OBJECTIVE: To explore the clinical features of the sepsis in immunocompromised hosts and establish an early warning equation. METHODS: A retrospective study was conducted on sepsis patients admitted to the intensive care unit (ICU) of Binzhou Medical University Hospital from October 2011 to October 2022. General information, infection site, etiology results and drug susceptibility, clinical symptoms, inflammatory indicators, acute physiology and chronic health status evaluation II (APACHE II), sequential organ failure assessment (SOFA), incidence of immune paralysis, and outcome during hospitalization were collected. Based on whether they met the diagnostic criteria for immunocompromised hosts, patients were divided into immunocompromised group and immune normal group. The clinical information of the two groups were compared. Multivariate Logistic regression was used to analyze the risk factors of patients with immunocompromised sepsis and the regression equation model was initially established. Omnibus test and Hosmer-Lemeshow test were used to evaluate the model. RESULTS: A total of 169 patients with sepsis were included, including 61 in the immunocompromised group and 108 in the normal immune group. The top 3 infection sites in the immunocompromised group were bloodstream infection, pulmonary infection and abdominal infection. The top 3 infection sites in the normal immune group were pulmonary infection, bloodstream infection and abdominal infection. The infection rate of Gram-negative bacteria in the immunocompromised group was significantly lower than that in the normal group [49.2% (30/61) vs. 64.8% (70/108), P < 0.05]. The infection rate of Gram-positive bacteria [27.9% (17/61) vs. 13.9% (15/108)] and multidrug-resistant bacteria [54.1% (33/61) vs. 29.6% (32/108)] were significantly higher than those in normal immune group (both P < 0.05). In terms of clinical symptoms, the proportion of fever in the immunocompromised group was significantly lower than that in the immune normal group [49.2% (30/61) vs. 66.7% (72/108), P < 0.05]. Neutrophil count (NEU) and neutrophil percentage (NEU%) in the immunocompromised group were significantly lower than those in the normal immune group. Lymphocyte percentage (LYM%), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), APACHE II score, combined shock rate, incidence of immune paralysis, and mortality during hospitalization in the immunocompromised group were significantly higher than those in the normal immune group. Logistic regression analysis showed that NLR, CRP and PCT were risk factors for patients with immunocompromised sepsis (all P < 0.05). The above indicators were used as covariables to construct a Logistic regression equation, that was, Logit (P) = 0.025X₁+0.010X₂+0.013X₃-2.945, where X₁, X₂ and X₃ represent NLR, CRP and PCT respectively. Omnibus test and Hosmer-Lemeshow test show that the model fits well and has certain early warning value. CONCLUSIONS Patients with immunocompromised sepsis have more intense inflammatory response, with Gram-negative bacteria being the predominant pathogen, and a higher incidence of Gram-positive bacterial infections and multi-drug resistant infections. The severity of the disease, in-hospital mortality, the incidence of shock and the incidence of immune paralysis after sepsis were significantly higher. NLR, CRP and PCT were independent risk factors for sepsis in immunocompromised hosts. The regression equation constructed based on this may have early warning significance for patients with immunocompromised sepsis.

