Myocardin is a remarkably potent transcriptional coactivator which specifically expresses in cardiovascular system and directly binds to serum response factor.It activates transcription of a subset of SRF-regulated genes encoding cardiomyocytes and smooth muscle cells contractile proteins.Abnormal expression of myocardin is associated with cardiovascular diseases including atherosclerosis,myocardial hypertrophy and hypertension.Here,recent developments in the structure,expression and regulation of myocardin and its relation with cardiovascular diseases are reviewed.

Objective To compare the operative efficacy of low collar incision and L-shaped incision plus cervical plexus preser-ving lymphadenectomy in treating papillary thyroid carcinoma.Methods 9 3 inpatients with papillary thyroid carcinoma were ran-domly divided into the low collar incision group (n=37)and the L-shaped incision group(n=56)according to the random number table.The low collar incision group underwent the low collar type cervical plexus preserving lymphadenectomy,while the L-shaped incision group received the L-incision cervical plexus preserving lymphadenectomy.The postoperative 24-month follow up was per-formed.Then the clinical efficacy and the life quality of the patient were evaluated and compared between the two groups.Results (1)1 case of lymph node recurrence in the district Ⅱ after 20 months was found in the low collar incision group,1 case of lymph node recurrence in the district Ⅰ after 12 months and 1 case of lymph node recurrence in the districtⅣ after 22 months was found in the L-shaped incision group;no case of distant metastasis in the low collar incision group occurred during the follow up period, but 1 case of pulmonary metastasis in postoperative 5 months and 1 case of bone metastasis in postoperative 24 months occurred in the L-shpaed incision group.The differences in the occurrence rates of postoperative recurrence and metastasis had no statistical sig-nificance (2.70%vs.7.14%).(2)The scores of neck shoulder pain and numbness,incision appearance satisfaction degree in the low collar incision group were significantly higher than those of the L-shaped incision group (P<0.05).Conclusion Compared wtih L-shaped incision cervical lymphadenectomy,low collar incision cervical plexus preserving cervical lymphadenectomy has simi-lar high clinical efficacy,can significantly reduce neck shoulder pain and numbness,meet aesthetic requirements and especially is suitable for the patients with higher demands of the neck function preserving and the neck appearance.

Objective To investigate the effects of Huangkui Capsules on oxidative stress and micro-inflammation state in diabetic nephropathy patients with maintenance hemodialysis. Methods Forty-six patients with diabetic nephropathy who had received maintenance hemodialysis for over six month in Gansu Provincial People's Hospital were randomly divided into observation group (23 cases) and treatment group (23 cases) from January to December in 2014. Twenty healthy subjects who had physical examinations were selected as the control group at the same time. Observation group were given conventional hemodialysis for 4 hours, 3 times a week; treatment group were given conventional hemodialysis combined with Huangkui Capsules, orally, 2.5 g each time, 3 times a day. Both groups were treated for 8 weeks. Blood was collected before and after treatment for detection of hypersensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), white blood cell (WBC), malondialdehyde (MDA), cycle of advanced oxidation protein products (AOPP), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels. Results The levels of IL-6, TNF-α, AOPP, WBC, MDA and hs-CRP were significantly higher in the observation group and the treatment group compared with the control group before treatment (P<0.01), SOD and GSH-Px levels decreased (P<0.01); there was no statistical significance between the observation group and the treatment group (P>0.05). After treatment, the levels of IL-6, hs-CRP, MDA and AOPP increased in the observation group (P<0.05), GSH-Px and SOD decreased (P<0.05), there were no statistical significance in TNF-αand WBC (P>0.05);The levels of AOPP, TNF-α, hs-CRP, WBC, MDA and IL-6 in treatment group significantly decreased (P<0.01), GSH-Px and SOD significantly increased (P<0.01); there was statistical significance between the observation group and the treatment group (P<0.01). Conclusion Micro-inflammation state and oxidative stress exist generally in diabetic nephropathy maintenance hemodialysis patients. Huangkui Capsules can improve oxidative stress and micro-inflammation state in diabetic nephropathy maintenance hemodialysis patients.
