Objective To explore the active monitoring strategies for hypoglycemia in hospitalized dia-betic patients,as well as their clinical symptom characteristics and influencing factors.Methods A retrospec-tive search was conducted on all inpatients in a tertiary hospital in 2023.The hospital's electronic medical re-cord system was manually retrieved through the inpatient numbers of the patients.Adult inpatients with dia-betes who experienced hypoglycemia were included as the research subjects,and the general conditions and possible hypoglycemia-related risk factors were collected.Embed the hypoglycemic electronic trigger program in China Hospital Pharmacovigilance System(CHPS),reviewed the original medical records of patients with positive trigger triggering,and calculated the positive predictive value(PPV).Searched for the number of hy-poglycemic adverse reaction cases voluntarily reported by this hospital during the same period from National Adverse Reaction Monitoring System and compared with the actual number of hypoglycemic cases discovered.Patients with suspected drug-induced hypoglycemia were divided into the symptomatic group and the asymp-tomatic group based on whether they presented hypoglycemia-related symptoms.Multivariate logistic regres-sion analysis was applied to analyze the influencing factors.Results A total of 1 001 adult hospitalized diabet-ic patients with hypoglycemia were included in the study.Among them,725 cases were suspected of drug-in-duced hypoglycemia,and 495 cases were suspected of hypoglycemia caused by drug interactions.After manual review,131 cases of drug-induced hypoglycemia patients had clinical symptoms,and hypoglycemic adverse re-action events should be reported,PPV of this trigger for symptomatic hypoglycemia was 18.1%(131/725).However,the number of hypoglycemic adverse reactions spontaneously reported through National Adverse Reaction Monitoring System by this hospital during the same period was 4 cases,and the reporting rate was only 3.1%(4/131).Multivariate logistic regression analysis showed that aging and grade 2 hypoglycemia were risk factors for the occurrence of related symptoms in patients with suspected drug-induced hypoglycemia(P<0.05),while surgery,type 2 glucosuria,unclassified diabetes,and the use of insulin secretagogues were protective factors(P<0.05).Conclusion Drug-induced hypoglycemia dominates among hospitalized diabetic patients,and age,hypoglycemia grade,inpatient department using insulin secretagogues,diabetes diagnosis and classification are closely related to the occurrence of clinical hypoglycemia-related symptoms.Active monito-ring through CHPS can effectively increase the detection rate and reporting rate of hypoglycemic adverse e-vents in hospitalized diabetic patients.

The identification of oleaginous yeast species capable of simultaneously utilizing xylose and glucose as substrates to generate value-added biological products is an area of key economic interest. We have previously demonstrated that the Cutaneotrichosporon dermatisNICC30027 yeast strain is capable of simultaneously assimilating both xylose and glucose, resulting in considerable lipid accumulation. However, as no high-quality genome sequencing data or associated annotations for this strain are available at present, it remains challenging to study the metabolic mechanisms underlying this phenotype. Herein, we report a 39,305,439 bp draft genome assembly for C. dermatis NICC30027 comprised of 37 scaffolds, with 60.15% GC content. Within this genome, we identified 524 tRNAs, 142 sRNAs, 53 miRNAs, 28 snRNAs, and eight rRNA clusters. Moreover, repeat sequences totaling 1,032,129 bp in length were identified (2.63% of the genome), as were 14,238 unigenes that were 1,789.35 bp in length on average (64.82% of the genome). The NCBI non-redundant protein sequences (NR) database was employed to successfully annotate 11,795 of these unigenes, while 3,621 and 11,902 were annotated with the Swiss-Prot and TrEMBL databases, respectively. Unigenes were additionally subjected to pathway enrichment analyses using the Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Cluster of Orthologous Groups of proteins (COG), Clusters of orthologous groups for eukaryotic complete genomes (KOG), and Non-supervised Orthologous Groups (eggNOG) databases.Together, these results provide a foundation for future studies aimed at clarifying the mechanistic basis for the ability of C. dermatis NICC30027 to simultaneously utilize glucose and xylose to synthesize lipids.

OBJECTIVE:To study the effects and mechanism of oncolytic virus M 1(called M 1 virus for short )inducing the apoptosis of cervical cancer C-33A cells. METHODS :MTT assay was used to detect survival rate of C- 33A cells that were treated with different titers (0,0.001,0.01,0.1,1,10 PFU/cell)of M 1 virus. C- 33A cells were divided into control group (0 PFU/cell), low-dose,medium-dose and high-dose groups of M 1 virus(0.001,0.01,0.1 PFU/cell). After treated with corresponding titers of M1 virus for 48 h,flow cytometry was used to detect the apoptotic rate and infection rate of cells;Western blot was performed to detect the protein expression of C/EBP homologous proteins (CHOP),caspase-12,caspase-3 and cleaved-caspase- 3. RESULTS : After treated with different titers of M 1 virus,the survival rate of C- 33A cells decreased significantly (P<0.01),and showed a dose-dependent tr end. Compared with control group ,the apoptotic rate and infection rate of cells in M 1 virus groups as well as the protein expression of CHOP ,caspase-12 and cleaved-caspase- 3(except for medium-dose group )in M 1 virus medium-dose and high-dose groups were increased significantly (P<0.01). CONCLUSIONS :M1 virus can induce the apoptosis of cervical cancer C-33A cells ,and its mechanism may be related to the activation of endoplasmic reticulum stress pathway.

Objective To prepare polypeptide nerve growth factor (NGF) thermosentitive gel and observe drug release in vitro,in order to provide scientific information for biopharmaceuticals delivery system design aiming to treat the inner disease.Methods The thermosensitive in situ gel was prepared with NGF as main component and Pluronic F127 as the gel matrixes.The effect of concentration of gel matrix PF127 on lower critical solution temperature(LCST) were investigated.In vitro release kinetic studies were performed using membraneless dissolution method and reversed-phase high performance liquid chromatography (HPLC) method was adopted to determine NGF content in the dissolution medium.Results The average LCST of NGF-loaded gel prepared by different concentration of PF127 was 28.48-36.26℃ and the gels had good stability.The in vitro release kinetics was well characterized by sustained release and can be fitted by zero order kinetics.The in vitro accumulated release ratio of NGF in the thermosensitive gel reached to above 95%.hβ-NGF loaded in higher PF127 gel resulted in a more sustained release of hβ-NGF from the thermosensitive gel.Conclusion Well-prepared NGF thermosensitive gel is a promising inner ear-oriented drug delivery system for treating deafness and deserves to further development.
