Dietary intake and biochemical parameters of zinc nutritional status in 270 pregnant women and 44 nonpregnant women have been studied and the results were as follows: 1.Dietary zinc intake was about 60% of RDA in both groups.2.The mean plasma Zn concentration declined progressively during gestation; the mean SOD activities and plasma Cu/Zn and alkaline phosphatase activities increased progressively.3.The zinc nutritional status of pregnant women in Beijing was poor. Using plasma Zn concentration less than 10.71 ?mol/l as a low limit, the incidence of zinc deficiency was 6.5%, 20.2% and 25.7% at each of three trimesters respectively.4.Plasma Zn concentration is more sensitive in evalution of nutritional status than hair Zn concentration. Plasma Cu/Zn could reflect zinc nutritional status. The mean SOD activities had similar trend with plasma Zn during pregnancy, and positive correlation with plasma Zn in second trimester (r= 0.2236,P

Objective To search for the CT and MRI morphological changes in the child patients with cerebral palsy. Method The CT scranning and MRI were carried out in 150 child patients with cerebral palsy, andthe results were analysed. Results In 150 cases, 97 cases (54.6 per cent) have abnormal findings of CT scranning. Diffuse ence-phalatrophy (42 cases), encephalomalacia focus (24 cases) porencephaly (9 cases), and localized ence-phalatrophy (7 cases) ect are the common CT morphological changes in the patients with cerebral palsy.In the 53 patients with normal findings of CT scranning, MRI was carried out for 30 cases and 25 cases(83.3 per cent) were abnormal. The delayed myelinogeny of white matter of brain is the main MRI mor-phalogical abnormality. Conclusion CT scranning and MRI have important value on the etiological diagnosis for child patientswith cerebral palsy. The combination of them can improve the diagnostic accordance rate.

Objective:To analyze the impact of NBP on the expression of HSP 70 and TLR4 in the rat with ischemia-reperfusion.Methods:The 144 rats were divided into 3 groups,Sham group,IR group and NBP group.The 3 groups were divided into 4 groups again according to the time of reperfusion (6h,12h,24h and 48h).The intraluminal ischemia-reperfusion model was made by improved Longa.When the model was made successfully ,the rat in NBP group was gave oral NBP immediately while the IR and Sham group was gave oral NS.The neurological deficit scores , number of apoptotic cells , expression of HSP70 and TLR4 were compared during the 3 groups.Results:The neurological function ,apoptosis,the expression of HSP70 and TLR4 in NBP group at any reperfusion time were statistical lower than in IR group.In all the infusion periods,apoptotic cells in IR and NBP group were significantly higher than that in the Sham group.In all the infusion periods ,the positive cells in IR and NBP group were significantly lower than that in the Sham group.Conclusion:NBP can protect the function of neuron by improving the inhibition of HSP 70 and TLR4.

A monoclonal antibody (McAb) 3H11 against gastric cancer with high positive rate, high selectivity and high affinity was obtained. 131 I Labeled McAb 3H11 was injected into gastric cancer-bearing nude mice, and the tumor/liver ratio, localization index, ID%/g could reach 8.26?1.26, 6.08 + 1.51, 11.00?2.62, respectively. Moreover, McAb 3H11 conjugated with 131 I could increase the cytotoxicity to tumor xenografts and decrease the side effects. The radioimmunoimage was carried out in 19 cases with gastric cancer, and positive image was obtained in 16 cases (84.2%). The radioimmunoguided surgery of gastric cancer was successfully done by submucous injection of labeled McAb 3H11 through endoscope. The sensitivity, specificity and accuracy for evaluation of tumor infiltrated gastric walls were 94.6%, 96.7% and 95.9%, respectively. The sensitivity, specificity and accuracy for identification of metastatic lymph nodes were 99.2% ,97.7% and 98.8%, respectively.

OBJECTIVETo investigate the correlation between drinking behavior and polymorphism combination of extracellular superoxide dismutase (EC-SOD) and aldehyde dehydrogenase 2 (ALDH2) genes and oral squamous cell carcinoma.

METHODSThe genetic polymorphisms of EC-SOD and ALDH2 were analyzed by polymorphism-polymerase chain reaction technique in peripheral blood leukocytes of 750 oral squamous cell carcinoma cases and 750 non-cancer controls.

RESULTSThe frequencies of EC-SOD (C/G) and ALDH2 variant genotypes were 38.27% and 69.47% in oral squamous cell carcinoma cases and 21.07% and 44.40% in healthy controls, respectively. Statistical tests showed significant difference in the frequencies between the two groups (P < 0.01). The risk of oral squamous cell carcinoma with EC-SOD (C/G) was significantly higher than that of controls (OR = 2.32). Individuals carrying ALDH2 variant genotypes had high risk of oral squamous cell carcinoma (OR = 2.85). Combined analysis of the polymorphisms showed that percentages of EC-SOD (C/G)/ALDH2 variant genotypes in oral squamous cell carcinoma and control groups were 30.67% and 6.80%, respectively (P < 0.01). Individuals carrying EC-SOD (C/G)/ALDH2 variant genotypes had high risk of oral squamous cell carcinoma (OR = 8.13). The drinking rate of the case group was significantly higher than that in the control group (OR = 2.70). Statistical analysis suggested an interaction between drinking and EC-SOD (C/G) and ALDH2 variant genotypes, which increase risk of oral squamous cell carcinoma (OR = 25.00).

CONCLUSIONEC-SOD (C/G) and ALDH2 variant genotypes and drinking are the risk factors in oral squamous cell carcinoma, which could carry out a coordinated attack of oral squamous cell carcinoma.
