On the basis of outpatients' medical records concerning primary liver cancer (PLC), data of 552 patients (with 2020 effective prescriptions) from the Outpatient Department of Changhai Hospital treated by Professor Ling Changquan were collected. The nature, flavor and meridian distribution of the herbs used in the prescriptions were summarized by frequency method, and the features of the herbs used according to syndrome differentiation were analyzed by logistic regression. The couple herbs used were analyzed by cluster analysis. All the data were analyzed in combination with the experience of the specialist. It showed that most of the frequently used herbs were herbs for invigorating the spleen to promote appetite, removing toxic materials to inhibit tumor growth, and activating blood circulation to dissipate blood stasis. These herbs are mostly of plain or cool nature, and mainly of sweet, bitter, or acrid taste. It also showed that the most frequently used herbs for qi deficiency were Astragalus membranaceus, Atractylodes macrocephala, and Pseudostellariae; Caulis Spatholobi and Chinese jujube for blood asthenia; Fructus Corni and Ophiopogon japonicus for yin deficiency; Agastache rugosa, Semen Plantaginis and Poria for water-dampness; cape jasmine fruit and baikal skullcap root for heat excess; peach seed and Radix Paeoniae Rubra for blood stasis; Curcuma wenyujin, Akebia trifoliata and Bupleurum chinese for qi stagnation. A total of 19 pairs of couple herbs were summarized by the cluster analysis.

BACKGROUND:It is confirmed that the characteristics of soft and hard tissue development vary largely in different vertical facial types, which reflect the development trend of the patients and the control ing degree on anchorage.
OBJECTIVE:To evaluate the influence of different vertical facial types on the aesthetic evaluation of facial profiles in young females, and analyze the perception of facial attractiveness from different people.
METHODS:Three beautiful females, with high, average and low mandibular angle, respectively were selected according to the measurement data of projection and the orthodontist’s aesthetic appreciation. They were yel ow race, bilateral facial appearance was basical y symmetrical, and no other maxil ofacial disease was found. They also received no orthodontic or orthognathic treatment. The profile digital photographs and cephalograms of three females were col ected. The positions of soft tissue lip and soft tissue chin were altered incremental y with Dolphin Imaging and Management software. Twenty-five new pictures were generated by the smal scale (2 mm per unit) modification in the sagittal direction. By using“acceptable facial appearance”as a filter, 15 orthodontists selected 11 from 25 pictures. Fifty parents of orthodontic patients, 50 orthodontic patients, and 50 amateurs were taken as the evaluators for subjective aesthetic ratings and for the assessment of the influence of vertical facial types on the facial profile attractiveness.
RESULTS AND CONCLUSION:With low and average angle, straight profile, slightly protrude chin was perceived to be beautiful. With high angle, straight profile, slightly protrude profile was perceived to be beautiful, and evaluation results are consistent between men and women. Evaluators are in agreement when it comes to evaluating the perception of facial attractiveness of three different vertical facial types profile in young females. They also have certain difference in aesthetic tendencies, but when it comes to straight profile they share the same preference. Although different vertical facial types profile has an impact on the profile of lip and chin, but it can’t represent the aesthetic preference of al evaluators.

