Preparation of a hydrolyzed yeast ß-glucan chromium(III) complex and evaluation of its hypoglycemic activity and sub-acute toxicity.

Yeast ß-glucan (BYG) possesses extremely low solubility that has limited its applications. In this study, we hydrolyzed BYG using snail enzyme to obtain hydrolyzed yeast ß-glucan (HBYG) with desirable water solubility and hypoglycemic activity. On the basis of HBYG, HBYG­chromium(III) complex (HBYG-Cr) was synthesized. The molecular weight of the complex was 4.41 × 104 Da, and the content of trivalent chromium was 8.95 %. The hydroxyl groups of HBYG participated in the coordination and formed the chromium complex. The space conformations of HBYG exhibited remarkable changes after complex formation. HBYG-Cr existed mainly in an amorphous state and presented good dispersibility, and the surface was uneven. The hypoglycemic activity of HBYG-Cr was studied in db/db and C57 mice. The results showed that HBYG-Cr had good hypoglycemic activity. Histopathological studies demonstrated that the liver, kidney, pancreas, and skeletal muscle in the treatment group were significantly improved compared with those in the diabetic model group. The sub-acute toxicity of HBYG-Cr was studied in KM mice and the results indicated that the complex did not cause adverse reactions or toxic side effects. This study broadened the application of yeast ß-glucan and provided an important reference for the development of hypoglycemic functional foods and drugs.

Approved immune checkpoint inhibitors in hepatocellular carcinoma: a large-scale meta-analysis and systematic review.

A meta-analysis was performed to assess the benefits and safety profile of approved immune checkpoint inhibitors in hepatocellular carcinoma patients. Eligible studies were searched from Cochrane, Embase, and PubMed databases based on a well-established strategy. Following the exclusion of ineligible studies, 12 studies were included in this meta-analysis. Compared with control group, immune checkpoint inhibitors were associated with improved ORR (OR 3.03, 95% CI 2.26-4.05, P < 0.00001), SD (OR 0.77, 95% CI 0.62-0.95, P = 0.02), OS (HR 0.75, 95% CI 0.68-0.83, P < 0.00001), and PFS (HR 0.74, 95% CI 0.63-0.87, P < 0.0003). However, no significant differences were observed in DCR (OR 1.33, 95% CI 0.97-1.81, P = 0.07), PD (OR 0.90, 95% CI 0.67-1.21, P = 0.48), and all caused any-grade adverse events (OR 1.22, 95% CI 0.62-2.39, P = 0. 57), all caused ≥ grade 3 adverse events (OR 1.10, 95% CI 0.97-1.25, P = 0.14), treatment-related any-grade adverse events (OR 1.13, 95% CI 0.55-2.32, P = 0.73), and treatment-related ≥ grade 3 events (OR 0.82, 95% CI 0.34-1.97, P = 0.65) between the two groups. After subgroup analysis conducted, patients in the immune checkpoint inhibitor group compared with targeted drug group showed significant improvements in OS (HR 0.74, 95% CI 0.66-0.84, P < 0.00001) and PFS (HR 0.75, 95% CI 0.61-0.91, P = 0.004). Immune checkpoint inhibitors have demonstrated peculiar benefits in the treatment of HCC with an acceptable safety profile. Compared to targeted drugs, immune checkpoint inhibitors still offer advantages in the treatment of hepatocellular carcinoma. However, there is still considerable room for further improvement.

The complete chloroplast genome sequence of Malus × adstringens Zabel 'Hopa' (Rosaceae).

Malus × adstringens Zabel 'Hopa' is an important crabapple cultivar with significant ornamental value. Here, we assembled its complete chloroplast (cp) genome using the next-generation sequencing technology to clarify the phylogenetic relationships in Malus. The total length of the complete chloroplast genome was 160,230 base pairs (bp) with a GC content of 36.50%, consisting of a large single-copy (LSC) region with a sequence length of 88,310 bp, a small single-copy (SSC) region with a sequence length of 19,196 bp, and a pair of inverted repeat (IR) regions of 26,362 bp. The complete chloroplast genome contained 128 genes, namely 84 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. In addition, 73 SSRs were found in the M. 'Hopa' cp genome. The phylogenetic relationship of M. 'Hopa' in Malus is closely related to M. spectabilis (Aiton) Borkh. and then to M. sieversii (Lebed.) M. Roem. Our results demonstrate that it is feasible to resolve the phylogenetic relationships of crabapple cultivars and identify their putative maternal lineages using cp genomic data.

