Abstract
ETHNOPHARMACOLOGICAL RELEVANCE You-Gui-Yin (YGY) is a traditional Chinese recipe used for reinforcing kidney essence which is recorded in Jingyue Quanshu written by Zhang Jingyue in Ming dynasty. According to traditional Chinese medicine theory, kidney essence is associated with brain and without sufficient kidney essence, cognitive impairment may occur. AIM OF THE STUDY In this study, we aimed to investigate the effect of YGY extract on cognitive impairment of chronic renal failure (CRF) mice and explore the mechanisms involved. MATERIALS AND METHODS Aqueous extract of YGY was prepared from crude drugs and was quality controlled by high-performance liquid chromatography (HPLC). CRF was induced by 0.2% adenine in mice and CRF mice were intragastrically administered with 1.5 g kg-1, 3.0 g kg-1, and 6.0 g kg-1 of YGY extract. Mice were identified with CRF by determining several biochemical and physiological indexes, including creatinine clearance rate, serum creatinine, serum urea nitrogen, serum Ca, serum P, serum Mg, body weight and body temperature. Morris water maze and novel object recognition tests were conducted for evaluation of cognitive function. In addition, changes of CaMKIIα/CREB/BDNF and EPO/EPOR pathways in hippocampus were examined by detecting the protein expressions of CaMKIIα, p-CaMKIIα (Thr286), CREB1, p-CREB1 (Ser133), BDNF, EPO, EPOR, p-EPOR (Tyr485), STAT5, and AKT1 using western blotting assays. Also, the primary EPO-producing cells in brain (i.e. astrocytes) and EPO expression regulator HIF-2α were checked by fluorescence microscopy and western blotting assay, respectively. RESULTS Nine components in YGY extract were figured out and monitored with their contents by HPLC for the quality control of YGY extract. Biochemical and physiological measurements validated the success of induction of CRF in mice, and YGY extract significantly retarded the CRF progression and ameliorated the CRF-induced cognitive impairment. The behavioral tests showed that compared with normal control mice, CRF mice had impaired cognitive function. However, treatment of YGY extract significantly ameliorated the cognitive impairment of CRF mice. Additionally, decreased expressions of hippocampal CaMKIIα, p-CaMKIIα (Thr286), CREB1, p-CREB1 (Ser133), and BDNF were observed in the hippocampus of CRF mice, but YGY extract significantly restored these protein expressions. Moreover, hippocampal EPO, EPOR, p-EPOR (Tyr485), STAT5, AKT1, and HIF-2α, as well as the number of astrocytes in CA1 zone of hippocampus were also decreased in CRF mice, while YGY extract prominently promoted the expressions of these proteins and increased the number of astrocytes. CONCLUSIONS All the data in this study suggested that YGY extract ameliorated the cognitive impairment of CRF mice, and this amelioration was related to up-regulating the CaMKIIα/CREB/BDNF and EPO/EPOR pathways.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anthocleista vogelii Planch is a medicinal plant traditionally used in West Africa for the management and treatment of diabetes mellitus. AIM OF THE STUDY To determine the antidiabetic activities of chloroform fraction (CF) of Anthocleista vogelii Planch root bark in rats with diet- and alloxan-induced obesity-diabetes. MATERIALS AND METHODS Inhibitory activities of CF against α-amylase and α-glucosidase activities were determined in vitro. Three weeks old rats were fed with high-fat diet for 9 weeks to induce obesity prior to further induction of diabetes using alloxan (150 mg/kg body weight, i.p.). Blood glucose levels and body weight were measured every 7 days throughout the experiment. Glucose tolerance was assessed in normal and CF-treated rats on day 21. Terminal blood samples were collected from sacrificed animals for the measurement of serum insulin levels. Pancreases were excised from treated and untreated animals for histopathological examination. RESULTS LCMS/MS chromatographic profile of CF via positive and negative modes revealed 13 and 23 compounds respectively. Further analysis revealed quebrachitol (QCT), loganin, sweroside, oleoside 11-methyl ester and ferulic acid, which have been previously reported for their antidiabetic activities, as constituents of CF. CF inhibited activities of α-amylase (IC50 = 51.60 ± 0.92 µg/ml) and α-glucosidase (IC50 = 5.86 ± 0.97 µg/ml) in a dose-dependent manner. Treatment of animals with obesity-diabetes with 100 and 200 mg/kg CF significantly improved glucose tolerance (P < 0.001) and enhanced serum insulin levels (P < 0.05) compared to diabetic control rats. CONCLUSIONS Antidiabetic activities of CF might be mediated via inhibition of α-amylase and α-glucosidase activities, elevation of serum insulin concentration, and enhancement of insulin and leptin sensitivity in obesity-diabetes rats. This study further substantiates the traditional use of A. vogelii in the management and treatment of diabetes in Africa and encourages further studies to investigate its mechanism of action.