The relationship of the nose tip position and the skull figures which were measured from the lateral craniographs in 49 ladies of 17～19 age living in Shenyang was studied. The figures measured on craniographs were analyzed by multiple stepwise regression analysis on IBM-PC/XT computer, and the regressoin equations for estimating the nose tip position of female in Shenyang were obtained. Cases in which the errors were within 2 mm were 71.43 to 77. 55 percent.

Nomegestrol acetate, 19-norprogesterone de ri vatives, has been used for oral contraception. Recently, studies showed that nom egestrol was a selective estrogen enzyme modulator (SEEM). Nomegestrol is capabl e of inhibiting estrone sulfatase and 17-beta-hydroxysteroid dehydrogenase (17 beta-HSD) and increasing the activity of sulfotransferase,which will provide a new option in the treatment of breast cancer. In addition, nomegestrol has stro ng reversal effects on multidrug resistance in breast cancer cells. In vitro, nomegestrol also exhibits as an inhibitor on endometrial proliferation in uter us. These advances will be introduced in the present review.

Objective To explore the protective mechanism of tea polyphenols (TPs) ion oxidative stress damage of the rat articular cartilage tissue caused by brick-tea fluorosis. Methods One hundred and twenty wistar male rats were randomly divided into 6 groups according to body mass: fluoride group with drinking water containing 100.00 mg/L F-, fluoride plus TPs group treated with 100.00 mg/L F- and 10.0 g/L TPs, fluoride plus aluminum group fed with 100.00 mg/L F- and 200.00 mg/L Al3+, fluoride plus aluminium and TPs group treated with 100.00 mg/L F-,200.O0 mg/L Al3+ and 10.0 g/L TPs;brick-tea group treated with drinking water containing 100.00 mg/L F-,215.00 mg/L Al3+ and 9.2 g/L TPs, which was steeped by the brick-tea;control group treated with tap water. The animals were bred for three months and then sacrificed. The level of SOD,T-AOC and MDA in blood serum were detected,also the level of NO and cytokine IL-1β and IL-6, the expression of iNOS mRNA and protein in articular cartilage were respectively analyzed by RT-PCR and immunohistochemistry. Results Blood serum SOD level in the fluoride plus aluminum and TPs group[(664.009 ± 29.589)kU/L] was higher compared with that in the fluoride group[(625.328 ± 27.199)kU/L], fluoride plus aluminum group[(652.282±13.926)kU/L], although no statistically significant differences was found(P > 0.05) ;blood serum T-AOC level of the fluoride plus TPs, fluoride plus aluminum and TPs group, brick tea group[(10.874 ± 0.721), (11.871 ± 0.941), (10.380 ± 2.747)kU/L] was higher compared with fluoride group, fluoride plus aluminum group [(8.849 ± 1.887), (8.210 ± 1.740)kU/L], the differences all being statistically significant(P < 0.05) ;blood serum MDA level in the fluoride plus aluminum and TPs group[(3.235 ± 0.446)μmol/L] had significances compared with fluoride group, fluoride plus aluminum group [(3.889 ± 0.387), (4.580 ± 0.474)μmol/L, all P < 0.05)];blood serum NO level in fluoride plus Tps group, fluoride plus aluminum and TPs group, brick-tea group[(23.278 ± 2.386), (20.643 ± 2.623), (24.367 ± 6.072) μmol/L] had tatistical differences compared with fluoride group, fluoride plus aluminum group[(32.962 ± 8.268), (34.909 ± 6.288)μmol/L, all P < 0.05];blood serum IL-1β level of fluoride group, fluoride plus aluminum, fluoride plus Tps, fluoride plus aluminum and TPs group and brick-tea group [(4.728 ± 0.297), (4.412 ± 0.229), (4.432 ± 0.285), (4.516 ± 0.351), (4.614 ±0.2270)n/L] did not have inter-group differences (F = 2.314,P > 0.05);the blood serum IL-6 level of fluoride plus aluminum and TPs group, brick-tea group[(7.231 ± 0.596), (7.325 ± 0.290)ng/L] had statistical differences compared with fluoride plus aluminum[(8.256 ± 0.635)ng/L, P < 0.05]. The iNOS mRNA correspondent expression content of fluoride plus Tps group, fluoride plus aluminum and TPs group, brick-tea group(0.482 ± 0.021,0.447±0.021,0.491 ± 0.022) had statistical differences compared with fluoride group, fluoride plus aluminum group (0.562 ± 0.025,0.591 ± 0.020, all P < 0.05). Cells with positive iNOS protein expression of control group were mainly distributed at the surface layer of joint, while the cells of experiment groups were distributed both at the surface layer and the intermediate layer. Conclusions Tea polyphenols could alleviate oxidative stress damage on the articular cartilage, exerting protection against brick-tea fluorosis on rats through cleaning up free radicals, elevating total anti-oxidation capability, diminishing the generation of lipid peroxide.

