Objective: To explore the changes of mechanosensitive channels Piezos (Piezo 1 and Piezo 2) in neurogenic bladder (NB) of young rats and their effects，so as to provide reference for clinical search of new therapeutic targets. Methods: A total of 30 female young SD rats were divided into 5 groups based on random number table method：sham operation group (sham)，2-week nerve transection group (NB-2W)，6-week nerve transection group (NB-6W)，2-week nerve transection + Piezos inhibitor group (NB-P-2W) and 6-week nerve transection + Piezos inhibitor group (NB-P-6W)，with 6 rats in each group.The NB models were constructed by transecting the L6 and S1 spinal nerves of young rats.The NB-2W and NB-6W groups were not intervened after modeling，while the NB-P-2W and NB-P-6W groups were intraperitoneally injected with Piezos inhibitor GsMTx4 (10 mg/kg) every 2 days after modeling.Bladder cystometry and ultrasound were performed after 2 and 6 weeks of transection.The expressions of Piezos and fibrosis-related indexes (Collagen Ⅰ and α-smooth muscle actin) were detected in bladder tissues. Results: The results of bladder cystometry showed that the basal bladder pressure in NB-2W group was significantly increased，while it was slightly decreased but was still higher in NB-6W group than in the sham group (P<0.05).Basal bladder pressure was lower in NB-P-2W group than in NB-2W group，but was higher than that in the sham group; basal bladder pressure was lower in NB-P-6W group than in NB-6W group，but higher than that in the sham group (P<0.05).Compared with the sham group，the NB-2W and NB-6W groups had firstly increased and then decreased maximum cystometric capacity (MCC) (P<0.05).Compared with NB-2W group，NB-P-2W group had lower bladder leakage point pressure (BLPP)，but higher MCC and bladder compliance (BC) (P<0.05).Compared with NB-6W group，NB-P-6W group had significantly lower BLPP but higher MCC and BC (P<0.05).HE and MASSON staining and ultrasound results showed that，with the extension of nerve transection time，bladder fibrosis gradually worsened，the bladder wall became rough and thickened，calculi were visible inside，and hydronephrosis gradually appeared; the degree of fibrosis in NB-P-2W and NB-P-6W groups was less than that in NB-2W and NB-6W groups，and no hydronephrosis was observed in the upper urinary tract.In addition，Western blotting and immunohistochemical results showed that NB-2W and NB-6W groups had significantly higher relative expression levels of Piezos，Collagen Ⅰ and α-SMA than the sham group (P<0.01)，while NB-P-2W and NB-P-6W groups had lower relative expression levels of Piezos,Collagen Ⅰ and α-SMA than NB-2W and NB-6W groups (P<0.01). Conclusion: The increased expressions of mechanosensitive channels Piezos in NB young rats may be involved in the progression of bladder fibrosis，but its mechanism needs further study.

Objective:To explore the effects of mindfulness-based stress reduction(MBSR)on pain relief,anxiety and depression and quality of life in naval personnel with chronic pain.Methods:A total of 72 naval person-nel with chronic pain were randomly divided into MBSR group and routine intervention group.The routine interven-tion group received routine care,while the MBSR group received MBSR in addition to routine care.The Short-Form McGill Pain Questionnaire(SF-MPQ),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS),and 36-item Short Form Health Survey Scale(SF-36)were used at baseline and after 8 weeks of intervention.Results:The differences in the scores of 3 subjects of SF-MPQ,SAS,SDS and SF-36 in MBSR group at baseline and 8 weeks after intervention were higher than those in routine intervention group(Ps＜0.05).Conclusion:It suggests that mindfulnecs-based stress reduction could alleviate the degree of pain,anxiety and depression of patients with chronic pain in naval personnel and improve their quality of life.

