In order to meet the need of autonomous control of patients with severe limb disorders, this paper designs a nursing bed control system based on motor imagery-brain computer interface (MI-BCI). In view of the low decoding performance of cross-subjects and the dynamic fluctuation of cognitive state in the existing MI-BCI technology, the neural network structure optimization and user interaction feedback enhancement are improved. Firstly, the optimized dual-branch graph convolution multi-scale neural network integrates dynamic graph convolution and multi-scale convolution. The average classification accuracy is higher than that of multi-scale attention temporal convolution network, Gram angle field combined with convolution long short term memory hybrid network, Transformer-based graph convolution network and other existing methods. Secondly, a dual visual feedback mechanism is constructed, in which electroencephalogram (EEG) topographic map feedback can improve the discrimination of spatial patterns, and attention state feedback can enhance the temporal stability of signals. Compared with the single EEG topographic map feedback and non-feedback system, the average classification accuracy of the proposed method is also greatly improved. Finally, in the four classification control task of nursing bed, the average control accuracy of the system is 90.84%, and the information transmission rate is 84.78 bits/min. In summary, this paper provides a reliable technical solution for improving the autonomous interaction ability of patients with severe limb disorders, which has important theoretical significance and application value.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Objectives:To investigate the effect of cardiac rehabilitation exercise guided by cardiopulmonary exercise test on cardiopulmonary function, cardiopulmonary endurance and activities of daily living in patients who had coronary heart disease after percutaneous coronary intervention (PCI).Methods:Seventy patients who had coronary heart disease after PCI treated in the Wenzhou Central Hospital from July 2022 to May 2023 were enrolled perspectively (3 cases eventually dropped out of the study), and they were divided into the control group (33 cases) and the rehabilitation group (34 cases) by random number table method. The control group was given conventional medication after PCI, while the rehabilitation group was additionally provided with exercise rehabilitation for 12 weeks on the basis of the control group. The patient′s cardiopulmonary function indicators, cardiopulmonary endurance indicators and ability of daily living(ADL) score of the two groups were compared before and after treatment.Results:After treatment for 12 weeks, the cardiopulmonary function indicators left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left atrial inner diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), forced expiratory volume in the first second (FEV 1), ratio of FEV 1 to forced expiratory volume (FVC) (FEV 1/FVC), maximum ventilation quantity (MVV) in the rehabilitation group were obviously improved compared with the control group: (102.8 ± 14.4) ml vs. (114.8 ± 20.4) ml, (39.9 ± 13.7) ml vs. (48.4 ± 16.9) ml, (37.1 ± 3.4) mm vs. (38.9 ± 3.6) mm, (50.3 ± 3.6) mm vs. (52.5 ± 4.7) mm, (64.0 ± 6.8)% vs. (59.6 ± 6.5)%, (2.39 ± 0.38) L vs. (2.10 ± 0.26) L, (77.7 ± 4.0)% vs. (73.8 ± 4.3)%, (101.6 ± 18.7) L/min vs. (89.6 ± 11.1) L/min, there were statistical differences ( P<0.05). After treatment for 12 weeks, the cardiopulmonary endurance indicators peak oxygen uptake (VO 2peak), peak oxygen uptake per kilogram of body weight (VO 2peak/kg), anaerobic threshold (AT), peak metabolic equivalent (METspeak), maximum working load (MWL) in the rehabilitation group were obviously improved compared with the control group: (1 441.8 ± 251.9) ml/min vs. (1 272.5 ± 207.0) ml/min, (20.7 ± 3.6) ml/(min·kg) vs. (18.2 ± 2.5) ml/(min·kg), (1 346.8 ± 201.3) ml/min vs. (1 075.4 ± 176.7) ml/min, (5.9 ± 1.1) Met vs. (5.2 ± 0.7) Met, (107.3 ± 29.1) Watt vs. (88.4 ± 17.8)Watt, there were statistical differences ( P<0.05). After treatment for 12 weeks, the ADL scores in the rehabilitation group was higher than that in the control group: (90.9 ± 8.1) scores vs. (85.6 ± 11.6) scores, there was statistical difference ( P<0.05). Conclusions:Carrying out cardiac rehabilitation exercise guided by cardiopulmonary exercise test can significantly enhance the cardiopulmonary function, cardiopulmonary endurance and self-care ability in patients who had accepted PCI for coronary heart disease.

