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.

Aim To investigate the possible mechanism of action of Qingjie Huagong decoction(QJHGD)on acute lung injury(ALI)associated with severe acute pancreatitis(SAP)using network pharmacology,and to verify it by animal experiments.Methods The TC-MSP,BATMAN-TCM,ETCM,and SwissTargetPredic-tion databases were searched to obtain the action tar-gets of the blood-entering active ingredients of each drug in the QJHGD.The GeneCard database was searched to obtain SAP-ALI disease targets.The drug targets and disease targets were intersected to obtain common targets.Subsequently,the common targets were analyzed by STRING database and Cytoscape 3.7.1 software for protein interaction network analysis.GO and KEGG enrichment analysis was performed with the help of DAVID database.Finally,the key signa-ling pathways were verified by animal experiments.Results A total of 28 active ingredients were screened out for the treatment of SAP-ALI with 42 common tar-gets.PPI network analysis showed that STAT3,IL-6,and TGFB1 might be core targets;GO and KEGG en-richment analysis mainly involved cell proliferation,PI3K/AKT signaling pathways,etc.Animal experi-ments confirmed that QJHGD could improve the pathol-ogy of pancreas and lung tissues in SAP-ALI rat mod-el,down-regulate the expression levels of α-amylase,lipase,IL-1 β,IL-6,and TNF-α in serum,and down-regulate the expression levels of proteins and mRNAs related to PI3K/AKT1 signaling pathway in lung tis-sues.Conclusion QJHGD synergistically treats SAP-ALI through multi-component,multi-target,and multi-pathway,with a mechanism that may be related to the inhibition of PI3K/AKT signaling pathway activation.

Objective To investigate the effect of nasal mask on preventing respiratory depression and hypoxia during anesthesia under painless gastroscopy.Methods 246 patients underwent elective painless gastroscopy from September 2022 to March 2023 were selected and divided into nasal catheter oxygen group(group C)and nasal mask oxygen group(group M)according to random number table method.The group C was inhaled oxygen by conventional nasal cannula,and in group M,oxygen was inhaled by a nasal mask.Patients in both groups were given 5 L/min preoxygenation for 3 min.After induction of anesthesia,gastroscopy was performed when modified observer's assessment of alertness/sedation(MOAA/S)score≤1.During anesthesia,hypoxia interventions were performed in group C based on percutaneous arterial oxygen saturation(SpO2)and in group M based on partial pressure of end-tidal carbon dioxide(PetCO2)and SpO2.The incidence of subclinical respiratory depression,hypoxia and severe hypoxia during anesthesia was recorded.The minimum SpO2 value during anesthesia was recorded;Implementation of intervention measures of jaw lifting,mask pressure oxygen and tracheal intubation.Record the number of gastroscope withdrawal cases.Mean arterial pressure(MAP),heart rate(HR),and respiratory rate(RR)were recorded at the time of entry(T0),immediately after induction of anesthesia(T1),at the end of gastroscopy(T2),and 5 minutes after awakening(T3).The occurrence of perioperative adverse events and the satisfaction of anesthesiologists and endoscopists were recorded.Results Compared with group C,the incidence of subclinical respiratory depression,hypoxia and severe hypoxia in group M was significantly decreased(P<0.05).The minimum value of SpO2 during anesthesia in group M was higher than that in group C(P<0.05).The incidence of jaw-lifting and mask ventilation were lower in group M than that in group C(P<0.05).The incidence of gastroscope withdrawal due to airway intervention in group M was lower than that in group C(P<0.05).Compared with T0,MAP,HR and RR of the two groups were significant reduction at T1 and T2(P<0.05).There was no significant difference in the incidence of adverse events between the two groups(P>0.05).The satisfaction of endoscopists in group M was higher than that in group C(P<0.05).Conclusion Compared with nasal catheter oxygen inhalation,anesthesia nasal mask can timely detect hypopnea and respiratory depression during gastroscopy,reduce the occurrence of hypoxia,and improve the airway safety of painless gastroscopy patients.

This study was aimed at exploring the epidemiological characteristics of plague,and the evolutionary relation-ships among the isolated plague strains in the Yunnan border area,to provide clues for further studying epidemic causes and ep-idemiological patterns.Plague epidemic data in the border area during the second epidemic period(1982-2007)were collected and analyzed with descriptive epidemiological methods.Whole genome sequences of 262 strains of Yersinia pestis in the border area were obtained for phylogenetic analysis.Plague outbreaks occurred in 17 counties(cities)among 25 border counties(cit-ies);a total of 552 epidemic foci and 123 human cases were identified.The 1.ORI2,1.ORI3,1.IN3,2.ANT and 2.MED geno-types were identified among Yersinia pestis isolated from the Yunnan border area,among which the 1.ORI2 population was dominant.A total of 258 strains of Yersinia pestis from the 1.OR12 population belonged to four subclusters.The Myanmar and Vietnam clade was embedded within the Yunnan clade in the overall phylogeny.The above results indicated that during the sec-ond period of the epidemic,the intensity of plague epidemics in Yunnan's border areas was high,showing a trend of devel-opment from west to south and east.Our findings indicated a risk of cross-border transmission of plague between Yunnan and neighboring countries;therefore,the surveillance,pre-vention,and control of plague in border areas should be strengthened.

