Objective To explore the factors that could affect plasma level of D-dimmer test in acute aortic syn-drome. Methods Blood samples (2 mL) from acute aortic syndrome patients (n=76) obtained immediately after admission to detect D-dimmer using ELISA. Blood routine test and biochemical indicators tests including creatinine were also performed. White blood cell (WBC), serum value of creatinine, aortic contrast-enhanced CT, incidence of Shock and death were all re-corded. The receiver-operating characteristic curve (ROC) was established to assess the potency of D-dimmer to predict hospital mortality. Results According to ROC analysis, the optimal cut-off value of D-dimmer to predict hospital mortality was >2 988.6 μg/L (FEU), with 86.7% sensitivity and 70.5% specificity. The patients were divided into group A (D-dim-mer<2 988.6μg/L FEU, n=45) and group B (D-dimmer≥2 988.6μg/L FEU,n=31). Onset timing was longer in group A than that in group B(P<0.01). Involvement of ascending aorta was less common in group A than in group B(P<0.05). Aortic intramural hematoma was less common in group A than in group B(P<0.05). Logistic analysis demonstrated that short time of onset, involvement of ascending aorta, non-aortic intramural hematoma were all independent factors of higher D-dimmer (≥2 988.6μg/L FEU). Conclusion Patients with long time of onset, without involvement of ascending aorta, with intramural hematoma are liable to have lower values of plasma D-dimmer.

Objective To evaluate the effectiveness of renal sympathetic denervation (RDN) for hypertensive heart dis-ease combined with systolic heart failure. Methods Two patients (mean age 35 years) with hypertensive heart disease com-bined with systolic heart failure on maximal tolerated heart failure therapy underwent bilateral renal denervation. Echocar-diography, the six minute walk distance, renal function, glycosylated hemoglobin and NT-proBNP were assessed at baseline and 1 year after renal denervation. Results Renal artery angiography showed that no stenosis and dissection. After 1 year follow up, the left ventricular ejection fraction (LVEF), six minute walk distance and NT-proBNP were significantly im-proved, and the size of left ventricular decreased. Conclusion RDN is effective and feasible for the treatment in patients with hypertensive heart disease and systolic heart failure.

Objective To investigate the clinical therapeutic effects of lung protective ventilation and sequential recruitment maneuver (RM) on treatment of patients with severe acute pancreatitis (SAP) complicated with acute respiratory distress syndrome (ARDS). Methods Sixty patients with SAP complicated with ARDS admitted to the Department of Critical Care Medicine of the First Affiliated Hospital of Nanchang University from April 2014 to March 2016 were enrolled. They were divided into control group and experimental group by random number table, 30 patients in each group. On the basis of comprehensive treatment, the patients in control group were treated with lung protective ventilation mode: low tidal volume ventilation (6 mL/kg) + optimal end-expiratory positive pressure (PEEP) ventilation mode, when the intra-abdominal pressure (IAP) was essentially returned to a normal level (Ⅰ grade intra-abdominal hypertension), the patients in experimental group were treated by the combination with RM therapy, and the rest treatment was the same as the control group. Under the two types of ventilation strategies, the clinical effects, respiratory mechanics, hemodynamics and arterial blood gas indexes were compared between the two groups. Results The mechanical ventilation time (days: 13.82±4.40 vs. 19.87±7.40), the length of ICU stay (days:22.67±4.40 vs. 26.43±5.39) and incidence of ventilator associated pneumonia [VAP: 16.67% (5/30) vs. 26.67% (8/30)] of the experimental group were lower than those of the control group (all P < 0.05), the mortality rate of the experimental group was slightly lower than that of the control group [26.67% (8/30) vs. 30.00% (9/30)] without statistical significance (P > 0.05). Plateau pressure (Pplat) and the peak airway pressure (PIP) at each time point were decreased after treatment in both groups, while the static lung compliance (Cst), the arterial partial pressure of oxygen (PaO2) and oxygenation index (PaO2/FiO2) were increased compared with those before treatment, especially the changes at 72 hours after recruitment in the experimental group were more significant than those in the control group [Pplat (cmH2O, 1 cmH2O = 0.098 kPa):15.6±4.0 vs. 21.2±5.6, PIP (cmH2O): 18.3±5.0 vs. 25.1±5.4, Cst (mL/cmH2O): 41.2±4.8 vs. 31.2±6.0, PaO2 (mmHg, 1 mmHg = 0.133 kPa): 90.93±6.45 vs. 80.27±4.51, PaO2/FiO2 (mmHg): 238.33±18.31 vs. 185.83±11.14]. Heart rate [HR (bpm): 110.23±7.92 vs. 98.23±8.44] and the central venous pressure [CVP (mmHg): 8.62±1.52 vs. 6.32±1.42] were significantly higher than those before treatment, the mean arterial pressure [MAP (mmHg): 86.74±7.65 vs. 94.92±10.93] and cardiac output [CO (L/min): 5.32±1.36 vs. 6.42±1.32] were significantly reduced compared with those before treatment (all P < 0.05). The values of HR, MAP, CVP, CO at 5 minutes after recruitment were (97.87±5.77) bpm, (94.54±6.87) mmHg, (6.33±1.44) mmHg, (6.32±1.41) L/min, respectively. The changes of these parameters were not significant when compared with those of the basal conditions (P > 0.05) Conclusions Based on the lung protective ventilation in the early stage, sequential RM is applied in treatment of patients with SAP complicated with ARDS, after the IAP is essentially returned to a normal, which is beneficial to improving lung compliance, promoting oxygenation, shortening the time of mechanical ventilation, reducing the length of ICU stay, and decreasing the incidence of VAP without any obvious hemodynamic influence.

