Objective To study the different expressions of receptor activator of nuclear factor-kappa B ligang(RANKL) mRNA in spleens of rats fed with diet of low calcium and high fluoride. Methods A 2× 2×2 factorial design was used and the factors were calcium, fluoride and action time. In the design, 40 Wistar rats [average body mass(118.9±13.5)g] were divided into four groups randomly by weight: control with normal diet (0.790%, calcium), low calcium group with low calcium intake(0.063%, calcium), high fluoride group with normal diet and high fluoride intake(100 mg/L, fluoride) and low calcium and high fluoride group with low calcium and high fluoride intake. After 4 and 8 months, 5 rats of each group were sacrificed and total RNA was extracted from spleen. And the expression levels of RANKL mRNA were determined by reverse transcription polymerase chain reaction (RT-PCR). Results At time of 4 months, the expression level of RANKL mRNA was 0.13± 0.05,0.13± 0.03,0.17±0.02,0.27± 0.05 and at time of 8 months, it was 0.11 ± 0.01,0.16 ± 0.02,0.16± 0.03,0.36 ± 0.07 in control group, low calcium group, high fluoride group, low calcium with high fluoride group, repectively. The factorial design AVONA showed that low calcium and high fluoride had significant effects on RANKL mRNA expression(F = 40.224,56.679, all P < 0.05) while action time had not(F = 2.850, P > 0.05 ). The interactions of low calcium with high fluoride or high fluoride with action time were signifieant(F = 7.247, 18.789, all P < 0.05) while the interaction of high fluoride with action time was not(F = 1.751, P > 0.05). Conclusions Low calcium alone or high fluoride alone or low calcium with high fluoride or low calcium with action time can increase the the RANKL mRNA expression level. High fluoride does not affect the RANKL mRNA level as the action time is prolonged.

This study is to develop an HPLC method for the simultaneous determination of (-)-epicatechin, 5-O-caffeoylshikimic acid, neoisoastilbin, astilbin, neoisoastilbin, isoastilbin and engeletin in Smilacis Glabrae Rhizoma. Samples of Smilacis Glabrae Rhizoma, Heterosmilacis Chinensis Rhizoma and Heterosmilacis Yunnanensis Rhizoma were separated on an Agilent Zorbax SB-C18 column with gradient elution of acetonitrile-0.05% phosphoric acid at a flow rate of 1.0 mL · min(-1). The detected wavelength was set at 230 nm and the column temperature was maintained at 35 °C. The contents of (-)-epicatechin, 5-O-caffeoylshikimic acid, neoastilbin, astilbin, neoisoastilbin, isoastilbin and engeletin in 84 Smilacis Glabrae Rhizoma samples were in the range of trace-1.381, trace-9.913, trace-3.673, 0.6706-27.08, trace-1.181, trace-4.833 and trace-2.754 mg · g(-1), respectively. The established method was used for analysis of common adulterants. The results demonstrated that the contents of (-)-epicatechin in Heterosmilacis Yunnanensis Rhizoma and Heterosmilacis Chinensis Rhizoma were 0.01163-0.06007 mg · g(-1) and 0.01583-0.08585 mg · g(-1), respectively, while the other six constituents were not detected. The method is simple and accurate, and can be used for the quality control of Smilacis Glabrae Rhizoma. The constituents of Heterosmilacis Yunnanensis Rhizoma and Heterosmilacis Chinensis Rhizoma are significantly different from Smilacis Glabrae Rhizoma, and they are not suitable for using as Smilacis Glabrae Rhizoma.
