Objective:To investigate whether stress hyperglycemia (SH) is an independent risk factor for the occurrence and mortality of sepsis-associated encephalopathy (SAE).Methods:From August 2016 to October 2021, sepsis patients admitted to the ICU of Guangdong Provincial People's Hospital were selected as the study subjects. According to whether they developed to SH (RBG>11.1 mmol/L) within 7 days of enrollment, the pat ients were divided into the SH group and the non-SH group for analysis. Logistic regression was used to analyze whether SH was an independent risk factor for SAE occurrence, and ROC curve was used to analyze the predictive value of SH to SAE. Kaplan-Meier curve was used to compare the 90-day survival of SAE patients with or without SH. Cox regression analysis was used to analyze the risk factors of 28-day and 90-day death in SAE patients.Results:A total of 183 sepsis patients were included, including 62 patients in the SH group and 121 in the non-SH group. Logistic regression analysis demonstrated that SH was an independent risk factor for SAE ( OR=4.452, 95% CI: 2.021-9.808, P <0.001). ROC curve demonstrated that SH could accurately predict SAE (AUC=0.831; Sensitivity=78.4%; Specificity=76.8%; and Yoden index=0.553). Kaplan-Meier curve demonstrated that the 90-day survival of SAE patients with SH significantly declined (log-rank test: P<0.01). Cox regression analysis suggested that SH was a risk factor for death at day 28 and day 90 in SAE patients (28 d, HR=2.272, 95% CI: 1.212-4.260, P=0.010; 90 d, HR=2.456, 95% CI: 1.400-4.306, P<0.01). Conclusions:SH is an independent risk factor for SAE and can predict SAE occurrence. SH significantly reduces 90-day survival and increase mortality at 28 and 90 days in SAE patients.

Objective:To investigate the diagnostic and early-warning value of laboratory test indicators for sepsis-induced myocardial injury (SIMD).Methods:The clinical data of 183 patients with sepsis admitted to the Department of Emergency and Critical Care Medicine of Guangdong Provincial People's Hospital from August 2016 to October 2020 were collected. The patient's age, gender, past medical history, vital signs and pathogen culture results were extracted. Cardiac function, blood routine, liver function, renal function, inflammatory factors, coagulation function, APACHE Ⅱ and SOFA scores were recorded at enrollment and 72 h after admission. SIMD was defined as cTnT ≥300 pg/mL and NT-proBNP ≥1243 pg/mL twice in 72 h intervals between enrolled cases, and the early-warning factors of patients with SIMD were analyzed. The differences in various indicators between the two groups were compared, and Logistic regression analysis was used to explore the diagnostic efficacy of cTnT and NT-proBNP combined for SIMD, and the correlation between PCT/PLT ratio and the occurrence of SIMD.Results:Among 250 patients, 67 patients were excluded for lack of the main indicators, and 183 patients (including 62 patients with history of cardiac disease) were enrolled finally. Among 183 patients with sepsis, 105 patients (57.38%) with cTNT ≥300 pg/mL and NT-proBNP ≥1 243 pg/mL, were diagnosed as myocardial injury; after excluding 62 patients with history of cardiac disease, 59 patients (48.76%) with cTNT ≥300 pg/mL and NT-proBNP ≥1 243 pg/mL were diagnosed as myocardial injury. Logistic regression analysis showed that increased PCT/PLT ratio ( OR=1.585, 95% CI: 1.124-2.237, P=0.009) was an independent risk factor for early-warning of SIMD. The PCT/PLT ratio ( OR= 1.850, 95% CI: 1.103-3.102, P=0.020) could stably predict the occurrence of SIMD in patients without previous history of heart disease. ROC curve analysis showed that PCT/PLT ratio could effectively predict the occurrence of SIMD (AUC=0.693, 95% CI: 0.617-0.769, P<0.001), the optimal cut-off value was 0.177 (sensitivity: 65.7%, specificity: 66.7%). The PCT/PLT ratio was still effective in predicting the occurrence of SIMD after excluding patients with previous history of heart disease (AUC=0.733, 95% CI: 0.643-0.823, P<0.001), and the optimal cut-off value was 0.429 (sensitivity: 55.9%, specificity: 83.9%). Conclusions:The combination of cTnT and NT-proBNP has certain diagnostic value for SIMD, and the PCT/PLT ratio could warn the occurrence of SIMD.

