Objective To propose a family-centred health education program for family caregivers of Autistic children and investigate its clinical value.Methods Delphi method was used to establish a family-centred Autistic children care program for family caregivers looking after the Autistic children,which involved two rounds of expert consultation.The pre-and post-control method for different cases was employed in the study.Forty Autistic caregivers in our hospital from January 2022 to October 2022 were assigned to the control group and another 40 in our hospital from November 2022 to January 2023 were assigned to the observation group.The family caregivers of Autistic children in the control group received traditional care education,while those in the observation group was managed with the family-centred Autistic children health education program.The two groups were compared in terms of care burden,knowledge of health education,and evaluation of clinical symptom of Autistic children.Results The expert authority coefficient of the first round of expert consultation was 0.875 respectively and those in the second round was 0.900,respectively.The coefficient of variation of the coordination degree of each index was 0.04-0.20.Kendalls W scores of the two rounds were 0.794 and 0.786,respectively.A health education program for family-centred Autistic children caregiver was established to consist of three subjects:caregiver training,family-centred parental care and activation of positive emotions of autistic caregivers.Autism caregivers in both groups had completed the study.In comparison with the control group,the care burden of the observation group was significantly lower,the knowledge of health education was significantly higher,and the evaluation of children's clinical symptoms was better among the family caregivers of autistic children in the observation group(all P<0.05).Conclusions The family-centred autistic children care program for family caregivers is scientific and applicable.It is conducive to providing health education guidance for family caregivers of Autistic children,effectively reducing the care burden and enhancing the knowledge of health education.

Background: Classical swine fever (CSF) is a severe infectious disease of pigs that causes significant economic losses to the swine industry. Objectives: This study developed a solid-phase blocking enzyme-linked immunosorbent assay (spbELISA) method for the specific detection of antibodies against the CSF virus (CSFV) in porcine serum samples. Methods: A spbELISA method was developed based on the recombinant E2 expressed in Escherichia coli. The specificity of this established spbELISA method was evaluated using reference serum samples positive for antibodies against other common infectious diseases.The stability and sensitivity were evaluated using an accelerated thermostability test. Results: The spbELISA successfully detected the antibody levels in swine vaccinated with the C-strain of CSFV. In addition, the detection ability of spbELISA for CSFV antibodies was compared with that of other commercial ELISA kits and validated using an indirect immunofluorescence assay. The results suggested that the spbELISA provides an alternative, stable, and rapid serological detection method suitable for the large-scale screening of CSFV serum antibodies. Conclusions The spbELISA has practical applications in assessing the vaccination status of large pig herds.

In this study,thermosensitive and repairable molecularly imprinted solid-phase microextraction fibers were synthesized using spiramycin as template molecule,methacrylic acid and N-isopropylacrylamide as functional monomers,ethylene glycol dimethacrylate as crosslinking agent,and silanized quartz capillary as carrier. The prepared molecularly imprinted solid-phase microextraction fibers were characterized by scanning electron microscope and nitrogen adsorption/desorption,and various parameters affecting the extraction efficiency were optimized. Due to high selectivity and sensitivity of the fibers for macrolide antibiotics,the quantitative analysis of four macrolide antibiotics in food matrix,spiramycin,tilmicosin,tylosin,and josamycin,was peroformed in combination with high performance liquid chromatography. In the range of 0.5 to 50 μg/mL,the chromatographic peak area showed a good linear relationship with the concentration. The spike recoveries of the samples at three different addition levels were between 81.8% and 119.1%;the inter-day precisions were less than 13.8% (n=6),and the intra-day precisions were less than 15.5% (n=3).

A case with horizontal and vertical bone deficiency at the maxillary esthetic area is reported.A titanium disk was applied to maintain the space for guided bone regeneration,and ridge splitting and bone compressing technique were used to prepare the site.Finally,the restoration of implant tooth with favorable esthetic outcome was obtained.

