Objective: To investigate clinicopathologic features and prognosis of adenoid cystic carcinoma (ACC) involving external auditory meatus. Methods: The clinical presentation and follow-up data of 63 patients with ACC of external auditory canal were collected from January 2006 to February 2017 at PLA General Hospital and Hainan Branch of PLA General Hospital. The clinicopathologic features and prognostic factors of external auditory canal ACC were analyzed. Results: (1) There were 28 males and 35 females and the average age of the first diagnosis was 48.9 years (22-81 years). The tumors showed cribriform pattern in 35 cases (15 cases of late stage), tubular pattern in 14 cases (8 cases of late stage), and solid pattern in 14 cases (9 cases of late stage). Cases with solid pattern was relatively more frequent than that of cribriform pattern and tubular pattern, but the difference was not statistically significant (P>0.05). (2) The average follow-up time was 62.4 months (2-228 months) in the 57 available cases. Among the 33 cases with recurrence, 18 cases had local recurrence and 15 cases had distant metastasis. The mean recurrence time was 40.6 months (2-204 months). Nine patients died of ACC: 2 cases in early stage (died at 48 and 102 months after the first treatment), 7 cases in late stage and 57 with (died at 9, 30, 32, 60, 72, 94 and 228 months). (3) Among the 37 patients with perineural invasion, there were 21 cases of cribriform pattern, 4 cases of tubular pattern and 12 cases of solid pattern; the number of cases in early stage and late stage were 15 and 22, respectively; and the differences were statistically significant (P<0.05). In addition, 31 cases had otalgia among the 37 patients with perineural invasion, where differences were not significant (P>0.05). (4) Thirty of 45 cases with tumor resection or partial resection of temporal bone had recurrence, whereas 3 of 12 cases of tumor combined with superficial lobectomy of parotid gland had recurrence. The difference was statistically significant (P<0.05). Postoperative adjuvant radiotherapy was given in 19 cases, including 7 cases of early stage (2 cases of recurrence), and 12 cases of late stage (8 cases of recurrence), among which there was no significant difference (P>0.05). Conclusions ACC occurring in external auditory canal frequently recurs. Superficial parotid lobectomy at the first operation is necessary to prevent tumor recurrence. Postoperative adjuvant radiotherapy has certain curative effect on patients with early stage tumor, but it does not affect the recurrence rate. Patients at late stage are more prone to perineural invasion than those in early stage. In addition, cribriform and solid patterns are more common that tubular pattern, and there is no significant correlation between perineural invasion and otalgia.

Objective To investigate the effect evaluation of nurse manager′s nursing round system on improving ward nursing management level. Methods The self-designed nurse manager′s nursing round observe evaluation form and effect evaluation questionnaire were used to comprehensively evaluate implementation and effects of nurse manager′ s nursing round system. Results The nurse manager′ s nursing round observe evaluation form score was (95. 05 ± 2. 75), the scores of nurse manager′s nursing round system evaluated by patients, nurses and nurse manager were (33. 70 ± 2. 65),(49. 73 ± 0. 98) and (33. 05 ± 3. 86). Multivariate analysis showed that, increase nurses′ attention, increase a sense of security and belonging, enhance the ability of nurses to report illness and critical thinking ability, improve overall care quality can improve evaluation for the system(P < 0. 05). Conclusions The establishment and implementation of nurse manager′s nursing rounds system has improved the wards nursing management level, and patients, nurses and nurse managers give high evaluations for the system.

