RESUMO

OBJECTIVE: To explore the demographic and disease-related factors associated with acupuncture response in patients with chronic tension-type headache (CTTH). METHODS: Using data from a randomized clinical trial (218 cases) consisting of 4 weeks of baseline assessment, 8 weeks of treatment, and 24 weeks of follow-up, participants were regrouped into responders (at least a 50% reduction in monthly headache days at week 16 compared with baseline) and non-responders. Twenty-three demographic and disease-related factors associated with acupuncture response in 183 participants were analyzed by multivariable logistic regression. RESULTS: One hundred and nineteen (65.0%) participants were classified as responders. Four factors were significantly independently associated with acupuncture response, including treatment assignment, headache intensity at baseline, and 2 domains [general health (GH) and social functioning (SF)] from the 36-Item Short Form Health Survey quality of life questionnaire. Treatment assignment was associated with non-response: participants receiving true acupuncture were 3-time more likely to achieve a CTTH response than those receiving superficial acupuncture [odds ratio (OR) 0.322, 95% confidence interval (CI) 0.162 to 0.625, P=0.001]. Compared with patients with mild-intensity headache, patients with moderate-intensity headache were twice as likely to respond to acupuncture (OR 2.001, 95% CI 1.020 to 4.011, P=0.046). The likelihood of non-response increased by 4.5% with each unit increase in the GH grade (OR 0.955, 95% CI 0.917 to 0.993, P=0.024) while decreased by 3.8% with each unit increase in the SF grade (OR 1.038, 95% CI 1.009 to 1.069, P=0.011). CONCLUSIONS: Greater headache intensity, lower GH score, and higher SF score were associated with better acupuncture responses in CTTH patients. These 3 factors require independent validation as predictors of acupuncture effectiveness in CTTH.

RESUMO

Six new cytochalasans-namely, aspergicytochalasins A-F (1-6)-together with five known analogs were isolated and characterized from the endophytic fungus Aspergillus sp. from the medicinal plant Lonicera japonica. The structures of the new compounds were established by NMR and MS methods as well as single crystal X-ray diffractions. Compounds 3 and 4 showed weak antibacterial activities to Staphylococcus aureus, with MIC values of 128 and 64 µg/mL, respectively. Compounds 1, 3, 5 and 6 showed inhibitory activities on NO production, with IC50 values less than 40 µM.

RESUMO

Background: Acupuncture has been extensively applied to manage irritable bowel syndrome (IBS) in clinical practice in China. Some randomized controlled trials (RCTs) have demonstrated their efficacy, but it has rarely been compared with first-line antispasmodics to verify their effectiveness. Therefore, we compare acupuncture with antispasmodics in the treatment of IBS by using an adjusted indirect treatment comparison meta-analysis. Methods: Embase, OVID Medline, and the Cochrane Central Register of Controlled Trials databases were searched from inception to 14 March 2022, with no language restrictions. RCTs comparing antispasmodics or acupuncture with placebo or one of the antispasmodics were enrolled. The primary outcome of interest was the improvement of abdominal pain. And the secondary outcomes of interest were the relief of global IBS symptoms and adverse events. The random-effects model was utilized to pool data. The effect size was measured by standardized mean difference (SMD) or relative ratio, and the effectiveness of acupuncture and different antispasmodics were ranked by P-scores. Results: Thirty-five RCTs (n = 5,190) were included. The analysis showed that cimetropium, drotaverine, acupuncture, and pinarverium were superior over placebo in relieving abdominal pain; cimetropium (SMD, -3.00 [95%CI, -4.47 to -1.53], P-score = 0.99) ranked the most effective. In pairwise comparisons, acupuncture had a greater improvement than most antispasmodics except cimetropium and drotaverine in relieving abdominal pain, although the between-group difference was statistically insignificant. In the analysis of continuous outcome in the relief of global IBS symptoms, the result showed that pinaverium was more effective (SMD, 1.72 [95%CI, 0.53 to 2.92], P-score = 0.90) than placebo. Trimebutine and acupuncture had greater improvements than placebo, but no significant difference was shown between groups. In pairwise comparisons, acupuncture was more effective than pinaverium (SMD, -1.11 [95%CI, -1.94 to -0.28]) in relieving global IBS symptoms. In the analysis of adverse events, acupuncture had a lower adverse event rate than most of the other antispasmodics. Conclusion: Cimetropium, drotaverine, and acupuncture were all better than placebo in improving abdominal pain. Acupuncture was preferred over pinaverium in relieving global IBS symptoms, and acupuncture had lower adverse events than most antispasmodics.

