Objective:To examine the occurrence of seizures and perioperative risk factors in children after obtaining cardiopulmonary bypass (CPB).Methods:Electroencephalograph (EEG) and cerebral oxygen saturation (ScO 2) were monitored in 87 patients (aged 3 days-110 months, with the median at 4.4 months) and they were admitted to the Cardiac Intensive Care Unit (CICU) from May 2018 to April 2019, with 77 patients for 72 h after CPB and 10 cases with clinical seizures after CICU discharge for 8-180 h. Clinical data were recorded every 4 hours, including blood pressure, central venous pressure (CVP), temperature, arterial blood gases, lactate, doses of Dopamine, Milrinone, and Adrenalin, and daily C-reaction protein (CRP) and N-terminal pro-brain natriuretic peptide(NT-proBNP). Demographic data, the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery(STAT) mortality classification and clinical outcomes (duration of mechanical ventilation, CICU and hospital stay, and death) were recorded. Results:Seizures occurred in 24 patients (27.6%) within 48 h after CPB.EEG seizures appeared in 7 patients, both EEG and clinical seizures in 7 patients, and clinical seizures in 10 patients.Three patients developed epilepsy.There were 2 hospital deaths and both had EEG seizures.Patients with seizures had higher STAT categories, longer operative time and worse clinical outcomes (all P<0.05). Univariate regression revealed that the occurrence of seizures was positively related to adrenalin, temperature, lactate level (all P<0.01), blood pressure, CVP (all P<0.05) and CRP ( P<0.1), and negatively correlated with arterial carbon dioxide tension[ pa(CO 2)], ScO 2 and dose of Milrinone (all P<0.05). In multivariate regression, only dose of Adrenalin ( P<0.001) and lactate level ( P<0.01) remained significant. Conclusions:The incidence of seizures was high in children after CPB.Numerous perioperative factors that were related to seizures were identified.The most significant risk factors were higher dose of adrenaline and lactate level.Studies on neurological injury after CPB are urgently needed in China in order to reduce brain injury and improve neurodevelopmental outcomes.

Objectives It was constructed that the replication defective adenoviral vectors carried the short hairpin sequences of mouse SCP2.And we will make a further study of mechanism between SCP2 gene and cholesterol stone in gallbladder.Methods The short hairpin sequences of mouse SCP2 were cloned by two-step PCR,and connected together with the plasmid pDC312.The Admax Adenoviral Vector System was used to generate the replication defective adenoviral vectors,which were purified by CsCl method.The processes of TCID50 were applied to detect the titers of the adenoviral vectors.Furthermore,Protein levels of SCP2 were determined by Western blot analysis,and the levels of SCP2、CYP7A1、HMGCR mRNA from the hepa1-6 cell of mouse were measured by the usage of RT-PCR.Results SCP2mRNA and SCP2 protein were down-regulated by the replication defective adenoviral vectors carried the SCP2-shRNA.With the decreasing SCP2mRNA,the levels of HMGCRmRNA were down-regulated at same the time,while CYP7A1mRNA were up-regulated.Conclusions The replication defective adenoviral vectors carried SCP2-shRNA were constructed successfully.The lower levels of SCP2 could affect the activities of HMG-CoA reductase and CYP7-a enzyme,which caused the variations of cholesterol metabolism and then decreased the formation of cholesterol stone.

Objective To evaluate X-ray,CT and MRI findings of soft tissue infections in AIDS. Methods Three cases of soft tissue infections with AIDS were retrospectively analyzed by comparing the imaging findings with pathological results.All patients were performed MRI,X-ray was in 1 case,CT was in 1 case.Results Cellulitis was in 1 case:MRI showed extended thickening of subcutaneous tissues, ill-defined hypointense areas on T_1WI and hyperintensity on T_2WI,and reticular pattern on GRE. Necrotizing fasciitis was in 1 case:MRI showed obvious thickening of subcutaneous tissues and deep fasciae, abnormally increased signal intensity on T_1 and T_2WI.Fluid collections were within muscles and muscles interval on fat-suppressed T2 WI.Tuberculosis was in 1 case:CT demonstrated multiple low density areas in the subcutaneous tissues and clear peripheral rim enhancement.MRI appeared hypointense on T_1WI and hyperintensity on T_2WI,and peripheral rim enhancement following gadolinium injection.Conclusion Infections of soft tissue are common complication in patients with AIDS,radiology is important in early diagnosis and treatment planning in this population.

Objective To investigate the discrepancy of aldosterone synthesis process and potential regulation abnormality between aldosterone-producing adenoma(APA) and normal adrenal(NA) with microarray. Methods cRNA probes labelled with biotin were prepared from mRNA of APAs(APA group,n=10) or NAs(control group,n=7).The probes were hybridized with oligonucleotide microarray of target gene expression profile.Expression levels were read from the fluorescent intensity scanned.The difference of gene expression profile was analyzed by computer software.Differentially expressed genes were verified by real-time RT-PCR. Results Compared with control group,97 genes were up-regulated and 168 genes were down-regulated in APA group.In the genes related to steroid hormone synthesis,only CYP11B2 was significantly up-regulated.In the physiologic regulators of aldosterone synthesis,CYB5A,CYP17A1,DUSP1 and HMGCR were down-regulated,while RENBP and NR1H2 were up-regulated.As a key enzyme in the biosynthesis of cortisol,the expression of CYP17A1 gene was inhibited. Conclusion Among the aldosterone synthesis related enzyme and corresponding regulatory genes in APA,CYP11B2 may be a key synthetase,and the suppressed physiologic regulators of aldosterone synthesis may indicate the existence of neoplastic modulation.

OBJECTIVEIt aims to study potential genotoxicity of almond skins.

METHODSA bacterial reverse mutation assay was performed on S. typhimurium strains TA97, TA98, TA100, TA102, and TA1535 in the absence or presence of S-9 mixture at a dose range of 312.5 to 5 000 μg/plate. A micronucleus test and a mammalian bone marrow chromosome aberration tests were performed in Swiss Albino (CD-1) mice at doses of 625, 1 250, and 2 500 mg/kg bw used.

RESULTSAlmond skins exerted no mutagenic activity in various bacterial strains of Salmonella typhimurium in either the absence or the presence of metabolic activation at all doses tested. Various doses of almond skins did not affect the proportions of immature to total erythrocytes, the number of micronuclei in the immature erythrocytes, or the number of structural and numerical chromosomal aberrations of Swiss albino mice.

CONCLUSIONAlmond skins are not genotoxic under the conditions of the in vitro bacterial reverse mutation assay and two in vivo tests - micronucleus test and mammalian bone marrow chromosome aberration test, which supports the safety of almond skins for dietary consumption.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.
