ObjectiveTo investigate the effect of video-based educational intervention combined with maternal presence on perioperative adverse outcomes in preschool children undergoing general anesthesia， including cooperation in anesthesia induction， perioperative anxiety， pain and agitation during recovery. MethodsA total of 300 preschool children scheduled for general anesthesia in our hospital from June to December 2023 were randomly assigned to control group （n=150） and intervention group （n=150）. The control group received routine recovery care. For the intervention group， in addition to routine recovery care， a preoperative visit was scheduled one day before surgery. During this visit， mothers were guided to watch anesthesia videos with their children. During the waiting period in the operating room and 30 minutes after awakening， the mothers were guided to accompany the children for more than 30 minutes. Recovery conditions were recorded using the surgical anesthesia information system， and the children’s anesthetic induction compliance， perioperative anxiety， pain， and agitation were evaluated and recorded using the modified Yale Preoperative Anxiety Scale （m-YPAS）， the Induction Compliance Scale （ICC）， the Children’s Pain Behavior Scale （FLACC）， and the Pediatric Agitation and Emergence Delirium Scale （PAED）. ResultsOn the preoperative visit day， there were no statistically significant differences in baseline data between the two groups （P > 0.05）. For perioperative anxiety， the m-YPAS scores of the intervention group were significantly lower than those of the control group， both when entering the operating room waiting area （35.27±6.48 vs. 41.79±6.68， P < 0.05） and 30 minutes after postoperative recovery （20.13±7.05 vs. 35.75±9.51， P < 0.05）. In terms of anesthesia induction cooperation， the ICC scores of the intervention group were significantly lower than those of the control group （1.84±0.95 vs. 3.17±0.62， P < 0.05）， and the proportion of good induction cooperation was significantly higher than that of the control group （24.00% vs. 12.67%， P < 0.05）. There was no significant difference in awakening duration between the two groups， but the intervention group had a significantly shorter length of stay in the post-anesthesia care unit than the control group （0.90±0.29 hours vs. 1.29±0.42 hours， P < 0.001）. For perioperative agitation， the PAED scores of the intervention group were significantly lower than those of the control group （entering in the operating room waiting area： 8.5 vs. 9.2， P < 0.05； 30 minutes after postoperative recovery： 4.2 vs. 7.8， P < 0.05）. In terms of pain scores， the FLACC scores of the intervention group were also significantly lower than those of the control group， both when entering the operating room waiting area （ 5.3 vs. 6.7， P < 0.05； 30 minutes after postoperative recovery： 2.1 vs. 4.9， P < 0.05）. ConclusionsVideo-based educational intervention combined with maternal presence reduces the perioperative anxiety， pain and agitation of preschool children undergoing general anesthesia， and improved the compliance of anesthesia induction. It is recommended to promote this intervention measure in clinical practice.

