Objective To discuss the diagnostic value of branchial cleft fistula with CT and(or)MRI.Methods CT and(or)MRI findings of 33 cases of branchial cleft fistula were collected and analyzed retrospectively.Results Branchial cleft fistula were divided into four types namely first,second,third and fourth according to its origin with each type having its own corresponding CT and MRI features.Among the 33 cases,7 cases (21%)were first branchial cleft fistula,which originated from external auditory meatus and the parotid gland.These lesions presented as a tubular structure around the ear,sometimes invading the facial nerve,causing facial nerve symptoms.1 8 cases (5 5 %)were second branchial cleft fistula,and were presented as tubular ones in the anterior triangle area of the neck or along the anterior border of the sternocleidomastoid muscle.8 cases (24%)were third or fourth branchial cleft fistula,which were difficult to differentiate,both of them originated from pyriform sinus and partly penetrated the thyroid.Conclusion CT and(or) MRI could show the location and range of the lesion clearly,making it valuable for diagnosis of branchial cleft fistula.

Objective:To explore the risk factors of postpartum sepsis and provide references for clinical prevention of postpartum sepsis.Methods:The clinical data of postpartum patients who were treated and delivered in the maternity ward of Shengjing Hospital Affiliated of China Medical University from January 2016 to December 2018 were analyzed retrospectively. Among them, 99 patients with postpartum sepsis were assigned to the case group and 212 patients without postpartum sepsis in the same period were selected with a simple random method and as the control group. The clinical data of the two groups were collected by consulting the hospital electronic medical record system. Single factor and multivariate Logistic regression were applied to analyze the risk factors of postpartum sepsis.Results:The infection sites of 99 postpartum sepsis patients were mainly genital tract and respiratory system, accounting for 28.28% (28/99) and 26.26% (26/99), respectively. In blood culture of 99 cases of postpartum sepsis patients, 58.59% (58/99) pathogens of Gram-positive bacteria were detected with the highest proportion, among which Streptococcus was mainly, accounting for 23.23%(23/99). The proportion of Gram-negative bacteria was 38.38%(38/99), and Escherichia coli was mainly, accounting for 31.31% (31/99). Multivariate Logistic analysis showed that gestational diabetes ( OR = 2.643, 95% CI 1.123 - 6.276), genital tract infection ( OR = 7.542, 95% CI 3.571-15.959), vaginal trial (switch to cesarean section) ( OR = 1.218, 95% CI 1.008-1.493), premature rupture of membranes ( OR = 1.152, 95% CI 1.019 - 1.449), postpartum hemorrhage ( OR = 1.562, 95% CI 1.263 -1.881) and cesarean delivery ( OR = 2.074, 95% CI 1.442 - 2.993) were the risk factors of postpartum sepsis. Conclusions:The main risk factors affecting postpartum sepsis includes gestational diabetes, genital tract infection, vaginal trial (switch to cesarean section), premature rupture of membranes, postpartum hemorrhage and cesarean delivery. It is necessary to take corresponding intervention measures to strengthen prevention of these risk factors, which is of great significance for prevention and treatment of postpartum sepsis.

Objective to investigate the clinical effect of constant temperature vaginal mould in preventing vaginal stricture in patients with cervical cancer treated with radiotherapy. Methods from January 2017 to December 2018, 80 patients with cervical cancer were selected and divided into vaginal irrigation control group (n = 40) and observation group (n = 40). The incidence of vaginal stricture was compared between the two groups. Results the incidence of vaginal stenosis was 32.50% in the observation group and 70.00% in the control group (P < 0.05). Conclusion vaginal mould is helpful to reduce the incidence of vaginal stenosis caused by external irradiation and close irradiation, which is worth popularizing in the future.
