Hypoxia-inducibIe factor-1(HIF-1)is a main nucIear transcription factor for response to intratumor hypoxia. RecentIy,it has become a hot spot to attempt to improve hypoxia by inhibiting HIF-1. HIF-1 inhibitors' mechanisms of action are wide,which infIuences the two signaI transduction pathways that are phosphatidyIinositoI-3-kinase/ protein kinase B/ mammaIian target of rapamycin and Ras/ Raf/ mitogen-activated protein kinase kinase1-2/ extraceIIuIar signaI-reguIated kinase1-2,inhibits the function of heat shock protein 90,and reduces transcriptionaI activity of HIF-1. In combination with radiation,HIF-1 inhibi-tors significantIy enhance radiosensitivity and weaken radioresistance of hypoxia ceIIs,which contributes to the therapeutic effect of tumor irradiation.

Clostridium perfringens is a common Gram-positive anaerobic conditioned pathogen,widely existing in nature,which can cause diarrhea,gas gangrene,and other diseases.Antibiotics are used in the clinical treatment of Clostridium perfringens infection,but the bacteria will devel-op resistance through mutation,drug-resistant plasmid transmission,and other ways,so that Clos-tridium perfringens can survive under the environmental pressure of antibiotics.Therefore,it is very important to find and develop new preparations to replace antibiotics or as feed additives to target the removal of Clostridium perfringens from the body or to prevent infection.In this study,a virulent Clostridium perfringens phage vB_CPP_AT was isolated from sewage by double plate method.The morphology of the bacteriophage was observed by transmission electron microscope.The biological characteristics of the bacteriophage were analyzed by lytic spectrum,MOI,pH,and temperature tolerance.The results showed that the vB_CPP_AT belongs to the Podoviridae.It would grow explosively at 60 min with an optimal MOI of 0.1.The vB_CPP_AT only lyse Clos-tridium perfringens and the lytic rate was 40％(8/20).No cleavage reaction occurred with other bacteria tested.The phage had good thermal stability and acid-base tolerance.Genomic analysis re-vealed that the phage had double-stranded DNA with a total length of 16 790 bp,and 20 open read-ing frames.Genomic analysis of vBCPPAT showed that it was a new virulent phage of Clostridi-um perfringens.The results laid a foundation for the clinical treatment of Clostridium perfringens with phage.

OBJECTIVE：To investigate the r ole of clinical pharmacists on the therapy for human herpesvirus 7（HHV-7） infection in central nervous system. METHODS ：The clinical pharmacists participated in the treatment process of the hospitalized patient who was a 15-year-old patient with central nervous system infection. The doctor initially gave Levetiracetam tablets （500 mg，bid，po）to control epilepsy symptoms ，and Acyclovir for injection （500 mg，q8 h，ivgtt）for antiviral treatment. According to the large red wheal scattered rubella on the limbs and back of the patient ，clinical pharmacists recommended to give Dexamethasone sodium phosphate injection （10 mg，qd，iv）and Loratadine tablets （10 mg，qd，po）for anti-allergy treatment ；in view of involuntary shaking of limbs in the patient ，clinical pharmacists recommended to continue to give Dexamethasone sodium phosphate injection intravenously to control inflammation and Xingnaojing injection （20 mL，qd，ivgtt） to improve the convulsion. For HHV- 7 infection，based on consulting the relevant guidelines and existing treatment experience ，the clinical pharmacists recommended discontinuation of acyclovir ， dexamethasone combined with Human immunoglobulin （pH 0278）（17.5 g，qd，ivgtt）for impact therapy should be used and adverse drug reactions and therapeutic effects should be monitored at the same time. RESULTS ： The physiciansaccepted the suggestions of clinical pharmacists. The patient was improved and discharged from the hospital after 18 days of treatment. CONCLUSIONS ： During the treatment of ineffective case of clinic rare central nervous system infectious diseases with routine a ntiviral drugs ，clinical pharmacists assisted physicians to improve their treatment plan and ensure the effectiveness and safety of patient ’s medication.

The local microenvironment is essential to stem cell-based therapy for ischemic stroke, and spatiotemporal changes of the microenvironment in the pathological process provide vital clues for understanding the therapeutic mechanisms. However, relevant studies on microenvironmental changes were mainly confined in the acute phase of stroke, and long-term changes remain unclear. This study aimed to investigate the microenvironmental changes in the subacute and chronic phases of ischemic stroke after stem cell transplantation. Herein, induced pluripotent stem cells (iPSCs) and neural stem cells (NSCs) were transplanted into the ischemic brain established by middle cerebral artery occlusion surgery. Positron emission tomography imaging and neurological tests were applied to evaluate the metabolic and neurofunctional alterations of rats transplanted with stem cells. Quantitative proteomics was employed to investigate the protein expression profiles in iPSCs-transplanted brain in the subacute and chronic phases of stroke. Compared with NSCs-transplanted rats, significantly increased glucose metabolism and neurofunctional scores were observed in iPSCs-transplanted rats. Subsequent proteomic data of iPSCs-transplanted rats identified a total of 39 differentially expressed proteins in the subacute and chronic phases, which are involved in various ischemic stroke-related biological processes, including neuronal survival, axonal remodeling, antioxidative stress, and mitochondrial function restoration. Taken together, our study indicated that iPSCs have a positive therapeutic effect in ischemic stroke and emphasized the wide-ranging microenvironmental changes in the subacute and chronic phases.
