Lignans-Rich Extract from Herpetospermum caudigerum Alleviate Physical Fatigue in Mice

Objective

To ascertain anti-fatigue constituents and mechanisms of Herpetospermum caudigerum.

Methods

The 80% ethanol extracts of Herpetospermum caudigerum were partitioned with chloroform, ethyl acetate and n-butanol, respectively. Male Kunming mice were divided into 13 groups with 16 mice in each group: a control group fed with water, 9 groups treated with 3 fractions of Herpetospermum caudigerum (chloroform fraction, ethyl acetate fraction and n-butanol fraction) at dose of 80, 160 and 320 mg/kg for the low-dose group, medium-dose group and high-dose group, 3 herpetrione (HPE) treated groups fed with HPE at dose of 15, 30, and 60 mg/kg for the low-dose group, medium-dose group and high-dose group. All animals were treated once per day for 30 days. Anti-fatigue activity was assessed through the forced swimming test and serum biochemical parameters including blood lactic acid (BLA), blood urea nitrogen (BUN), malondialdehyde (MDA), hepatic glycogen (HG), lactic dehydrogenase (LDH), superoxide dismutase (SOD) and glutathione peroxidase (GPx) determined following the recommended procedures provided by the commercial kits.

Results

Compared with the control group, the lignans extract (ethyl acetate fraction) of Herpetospermum caudigerum and HPE could signifificantly prolonged the exhaustive swimming time (P<0.05 or P<0.01), and also increased the HG levels (P<0.05 or P<0.01) and the activities of antioxidant enzymes (SOD, GPx and LDH, P<0.05 or P<0.01); BLA and MDA levels were decreased considerably in lignans extract and HPE treated groups (P<0.05 or P<0.01). HPE also could significantly decrease the BUN contents compared with the control group (P<0.05). The chloroform and n-butanol fraction showed no effect on swimming time and biochemical parameters.

Conclusions

The lignans extract had antifatigue activities and HPE may be partly responsible for the anti-fatigue effects of Herpetospermum caudigerum. The possible mechanisms of anti-fatigue activity were related to the decrease of BUN and BLA, the increase of the HG storage and protecting corpuscular membrane by preventing lipid oxidation via modifying several enzyme activities.

     

Potent Therapeutic Effects of Shouwu Jiangqi Decoction(首乌僵芪汤)on Polycystic Ovary Syndrome with Insulin Resistance in Rats

Objective:To investigate the effect of Shouwu Jiangqi Decoction(首乌僵芪汤,SJD) on polycystic ovary syndrome(PCOS) with insulin resistance(IR) in rats and to explore the underlining molecular mechanisms.Methods:A total of 51 female Sprague-Dawley rats were randomly divided into 6 groups:control group(n=7),model group(n=8),SJD high-dose group(n=9),SJD medium-dose group(n=9),SJD low-dose group(n=9) and DMBG group(n=9).Radioimmunoassay was used to measure serum follicle-stimulating hormone(FSH),luteinizing hormone(LH) and testosterone concentrations and qRT-PCR and western blot were used to examine the expression levels of mRNA and protein respectively of insulin receptor substrate 1(IRS-1)and phosphatidylinositide 3-kinases(PI3K) p85α in different groups.Results:FSH level significantly decreased in the model group compared with the normal control(P0.01),and high-dose SJD and DMBG can significantly increase FSH level(P0.01).LH level showed a mild increase without statistic significance in the model group compared with the control and different dosages of SJD had no significance effect on LH level,while DMBG can significantly decrease LH level(P0.01).Testosterone level significantly increased in the model group compared with the control group(P0.01),and high-dose SJD and DMBG can significantly decrease testosterone level(P0.01).The expression of IRS-1 as well as PI3Kp85α were significantly decreased in the model group compared with the normal control group at both mRNA(P0.001) and protein(P0.01) level,and both high-dose SJD and DMBG can enhance IRS-1 and PI3 K expression(P0.05).Conclusions:SJD has potent therapeutic effects on PCOS with IR in rats.The therapeutic effects of SJD on IR and ovulatory dysfunction are probably achieved through correcting the defective insulin signaling transduction.

