Evaluation of Biochemical and Molecular Parameters of Patients Suffering from Chronic Viral Hepatitis B Treated by a Medicinal Plant Recipe of a Health Care Practitioner in Burkina Faso

Chronic viral hepatitis B (HBV) remains a major public health problem in Burkina Faso. Since access to diagnostic tests and treatments is limited because of their high cost, the majority of the population turn to traditional herbal treatments. This study aimed to evaluate the effectiveness of a plant recipe called Hepatib tiben. It consisted of comparing certain biochemical and molecular parameters of patients infected with HBV that were supported by the recipe. The patients were recruited in Ouagadougou by the traditional health practitioner according to the requirements of the study. Thus 44 patients aged 20 to 61 years and carrier of HBsAg for at least 06 months were treated with Hepatib tiben. The tests were performed in the laboratory before and three months after the treatment. ELISA tests were used to confirm the presence of HBsAg and search for anti-HCV antibodies;transaminases, creatinine were quantified by the “Chem 400” automaton and the viral load of HBV by Real-time PCR. The analysis of the results reveals an improvement of the biochemical and molecular parameters of the patients with the following means (ASAT: 21.02 ± 9.97;ALAT: 21.11 ± 13.27;DNA: 1571.82 ± 3990.97 with p = 0.01 for each). As for HBsAg, its disappearance was observed in 4.55% of patients after treatment. The evaluation of the creatinine parameter explained that the recipe of plants has a tolerated effect on the kidneys of treated patients. These results, while encouraging, need to be complemented by further research for the development of effective phytomedicine to treat and eliminate this viral hepatitis B virus.

Mechanism of Jianpi Qingchang Huashi Recipe in treating ulcerative colitis:A study based on network pharmacology and molecular docking

BACKGROUND Ulcerative colitis(UC)is a refractory intestinal disease with alternating onset and remission and a long disease course,which seriously affects the health and quality of life of patients.The goal of treatment is to control clinical symptoms,induce and maintain remission,promote mucosal healing,and reduce recurrence.Clinical trials have shown unsatisfactory clinical response rates.As a supplementary alternative medicine,traditional Chinese medicine has a rich history and has shown good results in the treatment of UC.Because of the quality of herbal medicine and other factors,the curative effect of traditional Chinese medicine is not stable enough.The mechanism underlying the effect of Jianpi Qingchang Huashi Recipe(JPQCHSR)on inducing UC mucosal healing is not clear.AIM To investigate the potential mechanism of JPQCHSR for the treatment of UC based on network pharmacology and molecular docking.METHODS Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform was used to extract the active components and action targets of JPQCHSR,and the target names were standardized and corrected through UniProt database.The related targets of UC were obtained through GeneCards database,and the intersection targets of drugs and diseases were screened by jvenn online analysis tool.The visual regulatory network of"Traditional Chinese medicine-active components-target-disease"was constructed using Cytoscape software,the protein interaction network was constructed using STRING database,and enrichment analysis of gene ontology and Kyoto Encyclopedia of Genes and Genomes pathways was conducted through R software.At last,the active components were docked with the core target through SYBYL-X 2.1.1 software.RESULTS Through database analysis,a total of 181 active components,302 targets and 205 therapeutic targets were obtained for JPQCHSR.The key compounds include quercetin,luteolin,kaempferol,etc.The core targets involved STAT3,AKT1,TP53,MAPK1,MAPK3,JUN,TNF,etc.A total of 2861 items were obtained by GO enrichment analysis,and 171 items were obtained by KEGG(Kyoto Encyclopedia of Genes and Genomes)pathway enrichment analysis.The results of molecular docking showed that the key active components in JPQCHSR had certain affinity with the core target.CONCLUSION The treatment of UC with JPQCHSR is a complex process of multi-component,multi-target and multi-pathway regulation.The mechanism of this Recipe in the treatment of UC can be predicted through network pharmacology and molecular docking,so as to provide theoretical reference for it to better play its therapeutic role.

