OBJECTIVETo establish an HPLC method for the simultaneous determination of three major bioactive components in Jingzhi Guizhi Fuling capsules namely laetrile, paeoniflorin and paeonol.
METHODA LiChrospher C18 column (4.6 mm x 250 mm, 5 microm) was used. The chromatography was carried out with a stepwise gradient programming. The mobile phase was acetonitrile-water (containing 0.1% phosphorous acid) and the flow rate was 1.0 mL x min.
RESULTThe linear range of laetrile was 12.87-102.94 micron x mL(-1), r = 0.999 9, paeoniflorin 24.84 - 198.7 microg x mL(-1), r = 0.9999 and paeonol 12.57-100.56 microg x mL(-1), r = 0.999 9. The method is accurate with variation less than 1.5 % and recovery more than 95 %.
CONCLUSIONThe method was successfully applied to analyze three major bioactive components in Jingzhi Guizhi Fuling capsules.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

OBJECTIVE:
To prove the feasibility of detecting menstrual blood as well as its cellular localization with rabbit-anti-human matrix metalloproteinase-11 (MMP-11) polyclonal antibody.
METHODS:
MMP-11 in menstrual blood, peripheral blood, vaginal liquid, aged menstrual bloodstain, and endometrium sections were assayed with SAP immunohistochemistry.
RESULTS:
MMP-11 was found only in menstrual samples within stroma and epithelium cells.
CONCLUSION
MMP-11 polyclonal antibody may be applied in the distinction between menstrual blood and venous blood.

OBJECTIVETo observe the effect of Spleen-invigorating Prescription (SIP) on dendritic cell function in patients with chronic hepatitis B.
METHODSA total of 60 patients with chronic HBV of Pi-deficiency syndrome type were enrolled and randomized to 2 groups, 30 in each group. Patients in the control group were given intramuscular injection with human interferon alpha 1b, 3 times a week, while those in the treated group were given orally with SIP twice a day, the therapy lasted for 6 months. Dendritic cells (DCs) were isolated from peripheral blood and cultured, then the expression of surface markers, HLA-DR, CD86, CD80, CD40, CD14 and CD11c were detected before and after treatment by flow cytometry, and the function of DCs was also evaluated by mixed lymphocyte reaction (MLR) determination once before treatment and once after treatment.
RESULTSThe expressions of DCs' surface CD86, CD80, CD40 and CD11c in the treated group were higher (P < 0.05, P < 0.01) and the changes of stimulating index, IFN-gamma and IL-12 were superior in the treated group to those in the control group (P < 0.05).
CONCLUSIONSSIP can significantly improve DC's function, so, one of mechanisms of SIP in improving clinical efficacy may be the regulation of immune function.