RESUMO

BACKGROUND AND AIMS: The pathological mechanism of irritable bowel syndrome (IBS) is unclarified, which commonly leads to unresponsiveness to conventional treatments. The diagnostic criteria for refractory IBS are not clearly defined. We performed a systematic review to summarize the key points of the definition of refractory IBS in different studies. We also conducted a meta-analysis to explore whether the diverse definitions for refractory IBS affect the therapeutic effect of gut-directed hypnotherapy (GDH). METHODS: We searched OVID Medline, Embase and Cochrane (until September 2020) for randomized controlled trials (RCTs) recruiting patients with refractory IBS. We evaluated the definition of refractory IBS through the following aspects: duration of symptoms, unresponsive to dietary intervention, lifestyle modification, pharmacology, psychology, severity assessment and adequate explanation. The effect of the different definitions for refractory IBS on the therapeutic effect of gut-directed hypnotherapy (GDH) was checked by a meta-analysis. RESULTS: Twenty-one RCTs were finally included. Six (28.6%) out of 21 RCTs recruited patients with symptoms lasting for over 12 months; 8 (38.1%) RCTs reported a prior use of dietary intervention; 1 (4.8%) RCT reported the use of lifestyle modification; 11 (52.4%) RCTs recruited patients who were unresponsive to pharmacology; 2 (9.5%) RCTs recruited patients with no response to psychological therapy ; 5 (23.8%) RCTs had symptoms severity assessment; and 8 (38.1%) RCTs recruited patients who were informed adequately. Despite being tested in trials with heterogeneous definition of refractory IBS, GDH had similar effectiveness when compared with supportive treatment [standardized mean difference (SMD)=-0.69, 95%CI: -0.93 to -0.44)] or waiting-list control (SMD=-0.54, 95%CI: -0.98 to -0.10). CONCLUSIONS: Varied definitions in refractory IBS were common phenomena in clinical studies. Resistance to symptom severity assessment and psychological treatments should be more explicitly defined. Gut-directed hypnotherapy was efficacious for refractory IBS and was not affected by the diversity in the definition of refractory IBS among RCTs.

RESUMO

BACKGROUND: Chinese herbal medicine (CHM) is gaining popularity in treating irritable bowel syndrome (IBS). Although its efficacy was shown in recent randomized controlled trials (RCTs), it is rarely compared with antispasmodics to confirm its effectiveness. We aimed to resolve this uncertainty through a network meta-analysis. METHODS: We searched for RCTs that compared CHM or antispasmodics with placebo or one of them in the treatment of IBS. The primary outcomes were adequate relief of global IBS symptoms and abdominal pain. The data were pooled using a random-effects model. The effect size measure was pooled relative risk (RR), and treatments were ranked according to their P-scores. KEY RESULTS: We included 57 RCTs (n = 8869). After completion of treatment, drotaverine, individual CHM, otilonium, cimetropium, standard CHM, and pinaverium were efficacious in adequate relief of global IBS symptoms, and drotaverine ranked the first (RR, 2.33 [95% CI, 1.31-4.14], P-score =0.91); no difference was found between these treatments. After completion of treatment, drotaverine, standard CHM, pinaverium, and individual CHM were efficacious in abdominal pain, and drotaverine ranked the first (RR, 2.71 [95% CI, 1.69-4.36], P-score =0.91); no difference was found between these treatments. Standard CHM had significantly more adverse events than placebo (RR, 1.82 [95% CI, 1.12-2.94]) and other treatments. CONCLUSIONS: CHM and antispasmodics were efficacious for improvement of global IBS symptoms and abdominal pain. The adverse events of CHM were higher than antispasmodics; however, the heterogeneity of CHM formulas and the very low quality of the evidence warrants further investigation.

