Objective To study the relationship between the antigenic titer of anti-A(B) IgG in pregnant women with blood-type O and the incidence of hyperbilirubinemia in newborns with blood-type A or B.Methods The antigenic titer of anti-A(B) IgG were determined in pregnant women with blood-type O whose blood type were incompatible with their mates'.Serological tests for the umbilical blood were analyzed in the neonates with blood-type A or B.The incidence and the pathogenic time of hyperbilirubinemia in newborns were studied by gravidity and test results.Results (1) There was no significant difference in the antigenic titer of anti-A(B) IgG,test results of umbilical blood and the incidence of hyperbilirubinemia between the first and the second pregnancy (P>0.05).(2) With the antigenic titer of anti-A(B) IgG increased,there was significant difference in the positive rate of antibody releasing test to newborns,positive rate of free antibody and the incidence of hyperbilirubinemia (P<0.01).(3) The incidence of hyperbilirubinemia in neonates whose results of antibody releasing test were positive and the antigenic titer of anti-A(B) IgG≤1∶64 were much higher than control group(P<0.01).(4)There was no significant difference in the incidence of hyperbilirubinemia in 3 days after birth (P>0.05).Conclusion The gravidity is not correlative with the antigenic titer of anti-A(B) IgG and the incidence of hyperbilirubinemia in neonates.The risk of hyperbilirubinemia in neonates increases as the antigenic titer of anti-A(B) IgG in gravida ≥1∶32.The incidence of hyperbilirubinemia in neonates become higher as the antigenic titer of anti-A(B) IgG in their mother increasing,however,it has no influence on the onset time of hyperbilirubinemia in newborns.

Objective To study the relationship between antibody-rdeased test and the morbidity of hyperbilirubinemia in newborns.Methods According to the laboratory rules,serological tests were practised with neonatal umbilical blood of 1 013 A or B blood-type neonates delivered by O-type blood mothers.The morbidity of hyperbilirubinemia were grouping studied in 7 days after birth tO the neonates according to test results.Results(1)The morbidity of hyperbilirubinemia neonates with positive antibody release test results was much higher than that of control group(P＜0.01).(2)Of the antibody release test positive results,there were significant differences among the three groups in which the degree of red cell agglutination were different (P＜0.01).(3)Of the antibody-released test positive results,there was no significant difference in the morbidity of hyperbihrubinemia between the neonates sensitized by the anti-A+B IgG and those not sensitized by the anti-A+B IgG(P＞0.05).There had significant difference in the morbidity of hyperbilirubinemia between the neonates with free antibody and those without free antibody(P＜0.01).Conclusion The different results of antibody release test play some role in the clinical judgement whether hyperbilirubinemia of newborns will occur.

Objective To discuss the relationship between the titer of immunoglobulin Ab-A(B) in the O- type-blood pregnant women and the morbidity of hyperbilirubinemia which the A(B)-type-blood neonates developing. Methods The Ab-A(B) titer of the pregnant wives whose blood type was O and didn't match their husbands' was determined. Determine the serology with umbilical blood of the A(B)-type-blood neonates was determined, and the morbidity of hyperbilirubinemia which happened to those antibody-released test positive neonates was determined.Results (1)In the 271 A(B)-type-blood cases,when the pregnant woman's Ab-A(B) titer≥32,from low to high,the positive incidence of the antibody-released test and indirect antiglobulin test heightened remarkably(P

Objective To investigate the expression level of Ezrin and its clinical significance in nontraumatic os-teonecrosis of femoral head. Methods Expression level of Ezrin in 38 patients with nontraumatic osteonecrosis of femoral head ( experimental group) and 16 patients with femoral neck fractures ( control group) were detected by immunohistochemistry and RT-PCR analysis. Results The expression level of Ezrin was significantly lower in ex-perimental group than that in control group (P<0. 05). It was correlated with the Ficat Stage, and had no rela-tionship with gender, age, BMI, profession and etiological factor. Conclusion Ezrin may involve in the develop-ment of nontraumatic osteonecrosis of femoral head, and play an important role in regulation.

