Directed Evolution of Escherichia coli Nissle 1917 to Utilize Allulose as Sole Carbon Source.

Sugar substitutes are popular due to their akin taste and low calories. However, excessive use of aspartame and erythritol can have varying effects. While D-allulose is presently deemed a secure alternative to sugar, its excessive consumption is not devoid of cellular stress implications.

[Survival Analysis of 76 Cases of Head and Neck Adenoid Cystic Carcinoma with Lung Metastasis].

Background: Adenoid cystic carcinoma (ACC) of the head and neck often develops lung metastasis. At present, there are not many research reports on ACC lung metastasis, little is known about its exact clinical features and treatment results, and there is no consensus on the best treatment strategy. This study explored the effective treatment strategies, clinical outcomes and long-term prognosis of head and neck ACC lung metastases.

[Analysis of Influencing Factors for Postoperative Venous Thromboembolism of Thymic Malignancies].

Background: The previous study has indicated that the incidence of venous thromboembolism (VTE) after thoracic surgery is high. The purpose of this study was to analyze the incidence and risk factors of postoperative VTE in thymic malignancy patients.

Methods: This was a single-center study.

Placing covered self-expanding metal stents by suspension laryngoscope in benign tracheal stenosis.

Background: Tracheobronchial stent placement for malignant airway strictures has been proved to improve respiratory function, but experience for benign tracheobronchial stenoses is limited. The purpose of our study is to investigate the efficacy of covered expandable metallic stents, inserted through a suspension laryngoscope, treating tracheal stenosis following intubation or tracheostomy.

Methods: From 2010 to 2018, 67 adult patients with the benign tracheal stenosis, underwent stent placement, using a suspension laryngoscope.

Surgical feasibility and long-term outcome of superior vena cava replacement for advanced thymoma in patients undergoing preoperative chemotherapy or chemoradiotherapy.

Background: The aim of this study was to investigate the long-term outcome of superior vena cava (SVC) replacement after chemotherapy or chemoradiotherapy for advanced thymoma.

Methods: The medical information of patients with advanced thymoma who underwent thymoma resection and SVC replacement in Beijing Tongren Hospital from 2002 to 2017 were reviewed. We compared surgical outcomes, postoperative complications and long-term prognosis in the chemoradiotherapy + surgery group (CRT + surgery group, 19 cases) and the surgery group (26 cases).

Venous thromboembolism after adult thymus or thymic tumor resection: A single-center experience.

Background: Venous thromboembolism (VTE) is a common postoperative complication. Previous studies have shown that the VTE incidence after major thoracic surgery is high. However, there have been no exclusive data after thymectomy thus far.

Evaluating the effectiveness of chemotherapy for thymic epithelial tumors using the CD-DST method.

Background: Thymic epithelial tumors (TET) are frequently eligible for curative-intent surgical resection. For locally advanced TETs, chemotherapy has been used to both reduce the tumor burden and achieve prolonged disease control. However, effective therapy for this disease largely remains to be determined.

Identification of differentially expressed genes affecting hair and cashmere growth in the Laiwu black goat by microarray.

Goats are an important source of fibers. In the present study microarray technology was used to investigate the potential genes primarily involved in hair and cashmere growth in the Laiwu black goat. A total of 655 genes differentially expressed in body (hair‑growing) and groin (hairless) skin were identified, and their potential association with hair and cashmere growth was analyzed.

[Comparison of cutaneous temperature at 12 Jing-well points regions of bilateral yin- and yang-meridians in healthy volunteers].

Objective: To observe differences of cutaneous temperature of the 12 Jing-well points regions of the yin-meridians and yang-meridians, and on the upper and lower limbs so as to provide a reference for clinical diagnosis.

Methods: A total of 26 healthy young volunteers (15 men and 11 women, 23 to 31 years in age) participated in the present study. The skin temperature of the 12 Jing-well points [Shaoshang (LU 11), Sahngyang (LI 1), Yinbai (SP 1), Lidui(ST45), Shaochong (HT9), Shaoze (SI 1), Yongquan (KI 1), Zhiyin (BL 67), Zhongchong (PC 9), Guanchong(SJ 1), Dadun (LR 1) and Qiaoyin (GB 44)] at night (19:00-21:00) was detected under a room temperature of (20 +/- 2) degrees C and humidity of 65%-75% by using an infrared thermometer.
