Objective To investigate different factors related to fetal growth restriction (FGR) and to find out the possible causes of FGR with unclear etiologies. Methods Sixty-three women who were suspected of FGR during pregnancy between March 2002 and March 2003 were included in this study. Their age, body mass index (BMI) before pregnancy, and gestational weeks were recorded at the time when they were first diagnosed . Haemoglobin levels, haematocrit (HCT) ,TORCH, anticardiolipin antibody (ACA) , 50 gram glucose challenge test (50g GCT) , 75 gram oral glucose tolerance test (75g OGTT) , leptin levels, systolic/diastolic (S/D) ratio by color doppler monitor and chlamydia trachomatis (CT) were detected and urine culture was done in these groups during the same period. The gestational week, birth weight, body length and the gender were recorded at the delivery period. The FGR group was then divided into two subgroups according to the birth weights: study A group whose birth weights were lower than 10th% of the birth weights at the given gestational weeks (29 cases) and study B group whose birth weights were beyond 10th% (34 cases). The chromosome, leptin, C-peptide, insulin and TORCH of umbilical blood were measured at delivery. The other 25 normal pregnant women were included as control and the same tests were performed accordingly. Results The fasting glucose and the third hour's glucose of 75 gram oral glucose tolerance test of study A were( 3. 8 ?0, 6) mmol/L and (4. 5 ?1. 1) mmol/L. The fetal lepin, C-peptide, and insulin were (7.3 ? 5. 2) ng/ml, (0. 5 ? 0. 3) nmol/L and (2. 3 ? 1. 3 ) mU/L The S/D ratio of umbilical artery, maternal and fetal infection rate of CMV, positive rate of ACA-IgM and the rate of asymptomatic bacteriuria were 3.06, 20.7%, 24.1%, 44.8% and 62.1% respectively. The fasting glucose and the third hour's glucose of 75 gram oral glucose tolerance test of study B were (4. 4 ? 0. 7) mmol/L and (4. 6 ? 1. 1 ) mmol/L. The fetal lepin, C-peptide, and insulin were ( 13. 2 ? 11. 3 ) ng/ml, (0. 7 ? 0. 4) nmol/L and (4.3 ? 3.3) mU/L The S/D ratio of umbilical artery, maternal and fetal infection rate of CMV, positive rate of ACA-IgM and the rate of asymptomatic bacteriuria were 2. 63, 2. 9% , 0% , 5.9% and 44. 1% respectively. The fasting glucose and the third hour's glucose of 75 gram oral glucose tolerance test in control were (4. 3 ? 0. 7) mmol/L and (5. 3 ? 1.2) mmol/L. The fetal lepin, C-peptide, and insulin were( 20. 5 ? 12. 0) ng/ml, (1. 0 ? 0. 4) nmol/L and ( 6. 3 ? 4. 0) mU/L The S/D ratio of umbilical artery, maternal and fetal infection rate of CMV, positive rate of ACA-IgM and the rate of the asymptomatic bacteriuria were 2. 80, 0, 0, 0 and 24. 0% respectively. All these items were significantly higher in study A than those in the control (P

Objective To investigate the reasons for and preventing measures of iatrogenic traumatic pancreatitis after epigastric operations and ERCP.Methods The clinic data of 18 cases of iatrogenie traumatic pancreatitis treated in our hospital from January 1992 to December 2006 were retrospectively analyzed.Results The disease occurred 12 cases after operation and in 6 after ERCP.The iatrogenic traumatic pancreatitis after epigastric operations or ERCP mostly occurred in 1-4 d after the operation.Twelve patients underwent conservative therapy(66.7%)and 6 reoperation(33.3%).Sixteen patients were cured and 2 died of the multiple organ failure after reoperation.Conclusion This complication iS related to the operative skill and expertise.The preventing measures include suitable operative handling,proficiency in technique and drug lessening excretion of pancreatic juice.Conservative therapy is of the first choice unless there is a state of illness alteration.

