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.
2.New light on nomegestrol acetate pharmacological profile
Chinese Pharmacological Bulletin 2003;0(11):-
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.

Objective To establish the solid phase extraction (SPE) with GC/MS technology for fish poi-soning cases to determine five pesticides in fishpond. Methods By three solid phase extraction column including Oasis HLB cartridge, Bond Elut C18 and SampliQ C18, the recovery rate was compared to ex-tract and purify five pesticides in fishpond. The effects of different kinds and dosages of eluents on ex-tract rate were also reviewed. Results Using Bond Elut C18 as solid phase extraction column and 3 mL benzene as eluent, the linear range of mass concentration of five pesticides in fishpond was 1-50 μg/mL, and the correlation coefficient was 0.996 2-0.999 6. The limit of detection was 3.4-26 μg/L and the re-covery was 61.49%-102.48%. The relative standard deviations was less than or equal to 3.01%. Conclu-sion With high sensitivity, good accuracy and precision, SPE -GC/MS has simple and quick operation and less solvent. It can be applied to determination of five pesticides in fishpond.

AIM: To compare the clinical outcomes of pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells to treat and prevent the recurrence of pterygium.METHODS: Fifty patients (60 eyes) were divided into 2groups, and pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells (group A) and pterygium excision followed by transplantation of conjunctiva autograft harvested from counter-side limbus with stem cells (group B) were performed respectively.The surgical time of each case was recorded.RESULTS: All the 50 cases (60 eyes) of pterygium were recruited. The epithelization of cornea and conjunctiva in all cases finished in 2-5d, During the follow-up of 6-12mo, pterygium reoccurred in 2 cases (1 in each group), with no difference in recurrence rate. The mean surgical time was 25± 8min for group A,43± 11min for group B, the difference being statistically significant (P<0.05, t-test).CONCLUSION: Both methods, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells or transplantation of conjunctival autograft with stem cells are effective on treating and reducing the recurrence of pterygium. Compared with the latter, pterygium excision followed by translocation of adjacent conjunctival autograft with stem cells is simpler and easier to perform, and is preferred by the patients too.
