Methods: Eighty cases of severe pneumonia are randomly assigned to the Xuebijing treatment (forty cases) and the control group (forty cases), with the same routine therapy provided in both groups. Clinical effective rates, inflammatory factors and organ function were observed in both groups. Results: The effective rate was higher in Xuebijing group than that of the control group (80.0% vs. 67.5%, P<0.05). As compared with the control group, the LDH, α1-AG, α1-AT levels and the peak body temperature decreased markedly with the Xuebijing treatment going, and the secretion of TNF-α, IL-6, IL-8 was suppressed in Xuebijing group; but no significant difference was found in leptin level. Conclusion: Xuebijing Injection may show a protective effect in patients with severe pneumonia. The mechanism is possibly with the decreased secretion of TNF-α, IL-6, and IL-8.展开更多

The present study was undertaken to determine the plasma levels of visfatin in patients with severe pneumonia. METHODS：A total of 70 patients, including 40 patients with severe pneumonia （group A） and 30 patients with non severe pneumonia （group B） who had been admitted to the ICU from June 2009 to June 2010, were enrolled in this prospective study. And another 30 healthy physical examinees served as healthy controls （group C）. Patients were excluded if they suffered from severe diseases of the heart, brain and kidney, cancers, autoimmune diseases, or received special treatment in the latest month. The plasma levels of visfatin, IL-6, IL-8 and TNF-α were measured by ELISA, while the level of CRP was determined by immuneturbidimetry, and the routine blood test was performed. Blood gas analysis and Acute Physiology and Chronic Health Evaluation II （APACHE II） were performed in patients with pneumonia. Comparisons between the groups were conducted by Student＇s t test, ANOVA or nonparametric test. Correlation analysis was carried out by Pearson＇s correlation test or Spearman＇s rank-order correlation test. RESULTS：The plasma level of visfatin in group A was significantly higher than that in groups B and C （P〈0.001）, and the level of visfatin in group B was significantly higher than that in group C （P〈0.001）. The plasma level of visfatin was positively correlated with CRP, TNF-α, APACHE II and PMN% in patients with severe pneumonia （rho=0.653, r=0.554, r=0.558, r=0.484, respectively, P〈0.05 for all）, while it was negatively correlated with PaO2 and PaO2/FiO2 （rho=-0.422, r=-0.543, respectively, P〈0.05 for all）. CONCLUSION：Visfatin may be involved in the systematic inflammation response in patients with severe pneumonia as a pro-inflammatory cytokine, and it is valuable in assessing the severity of pneumonia..展开更多

The...The diagnosis of pathogenic bacteria in severe pneumonia is difficult and the prognosis is poor. Its outcome is closely related to bacterial pathogenicity and the timeliness and pertinence of antibiotic treatment. Therefore, early diagnosis is of great significance to the prognosis of patients. Sputum examination and culture is the gold standard for the diagnosis of pathogens of severe pneumonia. However, due to the long time of bacterial culture, the early use of antibiotics, the change of bacteria species, mixed infection and other problems, the results of bacterial culture in sputum are often false negative. With the continuous application of new molecular biology techniques in clinical detection, the classification of bacteria and microorganisms has deepened from the identification of phenotypic characteristics to the classification of gene characteristics. Sequencing analysis with 16S rDNA sequencing technology has the characteristics of high sequencing flux, large amount of data obtained, short cycle, and can more comprehensively reflect the species composition of microbial community, real species distribution and abundance information. In this paper, 16S rDNA sequencing technology was used to analyze the bacterial population composition in the sputum of severe pneumonia, and to explore a new method of etiological diagnosis.展开更多

Methods: severe pneumonia and febrile convulsion (n=100) treated in our hospital from January 2017 to January 2021 were analyzed. Combined with different treatment methods, 50 patients were included in the control group (routine nursing) and 50 patients in the observation group (personalized nursing). The application indicators of different interventions were compared. Results: After lactation, the treatment satisfaction of patients with severe pneumonia and febrile convulsion in the observation group (98.00%) was significantly higher than that in the control group (82.00%), P<0.05. The fever relief time, shock stop time and shock time in the observation group were shorter than those in the control group (P<0.05). In terms of complications, compared with the control group (18.00%), the incidence of complications in the observation group (2.00%) was lower (P<0.05). The quality of life score of observation group was higher than that of control group (P<0.05). The recurrence rate of epilepsy in observation group was lower than that in control group, but there was no significant difference between the two groups (P>0.05). There was no significant difference between the two groups before intervention (P>0.05). After intervention, the compliance score of observation group was higher than that of control group (P<0.05). Conclusion: severe pulmonary disease. During the treatment of inflammatory convulsions, personalized care can not only improve clinical symptoms, but also help reduce complications and improve quality of life.

