Systemic application of effective antifungal drugs is the basic treatment for pulmonary mycosis,meanwhile,drug spraying under bronchoscope is one of the most important treatment options for tracheal,bronchial and pulmonary mycosis.Compared with bronchoscopic drug injection,indwelling guided drug injection cannula through nasal suspension with or without anchoring has more advantages in the treatment of pulmonary mycosis,including the ability to connect to a syringe pump for continuous and slow injection of drugs,which can avoid repeatedly performing bronchoscopy.This article describes the standard operating procedure of indwelling nasal cannula with or without anchoring for the treatment of pulmonary mycosis.

Objective To investigate the impact of quercetin(Que)on postherpetic neuralgia(PHN)and chemokine ligand 3(CCL3,namely MIP-1α)/C-C chemokine receptor 1(CCR1)/C-C chemokine receptor 5(CCR5)signaling pathway in rats.Methods Sixty rats were divided into the control group(Con),the PHN group(model group),the L-Que(30 mg/kg)group,the M-Que(60 mg/kg)group,the H-Que(120 mg/kg)group and the H-Que+pathway activator MIP-1α(120 mg/kg Que+0.4 mg/kg recombinant MIP-1α)group.The mechanical paw withdrawal threshold(PWT)and thermal pain threshold(TWL)of rats were detected in each group.The kit was used to detect adenosine,Adenine ribonucleotide(AMP),adenosine diphosphate(ADP)and tumor necrosis factor in spinal dorsal horn samples-α(TNF-α),and interleukin-1 β(IL-1 β)levels in spinal dorsal horn samples.HE staining was applied to observe the pathological sections of spinal dorsal horn.Immunofluorescence staining was used to detect the activation of microglia in spinal dorsal horn.Western blot assay was applied to detect MIP-1α/CCR1/CCR5 signaling pathway protein expression.Results In the PHN group,the dorsal horn of the spinal cord was ruptured,the arrangement of nerve bundles was disordered,and inflammatory cell infiltration,edema,and slight atrophy of neurons appeared.Compared with the Con group,the PWT value,adenosine,AMP and ADP levels were obviously decreased in the PHN group(P＜0.05),and TWL value,TNF-α,IL-1β levels,the number of Iba1-positive microglia,MIP-1α,CCR1 and CCR5 protein levels were obviously increased(P＜0.05).After treatment with Que,the disordered arrangement of nerve bundles was improved,the infiltration of inflammatory cells was reduced,and the phenomenon of neuronal atrophy disappeared.Compared with the PHN group,the PWT value,adenosine,AMP and ADP levels were obviously increased in the L-Que group,the M-Que group and the H-Que group(P＜0.05).TWL value,TNF-αand IL-1β levels,the number of Iba1-positive microglia,and MIP-1α,CCR1 and CCR5 protein levels were obviously decreased(P＜0.05).The effect of Que was dose dependent.Compared with the H-Que group,PWT value,adenosine,AMP and ADP levels were obviously decreased in the H-Que+MIP-1α group(P＜0.05),and TWL value,TNF-α,IL-1β levels,the number of Iba1 positive microglia,MIP-1α,CCR1 and CCR5 protein levels were obviously increased(P＜0.05).Conclusion Que may reduce the inflammatory response in rats by inhibiting the MIP-1α/CCR1/CCR5 signaling pathway,thereby reducing PHN.

Recognizing upper airway obstruction and stenosis is critical to determine the subsequent treatment options in patients with obstructive sleep apnea(OSA).Drug-induced sleep endoscopy(DISE)is a 3D visual evaluation technology for the anatomical structure of the upper respiratory tract of OSA patients during"sleeping"state after being anesthetized.The dynamic situation of upper respiratory tract obstruction and collapse can be observed safely and quickly through endoscopy,which provides important reference for formulating surgical methods and positive airway pressure(PAP)intervention treatments.With the assistance of polysomnography(PSG),DISE plays an important role in optimizing individualized treatment plans for OSA.The present article introduces the technical operating points of PSG-assisted drug-induced sleep endoscopic positive airway pressure titration.

Purpose::To assess the value of the driving pressure variation rate (ΔP%) in predicting the outcome of weaning from invasive mechanical ventilation in patients with acute respiratory distress syndrome.Methods::In this case-control study, a total of 35 patients with moderate-severe acute respiratory distress syndrome were admitted to the intensive care unit between January 2022 and December 2022 and received invasive mechanical ventilation for at least 48 h were enrolled. Patients were divided into successful weaning group and failed weaning group depending on whether they could be removed from ventilator support within 14 days. Outcome measures including driving pressure, PaO 2:FiO 2, and positive end-expiratory pressure, etc. were assessed every 24 h from day 0 to day 14 until successful weaning was achieved. The measurement data of non-normal distribution were presented as median (Q 1, Q 3), and the differences between groups were compared by Wilcoxon rank sum test. And categorical data use the Chi-square test or Fisher's exact test to compare. The predictive value of ΔP% in predicting the outcome of weaning from the ventilator was analyzed using receiver operating characteristic curves. Results::Of the total 35 patients included in the study, 17 were successful vs. 18 failed in weaning from a ventilator after 14 days of mechanical ventilation. The cut-off values of the median ΔP% measured by Operator 1 vs. Operator 2 in the first 4 days were ≥ 4.17% and 4.55%, respectively ( p < 0.001), with the area under curve of 0.804 (sensitivity of 88.2%, specificity of 64.7%) and 0.770 (sensitivity of 88.2%, specificity of 64.7%), respectively. There was a significant difference in mechanical ventilation duration between the successful weaning group and the failure weaning group (8 (6, 13) vs. 12 (7.5, 17.3), p = 0.043). The incidence of ventilator-associated pneumonia in the successful weaning group was significantly lower than in the failed weaning group (0.2‰ vs. 2.3‰, p = 0.001). There was a significant difference noted between these 2 groups in the 28-day mortality (11.8% vs. 66.7%, p = 0.003). Conclusion::The median ΔP% in the first 4 days of mechanical ventilation showed good predictive performance in predicting the outcome of weaning from mechanical ventilation within 14 days. Further study is needed to confirm this finding.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
