ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective:To study the correlation between adverse clinical outcomes and early postnatal weight loss(representing the results of fluid management) during hospitalization in extremely premature infants(EPIs).Methods:From January 2019 to March 2023, EPIs (gestational age (GA)<28 weeks) admitted to neonatal intensive care unit(NICU) of our hospital were retrospectively analyzed. According to weight loss (WL) within the first 3 d after birth, the infants were assigned into no-WL group, WL<6% group, WL 6%-10% group and WL>10% group. The following items were compared among the four groups: fluid intake within the first 7 d after birth, the incidences of hemodynamically significant patent ductus arteriosus (hsPDA), PDA requiring surgical ligation, duration of invasive mechanical ventilation, ≥stage II necrotizing enterocolitis(NEC), grade 3-4 intraventricular hemorrhage(IVH), moderate bronchopulmonary dysplasia (BPD), severe BPD, mortality rates and total length of hospital stay.Results:A total of 119 EPIs were enrolled, including 41 in no-WL group, 22 in WL<6% group, 31 in WL 6%-10% group and 25 in WL>10% group. Among the four groups, no significant differences existed in fluid intake on d1 and d5-d7 after birth ( P>0.05). WL 6%-10% and >10% groups had significantly lower fluid intake during d2-d4 than no-WL group ( P<0.05).On d4, WL 6%-10% and >10% groups had lower fluid intake than WL <6% and no-WL groups( P<0.05).WL 6%-10% and >10% groups showed lower incidences of hsPDA than no-WL group ( P<0.05).WL>10% group had lower incidences of ≥stage II NEC, moderate BPD, shorter duration of invasive mechanical ventilation and total hospital stay than no-WL group( P<0.05). No significant differences existed in the incidences of PDA requiring surgical ligation, grade 3-4 IVH, severe BPD and mortality rates among the four groups ( P>0.05). Conclusions:For EPIs, a certain degree of WL within the first 3 d after birth is beneficial to reduce the incidences of hsPDA, NEC, moderate BPD, duration of invasive mechanical ventilation and total hospital stay. Focusing on body weight is helpful for a more optimal fluid management strategy in the early postnatal period.

Objective To understand the current situation of quality management and implementation of risk-based quality management in clinical trial institutions.Methods In the form of questionnaires,Questionnaire Star was used to create the questionnaire,which was sent to clinical trial organisations in all provinces and cities to fill in through emails and institutional WeChat groups.Results The questionnaire results from 123 clinical trial institutions from 25 provinces were included for analysis.The quality management status was as follows:104(84.6%)institutions of the main quality management mode were the internal quality control by GCP department.On average,each institution had 3、4 full-time staff for quality management,with an average of 1 full-time staff to manage 16.8 projects and 10.9 specialties.In the last three years,65(52.8%)institutions conducted training for researchers 2-3 times/year.Ninety-five(77.2%)institutions had established a clinical trial funding allocation system.Forty-nine(39.2%)institutions had established GCP informatization management system and 44(35.2%)institutions had established risk-based quality management model.In the case of coordination between the clinical trial institution and the sponsor,47(41.2%)institutions did not not aware of the sponsor's/CRO's quality management plan in their collaboration with the sponsor.Conclusion The surveyed institutions have weaknesses,such as insufficient dedicated personnel for quality management,low utilization rate of GCP information systems.The collaborative capacity between clinical trial institutions and sponsors needs to be improved,and the implementation rate of risk-based quality management is also low.