Objective:To explore the prolonged therapeutic regimen for patients with plaque psoriasis, who showed a positive response to 4-week treatment with tazarotene/betamethasone dipropionate cream, but were not completely cured.Methods:A multicenter, randomized, open-labelled, parallel-controlled clinical study was conducted. A total of 232 patients with plaque psoriasis were collected, who showed a positive response to previous 4-week treatment with 0.05%/0.05% tazarotene/betamethasone dipropionate cream, but were not completely cured with the psoriasis area and severity index[PASI] improvement rate being 50%-90%. At week 5, they were randomly and equally divided into 2 groups: test group receiving treatment with 0.05%/0.05% tazarotene/betamethasone dipropionate cream once a day, and control group receiving a sequential regimen of 0.05% tazarotene gel on weekdays once a day followed by 0.05%/0.05% tazarotene/betamethasone dipropionate cream on weekends once a day. After 2-and 4-week prolonged treatment, the efficacy and safety of the 2 therapeutic regimens were evaluated and compared. Measurement data were compared between 2 groups by using covariance analysis or t test, and enumeration data were compared by using chi-square test. Results:From the 5th to the 8th week, 200 out of the 232 patients completed the treatment. Data collected from 110 patients in the test group and 112 in the control group were enrolled into the full analysis set, and those from both 113 patients in the test group and control group were enrolled into safety analysis set. After consecutive 6-and 8-week treatment, the decline rates of the PASI score were 73.05% ± 16.69% and 78.46% ± 15.40% respectively in the test group, which were significantly higher than those in the control group (66.73% ± 21.77%, 67.02% ± 34.19%, respectively, both P < 0.05) . After 6-week treatment, the proportion of subjects who achieved PASI90 was significantly higher in the test group (14 cases, 12.7%) than in the control group (5 cases, 4.5%, χ2=4.842, P=0.028) ; After 8-week treatment, the proportions of subjects who achieved PASI75 and PASI90 (61.8%, 23.6%, respectively) were significantly higher in the test group than in the control group (48.2%, 12.5%, respectively, both P < 0.05) . During the consecutive 8-week treatment, there was no significant difference in the incidence rate of adverse reactions between the test group (15.0%) and control group (23.9%, χ2=2.822, P=0.093) . Conclusion:For patients who showed a positive response to 4-week treatment with 0.05%/0.05% tazarotene/betamethasone dipropionate cream, but were not completely cured, the continuous use of 0.05%/0.05% tazarotene/betamethasone dipropionate cream for 4 weeks is a superior therapeutic regimen compared with the sequential regimen of 0.05% tazarotene gel followed by 0.05%/0.05% tazarotene/betamethasone dipropionate cream.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease caused by inflammatory cells. Various inflammatory cells involved in RA include fibroblast-like synoviocytes, macrophages, CD4+T-lymphocytes, B lymphocytes, osteoclasts and chondrocytes. The close interaction between various inflammatory cells leads to imbalance of immune response and disorder of the expression of mRNA in inflammatory cells. It helps to drive production of pro-inflammatory cytokines and stimulate specific antigen-specific T- and B-lymphocytes to produce autoantibodies which is an important pathogenic factor for RA. Competing endogenous RNA (ceRNA) can regulate the expression of mRNA by competitively binding to miRNA. The related ceRNA network is a new regulatory mechanism for RNA interaction. It has been found to be involved in the regulation of abnormal biological processes such as proliferation, apoptosis, invasion and release of inflammatory factors of RA inflammatory cells. Understanding the ceRNA network in 6 kinds of RA common inflammatory cells provides a new idea for further elucidating the pathogenesis of RA, and provides a theoretical basis for the discovery of new biomarkers and effective therapeutic targets.
