Objective:To systematically evaluate the current status and methodological quality of guideline and consensus in ovarian stimulation for in vitro fertilization (IVF), and to provide reference for the development of future guidelines and research. Methods:A systematic search was conducted in databases including PubMed, Embase, CNKI, Wanfang, Sinomed and relevant guideline websites from inceptions to October 2024. Data were extracted from the literature that met the inclusion criteria, and methodological quality was assessed using the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) tool. Descriptive analysis was performed with results presented in visual data charts.Results:A total of 23 studies were included, with 8 guidelines and 15 consensus. Totally 21 (91.3%) studies focused on the selection of ovarian stimulation protocols, with the majority concentrating on protocols for patients undergoing IVF treatment for the first cycle, and 12 (52.2%) studies focused on the selection of gonadotropin starting dosage. In terms of methodology, the average standardized scores in the 6 assessment domains of the AGREE Ⅱ tool were as follows: scope and purpose (85.1%), stakeholder involvement (66.6%), rigour of development (36.5%), clarity of presentation (70.1%), applicability (36.4%), and editorial independence (46.2%).Conclusion:Current recommendations in ovarian stimulation for IVF exhibit inconsistencies, and the methodological quality varies, which partially hinders the translation of evidence into clinical practice. Future research should further focus on the selection of ovarian stimulation protocols and gonadotropin starting dosage, promoting the update and refinement of guidelines and consensus to guide the precise treatment of ovarian stimulation.

Objective:To explore the feasibility of using a simplified multiple sleep latency test (MSLT) for the diagnosis of narcolepsy type 1.Methods:Data from 158 patients with narcolepsy type 1 and 58 patients with non-type 1 narcolepsy who underwent overnight video-polysomnography (V-PSG) and MSLT in the Sleep Center, Department of Neurology, Xijing Hospital, Air Force Military Medical University from March 2019 to April 2024 were retrospectively collected. By reducing the number of naps in the MSLT, the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT was evaluated using the receiver operating characteristic (ROC) curve. The DeLong test was used to compare whether there was a statistically significant difference between the simplified MSLT and the standard 5-nap MSLT. Cohen′s Kappa statistical analysis was performed to compare the diagnostic consistency between the simplified MSLT and the standard 5-nap MSLT.Results:The age of the 216 patients who were ultimately enrolled was 17 (13, 30) years, including 152 male patients (70.4%). The Cohen′s Kappa between the simplified 3-nap MSLT and the standard 5-nap MSLT was 0.875, which was 0.903 between the simplified 4-nap MSLT and the standard 5-nap MSLT (Bonferroni-corrected, both P0.001), indicating high and statistically significant agreement for both simplified protocols with the standard test. However, the DeLong test revealed that the area under the curve of the standard 5-nap MSLT (0.900, 95% CI 0.863-0.938) differed significantly from that of the simplified 3-nap MSLT (0.860, 95% CI 0.817-0.904; P0.05), whereas no significant difference was observed between the standard 5-nap MSLT and the simplified 4-nap MSLT (0.876, 95% CI 0.834-0.918; P0.05). Consequently, performing only the first 4 naps was sufficient for diagnosing narcolepsy type 1. Conclusion:The simplified 4-nap MSLT, specifically the first to fourth naps, may be used for the diagnosis of narcolepsy type 1.

AIM:To identify transcriptional differences between the ocular surface ectoderm(OSE)and surface ectoderm(SE)using RNA-seq, and elucidate the OSE transcriptome landscape and the regulatory networks involved in its development.METHODS:OSE and SE cells were differentiated from human embryonic stem(hES)cells. Differentially expressed genes(DEGs)between OSE and SE were analyzed using RNA-seq. Based on the DEGs, we performed gene ontology(GO)analysis, Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis, and protein-protein interaction(PPI)network analysis. Transcription factors(TFs)and hub genes were screened. Subsequently, TF-gene and TF-miRNA regulatory networks were constructed using the NetworkAnalyst platform.RESULTS:A total of 4 182 DEGs were detected between OSE and SE cells, with 2 771 up-regulated and 1 411 down-regulated genes in OSE cells. GO-BP analysis revealed that up-regulated genes in OSE were enriched in the regulation of ion transmembrane transport, axon development, and modulation of chemical synaptic transmission. Down-regulated genes were primarily involved in nuclear division, chromosome segregation, and regulation of cell cycle phase transition. KEGG analysis indicated that up-regulated genes in OSE cells were enriched in signaling pathways such as cocaine addiction, axon guidance, and amphetamine addiction, while down-regulated genes were enriched in proteoglycans in cancer, ECM-receptor interaction, protein digestion and absorption, and cytokine-cytokine receptor interaction. Additionally, compared with SE, 204 TFs(including FOS, EGR1, POU5F1, SOX2, and PAX6)were up-regulated, and 80 TFs(including HAND2, HOXB6, HOXB5, HOXA5, and HOXB8)were down-regulated in OSE cells. Furthermore, we identified 6 up-regulated and 9 down-regulated hub genes in OSE cells, and constructed TF-gene and TF-miRNA regulatory networks based on these hub genes.CONCLUSIONS:The transcriptome characteristics of OSE and SE cells were elucidated through RNA-seq analysis. These findings may provide a novel insight for studies on the development and in vitro directed induction of OSE and corneal epithelial cells.

