not statistically difference between the two groups (t=-0.47—0.24, P<0.05). Conclusion Compared with FBP, low dose pediatric cervical CT with 30%ASIR could provide dose reduction for thyroid and the whole neck while maintaining diagnostically acceptable images .

Objective To evaluate the efficacy and safety of the interventional techniques for emergent treatment of iatrogenic renal injuries.Methods Nine patients with iatrogenic renal vascular injuries were treated with superselective renal arterial embolization.The causes of renal injury included post-renal biopsy in 5 patients,endovascular interventional procedure-related in 2,post-renal surgery in 1,and post-percutaneous nephrostomy in 1 patient.The patients presented clinically with hemodynamical unstability with blood loss shock in 7 patienrs,severe flank pain in 7,and hematuria in 8 patients.Perirenal hematoma was confirmed in 8 patients by CT and ultrasonography.The embolization materials used were microcoils in 7 and standard stainless steel coils in 2 patients,associated with polyvinyl alcohol particles(PVA)in 5,and gelfoam panicles in 2 cases.Results Renal angiogram revealed intra-renal arteriovenous fistula in 6 cases,intrarenal pseudoaneurysm in 2 cases,and the contrast media extravasation in 1 patient.The technical success of the arterial embolization was achieved in all 9 cases within a single session.All angiographies documented complete obliteration of the abnormal vessels together with all major intrarenal arterial branches maintaining patent.Seven patients with hemodynamically compromise experienced immediate relief of their blood loss related symptoms,and another 7 with severe flank pain got relief progressively.Hematuria ceased in 8 patients within 2-14 days after the embolization and impairment of renal function occurred after the procedure in 5 cases,including transient aggrevation(n=3)and developed new renal dysfunction(n=2).Two of these patients required hemodialysis.Perirenal hematoma were gradually absorbed on ultrasonography during 2-4 months after the procedures.Follow-up time ranged from 6-78 months(mean,38 months),4 patients died of other primary diseases of renal and multi-organ failures.Five patients are still alive without further intervention,and suffering no more of rebleeding and deterioration of renal function.Conclusions Transcatheter selective renal arterial embolization is safe and effective in the treatment of iatrogenic renal vascular injuries,resulting in permanent cessation of bleeding.(J Intervent Radiol,2007,16:807-810)

Objective To describe the manifestations of the inferior phrenic arteries(IPA)supply to the pulmonary hemorrhagic lesions and to evaluate the safety and efficacy of transcatheter arterial embolization(TAE)of the IPA.Methods The clinical data and imaging findings of eighteen patients with the additional blood supply to the pulmonary hemorrhagic lesions from the IPA were evaluated retrospectively.The causes of the bleeding were lung malignancies in 9,bronchiectasis in 7,and chronic inflammation in 2 patients.TAE supplementally was performed in patients with IPA supply to the pulmonary lesions,using polyvinyl alcohol particles,gelatin sponge particles,and microcoils.Results Selective arteriogram demonstrates an enlarged IPA,with numerous branches and hypervascularity in all 18 cases, with tumor staining in 9,the contrast material extravasation in 6,and non-specific staining in 2 cases.In addition,IPA-to-pulmonary shunting was found in 9 cases.All the lesions supplying by IPA were adjacent to the pleurae,including adjacent to the diaphragmatic pleura in 11,the mediastinal pleura in 5,and the lateral pleura of the lower lobe in 2 cases.Technical success of IPA embolization was achieved in the 18 cases.Embolization of other nonbronchial systemic arteries(the internal thoracic artery in 7 and intercostal artery in 3)was performed at the same session.All bleeding ceased immediately after supplemental IPA embolization.Follow-up time ranged from 8 months to 4 years.Mild recurrent hemoptysis occurred in 3 patients at 1,2,6 months respectively,after the embolization.These patients were responsive to conservative management.Recurrent bleeding did not occur in 15 patients during the follow-up. Conclusion The pulmonary hemorrhagic lesions,especially adjacent to the diaphragmatic and mediastinal pleurae,can be supplied by IPA,and may result in clinical failure following BAE.Supplemental TAE of IPA is a safe and effective adjunct to BAE in the management of bronchial bleeding supplied by IPA.

