YABBY proteins are important transcription factors that regulate morphogenesis and organ development in plants. In order to study the YABBY of strawberry, bioinformatic technique were used to identify the YABBY gene families in Fragaria vesca (diploid) and Fragaria×ananassa (octoploid), and then analyze the sequence characters, phylogeny and collinearity of the family members. The RNA-seq data and the quantitative reverse transcription-polymerase chain reaction (qRT-PCR) technique were used to assay the expression patterns of the family members. A green fluorescent protein (GFP) was fused with FvYABBYs and transiently expressed in tobacco leaf cells for the subcellular localization. As the results, six FvYABBY genes and 26 FxaYABBY genes were identified from F. vesca and F.×ananassa, respectively. The FvYABBY genes were grouped into five clades, and five family members were orthologous with AtYABBY genes of Arabidopsis. In F. vesca, all of the FvYABBYs were basically not expressed not expressed in root and receptacle, while FvYABBY1, FvYABBY2, FvYABBY5 and FvYABBY6 were highly expressed in leaf, shoot, flower and achene. In F.×ananassa, FxaYABBY1, FxaYABBY2, FxaYABBY5 and FxaYABBY6 were expressed in achene, and all FxaYABBY were poorly or not expressed in receptacle. Additionally, under the abiotic stresses of low temperature, high salt and drought, the expression of FvYABBY1, FvYABBY3, FvYABBY4 and FvYABBY6 were down-regulated, FvYABBY5 was up-regulated, and FvYABBY2 was up-regulated and then down-regulated. In tobacco leaf cells, the subcellular localization of FvYABBY proteins were in the nucleus. These results provides a foundation for the functional researches of YABBY gene in strawberry.

Objective:To observe the efficacy and safety of vitrectomy combined with subretinal injection of alteplase (tPA) and intravitreal injection of Conbercept in the treatment of large area submacular hemorrhage (SMH) secondary to polypoidal choroidal vasculopathy (PCV).Methods:A retrospective clinical study. From January to September 2021, 32 eyes of 32 patients with massive SMH secondary to PCV diagnosed in the Affiliated Eye Hospital of Nanchang University were included in the study. Large SMH was defined as hemorrhage diameter ≥4 optic disc diameter (DD). There were 32 patients (32 eyes), 20 males and 12 females. The mean age was (72.36±8.62) years. All patients had unilateral disease.The duration from onset of symptoms to treatment was (7.21±3.36) days. All patients underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination. BCVA examination was performed using the international standard visual acuity chart, which was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. The central macular thickness (CMT) was measured by spectral domain-OCT. The average size of SMH was (6.82±1.53) DD. The logMAR BCVA 1.73±0.44; CMT was (727.96±236.40) μm. All patients were treated with 23G pars plana vitrectomy combined with subretinal injection of tPA and intravitreal injection of Conbercept. At 1, 3, 6 and 12 months after treatment, the same equipment and methods were used for relevant examinations before treatment. The changes of BCVA and CMT, the clearance rate of macular hemorrhage, and the complications during and after surgery were observed. BCVA and CMT before and after treatment were compared by repeated measures analysis of variance.Results:Compared with before treatment, BCVA gradually increased at 1, 3, 6 and 12 months after treatment, and the differences were statistically significant ( F=77.402, P<0.001). There was no significant difference in BCVA between any two groups at different time points after treatment ( P>0.05). Correlation analysis showed that BCVA at 12 months after treatment was negatively correlated with the course of disease ( r=-0.053, P=0.774). One week after treatment, macular hemorrhage was completely cleared in 30 eyes (93.75%, 30/32). The CMT was (458.56±246.21), (356.18±261.46), (345.82±212.38) and (334.64±165.54) μm at 1, 3, 6 and 12 months after treatment, respectively. Compared with before treatment, CMT decreased gradually after treatment, and the difference was statistically significant ( F=112.480, P<0.001). There were statistically significant differences in different follow-up time before and after treatment ( P<0.001). The number of treatments combined with Conbercept during and after surgery was (4.2±1.8) times. At the last follow-up, there was no recurrence of SMH, retinal interlamellar effusion and other complications. Conclusion:Subretinal injection of tPA combined with intravitreal injection of Conbercept is safe and effective in the treatment of large SMH secondary to PCV, and it can significantly improve the visual acuity of patients.