UPLC-Q TOF-MS-Based metabolomics and anti-myocardial ischemia activity of Dioscoreae Nipponicae Rhizoma from different geographical origins.

The dried rhizome of Dioscorea nipponica Makino ("Chuanshanlong" in Chinese) is a medicinal herb with multiple major producing areas. The main objective of this study was the comparative profiling of Dioscoreae Nipponicae Rhizoma (DNR) from various geographical origins. A hypoxia/reoxygenation-induced H9c2 cell injury model was established, and the antimyocardial ischemia activity of DNR samples from different origins was detected using the cell counting kit-8 (CCK-8) method. The result showed that the antimyocardial ischemia potential of DNR samples from the Heilongjiang province was higher than that of the other studied samples. Subsequently, a plant metabolomics technique utilizing ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q TOF-MS) was used to determine the differences in DNR samples from various geographical origins. Forty compounds, including steroidal saponins, free fatty acids, and organic acids, were tentatively identified based on UPLC-Q TOF-MS fragmentation pathways and via comparison with available reference standards. Partial least squares discriminant analysis was performed to estimate the differences in DNR samples from different origins. Five compounds were significantly up-regulated and correlated with antimyocardial ischemia in DNR samples from Heilongjiang province. Molecular docking was used to discern the interactions of key markers with the active sites of the target protein. The findings signified that UPLC-Q TOF-MS metabolomics coupled with molecular docking is a powerful tool to rapidly identify the quality control characteristics of DNR samples and their products. The research provides a direction for the rational utilization of DNR.

Molecular Structure and Variation Characteristics of the Plastomes from Six Malus baccata (L.) Borkh. Individuals and Comparative Genomic Analysis with Other Malus Species.

Malus baccata (L.) Borkh. is an important wild species of Malus. Its rich variation types and population history are not well understood. Chloroplast genome mining plays an active role in germplasm identification and genetic evolution. In this study, by assembly and annotation, six complete cp genome sequences, ranging in size from 160,083 to 160,295 bp, were obtained. The GC content of stable IR regions (42.7%) was significantly higher than that of full length (36.5%) and SC regions (LSC-34.2%, SSC-30.4%). Compared with other Malus species, it was found that there were more sites of polymorphisms and hotspots of variation in LSC and SSC regions, with high variation sites including trnR/UCU-atpA, trnT/UGU-trnL/UAA, ndhF-rpl32 and ccsA-ndhD. The intraspecific and interspecific collinearity was good, and no structural rearrangement was observed. A large number of repeating elements and different boundary expansions may be involved in shaping the cp genome size. Up to 77 or 78 coding genes were annotated in the cp genomes of M. baccata, and high frequency codons such as UUA (Leu), GCU (Ala) and AGA (Arg) were identified by relative synonymous codon usage analysis. Phylogeographic analysis showed that 12 individuals of M. baccata clustered into three different groups with complex structure, whereas variant xiaojinensis (M.H. Cheng & N.G. Jiang) was not closely related to M. baccata evolutionarily. The phylogenetic analysis suggested that two main clades of different M. baccata in the genus Malus were formed and that I and II diverged about 9.7 MYA. In conclusion, through cp genome assembly and comparison, the interspecific relationships and molecular variations of M. baccata were further elucidated, and the results of this study provide valuable information for the phylogenetic evolution and germplasm conservation of M. baccata and Malus.

[Rapid identification of components in Wuzhuyu Decoction using UHPLC Q-Exactive Orbitrap MS~n and molecular network technology].

Wuzhuyu Decoction, the classical formula recorded in the Treatise on Febrile Diseases(Shang Han Lun), has been included in the Catalogue of Ancient Classic Prescriptions(the First Batch). Consisting of Euodiae Fructus, Ginseng Radix et Rhizoma, Zingiberis Rhizoma Recens, and Jujubae Fructus, it is effective in warming the middle, tonifying deficiency, dispelling cold, and descending adverse Qi, and is widely applied clinically with remarkable efficacies. For a classical formula, the chemical composition is the material basis and an important premise for quantity value transfer. This study aimed to establish a rapid identification method of chemical components in Wuzhuyu Decoction by high-resolution mass spectrometry(HR-MS) and molecular network. AQUITY UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 µm) was used for sample separation, and acetonitrile-0.1% formic acid in water was used as mobile phases for gradient elution. Q-Exactive Orbitrap MS data were collected in positive and negative ion modes, and GNPS molecular network was plotted according to the similarity of MS/MS fragmentation modes. Cytoscape 3.6.1 was used to screen molecular clusters with similar structures. Finally, the chemical components of Wuzhuyu Decoction were rapidly identified according to the controls, as well as the information of retention time, accurate relative molecular weight of HR-MS, and MS/MS multistage fragments. A total of 105 chemical components were identified in Wuzhuyu Decoction. This study can provide data for the follow-up quality control, standard substance research, and pharmacodynamic material research on Wuzhuyu Decoction, as well as references for the rapid qualitative analysis of the chemical components of Chinese medicine.

