Objective:To explore the predictive value of pre-treatment platelet-to-albumin ratio (PAR) in short-term prognosis of endoscopic treatment for cirrhosis with esophageal and gastric variceal bleeding(EGVB).Methods:By retrospective analysis method, the clinical data of 195 cirrhotic patients with EVGB from January 2019 to April 2022 treatment at Bengbu First People′s Hospital were collected and analyzed. The PAR was calculated according to platelet count and albumin. The independent risk factors that affecting 6-week rebleeding and death were analyzed by univariate and multivariate Cox regression, the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of PAR for rebleeding and death, and Kaplan-Meier survival analysis was used to evaluate the rebleeding rate and survival rate of patients with different PAR ratios.Results:Among 195 patients, 36 patients were rebleeding and 159 patients were non-rebleeding within 6 weeks; while 15 cases died and 180 cases survived. The platelet count, PAR in the rebleeding group were lower than those in the non-rebleeding group, the direct bilirubin, triglyceride, alanine transaminase, prothrombin time and mortality in the rebleeding group were higher than those in the non-rebleeding group: 74.0(66.5, 88.8) × 10 9/L vs. 98.0(85.0, 111.0)×10 9/L, 2.48(2.18, 2.78) vs. 3.35(2.81, 4.04), 18.5(14.0, 23.8) μmol/L vs. 16.0(11.0, 20.0) μmol/L, (4.73 ± 2.52) mmol/L vs. (3.94 ± 1.65) mmol/L, 36.0(27.0, 46.0)U/L vs. 21.0(13.3, 33.0)U/L, (14.78 ± 1.63) s vs. (13.47 ± 0.87) s, 36.11%(13/36) vs. 1.26%(2/159), there were statistical differences ( P<0.05). Cox multivariate regression showed that PAR, alanine transaminase were the independent risk factors for the rebleeding ( P<0.05), PAR was the independent risk factor for the death within 6 weeks ( P<0.05). The area under the curve (AUC) of PAR for predicting 6-week rebleeding and death was 0.876, 0.776, the cut-off was 2.94, 2.71, the specificity was 69.8%, 72.2%, the sensitivity was 94.4%, 73.3%, respectively. According to the cut-off of PAR to predict rebleeding, the 6-week rebleeding rate in the PAR≤2.94 group was higher than that in the PAR>2.94 group ( χ2 = 36.88, P<0.01). According to the cut-off of PAR to predict death, the 6-week mortality rate in the PAR≤2.71 group was higher than in the PAR>2.71 group ( χ2 = 16.44, P<0.01). Conclusions:PAR can be used as a predictor for rebleeding and death within 6 weeks of EGVB in cirrhotic patients.

ABSTRACT Objective: To investigate the relationship between fasting blood glucose (FBG) and carotid intima-media thickness (IMT) in premenopausal and postmenopausal women. Subjects and methods: The study enrolled 2,959 women seen at the Maanshan People's Hospital of Anhui Province from December 2013 to December 2018. Carotid IMT was measured using Doppler ultrasound. Linear regression and R smoothing curves were used to analyze the relationship between blood glucose level and carotid IMT in the premenopausal and postmenopausal groups. Results: Postmenopausal compared with premenopausal women had higher mean IMT (mIMT; 0.81 ± 0.23 mm versus 0.70 ± 0.14 mm, respectively, p < 0.001) and maximum IMT (maxIMT; 0.86 ± 0.35 mm versus 0.74 ± 0.16 mm, respectively, p < 0.001) values. On linear regression analysis, mIMT values increased with increasing FBG values when FBG level was ≤ 7 mmol/L, but no significance was found between FBG and maxIMT. After stratification by menopausal status, mIMT and maxIMT increased with increasing FBG when FBG was ≤ 7 mmol/L in the premenopausal group. In the postmenopausal group, mIMT and maxIMT increased with increasing FBG. After adjustment for covariate factors, the relationship between FBG and mIMT remained the same as before the adjustment, but when FBG was ≤ 11 mmol/L, the maxIMT increased with increasing FBG. In the stratification analysis, maxIMT increased with increasing FBG when FBG was ≤ 7 mmol/L in the premenopausal group, while both mIMT and maxIMT increased with increasing FBG when FBG was > 10 mmol/L in the postmenopausal group. Conclusion: Levels of FBG contributed more to increased IMT in postmenopausal than premenopausal women. The influence of FBG was greater on maxIMT than mIMT. Additionally, FBG was helpful in assessing focal thickening of the carotid intima.
