Objective To explore the value of serum microRNA-155-5p and -133a-3p (miR-155-5p and miR-133a-3p) expression for the diagnosis and prognosis evaluation of sepsis. Methods A prospective observational study was conducted. 105 sepsis patients admitted to emergency intensive care unit (EICU) of the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2016 were enrolled. They were divided into three groups according to the severity: 35 patients with sepsis, 35 with severe sepsis, and 35 with septic shock. At the same time, 35 healthy persons were selected as the control group. According to the prognosis, the patients were divided into improved group (n = 70) and in-hospital death group (n = 35). The clinical data of all the subjects were collected. The mRNA expressions of miR-155-5p and miR-133a-3p were determined by reverse transcription-polymerase chain reaction (RT-PCR). The receiver-operating characteristic curve (ROC) was plotted to evaluate their clinical value for the diagnosis and prognosis of sepsis. The binary logistic regression was used to analyze the risk factors affecting the prognosis of sepsis patients. Results ① The mRNA expressions of serum miR-155-5p and miR-133a-3p were gradually increased with the aggravation of sepsis. The mRNA expression of miR-155-5p (2-ΔCt) in sepsis, severe sepsis, sepsis shock groups was 1.89±0.48, 2.21±0.41, 2.79±0.73 (F = 23.737, P = 0.000), and the mRNA expression of miR-133a-3p (2-ΔCt) was 1.38±0.31, 1.74±0.65, 2.08±0.47, respectively (F = 27.710, P = 0.000). It was shown by ROC curve analysis that the area under the ROC curve (AUC) of serum miR-155-5p and miR-133a-3p for the diagnosis of sepsis was 0.855 [95% confidence interval (95%CI) = 0.761-0.949] and 0.769 (95%CI = 0.666-0.872) respectively. The cut-off value of miR-155-5p for the diagnosis of sepsis was 1.64, the sensitivity was 85.3%, and specificity was 80.6%. While the cut-off value of miR-133a-3p was 0.82, the sensitivity and specificity were 97.9% and 54.8% respectively. ② Compared with improved group, the patients of in-hospital death group were more serious, and procalcitonin (PCT), C-reactive protein (CRP), D-dimer, lactic acid (Lac), sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, and the mRNA expressions of miR-155-5p and miR-133a-3p were significantly increased (all P < 0.05). While there was no statistically significant difference in gender, age, white blood cells (WBC), serum creatinine (SCr) between the two groups (all P > 0.05). It was shown by binary logistic regression analysis that Lac [odds ratio (OR) = 0.514, 95%CI = 0.260-0.893, P = 0.024], sepsis severity (OR = 0.039, 95%CI = 0.023-2.955, P = 0.016), SOFA score (OR = 0.668, 95%CI = 0.474-0.825, P = 0.001), serum miR-155-5p expression (OR = 0.117, 95%CI = 0.020-0.530, P = 0.007) were the risk factors affecting the prognosis of patients with sepsis. Conclusions The expression of serum miR-155-5p and miR-133a-3p may be used as specific indicators for the diagnosis of sepsis. And the expression of miR-155-5p can be used as independent impact factor for the estimation of sepsis prognosis.

Objective To investigate the value of soluble epithelial cadherin(sE-cad)in the differential diagnosis of pleural effusion. Methods Patients were divided into malignant pleural effusion group,infective pleural effusion group and transudation group.sE-cad in pleural fluids obtained during the first thoracocentesis was measured by enzyme-linked immunosorbent assay(ELISA).The concentration of sE-cad in all kinds of pleural effusions was compared.The cut-off value of sE-cad for the differential diagnosis of benign and malignant pleural effusion was determined by ROC curve.The diagnostic value of sE-cad was also compared with common tumor markers such as CEA,CA199,CA125 and NSE.Results The concentration of sE-cad was significant higher in the malignant pleural effusion than in the benign pleural effusion[(38.38?4.15)ng/mL vs(14.17?0.80)ng/mL,P

