       [0087]    Make the pharmaceutical composition in the present invention according to the method The pharmaceutical composition was prepared according to the method of example 1 except that the composition was consist of 12 Kg of beeswax and 88 Kg of sesame oil extract containing 0.5 kg of  Radix Scutellariae, Coptis Chinensis, Cortex Phellodendri, Pericarpium Papaveris  and  Lumbricus  respectively, and the temperature of sesame oil was kept at 155° C. and stirred for 40 min to afford pharmaceutical composition  8 . 
       Experimental Example 1 
       [0088]    Referring to  FIG. 1 , Deep degree III burns combined with bone burn injury were firstly treated with pharmaceutical composition  7  and  8 . In pharmaceutical composition  7  and  8 , the individual weight proportion of  Radix Scutellariae, Coptis Chinensis, Cortex Phellodendri, Pericarpium Papaveris , and  Lumbricus  is 0.5% and 7% respectively of the total weight of the sesame oil extract. The necrotic tissues of deep burns were liquefied and removed and the new granulation tissues grew out, while the burnt bone tissues still did not have vitality. Using the pharmaceutical composition  1  on the wounds directly and the necrotic tissues on the bone membrane and bone were removed after 2 days ( FIG. 2 ). 
         [0089]    Then drill the holes on the bone with 0.5 cm interval space and deep to the bone marrow until the seepage of bone marrow blood and then the pharmaceutical composition  1  was used directly to cover the drilled bones and holes with the thickness of about 1-3 mm. The dressing was changed twice in every morning and night respectively ( FIG. 3 ). 
         [0090]    After several days, the new skin regenerated from the original bone granulation tissues and the new granulation tissue grew out from the drilled holes ( FIG. 4  and  FIG. 5 ). After continuous application, the skin on the granulation tissues expanded and healed the wounds and the new granulation tissues grew out of the holes connected with each other and regenerated new skin on the new bone granulation tissues ( FIG. 6 ). 
       Experimental Example 2 
       [0091]    Referring to  FIG. 2 , the patient was subjected to the electrical injury on the top of head combined with skull periosteum burnt and skull surface necrosis. Firstly, the pharmaceutical composition  7  and  8  were used as the control drugs for 25 days. After treatment, there was no obvious improvement of skull necrotic surface. Then the pharmaceutical composition  2  obtained from example 2 was used to continue the treatment. The treatment method was to apply the pharmaceutical composition on the wounds directly with thickness of about 1-3 mm and the dressing was changed twice in every morning and night respectively for 7 days. 
         [0092]    After 7 days treatment, remove the necrotic bone tissues from outside to inside with surgical debridement and then drill the holes on the bones with drilling interval less than 1 cm until the bleeding of bone marrow. Then the pharmaceutical composition  2  was applied on the wounds with the thickness of about 1-3 mm and the dressing was changed twice in every morning and night respectively ( FIG. 8 ). 
         [0093]    After 10 days, the granulation tissues grew out of the drilled holes and new skin gradually regenerated and connected with each other to close the bone wounds ( FIG. 9 ). 
         [0094]    After the bone wounds healed, the skin tissues can be seen ( FIG. 10 ). The electron microscope slices shows the structures of epidermis, dermis and appendixes (except the hair follicles) ( FIG. 11  and  FIG. 12 ). 
         [0095]    In addition, the pharmaceutical composition  1 ,  3 - 6  also have the same therapeutic effect in the patient (data omitted). 
       Experimental Example 3 
       [0096]    The open fracture wound is often contaminated by the laceration, the wound infection and soft tissue non-healing is a difficult medical problem and the severe patient may facing amputation. This difficult medical problem was solved effectively by the application of the present pharmaceutical composition combined with the current surgical debridement and orthopedic operation. During the Wenchuan Earthquake in 2008, the present pharmaceutical composition was used to treat the patients with open fracture wounds and achieved surprising effects in that the wound healed fast, infection was reduced, and the fracture bone grew fast, effectively avoiding the amputation ( FIG. 13 ). 
         [0097]    After the accident of open fracture, the present pharmaceutical composition  3  was applied on the wounds directly as early as possible. It can not only protect the wounds, isolate the wounds from the air and avoid the contamination, but also play the function of metabolizing the contaminants and debriding the wounds without further damage. The mechanical fixation operation on the fractured bone tissue can be done after cleaning the wounds with normal saline. After the surgical suture of soft tissue and skin, the pharmaceutical composition  3  was applied again on the sutured wounds, which can prevent the infection and promote the wound healing.  FIG. 14  shows the wound conditions after the bone fixation and suture. 
         [0098]    After 40 days treatment, there was no infection on the wounds, the defected skin tissue and other soft tissues were healed ( FIG. 15 ). 
