Objectives:To explore the influencing factors of daily living abilities in patients with traumatic spinal cord injury.Methods:A cross-sectional study was conducted on 148 patients with traumatic spinal cord injury admitted to our hospital from January 2019 to January 2023.Factors that may affect the daily living abilities of patients were collected,including gender,age,marital status,course of injury,cause of in-jury,level of injury,American Spinal Injury Association(ASIA)impairment scale(AIS),surgical situation and urination pattern.The spinal cord independence measure Ⅲ(SCIM-Ⅲ)was used to evaluate the daily living abilities in patients with traumatic spinal cord injury.The relationship between the influencing factors and daily living abilities was analyzed by single factor analysis,and multiple linear regression was applied to ana-lyze the impact of the influencing factors on daily living abilities.Results:Univariate analysis showed that the level of injury,AIS and,the urination pattern had significant effects on daily living abilities(P＜0.05),while gender,age,marital status,course of injury,cause of injury,surgical situation had no significant effects on daily living abilities.With regard to the level of injury,patients with sacral spinal cord injury had the best daily living abilities,and patients with cervical spinal cord injury were the worst in daily living abilities.Regarding AIS,patients of level A were the worst in daily living abilities,and patients of level E were the best.In terms of urination pattern,patients who could spontaneous voiding were the best in daily living abil-ities,while those with indwelling catheter/bag had the worst daily living abilities.There were statistically significant differences in self-care,respiratory and sphincter management,movement and total scores between patients with different injury levels,urination patterns and AIS(P＜0.01).Multiple linear regression showed that injury level,urination pattern and AIS were the main factors affecting the daily living abilities.Conclusions:The level of injury,AIS,and the urination pattern are the main factors affecting the daily living abilities of patients with traumatic spinal cord injury,and patients with injury of cervical cord,AIS level A,and indwelling catheter/bag have poor daily living abilities.

Objective To investigate the value of eclampsia risk prediction combined with umbilical artery peak systolic velocity/end diastolic velocity(S/D)ratio in predicting pregnancy outcomes in patients with gestational diabetes mellitus.Methods Select 60 cases of gestational diabetes mellitus(GDM)patients admitted to ourhospital's obstetrics outpatient department from January 2021 to January 2023 as the gestational diabetes group.At the same time,select 30healthy pregnant women who received regular prenatal check-ups in ourhospital's obstetrics outpatient department as the control group.Determination of placental growth factor(PIGF)in serum by magnetic particle chemiluminescence.The ratio of S/D ratio to was measured by ultrasound.At the same time,they were divided into good pregnancy outcome group and bad pregnancy outcome group according to whether combined with adverse pregnancy outcome,and the PIGF and S/D ratio were compared.We performed a predictive analysis using receiver operating characteristic(ROC)curve analysis to assess the predictive value of PIGF combined with the S/D ratio for the pregnancy outcomes in GDM patients.Results Compared with the control group,patients in the gestational diabetes mellitus(GDM)group showed a decrease in PIGF levels and an increase in the S/D ratio of systolic to diastolic velocities(S/D ratio)(P＜0.05).The incidence of adverse pregnancy outcomes was 46.67% in the GDM group,significantlyhigher than the 20.00% in the control group(P＜0.05).Compared with the group with favorable pregnancy outcomes,the GDM group with adverse pregnancy outcomeshad lower PIGF levels andhigher S/D ratio(P＜0.05).ROC curve analysis showed that both PIGF and S/D ratio were sensitive markers for predicting adverse pregnancy outcomes in GDM patients,with S/D ratio having ahigher diagnostic efficacy than PIGF alone,but the combination of both markers yielded greater accuracy.Conclusion The decrease of PIGF level and the increase of S/D ratio in patients with gestational diabetes mellitus are correlated with adverse pregnancy outcomes,and PIGF combined with S/D ratiohas thehighest diagnostic efficacy in patients with adverse pregnancy outcomes.