Objective: To determine the effect of propolis on Candida albicans and to compare it with the effects of some other herbal extracts and antibiotics on this pathogenic fungi. Methods: The extracts of propolis, Thymus vulgaris, Caryophillium aromaticus, Echinophora platyloba, Allium cepa and Cinnamomum zeylanicum were prepared and the antifungi effects of the extracts were examined on Candida albicans ATCC10231 using disc-diffusion assay and micro-broth dilution. The minimum fungicidal concentration (MFC) and minimum inhibitory concentrations (MIC) as well as inhibition zone were evaluated and the anti fungi effects of herbal extracts were compared with amphotricin B and nystatin at the times of 24, 48 and 72 h. Data analysis was performed using t test. Results: Obtained results showed that propolis extract with MIC90 and MFC equal to 39 and 65 μg/mL, respectively, possess the highest antifungal activity when compared with other studied extracts. The extracts of Allium cepa and Thymus vulgaris, with MFC of 169 and 137 μg/mL, respectively, showed the lowest effects on the fungi. Also nystatin and amphotricin B yielded better effects on the tested fungi compared with the effects of all studied extracts on Candida albicans. Conclusions: Propolis extract is effective in controlling Candida albicans. However, the issue requires further investigation on samples in animals and performing toxicological examinations.     

Association of Platelet-Activating Factor Receptor Gene rs5938 (G/T) and rs313152 (T/C) Polymorphisms with Coronary Heart Disease and Blood Stasis Syndrome in A Chinese Han Population

Objective

To explore the association of the platelet-activating factor receptor (PAFR) gene rs5938, rs313152 and rs76744145 polymorphisms with coronary heart disease (CHD) and blood stasis syndrome (BSS) of CHD in Chinese Han population.

Methods

A total of 570 CHD patients (299 with BSS and 271 with non-BSS) and 317 controls were enrolled. The PAFR gene rs5938, rs313152 and rs76744145 polymorphisms were genotyped using the multiplex SNaPshot technology. The statistical analysis was conducted using a multiple variable logistic regression model.

Results

Significant differences were detected in the genotypes frequency distributions of the rs5938 (P<0.01), but not the rs313152 (P>0.05), between the controls and CHD patients. Individuals with an rs5938 or rs313152 mutated allele had a low risk for CHD [adjusted odds ratio (aOR)=0.35, 95% confidence interval (CI): 0.23 to 0.56, P<0.01; aOR=0.65, 95% CI: 0.46 to 0.91, P<0.05, respectively]. After the CHD patients were stratified as BSS or non-BSS according to their Chinese medicine patterns, the rs5938 polymorphism mutated alleles had a significant association with a low risk for BSS of CHD (aOR=0.32, 95% CI: 0.18 to 0.57, P<0.01) and non-BSS of CHD (aOR=0.31, 95% CI: 0.17 to 0.55, P<0.01). The rs313152 polymorphism was associated with a low risk for BSS (aOR=0.51, 95% CI: 0.33 to 0.79, P<0.01), but not for non-BSS (aOR=1.22, 95% CI: 0.81 to 1.85, P<0.05). Furthermore, the interaction effect of the rs5938 and rs313152 polymorphisms for BSS of CHD was significantly based on an aOR value associated with the combination of the rs5938 GT genotype with the rs313152 TC genotype of 0.27 (95% CI: 0.1 to 0.7, P<0.01).

Conclusion

The PAFR gene rs5938 or rs313152 polymorphisms might be a potential biomarker for susceptibility to CHD, especially to BSS of CHD in Chinese Han population.

     

Effect of Poria cocos Hydroethanolic Extract on Treating Adriamycin-Induced Rat Model of Nephrotic Syndrome

