Objective:To explore the application value of non-invasive myocardial work imaging in evaluating the cardiac function of ST-segment elevation myocardial infarction (STEMI) patients with left ventricular remodeling (LVR) after percutaneous coronary intervention (PCI).Methods:One hundred and twenty-six patients with STEMI undergoing PCI in General Hospital of Ningxia Medical University from December 2021 to September 2022 were prospectively collected and divided into left ventricular remodeling group (LVR group, 34 cases) and non left ventricular remodeling group (NLVR group, 92 cases) according to whether there was left ventricular remodeling 3 months after surgery. General data were collected. Routine echocardiography and noninvasive myocardial work imaging were performed before, 1 week, 1 month, and 3 months after surgery, the differences in the above parameters between the two groups were compared. Pearson correlation analysis was used to analyze the correlation between the indicators.Logistic regression analysis was used to determine the independent risk factors of left ventricular remodeling after STEMI, and a predictive model was obtained. The diagnostic value of the model was judged by ROC curve.Results:①General information comparison: There were statistically significant differences between the two groups in BMI, systolic blood pressure, diastolic blood pressure, average number of stents implanted, and history of hyperlipidemia (all P<0.05), but there was no significant difference in other data (all P>0.05). There was no statistically significant difference in two-dimensional transthoracic echocardiography (2D-TTE) parameters and non-invasive myocardial work (MW) parameters between the two groups before and 1 week after operation (both P>0.05). ②2D-TTE parameter comparison: LVESV and LVEDV at 3 months after PCI in the LVR group were significantly higher than those in the NLVR group, and LVEF and E/A were significantly lower than those in the NLVR group (all P<0.05); There were no significant differences in other indexes between the two groups by conventional echocardiography at 3 months after PCI(all P>0.05). ③Comparisons of noninvasive myocardial work parameters: GLS, GWE, GWI, GCW at 1 month and 3 months after PCI in the LVR group were significantly lower than those in the NLVR group, and GWW were significantly higher than those in the NLVR group ( P<0.001). ④Correlation analysis: GLS, GWE, GCW, GWI and LVEDV were negatively correlated at 1 month after operation ( r=-0.42, -0.38, -0.50, -0.53, all P<0.001), GWW was positively correlated with LVEDV ( r=0.45, P<0.001). ⑤Logistic regression analysis: GLS<17%, GCW<1 900 mmHg%, GWW>105 mmHg%, and GWE<90 mmHg% at 1 month after PCI were independent predictors for LVR in STEMI patients after PCI (all P<0.05). The predictive model was Logit (P)=0.692GLS+ 0.804GCW+ 0.972GWW+ 0.880GWE. The AUC of this model was 0.886, 95% CI=0.845-0.926, which was significantly higher than single index, the sensitivity was 0.86, and the specificity was 0.79. Conclusions:GLS, GWE, GWI, GCW are positively correlated with LVR, while GWW is negatively correlated with left ventricular remodeling. Noninvasive myocardial work parameters are independent risk factors for left ventricular remodeling in patients with STEMI after PCI surgery. This technique can be used to evaluate LVR and has great clinical application value.

Value of urinary C-terminal agrin fragment in monitoring the progression of early kidney injury in type 2 diabetic patients / 中华检验医学杂志

