β-pinene is a monoterpene isolated from turpentine oil and numerous other plants’ essential oils, which has a broad spectrum of biological activities. In the current work, six novel β-pinene quaternary ammonium (β-PQA) salts were synthesized and evaluated in vitro for their antifungal, antibacterial and anticancer activities. The in vitro assay results revealed that compounds 4a and 4b presented remarkable antimicrobial activity against the tested fungi and bacteria. In particular, compound 4a showed excellent activities against F. oxysporum f.sp. niveum, P. nicotianae var.nicotianae, R. solani, D. pinea and Fusicoccumaesculi, with EC50 values of 4.50, 10.92, 9.45, 10.82 and 6.34 μg/mL, respectively. Moreover, compound 4a showed the best antibacterial action against E. coli, P. aeruginosa, S. aureus and B. subtilis, with MIC at 2.5, 0.625, 1.25 and 1.25 μg/mL, respectively. The anticancer activity results demonstrated that compounds 4a, 4b, 4c and 4f exhibited remarkable activity against HCT-116 and MCF-7 cell lines, with IC50 values ranged from 1.10 to 25.54 μM. Notably, the compound 4c displayed the strongest cytotoxicity against HCT-116 and MCF-7 cell lines, with the IC50 values of 1.10 and 2.46 μM, respectively. Furthermore, preliminary antimicrobial mechanistic studies revealed that compound 4a might cause mycelium abnormalities of microbial, cell membrane permeability changes and inhibition of the activity of ATP. Altogether, these findings open interesting perspectives to the application of β-PQA salts as a novel leading structure for the development of effective antimicrobial and anticancer agents.

Mesoporous nanocrystalline tetragonal zirconias were successfully synthesized through a hydrothermal method using a novel bioresource-derived quaternary ammonium salt, dehydroabietyltrimethyl ammonium bromine (DTAB), as a templating agent. The templating agent provides a surface area (242.02 m2/g), high pore volume (0.53 cm3/g), and large average pore diameter (7.65 nm), which suggests that DTAB is a good candidate for mesostructure synthesis. The hydrothermal treatments give the materials improved thermal stabilities because of the generation of tetragonal nanocrystallites that are more stable than the bulk amorphous ones in the hydrothermal process. However, because of the absence of stabilizers, the sizes of the crystallites of the as-synthesized sample increase gradually with increasing calcination temperature. As the crystalline size of the sample rises to 25 nm, the nanocrystallites become too large to integrate well together, causing the well-organized mesostructure to collapse.

Objectives: This study aimed to understand the resilience experiences in patients with inflammatory bowel disease (IBD) and develop the resilience framework for them., Methods: Semistructured interviews were conducted with 15 patients with IBD who were purposefully recruited from the gastroenterology department of two hospitals in Jiangsu, China to gain diversity in the demographic and clinical characteristics. The data were analyzed using a directed content analysis approach based on the Kumpfer's resilience framework., Results: The resilience framework for patients with IBD was formed from the analysis. This framework was composed of four themes, as follows: (1) complicated factors in the environment, (2) change the environment into a protective one, (3) personality traits, and (4) resilience-related coping., Conclusions: The resilience framework for patients with IBD can effectively characterize the resilience experience of patients during the disease and assist healthcare professionals to understand how patients recover from the disease. More quantitative studies are needed to further explore the influencing factors of resilience and improve resilience in patient with inflammatory Bowel Disease.

To study the breeding system and pollination characteristics of Gleditsia sinensis, we observed the development of flower development and the processing of pollination, and determined the pollen viability and stigma acceptability by TTC and benzidine-hydrogen peroxide method and detected its breeding system using OCI value, P/O ratio and artificial pollination.The results showed that: ①G. sinensis are racemes, divided into bisexual inflorescences (only a small amount of inactive pollen) and male inflorescences (occasionally a few bisexual flowers), flowers hermaphrodite. ②Male flowers had the strongest pollen activity 4 h after flowering; the stigma receptivity of bisexual was the highest at 1 h after flowering, and pollination was the best in this time. ③The pollen tube had a few elongation when the bisexual flower is half-opened. The number of pollen tube and length significantly increased when blooming. The flower reaches the ovary and even enters the ovule to complete the fertilization. ④When the OCI=4 and P/O=11 684, it means that the breeding system was facultative, outcrossing, and requiring pollinators based on the results of the bagging experiment.There was parthenogenesis. ⑤The characteristics of saponin pollination were wind pollination and insect vector pollination, and pollinators were initially identified as Apis mellifera ligustica. All these results provides a theoretical and technical foundation for the new germplasm of G. sinensis., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)

To study morphological characteristics change of the development process and quercetin and polyphenols of accumulation dynamic of the spines of Gleditsia sinensis, measure and compare morphological indexes using Vernier caliper, ruler and balance, calibrate and analysis quercetin and polyphenols content using HPLC and colorimetric method. The spines of G. sinensis development process is divided into formation period (the beginning of August to the beginning of November), dormant period (the beginning of November to the end of March in the following year), germination period (the end of March to the middle of April), fast growth period (the middle of April to the middle of August), browning period (the middle of August to the end of August) and mature period (the beginning of September to the end of December). Formation period the spines primordium divides and forms the scale bubs; dormant period the scale bubs are in a dormant state; germination period the bubs scales fall off, spines primordium began to development; fast growth period rapid growth to maximum; browning period browning from the tip and browns until the whole becomes brown; mature period The early stage of maturity is full of luster, gradually the color deepened and the luster faded. The accumulation of quercetin was gradually decreasing after increasing. The total polyphenol accumulation was significantly decreased and then gradually increased, decreased finally. The content of quercetin was increased from 0.000 4%-0.002 6%, and the polyphenol content decreased from 0.761 9%-0.049 1% and then slowly increased to 0.286 9% in the fast growth period.The quercetin continuous increase to 0.004 3% and total polyphenol increased to 0.421 6% in the browning period. In the mature period, the quercetin content significantly decreased after reaching 0.009 6% in September, and the polyphenols content decreased after reaching 0.723 5% in October. Using principal component analysis results: September first, October 2nd, November 3rd. The morphological characteristics change of the development process and quercetin and polyphenols accumulation were determined. The development process is divided into six periods, the best harvest time is the early stage of mature period. Provide theoretical support for the utilization of the spines of G. sinensis and cultivation techniques of high yield., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)
