[PMID: 36864483 PMCID: PMC9979463 DOI: 10.1186/s13007-023-00993-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 02/09/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Bamboo is a perennial and renewable biomass forest resource and its leaf flavonoid is an antioxidant for biological and pharmacological research. The established genetic transformation and gene editing systems in bamboo are significantly limited by the dependence on bamboo regeneration capability. The way to improve the flavonoid content in bamboo leaves through biotechnology is still not feasible. RESULTS Here, we developed an in-planta, Agrobacterium-mediated gene expression method for exogenous genes via wounding and vacuum in bamboo. We demonstrated that the RUBY served as a reporter efficiently expressed in bamboo leaves and shoots, albeit unable to integrate into the chromosome. We have also developed a gene editing system by creating an in situ mutant of the bamboo violaxanthin de-epoxidase (PeVDE) gene in bamboo leaves, with lower NPQ values under the fluorometer, which can serve as a native reporter for gene editing. Furthermore, the bamboo leaves with increased flavonoid content were achieved by knocking out the cinnamoyl-CoA reductase genes. CONCLUSIONS Our method can be applied for the functional characterization of novel genes in a short time and is helpful for bamboo leaf flavonoid biotechnology breeding in the future.

THE PLANT JOURNAL : FOR CELL AND MOLECULAR BIOLOGY 2023; 113:1095-1101. [PMID: 36587294 DOI: 10.1111/tpj.16094] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 12/18/2022] [Accepted: 12/29/2022] [Indexed: 06/17/2023]
Abstract
The application of DNA-protein interaction reporter assays for relational or ratiometric measurements within an experimental system is popular in biological research. However, the existing reporter-based interaction assays always require special equipment, expensive chemicals, and a complicated operation. Here, we developed a DNA-protein interaction technology integrating two visible reporters, RUBY and UV-visible GFP (eYGFPuv), which allows the expression of the cassette reporter contained cis-acting DNA element (DE) fused upstream of TATA box and RUBY, and a constitutive promoter regulating eYGFPuv in the same construct. The interaction of transcription factor (TF) and the DE can be detected by co-expressed the cassette reporter and TF in tobacco leaves where the cassette reporter alone serves as a control. We also revealed that eight function-unknown bamboo AP2/ERFs interacted with the DE of ANT-AP2R1R2 (ABE), DRE (DBE), GCC-box (EBE), and RAV1 binding element (RBE), respectively, which are consistent with the results by dual-luciferase reporter assays. Thus, the dual-visible reporters offer a convenient, visible, and cost-saving alternative to other existing techniques for DNA-protein interaction in plants.

Abstract
OBJECTIVE To construct a human health literacy indicator system for prevention of parasitic diseases based on Delphi method. METHODS Based on literature reviews and expert interviews, a questionnaire was designed and a two-round Delphi consultation was performed. A human health literacy indicator system for prevention of parasitic diseases was constructed according to the deletion criteria and experts' advice. RESULTS A total of 14 experts completed the two-round consultation. The second-round authority coefficients were 0.91 to 0.96 for the first-level indicators, 0.87 to 0.97 for the second-level indicators and 0.86 to 0.97 for the third-level indicators. A human health literacy indicator system for prevention of parasitic diseases was constructed with the main framework of basic knowledge and awareness, healthy behaviors, and healthy skills, which contained 3 first-level indicators, 12 second-level indicators and 48 third-level indicators. Among the three first-level indicators, basic knowledge and awareness had the highest weighting coefficient (0.336 5), followed by healthy behaviors (0.334 9), and healthy skills had the lowest weighting coefficient (0.328 6). The three secondary-level indicators with the highest combined weights included awareness of the epidemic status (0.088 2), awareness of the resource of infection (0.085 8) and basic awareness of parasitic diseases (0.085 5). CONCLUSION A human health literacy indicator system for prevention of parasitic diseases is preliminarily constructed, which provides insights into the development of health literacy evaluation tools for prevention of parasitic diseases in the new era.

