Objective:To investigate the clinical effect of combining medial plantar flap with medial foot flap for repairing weight-bearing area defects of the foot.Methods:A retrospective case series study was used to analyze the clinical data of 12 patients with weight-bearing area defects of the foot, who were admitted to the Affiliated Hospital of Zunyi Medical University from March 2020 to March 2022. There were 9 males and 3 females, with the age of 27-62 years [(39.3±8.7)years]. There were 4 patients with palm defects and 8 with heel defects. The defect area ranged from 10 cm×8 cm to 13 cm×12 cm. The cutting area of skin flap ranged from 11 cm×8 cm to 14 cm×13 cm. A total of 5 patients were treated with free flaps (4 patients with palm and 1 with heel defects) and 7 with pedicled flaps (all with heel defects). The flap donor areas were repaired with skin grafting. The flap survival was observed after surgery. At the last follow-up, the appearance, texture, and two point discrimination of the flap were recorded; the foot function was evaluated by Maryland foot function score; the sensory function of the reconstructed skin flap was evaluated by testing the two-point discrimination using a bipedal gauge.Results:The patients were followed up for 6-24 months [(11.8±5.3)months], and all the flaps survived. At the last follow-up, the flaps were free of any swelling and ulceration, with good texture and no sliding. The Maryland foot function score was (92.8±7.2)points at the last follow-up, which was significantly higher than the preoperative (36.6±6.1)points ( P<0.01), being excellent in 9 patients and good in 3. The two-point discrimination of the reconstructed flap was (17.8±5.7)mm at the last follow-up, and there was no significant difference compared with the contralateral (16.3±5.1)mm ( P>0.05). The sensation of the flap returned to normal. There were residual scars in the flap donor area after skin grafting, but no significant impact on foot movement. Conclusion:The medial plantar flap combined with medial foot flap has a large cutting area and good texture, meets the functional requirements, and achieves good postoperative sense recovery, making it a good choice for the repair of weight-bearing area defects of the foot.

Objective With Dongcheng District residents for research, we used questionnaires, personal interviews, expert evaluation, systems analysis to study the health education mode of traditional Chinese medicine, and provide overall planning, pilot, summary of adjusted step by step implementation of final evaluation. In the adoption of a three-year health research and practice of traditional Chinese medicine, we have achieved good results. Area of traditional Chinese medicine culture has been strengthened, traditional Chinese medicine theory and appropriate technology have been widely used in the resident wellness activities. An appropriate health education mode of health education of traditional Chinese medicine is significant to highlight features of traditional Chinese medicine.

OBJECTIVETo evaluate the effects of pre-operative intra-arterial infusion chemotherapy on colorectal cancer.

METHODSTwenty-eight patients with colorectal cancer, treated by surgery from February to October 2000, were divided into two groups randomly. There were 12 patients in group A (pre-operative intra-arterial infusion chemotherapy) and 16 in group B (control). Arterial contrast technique was used in group A, then mitromycin 10 mg, 5-Fu 1,000 mg, epirubicin 60 mg were given through Weidner's way.

RESULTSMicro-vessel density in the center, surface of the tumor and adjacent tissue around the tumor were 40.46 +/- 7.06, 52.27 +/- 18.40, 49.92 +/- 8.15 in group A, and 46.09 +/- 12.21, 73.44 +/- 22.06, 51.94 +/- 12.64 in group B. Micro-vessel density on the surface in group A was significantly lower than that of group B (P < 0.05), with no significance between the center and the adjacent tissue.

CONCLUSIONPre-operative intra-arterial infusion chemotherapy is able to reduce micro-vessel density on the surface of colorectal tumor.