Objective:To summarize the clinical and electrophysiological characteristics of epilepsy patients with fixation-off sensitivity (FOS).Methods:Using "fixation-off sensitivity" and "epilepsy" as search terms, data were retrieved from the Electroencephalogram Monitoring Center Database of Xijing Hospital, Air Force Military Medical University. Information was collected on epilepsy patients with FOS who were seen at the Xijing Hospital Electroencephalogram Monitoring Center from March 2019 to May 2023. A retrospective analysis of video electroencephalograms and clinical information was conducted, along with follow-up. Single factor analysis and multi-factor Logistic regression analysis were used to analyze the risk factors affecting the prognosis of the patients.Results:A total of 78 patients met the inclusion criteria, including 43 females and 35 males; the age at first epilepsy onset was 12.00 (8.00, 15.25) years. Among these 78 patients, 46 were diagnosed with genetic generalized epilepsy, 11 with self-limited focal epilepy, 9 with familial cortical myoclonic tremor with epilepsy, 7 with developmental and epileptic encephalopathy, 3 with symptomatic epilepsy, and 2 with progressive myoclonic epilepsy. The fixation-off induction trial most commonly triggered seizures in epilepsy with eyelid myoclonia (EEM) patients, with eyelid myoclonia being the most common type of seizure. Twenty-five epilepsy patients with FOS showed a positive photoparoxysmal response, of whom 6 experienced photo-convulsive response. Sixty-eight patients completed follow-up with comprehensive clinical data. At the last follow-up, 45 patients had been free from tonic-clonic seizures for at least one year. A history of febrile seizures ( OR=20.559, 95% CI 2.179-193.997, P=0.008) and cognitive decline ( OR=3.752, 95% CI 1.118-12.588, P=0.032) were identified as risk factors for poor prognosis in epilepsy patients with FOS. The age of first epilepsy onset, the number of anti-seizure medications, and the intermittent photo stimulation trial results had no correlation with prognosis. Conclusions:FOS is more common in female epilepsy patients and can be observed in both generalized and focal epilepsy syndromes. EEM patients are prone to seizures during fixation-off induction trial, and the most common type of seizures is eyelid myoclonus seizure. Patients with epilepsy with FOS who have a history of febrile seizures and cognitive impairment tend to have poor prognosis.

Epilepsy with eyelid myoclonia (EEM), also known as Jeavons syndrome, is a type of genetic generalized epilepsy officially recognized by the International League Against Epilepsy. The clinical characteristics of EEM include eyelid myoclonia, eye closure sensitivity, and photosensitivity, typically manifesting in childhood with a higher prevalence in female patients. The prognosis of EEM is poor, and seizures are difficult to fully control even with standardized drug treatment. The electroencephalogram of EEM often shows fast interictal multiple spike-wave complexes, which can be induced by eye closure or photic stimulation. Functional magnetic resonance imaging and other studies have found that EEM is associated with brain network abnormalities, particularly the key role of the central medial thalamic nucleus in the regulation of cortical excitability. Genetic research has found that EEM may be related to variations in genes such as CHD2, SYNGAP1, NEXMIF, RORB, and GABRA1.

Objective:To understand the current rehabilitation status and existing problems of patients with degenerative scoliosis after surgery, and analyze the needs of continuous health education for patients.Methods:A total of 15 patients with degenerative scoliosis undergoing surgical treatment in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from December 2021 to June 2022 were selected by the convenient sampling method. The semi-structured interview was used to understand the patient's feelings on the operation effect, experience on the postoperative life impact, thoughts on rehabilitation exercise, self-cognition of home status and future development planning. Based on the rooted theory, Colaizzi 7-step analysis was applied to extract the topic.Results:The four themes related to the continuous health education needs of patients with degenerative scoliosis after surgery were summarized, which were unacceptable movement limitation of lower back or lower extremity, blind area of continuous rehabilitation exercise, lack of knowledge of self-management of spinal disease after surgery and need for social and psychological support.Conclusions:Patients with degenerative scoliosis lack of postoperative rehabilitation knowledge and skills, and the need for health education is strong. Medical staff can meet the patients' transitional care needs by educating them to adapt to the current situation, providing personalized rehabilitation goals, guiding patients in managing risk factors that affect their own rehabilitation and improving social and family support systems, thereby promoting rapid recovery of patients.

