OBJECTIVETo observe effects of mild moxibustion and lovastatin on immunologic function in rabbits with chronic hyperlipidaemia and atherosclerosis (AS) to initially explain regulating rules of mild moxibustion on immunologic function.

METHODSAmong thirty-two Japanese male big-ear rabbits, 8 rabbits were randomly selec ted as a blank group, the rest 24 rabbits were fed with method of endothelial injury and high-fat diet to establish AS model. The blank group was raised with normal diet and free water. After ten weeks of model establishment, the rest 24 rabbits were randomly divided into a model group, a moxibustion group and a medicine group, eight rabbits in each one. Moxibustion was applied at "Shenque" (CV 8) and "Zusanli" (ST 36) for 10 min per acupoint per day in the moxibustion group, while intragastric administration of 3.6 mg/kg lovastatin capsule was applied in the medicine group. After treatment, serum was acquired. Spectrophotometry method was adapted to measure cholesterol (TC) and high-density lipoprotein (HDL-C) and evaluated atherosclerosis index (AI), while enzyme-linked immunosorbent assay method was used to measure interferon-gamma (IFN-gamma) and interleukin-4 (IL-4).

RESULTS(1) The serum TC and HDL-C in the model group were significantly higher than those in the blank group, moxibustion group and medicine group (all P < 0.01). The mean value of AI was 1.683 +/- 0.486 in the moxibustion group, which was obviously lower than 20.301 +/- 4.022 in the model group (P < 0.01). (2) The ratio of Th1/Th2 was 0.569 +/- 0.143 in the moxibustion group and 0.445 +/- 0.079 in the medicine group, which were significantly lower than 0.917 +/- 0.255 in the model group (both P < 0.01), but there was no statistically significant difference between the moxibustion group and the medicine group (P > 0.05).

CONCLUSIONThe moxibustion for AS could reduce atherosclerosis index, influence drift and bias of helper T cell and regulate balance between humoral immunity and cellular immunity. As a result, status of relative balance of immunity is acquired, which could slow down the development of atherosclerosis and process of thrombus burst.

Objective:To investigate the risk factors and predictive effect of lateral cervical lymph node metastasis of papillary thyroid carcinoma (PTC) by applying the concept of central lymph node metastasis intensity.Methods:This study retrospectively analyzed integrated clinic data of 106 cases with PTC undergoing treatment of cervical lymph node dissection in Department of Thyroid and Breast Surgery of the Affiliated Hospital of Inner Mongolia Medical University from Dec. 2009 to Jan. 2014. Based on whether lateral cervical lymph nodes had metastasis, patents were classified into lymph node metastasis positive group ( n=75 cases) , lymph node metastasis negative group ( n=31 cases) . This study explored metastasis-associated risk factors of age, gender, triiodothyronine (T3) , thyroxine (T4) , free triiodothyronine (FT3) , free thyroxine (FT4) , thyroid stimulating hormone (TSH) , thyroglobulin antibody (TGAb) , thyroid peroxidase antibody (TPOAb) , whether combined with Hashimoto’s disease, tumor location, infringing the membrane, mulifocality, tumor glands distribution, tumor diameter, number of central lymph node metastases, central lymph node metastasis ratio, and analyzed the effects of central lymph node metastasis intensity on lateral cervical lymph node metastasis. SPSS 21.0 software was used for data analysis, the metering data of normal distribution was expressed as ± s, and t test was used for comparison between groups. Count data was expressed as a rate (composition ratio) , and comparisons between groups were performed by χ2 test or Fisher exact probability method. Results:Univariate analysis found that whether combined with Hashimoto’s disease ( P=0.087) , tumor location ( P=0.249) , tumor glands distribution ( P=0.219) and tumor diameter ( P=0.224) had no correlation with lateral cervical lymph node metastasis, which showed no statistical significant differences ( P>0.05) . Infringing the membrane ( P=0.030) , mulifocality ( P=0.031) , number of central lymph node metastases ( P=0.022) and central lymph node metastasis ratio ( P=0.001) had correlation with lateral cervical lymph node metastasis, which showed statistical significant differences ( P<0.05) . The number of central lymph node metastases and the increase of central lymph node metastasis ratio had positive correlation with the occurrence of lateral cervical lymph node metastasis; when the number of central lymph node metastases was ≥4 or (and) the central lymph node metastasis ratio was ≥20%, the incidence of lateral cervical lymph node metastases increased significantly, and the difference was statistically significant ( P<0.05) . Conclusion:Infringing the membrane and mulifocality are risk factors for lateral cervical lymph node metastasis. When central lymph node metastasis intensity: number of metastases ≥4 or (and) metastasis ratio ≥20%, lateral cervical lymph node dissection is recommended.

