The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

Objective To observe the effects of casein and excessive iodine on histomorphalogY and ultrastructure of mouse thymicL Methods Based on 2 × 3 factorial design,the experimental mice were divided into 6 groupg Animal models were estabhshed by feeding the mice with different levels of iodine water and casein food.The levels of iodine were 50,600 μg/L in drinking water and 0(Ⅰ),10%(Ⅱ),20%(Ⅲ)of casein in food respectively.After 12 months,the thyroid weight was measured and the morphology of thyroid was observed under optical and electron microscope.Results Factorial analysis showed that iodine factors obviously affected the thyroid absolute and relative weiights of mice(F=16.23,9.47,P＜0.01),and there was interaction between casein and iodine(F=5.29,4.68,P＜0.01 or＜0.05).Compared wiht 150Ⅰ[(5.91±0.82)rag,(117.0±22.2)mg/kg]and 50Ⅲ[(4.90±0.63)rag,(106.1±13.3)mg/kg]groups.thyroid absolute and relative weights of the mice increased in 600 Ⅰ[(7.60±2.40)mg,(143.3±43.2)mg/kg]and 600Ⅲ[(8.63±1.88)mg,(166.2±39.4)mg/kg]groups(P＜0.05 or＜0.01),respectively.But compared with 600 Ⅰ and 600Ⅲ groups.they were reduced obviously in 600Ⅱ[(5.76±1.13)mg,(109.8±16.5)mg/kg]group(P＜0.05 or＜O.01).Colloid goiter,lymphocyte infiltration were found,some of the follicles epithelial cells appeared active under light and electron microscope in iodine excels group,which,however,decreased obviously along with the increase of casein dose.Conclusions Long-term excessive iodine may cause colloid goiter and inflammation injury of mice,possibly leading the development of thyroiditis in mice,which may be partly reduced by casein.

Objective To discuss the value of diffusion-weighted MRI (DWI) and 18F-FDG-PET/CT in assessing the early therapeutic effect of radiofrequency ablation (RFA) for VX2 sarcomas in experimental rabbits. Methods VX2 sarcoma was inoculated at bilateral hind limbs in 14 New Zealand white rabbits to establish the animal models. The implanted VX2 tumor on one hind leg was treated with ultrasound-guided percutaneous RFA (study group), while no RFA was given to the VX2 tumor on the contralateral hind leg (control group). DWI-MRI was performed at 2 days after RFA, and 18F-FDG-PET/CT examination was employed at 3 days after RFA. The mean apparent diffusion coefficient (ADC) values and standard uptake value (SUV) of the untreated tumor and the ablated tumor were separately calculated. Taking the pathologic result as the gold standard, the consistency of DWI-MRI, PET/CT as well as the combination of DWI-MRI and PET/CT with the clinical diagnosis was separately evaluated by Kappa test. Results Before RFA, DWI-MRI demonstrated that the VX2 tumor was characterized by hypo-intensity signal on T1 and hyper-intensity signal on T2 with ring-shaped enhancement on T1-weighted image; PET/CT showed that the tumor had nodular or ring-shaped 18F-FDG accumulation. After RFA, DWI-MRI revealed that the VX2 tumor was manifested as hyper-intensity signal on T1 and slight higher density on T1 with slight enhancement on contrast-enhanced T1-weighted image; PET/CT showed lowered accumulation of 18F-FDG. The mean ADC value of the ablated tumor was (1.52 ± 0.24) × 10-3 mm2/s, which was obviously higher than that of the un-ablated tumor, that was (1.09 ± 0.12) × 10-3 mm2/s, the difference was statistically significant(P<0.05). The mean SUV value of the ablated tumor was (0.6 ± 0.3), which was significantly lower than that of the ablated tumor (9.6 ± 3.2, P<0.05). No significant difference in sensitivity, specificity and accuracy existed between DWI-MRI and pathology as well as between PET/CT and pathology, the Kappa value being 0.357 and 0.428 respectively (P>0.05). The Kappa value of the consistency between combination of DWI-MRI with PET/CT and pathology was 0.786, which was significantly different from the result by simple DWI-MRI or simple PET/CT evaluation (P< 0.05). Conclusion Both ADC value of DWI-MRI and SUV value of PET/CT are useful indexes for evaluating the early therapeutic effect of RFA. Both DWI-MRI and PET/CT have their respective advantages, nevertheless, combination use of both can effectively improve the evaluation of curative effect for VX2 tumor after RFA in experimental rabbits.

OBJECTIVETo explore the immune mechanism of moxibustion on protecting gastric mucosa injury.

