Objective To investigate the effects of cognitive interventions (CIs) in the context of communi- ty based rehabilitation (CBR) on cognitive deficits (CDs) in stroke patients.Methods Ninety-two stoke patients with CDs were randomly divided into a CI group and a control group.All patients were treated with conventional CBR.In addition,the patients in the CI group were also treated with special intervention therapy.The patients in both groups were assessed with the neurological and cognitive status examination (NCSE) for cognitive functioning, the FCA for motor function and the BI for their ability in the activities of daily living.Results The NCSE,FCA and BI scores in the cognitive intervention group after treatment were significantly higher than those before treatment and also significantly higher than those in the control group after treatment.Conclusion CIs can not only improve CDs,but also enhance recovery of motor function and ADL.

OBJECTIVE: To study the clinical features of children with adenovirus pneumonia and hemophagocytic lymphohistiocytosis (HLH). METHODS: A retrospective analysis was performed on the mediacal data of 7 children with adenovirus pneumonia and HLH from March to September, 2019. RESULTS: The age of these children ranged from 11 months to 5 years, and among these children, 5 were aged <2 years and 5 were boys. None of these children had underlying diseases. All children were hospitalized due to persistent high fever and cough, and the peak temperature of fever was 39°C to 41°C. With disease progression, 7 children developed hepatomegaly and 6 developed splenomegaly. Routine blood test results showed reductions in two or three lineages of blood cells, with increases in serum ferritin (SF), C-reactive protein (CRP), procalcitonin (PCT), and lactate dehydrogenase (LDH). Phagocytosis of blood cells was observed in 6 children. Radiological examination of lungs showed pneumonia changes. All 7 children were diagnosed with human adenovirus type 7 infection based on pathogenic metagenome detection. No abnormality was found by HLH gene detection and the children were diagnosed with secondary HLH. All children received intravenous immunoglobulin. Among these children, 4 received dexamethasone and etoposide chemotherapy, 3 received dexamethasone alone, and 4 received plasma exchange. Of the 7 children, 2 died and 5 were recovered. Compared with those who survived, the children who died had significantly greater reductions in the three lineages of blood cells and significantly greater increases in serum levels of CRP, PCT, SF, and LDH. CONCLUSIONS The children with adenovirus pneumonia and HLH have main clinical features of persistent high fever, progressive reductions in two or three lineages of peripheral blood cells, and involvement of other organ systems, including hepatosplenomegaly. Significant increases in serum levels of CRP, PCT, SF, and LDH may suggest a poor prognosis.

To construct plasmid of recombinant protein candidate vaccine of respiratory syncytial virus, express it in E. coli, and to investigate its immunogenicity and protective efficacy. A CD8+ T cell epitope from respiratory syncytial virus (RSV) M2 protein F/M2:81 - 95 and the G:125-225 (G1) gene fragments from RSV-G protein containing B cell epitopes were amplified by PCR method and then inserted into the prokaryotic expression vector pET-DsbA after bonding to a linker. The fusion protein DsbA-G1-Linker-F/M2:81-95 (D-G1LF/M2) was expressed successfully in E. coli BL21 (DE3). The product was proved to be RSV-specific by Western-blot. After purified by affinity chromatography on Ni+ Sepharose and renatured by gradient dialysis. D-G1LF/M2 was used to immune BALB/c mice. D-G1LF/M2 induced high anti-D-G1LF/M2 IgG, anti-RSV IgG and neutralizing antibody titers in serum and lung of BALB/c mice, and elicied RSV-specific CTL responses. The IgG subclass distribution revealed that IgG1/IgG2a ratio was 2.66. Viral titration indicated that D-G1LF/M2 could protect BALB/c mice against RSV challenge in lung.

In order to make clear the packing mechanism of the BmNPV polyhedra, a polyhedrin gene negative recombinant baculovirus, vBmBac(polh-)-5B-EGFP, expressing EGFP was constructed, and used to infect BmN cells jointly with wild-type BmNPV. Fluorescent microscopic observation demonstrated that EGFP and polyhedrin were expressed simultaneously, and the EGFP expression and polyhedra formation occurred in most of the jointly infected cells. Analysis of the purified polyhedra from jointly infected BmN cells showed that the foreign proteins were present in the polyhedra. The results indicated that BmNPV polyhedrin could incorporate proteins other than viral proteins into the polyhedra. It implies that a nonspecific recognition mechanism exists in the embedment of BmNPV polyhedra.

OBJECTIVETo observe and compare the effects of 17beta-estradiol (EST) on the phasic and tonic contractile activities of the uterine smooth muscles of SD rats in vitro.

METHODSDifferent concentrations of 17beta-estradiol were added into the perfusion muscular sockets containing uterine smooth muscles of SD rats, and the activities of muscle contraction were recorded at the same time.