Objective:To evaluate the predictive effect of sepsis-induced coagulopathy (SIC) score level on the prognosis of septic patients under sepsis 3.0 criteria.Methods:A retrospective single-center observational study was conducted on the septic patients admitted to the department of critical care medicine and the department of emergency in Guangdong Provincial People's Hospital from August 2016 to July 2021. The baseline data, laboratory indexes and SIC scores of the patients were collected on the first and fourth (4th) day after hospitalization. Whether the patients were survival within 30 days after enrollment was recorded. Univariate and multivariate Logistic regression were used to analyze the independent risk factors for 30-day mortality in septic patients. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of SIC score on the 30-day prognosis of septic patients.Results:A total of 173 patients met the inclusion criteria including 111 (64%) survivors and 62 (36%) non-survivors. There were significant differences in lymphocyte count (LYM), sequential organ failure assessment (SOFA), oxygenation index (PaO 2/FiO 2) and cardiovascular SOFA score between the survival group and the non-survival group. And there were no significant differences in other indexes. On the first day of admission, there were statistically significant differences in PaO 2/FiO 2, cardiovascular SOFA score, LYM, SIC score between the non-survival group and the survival group. There were significant differences in international normalized ratio (INR), prothrombin activity (PTA), prothrombin time (PT), PaO 2/FiO 2, cardiovascular SOFA score, LYM, C-reactive protein (CRP) and procalcitonin (PCT) between the two groups on the 4th day after admission. The mortality of septic patients increased with the increase of SIC score. Binary Logistic regression analysis showed that SIC score and LYM on the 4th day after admission were independent risk factors for 30-day mortality in septic patients (both P < 0.05). The ROC curve showed that SIC score had a certain predictive value for the 30-day prognosis of septic patients [area under the ROC curve (AUC) = 0.712, 95% confidence interval (95% CI) was 0.629-0.794, P < 0.001]. The predictive value of SIC score combined with LYM was better than that of the two alone (AUC = 0.748, 95% CI was 0.688-0.828, P < 0.001). Conclusions:The SIC score has a certain predictive value for the 30-day prognosis of septic patients. The predictive value of SIC score combined with LYM is better than that of the two alone, which is expected to be a potential indicator for early assessment of the condition and prognosis of septic patients.

OBJECTIVE: To assess the predictors and outcomes of acute kidney injury (AKI) among patients with coronavirus disease 2019 (COVID-19). OBJECTIVE: This retrospective observational study was conducted among patients with a confirmed diagnosis of COVID-19 admitted to Hankou Hospital between January, 5 and March 8, 2020. We evaluated the association of AKI with the demographic and biochemical parameters and clinical outcomes of the patients using univariate regression analysis. OBJECTIVE: Atotal of 287 COVID-19 patients, including 55 with AKI and 232 without AKI, were included in the analysis. Compared with the patients without AKI, the patients with AKI were older, predominantly male, and were more likely to have hypoxia and pre-existing hypertension and cerebrovascular diseases. The patients with AKI also had higher levels of white blood cells, D-dimer, aspartate aminotransferase, total bilirubin, creatine kinase, lactate dehydrogenase, procalcitonin, C-reactive protein, a higher prevalence of hyperkalemia, lower lymphocyte counts, and higher chest computed tomographic scores. The incidence of stage 1 AKI was 14.3% and that of stage 2 or 3 AKI was 4.9%. The patients with AKI had much higher mortality rate than those without AKI. OBJECTIVE AKI is an important complication of COVID-19. An older age, a male gender, multiple pre- existing comorbidities, lymphopenia, increased infection indicators, elevated D-dimer, and impaired heart and liver functions are all potential risk factors ofAKI. COVID- 19 patients with AKI that progresses into stages 2 or 3 AKI have a high mortality rate. Prevention of AKI and monitoring kidney function is critical in the care of COVID-19 patients.