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cornus officinalis (Cornaceae), known in Chinese as "Shanzhuyu," is a frequently used traditional Chinese medicine. It tastes sour and is astringent and slightly warm in nature. Its fruits have long been used to treat kidney deficiency, high blood pressure, waist and knee pain, dizziness, tinnitus, impotence, spermatorrhea, menorrhagia, and other diseases in China. The main distribution areas are Shanxi and Gansu. AIM OF THE STUDY This review focused on the ethnopharmacological uses of the herb. We also focus on the phytochemical, pharmacological, and toxicological studies on C. officinalis. The recent analytical methods developed for the quality control of the herb's constituents are also reviewed. Additionally, future trends and prospects in the study of this herb are proposed. MATERIALS AND METHODS Information on C. officinalis was gathered by searching the internet (PubMed, ScienceDirect, Wiley, ACS, CNKI, Scifinder, Web of Science, Google Scholar, and Baidu Scholar) and libraries. RESULTS This review compiled the ethnopharmacological uses, including the classic prescriptions and historical applications. Approximately 300 chemical compounds have been isolated and identified from C. officinalis. The major active components of the plant are organic acids and iridoids, among which morroniside and loganin have been extensively investigated. The fruit of the plant has been used in treating many diseases in traditional medicine. Scientific studies indicated the herb's wide range of pharmacological activities, such as hepatic and renal protection, antidiabetes activity, cardioprotection, antioxidation, neuroprotection, antitumor activity, anti-inflammation, analgesic effects, antiaging activity, antiamnesia, antiosteoporosis, and immunoregulation. The analytical methods developed for the quantitative and qualitative determination of various compounds in the herb were further reviewed. CONCLUSIONS In this paper, we reviewed various studies conducted on C. officinalis, especially in areas of its ethnopharmacological use, as well as on its phytochemistry, pharmacology, and modern analytical methods used. Some of the herb's ethnomedical indications have been confirmed by the herb's pharmacological effects, such as its hepatic and renal protection and the antidiabetic effects. In particular, the crude extract and its chemical composition have exerted good therapeutic effect in diabetic treatment. C. officinalis entails additional attention on its pharmacological effects and drug development to expand its effective use clinically. Many advanced technologies are used for quality testing, but the detection component is exceedingly scarce for synthetically evaluating the quality of C. officinalis herbs. Thus, further research is necessary to investigate the quality control and toxicology of the plant, to further elucidate its clinical use, and to control herbal quality.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Reproductive healthcare has been highlighted as a major challenge in Lesotho mainly due to the high prevalence of HIV/AIDS and sexually transmitted infections. As a result other reproductive ailments have not received much attention, particularly because healthcare facilities are already limited and many of them are inaccessible. For these reasons, medicinal plants play a major role in primary healthcare system in the country, in addition the plants are easily accessible, more affordable, and their use forms part of the cultural heritage. However, documentation of medicinal plants used for reproductive ailments is scattered, more importantly the biological and pharmacological properties, as well as toxicity of many of these plants are not yet known. AIM OF THE STUDY To document the plants used by both male and female Basotho (residing in Lesotho) for the treatment of reproductive ailments, to explore their recorded biological and pharmacological effects as well as their toxicity, and to establish if these plants are used for similar purposes in other southern African cultures. MATERIALS AND METHODS The results stem from published findings of recent interviews of traditional medicinal practitioners in the Maseru District of Lesotho, first author's own experiences and observations from the Qacha's Nek District as well as comprehensive literature survey including numerous books and unpublished data. Electronic databases such as Google, Google Scholar, PubMed, and ScienceDirect were also used to search for the