OBJECTIVE To provide a reference for pharmaceutical care in patients with decompensated cirrhosis complicated with Clostridioides difficile splenic abscess. METHODS Clinical pharmacists participated in the whole-process pharmaceutical care of one patient with the above complex conditions. Retrieved from CNKI， Wanfang Data， VIP， PubMed， Embase and Web of Science databases，relevant literature about C. difficile splenic abscess was collected and analyzed. RESULTS Based on the results of metagenomic next-generation sequencing，imaging characteristics， and tissue penetration of antimicrobial agents， the clinical pharmacist suggested switching from ceftriaxone combined with metronidazole to intravenous vancomycin combined with metronidazole. For the hypokalemia that developed in the patient， the clinical pharmacist suggested discontinuing Furosemide tablets and adding Potassium citrate granules. When the p atient requested hospital discharge， the clinical pharmacist developed a post-discharge medication education plan. The physician adopted the clinical pharmacist’s recommendations. The patient improved after treatment without renal injury. Results of the literature analysis showed that among 11 involved patients，there were 9 males and 2 females，aged 32 to 90 years old，8 patients had a history of C. difficile infection. Vancomycin and metronidazole constituted the primary anti-infective regimens， and 3 patients died after treatment. CONCLUSIONS The clinical pharmacists ensured patients’ medication safety through pharmaceutical interventions including identifying the pathogen， optimizing anti-infective regimens， monitoring adverse drug reactions， and formulating a discharge medication education plan.

ObjectiveTo explore the clinical characteristics and risk factors for 30-day mortality in hospitalized patients with bloodstream infections (BSI) caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). MethodsData were obtained retrospectively from the electronic medical records of inpatients at a tertiary A-grade hospital in Shanghai from January 2016 to December 2023. The collected variables included age, gender, department, surgical treatment, empirical antibiotic therapy, Pitt Bacteremia score (PBS), Charlson comorbidity index (CCI), INCREMENT-CPE score (ICS), length of hospital stay, the time from CRKP-BSI to discharge and, etc. The follow-up period ended upon discharge, with the follow-up outcomes defined as in-hospital mortality or discharge. The endpoint was defined as death within 30 days (including day 30) caused by CRKP-BSI or infection-related complications. Patients who survived within 30 days after CRKP-BSI were classified into the survival group, while those who died within 30 days were classified into the death group. Independent risk factors for 30-day mortality in patients with CRKP-BSI were analyzed using univariate and multivariate Cox regression analysis. ResultsA total of 71 hospitalized patients with CRKP-BSI, comprising 51 males and 20 females, with an average age of (65.12±18.25) years, were included during the study period. The M (P₂₅, P₇₅) of hospital stay were 37.00 (24.00, 56.00) days, and M (P₂₅, P₇₅) of the duration from CRKP-BSI to discharge or death were 18.00 (7.00, 35.00) days. There were 20 deaths (28.17%) in the death group and 51 survivors (71.83%) in the survival group. The results of multivariate Cox regression analysis showed that the ICS as an independent risk factor for 30-day mortality in CRKP-BSI patients (HR=1.379, 95%CI: 1.137‒1.671, P=0.001). Each 1-point increase in the ICS was associated with a 37.9% increase in the risk of mortality. ConclusionThe ICS is found to be a risk factor for 30-day mortality in patients with CRKP-BSI, which may facilitate the prediction for the risk of 30-day mortality and thereby support clinical decision-making for patients with CRKP-BSI.

