Objective:To evaluate the feasibility and outcomes of transnasal endoscopic clipping of the paraclival internal carotid artery (ICA) in skull base surgery.Methods:The paraclival ICA was anatomically dissected in cadaveric head specimens. The clinical data of 15 patients with skull base lesions involving the ICA who admitted to the Department of Otorhinolaryngology Head and Neck Surgery at Tianjin Huanhu Hospital from January 2021 to December 2023 were retrospectively analyzed. Among them, 4 patients underwent transnasal endoscopic clipping of the paraclival ICA and concurrent lesion resection. The surgical methods were summarized, and the key points and indications of this technique were analyzed.Results:Intraoperative clipping of the ICA was successful and hemostatic in all 4 patients. Postoperatively, 3 patients had no complications, while 1 patient developed delayed ischemic cerebral infarction. Two patients were cured, 1 patient was maintained on immunotherapy, and 1 patient died. During follow-up, the clip was in situ in 1 patient, had detached in another, and was obscured by temporal muscle coverage in the remaining 2 patients.Conclusions:Transnasal endoscopic clipping of the paraclival ICA represents a potential option for managing the ICA in skull base surgery. However, it carries significant risks and limitations, mandating careful patient selection based on specific circumstances.

Objective A high sodium(HS)diet is believed to affect bone metabolism processes.Clarifying its impact on osseointegration of titanium(Ti)implants holds significant implications for postoperative dietary management of implanted patients. Methods This investigation probed the impact of sodium ions(Na+)on neovascularization and osteogenesis around Ti implants in vivo,utilizing micro-computed tomography,hematoxylin and eosin staining,and immunohistochemical analyses.Concurrently,in vitro experiments assessed the effects of varied Na+concentrations and exposure durations on human umbilical vein endothelial cells(HUVECs)and MC3T3-E1 cells. Results In vivo,increased dietary sodium(0.8%-6.0%)led to a substantial decline in CD34 positive HUVECs and new bone formation around Ti implants,alongside an increase in inflammatory cells.In vitro,an increase in Na+concentration(140-150 mmol/L)adversely affected the proliferation,angiogenesis,and migration of HUVECs,especially with prolonged exposure.While MC3T3-E1 cells initially exhibited less susceptibility to high Na+concentrations compared to HUVECs during short-term exposure,prolonged exposure to a HS environment progressively diminished their proliferation,differentiation,and osteogenic capabilities. Conclusion These findings suggest that HS diet had a negative effect on the early osseointegration of Ti implants by interfering with the process of postoperative vascularized bone regeneration.

Objective:To investigate the lung cancer incidence and mortality in 2016 and their trends from 2002 to 2016 in shanghai. Methods:The data of incidence and death on lung cancer in shanghai from 2002 to 2016 were obtained from the Shanghai Municipal Center for Disease Control and Prevention population-based cancer registry and Vital Statistics System.Lung Cancer incidence and mortality stratified by age of diagnosis or death,gender and age-group were analyzed.The number of cases and deaths,proportion,crude rates,age-specific rates,age-standardized rates,corresponding truncated age-standardized rates(35-64 years)and cumulative rates were calculated.Segi's 1960 world standard population was used for calculating age-standardized rates of incidence and mortality as well as truncated age-standardized rates.Trends in age-standardized rates of incidence and death for lung cancer in Shanghai from 2002-2016 were estimated by Joinpoint analysis and characterized by the annual percent change(APC). Results:The new lung cancer cases and deaths were 14 395 and 9 170 in Shanghai in 2016.The crude rate of incidence was 99.41/105,and the age-standardized rate of incidence was 39.76/105.New cases of lung cancer accounted for 19.34％of all malignant tumors in shanghai,ranking the first in the incidence spectrum of malignant tumors.The crude rate of mortality was 63.33/105,and the age-standardized rate was 21.57/105.Deaths of lung cancer accounted for 24.78％of all malignant tumor deaths in shanghai,ranking the first in the mortality spectrum of malignant tumors.The age-standardized rates of incidence and mortality for males were higher than those for females.The age-specific numbers and rates of incidence and mortality increased with age.The age-specific number and rate of incidence reached the peak at the age group of 60-64 years and 80-84 years respectively,and those of mortality peaked at the age group of 80-84 years and older than 85 years respectively.The incidence of lung cancer increased from 33.70/105 in 2002 to 39.76/1 05 in 2016 in Shanghai.Joinpoint analyses showed that the age-standardized rate of lung cancer incidence remained stable from 2002 to 2010(APC=-0.79,t=-1.46,P=0.175)but showed a significant upward trend with an average annual increase rate of 5.12％from 2010 to 2016(APC=5.12,t=6.97,P＜0.001).The standardized mortality showed a downward trend with an average annual decrease rate of 0.87％from 2002 to 2016(APC=-0.87,t=-2.87,P=0.013). Conclusion:The incidence of lung cancer in Shanghai during 2002-2016 presented an upward trend while the mortality of lung cancer showed a gradual downward trend.There are differences in the incidence and mortality of lung cancer among different gender and age groups.

