Objective To investigate the effect of intensive lipid-lowering therapy on the imbalance between inflammatory and anti-inflammatory responses in patients with acute coronary syndrome (ACS).Methods Observed serum levels of hs-CRP and IL-IO in 82 patients with ACS, 17 patients with stable angina, and 22 controls. Forty-one patients with ACS were randomized to take either atorvastatin 10 mg/d (standard lipid-lowering therapy) or atorvastatin 40 mg/d (intensive lipid-lowering therapy) for one month in addition to their routine anti-anginal treatment. Serum levels of hs-CRP, blood lipids, IL-10 were investigat-ed.IL-10 was measured by ELISA. Results The level of hs-CRP in patients with ACS [(11.10 ± 14.30)mg/L] was higher than that in patients with stable angina [(2.47 ± 2.72) mg/L]and controls [(2.34 ± 4.22)mg/L] (P all < 0.05 ). The level of IL- 10 was lower in ACS patients [( 3.94 ± 1.91 ) ng/L] compared with those who had stable angina [(6.31 ± 4.26) ng/L] and controls [(7.76 ± 2.82) ng/L], Pan <0.05. The level of hs-CRP in patients with ACS was decreased and IL-10 was increased after one month treatment with atorvastatin (P < 0.05).The effect of atorvastatin 40 mg/d was more effective than that of atorvastatin 10 mg/d.Conclusions Patients with ACS have higher level of hs-CRP and lower level of IL-10 than those with sta-ble angina. This finding suggests that imbalance of inflammatory and anti-inflammatory responses is related with aggravation of atherosclerotic disease. Intensive lipid-lowering therapy is more effective than standard lipid-lowering therapy on ameliorating the imbalance.

Objective To investigate the dynamic changes of three types of anti-poliovirus neutralizing antibodies and anti-hepatitis A virus (HAV) IgG antibody in children who were immunized with inactivated enterovirus 71 (EV71) vaccine (human diploid cell).Methods Serum samples were collected from the subjects immunized with inactivated EV71 vaccine.Neutralizing antibodies against EV71 and poliovirus were detected by micro-cytopathic effect neutralization test.Enzyme linked immunosorbent assay (ELISA) was used to detect IgG antibody against HAV.Results The geometric mean titers (GMTs) of anti-EV71 neutralizing antibody increased to 4.85 following the first-dose injection of inactivated EV71 vaccine.A significant increase of GMTs (up to 64.37) could be observed 28 days after the second-dose vaccination.Meanwhile, results of the dynamic monitor showed that there were slight fluctuations in the neutralizing antibodies against three types of poliovirus on day 28 (28 days after the first-dose vaccination) compared with those on day 0 (before vaccination) (P<0.05);types Ⅰ and Ⅲ anti-poliovirus neutralizing antibodies on day 56 (28 days after the second-dose vaccination) remained slightly different from those on day 0 (P<0.05), but type Ⅱ anti-poliovirus neutralizing antibody on day 56 had restored to normal level (P>0.05).The level of anti-HAV IgG antibody was stable and no significant difference was found during the observation period (P>0.05).Conclusion This study shows that inactivated EV71 vaccine has no impact on anti-HAV IgG antibody in Children during the two-dose vaccination and in anti-EV71 antibody-producing period, but has slight influence on the anti-poliovirus antibodies.In general, changes in antibody profile do not affect the clinical efficacy of immune response.

