Objective:To investigate the correlation between the clinical features and endoscopic ultrasound-guided portal pressure gradient (EUS-PPG) in patients with cirrhosis.Methods:A total of 148 patients with cirrhosis and portal hypertension who underwent EUS-PPG measurement at the Third Xiangya Hospital of Central South University from March 15, 2022 to June 20, 2023 were selected. The clinical data of patients collected before EUS-PPG measurement were analyzed. Variations in the EUS-PPG across different clinical data subgroups were analyzed. Multivariate linear regression analysis was used to explore the independent factors influencing EUS-PPG.Results:The EUS-PPG was significantly elevated in patients exhibiting red signs (16.62±5.33 mmHg VS 13.44±5.34 mmHg, t=3.616, P<0.001), gastroesophageal varices (15.78±5.30 mmHg VS 9.70±4.77 mmHg, t=4.247, P<0.001), hepatic encephalopathy (20.83±7.52 mmHg VS 14.92±5.35 mmHg, t=2.606, P=0.010), thrombocytopenia (15.66±5.39 mmHg VS 13.29±5.83 mmHg, t=2.136, P=0.034), hypoproteinemia (16.13±5.86 mmHg VS 14.12±5.03 mmHg, t=2.230, P=0.027), and an increased international normalized ratio (16.25±6.00 mmHg VS 14.40±5.11 mmHg, t=2.022, P=0.045). Conversely, the EUS-PPG was significantly reduced in patients with a history of splenectomy and devascularization (13.17±5.88 mmHg VS 15.73±5.34 mmHg, t=-2.379, P=0.019). The EUS-PPG in patients with varying degrees of ascites (no VS slight VS moderate or severe: 13.40±5.48 mmHg VS 15.90±5.49 mmHg VS 16.69±5.17 mmHg, F=5.188, P=0.007) and different Child-Pugh classifications (A VS B VS C: 14.07±5.05 mmHg VS 15.69±5.74 mmHg VS 17.64±5.99 mmHg, F=3.066, P=0.049) increased gradually. Multivariable linear regression analysis showed that red signs ( β=2.44, t=2.732, P=0.007), gastroesophageal varices ( β=4.45, t=2.990, P=0.003), ascites ( β=1.75, t=2.368, P=0.019), and hepatic encephalopathy ( β=5.82, t=2.644, P=0.009) were independent factors for the elevated EUS-PPG. Conclusion:There is a significant correlation between EUS-PPG and the clinical features related to the severity of cirrhotic portal hypertension, which indicates the feasibility of EUS-PPG in evaluating cirrhotic portal hypertension.

Objective:To investigate the impact of short-term variability in fasting blood glucose (FPG) on the recent major cardiovascular adverse events (MACE) in patients with ST segment elevation myocardial infarction (STEMI) with different levels of glycated hemoglobin (HbA 1c) . Methods:Retrospective analysis was made on the patients with type 2 diabetes mellitus who underwent emergency percutaneous coronary intervention (PCI) due to STEMI from January 2016 to March 2020 in Shenzhen Hospital, Fuwai Hospital, Chinese Academy of Medical Sciences. The patients were divided into HbA 1c compliant group (<6.5%) and non-compliant group (≥6.5%). The blood glucose variability indexes defined included FPG variability score (FPG-VS), variability index independent of FPG mean (VIM) and mean fast plasma glucose (FPG-M). The logistic regression model was used to evaluate the relationship between different HbA 1c levels, blood glucose variability risk indicators, and MACE. Results:A total of 612 patients were ultimately included in the analysis. The blood glucose variability indicators (FPG-VS, VIM) of the HbA 1c non-compliant group (302 cases) were higher than those of the compliant group (310 cases): [FPG-VS: (0.7±0.3) vs (0.4±0.4), P<0.001, VIM: (0.4±0.2) vs (0.3±0.2), P<0.001], while there was no statistically significant difference in FPG-M between the two groups [(7.9±3.2) vs (8.0±3.9), P=0.221]. In the HbA 1c non-compliant group, the correlation between FPG-VS, VIM, and FPG-M and the risk of MACE within 30 days was 0.89(95% CI: 0.69-1.15), 1.21(95% CI: 0.65-2.25), and 1.06(95% CI: 0.97-1.16), respectively (all P>0.05). In the HbA 1c compliant group, FPG-VS was associated with an increase in MACE risk within 30 days ( P=0.04): for each increase in FPG variation ≥1 mmol/L, after multiple factor adjustment, the risk of MACE increased by 8% within 30 days ( OR=1.08, 95% CI: 0.71-1.65); Compared with FPG-VS<20%, FPG-VS≥80% increased the risk of MACE within 30 days by 33% ( OR=1.33, 95% CI: 0.21-8.25, P<0.01), while the correlation between VIM and FPG-M and the risk of MACE within 30 days was 1.65(95% CI: 0.96-2.83) and 1.15(95% CI: 0.98-1.35), respectively (all P>0.05). Conclusions:High FPG-VS is associated with the recent MACE risk in STEMI patients who do not meet HbA 1c standards. After reaching HbA 1c standards, FPG-VS remains an independent MACE risk factor.