Résumé
Fibroblast growth factors (FGF) are a group of structurally related polypeptides which constitute an elaborate signaling system with their receptors. Evidence accumulated in the years suggests that the FGF family plays a key role in the repair of central nervous system injury. The main protective mechanisms include activating the expression of PI3K-Akt, peroxisome proliferator-activated receptor (PPARγ) and other signals; inhibiting NF-κB-mediated inflammatory response, oxidative stress and apoptosis; regulating neuronal differentiation and neuronal excitability as well as participating in protection of neurovascular units and nerve function repair. This paper comprehensively summarizes the latest research progress in FGF signaling related to diseases of the central nervous system such as cerebral infarction, cerebral hemorrhage, traumatic brain injury, Alzheimer's disease, Parkinson's disease, epilepsy and depression, aiming to provide scientific basis and reference for the development of innovative FGF drugs for the prevention and treatment of neurological diseases.

Objective: To explore the application value of percutaneous peripheral interventional therapy in pulmonary atresia with intact ventricular septal (PA-IVS). Methods: Retrospective case summary. The data was collected from 25 children who were hospitalized at the Children's Hospital,Zhejiang University School of Medicine from August 2019 to August 2022, had been diagnosed with PA-IVS by echocardiography, and underwent interventional treatment. The sex, age, weight, operation time, radiation exposure time, and radiation dose of the patients were collected. The patients were divided into the arterial duct stenting group and the non-stenting group. Preoperative tricuspid annular diameters and Z scores, right ventricular length diameters, and right ventricular/left ventricular length-diameter ratios were compared by paired t-tests. Right ventricular systolic pressure difference, oxygen saturation, lactic acid before and after the surgery were compared for 24 children who received percutaneous balloon pulmonary valvuloplasty. Right ventricular improvement in 25 children after operation was analyzed. The correlation between postoperative oxygen saturation and postoperative right ventricular systolic blood pressure difference, the degree of pulmonary valve opening and the Z value of tricuspid valve ring in the non-stenting group were analyzed. Results: A total of 25 patients with PA-IVS were enrolled in the study, of whom 19 were males and 6 females, with an age at surgery of 12 (6, 28) days and a weight of (3.7±0.5) kg. One of them underwent only stenting of the arterial duct; 20 children underwent only percutaneous pulmonary valve perforation and balloon angioplasty; 4 children underwent both procedures. The Z-value of the tricuspid ring was -1.5±1.2 in the group with arterial duct stenting, and -0.1±0.4 in the group without stenting (t=2.77, P=0.010). The tricuspid regurgitant flow rate 1 month after surgery was significantly lower than the preoperative ((3.4±0.6) vs. (4.8±0.9) m/s, t=6.62,P<0.001). In the 24 children with percutaneous pulmonary valve perforation and balloon angioplasty, the preoperative right ventricular systolic blood pressure was (110±32) mmHg, and the postoperative systolic blood pressure was (52±19) mmHg (1 mmHg=0.133 kPa) (F=59.55, P<0.001). The factors that may affect postoperative oxygen saturation in 20 cases of non-stenting group were analyzed. The results suggested that the pre and post-operative right ventricular systolic blood pressure differences (r=-0.11, P=0.649), and the pulmonary valve orifice opening (r=-0.31, P=0.201) and tricuspid annulus Z value (r=-0.18, P=0.452) at 1 month after the operation were not significantly correlated with the postoperative oxygen saturation. Conclusions: Interventional therapy can be used as the first choice for one-stage operation of PA-IVS. Percutaneous pulmonary valve perforation and balloon angioplasty are more suitable for children with well-developed right ventricles, tricuspid annulus, and pulmonary arteries. While the smaller the tricuspid annulus, the more dependent it is on the ductus arteriosus and thus patients are more suitable for arterial duct stenting.

Lung cancer is the highest cancer-related mortality rate in the world, and is one of the most common malignancies. The standard treatment for early-stage non-small cell lung cancer (NSCLC) is radical lobectomy, while recent studies have found that sub-lobectomy of pulmonary nodules (≤2 cm) is not inferior to lobectomy and even improve the prognosis of the patients. These important findings will effectively and positively promote the formation of consensus and principles of wedge resection of pulmonary nodules (≤2 cm) in the field of thoracic surgery. The purpose of this study is to present a national expert consensus on wedge resection of pulmonary nodules (≤2 cm) in the field of thoracic surgery. The experts from Editorial Committee of Consensus on Wedge Resection of Lung Nodules (≤2 cm) (2023 Edition) jointly participated in the revision work. According to the clinical progress about the wedge resection of pulmonary nodules (≤2 cm) at home and abroad during recent years, experts jointly wrote Wedge Resection of Pulmonary Nodules (≤2 cm): a Consensus Statement by Specialists of Thoracic Surgery (2023 Edition), in combination with the homogeneous treatment principles of wedge resection in the field of thoracic surgery in China. This consensus was summarized from the following aspects: (1) Indications of wedge resection of pulmonary nodules (≤2 cm); (2) Resection range of pulmonary nodules (≤2 cm) required for wedge resection; (3) Excisable pulmonary nodules (≤2 cm) for wedge resection. This consensus finally put forward 8 recommended opinions, and sorted out 5 opinions which were still controversial and needed more evidence. The integrated opinions were generated through the discussion held among the experts of thoracic surgery from all over the country, making wedge resection of pulmonary nodules (≤2 cm) more appropriate for China and more standardized and homogeneous for clinical practice. In the future, more relevant researches should be accumulated based on the characteristics of lung cancer and its diagnosis and treatment in China, optimizing the treatment of pulmonary nodules (≤2 cm).