Objective To explore the value of ultrasound in differential diagnosis of hepatic hilar cyst in neonates and infants. Methods The ultrasonographic characteristics of 93 children with hilar cysts under 6 months of age admitted to the General Surgery Department of Beijing Children′s Hospital. Affiliated to Capital Medical University from January 2014 to December 2018 were retrospectively analyzed. According to the surgical results,they were divided into two groups:cystic biliary atresia ( CBA) group and congenital choledochal cyst (CC) group,21 cases in the CBA group and 72 cases in the CC group. The size of cyst in hepatic portal area,the shape of gallbladder in empty stomach,the expansion of intrahepatic and extrahepatic bile ducts,the deposition of biliary sludge and the communication between cyst and intrahepatic bile duct were observed by ultrasound. Results The cyst volume of CBA group was 0. 4 ( 0. 1, 1. 3 ) cm3 , and that of CC group was 18. 3(5. 4,50. 3) cm3. The cyst volume of CBA group was significantly smaller than that of CC group (P<0. 01);19 cases had abnormal gallbladder morphology in CBA group and 4 cases in CC group (P<0. 01);1 case had biliary sludge in hilar cyst in CBA group and 51 cases had biliary sludge in cyst in CC group ( P <0. 01);no intrahepatic bile duct dilatation was observed in CBA group,and 54 cases had intrahepatic bile duct dilatation in CC group (P<0. 01);no cyst communicated with intrahepatic bile duct in CBA group,and all cysts communicated with intrahepatic bile duct in CC group (P <0. 01). Conclusion Gallbladder shape,cyst size,biliary sludge deposition,intrahepatic bile duct dilatation and the communication between cyst and intrahepatic bile duct can be used as sonographic features to differentiate CBA from CC.

Objective:To investigate the value of ultrasound in the diagnosis of secondary loss of response in children with Crohn′s disease at maintenance stage treated with Infliximab.Methods:From January 2017 to December 2021, 51 children with Crohn′s disease who received Infliximab treatment and clinical response in the Beijing Children′s Hospital Affiliated to Capital Medical University were retrospectively analyzed, and whether there was secondary loss of response during the maintenance period was observed. The ultrasound examination results at the 14th week of treatment were collected to understand the correlation between ultrasound examination of intestinal wall and peri-intestinal healing and secondary loss of response.Results:A total of 15 out of 51 patients (29.4%) experienced secondary loss of response during treatment follow-up up to 54 weeks. Compared to children with continuous response, children with secondary loss of response had a thicker intestinal wall at week 14 of treatment [5.0 (3.8, 6.0)mm compared to 3.0 (2.0, 4.0)mm, P<0.001], and a higher proportion of intestinal wall stratified structure disappearance [8/15 (53.33%) compared to 3/36 (8.33%), P<0.001]. When intestinal wall thickness>3.0 mm, the sensitivity was 0.955, and the specificity was 0.483. The sensitivity and specificity of clear diagnosis of secondary loss of response in intestinal wall stratification were 0.727 and 0.825, respectively. The sensitivity and specificity of combined diagnosis for secondary loss of response were 0.933 and 0.611, respectively. Conclusions:At the 14th week of treatment with Infliximab in children with Crohn′s disease, the thickness of intestinal wall measured by ultrasound being more than 3.0 mm and the disappearance of intestinal wall statified structure provide important information for the diagnosis of secondary loss of response.

Objective To evaluate the accuracy and clinical significance of the vesical imagingreporting and data system (Ⅵ-RADS) in predicting muscle-invasive bladder cancer (MIBC).Methods The data of 59 bladder cancer patients who underwent multiparametric magnetic resonance imaging and surgery between 2014 March and 2019 May were retrospectively analyzed,which includes 51 males and 8 females,aged 36-82 years old,with a median age of 62 years old.According to the scoring methods specified by Ⅵ-RADS,radiologists read and scored all mpMRIs including T2-weighted imaging (T2WI),diffusion-weighted imaging(DWI),and dynamic contrast enhancement MRI(DCE-MRI) of all the included patients.And then the Ⅵ-RADS were compared with pathological diagnosis.Proportions of MIBC in each score category were calculated,and ROC curve was plotted and the area under the curve (AUC) was estimated to assess the sensitivity and specificity of Ⅵ-RADS in diagnosing MIBC.Results The number of patients in Ⅵ-RADS score category 1 to 5 were 12,28,2,15 and 2,respectively.And there were 0,2 (7.4％),1 (50.0％),13 (81.3 ％),2 (100.0％) MIBC patients in each score category,respectively.When Ⅵ-RADS ≥3 was used to define MIBC,it came to the largest Youden's Index(0.7913),with an AUC of 0.924.And the sensitivity and specificity were 88.9％ and 90.2％,respectively.Conclusions Ⅵ-RADS has high accuracy in predicting MIBC,and it is worthy of application and verification in further clinical practice.The urologists should be highly alert to the existence of MIBC when Ⅵ-RADS ≥3.
