OBJECTIVE: To observe the short-term results of Tos modified combined approach tympanoplasty (MCAT) in chronic suppurative otitis media. METHOD: This study is an observational study. The data of 26 patients (28 ears) underwent MCAT were collected. The surgical techniques, complications and preoperative and postoperative air-bone gap (ABG) were analyzed. RESULT: Of 28 ears, 26 ears (92.86%) get dry after surgery. 3 ears (10.71%)repaired tympanic membranes and reperforate postoperatively in which 2 minimal perforations were cured to close up patient treatment. One ear develops posterosuperior retraction pocket and one ear re-occurs cholesteatoma. One ear occurs blunting in the anterior sulcus and one ear has lateralization of the tympanic membrane. There are no hearing worsen and facial nerve palsy. For hearing, the postoperative pure tone threshold is better than preoperation (42.8 +/- 17.97 vs 47.49 +/- 18.01, P < 0.05) and postoperative ABG shrinks significantly (19.76 +/- 7. 49 vs 30.65 +/- 10.02, P < 0.01). CONCLUSION Based on the short-term results, Tos' MCAT can successfully dissect the diseases of tympanic cavity and mastoid and develop a stable aerating middle ear with a complete hearing conduction. It is safe and feasible in the treatment of chronic suppurative otitis media, as well as in the poor-pneumatic mastoid.

Objective:To observe the effect of local excision under ultrasonography with immediate mammoplasty in granulomatous lobular mastitis.Methods:Fifty-three patients with granulomatous lobular mastitis admitted from Jan 2017 to Jul 2020 were retrospectively analyzed. Combined with sonographic findings and clinical manifestations, patients were divided into four types: type Ⅰ, single mass; Type Ⅱ, single mass located in one quadrant with one or no skin lesion; Type Ⅲ, multi-quadrant involved with one or no skin lesion; Type Ⅳ, multiple abscesses with multiple lesions in the skin. Twenty-five patients underwent wide local excision (control group); Twenty-eight patients underwent local excision under ultrasonography with immediate mammoplasty (experiment group). Patients with erythema nodosum or in type Ⅳ were given antibiotics and corticosteroid therapy preoperatively for 1 week and postoperatively for 5 days. The others went straight to surgery.Results:All patients were followed up for 1 year. In the experiment group, 28 patients had primary wound healing, and 3 patients had poor wound healing after operation (all were of type Ⅳ). The control group had 6 cases of recurrence(were of type Ⅲ and type Ⅳ). There was significant difference of the recurrence rate between the two groups (0 vs. 24%, χ 2=6.033, P=0.014), and the aesthetic effect of local excision under ultrasonography with immediate mammoplasty was better than that of wide local excision(93% vs. 68%, χ 2=5.330, P=0.020). Conclusion:The recurrence rate of local excision under ultrasonography with immediate mammoplasty is low, and with a satisfactory cosmetic effect.

The lip color of a person is closely related to his or her health in the visual diagnosis of traditional Chinese medicine (TCM). The traditional method to judge the color of lips is through observing by a TCM doctor. The diagnosis result is affected not only by the doctor's knowledge and diagnosis experience, but also by the light, temperature and other environmental impacts. For these reasons, sometimes different doctors may make different judgement for the same lips. So it is urgently needed that an objective evaluation as reference for doctors can be obtained. A method based on support vector machine (SVM) that classifies lip color by computer automatically is presented in the present paper. Firstly, nine features of lip color in Hue, Saturation and Intensity (HSI) color space were extracted. Then, according to different combinations of these features five different experiments were conducted. By comparing the results of these experiments, it was discovered that the mean value is one of the most important features for the lip color. The overall effect of classification is better when the mean value and variance of HSI were chosen than other characteristics. In addition, experiments results demonstrated that the accuracy rate of classification is not improved when more features were adopted. The objective of the present paper is to select the appropriate characteristics and to combine them effectively to classify lip colors.

Tongue diagnosis is one of the essential methods of traditional Chinese medical diagnosis. The accuracy of tongue diagnosis can be improved by tongue characterization. Tongue area segmentation and homogeneous regions segmentation in tongue are important contents of preprocess of tongue image. An algorithm based on edge detection and Gradient vector flow (GVF) active contour for tongue area segmentation and another algorithm based on unsupervised segmentation of color-texture for homogeneous regions segmentation in tongue were presented. Totally about 1500 tongue images were collected. Results of tongue area segmentation achieved accuracy rate of 94.3% and results of homogeneous regions segmentation in tongue were approved by traditional Chinese medical experts. The experiments results show robustness of the algorithms. This work establishes solid foundation for feature selecting of Tongue diagnosis.

Objective To investigate the long-term efficacy and prognosis of concurrent chemoradiotherapy alone and concurrent chemoradiotherapy after neoadjuvant chemotherapy for stage ⅡB-ⅢB cervical squamous cell carcinoma. Methods A retrospective analysis was performed among 171 patients with stage ⅡB-ⅢBcervical squamous cell carcinoma who were admitted to our hospital and had complete follow-up data from February 1,2005 to October 31,2011. Results The median follow-up time was 66 months. There were no significant differences in the 3-or 5-year overall survival rates between the concurrent group and the neoadjuvant group(81.4% vs.75.9%,74.3% vs.67.2%,P=0.469).According to the subgroup analysis,there was no correlation between lymph node metastasis and survival curve(P=0.310,P=0.151).The univariate and Cox multivariate analyses showed that tumor size,lymph node metastasis,and concurrent chemotherapy method were independent prognostic factors for cervical cancer(P<0.05).For the patients with lymph node metastasis, the neoadjuvant group had a significantly higher pelvic local recurrence rate than the concurrent group (P=0.047),while there were no significant differences in mortality,distant metastasis,or long-term adverse reactions between the two groups(all P>0.05).For the patients without lymph node metastasis,the neoadjuvant group had a significantly higher incidence of grade 3-4 bone marrow suppression than the concurrent group (P=0.016), while there were no significant differences in mortality,local recurrence,distant metastasis,or long-term adverse reactions between the two groups (all P>0.05). Conclusions Concurrent chemoradiotherapy alone and concurrent chemoradiotherapy after neoadjuvant chemotherapy achieve similar treatment outcomes in patients with stage ⅡB-ⅢBcervical squamous cell carcinoma,no matter whether they have lymph node metastasis or not. Tumor size,lymph node metastasis,and concurrent chemotherapy method are independent prognostic factors.Neoadjuvant chemotherapy increases the risk of grade 3-4 marrow suppression during concurrent chemoradiotherapy,prolongs irradiation time,and increases the risk of local recurrence.
