OBJECTIVETo systematically review the efficacy and safety of sodium ferulate (SF) for the treatment of diabetic nephropathy.

METHODSBy computerized retrieving the Cochrane Library, MEDLINE, EMBASE, CNKI, VIP, CBM (theses, conference and internet materials), as well as data from internet materials regarding randomized controlled clinical trials of sodium ferulate for the treatment of diabetic nephropathy were collected completely. Data were strictly extracted using the simple evaluation method recommended in Cochrane Handbook and Meta-analysis was performed using Revman 5.0 software.

RESULTSFourteen randomized controlled trials involving 906 patients met the inclusion criteria. Meta-analysis showed that as compared with the control group, the effects in SF group were superior in terms of reducing urinary albumin excretion rate (UAER) at early stage [WMD = 16.08, 95% confidence interval (95% CI): 11.01 to 21.15] and clinical stage (WMD = 82.66, 95% CI: 66.95 to 98.37), urinary endothelin/endothelin-1 (ET/ET-1, WMD = 10.78, 95% CI: 8.18 to 13.39), levels of serum creatinine (SCr, WMD = 6.42, 95% CI: 1.83 to 11.01), blood urea nitrogen (BUN, SMD = 1.45, 95% CI: 0.19 to 2.71) and total cholesterol (TC, WMD = 0.84, 95% CI: 0.56 to 1.21, as well as in increasing high density lipoprotein-cholesterol (HDL-C, WMD = 0.17, 95% CI: 0.09 to 0.26), showing significant difference between groups. However, the effects of SF were insignificantly different to those of control in reducing fasting blood glucose (FBG, WMD = 0.17, 95% CI: -0.03 to 0.37) and triglyceride (TG, SMD = -0.13, 95% CI -0.49 to 0.23).

CONCLUSIONSAt present the evidences show that SF is superior to the conventional treatment in reducing UAER, ET, SCr, BUN, TC and increasing HDL-C, but there is no evidence to show that SF is superior in reducing FBG and TG. However, the evidence is not strong enough due to the low quality of included literature. More large-scale, multi-center, randomized trials are needed to confirm the efficacy and safety of SF in treating diabetic nephropathy.

Compared with herbal drugs, medicine processed from animals (animal medicine) was thought to have more bioactive substances and higher activities. Biotransformation effect often plays an important role in their effect. However, researches about effect of animal medicine on diabetic nephropathy and applying animal medicine as natural bio-transformer were seldom reported. The purpose of this paper was to reveal the use of Bombyx Mori L. on diabetic nephropathy from ancient to modern times. The classical literature indicated that Saosi Decoction (), which contains Bombyx Mori L. or silkworm cocoon, was applied to treat disorders congruent with modern disease diabetic nephropathy from the Ming to Qing Dynasty in ancient China. Modern studies showed that Bombyx Mori L. contains four main active constituents. Among these, 1-deoxynojirimycin (1-DNJ) and quercetin showed promising potential to be new agents in diabetic nephropathy treatment. The concentrations of 1-DNJ and the activities of quercetin in Bombyx Mori L. are higher than in mulberry leaves, because of the biotransformation in the Bombyx Mori L. body. However, these specifific components need further human and mechanistic studies to determine their therapeutic potential for this challenging condition.

Diabetic nephropathy is one of the main causes of renal end-stage disease. The pathogenesis of diabetic nephropathy is complex. The current treatment is only for a particular cause without multi-target therapeutic drugs. Chinese medicine is a great treasure with multi-component complex drugs interacting with multiple targets and functions. This paper reviewed the protective effect of Chinese medicine for treating diabetic nephropathy in clinical studies, in vivo studies, and in vitro studies. The possible mechanisms, the major compounds and active crude drugs were also summarized. It was shown that Chinese medicine could not only relieve several symptoms and improve the quality of life, but also reduce the levels of proteinuria and kidney damage, and further improve renal function via multiple pathways based on the whole human system. Moreover, there were no reports of severe adverse reactions during the treatment.

Along with the development of clinical and pathological studies, and the wide spreading of the concepts or ideas of chronic kidney disease (CKD) and diabetic kidney disease (DKD), the clinical research of DKD has entered a new stage, which has brought new requirements for Chinese medicine treatment of DKD. It is necessary to carry out good design, have reasonable inclusion and exclusion criteria, select appropriate biomarkers capable of reflecting the pathophysiology of DKD, choose convincible hard endpoints capable of reflecting the prognosis of DKD, and conduct observations of enough long therapeutic course. This is the main trend of conducting clinical trials of DKD and scientifically assessing the efficacy of Chinese medicine treatment of DKD.

This study explored the in vivo effects and mechanisms of the modern classical prescription Supplemented Gegen Qinlian Decoction Formula(SGDF) against diabetic kidney disease(DKD). Sixty rats were randomly divided into the normal group, model group, SGDF group, and rosiglitazone(ROS) group. The modified DKD rat model was established by employing the following three methods: exposure to high-fat diet, unilateral nephrectomy, and intraperitoneal injection of streptozotocin(STZ). After modeling, rats in the four groups were treated with double distilled water, SGDF suspension, and ROS suspension, respectively, by gavage every day. At the end of the 6 th week of drug administration, all the rats were sacrificed for collecting urine, blood, and kidney tissue, followed by the examination of rat general conditions, urine and blood biochemical indicators, glomerulosclerosis-related indicators, podocyte pyroptosis markers, insulin resistance(IR)-related indicators, and key molecules in the insulin receptor substrate(IRS) 1/phosphatidylinositol-3-kinase(PI3 K)/serine threonine kinase(Akt) signaling pathway. The results showed that SGDF and ROS improved the general conditions, some renal function indicators and glomerulosclerosis of DKD model rats without affecting the blood glucose(BG). Besides, they ameliorated the expression characteristics and levels of podocyte pyroptosis markers, alleviated IR, and up-regulated the protein expression levels of the key molecules in IRS1/PI3 K/Akt pathway to varying degrees. In conclusion, similar to ROS, SGDF relieves DKD by targeting multiple targets in vivo. Specifically, it exerts the therapeutic effects by alleviating podocyte pyroptosis and IR. This study has preliminarily provided the pharmacological evidence for the research and development of new drugs for the treatment of DKD based on SGDF.
