		                        			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.

		                        			 Aim To explore the molecular mechanism of Selaginella moelledorffii Hieron. in the treatment of laryngeal cancer. Methods According to the relevant literature reports, the chemical constituents of S. moellendorffii were obtained, and the active ingredients were screened out through the SwissADME database, and the targets were screened through the PharmMapper database. The laryngeal cancer-related targets were collected by searching OMIM and other databases, and the Venny 2.1.0 online platform was used to obtain the intersection of the two. Protein interaction analysis of the potential targets was performed using the STRNG platform. GO functional analysis and KEGG pathway analysis was carried out using DAVID database. Visual networks were built with Cytoscape 3.8.0 software. Molecular docking was validated by SYBYL-X 2. 0 software. MTT method, Hoechst 33258 staining method and Western blotting were also used for validation. Results At the molecular level, a total of 110 active ingredients of S. moellendorffii and 82 drug targets were screened out, 1,608 targets related to laryngeal cancer, and intersection of 34 targets. GO analysis yielded 135 entries, and KEGG analysis yielded a total of 61 pathways. Molecular docking results showed that the 11 key active ingredients such as 2", 3"-dihydrooch-naflavone wood flavonoids and 4 core target proteins such as MAPK1 had 95. 5% of good docking activity. At the cellular level, SM-BFRE was screened for its strongest inhibitory effect on laryngeal cancer cell proliferation through MTT assay. Furthermore, Hoechst 33258 staining showed that the decrease in Hep-2 cell viability produced by SM-BFRE was related to cell apoptosis. Finally, Western blot verified that SM-BFRE inhibited PI3K/Akt/NF through inhibition- K B/COX-2 pathway to induce apoptosis in laryngeal cancer cells. Conclusions To sum up, it fully reflects the multicomponent, multi-target, and multi-channel synergistic effect of S. moellendorffii in the treatment of laryngeal cancer, and provides a theoretical reference for further elucidation of the mechanism of action of S. moellendorffii in the treatment of laryngeal cancer.

		                        			Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

		                        			Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

		                        			【Objective】 To investigate the expressions of containing CKLF like MARVEL transmembrane domain gene 6 (CMTM6) and ras protein activator like 2 (RASAL2) in prostate cancer tissues, and to analyze the relationships between the above factors and the clinicopathological characteristics and prognosis of prostate cancer patients. 【Methods】 The prostate cancer tissues and adjacent tissues of 80 prostate cancer patients admitted to Zhumadian City Center Hospital during Feb.2018 and Feb.2020 were collected.Expressions of CMTM6 and RASAL2 were detected with immunohistochemical method.The relationship between the expressions of CMTM6 and RASAL2 and the clinical pathological characteristics of prostate cancer were analyzed.The survival curve was plotted with Kaplan-Meier method.The prognostic factors were analyzed with multivariate Cox regression. 【Results】 The positive expression rate of CMTM6 in prostate cancer tissues was 67.50%, which was obviously higher than 38.75% in adjacent tissues (χ2=13.277, P<0.001).The positive expression rate of RASAL2 in prostate cancer tissues was 47.50%, which was obviously lower than 73.75% in adjacent tissues (χ2=11.546, P=0.001).The expressions of CMTM6 and RASAL2 were not related to patients’ age, tumor size and tissue differentiation (P>0.05), but to TNM staging, Gleason score, lymph node metastasis and preoperative PSA level (P<0.05).Survival curve showed that the 3-year survival rate of positive CMTM6 expression patients was 61.11% (33/54), which was obviously lower than that of negative patients, which was 88.46% (23/26) (χ2=5.940, P=0.015).The 3-year survival rate of positive RASAL2 expression patients was 81.85% (31/38), which was obviously higher than that of negative patients, which was 59.52% (25/42) (χ2=4.887, P=0.027).Cox multivariate regression showed that Gleason score, lymph node metastasis, preoperative PSA level, CMTM6, and RASAL2 were independent influencing factors of prognosis (P<0.05). 【Conclusion】 The positive expression rate of CMTM6 in prostate cancer tissues is significantly higher than that in paracancer tissues, while the positive expression rate of RASAL2 in prostate cancer tissues is significantly lower than that in paracancer tissues. Both CMTM6 and RASAL2 are closely related to the clinical pathological characteristics and prognosis of prostate cancer patients, and may provide reference for the prognosis.

		                        			Cardiovascular diseases are a group of disorders of the heart and blood vessels, primarily including coronary heart disease, stroke, and other diseases. It is the world’s leading cause of death, and its incidence is increasing yearly. Hypertension is a major risk factor for cardiovascular disease. Wnt signaling comprises a series of highly conservative cascading events controlling fundamental biological processes. Wnt signaling pathways include the canonical Wnt pathway (or Wnt/β-catenin pathway), the non-canonical planar cell-polarity pathway, and the non-canonical calcium-dependent pathways. Abnormal Wnt signaling promotes cell proliferation and differentiation, cardiac malformations, various malignancies, so drugs targeting Wnt signaling play a great therapeutic potential. Wnt/β‑catenin pathway is involved in the occurrence and development of cardiovascular diseases such as atherosclerosis and stroke by regulating cell proliferation, migration, apoptosis, blood-brain barrier permeability, inflammation, oxidative stress, and immune response. Based on the latest research progress, this review summarizes the role of Wnt/β‑catenin signaling in cardiovascular diseases, in order to provide new ideas for the prevention and treatment of cardiovascular diseases.

		                        			Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.