Objective: This study aims to assess the impact of the metabolic risk score (MRS) on time to achieve complete remission (CR) of fertility-sparing treatments for atypical endometrial hyperplasia (AEH) and early endometrial cancer (EC) patients. Methods: Univariate and multivariate cox analyses were employed to identify independent risk factors affecting the time to CR with patients at our center. These factors were subsequently incorporated into receiver operator characteristic curve analysis and decision curve analysis to assess the predictive accuracy of time to CR. Additionally, Kaplan–Meier analysis was utilized to determine the cumulative CR rate for patients. Results: The 173 patients who achieved CR following fertility preservation treatment (FPT) were categorized into three subgroups based on their time to CR (<6, 6–9, >9 months). Body mass index (hazard ratio [HR]=0.20; 95% confidence interval [CI]=0.03, 0.38; p=0.026), MRS (HR=0.31; 95% CI=0.09, 0.52; p=0.005), insulin resistance (HR=1.83; 95% CI=0.05, 3.60; p=0.045), menstruation regularity (HR=3.77; 95% CI=1.91, 5.64; p=0.001), polycystic ovary syndrome (HR=−2.16; 95% CI=−4.03, −0.28; p=0.025), and histological type (HR=0.36;95% CI=0.10, 0.62; p=0.005) were identified as risk factors for time to CR, with MRS being the independent risk factor (HR=0.29; 95% CI=0.02, 0.56; p=0.021). The inclusion of MRS significantly enhanced the predictive accuracy of time to CR (area under the curve [AUC]=0.789 for Model 1, AUC=0.862 for Model 2, p=0.032). Kaplan–Meier survival curves revealed significant differences in the cumulative CR rate among different risk groups. Conclusion MRS emerges as a novel evaluation system that substantially enhances the predictive accuracy for the time to achieve CR in AEH and early EC patients seeking fertility preservation.

Objective To investigate the effect of TRPC5 on intermittent hypoxia-induced myocardial pyroptosis.Methods TRPC5 knock out(TRPC5-/-)and SD rats were each randomly divided into chronic intermit-tent hypoxia group(CIH group)and normoxia group(Control group)(n=6 for each group).The myocardial fibrosis in rats was visualized by Masson staining,the levels of serum inflammatory factors were measured by ELISA and the relative expression levels of TRPC 5 and pyroptosis-related proteins were determined by Western blotting.Results Masson staining showed that the collagen volume fraction in the TRPC5-/--CIH group was higher than that in the TRPC5-/--Control group and lower than that in the WT-CIH group.The ELISA results showed that the serum levels of IL-1,IL-6,and TGF-β in the TRPC5-/--CIH group were higher than those in the TRPC5-/--Control group and lower in the WT-CIH group.Western blotting results showed that the relative expression levels of pyroptosis related proteins caspase-1,NLRP3,GSDMD,and GSDMD-N in the TRPC5-/--CIH group were higher than those in the TRPC5-/--Control group and lower than those in the WT-CIH group.Conclusion TRPC5 deficiency alleviates myocardial pyroptosis and myocardial fibrosis induced by hypoxia.

The long-term presence of non-steroidal anti-inflammatory drugs (NSAIDs) in the environmental water samples not only affects the life safety of aquatic organisms and disturbs the ecoenvironment, but also poses a serious threat to human health. In this study, amino-functionalized Fe3O4 nanoparticles (Fe3O4-NH2) were firstly prepared by solvothermal method. Subsequently, polyethyleneimine (PEI) with a branched chain structure was successfully grafted onto Fe3O4 nanoparticles by Schiff base reaction in aqueous solution at room temperature using glutaraldehyde as a cross-linking agent, and a recyclable PEI-grafted magnetic nano-sorbent (Fe3O4@PEI) was synthesized and applied for the detection of NSAIDs in the environmental water samples. The compositional properties of Fe3O4@PEI were investigated by different characterization methods and the parameters affecting the extraction of NSAIDs were optimized. Due to high adsorption of Fe3O4@PEI for NSAIDs, the quantitative analysis of four NSAIDs in the environmental water samples, ketoprofen, naproxen, diclofenac and tolfenamic acid, was performed in combination with high-performance liquid chromatography. A good linear relationship between the chromatographic peak area and concentration was observed in the range of 1−500 µg/mL. The recoveries of the samples at three different spiked levels ranged from 85.6% to 107.8%; the intra-day precision was less than 7.8% (n=6); and the inter-day precision was less than 9.5% (n=3). The method is simple, rapid, accurate and reliable, and can be used for the analysis of NSAIDs in the environmental water samples．

