Effect of Huanshuai Recipe Oral Liquid ([characters: see text]) on renal dysfunction progression in patients with atherosclerotic renal artery stenosis.

OBJECTIVE: To investigate the effect of Huanshuai Recipe Oral Liquid ([characters: see text], HSR) on retarding the progression of renal dysfunction in patients with atherosclerotic renal artery stenosis (ARAS). METHODS: A total of 52 ARAS patients with the Chinese medicine (CM) syndrome of qi deficiency and blood stasis, phlegm and dampness retention were recruited and randomly assigned into the treatment group (36 cases) and the control group (16 cases). Both groups received a basic treatment (high-quality low-protein diet, blood pressure control, lipid-lowering, correcting the acidosis, etc.). In addition, the treatment group received 20 mL HSR and the control group received placebo, 3 times a day for 6 months. Renal function (serum creatinine, blood urea nitrogen and uric acid) and blood lipids (cholesterol, triglycerides and low density lipoprotein) were examined monthly. The estimated glomerular filtration rate (eGFR) and CM syndrome score were compared between groups. RESULTS: After treatment, compared with the control group, the serum creatinine level, uric acid level and CM syndrome score of the treatment group were significantly decreased (P<0.05 or P<0.01), and the eGFR in the treatment group were significantly increased (P<0.05). CONCLUSION: HSR can effectively improve the renal function and clinical symptoms of ARAS patients.

Study on the relationship between blood stasis syndrome and clinical pathology in 227 patients with primary glomerular disease.

OBJECTIVE: To investigate the relationship between the severity of Chinese medicine (CM) blood stasis syndrome (BSS) with clinical features and renal lesion indexes of the primary glomerular disease. METHODS: An epidemiological survey was conducted to collect the data of 227 patients diagnosed as chronic primary glomerular diseases, and their severity of BSS were scored three days before renal biopsies were performed. The following clinical indexes were analyzed: age, course of glomerular diseases, 24-h urine protein ration (Upro), hypertension and blood pressure (BP) progress, serum creatinine levels (Scr), estimation of glomerular filtration rate based on the predigesting equation of MDRD (eGFR), blood urea nitrogen (BUN), uric acid (UA), triglyceride (TG), cholesterol (CHO), haematoglobin (HGB), albumin (ALB), and the correlation among renal pathological types, pathology lesion indexes, and BSS scores. RESULTS: (1) Among the 227 patients, 207 (91.19%) were diagnosed as BSS, in which 95 cases were considered as moderate and the rest 112 cases as severe. (2) There was a negative correlation between age, gender, grades of the hypertension, and the BSS score. Multiple stepwise regression analysis showed that Upro, CHO, TG, and eGFR were positively related to the BSS score (P<0.05). (3) The BSS score has a positive correlation with indexes of chronic renal pathology, especially the tubular atrophy and interstitial fibrosis. The severity of proliferation and glomerular sclerosis was accompanied with higher BSS scores with a significant difference (P<0.05). CONCLUSIONS: BSS is one of the most common CM syndromes among patients with the primary glomerular diseases; the BSS score has a positive correlation with Upro, CHO, TG, eGFR, as well as the index of chronic renal pathology. Based on these observations, the BSS may be used as an indicator of the development of renal diseases. Being positively diagnosed as BSS could indicate the beginning of the chronic phase of the primary glomerular diseases.

Synthesis and discovery of autophagy inducers for A549 and H460 lung cancer cells, novel 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives.

A series of novel 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives were synthesized, and the effects of the compounds on A549 cell growth were investigated. The results showed that all of the 1-(2'-hydroxy-3'-aroxypropyl)-3-aryl-1H-pyrazole-5-carbohydrazide derivatives 2 could inhibit the growth of A549 cells in dosage- and time-dependent manners. Typically, compound 2a and 2d induced A549 cells to autophagy but did not cause apoptosis and necrosis in the cells, and 2d had the most autophagy inducing effect in H460 cells. More importantly, 2a and 2d did not inhibit the growth of HUVEC cells.
