ABSTRACT
Objective:To explore the factors influencing the clinical outcome of complex high-risk indicated patients percutaneous coronary intervention (CHIP-PCI) assisted by extracorporeal membrane oxygenation (ECMO).Methods:The clinical data of patients with CHIP-PCI assisted by ECMO in the First Affiliated Hospital of Zhengzhou University from April 2018 to April 2022 were retrospectively collected and analyzed. Patients were divided into the survival and death groups according to the in-hospital survival status. The baseline characteristic, the results of coronary angiography, and the use of ECMO, blood products and drug were compared between the two groups. The 24-h rate of change of biochemical test indicators after the use of ECMO were calculated and the univariate analysis was analyzed using rank sum test. According to the univariate analysis, the variables ( P<0.05) were included in multivariate logistic regression to analyze the factors affecting the clinical outcomes of patients. Results:A total of 67 CHIP patients who completed PCI with ECMO were included. In the survival group ( n=36), the duration of ECMO treatment was 59 (41, 87) h, 9 cases received continuous renal replacement therapy, and 11 cases received IABP. In the death group ( n=31), the duration of ECMO treatment was 31 (19, 80) h, 12 cases received continuous renal replacement therapy and10 cases received IABP. The proportion of patients with chronic total occlusion lesions (CTOs) in the survival group was lower than that in the death group, the duration of ECMO of the survival group was longer than that of the death group ( P<0.05). Multivariate logistic regression analysis showed that 24-h lactate change rate ( OR=2.864, 95% CI: 1.185-6.918, P=0.019), 24-h eGFR change rate ( OR=0.050, 95% CI: 0.003-0.871, P=0.040), 24-h D-dimer change rate ( OR=1.497, 95% CI: 1.044-2.146, P=0.028) and 24-h direct bilirubin change rate ( OR=2.617, 95% CI: 1.121-6.111, P=0.026) were associated with in-hospital mortality. Conclusions:Within 24 h after CHIP-PCI assisted by ECMO, the rapid decline in lactic acid, D-dimer and direct bilirubin, and the rapid recovery of eGFR, are associated with the decreased risk of hospital mortality from CHIP.
ABSTRACT
Objective:The clinical manifestations, types of gene mutations, therapeutic effects and prognostic characteristics of 15 children with cblC type methylmalonic acidemia (MMA) and hydrocephalus were analyzed to improve the clinical understanding of the disease, so as to provide a basis for the treatment of the disease.Methods:From April 2015 to January 2019, 15 patients with MMA and hydrocephalus in Department of Pediatric Surgery, Peking University First Hospital were enrolled, and all gene detection showed clbC type.All the 15 patients underwent ventriculoperitoneal shunt.After surgery, the clinical manifestations and imaging findings were applied as the basis to adjust the pressure of the diverter valve appropriately.Clinical data and gene mutation characteristics of 15 children with cblC type and hydrocephalus were retrospectively analyzed, and the therapeutic effects and prognosis were summarized and analyzed as well.Results:There were 8 males (53.3%) and 7 females (46.7%), aged from 2 to 33 months.All the cases were followed up from 11 to 55 months, without death case and serious postoperative complications of hydroce-phalus.The head circumference of 3 cases (20.0%) was in the normal range, 1 case (6.7%) was greater than the normal range, and 11 cases (73.3%) were less than the normal range.Four patients (26.7%) were transferred to the pediatric intensive care unit after surgery.c.609G>A mutation was the most common in this study, with 7 cases (46.7%) of c. 609G>A homozygous mutation, and 5 cases (33.3%) of c. 609G>A heterozygous mutation.Clinical symptoms of intracranial hypertension were relieved or disappeared.The head circumference progressive enlargement was stopped.The anterior fontanelle tension greatly decreased, all " setting-sun" sign of eyes disappeared, and vision loss and hearing loss were better compared with the pre-operation.Four cases (26.7%) displayed normal intelligence and exercise, and 11 cases (73.3%) were left with mild to severe psychomotor retardation.During the follow-up pe-riod, the head CT showed that the ventricle was remarkably narrowed, and interstitial brain edema obviously improved.Conclusions:Ventriculoperitoneal shunt in the treatment of cblC type MMA with hydrocephalus has positive effects.The head circumference of most cblC type MMA with hydrocephalus is less than the normal range.c.609 G>A is the most common mutation in cblC type MMA with hydrocephalus.Perioperative " metabolic crisis" can result in serious complications.