RESUMO

BACKGROUND: Botulinum neurotoxin A (BoNT-A) was the primary choice for preventive treatment of chronic migraine. Topiramate and acupuncture showed promising effect for chronic migraine, but their effectiveness relative to BoNT-A was rarely studied. We aimed to perform a network meta-analysis to compare the effectiveness and acceptability between topiramate, acupuncture, and BoNT-A. METHODS: We searched OVID Medline, Embase, the Cochrane register of controlled trials (CENTRAL), the Chinese Clinical Trial Register, and clinicaltrials.gov for randomized controlled trials (RCTs) that compared topiramate, acupuncture, and BoNT-A with any of them or placebo in the preventive treatment of chronic migraine. A network meta-analysis was performed by using a frequentist approach and a random-effects model. The primary outcomes were reduction in monthly headache days and monthly migraine days at week 12. Acceptability was defined as the number of dropouts owing to adverse events. RESULTS: We included 15 RCTs (n = 2545). Eleven RCTs were at low risk of bias. The network meta-analyses (n = 2061) showed that acupuncture (2061 participants; standardized mean difference [SMD] -1.61, 95% CI: -2.35 to -0.87) and topiramate (582 participants; SMD -0.4, 95% CI: -0.75 to -0.04) ranked the most effective in the reduction of monthly headache days and migraine days, respectively; but they were not significantly superior over BoNT-A. Topiramate caused the most treatment-related adverse events and the highest rate of dropouts owing to adverse events. CONCLUSIONS: Topiramate and acupuncture were not superior over BoNT-A; BoNT-A was still the primary preventive treatment of chronic migraine. Large-scale RCTs with direct comparison of these three treatments are warranted to verified the findings.