OBJECTIVE@#To analyze the effect of mechanical cardiopulmonary resuscitation (CPR) on patients with cardiac arrest with the vertical spatial pre-hospital emergency transport.@*METHODS@#A retrospective cohort study was conducted. The clinical data of 102 patients with out-of-hospital cardiac arrest (OHCA) who were transferred to the emergency medicine department of Huzhou Central Hospital from the Huzhou Emergency Center from July 2019 to June 2021 were collected. Among them, the patients who performed artificial chest compression during the pre-hospital transfer from July 2019 to June 2020 served as the control group, and the patients who performed artificial-mechanical chest compression (implemented artificial chest compression first, and implemented mechanical chest compression immediately after the mechanical chest compression device was ready) during pre-hospital transfer from July 2020 to June 2021 served as the observation group. The clinical data of patients of the two groups were collected, including basic data (gender, age, etc.), pre-hospital emergency process evaluation indicators [chest compression fraction (CCF), total CPR pause time, pre-hospital transfer time, vertical spatial transfer time], and in-hospital advanced resuscitation effect evaluation indicators [initial end-expiratory partial pressure of carbon dioxide (PETCO2), rate of restoration of spontaneous circulation (ROSC), time of ROSC].@*RESULTS@#Finally, a total of 84 patients were enrolled, including 46 patients in the control group and 38 in the observation group. There was no significant difference in gender, age, whether to accept bystander resuscitation or not, initial cardiac rhythm, time-consuming pre-hospital emergency response, floor location at the time of onset, estimated vertical height, and whether there was any vertical transfer elevator/escalator, etc. between the two groups. In the evaluation of the pre-hospital emergency process, the CCF during the pre-hospital emergency treatment of patients in the observation group was significantly higher than that in the control group [69.05% (67.35%, 71.73%) vs. 61.88% (58.18%, 65.04%), P < 0.01], the total pause time of CPR was significantly shorter than that in the control group [s: 266 (214, 307) vs. 332 (257, 374), P < 0.05]. However, there was no significant difference in the pre-hospital transfer time and vertical spatial transfer time between the observation group and the control group [pre-hospital transfer time (minutes): 14.50 (12.00, 16.75) vs. 14.00 (11.00, 16.00), vertical spatial transfer time (s): 32.15±17.43 vs. 27.96±18.67, both P > 0.05]. It indicated that mechanical CPR could improve the CPR quality in the process of pre-hospital first aid, and did not affect the transfer of patients by pre-hospital emergency medical personnel. In the evaluation of the in-hospital advanced resuscitation effect, the initial PETCO2 of the patients in the observation group was significantly higher than that of the patients in the control group [mmHg (1 mmHg ≈ 0.133 kPa): 15.00 (13.25, 16.00) vs. 12.00 (11.00, 13.00), P < 0.01], the time of ROSC was significantly shorter than that in the control group (minutes: 11.00±3.25 vs. 16.64±2.54, P < 0.01), and the rate of ROSC was slightly higher than that in the control group (31.58% vs. 23.91%, P > 0.05). It indicated that continuous mechanical compression during pre-hospital transfer helped to ensure continuous high-quality CPR.@*CONCLUSIONS@#Mechanical chest compression can improve the quality of continuous CPR during the pre-hospital transfer of patients with OHCA, and improve the initial resuscitation outcome of patients.