Objective:To investigate the clinical characteristics and prognosis of the patients with nocardiosis.Methods:From January 2013 to July 2019, 44 patients with nocardiosis in Department of Infectious Diseases, Huashan Hospital, Fudan University in Shanghai were enrolled, and their clinical data were retrospectively analyzed, including baseline characteristics, clinical manifestations, underlying diseases history of glucocorticoid therapy, laboratory data (blood routine examination, procalcitonin, C-reactive protein, lymphocytes subsets, etc.), imaging changes, bacterial strain identification, treatment regimens and outcomes. According to the locations of infection, patients were divided into pulmonary nocardiosis, extrapulmonary single-organ nocardiosis and disseminated nocardiosis. The Mann-Whitney U test was used for comparison between two groups, and the Kruskal-Wallis H test was used for comparison among multiple groups. Results:Among the 44 cases of nocardiosis, 14 cases were pulmonary nocardiosis, 17 cases were extrapulmonary single-organ nocardiosis (including nine cases with central nervous system infection, six cases with skin and soft tissue infection, one case with abdominal abscess and one case with urinary tract infection) and 13 cases were disseminated nocardiosis (including four cases with bloodstream infection, six cases with central nervous system and lung or skin and soft tissue infection, three cases of lung and skin and soft tissue infection). Thirty-four cases had underlying diseases, and 27 cases received glucocorticoid or immunosuppressant treatment. The main symptom of 11 patients in pulmonary nocardiosis group was productive cough, while that of the patients in other two groups was fever. Nocardia species were mainly Nocardia brasiliensis, Nocardia nova and Nocardia farcinicaia. The white blood cell counts and neutrophils proportion were normal or slightly increased in 42 cases, and the platelets were normal or slightly decreased in 41 cases. Erythrocyte sedimentation rate increased in 19 cases, procalcitonin increased in 21 cases, C-reactive protein increased in 34 cases, and ferritin increased in 18 cases. A total of 34 patients were tested for lymphocyte subsets, of which 15 had CD4 + T lymphocytes decreased, 14 had CD8 + T lymphocytes increased, seven had B lymphocytes increased, seven had B lymphocytes decreased, and eight had natural killer cells decreased. The hemoglobin of patients with pulmonary nocardiosis was higher than that of patients with extrapulmonary infection, and the difference was statistically significant ( U=0.095, P=0.025). The imaging manifestations were mainly abscess and inflammatory exudation. Forty cases were cured or improved, one case was still on treatment, and three cases died. Conclusions:The clinical manifestations of nocardiosis involving various organs are non-specific. Standardized treatment could reduce the mortality of nocardiosis.

In order to explore the effect of extract (SNE) on skin wound healing in mice and its mechanism, hemostasis effect of SNE was measured, the mouse skin wound model was established by full-thickness excision. The morphological changes of the wound were observed after the treatment with SNE and the healing rate was measured. The changes of wound histology were observed by hematoxylin eosin (HE) staining, Masson staining and transmission electron microscope (TEM). The expression of cell factors and related proteins was detected by quantitative real-time polymerase chain reaction (qRT-PCR). Results showed that the SNE possessed hemostatic function. SNE could obviously improve the healing rate of wound in mouse and shorten time of scab removal compared with the none-treatment (NT) group ( < 0.05).The pathological histology analysis results showed complete epidermal regeneration, with remarkable capillary and collagen fiber observed in the SNE group. The expression level of tumor necrosis factor-α (TNF -α), interleukin-1β (IL-1β) and transforming growth factor-β1 (TGF-β1) in SNE group was significantly lower than that of the NT group on 7 d ( < 0.05). Moreover, compared with the NT group, the gene expressions level of Smad7 was significantly increased and the level of type II TGF-β receptors (TGF-βRII), collagen I (COL1A1) and α-smooth muscle actin (α-SMA) were significantly reduced in the SNE group on 28 d ( < 0.05), but the difference was not statistically significant compared to Yunnanbaiyao group (PC group) ( > 0.05). These results indicated that SNE possessed obvious activity of accelerating wound healing and inhibiting scar formation, and its mechanism was closely related to hemostatic function, regulation of inflammatory factors, collagen deposition, collagen fiber remodeling and intervening TGF-β/Smads signal pathway. Therefore, SNE may have promising clinical applications in skin wound repair and scar inhibition.

