Preparation and application of KCC-1@ZIF-8 for the solid extraction of tetracycline with high adsorption capacity.

In this study, three different materials were prepared: dendritic fiber-type silica (KCC-1), zeolitic imidazolate framework-8 (ZIF-8), and a new composite material called KCC-1@ZIF-8. These materials were synthesized using microemulsion, stirring, and coating methods, respectively. The properties of the materials were characterized using various techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), TGA and X-ray diffraction (XRD). The results showed that KCC-1@ZIF-8 exhibited a significant increase in the BET surface area and pore size compared to the individual components KCC-1 and ZIF-8. These improved properties of the composite material were beneficial for enhancing the adsorption capacity. The effects of initial concentrations, solution pH and reaction time on the adsorption capacity were investigated. The adsorption kinetics and isothermal data of ZIF-8 and KCC-1@ZIF-8 fitted well with pseudo-second-order and Langmuir isotherm models. The results of adsorption thermodynamics show that the adsorption process is spontaneous and endothermic. KCC-1@ZIF-8 exhibited a very high adsorption capacity (751.46 mg g-1) at an initial TC hydrochloride concentration of 80 mg L-1 in an aqueous solution at 301.15 K, and the value was higher than that of ZIF-8 (549.80 mg g-1) under the same conditions. KCC-1 exhibited a relatively lower capacity (37.860 mg g-1). Based on these findings, KCC-1@ZIF-8 was considered a promising adsorbent for the treatment of wastewater contaminated with TC hydrochloride. Additionally, the composite material, when combined with high-performance liquid chromatography (HPLC), could be used as a solid-phase extraction adsorbent for the adsorption of TC hydrochloride in animal foodstuff samples. The calibration curves showed a linear range of 20-500 µg L-1, and the recovery rate ranged from 85.216% to 90.717%. No one has made adsorbents with this new structure before, and KCC-1@ZIF-8 possessed excellent adsorption properties, which make it a potential candidate for environmental remediation and analytical applications involving TC hydrochloride.

Dachsous cadherin related 1 (DCHS1) is a novel biomarker for immune infiltration and epithelial-mesenchymal transition in endometrial cancer via pan-cancer analysis.

BACKGROUND: Dachsous cadherin related 1 (DCHS1) is one of calcium-dependent adhesion membrane proteins and is mainly involved in the development of mammalian tissues. There is a lack of more detailed research on the biological function of DCHS1 in pan-cancer. MATERIALS AND METHODS: We evaluated the expression, the prognostic value, the diagnostic value and genomic alterations of DCHS1 by using the databases, including TCGA, UALCAN, HPA, GEPIA2.0 and GSCA. We employed the databases of UCSC, TIMER2.0, TISIDB, GSCA to analyze the association between DCHS1 expression and the immune microenvironment, stemness, TMB, MSI and anticancer drug sensitivity. BioGRID, STRING and GEPIA2.0 were used to perform protein interaction and functional enrichment analysis. Real-time quantitative PCR, CCK8, Transwell assay and Western blot were performed to determine the function of DCHS1 in UCEC. RESULTS: DCHS1 is differentially expressed in many cancers and its expression is significantly associated with tumor prognosis and diagnosis. DCHS1 expression was significantly correlated with the infiltration of cancer-associated fibroblasts (CAFs), Endothelial cell (ECs), and Hematopoietic stem cell in most cancers. In addition, DCHS1 was significantly associated with sensitivity to many antitumor drugs. Functional enrichment analysis revealed that DCHS1-related proteins were involved in Focal adhesion, Endometrial cancer and Wnt signaling pathway. GSEA results showed that DCHS1 was related to epithelial-mesenchymal transition (EMT) in many cancers. In vitro experiments in UCEC showed that DCHS1 regulated cell proliferation, migration and EMT. CONCLUSIONS: Our findings indicated that DCHS1 might be a novel prognostic and diagnostic biomarker and immunotherapy target, and plays an important role in the proliferation, migration and EMT in UCEC.

Peripapillary RNFL cross-sectional area and its association with other parameters in a Chinese population.