METHODSForty healthy SD rats were randomly divided into four groups: a blank group, a model group, a moxibustion acupoint group and a moxibustion non-acupoint group, 10 rats in each one. Eight days before model establishment, moxibustion at "Zusanli" (ST 36), "Zhongwan" (CV 12), "Guanyuan" (CV 4), "Pishu" (BL 20) and "Weishu" (BL 21) was applied in the moxibustion acupoint group while these acupoints' controlled points were selected in the moxibustion non-acupoint group, and no treatment was given in the model group, once a day in three groups for continuous 16 days. The helicobacter pylori (Hp) model was established by intragastric administration of Hp. HE staining microscopic examination was used to observe inflammation severity in gastric mucosa, and enzyme-linked immunosorbent assay (ELISA) was adapted to measure content of heat shock protein (HSP) 72, TNF-alpha and IL-1beta, and real-time quantitative PCR was used to measure the expression of TLR2 mRNA, TLR4 mRNA, CD14 mRNA and MyD88 mRNA in peripheral blood mononuclear cells, and western blot method was used to measure content of NFkappaB and IkappaBalpha in peripheral blood mononuclear cells.

RESULTSCompared with the blank group, the expression of HP could be seen in the smear of gastric mucosa by Gram's staining in the model group; the inflammation severity score was obviously increased as well as content of serum HSP 72 and TNF-alpha and IL-1beta in gastric tissue; and expression of TLR2, 4 mRNA, CD14 mRNA, MyD88 mRNA, NFkappaB was increased (P < 0.01), but the expression of IkappaBalpha was reduced (P < 0.05). After the moxibustion, the inflammation severity score was reduced in the moxibustion acupoint group, and the content of serum HSP 72 was increased, and the expression of TNF-alpha and IL-1beta in gastric tissue and expression of TLR2 mRNA, TLR4 mRNA, CD14 mRNA, MyD88 mRNA and NFkappaB were reduced (P < 0.01), but the expression of IkappaBalpha was increased (P < 0.05). The differences between the moxibustion non-acupoint group and the model group were not significant (P > 0.05).

CONCLUSIONThe pretreatment of moxibustion at acupoints could induce the over expression of serum HSP 72. By combining TLR 2 and 4 receptors to trigger receptor signal transduction pathways, the releases of downstream signal substances are regulated; as a result, the releases of related immune substances are regulated to relieve the gastric mucosa injury of rats with HP gastritis.

Objective:To observe the effect of moxibustion on the mRNA and protein expressions of heat-shock protein 70 (HSP70) in gastric cancer-bearing rats. Methods: A total of 40 healthy Sprague-Dawley (SD) rats were adaptively fed for one week. The gastric cancer model was prepared by Walker-256 cancer tissue transplantation. After 7 d, 10 rats were randomly selected to verify the successful modeling, and the remaining 30 rats were divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. After enrollment, the moxibustion group received suspended moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36), (the first group of acupoints) on the 1st day, and suspended moxibustion at bilateral Pishu (BL 20) and Weishu (BL 21), (the second group of acupoints) on the 2nd day, 20 min each time, once a day. Moxibustion was alternately performed every other day at the two groups of acupoints for 21 d. From the day of enrollment, rats in the infrared group were irradiated with the infrared radiation at the stomach area on the 1st day, and at the T12-T13 interspinous region on the 2nd day, 20 min each time, once a day, and the two locations were alternately irradiated every other day for 21 d. During the treatment, rats in the model group were intervened by grasping and fixation without treatment. At the end of the treatment, blood was collected from the inner eye orbit, and the HSP70 expression in peripheral blood was determined by enzyme linked immunosorbent assay (ELISA). Rats were sacrificed, the tumor volume and growth inhibition rate were measured. The position and changes of HSP70 in gastric cancer were observed by streptavidin-perosidase (SP); HSP70 protein expression was determined by ELISA; HSP70 mRNA expression in cancer tissues was determined by reverse transcription-polymerase chain reaction (RT-PCR) assay. Results: In comparison of the model group, the volume growth of the gastric cancer in the moxibustion group was significantly restricted (P＜0.01); the volume growth inhibition rate in the moxibustion group was 37.93%; the HSP70 expression in peripheral blood and the cancer tissues was significantly increased (both P＜0.01); the expression of HSP70 mRNA and HSP70 content in gastric tumor were both obviously increased in the moxibustion group (P＜0.01); and a large amount of HSP70 was released to the outside of cancer cells in the moxibustion group. In comparison of the model group, the volume growth of the gastric cancer in the infrared group was slightly restricted (P＜0.05) with a volume growth inhibition rate of 15.89%; the HSP70 expression in the infrared group was increased significantly in peripheral blood (P＜0.01) and in the gastric cancer tissues (P＜0.05); more HSP70 was released outside of the cancer cells in the infrared group. In comparison of the infrared group, the volume growth of gastric cancer was more restricted in the moxibustion group (P＜0.05), and the HSP70 expression in the gastric cancer tissues was also higher (P＜0.05); more HSP70 was released outside of the cancer cells in the moxibustion group. Conclusion: Moxibustion and infrared treatment inhibit the gastric cancer growth in the gastric cancer-bearing rats, up-regulate the HSP70 expression in gastric cancer tissues, and promote the production and extracellular release of HSP70, and the effect of moxibustion is more obvious.

