Background Platelet parameters are important indicators of cardiovascular risk, and environmental pollutants such as polychlorinated biphenyls (PCBs) may impair platelet function through oxidative stress. Objective To investigate the differential effects of single and mixed exposure to PCBs on platelet parameters among individuals with normal glucose tolerance (NGT), impaired fasting glucose (IFG), and type 2 diabetes mellitus (T2DM), and to evaluate the potential modifying role of a healthy lifestyle. Methods This study included 2249 participants (including 707 with NGT, 759 with IFG, and 783 with T2DM). Plasma PCB concentrations were measured using triple quadrupole gaschromatography-tandem mass spectrometry. Generalized linear regression was used to assess the associations between individual PCB congeners and platelet parameters. Quantile g-computation (QGC) and Bayesian kernel machine regression (BKMR) models were used to evaluate the overall effects of PCBs mixture exposure on platelet parameters across different glycemic states, as well as its interaction with healthy lifestyle score (HLS). Results Generalized linear regression analyses showed significant differences in the effects of PCBs on platelet parameters across different glycemic states (P<0.05). After adjusting for confounders, PCBs mixture exposure was significantly associated with lower platelet counts (PLT) in individuals with NGT (b=−10.60, 95%CI: −16.48, −4.71) and IFG (b=−12.91, 95%CI: −18.90, −6.92), whereas no significant association was observed in individuals with T2DM (P=0.051). Mean platelet volume (MPV) and platelet-large cell ratio (P-LCR) increased significantly with higher PCBs exposure levels across all three groups (P<0.05). BKMR analysis showed a positive association between PCBs mixture exposure and P-LCR, with the strongest association observed in the NGT group. Furthermore, a significant interaction was observed between HLS and PCBs mixture exposure, and a higher HLS attenuated the effects of PCBs on P-LCR. Conclusion Glycemic glycemic states may modify the effects of PCBs on platelets. Individuals with NGT appear more sensitive to PCBs exposure, whereas the T2DM state may attenuate this effect. Moreover, healthy lifestyles, including not smoking, moderate alcohol consumption, maintaining moderate-to-high physical activity, a healthy diet, and an appropriate body mass index (BMI), may mitigate the adverse effects of most PCBs on platelet parameters.

To clarify the genetic diversity and structure of the nucleus population of F1-generation Litopenaeus vannamei, this study utilized 15 pairs of highly polymorphic microsatellite primers to analyze the simple sequence repeat (SSR) markers and genetic diversity in 15 full-sib families of L. vannamei. A total of 112 alleles (N_a) and 60.453 effective alleles (N_e) were identified among the selected 15 SSR loci, with the average polymorphic information content (PIC) of 0.648. The average N_e, observed heterozygosity (H_o), and expected heterozygosity (H_e) in the 15 F1 families varied from 1.925 to 2.626, 0.425 to 0.783, and 0.403 to 0.572, respectively. The 15 full-sib families were primarily clustered into three categories in the phylogenetic analysis, with the genetic distance between families ranging from 0.252 to 0.574. Additionally, the genetic differentiation coefficient (F_st) among the families varied from 0.112 to 0.278, indicating substantial genetic differentiation. Overall, this study suggested that the genetic diversity of the 15 full-sib families was moderate, providing valuable genetic insights for the subsequent breeding initiatives aimed at enhancing the tolerance of L. vannamei to high levels of soybean meal.

Biomaterials have gained substantial attention in the field of regenerative medicine and shown respectable potential in clinical translation. However, the function of biomaterials is hindered by the fibrotic encapsulation of foreign body response (FBR) under some circumstances. FBR also lowers the expected service life of implanted devices and causes pain, distortion of tissue or even malignant diseases. Therefore, the mechanism of FBR and the modulating factors need to be further investigated to improve the tissue biocompatibility of biomaterials. This article reviewed the process of FBR, summarized the properties and modification of biomaterials related to FBR, and discussed strategies to mitigate this immune reaction.

[Objective] To investigate the clinical manifestations and explore the experience of diagnosis and treatment of spontaneous perirenal urine extravasation after urinary tract obstruction so as to improve the understanding of the disease. [Methods] The clinical data of 23 patients with spontaneous perirenal urine extravasation after obstruction treated at our hospital during 2018 and 2020 were retrospectively analyzed, including the primary diseases, clinical manifestations, imaging examination, treatment and prognosis. The key points of diagnosis and treatment were summarized. [Results] Of the 23 patients, there were 15 males and 8 females, with an average age of 43.4 years. These cases were diagnosed by imaging tests such as ultrasound, computed tomography urography (CTU) and CT. Ureteroscopic lithotripsy was performed in 3 patients with ureteral calculi, retrograde ureteral catheterization in 4 patients and percutaneous nephrostomy in 13 patients. Afterwards, a second phase surgery was performed based on the patients' condition. Of the 3 patients with tumor metastasis who underwent retrograde ureteral catheterization, 2 operation were successful, and 1 operation failed and then converted to nephrostomy and drainage under B-ultrasound localization. [Conclusion] CTU should be performed as soon as possible to make a definite diagnosis. Treatment can be achieved with ureteral retrograde catheterization or percutaneous nephrostomy to achieve local decompression, followed by secondary surgery to treat the primary cause of obstruction.

Objective To investigate the role of cardiac rehabilitation program in the early recovery after minimally invasive incision coronary artery bypass grafting with general anesthesia. Methods A retrospective study was performed on the patients who underwent minimally invasive incision coronary artery bypass grafting from January 2015 to January 2020 with general anesthesia in our hospital. The patients were divided into a cardiac rehabilitation group and a control group. The clinical data of the patients were collected in 6 months and 12 months after the beginning of cardiac rehabilitation program and were analyzed by propensity score-matching analysis with a ratio of 1∶1. The main outcomes were the peak oxygen uptake (VO2 peak) of cardiopulmonary function test and the number of patients attending cardiovascular specialties in tertiary hospitals during the follow-up period (20 months). Results A total of 600 patients were enrolled, including 200 patients in the cardiac rehabilitation group [137 males and 63 females, aged 61.00 (56.00, 65.00) years] and 400 patients in the control group [285 males and 115 females, aged 60.00 (56.00, 65.00) years]. After matching, 176 patients were included in each group, and the basical clinical data of the pateints were comparable (P>0.05). The VO2 peak of the cardiac rehabilitation group after 6 months and 12 months of cardiac rehabilitation was significantly different from that of the control group [6 months: 1.96 (1.59, 2.38) L/min vs. 1.72 (1.38, 2.12) L/min, P<0.001; 12 months: 2.40 (2.21, 2.63) L/min vs. 2.12 (1.83, 2.45) L/min, P<0.001]. During the follow-up period, there was a statistical difference in the cardiovascular specialist visits in tertiary hospitals (P=0.004). Conclusion Cardiac rehabilitation program has a positive effect on the recovery of minimally invasive incision coronary artery bypass grafting with general anesthesia, and can improve the exercise ability of patients.
