RESUMO

Sclerotinia sclerotiorum is a necrotrophic plant pathogenic fungus with broad distribution and host range. Bioactive compounds derived from plant extracts have been proven to be effective in controlling S. sclerotiorum. In this study, the mycelial growth of S. sclerotiorum was effectively inhibited by maleic acid, malonic acid, and their combination at a concentration of 2 mg/mL, with respective inhibition rates of 32.5%, 9.98%, and 67.6%. The treatment of detached leaves with the two acids resulted in a decrease in lesion diameters. Interestingly, maleic acid and malonic acid decreased the number of sclerotia while simultaneously increasing their weight. The two acids also disrupted the cell structure of sclerotia, leading to sheet-like electron-thin regions. On a molecular level, maleic acid reduced oxalic acid secretion, upregulated the expression of Ss-Odc2 and downregulated CWDE10, Ss-Bi1 and Ss-Ggt1. Differently, malonic acid downregulated CWDE2 and Ss-Odc1. These findings verified that maleic acid and malonic acid could effectively inhibit S. sclerotiorum, providing promising evidence for the development of an environmentally friendly biocontrol agent.

RESUMO

Invariant natural killer T (iNKT) cells develop from CD4+CD8+ double-positive (DP) thymocytes and express an invariant Vα14-Jα18 T-cell receptor (TCR) α-chain. Generation of these cells requires the prolonged survival of DP thymocytes to allow for Vα14-Jα18 gene rearrangements and strong TCR signaling to induce the expression of the iNKT lineage-specific transcription factor PLZF. Here, we report that the transcription factor Yin Yang 1 (YY1) is essential for iNKT cell formation. Thymocytes lacking YY1 displayed a block in iNKT cell development at the earliest progenitor stage. YY1-deficient thymocytes underwent normal Vα14-Jα18 gene rearrangements, but exhibited impaired cell survival. Deletion of the apoptotic protein BIM failed to rescue the defect in iNKT cell generation. Chromatin immunoprecipitation and deep-sequencing experiments demonstrated that YY1 directly binds and activates the promoter of the Plzf gene. Thus, YY1 plays essential roles in iNKT cell development by coordinately regulating cell survival and PLZF expression.

RESUMO

Qianlie Tongqiao Capsule (QTC) is clinically confirmed to be efficacious and safe in treating lower urinary tract syndromes and bladder dysfunction that are induced by benign prostatic hyperplasia (BPH). However, the functional mechanisms of QTC remain unclear. We aim to investigate the effects of QTC on both bladder weight and several growth factors in the bladder tissue of rats with testosterone-induced BPH. BPH in the rats was established through bilateral orchiectomy and subcutaneous administration of testosterone propionate (5 mg/kg) dissolved in corn oil. At the end of the study, all bladder tissues were collected and weighed, and a histological examination was conducted using H&E staining. Immunohistochemistry and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) were applied to detect the expression of nerve growth factor (NGF), basic fibroblast growth factor (bFGF), and transformation growth factor-ß1 (TGF-ß1) in the bladder tissue. The expression of Bcl-2 and Bax in the bladder tissue was tested by Western Blot and qRT-PCR. We found that QTC, especially when administered in high-dosages, had a significant inhibitory effect on bladder weight gain and overexpression of NGF, bFGF, and TGF-ß1 in rats with BPH. In addition, QTC downregulated and upregulated protein and mRNA expression of Bcl-2 and Bax in the bladder after prostatic obstruction, respectively. Furthermore, QTC balanced the Bcl-2/Bax ratio. Overall, these results reveal possible functional mechanisms of QTC in treating BPH-caused bladder dysfunction, and further studies are needed.

RESUMO

BACKGROUND: We systematically reviewed randomized controlled trials (RCTs) of complementary and alternative interventions for fatigue after traumatic brain injury (TBI). METHODS: We searched multiple online sources including ClinicalTrials.gov, the Cochrane Library database, MEDLINE, CINAHL, Embase, the Web of Science, AMED, PsychINFO, Toxline, ProQuest Digital Dissertations, PEDro, PsycBite, and the World Health Organization (WHO) trial registry, in addition to hand searching of grey literature. The methodological quality of each included study was assessed using the Jadad scale, and the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. A descriptive review was performed. RESULTS: Ten RCTs of interventions for post-TBI fatigue (PTBIF) that included 10 types of complementary and alternative interventions were assessed in our study. There were four types of physical interventions including aquatic physical activity, fitness-center-based exercise, Tai Chi, and aerobic training. The three types of cognitive and behavioral interventions (CBIs) were cognitive behavioral therapy (CBT), mindfulness-based stress reduction (MBSR), and computerized working-memory training. The Flexyx Neurotherapy System (FNS) and cranial electrotherapy were the two types of biofeedback therapy, and finally, one type of light therapy was included. Although the four types of intervention included aquatic physical activity, MBSR, computerized working-memory training and blue-light therapy showed unequivocally effective results, the quality of evidence was low/very low according to the GRADE system. CONCLUSIONS: The present systematic review of existing RCTs suggests that aquatic physical activity, MBSR, computerized working-memory training, and blue-light therapy may be beneficial treatments for PTBIF. Due to the many flaws and limitations in these studies, further controlled trials using these interventions for PTBIF are necessary.

