ObjectiveTo explore the possible mechanism of action of Lifei Xiaoji Pill （理肺消积丸， LXP） in the treatment of non small cell lung cancer based on the Warburg effect and the USP47/BACH1 pathway. MethodsFifty C57BL/6 mice were randomly divided into five groups， model group， LXP group， inhibitor group， LXP + inhibitor group， and cisplatin group， with 10 mice in each group. A lung cancer mouse model was established by subcutaneously injecting Lewis cells. On the next day， the model group mice were given 0.2 ml of saline by gavage daily， the LXP group given 240 mg/（kg·d） of LXP solution once a day by gavage， the inhibitor group intraperitoneally injected with P22077 at a dose of 10 mg/（kg·d） every day， the LXP + inhibitor group given both LXP by gavage and P22077 by intraperitoneal injection once a day， and the cisplatin group received 0.5 mg/（kg·d） cisplatin intraperitoneally every other day. All treatments lasted for 14 days. On the day after the last dose， tumor weight and volume were measured， tumor histopathology was examined by HE staining， apoptosis in tumor tissues was detected by TUNEL staining， and proliferation cell nuclear antigen （PCNA） protein levels were detected by immunohistochemistry. Warburg effect indicators， including glucose concentration， lactate content， and adenosine triphosphate （ATP） production in tumor tissues， were measured. Western Blot and qRT-PCR were used to detect the protein and mRNA expression levels of USP47， BACH1， hexokinase 2 （HK2）， and glyceraldehyde 3-phosphate dehydrogenase （GAPDH）. ResultsCompared with the model group， all drug intervention groups showed reduced tumor weight and volume， improved tumor pathology， decreased PCNA positive rate， increased apoptosis rate， and reduced expression levels of USP47， BACH1， and HK2 proteins and mRNA （P＜0.05 or P＜0.01）. Except for lactate content in the cisplatin group， the glucose concentration in tumor tissues of other drug intervention groups increased， while lactate content and ATP production decreased （P＜0.05 or P＜0.01）. Compared with the LXP group， the LXP + inhibitor group showed more significant improvements in these indicators （P＜0.05 or P＜0.01）. Compared with the cisplatin group， the LXP + inhibitor group had lower mRNA expression of HK2 and GAPDH， and lower protein levels of USP47 and HK2 （P＜0.05 or P＜0.01）. Compared with the inhibitor group， the cisplatin group had higher HK2 protein levels， while the LXP + inhibitor group showed lower mRNA expression of BACH1， HK2， and GAPDH （P＜0.05 or P＜0.01）. ConclusionLXP significantly inhibits tumor growth in lung cancer mice， and its mechanism of action may be related to inhibiting the Warburg effect via the USP47/BACH1 pathway.

Objective:To investigate the value of 18F-FDG PET/CT imaging in the diagnosis of suspected autoimmune encephalitis (AE) in children with epilepsy and negative MRI. Methods:From May 2019 to August 2022, 94 suspected AE children (49 males, 45 females; age 1-15 years) with epilepsy and negative MRI who underwent brain 18F-FDG PET/CT imaging at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. All patients were divided into AE and non-AE groups based on clinical final diagnosis. The effectiveness of visual diagnosis was evaluated. The cortical lesion extent score (S), and SUV max, SUV mean and minimum of SUV (SUV min) of cortical lesions (L), basal ganglia (B) and thalamus (T) were measured and SUV ratios (SUVR) of L/B or L/T were obtained. Independent-sample t test or Mann-Whitney U test was used to analyze data. Binary logistic regression analysis was used to screen the diagnostic factors of AE, and a diagnostic model was established. The diagnostic efficiency was evaluated by ROC curve analysis and Delong test. Results:There were 53 cases in AE group and 41 cases in non-AE group. Based on visual analysis, the sensitivity, specificity and accuracy of 18F-FDG PET/CT for AE were 100%(53/53), 43.9%(18/41) and 75.5%(71/94), respectively. Differences of LSUV max, LSUV mean, LSUV min, L/BSUVR max, L/BSUVR mean, L/BSUVR min, L/TSUVR max, L/TSUVR mean, L/TSUVR min and S between AE and non-AE groups were statistically significant ( z=-6.74, t values: from -8.51 to -3.97, all P<0.001). ROC curve analysis showed that the AUC of L/BSUVR max was the highest (0.914) among visual analysis and semi-quantitative parameters. Logistic regression analysis showed that S (odds ratio ( OR)=11.40, 95% CI: 2.18-59.52, P=0.004), L/BSUVR max( OR=13.19, 95% CI: 2.11-82.51, P=0.006) and L/TSUVR max( OR=9.66, 95% CI: 1.57-59.55, P=0.015) were independent diagnostic factors for AE. Regression model was established: P=1/(1+ e - x), x=2.433×S+ 2.580×L/BSUVR max+ 2.267×L/TSUVR max-3.802. The AUC of this model was 0.948, with the sensitivity, specificity and accuracy of 98.1%(52/53), 90.2%(37/41) and 94.7%(89/94), respectively. The diagnostic efficacy of the optimized scoring system was consistent with the pre-optimization model, and were both superior to L/BSUVR max(both z=2.01, both P=0.040). Conclusion:The diagnostic model and scoring system based on the semi-quantitative analysis of 18F-FDG PET/CT have better diagnostic efficacy for AE and are superior to semi-quantitative parameters alone.

