Abstract:
Innate immunity is the host's first line defense against pathogens invading to the body. Detection of abnormal nucleic acids in the cytoplasm showed that some conserved pathogen associated molecular patterns (PAMPS) triggered type I interferon (IFN) -mediated innate immune responses. The DNA sensor— cGAS (cGAMP Synthase) recognizes and binds to host or pathogen cytoplasmic DNA, promotes the formation of the second messenger cGAMP (cyclic GMP-AMP), and triggers STING (stimulator of interferon genes) dependent downstream signaling. Here we briefly describe the latest progress of the cGAS-cGAMP-STING pathway and its important role in antivirus, and provide new ideas for virus prevention research and new direction for the development of antiviral drugs.

Abstract:
Objective To study the effects of schisandrin B (Sch B) on the apoptosis of human breast cancer MDA-MB-231 cells and its mechanism. Methods Cell counting reagent (CCK-8) was used to detect the effect of Sch B on the survival rate of MDA-MB-231 cells. MDA-MB-231 cells were treated with Sch B (10, 20, 40 μmol/L) for 24 hours. The cell death was detected by Annexin V-FITC/PI. The levels of intracellular reactive oxygen species (ROS) were detected by DCFA-DA fluorescent probe. Apoptosis and the expression of endoplasmic reticulum stress related proteins (Bcl-2、Bax、CHOP、GPR78、PERK、p-PERK、p-eIF2α、eIF2) were detected by Western blot. Results Compared with the blank group, the cell survival rate decreased significantly (P<0.01) with the increase of Sch B concentration, and its IC50 was 19.16 μmol/L. Compared with the control group, Sch B groups (10, 20, 40 μmol/L) inhibited cell clone formation in a dose-dependent manner (P<0.05). Sch B groups (10, 20, 40 μmol/L) induced apoptosis (P<0.05), significantly reduced the expression of anti-apoptotic protein Bcl-2 and significantly increased the expression of pro-apoptotic protein Bax (P<0.05). Sch B groups (10, 20, 40 μmol/L) significantly increased the level of intracellular ROS in a dose-dependent manner (P<0.05). Sch B groups (10, 20, 40 μmol/L) stimulated endoplasmic reticulum stress and increased the expressions of endoplasmic reticulum stress-related proteins CHOP, GPR78 and p-eIF2α in a dose-dependent manner (P<0.05). Conclusion Sch B induces apoptosis of MDA-MB-231 cells through ROS mediated endoplasmic reticulum stress.

Abstract:
Objective To investigate the protective effect of the ethanol extract of Portulaca oleracea L. on acute liver injury induced by carbon tetrachloride in mice, and to analyze its effective components. Methods 80% ethanol purslane extract was centrifuged, vacuum distillated and vacuum dried into whole plant extract, supernatant extract and precipitated extract. Eighty ICR male mice were randomly divided into 8 groups: control group, liver injury model group, whole plant extract low-dose group, high-dose group, supernatant extract low-dose group, high-dose group, precipitation extract low-dose group, and high-dose group. After oral administration of distilled water or three kinds of purslane extract suspensions at different doses for 1 week, olive oil or CCl4 olive oil solution were injected subcutaneously respectively. After 16 hours, serum was collected to detect the levels of ALT, AST and IL-6 to evaluate the protective effect of purslane on acute liver injury. Ultra-high performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-Q-TOF/MS) was used to analyze the effective components of purslane extract. Results Compared with the model group, the levels of serum AST, ALT and IL-6 in high-dose whole plant extract group were significantly reduced. The serum ALT level of mice in the high-dose precipitation extract group was significantly reduced (P<0.05). The serum IL-6 level was decreased, but there was no significant difference. There were no significant changes in the levels of serum AST, ALT and IL-6 in the other intervention groups. 15 main components such as malic acid, citric acid, leucine, isoleucine, adenosine, succinic acid, genistein, tyrosine and phenylalanine were identified by UPLC-Q-TOF/MS. Conclusion Purslane whole plant ethanol extract has hepatoprotective and anti-inflammatory effects on CCl4 acute liver injury mice, which may be a combined effect of 15 active components.

