ABSTRACT

Objective: To investigate the feasibility of endoscopic lateral neck dissection via the breast and transoral approaches (ELNDBTOA) for papillary thyroid carcinoma (PTC). Methods: From February 2015 to April 2019, 10 patients with PTC (cN1b) including 1 male and 9 females aged from 22 to 53 years old received ELNDBTOA in the General Surgery Department of Zhongshan Hospital, Xiamen University. Total thyroidectomy, the central lymph node dissection and the selective neck dissection (levels Ⅱ, Ⅲ and Ⅳ) were performed endoscopically via the breast approach, and then the residual lymph nodes were dissected via transoral approach. The medical records, operation time, blood loss, complications and postoperative follow-up outcomes were analyzed retrospectively. SPSS 22.0 software package was used for statistical processing of clinical data of patients. Results: All cases were successfully treated with ELNDBTOA without transfer to open surgery. The average operative time was (362.5±79.7) min, the blood loss was (23.0±14.9) ml, and the postoperative hospital stay was (5.1±1.3) days. The mean number of harvested cervical lymph nodes were (34.2±25.8), and the mean number of positive lymph nodes were (6.5±4.9). Lymph nodes were dissected by the further dissection via oral approach in 6 patients and a total of 9 lateral lymph nodes were havested from 2 of the 6 patients, with 3 positive lymph nodes. Two patients had transient skin numbness in the mandibular area and recovered within two weeks. One patient developed transient hypoparathyroidism and recovered within two months. No secondary bleeding, recurrent laryngeal nerve paralysis, chylous leakage, neck infection, permanent hypoparathyroidism or other complications were observed. The follow-up time was from 16 to 66 months with a median of 42.5 months, no tumor recurrence or metastasis occurred, and also no obvious deformity, abnormal sensation or movement in the chest, neck and mouth was observed. Conclusions: ELNBTOA is safe and feasible, with good cosmetic outcome.

ABSTRACT

<b>Objective::To study whether Sanhuang Xiexintang (SHXXT) can restore endothelial function by inhibiting the activation of NOD-like receptor protein 3 (NIRP3) induced by 7-ketocholesterol (7-keto) in vascular endothelial cells. <b>Method::The aortic rings of mice were cultured in normal group, model (7-keto) group, SHXXT groups (1%, 2% and 5% drug-containing serum). Vasodilation function of mice was observed. Microvascular endothelial cells were cultured according to the above experimental groups, and NIRP3 inhibitor isoglycyrrhizin (ISO) group, was also set. Western blot was used to detect the expressions of endothelial nitric oxide synthase (eNOS), NIRP3, cysteinyl aspartate specific proteinase-1 (Caspase-1), interleukin-1<italic>β</italic> (IL-1<italic>β</italic>) protein. In addition, nitric oxide (NO) quantitative kit was used to detect the concentration of NO. <b>Result::Compared with the normal group, the endothelium-dependent vasodilation function of vascular rings was significantly reduced in model group (<italic>P</italic><0.01), and the drug group significantly restored the endothelium-dependent vasodilation function in a concentration-dependent manner (<italic>P</italic><0.05, <italic>P</italic><0.01). Meanwhile, microvascular endothelial cells were also studied. Compared with the normal group, the content of eNOS protein in the model group decreased (<italic>P</italic><0.05), while the concentration of NO decreased significantly (<italic>P</italic><0.01). After treatment with SHXXT serum, eNOS and NO could be restored, with significant differences in the concentration of NO with 5% (<italic>P</italic><0.05) and 10% (<italic>P</italic><0.01) SHXXT serum. At the same time, the expressions of NIRP3 (<italic>P</italic><0.05), cle-Caspase-1 activation (<italic>P</italic><0.01) and IL-1<italic>β</italic> production (<italic>P</italic><0.01) in endothelium were significantly increased under 7-keto stimulation, and the SHXXT serum could significantly inhibit the expression and activation of relevant proteins. Subsequently, endothelial cells were treated with NIRP3 inhibitor ISO. Compared with the model group, eNOS expression increased, and NO concentration increased significantly (<italic>P</italic><0.01) after treatment with ISO, but ISO had no synergistic effect on SHXXT serum. <b>Conclusion::SHXXT can improve endothelium-dependent vascular dysfunction induced by 7-keto, which is achieved by NO signaling pathway mediated by inhibiting the activation of endothelial NIRP3-related proteins.

