Objective To investigate the association between brain structure abnormalities and neuropsychology impairment in CAD patients.Methods Nineteen patients with CAD and 1 7 healthy adults were examed with MRI,and T1 WI,T2 WI,FLAIR,DWI and DKI image were performed,and then comparing the acquired MRI findings between two groups.Results Significant differences were observed for MK values in splenium and body of the corpus callosum,left cerebellar hemisphere and amygdala cerebelli.MK values of CAD group were lower than those of healthy group in these regions,and differences were statistically significant(P <0.05). There were significant correlation between MK values of the left amygdala cerebelli and MoCA scores in CAD group.Conclusion DKI could detect the changes of brain tissue microstructure in CAD patients early.The correlation between MK and neuropsychologi-cal function provides an important basis for early diagnosis and treatment.

Objective To analyze the death causes of cadaveric kidney transplantation recipients. Methods The clinical data of 1400 cases of cadaveric kidney tansplantation between 1978 and 2003 were analyzed retrospectivvely. The death rate, causes and period were analyzed among the died recipients after kidney transplantation. Results 187 patients were died after renal transplantation in this stage with the ratio being 13.36% (187/1400). The death causes contained infection, cardiocerebra l vascular diseases and hepatic failure by turns, and the ratio was 37.97% , 31.56% and 14.97% , respectively. There were 87 ( 46.5% ) death cases w ith normal transplanted-kidney function. Conclusions The leading causes of patients' death were infection, cardiocerebral vascular d iseases, and hepatic failure. About half of these patients were died with normal transplanted-kidney function.

In this study, the psbA-trnH sequence was used as DNA barcoding to evaluate the accuracy and stability for identification of Bamboo shavings, Concretio Silicea Bambusae and their closely related species. 56 samples were collected and conducted the DNA extraction. Obtained sequences were assembled using the CodonCode Aligner V4.2, the genetic distances and NJ tree were computed and constructed using MEGA 5.0. The results shows that the maximum intra-specific K2P distances were less than the minimum inter-specific K2P distances. The NJ tree indicated that Bamboo shavings, Concretio Silicea Bambusae and their closely related species can be distinguished from each other clearly, except for Bambusa tuldoides Munro and Bambusa textilis, which perhaps attributed to their closely genetic relationship.

Objective To investigate the risk factors and treatment for infections after spinal internal fixation surgery. Methods The clinical data of 472 patients who underwent spinal internal fixation surgery from January 2012 to December 2012 was analyzed retrospectively, an average age of 50. 6 years (38~78 years). All cases were underwent posterior procedures. All infected patients received emergency opera-tion of wound debridement, drainage and sensitive antibiotic treatment. The mean follow-up time was 11 months (8~19 months). Risk fac-tors and treatment for infections were summarized and discussed. Results Of 472 patients,postoperative infections occurred in 9 cases with the infection rate of 1. 91%. The operation time,intraoperative blood and postoperative drainage was 100~325 min,200~1500 mL and 65~1350 mL,respectively,which were greater than the similar surgeries of same period. The initial signs of wound infection was observed at 10 d (6~16 d) after surgery. CRP,ESR and WBC were significantly increased in 4~7 d after surgery,and maintained at high level at least for 14 d. Bacterial culture results showed infection bacteria were mainly common skin flora. One infection recurred during followed-up and subse-quent treatment was successful. Conclusion Wound infection after internal fixation mainly occurred in the posterior procedure of spine, which were deep infection. The main clinical manifestation was the wound exudate and local deep tenderness,fever and wound surface swelling were relatively rare. Increased intraoperative bleeding,postoperative drainage volume,operation time were the risk factors,which lead to perio-perative malnutrition and subsequent infections. Debridement,drainage,and intravenously sensitive antibiotics could obtain an ideal outcome for most cases. It was not necessary to remove the internal fixation instrument and bone grafting.

Objective To compare the therapeutic effect of inhaled aerosolized and intravenous milrinone,a phosphodiesterase-3 inhibitor in rats with oleic acid-induced acute lung injury (ALI) .Methods Forty male SD rats weighing 300-350 g were randomly divided into 4 groups (n=10 each) : group Ⅰ normal control: group Ⅱ ALI; group Ⅲ milfinone inhalation and group Ⅳ intravenous milrinone.The animals were anesthetized with intraperitoneal 2% pentobarbital 40 mg/kg,tracheostomized and mechanically ventilated (FiO2 30%,VT 10 ml/kg,RR 80 bpm,I:E=1:2).The chest was opened and the heart was exposed.Pulmonary artery was catheterized via fight ventricle.MAP,CVP,airway pressure and pulmonary artery pressure (PAP) were monitored.ALI was induced with 10% oleic acid 2 ml/kg administered through fight external jugular vein in group Ⅱ,Ⅲ and Ⅳ.In control group 0.1% BSA solution 2 ml/kg was administered iv instead of oleic acid.In group Ⅲ at 30 min after oleic acid administration aerosolized milrinone 1 mg/ml was inhaled 4 times at 60 min interval.Each time milrinone was inhaled for 10 min.In group Ⅳ at 30 min after oleic acid administration a bolus of 10 μg/kg milrinone was given iv followed by 10 min milrinone infusion at 1 μ·kg-1·min-1.The same procedure was repeated 4 times at 60 min interval.MAP and PAP were recorded and blood samples were taken from carotid artery and pulmonary artery for blood gas analysis at the 1st,2nd,3rd and 4th treatment.PaO2/FiO2 and Qs/Qt were calculated.The animals were sacrificed by exsanguination after the 4th treatment.The lungs were removed.The left lung was lavaged.Neutrophil count and protein content in broncho-alveolar lavage fluid (BALF) were determined.W/D lung weight ratio and lung myeloperoxidase (MPO) activity were measured.The uhrastructure of the lung was examined with electron microscope.Results The MAP was significantly lower after oleic acid adminstration in group Ⅳ than in other 3 groups.PaO2/FiO2 was significantly decreased and Qs/Qt increased by iv oleic acid in group Ⅱ ,Ⅲ and Ⅳ.PAP was significantly increased after iv oleic acid in group Ⅱ ,Ⅲ and Ⅳ but was significantly lower in group Ⅲ and Ⅳ than in group Ⅱ .The neutrophil count and total protein content in BALF,W/D ratio and lung MPO activity were significantly increased in group Ⅱ ,Ⅲ and Ⅳ as compared with control group(Ⅰ) and were significantly higher in group Ⅳ than in group Ⅲ.The lung damage induced by oleic acid was less serious in group Ⅲ and Ⅳ than in group Ⅱ .Conclusion Inhaled aerosoLized milrinone has better therapeutic effect than intravenous milrinone in rats with oleic acid-induced ALI and is safer.
