Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals"， it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure， qi and liquid imbalance， and kidney collaterals impairment， and it is proposed that the treatment principle is to nourish the sweat pore， regulate qi and fluid， and supplement the kidney and unblock the collaterals. In clinic， guided by sequential therapy and according to the different disease mechanism characteristics of the four stages， including early stage of the disease， hormone induction stage， hormone reduction stage， hormone maintenance stage， the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency， modified Zhenwu Decoction （真武汤） was applied to warm yang and drain water； for hormone induction stage with yin deficiency resulting in effulgent fire， modified Zhibai Dihuang Pill （知柏地黄丸） plus Erzhi Pill （二至丸） was used to enrich yin and reduce fire； for hormone reduction stage with qi and yin deficiency， modified Shenqi Dihuang Decoction （参芪地黄汤） was used to boost qi and nourish yin； for hormone maintenance stage， modified Shenqi Pill （肾气丸） was used to supplement yin and yang. Meanwhile， the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals， so as to providing ideas for clinical treatment.

Objective The clinical characteristics of 21 cases of nocardiosis were reviewed and antimicrobial resistance of Nocardia strains was analyzed in order to improve the accuracy of clinical diagnosis and treatment of nocardiosis.Methods Clinical data of patients diagnosed with nocardiosis in Zhoukou Central Hospital from 2019-2023 and the corresponding results of antimicrobial susceptibility testing were retrospectively analyzed to summarize the clinical characteristics and outcomes of patients.Results Overall,the 21 cases of nocardiosis included 9 males and 12 females,aged 2-91 years.Underlying disease was reported in 15 patients.Most common type of nocardiosis was pulmonary nocardiosis in 15 cases,followed by skin and soft tissue infection,pleurisy,lymphadenitis,and disseminated nocardiosis.Laboratory tests showed increased levels of WBC,neutrophils percentage,erythrocyte sedimentation rate,C-reactive protein,and procalcitonin.The 21 strains of Nocardia included 4 strains of Nocardia cyriacigeorgica,2 strains each of Nocardia brasiliensis,Nocardia abscessus,Nocardia asiatica,Nocardia otitidiscaviarum and Nocardia beijingensis,and 1 strain each of Nocardia puris,Nocardia asteroides,Nocardia farcinica,Nocardia pneumoniae,Nocardia amamiensis,and 2 strains of unclassified Nocardia.All of the Nocardia strains(100％)were susceptible to linezolid,amikacin,and trimethoprim-sulfamethoxazole,followed by various levels of susceptibility to cefotaxime,moxifloxacin,imipenem and ceftriaxone,and lower susceptibility rate to cefepime,minocycline,ciprofloxacin and clarithromycin.Antimicrobial susceptibility of Nocardia strains varied with different Nocardia species.Of the 21 patients,two were referred to other hospitals,another two died,two patients received unknown treatment,and the remaining 15 patients were improved after antibiotic treatment,including sulfonamides combined with other antibiotics in 11 cases,other antibiotics in 4 cases.Conclusions Immunocompromised patients or those with underlying diseases are more susceptible to nocardiosis.The clinical features are complex and diverse.Antimicrobial susceptibility of Nocardia strains varied with different Nocardia species.Accurate identification and antimicrobial susceptibility test are essential for prescribing effective antibiotic treatment.