ObjectiveTo analyze the development status and quality of clinical practice guidelines for the treatment of dominant diseases with Chinese patent medicines （CPMs）. MethodsDatabases were searched from Jan. 2019 to Dec.2023 to collect the published clinical practice guidelines of CPMs for the treatment of dominant diseases. The information about the title， the participants， clinical problems， outcomes， evidence grade， recommendations， and recommendation strength in the included clinical practice guidelines were collected， for which the development status was analyzed， and the quality was evaluated with the Scientific， Transparent and Applicable Rankings （STAR） tool for clinical practice guidelines. ResultsTotally， 34 guidelines were included， involving 273 kinds of CPMs. One to ten （with the medium five） clinical problems were proposed from 29 clinical practice guidelines respectively. All the guidelines divided the evidence into four grades according to Grade of Recommendation Assessment， Deve-lopement an Evaluation. And 28 guidelines had five levels of recommendation strength. A total of 344 recommendations were extracted， including 86 strong-recommendations， 191 weak-recommendations （including 36 weak recommendations only based on expert consensus） and 67 recommendations with unclear recommendation strength. All guidelines had high scores in the three areas of “clinical questions （94.20%）”， “evidence （91.45%）” and “recommendations （89.06%）”， while the scores in the three areas of “registry （22.06%）”， “protocol （19.00%）” and “accessibility （31.51%）” were low. The STAR recommended stars of 8 guidelines were 5.0~4.0 stars， while that of 18 guidelines were 3.5~2.5 stars， and 8 guidelines were 2.0~1.0 stars. The three guidelines with the highest recommended stars were depressive disorder， community-acquired pneumonia， and influenza in adult. ConclusionThere is a certain gap in the quality of the published clinical practice guidelines of CPMs， and the quality of the guidelines could be further improved in registry， protocols， funds， and accessibility.

