Objective To analyze the expression of serum mannose binding lectin associated serine protease 1(MASP1)and protein kinase D2(PRKD2)in locally advanced cervical cancer(LACC)patients,and their relationship with the efficacy of neoadjuvant chemotherapy(NACT).Methods The clinical data of 98 LACC patients(LACC group)treated with NACT in the hospital from March 2019 to April 2021 were retrospective-ly selected,and they were divided into effective group(n=76)and ineffective group(n=22)according to the efficacy.Fifty patients with early cervical cancer diagnosed and treated in the same period were selected as the early cervical cancer group,and 50 female health examination subjects were selected as the healthy control group.Enzyme-linked immunosorbent assay was applied to detect serum levels of MASP1 and PRKD2.Logis-tic regression analysis was applied to analyze the influencing factors of NACT efficacy.The evaluation value of serum MASP1 and PRKD2 on the efficacy of NACT were analyzed by the receiver operating characteristic curve.Results The serum levels of MASP1 and PRKD2 in the LACC group were higher than those in the ear-ly cervical cancer group and the control group,and the differences were statistically significant(P＜0.05).The serum levels of MASP1 and PRKD2 in LACC group were correlated with International Federation of Gy-necology and Obstetrics(FIGO)stage and pathological grade,and the serum levels of MASP1 and PRKD2 in patients with FIGO stage Ⅲ and pathological grade G3 were higher(P＜0.05).FIGO stage Ⅲ proportion,se-rum MASP1 and serum PRKD2 levels in NACT ineffective group were higher than those in effective group(P＜0.05).FIGO stage Ⅲ,serum MASP1 and serum PRKD2 were independent risk factors for NACT efficacy in LACC patients(P＜0.05).The area under the curve of serum MASP1 and PRKD2 combined to evaluate the efficacy of NACT was 0.883(95％CI:0.828-0.935),which was larger than 0.802(95％CI:0.761-0.846)and 0.825(95％CI:0.764-0.852)predicted by the single index,and the difference were statistically significant(Z=4.111,5.012,both P＜0.001).Conclusion Level of serum MASP1 and PRKD2 in LACC pa-tients are increase,which are independent risk factors affecting the efficacy of NACT.Combined detection of MASP1 and PRKD2 has high predictive value for NACT efficacy.

Objective To study the prognostic factors of progressive hearing loss among children with large vestibular aqueduct syndrome(LVAS).Methods The clinical data of 49 children(95 ears)with LVAS who re-ceived at least two hearing tests from January 2017 to January 2023 in our hospital were retrospectively analyzed,and they were divided into two groups according to the progression of hearing loss:the stable group(55 ears)and the progressive group(40 ears).The effects for progressive hearing loss of initial age,gender,laterality,imaging features,audiometric data,and incomplete partition type Ⅱ(IP-Ⅱ)and SLC26A4(type A,B,C,D)genotypes were analyzed by univariate and multivariate Cox regression analysis.The potential prognostic factors were further verified by Kaplan-Meier survival analysis.Results Each dB decrease in the initial average hearing threshold in-creased the expected hazard by 7.03％(P=0.02).Incomplete partition type Ⅱ(IP-Ⅱ)was associated with 5.11 hazard ratio(95％CI,1.81 to 14.45,P=0.002).Genotype C was associated with 6.13 hazard ratio for progressive hearing loss(95％CI,2.07 to 18.13,P=0.001).Conclusion The initial average hearing threshold,IP-Ⅱ,and SLC26A4 genotype C were significant effect factors of progressive hearing loss in patients with LVAS.This could predict the progression of hearing loss in children with LVAS and help identify patients at high risk for progressive hearing loss.

Objective To analyze the correlation between the fractional exhaled nitric oxide (FeNO) levels and blood eosinophil (EOS) count and the frequency of wheeze in infants with recurrent wheezing.Methods From February 2015 to August 2016 in the General Hospital of Northern War Zone,outpatient department of Pediatrics treatment and hospitalization of age less than or equal to 3 year old children with recurrent wheezing,101 cases were induded as the research object.On the basis of asthma predictive index (API) score were divided into API positive group (n =55) and API negative group (n =46),according to the wheeze frequency of the two groups children were divided into 3 ～ 4 times wheezing groups and more than 5 times.Select 37 cases of healthy children as control group.The concentration of FeNO and blood EOS count are detected in all the children.The correlation between the three groups of children with FeNO concentration,the correlation between FeNO and blood EOS count,the correlation between the the frequency of wheeze and FeNO in experimental groups were analyzed.Results (1) API positive group mean FeNO (19.3 ± 6.2) ppb was significantly higher than API negative group (7.7 ± 2.9) ppb,there was no difference (P ＞ 0.05).API negative group mean FeNO (7.7 ± 2.9) ppb is lower than the normal control group (9.5 ± 2.0) ppb,there was no difference (P ＞0.05).(2) API positive group mean EOS count (124.7 ± 1.6) x 106/L is higher than API negative group (86.1 ± 1.9) x 106/L,there was significant difference (P ＜ 0.01);(3) There was a correlation between FeNO level and blood EOS count in API positive group,there was no correlation between FeNO level and blood EOS count in API negative group and con~ol group.(4) No statistical differences were found in ≤4 times wheezing groups and more than 5 times of the mean FeNO.Conclusion There is no significant difference in the mean value of FeNO between different times of wheezing in children with recurrent wheezing.The combination of medical history,EOS,FeNO and API might be used to predict the wheezing episode of infants.

Objective To study the incidence of acute renal injury ( AKI), related clinical risk factors and recent prognosis in critically ill neonates. Methods The study was a retrospective analysis from January 2016 to December 2016 in the neonatal care department of General Hospital of Shenyang Military Region and the First Hospital Affiliated to China Medical University. We collected the perinatal data,clinical data,biochemical indexes and short-term prognosis. Logistic regression analysis was used to identify the risk factors. Results The incidence of AKI in critically ill neonates was 13. 11%(32/244),and the probability of poor prognosis was 62. 50%(20/32). Gestational age,birth weight,1 min and 5 min Apgar score,con-sciousness,mechanical ventilation,blood pH,blood glucose,blood urea nitrogen,white blood cell and red cell distribution width were the related factors for AKI in critically ill neonates. Logistic regression analysis showed that consciousness(OR=4. 542,95%CI 1. 176-17. 539,P=0. 028),mechanical ventilation(OR=0.267,95%CI 0.101-0.705,P = 0.008),5 min Apgar score(OR = 0.750,95% CI 0.605-0.930,P =0. 009),blood urea nitrogen value(OR=1. 074,95%CI 1. 006-1. 146,P=0. 030)were identified as the inde-pendent risk factors of AKI. ConclusionThe incidence of AKI is high in critically ill neonates. Consciousness,mechanical ventilation,5 min Apgar score,blood urea nitrogen value are identified as independent risk factors for AKI.
