Objective To evaluate the influence of a selective Rho-associated protein kinase inhibitor (fasudil hydrochloride) on outflow facility in enucleated porcine,rabbit and bovine eyes.Methods At the constant perfusion pressure of 15 mm-Hg (1 kPa =7.5 mmHg),the baseline coefficient of outflow facility (C0) of the isolated porcine,rabbit and bovine eyes was recorded respectively.The enucleated porcine eyes were divided into two groups randomly (n =6),and they were control group and experimental group.The same grouping method was also used-C0 the ribbit and bovine eyes.The control group was subjected to GPBS perfusion,while the experimental group was treated with 100 μmol · L-1 fasudil solution,followed by recording the experimental coefficient of outflow facility (C1),as well as calculating ΔC (ΔC =C1-C0) and ΔC% (ΔC% =ΔC/C0).Finally,the paired t test and one-way analysis of variance were performed using SPSS 17.0.Results As for porcine eyes,the ΔC% of the control group was (17.83 ± 3.84) % while the experimental group was (44.00 ± 6.44) %;as for rabbit eyes,the ΔC% of the control group was (15.50 ± 2.93) %,while the experimental group was (31.67 ±6.54)%;as for bovine eyes,the ΔC% of the control group was (11.67 ± 1.17)%,while the experimental group was (37.17 ± 4.48)%.The ΔC% in the experimental group was significantly increased when compared with the control group in three animals,with significant difference (all P < 0.05).There was no statistical difference in ΔC% of three experimental groups among different kinds of animals (all P < 0.05).Conclusion Fasudil can improve outflow facility in enucleated eyes of animals,and it can redistribute aqueous humor drainage to a wider area through directly regulating the cytoskeleton of cells and matrix,resulting in increased coefficient of outflow facility.

Objective:To explore the occurrence time and risk factors of deep vein thrombosis (DVT) in patients with acute cerebral infarction, so as to guide clinical prevention and treatment.Methods:1 129 patients with acute cerebral infarction treated in Beijing Tiantan Hospital from May 2014 to May 2016 were selected as the research objects. According to whether DVT occurred, the patients were divided into DVT group ( n=22) and non DVT group ( n=1 107); The information was analyzed retrospectively and the occurrence time of DVT was counted. The independent risk factors of acute cerebral infarction complicated with DVT were analyzed by univariate and multivariate logistic regression. Results:The time of DVT in patients with acute cerebral infarction was 10.5 (4-14) days. Univariate analysis showed that there were significant differences in age, gender, atrial fibrillation, smoking, drinking, chronic obstructive pulmonary disease, peripheral artery disease, renal failure, anticoagulants, BMI, white blood cell, blood glucose at admission and length of stay between the DVT group and the non DVT group ( P<0.05). Multiple factors further confirmed that renal failure [odds ratio ( OR)=57.421; 95% confidence interval ( CI), 5.792-569.314)] and length of hospital stay ( OR=1.148; 95% CI: 1.071-1.232) were independent risk factors for DVT. Conclusions:The median time of DVT in patients with acute cerebral infarction was 10.5 days. Renal failure and hospital stay were independent influencing factors of DVT in patients with acute cerebral infarction. This is helpful to determine the best prevention and treatment duration of DVT in patients with acute cerebral infarction, make rational use of medical resources and formulate personalized prevention and treatment strategies.

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.

ObjectiveTo explore the mechanism of Renshen Baidusan in repairing intestinal mucosa in ulcerative colitis (UC) by regulating autophagy to scavenge peroxides. MethodThe mouse model of UC was induced by free drinking of 3.0% dextran sulphate sodium (DSS) solution. Sixty male C57BL/6J mice were randomized into normal, model, mesalazine (0.3 g·kg-1), and high-, medium-, and low-dose (12.35, 8.22, 4.11 g·kg-1, respectively) Renshen Baidusan groups (n=10). The mice were administrated with corresponding drugs by gavage for 7 consecutive days. The colon tissue was stained with hematoxylin-eosin (HE) to reveal the pathological changes, and Alcian blue-Periodic acid Scheff (PAS/AB) staining was employed to observe the goblet cell changes. The fluorescence expression of reactive oxygen species (ROS) in the colon tissue was detected by the immunofluorescence assay. The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) were measured by the biochemical methods. Western blot was employed to determine the expression levels of proliferating cell nuclear antigen (PCNA), microtubule-associated protein 1 light chain 3 (LC3), leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), and p62. ResultDestroyed mucosal epithelial structure, intestinal gland destruction, loss of goblet cells, and massive infiltration of inflammatory cells appeared in the model group. Compared with the normal group, the model group showed increased tissue damage injury (TDI) score of the colon tissue, decreased SOD activity and LC3Ⅱ/Ⅰ, PCNA value, and elevated levels of p62, MDA, ROS, and LGR5 (P<0.05). Compared with the model group, different doses of Renshen Baidusan decreased the TDI score, promoted the generation of new goblet cells, elevated the levels of PCNA, LGR5, SOD, and LC3Ⅱ/Ⅰ, and lowered the levels of p62, MDA, and ROS (P<0.05). Moreover, the low dose group showed the best performance (P<0.05). ConclusionRenshen Baidusan can promote intestinal epithelial repair by activating intestinal autophagy, alleviating oxidative stress, and promoting intestinal stem cell proliferation and differentiation.