Objective:To explore the clinical effects of free anterolateral thigh perforator flap (ALTPF) with modified cross-leg vessel bridging in reconstruction of infected wounds in the lower leg combined with major vessel defects.Methods:A retrospective observational study was conducted on 7 patients who admitted to the Department of Trauma Orthopaedics, the 521 Hospital of Norinco Group from January 2020 to December 2021 for treatment of large infected wounds in lower leg with soft tissue defect by reconstructive surgery of flap transfer. The patients were 5 males and 2 females, aged 23-50 years old with an average age of 37 years old. The causes of injury were: 5 patients were of car accidents, 1 of machinery compression and 1 of heavy object crush. The wounds were reconstructed after debridement and infection control with sensitive antibiotics, where the soft tissue defects were found at 11.0 cm×15.0 cm to 20.0 cm×32.0 cm in size. All patients underwent vascular angiography or CDU examinations and it was confirmed that the affected calf had only an anterior tibial artery as the vessel left for blood supply in 6 patients and a posterior tibial artery as the blood supply vessel in one patient. Therefore application of vascular end-to-side anastomosis in free flap reconstruction of limb defects was impossible due to the damaged artery could not be salvaged as a blood supply artery for the transferred flap. Therefore, a modified cross-leg vessel bridging to the freed ALTPF in the affected lower leg was applied. The donor site of the pedicle was covered with VSD while the pedicle of the flap was anastomosed. It was remained until the posterior tibial artery and the tubular flap were ready for replantation after disconnection of the pedicle. The sizes of flap were 13.0 cm×17.0 cm to 22.0 cm×32.0 cm (unilateral ALTPFs for 6 patients and bilateral ALTPFs for 1 patient). Two donor sites in low tension were direct closed, and the rest of 5 donor sites that had great tensions and could not be directly sutured were reconstructed by skin grafting. The survival and complications of flaps were observed in the scheduled postoperative follow-ups at outpatient visits, WeChat reviews and home visits, etc.Results:All 7 patients were successfully treated and had 12-24 months postoperative follow-up, with an average of 16 months. All flaps survived, with primary healing in 6 patients and 1 patient had partial flap necrosis with surface infection, which healed after dressing changes. The wound healing time was 14-36 days with an average of 17.9 days. The time for disconnection of the cross-leg vessel bridging pedicle was 3-4 weeks with the flap transfer, with an average of 3.6 weeks. The donor sites of ALTPFs and vessel pedicles all healed well. CDU confirmed the patency of the contralateral posterior tibial artery. Satisfactory functional recovery was achieved in the affected lower limb and there was a good function of the contralateral healthy lower leg.Conclusion:Application of the transfer of a free ALTPF with modified cross-leg vessel bridging in reconstruction of infected wounds with major vessel defects in the lower leg has shown excellent clinical outcomes. It is a practical and effective method in treatment of large infective defect in lower leg.

In order to improve the level of refined management of medical consumables, a hospital used radio frequency identification (RFID) technology to map the unique device identification barcode of medical devices to the supply-processing-distribution (SPD) code, generating a medical consumables RFID tag code with dual code carrier function and a unique serial number.

Objective To investigate the biomechanical effects of the medial protrusio technique on the acetabular cup in adult patients with developmental hip(DDH)after total hip arthroplasty.Methods The CT scanning data of bilateral hips from an adult patient with unilateral DDH were obtained further to develop a finite element model of the affected hemipelvis.The medial protrusio technique with various levels of medial protrusio was simulated,and the biomechanical differences between the medial protrusio and non-protrusio groups were evaluated.Results In the simulated pull-out test,the maximum anti-pull-out load strength of the non-protrusio group was 1 166 N.Compared with the non-protrusio group,the anti-pull-out load strength of the 4 mm and 8 mm medial protrusio groups increased by 45.8％and 57.1％,respectively.The peak micromotion at the cup-bone interface for the non-protrusio group was 166.4 μm in the standing phase of the gait cycle,and that of the 4 mm and 8 mm medial protrusio groups was decreased by 46.2％and 62.1％,respectively.Regarding the immediate stress distributions of periacetabular bone tissues following cup implantation,the differences between the groups were not significant.Under the loading condition of the standing phase,the non-protrusio group yielded the lowest average and peak stresses.The average stress increased with the level of medial protrusio,and the highest peak stress was observed in the 4 mm medial protrusio group.Conclusions The medial protrusio technique can improve the initial stability of the acetabular cup,and the initial stability is positively proportional to the protrusio level.However,owing to the concentration of marginal stress at the cup-bone interface,a minor medial protrusio cup with insufficient bone coverage might increase the risk of various prosthesis-related complications.