Objective To investigate the diagnosis and the relationship between its clinicopathological characteristics,treatment and the prognosis of primary colorectal lymphoma.Methods The clinical data of 20 primary colorectal lymphoma patients who received operative treatment in the past 34 years in our hospital were retrospectively summarized,and the influence of treatment and each clinicopathological factor on prognosis was assessed.Results Tumor size,lymph node metastasis,invasion of neighboring organs and distant metastasis,and type of operative treatment were significantly related to the survival(P0.05).Conclusions Diagnosis of primary colorectal lymphoma before operation is difficult,and misdiagnosis is common.Operative treatment is the main therapeutic means for colorectal lymphoma.Radical operation combined with chemotherapy can gain a good prognosis.

Objective:To investigate the effects of different lipid-lowering regimens on blood lipids, endothelial function and safety in patients with unstable angina.Methods:Patients who admitted to Henan Provincial People's Hospital for unstable angina from September 2018 to May 2019 were randomly (random number) divided into the conventional treatment group, intensive statin group and intensive lipid-lowering group. Follow-up was performed at 1, 3, and 6 months after treatment according to the predetermined lipid-lowering regimen. Assessments included lipid profile, liver function, muscle enzymes, hypersensitive C-reactive protein (hs-CRP), endothelial function (reactive hyperemia index, RHI), ischemic events, myalgia, and discontinuation. The differences of the follow-up indicators among the three groups were analyzed.Results:A total of 375 patients were enrolled and randomly divided into three groups, 125 patients in each group. There were no significant differences in demographic data and medication among the three groups. At the 1st month, the low density lipoprotein cholesterin (LDL-C) compliance rate of the intensive statin group was significantly higher than those in the conventional treatment group ( χ2=3.939, P=0.047) and the intensive lipid-lowering group ( χ2=4.63, P=0.031). At the 3rd month, the reductions of LDL-C in the intensive statin group and the intensive lipid-lowering group were significantly better than that in the conventional treatment group( P<0.01). At the 6th month, the reduction rate of LDL-C in the intensive lipid-lowering group was higher than that in the intensive statin group ( q=4.332, P<0.01). At the 1st month, the improvement of hs-CRP and RHI in the intensive statin group was significantly better than that in the conventional treatment group( q=4.133, P<0.05). From the 3rd month of treatment, the incidence of cardiovascular events in the intensive statin group and the intensive lipid-lowering group showed a tendency to decrease compared with the conventional treatment group, but no statistically significant difference was found. At the 6th months of treatment, the withdrawal rates were significantly higher in the intensive statin group and the intensive lipid-lowering group than that in the conventional treatment group (χ 2=4.488, P=0.03 and χ2=5.039, P=0.02). There were no significant differences in the ratio of liver enzyme and muscle enzyme elevation and the incidence of myalgia among the three groups (all P>0.05). Conclusions:Intensive statin therapy can make LDL-C reach the standard in patients with unstable angina pectoris as soon as possible, significantly improve inflammation indicators and endothelial function, and has good safety.

Objective To investigate the distribution of death among human immunodeficiency virus/acquired immuno deficiency syndrome(HIV/AIDS) cases in Guizhou Province from 1995 to 2017. Methods The HIV/AIDS death cases from 1995 to 2017 were downloaded from “Chinese National Comprehensive HIV/AIDS Prevention and care Information system” in Guizhou Province and were analyzed. Results From 1995 to 2017, Guizhou Province reported a total of 43 794 HIV/AIDS cases and 11 527 deaths according to current address. After excluding missing persons, the HIV/AIDS mortality rate of the province was 29.8%. The proportion of reported HIV/AIDS cases died in the same year ( 21995-2012=139.5, P<0.001; 22012-2015=28.2, P<0.001) and the proportion of HIV/AIDS cases ( 21995-2012=109.1, P<0.001; 22012-2014=57.2, P<0.001) who survived at the beginning but died later in the year all showed a trend being low-high-low. In the analysis of the detection history of death cases, the detection proportion of cluster of differentiation 4(CD4) T-cell and the proportion of antiviral treatment had been increasing year by year. The analysis of the cause of death found that the proportion of death caused by AIDS increased firstly and then declined, and the proportion of death due to excessive drug abuse showed a trend of declining year by year. Conclusions The mortality rate of HIV/AIDS in Guizhou Province was still high, and decreased rather slow. Expanding the coverage of HIV monitoring and screening is one of the key tasks of AIDS prevention and control. CD4+T-cell testing and free antiviral treatment should be strengthened to reduce the mortality rate of HIV/AIDS in Guizhou Province in the future.