Objective To investigate the internal quality control ( IQC ) on clinical chemistry , clinical immunology and clinical hematology in mutual recognition laboratories in medical institutions in Beijing.Methods By means of questionnaire survey and on -site investigation, fresh frozen serum and whole blood samples with assigned values by reference method were measured to investigate the status of IQC on clinical chemistry , clinical immunology and clinical hematology in 142 mutual recognition laboratories in medical institutions of Beijing,and results were analyzed.Results 142 copies of questionnaireson clinical chemistry, clinical immunology and clinical hematology were send out and 120, 97, and 101 laboratories returned the questionnaires respectively .The information feedback rate was 84.5%, 68.3% and 71.1%respectively .All the questionnaires were effective .Questionnaires survey results showed that more than 50%laboratories set up quality control goals and the most of the goals were probability for error detection ( Ped) 95%, probability for false rejection(Pfr)5%;About 70% laboratories usecd the same quality control plan for different tests ;The most frequently used quality control rules are 12s/13s/22s.On-site investigation showed that ,take the results of clinical chemistry for example , based on the desirable biological variation and WS/T 403 -2012 , most of the tests can't meet the quality control goalsunder the existing quality controlcondition.Conclusion Clinical laboratories should consider their actual situations , assess their own qualitylevels that they can reach , set reasonable quality standards for themselves , and make appropriateindividualized quality control plan.

Objective To investigate the expression pattern of transcription factor Olig 2 in cuprizone-induced mouse model of acute demyelination .Methods C57BL/6 mice were fed with 0.2%cuprizone to induce acute demyelina-tion.Immunofluorescence and qRT-PCR were used, and Olig2, MBP and GFAP were detected in the brain tissues of con-trol group and cuprizone-treated groups for 6 weeks and recovery for 2 weeks.Results Severe demyelination occurred in the corpus callosum following 6-weeks exposure to cuprizone , while remyelination was detected in the white matter after the mice were given diet without cuprizone .In the normal mice , Olig2 was expressed in a low level , while the experessions of Olig2 and GFAP were significantly increased , and Olig2 +/GFAP+cells were detected after demyelination .But the expres-sion of MBP was below the normal level with demyelination .After recovery for 2 weeks, the experession of Olig2 was lower, but the experessions of MBP and GFAP were increased .Conclusions Olig2 may play an important role in the glial differ-entiation from neural progenitor cells into active astrocytes , and in the glial scar formation .

Objective To assess the efficacy of radical transurethral electrovaporization for invasive bladder cancer. Methods Thirty-six patients with invasive bladder cancer from february 2008 to February 2010 were treated by transurethral electrovaporization resection of bladder tumor (TURBT). The operation procedure was based upon the principle of radical transurethral resection for bladder tumor. The tumor was resected to fatty layer outside the bladder wall. After operation Bacillus Calmette-Guerin (BCG) irrigation of bladder was given,all patients were followed up for 3 to 24 months. Results The recurrence occurred in 12 cases in 2 years,with a recurrence rate of 33. 3% (12/36). These recurrence cases were treated with TURBT again. Six cases dead in 2 years,with a mortality of 16. 7% (6/36). Conclusion TURBT is suitable for those who are older or weak,and not medically fit for radical cystectomy or those who refuse the open surgery,which can prolong the survival time and improve the quality of life.

Objective To investigate the differentially expressed genes in sporadic parathyroid adenomas using genechip and provide basis for further studying the mechanism and diagnosis of sporadic parathyroid adeno-mas. Methods Total RNA was extracted from normal parathyroid tissues and adenomas tissues. The mRNA was used to prepare probes. The mixed probes were hybridized to the cDNA microarray. After washing, the DNA chips were scanned by laser scanner. The acquired image was analyzed. Results Among the 47 000 target genes, 2302 genes were identified in sporadic parathyroid adenomas tissues that had at least two-fold changes compared to normal parathyroid tissues, and 1012 genes up-regulated and 1290 down-regulated were found in this study. Of 10 genes up-regulated and 27 down-regulated, the changes were over five-fold. The function of these changed genes was involved in transport, cell adhesion, signal transduetion, transcription, ion binding and so on. Conclusions Many parathyroid adenomas associated genes have been screened by high-throughout gene chip method, Which may help to identify the mechanism and diagnosis of sporadic parathyroid adenomas.
