ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough （AC） by Xiaoer Huatan Zhike granules （XEHT） based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin （OVA） and 100 mg aluminum hydroxide， a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model， low-， medium- and high-dose （1， 5， 20 g·kg^-1， respectively） XEHT， and sodium montelukast （1 mg·kg^-1） groups （n=6）， and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage， and those in the blank and model groups received the same volume of normal saline by gavage， 1 time·d^-1. After 10 consecutive days of drug administration， the guinea pigs were stimulated by 1% OVA nebulization， and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein （CRP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， superoxide dismutase （SOD）， and malondialdehyde （MDA） in the bronchoalveolar lavage fluid （BALF） and immunoglobulin G （IgG） and immunoglobulin A （IgA） in the serum. Immunohistochemistry （IHC） was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6， interleukin-1β （IL-1β）， and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group， the model group showed increased coughs （P<0.01）， elevated levels of CRP， TNF-α， IL-6， and MDA and lowered level of SOD in the BALF （P<0.05， P<0.01）， elevated levels of IgA and IgG in the serum （P<0.05， P<0.01）， congestion of the lung tissue and infiltration of inflammatory cells， increased expression of IL-6 and TNF-α （P<0.01）， large areas of low electron density edema in type Ⅱ epithelial cells， obvious swelling and vacuolization of the organelles， karyopyknosis or sparse and dissolved chromatin， and up-regulated mRNA levels of IL-6， IL-1β， and TNF-α （P<0.01）. Compared with the model group， the drug administration groups showed reduced coughs （P<0.01）， lowered levels of CRP， TNF-α， IL-6， and MDA and elevated level of SOD in the BALF （P<0.05， P<0.01）， alleviated lung tissue congestion， inflammatory cell infiltration， and type Ⅱ epithelial cell injury， and decreased expression of IL-6 and TNF-α （P<0.01）. In addition， the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG （P<0.05， P<0.01）. The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6， IL-1β， and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α （P<0.05， P<0.01）. Phospholipase D， mammalian target of rapamycin （mTOR）， and epidermal growth factor receptor family of receptor tyrosine kinase （ErbB） signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D， mTOR， and ErbB signaling pathways.

Purpose To explore the role and mechanism by which the forkhead box C1(FOXC1)promoter up-stream transcript(FOXCUT)regulates proliferation and invasion of non-small cell lung carcinoma(NSCLC)cells.Methods Bioinformatic analysis and RT-qPCR were used to quantify FOXCUT expression in NSCLC tissues.After FOXCUT knockdown in NSCLC cell lines,cell proliferation was examined using CCK-8 and EdU assays,and invasion was evaluated by Transwell assay.The expression of E-cadherin,vimentin,N-cadherin,and FOXC1 was detected by Western blot.FOXCUT-silenced H460 cells were constructed using lentiviruses and subcutaneously injected into nude mice to observe tumor growth.To rescue FOXC1 expression,an FOXC1 expression plasmid was transfected into FOX-CUT-knockdown cells.LncBook 2.0,ENCORI,and TargetScan databases were queried to predict miRNAs that inter-act with FOXCUT and FOXC1.Results FOXCUT expression was significantly higher in NSCLC tissues than in normal lung tissues(normal:0.24±0.22 vs NSCLC:0.68±0.76,t=5.94,P＜0.001),and patients with high FOXCUT expression had a poorer prognosis(P＜0.01).FOXCUT interference markedly repressed NSCLC cells' proliferation and invasion(P＜0.01).FOXCUT knockdown significantly upregulated E-cadherin and downregulated vimentin and N-cadherin(P＜0.01).In vivo,FOXCUT-silenced cells formed significantly smaller tumors in nude mice(P＜0.01).FOXCUT knockdown markedly reduced FOXC1 expression(P＜0.01).Overexpression of FOXC1 in FOX-CUT-depleted cells rescued cell proliferation(P＜0.01).Bioinformatic analysis identified 8 miRNAs potentially co-regulated by FOXCUT and FOXC1.Conclusion Knockdown of FOXCUT restrains NSCLC cell proliferation and inva-sion,possibly through suppression of FOXC1 expression.

Objective:To analyze the clinical and radiographic effectiveness of a calcium silicate-based bioactive ceramic iRoot BP Plus? pulpotomy of immature permanent teeth with complicated crown fracture and to evaluate the factors influencing its long-term success rate.Methods:The digital medical records of patients under 13 years old who had undergone iRoot BP Plus? pulpotomy in the Department of Oral Emergency or the First Clinical Division,Peking University School and Hospital of Stomatology from March 2017 to September 2022 due to complicated crown fracture of anterior teeth,and had taken at least one post-operation apical radiograph were reviewed.The clinical and radiographic information at the initial examination and follow-up period were obtained,including crown color,mobility,percussion,cold test(partial pulpotomy teeth),dental restoration,fistula,swelling or inflammation of the gingival tissue,the formation of apical foramen,pathologic radiolucency and calcification of pulp chamber or root canal obliteration.Data were tested by Fisher exact test and a multiple comparison.Results:In the study,64 patients including 37 males(57.8％)and 27 females(42.2％)with a mean age of 9.1 years were finally enrolled.The total number of permanent teeth that received pulpotomy was 75,and the average follow-up time was 19.3 months.The success rate was 93.1％with the time interval between dental injury and treatment in 24 h,while the success rate dropped to 88.2％with the time intervals beyond 24 h.The time intervals did not significantly affect the pulp survival rate(P=0.61)after pulpotomy(partial or co-ronal).The success rate 6 months after pulpotomy was 96.0％,and one-year success rate was 94.7％.A total of 23 cases were reviewed for more than 2 years after pulpotomy,and 6 cases failed.The mobility had no significant effect on the success rate(P=0.28).Pulp chamber calcification and pulp canal obli-teration were not observed in all the post-operative radiographs.Conclusion:The one year clinical and radiographic success rates obtained in this study indicate that iRoot BP Plus? is an appropriate pulp cap-ping material option for pulpotomy treatment of complicated crown fracture in immature permanent teeth without displacement injuries.This technique has broad promotional value.