Objective To investigate the distribution characteristics of Klebsiella pneumoniae(KP),hyperviru-lent Klebsiella pneumoniae(hvKP),carbapenem-resistant Klebsiella pneumoniae(CRKP),and hypervirulent car-bapenem-resistant Klebsiella pneumoniae(hv-CRKP/CR-hvKP)in the environment of general intensive care unit(ICU)at medical institutions,and provide reference for environment assessment as well as healthcare-associated in-fection(HAI)prevention and control in ICU.Methods A total of 3 336 environmental specimens were collected from general ICUs of medical institutions in Shanghai in 2019 and 2023.After strain isolation,antimicrobial suscep-tibility testing and whole genome sequencing were conducted.Results The detection rate of KP was 1.59％(n=53),among which hvKP,CRKP,and hv-CRKP/CR-hvKP accounted for 37.74％(20/53),52.83％(28/53),and 24.53％(13/53)of the total detected strains,respectively.The main types of hvKP were ST11-KL64 and ST11-KL25,CRKP were ST15-KL19 and ST11-KL25,hv-CRKP/CR-hvKP were ST11-KL25 and ST11-KL64.The main carried resistance genes included fosA,oqx AB,tet(A),blaTEM-1B,blaKPC-2,qnrS11,etc.All strains carried viru-lence genes fimH,iutA,ent A,entB,entC,entD,entE,and entF,with only one strain carrying rmp A gene.Conclusion KP contamination is widespread in general ICU environment of medical institutions,predominantly ST11 and ST15,presenting a polymorphic distribution.CRKP and hvKP account for a relatively high proportion,and multidrug resistance is serious.Co-evolution of drug resistance and virulence presents in KP,and poses signifi-cant infection and pathogenic risks to patients,necessitating enhanced clinical vigilance and preparedness for poten-tial outbreaks.

In this study, we proposed an idea on systematic construction and optimization of a clinical coaching teacher qualification access system in Peking University Third Hospital by combining lean thinking and the Six Sigma methodology and following the steps of definition, measurement, analysis, improvement, and control. Based on the constructivism theory, the clinical coaching teacher qualification access system is divided into two progressive sessions: access to clinical coaching qualifications and access to theoretical teaching qualifications. By analyzing the appraisal data of clinical coaching teacher qualification access in the past 10 years, we revealed the data characteristics of pass rates of clinical coaching qualifications to determine the goal for dynamic improvement. On top of this analysis, we identified measures to maintain a stable pass rate of clinical coaching teacher qualification access, optimized the development direction and path of the clinical coaching teacher qualification access, and continuously promoted the teaching ability of teachers through the coordinated implementation of different systems and measures. In our research, we expanded the administrative scope of the access system, sorted out the objectives and paths of the system improvement, and provided a practical reference for constructing a clinical coaching teacher qualification access system and promoting the construction of teaching quality standardization in university-affiliated hospitals.

Objective:To construct an intelligent APP-assisted process assessment mode for standardized residency training and explore its application effect.Methods:Based on the "XUEYIKU" APP platform developed in Peking University Third Hospital, we built a standardized process of process assessment for standardized residency training assisted by intelligent APP and combining both online and offline components. We analyzed the frequency of APP use, satisfaction with the APP, the problems solved by the APP, and the aspects that need to be improved. SPSS 26.0 was used for t-test and Chi-square test. Results:The satisfaction score of teachers with the APP was (7.66±1.86) points. The satisfaction score of professional base teaching directors/process assessment coordinators was higher than that of clinical teachers [(8.28±1.30) vs. (7.42±1.99), P=0.013]. Most residents were satisfied with the APP (67.44%, 29/43), regarded its role in supporting the entire assessment process as important (55.81%, 24/43), and reviewed teacher feedback (65.12%, 28/43). Some teachers indicated that the APP solved problems such as paperless exam scoring (59.00%, 59/100), standardized exam processes (43.00%, 43/100), score statistics (42.00%, 42/100), and score reporting (42.00%, 42/100). The residents believed that the APP resolved issues such as exam notification (44.19%, 19/43), scheduling (41.86%, 18/43), and result feedback (41.86%, 18/43). Both teachers and residents mentioned the need for further strengthening the stability of the APP system and simplifying operational steps. Conclusions:With APP as a link, through the instant transmission and feedback of data, the intelligent APP-assisted process assessment mode drives the reflection and summarization of professional bases, clinical teachers, and residents, and promotes the post competence of residents.

