Objective To investigate the potential beneficial predictors for endovascular treatment(EVT)in case of acute anterior circulation large vessel occlusion with large-core infarction.Methods We made a retrospective inclusion of 92 patients with anterior circulation large vessel occlusion and core infarct volume ranging from 50 to 100 mL,who underwent EVT at Zhangzhou Municipal Hospital of Fujian Province from March 2018 to February 2021.All the patients were confirmed as anterior circulation large infarction and large infarct volume using computed tomography(CT),computed tomography angiography(CTA),and computed tomography perfusion(CTP)before EVT.All clinical and imaging data were collected to observe the postoperative recurrence rate,incidence of symptomatic intracranial hemorrhage(sICH),and functional prognosis 90 days.Then the patients were divided into favorable outcomes group(mRS≤3)and unfavorable outcomes group(mRS>3)based on Rankin scores 90 days post-stroke.Univariate and multivariate Logistic analysis were conducted to analyze factors influencing the patients'prognosis.By combining the results of multivariate analysis,we constructed receiver operating characteristic(ROC)curves and identified the cut-off value to evaluate the predictive value of age for post-vascular treatment prognosis.Results Among the included patients,the postoperative revascularization rate(mTIICI≥2b)was 95%(88 cases),the rate of favorable outcomes at 90 days postoperatively(mRS≤3)was 32.61%(30 cases),the incidence of sICH was 13%,and the mortality rate was 31.5%.Compared with the unfavorable outcomes group,the favorable outcomes group had a younger age and a higher proportion of males.Multivariate analysis indicated that older age was an independent risk factor for adverse outcomes following endovascular treatment(OR=4.97,95%CI:1.78-13.90,P=0.002).The ROC curve indicated that the area under the curve was maximized at the age of 72.5 years(AUC=0.763,95%CI:0.661-0.864,P<0.001).Its sensitivity and specificity was 0.565 and 0.833,respectively.Conclusion Age is an independent predictor of the prognosis of acute procirculatory large core stroke.Patients with large core infarction older than 72.5 years may not benefit from endovascular therapy,which needs to be confirmed by a multicenter large sample prospective randomized controlled trial.

Cathepsin D (CTSD), the major lysosomal aspartic protease that is widely expressed in different tissues, potentially regulates the biological behaviors of various cells. Follicular granulosa cells are responsive to the increase of ovulation number, hence indirectly influencing litter size. However, the mechanism underlying the effect of CTSD on the behaviors of goat granulosa cells has not been fully elucidated. This study used immunohistochemistry to analyze CTSD localization in goat ovarian tissues. Moreover, western blotting was applied to examine the differential expression of CTSD in the ovarian tissues of monotocous and polytocous goats. Subsequently, the effects of CTSD knockdown on cell proliferation, apoptosis, cell cycle, and the expression of candidate genes of the prolific traits, including bone morphogenetic protein receptor IB (

