RESUMO

Our previous study has revealed that malonyl-ginsenosides from Panax ginseng (PG-MGR) play a crucial role in the treatment of T2DM. However, its potential mechanism was still unclear. In this study, we investigated the anti-diabetic mechanisms of action of PG-MGR in high fat diet-fed (HFD) and streptozotocin-induced diabetic mice and determined the main constituents of PG-MGR responsible for its anti-diabetic effects. Our results showed that 16 malonyl ginsenosides were identified in PG-MGR by HPLC-ESI-MS/MS. PG-MGR treatment significantly reduced fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels and improved insulin resistance and glucose tolerance. Simultaneously, PG-MGR treatment improved liver injury by decreasing aspartate aminotransferase (AST) and alanine aminotransferase (ALT) expression. Furthermore, Western blot analysis demonstrated that the protein expression levels of p-PI3K/PI3K, p-AKT/AKT, p-AMPK/AMPK, p-ACC/ACC and GLUT4 in liver and skeletal muscle were significantly up-regulated after PG-MGR treatment, and the protein expression levels of p-IRS-1/IRS-1, Fas and SREBP-1c were significantly reduced. These findings revealed that PG-MGR has the potential to improve glucose and lipid metabolism and insulin resistance by activating the IRS-1/PI3K/AKT and AMPK signal pathways.

RESUMO

American ginseng (Panax quinquefolius L.) is popularly consumed as traditional herbal medicine and health food for the treatment of type 2 diabetes mellitus (T2DM). Malonyl ginsenosides (MGR) are the main natural ginsenosides in American ginseng. However, whether the malonyl ginsenosides in P. quinquefolius (PQ-MGR) possess antidiabetic effects has not been explored yet. In this study, the antidiabetic effects and the underlying mechanism of PQ-MGR in high-fat diet/streptozotocin (HFD/STZ)-induced T2DM mice were investigated. The chemical composition was analyzed by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). Our results showed that 14 malonyl ginsenosides were identified in the PQ-MGR. Among them, the content of m-Rb1 represented about 77.4% of the total malonyl ginsenosides. After a 5-week experiment, the PQ-MGR significantly reduced the fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), nonesterified fatty acid (NEFA), alanine transaminase (ALT), and aspartate transaminase (AST) levels and improved glucose tolerance and insulin resistance. Furthermore, Western blot analysis demonstrated that the protein expressions of p-PI3K, p-AKT, p-AMPK, p-ACC, PPARγ, and GLUT4 in the liver and skeletal muscle were significantly upregulated after PQ-MGR treatment. In contrast, the protein expressions of p-IRS1 and p-JNK were significantly downregulated. Our results revealed that PQ-MGR could ameliorate glucose and lipid metabolism and insulin resistance in T2DM via regulation of the insulin receptor substrate-1/phosphoinositide3-kinase/protein-kinase B (IRS1/PI3K/Akt) and AMP-activated protein kinase/acetyl-CoA carboxylase (AMPK/ACC) pathways. These findings suggest that PQ-MGR may be used as an antidiabetic candidate drug for T2DM treatment.

RESUMO

A dredging demonstration project in the Baiyangdian Lake included open waters and fishing ponds to reduce the internal release of nitrogen and phosphorus from bottom sediments. The dredging depth design was determined by both the sediment vertical distribution profile of total nitrogen and phosphorus, and the sediment adsorption-desorption equilibrium method. The determined dredging depths were very similar and coincident. The dredging depth for the demonstration area of open waters in Nanliuzhuang was identified as(50±10) cm; and the dredging depths for fishing ponds were(30±10) cm in both the Nanliuzhuang and Caiputai demonstration areas. The equilibrium nitrogen(NH4+-N) and phosphorus(SRP) concentrations at zero net sorption or desorption(ENC0 and EPC0) were significantly positively correlated with both exchangeable and total nitrogen and phosphorus in the sediments. The total nitrogen and phosphorus in the sediments were also used to predict the risk of their release from the bottom sediments to the overlying water column. The sediment layers with ENC0 and EPC0 values greater than the NH4+-N and SRP in the overlying water column indicated the sediments act as a source of dissolved nitrogen and phosphorus to the overlying water column in the Nanliuzhuang and Caiputai demonstration areas. Accordingly, the sediment layers with both total nitrogen concentrations greater than 750 mg·kg-1 and total phosphorus concentrations greater than 500 mg·kg-1 should be identified as dredging layers.