chemical compounds, pharmacological activity, and toxicity of the plants. RESULTS A total of 87 plant species are reported to be used for the treatment of several reproductive problems such as infertility, complications associated with pregnancy (twelve plants are used to treat conditions such as colic, heartburn, nausea, and constipation), cleansing and/ or toning of the uterus (with a purpose either to induce pregnancy or to get rid of the placenta, for example Withania somnifera and Zantedeschia albomaculata), difficult childbirth, as well treatment of breast and cervical cancer, cysts, fibroids, and testicular tumours (e.g. Hypoxis hemerocallidea). For the toning of the uterus, it is common to use a combination of plants, e.g. Gunnera perpensa, Scabiosa columbaria, and Eriospermum ornithogaloides. CONCLUSIONS Of the 87 plants used for reproductive healthcare, the highest number (31) is used for the treatment of infertility (in both men and women). The pharmacological effects, active compounds, and toxicology of many of these plants are not yet known.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE You-Gui pills (YGPs) are an effective traditional Chinese formula being used clinically for the treatment of multiple sclerosis (MS). Previous studies demonstrated that YGPs exerted the potent neuroprotective effects in murine models of experimental autoimmune encephalomyelitis (EAE), which is an equivalent animal model for multiple sclerosis (MS). However, the mechanism of YGPs functions remained unclear. AIM OF THIS STUDY The aim of this study was to evaluate the therapeutic effect of YGPs in MOG35-55-induced EAE mice and to further elucidate the underlying molecular mechanism. METHODS Female C57BL/6 mice were divided into six groups, including the non-treated EAE model, prednisone acetate- and 1.2, 2.4 or 4.8g/kg YGPs-treated EAE groups, and a normal control group. The EAE model was established by injecting the mice subcutaneously with MOG35-55 antigen. The body weights were measured and the neurological functions were scored in each group. The pathology and morphology of the brain and spinal cord was examined. The expression of MAP-2 was detected by immunofluorescent staining. The levels of netrin1, DCC, RhoA, Rac1, and Cdc42 were assayed by immunohistochemistry, qRT-PCR and Western blot on day 40 post-immunization (PI). RESULTS YGPs treatments significantly reduced neurological function scores in EAE mice, where the inflammatory infiltration was reduced and the axon and myelin damage in both brain and spinal cord was alleviated. In the brain and spinal cord tissues, YGPs increased the expression of neuronal factors MAP-2, netrin1 and DCC. The expression of Rac1 and Cdc42 were increased, while RhoA was reduced following YGPs treatments. CONCLUSION Our results demonstrated that YGPs exhibited a neuroprotective effect on promoting nerve regeneration at the brain and spinal cord in EAE mice induced by MOG35-55. Netrin1, DCC and the Rho family GTPases of RhoA, Racl, Cdc42 were involved in mediating the effects of YGPs on nerve regeneration.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ba-Wei-Die-Huang-Wan (BWDHW) is the traditional Chinese medicine formula containing eight ingredients, namely Rehmannia glutinosa (Gaetn.) DC., root, steamed & dried; Cornus officinalis Siebold & Zucc., fructus, dried; Dioscorea oppositifolia L., root, dried; Alisma plantago-aquatica, subsp. orientale (Sam.) Sam., tuber, dried; Poria cocos (Fr.) Wolf., sclerotium, dried; Paeonia×suffruticosa Andrews, bark, dried; Cinnamomum cassia (Nees & T.Nees) J. Presl, bark, dried; Aconitum carmichaeli Debeaux, lateral root, dried & processed. It has been used for diabetes and urinary frequency treatments. AIM OF THE STUDY We investigate effects of BWDHW on cyclophosphamide (CYP)-induced ongoing bladder overactivity and acidic adenosine triphosphate (ATP) solution-induced hyperactivity on rat's prestimulated bladder. MATERIAL AND METHODS Female Wistar rats were injected with intraperitoneal CYP (100mg/kg) or saline respectively. Rats were treated with BWDHW (90mg/kg/day) or vehicle for the next five days. After treatments animals were evaluated both in metabolic cage model and then by cystometry. Acidic ATP solution (5mM, pH 3.3) was instilled to provoke bladder hyperactivity. Bladder mucosa and muscle proteins were assessed by Western blotting. RESULTS As compared to the controls, the CYP group showed significantly decreased mean cystometric intercontractile interval and increased micturition frequency, whereas the CYP/BWDWH group did not. The CYP group had significant protein overexpression in mucosal M2, M3, P2X2, and P2X3 receptors as well as detrusor M2 and M3 receptors. However, the CYP/BWDWH group had insignificant