ABSTRACT

Objective To investigate the association between epicardial adipose thickness(EAT)and coronary artery plaque vulnerability evaluated by intravascular ultrasound(IVUS)in patients with coronary heart disease.Methods A retrospective case-control study was conducted.A total of 261 patients who were diagnosed with coronary heart disease via coronary angiography from August 2014 to March 2017 were enrolled in this study.Patients were divided into an acute coronary syndrome(ACS)group(n=92)and a stable angina pectoris(SAP)group(n=169).EAT and coronary artery plaque vulnerability evaluated by IVUS were compared between the two groups.The correlation between EAT and coronary artery plaque vulnerability was analyzed.Results EAT was greater in the ACS group than in the SAP group(5.4 ± 1.1)mm vs.(2.9±0.7) mm,t =12.664,P<0.01).The plaque burden,the rates of soft plaque detection and the rates of spotty calcification detection were higher in the ACS group than in the SAP group(67.8±8.0)% vs.(57.4 ± 10.4) %,35.9% or 33/92 vs.18.9% or 32/169,0.4 % or 28/92 vs.17.8% or 30/169,all P <0.05),while there was no significant difference in luminal area between the two groups(P =0.772).The proportion of positive remodeling was higher in the ACS group than in the SAP group(35.9% or 33/92 vs.8.3% or 14/169,P<0.01).Linear regression analysis showed that EAT was correlated with plaque burden(r =0.592,P <0.01),lumen area(r =-0.273,P <0.01) and reconstruction index(r =0.447,P <0.01).Conclusions Epicardial adipose thickness is correlated to coronary artery plaque vulnerability evaluated by IVUS.

ABSTRACT

Objective To investigate the association between epicedial adipose thickness (EAT)and coronary artery in-stent restenosis (ISR).Methods 617 patients underwent review of coronary angiography in one year of drug-eluting stent implantation in our hospital from October 2013 to October 2015 were enrolled in the study.According to the angiography resluts,patients were divided into ISR group and control group.All cases recieved ultrasonic analysis of epicardial adipose thickness and biochemical test.The correlation of EAT,biochemical concentrations and ISR were determined.Results The EAT in ISR group was significantly higher than that in the control group [(7.78 ± 1.32) mm vs (4.19 ± 0.57) mm,t =22.998,P < 0.001].It was also found that the family history of premature coronary artery disease and the severity of coronary artery lessions based on Syntax scores in the IRS group were higher than those in normal control group.Biochemical tests showed that plasma levels of triglycerides and glycosylated hemoglobin were higher,including plasma homocysteine and hypersensitive C-reactive protein (P < 0.05).Multivariates logistic regression analysis suggested that the EAT was associated with ISR [Exp(B) =0.001,P =0.004].Moreover,one-way linear regression showed that EAT was correlated with the severity of IRS (r =0.891,P <0.001).Conclusions Epicardial adipose thickness was correlated with the occurrence and severity of coronary artery in-stent restenosis.

