OBJECTIVE To evaluate the impact of the specialized centralized procurement policy for insulin on daily cost and affordability of insulin， and provide data support for the enhancement of relevant policies. METHODS In this research， the insulin purchasing data were obtained from provincial centralized procurement platforms in provinces before and after the specialized centralized procurement of insulin （October-December 2021 and October-December 2022）， and the cost variations of insulin before and after the centralized procurement were analyzed by the defined daily dose cost （DDDc） of various types of insulins. The changes in the affordability of various types of insulins before and after the specialized centralized procurement were evaluated， using the percentage of annual expenditure on various types of insulins relative to annual per capita disposable income （i.e. the proportion of annual expenditure） as an indicator. RESULTS After the specialized centralized procurement， DDDc of various types of insulins decreased by 20.7%-71.8%， with an average reduction of 45.7%. Moreover， the reduction in DDDc for third-generation insulin exceeded that for second-generation insulin. The reduction in the proportion of annual expenditure on insulin ranged from 24.3% to 73.4%， with an average decrease of 48.5%. Premixed insulin analogs experienced the greatest reduction （73.4%）. Following the specialized centralized procurement， DDDc of insulin decreased in all provinces. Except for Guangxi （10.2%）， the average proportion of annual expenditure on insulin in the remaining provinces dropped to below 10%. CONCLUSIONS The specialized centralized procurement policy for insulin has significantly reduced insulin costs and improved affordability， thereby alleviating the economic pressure on patients with diabetes. There are notable cost disparities among provinces and among insulin categories， which require attention.

Objective To analyze the short-term clinical outcomes of emergency conversion to surgery during transcatheter aortic valve replacement (TAVR). Methods Clinical data of patients who underwent emergency surgical conversion from TAVR in the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University, from 2018 to 2023 were collected. Postoperative follow-up results at 1 month were recorded. Results A total of 253 patients underwent TAVR, of whom 11 (4.3%) required emergency conversion to surgery. Among these 11 patients, 7 were male and 4 were female, with a mean age of (69.55±5.01) years. The primary cause for emergency surgical conversion was valve stent displacement (63.6%), followed by left ventricular perforation/rupture (18.2%) and significant perivalvular regurgitation persisting after a second valve implantation (18.2%). One (9.1%) patient died intraoperatively. Among the 10 surviving patients, postoperative complications included pulmonary infection in 8 patients, severe pneumonia in 7, pleural effusion in 3, liver dysfunction in 8, renal dysfunction in 3, upper gastrointestinal bleeding in 5, cerebrovascular complications in 1, atrial fibrillation in 1, ventricular premature contractions in 1, atrioventricular block in 1, and complete left bundle branch block in 3. At 1-month postoperative follow-up, one additional patient died, yielding a 30-day mortality rate of 18.2% after TAVR emergency surgical conversion. The quality of life improved significantly compared to preoperative status in 9 (81.8%) patients, and no patients were readmitted for cardiovascular diseases. Conclusion The incidence of emergency conversion to surgery during TAVR is low, but the rates of surgical complications and 30-day postoperative mortality are high. Nevertheless, when severe complications occur during TAVR, emergency conversion to surgery can still yield satisfactory short-term clinical outcomes for a majority of these patients.

Depressive disorders are common mental illnesses characterized by significant and persistent low mood, with features such as high prevalence, high disability rate, and high suicide rate. The microbiota-gut-brain axis may be one of the potential mechanisms underlying depressive disorders. Gut microbiota metabolites, as important mediators of MGBA signaling, play roles in depressive disorders through multiple pathways. These include short-chain fatty acids, which can regulate the transmission of the vagus nerve, inflammatory responses, and 5-hydroxytryptamine synthesis; secondary bile acids, which can activate farnesoid X receptor and Takeda G protein-compled receptor 5; and choline, which can regulate DNA methylation and trimethylamine N-oxide production. This article reviews the literature on the potential mechanisms of action of gut microbiota metabolites, such as short-chain fatty acids, secondary bile acids, and choline, in depressive disorders. The literature was retrieved from CNKI, PubMed, and Web of Science databases from 2010 to 2025. It aims to provide a theoretical basis for the prevention and treatment of depressive disorders.