changes from controls. In the provoking test, the control/BWDHW and CYP/BWDHW groups were less affected by acidic ATP stimulation of intercontractile interval changes than the control group. Compared to the control group, the control/BWDHW group showed significantly lower mucosal P2X3 protein expression and the CYP group showed significant mucosal TRPV1 protein upregulation after the provoking test. CONCLUSION BWDHW treatment can ameliorate CYP-induced ongoing bladder overactivity and suppress mucosal P2X2, P2X3, M2, and M3 receptor protein overexpression, as well as detrusor M2 and M3 receptor protein overexpression. BWDHW pretreatment can reduce acidic ATP solution-provoked hyperactivity by preventing TRPV1 receptor overexpression in CYP-treated bladder mucosa and inhibiting P2X3 receptor overexpression in naïve bladder mucosa.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE You-gui Pill (YGP), a traditional Chinese medicinal prescription, was widely used to warm and recuperate "kidney-yang" clinically for hundreds of years in China. Recent studies found that YGP had a potential benefit for renoprotection. AIM OF THE STUDY The present study aimed to elucidate the in vivo and in vitro efficacy of YGP on renal tubulointerstitial fibrosis, and the molecular mechanism is also investigated. MATERIALS AND METHODS Rat renal tubulointerstitial fibrosis model was elicited by unilateral ureteral obstruction (UUO). Sprague-Dawley rats underwent UUO and were studied after 14 days. Animals were randomly subjected to six groups: sham, UUO, UUO/YGP (0.14, 0.42, 1.26g/kg/d), and UUO/enalapril (10mg/kg/d). HE, Masson and ELISA were used for evaluate renal injury and function. Immunohistochemical analysis and western blot were used to detect the expressions of α-SMA, fibronectin, collagen matrix and Smads. In vitro studies were investigated in TGF-β1-stiumlated NRK-49F cell line. RESULTS Oral administration of YGP significantly decreased UUO-induced inflammatory cell infiltration, tubular atrophy and interstitial fibrosis, and there was no significant difference between YGP at 1.26g/kg and enalapril at 10mg/kg treatment (P>0.05). Meanwhile, serum creatinine and blood urea nitrogen levels were reduced dramatically (P<0.01). In coincide with the decreased of TGF-β1, α-SMA, fibronectin and collagen matrix expressions were also declined with YGP treatment in both UUO kidneys and TGF-β1-stimulated NRK-49F cell line. Additionally, nuclear translocation of p-Smad2/3 was markedly down-regulated by YGP (P<0.001), with a relative mild up-regulated expression of Smad7 (P<0.05). CONCLUSIONS Our findings demonstrate that YGP had a renoprotective effect in ameliorating renal tubulointerstitial fibrosis, and this activity possibly via suppression of the TGF-β and its downstream regulatory signaling pathway, including Smad2/3.

Abstract
ETHNOPARMACOLOGICAL RELEVANCE The fruit of Cornus officinalis, called "Shanzhuyu", a traditional medicine in China, is used for the treatment of kidney diseases, including diabetic nephropathy. The aim of this study is to investigate the anti-diabetic nephropathy activity of Shanzhuyu and the active compounds in the fruit. MATERIALS AND METHODS The air dried fruit of Cornus officinalis was extracted in 80% EtOH, the obtained residue was fractioned on D101 resin column eluted with H2O/EtOH solution to get five crude fractions (fr. A-E). The anti-diabetic nephropathy activity of fractions (fr. A-E) was evaluated in vitro by inhibiting the expression of collagen IV (Col V), fibronectin (FN) and IL-6 in high-glucose-induced mesangial cells. By preliminary bio-assay screenings, repeated column chromatography on fraction B-D led the isolation of 22 compounds, whose structures were determined by extensive spectroscopic analysis, and the anti-diabetic nephropathy activity of the isolated compounds was also evaluated. RESULTS Two new iridoid glucosides, logmalicids A and B (1 and 2), together with 20 known compounds (3-22) were isolated from the extract of Shanzhuyu under the bioassay-guided screenings. The anti-diabetic nephropathy activity assay displayed that fractions A, D and E could significantly inhibit the production of Col IV; fractions A and C could significantly inhibit the expression of FN and IL-6 in the high-glucose-stimulated mesangial cells at concentration of 50 μg/mL; and loganin (3) and its derivatives (1 and 2) could significantly inhibit the expression of FN and IL-6 at concentration of 10 μM, respectively. CONCLUSIONS The results suggested that loganin and its derivatives were the active compounds in Cornus officinalis fruit (Shanzhuyu) on diabetic nephropathy. This study further supported the traditional use of Shanzhuyu to treat diabetic nephropathy and related kidney diseases.