AIM: Theaflavins are the major constituent of black tea, and have a lot of pharmacological activities, for example, regulating blood fat, anti-oxygen, anti-tumor, resisting cerebrovascular disease, and so on. Previously, theaflavins' effect on human fat metabolism mostly belongs to macro-analysis, but this experiment try to find out the effect of theaflavins on the differentiation of rabbit mesenchymal stem cells (MSCs) into adipocytes in terms of cells. METHODS: The experiment was completed in the center laboratory of Anhui Provincial Hospital Affiliated to Anhui Medical University from May to September in 2007.①Ten rabbits of cleaning grade and 4-8 weeks old were provided by the animal experiment center of Anhui Medical University. The disposal of animals in process of experiment referred to the ethical standard of animals.②The heparinized rabbits were sacrificed in drugged state, then bilateral femur, tibia and humerus were obtained and their soft tissues were removed, cutting epiphysis of two sides including epiphyseal plate. The MSCs were isolated and cultured with whole bone marrow culture method, inoculated at a density of 2?108 L-1. When the cells grew to the fusion of 80%-90%, digesting and passage culture were performed. Cells of the third generation were collected and inoculated at a density of 1?105/cm2 to be cultured for 2 weeks with DMEM adipocyte-induced liquid, which contained recombinant human insulin 10 mg/L, dexamethasone 10-6 mol/L, and IBMX 0.5 mmol/L. Three groups were set up: adipocytes control group in 1 mL adipocyte-induced liquid; theaflavins group with the 500 ?g/L theaflavins in 1 mL adipocyte-induced liquid; blank group in equal amount of ordinary DMEM culture medium.③The cultured cells of the second generation were selected to draw growth curve; oil O staining was used to identify the induced adipocytes and calculate the differentiation efficiency of adipocytes. RESULTS: ①Cell growth curve: MSCs had vigorous reproductive activity, 1 day of the culture was the cell adaptive phase, 3 days was the increased logarithmic phase, and 8 days was the platform phase. After 8 days, cell proliferation quickly stepped down and cells reduced.②Identification of adipocytes by oil O stain: Lipid droplets in adipocytes were stained into salmon pink, and the nucleus was stained into blue. Most of MSCs in adipocyte control group were induced into adipocytes, the differentiation efficiency was (64.8?4.8)%, while that in theaflavins group was only (32.0?3.4)%. No adipocytes obviously formed in blank control group. CONCLUSION: Theaflavins can obviously inhibit differentiation from rabbit MSCs to adipocytes.

OBJECTIVE: To explore the correlation between syndrome differentiation and CT quantitative diagnosis of fatty liver. METHODS: One hundred and thirteen cases of fatty liver verified clinically accepted plain CT scan after syndrome differentiation (syndrome of stagnation of liver qi and spleen deficiency, syndrome of intermingled phlegm and blood stasis, syndrome of phlegm-dampness blocking internally, syndrome of deficiency of liver and kidney, syndrome of interior dampness-heat), and then the CT values of the liver and the spleen were measured respectively. RESULTS: It was shown that there was a correlation between the syndrome differentiation and the fatty infiltration in the liver. Significant differences of the distribution of fat and the ratio of liver-spleen were found among the five different syndromes (P<0.05). Diffused, mild fatty liver mainly displayed syndrome of stagnation of liver qi and spleen deficiency. CONCLUSION: Syndrome differentiation of fatty liver is correlated with CT quantitative diagnosis, which can be discriminated by the ratio of liver-spleen.

