Objective To explore the effect of iodine excess on bone metabolism in experimental autoimmune thyroiditis (EAT) rats. Methods We selected 36 female Lewis rats with body weight of (131 ± 15)g,and divided them into 3 groups randomly: control group, EAT group and EAT + high iodine group, assuring 12 rats in every group. These rats were fed fodder with different concentration of iodine(0.9,0.9, 18.0 mg/kg), and rats in EAT group and EAT + high iodine group were immunized with pig thyroglobulin(pTG) and complete Freund's adjuvant(CFA) to create EAT model. After two weeks, the pathological changes of the thyroid tissues were observed,and the serum thyroid autoantibody[thyroglobulin antibody(TGAb) and thyroid microsomal antibody(TMAb)], the thyroid hormone levels[triiodo thyronine(T3) and thyrine(T4)] and some relevant data of bone metabolism[bone gla protein (BGP), tartrate-resistant acid phosphatase (TRAP), C-terminal propeptide of type Ⅰ procollagen (PICP),C-terminal telopeptide of type Ⅰ collagen (ICTP), insulin-like growth factor- 1 ( IGF- 1 ), osteoprotegerin (OPG) and receptor activator of NF-κB ligand (RANKL)] were measured. Results Inflammatory cell infiltration and local follicular structural damage were observed in the thyroid tissues of EAT rats in EAT group and EAT + high iodine group, and the pathological changes of EAT + high iodine group were mainly thyroid follicular expansion and integration. The level of serum TGAb, TMAb, T3 and T4 of EAT rats in EAT group and EAT + high iodine group[ (63.01 ± 12.36)%, (60.62 ± 11.24)%, (3.78 ± 1.43), (125.12 ± 16.00)pmol/L and (75.00 ± 15.44)%,(72.15 ± 15.00)%, (3.69 ± 0.91 ), (149.40 ± 20.67)pmol/L] were higher than those of the control group[ (4.47 ±1.04)%, (5.73 ± 1.01 )%, (0.75 ± 0.12), (76.91 ± 9.30)pmol/L, all P ＜ 0.05], and the level of serum TGAb,TMAb and T4 of EAT rats in EAT + high iodine group were higher than those of the EAT group(all P ＜ 0.05).The level of serum BGP, PICP and IGF- 1 in EAT group[ ( 1.70 ± 0.31 ), ( 11.31 ± 1.52) μg/L, (0.31 ± 0.06 ) mg/L]were lower than those of the control group[ (8.60 ± 0.33), (14.28 ± 3.10)μg/L, (1.16 ± 0.02)mg/L, all P ＜0.05], and the level of serum TRAP, ICTP, OPG and RANKL[ ( 19.88 ± 3.60)ng/L, (2.43 ± 0.82), (22.36 ± 2.80),( 1.35 ± 0.23 )μg/L] were higher than those of the control group[ ( 14.57 ± 3.56)ng/L, (0.50 ± 0.20), (1.61 ± 0.34),(0.10 ± 0.02)μg/L, all P ＜ 0.05]; compared with EAT group, the level of PCIP and OPG in EAT + high iodine group [ (8.03 ± 1.84), ( 16.80 ± 3.79)μg/L] were obviously decreased(all P ＜ 0.05). Conclusions The reinforcement of differentiation and maturation of osteoblast in the EAT rats results in the increasing of bone resorption. The activity of osteoblast and osteoclast of the EAT rats are inhibited by excessive iodine, showing a low conversion-type osteoporosis.

Objective To evaluate the efficacy of L?Arabinose for bowel preparation before colonos?copy. Methods A total of 170 patients who underwent colonoscopy were randomized into 2 groups. The ex?perimental group (n=85) used L?Arabinose for bowel preparation, while the control group (n=85) used polyethylene glycol electrolyte solution ( PEG?ELS ) . The degree of comfort, adverse effects, and the visibility during colonoscopy were observed. Results Premedication of L?Arabinose for bowel preparation yielded to more comfort ( U=-4?349,P=0?000) , less adverse effects (χ2=29?27,P=0?000) , and similar visibility during colonoscopy ( U=-0?875,P=0?381) compared with PEG?ELS. Conclusion L?Arabinose is safe, comfortable, and effective for bowel preparation before colonoscopy.