RESULTS17beta-estradiol had obvious depression effects on spontaneous rhythmic contraction of the uterine smooth muscles in a concentration-dependent manner, it could considerably decrease muscular tension, the mean amplitudes and frequencies of contractile waves (P < 0.01); it could also suppress the uterine contraction stimulated by KCl, CaCl2 or prostaglandin F2alpha (PGF2alpha). Based on the contraction of uterine smooth muscle stimulated by KCl, IC50 was 7.278 micromol/L and pD2 was -0.862 when calculated by linear regression method. 17beta-estradiol could also inhibit the maximal CaC12 contraction of uterine smooth muscle in the Ca2+ free Krebs solution, which the ECQ was 1.422 x 10(-3) mol/L, pD2 was 2.847 (control), but the E50 was 3.028 x 10(-3) mol/L, p2 was 2.519 (added with EST) when calculated by linear regression method.

CONCLUSIONThe depression effects of 17beta-estradiol on the spontaneous rhythmic contraction and activated contraction of the uterine smooth muscles of SD rats could be mediated through the blockage of C2+ influx through potential-dependent Ca2+ channels of plasma membrane.

OBJECTIVETo investigate the expression profiles of serum Golgi protein-73 (GP73) in liver cirrhosis and primary hepatic carcinoma (PHC) and determine its clinical value for differential diagnosis.

METHODSSerum protein expressions of GP73 and alpha-fetoprotein (AFP) were detected by enzyme-linked immunosorbent assay and chemiluminescence assay, respectively, in patients with PHC (n=80), liver cirrhosis (n=65), and healthy controls (n=50). Inter-group changes were assessed by Kruskal-Wallis test, and significance of these differences was assessed by Mann-Whitney test. A receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency and determine the cut-off values for GP73 and AFP. Sensitivity and specificity were compared by the Chi-squared test. Correlation between serum GP73 expression and clinical parameters was determined by Spearman's rank correlation analysis.

RESULTSThe PHC group showed significantly higher serum GP73 (282.0 mug/L) than the liver cirrhosis group (211.8 mug/L) and control group (58.3 mug/L) (H = 93.30, P less than 0.01). For differential diagnosis of PHC and liver cirrhosis, the cut-off value was 318.1 mug/L for GP73 and 13.4 mug/L for AFP. Sensitivity of GP73 was lower than AFP (45% (36/80) vs. 65% (52/80); X2 = 8.02, P less than 0.05). Specificity of GP73 was lower than AFP but no significance was found (83.1% (54/65) vs. 87.7% (57/65); X2=0.27, P more than 0.05). The areas under the ROC curves were not significantly different between GP73 and AFP (0.65 (95% confidence interval (CI): 0.54~0.72) vs. 0.75 (95% CI: 0.67~0.83); Z = 1.88, P more than 0.05). The area under the ROC curves increased but not significantly (0.80 (95% CI: 0.73~0.88) vs. 0.75 (95% CI: 0.67~0.83); Z=2.61, P more than 0.05). Serum GP73 was correlated with liver cirrhosis (r=0.27), vascular invasion (r=0.29), and TNM staging (r=0.27) (all P less than 0.05), but not with sex (r=0.13), age (r=0.10), enhanced AFP (> 13.4 mug/L; r=0.03), tumor size (r=0.18), or distant metastasis (r=0.04), all P less than 0.05.

CONCLUSIONSerum GP73 and AFP have comparable diagnostic efficiency, but the sensitivity of AFP is superior for differential diagnosis of liver cirrhosis and primary hepatic carcinoma. Elevated serum GP73 may be correlated with liver tumor load and aggressiveness.

OBJECTIVETo detect potential mutations for probands from families affected with Duchenne/Becker muscular dystrophy (DMD/BMD), and to carry out prenatal diagnosis through identification of female carriers.

METHODSA total of 43 DMD/BMD families were recruited. Multiplex PCR was used to analyze 18 exons within hotspots for DMD gene deletions. Multiplex ligation-dependent probe amplification (MLPA) was used to detect potential deletions and duplications of DMD gene for 43 patients and 36 females from 32 families. Prenatal diagnosis was performed for 27 families.

RESULTSDeletional mutations were detected in 26 patients with multiplex PCR. In addition, MLPA has detected 3 deletions and 6 duplicational mutations, and the ranges of mutations were all determined. Among 36 female members, 18 were determined as carriers of deletional mutations, 10 were excluded as mutation carriers. The status of remaining 8 could not be determined. For prenatal diagnosis, 3 out of 18 male fetuses were diagnosed as patients and 1 female fetus was identified as carrier.

CONCLUSIONMLPA is an accurate and reliable method for detecting deletional/duplicational mutations of DMD gene as well as for prenatal diagnosis and detection of female carriers.
