ABSTRACT
Objective@#The aim of the study was to investigate the association of outdoor physical activity and insomnia symptoms with depressive symptoms in college students, so as to provide a theoretical basis for preventing and improving depression of the college students.@*Methods@#A sample survey of 9 349 college students from 4 colleges and universities in 3 provinces in Hubei, Jiangxi and Chongqing were conducted from November to December 2021. The Patient Health Questionnaire, Insomnia Severity Index and outdoor physical activity questionnaire were used to evaluate the depressive symptoms, insomnia symptoms and outdoor activities of college students, respectively. The χ 2 test was used to compare the difference of the positive rate of depressive symptoms in college students. Logistic regression analysis was used to analyze the association between outdoor physical activity, insomnia symptoms and depressive symptoms. Generalized linear model was used to analyze the association of interaction effect of outdoor activity and insomnia symptoms with depressive symptoms.@*Results@#The detection rate of depressive symptoms in college students was 37.4%. Significant differences in the detection rate of depressive symptoms were observed among college students with different majors, nationalities,educational backgrounds, family residence, family type, family economic conditions, study burden, number of friends, father s education level,mother s education level( P <0.05). Logistic regression analysis showed that outdoor physical activity ( OR=0.51-0.69, P <0.01) and insomnia symptoms ( OR=6.15-21.30, P <0.01) were associated with depressive symptoms( P <0.01). Generalized linear model showed that insomnia symptoms( B =0.57), outdoor physical activity ( B =-0.15) and their interaction terms ( B =-0.02) were associated with college students depression( P <0.05).@*Conclusion@#This study suggests that insufficient time for outdoor physical activity and insomnia symptoms may increase the risk of depressive symptoms in college students. College students with insufficient time for outdoor physical activity and insomnia have a higher risk of developing depressive symptoms.
ABSTRACT
Many efforts have been made to understand excitotoxicity and develop neuroprotectants for the therapy of ischemic stroke. The narrow treatment time window is still to be solved. Given that the ischemic core expanded over days, treatment with an extended time window is anticipated. Bestrophin 1 (BEST1) belongs to a bestrophin family of calcium-activated chloride channels. We revealed an increase in neuronal BEST1 expression and function within the peri-infarct from 8 to 48 h after ischemic stroke in mice. Interfering the protein expression or inhibiting the channel function of BEST1 by genetic manipulation displayed neuroprotective effects and improved motor functional deficits. Using electrophysiological recordings, we demonstrated that extrasynaptic glutamate release through BEST1 channel resulted in delayed excitotoxicity. Finally, we confirmed the therapeutic efficacy of pharmacological inhibition of BEST1 during 6-72 h post-ischemia in rodents. This delayed treatment prevented the expansion of infarct volume and the exacerbation of neurological functions. Our study identifies the glutamate-releasing BEST1 channel as a potential therapeutic target against ischemic stroke with a wide time window.
ABSTRACT
ABSTRACT OBJECTIVE：To establish the infusion sequence regulation procedure of PIVAS，and implement individual regulation. METHODS：By combining factors such as liquid volume of each batch，incompatibility between groups and specific solvents of specific drugs，intelligent prompt system and the artificial intelligent regulation system of infusion sequence were successively established to sequence the therapeutic drugs and adjuvant drugs used for the patients with different diagnoses and different purposes in different inpatient areas in a day，so as to realize intelligent control of individual infusion sequence. From Jan. to Sept. in 2017 and from Jan. to Sept. in 2019 as research stages before and after the intelligent control of individualized infusion sequence，the control effect was evaluated with the proportion of reasonable number of infusion priority cases，the proportion of appropriate number of elderly patients’batch liquid volume cases，the proportion of incompatibility cases between separate groups， the number and cost of flushing tubes as index. RESULTS：After regulating infusion sequence individually，the proportion of reasonable infusion priority rose from 5.56％ to 98.72％ ；the proportion of batch liquid quantity appropriate cases in elderly patients rose from 9.58％ to 98.10％；the proportion which separated the incompatibility between groups rose from 41.03％ to 99.12％；the number of washing tube dropped to（0.95±0.43）times/ward/d from（12.95±0.57）times/ward/d；the cost of washing tube could be saved 85 800 yuan/year. CONCLUSIONS：The implementation of individualized infusion sequence regulation promote safe and effective infusion，and provide reference for pharmacists of PIVAS in China to carry out precise pharmaceutical care.