AIM:Toinvestigatetheeffectofrhynchophylline(Rhy)onbloodpressure,cardiachypertrophy and myocardial fibrosis in spontaneously hypertensive rats ( SHR) .METHODS:Spontaneously hypertensive rats were ran-domly divided into model group , high dose (10 mg? kg-1? d-1 ) and low dose (2.5 mg? kg-1? d-1 ) group of rhyncho-phylline, captopril group (17.5 mg? kg -1? d-1).Wistar-Kyoto rats were used as normal control.Respectively, systolic blood pressure was measured by tail cuff every 2 weeks.After 10 weeks, heart weight index and left ventricular weight in-dex were calculated .The myocardial hydroxyproline and plasma angiotensin Ⅱwere detected .Moreover , basic myocardial histopathological changes and myocardial collagen fibres were observed by HE staining and Masson staining , respectively . The protein expression of TGF-β1 and Smad3 in the myocardium was measured by the methods of immunohistochemistry and Western blot .RESULTS:Compared with SHR model group , Rhy significantly reduced blood pressure ( P<0.05 ) , the levels of HYP in the myocardium (P<0.05) and the levels of AngⅡin the plasma (P<0.01).The pathological dama-ges of the myocardial tissues and collagen deposition were attenuated .The protein expression of TGF-β1 and Smad3 was sig-nificantly reduced by the treatment with Rhy (P<0.01).CONCLUSION:Rhynchophylline reduces blood pressure and adjusts to improve ventricular remodeling of SHR .The mechanism may be involved in the TGF-β1/Smad pathway and re-ducing AngⅡcontent.

BADH-CMO double gene,CMO gene and DREB1A gene were transformed respectively to embryonic callus of Kentucky bluegrass by particle bombardment. Then the embryonic callas of kentucky bluegrass were put in meclium for subculture which is mixed with 100mg/L hygromycin and the meclium for plantlet regeneration which mixell with 50mg/L hy gromycin about one month. Thus,the hygromycin-selectecl plants were obtained and were transplantecl into tlowerpots. The results of the PCR and Southern blot analysis indicated that the DREB1A gene,CMO gene and BADH-CMO double-gene were integrated into the genomic DNA of Kentucky bluegrass.

Embryonic callus of Kentucky bluegrass were used as material for genetic transformation with the DREB1A gene by particle bombardment. Parameters of biolistic bombardment were studied. The optimal methods showed as follows: plasmid DNA are coated by Ca(NO_3)_2 and PEG4000, 1?m golds are the vectors of plasmid DNA, 6 cm bombardment height distance, 1 time and without osmotic treatment are favorable to transgenic efficiency. The concentration hygromycin (Hy) , which is the selection mark for cultivar‘Baron’ is 100mg/L.

Clinical practice is a key step that seven-year clinic student take to become doctors.Take the First Affiliated Hospital of Xi'an Jiaotong University as an example,in the medical practice of seven-year clinic students,there still exist some problems such as students' being unable to transform from probationers to doctors,not good at treating with interpersonal relationship in the department and having no perseverant practice attitude.So training before practice should be perfected and supervision should be strengthened to make the seven-year clinic students better.

Objective To evaluate the effects of a health education and behavior intervention project,and to provide.a scientific basis for brucellosis control.Methods By stratified cluster sampling method,target population from 6 township in Meilisi District were randomly selected to carry out baseline survey.Of these 6 townships 4 were selected as intervention townships,and two as control townships.A health education and behavior intervention program was carried out in intervention townships,and after intervention target population from 6 township were participated in the questionnaire survey.Results Awareness rate of common sense knowledge of farmers in intervention townships was 84.33％ (5237/6210) after intervention which was significantly higher than 53.56％ (2003/3740),before the intervention (x2 =112.49,P ＜ 0.01),and also higher than 54.15 ％ (1787/3300) of the control after the intervention (x2 =101.53,P ＜ 0.01).Average awareness rate(82.13％,2550/3105) of common sense on prevention after intervention was significantly higher than 58.77％(1099/1870) before the intervention (x2 =57.19,P ＜ 0.01).After intervention,average awareness rate of common sense on prevention was significantly higher than that of the average of control townships (70.36％,1161/1650,x2 =25.49,P ＜ 0.01).The awareness rate of treatment before intervention was 36.80％ (116/299),which increased to 76.36％ (436/571)after intervention (x2 =119.38,P ＜ 0.01).After the intervention the awareness rate of intervention townships was significantly higher than that of the controls (33.72％,88/261,x2 =139.69,P ＜ 0.01).In survey of these high-risk behavior in intervention townships,in addition to cattle and sheep which were regularly immunized in the intervention townships(35.91％,121/337),and the control townships(32.01％,97/303,x2 =1.08,P ＞ 0.05) and their difference was not significant,other processing such asapoblema,killing cattle,sheep,cattle to deliver,cutting the wool,regular disinfection,and accuracy of high-risk behavior protection were significantly higher than those of controls[89.83％(106/l18),91.07％(51/56),84.75％(150/177),66.67％(32/48),73.78％(242/328),51.22％(42/82),75.56％(34/45),33.69％(63/187),27.78％(15/54),21.63％(61/282),x2 value were 38.00,5.82,103.84,15.84 and 173.67,all P ＜ 0.05].Conclusion After implementation of health education and behavioral intervention,farmers brucellosis prevention knowledge and awareness of risk behaviors have significantly improved,which have achieved the desired effect.