BACKGROUND: Quantitative analysis of retinal nerve fibers is important for the diagnosis and treatment of optic nerve diseases. Peripapillary retinal nerve fiber layer (RNFL) cross-sectional area may give a more accurate quantitative assessment of retinal nerve fibers than RNFL thickness but there have been no previous reports of the peripapillary RNFL cross-sectional area or other parameters. The purpose of the current study was to determine peripapillary RNFL cross-sectional area and its association with other factors in an adult Chinese population. METHODS: RNFL cross-sectional area was measured during peripapillary circular optical coherence tomography (OCT) scan with a diameter of 12° centered on the optic disc. Correlation between RNFL cross-sectional area and other parameters was evaluated by linear regression analysis in a cross-sectional study of an adult Chinese population. RESULTS: A total of 2404 eyes from 2404 subjects were examined. Multivariate linear regression analysis showed that larger RNFL cross-sectional area correlated with younger age (p < 0.001), female gender (p = 0.001), no history of diabetes (p = 0.012) and larger optic disc area (p < 0.001). CONCLUSIONS: Peripapillary RNFL cross-sectional area is correlated positively with optic disc area, suggesting that eyes with larger optic discs have thicker RNFL. Further studies are needed to confirm whether this correlation is due to differences in the numbers of retinal nerve fibers or other factors.

Reducing baseline toxicity in fishery product-related sediments from land to sea: Region-specific solutions are required.

Eastern China is a major producer of fishery products (including inland aquaculture, coastal mariculture, and coastal fishing products). The quality of the products is affected by hydrophobic organic contaminants (HOCs) in the sediments. Based on in-vitro luminescent bacterial assay, the baseline toxicity (BEQBio) of 56 common HOCs were assessed in the present study. Specifically, the BEQBio of sediments declined from land (31-400 mg/kg) to sea (9.1-270 mg/kg). However, the toxicity contribution explained by the HOCs increased gradually from land (0.70 %) to sea (10 %) using Iceberg Modeling. In the inland pond, current use HOCs (pyrethroid pesticide (PEs), organic tin (OTCs), and antibiotic) exhibited considerable concentrations, although their toxicity contribution was very small (0.076 %), thus more regulations on the use of HOCs should be proposed and further screening is needed to confirm the major toxicants. In coastal mariculture area, the toxicity contribution of current use HOCs further declined (0.010 %), whereas environmental background HOCs, such as polycyclic aromatic hydrocarbons (PAHs), became increasingly significant, with the contribution ratio increasing from 0.37 % to 2.4 %. To minimize the negative impacts of PAHs, optimization of energy structure in transportation and coastal industry is required. In the coastal fishing area, the phased-out persistent organic pollutants (POPs) remained a major concern, in terms of both concentration and toxicity contribution. The phased-out POPs explained 7.0 % of the toxic effects of the sediments from the coastal fishing area, due to historical residue, industrial emissions, and their high toxicities. For this reason, it is critical to improve the relevant emission regulations and standards, so as to eventually reduce the unintentional discharges of POPs.

Identification and characterization of the WOX Gene Family revealed two WUS Clade Members associated with embryo development in Cunninghamia lanceolata.

The WUSCHEL-related homeobox (WOX) gene family is vital for plant development and stress response. In this study, we conducted a comprehensive analysis of WOX genes in Cunninghamia lanceolata (C. lanceolata) and subsequently explored the potential roles of two ClWOX genes within the WUS clade. In total, six ClWOX genes were identified through a full-length transcriptome analysis. These genes, exhibiting conserved structural and functional motifs, were assigned to the ancient clade and Modern/WUS clade, respectively, through a phylogenetic analysis. Our expression analysis indicated that these ClWOX genes were highly expressed in the middle and late developmental stages of zygotic embryos in C. lanceolata. Moreover, only ClWOX5 and ClWOX6 within the Modern/WUS clade exhibited transcriptional activity, and their expressions were also induced in response to auxin and wounding. Overexpression of ClWOX5 and ClWOX6 in Arabidopsis caused a partially sterile phenotype, resulting in a very low seed setting rate. Transcriptomic analysis revealed that expressions of many embryo-defective (EMB) genes, phytohormone-related genes, and transcription factors (TFs) were dramatically altered in ClWOX5 and ClWOX6 transgenic plants, which suggested that ClWOX5 and ClWOX6 may play specific important roles in embryo development via complex gene networks. In addition, overexpression of ClWOX5 and ClWOX6 in leaf segments promoted shoot regeneration in tobacco, indicating that ClWOX5 and ClWOX6 can promote plant regeneration and could be used to improve genetic transformation. In conclusion, these results help to elucidate the function of the WOX gene and provide a valuable basis for future studies of the developmental regulation and applications of WOX genes in C. lanceolata.

