In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management. Through the synthesis and discussion of these topics, this article seeks to provide a detailed analysis of the current landscape of interventional treatment for CHD in China and project its future development trends.

Objective To explore the effect of KIAA0753 on glucose and energy metabolism in mouse embryonic osteoblast precursor cell line MC3T3-E1.Methods The GSE182286 datasets of patients with Joubert syndrome acquired from the Gene Expression Comprehensive database were analyzed for the levels of gene expression.After the cells with KIAA0753 overexpression were constructed and the experiment were divided into the control group,the high glucose group and the high glucose+overexpression KIAA0753 group,Western blotting was used to determine the effect of KIAA0753 on MC3T3-E1 cells under high glucose condition by detecting the expression of the glucose metabolism-related proteins,such as glycogen synthase 1 (GYS1 ),glycogen phosphorylase L (PYGL ),glucose transporter type 4 (GluT4 ),phosphofructokinase muscle (PFKM),pyruvate dehydrogenase phosphatase 1 (PDP1 ),and acetyl-CoA carboxylase α(ACACA ),as well as the mitochondria function-associated proteins,including peroxisome proliferator-activated receptor-γcoactivator-1α(PGC-1α),nuclear respiratory factor 1 (NRF1 ),and mitochondrial transcription factor A (TFAM).The effect of KIAA0753 on the intermediates of glucose metabolism was analyzed by determining the contents of glycogen,glucose and lactic acid in the cell culture medium.Cellular immunofluorescence assay and adenosine triphosphate (ATP ) assay were employed to measure the mitochondrial activity and function impacted by KIAA0753 in the cells under high glucose condition.The effect of KIAA0753 on the proliferation of MC3T3-E1 cells under high glucose was detected by EdU staining. Results The expression of KIAA0753 protein was downregulated in patients with Joubert syndrome and in MC3T3-E1 cells under high glucose conditions (P<0.05).High glucose resulted in inhibited protein expression of GYS1,ACACA,PFKM,GluT4,PGC-1α,TFAM and NRF1,enhanced protein levels of PDP1 and PYGL,reduced glycogen generation and consumption of extracellular glucose,and promoted production of lactic acid (P<0.05 ).While,overexpression of KIAA0753 could attenuate the effect of high glucose,that is,up-regulating the protein expression levels of GYS1,ACACA,PFKM,GluT4,PGC-1α,TFAM and NRF1,suppressing those of PDP1 and PYGL,enhancing glycogen generation and consumption of extracellular glucose,and inhibiting production of lactic acid (P<0.05 ). What's more,the overexpression also could elevate the activity and membrane potential of mitochondria,and promote the ATP synthesis (P<0.05 )and cell proliferation (P<0.05)in MC3T3-E1 cells under high glucose.Conclusion KIAA0753 can promote glucose metabolism and improve mitochondrial activity and function in osteoblasts,consequently providing more energy to the body.

Objective:To explore the clinical and electrophysiological characteristics of flail arm syndrome (FAS).Methods:Clinical and electrophysiological data were collected on 13 FAS patients and 31 persons with upper limb onset amyotropic lateral sclerosis (UL-ALS), including the amplitude of compound muscle action potential (CMAP) related to median nerve, ulnar nerve, and axillary nerve motor conduction. A split-hand index (SI) was calculated by dividing the CMAP amplitude of abductor pollicis brevis by that of the abductor digiti minimi. Clinical features, the CMAP amplitudes and SIs were compared between the FAS and UL-ALS patients.Results:Compared with UL-ALS patients, the age at onset among the FAS patients was older (averaging 60.9 years). The development to the second stage was longer (24±6 months). The upper limb reflexes of 15% of the FAS patients had disappeared and those of 77% were weakened, while the lower limb reflexes of 54% of the FAS patients were active and 38% were weakened, significantly different from the UL-ALS patients. However, there were no significant differences in the CMAP amplitudes of the median and ulnar nerves, nor in SI between the FAS and UL-ALS patients. The SIs of the FAS patients with upper motor neuron signs were significantly lower than those of FAS patients without such signs. Among the FAS patients, the average CMAP amplitude of the ulnar nerve was the highest, followed by those of the median and axillary nerves. Among the UL-ALS patients, however, the average CMAP amplitude of the ulnar nerve was not significantly different from that of the axillary nerve.Conclusions:FAS patients with upper motor neuron signs are more likely to have slip hand. The CMAP amplitude of their axillary nerve tends to be lower than that of their median and ulnar nerves. FAS seems to be a special type of ALS.