Loss-of-function variants in CSDE1 have been strongly linked to neuropsychiatric disorders, yet the precise role of CSDE1 in neurogenesis remains elusive. In this study, we demonstrate that knockout of Csde1 during cortical development in mice results in impaired neural progenitor proliferation, leading to abnormal cortical lamination and embryonic lethality. Transcriptomic analysis revealed that Csde1 upregulates the transcription of genes involved in the cell cycle network. Applying a dual thymidine-labelling approach, we further revealed prolonged cell cycle durations of neuronal progenitors in Csde1-knockout mice, with a notable extension of the G1 phase. Intersection with CLIP-seq data demonstrated that Csde1 binds to the 3' untranslated region (UTR) of mRNA transcripts encoding cell cycle genes. Particularly, we uncovered that Csde1 directly binds to the 3' UTR of mRNA transcripts encoding Cdk6, a pivotal gene in regulating the transition from the G1 to S phases of the cell cycle, thereby maintaining its stability. Collectively, this study elucidates Csde1 as a novel regulator of Cdk6, sheds new light on its critical roles in orchestrating brain development, and underscores how mutations in Csde1 may contribute to the pathogenesis of neuropsychiatric disorders.

The"season-visceral-related"theory originated from Huangdi Neijing,and its content contains the"holism of five viscera"and"correspondence between nature and humans"in the theoretical system of traditional Chinese medicine(TCM).Recently,the prevalence of post-stroke cognitive impairment(PSCI)has gradually increased with the increasing incidence of stroke.TCM believes that PSCI is located in the brain,however,the causative factors such as phlegm,depression,deficiency,and stasis are caused by the lesions of the five zang viscera.Therefore,PSCI can not be treated with the brain alone.Based on the"season-visceral-related"theory,this article discusses the etiology,pathogenesis,and treatment ideas for PSCI from the four seasons and five zang viscera.Xiaoyao Pill was selected as a treatment for patients with qi imbalance in spring to disperse stagnated liver qi to relieve qi stagnation.Tianwang Buxin Dan was selected as a treatment for patients with blood loss and spirit injury in the summer to nourish the blood and calm the heart and brain.Kaixin Powder was selected as a treatment for patients with spleen deficiency and phlegm blockage in late summer to strengthen the spleen,awaken the mind,and remove stasis.Wenfei Jiangzhuo Decoction was selected as a treatment for patients with qi deficiency and spirit departure in autumn to nourish the lungs,reduce turbidity,and nourish the mind.Dihuang Yinzi was selected as a treatment for patients with marrow reduction and internal toxin in winter to expel phlegm and fill the mind.Treating PSCI using the"season-visceral-related"theory reflects the overall concept of TCM and the hypothesis of syndrome differentiation and treatment and provides novel method for treating PSCI.

Background::Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized immune-mediated disorder that can affect almost any organ in the human body. IgG4-RD can be categorized into proliferative and fibrotic subtypes based on patients’ clinicopathological characteristics. This study aimed to compare the clinical manifestations, laboratory findings, and treatment outcomes of IgG4-RD among different subtypes.Methods::We prospectively enrolled 622 patients with newly diagnosed IgG4-RD at Peking Union Medical College Hospital from March 2011 to August 2021. The patients were divided into three groups according to their clinicopathological characteristics: proliferative, fibrotic, and mixed subtypes. We compared demographic features, clinical manifestations, organ involvement, laboratory tests, and treatment agents across three subtypes. We then assessed the differences in treatment outcomes among 448 patients receiving glucocorticoids alone or in combination with immunosuppressants. Moreover, risk factors of relapse were revealed by applying the univariate and multivariate Cox regression analysis.Results::We classified the 622 patients into three groups consisting of 470 proliferative patients, 55 fibrotic patients, and 97 mixed patients, respectively. We found that gender distribution, age, disease duration, and frequency of allergy history were significantly different among subgroups. In terms of organ involvement, submandibular and lacrimal glands were frequently involved in the proliferative subtype, while retroperitoneum was the most commonly involved site in both fibrotic subtype and mixed subtype. The comparison of laboratory tests revealed that eosinophils ( P = 0.010), total IgE ( P = 0.006), high-sensitivity C-reactive protein ( P <0.001), erythrocyte sedimentation rate ( P <0.001), complement C4 ( P <0.001), IgG ( P = 0.001), IgG1 (P <0.001), IgG4 (P <0.001), and IgA ( P <0.001), at baseline were significantly different among three subtypes. Compared with proliferative and mixed subtypes, the fibrotic subtype showed the lowest rate of relapse (log-rank P = 0.014). Conclusions::Our study revealed the differences in demographic characteristics, clinical manifestations, organ involvement, laboratory tests, treatment agents, and outcomes across proliferative, fibrotic, and mixed subtypes in the retrospective cohort study. Given significant differences in relapse-free survival among the three subtypes, treatment regimens, and follow-up frequency should be considered separately according to different subtypes.Trial Registration::ClinicalTrials. gov, NCT01670695.

