Objective :
To investigate the effects of cinnamaldehyde(CA) on the growth, metastasis and apoptosis of human endometriosis(EMs) cells and to explore whether the mechanism is related to ribosomal protein S7(RPS7) expression.
Methods :
Endometriosis cells were divided into control group, CA group, sh-NC group, CA+sh-RPS7 group. Effects of CA on cell growth in human endometriotic cells were determined using Cell Counting Kit-8(CCK-8) and colony formation assay. Effects of CA on cell metastasis were performed by motility assay and Transwell assay. Effects of CA on cell apoptosis were evaluated by Hoechst 33258 staining and flow cytometry. Meanwhile, the levels of PCNA, E-cadherin, Vimentin, Bax and Bcl-2 were evaluated using Western blot in human endometriotic cells with treatment CA. The expression of RPS7 was detected by qRT-PCR and Western blot assay. The RPS7 overexpression of human endometriotic cells was established by cell transfection. CA-mediated effects on cell proliferation and apoptosis were determined by CCK-8 assay and flow cytometry in human endometriotic cells with RPS7 overexpression.
Results :
CA repressed cell growth as well as down-regulated PCNA. The half inhibitory concentration(IC50) value was 53.60 μmol/L after 24 h treatment, and colony formation rate was 25.32%. Additionally, CA inhibited metastasis which was associated with downregulated Vimentin and upregulated E-cadherin. The relative migration rates were 35% and 29% as well as invasion rate was 40%. Further, CA induced apoptosis by cell cycle G2/M phase arrest and cell apoptosis rate was 25.1%, which related to the up-regulation of of Bax and the down-regulation of Bcl-2. CA inhibited the expression of RPS7 and overexpression of RPS7 promoted cell proliferation and suppressed apoptosis in CA-mediated cells.
Conclusion
CA inhibits cell growth, metastasis, and induces cell apoptosis by downregulating the expression of RPS7.

Familial hyperaldosteronism type Ⅲ(FH-Ⅲ) is extremely rare, and there are no reported cases in China. Herein, we reported two cases with FH Ⅲ, both of which presented with severe hypertension and hypokalemia in their early childhood. One patient had significantly enlarged adrenal glands and developed clinical manifestations of Cushing′s syndrome at the age of 20. Complete relief of symptoms was achieved after bilateral adrenalectomy. The other case had normal adrenal imaging, and with spironolactone treatment, blood pressure and potassium levels were well-controlled. Both cases had germline mutation of KCNJ5 gene which were c. 433G>C(p.Glu145Gln) and c. 452G>A(p.Gly151Glu), respectively.

