Objective:To retrospectively analyze the anesthetic management characteristics of children undergoing resection of pheochromocytoma and paraganglioma (PPGL).Methods:The clinical data from patients undergoing resection of PPGL and confirmed histologically from January 1, 2010 to June 30, 2023 were retrospectively collected. The baseline characteristics, intraoperative conditions and postoperative complications were recorded.Results:The clinical data from 47 pediatric patients were analyzed. The overall incidence of hemodynamic instability events was 68% (32 cases). Lowering preoperative blood pressure to normal levels and the maximum diameter of tumor≥6 cm was helpful in reducing the incidence of the intraoperative hemodynamic instability events ( P<0.05). Postoperative hypotension developed in 7 cases, acute left heart failure in 1 case, arrhythmia in 1 case, adrenocortical insufficiency in 4 cases, and pulmonary infection in 13 cases. Conclusions:Thorough preoperative preparation, evidence-based anesthetic management, and meticulous postoperative vital sign monitoring can increase the perioperative safety for children undergoing resection of PPGL, thereby reducing the incidence of complications.

ObjectiveTo investigate the impact of acute respiratory infections in children under 12 years old in Pudong New Area， Shanghai from 2019 to 2023. MethodsAcute respiratory infection samples of children under 12 years old from three sentinel hospitals in Pudong New Area， Shanghai from 2019 to 2023 were collected， and 42 respiratory infection pathogens， including influenza virus， adenovirus， parainfluenza virus， respiratory syncytial virus， human enterovirus/rhinovirus， human pulmonary virus， human bokavirus， coronavirus （229E， HKU1， NL63 and OC43）， and novel coronavirus， were detected with microfluidic chips. The situation of acute respiratory infections among outpatient and inpatient children in this area was analyzed for the before the implementation of non pharmacological intervention measures （2019.12‒2020.1）， during the period of non pharmacological intervention measures （2020.2‒2022.12）， and after non pharmacological intervention measures （2023.1‒2023.6）. ResultsFrom 2019 to 2023， a total of 1 770 samples were collected， and 445 pathogens were detected， with a detection rate of 25.14% （445/1 770）. The main pathogens detected during the study period were influenza virus： 8.70% （154/1 770）， respiratory syncytial virus： 4.41% （78/1 770）， human enterovirus/rhinovirus： 2.66% （47/1 770）， human adenovirus： 2.49% （44/1 770）， and parainfluenza virus： 2.20% （39/1 770）. Before the implementation of non pharmacological intervention measures， outpatients were primarily infected with influenza， parainfluenza virus， and respiratory syncytial virus， with detection rates of 8.09%， 4.49%， and 4.04%， respectively； inpatients were mainly infected with influenza， respiratory syncytial virus， and parainfluenza virus， with detection rates of 4.49%， 3.82%， and 3.15%， respectively. During the period of non pharmacological intervention measures， influenza， rhinovirus and respiratory syncytial virus were the main viruses detected in the samples of outpatient children， with detection rates of 4.04%， 3.60%， and 2.47%， respectively； inpatient samples mainly detected respiratory syncytial virus， rhinovirus， and influenza virus， with detection rates of 3.60%， 2.02%， and 1.80%， respectively. After non pharmacological intervention measures， influenza， rhinovirus and respiratory syncytial virus were the main pathogens detected in the outpatients， with detection rates of 9.89%， 2.92% and 2.02%， respectively； influenza， respiratory syncytial virus， and rhinovirus were the main pathogens detected in inpatient children， with detection rates of 6.29%， 1.57%， and 1.35%， respectively. ConclusionThe prevalence of pathogens related to acute respiratory infections in children is influenced by non pharmacological preventive measures.

Pulmonary sarcomatoid carcinoma(PSC)is a rare and highly malignant tumor,which includes the follow-ing five pathologic types:pleomorphic carcinoma,spindle cell carcinoma,giant cell carcinoma,carcinosarcoma and pulmonary blastoma.The onset of PSC is occult with non-specific clinical symptoms and signs.The clinical manifestations include irritat-ing cough,bloody sputum,dyspnea,chest pain and so on,which are closely related to the growth and invasion site of the tumor.PSC tends to metastasize early,so most patients are already in local advanced stage or advanced stage with a median survival of 9 months at the time of hospital visit.A patient with primary PSC which led to 90%stenosis in central airway was treated by com-bined method of vascular and tracheoscopic intervention in our respiratory center.This treatment prolonged the patient's survival time and got a satisfactory effect at 19-month follow-up after surgery.Herein we report the case for clinical reference.

Background and objective As a new technique developed in recent years,bronchoscopic interven-tion therapy has the advantages of minimal invasion,high safety and repeatability.The aim of this study is to investigate the clinical characteristics of bronchopleural fistula(BPF)induced by surgeries for lung malignancies or benign diseases and the effect of bronchoscopic intervention therapy for BPF,so as to provide support for prevention and treatment of BPF.Methods Data 64 patients with BPF who were treated by bronchoscopic intervention in Respiratory Disease Cen-ter of Dongzhimen Hospital,Beijing University of Chinese Medicine from June 2020 to September 2023 were collected.Patients with fistula diameter ≤5 mm were underwent submucous injection of macrogol,combined with blocking therapy with N-butyl cyanoacrylate,medical bioprotein glue or silicone prosthesis.Patients with fistula diameter＞5 mm were im-planted with different stents and cardiac occluders.Locations and characteristics of fistulas were summarized,meanwhile,data including Karnofsky performance status(KPS),shortbreath scale(SS),body temperature,pleural drainage volume and white blood cell count before and after operation were observed.Results For all 64 patients,96 anatomic lung resections in-cluding pneumonectomy,lobectomy and segmentectomy were executed and 74 fistulas occurred in 65 fistula locations.The proportion of fistula in the right lung(63.5％)was significantly higher than that in the left(36.5％).Besides,the right inferior lobar bronchial fistula was the most common(40.5％).After operation,KPS was significantly increased,while SS,body tem-perature,pleural drainage volume and white blood cell count were significantly decreased compared to the preoperative values(P＜0.05).By telephone follow-up or readmission during 1 month to 38 months after treament,median survival time was 21 months.33 patients(51.6％)showed complete response,7 patients(10.9％)showed complete clinical response,18 patients(28.1％)showed partial response,and 6 patients(9.4％)showed no response.As a whole,the total effective rate of broncho-scopic intervention for BPF was 90.6％.Conclusion BPF induced by pulmonary surgery can lead to severe symptoms and it is usually life-threating.Bronchoscopic intervention therapy is one of the fast and effective therapeutic methods for BPF.