Objective: To analyze the survival time of people living with HIV/AIDS and related influencing factors in Sichuan province during 1991-2017. Methods: A retrospective cohort study was conducted to analyze the data of 143 988 HIV/AIDS cases. The data were collected from Chinese HIV/AIDS Comprehensive Information Management System. Life table method was used to calculate the survival proportion of the cases, and Cox proportion hazard regression model was used to identify the factors related with survival time. Results: Among 143 988 HIV/AIDS cases a total of 30 420 cases died of AIDS related diseases (21.1%) and the average survival time was 11.51 years (95%CI: 11.39-11.64). Multivariate Cox regression analysis showed that the influencing factors for the survival of HIV/AIDS cases were gender (male vs. female, HR=1.35, 95%CI: 1.32-1.40), education level (primary school or below vs. junior middle school: HR=1.15, 95%CI: 1.12-1.18), ethnic group (Han vs. other ethnic groups, HR=1.46, 95%CI: 1.41-1.52), occupation (farmer vs. other occupations: HR=1.26, 95%CI: 1.22-1.29), age (≥55 years old vs. 15-24 years old: HR=3.18, 95%CI: 3.02- 3.36), disease phase (AIDS vs. HIV infection: HR=1.44, 95%CI: 1.39-1.48), antiretroviral therapy (ART) (receiving ART vs. receiving no ART: HR=0.20, 95%CI: 0.19-0.20), and CD₄⁺T cell counts at diagnosis (>500 cells/μl vs.<200 cells/μl: HR=0.42, 95%CI: 0.40-0.45). Conclusions The average survival time of HIV/AIDS cases was 11.51 years in Sichuan during 1991- 2017. The risk factors for the survival of the cases were male, education level of primary school or below, Han ethnic group, farmer, old age at diagnosis, disease phase, The protective factors for the survival of HIV/AIDS cases were receiving ART and higher CD₄⁺ T cell counts at diagnosis.

Objective To determine the effect of high dose albumin on permeability of blood brain barrier (BBB) in brain of rats after ischemic-reperfusion (IR) in order to explore its possible mechanism.Methods Establishment of brain ischemic reperfusion rat model by using middle cerebral artery occlusion (MCAO).Medicine treatment was given by caudal vein injection after 2 hours of MCAO.Thirty-six healthy male SD rats were then randomly (random number) divided into 6 groups (n =6 in each):6 h and 24 h sham-operation groups (Group Sham:operation without ischemia),6 h and 24 h normal saline groups (Group NS:NS injection 5 ml/kg) and 6 h and 24 h albumin group (Group Alb:25 ％ Alb injection 1.25 g/kg).Six hours and 24 hours after the end of reperfusion,rats were measured by Zea-Longa score (neural function deficit) separately.Serum concentration of S100B was examined by the ELISA kit and Evans blue in brain tissue was detected by spectrophotometer.The level of AQP4 was examined by Western blot and immunohistochemistry.All data were analyzed by one-way analysis of variance (ANOVA),The intergroup comparisons were analyzed by the least-significant-difference (LSD) test by using SPSS version 17.0 software.Differences were considered statistically significant if P ＜ 0.05.Results Zea-Longa score significantly increased in both group NS and group Alb at 6 h and 24 h (P =0.000).However,there was no significant difference in ZEA-LONGA score of 6 h and 24 h between group Alb and group NS (P =1.000).The serum concentration of S100B in group NS 6 h was significantly lower than that in group Alb at 6h (196.67±20.11 vs 160.04±14.00,P=0.000),and at24h (2.45±0.07 vs.2.23±0.07,P=0.000).Furthermore,concentration of Evans blue in brain tissue in group Alb was significantly higher than that in group NS at both 6 h (0.97 ± 0.08 vs.0.74 ± 0.06,P =0.000) and 24 h (2.45 ± 0.07 vs.2.23 ± 0.07,P =0.000).The expression of AQP4 in brain tissue was higher in group Alb than that in group NS at both 6 h (0.72 ±.0.11 vs.0.57 ± 0.06,P ＜ 0.01) and 24 h (0.80 ± 0.03 vs 0.61 ± 0.02,P ＜0.01).Conclusions High dose albumin contribute slightly in improvement of neural deficit in rats after IR.On the contrary,it can also aggravate the IR injury,which increases brain edema then increase the permeability of BBB.The mechanism may be associated with over-expression of AQP4 in brain tissue.
