背景:滞动针治疗肌筋膜疼痛综合征的镇痛效果显著,但镇痛机制尚不明确。目的:探索滞动针干预激痛点缓解肌筋膜疼痛综合征疼痛的作用机制。方法:按照随机数字表法将54只SD大鼠随机分为空白组(n=16)和造模组(n=38),造模组采用“打击结合离心运动”方式制备左侧股内侧肌筋膜疼痛综合征模型,造模12周后随机挑选6只验证造模成功,将剩余32只造模大鼠随机分为模型组(n=16)与滞动针组(n=16),使用滞动针对滞动针组大鼠左侧股内侧肌局部激痛点进行干预治疗,2次/周,治疗4周。造模前后及治疗后进行左足机械缩足阈值测定;治疗后第4周,苏木精-伊红染色观察大鼠左侧股内侧肌肌肉组织形态学变化,ELISA法检测血清和中脑导水管周围灰质中P物质、β-内啡肽水平,免疫组化检测中脑导水管周围灰质中小胶质细胞标志物(Iba-1)和c-fos阳性表达,Western Blot检测中脑导水管周围灰质脑源性神经营养因子蛋白表达。结果与结论:①与空白组比较,造模后模型组、滞动针组大鼠机械缩足阈值降低(P<0.05);治疗4周后,滞动针组大鼠机械缩足阈值高于模型组(P<0.05);②苏木精-伊红染色结果显示,模型组肌纤维排列紊乱、粗细不等,肌细胞增大并出现核内移现象,细胞内出现圆形挛缩结节以及紧张带;滞动针组肌纤维排列整齐,肌细胞多呈角状,细胞内偶见挛缩结节;③与空白组比较,模型组血清中P物质水平升高(P<0.05),血清中β-内啡肽及脑中P物质、β-内啡肽水平均降低(P<0.05);与模型组比较,滞动针组血清中P物质水平降低(P<0.05),血清中β-内啡肽及脑中P物质、β-内啡肽水平均升高(P<0.05);④与空白组比较,模型组c-fos、Iba-1阳性表达及脑源性神经营养因子蛋白均升高(P<0.05);与模型组比较,滞动针组c-fos阳性表达升高(P<0.05),Iba-1阳性表达及脑源性神经营养因子蛋白均降低(P<0.05);(5)结果表明,滞动针可能通过抑制中脑导水管周围灰质小胶质细胞的活性、下调脑源性神经营养因子蛋白表达间接促进小胶质细胞向M2表型极化释放β-内啡肽、增加c-fos神经元兴奋性,从而降低中枢致敏程度,有效缓解肌筋膜疼痛综合征疼痛的症状。

The Luoguhe intrusion, located in MoheCounty, Heilongjiang Province, is mainly composed of mon-zogranite, quartz diorite and granodiorite, with minor dio-rite, tonalite, quartz monzodiorite, quartz monzonite, syeno-granite and alkali-feldspar granite. The intrusion can bedivided into two lithological units, i.e. quartz diorite andmonzogranite units, with affinities to high-K calc-alkalineseries. The quartz diorite unit (SiO2: 54.79%―58.30%Na2O/CaO: 0.79―1.53 and Shand index: 0.77―0.82) belongsto metaluminous rocks. And the monzogranite unit (SiO2:65.29%―66.45%, Na2O/CaO: 1.73―3.43 and Shand index<1.05) can be considered as weakly peraluminous rocks. Theintrusion is characterized by high REE abundance (∑REE =180.2―344.3 μg/g), medium-strong negative Eu anomalies(δ Eu = 0.33―0.82), weak REE fractionation [(La/Yb)N =4.12―10.45], enrichments in Rb, Th, U, K, La, Ce, Nd, HfZr and Sm, but strong depletions of Ba, Nb, Ta, Sr, P and TiThese characteristics of major, REE and trace elements in-dicate that the intrusion was formed in a transitional tectonicsetting from compressional to extensional regime, which canbe classified as post-collisional granitoids. SHRIMP U-Pbzircon analyses yield ages of 517±9 and 504±8 Ma for thequartz diorite and monzogranite units, respectively. The dis-covery of Early Paleozoic post-collisional granites in thenorthern margin of the Erguna massif indicates that thenorthern branch of Paleo-Asian Ocean between Siberianplate and Erguna massif was closed in the Early Paleozoicand the Salair orogeny ended ca. 500 Ma ago.

A transparent radiative cooling(T-RC)film with low transmittance in solar spectra and selectively high emissivity in the atmospheric window(8-13𝜇m)is applied on roof glazing for building energy *** evaluate the per-formance of the T-RC film,two identical model boxes(1.0 m×0.6 m×1.2 m,L×W×H)were constructed and the inside air temperatures were measured in August in Ningbo,*** show that the maximum temperature difference between the two model boxes with and without the T-RC film was 21.6℃during the experiment.A whole building model was built in EnergyPlus for the model *** a good agreement achieved between the calculation results and the measured temperature data,the experimentally validated EnergyPlus model was then extended to an 815.1 m^(2)exhibition building with roof glazing to analyze the annual air conditioning(AC)energy *** results show that by incorporating both the T-RC film’s cooling benefit in summer and heating penalty in winter,the annual AC energy consumption of the exhibition building can be reduced by 40.9-63.4%,varying with different climate conditions.