Conclusions:All patients have a certain degree of relief after DBS without obvious adverse reactions.DBS is an effective treatment for pediatric dystonia.
ABSTRACT
OBJECTIVE@#To study the effect of down-regulating miR-488 targeting Jag1 on the injury of hypoxia-reoxygenation myocardial H9c2 cells.@*METHODS@#A hypoxic-reoxygenated myocardial H9c2 cell injury model was constructed. miR-488 inhibitor was used to transfect the cells. CCK-8 method and flow cytometry were used to detect cell proliferation and apoptosis in each group. Lactate dehydrogenase (LDH), superoxide dismutase (SOD), malonaldehyde (MDA), catalase (CAT) levels were detected. Western blotting was used to detect the expression of Bcl-2 associated X Protein (Bax) and B cell lymphoma/lewkmia-2 (Bcl-2). Target genes of miR-488 were predicted, and a luciferase reporter system was used to verify the targeting relationship between the two. Myocardial H9c2 cells were co-transfected with miR-488 inhibitor and Jag1 siRNA, and treated with hypoxia and reoxygenation, cell proliferation, apoptosis, LDH, SOD, MDA, CAT levels, and Bax, Bcl-2 protein expression were detected.@*RESULTS@#The expression of miR-488 in the hypoxia-reoxygenated myocardial H9c2 cells was increased, along with reduced cell proliferation, increased apoptosis, increased Bax protein expression, decreased Bcl-2 protein expression, increased MDA, decreased CAT and SOD, and increased LDH level in the supernatant of cell culture. When myocardial H9c2 cells were transfected with miR-488 inhibitor and treated with hypoxia and reoxygenation, the expression of miR-488 was decreased, along with increased cell proliferation, decreased apoptosis, decreased Bax protein expression, increased Bcl-2 protein expression, decreased MDA, increased CAT and SOD, and decreased LDH level in the supernatant of cell culture. Down-regulation of miR-488 could target and down-regulate Jag1 expression. And Jag1 siRNA could reverse the effect of miR-488 inhibitor on the proliferation, apoptosis, LDH, SOD, MDA, CAT levels and the expression of Bax and Bcl-2 of hypoxic-reoxygenated myocardial H9c2 cells.@*CONCLUSION@#Down-regulating miR-488 targeted Jag1 can attenuate hypoxia-reoxygenation induced myocardial H9c2 cell injury.

OBJECTIVE@#To explore the effect and mechanism of miR-125a-5p targeted regulation of scavenger receptor B1 (Scarb1) gene on anoxia/reoxygenation injury of rat cardiomyocytes.@*METHODS@#H9c2 rat cardiomyocytes were randomly divided into blank control group, hypoxia/reoxygenation group, transfection control group and mir-125a-5p transfection group. The expression of miR-125a-5p, cardiomyocyte viability, apoptosis rate, ATP content and the expression of Scarb1, Cyt C, Bax, Bcl-2 and NF-κB signaling pathway related proteins were determined. Target gene of miR-125a-5p was predicted with Targetscan software, and the targeting of miR-125a-5p on Scarb1 was verified by double luciferase reporter gene experiment.@*RESULTS@#Compared with the blank control group, the expression of miR-125a-5p, Bax, Cyt C and the apoptotic rate of cardiomyocytes in the hypoxia/reoxygenation group were significantly increased (P<0.05), while the expression of Scarb1, Bcl-2 and the content of ATP were significantly decreased (P<0.05). Compared with the control group, the situation of mir-125a-5p transfection group was just the opposite. Double luciferase reporter gene experiment has confirmed Scarb1 to be the target of miR-125a-5p. Hypoxia/reoxygenation can promote the expression of NF-κB p65, C-myc and Cyclin D1 in cardiomyocytes, while down-regulating the expression of miR-125a-5p can inhibit the expression of such proteins.@*CONCLUSION@#Hypoxia/reoxygenation can induce the expression of miR-125a-5p in rat cardiomyocytes. Inhibition of miR-125a-5p can protect cardiomyocytes from hypoxia/reoxygenation by up-regulating the expression of Scarb1. The mechanism may be related to the inhibition of activation of NF-κB signaling pathway.