AIM:To explore the therapeutic effect of teprenone(geranylgeranylacetone,GGA)on lipopolysac-charide(LPS)-induced cardiac dysfunction and its mechanism.METHODS:(1)Eight-week-old male C57BL/6 wild-type mice and carboxyl terminus of heat shock protein 70(HSP70)-interacting protein(CHIP)gene knockout mice were randomly divided into control group,LPS group,LPS+GGA group and GGA group,with 8 mice in each group.The model was established by intraperitoneal injection of LPS(25 mg/kg),and 1 h after LPS stimulation,mice were given intraperito-neal injection of GGA(100 mg/kg).The technique of high-resolution ultrasonography system was used to evaluate the car-diac function of mice.The serum of mice from each group were collected to detect the levels of creatine kinase-MB(CK-MB)and lactate dehydrogenase(LDH).HE staining was performed to observe histological changes of cardiac tissues.ELISA was used to detect the levels of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in cardiac tissues.West-ern blot was used to detect the protein levels of HSP70,CHIP,karyopherin-α 2(KPNA2),myeloperoxidase(MPO),vas-cular cell adhesion molecule(VCAM),intercellular cell adhesion molecule(ICAM),and nuclear factor-κB(NF-κB)in cardiac tissues.(2)In vitro cell inflammation model was established using mouse myocardial cells HL-1 stimulated with LPS.ELISA was used to detect the levels of TNF-α and IL-6 in cell supernatants.Western blot was used to detect the pro-tein expression levels of HSP70,CHIP,and KPNA2 in myocardial cells.Immunofluorescence staining was performed to observe the content of nuclear NF-κB.RESULTS:(1)GGA effectively improved cardiac function of LPS-stimulated mice,significantly increased ejection fraction and left ventricular fractional shortening(P<0.01),reduced serum levels of CK-MB and LDH(P<0.01),and alleviated myocardial injury.(2)GGA significantly reduced the release of TNF-α and IL-6 caused by LPS(P<0.01),as well as nuclear translocation of NF-κB,decreased the levels of KPNA2,MPO,VCAM and ICAM in cardiac tissues,and increased the levels of HSP70 in cardiac tissues and cells(P<0.01).(3)In CHIP knockout myocardial cells and mice,GGA failed to inhibit LPS-induced inflammatory response and lost its effect on im-proving cardiac function.CONCLUSION:The protective effect of GGA against LPS-caused cardiac dysfunction of mice is related to increasing expression of HSP70 and promoting CHIP activation,which inhibits the translocation of NF-κB into nucleus and suppresses inflammatory factor release.CHIP knockout abolishes the effects of GGA on reducing LPS-induced inflammatory response and myocardial injury.

Objective:To quantitatively evaluate left ventricular myocardial work in patients with type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) by pressure strain loop (PSL) technique.Methods:A total of 103 T2DM patients diagnosed at the Heping Hospital Affiliated to Changzhi Medical College from April 2022 to May 2023 were selected. They were divided into three groups based on their fatty liver ultrasound findings: group A (34 cases without NAFLD), group B (37 cases with mild NAFLD), and group C (32 cases with moderate to severe NAFLD). All patients underwent routine echocardiography, which measured the end diastolic left ventricular diameter (LVIDd), end systolic left ventricular diameter (LVIDs), end diastolic interventricular septum (IVSTd), left ventricular posterior wall thickness (LVPWTd), and end systolic left atrial diameter (LAD). The biplane Simpson method was used to measure left ventricular ejection fraction (LVEF), end diastolic left ventricular volume (LVEDV), and end systolic left ventricular volume (LVESV). PSL technology was applied to analyze the overall longitudinal strain (GLS), global work index (GWI), global effective work (GCW), global ineffective work (GWW), and overall work efficiency (GWE) of the left ventricular myocardium. We compared the conventional echocardiography parameters and myocardial work parameters among three groups, and analyzed the correlation between myocardial work parameters and GLS and glycosylated hemoglobin (HbA 1c). Results:The differences in body mass index (BMI), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) between group B and group A were statistically significant (all P<0.05); There was a statistically significant difference in BMI, HbA 1c, and low density lipoprotein cholesterol (LDL-C) between group C and group B (all P<0.001); The differences in BMI, HbA 1c, ALT, AST, triglyceride (TC), high density lipoprotein cholesterol (HDL-C), and LDL-C between group C and group A were statistically significant (all P<0.05). The GWI and GCW in group B were lower than those in group A (all P<0.05), while the absolute GLS, GCW, GWI, and GWE in group C were lower than those in group A, and GWW was higher than those in group A (all P<0.05); The absolute values of GLS, GCW, GWI, and GWE in group C were lower than those in group B ( P<0.05). The correlation analysis results showed that GLS and HbA 1c were negatively correlated with GCW and GWI ( r=-0.571, -0.533, -0.273, -0.223, P<0.05). Conclusions:PSL technology can quantitatively evaluate left ventricular myocardial work in patients with T2DM combined with NAFLD, and can detect early impairment of left ventricular systolic function in patients. It has clinical reference value in evaluating overall and local cardiac function.