A method was established for the simultaneous determination of the total fatty acid esters of chloropropanols in edible oils by gas chromatography-mass spectrometry combined with isotope dilution technology. The samples were hydrolyzed with sodium methylate-methanol, and then purified by diatomite cartridge. After being derivatized with heptafluorobutyrylimidazole ( HFBI ), the target analytes were determined by GC-MS with the deuteriumchloropropanols esters as the internal standards. An excellent linear correlation in the range of 0. 050-2. 000 mg / L was acquired for 3-monochloropropane-1,2-diol (3-MCPD) esters, 2-MCPD esters, dichloropropan-2-ol (1,3-DCP) esters and 2,3-dichloropropan-1-ol (2,3-DCP) esters, with all the correlation coefficients (r) higher than 0. 9995. The limits of detection (LODs) for 3-MCPD esters, 2-MCPD esters, 1,3-DCP esters and 2,3-DCP esters were 0. 015, 0. 015, 0. 030, and 0. 030 mg / kg, respectively, and the limits of quantitation (LOQ) were 0. 050, 0. 050, 0. 100, and 0. 100 mg / kg, respectively. The average spike recoveries of the four kinds of chloropropanols esters in blank extra virgin olive oil matrix were typically in a range of 87. 0% -110. 5% with the relative standard deviations (RSDs) less than 10. 1% . The detection rates of 3-MCPD esters, 2-MCPD esters, 1,3-DCP esters and 2,3-DCP esters in 74 edible oil samples were 94. 6% , 63. 5% , 5. 4% , and 0% , respectively. The contamination levels of 3-MCPD esters, 2-MCPD esters and 1,3-DCP esters were in the range of not detected (ND) to 10. 646 mg / kg, ND to 3. 617 mg / kg and ND to 0. 089 mg / kg, respectively. This method is accurate and rugged for the simultaneous determination of total fatty acid esters of chloropropanols in edible vegetable oils.

Some unhealthy life habits, such as long-term smoking, heavy drinking, sexual overstrain and frequent stay-up could induce the Yin deficiency symptoms of zygomatic red and dysphoria. Stems of Dendrobii officinalis flos (DOF) showed the efficacy of nourishing Yin. In this study, the hyperthyroidism Yin deficiency model was set up to study the yin nourishing effect and action mechanism of DOF, in order to provide the pharmacological basis for developing DOF resources and decreasing resource wastes. ICR mice were divided into five groups: the normal control group, the model control group, the positive control group and DOF extract groups (6.4 g · kg(-1)). Except for the normal group, the other groups were administrated with thyroxine for 30 d to set up the hyperthyroidism yin deficiency model. At the same time, the other groups were administrated with the corresponding drugs for 30 d. After administration for 4 weeks, the signs (facial temperature, pain domain, heart rate and autonomic activity) in mice were measured, and the facial and ear micro-circulation blood flow were detected by laser Doppler technology. After the last administration, all mice were fasted for 12 hours, blood were collected from their orbits, and serum were separated to detect AST, ALT, TG and TP by the automatic biochemistry analyzer and test T3, T4 and TSH levels by ELISA. (1) Compared with the normal control group, the model control group showed significant increases in facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01), serum AST, ALT (P < 0.01), T3 level (P < 0.05), TSH level (P < 0.05) and notable deceases in pain domain (P < 0.01), TG level (P < 0.01). (2) Compared with the model control group, extracts from DOF (6 g · kg(-1)) could notably reduce facial and ear micro-circulation blood flow, facial temperature and heart rate (P < 0.05, P < 0.01) and AST (P < 0.05) and enhance pain domain (P < 0.01) and TG (P < 0.01). Extracts from DOF (4 g · kg(-1)) could remarkably reduce AST and ALT levels (P < 0.01, 0.05). Extracts from DOF (6 g · kg(-1) 4 g · kg(-1)) could significantly reduce T3 and increase serum TSH level (P < 0.05). DOF could improve Yin deficiency symptoms of zygomatic red and dysphoria in mice as well as liver function injury caused by overactive thyroid axis. According to its action mechanism, DOF may show yin nourishing and hepatic protective effects by impacting thyroxin substance metabolism, improving micro-circulation and reducing heart rate.

