Ribosome inactivating protein(RIP) is a kind of toxin plant pr ot ein in which extensively lives in the body of higher plants and controls ribosom e's function. Beside it can control protein's combination,it has lots of biolog ical reactivity as resisting giving birth and tumor and controlling HIV. At fir st, RIP is isolated from seeds of bitter melon.The result of SDS-PAGE indicate s that there are lots of RIP in the abstraction liquid.Then we study the antivi ral action of RIP through the cell of CEF and SPF chicken embryos.The results s how that RIP can resist NDVF_48E_8,MDVCVI_988 and FPV-SD4 to so me extent.

The teaching status of Molecular Pharmacognosy in 28 institutions in China was investigated by questionnaire and the survey data was analyzed by SPSS. Research contents included course beginning years, majors, class hours, characteristics of the course, teaching ways, the theory and practice contents, evaluation modes, selection of teaching material, teaching achievements, teachers and so on for undergraduates and graduates. Research results showed that with 20 years' development, Molecular Pharmacognosy had been offered for both undergraduate and graduate students in at least 20 colleges and universities and Molecular Pharmacognosy education in China showed good development momentum. At the same time, to promote the development of Molecular Pharmacognosy further, investment for it should be increased and practical teaching condition should be improved.

Objective:To investigate frequencies of microsatellite instability(MSI)and loss of heterozygosity(LOH)in renal ceil carcinoma(RCC),and to discuss the relationship of clinicopathological characteristics of RCC with MSI and LOH. Methods:Twelve microsatellite markers located at chromosomes 3p,9p and 14q were selected to investigate microsatellite alterations(MSI and LOH)in 31 RCC specimens and their paired metastasis specimens by polymerase chain reaction- polyacrylamide gel elect rophoresis-ethylene dibromide(PCR-PAGE-EB)staining and sequencing.Results:The frequency of MSI could reached 61.3% and that of LOH could reach 54.8%.The highest frequency of MSI was at locus of D9S168(32.3%);the highest frequency of LOH was at locus of D3S1289(21.4%).No correlation was found between MSI or LOH and the patients' age,sex,pathology type and metastastis,except that MSI was correlated with TNM stage of RCC(P

AIM: To observe the effects of porous polyethylene ( Medpor) as a spacer graft in the reconstruction of large areas eyelid defect after the operation of malignant tumors of lower eyelids.
METHODS: Nineteen cases ( 19 eyes ) of malignant tumors of lower eyelid underwent the eyelid reconstruction were selected. Medpor lower eyelid inserts implantation were used to replace tarsal joint sliding conjunctival flap and pedicle flap, and repaired full -thickness lower eyelid defects then underwent eyelid reconstruction.
RESULTS: Appearance of eyelids and functional improvements were satisfactory with no stimulation on the eyeball and no effect on the visual function. Implants is with no absorption, shift, exclusion or infection and no tumor recurrence in all cases during the follow up for 6-36mo.
CONCLUSION: Medpor lower eyelid inserts implantation can instead tarsal plate for the reconstruction of medium to large areas lower eyelid defect, which is easy performing with rare complications. It is an ideal alternatives of tarsal plate.

Nerve growth factor(NGF) was firstly discovered as a member of neurotrophin family,and the research and development of NGF has been lasting more than fifty years since its discovery.To this end,a two-step and high –yield chromatographic method which consists of cation ion-exchange chromatography and reversed-phase chromatography was reported to isolate recombinant human beta nerve growth factor(? –NGF) secreted by constructed Chinese hamster ovary cells(CHO/dhfr-) from the culture media.Through the process of purification,the purity of protein which was determined by SDS-PAGE and RP-HPLC has reached to 95%,and the recovery of ? –NGF routed by RP-HPLC could be 70%.Furthermore,the biological activity of final purified protein evaluated by PC12 cells and dorsal root ganglia(DRG) exhibited the same performance as the standard protein of ? –NGF bought from Sigma,which indicated that there is no loss of biological activity through the isolation process.The conclusion suggested that an economical isolation method of recombinant human ? –NGF could be practiced on the industrial process of purification.
8.Effect of medicated bath plus acupoint massage on limbs in treating 42 patients with diabetic peripheral neuropathy.
Chinese Journal of Integrated Traditional and Western Medicine 2006;26(11):1026-1028
OBJECTIVETo observe the effect of medicated bath plus acupoint massage on limbs (B-M treatment) in treating diabetic peripheral neuropathy (DPN).
METHODSEighty-two patients were divided into two groups, the control group (n=40) and the treated group (n=42), they were treated by conventional treatment but with B-M treatment applied to the latter additionally, the course to both groups was 12 weeks. The curative effects obtained were compared after treatment.
RESULTSThe total effective rate was higher in the treated group than that in the control group (81.0% vs. 52.5%, P < 0.05); the nerval transmission speed was improved significantly (P < 0.05) after treatment in both group, but that in the treated group was better than in the control group (P < 0.05).
CONCLUSIONB-M treatment on limbs has better effect than Western medicine along in promoting DPN restoration.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

Objective To construct PPAR?and PPAR?response element (PPRE)-controlled luciferase expression vectors,and to determine whether the traditional Chinese medicine emodin activates PPAR?and improves the glucose uptake by HepG2 hepatocytes.Methods (1) PPAR?and PPRE luciferase expression vectors were constructed and were applied to screen more than 20 ingredients of the traditional Chinese medicine. (2) HepG2 cells were incubated with emodin which can activate PPAR?and PPRE luciferase activity,and the PPAR?mRNA expression level was evaluated by RT-PCR/Southern blot.(3) PPAR?and glucose transporter 2 (Glut2) proteins were determined by Western blot analysis in HepG2 cells treated with emodin.(4) The glucose uptake rate was measured using 2-deoxy-[~3H]-D-glucose in HepG2 cells after treatment with emodin.Results (1) Emodin stimulated luciferase activity controlled by PPRE in dose-dependent manner at concentrations of 0.04 to 180?mol/L in COS-7 cells.The highest value was about 4 folds of control in the cells treated with 90?mol/L emodin (P