Objective:After general anesthesia and mechanical ventilation for laparoscopic colorectal cancer resection, about 90% of patients would have different degrees of atelectasis. Authors speculated that an open-lung strategy (OLS) comprising moderate positive end-expiratory pressure (PEEP) and intermittent recruitment maneuvers (RM) can reduce atelectrauma and thus reduce the incidence of oxygenation-impairment during low-tidal-volume ventilation for laparoscopic colorectal cancer resection. The purpose of this study was to verify this hypothesis and provide a better intraoperative ventilation scheme for laparoscopic colorectal cancer resection.Methods:This was a prospectively randomized controlled clinical trial which was approved by the Ethics Committee of the Sixth Affiliated Hospital, Sun Yat-sen University (2017ZSLYEC-002), and registered at the ClinicalTrials.gov (NCT03160144). From January to July 2017, patients who underwent laparoscopic colorectal cancer resection, with age > 40 years, estimated pneumoperitoneum time ≥ 1.5 h, pulse oxygen saturation ≥ 92%, and risk grade for postoperative pulmonary complications ≥ 2 were prospectively enrolled. The patients with American Society of Anesthesiologists physical status ≥ IV, body mass index ≥ 30 kg/m 2, pneumonia, acute respiratory failure or sepsis within 1 month, severe chronic obstructive pulmonary disease, pulmonary bullae and progressive neuromuscular diseases, and those participating in other interventional clinical trials were excluded. The enrolled patients were randomly assigned (1:1) to the OLS group (with a PEEP of 6-8 cm H 2O and intermittent RM), and the NOLS group (without using PEEP and RM). Partial pressure of arterial oxygen (PaO 2) /fraction of inspired oxygen (FiO 2) and shunt fraction (Q S/Q T) were calculated via arterial and central venous blood gas analysis performed at 0.5 h (T 1), 1.5 h (T 2) after pneumoperitoneum induction and at 20 min after admission to the recovery room. Driving pressure immediately before pneumoperitoneum induction (T 0) and at T 2 were calculated via monitoring data. The primary outcome was oxygenation-impairment (PaO 2/FiO 2 ≤ 300 mmHg) during mechanical ventilation. Results:In each group, 48 patients under general anesthesia and low-tidal-volume ventilation were included in the final analysis. During ventilation, the oxygenation-impairment occurred in 7 patients (14.6%) of OLS group and in 17 patients (35.4%) of NOLS group, whose difference was statistically significant between two groups (χ 2=5.556, RR=0.31, 95%CI: 0.12 to 0.84, P=0.033). During ventilation, the patients in the OLS group had higher PaO 2/FiO 2 [T 1: (427±103) mmHg vs. (366±109) mmHg, t=-2.826, P=0.006; T 2: (453±103) mmHg vs. (388±122) mmHg, t=-2.739, P=0.007], lower Q S/Q T [ T 1: (9.2±6.5) % vs. (12.6±7.7) %, t=2.322, P=0.022; T 2: (7.0±5.8)% vs.(10.9±9.2)%, t=2.408, P=0.019], and lower driving pressure [T 0: (6±3) cm H 2O vs. (10±2) cm H 2O, t=7.421, P<0.001; T 2: (13±3) cm H 2O vs. (17±4) cm H 2O, t=5.417, P<0.001] than those in the NOLS group, with stratistical differences in all comparisons. In recovery room, though PaO 2/FiO 2 [(70.3±9.4) mmHg vs. (66.8±9.4) mmHg, P=0.082] was still higher and Q S/Q T [(18.6±8.3)% vs. (21.8±8.4)%, P=0.070] was still lower in the OLS group as compared to the NOLS group, the differences were not statistically significant (both P>0.05). Conclusion:The application of such an OLS during low-tidal-volume ventilation can greatly reduce the incidence of oxygenation-impairment in laparoscopic colorectal cancer resection, and such effect may last to the period of emergence from anesthesia.

Objective To examine the current situation of the career plateau among anesthesiologists and analyze the impact of occupational stressors on it. Methods A questionnaire survey was conducted on the anesthesiologists. A total of 300 questionnaires were distributed and 278 questionnaires were effectively collected. Statistical analysis using SPSS 19.0 was performed to assess the status quo of career plateau among anesthesiologists. Pearson correlation analysis and stepwise regression analysis were used to analyze the influence of occupational stressors on career plateau . Results The average value of occupational stressors among anesthesiologists was (3.22±0.55), and the average value of career plateau was (3.90±0.70). Occupational interest in the occupational stressors of anesthesiologists is negatively correlated with the occupational plateau (r=-0.552, P<0.01), and career development is negatively correlated with occupational plateau (r=-0.541, P<0.01) as well. Both occupational interest and career development show a negative predictive effect on the career plateau (β=-0.359, P<0.01 andβ=-0.334, P<0.01, respectively). Conclusion Career plateau among anesthesiologists is at a medium-to-high level. Occupational interest and occupational development in occupational stressors have a negative predictive effect on occupational plateaus, so hospital managers should pay attention to them.
