Comrade LU Zhi-jun, a famous surgeon and acupuncture expert, was a leading cadre in health field with outstanding achievements, and a leader of western medicine doctors learning traditional Chinese medicine in the Chinese Communist Party, and also he was a main establisher of The China Academy of Chinese Medical Sciences and a founder of TCM scientific researches and integrated Chinese and western medicine in new China. The present paper reviews the course of LU Zhi-jun in learning and applying acupuncture and moxibustion therapy and a part of works carried out in faithfully implementing our party's policies for uniting Chinese and Western medicine, and in development of TCM including acupuncture and moxibustion in past tens years.

Objective To study the MRI findings and di agnostic value as well as pathological base of the knee iniury.Methods MRI features of knee injuries in 31 cases were r etrospectively analysed compared with the findings of operations and clinical ma nifestations.Results MRI findings were :(1)para-knee articular soft tissue swelling in 23 cases(74%);(2)MRI detected ligaments injury in 18 cas es (58%),dislocation of articular in 2 cases(6%);(3)bone contusions in 4 c ases(13%);occult fractures in 1 case(3%),disruption of articular cartilage 1 case(3%),fractures in 12 cases(39%);(4)meniscal injury in 15 cases(48% ),meniscal cyst in 2 cases(6%);(5)quadriceps femoris and kneecap tendon inj ury in 1 case(3%)respectively;(6)joint hydrocele in 29 cases(93%).Conclusion MRI can find a variety of pathological changes of knee injury and plays an important role in clinical treatment and predicting prognosis.

Objective To explore a new molecular target for HSV-tk/GCV system in human liver cancer therapy.Methods The lactose and poly-L-lysine covalently linked compound(Lac-PLL) were prepared by using reductive amination methods and purified by using Sephadex G10 gel filtration.The value of n was determined by methods of phenol-vitriol colorimetry.The plasmid r-pAs16Dr was mixed with the conjugate to form a gene delivery complex named GlanPLL-r-pAs16Dr.The GlanPLL-r-pAs16Dr was transformed to different cell lines such as HepG2 and A549 to confirm the expression of RFP.The expression of HSV-tk was confirmed by RT-PCR.Cells with various concentrations of GCV were observed at different time points using MTT.Results The PLL modified by 34 Lac was obtained by using chemical synthesis.The RFP was expressed in HepG2 by 48h after transfection,and was not expressed in A549.The expression of HSV-tk was only detected in HepG2 using RT-PCR.The HepG2 transformed with GlanPLL-r-pAs16Dr was sensitive to GCV and the growth inhibiting rate was 70.5% with the treatment of low concentration of GCV(1mg/L) for 3 days.The A549 was not sensitive to GCV.Conclusion Lac-PLL,which is easy to prepare,is an efficient carrier for HSV-tk to be delivered to hepatoma cell lines by binding to ASGPR.

ATP-binding cassette transporter A1 (ABCA1) and scavenger receptor class B type I (SR-BI/CLA-1) are the key proteins in reverse cholesterol transport (RCT). The high expression of ABCA1 and SR-BI/CLA-1 can decrease the danger of atherosclerosis. The purpose of the study is to find ABCA1 and CLA-1up-regulators for treating atherosclerosis by using cell-based high throughput screening models. Among 20 000 compounds screened, E0869 [1-(3, 4-dimethylphenyl)-1-oxopropan-2-yll4-((methylsulfonyl)methyl)benzoate] was found as the positive hit. The up-regulated activities of E0869 in ABCAl1-LUC and bCA-l1-LUC HepG2 cell were 160% and 175%, respectively. The EC50 values of E0869 in ABCAl1-LUC and CLA-l1-LUC HepG2 cell were 3.79 and 1.42 pμol- x ,(-1) respectively. E0869 could upregulate the mRNA and protein levels of ABCA1, SR-BI/CLA-1 and ABCGJ1genes in HepG2 and RAW264.7 cells by Real-Time Quantitative PCR and Western blotting analysis, but could not influence the expression of FAS, SREBP-l1 and CD36. Foam cell assay showed that E0869 could inhibit lipids accumulation in mouse peritoneal macrophages RAW264.7. Cholesterol efflux assay showed that E0869 could induce HDL-mediated cholesterol efflux in mouse peritoneal macrophages RAW264.7. In conclusion, E0869 could up-regulate ABCA1 and CLA-1 activity, and had good anti-atherosclerotic activity in vitro.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

AIM: To investigate the mechanism of proliferation effect induced by (R,R)-XY-10 and (S,S)-XY-10 on retinal pigmented epithelial cells(ARPE-19).METHODS: Human retinal pigmented epithelial cells(ARPE-19) and human umbilical vein endothelial cells (HUVECs) were used to investigate the effect of (R,R)-XY-10 and (S,S)-XY-10 on cell growth,and their mechanisms of proliferative action by using ERK、 AKT、PI3K、Protein kinase C (PKC)and Nitric oxide synthase (NOS) inhibitors.RESULTS: (R,R)-XY-10 and (S,S)-XY-10 dose-dependently increased ARPE-19 cell proliferation,but not on HUVECs. When treated with proliferative inhibitors,H7(5μmol/L)、hypericin(20μmol/L)、PD98059(2μmol/L)、LY294002(50μmol/L)、SH-5 (10μmol/L) and L-NAME (100μmol/L),the proliferative effect was reduced by H7、hypericin、PD98059 and LY294002,but not by SH-5 and L-NAME.CONCLUSION: (R,R)-XY-10 and (S,S)-XY-10 can induce cell proliferation through MAPK and PI3K dependent pathway.
