Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Purpose To explore the clinical value of quantitative assessment of renal perfusion using ultrasound contrast imaging for the auxiliary diagnosis of type 2 diabetic nephropathy.Materials and Methods This prospective study was conducted from May 2017 to December 2019 at the First Medical Center of Chinese PLA General Hospital.A total of 41 patients with type 2 diabetes and renal function abnormalities,who were scheduled for renal biopsy,underwent contrast-enhanced ultrasound.Differences in contrast imaging parameters,including time to peak in the renal cortex,peak enhancement,mean transit time local,and area under the curve between diabetic nephropathy and focal segmental glomerulosclerosis were compared,and the correlation between imaging parameters and pathological results was analyzed.Results Among 41 patients,30 cases were diagnosed as diabetic nephropathy,and 11 cases were diagnosed as focal segmental glomerulosclerosis.The peak enhancement and area under the curve in the diabetic nephropathy group were significantly lower than those in the focal segmental glomerulosclerosis group[peak enhancement:3 837.16(2 449.16,5 929.16)vs.8 508.00(4 334.88,21 201.00),Z=-2.766,P=0.006;area under the curve:0.14±0.05 vs.0.19±0.05,t=-3.135,P=0.003].In the diabetic nephropathy group,peak enhancement showed a negative correlation with the global glomerulosclerosis rate(r=-0.489,P=0.006).Conclusion Contrast-enhanced ultrasound can quantitatively evaluate renal perfusion and has certain clinical value in assisting the diagnosis of type 2 diabetic nephropathy.

Inflammation-to-tumor transition is one of the important mechanisms by which the cervical high-risk human papillomavirus(HR-HPV)infection develops into cervical cancer.Persistent cervical HR-HPV infection is an important cause of cervical cancer,and the focal uncontrolled inflammatory microenvironment caused by persistent cervical HR-HPV infection is the underlying mechanism of cervical cancer.The macroscopic and microscopic pathological process of inflammation-to-tumor transition is consistent with the pathogenesis evolution of damp-heat accumulation resulting into toxin in traditional Chinese medicine(TCM):the accumulation of damp-heat is the driving factor of inflammation-to-tumor transition,long-term retention of damp-heat leading to spleen deficiency and liver depression contributes to the characteristics of pathogenesis evolution,and long-term retention of damp-heat toxin causes the disorder of liver and spleen and then blood stasis accumulates in the cervical orifice,which eventually becomes cancer toxin.The process of inflammation-to-tumor transition caused by persistent cervical HR-HPV infection is due to the pathological factors of damp,heat,deficiency and toxin in TCM.Therefore,the regulation of inflammatory microenvironment caused by persistent cervical HR-HPV infection is the key approach to the prevention and treatment of cervical cancer.For the treatment of cervical cancer,methods of clearing heat and drying dampness,strengthening the spleen and soothing the liver are the key therapies.By intervention with the proper pathogen-eliminating methods and with simultaneous regulation of the interior and exterior,the process of inflammation-to-tumor transition can be interrupted.The exploration of inflammation-to-tumor transition caused by persistent cervical HR-HPV infection from the perspective of damp-heat accumulation resulting into toxin will provide thoughts for the prevention and treatment of cervical cancer with TCM and for Chinese medicine in intervening inflammation-to-tumor transition.

Lingnan LUO's Gynecological Diagnostics and Therapeutics is an intangible cultural heritage project of Guangdong Province and Guangzhou City,having both cultural and academic attributes.Lingnan LUO's Gynecological Diagnostics and Therapeutics developed from the Lingnan LUO's Gynecological Schools,with the genes of Lingnan culture and the imprint of Lingnan medicine.The intangible cultural heritage projects and academic schools of traditional Chinese medicine(TCM)have their own focuses in the cultural inheritance and academic communication.Intangible cultural heritage projects are established and evaluated by the cultural organizations,and their spread is mainly to the public in outreach communication;the academic schools are established by the administrative department of TCM,and their communication is usually in the professionals,occasionally by the outreach communication.The cultural inheritance and academic communication of TCM schools should focus on the in-depth exploration of TCM theory for enhancing the curative effect through the theoretical guidance for clinical practice.Moreover,the research team of academic schools needs to pay special attention to the inheritance of the discipline culture through the construction of workstations and other forms,aiming at the academic communication in the professionals,so that more practitioners will obtain the experience of the academic schools and will bring benefit to the public.Being different from the academic schools of TCM,the intangible cultural heritage projects of TCM have outstanding cultural attributes.The inheritors of intangible cultural heritage projects should not only be required to inherit the skills,but also be required to spread the discipline culture and skills to the public,thus to enable the public to understand the intangible cultural heritage projects of TCM and to prevent diseases and keep healthy with TCM spontaneously.The spread of intangible cultural heritage projects and academic schools of TCM should be based on the Chinese cultural self-confidence,and make full use of information and network technology,thus to introduce TCM culture at multiple levels and in multiple dimensions.

Objective:To determine the differential expressions of long non-coding RNA(lncRNA)and messenger RNA(mRNA)in normal and asthenospermia(AS)men and analyze their biological significance in AS.Methods:We isolated and ex-tracted total RNAs from 9 normal and 9 AS sperm samples,determined the expressions of RNAs in the sperm using the DNBSEQ se-quencing platform,and analyzed their relevant functions by gene ontology enrichment(GO)and Kyoto encyclopedia of genes and ge-nomes pathway(KEGG)analyses.Results:An average of 10.64G data was generated per group,with 282 185 RNAs detected,in-cluding 107 009 lncRNAs.Among the total number of lncRNAs,15 157 were differentially expressed,2 190 upregulated and 12 967 downregulated;and among the 19 514 mRNAs,13 736 were differentially expressed,4 995 upregulated and 8 741 downregulated.Differentially expressed genes were enriched mainly in the sperm cell membrane and the pathways related to the ion channel functions,sperm development and fertilization.Conclusion:Differentially expressed lncRNAs and mRNAs can be identified by sequencing a-nalysis of AS and normal sperm.Regulation of sperm function through membrane ion channels may contribute to the development of AS,which provides a molecular basis for further research on AS.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

OBJECTIVE: To investigate the effect of Cyr61 on imatinib (IM) resistance in chronic myeloid leukemia (CML) and its mechanism. METHODS: Cyr61 level in cell culture supernatant was determined by enzyme-linked immunosorbent assay. The expression of Cyr61 and Bcl-xL were measured by real-time PCR and Western blot. Cell apoptosis was analyzed using an Annexin V-APC Kit. Expression of signal pathways related proteins was determined by Western blot. RESULTS: The level of Cyr61 obviously increased in K562G cells (IM resistance to CML cell line K562). Down-regulating the expression of Cyr61 decreased the resistance of K562G cells to IM and promoted IM induced apoptosis. In CML mouse model, down-regulating the expression of Cyr61 could increase the sensitivity of K562G cells to IM. The mechanism studies showed that Cyr61 mediated IM resistance in CML cells was related to the regulation of ERK1/2 pathways and apoptosis related molecule Bcl-xL by Cyr61. CONCLUSION Cyr61 plays an important role in promoting IM resistance of CML cells. Targeting Cyr61 or its related effectors pathways may be one of the ways to overcome IM resistance of CML cells.