Objective One typical case with stress cardiomyopathy was reported and the current knowledge of the syndrome was reviewed to improve relevant knowledge.Methods A 71-year-old female patient presented dyspnea and chest pain due to emotional stress.ECG,echocardiography,selective coronary artery angiography,left ventriculography,~(99)Tc~m-MIBI single photon emission computed tomography (SPECT),~(18)F-FDG SPECT and MRI were performed.Results Electrocardiogram at admission showed ST segment elevation and T wave inversion in leads V1—V4.Pathological Q wave occurred 1 week later,it disappeared 1 month later however and severe T wave inversion occurred.Normal or slightly elevated cardiac enzymes in the blood were found during the course.Left ventriculogram at admission showed left ventricular apical ballooning with LVEF of 30%.The ballooning volume was about 3/4 of left ventricular volume, without any corresponding coronary artery diseases found in coronary angiogram.The abnormal apical ballooning decreased significantly in the follow-up left ventriculogram performed one month later.The LVEF rose up to 63.6%.~(99)Tc~m-MIBI and ~(18)F-FDG SPECT showed mismatch of perfusion and metabolism in the corresponding region,indicating presence of viable myocardium.MRI showed left ventricular apical ballooning without perfusion defect and late enhancement,indicating viability of corresponding myocardium. Conclusions Emotional stress can cause transient left ventricular apical ballooning called"stress cardiomyopathy".Either ~(99)Tc~m-MIBI SPECT associated with ~(18)F-FDG SPECT or delayed enhancement MRI plays an important role in identification of myocardial viability,which can efficiently guide clinical treatment.

OBJECTIVE:To investigate the condition and characteristics of drug-induced liver injury (DILI) of anti-infective agents and provide reference for the prevention and treatment of anti-infective agents related DILI. METHODS:Based on retrospective analysis,a total of 572 DILI reports of anti-infective agents were collected from PLA ADR monitoring center during 2009 to 2013, and then analyzed statistically in terms of patient’s age and gender,main diagonosis,categories of DILI-inducing drugs,type,route of administration,occurrence time,lab indicator,DILI types and clinical manifestations,the application of liver protective drugs,out-comes,etc. RESULTS:Among 572 DILI cases,there were 412 cases(72.03%)of male patients and 160 cases(27.97%)of female patients,and average age of the patients was(44.54±23.75)years old. ADRs were related to 57 kinds of anti-infective agents in 6 cat-egories. Rifampin was the most frequent in suspected drugs,followed by isoniazid,moxifloxacin,fluconazole,azithromycin,cefurox-ime, cefoperazone/sulbactam, levofloxacin, cefoxitin and voriconazole. Intravenous infusion was the main administration route (74.48%). The occurrence time of ADRs was mainly within two weeks (86.19%). Hepatocellular damage (93.33%) was the main type in 360 cases of ADR for evaluation of liver injury types. The majority of cases(82.17%)were cured or improved after drug with-drawal and symptomatic treatment. CONCLUSIONS:Cephalosporin,fluoroquinolones,antituberculosis and antifungal drugs might be the common agents which caused liver injury. Hepatocellular damage is the most frequent type. Most of patients have a favourable prognosis. Clinical medical staffs should strengthen the awareness of DILI caused by anti-infective agents and ehance the prevetion of it.

Objective To investigate the effect of decompression with long-segment (L) or short-segment (S) fusion on the outcomes of the surgical treatment for degenerative adult scoliosis (ADS) patiens.Methods A retrospective study on 32 patients treated in our department for ADS from April 2013 to May 2015 was carried out, including 12 male and 20 female (1 : 1.7).Their average age was 66.4 (range: 51-77 years).All patients underwent decompression and fusion surgeries through posterior approach.They were divided into long-segment fusion group (L) and short-segment fusion group (S) according to fusion range.During follow-ups (FU), clinical outcomes were assessed by means of visual analog scale (VAS) and Oswestry disability index (ODI).Radiographic evaluation on full-length standing film included coronal Cobb's angle, distant between C7plumb line and center sacral vertical line (C7PL-CSVL), thoracic kyphosis (TK) angle, lumbar lordosis (LL) angle, pelvic incidence (PI), and pelvic tilt (PT), PI-LL, sagittal vertical axis(SVA).Postoperative complications were also recorded.Results All patients were followed up for average 2.2 years (range:1.5-3.5 years).No significant difference of age or gender was found between two groups (L: 22, S:10) of patients (P=0.066, 0.182).As for the fusion segments, group L (6.3±1.5) was more than group S (2.9±0.3) (P=0.001).Operation time and blood loss of group L were statistically more than group S (P＜0.05).Postoperative VAS sores of back pain and leg pain as well as ODI were all improved significantly in two groups (P＜0.05).At the final FU, back pain VAS was more in group L than in group S (P＜0.05) , but no significant difference was found in leg pain VAS between two groups (P＞0.05);at the final FU, group L's ODI showed better functional recovery than group S's[(12.8±9.3)％ vs.(25.4±11.4)％, P＜0.05].With no obvious difference in the two groups (P＞0.05), coronal Cobb's angle corrected more satisfactional in group L than group S (P＜0.05).The same situation was found in C7-CSVL correction in two goup in FU (P＜0.05).Sagital balance was restored to normal alignment better in group L than group S, with increase of lumbar lordosis after surgery.The overall incidence of postoperative complications was 31.3％, including wound infection, cerebrospinal fluid leakage, transient neurological symptoms and internal fixed rod breakage, more common in group L than group S.Conclusions Decompression and fusion with internal fixation showed good clinical outcomes in the treatment of ADS.Long-segment fusion yielded better coronal and sagittal correction outcomes with higher peri-operation risks;however, short-segment fusion showed higher safety with relatively inferior correction effect.Appropriate fusion mode should be chose according to the patient's deformity features.