RESUMO

BACKGROUND: Soybean oil is a complex mixture of five fatty acids (palmitic, stearic, oleic, linoleic, and linolenic). Soybean oil with a high oleic acid content is desirable because this monounsaturated fatty acid improves the oxidative stability of the oil. To investigate the genetic architecture of oleic acid in soybean seeds, 260 soybean germplasms from Northeast China were collected as natural populations. A genome-wide association study (GWAS) was conducted on a panel of 260 germplasm resources. RESULTS: Phenotypic identification results showed that the oleic acid content varied from 8.2 to 35.0%. A total of 2,311,337 single-nucleotide polymorphism (SNP) markers were obtained. GWAS analysis showed that there were many genes related to oleic acid content with a contribution rate of 7%. The candidate genes Glyma.11G229600.1 on chromosome 11 and Glyma.04G102900.1 on chromosome 4 were detected in a 2-year-long GWAS. The candidate gene Glyma.11G229600.1 showed a positive correlation with the oleic acid content, and the correlation coefficient was 0.980, while Glyma.04G102900.1 showed a negative correlation, with a coefficient of - 0.964. CONCLUSIONS: Glyma.04G102900.1 on chromosome 4 and Glyma.11G229600.1 on chromosome 11 were detected in both analyses (2018 and 2019). Glyma.04G102900.1 and Glyma.11G229600.1 are new key candidate genes related to oleic acid in soybean seeds. These results will be useful for high-oleic soybean breeding.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Osteoking is a Traditional Chinese Medicine consisting of seven types of medicinal herbs originated from Yi nationality and has been used in clinic to treat bone diseases for thousands of years in China. Osteoking shows excellent clinical therapeutic effects on osteoporosis, but it is not clear whether Osteoking could exhibit beneficial effects against osteoporosis via reducing reactive oxygen species (ROS). AIM OF THE STUDY: To explore whether the protective effects of Osteoking on osteoporosis related to ROS, we investigated the effects of Osteoking on osteogenesis differentiation under oxidative stress. MATERIALS AND METHODS: The ovariectomized (OVX) osteoporosis model was established by ovarian surgery, and Osteoking was orally administrated for 84 days. Then the pathogenesis changes of femur were analyzed by Hematoxylin and eosin (H&E) and Masson's trichrome staining. The levels of ROS, malondialdehyde (MDA)and superoxide dismutase (SOD) from rats' serum were further measured. In vitro, mouse pre-osteoblastic MC3T3-E1 cells pre-treated with or without 0.25 mM tert-butyl hydroperoxide (t-BHP) for 2 h were cultured and treated with different dilutions of Osteoking or 20 µM N-Acetyl-L-cysteine for another 24 h, respectively. The intracellular ROS production and markers of oxidative damage of the MC3T3-E1 cells were determined using corresponding kits, respectively. The expressions of alkaline phosphatase (ALP), collagen type I, osteoprotegerin (OPG), TGF-ß1, ß-catenin, receptor activator of nuclear factor-κB ligand (RANKL) and interleukin-6 (IL-6) were further analyzed by qRT-PCR and western blotting upon treatment. RESULTS: Our results showed that Osteoking significantly improving trabecular microstructure by promoting collagen fiber repair and new bone or cartilage regeneration was demonstrated in OVX osteoporosis rat models by micro-CT analysis and histological staining results. Osteoking supplementation reduced the levels of ROS and MDA in OVX rat serum and increased SOD activities. In addition, Osteoking could also up-regulate the proteins expression levels of Runx2, osteocalcin (BGP) and osteoprotegerin (OPG) but reducing the expression of tartrate-resistant acid phosphatase (TRAP). In vitro, Osteoking could effectively inhibit the t-BHP-induced intracellular excessive ROS production and protect cells from oxidative stress in mouse pre-osteoblastic MC3T3-E1 cells. Meanwhile, the mRNA expressions of ALP, collagen type I, OPG, TGF-ß1 and ß-catenin were also up-regulated whereas the RANKL and IL-6 were down-regulated in Osteoking-treated MC3T3-E1 cells. CONCLUSIONS: A novel therapeutic mechanism of Osteoking on osteoporosis reveals by present investigation. Clinic effects of Osteoking to treat osteoporosis are closely related to its ability to reduce oxidative stress.

RESUMO

INTRODUCTION: Non-pharmacological treatments are used in the management of irritable bowel syndrome, and their effectiveness has been evaluated in multiple meta-analyses. The robustness of the results in the meta-analyses was not evaluated. We aimed to assess whether there is evidence of diverse biases in the meta-analyses and to identify the treatments without evidence of risk of bias. METHODS AND ANALYSIS: We will search MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and CINAHL Plus for meta-analyses that evaluate the effectiveness of non-pharmacological treatments. The time of publication will be limited from inception to December 2018. The credibility of the meta-analyses will be evaluated by assessing between-study heterogeneity, small-study effect and excess significance bias. The between-study heterogeneity will be assessed using the Cochrane's Q test, and the extent of the heterogeneity will be classified using the I2 statistics. The existence of a small-study effect in a meta-analysis will be evaluated using the funnel plot method and confirmed by Egger's test. Excess significance bias will be evaluated by comparing the expected number of clinical studies with positive findings with the observed number. ETHICS AND DISSEMINATION: No formal ethical approval is required since we will use publicly available data. We will disseminate the findings of the umbrella review through publication in a peer-reviewed journal and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42018111516.