Objective:To understand the current situation of care needs for disabled elderly people, analyze the impact of the family environment and community services on the care needs and care pathways of older people with disabilities and to formulate effective interventions.Methods:A cross-sectional survey was conducted from August 2022 to March 2023 in five tertiary-level hospitals in Tangshan city. The survey included 332 elderly people who were disabled before hospitalization and their primary caregivers, who were selected using a convenience sampling method. The survey investigated their general information, degree of disability, family members′ support, children′s filial piety and old age ethical level, family relationships, and the care needs of the elderly people who were disabled. SPSS 22.0 was used for one-way and correlation analyses as well as multiple linear regression analyses, and AMOS 22.0 was used for the development of structural equations for path analysis.Results:Among 332 disabled elderly individuals, there were 166 males and 166 females each. The care needs score for elderly people with disabilities was 101.54 ± 16.38. The care needs of this population can be influenced by several factors, including the level of disability, number of chronic conditions, presence of chronic pain, filial piety and old age ethical level of caregivers, family relationships, and the availability of care services in the community or village. These factors had direct effects of 0.468, 0.155, -0.083, -0.350, -0.094, and 0.104, respectively.Chronic diseases and chronic pain indirectly affected the demand for care through the degree of incapacity (with respective indirect effect values of 0.065 and 0.049). Additionally, the demand for care was indirectly influenced by the level of filial piety and ethics of the caregiver through the degree of incapacity and the family relationships (an indirect effect value of -0.162).Conclusions:The care needs of the disabled elderly are high, and the personal physiology, family environment and community support of the disabled elderly will directly or indirectly affect their care needs. Therefore, many factors should be considered comprehensively considered to improve the quality of care of the disabled elderly.

Objective:To investigate the value of serum soluble programmed cell death protein 1 (sPD-1), soluble B7 homolog 5 (sB7-H5) and trefoil factor 2 (TFF2) in evaluating the severity of disease and the risk of death in patients with acute pancreatitis (AP).Methods:A prospective research method was adopted. Three hundred and twenty-eight patients with AP (AP group) from February 2020 to February 2021 in Xiangyang Central Hospital were selected, including 124 patients with mild AP (MAP), 106 patients with moderately severe AP (MSAP) and 98 patients with severe AP (SAP). The serum levels of sPD-1, sB7-H5 and TFF2 were measured by enzyme-linked immunosorbent assay and compared with 60 healthy people (healthy control group). The patients with AP were followed up for 90 d, 284 patients survived and 44 died. The amylase, C-reactive protein (CRP), procalcitonin (PCT), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), modified CT severity index (MCTSI), sPD-1, sB7-H5 and TFF2 were compared between the two groups. Pearson method was used for correlation analysis. Multivariate Logistic regression was used to analyze the independent risk factors of death in patients with AP. The efficacy of sPD-1, sB7-H5 and TFF2 in predicting the death in patients with AP was evaluated using the receiver operating characteristics (ROC) curve.Results:The sPD-1, sB7-H5 and TFF2 in AP group were significantly higher than those in healthy control group: (177.99 ± 17.81) ng/L vs. (50.20 ± 10.81) ng/L, (2.69 ± 0.72) μg/L vs. (1.40 ± 0.35) μg/L and (569.97 ± 38.91) μg/L vs. (94.59 ± 11.98) μg/L, and there were statistical differences ( P<0.01). The amylase, sPD-1, sB7-H5 and TFF2 in patients with MSAP and SAP were significantly higher than those in patients with MAP: (639.36 ± 91.67) and (835.24 ± 109.30) U/L vs. (575.24 ± 89.78) U/L, (180.13 ± 20.61) and (221.17 ± 15.70) ng/L