[Plasma components of Danzhi Xiaoyao Formula and its mechanism of action in treating perimenopausal depression based on UPLC-Q-TOF-MS~E integrated with network pharmacology].

In this study, ultra-performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS~E) was used to analyze the plasma components of Danzhi Xiaoyao Formula after oral administration. Forty-nine plasma components were found in the serum of rats by comparing the compound extract, drug-containing serum, and blank serum. Components, such as 6-hydroxycoumarin, poricoic acid F, deoxoglabrolide, 30-norhederagenin, kanzonol R, 3',6'-di-O-galloylpaeoniflorin, 16α-hydroxytrametenolic acid, 16-deoxyporicoic acid B, 3-O-acetyl-16α-hydroxytrametenolic acid, and 16α,25-dihydroxydehydroeburiconic acid, were first found in rat serum. Behavioral tests, including the tail suspension test, novel object recognition test, and novelty-suppressed feeding test, were conducted for behavioral analysis. It was confirmed that this formula had therapeutic effects on perimenopausal depression. Furthermore, in combination with the network pharmacology method, 53 core targets including MAPK1, HRAS, AKT1, EGFR, and ESR1 were screened, and these targets participated in 165 signaling pathways, including PI3K-AKT, AMPK, VEGFA, MAPK, and HIF-1. In summary, the potential effects of Danzhi Xiaoyao Formula in treating perimenopausal depression are associated with mechanisms in accelerating inflammation repair, improving neuroplasticity, affecting neurotransmitters, regulating estrogen levels, and promoting new blood vessel formation.

The main outcomes were functional disability, perceived recovery, leg and back pain, complications. A random effects model was used to pooled data. Risk ratio (RR), mean difference (MD) and 95% confidence interval (CI) were used to report results. The study protocol was published in PROSPERO (CRD42022302218). Results: 14 trials including 1,106 participants were included in the final analysis. Bilateral laminotomy was significantly more efficacious in improve functionality than laminectomy [MD: -2.94; (95% CI, -4.12 to -1.76)]. Low incidence of iatrogenic instability due to bilateral laminectomy compared with laminectomy [RR: 0.11; (95% CI, 0.02 to 0.59)]. In addition, between those who received bilateral laminotomy and those undergoing laminectomy, the result showed significant difference regarding recovery [RR: 1.31; (95% CI, 1.03 to 1.67)]. Conclusions: This study provides evidence that bilateral laminotomy has advantages in functional recovery, postoperative stability, and postoperative rehabilitation outcomes. Further research is needed to determine whether posterior techniques provide a safe and effective option for conventional laminectomy.

[Status quo of and challenges for research on rust disease in medicinal plants].

Medicinal plants are beneficial to human health. However,most of the major producing regions of medicinal plants suffer from rust disease,which threatens the yield and quality of Chinese medicinal materials,thus causes huge economic loss,and hinders the sustainable development of the Chinese medicine industry. By the end of 2020,rust disease had been reported in medicinal plants of 76 species and 33 families. In the 76 species,79 rust pathogens were detected. The majority of these pathogens belonged to Puccinia( 33,39. 24%),Coleosporium( 14,15. 19%),and Aecidium( 11,13. 92%). Of these 79 rust pathogens,10 were autoecious and 13 were heteroecious. Through literature research,this study reviewed the symptoms,pathogen species,severity and distribution,prevalence and occurrence conditions,and control measures of rust disease in medicinal plants,and thereby summarized the research status of rust disease in medicinal plants and the gap with other plants,which is expected to serve as a reference for further research on rust disease in medicinal plants.

Evolutionary history and functional characterization of Lj-TICAM-a and Lj-TICAM-b formed via lineage-specific tandem duplication in lamprey (Lampetra japonica).

