ObjectiveTo study X-ray and high resolution computed tomograghy(HRCT)features and tIleir relationship with pulmonary function test in pulmonary alveolar proteinosis(PAP).MethodsThe findings of X-ray and HRCT and the Resultsof pulmonary function tests in 19 patients with PAP were reviewed retrospectively.X-ray and HRCT scores were rated in the aspects of opacity density,extent,and severity.The relationship between the imaging scores and pulmonary function tests were determined.ResultsX-ray showed a symmetrical perihilar predominance appearance in patients with PAP.HRCT scan showed bilateral clear-defined pathchy areas of ground-glass opacity and interlobular septal thickening,a pattern commonly characterized as"crazy paving".Nineteen PAP respiratory function Resultswere:DLCO/Pred=(54.49±16.78)%,FEV1/FVC=(86.00±6.70)%.Chest radiographic extent score and severity score correlated with diffusing capacity(r=-0.661,P＜0.01,r=-0.475,P＜0.05).HRCT severity score was 16.47±5.26.Among all the HRCT scores,severity score correlated significantly with the presence of restrictive ventilatory defect and diffusing capacity defect(DLCO/Pred,r=-0.809,P＜0.01;FEV1/FVC,r=0.573,P＜0.05).ConclusionsIn patients with PAP,there Is close relationship between X-ray,HRCT findings and pulmonary function.HRCT correlates more closely with pulmonary function.

Objective To explore the relationship between traditional Chinese medicine (TCM) syndromes of state of evil domination and clinical and laboratory indicators of IgA nephropathy. Methods A prospective study was used to collect data on clinical and laboratory examination of IgA nephropathy in multi clinical centers. Patients’ TCM syndrome types were determined according to the national diagnostic criteria at the same time. Totally 266 patients with IgA nephropathy were included in the study to establish a database for analyzing the relationship between TCM syndrome of state of evil domination and clinical and laboratory indicators. Results In the relationship between syndromes of state of evil domination distribution and clinical subtypes, patients of wind-heat syndrome had more macroscopic hematuria;patients of phlegm-damp syndrome had more nephrotic syndrome;patients of damp-heat syndrome had more chronic nephritis type Ⅰ;patients of blood stasis syndrome had more chronic nephritis type Ⅱ. In the relationship between syndrome of state of evil domination distribution and clinical manifestation, the incidence of hypertension was higher in patients of blood stasis syndrome than in other three types. It was more serious for hematuresis in the patients of wind-heat syndrome. For patients of phlegm-damp syndrome, the incidence of heave proteinuria was highest. In the relationship between syndrome of state of evil domination distribution and laboratory examination, 24-hour urinary protein quantification was higher than in patients of wind-heat and damp-heat syndrome, but the level of blood albumin was lowest. For patients of blood stasis syndrome, serum creatinine level was significantly higher than in other three types;the level of eGFR was just the opposite. The levels of blood cholesterol and triglyceride in patients of phlegm-damp syndrome were higher than in other three types. The activated partial thromboplastin time (APTT) levels in patients of blood stasis and phlegm-damp syndrome were lower than in other patients, but the FIB level was the exact opposite of APTT. In the relationship between syndrome of state of evil domination distribution and the stages of chronic kidney disease (CKD), patients of wind-heat syndrome were more in the first stage of CKD;patients of blood stasis syndrome were more in the third stage of CKD. Conclusion There is relative correlation between TCM syndromes of state of evil domination and clinical and laboratory indicators in IgA nephropathy, which would provide some reference to narrow the gap in the information of the four methods of TCM with clinical and laboratory indicators to enhance accurate diagnosis of TCM syndrome.

Objective To evaluate the application value of MSCT in preoperative diagnosis and postoperative evaluation in children with cavernous transformation of the portal vein (CTPV).Methods 11 children diagnosed with CTPV by surgery were included in this study in our hospital.All patients underwent both plain and enhanced MSCT scans before surgery,and ultrasound or MSCT scan after surgery.Results In all 11 cases,preoperative CT showed different degrees of splenomegaly and the plain CT showed abnormal soft tissue mass in the hepatic hilar area.Enhanced CT showed stenosis or occlusion of portal vein trunk,earthworm-like blood vessels in the hilar region,and that the left and/or right branch of intrahepatic portal vein were replaced by multiple densely-distributed blood vessels (typeⅡ). Superior mesenteric-intrahepatic left portal shunt (Rex surgery)was performed in all 11 cases with successful results.All patients were followed up for 2-20 months after surgery.Imaging examinations showed anastomotic patency in 9 cases and stenosis in 2 cases.Conclusion MSCT findings of CTPV in children have certain characteristics.MSCT plays an important role in preoperative diagnosis and postoperative evaluation of CTPV in children.
