OBJECTIVE: To investigate the myeloid differentiation factor 88 (MyD88) expression in laryngeal carcinoma and its clinical significance. METHOD: Fifty-one patients with laryngeal carcinoma were collected, and all patients were confirmed by pathological diagnosis results. The expression of MyD88 protein was detected by immunohistochemical method in laryngeal cancer and its adjacent tissues to investigate the correlation among MyD88 expression, clinicopathological characteristics and prognosis of patients. RESULT: The positive expression rate of MyD88 in laryngeal cancer tissues was 68.6%, significantly higher than that in normal tissues adjacent to carcinoma of which positive expression rate was 11.8%; MyD88 positive rate had nothing to do with laryngeal cancer patients age, sex, differentiation and tumour location (all P > 0.05), but correlated with clinical stage (P < 0.01) and lymph node metastasis (P < 0.05). In addition, the study also found that the expression of MyD88 quantity was inversely proportional with the five-year survival rate. The survival rate of patients with higher expression of MyD88 was significantly lower than that of patients with lower expression (P < 0.05). CONCLUSION MyD88 may be an important participant in the pathogenesis of laryngeal carcinoma, MyD88 targeted therapy may improve the prognosis of patients with laryngeal cancer.

Objective:To evaluate the clinical efficacy of neck pricking combined with oral pricking in the treatment of dysphagia after stroke.Methods:Seventy-four patients with post-stroke dysphagia who met the inclusion criteria were randomly divided into the treatment group (acupuncture + rehabilitation training group) and the control group (rehabilitation training group) according to random number table method, 37 cases for each group. Both groups of patients were given conventional drug therapy and rehabilitation of Chinese and Western medicine. On this basis, the control group used swallowing rehabilitation training. The treatment group used acupuncture combined with neck pricking and oral pricking based on swallowing rehabilitation training. Both groups were treated for 3 weeks. Before and after the treatment, three different traits of sputum (liquid, mushy and paste) videofluoroscopic swallowing study (VFSS) were observed for each patient, and the swallowing conditions were observed. The primary outcome measures were the oral swallowing scale score, the pharyngeal swallowing scale score, the Rosenbek infiltration/aspiration scale score, and the standard swallowing function rating scale (SSA). The improvement in swallowing function and aspiration was compared between the two groups.Results:After treatment, the SSA score of the treatment group (25.05 ± 5.27 vs. 28.66 ± 5.33, t=2.884) was lower than that of the control group ( P<0.05). Compared with the same group before treatment, treatment group and control group of oral stage VFSS liquid ( t=5.199, 5.413), mushy ( t=4.761, 4.824) and pasty ( t=5.295, 4.428) scores, throat stage liquid ( t=4.986, 3.919), mushy ( t=4.789, 4.170) and pasty ( t=4.136, 3.673) scores were increased ( P<0.01), but there was no statistically significant difference between the groups ( P>0.05). After treatment, Rosenbek's leakage-aspiration degree classification was significantly reduced ( Z values were 4.224, 2.956, all Ps<0.01), but there was no statistically significant difference between the groups ( P>0.05). The total effective rate was 89.2% (33/37) in the treatment group and 74.3% (26/35) in the control group. There was no statistically significant difference between the two groups ( Z=1.125, P=0.261). Conclusions:Neck pricking combined with oral pricking and rehabilitation training for stroke dysphagia is better than simple rehabilitation training, and could significantly improve swallowing-feeding function, which could be promoted in clinical rehabilitation.