Objective To investigate the frequency of therapy-oriented oral radiation in Nanping, China and its distribution, and to provide a basis for the rational application of therapy-oriented oral radiation and the effective allocation of resources in Nanping. Methods A questionnaire was designed to investigate the frequency of therapy-oriented oral radiation in all oral radiation diagnosis and treatment institutions in Nanping. Results In 2021, there were 54 oral radiation diagnosis and treatment institutions and 79 oral radiation machines in Nanping. The total frequency of therapy-oriented oral radiation was 61593 visits and the radiation frequency was 19.54 visits per thousand patients. The average annual frequency of medical institutions at all levels was 721.87 to 3713.25 visits per institution; the male-to-female composition ratio of frequency of therapy-oriented oral radiation in December 2021 was 50.5%:49.5%. The proportion of radiation frequency of different devices was as follows: 38.7% (intraoral dental film), 46.5% (oral panorama), 10.3% (oral computed tomography [CT]), and 4.5% (cranial photography). The proportion of radiation frequency in patients of different ages was as follows: 17.1% (0−15 years), 48.2% (15−40 years), and 34.7% (over 40 years). The frequency of therapy-oriented oral radiation grew by 77.43%, 35.18%, and 8.16% every two years from 2015 to 2021, respectively. Conclusion The frequency level of therapy-oriented oral radiation in Nanping is at the level of Class II health care. The distribution of therapy-oriented oral radiation is highly unbalanced and is related to the level of economic development. Private healthcare institutions are growing rapidly, and public healthcare institutions of grade two and above occupy the main healthcare resources. The oral panorama accounts for the most, cranial photography accounts for the least, and oral CT is the fastest-growing portion. Therapy-oriented oral radiation is predominantly performed in the young and middle-aged populations, regardless of sex. Except for intraoral dental films, the general trend is upward.

Objective:To investigate and analyze the status quo and risk factors of swallowing function and safe eating behavior in elderly type 2 diabetes patients with frailty, so as to provide a reference for clinical early identification and early prevention.Methods:From July 2021 to December 2022, 295 patients with type 2 diabetes accompanied with frailty were selected from the Endocrinology Department of Beijing Friendship Hospital Affiliated to Capital Medical University by convenience sampling. Patients were surveyed using the Tilburg Frailty Indicator (TFI) and the Eating Assessment Tool-10. Single factor analysis and Logistic regression analysis were used to explore the influencing factors of swallowing function and safe eating behavior in elderly type 2 diabetes patients with frailty.Results:A total of 295 questionnaires were distributed, and 291 valid questionnaires were collected, with an effective response rate of 98.64%. There were 94 cases in the group with abnormal swallowing function and safe eating behavior, and 197 cases in the group with normal swallowing function and safe eating behavior. There were statistical differences in age, body mass index, duration of diabetes, TFI score, education level, and number of chronic diseases between the two groups ( P<0.05). Logistic regression analysis showed that the duration of diabetes ( OR=1.047, P=0.024), TFI score ( OR=1.147, P=0.009), and the number of chronic diseases ( OR=1.282, P=0.035) were the influencing factors of swallowing function and safe eating behavior in elderly type 2 diabetes patients with frailty. Conclusions:Abnormal swallowing function and safe eating behavior are common in elderly type 2 diabetes patients with frailty, and the duration of diabetes, frailty and chronic comorbidity are independent risk factors.

Objective:To explore the genetic etiology of a fetus with Coffin-Siris syndrome2 (CSS2).Methods:A fetus with abnormal ultrasound findings detected at Luoyang Maternal and Child Health Care Hospital in July 2023 was selected as the study subject. Clinical data were analyzed retrospectively. Whole exome sequencing was carried out on fetal tissue and parental peripheral blood samples, and candidate variant was verified by Sanger sequencing and pathogenicity analysis. This study was approved by Medical Ethics Committee of the Luoyang Maternal and Child Health Hospital (Ethics No. LYFY-YCCZ-2023011).Results:Color Doppler ultrasound at 16 + gestational weeks revealed bilateral ventriculomegaly and cerebellar hypoplasia in the fetus. Trio-WES found that the fetus has harbored a heterozygous c. 553C>T (p.Gln185Ter) variant of the ARID1A gene, which was verified by Sanger sequencing to have a de novo origin. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 553C>T (p.Gln185Ter) variant of the ARID1A gene was classified as pathogenic (PVS1+ PS2+ PM2_Supporting). Conclusion:The fetus was diagnosed with CSS type 2, and the heterozygous c. 553C>T (p.Gln185Ter) variant of the ARID1A gene probably underlay its brain malformations.
