Objective To study the effect of immunotherapy on expression of CD14+mHLA-DR and the serum levels of immunoglobulin (IgG, IgA and IgM) in patients with severe pneumonia, so as to discuss the feasibility of immunotherapy for severe pneumonia. Methods From January 2012 to April 2014, 120 cases of patients with severe pneumonia treated in the intensive care unit (ICU) and pneumonia department were collected. Patients were randomly divided into control group (60 cases) and treatment group (60 cases). The control group was administrated with conventional therapy , and the treatment group was given thymosin α1 for immune treatment for 7 days. The mHLA-DR expression and the level of IgG , IgA and IgM of the two groups before and after the treatment were compared. Results After thymosin α1 treatment, mHLA-DR expression rate was elevated , and the serum levels of IgG , IgA and IgM were elevated in the treatment group , and the difference was statistically significant (P < 0.05). While there was no statistically significant difference betweenthe above indicators before and after treatment (P > 0.05). Conclusion After immune treatment with the use of thymosin α1 , immunologic suppression can be prevented , and cellar immune function of severe pneumonia patients can be improved.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.
METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.
RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).
CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

OBJECTIVETo investigate the therapeutic effect of Qingyi Decoction (QYD) and tetrandrine (Tet), used singly or combind, in treating miniature pigs with severe acute pancreatitis (SAP) and its mechanism.
METHODSThirty-two Guizhou miniature pigs were made into SAP model by pancreatic duct retrograde injection of 5% sodium taurocholate. They were randomly divided into 4 groups: the control group, the QYD group, the Tet group and the combined treated group. The serum amylase activity and interleukin-1 and 6 (IL-1, IL-6) contents in serum from vena cava and portal vein were tested by biochemistry and radioimmunoassay (RIA). Serum emodin and plasma Tet levels were measured by high performance liquid chromatography (HPLC) 24, 48 and 72 hrs after treatment. And the pathological changes of pancreas, lung and liver were observed under microscope.
RESULTSThe mortality of SAP pigs was reduced significantly and the inflammatory injury of the organs was ameliorated obviously in all treated groups, and the increased amylase activity and IL-1, IL-6 levels was attenuated. The therapeutic effect was much more obvious, and the plasma Tet level at different time points were much higher in the combined treated group than those in the other two groups treated by single drug (P < 0.01).
CONCLUSIONBoth QYD and Tet could treat effectively SAP through multiple pathways, combination of them reveals an elevation of serum drug concentration and shows a synergistic effect.

Objective:To investigate the infection status of Yersinia in the main host animals of plague in Xiahe and Luqu counties, the Himalayan marmot plague foci of Gansu Province, and to provide a basis for exploring the epidemic status of plague in these foci. Methods:Samples of the ileocecal region and contents, pharyngeal swabs (or tongue roots), and blood of the main host animals of plague in Xiahe County and Luqu County where the plague were active in the 1950s and 1960s were collected from 2014 to 2018. The Yersinia isolation, virulence determination and F1 antibody detection were performed, respectively. Results:Totally 24 strains of Yersinia were detected in 958 samples of ileocecal region and contents with a bacterial detection rate of 2.51%, which were 13 strains of Yersinia enterocolitia (Y.e), 1 strain of Yersinia kristensenii (Y.k), 2 strains of Yersinia frederiksenii/ intermedia (Y.f/i), 6 strains of Yersinia intermedia (Y.i), 1 strain of Yersinia aldouae (Y.a) and 1 strain of Yersinia massiliensis (Y.m). Totally 19 strains of Yersinia were detected in 958 samples of pharyngeal swabs (or tongue roots), and the detection rate was 1.98%, which were 8 strains of Y.e, 1 strain of Yersinia pseudotuberculosis (Y.p), 4 strains of Y.k, 1 strain of Y.f/i, 4 strains of Y.i, and 1 strain of Yersinia ruckeri (Y.r). The virulence types of 21 strains of Y.e were ail -ystA -ystB +yadA -virF -rfbc -, ail -ystA -ystB -yadA -virF -rfbc -, respectively, accounting for 9.52% (2/21) and 90.48% (19/21), none were pathogenic. The results of F1 antibody in 1 079 serum samples were all negative. Conclusions:Yersinia are widely found in the pharynx and intestines of the main host animals of plague in Xiahe and Luqu counties, and the Y.e detected are all non-pathogenic strains. The results of this investigation can provide clues for further study on the preservation of Yersinia pestis in host animals and their living environment.

