OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.

METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.

RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).

CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

Objective To overcome the fact that SRV-NM virus can only multiple and amplify through partially pu-rified jaagsiekte retrovirus inoculated intratracheally in sheep but it cannot be augmented using in vitro cell culture, we con-structed JSRV-NM pseudovirions based on high efficiency packing system of lentivirus. Methods Lentivirus of three high efficiency packing plasmids system pMD.G, pCMV-HIV 8.2 and pHIV-eGFP was developed, and JSRV-NM-env coated plasmid pCMVJSRV-NM was used to substitute VSV-G virus coated plasmid pMD.G then co-transfected into 293T cells to replicate, package and produce restructured JSRV-NM pseudovirions. Gene expression of pseudovirion was determined through WPRE using real time PCR; Virus infectivity was detected through inoculating JSRV-NM pseudovirions into 24 pore plates. Results We construct JSRV-NM pseudovirions successfully based on the lentivirus system. JSRV-NM pseudo-virions can also be concentrated to higher titer (108 TU/mL detected by real time PCR by ultracentrifugation without signifi-cant loss of activity. JSRV-NM and VSV-G pseudovirions infected on Hela cells (both MOI= 3) respectively and no obvi-ous difference were shown on their infection efficiency detected by real time PCR. Conclusion Based on lentivirus system, JSRV-NM pseudovirions can be multipled and amplified in 293T cell culture in vitro. JSRV-NM pseudovirions is stable without loss its infection activity and the requirements of biological laboratory safety II was also met. JSRV-NM pseudoviri-ons will provide a useful tool for further study of JSRV-NM-env infection across species or its induction of lung adenocarci-noma.

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the expression of scavenger receptor A I (SR-A I) protein and mRNA in peritoneal macrophages of atherosclerosis (AS) rabbits. METHODS: A total of 26 New Zealand rabbits were used in the present study, among them, 7 were randomly selected to constitute a blank control group, and the rest 19 rabbits were fed with high-fat diet combined with carotid artery balloon injury for establishing AS model. Eight weeks after high-fat forage feeding, one high-fat fed rabbit and one normal rabbit were randomly selected for verifying the success of modeling. HE staining was employed to examine pathological changes of the common carotid artery after paraffin section. Then the rest 18 rabbits were randomly divided into model, EA and medication groups (n=6 rabbits in each). EA (2 Hz, 1 mA) was applied at "Guanyuan"(ST 25)and bilateral "Zusanli"(ST 36) and "Neiguan" (PC 6) for 20 min. The rabbits of the medication group were treated by gavage of Atorvastatin Calcium (1 mg•kg-1• d-1), and those of the model group treated by gavage of distilled water (2 mL•kg-1•d-1). The treatment was given once daily for 4 weeks, with one day's interval between every two weeks. Three days before termination of the experiments, sterile starch solution (3-4 mL/animal) was injected into the peritoneal cavity, and at the end of the experiment, the peritoneal fluid was collected and centrifugated to be cultivated in Dulbecco's Modified Eagle Medium (DMEM) for collecting the macrophages. The expression of SR-A I protein and mRNA in macrophages was assayed by Western blot and PCR, respectively. RESULTS: HE staining displayed an injury of the inner membrane of the carotid artery marked by observable atherosclerotic plaques, interruption, thickening and uplift, inflammatory cell infiltration, etc. in the AS model rabbits which were relatively milder in both EA and medication groups. The expression levels of SR-A I protein and mRNA were significantly up-regulated in the model group relevant to the blank control group (P<0.01), and considerably down-regulated in both EA and medication groups compared with the model group (P<0.01). There were no statistical differences between the EA and medication groups in the decreased levels of expression of SR-A I protein and mRNA (P>0.05). CONCLUSION: EA intervention may improve the severity of atherosclerosis to a certain degree in AS rabbits, which is possibly associated with its effect in inhibiting the expression of SR-A I protein and mRNA in the peritoneal macrophages.

OBJECTIVETo observe the effects of acupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) on distribution taxis of paclitaxel in mice with lung cancer to discuss targeted relationship between acupoints and corresponding viscera.