Abstract
OBJECTIVE To investigate the effect of recombinant Schistosoma japonicum egg ribonuclease SjCP1412 (rSjCP1412) on proliferation, cell cycle, apoptosis and activation of human hepatic stellate cells LX-2 in vitro, and explore the underlying mechanisms. METHODS The rSjCP1412 protein was expressed in Escherichia coli BL21 by prokaryotic expression, and the highly purified soluble rSjCP1412 protein was prepared by Ni NTA affinity chromatography and urea gradient refolding dialysis. Yeast RNA was digested using 12.5, 25.0, 50.0 µg rSjCP1412 proteins at 37 °C for 2, 3, 4 h, and the enzymatic products were electrophoresed on 1.5% agarose gel to observe the RNAase activity of rSjCP1412 protein. The proliferation of LX-2 cells stimulated by different doses of rSjCP1412 protein for 48 hours was measured using CCK-8 assay, and the apoptosis of LX-2 cells stimulated by different doses of rSjCP1412 protein for 48 hours was detected using the Annexin V-FITC/PI double staining, while the percentage of LX-2 cells at G0/G1, S and G2/M phases of cell cycle following stimulation with different doses of rSjCP1412 protein for 48 h was detected by DAPI staining. The type I collagen, type III collagen and α-smooth muscle actin (α-SMA) mRNA expression was quantified using quantitative florescent real-time PCR (qPCR) assay and Western blotting at transcriptional and translational levels in LX-2 cells following stimulation with different doses of rSjCP1412 protein for 48 h, while soluble egg antigen (SEA) served a positive control and PBS without rSjCP1412 protein as a normal control in the above experiments. The expression of collagen I, α-SMA and Smad4 protein was determined using Western blotting in LX-2 cells following stimulation with rSjCP1412 protein, transforming growth factor-β1 (TGF-β1) alone or in combination, to examine the signaling for the effect of rSjCP1412 protein on LX-2 cells. RESULTS The rSjCP1412 protein was successfully expressed and the highly purified soluble rSjCP1412 protein was prepared, which had a RNase activity. Compared with the normal group, the survival rates of LX-2 cells significantly decreased post-treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein and SEA for 48 h (F = 22.417 and 20.448, both P values < 0.05). The apoptotic rates of LX-2 cells significantly increased post-treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein for 48 h (F = 11.350, P < 0.05), and treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein for 48 h resulted in arrest of LX-2 cells in G0/G1 phase (F = 20.710, P < 0.05). Treatment with 12.5, 25.0, 50.0 µg/mL rSjCP1412 protein for 48 h caused a significant reduction in relative expression levels of collagen I (F = 11.340, P < 0.05), collagen III (F = 456.600, P < 0.05) and α-SMA mRNA (F = 23.100, P < 0.05) in LX-2 cells, and both rSjCP1412 protein and SEA treatment caused a significant reduction in collagen I (F = 1 302.000, P < 0.05), α-SMA (F = 49.750, P < 0.05) and Smad4 protein expression (F = 52.420, P < 0.05) in LX-2 cells. In addition, rSjCP1412 protein treatment inhibited collagen I (F = 66.290, P < 0.05), α-SMA (F = 31.300, P < 0.05) and Smad4 protein expression (F = 27.010, P < 0.05) in LX-2 cells activated by TGF-β1. CONCLUSIONS rSjCP1412 protein may induce apoptosis of LX-2 cells and inhibit proliferation, cell cycle and activation of LX-2 cells through down-regulating Smad4 signaling molecules.

Abstract
BACKGROUND Prevention of surgical site infection (SSI) after gastrectomy has received increasing attention. Prophylactic incisional wound irrigation has been advocated to reduce SSI, but the choice of solution remains under debate. AIMS To compare the efficacies of wound irrigation with normal saline (NS) and povidone-iodine (PVI) for the prevention of SSI after gastrectomy, and to identify the risk factors for SSI. METHODS This randomized, single-centre clinical trial included 340 patients with gastric cancer. They were assigned at random into two groups (ratio 1:1) to receive either 0.9% NS or 1.0% PVI solution for incisional irrigation before wound closure. The primary endpoint was postoperative SSI within 30 days of gastrectomy, and the secondary endpoint was the length of hospital stay. FINDINGS In total, 333 patients were included in the modified intent-to-treat group, and the SSI rate did not differ significantly between the PVI group (11/167, 6.59%) and the NS group (9/166, 5.42%) [odds ratio (OR) 1.131, 95% confidence interval (CI) 0.459-3.712; P=0.655]. Moreover, the difference between the two groups in terms of length of hospital stay was not significant (P=0.301). Body mass index (BMI) (OR 2.639, 95% CI 1.040-6.694; P=0.041) and postoperative complications (OR 2.565, 95% CI 1.023-6.431; P=0.045) were identified as independent risk factors for SSI. CONCLUSIONS NS and PVI had similar efficacy as prophylactic wound irrigation for the prevention of SSI after gastrectomy. The risk of SSI was higher in patients with high BMI or postoperative complications.

