Objective. To explore the effect of laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) combined with biological mesh on the reproductive function of male inguinal hernia patients during the reproductive period. Methods. Sixty male inguinal hernia patients during the reproductive period admitted to our department from October 2015 to October 2021 were selected for retrospective analysis. All patients were treated with TAPP combined with biological mesh by the same team. Bilateral testicular volume, testicular temperature, testicular blood perfusion, peripheral serum testosterone concentration, and semen analysis were examined before surgery, 3 months after surgery, 6 months after surgery, and 12 months after surgery. Results. The preoperative testicular volume, temperature, and blood perfusion were compared between the healthy side and the affected side; the testicular volume, temperature, blood perfusion of the affected side, peripheral blood testosterone concentration, and semen analysis were compared among the four time points, which were before operation, 3 months after operation, 6 months after operation, and 12 months after operation. All p values were >0.05. Conclusions. The presence of inguinal hernia had no significant effect on the volume and blood perfusion of male testis. In addition, TAPP combined with biological mesh has no negative effect on postoperative reproductive function of male inguinal hernia patients of childbearing age, which manifested as a safe and feasible surgical method.

Rechargeable batteries based on solid-state electrolytes are of great interest and importance for the next-generation energy storage due to their high energy output and improved safety. For building the solid-state batteries, Na3Zr2Si2PO12 (NZSP) represents a promising candidate as it features high chemical stability against air exposure and a high Na+ conductivity. NZSP pellets were usually calcined at a high temperature, and the high volatility of Na and P elements easily led to the formation of impurity phase. In this work, the effects of calcination temperature and stoichiometry on the phase purity and ionic conductivity of the NZSP electrolyte were studied. At an elevated sintering temperature, the NZSP electrolyte showed a high ionic conductivity owing to decreased porosity, and the highest ionic conductivity at 30 °C was observed to be 2.75 × 10–5 S·cm−1 with an activation energy of 0.41 eV. For the stoichiometry, the introduction of 5 mol% excessive P results in formation of more Na3PO4 and glass-like phase at the grain boundary, which caused the blurred grain boundary and reduced grain barrier, and effectively suppressed Na dendrite growth, then accounted for improved cycling performance of a Na||Na symmetric cell. Our work provided insights on reasonable design and preparation of NZSP electrolyte towards practical realization of solid-state Na-metal batteries. 摘要: 基于固态电解质的可充电电池表现出高的能量密度和高安全性, 具有重要的研究意义。其中, Na3Zr2Si2PO12(NZSP)具有高离子电导率以及高的空气稳定性, 是一类很有前景的固态电解质。NZSP通常需要高温焙烧, 但是高的焙烧温度易导致Na, P等元素的挥发, 从而导致杂相的形成。在本工作中, 我们研究了焙烧温度以及化学计量比对NZSP相结构以及离子电导率的影响。随着焙烧温度升高, NZSP电解质孔隙率降低, 电导率升高, 30 °C时最高的离子电导率为2.75 × 10–5 S·cm−1, 活化能0.41 eV。同时, 当引入5 mol%过量的P时, 产生更多的Na3PO4, 并在晶界处形成玻璃态, 从而有效抑制钠枝晶, 提高Na||Na对称电池的循环稳定性。我们的工作为NZSP电解质的设计与制备提供了新见解。 [ABSTRACT FROM AUTHOR]

As the changing of the face pose, the rate of the face recognition becomes small. Object to the problem, the method which based on affine transformation and image-forming principle corrected the test face images pose to virtual the corresponding font face images. The method could correct the multi-pose face images which angle were among 45°. And the face recognition based on improved SURF (speeded up robust features) got better effect. The experiment shows that the method overcomes the effect of the pose-changing to some degree and the recognition rate is increased by 7. 0%. [ABSTRACT FROM AUTHOR]

Rationale: Diffuse intestinal and mesenteric lipomatosis is a rare condition characterized by the overgrowth of adipose tissue in the intestines and mesentery. This case report aims to highlight the rare occurrence of chronic abdominal distention caused by this disease and its unique invasion into the muscle layer, which has not been previously reported., Patient Concerns: A 36-year-old woman with a 7-year history of abdominal distension was admitted to our hospital's Department of Gastrointestinal Surgery., Diagnose: Abdominal and pelvic computed tomography revealed diffuse small intestinal lipomatosis., Interventions: The patient underwent surgery. We performed an open-field ilectomy involving removal of all lipomatous intestines (250 cm)., Outcomes: During the surgery, diffuse nodular ileal and mesenteric lipomatosis was confirmed, characterized by the presence of multiple nodular lipomas within the submucosal and muscular layers. The surgical intervention involved the resection of 250 cm of the affected ileum, followed by jejunoileal anastomosis. Postoperative pathology confirmed the diagnosis, with lesions observed in both the submucosa and muscle layers. The patient showed significant improvement in symptoms, with normal intestinal function and weight gain observed over a 10-month follow-up period, and no signs of recurrence., Lessons: Diffuse intestinal and mesenteric lipomatosis can lead to long-term abdominal distension. Additionally, it may be involved in the muscle layer of the intestinal wall. Surgery is the primary treatment option for symptomatic intestinal lipomatosis., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Toxic effects of tributyltin (TBT) on the growth, peak diameter and photosynthetic activity (F(v)/F(m)) of fifteen predominant phytoplankton species in China coastal sea of Leptocylindru danicus, Skeletonema marinoi, Asterionella japonica, Bacilaria paxillifera, Chaetoceros debilis, Chaetoceros socialis, Thalassiosira, Amphidinium carterae, Karenia mikimotoi, Prorocentrum minimum, Gymnodinium sp., Scrippsiella trochoidea, Gymnodinium simplex, Prorocentrum triestinum and Heterosigma akashiwo were systematically studied. 96 h-EC50 of TBT were 136.42, 3.55, 3.15, 2.95, 1.90, 1.08, 0.70, 21.60, 7.71, 4.77, 3.81, 2.04, 0.53, 0.51, 1.76 microg/L, respectively. The no detectation effect concentration were 112.62, 1.19, 1.17, 3.70, 0.95, 1.07, 0.80, 6.28, 1.84, 0.99, 3.73, 1.63, 0.23, 0.16, 1.76 microg/L, respectively. The results indicated that the toxic effects of TBT were very different among different phytoplankton species and the resistance of Leptocylindru danicus was stronger than those of other microalgae. The TBT not only inhibited the growth of phytoplankton, but also changed the peak diameter and decreased the photosynthetic activity (F(v)/F(m)). Besides that, we infer that there may have a relationship between the toxicity of TBT and the composition of predominant phytoplankton population in harbour.
