OBJECTIVETo investigate the effect of four traditional Chinese medicines distributed along lung meridian, namely Ephedrae Hebra, Zingiberis Rhizoma, Scutellariae Radix and Mori Cortex, on TLR2 and NF-κB expressions in mice with lung heat syndrome, in order to study the intervention effect of the four traditional Chinese medicines (TCMs) on the lung heat syndrome.

METHODOne hundred KM mice were randomly divided into the normal control group, the model group, the Ephedrae Hebra group, the Zingiberis Rhizoma group, the Scutellariae Radix group and the Mori Cortex group (20, 10 g x kg(-1)), nasally dripped with streptococcus pneumoniae to establish the mouse lung heat syndrome model, and then administered with different TCMs. The expressions of TLR2, NF-κB p65 proteins in lung tissues were analyzed by the immunohistochemical method. The expressions of TLR2, NF-κB p65 mRNA were measured by real time PCR.

RESULTCompared with the normal control group, the expressions of TLR2 and NF-κB p65 proteins in lung tissues in the model group were higher (P < 0.01), and the expressions of TLR2 and NF-κB p65 mRNA in lung tissues were up-regulated (P < 0.01 or P < 0.05). Compared with the model group, Ephedrae Hebra high and low dose groups, the Zingiberis Rhizoma low dose group and the Scutellariae Radix high dose group showed decreased expression of TLR2 protein (P < 0.05 or P < 0.01); Ephedrae Hebra high and low dose groups, the Zingiberis Rhizoma low dose group, Scutellariae Radix high and low dose groups and Mori Cortex high and low dose groups showed reduced expression of NF-κB p65 protein (P < 0.05 or P < 0.01). Ephedrae Hebra high and low dose groups, Zingiberis Rhizoma high and low dose groups, Scutellariae Radix high dose group and Mori Cortex high dose group showed down-regulated expression of TLR2 mRNA (P < 0.01 or P < 0.05).

CONCLUSIONEphedrae Hebra, Zingiberis Rhizoma, Scutellariae Radix and Mori Cortex can induce the TLR2/NF-κB inflammatory signal pathways by down-regulating the expressions of TLR2 and NF-κB p65 in protein and mRNA, so as to alleviate the lung tissue injury in mice with lung heat syndrome.

AlM: To evaluate the effectiveness and security of lift and squeeze technique in phacoemulsification of hypermature cataract.
METHODS: From June 2010 to June 2013, totally 156 eyes with hypermature cataract, which received phacoemulsification in our hospital, were enrolled. Lift and squeeze technique was used to chop the nucleus, and 1g/L Trypan blue was used for capsulorhexis. Average time of phaco complication, corneal edema and visual outcome were recorded.
RESULTS: The best-corrected visual acuity ( BCVA ) was 0. 1-0. 4 in 15 eyes (9. 6%), 0. 5-0. 7 in 82 (52. 6%) eyes, and 0. 8-1. 0 in 59 ( 37. 8%) eyes at 3mo after surgery. The phaco time was 25-56s (average 42±10s), the maximum phaco power was 30%. Posterior capsular rupture and vitreous loss happened in 2 eyes (1. 3%), and the lOLs were implanted in the sulcus. Corneal edema classified at grade Ⅰ were seen in 12 eyes (7. 7%), and 5 eyes (3. 2%) at gradeⅡ, no eye at gradeⅢ and gradeⅣ. The mean endothelial cell loss was 8. 7%at 3mo.
CONCLUSlON: Crystalline lens capsule staining with Trypan blue increase the success rate of intact continuous curvilinear capsulorhexis ( CCC ) . The lift and squeeze technique reduces the stress on the zonules and capsule, and decreases the phaco time and phaco power.

OBJECTIVETo investigate the relationship between lamivudine-resistant mutants of hepatitis B virus (HBV) and serum HBV DNA loading before antiviral therapy.