METHODSAccording to randomized digital table, 315 SPF-grade BALB/C female mice were divided into 7 groups: blank group (group A), model group (group B), medication group (group C), acupuncture at non-acupoint group (group D), acupuncture at Feishu group (group E), acupuncture at Lingtai group (group F) and acupuncture at Feishu and Lingtai group (group G), 45 mice in each one. Except the blank group, the remaining groups were treated with N-nitroso-tris-chloroethyl urea (NTCU) to establish the model of squamous-cell carcinoma. After model establishment, group A, group B and group C were not treated with acupuncture; group A and group B were treated with intraperitoneal injection of 0.9% sodium chlorvde solution by 6 mL/kg while group C was treated with intraperitoneal injection of paclitaxel by 6 mL/kg. The group D, group E, group F and group G were treated with acupuncture at non-acupoint, "Feishu" (BL 13), "Lingtai" (GV 10) and "Feishu" (BL 13) plus "Lingtai" (GV 10), respectively, then were intraperitoneally injected with paclitaxel by 6 mL/kg. The treatment was all given once a day for continuous 10 days. 15 min, 30 min, 1 h, 2 h, 8 h, 12 h and 24 h after the treatments, 6 mice in each group were randomly selected and sacrificed to collect samples of lung, liver, spleen, kidney and heart, etc. High performance liquid chromatography was applied to measure the concentration of paclitaxel in each organ (lung, liver, spleen, kidney and heart) at different time points.

RESULTS(1) The content of paclitaxel in lung, kidney and heart reached the peak at 2 h, then decreased significantly in group C, group D, group E, group F and group G; the content of paclitaxel in spleen showed downtrend at each time point. The content of paclitaxel in liver reached the peak at 2 h in group C and group D; the content of paclitaxel reached the peak at 8 h in group E, group F and group G. (2) The content of paclitaxel in lung in group E and group G was higher than that in group C and group D at each time point (all P < 0.01); the content of paclitaxel in lung in group F was higher than that in group C (P < 0.01) and group D (P < 0.01) only at time point of 2 h. The content of paclitaxel in lung in group G was higher than that in group F at each time point (all P < 0.05). There was no statistical difference between group G and group E (all P > 0.05).

CONCLUSIONAcupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) could influ- ence the metabolism of paclitaxel in lung-cancer mice, leading to distribution change in each organ. As a result, it could cause targeting effects, which is more significant at "Feishu" (BL 13) and "Lingtai" (GV 10).

OBJECTIVETo investigate the effect of sulindac on proliferation and apoptosis of human gastric cancer BGC-823 cells and its antineoplastic mechanisms.

METHODSHuman gastric cancer BGC-823 cells were incubated with sulindac at various concentrations and for different times. Morphological changes of BGC-823 cells were observed under an inversion microscope. MTT colorimetric assay was used to examine the effect of sulindac on the proliferation of BGC-823 cells. Flow cytometry was used to determine the cell cycle distribution and apoptosis. Transmission electron microscopy was performed to examine cell apoptosis morphology. Immunohistochemical staining was used to detect the expressions of COX-2, bcl-2 and ki-67 in the cells.

RESULTSsulindac induced morphologic alterations in BGC-823 cells, inhibited cell proliferation, increased the proportion of cells in G0/G1 phase and decreased the proportion of cells in S phase, induced apoptosis of BGC-823 cells, and decreased expressions of COX-2, bcl-2, ki-67 in the cells. All the effects were in a time- and dose-dependent manner (P < 0.05). Some characteristic morphologic features of apoptosis were revealed by transmission electron microscopy.

CONCLUSIONsulindac may inhibit the growth of gastric cancer BGC-823 cells in vitro and the anti-tumor mechanism may be related to changes in cell cycle distribution, induction of apoptosis and inhibition of expression of COX-2, bcl-2, and ki-67.

OBJECTIVETo investigate the treatment efficiency and mechanism of recombinant adenoviral vector carrying LRIG1 gene driven by Survivin promoter for bladder cancer.