BACKGROUND:Systemic lupus erythematosus is a kind of heterogeneous disease, and the difference of clinical features may also be the risk factors of osteonecrosis besides of treatment with glucocorticoids according to the literature. However, it remains controversial on the risk factors of osteonecrosis in systemic lupus erythematosus patients.
OBJECTIVE:To systematical y review the major risk factors of osteonecrosis in the Chinese patients with systemic lupus erythematosus.
METHODS:The CNKI database, CBMdisc database and Wanfang database were retrieved for the published case-control study literatures on the risk factors of osteonecrosis in the Chinese patients with systemic lupus erythematosus. The literatures met the inclusion and exclusion criteria were included, and a Meta-analysis was conducted by RevMan 5.0 and Stata software. Then, the pooled odd ratio and 95%confidence interval of each risk factor were calculated.
RESULTS AND CONCLUSION:Ten case-control study literatures were included involving 332 cases in the case group and 986 cases in the control group. The pooled odd ratio and 95%confidence interval of each risk factor of osteonecrosis in the Chinese patients with systemic lupus erythematosus were as fol ows:Raynaud’s
phenomenon 3.28(1.69-6.38), dental ulcer 2.95(2.13-4.09), renal involvement 1.21(0.83-1.74), vasculitis 5.64(2.84-11.21), hyperlipidemia 5.11(3.10-8.42), anti-phospholipid antibody 2.32(1.49-3.61) and joints involvement
2.02(1.33-3.07). It has been clear that the glucocorticoids is an independent risk factor of osteonecrosis in the patients with systemic lupus erythematosus. However, it is not the one and only risk factor. The fol owing risk factors of
vasculitis, hyperlipidemia, Raynaud’s phenomenon, dental ulcer, positive anti-phospholipid antibody and joints involvement are the risk factors of osteonecrosis in the patients with systemic lupus erythematosus.

Objective To explore the value of MRI dynamic contrast-enhanced in differentiating adrenal adenomas from nonadenomas with washout rate of enhancement and the increased SI ratio. Methods Thirty-six patients with 41 adrenal masses enrolled into this study. All these masses underwent conventional T 1WI and T 2WI sequence first, and then FMPSPGR sequence through the center of each mass. Precontrast and dynamic contrast-enhanced FMPSPGR scans were preformed after administration of contrast material of Gd-DTPA intravenously. The signal intensity(SI) of masses was measured on the screen by electronic cursor. The washout rate of enhancement and increased SI ratio were compared between adenomas and nonadenomas. The differentiating adrenal adenomas from nonadenomas were carried out based on combination of the washout rate and the increased SI ratio, meanwhile, the sensitivity and specificity of the diagnosis of adenomas were evaluated well.Results The sensitivity and specificity of the diagnosis of adenomas were 74% and 73%,and accuracy was 73% when the washout ratio was used as a indicator at 5 min. The sensitivity and specificity of the diagnosis of adenomas would be improved markedly when the combination of the washout ratio and the increased SI ratio was used as a indicator.The sensitivity and specificity of the diagnosis of adenomas were 95%, 91% respectively,and accuracy was 93%. Conclusion Using MRI dynamic contrast-enhanced based on combination of washout rate of enhancement and the increased SI ratio,the diagnosis and differentiating diagnosis of adrenal adenoma and nonadenoma can be improved.

Hyperuricemia is a risk factor for various diseases, but knowledge on acute hyperuricemia is still not sufficient. The present study was aimed to investigate the effect of acute hyperuricemia on red blood cells from hemorheological point of view, and to provide the reference for clinical treatment. The rats were gavaged with 500 mg/kg hypoxanthine and intraperitoneally injected with 100 mg/kg oxonate to induce the model of acute hyperuricemia. The same volume of blood samples were drawn within time period of 0, 1, 2, 3 and 6 h, respectively, from the inner canthus of rats to measure the serum uric acid, hemorheological parameters and the malondialdehyde level. It was found that in each period of 1, 2 and 3 h, the rats had significantly higher levels of uric acid. The integrated deformation index and relax index were increased. The hemolysis rate was significantly reduced. The plasma malondialdehyde level was obviously decreased at the end of 2 h. The results suggested that short-term elevated uric acid could improve the hemorheological parameters and the lipid oxidative level in red blood cells.