Objective·To explore the predictive value of diuretic renal scintigraphy parameters such as 20-minute residual rate(R20)for pyeloplasty in children with congenital unilateral ureteropelvic junction obstruction(UPJO).Methods·The clinical data and diuretic renal scintigraphy results of 110 children with congenital unilateral UPJO who were first treated at the Department of Nuclear Medicine,Xinhua Hospital,Shanghai Jiao Tong University School of Medicine from August 2018 to August 2023 were retrospectively analyzed.The imaging results and the progress of hydronephrosis were followed up after the first diuretic renal scintigraphy.According to the outcome event of pyeloplasty due to the progression of hydronephrosis,the children were divided into operation group and non-operation group.Age,gender,side of hydronephrosis,and baseline diuretic renal scintigraphy parameters including blood perfusion rate(BPR),differential renal function(DRF),time to peak(Tmax),time to half(T1/2)and R20 were compared between the two groups.Logistic regression was used to analyze the effect of various parameters on the progression of hydronephrosis.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of diuretic renal scintigraphy parameters for surgical intervention.Wilcoxon test was used to compare the examination parameters of two diuretic renal dynamic imaging.Results·During the follow-up,60 children underwent pyeloplasty after progression,and the other 50 children did not progress.The differences in DRF,Tmax,T1/2 and R20 between the two groups of children at baseline were statistically significant(all P<0.05).Univariate and multivariate Logistic regression analysis showed that only R20 was an independent predictor of pyeloplasty(OR=4.730,95%CI 1.009-1.178,P=0.030).R20 predicted pyeloplasty with a sensitivity of 88.3%,specificity of 56%,the area under the ROC curve of 0.758(95%CI 0.667-0.850,P=0.000),and the cut-off value of 90.08%.During the follow-up,38 children underwent the second diuretic renal scintigraphy,and the DRF was lower than before.The difference between the two DRFs was statistically significant(Z=-2.589,P=0.010),especially in children with R20≥90.08%(Z=-2.166,P=0.030).R20 in the non-operation group decreased significantly compared with the baseline(Z=-2.062,P=0.039).However,R20 in the operation group was higher than baseline,but the difference was not statistically significant(P>0.05).Conclusion·R20 plays an important role in the prediction of pyeloplasty in children with congenital unilateral UPJO.For children with R20≥90.08%,pyeloplasty should be performed as soon as possible to prevent further deterioration of renal function.

Objective:To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes.Methods:The clinical data of children with septic shock in children′s PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results:A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs ( OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions:The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Objective:To investigate the clinical features, pathogen composition, and prognosis of septic shock in pediatric intensive care units (PICU) in China.Methods:A multicenter retrospective cohort study. A retrospective analysis was conducted on the clinical data of children with septic shock from 10 hospitals in China between January 2018 and December 2021. The clinical features, pathogen composition, and outcomes were collected. Patients were categorized into malignant tumor and non-malignant tumor groups, as well as survival and mortality groups. T test, Mann Whitney U test or Chi square test were used respectively for comparing clinical characteristics and prognosis between 2 groups. Multiple Logistic regression was used to identify risk factors for mortality. Results:A total of 1 247 children with septic shock were included, with 748 males (59.9%) and the age of 3.1 (0.9, 8.8) years. The in-patient mortality rate was 23.2% (289 cases). The overall pathogen positive rate was 68.2% (851 cases), with 1 229 pathogens identified. Bacterial accounted for 61.4% (754 strains) and virus for 24.8% (305 strains). Among all bacterium, Gram negative bacteria constituted 64.2% (484 strains), with Pseudomonas aeruginosa and Enterobacter being the most common; Gram positive bacteria comprised 35.8% (270 strains), primarily Streptococcus and Staphylococcus species. Influenza virus (86 strains (28.2%)), Epstein-Barr virus (53 strains (17.4%)), and respiratory syncytial virus (46 strains (17.1%)) were the top three viruses. Children with malignant tumors were older and had higher pediatric risk of mortality (PRISM) Ⅲ score, paediatric sequential organ failure assessment (pSOFA) score (7.9 (4.3, 11.8) vs. 2.3 (0.8, 7.5) years old, 22 (16, 26) vs. 16 (10, 24) points, 10 (5, 14) vs. 8 (4, 12) points, Z=11.32, 0.87, 4.00, all P<0.05), and higher pathogen positive rate, and in-hospital mortality (77.7% (240/309) vs. 65.1% (611/938), 29.7% (92/309) vs. 21.0% (197/938), χ2=16.84, 10.04, both P<0.05) compared to the non-tumor group. In the death group, the score of PRISM Ⅲ, pSOFA (16 (22, 29) vs. 14 (10, 20) points, 8 (12, 15) vs. 6 (3, 9) points, Z=4.92, 11.88, both P<0.05) were all higher, and presence of neoplastic disease, positive rate of pathogen and proportion of invasive mechanical ventilation in death group were also all higher than those in survival group (29.7% (87/289) vs. 23.2% (222/958), 77.8% (225/289) vs. 65.4% (626/958), 73.7% (213/289) vs. 50.6% (485/958), χ2=5.72, 16.03, 49.98, all P<0.05). Multiple Logistic regression showed that PRISM Ⅲ, pSOFA, and malignant tumor were the independent risk factors for mortality ( OR=1.04, 1.09, 0.67, 95% CI 1.01-1.05, 1.04-1.12, 0.47-0.94, all P<0.05). Conclusions:Bacterial infection are predominant in pediatric septic shock, but viral infection are also significant. Children with malignancies are more severe and resource consumptive. The overall mortality rate for pediatric septic shock remains high, and mortality are associated with malignant tumor, PRISM Ⅲ and pSOFA scores.

