Identification and biological characterization of pathogen causing black spot of Pseudostellaria heterophylla in Fujian province / 中国中药杂志

In Zherong county, Fujian province, the black spot of Pseudostellaria heterophylla often breaks out in the rainy season from April to June every year. As one of the main leaf diseases of P. heterophylla, black spot seriously affects the yield and quality of the medicinal material. To identify and characterize the pathogens causing black spot, we isolated the pathogens, identified them as a species of Alternaria according to Koch's postulates, and then tested their pathogenicity and biological characteristics. The results showed that the pathogens causing P. heterophylla black spot were A. gaisen, as evidenced by the similar colony morphology, spore characteristics, sporulation phenotype, and the same clade with A. gaisen on the phylogenetic tree(the maximum likelihood support rate of 100% and the Bayesian posterior probability of 1.00) built based on the tandem sequences of ITS, tef1, gapdh, endoPG, Alta1, OPA10-2, and KOG1077. The optimum conditions for mycelial growth of the pathogen were 25 ℃, pH 5-8, and 24 h dark culture. The lethal conditions for mycelia and spores were both treatment at 50 ℃ for 10 min. We reported for the first time the A. gaisen-caused black spot of P. heterophylla. The results could provide a theoretical basis for the diagnosis and control of P. heterophylla leaf spot diseases.

Identification and biological characteristics of violet root rot pathogen of Pseudostellaria heterophylla in Fujian province / 中国中药杂志

Violet root rot is one of the main root diseases in the production process of Pseudostellaria heterophylla. To clarify the pathogenic species that cause the violet root rot of P. heterophylla in Fujian province, the roots and the sclerotia with violet root rot symptoms were collected from the main producing areas of P. heterophylla(Fujian province) from 2017 to 2021, and the pathogens were isolated by tissue separation method and identified by morphology and multi-gene phylogenetic analysis. Additionally, the biological characteristics of the pathogens were studied and the fungicides were determined. The results showed that 78 strains of violet root rot were isolated from the collected root samples, which belonged to one type after preliminary morphological identification. Two represen-tative strains were selected from the pathogens for multi-gene phylogenetic analysis, and they were clustered with Helicobasidium mompa together. The suitable culture conditions for the mycelium were OA medium, 25 ℃, pH 6, and ammonium oxalate as the nitrogen source. The lethal temperature of the mycelium was 50 ℃ for 10 minutes. Moreover, 99.1% propiconazole and 98.7% azoxystrobin had the optimal bacteriostatic effect, and the concentrations with the 50% bacteriostatic rate were 16.85 and 12.24 μg·mL~(-1), respectively. On the basis of the above results, the pathogen causing violet root rot of P. heterophylla in Fujian province was H. mompa. The medium type, growth temperature, pH value, nitrogen source, etc. had significant effect on the growth of mycelium.

AIM: To systematically evaluate the effects of femtosecond laser-assisted cataract surgery and conventional ultrasound cataract surgery(CUCS)on corneal endothelial cells.METHODS: Databases such as PubMed, Cochrane Library, Web of Science, Embase, CNKI, CBM, VIP and WanFang Data were searched for randomized controlled trials(RCT)from the establishment of the database to November 2021 on the effects of femtosecond laser cataract surgery and conventional ultrasound cataract surgery on corneal endothelial cells. Language is limited to Chinese or English. The literatures were evaluated by the Manual of Systematic Evaluation of Cochrane Interventions and the modified Jadad Scale. Stata 15.0 software was used for statistical analysis.RESULTS: A total of 13 RCT were included, including 1 446 eyes in the FLACS group and 1 472 eyes in the CUCS group. The Meta-analysis results showed that the cumulative dissipated energy(CDE)in FLACS group was obviously lower than that in CUCS group [WMD=-3.84, 95%CI (-6.30, -1.38), P=0.002]. The effective phacoemulsification time(EPT)in the FLACS group was obviously lower than that in the CUCS group [WMD=-3.03, 95%CI(-4.00, -2.05), P<0.001]. The density of corneal endothelial cells in both the FLACS group after surgery at 1 and 3mo was higher than that in CUCS group [WMD=121.76, 95%CI(79.31, 164.20), P<0.001; WMD=76.04, 95%CI(19.25, 132.82), P=0.009]; The thickness of the central cornea in the CUCS group was significantly thicker than that in the FLACS group at 1wk after the surgery [WMD=-9.89, 95%CI (-18.60, -1.18), P=0.026]; The incidence of postoperative corneal edema in the FLACS group was less than that in the CUCS group [RR=0.46, 95%CI(0.32, 0.66), P<0.001]. There were no differences in the percentage of hexagonal cells and coefficient of variation of corneal endothelial cells between the two groups.CONCLUSION: Compared with conventional ultrasound cataract surgery, femtosecond assisted cataract surgery can significantly reduce the phacoemulsification energy and the duration of the phacoemulsification energy, and significantly reduce the loss of corneal endothelial cells in the early postoperative period, while reducing the occurrence of postoperative corneal edema.

