Traumatic coagulopathy is a serious complication of tissue damage caused by trauma.In clinic,it easily develops into multiple system organ failure and results in high mortality.Traumatic coagulopathy is a plurality of blood coagulation disorder,its pathogenesis is extremely complex and involves tissue damage,blood coagulation,anticoagulation and fibrinolysis,inflammation and many other pathophysiological aspects.An in-depth study on the pathogenesis of traumatic coagulopathy is very important to improve clinical effect.This paper tries to do a review of recent study progress from pathophysiological mechanisms and hopes to provide reference for clinical work.

Indoleamine 2,3-dioxygenase 1 (IDO1) is the rate-limiting enzyme in the degradation of tryptophan to kynurenine. IDO1 is highly expressed in some tumor tissues. IDO1 can deplete tryptophan in tumor microenvironment, inhibit T cell function, and mediate the immune escape of tumor cells. Thus, IDO1 is considered a potential target of tumor immunotherapy. Currently, there are several IDO1 inhibitors in clinical research studies. The mechanism of IDO1-mediated tumor immune escape and the structure of IDO1 inhibitors are summarized in this review.

OBJECTIVETo study the effect of medicines for activating blood and reinforcing Qi on the number of new micro-vessels and the protein expressions of VEGF and bFGF in the infarcted myocardium edge area of acute myocardial infarction (AMI) model in rats.

METHODThe AMI model of rats was established. After the successful model establishment, rats were randomly divided into the sham-operated group, the model group, the Danshen-Huangqi (1 : 2) group, the Danshen-Huangqi (1 : 1) group, the Chuanxiong-Huangqi (1 : 2) group, the Danshen group, the Chuanxiong group, the Chishao group and the Shexiang Baoxin pill group, with five rats in each group. Rats in each medicated group were orally administered with drugs as per 13.5 g x kg(-1) x d(-1) once everyday for three weeks. The immunohistochemical SP method was adopted to detect the expression of vWF in myocardial tissues, and count the number of micro-vessels (MVC). The protein expression of VEGF and bFGF in myocardial tissues were determined by Western blot.

RESULTThe new micro-vessels stained by vWF factor could be found in the infarcted myocardium edge area of the sham-operated group, the model group and all of medicated groups. The sham-operated group show unobvious new micro-vessels in myocardial tissues. A small amount of new micro-vessels could be seen in the infarcted myocardium edge area of the model group. Whereas a larger number of micro-vessels could be seen in the infarcted myocardium edge area of all of medicated groups. The differences between the sham-operated group and the model group had statistical significance (P < 0.05). The differences between each medicated group and the model group had statistical significance as well (P < 0.05 or P < 0.01). The lowest protein expression of VEGF and bFGF was found in myocardium of the sham-operated group, with the statistical significance compared with the model group (P < 0.05). Compared with the model group, each medicated group showed significant increase in the protein expression of VEGF and bFGF, with the statistical significance between them (P < 0.05 or P < 0.01).

CONCLUSIONThe Danshen group, the Chuanxiong group, the Chishao group, the Danshen-Huangqi (1 : 2) group, the Danshen-Huangqi (1 : 1) group and the Chuanxiong-Huangqi (1 : 2) group show the effect in promoting angiogenesis. Their mechanism for promoting angiogenesis may be related to the improvement of the protein expressions of VEGF and bFGF, so as to increase the contents of VEGF and bFGF and promote the angiogenesis of new vessels.

To study the chemical constituents of the inflorescences of Coreopsis tinctoria from Xinjiang, isolation and purification of constituents were carried out by column chromatography on macroporous resin (D101) , MCI gel, MDS gel, silica gel, Sephadex LH-20 and semi-preparative HPLC. The structures of the compounds were identified by physicchemical properties and spectral data analysis. Fourteen compounds were isolated and identified as coretinterpenoid A (1), coretinphenol (2), quercetin (3), quercetin-3-O-β-glucopyranoside (4), luteolin (5), taxifolin (6), 7, 3', 5'-trihydroxyflavanone (7), isookanin (8), isookanin-7-O-β-D-glucopyranoside (9), 5, 7, 3', 5'-tetrahydroxyflavanone-7-O-β-D-glucopyranoside (10), butein (11), okanin (12), sulfuretin (13), and linocinnamarin (14). Compound 1 was a new isabolane-type sesquiterpenoid and compounds 4, 10 and 13 were isolated from this plant for the first time.

OBJECTIVETo analyze the relationship of anxiety state with CD4(+) level and CD4(+)/CD8(+) ratio and to observe the effect of Chinese medicine (CM) treatment on anxiety in chronic hepatitis B (CHB) patients.

METHODSThe anxiety state of 120 CHB patients was evaluated based on Hamilton Anxiety Scale (HAMA) scoring. According to the scores, 63 patients with scores ≥14 were classified to anxiety and 57 patients with scores <14 to non-anxiety. The differences in CD4(+) cells and CD4(+)/CD8(+) ratio between patients with anxiety and non-anxiety were analyzed. Moreover, 63 patients with anxiety were randomized into two groups: 31 in the control group were treated with lamivudine (100 mg per day) alone and 32 in the observation group were given equal dosage lamivudine combined with CM treatment depending on syndrome differentiation, all for 12 weeks. The effects of treatment on anxiety state and T-lymphocyte subsets as well as its impact on some CHB-related indices were observed and compared.

RESULTSThe anxiety state of CHB patients was negatively correlated with CD4(+) and CD4(+)/CD8(+); the level of CD4(+) in patients with anxiety was significantly lower than that in non-anxiety patients (P<0.01 or P<0.05). After treatment, anxiety state in the observation group was significantly improved, with their HAMA scores significantly lowered (P<0.01), and the levels of CD4(+) and CD4(+)/CD8(+) were significantly higher than those in the control group (P<0.05 or P<0.01). Moreover, the alanine transaminase recovery rate and the HBV-DNA-negative conversion rate in the observation group were significantly higher than those in the control group, respectively (P<0.05).

CONCLUSIONSThe anxiety state of CHB patients was related to CD4(+) and CD4(+)/CD8(+) levels. CM treatment could improve the anxiety state and showed certain regulatory effect on the patients' immune system.
