[Objective]To forecast the sponge mechanism mediated by LOC389023 in patients with intractable temporal lobe epilepsy(TLE),through investigating the expression of microRNA interacted with dipeptidyl peptidase 10(DPP10)and LOC389023.[Methods]The expression of DPP10 and Kv4.3 were detected in 15 temporal neocortex from patients with brain trauma (control group)and in 26 temporal neocortex from patients with intractable TLE(epilepsy group)by western blot(WB)and immunohisto?chemical(IHC)staining. The location of DPP10 and voltage dependent potassium channel 4.3(Kv4.3)was detected by immunofluo?rescent(IF)staining. The interaction between DPP10 and Kv4.3 was testified by co-immunoprecipitation(Co-IP). The expression of microRNA obtained by softwares(miRanda,Pita,TargetScan and miRDB)was detected by qPCR.[Results]IHC and WB showed an increased expression of DPP10(P<0.05)and a decreased expression of Kv4.3(P<0.05)in the epilepsy group. IF showed that the DPP10 and the Kv4.3 co-expressed in the membrane and the cytoplasm of neurons. Co-IP showed obvious interaction between the DPP10 and the Kv4.3.Five microRNA(miR-32-5p,miR-140-5p,miR-367-3p,miR-25-3p,miR-4325)were obtained by soft?wares. No significant differences in the expression of miR-32-5p and miR-4325 were found between epilepsy group and control group by qPCR(P>0.05). But decreased expression of LOC389023 and miR-140-5p and increased expression of miR-25-3p and miR-367-3p were found in epilepsygroup compared to control group (P < 0.05).[Conclusion]miR-25-3p and miR-367-3p may be regulated by LOC389023 through the sponge mechanism followed by altered expression of DPP10 in intractable temporal lobe epilepsy.

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 investigate the clinical value of left ventricular shape index (SI) and eccentricity index (EI) in evaluating left ventricular remodeling.Methods:A retrospective analysis was performed on 324 patients (264 males, 60 females, age (62.5±11.8) years) diagnosed with myocardial infarction (MI) and 113 healthy controls (HC; 47 males, 66 females, age (57.8±10.7) years) who received gated myocardial perfusion imaging (GMPI) in First Hospital of Shanxi Medical University from January 2016 to September 2020. SI (end-diastolic SI (EDSI), end-systolic SI (ESSI)), EI and left ventricular function parameters (end-diastolic volume (EDV), end-systolic volume (ESV), left ventricular ejection fraction (LVEF), summed motion score (SMS), summed thickening score (STS), peak ejection rate (PER) and peak filling rate (PFR)) were obtained by quantitative gated SPECT (QGS) software. Propensity score (PS) inverse probability of treatment weighting (IPTW) was used to balance the intergroup covariates. The differences and correlations of EDSI, ESSI, EI and left ventricular function parameters between patients in MI group and HC group were analyzed. ROC curve analysis was used to evaluate the values of EDV, EDSI, ESSI and EI alone and in combination in the assessment of left ventricular systolic function impairment. Data were analyzed by independent-sample t test, Pearson correlation and Spearman rank correlation analyses, and Delong test. Results:After IPTW, EDSI and ESSI in MI group ( n=319) were higher than those in HC group ( n=133; EDSI: 0.66±0.09 vs 0.60±0.06; ESSI: 0.59±0.11 vs 0.47±0.07; t values: 8.05, 14.67, both P<0.001), and EI was lower than that in HC group (0.81±0.06 vs 0.85±0.03; t=-8.93, P<0.001). In both groups, there were significant correlations between EDSI and ESSI ( r values: 0.928, 0.873), between EDSI, ESSI and EI ( r values: from -0.831 to -0.641), between EDSI, ESSI and LVEF ( r values: from -0.627 to -0.201), between ESSI and EDV, ESV and SMS ( rs values: 0.336-0.584), between ESSI and -PER, PFR ( rs values: from -0.406 to -0.402, r values: from -0.352 to -0.325) (all P<0.01). ROC curve analysis showed that EDV (AUC: 0.895) and ESSI (AUC: 0.839) had the highest efficacy in evaluating left ventricular systolic function impairment in MI group and HC group, respectively. EDV-EDSI-ESSI-(1-EI) had higher efficacy in the assessment of impaired left ventricular systolic function in MI group (AUC: 0.956), which was higher than that of EDV or EDV-EDSI or EDV-ESSI or EDV-(1-EI) ( z values: from -2.64 to -2.18, P values: 0.008-0.029); EDV-EDSI-ESSI-(1-EI) also had high efficacy in HC group (AUC: 0.911), which was higher than that of EDV or EDV-EDSI or EDV-(1-EI) ( z values: from -2.60 to -2.43, P values: 0.009-0.015). Conclusions:In MI patients, the increase of SI and the decrease of EI indicate the increase of left ventricular sphericity and the aggravation of left ventricular remodeling. SI and EI have certain clinical application values in evaluating left ventricular morphology, predicting left ventricular remodeling and left ventricular systolic function impairment.

Objective:To compare the incidence of coronary microvascular disease (CMVD) between patients with non-obstructive and obstructive coronary arteries.Methods:We retrospectively analyzed 97 patients with angina pectoris, who underwent the absolute quantitative PET examination of myocardial perfusion and coronary anatomy examination within 90 days. All patients were divided into two groups: non-obstructive group (72 cases, no stenosis ≥50% in all three coronary arteries) and obstructive group (25 cases, at least one coronary stenosis ≥50%; and at least one coronary stenosis<50%). Quantitative parameters derived from PET including rest myocardial blood flow (RMBF), stress myocardial blood flow (SMBF), coronary flow reserve (CFR) and cardiovascular risk factors were compared between the two groups. CMVD was defined as CFR<2.90 and SMBF <2.17 ml·min -1·g -1. Results:Incidence of CMVD was significant higher in the non-obstructive coronary arteries of the obstructive group than in the non-obstructive coronary arteries of non-obstructive group (47.1% (16/34) vs. 25.5% (55/216), χ 2=6.738, P=0.009) while incidence of CMVD was similar between non-obstructive and obstructive patients ((44% (11/25) vs. 33.3% (24/72), χ 2=0.915, P=0.339). RMBF ((0.83±0.14) ml·min -1·g -1 vs. (0.82±0.17) ml·min -1·g -1), SMBF ((2.13±0.60) ml·min -1·g -1 vs. (1.91±0.50) ml·min -1·g -1) and CFR (2.59±0.66 vs. 2.36±0.47) were similar between the two groups (all P>0.05). Conclusions:CMVD can occur in non-obstructive coronary arteries in both patients with non-occlusive coronary arteries and patients with obstructive coronary arteries. Prevalence of CMVD is significantly higher in patients with obstructive coronary arteries than in patients with non-obstructive coronary arteries. The CMVD severity is similar between the two groups.
