Objective To investigate the efficacy of losartan on the improvement of heart function and its effect on uric acid in patients with chronic heart failure (CHF). Methods Eighty-five patients with CHF were divided into two groups randomly. Routine anti-CHF treatment included cardiotonic, diuresis, isosorbide dinitrate, beta-blockers. In losartan group(n=43), patients were given routine anti-CHF treatment and losartan. The patients in control group(n=42) were treated by routine anti-CHF treatment and Benazapril. The heart functional was evaluated. The content of serum uric acid, electrocardiogram, and Duppler ultransonography were measured before and after treatment respectively. Results The variance of heart function, left ventricle diastoic diameter (LVDD), left ventricle ejection fraction (LVEF) and cardiothotic ratio did not show statistical difference. However, they were improved sharply as compared with base-line condition in both groups after 3 months and 12 months treatment(P

This study is aimed to evaluate the clinical application of the millimeter wave and magnetism light compound therapy. The EHF-98B MMW. RL compound therapy apparatus made in the University of Electronic Technology(Chengdu) was used in 171 patients. The superficial, skin lesions or the visceral reflected skin regions (acupoints) were directly exposed to the light from the apparatus. All the cases were divided into five groups, namely skin mucosa superficial lesions, trauma of the bone and joint soft tissue, surgical incision, ENT infections, and rare intricate diseases. The therapeutic effects observed in the groups were analyzed and evaluated by means of 4 levels. As for the 171 patients, the cure rate was 42.7% (73 patients), the effective rate 25.1%(43 patients), the improvement rate 31%(53 patients), and no effect constituted 1.2%(2 patients). The total effective rate was 98.8%. This therapy was especially effective for treating chronic cervicitis, cervical erosion, soft tissue trauma, surgical incision. Also it was effective for treating some rare intricate diseases, e.g. sterility, vitiligo, Behcet disease. So the millimeter wave and magnetism light compound therapy may find wide clinical applications.

Objective To investigate the clinical efficacy of extracorporeal shock wave therapy combined with traditional Chinese medicine iontophoresis in elderly patients with knee osteoarthritis (KOA). Methods Fifty-six patients with KOA were randomized into the drug therapy group(n=28) receiving only traditional Chinese medicine iontophoresis therapy for four weeks and the combined treatment group(n= 28)receiving extracorporeal shock wave therapy combined with traditional Chinese medicine iontophoresis therapy for four weeks.WOMAC score as an specific severity-of-illness score was used to evaluate knee joint function of patients before and four-week after treatment. Results WOMAC scores of all patients were significantly decreased which indicated states of an illness were improved after four-week treatment as compared with pre-treatment(all P< 0.05).The combined treatment group versus the drug therapy group showed markedly lower WOMAC scores,including pain score(3.17 ± 1.03 vs.5.27 ± 1.58,t= 7.316,P< 0.05),morning stiffness score(2.23 ± 0.91 vs.3.32 ± 1.14,t= 3.440,P< 0.05),activity restrict of daily living score(20.13 ± 6.46 vs.27.35 ± 13.28,t= 4.691,P< 0.05)and total score(28.37 ± 11.62 vs.40.16 ± 5.93,t=8.015,P<0.05). Conclusions Compared with single traditional Chinese medicine iontophoresis, the extracorporeal shock wave therapy combined with traditional Chinese medicine iontophoresis therapy may significantly reduce the pain and morning stiffness degree,and enhance activities of daily living in elderly patients with KOA.

Objective:To explore the application of case-based learning (CBL) guided by the International Classification of Functioning, Disability and Health (ICF) in teaching internship of rehabilitation medicine undergraduates.Methods:According to the implementation time of ICF-guided CBL teaching (February 2023), 55 students who interned before February 2023 were included in the control group and received routine teaching, and 54 students who interned after February 2023 were enrolled in the observation group and received ICF-guided CBL teaching. The assessment score, professional identity score, learning adaptability score, communication ability score, and critical thinking score were evaluated before and after teaching. SPSS 23.0 was used for t-test and chi-square test. Results:After teaching, the assessment score, professional identity score, learning adaptability score, communication ability score, and critical thinking score of both groups of students significantly increased. Compared with the control group, the observation group showed significantly higher assessment score [(166.01±14.21) vs. (150.19±13.73)], professional identity score [(124.50±12.73) vs. (103.94±10.42)], learning adaptability score [(71.93±7.43) vs. (57.69±6.71)], communication ability score [(23.77±4.21) vs. (19.97±3.94)], and critical thinking score [(150.03±11.20) vs. (129.38±10.57)].Conclusions:ICF-guided CBL teaching can help to improve the professional identity and learning adaptability of rehabilitation medicine undergraduates, enhance their skill of communication with patients and critical thinking ability, and increase their professional theoretical knowledge and practical ability. Therefore, ICF-guided CBL is a beneficial exploration of teaching internship of rehabilitation medicine undergraduates.

