This article analyzed the medical records of two patients with Vibrio vulnificus primary sepsis who were admitted to the First Affiliated Hospital of Naval Medical University and reviewed the latest literature. On November 6, 2019, a 54-year-old male patient was admitted to the hospital. The patient's lower limbs were red, swollen, and painful with ecchymosis and hemorrhagic bullae after he ate freshwater products. The emergency fasciotomy was performed 3 h after admission, and the multiple organ failure occurred after operation. The patient was given up treatment 24 h after admission. On August 12, 2020, a 73-year-old male patient was admitted to the hospital. He was in shock state on admission and had hemorrhagic bullae on his right lower limb after he ate seafood. At 3 h post admission, he underwent emergency surgical exploration and amputation of right thigh. Six days later, he received negative pressure wound treatment on the stump. On the 13^th day post admission, his families forgo the active treatment and he died 15 d after admission. The two cases were both failed to be diagnosed at the first time, and the disease progressed rapidly. Necrotizing fasciitis and multiple organ failure occurred. After the diagnosis was confirmed, timely fasciotomy and high amputation were performed respectively. The microbiological examinations both reported Vibrio vulnificus. Although the 2 cases were not cured successfully, the course of disease and some indexes of patient with early amputation were better than those of patients with fasciotomy. Vibrio vulnificus is widely distributed and frequently detected in fresh water products. The pathogenic pathway is fuzzy and complex, and it is easy to be misdiagnosed. It is necessary to establish the treatment process of Vibrio vulnificus sepsis. Early and aggressive surgical intervention should be carried out as soon as possible, fasciotomy and debridement should be thorough, and the patients with hemorrhagic bullae should be amputated early. Postoperative comprehensive measures are also important for improving the survival rate of patients.

The 2019 novel coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has occurred in China and around the world. SARS-CoV-2-infected patients with severe pneumonia rapidly develop acute respiratory distress syndrome (ARDS) and die of multiple organ failure. Despite advances in supportive care approaches, ARDS is still associated with high mortality and morbidity. Mesenchymal stem cell (MSC)-based therapy may be an potential alternative strategy for treating ARDS by targeting the various pathophysiological events of ARDS. By releasing a variety of paracrine factors and extracellular vesicles, MSC can exert anti-inflammatory, anti-apoptotic, anti-microbial, and pro-angiogenic effects, promote bacterial and alveolar fluid clearance, disrupt the pulmonary endothelial and epithelial cell damage, eventually avoiding the lung and distal organ injuries to rescue patients with ARDS. An increasing number of experimental animal studies and early clinical studies verify the safety and efficacy of MSC therapy in ARDS. Since low cell engraftment and survival in lung limit MSC therapeutic potentials, several strategies have been developed to enhance their engraftment in the lung and their intrinsic, therapeutic properties. Here, we provide a comprehensive review of the mechanisms and optimization of MSC therapy in ARDS and highlighted the potentials and possible barriers of MSC therapy for COVID-19 patients with ARDS.

Cholangitis and cholecystitis are intra-abdominal infections that show poor prognosis upon progression to sepsis and multiorgan failure. Administration of antibiotics with high antimicrobial susceptibility and removal of infected bile at the initial treatment are important. After undergoing ERCP for diagnostic purposes, a 58-year-old man developed acute cholangitis and cholecystitis accompanied by rhabdomyolysis, multi-organ failure, and severe sepsis. Broad-spectrum antibiotics with bedside endoscopic nasobiliary drainage were administered, but clinical symptoms did not improve. Therefore, bedside EUS-guided transgastric gallbladder aspiration and lavage was performed, resulting in successful treatment of the patient. We report the above described case along with a discussion of relevant literature.

OBJECTIVETo observe the morphological changes in enteric nerve system (ENS) of rats with multiple organ dysfunction syndrome (MODS) treated by Dachengqi Decoction (, DCQD).

METHODSFifty Wistar rats were randomly assigned to the control group, MODS model group and DCQD treated group. The rats in MODS model group and DCQD treated group were injected Escherichia coli (E. coli) suspension into abdominal cavity under sterile condition. The DCQD treated group was gavaged with DCQD 2 days before the E. coli suspension was injected. Twenty-four hours after injection, the proximal segment of intestine was resected and studied by immunohistofluorescence using vesicular acetylcholine transporter, vasoactive intestinal polypeptide (VIP), substance P (SP) and neuronal nitric oxide synthase (nNOS) antibodies. The whole-mount preparations were observed by laser scanning confocal microscope to detect the changes of quantity and fluorescence integral optical density (IOD) value of intestine enteric nerves.

RESULTSCompared with the control group, the quantity and IOD value of acetylcholine (ACh), VIP, SP and nitric oxide (NO) nerves of intestine in the MODS group were significantly decreased (P<0.01), and the network of enteric nerves was remarkably disrupted. Compared with the MODS group, the quantity and fluorescence IOD value of ACh, VIP, SP and NO nerves in the DCQD group were significantly increased (P<0.01), and the network of enteric nerves was remarkably recovered.