文摘Objective:To investigate the expression level of interleukin-17D(IL-17D)in the serum of patients with severe pneumonia and its correlation with disease severity.Methods:This study included 50 patients with severe pneumonia who were diagnosed and treated in the hospital from May 2024 to May 2025.The expression level of IL-17D in the serum of all patients was recorded.Patients were divided into severe and mild groups based on their disease severity.Gender,age,disease duration,presence of fever,atelectasis,pneumothorax,interleukin-2(IL-2),interleukin-4(IL-4),interleukin-6(IL-6),and interleukin-17D were selected as independent variables.Statistical software SPSS 22.00 was used for univariate analysis,and variables with statistical significance in the univariate analysis were included in a multivariate logistic regression analysis to determine the correlation between IL-17D and the severity of severe pneumonia.Results:The results of this study showed that the level of IL-17D in patients with severe pneumonia was significantly higher than the normal threshold.Univariate analysis indicated that atelectasis,IL-2,IL-6,and IL-17D were statistically significant(P<0.05)and could be considered as influencing factors for the severity of severe pneumonia.Multivariate logistic regression analysis revealed that atelectasis(OR=2.141,95%CI:1.684–2.391),IL-2(OR=2.884,95%CI:2.240–3.614),IL-6(OR=2.571,95%CI:2.190–2.943),and IL-17D(OR=2.416,95%CI:2.093–2.735)were positively correlated with the severity of severe pneumonia.Conclusion:The expression level of IL-17D in the serum of patients with severe pneumonia is higher than the normal threshold and is positively correlated with disease severity.
文摘Objective:To explore the effect of implementing a time-sensitive incentive model combined with specialized rehabilitation nursing in patients with severe pneumonia and respiratory failure.Methods:Seventy-eight patients with severe pneumonia and respiratory failure admitted from January 2024 to February 2025 were selected and randomly divided into two groups using a computer-based random drawing method.The control group(39 patients)received routine nursing,while the observation group(39 patients)received a time-sensitive incentive model combined with specialized rehabilitation nursing.Lung function and adverse emotional states were compared between the two groups.Results:After 2 weeks of nursing,the lung function of the observation group was higher than that of the control group(P<0.05),and the adverse emotional states of the observation group were lower than those of the control group(P<0.05).Conclusion:Implementing a time-sensitive incentive model combined with specialized rehabilitation nursing in patients with severe pneumonia and respiratory failure can improve lung function and emotional state.
文摘Objective: To observe the effects of Xuebijing Injection (血必净注射液) in patients with severe pneumonia, and to explore the mechanism. Methods: Eighty cases of severe pneumonia are randomly assigned to the Xuebijing treatment (forty cases) and the control group (forty cases), with the same routine therapy provided in both groups. Clinical effective rates, inflammatory factors and organ function were observed in both groups. Results: The effective rate was higher in Xuebijing group than that of the control group (80.0% vs. 67.5%, P<0.05). As compared with the control group, the LDH, α1-AG, α1-AT levels and the peak body temperature decreased markedly with the Xuebijing treatment going, and the secretion of TNF-α, IL-6, IL-8 was suppressed in Xuebijing group; but no significant difference was found in leptin level. Conclusion: Xuebijing Injection may show a protective effect in patients with severe pneumonia. The mechanism is possibly with the decreased secretion of TNF-α, IL-6, and IL-8.
