OBJECTIVETo study the effects of graphene quantum dots (GQDs) on hematopoietic system in rats.

METHODSThirty male SD rats were randomly divided into three groups (n = 10): control group, high dose group (10 mg/kg · d), low dose group (5 mg/kg · d), The rats in experimental group were intravenous injected with GQDs for 28 days and those in control group were injected with normal saline at the same volume. Routine blood and the function of liver and kidney were detected by instrument analysis. The cycle and apoptosis of bone marrow mononuclear cells (BMCs) were detected by FCM. The other three only healthy male SD rat bone marrow mononuclear cells (BMCs) were cultured by joining GQDs for 24 h, 48 h,72 h in vitro, the proliferation was assayed by CCK-8, the content of granulocyte macrophage colony stimulating factor (GM-CSF) from cultural supernatants were detected by ELISA.

RESULTSThe amount of red blood cell and concentration of hemoglobin from experimental group were increased significantly compared with those of control groups (P < 0.05), the concentration of triglyceride and high density lipoprotein were decreased. DNA synthesis period was prolonged (P < 0.01), there was no significant difference in apoptosis. BMCs were promoted proliferation clearly after using GQDs for 72 h (P < 0.05). The content of GM-CSF was increased (P < 0.01) .

CONCLUSIONGQDs may promote hematopoietic function in rats.

Objective:To investigate the oral-maxillofacial pain and t he surface electromyographic (EMG) activity of masseter muscles and anterior and posterior portions of temporalis muscles after experimental interference. Methods:A cast onlay of 0.5 mm in height was placed on the right low er first molar and remained for three days in 10 adult volunteers with normal oc clusion and without any symptom of TMD. The oral-maxillofacial pain was continu ously scored on a visual analogue scale(VAS)by the subjects before and after t he placement of the onlay. At the same time, the integral data of surface EMG we re recorded, and then the asymmetry index of the activity of bilateral muscles w as calculated. Results:Three days after the placement of the occ lusal highspot, all the subjects complained oral-maxillofacial pain. 8 of them had headache in right temporal region with VAS value of 1~4; the activity of tem poralis anterior at rest position of mandible was increased significantly (P

The aim of this study was to detect the localization and level of tyrosine phosphorylated proteins during in vitro capacitation of guinea pig sperm. Sperm from mature guinea pigs were incubated in modified TALP under 5% CO_2 in air at 37 ℃. The capacitation effect was assessed by chlortetracycline (CTC) staining. Western blotting and indirect immunofluorescence were used to analyze the level and localization of tyrosine phosphorylation. The results showed that guinea pig sperm underwent a time-dependent increase in protein tyrosine phosphorylation during the in vitro capacitation and the percentage of protein tyrosine phosphorylated sperm increased from 36% to 92% from the beginning of incubation to 7h incubation. Also, there was a shift in the site of phosphotyrosine-specific fluorescence from the head of sperm to both the head and the flagellum of sperm. Moreover, there were three proteins phosphorylated in this experiment. After 0 to 0.5h incubation, the protein of 40kDa was detected by anti-phosphotyrosine monoclonal antibody, and the intensity of this protein increased in the following incubation. Then, after 1h incubation, another protein of 80kDa was found and the level of this protein reached the highest point at 3h. Also, in 3h incubation, a protein of 45kDa was detected and the intensity of this protein increased in the following incubation.

Objective To determine the sensitivity and specificity of anti-cyclic citrullinated peptide antibodies (anti-CCP antibodies) in the diagnosis of rheumatoid arthritis. Method A total of 1018healthy donors, 212 patients with rheumatoid arthritis, 435 patients with other connective tissue disease were recruited to this study. Anti-CCP antibodies and IgM-rheumatoid factor (RF) were determined by ELISA according to manufacturer instructions, with a cut-off of 20U. Result The frequency of positive anti-CCP antibodies in patients with rheumatoid arthritis is 48.1% (n = 102 ), higher than healthy donors (2.6%,n = 26) and patients with other connective tissue diseases (3.7%, n = 16). The specificity of anti-CCP antibodies is 97.4%. The titer of anti-CCP antibodies in patients with rheumatoid arthritis (429. 7 U) is much higher than that in healthy donors (29. 3 U ) and patients with other connective tissue diseases (36. 5 U). The frequency of positive IgM-RF in patients with rheumatoid arthritis is 94. 3% whilst only21.5% in healthy donors. The false positivity rate of IgM-RF is higher than anti-CCP antibody. Conclusion Anti-CCP antibodies is a highly specific autoantibody in the diagnosis of rheumatoid arthritis.