ABSTRACT

Objective: To analyze the clinical features of hemorrhage after colon polypectomy with endoscopic mucosal resection (EMR) in order to provide guidance for prevention of postoperative bleeding. Methods: We reviewed 922 cases of colon polypectomy with EMR in the Gastroenterological Department of the Sixth Medical Center of Chinese PLA General Hospital during January 1, 2016 to May 1, 2018. According to whether postoperative bleeding happened, cases were classified as bleeding group (37 cases) and non-bleeding group (885 cases), and a comparative analysis of general data, combined disease, polyp conditions and EMR operation was performed in the two groups. Results: The proportion of long-term smoking in the bleeding group (37.8%) was significantly higher than that in the non-bleeding group (18.8%, P<0.05). The proportion of patients with hypertension, diabetes, cardiovascular disease, chronic liver disease or chronic kidney disease in the bleeding group was not significantly different from the non-bleeding group. The proportion of patients with polyps located in multiple intestine segments (35.1%) was higher in the bleeding group than that in the non-bleeding group (18.2%, P<0.05). The number of resections, maximum basal diameter and mean basal diameter [1.81 ± 1.08, (0.95 ± 0.35) cm, (0.83 ± 0.31) cm] were significantly higher than those in the non-bleeding group [1.43 ± 0.85, (0.76 ± 0.27) cm, (0.71 ± 0.23) cm, P<0.05]. The proportions of titanium clips with sparse coverage, incomplete coverage, and lodging (40.5%, 43.2%, 48.7%) in hemorrhage group were significantly higher than those in the non-bleeding group (11.2%, 10.1%, 22.3%, P<0.05). Logistic regression analysis showed that long term smoking, maximum basal diameter of polyps, sparse titanium clip, incomplete coverage, and lodging were independent risk factors for delayed hemorrhage after EMR. Conclusion: In the patients with long-term smoking, large diameter of polyp basement or poor sealing of titanium clips, the wound is prone to bleeding after EMR. Titanium clip sealing is an important measure to prevent delayed bleeding.

ABSTRACT

Objective To investigate the clinical treatment and outcomes of severe community-acquired pneumonia (CAP) complicated with mediastinal emphysema after renal transplantation. Methods Clinical data of9 patients with severe CAP complicated with mediastinal emphysema after renal transplantation were retrospectively analyzed. The acute physiology and chronic health evaluationⅡ(APACHEⅡ) and oxygenation index were recorded when the patients were admitted to the intensive care unit (ICU). The complications of mediastinal emphysema and corresponding treatment were observed. The treatment course during the ICU, mortality rate in ICU, ICU stay time and hospital stay time were recorded. All patients underwent pathogenic examinations. Results The APACHEⅡ score of9 patients with severe CAP complicated with mediastinal emphysema after renal transplantation was 14 (8-21) scores and the oxygenation index was 150 (133-189) mmHg. Among 9 patients, 3 cases were infected by bacteria alone, 3 cases were infected by bacterial infection combined with viral infection, 1 case was infected by mycobacterium tuberculosis complicated with other bacterial infection and 1 case was viral infection. No pathogenic evidence was detected in the remaining 1 patient. Mediastinal emphysema complicated with subcutaneous emphysema occurred in 7 cases and pneumothorax occurred in 6 cases. Treatment methods included anti-infection, modified immunosuppressive program, mediastinal drainage, thoracic closed drainage, subcutaneous incision and extracorporeal membrane oxygenation (ECMO) treatment. Six patients received invasive mechanical ventilation (IMV), 2 received non-invasive positive pressure ventilation (NIV) and 1 received high-flow nasal oxygen cannula (HFNC). Among 9 patients, the mortality rate in ICU was 6/9, the remaining 3 patients were recovered and discharged, the ICU stay time was 26 (17-40) d, and the total hospital stay time was 27-61 d. Conclusions Mediastinal emphysema is a serious complication of patients presenting with severe CAP after renal transplantation with a high mortality rate. For these patients, imaging evaluation, timely drainage and full sedation should be strengthened, and ECMO treatment should be delivered when necessary.

