In order to clarify the cellulose-utilizing mechanism of the Cerambycidae, the microorganism in the Apriona germari(Hope) larvae's gut was cultured and identified. A strain of facultative anaerobic cellulose-utilizing bacteria was isolated from the midgut fluid of A. germari larvae with the cellulose-congo red agar medium. The colonies of the bacteria were white and round with regular margin. Clear zones of cellulolysis surrounding the colonies might reach 10m～20mm. The size of the bacteria was 0.5μm～0. 8μm× l～3μm approximately. The cell was gram-positive rod with polar flagella. It hadn't spores. With the results of biochemical tests, the bacteria were tentatively identified as Cellulomonas.

OBJECTIVE: To review the research progress in biotherapy of rotator cuff injury in recent years, in order to provide help for clinical decision-making of rotator cuff injury treatment. METHODS: The literature related to biotherapy of rotator cuff injury at home and abroad in recent years was widely reviewed, and the mechanism and efficacy of biotherapy for rotator cuff injury were summarized from the aspects of platelet-rich plasma (PRP), growth factors, stem cells, and exosomes. RESULTS: In order to relieve patients' pain, improve upper limb function, and improve quality of life, the treatment of rotator cuff injury experienced an important change from conservative treatment to open surgery to arthroscopic rotator cuff repair. Arthroscopic rotator cuff repair plus a variety of biotherapy methods have become the mainstream of clinical treatment. All kinds of biotherapy methods have ideal mid- and long-term effectiveness in the repair of rotator cuff injury. The biotherapy method to promote the healing of rotator cuff injury is controversial and needs to be further studied. CONCLUSION All kinds of biotherapy methods show a good effect on the repair of rotator cuff injury. It will be an important research direction to further develop new biotherapy technology and verify its effectiveness.