Abstract:
Objective To explore the effects of Humulus lupulus L. extract (HLE) and its mechanism on improving bone formation of Aβ-injured osteoblasts. Methods Osteoblasts isolated from 24 h-old Wistar rats were injured by Aβ1-42 oligomer and intervened with HLE. The proliferation, differentiation and bone mineralization of osteoblasts were determined by MTT assay, alkaline phosphatase (ALP) activity assay and alizarin red staining, respectively. The apoptosis of osteoblasts was detected by flow cytometer. The expression levels of bone formation related proteins, and proteins of Nrf2 and FoxO1 pathways were measured by Western blotting analysis. The intranuclear expression of FoxO1 protein was detected by immunofluorescence. Results HLE significantly improved the cell proliferation, ALP activity and bone mineralization, and inhibited the apoptosis of Aβ-injured osteoblasts. HLE also significantly promoted the expressions of collagen type Ι (COL-I) and osteopontin (OPN) in Aβ-injured osteoblasts. HLE notably activated the Nrf2 and FoxO1 signaling pathways in Aβ-injured osteoblasts by promoting the expressions of related proteins and maintained bone metabolism through relieving oxidative stress. Conclusion This study confirms that HLE can alleviate Aβ-injury to osteoblasts, and preliminarily clarifies the mechanism being related to antioxidation, which provides a new reference for the mechanism research and drugs development for anti-osteoporosis.

Abstract:
Objective To find small molecules binding specifically to signal transducer and activator of transcription3 (STAT3) based on surface plasmon resonance (SPR) technology and confirm their inhibitory activities to STAT3. Methods The biomolecular interaction analysis T200 system based on SPR technology was used to couple the purified protein STAT3 to CM5 chip under the optimal pH conditions. The compounds with high binding response value were screened out from 50 candidate compounds derived from traditional Chinese medicines and the binding specificity was then confirmed. Biological experiments were performed to confirm the inhibitory effects of the screened compounds on STAT3. The binding pattern of STAT3 and the compound was fitted by molecular docking technique. Results More than 10 candidate molecules exhibited binding activities to STAT3 and kinetics assays revealed that only one candidate molecule, apigenin, showed specific binding. Western-blot analysis exhibited that apigenin inhibited the phosphorylation of STAT3 dose-dependently. Luciferase reporter gene assays demonstrated that apigenin also inhibited IL-6-induced STAT3 transcriptional activity in a dose-dependent manner. Molecular docking results showed that apigenin binds to the SH2 domain of STAT3, and interacts with key residues Glu638, Gln644, Gly656 and Lys658 by hydrogen bonds and with Tyr657 through π-π interactions. Conclusion Apigenin was a direct inhibitor of STAT3.

Abstract:
Objective To investigate the effects of ephedrine on the expression levels of brain-derived neurotropic factor (BDNF) and postsynaptic density protein 95 (PSD95) and synapsin1 in PC12 cells, and to explore the mechanism of ephedrine cytotoxicity on PC12. Methods After PC12 cells were treated with different concentration of ephedrine, the cell survival rate was measured by the methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay. The morphology changes of PC12 cells were observed by an inverted microscope. Western blot was used to detect the protein expression levels of BDNF, PSD95 and synapsin1 in PC12 cells. Results Ephedrine decreased the viability of PC12 cell in a concentration-dependent manner,with an IC25 and IC50 of 0.536 mmol and 2.8 mmol, respectively, for PC12 cell death. As ephedrine concentration increased, PC12 cells became smaller in size, with blurred boundary blurred, reduced synapses and shorter axon lengths. The expression levels of BDNF and PSD95 increased significantly. Meanwhile the expression level of synapsin1 decreased. Conclusion The mechanism of ephedrine cytotoxicity on PC12 may be related to the expression levels of BDNF, PSD95 and synapsin1.

