The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

Abstract: Objective To investigate the nutritional status of patients with pulmonary tuberculosis and its effects on conventional anti-tuberculosis treatment, so as to provide a basis for improving the efficacy of conventional treatment of pulmonary tuberculosis. Methods The relevant data of 168 patients with pulmonary tuberculosis admitted to Suining Central Hospital from April 2020 to April 2022 were retrospectively analyzed. Nutritional status of the patients before treatment was investigated using the Mini Nutritional Assessment (MNA) score, and the influencing factors of nutritional status before treatment were analyzed. Therapeutic effects of anti-tuberculosis drugs in the non-nutritional risk group and the nutritional risk group were comparatively analyzed. Results Among the 168 patients, 64 were assessed as having good nutritional status before treatment, 59 had the risk of malnutrition and 45 were malnourished according to the MNA score. Univariate analysis and linear regression analysis showed that age, underlying diseases, and clinical symptoms were factors affecting the MNA score before treatment (t=3.173, 3.718, 2.018, P all<0.05); whereas gender and education level were not factors affecting MNA score before treatment (t=0.065, 0.059, P all>0.05). According to the MNA score before treatment, the patients were dividedinto a non-nutritional risk group (MNA score > 23.5) and a nutritional risk group (MNA score ≤23.5). The negative conversion rate of sputum bacteria, effective rate of focal absorption in the non-nutritional risk group were 92.19% (59/64)and90.63% (58/64) , respectively, which were significantly higher than corresponding 79.85% (82/104)and76.92% (80/104) in the nutritional risk group. The drug resistance rate, adverse reaction rate, and average treatment cost of the no nutritional risk group and nutritional risk group were 7.81% (5/64) and 21.15% (12/104), 15.63% (10/64) and 31.73% (33/104), (0.62±0.13) million yuan and (0.89±0.26) million yuan, respectively, with significant differences (χ2=5.228, 5.071, 7.685, 5.396, 7.728, P all<0.05). Conclusions Patients with pulmonary tuberculosis exhibit poor nutritional status before treatment. The patients’nutritional status is easily affected by age, underlying diseases, and clinical symptoms, thereby affecting the effect of anti-tuberculosis treatment. Therefore, early nutritional intervention for tuberculosis patients should be recommended in order to prevent malnutrition and enhance the effectiveness of anti-tuberculosis treatment.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.
