ObjectiveCandidate genes related to the regulation of litter size traits in English Springer Spaniel breeding bitches are explored, and the genetic mechanism underlying fertility in this breed is investigated, in order to provide reference molecular markers for genomic selection of high fecundity. MethodsWhole genome resequencing was performed on English Springer Spaniel breeding bitches that had given birth to at least 3 litters, and the bitches were divided into a high-litter-size group and a low-litter-size group according to the average litter size. Selection signal analysis was used to obtain the intersection of fixation index (F_st) and nucleotide diversity (Pi) signals as highly selected regions, and candidate genes were screened based on gene annotation and functional enrichment analysis. ResultsThe average litter size in the high-litter-size group (7.41±1.27) was significantly higher than that in the low-litter-size group (3.82±1.20) (P＜0.05), and the total number of live offspring in the high-litter-size group (7.06±1.10) was extremely significantly higher than that in the low-litter-size group (3.67±1.11) (P＜0.01). A total of 3 155 706 SNPs were detected in the two groups, 63.09% of which were located in intergenic regions, 33.96% in intronic regions, and 0.38％, 0.57％, and 0.09％ in exonic regions, 3' untranslated regions (UTRs), and 5'UTRs, respectively. Among the SNPs in exonic regions, 5 256 were nonsynonymous variants, accounting for 43.55%. A total of 1 752 differential genes were identified after annotation screening. Gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG) enrichment analyses identified 13 candidate genes that may affect reproductive performance and litter size traits, including WDR35, SMAD7, RPGR, RERGL, PGRMC2, LOC482182, GIMD1, COX7B2, COX16, BMPR2, BMP6, BICD1, and SLC9C1. Their functions mainly involve reproductive hormone regulation, embryonic development, GTPase activation, and oocyte apoptosis. ConclusionEnglish Springer Spaniel breeding bitches have undergone significant artificial selection for litter size traits. These 13 candidate genes play key roles in oocyte maturation and regulation during early pregnancy, providing a new molecular basis for elucidating the genetic mechanism of canine reproductive traits.

Innovative drugs are defined as new chemical entities that play a vital role in the treatment and maintenance of human health. While single-target innovative drugs have achieved notable success, they face limitations in addressing the increasingly complex and precise spectra of diseases. The advent of multi-target innovative drugs offers new opportunities, supported by a growing body of pharmacological evidence. Herbal medicines are recognized as valuable sources of multi-target therapeutics due to their proven efficacy in treating complex diseases. However, the identification and validation of such drugs from herbal sources continue to pose significant challenges. This paper presents a comprehensive review of the literature on traditional Chinese medicine, integrated medicine, chemistry, and biology from 2015 to 2025. It summarizes the strategies employed in integrating traditional Chinese and Western medicine for innovative drug development, along with successful application cases. We believe these efforts will deepen understanding of the current landscape, accelerate the discovery of multi-target innovative drugs from herbal medicine, and contribute to addressing major human health challenges.

AIM:To explore the role of miR-195-5p in mediating trastuzumab resistance in gastric cancer and to validate its potential as a therapeutic target along with its target gene GPRC5A.METH-ODS:Trastuzumab-resistant gastric cancer cell lines(NCI-N87 and MKN45)were established.Cell viabili-ty under trastuzumab treatment was assessed us-ing CCK-8 assays.Expression levels of miR-195-5p were determined by RT-qPCR.Transfection with miR-195-5p mimics was performed to evaluate changes in trastuzumab sensitivity and prolifera-tion.GPRC5A expression was also measured by RT-qPCR,and the targeting relationship between miR-195-5p and GPRC5A was confirmed using a dual-lu-ciferase reporter assay.RESULTS:Parental cells showed higher sensitivity to trastuzumab than re-sistant cells,with miR-195-5p expression signifi-cantly lower in the latter.Overexpression of miR-195-5p in resistant cells enhanced trastuzumab sen-sitivity and reduced proliferation.GPRC5A was found to be upregulated in resistant cells,and miR-195-5p directly targeted GPRC5A,affecting cell pro-liferation under trastuzumab treatment.CONCLU-SION:miR-195-5p may regulate trastuzumab sensi-tivity in gastric cancer by targeting GPRC5A,sug-gesting potential as a molecular marker for trastu-zumab therapy guidance.

Valproic acid (VPA) is a traditional broad-spectrum antiepileptic drug, but long-term use of VPA will increase the risk of adverse drug reactions, with metabolic syndrome being the most common and often leading to infertility in men. Therefore, it is crucial to explore the relationship between epilepsy, VPA, metabolic syndrome and reproduction, the underlying pathogenesis, risk factors, and therapeutic measures. This exploration is essential for preventing adverse drug reactions and for guiding safe and rational use of drugs in clinical practice. This article summarizes the incidence of drug-induced metabolic syndrome and infertility in men with epilepsy who are treated with oral VPA, aiming to provide new research insights for optimizing treatment and reducing drug side effects.

Attention impairment in temporal lobe epilepsy (TLE) leads to other advanced cognitive impairments, such as memory and emotional recognition. Moreover, the severity of attention impairment determine the differences in strategies for preventing sudden unexpected death in epilepsy (SUDEP). Factors such as abnormal brain electrical discharges, sleep, and antiepileptic drugs are all associated with attention impairment. Neuroelectrophysiological observations have shown that abnormal electrical discharges interfere with the synchronization of cortical oscillations, and preventing the spread of abnormal epileptic discharges to subcortical activation structures helps reduce attention disorders. Neuroimaging reveals damage to the gray matter and white matter of the brain related to attention and poor connectivity of the whole-brain network. Therefore, early identification of attention impairment in TLE patients has become even more important. Treatment of attention impairment includes supplementing attention-related neurotransmitters, cognitive-behavioral therapy, surgical procedures, and neuromodulation techniques. This article mainly reviews the characteristics of attention impairment in TLE patients from the perspectives of clinical behavior, pathophysiology, and treatment, aiming to provide new insights for the early identification and management of attention impairment in TLE patients.

Objective:To observe any effect of combining interactive scalp acupuncture with constraint-induced movement therapy (CIMT) in treating the upper extremity motor function of children with spastic hemiplegic cerebral palsy.Methods:Fifty-seven children with spastic hemiplegic cerebral palsy were randomly divided into a control group of 28 and an observation group of 29. The control group was given conventional rehabilitation and routine CIMT, while the observation group was additionally provided with interactive scalp acupuncture. In the observation group the CIMT lasted for 30 minutes while the needles were retained. Then, after the needles were removed, the family administered simple rehabilitation training for 2.5 hours guided by a rehabilitation therapist. The treatments were administered 5 days per week for 3 weeks as a session, and the whole treatment consisted of 3 sessions. Before, as well as 1 month and 3 months after the treatment, upper extremity motor function in both groups was evaluated using the Melbourne assessment scale 2 (MA2) and the fine motor Peabody developmental motor scales. Muscle tone in the children′s elbow flexors was assessed using the modified Ashworth scale (MAS).Results:After both 1 and 3 months of treatment, the average MA2 scores of both groups were significantly better than those before treatment, with those of the observation group significantly superior to the control group′s averages. After both 1 and 3 months, both groups′ visual-motor integration scores, grasping ability scores and total scores had improved significantly, with those of the observation group significantly better than in the control group, on average. The MAS scores of both groups were also significantly better than before the treatment, but with no significant differences between the two groups at either time point.Conclusions:Interactive scalp acupuncture combined with constraint-induced movement therapy can significantly improve the upper extremity motor functioning and fine motor ability of children with spastic hemiplegic cerebral palsy.
