OBJECTIVE To investigate the effects of subanesthetic dose of esketamine on postoperative anxiety and recovery in patients undergoing laparoscopic cholecystectomy. METHODS A total of 200 patients scheduled for laparoscopic cholecystectomy at Suzhou Ninth Hospital Affiliated to Soochow University from January 2023 to December 2024 were randomly assigned to control group （n＝100） and observation group （n＝100）. One minute before the initiation of anesthesia， patients in the control group received intravenous injections of Propofol emulsion injection， Sufentanil citrate injection， and Succinylcholine chloride injection. On this basis， patients in the observation group received an intravenous injection of Esketamine hydrochloride injection. The anxiety status of patients in both groups was compared， along with their general intraoperative conditions （including sufentanil dosage， duration of pneumoperitoneum， operative time， anesthesia time， and extubation time）， postoperative recovery， incidence of adverse reactions， and the need for dezocine rescue analgesia. Heart rate and mean arterial pressure， entropy index （state entropy and response entropy）， inflammatory marker levels [interleukin-6 （IL-6） and C-reactive protein （CRP）]， numerical rating scale （NRS） for pain intensity were compared between the two groups at different time points. RESULTS No significant differences were found between the two groups in pneumoperitoneum duration， operative time， anesthesia time，extubation time， incidence of postoperative dry mouth， entropy index or length of stay in the post-anesthesia care unit （P＞0.05）. Compared with the control group， the observation group showed significantly lower postoperative STAI-S scores， reduced intraoperative sufentanil consumption， decreased incidence of postoperative nausea， vomiting， and shivering， the need for dezocine rescue analgesia， as well as lower plasma IL-6 and CRP levels at 24 h after surgery， and NRS （P＜0.05）. The heart rate and mean arterial pressure of patients in the observation group at the start of surgery， end of surgery， and during extubation were all significantly higher than those in the control group （P＜0.05）. CONCLUSIONS Subanesthetic dose of esketamine can effectively alleviate postoperative anxiety， reduce intraoperative opioid consumption， suppress postoperative inflammatory response， relieve postoperative pain， and promote recovery in patients undergoing laparoscopic cholecystectomy.

BACKGROUND:Cellular senescence,which triggers the aging process of physiological decline in the body,is closely related to osteoporosis.With the development of aging research,significant progress has been made in the study of targeted clearance of senescent cells.Accordingly,senolytic cell therapy for osteoporosis based on this has attracted increasing attention.Current research on the association between aging and osteoporosis shows the characteristic of multidisciplinary intersection.However,existing reviews are mostly based on a single database(such as PubMed)and lack a systematic comparative analysis of Chinese and English literature.Therefore,it is of great academic value to integrate resources from multiple databases and systematically reveal the research status and hot trends of aging in the field of osteoporosis research.OBJECTIVE:To summarize the development,current status,hotspots,and future trends of research on aging in the field of osteoporosis over the past 20 years,so as to provide references for future related research.METHODS:We searched for research literature on the correlation between aging and osteoporosis in CNKI,WanFang,VIP and Web of Science Core Database.The search time span was from August 1,2004 to September 24,2024.Then,we used NoteExpress 4.0 for data cleaning and CiteSpace 6.3R1(Advanced)and Excel(2024)for literature analysis.RESULTS AND CONCLUSION:Since 2004,research on the correlation between aging and osteoporosis has shown a significant growth trend.Bibliometric analysis shows that(as of September 2024),and 1 275 English documents and 151 Chinese documents have been published,with the highest number of publications in China and the United States.In terms of publishing institutions,the Mayo Clinic ranked first,followed by Shanghai Jiao Tong University and the University of California system.As for core authors,Sundeep Khosla and Joshua Nicholas Farr were the authors with the most publications and citations,while Pei Lingpeng and Hui Bodi were the most worthy of attention in Chinese literature.After the keywords"aging"and"osteoporosis"and their synonyms were excluded,it was found that cellular senescence,senescence-associated secretory phenotype,signaling pathways,and targeted senolytic cell clearance therapy haven been the current research hotspots and theoretical frontiers.