Three bacteria of decomposing lecithin and 4 bacteria of dissolving aptite were incubated for 4 weeks with sand media respectively. Phosphorus in the sand was extracted with distilled water and measured by different methods. It was found that the bacteria have a quite different ability to release P from the materials. Part of the P released became organic phosphorus compounds in microbial tissue. However, a large amount of the P was reserved in microbial cells in a form of phosphates. The direct measurement of P in the extract by molybdenum blue method would underestimate the capacity of the bacteria to release P from the materials. The correct approach was that the sand was fumigated with chloroform and then digested with acid before the measurement by molybdenum blue method.

0 05).Among them,WT but neither DN, Blank, nor Pio significantly ameliorated the increased concentrations of TGF-a1 and fibro nectin in culture medium induced by HG. Compared with DN and Blank, WT transfect ion significantly attenuated high glucose-caused elevation in c-fos, c-jun and p-ERK expression, reduction in Ⅰ-?B level, and incretio n in nucleus/cytosol ratio of NF-?B, while Pio demonstrated similarly signific ant changes only in p-ERK and NF-?B. No significant difference of GLUT-1 mRN A level was detected between HG groups. Conclusions Overexpressed PPAR?1 can su ppress increased ECM production from glomerular mesangial cells cultured in HG c ondition. Its inhibitory effects on activation of ERK/AP-1 and NF-?B pathways are involved. The further increase of PPAR?activity may have direct anti-fibr otic effect in diabetic kidney.

Objective To investigate the morbidity,clinical feature,diagnosis and therapy of ovarian disease in children.Methods Eighty-two children with ovarian disease were admitted and treated in Nanjing children's hospital from Jan.1992 to Jan.2007,were analyzed retrospectively with age,emergency admissions or not,dwell,pathology and method of operation.Results The age of 82 patients ranged from 1 day to 14 years old and the mean age was 6.7 years old.Thirty-one cases(37.8%) were emergency admissions and 51 cases(62.2%) were routine admissions.Twenty-seven cases(32.9%) were rural patients and 55 cases(67.1%) were urban patients.Forty-five cases(54.8%) were nontumorous disorder,31 cases(37.8%) were benign tumor and only 6 cases(7.4%) were malignant tumor.About the morbidity,12 patients(14.6%)were admitted from 1992 to 1996,24 patients(29.5%) from 1997 to 2001 and 46 patients(55.9%) from 2002 to 2007.Chemotherapy were carried out in 6 cases with malignant tumor in internal medicine,2 cases with sexual precosity kept observation,the others were cured.Conclusions Ovarian disease can occur at any age in children.The clinical manifestation is characterized mainly by acute abdomen.The incidence of ovarian disease of children in urban areas is higher than that children in rural areas.The morbidity continues to show an upward tendency and the pathologic manifestations are mostly benign,laparoscopic operation has obviously superiority.