ABSTRACT

Objective To explore the association between BMI and the risk of developing cardiac surgery associated acute kidney injury (CS-AKI),mortality of AKI and AKI requiring renal replacement therapy (AKI-RRT) after cardiac surgery.Methods Clinical data of patients undergoing cardiac surgery from January 2011 to December 2015 in Zhongshan Hospital of Fudan University were prospectively collected.Patients were divided into four groups according to BMI classification of Chinese population.Adjustment for selection bias was further assessed using propensity score method (PSM) to evaluate the role of BMI in the development of AKI.Results A total of 8442 patients were enrolled,among which 1092 patients successfully matched through PSM.The AKI incidences were respectively 30.3%,33.3%,38.6% and 46.8% in four BMI groups (P < 0.01) before PSM.The AKI incidences were respectively 31.9%,35.2%,42.5% and 42.9% in four BMI groups (P=0.016) after PSM.The risk of developing AKI increased by 19.9% as the BMI increased per 5 kg/m2 (95% CI:1.070-1.344,P=0.002).The hospital mortality of patient (overall,AKI,AKI-RRT) in four groups was not statistically different after PSM (P > 0.05),but overweight group always had the lowest mortality.Conclusions BMI is a risk factor for AKI after cardiac surgery,and the AKI incidence increases with increasing BMI in a certain range.

ABSTRACT

Objective To study the incidence,possible risk factors,and influence on patient outcomes of diaphragmatic dysfunction in patients after surgical treatment of type A aortic dissection using ultrasound.Methods Patients who received replacement of hemiarch or total arch with concomitant procedures concerning aortic pathology,and an elephant trunk procedure for the descending aorta were prospectively enrolled in this study from February to May 2017.After surgery,they were transferred to the cardiac surgical intensive care unit.They were divided into two groups based on diaphragmatic excursion:diaphragmatic dysfunction (DD) group and diaphragmatic function normal (DN) grouBilateral diaphragmatic excursions were evaluated using ultrasound during spontaneous breathing trial by T-tube.The differences in demographic characteristics,operation-related variables and outcomes were compared between the two groups.Results A total of 42 patients were enrolled in this study,and 32 of them suffered from diaphragmatic dysfunctions.Compared with DN group,the excursion of the influenced diaphragm in DD group was significantly reduced[(0.450 ± 0.331)cm vs.(1.801 ± 0.616)cm,P<0.01],while the excursion of the non-influenced diaphragm was not reduced[(2.013±0.655)cm vs.(1.801 ±0.616) cm,P=0.254].Diaphragmatic thickness was comparable [(0.184±0.028)cm vs.(0.189±0.028)cm,P=0.559 ] between the two groups while thickening fraction was significantly reduced in DD group[(4.67%±3.63)% vs.(23.58%±10.69)%,P<0.01].Meanwhile,respiratory rate was significantly higher in DD group as compared to DN group [(24.13 ± 4.98)times/min vs.(20.50 ± 3.17)times/min,P=0.037].Patients in DD group showed longer cross-clamp duration[(121.78±27.75)min vs.(93.10±18.84)min,P=0.004] and longer cardiopulmonary bypass duration [(208.09±32.78)min vs.(182.70±24.38)min,P=0.03] than patients in DN grouFurthermore,binary logistic analysis indicated that longer cross-clamp duration was the potential risk factor for diaphragmatic dysfunction after type A aortic dissection surgery.Mechanical ventilation duration was longer in DD group than in DN group (88 h vs.37 h,P=0.194) but without statistical significance.The usage of noninvasive ventilation was significantly increased in DD group as compared to DN group (46.88% vs.10%,P=0.036).Other outcomes such as post-operative complications,mortality,ICU length of stay were comparable between the two groups.Conclusions Diaphragmatic dysfunction was very common after surgical treatment of type A aortic dissection.Longer duration of cross-clamp was considered as a potential risk factor of diaphragmatic dysfunction.A sequential management of noninvasive ventilation after extubation was feasible for diaphragmatic dysfunction after surgical treatment of type A aortic dissection.