Network pharmacology study of flavone extracts of Silybum marianum in the treatment of nonalcoholic fatty liver disease / 药学学报

To investigate the therapeutic effect and molecular mechanism of the main flavonoid components of Silybum marianum (S. marianum) on nonalcoholic fatty liver disease (NAFLD), we identified nine flavonoids in S. marianum through TCMSP, PubChem database and corresponding literatures. The potential therapeutic targets of NAFLD were predicted by SwissTargetPrediction, GeneCards and Venny 2.1.0 platform, while the protein-protein interaction (PPI) network of potential targets was analyzed using String platform and Cytoscape software. Then GO and KEGG pathway enrichment analysis were performed using David 6.8 database, followed by molecular docking verification using AutoDock software. In vitro, components with higher degree value in the "components-targets-pathway" network were chosen for further analysis. L02 cells were used to establish lipid accumulation model and treated with different components. Furthermore, the effects of four pure active compounds from S. marianum on lipid accumulation in hepatocytes were analyzed by oil red O staining. The results showed that the main nine flavonoids extracted from S. marianum contained 24 potential NAFLD targets. Several critical pathways closely related to NAFLD process were identified by GO and KEGG enrichment analysis, including phosphatidylinositol 3-kinase-protein kinase B (PI3K-Akt) pathway, type 2 diabetes pathway, tumor necrosis factor (TNF) pathway and insulin resistance pathway. The results of molecular docking further indicated that the core components displayed strong binding abilities with key targets respectively, and silandrin showed better binding activity as compared to other components. The results obtained from L02 cells showed that the lipid accumulation was reduced by treatment with isosilybin A, isosilybin B, silydianin and silychristin, while the activity of isosilybin B was better than that of isosilybin A. Taken together, we concluded that the main flavone components of S. marianum could improve lipid accumulation through multiple signaling pathway in hepatocytes, and this could be a potential new strategy for the treatment of NAFLD.

Physalin B reduces Aβ secretion through down-regulation of BACE1 expression by activating FoxO1 and inhibiting STAT3 phosphorylation / 中国天然药物

Physalin B (PB), one of the major active steroidal constituents of Solanaceae Physalis plants, has a wide variety of biological activities. We found that PB significantly down-regulated β-amyloid (Aβ) secretion in N2a/APPsw cells. However, the underlying mechanisms are not well understood. In the current study, we investigated the changes in key enzymes involved in β-amyloid precursor protein (APP) metabolism and other APP metabolites by treating N2a/APPsw cells with PB at different concentrations. The results indicated that PB reduced Aβ secretion, which was caused by down-regulation of β-secretase (BACE1) expression, as indicated at both the protein and mRNA levels. Further research revealed that PB regulated BACE1 expression by inducing the activation of forkhead box O1 (FoxO1) and inhibiting the phosphorylation of signal transducer and activator of transcription 3 (STAT3). In addition, the effect of PB on BACE1 expression and Aβ secretion was reversed by treatment with FoxO1 siRNA and STAT3 antagonist S3I-201. In conclusion, these data demonstrated that PB can effectively down-regulate the expression of BACE1 to reduce Aβsecretion by activating the expression of FoxO1 and inhibiting the phosphorylation of STAT3.