RESUMO

OBJECTIVE: To systematically evaluate the clinical efficacy and safety of acupuncture in the treatment of Tic Disorders (TD) in children, and to clarify the current evidence regarding the clinical application of acupuncture in the treatment of TD. METHODS: Randomized controlled trials (RCTs) comparing acupuncture treatment with pharmaceutical treatment for TD were included in this review. A comprehensive search of 6 electronic literature databases was conducted, and the retrieval date was from the establishment of the database to April 2020. The Cochrane Collaboration's bias risk assessment tool was used to evaluate the bias risk of the included literature, and adopted the Review Manager 5.3 was used for statistical analysis of the data in the included literature. RESULTS: A total of 22 RCTs (1668 participants) were included in this review. Meta-analysis indicated that acupuncture showed superior effects in the following aspects, including higher overall effective rate [RR = 1.20,95 % CI(1.09,1.20),P<0.00001], significant reduction in Yale Global Tic Severity Scale (YGTSS) scores [MD=-2.79,95 %CI(-4.75,-0.82),P = 0.005], lower incidence of adverse effects [RR = 0.26,95 %CI(0.17,0.41),P<0.00001], and reduced recurrence rate [RR = 0.28,95 %CI(0.17,0.46),P<0.00001]. CONCLUSION: Acupuncture treatment alone is more effective in the treatment of TD than pharmaceutical treatment, as seen in the reduction of YGTSS scores, fewer adverse effects and lower recurrence rates.

RESUMO

BACKGROUND: The traditional Chinese medicine formula Jiu Wei Zhen Xin Granula (JWZXG) is prescribed to treat generalized anxiety disorder (GAD) in China. This study was to assess the efficacy and safety of JWZXG in patients with GAD. METHOD: Data were pooled from 14 randomized controlled trials involving the assessment of mean changes of Hamilton Anxiety Rating Scale (HAMA) total scores, response rates, adverse event rates, quality, publication bias, and risk of bias. RESULTS: Pooled analysis showed no significant difference in response rate (risk ratio 1.01, 95% CI [0.93-1.08]; Z test = 0.17, P = 0.86) and no significant difference between JWZXG group and azapirones group (RR 0.69, 95% CI [0.45, 1.06]; Z test = 1.69, P = 0.09) in rate of adverse events. Though no difference exists between JWZXG group and azapirones group in HAMA total score from baseline, JWZXG group was inferior to selective serotonin reuptake inhibitors (SSRIs) group (WMD -0.93, 95% CI [-1.64, -0.23]; Z test = 2.6, P = 0.009) which had more adverse events than JWZXG group (RR 0.64, 95% CI [0.46, 0.89]; Z test = 2.63, P = 0.009). CONCLUSIONS: This meta-analysis preliminarily suggests that JWZXG is as effective as azapirones, though having the same possibility of suffering AEs. JWZXG was inferior to SSRIs but causes fewer AEs in the treatment of GAD.

