Objective:To evaluate the surgical management and clinical efficacy of endoscopic operation for tympanosclerosis (TS).Methods:A retrospective analysis was conducted on 228 patients with TS who underwent endoscopic surgery at Shaanxi Provincial People′s Hospital between January 2019 and December 2023. There were 79 males and 149 females, aged 18-68 years (median 50 years). Surgical management, perforation healing rate, pre-and post-operate hearing characteristics, and complications were analyzed. The air conduction threshold values at 500 Hz, 1 000 Hz, 2 000 Hz and 4 000 Hz, average air conduction pure tune audiometry (AC-PTA), and air-bone conduction (ABG) pre-and post-operation were compared. Statistical analysis was performed using SPSS 25.0.Results:All 132 cases of type Ⅰ tympanosclerosis underwent myringoplasty. Among 55 cases with type Ⅱ tympanosclerosis, 33 (60.0%) received typeⅠand 22 (40.0%) received type Ⅱ tympanoplasty. Of 16 cases with type Ⅲ tympanosclerosis, 10 (62.5%) underwent type Ⅰand 6 (37.5%) underwent type Ⅱtympanoplasty. Among 25 cases with type Ⅳ, 5 (20.0%) underwent type Ⅰ, 13 (52.0%) type Ⅱ, and 3 (12.0%) type Ⅲ tympanoplasty, while, 4 (16.0%) underwent tympanoplasty with autologous cartilage. The average follow-up period was 8.2 months (6 months to 3 years); The overall healing rate of the tympanic perforation was (97.8%)223/228. All cases exhibited improved air conduction hearing threshold at all frequencies, AC-PTA and ABG postoperatively. The differences between types Ⅰ, Ⅱ at 500 Hz, 1 000 Hz, 2 000 Hz, 4 000 Hz, AC-PTA and ABG were statistically significant (all P<0.001 for type Ⅰ, all P<0.05 for type Ⅱ). In type Ⅲ, improvements were significant for all tested parameters except at 4 000 Hz (all P<0.05) and no statistically significant difference were found in type Ⅳ. No severe complications such as profound sensorineural hearing loss or facial nerve paralysis were encountered. Conclusion:Totally, endoscopic transcanal surgery is an effective management for tympanosclerosis, providing favorable short-term hearing outcomes with an acceptable safety profile.

Objective:To explore the application value of high-resolution temporal bone CT and DW-MRI fusion technology in achieving precise diagnosis and anatomical localization of middle ear cholesteatoma during endoscopic surgery. Methods:Eighteen patients initially diagnosed with middle ear cholesteatoma in the Department of Otolaryngology Head and Neck Surgery, Shaanxi Provincial People's Hospital, from January to June 2024 were enrolled.Preoperative high-resolution temporal bone CT and DW-MRI were performed, and rtStation software was used for image fusion to construct CT-MRI fused images. The involvement of cholesteatoma in six anatomical subregions of the temporal bone was evaluated. Using surgical pathology as the gold standard, and combining surgical videos and anatomical records, the sensitivity, specificity, and accuracy of pure CT, pure DW-MRI, and CT-MRI fused images in evaluating middle ear cholesteatoma lesions were compared. Results:A total of 18 patients were included, and 17 cases were pathologically confirmed as middle ear cholesteatoma postoperatively. The sensitivity of the preoperative of preoperative CT was 100%, but the specificity was only 44.44%, with an overall accuracy of 72.22%; the sensitivity and specificity of DW-MRI evaluation were 81.46% and 85.19%, the accuracy was 83.33%, respectively. In contrast, the sensitivity and specificity of CT-MRI fusion image to the spatial localization of cholesteatoma were higher than that of DW-MRI alone（92.59% vs 81.46%; 98.15% vs 85.19%）, and the diagnostic accuracy was also significantly improved（95.37% vs 83.33%）. The Kappa values for the agreement between HRCT, DW-MRI, and CT-MRI segmentation localization and pathological results were 0.444, 0.667, and 0.907 respectively. The chi-square paired t-test confirmed statistically significant diagnostic differences between groups（P<0.001）. Results demonstrated that CT-MRI significantly outperformed HRCT and DW-MRI in diagnostic efficacy for segmental localization of primary posterior congenital middle ear cholesteatoma. Conclusion:High-resolution temporal bone CT combined with DW-MRI fusion technology demonstrates higher sensitivity, specificity, and accuracy in the diagnosis and spatial localization of middle ear cholesteatoma than single imaging modalities. It can provide more precise evaluation of lesion scope for endoscopic surgery, showing important clinical application value.

