Madelung's disease is more common in male patients who drink alcohol. It can affect many parts of the body, but rarely affects scrotum. A case of Madelung's disease involving the scrotum was reported. The scrotum tumor was removed by operation and good results were obtained. No recurrence was found in the follow-up of 14 months. Surgical resection could be an effective treatment for this disease.

Objective:To explore the application effects of standardized patient (SP) and breast visual palpation simulation system on clinical probation of breast surgery for medical students.Methods:A total of 110 students were randomly divided into experimental group and control group, and each group was further divided into 5 subgroups. In the experimental group, SP scripts of five common diseases in breast surgery department were designed according to the syllabus before probation, and the teachers were trained. During the probation, we first talked about the characteristics of disease diagnosis and treatment, and then the five subgroups collected the history of the disease according to the SP of different diseases mentioned above, and checked the corresponding lesions on the breast visual palpation simulation system. In the physical examination, SP responded to the students' questions. The control group also talked about the above-mentioned five diseases during the probation, and then the five subgroups carried out history collection and physical examination for specific patients in the hospital. Finally, the teaching effects were analyzed through medical record writing, theoretical examination, physical examination and student evaluation. SPSS 26.0 was used for chi-square test (or Fisher exact test) and Mann-Whitney U test. Results:There was no significant difference in the theoretical examination between the two groups. It was demonstrated that the correct rate of experimental group was significantly higher than that of the control group in medical history collection, especially in the main symptoms, incentives, aggravation and remission factors, accompanying and differential symptoms and so on. And the positive results of breast, nipple and axillary lymph node palpation in the experimental group were significantly higher than those in the control group through the physical examination operation of breast visual palpation simulation system. The analysis of students' evaluation showed that the teaching efficiency of the experimental group increased, and the students' satisfaction was improved (satisfaction rate: 92.73% vs. 76.36%).Conclusion:The application of SP and breast visual palpation simulation system in breast surgery probation teaching can not only protect the privacy of clinical patients, but also improve the teaching effects, which can be popularized in the clinical teaching of breast surgery.

Objective:To compare the therapeutic effects of microdissection tungsten needle and high-frequency electrosurgical generator on open thyroid surgery.Methods:95 patients who underwent open thyroid surgery from Jan. 2017 to Dec. 2017 in the Department of Breast and Thyroid Surgery, Daping Hospital of Army Military Medical University were divided into microdissection tungsten needle group ( n=50) and high-frequency electrosurgical generator group ( n=45) according to different methods. The operation time, intraoperative blood loss, postoperative drainage volume, postoperative complication rate and recurrence and metastasis rate of the two groups were compared. Results:There were no significant differences in operation time (79.3±14.7 vs 73.7±13.9, t=1.914, P=0.059) , intraoperative blood loss (31.8±9.7 vs 30.3±10.6, t=0.702, P=0.484) and postoperative drainage volume (67.3±13.0 vs 71.3±10.8, t=-1.650, P=0.102) between the two groups ( P>0.05) . There were significant differences between the two groups in temporary recurrent laryngeal nerve (RLN) injury (2% vs 17.8%,χ 2=5.518, P=0.023) and temporary hypoparathyroidism (18% vs 44%,χ 2=7.810, P=0.005) , and the results of the microdissection tungsten needle group were better than high-frequency electrosurgical generator group ( P<0.05) . There were no permanent RLN and permanent hypoparathyroidism in the two groups. There were no recurrence and metastasis during the follow-up period. Conclusions:The microdissection tungsten needle is superior to the high-frequency electrosurgical generator in the protection of RLN and parathyroid gland in open thyroid surgery, which is worthy of promotion in clinical application.

Objective:To summarize the experience of diagnosis and treatment of primary thyroid lymphoma (PTL) and improve the level of diagnosis and treatment.Methods:The clinical and pathological data of 19 patients with PTL admitted to the Department of Breast and Thyroid Surgery, Daping Hospital, Army Medical University From Mar. 2000 to Jul. 2019 were retrospectively reviewed.Results:among the 19 PTL patients, 4 were male and 15 were female, with an average age of 69 years (51-88 years) . 15 cases showed rapid enlargement of neck mass, 9 cases with swallowing obstruction, 7 cases with hoarseness and 5 cases with dyspnea. 13 cases were diagnosed by intervention, the other 6 cases were diagnosed by biopsy. There were 1 case of Hodgkin’s lymphoma and 18 cases of non Hodgkin’s lymphoma, including 13 cases of diffuse large B cell lymphoma and 4 cases of mucosa associated lymphoid tissue lymphoma. 12 cases received chemotherapy and 1 case received radiotherapy. The median follow-up period was 28 months (0-88 months) , 5 cases were lost, 6 cases died, 3 cases died of recurrence and spread of lymphoma, 3 cases died of others.Conclusions:PTL is more likely to occur in the elderly women, which is characterized by sudden enlargement of cervical mass and its related compression symptoms. The diagnosis can be confirmed by coarse needle biopsy or surgical intervention. PTL needs comprehensive treatment including surgery, chemotherapy and targeted treatment.