Objective:To discuss the molecular association pattern of Shenling Baizhu Powder for type 2 diabetes (T2DM) and ulcerative colitis through network pharmacology method based on the theory of "treating different diseases with same method" in TCM.Methods:The TCMSP and ETCM Chinese medicine chemical composition databases were used to obtain the chemical composition and predict the targets of Shenling Baizhu Powder. The OMIM, GeneCards, DrugBank and TTD disease databases were used to obtain the disease targets of T2DM and ulcerative colitis. The intersection targets of chemical composition of Shenling Baizhu Powder, T2DM and ulcerative colitis were obtained by Bioinformatics platform. Cytoscape 3.8.2 software was used to map the "Chinese materia medica-component-target" network and "effective component- intersection target" network. The GO enrichment analysis and KEGG pathway analysis of the intersection targets were performed with the STRING platform. The intersection target protein-protein interaction network was constructed by STRING database, and core targets were obtained using the CytoNCA plugin of Cytoscape 3.8.2 software. AutodockTools software was applied to validate the molecular docking between the core chemical components and the core targets of Shenling Baizhu Powder.Results:Totally 176 chemical components of Shenling Baizhu Powder, 226 corresponding targets, 11 478 T2DM targets, 4 857 Ulcerative targets of ulcerative colitis, and 162 intersection targets of medicinal chemistry components and diseases were obtained. 1 789 related biological processes, 163 molecular functions, 92 cell constituents, and 192 signaling pathways were obtained by GO enrichment analysis and KEGG pathway analysis. The signaling pathways were mainly about AGE-RAGE, TNF, IL-17,MAPK, PI3K-Akt signaling pathways, etc. The core components of Shenling Baizhu Powder were mainly sitosterol, luteolin, kaempferol, naringenin, beta-carotene, etc. The core targets were EGFR, ALB, IL1B, CASP3, ESR1, VEGFA, PTGS2, TNF, IL6, MYC, AKT 1, JUN, TP53, etc. The core chemical components had tight correlation with the core targets by the molecular docking.Conclusions:By acting on core targets such as TNF, IL1B, IL6, AKT1, VRGFA, PTGS2, MYC, JUN, TP53, and regulating IL-17 signaling pathway, TNF signaling pathway, MAPK signaling pathway, AGE-RAGE signaling pathway, etc., Shenling Baizhu Powder improves tissue inflammation damage, mucosal barrier damage, immune regulation imbalance, intestinal flora dysbiosis, insulin resistance, apoptosis, oxidative stress and other biological processes. Therefore Shenling Baizhu Powder can treat T2DM and ulcerative colitis with the same method.

Background: Classical swine fever virus (CSFV), the causative agent of classical swine fever (CFS), is a highly contagious disease that poses a serious threat to Chinese pig populations. Objectives: Many provinces of China, such as Shandong, Henan, Hebei, Heilongjiang, and Liaoning provinces, have reported epidemics of CSFV, while the references to the epidemic of CSFV in Yunnan province are rare. This study examined the epidemic characteristics of the CSFV in Yunnan province. Methods: In this study, 326 tissue samples were collected from different regions in Yunnan province from 2015 to 2021. A reverse transcription-polymerase chain reaction (RT-PCR), sequences analysis, and phylogenetic analysis were performed for the pathogenic detection and analysis of these 326 clinical specimens. Results: Approximately 3.37% (11/326) of specimens tested positive for the CSFV by RTPCR, which is lower than that of other regions of China. Sequence analysis of the partial E2 sequences of eleven CSFV strains showed that they shared 89.0–100.0% nucleotide (nt) and 95.0–100.0% amino acid (aa) homology, respectively. Phylogenetic analysis showed that these novel isolates belonged to the subgenotypes 2.1c and 2.1d, with subgenotype 2.1c being predominant. Conclusions The CSFV was sporadic in China’s Yunnan province from 2015 to 2021. Both 2.1c and 2.1d subgenotypes were found in this region, but 2.1c was dominant.