Toll/interleukin-1 receptor domain-containing adaptor molecule (TICAM) genes respond to infections. We identified TICAM-a and TICAM-b in Lampetra japonica and investigated their evolutionary history and potential function via comparative genomics and molecular evolution analyses. They are arranged in tandem and evolved from a multi-exon to a single-exon structure. Lj-TICAM-a and Lj-TICAM-b might be the ancestral gene of the vertebrate TICAM genes. Lj-TICAM-b arose via a lamprey-specific tandem duplication event. Both genes are expressed in many tissues during an immune response, and exhibit different responses to peptidoglycan, indicating their functional divergence. Simultaneous overexpression of both proteins activated nuclear factor κB expression and co-immunoprecipitation assays indicated that they might form a complex for signal transduction. However, unlike in mammals, the TICAM-dependent signaling pathway in lamprey might rely on TRAF3 rather than on TRAF6. These results suggest that both Lj-TICAM-a and Lj-TICAM-b play a role in host defenses.

Chromosome-level genome assembly of Lethenteron reissneri provides insights into lamprey evolution.

The reissner lamprey Lethenteron reissneri, belonging to the class Cyclostomata, serves as a bridge between invertebrates and jawed vertebrates, and is considered the sister group of jawed vertebrates. However, despite this evolutionary significance, the genetic mechanisms underlying the adaptive evolution of the lamprey lineage remain unclear. Here, we assembled a 1.06 Gb chromosome-level draft genome of L. reissneri, with 72 chromosomes (ranging in length from 4.5 Mb to 25.9 Mb) and a scaffold N50 length of 13.23 Mb. Genome quality comparisons revealed that the reissner lamprey genome has higher completeness and contiguity than the previously published sea lamprey and Japanese lamprey genomes. Moreover, reissner lamprey, sea lamprey, and Japanese lamprey species share similar transposable element profiles and Hox gene cluster compositions, suggesting that a burst of transposable element activity and whole genome duplication occurred before their divergence. Additionally, the Lip gene copy numbers, which have been studied for their functions in the host defence system, were found to be expanded uniquely in lamprey lineages, suggesting key roles for these genes in lamprey evolution and adaptation. We also identified two neural-related genes, Nrn1 and Unc13a, with copy number expansions in jawed vertebrates, which may be functionally relevant to the origin of lamprey brains. Hence, this study not only provides the first chromosome-level reference genome for Cyclostomata, but also highlights features of the unique biology and adaptive evolution of the lamprey lineage.

[Advances in assay for transposase-accessible chromatin with high-throughput sequencing].

Assay for transposase accessible chromatin with high-throughput sequencing (ATAC-seq) was developed in 2013. It has the advantages of more convenient operation and higher efficiency for DNA recovery than DNase I hypersensitive site sequencing (DNase-seq) and micrococcal nuclease sequencing (MNase-seq). ATAC-seq currently is the most popular technique of genome-wide mapping for chromatin accessibility. It provides information on binding regions of transcription factors and nucleosome localization on the chromatin. Thus, ATAC-seq is of great significance for studying the epigenetics and molecular mechanisms in chromatin structure. In this review, we compare the advantages and disadvantages of multiple techniques for profiling chromatin accessibility, and summarize the principles, main process, development and applications of ATAC-seq. We hope this review will provide a reference for study of genome-wide mapping for chromatin accessibility, identification of cis-regulatory elements, and dissection of the epigenetic and genetic regulatory networks using the ATAC-seq technology in eukaryotes.

Arthroscopic treatment with canulated screw fixation through very high-posteromedial portal approach versus double bundle suture fixation for avulsion fracture of tibial attachment of posterior cruciate ligament / 中国组织工程研究