Résumé
OBJECTIVES@#Multiple myeloma (MM) is a plasma cell malignancy occurring in middle and old age. MM is still an incurable disease due to its frequent recurrence and drug resistance. However, its pathogenesis is still unclear. Abnormal amino acid metabolism is one of the important characteristics of MM, and the important metabolic pathway of amino acids participates in protein synthesis as basic raw materials. Aminoacyl transfer ribonucleic acid synthetase (ARS) gene is a key regulatory gene in protein synthesis. This study aims to explore the molecular mechanism for ARS, a key factor of amino acid metabolism, in regulating amino acid metabolism in MM and affecting MM growth.@*METHODS@#The corresponding gene number was combined with the gene expression profile GSE5900 dataset and GSE2658 dataset in Gene Expression Omnibus (GEO) database to standardize the gene expression data of ARS. GSEA_4.2.0 software was used to analyze the difference of gene enrichment between healthy donors (HD) and MM patients in GEO database. GraphPad Prism 7 was used to draw heat maps and perform data analysis. Kaplan-Meier and Cox regression model were used to analyze the expression of ARS gene and the prognosis of MM patients, respectively. Bone marrow samples from 7 newly diagnosed MM patients were collected, CD138+ and CD138- cells were obtained by using CD138 antibody magnetic beads, and the expression of ARS in MM clinical samples was analyzed by real-time RT-PCR. Human B lymphocyte GM12878 cells and human MM cell lines ARP1, NCI-H929, OCI-MY5, U266, RPMI 8266, OPM-2, JJN-3, KMS11, MM1.s cells were selected as the study objects. The expression of ARS in MM cell lines was analyzed by real-time RT-PCR and Western blotting. Short hairpin RNA (shRNA) lentiviruses were used to construct gene knock-out plasmids (VARS-sh group). No-load plasmids (scramble group) and gene knock-out plasmids (VARS-sh group) were transfected into HEK 293T cells with for virus packaging, respectively. Stable expression cell lines were established by infecting ARP1 and OCI-MY5 cells, and the effects of knockout valyl-tRNA synthetase (VARS) gene on proliferation and apoptosis of MM cells were detected by cell counting and flow cytometry, respectively. GEO data were divided into a high expression group and a low expression group according to the expression of VARS. Bioinformatics analysis was performed to explore the downstream pathways affected by VARS. Gas chromatography time-of-flight mass spectrometry (GC-TOF/MS) and high performance liquid chromatography (HPLC) were used to detect the valine content in CD138+ cells and ARP1, OCI-MY5 cells and supernatant of knockdown VARS gene in bone marrow samples from patients, respectively.@*RESULTS@#Gene enrichment analysis showed that tRNA processing related genes were significantly enriched in MM compared with HD (P<0.0001). Further screening of tRNA processing-pathway related subsets revealed that cytoplasmic aminoacyl tRNA synthetase family genes were significantly enriched in MM (P<0.0001). The results of gene expression heat map showed that the ARS family genes except alanyl-tRNA synthetase (AARS), arginyl-tRNA synthetase (RARS), seryl-tRNA synthetase (SARS) in GEO data were highly expressed in MM (all P<0.01). With the development of monoclonal gammopathy of undetermined significance (MGUS) to MM, the gene expression level was increased gradually. Kaplan-Meier univariate analysis of survival results showed that there were significant differences in the prognosis of MM patients in methionyl-tRNA synthetase (MARS), asparaginyl-tRNA synthetase (NARS) and VARS between the high expression group and the low expression group (all P<0.05). Cox regression model multivariate analysis showed that the high expression of VARS was associated with abnormal overall survival time of MM (HR=1.83, 95% CI 1.10 to 3.06, P=0.021). The high expression of NARS (HR=0.90, 95% CI 0.34 to 2.38) and MARS (HR=1.59, 95% CI 0.73 to 3.50) had no effect on the overall survival time of MM patients (both P>0.05). Real-time RT-PCR and Western blotting showed that VARS, MARS and NARS were highly expressed in CD138+ MM cells and MM cell lines of clinical patients (all P<0.05). Cell counting and flow cytometry results showed that the proliferation of MM cells by knockout VARS was significantly inhibited (P<0.01), the proportion of apoptosis was significantly increased (P<0.05). Bioinformatics analysis showed that in addition to several pathways including the cell cycle regulated by VARS, the valine, leucine and isoleucine catabolic pathways were upregulated. Non-targeted metabolomics data showed reduced valine content in CD138+ tumor cells in MM patients compared to HD (P<0.05). HPLC results showed that compared with the scramble group, the intracellular and medium supernatant content of ARP1 cells and the medium supernatant of OCI-MY5 in the VARS-shRNA group was increased (all P<0.05).@*CONCLUSIONS@#MM patients with abnormal high expression of VARS have a poor prognosis. VARS promotes the malignant growth of MM cells by affecting the regulation of valine metabolism.

