The nursing experience was summarised over a patient who developed an impending myasthenic crisis following immune checkpoint inhibitors(ICIs)therapy after the surgery for stage-Ⅳ liver cancer.Key nursing points included:close monitoring for early signs of impending myasthenic crisis;set up a multi-disciplinary team to improve respiratory,oropharyngeal and ocular function,control respiratory infection,provide psychological support in order to prevent the patient from developing a manifest myasthenia-gravis crisis(MC);combine with medications to relieve myasthenic symptoms and prevent adverse drug reactions;individualised rehabilitation training to promote recovery of muscular strength.Eventually,the patient did not develop into a MC during hospitalisation(20d)and was well at 3-month after discharge.

Objective To investigate the mechanism of mitochondrial autophagy regulating the expression of NLRP3 inflammasome in prostate tissue in experimental autoimmune prostatitis(EAP)rats and to provide a theoretical basis for the study of new drug development.Methods A numerical table of 40 SD male rats was randomly divided into 8 groups.Namely,normal group(N),model group(M),rapamycin group(RAP),rapamycin+mitochondrial autophagy inhibitor group(RAP+Mdivi-1),autophagy inhibitor group(3MA),mitochondrial autophagy inhibitor group(Mdivi-1),Caspase1 inhibitor group(Caspase1),NLRP3 inhibitor group(NLRP3),5 animals per group.After drug intervention,HE staining,immunofluorescence,colorimetry,and WB method were used to observe the relevant indexes.Results Compared with group N,the structural damage of prostate gland was obvious in group M.Compared with the M group,the prostate gland structure in RAP group,Caspase-1 group and NLRP3 group were improved.However,that in 3-MA group and Mdivi-1 group was not improved,and even destroyed more obvi-ously.Compared with group N,the co-expression of LC3-II and LAMP-1 was enhanced,mitochondrial membrane potential was decreased,ROS release level was significantly increased in prostate tissue of rats in group M.Com-pared with the M group,the above indexes in RAP group and NLRP3 group were significantly improved.However,the above indexes in 3-MA group and Mdivi-1 group became worse.Compared with group N,the protein expressions of DRP1,PINK1 and Parkin in prostate mitochondria of rats in group M were increased,and the protein expres-sions of OPA1 was decreased.Compared with group M,the protein expressions of DRP1,PINK1 and Parkin in RAP group and NLRP3 group were significantly increased,while those in 3-MA group and Mdivi-1 group were sig-nificantly decreased.OPA1 protein expression was significantly decreased in the RAP group.The protein expression of Parkin in Caspase-1 group was decreased,but the protein expression of DRP1,OPA1 and PINK1 had no significant difference.Compared with group N,the protein expressions of LC3II/LC3I,Beclin1,NLRP3,ASC,Cleaced-Caspase1,Cleaced-IL-1β,and IL-18 in prostate tissue of rats in group M were increased,while the protein expres-sions of P62 was decreased.Compared with M group,LC3II/LC3I and Beclin1 protein expressions in RAP group and NLRP3 group were significantly increased,while those in 3-MA group and Mdivi-1 group were significantly decreased.Compared with M group,P62,NLRP3,ASC,Cleaced-Caspase1,Cleaced-IL-1β and IL-18 protein expressions in RAP group and NLRP3 group were significantly decreased,while those in 3-MA group and Mdivi-1 group were significantly increased.Compared with M group,the protein expressions of NLRP3,ASC,Cleaced-Caspase1,Cleaced-IL-1β,and IL-18 in Caspase-1 group were significantly reduced,but the protein expressions of LC3Ⅱ/LC3Ⅰ,Beclin1,and P62 were not statistically significant.Conclusions NLRP3 inflammatosome is involved in the progression of chronic prostatitis in EAP rats.Mitochondrial autophagy mediates the occurrence and development of prostatitis in EAP by regulating the activation of NLRP3 inflammasome in prostate tissue.

Objective To study the spatial correlation characteristics of the number of large medical equipment alloca-tion in China's provinces and cities,with a view to providing a reference basis for the optimization of the allocation of large medical equipment.Methods It analyzed the spatial autocorrelation of China's large medical equipment alloca-tion and its influencing factors by using the Moran's I,grey correlation and other methods.Results The results of the spatial autocorrelation analysis showed that the allocation of large medical equipment in China was positively corre-lated spatially,and the spatial agglomeration was significant(Global Moran's I index value was 0.392,P＜0.05).The grey correlation of GDP,year-end resident population,geographic area,number of tertiary hospitals,number of beds in medical institutions,number of practicing(assistant)physicians,and annual discharges in each province and city were 0.913,0.919,0.745,0.883,0.907,0.929,0.880,respectively.Conclusion China's large-scale medi-cal equipment configuration of spatial autocorrelation properties,distributed in the eastern Beijing-Tianjin-Hebei,Yangtze River Delta region and some provinces and cities in the west of the large-scale medical equipment configura-tion level in the formation of high-value agglomeration and low-value agglomeration area respectively.At the same time,the equipment configuration has the characteristics of high-quality medical resources concentration,oriented to the needs of the masses,taking into account economic and social development,etc.It is recommended to fur-ther optimise the spatial structure of equipment allocation,incorporate the configuration of large-scale medical equip-ment into the consideration of regional health resource planning at all levels,and enhance the linkage of the equip-ment configuration planning between provinces and cities.