BACKGROUND: This team modified the arthroscopic reduction and internal fixation with canulated screw through very high-posteromedial portal approach to perform direct compression. Thus, the pressure of the fracture block is evenly distributed on the healing line, and the operation is convenient and fixed firmly, but its clinical effect remains to be further confirmed. OBJECTIVE: To compare the clinical outcome of arthroscopic reduction and internal fixation with canulated screw through very high-posteromedial portal approach and double bundle suture fixation for avulsion fracture of the tibial attachment of posterior cruciate ligament. METHODS: From January 2011 to May 2017, 60 cases of the avulsion fracture of posterior cruciate ligament (transverse diameter of fracture block > 10 mm) were treated operatively at the Orthopedics and Arthroscopic Ward Two, First Hospital of Qinhuangdao, China. According to different modes of operation in different periods, patients were assigned to two groups. In the canulated screw group (n=31), patients were treated with canulated screw through very high-posteromedial portal approach. In the suture group (n=29), patients were treated with double bundle suture fixation through posteromedial portal approach. General conditions were compared between the two groups. Knee function was assessed with the Intemational Knee Documentation Committee and Lysholm scores. Knee stability was evaluated with KT-2000 and posterior drawer test. RESULTS AND CONCLUSION: (1) All the patients were followed up (range 6-12 months). (2) The average operation time was (63.49±3.97) minutes in the canulated screw group and (87.28±3.46) minutes in the suture group (P < 0.05). At 3 months after surgery, all the patients were healed. (3) At the final follow-up, in the canulated screw group, the negative rate of posterior drawer test was 90%. Lysholm scores were 94.89±4.75. IKDC scores were 94.01±3.25. In the suture group, the negative rate of posterior drawer test was 90%. Lysholm scores were 95.56±3.63. IKDC scores were 95.52±4.72. No significant difference was determined between the two groups (P > 0.05). (4) KT-2000 measurement results revealed that there were no significant differences between the surgical knee and the normal knee in both groups (canulated screw group:(2.53±1.02)mm versus(2.12±0.83)mm;suture group:(2.65±0.82)mm versus(2.19±0.63)mm (P > 0.05). Moreover, no significant difference was detected in the affected knee of KT-2000 results between the two groups. (5) Both arthroscopic reduction with canulated screw through very high-posteromedial portal approach and double bundle suture fixation can achieve satisfactory clinical outcomes, but arthroscopic reduction with canulated screw through very high-posteromedial portal approach in patients with fracture block diameter > 10 mm can result in shorter operation time, more reliable fixation, and thus permit an early postoperative functional exercise.

[Clinical Therapeutic Effect of Oblique Needling with Tuina in Relieving Sacroiliac Joint Injury].

OBJECTIVE: To observe the therapeutic effect of oblique needling in combination with Tuina at the sacroiliac joint for patients experiencing sacroiliac joint injury. METHODS: One hundred and twenty patients with sacroiliac joint injury were randomized into routine Tuina group and oblique needling combined with Tuina (Acu+ Tuina) group (n = 60 in each group). For patients of the Tuina group, routine Tuina as rotating, pressing-rubbing, digital pressing, articular moving, etc. was manipulated at Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 31), Xialiao (BL 30), Huantiao (GB 30), Zhibian (BL 54), Weizhong (BL 40) and sacroiliac joint area. For patients of the Acu+Tuina group, the anatomical points between the bilateral iliac crests and the sacral joints were punctured obliquely with disposable acupuncture needles. The treatment was conducted for 30 min every time, once daily for 3 weeks except weekends. The Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI, concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel) were employed to evaluate the patients' reactions and functional activity changes before and after the treatment. RESULTS: Following the treatment, of the two 60 patients in the Tuina and Acu + Tuina groups, 12 and 26 cases were cured, 20 and 20 experienced marked improvement, 16 and 11 were effective, 12 and 3 invalid, with the effective rates being 80% and 95%, respectively. The effective rate of the Acu+ Tuina group was significantly superior to that of the Tuina group (P<0.05). The VAS scores and OD were considerably decreased in both groups after the treatment and were significantly lower in the Acu+Tuina group than in the Tuina group (P<0.01). CONCLUSION: Oblique needling the anatomical points in the sacroiliac joint region combined with Tuina manipulation is evidently better than simple Tuina in reducing pain and in improving functional activity and life quality in sacroiliac joint injury patients.

Differential gene expression in foxtail millet during incompatible interaction with Uromyces setariae-italicae.

Foxtail millet (Setaria italica) is an important food and fodder grain crop that is grown for human consumption. Production of this species is affected by several plant diseases, such as rust. The cultivar Shilixiang has been identified as resistant to the foxtail millet rust pathogen, Uromyces setariae-italicae. In order to identify signaling pathways and genes related to the plant's defense mechanisms against rust, the Shilixiang cultivar was used to construct a digital gene expression (DGE) library during the interaction of foxtail millet with U. setariae-italicae. In this study, we determined the most abundant differentially expressed signaling pathways of up-regulated genes in foxtail millet and identified significantly up-regulated genes. Finally, quantitative real-time polymerase chain reaction (qRT-PCR) analysis was used to analyze the expression of nine selected genes, and the patterns observed agreed well with DGE analysis. Expression levels of the genes were also compared between a resistant cultivar Shilixiang and a susceptible cultivar Yugu-1, and the result indicated that expression level of Shilixiang is higher than that of Yugu-1. This study reveals the relatively comprehensive mechanisms of rust-responsive transcription in foxtail millet.