Abstract:
Objective To explore the role of clinical pharmacists in rational drug use through the pharmacy care of an elderly pneumonia patient with Chlamydia psittaci infection and drug-induced liver injury. Methods The clinical pharmacists participated in the treatment of one patient with Chlamydia psittaci pneumonia and drug-induced liver injury. Based on the results of second-generation gene sequencing, the characteristics of the pathogen were learned by literature search. The clinical pharmacists monitored the patient’s liver and kidney function, provided a new medication treatment plan to Doctors, and performed patient education during the treatment. Results The initial empirical anti-infective treatment with teicoplanin and imipenem-cilastatin was not effective. After the diagnosis of Chlamydia psittaci and Candida albicans infection, the combination of doxycycline with azithromycin and fluconazole was administered. Drug-induced liver injury was found with this treatment. The clinical pharmacist proposed to switch to doxycycline and clarithromycin with co-administration of magnesium isoglycyrrhizinate and polyene phosphatidylcholine to protect the liver. With this new regime, patient's liver function was improved and the infection was under control. Conclusion Individualized pharmaceutical cares provided by clinical pharmacists helped the safe, rational and effective use of medications.

Abstract:
Objective To investigate the relationship between cystatin C level and the plasma trough concentration of teicoplanin, so as to provide a reference for the rational application of teicoplanin in clinical practice. Methods The clinical data of the patients receiving teicoplanin, who admitted to our hospital from October 2017 to July 2020 were retrospectively analyzed. The distribution of teicoplanin concentration, the difference of teicoplanin concentration under different cystatin C level, and influence factors for teicoplanin concentration (<15 µg/ml) were analyzed. Results A total of 98 patients including 65 males and 33 females, aged 19 to 94 (52.2±16.2) years old, with 141 trough concentrations were enrolled. The trough concentration of teicoplanin was 11.51 (8.35, 19.07) µg/ml, and the range was 3.57-41.93 µg/ml. 95 cases (67.38%) had teicoplanin concentration <15 µg/ml. When the concentration of cystatin C was >1.05 mg/L, the trough concentration of teicoplanin were 11.37 (8.96, 20.52) µg/ml, significantly higher than those when the concentration of cystatin C was in normal [8.68 (6.34, 11.79) µg/ml, Z=−2.636, P<0.05]. Logistic regression analysis showed that cystatin C level was the influencing factor for teicoplanin trough concentration does not meet the standard (OR=1.529, 95%CI=1.001-2.336, P<0.05). Conclusion The concentration of teicoplanin is significantly increased when the cystatin C level is higher than the normal. Cystatin C level is the influence factor for teicoplanin trough concentration not meeting the standard. The cystatin C level may be considered as a reference for teicoplanin dosage adjustment in clinical practice.

Abstract:
Objective To evaluate the cognition, attitude, and barriers of family doctor team members in chongming district of Shanghai to pharmacists joining the team and providing community pharmaceutical care. To provide the reference resources for the establishment of community pharmaceutical care management mode with appropriate suburban characteristics. Methods In a cross-section study conducted in 2020, an online questionnaire was provided to family doctor teams in 18 townships in Chongming District through group WeChat. Descriptive statistical data were used to analyze the cognition, attitude and barrier of family physician team members to community pharmaceutical care. Results Among the 555 participants in the study, 351 (63.24%) were female, 187 general practitioners (33.69%), 226 nurses (40.72%), and 142 public health physicians (25.59%). There were statistically significant differences in CPC cognition among the three classes of family doctor team members (P<0.05). 126 nurses (51.22%) and 84 public health physicians (68.85%) claimed never heard of CPC. 11.48% public health physicians and 23.58% nurses were familiar with the work content and responsibilities of community clinical pharmacists. General practitioners showed relatively high proportion of 34.76%. 34.22% of general practitioners held a "disagree attitude" against that "community pharmaceutical care can improve the medication efficacy for patients". "Insufficient investment in the health sector" and "insufficient community pharmacists" were the main obstacles to the development of community pharmaceutical care. Conclusion The attitude of family doctors in Chongming area to community pharmaceutical care was conservative. Public healthcare persons and nurses had a low awareness to community pharmaceutical care. The development of community pharmaceutical care was limited by the lack of financial investment and manpower.
