Aim: To study the synthesis and anti-platelet aggregation activities of ferulic acidic esters so as to search for novel antithrombus agents. Methods: Based on prodrug strategy and combination principles, monoesters were first synthesized by reaction of ferulic acid with alcohols, and then the monoesters were coupled with aspirin to afford bis-esters. The target compounds were assayed for anti-platelet aggregation activities in vitro. Results: Sixteen target compounds and eight sideproducts including 15 new compounds were synthesized and their struc-tures were determined by IR, MS and ~1H NMR. The results demonstrated that some tested compounds exhibited potential anti-platelet aggregation activities. Conclusion: The bis-esters of ferulic esters coupling with aspirin with 4 to 5 carbons in side chain might be used as lead compounds for further study in searching for novel antithrom-bus agents.

The effects of solvents, pressure/temperature of solvents and microwave radiation time on the yield of baicalin were studied by orthogonal experimental design. Results The optimal experimental conditions were extraction at 70% of microwave power with 30 times of 35% ethanol at a constant heating pressure/temperature of 0.15 MPa for 30 s. Conclusion The microwave assisted extraction not only takes a shorter time with better parallel results, but also gave an increased yield of about 10% as compared with ultrasonic extraction.

Objective: To investigate the effectiveness of cementless total hip arthroplasty (THA) in treatment of avascular necrosis of the femoral head (ANFH) in patients with human immunodeficiency virus (HIV) infection. Methods: The clinical data of 22 patients (35 hips) with HIV infection and ANFH (positive group), who were treated with cementless THA between February 2014 and January 2017, was retrospectively analyzed. Tirty-three cases (43 hips) without HIV infection, who were treated with cementless THA during the same period, were collected as control (negative group). There were significant differences in the age, gender, incidence of bilateral ANFH, and disease duration between 2 groups ( P<0.05). There was no significant difference in the Ficat stage of ANFH between 2 groups ( P>0.05). The operation time, intraoperative blood loss, rate of blood transfusion, postoperative complications, and hospitalization time were recorded. The hip joint function was evaluated by Harris score and X-ray film was performed to observe the position of the prosthesis. Results: The follow-up time was 13-24 months (mean, 20.2 months) in positive group and 14-25 months (mean, 21.6 months) in negative group. The operation time of negative group was significantly shorter than that of positive group ( t=3.677, P=0.001). However, there was no significant difference in intraoperative blood loss, rate of blood transfusion, and hospitalization time between 2 groups ( P>0.05). There was no significant difference in Harris score between 2 groups before operation and at 1, 3, 6, and 12 months after operation ( P>0.05). There were 2 cases of superficial infection of incision and 1 case of pulmonary infection during hospitalization in positive group, and 1 case of superficial infection of incision and 1 case of venous thrombosis of lower extremity in negative group. No death or loosening and sinking of the prosthesis occurred in both groups during follow-up. Conclusion: Cementless THA is a safe and effective method for ANFH in patients with HIV infection.

Objective To explore the relationship of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with gastrointestinal bleeding in adult patients with Henoch-Sch(o)nlein purpura (HSP).Methods Laboratory data including routine blood test results,C-reactive protein (CRP) levels and erythrocyte sedimentation rate (ESR) were collected from 115 adult patients with HSP and 100 healthy controls,and retrospectively analyzed.NLR and PLR were calculated and compared.Logistic regression analysis was used to determine variables associated with gastrointestinal bleeding in adult patients with HSP,and the receiver operating characteristic (ROC) curve was drawn to estimate the predictive efficacy of these variables.Results NLR and PLR were both significantly higher in adult patients with HSP than in healthy controls (both P ＜ 0.05),and NLR,PLR and CRP levels were all significantly higher in adult HSP patients with gastrointestinal bleeding than in those without (all P ＜ 0.05).Logistic regression analysis showed that NLR was an independent risk factor for gastrointestinal bleeding in adult HSP patients (P ＜ 0.05).The ROC curve revealed that the optimal cut-off point of NLR for predicting gastrointestinal bleeding was 3.24 in adult patients with HSP,with the sensitivity and specificity being 85.1％ and 71.3％ respectively.Conclusions Both NLR and PLR evidently increase in adult patients with HSP,especially in those with gastrointestinal bleeding.NLR is a potential predictor for gastrointestinal bleeding in adult patients with HSP.