Gegen Qinliantang is a representative prescription for dual releasing of exterior and interior and treating diarrhea with fever in the Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）. This prescription consists of Puerariae Lobatae Radix， Scutellariae Radix， Coptidis Rhizoma， and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle. The combination of the four herbal medicines has the ability to clear both the exterior and the interior， thereby halting diarrhea and clearing heat. According to the idea of treating different diseases with the same method， Gegen Qinliantang is used in clinical practice to treat type 2 diabetes mellitus （T2DM）， which demonstrates positive outcomes. T2DM is a chronic metabolic disease characterized by elevated blood glucose levels. The etiology and pathogenesis of T2DM are complex， mainly related to heredity， lifestyle， environment， diet and other factors. Clinical observations and experimental studies have shown that Gegen Qinliantang and its effective ingredients have significant effects of preventing and treating T2DM. Clinically， Gegen Qinliantang is often applied with modification， or in combination with Western drugs， demonstrating better therapeutic effects than Western drugs alone. Clinical practice has confirmed that Gegen Qinliantang can effectively alleviate the clinical symptoms， reduce the occurrence of complications， and alleviate gastrointestinal adverse reactions in T2DM patients. Experimental studies have demonstrated that Gegen Qinliantang can ameliorate insulin resistance and boost pancreatic function by regulating the insulin and inflammation signaling pathways， alleviating oxidative stress， and modulating gut microbiota to treat T2DM. Nevertheless， more thorough studies remain to be carried out to decipher the mechanism of Gegen Qinliantang in ameliorating insulin resistance in T2DM. To provide theoretical and data references for the subsequent in-depth research on the mechanism of Gegen Qinliantang in treating T2DM and the prevention and treatment of this disease， this article systematically reviews the clinical and experimental research progress of Gegen Qinliantang in ameliorating insulin resistance in T2DM.

In this study, a new in situ film of compound iodine oral spray was prepared by in situ gel technology, which was used to exert sustained-release effect for promoting the repair of oral ulcer wounds. Firstly, the formulation and process of the spray solution were optimized according to the spray state and film-forming time. The drug-liquid mixing ratio was evaluated by film-forming time and drug film adhesion. The drug content, stability, pH, and spraying effect of compound iodine oral spray prepared by the optimal formulation were investigated; and the physicochemical properties, including film formation time, solubility, hygroscopicity, moisture retention and in vitro release of drug film were evaluated. In addition, the biocompatibility of the film-forming materials and proliferation ability of drug film were investigated by cell experiment. Through the rabbit oral ulcer model, the in vivo film-forming and repair-promoting effects of compound iodine oral spray were evaluated. The results showed that the pH of liquid A and liquid B prepared were 6.21±0.02 and 6.42±0.03, respectively, which were in line with the normal pH range of oral mucosa; liquid A and liquid B had good stability and spray state; the iodine content in solution B was (1.96±0.01) mg/mL; the in situ membrane formation time in vitro and in the oral cavity were (118.3±3.6) s and (133.3±4.6) s, respectively; the 24-hour dissolution rate was (87.31±1.74)%, the moisture absorption rate was (124.17±7.13)%, and the moisture retention rate was (26.85±2.50)%; the iodine content in the oral spray was (47.42±0.39) mg/g, with good flexibility and adhesion, as well as some slow-release effect. In cell experiment, the film-forming materials showed good biocompatibility and growth promotion ability. The results of the rabbit oral ulcer experiment showed that the compound iodine oral spray could rapidly form a film in vivo and significantly promote the repair of oral ulcer. In conclusion, the compound iodine oral spray in situ film with a stable preparation process can effectively promote the repair of oral ulcer wounds, which provides a new idea for the research of novel oral mucosa formulations, with a good prospect of transfer.

Tetraacetyl phytosphingosine (TAPS) is an excellent raw material for natural skin care products. Its deacetylation leads to the production of phytosphingosine, which can be further used for synthesizing the moisturizing skin care product ceramide. For this reason, TAPS is widely used in the skin care oriented cosmetics industry. The unconventional yeast Wickerhamomyces ciferrii is the only known microorganism that can naturally secrete TAPS, and it has become the host for the industrial production of TAPS. This review firstly introduces the discovery, functions of TAPS, and the metabolic pathway for TAPS biosynthesis is further introduced. Subsequently, the strategies for increasing the TAPS yield of W. ciferrii, including haploid screening, mutagenesis breeding and metabolic engineering, are summarized. In addition, the prospects of TAPS biomanufacturing by W. ciferrii are discussed in light of the current progresses, challenges, and trends in this field. Finally, guidelines for engineering W. ciferrii cell factory using synthetic biology tools for TAPS production are also presented.