Multi-slice spiral CT imaging anatomical study of the Milligan's septum / 解剖学报

Objective: To study the CT manifestations of Milligan's septum(MS). Methods: The pelvic CT images of 172 patients with non-anal disorders were retrospectively analyzed, based on the 1.5 mm thin-slice reconstruction. The CT manifestations of their MS and adjacent fat tissue were observed using multiplanar reconstruction and appropriate window technique. Results: The density of upper fat tissue adjacent to MS was lower than that of lower fat tissue, and the difference in CT values between them was statistically significant (P<0.05). Compared with females, the density of fat tissue in the lower anal subcutaneous space was much higher in males (38.37% vs 88.37%), even to the extent that the difference between upper and lower fat tissues could be visually identified; the difference between genders was a statistically significant (P<0.05). The CT direct visualization rate of MS was about 23.26%; the soft tissue density shadows, which could be divided into the relatively symmetrically whole-course linear type, partially linear type and branched type, started from the junction of the subcutaneous and superficial parts of external anal sphincter and travelled to the ischial tuberosity. According to the statistical result of the maximum thickness collected from those showing direct visualization, the average values of left and right sides were (2.50±0.46) mm and(2.89±0.78) mm, and the average values of both sides in males and females were(2.71±0.43) mm and(2.69 ±0.44)mm, respectively. Conclusion: Milligan's septum can be located according to the density difference between the fat tissues in the upper ischiorectal space and the lower anal subcutaneous space, while it can also be directly visualized on CT images in some cases.

Immune regulation by protein ubiquitination: roles of the E3 ligases VHL and Itch

Protein ubiquitination is an important means of post-translational modification which plays an essential role in the regulation of various aspects of leukocyte development and function. The specificity of ubiquitin tagging to a protein substrate is determined by E3 ubiquitin ligases via defined E3-substrate interactions. In this review, we will focus on two E3 ligases, VHL and Itch, to discuss the latest progress in understanding their roles in the differentiation and function of CD4 T helper cell subsets, the stability of regulatory T cells, effector function of CD8 T cells, as well as the development and maturation of innate lymphoid cells. The biological implications of these E3 ubiquitin ligases will be highlighted in the context of normal and dysregulated immune responses including the control of homeostasis, inflammation, auto-immune responses and anti-tumor immunity. Further elucidation of the ubiquitin system in immune cells will help in the design of new therapeutic interventions for human immunological diseases and cancer.

A preliminary analysis on using traditional Chinese medicine differentiation thinking for treatment of pancreatic pseudocyst induced by severe acute pancreatitis / 中国中西医结合急救杂志

Pancreatic pseudocyst (PPC) is one of the common peri-pancreatic complications of severe acute pancreatitis (SAP), and it belongs to the category of Zhengjiajiju in traditional Chinese medicine (TCM). Clinically, skilled use of surgical minimally invasive means combined with TCM treatment has remarkable advantages in promoting the rate of cystic absorption, reducing the surgical intervention rate, lowering the incidence of complications, etc. TCM syndrome differentiation treatment for SAP complicated with PPC can start from Shaoyang meridian lesions, and the treatment of Shaoyang liver and gallbladder visceral disease can be taken as an example. The clinical therapeutic result is significant by using soothing liver and normalizing gallbladder function, removing stagnancy and obstruction of the fu-organs and invigorating blood circulation and softening hard mass as the basic TCM rules to dialectically use the PPC basic prescription, locally accompanying with external therapy. The discussion of this article focuses on the experience of using TCM syndrome differentiation for treatment of patients with PPC induced by SAP.
