OBJECTIVEThe purpose of this review is to discuss some critical issues of isoflavones protective against the development of prostate cancer (PCa).

DATA SOURCESData cited in this review were obtained primarily from PubMed and Embase from 1975 to 2015.

STUDY SELECTIONArticles were selected with the search terms "isoflavone", "Phytoestrogen", "soy", "genistin", and "PCa ".

RESULTSIsoflavones do not play an important role on prostate-specific antigen levels reduction in PCa patients or healthy men. The effect of isoflavones on sex hormone levels and PCa risk may be determined by equol converting bacteria in the intestine, specific polymorphic variation and concentrations of isoflavones. The intake of various types of phytoestrogens with lower concentrations in the daily diet may produce synergistic effects against PCa. Moreover, prostate tissue may concentrate isoflavones to potentially anti-carcinogenic levels. In addition, it is noteworthy that isoflavones may act as an agonist in PCa.

CONCLUSIONSIsoflavones play a protective role against the development of PCa. However, careful consideration should be given when isoflavones are used in the prevention and treatment of PCa.

Puerarin injection is commonly used in clinical treatment of coronary heart disease, angina pectoris, retinal artery, vein occlusion, sudden deafness and so on. This paper is aimed to evaluate the safety of puerarin injection in clinical use and explore the related factors that may cause its adverse reactions (ADRs), so as to find the warning signal of safety medication in time, put forward early warning, make early judgment and treatment, and ensure the safety of drug use. By strengthening surveillance, the best medication plan was established to prevent the occurrence of adverse reactions of puerarin injection and enhance people's awareness on the safety of puerarin injection. Database were searched to collect literature related to ADRs of puerarin injection. The data were extracted and analyzed by decision tree with treeage software and ² test was used to verify the data. A total of 62 papers involving 129 cases were included. The results showed that ADRs occurred mostly in patients aged 50-79 years, with the immune system and blood system accounting for the majority (88.3%), and ADRs occurred mostly 48 h after drug administration (61.1%). The severity of ADRs was not related to the dosage of puerarin, but it was related to the choice of the infusion solvent. In puerarin injection, most of the ADRs were moderate or severe (64.3%), 13 out of 129 cases were of death. Therefore, the indications and methods of use should be strictly controlled, and the allergic history of patients should be carefully questioned before medication to strengthen the monitoring of drug use.

OBJECTIVETo study the antagonistic effect of 3'-daidzein sulfonate sodium (DSS) on benign prostatic hyperplasia (BPH) and its possible mechanism.

METHODSForty healthy mice were randomly divided into five groups: a normal control group without any treatment, a model group of BPH treated by subcutaneous injection of testosterone propionate, a positive control group with the BPH procedure treated by Qianliekang, a 20 mg/(kg x d) DSS group with the BPH procedure and a 40 mg/(kg x d) DSS group with the BPH procedure. After 12 days of the above treatments, the mice were sacrificed for measurement of the prostate glandular wet weight, the index of prostate gland (PI), the morphological changes of prostate gland by light microscopy and the contents of testosterone and estradiol in the serum.

RESULTSThe prostate wet weight and PI decreased dose-dependently after DSS treatment for 12 days compared with the BPH model group (P < 0.05 or P < 0.01). The hyperplastic epithelioglandular papilla waned and even disappeared in the DSS treated groups under the light microscope, the epithelial cells became cubical or flat. The effect of DSS at 40 mg/(kg x d) was similar to that of the positive anti-BPH drug Qianliekang. DSS reduced the serum testosterone, estradiol contents and the T/E2 ratio (P < 0.05 or P < 0.01).

CONCLUSIONDSS has significant antagonistic effect on BPH induced by testosterone propionate in mice, which may involve its regulatory action on the sex hormone balance.

OBJECTIVETo explore the effect of puerarin in improving the insulin resistance (IR) and its closely related abnormal lipid and fibrinolytic activity in patients with coronary heart disease (CHD).

