Fufang Zhenshu Tiaozhi (FTZ) has been widely used in clinical practice and proven to be effective against aging-induced osteoporosis in mice. This study aimed to explore the mechanism of FTZ against osteoclastogenesis and ovariectomized-induced (OVX) bone loss through the network pharmacology approach. The ingredients of FTZ were collected from the previous UPLC results, and their putative targets were obtained through multiple databases. Differentially expressed genes (DEGs) during osteoclastogenesis were identified through multi-microarrays analysis. The common genes between FTZ targets and DEGs were used to perform enrichment analyses through the clusterProfier package. The affinity between all FTZ compounds and enriched genes was validated by molecular docking. The effects of FTZ on osteoclastogenesis and bone resorption were evaluated by TRAP staining, bone resorption assay and RT-qPCR

The accuracy of gastric precancerous disease detection algorithms plays a pivotal role in the adjuvant treatment of gastric cancer patients. However, detection of gastric precancerous diseases are facing two thorny problems: i)the physiological stomach environment is complex, and the lesion site features are not obvious, which lead to low detection accuracy for inconspicuous targets; ii) since the feature scale of the lesion site varies in size, the recognition ability of existing detection models for targets of different sizes is poor due to their insensitivity to multi-scale features. To address these two challenging problems, we propose an efficient and lightweight object detection approach called ELOD for gastric precancerous diseases. At the heart of ELOD are a lightweight bottleneck attention module (LBAM) and an efficient spatial pyramid pooling (ESPP) module. LBAM is designed to strengthen important features while suppressing unimportant features of images, which enables networks to deeply learn obscure targets. ESPP is devised to extract multi-scale features, thereby enhancing the ability of networks to detect multi-scale targets. Moreover, we take advantage of the state-of-the-art object detection architecture YOLOv5s as the underlying platform to implement ELOD and assess the effectiveness of LBAM and ESPP. To evaluate the performance of ELOD, we conduct extensive experiments on a collected gastric precancerous disease dataset and two public datasets (i.e., a gastric polyp dataset and a blood cell dataset). In addition, we quantitatively validate the generality and versatility of LBAM and ESPP. Experimental results indicate that our approach achieves high prediction accuracy,while substantially streamlining network structure and considerably reducing the number of model parameters.

Background: Oral squamous cell carcinoma (OSCC) is an increasing disease worldwide that leads to lethal and deforming consequences. In OSCC, Fascin actin-bundling protein 1 (FSCN1) is identified as an oncogene involved in the tumorigenesis process. But the functions as well as potential mechanisms of FSCN1 in OSCC tumorigenesis process have not been reported so far. Methods: We used RNA sequencing to detect the expreesion of FSCN1 from 40 paired OSCC tissue specimens (Tumor) and neighboring noncancerous tissue. Further colony formation, CCK-8 as well as transwell assay was performed to demonstrate the role of FSCN1 in vitro. Moreover, glucose consumption was detected. Western blot was used to confirm the interaction of FSCN1, IRF4 and AKT. Results: FSCN1 was remarkably overexpressed in OSCC cell lines as well as tissues. Further colony formation, CCK-8 as well as transwell assay suggested that FSCN1 silencing remarkably dampened OSCC growth and migration. Detection of glycolytic metabolism showed that FSCN1 silence remarkably suppressed OSCC glycolysis. Following mechanism studies revealed that FSCN1 realized its functions in OSCC process partially through the interferon regulatory factor 4 (IRF4) and AKT activation. Conclusion: In conclusion, our study investigated the functions as well as the mechanisms of the FSCN1/IRF4/AKT pathway in OSCC progression. FSCN1 could act as a prospective biologic signature and therapeutic target molecule for OSCC.

The present work describes the relationship between volatile aroma components and flavours of Fenghuang Dancong tea. Volatile aroma components of five types of Fenghuang Dancong tea namely Baxian, Milanxiang, Yulanxiang, Guihuaxiang, and Yinhuaxiang were extracted by headspace solid-phase microextraction (HS-SPME), then analysed by gas chromatography-mass spectrometry (GC-MS) technique and gas chromatography olfactometry (GC-O) techniques. The GC-MS results showed that a total of 116 volatile components were detected, among which 21 (including alcohols, esters, olefins, aldehydes, ketones, and alkanes) were commonly detected in all types of tea. Based on GC-O analysis, 26 active ingredients that mainly contribute to grassy, sweet, floral, fruity, woody, and honey aromas were detected. Among these ingredients, four compounds including linalool oxide I, linalool, nerol, and neroli, which give floral, sweet, and honey aromas were abundant (with high aroma intensity) in all five types of tea. This suggests that these compounds are the main components contributing to the unique aroma of Fenghuang Dancong tea.