Object To study the antithombotic portion and bioactive fraction of BUYANGHUANWUTANG (BHT), a decoction of astragalus in combination with peony and several other ingredients. Methods The EtOAc portion of BHT extract was repeatedly separated by chromatography and identified by means of spectral analysis. Results One pterocarpan, (6aR, 11aR) 9, 10-dimethoxypterocarpan-3-O-?-D-glucopyanoside (Ⅴ) and four isoflavones, formononetin (Ⅰ), calycosin (Ⅱ), formononetin-7-O-?-D-glucopyanoside (Ⅲ), and calycosin-7-O-?-D-glucopyranoside (Ⅳ) were identified. Conclusion All five compounds were isolated for the first time from BHT.

In order to understand the academic attitude of medical postgraduates,a questionnaire survey was conducted among full-time postgraduate students.The impacts of working experience,gender,marriage status and source on the academic attitude were analyzed,and the improved suggestion and presumption for academic attitude were provided.

Objective To study the correlationship among plasma lipoprotein associated phospholipase A2 (Lp-PLA2),hypersensitive C reactive protein (hs-CRP) and D-dimer levels of coronary heart disease (CHD) patients.To evaluate their relationship and prognostic values.Methods Case control study.This study enrolled 150 CHD patients,130 age and gender compared health control.The clinical data were recorded and plasma Lp-PLA2,hs-CRP and D-dimer were test.Lp-PLA2 was test by enzyme kinetics method,hs-CRP and D-dimer were test by immunonephelometry method.The blood were also test low density lipoprotein cholesterol and myocardial injury markers such as troponin I,myoglobin,creatin kinase MB.The numbers of lesion coronary arteries were confirmed by percutaneous coronary intervention operation.Student t-test and mann-whitney U test were used to compare two groups datas,analysis of variance was used to compare more than three groups datas,spearman test was used for correlationship analysis between groups.Results The Lp-PLA2,hs-CRP and Ddimer of CHD group were (43.62 ±13.23) g/L,5.09 mg/L(95％ CI:0.56-74.15),173.0 mg/L(95％ CI:103.0-966.5),respectively.They were higher than healthy control group whose values were (21.49 ± 7.63)g/L,2.61 mg/L(95 ％ CI:0.37-45.12),68.0 mg/L (95％ CI:48.0-540.6),respectively.The difference were statistical significant (t =2.69,U =67.52,U =37.84,P ＜ 0.001).After correlation with clinical data,the Lp-PLA2 was correlated to LDL(r =0.487,P ＜ 0.001) and the numbers of coronary artery lesion (r =0.260,P =0.018).D-dimer was correlated to hs-CRP(r =0.263,P =0.011),it was also correlated to NYHA heart function level (F =23.78,P =0.001).Conclusions Lp-PLA2 is important in lipid metabolize,especially in LDL metabolize.Lp-PLAz can be used to predict severity of coronary artery lesion.Hs-CRP correlated to D-dimer level and cardiac injury markers.It stated link between inflammation and thrombosis.D-dimer is increasing with NYHA level.Lp-PLA2,hs-CRP and D-dimer are correlated to coronary artery lesions,they are good prognostic indices for coronary heart disease patients.

Object To study the isomers of amygdalin in BUYANG HUANWU TANG and its production Methods Amygdalin was isolated from both peach seeds and BUYANG HUANWU TANG by using various column chromatography Their structures were identified by the various spectral data Results Amygdalin had been isolated from n BuOH fraction of aqueous extract of BUYANG HUANWU TANG and found to be a pair of D , L epimers and their ration was 1∶1 It was also found that the structures and the ration of D , L epimers of amygdalin in decoction of single peach seed were similar to that in BUYANG HUANWU TANG. The peach seed only gave D amygdalin when it was extracted in 95% EtOH at reflux temperature, and D amygdalin cannot be isomerized when it was treated in water at 100 ℃ Conclusion Isomerization of D amygdalin results from interaction between it and other compounds of peach seed in water at high temperature, and has no evident relation to other constituents in BUYANG HUANWU TANG L amygdalin is a new compound generated due to decoction of peach seed

The changes of rheobase(Rh), chronaxie(Chr), standard electrical quantity(a) and mtensity-duration curve(i. t. c) were studied for understanding the effect of aging on the excitability of sciatic and caudal nerves in Wistar rats of different age. The results show that before grown-up excitability of the peripheral nerves increases progressively with age, after that it tends to decrease. Chronaxie as an index can not reflect the change of excitability of the peripheral nerves correctly.
