Objective To investigate the correlation between peripheral serum TNF-α and TGF-β1 expression levels with the infiltration degree of lymphocytes in labial glands and interstitial lung disease(ILD) in the patients with primary Sjogren's syndrome (pSS).Methods Serum level of TNF-α and TGF-β1 in 116 patients with pSS and 20 persons undergoing physical examination were measured by ELISA.Meanwhile the labial gland samples in pSS patients were performed the pathological examination.The patients were grouped according to the lesion stage of ILD and pathology grade of labial glands.The serum TNF-α and TGF-β1 levels were statistically analyzed.Results Serum levels of TNF-α and TGF-β1 in the pSS-ILD group were significantly higher than those in the simple pSS group and control group(P＜0.01).The levels of serum TNF-α and TGF-β1 in the simple pSS group were significantly higher than those in the control group(P＜0.01).The levels of serum TNF-α and TGF-β1 in the labial glands lymphocytes infiltration group were significantly higher than those in the labial glands lymphocytes non-infiltration group and control group(P＜0.01),while the levels of serum TNF-α and TGF-β1 in the labial glands lymphocytes non-infiltration group were significantly higher than those in the control group(P＜0.01).The TNF-α and TGF-β1 expression was positively correlated with lymphocytes infiltration lesion grade(r=0.867,0.613,P=0.000);the expression of TNF-α and TGF-β1 was positively correlated with the lesion grade of ILD(r=0.814,0.864,P =0.000);the level of TNF-α was positively correlated with the TGF-β1 relative expression amount(r=0.857,P=0.000).Conclusion TNF-α and TGF-β1 are involved in the lymphocytes infiltration of labial glands and ILD occurrence and develvp ment,and their expression increase may be the cause of labial glands structure destruction and complicating ILD.

Objective:To investigate the status of postoperative sore throat and hoarseness in patients undergoing general anesthesia with double-lumen endotracheal intubation and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 129 patients with double-lumen endotracheal intubation who underwent elective surgery in a Class Ⅲ Grade A general hospital in Wuhan in Hubei Province from July to December 2020 were selected as the research objects. The general information questionnaire, Visual Analogue Scale (VAS), Labial and Tongue Mucosa Scale and Hoarse Voice Scale were used to investigate the patients.Results:The incidence of sore throat in 129 patients with double-lumen endotracheal intubation at 1, 6, 24, 48 and 72 hours after surgery were 68.22%, 44.96%, 76.74%, 64.34% and 48.84%, respectively. Among them, the incidences of sore throat in resting state were respectively 10.9%, 6.2%, 1.6%, 0 and 1.6%, incidences of sore throat in swallowing state were respectively 18.6%, 8.5%, 3.1%, 0 and 0, and the incidences of hoarseness were respectively 66.67%, 45.74%, 78.29%, 65.89% and 48.84%. There were statistically significant differences in the occurrence of hoarseness in patients of different ages and preoperative fasting time 1 hour after extubation ( t=2.499, 2.106; P<0.05). The VAS scores of patients with hoarseness in resting state and swallowing state were higher than those in patients without hoarseness, and the differences were statistically significant ( t=3.688, 2.818; P<0.01). Correlation analysis showed that hoarseness was negatively correlated with the condition of lip and tongue mucosa ( r=-0.309, P<0.01) . Conclusions:The incidence of postoperative throat pain in patients undergoing general anesthesia with double-lumen endotracheal intubation is high. With the extension of time, pain can be gradually relieved. The self-healing effect of hoarseness over time is not ideal. Advanced age, prolonged water fasting before operation and dry lip and tongue mucosa are the influencing factors of postoperative sore throat. Early identification and effective measures should be given in nursing evaluation to reduce the occurrence of postoperative sore throat.