Objective:To investigate the diagnostic method and value of echocardiography in screening right patent ductus arteriosus(PDA) of infants.Methods:This was a prospective study.Thirty-one infants with right PDA diagnosed by ultrasound and confirmed by prenatal ultrasonography, electronic computed tomography angiography, angiocardiography and/or surgery in Hebei Children′s Hospital from April 2014 to May 2022 were collected as research subjects, and the association of right ductus arteriosus with aortic arch anomalies and complex cardiac malformations were summarized. The diagnostic method and value of ultrasonic screening were summed up.Results:Of the 31 cases, 30 cases were correctly diagnosed by ultrasound and 1 case was misdiagnosed, who was a left aortic arch descending to the right, a crossover variation of the right and left pulmonary arteries, and a rightward displacement of the ductus arteriosus. Among these cases diagnosed correctly, 27 cases (including 24 cases with right aortic arch and 3 cases with left aortic arch) presented that ductus arteriosus was open and its ostium of pulmonary artery end was located in the proximal right pulmonary artery in views of parasternal short-axis view of great vessels at cardiac base with the combination of two dimensions and color Doppler flow imaging. Other 3 cases of right aortic arch were all single ventricle with transposition of the great artery. Due to the parallel relationship of the two great arteries, the standard parasternal short-axis view of great vessels could not be obtained, and the right ductus arteriosus was found in the high parasternal views.In all of the 27 cases with right aortic arch and right ductus arteriosus, high parasternal views showed that one end of the ductus arteriosus was connected to the right aortic arch isthmus and the other end was connected to the right pulmonary artery. In all of the 3 cases with left aortic arch and right ductus arteriosus, the high parasternal views showed that one end of the ductus arteriosus was connected to the right subclavian artery and the other end was connected to the right pulmonary artery. Among the 27 cases with right aortic arch, 16 cases were accompanied with mirror image branches, 9 cases of which had complex cardiac malformations; 10 cases were associated with aberrant left subclavian artery, 1 case of which had complex cardiac malformations; 1 case was with isolated left subclavian artery, and without complex cardiac malformations. All 3 cases of left aortic arch were accompanied with isolated right subclavian artery and none of them were associated with complex cardiac malformations. Clinical outcomes of 30 cases with right PDA: 14 cases underwent ductus arteriosus ligation due to thick ductus or other heart malformations. In other 16 cases, 4 cases were closed spontaneously, 9 cases had persistent small ductus arteriosus, and 3 cases were lost to follow-up.Conclusions:Right ductus arteriosus is mostly related to the right aortic arch, and those with mirror image branches are prone to complex cardiac malformations; cases of left aortic arch with right ductus arteriosus are tend to accompany isolated right subclavian artery. Ultrasound has an important application in the screening and diagnosis of right PDA.

ObjectiveTo study the effect of modified Erchentang on the expression of key molecules in the high mobility group Box 1 protein （HMGB1）/receptor for advanced glycation endproduct （RAGE）/nuclear factor-κB （NF-κB） signaling pathway in bronchioles of rats with chronic obstructive pulmonary disease （COPD）， to explore the mechanism of modified Erchentang against bronchiolar inflammation of COPD rats via HMGB1/RAGE/NF-κB signaling pathway. MethodSixty SD rats were randomly divided into normal group， model group， modified Erchentang low-， medium- and high-dose groups （5， 10， 20 g·kg^-1·d^-1） and ethyl pyruvate （HMGB1 inhibitor） group， with 10 in each group. The COPD rat model was prepared by cigarette smoke combined with tracheal injection of lipopolysaccharide （LPS）. After modeling， the modified Erchentang groups were given corresponding drugs （ig） and Ringer's solution （4 mL， ip）， while the EP group was treated with equal volume of normal saline （ig） and EP （0.04 g·kg^-1·d^-1， ip）. The normal group and the model group received equal volume of normal saline （ig） and Ringer's solution （ip） for 21 consecutive days. The contents of HMGB1， chemokine （C-X-C motif） ligand 1 （CXCL1）， CXCL2 and monocyte chemotactic protein-1 （MCP-1） in bronchoalveolar lavage fluid （BALF） were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA expressions of HMGB1， RAGE and NF-κB p65 were determined by Real-time polymerase chain reaction （Real-time PCR）， and the protein expressions of HMGB1， RAGE， p-NF-κB p65， and alpha-smooth muscle actin （α-SMA） in bronchioles tissue of rats were determined by immunohistochemistry （IHC）. ResultCompared with the conditions in the normal group， the forced vital capacity （FVC）， forced expiratory volume in the first second （FEV1） and FEV1/FVC in the model group were decreased （P<0.01） while the contents of HMGB1， CXCL1， CXCL2 and MCP-1 in BALF were increased （P<0.01）. And the model group presented higher mRNA expressions of HMGB1， RAGE and NF-κB p65 （P<0.01） and protein expressions of HMGB1， RAGE， p-NF-κB p65 and α-SMA （P<0.05， P<0.01） than the normal group. Compared with the model group， the modified Erchentang medium- and high-dose groups had increased FEV1/FVC （P<0.05， P<0.01）， lowered contents of HMGB1， CXCL1， CXCL2 and MCP-1 in BALF （P<0.05， P<0.05）， and reduced mRNA expressions of HMGB1， RAGE and NF-κB p65 （P<0.05， P<0.01） and protein expressions of HMGB1， RAGE， p-NF-κB p65 and α-SMA （P<0.05， P<0.01）. ConclusionModified Erchentang can resist bronchiolar inflammation of COPD rats. The mechanism may be related to down-regulating the mRNA expressiona of HMGB1 and RAGE， inhibiting the activity of NF-κB， and reducing the release of HMGB1， CXCL1， CXCL2 and MCP-1， thus suppressing the inflammatory injury and abnormal repair of bronchioles.