Objective To investigate the effect of Candida albicans and its components on the expression level of human beta-defensin-2 mRNA (HBD-2) in keratinocytes in vitro. Methods Different components of Candida albicans were isolated by lyticase, repeated freezing and thawing, sonication, and centrifugation. The keratinocytes and HaCaT cell lines were co-cultured with Candida albicans and its cellular components for 24 h. The expression level of HBD-2 mRNA was detected by reverse-transcription polymerase chain reaction (RT-PCR). Results Low expression level of HBD-2 mRNA in the unstimulated keratinocytes and HaCaT cells was detected. The HBD-2 mRNA expression levels in the keratinocytes stimulated by Candida albicans, the extract of its cell wall, and pure mannan were significantly increased (P 0.05). Conclusions Candida albicans, the extract of cell wall of Candida albicans, and commercial mannan can increase the expression level of HBD-2 mRNA in keratinocytes.

The metabolic effect of Fo-Shou-San on blood deficiency mice was studied by using metabolomic method. UPLC-QTOF/MS was used to analyze the plasma metabolome in blood deficiency mice. MS data were processed by MarkerLynx software. With multivariate statistical analysis of plasma metabolite profiles, a clear separation among control, blood deficiency model, and Fo-Shou-San groups was achieved. Potential biomarkers were selected according to the parameters of variable importance in the projection (VIP) and identified according to MS information and database retrieval. The metabolic network of blood deficiency was predicted via MetPA database. Twenty-two potential biomarkers were identified and used to explain the thiamine metabolism, arachidonic acid metabolism, sphingolipid metabolism, glyoxylate and dicarboxylate metabolism, histidine metabolism, nicotinate and nicotinamide metabolism, cysteine and methionine metabolism, tryptophan metabolism, starch and sucrose metabolism, tyrosine metabolism and citrate cycle (TCA cycle). Those metabolic pathways were disturbed in blood deficiency mice, but which could be regulated nearly to normal state after Fo-Shou-San administration. In this study, the metabolomics of blood deficiency mice and the action mechanism of nourishing blood effect of Fo-Shou-San were evaluated. The physiological and metabolic state of the organism could be represented comprehensively by using metabolomics. And metabolomics can be used to evaluate the pharmacodynamics and related mechanisms of Chinese medicine and formulae.

The heterogeneity of high-density lipoprotein-cholesterol (HDL-C) in hyperuricemia was analyzed in Uygur,Han,and Kazak ethnic groups in Xinjiang.A total of 2 396 subjects were surveyed.The HDL-C levels were significantly decreased in hyperuricemia group compared with control group in Han and Uygur,while the reverse occurred in Kazak.The serum uric acid (SUA) level in Kazak was the lowest.The SUA was negatively correlated with HDL C in Kazak (P ＜ 0.05).HDL-C was a recognized protective factor for cardiovascular disease.With the lowered SUA level in the Kazak group,HDL-C level was increased.When SUA level was higher than a certain level (such as the SUA-4),there existed a negative impact on cardiovascular disease

The combination of Angelicae sinensis Radix (Danggui, DG) and Astragali Radix (Huangqi, HQ) is a popular herb pair commonly used in clinic for the treatment of blood deficiency syndrome in China. The aim of this paper is to study the interaction of DG and HQ nourishing and tonifying blood effects by response surface method. The blood deficiency mice were induced by injecting N-acetylphenylhydrazine (sc) and cyclophosphamide (ip). The blood deficiency mice were administrated intragastrically with DG-HQ extracts (0:1, 1: 5, 2:5, 2:3, 1:1, 3:2, 5:2, 5:1, 1:0). The changes of the peripheral blood indexes and organ indexes were observed. The indexes were integrated by comprehensive index method; the interactions of DG and HQ were analyzed by the response surface diagram established with Matlab software. The results showed that DG and HQ at most of their combination ratios had synergic effect. Within the range of 1:5 - 5:1, all of the extracts of DG-HQ showed synergic effect, and among which, high-doses had better effects than low-doses. The highest value (-1) of the synergic effect was showed when DG was 10 - 40 g at the same time of HQ as 90 -180 g, and DG was 50 - 100 g at the same time of HQ as 20 - 100 g. DG-HQ at all combination dosages within Chinese Pharmacopeia (DG: 6 - 12 g, HQ: 9 - 30 g) had certain synergic effect, and Danggui Buxue Decoction (DG: 6 g, HQ: 30 g) also was at this range. The results provided scientific basis to the clinical application of DG and HQ. And the response surface method was firstly applied to quantitatively evaluate the bio-activity change of herb combination, which provided a novel way for modern basic research on the interaction of herbs.