ABSTRACT
In the past 30 years, with the advancement of functional neurosurgery, neuroelectrophysiology and neuroimaging, deep brain stimulation (DBS), as a new tool for the treatment of dyskinesia, has been considered to have underwent the fastest development in this field.Many patients with dyskinesias have significantly improved their main clinical symptoms after treatment with DBS, some of the improvement are even dramatic.Due to its minimally invasive characteristics, reversibility and adjustability, DBS therapy has been increasingly used in the treatment of dystonia in children.Hereditary dystonia is the most common type of dyskinesia in children, and there is no effective treatment yet.Recently, some dyskinesia at home and abroad centers have carried out DBS treatment for pediatric hereditary dystonia and achieved some encouraging results.Now, the effect of DBS in the treatment of hereditary dystonia in children and the main process of DBS treatment were mainly discussed, and shared the experience based on the clinical practices of Multidisciplinary Collaborative Diagnosis and Treatment Center for Children′s Motor Disorders, Peking University First Hospital.

AIM:To explore the effect of Toll-like receptor ( TLR) 2 and TLR4 in Mycobacterium bovis Bacil-lus Calmette-Guérin (BCG)-induced human proximal renal tubule epithelial cell (HK-2) injury.METHODS:HK-2 cells were stimulated by BCG, and the expression of TLR2, TLR4, chemokine (C-X3-C motif) ligand 1 (CX3CL1) and trans-forming growth factor beta 1 ( TGF-β1 ) was detected by quantitative real-time PCR and Western blotting .TLR2 monoclonal antibody and TLR4 inhibitor were used to treat the HK-2 cells 1 h before BCG stimulation.The expression of CX3CL1 and TGF-β1 was evaluated by quantitative real-time PCR and Western blotting .RESULTS: BCG increased the expression of TLR2, TLR4, CX3CL1 and TGF-β1 in the HK-2 cells.Additionally, the expression of CX3CL1 and TGF-β1 was inhibited partly by TLR2 monoclonal antibody or TLR4 inhibitor.CONCLUSION:BCG is able to increase the production of TLR 2, TLR4, CX3CL1 and TGF-β1 in the HK-2 cells.TLR2 and TLR4 signaling pathways play important roles in tubule epitheli-al cell injury induced by BCG .
ABSTRACT
Thirty-two male Sprague-Dawley rats were divided into control group (n =16) and fructose group (n =16) fed with 10％ fructose solution.After 4 weeks,the rats of two groups were treated with saline and 50 nmol/kg ghrelin for 6 weeks,respectively (each group n =8).Fasting plasma glucose,insulin,and blood lipid profile were measured.Insulin receptor (Ins-R) mRNA expression in muscle was detected by RT-PCR.The phosphorylation of insulin receptor substrate-1 (IRS-1) was measured by Western blot.The results showed that insulin level and homeostasis model assessment for insulin resistance index (HOMA-IR) in fructose group were higher than those in control group [(13.1±3.6 vs 9.0 ± 1.5) μU/ml,P＜0.05 ;2.78 ± 0.14 vs 1.81± 0.13,P ＜0.01)].After ghrelin treatment,plasma insulin concentration [(9.6 ± 2.5) μU/mL,P＜0.05] and HOMA-IR (1.96 ± 0.12,P＜0.01)significantly decreased,along with increased Ins-R mRNA and IRS-1 phosphorylation in skeletal muscle (P ＜0.01).These results suggest that ghrelin can ameliorate insulin resistance in fructose-fed rats by restoring Ins-R function.
ABSTRACT
OBJECTIVE@#This study evaluates the effects of H-uvulopalatopharyngoplasty (H-UPPP) on endothelial function by endothelium dependent flow-mediated dilation(FMD) in patients with moderate to severe obstructive sleep apnea syndrome (OSAHS).@*METHOD@#Forty-five healthy subjects and 49 patients with moderately to severe OSAHS who desired H-UPPP were prospectively enrolled. FMD was measured by high-resolution B-mode ultrasonography. All subjects participated in sleep studies. These studies were repeated 6 months after H-UPPP in patients with moderately to severe OSAHS.@*RESULT@#There was significant difference in FMD between patients with moderately to severe OSAHS and healthy subjects at baseline (6.5 +/- 2.1)% vs (11.2 +/- 3.1)% (P < 0.01). FMD increased from (6.5 +/- 2.1)% to (9.7 +/- 2.7)% 6 months after H-UPPP in patients with moderately to severe OSAHS (P < 0.01).@*CONCLUSION@#FMD is decreased in patients with moderately to severe OSAHS, H-UPPP treatment of these patients leads to improvement of FMD.
