温针对肌筋膜痛扳机点模型大鼠病理形态及致痛性炎性介质的影响

目的:在建立扳机点大鼠模型的基础上用温针进行干预,通过显微病理技术及微透析技术,评价其对扳机点模型大鼠病理形态及致痛炎性介质的影响。方法:将64只SD雄性大鼠随机分为A组(空白对照)、B组(模型对照)和C组(模型干预);A、B每组又分3小组(A0,A1,A2和B0,B1,B2),C组分为2小组(C1,C2)。B、C两组建立MTr Ps模型,造模成功后并分别给予C1组7 d和C2组15 d温针干预。分批处死大鼠,MTr Ps局部取材,制片后进行苏木精-伊红染色,光镜下观察其病理变化,通过微透析技术对大鼠动物模型扳机点局部白细胞介素-1β和前列素E2进行检测。结果:镜下可见,造模组的肌纤维排列紊乱、断裂、扭曲,局部肌纤维纤维化、挛缩增粗等;局部可见有巨噬细胞等炎症细胞侵入及挛缩结节部位出现大面积粘连,温针干预后局部肌纤维的病理状态明显改善,局部微小血管形成和成熟,局部肌纤维修复。在造模成功后,进行温针干预前B0组的白细胞介素-1β和前列素E2的量明显高于A0组(P0.01),通过7d的温针干预,C1和B1组白细胞介素-1β和前列素E2的量差异无统计学意义(P0.05),C1、B1组明显高于A1组(P0.01);通过15d温针干预,C2组的白细胞介素-1β和前列素E2的量低于B2组(P0.05),但C2、B2组明显高于A2组(P0.01),C2组的白细胞介素-1β及前列素E2的量低于C1组(P0.05)。结论:运动联合击打的造模方式通过病理组织学证实是有效的;温针能够改善大鼠肌筋膜痛扳机点局部肌纤维的病理状态及炎症状态,促进局部微小血管形成和成熟,有助于扳机点局部肌纤维修复。     

Cutaneous mastocytosis associated with a mixed germ cell tumour of the ovary: report of a case and review of the literature

A 10-year-old girl with a mixed germ cell tumour of the ovary, treated by surgery and chemotherapy, developed cutaneous mastocytosis approximately 8 months after starting chemotherapy. This is the sixth report of a germ cell tumour associated with mastocytosis. c-kit receptor point mutations, including Asp816Val and Val560Gly were absent in a biopsy specimen obtained from lesional skin.

Evidence for Dry Needling in the Management of Myofascial Trigger Points Associated With Low Back Pain: A Systematic Review and Meta-Analysis

Objective

To evaluate the current evidence of the effectiveness of dry needling of myofascial trigger points (MTrPs) associated with low back pain (LBP).

Detection of c-Ki- ras point mutation from pancreatic juice

Summary Cytological diagnosis of pancreatic carcinoma sometimes poses difficulties in distinguishing malignant from benign cells. Recent molecular study of pancreatic carcinoma has revealed a very high incidence of a point mutation of the c-Ki-ras oncogene at codon 12 in this neoplasm. To take advantage of this technique for the diagnosis of pancreatic carcinoma, we attempted to amplify the c-Ki-ras gene from endoscopically obtained pancreatic juice by isolation of DNA and polymerase chain reaction (PCR) coupled with restriction fragment length polymorphism (RFLP). PCR was possible in approx 70% of the cases. A point mutation was nonradioisotopically detected in 4 of 6 pancreatic carcinomas and in one intraductal papillary neoplasm, whereas no mutation was detected in other cases. Thus, this method was thought to be useful for the diagnosis of pancreatic carcinoma.     

The effect of GB21 acupressure on pain intensity in the first stage of labor in primiparous women: A randomized controlled trial

IntroductionLabor pain is one of the most intensive pains experienced by women; it results in physical, emotional, and physiological changes in women’s body. The present study aimed to examine the effect of GB21 acupressure on labor pain.DesignIn this randomized clinical trial, 174 primiparous women in their first stage of labor were selected and assigned to three groups: GB21 acupressure group (n = 58), sham group (n = 58), and control group (n = 58).InterventionsThe acupressure and sham groups received routine labor care and acupressure in three different phases of cervical dilations to 3−5 cm, 6−7 cm, and 8−10 cm. The control group received routine care in labor.Main outcome measuresPain severity was measured using a pain scale ruler in three cervical dilations before and after intervention. The collected data were analyzed using the ANOVA, Kruskal–Wallis, paired-t test and Mann–Whitney tests.ResultsPain reduction was significantly higher in GB21 groups compared with sham and control groups (P = 0.001). No statistically significant difference was observed between the three groups in terms of delivery outcomes.ConclusionsIn this study, GB21 acupressure was effective in pain relief during labor, hence recommended as a practical, effective, inexpensive, and accessible method for labor pain management.
