Objective To comment the severity of severe hand,foot and mouth disease(HFMD)by pediatric risk of mortality score(PRISM),and assess the performance of PRISM in predicting mortality or complication probability in HFMD.Methods Four hundred and twenty-four severe HFMD pediatric patients were recruited in the study from 1th Jan 2010 to 31th June 2013.Information on the outcome and the varia-bles required to calculate PRISM score were collected.The logistic regression model developed in the learning sample was evaluated in the test sample by calculating the area under the receiver operating characteristic (ROC)curve to assess discrimination pneumorrhagia and death.Calibration across deciles of risk was evalua-ted using the Hosmer-Lemeshow goodness-of-fit χ2 test.Results The area under the ROC curve were 0.87 (95%CI 0.80~0.94 )for PRISM in predicting pneumorrhagia probability.The area under the ROC curve were 0.87(95%CI 0.80~0.95)for PRISM in predicting mortality probability.The PRISM in observed and expected pneumorrhagia did not demonstrate good calibration at ten mortality risk intervals (χ2 =36.66, P<0.001 ).The PRISM in observed and expected mortality did not demonstrate good calibration at ten mortali-ty risk intervals(χ2 =41.11,P<0.001).Conclusion The PRISM score is demonstrated good discrimination of pneumorrhagia and death in HFMD pediatric patients,but the performance of calibration is not good.

Objective:To investigate the correlation between serum procalcitonin (PCT) level and intracranial atherosclerotic burden (ICASB) in patients with ischemic stroke.Methods:From January 2019 to December 2020, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, Jiangsu Provincial Second Chinese Medicine Hospital were enrolled. Chemiluminescence immunoassay was used to detect serum PCT levels, and ICASB was evaluated based on the results of cranial magnetic resonance angiography. Univariate analysis was used to determine the baseline data among the different ICASB score groups. Then the independent correlation between serum PCT level and ICASB was determined by the ordinal logistic regression analysis. At the same time, the correlation between serum PCT level and ICASB was determined by the linear regression analysis. Results:A total of 291 patients with acute ischemic stroke were enrolled, including 161 male (55.3%), aged 64.5±8.4 years; median serum PCT level was 0.053 μg/L. According to the ICASB score, the patients were divided into 0 group ( n=155, 53.3%), 1-3 group ( n=95, 32.6%) and >3 group ( n=41, 14.1%). Univariate analysis showed that the age, serum homocysteine and PCT level, as well as the proportion of diabetes were significantly higher in the higher ICASB score group, while the proportion of the patients with atrial fibrillation was significantly lower (all P<0.05). Ordinal multivariable logistic regression analysis showed that higher serum PCT level was an independent factor for higher ICASB score (the 4 th quartile vs. the 1 st quartile: odds ratio, 2.015, 95% confidence interval 1.052-3.927; P=0.043). Multiple linear regression analysis showed that the serum PCT level was positively correlated with the ICASB score ( r=0.253, P=0.001). Conclusion:The serum PCT level is correlated with ICASB.

Objective The abnormal ankle-brachial index ( ABI) is associated with the incidence of cardiocerebral vascular diseases, but little is known about its relationship with cerebral microbleeds (CMB).This study aimed to investigate the correlation be-tween ABI≤0.9 and different distribution patterns of CMB . Methods We enrolled 187 patients with acute lacunar infarction , inclu-ding 115 non-CMB cases and 72 CMB cases (20 strictly lobar, 24 strictly deep, and 28 lobar and deep).We analyzed the differences between the two groups and the association of abnormal ABI with the occurrence and distribution of CMB by logistic regression analysis . Results ABI≤0.9 was found in 57 (30.5%) of the patients, with a significantly higher incidence rate in the CMB group than in the non-CMB group (43.1%vs 22.6%, P=0.003).The level of ABI was negatively correlated with the number of CMBs (r=-0.211, P=0.006).Multivariate logistic regression analysis after adjusted for confounders indicated that ABI ≤0.9 was significantly associated with the presence of CMB (OR=2.363;95%CI:1.181-4.729), deep CMB (OR=3.434;95%CI:1.283-9.187), and lobar and deep CMB ( OR=2.837;95%CI:1.098-7.333) in patients with ischemic cerebrovascular disease . Conclusion Decreased ABI is a risk factor of CMB, particularly deep CMB, in patients with ischemic stroke.

