摘要
Epigenetic pathways play a critical role in the initiation, progression, and metastasis of cancer. Over the past few decades, significant progress has been made in the development of targeted epigenetic modulators (e.g., inhibitors). However, epigenetic inhibitors have faced multiple challenges, including limited clinical efficacy, toxicities, lack of subtype selectivity, and drug resistance. As a result, the design of new epigenetic modulators (e.g., degraders) such as PROTACs, molecular glue, and hydrophobic tagging (HyT) degraders has garnered significant attention from both academia and pharmaceutical industry, and numerous epigenetic degraders have been discovered in the past decade. In this review, we aim to provide an in-depth illustration of new degrading strategies (2017-2023) targeting epigenetic proteins for cancer therapy, focusing on the rational design, pharmacodynamics, pharmacokinetics, clinical status, and crystal structure information of these degraders. Importantly, we also provide deep insights into the potential challenges and corresponding remedies of this approach to drug design and development. Overall, we hope this review will offer a better mechanistic understanding and serve as a useful guide for the development of emerging epigenetic-targeting degraders.

Objective:To analyze clinical characteristics of patients within 48 hours in pediatric intensive care unit（PICU）,and investigate causes and prognosis of extubation failure in reintubation children.Methods:A single-center retrospective study was conducted.Patients who were reintubated within 48 hours after extubation in PICU at Children's Hospital of Fudan University from January 1，2019 to December 31，2022 were retrospectively enrolled.Patients with unplanned extubation for various reasons which include re-intubation due to surgery and replacement of tracheal intubation were excluded.We analyzed the clinical characteristics，causes of extubation failure and prognosis.Main outcome measures included principal diagnosis，pediatric critical illness score（PCIS），the reason of intubation，the glasgow coma scale（GCS），the direct cause of reintubation，aeration time，hospitalization period，outcomes at PICU discharge and whether to extubate successfully.Results:During the study period，a total of 2 652 patients were extubated in PICU,and a total of 87 children were enrolled.Finally，63（72.4%）patients survived at PICU，nine（10.3%）patients died in hospital，and 15（17.2%）patients were discharged automatically.In the survival group，38（60.3%）patients were decannulated and 25（39.7%）patients underwent tracheotomy.The top three principal diagnosis in 87 cases were central nervous system disease[34（39.1%）cases]，lower airway disease[18（20.7%）cases] and sepsis[nine（10.3%）cases].Of the 87 children，28（32.2%）patients were reintubated due to central respiratory failure，21（24.1%）patients were reintubated due to lower airway disease，20（23.0%）patients were reintubated due to upper airway obstruction，14（16.1%）patients were reintubated due to cough weakness and/or swallowing disturbance，and four（4.6%）patients were reintubated for other reasons.In children with mechanical ventilation duration ≥7 days before first extubation，central nervous system diseases were the most common primary diseases，and it accounts for 55.6%.Central respiratory failure was the main direct cause of reintubation，accounting for 40.0%，and more patients(40.0%) had GCS scores＜8 before the first intubation.Compared with the successful decannulation group，the extubation failure group had the higher proportion of children with GCS＜8（32.7% vs.10.5%， P＜0.05），the longer median duration of mechanical ventilation before the first extubation[239（123，349）h vs.68.5（19，206）h， P＜0.05]and the longer median length of ICU stay[38（23，54）d vs.24（12，43）d， P＜0.05].After comparing the three groups including survival group，in-hospital death group and automatic discharge group，the PCIS score of the survival group was the highest，and the in-hospital death group was the lowest( P＜0.05). Conclusion:The rate of reintubation at 48 h after extubation in PICU is 3.3%.The immediate causes of reintubation mainly included central respiratory failure，lower airway disease，upper airway obstruction，cough weakness and/or dysphagia.The mortality rate of reintubation in critically ill children is high and the prognosis is poor.