RESUMO

OBJECTIVE: To evaluate the effect and safety of Yimusake Tablets combined with dapoxetine hydrochloride and either of them used alone in the treatment of premature ejaculation (PE). METHODS: We randomly assigned 180 PE patients to oral medication of Yimusake Tablets at 1.5 g per night (group A), dapoxetine hydrochloride at 30 mg at 1-3 hours before anticipated sexual activity (group B), the Yimusake Tablets plus dapoxetine hydrochloride simultaneously (group C), all for 8 weeks. After 4 and 8 weeks of medication, we recorded and compared the changes in the intravaginal ejaculation latency time (IELT), measures of the PE profile (PEP), and adverse events among the three groups of patients. RESULTS: The treatment was accomplished and complete data obtained from 154 of the patients, 56 in group A, 52 in group B, and 46 in group C. After 4 and 8 weeks of medication, the mean IELT was dramatically prolonged in all the three groups as compared with the baseline (P<0.01), most significantly at 8 weeks in group C (ï¼»2.08±0.68ï¼½ min), followed by B (ï¼»1.76±0.52ï¼½ min) and A (ï¼»1.47±0.44ï¼½ min), with statistically significant differences among the three groups (P<0.01). The PEP measures were remarkably improved in group A at 8 weeks (P<0.05), and both in B and C at 4 and 8 weeks (P<0.05), most significantly at 8 weeks in group C (P<0.05), in which the patients scored 1.96±0.77 in perception of control over ejaculation, 2.62±0.98 in satisfaction with sexual intercourse, 3.04±0.62 in PE-related distress, and 3.57±0.80 in PE-induced difficult relationship with their partners, all markedly improved as compared with groups A and B (P<0.05). Adverse reactions were observed in 2 cases (3.6%) in group A, 6 cases (9.6%) in B, and 5 cases (10.9%) in C. No severe adverse events occurred in any of the patients during the study. CONCLUSIONS: Combined medication of Yimusake Tablets and dapoxetine hydrochloride, with its advantages of effectiveness and safety, deserves to be recommended for the treatment of PE.

RESUMO

OBJECTIVE: To establish a nurse based post-marketing safety surveillance model for traditional Chinese medicine injections (TCMIs). METHOD: A TCMIs safety monitoring team and a research hospital team engaged in the research, monitoring processes, and quality control processes were established, in order to achieve comprehensive, timely, accurate and real-time access to research data, to eliminate errors in data collection. RESULT: A triage system involving a study nurse, as the first point of contact, clinicians and clinical pharmacists was set up in a TCM hospital. Following the specified workflow involving labeling of TCM injections and using improved monitoring forms it was found that there were no missing reports at the ratio of error was zero. CONCLUSION: A research nurse as the first and main point of contact in post-marketing safety monitoring of TCM as part of a triage model, ensures that research data collected has the characteristics of authenticity, accuracy, timeliness, integrity, and eliminate errors during the process of data collection. Hospital based monitoring is a robust and operable process.

RESUMO

OBJECTIVE: To explore the correlation between the Traditional Chinese Medicine (TCM) syndrome differentiation and urodynamic parameters in benign prostate hyperplasia (BPH). METHODS: Urodynamic examination was conducted for 152 BPH patients, who were divided by TCM syndrome differentiation into seven types, namely, kidney-yin deficiency, kidney-yang deficiency, aqueduct stagnancy, spleen-qi deficiency, lung-heat and qi stagnancy, wetness-heat down-flow and phlegm-wetness stagnancy. RESULTS: Of the total number of the BPH cases, 71 (46.71%) were differentiated as the type of kidney-yang deficiency, 40 (26.31%) as aqueduct stagnancy, and 14 (9.21%) as kidney-yin deficiency. Fifty-eight cases of Grade III-IV bladder outflow obstruction fell into the type of kidney-yang deficiency, and another 38 cases of the same grade along with 26 cases of Grade V-VI came under the type of aqueduct stagnancy. Of the 12 patients with very weak contractility of detrusor urine, 4 (33.33%) were attributed to the type of kidney-yang deficiency and 7 (58.33%) the type of aqueduct stagnancy. Among the 48 with weak contractility of detrusor urine, 27 (56.25%) fell under the type of kidney-yang deficiency and 17 (35.42%) the type of aqueduct stagnancy. CONCLUSION: The TCM syndrome differentiation of BPH is correlated with bladder outflow obstruction and detrusor urine contractility, which has provided corresponding evidence for the quantization and objectification of the TCM syndrome differentiation of BPH.