OBJECTIVE To study the effects and m echanism of eriocalyxin B （EriB）on epithelial -mesenchymal transition （EMT）of colon cancer cells . METHODS The colon cancer cells HT 29 and HCT 116 as research objects . Scratch-healing assay and Transwell assay were used to detect the effects of EriB on migration and invasion of two kinds of cells . Western blot method was used to detect the effects of EriB （1.0 μmol/L），EriB+Wnt/β-catenin signaling pathway agonist Licl （1.0 μmol/L EriB+ 10 mmol/L Licl）or EriB+Wnt/ β-catenin signaling pathway inhibitor XAV 939（1.0 μmol/L EriB+ 10 μmol/L XAV 939）on the expressions of EMT related proteins [E-cadherin，N-cadherin，Snail] and Wnt/ β-catenin signaling pathway related proteins [β-catenin，c-myc， cyclin D 1，TCF4]. RESULTS EriB can significantly inhibit the invasion and migration of two kinds of cells （P＜0.01）. EriB significantly reduced the protein expressions of N -cadherin，Snail，β-catenin，c-myc，cyclin D 1 and TCF 4 while increases the protein expression of E -cadherin（P＜0.05 or P＜0.01）. After EriB combined with Licl ，the protein expressions of β-catenin，c- myc，cyclin D 1 and TCF 4 in the two kinds of cells were reverse d（P＜0.05 or P＜0.01）. After combined with XAV 939，the protein expressions of β-catenin and N -cadherin were further down -regulated（P＜0.05 or P＜0.01）；the protein expression of E -cadherin was further up -regulated（P＜0.01），while migration rate was decreased significantly （P＜0.01）. CONCLUSIONS EriB can inhibit the epithelial -mesenchymal transition of colon 19SXHZ0351） cancer cells by inhibiting the activation of Wnt/ β -catenin

Although traditional treatment for Graves′ disease(GD) displays some effects, it is imperative to explore new treatment methods. Based on the pathogenesis of GD, biologic agents developed by consumption of B lymphocytes and acting on thyroid stimulating hormone receptor(TSHR), such as monoclonal antibodies, TSHR antagonists and epitopes, can provide more options for patients with GD, and some new drugs are expected to be put into clinical practice. By restoring the damaged immune system and maintaining normal thyroid function continuously, it can avoid the disadvantages of conventional therapies such as long-term treatment, induction or aggravation of Graves ophthalmopathy, permanent hypothyroidism, and other complications. Preliminary experience suggests that thermotherapy is effective and safe for patients with refractory GD. In addition, the traditional Chinese medicine improves the symptoms and thyroid function of GD patients.The emergence of new therapeutic modalities and techniques will provide new approaches for the future treatment of GD and help clinicians to make the best decision.

Late-onset hypogonadism (LOH) is an age-related testosterone deficiency syndrome. With the increasing aging of society, LOH results in impaired quality of life of middle-aged and elderly men. Although domestic and international guidelines have been issued in recent years, and the management of LOH became more standardized, numerous controversies still remained in the diagnosis of LOH, the benefits of testosterone replacement therapy (TRT) and therapeutic targets. Based on comparison of different guidelines, this review focuses on age cut-off , specific signs and symptoms of LOH, diagnostic cut-off level of testosterone, the advantages and disadvantages of TRT treatment, and non-testosterone therapy.

Objective:To establish and evaluate a predictive model for recurrence risk of Graves′ disease after antithyroid drugs(ATD) withdrawal.Methods:Among 308 patients with newly onset Graves′ disease taking ATD from 2012 to 2019, 170 patients who completed follow-up were enrolled and divided into relapse and remission groups according to whether hyperthyroidism reoccurred within 2 years after ATD withdrawal to establish the discovery cohort. An internal validation cohort was constructed by repeating the sampling with bootstrap. Cox regression analysis was used to screen risk factors and establish a predictive model, named Graves′ Recurrence Evaluation System(GRES). The differentiation and accuracy of GRES model were evaluated and compared with the GREAT score.Results:Of 170 patients, 90 Graves′ disease cases relapsed within 2 years after ATD withdrawal. According to Cox regression analysis, family history of Graves′ disease, younger age(<30 years), grade Ⅱ-Ⅲ goiter, high level of TRAb(≥13 IU/L), large thyroid volume(≥26.4 cm 3) and low 25(OH) D(<14.7 ng/mL) were included in the predictive model: PI=0.672×family history+ 0.405×age+ 0.491×severity of goiter+ 0.808×TRAb+ 1.423×thyroid volume+ 0.579×25(OH) D. PI≥1.449 was associated with a higher risk of recurrence after drug withdrawal. The GRES model has good prediction in assessing Graves′ disease relapse within 2 years after ATD withdrawal and better than GREAT score. Conclusion:GRES model can be used to evaluate the recurrence risk within 2 years for patients with newly onset Graves′ disease after ATD withdrawal, and facilitate clinicians to reasonably select treatment modalities in order to improve the remission rate.
