Objective To observe the clinical efficacy of flexor-extensor alternate electroacupuncture with low-frequency stimulation in improving the wrist-hand function after high spinal cord injury.Method Forty patients with high spinal cord injury were randomized into a treatment group and a control group, 20 cases in each group. The treatment group was intervened by flexor-extensor alternate electroacupuncture with low-frequency stimulation, while the control group was by electroacupuncture. The Lindmark score, MAX and IEMG of sEMG were observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The MAX, IEMG of sEMG and Lindmark scores were significantly changed after the treatment in both groups (P<0.05). The sEMG signal values and Lindmark score of the treatment group were significantly different from that of the control group after the treatment (P<0.05). The total effective rate was 95.0% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Flexor-extensor alternate electroacupuncture with low-frequency stimulation is an effective method in improving the wrist-hand function after high spinal cord injury.

Objective:To observe the clinical effects of half puncture plus transcutaneous acupoint electric stimulation in the treatment of infantile facial paralysis. Methods:A total of 60 patients with infantile facial paralysis were divided into a treatment group and a control group by the random digital table, 30 cases in each group. The treatment group was treated with half puncture plus transcutaneous acupoint electric stimulation. The control group was treated with routine acupuncture. Before and after treatment, House-Brackmann (H-B) grading was used to evaluate the sick children respectively. The total effective rates were compared between the two groups after treatment. Results:After 6-course treatments, the total effective rate was 96.5% in the treatment group and 80.0% in the control group, there was a statistical difference between the two groups (P<0.05) in comparison of the total effective rate. After 6-course treatments, H-B scores were all elevated than those before treatment in the two groups (P<0.05); there was a statistical difference between the two groups (P<0.05). Conclusion:Half puncture plus transcutaneous acupoint electric stimulation is better than routine acupuncture in curative effect for infantile facial paralysis.

Objective To build the steady framework of the nasal tip by using caudal septal advancement technique to obtain the permanent nasorostral configuration.Methods From Oct 2009 to Apr 2011,the caudal septal advancement technique was used to reconstruct the septum to make the septal anterior angel and the caudal septal margin reach the anticipated height and length of the tip,then medial crus and the vault of the lower lateral cartilage were sutured to the caudal septum to form the steady supporting structure of the nasal tip.Results 3-16 months follow-up in 26 cases showed that 2 cases appeared the staircase deformity in the junction of the bone and the cartilage in the dorsum,but the nasorostral configuration was good.3 cases whose tip and columella were deviated before the operation appeared the deviation again after 3 months but the nasorostral configuration was better than before.The other 21 cases were good.Conclusions It is a available method of using caudal septal advancement technique to form the steady nasorostral configuration.

Nuclear factor kappa B (NF-κB) is an important nuclear transcription factor involved in a wide range of inflammatory mediators,adhesion molecules,chemokines and inflammatory-related enzymes in gene regulation,causing immune damage.Vascular cell adhesion molecule-1 (VCAM-1),an adhesion molecule,belongs to the immunoglobulin superfamily and can mediate adhesion of inflammatory cells and endothelial cells caused by inflammatory injury.VCAM-1 gene promoter region contains a series of many of the features of NF-κB site.NF-κB activation can increase the expression of VCAM-1 that causes the immune and inflammatory injury.Present study has found that immune inflammation is the basis of a variety of renal diseases.NF-κB,VCAM-1 in kidney disease and its research progress may be discussed in this article.