RESUMO

Activation of translocator protein (18 kDa) (TSPO) plays an important role to mediate rapid anxiolytic efficacy in stress response and stress-related disorders by the production of neurosteroids. However, little is known about the ligand of TSPO on the anxiety-like and depressive behaviors and the underlying mechanisms in chronic unpredictable mild stress (UCMS) mice. In the present study, a novel ligand of TSPO, ZBD-2 [N-benzyl-N-ethyl-2-(7,8-dihydro-7-benzyl-8-oxo-2-phenyl-9H-purin-9-yl) acetamide] synthesized by our laboratory, was used to evaluate the anxiolytic and antidepressant efficacy and to elucidate the underlying mechanisms. ZBD-2 (3 mg/kg) significantly attenuated anxiety-like and depressive behaviors in the UCMS mice, which was blocked by TSPO antagonist PK11195 (3 mg/kg). Treatment of ZBD-2 reversed the decrease in biogenic amines (norepinephrine, dopamine, and serotonin) in the brain region of hippocampus in the UCMS mice. The decreases in TSPO, GluN2B-containing N-methyl-D-aspartate (NMDA) receptors, GluA1, p-GluA1-Ser831, p-GluA1-Ser845, PSD-95, and GABAA-a2 were integrated with the increases of CaMKII and iNOS levels in the hippocampus of the UCMS mice. ZBD-2 significantly reversed the changes of above proteins. However, ZBD-2 or PK11195 treatment did not affect the levels of GluN2A-containing NMDA receptors and the total levels of GAD67. Our study provides strong evidences that ZBD-2 has a therapeutic effect on chronic stress-related disorders such as depression and anxiety through regulating the biogenic amine levels and the synaptic proteins in the hippocampus.

RESUMO

Sinomenine, an alkaloid originally isolated from the roots of Sinomeniumacutum, is used as a traditional Chinese medicine for rheumatic arthritis. However, little is known about the neuronal mechanisms underlying the analgesic effects of sinomenine in animals with chronic inflammatory pain. In this study, we investigated the persistent inflammatory pain induced by hind paw injection of complete Freund's adjuvant (CFA) in mice, which was reversed by sinomenine administration. In the anterior cingulate cortex (ACC), a region highly associated with chronic pain processing, the upregulation of GluN2B-containing N-methyl-D-aspartate (NMDA) receptors and Ca2+/calmodulin-dependent protein kinase II, total levels of GluA1, and phosphorylation of GluA1 at Ser831 (p-GluA1-Ser831) were reversed by systemically administrating sinomenine. Furthermore, sinomenine treatment downregulated the mammalian target of rapamycin (mTOR) pathway. Increases in p-mTOR, p-p70S6k, p-S6, and p-4EBP, which were induced by chronic inflammation, were all changed. However, sinomenine did not affect the levels of GluN2A-containing NMDA receptors and p-GluA1-Ser845, as well as the total levels of mTOR, p70S6k, S6, and 4EBP. In conclusion, results indicated that sinomenine reduced the chronic inflammatory pain induced by CFA, at least partially by regulating the GluN2B receptors and mTOR signals in the ACC.

RESUMO

OBJECTIVE: To observe the effect of Pinggan Qianyang Recipe (PQR) on inhibiting angiotensin II (Ang II) induced proliferation and migration of vascular smooth muscle cells (VSMCs) and changes of DNA methylation. METHODS: VSMCs were cultured using tissue explant method, and PQR containing serum was prepared. Primarily cultured VSMCs were divided into four groups, the normal group, the model group, the folate group (folic acid intervention) , and the PQR group. The proliferation and migration of VSMCs was duplicated by Ang II. After 24-h Ang II induced culture, 40 microg/mL folic acid was added to the folate group for 48 h, while 5% PQR containing serum was added to the PQR group for 48 h. The cell growth curve of VSMCs was drawn by using Cell Counting Kit (CCK-8). The proliferative activity of VSMC was determined by MTT assay. The migration of VSMCs was measured by Millicell chamber. The general level of cytosine methylation in cell nucleus was detected via 5-mC antibodies immunofluorescence, and mRNA expression levels of DNA methyltransferase 1 (DNMT1) were measured by Real-time q-polymerase chain reaction (q-PCR). RESULTS: VSMCs were promoted by Ang II at 10(-6) mol/L for 24 h. Compared with the normal group, the proliferative activity and migration quantity of VSMCs obviously increased, and DNA methylation level obviously decreased (P < 0.05, P < 0.01). Compared with the model group, the cell growth, proliferative activity and migration quantity of VSMCs obviously decreased and the general DNA methylation level increased in the folate group and the PQR group (P < 0.05, P < 0.01). Compared with the normal group, the mRNA expression of DNMT1 decreased in the model group (P < 0.01). Compared with the model group, mRNA expression of DNMT1 in Ang II induced VSMCs was obviously enhanced in the folate group and the PQR group (P < 0.01). CONCLUSIONS: PQR could inhibit Ang II induced proliferation and migration of VSMCs, and cause high genomic DNA methylation level. Changes of DNA methylation might be associated with DNMT1 expression.