文摘BACKGROUND The pathophysiological characteristics of severe pneumonia complicated by respiratory failure comprise pulmonary parenchymal changes leading to ventilation imbalance,alveolar capillary injury,pulmonary edema,refractory hypoxemia,and reduced lung compliance.Prolonged hypoxia can cause acid-base balance disorder,peripheral circulatory failure,blood-pressure reduction,arrhythmia,and other adverse consequences.AIM To investigate sequential mechanical ventilation’s effect on severe pneumonia complicated by respiratory failure.METHODS We selected 108 patients with severe pneumonia complicated by respiratory failure who underwent mechanical ventilation between January 2018 and September 2020 at the Luhe Hospital’s Intensive Care Unit and divided them into sequential and regular groups according to a randomized trial,with each group comprising 54 patients.The sequential group received invasive and non-invasive sequential mechanical ventilation,whereas the regular group received invasive mechanical ventilation.Blood-gas parameters,hemodynamic parameters,respiratory mechanical parameters,inflammatory factors,and treatment outcomes were compared between the two groups before and after mechanical-ventilation treatment.RESULTS The arterial oxygen partial pressure and stroke volume variation values of the sequential group at 24,48,and 72 h of treatment were higher than those of the conventional group(P<0.05).The carbon dioxide partial pressure value of the sequential group at 72 h of treatment and the Raw value of the treatment group at 24 and 48 h were lower than those of the conventional group(P<0.05).The pH value of the sequential group at 24 and 72 h of treatment,the central venous pressure value of the treatment at 24 h,and the Cst value of the treatment at 24 and 48 h were higher than those of the conventional group(P<0.05).The tidal volume in the sequential group at 24 h of treatment was higher than that in the conventional group(P<0.05),the measured values of interleukin-6 and tumor necrosis factor-αin the sequential group at 72 h of treatment were lower than those in the conventional group(P<0.05),and the total time of mechanical ventilation in the sequential group was shorter than that in the conventional group,with a statistically significant difference(P<0.05).CONCLUSION Treating severe pneumonia complicated by respiratory failure with sequential mechanical ventilation is more effective in improving respiratory system compliance,reducing inflammatory response,maintaining hemodynamic stability,and improving patient blood-gas levels;however,from this study’s perspective,it cannot reduce patient mortality.
文摘BACKGROUND Severe pneumonia is a common severe respiratory infection worldwide,and its treatment is challenging,especially for patients in the intensive care unit(ICU).AIM To explore the effect of communication and collaboration between nursing teams on the treatment outcomes of patients with severe pneumonia in ICU.METHODS We retrospectively analyzed 60 patients with severe pneumonia who were treated at the ICU of the hospital between January 1,2021 and December 31,2023.We compared and analyzed the respiratory mechanical indexes[airway resistance(Raw),mean airway pressure(mPaw),peak pressure(PIP)],blood gas analysis indexes(arterial oxygen saturation,arterial oxygen partial pressure,and oxygenation index),and serum inflammatory factor levels[C-reactive protein(CRP),procalcitonin(PCT),cortisol(COR),and high mobility group protein B1(HMGB1)]of all patients before and after treatment.RESULTS Before treatment,there was no significant difference in respiratory mechanics index and blood gas analysis index between 2 groups(P>0.05).However,after treatment,the respiratory mechanical indexes of patients in both groups were significantly improved,and the improvement of Raw,mPaw,plateau pressure,PIP and other indexes in the combined group after communication and collaboration with the nursing team was significantly better than that in the single care group(P<0.05).The serum CRP and PCT levels of patients were significantly decreased,and the difference was statistically significant compared with that of nursing group alone(P<0.05).The levels of serum COR and HMGB1 before and after treatment were also significantly decreased between the two groups.CONCLUSION The communication and collaboration of the nursing team have a significant positive impact on respiratory mechanics indicators,blood gas analysis indicators and serum inflammatory factor levels in the treatment of severe pneumonia patients in ICU.