Objective:To discuss the surgical approach and the clinical effect of laparoscopic enucleation for hepatic hemangioma(HH).Methods:Forty HH patients admitted in the Third Affiliated Hospital of Soochow University between Aug 2018 and Dec 2019 were analyzed. The technical knowhow involved is to make a good explosure of the pseudocapsular HH from underneath. Herewith a process of HH enucleatoin started.Results:All the 40 patients undergone total laparoscopic hepatectomy successfully.The operative time was (90.3±32.3)min, the intraoperative blood loss was (50±500)ml, the time of hepatic block was (12.5±35.4) min. The volume of postoperative drainage was 10-150 ml on the first postoperative day, and was gradually reduced to <30 ml on the third day after the operation. All patients were up and about from post-op day 2. The length of stay after operation was (5.5±2.7)d. There were significant differences in ALT、AST、TBIL and prealbumin in 1 and 3 days after surgery (seperately, t=-5.481, -4.182, -2.235, 9.722, all P<0.05), before back to normal on day 7 (seperately t=0.167, -1.392, 1.000, -2.531, all P>0.05). Liver function recovered to normal in 7 days after surgery. Conclusion:New approach breaks the traditional stripping method and makes the procedure simple, safe, lessly disturb the liver function.

Purpose: Real-time detection and intervention can be used as potential measures to markedly decrease breast cancer mortality. Assessment of circulating tumor DNA (ctDNA) may offer great benefits for the management of breast cancer over time. However, the use of ctDNA to predict the effectiveness of neoadjuvant treatment and recurrence of breast cancer has rarely been studied. Methods: We prospectively recruited 31 breast cancer patients with 4 subtypes. Three time points were set in this study, including before any therapy (C1), during surgery (T), and six months after surgery (C2). We collected peripheral blood samples from all 31 patients at C1, tumor tissue from all 31 patients at T, and peripheral blood samples from 25 patients at C2. Targeted 727-gene panel sequencing was performed on ctDNA from all blood samples and tissue DNA from all tissue samples. Somatic mutations were detected and analyzed using a reference standard pipeline. Statistical analysis was performed to identify possible associations between ctDNA profiles and clinical outcomes. Results: In total, we detected 159, 271, and 70 somatic mutations in 30 C1 samples, 31 T samples, and 12 C2 samples, respectively. We identified specific genes, such as PIK3CA, TP53, and KMT2C, which were highly mutated in the tissue samples. Furthermore, mutated KMT2C observed in ctDNA of the C2 samples may be an indicator of breast cancer recurrence. Conclusion Our study highlights the potential of ctDNA analysis at different timepoints for assessing tumor progression and treatment effectiveness, as well as prediction of breast cancer recurrence.

Male breast cancer (MBC) is rare and accounts for approximately 1% of all breast cancer cases worldwide. Previous studies have suggested that several factors significantly increase the risk of MBC. Prolactinoma has the highest incidence rate among patients with functional pituitary tumors. However, whether prolactinoma is involved in the onset and progression of breast cancer remains unclear. To date, there are only five case reports globally on MBC with concurrent prolactinoma. We hereby describe the first case of MBC with prolactinoma in China. We also explored the patient's genetic profile using whole exome sequencing. Our findings may help advance our understanding of the molecular pathogenesis of MBC. Further molecular analyses of such cases are warranted to improve auxiliary molecular diagnostic methods and targeted therapy for MBC.

Objective: To evaluate the clinical significance of C-reactive protein/albumin ratio in predicting the postoperative prognosis of pancreatic cancer patients. Methods: The clinical date of 97 patients with resectable pancreatic cancers who treated at Department of Hepatobiliary and Pancreatic Surgery, the third Affiliated Hospital of Soochow University from January 2005 to December 2015 were analyzed retrospectively. The cut-off value of CRP/Alb ratio was determined by the receiver operating characteristic(ROC) curve. According to the CRP/Alb ratio, patients were respectively divided into two groups: the high group(CRP/Alb ratio≥0.109) and the low group(CRP/Alb<0.109). The relationships between CRP/Alb ratio and clinical characteristics were analyzed by χ² test. Median survival and 1-year overall survival rate(OS) was calculated by Kaplan-Meier method.The risk factors of patients with poor prognosis were analyzed by univariate and multivariate Cox regression analysis model. Results: Tumor TNM stage(χ²=4.280, P=0.039) and differentiation(χ²=6.635, P=0.010) had significant relationship with CRP/Alb ratio. The median survival of higher CRP/Alb ratio group and lower CRP/Alb ratio group was 15 months and 23 months respectively. Compared with lower CRP/Alb ratio group, the 1-year OS of higher CRP/Alb ratio group decreased remarkablely, and the difference was statistically(χ²=10.207, P=0.001). Moreover, median survival and OS were decreased in patients with advanced age(≥65 years old: χ² =5.338, P=0.021), high TNM stage(ⅡB-Ⅲ: χ² =10.529, P=0.001), poor tumor differentiation(χ²=5.380, P=0.020), vascular invasion(χ² =7.856, P=0.005) and positive surgical margin(χ²=9.059, P=0.003). A high CRP/Alb ratio was identified as an independent risk factor of poor prognosis for patients with pancreatic cancer(HR=1.832, 95% CI: 1.067-3.144, P=0.028). Besides, old age(HR=1.684, P=0.014), high TNM stage(HR=1.666, P=0.031), vascular invasion(HR=1.834, P=0.024) and positive surgical margin(HR=2.205, P=0.023) were also included. Conclusion Preoperative CRP/Alb ratio can be an important clinical factor for assessing the prognosis of patients with resectable pancreatic cancers, and high CRP/Alb ratio suggests poor prognosis.
