ObjectiveTo explore the clinical characteristics and radiological manifestations of immune reconstitution inflammatory syndrome(IRIS)in acquired immunodeficiency syndrome(AIDS)patients with tuberculosis(TB)during highly active antiretroviral therapy(HAART).MethodsThe clinical and radiological data in 4 AIDS patients with TB who presented IRIS were analyzed retrospectively.ResultsThe clinical presentations of IRIS in 4 patients included fever(4 cases),weakness and weight loss(3 cases),abdominal pain(2 cases),cough with sputum(1 case),dyspnea(1 case).Cervical and(or)supra-clavicular lymph node enlargement were seen in 3 patients,inguinal lymph node enlargement in 1 patient,abdominal lymph node enlargement in 1 patient,hilar or mediastinal lymph node enlargement in 2 patients,pulmonary parenchyma and liver were involved in 2 patients,the involvement of kidney,adrenal gland,mesentery,peritoneum,psoas,brain and cutis was respectively found in 1 patient.The clinical and radiological presentations of IRIS were temporary and self-limited,improvement can be seen with antituberculosis therapy and HAART. ConclusionsIt is possible to have IRIS during HAART in AIDS patients with TB.Imaging examinations play an important role in the early diagnosis,monitoting and evaluating the response to therapy of IRIS.

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.

OBJECTIVE:To investigate the effec ts of angiotensin receptor neprilysin inhibitor (ARNI)sacubitril valsartan sodium(SVS)on the short-term prognosis of patients with acute anterior myocardial infarction (AAMI)complicated with acute cardiac insufficiency. METHODS :A total of 80 patients with AAMI and Killip grade Ⅱ-Ⅳ of cardiac function ,who met the inclusion criteria ,were randomly divided into ARNI group and control group ,with 40 patients in each group. Both groups were given the same basic standardized drug treatment ,vital signs support treatment and percutaneous coronary intervention treatment at the same time. On this basis ,ARNI group was given SVS tablet orally ,with initial dose of 25 mg each time ,twice a day ; thereafter,gradually adjust the dose to 200 mg each time ,twice a day. Control group was given Enalapril maleate tablets orally , with an initial dose of 5 mg each time ,twice a day ;thereafter,gradually adjust the dose to 10 mg each time ,twice a day. Both groups took medicine for a long time ,and were followed up after 1,3 and 6 months of medication to the clinic. The levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), soluble growth stimulation expressed gene 2 protein (sST2) and echocardiography indexes were compared between 2 groups before and after medication. The 6-minute walking test (6MWT)and the incidence of cardiogenic readmission events were recorded in 2 groups after medication. RESULTS :Compared with before treatment,the indexes of the two groups were significantly improved at 1,3 and 6 months after treatment (P<0.05). Compared with control group ,the levels of NT-proBNP and sST 2 in ARNI group decreased significantly (P<0.05),the levels of left ventricular ejection fraction and 6MWT increased significantly(P<0.05),and the left ventricular end systolic diameter and left ventricular end diastolic diameter decreased significantly,after 3 and 6 months of treatm ent(P<0.05). However ,there was no significant difference in the velocity ratio of peak E to peak A ,pulmonary artery pressure ,right ventricular end diastolic diameter and the incidence of cardiogenic readmission events between 2 groups(P>0.05). CONCLUSIONS :For patients with AAMI complicated with acute cardiac insufficiency , compared with enalapril ,SVS can significantly improve the cardiac function (especially the left ventricular systolic function ), reduce the inflammatory reaction of cardiomyocytes ,protect cardiomyocytes ,so as to improve the short-term prognosis of patients.
