Pleomorphic adenoma ranks first among parotid gland tumors. Surgical procedure, which includes enucleation, ex-tra-capsular resection, partial superficial parotidectomy (PSP), superficial parotidectomy (SP), and total parotidectomy (TP), remains to be the treatment of choice for pleomorphic adenoma. In the last century, physicians lacked understanding on the pathological character-istics of pleomorphic adenoma and facial neurotomia. Thus, simple enucleation of tumors has always been the major therapy for pa-tients to reduce the rate of facial nerve injury. However, postoperative recurrence was frequently observed in patients that have under-gone simple enucleation. In this study, the surgeons attempted to control the relapse rate by enlarging the scope of excision when remov-ing a pleomorphic adenoma, and by performing an extra-capsular resection procedure that was developed in the clinic. Although the tu-mor peplos was excised, the surgeons failed to control the relapse rate. SP and TP apparently decreased the relapse rate of the pleomor-phic adenomas. However, these therapies seem to be overcorrected by the aggravation of facial nerve injuries. PSP is a relatively ad-vanced technique that is currently used in parotid surgery. PSP reduces the rate of relapse and facial nerve injury, as verified by basic pa-thology research. Nevertheless, the controversy between advanced PSP and classic SP still exists. Plastic surgery, pathology research, and gene testing were used to evaluate the advantages of advanced PSP and classic SP. However, the research failed to derive a con-firmed result that can determine which treatment method is fit and unfit to treat pleomorphic adenoma. Our study reviews the trend of parotid surgery from a historic point of view.

Objective To investigate the effect of placing subcutaneous drain tube and preseting triclosan-coated polyglactin 910 suture with delayed suturing to incision infection after typeⅢabdominal surgery. Methords Dividing 504 patients with typeⅢincisions undergone abdominal surgery into 3 groups. The number of group A patients with thoroughly incision washing and primary triclosan-coated polyglactin 910 suture after abdominal surgery was 143. The number of group B with closed anterior rectus sheath, opened skin and subcutaneous fat with preseted triclosan-coated polyglactin 910 suture was 190. The number of group C with subcutaneous drain tube after abdominal surgery was 171. We compared the incidence rates of incision infection and the second phase debridement suture rates among the 3 groups. Results For the group A, B, C, the number of incision infection people was 11, 4, 3 and the incision infection rate was 7.69%, 2.11%and 1.75%respectively. The difference of the 3 groups incision infection rate were statistically significant (P<0.05). The incision infection rate of the group B and group C were lower than that of group A and the difference were statistically significant (P<0.016 7). There were no significant differences in second phase debridement suture rates among the 3 groups. Conclusion Preseting triclosan-coated polyglactin 910 suture with delayed incision sutue and placing subcutaneous drain tube can decrease the incision infection rates for type Ⅲpatients after abdominal surgery, but can not decrease the second phase debridement suture rates of the infectious incision.

injection). At the 5th, 10th and 15th months after operation, L2, L4 bone mineral density, L2, L4 maximum bending and compressive load, the ratio of anterior and posterior heights of L3 vertebrae to average height of L2 and L4 vertebrae, and the sagittal Cobb angle of L2 and L4 vertebrae were detected. RESULTS AND CONCLUSION:The bone mineral density, maximum bending and compressive load, vertebral height ratio at different time points after operation in experimental group were higher compared with the preoperative level (P < 0.05). The sagittal Cobb angle in experimental group was smaler compared with the preoperative level (P < 0.05). In the control group, the bone mineral density, maximum bending and compressive load at different time points after operation were al higher compared with preoperative level (P < 0.05). There were no significant difference of the vertebral height ratio and sagittal Cobb angle compared with the preoperative level. The bone mineral density, maximum bending and compressive load, vertebral height ratio at different time points after operation in experimental group were higher compared with the control group (P< 0.05). The sagittal Cobb angle was smaler compared with the control group (P < 0.05). These results demonstrate that percutaneous kyphoplasty bone cement injection can better improve the bone density, carrying capacity and kyphosis of osteoporosis fractures adjacent vertebrae.

