Objective To investigate the effect of suspended moxa stick moxibustion on points Shenshu(BL23) and Guanyuan(CV4) on the pituitary-adrenal axis and the pituitary-thyroid axis in rats with kidney yang deficiency. Method A rat model of corticosterone kidney yang deficiency was made by intramuscular injection of hydrocortisone. The rats were randomized into model control and moxibustion treatment groups. A blank control group was set up. The moxibustion treatment group received suspended moxa stick moxibustion on points Shenshu and Guanyuan 20 min once daily, for a total of 14 times. After the completion of treatment, serum CORT, ACTH, T3, T4 and TSH contents were measured by ELISA and pituitary expressions of ACTH and TSH mRNA were determined by RT-PCR. Result There was no significant difference in serum CORT (P>0.05), there were significant differences in serum ACTH, T4 and TSH and pituitary ACTH and TSH mRNA (P<0.05) and there was a very significant difference in serum T3 (P<0.01) between the moxibustion treatment and model control groups. There were no significant differences in the above indicators between the moxibustion treatment and blank control groups (P>0.05). Conclusion Suspended moxa stick moxibustion on points Shenshu and Guanyuan produces a therapeutic effect on rat kidney yang deficiency by decreasing serum TSH content, down-regulating pituitary TSH mRNA expression, increasing serum ACTH, T3 and T4 contents and up-regulating pituitary ACTH mRNA expression.

Objective To investigate the effect of Santong electroacupuncture (EA) on mRNA and protein expression of p75 neurotroph-in receptor (p75NTR) in rats with spinal cord injury (SCI). Methods A total of 72 female Sprague-Dawley rats were randomly assigned to sham operation group (group A, n=8) and model group (n=64). In the model group, Allen's method was used to make SCI rats model, in which 48 survived model rats were further subdivided into model control group (group B, n=12), EA group (group C, n=12), inhibitor Nogo extra cellular peptide residues 1-40 (NEP1-40) group (group D, n=12) and EA+inhibitor NEP1-40 group (group E, n=12) according to de-sign proposal. The treatment groups were electroacupunctured on Dazhui (GV14) and Yaoyangguan (GV3), bilateral Ciliao (BL32) and Zu-sanli (ST36) with loose-tight wave, for 20 minutes every day. After 7 and 14 days of treatment, injured spinal cord tissue was extracted for detecting. The mRNA and protein expression of p75NTR was detected by real-time fluorescent quantitative PCR, in situ hybridization and Western blotting respectively. The hind limb motor function was assessed with Basso-Beattie-Bresnahan (BBB) score. Results The BBB score increased in the treatment groups compared with group B, and was higher in group E than in groups C and D (P<0.05), as well as on the 14th day than on the 7th day in all the treatment groups (t>2.623, P<0.05). The mRNA and protein expression of p75NTR in spinal cord tissues decreased in the treatment groups compared with group B (P<0.05), and no significant difference was found among the treatment groups (P>0.05). Conclusion Santong elerctroacupuncture treatment could improve the hind limb motor function, which may associate with inhibition of the mRNA and protein expression of p75NTR in rats after SCI.

AIM: To investigate the effects of protein C activator (PCA) from Agkistrondon acutus venom ( AAV) on the tension of thoracic aorta rings isolated from the rats with sepsis.METHODS:The model of sepsis was es-tablished by intraperitoneal injection of lipopolysaccharide ( LPS) .SD rats were randomly divided to 6 groups ( n=6 ):sham group, LPS group, PCA intervention group (LPS+PCA, PCA at doses of 0.1 mg/kg, 0.3 mg/kg and 0.6 mg/kg) and LPS+polymyxin B (at dose of 0.2 mg/kg) group.Using perfusion experiment in vitro, the tension of the aortic rings was measured by biological signal analytical system.RESULTS:The values of MABP, HR, LVDP and ±dp/dtmax were significantly lower in LPS group than those in sham group and LPS+PCA groups.Compared with sham group, the relaxa-tion response to acetylcholine ( ACh) and the contractile response of aorta rings induced by phenylephrine ( Phe) were sig-nificantly decreased in LPS group, which were increased significantly in PCA intervention group ( especially at dose of 0.6 mg/kg) compared with LPS group.The dose-response curve of aorta contraction with denuded endothelium induced by Phe shifted down significantly in LPS group compared with sham group, and no significant difference between LPS group and PCA intervention group was observed.Also no statistical difference was found in non-endothelium dependent relaxation of aortic rings induced by sodium nitroprusside among the groups.Pretreatment of N-nitro-L-arginine methl ester and methyl-ene blue increased the contraction amplitude of aortic rings induced by Phe.CONCLUSION:PCA from AAV effectively reverses the hypoergia of the vessels in rats with sepsis through protecting vascular endothelium, the mechanism of which may be mediated by inhibiting NO-GC-cGMP signal transduction pathway.

