ABSTRACT
Acute respiratory distress syndrome (ARDS) is a clinical syndrome caused by a variety of internal and external injury factors in the lung, and its morbidity and mortality have remained stubbornly high. Recent studies have shown that endothelial-derived extracellular vesicles are an important mediator of pathological signal transduction and play an important regulatory role in the occurrence, development and prognosis of ARDS. Now our paper reviewed the regulatory mechanism of endothelial-derived extracellular vesicles in ARDS.
ABSTRACT
Objective:Sepsis patients usually have a fever, but it is still controversial about whether sepsis patients with fever need cooling treatment. This study aimed to evaluate the effect of external physical cooling on the prognosis of sepsis patients.Methods:This study was a single-center, open-label, randomized clinical trial. Adult sepsis patients with body temperature above 38.3 °C admitted to the Critical Care Medicine of Northern Jiangsu People's Hospital from June 2020 to December 2020 were selected, and randomly assigned in a 1∶1 ratio to the cooling group and control group. Patients in the cooling group used external physical cooling methods to reduce their core body temperature to the normal range (36.5-37.5°C) within 4 h of enrollment and maintained for 48 h. Standard care was implemented in the control group at all times, and all antipyretic treatments were prohibited. The 28-day mortality, 72 h-Δ sequential organ failure assessment (SOFA) score (SOFA score at enrollment–SOFA score after 72 h), length of hospital stay and length of ICU stay were compared between the two groups.Results:A total of 53 patients (32 males and 21 females) were enrolled in the study, including 26 patients in the cooling group and 27 patients in the control group. There were no statistical differences in age, sex, source of infection, SOFA score and body temperature between the two groups (all P>0.05). There was no significant difference in the 28-day mortality between the cooling group and the control group ( RR=1.38, 95% CI: 0.62-3.07, P=0.430). The 72 h-ΔSOFA score of the cooling group was significantly higher than that of the control group, the mean difference between the two groups was 1.90 (95% CI: 0.09-3.71, P=0.040), and there was no significant difference in length of hospital stay, length of ICU stay and 28-day mortality between the two groups. Conclusions:External physical cooling management can not significantly reduce the 28-day mortality of sepsis patients. However, external physical cooling can reduce the 72-h SOFA score in sepsis patients, and improve the organ function of patients.
ABSTRACT
Objective:To investigate the effect of the completion time of initial 30 mL/kg fluid resuscitation on the prognosis of patients with septic shock.Methods:An observational study was conducted. The inpatients with septic shock admitted to intensive care unit (ICU) of Northern Jiangsu People's Hospital, Affiliated Hospital of Yangzhou University and Jiangdu People's Hospital from October 1st, 2018 to September 30th, 2020 were enrolled. The general data including gender, age, body mass index (BMI), patient source, site of infection, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score and arterial blood lactic acid (Lac) at ICU admission, fluid resuscitation dose, completion time of initial 30 mL/kg fluid resuscitation, mechanical ventilation, incidence of acute kidney injury (AKI), continuous renal replacement therapy (CRRT), length of ICU stay and 28-day mortality. The relationship between the completion time of initial 30 mL/kg fluid resuscitation and ΔSOFA score (the difference between SOFA score 3 hours of fluid resuscitation and initial SOFA score) was analyzed. In addition, according to the completion time (T) of initial 30 mL/kg fluid resuscitation, the patients were divided into T ≤ 1 hour group, 1 hour < T≤2 hours group, 2 hours < T≤3 hours group and T > 3 hours group, and the observation parameters among the groups were compared.Results:① A total of 131 patients were enrolled, including 94 males and 37 females with an average age of (68.3±15.0) years old. The median APACHE Ⅱ score was 27 (21, 34), the median of initial SOFA score was 12 (10, 14), the median of initial Lac was 5.0 (3.4, 7.1) mmol/L, and the most common source of infection was lung, with a total of 87 patients (66.41%). The completion time of initial 30 mL/kg fluid resuscitation and ΔSOFA score fitted the Logistic curve ( Y = -1.062 6 X2+4.407 9 X+0.961 8), which suggested that the early or late completion time of initial fluid resuscitation had adverse effects on the prognosis of patients with septic shock.② There was no significant difference in infection site, initial APACHE Ⅱ score, initial Lac, and initial SOFA score among different completion time of initial 30 mL/kg fluid resuscitation groups. The respiratory support rate, the incidence of AKI and the ratio of CRRT in the T ≤1 hour group were significantly higher than those in the 1 hour < T≤2 hours group, 2 hours < T≤3 hours group and T > 3 hours group (respiratory support rate: 78.57% vs. 75.51%, 42.86%, 75.00%; incidence of AKI: 57.14% vs. 20.41%, 21.43%, 50.00%; ratio of CRRT: 35.71% vs. 0%, 7.14%, 16.67%), the differences among the groups were statistically significant (all P < 0.05). The 28-day mortality was the highest in the T ≤ 1 hour group (64.29%), and the lowest in the 1 hour < T ≤2 hours group (22.45%), 35.71% in the 2 hours < T ≤ 3 hours group, 33.33% in the T > 3 hours, and the difference among the groups was statistically significant ( P < 0.01). Conclusions:Completion of initial 30 mL/kg fluid resuscitation in 1-2 hours after septic shock may reduce the 28-day mortality and improve organ dysfunction, and initial fluid resuscitation prematurely or too late may increase 28-day mortality. But further research and verification are needed.
