Objective:
To examine the associations between three adipokines (omentin-1, nesfatin-1 and apelin) and diabetic retinopathy (DR) among patients with type 2 diabetes mellitus (T2DM), so as to provide the basis for the prevention and control of DR.
Methods:
The T2DM patients hospitalized in Lishui TCM Hospital from August 2021 to May 2023 were selected and divided into three groups: no diabetic retinopathy (NDR) group, non-proliferative diabetic retinopathy (NPDR) group, and proliferative diabetic retinopathy (PDR) group based on fundus fluorescein angiography. Data on gender, age, and course of T2DM were collected through questionnaires, and serum omentin-1, nesfatin-1, apelin, and related blood biochemical indicators were measured. The associations of omentin-1, nesfatin-1 and apelin with DR were analyzed using a multinomial logistic regression model.
Results:
A total of 150 T2DM patients were enrolled, including 58 cases in the NDR group, 60 cases in the NPDR group, and 32 cases in the PDR group, with males accounting for 60.34%, 45.00% and 68.75%, respectively. The mean ages were (54.79±14.40), (57.03±12.20) and (57.72±10.70) years, respectively. The median (interquartile range) courses of T2DM were 7.00 (7.75), 10.00 (8.00) and 10.00 (5.00) years, respectively. Compared with the NDR group, the NPDR group had lower levels of omentin-1 and nesfatin-1 and higher level of apelin, while the PDR group had higher level of omentin-1 and lower level of apelin (all P<0.05). Compared with the NPDR group, the PDR group had higher levels of omentin-1 and nesfatin-1 and lower level of apelin (all P<0.05). Multinomial logistic regression analysis showed that omentin-1 level was statistically associated with NPDR (OR=0.503, 95%CI: 0.291-0.871) and PDR (OR=7.862, 95%CI: 2.956-20.910); nesfatin-1 (OR=0.971, 95%CI: 0.953-0.989) and apelin (OR=3.266, 95%CI: 1.817-5.868) levels were statistically associated with NPDR.
Conclusion
Serum levels of omentin-1, nesfatin-1 and apelin were associated with different stages of DR among T2DM patients.

Stroke is the main cause of death and disability among adults in China and is characterized by high incidence, disability, mortality, and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang (DCQT) has a long history and proven efficacy in treating stroke. Clinically, DCQT is often used to treat stroke and its sequelae. However, the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research, the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage, reduce iron deposition, and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated signaling pathway and p38 mitogen-activated protein kinase (MAPK) signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT, this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials, pharmacodynamic material basis, safety evaluation, and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT, 11 of which are currently confirmed absorbed components. Among them, emodin, rhein, chrysophanol, aloe-emodin, synephrine, hesperidin, naringin, magnolol, and honokiol can be used as quality markers (Q-markers) of DCQT. The mechanism of DCQT in treating stroke is complex, involving regulation of inflammatory responses, neuronal damage, oxidative stress, blood-brain barrier, brain-derived neurotrophic factor, and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

Objective: To summarize the laboratory findings of a case of hemolytic disease of the fetus and newborn (HDFN) caused by Rh system anti-c antibodies and to review the literature, so as to explore the characteristics of anti-c HDFN. Methods: The ABO blood type, Rh blood type, direct antiglobulin test (DAT) results, and the presence of unexpected antibodies and their titers were determined by serological methods. The cases of anti-c HDFN in our laboratory in China and abroad were statistically analyzed, and the incidence of severe HDFN caused by anti-c, anti-D and anti-E was compared. Results: The blood type of the child was B (Rh CcDee) with a positive DAT. Anti-c antibody was detected in both serum and eluate, with a serum antibody titer of 4. The mother’s blood type was AB (Rh CCDee) with a negative DAT, and anti-c antibody was detected in the serum with a titer of 128. Among 20 cases of anti-c HDFN, 17 were DAT positive, and 9 (45%, 9/20) underwent blood transfusion or exchange transfusion. The incidence of severe HDFN was 47.60% (10/21) for anti-c, 47.60% (10/21) for anti-D and 31.30% (5/16) for anti-E. Conclusion: Maternal pregnancy and/or blood transfusion are the main reasons for the production of Rh alloantibodies such as anti-c. The prevention and management of anti-c should be similar to that of anti-D. Rh antigen-matched (five antigens of Rh blood group) transfusion is necessary for women of childbearing age to avoid antibody production, and Rh typing and antibody screening during prenatal examination is recommended to ensure early detection, intervention and treatment.