Objective: To evaluate the effect of Poria cocos (Schw.) Wolf hydroethanolic extract (PHE) against nephrotic syndrome (NS) in rats and to identify the potential active components from PHE. Methods: The high content compounds were isolated and purified by using column chromatography followed by preparative high-performance liquid chromatography (p-HPLC). Forty male Wistar rats with adriamycin (ADR)-induced NS were randomly divided into 5 groups, 8 in each group: model control group, positive control group (with prednisone treatment), PHE low-dose group, PHE middle-dose group and PHE high-dose group. Another 8 rats were recruited as vehicle control group. All rats received the intragastric administration of corresponding drugs or saline for 30 days. During the experimental period, rats'' behavior and appearance were observed and recorded daily, and their body weights were recorded weekly. After treatment, 24-h urine samples were collected to evaluate the urine protein and urine creatinine (Ucr); then the rats were sacrificed to collect carotid blood and to determine the levels of serum total protein (TP), albumin (Alb), globulin (Glo), total cholesterol (TC) and cytokine interlukin-4 (IL-4). Results: Six acidic components were isolated and identified from the PHE section: pachymic acid, 15α-hydroxydehydrotumulosic acid, trametenolic acid, dehydropachymic acid, 3β-hydroxy-lanosta-7,9(11), 24-trien-21-oic-acid and dehydroeburicoic acid. Compared with the model control group, the urine protein content were significantly decreased in the PHE treatment groups and positive control group (P<0.05), especially PHE middle-dose group (P<0.01). The Ucr values and serum levels of TP, Glo, TC and IL-4 in PHE low- and middle-dose groups were also presented obvious recover tendency as compared with the model control group (P<0.05 or P<0.01). However, positive control group and all PHE groups indicated no significant therapeutic effect on raising Alb value, although PHE low- and middle-dose treatment groups showed better outcomes than positive control group (P>0.05). Conclusions: PHE showed an encouraging therapeutic effect against ADR-induced NS in a rat model. PHE might be a group of effective substances for the treatment of NS.

Objective:To investigate the effects of Shenfu Injection(参附注射液,SFI) on cerebral metabolism in a porcine model of cardiac arrest(CA).Methods:Thirty Wuzhishan minipigs were randomly assigned to the control group(n=6),epinephrine group(EP group,n=12) and SFI group(n=12).After8 min of untreated ventricular fibrillation(VF),pigs in the EP group or SFI group were administered with either EP(0.02 mg/kg) or SFI(1.0 mL/kg),respectively.After successful resuscitation,cerebrospinal fluid(CSF) levels of glucose,pyruvate,lactate,glutamate and glycerol were measured at 1,6,12 and 24 h after recover from spontaneous circulation(ROSC).In addition,neurologic deficit score(NDS) was calculated at 24 h after ROSC.Surviving pigs were killed at 24 h after ROSC,and the brain tissue was obtained for ultra-microstructure examination.Results:Compared with the EP group,CSF glucose and pyruvate levels were higher(all P0.01),and lactate levels were lower in the SFI group(P0.01).Meanwhile,CSF glutamate and glycerol levels in the SFI group were lower in comparison to the EP group(all P0.05).In addition,SFI decreased NDS at 24 h after ROSC(P0.01),and alleviated the histopathological damage of the brain.Conclusions:SFI could alleviate brain injury after CA,which may be associated with improving cerebral metabolism.     

Protective Effects of Xiongshao Capsule (芎芍胶囊) on Anti-inflammatory Function of High-Density Lipoprotein in An Atherosclerosis Rabbit Model

Objective: To observe the effects of Xiongshao Capsule(芎芍胶囊, XSC) on anti-inflammatory properties of high-density lipoprotein(HDL), myeloperoxidase(MPO) and paraoxonase 1(PON1) in serum of atherosclerosis(AS) rabbit model and explore the anti-inflammatory protective effects of XSC on HDL. Methods: Sixty rabbits were randomized into the control, the model, XSC low-, medium-and high-dose(Rhizoma Chuanxiong + Radix Paeoniae rubra : 0.6+0.3, 1.2+0.6, 2.4+1.2 g·kg-1·day-1, respectively), and simvastatin(1 g·kg-1·day-1) groups. The model rabbits were fed with high-fat diet and respective drugs for 15 weeks. The blood and thoracic aortas samples were collected at the end of 15 weeks. The levels of serum MPO and PON1 as well as total cholesterol(TC) and free cholesterol(FC) in aorta wall cells were tested by enzyme linked immunosorbent assay. Results: TC and FC in the model group were significantly higher than those in the control group(P0.01). Compared with the model group, TC and FC in the XSC groups were significantly lower(P0.05 or P0.01), so was simvastatin group(P0.01). There was no significant difference in PON1 level between groups(P0.05), even between model and control groups(P0.05). The serum MPO level in the model group was significantly higher than that in the control group(P0.05), which was significantly lower in XSC groups as well as simvastatin group(P0.05 or P0.01), and no difference was found between XSC groups and simvastatin group(P0.05). Conclusions: XSC can reduce the serum MPO level in AS rabbits to protect the anti-inflammatory function of HDL, maintaining the normal lipid transport function. TC and FC levels in aorta cells decline, and this process initiated by XSC plays an anti-AS role.     

