Qi stagnation and qi deficiency are associated with depression in college students.

Objective: The current study aims to investigate the correlations between qi stagnation, qi deficiency, and depression levels among college students. Method: This study investigated 403 college students and measured their levels of depression, qi stagnation, and qi deficiency to analyze the relationship between these three variables. Pearson correlation and linear regression statistical techniques were utilized. Results: (1) On average, college students reported mild depressive symptoms; (2) college students manifested low levels of qi stagnation and qi deficiency. (3) There exists a strong positive correlation between qi stagnation and qi deficiency; (4) a moderate positive correlation is present between depression and both qi stagnation and qi deficiency among college students. All these results support the mechanism by which qi stagnation and qi deficiency contribute to depression in traditional Chinese medicine theory. Conclusion: Qi stagnation and qi deficiency are moderately associated with depression levels in college students. It is feasible to use traditional Chinese physical therapy for qi regulation to alleviate depressive symptoms among college students.

Distribution and change of the pathogens and multi-drug resistant organisms in intensive care unit during 6 years / 国际检验医学杂志

Objective To investigate the distribution and changes of pathogens in intensive care unit of our hospital from 2010 to 2015,and provide treatment suggestions for infection.Methods The data of pathogens and multi-drug resistant organisms(MDROs)in ICU from 2010 to 2015 were analyzed retrospectively by WHONET5.6,Microsoft Office Excel2007 and SPSS19.0.Results The numbers of pathogens in ICU were increasing year by year while the top six were Acinetobacter baumanni,Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli,Staphylococcus aureus and Candida albicans.The dominant MDROs were multi-drug resistant Acinetobacter baumanni,multi-drug resistant Pseudomonas aeruginosa,extended spectrum β lactamase producing Escherichia coli and Klebsiella pneumonia,methicillin-resistant coagulase negative Staph-ylococcus and methicillin-resistant Staphylococcus aureus,etc.There were statistically dramatic significant differences of most MDROs during the six years(P<0.01).Conclusion The pathogens of ICU were mainly bacteria related to the healthcare associated infection,and the multi-drug resistance was obviously in dynamic change as well as most pathogens.As a suggestion,antibiotic agents should be used rationally according to the antimicrobial susceptibility results for treating the MDROs.

Analysis of metallo-beta-lactamase producing of strains resistant to imipipenem in pseudomonas aeruginosa / 国际检验医学杂志

Objective To detect the situation of metallo-beta-lactamase(MBL) producing of strains resistant to imipenem in pseudomonas aeruginosa(PA) isolated from hospital patients from April to July in 2005.Methods PA strains were isolated and antimicrobial resistances were done by the VITEK auto-microbic system.MBL producing strains were detected by Kirby-bauer method.Results 103 strains of PA were isolated. There were 47 strains resistant to imipenem and 16 strains resistant to ceftazidime. 8 strains were found MBL producing. Accounted for 17.0% of resistance strains to imipenem. One of 8 strains was sensitive to levofloxacin,others were resistant to such antibiotics as carbenicillin, amikacin, ticarcillin/clavulanic acid, cefoperazone, ceftazidime, cefepime, netilmicin, trimethoprim/sulfamethoxazole, piperacillin/tazobactam, ciprofloxacin. Non-MBL producing strains were found resistant to almost all antibiotics, except that 2 strains were sensitive to carbenicillin and one was sensitive to amikacin.Conclusion Among the PA strains isolated from clinic, both MBL producing strains and non-MBL ones were multiple antimicrobial resistance.It was one of the antimicrobial merchanisms that MBL producing led to PA resistant to cephalosporins and carbapenems. Antimicrobial agents should be chosen reasonably under the help of laboratory detecting this type correctly so as to reduce the antimicrobial resistance.
