A sustainable training system for acupuncture-moxibustion and tuina professionals, integrating "medicine, industry, education and research" is established, under the main framework of the medicine-engineering interdiscipline, and with the consideration of the issues of medicine, the application of engineering technology, the thinking approaches of sciences, and the collaboration of business studies. It is the potential power to support the development of traditional medicine. Through analyzing the difficulties of the medicine-engineering interdiscipline of acupuncture specialty, and in association with the experiences of the early-stage development of the collaboration between medicine and engineering, the paper presents the cases of China's higher education reform and transformation under the background of "emerging medical education" so as to explore a replicable personnel training mode.

The deubiquitinase ZRANB1 is an E3 ubiquitin ligase for SLC7A11 and regulates ferroptotic resistance.

The dependency of cancer cells on iron increases their susceptibility to ferroptosis, thus providing new opportunities for patients with treatment-resistant tumors. However, we show that lipid peroxidation, a hallmark of ferroptosis, was found in various areas of patient samples, indicating the potential resistance of ferroptosis. Using whole deubiquitinases (DUBs) sgRNA screening, we found that loss of ZRANB1 confers cancer cell resistance to ferroptosis. Intriguingly, functional studies revealed that ZRANB1 ubiquitinates and represses SLC7A11 expression as an E3 ubiquitin ligase and that ZRANB1 inhibits glutathione (GSH) synthesis through SLC7A11 degradation, leading to elevated lipid peroxidation and ferroptosis. Deletion of the region (residues 463-584) abolishes the E3 activity of ZRANB1. Moreover, we show that ZRANB1 has lower expression in tumors, which is positively correlated with lipid peroxidation. Collectively, our results demonstrate the role of ZRANB1 in ferroptosis resistance and unveil mechanisms involving modulation of E3 ligase activity through an unconventional catalytic domain.

Antipyretic Mechanism Exploration of HuanglianShangqing Pill Based on Metabolomics and Network Pharmacology.

BACKGROUND AND OBJECTIVE: HuanglianShangqing pill (HLSQ), a well-known traditional Chinese medicine (TCM), has been used to treat fever in China for a long time. Our previous study had demonstrated that a total of 45 prototype components of HLSQ could be absorbed into the plasma of rats after intragastric administration. However, the detailed mechanisms related to the antipyretic effects of HLSQ were still unclear. METHODS: In the present work, urinary metabolomics coupled with network pharmacology were employed to evaluate the mechanisms of HLSQ in the treatment of fever compared with ibuprofen (IBU) and paracetamol (APAP). RESULTS: In pyrexia rats, a total of 11 potential metabolites and a disturbed TCA cycle were found. The metabolic regulation effects of HLSQ on fever rats were similar to APAP and could make the TCA cycle disorder return to normal by reducing citrate, ß-hydroxybutyrate, succinate. In addition, HLSQ could adjust the intestinal microbial disorder and inhibit inflammatory factors, including IL6, TNF, VEGFA, TP53, STAT3, etc. There were 40 components acting on fever targets in HLSQ; among them, luteolin, apigenin, ursolic acid, kaempferol, wogonin, daidzein, baicalein, emodin, berberine, and oroxylin A were the main active compounds of HLSQ in the treatment of fever. CONCLUSION: The antipyretic mechanisms of HLSQ are inhibition of inflammatory factors, action on the TCA cycle, and regulation of gut microbiota.

[An intelligent glass cupping device with closed-loop control].

As the living standard improves and population aging continues, the traditional cupping manipulations fail to meet the ever-growing demand for high-quality medical and health services. Aiming to address such shortcomings of traditional cupping manipulations as difficulty in achieving real-time temperature control, unsatisfactory negative pressure effect and inconve-nience to observe the internal situation, we have developed a glass cupping device with closed-loop control that could automatically integrate the acupoint-symptom analysis models. This device, composed of two cups, boasts high safety, good sealing and sound economic efficiency. The PT100 thermocouple probe and the pressure sensor equipped with P89C668 single chip microcomputer enable the multimodal integration of temperature and pressure, whose main parameters can be automatically displayed on the LED screen by the built-in data processing device. This glass cupping device with closed-loop control is an updated design for acupuncture and moxibustion based on multidisciplinary resources.

Curcumin prevents osteocyte apoptosis by inhibiting M1-type macrophage polarization in mice model of glucocorticoid-associated osteonecrosis of the femoral head.

Inflammation is a contributing factor in osteocyte apoptosis, which is strongly associated with the development of glucocorticoid-associated osteonecrosis of the femoral head (GA-ONFH). Curcumin is a naturally derived drug that regulates immunity and inhibits inflammation. This study aimed to examine the capacity of curcumin to prevent osteocyte apoptosis and GA-ONFH, while elucidating possible mechanisms of action. C57/BL6 female mice were divided into control, GA-ONFH, and curcumin-treated GA-ONFH groups. We determined the effect of curcumin on the polarization of RAW264.7 and the apoptosis of MLO-Y4 cells. We found that curcumin reduced the infiltration of M1-type macrophages in the femoral heads and alleviated systemic inflammation in GA-ONFH models. Additionally, curcumin decreased the apoptosis of osteocytes in the femoral heads and the ratio of GA-ONFH in mice. Further, in vitro curcumin intervention inhibited M1-type polarization via the Janus kinase1/2-signal transducer and activator of transcription protein1 (JAK1/2-STAT1) pathway. Taken together, this study demonstrates that curcumin is effective in preventing osteocyte apoptosis and the development of GA-ONFH in a mouse model. Curcumin prevents inflammatory-mediated apoptosis of osteocytes in part through inhibition of M1 polarization through the JAK1/2-STAT1 pathway. These findings provide novel insights as well as a potential preventive agent for GA-ONFH. This article is protected by copyright. All rights reserved.

Sleeve Gastrectomy Reversed Obesity-Induced Hypogonadism in a Rat Model by Regulating Inflammatory Responses in the Hypothalamus and Testis.

BACKGROUND: Obesity is a metabolic disease with a serious health burden in children and adults, and it induces a variety of conditions including subfecundity. Sleeve gastrectomy showed encouraging results in terms of weight loss and improve quality of life, and this study aimed to determine whether sleeve gastrectomy could reverse obesity-induced impaired fertility in male Sprague-Dawley rats. METHODS: After 16 weeks of a chow diet (CD) or a high-fat diet (HFD) challenge, rats on the HFD were given a sleeve gastrectomy or sham operation and then fed an HFD for another 8 weeks. Serum glucose, insulin, lipids, sex hormone, sperm quality, inflammatory profile of the testis, and hypothalamic Kiss1 expression in the three study groups were compared. RESULTS: Sleeve gastrectomy significantly decreased HFD-induced obesity and serum glucose and insulin levels. It also reversed the HFD-induced increase in teratozoospermia and decreases in sperm motility and progressive motility. Testicular morphological abnormalities were also improved after sleeve gastrectomy. Enzyme-linked immunosorbent assay showed that the expression of sex hormones increased after sleeve gastrectomy and that expression of inflammatory factors decreased. The HFD induced a hypothalamic inflammatory response that inhibited Kiss1 expression, which in turn mediated sex hormone expression. Sleeve gastrectomy treatment improved the hypothalamic response. CONCLUSIONS: The results consistently showed that sleeve gastrectomy reversed obesity-induced male fertility impairment by decreasing the inflammatory responses of the testis and hypothalamus.