Effect of Kuanxiong Aerosol(宽胸气雾剂)on Patients with Angina Pectoris:A Non-inferiority Multi-center Randomized Controlled Trial

Objective: To evaluate the effect and safety of Kuanxiong Aerosol(宽胸气雾剂, KA) on patients with angina pectoris. Methods: Block randomization was performed to randomly allocate 750 patients into KA(376 cases) and control groups(374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA(0.6 m L per spray). The control group received 1 sublingual nitroglycerin tablet(NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment(1, 2, 3, 4, 5, and 5 min). Logistic regression analysis was performed to observe the factors influencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society(CCS) classes of angina. Results: The 5-min remission rates in the KA and control groups were not significantly different(94.41% vs. 90.64%, P0.05). The angina CCS class significantly influenced the rate of remission (95% confidence interval = 0.483–0.740, P0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSⅠ and Ⅳ subgroups(P0.05), while they were significantly better for KA in the CCSⅡ and Ⅲ subgroups(P0.05 or P0.01). Furthermore, the incidence of adverse reactions was significantly lower in the KA group than in the control group for the CCSⅡ and Ⅲ subgroups(9.29% vs. 26.22%, 10.13% vs. 20.88%, P0.05 or P0.01). Conclusions: KA is not inferior to NT in the remission of angina. Furthermore, in CCSⅡ and Ⅲ patients, KA is superior to NT, with a lower incidence of adverse reactions.     

In Vivo and In Vitro Anti-inflammatory Effects of Ethanol Fraction from Periploca forrestii Schltr.

Objective: To determine the anti-inflammatory effects of an ethanol fraction of Periploca forrestii Schltr. (EFPF) and to investigate the potential mechanisms underlying in vivo and in vitro models. Methods: The anti-inflammatory effects of EFPF were evaluated using the xylene-induced mouse ear edema and carrageenan-induced rat paw edema models in vivo. In vitro, RAW264.7 cells were exposed to 0–800 μg/mL EFPF and the cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Then cells were treated with different concentrations of EFPF (100–400 μg/mL) and stimulated with lipopolysaccharide (LPS, 1 μg/mL) for 24 h. The supernatant was analyzed for nitric oxide (NO) using the Griess reagent, and the levels of inflammatory mediators and cytokines were determined using enzyme-linked immunosorbent assays for prostaglandin E2 (PGE2), tumor necrosis factor α (TNF-α), interleukin (IL) 6, and IL-10. The protein expressions of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor κB (NF-κB), and mitogen-activated protein kinases (MAPKs) including extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and p38 MAPK were examined by Western blot. Results: Compared with the control group, EFPF significantly reduced mouse ear edema and rat paw edema rate (P<0.05 or P<0.01). Compared with the LPS group, EFPF significantly inhibited the LPS-stimulated production of NO, PGE2, TNF-α and IL-6 (P<0.05 or P<0.01), and increased the IL-10 production (P<0.05). EFPF also significantly inhibited LPS-induced protein expressions of iNOS and COX-2, suppressed the phosphorylation and degradation of inhibitor of NF-κB-α, decreased p65 level, and inhibited the phosphorylation of p38, ERK1/2 and JNK (P<0.05 or P<0.01). Conclusion: EFPF exerted anti-inflammatory effect by reducing protein expressions of iNOS and COX-2 and the production of the inflammation factors, including TNF-α, IL-6, NO and PGE2, mainly through inhibition of LPS-mediated stimulation of NF-κB and MAPK signaling pathways.     

