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.

Organ transplantation has emerged as a therapeutic modality for children with end-stage organ failure. With advancements in surgical techniques, organ preservation methods, and immunosuppressive therapies, both the success rate of transplantation and the long-term quality of life of recipients have continued to improve. Initially applied primarily in cardiothoracic transplantation, extracorporeal membrane oxygenation (ECMO) has gradually expanded its role in pediatric organ transplant recipients to include perioperative support for cardiopulmonary complications in abdominal organ transplants such as liver and kidney, as well as in the maintenance of deceased donors. With ongoing refinements in ECMO technology and equipment, its significance in supporting children with end-stage organ failure has become increasingly prominent, offering renewed hope and survival for a growing number of pediatric patients with organ failure.

Glutamate receptor-like (GLR) is an important class of Ca²⁺ channel proteins, playing important roles in plant growth and development as well as in response to biotic and abiotic stresses. In this paper, we performed genome-wide identification of banana GLR gene family based on banana genomic data. Moreover, we analyzed the basic physicochemical properties, gene structure, conserved motifs, promoter cis-acting elements, evolutionary relationships, and used real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) to verify the expression patterns of some GLR family members under low temperature of 4 ℃ and different hormone treatments. The results showed that there were 19 MaGLR family members in Musa acuminata, 16 MbGLR family members in Musa balbisiana and 14 MiGLR family members in Musa itinerans. Most of the members were stable proteins and had signal peptides, all of them had 3-6 transmembrane structures. Prediction of subcellular localization indicated that all of them were localized on the plasma membrane and irregularly distributed on the chromosome. Phylogenetic analysis revealed that banana GLRs could be divided into 3 subclades. The results of promoter cis-acting elements and transcription factor binding site prediction showed that there were multiple hormone- and stress-related response elements and 18 TFBS in banana GLR. RT-qPCR analysis showed that MaGLR1.1 and MaGLR3.5 responded positively to low temperature stress and were significantly expressed in abscisic acid/methyl jasmonate treatments. In conclusion, the results of this study suggest that GLR, a highly conserved family of ion channels, may play an important role in the growth and development process and stress resistance of banana.

Objective To observe the clinical efficacy of TCM periodic therapy combined with estradiol progesterone tablets (Diane-35) in the treatment for polycystic ovary syndrome (PCOS), and its effects on serum sex hormone, glucose and lipid metabolism.Methods Totally 74 patients with PCOS were randomly divided into Western medicine (WM) group and Chinese and Western medicine (CWM) group, 37 cases in each group. WM group was given Diane-35, while CWM group was treated with TCM periodic therapy additionally, for three courses, 28 d of one course. Clinical symptoms, sex hormones and glucose and lipid metabolism of two groups were observed before and after treatment and withdrawal treatment for 3 months.Results Two patients in each group were lost to follow-up. Markedly effective rate and total efficiency rate of CWM group were better than WM group (P<0.05). After treatment, symptom integrals of CWM group decreased significantly (P<0.01). Serum E2 increased (P<0.01), while LH, T and LH/FSH decreased in two groups (P<0.01). After treatment and withdrawal treatment for 3 months, improvement of clinical symptoms and sex hormone levels in CWM group was superior to CM group (P<0.01), FPG, FINS, TG, TC and BMI of CWM group decreased in CWM group (P<0.05), and lower than that of CM group (P<0.05,P<0.01). Adverse reaction rates of WM group and CWM group were 17.1% and 5.71% (P<0.05).Conclusion Efficacy of TCM periodic therapy combined with Diane-35 in treatment of PCOS is significant, which can obviously improve patients’ clinical symptoms, and regulate hormone and lipid metabolism disorders, with fewer adverse reactions.

The host inflammatory reaction is a normal response to injury and the presence of foreign substances. Macrophage is one of the principal cell types in controlling host inflammatory and immune processes; hence, its response to biomaterials has a direct impact on biocompatibility and stability of biomaterials in vivo. This review describes the interaction of macrophages with tissue engineering related biomaterials. The bulk physicochemical structure and surface performance of biomaterials could be designed to control macrophages behaviors (i. e. adhesion, activation, fusion, apoptosis) and host responses, resulting in improving biocompatibility of biomaterials.

OBJECTIVE: To investigate the relationship between single nucleotide polymorphism of gene and ischemic stroke and search for predisposing genes of ischemic stroke.DATA SOURCES: The Medline database was searched for articles of gene polymorphism of fibrinogen and ischemic stroke published from 1980 to 2005 with the key words of "stroke, plasma fibrinogen, polymorphism"in English. Meanwhile, Vip Information Database was also searched for literatures of gene polymorphism of fibrinogen and schemic stroke published between 1995 and 2005 with the key terms of "ischemic stroke, fibrinogen,gene polymorphism" in Chinese. Full-texts were gotten by correspondence with the authors.STUDY SELECTION: Included literatures were only case control study literatures. Literatures of contrast study, experience summary, individual case and so on were excluded.DATA EXTRACTION: Totally 50 articles of gene polymorphism of fibrinogen and ischemic stroke were retrieved. Twenty articles were accorded with inclusive criteria, and thirty articles were excluded.DATA SYNTHESIS: Level of plasma fibrinogen was co-affected by heredity and environment. Gene polymorphism of fibrinogen has important regulatory effects on the level of plasma fibrinogen. The fibrinogen accelerates thrombotic formation. As a result, the incidence rate of ischemic stroke increased by participating atherosclerosis, helping thrombocytic aggregation and changing the status of hemorheology. But definite mechanism and molecular function of gene polymorphism of fibrinogen deserved further research.CONCLUSION: The relationship between single nucleotide polymorphism of fibrinogen and ischemic stroke remains obscure. It also needs further study.
