Academic Journal of Second Military Medical University 2006;27(11):1229-1231
Objective: To investigate the changes of oxygen metabolic parameters and blood glucose concentrations during perioperative period of orthotopic liver transplantation. Methods: The blood gas, cardiac index (CI), mixed venous oxygen saturation (SvO2), oxygen delivery (DO2), oxygen consumption (VO2), oxygen extraction rate (O2ER), and arterial blood glucose were measured at defined time points (before anesthesia induction, 30 min before anhepatic period, 5 min after anhepatic period, 30 min after anhepatic period, 5 min of neohepatic period, 30 min of neohepatic period, and postoperation) in 50 patients receiving liver transplantation. Results: Compared with those before anesthesia induction, no significant changes in CI, SvO2, DO2, VO2, and O2ER were found in pre-anhepatic period. CI, VO2, and DO2 decreased significantly at the early 5 min of the anhepatic period (P<0.05); VO2, DO2, and O2ER decreased significantly at the 30 min of the anhepatic stage (P<0.05). SvO2, DO2, and VO2 increased, but O2ER decreased significantly at the early 5 min of the neohepatic stage (P<0.05). DO2, VO2, and O2ER increased significantly at the 30 min of the neohepatic stage (P<0.05). During preanhepatic stage the blood glucose levels increased progressively but were lower than those during anhepatic stage. During neohepatic stage, blood glucose decreased abruptly but was still higher than the normal level (P<0.05). Conclusion: It suggests that serious imbalance of oxygen metabolism exists during liver transplantation, especially in anhepatic and early neohepatic stages. Blood glucose increases during the preanhepatic stage, reaches the peak during the anhepatic stage, and then decreases gradually.

Objective To study the methods of clinic diagnosis and treatment for chronic lumbar pain induced by lumbo-sacral compartment syndrome. Methods Thirty-three patients with chronic lumbar pain induced by lumbo-sacral compartment syndrome were diagnosed by physical, radiological examination and intra lumbo-sacral muscle compartmental pressure measurement. 33 patients consisted of 15 men and 18 women, with the mean age 42.3 years, and mean duration of chronic lumbar pain was 27 years. Lumbar erector spinae osteo-facial compartment was decompressed using mini-invasive surgery. Lumbar and abdomen muscles were rehabilitated extensively after operation. Results After operation, symptoms of low back pain were alleviated significantly, and walking distance were promoted as well. Post operative flexion and extension of lumbar spine were increased to (15??0.5?) and (7??0.7?) respectively. Intramuscular pressure in rest state, during movement and no more than 6 min after movement was (6.8?0.8), (162.3?12.35) and (7.1?0.6) mm Hg respectively [before operation was(10.4?0.9), (187.1?11.16) and (13.2?1.3) mm Hg respectively, P

ve To study the effects of extremely low frequency electromagnetic fields (ELF EMFs) on lipid peroxidation of myocardium in rats. Methods The activities of superoxide dismutase (SOD) and the contents of malonaldehyde (MDA) of the myocardium tissue of rats under the different conditions such as healthy state, my-ocardiac ischemic state and lead-exposure state before and after ELF EMFs exposure were determined respectively. Results ELF EMFs exposure didn't induce significant changes of SOD activities and MDA contents in myocardium of healthy rats, but caused the SOD activities of myocardium of lead-exposure rats to decrease from (31.24?1.08)U/mg prot before exposure to ELF EMFs to (29.20?1.14) U/mg prot after exposure to ELF EMFs (P

The single nucleotide polymorphisms (SNP) of vitamin D receptor (VDR) gene were determined by BsmI restriction endonuclease analysis and quantitative ultrasonography indexes (QUI) of calcaneum were measured in Tibetan women. The results showed that there were no statistical differences between QUI of different genetypes and between distribution frequencies of gene types in young women and menopausal women. And it was found that the SNP of VDR by BsmI restriction endonuclease analysis was not relevant to bone mass acquisition and rate of bone mass loss.