【Objective】 To evaluate the predictive value of isoform [-2] proprostate-specific antigen, p2 PSA (p2PSA) and its derived indexes for prostate cancer in a Chinese cohort with PSA 4-20 ng/mL. 【Methods】 A total of 139 males scheduled for biopsy were enrolled in the prospective study from Nov.2021 to Jun.2022. The total PSA (tPSA), free PSA (fPSA), fPSA/tPSA (f/t) and p2PSA were collected, and the percentage of p2PSA(%p2PSA) and prostate health index(PHI) were calculated. The predictive value of p2PSA and its derived indexes were compared with traditional indexes with receiver operating characteristic (ROC) curve and Logistic analysis. 【Results】 Prostate cancer was found in 54 cases (38.8%). There were significant statistical differences in tPSA(10.68 vs.8.14, P=0.021), f/t(0.13 vs.0.16, P=0.006), p2PSA(30.25 vs.19.81, P<0.001), %p2PSA(21.52 vs.13.15, P<0.001) and PHI(64.3vs.38.2, P<0.001) between prostate cancer patients and non-prostate cancer patients. The area under the ROC curve (AUC) of tPSA, fPSA, %fPSA, p2PSA, %p2PSA and PHI were 0.63, 0.51, 0.63, 0.71, 0.73, and 0.80, respectively. The inclusion of %p2PSA and PHI significantly increased the prediction efficiency of the basic prediction model (AUCbase+PHI=0.81, AUCbase+%p2PSA=0.78, AUCbase=0.67). With 35 as the recommended cut-off value of PHI, the incidence of meaningless puncture was reduced by 25.8%(36/139). 【Conclusion】 The application of p2PSA and its derived indexes have good predictive value for patients with PSA 4-20 ng/mL. The combined detection of %p2PSA and PHI can significantly increase the detection efficiency of prostate cancer and reduce the incidence of meaningless prostate puncture by 25.8%.

Objective:To investigate the clinical efficacy and safety of Dupilumab on the treatment of asthma combined with atopic dermatitis (AD) and other type 2 inflammatory co-morbidities in children.Methods:Clinical data of children with asthma combined with AD, allergic rhinitis (AR) type 2 inflammatory co-morbidities who received Dupilumab treatment for 16 weeks or longer in the Pediatric Asthma and Allergy Clinic of the Second Hospital of Tianjin Medical University from April 1, 2021 to September 1, 2022 were retrospectively analyzed.The efficacy and safety of Dupilumab on the treatment of asthma combined with AD and AR in children were assessed by comparing clinical symptoms before and after 16 weeks of treatment, changes in the dosage of inhaled corticosteroids (ICS), lung function, fractional exhaled nitric oxide (FeNO), and peripheral blood eosinophil (EOS) count, and the incidence of adverse events, respectively.The correlation between the efficacy on AD, AR and asthma was assessed.Quantitative indicators that were normally distributed were compared by the paired samples t-test; otherwise, they were compared by rank- sum test.The correlation between different indicators was compared by Spearman rank correlation test. Results:(1) Ten children with asthma combined with AD, AR were recruited, including 8 males and 2 females, with the mean age of 9 (4-14) years.Three children were previously treated with subcutaneous immunotherapy (SCIT) prior to Dupilumab treatment, and 1 child was transferred to Dupilumab treatment because of a poor responsiveness to Omalizumab.(2) Improvement of asthma: after 16 weeks of treatment, asthma symptoms were well controlled in the 10 children, and none of them had acute asthma attacks.The childhood asthma control test for children and asthma control questionnaire findings were significantly improved from baseline (all P<0.05). Forced expiratory volume in the first second to the predicted value was significantly improved from baseline ( P<0.05). The dosage of ICS [all converted to Beclomethasone Dipropionate, 0 (0, 125.00) μg/d vs.400.00 (200.00, 400.00) μg/d] and FeNO level [11.00(9.00, 19.25)×10 -9vs.38.00(18.25, 56.75)×10 -9] significantly decreased from baseline (all P<0.05). Serum T-IgE testing before and after treatment were performed in 3 children, which were significantly reduced at 16 weeks of treatment compared with baseline (case 1: 2 759 kU/L vs.>5 000 kU/L; case 2: 1 432 kU/L vs.3 546 kU/L; case 3: 655 kU/L vs.1 000 kU/L, all P<0.05). (3) Improvement of asthma co-morbidities: The scoring atopic dermatitis scores, and patient-oriented eczema measure scores at each time point of follow-up decreased significantly compared with baseline (all P<0.001). The overall peripheral blood EOS count increased during the treatment period compared with baseline[1.18(0.62, 1.51)×10 9/L vs.1.01(0.54, 1.90)×10 9/L, P=0.444], although no significant difference was detected.Visual analog scale and total rhinitis medication scores decreased significantly compared with baseline (all P<0.05). (4) There was a positive correlation between baseline AD severity and the therapeutic efficacy on asthma ( r=0.697, P=0.025). (5) Safety: during the treatment, one case developed bilateral conjunctivitis and one developed bilateral bulbar conjunctival hemosiderosis, both of whom were improved after symptomatic treatment. Conclusions:Dupilumab treatment significantly improves clinical symptoms of asthma, AD and AR in children with asthma combined with AD, AR type 2 inflammatory co-morbidities, which also reduces ICS dosage, FeNO level, rhinitis medication and serum T-IgE level, and improve pulmonary function, with a good safety profile.It is a promising treatment to children with type 2 inflammatory disease who have a poor Omalizumab efficacy, and its combination with SCIT is a favorable etiologic treatment.