Objective To investigate the protection effect of cyclosporine A on spatial memory following chronic cerebral hypoperfusion in rats and its possible mechanism.Me,ods Sixty SD rats were randomly divided into sham operation,vehicle,low-dose cyclosporine A,medium-dose cyclosporine A,and high-dose cyclosporine A groups.A chronic cerebral hypoperfusion model was prepared by permanent bilateral ligation of bilateral common carotid arteries.From 46 days after modeling,olive oil 1 ml/d was used for intragastric administration in the sham-operation group and the vehicle group.Cyclosporine A 3 mg/kg,6 mg/kg,and 12 mg/kg were administrated intragastrically in the low-dose,medium-dose and high-dose cyclosporine A groups,respectively,once a day for 14 days.The spatial memory was assessed using Morris water maze test.Reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the expression of NADPH oxidase 4 (NOX4) mRNA in the cerebral cortex.Immunohistochemical staining and Western blot were used to detect the expression of NOX4 protein in the cerebral cortex.Results The Morris water maze test showed that the escape latencies in all cyclosporine A groups were significantly shorter than the vehicle group (all P ＜0.05).Immunohistochemical staining showed that the percentages of the NOX4-positive cells in the sham-operation,vehicle,low-dose,medium-dose,and high-dose cyclosporine A groups were4.43％ ±0.37％,37.44％ ±4.76％,18.05％ ±2.91％,12.51％ ±3.4％,and 11.06％ ±1.74％,respectively (F =262.021,P ＜ 0.001),the vehicle group was significantly higher than the sham-operation group (P ＜ 0.01),and all cyclosporine A groups were significantly less than the vehicle group (all P ＜ 0.01).RT-PCR showed that the expression levels of NOX4 mRNA in cerebral cortex in the sham-operation,vehicle,low-dose,medium-dose,and high-dose cyclosporine A groups were 0.36 ± 0.03,1.04 ± 0.04,0.58 ± 0.02,0.49 ± 0.01,and 0.40 ± 0.02,respectively (F =1 324.941,P ＜ 0.001),all cyclosporine A groups were significantly lower than the vehicle group (all P ＜ 0.01).Western blot showed that the expression levels of NOX4 protein in cerebral cortex in the sham-operation,vehicle,low-dose,medium-dose,and high-dose cyclosporine A groups were 0.02 ± 0.01,0.27 ± 0.04,0.09 ± 0.02,0.06 ± 0.02,and 0.06 ± 0.01,respectively (F =222.692,P ＜ 0.001),all cyclosporine A groups was significantly lower than the vehicle group (all P＜0.01).Conclusion Cyclosporine A may improve spatial memory following chronic cerebral hypoperfusion in rats by down-regulation of NOX4.

Background and purpose:For stageⅠ non-small cell lung cancer (NSCLC), video-assisted thoracic segmentectomy is given much attention to by thoracic surgeon because of the less tissue damages. However, video-assisted thoracic lobectomy is still considered as the standard treatment in the world. Therefore, this study was to evaluate the clinical effect after video-assisted thoracic segmentectomy and lobectomy in patients with stageⅠ NSCLC in order to provide reference for clinical application.Methods:The comparative studies on video-assisted thoracic segmentectomy and lobectomy treating stage I NSCLC were retrieved from PubMed, Web of Science, EMBASE, the Cochrane Library, CNKI, CBM, VIP, and Wanfang Data. All data were acquired until July 2015. Literature screening according to data extraction and quality assessment was completed by two reviewers independently. Meta-analysis was conducted by RevMan 5.3 software which was offered by Cochrane network.Results:A total of 11 articles involving 1 677 patients were ifnally included. The results of meta-analysis indicated that: for stageⅠ NSCLC, compared with video-assisted thoracic lobectomy, the effect of video-assisted thoracic segmentectomy was alike in total mortality (OR=0.77, 95%CI: 0.48 to 1.21,P=0.25), 5-year mortality (OR=0.77, 95%CI: 0.52 to 1.14,P=0.19) and systemic complications (OR=0.76, 95%CI: 0.53 to 1.09,P=0.13), but could reduce blood loss [difference in means (MD)=-41.16, 95%CI: -59.46 to -22.86,P<0.000 1], chest tube duration (MD=-0.29, 95%CI: -0.49 to -0.09,P=0.005) and the length of hospital stay (MD=-0.74, 95%CI: -1.44 to -0.05,P=0.04).Conclusion:Compared with video-assisted thoracic lobectomy, video-assisted thoracic segmentectomy can signiifcantly reduce blood loss, chest tube duration and length of hospital stay. However, the two kinds of operation methods achieved the same effects on the total mortality, 5-year mortality and systemic complications. Thoracoscopic segmentectomy may be an alternative to thoracic lobectomy.