Sinusitis is a prevalent nasal disease in children, characterized by chronic and difficult-to-treat symptoms. Its onset is related to nasal stagnation, gallbladder and lung dysfunctions. This article explores the root cause based on Huangdi Neijing by considering the physiological and pathological characteristics of children. The core pathogenesis of pediatric sinusitis is the transmission of heat from the gallbladder and lung to the brain and nose, disrupting normal nasal function. Wind and heat pathogens often persist, accumulate, and transform into turbid qi, which are common triggers of the disease. Evil qi retention and yin depletion are internal factors that cause the prolonged and unhealed condition of the disease. This article emphasizes individualized treatment approaches based on disease duration and the severity of pathogenic factors. If external pathogens remain uncleared, treatment should focus on dispelling wind, clearing heat, dispersing with pungent medicinals, and dredging nasal orifices. If internal fire is exuberant, clearing lung qi, inhibiting hyperactive liver yang, and clearing exuberant fire should be used to relieve stagnation. In chronic cases with residual pathogens and liver-kidney yin deficiency, nourishing yin, clearing fire, and moistening the nasal orifices are essential. When exuberant heat has subsided, but the symptom of a persistent runny nose continues, leading to the loss of healthy qi and damage to the lung and spleen, treatments that tonify the spleen, benefit the lung, and reinforce healthy qi should be adopted to relieve stagnation. These treatments aim to restore the balance of the body′s vital qi by addressing both the lingering symptoms and the underlying weakness of the lung and spleen. The diagnosis and treatment of pediatric sinusitis based on the theory of "the transmission of heat from gallbladder and lung" can help reduce the recurrence of sinusitis and alleviate symptoms, with the aim of broadening the approach of traditional Chinese medicine in treating this condition.

Objective:To compare the effects of standard cognitive behavioral therapy for insomnia (CBT-I) and enhanced cognitive behavioral therapy for insomnia(CBT-I Plus) in patients with chronic insomnia disorder comorbid anxiety or depressive symptoms.Methods:This prospective study included 148 patients with chronic insomnia disorder and anxiety/depression symptoms who were treated at the Sleep Disorder clinic of Shanghai Mental Health Center between July 2020 and August 2023. Participants (56 males, 92 females; aged 18-65 years, mean age 35.08±10.30 years) were randomly assigned in a 1∶2 ratio to the CBT-I group ( n=54) or CBT-I Plus group ( n=94). The CBT-I Plus group received additional treatments targeting anxiety and depressive symptoms. Treatment lasted 8 weeks, with assessment conducted at baseline, weeks 2, 4, and 8. Depression severity was measured using the 17-item Hamilton Depression Rating Scale (HAMD 17), anxiety severity with the Hamilton Anxiety Scale (HAMA), and sleep quality with the Pittsburgh Sleep Quality Index (PSQI). Paired sample t-tests were used to evaluate within-group changes, repeated-measures ANOVA compared treatment effects between groups, and ANCOVA was employed to adjust for confounding variables. Results:Significant reductions in PSQI, HAMD 17, and HAMA scores were observed in both groups after treatment: CBT-I group: PSQI ((14.15±2.54) vs. (7.50±3.35), t=13.25), HAMD 17 ((14.70±4.09) vs. (7.40±4.61), t=9.33), and HAMA ((14.94±4.11) vs. (5.56±3.67), t=12.38) (all P<0.001).CBT-I Plus group: PSQI ((14.87±3.01) vs. (7.19±3.86), t=18.75), HAMD 17 ((16.84±3.91) vs. (6.84±4.79), t=17.42), and HAMA ((15.57±3.93) vs. (6.10±4.57), t=18.39) (all P<0.001). After adjusting for HAMD 17 scores and medication use, no statistically significant between-group differences were observed in changes in PSQI, HAMD 17, and HAMA scores ( P>0.05). A significant time-by-group interaction was found for the PSQI daytime dysfunction subscale ( F=4.87, P<0.01). Conclusion:Both CBT-I and CBT-I Plus improve sleep and emotional symptoms in patients with chronic insomnia disorder and comorbid anxiety/depression symptoms. However, CBT-I Plus has no significant advantages over standard CBT-I. Further studies are needed to refine the timing and content of interventions.

