OBJECTIVE: To investigate the utilization of functional surgery in benign parotid tumor of superficial lobe. METHOD: Conventional parotidectomy were modified in the following aspects: incision, preservation of great auricular nerve, local facial nerve dissection, partial superficial parotidectomy and repairing of sunken deformity. The post-operative recurrence incidence, functional outcomes and complications of 21 patients with benign parotid tumor of superficial lobe undergoing functional surgery were analyzed retrospectively. RESULT: No recurrence of tumor was found in follow-ups. No obvious scar and sunken deformity was found. The area with abnormal sensory around the auricle was smaller compared with those whose great auricular nerve had not been preserved. Post-operative transient facial paralysis was observed in 4 cases and all recovered in 3 months. One case complained about Frey's syndrome. Salivary leakage was found on 1 case. CONCLUSION Compared with conventional surgery, functional surgery for benign parotid tumor of superficial lobe may improve cosmetic, sensory, salivary function, facial nerve function and quality of life without raising post-operative recurrence.

OBJECTIVE: To study the expressions and clinical significance of integrin beta1 and integrin-linked kinase(ILK) in laryngeal carcinoma (LSCC). METHOD: The mRNA and protein levels of integrinbeta1 and integrin-linked kinase in 43 specimens of laryngeal carcinoma, its surrounding tissue and 18 specimens of vocal cord polyp were detected by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry SABC method. RESULT: The mRNA levels of integrin beta1 and ILK protein were significantly higher in laryngeal carcinoma than that in its surrounding tissue and vocal cord polyp (P < 0.05). There was significant correlation between the levels of integrin beta1 expression and the status of cervical lymph node, either between the level of ILK expression and cervical lymph node status (P < 0.05). There was significant correlation between the levels of integrin beta1 expression and T-category, either between the level of ILK expression and T-category (P < 0.05). But pathological grades was not significantly related with the level of integrin beta1 or ILK expression (P > 0.05). CONCLUSION The expressions of integrin beta1 and ILK are increased in LSCC. Integrin beta1 and ILK may contribute significantly to invasion and metastasis of LSCC.

Objective To explore the effects of probiotics on intestinal function, nutritional status and inflammatory response in critically ill patients with enteral nutrition (EN) support. Methods A total of 90 critically ill patients admitted to Intensive Care Unit (ICU) of the First Affiliated Hospital of Anhui Medical University from July 2016 to November 2018 were enrolled, and they were divided into a probiotics combined with EN group (27 cases) and an simple EN group (63 cases) according to random number table method. The patients in the simple EN group were treated with conventional nutrient preparations such as fresubin or fresubin energy fibre; the patients in probiotics combined with EN group were supplemented with probiotics on the basis of conventional EN support for consecutive 7 days in both groups. The changes of gastrointestinal function, nutritional index and inflammatory response index after treatment were observed in both groups. Results After treatment, the subjective global assessment (SGA) method was used to identify the gradation of the patients, it was shown that the proportion of SGA-B grade patients in simple EN group had an upward trend; while the proportion of SGA-B grade patients in probiotics combined with EN group had no significant change; and there was no significant difference in the proportion of SGA-B patients between simple EN group and probiotics combined with EN group after treatment [20.6% (13/63) vs. 7.4% (2/27),P > 0.05]. Compared with those before treatment, the levels of hemoglobin (Hb), white blood cell count (WBC), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukins (IL-6, IL-12) in both groups were significantly decreased, while the levels of albumin (Alb), pre-albumin (PA), total lymphocyte count (TLC) in both groups were increased after treatment, and the changes of Hb, TNF-α, IL-6 in probiotics combined with EN group were more significant than those in the simple EN group [Hb (g/L): 95.0 (78.0, 107.0) vs. 93.0 (80.0, 107.0), TNF-α (pg/L): 21.2±4.0 vs. 28.0±5.7, IL-6 (pg/L): 161.3±37.6 vs. 186.2±51.8];the differences in levels of Hb, CRP, TNF-α before and after treatment between the probiotics combined with EN group and simple EN group were statistically significant [Hb (g/L): 1.0 (-4.0, 12.0) vs. 11.0 (1.0, 20.0), CRP (mg/L): 44.3 (13.7, 57.7) vs. 7.5 (-20.1, 62.4), TNF-α (pg/L): 13.3±6.3 vs. 7.9±5.5, all P < 0.05]. There were no statistical significant differences in the other indicators between the two groups (all P > 0.05). Conclusion Probiotics can improve the gastrointestinal function and inflammatory status of critically ill patients with EN support, regretfully, in a short term, the improvement of nutritional status of such patients is not obvious, but probiotics has certain significance in preventing the risk of aggravation of malnutrition and reduction of Hb level.