Objective To investigate the relationship between activity of plasma platelet-activating factor acetylhydrolase (PAF-AH)and insulin resistance (IR) in patients with polycystic ovary syndrome (PCOS). Methods From Oct. 2006 to Jan. 2008, 105 PCOS patients undergoing treatment in Department of Obstetrics and Gynecology of Second Hospital affiliated to West China University were enrolled in the study, among 53 cases with homeostatic model assessment IR (HOMA-IR) exceed or equal 2.77 as IR-PCOS group and 52 cases with HOMA-IR less than 2.77 as non IR-PCOS group. In the mean time, 53 infertile women due to fallopian tube or husband factors were chosen as control group. Plasma PAF-AH activity, high-density lipoprotein-associated PAF-AH (H-PAF-AH) activity, low-density lipoprotein-associated PAF-AH (L-PAF-AH) activity, the ratio of L-PAF-AH to H-PAF-AH activity were measured and compared among three groups. The method of Pearson correlation analysis and stepwise multiple regression analysis were used to study the relationship between the ratio of L-PAF-AH to H-PAF-AH activities and hormonal and metabolic parameters. Results (1) Plasma PAF-AH activity [ (0.055±0.012) mmol· L~(-1)·min~(-1)], L-PAF-AH activity [(0.052±0.012) mmol·L~(-1)·min~(-1)], and the ratio of L-PAF-AH to H-PAF-AH activity (23±6) in the IR-PCOS group were significantly higher than those at control group [(0.050±0.009) mmol·L~(-1) ·min~(-1), (0.047±0.009) mmol·L~(-1)·min~(-1) and (18±4)] and non-IR-PCOS group [(0.050±0.0012) mmol·L~(-1) ·min~(-1), (0.048±0.012) mmol·L~(-1)·min~(-1) and (18± 5 ), P <0.05 ]. The ratio of L-PAF-AH to H-PAF-AH activities at IR-PCOS group was also significantly higher than those at Non IR-PCOS and control group after correction for body mass index (P<0.01). (2) Pearson correlation analysis showed that the ratio of L-PAF-AH to H-PAF-AH in PCOS patients was positively correlated with atherogenic index, age, body mass index, waist-to-hip ratio, HOMA-IR, triglyceride levels, fasting insulin levels, fasting glucose levels, low density lipoprotein cholesterol and total cholesterol (r=0.644, 0.247, 0.296, 0.212, 0.356, 0.587, 0.377, 0.375, 0.292 and 0.199, respectively, P<0.05), and negatively correlated with high density lipoprotein cholesterol (r=-0.510, P<0.05). The multiple stepwise regression analysis showed that atherogenic index and triglyceride were significant variables for the ratio of L-PAF-AH to H-PAF-AH activity (standardized coefficient, β=0.515 and 0.201, respectively, P<0.05). Conclusion The elvated L-PAF-AH activity may be associated with IR in PCOS patients, and the increased ratio of L-PAF-AH to H-PAF-AH activities may be a potential marker of inflammation in the patients.

Objective:To study the inhibitory effect of clarithromycin on angiogenesis induced by b-FGF. Methods:TheMatrigel implant assay was used. Matrigel (500?l) containing b-FGF and heparin were injected subcutaneously into the ab-domen of mice and were harvested 5 d later. The amount of hemoglobin and micro-vascular area present in the implant weremeasured and cotnpared. The mice were given either CAM (study group) or the same volume of glucose (vehicle group) oncea day by gastric intubation. Treatmen started 3 d before Matrigel implant and continued until the end of study. Results:Clar-ithromycin reduced hemoglobin content and micro-vascular area in Matrigel implant at high dosage(≥40 mg/(kg?d). Con-clusion:These data demonstrate that clarithromycin is a potent inhibitor of angiogenesis and may has possible therapeutic value in controlling pathologic angiogenesis.
