Objective:To explore the mechanism of Danxing Zhishuang Prescription in the treatment of Parkinson's disease (PD) by combining network pharmacology with animal models.Methods:TCMSP, BATMAN database, Genecards, and OMIM databases were retrieved to obtain the active components and action targets of Danxing Zhishuang Prescription. Venny 2.1.0 was used to intersect drug targets and PD related genes, and a protein interaction network of the intersection targets was constructed using the STRING 12.0 platform. Topology analysis was performed using Cytoscape 3.10.0 software to identify the key targets of Danxing Zhishuang Prescription on PD; GO functional and KEGG pathway enrichment analysis was performed on key targets using the WeChat platform, and molecular docking was validated through AutoDockTools 1.5.7. Using a random number table method, mice were divided into a blank control group, a model group, and a Danxing Zhishuang Prescription group, with 20 mice in each group; except for the blank group, all other groups of mice were orally administered fisetin to prepare PD models; Danxing Zhishuang Prescription group was orally administered with concentrated Danxing Zhishuang Prescription at a dosage of 10.5 g/kg, while the blank group and model group were orally administered with 0.2 ml of physiological saline for 21 days; Western blot was used to detect the expressions of Akt1, Bcl-2, Bax, and α-Syn proteins.Results:359 intersection targets, 69 core targets, and 185 active components were obtained the treatment of PD with Danxing Zhishuang Prescription. The main active components included quercetin, kaempferol, phenylalanine, etc., and the key targets were AKT1, TP53, TNF, ESR1, etc. KEGG analysis revealed several key signaling pathways, such as AGE-RAGE, PI3K-Akt, fluid shear stress and atherosclerosis signaling pathways. The validation experiment results showed that compared with the model group, the expression of Bcl-2 protein was up-regulated ( P<0.01), and the expressions of Bax, Akt1, and α-Syn proteins were down-regulated in the Danxing Zhishuang Prescription group ( P<0.01). Conclusions:Danxing Zhishuang Prescription has the advantages of multi target and multi pathway treatment for PD. Its mechanism may be related to down-regulating the expressions of Bax, Akt1, and α-Syn proteins, improving brain blood supply, regulating neurotransmitter balance, inhibiting oxidative stress response, and promoting nerve regeneration.

Proteolysis-targeting chimeras (PROTACs) represent a promising class of drugs that can target disease-causing proteins more effectively than traditional small molecule inhibitors can, potentially revolutionizing drug discovery and treatment strategies. However, the links between in vitro and in vivo data are poorly understood, hindering a comprehensive understanding of the absorption, distribution, metabolism, and excretion (ADME) of PROTACs. In this work, 14C-labeled vepdegestrant (ARV-471), which is currently in phase III clinical trials for breast cancer, was synthesized as a model PROTAC to characterize its preclinical ADME properties and simulate its clinical pharmacokinetics (PK) by establishing a physiologically based pharmacokinetics (PBPK) model. For in vitro-in vivo extrapolation (IVIVE), hepatocyte clearance correlated more closely with in vivo rat PK data than liver microsomal clearance did. PBPK models, which were initially developed and validated in rats, accurately simulate ARV-471's PK across fed and fasted states, with parameters within 1.75-fold of the observed values. Human models, informed by in vitro ADME data, closely mirrored postoral dose plasma profiles at 30 mg. Furthermore, no human-specific metabolites were identified in vitro and the metabolic profile of rats could overlap that of humans. This work presents a roadmap for developing future PROTAC medications by elucidating the correlation between in vitro and in vivo characteristics.