Effects of rescue gloves on hand skin temperature and manual performance under local cold exposure / 环境与职业医学

Background Cold environments reduce work efficiency and increase the risk of frostbite. Objective To investigate the effects on cold protection and manual performance of rescue gloves in cold environments, and to preliminarily verify the feasibility of related quantitative characterization methods. Methods An experiment was conducted in a large and a small artificial climate chamber. 12 male right-handed university students were recruited. The experiment was divided into two parts, with 0-10 min as the baseline phase and 10-50 min as the test phase. Subjects sat quietly in a 16 ℃ large chamber, and hands were exposed to a small chamber at 0 ℃ either barely (control group) or with rescue gloves (experimental group). Skin temperatures of the five fingers (thumb, index finger, middle finger, ring finger, and little finger), as well as the dorsal and palm of the hands were measured. In addition, grip strength, manual dexterity, maximum finger flexion, and tactile sensitivity of the hands were measured as the indicators of manual performance. Results In the control group, cold-induced vasodilation occurred when the skin temperature of the five fingers were lowered to about 10 ℃. The maximum rate of change in skin temperature of the control group was in the following order: thumb＞index finger＞middle finger＞little finger＞ring finger＞dorsal＞palm, 165.7 ℃·h−1 in the thumb, 80.0 and 89.9 ℃·h−1 in the palm and dorsal respectively. In addition, the minimum skin temperature of the thumb was 6.6 ℃. Compared with the control group: the rate of change of skin temperature in the experimentalgroup decreased by about 50%; the grip strength decreased by 15% after wearing the rescue gloves (P<0.05); no differences in manual dexterity, maximum finger flexion, and tactile sensitivity were statistically significant (P>0.05). Conclusion This study proved that the rescue gloves improved the thermal comfort of hands while better balancing the effect of cold exposure on manual performance. The quantitative characterization methods can evaluate the protective performance and manual performance of the rescue gloves, which provides a reliable theoretical foundation and reference basis for further experiments.

Compared with cisplatin group， the inhibitory rate of cell proliferation， apoptotic rate and cleaved-caspase-3/ caspase-3 were further increased in cisplatin+ligustilide low-， medium- and high-concentration groups， while scratch healing rate， the number of invasive cells， the mRNA expressions of YAP and TAZ， and the protein expressions of YAP， TAZ， MMP2 and Ki67 were further decreased， in a dose-dependent manner （P＜0.05）. CONCLUSIONS Ligustilide can increase the sensitivity of drug-resistant cervical cancer cells to cisplatin by inhibiting Hippo-YAP signaling pathway.

Magnesium promotes vascularization and osseointegration in diabetic states / 国际口腔科学杂志·英文版

Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues. Magnesium has been proved to promote bone healing under normal conditions. Here, we elucidate the mechanism by which Mg2+ promotes angiogenesis and osseointegration in diabetic status. We generated a diabetic mice model and demonstrated the alveolar bone healing was compromised, with significantly decreased angiogenesis. We then developed Mg-coating implants with hydrothermal synthesis. These implants successfully improved the vascularization and osseointegration in diabetic status. Mechanically, Mg2+ promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nucleation of nuclear factor erythroid 2-related factor 2 (Nrf2) by up-regulating the expression of sestrin 2 (SESN2) in endothelial cells, thus reducing the elevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia. Altogether, our data suggested that Mg2+ promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondrial metabolism.