ObjectiveTo observe the effect of modified Erchentang on the expression of key molecules in the Jagged1/Notch1/Hes1 signaling pathway in lung tissues of rats with chronic obstructive pulmonary disease （COPD） and explore its anti-inflammatory effect and molecular mechanism on COPD through the Jagged1/Notch1/Hes1 signaling pathway. MethodSixty SD rats were randomly divided into normal group， model group， low-， medium-， and high-dose modified Erchentang groups （5， 10， 20 g·kg^-1）， and γ-secretase inhibitor DAPT group （0.02 g·kg^-1）， with 10 rats in each group. The COPD model was induced in rats by cigarette smoking combined with intratracheal instillation of lipopolysaccharide （LPS）. Rats were treated with corresponding drugs by gavage， while those in the normal group and the model group were treated with the same amount of normal saline by gavage. The serum levels of Notch1， soluble intercellular adhesion molecule-1 （sICAM-1）， activated leukocyte cell adhesion molecule （ALCAM）， and soluble vascular adhesion molecule-1 （sVCAM-1） were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression of Jagged1， Notch1， and Hes1 was detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The protein expression of Jagged1， Notch1， Notch1 intracellular domain （NICD1）， and Hes1 in lung tissues of rats was detected by immunohistochemistry （IHC）. ResultCompared with the normal group， the model group showed increased serum content of Notch1， sICAM-1， ALCAM， and sVCAM-1 （P<0.01）， increased mRNA expression of Jagged1， Notch1， and Hes1 in lung tissues （P<0.01）， and increased protein expression of Jagged1， Notch1， NICD1， and Hes1 （P<0.01）. Compared with the model group， the medium- and high-dose modified Erchentang groups and the DAPT group showed decreased serum content of Notch1， sICAM-1， ALCAM， and sVCAM-1 （P<0.05， P<0.05）， down-regulated mRNA expression of Jagged1， Notch1， and Hes1 （P<0.05， P<0.01）， and reduced protein expression of Jagged1， Notch1， NICD1， and Hes1（P<0.05， P<0.01）. ConclusionModified Erchentang may inhibit the inflammatory response in the lung of COPD rats， and its mechanism may be related to the resistance of inflammatory injury in the lung by decreasing the mRNA expression of Jagged1， Notch1， and Hes1 and inhibiting the release of Notch1， sICAM-1， ALCAM， and sVCAM-1.

