Objective:To investigate the efficacy and safety of precise mechanical thrombectomy based on ABC 2D scale in acute intracranial large artery occlusion stroke (ALVOs). Methods:A prospective study was performed. Two hundred and two patients with ALVOs accepted early mechanical thrombectomy in Department of Neurology, Maoming Clinical School of Guangdong Medical University from January 2021 to February 2022 were enrolled. They were randomly divided into experimental group ( n=102) and control group ( n=100). Stent retriever partially retracted with intermediate catheter for mechanical thrombectomy (SWIM) was the first choice for patients in control group. ABC 2D scale was used to prejudge the pathogenesis of patients in experimental group: patients with scores of 0-3 were considered as having embolic occlusion and a direct aspiration first pass technique (ADAPT) was the first choice, and SWIM would be chosen if suction catheter could not be in place; patients with scores of 4-7 were considered as having intracranial atherosclerotic stenosis occlusion and SWIM was the first choice. The clinical data, surgical effectiveness, surgical safety, and good prognosis rate 90 d after mechanical thrombectomy (modified Rankin scale scores of 0-2 as good prognosis) of the 2 groups were compared. Results:Experimental group had significantly shorter time from puncture to recanalization (51.0[35.0, 78.5] min vs. 67.0[45.0, 100.0] min), and statistically lower NIHSS scores 24 h after mechanical thrombectomy (10.00[4.75, 16.25] vs. 13.00[8.00, 19.00]), significantly higher good prognosis rate 90 d after mechanical thrombectomy (69.6% vs. 46.0%), statistically lower mortality 90 d after mechanical thrombectomy (3.9% vs. 13.0%) compared with control group ( P<0.05). No significant differences were noted in first-pass effect rate, successful vascular revascularization rate, or incidences of symptomatic intracranial hemorrhage (sICH) and ectopic embolization between the control group and experimental group ( P>0.05). Conclusion:Patients with ALVOs accepted early mechanical thrombectomy can have shorter time from puncture to vascular recanalization and better prognosis after etiologically prejudging by ABC 2D scale for thrombectomy.

Objective: To compare the impact of different prognostic scores in patients with acute-on-chronic liver failure (ACLF) in order to provide treatment guidance for liver transplantation. Methods: The information on inpatients with ACLF admitted at Beijing You'an Hospital Affiliated to Capital Medical University and the First Affiliated Hospital of Zhejiang University School of Medicine from January 2015 to October 2022 was collected retrospectively. ACLF patients were divided into liver transplantation and non-liver transplantation groups, and the two groups prognostic conditions were followed-up. Propensity score matching was carried out between the two groups on the basis of liver disease (non-cirrhosis, compensated cirrhosis, and decompensated cirrhosis), the model for end-stage liver disease incorporating serum sodium (MELD-Na), and ACLF classification as matching factors. The prognostic condition of the two groups after matching was compared. The difference in 1-year survival rate between the two groups was analyzed under different ACLF grades and MELD-Na scores. The independent sample t-test or rank sum test was used for inter-group comparison, and the χ (2) test was used for the comparison of count data between groups. Results: In total, 865 ACLF inpatients were collected over the study period. Of these, 291 had liver transplantation and 574 did not. The overall survival rates at 28, 90, and 360 days were 78%, 66%, and 62%, respectively. There were 270 cases of matched ACLF post-liver transplantation and 270 cases without ACLF, in accordance with a ratio of 1:1. At 28, 90, and 360 days, patients with non-liver transplantation had significantly lower survival rates (68%, 53%, and 49%) than patients with liver transplantation (87%, 87%, and 78%, respectively; P < 0.001). Patients were classified into four groups according to the ACLF classification criteria. Kaplan-Meier survival analysis showed that the survival rates of liver transplantation and non-liver transplantation patients in ACLF grade 0 were 77.2% and 69.4%, respectively, with no statistically significant difference (P = 0.168). The survival rate with an ACLF 1-3 grade was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.05). Patients with ACLF grades 1, 2, and 3 had higher 1-year survival rates compared to non-liver transplant patients by 50.6%, 43.6%, and 61.7%, respectively. Patients were divided into four groups according to the MELD-Na score. Among the patients with a MELD-Na score of < 25, the 1-year survival rates for liver transplantation and non-liver transplantation were 78.2% and 74.0%, respectively, and the difference was not statistically significant (P = 0.149). However, among patients with MELD-Na scores of 25-30, 30-35, and≥35, the survival rate was significantly higher in liver transplantation than that of non-liver transplantation, and the 1-year survival rate increased by 36.4%, 54.9%, and 62.5%, respectively (P < 0.001). Further analysis of the prognosis of patients with different ACLF grades and MELD-Na scores showed that ACLF grades 0 or 1 and MELD-Na score of < 30 had no statistically significant difference in the 1-year survival rate between liver transplantation and non-liver transplantation (P > 0.05), but in patients with MELD-Na score≥30, the 1-year survival rate of liver transplantation was higher than that of non-liver transplantation patients (P < 0.05). In the ACLF grade 0 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 77.8% and 25.0% respectively (P < 0.05); while in the ACLF grade 1 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 100% and 20.0%, respectively (P < 0.01). Among patients with ACLF grade 2, the 1-year survival rate with MELD-Na score of < 25 in patients with liver transplantation was 73.9% and 61.6%, respectively, and the difference was not statistically significant (P > 0.05); while in the liver transplantation patients group with MELD-Na score of ≥25, the 1-year survival rate was 79.5%, 80.8%, and 75%, respectively, which was significantly higher than that of non-liver transplantation patients (36.6%, 27.6%, 15.0%) (P < 0.001). Among patients with ACLF grade 3, regardless of the MELD-Na score, the 1-year survival rate was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.01). Additionally, among patients with non-liver transplantation with an ACLF grade 0~1 and a MELD-Na score of < 30 at admission, 99.4% survived 1 year and still had an ACLF grade 0-1 at discharge, while 70% of deaths progressed to ACLF grade 2-3. Conclusion: Both the MELD-Na score and the EASL-CLIF C ACLF classification are capable of guiding liver transplantation; however, no single model possesses a consistent and precise prediction ability. Therefore, the combined application of the two models is necessary for comprehensive and dynamic evaluation, but the clinical application is relatively complex. A simplified prognostic model and a risk assessment model will be required in the future to improve patient prognosis as well as the effectiveness and efficiency of liver transplantation.