Objective To explore the regulation of Bub1 mRNA expression in endometrial carcinoma cells by estrogen and paclitaxel. Methods The high differentiated endometrial adenocarcinoma cells ( Ishikawa cell line) were cultured in DMED/F12 supplemented with 10% fetal bovine serum(FBS) or phenol red-free DMED/F12 supplemented with 5% dextran-charcoal FBS (dcFBS). Firstly, the cells were stimulated by 10 nmol/L estradiol (17β-E2 ) or no hormonal stimulation as control group, and the cell proliferation was quantified at 24, 48 and 72 hours using cell counting kit-8 (CCK-8) method. Then the cells were stimulated with different concentrations of 17β-E2 (0.1, 10, 1000 nmol/L) at different periods (5,15,30 minites and 2,4,8,12,16,24,30 hours), the expression of Bub1 mRNA was detected by real-time quantitative PCR. Ishikawa cells were cultured with non-serum DMEM/F12 to be synchronized, and then were treated with different concentrations of paclitaxel( 10,100 nmol/L) for 8 and 24 hours. While, nonsynchronized Ishikawa cells were exposed to 100 nmoL/L paclitaxel for different periods(4, 8, 16, 24,48 hours), and real-time quantitative PCR was also used to detect the expression levels of Bub1 mRNA.Data were presented as folds change relative to control group, in which values ＜ 1 were down-regulated, and those ＞ 1 were up regulated. Results The proliferation rate of cells in the presence of 17β-E2 was significantly highter than that of the control group after treated 24 hours (A value: 0. 70 ±0. 08 vs. 0. 86 ±0.10, P = 0.049). Time-dependent experiments revealed that addition of 17β-E2 could increase cell numbers during 72 hours period, while the expression level of Bub1 mRNA was decreased in Ishikawa cell.Dose-dependent experiments revealed maximal estradiol stimulation effects at 10 nmol/L( P = 0. 020). After being treated with serum-free culture, Ishikawa cells were exposed to 10 nmol/L paclitaxel for 8 and 24 hours, and the expression of Bubl mRNA decreased (0. 403 ± 0. 008 vs. 0. 775 ± 0. 144, P = 0. 251 ).Compared to the control cells, the mRNA expression levels of Bub1 in cells treated by paclitaxel for 8 hours was significantly decreased ( P = 0. 009 ), while there was not significantly decreased at 24 hours ( P =0. 396). When exposed to 100 nmol/L paclitaxel for 8 and 24 hours, the expression of Bubl mRNA was also decreased(0. 697 ±0. 017 vs. 0. 850 ±0. 004, P =0. 061 ). Compared to the control cells, Bub1 mRNA expression was also significantly decreased (P = 0. 038 and P= 0. 019, respectively). While with serum freetreatment culture, when Ishikawa cells exposed to 100 nmoL/L paclitxel for 4, 8, 16, 24 or 48 hours, the expression of Bub1 mRNA significantly increased ( 1. 127 ± 0. 105 vs. 1. 614 ± 0. 154 vs. 2. 092 ± 0. 179vs. 1. 381 ± 0. 061 vs. 1. 519 ± 0. 182, P = 0. 002 ), of which was signicantaly increased at 16 hours treatment. Conclusion Bub1 exrpession could be regulated by estradiol and paclitaxel, in which deregulated Bubl expression may contribute to chemotherapeutic efficacy of paclitaxel.

Objective To study the male reproductive ability of male rats with Toxoplasma gondii ( Tg) infection and investigate the variation of Toxoplasma infection in seminal plasma of infertile patients and explore its mechanism. Methods Thirty SD rats were randomly divided into 3 groups. The rats in the Toxoplasma infection group were administrated intraperitoneally with tachyzoites of Tg. in a dosage of 2 × 10~ 5/ml(2ml) , the rats in the treated group were administered with the same dosage of the tachyzoites and from the second day after the infection they were treated with 200 mg/kg azithromycin for 7 days, and the normal group was given physiological saline. Nine weeks after the infection, the serum sex hormone level, number,vitality, activity and quantity of spermatozoa and activities of enzymes in testa's of the testicular tissues were determined in the male rats. The female rats infected with Tg were matched with normal female rats at a ratio of 1: 2 for one week, and on the 21st day of pregnancy, the number of corpora luteum, sex ratio and the weight, body length and tail length of fetus were measured. The ELISA method was used todetermine the seminal plasma's anti-Tg IgG antibody of the 169 patients with infertility and 35 males with normal fertility. Meanwhile the NO levels in their semina were determined by means of nitric acid reducase. Results The number, activity .vitality, serum level of sex hormones were all lower in the infected rats than those in the normal and treated groups. The number of fetus in the pregnant rats matched with the infected male rats was significantly fewer, but the average body weight, body length, tail length of the fetuses and sex proportion showed no significant difference in comparison with those of the control group. The anti-Toxoplasma gondii antibody positive rate in the masculine infertility patients was 18.35% , being significantly higher than 2. 86% in the normal fertility group(P < 0.05 ). The mean NO level in the semina from the infertility group was (146.68 ± 38. 87) μnol/L , which was significantly higher than (84.92 ± 26.72) μnol/L( P < 0.01) in the fertility group. Conclusion Toxoplasma gondii infection can cause certain influences on the male reproductive ability.