CONCLUSIONDCQD can protect and repair damage in the network of ACh, SP, NO and VIP nerves in rats with MODS, which may be one of mechanisms involved in promoting gastrointestinal motility by DCQD.

BACKGROUNDElderly multiple organ dysfunction syndrome (MODS) patients receiving invasive mechanical ventilation have poor prognosis in intensive care units (ICUs). We studied the usefulness of four commonly used severity scores and extrapulmonary factors that affected weaning to predict outcome of such patients.

METHODSClinical data of 197 patients on admission to ICUs (from January 2009 to June 2012) were used retrospectively. The Acute Physiology and Chronic Health Evaluation (APACHE) II, APACHE III, Sample Acute Physiological Score (SAPS) II and MODS scores were calculated. All the patients were grouped into survivors and nonsurvivors according to the prognosis. Patients, who weaned from ventilator (n = 154), were subdivided into a successful weaning group and a failed weaning group. The receiver operating characteristic (ROC) curves and Logistic regression was used for prognostic and weaning assessment.

RESULTSBased on the outcomes, the areas under the ROC of APACHE II, APACHE III, SAPS II, and MODS were 0.837, 0.833, 0.824, and 0.837, respectively. The Logistic regression analysis revealed that the odds ratio (OR) of underlying lung diseases, serum albumin and creatinine, and the number of organ failures was 2.374, 0.920, 1.003, and 1.547. APACHE II scores on admission performed excellent (ROC: 0.921) on the weaning assessments.

CONCLUSIONSAPACHE II and MODS systems were marginally better for evaluating the prognosis of elderly MODS patients who received invasive mechanical ventilation. Underlying lung diseases, serum albumin, serum creatinine and the number of organ failures were independent prognostic factors. Using the APACHE II scores on admission before weaning may increase the likelihood of successful weaning. (ClinicalTrial.gov identifier NCT01802983).

OBJECTIVETo study the early effects of ulinastatin (UTI) by aerosol inhalation on rabbits with acute lung injury induced by LPS, and to observe the early diagnostic value of 320-slice CT.

METHODSAccording to the random number table, 18 specific pathogen free New Zealand white rabbits were divided into normal control group, group LPS, and group UTI, with 6 rabbits in each group. Rabbits in group LPS and group UTI were given 15 mL lipopolysaccharide (0.16 mg/mL, in the dose of 0.8 mg/kg) to reproduce acute lung injury model. Rabbits in normal control group were given equal volume of normal saline. Rabbits in UTI group were treated with UTI by aerosol inhalation for 10 min from 30 min after injury, while those in the other two groups received normal saline by aerosol inhalation. Rabbits in group LPS and group UTI were scanned by 320-slice CT at post injury hour (PIH) 6 and 24. After anesthesia, heart blood of rabbits in group LPS and group UTI was collected for determination of serum levels of TNF-α, IL-1β, and IL-6 by ELISA at PBH 24. At PBH 24, lung tissue samples were harvested for gross observation and histomorphological observation, measurement of wet to dry weight ratio, and detection of mRNA expressions of TNF-α, IL-1β, and IL-6 with RT-PCR. Above-mentioned indexes were detected in rabbits of normal control group at the same time point. Data were processed with one-way analysis of variance and LSD test.

RESULTS(1) CT perfusion (CTP) image. The difference in CTP image of rabbits in group LPS between PBH 6 and PBH 24 was obvious, while that of rabbits in group UTI and normal control group was slight and not obvious respectively. (2) There were statistically significant differences in the serum levels of TNF-α, IL-1β, and IL-6 of rabbits among the three groups (with F values from 843.896 to 2 564.336, P values below 0.001). The serum levels of TNF-α, IL-1β, and IL-6 in group UTI were respectively (225 ± 9), (190 ± 8), (227 ± 6) pg/mL, and they were significantly lower than those in group LPS [(710 ± 25), (306 ± 16), (422 ± 16) pg/mL, with P values below 0.001]. (3) Gross observation. In group UTI, the degrees of pulmonary edema and pneumorrhagia of rabbits were lower than those in group LSP. (4) Histological observation. The damage to alveolar wall in group UTI was milder, and alveolar space hemorrhage and inflammatory cell infiltration were significantly less intense as compared with those in group LPS. (5) Compared with that in normal control group, the wet to dry weight ratio of lung tissue was increased in group LPS (P < 0.001). The wet to dry weight ratio of lung tissue in group UTI was significantly higher than that in normal control group but lower than that in group LPS (P values below 0.001). (6) There were statistically significant differences in mRNA levels of TNF-α, IL-1β, and IL-6 in lung tissue of rabbits among three groups (with F values from 24.700 to 69.538, P values below 0.001). The mRNA levels of TNF-α, IL-1β, and IL-6 in lung tissue of rabbits in group UTI were respectively (31.4 ± 2.7), (21.2 ± 3.3), (13.9 ± 2.4) pg/mL, which were significantly lower than those in group LPS [ (58.5 ± 10.0) , (35.1 ± 5.1), (20.7 ± 3.2) pg/mL, P values below 0.001].