RESUMO

OBJECTIVE: Sesamin is known for its role in antioxidant, antiproliferative, antihypertensive, and neuroprotective activities. However, little is known about the role of sesamin in the development of emotional disorders. Here we investigated persistent inflammatory pain hypersensitivity and anxiety-like behaviors in the mouse suffering chronic pain. METHODS: Chronic inflammatory pain was induced by hind paw injection of complete Freund's adjuvant (CFA). Levels of protein were detected by Western blot. RESULTS: Administration of sesamin could induce anxiolytic activities but had no effect on analgesia. In the basolateral amygdala, a structure involving the anxiety development, sesamin attenuated the up-regulation of NR2B-containing N-methyl-d-aspartate receptors, GluR1 subunit of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor as well as phosphorylation of GluR1 at Ser831 (p-GluR1-Ser831), and Ca(2+)/calmodulin-dependent protein kinase II (CaMKII-alpha) in the hind paw CFA-injected mice. In the same model, we found that the sesamin blocked the down-regulation of gamma-aminobutyric acid A (GABAA-alpha-2) receptors. CONCLUSION: Our findings show that sesamin reduces anxiety-like behaviors induced by chronic pain at least partially through regulating the GABAergic and glutamatergic transmission in the amygdala of mice.

RESUMO

Our previous studies have demonstrated the critical roles of calcium-stimulated adenylyl cyclase 1 (AC1) in the central nervous system in chronic pain. In the present study, we examined the analgesic effects of NB001, a selective inhibitor of AC1, on animal models of ankle joint arthritis and knee joint arthritis induced by complete Freund's adjuvant injection. NB001 treatment had no effect on joint edema, stiffness, and joint destruction. Furthermore, the treatment failed to attenuate the disease progression of arthritis. However, NB001 treatment (3 mg/kg) significantly weakened joint pain-related behavior in the mouse models of ankle joint arthritis and knee joint arthritis. Results indicated that NB001 exhibited an analgesic effect on the animal models of arthritis but was not caused by anti-inflammatory activities.

RESUMO

Identified and cloned in 1996 for the first time, G protein-coupled oestrogen receptor (ER) 30 (GPR30/GPER) has been a hot spot in the field of sex hormone research till now. In the present study, we examined the effects of low-dose oestradiol (E2) combined with G15, a specific antagonist of GPR30 on ovariectomy (OVX)-induced osteoporosis in rats. Female Sprague-Dawley (SD) rats undergoing OVX were used to evaluate the osteoprotective effect of the drugs. Administration of E2 [35 µg/kg, intraperitoneally (ip), three times/week) combining G15 (160 µg/kg, ip, three times/week) for 6 weeks was found to have prevented OVX-induced effects, including increase in bone turnover rate, decrease in bone mineral content (BMC) and bone mineral density (BMD), damage of bone structure and the aggravation in biomechanical properties of bone. The therapeutic effect of these two drugs in combination was better than that of E2 alone. Meanwhile, the administration of G15 prevented body weight increase or endometrium proliferation in the rats. In conclusion, administration of low-dose E2 combining G15 had a satisfactory bone protective effect for OVX rats, without significant influence on body weight or the uterus. This combination therapy may be an effective supplement of drugs in prevention and treatment for postmenopausal osteoporosis.