OBJECTIVE@#To evaluate the clinical efficacy of Huangqi Sijunzi decoction (HQSJZD) for treating cancer-related fatigue (CRF) of spleen and stomach Qi deficiency type after chemotherapy in patients with breast cancer.@*METHODS@#A total of 94 breast cancer patients who developed CRF of spleen and stomach Qi deficiency type after chemotherapy were randomized into chemotherapy group (n=47) and traditional Chinese medicine (TCM) + chemotherapy group (n=47). The patients in chemotherapy group received the AC or EC regimen and non-drug interventions including psychological counseling, and those in TCM + chemotherapy group received oral administration of HQSJZD in addition to chemotherapy for 21 days as a treatment cycle, after which improvement of fatigue was assessed using Modified Piper Fatigue Scale. The active ingredients and targets of HQSJZD were screened using the TCM System Pharmacology Analysis Platform (TCMSP); the CRF- and breast cancer-related disease targets were retrieved based on data from the GeneCards, NCBI gene and OMIM databases to construct the component-target network and the protein-protein interaction (PPI) network. GO functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes KEGG pathway enrichment analysis of the target genes were performed to construct the component-disease-pathway-target biological network. The binding strength of the major drug ingredients and CRF key targets were predicted using AutoDock software.@*RESULTS@#The scores for somatic fatigue, emotional fatigue and cognitive fatigue, along with the overall fatigue score, showed more significant improvements in TCM+chemotherapy group than in chemotherapy group (P < 0.001), and the response rate reached 89.4% in the combined treatment group. We identified 250 targets for HQSJZD, 2653 CRF-related genes, 15 329 breast cancer-related genes and 161 prescription-disease intersected targets, from which topological analysis identified 66 potential key targets. GO and KEGG enrichment analyses predicted multiple pathways related with the disease. Molecular docking results suggested that the core ingredients of HQSJZD showed high affinities to the key targets AKT1, CASP3, IL6, JUN and VEGFA, among which AKT1 might be the most important target for HQSJZD to treat CRF.@*CONCLUSION@#HQSJZD can obviously improve CRF symptoms in breast cancer patients possibly by regulating multiple signaling pathways including PI3K-Akt through AKT1.

OBJECTIVES@#To study the clinical features of children with colorectal polyps and the efficacy of endoscopic treatment.@*METHODS@#A retrospective analysis was performed on the medical data of 1 351 children with colorectal polyps who were admitted and received colonoscopy and treatment in the past 8 years, including clinical features and the pattern and outcomes of endoscopic treatment.@*RESULTS@#Among the 1 351 children, 893 (66.10%) were boys and 981 (72.61%) had an age of 2-<7 years, and hematochezia (1 307, 96.74%) was the most common clinical manifestation. Of all the children, 89.27% (1 206/1 351) had solitary polyps, and 95.77% (1 290/1 347) had juvenile polyps. The polyps were removed by electric cauterization with hot biopsy forceps (6 cases) or high-frequency electrotomy and electrocoagulation after snare ligation (1 345 cases). A total of 1 758 polyps were resected, among which 1 593 (90.61%) were pedunculated and 1 349 (76.73%) had a diameter of <2 cm. Postoperative complications included bleeding in 51 children (3.77%), vomiting in 87 children (6.44%), abdominal pain in 14 children (1.04%), and fever in 39 children (2.89%), while no perforation was observed. The children aged <3 years had the highest incidence rates of postoperative bleeding and fever (P<0.0125), and the children with a polyp diameter of ≥2 cm had significantly higher incidence rates of postoperative bleeding, vomiting, and fever (P<0.05).@*CONCLUSIONS@#Solitary polyps, pedunculated polyps, and juvenile polyps are common types of pediatric colorectal polyps. Electric cauterization with hot biopsy forceps or high-frequency electrotomy and electrocoagulation after snare ligation can effectively remove colorectal polyps in children, with good efficacy and few complications. Younger age and larger polyp diameter are associated with a higher risk of postoperative bleeding.