vs. (142.03 ± 16.76) ng/L, (2.85 ± 0.74) and (3.34 ± 0.82) μg/L vs. (2.05 ± 0.52) μg/L, (539.66 ± 36.58) and (763.55 ± 40.08) μg/L vs. (442.90 ± 35.79) μg/L, the indexes in patients with SAP were significantly higher than those in patients with MSAP, and there were statistical differences ( P<0.01). Pearson correlation analysis result showed that sPD-1 was positively correlated with sB7-H5 and TFF2 in patients with AP ( r = 0.552 and 0.641, P<0.01), and the sB7-H5 was positively correlated with TFF2 ( r = 0.610, P<0.01). The amylase, CRP, PCT, APACHE Ⅱ, SOFA, MCTSI, sPD-1, sB7-H5 and TFF2 in the dead patients were significantly higher than those in the living patients: (1 098 ± 105) U/L vs. (641 ± 93) U/L, (235.60 ± 40.17) mg/L vs. (118.04 ± 32.90) mg/L, (4.32 ± 0.52) μg/L vs. (3.14 ± 0.44) μg/L, (19.39 ± 3.14) scores vs. (11.18 ± 2.53) scores, (12.13 ± 2.78) scores vs. (7.40 ± 2.15) scores, (7.12 ± 1.73) scores vs. (4.31 ± 1.52) scores, (222.23 ± 22.30) ng/L vs. (171.14 ± 18.50) ng/L, (3.37 ± 0.89) μg/L vs. (2.59 ± 0.59) μg/L and (629.27 ± 39.63) μg/L vs. (560.78 ± 30.45) μg/L, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that CRP, PCT, APACHE Ⅱ, SOFA, sPD-1, sB7-H5 and TFF2 were independent risk factors death of in patients with AP ( OR = 1.339, 1.416, 1.285, 1.327, 1.092, 1.171 and 1.080; 95% CI 1.145 to 1.566, 1.146 to 1.751, 1.132 to 1.460, 1.150 to 1.531, 1.024 to 1.164, 1.072 to 1.280 and 1.031 to 1.131; P<0.01). The ROC curve analysis result showed that the area under the curve of sPD-1, sB7-H5 and TFF2 combined detection to predict the death in patients with AP was larger than that of sPD-1, sB7-H5, and TFF2 alone detection (0.870 vs. 0.771, 0.734 and 0.685). Conclusions:The increase of serum sPD-1, sB7-H5 and TFF2 levels in patients with AP is related to the severity of disease of patients with AP. The combined detection of the indexes can assist in evaluating the risk of death in patients with AP.

Objective:To explore the effect of continuous blood purification (CBP) on the immunity and endothelial cell function of patients with sepsis.Methods:A prospective study was conducted. The patients aged ≥18 years old and meeting the diagnostic criteria of sepsis admitted to the department of critical care medicine of Binzhou Medical University Hospital from March 2019 to October 2020 were selected as the research subjects, and the patients were divided into standard treatment group and CBP treatment group according to random number table method. Both groups were given standard treatment including initial fluid resuscitation, infection source control and antibiotics according to the 2016 international guidelines for the management of sepsis and septic shock. CBP treatment group was additionally given continuous veno-venous hemofiltration (CVVH) at a dose of 25-30 mL·kg -1·h -1 and blood flow rate of 150-200 mL/min for more than 20 hours a day for 3 days. The clinical data of patients including blood lactic acid (Lac), procalcitonin (PCT), lymphocyte count (LYM), acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment (SOFA) score were recorded before treatment and 1 day and 3 days after treatment. At the same time, the venous blood was collected, and the immune function related indexes [interleukins (IL-4, IL-7), programmed death receptor-1 (PD-1), programmed death ligand-1 (PD-L1), interferon-γ (IFN-γ)] and endothelial cell injury related markers [soluble thrombomodulin (sTM), angiopoietin-2 (Ang-2), von Willebrand factor (vWF), heparan sulfate (HS), syndecan-1 (SDC-1)] levels in serum were determined by enzyme-linked immunosorbent assay (ELISA). The length of intensive care unit (ICU) stay of patients in the two groups was recorded, and the outcomes of patients in the two groups were followed up for 28 days. Results:Finally, 20 patients were enrolled in the standard treatment group, and 19 patients were enrolled in the CBP treatment group. There were no significant differences in gender, age and infection site between the two groups. The length of ICU stay in the standard treatment group was (10±5) days, and 5 patients died and 15 patients survived after 28 