Objective To explore the feasibility of magnetic compression technique (MCR) in the treatment of severe single mid-ureteral stricture in a rabbit model. Methods After 10 female New Zealand rabbits were selected, the distal end of the right ureter was ligated with silk thread. Two weeks after the operation, when the right ureter was dilated, the mid-ureter was ligated again with silk thread to create a severe single mid-ureteral stricture animal model. Longitudinal incisions were made at the upper and lower ends of the ligation site, and cylindrical NdFeB magnets with central holes (sub-magnets and main magnets) were placed to anastomose and recanalize the mid-ureteral stricture. The magnets were adjusted to the appropriate position to automatically align and attract each other. The longitudinal incision sites of the ureter were sutured with 6-0 Prolene thread, and the abdominal cavity was closed layer by layer. The operation time was recorded. X-ray films were taken every two days to confirm the position of the magnets and record the time of magnet detachment. Three weeks after the operation, the anastomotic specimens were obtained, and the formation of the anastomosis was evaluated with gross observation and histological staining. Results Two weeks after ligation, all experimental rabbits showed obvious dilation of the right ureter. The mid-ureteral ligation and placement of the male and female magnets were successfully completed in all 10 experimental rabbits, with an operation time of (24.00±5.15)minutes. The male and female magnets attracted each other well. X-ray examination showed that the magnets detached and entered the distal ureter (14.0±1.9) days after magnetic compression. The recanalization of the severe single mid-ureteral stricture was successfully achieved. The gross specimens and histological examination of the anastomosis showed that the anastomosis remained patent and the mucosal healing was good. All experimental rabbits survived well after the operation without serious complications. Conclusion MCT provides a new idea and novel method for the treatment of mid-ureteral stricture. This study confirmed the feasibility of this technique in treating severe single mid-ureteral stricture in a rabbit model. The operation is relatively simple and has potential for clinical application.

Autism Spectrum Disorder （ASD） is a neurodevelopmental disorder with rapidly increasing global prevalence， characterized by core symptoms of social communication deficits and stereotyped repetitive behaviors. Although genetic predisposition， abnormal epigenetic regulation， perinatal environmental exposure， and nutritional-metabolic imbalances are recognized as major risk factors， the precise etiological mechanisms remain incompletely understood. Current clinical management primarily relies on behavioral interventions， with limited pharmacological options accompanied by adverse effects. Recent studies have demonstrated the unique therapeutic value of active components from Chinese herbal medicine in ASD intervention. This article reviews the mechanisms underlying various Chinese herbal active components in ASD treatment， including improvements in synaptic dysfunction， blood-brain barrier impairment， neurotransmitter regulation， cerebellar dysfunction， immune dysregulation and neuroinflammation， oxidative stress， programmed neuronal cell death， and lipid metabolism. These bioactive components exhibit multi-target and multi-pathway regulatory effects， providing novel therapeutic strategies and directions for ASD.

Huangqintang， with its accurate efficacy， is a classic formula specialized in treating dysentery recommended and promoted by medical experts from successive generations， and it was included in the Catalogue of Ancient Classic Prescriptions （the Second Batch， Han Chinese medicine prescriptions） published by the National Administration of Traditional Chinses Medicine （TCM） in 2023. The method of bibliometrics was applied in this study to conduct textual research on the classic formula Huangqintang and provide a literature reference for the development of modern preparations of Huangqintang. A total of 2 026 pieces of ancient literature were searched with "Huangqintang" as the key word， and 23 pieces of effective data were selected， involving 15 ancient TCM books. The historic evolution， composition， dosage， origin， processing methods， preparation and decocting methods， efficiency， and application of Huangqintang were carefully reviewed. The results showed that Huangqintang was first recorded in the Treatise on Febrile Diseases written by ZHANG Zhongjing. It has the effect of clearing heat， stopping dysentery， regulating the middle， and downbearing counterflow and has become one of the classic formulas widely used in clinical practice. Because of its accurate efficacy， medical experts from later generations have modified it from its original composition. Though many prescriptions have different names， it is the manifestation of physicians' inheritance and development of the thought of ZHANG Zhongjing. Ancient literature showed this prescription had wide indications yet centered on digestive system diseases such as dysentery and abdominal pain. Modern applications of Huangqintang involve digestive， respiratory， ophthalmology and otolaryngology， gynecological， skin， musculoskeletal system， and connective tissue， and this prescription has great potential in treating ulcerative colitis， diarrhea， acute enteritis， and damp-heat dysentery. Through a systematic textual excavation and review of the ancient literature about Huangqintang， the paper has confirmed its key information， so as to provide a scientific basis for the clinical application and new drug development of classic formulas.

