Effect of quercetin's anti-breast cancer depending on presence of estrogen receptor via down-regulating long non-coding RNA MALAT-1 and its mechanism / 中国药理学通报

Aim To investigate the molecular mechanism by which quercetin inhibits the malignant behavior of breast cancer cells. Methods Breast cancer cell lines MCF-7 and MB231 were used as the research models. Lentiviral transfection was employed to establish tumor cells with high expression of ERa and MAL-AT-1. The expression of MALAT-1 was assessed using RT-qPCR,and ERa expression was determined through Western blot. Subsequently, CCK-8 assay and colony formation assay were conducted to evaluate cell proliferation. PI staining and adenovirus transfection were performed to observe the inhibitory effects of quercetin on breast cancer cell proliferation. Results 17|3-es-tradiol ( E2 ) promoted the proliferation of MCF-7 breast cancer cells, while 5 jjunol L quercetin reversed the promoting effect of E2 on proliferation ( P 0. 05 ) . Quercetin had no effect on MB231 breast cancer cells. Overexpression of ERa significantly inhibited the pro-proliferative effect of E2 on MB231-ERa cells, and quercetin further suppressed this effect. Additionally , quercetin inhibited the expression of MALAT-1. However,this inhibitory effect was reversed by overexpression of MALAT-1, leading to enhanced cell proliferation , cell cycle progression, and clonal formation a-bility. Conclusions Quercetin exerts its anti-tumor effects on breast cancer cells by regulating MALAT-1, dependent on the presence of estrogen receptor. Quercetin shows potential as a therapeutic drug for breast cancer targeting the estrogen receptor.

Dihydromyricetin Alleviates H9C2 Cell Apoptosis and Autophagy by Regulating CircHIPK3 Expression and PI3K/AKT/mTOR Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the effect and potential mechanism of dihydromyricetin (Dmy) on H9C2 cell proliferation, apoptosis, and autophagy.@*METHODS@#H9C2 cells were randomly divided into 7 groups, namely control, model, EV (empty pCDH-CMV-MCS-EF1-CopGFP-T2A-Puro vector), IV (circHIPK3 interference), Dmy (50 µ mol/L), Dmy+IV, and Dmy+EV groups. Cell proliferation and apoptosis were detected by cell counting kit-8 assay and flow cytometry, respectivley. Western blot was used to evaluate the levels of light chain 3 II/I (LC3II/I), phospho-phosphoinositide 3-kinase (p-PI3K), protein kinase B (p-AKT), and phospho-mammalian target of rapamycin (p-mTOR). The level of circHIPK3 was determined using reverse transcriptase polymerase chain reaction. Electron microscopy was used to observe autophagosomes in H9C2 cells.@*RESULTS@#Compared to H9C2 cells, the expression of circHIPK in H9C2 hypoxia model cells increased significantly (P<0.05). Compared to the control group, the cell apoptosis and autophagosomes increased, cell proliferation rate decreased significantly, and the expression of LC3 II/I significantly increased (all P<0.05). Compared to the model group, the rate of apoptosis and autophagosomes in IV, Dmy, and Dmy+IV group decreased, the cell proliferation rate increased, and the expression of LC3 II/I decreased significantly (all P<0.05). Compared to the control group, the expressions of p-PI3K, p-AKT, and p-mTOR in the model group significantly reduced (P<0.05), whereas after treatment with Dmy and sh-circHIPK3, the above situation was reversed (P<0.05).@*CONCLUSION@#Dmy plays a protective role in H9C2 cells by inhibiting circHIPK expression and cell apoptosis and autophagy, and the mechanism may be related to PI3K/AKT/mTOR pathway.

In order to clarify the pharmacodynamic substances and mechanism of Xiangju Preparations (Xiangju Tablets, Xiangju Drops) in the treatment of rhinitis and sinusitis, the multi-level network integration analysis of "ingredients-targets-pathways" was conducted. 137 chemical constituents were identified in Xiangju Preparations by high pressure liquid chromatography-quadrupole-time of flight mass spectrometry (HPLC-QTOF/MS) for the first time. Network pharmacology analysis was performed on 59 potential active components. The results of network pharmacology analysis demonstrated that the medicinal ingredients in Xiangju Preparations included caffeic acid, senkyunolide F, rosmarinic acid, ligustilide, prim-O-glucosylcimifugin, linarin, magnolin, luteolin, senkyunolide I and gallic acid. These ingredients act on the crucial targets of tumor necrosis factor (TNF), interleukin 1B (IL1B), protein kinase B (AKT1), vascular endothelial growth factor A (VEGFA), signal transducer and activator of transcription 3 (STAT3) and participate in the regulation of advanced glycosylation end products-receptor of AGEs (AGE-RAGE), TNF, nuclear factor kappa B (NF-κB), and cyclic guanosine monophosphate-protein kinase G (cGMP-PKG) signaling pathways to effectively treat rhinitis and sinusitis. The excellent binding performance between above 10 active components and 5 key target proteins was further confirmed by molecular docking, indicating that these 10 ingredients are pharmacodynamic substances of Xiangju preparations. In conclusion, this study preliminarily clarified the effective components and mechanism of Xiangju preparations in the treatment of rhinitis and sinusitis, and provided a theoretical basis for the clinical application of Xiangju preparations.