Objective To investigate the relationship between serum levels of chitinase-3-like protein 1(CHI3L1)and hypoxia inducible factor-1α(HIF-1α)with the occurrence of liver fibrosis in patients with chronic hepatitis B(CHB)complicated with liver cirrhosis.Methods A total of 90 patients with CHB compli-cated with liver cirrhosis who were treated in Weinan Central Blood Station from March 2021 to September 2023 were selected as the liver cirrhosis group.Additionally,90 patients with CHB during the same period were regarded as the CHB group.According to whether patients with CHB complicated with liver cirrhosis had developed liver fibrosis,they were separated into a non fibrosis group(42 cases)and a fibrosis group(48 cases).Enzyme-linked immunosorbent assay was applied to detect serum levels of interleukin-6(IL-6),high-sensitivity C-reactive protein(hs-CRP),procalcitonin(PCT),CHI3L1,and HIF-1α.Fully automated biochem-ical analyzer was applied to detect levels of glutamate aminotransferase(ALT),aspartate aminotransferase(AST),and alkaline phosphatase(ALP),radioimmunoassay was applied to detect levels of hyaluronic acid(HA),laminin(LN),type Ⅳ collagen(Ⅳ-C),and type Ⅲ procollagen(PC Ⅲ).Pearson correlation was ap-plied to analyze the correlation between CHI3L1,HIF-1α levels and inflammation and liver fibrosis indicators.Receiver operating characteristic curve was applied to analyze the diagnostic value of CHI3L1 and HIF-1α for liver fibrosis in patients with CHB combined with liver cirrhosis.Z-test was applied to compare the differences in the area under the curve(AUC).Results The levels of CHI3L1 and HIF-1α in the liver cirrhosis group were higher than those in the CHB group(P＜0.05),while the levels of IL-6,PCT,CHI3L1,HIF-1α,HA,LN,Ⅳ-C,and PCⅢ in the fibrosis group were higher than those in the non fibrosis group(P＜0.05).The levels of CHI3L1 and HIF-1α were positively correlated with IL-6,PCT,HA,LN,Ⅳ-C,and PC Ⅲ levels(P＜0.05).The AUC of CHI3L1 and HIF-1α in diagnosing liver fibrosis in patients with CHB complicated with liver cirrhosis was 0.810 and 0.801,respectively.The AUC of their combined diagnosis was 0.909,which was bet-ter than their individual diagnosis(Zcombination-CHI3L1=2.893,Zcombination HIF-1α=3.360,P＜0.05).Conclusion The levels of CHI3L1 and HIF-1α are higher in the serum of patients with CHB combined with liver cirrhosis who also had fibrosis,and are positively correlated with liver fibrosis indicators HA,LN,Ⅳ-C,and PC Ⅲ.The combina-tion of the two has high value in diagnosing liver fibrosis in patients with CHB combined with liver cirrhosis,and has certain clinical reference significance.

SUN gene is a group of key genes regulating plant growth and development. Here, SUN gene families of strawberry were identified from the genome of the diploid Fragaria vesca, and their physicochemical properties, genes structure, evolution and genes expression were also analyzed. Our results showed that there were thirty-one FvSUN genes in F. vesca and the FvSUNs encoded proteins were classified into seven groups, and the members in the same group showed high similarity in gene structures and conservative motifs. The electronic subcellular localization of FvSUNs was mainly in the nucleus. Collinearity analysis showed that the members of FvSUN gene family were mainly expanded by segmental duplication in F. vesca, and Arabidopsis and F. vesca shared twenty-three pairs of orthologous SUN genes. According to the expression pattern in different tissues shown by the transcriptome data of F. vesca, the FvSUNs gene can be divided into three types: (1) expressed in nearly all tissues, (2) hardly expressed in any tissues, and (3) expressed in special tissues. The gene expression pattern of FvSUNs was further verified by quantitative real-time polymerase chain reaction (qRT-PCR). Additionally, the seedlings of F. vesca were treated by different abiotic stresses, and the expression level of 31 FvSUNs genes were assayed by qRT-PCR. The expression of most of the tested genes was induced by cold, high salt or drought stress. Our studies may facilitate revealing the biological function and molecular mechanism of SUN genes in strawberry.

In this study, a new Bacillus velezensis strain Bv-303 was identified and its biocontrol effect against rice bacterial-blight (BB) disease caused by Xanthomonas oryzae pv. oryzae (Xoo) was investigated. Cell-free supernatant (CFS) of strain Bv-303 under different growth conditions were prepared to test the antagonistic activity and stability against Xoo by the Oxford-cup method in vitro. The antibacterial effect of strain Bv-303 to BB disease in rice were further analyzed in vivo by spraying the cell-culture broth (CCB), CFS and cell-suspension water (CSW), respectively, on the rice leaves inoculated with Xoo. Additionally, rice seeds germination rate and seedling growth under the strain Bv-303 CCB treatment were tested. The results showed that the strain Bv-303 CFS significantly inhibited Xoo growth by 85.7%‒88.0% in vitro, which was also stable under extreme environment conditions such as heat, acid, alkali and ultraviolet light. As tested in vivo, spraying the CCB, CFS or CSW of strain Bv-303 on the Xoo-infected leaves enhanced rice plant resistance to BB disease, with CCB showing the highest increase (62.7%) in disease-resistance. Notably, CCB does not have negative effects on rice seed germination and seedling growth. Therefore, strain Bv-303 has great potential for biocontrol of the rice BB disease.