days. The length of ICU stay in the CBP treatment group was (9±4) days, and 8 patients died and 11 patients survived after 28 days. There were no significant differences in the length of ICU stay and number of patients who died within 28 days between the two groups (both P > 0.05). There were no significant differences in the Lac, PCT, LYM, APACHEⅡ score, SOFA score and immune function and endothelial cell injury related indexes before treatment and 1 day after treatment between the two groups. After 3 days of treatment, the Lac, PCT, APACHEⅡ score and SOFA score of the CBP treatment group were significantly lower than those before treatment, and pro-inflammatory and anti-inflammatory cytokines such as IFN-γ and IL-4, apoptosis-related indicators such as PD-1 and IL-7, and endothelial injury related factors such as sTM, SDC-1 and HS were significantly improved compared with the pre-treatment, the improvement degree of the above indicators was more obvious than that of the standard treatment group, and LYM was significantly higher than that of the standard treatment group (×10 9/L: 1.3±0.3 vs. 0.9±0.4, P < 0.05), IL-4, IFN-γ, IFN-γ/IL-4 ratio, IL-7, PD-1, sTM, SDC-1, HS, and Ang-2 were significantly lower than those of the standard treatment group [IL-4 (ng/L): 2.8 (1.5, 3.2) vs. 3.3 (2.7, 5.2), IFN-γ (ng/L): 6.3 (5.4, 106.5) vs. 217.9 (71.4, 517.1), IFN-γ/IL-4 ratio: 3.7 (1.8, 70.3) vs. 59.1 (18.3, 124.9), IL-7 (ng/L): 4.6 (3.2, 5.1) vs. 6.3 (5.2, 8.0), PD-1 (μg/L): 0.04 (0.03, 0.06) vs. 0.08 (0.05, 0.12), sTM (μg/L): 4.9 (4.3, 7.4) vs. 8.7 (6.0, 10.8), SDC-1 (μg/L): 0.6 (0.3, 1.1) vs. 0.9 (0.8, 2.5), HS (ng/L): 434.8 (256.2, 805.0) vs. 887.9 (620.1, 957.3), Ang-2 (ng/L): 934.0 (673.3, 1 502.1) vs. 2 233.9 (1 472.5, 3 808.4)], the differences were statistically significant (all P < 0.05). Conclusion:CBP treatment can eliminate the patient's immunosuppressive state, reduce a variety of endothelial injury markers and the degradation of glycocalyx, but cannot decrease the 28-day death risk or shorten the length of ICU stay.

The operation points and difficult points of equivalence demonstration for the products exempted from clinical evaluation were introduced in order to provide reference for medical device colleagues.

Objective:To explore the current status of readiness for young and middle-aged maintenance hemodialysis (MHD) patients to return to work and analyze its influencing factors, with the aim of providing reference for the evaluation and intervention of patients returning to work.Methods:From October to December 2022, convenience sampling was used to select 425 patients from six hospitals in the urban area of Yangzhou as the subject. A cross-sectional survey was conducted using the General Information Questionnaire, Readiness for Return-To-Work Scale (RRTWS), Distress Disclosure Index (DDI) and Perceived Social Support Scale (PSSS). Binary Logistic regression was used to analyze the influencing factors of returning to work.Results:Among 425 young and middle-aged patients undergoing MHD, 105 (24.7%) returned to work, of which 79 (75.2%) were in the uncertain maintenance stage and 26 (24.8%) were in the active maintenance stage. 320 did not return to work, including 148 (46.3%) in the pre-intention stage, 86 (26.9%) in the intention stage, 42 (13.1%) in the action preparation self-evaluation stage, and 44 (13.8%) in the action preparation behavior stage. Age, per capita monthly income of the family, number of comorbidities, level of self-disclosure, and level of perceived social support were factors that affected patients' readiness to return to work.Conclusions:The rate of young and middle-aged MHD patients returning to work needs to be improved. The return of patients to work is influenced by multiple factors. Medical and nursing staff should focus on patients who are old, have low per capita monthly income of the family, and have a large number of comorbidities. Targeted interventions and guidance should be provided to patients, such as self-disclosure training and improving their perceived social support, in order to increase the rate of patients returning to work rate.

