Objective To investigate the molecular mechanism of Shema Zhichuan Liquid in the treatment of neutrophilic asthma(NA)based on network pharmacology and in vivo experiments.Methods(1)The TCMSP,literature search and Swiss ADME and Swiss Target Prediction databases were used to search and screen the active components and their targets of Shema Zhichuan Liquid.OMIM,GeneCards,DisGeNET and DrugBank databases were used to search and screen NA disease-related targets.The intersection of the active components and NA disease-related targets of Shema Zhichuan Liquid was obtained through the microbiology platform to obtain the potential targets of Shema Zhichuan Liquid for the treatment of NA(common targets).Cytoscape 3.8 software was used to construct the network of"Chinese medicinals-active components-potential targets".The PPI network of potential targets was established by STRING database,and the core targets were obtained by analysing the built-in Mcode plug-in.The Metascape platform was used to enrich the gene ontology(GO),Kyoto Encyclopaedia of Genes and Genomes(KEGG)pathways for the potential targets.(2)BALB/C mice were acclimatised and fed for 1 week and randomly divided into a blank group,NA model group,low-dose group(2.5 g·kg-1)and high-dose group of Shema Zhichuan Liquid(10 g·kg-1),and control group of Dexamethasone(1 mg·kg-1);the NA mouse model was replicated by intraperitoneal injection of sensitizer(OVA+CFA)and nebulized inhalation excitation.OVA/CFA(20 μg OVA+75 μg CFA,0.3 mL)was injected intraperitoneally to sensitize on days 0,7 and 14 respectively,and 5%OVA suspension was nebulized on days 21-30(8 mL each time,40 minutes each time,once a day);1 hour before nebulisation,each group was administered by gastric gavage,and the Dexamethasone control group was administered by intraperitoneal injection once a day.The pathological changes of mouse lung tissue were observed by HE staining;IL-8 content in alveolar lavage fluid was detected by ELISA;mRNA expression levels of NLRP3 and CXCR2 were detected by RT-qPCR;and p-mTOR protein expression levels was detected by immunohistochemistry.Results(1)A total of 826 active component targets and 154 NA disease-related targets were obtained,and 51 potential targets(common targets)for the treatment of NA were obtained from the intersection of the active component and the NA disease-related targets of Shema Zhichuan Liquid.Through the network analysis of"Chinese medicinals-active components-potential targets",quercetin,lignocerotoxin,kaempferol,stigmasterol,naringenin and other key active components were obtained.The PPI network analysis of potential targets yielded 29 core targets,including AKT1,IL6,TNF,EGFR,NLRP3,RELA,MIF,CXCR2,VEGFA,etc..The GO functional enrichment analysis yielded 882 biological process entries,33 cellular component entries,and 61 molecular function entries;KEGG analysis yielded 142 signaling pathways,mainly involving TNF signaling pathway,influenza A signaling pathway,Toll-like receptor pathway,MAPK signaling pathway,mTOR signaling pathway and so on.(2)Results of animal experiments:compared with the blank group,mice in the NA model group showed obvious damage to the airway mucosa,structural disorders,a large number of inflammatory cells infiltration,mucosal congestion,oedema,obvious thickening of the alveolar wall,and narrowing of the alveolar lumen;the level of the inflammatory factor IL-8 in the alveolar lavage fluid was significantly elevated(P＜0.05);the mRNA expressions of NLRP3 and CXCR2 in the lung tissues of the mice were significantly up-regulated(P＜0.01),and the protein expression of p-mTOR was significantly increased.Compared with the NA model group,the structural arrangement of bronchial epithelial cells in the mice in the low-and high-dose groups of Shema Zhichuan Liquid was slightly disordered,with a small amount of inflammatory cell infiltration around the airways and blood vessels,and the congestion and edema of the bronchial mucosa were significantly reduced;the mRNA expression of CXCR2 in the lung tissues of the mice was significantly down-regulated(P＜0.01),and the level of expression of p-mTOR protein was significantly reduced.The IL-8 level in the vesicular lavage fluid of mice in the high-dose group was significantly reduced(P＜0.05);the mRNA expression of NLRP3 in the lung tissue of mice in the low-dose group was significantly down-regulated(P＜0.05).Conclusion The therapeutic effect of Shema Zhichuan Liquid on NA may be achieved through the key active components,such as quercetin,lignocerol and kaempferol,acting on the core targets,such as NLRP3 and CXCR2,and regulating the key signaling pathways,such as the TNF signaling pathway,the MAPK signaling pathway,the Toll-like signaling pathway,and the mTOR pathway.