ABSTRACT

<p><b>BACKGROUND</b>In cardiac surgery, elevation of procalcitonin (PCT) could be observed postoperatively in the absence of any evidence of infection and also seems to be a prognostic marker. PCT levels measured in patients undergoing Type A aortic dissection (TAAD) were used to determine prognostic values for complications and surgical outcomes.</p><p><b>METHODS</b>Measurements of PCT, C-reactive protein (CRP), and leukocyte count were observed in TAAD surgery patients (n = 251; average age: 49.02 ± 12.83 years; 78.5% male) at presurgery (T0) and 24 h (T1), 48 h (T2), and 7 days (T3) postsurgery. PCT clearance (PCTc) on days 2 and 7 was calculated: (PCTday1- PCTday2/day7)/PCTday1 × 100%. Endotracheal intubation duration, length of stay (LOS) in the Intensive Care Unit (ICU)/hospital, and complications were recorded.</p><p><b>RESULTS</b>PCT peaked 24 h postsurgery (median 2.73 ng/ml) before decreasing. Correlation existed between PCT levels at T1 and duration of cardiopulmonary bypass (P = 0.001, r = 0.278). Serum PCT concentrations were significantly higher in nonsurvivor and multiple organ dysfunction syndrome groups on all postoperative days. PCT levels at T1 correlated with length of time of ventilation support and ICU/hospital LOS. Comparing PCT values of survivors versus nonsurvivors, a PCT cutoff level of 5.86 ng/ml at T2 had high sensitivity (70.6%) and specificity (74.3%) in predicting in-hospital death. PCTc-day 2 and 7 were significantly higher in survivor compared with nonsurvivor patients (38% vs. 8%, P= 0.012, 83% vs. -39%, P< 0.001). A PCTc-day 7 cutoff point of 48.7% predicted survival with high sensitivity (77.8%) and specificity (81.8%).</p><p><b>CONCLUSIONS</b>PCT level and PCTc after TAAD surgery might serve as early prognostic markers to predict postoperative outcome. PCT measurement may help identify high-risk patients.</p>

ABSTRACT

Objective To investigate the efficacy of dexmedetomidine on sedation in post-cardiac surgery patients with NIV intolerance.The changes of respiratory function and hemodynamics of the patients as well as non-invasive ventilation (NIV) failure rate were also under evaluation.Methods Thirty-five post-cardiac surgery patients with NIV intolerance and hypoxemia were enrolled in this prospective study.All patients were sedated with dexmedetomidine.NIV was standardized according to the uniform protocol.The main outcome was NIV success (avoiding endotracheal intubation) or NIV failure (requiring endotracheal intubation or die).The cardiorespiratory parameters (BP,HtR and RR) and artery blood gas analysis were prospectively recorded before and after sedation.The respiratory function and hemodynamics changes in both groups (NIV success group and NIV failure group) were then evaluated.Factors independently associated with NIV failure were identified using a logistic regression model.Results Twenty out of 35 patients (57.14%) survived while 15 (42.86%) patients failed NIV.After 1 h and 4 h of NIV with dexmedetomidine sedation,respiratory rate in both groups were decreased compared with baseline,especially in NIV success group.The PaO2/FiO2 was also improved after 1h and 4h of NIV treatment compared with baseline.The improvement was more significantly in NIV success group.The heart rate was decreased compared with baseline with no differences between two groups.There were no significant changes on PaCO2 and mean arterial pressure (MAP) during the treatment.The respiratory and hemodynamics variables identified as predictors of NIV failure were included in a multivariate logistic regression.RR > 23 time/min (OR =3.2,95% CI:2.043 ~ 4.301,P < 0.01) 1 h after NIV,RR > 20 time/min (OR =2.1,95% CI:1.659~3.231,P=0.025) 4 h after NIV,PaO2/FiO2 <178 mmHg (OR=2.4,95%CI:1.892 ~ 3.287,P <0.01) 1 h after NIV and PaO2/FiO2 < 185 mmHg (OR =1.7,95% CI:1.243 ~ 2.365,P =0.041) 4 h after NIV independendy predicted NIV failure.Conclusions Dexmedetomidine might be considered as an effective and safe sedative for post-cardiac surgery patients with NIV intolerance.Early identification of predictors of NIV failure may facilitate early intervention.