OBJECTIVEBenign epilepsy with centro-temporal spikes (BECTs) is a common idiopathic partial epileptic syndrome in childhood, which often affect the pre-school and school-age children and a considerable proportion have comorbidity including lower academic achievement and cognitive impairment. Few studies involved the psychocognitive assessment in such a drug-treatable epileptic syndrome especially in the newly diagnosed and medications-naive group. This study aimed to investigate the cognitive characteristics of children with newly onset BECTs before treatment.

METHODForty-one outpatients with newly diagnosed BECTs who visited the Clinic during the periods from October 2012 to May 2014 before the medications against epilepsy and 41 healthy controls recruited from regular school in Beijing during the period from July 2013 to March 2014, who matched in age and gender underwent battery testing by computerized cognitive testing in epilepsy (CCTE). The BECTs group included 41 children, 20 boys and 21 girls, mean age (8.2 ± 1.7) years, the age of onset of epilepsy 4.5-11.5 years (the age of onset <8 years in 25 cases, ≥ 8 years in 16 cases). The cognitive characteristics and associated factors were analyzed. The primary data including correct answer numbers and reaction times were analyzed by independent sample t-test between the two groups of children with BECTs and healthy controls based on SPSS 18.0 statistical software.

RESULTRaw data of 9 tasks' scores collected from BECTs and healthy control children were continuous variables in accordance with normal distribution. BECTs children performed significantly worse than controls in choice reaction time ((618+158) vs. (524+254) ms), three-dimensional mental rotation (11 ± 10 vs. 18 ± 12) and visual tracing (10 ± 6 vs.15 ± 6), t=2.01, 3.03 and 3.47, P<0.05, <0.01 and <0.001, respectively.While other 6 tasks showed no significant difference between the two groups (P>0.05 for all comparisons). BECTs boys performed significantly worse than girls on simple substraction tasks compared with standard nine score ((4.7 ± 1.5) vs. (5.6 ± 1.2), t=-2.24, P<0.05). Other 8 tasks showed no significant difference between boys and girls (P>0.05 for all comparisons). Other 9 tasks showed no significant differences between the two groups of BECTs children whose age of onset was before 8 years and those who started seizure ≥ 8 years (P all >0.05). The standard nine scores of simple substraction from the three BECTs groups of dominance sides of spikes and waves during NREM showed significant difference (P<0.05). BECTs children with bilateral discharges performed significantly worse than the other two groups dominantly right or left discharges (4.7 ± 1.2 vs. 6.0 ± 1.2 vs. 4.9 ± 1.4, P all <0.05). There was no significant difference between the two groups with right and left side dominance discharges (P>0.05). Other 8 tasks showed no significant differences among the three groups (P>0.05 for all comparisons).

CONCLUSIONAlthough EEG discharges index below 50% during NREM period, while newly diagnosed BECTs children before treatment with medications against epilepsy performed poorer on tasks of choice reaction time, three-dimensional mental rotation, and visual tracing. The two factors of male and bilateral discharges during NREM period correlate with dysfunction of simple subtraction, the mechanism needs further study and the cognitive function of epilepsy children should be evaluated and followed up, in order to provide psychologic baseline data for persistent cognitive disturbance.

Objective To know the effects of living with the elderly on nursing students' willingness engaging in aged nursing and attitude towards the elderly so as to provide references for nurturing professionals for caring for the aged.Methods 231 nursing students were surveyed.The questionnaire included four parts,general information,life experience with the elderly,willingness engaging in aged nursing,attitude towards the elderly and cognition of aging.Results 45.9 percent of the nursing students were willing to engage in aged nursing.Living with elderly and relationship with the elderly affected their willingness.Conclusions Creating more opportunities for nursing students in touch with the elderly can help nursing students to have a good impression of the elderly and stimulate them to choose aged nursing.

OBJECTIVETo evaluate the long-term clinical outcomes of fractional flow reserve (FFR)-guided versus intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for intermediate coronary lesions.

METHODSA total of 226 patients with 293 intermediate coronary artery lesions (stenosis of 40%-70%) confirmed by coronary angiography were randomized into 3 groups to undergo PCI for a minimal lumen cross sectional area (MLA)<4 mm(2) (IVUS group, 98 lesions) or for a FFR<0.80 (FFR group, 101 lesions), or to receive standard medical treatment (medication group, 94 lesions). The primary outcome was major adverse cardiac events including death, myocardial infarction, and ischemia-driven target vessel revascularization at 1 year after the index procedure.

RESULTSThe baseline percent diameter stenosis and lesion length were similar between the 3 groups, but more patients in IVUS group than in FFR group received PCI (P<0.001). No significant difference was found in the incidence of major adverse cardiac events between the 3 groups (P=0.182).

CONCLUSIONBoth FFR- and IVUS-guided PCI strategy for intermediate coronary artery disease are associated with favorable outcomes, but IVUS-guided PCI based on the single index of MLA can increase the rate of revascularization therapy.
