    Abstract The male reproductive dysfunction accounts for 50% of infertile couples in the world. Cadmium (Cd) is one of the most harmful heavy metals to both the environment and inhabitants. Accumulating data suggest that Cd could cause male infertility. Sertoli cell (SC) is a somatic cell of testis and a key regulator of spermatogenesis by providing physical and nutritional support for developing sperm. Many studies showed that Cd induced dysfunction of SCs was directly related to male reproductive damage. However, the mechanism of SCs injury caused by Cd remains to be clarified. We found that Cd treatment caused a significant increase of apoptosis in SCs cells, accompanied by a marked increase in the production of ROS. These results were associated with the formation of mitochondria-containing autophagosomes and increased expression of LC3-II in vitro. Interestingly, our results showed that Cd did not promote but inhibited the fusion of mitochondria-containing autophagosomes with lysosomes by reducing the function of lysosomes. Together, this study provides insight into the negative effects of Cd, which interferes with autophagic flux and induces the apoptosis of SCs.

    Abstract Aim: MicroRNAs have been confirmed as vital regulators in gene expression, which could affect multiple cancer cell biological behaviors. This study aims to elucidate the molecular mechanism of miR-144-3p in lung cancer cellular proliferation and metastasis.
    Methods: MiR-144-3p expression in lung cancer tissues and cell lines was detected by qRT-PCR. HGF was predicted as the target gene of miR-144-3p using TargetScan and dual luciferase reporter assay. Immunohistochemistry and qRT-PCR were used to explore the impacts of HCF on lung cancer tissues and cell lines. Impacts of miR-144-3p and HGF on cancer cellular proliferation, migration and invasion were elucidated by CCK-8, Flow cytometry, Transwell invasion and Wound-healing assay. Moreover, nude mouse xenograft model was established to evaluate the effects of miR-144-3p on lung cancer cells.
    Results: MiR-144-3p exhibited a reduction in both lung cancer tissues and cell lines. HGF was a direct target of miR-144-3p. In contrast to the miR-144-3p expression level, HGF showed a higher level in lung cancer tissues and cell lines. Overexpression miR-144-3p suppressed A549 and NCI-H1299 cell proliferation and metastasis, whereas this was reversed by HGF. MiR-144-3p exhibited an inhibitory effect on A549 cell-induced tumor growth of nude mice.
    Conclusions: This study reveals miR-144-3p/HGF axis may be involved in the suppression of lung cancer cellular proliferation and development, and miR-144-3p may function as a potential therapeutic target in lung cancer treatment in the future.

    Abstract To date, in vivo investigations of polysaccharide’s pharmacokinetics are significantly restricted by the difficulty in their detection. This study was conducted to establish the quantitative determination of Lycium barbarum polysaccharides (LBPs) based on fluorescein isothiocyanate (FITC) pre-labeling and to investigate their tissue distribution in rat. We obtained the calibration curves linear over the range of 0–25µg/mL in rat tissue samples with correlation coefficients greater than 0.99. The inter-day and intra-day precisions (RSD, %) were within 15%, and the relative recovery ranged 95.2%–102.4%, with RSD range 1.48%–9.58%, indicating that this experiment was suitable for the determination of LBPs. The fluorescence intensity was measured after 24h storage at room temperature, 3 times of freeze-cycle and cryopreservation at –20 °C for 15 day, these results indicated that the stability of the samples was good. LBP-FITC was mainly absorbed by the small intestine and stomach, and mainly excreted in the urine through the kidney; this distinct difference in the tissue distribution of LBPs could be attributed to the size of these LBPs in relation to the pore sizes of the vascular beds in the kidney and liver. Results showed in this study enable us to comprehensively understand the biological effects of LBPs following its oral ingestion.

    Abstract Chuanminshen violaceum, as a food and folk medicine, is cultivated and grown only in China. Its polysaccharides play an important role in medicinal benefits. Herein, crude C. violaceum polysaccharides (CVPs) were purified to yield two polysaccharide fractions (CVPs-1-G and CVPs-2-G) using DEAE Cellulose-52 and Sephadex G-100 column chromatography. Structural analyses indicated that both CVPs-1-G and CVPs-2-G were glucans with average molecular weights of 8.1 kDa and 187.5 kDa, respectively. The main chain of the major component (CVPs-1-G) might be composed of (1 → 4)-linked α-Glcp, and the branched-chain might be an α-Glcp → 4)-α-D-Glcp-(1 → 6)-α-D-Glcp-(1 → 4)-α-D-Glcp, which connected to the main chain through the O-6 position of → 3,6)-α-D-Glcp-(1 →. In addition, CVPs-1-G displayed ABTS, DPPH, and hydroxyl radical scavenging activity, as well as competitive inhibitory activities of α-amylase and non-competitive inhibitory activities of lipase and pepsin. According to molecular docking, its inhibitory activity on digestive enzyme might be caused by hydrogen bond and hydrophobic interaction between them. Thus, CVPs exhibit strong potential for use in functional foods and pharmaceuticals.

