The original teaching of clinical pharmacy for stomatology course did not let students aware of the importance of drugs in the treatment of oral diseases. The original teaching framework was rearranged:decentralizing knowledge of oral diseased related clinical pharmacy into several mod-ules;setting general knowledge into the oral basic medical module;adding the practice of visiting the pharmacy and manufacturing laboratory. Teaching process was closely combined with clinics and was integrated with disease-centered oral medicine curriculum integration system. Students responded that the teaching effect was better. The rearranged teaching method can enhance students' attention on drug treatment for oral diseases,improve their ability of clinical medication and promote the teaching quality.

Objective:To explore the protective cognition of the first batch of nurses against novel coronavirus pneumonia on apparatus-related stress injury, so as to provide reference for formulating and implementing relevant training and improving management measures.Methods:Using the phenomenological method of qualitative research, from January 20, 2020 to February 17, 2020, a half structured in-depth interview was conducted among the echelon nurses who completed the first batch of nurses against novel coronavirus pneumonia on apparatus-related stress injury. A total of 13 nurses in isolation wards were interviewed for the study.Results:Using the method of Colaizzi phenomenology to analyze the interview data, the related knowledge cognition was low, the identification of risk factors was limited, the risk assessment was not carried out, the treatment measures were not timely, the awareness of protection was lacking, the management training was not perfect, and the medical protection materials were not enough.Conclusion:The first batch of nurses to fight against novel coronavirus pneumonia had a low awareness of the prevention of medical device-related stress injury. Hospital managers should strengthen the training of related knowledge, improve management strategies, enhance the awareness of protection, and identify risk factors early, take preventive measures to ensure the safety and health of front-line medical staff in a timely manner.

Objective To observe the analgesia effects of ropivacaine with sufentanil or dezocine on continuous femoral nerve block (FNB)after total knee arthroplasty (TKA).Methods Sixty un-dergoing selective unilateral TKA patients,received postoperative analgesia with continuous FNB for 48 hours,were randomly divided into three groups according to the drug formulations:0.225% ropiv-acaine (group R),0.1 5% ropivacaine mixed dezocine 10 mg (group D),and 0.1 5% ropivacaine mixed sufentanil 1 μg/kg (group S);the visual analogue scale (VAS)in resting state (RVAS), active functional exercise state (AVAS),passive functional exercise state (PVAS)were recorded at 1,3,7 d after surgery.The other analgesics dosage and the incidence of nausea and vomiting and other complications were recorded.Results Compared with preoperative state,the RVAS scores in three groups were significantly lower at 1,3,7 d after surgery,the PVAS scores were significantly lower at 7 d after surgery (P <0.05).Compared with group R,the RVAS scores were significantly higher ei-ther in groups S or D at the 3 d postoperatively (P <0.05).There were no significantly difference in adverse reaction among three groups.Conclusion Ropivacaine combined with sufentanil or dezocine through continuous FNB can provide a effectual postoperative analgesia in TKA patients without an increase in adverse events.But compared to 0.225% ropivacaine,0.1 5% ropivacaine with sufentanil or dezocine may not keep a longer analgesia duration,this is more obvious observed in dezocine group.

Objective:To explore the effects of low birth weight on temperament and behavior prob-lems of children aged 2~3 years. Methods:50 low birth weight (LBW) children and 380 normal birth weight (NBW) children were investigated and assessed by Achenbach's children behavior checklist and tod-dler temperament questionnaire. Results:①Temperament: Independent t-tests identified that NBW children were significantly more active than LBW children(t=2.192, p=0.029). No significantly difference of tempera-ment distributing was found between LBW children and NBW children (p=0.943). ②Behavior problems: In-dependent t-tests identified that NBW children had more sleep problems than 1LBW children(t=2.20,P=0.031). There was more behavior problems of social withdraw in LBW children than NBW children (? 2 =5.427,p=0.02). Conclusion:LBW Children were less active than NBW children and they had high incidences in behavior problems of social withdraw.

