Objective To evaluate short-term curative effect of endovascular abdominal aortic aneurysm repair. Methods Twelve cases of infra-renal abdominal aortic aneurysms were checked. Results The av-erage bleeding in the operation was 245 millimeter, the avenage hospitalization time was 8.6 days, and the average abrosia time was 1.5 days. White blood cell, hemoglobin, thrombocyte, hepatic function, and renal function were in the normal limits. Prothrombin time and activated partial thromboplastin time were post-poned after operation, and recovered normally within one week. Complications of operations were as follows:1 case of pulmonary infection, 2 cases of abdominal distention, and 1 case of intraoperafive endoleak. The former two kinds of complications alleviated after conventional treatment, and the latter disappeared naturally after 3 months. Conclusion Endovascular abdominal aortic aneurysm repair is safe, mini-invasive, and has little disturbance for body internal environment.

In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out. The results of fingerprint analysis, correlation analysis, principal component analysis and cluster analysis can identify the geographic origins correctly, which verified and supplemented each other; the identification results and the actual location showed a high degree of consistency, namely the lower the space distance, the greater the similarity of different samples. These results revealed the obvious superiority and practical value in comparison to the more tedious and time-consuming wet chemistry method normally used. Using appropriate metrology methods can trace the geographical source correctly. The M. tenacissima materials from the region of Maguan should be considered as genuine medicinal materials taking into account the good quality.

OBJECTSTo investigate the distribution of vitamin D receptor (VDR) genotypes among the Hans of a lead contaminated mine in Shanxi and explore the relationship between blood lead levels and the genetic polymorphism of VDR gene.

METHODSVDR genotypes were determined by polymerase-chain-reaction and restrictive fragment length polymorphism (PCR-RFLP) and the blood lead level was measured by using the graphite furnace atomic absorption spectrometry in a population of 120 pre-school children aged 5 - 6 years who were from the mine kindergarten and were unrelated Hans. An environmental questionnaire in relation to blood lead level was filled for each subject.

RESULTS(1) The gene distribution of the VDR phenotypes in these children was VDRBB, 1.7%; VDRBb, 9.2%; VDRbb, 89.2%. (2) The mean blood lead level of the children who had VDR B allele [(0.910 8 +/- 0.265 0) micromol/L] was significantly higher than that whose VDR genotype was bb [(0.740 1 +/- 0.270 1) micromol/L (mean +/- standard deviation)] (t = 2.155, P < 0.05). (3) Many factors were found to affect the blood lead levels, such as the VDR genotype, the type of fuel, educational level of mothers and so on. After controlling the possible confounding variables by multiple regression, the contribution of the VDR phenotype to the blood lead levels was still statistically significant.

CONCLUSIONThese results indicated that the frequency distribution of the VDR genotype in these children was apparently different from that in Caucasians who had high frequencies of VDR B. The results also indicated that the individuals carrying the VDR B allele were more susceptible to lead poisoning.

Objective To evaluate the risk factors of patients with acute kidney injury (AKI) in patients with chronic kidney disease (CKD) for the early detection and early treatment of CKD.Methods One hundred and twenty-seven CKD patients were divided into groups according to AKI existing, 60 cases with out AKI (CKD group), 67 cases with AKI (A/C group) and then A/C group patients were divided into non-older age group (35 cases, ＜60 years old) and older age group (32 cases, ≥60 years old).The protopathy, causative factors and so on were analyzed.Results There was different causative factors in different age group.Logistic regression model indicated that the major risk flactors of AKI in CKD were severe infection (OR = 5.236),hypovolemia (OR = 5.083 ),heart failure (OR = 8.283) and using renal toxicity medicine (OR = 5.246),P ＜ 0.05.Conclusion The major risk factors of AKI in CKD patients include severe infection, hypovolemia, heart failure and renal toxicity medicine.