ABSTRACT
OBJECTIVE：To evaluate th e eff ects of infusion sequence regulation on the promotion of intravenous rational drug use. METHODS ：The intelligent control of infusion sequence was realized with Markov chain machine learning method on the basis of intelligent reminder manual labeling infusion sequence. Selected from Binhu Hospital of Hefei during Jan. to Sept. 2017， 164 800 inpatients’medication orders were collected as data before intelligent control of infusion sequence ，and 264 600 inpatients’ medication orders were collected as data after intelligent control of infusion sequence. The correct rate of incompatibility ，storage time limit ，administration frequency ，chronopharmacology，preventive drugs ，drug interaction ，auxiliary drugs and infusion sequence for intravenous irritant drugs were compared before and after regulation ；the times of flushing tube ，the cost of flushing tube infusion and the change of liquid property in the infusion tube were compared before and after regulation. RESULTS ：The correct rate of incompatibility ，storage time limit ，administration frequency ，chronopharmacology，drug interaction and infusion sequence for auxiliary drugs after regulation were significantly higher than before regulation ；the correct rate of infusion sequence for preventive drugs and intravenous irritant drugs ，the times of flushing tube ，the cost of flushing tube infusion and the case number of the liquid change （proportion） in infusion tube were significantly lower than before regulation （P＜0.001）. CONCLUSIONS：Intelligent regulation of infusion sequence can improve the rationality of intravenous medication sequence to a certain extend.
ABSTRACT
Eight sub-databases of pharmacological information on rational use of medicines were designed and established. These sub-databases cover dosing frequency, therapeutic drug priority to auxiliary medication, infusion shelf-life after admixture, incompatibility of two continuous infusion in the vein infusion tube, chronopharmacology, drug interaction involved in administration sequence , venous irritative drugs and preventive medicine. Once the standing order delivery to PIVAS involves any of these sub-databases, the system will prompt in turn " Auxiliary" , " Time limit" , " Taboo" , " Chronopharmacology" , " Interaction" , " Irritative" and " Preventive (therapeutic)" , starting from therapeutic drug priority to auxiliary medication. Pharmacists would make a reasonable sequence of the corresponding infusion and label the administration sequence on the infusion tag according to the prompt.Compared to the circumstance prior to this system, the wards with the infusion sequence labeling and equipped with intelligent prompt increased from 2 to 43; the percentage of such inpatients increased from 0.50% to 66.33%; the percentage of medical orders increased from 0.72% to 78.94%. The time spent by pharmacists for the same workload reduced from 73.44 h per day to 1.94 h per day. The times of flushing infusion tube reduced from 34.42 to 1.49 per ward and per day. The cost of flushing infusion tubes reduced by a big margin. PIVAS has established a method of regulating infusion administration sequence by an intelligent prompt system, based on improved safety and effectiveness of medication.
ABSTRACT
For the issues existed in training of general practitioners, with characteristics of community health-care service centers (CHS) and large-scale urban hospitals, a training model of exchange physicians between hospitals and CHSs was formulated. After three-month practice, a general practitioner-specialist technical cooperation group was established. The new model not only promoted construction of a two-way referral system, but also created environmental condition for training community physicians.
ABSTRACT
Aim To establish method and main evaluation indexes of collagen induced arthritis ( CIA) model in DBA/1 mice. Methods CIA was induced by chicken type Ⅱcollagen ( C Ⅱ) in DBA/1mice. Arthritis was evaluated by arthritis index. X-ray of the paws was taken. Histology pathology of ankles and spleen was observed and scored. Results Immunization d31,the paws of CIA mice appeared red and swelling,the scores of arthritis index increased,the period of swelling peak was from d40 to d60; immunization d35,the weight of CIA mice began to decrease. X-ray of paws showed that the paw joints of CIA mice deformed,and there was osteophyte formation associated with osteolysis. Histo-logical pathology of ankle joints showed that the synovium of CIA mice were hyperplasia,cartilage was destroyed,pannus was formed,and inflammatory cells infiltrated into synovium. Histological pathology of spleen showed more germinal centers and lymphoid follicular hyperplasia were observed,cell density of lymphatic sheath increased,scores of ankle joints and spleen histological pathology in CIA mice were higher than those in normal mice significantly. Conclusions The methods of CIA model induced by chicken C Ⅱ in DBA /1 mouse were reliable and reproducible. CIA incidence was high. Arthritis index,X-ray of paws,ankle joints and spleen histological pathology and so on were the principal indexes of evaluation for CIA model.
