ABSTRACT

Objective:To explore the effects and mechanism of electroacupuncture (EA) on expression of myostatin (MSTN), muscle-specific ring finger protein 1 (MuRF1/Trim63), F-box only protein 32 (Atrogin-1/ Fbxo32), myogenic differentiation antigen (Myod) and myogenin (Myog) in traumatic spinal cord injury (TSCI) rats. Methods:A total of 45 adult female Sprague-Dawley rats were randomly divided into sham operation group (n = 12) and operation group (n = 33). The TSCI model was established with the modified Allen's method. After modeling, there were 24 survival rats and they were randomly divided into model group (n = 12) and EA group (n = 12). EA group was electroacupunctured at Dazhui (DU 14), Mingmen (DU 4) and bilateral Zusanli (ST 36) for 10 minutes, once a day, six times a week for 28 days. Basso-Beattie-Bresnahan (BBB) score was tested before modeling, and three days, seven days, 14 days, 21 days and 28 days after modeling. The rats were measured their body mass before and 28 days after modeling. The ratio of gastrocnemius wet mass was calculated; the cross-sectional area (CSA) and fiber diameter were measured by HE staining; the expression of MSTN, Trim63, Fbxo32, Myod and Myog mRNA were tested with real-time quantitative polymerase chain reaction (qPCR). Results:Three days, seven days, 14 days, 21 days, and 28 days after modeling, the score of BBB was lower in the model group than in the sham operation group (P < 0.01); seven days, 14 days, 21 days, and 28 days after modeling, the score of BBB was higher in EA group than in the model group (P < 0.01). Compared with the sham operation group, the mass of rats, the gastrocnemius wet mass, the CSA and the diameter of the muscle fiber were smaller in the model group (P < 0.05), while the expression of MSTN, Trim63, Fbxo32, Myod and Myog mRNA were higher (P < 0.05). Compared with the model group, the mass of rats, the gastrocnemius wet mass, the CSA, the expression of Myod and Myog mRNA were higher (P < 0.05) in EA group, while the expression of MSTN, Trim63 and Fbxo32 mRNA were lower (P < 0.05). Conclusion:EA might delay the gastrocnemius atrophy in TSCI rats by down-regulating the expression of MSTN, Trim63, Fbxo32 mRNA and up-regulating the expression of Myod and Myog mRNA via controlling the differentiation of the muscle satellite cells and the degradation of protein in skeletal muscle cells.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.</p><p><b>METHODS</b>Fifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups.</p><p><b>RESULTS</b>(1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05).</p><p><b>CONCLUSION</b>There is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.</p>
