Objective To explore the operative cooperation of the intra-extra cranial bypass operation of the intracranial giant aneurysms. Methods A retrospective analysis of 7 patients who had intracranial giant aneurysm and received the intra-extra cranial bypass operation from October 2014 to June 2016. All preoperative and intraoperative nursing points of operative cooperation were analyzed. Results The post-operative digital subtraction angiographies of 7 patients without any perioperative nursing complications showed enough flow in the bypass arteries. Conclusions Operative multi-incision managing, positive temperature intervening, special instruments using and thrombosis preventing play very important roles in the nursing points of the successful operative cooperation.

Objective To explore the diagnosis,treatment and nursing of the patients complicated with pneumocystis carinii pneumonia (PCP) after renal transplantation,and to enhance the treatment effect of the disease.Methods The treatment and nursing processes of 37 patients complicated with PCP after renal transplantation in department of organ transplantation were retrospectively analyzed in the First Affiliated Hospital of China Medical University from May 1992 to July 2011.And the key points during nursing work were summarized.Results Of the total 37 patients,10 patients occurred respiratory failure,they were all treated by noninvasive ventilation,among which 6 patients were converted to tracheal intubation or tracheotomy mechanical ventilation.5 patients appeared rising serum creatinine(Scr) during treatment,but recovered to normal level after discontinuing SMZco for 1 week.4 patients died unfortunately,and the others were cured and discharged.Conclusions The occurrence of PCP after renal transplantation is closely related to the immune state of the patients,thus the priority of treatment for PCP should be prevention.Once happened,nursing care in aid is particularly important,then nurses should encourage patients to cooperate with treatment,relieve symptoms after infection,and promote recovery as well.

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.

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.

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.

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 ) .
