OBJECTIVETo observe the effect of cold or hot properties of traditional Chinese medicines (TCM) on biological effect indexes, and analyze the contribution of variables on cold or hot properties, in order to preliminarily establish the discrimination mode for the biological effects of cold or hot properties.

METHODRats were randomly divided into the blank control group, cold TCM groups (Coptidis Rhizoma, Scutellariae Radix, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix and Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex and Evodiae Fructus), and orally administered with 10 mL x kg(-1) of corresponding TCM water decoctions for 30 d, twice a day. Altogether 53 biological effect indexes correlated to cold or hot properties of traditional Chinese medicines were founded by searching literatures. The data warehouse were established by using data-mining software Clementine12.0. Data of the blank control group, cold TCM groups (Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix, Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex) were selected into a training set. C5.0 algorithm and C&R classification and regression algorithm were adopted to define the importance of variable, create the decision trees, and test hot or cold properties of Evodiae Fructus and Scutellariae Radix.

RESULTAccording to C&R classification and regression algorithm, SDH activity of livers was the most important hot or cold property, with the significance closed to 30%. It was followed by triglyceride, liver Na' -K' -ATPase enzyme, muscle glycogen and platelet distribution width, with the accuracy up to 97.39% in models. C5.0 algorithm showed that liver SDH activity was the most important hot or cold property, with the significance closed to 40%. It was followed by triglyceride, GOT, muscle glycogen and liver Na(+)-K(+)-ATPase enzyme, with the accuracy up to 98.26% in models. The possibilities that Evodiae Fructus is in hot property and Scutellariae Radix is in cold property were 100. 00% and 77.78% by using both C&R classification and regression algorithm and C5.0 algorithm.

CONCLUSIONThe SDH activity of liver is the most important biological effect index to distinguish cold and hot properties of TCMs. The discrimination pathway or mode of cold and hot properties is closely related to energy metabolism.

Objective To explore the possible factors associated with twice human brucellosis epidemics in Inner Mongolia during 1952 to 2007 to provide scientific tactics for prevention and control brucellosis. Methods Surveillance data and literature about human brucellosis during 1952 to 2007 in Inner Mongolia was collected, descriptive analysis of human brucellosis incidence on distribution in the regions and among occupations was carried out during 1952 to 2007. Results In Inner Mongolia, the first epidemic of human brucellosis peak appeared in the early 1960s, spreading to 12 regions, at an incidence of 55.28/100 000 in 1961, 72.9% of the Brucella infected people were herdsman;another epidemic peak seriously hit middle and eastern regions after 2000, the incidence being 38.44/100 000 in 2005;51.9% and 28.7% of the new brucellosis cases were respectively peasant and herdsman. Conclusions In Inner Mongolia, animal husbandry industry has been rapid developed since the early 1990's, resulting frequent livestock trade without quarantine, at the same time the public health system doesn't match the development, so the epidemic situation of brucellosisbecomes more and more serious after mid-90's, and has reached the peak during 2004 and 2007.

Objective To investigate the epidemiological characteristics of human brucellosis in Ulanqab of Inner Mongolia.Methods Three hundred and twenty patients with suspected brucellosis were selected,who had registered in the Ulanqab Center for Endemic Disease Control of Inner Mongolia from April to June 2011.The investigation covered general situation,such as gender,age,occupation and main clinical symptoms and so on.Blood samples were collected,and Rose Bengal plate agglutination test(RBPT) was used for serum screening.Those who were tested positive in RBPT were confirmed with tube agglutination test (SAT).Brucellosis was diagnosed according to Diagnostic criteria for Brucellosis (WS 269-2007).Data were analyzed with statistical software(SPSS 17.0).Results One hundred and thirty-four cases were positive in RBPT of the 320 people surveyed,of which 93 cases were positive in SAT; antibody titers were higher than 1 ∶ 100(++),therefore they were diagnosed as brucellosis,and the ratio was 29.1％(93/320).The number of patients with suspected brucellosis who were negative in SAT test was 41,and the ratio was 12.8％ (41/320).Among the 93 people who were infected,the constituent ratio of farmers and herdsmen who engaged in livestock was the highest,accounted for 63.4％(59/93) and 24.7％ (23/93) of the total number of patients ; infection rate of male (30.9％,55/178) was higher than that of females (26.7％,38/142) ; the number(39) of brucellosis patients who were over the age of 51 was the highest,and the ratio is 42.0％.The onset season mainly in May and August; main route of exposure was bare hands lambing,midwifery and contact with infected sheep pollutants.Conclusions Sheep is the main source of human Brucella infection in Ulanqab.It is the key to control the spreading of brucellosis through improving awareness of disease prevention among farmers and herdsmen as well intensifying the prevention and control of Brucella infection between livestock.