METHODSSeventy-six patients with CHD were randomly divided into two groups, 40 in the puerarin group and 36 in the routine treated group. Puerarin 500 mg was given to the former in addition to routine therapy by adding to 250 ml of normal saline for intravenous dripping once a day with a therapeutic course of 3 weeks. The changes of fasting blood glucose (FBG), fasting plasma insulin (FINS), plasma total cholesterol (TC), triglyceride (TG), low and high density lipoprotein cholesterol (LDL-C & HDL-C) and plasminogen activator inhibitor-1 (PAI-1) activity were measured before and after treatment, and the insulin sensitivity index (ISI) calculated. At the same time, tissue plasminogen activator (tPA) activity before and during venous occlusion test (VOT) was tested. Besides, 30 healthy subjects were taken as control.

RESULTSIn CHD patients, FINS, TC, TG, LDL-C and PAI-1 levels were higher and ISI, HDL-C and tPA before and during VOT were lower than those in the healthy controls. FINS and ISI correlated well with lipids and fibrinolytic abnormality. After puerarin treatment, FINS level lowered and ISI increased significantly (P < 0.01), while comparing with the routine group, TC, TG, LDL-C and PAI-1 were lower but HDL-C and tPA activity before and during VOT were higher in the puerarin group (P < 0.05, P < 0.01). Correlation analysis showed that FINS was positively correlated with TC, TG, LDL-C and PAI-1 and negatively correlated with HDL-C, tPA before and during VOT; ISI was negatively correlated with TC, TG, LDL-C and PAI-1 and positively correlated with HDL-C and tPA before and during VOT in the puerarin group.

CONCLUSIONPuerarin could improve the IR, IR related lipid and fibrinolytic activity abnormality in CHD patients.

OBJECTIVE: To observe the effect and mechanism of avandia and puerarin used in combination for diabetic nephropathy. METHODS: A total of 180 patients with diabetic nephropathy were randomly divided into 3 groups. The control group (58 patients, group A) were treated with routine therapy including controlling the blood glucose and blood pressure, while 60 patients in group B were treated by avandia besides routine treatment of the control group. Anoter 62 cases in group C were administered with puerarin combined with avandia for 12 weeks. The indexes such as urea nitrogen, serum creatinine, triglyceride, cholesterol, low density lipoprotein, high density lipoprotein, mean arterial pressure, fasting blood glucose, 2h plasma glucose, glycosylated hemoglobin, and 24 h urinary albumin excretion rate were tested before and after the treatment . RESULTS: No significant differences were found in the indexes such as triglyceride, serum cholesterol, low density lipoprotein, high density lipoprotein, glycosylated hemoglobin, malonaldehyde, erythrocuprein, blood urea nitrogen, serum creatinine and 24 h urinary albumin excretion rate among the 3 groups (P>0.05). There were no significant differences in all indexes before and after the treatment in group A (P>0.05) . After the treatment, 24 h urinary albumin excretion, urea nitrogen, serum creatinine, mean arterial pressure, fasting blood glucose, 2 h plasma glucose, glycosylated hemoglobin, triglyceride, serum cholesterol, low density lipoprotein decreased significant (P<0 05) while high density lipoprotein increased significant (P<0.05). CONCLUSION Avandia has better effect on adjusting the blood lipid and decreasing the urinary albumin excretion rate. Puerarin combined with avandia is more effective for improving the renal function and remission of islet function than using avandia alone. Puerarin and avandia have significant synergism.

OBJECTIVETo investigate the myocardial protective effect of puerarin injection (PI) in children with severe pneumonia.

METHODSOne hundred children with pneumonia enrolled were divided into two groups according to their condition of illness. Forty-eight children of mild condition in the common group (CG) were treated with conventional treatment and 52 children of serious condition in the severe group (SG) were treated with conventional treatment with additional PI or fructose-1,6-disphosphate (FDP) for myocardial protection. The parameters of serum myocardial zymogram, ECG and cardiac blood flow were measured and the effects of PI and FDP in patients of serious condition were compared.