METHODSThis study involved 106 patients with hepatitis B receiving lamivudine treatment for an average of 32 months (rang 12-48 months). Serum HBV DNA loadings were measured with PCR before and every 4 to 6 months during lamivudine therapy. HBV YMDD mutants were detected using mismatched PCR-restriction fragment length polymorphism (PCR-RFLP) during lamivudine treatment.

RESULTSHBV DNA loading was significantly higher in patients infected with HBV YMDD mutants during lamivudine therapy than those infected with HBV without YMDD mutation.

CONCLUSIONHigh viral loading in hepatitis B patients before treatment is associated with high likeliness of HBV YMDD mutation during lamivudine treatment. HBV DNA loading may be indicative for the occurrence of YMDD mutation during lamivudine therapy.

Background Posterior capsular opacification(PCO) is common complication after extrecapsular extract of cataract.Matrix metalloproteinases-3 (MMP-3) can degrade all the extracellular matrix except polyose.The gene therapy of PCO upon MMP-3 is the researching hot topic.Fibronectin ( FN ) is a degrade gelatin,so its expression can reflect the effect of MMP-3 on LECs indirectly. Objective The aim of this study was to construct MMP-3 eukaryotic recombination plasmid and transfect to lens epithelium cells(LECs) for the observation of MMP3 expression,and to explore the feasibility of gene therapy for after cataract. Methods Six fresh lenses were obtained from pigs.LECs were cultured using explant method.The eukaryotic expression vector pEGFP-N1-MMP-3 was reconstructed with MMP-3 and pEGFP-N1 plasmids.The accuracy of MMP-3 gene fragment was confirmed by double enzyme digestion and DNA sequencing analysis.After transfecting pEGFP-N1-MMP-3 into LECs of pig,the expression of MMP-3 protein in the cells was indirectly observed by green fluorescent protein.The expression of FN in LECs was detected using Western blot. Results The result of double enzyme digestion was consistent with the base number of pEGFP-N1 plasmids and target fragment.By enlacing the result of DNA sequencing analysis with software,the resemblance of the DNA sequence of MMP-3 from recombination plasmid pEGFP-N1-MMP-3 and that of homo MMP-3 was 99.6％,indicating that the target fragment was inserted to pEGFP-N1 plasmids successfully.Green fluorescence for GFP was seen in the LECs in pEGFP-N1-MMP-3 transfected group,but absent response for GFP was in empty vector group.Western blot revealed that the relative expression level of FN in LECs was 0.666±0.008 in pEGFP-N1-MMP-3 trasfected group and 0.326 ±0.071 in empty vector group,with a significant difference between these two groups(P=0.000). Conclusions Eukaryotic recombination plasmid pEGFP-N1-MMP-3 is successfully constructed,and MMP-3 can be expressed in LECs after transfected.These results lay a foundation for the further research of MMP-3 gene therapy for PCO.

BACKGROUND: Chinese traditional osteopathy is long in history, unique in manipulation and miraculous in therapeutic effect. But people understand it more m perception rather than in theory, more in application rather than in development. There is little research truly on the bioseience.OBJECTIVE: To probe into the macro-idea of Chinese traditional osteopathy, micro-mechanisms on characters and mathematics-physics models, aiming to provide new principles and approaches of treatment for the daily increased bone trauma, fracture and sport injury.SETTING: Physics and machine-electron college of a university, and its affiliated hospital.METHODS: Based on the natural concept of "integration between heaven and human being" and new concept of holistic medicine in Chinese traditional osteopathy, the macro-idea and characters of reduction and union of fracture are generalized from the characters of natural therapy and the biomechanical mechanisms and characters of reduction and union of fracture are summarized from the micro-reaction of bone repair and union so as to discover biomechanical mechanisms and characters of reduction and union of fracture and further to set up biomechanical models and mathematics-physics expressions during the treatment.RESULTS: Chinese traditional osteopathy envelopes macro-idea of "initiative reduction-functional union" in fracture and micro-mechanism on "stress adaptability-functional adaptability" of bone repair and union.CONCLUSION: Chinese traditional osteopathy compiles with the natural,green and non-traumatic therapy in bio-natural law of bone repair and union and supports the theme of "high thought and high skill".