This study was aimed to investigate the T cell (helper T cells) immune status in ITP patients and its relation with therapeutic response. 20 de novo ITP patients were enrolled (8 males, 12 females) with a median age of 41 (20 to 81). Real-time RT-PCR method was used to measure the gene expression of Th cells including T-bet, IFN-γ, GATA-3, TGF-β, Foxp3, IL-2, IL-4 in PBMNC of ITP patients before and after conventional dose of prednisone therapy [1 mg/(kg·d)] and in PBMNC of 20 normal controls. The results showed that T-bet, IFN-γ and IL-2 were significantly over-expressed in PBMNC of ITP patients before treatment compared with that in normal controls (p < 0.01), and compared with that before treatment, T-bet, IFN-γ, and IL-2 were markedly down-regulated in ITP patients after treatment. Before treatment, the expressions of Foxp3, TGF-β, GATA3 and IL-4 in ITP patients did not show difference from normal controls, while after treatment Foxp3 were more up-regulated than that before treatment (p < 0.05). After treatment, TGF-β expression showed a different pattern between old and young patients. TGF-β expression was down-regulated (p < 0.05) among ITP patients younger than 60, while up-regulated in older patients. It is concluded that there is an imbalance of Th1/Th2/Treg cytokines in ITP patients, which can be reversed by glucocorticoid treatment. The conventional dose of glucocorticoid may be regarded as effective therapy for de novo ITP patients, it may correlate with improvement of imbalance between Th1/The2/Treg cytokines.

OBJECTIVETo investigate the number of peripheral blood CD5(+) B cells and their ability of secreting IL-10 in patients with immune thrombocytopenia (ITP).
METHODSPeripheral blood lymphocytes were isolated from 57 pre-treated, 40 post-treated ITP patients and 25 controls using Ficoll-Hypaque density centrifugation and then stained with PE-CD5/FITC-CD19 for flow cytometric analysis. After 24-hour culture, lymphocytes were stained with APC-IL-10 for intracellular cytokine detection. ELISA assay was employed to determine IL-10 concentration in supernatants.
RESULTSThe percentage and absolute number of CD5(+) B cells in peripheral blood from pre-treated ITP patients were significantly higher than that from normal controls (3.75 ± 2.37)% vs (2.10 ± 1.08)%, P < 0.01; (6.29 ± 5.77)× 10(7)/L vs (3.06 ± 1.90)× 10(7)/L, P < 0.01. CD5(+) B cells expressed more intracellular IL-10 than other lymphocyte subsets both in ITP patients and normal controls. The percentages of IL-10(+) cells within CD5(+) B cells in pre-treated ITP patients and normal controls were (29.51 ± 20.73)% and(15.90 ± 9.58)%, respectively(P < 0.01). Intracellular mean fluorescence intensity (MFI) of IL-10 in CD5(+) B cells was 27.95 ± 13.99 in pre-treated patients, which was significantly higher than that in controls (P < 0.01). In contrast, IL-10 concentration in supernatants was (173.05 ± 102.50) ng/L in pre-treated ITP group, which was lower than that (230.61 ± 76.96) ng/L in controls. In patients who achieved remission, the number of CD5(+) B cells decreased to level comparable to normal controls. While intracellular IL-10 MFI of CD5(+) B cells in post-treated ITP patients remained as high as in pre-treated ones, the IL-10 concentration in supernatants increased to level similar to controls.
CONCLUSIONThe significantly increased number of CD5(+) B cells and accumulated IL-10 in CD5(+) B cells suggested impaired IL-10 secretion in ITP patients. The number and the ability of secreting IL-10 of CD5(+) B cells could be restored after effective treatments in patients with ITP.

OBJECTIVETo study the effect and the mechanism of Xuesaitong drop pills (total saponins in Radix Notoginseng; XDP) on experimental thrombosis, thrombolysis and blood theology.
METHODFirst, the rats were randomly divided into five groups: control, XDP (90, 30, 10 mg x kg(-1)), Xuesaitong tablet (XP) 30 mg x kg(-1). Then the effect of the drugs on thrombus and thrombosis was studied after the ratsthrombosis was induced by the arteriovenous shunt. Second, the rats were randomly divided into seven groups: model, XDP (90, 30, 10 mg x kg(-1)), XT (90, 30 mg x kg(-1)), lumbrukinase capsule. Then the effect of the drugs on thrombus and thrombosis was studied after the rats'thrombosis was induced by the electrical stimulation of common carotid artery. Third, the rats were randomly divided into six groups: control, model, XDP (80, 40 mg x kg(-1)), XT (40, 20 mg x kg(-1)). Then the effect of the drugs on blood circulation promoting was observed after the rats'acute blood stasis induced by adrenalin and icy water.
RESULTXDP 90, 30 mg x kg(-1) could notably lighten the wet-weight and dry-weight of thrombus in the arteriovenous shunt model in rats in a dose-dependent manner (P < 0.01). XDP 90 mg x kg(-1) with intragastric administration for 3 days had the satisfactory effect on thrombolysis after the rat's thrombosis was induced by the electrical stimulation of common carotid artery (P < 0.01). XDP 80, 40 , 20 mg x kg(-1) reduced significantly erythrocyte aggregation (P < 0.01) and decreased the whole blood viscosity at low shear rate (P < 0.05). XDP 80, 40 mg x kg(-1) reduced the whole blood viscosity at high shear rate and plasma viscosity (P < 0.05). XDP 80 mg x kg(-1) decreased the whole blood viscosity at high shear rate (P < 0.05).
CONCLUSIONXDP can significantly inhibit the thrombosis and has the satisfactory effect on thrombolysis. One kind of the mechanism is related to the effect on blood rheology.