Objective:To compare the characteristics of patients undergoing blood purification treatment in PICU of a children′s tertiary hospital during 8 years, so as to analyze the changes in the development of blood purification technology in children in East China.Methods:Patients who received blood purification treatment in PICU of Children′s Hospital of Fudan University from 2014 to 2021 were included and divided into two study periods: 2014-2017 and 2018-2021.The clinical characteristics and treatment parameters of patients were collected and analyzed.Results:A total of 1 029 patients were included in the study, of which 103 were combined with extracorporeal membrane oxygenation.The 28-day survival rate of 926 patients treated with pure blood purification was 55.7%.Among them, patients with younger age, lower body weight, using mechanical ventilation, using vasoactive drugs before blood purification, and patients with multiple organ dysfunction syndrome had a higher distribution in the death group than those in survival group( P<0.05). During 8 years, a total of 3 688 cases of blood purification were performed.The main mode was continuous veno-venous hemodiafiltration (CVVHDF) (68.6%), followed by therapeutic plasma exchange (TPE) (23.8%) and hemoperfusion (HP) (4.8%); the main indication was acute kidney injury (AKI) (29.3%), followed by severe inflammatory disease (26.2%) and acute liver failure (16.2%). Compared with 2014-2017, the number of blood purification treatments in 2018-2021 increased by 47.4%, and the survival rate of patients increased significantly (48.7% vs. 58.1%, P<0.05). The distribution of blood purification patterns and indications also changed( P<0.05). The proportions of TPE (20.5% vs. 26.0%) and HP (3.1% vs. 6.0%) increased, while the proportion of CVVHDF (71.9% vs. 66.4%) decreased significantly.The proportions of AKI (29.8% vs. 38.9%) and refractory immune diseases (8.4% vs. 15.2%) were significantly higher, while severe inflammatory diseases (29.2% vs. 24.2%) and acute liver failure (19.6% vs. 13.8%) had declined. Conclusion:From 2014 to 2021, the number of blood purifications performed in our center increased significantly.Although the distribution of indications and patterns have also changed significantly, the overall survival rate is significantly improved.However, standardized practice still needs to be strengthened.

Objective:To prospectively investigate the prevalence of heparin-induced thrombocytopenia (HIT) in critically ill children during extracorporeal membrane oxygenation(ECMO) and explore the clinical characteristics and prognosis of HIT during ECMO.Methods:A total of 22 critically ill children, who had received ECMO support for more than 96 hours in the Intensive Care Unit at the Children′s Hospital of Fudan University from March 2019 to December 2020, were enrolled.According to the 4T score and the heparin/platelet factor 4(PF4) antibody, children whose 4T scores were not less than 6 and heparin/ PF4 antibodies were positive, were classified into HIT group ( n=6), and non-HIT group ( n=16). The clinical outcomes and the incidence of thrombotic events were compared between two groups. Results:The incidence of HIT during ECMO in critically ill children was 27% in this study.The incidence of thrombosis in the ECMO circuit in the HIT group was higher (100% vs.63%, P=0.133), and the average time to the first thrombosis in ECMO circuit in the HIT group was shorter than that in the non-HIT group (3.70 d vs.5.44 d, P=0.06). During the first 14 days of ECMO, the proportion of children with thrombotic events no less than twice was higher in the HIT group (67% vs.19%, P=0.054). There was no significant difference regarding the survival rate at 28 days after ECMO withdrawal between two groups (33% vs.50%, P=0.664). Conclusion:The prevalence of HIT during ECMO in critically ill children is high.Thrombosis events tend to occur earlier and more extensively in children with HIT during ECMO.No significant effect of HIT on the survival rate of children during ECMO is found.Whether HIT has effect on the survival rate of children with ECMO requires a prospective and large clinical study.
摘要
Objective:To explore the effects of external diaphragm electrical stimulation on the diaphragm thickness and function in mechanically ventilated children.Methods:A randomized controlled trial was conducted in children who were admitted to PICU at Children′s Hospital of Fudan University and received mechanical ventilation between June 2021 and April 2022.The control group was given the routine treatment of mechanical ventilation, and the intervention group was given external diaphragm electrical stimulation in the early stage of mechanical ventilation in addition to routine treatment.Diaphragm thickness was continuously measured by bedside ultrasound every day for one week after mechanical ventilation, and the changing trend of diaphragm thickness was observed, and the diaphragmatic thickening fraction (DTf) and the incidence of ventilator-induced diaphragmtic dysfunction(VIDD) were calculated at the same time.Results:A total of 32 valid samples were included, including 15 cases in intervention group (10 males) and 17 cases in control group (11 males). The median age of the patients was 33 (10, 77) months, and the median duration of mechanical ventilation was 12 (8, 21) days.The reasons for mechanical ventilation in children included respiratory insufficiency in ten cases, brain dysfunction in ten cases, heart failure in eight cases, and postoperative surgery in four cases.The diaphragm end-expiratory thickness (DTe) in intervention group and the control group showed a gradually decreasing trend from the 1st day to the 7th day.The left thickness was reduced by 11% on the 7th day compared to 1st day in intervention group, which was reduced by 18% in control group; the average daily DTe was reduced by 2% per day in intervention group and by 3% per day in control group.The trends on the right and left were similar.The DTe thickness in the intervention group was greater than that in control group, among which, the mean DTe thickness in the left side of the intervention group on the 7th day was (0.110 7±0.023 7)cm, which was greater than that in control group (0.093 5±0.016 9)cm, and the difference was statistically significant ( t=-2.372, P<0.05); On the second day, the mean DTe thickness on the right side in the intervention group was (0.1267±0.0277) cm, which was greater than that in control group (0.104 7±0.018 1)cm, and the difference was statistically significant ( t=-2.688, P<0.05). DTf in the intervention group was lower than that in control group at 7th day, but the difference was not statistically significant(left DTf: adjusted mean difference was -0.117, P=0.088; right DTf: adjusted mean difference was -0.065, P=0.277). The incidence of VIDD in the intervention group was lower than that in control group(33.3% vs.41.2%), but the difference was not statistically significant ( χ2=0.005, P=0.946). Conclusion:External diaphragmatic electrical stimulation may be helpful for alleviating diaphragmatic atrophy in mechanically ventilated children.However, whether the improvement of diaphragm atrophy is beneficial to clinical outcome still needs further study.
摘要
In recent years, the number of children with prolonged mechanical ventilation has increased rapidly, and they have been in intensive care units for a long time, resulting in a heavy disease burden and high mortality.Families and society are also paying more and more attention to this special group.The United States and Canada have issued a management consensus on mechanical ventilation for children at home, but the allocation of medical resources in China and other countries is very different, and the domestic family-centered management plan is still difficult at this stage.This review summarized the current status of long-term mechanical ventilation in children in China and other countries, and hoped to learn from foreign experience to help domestic children with long-term mechanical ventilation better.

