OBJECTIVETo study the correlation between arachidonic acid (AA) and acute red blood cells damage in rats, and to build a model with hidden blood loss in vivo, and to explore the pathological mechenism of hidden blood loss.

METHODSA total of 50 male adult Sprague-Dawley rats weighing (200 ± 20) g were randomly divided into five groups (n = 10): control group and four experimental groups. The rats in the experimental groups were given 0.5 ml different concentrations of AA dilu- ents, 5, 10, 20, 40 mmol/L respectively. The blood samples were collected from orbital venous at the beginning and 24, 48, 72 hours after administration. Then the changes of hemoglobin (Hb) ,red blood cell count (RBC), glutathione peroxidase (GSH- PX) activity, total superoxide dismutase (T-SOD) activity and hydrogen peroxide (H202) in the blood samples were tested.

RESULTSSignificant hidden blood loss occurred when the concentration was 10 mmol/L in the experimental group, with the RBC and Hb sharply reduced in blood samples. The Hb and RBC were reduced in all the experimental groups and control group at 24 hours after administration, while in the experimental groups they changed more obviously. The GSH-PX activity, T-SOD activity and H₂O₂were also significantly reduced in all groups, and the changes showed significant differences. The Hb and RBC were relatively stable in the control group and the experimental groups at 48 hours after administration; while GSH-PX activity, T-SOD activity and H₂O₂were all significantly decreased, and the changes in the experimental groups were more notable.

CONCLUSIONElevated levels of AA in the blood causes oxidative stress in the red blood cells, leading to the damage of red blood cells and hemoglobin, which is responsible for hidden blood loss.

0.05).Conclusion MRI is a highly accurate diagnostic tool for detecting tears of the medial and lateral menisci.At present,there is no evidence to ascertain that higher magnetic field strength improves discriminatory power for meniscal tears.

Objective To study the effect of TCM five-tone therapy on chronic fatigue syndrome(CFS).Methods Fifty nine CFS patients were divided into the treatment group(n=30)and the control group(n=29),which received TCM five-tone therapy and common music therapy,respectively for 3 months.Both groups were assessed with fatigue Scale-14,depression status inventory and visual analogue scale.Result After treatment,the treatment group was scored lower than the control group in FS-14,DSI and VAS(all P<0.05).Conclusion TCM five-tone therapy may be more effective in decreasing the CFS patients with fatigue and depression and alleviating their pain symptoms.

ObjectiveTo explore the relations between the alkaline phosphatase(ALP) and the type of cerebral palsy. MethodsThe ALP level of 40 children with different types of cerebral palsy were examined with the Olympus AU-600 apparatus. ResultsThe ALP value of the children with spastic cerebral palsy is normal. The ALP value of the children with athetoid cerebral palsy is higher than spastic cerebral palsy(P<0.001).Conclusions The ALP value can help us to identify the type of cerebral palsy.

Objective To compare the differences of metabolic syndrome (MS) prevalence by using four working definitions and their relationship with obesity-related indicators in first-degree relatives of type 2 diabetes mellitus pedigrees. Methods Totally, 2 372 first-degree relatives from 715 type 2 diabetic pedigrees were selected in this study. Complete laboratory data, including blood pressure, lipid profile and plasma glucose, were collected. The prevalence rates of MS and obesity of four definitions, as defined by National Cholesterol Education Program Adult Treatment Panel Ⅲ (ATPⅢ) in 2005, International Diabetes Federation (IDF) in 2005,Chinese Diabetes Society (CDS) in 2004 aml Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults (JCDCG) in 2007,were analyzed. Results (1)The prevalence rates of MS were 45.40% ,38.74% ,25.08% and 39.29% aecording to four definitions respectively. The prevalence rates of MS were higher in females than in males by using ATPⅢ and IDF definitions (both P<0. 01). (2)The common comhinations of metabolic abnormality was dyslipidemia, hypertension, obesity and hyperglycemia by using four definitions,except in females by using CDS definition. (3)The prevalence rates of obesity were 58.18% ,58.18% ,33.90% and 42.96% acconling to the four definitions respectively. The prevalence rates of MS in obese subjects were 66.59% ,66.59% ,54.85% and 68.99% according to four definitions respectively. (4) Applying the cutoff point for abdominal obesity according to ATPⅢ, IDF and JCDCG definitions, the prevalence rates of abdominal obesity in subjects with body mass index (BMI) <25 kg/m2 were respectively 28.58% and 16.78%, being higher in females than in males(38.90% vs 15.02% ,21.01% vs 11.22% ,both P<0. 01). Conclusion (1)There is significant familial aggregation of MS and obesity,and the first-degree relatives of type 2 diabetic patients are high risk populations. (2) Waist circumference rather than BMI taken as a discriminating component of obesity in MS seems to be clinically more helpful to the early identification and prevention of MS.

Objective To investigate the association between the tumour necrosis factor-α-863(TNF-α-863) polymorphism and gout in Han population from the city of Tangshan.Methods We recruited 80 gout patients and 80 healthy individuals into this study.The polymorphisms of TNF-α-863 site were analyzed by polymerase chain reaction-ligase detection reaction(PCR-LDR).The frequencies of different TNF-α-863 genotypes/alleles were analyzed in the gout group and the control subjects.Results No significant differences were observed in the genotype frequencies(x2=2.8807,P=0.0897) and allelic frequencies(x2=4.2646,P=0.1187) of TNF-α-863 site in the comparison between gout and control groups.Conclusion The result of our study suggests that the polymorphism of TNF-α-863 site may not related to gout in Han population in Tangshan.

Objective To evaluate the association between total fluid intake and the time of urination per day and the risk of bladder cancer. Methods A population-based case-control study was conducted in urban Shanghai, China, during January 1996 to December 1998. The study included 608 incident cases of bladder cancer and 607 age- and sex-matched controls. Unconditional logistic regression models were used to estimate the odds ratios(ORs)and their corresponding 95%confidence intervals(95%CIs)for bladder cancer associated with frequency of urination, after adjusted for age, gender, smoking status, history of occupation with high risk, history of bladder infections, body mass index and other confounding factors. The level of statistical significance was set at 0.05(two-sided). Results No significant trend was observed for the association between total fluid intake, time of nighttime urination and the risk of bladder cancer. Increasing time of urination during daytime was associated with decreased risk of bladder cancer(P for trend=0.014). ORs(95%CIs)for subjects who voided 4 times, 5 times and 6 or more times per day[0.72(0.49-1.05),0.60(0.41-0.87)and 0.62(0.43-0.90), respectively], when compared with those with less than 4times per day after adjustment of confounding factors. Data showed that smokers and nonsmokers who voided at least 6 times per day had the ORs of 0.72(95%CI: 0.45-1.15)and 0.46(95%CI:0.25-0.87)when compared to their counterparts who voided 3 times or less per day during the daytime. Subjects who urinated at least 6 times per day and consumed more than 1500 ml of total fluid per day experienced a significant 57% reduction in risk compared to subjects who urinated 3 times or less and consumed less than 750 ml of total daily fluid intake. Conclusion Increased urination frequency and total fluid intake, especially among those who never smoked might be associated with a reduced risk of bladder cancer.