To study the inhibitory effect of gigantol on proliferation, migration and invasion of human osteosarcoma U20S cells and to explore the mechanism. Methods: After being treated with different concentrations (10, 25, 50, 75, 100, 150 µmol/L) of gigantol for 24 and 48 h, the proliferation of U20S cells was detected by CCK-8 assay. Transwell assay was used to detect the effects of 25 µmol/L and 50 µmol/L gigantol on the migration and invasion abilities of U20S cells. The lipopolysaccharide (LPS) was used to induce inflammatory reaction in U20S cells before gigantol treatment; qPCR and WB were used to detect the mRNA and protein expressions of NF-κB (p65), TNF-α, IL-6 and PRL-3, respectively. Results: Different concentrations of gigantol could all inhibit the proliferation of sarcoma U20S cells at different time (P<0.05 or P<0.01). The 25 µmol/L and 50 µmol/L of gigantol could significantly inhibit the migration and invasion of osteosarcoma U20S cells (all P<0.01); at the same time, it could inhibit the protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 (P<0.05 or P<0.01). After LPS induction, the mRNA and protein expressions of NF-κB, TNF-α, IL-6 and PRL-3 in U20S cells were significantly increased (all P<0.01); however, the consequent treatment with gigantol (25 and 50 µmol/L) reversed the effects of LPS on U20S cells obviously (P<0.05 or P<0.01). Conclusion: Gigantol can inhibit the proliferation, migration and invasion of osteosarcoma U20S cells, and its mechanism may be related to the regulation of NF-κB/PRL-3 signaling pathway.

Objective To explore the clinical characters, diagnosis and treatment methods of placenta accreta. Methods A retrospective analysis was made of 47 cases of placenta accreta admitted during May 1997 to May 2007 into Peking Union Medical College Hospital. They included 17 cases in the second trimester and 30 cases in the third. Results Among all the patients, the incidence of placenta accreta was 0. 262% ( 47/17 918 ). Most of these cases ( 81%, 38/47 ) experienced a uterine procedure.30% (14/47) of the cases were found with placenta previa and 11% ( 5/47 ) with myoma in the current pregnancy. 11% (5/47) of all the cases suffered postpartum hemorrhage. In the 17 cases in the second trimester, 12 were diagnosed by uhrasonography and 5 by clinical evidence . While in the 30 cases in the third trimester, 8 were diagnosed by biopsy, 2 by uhrasonography, and 20 by clinical evidence. 45 cases were cured by conservative treatment, which included dilatation and curettage, uterine artery embolization (UAE) with or without methotrexate (MTX), tamping B-lynch suture, singly with MTX, and mifepristone. Only 2 cases received cesarean hysterectomy. Conclusions The incidence of placenta accreta seems on the rise. The incidence in the second trimester is higher than that in the third. In the second trimester, most cases can be diagnosed by uhrasonography after labor, and presently UAE is the best conservative management. While in the third trimester clinical evidence is the most frequent diagnostic approach. A majority of the cases could be cured by conservative therapies, which help them avoid a hysterectomy.

Objective:Facial nerves can be dissected using anterograde and retrograde approaches. The optimal technique for the facial nerve dissection of a patient with benign parotid tumor has not yet been determined. This study focused on facial nerve dysfunc-tion and recovery rate after anterograde and retrograde facial-nerve dissections. Methods:The data of 110 patients with benign carotid adenoma from the Head and Neck Department of this hospital who were hospitalized between January 2011 and January 2013 were col-lected. These patients were divided into groups A (n=52) and B (n=58). Anterograde and retrograde dissections of the facial nerve were performed on group A and group B patients, respectively. Based on the preferential order of dissection, group B was divided into groups B1, B2, and B3 representing the zygomatic, buccal, and marginal mandibular branches, respectively. The patients were postoperatively observed to check for potential symptoms, such as facial paralysis along with its severity and recovery. The House-Brackmann grading system was used to assess all patients. Results:The operation could be successful, with better nerve exposure, using these approaches. Statistical differences were observed in the nerve injury and recovery rates between the groups, with group A better than group B, and group B2 better than the other two groups (P<0.05). Conclusion:Anterograde facial nerve dissection should be routinely used in be-nign parotid tumor, and the buccal branch of facial nerve dissection should be preferentially considered when no other option apart from retrograde dissection is available.