RESUMO

OBJECTIVE: To study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites. METHODS: Recruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed. RESULTS: More than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05). CONCLUSION: The differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

RESUMO

The objective of this study is to compare the effects of the two calcium phosphate composite scaffolds on the attachment, proliferation, and osteogenic differentiation of rabbit dental pulp stem cells (DPSCs). One nano-hydroxyapatite/collagen/poly (l-lactide) (nHAC/PLA), imitating the composition and the micro-structure characteristics of the natural bone, was made by Beijing Allgens Medical Science & Technology Co., Ltd. (China). The other beta-tricalcium phosphate (ß-TCP), being fully interoperability globular pore structure, was provided by Shanghai Bio-lu Biomaterials Co, Ltd. (China). We compared the absorption water rate and the protein adsorption rate of two scaffolds and the characterization of DPSCs cultured on the culture plate and both scaffolds under osteogenic differentiation media (ODM) treatment. The constructs were then implanted subcutaneously into the back of severely combined immunodeficient (SCID) mice for 8 and 12 weeks to compare their bone formation capacity. The results showed that the ODM-treated DPSCs expressed osteocalcin (OCN), bone sialoprotein (BSP), type I collagen (COLI) and osteopontin (OPN) by immunofluorescence staining. Positive alkaline phosphatase (ALP) staining, calcium deposition and calcium nodules were also observed on the ODM-treated DPSCs. The absorption water rate and protein adsorption rate of nHAC/PLA was significantly higher than ß-TCP. The initial attachment of DPSCs seeded onto nHAC/PLA was significantly higher than that onto ß-TCP; and the proliferation rate of the cells was also significantly higher than that of ß-TCP on 1, 3, and 7 days of cell culture. The ALP activity, calcium/phosphorus content and mineral formation of DPSCs + ß-TCP were significantly higher than DPSCs + nHAC/LA. When implanted into the back of SCID mice, nHAC/PLA alone had no new bone formation, newly formed mature bone and osteoid were only observed in ß-TCP alone, DPSCs + nHAC/PLA and DPSCs + ß-TCP, and this three groups displayed increased bone formation over the 12-week period. The percentage of total bone formation area had no difference between DPSCs + ß-TCP and DPSCs + nHAC/PLA at each time point, but the percentage of mature bone formation area of DPSCs + ß-TCP was significantly higher than that of DPSCs + nHAC/PLA. Our results demonstrated that the DPSCs on nHAC/PLA had a better proliferation, and that the DPSCs on ß-TCP had a more mineralization in vitro, much more newly formed mature bones in vivo were presented in DPSCs + ß-TCP group. These findings have provided a further knowledge that scaffold architecture has different influence on the attachment, proliferation and differentiation of cells. This study may provide insight into the clinical periodontal bone tissue repair with DPSCs + ß-TCP construct.

RESUMO

In this experiment, different proportions of the cattle manure, tea-leaf, herb and mushroom residues, were used as food for earthworm (Eisenia fetida) to study the growth of the earth-worm. Then the characteristics and transformation of nutrient content and three-dimensional excitation emission matrix fluorescence (3DEEM) of dissolved organic matter (DOM) during vermistabilization were investigated by means of chemical and spectroscopic methods. The result showed that the mixture of different ratios of cattle manure with herb residue, and cattle manure with tea-leaf were conducive to the growth of earthworm, while the materials compounded with mushroom residue inhibited the growth of earthworm. With the increasing time of verimcomposting, the pH in vermicompost tended to be circumneutral and weakly acidic, and there were increases in electrical conductivity, and the contents of total nitrogen, total phosphorus, available nitrogen, and available phosphorus, while the total potassium and available potassium increased first and then decreased, and the organic matter content decreased. 3DEEM and fluorescence regional integration results indicated that, the fluorescence of protein-like fluorescence peaks declined significantly, while the intensity of humic-like fluorescence peak increased significantly in DOM. Vermicomposting process might change the compositions of DOM with elevated concentrations of humic acid and fulvic acid in the organics. In all, this study suggested the suitability of 3DEEM for monitoring the organics transformation and assessing the maturity in the vermicomposting.