Objective:To investigate the safety and efficacy of urinary microbiota transplantation(UMT)in treating interstitial cystitis(IC).Methods:A retrospective analysis of the clinical data of three patients with IC treated with UMT at the Central Hospital of Jiangnan University from May 2022 to August 2024. Three women(45,62,79 years)presented with urinary frequency(10 - 90 min intervals),urgency,dysuria,lower abdominal pain,and non-organic sleep disorder,with nocturia(2 - 15 episodes)causing sleep difficulty. Disease durations were 3,6,and 21 years. Prior antibiotic therapy failed. Preoperative urinalysis/culture(x2)ruled out bacterial cystitis,and diagnosed as interstitial cystitis(IC),with one of transient positive urine culture. Preoperative scores for case 1 were self-rating depression scale(SDS)of 49,self-rating anxiety scale(SAS)of 31,interstitial cystitis symptom index(ICSI)of 5,interstitial cystitis problem index(ICPI)of 2,brief urological problem scale of 50,genitourinary pain assessment scale of 10,and pain catastrophizing scale(PCS)of 0. For case 2,the scores were 60 of SDS,66 of SAS,9 of ICSI,11 of ICPI,50 of brief urological problem scale,28 of genitourinary pain assessment scale,and 34 of PCS. For case 3,the scores were 44 of SDS,48 of SAS,11 of ICSI,5 of ICPI,33 of brief urological problem scale,27 of genitourinary pain assessment scale,and 21 of PCS. Preoperative bladder hydro-distention showed mucosal hemorrhage including central block hemorrhage(Case 1),numerous spots(Case 2),and distinct sheets(Case 3). Preoperative urine 16S rRNA sequencing revealed low diversity,increased Gardnerella/ Bacteroides(opportunistic),and decreased Bacillus/ Streptococcus(beneficial). Two healthy young female donors had normal comprehensive tests covering blood/urine/stool,coagulation,CRP,immunity,liver/kidney function,lipids,infectious diseases,hormones,tumor markers,urine culture,TOUCH,and expanded quantitative urine culture. Donor urine 16S rRNA showed low pathogenic( Gardnerella/ Bacteroides)abundance. Donor midstream morning urine was catheter-collected,centrifuged,and the bacterial pellet resuspended in saline. Recipients underwent bladder irrigation pre-UMT. On UMT day,donor bacterial suspension was instilled via catheter with adverse event monitoring. Follow-up included clinic visits at 1 month and 1 year for symptom assessment,scale scoring,cystoscopy evaluating mucosal inflammation,hydrodistension checks,and telephone tracking of urinary symptoms every 2 - 3 months. Prognosis was assessed by symptom relief,scale score reduction,and mucosal recovery. Results:No adverse reactions occurred within 24 hours post-UMT in all 3 cases. Two patients showed same-day urinary urgency reduction;three reported relief from urinary frequency/urgency on postoperative day 7,with 2 - 3 hour daytime intervals and 0 - 5 nocturnal voids. Two patients experienced lower abdominal pain alleviation. Postoperative Week 1 urinalysis and urine cultures revealed no abnormalities. The 16S rRNA test showed a decrease in the abundance of harmful bacteria(e.g., Cupriavidus,Ureaplasm,Mycobacterium,Pseudomonas)and an increase in the abundance of beneficial bacteria( Dietzia,Halomonas,and Streptococcus),and the overall urobacterial structure was significantly improved and similar to that of the donor. Case 1 was followed up for 20 months,and the lab tests were normal,with SDS scales of 38,SAS of 20,ICSI of 3,ICPI of 2,brief urological problem scale of 44,genitourinary pain assessment scale of 10,PCS of 0,at 9 months post-op follow-up,indicating physical and mental improvement. The bladder hydro-distention revealed intact mucosa with only mild inflammation,which improved versus preoperative situation. Case 2 was followed up for 15 months,and the lab tests were normal,with SDS scales of 44,SAS of 34,ICSI of 4,ICPI of 2,brief scale of urinary problems of 0,genitourinary pain assessment scale of 9,PCS of 7,at 2 months post-op follow-up,showing improved anxiety/depression and quality of life. The hydro-distention showed decreased scattered hemorrhagic dots and mucosal inflammation. Case 3 was followed up for 13 months,with an increased leukocytes of urine and the other being normal for lab tests,and SDS scales of 35,SAS of 46,ICSI of 13,ICPI of 13,brief scale of urinary problems of 10,genitourinary pain assessment scale of 33,PCS of 11,at 13 months post-op follow-up,indicating physical and mental improvement. The hydro-distention revealed mucosal congestion,marked submucosal vasodilation,and inflammation decreased compared with preoperative situation. Conclusions:UMT alleviates urinary frequency,urgency,and pain in IC patients with sustained effects,significantly improves urine microecology,and shows no adverse events,positioning it as a viable intervention for IC.