Mechanism and treatment of mucous hypersecretion in chronic obstructive pulmonary disease / 中国临床药理学与治疗学

Airway mucus hypersecretion is one of the important pathophysiological and clinical manifestations of chronic obstructive pulmonary disease. It has been reported in the literature that COPD patients with chronic airway mucus hypersecretion have more frequent acute exacerbations, more severe lung function decline, and higher hospitalizations and mortality. Therefore, it is particularly critical to understand the pathogenesis of hypersecretion of mucus in chronic obstructive pulmonary disease and find out effective treatment. This article focuses on the structure, significance of airway mucus and the mechanism of hypersecretion of mucus in chronic obstructive pulmonary disease (COPD). In addition, we also summarized drug and non-drug therapy for chronic airway mucus hypersecretion in this article. Drug therapy includes traditional drug therapy, some new targeted drug therapy for pathogenesis and traditional Chinese medicine therapy, and non-drug therapy includes smoking cessation, physical therapy and bronchos-copy therapy. We hope that it will provide new ideas and directions for the treatment of mucus hypersecretion in COPD patients.

Prevention and treatment of high-risk human papilloma virus infection from the perspective of "prevention treatment of disease" based on the theory of "circular flow of Qi" / 国际中医中药杂志

The occurrence of cervical cancer in women is closely related to high-risk HPV infection, and timely and effective interruption of high-risk HPV infection is of great significance to prevent the occurrence of cervical cancer. Huang Yuanyou's theory of "circular flow of Qi" emphasizes on the harmonization of the overall Qi flow, which can explain the physiopathology of women. The occurrence of high-risk HPV infection is related to the loss of spleen and earth transportation in the middle Jiao, poor circulation of Qi, and the low resistance of the body to evil, resulting in the malfunctioning of clear and turbid. Based on the theory of "circular flow of Qi" combined with the idea of "prevention treatment of disease", the author proposes to "prevent the disease before it occurs, regulate the middle earth to preserve the correct Qi" and "prevent the disease before it occurs". The principles of prevention and treatment of high-risk HPV infection are "prevent before the disease, regulate the middle earth to preserve the righteousness", "promote and descend to dispel the poisonous evil", and "prevent recurrence after the disease, balance yin and yang and harmonize Qi and blood", in order to provide reference for clinical treatment.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine：Fibromyalgia Syndrome / 中国实验方剂学杂志

Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

Sinomenine effectively inhibits interleukin-1beta-induced apoptosis in nucleus pulposus cells / 中国组织工程研究

BACKGROUND:Intervertebral disc degeneration is the basis of spinal degenerative diseases;however,there is no effective treatment. OBJECTIVE:To investigate whether sinomenine can inhibit interleukin-1β-induced apoptosis in nucleus pulposus cells and its molecular mechanism. METHODS:Rat nucleus pulposus cells were cultured in vitro by trypsin combined with type II collagenase digestion,and the cell growth curve was plotted.An appropriate sinomenine concentration was determined using the cell counting kit-8 kit.Nucleus pulposus cells were divided into control group,sinomenine group,interleukin-1β group,sinomenine+interleukin-1β group,zinc protoporphyrin group,zinc protoporphyrin+sinomenine group,zinc protoporphyrin+interleukin-1β group,and sinomenine+zinc protoporphyrin+interleukin-1β group.Proliferative activity,reactive oxygen species content,apoptosis rate,and heme oxygenase-1 expression in nucleus pulposus cells were detected. RESULTS AND CONCLUSION:The rat nucleus pulposus cells cultured in vitro were polygonal,triangular,and short wedge-shaped,and the cell growth showed an"S"curve.The cells grew slowly in the first 3 days of culture,rapidly in 4-6 days,and slowly again in 7-8 days.The cells then entered the"platform stage"where the number of cells no longer increased.The proliferative activity of myeloid cells showed no significant changes when the concentration of sinomenine was≤80 μmol/L(P>0.05).Interleukin-1β significantly reduced the proliferative activity of nucleus pulposus cells,increased the content of reactive oxygen species and led to apoptosis(P<0.01).Sinomenine intervention not only promoted heme oxygenase-1 expression(P<0.05)but also inhibited interleukin-1β-induced decrease in proliferative activity and increase in reactive oxygen species content and apoptosis rate in nucleus pulposus cells(P<0.05).These effects could be reversed by zinc protoporphyrin(P<0.01).