Energy metabolism disorders are a critical factor contributing to cognitive dysfunction.Astrocytes,as key suppliers of energy substrates to neurons,help to sustain normal cognitive function via their extensive energy metabolism activities in the brain,coordinated by various energy supply mechanisms.Imbalances in astrocyte-neuron energy metabolism coupling lead to abnormal neuronal activity,thereby driving the pathogenesis and progression of Alzheimer's disease(AD).It is therefore essential to investigate the pathological mechanisms and therapeutic targets associated with AD from the perspective of energy metabolism to support the future development of AD treatments and interventions.Traditional Chinese medicine(TCM),characterized by multi-component and multi-target effects,has shown potential efficacy for regulating cerebral energy metabolism,suggesting that modulating brain energy metabolism may represent a significant pathway by which TCM might ameliorate AD.This review systematically elucidates the mechanistic role of the dysregulation of astrocyte-neuron bioenergetic coupling in the pathogenesis and progression of AD,and critically evaluates recent advancements in therapeutic interventions mediated by TCM.

[Objective]To investigate the potential value of thyroid hormones in cerebrospinal fluid in predicting autism-like behaviors induced by hypothyroidism in pregnant rats.[Methods]Twelve pregnant Wistar rats were randomly divided into a control group and a hypothyroidism group(hypothyroidism model group).Offspring from both groups had serum and cerebrospinal fluid levels of thyroid-stimulating hormone(TSH),total triiodothyronine(TT3),total thyroxine(TT4),free triiodothyronine(FT3),and free thyroxine(FT4)levels in serum and cerebrospinal fluid.Ultrasonic vocalization tests were conducted on postnatal day 2(P2),day 7(P7),and day 14(P14),while behavioral tests using the three-box social interaction test were performed on day 21(P21).[Results]Compared with the control group,free T4(FT4)levels in the cerebrospinal fluid of the hypothyroidism group were significantly reduced during the developmental period(P0-P21;P2:P<0.05;P7:P<0.05;P14:P<0.01;P21:P<0.01),with no statistical difference between the two groups only at P0(P>0.05).In the ultrasonic vocalization(USV)tests,the number and duration of USVs in offsprings from the hypothyroidism group were significantly reduced compared with those of the control group on P2,P7 and P14:for USV counts(P2:P<0.05;P7:P<0.001;P14:P<0.01);for USV duration(P2:P<0.05;P7:P<0.001;P14:P<0.001).In the three-box social tests,offsprings of the hypothyroidism group showed significantly reduced sniffing time with unfamiliar rats at P21 compared to the control group(all P<0.001).The FT4 levels in cerebrospinal fluid had a significantly positive correlation with USV counts(P7:r=0.883,P<0.05;P14:r=0.902,P<0.05)and sniffing time with unfamiliar rats(r=0.814,P<0.01).[Conclusion]Measuring free T4 in cerebrospinal fluid can predict autism-like behaviors in offsprings of rats induced by hypothyroidism during pregnancy.

[Objective]To explore the effects of astragalin(AST)on autophagy and apoptosis of astrocytes in the L4-5 dorsal horn of the spinal cord in mice with inflammatory pain induced by complete Freund's adjuvant(CFA).[Methods]Twenty-four male C57BL/6 mice,aged six months,were randomly assigned to four groups:control group,saline group,CFA model group,and CFA+AST group,six mice in each group.The inflammatory pain model was established by injection of 10 μL CFA into the right lateral malleolus fossa.The saline group were injected with an equal amount of normal saline at the same site.The inflammatory pain mice in CFA+AST group were further treated with AST(60 mg/kg)intraperitoneally once a day for 21 consecutive days.Multiplex immunofluorescence staining was used to detect the coexpression of autophagy-related factors including ATG 12 and Beclin-1,apoptosis-related factors including Cleaved-Caspase3 and Caspase9,and the astrocyte marker such as GFAP in the L4-5 spinal dorsal horn of the mice in each group.Western blot was used to examine the protein expression levels of autophagy-related proteins(ATG12,Beclin-1)and apoptosis-related proteins(Caspase 3,Caspase 9)in the L4-5 spinal dorsal horn of mice.[Results]Immunofluorescent staining showed that in the L4-5 dorsal horn of the spinal cord,the fluorescence intensity of ATG12(P<0.000 1)and Beclin-1(P<0.000 1)was significantly increased,while that of Cleaved-Caspase 3(P<0.001)and Caspase 9(P<0.000 1)was decreased in the CFA+AST group when compared to the CFA model group.Furthermore,AST could inhibit the activation of astrocytes.Western blot further confirmed that AST significantly upregulated the expression of ATG12(P<0.000 1)and Beclin-1(P<0.000 1)in the L4-5 spinal cord of CFA mice,and downregulated the expression of Caspase 3(P<0.01)and Caspase 9(P<0.001).[Conclusions]AST promotes autophagy of astrocytes and inhibits their apoptosis in the L4-5 spinal dorsal horn of CFA mice.