Objective To investigate the effect of embryonic inflammatory exposure on the response of mouse offspring to interphotoreceptor retinoid-binding protein(IRBP)-induced experimental autoimmune uveitis(EAU).Methods RNA transcriptome sequencing data from eyeballs of C57BL/6J mouse offspring born to mothers with active EAU were used to screen immune-associated differentially expressed genes in the eyes of the exposed offspring.Gene fragments overlapping in the two datasets were screened using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses to identify biological pathways associated with the gene fragments.Hub genes were identified from these intersecting genes by protein-protein interaction network analysis.EAU models of maternal uveitis were established by immunization with IRBP651-670,and expression levels of the pivotal genes in the offspring exposed to inflammation by maternal uveitis were examined by fluorescence quantitative polymerase chain reaction.EAU severity,T lymphocyte proliferation,and serum cytokines were detected to investigate the immune effect in offspring from mothers with an active inflammation response to IRBP induction.Results Microarray analysis identified 72 immune-related differentially expressed genes in exposed samples compared with the findings in control samples.These genes were mainly enriched in Toll-like receptor signaling,mitogen-activated protein kinase signaling,and B cell receptor signaling pathways.Protein-protein interaction network interaction analysis screened out four hub genes,Psmc5,Psmc3,Psmd4,and Psmd8,and mRNA levels of these four genes were increased in the adult offspring from mothers with active uveitis compared with the findings in healthy offspring.In addition,the group induced with 150 μg IRBP showed an increase in the severity of clinical and pathological outcomes in offspring with EAU affected by active inflammation,compared with the healthy offspring group(P=0.0087,P=0.0410).Meanwhile,T cell proliferation in the offspring was enhanced during the inflammatory activity stage and secretion of the inflammatory cytokines interleukin(IL)-17 and IL-6 was increased(P=0.0450,P=0.0300).Conclusions Psmc5,Psmc3,Psmd4,and Psmd8 may be important genes exacerbating uveitis in offspring of mothers with active uveitis,associated with increased T cell proliferation and production of IL-17 and IL-6.

The peroxisome proliferator-activated receptor gamma(peroxisome proliferator-activated receptor gamma,coactivator 1 beta,PPARGC1B)gene is an intranuclear receptor transcription fac-tor responsible for regulating the expression of target genes.To comprehend the characteristics and mutations of the PPARGC1B gene within the Sichuan yak population,the SNP loci of the PPARGC1B gene were identified through direct sequencing of PCR products.Additionally,the cod-ing region of the PPARGC1B gene was obtained via PCR amplification and sequencing.Bioinforma-tics analyses were conducted to predict protein-coding and mRNA secondary structure.This study identified four exon SNP mutation sites(E9-189A→C,E9-387G→A,E9-542C→T,and E9-554T→C)based on the single nucleotide polymorphism analysis of the PPARGC1B gene in Sichuan yaks.Notably,the E9-387G→A and E9-554T→C loci exhibited significant correlations with shear force and backfat thickness in Sichuan yaks.Subsequently,bioinformatics analysis of the four mutation sites revealed that the PPARGC1B protein is an acidic,unstable,non-transmembrane,and non-secretory hydrophilic protein with a coiled helix structure.It lacks a signal peptide and transmembrane region,predominantly functions in the nucleus,and features 106 phosphorylation sites,one glycosylation site,and one conserved RRM structure.The secondary structure comprises mainly α-helix and random coils.Although the protein structure of the PPARGC1B gene remained unchanged post-mutation,there were significant differences in mRNA secondary structure.These findings suggest that the polymorphic loci of the PPARGC1B gene in Sichuan yaks could serve as a theoretical basis for enhancing meat quality traits through molecular biological methods,presen-ting practical applications in breeding.