Ginkgo Leaf Extract and Dipyridamole Injection as Adjuvant Treatment for Angina Pectoris: A Meta-Analysis of 41 Randomized Controlled Trials

Objective: To provide information about the effectiveness and safety of Ginkgo Leaf Extract and Dipyridamole Injection(GD) as one adjuvant therapy for treating angina pectoris(AP) and to evaluate the relevant randomized controlled trials(RCTs) with meta-analysis. Methods: RCTs concerning AP treated by GD were searched in China Biology Medicine Disc(SinoMed), PubMed, the China National Knowledge Infrastructure Database(CNKI), the Chinese Scientific Journals Database(VIP), Wanfang Database, Embase, and the Cochrane Library, from inception to February, 2017. The Cochrane Risk Assessment Tool was adopted to assess the methodological quality of the RCTs. The Review Manager 5.3 software was utilized to conduct the meta-analysis. Results: A total of 41 RCTs involving 4,462 patients were included in the meta-analysis. The results indicated that the combined use of GD and Western medicine(WM) against AP was associated with a higher total effective rate [risk ratio(RR)=1.25, 95% confidence interval(CI): 1.21–1.29, P0.01], total effective rate of electrocardiogram(RR=1.29, 95% CI: 1.21–1.36, P0.01). Additional, GD combined with WM could decrease the level of plasma viscosity [mean difference(MD)=–0.56, 95% CI: –0,81 to –0.30, P0.01], fibrinogen [MD=–1.02, 95% CI: –1.50 to –0.54, P0.01], whole blood low shear viscosity [MD=–2.27, 95% CI: –3.04 to –1.49, P0.01], and whole blood high shear viscosity(MD=–0.90, 95% CI: 1.37 to –0.44, P0.01). Conclusions: Comparing with receiving WM only, the combine use of GD and WM was associated with a better curative effect for patients with AP. Nevertheless, limited by the methodological quality of included RCTs more large-sample, multi-center RCTs were needed to confirm our findings and provide further evidence for the clinical utility of GD.     

Effects of Senegenin against Hypoxia/Reoxygenation-Induced Injury in PC12 Cells

Objective:To investigate the effect and the potential mechanism of Senegenin(Sen) against injury induced by hypoxia/reoxygenation(H/R) in highly differentiated PC12 cells.Methods:The cultured PC12 cells were treated with H/R in the presence or absence of Sen(60 μmol/L).Four groups were included in the experiment:control group,H/R group,H/R+Sen group and Sen group.Cell viability of each group and the level of lactate dehydrogenase(LDH) in culture medium were detected for the pharmacological effect of Sen.Hoechst 33258 staining and annexin V/propidium iodide double staining were used to analyze the apoptosis rate.Moreover,mitochondrial membrane potential(△Ψm),reactive oxygen species(ROS) and intracellular free calcium([Ca~(2+)]i) were measured by fluorescent staining and flow cytometry.Cleaved caspase-3and activity of NADPH oxidase(NOX) were determined by colorimetric protease assay and enzyme linked immunosorbent assay,respectively.Results:Sen significantly elevated cell viability(P0.05),decreased the leakage of LDH(P0.05) and apoptosis rate(P0.05) in H/R-injured PC12 cells.Sen maintained the value of△Ψm(P0.05) and suppressed the activity of caspase-3(P0.05).Moreover,Sen reduced ROS accumulation(P0.05) and[Ca~(2+)]i increment(P0.05) by inhibiting the activity of NOX(P0.05).Conclusion:Sen may exert cytoprotection against H/R injury by decreasing the levels of intracellular ROS and[Ca~(2+)]_i,thereby suppressing the mitochondrial pathway of cellular apoptosis.     

Chinese Medicine Yishen Jiangu Granules(益肾健骨颗粒)on Aromatase Inhibitor-Associated Musculoskeletal Symptoms