Effect of Gengnianchun Recipe (更年春方) on Bone Mineral Density, Bone Biomechanical Parameters and Serum Lipid Level in Ovariectomized Rats

Objective： To observe the effect of Gengnianchun Recipe （更年春方, GNC） on bone mineral density （BMD）, bone biomechanical parameters and serum lipid level in the bilaterally ovariectomized （OVX） rats and to explore the prophylactic and therapeutic action of GNC on ovariectomy induced osteoporosis and hyperlipidemia. Methods： OVX SD rats, 10- 12 months old, were divided into different groups and fed with GNC 2 g/d, GNC 1 g/d and Nilestriol 0. 125 mg/week, respectively for 4 months to observe the change of BMD and bone biomechanical parameters of the lumbar vertebrae, and the serum levels of total cholesterol （TO）, triglyceride（TG）, high-density lipoprotein cholesterol （HDL-C） and low-density lipoprotein cholesterol （LDL-C）, and to compare the effect of the two drugs on the morphology of the uterus. Results： There was marked reduction in BMD and biomechanical parameters in lumbar vertebrae （ P〈0. 01 ） and increase of serum TO and LDL-C levels （ P〈0. 01 ） in rats after OVX. GNC or Nilestriol significantly improved the decreased BMD and biomechanical parameters of the lumbar vertebrae （ P〈0.05 or P〈0. 01 ）, and reduced the serum TO and LDL-C levels （ P〈0. 01 ）. In the Nilestriol group, the wet weight of uterus got increased obviously （ P〈0.01 ）, the number of uterine glands increased, uterine columnar epithelium thickened, and the mitotic figures in the epithelial stroma and myointimal cells augmented. But no such effect in wet weight and morphology of uterus was found in the GNC group. Conclusion： GNC could increase the BMD and biomechanical parameters of the lumbar vertebrae, reduce the serum TO and LDL-C levels, yet produce no adverse reaction in stimulating proliferation and hypertrophy of uterus.

Effect of Bushen Yiqi Huoxue Recipe on Placental Vasculature in Pregnant Rats with Fetal Growth Restriction Induced by Passive Smoking

Interactions of vascular endothelial growth factor （VEGF） with receptors VEGFR1/Fltl and VEGFR2/Flk1, and those of angiopoietins （Ang-1, Ang-2） with receptor Tie2 play important roles in placental angiogenesis. This study investigated vascular morphology and expression of these angiogenic factors in rat placenta on the day 15, 18, 21 of gestation （D 15, D 18 and D21）. The rats were randomly assigned into 3 groups： normal group, model group [fetal growth restriction （FGR） model], and Bushen Tqi Huoxue （BYHR） recipe treatment group （BYHR group, the pregnant rats with FGR were treated with BYHR recipe）. Morphological analysis indicated that during initial villous formation, fetal nucle- ated erythrocytes （FNEs） appeared in maternal blood sinus （MBS）. Subsequently, FNEs were sur- rounded by endothelial cells to form fetal capillary （FC） and then by trophoblast cells to form villi. As pregnancy proceeded, FC density increased progressively with increasing endothelial identification staining （EIS） in normal and BYHR groups. Whereas, villous formation was suppressed, normal in- crease in FC density was impaired and EIS was weakened in model group. Quantitative PCR analysis showed that VEGF and Flkl mRNA increased over gestation in all groups, indicating that VEGF might play a pivotal role in FC growth during late gestation. VEGF mRNA was increased on D15, while de- creased on D21 in model group as compared with normal group and BYHR group. Immunohistochemi- cally, Ang-2 protein was highly expressed in FNEs, gradually disappeared as villi matured, and decreased over gestation in all groups, indicating that Ang-2 might play a pivotal role in villous formation, which was further supported by decreased Ang-2 mRNA and protein expression in model group on D 15. Ang-1 mRNA, Tie2 mRNA and Ang-1/Ang-2 ratio increased from D15 to D18 in all groups as placenta matured. Ang-1 mRNA, Tie2 mRNA and Ang-1/Ang-2 ratio were decreased on D18 in model group as compared with normal and BYHR groups, indicating delayed maturity of FGR placenta. Alterations in angiogenic factors may result in altered placental vasculature and cause placental insufficiency. BYHR recipe could balance the angiogenic factors to promote the formation and maturation of FGR placental vasculature.

