Objective To evaluate the incidence of net adverse clinical and cerebral events (NACCE) 1 year after implantation of biodegradable polymer stents (BP-SES) in elderly patients with coronary artery disease.Methods The clinical data of patients inserted with BP-SES in I-LOVE-IT 2 Trial were retrospectively analyzed, including 1829 elderly patients admitted in the General Hospital of Shenyang Military Command from Oct. 2012 to Jun. 2013, of which 62 cases aged equal to and more than 65 years (elderly group) and 1202 cases less than 65 years (non-elderly group). The primary end-point of this research was target lesion failure (TLF) rate on 12 months and the secondary end-point was the incidence of NACCE, including all-cause death, all myocardial infarction, stroke and severe hemorrhage (BARC type ≥3), and then the multiple regression analysis was performed.Results The Baseline conditions of the two groups were significantly different (P<0.05) including BMI, diabetes, hypertension, hyperlipidemia, family history of coronary heart disease, smoking history, past stroke history, history of peripheral vascular disease and stable angina pectoris. When comparing elderly group with non-elderly group, marked differences existed on the incidence of NACCE (10.0%vs. 5.2%,P<0.01), all-cause mortality (2.7%vs. 0.7%,P<0.01), myocardial infarction (5.6%vs. 3.5%,P=0.03), stent thrombosis (1.9%vs. 0.5%,P<0.01) and stroke (2.2%vs. 0.8%,P=0.01). Multiple regression analysis revealed that elderly (age ≥65) was the independent predictive factor for NACCE (OR=1.904, 95%CI 1.304-2.781,P=0.001).ConclusionThe incidence of NACCE is increased significantly in elderly patients (age ≥65), and elderly is an independent predictive factors for 12-month NACCE in patients implanted with BP-SES

The study is to report the establishment of a method of screening the antitumor compounds based on the dynamic bio-response profile of cells to make up for the shortages of conventional end-point tests such as tedious operation and low sensitivity. Based on the principle of electric impedance of cells, the real-time cell electronic sensing (RT-CES) system was used to monitor the effect of epirubicin (EPI), cisplatinum (DDP) and carboplatin (CBP) on the growth of HepG2 cells, with the cell index (CI), half maximal inhibitory concentration (IC50) and detachment curve as evaluation indexes. Meanwhile, cell counting kit-8 (CCK-8) and microscopy were applied for verification. The results showed that CI curve could sensitively real-time profile the inhibitory effect of model drugs on HepG2 cells. The IC50 of EPI, DDP and CBP were 0.53 +/- 0.04, 9.79 +/- 0.26 and 597.00 +/- 3.79 microg x mL(-1), respectively. What's more, the significant differences of detachment curves of the three drugs indicated that their functional mechanisms might be different, this is consistent with the literature. The RT-CES system with non-invasive, label-free and real-time characteristics could be used to monitor the bio-response profile of the three drugs to HepG2 cells, allowing to qualitatively and quantitatively distinguish the antitumor activities of the three drugs, and could be a complementary method for the present screening of antitumor compounds.

OBJECTIVE To investigated the regulatory effect of paeoniflorin-6'-O-benzene sulfonate (CP-25) on B cell activating factor (BAFF)/BAFF receptor-nuclear factor of kappa B (NF-κB) signaling in B cell of collagen induced-arthritis (CIA) mice. METHODS Mice CIA was induced by injection of typeⅡcollagen (CⅡ). The arthritis index (AI) and swollen joint count (SJC) were assessed, and histopathology of spleen and joints were observed. The percentage of B cells subsets, BAFF receptor expressions were analyzed by flow cytometry. BAFF and immunoglobulin (Ig) levels were measured by protein antibody array. The expressions of TRAF2, MKK3, MKK6, p-P38, and p-NF-κB65 in NF-κB signaling mediated by BAFF were analyzed by western blot. RESULTS CP-25 decreased AI and SJC, restored abnormal weights, reduced thymus index and spleen index, inhibited T/B cells proliferation, alleviated the histopathology of spleen and joints in CIA mice. CP-25 also reduced high levels of serum BAFF and immunoglobulin, decreased CD19+B cells, CD19+CD27+B cells, and CD19-CD27+CD138+ plasma cells, inhibited BAFFR and TACI expressions, decreased the expressions of TRAF2, MKK3, MKK6, p-P38, and p-NF-κB65. Compared with biological agents etanercept and rituximab, CP-25 restored high T cells proliferation and percentages of B subsets to normal level, and recovered the high levels of IgA, IgD, IgG1, IgG2a and high expressions molecules in NF- κB signaling to normal levels. The action intensity of rituximab and etanercept was more strong than CP- 25. The inhibitor effects of rituximab and etanercept on AI and SJC, thymus index, proliferation of T cells and B cells subsets were strong, and down-regulated the indexes to under normal levels. CONCLUSION CP-25 might be a promising anti- inflammatory immune and regulation drug, which alleviated CIA and regulated the functions of B cells through BAFF/BAFF receptor-NF-κB signaling.