Ischemic stroke （IS） is a serious cerebrovascular disease common in clinical practice. Targeting the pathogenesis of IS， intravenous thrombolysis for restoring blood flow is still the most effective therapy. However， intravenous thrombolysis has shortcomings such as increased bleeding risk， narrow therapeutic window， and contraindications， which limited its clinical application. Protection of the ischemic brain tissue before full recovery of blood flow is associated with the prognosis of IS. Studies have identified multiple pathways in the alleviation of the brain injury caused by IS， such as the mammalian target of rapamycin （mTOR） signaling pathway. Traditional Chinese medicine （TCM） has abundant therapies and unique advantages in the treatment of IS， especially in alleviating symptoms and improving the quality of life of patients. After the onset of IS， TCM can be integrated with Western medicine to play a role in the whole process of treatment， rehabilitation， and recurrence prevention as soon as possible， thus maximizing patient benefits. TCM has clinical significance for the recovery of neurological and motor functions after IS. Studies have shown that TCM can reduce the cerebral injury caused by IS by regulating and activating the mTOR signaling pathway， thereby regulating autophagy， inhibiting apoptosis of nerve cells， and reducing oxidative stress and inflammation. TCM exerts a positive effect for achieving cerebral protection and improving the prognosis of IS and provides new ideas for the prevention and treatment of IS. This article introduces the role of the mTOR signaling pathway in the pathogenesis of IS and reviews the research progress in the TCM regulation of this pathway in the treatment of IS， aiming to provide new therapeutic ideas and systematic scientific reference for the treatment of IS with TCM.

Objective　To timely understand the current status and distribution of nail snails (Oncomelania hupensis) in Tongjiang River channels in Zhenjiang City, providing a scientific basis for achieving the goal of eliminating schistosomiasis. Methods　From 2019 to 2023, nine Tongjiang River channels on the south bank of the Yangtze River under the jurisdiction of Zhenjiang City were selected as the monitoring area. Snail monitoring was carried out onshore and beach nail snails floats in the Tongjiang River channels, nail snails on attachments in hardened areas, snails induced by straw curtains, and snails carried by boats and domestic animals. Results　The monitoring results of shoreline snail from 2019 to 2023 showed that the snail situation in the Tongjiang River channel and its outer river bank remained relatively stable from 2019 to 2020; however, in 2021, under the influence of the Yangtze River flooding disaster in 2020, the area of snails increased significantly. In 2021, the area with snails in the Tongjiang River channel and the outer river bank increased by 45.70% (11.95/26.15) and 100.00% (20.00/20.00) compared to 2020; the average density of nails snails in the Tongjiang River channel and the outer river bank and the emergence rate of snail frames both showed a significant increase, rising by 94.73% (0.18/0.19) and 68.08% (8.68/12.75) compared to 2020, and by 122.73% (0.81/0.66) and 102.78% (43.26/42.09), respectively. The differences in the increase in the occurrence rate of spiked frames in the Tongjiang River channel Chili River and Renmin River were not statistically significant (χ2=0.329, P>0.05; χ2=0.646, P>0.05). From 2022 to 2023, the density of nail snails and the occurrence rate of framed snails in the Tongjiang River channel showed a decreasing trend (F=4.72, P=0.04 and χ2=372.58, P<0.01). The area of nail snails, density of live snails, and occurrence rate of framed snails in the outer river bank showed a decreasing trend (F=13.96, P=0.02; F=23.43, P<0.01; χ2=1 029.69, P<0.01). During the five years, no nail snails were detected in the ancient canal and 11 tributaries. From 2019 to 2023, 180 times of 3 003 kg of floating objects were salvaged, with a total of 148 live snails detected. A total of 17 live snails were captured on attachments in the hardened berm area; a total of 11 live snails were captured by straw curtain snail baiting;112 boats were inspected, and no snails were found; there were 112 boats surveyed, and no snails were found; 97 cattle were observed, and 2 cattle were found to carry 1 live snail on their hooves; 321 sheep were observed, and no snails were found on their hooves; and no infectious snails were found in the monitoring area in 5 years. Conclusions　Nail snails continue to exist in the Tongjiang River channel, and the risk factors for schistosomiasis transmission have not been completely eliminated. It is still necessary to carry out accurate monitoring of the snail situation in the Tongjiang River and the river bank, so as to grasp the risk of transmission in time and take emergency measures.