Objective To investigate the effect of euphorbiasteroid on inducing the apoptosis of HL-60 cells and demonstrate whether the Fas/FasL signaling pathway is involved in the induction of apoptosis. Methods HL-60 cells were treated with dose of 2.5,10,40 μg/ml of euphorbiasteroid in vitro for 24 h respectively.After that,cell counting Kit-8 was used to detect cell proliferation.The morphology of HL-60 cells were observed under light and fluorescent microscopy.The early cell apoptosis was detected by using flow cytometry with Annexin Ⅴ-FITC /PI double staining.The expressions of Fas,FasL,caspase-8 and caspase-3 mRNA were analyzed by the method of RT-PCR.The activities of caspase-8 and caspase-3 were examined by chromatometry.Results Compared with 1640 control group,HL-60 cell proliferation was inhibited significant-ly by euphorbiasteroid.The inhibition rates were (34.9 ±3.7)%,(54.6 ±5.2)% and (61.3 ±4.3)%respectively.Moreover,HL-60 cells exhibited typical morphological features.Early cell apoptosis rates of HL-60 cells were (23.4 ±3.1)%,(35.7 ±4.3)% and (53.2 ±3.9)% respectively.Furthermore,the expressions of Fas,FasL,caspase-3 and caspase-8 mRNA were up-regulated significantly after euphorbiasteroid administration in a dose-dependent manner (P<0.01 ).After treated with euphorbiasteroid,the activities of caspase-8 and caspase-3 were significantly enhanced (P<0.01 ).Conclusion The up-regulation effect of euphorbiasteroid on Fas/FasL signaling pathway might contribute to the apoptosis of HL-60 cells.

Objective To observe the effects of Weipixiao on the ultrastructure of gastric mucosa capillaries in rats with precancerous lesions of gastric cancer ( PLGC). Methods The rats were randomized into six groups, including normal group, model group, Vatacoenayme Tablets group ( 0.2 g·kg-1·d-1) , and high-, middle-, and low- dose Weipixiao groups ( 15, 7.5, and 3.75 g·kg-1·d-1 respectively) . The rats received spontaneous intake of N-methyl-N’-nitro-nitrosoguanidine ( MNNG, 200 μg/mL) solution combined with irregular diet and intragastric administration of purgative herbs Xiao Chengqi Decoction ( 2 mL, containing 1 g/mL crude drug) for 18 weeks to induce spleen-deficiency PLGC. The pathological changes in gastric mucosa and the ultrastructure of gastric mucosa capillaries were observed under the transmission electron microscope. Results The model has been established successfully. Transmission electron microscopy results in the model group showed as severely swollen endothelial cells of gastric mucosa capillaries, severely-narrowing or even blocked vascular lumens, rough and discontinuous basement membrane, and swollen, degenerated or even absent pericytes. And the ultrastructure of gastric mucosa capillaries in high-, middle-, and low- dose Weipixiao groups were improved to some degrees, the effect of low-dose Weipixiao group being the best. Conclusion The improvement of the mucosal microcirculation of spleen-deficiency PLGC rats may be one of the pathohistological mechanisms of Weipixiao for spleen-deficiency PLGC.
