Objective Modified Decoction for Driving Out Blood Stasis in the Blood Mannsion on ascites tumor model of transplanted H22 anti-tumor effect and the impact of VEGF. Methods Adult male mice 100, inoculated with H22 hepatoma cells, the establishment of ascites H22 transplanted tumor model, then divided into 10 groups were given saline, capecitabine, flavored Modified Decoction for Driving Out Blood Stasis in the Blood Mannsion (high, medium and low dose) was administered orally for 10 days, 11 days of treatment, observation of suppression tumor rate, the rate of change in life extension; detected by immunohistochemistry the expression of VEGF in tumors, SPSS13.0 software for statistical analysis. Results Capecitabine, flavored Xuefuzhuyutang (high, medium and low dose) inhibited tumor growth rates were 60%, 49%, 41%, 35%, life extension rate of the three groups were 1.68% 157.98%, 70.58%, 49.57% higher. Conclusion Modified Decoction for Driving Out Blood Stasis in the Blood Mannsion can inhibit tumor cell proliferation in tumor-bearing mice, significantly prolonged the survival time of mice, reduce the tumor tissue and tumor tissue expression of VEGF.

Objective:To introduce a novel clinical classification that can be applied to osteoradionecrosis treatment in an easy and considerably acceptable manner through a retrospective analysis of patients with osteoradionecrosis of the mandible (ORNM). Methods:The clinical data of 99 ORNM patients admitted to shanghai Ninth People's Hospital between 2000 and 2013 were summa-rized. A novel classification was established based on bone necrosis and soft tissue lesions. The new staging system was developed based onBandSclassifications. Corresponding strategies and methods of ORNM treatment at different stages were also proposed. Results:A new staging system with four different stages (i.e., stage 0:8 cases;stageⅠ:14 cases;stageⅡ:65 cases;and stageⅢ:12 cases) was proposed. Conservative treatment was applied to stage 0 patients, whereas sequestrectomy was performed in stageⅠcases. Marginal or segmental resection of the mandible was selected for stageⅡpatients;osteocutaneous flap or just soft tissue flap was also reconstructed. Conclusion:This new classification and staging system is easier to use and more acceptable for clinical evaluation than other systems.

Objective: To investigate the therapeutic effect of free superficial circumflex iliac artery perforator (SCIP)flap for reconstruction of soft tissue defects secondary to resection of retromolar and lateral buccal squamous cell carcinoma. Methods: From January 2014 to January 2017, eight patients with retromolar and lateral buccal squamous cell carcinoma received radical resection and reconstructed with SCIP flap immediately. CTA and color Doppler sonography were routinely performed before the surgery. According to the size of the defect in the recipient area, the flap vascularized by the perforator vessel was carefully prepared and transferred to the buccal-pharynx-palate composite defect. The recipient area and donor area were sutured tightly after arteriovenous anastomosis under microscope. The survival and functional recovery of the flap were observed after operation. Results: The flap sizes ranged from 5 cm× 6 cm to 7 cm×9 cm.The mean diameter of the superficial circumflex iliac arteries was 0.65 mm. And the mean diameter of the veins was 1.2 mm. The mean arterial pedicle length was 7.0 cm, and the venous pedicle length was 8.0 cm. Eight flaps were all survived. The shape of the buccal-parapharyngeal-palate was good and the mouth opening was normal after operation. Conclusions Superficial circumflex iliac artery perforator flap was a good choice for repairing the defect of parapharyngeal squamous cell carcinoma in the posterior molar region.