Food safety risk monitoring ability of institutions for disease control and prevention in a province / 上海预防医学

Objective:To determine the current situation of food safety risk monitoring ability of centers for disease control and prevention （CDCs） in a province， and provide reference for strengthening the construction of food safety monitoring ability in the future. Methods:A self-administered questionnaire survey was conducted among 14 CDCs who are responsible for food safety risk monitoring in the province in 2018. Results:The ratio of food inspection staff with senior， middle， and primary professional titles was 1∶1∶1. The educational background of food inspection staff at the provincial and municipal levels was mainly bachelor degree or above， while that of county level directly under the administration of the province was mainly college degree. The age composition of the staff at the provincial level tended to be elder； however， there were more staff with less working experience at the county level. The qualification proportion of laboratory area was 50%. The distribution proportion of food inspection equipment in the CDC at all levels was 83.3%， 79.5% and 36.3%， respectively. In total， 14 CDCs completed the monitoring task as required. They were all accredited with laboratory qualifications； however， one CDC did not conduct re-evaluation after the certification of food inspection qualification expired. Each CDC ensured the accuracy and reliability of monitoring data through the supervision in food testing. Conclusion:The food safety risk monitoring ability of the CDCs in the province is continuously improved， which can meet the needs of routine monitoring. However， the composition of professional titles of food inspection staff is not very reasonable. There is still a gap between the equipment configuration and the national requirements. The ability of food inspection needs to be improved， in which quality management and laboratory qualification should be further strengthened.

Expression of CaSR in neurons and cardiomyocytes incubated with magnesium-free extracellular fluid and its relationship with the MAPK pathway / 医学研究生学报

Objective At present, studies on the calcium sensing receptor (CaSR) in the pathogenesis of epilepsy are carried out in animal models in vivo and in single cells cultured in vitro. This study was to investigate the expression of CaSR and its relationship with the MAPK pathway in the rat model of epilepsy.Methods The neurons and cardiomyocytes of 3-day-old Wistar rats were cultured for 10 days and randomly divided into groups A (control), B (magnesium-free), C (magnesium free+spermine), D (magnesium free+calhex231), and E (magnesium free+spermine+calhex231). The model of epilepsy was made by abnormal discharge of the neurons induced by coculturing magnesium-free extracellular fluid with cardiomyocytes. The morphological changes of the cells were observed by HE staining and transmission electron microscopy, their survival rate detected by MTT, and the expressions of the CaSR, Bcl-2, P-ERK, P-JNK and P-P38 proteins in the cocultured cells determined by Western blot.Results Compared with the cells in group B, those in group C were swollen and broken with nuclear fragmentation, those in group D showed a relative integrity, and those in group E were also swollen and broken but improved in comparison with those in group C. The survival rates of the cells were (61.08±15.44)%, (82.80±14.37)% and (82.04±17.37)% in groups C, D and E, respectively, all significantly lower than in A (\[100.00±0.00\]%, P<0.01) and B (\[88.88±9.85\]%, P<0.01). The expression of CaSR was markedly higher in group B than in A (\[0.73±0.19\] vs \[0.45±0.12\], P<0.01) but lower than in C (1.32±0.15) and E (1.19±0.12) (P<0.01). The expression levels of Bcl-2 and P-ERK were remarkably lower in group B than in A but higher than in C (P<0.01), and those of P-JNK and P-P38 significantly higher in group B than in A and lower than in C and E (P<0.05).Conclusion Magnesium-free extracellular fluid can damage neurons and cardiomyocytes, increase the expression of CaSR, participate in the MAPK signaling pathway, and mediate the apoptosis of neurons and cardiomyocytes, while CaSR inhibitors can relieve the CaSR agonist-induced damage to the cells.

Evaluation on three short-term animal models of alcoholic liver disease / 药学学报

Alcoholic liver disease (ALD) includes a spectrum of disorders ranging from asymptomatic steatosis, alcoholic steatohepatitis (ASH), fibrosis and cirrhosis. According to epidemical statistics, ALD has been ranked as the second major cause of liver diseases in China. Many animal models have been made in the study of potential therapies. However, in most of the models, the pathological changes are not always consistent with those in patients. There are three widely used short-term animal models of ALD:the acute alcoholic liver injury model, Gao-binge steatohepatitis model and CCl4-alcohol diet induced liver fibrosis model. In this study, we evaluated the pathological responses of these models and compared the responses with the clinical parameters. The liver/body weight ratio was increased and liver histological lesions were induced in alcoholic groups in the three models, while the levels of biochemical parameters and inflammatory factors were affected by different type of treatments. In the acute alcoholic model, the mRNA levels of interleukin-6 (IL-6) and C-C motif chemokine receptor-2 (CCL2) were surprisingly decreased, which was consistent with the transcriptome profile in patients (P P IL-6 and CCL2 (P CCL2 was impacted differently at various stages of ALDs, which can be considered as a potential biomarker.

