Objective: To investigate the clinical value of plasma brain natriuretic peptide (BNP) levels in predicting the severity of hand, foot and mouth disease (HFMD) in children with coxsackie virus A6 (CV-A6) infection. Methods: A total of 305 children with CV-A6 type HFMD admitted to Xi′an Children′s Hospital from January 2017 to December 2018 were divided into general group (200 cases) and severe group (105 cases) according to the severity of the disease.The receiver operating characteristic curve was used to calculate the value of plasma BNP levels to predict the severe CV-A6 HFMD.Multivariate logistic regression analysis was used to analyze the correlation between the related factors and the severity of CV-A6 HFMD. Results: Compared with the normal group, children in the severe group had statistically significant differences in WBC level, BNP level, neurological symptoms, circulatory disorders, and blood glucose levels(all P<0.05). The optimal cut-off value of the receiver operating characteristic curve for BNP level to predict severe HFMD was 294.85 ng/L.Multivariate logistic regression analysis found that WBC>15×10⁹/L, blood glucose> 8.3 mmol/L, and BNP>294.85 ng/L were related to the severity of CV-A6 HFMD(OR=2.275, P=0.013; OR=6.057, P=0.028; OR=1.008, P<0.001). Conclusion BNP>294.85 ng/L is closely related to the severity of CV-A6 HFMD and has predictive value.It is an early warning factor for the severity of CV-A6 HFMD.

Objective To assess the influence of active movement of the affected upper limb on the prognosis for patients after acute cerebral infarction.Methods From 2007 to 2008, 171 consecutive patients with acute cerebral infarction were registered prospectively in this study. Active movement of the hemiplegic upper limb was assessed on the 14th day after stroke onset. Ability in the activities of daily living was assessed using the Barthel index one year later.Results Finger flexion and extension on the 14th day after stroke onset correlated positively with Barthel index scores 1 year later. NIHSS scores at admission, the time interval from onset to admission and stroke history were significant predictors of the prognosis 1 year later.Conclusion Assessing the active movement of the hemiplegic upper limb on the 14th day after stroke has good predictive power for the prognosis of acute cerebral infarction patients.

OBJECTIVETo investigate the effect of noninvasive positive pressure ventilation( NIPPy) on the gene and protein expression of biquitin-proteasome of skeletal muscle in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).

METHODSSeven patients with AECOPD by NIPPV were used as the study group, meanwhile, 6 patients with AECOPD who refused NIPPV was the control group. The blood gas analysis, heart rate (HR) and mean arterial pressure (MBp) were monitored before and 14 days after treatment. A skeletal muscle biopsy was performed after 14 days of therapy. The mRNA expression of ribosomal protein S21 (RPS21), Ubiquitin, Ubiquitin combined with enzyme E2 (E2), Ubiquitin ligase E3 (E3) in skeletal muscle cell were measured by RT-PCR. The protein expression of mitochondrial aconitase (AC02), protease C3 (C3), ribosomal protein SLC16 (SLC16) were detected by Western blot.

RESULTSForteen days after treatment, the patients in NIPPV group got much better improvement in PaCO2, PaO2 and HR than that of the patients.in the control group (P < 0.05). The gene expression of RPS21,Ubiquitin, E2 and E3 in skeletal muscle cell on patients with NIPPV were obviously lower than that of the control group (P < 0.05, P < 0.01). Compared with that of the control group, the protein expression of C3 and AC2 increased significantly in the NIPPV group (P < 0.01). The protein expression of SLC16 was significantly lowered in the treated group (P < 0.01).

CONCLUSIONNIPPV can ameliorate the proteasome pathway and energy metabolic disorders in patients with AECOPD.

Danggui, Agelicae Sinensis Radix, is a widely used Chinese herb to enrich blood, but its quality cannot be effectively assessed by the known chemical markers such as ferulic acid, ligustilide, polysaccharides, etc. A new bioassay was therefore developed to quantify the Enrich-Blood Bioactivity (EBB) for the quality assessment of Danggui raw materials. Danggui sample was first extracted with ethanol and water, respectively. Then the ethanolic extract and water extract were mixed as a test sample to quantify the amount of EBB by mice experiment. The blood deficiency mode in mice was developed by intraperitoneal injecting cyclophospharmide and phenylhdrazine hydrochloride. The quantity of red blood cell was chosen as EBB marker. Cyclosporine A was chosen as a control substance. EBB in analytes was quantified by the amount reaction of parallel line analysis (3, 3') method. The results indicated that the reliability test for quantifying EBB was passed through and the measured value was valid. The analytes showed the significant EBB (P < 0.05). The correlation coefficient was 0.9984 (n=5) between the amount of cyclosporine A (0.035-0.56 g x kg(-1)) and the increased number of red blood cell. The relative standard deviation (RSY) on the amount of EBB was estimated to be 6.15% (n = 6) by six replicated tests, and the confidence limit rate was 26.68% (n = 6). Five Danggui samples, which were collected from different cultivation areas with various morphological characters, showed the variety of EBB in the range of 21.95-44.16 U x g(-1). It is concluded that the developed method is accurate to quantify the EBB of Danggui raw materials, and is therefore suitable to assess its quality.