@#The coming out of electromagnetic navigation bronchoscopy gives exciting solution for diagnosis and even treatment of peripheral pulmonary nodules. It breaks the barriers of traditional bronchoscopy, and gives live visible imaging guidance for operators during biopsy of peripheral pulmonary nodules. The electromagnetic navigation bronchoscopy system can intelligently recognize and reconstruct the bronchial tree of the patients, and generate visible data and virtual guidance for the operators. It can perceive real-time magnetic localization of the signal, so as to precisely guide the navigational or biopsy tools. This review introduced the artificial intelligence configuration of the electromagnetic navigation bronchoscopy system based on the Veran system, and gave some improvement advices based on the defects of the system. In this way, we hope to promote the development and better clinical application of electromagnetic navigation bronchoscopy system.

Objective:To explore the effect of repetitive transcranial magnetic stimulation (rTMS) combined with cognitive behavioral therapies (CBT) on the cognitive function and alcohol craving in patients with alcohol dependence.Methods:From March 2019 to September 2021, a total of 150 patients with alcohol dependence were enrolled and randomly divided into rTMS treatment group (rTMS+ sham CBT, n=41), CBT treatment group (CBT+ sham rTMS, n=34), rTMS+ CBT treatment group( n=36) and control group (sham rTMS+ sham CBT, n=39). At baseline (before treatment), 2nd week, 8th week, 12th week and 24th week, alcohol dependence scale (ADS) was used to evaluate the degree of alcohol dependence, the obsessive compulsive drinking scale (OCDS) was used to assess patients' drinking craving, and Montreal cognitive assessment scale (MoCA) was used to assess the overall cognitive level of patients.SPSS 23.0 statistical software was used to compare the differences of ADS, OCDS and MoCA scale scores of the four groups by repeated measure ANOVA and simple effect analysis. Results:(1)The patients in the four groups were evaluated with ADS scale at baseline, 12th week and 24th week respectively.The interaction of group×time( F=1.279, P=0.279) and the main effect of group were not significant ( F=0.882, P=0.454), and the main effect of time was significant ( F=12.925, P<0.001) .Further simple effect analysis showed that the ADS score of rTMS+ CBT group was lower than that of baseline(14.48±5.70, 10.00±6.51) ( P=0.01) at 24th week.(2)Patients in the four groups were assessed with OCDs scale at baseline, 2nd week, 8th week, 12th week and 24th week, and the interaction of group×time was significant ( F=2.015, P=0.042). Further simple effect analysis showed that the OCDs scores of rTMS group and rTMS+ CBT group at each follow-up time node were lower than those at baseline period (all P<0.05). (3)Patients in the four groups were assessed with MoCA scale at baseline, 8th week, 12th week and 24th week, and the interaction of group×time was not significant ( F=1.660, P=0.106), and the main effect of group and the main effect of time were significant ( F=2.964, P=0.038; F=14.239, P<0.001). Further simple effect analysis showed that the score of MoCA scale in CBT group at the 24th week was higher than that at baseline (21.73±5.81, 24.60±3.98)( P=0.029), the score of MoCA scale in rTMS+ CBT group at the 24th week was higher than that at the 8th week (23.50±6.01, 25.95±2.87) ( P=0.006), and the score of MoCA scale in rTMS group at the 12th week was higher than that in control group (22.08±6.64, 26.64±2.46)( P=0.009). Conclusion:rTMS combined with CBT can be effective in improving alcohol craving and cognitive function in patients with alcohol dependence, and has a good long-term effect.