Definitive chemoradiotherapy (dCRT) has become a cornerstone in the treatment of locally advanced esophageal cancer; however, local control remains suboptimal, and persistent lesions or locoregional recurrences after treatment are not uncommon. For patients without distant metastases but with local failure, whether surgical intervention can still offer curative potential remains a major clinical dilemma. Salvage esophagectomy (SE) offers potential long-term survival for selected patients, but this procedure is performed in the context of severe fibrosis, impaired local blood supply, and obscured anatomical planes following chemoradiotherapy, resulting in significantly higher perioperative risk compared to primary esophagectomy. Consequently, controversies exist regarding patient selection, preoperative restaging, choice of surgical approach, extent of lymphadenectomy, gastrointestinal reconstruction, and perioperative management. In recent years, with the refinement of restaging modalities such as PET/CT, the accumulation of experience in high-volume centers, and emerging evidence from clinical studies, the clinical role of SE has gradually shifted from a "high-risk salvage measure" to a "selective curative strategy aimed at achieving long-term survival in carefully selected patients". Nevertheless, standardized guidelines for patient selection, technical approaches, and perioperative management are still lacking. Based on current evidence and clinical experience, experts organized by the Integrated Esophageal Cancer Committee of Chinese Anti-Cancer Association systematically reviewed key issues regarding SE, including its definition, indications, preoperative evaluation, choice of surgical approach, lymphadenectomy, gastrointestinal reconstruction, and perioperative management, and formulated a Chinese expert consensus. This consensus aims to provide guidance for standardized assessment, appropriate referral, individualized surgical decision-making, and optimized perioperative management of patients with locoregional failure after dCRT. Ultimately, this will increase the likelihood of R0 resection, reduce the risk of severe complications, and promote the safer, more judicious, and standardized implementation of SE in high-risk scenarios.

ObjectiveTo observe the clinical efficacy and safety of Yanghe Xiaonang Decoction （阳和消囊汤， YXD） in the treatment of polycystic ovarian syndrome （PCOS）-related infertility with healthy qi deficiency and phlegm stasis syndrome. MethodsA total of 120 PCOS-related infertility participants with healthy qi deficiency and phlegm stasis syndrome were randomly divided into a treatment group and a control group in a 1∶1 ratio， with 60 cases in each group. The treatment group started taking YXD on the first day of the menstrual cycle， one dose daily， until the day of sexual intercourse when follicles matured and were released. Those without mature follicles or ovulation could take it until the 14th to 28th day. The control group was given oral letrozole at 2.5 mg daily starting on the 5th day of the menstrual cycle for 5 consecutive days. If the basal body temperature curve remained monophasic on the 28th day of the menstrual cycle， and no dominant follicle was detected by color Doppler ultrasound， estrogen plus progesterone or progesterone alone was administered for withdrawal bleeding， followed by a new treatment cycle. The treatment lasted for three consecutive menstrual cycles. Patients were followed up for 3 months upon confirmed pregnancy or after the completion of the 3rd treatment cycle. The clinical pregnancy rate， total effective rate， pregnancy rate， biochemical pregnancy rate， embryonic arrest rate， and ectopic pregnancy rate between the two groups were compared. Transvaginal color Doppler ultrasound was used for monitoring endometrial thickness， cyclic ovulation status， number of follicles between 2-9 mm， and the difference in transverse and longitudinal diameters of dominant follicles. The levels of endocrine hormone indicators including serum testosterone （T）， prolactin （PRL）， luteinizing hormone （LH）， follicle-stimulating hormone （FSH）， progesterone （P）， estradiol （E₂）， free testosterone （F-T）， androstenedione （ASD）， inhibin B （INH-B）， and anti-Müllerian hormone （AMH）， as well as the total traditional Chinese medicine （TCM） symptom scores before and after treatment were compared between the two groups. ResultsA total of 58 patients in each group were included in the statistical analysis. The clinical pregnancy rate in the treatment group was 39.66% （23/58）， higher than 22.41% （13/58） in the control group （P＜0.05）. The total effective rate in the treatment group was 96.55% （56/58）， higher than 79.31% （46/58） in the control group （P＜0.05）. The biochemical pregnancy rate and embryonic arrest rate in the treatment group were lower than those in the control group （P＜0.05）. The treatment group was superior to the control group in increasing endometrial thickness and reducing the number of 2-9 mm follicles at the 2nd and 3rd cycles， as well as in improving the cyclic ovulation status and the difference in transverse and longitudinal diameters of dominant follicles at the 3rd cycle （P＜0.05）. After treatment， the treatment group exhibited significant reductions in serum T， LH， F-T， ASD， INH-B， and AMH levels （P＜0.05）. The control group also showed significant decreases in LH， F-T， INH-B， and AMH levels （P＜0.05）. The levels of F-T， INH-B， and AMH in the treatment group after treatment were lower than those in the control group （P＜0.05）. The improvement of the total TCM symptom score in the treatment group was superior to that in the control group （P＜0.05）. ConclusionYXD can significantly improve the clinical pregnancy rate， reduce the rates of biochemical pregnancy and embryonic arrest， alleviate clinical symptoms， increase endometrial thickness， enhance dominant follicles， and improve endocrine hormone levels in PCOS-related infertility with healthy qi deficiency and phlegm stasis syndrome， showing good safety.