Objective To provide anatomical information and clinical application of periosteal perforator bone-skin flap of proximal lateral tibia. Methods From March, 2015 to March, 2017, 15 fresh cadavers who underwent injected with imaging technology and dissected with layer by layer. The origins, branches, distribution and anastomosis of periosteal perforator vessels in the proximal lateral tibial were observed. Sixteen patients of composite tissue defect in hands and feet were repaired with the method of free transplantation of this flap from March, 2015 to March, 2017. Injured area was from 3.0 cm × 0.8 cm to 6.0 cm × 5.5 cm. Bony defect size was from 1.7 cm × 1.5 cm × 1.0 cm to 5.0 cm × 1.0 cm × 1.0 cm. The bone-skin flap size ranged respectively from 3.0 cm × 0.8 cm to 6.0 cm × 5.5 cm and 1.6 cm ×1.0 cm × 0.8 cm to 5.0 cm×1.0 cm × 1.0 cm. Postoperative followed-up was done termly. Results The diameter and superficial length of the main perforators respectively were 0.5 to 1.2 mm and from 2.5 to 4.3 cm. The followed-up time was from 6 to 24 months in 14 cases, with the results of the bone-skin flaps presented favourable contours and good functions. The healing time of bone flap was 2 to 4 months. The function of shank was normal. Conclusion The periosteal perforator of proximal lateral tibia has favourable appearance, constant vascular pedi-cle, reliable blood supply and large diameter. The free transplantation of this flap offers a satisfactory alternative for repairing the small and medium-sized area of composite tissue defects of hands and feet.

OBJECTIVE: To establish a micellar electrokinetic capillary chromatography-based method for identification and quantitative detection of interleukin-12 (IL-12) and analysis of its unfolding process. METHODS: An uncoated fused-silica capillary (inner diameter 50 μm) with a total length of 48.5 cm (40 cm to the detector) was used for the experiment. The factors influencing the separation efficiency of IL-12 were analyzed, and a standard curve of IL-12 concentration was established. The mixture of IL-12 and anti-IL-12 antibody was incubated in a water bath at 38 ℃ for 40 min, and capillary electrophoresis was then performed under the same conditions. The results were compared with those of IL-12 and anti-IL-12 antibody to identify IL-12. IL-12 and dithiothreitol (DTT) were incubated at 60 ℃ in water bath for different lengths of times, and the unfolding process of IL-12 was analyzed based on electrophoresis results of IL-12 in different states. RESULTS: A micellar capillary electrophoresis on-line sweep method was established with 80 mmol/L borate (pH=9.3) containing 30 mmol/L sodium dodecyl sulfate (SDS) as the buffer solution. This system showed a good linear relationship between the peak area and the mass concentration of IL-12 with a linear correlation coefficient of 0.9991 within the linear range of 2 to 120 ng/L. As the incubation time of IL-12 and DTT prolonged, the disulfide bond of IL-12 gradually opened and resulted in distinct changes in the protein peak. CONCLUSIONS This capillary electrophoresis-based method is simple and sensitive for IL-2 analysis and allows rapid detection of changes in IL-12 content in the setting of tumors and analysis of the possible causes.

Objective: To explore the anatomy and clinical application of stepladder V-Y advanced flaps based on the lateral calcaneal artery perforator. Methods: Twenty-four lower extremities from 12 adult cadavers were dissected to investigate the perforators emerging along the lateral edge of the achilles tendon, in terms of amount and distribution, relative to the tip of the lateral malleolus. Based on the anatomical findings, stepladder V-Y advanced flaps, based on the perforator(s) of the lateral calcaneal artery (LCA) or the peroneal artery (PA), were used for reconstruction of lower-posterior heel defects in 22 cases. Results: Twenty-four lower extremities from 12 adult cadavers were successfully dissected. The peroneal artery continued to be the lateral calcaneal artery at the level of (6.0±1.4) cm above the tip of the lateral malleolus. Both of them have the perforators distributed to the skin in the achilles tendon area. In the space from the tip of the lateral malleolus to 8.0 cm and above, a total of 71 perforators with diameter larger than 0.5 mm were found in all extremities. Among them, 9%(7/71) were originated from peroneal artery, and 91%(64/71) were the lateral calcaneal artery. In the 22 cases of clinical application, the pedicle of flaps were used, based on the perforator of lateral calcaneal artery and (or) peroneal artery. The size of flaps ranged from 3.5 cm×9.0 cm to 5.0 cm×10.0 cm.There were 3 cases of skin necrosis at the tip of the flap, which were healed after dressing change. The other flaps had completely survived, and the wound healed in the first stage. Follow-up last for 8-24 months after operation. All patients had well recovery of ankle flexion, extension and appearance. They were able to weight-bearing walk, with natural gait. The texture and sensation of the flaps were similar to that of the surrounding skin. There were few obvious scar or contracture deformity. The functional recovery was satisfied. Conclusions The blood supply in the achilles tendon region is mainly from the lateral calcaneal artery, and partly from the peroneal artery. Stepladder V-Y advanced flap based on the lateral calcaneal artery perforator can be used with reliable blood supply and sensation reconstruction, which is a good choice to repair small to medial wounds in heel area.