         [0099]    In addition, the present pharmaceutical composition  4  and  5  also achieved the same therapeutic effect on the patients. 
         [0100]    The inventor found that for a pharmaceutical composition with the contents of such raw materials as  Radix Scutellariae, Coptis Chinensis, Cortex Phellodendri, Pericarpium Papaveris  and  Lumbricus  being higher than 6% or lower than 1% by dry weight of the total weight of the sesame oil extract, it has no ideal therapeutic effect on open fracture, especially on the bone recovery. It is speculated that the higher content (higher than 6%) of  Radix Scutellariae, Coptis Chinensis, Cortex Phellodendri, Pericarpium Papaveris  and  Lumbricus  in sesame oil extract may inhibit the cell growth on wounds; and the lower content (lower than 1%) of  Radix Scutellariae, Coptis Chinensis, Cortex Phellodendri, Pericarpium Papaveris  and  Lumbricus  in sesame oil extract does not reach the therapeutic dosage, which cannot promote the cell growth on the wounds. 
       Example 4 
       [0101]    The severe skull electronic burn injury is also a medical problem currently, as there is lack of nutrition sources for the bone tissues, bone tissues are partially defected, and it is difficult to repair the bone tissues by the nutrition supply through bone marrow tissues. The pharmaceutical composition  4  was used directly as the culture media of bone tissues, soft tissues, and skin of the severe electrical burn injury patient combined with skull bone injury, which can directly repair the severe damaged bone tissues and heal the wounds. 
         [0102]    Firstly, under the protection of the pharmaceutical composition  4 , parts of the skull bone necrotic tissues were removed with the surgical debridement ( FIG. 18 ) and X-ray examination shows that most of the bone tissues at the top of skull were defected and the depth of wounds reached to the endomeninx, which indicates that parts of the bone marrow tissues are defected ( FIG. 19 ). 
         [0103]    The pharmaceutical composition  7  and  8  were used as the control drugs for 25 days, there was no obvious improvement at the necrotic skull bone surface. 
         [0104]    Then the bone tissues with partial defect were drilled and the pharmaceutical composition  4  and control drugs were continued to be used to incubate the granulation tissues. The present pharmaceutical composition  4  and control drugs were applied to cover the wounds directly with the thickness of about 1-3 mm and the dressing was changed twice in every morning and night respectively. 
         [0105]    The skull bone of patients has no improvement after using the control drugs and then the pharmaceutical composition  4  was used to continue treatment. 
         [0106]    The wound conditions after using the pharmaceutical composition  4  to incubate the bone tissues and soft tissues in situ were that the surrounding soft tissues were regenerated and the bone tissues surrounded and in the central were growing under the effect of drug ( FIG. 20 ). X-ray image shows that the skull bone in the middle of meninx area was growing under the protection ( FIG. 21 ). 
         [0107]    After 40 days treatment, there was obvious growth of bone tissues and the exposed area of bone membrane became smaller ( FIG. 22 ). 
         [0108]    The treatment was continued until the regenerative restoration in situ of skull bone was realized: the exposed area of bone membrane became smaller and smaller, the regenerative restoration of soft tissues and skin were realized and finally the wound healed ( FIG. 23 ). 
         [0109]    The head skin plastic surgical operation was performed after the healing of the skull bone and wounds, and the hair of the patients can cover most of the head ( FIG. 24 ). 
         [0110]    Same excellent treatment effects can be achieved with the pharmaceutical composition  5  and  6  in the similar tests to the above one. 
       Experimental Example 5 
       [0111]    Male, 29 years old patient was suffering from the severe neck, head, and facial burn injury after carbon monoxide poisoning ( FIG. 25 ). The bone surface of the patient was severe necrotic and there was no granulation tissue growth after regional treatment of surgery and there was no vitality of bone tissue. 
         [0112]    The skull bone of the patient was drilled holes and then iodine treatment was continued for 9 days followed by the application of the pharmaceutical composition  7  and  8  as control drugs for another 10 days, but there was no granulation tissue growth and viable bone tissue ( FIG. 26 ). 
         [0113]    Then, the pharmaceutical composition  5  was used immediately with thickness of 3 mm on the wounds to cover the wounds completely. After 5 days treatment, the necrotic-like bone tissues recovered vitality and the granulation tissues grew out of the drilled holes and the vitality of bone surface recovered and gradually formed periosteum. At this time, the wound was almost ready for skin flap grafting. The granulation tissues were incubated and maintained continuously in the vital environment of bone surface until a proper time was selected for skin flap grafting to cover the entire exposed bones ( FIG. 27  and  FIG. 28 ). 
         [0114]    The free skin flaps from the patient&#39;s back ( FIG. 29  and  FIG. 30 ) was taken for the head skin flap grafting, and the wound of the patient recovered gradually ( FIG. 30 ).
