To investigate the protective effect of Yiqi Huoxue decoction on the kidney in diabetic goto-Kaizaki (GK) rats. Eight Wistar rats were used as normal control group. According to body weight and blood glucose, 16 GK rats were randomly divided into model control group and Yiqi Huoxue group, with 8 rats in each group. Drugs were administrated for 6 weeks. The rats were weighed and fasting blood glucose (FBG) were measured weekly; the glycosylated hemoglobin (HbALc) and 24 h metabolic rate were measured at the end of third and sixth weeks, at the same time, urine was collected to measure urinary glucose (U-GLU), urinary creatinine (U-CREA) and total proteinuria (U-TP) by biochemical method and calculate 24 h protein excretion rate (UAER). At the end of treatment, rats were sacrificed in anesthesia, and creatinin (CREA), uric acid (UA) and cholesterol (CHOL) were detected by biochemical method and glutathione peroxidase (GSH-Px) was detected by manual method with the blood drawn from heart. Both kidneys were taken and weighed to calculate the renal hypertrophy index. The kidneys were placed into neutral formalin and observed under light microscope for pathological change after Periodic Acid-Schiff (PAS) staining. The results showed that as compared with the normal control group, FBG, HbALc, 24 h Metabolic rate, U-GLU, UAER, serum CREA, UA and CHOL levels, as well as renal hypertrophy index were significantly increased (<0.05) in the model group, while the body weight growth rate, serum GSH-Px level were significantly reduced(<0.05); in addition, renal glomerular injury and structural changes were observed in the model group. As compared with the model group, serum GSH-Px level was significantly increased (<0.05) in the Yiqi Huoxue group, While FBG, HbALc, 24 h Metabolic rate, U-GLU, UAER, serum CREA, UA and CHOL levels, as well as renal hypertrophy index were significantly reduced (<0.05); meanwhile, renal glomerular injury and structural changes were improved in the Yiqi Huoxue group. The results showed that Yiqi Huoxue decoction can significantly increase serum GSH-Px level, reduce FBG, HbALc, 24 h metabolic rate, U-GLU, UAER, serum CREA, UA and CHOL levels, as well as renal hypertrophy index, and improve renal pathology in diabetic GK rats.

Both Patrinia Herba and Patrinia Radix are traditional Chinese herbal medicines. The herbal source and medicinal part of them are confusing in the herbal medicine market of China. To explore the evolution and transition of the herbal source and medicinal part of Patrinia Herba and Patrinia Radix, this paper systematically summarizes the record of the herbal source and medicinal part of them in ancient classics of herbal medicine in China. According to the findings, before Ming Dynasty, Patrinia Herba originated from the radix of the plants with yellow flowers of Patrinia. In Ming and Qing Dynasty, Patrinia Herba originates from the whole plant (including the radix)of the plant with white flowers of Patrinia. In Ming Dynasty, Patrinia Radix, stemming from the radix of the plants with yellow flowers of Patrinia, started to be used as a traditional Chinese herbal medicine, which had the same herbal source with that of Patrinia Herba before Ming Dynasty. Therefore, Patrinia Herba and Patrinia Radix can be seen as the same traditional Chinese herbal medicine, and the genuine of Patrinia Herba should be the radix and the whole herba of P. scabiosaefolia and P. heterophylla.

Background: With the increase of troops entering the plateau for a variety of missions, the occurrence of de-adaptation increased significantly when the army returned to the plains, however, until now, there has been no effective treatment for de-adaptation to high altitude. Objective: To observe the interventional effects of compound Chinese herbal preparations (Sankang Capsule, Rhodiola Rosea Capsule and Shenqi Pollen Capsule) on de-adaptation to high altitude, and provide scientific evidence for appropriate treatment methods in the army health care for future missions. Design, setting, participants and interventions: A randomized, single-blind, placebo-controlled trial design was used. Soldiers of a returning army unit who exhibited de-adaptation response symptoms were selected for observation after participating in earthquake relief at high altitude. A total of 543 soldiers were divided into a Sankang Capsule group, a Rhodiola Rosea Capsule group, a Shenqi Pollen Capsule group and a placebo group for drug intervention and administered with corresponding drugs. The course of treatment was 15 days. A self-evaluation scale for de-adaptation to high altitude was used to measure the signs and symptoms exhibited by the soldiers. Main outcome measures: Effective rate of signs and symptoms of de-adaptation to high altitude was analyzed after a 15-day treatment and the differences of improvement rate of symptoms between groups were compared to evaluate the efficacy of the drugs. Results: All three drugs improved the symptoms of de-adaptation to high altitude. Compared with the placebo group, symptoms of de-adaptation to high altitude in the drug-treated groups were remitted (P<0.05). Compared with placebo, Sankang Capsule mainly had well-marked effects on dizziness, fatigue, palpitations, cough, sputum and sore throat (P<0.05); Rhodiola Rosea Capsule significantly reduced the symptoms of fatigue, drowsiness, chest tightness, palpitations, vertigo, lack of attention and memory loss (P<0.05); Shenqi Pollen Capsule significantly reduced the symptoms of dizziness, fatigue, weakness, chest tightness, palpitations, cough, sputum, sore throat, memory loss, unresponsiveness and limb numbness (P<0.05). The symptom improvement rate of Shenqi Pollen Capsule was significantly higher than those of the other two drugs. Conclusion: All the three drugs played an evident role in ameliorating symptoms of de-adaptation, and the use of Shenqi Pollen Capsule was more effective than Rhodiola Rosea Capsule and Sankang Capsule.