Abstract
Since the global pandemic of coronavirus disease 2019 (COVID-19) in late 2019, artificial intelligence technology has shown increasing values in the research and control of tropical infectious diseases. The introduction of artificial intelligence technology has shown remarkable effectiveness to reduce the diagnosis and treatment burdens, reduce missing diagnosis and misdiagnosis, improve the surveillance and forecast ability and enhance the medicine and vaccine development efficiency. This paper summarizes the current applications of artificial intelligence in tropical infectious disease control and research and discusses the important values of artificial intelligence in disease diagnosis and treatment, disease surveillance and forecast, vaccine and drug discovery, medical and public health services and global health governance. However, artificial intelligence technology suffers from problems of single and inaccurate diagnosis, poor disease surveillance and forecast ability in open environments, limited capability of intelligent system services, big data management and model interpretability. Hereby, we propose suggestions with aims to improve multimodal intelligent diagnosis of multiple tropical infectious diseases, emphasize intelligent surveillance and forecast of vectors and high-risk populations in open environments, accelerate the research and development of intelligent management system, strengthen ethical security, big data management and model interpretability.

Abstract
Objective: To analyze the withdrawal in patients receiving methadone maintenance treatment (MMT) and its related influencing factors in Hubei province. Methods: The patients receiving MMT in clinics in Hubei province were selected from June 2006 to December 2021. The general demographic data, drug abuse history, and MMT information were collected. The survival data of patients with MMT were analyzed by the Kaplan-Meier method, and the Cox proportional hazards model was used for multivariate analysis. Results: A total of 26 716 patients receiving MMT were included in this study, and the gender ratio between men and women was 3.34∶1(20 557∶6 159). The duration of MMT was 0.01-15.72 years, and the median duration was 2.21 (95%CI: 2.16-2.26) years. At the end of the follow-up, the withdrawal proportion was 86.75% (23 175/26 716). MMT's 0-year, 2-year, 4-year, 9-year and 14-year cumulative probabilities appeared as 67.61%, 40.24%, 30.03%, 15.49% and 6.56%, respectively. Results from the Cox proportional hazards regression model showed that the factors of the withdrawal risk were higher in patients receiving MMT, including minority nationality (HR=1.66,95%CI:1.52-1.82), having jobs (HR=1.05, 95%CI:1.01-1.08), no history of compulsory isolation or detoxification (HR=1.04, 95%CI:1.01-1.09) and the enrollment in 2016-2021 (HR=1.46,95%CI:1.35-1.58). The factors of the withdrawal risk were lower in patients receiving MMT, including 60-year-olds or above (HR=0.56,95%CI:0.42-0.75), college degree or above education level (HR=0.83, 95%CI:0.75-0.91), outpatient services of other cities (HR=0.90, 95%CI:0.87-0.93), drug use for 20 years or more (HR=0.72, 95%CI:0.66-0.80), 90 mg or more per daily dosage (HR=0.73,95%CI:0.69-0.78) and the enrollment in 2011-2015 (HR=0.93,95%CI:0.89-0.97). Conclusions: The withdrawal proportions of patients receiving MMT were high in Hubei province. The withdrawal influencing factors were complex. The daily dose was an essential factor that can be intervened under the safe MMT condition, and a higher dose should be appropriately prescribed.

Abstract
Panax notoginseng round spot disease (PRSD), caused by Mycocentrospora acerina, is the main leaf disease occurring in cultured P. notoginseng. Aiming to find a safe and efficient control method for PRSD, we studied the disease characteristics of PRSD and the optimal growth conditions of M. acerina and evaluated the efficacy of rain-shelter cultivation in PRSD control. Moreover, we described M. acerina based on morphological characterization and molecular analyses (ITS, ACT, LSU, and TEF-1α). The optimum temperature for M. acerina conidial germination was found to be 14 to 22°C. Furthermore, leaf surface wetness for at least 4 h is required for conidial germination, and conidia can successfully infect P. notoginseng when the leaf wetness lasts for more than 8 h. Additionally, rainwater splashing determines the conidial transfection distance, which is less than 2 m. Finally, our study revealed that rain-shelter cultivation is an effective and simple physical prevention strategy to control PRSD, with an average efficacy of up to 100%.

