OBJECTIVE: To optimize the water extraction technology of Bupi yangshen granules, and to provide basis for the follow-up research and development of it. METHODS: The contents of astragaloside Ⅳ and salvianolic acid B in water extract of Bupi yangshen granules, were determined by HPLC-ELSD and HPLC-DAD. Using the comprehensive score of contents of astragaloside Ⅳ and salvianolic acid B and extract yield as index, weight coefficient of indicators were determined by AHP, CRITIC and AHP-CRITIC mixed weighting method. L9(34) orthogonal test was used to optimize decoction time, water volume and decoction times in water extraction technology of Bupi yangshen granules. Validation test was also performed. RESULTS: The weight coefficient determined by AHP-CRITIC mixed weighting method was the most reasonable. The optimal extraction technology was decocting twice, adding 12-fold water, 1 h each time. The results of 3 times of validation test showed that the average contents of astragaloside Ⅳ and salvianolic acid B were 8.79, 609.50 mg (total amount of 121 g medicinal herbs extracted from whole prescription), respectively. The average extract yield was 31.24%. Average comprehensive score was 96.59(RSD=1.01%,n=3). CONCLUSIONS: The optimized water extraction technology is reproducible, stable and feasible. It can provide a scientific basis for the follow-up development and industrial production of Bupi yangshen granules.

OBJECTIVE: To establish the method for the content determination of astragaloside Ⅳ, emodin and chrysophanol in Jianpi yishen pills (JYP) and to investigate the effects of JYP on calcium, phosphorus metabolism and inflammatory factors in chronic renal failure (CRF) model rats. METHODS: HPLC method was adopted. The determination of astragaloside Ⅳ, emodin and chrysophanol was perform on Agilent Zorbax SB-C18, Agilent TC C18 column, respectively; mobile phase consisted of acetonitrile-water (36 ∶ 64, V/V) and methanol-0.1% phosphoric acid solution (75 ∶ 25, V/V); the detectors were evaporative light-scattering detector and diode-array detector (detection wavelength of 254 nm); the column temperatures were set at 30 ℃and 25 ℃ at the flow rate of 1.0 mL/min; the sample sizes were 20 and 10 μL. SD rats were randomly divided into normal group, model group, Niaoduqing group (1.80 g/kg) and JYP low-dose, medium-dose and high-dose groups (1.71, 3.43, 6.85 g/kg), with 10 rats in each group. Except for normal group, CRF model of other groups were established by 5/6 nephrectomy in other groups. Four months after modeling, normal group and model group were given constant volume of water intragastrically; admi- nistration groups were given relevant medicine intragastrically, once a day, for consecutive 12 weeks. The levels of serum creatinine (Scr), urea nitrogen (BUN), parathyroid hormone (PTH) and inflammatory factors (IL-6, TNF-α) were measured by ELISA. Methyl thymol blue colorimetric method and phosphomolybdic acid method were used to detect the contents of blood calcium and phosphorus. Correlation of inflammatory factors with related calcium and phosphorus metabolism indexes (blood calcium, blood phosphorus, PTH) were investigated with Pearson assay. RESULTS: The linear range of astragaloside Ⅳ, emodin and chrysophanol were 54.537-381.759, 2.960-20.720, 6.318-44.223 μg/mL, respectively. The limits of quantitation were 0.010, 0.288, 0.216 μg/mL; the limits of detection were 0.003, 0.096, 0.072 μg/mL. RSDs of precision, reproducibility and stability tests were all lower than 3.0%. The recoveries were 97.18%-102.33%(RSD<3%,n=9). After modeling (before medication), serum contents of Scr and BUN in model group and administration group were increased significantly, compared with normal group (P<0.01). After medication, above indexes of administration group were decreased significantly, compared with model group and the same group before medication (P<0.01). Compared with normal group, the content of blood calcium were decreased significantly, while the contents of IL-6 and TNF-α were increased significantly (P<0.01). Compared with model group, the content of blood calcium were increased significantly in JYP medium-dose and high-dose groups, while serum content of PTH in Niaoduqing group, serum contents of PTH and IL-6 in JYP medium-dose and high-dose groups as well as serum content of TNF-α in administration group were decreased significantly (P<0.05 or P<0.01). JYP had no significant effect on blood phosphorus in rats, and there was no correlation of inflammatory factors with related calcium and phosphorus metabolism indexes (P>0.05). CONCLUSIONS: The established content determination method is simple, specific and sensitive, and can be used for content determination of astragaloside Ⅳ, emodin and chrysophanol in JYP. JYP can improve renal function of CRF model rats, relieve calcium metabolism disorder and inhibit the expression of inflammatory factors.

