OBJECTIVE To analyze the correlation between styloid process related parameters and symptoms in patients with styloid process syndrome.METHODS A retrospective study was conducted on the 3D reconstruction CT results of the styloid process in 68 patients diagnosed with styloid process syndrome who visited the Department of Otolaryngology Head and Neck Surgery,the Second Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2024.The relationship between parameters such as styloid process length,angle,distance from styloid process tip to pharynx,and specific symptoms in patients with styloid process syndrome was analyzed.RESULTS Among 68 patients with styloid process syndrome,44 had unilateral symptoms and 24 had bilateral symptoms.The length of the styloid process on the symptomatic side of patients with unilateral symptoms(3.86±0.16)cm was significantly longer than that on the asymptomatic side(2.98±0.17)cm(Z=-2.191,P=0.028);The length of the styloid process on the side with severe symptoms in patients with bilateral symptoms(3.98±0.37)cm was also significantly longer than that in patients with mild symptoms(3.37±0.15)cm(t=2.448,P=0.024).Patients with styloid process syndrome mainly present with pharyngalgia(64.71%,44/68).There were no significant differences in the length,inclination angle,anteversion angle,and distance between the styloid process tip and the pharynx among those with unilateral pharyngalgia(n=29),bilateral pharyngalgia(n=15),and non pharyngalgia(n=24)(P>0.05).However,among the 68 patients with styloid syndrome,12 had calcification of the styloid hyoid ligament,while 56 did not.The incidence of unilateral pharyngalgia was significantly higher in patients with calcification of the styloid hyoid ligament than in patients without calcification(66.7%vs.35.7%,χ2=3.909,P=0.048).CONCLUSION The severity of symptoms in patients with styloid process syndrome is related to the length of the styloid process,and those with calcification of the styloid hyoid ligament are more likely to experience pharyngalgia.

Objective:To investigate the effects of fibroblast growth factor receptor 1(FGFR1)on the resistance of colorectal cancer(CRC)cells to oxaliplatin(OXA).Methods:An OXA-resistant cell line(HCT8/OXA)was established by treating HCT8 CRC cells with low-dose OXA for a long period in vitro.The CCK-8 assay was used to compare the viability of the HCT8 and HCT8/OXA cells after OXA treatment and to exam-ine their resistance to the anticancer drug.Second-generation high-throughput sequencing technology was used to identify differentially ex-pressed genes between the parental and drug-resistant cells.The expression of FGFR1 in the HCT8 and HCT8/OXA cells was detected by Western blot assay.Colony formation and flow cytometric assays were used to determine cell proliferation and apoptosis,respectively.The expression of PI3K/AKT signaling pathway-related proteins was detected using Western blot assay.Results:Compared with the levels in the HCT8 cells,the FGFR1 levels were significantly increased in the HCT8/OXA cells(P<0.01).FGFR1 overexpression in the HCT8 cells increased their drug resistance(P<0.01)and proliferation(NC+OXA:236.67±6.24;FGFR1+OXA:568.33±6.24)and decreased their apoptotic rate after OXA treatment(NC+OXA:27.83±0.85;FGFR1+OXA:17.47±1.25).FGFR1 knockdown in the HCT8/OXA cells reduced their drug resistance(P<0.01)and proliferative ability(Si-NC+OXA:411±8.29;Si-FGFR1+OXA:233.33±20.55)and increased their apoptotic rate(Si-NC+OXA:2.85±0.17;Si-FGFR1+OXA:14.42±0.77).FGFR1 inhibited the activity of the PI3K/AKT signaling pathway and cell apoptosis and improved the proliferation and drug resistance of the CRC cells.By contrast,an activator of the PI3K/AKT pathway blocked the effects of FGFR1 on this sig-naling pathway and drug resistance in the CRC cells.Conclusions:FGFR1 can inhibit the PI3K/AKT signaling pathway and thereby reduce the sensitivity of CRC cells to OXA.