The acaricidal activity of Adonis coerulea extracts was investigated against Psoroptes cuniculi. The aqueous, methanol, acetic ether and petroleum ether extracts all showed marked acaricidal activity in vitro. Especially, the acetic ether extract possessed strong toxicity against mites in vitro with LT50 values 0.743 h, 2.730 h, 5.919 h and 22.536 h at concentrations of 500, 250, 125 and 62.5 mg/ml, respectively. At the same time, the acetic ether extract showed the best effectiveness topically to infested rabbits in vivo. After three times treatment, at the day 20, rabbits treated with A. coerulea extract were observed only small scabs or secretions in ear canal, but no mites. These findings suggested that as a potential insecticide, A. coerulea should be studied further to develop active components or a new acaricidal drug.

RESUMO

Taking the ginseng in Xiao Xing' an Mountains of Northeast China as test object, this paper studied the effects of applying Streptomyces pactum (Act12) on ginseng growth and on the soil microflora in root zone and root surface. After treated with Act12, the yield and quality of ginseng' s medicinal part improved, the induced enzyme activities in leaves and the root activity increased, and the numbers and proportions of soil bacteria and actinomycetes increased significantly while those of soil fungi decreased. Compared with the control, the soil microflora in treatment Act12 changed. The numbers of the dominant bacteria Pseudomonas fluorescens, Pseudomonas koreensis, and Microbacterium oxydans were much higher in root zone soil and root surface soil, and the pathogen Plectosphaerella cucumerina decreased in root zone soil and disappeared in root surface soil. These results suggested that the addition of Act12 could improve the soil microflora, enhance the resistance and root activity of ginseng plant, and increase the ginseng yield and its quality.

RESUMO

OBJECTIVE: To screen the main component of Dahuangzhechong pill's anti-arterial thrombosis with the orthogonal design and refine Dahuangzhechong pills. METHODS: In accordance with the orthogonal design table (L(16)2(15)), divided herbs into 16 groups and made the appropriate liquid. The liquid was gave to SD rats by intragastric administration,the model group, normal control group received the same volume of physiological saline. Isolated rats' carotid artery after intragastric administration a week,modeled according to ferric chloride inducement the carotid artery thrombosis method, then collected blood, detected content of platelet, thromboxane B2 (TXB2) and 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha), sheared and measured dry weight of the modeling artery, then placed arteries in 10% formalin fixation, observed morphological changes in vascular tissue by HE staining. RESULTS: Pathological examination revealed: each experimental group had thrombosis, softening, dissolution, absorption, and intimal injury, but the severity of thrombosis were diferent. Orthogonal analysis showed: 1, influence on dry weight of thrombus: rhubarb, ground beetle, leeches, peach seed, dry paint, except dry paint P<0.05, the others P<0.01.2, influence on plasma 6- keto-PGF1alpha level: peach seed, dry paint, ground beetle, gadfly, grubs, leeches, rhubarb, except rhubarb P<0.05, the others P<0.01.3, influence on plasma TXB2: ground beetle, peach seed, dried paint, rhubarb, leeches, except leech P<0.05, the others P<0.01.4, influence on platelet count: peach seed, dry paint, rhubarb, ground beetle, gadfly, leeches, except gadfly, leeches P<0.05, the others P<0.01. CONCLUSION: Anti-artery thrombosis of Dahuangzhechong Pill is most closely related with rhubarb, ground beetle, leeches, peach seed, dry paint and gadfly.