Background Previous research on chlorinated paraffins (CPs) in fine particulate matter (PM_2.5) has predominantly focused on short- and medium-chain chlorinated paraffins (SCCPs and MCCPs), and few studies could simultaneously determine short-, medium-, and long-chain chlorinated paraffins (LCCPs). Simultaneous extraction and determination of SCCPs, MCCPs, and LCCPs in PM_2.5 could provide technical support for their environmental monitoring and human health risk assessment. Objective To establish a method based on QUEChERS pretreatment method in conjunction with ultra-performance liquid chromatography-quadrupole/orbitrap high resolution mass spectrometry for simultaneously determining the levels of SCCPs, MCCPs, and LCCPs in PM_2.5. Methods The extraction solvents, extraction salts, and extraction steps of a QuEChERS method were optimized. The extraction efficiencies of the target substances were compared under 4 extraction solvents [acetonitrile, dichloromethane, and n-hexane solvents in sequence; acetonitrile: dichloromethane: n-hexane = 1: 1: 2 (v/v/v) mixed solvent; 1% acetic acid-acetonitrile: dichloromethane: n-hexane = 1: 1: 1 (v/v/v) mixed solvent; acetonitrile: dichloromethane: n-hexane = 1: 1: 1 (v/v/v) mixed solvent], 2 dehydrated salts (anhydrous MgSO₄+NaCl and anhydrous Na₂SO₄+NaCl), 2 purification salts (C18 and PSA), and 4 vortex time (5, 7.5, 10, and 12.5 min) conditions. Then internal standard was utilized to estimate linear range and detection limit of the refined QuEChERS approach. Results The linearities of SCCPs, MCCPs, and LCCPs were good in the range of 10~1000 ng·mL⁻¹ with the correlation coefficients all greater than 0.96. The method detection limits (MDLs) ranged from 0.01 to 0.29 ng·m⁻³. The spiked recoveries of SCCPs, MCCPs, and LCCPs at the low, medium, and high concentrations were 77.38%-81.64%, 93.11%-99.78%, and 87.41%-101.39%, respectively, and the relative standard deviations (RSDs) were 2.90%-12.84%. This method was used to determine the CPs levels in 11 PM_2.5 samples from Shijiazhuang. The positive rates of ∑SCCPs, ∑MCCPs, and ∑LCCPs were all 100%, the concentration ranges were 0.24-2.18 ng·m⁻³ (mean 0.84 ng·m⁻³), 0.17-1.67 ng·m⁻³ (mean 0.70 ng·m⁻³), and 0.01-0.16 ng·m⁻³ (mean 0.04 ng·m⁻³), respectively, and the percentages to ΣCPs were 52.95%, 44.39%, and 2.66%, respectively. Conclusion The method established in this study is simple, time-saving, solvent saving, and can simultaneously detect SCCPs, MCCPs, and LCCPs in PM_2.5, which is suitable for the determination of PM_2.5 samples in large quantities, and can also provide a reference for the detection methods of other halogenated organic compounds in PM_2.5.

OBJECTIVE To investigate the effect of salidroside (Sal) on bone loss in obstructive sleep apnea syndrome(OSAS) rats by regulating the osteoprotegerin(OPG)/receptor activator of nuclear factor kappa-B ligand(RANKL) pathway. METHODS Rats were randomly divided into(12 rats/group) control group,OSAS group,Sal-L,Sal-M,and Sal-H groups(17.5,35,70 mg/kg). Except for the control group,all other groups were used to replicate the OSAS rat model through hypoxia and reoxygenation cycles. Bone density meters,three-point bending experiments,and Micro CT were applied to measure the bone density,biomechanics,and microstructural changes of the femur in rats. ELISA method was applied to detect serum levels of osteocalcin(BGP),alkaline phosphatase(ALP),and cross-linked carboxy-terminal telopeptide of type Ⅰ collagen(CTX-I). RT-PCR was applied to detect OPG and RANKL mRNA levels in the femur. Western blotting was applied to detect the expression of OPG/RANKL pathway proteins in the femur. RESULTS Compared with the control group,the bone density,maximum intensity,maximum load,trabecular bone volume fraction(Tb.BV/TV),trabecular number(Tb.N),trabecular thickness(Tb.Th),BGP,ALP,OPG mRNA and protein expression,OPG/RANKL ratio of rats in the OSAS group were decreased,the mRNA and protein expression of CTX-I and RANKL were increased(P<0.05). Compared with the OSAS group,the bone density,maximum intensity,maximum load,Tb.BV/TV,Tb.N,Tb.Th,BGP,ALP,OPG mRNA and protein expression,OPG/RANKL ratio of rats in the Sal-L,Sal-M,and Sal-H groups were increased sequentially,the mRNA and protein expression of CTX-I and RANKL were decreased sequentially,the above changes were most great in the Sal-H group(P<0.05). CONCLUSION Salidroside promotes bone formation and inhibits bone resorption by increasing OPG expression and decreasing RANKL expression,thereby reducing bone loss in OSAS rats.

