目的本研究旨在对RhD阳性个体中红细胞特异性表达的RHD基因不同转录本进行分析，并对选择性剪接发生的机制进行初步探讨。方法利用体外有核红细胞培养体系分离并培养RhD阳性个体的有核红细胞，使用逆转录聚合酶链反应（RT-PCR）技术对RhD阳性个体RHD基因外显子6至3’非编码区扩增后进行二代测序，分析mRNA转录本，并采用生物信息学方法分析RHD基因所有外显子5’及3’剪接位点的最大熵值。结果RHD基因的转录本以正常全长mRNA为主，除此之外还存在其他8种异常转录本。按照表达量从多到少，分别为外显子7缺失、外显子9缺失、外显子8和9缺失、外显子7、8和9缺失、外显子7和9缺失、外显子8和9缺失合并外显子7与10间插入一段170 bp的内含子7片段、全长mRNA但插入170 bp的内含子7片段和外显子9缺失但插入一170 bp的内含子7片段，其中最后3种为新转录本。生物信息学分析提示外显子7和外显子9异常剪接可能与其5’-剪接位点（5’-splice site，5’ss）或3’ss和剪接体结合能力下降有关，而内含子7片段异常表达于转录本中可能与其两端存在类似5’ss和3’ss剪接保守序列有关。结论RHD基因存在十分复杂的选择性剪接模式，使RhD阳性个体的RHD基因在mRNA水平上存在多种不同的剪接转录本。

Zinc telluride (ZnTe) nonlinear crystal, a commonly used electro-optical material, can be used to generate and detect Terahertz (THz) wave, and has been widely used in the fields of THz wave detection and imaging. However, the preparation of ZnTe crystal with high quality and large size still remains a challenge. In this paper, ZnTe single crystal rod with diameter of 40 mm and length of 140 mm was successfully prepared by the pressure assisted vertical Bridgman method. The crystal structure, crystalline quality, optical and electrical properties of ZnTe crystal were characterized and analyzed. The effects of annealing process of ZnTe crystal on the crystal's properties related to Te inclusions were investigated. According to the research results, after annealed at 850 ℃ for 200 h under Zn atmosphere, the transmittance of the crystal in the visiblenear infrared wave band reaches up to 62%, the resistivity of the crystal is 104 Ω·cm, and the absorption coefficient is from 5 cm-1 to 15 cm-1 at the range from 0. 2 THz to 2 THz. The results provide a valuable reference for the preparation of highquality ZnTe crystal. [ABSTRACT FROM AUTHOR]

At the 30th anniversary of their dialogue relations, China and ASEAN agreed to upgrade their relationship to a comprehensive strategic partnership for peace, security, prosperity and sustainable development. China-ASEAN relations have been a cornerstone for the post-Cold War peace and prosperity in East Asia and the core for Asian regionalism. Under the three guiding principles of creating strategic opportunities, constructing developmental peace, and adhering to ASEAN centrality, their relationship has been dynamic and substantive. As the China-ASEAN relationship becomes increasingly asymmetric and China-US interaction in the region becomes more competitive in the years after the 2008 global financial crisis, ASEAN has developed mixed feelings and perceptions about China’s growing power and influence in the area. In particular, ASEAN has felt anxious about the impact of intensifying geopolitical competition on the regional cooperation process and ASEAN centrality. Since the outbreak of COVID-19, ASEAN has realized the urgency of strengthening its own cohesiveness, promoting major-power cooperation, and addressing non-traditional security threats such as infectious diseases to achieve post-pandemic economic recovery and sustainable growth. To build a future-oriented comprehensive strategic partnership, China should exercise restraint, shoulder responsibility, and work with ASEAN as equal partners to create a consensus-based regional order.

[Objectives] This study was conducted to explore the effect of fruit load per eluster on fruit quality, aroma components and relevant gene expression levels in 'Shine Museat' grape. [Methods] Taking the 'Shine Museat' as experimental material, berry thinning was conducted to leave 40 ( \M), 60( 1.60), 80( 1.80) berry numben ; per cluster at one week after flowering. The aroma eomponent and contents at different development stages i in grape were thoroughly: determined by GC-MS, and the expression of relevant genes in the grape at different development stages were determined by qRT-PCR.[Results]The effect of different fruit loads on the appearanee of grape fruit was obvious. 1-40 treatment was superior uill i graceful shape, full fruit and uniform color; 1-60 treatment ineluded smaller berries and sparse cluster ; 1.80 treatment reac hed ripe inconsistency and mixed with different size fruit. ITie soluble solid contents of 1.40 treatment were higr ier, and titrate acid contents were lowest with significant difference. At the maturity stage, C6 compound eontents of 1.60 treatment were higher, but for the total terpene contents, L40 treatment was the highest, and especially for linalool and geraniol. In addition, the terpene compounds of 1.40 treatment dropped more slowly, and several trace terpcnes such as cis-lina]oloxide, citronello] disappeared later. The transcriptional analysis of the relative genes revealed that alcoholdehy drogenase gene( VvADH) was mainly responsible for alcohols accumulation. The expression of deoxyxylulose 5-phosphate synthase gene(VvDXS) was significantly affected by the treatment of different fruit loads, and correlated with the total content of terpenes. Overall the expression of VvDXS in L40 treatment was higher th. an others. [Conclusions] The treatment of 40 berry numbers was conductive to the accumulation and preservation of aroma compounds at the late stage of fruit development, and could significantly improve the appearance quality of the fruit.

Objective To explore the long-term therapeutic effects of co-transplantation of Sprague-Dawley (SD) rats islets and bone marrow mesenchymal stem cells (BMSCs) to treat type 1 diabetes mellitus (T1DM). Methods BMSCs were isolated from 1 week of age of 4 healthy male SD rats while islets were isolated from 6-8 weeks of age of 3 healthy male SD rats BMSCs and islets were both cultured with 1640 nutrient medium in either separately or together in vitro. The cell morphology, levels of insulin and C-peptide in each group were examined at the 1st, 3rd, and 7th day after culture. T1DM model (male SD rats, body weight 180-200 g) was established by administration of 1% streptozotocin (STZ) citrate buffer (60 mg/kg) through intraperitoneal injection. T1DM model rats were randomly divided into 4 groups: model group, BMSCs transplantation group, islets transplantation group, and co-transplantation group (15 rats each group) for the cell transplantation test in vivo. The fasting glucose, body weight, insulin, C-peptide, total bilirubin (TBIL), aspartate transaminase (AST) and alanine aminotransferase (ALT) of each group were examined at the 1st, 3rd, 7th, 14th, and 30th day after transplantation. Data between multigroups were analyzed by ANOVA, and data between two groups were analyzed by t test. Results Compared to islets transplantation group, blood glucose in co-transplantation group's was lower (t=11.44-28.02, P<0.05), and insulin (t=10.03-6.86, P<0.05) and C-peptide (t=1.47-2.59, P<0.05). However, the TBIL (t=7.67-6.39, P<0.05), AST (t=12.00-8.89, P<0.05), and ALT (t=8.08-10.40, P<0.05) in co-transplantation group were lower than those in islets transplantation group. The expression intensity of insulin was stronger in co-transplantation group than islets transplantation group. The differences of above indexes between model group and BMSCs group had no statistical significance (all P>0.05). Conclusion Compared with islets transplantation alone, islets and BMSCs co-transplantation have better therapeutic effects on T1DM. [ABSTRACT FROM AUTHOR]