ObjectiveTo study tumor necrosis factor-related apoptosis-inducing ligand(TRAIL) 1525 locus polymorphism in patients with nodular thyroid disease and investigate the relation between individual gene polymorphism and thyroid diseases.Methods A total of 125 patients were diagnosed with nodular thyroid disease at the Department of Endocrinology,the First Affiliated Hospital of Inner Mongolia Medical College.Among these patients,67 cases were nodular thyroid goiter and 58 cases were nodular thyroid adenoma,54 males,71 females,and average age was 41.05 ± 14.42. Patients with nodular thyroid goiter were grouped into toxic and non-toxic and thyroid adenoma were grouped into high-functioning or non-high-functioning.A total of 100 healthy subjects.47 males,53 females,average age 42.35 ± 16.52 were as control group.According to the principle of informed consent,venous blood was collected,polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for TRAIL gene 1525 locus polymorphism determination was performed to calculate genotype of the TRAIL gene (homozygous GG,heterozygous GA,mutationhomozygous AA) and the gene frequency (G,A),and relative degree of risk(odd ratio,OR) was compared.ResultsNodular goiter group TRAIL gene 1525 locus genotype frequencies(GG:40.3％,AG:44.8％,AA:14.9％),allele frequencies(G:62.7％,A:37.3％) were compared with that of the control group(GG:17.0％,AG:65.0％,AA:18.0％; G:49.5％,A:50.5％),the differences were statistically significant(x2 =11.376,5.633,P ＜ 0.01 or ＜ 0.05 ).Adenomas group 1525 locus genotype frequencies of the TRAIL gene(GG:44.8％,AG:38.0％,AA:17.2％),allele frequencies(G:63.8％,A:36.2％) were compared with that of the control group,the differences were statistically significant(x2 =15.342,6.054,P ＜ 0.01 or ＜ 0.05).Allele frequencies of thyroid goiter group and denoma group were compared with that of the control group,OR values were 1.714 and 1.797(all P ＜ 0.05) and 95％ confidence intervals were 1.097 - 2.679 and 1.124 - 2.874.The difference of 1525 locus genotype or allele frequency distribution in toxic and non-toxic nodular group,high functioning and non-high-functioning adenomas group were not statistically significant (x2 =3.714,2.792; 1.103,2.020; all P ＞ 0.05).ConclusionTRAIL gene 1525 locus polymorphism is significantly associated with nodular thyroid disease.

Medium-chain fatty acids (MCFAs) are mostly generated from dietary triglycerides and can penetrate the blood-brain barrier. Astrocytes in the brain use MCFAs as an alternative energy source. In addition, MCFAs have various regulatory and signaling functions in astrocytes. However, it is unclear how astrocytes sense and take up MCFAs. This study demonstrates that decanoic acid (DA; C10), a saturated MCFA and a ligand of G(αs) protein-coupled receptors (G(αs)-GPCRs), is a signaling molecule in energy metabolism in primary astrocytes. cAMP synthesis and lactate release were increased via a putative G(αs)-GPCR and transmembrane adenylyl cyclase upon short-term treatment with DA. By contrast, monoamine oxidase B-dependent gamma-aminobutyric acid (GABA) synthesis was increased in primary cortical and hypothalamic astrocytes upon long-term treatment with DA. Thus, astrocytes respond to DA by synthesizing cAMP and releasing lactate upon short-term treatment, and by synthesizing and releasing GABA upon long-term treatment, similar to reactive astrocytes. Our data suggest that astrocytes in the brain play crucial roles in lipid-sensing via GPCRs and modulate neuronal metabolism or activity by releasing lactate via astrocyte-neuron lactate shuttle or GABA to influence neighboring neurons.

