BACKGROUND: Myelin sheath related inhibitors have been found to have great impact on microenvironment of axon regeneration. Traditional Chinese medicine is gradual y becoming a research hotspot on improving microenvironment of nerve regeneration with its advantage on multiple factors and targets.
OBJECTIVE: To clarify the effect of Jisuikang on Nogo-66 receptor NgR expression after spinal cord injury.
METHODS: 144 rats were randomly divided into six groups: sham surgery group, model group, prednisone group, high-, moderate- and low-dose Jisuikang groups (n=24). Animal models of spinal cord injury were established by the modified Allen’s method in the later five groups. Rats in the prednisone group were daily given 0.06 g/kg prednisone acetate by lavage, once a day. Rats in the high-, moderate- and low-dose Jisuikang groups were daily intragastrically given 12.5, 25 and 50 g/kg Jisuikang, once a day. Rats in the sham surgery and model groups were intragastrically daily given 20 mL of saline, once a day. Rats in each group were administered drugs until death.
RESULTS AND CONCLUSION: Compared with the model group, NgR protein and mRNA expression levels were significantly lower in the prednisone, moderate-and low-dose Jisuikang groups. These data suggested that Jisuikang can improve the recovery of neurological function after spinal cord injury and effectively inhibit NgR protein expression at the site of injury so as to suppress the microenvironment factors harmful to nerve regeneration and further improve the microenvironment of nerve regeneration.

The ectopic salivary gland refers to the presence of salivary gland tissue in an area other than the site where salivary glands normally exist. They often occur near the line connecting the external ear canal and the medial border of the clavicle. It is extremely rare to occur in the urogenital system. This paper retrospectively analyzed the clinicopathological data of a patient with ectopic salivary glands accidentally discovered due to testicular torsion. Patients are generally asymptomatic. If there is no fistula leading to the skin or mucosal surface, it is difficult to find clinically. The diagnosis depends on postoperative pathological examination. For ectopic salivary glands, surgery is required regardless of the location.

Surgery is an important means of clinical treatment of thyroid diseases. For thyroid diseases that have failed conservative treatment, surgical treatment is recommended. With the maturation of thyroid endoscopy technology and the increasing demand for cosmetic surgery, more and more thyroid endoscopic surgeries are being performed. Endoscopic thyroid surgery has the advantages of small incision, less bleeding, less postoperative complications, less scar tissue, and so on, which has been clinically recognized and approved. Although endoscopic surgery has achieved remarkable results in the treatment of thyroid diseases, how to effectively protect the parathyroid gland during surgery and avoid hypothyroidism is one of the difficulties that surgeons pay attention to. In this paper, the identification and protection techniques of the parathyroid gland during endoscopic thyroid surgery were analyzed, and summarized, in order to provide a reference for improving the protection techniques of the parathyroid gland during endoscopic thyroid surgery.