Abstract
Bamboo shoot is one of nutritious vegetables in China. However, the edible quality of fresh bamboo shoots deteriorates easily after harvest. Here, morphological, physiological, transcriptomic and microRNA sequencing analyses were conducted to investigate the postharvest characteristics of moso bamboo (Phyllostachys edulis) shoots. Rapid decreases of soluble sugars, structural polysaccharides and hydrolyzed tannins, and increases of lignin and condensed tannins were observed in the postharvest bamboo shoots. Differentially expressed genes (DEGs) and miRNAs with opposite trends were mainly enriched in structural polysaccharide metabolism, starch and sucrose metabolism and glycolysis pathways, which were consistent with the changes of carbohydrates. A co-expression network of carbohydrate metabolism was constructed, which was verified by qPCR and yeast one-hybrid (Y1H) assay. Furthermore, the function of one hub glycosyltransferase gene was validated in Arabidopsis, which confirmed that it was involved in xylan biosynthesis. These results are of great significance for revealing the carbohydrate metabolism mechanisms of postharvest bamboo shoots and provide a potential candidate gene for molecular breeding related to xylan in the future.

Abstract
Culm color variation is an interesting phenomenon that contributes to the breeding of new varieties of ornamental plants during domestication. De-domesticated variation is considered ideal for identifying and interpreting the molecular mechanisms of plant mutations. However, the variation in culm color of bamboo remains unknown. In the present study, yellow and green culms generated from the same rhizome of Phyllostachys vivax cv. Aureocaulis (P. vivax) were used to elucidate the molecular mechanism of culm color formation. Phenotypic and physiological data showed that environmental suitability was higher in green culms than in yellow culms. High-throughput sequencing analysis showed 295 differentially expressed genes (DEGs) and 22 differentially expressed miRNAs (DEMs) in two different colored bamboo culms. There were 103 DEM-DEG interaction pairs, of which a representative "miRNA-mRNA" regulatory module involved in photosynthesis and pigment metabolism was formed by 14 DEM-DEG pairs. The interaction of the three key pairs was validated by qPCR and dual-luciferase assays. This study provides new insights into the molecular mechanism of miRNAs involved in P. vivax culm color formation, which provides evidence for plant de-domestication and is helpful for revealing the evolutionary mechanism of bamboo.

Abstract
Objective: To investigate the dynamic change of the secundum atrial septal defect (ASD) throughout the cardiac cycle, and assess its impact on occluder selection. Methods: This study retrospectively analyzed 35 patients with ASD who received electrocardiogram-gated coronary CT angiography (CCTA) throughout the cardiac cycle as well as interventional closure therapy in Fuwai Hospital from December 2016 to December 2019. The raw data were reconstructed into 20 phasic images of RR intervals (RRI) ranging from 0 to 95% in an increment of 5% and transmitted to a workstation for postprocessing. For each phase image, CT virtual endoscopy reconstruction technique (CTVE) was used to provide views of ASD. Axial sequence assisted CT volumetric measurement (CTAS) was used to calculate the maximum dimensions in axial planes (Da) and in superior-inferior direction (Db). Using a formula for converting circumference to diameter, the equivalent circle dimensions were calculated (De, De=minor axis+2 (major axis-minor axis)/3). Taking the data of 75% RRI phase, the patients were divided into Da75%RRI≥Db75%RRI group and Da75%RRI<Db75%RR group. According to the postoperative chest X-ray, the waist diameter of the occluder in the left anterior oblique plain film was measured, and its correction value (CR-PODlaoc) was calculated with the correction formula. Scatter plots of the changes of the mean values of Da, Db and De with the cardiac cycle were presented. The change and ratio of measured values of Da and De at 35% and 75% RRI was calculated. The ratio of De change to Da change in Da75%RRI≥Db75%RRI group and Da75%RRI<Db75%RR group was calculated, respectively, and compared between groups. Pearson correlation analysis was used to explore the correlation between CR-PODlaoc and De35%RRI and De75%RRI. Results: A total of 35 patients, aged (42.7±15.0) years, including 10 males, were included. Among 35 patients, 8 cases were divided into group Da75%RRI≥Db75%RRI and 27 cases into group Da75%RRI<Db75%RRI. Both Da and Db regularly changed at each phase throughout the cardiac cycle. The Da changed significantly, with a maximum at phase of 35%-45% of RRI, and a minimum between phases of 90% and 0 of RRI. While the Db showed insignificant changes during phases of 10%-90% RRI, and increased at 0-10% of RRI, then reduced in the remaining phases. The change of Da was (6.35±2.46) mm, and the ratio of Da values at 35% and 75% RRI was 0.77±0.08. The change of De was (2.28±1.32) mm, and the ratio of De at 35% and 75% RRI was 0.93±0.05. The ratio of De change to Da change in the Da75%RRI≥Db75%RRI group was 0.67±0.13; while the ratio was 0.34±0.05 in Da75%RRI<Db75%RR group, and there was significant difference between the two groups (P=0.02). CR-PODlaoc was positively correlated with De35% RRI (r=0.99, P<0.001) and De75% RRI (r=0.98, P<0.001). Conclusions: Most secundum ASDs show oval shape with Db>Da. Db is basically constant while Da changes significantly during cardiac cycle (10%-90% RRI). Nonetheless, both values peak and maintain the maximum status at end-systolic phase (35%-45% RRI). For patients with huge ASD, occluder selection should be based on the De at 35% RRI phase, which is helpful for the successful intervention.