RESUMO

BACKGROUND: Pain after hemorrhoidal surgery bothers both clinicians and patients. Somatosensory stimulation treatments have shown promising effect on the pain after hemorrhoidal surgery, but the comparative effectiveness between them has not been studied. We aim to determine the relative effectiveness among these treatments on pain relief after hemorrhoidal surgery by using network meta-analysis. METHOD: We will search the following electronic databases: MEDLINE, EMBASE, the Cochrane library, Chinese Biomedicine database (CBM), China National Knowledge Infrastructure (CNKI). We will include randomized controlled trials (RCTs) that examine the effect of somatosensory stimulation treatments on pain after hemorrhoidal surgery. The primary outcome will be the responder rate after treatment. The secondary outcomes will include the assessments with pain intensity scales (visual analog scale, numeric rating scale, or other scales) on day 1 to 7 after surgery. Two independent reviewers will extract needed information from eligible trials using standardized electronic forms. Network meta-analysis will be performed using a frequentist framework based on electrical network theory. The relative effectiveness of the treatments will be ranked by using P score, which is the mean probability of a treatment ranking the best in all treatments. Meta-regression will be performed to assess the impact of surgery type, anesthesia methods, and funding source on the treatment ranking. The quality of the eligible RCTs will be evaluated by the Cochrane risk of bias tool. ETHICS AND DISSEMINATION: The result of this network meta-analysis will clarify which is the relatively best somatosensory-stimulation treatment in relieving postoperative pain caused by hemorrhoidal surgery, and the review will, therefore, guide the management of postoperative pain after hemorrhoidal surgery for clinicians and patients. This review does not require ethical approval and will be reported in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: PROSPERO CRD42018115558.

RESUMO

Chimeric antigen receptor-modified T cells (CAR-T cells) have emerged as a promising cancer immunotherapy for solid tumors. Epithelial cell adhesion molecule (EpCAM) is overexpressed in a variety of tumors and is recognized as a biomarker for circulating tumor cells and cancer stem cells, representing an attractive target for adoptive T-cell immunotherapy. This study generated third-generation CAR-T cells with redirected specificity to EpCAM (EpCAM CAR-T) by lentiviral vector. The study demonstrated that EpCAM CAR-T cells can elicit lytic cytotoxicity to target cells in an EpCAM-dependent manner and secrete cytotoxic cytokines, including interferon gamma and tumor necrosis factor alpha. Furthermore, adoptive transfer of EpCAM CAR-T cells significantly delayed tumor growth and formation in xenograft models. In addition, the safety evaluation showed that CAR-T cells have no systemic toxicity in mice. The data confirmed the antitumor ability and safety of CAR-T cells targeting EpCAM and may provide a new target for CAR-T cell therapies in treating solid tumors.

RESUMO

BACKGROUND: Nonscar wound healing is a desirable treatment for cutaneous wounds worldwide. Peptide OH-CATH30 (OH30) from king cobra can selectively regulate the innate immunity and create an anti-inflammatory micro-environment which might benefit nonscar wound healing. PURPOSE: To overcome the enzymatic digestion and control release of OH30, OH30 encapsulated in carboxymethyl chitosan nanoparticles (CMCS-OH30 NP) were prepared and their effects on wound healing were evaluated. METHODS: CMCS-OH30 NP were prepared by mild ionic gelation method and properties of the prepared CMCS-OH30 NP were determined by dynamic light scattering. Encapsulation efficiency, stability and release profile of OH30 from prepared CMCS-OH30 NP were determined by HPLC. Cytotoxicity, cell migration and cellular uptake of CMCS-OH30 NP were determined by conventional methods. The effects of prepared CMCS-OH30 NP on the wound healing was investigated by full-thickness excision animal models. RESULTS: The release of encapsulated OH30 from prepared CMCS-OH30 NP was maintained for at least 24 h in a controlled manner. CMCSOH30 NP enhanced the cell migration but had no effects on the metabolism and proliferation of keratinocytes. In the full-thickness excision animal models, the CMCS-OH30 NP treatment significantly accelerated the wound healing compared with CMCS or OH30 administration alone. Histopathological examination suggested that CMCS-OH30 NP promoted wound healing by enhancing the granulation tissue formation through the re-epithelialized and neovascularized composition. CMCS-OH30 NP induced a steady anti-inflammatory cytokine IL10 expression but downregulated the expressions of several pro-inflammatory cytokines. CONCLUSION: The prepared biodegradable drug delivery system accelerates the healing and shows better prognosis because of the combined effects of OH30 released from the nanoparticles.