Clinical characteristics and speech therapy of lingua-apical articulation disorder / 中华儿科杂志

<p><b>OBJECTIVE</b>To explore the clinical characteristics and speech therapy of 62 children with lingua-apical articulation disorder.</p><p><b>METHODS</b>Peabody Picture Vocabulary Test (PPVT), Gesell development scales (Gesell), Wechsler Intelligence Scale for Preschool Children (WPPSI) and speech test were performed for 62 children at the ages of 3 to 8 years with lingua-apical articulation disorder. PPVT was used to measure receptive vocabulary skills. GESELL and WPPSI were utilized to represent cognitive and non-verbal ability. The speech test was adopted to assess the speech development. The children received speech therapy and auxiliary oral-motor functional training once or twice a week. Firstly the target sound was identified according to the speech development milestone, then the method of speech localization was used to clarify the correct articulation placement and manner. It was needed to change food character and administer oral-motor functional training for children with oral motor dysfunction.</p><p><b>RESULTS</b>The 62 cases with the apical articulation disorder were classified into four groups. The combined pattern of the articulation disorder was the most common (40 cases, 64.5%), the next was apico-dental disorder (15 cases, 24.2%). The third was palatal disorder (4 cases, 6.5%) and the last one was the linguo-alveolar disorder (3 cases, 4.8%). The substitution errors of velar were the most common (95.2%), the next was omission errors (30.6%) and the last was absence of aspiration (12.9%). Oral motor dysfunction was found in some children with problems such as disordered joint movement of tongue and head, unstable jaw, weak tongue strength and poor coordination of tongue movement. Some children had feeding problems such as preference of eating soft food, keeping food in mouths, eating slowly, and poor chewing. After 5 to 18 times of therapy, the effective rate of speech therapy reached 82.3%.</p><p><b>CONCLUSION</b>The lingua-apical articulation disorders can be classified into four groups. The combined pattern of the articulation errors is the most common one. Most of the apical sounds are replaced by velar sounds. The speech localization method is very useful in the therapy of apical articulation disorder. For children with feeding problems and oral motor dysfunction, it is needed to improve food texture and administer oral motor skill training.</p>

Clinical analysis of 91 cases with articulation error / 中华儿科杂志

<p><b>OBJECTIVE</b>To study classification of the articulation errors, find the related factors which affect the therapy effect, and compare the therapy effect in the different patterns of the phonemic errors and build up a clinical model of the speech therapy on the basis of more than 4 years speech therapy in the clinic.</p><p><b>METHOD</b>After excluding the organic articulation disorders, 91 cases of consonant phonemic errors were classified into different patterns according to the phonemic placement errors. The 91 cases were divided into two groups as effective one and ineffective one depending on whether the symptoms disappeared or not after the speech therapy. Ten factors including sex, age, oral-motor function problem, developmental delay, history of language development delay, history of middle ear affection, lingua frenata, mental retardation, the therapy frequency and times, were analyzed. The statistics software SPSS (SPSS Inc, 1997) was applied to show the factors related to the therapy effect by logistic multiple stepwise regression analysis. The therapy effect was compared between the single pattern (phonemic error < 2 groups) and multiple pattern (phonemic errors > or = 2 groups).</p><p><b>RESULTS</b>The 91 cases with consonant phonemic errors were classified into four groups. The multiple pattern of the articulation errors was the most common (37 cases, 41%) among the 4 groups, followed by velar errors (33 cases, 36%). The third one was the apico-dental errors (12 cases, 13%) and the last one was the linguo-alveolar errors (8 cases, 9%). Only one case had labiodental error (/f/). The logistic multiple stepwise regression analysis showed that the history of the positive developmental delay, language delay and the frequency of the speech therapy were related to the therapy effect. The effective rate of the speech therapy in the single pattern of the phonemic error was as high as 87% while the one in the multiple pattern group was only 2.7%. The difference was significant (P < 0.000 1) when the therapy effect in these two groups was compared. The clinical model of the speech therapy included speech assessment, designing of the goal, choice of the target sound, sound production and oral-motor functional training.</p><p><b>CONCLUSION</b>The consonant phonemic errors in the clinic represent four groups. The developmental delay, the language delay and frequency of the speech therapy influence the therapy effect. The frequency of the speech therapy should be increased every week, for example not less two times a week. The therapy effect of the single pattern of the phonemic errors is much better than that of the multiple pattern. The primary model of the speech therapy has been built in the clinics.</p>