Objective To investigate the current state of quality management on intravenous therapy in secondary and tertiary hospitals in China.This study aims to provide a reference for the development of relevant policies,promoting the professionalization,standardization,and homogenization of intravenous therapy.Methods By a convenience sampling method,intravenous therapy nursing managers from secondary and tertiary hospitals in 31 provinces,autonomous regions,and municipalities were selected as survey participants in November 2023.A self-designed questionnaire was used for the survey.Results A total of 2 129 questionnaires were collected,of which 1,926 were valid,resulting in a response rate of 90.47％.Among the 1926 hospitals,1 733(89.98％)had established quality evaluation standards for intravenous therapy,and 1 734(90.03％)conducted regular quality inspections for intravenous therapy or peripherally inserted central catheter(PICC)insertion and maintenance.Additionally,1 604 hospitals(83.28％)had established protocols for handling and reporting intravenous therapy or PICC-related complications,and 1 574 hospitals(81.72％)regularly collected and analyzed data related to intravenous therapy or PICC insertion and maintenance.Moreover,371 hospitals(19.26％)had implemented intravenous therapy information management systems.Regarding various types of intravenous therapy documents,the highest rate of document types was informed consent forms,with a compliance rate of over 80.00％,followed by insertion records and catheter maintenance records,respectively.The lowest rate was complication management records,with a compliance rate of less than 50.00％.For catheter maintenance protocols,the highest compliance rate was for maintenance procedures,at over 85.00％,followed by insertion procedures.Except for PICCs,the compliance rate for establishing catheter removal and complication management procedures for other types of catheters was less than 65.00％.In terms of quality management of intravenous therapy,there are significant differences between secondary and tertiary hospitals.Conclusion The quality evaluation standards for intravenous therapy are relatively comprehensive,but the informatization of intravenous therapy quality management is still underdeveloped.Furthermore,there is a need to further standardize the documentation and procedures related to intravenous therapy,and there are differences in the level of intravenous therapy management among hospitals of different levels.

Objective:To evaluate the application effect of the "group-based" teaching assistant (TA) guidance model in homogenized clinical skill training.Methods:A pilot study was conducted on the cardiopulmonary resuscitation training course, and 32 students majoring in clinical integrative Chinese and Western medicine (five-year program) who were admitted to Shanghai University of Traditional Chinese Medicine in 2018 were randomly divided into control group ( n = 16) and TA group ( n = 16). The control group received traditional teaching methods, and the TA group was further divided into subgroups A, B, C, and D, with four graduate TAs providing group-based teaching. The groups were compared in terms of their satisfaction and test scores. SPSS 25.0 was used for t-test and analysis of variance. Results:The satisfaction survey showed that compared with the control group, the TA group had significantly higher degree of satisfaction with the increased practical opportunities, clinical skill practical ability, learning effect, and overall satisfaction. The immediate test showed that there was no significant difference in test score between the TA group (85.19±2.93) points and the control group (82.75±4.52) points. The test 30 days later showed that the TA group (83.50±5.13) points had a significantly higher test score than the control group (74.68±3.87) points, and the control group had a significantly lower test score than that in the immediate test ( P <0.001); however, there was no significant difference in the TA group's score between the immediate test and the test 30 days later. Conclusion:The "group-based" TA guidance model has a good effect in homogenized clinical skill training, and has a stable long-term effect, with high student satisfaction.

