Objective To study the pattern of cerebral gray matter and white matter volume changes among smokers with differ-ent level of nicotine dependence (addition)using voxel-based morphometry (VBM).Methods The current case-control study recrui-ted 53 healthy male smokers and 53 healthy non-smokers from outpatients of our hospital during January 2013 to May 2014.Personal information (including for example age,sex and addition dependence of subjects)was collected using a questionnaire.3D-T1 images of whole brain structure were collected and were analyzed using DARTEL toolbox of SPM8.Smokers were divided into mild to mod-erate nicotine dependence group (n=23)and severe nicotine dependence group (n=30)based on Fagerstr?m Test for Nicotine De-pendence (FTND)score.Independent sample t-test analyses were performed to compare the volumes of gray matter and white mat-ter between smokers with different levels of nicotine dependence and non-smokers.Results Compared with non-smokers,gray and white matter volumes of smokers were smaller in multiple brain areas,mainly in the middle occipital gyrus,posterior cingulate,cer-ebellum anterior lobe,precuneus,caudate body and insula,which however,had larger number and scope of focal areas with gray and white matter atrophy in the mild to moderate nicotine dependence group than that in the severe nicotine dependence group.Conclusion Smokers with mild to moderate nicotine dependence have more pronounced gray and white matter atrophy than that smokers with severe nicotine dependence have.

Lysozyme, pepsin, ovalbumin, hemoglobin andγ-globumin were chosen as templates to investigate the imprinting capability of amphoteric polyacrylamide cryogels. Prepolymerizing solutions contained acrylic acid and allyl amine, as well as acrylamide and N,N'-methylenebisacrylamide as the functional monomers. As a result there were both acidic and basic functional groups in the polymers, facilitating effective interactions with likewise amphoteric proteins. The proteins differ greatly and cover wide scopes of molecular weights and isoelectric points. Regardless of the values of the molecular weights and isoelectric points, all the templates gave higher retentions on the MIP tubes than on the NIP tube. The MIP of lysozyme indicated the highest imprinting factor of 7. 0, and that of γ-globumin showed the lowest, 2. 0. The values of other proteins were intervenient. Conclusively the amphoteric polyacrylamide cryogels were suitable imprinting materials for various proteins, and could potentially be used for protein recognition, purification, and depletion.

Objective:To analyze the causal relationship between gut microbiota and gestational diabetes,and to clarify its mechanism.Methods:Two-sample Mendelian randomization(MR)analysis was conducted by using summary data from genome-wide association study(GWAS)for gut microbiota and gestational diabetes.The GWAS data of gut microbiota were obtained from a GWAS study from the MiBioGen consortium;the GWAS data on gestational diabetes were sourced from the FinnGen consortium's publicly available R8 dataset;inverse variance weighted(IVW)method was used as the primary method to detect the causal association between the gut microbiota and the gestational diabetes.Sensitivity analysis was performed by Weighted Median and MR Egger methods;heterogeneity and pleiotropy were detected by Cochran's Q,MR-PRESSO,Egger intercept tests and Leave-One-Out analysis;multivariable MR was used to adjust for the effect of body mass index(BMI);reverse MR was used to explore the presence of reverse causal associations;Gene Ontology(GO)fuctional and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling enrichment analyses were used to explore the potential pathways through which gut microbiota may have impact on gestational diabetes.Results:Four gut microbes were found to be causally associated with gestational diabetes:the genus Methanobrevibacter and the phylum Euryarchaeota displayed negative causal relationships with the risk of gestational diabetes,while the genus Olsenella and genus Lachnoclostridium exhibited positive causal associations.No significant heterogeneity or horizontal pleiotropy was detected in the analysis.The reverse MR analysis did not reveal any causal relationship.After adjusting for BMI,the multivariable MR analysis results showed there were the causal associations between the genus Olsenella and the phylum Euryarchaeota with the risk of gestational diabetes.The GO fuctional and KEGG signaling pathway enrichment analyses results showed that axon development,axon production,insulin secretion and other pathways were significantly enriched.Conclusion:There are causal associations between four gut microbes and gestational diabetes.Among them,the significant correlations with gestational diabetes are still observed in phylum Euryarchaeota and genus Olsenella after adjusting for BMI.