RESULTSChange of serum myocardial zymographic parameters was indirectly proportional to the severity of childrens condition. The reduction of myocardial contractive function was demonstrated by the change of cardiac blood flow parameters in Ultrasound Doppler examination (P < 0.01). Both PI and FDP had the effect in protecting myocardium and improving heart function, showing insignificant difference between their efficacy (P > 0.05), but PI had less stimulation to vessels and without any obvious adverse reaction.

CONCLUSIONSevere pneumonia in children can lead to myocardial damage and heart failure, and early applying of myocardial protective measure can significantly improve the prognosis of patient. Myocardial zymographic parameters, especially the CK-MB, are sensitive and important indexes for detecting myocardial injury. PI has effects in protecting myocardium and improving heart function, and therefore, is suitable for spreading and applying in clinical practice.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

OBJECTIVETo investigate the effect of Bushengzhuyang Fang (Yangjing Capsule, YJC) on penile erectile function and its action mechanisms in rats.

METHODSFifty-six male SD rats were randomly divided into seven groups of equal number: blank control, daidzein, daidzein + testosterone, daidzein + sildenafil, daidzein + low-dose YJC, daidzein + medium-dose YJC, and daidzein + high-dose YJC. The rats in the blank control group were treated intragastrically with normal saline and those in the other groups with daidzein at the dose of 100 mg per kg per day for 30 days. Then the last five groups received additionally testosterone (4 mg per kg per day), sildenafil (2.5 mg per kg per day), low-dose YJC, (0.315 mg per kg per day), medium-dose YJC (0.63 mg per kg per day), and high-dose YJC (1. 26 mg per kg per day), respectively. At 0, 30 and 60 days of treatment, we observed the apomorphine-induced spontaneous erectile response and pathological changes in the corpus cavernosum of the rats, recorded the number of penile erection and erectile incubation period, and determined the serum levels of testosterone (T) and luteinizing hormone (LH).

RESULTSAt 30 days of treatment, the number of apomorphine-induced erections was decreased, the erectile incubation period prolonged, and the serum levels of T and LH reduced remarkably in all groups of rats (P < 0.05). Compared with the findings at 30 days, the number of penile erections was significantly decreased at 60 days in the daidzein group (1.39 ± 0.42 vs 2.67 ± 0.33, P < 0.05) and daidzein + low-dose YJC group (1.33 ± 0.49 vs 2.83 ± 0.61, P < 0.05); the erectile incubation period was markedly ex- tended ([16.33 ± 3.11] vs [8.50 ± 0.93] min and [15.50 ± 3.21] vs [8.63 ± 1.54] min, P < 0.05); and the serum levels of T ([5.34 ± 0.89] vs [1.24 ± 0.30] ng/ml and [5.28 ± 1.12] vs [2.07 ± 0.76] ng/ml, P < 0.05) and LH ([3.62 ± 0.37] vs [2.09 ± 0.12] ng/ml and [3.79 ± 0.28] vs [2.17 ± 0.33] ng/ml, P < 0.05) were significantly reduced in the daidzein and daidzein + low-dose YJC groups, respectively. Pathological examination revealed slightly decreased cavernous sinuses and blood vessels in the corpus cavernosum of the rats in the daidzein + testosterone, daidzein + sildenafil, daidzein + medium-dose YJC, and daidzein + high-dose YJC groups as compared with those in the blank control group.

CONCLUSIONHigh-dose Yangjing Capsule is efficacious for the recovery of erectile function in rats, especially for phytoestrogen-induced erectile dysfunction.

Contemporary pharmacological research has demonstrated that puerarin, the most important phytoestrogen extracted from Pueraria lobata(Willd.) Ohwi, has protecting functions on the cardiovascular system, nervous system, osteoporosis, liver injury, and inflammation in vivo and in vitro. Most of these research studies focused on inhibiting oxidative stress and apoptosis through regulating various bioactivators and signal pathways. Among these, superoxide dismutase (SOD), endothelial nitric oxide synthase (eNOS) and malondialdehyde (MDA), and PI3K/Akt, MAPK, and NF-κB are of great importance. The data cited in this review were mainly obtained from articles listed in PubMed and Elsevier SDOL published from 1959 to 2013, and the search term used was "puerarin".