Objective To investigate the imaging characteristics of different biliary strictures after liver transplantation and their relationship with causes. Methods Forty-six patients with jaundice and biliary stricture were enrolled in this study.The diagnosis was confirmed by percutaneous transhepatic cholangiography (PTC).All the patients had hepatic arteriography with DSA or CTA and underwent liver biopsy.Their imaging characteristics were analyzed and the related statistic analysis was conducted.Results Anastomosis biliary stricture (ABS) was demonstrated in 21 cases,and non-anastomosis biliary stricture (NBS) with hepatic artery thrombosis (HAT) occurred in 13 cases,and there were 12 cases of NBS without HAT.PTC examination confirmed there were 26 cases of biliary stricture at hepatic hilum,and the incidence of biliary stricture in NBS group was significantly higher than that in ABS group (92％ vs.14.35％,P＜0.05).There were 31 cases of intrahepatic bile duct stricture,and the incidence in NBS group was significantly higher than that in ABS group ( 100％ vs.28.6％,P＜0.05).There were 33 cases of dilatation of intrahepatic bile duct,and the incidence in NBS without HAT group was significantly lower than that in ABS group and NBS with HAT group (16.7％,100％ and 76.9％ respectively) (P＜0.05).There were 21 cases of extrahepatic biliary dilatation,and the incidence in ABS group was significantly higher than that in NBS group (85.7％ vs. 12％,P＜0.05). There were 18 cases of stricture and dilatation in intrahepatic bile duct,and the incidence in NBS with HAT group was significantly higher than that in ABS group and NBS without HAT group (76.9％,28.6％ and 16.7％ respectively,P＜0.05).The results of the liver biopsy were accorded with the diagnosis of biliary stricture,Conclusion The different biliary strictures carry different imaging characteristics,including location of biliary stricture,and location and type of secondary biliary dilatation.

OBJECTIVETo explore effects and action mechanism of warm moxibustion on regulation of blood lipids and anti-atherosclerosis.

METHODSForty-one male Japanese big-ear white rabbits were randomly divided into a blank group (10 rabbits), a model group (10 rabbits), a moxibustion group (10 rabbits) and a medication group (11 rabbits). Normal diet was applied in the blank group while high-cholesterol diet combined with injection of bovine serum albumin were applied in the rest groups to establish rabbit model of atherosclerosis. After establishment, the model group was not intervened and warm moxibustion was applied in the moxibustion group at "Zusan-li" (ST 36) and "Shenque" (CV 8), 10 min per acupoint per day for continuous 4 weeks. The medication group was treated with intragastric administration of lovastatin capsule (3.6 mg/kg) for continuous 4 weeks. The level of blood lipids, such as total cholesterol (TC), triglyceride (TG), and content of CD40 ligand (CD40L), soluble CD40 ligand (sCD40L) and expression of nuclear factor NF-kappaB were tested after 4 weeks.

RESULTSCompared with the model group, the moxibustion group and medication group could effectively reduce the contents of TC and low density lipoprotein (all P < 0.05), lower the level of sCD40L [(8.310 +/- 1.221) ng/mL in the model group, (7.097 +/- 0.846) ng/mL in the moxibustion group and (7.354 +/- 0.631) ng/mL in the medication group], reduce expression of CD40L [(0.235 +/- 0.179) mm2 in the model group, (0.072 +/- 0.079) mm2 in the moxibustion group and (0.039 +/- 0.015) mm2 in the medication group] and NF-kappaB [(0.145 +/- 0.052)mm2 in the model group, (0.052 +/- 0.012) mm2 in the moxibustion group and (0.036 +/- 0.013) mm2 in the medication group], indicating the significant difference (P < 0.05, P < 0.001). There was no statistical difference between the moxibustion group and medication group (all P > 0.05).

CONCLUSIONThe warm moxibustion has great effect on regulation of blood lipids and anti-atherosclerosis, in which lowering expression of CD40-CD40L could be one of possible mechanisms to take effect of anti-atherosclerosis.