Objective: To evaluate the clinical efficacy of Ganxian recipe (肝纤方, GXR) and lamivudine (LVD) in a two-year treatment of chronic hepatitis B (CHB). Methods: One hundred and twenty patients with CHB were randomly divided into the combinedly treated group (combined group) of 40 CHB patients who were treated with GXR combined with LVD. Another 40 CHB patients were treated with LVD alone (WM group), and still another 40 CHB patients were treated with GXR alone (TCM group). All these cases were randomly controlled and observed for two years. Results: Comprehensive efficacy: Total effective rate of the combined group (complete response and partial response) was 92.5%, while that of the WM group was 67.5% and TCM group 57.5%, respectively, with the difference between them was significant ( P <0.01); after treatment, the hepatic functions (AST, ALT, SB) of the three groups were all reduced, and the reduction in the combined group was particularly significant in comparison with the WM group or TCM group, P <0.05 or P < 0.01 respectively, suggesting that the effect in the combined group was better than that in the other two groups; the rate of tyrosine-methionine-aspartate-aspartate (YMDD) virus mutation: it was 7.5% in the combined group, 40.0% in the WM group, and 5.0% in the TCM group; liver fibrosis improvement parameter: after treatment, the results in the combined group got better than those in the other two groups. Conclusion: GXR could inhibit the appearance of YMDD after long-term application of LVD, and combined use has marked synergism.

Shenkang Ⅶ Recipe Attenuates Unilateral Ureteral Obstruction-induced Renal Fibrosis via TGF-β/Smad, NF-κB and SHH Signaling Pathway

This study aimed to explore the protective effects of the traditional Chinese Medicine formula Shenkang Ⅶ recipe(SK-7)on renal fibrosis and the mechanisms.Renal fibrosis was induced by unilateral ureteral obstruction(UUO)in rats.The rats were then divided into 5 groups:control group(Sham operation),UUO model group,UUO model plus low to high doses of SK-7(0.5,1.0,or 2.0 g/kg/day,for 14 days)groups.The animals were sacrificed on the 7th or 14th day.K idney tissues were collected for histopathological exarminations(hematoxylin and cosin and Masson's trichrome staining).Immunohistochemistry was used to detect the expression of collagen type II(Col II),fibronectin(FN),α-smooth muscle actin(a-SMA),TIMP metallopeptidase inhibitor 2(TIMP2),matrix metallopeptidase 2(MMP2),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and monocyte chemotactic protein-1(MCP-1).The TGF-β1/Smad,NF-κB and Sonic hedgehog signaling proteins were detected by Western blotting.Our results showed that SK-7 prevented UUO-induced renal injury and accumulation of collagen fibrils.Renal fbrosis biomarkers Col Ⅲ,FN,α-SMA and TMP2 were increased in the rats after UUO and decreased by SK-7,while MMP2 was upregulated after treatment.SK-7 also suppressed the levels of TNF-α,IL-1βand MCP-1 in UUO rats.In addition,SK-7 inhibited activation of the TGF-B/Smad,NF-κB and sonic hedgehog signaling(SHH)pathways.Taken together,these findings suggest that SK-7 may regulate the synthesis and degradation of extracellular matrix,reduce inflammation and suppress the proliferation of fibroblasts,by blocking the TGF-β1/Smad,NF-κB and SHH signaling pathways to exert its anti-renal fbrosis effect in UUO rats.