Objective: To assess the effectiveness of Yishen Jiangu Granules(益肾健骨颗粒, YSJGG) on aromatase inhibitor-associated musculoskeletal symptoms(AIMSS). Methods: A single-arm, open-label study was conducted in 34 postmenopausal women with breast cancer who experienced AIMSS. Patients were treated with YSJGG for 12 weeks(12.4 g orally twice daily). The primary outcome was a change in the mean worst pain score of Brief Pain Inventory-Short Form(BPI-SF) over 12 weeks, and the second outcomes included changes in pain severity and pain-related interference of BPI-SF and Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC), Modified Score for the Assessment of Chronic Rheumatoid Affections of the Hands(M-SACRAH), the Functional Assessment of Cancer Therapy-Breast(FACT-B), bone mineral density(BMD) and blood indices such as calcium(Ca), phosphate(P), and alkaline phosphatase(ALP). Results: Of 37 women recruited, 30 initiated the therapy and 24 were evaluable at 12 weeks. The primary outcome(BPI-SF worst pain scores) achieved a 2.17-point reduction compared with baseline(5.75±1.87 vs 3.58±2.15, P0.01). There were reductions in pain severity(decreased 1.65, P0.01) and pain-related interference(decreased 2.55, P0.01). The changes in WOMAC and M-SACRAH scores were similar to BPI-SF(P0.05). In the FACT-B, only physical wel-being and functional wel-being were improved compared with baseline(P0.05). No clinical differences were found in BMD, Ca, P and ALP. Conclusion: YSJGG is an effective and wel-tolerated agent to reduce AIMSS.

Objective

To investigate the antipyretic mechanism of Herba Ephedrae (Eph)-Ramulus Cinnamomi (RC) herb pair on yeast-induced pyrexia in rats.

Methods

Totally 30 qualified male SD rats were randomly assigned to the normal control (NC) group, the pyrexia model (model) group, the Eph, RC and Eph-RC treatment groups by a random digital table, 6 rats in each group. Each rat received a 20% aqueous suspension of yeast (10 mL/kg) except the NC group. The 3 treatment groups were administered 8.1, 5.4 and 13.5 g/kg Eph, RC and Eph-RC respectively at 5 and 12 h after yeast injection, the NC group and the model groups were administered equal volume of distilled water. Rectal temperatures were measured at 0, 6, 8, 10, 12, 15, 18, 24 and 30 h and urine was collected prior to yeast injection and at 6, 10, 18, 24, 30, and 36 h after yeast injection. Then urine metabolomic profiling by gas chromatography tandem mass spectrometry, coupled with multivariate statistical analysis and pattern recognition techniques were used to explore the antipyretic effects of Eph-RC. Partial least squares discriminate analysis was used to analyze the metabolomics dataset including classification and regression in metabolomics plot profiling.

Results

Compared with the NC group, rectal temperatures were significantly higher in the model group (P<0.01), while 3 treatment groups decreased significantly compared with the model group (P<0.05 or P<0.01). Rectal temperatures of Eph-RC-treated rats started to go down at 6 h, and markedly decreased at 8, 12, 15, 18 and 24 h (P<0.05 or P<0.01), while those of the Eph and RC groups had decreased firstly at 8 h and were markedly lower at 12 h (P<0.05 or P<0.01). Seventeen potential biomarkers related to pyrexia were confirmed and identified, including pyruvic acid, L-phenylalanine, L-tyrosine, phenylacetic acid, hippuric acid, succinic acid, citrate and so on. Eight potential alterations of metabolic pathways including phenylalanine metabolism, citrate cycle, tryptophan metabolism, biosynthesis of valine, leucine and isoleucine, were identified in relation to the antipyretic effects of Eph-RC using MetPA software.

Conclusion

The antipyretic effect of Eph-RC herb pair on yeast-induced pyrexia in rats involved correction of perturbed amino acid, fatty acid, and carbohydrate metabolism according to the metabolic pathway analysis with MetPA.

During treatment, the patients were interviewed quarterly, Kupperman Menopausal Index(KMI) scores, hot flush scores, insomnia scores, Menopause-Specific Quality of Life(MENQOL) scores and adverse effects were used for evaluating drug efficacy and safety respectively. The last interview was made at the end of 12-month treatment. Results: After treatment, KMI scores of HYKT group and HT group were both significantly decreased compared with baseline(P0.01) and there was no significant difference between groups(P0.05), except that KMI of HYKT group was higher after 3-month treatment(P0.05). After treatment, hot flush and insomnia scores were both improved significantly in two groups(P0.01); and HT had a better performance than HYKT in improving hot flush(P0.05). MENQOL were significantly improved in both groups after treatment(P0.01); but there was no significant difference between two groups(P0.05). The incidence of adverse event in the HYKT group was much lower than that in the HT group(P0.01). Conclusions: HYKT could effectively relieve PMSs and improve patient quality of life without severe adverse reactions. Although HYKT exerted curative effects more slowly than hormone, it possessed better safety profile than hormone.