Objective To explore the impact of wearable devices in assisting disease monitoring on heart-focused anxiety in patients with tachyarrhythmias. Methods A cross-sectional study design was conducted. 305 patients with tachyarrhythmias who attended the department of cardiology of Zhongshan Hospital, Fudan University in Shanghai from July 2025 to December 2025 were enrolled as the research subjects, and clinical data of patients were collected. Univariate analysis and multiple stepwise regression analysis were used to analyze the impact of wearable devices in assisting disease monitoring on patients’ heart-focused anxiety. Results The mean score of heart-focused anxiety in the 305 patients with tachyarrhythmias was 33.16±9.70. Among them, 104(34.10%) patients used wearable devices in assisting disease monitoring. The results of univariate analysis and multiple stepwise regression showed that the use of wearable devices in assisting disease monitoring was an influencing factor for heart-focused anxiety (P＜0.05), and the patients who used wearable devices in assisting disease monitoring had a significantly lower level of heart-focused anxiety (P＜0.05). Conclusions The use of wearable devices in assisting disease monitoring is associated with a lower level of heart-focused anxiety in patients with tachyarrhythmias. Medical staff can guide patients to rationally use wearable devices in assisting disease monitoring on the basis of evaluating their needs and device operation capabilities.

Background: In acute and chronic renal inflammatory diseases, the activation of inflammatory cells is involved in the defect of erythropoietin (EPO) production. Ras guanine nucleotide-releasing protein-4 (RasGRP4) promotes renal inflammatory injury in type 2 diabetes mellitus (T2DM). Our study aimed to investigate the role and mechanism of RasGRP4 in the production of renal EPO in diabetes. Methods: The degree of tissue injury was observed by pathological staining. Inflammatory cell infiltration was analyzed by immunohistochemical staining. Serum EPO levels were detected by enzyme-linked immunosorbent assay, and EPO production and renal interstitial fibrosis were analyzed by immunofluorescence. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of key inflammatory factors and the activation of signaling pathways. In vitro, the interaction between peripheral blood mononuclear cells (PBMCs) and C3H10T1/2 cells was investigated via cell coculture experiments. Results: RasGRP4 decreased the expression of hypoxia-inducible factor 2-alpha (HIF2A) via the ubiquitination–proteasome degradation pathway and promoted myofibroblastic transformation by activating critical inflammatory pathways, consequently reducing the production of EPO in T2DM mice. Conclusion RasGRP4 participates in the production of renal EPO in diabetic mice by affecting the secretion of proinflammatory cytokines in PBMCs, degrading HIF2A, and promoting the myofibroblastic transformation of C3H10T1/2 cells.