Objective:To visualize and analyze the literature related to nurses′ psychological contract at home and abroad by CiteSpace software, discuss the development trend, and to provide reference for subsequent research.Methods:Literature related to nurses′ psychological contract collected by China National Knowledge Infrastructure and Web of Science from the establishment of the database to August 31, 2023 were retrieved. CiteSpace software was used to visually process the authors, institutions, keywords, publication trends and other types of nodes. Combined with the visualization map, the research status and hot trends of nurses′ psychological contract were analyzed.Results:A total of 175 articles in English and 126 articles in Chinese were included. The annual publication volume showed a zigzag upward trend. Chen Furong′s team published the most Chinese literature, while Rodwell J′s team published the most English literature. Shanxi Medical University and Monash University were the research institutions with the largest number of publications in Chinese and English respectively. Domestic research hotspots mainly focused on 5 directions: the status quo investigation, influence factors, intervention strategies, the impact on performance behavior, the content and structure of nurses′ psychological contract. Foreign research hotspots mainly focused on 3 directions: the influence factors, intervention strategies and the impact on performance behavior.Conclusions:The overall number of papers published in the field of nurses′psychological contract research at home and abroad is small, and the depth and breadth of the research are far from enough. The cooperation between authors and institutions should be strengthened, the research direction should be more diversified, and the mediation effect analysis and influence mechanism research of psychological contract should be paid attention to, so as to construct a multipath nurses′psychological contract system complied with national condition.

Objective: Narrative exposure therapy (NET) has been used in various contexts for the treatment of the effects of trauma, with promising results in clinical trials. However, its effects on anxiety and depression are still unclear. The present study is a systematic review and meta-analysis of the effects of NET on depression and anxiety. Methods: The Embase, Cumulative Index of Nursing and Allied Health Literature, PubMed, Web of Science core collection, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Biomedical Database, and Wangfang databases were searched from the earliest records to March 2023. Two researchers independently screened the literature, extracted data, evaluated the risk of bias, and cross-checked the data. Meta-analysis was performed using the program RevMan 5.3. Results: Eleven randomized controlled trials with a total of 754 participants were included in the study. The results showed that NET reduced both the depression (standard mean difference [SMD]=-0.51, 95% confidence interval [CI] -0.73–-0.29, p<0.00001) and anxiety (SMD=-0.65, 95% CI -1.13–-0.18, p=0.007) scores of the patients. Furthermore, NET was found to alleviate negative emotions associated with guilt (mean difference [MD]=-3.60, 95% CI -5.52–-1.68, p=0.0005) and negative change (MD=-5.80, 95% CI -9.76–-1.83, p=0.004). Conclusion This analysis showed that NET can alleviate depression and anxiety. It may thus be used in clinical settings to alleviate patients’ negative feelings and aid their overall recovery.

Vasculitis, involving any levels of vessels throughout the body, has variable nonspecific clinical presentation and complicated classification, hence, the diagnose is difficult. The liver is not the major organ involved, so it is prone to overlook vasculitis-associated liver injuries. The main manifestations of vasculitis involving the liver include abnormal liver biochemistry test (mainly increase of cholestatic liver enzymes), portal hypertension, and hepatic occupying lesions. Treatment principles are primarily directed at systemic immunosuppressive therapy for vasculitis. This review summarized the classification of vasculitis, major presentations of liver involvement in vasculitis, and the principles of treatment, to improve the awareness of the rare vascular diseases.