AIM: To investigate the effect of adalimumab combined with dexamethasone intravitreal implant in the treatment of refractory non-infectious uveitis macular edema(UME).METHODS: A total of 92 cases(131 eyes)of refractory non-infectious UME patients admitted to our hospital from January 2020 to January 2022 were selected and randomly divided into control group, with 46 cases(63 eyes)treated with dexamethasone intravitreal implant and observation group, with 46 cases(68 eyes)treated with adalimumab subcutaneous injection combined with dexamethasone intravitreal implant. The best corrected visual acuity(BCVA), central retinal thickness(CRT), vitreous opacity and Th17/Treg cytokines were measured before and after treatment, and the occurrence of adverse reactions was recorded.RESULTS: Totally 3 cases(4 eyes)were lost to follow-up. After treatment for 1, 3, 6 and 12 mo, BCVA was improved in both groups compared with that before treatment, and CRT, vitreous opacity score, serum interleukin(IL)-17 and IL-22 levels were decreased compared with those before treatment, and serum transforming growth factor-β(TGF-β)and IL-10 levels were increased compared with those before treatment. BCVA in the observation group was better than that in the control group, and CRT, vitreous opacity score, serum IL-17 and IL-22 levels were lower than those in the control group, and serum TGF-β and IL-10 levels were higher than those in the control group(all P<0.05). During treatment and follow-up, no serious adverse reactions occurred in both groups.CONCLUSION: Adalimumab combined with dexamethasone intravitreal implants in the treatment of refractory non-infectious UME can significantly subside the macular edema, reduce vitreous opacity and improve visual acuity.

Objective:To investigate the causes of secondary glaucoma after vitrectomy for familial vitreous amyloidosis associated with transthyretin (TTR) gene Gly83Arg mutation.Methods:A retrospective case study. From January 2008 to January 2020, 13 cases (23 eyes) with hereditary vitreous amyloidosis and treated by vitrectomy in the Affiliated Hospital of Zunyi Medical University were collected. Among them, there were 7 males with 12 eyes and 6 females with 11 eyes. The average age was 43.0±4.8 years. All the affected eyes underwent standard three-channel vitrectomy through the flat part of the ciliary body. According to whether complete vitreous detachment (PVD) was formed during the operation, it was divided into complete PVD group and incomplete PVD group; according to the occurrence time of secondary glaucoma and vitreous amyloidosis after surgery, it was divided into 1-12 months group and 13-36 months group, >37 months group. The average follow-up time after surgery was 36.7±6.0 months. The incidence of secondary glaucoma and the recurrence rate of vitreous amyloidosis between groups were compared by χ2 test; the correlation between recurrence of vitreous amyloidosis and secondary glaucoma after surgery was analyzed by Spearman rank correlation analysis. Results:Among the 23 eyes, there were 8 eyes in the complete PVD group and 15 eyes in the incomplete PVD group, respectively. Vitreous amyloidosis recurred in 15 eyes (65.22%, 15/23) after surgery. There were 14 (93.30%, 14/15) and 1 (6.70%, 1/15) eyes in the incomplete PVD group and the complete PVD group, respectively; the comparison of the recurrence rate of vitreous amyloidosis between the two groups was statistically significant ( χ2=11.676, P<0.01). 1-12 months group, 13-36 months group, >37 months group included 1 (4.35%, 1/23), 12 (52.17%, 12/23), 2 (8.70%, 2/23) Only eye. The recurrence rate in the 13-36 months group was significantly higher than that in the 1-12 months group and >37 month group. Secondary glaucoma occurred in 11 eyes (47.80%, 11/23) after surgery. 1-12 months group, 13-36 months group, above 37 months group were 1 (4.35%, 1/23), 8 (34.78%, 8/23), 2 (8.70%, 2/23) eyes. The incidence of secondary glaucoma in the 13-36 months group was higher than that in the 1-12 months group and >37 months group. Among 11 eyes with secondary glaucoma, 10 eyes had recurrence of vitreous amyloidosis after surgery, and 1 eye had no recurrence. The results of Spearman rank correlation analysis showed that there was a positive correlation between the recurrence of vitreous amyloidosis and the occurrence of secondary glaucoma ( rs=0.516, P=0.012). Conclusion:The incidence of secondary glaucoma after vitrectomy in a family with vitreous amyloidosis caused by the Gly83Arg mutation of TTR gene is higher, and its occurrence is significantly positively correlated with the recurrence of vitreous amyloidosis.
