ABSTRACT
Objective:To investigate the current status and influencing factors of stroke patients.Methods:Using stratified sampling method, 458 stroke patients was investigated for the health behavior from October to December, 2015. Based on PROCEDE-PROCEED model, logistic regression analysis was conducted with the health behavior level of the subjects as the dependent variable, and the characteristic factors in the chi-square test as the independent variables to analyze the factors which influence the health behavior level of stroke patients from predisposing factors, enabling factors and reinforcing factors.Results:The health behavior score of stroke patients was (14.5±3.9), which was at medium level. The score of each dimension was nutrition (0.80±0.25), disease management (0.60±0.26), interpersonal relationship (0.57±0.33), and medication compliance (0.49±0.41). The multiple logistic regression analysis showed that the predisposition factors including age ( OR=2.03, 95% CI=1.08-3.80) and history of hypertension( OR=2.35, 95%=1.16-4.76), the enabling factors including the allocation of social resources ( OR=1.73, 95% CI=0.89-3.36), and the reinforcing factors including family support ( OR=2.03, 95% CI=0.99-4.17) were important factors which affect the health behavior of stroke patients. Conclusion:The health behavior level of stroke patients need to be improved. The relevant community resource allocation system continuously, and focus on the impact of family environment and particularly the elderly and patients with a history of hypertension should be attentioned when improving the health behavior of patients.
ABSTRACT
OBJECTIVE:To observe effects and safety of Kangfuxin solution combined with intense pulsed light in the treat-ment of rosacea. METHODS:A total of 50 rosacea patients in our hospital during May 2014-Jun. 2016 were divided into control group(25 cases)and observation group(25 cases)according to random number table. Based on oral administration of Metronida-zole tablets,control group received intense pulsed light. Observation group was additionally given Kangfuxin solution for local wet compress after 4 to 6 layers of gauze saturated with liquid,5-10 min,qn. Both groups received treatment for 4 weeks. Clinical effi-cacies,as well as symptom score and DLQI score were compared between 2 groups before and after treatment,and the occurrence of ADR was recorded. RESULTS:The response rate of observation group was 92.0%,which was significantly higher than 64.0%of control group,with statistical significance (P0.05). After treatment,erythe-ma,papules,pustules,itching,telangiectasia score and total score,DLQI score of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The incidence of ADR in observation group was 16.0%,which was significantly lower than 40.0% in control group,with statistical significance(P<0.05). CONCLUSIONS:Kangfuxin solution combined with intense pulsed light show significant efficacy for rosacea,and can effectively improve erythema,papules,pustules,itching and telangiectasia,and improve the quality of life with good safety.
ABSTRACT
Objective To investigate the mechanism of miR-758 in hepatocellular carcinoma cell HepG2,and to investigate the regulatory role of miR-758 on astrocyte elevated gene-1 (AEG-1).Methods Transient transfection of miR-758 into HepG2 cells was performed to study the effect of miR-758 on tumor cell metastasis by transwell migration and invasion experiments.CCK8 assay was used to detect the cell proliferation activity.The cell cycle was analyzed by flow cytometry.The effect of miR-758 on epidermal mesenchymal transition (EMT) was determined by the expression of EMT markers.Transient transfection of miR-758 into human umbilical vein endothelial cells (HUVECs) was performed to explore the effect of miR-758 on luminal formation.AEG-1 3'UTR containing the binding site of miR-758 was constructed into luciferase expression vector.The miR-758 and the vector was co-transfected into HepG2 cells.And then the change in expression level of AEG-1 protein was detected through Western Blot.Results The overexpression of miR-758 inhibited HepG2 cell migration and invasion,as well as the cell proliferation and the cell cycle.The miR-758 was also found to inhibit EMT of HepG2 cells and the lumen formation of HUVEC cells.After the co-transfection of miR-758 with the plasmid containing AEG-1 gene 3'UTR into HepG2 cells,the luciferase expression was decreased.The luciferase expression was restored when the binding site of miR-758 in the 3'UTR was mutated.Further evidence by Western Blot showed the protein level of AEG-1 in HepG2 cells was significantly decreased after transfection of miR-758.Conclusions The miR-758 negatively regulates multiple steps during cancer metastasis,including cell migration,invasion,cell proliferation,EMT,as well as angiogenesis.And AEG-1 has been identified as a downstream target of miR-758.
ABSTRACT
ObjectiveTo investigate the relevant risk factors for early recurrence after microwave ablation for primary hepatocellular carcinoma (HCC), and to provide a reference for predicting and preventing tumor recurrence. MethodsA retrospective analysis was conducted on the clinical data of 80 patients who had undergone microwave ablation for primary HCC at the Beijing You′an Hospital, Capital Medical University, Beijing, China (2010-2012). Factors possibly influencing early recurrence were selected for univariate analysis using logistic model. Risk factors for early recurrence of HCC after ablation were screened out for identifying the high-risk population and further guiding treatments against recurrence. ResultsThere were 30 cases of recurrence in 6 months after ablation, accounting for a recurrence rate of 375%. Univariate analysis showed that no significant differences occurred between the recurrence and non-recurrence groups in age, gender, tumor location and size, family history of HCC, drinking history, HCC resection history, preoperative alpha-fetoprotein level, liver function Child-Pugh grade, MELD score, or HCC-related causes (P＞0.05). In contrast, the number of tumors (≥2) significantly differed between the two groups (P=0.008). ConclusionThe number of tumors is an independent risk factor for early recurrence among patients after microwave ablation for HCC. High-risk population can be predicted according to the risk factors for early recurrence after microwave ablation for HCC. Targeted preventive measures should be taken for early detection and timely treatment of tumor recurrence.
ABSTRACT
OBJECTIVE:To observe the effect of Compound glycyrrhizin on serum VEGF of patients with alopecia areata. METHODS:36 alopecia areata patients were selected as trial group and treated with Compound glycyrrhizin(50 mg/time,3 times/d) for 3 months. Double-antibody sandwich ELISA method was adopted to determine the content of VEGF in serum before and after treatment. 36 healthy volunteers were included in control group,and serum content of VEGF in control group was compared with trial group. RESULTS:Compared with control group,the serum content of VEGF was lower in trial group,with statistical signifi-cance(t=5.863,P0.05). CONCLUSIONS:Compound glycyrrhizin can cure alopecia areata through increasing serum level of VEGF.