OBJECTIVETo explore the mechanism of cake-separated moxibustion in treatment of hyperlipemia.

METHODSSixty rabbits were randomly divided into 4 groups, a blank group,a model group, a direct moxibustion group and a cake-separated moxibustion group. Hyperlipemia model was developed by high fat diet of cholesterol. Changes of ultrastructures of endothelial cells of the aorta of the rabbit were observed with electron microscope.

RESULTSThe endothelial cells in the cake-separated moxibustion group were more intact, most of them were normal in forms, internal elastic membrane was continuous, their thickness was even, the cells of smooth muscles in the medial membrane were relatively normal, which are similar to those in the blank control group. But the structure of endothelial cells of the aorta in the model group disappeared, in cytoplasm the sedimentation of a great number of lipids can be seen, internal elastic membrane was interrupted, the thickness was uneven, with focal dissolution, the cells of smooth muscle in the medial membrane had sedimentation of lipids, with frothy change.

CONCLUSIONCake-separated moxibustion has a certain protective action on endothelial cells of the aorta in the rabbit of hyperlipemia.

OBJECTIVETo detect the "high pathogenicity island" of Yersinia enterocolitica WA in E. coli and the to provide evidence for theory base of bacterial evolution process and the different structures in different E. coil.

METHODSPolymerase chain reaction (PCR), nucleic acid hybridization in situ were used to detect and identify HPI. DNA sequencing was used to compare the gene homology of HPI among E. coli with Yersinia enterocolitica (Yen).

RESULTSThe irp2 and fyua genes of Yen HPI were investigated in E. coli strains. Among them, 30 strains were isolated from 93 Enterotoxigenic E. coli (ETEC) strains and 3 strains were positive in 10 strains Enteropathogenic (EPEC). HPI was also detected in Enteroaggregative E. coli (EAggEC) strain. In most of these isolates, HPI was bordered by an asntRNA locus, as in Yersinia sp. Through sequential comparison, the gene sequence homology was higher between in EPEC and EAggEC than ETEC and Yersinia enterocolica.

CONCLUSIONSETEC, EPEC and EAggEC were pathogenicity bacterias and many of them harboring HPI of Yen and the HPI had the same position in E. coli chromosome as Yersinia enterocolitica but the diversity of structure and sequence in these E. coli might suggest that the HPI of these different serotype E. coli were from different ancient bacterias. At the same time, the high positivity rate of HPI in E. coli might be crucial to virulence change, virulence evolution and virulence regulation in E. coli.

Objective Take alkaline ashing method as golden standard to explore the accuracy of chloric acid digestion method in determination of human milk iodine. Methods Sixty one breast milk samples collected in Hexi district of Tianjin was measured by the method for determination of iodine in foodstuff by As3+-Ce4+ catalytic spectrophotometry (referred to as the alkaline ashing method) published in 2008 and the method for determination of iodine in urine by As3+-Ce4+ catalytic spectrophotometry(referred to as acid digestion) published in 1999, respectively. were highly correlated(r = 0.960, t = 26.3, P < 0.01), and the regression equation was (Y) = - 28.1 + 0.808X, in which X was independent variable, that is the results of alkaline ashing method; (Y) was dependent variable, that is the estimated data of chloric acid digestion method. The average difference of the results measured by the two methods was 68.3 μg/L, and the results from chloric acid digestion was 38.9% which lower than that of alkaline samples were diluted by 3,4 and 5-fold and then digested by chloric acid, the liquid clarification rates were 80.3% ashing and chloric acid digestion method were, respectively, 165.4, 110.0 μg/L. Conclusions Compared with alkaline ashing method, the results determined by chloric acid digestion method are significantly lower. It is suggested that there are systemic errors in chloric acid digestion method, which means that alkaline ashing method can not be replaced by the chloric acid digestion method.
