Objective To investigate the implementation effect of group health education mode in cataract department. Methods Through the establishment of clinical health education path and repeatedly broadcast in group health education after surgery for 1200 cases of cataract patients,effect of health education and satisfaction on surgery were assessed and surveyed. Results Knowledge of health education was known by about 88.5% of patients or their family;satisfaction with nurse care was up to 95.0%; health education time of the nurses was reduced but their work efficiency was improved. Conclusions Implementation of group health education mode and clinical health education path could satisfy patients' demands of health education in large-scale cataract surgery and ensure the quality of health education.

Objective: To study the mechanism and effect of Chinese medicine Yiqi Tongyang Huatan prescription(益气通阳化痰方,YQTYHT) on hyperlipidemia and atherosclerosis(AS).Methods: The rabbit′s model was established by feeding the food containing high cholesterol,and 32 rabbits were randomly divided into four groups(each n=8): normal group,model group,Huoxue Huayu prescription treatment group(活血化瘀方,HXHY group) and YQTYHT treatment group(YQTYHT group).Before the experiment,at the end of 6 th and 12 th weeks after the experiment,the following items were measured: blood lipids platelet aggregation rate,platelet adhesion rate,malondialdehyde(MDA),endothelin-1(ET-1),nitric oxide(NO),the ratio of the lipid plaque area and the thickness of the endothelial plaque.Results: After feeding the food containing high cholesterol,the blood lipids,platelet aggregation rate,platelet adhesion rate,MDA,ET1,the ratio of lipid plaque area and the thickness of plaque were elevated significantly,while serum NO3-/NO2-decreased significantly in model group.Compared with the model group,the blood lipids were lower in the two treatment groups,and the blood lipid regulating effect in YQTYHT group was significantly better than that in HXHY group.Platelet aggregation rate and platelet adhesion rate of YQTYHT group and HXHY group were lower than those in the model group,but the degree of lowering in YQTYHT group and HXHY group had no significant differences.The serum MDA of YQTYHT group and HXHY group was lower than that in model group,and the lowering effect in YQTYHT group was better than that in HXHY group.YQTYHT group and HXHY group had a significant increase on the level of serum NO3-/NO2-and a decrease on the content of plasma ET-1,furthermore,the effects in the former group were significantly better than those of the latter group.The area of atherosclerotic plaque coverage in aorta and the thickness of plaque of HXHY group were larger than those in YQTYHT group(both P

Abstract: Objective To investigate the expression of serum C-C chemokine 22 (CCL22) and its receptor C-C chemokine receptor 4 (CCR4) in patients with chronic hepatitis B (CHB), and its correlation with liver function indicators and disease progression. Methods A total of 96 patients with CHB who were treated in Neijiang Traditional Chinese Medicine Hospital from October 2021 to November 2022 were recruited as the observation group, and divided into mild group (n=43), moderate group (n=36) and severe group (n=17) , according to the progress of the disease. In addition, 50 healthy people who underwent physical examination in the same hosiptal were selected as the control group. The levels of serum CCL22 mRNA, CCR4 mRNA and liver function indicators [alanine aminotrans-ferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) and albumin (ALB)] were measured. Pearson correlation analysis was performed to analyze the correlation between serum CCL22 and CCR4 levels and liver function indicators and disease severity, and logistic regression was applied to evaluate the factors affecting the progress of CHB patients. Results Compared with the control group, the levels of CCL22 mRNA, CCR4 mRNA, ALT, AST and TBIL in the observation group were obviously higher (P<0.05), the level of ALB was obviously lower (P<0.05); the expression levels of serum CCL22 mRNA, CCR4 mRNA, ALT, AST and TBIL in mild, moderate and severe groups increased in turn, while the expression level of ALB decreased in turn, with significant differences between groups (P<0.05); The levels of serum CCL22 mRNA and CCR4 mRNA were positively correlated with liver function indicators ALT, AST, TBIL levels, and negatively correlated with ALB level (P<0.05); Both CCL22 mRNA and CCR4 mRNA were positively correlated with the severity of the disease (r=0.646, 0.516, P<0.001); the expression levels of CCR4 mRNA, ALT, AST, TBIL and ALB were all factors affecting the development of CHB patients (P<0.05). Conclusions The expression of CCL22 and CCR4 in serum is closely related to liver function index and severity of CHB patients, which can provide reference for clinical evaluation and symptomatic treatment.

Objective:To explore the value of two-dimensional speckle tracking echocardiographic imaging (2D-STI) for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion.
Methods:Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day, 3, 6 months post-PCI to examine left ventricular ejection fraction (LVEF), meanwhile 2D-STI was applied to obtain the global longitudinal strain (GLS) value of left ventricle.
Results:In all 23 patients, for LVEF, compared with pre-PCI (59.29±12.15)%, it was increased at 3 and 6 months post-PCI (60.00±12.35)%and (61.37±11.8)%respectively, all P<0.05;for GLS value, compared with pre-PCI (-12.77d wit )%, it was decreased at 1 day and 3, 6 months post-PCI (-13.23ecrea)%and (-15.67ecrea)%, (-16.97ecrea)%respectively, all P<0.05.
Conclusion:PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion, 2D-STI technology may quantitatively assess those changes at the early stage.

Objective To compare the predicting values for Prognosis among Global Risk Classification (GRS),Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) score,the European System for Cardiac Operative Risk Evaluation (EuroSCORE) in patients who received stenting because of unprotected left main coronary artery (ULMCA) lesion.Methods Totally 105 successive elderly patients with ULMCA lesion who received stenting were divided into 2 groups:with and without main adverse cardiac events (MACE).The clinical and angiographic characteristics were analyzed and then compared among GRC,SYNTAX score and EuroSCORE.Results As compared with none MACE group,MACE group had higher EuroSCORE score (2.0±2.3 vs.6.5±2.9,t=8.18,P=0.002),and more trivessel disease and left main bifurcation lesion (x2 =8.96,6.96,P =0.011,P =0.008).High risk GRC showed more MACE than medium or low risk GRC [55.9％ (19/34) vs.20.5％(9/44),7.4％ (2/27),x2 =19.77,P=0.001].AUC(95％CI )of GRC,SYNTAX score and EuroSCORE were [0.821 (0.730-0.912),0.586(0.462-0.709) and 0.631 (0506-0.757)],respectively.Compared with SYNTAX score and EuroSCORE,GRC was superior in the MACE predicting value (Z=3.29,2.63,P＜0.01 or P＜0.05).