Objective:To explore the applicability of modified comprehensive interventions in the treatment of non-severe dry eye syndrome in military pilots.Methods:A total of 88 military pilots with non-severe dry eye syndrome admitted to the Special Service Department of the 988th Hospital of the Joint Logistic Support Force between December 2021 and December 2023 were divided into an intervention group and a control group using the random number table method, with 44 cases in each. The intervention group received modified comprehensive interventions, while the control group underwent conventional treatment. The Ocular Surface Disease Index (OSDI), break-up time, tear meniscus height, changes in meibomian gland function, and levels of satisfaction of military pilots were compared between the 2 groups. The correlations between the OSDI, break-up time, tear meniscus height and levels of satisfaction were analyzed.Results:Before treatment, there was no significant difference in the OSDI between the 2 groups ( P>0.05). After 4 weeks of treatment, the changes in the OSDI of military pilots were smaller in the intervention group than in the control group ( t=3.21, P=0.002). After 2 and 4 weeks of treatment, the break-up time (both P<0.001) and tear meniscus height ( P<0.001, =0.012) of pilots in the intervention group exceeded those of the control group. In both groups, the break-up time (all P<0.001) and tear meniscus height (all P<0.001) kept increasing after treatment. After 4 weeks of treatment, there were significant differences in the distribution of meibomian gland function between the 2 groups ( Z=-2.55, -2.41, -2.29, P=0.011, 0.016, 0.022). Clinical care, procedure flow, and health education scored higher in the intervention group than in the control group during the survey on levels of satisfaction with the treatment ( t=6.55, 6.77, 3.63, all P≤0.001). The OSDI was negatively correlated with clinical care, procedure flow and health education ( r=-0.286, -0.275, -0.363, P=0.007, 0.010, 0.001) while the break-up time was positively correlated with clinical care and procedure flow ( r=0.248, 0.278, P=0.020, 0.009). Conclusions:The implementation of modified comprehensive intervention measures for dry eye syndrome in military pilots can effectively improve clinical symptoms and leave military pilots more satisfied.

Objective To explore the application value of vesicourethral anastomosis with maximal urethral length preservation(MULP)and bladder neck preservation(BNP)in laparoscopic radical prostatectomy(LRP)or robot-assisted laparoscopic radical prostatectomy(RALP)for high-risk prostate cancer(HRPC)in terms of early urinary continence and oncology.Methods Clinical data of 23 HRPC patients who underwent LRP(including RALP)with MULP and BNP in our hospital during May 2022 and Jan.2024 were retrospectively analyzed.Patients'basic information,surgical parameters,postoperative complications,oncological outcomes and urinary incontinence were collected and analyzed.Results All operations were completed successfully without conversion to open surgery.The operation time was(108±31)min,average blood loss(112±45)mL,hospital stay(5.5±1.5)days,urethral catheterization time(12.6±1.8)days,and no patient received blood transfusion during operation.The urinary continence rates at the time of catheter removal,and at 1,3,and 6 months after surgery were 39.1％,65.2％,73.9％,and 91.3％,respectively.Two patients had positive margins,both of which were at the neurovascular bundle.No patient developed surgery-related complications,urinary obstruction or fistula after surgery.Conclusion Vesicourethral anastomosis with MULP and BNP in LRP for HRPC can effectively improve patients'early urinary continence rate and postoperative quality of life without increasing the oncological risk.

