OBJECTIVE: To investigate the feasibility of applying ultracision-harmonic scalpel in tonsillectomy. METHOD: Thirty-one cases treated with tonsillectomy which applied with nasal endoscope and ultracision-harmonic scalpel (ultrasonic scalpel group) and 31 cases treated with routine operation (routine group) respectively. The operating time and blood loss during operation and the degree of pain and the region of inflammation humidity as well as hospitalization days were observed. RESULT: All indexes in ultrasonic scalpel group were lower than that in the routine group, including operating time and blood loss during operation, and they were obviously difference in statistics (P < 0.01). CONCLUSION The application of ultracision-harmonic scalpel in tonsillectomy was safe, efficient and feasible, and would have a nice application prospect during ear-nose-throat operation.

Objective To assess the clinical value of lung ultrasound (LUS) B-lines in diagnosis of rheumatoid arthritis (RA) associated interstitial lung diseases (RA-ILD).Methods Forty-five consecutive patients with RA who underwent a high resolution computed tomography (HRCT) scan of the chest,were also examined by LUS for detection of B-lines(within 1 month independently in all patients).The B-lines score was obtained by summing the number of total 50 inter-costal spaces (ICSs) of chest wall.Pulmonary fibrosis was quantified by HRCT as previously described by the 30-point Warrick score.Results B-lines score significantly correlated with the Warrick score [(r=0.778,95％CI(0.627,0.872),P＜0.05].Receiver operating characteristic (ROC) curve confirmed that B-lines cut-off point 77[sensitivity of 100％,specificity of 64.3％ respectively,area under curve [AUC] =0.86,95％CI(0.724,0.945)] and 108[sensitivity of 90％,specificity of 88.6％ respectively,AUC=0.879,95％CI(0.747,0.957)] had an optimal power to discriminate mild (Warrick score＜8) and severe fibrosis (Warrick score＞15):Conclusion The data confirm that LUS is a useful technique to identify ILD in RA.In RA-ILD,B-lines correlate significantly with HRCT and are able to identify mild and severe degree of fibrosis.LUS is a promising non-invasive and non-ionizing strategy for screening RA-ILD.

ObjectiveTo investigate the efficacy of ovarian tissue cryopreservation and autologous transplantation in preserving fertility and ovarian endocrine function in patients with cervical cancer. MethodsA 26-year-old patient with stage ⅡA1 cervical cancer underwent ovarian tissue harvesting and cryopreservation during cancer surgery. Following complete remission of the cancer， autologous ovarian tissue transplantation was performed. Follow-up monitoring included assessment of menopausal symptoms， hormone levels， and follicular development. ResultsSix months after transplantation， follicle-stimulating hormone levels decreased to 6.60 U/L， and estradiol levels increased from ＜10.00 ng/L to 89.00 ng/L. At 10 months after transplantation， ultrasound monitoring confirmed follicular development and physiological ovulation in the transplanted ovarian tissue. By 15 months after transplantation， follicle-stimulating hormone levels remained stable at 7.24 U/L， and estradiol levels further increased to 368.00 ng/L. Over 2 years after transplantation， the patient successfully gave birth to a healthy baby through assisted reproductive technology. ConclusionThe restoration of endocrine and ovulation functions in the transplanted cryopreserved ovarian tissue， followed by successful pregnancy， demonstrates the clinical success of ovarian tissue transplantation.