文摘The mortality of patients with severe pneumonia caused by H1N1 infection is closely related to viral replication and cytokine storm.However,the specific mechanisms triggering virus replication and cytokine storm are still not fully elucidated.Here,we identified hypoxia inducible factor-1α(HIF-1α)as one of the major host molecules that facilitates H1N1 virus replication followed by cytokine storm in alveolar epithelial cells.Specifically,HIF-1αprotein expression is upregulated after H1N1 infection.Deficiency of HIF-1αattenuates pulmonary injury,viral replication and cytokine storm in vivo.In addition,viral replication and cytokine storm were inhibited after HIF-1αknockdown in vitro.Mechanistically,the invasion of H1N1 virus into alveolar epithelial cells leads to a shift in glucose metabolism to glycolysis,with rapid production of ATP and lactate.Inhibition of glycolysis significantly suppresses viral replication and inflammatory responses.Further analysis revealed that H1N1-induced HIF-1αcan promote the expression of hexokinase 2(HK2),the key enzyme of glycolysis,and then not only provide energy for the rapid replication of H1N1 virus but also produce lactate,which reduces the accumulation of the MAVS/RIG-I complex and inhibits IFN-α/βproduction.In conclusion,this study demonstrated that the upregulation of HIF-1αby H1N1 infection augments viral replication and cytokine storm by cellular metabolic reprogramming toward glycolysis mainly through upregulation of HK2,providing a theoretical basis for finding potential targets for the treatment of severe pneumonia caused by H1N1 infection.
文摘BACKGROUND： As a cytokine highly expressed in internal organs, visfatin could be used as a biomarker of systemic inflammation response for chronic obstructive pulmonary diseases, but few studies have reported the use of visfatin in severe pneumonia. The present study was undertaken to determine the plasma levels of visfatin in patients with severe pneumonia. METHODS：A total of 70 patients, including 40 patients with severe pneumonia （group A） and 30 patients with non severe pneumonia （group B） who had been admitted to the ICU from June 2009 to June 2010, were enrolled in this prospective study. And another 30 healthy physical examinees served as healthy controls （group C）. Patients were excluded if they suffered from severe diseases of the heart, brain and kidney, cancers, autoimmune diseases, or received special treatment in the latest month. The plasma levels of visfatin, IL-6, IL-8 and TNF-α were measured by ELISA, while the level of CRP was determined by immuneturbidimetry, and the routine blood test was performed. Blood gas analysis and Acute Physiology and Chronic Health Evaluation II （APACHE II） were performed in patients with pneumonia. Comparisons between the groups were conducted by Student＇s t test, ANOVA or nonparametric test. Correlation analysis was carried out by Pearson＇s correlation test or Spearman＇s rank-order correlation test. RESULTS：The plasma level of visfatin in group A was significantly higher than that in groups B and C （P〈0.001）, and the level of visfatin in group B was significantly higher than that in group C （P〈0.001）. The plasma level of visfatin was positively correlated with CRP, TNF-α, APACHE II and PMN% in patients with severe pneumonia （rho=0.653, r=0.554, r=0.558, r=0.484, respectively, P〈0.05 for all）, while it was negatively correlated with PaO2 and PaO2/FiO2 （rho=-0.422, r=-0.543, respectively, P〈0.05 for all）. CONCLUSION：Visfatin may be involved in the systematic inflammation response in patients with severe pneumonia as a pro-inflammatory cytokine, and it is valuable in assessing the severity of pneumonia..

文摘The diagnosis of pathogenic bacteria in severe pneumonia is difficult and the prognosis is poor. Its outcome is closely related to bacterial pathogenicity and the timeliness and pertinence of antibiotic treatment. Therefore, early diagnosis is of great significance to the prognosis of patients. Sputum examination and culture is the gold standard for the diagnosis of pathogens of severe pneumonia. However, due to the long time of bacterial culture, the early use of antibiotics, the change of bacteria species, mixed infection and other problems, the results of bacterial culture in sputum are often false negative. With the continuous application of new molecular biology techniques in clinical detection, the classification of bacteria and microorganisms has deepened from the identification of phenotypic characteristics to the classification of gene characteristics. Sequencing analysis with 16S rDNA sequencing technology has the characteristics of high sequencing flux, large amount of data obtained, short cycle, and can more comprehensively reflect the species composition of microbial community, real species distribution and abundance information. In this paper, 16S rDNA sequencing technology was used to analyze the bacterial population composition in the sputum of severe pneumonia, and to explore a new method of etiological diagnosis.