    Abstract The effect of combined administration of calcium (Ca), iron (Fe), zinc (Zn), chrysanthemum flavonoids, and meso-2,3-dimercaptosuccinic acid (DMSA) on the treatment of lead (Pb) intoxication in mice was studied. One hundred ninety female mice (SPF level, aged 18-22 days) were randomly divided into two groups as experimental animals. Mice in group I (10 mice) served as normal control animals, and were administered deionized water containing 12.5 μL/L acetate acid for 6 weeks, whereas mice in group II (180 mice) were exposed to 0.1% (wt/vol) of lead acetate in deionized water for 6 weeks and served as experimental animals. After 6 weeks of successful modeling, 180 mice from group II (lead-exposed) were divided into 18 groups of 10 mice each, 16 of which were treated by the combined administration of Ca, Fe, Zn, chrysanthemum flavonoids, and DMSA by L

    Abstract Hepatocellular carcinoma (HCC) has an increasing incidence worldwide, and the global 5-year survival rate ranges from 5-30%. In China, HCC seriously threatens the nation's health; the incidence of HCC ranks fourth among all theriomas, and the mortality rate is the third highest worldwide. The main therapies for HCC are surgical treatment or liver transplantation; however, most patients with HCC will experience postoperative recurrence or metastasis, eventually resulting in mortality. As for advanced or unresectable HCC, the current appropriate treatment strategy is transarterial chemoembolization; however, limited therapeutic effect and natural or acquired drug resistance affect the efficacy of this approach. Previous studies have demonstrated that PD-L1 expression on host cells and myeloid cells plays an important role in PD-L1 blocked-mediated tumor regression. Thus, further research on programmed cell death protein 1 (PD-1) and programmed death-ligand 1 (PD-L1) is required. Countries including the United States, France, Britain and China have developed PD-1/PD-L1 blockers, including nivolumab, pembrolizumab, cemiplimab, atezolizumab, avelumab, durvalumab, toripalimab, sintilimab and camrelizumab. Notably, all of these blockers have therapeutic effect and influencing factors in HCC. Factors that influence the clinical outcome of PD-1 have also been discovered, such as inflammatory genes, specific receptors and signaling pathways. The discovery of these factors will help to identify novel methods, such as combination treatment, to decrease the influence of other factors on the efficacy of PD-1/PD-L1. Sorafenib and lenvatinib have been approved for first-line treatment for patients with advanced HCC. When first-line treatment frequently fails, pembrolizumab and ipilimumab plus nivolumab are used following sorafenib (but not lenvatinib) treatment in advanced HCC. Thus, tumor immunotherapy using PD-1/PD-L1 blockers exhibits promising outcomes for the treatment of HCC, and more novel PD-1/PD-L1 inhibitors are being developed to fight against this disease. The present review discusses the clinical results and influencing factors of PD-1/PD-L1 inhibitors in HCC to provide insight into the development and optimization of PD-1/PD-L1 inhibitors in the treatment of HCC.

    Abstract A high-performance gel permeation chromatography fluorescence detection (HPGPC-FD) method combined with fluorescein isothiocyanate (FITC) labeling was established for the microanalysis of L. barbarum polysaccharides (LBP). The calibration curves linear over the range of 0.2–20 µg/mL in rat plasma, and 0.25–500 μg/mL in urine and feces samples with correlation coefficients greater than 0.99. The inter-day and intra-day precisions (RSD, %) of the method were under 15% with the relative recovery ranging from 84.6% to 104.0% and the RSD ranging from 0.47% to 7.28%. The concentration–time curve of LBP-FITC in plasma following intragastric administration at 100, 50 and 25 mg/kg well fitted to a nonlinear model. LBP-FITC slowly eliminated from plasma according to the long half-lives (t₁/₂ = 31.39, 38.09, and 45.76 h, respectively) and mean retention times (MRT₀–ₜ = 18.38, 19.15 and 20.07 h, respectively; AUC₀–∞ = 230.49, 236.18 and 242.57 h, respectively) after administration of LBP-FITC at doses of 100, 50, and 25 mg/kg, respectively. After intragastric administration at 50 mg/kg for 72 h, the concentration of LBP-FITC in urine and feces was 0.09 ± 0.04% and 92.18 ± 3.61% respectively; the excretion rate of urine was the highest in 0–4 h period and decreased continuously in 4–24 h period. The excretion rate of feces was the highest in 4–10 h, 48.28 ± 9.349% in feces within 4–10 h, and decreased rapidly in 10–24 h. The present study showed that LBP was absorbed as its prototype and most proportion of LBP was excreted from feces, indicating a long time remaining in intestine.
