ABSTRACT
OBJECTIVE To compare efficacy and safety of continuous pump versus intermittent infusion of amphotericin B in the treatment of invasive fungal infection， and to provide evidence-based reference for clinical treatment. METHODS Retrieved from PubMed， the Cochrane Library， Web of Science， Embase， Wanfang， CNKI， CBM and VIP database， randomized controlled trial （RCT） and cohort study about 24 h continuous pump （trial group） versus intermittent infusion （control group） of amphotericin B were collected from the inception to Jan. 2023. After literature screening and data extraction， the quality of RCT was evaluated with modified Jadad scale， and the quality of cohort study was evaluated with Newcastle-Ottawa scale. Meta-analysis and sensitivity analysis were performed by using RevMan 5.4 software. RESULTS A total of 7 literature were included， involving 1 RCT and 6 cohort studies with a total of 767 patients. The results of meta-analysis showed that the clinical effective rate [RR＝1.44， 95%CI （1.13，1.83）， P＝0.003] of trial group was significantly higher than that of control group， and all-cause mortality rate [RR＝0.37， 95%CI（0.19，0.72），P＝0.003] and the incidence rate of infusion reaction [RR＝0.28，95%CI（0.18，0.43）， P＜0.000 01] were significantly lower than control group； there was no statistical significance in the incidence rate of renal impairment between 2 groups [RR＝0.71，95%CI（0.45，1.11），P＝0.13] . The sensitivity analysis results showed that the results obtained in this study were robust. CONCLUSIONS The efficacy and safety of 24 h continuous pump of amphotericin B are better than those of intermittent infusion in the treatment of invasive fungal infection.
ABSTRACT
Astrocytes (ASTs) and oligodendroglial lineage cells (OLGs) are major macroglial cells in the central nervous system. ASTs communicate with each other through connexin (Cx) and Cx-based network structures, both of which allow for quick transport of nutrients and signals. Moreover, ASTs interact with OLGs through connexin (Cx)-mediated networks to modulate various physiological processes in the brain. In this article, following a brief description of the infrastructural basis of the glial networks and exocrine factors by which ASTs and OLGs may crosstalk, we focus on recapitulating how the interactions between these two types of glial cells modulate myelination, and how the AST-OLG interactions are involved in protecting the integrity of the blood-brain barrier (BBB) and regulating synaptogenesis and neural activity. Recent studies further suggest that AST-OLG interactions are associated with myelin-related diseases, such as multiple sclerosis. A better understanding of the regulatory mechanisms underlying AST-OLG interactions may inspire the development of novel therapeutic strategies for related brain diseases.

OBJECTIVE To provide ideas for pharmaceutical care of Mycobacterium abscess infection. METHODS The diagnosis and treatment plan ，about a patient with M. abscess infection after resection of intervertebral neurilemmoma participated by clinical pharmacists ，was analyzed . According to the results of bacterial culture and drug sensitivity test of wound secretion ，the clinical pharmacist timely dealed with the adverse drug reactions during the treatment . For the tinnitus caused by the patient taking amikacin（0.4 g，intravenous drip ，q12 h），it was suggested to stop amikacin and replace it with linezolid ；however，the patient suffered from knee pain after taking linezolid . The clinical pharmacist once again suggested stopping linezolid ，continuing to use amikacin，and adjusting the dose to 0.8 g，intravenous drip ，q24 h；at the same time ，the patients were given medication guidance and ordered to have regular follow -up after discharge . RESULTS The physicians adopted the suggestions of clinical pharmacists ， and the patient did not suffer from tinnitus ，knee pain and other discomfort ，and the liver and kidney functions were normal . CONCLUSIONS Clinical pharmacists timely assist clinicians to adjust the medication plan ，which improves the effectiveness and safety of patients ’medication.
ABSTRACT
The corona virus disease 2019 (COVID-19), which started in Wuhan in December 2019, is a new infectious disease. The disease is highly contagious, and the correct selection of effective disinfectants is essential. This article analyzed the environmental resistance of coronavirus and its sensitivity to commonly used disinfectants by reviewing domestic and foreign literatures, and concluded that coronavirus has strong survivability in the environment, but it can be efficiently inactivated by most disinfectants. However, it should be noted that the commonly used concentration of chlorine-containing disinfectants (effective chlorine concentration of 500 mg/L) cannot quickly kill coronavirus, and a concentration of 1 000 mg/L or higher is required. Other biocidal agents, such as benzalkonium chloride and chlorhexidine digluconate, are less effective. This article aimed to provide references for selecting the appropriate disinfectants and disinfection methods to cut off the spread of the virus.