OBJECTIVE To analyze the narrow-band imaging(NBI)endoscopic characteristics of recurrent early glottic carcinoma patients after undergoing CO2 laser surgery with a suspend laryngoscopy.METHODS A retrospective study was conducted on patients with early-stage glottic carcinoma(Ⅰ-Ⅱ stage)who received CO2 laser surgery under supportive laryngoscopy at the Department of Otolaryngology Head and Neck Surgery,the Second Affiliated Hospital of Xi'an Jiao Tong University from January 2017 to December 2023.The medical history,treatment methods,laryngoscopy(including common white light endoscopy and NBI endoscopy),imaging examinations,and pathological results of patients with recurrent glottic carcinoma were collected at different time points including preoperation,postoperative 1 month,postoperative 3 months,and postoperative 6 months.The endoscopic characteristics of NBI in patients with recurrent glottic carcinoma were summarized.RESULTS First,among 18 patients with early-stage glottic cancer recurrence after CO2 laser,the diagnostic rate of NBI endoscopy for laryngeal cancer recurrence(88.89％,16/18)was significantly higher than that of common white light endoscopy(55.56％,10/18)(χ2=4.985,P=0.026).The intraepithelial papillary capillary loop(IPCL)was classified as a vertical vessel according to ELS in all relapsed patients.However,according to Ni classification,the IPCL of the 72.22％(13/18)were classified as type V,while the IPCL of 27.78％(5/18)showed suspicious abnormal neovascularization(punctate or dilated and curved).The proportion of patients with abnormal IPCL on the surgical surface at 1 month,3 months,and 6 months postoperatively was 0.00％,27.78％(5/18),and 61.11％(11/18),respectively,with statistically significant differences(χ2=16.164,P<0.001),which indicated that the longer the follow-up time for recurrent laryngeal cancer patients,the higher the proportion of patients with abnormal IPCL on the surface of the surgical area under NBI endoscopy.CONCLUSION For early glottic carcinoma after CO2 laser surgery with a suspend laryngoscopy,the appearance of suspicious new blood vessels with type Ⅴ IPCL and punctate or dilated curvature under NBI endoscopy may indicate early recurrence of laryngeal cancer.

OBJECTIVE To analyze the changes of temporary abnormal intraepithelial papillary capillary loop(IPCL)in the surgical area of early glottic laryngeal cancer after CO2 laser resection.METHODS A retrospective study was conducted on early-stage glottic carcinoma patients who visited the Department of Otolaryngology,Head and Neck Surgery at the Second Affiliated Hospital from January 2017 to November 2023.Patients who underwent CO2 laser surgery accepted electronic laryngoscopy examination at 1 month,3 months,and 6 months postoperatively(including white light endoscopy and narrowband imaging endoscopy(NBI),and their medical history,treatment methods,laryngoscopy images,imaging data,and pathological results before and after treatment were systematically collected.The changes in laryngoscopy characteristics at different follow-up times after surgery were analyzed.RESULTS This study included 55 patients with non recurrent early glottic carcinoma who underwent CO2 laser surgery.At 1 month,3 months,and 6 months after surgery,there were significant differences in the proportion of patients with pseudomembrane coverage(72.73%vs.25.45%vs.7.27%),granulation formation(60.00%vs.34.55%vs.1.82%),and abnormal IPCL(23.64%vs.7.27%vs.0.00%)on the surface of the surgical area(P<0.001),and abnormal IPCL(mainly type Va and Vb)can be observed under NBI endoscopy from 1 month to 3 months after surgery.Within 6 months after surgery,the pseudomembrane detachment,granulation regression,scar formation,and abnormal IPCL in the surgical area disappeared.CONCLUSION Early glottic carcinoma patients may experience temporary abnormal IPCL within 3 months after receiving CO2 laser resection,but the abnormal IPCL could disappear within 6 months after surgery for some patients.Therefore,close observation is necessary within 6 months after surgery and there is no need for urgent biopsy.