CONCLUSIONSUTI by aerosol inhalation can mitigate pulmonary edema and hemorrhage and inhibit inflammatory response. 320-slice CT may be used for detection of early lung injury.

OBJECTIVETo observe the effects and mechanisms of Xuebijing Injection (XI) on multiple organ dysfunction syndrome (MODS) patients.

METHODSRecruited were 76 MODS patients at ICU, Zhejiang Provincial Quhua Hospital from February 2009 to September 2011. They were randomly assigned to the control group (36 cases) and the treatment group (40 cases). All patients received conventional treatment. Those in the treatment group were intravenously injected with XI (prepared by adding 100 mL QI in 100 mL normal saline), twice daily for seven successive days. The APACHE II score, SOFA score, serum procalcitonin (PCT), tumor necrosis factor-alpha (TNF-alpha), interleukin 6 (IL-6) and 10 (IL-10) of the two groups were observed in the two groups before treatment, at 3 days and 7days after treatment. The ICU stay time and the 28-day mortality were compared between the two groups.

RESULTSAfter seven days of treatment, the APACHE II score, SOFA score, TNF-alpha, IL-6, IL-10, and PCT significantly decreased in the treatment group, showing statistical difference when compared with the control group at the same time point (P < 0.05). The 28-day mortality, the ICU stay time, APACHE II score, and SOFA score decreased more significantly in the treatment group than in the control group, showing statistical difference (P < 0.05).

CONCLUSIONXI could significantly reduce the ICU stay time of MODS patients, and its mechanisms might be correlated to regulating inflammatory reactions.

OBJECTIVETo analyze the variation of serum insulin levels in critically ill children and investigate the underlying mechanism and clinical significance to provide the basis for treatment.

METHODTotally 332 critically ill children admitted in pediatric intensive care unit (PICU) of Hunan Children's Hospital from Nov., 2011 to April, 2012 were studied. The high insulin group (n = 332) was defined as insulin levels within 24 h > 11.1 mU/L and was divided into 2 groups: mildly elevated group (n = 194): 11.10 - 33.30 mU/L, increased three times group (n = 138): > 33.3 mU/L. Insulin, C-peptide and blood glucose were measured within 24 hours after admission, on day 3 and 7. Other results of inflammatory markers, lactate, cardiac enzymes, amylase, pancreatic ultrasound, hepatic and renal function as well as indicators related to severity and prognosis were recorded after admission.

RESULTThe peak of insulin level was seen on day 1, then presented a downward trend and reached the normal level on day 7. The peaks of blood glucose and C-peptide level were seen on day 1 then declined, the levels on day 7 were still slightly higher than normal level. The insulin level on admission (41.47 ± 30.85) mU/L were positively correlated with lactic acid (2.29 ± 1.81) mmol/L and procalcitonin level (5.08 ± 6.70) ng/ml (r = 0.370, P = 0.000; r = 0.168, P = 0.002) (P < 0.01). The insulin level on admission in children with 1 organ failure (41.24 ± 22.60) mU/L or 2 or multiple organ failure (48.98 ± 22.17) mU/L was higher than that in children with non-organ failure (34.11 ± 29.84) mU/L (U = 1621.001, P = 0.000;U = 1300.000, P = 0.000) (P < 0.01). The insulin level on admission in death group (52.99 ± 32.34) mU/L was higher than that in survival group (32.85 ± 24.10) mU/L (U = 1585.000, P = 0.000) (P < 0.01). Ten cases in death group were complicated with pancreatic damage and the average insulin level on admission was (65.29 ± 50.53) mU/L.

CONCLUSIONThe high insulin level was correlated with the degree of inflammatory response, ischemia and hypoxia. The high insulin level in critically ill children was relevant to the pancreatic damage, the severity of the disease, organ dysfunction, and evaluation of prognosis.

BACKGROUND/AIMS: Intra-abdominal hypertension (IAH) is being increasingly reported in patients with severe acute pancreatitis (SAP) with worsened outcomes. The present study was undertaken to evaluate intra-abdominal pressure (IAP) as a marker of severity in the entire spectrum of acute pancreatitis and to ascertain the relationship between IAP and development of complications in patients with SAP. METHODS: IAP was measured via the transvesical route by measurements performed at admission, once after controlling pain and then every 4 hours. Data were collected on the length of the hospital stay, the development of systemic inflammatory response syndrome (SIRS), multiorgan failure, the extent of necrosis, the presence of infection, pleural effusion, and mortality. RESULTS: In total, 40 patients were enrolled and followed up for 30 days. The development of IAH was exclusively associated with SAP with an APACHE II score > or =8 and/or persistent SIRS, identifying all patients who were going to develop abdominal compartment syndrome (ACS). The presence of ACS was associated with a significantly increased extent of pancreatic necrosis, multiple organ failure, and mortality. The mean admission IAP value did not differ significantly from the value obtained after pain control or the maximum IAP measured in the first 5 days. CONCLUSIONS: IAH is reliable marker of severe disease, and patients who manifest organ failure, persistent SIRS, or an Acute Physiology and Chronic health Evaluation II score > or =8 should be offered IAP surveillance. Severe pancreatitis is not a homogenous entity.
