AIM:To investigate the influence of matrine (MA) on the phenotype switching of mouse mono-cytes and alveolar macrophages induced by bleomycin ( BLM) .METHODS:All mice were randomly divided into normal saline (NS) group, BLM group, BLM+NS group and BLM +MA group.The mice were administered with BLM at 2.5 mg/kg via oropharyngeal instillation .The mice in BLM+MA group were treated with MA (15 mg· kg-1 · d-1 ) by oral gavage following BLM administration .The mice were sacrificed on days 3, 7, 14, and 21.The lungs were removed for pathological analysis .The circulating monocyte subsets and polarization state of bronchoalveolar lavage fluid ( BALF)-de-rived alveolar macrophages were analyzed by flow cytometry .RESULTS:The results of HE and Masson trichrome staining in BLM and BLM+NS groups exhibited classical pathological stages of lung fibrosis , including acute inflammation phase and later fibrosis phase .Compared with BLM +NS group, MA treatment alleviated the inflammatory response and the de-gree of fibrosis induced by BLM (P<0.05).There was a rapid change of circulating Ly6Chi monocytes and its magnitude was positively associated with the pulmonary inflammatory response .An expansion of M2-like alveolar macrophages was positively correlated with the magnitude of lung fibrosis .Moreover , MA treatment partially normalized the phenotype switc-hing of monocytes and alveolar macrophages .CONCLUSION:Matrine treatment attenuates BLM-induced pulmonary injury partially via modulating the phenotype switching of monocytes and alveolar mocrophages .

Artemisia lactiflora is an important medicinal plant in China. The antitumor and antioxidant activities of the extracts of 54 endophytic fungi from the plant were screened via MTT assay and DPPH scavenging radical assay, respectively. The bioactive strains were identified based on similarity of 5.8S gene and internal transcribed spacer (ITS) sequences. The results showed that extracts from ten (18.5%) isolates exhibited antitumor activity, and which from two (3.7%) isolates exhibited antioxidant activity. The Alternaria sp. GYBH47 strain was simultaneously having antagonistic activity against HL-60 leukemia, MCF-7 breast and COLO205 colon cell lines, and Phomopsis sp. GYBH42 strain having cytotoxic and antioxidant activities. The results indicated that endophytic fungi from Artemisia lactiflora are potential resources to find valuable bioactive components.

AlM:To observe the relationship between axial length and complications of phacoemulsification with intraocular lens ( lOL) implantation in high axial myopia eyes and normal axis eyes.
METHODS: A retrospective review of 843 consecutive patients ( 1 042 eyes ) of cataract extraction with phacoemulsification and lOL implantation in our hospital from February 2012 to February 2013 was performed. The patients were divided into two groups according to the axial length: 853 eyes were in normal axis group ( 21-24mm) and 189 eyes were in high axial myopia group (≥26mm). The two groups were compared regarding surgical complications, such as vitreous loss, posterior capsular rupture, nucleolus drop, and abnormal location of lOL.
RESULTS:Age was a risk factor in both groups. There was positive correlation between age and surgical complications, and between axial length and surgical complications, especially for complications with posterior capsular rupture and vitreous loss.
CONCLUSlON:As the results illustrate, in this survey, age and high axial lengthare statistically significant risk factors for incidence of complications of phacoemulsification. Anticipation of these complications and also preparation and prophylactic measures may decrease incidence of these complications.

To synthesize aristolochic acid (AA)-2'-deoxyguanosine 5'-monophosphate (dGp) adducts in vitro and develop a novel method for the characterization of the adducts using multiple mass spectrometric techniques. AA was incubated with dGp in vitro using either enzymatic activation (by xanthine oxidase) or chemical activation (by zinc) to synthesize AA-dGp adducts, and the reaction conditions were optimized. Crude extracts were analyzed by techniques of liquid chromatography-electrospray ionization/tandem mass spectrometry (LC-MS/MS) and high accuracy mass data and isotope pattern of super high resolution Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICRMS). The quasi-molecular ion peaks of the AA-dGp adducts were obtained in the negative ion mode. Analysis by electrospray ionization/tandem mass spectrometry (ESI-MS/MS) provided useful structural information about AA-dGp adducts. AA can bind covalently to the exocyclic amino group of deoxyguanosine to form AA-dGp adducts. MS analysis is a powerful tool to detect and identify AA-dGp adducts simply, rapidly and accurately.

OBJECTIVETo evaluate the randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention (PCI) with Chinese medicine adopting the principle of evidence-based medicine (EBM).

METHODSPertinent literatures were retrieved roundly, and scored depending on Jadad Quality Scale. Meta-analysis was applied on the total effect of outcomes reported using RevMan 4. 2 software. Moreover, the sensitivity was analyzed, the publication bias was identified with funnel-plot and the adverse reaction of medicine was reported.

RESULTSAmong the 17 literatures met the inclusion criteria, only two double-blinded trials were appraised as high quality. The analysis on the recurrence rates of restenosis post-PCI and angina pectoris in patients treated with Chinese medicine illustrated that the rates in the treatment group were all lower than those in the control group with statistical significance (P < 0.01). Sensitivity analysis revealed a relatively stable result of the evaluation. Funnel-plot displayed an asymmetrical figure, indicating the possible existence of publication bias.

CONCLUSIONTCM has definite therapeutic effect on preventing and treating restenosis after PCI and reducing the recurrence rate of angina pectoris in patients.

Objective To study the effects of different levels of iodine concentration on insulin-like growth factors Ⅰ (IGF-1) mRNA expression of thyroid and breast in lactating rats. Methods Thirty Wistar female rats, having been weaned for 1 month, were randomly divided into three groups according to their body weights, i. e. :low iodine(LI) group,adequate iodine(AI) group, high iodine(HI) group, 10 rats in each group. Synthetic fodder and deionized water containing iodine of 0,150,3000 μg/L was respectively fed to these rats. After fed for 3 months, the rats mated and had offspring. Their mammary glands, thyroids and serum were sampled at lactation day 5. The serum iodine of lactating rats were determined by moderate acid digestion method, level of T3 and T4 were determined by radioimmunoassay method, and the expressions of IGF-1 mRNA of mammary glands and thyroids were determined by real-time fluorescence quantitative PCR assay. Results The value of serum iodine of LI group [(17.38±3.27) μg/L] was lower than that of AI group [(43.42±6.92) μg/L, P<0.05], and the value of serum iodine of HI group[(350.10±38.46)μg/L] was higher than that of AI group (P<0.05). The level of T3 of LI group and HI group[ (1.11±0.25), (1.61±0.33)μg/L] reduced obviously compared with that of AI group[(2.18±0.46) μg/L, P<0.05]. The mean of T4 of LI group and HI group[(33.40±11.11),(56.54±10.38)μg/L] had no statistical significance compared with AI group(44.02±12.51)μg/L, P>0.05), but the level of T4 of LI group was lower than that of HI group(P<0.05). The level of IGF-1 mRNA expression of thyroid in LI group and HI group (0.34±0.08, 0.23±0.08) was higher than that of AI group(0.15±0.03, P<0.05). The level of IGF-1 mRNA expression of lactating mammary in LI group(0.59±0.18) was higher than that of AI group(0.40±0.10, P<0.05). The level of IGF-1 mRNA expression of thyroid was lower than that of breast between the same group(t=3.54, 6.44,2.62, all P<0.05). Conclusion Iodine could affect IGF-1 mRNA expression of thyroid and lactating mammary, and IGF-1 mRNA expression of lactating mammary was stronger than that of the thyroid.