Objective In our previous study, tantalum nanoparticle (Ta-NPs) was demonstrated to promote osteoblast proliferation via autophagy induction, but the specific mechanism remains unclear. In the present study, we will explore the potential mechanism. Methods Ta-NPs was characterized by transmission electron microscopy, scanning electron microscopy, dynamic light scattering, and BET specific surface area test. MC3T3-E1 were treated with 0 or 20 μg/mL Ta-NPs with or without pretreatment with 10 μM LY294002, Triciribine, Rapamycin (PI3K/Akt/mTOR pathway inhibitors) for 1 h respectively. Western blotting was used to detect the expressions of pathway proteins and LC3B. CCK-8 assay was used to assess cell viability. Flow cytometry was used to detect apoptosis and cell cycle. Results After pretreatment with LY294002, Triciribine and Rapamycin, the p-Akt/Akt ratio of pathway protein in Triciribine and Rapamycin groups decreased (P P P P P Conclusion Pretreatment with Triciribine or Rapamycin has a greater effect on pathway protein Akt, cell cycle arrest, autophagy protein, and cell proliferation but with inconsistent magnitude, which may be inferred that the Akt/mTOR pathway, as well as its feedback loop, were more likely involved in these processes.

It was believed that when hydroxyapatite (HAP) was used to remediate heavy metal-contaminated soils, its effectiveness seemed likely to be affected by its particle size. In this study, a pot trial was conducted to evaluate the efficiency of two particle sizes of HAP: nanometer particle size of HAP (nHAP) and micrometer particle size of HAP (mHAP) induced metal immobilization in soils. Both mHAP and nHAP were assessed for their ability to reduce lead (Pb), zinc (Zn), copper (Cu), and chromium (Cr) bioavailability in an artificially metal-contaminated soil. The pakchoi (Brassica chinensisL.) uptake and soil sequential extraction method were used to determine the immobilization and bioavailability of Pb, Zn, Cu, and Cr. The results indicated that both mHAP and nHAP had significant effect on reducing the uptake of Pb, Zn, Cu, and Cr by pakchoi. Furthermore, both mHAP and nHAP were efficient in covering Pb, Zn, Cu, and Cr from nonresidual into residual forms. However, mHAP was superior to nHAP in immobilization of Pb, Zn, Cu, and Cr in metal-contaminated soil and reducing the Pb, Zn, Cu, and Cr utilized by pakchoi. The results suggested that mHAP had the better effect on remediation multiple metal-contaminated soils than nHAP and was more suitable for applying inin situremediation technology.

The effects of nanoscale particle hydroxyapatite (nHAP) on biomass, Cd uptake, the level of chlorophyll, vitamin C, malondialdehyde (MDA), and the activities of antioxidant enzymes, including SOD, CAT, and POD in pakchoi in Cd-contaminated soil, were evaluated by conducting pot experiment. Results showed that, by application of the 5 g·kg−1, 10 g·kg−1, 20 g·kg−1, and 30 g·kg−1nHAP in 10 mg·kg−1Cd-contaminated soil, the biomass of plant increased by 7.97%, 13.21%, 19.53%, and 20.23%, respectively. In addition, the reduction of Cd in shoots was 27.12%, 44.20%, 50.91%, and 62.36% compared to control samples. It was found that the supplement of the nHAP can increase the level of chlorophyll and vitamin C and decrease the level of MDA in plant shoots. Furthermore, the increment activities of SOD, CAT, and POD can be observed after addition of nHAP in Cd-contaminated soil. The results confirmed that nHAP can be applied to reduce the plant uptake of Cd and resist the Cd stress in the plant in Cd-contaminated soil.

"Analysis on land use coordination degree is instructive to land intensive use and land sustainable use. The coordination is established to analyze the land use coordination degree of Nanjing from 1999 to 2008; on the basis of this, coordination factors are analyzed by the multiple stepwise regression. The result shows that land use coordination degree in Nanjing has been in a rising trend in the recent ten years, but there is still a distance from the full coordination; we find that the main factors of land coordination use are population growth, economic development and the level of afforesting."
