ABSTRACT
Zhuye Shigaotang， first recorded in ZHANG Zhongjing's Synopsis of the Golden Chamber （《金匮要略》）， is a commonly used prescription for treating heat syndrome in modern times. However， physicians of the past dynasties have different opinions on the mechanism of Zhuye Shigaotang in disease treatment. Based on HUANG Yuanyu's theory of Qi circulation， this paper holds that the root cause of the diseases treated by Zhuye Shigaotang is the deficiency of spleen and stomach in the middle energizer and the dysfunction of ascending and descending. The failure of Yin ascending leads to the failure of Yang transformation， and the failure of Yang descending causes the failure of Yin generation. As a result， heat and fire become predominant in the heart， lung， and stomach， which causes Qi counterflow and fluid consumption. Based on this pathogenesis， Zhuye Shigaotang is mainly composed of pungent， warm， sweet， and cold herbs. The combination of these herbs can protect the spleen and stomach and recover the Qi movement in the middle energizer， thereby clearing heat and fire， descending Qi， and promoting the generation of Qi and fluid. In clinical practice， this prescription can be applied to treating the syndromes of deficiency in spleen and stomach， dysfunction of middle energizer in transportation， dysfunction of ascending and descending， excessive heat and fire， and Qi counterflow and fluid consumption. The interpretation of Zhuye Shigaotang from the theory of Qi circulation can provide a new idea for differentiating syndromes， seeking causes， and developing prescriptions， which broadens the scope of clinical application of this prescription and provides a reference for interpreting ZHANG Zhongjing's method of compatibility.
ABSTRACT
Objective:To investigate the effect and indications of pedicled myocutaneous flap and modified Masquelet technique in the repair of diabetic soft tissue and tibial bone defects.Methods:From January, 2017 to October, 2019, data of surgical treatment of 20 patients with diabetic soft tissue and tibial bone defects were retrospectively studied. The detects were repaired by the pedicled myocutaneous flap combined with modified Masquelet technique. There were 13 males and 7 females aged 40 to 65(average 51) years old. Preoperative ultrasound and CTA had confirmed that there was no occlusion in anterior and posterior tibial arteries. After debridement, the bone defect was 4-9 cm in length and the soft tissue defect was 3 cm×6 cm to 7 cm×10 cm. The initial antibiotic loaded bone cement filling of the bone and soft tissue defects was carried out. Then at 7-10 days later, had the bone cement placed earlier removed the remaining spaces of bone defect were again filled by antibiotic loaded bone cement. Meanwhile, the pedicled myocutaneous flap was transferred to repair the wound. The second stage of Masquelet technique was performed later, with an interval of 8-12(mean 9) weeks. The healing of wound and bone defect, and the complications were recorded. At 12 months after the surgery, the healing and appearance of the flap were evaluated by the standard proposed by Zhang Hao, and the functional recovery of the adjacent joint was evaluated by Johner-Wruhs standard. The treatment was considered successful when the symptoms were disappeared and no recurrence occurred.Results:All patients entered 13 to 28 months of follow-up, 20 months in average. The healing time for bone defect was 6-11 (average 9.0) months. All myocutaneous flaps survived with 18 flaps healed in the stage one and 2 delayed healing. Nine flaps appeared almost normal and 11 shown bloating. Seventeen flaps were found with partial sensation and 3 without sensation at all. The temperature of 7 flaps was found normal and 13 were slightly lower. Fourteen donor site scars were mild and 6 were obvious. The overall curative effect was satisfactory. Two patients had recurred infection. The rates of excellent and good functional recovery, infection control and success of treatment were at 90%(18/20) for each.Conclusion:Pedicled myocutaneous flap combined with modified Masquelet technique can repair diabetic soft tissue and tibial bone defects. It has a good therapeutic effect for short and medium terms.
