Objective To investigate the feasibility of hernia needle assisted suture in single-incision laparoscopic transabdominal preperitoneal repair(SIL-TAPP).Methods From February 2023 to April 2024,20 young patients with indirect inguinal hernia were treated with SIL-TAPP.A 2 cm curved incision was made at the navel,and a three channel port was inserted for transabdominal preperitoneal repair.A hernia needle was inserted into the affected side lower abdominal wall to assist in one handed suturing and closure of the peritoneum.Results All the operations were successful.The operation time was 85-125 min,with an average of(91.3±10.0)min.The closure of the peritoneum took 18-30 min,with an average of(23.4±3.2)min.Intraoperative blood loss was 5-25 ml.The Visual Analogue Scale(VAS)score at 24 h after surgery was 1-3 points.Postoperative hospitalization lasted 1-5 d,with an average of(2.4±1.0)d.After surgery,one patient had seroma in the groin area and one patient had fat liquefaction in the umbilical cord.All the patients were followed up for 8-22 months after operation,with an average of(15.3±3.4)months.No recurrence after operation or umbilical hernia was noted.Conclusion The use of hernia needle assisted suturing to close the peritoneum during SIL-TAPP surgery can reduce the difficulty of one handed suturing,especially suitable for the early stage of single-incision laparoscopic surgery.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

METHODS Titank C18 (250 mm×4.6 mm, 5 μm) column was used; 0.1% phosphoric acid solution(A)-acetonitrile(B) was used as the mobile phase with gradient elution; detection wavelengths: geniposide at 238 nm, aloe-emodin, rhein, emodin, chrysophanol, physcion and mangiferin at 254 nm, berberine hydrochloride at 265 nm, baicalin, wogonoside, baicalein, and wogonin at 280 nm, praeruptorin A and praeruptorin B at 321 nm. The flow rate was 1.0 mL·min−1 and the column temperature was 35 ℃; the injection volume was 10 μL. RESULTS The linear ranges of geniposide, mangiferin, baicalin, berberine hydrochloride, wogonoside, baicalein,aloe-emodin, rhein, wogonin, emodin, praeruptorin A, chrysophanol, physcion and, praeruptorin B were 4.96−223.17, 0.84−42.22, 18.76−938.16, 4.46−223.17, 4.86−243.10, 1.59−79.32, 0.76−38.17, 1.03−51.49, 1.59−79.40, 1.21−60.72, 1.80−90.06, 0.91−45.48, 1.04−51.83 and 0.86−43.23 μg·mL−1, with r all ≥ 0.999 9. The RSDs of instrument precision, stability and reproducibility tests were <3%, and the average recoveries in sample(n=6) were >90%, with the RSDs <3%. CONCLUSION The method is simple and reproducible and can provide a scientific basis for improving the quality standard of Qingfei Yihuo tablets.

Gout is a common metabolic disease. Gouty arthritis is associated with the deposition of urate crystals in the synovial fluid or para-articular soft tissues, which often affects the hands, feet, wrists, ankle and knees joints. However, the shoulder joint is unusual involved. In the present study, a 49-year-old male patient complained of right shoulder pain for 9 months and aggravating with limited range of motion for 2 weeks. Physical examination showed that the external rotation was 10° and hand back was S 5 of the right shoulder. The MRI showed shoulder joint effusion and intra-articular loose bodies. The patient was admitted to the hospital with the diagnosis of "loose bodies of the right shoulder with synovial chondromatosis possibly". Arthroscopic examination revealed that a lots of urate crystals were deposited on synovium, cartilage and rotator cuff. Loose bodies removal and joint debridement were performed. Histopathologic examination of the specimen demonstrated synovitis hyperplasia with urate crystals deposition. Shoulder gouty arthritis characterized by pain and limited movement. The imaging of tophi depends on the calcium-containing deposits. Tophus with calcium deposits can be found on X-ray and CT. MRI can not only evaluate the tophus but also the evaluate the other intra-articular pathologies. Due to no typical manifestations and specific images of shoulder gouty arthritis, pathological diagnosis is the "gold standard". Shoulder arthroscopy provide a minimal invasive technique in diagnosing and treating of the shoulder disease. Undoubtedly, it could be a reliable diagnosis and treatment method for shoulder gouty arthritis.
