Effects of different directions of moxibustion therapy on hemorheology in rats with blood stasis due to cold retention

Objective

To investigate the effects of different directions of moxibustion therapy on hemorheology in rat models with blood stasis due to cold retention.

Methods

A total of 32 Wistar rats were randomly divided into 4 groups, based on the random digits table, including a normal group, a model group, a moxibustion along the meridian group, and a moxibustion against the meridian group, with 8 rats in each group. Except the normal group, the other 3 groups were used to make the rat models with blood stasis due to cold retention. Rats in the moxibustion along and against the meridian groups accepted moxibustion therapy in different directions on the trunk segment of the Bladder Meridian after successful modeling. Moxibustion for 10 min every day, and 7 d as a course of treatment. Two courses of treatment (a total of 14 d) were carried out. Quantitative score of signs and symptoms change was observed once a week, with a total of 7 times. Hemorheological indexes of rats were detected when the treatment finished.

Results

The quantitative scores of signs and symptoms in the model, moxibustion along the meridian and against the meridian groups were significantly higher than those in the normal group after modeling (P<0.05). When the treatment finished, the quantitative score of signs and symptoms in the model group was significantly higher than that in the normal group (P<0.05); the quantitative scores of signs and symptoms of rats in the moxibustion along and against the meridian groups were significantly lower than that in the model group (P<0.05); the quantitative score of signs and symptoms in the moxibustion along the meridian group was significantly lower than that in the moxibustion against the meridian group (P<0.05); the whole blood viscosity and erythrocyte aggregation index in the model group were significantly higher than those in the normal group (P<0.05), however the increases of erythrocyte hematocrit and erythrocyte sedimentation rate were not obvious (P>0.05); whole blood viscosity and erythrocyte aggregation index in the moxibustion along and against the meridian groups were significantly lower than those in the model group (P<0.05), while there were no statistically significant differences between the moxibustion along the meridian group and moxibustion against the meridian group (P>0.05).

Conclusion

Moxibustion along and against the meridian both showed different degrees of improvement for hemorrheology and symptoms of blood stasis due to cold retention. Improvement for symptoms of blood stasis due to cold retention was better in the moxibustion along the meridian group than that in the moxibustion against the meridian group. The influence on rat hemorrheology showed no significant difference between moxibustion along the meridian and moxibustion against the meridian.

     

破裂型椎间盘突出重吸收过程中P38MAPK信号通路的作用

目的 :构建大鼠自体尾椎破裂型椎间盘突出冲吸收动物模型,探讨P38丝裂原活化蛋白激酶(P38 mitogen-activated protein kinases,P38MAPK)信号通路在破裂型椎间盘突出重吸收中的作用。方法 :将40只3月龄SD大鼠随机分为对照组和实验组,每组20只。采用刺破大鼠自体尾椎椎间盘,包埋至L4-5背部肌肉的方法制作破裂型椎间盘突出重吸收模型。实验组从造模至取材之日予腹腔注射P38MAPK特异性阻断剂SB203580;对照组予腹腔注射生理盐水,分别在造模1周和4周后处死并取出包埋的椎间盘,电子天平称重。计算1周末和4周末椎间盘减少质量,镜下观察椎间盘形态退变情况。Real Time PCR法检测P38MAPK、肿瘤坏死因子α(tumour necrosis factor-α,TNF-α)、白细胞介素1β(interleukin-1β,IL-1β)、基质金属蛋白酶3(matrix metalloproteinase-3,MMP-3)、基质金属蛋白酶9(matrix metalloproteinase-9,MMP-9)的m RNA表达。Western Blot法检测TNF-α、IL-1β、MMP-3、MMP-9及磷酸化P38丝裂原活化蛋白激酶(phosphorylated p38mitogen-activated protein kinase,p-p38MAPK)的蛋白表达。结果 :实验组1周时椎间盘质量减小0.47±2.90mg,4周时减少1.11±3.05mg,两组之间无统计学差异(P0.05),对照组1周时椎间盘质量减小4.15±1.84mg,4周时减少10.56±3.29mg,两组之间存在统计学差异(P0.05)。镜下可见,实验组4周时与1周时相比,组织形态无明显退变,对照组4周时与1周时相比,组织形态出现明显退变。Real Time PCR检测,1周时,实验组椎间盘髓核组织中TNF-α、p38MAPK、MMP-3、MMP-9的m RNA表达低于对照组(P0.05);4周时,实验组TNF-α、IL-1β、p38MAPK、MMP-3的m RNA表达低于对照组(P0.05)。Western Blot法检测,4周时,实验组椎间盘组织中TNF-α、P38MAPK、P-p38MAPK、MMP-3的蛋白表达低于对照组(P0.05);对照组4周时椎间盘组织中TNF-α、IL-1β、P-p38MAPK的蛋白表达均高于1周时(P0.05)。对照组髓核组织中P-p38MAPK与MMP-3、IL-1β、TNF-α的蛋白表达呈正相关(0r1,P0.05)。结论 :P38阻断剂可能通过抑制髓核组织中P38MAPK的磷酸化,降低TNF-α、IL-1β、MMP-3、MMP-9的m RNA和蛋白体表达,从而抑制突出椎髓核组织重吸收。

219所医院脑心健康管理师工作开展和资源配置现况调查

目的了解中国脑心健康管理师工作开展和资源配置情况。为今后脑心健康管理师培养、工作开展及制定政策提供参考依据。方法2022年1—2月采用国家卫生健康委脑卒中防治工程委员会自行设计的“中国脑心健康管理师工作情况调查表”,通过线上发放调查问卷,以医院为单位对全国31个省、自治区、直辖市,具有获得国家卫生健康委脑卒中防治工程委员会认证的中国脑心健康管理师的医院进行调查。结果共调查219所医院,根据所在医院卒中中心等级划分为示范高级卒中中心14所、高级卒中中心95所、高级卒中中心建设单位39所、综合防治卒中中心8所、防治卒中中心10所、非脑卒中中心53所。根据是否为脑卒中筛查和干预项目基地医院划分为项目医院105所、非项目医院114所。项目医院和非项目医院在设立脑心健康管理师专职岗位、脑心健康管理师专职队伍规模人数构成比、脑心健康管理师团队(包括专职和兼职人员)规模数、脑心健康管理师出诊“脑卒中预防/筛查门诊”、出诊“卒中随访门诊”、举办质控会议、院外宣教受益数、出院患者随访和具备独立办公室上差异具有统计学意义(P<0.05)。不同卒中中心类型医院在是否承担项目工作、设立脑心健康管理师专职岗位、脑心健康管理师专职队伍规模、脑心健康管理师团队(包括专职和兼职人员)规模、脑心健康管理师出诊“脑卒中预防/筛查门诊”、出诊“卒中随访门诊”、参加查房情况、举办质控会议、院外宣教数及受益数、出院患者随访和具备独立办公室上差异具有统计学意义(P<0.05)。结论中国脑心健康管理师已经参与到脑卒中患者的全流程管理中,但是受到卒中中心等级和是否承担脑卒中筛查和干预项目的影响,各医院间资源配置和工作开展情况存在较大差异,下一步在全国范围内逐步推进脑心健康管理工作的开展,使脑心健康管理师在控制脑卒中发病风险,降低脑卒中发病率、复发率、致死及致残率方面发挥作用。
