OBJECTIVETo investigate the reconstruction of 1/4 defect on upper-lip vermilion with a lower-lip vermilion compound tissue flap pedicled at oral commissure.
METHORDSAt the first stage, the lower lip mucosal flap pedicled by inferior labial artery was transposed to reconstruct the defect on upper lip vermilion and tubercle. The defect at the donor site was closed directly. At the second stage, the flap pedicle was cut off and revised.
RESULTS6 patients were treated with satisfactory aesthetic results. All the flaps survived completely. The oral commissure kept normal with no obvious scar at the donor sites.
CONCLUSIONSThe modified crosslip vermilion flap pedicled at oral commissure has the advantages of avoiding inconvenience in feeding, speaking and cleaning. The procedure is simple with available blood supply. Both aesthetic and functional results are satisfactory.

BACKGROUND: Previous studies have verified that under normal culture of neural stem cells (NSCs), folic acid can accelerate proliferation of NSCs by phosphorylation of mitogen activated protein kinase path activation ERK1/2. OBJECTIVE: To investigate the effect of folic acid on NSC extracellular signal regulatory protein kinase pERK1/2 under hypoxic condition. METHODS: NSCs from Neonatal rats were cultured in vitro by serum-free culture method, and incubated in a flask at 1×10~8/L. Except normal control group, self-made hypoxia equipment was used in the hypoxia model, folic acid deficiency and folic acid supplemented groups at day 3. At 37 ℃, hypoxia culture was conducted in the thermostat for 6 hours. The contents of folic acid were 4 mg/L, 4 mg/L, 0.65 mg/L, 8 mg/L in the four groups. Cells following 6 days were collected to count the density using trypan blue. RT-PCR was utilized to detect pERK1/2 mRNA expression. Western blot assay was employed to determine pERK1/2 protein expression. RESULTS AND CONCLUSION: Compared with the normal control group, the proliferation of NSCs and the expression of ERK1/2mRNA and pERK1/2 protein were decreased significantly in the hypoxia model group. Compared with the hypoxia model group, the proliferation of NSCs and the expression of ERK1/2mRNA and pERK1/2 protein were increased in the folic acid supplemented group, whereas decreased in the folic acid deficiency group. There were significant differences among groups (P < 0.001). Above-described results verified that folic acid supplementation can activate ERK1/2 phosphorylatin and accelerate proliferation of NSCs under hypoxia condition.

OBJECTIVE: To evaluate the feasibility and image quality (IQ) of prospectively high-pitch coronary CT angiography (CCTA) with low contrast medium injection rate at 70 kVp. MATERIALS AND METHODS: One hundred and four patients with suspected coronary artery disease (body mass index < 26 kg/m², sinus rhythm and heart rate < 70 beats/min) were prospectively enrolled and randomly divided into two groups. In group A and group B, 28 mL and 40 mL of 370 mgI/mL iodinated contrast media was administrated at a flow rate of 3.5 and 5 mL/s, respectively. CT values, noise, signal-to-noise ratio, contrast-to-noise ratio (CNR) of the proximal segments of coronary arteries and subjective IQ were evaluated. RESULTS: The CT values and noise in group A were significantly lower than those in group B (434–485 Hounsfield units [HU] vs. 772–851 HU, all p < 0.001; 17.8–22.3 vs. 23.3–26.4, all p < 0.005). The CNRs of the right coronary artery and left main artery showed no statistical difference between the two groups (42.1 ± 13.8 vs. 36.8 ± 16.0, p = 0.074; 38.7 ± 10.6 vs. 38.1 ± 17.0, p = 0.819). No statistical difference was observed between the two groups in IQ scores (3.04 ± 0.75 vs. 3.0 ± 0.79, p = 0.526) and diagnostic ratio (96.1% [50/52] vs. 94.2% [49/52], p = 0.647). CONCLUSION: Prospective high-pitch CCTA at 70 kVp with 28 mL of contrast media and injection rate of 3.5 mL/s could provide diagnostic IQ for normal-weight patients with heart rate of < 70 beats/min.