Transradial access(TRA)for performing interventional diagnosis and treatment can reduce access site complications.However,TRA can still cause complications in the operated limb,including radial artery spasm,radial artery perforation,hemorrhage,hematoma,radial artery dissection,osteofascial compartment syndrome,nerve injury,pseudoaneurysm,arteriovenous fistula,and radial artery occlusion,among which radial artery spasm is the most commonly seen.At present,the clinical recognition,prevention and treatment of complications of surgical limbs are still insufficient.Therefore,this consensus aims to make a detailed introduction about the identification,prevention and nursing of nine major types of complications of the surgical limb in interventional diagnosis and treatment procedures via radial artery access,to propose 24 recommendations which may provide a reference for medical institutions in carrying out the nursing care for complications of the surgical limb in interventional diagnosis and treatment procedures via radial artery access,and to reduce the occurrence of complications in patients.(J Intervent Radiol,2024,33:465-471)

Objective:To investigate the clinical characteristics and early identification of spontaneous rupture of uterus caused by placenta percreta.Methods:The clinical data of 12 patients with spontaneous uterine rupture caused by placenta percreta and admitted to the First Affiliated Hospital of Zhengzhou University from June 2014 to December 2019 were collected. The age, gestational age, gestational history, clinical manifestations, diagnostic methods, uterine operation history, rupture location, surgical method, treatment and outcome were analyzed.Results:(1) General condition: the median age of pregnant women was 37 years (range: 30-43 years), and the median gestational week of uterine rupture was 29 +6 weeks (range: 18 +3-36 +3 weeks). (2) Clinical manifestation: among the 12 pregnant women, 9 showed different degrees of abdominal pain; chest distress accompanied by waist soreness, abdominal distension in 2 cases; one asymptomatic pregnant women was found with uterine rupture during elective cesarean section. Preoperative color Doppler ultrasonography indicated that 9 of the 12 pregnant women had peritoneal effusion, and 6 of them underwent diagnostic peritoneal puncture or posterior vault puncture for non-clotting blood extraction. (3) Uterine operation history and rupture location: among the 12 cases of spontaneous rupture of uterus caused by placenta percreta pregnant women, 10 had placenta previa after cesarean section, including 4 cases of rupture at the incision of the original cesarean section, 3 cases of rupture at the penetrating placental implantation of the lower segment of the anterior wall of the uterus, and 1 case of placenta percreta occurred at the myomectomy site of the right angle of the uterus. Among the 2 pregnant women with spontaneous uterine rupture caused by penetrating placental implantation without a history of cesarean section, 1 case with history of multiple abortions, and uterine rupture occurred at the bottom of the palace, 1 had rupture of placental penetrating implantation after hysteroscopic electroresection of endometrial polyps, and the uterine rupture occurred at the anterior wall of the lower segment of the uterus. (4) Maternal and fetal outcomes: 11 pregnant women were injected with suspension RBC and 1 pregnant woman was not injected with blood products. Nine cases underwent hysteroplasty and 3 cases underwent subtotal hysterectomy. There were 11 maternal survivors and 1 maternal death; 7 neonates survived and 6 stillbirths. Conclusions:Uterine rupture caused by placenta percreta is of great harm to mother and infant, due to its heterogeneity in clinical manifestations, which increases the possibility of misdiagnosis. For pregnant women with risk factors of placenta percreta, early diagnosis should be made during pregnancy. For those who have been diagnosed with placenta percreta, when there is typical or atypical uterine rupture, doctors should be alert to the occurrence of uterine rupture.

Objective To explore the effect of emergency nursing combined with predictive rehabilitation nursing on rehabilitation and prognosis of patients with acute stroke.

