Basic skills for use of library is the initial course of information literacy teaching system in our universi-ty. Two years have been past since its teaching reform from 2014, namely classroom teaching in combination with project practice. The connotation and model of project teaching method were thus described in this paper with stress laid on its implementation and adjustment. Project teaching method achieved excellent results in the past two years, which were highly appraised by the teaching administration departments, teachers and students whose information literacy was effectively improved.

Objective:To study the influence of rutin in the morphology of renal tissue of the diabetic mice induced by streptozotocin(STZ), and to clarify the effect of rutin on the kidney tissue damage.Methods:Twelve mice of the total 70 Kunming mice were used as normal group, the other were used to estabish type 1 diabetes mouse models by intraperitoneally injected with STZ (62.5 mg·kg-1), once daily for 5 d.The successfully established model mice were randomly divided into model group,low dose (50 mg·kg-1)of rutin group, high dose (100 mg·kg-1) of rutin group and irbesartan group (45 mg·kg-1).The mice in model group and normal group were given the carboxy methyl cellulose(CMC) and the other mice were given drugs by intragastric administration once daily for 8 weeks accordingly.The weight and blood glucose of the each mouse were determined.Full automatic biochemical analyzer was used to detect the levels of serum creatinine (Cre) and blood urine nitrogen (BUN) of the mice , and the kidney index was calculated.The morphology of renal tissue was observed by HE staining, Masson staining and electron microscope.Results:After injection of STZ,the model success rate was up to 98%.Compared with normal group, there was no significant difference in the weight of the mice in other groups before administration(P>0.05).After administration of rutin, the weights of the mice in model group, low dose of rutin group, high dose of rutin group and irbesartan group were significantly decreased (P<0.05).Compared with model group, the levels of blood glucose of the mice in low and high doses of rutin groups were significantly decreased(P<0.05);the levels of Cre and BUN were significantly reduced (P<0.05);the kidney index of the mice in high dose of rutin group was significantly decreased (P<0.05).Compared with normal group,the kidney tissue of the mice in model group was seriously damaged;glomerular was weaked, the kidney tissue fibrosis was serious, glomerular basement membrane was diffusely thickened and foot process was coalesced or overgrow.Compared with model group,the degree of injury of the mice in low and high doses of rutin groups were significantly improved, especially in high dose of rutin group.Conclusion:Rutin can improve the renal function of diabetic mice induced by STZ and reduce the degree of renal tissue damage in the diabetic mice

The Libguides subject service platform that integrates technologies, resources and service has effectively promoted the subject service in library.Its introduction, construction and achievements in Medical Library of Chinese PLA were described with strategies proposed for improving its problems.

Objective To clone the cDNA encoding human HMGB1, express it in E. coli, and identify its biological activity. Methods Human HMGB1 cDNA was amplified by RT-PCR and cloned into vector pUC19. After sequence analysis, the cDNA was ligated into prokaryotic expression vector pQE-80L and induced by IPTG to express HMGB1. The protein was purified with Ni~(2+)-NTA chromatography and polymyxin B affinity column. To identify the function of purified protein, the product was co-cultured with THP1 cells. Results Recombinant expression plasmid pQE-80L/HMGB1 was constructed successfully. After purification, the protein purity reached 96%. The recombinant HMGB1 stimulated THP1 to secrete TNF-? . Conclusion The highly purified HMGB1 was obtained successfully, which showed biological activity. These results lay the foundation for further research on the function of human HMGB1.

Objective To explore the potential mechanism underlying the treatment of pediatric asthma using Xiaoer Zhixiao Pingchuan Granules through network pharmacology analysis and animal experimental validation.Methods Active components and their associated targets in Xiaoer Zhixiao Pingchuan Granules were identified through screening and retrieval of TCMSP,BATMAN-TCM,and UniProt databases.Disease-related targets for pediatric asthma were selected from GeneCards,DisGeNET,and OMIM databases.The target protein-protein interaction(PPI)relationship between the intersecting targets of the two was obtained through the STRING database,and import it into Cytoscape 3.8.0 software to construct a PPI network.GO and KEGG enrichment analyses were conducted using the Metascape platform to identify potential pathways.An asthmatic mouse model was induced by ovalbumin,and different concentrations of Xiaoer Zhixiao Pingchuan Granules were administered as interventions.Histopathological changes were evaluated using HE staining and PAS staining,and the network pharmacology findings were validated through Western blot analysis.Results A total of 154 active ingredients targeting 283 pediatric asthma-related genes were identified in Xiaoer Zhixiao Pingchuan Granules.KEGG enrichment analyses revealed significant enrichment of signaling pathways such as the PI3K-Akt signaling pathway,TNF signaling pathway,and MAPK signaling pathway among intersection targets.Thirteen key targets were identified through topological analysis of ingredients-targets-pathways network.Animal experiments demonstrated that Xiaoer Zhixiao Pingchuan Granules significantly alleviated ovalbumin-induced airway inflammation and goblet cell hyperplasia,while downregulating the expression of key proteins in the PI3K-Akt signaling pathway(P<0.05).Conclusion The therapeutic efficacy of Xiaoer Zhixiao Pingchuan Granules in pediatric asthma involves a multi-pathway and multi-target mechanism,with the PI3K-Akt signaling pathway emerging as a potential key molecular target.

OBJECTIVE:To provide references for clinicians in the choice of antihypertensive drugs.METHODS:The antihypertensive efficacy 6 classes(or 15 kinds) of antihypertensive drugs in a monotherapy in the treatment of 370 patients with essential hypertension(EH) were compared.RESULTS:The blood pressure was effectively lowered by all of the antihypertensive drugs except doxazosin,and doxazosin and torasemide showed inferior efficacy in the reduction of diastolic blood pressure(DBP).CONCLUSION:Calcium antagonists with prolonged action,angiotensin converting enzyme inhibitor(ACEI),angiotens-in receptor antagonist,and the monotherapy of Terazosin or Indapamide can all effectively bring down the blood pressure.It is suggested that low-dose doxazosin and torasemide should not be used alone in treating essential hypertension.

Objective To better mobilize the work motivation of the majority of medical staff and to explore the optimization strategy of the remuneration distribution mechanism in public hospitals.Methods A semi-structured interview was conducted on employees of a large public hospital in Henan Province using purposive sampling method in March 2024.Sort out,code,and integrate interview data based on grounded theory.Results Based on 40 interview materials,44 initial concepts,14 basic categories,6 main categories,and 3 core categories were summarized.A model of pay distribution mechanism in public hospitals based on pay distribution principle,pay distribution structure and pay management system was constructed.Conclusion It is recommended that hospitals ensure the fairness and competitiveness of salary distribution,implement diversified salary policies,and continuously improve the salary distribution structure and supervision and management system.