ObjectiveTo investigate the molecular mechanism of the anti-inflammatory effect of Erchentang in the lung tissue of the rat model of chronic obstructive pulmonary disease （COPD） via the heparin-binding factor （Midkine）/transmembrane receptor protein （Notch2）/Hey1 signaling pathway. MethodSixty SD rats were randomized into normal group， model group， modified Erchentang （5， 10， 20 g·kg^-1·d^-1） groups， and Notch1 pathway inhibitor （γ-secretase inhibitor， DAPT， 0.02 g·kg^-1） group， with 10 rats in each group. The rat model of COPD was established by cigarette smoke combined with lipopolysaccharide （LPS）. After the modeling， the rats were administrated with corresponding drugs by gavage， and those in the normal and model groups were administrated with normal saline by gavage for 21 days. The levels of Midkine， cytokine-induced neutrophil chemoattractant-1 （CINC-1）， macrophage-derived chemokine （MDC）， chemokine ligand 5 （CXCL5）， neutrophil elastase （NE）， and nuclear factor-kappa B （NF-κB） p65 in bronchoalveolar lavage fluid （BALF） were determined by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and immunohistochemistry were respectively employed to determine the mRNA and protein levels of Midkine， Notch2， and Hey1 in the lung tissue. ResultCompared with the normal group， the modeling increased the levels of Midkine， CINC-1， MDC， CXCL5， NE， and NF-κB p65 in BALF （P<0.01） and up-regulated the mRNA and protein levels of Midkine， Notch2， and Hey1 in the lung tissue （P<0.01）. Compared with the model group， medium- and high-dose modified Erchentang and DAPT lowered the levels of Midkine， CINC-1， MDC， CXCL5， and NF-κB p65 in BALF （P<0.01） and down-regulated the mRNA levels of Midkine， Notch2， and Hey1 （P<0.01）. ConclusionModified Erchentang may inhibit the inflammation in COPD rats by down-regulating the expression of Midkine， Notch2， and Hey1 and reducing the content of Midkine， CINC-1， MDC， and CXCL5.

Objective:To explore the occurrence and influencing factors of paralytic ileus (PI) in patients with adolescent idiopathic scoliosis (AIS), so as to provide references and basis for the formulation of clinical nursing intervention measures.Methods:Using the convenient sampling method, a total of 93 AIS patients who were hospitalized in Spine Center of Peking Union Medical College Hospital from January 2019 to June 2020 were selected as the research objects. The general information, disease and operation related information of patients were collected, and the incidence of PI was recorded. Binomial Logistic regression was used to analyze the influencing factors of PI occurrence in AIS patients after surgery.Results:PI occurred in 41.9% (39/93) patients, and the incidence of anorexia, abdominal distention, nausea, vomiting and abdominal pain were 66.7% (26/39), 61.5% (24/39), 59.0% (23/39), 30.8% (12/39) and 20.5% (8/39), respectively. Binomial Logistic regression analysis showed that straight leg elevation exercise ( OR=3.582, P=0.023), postoperative first feeding time ( OR=1.209, P=0.027), proton pump inhibitors ( OR=6.820, P=0.002) and osteotomy ( OR=5.516, P=0.007) were the influencing factors of PI occurrence after AIS. Conclusions:The incidence of PI is higher in AIS patients after surgery and the accompanying symptoms are mainly anorexia, abdominal distension and nausea. Straight leg elevation exercise, time of first postoperative feeding, proton pump inhibitors and osteotomy are the influencing factors of postoperative PI in AIS patients.

Objective:To explore the application effect of family-centered health education on parents of patients with adolescent idiopathic scoliosis.Methods:From September 2015 to December 2018, parents of patients who were diagnosed with adolescent idiopathic scoliosis in the Department of Orthopedics of a Class Ⅲ Grade A hospital in Beijing were selected as the research objects by convenience sampling method. According to the order of admission time, they were divided into the control group with 71 cases and the observation group with 67 cases. Parents in the control group were given routine health education while parents in the observation group were given family-centered health education on basis of the control group. The Chinese version of the State-Trait Anxiety Inventory and the Family Management Measure Scale were used to assess anxiety status and disease management abilities of parents, respectively.Results:There was no statistically significant difference in anxiety level of parents between the two groups ( P> 0.05) . At 3 and 6 months after discharge, the scores of parental disease management ability in the observation group were (45.89±4.18) and (41.84±3.02) , which were higher than (42.43±5.28) and (40.25±4.20) in the control group. The differences were statistically significant ( P<0.05) . The scores of parental disease management difficulties in the observation group were (28.20±4.71) and (32.98±6.16) , which were lower than (33.75±6.42) and (36.97±5.60) of the control group. The differences were statistically significant ( P<0.05) . Conclusions:Family-centered health education can improve parental disease management abilities of patients with adolescent idiopathic scoliosis after discharge, which is worthy of clinical reference and application.