Objective To investigate the value of the maximum standard uptake value(SUVmax)obtained with orbital SEPCT/CT for evaluating activity of thyroid-associated ophthalmopathy(TAO)and predicting curative efficacy.Methods A total of 96 patients with initially diagnosed TAO were retrospectively collected,including 71 with clinical activity score(CAS)≥3(active group)and 25 with CAS=2(inactive group).Data of orbital SEPCT/CT were collected,and the patients were treated with hormones or immunosuppressants for 3 months.CAS was performed again within 1 week after treatment,and orbital imaging was reviewed.The patients were divided into effective group and ineffective group according to treatment results.Pretreatment(pre)SUVmax(pre-SUVmax)and imaging agent uptake rate(UR)(pre-UR)in extraocular muscle were compared between active and inactive groups.Pre-CAS,post-treatment(post)CAS(post-CAS),as well as pre-SUVmax,post-SUVmax,pre-UR,post-UR and the difference of pre-and post-treatment CAS,SUVmax and UR(△CAS,△UR,△SUVmax)of extraocular muscle were compared between effective group and ineffective group.The correlations of SUVmax,UR and CAS were analyzed.Pre-CAS,pre-SUVmax and pre-UR were included in univariate and multivariate logistic regression analysis to screen the predictors of effective treatment of TAO.Results Pre-SUVmax and pre-UR of extraocular muscle in active group were higher than those in inactive group(both P＜0.05).Among 96 cases,70 were in effective group and 26 were in ineffective group.Pre-CAS,the proportion of pre-CAS≥3 scores,pre-SUVmax,pre-UR,△CAS,△SUVmax and △UR in effective group were all higher than those in ineffective group(all P＜0.05).Pre-SUVmax and pre-UR in extraocular muscle of TAO patients were positively correlated with pre-CAS(rs=0.419,0.395,both P＜0.001),while post-SUVmax and post-UR were positively correlated with post-CAS(rs=0.322,0.221,P=0.001,0.030),△SUVmax and △UR were positively correlated with △CAS(rs=0.368,0.206,P＜0.001,P=0.044).Pre-CAS≥3(OR=2.95)and pre-SUVmax(OR=4.22)were both independent predictors of effective treatment of TAO(both P＜0.05).Conclusion SUVmax obtained with orbital SEPCT/CT could be used to quantitatively assess TAO activity and predict curative efficacy.

Objective:To compare the survival outcomes of different subsequent treatment regimens in patients with locally advanced hypopharyngeal squamous cell carcinoma (HPSCC) who achieved partial response (PR) after neoadjuvant chemotherapy based on the gross tumor volume regression rate (GTVRR).Methods:This retrospective study included patients with locally advanced HPSCC treated at the Department of Head and Neck Surgery, Beijing Tongren Hospital, from January 2011 to December 2023. The cohort included 135 males and 3 females, aged from 35 to 77 years. All patients received 2-3 cycles of TPF regimen (paclitaxel+cisplatin+5-fluorouracil) neoadjuvant chemotherapy. Subsequent treatments included concurrent chemoradiotherapy or surgery combined with postoperative adjuvant radiotherapy. The impacts of different subsequent treatment modalities on the survivals and prognoses of patients were compared based on GTVRR thresholds of 50% and 70%. The χ 2 test was used to analyze influencing factors; survival analysis and intergroup comparisons were performed using the Kaplan-Meier method and Log-rank test; prognostic factors were assessed using univariate and multivariate Cox regression analyses. Results:The 5-year OS and PFS rates were 56.5% and 47.9%, respectively, while, the 10-year OS and PFS rates were 25.8% and 21.2%, respectively. The median OS was 75 months, and the median PFS was 48 months. The laryngeal function preservation rate for the entire cohort was 83.3%. The patients who underwent surgery combined with postoperative radiotherapy had significantly better OS and PFS outcomes than those treated with concurrent chemoradiotherapy ( P<0.05). Stratification based on GTVRR revealed that the surgery plus postoperative radiotherapy regimen was particularly effective for PR patients with a GTVRR of 30%-70%, showing significantly better OS and PFS compared to the concurrent chemoradiotherapy group ( P<0.05). Conclusion:The optimal subsequent treatment for PR-HPSCC may be surgery-based comprehensive treatment, particularly for patients with a GTVRR of 30%-70%. This study offers valuable insights for the stratified treatment of HPSCC, which could contribute to improving overall patient prognosis.