Influence of Shenqing Recipe on Morphology and Quantity of Colonic Interstitial Cells of Cajal in Trinitrobenzene Sulfonic Acid Induced Rat Colitis

Objective To observe the influence of Shenqing Recipe (SQR), a kind of Traditional Chinese Medicine, on the morphology and quantity of colonic interstitial ceils of Cajal (ICC) in trinitrobenzene sulfonic acid (TNBS)-induced rat colitis, and to investigate the possible mechanism of SQR in regulating intestinal dynamics. Methods Sixty rats were randomly divided into normal control, model Ⅰ , model Ⅱ, mesalazine, and high-dose, and low-dose SQR groups with 10 rats in each group. TNBS (10 mg) dissolved in 50% ethanol was instilled into the lumen of the rat colon of the latter five groups to induce colitis. On the 4th day after administration of TNBS, each treatment group was administered one of the following formulations by enteroclysis gavage once a day for 7 days: 600 mg·kg^-1·d^-1 mesalazine, 2.4g^-1·d^-1 SQR, and 1.2g^-1·d^-1 SQR. Model Ⅱ rats received normal saline solution. After 7 days colonic samples were collected. While the colonic samples of model I group were collected on the 3rd day after TNBS administered. Ultrastructure of ICC in the damaged colonic tissues was observed with transmission electron microscope. Expression of c-kit protein in colonic tissue was determined by immunohistochemical staining and Western blot. Results The ultrastructure of colonic ICC in the rat model of TNBS-induced colitis showed a severe injury, and administration of SQR or mesalazine reduced the severity of injury. Similarly, the expression of c-kit protein of TNBS-induced colitis rat model was significantly decreased compared with the normal control group (P〈0.05). Treatment with SQR or mesalazine significantly increased the expression of c-kit protein compared with the administration of control formulations (P〈0.05), especially the high-dose SQR group. Conclusion SQR could alleviate and repair the injured ICC, and improve its quantity, which might be involved in regulating intestinal motility.

Clinical Study on Zhuyu Tongfu (逐瘀通腑) Serial Recipe Combined with Acupuncture and Massotherapy in Treating Hypertensive Cerebral Hemorrhage

Objective. To observe the clinical efficacy and mechanism of Zhuyu Tongfu （逐瘀通腑, ZYTF） Serial Recipe combined with acupuncture and massotherapy in treating hypertensive cerebral hemorrhage （HCH）. Methods： One hundred and eighteen patients with hypertensive cerebral hemorrhage, on the basis of conventional Western medicine treatment, were randomly divided into ZYTF combined with acupuncture and massotherapy group （treated group） and simple Western medicine group （control group） ; the clinical efficacy, neurofunction deficit scoring （NDS） alterations and hematoma absorption rate of both groups were observed, and also the plasma superoxide dismutase （SOD） activity, plasma lipid peroxidase （LPO） content, erythrocyte glutathion peroxidase （GSH-Px） activity, hematocrit （Ht） and the whole blood viscosity （Va） change were also observed. Results： In the treated group, the clinical efficacy, NDS improvement and hematoma absorption rate were superior to that of the control group; comparison between the two groups after treatment showed that plasma SOD activity and GSH-Px activity got more elevated and plasma LPO content, Ht and Va more lowered in the the treated group than those in the control group. Cenclusien： ZYTF combined with acupuncture and massotherapy has better effect, its therapeutic mechanism was possibly correlated to the elevation of plasma SOD activity, GSH-Px activity and lowering of plasma LPO content, Ht and Va.

Effect of coke properties and its blending recipe on performances of carbon anode for aluminium electrolysis

The properties and blending recipe of petroleum cokes used to make high quality carbon anodes for aluminium electrolysis were studied. Three kinds of green cokes were selected for bench scale study to illustrate the effects of cokes properties and its blending recipe on anode performances. The results show that impurities derived mainly fi＇om cokes remarkably affect the CO2 reactivity and air reactivity of carbon anodes. Ca, Na and V can increase CO2 reactivity of calcined cokes but S has the contrary effect, and the cokes of high V level generally present high air reactivity. The anodes with good quality can be made by properly selecting and scientifically blending of cokes, some poor quality cokes can also be used to produce high quality anodes with a reasonable blending recipe. Na contaminated anodes have high CO2 reactivity and air reactivity, so the recycled anode butts should be well cleaned to reduce Na content before being introduced into anode production, which is especially important to the low S cokes.