Objective To evaluate the clinical use of the baseline CT angiography(CTA)quantitative score(self-designed collateral circulation quantitative,SD-CCQ)in determining the collateral circulation compensation status in patients with acute ischemic stroke(AIS),as well as the reliability and accuracy of the SD-CCQ score and the Alberta Stroke Program Early CT Score(ASPECTS).Methods Retrospective analysis was made on the clinical and imaging data,including CT,CTA and DWI image data,of 84 patients who were admitted for acute ischemic stroke to the Department of Neurorehabilitation of Zhongshan Hospital of Traditional Chinese Medicine from January 2020 to December 2022.Their CTA source images were annotated using a multi-task deep learning method for vascular segmentation.The ASPECTS score and SD-CCQ score were then applied to the CTA images following vascular segmentation in order to assess the collateral circulation compensation of AIS patients.The Kappa test was used to assess the consistency of the two methods used to assess collateral circulation,and the multifactorial Logistic regression analysis was used to examine the relationship between the SD-CCQ and the prognosis of the AIS patients.Results ASPECTS score had good consistency with SD-CCQ score in evaluating collateral circulation in AIS patients(κ=0.65,P＜0.001),and the diagnostic accuracy of the latter for benign collateral circulation in AIS was 96.15％.Logistic regression analysis showed that the new collateral circulation score,baseline NIHSS,and DWI infarct volume were the main factors affecting the long-term prognosis of AIS patients.Conclusion The new scoring system SD-CCQ can be used to evaluate the compensatory status of collateral circulation in AIS patients,which may help in clinical treatment decision-making and prognosis prediction.

Purpose To investigate the expression and po-tential clinical value of heat shock protein 90α(Hsp90α)in co-lon adenocarcinoma.Methods The expression level of Hsp90αin colon adenocarcinoma and its relationship with clinicopatho-logical features,prognosis and immune cell infiltration were ana-lyzed by bioinformatics and immunohistochemistry.The prolifer-ation ability of colon cancer cells before and after Hsp90AA1 knockout was detected by CCK-8 cell proliferation assay and plate cloning assay.Results The bioinformatics tools showed that Hsp90AA1 was abnormally higher in colon cancer tissues than adjacent tissues,and the higher the expression level,the worse the prognosis of patients.The expression of Hsp90AA1 was positively correlated with the infiltration levels of CD4+T cells(Th2),CD8+T cells,myeloid inhibitory cells,Tregs cells,neutrophils,macrophages,M1 macrophages and M2 macropha-ges.Immunohistochemical results showed that the expression of Hsp90α in colon cancer tissues was significantly higher than in its adjacent tissues.The expression of Hsp90α was related to age(P＜0.05),not related to gender,tumor size,location,clini-cal classification,differentiation degree,tumor node metastasis,lympho-vascular invasion,perineural invasion(P＞0.05).The high expression of Hsp90α was an independent risk factor for the prognosis of colon cancer patients.The results of cell experi-ments showed that Hsp90AA1 knockout inhibited the growth and proliferation of colon cancer cells.Conclusion Hsp90α is highly expressed in colon adenocarcinoma,which may be a po-tential molecular marker for poor prognosis of colon adenocarci-noma.