Objective:To investigate the efficacy and safety of different treatment duration of dual therapy including vonoprazan and low-dose amoxicillin in Helicobacter pylori ( H. pylori) eradication. Methods:From December 1, 2022 to November 30, 2023, a total of 150 H. pylori-infected patients who underwent primary treatment in the Affiliated Changzhou No.2 People′s Hospital of Nanjing Medical University were recruited. The patients were divided into 10-day treatment group and 14-day treatment group with 75 patients in each group by random number table method. Patients of both groups were treated with vonoprazan (20 mg each time, twice per day) combined with amoxicillin (0.75 g each time, 3 times per day), and the treatment duration was 10 and 14 days, respectively. Intention-to-treat (ITT) and per-protocol (PP) analyses were used to evaluate the eradication efficacy of H. pylori of the 10-day treatment group and 14-day treatment group. PP analysis was used to compare the incidence of adverse events between the 2 groups. Cost-effectiveness analysis was performed to evaluate the economic efficiency of the 2 treatment regimens. Identified factors affecting the eradication rate in the 10-day treatment group based on the PP. Independent sample t-test and chi-square test were used for statistical analysis. Results:In ITT and PP analysis, a total of 75, 75 patients and 70, 72 patients were included in the 10-day treatment group and 14-day treatment group, respectively. The results of ITT analysis showed that the eradication rates of 10-day treatment group and 14-day treatment group were 86.7% (65/75) and 90.7% (68/75), respectively. The results of PP analysis showed that the eradication rates of the 2 groups were 92.9% (65/70) and 94.4% (68/72), respectively, and the differences were not statistically significant (both P>0.05). The results of PP analysis showed that the incidences of adverse events of the 10-day treatment group and 14-day treatment group were 12.9% (9/70) and 9.7% (7/72), respectively, and the difference was not statistically significant( P>0.05). The cost-effectiveness ratios of the 10-day treatment group and 14-day treatment group were 3.29 and 4.19 yuan/%, respectively. The optimal cut-off values were 63.5 kg for body weight and 1.73 m 2 for body surface area to affect the H. pylori eradication rate. The H. pylori eradication rate of patients with body weight ≤ 63.5 kg was higher than that of patients with body weight >63.5 kg (100.0%, 42/42 vs. 82.1%, 23/28), and the H. pylori eradication rate of the patients with body surface area≤1.73 m 2 was higher than that of patients with body surface area>1.73 m 2 (100.0%, 45/45 vs. 80.3%, 20/25), and the differences were statistically significant ( χ2=5.61 and 6.91, P=0.018 and 0.009). Conclusions:The 10-day combination therapy of vonoprazan and low-dose amoxicillin is a safe and effective primary treatment regimen for H. pylori eradication. Body weight and body surface area are influencing factors of the eradication rate.

Objective:This study aimed to construct a risk prediction model for obstructive sleep apnea（OSA） related hypertension based on the nomogram, and to explore the independent risk factors for OSA-related hypertension, so as to provide reference for clinical treatment decision-making. Methods:The clinical data of OSA patients diagnosed by polysomnography from October 2019 to December 2021 were collected retrospectively and randomly divided into training sets and validation sets. A total of 1 493 OSA patients with 27 variables were included. The least absolute shrinkage and selection operator（Lasso） logistic regression model was used to select potentially relevant features and establish a nomogram for OSA-related hypertension.The performance and clinical benefits of this nomogram were verified in terms of discrimination, calibration ability and clinical net benefit. Results:Multivariate logistic regression showed that body mass index（BMI）, family history of hypertension, lowest oxygen saturation（LSaO2）, age and cumulative percentage of total sleep time with oxygen saturation below 90% were independent risk factors for OSA-related hypertension. Lasso logistic regression identified BMI, family history of hypertension, LSaO2 and age as predictive factors for inclusion in the nomogram. The nomogram provided a favorable discrimination, with a C-indexes of 0.835（95% confidence interval[CI ]0.806-0.863） 0.865（95%CI 0.829-0.900） for the training and validation cohort, respectively, and well calibrated. The clinical decision curve analysis displayed that the nomogram was clinically useful. Conclusion:Compared with cumulative percentage of total sleep time with blood oxygen saturation below 90%, LSaO2 may have a greater impact on the incidence of OSA-related hypertension, and the effects of different times and degrees of hypoxia on OSA-related hypertension should be further explored in the future. Apnea hypopnea index involvement is weak in predicting OSA-related hypertension, and the blood oxygen index may be a better predictor variable. Furthermore, we established a risk prediction model for OSA-related hypertension patients using nomogram, and demonstrated that this prediction model was helpful to identify high-risk OSA-related hypertension patients. This model can provide early and individualized diagnosis and treatment plans, protect patients from the serious.
