Tetrahydroxy stilbene glucoside alters neurogenesis and neuroinflammation to ameliorate radiation-associated cognitive disability via AMPK/Tet2.

Along with the extensive application of radiation in medical, military and other fields, human beings carry a greater risk of exposure to radiation environment that causes a range of physical injure, particularly to the brain in cognition. However, the radiation-associated cognitive disability is poorly understood and there is no effective prevention or long-term treatment. Here, we demonstrate that neurogenesis and neuroinflammation disorder are primarily involved in the pathophysiological basis of irradiation-induced cognitive decline. Furthermore, we discovered that tetrahydroxy stilbene glucoside (TSG), a natural active ingredient from Heshouwu that has been well known for its unique anti-aging effect as the Chinese herb, can be a promising mitigator to improve learning-memory ability by facilitating the neurogenesis in the proliferation and differentiation of the surviving neural progenitor cells via AMPK/Tet2, and attenuating the neuroinflammation in the microglial NLRP3 inflammasomes activation via AMPK in vivo. Additionally, TSG was also revealed to activate AMPK by molecular docking and kinase enzyme system assay in vitro. Taken together, our findings identify TSG, as the AMPK activator, prevents radiation-induced cognitive dysfunction by regulating neurogenesis and neuroinflammation via AMPK/Tet2 in rodents, and represents a very promising candidate for developing drugs that can be used for radiation-associated brain injury.

Preoperative Systemic Therapy Versus Upfront Surgery in HER2-Positive Breast Cancer in the Real World.

PURPOSE: To compare survival in different strategies, preoperative systemic treatment versus upfront surgery, in HER2-positive early breast cancer patients in the real world. METHODS: According to the actual upfront treatment, eligible patients from 2012 to 2015 were classified as preoperative systemic treatment or upfront surgery group prospectively. The primary endpoint is disease-free survival; the second endpoint is overall survival. All the outcomes were examined in the propensity score matching model and inverse probability of treatment weighting model. RESULTS: Included in the analysis were 1,067 patients (215 in the preoperative systemic treatment group, 852 in the upfront surgery group). In the propensity score matching model (matching at 1:1 ratio), the disease-free survival of the preoperative systemic treatment group was significantly higher than that of the upfront surgery group (hazard ratio, 0.572, 95%CI, 0.371-0.881, P, 0.012). In the inverse probability of treatment weighting model, there was no significant difference in disease-free survival between the two groups (hazard ratio, 0.946, 95%CI, 0.763-1.172, P, 0.609). For overall survival, there was no significant difference between the two groups. CONCLUSION: The HER2-positive patients who accepted preoperative systemic treatment had better disease-free survival than those who underwent upfront surgery by real-world statistic methods.

Automatic mental health identification method based on natural gait pattern.

Mental health has become a global problem, as over 300 million people worldwide suffer from depression and 200 million from anxiety disorders, which are ranked by the World Health Organization (WHO) as the first and sixth leading causes of disability, respectively. Due to the limited health resources, the traditional method of mental health diagnosis as one-to-one consultation is difficult to meet the needs of the large number of mental subhealth population. In this article, we propose a new method for mental health recognition that could identify potentially clinically significant symptoms of depression and anxiety based on daily gait. Eighty-eight participants were recruited, and their gaits were recorded by a digital camera. Then they were required to complete two rating scales, the Patient Health Questionnaire (PHQ-9) and the seven-item Generalized Anxiety Disorder Scale (GAD-7), to measure their depression and anxiety levels. Specifically, 18 key points of each individual's body trunk were captured from video, and both time-domain features and frequency-domain behavioral features were extracted for each key point. Lastly, machine-learning algorithms were utilized to build the mental health recognition models. Results showed that the proposed method is feasible and effective, with a correlation coefficient of depression (measured by PHQ-9) recognition above 0.5 and anxiety (measured by GAD-7) recognition above 0.4, achieving medium correlation. This new, low-cost, and convenient mental health recognition pattern could be applied in daily monitoring of mental health and large-scale preliminary screening of mental diseases.

Endoscopic thyroidectomy using gasless axillary approach for low-risk papillary thyroid carcinoma.

To evaluate the application of endoscopic thyroidectomy using gasless axillary approach (ET-GA) for low-risk papillary thyroid carcinoma (PTC). Patients with T1N0M0 Ⅰ PTC undergoing unilateral thyroid lobectomy with central neck dissection in Taizhou Cancer Hospital during January 2019 to June 2021 were enrolled in the study, including 35 cases treated with ET-GA (ET-GA group) and 35 cases treated with conventional open thyroidectomy (COT group). The surgical treatment effect, cosmetic effect and the effect on neck function were compared between two groups. Neck function was evaluated by neck pain score, neck injury index and dysphagia index. Cosmetic effect was evaluated by cosmetic effect satisfaction score. In the ET-GA group, all unilateral thyroid lobectomy with central neck dissection were successfully completed, and no case was converted to open surgery. The number of central lymph nodes dissected in the ET-GA was not statistically different from that in the COT group (>0.05), but the operation time was longer than that of the COT group (<0.01). In the ET-GA group, 2 cases (5.7%) had transient vocal cord paralysis and 1 case (2.9%) had postoperative bleeding. In the COT group, 1 case (2.9%) had transient vocal cord paralysis, no postoperative bleeding. There was no significant difference in the complication rate between two groups (>0.05). At and postoperatively, there was no significant difference in neck pain score and neck injury index between two groups (both >0.05); dysphagia index was lower in ET-GA group, but the difference was not statistically significant (>0.05). The cosmetic effect satisfaction score of ET-GA group was higher than that in the COT group at postoperatively (4.3±0.6 vs.1.0, <0.01). ET-GA has the same efficacy and safety as conventional open thyroidectomy in the treatment of low-risk PTC, and it improves the satisfaction of postoperative cosmetics.

Modular transitional nursing intervention improves pain-related self-management for cancer patients: Study protocol for a randomized controlled trial.

OBJECTIVE: To explore the effect of modular transitional nursing intervention on the improvement of self-management of the patients with cancer pain. METHOD: This study will be conducted from March 2021 to May 2022 at Affiliated Hospital of Beihua University. The experiment was granted through the Research Ethics Committee of Affiliated Hospital of Beihua University (4348-019). Eighty patients are analyzed in our study. The patients will be included if they are between 18 and 70 years old and are diagnosed with cancer, the pain intensity score on moderate level, the pain lasts for more than 3 days, and the patients who have signed the written informed consent. While the patients will be excluded if they have a documented history of drug or alcohol abuse, and patients with limited performance, and patients have a surgery in the past 3 days. The primary result mainly expresses as intergroup differences in self-management disorders (Barriers Questionnaire-II) associated with the cancer pain. And the secondary results include the quality of life (QOL) and pain intensity. All the analyses are implemented with SPSS for Windows Version 20.0. RESULTS: Table 1 will show the clinical outcomes between the 2 groups. CONCLUSION: A modular transitional nursing intervention appears to reduce pain in cancer patients.