Objective:To investigate the prognostic value of proprotein convertase subtilisin/kexin type 9 (PCSK9) and blood lipid indexes in patients with sepsis.Methods:Patients with sepsis or septic shock who were ≥ 18 years old and met the Sepsis-3.0 diagnostic criteria admitted to the department of critical care medicine of Binzhou Medical University Hospital from January to October 2021 were enrolled. Healthy adults at the same period were selected as healthy control group. Baseline characteristics, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) score were recorded. Venous blood samples were collected within 24 hours after diagnosis, and serum PCSK9 was determined by enzyme-linked immunosorbent assay (ELISA) at 1, 3 days and 5 days. Meanwhile, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG) and lipoprotein A were detected. The differences of each index between sepsis group (28-day death group and survival group) and healthy control group were compared. Meanwhile, the indexes of patients with different severity and 28-day prognosis in sepsis group were compared. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of PCSK9 and blood lipid for the prognosis of sepsis. Multivariate Logistic regression was used to analyze the influencing factors for the prognosis of sepsis, and the Kaplan-Meier survival curve at 28th day was drawn.Results:There were 50 patients in sepsis group (including 19 patients with sepsis, 31 patients with septic shock) and 27 patients in healthy control group. In the sepsis group, 19 patients died and 31 patients survived within 28 days. The serum PCSK9 in the sepsis group was significantly higher than that in the healthy control group [μg/L: 223.09 (198.47, 250.82) vs. 188.00 (165.27, 214.90), P < 0.01], and HDL-C, LDL-C, TC and lipoprotein A were significantly lower than those in the healthy control group [HDL-C (mmol/L): 0.82±0.35 vs. 1.45±0.24, LDL-C (mmol/L): 1.53 (1.14, 2.47) vs. 2.89 (2.55, 3.19), TC (mmol/L): 2.03 (1.39, 2.84) vs. 4.24 (3.90, 4.71), lipoprotein A (g/L): 8.80 (5.66, 17.56) vs. 27.03 (14.79, 27.03), all P < 0.01]. PCSK9 in the sepsis death group was higher than that in the survival group [μg/L: 249.58 (214.90, 315.77) vs. 207.01 (181.50, 244.95), P < 0.01], and the HDL-C, LDL-C and TC were lower than those in the survival group [HDL-C (mmol/L): 0.64±0.35 vs. 0.93±0.30, LDL-C (mmol/L): 1.32±0.64 vs. 2.08±0.94, TC (mmol/L): 1.39 (1.01, 2.23) vs. 2.69 (1.72, 3.81), all P < 0.01]. With the progression of the disease, the PCSK9 in the sepsis death group and the survival group was significantly lower than that within 1 day of diagnosis (all P < 0.05). ROC curve analysis showed that PCSK9 had higher predictive value of 28-day death than HDL-C, LDL-C, TC [area under ROC curve (AUC) and 95% confidence interval (95% CI): 0.748 (0.611-0.885) vs. 0.710 (0.552-0.868), 0.721 (0.575-0.867), 0.702 (0.550-0.854)]. Multivariate Logistic regression analysis showed that PCSK9 was an independent risk factor affecting the 28-day prognosis of sepsis (β value was 1.014, P = 0.020). Kaplan-Meier survival curve analysis showed that when PCSK9 ≥ 208.97 μg/L, with the increase of PCSK9, the 28-day survival rate of sepsis patients decreased significantly. Conclusions:PCSK9, HDL-C, LDL-C and TC can all predict the 28-day prognosis of patients with sepsis. The prognostic value of PCSK9 is the highest. PCSK9 is an independent risk factor affecting the prognosis of sepsis. In the early stage of the disease, PCSK9 may have a good predictive value for the prognosis of sepsis. When PCSK9 ≥ 208.97 μg/L, the 28-day survival rate decreased significantly.