文摘Objective: to explore the application value of personalized breastfeeding in children with severe pneumonia and febrile convulsion. Methods: severe pneumonia and febrile convulsion (n=100) treated in our hospital from January 2017 to January 2021 were analyzed. Combined with different treatment methods, 50 patients were included in the control group (routine nursing) and 50 patients in the observation group (personalized nursing). The application indicators of different interventions were compared. Results: After lactation, the treatment satisfaction of patients with severe pneumonia and febrile convulsion in the observation group (98.00%) was significantly higher than that in the control group (82.00%), P<0.05. The fever relief time, shock stop time and shock time in the observation group were shorter than those in the control group (P<0.05). In terms of complications, compared with the control group (18.00%), the incidence of complications in the observation group (2.00%) was lower (P<0.05). The quality of life score of observation group was higher than that of control group (P<0.05). The recurrence rate of epilepsy in observation group was lower than that in control group, but there was no significant difference between the two groups (P>0.05). There was no significant difference between the two groups before intervention (P>0.05). After intervention, the compliance score of observation group was higher than that of control group (P<0.05). Conclusion: severe pulmonary disease. During the treatment of inflammatory convulsions, personalized care can not only improve clinical symptoms, but also help reduce complications and improve quality of life. The family members are very satisfied with the nursing service, which greatly improves the nursing level and is worthy of clinical application.
文摘Objective:Despite trials and programs for the prevention of childhood mortality due to pneumonia,Ethiopia is among the top five countries with the highest number of deaths due to pneumonia.Although the prevalence of pneumonia has increased in the abovementioned trials,little is known about the recovery time from severe pneumonia and its predictors in the study area.Therefore,this study aimed to assess the time to recovery from severe pneumonia and its predictors among pediatric patients admitted to Mizan-Tepi University Teaching Hospital,Ethiopia,in 2022.Methods:A total of 591 children admitted for severe pneumonia were selected using simple random sampling.Data were entered into Epi-data version 4.4.2.1 and expor ted to STATA version 14 for analysis,and the assumptions of Cox propor tional hazard models and goodness of fit were assessed through Shoenfeld residual and Cox-Snell residual,respectively.Bivariate and multivariable Cox regression models were used to identify the predictors of mor tality.Results:This study revealed that 91.54%(95%confidence interval[CI]:89.00–93.53)of participants recovered with an incidence rate of 24.10(95%CI:22.15–26.21)per 100 person-day–observations.The hmedian recovery time of children was 4 days(95%CI:2–6).Children who were not exclusively breastfed(AHR=1.3;95%CI:1.03–1.66),who had a history of inability to suck/feed(AHR=0.81;95%CI:0.65–0.99)were independent predictors of the time to recovery.Conclusions:Children with severe pneumonia who had not exclusively breastfed and who had a history of inability to suck/feed were independent predictors of time to recovery.Therefore,all stakeholders and concerned health care providers should focus more on early diagnosis and management and hasten early recovery based on the identified factors.
文摘Objective:To analyze the curative effect of humidified high-flow nasal oxygen therapy combined with alveolar lavage in patients with severe pneumonia and respiratory failure.Methods:120 patients with severe pneumonia complicated with respiratory failure admitted to the Third People’s Hospital of Xining from July 2021 to December 2022 were randomly divided into two groups:group A and group B.The patients in group A were given humidified high-flow nasal oxygen therapy combined with alveolar lavage,whereas those in group B were given humidified high-flow nasal oxygen therapy.The treatment efficacy,blood gas analysis results,and differences in inflammatory mediators were compared between the two groups.Results:The curative effect in group A(96.67%)was significantly higher than that in group B(81.67%),P<0.05;the partial pressure of carbon dioxide(PaCO2),partial pressure of oxygen(PaO2),oxygen saturation(SpO2),and Horowitz index(P/F)of group A were significantly better than group B,P<0.05;the interleukin 6(IL-6),tumor necrosis factor alpha(TNF-α),and C-reactive protein(CRP)levels,white blood cell(WBC)count,serum procalcitonin(PCT),and neutrophil(N)percentage of group A were significantly lower than those of group B,P<0.05.Conclusion:For patients with severe pneumonia complicated with respiratory failure,alveolar lavage,on the basis of humidified high-flow oxygen therapy,can inhibit local inflammation,improve blood gas analysis results,promote disease recovery,and improve the clinical treatment effect。