RESUMO

Pinus koraiensis polysaccharides (PKP) were extracted by hot water from P. koraiensis pine cones. Five polysaccharide fractions named PKP-A, PKP-B, PKP-C, PKP-D and PKP-E were successfully separated at final ethanol concentrations of 30%, 50%, 60%, 70% and 80%, respectively. HPLC, FT-IR, GC-MS and automatic amino-acid analysis were applied to investigate their chemical characteristics. Monosaccharide component analysis indicated that the five fractions were all composed of D-ribose, L-rhamnose, L-arabinose, D-xylose, D-mannose, D-glucose and D-galactose, but their molar ratios were quite different. HPLC results revealed that the polysaccharides precipitated by higher concentrations of ethanol solution had lower molecular masses. Moreover, the antioxidant activities of the five fractions were studied on the basis of hydroxyl radical and ABTS radical scavenging tests. The five graded polysaccharide fractions exhibited good inhibitory power, and MTT tests in vitro showed the IC50 of PKP-A and PKP-E were 1,072.5 and 2,070.0 µg · mL-1, respectively. These results demonstrated that the PKP could be a potential source of natural antioxidants or dietary supplements.

RESUMO

BACKGROUND: The incidence of menopausal anxiety and depression is increasing. It can induce and aggravate a variety of somatic symptoms. Despite of the good effects of psychotropic drugs on the disease, patients' compliance is poor. Therefore, it is necessary to find a drug which is practical, effective, and easy for patients to take. OBJECTIVE: To evaluate the efficacy of Wuling Capsule (WC), a Chinese herbal medicine, in treatment of female climacteric syndrome with depression and anxiety state. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: A total of 96 outpatients of female climacteric syndrome from Department of Gynecology of Integrated Traditional Chinese and Western Medicine, Huashan Hospital, Fudan University, Department of Gynecology of Traditional Chinese Medicine, Longhua Hospital, Shanghai University of Traditional Chinese Medicine, and Department of Traditional Chinese Medicine, Obstetrics and Gynecology Hospital, Fudan University were included. The study was designed as a randomized, positive drug parallel controlled trial. The patients were divided into WC group (64 cases) and control group (32 cases) and were orally administered Wuling Capsule and Gengnianan Tablet, respectively. MAIN OUTCOME MEASURES: The efficacy was evaluated with Kupperman menopausal index (KMI), Self-rating Depression Scale (SDS), and Self-rating Anxiety Scale (SAS) before treatment, and after 3-week and 6-week treatment. RESULTS: The total response rate was 89.66% (52/58) in the WC group, which was superior to that in the control group [76.67% (23/30)]. Ridit test showed that there was a significant difference between the two groups (P<0.05). Kupperman score of the two groups decreased markedly after the treatment (P<0.01), but there was no statistical difference between the two groups. The scales of SAS and SDS in both groups were improved obviously after the treatment (P<0.01). Covariance analysis showed that the decrease of SAS score in the WC group was more significant than that in the control group after 3- and 6-week treatment (P<0.05, P<0.01), but the SDS score was improved more significantly in the WC group than in the control group after 6-week treatment (P<0.05). CONCLUSION: Both Wuling Capsule and Gengnian' an Tablet are effective in treating female climacteric patients with depression and anxiety state. Wuling Capsule is more effective to alleviate depression and anxiety as compared with Gengnianan Tablet.
