Objective:Serum soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is a useful biomarker of bacterial infection. However, the diagnostic value of sTREM-1 of alveolar fluid in pulmonary infection is still unclear. This article aimed to explore the value of sTREM-1 of alveolar fluid in the early diagnosis of ventilator-associated pneumonia (VAP) by systematic review of relevant literatures.Methods:CNKI, Wanfang, VIP, PubMed/Medline and Embase databases were retrieved. Articles on diagnosis of VAP by sTREM-1 before June 30, 2019 were collected. QUADAS-2 scale provided by Cochrane Collaboration Network was used to evaluate the quality of diagnostic experiments. RevMan 5.3 and Stata 13.0 software were used to complete Meta-analysis. The levels of sTREM-1 between VAP and non-VAP patients were analyzed by Meta-analysis, and then diagnostic test Meta-analysis was conducted. Heterogeneity, sensitivity and publication bias were analyzed.Results:A total of 24 articles were enrolled. QUADAS-2 scale indicated that the selected literature had low bias and high clinical adaptability. ① In Meta-analysis of sTREM-1 level in alveolar fluid, 20 articles were selected and found to have high heterogeneity ( I2 = 94.4%, P = 0.000). The random effects models were used for Meta-analysis. It was indicated that the sTREM-1 level in alveolar fluid of VAP group was significantly higher than that of non-VAP group with significant difference [standardized mean difference ( SMD) was 1.47, 95% confidence interval (95% CI) was 1.00-1.95, Z = 6.14, P = 0.000]. By subgroup analysis and Meta-regression analysis, no source of heterogeneity was found. Sensitivity analysis suggested that the results of this Meta-analysis were robust and credible, and Begg funnel plot analysis showed that there was no significant publication bias ( Z = 1.46, P = 0.143). ② A total of 18 articles were included in the Meta-analysis of diagnostic experiments. Deek funnel plot showed publication bias ( P = 0.012). The combined sensitivity was 0.87 (95% CI was 0.81-0.91), specificity was 0.80 (95% CI was 0.73-0.86), and diagnostic odds ratio ( DOR) was 26 (95% CI was 13-50). Subgroup analysis of three different sources of alveolar fluid (bronchoalveolar lavage fluid, endotracheal aspiration fluid and exhaled ventilator condensate) showed that STREM-1 had a certain value in early diagnosis of VAP. The I2 of combined DOR was 35.4%, and I2 of sensitivity was 79.46%, I2 of specificity was 77.61%, suggesting heterogeneity in the selected literature. Subgroup analysis found that nationality, subject design, sample source, sample size and diagnostic "gold criteria" were related to heterogeneity, but not age. The area under synthetic receiver operating characteristic (SROC) curve (AUC) was 0.90 (95% CI was 0.87-0.92). Conclusions:The detection of sTREM-1 level in alveolar fluid can be used for the early diagnosis of VAP with high sensitivity and specificity. If combined with other biomarkers, it may have more diagnostic value.

OBJECTIVETo investigate anticancer effect and potential mechanism of tanshinone II(A) (Tan II(A)) on human nasopharyngeal carcinoma cell line CNE cells.

METHODAntiproliferative effect of Tan II(A) on CNE cells was evaluated by morphological examination, cell growth curves, colonial assay and MTT assay. Apoptosis detection was carried out using Hoechest 33258 and PI double-dyeing method. Intracellular Ca2+ concentration and mitochondria membrane potential were detected by fluorospectrophotometer. Bad and MT-1A transcript analysis in CNE cells was analyzed by real-time reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTTan II(A) could inhibit CNE cells proliferation in dose- and time-dependent manner. 50% inhibiting concentration of Tan II(A) on CNE cells in 24, 48, 72 h was 45.7, 24.8, 3.3 mg x L(-2), respectively. Typical apoptotic morphology such as chromatin aggregation was observed in CNE cells with Tan II(A) treated for 24 h, and the apoptotic inducing effect was in a dose-dependent manner. After treated with Tan II(A), intracellular Ca2+ concentration of CNE cells was increased, mitochondria membrane potential of the cells was decreased, relative mRNA level of Bad and MT-1A was up-regulated.

CONCLUSIONTan II(A) had anticancer effect on CNE cells through apoptosis via calcineurin-dependent pathway and MT-1A downregulation.

Aim To investigate the effect of Isorhynchophylline(Isorhy)on platelet aggregation or thrombosis,and explore the mechanism of it's action.Methods Rat platelet aggregation was determined.cAMP contents were assessed by Born's method and radioimmunoassay respectively.The effect of Isorhy on rat's thrombosis was observed with the thrombogenesis model of artery-vein bypass.Results Isorhy(0.65 mmol?L-1,1.30 mmol?L-1)was shown to markedly inhibit the rat's platelet aggregation induced by ADP or thrombin in a concentration-dependent manner(P

Aim To study the protective effects of Rhynchophyll a of total alkaloids ( RTA ) on cerebral ischemia/reperfusion injury and the possi ble mechanism of action. Methods The effects of RTA on decapit ated gasping model and model of middle cerebral artery ischemia 2 h/reperfusion 22 h were observed. The neurological scores, cerebral infarct volume and cerebr al water content after ischemia/reperfusion were observed in rats respectively. The activities of NOS and SOD and the content of MDA in rat's brain tissue were measured. Neuron apoptosis in ischemia penumbral area were detected by terminal depoxynucleotidyl transferase mediated dUTP-biotin nick end labeling ( TUNEL ) . Results The average gasping times in mice treated with RTA 50 , 75 mg?kg -1 was significantly prolonged. The cerebral infarct volume and cerebral water content in rats treated with RTA 40, 60 mg?kg -1 were sign ificantly decreased in ischemic rats. RTA 40, 60 mg?kg -1 increased the ac tivity of SOD ,and decreased the activity of NOS and the content of MDA in the i schemic brains of rats. The number of apoptotic neurons in ischemia penumbral ar ea of cerebral tissue of rats treated with RTA 40, 60 mg?kg -1 was signif icantly lower than that in control rats. Conclusions RTA has pr otective effect on cerebral ischemia/reperfusion injury; this may be related to inhibit the activity of NOS and lipoperoxidation, and increasing the activity of SOD and decreasing neuron apoptosis.

Objective To study the effect of protopine (Pro) on the intracellular free calcium ions of the smooth muscular cells of the thoracic aorta in rats. Methods The procedure of calcium absence-calcium addition was designed to observe the changes of the level of calcium ions in the strips of the smooth muscle of the thoracic aorta indirectly. The concentration of calcium ions in the smooth muscle of the thoracic aorta was determined with Fura-2/AM loaded SMCs. The elevation of calcium ions was induced with norepinephrine (NE). The concentration of potassium ions was observed in the presence of Pro. Results Pro significantly inhibited the NE-induced transient contract of the smooth muscle of the thoracic aorta in calcium-free medium and long-lasting contraction after the addition of calcium ions in a concentration-dependent manner. In Fura-2/AM loaded SMCs, Pro (50 ?mol/L or 100 ?mol/L) exerted no effect on the resting calcium ions but obvious effect on the NE-induced and high potassium level-induced elevation of calcium ions. In the presence of extracellular calcium ions, Pro (50 ?mol/L) decreased the NE-induced elevation of calcium ions but showed no effect on potassium-induced elevation of calcium. Pro (100 ?mol/L) significantly decreased NE-induced and high potassium level-induced elevation of calcium ions. Conclusion Pro reduces NE-induced or high potassium level-induced elevation of calcium ions in the smooth muscle of the thoracic aorta through its effect on calcium release and/or calcium influx.
