Objective: To explore the efficacy of vonoprazan fumarate in the treatment of laryngopharyngeal reflux disease（LPRD） evaluated by the Chinese version of the RSS-12 scale. Methods:A total of 100 LPRD patients treated in the otolaryngology-head and neck surgery outpatient clinic of our hospital were randomly divided into two groups（50 cases each）. The observation group was treated with vonoprazan fumarate（20 mg, once daily）, and the control group was treated with esomeprazole enteric-coated capsules（20 mg, twice daily） for 12 weeks. The selected observation indicators in this study included RSI, the Chinese version of RSS-12, and RFS scores before and after treatment. Results:Prior to treatment, there was no statistically significant difference in the Chinese version of RSS-12, RSI, and RFS between the two groups（P>0.05）. After 8 and 12 weeks of antacid treatment, both the Chinese version of RSS-12 and RSI significantly decreased in both group （P<0.05）. The changes in symptoms were particularly noticeable between 0-8 weeks of treatment according to the Chinese version of RSS-12 and RSI. After 12 weeks of treatment, the RFS scores significantly decreased compared to pretreatment levels （P<0.05）. After 12 weeks of antacid treatment, according to the Chinese version of RSS-12, 80% of patients in the observation group showed a good therapeutic response, compared to 64% in the control group; according to RSI, 90% of patients in the observation group showed a good therapeutic response, compared to 84% in the control group. There was no statistically significant difference in the treatment effect between the two groups after 12 weeks of treatment（P>0.05）. Conclusion:Vonoprazan fumarate can significantly improve the symptoms and signs of laryngopharyngeal reflux, and their treatment effect is not inferior to proton pump inhibitors. Compared with RSI, the Chinese version of RSS-12 can serve as a new screening tool for clinical diagnosis of LPRD in China.

Objective To analyze the expression of triggering receptors expressed on myeloid cells-1(TREM1)in esophageal cancer and its relationship with the overall survival rate of patients,and to explore its effect on the migration ability of KYSE30 cell in e-sophageal cancer.Methods The expression of TREM1 in tumor tissue and its relationship with patient prognosis were analyzed by bioin-formatics and clinical specimens.KYSE30 cells were selected and divided into negative control(NC)group,negative control+lipopo-lysaccharide(NC+LPS)group,interference TREM1 group,interference TREM1+lipopolysaccharide group.Compare the changes in cell proliferation and migration ability of different groups using Transwell method;Western blot was used to detect changes in EMT-relat-ed proteins among different groups;real-time quantitative polymerase chain reaction(RT-qPCR)was used to compare interleukin-1β(IL-1β),interleukin-6(IL-6)and interleukin-8(IL-8)of different groups of cells;overexpression of TREM1 interfered with IL-6,and the changes in EMT-related proteins were compared at this time.Results TREM1 was highly expressed in esophageal cancer tissue and serum,and was associated with lymph node metastasis and overall survival rate in patients;TREM1 can promote the in-vasion and metastasis of KYSE30 cells,and the related mechanism may be by promoting the expression of IL-6,thereby initiating EMT in esophageal cancer cells.Conclusion TREM1 is highly expressed in esophageal cancer tissue,and promotes tumor EMT through up-regulation of IL-6,which is beneficial for the invasion and metastasis of esophageal cancer,leading to poor prognosis in patients.

Objective To study the mechanical response of tibial prostheses and the distal tibial cancellous bone after implantation of radial and axial functionally graded materials(FGM)into the ankle joint.Methods Three FGM were used:titanium alloy-bioactive glass composite FGM(FGM-Ⅰ),titanium(Ti)alloy-ideal bone elastic composite FGM(FGM-Ⅱ),and Ti alloy-hydroxylapatite composite FGM(FGM-Ⅲ).A three-dimensional finite element model of total ankle arthroplasty(TAA)was established,and the simulation software ABAQUS was used for secondary development based on Fortra.By changing the volume fraction,the mechanical properties of the FGM tibial prosthesis can be adjusted both axially and radially.The stress distributions of the tibial prosthesis and cancellous bone after FGM axial and radial tibial component implantation in the standing position were analyzed.Results Compared with Ti alloy tibial prosthesis,three kinds of FGM could effectively reduce the stress concentration on the tibial prosthesis,and the overall effect of FGM-Ⅲ tibial prosthesis was better than that of FGM-Ⅰ and FGM-Ⅱ tibial prosthesis;the radial distribution of FGM could effectively reduce the maximum von Mises stress of the prosthesis.For the tibial cancellous bone,the three types of FGM radial tibial prostheses and FGM-Ⅲ axial tibial prostheses could effectively increase the distal stress,thus,relieving the stress shielding on the cancellous bone;the FGM-Ⅲ radial tibial prosthesis was the most effective in improving the stress level of the cancellous bone.Conclusions FGM-Ⅲ radial ankle prosthesis can effectively reduce the stress concentration phenomenon and the stress shielding effect on the prosthesis to prolong its life,with potential application prospects.

The malignant degree of cholangiocarcinoma is high, and the early diagnosis is difficult. The vast majority of patients are unresectable when they are diagnosed. The patients have low quality of life and short survival cycle. Traditional radiotherapy and chemotherapy have poor efficacy and lead to side effects, and thus lack effective control measures for cholangiocarcinoma. Endoscopic retrograde cholangiopancreatography (ERCP) is an important method for diagnosing and treating biliary tract diseases. Photodynamic therapy (PDT) is a new local treatment for cholangiocarcinoma. In recent years, ERCP-mediated PDT treatment of cholangiocarcinoma has gradually emerged. ERCP-mediated PDT can effectively relieve the symptoms of patients with cholangiocarcinoma, improve the patients' quality of life, prolong the survival cycle, and is expected to become a new treatment for cholangiocarcinoma.
