Objective To investigate the significance of fibrin monomer(FM ) ,D‐Dimer(D‐D) and other blood coagulation indica‐tors detection in the early diagnosis of disseminated intravascular coagulation(DIC) in obstetrics .Methods 90 healthy women with‐out pregnancy(control group) ,270 normal pregnant women including early ,mid‐,late pregnancy(90 cases for each) ,36 early DIC puerperas(early DIC group) were enrolled in the study .FM ,D‐D ,prothrombin time (PT ) ,activated partial coagulation activity (APTT) ,fibrinogen(FIB) levels were detected for those people .Results The levels of D‐D and FM in early DIC group were signif‐icantly higher than those in control group (P<0 .05) ,and PT ,APTT in late pregnant group were significantly shorter than those in early ,mid‐pregnant group and control group ,while FIB was significantly higher ,the difference was statistically significant(P<0 .05) .Conclusion PT ,APTT and FIB can reflect the high blood coagulation state in the late pregnancy ,but can not be used in the diagnosis of early DIC .D‐D and FM have important value for the early diagnosis of DIC in obstetrics .

the effect of maintaining integrity of epithelial cells by increasing occludin protein expression,and the effect is related with the up-regulation of occludin mRNA.

OBJECTIVE To investigate the difference of IgM and DNA for Mycoplasma pneumoniae in respiratory infected children with different age.METHODS Serum samples were tested with ELISA for IgM and molecular beacon based real-time PCR was used to test M.pneumoniae DNA.RESULTS M.pneumoniae DNA was detected in 40% of the patients and the IgM was positive in 11% at the day of sampling and 30% after 7 days,respectively.The difference was of significance(P

To study the effect of soybean isoflavone on liver oxidative stress resulting from 60Co-gamma rays. Methods: Totally 80 normal female Kunming mice were evenly randomized into 5 groups according to body weight: 3 intervention groups, single irradiation group and normal control group. The normal group and single irradiation groups were given 0.5% CMC-Na, and the 3 intervention groups were given different doses of soybean isoflavone (50 mg/kg, 100 mg/kg, 400 mg/kg) respectively for 14 d. The whole body of single irradiation group and intervention groups were subjected to 4.56 Gy 60Co-γ radiation once on the 7th day, and then the mice were killed on the 2nd day and the 7th day after radiation. Results: The CAT activity of liver tissue of 100,400 mg/kg intervention groups and 3 SI groups were significantly increased on the 2nd day and 7th day after irradiation(P<0.05), respectively; the GSH-Px activity of 100 mg/kg SI group was significantly increased(P<0.05) on the 7th day after irradiation; the T-SOD activity of 50 mg/kg SI group was significantly decreased (P<0.05) on the 2nd day after irradiation,while no difference was observed among remaining groups. The MDA content of 100 mg/kg group was significantly decreased on the 7th day after radiation compared with control group, and MDA content of each group subjected to irradiation were increased on the 2nd day after irradiation,but 3 SI groups nearly decreased to normal level on the 7th day after irradiation. Conclusion: The soybean isoflavone can enhance the antioxidant capability of mice, but it does not show a dose-effect relationship.

Objective:To compare the nutritional status of inpatients after enteral nutrition (EN) and parenteral nutrition (PN). Method: A multi-center survey of 1 142 inpatients from the Department of gastrointestinal surgery, thoracic surgery, gastroenterology, respiratory disease, neurology, neurosurgery and the intensive care unit of 6 general hospitals in Beijing and Shanghai was adopted in this study. Body weight (BW), haemoglobin (Hb) and serum albumin (sALB) were compared before and after EN or PN respectively. Results: BW, Hb and sALB all decreased after the nutritional support both in EN and PN groups, but only significantly in BW and sALB (BW: -1.58?2.36 kg/m2 vs -2.09?2.66 kg/m2, P

Objective: To investigate the quality of life (QOL) and its influence factors in the scattered elderly in Shanghai, and to evaluate the effect of nutrition status on the QOL. Methods: Ninty-five randomly-selected elderly were investigated with QOL questionnaire, food frequency questionnaire and 24 h dietary recalls, their nutrition status were awarded by nutrient intake and medical examinations. Results: The percentage of poor, moderate and good QOL were 1.05%, 61.05% and 37.89%. The significant influence factors of QOL were health status, nutrition status, livelihood satisfaction, mentality health, family harmony, medical examination and income. The main nutrition intake of the 95 cases were sufficient, such as energy, protein, but the intake of diet fat and salt were overtaken. The rate of overweight and obesity were 26.3% and 40.0%. Conclusion: Nutrition status is the main influence factor of QOL in the elderly. To improve the QOL of the elderly, health education and balance nutrition guidance should be strengthened.

Objective:To observe the protective effect of tremella polysaccharides (TP) on mouse aging model induced by D-galactose. Methods: Forty male ICR mice were divided into 5 groups (Group A: treated with 800 mg/kg TP; Group B: treated by 400 mg/kg TP; Group C: treated by 200 mg/kg TP; Group D: aging control; Group E: normal control). Except for Group E,other groups were injected with D-galactose [120 mg/(kg?d)] for 60 d to establish subacute aging model. Group A,B and C were treated with 800,400 and 200 mg/kg TP respectively via intragastric (i.g.) administration. Sixty days later,the spleen,heart, kidney and brain were collected to determine MDA, LP, SOD, GSH-Px and contents of hydroxyproline by colorimetry. Expression of P21 in the kidney were detected by immunohischemical technique. Proliferation and transformation of spleen lymphocytes induced by ConA were determined by MTT method. Results: Antioxidants SOD and GSH-Px activity of TP treated groups were higher than aging control group (P

Many data show that hyperhomocysteinemia is correlated with the increased rate of cardiovascular diseases.Yet,there is controversy about the relationship between mild hyperhomocysteinemia and cardiovascular diseases.Lots of study suggest that the concentration of plasma homocysteine was reduced by using folic acid in patients with cardiovascular diseases.But,the effect of folic aicd can not be identified from other factors reducing the concentration of plasma homocysteine.
