Objective To observe clinical effects of Sanqi wound tablets combing with Western medicine to conservative treatment of acute thalamic hemorrhage.Methods72 patients with acute thalamic hemorrhage from Department of Neurosurgery from December 2014-June 2016 were grouped two groups by random number table method.The control group was treated with Western medicine, and observation group was treated with Sanqi wound tablets combing with Western medicine.Relevant indicators were analyzed between two groups.ResultsEffective rate of observation group was 88.89%, higher than control group with 69.44%(P<0.05).NSE and hs-CRP level of observation group were (7.02±1.86)μg/L,(11.75±2.64)mg/L, lower than control group(13.98±2.01)g/L,(19.82±3.07)mg/L(all P<0.05).Fugl-Meyer and NIHSS of observation group were (93.07±4.25),(12.01±2.30)points, better than control group(81.16±4.10),(18.42±2.45)points(all P<0.05).Thalamic residual bleeding of observation group was (2.82±0.41)mL, lower than control group (3.97±0.57)mL(P<0.05).ConclusionOn the basis of Western medicine, Sanqi wound tablets can improve the therapeutic effect, reduce inflammation, improve the patient's motor function and nerve defect degree and accelerate the absorption of hematoma.

Objective To clinically validate the precision of diagnostic Sepsis-3 criteria, and to guide and generalize its clinical application.Methods A multicenter retrospective observational study was conducted. The patients admitted to intensive care unit (ICU) of 6 tertiary hospitals in Zhejiang Province from January to June 2015 were enrolled, and the patients satisfying the diagnostic criteria of Sepsis-2 and Sepsis-3 were screened. Population characteristics between the patients satisfying two editions were compared, and the diagnosis accuracy rate in different degree hospitals were investigated. According to the doctor's diagnosis, the patients who met the criteria of Sepsis-2 were divided into diagnosis group and non-diagnosis group, and the factors influencing the diagnosis of sepsis were analyzed by logistic regression. The patients meeting Sepsis-2 but no meeting Sepsis-3 were served as exclusion group, and those meeting Sepsis-2 and Sepsis-3 were served as enroll group, and the characteristics of patients between the two groups were compared. Receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of systemic inflammatory response syndrome (SIRS) score, sepsis-related quick sequential organ failure assessment (qSOFA) and sequential organ failure assessment (SOFA) on death, and whether the consistency of qSOFA and SOFA would affect the sensitivity of definition. The patients meeting Sepsis-2 were divided into non-survived group and survived group, and the factors associated with death were analyzed by logistic regression.Results Finally, 1423 patients were enrolled, 3 patients with age < 18 years and 19 patients with missing data were excluded. There were 363 patients and 329 patients met Sepsis-2 and Sepsis-3, respectively. No significant differences were found in populationcharacteristics between the groups of Sepsis-2 and Sepsis-3 (allP > 0.05) except for acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score [19.10 (8.00) vs. 20.28 (8.00),P < 0.05]. It was shown on the clinical data analysis of the hospitals that the patients meeting Sepsis-2 and Sepsis-3 in hospital 3 had the highest 28-day mortality (60.4% and 60.0%) with the lowest rate of diagnosis (0). While in the hospital 1, the patients had the lowest 28-day mortality (22.9% and 27.2%), and the rate of diagnosis was 19.5%. Interestingly, the patients in hospital 4 had the highest diagnosis rate of sepsis (44.8%), but 28-day mortality was both 58.6%. It was shown by logistic regression analysis that the patients with old age [odds ratio (OR) = 0.970,P = 0.021], high blood lactate (OR= 0.443,P = 0.004), high blood pressure (OR = 0.957,P = 0.009) and low oxygenation index (OR = 1.004,P = 0.024) were easy to neglect diagnosis. Compared with Sepsis-3 exclude group, the patients in Sepsis-3 enroll group were older [years: 68.52 (26.00) vs. 53.75 (18.00),P < 0.01] with higher APACHEⅡ score [20.38 (8.00) vs. 7.72 (6.00),P < 0.01], higher blood lactate [mmol/L: 3.45 (3.00) vs. 1.95 (1.20), P > 0.05], longer length of ICU stay [days: 22.42 (22.00) vs. 15.13 (16.00),P < 0.01], and higher 28-day mortality [45.29% (149/329) vs. 14.71% (5/34),P < 0.01], indicating that the diagnostic efficiency of Sepsis-2 was low, the diagnostic specificity of Sepsis-3 was high, and the prognosis of Sepsis-3 patients was worse. It was shown by ROC curve analysis that the prognostic value of SIRS, qSOFA and SOFA to mortality was gradually increased [area under ROC curve (AUC) was 0.567, 0.597, 0.683, respectively], but the prognostic value were all low. Comparing patients meeting qSOFA and (or) SOFA in Sepsis-2, significant differences were found in APACHE Ⅱ score [17.55 (7.00) vs. 23.24 (8.00)] and 28-day mortality [38.75% (31/80) vs. 58.59% (75/128), bothP < 0.01]. The patients who just met the qSOFA or SOFA, their 28-day mortality was up to 38.75%, suggesting that qSOFA should not be ignored. Compared with survived group, the patients in survived group were older with higher APACHE Ⅱ score and shorter length of ICU stay (allP < 0.05). It was shown by logistic regression analysis that APACHE Ⅱ score (OR = 1.199,P = 0.000) and length of ICU stay (OR = 0.949,P = 0.000) were related with death.Conclusion Patients satisfied Sepsis-3 were easier to develop more organ failure, Sepsis-3 and higher death prediction than Sepsis-2 and higher diagnosis specificity, but data shows that there is extra room for improvement.