ABSTRACT
Objective To analyze the multimodal imaging findings of nonspecific granulomatous prostatitis (NSGP)and improve our understanding of the disease.Methods 1 427 patients underwent transrectal ultrasoundGguided prostate biopsies in our department,then 1 3 nodules in 11 patients were proven NSGP by pathology,of which 3 nodules were in inner gland and 10 were in outer gland.The characteristics of these nodules on MRI,transrectal ultrasound elastography (TRE)and contrastGenhanced ultrasonography (CEUS)were retrospectively analyzed. Results MRI:All of the nodules showed similar performances:hypointensity on T1 WI and T2 WI,low ADC and high signal on DWI (highGbGvalue),early enhancement and faded fast or slow,depressed citrate (Cit)and relatively elevated choline (Cho)peak.TRE:The cutGoff point of strain ratio (SR)was determined as 5.97 to diagnose prostate cancer and the SRs of 8 nodules were greater than 5.9 7.CEUS:1 1 nodules showed early enhancement and great intensity,but the rest of nodules showed same performance with normal tissue.Conclusion The multimodal imaging helps to improve the understanding of NSGP and plays a positive role in guiding targeted biopsy.Moreover,the operators could lessen the number of needle punctures properly according to the multimodal imaging findings, which would reduce the risk of puncture complications on patients.

ABSTRACT
Objective To discuss the neuroimaging characteristics of transcranial ultrasound in Parkinson's disease (PD) patients with or without depression.Methods Transcranial sonography (TCS) was performed in PD patients with depression (PDD +,n =50),PD patients without depression (PDD-,n =50),depression patients (D,n =50) and healthy controls (n =50),who were enrolled in the Second Affiliated Hospital of Soochow University from September 2010 to July 2016.The differences of the neuroimaging characteristics of TCS in brainstem raphe (BR) and substantia nigra (SN) in four groups were analyzed.According to the degree of depression,PDD + and D groups were divided into three subgroups:mild,moderate and severe depression,and the differences of echo characteristics in BR were analyzed among the subgroups.Results The rate of abnormal BR echogenicity was significantly higher in PDD + (78.0％,39/50) and D (82.0％,41/50) groups than that in PDD-(18.0％,9/50) and healthy control (10.0％,5/50) groups (x2 =87.80,P ＜0.01),and there was no statistically significant difference among the subgroups (PDD + group,P =0.98;D group,P =0.57).The rate of SN hyperechogenicity was significantly higher in PDD + (80.0％,40/50) and PDD-(86.0％,43/50) groups than that in D (8.0％,4/50) and healthy control (10.0％,5/50) groups (x2 =110.07,P＜ 0.01).Conclusion The echogenicity changes of BR and SN on TCS could provide some useful neuroimaging information for the diagnosis and differential diagnosis of PDD-from PDD +.
ABSTRACT
Objective To evaluate the value of transrectal real-time tissue elastography (RTE) targeted prostate biopsy in the peripheral zone combined with peak strain index.Methods One hundred and forty-one patients with suspicious prostate lesions in the peripheral zone were evaluated from February 2011 to February 2014.All the patients underwent RTE with a mean age of 71.6 years,PSA of 30 ng/ml,prostate volume of 50.3 ml and measured peak strain index (PSI).The diagnostic value of PSI was assessed by receiver operating characteristic (ROC) curve.Two-core RTE combined with PSI targeted prostate biopsy was taken and subsequently a 10-core systematic biopsy was taken.The value of RTE was evaluated.The data of targeted biopsy and systematic biopsy in prostate were both reviewed and statistically compared.Results Cancer was detected in 72 of 141 patients (PSI,mean 24.79),and 69 patients had benign prostate disease (PSI,mean 3.02).PSI value of prostate cancer was significantly higher than that of the benign lesions (P ＜ 0.05).Prostate cancer could be predicted with the highest sensitivity (87.5％) and specificity (88.6％) using the cutoff value of PSI ≥ 5.97 with an area under the curve of 0.95.RTE targeted biopsy combined with PSI could detect 95.6％ of moderate or high risk prostate cancer.One hundred and fifty-nine suspicious areas detected by RTE in 141 patients were biopsied with 2 cores for each area.The positive incidence of prostate cancer in RTE-targeted biopsy cores was 44％ and in systematic biopsy was 30.2％ (P ＜ 0.05).Among the 72 prostate cancer patients,63 cases (87.5％) were detected by RTE-targeted biopsy,62 cases (86.1％) by systematic biopsy (P ＞ 0.05).Conclusions RTE combined PSI can improve the detection rate of prostate cancer in the peripheral zone and likewise guide targeted biopsy combined with svstematic biopsy to detect more moderate or high risk prostate cancer.