Objective:To evaluate the effectiveness and safety of butyl phthalide capsules combined with Xueshuantong injection in the treatment of acute cerebral infarction (ACI). Methods: Cochrane Library, Medline, Embase, SCI, CBM, CNKI, VIP and Wanfang databases were searched from the building time to May 2016. The enrolled randomized controlled trails were studied by using Cochrane system evaluation methods to perform methodological quality assessment, and RevMan 5. 2 software was used to carry out Me-ta-analysis. Results:A total of 7 randomized controlled trails including 640 patients were enrolled. The results of Meta-analysis dem-onstrated that the effective rate of butylphthalide capsules combined with Xueshuantong injection was superior to that of Xueshuantong injection (RR=1. 33, 95%CI:1. 16-1. 52, P<0. 0001), butylphthalide (RR=1. 45, 95%CI:1. 15-1. 83, P=0. 002) and blank control (RR=1. 31, 95%CI:1. 08-1. 57, P=0. 005). NHISS of butylphthalide capsules combined with Xueshuantong injection was higher than that of Xueshuantong injection (MD=4. 63, 95%CI:3. 38-5. 87, P<0. 00001) and blank control (MD=6. 85, 95%CI:4. 90-8. 80, P<0. 00001). There was no significant difference in adverse drug reactions. Conclusion: Butylphthalide capsules combined with Xueshuantong injection is effective for the therapy of ACI. However, due to the limited quantity and quality of the in-cluded studies, larger scale trials are needed.

OBJECTIVE To investigate the effect of Turkish galls extract (TGE) on the expression of IgA in serum,urine and renal tissue of IgA nephropathy (IgAN) model rats.METHODS Fifty healthy male Sprague Dawley rats were randomly divided into normal control group,IgAN model group,and TGE 75,150 and 300 mg· kg-1 groups,10 rats per group.The model of IgAN rats was established with bovine serum albumin (BSA)+lipopolysaccharide (LPS)+carbon tetrachlorid (CCl4)for 12 weeks.From the 13th week,TGE was ig administrated once a day for 4 weeks.At the end of the 12th and 16th weeks,24 h urine protein was measured by BCA method.At the end of the 16th week,serum and urinary IgA levels were measured by enzyme linked immunosorbent assay(ELISA),serum creatinine(SCR) and blood urea nitrogen (BUN) were detected by an automatic biochemical analyzer,and the renal pathological changes were evaluated with an Oxford classification scoring system.The deposition of IgA immune complex in the kidney was observed by immunofluorescence assay.RESULTS At the end of 12th week,24 h urine protein increased in all IgAN groups (P＜0.05),compared with normal control group.At the end of 16th week,24 h urine protein,IgA content in serum and urine,SCr and BUN content in serum,score in Oxford classification of renal tissue and deposition of IgA immune complex in the kidney in IgAN model group were all higher than in normal control group (P＜0.05).Compared with IgAN model group,24 h urine protein,IgA content in serum and urine and SCr content in serum were decreased in all TGE groups (P＜0.05),and BUN content in serum and deposition of IgA immune complex in the kidney decreased in TGE 150 and 300 mg·kg-1 groups (P＜0.05).The score in Oxford classification of renal tissue was decreased in TGE 300 mg· kg-1 group only.CONCLUSION TGE has curative effect on IgAN model rats by reducing serum and urinary IgA and decreasing IgA immune complex deposition.
