OBJECTIVE: To investigate the relationship between OPRM1 118A/G gene polymorphism and oxycodone analgesic dose in patients with cancer pain. METHODS: DNA sequencing was used to detect the genotypies of OPRM1 118 A/G site in 203 patients with moderate and severe cancer pain, and to compare the relationship between the pain degree and the dose of oxycodone at 3 and 30 days after treatment in patients with different genotypes. RESULTS: The fequencies of AA, AG and GG genotypes at the OPRM1 118 A/G site were 34.78%, 52.70%, and 12.52%, respectively. The dosage of oxycodone in GG genotype was significantly higher than that in AA genotype and AG genotype (15.44±10.19 vs. 10.25±4.53, 10.49±5.26; 89.15±27.69 vs. 43.59±12.19, 48.27±18.79) on the 3 and 30 day after treatment, difference was statistically significant (P< 0.05). CONCLUSION For cancer pain patients with GG genotype of OPRM1 118A/G site, if they need to achieve the same analgesic effect as patients with AA and AG genotype, the dose of oxycodone should be increased.

Objective:To investigate the effectiveness of ramified flap of the lateral circumflex femoral artery for repairing complex wounds of lower extremity.Methods:A retrospective case series study was performed on 25 patients with complex wounds of lower extremity treated in Affiliated Hospital of Zunyi Medical University from September 2018 to September 2020. There were 18 males and 7 females at age of 18-69 years［（42.2 ± 3.7）years］. The wounds were located at the calf in 7 patients，at the ankle in 7 and at the dorsum of foot in 11. Single wide irregular wound was noted in 15 patients for an area of 10 cm × 9 cm to 18 cm × 12 cm，and 2 to 3 sites of wounds occurred in 10 patients with each wound ranging from 4 cm × 3 cm to 12 cm × 5 cm. All wounds were covered using ramified flap of the lateral circumflex femoral artery. All donor sites were closed directly. At the latest follow-up，appearance and texture of the flap，formation of scar on the donor sites and walking function of the affected limb were observed. One month after operation and at the latest follow-up，British Medical Research Association（BMRC）grade and Vancouver Scar Scale（VSS）score were used to evaluate the recovery of sensory function of the flap and scar formation of the donor sites，respectively.Results:All patients were followed up for 7-30 months［（12.1 ± 1.8）months］. At the latest follow-up，good appearance and soft texture of the flap were observed，leaving only linear scar at the donor sites and normal function of the affected limb. At the latest follow-up，there were 23 patients with BMRC at grade of S3 and S4 compared to none at 1 postoperative month（ P < 0.01），and the VSS score was 4-8 points［（6.0 ± 1.3）points］compared to 7-13 points［（9.9 ± 1.6）points］at postoperative 1 month（ P < 0.01）. Conclusion:For complex wounds of lower extremity，ramified flap of the lateral circumflex femoral artery has advantages of good recovery of the appearance，texture and sensory function of the recipient sites and only linear scar in the donor sites.

Objective:To analyze the therapeutic effect of modified cross-leg free skin flaps in repairing soft tissue defects of the lower leg.Methods:A retrospective case series study was conducted to analyze clinical data of 8 patients with soft tissue defects of the lower leg admitted to Affiliated Hospital of Zunyi Medical University from June 2018 to June 2020. There were 6 males and 2 females with the age range of 23-60 years［（39.6±5.7）years］. Area of defect was from 10.0 cm×4.5 cm to 21.0 cm×9.0 cm，with the size of flap from 12 cm×5 cm to 25 cm×10 cm. The free flaps were harvested to repair the wound of the affected leg and the blood vessels were anastomosed by cross-leg with the contralateral posterior tibial artery and vein at the first stage，including lateral circumflex femoral artery flap for 6 patients，superficial circumflex iliac artery flap for 1 and latissimus dorsi myocutaneous flap for 1. At the same time，the pedicled posterior tibial artery perforator flap or random flap was cut to wrap the vascular pedicle. After operation，both legs were placed in a parallel and straight position. After pedicle cleavage at the second stage，the posterior tibial artery and distal artery were re-anastomosed，and the flap was sutured to its original position. Incidences of pressure sores and deep venous thrombosis of the lower leg and patients' acceptance of the position were documented during leg crossing at the first stage. The survival of the flap was observed after pedicle amputation at the second stage. The appearance，texture，function of the affected limb and influence on the healthy leg were observed at the last follow-up. Simultaneously，the lower extremity functional score（LEFS）was used to evaluate the overall function of the affected leg and the Kofoed score to evaluate ankle function.Results:All patients were followed up for 6-18 months［（8.3±1.8）months］. There reported none of pressure ulcer or deep venous thrombosis of the lower leg，without resistance to body position at stage I. All flaps survived after pedicle amputation at stage II. The shape，texture and function of the injured leg were good，with no impact on function of the healthy leg at the last follow-up. The LEFS score of the affected leg and the Kofoed score of the ankle were increased from（31.5±6.9）points and（51.0±10.5）points preoperatively to（51.7±9.8）points and（84.8±8.1）points at the last follow-up（ P<0.01）. Conclusion:For patients with soft tissue defects of the lower leg，the treatment with modified cross free flap has advantages of relatively comfortable position，no impact on function of the healthy leg，good appearance and texture of the flap and satisfactory recovery of the affected leg.
