Clinical Efficacy of Xiaoer Anorexia Granule Combined with Saccharomyces Brassicus in Treatment of Pediatric Anorexia and Its Effect on Serum Cytokines / 中国实验方剂学杂志

Objective: To investigate the clinical efficacy of Xiaoer anorexia granule combined with Saccharomyces brassicus in the treatment of infantile anorexia and its effect on serum cytokines. Method: Totally 240 cases of infantile anorexia treated in Jinhua People's Hospital from October 2015 to October 2017 were randomly divided into three groups. Group A (combination group) orally took Xiaoer anorexia granule, 1 pack/time for 1-3 years old, 2 packs/time for 4-6 years old, 3 times a day, and combined with saccharomyces brasiliensis, 0.5 g/time, 2 times a day, 15-30 min before meal. Group B took saccharomyces brasiliensis by the same method as the combination group. Group C took Xiaoer anorexia granules by the same method as above,with 80 cases in each group. 8 weeks is a course of treatment. Serum inflammatory cytokines leptin, SP and Ghrelin were also detected. The clinical efficacy, body weight, height improvement and serum cytokine levels were observed in 3 groups. Result: The total improvement rate of group A was 91.25%, which was significantly higher than 71.25%of group B and 73.75%of group C, with statistically significant differences (PPPPPPPConclusion: Treatment of infantile anorexia with Xiaoer anorexia granules combined with Saccharomyces cerevisiae can improve the total clinical effective rate, adjust serum cytokine levels and increase height and body mass.

Evaluation of microwave-assisted extraction for aristolochic acid from Aristolochiae Fructus by chromatographic analysis coupled with nephrotoxicity studies.

In this paper, a microwave-assisted extraction (MAE) method was established for aristolochic acid-I from Aristolochiae Fructus, and the advantage of MAE was evaluated by chromatographic analysis coupled with nephrotoxicity studies. The experimental parameters of MAE for aristolochic acid-I in Aristolochiae Fructus were investigated and MAE was compared with Soxhlet extraction and ultrasound-assisted extraction in terms of extraction yields and extraction conditions. Under the optimum conditions, MAE could provide higher extraction yields of aristolochic acid-I (1.10 mg/g) than ultrasound-assisted extraction (0.82 mg/g) and Soxhlet extraction (0.95 mg/g), in addition to using less solvent and having a shorter extraction time. Furthermore, the nephrotoxicities of the extracts of Aristolochiae Fructus from different extraction procedures were investigated in Sprague-Dawley rats. The results of nephrotoxicity studies of, for example, general conditions, biochemistry parameters and histopathology examination showed no significantly differences in the nephrotoxicity levels of the extracts from MAE and that from Soxhlet extraction. These results indicated that MAE technique is a simple, rapid and effective extraction method, and the microwave irradiation during MAE procedure did not have any influence on the nephrotoxicity of Aristolochiae Fructus compared with Soxhlet extraction.

Optic properties of bile liquid crystals in human body.

AIM:To further study the properties of bile liquid crystals, and probe into the relationship between bile liquid crystals and gallbladder stone formation, and provide evidence for the prevention and treatment of cholecystolithiasis.METHODS:The optic properties of bile liquid crystals in human body were determined by the method of crystal optics under polarizing microscope with plane polarized light and perpendicular polarized light.RESULTS:Under a polarizing microscope with plane polarized light, bile liquid crystals scattered in bile appeared round, oval or irregularly round. The color of bile liquid crystals was a little lighter than that of the bile around. When the stage was turned round, the color of bile liquid crystals or the darkness and lightness of the color did not change obviously. On the border between bile liquid crystals and the bile around, brighter Becke-Line could be observed. When the microscope tube is lifted, Becke-Line moved inward, and when lowered, Becke-Line moved outward. Under a perpendicular polarized light, bile liquid crystals showd some special interference patterns, called Malta cross. When the stage was turning round at an angle of 360(o), the Malta cross showed four times of extinction. In the vibrating direction of 45(o) angle of relative to upper and lower polarizing plate, gypsum test-board with optical path difference of 530nm was inserted, the first and the third quadrants of Malta cross appeared to be blue, and the second and the fourth quadrants appeared orange. When mica test-board with optical path difference of 147nm was inserted, the first and the third quadrants of Malta cross appeared yellow, and the second and the fourth quadrants appeared dark grey.CONCLUSION:The bile liquid crystals were distributed in bile in the form of global grains. Their polychroism and absorption were slight, but the edge and Becke-Line were very clear. Its refractive index was larger than that of the bile. These liquid crystals were uniaxial positive crystals. The interference colors were the first order grey-white. The double refractive index of the liquid crystals was n = 0.011-0.015.