Objective:To observe the effects of estradiol on expression of plasma membrane Ca 2+-ATPase isoform 2 in inner ear of rats. Methods:Twenty-five Three-months-old female Sprague-Dawley rats were randomly and equally divided into five groups by random number table mathod,with five rats in each group. Animals in Sham group were sham-operated while others were bilateral ovariactmized. One month after modeling, the OVX groups were supplemented with estradiol (E2 group), progesterone (P group), estradiol and progesterone (E2+P group)and vehicle sesame oil (Veh group), while the Sham operation group (Sham group) was supplemented with vehicle sesame oil.All rats were sacrificed and otocysts were obtained immediately. Enzyme-linked immunosorbent assay was used to detect the changes in serum estradiol and progesterone levels of each group of rats before operation, before treatment and before sacrifice. Western blot and quantitative real-time polymerase chain reaction were used to detect the expression of total PMCA2 protein and mRNA in the inner ear of each group.Results:There was no significant difference in serum estradiol and progesterone levels among the five groups before operated( P>0.05). Before treatment, the serum estradiol and progesterone levels of rats in each group were significantly lower than those in Sham group ( P<0.05). The serum estradiol level in E2 group and E2+P group was not significantly different from that in Sham group ( P>0.05), while the serum estradiol level in P group and Veh group was significantly different from that in Sham group ( P<0.05). The level of progesterone in P group and E2+P group was higher than that in Sham group ( P<0.05), while the level of progesterone in Veh group and E2 group was lower than that in Sham group ( P<0.05). Protein and mRNA expression of PMCA2 in P and Veh groups were significantly decreased compared with that of Sham group ( P<0.05) while the expression levels underwent no significantly change in E2 and E2+P groups ( P<0.05). Conclusion:The decrease of serum estradiol level can reduce the expression of otolith regulatory protein PMCA2 in rats, and then affect otolith metabolism, which may be an important link of estrogen affecting otolith metabolism.

Objective:To evaluate the assistant role of manifestations under tracheoscopy in the diagnosis of invasive pulmonary aspergillosis (IPA) in severe patients.Methods:A retrospective study was conducted. The patients with suspected IPA admitted to intensive care unit (ICU) of Affiliated Hospital of Binzhou Medical College from January 2015 to December 2019 were enrolled. The diagnosis, clinical diagnosis and suspected diagnosis were made according to the grading criteria of Guidelines for the diagnosis and treatment of invasive fungal infection in severe patients (2007). Those who met the criteria were enrolled in the IPA group, and those who did not meet the criteria or other pathogens were enrolled in the non-IPA group. The general data of the patients were collected, and the changes of tracheal and bronchial mucosa under tracheal microscope before and after treatment were recorded, as well as the results of galactomannan (GM) test and aetiology culture of bronchoalveolar lavage fluid (BALF). The baseline, bronchoscopy and pulmonary CT manifestations and their dynamic changes were compared in each group. Results:A total of 142 patients with suspected IPA were finally enrolled. Among them, 12 were pathologically proven IPA, 77 were probable IPA, 22 were possible IPA, and 31 were undefined IPA. Of the 142 patients, 60 had typical manifestations of mucosal injury under bronchoscopy, including 7 proven IPA patients (58.3%), 52 probable IPA patients (67.5%), and 1 possible IPA patient (4.5%), but none undefined IPA patient. The patients undergoing lung CT scan were 12 proven IPA patients (100%), 73 probable IPA patients (94.8%), and 21 possible IPA patients (95.5%), respectively. Most of the Chest CT showed patchy or strip density increasing and other non-specific manifestations. There were 3 proven IPA patients (25.0%), 7 probable IPA patients (9.0%), and 0 possible IPA patient (0%) who had typical IPA CT manifestations (halo sign and cavity or crescent sign). Among the patients of proven IPA and probable IPA (89 cases), there were a total of 35 cases with endoscopic airway mucosal injury and tracheoscopy reexamination ≥ 3 times. All the 35 patients received anti-aspergillus treatment, among which 16 survived and 19 died. Among the 16 patients who survived, the microscopic appearance of mucosal injury was gradually reduced and the clinical manifestations were gradually improved. Of the 19 patients who died, 16 had deteriorated endoscopic airway mucosal injury.Conclusions:The specific manifestations of severe patients with bronchial mucosal injury are of great significance in the diagnosis of IPA. In the case of severe patients who cannot receive pathological examination or chest CT in time, dynamic observation of the changes of airway mucosal injury is a simple auxiliary method to discover the changes of patients' condition in time, evaluate the effect of antifungal therapy and the prognosis of IPA.