OBJECTIVES: Magnetic resonance imaging (MRI)-guided high intensity focused ultrasound surgery (MRgFUS) is a newly emerging non-invasive technique for the treatment of uterine fibroids. The purpose of this study is to review the clinical impact of MRgFUS. METHODS: This study examined 157 patients. The high intensity focused ultrasound (HIFU) utilized in this study was Philips Achieva 1.5 Tesla MR (Philips Healthcare, Best, the Netherlands) and Sonalleve HIFU system. The patients were followed in post-operative Month 1, Month 3, and Month 6 to investigate any change. Then, these were further classified according to the use of uterine stimulant (oxytocin) in parallel, Funaki Type of uterine fibroid, HIFU intensity, and non-perfused volume (NPV) ratio. RESULTS: When the uterine stimulant was utilized, the HIFU intensity was measured at significantly lower levels, compared with the group not using uterine stimulant, and treatment duration was significantly. The NPV ratio was found significantly higher in the group using uterine stimulant. Concerning the correlation between Funaki Type of uterine fibroid and average sonication power, it was found that the closer to Type I, the lower the sonication power, the shorter the treatment duration, and the higher the NPV ratio significantly. CONCLUSIONS: In this study, it was found that the lower the Funaki Types of uterine fibroids, and the higher the NPV ratio immediately after the operation, the larger the uterine fibroid volume decrease and SSS change were. Also, if uterine stimulant was used in parallel in treatment, treatment duration and HIFU intensity could become shorter and lower.

This paper is to establish a reversed-phase ion-pair chromatography (RP-IPC) method for universal estimation of the octanol/water partition coefficients (logP) of a wide range of structurally diverse compounds including acidic, basic, neutral and amphoteric species. The retention factors corresponding to 100% water (logk(w)) were derived from the linear part of the logk'/phi relationship, using at least four isocratic logk' values containing different organic compositions. The logk(w) parameters obtained were close to the corresponding logP values obtained with the standard "shake flask" methods. The mean deviation for test drugs is 0.31. RP-IPC with trifluoroacetic acid as non classic ion-pair agents can be applicable to determine the logP values for a variety of drug-like molecules with increased accuracy.

OBJECTIVETo study the protected effect of Yindan Xinnaotong capsule (YDXNTC) and main components compatibility on myocardium ischemia/reperfusion injury.

METHODGlobal ischemia/reperfusion was adopted to induce myocardial ischemia/reperfusion injury (MIRI) in isolated rat heart. Sprague-Dawley (SD) rats were divided into control, model, YDXNTC, Ginkgo biloba extract (GBE) group, ethanol extract of Salvia miltiorrhiza (SM-E) group, aqueous extract of Salvia miltiorrhiza (SM-H) group, mixed compatibility of other components in YDXNTC (MC), GBE and SM-E compatibility (GSEC), GBE and SM-H compatibility (GSHC), and SM-E and SM-H compatibility (SEHC). During the experiment, electrocardiogram was recorded to observe cardiac arrest time, heart resuscitation time, regaining normal rhythm time, the incidence and duration of arrhythmias (VT/VF). At the end of reperfusion, hearts were arrested and homogenated to assay the activity of superoxide dismutase (SOD), and the content of malondialdehyde (MDA), lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), cardiac troponin I.

RESULT(1) YDXNTC, SM-E, SM-H and MC elevated cardiac arrest time, also reduced rebeating time, restoring normal rhythm time as well as the duration of arrhythmia, but no remarkable impact on VT/VF occurrence. GBE was effective for incidence of VT/VF, also achieved good effect on shortening rebeating time, restoring normal rhythm time and arrhythmia duration. Likewise, obviously reduced rebeating time, restoring normal rhythm time and arrhythmia duration, and evaluated cardiac arrest time were also exhibited in compatibility groups except that no lengthened cardiac arrest time was detected in GSHC. And the incidence of VT/VF was decreased by GSEC. (2) YDXNT, ginkgo biloba extract (GBE), ethanol extract of salvia miltiorrhiza (SM-E), GBE and SM-E compatibility (GSEC), and SM-E and aqueous extract of salvia miltiorrhiza (SM-H) compatibility (SEHC) could improved SOD and decreased MDA level SM-H, mixed compatibility of other elements in YDXNTC (MC) and GBE and SM-H compatibility (GSHC) showed a role on MDA reduction. (3) LDH was declined by YDXNT and SM-H. CK-MB was reduced by GBE, SM-E, SM-H, and GSEC. (4) The release of cTnI was only inhibited by GSEC.

CONCLUSIONYDXNTC, primary materials and main components compatibility has a certain protection effect on MIRI, its mechanism may be related to antioxidant and calcium overload reduction.
