Objective: Based on the same clinical laboratory automatic blood coagulation analyzer method comparison of different brands. Discuss different between blood coagulation analyzer test results are comparable or check whether the deviation of the results in the permitted range. Method:collecting 112 cases of fresh plasma specimens, using ACL ADVANCE and Sysmex CA7000 two kinds of blood coagulation analyzer, respectively prothrombin time (PT), activated partial prothrombin time (APTT), thrombin time (TT) and fibrinogen (FIB), and compare the results, to medical decision level of judging system error detection system for clinical result, and calculate the two blood coagulation instrument testing results of the correlation coefficient and linear regression equation. Results:the ACL ADVANCE and Sysmex CA7000 blood coagulation analyzer test of PT, APTT, TT and FIB result comparison, there were no statistically significant difference (t=0.974, t=0.649, t=0.765, t=1.163;P>0.05), the correlation coefficient respectively;Medical decision level of system error were less than half the total margin of error. Conclusion:to the ACL ADVANCE as standard test system, Sysmex CA7000 determination results have clinical acceptability, two blood coagulation test results with good correlation. Should be conducted on a regular basis in the same laboratory coagulation analyzer compares different experiments, to ensure the comparability of the same in the laboratory test results.

Objective To study the effects of diabetes on hippocampal synaptic plasticity in perforant path-dentate gyrus pathway (PP-DG) in rats. Methods 70 SD rats( 180±20) g were divided into 3 groups at random: control group, type1 diabetes group (DM1)and type2 diabetes group (DM2). After Morris water maze test, 15 rats that showed worse spatial memory ability were selected in each model group to investigate the variation of paired-pulse facilitation (PPF) and the range of synaptic plasticity. Field potentials were recorded in the dentate gyrus of the dorsal hippocampus by stimulating the perforant path. Results Contrast to the control group, diabetic rats' hippocampal LTP were depressed (P<0.05), and type1 diabetic rats' LTP reduced much more. Diabetic rats' PPF ratio was reduced contrast to the control group (P<0.05). Conclusion Type1 and type2 diabetes impaired synaptic plasticity of hippocampal PP-DG pathway in rats, which conformed the results of water maze test.

Objective: To explore the relationship between prenatal anxiety and cesarean section (c-section) with non-medical indication.
Methods: Nested case-control study was used to analyze the risk factors for c-section with no medical needs: 433 pregnant women with gestational age longer than 24 weeks were enroled in this study. According to the mode of delivery, we divided them into a vaginal delivery group, a c-section group without medical need and a c-section group with medical need.
Results: The c-section rate was 62.1%, 55.8% of which was c-section without medical need at family request. The score of state anxiety (S-AI) and trait anxiety (T-AI) was 42.53±11.04 and
44.40±10.23 respectively, much higher than that of normal population. After the adjustment of maternal social economic status and other prenatal statuses for this pregnancy, the prenatal anxiety was still associated with c-section with non-medical indication. The adjusted odd ratio for prenatal anxiety state, prenatal trait anxiety state and c-section with non-medical indication was 1.41 (95%CI: 1.06-1.87) and 1.23 (95% CI: 1.08-1.40), respectively.
Conclusion: Prenatal anxiety state is a risk factor for c-section with non-medical indication.

AIM: To understand the influence of national constitution monitoring on sports behavior, attitude and physique of the investigators. METHODS: The study was performed at the Constitution Monitoring Center of Chenzhou Sports Bureau from March to December 2005. 285 public servants of Chenzhou were enrolled as investigators for the first study in 2005 and the second after 10 mouths with questionnaire. Age was accorded with the first measurement. 283 valid data were included (168 males and 115 females), because 2 could not participate in the constitution measurement. Questionnaire in 2006 involved individual physical awareness, behavior, attitude, participating rate, and whether doing the questionnaire according to the physical exercise prescription in the first monitoring. RESULTS: Significant differences in cardiovascular function, strength and sensitivity were detected between testees and national average value, especially in males and middle-age persons and youth. Nine months later, significant difference was found after paired test, step test and in vital capacity improvement. Improvement in other indexes had differences in age and sex. CONCLUSION: The measurement on national constitution is good for realizing their own state of health, improving their sports consciousness, increasing their frequency of doing sports greatly, and improving the physical state, especially for middle-aged and elder persons.

Objective To evaluate the influence of partial parenteral nutrition on serum osmotic pressure,blood glucose,(biochemistry),bilirubin metabolism,immune function,growth and development of premature infants.Methods Seventy premature infants were randomly divided into control group and study group.On the base of enteral feeding,study group were offered parenteral nutrition, while the control group were supplied 10% glucose, fluid and electrolytes. Simultaneously, relevant indices were measured in 2 groups.Results 1.There were no significant difference in serum osmotic pressure,blood glucose and biochemistry before and after parenteral nutrition. 2.There were no significant difference in emerging and lasting time of jaundice between 2 groups.3.Serum IgG,IgA,IgM,C_3,CD4 and CD4/CD8 in study group were significantly higher than those in control group. 4.In study group the time of hospitalization and birth-weight regain were significantly shorter than those in control group.Conclusions There is no significant influence on serum osmotic pressure,blood glucose, biochemistry and bilirubin metabolism during partial parenteral nutrition. Parenteral nutrition may help gain weight, shorten the time of hospitalization, and improve immunological function of neonates.

Partial pancreatectomy was performed in a female patient with islet cell nodular hyperplasia, who repeatedly suffered from hypokalemia and hypoglycemia without diarrhea.After surgical operation,her symptoms were relieved.

Hypoxia-inducible factor 1 ( HIF-1 ) can receive and conduct signals under hypoxia,so it participates in the transcriptions of some genes induced by hypoxia.Hypoxia can cause an increasing expression of HIF-1 α in endomettial carcinoma,which might work on angiogenesis,glycometabolism,invasion,prolifera-tion,apoptosis,differentiation and prognosis of tumor.HIF-1α attracts more and more attention in recent years,detection of HIF-1α in endometrial carcinoma may be useful for its therapy.