Abstract
OBJECTIVE To investigate the value of HBV RNA for predicting the therapeutic effect of long-term entecavir (ETV) antiviral therapy in patients with chronic hepatitis B (CHB). METHODS Serum samples were collected from 59 CHB patients treated with ETV for 96 or 108 months. HBV RNA levels, HBV DNA levels, and serological marker (HBeAg) levels were measured at baseline and 3, 6, 9, 12, 36, 72, and 96 (or 108) months during the therapy. RESULTS Although HBV RNA level decreased after 12 and 36 months of ETV antiviral therapy, no significance changes occurred in HBV RNA negative conversion rate (P>0.05). After 72 months of treatment or longer, 33 patients had HBV RNA levels lower than 100 copies/mL, and among them 29 patients had HBV RNA levels lower than the detection limit, and HBV RNA negative conversion rate was statistically significant (P < 0.05). A lower HBV RNA level was associated with a higher HBeAg negative conversion rate (P < 0.05). Age and HBV RNA level were positively correlated with HBeAg negative conversion rate (P < 0.05). CONCLUSION Prolonged ETV antiviral therapy results in better clearance of HBV RNA and a higher negative conversion rate in CHB patients. The length of antiviral therapy and age are positively correlated with the negative conversion rate of HBV RNA, and earlier administration of the antiviral treatment achieves better therapeutic effect. Serum HBV RNA level can be used as an indicator for predicting conversion to negative HBeAg in CHB patients receiving ETV therapy.

FRONTIERS IN PLANT SCIENCE 2022; 13:927949. [PMID: 36035723 PMCID: PMC9403991 DOI: 10.3389/fpls.2022.927949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 07/21/2022] [Indexed: 06/15/2023]
Abstract
Plants employ an array of photoprotection mechanisms to alleviate the harmful effects of high light intensity. The violaxanthin cycle, which is associated with non-photochemical quenching (NPQ), involves violaxanthin de-epoxidase (VDE), and zeaxanthin epoxidase (ZEP) and is one of the most rapid and efficient mechanisms protecting plants under high light intensity. Woody bamboo is a class of economically and ecologically important evergreen grass species widely distributed in tropical and subtropical areas. However, the function of VDE in bamboo has not yet been elucidated. In this study, we found that high light intensity increased NPQ and stimulated the de-epoxidation of violaxanthin cycle components in moso bamboo (Phyllostachys edulis), whereas, samples treated with the VDE inhibitor (dithiothreitol) exhibited lower NPQ capacity, suggesting that violaxanthin cycle plays an important role in the photoprotection of bamboo. Further analysis showed that not only high light intensity but also extreme temperatures (4 and 42°C) and drought stress upregulated the expression of PeVDE in bamboo leaves, indicating that PeVDE is induced by multiple abiotic stresses. Overexpression of PeVDE under the control of the CaMV 35S promoter in Arabidopsis mutant npq1 mutant could rescue its NPQ, indicating that PeVDE functions in dissipating the excess absorbed light energy as thermal energy in bamboo. Moreover, compared with wild-type (Col-0) plants, the transgenic plants overexpressing PeVDE displayed enhanced photoprotection ability, higher NPQ capacity, slower decline in the maximum quantum yield of photosystem II (F v /F m ) under high light intensity, and faster recovery under optimal conditions. These results suggest that PeVDE positively regulates the response to high light intensity in bamboo plants growing in the natural environment, which could improve their photoprotection ability through the violaxanthin cycle and NPQ.
