Objective To study the effects of Fructus ligustri lucidi and its monomers, tyrosol and oleanotic acid, on the migration of mouse melanoblast cell line (NCCmelb4M5). Methods Cultured NCCmelb4M5 cells were treated with Fructus ligustri lucidi (0.0625, 0.125, 0.25, 0.5, 2 mg/mL), tyrosol (0.02, 0.04, 0.08, 0.16, 0.8 mg/mL) and oleanolic acid (0.0625, 0.125, 0.25, 0.5, 2.5 mg/mL), respectively,for 48 hours followed by the detection of cell proliferation with MTT assay. The working concentration of the three drugs was determined according to the results of MTT assay. Scratch and transwell assays were performed to observe the effect of Fructus ligustri lucidi and its monomers at working concentration on the migration of NCCmelb4M5 cells. Results Based on the results of MTT assay, the working concentration of Fructus ligustri lucidi, tyrosol and oleanolic acid was determined at 0.125 mg/mL, 0.08 mg/mL and 0.0625 mg/mL respectively, and at these concentrations, these drugs exhibited a cytotoxity lower than that of absolute alcohol with no obvious stimulation of cell proliferation. Scratch and transwell assay revealed a promoting effect of both Fructus ligustri lucidi and tyrosol on melanoblast migration (P<0.05), while oleanolic acid had little effect on melanoblast migration. Conclusions The extract of Fructus ligustri lucidi has a significant stimulatory effect on the migration of mouse melanoblasts, and tyrosol may be an active component of Fructus ligustri lucidi associated with confirmative effect on migration of mouse melanoblasts.

OBJECTIVE: To study the clinical and pathological features of pilomatricoma. METHOD: The authors retrospectively investigated the clinical and pathological materials of 399 patients with pilomatricoma. RESULT: Single lesion occurred in most patients (99%) and 56.39% of them were younger than 30 years. The male-female ratio was 1:1.33. The lesions which sizes average 1.22 cm were commonly emerged in the head, neck, and upper extremity. CONCLUSION Pilomatricoma is a slowly developed benign cutaneous tumour, but it can aggravate sometimes. It's manifestation is diversed and easily misdiagnosed. Early complete excision is recommended for hard or tenacious nodules on head, neck and upper extremity.

Objective To learn about the etiology , clinical characteristics and prognosis of infants with cholestasis jaundice. Methods The clinical data of 175 cholestatic patients were retrospectively analyzed , then the prognosis was followed-up with telephone. Results After analyzing the etiology , we found that among 175 patients , there were 42 with biliary atresia , of which 19 infants died , 4 recovered well after liver transplanta-tion , 8 had liver cirrhosis waiting for transplantation , 5 recovered well after Kasai Portoenterostomy and 6 lost contact. There were 2 patients with Bile duct dysplasia and 2 with congenital cholangiectasis and they had posi-tive outcomes. And 29 patients with Cytomegalovirus infection also had positive outcome. There were 16 patients with Heredity metabolic diseases , among which 13 patients were with Citrin protein deficiency; 10 had positive outcomes; 2 lost contact and 1 died. There were 3 patients with tyrosinemia , of which one had positive outcome;one lost contact and another got liver cirohosis waiting for liver transplantation. Four patients with TPN-related cholestasis all had positive outcomes. There were still 80 cases with unkown etiology , but 79 had positive out-comes and 1 case lost. The clinical characteristics showed that the infants with cholestatic jaundice often accom-panied by stool color changed , liver and spleen enlargement and so on , and often complicated with pneumonia , hypoalbuminemia and coagulation dysfunction and so on. Conclusion There are many etiologies for infants with cholestatic jaundice. Early diagnosis and early treatment would benefit the prognosis.

Objective To assess the clinical value of high-frequency electrocautery in the treatment of massive hemorrhage of presacral venous plexus. Methods The clinical data of 8 patients with presacral venous hemorrhage treated with high-frequency electrocautery from February 2005 to March 2008 were analyzed. Once the presacral venous hemorrhage happened, the bleeding site was pressed with a gauze or finger and the accumulated blood was aspirated. Then, while simultaneously withdrawing the gauze or finger over the bleeding sites, high-frequency electrocautery was applied with a power of 80-100 W to coagulate all the bleeding sites. Results High-frequency electrocautery was used to stop bleeding in the 8 patients, and no electrocautery related complica-tions occurred postoperatively. Conclusions High-frequency electrocautery for massive hemorrhage of presacral venous plexus is simple, efficient and safe.

Objective To measure stress distribution of the main bone architecture of the normal adult cadaveric foot and discuss the effect of plantar ligament injury on stress distribution. Methods Seven fresh adult cadaveric feet were used and 10 strain gauges attached to the bones of the longitudinal foot arch,including the calcaneus,navicular,medial cuneiform,1-5 metatarsal trunk,the distal part of the tibia and fibular,respectively.After the loading Was added to 700 N by almighty test machine,resistance strainmeter was used to measure surface strain of these bones.The results were processed statistically. Results The strain was varied based on different bone segments attached and increased with loading.Tensile force was always found at the medial part of the navicular,the distal part of the tibia and fibular,while the others showed compression all the time.Peak strain was found at calcaneus.followed by the second and third metatarsal.Strain on the surface of the bone segments changed greatly with different ligament injury(P＜0.05).Conclusion The bone surface stress of the longitudinal foot arch changes significantly when the plantar ligament is injured.
