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).

Objective To study Epstein-Barr vires infection and p16 protein abnormal expresson in carcinogenesis and progression of gastric adenocarcinomas (GAC). Methods Immunohistochemical staining SP method was used to detect the expression of LMP-1 and p16 in 97 cases of GAC. Results EBV LMP-1 and p16 protein were detected in 30.9% (30/97) and in 63.91% (62/97) cases of gastric adenocarcinomas respectively.There was no significant difference between EBV-positive and EBV-negative gastric carcinomas in sex, histologic type, depth of tumor invision, lymph node metastasis and clinical stages (P>0.05);overexpression of p16 was associated with lymph node metastasis and clinical stages; no correlation was found between the expression of EBV LMP-1 and p16 protein. Conclusion ①EBV play a role in carcinogensis of GAC. ②P16 gene abnormality is frequently involved in GAC and might be one of the important prognostic factors. ③EBV infection and p16 alteration are two independent roles in GAC carcinogenesis.

OBJECTIVE: To systematically review the effectiveness and safety of electroacupuncture (EA) on hyperlipidemia combined with atherosclerosis in animal experiments. METHODS: The relevant animal experiments of EA treatment for hyperlipidemia combined with atherosclerosis were retrieved from the CNKI, WANFANG, VIP, CBM, PubMed, Embase and the Cochrane Library up to March 19, 2018 since the establishment of databases. Two researchers in the project team screened the literature and extracted the information such as experiment objects, experiment steps and experiment results separately. The literature assessment was evaluated. Meta analysis was performed with RevMan 5.3 software. RESULTS: Eventually, 29 eligible experimental researches were included and the average score in the quality assessment was 5.1, at the moderate level. Meta analysis showed that compared with the model control group, after EA treatment, the levels of the total cholesterol (TC) [ -2.29, 95% (-2.94, -1.64), <0.000 01], triglyceride (TG) [ -1.30, 95% (-1.76, -0.84), <0.000 01] and low density lipoprotein-cholesterol (LDL-C) [ -2.64, 95% (-3.29, -1.99), <0.000 01] were significantly reduced and the level of high density lipoprotein-cholesterol (HDL-C) [ 0.55, 95% (0.06, 1.04), =0.03] was increased, indicating the significant differences. CONCLUSION On the base of the current limited evidences, EA significantly reduces the levels of TC, TG and LDL-C and slightly increases the level of HDL-C in the animal models of hyperlipidemia combined with atherosclerosis.

OBJECTIVE: To observe the effects of electroacupuncture (EA) at "Neiguan" (PC 6), "Guanyuan" (CV 4) and "Zusanli" (ST 36) on CYP7A1 expression in liver of rabbits with atherosclerosis (AS), and to explore the mechanism of acupuncture for prevention and treatment of atherosclerosis. METHODS: A total of 26 male rabbits were adaptively fed for 1 week in different cages. Seven rabbits were randomly divided into a blank group, and the remaining 19 rabbits were divided into a model group. The blank group was fed with normal diet, while the model group was fed with high-fat diet. After high-fat diet for 4 weeks, the rabbits in the model group were treated with balloon injury surgery of the common carotid artery; after surgery, the rabbits were fed with high-fat diet for 4 weeks. One rabbit was randomly selected from the blank group and model group to obtain the pathological section of carotid artery; the HE staining was used to observe the pathomorphology of atheromatous plaque to determine the success of modeling or not. After successful establishment of modeling, 18 rabbits were randomly divided into a AS model group, an EA group and a medication group, 6 rabbits in each one. The rabbits in the AS model group received no treatment; the rabbits in the medication group were treated with intragastric administration of atorvastatin calcium tablets; the rabbits in the EA group were treated with EA at "Neiguan" (PC 6), "Guanyuan" (CV 4) and "Zusanli" (ST 36), once a day, 20 min per treatment; six-day EA treatment constituted one course, and totally 4 courses were given with an interval of 1 day between courses. After treatment, vein blood was collected from rabbit ear, and cholesterol (CHO), triglyceride (TG), low-density lipoprotein (LDL) and high-density lipoprotein (HDL) were measured in each group; the CYP7A1 protein expression in rabbit liver was measured by Western blot method, and CYP7A1 mRNA expression in rabbit liver was measured by RT-PCR. RESULTS: Compared with the blank group, the contents of CHO, TG and LDL in the AS model group were significantly increased, but HDL was significantly decreased, and the expression of CYP7A1 protein and CYP7A1 mRNA in the liver were significantly decreased (all <0.01). After treatment, compared with the model group, the contents of CHO, TG and LDL in the EA group and medication group were significantly reduced, but HDL was significantly increased, and the expression of CYP7A1 protein and CYP7A1 mRNA in the liver were significantly increased (all <0.01). The significant difference of each outcome between the EA group and medication group was not observed (all >0.05). CONCLUSION EA could significantly improve blood lipid and promote the expression of CYP7A1 mRNA in rabbits with atherosclerotic, which may be one of the mechanisms of EA for atherosclerosis.