Objective To investigate the effect of lidocaine on Staphylococcus aureus exotoxin-stimulated peripheral blood mononuclear cells (PBMCs) from patients with atopic dermatitis (AD).Methods Peripheral blood samples were collected from 6 patients with AD,and PBMCs were isolated by a routine method.Then,the PBMCs were stimulated by the Staphylococcus aureus exotoxin toxic shock syndrome toxin-1 (TSST-1) in the absence or presence of lidocaine at varying concentrations.The 3H-TdR incorporation method was performed to detect the proliferation of monocytes,and enzyme-linked immunosorbent assay (ELISA) to quantify the levels of T helper type 1 (Th1) and Th2 cytokines released by PBMCs.Human HaCaT keratinocytes were co-cultured with lidocaine-and TSST-1-stimulated PBMCs from patients with AD for 72 hours,then,Western blot was conducted to examine the expression of filaggrin protein in HaCaT cells.Results TSST-1 (100 μg/L) significantly enhanced the proliferation of PBMCs from patients with AD (stimulation index =75 ± 2.12,P ＜ 0.05),as well as the release of tumor necrosis factor-α (TNF-α),interferon (IFN)-γ,interleukin (IL)-2,IL-12,IL-4,IL-5 and IL-13 by the PBMCs (all P ＜ 0.05).Compared with the blank control group,100 μmol/L lidocaine significantly inhibited the TSST-1-stimulated proliferation of PBMCs from patients with AD (stimulation index =58 ± 3.14,P＜ 0.05),as well as the release of IL-4,IL-5,IL-13,TNF-α and IFN-γ by the stimulated PBMCs (all P ＜ 0.05).Western blot showed that 100 μmol/L lidocaine significantly blocked the down-regulation of filaggrin expression in HaCaT cells (P ＜ 0.01).Conclusion Lidocaine has a significant inhibitory effect on the activation of TSST-1-stimulated PBMCs from patients with AD.

Background and purpose:Hepatocellular carcinoma suppressor gene-1(HCCS1)is a potential hepatocellular carcinoma supressor gene,and it also plays an important role in sorting of some cytoplasmic proteins.Its carcinoma suppressor function may be related to its sorting function.So it is important to identify the minimum region of functional sequence in HCCS1 that related to the transportation.Methods:The expression vectors containing various lengths of HCCS1 gene were constructed and transfected into HeLa cells mediated by liposomes.The localizations of different HCCS1 fragments and the colocalizations of M6PR with various truncated HCCS1 were determined by laser scanning confocal microscopy,respectively.Results:10 different expression vectors containing various lengths of HCCS1 gene were successfully constructed,it had been shown that the polar localization of HCCS1 protein and the co-localizations with M6PR disappeared when HCCS1 gene was truncated to 1 120 bp from the 3'end by laser scanning confocal microscopy.Conclusions:We identified the minimum localization of the HCCS1 functional sequence that related to the transportation.

OBJECTIVETo investigate the role of histone acetylation in regulating influenza virus replicative intermediate double-stranded RNA (dsRNA)-induced interleukin-6 (IL-6) expression in A549 cells.

METHODSA549 cells were treated with influenza virus replicative intermediate dsRNA, histone deacetylase (HDAC) inhibitor trichostatin A (TSA), or HADC small interfering RNA (siRNA). The changes in the cellular IL-6 promoter activities were detected by dual-luciferase assay, and IL-6 mRNA and protein expressions in the cells were determined using real-time RT-PCR and ELISA, respectively.

RESULTSInfluenza virus replicative intermediate dsRNA obviously up-regulated IL-6 expression in the cells. HDAC inhibitor TSA significantly enhanced the activity of IL-6 promoter and increased IL-6 mRNA expression in A549 cells, and HDAC3 may play an important role in this process. HDAC inhibitor TSA and DNMT inhibitor DAC showed no synergic effect in regulating IL-6 expression.

CONCLUSIONSInfluenza virus replicative intermediate dsRNA-induced IL-6 expression in A549 cells is regulated by histone acetylation.