Objectives Explore the experiences of professor Li Shunmin in treating chronic kidney diseases (CKD) according to spleen and kidney theory.Methods Information of medical records was acquired from Shenzhen TCM hospital information management department. It included the records from Jan, 2014 to Mar, 2016. Access database was established and SQL was used for data processing. Cytoscape 2.8 software was used to visualize the results and analyze the treatment characteristics in CKD.Results ProfessorLi used herbs of nourishing spleen and kidney to treat CKD. The herbs included Astragalus membranaceus, Rhizoma Dioscoreae, Rehmannia glutinosa and Gordon Euryale. The rules of treatment included invigorating spleen and kidney, and regulating liver and lung. The characteristics of using herbs included combination of cooling and warming herbs, bitter and pungent herbs, and sweet herbs for CKD.Conclusions Data mining could help to discover the rules of Li Shunmin in treating CKD. The results confirmed the academic attitude of treating CKD on spleen and kidney. It provided ideas and direction for CKD treatment.

Objective To investigate the characteristics of traditional Chinese medical syndromes and syndrome patterns in diabetic nephropathy (DN) from delta regions of pearl river. Methods A cross-section and retrospective trial was carried out in 292 DN inpatients from four hospitals(the First Affiliated Hospital of Guangzhou University of TCM, Foshan Hospital of TCM, Shenzhen Hospital of TCM, and Zhongshan Hospital of TCM) from January, 2003 to December, 2005. Demographic information, past history, symptoms and laboratory parameters of the patients were collected.Results Of the enrolled 292 patients, there were 14 in the clinical stage Ⅱ, 42 in stage Ⅲ, 210 in stage Ⅳ, and 26 in stage Ⅴ. The manifestations of TCM syndrome were dominated as lassitude and weakness (69.9%), loss of energy (54.1%), dry mouth (49.3%), aching waist (42%), dry mouth and throat (38%), numbness of extremities (69.9%), dry eyes (33.2%) and dry stool (31.5%), but the signs of frequent sighing, night sweating and tidal fever were less found. For the deficiency syndrome patterns, there existed deficiency of kidney (37.7%), spleen (27.7%), heart (8.9%), liver (3.8%) and lung (2.1%) when differentiating the syndromes according the five zang-organs; there was deficiency of yin (32.5%), Qi (19.5%), blood (9.6%) and yang (8.2%) when differentiating the syndromes according to Qi, blood, yin and yang; there were complex deficiency syndromes such as deficiency of Qi and yin (40.4%), deficiency of spleen and kidney Qi (26.4%), deficiency of lung and kidney Qi(4.8%) and deficiency of yin and yang (3.8%). For the excess syndrome patterns, there were blood stasis syndrome (49.7%), damp-heat syndrome (33.2%), water-dampness syndrome (25%), and Qi stagnation syndrome (7.5%). Conclusion The syndrome patterns of DN present the following characteristics: leading deficiency syndromes being kidney deficiency and spleen deficiency when differentiating the syndromes according the five zang-organs, being yin deficiency and Qi deficiency when differentiating the syndromes according to Qi, blood, yin and yang, and complex deficiency syndromes being Qi-yin deficiency and spleen-kidney Qi deficiency. The leading excess syndromes are blood stasis syndrome and damp-heat syndrome. The manifestations of DN are characterized by the concurrence of deficiency and excess, cold and heat. The pathogenesis of DN is classified into deficiency in the root and excess in the branch. The deficiency syndrome mainly involves Qi and yin, and is located in spleen and kidney. The excess syndrome is characterized by blood stasis and damp-heat, and by water-dampness and dampness-turbidity in the late stage of DN. In one word, the pathogenesis of DN is characterized by deficiency of Qi and yin, and blood-stasis blocking kidney collaterals.