Objective To investigate the mechanism of C-C motif chemokine ligand 5(CCL5)modulation by extracellular matrix stiffness in non-small cell lung cancer(NSCLC)and to determine the effect of CCL5 on the immunotherapy response of NSCLC.Methods The correlation between extracellular matrix stiffness and CCL5 expression in NSCLC was analyzed with the TCGA database.Polyacrylamide hydrogels with different stiffness were designed according to the extracellular matrix stiffness of NSCLC,and H1299 cells responding to the mechanical loading of hydrogel matrix stiffness were subjected to transcriptome sequencing.High matrix stiffness was verified to promote the expression of CCL5 by using sequence.Results High extracellular matrix stiffness upregulated CCL5 expression,and interferon-γ mediated signaling pathway might be involved in the process.NSCLC patients with high CCL5 expression had a greater abundance of cytotoxic T-cells in tumor tissue and reacted favorably to anti-programmed cell death protein 1 treatment.Conclusion Increased extracellular matrix stiffness promotes CCL5 synthesis,and CCL5 enhances immunotherapy responsiveness in NSCLC by increasing cytotoxic T cell infiltration in tumor tissue.

Objective To investigate the correlation between 23 metals and metalloids elements in the urine and thyroid function indicators in the blood of traffic police. Methods A cross-sectional study was performed to assess the effects of 23 metals and metalloids elements in the urine on blood thyroid function indicators in 166 traffic policemen (122 field staff and 44 internal staff) in Wuhan, Hubei Province. Each subject received an occupational health examination. Results After multiple corrections for false detection rates, in the polymetallic model, the levels of urinary manganese and urinary uranium were positively correlated with the levels of thyroid peroxidase antibody (TPOAb) in the blood (β = 66.57, 95% CI 2.92-130.22, P = 0.040 and β = 62.43, 95% CI 14.37-110.49, P = 0.011), and the level of urinary uranium was positively correlated with thyroid stimulating hormone (TSH) levels in the blood (β = 6.20, 95% CI 2.68-9.72 , P = 0.001). Urinary uranium level was negatively correlated with free thyroxine level in the blood (FT4) (β = -2.03, 95 % CI (-3.67 )- (-0.39), P = 0.015), and urinary lead level was negatively correlated with blood TSH level (β = -4.59, 95% CI (-8.67) - (-0.51), P = 0.027). Conclusion Manganese exposure is related to the increase of TPOAb level in blood, uranium exposure is related to the increase of TPOAb and TSH levels and the decrease of FT4 level in blood, and lead exposure is related to the decrease of TSH level in blood, suggesting that more attention should be paid to the effects of heavy metals on the thyroid of traffic police.

Bevacizumab, an anti-VEGF monoclonal antibody, has significantly improved the clinical outcomes of patients with advanced non-squamous NSCLC (ns-NSCLC). However, the safety and efficacy of bevacizumab for elderly patients with advanced NSCLC require further investigation. Thus, 59 patients were included in the present retrospective study, 22 patients in the bevacizumab plus pemetrexed and platinum (B + PP) group, and 37 patients in the pemetrexed and platinum (PP) group. For the entire cohort of patients, the median OS was 33.3 months, and the 1-year and 2-year overall survival rates were 88.5% and 67.8%, respectively. The median OS and 1-year and 2-year OS rates were 20.5 months, 70.3% and 0%, respectively, in the B + PP group and 33.4 months, 97.0% and 89.4%, respectively, in the PP group (P < 0.001). The incidence of grade ⩾ 3 adverse events was higher in the B + PP group than in the PP group (27.3% vs. 10.8%, respectively; P = 0.204). Univariate and multivariate analyses suggested that the receipt of ⩾ 5 cycles of first-line chemotherapy was an independent favorable prognostic factor for OS, whereas the addition of bevacizumab was an unfavorable prognostic factor. With increased toxicities, the addition of bevacizumab to PP does not improve the overall survival of elderly patients with advanced ns-NSCLC.

In order to screen African swine fever virus (ASFV) diagnostic antigen with the best enzyme linked immunosorbent assay (ELISA) reactivity. By establishing the ELISA method, the diagnostic antigen of ASFV p30 protein expressed by baculovirus-insect cell expression system as reference, we explored the antigenic properties and diagnostic potential of ASFV p35 protein expressed by prokaryotic expression system as a diagnostic antigen. The results of Western blotting and immunofluorescence show that the molecular weight of the recombinant p35 protein and p30 protein obtained was 40 kDa and 30 kDa, respectively, and these two proteins had good immuno-reactivity with ASFV positive serum. Recombinant p30 and p35 proteins were used as diagnostic antigens to establish ELISA, and the sensitivity and repeatability of these methods were tested. The results show that although the detection sensitivity of the p30-ELISA established in this study was higher than that of the p35-ELISA, the sensitivity of p35-ELISA was 95.8%, and variations in intra- and inter-assay repeatability of the two methods were less than 10%. The coincidence rate between the p35-ELISA and the imported kit was 97.2%. Results show that p35-ELISA was sensitive and stable, and could detect specific antibodies against ASFV.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.
