Objective To investigate the effects of infrasound at different frequencies on the pathological morphology of mouse testes and to explore the possible involvement of β-cateinin in the mechanism of injury. MethodsSixty adult BALB/C mice were randomly divided into 2 groups.One group of 6 mice were the controls without infrasound exposure.The other group with 54 mice was evenly divided into 3 subgroups of 18 exposed to 130 dB infrasound at 4 Hz,8 Hz or 20 Hz for 2 hours daily.The pathological morphology of the mice's testes was observed 3,9 and 21 h after exposure.Immunohistochemical staining was used to examine β-catenin expression 3 h after exposure.ResultsMarked damage was observed in the morphology of the testicular cells of rats in the 8 Hz group.Cell denaturation was found in germinal cells.The cell structure was loosened and the cell junctions had decreased or disappeared.The damage was most serious at 3 h after exposure.But at the same time point,pathological damage of testicular cells was not obvious in the 4 Hz group,with only a few testes cells swollen.The morphology of testicular tissue of mice in the 20 Hz subgroup exhibited no significant difference from the control group.β-catenin was mainly found in the membranes of Leydig cells,Sertoli cells and myoepithelial cells in all of the mice,and there was no significant change in the expression level or distribution pattern between the exposed mice and the controls.No expression ofβ-catenin was found in spermatogenic cells. ConclusionInfrasound at 4 Hz or 8 Hz can damage testicular tissue,at least in mice.At 20 Hz there is no significant effect on the testes.The loosened cell structure might have been caused by the mechanical force produced by the infrasound and not by any decrease of β-catenin.

Objective:To investigate the clinical characteristics and related risk factors of sarcopenia in elderly patients undergoing maintenance hemodialysis.Methods:This was a retrospectively study involving 135 elderly hemodialysis patients aged(70.6±7.7)years, with 46(34.1%)females and a mean hemodialysis duration of(3.2±2.9)years, at Shanghai Sixth People's Hospital.The incidence of sarcopenia in patients was examined by measuring handgrip strength, walking speed and muscle mass of the limbs using bioelectrical impedance analysis.Related risk factors were analyzed with univariate and multivariate logistic regression analysis.Results:Among 135 elderly hemodialysis patients, the incidence of sarcopenia was 62.9%(85 cases), and severe sarcopenia cases accounted for 44.4%(60 cases). Compared with the non-sarcopenia group, patients with sarcopenia were older, had lower body mass index(BMI)and handgrip strength, walked more slowly and had less muscle mass in their limbs.Advanced age, low BMI and long dialysis duration were correlated with the high incidence of sarcopenia in elderly dialysis patients.The odds ratio( OR)for sarcopenia increased by 12% per year, and the OR decreased by 32% with an increase of 1.0 kg/m 2 in BMI.Advanced age and lower BMI were also correlated with a high incidence of severe sarcopenia( OR=1.12, 95% CI: 1.05~1.18; OR=0.84, 95% CI: 0.74~0.95; all P<0.01). Conclusions:The incidence of sarcopenia is high in elderly hemodialysis patients and is closely related to advanced age and low body weight.Improving nutritional status and avoiding low body weight will help reduce the occurrence and development of sarcopenia in elderly hemodialysis patients.

Objective:To evaluate the effects of different doses of sivelestat sodium on perioperative acute lung injury (ALI) in the patients undergoing emergency surgery for acute Stanford type A aortic dissection (AAAD).Methods:A total of 120 patients of both sexes, aged 30-64 yr, with body mass index of 18.5-24.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ, scheduled for emergency AAAD surgery, were divided into 3 groups using a random number table method: low-dose sivelestat sodium group (SL group), medium-dose sivelestat sodium group (SM group)and high-dose sivelestat sodium group (SH group), with 40 patients in each group. Sivelestat sodium 4.8, 6.0 and 7.2 mg/kg were intravenously infused starting from 10 min before anesthesia until 24 h after surgery in SL, SM and SH groups, respectively. Blood samples from the radial artery were collected for blood gas analysis after anesthesia induction and before skin incision (T 1), immediately after the end of surgery (T 2), at 24 h after surgery (T 3), and 72 h after surgery (T 4), the alveolar-arterial oxygen tension difference (PA-aDO 2), oxygenation index (OI)and respiratory index (RI) were calculated. The duration of postoperative mechanical ventilation, length of stay in the intensive care unit (ICU) and length of postoperative hospital stay were recorded. Central venous blood samples were collected at T 1-T 4 to measure serum concentrations of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6)and IL-8. Peripheral venous blood samples were collected on preoperative day 1 and postoperative days 1 and 3 to measure white blood cell (WBC) count, neutrophil (NEUT) count, neutrophil percentage (NEUT%), and C-reactive protein (CRP) concentration. The occurrence of postoperative pulmonary complications (PPCs)and 90-day all-cause mortality were recorded. Results:Compared with the baseline at T 1, PA-aDO 2 and RI were significantly increased, OI was decreased, and the serum concentrations of TNF-α, IL-6 and IL-8 were increased at T 2-T 4 in all the three groups ( P<0.05). WBC, NEUT, NEUT% and concentrations of CRP were significantly higher on postoperative days 1 and 3 than on 1 day before surgery in the three groups ( P<0.05). Compared with SL and SM groups, PA-aDO 2 and RI were significantly decreased, OI was increased, and the serum concentrations of TNF-α, IL-6 and IL-8 were decreased, the WBC count, NEUT count, NEUT% and concentrations of CRP were decreased, the incidence of postoperative hypercapnia, hypoxemia, emerging lung rales and bronchospasm was decreased, and the duration of postoperative mechanical ventilation and length of intensive care unit stay were shortened( P<0.05), and no significant change was found in the postoperative length of hospital stay and 90-day all-cause mortality rate in SH group ( P>0.05). Conclusions:Sivelestat sodium 7.2 mg/kg can significantly inhibit the inflammatory responses, alleviate perioperative ALI, and improve early prognosis in the patients undergoing AAAD surgery.