Objective:To investigate the effect of anterior or posterior debridement on infections of the lumbar vertebral fusion with cage and pedical screw system.Methods:A total of 10 cases (3 males and 7 females, age 49.80±13.29 years) with infections in the lumbar fusion device were admitted from January 2013 to December 2019. The cases were diagnosed with deep infections after the preview surgery at 10.80±13.24 months, including 10 cases with 12 cages infections and 8 cases with screw system infections. 7 cases were done with debridement and removal of the cages via the anterior approach. And another 3 cases underwent posterior debridement and removal of lumbar fusion cages. The changes in laboratory examination such as WBC count, ESR, CRP, visual analogue scale (VAS) and Oswestry Disability Index (ODI) score were compared preoperatively, 2 months and 6 months postoperatively.Results:No patients were lost in the follow-up. The average follow-up time periods is 16.30±5.10 months (range 9-24 months). There was no significant difference in WBC count between 2 and 6 months after surgery compared with preoperation ( F=0.855, P=0.436). The ESR, CRP, VAS and ODI scores decreased in 2 months and 6 months after sugery, which has significant differences compared preoperation ( P<0.05). The abnormal signals in the lambar vertebral showed a gradual fading trend in the postoperative MRI. The completely fading time was 5.00±1.33 months (range 3-7 months). One-stage bone grafting was performed in 6 cases with 8 spaces via anterior approach, 5 cases with 7 spaces showed the intervertebral fusion after postoperative with 6.80±2.28 months (range 4-10 months), 1 case wirh 1 space was not fused. One-stage bone grafting was performed in 2 cases via posterior approach: 1 case was fused after postoperative and the other patient was not, which due to bone graft area infection. Postoperative bone graft displacement occurred with 1 case and 1 case with L 5 nerve root pulling injury during the operation. Conclusion:The fusion cage can be removed by debridement via posterior approach, but it is difficult to done the completely debridement, which the main reason is the obstruction of the posterior nerve and bone structure. Posterior approach also have risks of infection recurrence and nerve root injury. Cage removal via anterior approach was relatively easy and debridement was thoroughly, which has the risk of injury of important adjacent vessels.

Objective: To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES). Methods: This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio. Results: A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score. Conclusion The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.

Objective: To explore the effect of post-abortion care service based on Wechat follow-up on contraceptive compliance of multiple induced abortion patients, and to evaluate the satisfaction with PAC service. Methods: A quasi-experimental method was adopted. A total of 300 cases of induced abortion were selected in Beijing Obstetrics and Gynecology Hospital affiliated to Capital Medical University from March 2018 to March 2019, with 150 cases from eastern branch in the experimental group and 150 cases from western branch in the control group. The control group received routine nursing care and post-abortion care service based on telephone follow-up, while the experimental group received routine nursing care and post-abortion care service based on Wechat follow-up. The missing rate of follow-up, the contraceptive method and the occurrence of unexpected pregnancy within one year after operation were collected in the two groups. Patients′ follow-up compliance and nursing satisfaction were evaluated. Results: The awareness of the risk of induced abortion in the experimental group was 90.4% (120/135) higher than that in the control group 77.5% (88/111), and the difference was statistically significant (χ² value was 9.128, P=0.010). The contraceptive consciousness of the two groups was 99.3% (134/135) and 94.6% (105/135), respectively, and the difference was not statistically significant (χ² value was 3.256, P=0.071). There was a statistically significant difference in the missing rate of follow-up between the two groups in January, March, June, and December (χ² value was 13.664, P=0.003). Compared with 19.8% (22/111) in the control group, 73.3% (99/135) patients in the study group chose high-efficiency contraception, the difference was statistically significant (χ² value was 69.795, P<0.01).There were no recurring pregnancies in the experimental group within one year, compared with 6.3% (7/111) in the control group, the difference was statistically significant (χ² value was 6.630, P=0.003). In the experimental group, the participation rate of the follow-up were (95.37±12.29)%, which were higher than that in the control group (90.77±16.49)%. The difference was statistically significant (t value was 2.438, P<0.05). The overall satisfaction score of the experimental group was 26.55 ± 2.80, which was higher than that of the control group (23.66 ± 3.32). The difference was statistically significant (t value was 7.285, P <0.01). Conclusion Post-abortion care service based on Wechat follow-up could enhance patients′ compliance and satisfaction, guide patients to choose the right contraceptive methods, reduce the rate of repeated abortion and promote female reproductive health.

Objective: To understand the results of tuberculin skin test (PPD) in preschool children after the vaccination of BCG, and to analyze the effect of BCG vaccination on latent tuberculosis infection in children. Methods: From January to November 2018, a total of 1 359 preschool children from 14 kindergartens in 8 districts and cities of Jiangsu Province were selected for tuberculin test(PPD), and chest X-ray examination was performed on children with strong PPD results. Results: The positive rate of PPD in preschool children in Jiangsu Province was 23.33%, of which strong positive and moderate positive (PPD≥10 mm) were totaled 6.47%. There were 149 boys (21.29%) with PPD positive reactions and 168 girls(25.50%) with PPD positive reactions, and differences of PPD positive reactions with different genders were of no statistical significance (χ2=3.36, P>0.05) And there were 201 children (25.35%) with PPD positive reactions in northern Jiangsu, 116 children (20.50%) with PPD positive reactions in southern Jiangsu. There were significant differences in the results of PPD positive and negative reactions between different regions(χ2=4.35, P<0.05). There was 1 case of PPD positive reactions among 3-year-old children(0.71%), 19 cases among 4-year-old children(3.89%), 31 cases among 5-year-old children(8.96%), and 37 cases among 6-year-old children(9.63%), and the differences of PPD positive reactions of different age groups were of statistical significance(χ2=21.69, P<0.01). Conclusion The positive rate of PPD in preschool children in Jiangsu Province is very low, indicating that PPD can be used as a detection method for latent infection in children. The overall positive rate of PPD in preschool children in Jiangsu Province is also low, and appropriate measures should be taken to protect susceptible children and effectively prevent and control childhood tuberculosis.

