'Zhizhang Guhong Chongcui' is a new cultivar of Prunus mume with cross-cultivar group characteristics. It has typical characteristics of cinnabar purple cultivar group and green calyx cultivar group. It has green calyx, white flower, and light purple xylem, but the mechanism remains unclear. In order to clarify the causes of its cross-cultivar group traits, the color phenotype, anthocyanin content and the expression levels of genes related to anthocyanin synthesis pathway of 'Zhizhang Guhong Chongcui', 'Yuxi Zhusha' and 'Yuxi Bian Lü'e' were determined. It was found that the red degree of petals, sepals and fresh xylem in branches was positively correlated with the total anthocyanin content. MYBɑ1, MYB1, and bHLH3 were the key transcription factor genes that affected the redness of the three cultivars of flowers and xylem. The transcription factors further promoted the high expression of structural genes F3'H, DFR, ANS and UFGT, thereby promoting the production of red traits. Combined with phenotype, anthocyanin content and qRT-PCR results, it was speculated that the white color of petals of 'Zhizhang Guhong Chongcui' were derived from the high expression of FLS, F3'5'H, LAR and ANR genes in other branches of cyanidin synthesis pathway, and the low expression of GST gene. The green color of sepals might be originated from the relatively low expression of F3'H, DFR and ANS genes. The red color of xylem might be derived from the high expression of ANS and UFGT genes. This study made a preliminary explanation for the characteristics of the cross-cultivar group of 'Zhizhang Guhong Chongcui', and provided a reference for molecular breeding of flower color and xylem color of Prunus mume.

Allergic rhinitis(AR) is a common chronic inflammatory disease of the upper respiratory tract. Due to its high prevalence, high recurrence rate, and lack of a definitive cure, it is considered a global health issue by the World Health Organization. The pathogenesis of AR is complex and mainly involves B cells, helper T cells, eosinophils, basophils, macrophages, as well as the cytokines and inflammatory mediators they secrete. Clinical treatment primarily focuses on inhibiting inflammatory mediators such as histamine and leukotrienes. In recent years, active ingredients of animal-derived traditional Chinese medicine(TCM) have shown unique advantages and potential in AR treatment thanks to their high safety, specificity, selectivity, and biopotency. This study systematically reviewed the therapeutic effects and mechanisms of active ingredients and mixed extracts from animal-derived TCM, such as bovine spleen, honeycomb, bee venom, maggot, and human placenta, which have been shown by modern pharmacological research to regulate the immune function in AR, providing a reference for further exploration and clinical development of active ingredients from animal-derived TCM. Studies have found that the active ingredients from animal-derived TCM can produce definite therapeutic effects in AR by modulating multiple immune balances in the body, with great clinical prospects. However, their mechanisms of action still require further investigation, and the quality control techniques for effective ingredients need to be improved. Currently, the research on active ingredients from animal-derived TCM in China has adopted an interactive system consisting of "traditional medical experience-based research, bioinformatics and artificial intelligence predictions, and validation and development through new experimental techniques". Based on this system, animal-derived TCM can combine modern scientific and technological means to maximize the therapeutic effects of active ingredients and serve the clinical application of AR in a more efficient and innovative manner.

Diversity-oriented synthesis is aimed to increase the chemical diversity of target natural products for extensive biological activity evaluation. Indole ring is an important functional group in a large number of drugs and other biologically active agents, and indole-containing natural products have been frequently isolated from marine sources in recent years. In this paper, a series of indole-containing marine natural hyrtioreticulin derivatives, including 19 new ones, were designed, synthesized through a key Pictet-Spengler reaction, and evaluated for their inflammation related activity. Compound 13b displayed the most promising activity by inhibiting TNF-α cytokine release with an inhibitory rate of 92% at a concentration of 20 μmol·L^-1. A preliminary structure-activity relationship analysis was also discussed. This research may throw light on the discovery of marine indole alkaloid derived anti-inflammatory drug leads.

Four new sesquiterpene quinone meroterpenoids, dysideanones F-G (1-2) and dysiherbols D-E (3-4), were isolated from the marine sponge Dysidea avara collected from the South China Sea. The new structures were elucidated by extensive analysis of spectroscopic data including HR-MS and 1D and 2D NMR spectra, and their absolute configurations were assigned by single-crystal X-ray diffraction and ECD calculations. Anti-inflammatory evaluation showed that dysiherbols D-E (3-4) exhibited moderate inhibitory activity on TNF-α-induced NF-κB activation in human HEK-293T cells with IC₅₀ values of 10.2 and 8.6 μmol·L^-1, respectively.

Ultraselective conventional transarterial chemoembolization (cTACE), defined as cTACE at the most distal portion of the subsubsegmental hepatic artery, is mainly performed for hepatocellular carcinoma (HCC) ≤5 cm. Distal advancement of a microcatheter enables injection of a larger volume of iodized oil into the portal vein in the limited area under non-physiological hemodynamics. As a result, the reversed portal flow into the tumor through the drainage route of the tumor that occurs when the hepatic artery is embolized is temporarily blocked. By adding gelatin sponge slurry embolization, both the hepatic artery and portal vein are embolized and not only complete necrosis of can be achieved. Ultraselective cTACE can cure small HCCs including less hypervascular tumor portions and replace surgical resection and radiofrequency ablation in selected patients.