Objective:To investigate the characteristics of renal disease spectrum in children aged 0-3 years old, and to evaluate the clinical value of renal biopsy in children aged 0-3 years old with renal diseases.Methods:It was a retrospective analysis study. The children aged 0-3 years old with kidney diseases receiving renal biopsy and having complete clinical data in Shanghai Children's Hospital from January 1, 2009 to December 31, 2020 were enrolled. The clinical and pathological data of the children were collected. The spectrum of renal diseases, clinical phenotype, renal pathology, and the relationship between renal pathology/genotype and clinical phenotype were analyzed.Results:A total of 117 children aged 0-3 years old with kidney diseases were enrolled in the study, accounting for 6.5% (117/1 790) of all children (0-18 years old) with renal biopsies during the same period. There were 77 males and 40 females. The age was (2.20±0.51) years old (5-35 months). All cases of renal biopsies in children aged 0-3 years old were successful without serious complications. Nephrotic syndrome was the common clinical phenotype of kidney diseases in children aged 0-3 years old (59.0%, 69/117), followed by hematuria and proteinuria (29.1%, 34/117). Primary glomerular disease (69.2%, 81/117) was the major clinical type of renal diseases, followed by hereditary kidney diseases (29.1%, 34/117), in which Alport syndrome was the main hereditary kidney disease (79.4%, 27/34). Renal pathological types of children aged 0-3 years old were mainly distributed in minimal change disease (30.8%, 36/117), followed by glomerular minor lesion (26.5%, 31/117), mesangial proliferative glomerulonephritis (15.4%, 18/117), and focal segmental glomerulosclerosis (10.3%, 12/117). Among 40 children aged 0-3 years old with hematuria with/without proteinuria, 25 cases were diagnosed as Alport syndrome by abnormal immunofluorescence of type IV collagen in renal tissues. Among the 28 children with kidney diseases who underwent genetic testing, 23 cases had gene mutations, mainly in COL4A5 gene (60.9%, 14/23), among which 4 children had gene mutations in 8 children with refractory nephrotic syndrome. Among the children aged 0-3 years old with clinical manifestations of hematuria, the proportion of gross hematuria in children diagnosed with Alport syndrome (59.3%, 16/27) was significantly higher than that in children without Alport syndrome (20.0%, 3/15, χ2=5.999, P=0.014). Conclusions:Primary glomerular disease is the principal type of kidney diseases in children aged 0-3 years old, followed by hereditary kidney disease. Attention should be paid to children aged 0-3 years old with gross hematuria. Renal biopsy in children aged 0-3 years old is safe and reliable, and it is an essential means for the diagnosis of renal diseases. Renal biopsy combined with gene testing can better understand the etiology of kidney diseases and guide treatment in children aged 0-3 years old.

Radiotherapy is widely used in the management of advanced colorectal cancer (CRC). However, the clinical efficacy is limited by the safe irradiated dose. Sensitizing tumor cells to radiotherapy via interrupting DNA repair is a promising approach to conquering the limitation. The BRCA1-BARD1 complex has been demonstrated to play a critical role in homologous recombination (HR) DSB repair, and its functions may be affected by HERC2 or BAP1. Accumulated evidence illustrates that the ubiquitination-deubiquitination balance is involved in these processes; however, the precise mechanism for the cross-talk among these proteins in HR repair following radiation hasn't been defined. Through activity-based profiling, we identified PT33 as an active entity for HR repair suppression. Subsequently, we revealed that BAP1 serves as a novel molecular target of PT33 via a CRISPR-based deubiquitinase screen. Mechanistically, pharmacological covalent inhibition of BAP1 with PT33 recruits HERC2 to compete with BARD1 for BRCA1 interaction, interrupting HR repair. Consequently, PT33 treatment can substantially enhance the sensitivity of CRC cells to radiotherapy in vitro and in vivo. Overall, these findings provide a mechanistic basis for PT33-induced HR suppression and may guide an effective strategy to improve therapeutic gain.

Objective : To analyze the expression and immune infiltration levels of the BMP7 gene ( BMP7) in e- sophageal squamous cell carcinoma(ESCC) ． Methods : Initially，in 274 cases of ESCC and 242 cases of normal tissues，the level of BMP7 was verified by immunohistochemistry ，and the relationship between the expression difference and the survival cycle and clinical pathological characteristics of patients with ESCC was explored，and BMP7 overexpression plasmid transfection of ESCC cells was established，and the effect of BMP7 on the biological behavior of ESCC cells was examined by CCK-8，Clone，and Transwell. Results : BMP7 expression in normal e- sophageal tissues was higher than that of ESCC(P＜0. 001) ，the expression level of BMP7 was correlated with the degree of differentiation of patients(P = 0. 006) and TNM staging(P ＜0. 001) ，and the survival of patients with high expression of BMP7 exceeded that of patients with low BMP7 (P = 0. 041) ，and the experiments of CCK-8 and Clone showed that the proliferation effect of cells in the overexpressed BMP7 group was lower than that of the control group．Transwell experiments confirmed that the cell invasion migration capacity of the overexpressed BMP7 group was less than that of the control one．The immune infiltration results showed that BMP7 was positively correlated with macrophages(P = 0. 008) and negatively correlated with γ-δT cells(P = 0. 028) ． Conclusion BMP7 is low in ESCC and associated with poor prognosis and immune infiltration levels in patients.