Objective To explore the biological functions and mechanisms of PIWI-interacting RNA(piRNA)in cervical cancer(CC).Methods RT-qPCR was used to detect the expression level of piRNA-2732 in CC tissue,CaSki cells and End1/E6E7 cells.EpiQuik m6A RNA methylation quantification kit was used to detect the methylation level of m6A RNA in CaSki cells.The expression levels of methyltransferases(METTL3,METTL14 and WTAP)and demethylases(FTO,ALKBH5)mRNA in CaSki cells were detected by RT-qPCR.After culturing CaSki cells to logarithmic growth stage,they were divided into six groups:piRNA-2732 mimic negative control group(mi-NC group),piRNA-2732 mimic group(mi-2732 group),piRNA-2732 inhibitor negative control group(in-NC group),piRNA-2732 inhibitor group(in-2732 group),piRNA-2732 mimic+METTL3 knockdown control group(mi-2732+si-NC group),and piRNA-2732 mimic+METTL3 knockdown group(mi-2732+si-METTL3 group).The viability of CaSki cells was detected by CCK8 assay.Colony formation assay was used to detect the proliferation ability of CaSki cells.Transwell experiment was used to detect the migration and invasion ability of CaSki cells.RT-qPCR and Western blot were used to detect the expression of methyltransferase like protein 3(METTL3).Transfected METTL3 wild-type(METTL3-WT)and METTL3 mutant(METTL3-MUT)in the mi-NC group,mi-2732 group,in-NC group,and in-2732 group respectively,and detected the effect of piRNA-2732 on METTL3 through dual luciferase reporter gene assay.Results Compared with the adjacent tissues,the expression of piRNA-2732(3.84±1.08 vs 1.32±0.53)was significantly higher in the cancer tissues of CC patients,and the difference was statistically significant(t=5.115,P<0.001).Compared with end1/E6E7 cells,the expression of piRNA-2732(1.00±0.13 vs 1.67±0.16)in CaSki cells was significantly higher,and the difference was statistically significant(t=5.632,P<0.01).Compared with mi-NC group,mi-2732 group promoted the viability,proliferation,migration and invasion of CaSki cells,and the differences were statistically significant(t=4.410～11.040,all P<0.01).Compared with mi-NC group,mi-2732 group increased m6A RNA methylation level and METTL3 mRNA and protein,the differences were statistically significant(t=6.176,9.211,12.550,all P<0.05).The results of dual luciferase reporter gene testing showed that compared with the mi-NC+METTL3-WT group,the relative luciferase activity of mi-2732+METTL3-WT group was significantly increased(t=11.850).Compared with mi-2732+METTL3-WT group,the relative luciferase activity of mi-2732+METTL3-MUT group was significantly lower(t=12.740),and the difference was statistically significant(all P<0.000 1).Compared with in NC+METTL3-WT group,the relative luciferase activity of in-2732+METTL3-WT group was significantly lower(t=7.828),compared with in-2732+METTL3-WT group,the relative luciferase activity of CaSki cells in in-2732+METTL3-MUT group was significantly increased(t=8.146),and the difference was statistically significant(all P<0.001).Compared with mi-2732+si-NC group,the expression level of m6A in mi-2732+si-METTL3 group was significantly lower,and the difference was statistically significant(t=7.630,P<0.01).Compared with mi-2732+si-NC group,the proliferation ability,colony number,cell migration and invasion ability of CaSki cells in mi-2732+si-METTL3 group were significantly decreased,and the differences were statistically significant(t=3.695～4.891,all P<0.001).Conclusion piRNA-2732 is overexpressed in CC tissues and cells,and piRNA-2732 promotes tumor development in CC through METTL3 mediated m6A methylation.

Objective:To analyze the genetic characteristics of clinical manifestations in children with KBG syndrome due to microdeletions.Methods:A retrospective case summary was conducted. Four children diagnosed with KBG syndrome due to 16q24.3 microdeletion at Children′s Hospital of Zhengzhou University from July 2021 to April 2024 were enrolled.Their clinical manifestations, biochemical parameters, imaging data, whole-exome sequencing results, treatments and follow-up outcomes were reviewed.Results:The cohort included two males and two females (diagnosed at 81, 18, 26, and 56 months of age, respectively), from four unrelated families. All patients exhibited peculiar facial features (Cupid′s bowed-shaped lips, prominent ears, thick eyebrows), skeletal abnormalities (brachydactyly, abnormal ribs, short stature, etc.), ocular anomalies (astigmatism, strabismus, amblyopia, etc.), intrauterine growth restriction, and developmental retardation. Case 2, 3, 4 had cranial imaging abnormalities, including thin anterior pituitary lobes with pineal cyst, left ventricular cyst, and abnormal pituitary stalk or lateral ventricles with sinusitis, respectively. Two children had intellectual disability, two had congenital heart disease, and one had delayed bone age and hair abnormalities. Whole exome genomic sequencing confirmed 16q24.3 microdeletions encompassing ANKRD11 gene in all four cases. Two children treated with recombinant human growth hormone achieved height increments of 1.5 s and 0.4 s, respectively. Conclusions:Typical features of 16q24.3 microdeletion-induced KBG syndrome include peculiar facial features, macrodontia, skeletal anomalies, neurological abnormalities, and ocular defects. Genetic testing is essential for definitive diagnosis. The treatment of KBG syndrome requires early diagnosis and multidisciplinary collaboration to implement individualized treatment for multisystem symptoms.

