Objective To compare the clinical efficacy and safety of early endovascular treatment(EVT)for the stroke patients caused by large vessel occlusion(LVO)due to intracranial atherosclerosis(ICAS)or due to cardioembolism(CE).Methods The clinical data of 488 patients with acute anterior circulation LVO stroke,who received early endovascular treatment at the Yijishan Hospital of Wannan Medical College of China from October 2015 to December 2023,were retrospectively analyzed.According to the cause of disease,the patients were divided into ICAS group(n=108)and CE group(n=380).The clinical data,mainly including the proportion of patients having a good prognosis at 90 days after operation(modified Rankin Scale score ≤2 points),the incidence of symptomatic intracranial cerebral hemorrhage(sICH),and the mortality of patients at 90 days after operation.Multivariate logistic regression analysis was used to analyze the factors influencing patient's prognosis.Results Of the 488 patients,29(5.9％)developed postoperative sICH,242(49.6％)achieved a good prognosis at 90 days after the operation,and 91(18.6％)died.The above outcomes in the ICAS group were one,66,and 11 patients respectively,which in the CE group were 28,176,and 80 respectively,and the differences between the two groups were statistically significant(all P＜0.05).Multivariate logistic regression analysis indicated that good prognosis at 90 days after the operation(OR=0.962,95％CI:0.404-2.288,P=0.930)and the postoperative 90-day mortality(OR=1.379,95％CI:0.436-4.362,P=0.584)were not the factors influencing prognosis,while the postoperative sICH(OR=19.132,95％CI:1.332-274.791,P=0.030)was the factor influencing prognosis.Conclusion In CE group,the incidence of sICH and the postoperative 90-day mortality are higher,while in ICAS group,the postoperative 90-day good prognosis rate is higher.The postoperative sICH is the factor influencing prognosis.

Objective:To explore the independent risk factors for the occurrence and aggravation of lower back pain (LBP) in patients with Parkinson′s disease (PD), in order to provide reference for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the case data of 309 PD patients who visited the Affiliated Yixing Hospital of Jiangsu University from June 2018 to May 2020. The KING Parkinson′s Disease Pain Scale (KPPS) was used to quantitatively evaluate the LBP of PD patients, who were divided into LBP group and Non LBP group. The general clinical data, PD related data, and imaging data of the two groups were compared and analyzed. Binary logistic regression analysis was used to evaluate independent risk factors for LBP in PD patients. Pearson correlation analysis was conducted between KPPS scores and various factors, and linear regression analysis was used to identify the relevant risk factors that exacerbate LBP in PD patients.Results:Compared with the Non LBP group, the LBP group had lower bone mineral density (BMD) and a lower proportion of patients who engaged in daily exercise. The difference between the two groups was statistically significant (all P<0.05). Compared with the Non LBP group, patients in the LBP group had a longer course of illness, higher stiffness scores, a higher proportion of patients with fluctuating symptoms, higher UPDRS-Ⅲ scores, and a higher proportion of patients with thoracolumbar fascial injury (TLFI) and lumbar sagittal imbalance. The differences between the two groups were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that combined TLFI ( OR=2.773, 95% CI: 1.219-6.309, P=0.015), combined lumbar sagittal imbalance ( OR=4.835, 95% CI: 2.244-10.421, P<0.001), and lower BMD ( OR=2.818, 95% CI: 1.767-4.493, P<0.001) were risk factors for LBP in PD patients. The KPPS score was correlated with BMD and TLFI ( r=-0.146, 0.294, all P<0.05). The linear regression results showed that the merged TLFI ( B=2.271, β=0.285, P<0.001) was positively correlated with KPPS score, indicating a risk factor. Conclusions:The combination of TLFI, lumbar sagittal imbalance, and lower BMD is closely related to the occurrence of LBP in PD patients, and the combination of TLFI is an independent risk factor for exacerbating LBP symptoms. Clinical attention should be paid to the prevention and treatment of TLFI in PD patients.

Single-cell or low-input multi-omics techniques have revolutionized the study of pre-implantation embryo development.However,the single-cell or low-input proteomic research in this field is rela-tively underdeveloped because of the higher threshold of the starting material for mammalian embryo samples and the lack of hypersensitive proteome technology.In this study,a comprehensive solution of ultrasensitive proteome technology(CS-UPT)was developed for single-cell or low-input mouse oocyte/embryo samples.The deep coverage and high-throughput routes significantly reduced the starting material and were selected by investigators based on their demands.Using the deep coverage route,we provided the first large-scale snapshot of the very early stage of mouse maternal-to-zygotic transition,including almost 5,500 protein groups from 20 mouse oocytes or zygotes for each sample.Moreover,significant protein regulatory networks centered on transcription factors and kinases between the MII oocyte and 1-cell embryo provided rich insights into minor zygotic genome activation.

Objective: To establish experimental porcine model of reconstruction the neobladder by ileal seromuscular with transplantation of autologous peritoneum. Methods: This was an animal experiment carried out from January to April 2018 at animal center of Guizhou Medical University. Randomly 6 experimental female porcines were chosen, and their body weight was 28 to 33 kg. By intravenous anesthesia, the transplantation of autologous peritoneum for bladder reconstruction operation was carried out by transplanting the peritoneum onto an ileum segment which mucosa and submucosa had been removed. These flaps were used to mend and reconstruct the neobladder by suturing with edge of the detective bladder. After removal of ureteral catheters and balloon catheter at day 5 and day 7 respectively, voiding behavior was monitored, and animals were euthanized at week 12 for routine pathology, immunohistochemistry, and electron microscopic examinations. Results: Six porcines underwent reconstruction, but no one lost to complications such as peritonitis, ileus and urinary fistula. Voiding behavior was normal, and urine was clear in all animals after removal of catheters. At autopsy, reconstructed bladders were healthy. Pathological examination showed the part of reconstruction had been covered by continuous urothelium while the peritoneum disappeared and showed no ileal mucosa regrowth and residual. Scanning electron microscope showed that the transitional cells of neobladder were complete and orderly, and urothelium around suture border was continuous and no malposition. Conclusion In this experimental porcine model, reconstruction bladder by autologous peritoneum and ileal seromuscular flaps is an ideal approach.