OBJECTIVETo investigate the effects of isoliquiritigenin on the migration and invasion of human glioma stem cells and the underlying mechanism.

METHODSThe stem cell markers CD133 and Nestin in SHG44 human glioma stem cells were examined with immunofluorescence microscopy. The migration and invasion ability of glioma stem cells was determined by transwell method. The mRNA and protein expression of matrix metalloproteinase (MMP)-2 and MMP-9 were detected by real-time RT-PCR and Western blot, respectively.

RESULTSCD133 and Nestin were positive in SHG44 cells. The number of migrated cells in SHG44 cells treated with 20 and 80 μmol/L isoliquiritigenin for 48 h were significantly lower than that in control group (76±5 and 42±4 vs. 85±6, all <0.01), and the number of migrated cells in 80 μmol/L isoliquiritigenin group was lower than that in 20 μmol/L isoliquiritigenin group (<0.01). The numbers of cells crossing through membrane in 20 and 80 μmol/L isoliquiritigenin groups were 190±13 and 130±9, respectively, which were significantly lower than that in control group (230±14, all <0.01), and the number of crossed cells in the 80 μmol/L isoliquiritigenin group was lower than that in 20 μmol/L isoliquiritigenin group (<0.01). The mRNA and protein expression levels of MMP-2 and MMP-9 were decreased compared with control group (<0.05 or <0.01), and the expression levels in 80 μmol/L isoliquiritigenin group were lower than those in 20 μmol/L isoliquiritigenin group (<0.05 or <0.01).

CONCLUSIONSIsoliquiritigenin exhibits antitumor effects on glioma stem cells by inhibiting cell migration and invasion, which may be related to the down-regulation of MMP-2 and MMP-9.

Objective: To investigate the effect of knee-chest position on exhaust and defecation of gynecologic diseases patients after laparoscopic surgery. Methods: This quasi-experiment trail was conducted between July 2016 to May 2017, in a birth control ward at an obstetrics and gynecology hospital in Beijing, China. The study included a total of 258 patients who had gynecological benign diseases and received gynecological laparoscopic surgery. Participants were recruited in the trail by using a convenient sampling method with 130 patients who received gynecological laparoscopic surgery from July 2016 to December 2016 in the experimental group (on the basis of routine care, patients preformed a knee-chest position intervention after 6 hours of the surgery) and 128 patients who received gynecologic laparoscopic surgery between January 2017 and May 2017 in the control group (patients received a routine care). The primary end point was the postoperative anal exhaust. Results: The ambulation rate before post-operative ventilation of the experimental group was 21.5% (28/130) less than that of the control group (91.4%, 117/128). The difference was statistically significant (χ²=127.903, P<0.01). The incidence of abdominal distension after operation was 0, lower than that of the control group 7.0% (9/128), the difference was statistically significant (χ²=9.471, P<0.01). The postoperative exhaust time and defecation time of the experimental group was (8.17 ± 2.88) h,(27.86 ± 4.29) h, earlier than that of the control group, (21.24 ± 5.90) h,(38.69 ± 7.73) h, and the differences were statistically significant (t=22.580, 13.885, P<0.01). Conclusions Postoperative knee-chest position significantly improved the exhaust and defecation of patients with gynecological benign disease after laparoscopic surgery.

Objective To investigate the clinical effects of Dexmedetomidine on analgesia and postoperative cognitive function in elderly patients with lumbar spine surgery.Methods The patients were randomly divided into the control group (n=88) and the study group (n=100).The patients in the study group were treated with Dexmedetomidine at a loading dose of 1.0 μg/kg for 15 min,and 0.3 μg · kg-1 · h 1 was continuously pumped.The anesthetic mode and drugs in the control group were similar to those in study group,except that Dexmedetomidine in the study group was replaced with physiological saline in the control group.Intraoperatively used dose of analgesic drugs,and pain and cognitive function changes were compared between the two groups.Results The intraoperatively used doses of Remifentanil,Fentanyl and propofol were significantly lower in the study group than in the control group (P＜0.05).The VAS scores were markedly lower in the study group than in the control group (2.6±0.5 vs.4.5± 1.2,t=4.9398,P=0.0000).The MMSE scores were higher in the study group than in the control group (28.0 ± 1.3 vs.26.0 ± 2.5,t =-6.6484,P=0.0000).Conclusions Intraoperative use of Dexmedetomidine for treatment of the elderly patients with lumbar surgery will not only reduce the perioperatively used dose of analgesic and sedative drug,but also reduce postoperative pain and improve postoperative cognitive function.
