Objective:To study the effect of laparoscopic transabdominal preperitoneal (TAPP) and mesh plug repair on the sexual function of patients with indirect inguinal hernia.Methods:One hundred and four patients with indirect inguinal hernia who were treated in the No.922 Hospital of PLA Joint Logistics Support Force from January 2018 to October 2019 were selected and divided into two groups according to the method of random number table: routine group and TAPP group, with 52 cases in each group. The routine group was treated with mesh plug repair, and the TAPP group was treated with TAPP. The international erectile function index-5 (IIEF-5) was used to evaluate the sexual function of the patients after operation for 6 months, the visual analog pain scale (VAS) was used to evaluate the pain after operation for 1 month, and the relevant indexes of the operation and the incidence of complications were compared.Results:The IIEF-5 scores at 6 months after operation in two groups was higher than that before operation, the testicular volume and the maximum blood flow velocity of testicular artery in two groups were lower than those before operation, and the differences were statistically significant ( P<0.05); the IIEF-5 scores at 6 months after operation in the TAPP group was higher than that in the routine group [(23.86 ± 1.5) scores vs. (21.45 ± 3.85) scores], and the testicular volume and the maximum blood flow velocity of testicular artery were higher than those in the routine group [(9.65 ± 0.08) cm 3 vs. (9.39 ± 0.09) cm 3, (3.83 ± 1.05) cm/s vs. (2.88 ± 0.36) cm/s], and the differences were statistically significant ( P<0.05). One month after operation, the pain scores of two group were lower than that before operation, and the pain scores of TAPP group was lower than that of routine group [(1.65 ± 0.35) scores vs. (2.78 ± 0.39) scores], and the differences were statistically significant ( P<0.05). The operation time of TAPP group was higher than that of routine group [(44.35 ± 6.26) min vs. (41.80 ± 5.95) min], the bleeding volume, the time of getting out of bed, the time of hospitalization of TAPP group were lower than those of routine group [(54.66 ± 8.98) ml vs. (73.25 ± 15.25) ml, [(12.75 ± 2.42) h vs. (23.55 ± 3.66) h], (3.25 ± 1.01) d vs. (7.85 ± 1.44) d], and the differences were statistically significant ( P<0.05). The incidence of operation complications of TAPP group was lower than that of routine group [3.85%(2/52) vs. 21.15%(11/52)], and the difference was statistically significant ( χ2=7.121, P<0.05). Conclusions:Compared with conventional hernia repair, laparoscopic hernia repair can improve the sexual function, relieve the pain, improve the therapeutic effect and reduce the complications.

[Objective] To analyze the influencing factors of repeat blood donor lapsing using a zero-inflated poisson regression model (ZIP). [Methods] The blood donation behavior of 12 498 whole blood donors from 2020 was tracked until December 31, 2023. The factors influencing the frequency of blood donations in a given year was analyzed using ZIP, and donors with 0 blood donation in that year were considered to have lapsed. The changes in relevant influencing factors associated with each blood donation were measured and modeled for analysis. [Results] The zero-inflated part of ZIP showed that the risk of lapsing of male blood donors was 2.24 times that of female blood donors (OR 95% CI:1.864-2.696, P<0.001); the risk of lapsing of the 35-44 age group and over 45 age group was respectively 40% (OR 95% CI:0.455-0.790, P<0.001) and 61%(OR 95% CI:0.268-0.578, P<0.001) lower than that of the under 25 age group; the risk of lapsing for those who have donated blood twice and ≥3 times was respectively 50% (OR 95% CI:0.405-0.609, P<0.001) and 81% (OR 95% CI:0.154-0.225, P<0.001) lower than that of first-time donors; the risk of lapsing of those with junior high or high school education was 1.2 times that of those with a college degree or higher (OR 95% CI:1.033-1.384, P<0.05); the risk of lapsing for the divorced group was 2.02 times that of the married group (OR 95% CI:1.445-2.820, P<0.001); the risk of lapsing for those with an income (Yuan) of 10 000 to 50 000, 50 000 to 100 000 and more than 100 000 was respectively 0.67 (OR 95% CI:0.552-0.818, P<0.001), 0.72 (OR 95% CI:0.591-0.884, P=0.002) and 0.67 (OR 95% CI:0.535-0.834, P<0.001) times that of those with an income (Yuan) of less than 10 000. The results of the Poisson part are consistent with the results of the zero-inflated part in terms of age and education level. [Conclusion] Blood donor lapsing is overall related to factors such as gender, age, donation frequency, education, marital status and family income. It's essential to care for those blood donors prone to lapse to retain more regular blood donors.