Objective:This study aimed to explore the feasibility and clinical value of monitoring the progression of early kidney injury in type 2 diabetic patients by assessment of the urinary C-terminal agrin fragment (uCAF) with enzymatic chemiluminescence immunoassay.Methods:A total of 251 patients with type 2 diabetes, who attended the Second Affiliated Hospital of Wenzhou Medical University from October 2018 to March 2020, were included in this retrospective analysis. One hundred and fifty-six participants undergoing health check-up at the Second Affiliated Hospital of Zhejiang University School of Medicine in February 2021 served as controls. Basic clinical information, glycosylated hemoglobin type A 1c and serum creatinine values were recorded, and urine specimens were collected for urinary creatinine, urinary α 1 microglobulin(uα 1M), urinary immunoglobulin G (uIgG), urinary albumin, urinary N-Acetyl-B-D-glycosaminidase (uNAG) and uCAF measurements. Based on the estimated glomerular filtration rate (eGFR), 251 patients were classified into G1~G5 stage groups with 116, 22, 28, 55 and 30 patients in each group. One hundred and sixty-six patients with early diabetic kidney disease (stage G1-G3) were divided into subgroups A1 (79), A2 (48) and A3 (39) according to the urinary albumin/creatinine ratio (UACR), the uα1M levels were divided into uα1M subgroup 1 (83 cases), uα1M subgroup 2 (42 cases), and uα1M subgroup 3 (41 cases), and uIgG subgroup 1 (83 cases), uIgG subgroup 2 (42 cases), and uIgG subgroup 3 (41 cases) according to uIgG levels. The Spearman method was used to analyze the correlation between uCAF levels and eGFR, UACR, uα1M and uIgG levels. Results:(1) The linear range of the uCAF detected by enzymatic chemiluminescence immunoassay was 3.97-2 000.00 ng/ml, with a detection limit of 2.28 ng/ml, intra-batch coefficients of variation of 1.15% and 1.57%, inter-batch coefficients of variation of 1.63% and 5.78%, and a biological reference interval of <95.35 μg/g Cr. (2) The uCAF level and positive rate (UACR≥30 mg/g) increased with the decrease of eGFR from G1-G3, uCAF level was negatively correlated with eGFR value ( r=-0.543, P<0.000 1), and the positive rate increased from 24.14% (28/116) to 85.71% (24/28) from G1-G3. The uCAF level and positivity rate decreased with the decrease of eGFR from G4 to G5. uCAF level was positively correlated with eGFR value ( r=0.495, P<0.001), and the positivity rate decreased from 30.91% (17/55) to 23.33% (7/30) from G4 to G5. (3) In patients with early diabetic kidney disease, uCAF levels and positivity rates increased gradually with the increase of UACR. uCAF levels were positively correlated with UACR values ( r=0.602, P<0.001), and the uCAF positivity rate reached 21.52% (17/79) in the A1 subgroup. (4) uCAF level was positively correlated with uα1M and uIgG levels in patients with early diabetic kidney disease ( r=0.757, 0.596, both P<0.001). Conclusion:Analytical performance of enzyme chemiluminescence immunoassay for the detection of CAF is satisfactory and could be used a biomarker for monitoring damage and progression of early diabetic kidney disease in patients with type 2 diabetes.

Research of epigenetics related to extracellular matrix remodeling in bronchopulmonary dysplasia / 国际儿科学杂志

Bronchopulmonary dysplasia(BPD)is a chronic pulmonary disease related to preterm neonatal.The pathogenesis of BPD hasn′t been clear now.But we have already known extracellular matrix remodeling has played an important role in alveoli dysplasia.We have found epigenetics has participated in extracellular matrix remodeling.There is a strict balance between the composition and decomposition of the ECM under the physiology state.However the ECM will reconstruct when its component change, which would influence the normal physiology process and lead to the disease.The review describes DNA methylation′s and microRNAs′ functions in extracellular matrix remodeling of BPD.This may help us understand the pathogenesis of BPD, and may offer some new methods to prevent or cure BPD.

Comparative analysis of the prognosis of patients with locally advanced cervical cancer undergoing laparoscopic or abdominal surgery / 中华妇产科杂志

