Objective To evaluate the change of extended spectrum β-lactamase (ESBLs) Producing Klebsiella Pneumoniae (ESBLs-KPN) and Escherichia coli (ESBLs-ECO) causing nosocomial infection after antimicrobial intervention. Methods We regularly monitored the data on the yearly consumption [defined as daily dose (DDD) per 1 000 patient-days] of frequently used antibiotics from Dec. 2004 to Dec. 2007. From Jan. 2005 to Dec. 2007, we monitored the resistance of frequently used antibiotics and the timely integrative antimicrobial intervention was based on the outcome of antimicrobial resistance. We also monitored the isolation rate of ESBLs-KPN and ESBLs-ECO causing nosocomial infection. The departments studied were the experimental group and other comparable medical departments were the control group(ICU was excluded).Results The isolation rate of ESBLs-KPN ((43.90%)) and ESBLs-ECO (45.83%) in the experimental group was higher than that in the control group (28.04% and 24.90%, respectively) before the intervetion (P＜0.05). The isolation rate of ESBLs-KPN decreased (from 26.47% to 17.65%) in the experimental group and that in the control group increased ( ESBLs-KPN: from 34.18% to (52.94%;) ESBLs-ECO: from 47.13% to 63.78%) from 2005 to 2007 (P＜0.05). The isolation rate of ESBLs-KPN and ESBLs-ECO in the experimental group was lower than that in the control group after the antimicrobial intervention (P＜0.05). Usage of ceftazidime and cefoperazone/sulbactam and imipenem was reduced and the consumption of cefepime was increased in the experimental group ((P＜0.05)). Consumption of ceftazidime and cefoperazone/sulbactam and cefepime was increased. Conclusion The prevalence of ESBLs-KPN and ESBLs-ECO may be decreased after the integrative antimicrobial intervention.

OBJECTIVE To evaluate the relationships between antimicrobial usage and the isolated rate of ESBLs-KPN and ESBLs-ECO.METHODS We monitored the data on the yearly patient-days and the yearly consumption(defined daily dose(DDD) per 1000 patient days) frequent antibiotics and the isolated rate of ESBLs-KPN and ESBLs-ECO causing nosocomial infections from Jan 2004 to Dec 2007 was analyzed.RESULTS The yearly patient-days of our department significantly increased from 64 203 days in 2004 to 74 442 days in 2007(P

Objective To explore the altered functional connectivity of the amygdala in adolescents with internet gaming disorder (IGD) using resting state functional connectivity (rsFC) and dynamic functional connectivity (dFC) analysis.Methods Thirty adolescents with IGD (IGD group) and 30 demographically matched healthy controls (HC group) were recruited.The right and left amygdala were selected as seed regions,the rsFC and dFC between 2 groups were calculated.The regions showing altered connectivity in IGD were adopted as ROIs for correlation analysis.Results Compared to HC group,IGD group had higher rsFC with the right amygdala over the right inferior temporal,middle temporal gyrus,middle frontal gyrus,lower rsFC with the right amygdala over the left inferior temporal,superior temporal and the right inferior occipital gyrus,superior occipital gyrus.The IGD group had lower rsFC with the left amygdala over the right rectal gyrus and thalamus.Compared to HC group,the IGD group showed higher dFC variance with the left amygdala over the right middle temporal and the left media frontal gyrus,and lower dFC variance over the right precuneus,inferior parietal lobe,posterior cingulate and the left postcentral gyrus.The IGD group showed higher dFC variance with the right amygdala over right middle frontal gyrus and lower dFC variance with the right amygdala over the right middle temporal,the left media frontal gyrus and paracingulate cortex,inferior parietal lobe.The rsFC between the left amygdala and right rectal gyrus was negatively correlated with Chinese Internet Addiction Scale (CIAS) scores.The dFC variance between the left amygdala over the left postcentral gyrus was positively correlated with CIAS scores.The dFC variance between the left amygdala and the right inferior parietal lobe were negatively correlated with CIAS scores.Conclusion The amygdala participates in the development of IGD.

Forty women with polycystic ovary syndrome( PCOS) were enrolled. Basal plasma and urine cortisol, pituitary hormones, homeostasis model assessment for insulin resistance, and plasma cortisol in 0. 25 mg dexamethasone inhibition test were determined. In over-weight or obese PCOS patients, cortisol levels before and after inhibition test were increased (P<0. 05 or P<0. 01 ). The results suggest that the feed-back regulation of glucocorticoids to hypothalamas-pituitary is impaired and the change in hypothalamic-pituitary-adrenal axis is associated with insulin resistance.

OBJECTIVE: To observe the effect of garlic oil combined with 5-FU induced apoptosis of adenoid cystic carcinoma cell line ACC-M. METHOD: Human salivary in adenoid cystic carcinoma cell line AC-M was cultured, divided into the experimental group (5-FU group, garlic oil group, garlic oil + 5-FU group) and the control group, to observe the growth activity of tumor cells by MTT methods; to analyse the changes of cell cycle and apoptosis rate by flow cytometry. RESULT: MTT experiments showed that 5-FU, garlic oil, garlic oil and 5-FU on ACC-M cells have inhibition in different concentration, with the increase of concentration and action time of the rise; Cell cycle analysis showed significant changes in flow cytometry. With the increase of concentration and the acting time, the G0/G1, phase of the cell ratio increased, S had no significant change, but G2/M phase cells decreased. Apoptosis rate display showed garlic oil combined with 5-FU induced apoptosis of ACC-M cells was significantly stronger than single group. CONCLUSION Garlic oil can effectively induce the apoptosis of adenoid cystic carcinoma cell line ACC-M. The effect of garlic oil combined with 5-FU on ACC-M cells was stronger than the garlic oil, 5-FU used alone.