Objective:To systematically evaluate the clinical efficacy of oral ginger capsule or ginger powder in chemotherapy-induced nausea and vomiting in cancer patients.Methods:Computers searched Chinese Journal Full-text Database (CNKI), China Biomedical Literature Database (CBM), Wanfang Database, PubMed, EMbase, Web of Science, and Cochrane Library about oral chemotherapy in patients with cancer ginger correlation clinical curative effect of nausea and vomiting randomized controlled trial, supplemented by other search methods, the time range was built until July 2019. Quality evaluation and data extraction were performed independently by two investigators, and Meta analysis was performed by RevMan5.3 software.Results:A total of 12 articles and 13 studies were included, with a total of 1 105 patients. Meta-analysis showed that oral ginger capsule or ginger powder reduced the incidence of acute vomiting (risk ratio value was 0.76, 95% confidence interval was 0.59-0.98, P<0.05) and the severity of vomiting (mean difference value was-0.79, 95% confidence interval was-1.36--0.23, P<0.01), including the severity of acute vomiting (mean difference value was-1.39, 95% confidence interval was-2.72--0.06, P<0.05) and the severity of delayed vomiting (mean difference value was-0.46, 95% confidence interval was-0.82--0.10, P<0.05). However, there was no significant difference between the two groups in the incidence and severity of acute and delayed nausea ( P>0.05). Conclusions:This study demonstrates that oral ginger capsule or ginger powder is a complementary treatment for chemotherapy-induced nausea and vomiting in cancer patients, and more high-quality studies are needed to validate its clinical efficacy in the future.

Objective To analyze the relationship between pain sensation, emotion and recognition in three dimensions. Methods By using questionnaires which contained general information questionnaire, Cancer Pain Questionnaire, Self-reporting Inventory (SCL-90), Pain Beliefs and Perceptions Inventory (PBPI) to investigate pain sensation, emotion and recognition of 46 patients with cancer pain. Results There were 13(28.3%) cases sufferd from mild pain,17 (37.0%) cases were moderate pain, 16 (34.8% )cases were severe pain.As to the result of SCL- 90,patients showed obvious symptom in somatization, depression, anxiety and hostility.They holded deep belief of that pain was very mysterious. There was a significant correlation between pain severity and depression(rs=0.377) , anxiety(rs=0.388) on the condition that confidence level was 0.01;there was also a significant correlation between pain degree and interpersonal sensitivity(rs=0.308), hostility(rs=0.320) on the condition that confidence level was 0.05. As to pain beliefs, pain degree had a significant correlation with it in the dimension of pain as mystery (rs=0.529) and pain was persistent(rs=0.680) on the condition that confidence level was 0.01. Conclusions The survey shows a positive correlation between pain severity,emotion of pain(such as anxiety,depression, hostility and interpersonal sensitivity)and beliefs about pain as mystery or permanent.

Objective:To observe the effect of thoracic infusion of pseudomonas aeruginosa injection in malignant pleural effusion. Methods:A total of 90 patients with malignant pleural effusion were randomly divided into treatment group (31 cases),control group A (29 cases) and control group B(30 cases). Treatment group was treated with pseudomonas aeruginosa through intrathoracic infusion. Control group A and B were respectively treated with cisplatin and interleukin-2 through intrathoracic infusion. The clinical efficacy and adverse reaction were compared among the three groups. Results:The total effective rate of treatment group was 80.6%,the total effective rates of the control group A and B were 51.7%and 56.7%respectively.Compared with that of contral groups, the total effective rate of treatment group was higher, and the differences were statistically significant (P<0.05). The incidence of serious side effects and toxicity was lower in treatment group than in control groups. Conclusion:The effect of thoracic infusion of pseudomonas aeruginosa injection for malignant pleural effusion is significant, and the adverse reaction is mild. Thus it is worth to be promoted clinically.