Objective To evaluate the role of remimazolam in lipopolysaccharide(LPS)-induced M1 microglial polarization and its relationship with Toll-like receptor 4(TLR4).Methods BV2 mi-croglia cells were randomly divided into 5 groups(n=20):control group,LPS group(1 μg/ml for 24 h),remimazolam+LPS group(remimazolam group,pretreated with 100 μg/ml remimazolam for 20 min followed by LPS),remimazolam+LPS+Neoseptin-3 group(agonist group,50 pmol Neoseptin-3 dissolved in DMSO),and remimazolam+LPS+DMSO group(agonist control group).The contents of TNF-α and IL-1β in the supernatant were detected by ELISA.The expres-sion of M1 microglia markers,inducible nitric oxide synthase(iNOS)and TLR4 at mRNA.Immu-nofluorescence staining was employed to identify the location of iNOS.Results When compared to the control group,the contents of TNF-α and IL-1β in the supernatant and the expression of iNOS[(14.757±0.986)％vs(1.561±0.08)％]and TLR4 at mRNA and protein levels were sig-nificantly higher in the other four groups(P＜0.05).Remimazolam treatment reversed the increa-ses of the TNF-α and IL-1β contents in the supernatant and mRNA and protein expression of iNOS[(3.767±0.364)％vs(14.757±0.986)％]and TLR4 induced by LPS(P＜0.05).In addi-tion,remimazolam agonist Neoseptin-3 restored the effects of LPS on above molecules[iNOS:(6.827±0.642)％vs(3.767±0.364)％,all P＜0.05].But,there were no statistical differences in above molecules between the agonist group and agonist control group(P＞0.05).Conclusion The mechanism by which remimazolam inhibits LPS-induced M1 microglial polarization is related to down-regulation of TLR4 expression.

Objective:To investigate the gene expression of pulmonary metastatic papillary thyroid cancer (PTC) and its association with lung metastasis, facilitating risk assessment and personalized therapeutic strategies.Methods:A retrospective cohort study was conducted on 269 PTC patients (61 males, 208 females, age (38.9±11.9) years) treated at the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University from January 2017 to June 2020, including 60 cases with lung metastasis and 209 without. Primary tumor tissues underwent targeted next-generation sequencing (tNGS). Univariate and multivariate logistic regression analyses were performed to identify risk factors for lung metastasis, and χ2 test was used to evaluate the differences between the effective and ineffective groups of radioactive iodine (RAI) therapy. Results:In 60 PTC patients with lung metastasis, the mutation rates of B-Raf proto-oncogene, serine/threonine protein kinase (BRAF) V600E, telomerase reverse transcriptase (TERT) promoter, and rearranged in transformation (RET) fusion mutations were 28.3%(17/60), 25.0%(15/60), and 26.7%(16/60), respectively. Univariate analysis demonstrated that age≥55 years, multifocality, lateral cervical lymph node metastasis, extrathyroidal extension, BRAF V600E mutation, RET fusion, and TERT promoter mutation were significantly associated with lung metastasis in PTC ( Wald χ2 values: 4.13-31.28, all P<0.05). However, no significant statistical associations were observed between lung metastasis and gender, rat sarcoma type GTPase family (RAS) mutation, tumor protein p53 (TP53) mutation, phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) mutation, neurotrophic tyrosine receptor kinase 1 (NTRK1) fusion, or anaplastic lymphoma kinase (ALK) fusion ( Wald χ2 values: 0.01-3.50, all P>0.05). Multivariate analysis identified TERT promoter mutation (odds ratio ( OR)=11.86, 95% CI: 3.68-38.29, P<0.001), multifocality ( OR=5.30, 95% CI: 2.41-11.69, P<0.001), extrathyroidal extension ( OR=3.98, 95% CI: 1.77-8.98, P=0.001), and lateral cervical lymph node metastasis ( OR=3.13, 95% CI: 1.28-7.68, P=0.013) as independent risk factors for lung metastasis in PTC. Conversely, BRAF V600E mutation emerged as a potential protective factor ( OR=0.09, 95% CI: 0.04-0.21, P<0.001). The proportions of BRAF V600E mutation ( χ2=20.49, P<0.001) and TERT promoter mutation ( χ2=4.91, P=0.027) were higher in the RAI ineffective group. Conclusions:BRAF V600E mutation, TERT promoter mutation and RET fusion are related gene expression in lung metastasis of PTC. Multifocality, extrathyroidal extension, lateral cervical lymph node metastasis and TERT promoter mutation are risk factors for lung metastasis of PTC (TERT is an independent molecular risk marker), while BRAF V600E mutation may be a protective factor. RAI treatment efficacy of PTC patients with lung metastasis and BRAF V600E mutation/TERT promoter mutation is worse.

Objective To understand the molecular epidemiological characteristics and hypervirulence evolution trend of ST11 carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from medical institutions in Shanghai,and provide scientific basis for formulating the prevention and control measures of drug-resistant organisms.Methods A total of 201 strains of CRKP isolated from 12 medical institutions in Shanghai from 2021 to 2022 were collected.Antimicrobial susceptibility testing and whole genome sequencing were performed.The concatenated data was used for multilocus sequencing typing(MLST),serum typing(wzi typing),as well as analysis of resistance and viru-lence genes.Results All 201 CRKP strains were multidrug-resistant organisms(MDROs).These strains were al-most completely resistant to carbapenems,cephalosporins,and quinolones.Drug resistance gene analysis showed that 93.03％of CRKP strains carried KPC gene.201 CRKP strains were divided into 6 ST types and 10 capsule wzi types,with ST11-KL64(n=104)being the dominant type,followed by ST15-KL19(n=54).52.24％(n=105)of CRKP carried rpmA/rpmA2+iucA+iutA+iroN genes.Conclusion CRKP isolated from medical institutions in Shanghai is mainly ST11-KL64 type with severe multidrug resistance,and more than half of the strains are hyper-virulent carbapenem-resistant Klebsiella pneumoniae(hv-CRKP).It is necessary to continuously strengthen the monitoring of the molecular characteristics of CRKP,so as to prevent outbreaks of healthcare-associated infection.