Pulmonary mixed squamous cell and glandular papilloma(MSCGP)is a subtype of pulmonary papil-loma,which can be classified as central type and peripheral type based on its site of development.The central type is the most common.The clinical manifestations of pulmonary MSCGP are mainly related to the location of the tumor.Surgery is the main treatment for this disease.Bronchoscopic interventional treatment for the MSCGP in the central trachea could receive satis-factory effect.We reported a patient suffered from diffuse tracheal MSCGP who was treated by bronchoscopic interventional treatment in Respiratory Disease Center,Dongzhimen Hospital of Beijing University of Chinese Medicine,aiming to enhance the recognition of the clinical features and provide clinical references for the diagnosis and treatment of such disease.

Objective To observe the improvement of motor dysfunction and serum levels of C-reactive protein(CRP),blood glucose and blood lipid in post-stroke patients treated with scalp acupuncture at different needle retention time.Methods A total of 120 patients with motor dysfunction after stroke were randomly divided into control group,observation group 1 and observation group 2,with 40 cases in each group.The patients in the 3 groups were treated with scalp acupuncture,body acupuncture and routine rehabilitation exercise,once a day and 6 times a week,lasting for 2 weeks.The control group was given scalp acupuncture with retaining of needles for 30 minutes,the observation group 1 was given scalp acupuncture with retaining of needles for one hour,and the observation group 2 was given scalp acupuncture with retaining of needles for 2 hours.Before and after treatment,the 3 groups were observed in the changes of the scale scores of National Institutes of Health Stroke Scale(NIHSS),Fugl-Meyer Assessment(FM A),Berg Balance Scale(BBS)and modified Barthel Index(MBI),and the levels of laboratory indicators of peripheral blood CRP,fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C).After treatment,the clinical safety of the three groups was evaluated.Results(1)After treatment,the scale scores of NIHSS in the three groups were lower(P＜0.01)and the scale scores FMA,BBS and MBI were higher than those before treatment(P＜0.05 or P＜0.01).The comparison of post-treatment scale scores showed that the differences among the three groups were statistically significant(P＜0.01).The intergroup comparison showed that the decrease of NIHSS score and the increase of FMA,BBS and MBI scores in the observation group 2 were significantly superior to those in the control group and the observation group 1(P＜0.01);the improvement of FMA score in the observation group 1 was significantly superior to that in the control group(P＜0.01),while the improvement of NIHSS,BBS and MBI scores tended to be superior to that in the control group without statistically significant differences(P＞0.05).The results indicated that the curative effect of scalp acupuncture plus exercise regimen was positively correlated with the duration of needle retention for scalp acupuncture.(2)After treatment,the laboratory indicator levels of CRP and FPG in the peripheral blood of the three groups,the levels of TG and LDL-C in the two observation groups and the level of HDL-C in the observation group 2 were improved compared with those before treatment(P＜0.05 or P＜0.01).Statistically significant differences were presented in the post-treatment levels of CRP and TG in peripheral blood among the three groups(P＜0.05 or P＜0.01).The intergroup comparison showed that the improvement of CRP and TG levels in the observation group 2 was significantly superior to that in the control group,and the improvement of CRP level in the observation group 2 was significantly superior to that in the observation group 1,the differences being statistically significant(P＜0.05 or P＜0.01).The TC level in the three groups after treatment did not differ from that before treatment,and there was no significant difference in TC level after treatment among the three groups either(P＞0.05).(3)During the treatment,no adverse reactions such as fainting,needle breaking and hematoma occurred in the three groups,the vital signs of the patients were stable,and there were no obvious abnormal changes in pulse,blood pressure and respiratory rate.Conclusion Scalp acupuncture can effectively improve the motor function of post-stroke patients in a pasitive time-effect relationship with the needle retention,and better the curative effect can be achieved by retaining of the needle for 2 h.

General education in biological courses such as "Principal Biology" is an essential avenue for gaining an understanding of life science and developing an interest in the field. The reform of biological education teaching mode based on interdisciplinary approaches aims to foster cross-disciplinary talents, which is crucial for the rapid development of China's bioeconomy. Teaching method that simply superimposes different subjects is difficult to discover the value of interdisciplinary education. To address this, a novel teaching system and an innovative teaching mode were proposed for "Principal Biology" course by integrating science and engineering subjects, based on the cross-disciplinary feature in Beijing Institute of Technology. The system involves the design of cross-disciplinary course content and the integration of multiple disciplines and knowledge points based on students' majors, taking into account the characteristics of students' physical and mental development. To improve students' scientific literacy and interdisciplinary thinking ability, differentiated and major-driven teaching modes were applied by incorporating the "1+N" mixed and immersive cross-thinking training. The effectiveness of tailored cross-disciplinary teaching was evaluated using "in-teaching" and "post-teaching" data feedback models, which promote the optimization of teaching process and enhance the quality of education in cross-disciplinary biological science.