METHODSHuman bladder cancer cell line BIU87 and immortalized human bladder epithelial cells SV-HUC-1 were infected with Ad-Surp-LRIG1 and Ad-LRIG, respectively. The selective infection efficiency of Ad-Surp-LRIG1 and Ad-LRIG were evaluated by checking the expression of epidermal growth factor receptor (EGFR). The MTT method was used to test cell growth inhibition ratio of Ad-Surp-LRIG1 and Ad-LRIG. Heterotransplanted models of human bladder cancer cell line BIU87 cells in nude mice were established. The mice were randomly divided into 3 groups during the experiment: Ad-Surp-LRIG1 group received viral supernatant solution of Ad-Surp-LRIG1 by tail vein injection; Ad-LRIG group received viral supernatant solution of Ad-LRIG by tail vein injection; and PBS group received phosphate buffer solution (PBS). The growth of tumors were observed and the growth curve was mapped. The expression of LRIG1 and EGFR were examined by reverse transcription PCR (RT-PCR).

RESULTSWhen Multiplicity of infection was 25, the transfection efficiency of Ad-Surp-LRIG1 was 74.56% in BIU87 cells and 0 in SV-HUC-1 cells (χ² = 58.640, P = 0.000), while the transfection efficiency of Ad-LRIG was 68.27% in BIU87 cells and 72.52% in SV-HUC-1 cells (χ² = 0.075, P = 0.784). The transfection efficiency difference of Ad-Surp-LRIG1 and Ad-LRIG in BIU87 cells was not statistically significant (χ² = 0.016, P = 0.898). Compared with PBS, Ad-Surp-LRIG1 and Ad-LRIG1 could inhibit BIU87 cell growth, the difference was significant in 4 days after transfection (F = 15.960, P = 0.000). There was not significant difference in cell growth rate of Ad-Surp-LRIG1 group and Ad-LRIG1 group. The tumor growth rate in Ad-Surp-LRIG1 group was slower than that in the other 2 groups. The tumor quality in Ad-Surp-LRIG1 was lighter than that in the other two groups, the differences were statistically significant (F = 97.860, P = 0.000), the quality difference in Ad-LRIG1 group and PBS group was not statistically significant difference (t = 1.73, P = 0.06). Compared with Ad-LRIG1 group and PBS group, the mRNA expression of LRIG1 was obviously up-regulated and that of EGFR was down-regulated in Ad-Surp-LRIG1 group (P < 0.01).

CONCLUSIONSThe recombinant adenoviral vector of Ad-Surp-LRIG1 could selectively transfected BIU87 cells, which could inhibit significantly the growth of bladder cancer in vivo and in vitro, the mechanism may be partly LRIG1 can downgrade the expression of EGFR.

OBJECTIVETo study the effect of selective moderate head cooling therapy on maximum length sequences brainstem auditory evoked potential (MLS-BAEP) in newborn piglets with hypoxic-ischemic brain damage.

METHODSSixteen newborn piglets aged 5-7 day old were randomly divided into three groups: normothermic control (n=4), HI (n=6) and mild hypothermia-treated (n=6). HI was induced through temporary occlusion of both carotid arteries, followed by mechanical ventilation with low concentration of oxygen (FiO2=0.06) for 30 minutes. Mild hypothermia was induced by equipment via circulating water. MLS-BAER was recorded before HI and at 12 hours, 24 hours, 36 hours, 48 hours, 60 hours, 72 hours, 4 days, 7 days, 10 days, 13 days and 15 days after HI.

RESULTSCompared with the normothermic control group, all latencies and intervals tended to increase significantly at 72 hours in the HI group and reached peak values on day 7. From day 10, all latencies and intervals tended to decrease, but apart from wave I latency, still differed significantly from those of the normothermic control group. MLS-BAER variables did not reach normal values until day 15. Ⅲ latency, Ⅰ-Ⅲ interval and Ⅰ-Ⅴ interval were significantly reduced in the hypothermia-treated group between 60 and 7 days after HI compared with the HI group (P<0.05). V latency and Ⅲ-Ⅴ interval in the hypothermia-treated group were also reduced compared with the HI group between 72 hours and 7 days after HI (P<0.05).

CONCLUSIONSBoth peripheral and central auditory systems are disturbed by HI, which shows as a significant increase in MLS-BAER variables (all latencies and intervals) in newborn piglets. Involvement in central brainstem auditory system reaches a peak on day 7 after injury. MLS-BAER variables still cannot reach to normal values until day 15. Selective moderate head cooling therapy can significantly reduce brainstem damage induced by HI.