AIM: To investigate the impact of meteorological factors in different environments in the eastern and western regions of China on the incidence of lipid-abnormal dry eye.METHODS: This is a multicenter retrospective study. From March 1, 2021 to February 28, 2022, all patients with dry eye were selected from the ophthalmology clinic of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine and Friendship Hospital of Xinjiang Yili Kazakh Autonomous Prefecture. General data(gender, age, employment and education)and climate data for outdoor environments(temperature, humidity, air quality index and wind)on the day of the visit were collected. Patients who met the inclusion and exclusion criteria were selected. Single factor, multiple factors and nonlinear model analysis were applied to identify environmental factors of lipid-abnormal dry eye in both regions.RESULTS: There was no significant difference in the incidence of lipid-abnormal dry eye between Nanjing and Yili in different seasons. The incidence of lipid-abnormal dry eye in Yili was significantly higher in all seasons than in Nanjing(P<0.001). The results of univariate research showed that the factors affecting the incidence of lipid-abnormal dry eye were gender, employment, humidity, air quality, and wind. The results of multivariate Logistic regression analysis showed that humidity, temperature and air quality were statistically significant, and remained significant after adjusting for the three confounding factors of age, gender and employment situation. Nonlinear analysis showed that the probability of lipid-abnormal dry eye increased with the decrease of temperature when the temperature was below 10℃; within the range of 10℃～15℃, the probability of lipid-abnormal dry eye tended to stabilize. When the temperature exceeded 15℃, the probability of lipid-abnormal dry eye increased with the increase of temperature. Humidity was negatively correlated with the onset of lipid-abnormal dry eye. As humidity increased, the probability of lipid-abnormal dry eye decreased.CONCLUSIONS: The risk of lipid-abnormal dry eye in Yili is higher than that in Nanjing throughout the four seasons. Humidity, temperature, air quality and other environmental and meteorological factors can all affect the incidence of lipid-abnormal dry eye.

This study aimed to explore the effects of Gynostemma pentaphyllum saponins(GPs) on non-alcoholic fatty liver disease(NAFLD) induced by high-fat diet in rats and reveal the underlying mechanism. The NAFLD model rats were prepared with high-fat diet. Forty male Sprague Dawley(SD) rats were randomly assigned into the control group, model group, and low-, moderate-, and high-dose GPs(50, 100, and 150 mg·kg~(-1), respectively) groups. After intragastric administration for 8 continuous weeks, we determined the body weight, liver weight, the levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein cholesterol(LDL-c), high-density lipoprotein cholesterol(HDL-c), alanine aminotransferase(ALT), and aspartate aminotransferase(AST) in serum, and the levels of TC, TG, malondialdehyde(MDA), superoxide dismutase(SOD), catalase(CAT), and interleukin 6(IL-6) in the liver. Furthermore, we observed the pathological changes of liver tissue by oil red O staining and hematoxylin-eosin(HE) staining, sequenced the 16 S rRNA of the intestinal flora in rat feces, and determined the content of short-chain fatty acids in rat feces. The results showed that GPs inhibited the excessive weight gain of high-fat diet-induced NAFLD in rats, reduced the liver weight, lowered the TC, TG, LDL-c, AST, and ALT levels in serum(P<0.05), and rose the HDL-c level in serum(P<0.01). GPs relieved the liver damage caused by high-fat diet, mainly manifested by the lowered levels of TC, TG, MDA, and IL-6 in the liver(P<0.01) and elevated levels of CAT and SOD in the liver. Furthermore, GPs reversed the intestinal flora disorder caused by high-fat diet, restored the diversity of intestinal flora, increased the relative abundance of Bacteroides, and reduced the relative abundance of Firmicutes and the ratio of Firmicutes to Bacteroides. Moreover, GPs promoted the proliferation of beneficial bacteria such as Akkermansia, Bacteroides, and Parabacteroides, and inhibited the growth of harmful bacteria such as Desulfovibrio, Escherichia-Shigella, and Helicobacter. GPs increased the content of short-chain fatty acids(acetic acid, propionic acid, and butyric acid)(P<0.01). These findings indicate that GPs can alleviate the high-fat diet-induced NAFLD in rats via regulating the intestinal flora and short-chain fatty acid metabolism.