Résumé
Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Objective:To investigate the prevalence of sarcopenia and associated factors in hospitalized elderly patients.Methods:This was a cross-sectional study.A total of 578 patients admitted to the Geriatrics Department of our hospital were consecutively recruited according to the admission criteria.Patients were divided into the sarcopenia group(n=202, 34.95%)and non-sarcopenia group(n=376, 65.05%)based on the diagnostic criteria(2014)of the Asian Working Group for Sarcopenia.Their clinical data and laboratory parameters were collected.All patients underwent comprehensive geriatric assessment.Results:(1)The detection rate of sarcopenia in these hospitalized patients was 34.95%.(2)Age, free thyroxine(FT4), and the prevalences of diabetes and osteoporosis and the incidence of falls in the past year were higher while body mass index(BMI), calf circumference, hemoglobin(Hb), albumin(ALB), triglycerides(TG), low-density cholesterol(LDL), glycosylated hemoglobin(HbA1c)and free triiodothyronine(FT3)were lower in sarcopenia patients than in non-sarcopenia patients, with statistical significance.Scores on the mini-mental state examination(MMSE)and activities of daily living(ADL)were lower in sarcopenia patients than in non-sarcopenia patients while scores on nutritional risk screening 2002(NRS2002)and the FRAIL scale were higher, all with statistical significance.(3)Binary logistic regression analysis revealed that osteoporosis and FRAIL score were risk factors for sarcopenia( OR=9.083 and 2.505, P<0.001)and BMI, calf circumference and ADL score were protective factors for sarcopenia( OR=0.735, 0.774 and 0.967, P<0.05). (4)ROC analysis showed that the areas under the curve for FRAIL score, BMI, calf circumference and ADL score were 0.832, 0.805, 0.841 and 0.812, respectively, with threshold values at 2.5 points, 23.52 kg/m 2, 32.5 cm and 92.5 points.(5)The chi-square test for sarcopenia screening using various related factors found osteoporosis, calf circumference <32.5 cm and ADL <90 points had higher sensitivity(0.787, 0.807, 0.817)while FRAIL ≥ 3 points and BMI <23.5 had slightly lower sensitivity(0.683, 0.708), with each related factor having a high negative detection rate(0.833-0.888). Conclusions:The prevalence of sarcopenia in hospitalized elderly is more than 1/3.Osteoporosis and FRAIL score are risk factors for sarcopenia.BMI, calf circumference and ADL score are protective factors for sarcopenia.All relevant factors have practical clinical value and can be used for preliminary screening of sarcopenia.
Résumé
Objective To study the correlation between regional cerebral glucose metabolism and behavioral scores in middle cerebral artery occlusion(MCAO)model rats before and after the intervention of constraint induced movement therapy(CIMT),and the correlation between the natural recovery processand motor function recovery in MCAO model rats and the brain activation after CIMT intervention,and to further explore the mechanism of CIMT. Methods Twenty-two adult male Sprague-Dawley(SD)rats were randomly divided into an ischemic group treated with CIMT (CIMT,n=6),an ischemic group (Control,n=6),a sham-operated group(Sham,n=6),and a blank control group(Normal,n=4). The MCAO models of rats in the CIMT group and Control group were established by thread embolism method. The middle cerebral artery was not blocked during the operation for the Sham group,and the Normal group was not given any special treatment. After operation,rats in the CIMT group and Sham group were treated with CIMT. On the 7th day(d7)and the 22nd day(d22)after surgery,foot-fault test(FFT)and the beam balance and walking (BBW) test were used to evaluate the forelimb motor;micro positron emission tomography-computed tomography (micro PET/CT) imaging with fluorodeoxyglucose (18F-FDG) was used to scan the glucose metabolism in different brain regions of rats;Pearson correlation analysis was used to analyze the correlation between behavioral scores and glucose metabolism level in the CIMT group and Control group. Results On d7,the BBW score in the CIMT group and Control group was negatively correlated with glucose metabolism in the left insular cortex and the auditory cortex,and positively correlated with glucose metabolism in the right posterior hippocampus,superior colliculus,and inferior colliculus,with statistically significant differences;the FFT score was negatively correlated with glucose metabolism in the left somatosensory cortex, insular cortex and orbitofrontal cortex, and positively correlated with glucose metabolism in the right midbrain,with statistically significant differences. On d22, the BBW score in the CIMT group and Control group was positively correlated with glucose metabolism in the amygdala,caudate putamen,insular cortex and entorhinal cortex,and negatively correlated with glucose metabolism in the nucleus accumbens (Acb) core shell and caudate putamen in the right brain region,with statistically significant differences;the FFT score was negatively correlated with the entorhinal cortex in the right hemisphere and the difference was statistically significant. Conclusion The recovery of motor function promoted by CIMT was associated with the activation of both cerebral hemispheres in rats. The improvement of balance function promoted by CIMT in rats with cerebral ischemia was mainly related to the activation of Acb core shell in the right hemisphere. The recovery of fine grasping function promoted by CIMT may be related to the activation of the right entorhinal cortex.
Résumé
Food deprivation can rescue obesity and overweight-induced mood disorders, and promote mood performance in normal subjects. Animal studies and clinical research have revealed the antidepressant-like effect of calorie restriction, but little is known about the mechanism of calorie restriction-induced mood modification. Previous studies have found that astrocytes modulate depressive-like behaviors. Inositol 1,4,5-trisphosphate receptor type 2 (IP3R2) is the predominant isoform in mediating astrocyte Ca