ObjectiveTo explore the possible mechanism of Bimin Formula (鼻敏方) in treating lung-spleen qi deficiency syndrome of allergic rhinitis (AR) with high mucin secretion. MethodsThirty-four SD rats were randomly divided into a blank group (8 rats), a model group (8 rats), a low-dose Bimin Formula group (8 rats), and a high-dose Bimin Formula group (10 rats). Except for the blank group, the other groups were subjected to AR lung-spleen qi deficiency rat models induced by smoking, gavage of Ginkgo biloba leaf extract, and ovalbumin. After modeling, rats in the low- and high-dose Bimin Formula groups were given Bimin Formula concentrate (concentration of 2.16 g/ml) by gavage at doses of 1.08 g/100 g and 2.16 g/100 g, respectively, while rats in the model group were given 0.5 ml/100 g of normal saline by gavage, once daily for 28 days; the blank group was not intervened. Behavioral assessments were performed after intervention. ELISA was used to detect the levels of peripheral blood total immunoglobulin E (IgE). HE staining was used to observe the pathological changes of nasal mucosa epithelium in rats, while immunohistochemistry was used to detect the expression of transmembrane protein 16A (TMEM16A) and mucin 5AC (MUC5AC) protein in nasal mucosa. Western Blot was used to detect the expression of nuclear factor kappa B (NF-κB) protein, and RT-PCR was used to detect the expression of TMEM16A, MUC5AC, and NF-κB mRNA in nasal mucosa. ResultsHE staining showed that the nasal mucosa epithelial cell structure in the blank group was intact without shedding, swelling, or necrosis; the nasal mucosa epithelial tissue of rats in the model group was thickened and partially shed, with infiltration of eosinophils and lymphocytes visible; the pathological changes in nasal mucosa tissue of rats in the high- and low-dose Bimin Formulagroups were improved, and more improvement was showen in the high-dose group. Compared with those in the blank group, the behavioral scores and peripheral blood total IgE levels of rats in the model group significantly increased, as well as the expression of TMEM16A, MUC5AC, and NF-κB proteins and mRNA in nasal mucosa (P<0.05 or P<0.01). Compared with those in the model group, the behavioral scores and peripheral blood total IgE levels of rats in the high-dose Bimin Formula group decreased, and the expression of TMEM16A, MUC5AC, and NF-κB proteins and mRNA in nasal mucosaalso decreased (P<0.05 or P<0.01); the behavioral scores and peripheral blood total IgE levels of rats in the low-dose Bimin Formula group were reduced, and the expression of TMEM16A and MUC5AC proteins and mRNA in nasal mucosa, as well as the expression of NF-κB protein decreased (P<0.05 or P<0.01), but the difference in NF-κB mRNA expression was not statistically significant (P>0.05). Compared with the low-dose Bimin Formula group, the expression of NF-κB protein in the high-dose group decreased (P<0.01). ConclusionBimin Formula may improve the symptoms and high mucus secretion of AR lung-spleen qi deficiency by regulating the TMEM16A/NF-κB/MUC5AC signaling pathway in nasalmucosa.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Based on our previous work, the study herein designed and synthesized eight glycoconjugates of natural product harmine (14a-14h)by introducing a cyclohexylmethyloxyl group at its C7 position and coupling a methyl-2-amino-β-D-glucopyranoside to the N9 position through different lengths of alkyl chains.In vitro anti-tumor activity screening and structure-activity relationship studies showed that the antitumor activity of the conjugates increased with the lengthening of the alkyl chain in the linker.Compound 14h exhibited significantly better proliferative inhibitory activity against MDA-MB-231 breast cancer cells than harmine.As compared to harmine, the introduction of the carbohydrate moiety improved the water solubility of compound 14h and enhanced its tumor cell selectivity through the Warburg effect.Mechanism of action studies revealed that compound 14h induced apoptosis and G0/G1 cell cycle arrest in MDA-MB-231 cells, and inhibited tumor cell migration by interfering with epithelial-mesenchymal transition process.This study provides a new approach for the development of antitumor drugs based on harmine.

Objective:To evaluate the relationship between B-cell lymphoma/adenovirus E1B19 kDa-interacting protein 3-like protein (BNIP3L)/adenovirus E1B-interacting protein and mitochondrial dysfunction in the hippocampus of mice with sepsis-associated encephalopathy (SAE).Methods:One hundred and eighty C57BL/6J mice, aged 6-8 weeks, weighing 20-25 g, were divided into 4 groups ( n=45 each) using a random number table method: control group (C group), sham operation group (Sham group), SAE group, and SAE+ BNIP3L agonist carfilzomib group (SC group). The sepsis model was developed by cecal ligation and puncture (CLP) in anesthetized animals. In SC group, carfilzomib 2 mg/kg was intraperitoneally injected at 2 h after CLP. Twenty mice in each group were selected, and the survival at 7 days after operation was recorded. Eight surviving mice in each group were selected at 1 week after CLP for Morris water maze test. The remaining mice were sacrificed at 24 h after surgery, and the hippocampal tissues were harvested for determination of the expression of BNIP3L (by immunofluorescence) and BNIP3L in mitochondrial protein (by Western blot) and for microscopic examination of the morphological structure of mitochondria. The mitochondrial ATP content was measured by fluorescein-fluorescence enzyme luminescence method, and the mitochondrial membrane potential (MMP) was measured by fluorescence spectrophotometry. Results:Compared with C and Sham groups, the survival rate was significantly decreased, the escape latency was prolonged, the time of staying at the original platform quadrant was shortened, and the number of crossing the original platform region was decreased, the expression of BNIP3L in the hippocampal mitochondria was down-regulated, the MMP and content of mitochondrial ATP were decreased ( P<0.05), the intensity of fluorescence of BNIP3L in the hippocampus was decreased, and the damage to mitochondrial ultrastructure was marked in SAE group. Compared with SAE group, the survival rate was significantly increased, the escape latency was shortened, the time of staying at the original platform quadrant was prolonged, and the number of crossing the original platform region was increased, the expression of BNIP3L in the hippocampal mitochondria was up-regulated, the MMP and content of mitochondrial ATP were increased ( P<0.05), the intensity of fluorescence of BNIP3L in the hippocampus was decreased, and the damage to mitochondrial ultrastructure was attenuated in SC group. Conclusions:BNIP3L-mediated mitochondrial dysfunction may be involved in the mechanism of SAE developed in mice.