Objective To investigate the expression of Dysadherin and analyze its role in renal clear cell carcinoma (RCCC).Methods RT-PCR and immunohistochemical were used to detect the expression of Dysadherin in 60 cases of fresh RCCC and 60 adjacent normal renal tissues(male 35,female 25; age 37-78,median age 61; ＞7 cm 24,≤7 cm 36; Ⅰ/Ⅱ 39,Ⅲ/Ⅳ 21).Results Dysadherin mRNA expression in RCCC tissues (2.0043±0.2890) was higher than that in adjacent normal renal tissues (0.8461 ±0.2479) (t =6.8020,P ＜ 0.05).Dysadherin expression was associated with nuclear grade.The expression of Dysadherin in nucleus grade Ⅲ and Ⅳ tumors were significantly higher than that in nucleus grade Ⅰ and Ⅱ tumors [the mRNA expression were 4.6224±0.3194,2.7780±0.2288,the positive rates of protein were 64.1％ (25/39),95.2 ％ (20/21) (t =6.5750,x2 =5.495,P ＜ 0.05)].There was no association between the expression of Dysadherin with sex (t =1.0530,x2 =0.023),age(t =0.0511,x2 =0.089) and tumor size (t =1.0330,x2 =0.370) (P ＞ 0.05).Conclusion In RCCC,Dysadherin expression is positively associated with tumor aggressiveness based on grading.It seems that Dysadherin may be a valuable prognostic marker in RCCC.

Objective To investigate the risk factors for reduced renal function in patients with ischemic stroke.Methods The medical records of patients with ischemic stroke were analyzed retrospectively.They were divided into normal renal function group and reduced renalfunction group.Reduced renal function was defined as estimated glomerular filtration rate (eGFR) ＜60 ml/(min·1.73 m2).Multivariate logistic regression analysis was used to identify the risk factors for reduced renal function in patients with ischemic stroke.Results A total of 805 patients with ischemic stroke were enrolled in the study.8.8％ of patients had a reduced renal function.There was no significant differences in the proportion of patients with mild and moderate neurological deficit between the reduced renal function group and the normal renal function group (all P ＞ 0.05),however,the proportion of patients with severe neurological deficit was significantly higher than that in the normal renal function group (8.4％vs.2.6％,x2 =5.573,P =0.017).The proportion of small artery occlusion in the reduced renal function group was sigaificantly higher than that in the normal renal function group (66.2％ vs.46.5％,x2 =9.962,P =0.002),and the proportion of large artery atherosclerosis was significantly lower than that in the normal renal function group (19.7％ vs.43.5％,x2 =15.045,P =0.000).Multivariate logistic regression analysis indicated that old age (odds ratio [ OR] 3.301,95％ confidence interval [ CI],1.575 to 6.918; P=0.002) was the most important independent risk factor for reduced renal function,then was female (OR,2.291,95％ CI 1.355to 3.872; P=0.002) and hyperlipidemia (OR,2.527,95％ CI 1.095 to 5.831; P=0.030).Conclusions Reduced renal function in patients with ischemic stroke is strongly associated with old age,female,and hyperlipidemia.

OBJECTIVEThis study investigated the role and mechanism of calcineurin (CaN)-nuclear factor of activated T cells (NFAT) pathway in the myoblast apoptosis induced by cyclic tensile strain.

METHODSMyoblasts were cultured using an in vitro-mechanical stimulation model and imposed with tension for different hours with a multi-channel cell stress loading system. Cyclosporine (CsA) was used as CaN inhibitor to clarify the role of CaN in the apoptosis induced by cyclic stress. Hochest 33258 staining and flow cytometry detection were performed to detect the apoptotic cells. Real-time polymerase chain reaction was conducted to detect the mRNA expression of CaN and NFAT. Protein levels of NFAT3 were evaluated by Western blot.

RESULTSThe apoptosis rate increased with the extension of loading time. The mRNA expression of the CaN subunits, CnA and CnB, and the protein levels of NFAT3 also increased. When the myoblasts were incubated with CsA, the apoptosis rate decreased, the mRNA expression of CnA and NFAT3 significantly decreased, and the NFAT3 protein expression levels became significantly lower than those of the groups without CsA.

CONCLUSIONContinuous cyclic tensile stress can induce myoblast apoptosis. The CaN-NFAT signaling pathway may be involved in the cyclic stretch-induced apoptosis of myoblasts.

OBJECTIVETo report on prenatal diagnosis and follow up of two patients with paternal uniparental disomy of chromosome 6 (pUPD6).

METHODSFetal cells were subjected to in situ culturing and G-banded chromosomal analysis. DNA samples of the fetuses and their parents were also analyzed with single nucleotide polymorphism microarray (SNP array).

RESULTSBoth fetuses had a normal male karyotype. SNP array analysis showed both have carried pUPD6.

CONCLUSIONpUPD6 can lead to transient neonatal diabetes mellitus type 1. Homozygous status of recessive mutations, disorder of gene imprinting, and its influence on placental function are the main factors to be considered during prenatal diagnosis and genetic counseling for pUPD6.
