Abstract

: Background: Myofascial pain syndrome (MPS) is a painful musculoskeletal condition. The prevalence of MPS ranges from 5.9% to 38.7% in the general population. "Thor-ra-nee-san-tha-kat" (TRK) is a traditional formula included in the Thailand National List of Essential Medicines for the treatment for muscle pain caused by abdominal rigidity and for severe constipation. Objectives: The authors employed a pilot single-blind, randomized-controlled trial to compare the effectiveness of TRK and naproxen for the treatment of chronic upper trapezius MPS. Materials and Methods: Seventy-six male and female subjects, ages 25-55 years, who met the inclusion criteria were equally randomized into two groups to receive either two 500 mg capsules of TRK once daily before bed or two 250 mg naproxen tablets twice a day after meals for 14 days. Subjects assessed their level of pain using the numerical rating scale. Cervical range of motion (CROM) was determined using a goniometer, and pressure pain threshold (PPT) was assessed using an algometer. Adverse drug reactions were recorded and all items were compared within and between groups, before and after treatment. Results: The results revealed that patient pain scores after 14 days of treatment were much improved with mean differences exceeding the reference minimum clinically important difference (MCID) in both groups. However, the changes in CROM and PPT values were small and did not surpass their respective reference MCIDs except for the right lateral bending CROM for naproxen treatment. The adverse drug reactions were mild, with watery stools reported by 47% of patients in the TRK-treated group and constipation reported by 24% of those in the naproxen group. Conclusion: The administration of TRK formula for 14 days was safe and as effective as naproxen at providing short-term relief of pain in patients with chronic upper trapezius pain.

摘要

: 背景: 肌筋膜疼痛综合征 (MPS) 是一种疼痛的肌肉骨骼疾病。MPS在普通人群中的患病率为5.9% 至38.7%。“Thor-ra-nee-san-tha-kat” (TRK) 是泰国国家基本药物清单中包含的传统配方,用于治疗腹部僵硬引起的肌肉疼痛和严重便秘。 目标: 作者采用了一项试验性单盲随机对照试验,比较TRK和萘普生治疗慢性上斜方肌MPS的有效性。 材料与方法: 符合纳入标准的76名年龄在25-55岁的男性和女性受试者被随机分为两组,分别在睡前每天一次接受两次500 mg TRK胶囊,或在饭后每天两次接受两次250 mg萘普生片,持续14天。受试者使用数字评定量表评估他们的疼痛水平。使用测角仪测定颈椎运动范围 (CROM),并且使用algameter评估压痛阈值 (PPT)。记录两组患者治疗前后药物不良反应发生情况,并进行组内、组间比较。 结果: 结果显示,治疗14天后的患者疼痛评分大大改善,两组中的平均差异超过参考最小临床重要差异 (MCID)。然而,CROM和PPT值的变化很小,除了萘普生治疗的右侧向弯曲CROM之外,没有超过它们各自的参考mcid。不良反应轻微,TRK治疗组47% 的患者报告水样便,萘普生组24% 的患者报告便秘。 结论: 在慢性上斜方肌疼痛患者中,TRK配方给药14天是安全的,并且在提供短期疼痛缓解方面与萘普生一样有效。

METHODS::The ATP binding-cassette superfamily corresponds the mostly transmembrane transporters family found in humans. These proteins actively transport endogenous and exogenous substrates through biological membranes in body tissues, so they have an important role in the regulation of many physiological functions necessary for human homeostasis, as well as in response regulation to several pharmacological substrates. The development of multidrug resistance has become one of the main troubles in conventional chemotherapy in different illnesses including cancer, being the increased efflux of antineoplastic drugs the main reason for this multidrug resistance, with a key role of the ABC superfamily. Likely, the interindividual variability in the pharmacological response among patients is well known, and may be due to intrinsically factors of the disease, genetic and environmental ones. Thus, the understanding of this variability, especially the genetic variability associated with the efficacy and toxicity of drugs, can provide a safer and more effective pharmacological treatment, so ABC genes are considered as important regulators due to their relationship with the reduction in pharmacological response. In this review, updated information about transporters belonging to this superfamily was collected, the possible role of these transporters in cancer, the role of genetic variability in their genes, as well as some therapeutic tools that have been tried to raise against main transporters associated with chemoresistance in cancer.

METHODS:BACKGROUND:Cholinergic neurotransmission regulates neuroinflammation in Parkinson disease (PD). RESEARCH DESIGN AND METHODS:The authors conducted a delayed-start study of donepezil for cognitive decline in non-demented PD patients. The study consisted of a 96-week randomized placebo-controlled double-blind phase 1, followed by a 24-week donepezil extension phase 2. The primary outcome measure was a change in the Mini-Mental State Examination (MMSE) at week 120. RESULTS:A total of 98 patients were randomly allocated to the early-start (donepezil-to-donepezil) and delayed-start (placebo-to-donepezil) groups. Mean (SD) of the baseline MMSE was 27.6 (2.0) and 28.0 (2.1), respectively. MMSE change at week 120 was better in the early-start group than in the delayed-start group, but the difference was not significant. The MMSE declined in apolipoprotein ε4 carriers, but not in non-carriers, and the factor interaction (intervention × ε4 genotype) was highly significant (P < 0.001). Analyzed with the interaction, the difference was significant (group difference 1.95 [0.33 to 3.57], P = 0.018). The MMSE decline slope in phase 1 was significantly better in the early-start group than in the delayed-start group (P = 0.048). CONCLUSIONS:Cognitive function deteriorated in ε4 carriers, but not in non-carriers, and early-start donepezil may postpone cognitive decline in the former.

METHODS::Since the discovery of dental pulp stem cells, a lot of teams have expressed an interest in dental pulp regeneration. Many approaches, experimental models and biological explorations have been developed, each including the use of stem cells and scaffolds with the final goal being clinical application in humans. In this review, the authors' objective was to compare the experimental models and strategies used for the development of biomaterials for tissue engineering of dental pulp with stem cells. Electronic queries were conducted on PubMed using the following terms: pulp regeneration, scaffold, stem cells, tissue engineering and biomaterial. The extracted data included the following information: the strategy envisaged, the type of stem cells, the experimental models, the exploration or analysis methods, the cytotoxicity or viability or proliferation cellular tests, the tests of scaffold antibacterial properties and take into account the vascularization of the regenerated dental pulp. From the 71 selected articles, 59% focused on the "cell-transplantation" strategy, 82% used in vitro experimentation, 58% in vivo animal models and only one described an in vivo in situ human clinical study. 87% used dental pulp stem cells. A majority of the studies reported histology (75%) and immunohistochemistry explorations (66%). 73% mentioned the use of cytotoxicity, proliferation or viability tests. 48% took vascularization into account but only 6% studied the antibacterial properties of the scaffolds. This article gives an overview of the methods used to regenerate dental pulp from stem cells and should help researchers create the best development strategies for research in this field.