Objective To evaluate the effects of the chronic Keshan disease's self-management in Liangshan Prefecture of Sichuan Province. Methods According to "The Serf Management Program of Chronic Keshan Disease in Liangshen Prefecture of Sichuan Province", 56 chronic Keshan disease patients were selected in the personalized self-manngemant evaluation under the instructions by endemic disease specialists and the rural doctors. Evaluation was based on changes of indexes such as the clinical symptoms, general health conditions, the electrocardiogram, X-ray, the heart function, etc, before treatment and 3 and 6 months following the treatment. Results Clinical signs and symptoms of the patients were significantly improved 3 and 6 months after the treatment, and the improvement was more obvious 6 months than 3 months following the treatment(P<0.05 or< 0.01). After treatment for 3 months, the patients'electrocardingram and heart function did not show obvious change (X2=0.05,039, P0.05); hut obvious improvements Eexcept X ray results(X2=0.61 ,P0.05)] were seen 6 months after treatment (X2=4.36,16.84, P<0.05 or<0.01). Altogether, among the 56 patients evaluated after treatment for 6 months, none achieved the clinical cure standard, 26 cases(46.3%) showed significant improvement, 17 cases (30.4%) were stable, 5 cases (8.9%) were aggravated,one case (1.8%) lost contact, and 6 cases (10.6%) died. Conclusion The project of the chronic Keshan disease's self-management is suitable for the present situati,on of the endemic regions and can he introduced to many places in our country.

Objective To stratify the risks of patients with acute pulmonary embolism (APE) and pulmonary hypertension (PH) by dynamic pulmonary perfusion imaging (DPPI) and pulmonary perfusion imaging (PPI). Methods From October 2007 to February 2009, 20 healthy volunteers ( 12 males, 8 females; mean age =48.47 ±13.47 years) and 31 APE patients (21 males, 10 females; mean age =47.68 ±18.06 years; from October 2007 to July 2009) were included in the study. DPPI and PPI were performed in all subjects. Percentage of perfusion defect scores ( PPDs% ) were calculated by semi-quantitative analysis of PPI. Risk levels were defined according to PPDs% calculated from PPI: normal (PPDs% =0); very low risk (0 ＜ PPDs% ≤10% ); low risk (10% ＜ PPDs% ≤20% ); moderate risk (20% ＜ PPDs% ≤40% );high risk (40% ＜ PPDs% ≤60% ) and very high risk ( PPDs% ＞ 60% ). Lung equilibrium time (LET)was calculated on region of interest (ROI) drawn over DPPI. Clinical risk was scored by Aujesky method.The t-test, ANOVA and correlation analysis were used with SPSS 13.0 software. Results ( 1 ) LET in healthy volunteers and APE patients was ( 12.18 ± 3.28) and (32.90 ± 14.29) s respectively (t = 6. 81,P ＜ 0. 01 ). (2) The correlation coefficient, coefficient of determination between LET and PPDs% in APE patients were 0.93 and 0. 87, respectively. The correlation coefficient between LET and clinical risk score was 0.86. (3)The mean LET of APE patients in very low risk (n =5), low risk (n = 12), moderate risk (n=9), high risk (n=4) and very high risk groups (n=1) were (19.59 ±0.04), (25.03 ±0.08),(36.07 ±0. 10), (57.15 ±0.06) and (70 ±0.00) s, respectively. There was significant difference among APE patients with different risk levels (F =16. 78, P ＜0.01). Conclusions ( 1 ) DPPI was a reliable, convenient and non-invasive method for the evaluation of PH in APE. (2) Combined LET of DPPI and PPDs% of PPI was valuable for risk stratification and prognosis estimation in APE patients.

OBJECTIVE: To investigate and analyze the changes of postmortem human biochemical indexes. METHODS: Subclavian venous blood samples were collected from 81 cases of traffic fatalities. Thirteen blood biochemical indexes including liver function (ALT, AST, TBIL and DBIL), renal function (UA and Cr), cardiac function (CK, CK-MB and LDH), electrolytes (K+, Na+ and Cl-), and glucose (GLU) were tested by Roche cobas c311 automatic biochemical analyzer. The descriptive analysis was made by SPSS 17.0 statistical software. RESULTS: The values of ALT, AST, CK, CK-MB, LDH and K+ were higher than normal reference values with more fluctuations. The values of TBIL, DBIL, UA, Cr, Na+, Cl- and GLU were relatively stable with less fluctuations. CONCLUSION The postmortem human blood biochemical indexes of liver function, renal function, cardiac function, electrolytes and glucose could be affected by the factors, especially hemolysis and autolysis. The biochemical indexes, particularly enzymes, increased significantly with higher standard deviation.
