OBJECTIVETo explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.

METHODSFifty-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.

RESULTS(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).

CONCLUSIONThere 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.

Aim To study the protective effects of sphingosine 1-phosphate (S1P) postconditioning on rat myocardial cells injured by hypoxia/reoxygenation in reperfusion injury salvage kinase ( RISK ) signal path-way. Methods The cultured rat H9c2 cells were ran-domly divided into seven groups: ( 1 ) control group;(2) hypoxia/reoxygenation (H/R) group; (3) S1P group;(4) S1P+LY294002 group(S1P+LY); (5) LY group; ( 6 ) S1 P +PD98059 group ( S1 P +PD );(7) PD group. The viability of H9c2 cells was detec-ted using MTT method. The content of MDA in the cultured medium and the activity of T-SOD and Mn-SOD were measured with colorimetry. The concentra-tion of intracellular free calcium ion was detected by confocal microscopy. The rate of cell apoptosis was de-termined by flow cytometric analysis. Western blot was used to assess phosphorylation of Akt and ERK1/2 in H9c2 cells. Results Compared with the H/R group, S1P significantly increased vaibility of cells, lowered the rate of apoptosis, decreased the content of MDA in the culture medium, increased the activity of T-SOD and Mn-SOD, reduced concentration of intracellular calcium and increased the phosphorylation of Akt and ERK1/2 . When added LY294002 or PD98059 , the effects of S1P above were inhibited. Conclusion S1P protects H9 c2 cells against hypoxia/reoxygenation inju-ry. The protection of S1P was inhibited by LY294002, the inhibitor of PI3 K/Akt and PD98059 , the inhibitor of ERK1/2 . S1 P protects H9 c2 cells against hypoxia/reoxygenation injury via RISK pathway.
