Objective To envaluate the accuracy of Photoplethysmograph pulse wave in monitoring stress reaction to harmful stimulation. Methods Patients (n=75) were randomly assigned to three groups according to the dosages of fentanyl that were administrated ( 4, 5 and 6 g/kg were given to F4, F5, F6 group respectively (n=25) in each group. Heart rate (HR), Systemic blood pressure (SBP), Diastolic blood pressure (DBP), SpO2, the skin temperature of finger, perfusion index (PI), epi?nephrine(E) and Norepinephrine (NE) were recorded at following time points:just in operation room (T1), 2 min after induc?tion (T2), at intubation (T3),1 min (T4) and 5 min (T5) after intubation. And the PPGPW was printed and measured at the same time points. Results PPGA and PI were significantly increased while E and NE were significantly decreased in T2 and T5, compared with those baseline at T1 (P < 0.05). At T3, PPGA and PI were significantly decreased while NE markedly in?creased in group F4 and F5 compared to T1. At T3, E in group F4 were remarkably increased h while E in group F5 were of no obvious changed, compared with those at T1(P<0.05). PPGA and PI increased while E and NE decreased in group F6 at T2, T3 ,T4 and T5 compared with those at T1 (P<0.05). In summary, PI was negatively correlated with plasma E and NE while PP?GA was negatively correlated with plasma E and NE .Conclusion PPGA and PI are negatively associated with intensity of stress response. And they can reflect the stress reaction during the induction period of intravenous anesthesia accurately.

Food-born trematodes which parasitize liver, lung and intestine cause various trematodes diseases. There are a few common trematodes such as Clonorchis sinensis, Fasciola, Opisthorchis, Paragonimus, and Echinostoma. This review provides recent progress in techniques and methods for their immunodiagnosis. These methods are mainly used to diagnose with excretory-secretary antigen, recombinant antigen and antibodies of hosts, by means of enzyme-linked immunosorbent assay, immunoblotting, immunefluorescence, immunehistochemistry, proteomics and a lateral flow detection system so on. It is beneficial to improve diagnostic and accuracy rates when all this methods are used synthetically.

Objective To investigate the role of Th9 cells in primary biliary cirrhosis and its clinical significance.Methods The percentages of Th9 cells in patients with PBC (n=38)and healthy controls (n=38)were measured by flow cytometry. Patients clinical data were collected and Mayo risk scores were calculated.Determined the levels of IL-9,PU-1 and TGF-βmRNA expressions and the protein levels of IL-9 in plasma.Further analyzed the correlation between Th9 cells and clinical parameters.Results Compared to healthy controls,Th9 cells percentage was higher in PBC patients and increased with dis-ease stages (t=27.29;P<0.01).IL-9,PU-1 and TGF-βmRNA expressions were increased compared with healthy controls (t=14.69,23.92,10.48;all P<0.01)and the protein level of IL-9 was also up-regulated (t=11.66;P<0.01).The clinical parameters (ALP,AST,ALT,GGT and TBIL)were higher than healthy controls (t=10.94,12.95,10.56,14.92,27.70;all P<0.01).Moreover,the percentage of Th9 cells were positively correlated to Mayo risk,ALT,AST,GGT and TBIL (P<0.05).Conclusion Th9 cells may be involved in the pathogenesis of PBC and related to the disease stage,which provides new clues for future immunotherapy.

Objective To explore the change of microRNA let-7b in heat acclimatization/heat stroke rat models and its relation with HSP70,IL-6,TNF-α,TGF-3 and IL-12,and analyze its clinical significance.Methods 60 male rats with almost the same anal temperature,weight,and weeks' age were selected from Laboratory Animal Center in the Second Military Medical University.They were randomly divided into control,heat acclimatization,heat stroke groups averagely.Heat acclimatization/heat stroke rat models were built in hot climate simulated animal tank,blood was collected from cordis apex and serum was separated.Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to test microRNA let-7b in serum,enzyme-linked immunosorbent reaction (ELISA) was to measure the protein level of HSP70,IL-6,TNF-α,TGF-β and IL-12 in serum.Kruskal-Wallis H test was used to analyze quantitative data in the three groups,Spearman rank correlation coefficient was used to reveal relation between two variables in heat stroke group.Results M values of miRNA let-7b in control,heat acclimatization,heat stroke groups were 0.99,1.04 and 1.93 separately,Q values were 0.30,0.25 and 0.44 (x2 =38.95,P＜0.001),separately,with statistical significance.The results of pairwise comparison showed no statistical difference in control and heat acclimatization (P＞0.05),but there were differences in control and heat stroke,heat acclimatization and heat stroke groups statistically (P＜0.05).Spearman correlation analysis showed that in heat stroke group,let-7b was positively related with HSP70,TNF-α and IL-6 (rs =0.579,0.498 and 0.609,P＜0.05) with statistical significance.Conclusion miR let-7b might involve in the pathology of heat stroke,it provided a potential biomarker for monitoring patients in high temperature and humidity clinically.

Objective To test the expression level of CD69+CD4+CD25-T cells in peripheral blood from patients with autoimmune pancreatitis,and further analyze its clinical significance.Methods Peripheral blood samples from 32 patients with AIP diagnosed in hematological department,Changhai Hospital and 32 health individuals examined at the same time were collected from September 2014 to December 2016,they were classified as experimental and control groups,separately.Peripheral blood mononuclear cells (PBMCs) was acquired by density gradient centrifugation,CD69+ CD4 + CD25-T cells in PBMCs were tested by flow cytometry,and the expression level of cytokines in plasm was by ELISA.The comparison of varies between the two groups was measured by two independent samples' t test.The relationship between the two measurement data was measured by pearson correlation coefficient.Results The expression levels of CD69 + CD4 + CD25-T in experimental and control groups were 10.36％±3.68％ vs 3.99％±1.45％ (t=9.110,P＜0.0001).The expression level of TGF-β was 399.86±121.88 vs 143.87±56.22 pg/ml (t=10.79,P＜0.000 1),both with statistical significance.The levels of CD69+CD4+CD25-T in experimental was positively correlated with TGF-β (r=0.653,P＜0.001) and negatively with IL-4,IFN-γ,IL-2 (r=-0.442,-0.567,-0.351,P＜0.05) and there was statistical significance.Conclusion CD69+CD4 +CD25-T cells might involve the immunopathology of AIP and could be the potential biomarker for clinical diagnosis and therapy.
