Objective To summarize the experience in transanal local excision (LE) for rectal cancer (RC). Methods The clinical data of 28 cases of RC treated by LE from 1988 to 1998 were analyzed retrospectively. Results In this series, five-year survival rate was 83.4?6.2%, and the local recurrence rate (LRR) was 17.8%. In well-differentiated carcinoma, 4 cases were convinced as local recurrence with a LRR of 17.4%(4/23); in moderately- differentiated carcinoma, one case with a LRR of 20.0%(1/5). The LRR in T 1 and T 2 group was 15.0% (3/20) and 25.0% (2/8) respectively. LRR was 16.7% (4/24) in patients with less than 1/3 bowel wall involved, LRR was 16.7%(4/24),whereas LRR was 25.0%(1/4) in more than 1/3 bowel wall involved group. In total bowel wall resection group the LRR was 16.7%(3/18) while in partial resection group was 20.0% (2/10). In patients with tumour size larger than 4 cm LRR was 22.2% (2/9), tumour size smaller than 4 cm LRR was 15.7% (3/19). Conclusion LE for RC might only be successfully performed in selected patients (T 1～T 2, N 0M 0, well or moderately-differentiated carcinoma,low RC within 6 cm from anal edge). The indications of transanal LE must be controlled strictly. Total excision of tumor and prevention of implantation of carcinoma are the main points in the prophylaxes of recurrence. Postoperative follow-up is needed in order to find local recurrence as early as possible.

Objective To explore a new way of physiological signal wireless measurement to popularize the physiological signal wireless measurement. Methods We added a UART-Wi-Fi module between the signal detecting module and the PC, the physiological signal measurement system transmitted the signal data collected by the single chip computer to the UART-Wi-Fi module through the serial interface RS-232C. Then the UART-Wi-Fi module sent the signal data out to the Wi-Fi wireless network. The PC received the signal data from the Wi-Fi wireless network and processed the signal data, then output the results. Result Through the UART-Wi-Fi module, the communication between PC and the signal detecting module was converted from wired communication into wireless communication successfully. Conclusion As a result of any computer can be used as a physiological signal receiving and processing terminal equipment, the use of the UART-Wi-Fi module can help achieve popularization of physiological signal wireless measurement.

The typical manifestations of primary aldosteronism (PA) are hypertension with or without hypokalemia, high aldosterone, and low renal level. However, PA with normal blood pressure is rare in clinical practice. This article reported the diagnosis and treatment of a patient with subclinical PA, admitted for "adrenal accidental tumor" with normal blood pressure and serum potassium. We summarized and analyzed the clinical characteristics and treatment strategies, in order to provide some reference for clinicians.

Objective To analyze the differential protein expression of three negative breast cancer tissue before and after menopause application of iTRAQ technology, to explore the effects of menopause on three negative breast cancer. Methods Selected premenopausal and postmenopausal women with 8 cases in each by negative pathological diagnosis, differential protein analysis on significant function, difference of protein pathway and difference of protein verify were analyzed by the application iTRAQ technology. Results (1﹚Differential protein interactome was relatively centralized premenopausal, and postmenopausal differences of protein was much, and the distribution of the dispersed. (2﹚In pre menopausal cancer tissue protein differences existed in 5 of the significant difference in differences approach; post-menopausal cancer tissue protein existsed in 15 significantly different pathways. (3﹚Tumor adjacent tissues compared with premenopausal had a total of 214 significant difference proteins, postmenopausal had a total of 360 significant differ-ence proteins. The upregul ated proteins in 81 kinds of premenopausal three negative breast cancer tissues, 133 down regμl ated proteins, postmenopausal up-regμl ated protein 157 types, down 203. Conclusion Using iTRAQ technology to found that the expression has a certain particμl arity differences in three negative breast cancer before and after menopause, indicate three negative breast cancer may have different pathogenesis in the different estrogen environment, may be a new target for treatment of TNBC.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Objective: To explore the key technique and outcome of transoral radiofrequency ablation microsurgery for early stage of glottic carcinoma with anterior commissure involvement (ACI). Methods: A retrospective analysis was conducted on 31 patients, who were diagnosed as early stage glottic carcinoma during January 2010 to March 2016 in ENT Department. According to whether the anterior commissure was involved or not, two groups were divided. There were eleven cases with ACI (stages T1a, T1b, and T2). Twenty cases without ACI (stages Tis, T1a, and T2). All the patients received transoral radiofrequency ablation microsurgery and followed up closely.Only one case received radiotheraphy after surgery. SPSS19.0 software was used to analyze data. Results: The follow-up time was 12-67 months, and the median follow-up time was 30 months. Nine among 11 cases with ACI obtained good oncologic outcomes, initial local recurrence was identified in 2/11 cases, including 2 cases of T2. Two cases ultimately required salvage total laryngectomy. Meanwhile, initial local recurrence was identified in 2/20 cases without ACI, including 1 case of T1a and 1 case of T2. One case underwent elective neck dissection, and another one received salvage total laryngectomy.Compared to the patients without ACI, it seemed that the cases with ACI always accomponied with a little higher initial local recurrence and lower overall laryngealpreservation, but the difference had no significance (P>0.05). Conclusions Transoral radiofrequency ablation microsurgery is an effective treatment for glottic carcinoma with ACI. Its advantages, such as more flexibility and deformability, make it more feasible to operate at the narrow space of anterior commissure assisted with laryngeal endoscopy.Good oncologic outcomes can be obtained by this technique with lower initial local recurrence as well as higher overall laryngeal preservation rate.
