Effects of oleanolic acid on immunoregulation were investigated in mice on the molecular level. Results showed that oleanolic acid could stimulate the biosynthesis or release of prostaglandins E2, F2? ( PGE2, PGF2? ) and cAMP, whereas had an inhibitory action on cGMP and histamine. Prostaglandins, cyclic nucleotides and histamine participate in many bodily functions, including regulation of blood pressure, immune function. It is suggested that their interaction may be of potential importance as a possible mechanism by which oleanolic acid acts in disease.

Experimental studies were made on enhancing effect of aloperine on PG-cyclooxyge-nase activity. Radioimmunoassay for determination of PGE2 and PGF2? contents was employed to evaluate PG-cyclooxygenase activity. Mice were given aloperine (50mg ? kg ? d-1) ip for 7d and the effects of lung and kidney homogenates on extrogenous arachidonic acid were studied. The results suggest that biosynthesis of PGE2, PGF2? be obviously increased in the experimental than that of control, suggesting of aloperine showing enhancing effect on PG-cyclooxygenase activity.

The blockade of targeted immune checkpoint is one of the most promising approaches to activate therapeutic antitu-mor immunity. The immune checkpoint refers to a plethora of inhibitory pathways in the immune system. These pathways are crucial for maintaining self-tolerance and modulating the duration and amplitude of physiological immune responses in peripheral tissues to minimize collateral tissue damage. Tumors co-opt certain immune-checkpoint pathways as a major mechanism of immune resistance. Cytotoxic T-lymphocyte-associated antigen 4 antibodies were the first of this class of immunotherapeutics to acquire approval from the US Food and Drug Administration. Preliminary clinical findings with blockers of additional immune-checkpoint proteins, such as pro-grammed cell death protein 1, indicate broad and diverse opportunities to enhance anti-tumor immunity with the potential to produce du-rable clinical responses. Classic chemotherapy exerts significant immunomodulatory effects on tumor cells via multiple mechanisms. Therefore, the combination of immunotherapy, including immune checkpoint blockade with chemotherapy, is a new promising trend in anti-tumor immunotherapy.

OBJECTIVE: To evaluate the influence of endoscopic sinus surgery on olfactory disorder caused by chronic sinusitis and nasal polyps, by testing the olfactory function of seventy-four patients before and after endoscopic sinus surgery,and evaluate the outcomes of olfactory dysfunction after endoscopic sinus surgery in patients with choinc rhinosinusitis and the related factors. METHOD: The olfactory function of the seventy-four patients with chronic sinusitis and nasal polyps were tested by the T&T olfactory testing method at pre-operation and four weeks,twelve weeks, twenty-four weeks of post-operation. Patients were divided into two groups, according to whether combined with allergic rhinitis. Data were achieved by the scores of endoscopic appearances of Kennedy, and CT staging system of Lund-Mackey. Parallel processing standard endoscopic operation and processing specification during peri operation period. Analysing the degree of olfactory rehabilitation in chronic sinusitis and nasal polyps with allergic rhinitis. RESULT: (1) Compared with the level of olfactory function, significant improvement was found at first month;however, the olfactory function level 4 weeks after operations was significantly statistically different with that 12 weeks and 24 weeks after operations; (2) Lund-Mackey sinus CT higher score is related to the worse degree of postoperative nasal olfactory rehabilitation (P < 0.05). (3) The higher scores of endoscopic appearances of Kennedy is related to the worse degree of postoperative nasal olfactory rehabilitation (P < 0.05). (4) Allergic rhinitis is one of the factors of olfactory rehabilitation in chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation, the olfactory rehabilitation of patients with allergic rhinitis is worse than that in the patients with no allergic rhinitis. (5) Course of disease is one of the factors of chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation. Longer the course of disease, worse the olfactory rehabilitation. (6) E osinophil count was related to olfactory rehabilitation in chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation. Higher Eosinophil count, worse the olfactory rehabilitation. CONCLUSION FESS plays a positive role in the improvement of olfactory impairment in patients with CRS. It is important to protect the olfactory mucous during surgical removal of sinonasal lesions. The standard intraoperative procedure, treatment on allergic rhinitis and regular follow-up after operation are also very important.