Objective To find potential effect of Ginkgo biloba extract on proliferation and migration of human gli-oma cell line.Methods Glioma cell line U87 was cultured and incubated with Ginkgo biloba extract at doses of 0,10,50,and 100 μg/mL,respectively.The proliferation activity of the cells in each group was detected by 5-ethynyl-2'-deoxyuridine(EDU)experiment,the migration activity of the cells in each group was examined by scratch experiment,the invasion activity of the cells in each group was detected by Transwell experiment and the expression of epithelial-mesenchymal transition(EMT)-related proteins,phosphatidylinositol-3-kinase(PI3K)/protein kinase B(AKT)signaling pathway proteins and E2F transcription factor 1(E2F1)protein in each group of the cells were detected by Western blot.Reply experiment was added with PI3K/AKT pathway activator 740 Y-P.Results Ginkgo biloba extract at concentrations of 10,50,and 100 μg/mL significantly inhibited the proliferation,migration,and invasion of U87 cells(P＜0.05).The protein level of vimentin,N-cadherin,p-PI3K,p-AKT and E2F1 was significantly decreased(P＜0.05),while the protein level of E-cadherin and ZO-1 was significantly increased(P＜0.05).After addition of 740 Y-P into the cultural system,the inhibitory effect of Ginkgo biloba extract on the proliferation and metastasis of U87 cells was inhibited and the protein level of vimentin,N-cadherin,p-PI3K,p-AKT,and E2F1 increased(P＜0.05),while the protein level of E-cadherin and ZO-1 was decreased(P＜0.05).Conclusions Ginkgo biloba extract may inhibit proliferation,migration and EMT of U87 cells,which is potentially related to the PI3K/AKT/E2F1 pathway.

Objective:To analyze the safety and short-term efficacy of thoracic radiotherapy combined with anlotinib in the treatment of inoperable non-small cell lung cancer (NSCLC).Methods:A prospective study was conducted on patients with unresectable locally advanced NSCLC who were intolerant to concurrent chemoradiotherapy and treated at the Department of Radiation Oncology, Cancer Hospital, Chinese Academy of Medical Sciences, from October 2020 to September 2023. Anlotinib was administered orally concurrently with radiotherapy (days 1-14, 21 days per cycle, for 3 cycles). Adverse effects and short-term tumor recurrence were observed from the beginning of radiotherapy to the 3-month post-radiotherapy. Kaplan-Meier method was used to calculate progression-free survival (PFS) and overall survival (OS) rates from the date of initial treatment (induction therapy), and intergroup comparisons were performed using the log-rank test.Results:The median age was 62 years (range:42-76 years), with a male predominance ( n=36, 88%) of the included 41 patients. The incidence of grade 3-4 acute hematologic adverse events was 20% (8 cases); the incidence of grade 3 hemoptysis was 2% (1 case), with no grade 4 hemoptysis; the incidence of grade 3-4 radiation pneumonitis was 10% (4 cases). No grade 5 adverse events were observed in the entire cohort. With a median follow-up of 19.7 months (range: 7.1-50.1 months), 19 patients (46%) experienced recurrence, including 4 patients (10%) with local recurrence, 6 patients (15%) with regional lymph node recurrence, and 11 patients (27%) with distant metastases. The 1-year PFS rate was 78.3%. 8 patients (20%) died, including 3 patients died from COVID-19 infection during the follow-up period, 1 patient who died from hypostatic pneumonia due to prolonged bed rest after cerebral infarction, and 4 patients died from tumor-related causes. The 1-year OS rate was 78.0%. Conclusions:Thoracic radiotherapy combined with anlotinib demonstrates good safety, manageable adverse events, and favorable short-term efficacy in NSCNC patients intolerant to concurrent chemoradiotherapy.
