ABSTRACT
Methods:The clinical data and follow-up results of 56 patients with refractory hyperthyroidism who underwent laparoscopy or open surgery in Affiliated Nanhua Hospital of University of South China from January 2019 to August 2020 were retrospectively analyzed.Results:Among the 56 patients, there were 6 men and 50 women. Thirty-six (64.3%) patients underwent endoscopic surgery and twenty (35.7%) patients underwent open surgery. The operation time was (132.0 ± 32.0) minutes. Intraoperative blood loss was (32.4 ± 27.8) mL. Postoperative parathyroid hormone level was (27.8 ± 18.3) ng/L. Forty-nine (87.5%) patients showed benign pathology results after surgery. After surgery, 14 (25.0%) patients had hypothyroidism, including 7 (12.5%) patients with hyperthyroidism combined with thyroid cancer. There were no patients with permanent hypothyroidism or recurrent laryngeal nerve paralysis. All patients had a good prognosis and satisfactory surgical results.Conclusion:With the update of preoperative preparation methods for hyperthyroidism, the increasing maturity of thyroid surgery technology, and the use of new energy instruments and technologies, surgical treatment is undoubtedly a good treatment method for patients with refractory hyperthyroidism or a suspected malignant tumor.Objevtives:To investigate the indications and clinical efficacy of surgical treatment in patients with refractory hyperthyroidism.
ABSTRACT
OBJECTIVES@#Neoadjuvant chemotherapy combined with radical surgery has become the treatment model for locally advanced rectal cancer. The purpose of this study was to evaluate the safety and efficacy of postoperative mFOLFOX6 regimen chemotherapy for locally resectable advanced rectal cancer.@*METHODS@#This was a prospective study. A total of 82 patients with locally advanced rectal cancer admitted to Affiliated Nanhua Hospital, University of South China from February 2015 to December 2017 were selected as the subjects. The patients received 4 courses of mFOLFOX6 chemotherapy and underwent surgery within 4-6 weeks after chemotherapy. The incidences of chemotherapy-related adverse reactions, postoperative complications, and clinical pathological reactions were analyzed.@*RESULTS@#In the period from mFOLFOX6 chemotherapy to preoperative, 82 patients with locally advanced rectal cancer was reported chemotherapy-related adverse reactions, including Grade 4 neutropenia (2.4%), catheter related infection (2.4%), and anorexia (2.4%), Grade 3 nausea (2.4%) and anorexia (2.4%), Grade 2 neutropenia (14.6%) and peripheral neuropathy (7.3%). Finally, 76 patients with locally advanced rectal cancer completed surgery, including 56 (73.7%) with anterior rectum resection, 16 (21.1%) with abdominal perineal resection, and 72 (94.7%) with pelvic nerve preservation. A total of 22 (28.9%) patients had surgical complications, including 8 (10.5%) with complications of Grade 3 or above. The complications with high incidence were intestinal obstruction, anastomotic leakage, and sepsis. Among the 76 patients who completed chemotherapy and surgery, T stage was decreased in 28 (36.8%) and N stage was decreased in 44 (57.9%); forty-two (55.3%) were in pathological Stage I, 20 (26.3%) in Stage IIA, 12 (15.8%) in Stage IIB, and 2 (2.6%) in Stage IIIA. Ten patients were suspected of tumor invasion of surrounding organs before chemotherapy, of which 4 patients did not need to extend the resection of surrounding organs after chemotherapy and achieved R0 resection of tumor; 2 in T@*CONCLUSIONS@#Preoperative mFOLFOX6 regimen chemotherapy for locally resectable advanced rectal cancer is a safe and feasible treatment strategy, and it is worthy of clinical application.

Objective To investigate the effect of high expression of protein tyrosine phosphatase SHP-1 on the tumor cell invasiveness and chemosensitivity of esophageal squamous cell carcinoma.Methods EC9706 ceils of esophageal squamous cell carcinoma were divided into three groups:the blank group was not given any treatment;the experimental group used SHP-1 mimic instantaneous vector to transfect cells for 24 h,and used 10 μmol/L cisplatin to treat EC9706 cells for 12 h;the control group selected 10 μmol/L cisplatin to treat EC9706 cells for 12 h.Cell proliferation was detected by using methyl thiazolyl tetrazolium (MTT) assay,and cell invasion was detected by using Transwell chamber.The expression of SHP-1 mRNA was detected by using fluorescence quantitative polymerase chain reaction.The expression level of SHP-1 protein was detected by using Western blot.Results The expression of SHP-1 mRNA in the experimental group (3.42t0.14) was higher than that in the control group and the blank group (1.09±0.13,0.42±0.24,F =9.143,P ＜ 0.05).Compared with the control group and the blank group,the cell growth inhibition rate and the apoptosis index in the experimental group were increased (both P ＜ 0.05),and the differences between any two groups were also statistically significant (all P ＜ 0.05).The cell invasion rate in the experimental group,the control group and the blank group was (6.5±1.3) ％,(18.5±2.5) ％ and (45.2±7.2) ％,respectively,and the difference was statistically significant (F =11.853,P ＜ 0.05).Conclusion High expression of SHP-1 can inhibit the invasion of esophageal squamous cell carcinoma,improve chemosensitivity,promote apoptosis and inhibit cell proliferation,which could lay a theoretical foundation for improving the efficacy of chemotherapy for esophageal squamous cell carcinoma.
