Objective:To investigate the influencing factors for postoperative deep vein thrombosis in elderly patients with inguinal hernia.Methods:The retrospective case-control study was conducted. The clinical data of 352 elderly patients with inguinal hernia who were admitted to the Affiliated Hospital of Jining Medical College from March 2018 to March 2021 were collected. There were 325 males and 27 females, aged (72±3)years. Observation indicators: (1) treatment and follow-up; (2) analysis of influencing factors for postoperative deep vein thrombosis. Follow-up was conducted using outpatient examination and telephone interview to detect occurrence of deep vein thrombosis in patients up to September 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The univariate analysis was conducted using the corresponding statistical methods based on data type. The Logistic regression model was used for multivariate analysis. Results:(1) Treatment and follow-up. Of the 352 inguinal hernia patients, there were 18 cases with irreducible hernia and 334 cases with reducible hernia. All the 352 patients underwent laparoscopic hernio-rrhaphy successfully, including 95 cases with totally extraperitoneal prosthetic, 257 cases with transabdominal preperitoneal prosthesis. The operation time and volume of intraoperative blood loss of the 352 patients were (70±7)minutes and (8.0±1.5)mL, respectively. There were 39 cases with intraoperative blood transfusion and 313 cases without intraoperative blood transfusion, 167 cases with common patch, 185 cases with light patch. The compression time of operative area, time to first out-of-bed activities, duration of postoperative hospital stay of the 352 patients were (19.7±2.9)hours, (5.6±1.8)hours, (3.0±1.9)days, respectively. All the 352 patients were followed up for 6 months after operation. During the follow-up, there were 7 patients with deep vein thrombosis. (2) Analysis of influencing factors for postoperative deep vein thrombosis. Results of univariate analysis showed that age, body mass index, smoking history, alcoholism history, hypertension, chronic obstructive pulmonary disease, coronary heart disease, cerebrovascular disease, varicose veins, intraoperative blood transfusion, time to postoperative first out-of-bed activities, duration of postoperative hospital stay were related factors for postoperative deep vein thrombosis in elderly patients with inguinal hernia ( t=2.19, 2.06, χ2=9.86, 9.02, 7.90, 14.36, 17.12, 36.25, 28.27, 7.32, t=3.30, 3.04, P<0.05). Results of multivariate analysis showed that age, hypertension, chronic obstruc-tive pulmonary disease, coronary heart disease, cerebrovascular disease, varicose veins, intraopera-tive blood transfusion, time to postoperative first out-of-bed activities, duration of postoperative hospital stay were independent influencing factors for postoperative deep vein thrombosis in elderly patients with inguinal hernia ( odds ratio=4.32, 5.95, 6.44, 15.85, 9.63, 7.61, 9.88, 7.27, 7.96, 95% confidence intervals as 0.92?8.72, 4.45?12.74, 1.74?19.46, 3.97?36.84, 4.95?16.26, 2.65?18.03, 3.50?21.47, 1.48?16.37, 2.08?14.73, P<0.05). Conclusion:Age, hypertension, chronic obstructive pulmonary disease, coronary heart disease, cerebrovascular disease, varicose veins, intraoperative blood transfusion, time to postoperative first out-of-bed activities, duration of postoperative hospital stay are independent influencing factors for postoperative deep vein thrombosis in elderly patients with inguinal hernia.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with non-syndromic hearing loss (NSHL). METHODS: Commercialized gene chip was applied to detect common mutations associated with congenital deafness. Whole exome sequencing was carried out for patients for whom gene chip yielded a negative result. Candidate variants were verified by Sanger sequencing. RESULTS: Two patients from the pedigree were discovered to carry compound heterozygous variants of the TRIOBP gene, namely c.3299C>A and c.5185-2A>G. Their parents had normal hearing and were both heterozygous carriers of the above variants. Both variants had co-segregated with the disease phenotype in the pedigree and were unreported previously. CONCLUSION Pathogenic variants of the TRIOBP gene comprise an important factor for NSHL. The novel c.5185-2A>G and c.3299C>A variants discovered in this study have enriched the mutational spectrum of the TRIOBP gene and enabled molecular diagnosis and genetic counseling for the family.

Objective Tostudytheeffectsoftitanicartificialossiclereplacementincanalwall - downandcanalwall-up tympanoplasty for patients suffering from chronic otitis media .Methods A total of 157 cases (164 ears) un-derwent canal wall-down and canal wall -up tympanoplasty at our hospital from Feburary 2014 to Feburary 2016 were retrospectively analyzed ,in which 50 cases in canal wall down tympanoplasty with titanic ossicle replacement , 49 cases without replacement ,42 cases in canal wall -up tympanoplasty with titanic artificial ossicle replacement , and 23 cases without replacement .The average air bone gaps (ABG) before and 3 months after operations were re-corded and the average reduced ABGs were compared between sub -groups to evaluate the effects of titanic artificial ossicle replacement .Results In the canal wall-down tympanoplasty group ,the mean ABGs of 3 months after oper-ations in the replacement subgroup was 15 .72 ± 11 .18 dB ,the reduced ABGs was 17 .45 ± 5 .23 dB ,and the impro-ving rate for hearing was 71 .54％ ,statistically higher than the non -replacement subgroup(P<0 .05) .In the canal wall-up tympanoplasty group ,the mean ABGs of 3 months after operations in the replacement subgroup was 8 .13 ± 5 .37 dB ,the reduced ABGs was 26 .85 ± 11 .03 dB ,the improving rate for hearing was 75 .12％ ,statistically higher than non-replacement subgroup(P<0 .05) .Conclusion The replacement of titanic artificial ossicle in both of canal wall-down and canal wall-up tympanoplasty is helpful to improve hearing .

Objective To investigate the characteristics of common deafness genes mutation from 222 sensori-neural hearing loss patients in Guangxi province.Methods A deafness-related gene mutations detection kit was used to detect 15 mutation sites in four deafness-associated genes.A total of 222 hearing impaired patients,who were selected from January 2015 to April 2016,were tested.The samples that could not be diagnosed with DNA mi-croarray were subjected to PCR and sequenced to detect other mutations.Results Among the 222 patients with sen-sorineural deafness,the total mutation rate was 10.36% (23/222),including GJB2 235delC homozygous in 3 cases (1.35%),235delC single heterozygous mutation in 8 cases (3.60%),35delG single heterozygous mutation in 2 cases (0.90%),GJB2 235delC and 109 A>G mutations in 2 cases (0.90%),SLC26A4 1229C>T homozygous in 2 case (0.90%),IVS7-2 A>G heterozygous mutation in 2 cases (0.90%);IVS7-2A>G,IVS11+47T>C and 1548 insC mutations in 2 cases (0.90%);GJB3 538C>T heterozygous mutation in 1 cases (0.45%);Mitochondrial 12S rRNA gene heterogeneous mutations in 1 case (0.45%).One of them carry both two mutations:GJB2 235 del C and SLC26A4 1226 G>A.Conclusion The results indicate that GJB2 and SLC26A4 were the main genes in this study,and in Guangxi province the mutation rate is significantly lower than the national average level.3 new muta-tions (SLC26A4 IVS11+47T ! C,1548insC and GJB2 109A>G)were found.There may be some rare mutations among sites or genes caused deafness in Guangxi.