PURPOSE: This descriptive research was on hand dermatitis in clinical nurses. Nurses often have a high rate of hand dermatitis with several factors associated with the dermatitis. The factors analyzed in this study included; general characteristics, work-related factors, hand washing, and allergies relate to hand dermatitis. METHODS: Data were collected from April to May 2016. The subjects were nurses who had worked 12 months or more in a University Hospital. They voluntarily gave their consent for the research. The Symptombased questionnaires were sent to 220 nurses and 199 responses were returned. Collected data were analyzed using frequency, percentage, mean, standard deviation, χ2-test, and logistic regression analysis using SPSS 23.0. RESULTS: Prevalence of dermatitis in nurses was 48.2%. Nurses who had worked for over three years were twice more likely to suffer hand dermatitis than nurses who had worked for 3 years or less (adjusted odds ratio [adj. OR]=1.97, p=.036). Nurses who used alcohol sponge swabs more than 20 times per shift were 2.5 times more likely to suffer hand dermatitis as compared to those who used them less times (adj. OR=2.51, p=.023). CONCLUSION: Results revealed that about a half of the clinical nurses suffered from hand dermatitis, hence it is crucial to find appropriate interventions for dermatitis prevention. This concern needs to be addressed especially in nurses who have more work experience and use more alcohol sponge swabs.

PURPOSE: Osteoarthritis (OA) is a commonly occurring illness without a definitive cure, at present. Long non-coding RNAs (lncRNAs) have been widely confirmed to be involved in the modulation of OA progression. This study aimed to investigate the role and mechanism of lncRNA H19 in OA. MATERIALS AND METHODS: Abundances of H19 and microRNA-130a (miR-130a) in lipopolysaccharide (LPS)-treated C28/I2 cells were measured by reverse-transcription quantitative PCR (RT-qPCR). CCK-8 and flow cytometry analyses were carried out to assess cell viability and apoptosis. Starbase online software was used to predict the putative binding sites between H19 and miR-130a. Luciferase reporter, RNA pull down, and RT-qPCR were performed to analyze the true interaction between H19 and miR-130a. RESULTS: A notably dose-dependent elevation of H19 levels was observed in LPS-treated C28/I2 cells. Knockdown of H19 ameliorated the injury of LPS-induced C28/I2 cells, reflected by induced viability, decreased apoptosis, and reduced inflammatory factor secretions. Moreover, H19 negatively regulated the expression of miR-130a via acting as a molecular sponge for miR-130a. The stimulatory effects of H19 on cell damage were abolished following the restoration of miR-130a. CONCLUSION: LncRNA H19 aggravated the injury of LPS-induced C28/I2 cells by sponging miR-130a, hinting a novel regulatory mechanism and a potential therapeutic target for OA.

STUDY DESIGN: Retrospective study. OBJECTIVES: This study was conducted to evaluate the effects of using an epidural steroid sponge for postoperative pain control in lumbar discectomy. SUMMARY OF LITERATURE REVIEW: There are many methods to control postoperative pain after lumbar discectomy, including opioid analgesics, epidural catheters, and epidural steroid Gelfoam sponges. MATERIALS AND METHODS: A total of 72 patients who underwent surgery between March 2011 and February 2014 were enrolled. Their average age was 54 years (range, 24–82 years). In group A (35 patients), Gelfoam was inserted after being soaked with a solution of 2% lidocaine (400 mg/20 mL; 1 vial) and dexamethasone (5 mg/mL; 1 ampoule). In group B (37 patients), it was inserted after soaking with normal saline. Postoperative pain was assessed by visual analogue scale (VAS) scores. Pain above 5 points was controlled by a narcotic analgesic agent, and the duration and number of postoperative interventions, the period of time before walking after the operation, and the period until the date of discharge after surgery were assessed and compared. The Mann-Whitney U test was used as a nonparametric method. P-values less than 0.05 were considered to indicate statistical significance. RESULTS: In group A, 15 patients did not require analgesics on the day of surgery. In 20 patients, no analgesics were needed on postoperative day (POD) 1. In group B, 8 patients on the day of surgery and 13 patients on POD 1 did not require analgesics. In group A, 26 patients were able to walk on the day of surgery, and all patients were able to walk on POD 1. In group B, 19 patients was able to walk on the day of surgery and all patients were able to walk on POD 1. The mean number of hospital days before discharge was 6.3 in group A and 8.2 in group B. CONCLUSIONS: By continuously releasing low doses of steroids into the epidural space, this technique provided satisfactory results for postoperative pain control.

Mushroom cultivation has gained increased attention in recent years. Currently, only four types of spawn, including sawdust spawn, grain spawn, liquid spawn, and stick spawn, are commonly available for mushroom cultivation. This limited spawn diversity has led to difficulty in selecting suitable inoculum materials in some cultivation. In this study, three small blocks of lignocellulosic agro-wastes and one block of a synthetic matrix were prepared as support for growing Pleurotus ostreatus in liquid medium. Mycelium-adsorbed blocks were then evaluated for their potential as block spawn for fructification. Our results indicated that the edible fungus was adsorbed and abundantly grew internally and externally on loofah sponge and synthetic polyurethane foam (PUF) supports and also has the ability to attach and grow on the surface of sugarcane bagasse and corncob supports. The mycelia of P. ostreatus adhered on corncob exhibited the highest metabolic activity, while those on the PUF showed the least activity. Mycelial extension rates of block spawns made of agro-waste materials were comparable to that of sawdust spawn, but the block spawn of PUF showed a significantly lower rate. No significant differences in cropping time and yield were observed among cultivations between experimental block spawns and sawdust spawns. Moreover, the corncob block spawn maintained its fruiting potential during an examined period of 6-month storage. The developed block spawn could be practically applied in mushroom cultivation.