Objective:To investigate impacts of usnic acid(UA)on malignant behavior of gastric cancer cells by regulating the chemokine(C-C motif)ligand 2(CCL2)-CCL2 receptor(CCR2)signal axis.Methods:SGC-7901 cells,a well growing human gastric cancer cell line,were treated with different concentrations of UA,which were grouped into low concentration(UA-L)group(62.5 μmol/L UA),medium concentration(UA-M)group(125 μmol/L UA)and high concentration(UA-H)group(250 μmol/L UA);meantime,the cells were transfected with CCL2 overexpression vector(pc DNA3.1 CCL2),empty vector(pc DNA3.1),silenced CCL2(si CCL2)and negative control(si control),and SGC-7901 cells were treated with 250 μmol/L UA,labeled as UA-H+pc DNA3.1 CCL2 group,UA-H+pc DNA3.1 group,UA-H+si control group and UA-H+si CCL2 group,another untreated SGC-7901 cells were taken as the control group.Flow cytometry,MTT and qRT-PCR were applied to detect cell apoptosis,proliferation,and expres-sion levels of CCL2 and CCR2 mRNA;Western blot was applied to detect expression levels of PD-L1,apoptotic protein(Bax),proli-ferative protein(CyclinD1,CCL2,CCR2)and immune escape related protein(B7H1);after co-culturing with CD8+T cells isolated and cultured in vitro,ELISA was applied to detect levels of IL-4,IFN-γ and IL-10 in the supernatant.Gastric cancer cells in each group were co-cultured with activated peripheral blood mononuclear cell(PBMC)1∶1 for 72 hours,and the sensitivity of gastric can-cer cells in each group to T-cell-mediated killing was compared.Results:Compared with control group,cell proliferation rate,IL-10 level,CyclinD1,PD-L1,CCL2,CCR2 and B7H1 protein and mRNA expressions,cell counts after co-culturing with activated PBMC 1∶1 for 72 hours in UA-L group,UA-M group and UA-H group were obviously reduced,while apoptosis rate,IL-4 and IFN-γ levels,Bax protein expression were obviously increased(P<0.05);compared with UA-H+pc DNA3.1 group,cell proliferation rate,IL-10 level,CyclinD1,PD-L1,CCL2,CCR2 protein and mRNA expressions,cell counts after co-culturing with activated PBMC 1∶1 for 72 hours in UA-H+pc DNA3.1 CCL2 group were obviously increased,while apoptosis rate,IL-4 and IFN-γ levels,and Bax protein ex-pression were obviously reduced(P<0.05);compared with UA-H+si control group,cell proliferation rate,IL-10 level,CyclinD1,PD-L1,CCL2,CCR2 and B7H1 protein and mRNA expressions,cell counts after co-culturing with activated PBMC 1∶1 for 72 hours in UA-H+si CCL2 group were obviously reduced,while apoptosis rate,IL-4 and IFN-γ levels and Bax protein expression were obviously increased(P<0.05).Conclusion:UA can inhibit gastric cancer cells proliferation,immune escape,and induce apoptosis,which may be related to the inhibition of the CCL2-CCR2 signaling axis.

OBJECTIVE To provide reference for improving the rational use of antimicrobial drugs in primary township medical institutions. METHODS Based on the county prescription pre-review center， a team led by anti-infective clinical pharmacists constructed the management mode for the use of antimicrobial drugs in county-level medical communities with clinical pharmacists as the main team by finding out the main problems in the use of antimicrobial drugs in primary township medical institutions， providing feedback on the problems， organizing relevant training for the problems， improving the customization rules of the prescription pre-review software， implementing the automatic interception and pharmacist online prescription review and other measures. Data on the use of antimicrobial drugs were collected and compared in the 15 primary township medical institutions between January-June in 2022 （before the implementation of the mode） and January-June in 2023 （after the implementation of the mode）. RESULTS Compared with before the implementation of the mode， the utilization rate of antimicrobial drugs in outpatients of primary township medical institutions decreased from 24.97% before the implementation of the mode to 19.39% after the implementation of the mode； the utilization rate of antimicrobial injection in outpatients decreased from 66.10% to 46.80%； the utilization rate of intravenous drip of antimicrobial drugs in outpatients decreased from 52.33% to 40.35%； the rates of combined use of antimicrobial drugs in outpatients decreased from 12.70% to 8.19%； the reasonable rate of antimicrobial prescribing in outpatients increased from 55.28% to 73.93%. After the implementation of the mode， the proportion of antimicrobial prescriptions for each diagnosis was basically the same as before； the defined daily dose system （DDDs） and proportion of a few antimicrobial drugs changed compared with before according to the anatomical therapeutic chemical classification of drugs， among which DDDs of lincomycin， gentamicin and other drugs declined significantly； DDDs of antimicrobial drugs for each classification was basically the same as before according to AWaRe classification. CONCLUSIONS The management mode of the use of antimicrobial drugs led by anti-infective clinical pharmacists is constructed in the prescription pre-reviewing center of county-level medical communities， which can effectively improve the rational use of antimicrobial drugs in the primary township medical institutions.