Objective To observe the expression of anti-cardiac myosin antibody(AMA) and the collagen volume fraction(CVF) in serum in mice with chronic viral myocarditis(CVMC),and to explore the preventive and protective function of oxymatrine on myocardium.Methods BALB/c mice(n=60) were infected with coxsackievirus B3(CVB3) of increased dose biweekly to establish CVMC model.Mice in normal control group(n=8) received equal-volume 9 g?L-1 saline without CVB3 at the same time.The surviving mice in CVMC model group were randomly divided into CVMC control group(n=8) and oxymatrine therapy group(n=8) at the 42th day.From then on,mice in oxymatrine therapy group were treated with oxymatrine at the dose of 100 mg?kg-1?d-1 by gastric perfusion once a day for 28 days,and meanwhile mice in CVMC control group and the normal control group received equal-volume 9 g?L-1 saline by gastric perfusion every day.Then all mice were sacrificed at the end of the experiment.The ratio between heart weight to body weight(HW/BW) was calculated.Myocardium slides were stained with collagen specific Picric acid-Sirius red staining,and the CVF was calculated with image analysis software.The serum level of AMA(optical density value,A value) was detected by enzyme-linked immunosorbent assay(ELISA).Results HW/BW(0.007 9?0.000 3),CVF [(15.30?1.08)%] and the A value of AMA(0.286?0.053) in mice of CVMC control group were increased significantly compared with those in normal control group HW/BW(0.005 5?0.000 2),CVF[(6.84?1.11)%],the A value of AMA(0.160?0.050)(Pa

ATP-binding cassette transporter A1 (ABCA1) and scavenger receptor class B type I (SR-BI/CLA-1) are the key proteins in reverse cholesterol transport (RCT). The high expression of ABCA1 and SR-BI/CLA-1 can decrease the danger of atherosclerosis. The purpose of the study is to find ABCA1 and CLA-1up-regulators for treating atherosclerosis by using cell-based high throughput screening models. Among 20 000 compounds screened, E0869 [1-(3, 4-dimethylphenyl)-1-oxopropan-2-yll4-((methylsulfonyl)methyl)benzoate] was found as the positive hit. The up-regulated activities of E0869 in ABCAl1-LUC and bCA-l1-LUC HepG2 cell were 160% and 175%, respectively. The EC50 values of E0869 in ABCAl1-LUC and CLA-l1-LUC HepG2 cell were 3.79 and 1.42 pμol- x ,(-1) respectively. E0869 could upregulate the mRNA and protein levels of ABCA1, SR-BI/CLA-1 and ABCGJ1genes in HepG2 and RAW264.7 cells by Real-Time Quantitative PCR and Western blotting analysis, but could not influence the expression of FAS, SREBP-l1 and CD36. Foam cell assay showed that E0869 could inhibit lipids accumulation in mouse peritoneal macrophages RAW264.7. Cholesterol efflux assay showed that E0869 could induce HDL-mediated cholesterol efflux in mouse peritoneal macrophages RAW264.7. In conclusion, E0869 could up-regulate ABCA1 and CLA-1 activity, and had good anti-atherosclerotic activity in vitro.

In the previous study, a high-throughput screening method was established to find the antagonists of CD36. In the present study, a new compound named IMB-1680 was found using this method. The anti-atherosclerotic activities of IMB-1680 were then evaluated. Dose-dependent activities of IMB-1680 were detected by using Sf9 [hCD36] and CHO [hCD36] models. Fluorescence microscopic photography and flow cytometry were used to analyze uptake of mLDL. Foam cell test with RAW264.7 macrophages was used to examine lipid accumulation. The results showed that IMB-1680 inhibited CD36 activity with IC50 of 2.80 and 8.79 micromol x L(-1) in Sf9[hCD36] and CHO [hCD36] cells, respectively. Fluorescence microscopic photography and flow cytometry revealed that IMB-1680 could significantly reduce DiI-AcLDL uptake. Meanwhile, IMB-1680 also could reduce lipids accumulation in RAW264.7 macrophages. In all, the data indicated that IMB-1680 might be a potent effective anti-atherosclerotic leading compound.
