Methods: A population of 14 854 AMI patients with CAMI registration from 2013-01 to 2014-03 were studied, which included 10999 (74.0%) male and 3855 (26.0%) female. The gender related differences of clinical symptoms and triggering factors were analyzed in the population.
Results: The chest pain and severe sweating were the most common symptoms of AMI patient, there were 66.4%of patients with persistent chest pain and 63.7%of patients with severe sweating. Male patients were more with chest pain (67.8%vs 62.4%) and severe sweating (65.8%vs 58.0%) than female, while female patients were more with radiating pain (36.0%vs 31.0%) and nausea/vomiting (35.6%vs 25.0%) than male, all P<0.05. There were 19.4%of patients having clear cause of AMI, and physical stress was the most frequent trigger (48.5%) for AMI. Male patients usually had clear cause than female (20.9%vs 15.1%), especially because of physical stress (49.5%vs 44.5%) and excessive recent unhealthy lifestyles (15.4%vs 8.8%), all P<0.05.
Conclusion: Chest pain and severe sweating were the most common clinical symptoms for AMI patients in China, about 1/5 of them had triggering factors and it was more in male patients.

OBJECTIVE:
To evaluate the effect of the combined application of dissociate skin flap and vacuum sealing drainage (VSD) for the repairing for defect after surgical management of huge neck neoplasms.
METHOD:
Nineteen patients with huge neck malignant tumor involving the skin of the neck were given radical operation, making use of VSD covering the wound surface. After giving 6.65-7.98 mm Hg continuous negative pressure drainage for 72 h, the patients turned to be treated by intermittent negative pressure therapy with 2 min free interval after each treatment period for 5 min. After dismantling the VSD at 7th to 10th day postoperatively, the good wounds covered by granulation tissue were treated by the skin graft operation with dissociate skin flap from thighs; as for the wounds of which the granulation tissue didn't grow well and important cervical tissues was not fully covered by the granulation tissue, VSD was applied again for 1 week, followed by the skin graft operation.
RESULT:
Nineteen patients have received a total of 23 times of VSD wound treatment, one-stage operation time was significantly shortened. The granulation tissue grew faster on the wound after VSD treatment, and the important cervical tissues such as great vessels could be well covered. The infection and tumor recurrence were observed directly after dismantling the VSD. The skin graft transplantation would be performed after 1-3 weeks.
CONCLUSION
The treatment by vacuum sealing drainage combined with skin graft for surgical wounds of huge neck tumor postoperatively has the advantages of simple operation, little injury and promotion of the wound healing, which is an effective way for treatment of neck skin defect by surgical operation for the huge tumor.

OBJECTIVE:
To explore the analgesic mechanism of intrathecal trichostatin A (TSA) injection in a rat model of neuropathic pain induced by chronic constrictive injury (CCI).
METHODS:
Male SD rats were randomized into sham operation+ DMSO group (group S), CCI +DMSO group (group C), CCI +10 μg TSA group (group T), and in the latter two groups, rat models of neuropathic pain were established induced by CCI. The rats were given intrathecal injections of 10 μL 5% DMSO or 10 μg TSA (in 5% DMSO) once a day on days 7 to 9 after CCI or sham operation. The rats were euthanized after behavioral tests on day 10, and the lumbar segment of the spinal cord was sampled to determine the expression of histone deacetylase 4 (HDAC4) protein and mRNA and detect the differentially expressed miRNAs using a miRNA chip. MiR-190b-5p and miR-142-3p were selected for validation of the results using RT-qPCR.
RESULTS:
Compared with those in group S, the rats in group C showed significantly decreased paw withdrawal mechanical threshold (PWMT) from day 3 to day 10 after CCI ( < 0.05); intrathecal injection of TSA significantly reversed the reduction of PWMT following CCI ( < 0.05). Positive HDAC4 expression was detected mainly in the cytoplasm of the neurons in the gray matter of the spinal cord, and was obviously up-regulated after CCI ( < 0.05). Intrathecal injection of TSA significantly suppressed CCI-induced up-regulation of HDAC4 at 10 days after the operation ( < 0.05). Compared with the miRNA profile in group S, miRNA profiling identified 83 differentially expressed miRNAs in group C (fold change ≥2 or ≤0.5, < 0.05); TSA treatment reversed the expressions of 58 of the differentially expressed miRNAs following CCI, including 41 miRNAs that were decreased after CCI but up-regulated following TSA treatment. The results of real-time PCR validated the changes in the expressions of miR-190b-5p and miR-142-3p.
CONCLUSIONS
TSA suppresses CCI-induced up-regulation of HDAC4 and reverses differential expressions of miRNAs in the spinal cord of rats, which may contribute to the analgesic effect of TSA on neuropathic pain.