OBJECTIVE This study was to investigate the effects of CP- 25 on the functions of activated human B cells through regulating BAFF and TNF-alpha signaling. METHODS B cells from peripheral blood mononuclear cells (PBMCs) of normal human were isolated using magnetic cell separation (MACS) by a positive selection. B cells (107 cells·mL-1) were stimulated by BAFF (100 ng·mL-1) or TNF-alpha (100 ng·mL-1) for two hours, and then were treated with CP-25 (10-5 mol·L-1) or Rituximab (5 μg·mL-1) or Etanercept (10 μg·mL-1). B cell proliferation was detected by CCK-8. B cell subsets and BAFF receptors (BAFFR, BCMA and TACI) were analyzed by flow cytometry. The expression of TNFR1 and TNFR2 on B cells was analyzed by flow cytometry. The expression of MKK3, MKK6, P-p38, P-p65, TRAF2 and p100/52 was analyzed by Western blotting. RESULTS CP-25 inhibited B cells proliferation stimulated by BAFF or TNF- alpha. CP- 25, Rituximab and Etanercept reduced the percentage and numbers of CD19+ B cells, CD19+CD20+ B cells, CD19+CD27+ B cells and CD19+CD20+CD27+ B cells induced by BAFF or TNF-alpha. CP-25 down-regulated the high expression of BAFFR, BCMA and TACI stimulated by BAFF or TNF-alpha. CP-25, Rituximab and Etanercept down-regulated significantly the expression of TNFR1 and TNFR2 on B cell stimulated by BAFF or TNF-alpha. CP-25, Rituximab and Etanercept down-regulated the expression of MKK3, P-p38, P-p65, TRAF2 and p52 in B cells stimulated by BAFF and the expression of TRAF2 and P- p65 in B cells stimulated by TNF-alpha. CONCLUSION CP- 25 regulated moderately activated B cells function by by regulating the classical and alternative NF-κB signaling pathway mediated by BAFF and TNF-alpha-TRAF2-NF-κB signaling pathway. This study suggests that CP-25 may be a promising anti-inflammatory immune and soft regulation drug.

OBJECTIVETo compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

METHODSOne hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups.

RESULTSThe total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05).

CONCLUSIONAcupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

OBJECTIVETo study into the genetic polymorphism of DC-SIGN and DC-SIGNR's exon 4 in Chinese hepatitis C patients and its relationship with HCV infection susceptibility.

METHODSPatients with hepatitis C (n=300, group A) and healthy subjects (n=520, group B) were genotyped and analysed for the repeat sequence of polymorphism of DC-SIGN and DC-SIGNR's exon 4 using PCR and DNA sequencing.

RESULTSThe distribution of genotypes and alleles in DC-SIGN's exon 4 in the two groups did not differ significantly (P > 0.05). The difference of allele frequency in DC-SIGNR's exon 4 between the two groups was also not significant (P > 0.05). However, 9/5 genotype distribution frequency of DC-SIGNR's exon 4 in patients with hepatitis C was significantly higher than that in the healthy subjects (P < 0.05).

CONCLUSIONThere is no significant correlation between the genetic polymorphism of DC-SIGN's exon 4 and HCV infection susceptibility. 9/5 genotype distribution frequency of DC-SIGNR's exon 4 in patients with hepatitis C is significantly higher and may be associated with HCV infection susceptibility.

OBJECTIVETo investigate the effects of taurine on myocardial mitochondria and their enzyme activities in rats with severe burn.

METHODSOne hundred and twenty healthy adult Wistar rats were subjected to 30% TBSA full-thickness burn. They were randomly divided into burn group (B, with intraperitoneal injection of isotonic saline), treatment group (T, with intraperitoneal injection of taurine, 200 mg/kg),with 60 rats in each group . Ten rats with sham scald were used as control (S group). The myocardial tissue samples in B and T groups were harvested at 1, 3, 6, 12, 24 and 48 postburn hours (PBH) for determination of activity respectively of succinate dehydrogenase (SDH), cytochrome oxidase (CCO), the superoxide dismutase (SOD), Ca2+ -ATPase in mitochondria, and contents of cytochrome c (Cyt c), cytochrome aa3 (Cyt aa3), malondialdehyde (MDA), and Ca2+ in mitochondria and cytoplasm . The myocardial tissue samples of controls were harvested at 1 PBH for determination of above indices.

RESULTSThe activity of CCO in B group was decreased at 1 PBH , especially at 6 ,12 PBH. The activity of SDH in B group was decreased to lowest level at 6 PBH, and its value was lower than that of S group at each time point. The activity of CCO or SDH in T group was not obviously decreased, and the activity of CCO at 3, 6, 12 PBH showed significant difference compared with B group (P < 0.05). The contents of Cyt aa3 and Cyt c in B group at 3, 6, 12, 24 PBH were obviously decreased, which were significantly lower than those in T group (P < 0.05). The activity of SOD in B group at 3, 6, 12 PBH was obviously decreased, the activity of Ca2+ -ATPase at 3, 6, 12 and 24 PBH was decreased to different extent, which was significantly lower than those in T group (P < 0.05). The MDA contents in B and T groups were higher than that in S group at 3-48 PBH ,and it was highest in B group (P < 0.05). The Ca2+ content of mitochondria in B group at 1 PBH was increased (13.7 +/- 1.5), and it was (24.8 +/- 2.6), (29.7 +/- 3.1), (16.3 +/- 1.9) and (13.5 +/- 1.7) at 3, 6, 12, 24 PBH respectively,and they were all higher than that of S group (10.7 +/- 1.6, P < 0.05). The Ca2 contents of cytoplasm in group B at 3 - 24 PBH were also higher than that in S group (P < 0.05). The Ca2+ content of mitochondria in T group at 3, 6, 12, 24 PBH was (16.8 +/- 2.8), (18.7 +/- 1.9), (10.5 +/- 1.8) and (13.3 +/- 1.7)respectively, which were lower than that in B group at every time point.

CONCLUSIONTaurine have protective effect on mitochondria and their enzyme activities in myocardium in rats with severe burn, and it may be attributable to improving the ability of eradicating oxygen free radicals and alleviating Ca2+ overload in the mitochondria.