Objective:To investigate the status of cognition and clinical management of prolonged mechanical ventilation(PMV) among medical staffs in pediatric intensive care unit(PICU) in China, and in order to improve the awareness of PICU medical staffs on PMV and standardize the management of PMV.Methods:The cross-sectional study was conducted with doctors and nurses in PICUs of the collaborative group as the survey objects from July 12 to September 12, 2020.The questionnaire was issued, collected and checked by the Children′s Hospital of Fudan University.Results:(1) PMV related settings: Nine out of eleven hospitals had established PMV multidisciplinary teams, respiratory techniques such as diaphragm ultrasound and airway peak flow monitoring could be respectively executed in 72.7% and 36.4% of PICU.Pulmonary rehabilitation techniques such as airway clearance techniques, induced spirometer exercise, external diaphragm pacemaker stimulation, transfer bed exercise, balloon blowing, hyperbaric oxygen therapy could be respectively executed in 100.0%, 9.1%, 9.1%, 9.1%, 27.3% and 27.3% of PICU, respectively.(2) The cognitive status quo of children′s PMV: The most medical staffs agreed with the view that PMV referred to the children′s continuous mechanical ventilation for more than two weeks.Sixty percent of medical staffs believed that children with PMV had basic central nervous system diseases, and 62.7% of medical staffs believed that the most common causes of difficulty in PMV weaning was abnormal brain function.(3) The cognitive status quo of the children′s PMV management in PICU: Respondents believed that the most commonly used mechanical ventilation mode was synchronized intermittent mandatory ventilation+ pressure support ventilation in children′s PMV during stable disease.Ninety-two percent of medical staffs performed the spontaneous breathing test when weaning.And 58.7% of the respondents agreed to perform tracheotomy for the children during 3 to 4 weeks of mechanical ventilation.More than half of medical staffs would execute diaphragm function assessment, bedside rehabilitation training, nutritional assessment, analgesia and sedation assessment for children with PMV.(4) The cognitive status quo of the children′s PMV management of transition from hospital to family: 54.5% of PICU provided family care training to the family members before the children were discharged from the hospital.One center established the PMV specialized outpatient clinic.45.5% of PICU would follow up these discharged children one month later.Conclusion:At present, PICU medical staffs have different awareness of children′s PMV related problems in China.And children′s PMV lacks a systematic plan regarding diagnosis, treatment and management.
摘要
Mechanical ventilation is becoming more and more common in clinical practice.It certainly helps patients to overcome the respiratory failure in children, but in the meantime, also lead to ventilator-induced diaphragm dysfunction(VIDD). VIDD is common in mechanical ventilation patients and are associated with prolonged duration of mechanical ventilation, difficult weaning, pulmonary infection and the mortality.With the development of clinical medical technology, more and more convenient devices are applied to monitor diaphragm function.This review expounded the latest monitoring technology and assessment indices of VIDD, including pressure-generating capacity, imaging examination and diaphragm electrical activity.