Objective:To explore the value of high mobility group box 1 (HMGB1), von Willebrand factor (vWF) and other cytokines in predicting the severity and prognosis of sepsis patients.Methods:Patients with sepsis and septic shock who ≥18 years old and met the Sepsis-3 diagnostic criteria admitted to the department of critical care medicine of Binzhou Medical University Hospital from January to June 2019 were taken as the research objects. The healthy individuals for regular health examination in the same period were taken as the control. The basic information, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and sequential organ failure assessment (SOFA) scores were recorded. The venous blood was taken within 24 hours after the patients were diagnosed. The levels of HMGB1, vWF, tumour necrosis factor-α (TNF-α), interleukin-10 (IL-10), soluble thrombomodulin (sTM), vascular endothelial growth factor receptor 2 (VEGFR-2), angiopoetin-2 (Ang-2) and other cytokines in serum were determined by enzyme linked immunosorbent assay (ELISA). Differences among patients with sepsis, septic shock, healthy physical examinees, and patients who died in 28-day and those who survived, were compared. Spearman rank correlation method was used to analyze the correlation among each cytokine and APACHEⅡ, SOFA scores. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of cytokines on the prognosis of patients with sepsis/septic shock. Logistic regression was used to analyze the risk factors of 28-day death.Results:Eleven patients with sepsis, 25 patients with septic shock and 30 healthy individuals were enrolled. Among the patients with sepsis/septic shock, 15 died in 28-day and 21 survived. The serum levels of TNF-α, IL-10, HMGB1, vWF, sTM and VEGFR-2 in patients with sepsis were significantly higher than those in the healthy control group. The levels of TNF-α, IL-10, HMGB1, vWF, sTM in septic shock group were higher than those in the sepsis group, while the Ang-2 level decreased significantly. The serum levels of TNF-α, IL-10, HMGB1, vWF and sTM in the death group were higher than those in the survival group, while Ang-2 was lower than the survival group. Spearman correlation analysis showed that HMGB1, TNF-α, sTM, IL-10, vWF were positively correlated with APACHEⅡ score when patients with sepsis/septic shock were enrolled ( r values were 0.652, 0.666, 0.445, 0.430 and 0.355, respectively, all P < 0.05), and HMGB1, TNF-α also positively correlated with SOFA score ( r values were 0.433, 0.479, both P < 0.05). Ang-2 was negatively correlated with APACHEⅡ and SOFA scores ( r values were -0.519, -0.440, both P < 0.05). ROC curve analysis showed that the predictive value of HMGB1, vWF, IL-10, sTM for 28-day death in patients with sepsis/septic shock were higher than the APACHEⅡ score [the area under ROC curve (AUC) and 95% confidence interval (95% CI): 0.946 (0.870-1.000), 0.902 (0.790-1.000), 0.877 (0.745-1.000), 0.868 (0.734-1.000) vs. 0.846 (0.700-0.991)]. Logistic regression analysis showed that APACHEⅡ score, vWF, sTM, and IL-10 were independent risk factors for 28-day death in patients with sepsis/septic shock (β values were 4.731, 0.407, -7.058, -0.887, all P < 0.05). Conclusion:HMGB1, vWF, IL-10, sTM and other cytokines all can be used to evaluate the severity and prognosis of sepsis patients.