Objective The aim of the present study is to measure multi-directional strain in patients with hyperuricemia through 3-dimensional speckle-tracking echocardiography (3D-STE) in order to investigate the left ventricular function early changes and clinical application value of 3D-STE. Methods 3-dimension dynamic images of left ventricular full volume in Apical 4-chamber heart view was collected and stored. 3-dimensional specke-tracking technology was applied to measure and compare the left ventricular multi-directional strain of patients with hyperuricemia and healthy controls in order to evaluate the left ventricular systolic function. Results A total of 24 healthy controls and 38 patients with hyperuricemia were included into the study. Among them,patients with hyperuricemia were divided into simple hyperuricemia group(n=12), hyperuricemia complicated with hyperlipidemia group (n=16)and hyperuricemia complicated with both hyper-tension and hyperlipidemia group (n=10). The circumferential strain [(-18.8±4.4)% vs (-25.9±6.4)%, t=-3.48, P=0.001] and area strain [(-31.2±3.9)% vs (-36.8±7.1)%, t=-2.55, P=0.018] of patients with simple hyper-uricemia significantly decreased compared with healthy controls. Besides, the circumferential strain [(-19.9 ± 5.8)% vs (-25.9 ±6.4)%, t=-3.02, P=0.002], longitudinal strain [(-12.6 ±3.3)% vs (-14.4 ±2.5)%, t=-1.95, P=0.038] and area strain [(-29.9±6.6)% vs (-25.9±6.4)%, t=-3.15, P=0.001] of patients with hyperuricemia complicated with hyperlipidemia significantly decreased compared with healthy controls. Conclusion Myo-cardial strain of patients with hyperuricemia complicated with hyperlipidemia or not is both decreased, indicating a decline in left ventricular systolic function.

Objective To explore the risk factors for lower extremity amputation in patients with diabetic foot.Methods The clinical data of 1 771 patients with diabetic foot at the Air Force General Hospital of PLA from November 2001 to April 2015 were retrospectively analyzed.The patients were divided into the non-amputation and amputation groups.Within the amputation group , subjects were further divided into the minor and major amputation subgroups.Binary logistic regression analyses were used to assess the association between risk factors and lower extremity amputation.Results Among 1 771 patients with diabetic foot , 323 of them ( 18.24%) were in the amputation group ( major amputation: 41; minor amputation:282 ) and 1 448 ( 81.76%) in the non-amputation group.Compared with non-amputation patients, those in the amputation group had a longer hospital stay and higher estimated glomerular filtration rate(eGFR)levels.Fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), C-reaction protein (CRP), ESR, ferritin, fibrinogen and WBC levels of the amputation group were higher , while hemoglobin albumin, transferrin, TC, TG, HDL-C and LDL-C were lower than those of the non-amputation group (all P<0.05 ).The proportion of hypertension ( 52.48% vs 59.98%) , peripheral vascular disease ( PAD ) (68.11% vs 25.04%), and coronary heart disease (21.33% vs 28.71%) were different between the amputation and non-amputation groups (all P<0.05).Multivariable logistic regression analyses showed that Wagner′s grade , PAD and CRP were the independent risk factors associated with lower extremity amputation in hospitalized patients with diabetic foot.Conclusion Wagner′s grade, ischemia of lower limbs and infection are closely associated with amputation of diabetic foot patients.

Objective To assess the clinical diagnostic performance of liver stiffness measurement (LSM) and aspartate transaminase (AST)-to-platelet (PLT) ratio index (APRI) for liver fibrosis in chronic hepatitis B (CHB) patients with alanine aminotransferase (ALT) less than or equal to five times of the upper limit of normal (≤5×upper limit of normal [ULN]).Methods FibroScan,blood routine and liver function test were conducted at the day or one day before liver biopsy in 383 CHB patients with ALT≤5 × ULN.The Scheuer scoring system was used for liver histologic assessment.APRI was calculated.Based on the results of liver pathology,the areas under receiver operating characteristic curve (AUC) of LSM and APRI for diagnosis of liver fibrosis stage were compared.Results The median LSM were 5.10 kPa for S0 fibrosis stage,5.20 kPa for S1,6.60 kPa for S2,10.10 kPa for S3,and 18.80 kPa for S4.The median APRI values were 0.36,0.38,0.63,0.61 and 1.27,respectively.The AUC of LSM were 0.817 for ≥S2,0.891 for ≥S3 and 0.913 for ≥S4.And the AUC of APRI were 0.717 for ≥S2,0.711 for ≥S3 and 0.746 for ≥S4.The cut-offs of LSM values were 6.8 kPa for ≥S2,8.7 kPa for ≥S3,and 10.9 kPa for ≥S4.Conclusion LSM can accurately assess the degree of liver fibrosis in CHB patients with ALT ≤5 × ULN,which is superior to APRI in clinical utility.