Objective:To compare the prognosis of patients with cervical cancer in stage Ⅰb2-Ⅱa2 undergoing laparoscopic radical hysterectomy or abdominal radical hysterectomy.Methods:From January 1, 2009 to December 31, 2018, patients with stage Ⅰb2-Ⅱa2 who underwent laparoscopic or abdominal radical hysterectomy (laparoscopic group and abdominal group) in Peking University People′s Hospital were collected. The clinicopathological data were retrospectively analyzed. There were 237 cases in this study, including 115 cases in laparoscopic group and 122 cases in abdominal group. The clinicopathological characteristics, surgery-related complications, recurrence and death were analyzed between the two groups. The related factors of recurrence and death were also analyzed.During laparoscopic surgery, the pressure of the carbon dioxide pneumoperitoneum were controlled, to try avoid the tumor tissue in the vagina from being exposed to the abdominal cavity when taking out the uterine specimen through the vagina, and fully flushed the abdominal cavity with sterile water after the specimen was taken out.Results:(1) Clinicopathological characteristics: there was no significant differences between the two groups among age, pathological type, pathological grade, clinical stage, depth of interstitial infiltration, lymph node metastasis,parametrial infiltration, vaginal stump infiltration, lymph-vascular space invasion (LVSI), neoadjuvant chemotherapy, and postoperative adjuvant treatments (all P>0.05). (2) Surgery-related complications: the incidence of surgery-related complications in the laparoscopic group and the abdominal group were 32.2% (37/115) and 25.4% (31/122), respectively. There was no statistically significant difference between the two groups ( P>0.05). (3) Recurrence and death: during the follow-up period, the recurrence rates of the laparoscopic group and the abdominal group were respectively 15.7% (18/115) and 12.3% (15/122). There was no statistically significant difference between the two groups ( P=0.456). The 5-year overall survival rates of the laparoscopic group and the open group were 86.8% and 87.8%, and the 5-year tumor-free survival rates were 81.7% and 84.6%, respectively. There were no statistically significant differences between the two groups ( P=0.405, P=0.429). (4) Analysis of related factors of recurrence and death: univariate analysis showed that neoadjuvant chemotherapy, lymph node metastasis, vaginal stump infiltration, LVSI and interstitial infiltration depth were risk factors for postoperative recurrence of cervical cancer patients (all P<0.05); neoadjuvant chemotherapy, lymph node metastasis, parametrial infiltration, vaginal stump infiltration, LVSI and interstitial infiltration depth were risk factors for postoperative death in patients with cervical cancer (all P<0.05). Multivariate analysis showed that neoadjuvant chemotherapy and lymph node metastasis were independent risk factors for postoperative recurrence and death of cervical cancer patients ( P<0.05). Conclusion:There is no significant difference in the prognosis of patients with cervical cancer in stage Ⅰb2-Ⅱa2 undergoing laparoscopic radical hysterectomy with non-touch operative technique and abdominal radical hysterectomy.

Effects of carbon monoxide release molecule-2 on sepsis-induced myocardial dysfunction in rats / 中华危重病急救医学

Objective@#To investigate the protective effect of carbon monoxide release molecule-2 (CORM-2) on sepsis-induced myocardial dysfunction in rats.@*Methods@#140 healthy male Sprague-Dawley (SD) rats were divided into sham operation (Sham) group, model group, CORM-2 pretreatment group, inactivated carbon monoxide release molecule-2 (iCORM) pretreatment group, and dimethyl sulfoxide (DMSO) control group by random number table, with 28 rats in each group. The rat sepsis model was reproduced by intraperitoneal injection of 10 mg/kg lipopolysaccharide (LPS). The rats in the Sham group were injected intraperitoneally with the same dose of normal saline (NS). The rats in the CORM-2 and iCORM-2 pretreatment groups were injected intraperitoneally with 8 mg/kg CORM-2 or iCORM-2 at 1 hour before LPS injection, respectively, and those in the DMSO group were injected intraperitoneally with the same dose of DMSO, but the rats in the Sham group and the model group were not treated after injection of NS or LPS. Twenty rats were randomly selected from each group to observe 10-day survival rate. Transthoracic echocardiography was performed on the remaining 8 rats at 12 hours after modeling, and the left ventricular ejection fraction (LVEF) and left ventricular fraction shortening (LVFS) were calculated to evaluate heart function. The blood of the inferior vena cava was harvested, then serum myocardial troponin I (cTnI) and brain natriuretic peptide (BNP) levels were measured by enzyme-linked immunosorbent assay (ELISA). Then the rats were sacrificed, and the myocardial tissues were harvested, the pathological morphology and ultrastructure of myocardium were observed.@*Results@#① Survival rates: all rats in the Sham group survived; compared with the Sham group, the survival rates of the model group, CORM-2 pretreatment group, iCORM-2 pretreatment group and DMSO control group were significantly decreased at 10 days [10% (2/20), 70% (14/20), 25% (5/20), 15% (3/20) vs. 100% (20/20), all P < 0.01]. However, the 10-day survival rate in the CORM-2 pretreatment group was significantly higher than those in the model group, iCORM-2 pretreatment group and DMSO control group (all P < 0.01). ② Cardiac function: compared with the Sham group, LVEF and LVFS in the model group, CORM-2 pretreatment group, iCORM-2 pretreatment group and DMSO control group were significantly decreased, and left ventricular dilatation was obvious, indicating myocardial dysfunction in rats. However, LVEF and LVFS in the CORM-2 pretreatment group were significantly higher than those in the model group, iCORM-2 pretreatment group, and DMSO control group [LVEF: 0.760±0.029 vs. 0.634±0.021, 0.629±0.066, 0.673±0.023; LVFS: (39.32±2.38)% vs. (29.75±1.52)%, (29.61±4.15)%, (32.43±1.66)%, all P < 0.05], and the left ventricular dilatation in the septic rats was attenuated. ③ Myocardial injury markers: compared with the Sham group, serum cTnI and BNP levels were significantly higher in the model group, CORM-2 pretreatment group, iCORM-2 pretreatment group and DMSO control group. However, the levels of cTnI and BNP in the CORM-2 pretreatment group were significantly lower than those in the model group, iCORM-2 pretreatment group and DMSO control group [cTnI (ng/L): 3 283.54±803.50 vs. 6 449.18±1 105.10, 5 919.21±1 068.27, 6 349.80±1 153.08; BNP (ng/L): 3 456.62±905.85 vs. 6 070.18±1 287.62, 5 581.13±1 161.17, 5 974.89±988.89, all P < 0.05]. ④ Myocardial histopathological observation: optical microscope showed that the pathological changes in myocardial tissue of the model group, iCORM-2 pretreatment group and DMSO control group were severe. Transmission electron microscopy showed mitochondrial swelling, and some vacuoles changed. But the myocardial pathological morphology and mitochondrial ultrastructural integrity of the CORM-2 pretreatment group were significantly better than other groups of sepsis.@*Conclusion@#CORM-2 can attenuate myocardial dysfunction and improve survival rate of septic rats, especially to protect myocardial mitochondrial integrity in sepsis.

