This study is to establish the HPLC fingerprint and determine eight components of Callicarpa nudiflora, and provide a scientific basis for the identification and quality control. The Waters sunfire C18 column (4.6 mm x 250 mm, 5 µm) was used and the detection wavelength was 330 nm . The column temperature was 30 °C. The mobile phases were acetonitrile (A) and 0.1% formic acid (B) eluting in a gradient program at a flow rate of 1.0 mL · min(-1). The chromatographic fingerprint similarity evaluation system for tradition Chinese medicine(2012) was used for analysis. C. nudiflora from different samples were of high similarity in fingerprint and the separation of ten components was good. There was an obvious difference between other samples and C. nudiflora leaves. In quantitative analysis, the ten components showed good regression(R2 > 0 999 0) with linear ranges, and their recoveries were in the range of 96.0%-105.0%. The established qualitative and quantitative methods are highly specific, simple and accurate, which can be used for the identification and quality control of C. nudiflora.

OBJECTIVETo explore the protective effect of electroacupuncture (EA) pretreatment on ovarian function in rats with ovulation induction.
METHODSThirty SD female rats were numbered according to random number table. According to vaginal smear method, rats of estrus were divided into a normal group (10 rats) and cohabitated with male SD rats with the proportion of 1:1. With computer-generated random number, the remaining rats were divided into a model group and an EA group, 10 rats in each one. The model of superovulation was established with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) in the model group and EA group. Before model establishment and cohabitation, rats in the EA group were treated with EA at "Guanyuan (CV 4)" and "Sanyinjiao (SP 6)", once for 15 min, for consecutive 7 days. Rats in the normal group and model group received no further treatment. The third day 23:00 pm after cohabitation, blood samples in three groups were collected to test the level of estradiol (E₂) and progesterone (P). After the rats were sacrificed, the HE staining method was applied to observe the morphological changes of ovarian tissue; the immunohistochemical method was applied to measure the expression of vascular endothelial growth factor (VEGF) and its receptor VEGFR-2; the real-time quantitative PCR technique was applied to measure the gene expression of VEGF and VEGFR-2.
RESULTSThe number of ovarian follicle in the EA group was higher than that in the model group and normal group (all P < 0.05); the ratio of corpus luteum size to ovarian size in the EA group was lower than that in the model group (P < 0.01). The ratio of plasma estradiol to progesterone in the EA group tended to be normal group (P < 0.05) and lower than that in the model group (P < 0.01). The protein expression of VEGF and VEGFR-2 in lutein granulosa cell and follicular fluid in the EA group was lower than that in the model group (P < 0.05); gene level of VEGF and VEGFR-2 in ovarian tissue in the EA group was lower than that in the model group (P < 0.05, P < 0.01).
CONCLUSIONEA pretreatment has certain protective effect on ovarian function in rats with ovulation induction, which is likely to be related to regulation of VEGF and its receptor.

Terminal restriction fragment length polymorphism (T_RFLP) analysis is a culture- independent approach for analyzing microbial community in environment. It bases on PCR technology, and its process includes DNA extraction of environmental samples, amplification of genes encoding the 16S rRNA, 18S rRNA or enzymes with fluorescently labeled primers, the restriction enzyme digestion of PCR products, cap- illary electrophoresis and the analysis of T_RFLP profile. It has been proved to be powerful applied on mi- crobial community in environment since developed in 1997. Currently, T_RFLP rarely applied in China, and it has no applications on microbial community analysis of nitrifying bacteria. In this article, the fundamental principle of this technique and the recent applications of T_RFLP on microbial community are summarized; in addition, it illustrates the confinements of conventional culture-dependent of nitrifying bacteria and the foreground of T_RFLP applying on microbial community structure analysis of nitrifying bacteria.

Aim To study absorption characteristics of SM-1 , a novel anti-tumor agent , to provide a research basis for the druggability evaluation of SM-1 and formu-lation design. Methods Caco-2 cell monolayer model and in situ single-pass intestinal perfusion rat model were used to study the absorption characteristics of SM-1 , and the absorption of SM-1 in vivo was evaluated through absolute bioavailability study in rats. Results The results of cell monolayer model showed that cu-mulative absorption and efflux of SM-1 increased line-arly with concentration ( 10 ~40 mg · L-1 ) . There were no significant differences in Papp with different concentrations ( P>0. 05 ) . SM-1 was absorbed mainly through passive diffusion. The intestinal perfusion re-sults showed that Ka and Pef of SM-1 had no significant differences ( P > 0. 05 ) , when the concentrations ranged from 25 to 100 mg · L-1 . SM-1 entered the systemic circulation mainly via on passive diffusion, indicating it is a compound with high permeability. The absorption of SM-1 in duodenum was superior to other intestinal segments ( P <0. 05 ) , there were no significant differences in the jejunum, ileum and colon ( P >0. 05 ) . The absolute bioavailability of SM-1 in rats was 29. 3%. Conclusion The membrane perme-ability of SM-1 is high and it can be absorbed by intes-tine well. The absorption mechanism of SM-1 is pas-sive diffusion, and it possibly escapes from the efflux transporter protein. The absolute bioavailability of SM-1 in rats is low.

OBJECTIVE:
To establish the linear regression equation between body height and combined length of manubrium and mesostenum of sternum measured by CT volume rendering technique (CT-VRT) in southwest Han population.
METHODS:
One hundred and sixty subjects, including 80 males and 80 females were selected from southwest Han population for routine CT-VRT (reconstruction thickness 1 mm) examination. The lengths of both manubrium and mesosternum were recorded, and the combined length of manubrium and mesosternum was equal to the algebraic sum of them. The sex-specific linear regression equations between the combined length of manubrium and mesosternum and the real body height of each subject were deduced.
RESULTS:
The sex-specific simple linear regression equations between the combined length of manubrium and mesostenum (x3) and body height (y) were established (male: y = 135.000+2.118 x3 and female: y = 120.790+2.808 x3). Both equations showed statistical significance (P < 0.05) with a 100% predictive accuracy.
CONCLUSION
CT-VRT is an effective method for measurement of the index of sternum. The combined length of manubrium and mesosternum from CT-VRT can be used for body height estimation in southwest Han population.