Objective:To explore the value of body temperature, pediatric clinical illness score(PCIS), white blood cell count (WBC), plasma C-reactive protein (CRP), procalcitonin (PCT) and pro-adrenomedullin (pro-ADM) in predicting nosocomial infection in PICU.Methods:From June 2016 to March 2017, the critically ill children in PICU of Children′s Hospital of Fudan University were selected and divided into nosocomial infection group and non nosocomial infection group according to the diagnostic criteria of nosocomial infection.The body temperature, PCIS, WBC, CRP, PCT and pro-ADM were recorded at 4 hours (T1), (48±1) hours (T2), (120±1) hours (T3) and (192±1) hours (T4) after admission, and their predictive value of each index, which was the closest time point (Th) to nosocomial infection was analyzed.Receiver-operating characteristic (ROC) curves were performed to calculate the areas under the curves (AUC), sensitivity and specificity, and multivariate Logistic regression analysis was used to study the risk factors of nosocomial infection.Results:A total of 85 cases were included, including 27 cases in nosocomial infection group and 58 cases in non nosocomial infection group.There was no significant difference in age, weight, body temperature, WBC, PCT, pro-ADM, primary disease and invasive operation between two groups (all P>0.05). There were significant differences in gender, PCIS, CRP, intubation rate and central venous catheterization rate ( P<0.05), when patients were admitted to PICU.At Th, the differences of body temperature, PCIS, CRP, PCT and pro-ADM between two groups were statistically significant ( P<0.05), as well as the AUC were 0.787, 0.755, 0.709, 0.704 and 0.809, respectively, as well as the best cut-off values for predicting nosocomial infection were 38.0 ℃, 87 points, 14.5 mg/L, 0.28 ng/mL and 0.67 nmol/L, respectively.There was no significant difference regarding WBC between two groups ( P>0.05). PCIS may be an independent risk factor for nosocomial infection( OR=0.978, 95% CI 95.9-99.9, P<0.05). Conclusion:Pro-ADM has high sensitivity and specificity in predicting nosocomial infection, and PCIS is an independent risk factor for nosocomial infection.

Objective:To investigate the correlation and consistency between the parameters of the thromboelastography(TEG) and of routine coagulation tests and platelet count(PLT) in critically ill children in the pediatric intensive care unit.Methods:We conducted a retrospective analysis on the results of the simultaneous TEGs, coagulation tests and PLT of 231 children in pediatric intensive care unit at Children′s Hospital Affiliated to Fudan University from March 2019 to July 2019, including the correlation analysis, the chi-square test and Kappa consistency analysis.Results:The reaction time(R) was linearly dependent on activated partial thromboplastin time(APTT), prothrombin time(PT) and thrombin time(TT), respectively.The maximal amplitude(MA), clot time formation(K) and alpha-angle(α) were linearly dependent on fibrinogen.The MA, K and α were linearly dependent on PLT, too.And the correlation between MA and PLT was the best( R=0.656). There were significant differences( P<0.001) and poor consistency(Kappa value: 0.112, 0.047, 0.124) between R and APTT, PT, TT.There was no significant difference( P>0.05) and there was moderate consistency(Kappa value: 0528, 0.518, 0.408) between Ma, K, α and PLT.There were significant differences( P<0.001) and the consistency was poor or fair(Kappa value: 0.324, 0.188, 0.170) between Ma, K, α and fibrinogen. Conclusion:TEG is significantly correlated with PLT in evaluating platelet function and the consistency is good.The TEG parameters are linearly correlated with the relevant results of routine coagulation tests in evaluating the coagulation factor and fibrinogen function, but consistency is weak.Therefore, it is concluded that these two methods are irreplaceable.

Objective:To develop the early respiratory rehabilitation techniques in pediatric intensive care unit(PICU) for children with mechanical ventilation.Methods:A respiratory rehabilitation team was established, and early respiratory rehabilitation intervention methods for critically ill children were also developed.Early bedside rehabilitation were implemented after the vital signs of mechanical ventilation children were stable for 24 hours, and the rehabilitation effect and adverse events were observed.Results:According to the patient′s condition, 23 patients in PICU received early respiratory rehabilitation after incubations, including 10 males and 13 females, aged 57.0(17.5, 91.5) months.There was no adverse event in 729 rehabilitation practices.The average consulting time was 8.0(4.0, 18.0) days after incubations.The average incubation time was 693.5(345.2, 1 027.1)hours of all the patients.As to 16 patients who were weaned before charged out, the average incubation time was 566.2(243.4, 928.7)hours, and the average incubation time from respiratory rehabilitation performance to weaning was 168.0(6.0, 564.0) hours.In 19 patients who only received limbs massage and passive movements, the average incubation time was 381.7(309.6, 541.4) hours and the average incubation time from respiratory rehabilitation performance to weaning was 187.2(81.5, 382.9) hours.However the difference between these who received respiratory rehabilitation and only received limbs massage and passive movements was not statistically significant.Conclusion:It′s safe and feasible to perform the early respiratory rehabilitation in PICU for critically ill children with mechanical ventilation.