RESUMO

Traditional Chinese patent medicines (TCPMs) are widely used for treatment of chronic hepatitis B (CHB) in China. To estimate the overall effectiveness of TCPMs for CHB, we performed a systematic review of clinical reports designed as randomized controlled trials (RCTs). One hundred and thirty-eight available RCTs and quasi-RCTs on 62 TCPMs, involving 16,393 patients, were included. The methodological quality of these trials was generally "poor". Few trials (6.52%) reported the methods of randomization correctly. Another common problem was the lack of allocation concealment, proper blinding, and the reporting of lost cases and dropouts. Forty-two trials (30.43%) on 27 TCPMs reported some anti-viral effect of TCPMs. Others reported beneficial aspects, including improvements of liver function (79.71% of the studies), liver fibrosis (29.99%), and CHB symptoms (92.75%). Forty-one articles (29.71%) reported mild adverse events with TCPMs but these occurred infrequently. In summary, the outcome of the report on currently registered TCPMs may be biased due to poor methodology. The data from these trials, therefore, is too weak to use in forming a recommendation for treatment of CHB. Nevertheless, five drugs (Dan Shen agents, Da Huang Zhe Chong pill/capsule, Shuang Hu Qing Gan granule, Fu Zheng Hua Yu granule and Cao Xian Yi Gan capsule) appear to be more effective than the other TCPMs.

RESUMO

OBJECTIVE: To investigate the effect of Dahuangzhechong pill on the gene expression spectra of preventing arterial thrombosis, and reveal its mechanism on molecule level. METHODS: Mononuclear cell and blood platelet of the arterial thrombosis patients were separated before and after treatment by Dahuangzhechong pill. Their RNA was extracted respectively and the genes expressions were detected using gene array containing 14,000 gene. RESULTS: 44 genes up-expressed and 299 genes down-expressed in blood platelet, 252 genes expression increased and 299 genes expression decreased in mononuclear cell genes after treated with Dahuangzhechong pill. The cluster analysis showed that the genes contained ion channel and transport protein, apoptosis related protein, DNA synthesis, repair and transcription factor, cell receptor, cell signal and transducin, and protein translation and synthesis, etc. CONCLUSION: Dahuangzhechong pill may prevent arterial thrombosis through genes containing ion channel and transport protein, apoptosis related protein, DNA synthesis, repair and transcription factor, cell receptor, cell signal and transducin, and protein translation and synthesis, etc.

RESUMO

OBJECTIVE: To observe the clinical therapeutic effect of combination of Source Point and Back-Shu Point on perimenopausal syndrome, and provide a new thought of therapy for perimenopausal syndrome. METHODS: Eighty cases of perimenopausal syndrome were randomly divided into a combination of Source Point and Back-Shu Point group and a routine acupuncture group, 40 cases in each group. The combination of Source Point and Back-Shu Point group was treated with acupuncture at Taixi (KI 3), Taichong (LR 3), Taibai (SP 3), Sanyinjiao (SP 6), Shenshu (BL 23), Ganshu (BL 18), Pishu (BL 20), Guanyuan (CV 4); and the routine acupuncture group was treated with acupuncture at Baihui (GV 20), Guanyuan (CV 4), Shenshu (BL 23), Taixi (KI 3), San-yinjiao (SP 6). The Kupperman score and the changes of serum estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH) were observed before and after treatment in the two groups. RESULTS: The total effective rate of 92.5% in the combination of Source Point and Back-Shu Point group was superior to 80.0% in the routine acupuncture group, with a significant difference (P < 0. 05); the Kupperman score of 24. 85 +/- 8.35 in the combination of Source Point and Back-Shu Point group was significantly decreased as compared with 35.38 +/- 9.83 in the routine acupuncture group (P < 0.05) after treatment; the contents of E2, FSH and LH in the combination of Source Point and Back-Shu Point group were significantly improved after treatment, and with a significant difference compared to the routine acupuncture group (P < 0.01, P < 0.05). CONCLUSION: Combination of Source Point and Back-Shu Point has a benign regulation function for E2, FSH and LH, and can significantly improve the Kupperman score, is superior to routine acupuncture for perimenopausal syndrome.