ABSTRACT

Objective To evaluate the prognostic value of blood lactate (Lac) level in sepsis patients with or without diabetes.Methods 106 patients admitted to intensive care unit (ICU) of Zhongshan Hospital Affiliated to Fudan University from April 2015 to November 2016 were enrolled. The patients with age > 18 years and the length of hospital stay > 24 hours were included. Records including blood Lac, serum creatinine (SCr), white blood cell count (WBC), platelet count (PLT), sequential organ failure assessment (SOFA) on the first day of admission; minimum oxygen index (PaO2/FiO2) in 3 days after admission; mechanical ventilation, whether there was a history of diabetes, usage of biguanides, etiology control treatment, usage of continuous renal replacement therapy (CRRT) were collected. According to the level of blood Lac patients were divided into high Lac group (Lac > 2 mmol/L) and low Lac group (Lac ≤ 2 mmol/L);based on their diabetic history, sepsis patients were divided into the diabetes group and non-diabetes group. The survival curve of each group was analyzed by Kaplan-Meier regression analysis, and the factors influencing the prognosis were analyzed by multivariate Cox regression analysis.Results There were 76 males and 30 females sepsis patients, with an average age of (68.1±14.7) years old. In the 51 patients of low Lac group, there were 7 patients who suffered from diabetes. While in the 55 patients of high Lac group, there were 12 patients who suffered from diabetes. Compared with low Lac group, high Lac group had a higher age, higher SOFA score, and a lower proportion of patients who had the treatment of etiology control (allP 0.05). Kaplan-Meier survival curve analysis showed that the 90-day survival rate in the high Lac group was significantly lower than that in the low Lac group (56.36% vs. 90.20%,χ2 = 0.697,P = 0.008). The high Lac group without diabetes had lower survival rate, and the 90-day survival rate was significantly lower than that of the low Lac group without diabetes (58.14% vs. 90.90%,χ2 = 7.152,P = 0.007); there was no significant difference in 90-day survival rate between the high Lac group and the low Lac group with diabetes (50.00% vs. 85.71%,χ2 = 0.012,P = 0.914). Multivariate Cox regression analysis showed that blood Lac was an independent risk factor for the prognosis of sepsis patients [odds ratio (OR) = 3.863, 95% confidence interval (95%CI) = 1.237-12.060,P = 0.020]. After stratification according to their diabetic history, the blood Lac was an independent risk factor for the prognosis of sepsis patients without diabetes (OR = 4.816, 95%CI = 1.407-15.824, P = 0.010), but the blood Lac had no effect on the prognosis of sepsis patients with diabetes (OR = 0.000, 95%CI =0.000-1.103,P = 0.270).Conclusions The predictive value of blood Lac on sepsis patients with or without diabetes was different. The blood Lac was related with the prognosis of sepsis patients without diabetes, while further study should be conducted for the prognostic value of blood Lac in sepsis patients with diabetes, and it's possible to increase the cut-off-point of Lac level in these patients.

ABSTRACT

<p><b>BACKGROUND</b>Acute kidney injury (AKI) is considered as a common and significant complication following abdominal aortic aneurysm (AAA) repair. This study aimed to assess the associated risk factors of AKI in the critically ill patients undergoing AAA repair and to evaluate the appropriate AKI management in the specific population.</p><p><b>METHODS</b>We retrospectively examined data from all critically ill patients undergoing AAA repairs at our institution from April 2007 to March 2012. Multivariable analysis was used to identify factors associated with postoperative AKI, which was defined by risk, injury, failure, loss and end-stage (RIFLE) kidney disease criteria. The goal-directed hemodynamic optimization (maintenance of optimal hemodynamics and neutral or negative fluid balance) and renal outcomes were also reviewed.</p><p><b>RESULTS</b>Of the 71 patients enrolled, 32 (45.1%) developed AKI, with 30 (93.8%) cases diagnosed on admission to surgical intensive care unit (SICU). Risk factors for AKI were ruptured AAA (odds ratio (OR) = 5.846, 95% confidence interval (CI): 1.346 - 25.390), intraoperative hypotension (OR = 6.008, 95%CI: 1.176 to 30.683), and perioperative blood transfusion (OR = 4.611, 95%CI: 1.307 - 16.276). Goal-directed hemodynamic optimization resulted in 75.0% complete and 18.8% partial renal recovery. Overall in-hospital mortality was 2.8%. AKI was associated with significantly increased length of stay ((136.9 ± 24.5) hours vs. (70.4 ± 11.3) hours) in Surgical Intensive Care Unit.</p><p><b>CONCLUSIONS</b>Critically ill patients undergoing AAA repair have a high incidence of AKI, which can be early recognized by RIFLE criteria. Rupture, hypotension, and blood transfusion are the significant associated risk factors. Application of goal-directed hemodynamic optimization in this cohort appeared to be effective in improving renal outcome.</p>