Objective:To investigate the role of vitamin E succinate (VES) in inducing autophagy of human gastric cancer cells by activating calcium redistribution through inositol 1, 4, 5-trisphosphate receptors (IP 3R) pathway. Methods:Human gastric cancer lines MKN28 (moderately differentiated) and MKN45 (poorly differentiated) cells were cultured in vitro in March 2022. Gastric cancer cells were treated with VES at different doses for 24 h, and cell viability was measured by CCK-8 method to determine VES dose for subsequent study. The experiment was set up with solvent control group (0.1% ethanol), VES dose groups, 100 nmol/L rapamycin (RAPA) as autophagy positive control group (RAPA group), 15 μg/ml tunicamycin (TM) was used as the endoplasmic reticulum stress (ERS) positive control group (TM group), 10 μmol/ml 2-aminoethyl diphenylborinate (2-APB group) was used to inhibit IP 3R (2-APB group) and VES+2-APB group. The occurrence of autophagosomes in gastric cancer cells was observed by transmission electron microscopy, and microtubule associated protein 1 light chain 3 (LC3), Beclin1, IP 3R, glucose-regulated protein 75 (Grp75), voltage-dependent anion channel 1 (VDAC1) protein expression was detected by western blotting. Fluo-4 AM was used to label intracellular calcium ions, Rhod-2 AM was used to label mitochondrial calcium ions, and the fluorescence intensity of calcium ions was observed by fluorescence microscope. One-way analysis of variance was used to compare the means among multiple groups, and LSD- t method was used for pairwise comparison. Results:CCK-8 results showed that compared with solvent control group, the proliferation rates of MKN28 cells in 10-100 μg/ml VES group and MKN45 cells in 20-100 μg/ml VES group were significantly decreased ( P<0.05). Subsequent VES dosages were determined according to the growth curve, MKN28 was 5, 10, 20, 40 μg/ml, and MKN45 was 10, 20, 40, 80 μg/ml. The results of transmission electron microscopy and fluorescence showed that autophagosomes were formed in MKN28 cells in 5 and 20 μg/ml VES groups and MKN45 cells in 10 and 40 μg/ml VES groups, and the fluorescence intensity of calcium ions in cytoplasm and mitochondria was significantly higher than that in solvent control group ( P<0.05). Compared with solvent control group, LC3, Beclin1, IP 3R, Grp75 and VDAC1 protein expressions of MKN28 cells in 20 and 40 μg/ml VES groups and MKN45 cells in 40 and 80 μg/ml VES groups were significantly increased ( P<0.05). After inhibiting IP 3R with 2-APB, the expression levels of IP 3R, Grp75 and VDAC1 in two kinds of gastric cancer cells in VES+2-APB group were significantly decreased compared with VES group ( P<0.05). The fluorescence results showed that the fluorescence intensity of cytoplasmic and mitochondrial calcium ions in VES+2-APB groups was significantly lower than that in VES group ( P<0.05). Compared with VES group, LC3 and Beclin1 protein expressions in two kinds of gastric cancer cells in VES+2-APB groups were significantly decreased ( P<0.05) . Conclusion:VES may activate intracellular calcium redistribution through IP 3R-Grp75-VDAC1 calcium channel and induce autophagy in gastric cancer cells.

Objective:To explore the psychological acceptance mechanism of appropriate Traditional Chinese Medicine (TCM) techniques among patients with abnormal uterine bleeding (AUB) .Methods:Using purposive sampling, AUB patients experiencing menstruation but not yet menopausal were recruited from Zhumadian City, Henan Province, and Jiaxing City, Zhejiang Province, between November 2022 and January 2023. Semi-structured interviews were conducted, and the collected data were analyzed using content analysis.Results:A total of four main themes were identified: individualized disease perception and treatment experience; awareness and treatment experience of appropriate TCM techniques; cultural identity and influence of traditional beliefs; and the need for science communication and safety regarding TCM techniques.Conclusions:While AUB patients show a generally high level of acceptance toward appropriate TCM techniques, their understanding of both AUB and the relevant TCM therapies remains limited. Multiple factors influence patients' choices, and some concerns and doubts still persist during the decision-making process.

Objective:To analyze the epidemic trend of influenza-like illness（ILI）cases，etiological detection results，and the evolution of the hemagglutinin（HA）gene of the predominant strains in Hanzhong City，Shaanxi Province during the 2018-2024 influenza seasons.Methods:ILI sentinel surveillance data and network laboratory test results during the 2018-2024 influenza seasons in Hanzhong City，Shaanxi Province were collected for descriptive analysis. The HA gene sequences of 25 predominant strains were obtained through whole-genome deep sequencing method，and then compared with the vaccine strains recommended by the World Health Organization in the same period to analyze the evolution of the virus.Results:A total of 37 770 cases of ILI were reported in Hanzhong City during the 2018-2024 influenza seasons，and the proportion of total ILI cases（ILI%）was 2.87%（37 770/1 316 009）. The epidemic trend of ILI showed an obvious epidemic peak in winter and spring（from December of the current year to March of the following year）. The specimens with the highest positive rate were of type A（H3N2）（39.12%，365/933），and the predominant epidemic strains in each influenza season alternated among A（H1N1）pdm09（in the 2018-2019 and 2022-2023 influenza seasons），A（H3N2）（in the 2019-2020 and 2023-2024 influenza seasons）and B（Victoria）（in the 2021-2022 influenza season）. The phylogenetic relationship gradually became more distant over time across different influenza seasons. Among them，the epidemic strains of A（H1N1）pdm09 belonged to the 6B.1 clade，and the evolution mainly occurred in the Sa and Sb regions of the HA epitope. Meanwhile，the epidemic strains of A（H3N2）belonged to the 3C clade，and the evolution mainly took place in the A，B and C regions of the HA epitope. The strains of the B（Victoria）lineage belonged to the V1a.3a.2 clade，and the evolution mainly occurred in the 120-loop，150-loop，and 190-helix regions of the HA epitope.Conclusions:The influenza epidemic in Hanzhong City has obvious seasonality，and the amino acids of the epidemic strains have shown a certain degree of variation over the years. In future prevention and control work，influenza surveillance should be continuously strengthened，and the change trend of the predominant circulating strains should be closely monitored.