Pulmonary vascular development,diagnosis and treatment for pulmonary hypertension in preterm in-fants with bronchopulmonary dysplasia / 中国小儿急救医学

It is well known that pulmonary hypertension(PH) is one severe complication of bron-chopulmonary dysplasia( BPD) that is associated with high mortality. Aberrant pulmonary vascular growth, abnormal vasoreactivity and pulmonary vascular remodeling may ultimately lead to PH. Symptoms of PH of-ten overlap those of BPD itself. Furthermore,the emergence of symptoms may indicate that the disease has already progressed to a late, less reversible phase, thereby supporting arguments for screening all infants at risk. Echocardiography is non-invasive and widely available,and is currently the most commonly used screen-ing modality for PH in infants with BPD. Because the incidence of associated cardiovascular anomalies is high,cardiac catheterization and CT scanning of the chest should be considered in all infants who have signifi-cant PH despite optimal management of their lung disease. Early diagnosis and aggressive specific drug thera-py can improve the outcome for these patients.

Persistent pulmonary hypertension of newborn (PPHN) is a clinical syndrome,characterized by pulmonary arterial pressure elevated relative to systemic blood pressure,leading to extrapulmonary right-to-left shunting of blood across the ductus arteriosus and foramen ovale,causing severe hypoxemia.Pulmonary vascular remodeling is pathognomonic of hypoxia-induced PPHN.The regulatory mechanism and cell composition of vascular wall were dysfunction,which led to vascular wall thickened.The review focus on three aspects,such as endothelial cells,smooth muscle cells,and adventitial cells,described the relation and the possible mechanisms between hypoxia-induced PPHN and pulmonary vascular remodeling.

Study of morphological alterations in pharyngeal ostium of Eustachian tube and its surrounding tissue and its association with SOM / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To observe the morphological alterations in pharyngeal ostium of Eustachian tube and its surrounding tissues and its correlation with secretory otitis media.@*METHOD@#72 volunteers (144 ears) as control group, 89 patients (151 ears) as SOM group, all were observed for the shape of pharyngeal opening of auditory tube and the morphological changes of its surrounding structures.@*RESULT@#Statistic difference was found between the shape of pharyngeal ostium of eustachian tube of adult patients with SOM and that of control group, but for children, there was no difference. It indicated that there was a difference between adult and children in morphological changes of pharyngeal ostium of eustachian tube when suffered from SOM.@*CONCLUSION@#Morphological changes of pharyngeal ostium of eustachian tube play an important role in the genesis and development of adult SOM . The primary change in children patients is the inflammation of nasopharynx, then is the hypertrophy of adenoid and tubal tonsil. Nasopharyngeal-fibroscope is a very useful tool in the diagnosis and treatment of SOM.