ABSTRACT

<p><b>BACKGROUND</b>The prognostic power of n-terminal pro-brain natriuretic peptide (NT-proBNP) in sepsis is disputable and unstable among different models. We attempt to evaluate the prognostic potential of NT-proBNP in combination with the sequential organ failure assessment (SOFA) score in sepsis.</p><p><b>METHODS</b>In this retrospective study, 100 consecutive sepsis patients were enrolled. Clinical data such as admission SOFA, the Acute Physiologic and Chronic Health Evaluation score, shock prevalence, use of lung protective ventilation, vasopressors, and glucocorticoids were recorded. Additionally, serum creatinine (Scr1 and Scr3) and NT-proBNP (NT-proBNP1 and NT-proBNP3) were assayed and evaluated at admission and on day 3 respectively.</p><p><b>RESULTS</b>DNT-proBNP (NT-proBNP3 minus NT-proBNP1) (P < 0.001, Hazard ratio (HR) = 1.245, 95% confidence interval (CI), 1.137 - 1.362) and admission SOFA (P < 0.001, HR = 1.197, 95%CI, 1.106 - 1.295) were independently related to in-hospital mortality. Their combination was a more robust predictor for in-hospital mortality than either of them individually. Patients with high DNT-proBNP and SOFA had the poorest prognosis.</p><p><b>CONCLUSIONS</b>In our study, both DNT-proBNP and SOFA were independent predictors of septic patients' prognosis. Moreover, the combination of DNT-proBNP and admission SOFA provided a novel strategy that contained information regarding both the response to treatment and sepsis severity.</p>

ABSTRACT

Antithymocyte globulin (ATG) has long been used for immune-induction and anti-rejection treatments for solid organ transplantations. To date, few cases of ATG-induced acute respiratory distress syndrome (ARDS) have been published. Here, we present a case of ARDS caused by a single low-dose of ATG in a renal transplant recipient and the subsequent treatments administered. Although the patient suffered from ARDS and delayed graft function, he was successfully treated. We emphasize that the presence of such complications should be considered when unexplained respiratory distress occurs. Early use of corticosteroids, adjustment of immunosuppressive regimens, and conservative fluid management, as well as empiric antimicrobial therapies, may be effective strategies for the treatment of ARDS caused by ATG.

ABSTRACT

<p><b>OBJECTIVE</b>To find an appropriate feature representation in the biclustering of symptom-herb relationship in Chinese medicine (CM).</p><p><b>METHODS</b>Four different representation schemes were tested in identifying the complex relationship between symptoms and herbs using a biclustering algorithm on an insomnia data set. These representation schemes were effective count, binary value, relative success ratio, or modified relative success ratio. The comparison of the schemes was made on the number and size of biclusters with respect to different threshold values.</p><p><b>RESULTS AND CONCLUSIONS</b>The modified relative success ratio scheme was the most appropriate feature representation among the four tested. Some of the biclusters selected from this representation scheme were known to follow the therapeutic principles of CM, while others may offer clues for further clinical investigations.</p>

ABSTRACT

We designed an adjustable simulated lung for clinical use. Depending on the feature of adjustable resistance and compliance, the device could simulate various pathological changes of lung, such as obstructive diseases and restrictive diseases. Thru simulating various pathological conditions with the device, the clinicians could learn how to manipulate a mechanical ventilator. In addition, the device has a leakage equipment for simulating leakage of respiratory circuit, depending on which the clinicians could learn more about ventilators.