Objective To investigate the association between the minisatellite polymorphism in the first exon of PLA2G4C gene and schizophrenia, and to reveal the important role of DNA sequence polymorphism in the pathogenesis of schizophrenia.Methods The minisatellite polymorphisms in the first exon of PLA2G4C gene in 91 patients with schizophrenia (case group)and 81 healthy persons (control group)were detected with PCR-sequencing analysis.The chi-square (χ2 )goodness-of-fit test was used to analyze the distribution of the PLA2G4C minisatellite polymorphism in various groups and to explore the association between the minisatellite polymorphism in the first exon of PLA2G4C gene and schizophrenia. Results There were minisatellite polymorphisms in PLA2G4C gene.Three kinds of polymorphisms 1×27 bp,2×27 bp and 3×27 bp were found by sequencing.The distribution of allelic frequencies at PLA2G4C polymorphism showed no statistical significance between case group and control group (P>0.05 ). No statistically significant difference was found in 3-homozygous haplotypes in PLA2G4C gene between case group and control group (P>0.05).At the same time,there was no statistically significant difference between 3-heterozygous haplotypes in PLA2G4C gene between case group and control group (P>0.05).Conclusion The minisatellite polymorphisms in the first exon of PLA2G4C gene are found,but the minisatellite polymorphism in the first exon of PLA2G4C gene may be not associated with the occurrence of schizophrenia.

Objective:To understand the status quo of postoperative exercise adherence in patients with non-small cell lung cancer (NSCLC) and analyze the pathways through which disease perception, exercise self-efficacy, and coping style influence postoperative exercise adherence based on the Revised Common Sense Model (CSM) .Methods:NSCLC patients who underwent surgery in the Department of Thoracic Surgery of the First Affiliated Hospital of Anhui Medical University from March to September 2023 were selected by convenience sampling. Data were collected using a general information questionnaire, the Postoperative Exercise Adherence Questionnaire for Lung Cancer Patients, the Brief Illness Perception Questionnaire (BIPQ), and the Exercise Self-Efficacy Scale for Lung Cancer Patients.Results:A total of 245 questionnaires were distributed, with 241 valid responses collected. The postoperative exercise adherence score among the 241 NSCLC patients was (39.70±9.55). Exercise self-efficacy and coping style partially mediated the relationship between disease perception and exercise adherence, accounting for 81.31% and 13.64% of the total indirect effects, respectively. Exercise self-efficacy and coping style also had a chain mediating effect between disease perception and exercise adherence, accounting for 5.05% of the total indirect effects.Conclusions:The level of exercise adherence in NSCLC patients needs improvement. Negative disease perception not only directly negatively affects exercise adherence but also indirectly affects it through the mediating roles of exercise self-efficacy and coping style. Clinical healthcare providers should focus on guiding patients to develop healthy disease perceptions, increase their confidence in participating in exercise, and encourage the adoption of positive coping styles to enhance exercise adherence levels.

Objective:To study the use of percutaneous transhepatic one-step biliary fistulation based on three-dimensional visualization technology (3D-PTOBF) in the treatment of complex hepatolithiasis.Methods:A retrospective analysis was conducted on 116 patients with complex hepatolithiasis treated in the First Affiliated Hospital of Guangzhou Medical University from January 2016 to December 2019. There were 56 patients in the 3D-PTOBF group (treated by 3D-PTOBF), and 60 patients in the traditional PTOBF group (received traditional PTOBF approach). The stone clearance rate, postoperative complication rate, intraoperative blood loss, hospitalization time, number of cholangioscopic treatment procedures and stone recurrence rate were compared between the two groups.Results:When compared with the traditional PTOBF group, the 3D-PTOBF group had significantly less procedures (1.43±0.71 vs. 2.07±1.22, P<0.05), and shorter hospital stay (4.6±2.3 d vs. 6.1±2.9 d, P<0.05). There were no significant differences in the immediate stone clearance, final stone clearance, postoperative complications and stone recurrence rates between the two groups (all P>0.05). Conclusion:3D-PTOBF was safe and feasible to treat complex hepatolithiasis. When compared with PTOBF, it had the advantages of shorter operation time and decreased hospital stay.

OBJECTIVETo assess the association of a disintegrin and metallo-proteinase with thrombospondin type 1 motifs (ADAMTS-1) gene polymorphism and ischemic stroke caused by large artery atherosclerosis (LAA).

METHODSIn total 767 patients and 506 controls were recruited. Single nucleotide polymorphisms (SNPs) rs416905 (T/C) and rs402007 (G/C) of the ADAMTS-1 gene were genotyped by polymerase chain reaction and DNA sequencing.

RESULTSFrequencies of the rs402007 GC+CC genotype and the C allele were significantly different between the two groups (68.84% vs. 60.67%, χ2=9.012, P=0.003, OR=1.432; 45.24% vs. 38.54%, χ2=11.208, P=0.001, OR=1.318). Binary logistic regression has confirmed that the above difference was significant (P=0.001, OR=1.521, 95%CI: 1.183-1.955). The frequencies of TC+CC and GC+CC genotypes were similar between the two groups, and so was it with the C allele. The two SNPs had been in complete linkage disequilibrium (D'=1.0, r2=1.0).

CONCLUSIONThe rs416905 and rs402007 polymorphisms of the ADAMTS-1 gene may be associated with ischemic stroke caused by LAA. The C allele of the rs402007 locus may be a susceptibility factor for this subtype of stroke.