Objective:To analyze the clinical characteristics and outcomes of patients with invasive fungal sinusitis (invasive fungal rhinosinusitis, IFR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and explored the risk factors for IFR after allo-HSCT.Methods:Nineteen patients with IFR after allo-HSCT at Peking University People’s Hospital from January 2012 to December 2021 were selected as the study group, and 95 patients without IFR after allo-HSCT during this period were randomly selected as the control group (1:5 ratio) .Results:Nineteen patients, including 10 males and 9 females, had IFR after allo-HSCT. The median age was 36 (10–59) years. The median IFR onset time was 68 (9–880) days after allo-HSCT. There were seven patients with acute myeloid leukemia, five with acute lymphoblastic leukemia, two with myelodysplastic syndrome, two with chronic myeloid leukemia, one with acute mixed-cell leukemia, one with multiple myeloma, and one with T-lymphoblastic lymph node tumor. There were 13 confirmed cases and 6 clinically diagnosed cases. The responsible fungus was Mucor in two cases, Rhizopus in four, Aspergillus in four, and Candida in three. Five patients received combined treatment comprising amphotericin B and posaconazole, one patient received combined treatment comprising voriconazole and posaconazole, nine patients received voriconazole, and four patients received amphotericin B. In addition to antifungal treatment, 10 patients underwent surgery. After antifungal treatment and surgery, 15 patients achieved a response, including 13 patients with a complete response and 2 patients with a partial response. Multivariate analysis revealed that neutropenia before transplantation ( P=0.021) , hemorrhagic cystitis after transplantation ( P=0.012) , delayed platelet engraftment ( P=0.008) , and lower transplant mononuclear cell count ( P=0.012) were independent risk factors for IFR after allo-HSCT. The 5-year overall survival rates in the IFR and control groups after transplantation were 29.00%±0.12% and 91.00%±0.03%, respectively ( P<0.01) . Conclusion:Although IFR is rare, it is associated with poor outcomes in patients undergoing allo-HSCT. The combination of antifungal treatment and surgery might be effective.

Objective To observe the effect of flurbiprofen axetil on lung oxygenation function,re-spiratory mechanics and pulmonary complications in patients undergoing thoracoscopic right lung lobectomy with endobronchial blockers during one-lung ventilation(OLV).Methods Sixty patients scheduled for elective thoracoscopic right lung lobectomy with endobronchial blockers for OLV,25 males and 35 females,aged 35-64 years,BMI 18-28 kg/m2,ASA physical status Ⅰ or Ⅱ,were randomly allocated into two groups:the flurbiprofen axetil group(group F)and the control group(group C),30 patients in each group.In group F,flurbiprofen axeil 1.0 mg/kg was injected intravenously 15 minutes before anesthesia induction,while group C was not treated.Blood gas analysis was performed in 2 ml of radial artery 20 minutes before anesthesia induction(T0),30 minutes(T1)and 60 minutes(T2)after OLV,and 15 minutes(T3)after two lung ventilation,then oxygenation index(OI)was calculated respectively and SpO2 was recorded.Pa-rameters of lung mechanics were monitored at T1 and T2 including peak airway pressure(Ppeak),airway platform pressure(Pplat),dynamic lung compliance(Cdyn),and ratio of null lumen volume to tidal vol-ume(VD/VT).The incidence of hypoxemia and the number of remedial cases during OLV were recorded.The postoperative transfer to ICU and complications such as atelectasis,acute lung injury and pneumonia within 72 hours after surgery were recorded.Results Compared with group C,SpO2 at T1,PaO2 and OI at T1—T3,and Cdyn at T1 and T2 were significantly increased in group F(P＜0.05),Ppeak and VD/VT at T1 and T2,Pplat at T2 were significantly decreased in group F(P＜0.05).There were no hypoxemia and remedies occurred during OLV and no patients were transferred to ICU after surgery,no atelectasis,acute lung injury,and pneumonia occurred within 72 hours after surgery between the two groups.Conclusion For patients undergoing OLV with endobronchial blockers undergoing thoracoscopic right lung lobectomy,in-travenous flurbiprofen axetil before induction of anesthesia can help improve lung oxygenation and optimize respiratory parameters during one lung ventilation.