Objective:To compare changes in retinal and choroidal blood flow in the macular area of eyes with idiopathic macular hole (IMH), fellow eyes, and normal eyes. Additionally, the correlation between these blood flow changes and the occurrence and development of IMH.Methods:A cross-sectional study. From January 2023 to January 2024, 47 patients (47 eyes) diagnosed with IMH (IMH group) in Department of Ophthalmology of The Second Hospital of Hebei Medical University were included in the study. The contralateral eye of IMH eyes was assigned to the contralateral eye group. Healthy volunteers with matched gender and age were selected as the normal control group. Swept-source optical coherence tomography angiography was used to acquire the vessel density (VD) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in the areas within 0-1 mm and 1-6 mm around the fovea, including the superior, temporal, inferior, and nasal regions. Additionally, the choroidal blood flow area (CBFA) and three-dimensional choroidal vascular index (3D-CVI) were measured. The minimum linear diameter (MLD) and base diameter (BD) of the IMH were manually measured. Spearman correlation analysis was performed to evaluate the correlation between the size of the IMH and the various vascular parameters.Results:Compared with the normal control group, the SCP-VD in the 3rd stage ( t=1.298, P=0.009) and 4th stage ( t=1.264, P<0.000) eyes in the IMH group was significantly decreased, with statistical significance; the DCP-VD ( t=1.958, 2.150, 1.712, 1.667; P=0.027, <0.000, <0.000, <0.000) and 3D-CVI ( t=0.027, 0.030, 0.024, 0.023; P=0.005, 0.003,<0.000, <0.000) in eyes of all stages were significantly decreased, with statistical significance; the CBFA in eyes of stages 2-4 was significantly decreased, with statistical significance ( t=0.027, 0.022, 0.021; P=0.028, 0.002, 0.002). Compared with the contralateral eye group, the DCP-VD and 3D-CVI in the IMH group were significantly reduced, with statistical significance ( Z=?3.289, ?2.704; P=0.001, 0.007). Pairwise comparisons between eyes of different stages in the IMH group showed that SCP-VD was significantly different between stage 2 and stage 4 ( t=1.776, P=0.008); DCP-VD was significantly different between stage 1 and stage 3, and stage 1 and stage 4 ( t=1.685, 1.661; P=0.002, 0.000). Correlation analysis showed that SCP-VD was negatively correlated with MLD and BD ( r=?0.508, ?0.408; P=0.002, 0.014); DCP-VD was negatively correlated with BD ( r=?0.410, P=0.013). Compared with the normal control group, the nasal CBFA in stage 3 and 4 IMH eyes ( t=0.149, 0.145; P=0.005, 0.002), and the nasal 3D-CVI in stage 1 and 3 IMH eyes ( t=0.030, 0.027; P=0.002,<0.000) were significantly decreased, with statistical significance. Conclusions:The SCP-VD, DCP-VD, CBFA, and 3D-CVI in IMH eyes were significantly reduced. SCP-VD showed a negative correlation with MLD and BD, while DCP-VD was only negatively correlated with BD.

The expression levels of PATL1 in pancar- cinoma,gastric cancer and normal tissues were analyzed by TCGA database.The expression level of PATL1 in 40 human gastric cancer tissues and paired adjacent tissues was evaluated by quantitative real-time PCR (RT-qPCR) . The Kaplan-Meier Plotter database was used to analyze the prognosis of PATL1 in gastric cancer patients.The gas- tric cancer cell line AGS was transfected with PATL1 interference vector,and the interference effect was evaluated by RT-qPCR. The effects of PATL1 on the proliferation and migration of AGS were detected by cell counting kit-8 ( CCK-8) ,Transwell test and scratch healing test.The effects of interference with PATL1 on the expression of cel- lular-myelocytomatosis viral oncogene ( c-Myc) and autophagy related 7 ( ATG7) proteins in gastric cancer cells were detected by Western blot assay.
Results :
RT-qPCR showed that the expression of PATL1 in human gastric cancer tissue was higher than that in normal gastric tissue (P<0. 001) ,and PATL1 was correlated with the progno- sis of patients with enteric gastric cancer (P<0. 000 1) .After PATL1 was knocked down,the number of prolifera- ting and migrating gastric cancer cells decreased (P<0. 05) .Western blot test results showed that the expression level of ATG7 protein decreased after PATL1 was knocked down (P<0. 05) .
Conclusion
PATL1 may inhibit the proliferation and migration of gastric cancer cells through crosstalk with c-Myc and ATG7 .
