To explore the changes of retrobulbar hemodynamics in diabetes via color doppler ultrasound.
●METHODS: Totally 80 patients ( 160 eyes ) with eye diseases in type 2 diabetes from June 2010 to May 2013 in our hospital were enrolled as research group. By fundus photography and direct ophthalmoscopy, patients were assigned to diabetes without retinopathy group ( DNR subgroup), non- proliferative diabetic retinopathy group (NPDR subgroup) and proliferative diabetic retinopathy group (PDR subgroup). Of 60 healthy patients (120 eyes) over the same period were chosen as control group. The doppler parameters of central retinal artery ( CRA ), posterior ciliary artery (PCA) and ophthalmic artery (OA) were measured.
●RESULTS: There were significant differences on circulatory parameters of CRA, PCA and OA between both groups ( P < 0. 05 ). Significant differences were also observed on peak systolic velocity ( PSV), end diastolic velocity ( EDV) and resistance index ( Rl) of CRA, PCA and OA among DNR subgroup, NPDR subgroup and PDR subgroup ( P < 0. 05). The EDV, Rl and PSV of control group differed from those of DNR subgroup, NPDR subgroup and PDR subgroup (P<0. 05).
●CONCLUSlON: The monitoring of retinal blood flow and analysis of blood spectrum morphology via color doppler ultrasound can effectively evaluate the degree of diabetic retinopathy lesions, especially before DR vascular disease. Early detection can reveal the hemodynamic change pattern of DR, facilitating the prevention of diabetic eye complications and improvement of the quality of life.

objective To study the relationships between TNF-β gene type in idiopathic dilated cardiomyopathy (IDC). Methods Eighty-six IDC patients were chosen as IDC group and 95 cases unrelated healthy people as control group in the First Hospital of Jilin University in 2008. The levels of TNF-β protein were detected with Enzyme-linked immunosorbent assay(ELISA ). TNF-β polymorphism were analyzed by polymerase chain reaction-restriction fragment length polymorphisms(PSR-RFLP). Results The levels of TNF-β protein in IDC patients[(1.876±1.013) μ/L] were significantly higher than controls[(1.018±0.645)μg/L], the difference being statistically significant (t=2.674,P<0.01). The frequency of TNFβ*2 genotypes in IDC patients[63.4%(109/172] was significantly higher than controls[47.9%(91/190)], the difference being statistically significant(OR=1.88, X2=6.78, P<0.05). Conclusions The TNFβ*2 allele might related to idiopathic dilated cardiomyopathy (IDC), can also be considered as one of susceptible genes of IDC

Objective To study the effect of transcatheter arterial chemoembolizafion (TACE) on inhibitor apoptosis protein-Survivin, Survivin mRNA and proliferating cell nuclear antigen (PCNA). Methods Group A of hepatocelluar carcinoma with preoperative TACE (n = 26), group B of hepatocelluar carcinoma without any interven-tional therapy (n = 30) ,group C of Normal liver (n = 16) were divided. The expression of Survivin mRNA and the expression of Survivin and PCNA were detected. Result ①The positive Survivin mRNA expression in group A and the grey difference were lowere than that in group B (P < 0.05) ; ②The positive Survivin expression and the grey difference in group A were lower than that in group B (P < 0.05) ; ③The proliferating index (PI) of carcinoma tis-sure in group B was higher in group A and group C (P < 0.05 for each). Conclusion There is a high positive ex-pression of Survivin mRNA and Survivin, which may be decreased by TACE and then the proliferation of hepatocellu-lar carcinoma cell is surpressed.

The associating rules have been widely used in traditional Chinese medical (TCM) prescription data mining research work,while Mongolian medical prescription data mining work hardly carried out.In this study,Apriori algorithm based on reduced binary matrix was adopted for the data mining of Mongolian medical prescriptions with the provision of the decision support for research and development of new drugs.Twenty-seven Mongolian medical prescriptions for He Yi disease were involved in the data mining with Apriori algorithm based on reduced binary matrix.It was found that Aquilaria agallocha,Myristica fragrans,Zhen He Yi,or Aquilaria agallocha combined with Myristica fragrans,or Zhen He Yi combined with Myristica fragrans were determined as the Mongolian drugs frequently used in He Yi disease,with 80％ confidence level and 60％ support,and two algorithms were output,[Myristica fragrans--＞Zhen He Yi,0.83] and [Aquilaria agallocha--＞Myristica fragrans,1.00].In conclusion,some potential associating rules and drugs with high frequency in the Mongolian medical prescriptions can be fast mined using Apriori algorithm based on reduced binary matrix,providing a new way for unveiling the medication rules of Mongolian medical prescriptions.

Objective To compare the effect of transthoracic contrast echocardiography (cTTE) with transesophageal contrast echocardiography (cTEE) for detecting right to left shunt (RLS) in patients with patent foramen ovale (PFO). Methods The prospective study was conducted in 29 consecutive patients with PFO who suffered from cryptogenic stroke and/or migraine. Contrast echocardiography was performed in all 29 patients. The cTTE was performed using transducer with second harmonic imaging modality (transmitting frequency 1.7 MHz, receiving frequency 3.4 MHz). The cTEE was performed using transducer with frequency 7 MHz. Ten milliliter saline solution of contrast were rapidly administrated through an antecubital vein. According to whether microbubble (MB) appearing in left atrium after complete opaciifcation of right atrium within the ifrst 3 circles, the results were classiifed by a four-level semi-quantitative categorization:Level 1 (no PFO-RSL), no MB in left atrium; Level 2 (small PFO-RSL) 1-10 MBs; Level 3 (medium PFO-RSL) 10-30 MBs;Level 4 (large PFO-RSL)>30 MBs. Results The total detection rate of PFO-RSL was signiifcant different between cTTE and cTEE (86.2%vs 55.2%,χ2=5.711, P=0.017). In cTTE there were 4 cases at level 1, 1 case at level 2, 5 cases at level 3 and 19 cases at level 4. In cTEE there were 13 cases at leverl 1, 2 cases at level 2, 6 cases at level 3 and 7 cases at level 4. The comparison of semi-quantitative grading derived from cTTE and cTEE was also signiifcant different (Wilcoxon signed ranks test showed Z=-3.789, P=0.000). Conclusions The efifciency in detection of PFO-RLS with cTTE was better than with cTEE. Compared with cTEE, cTTE was easier in practice and brought less discomfort and complications to patients.
