Objective:To investigate the effect of compound sophora flavescens injection on T helper cells 17 (Th17), regulatory T-cells (Treg cells) and the related cytokines in lung cancer patients with cirrhosis.Methods:A total of 63 patients with early non-small cell lung cancer and cirrhosis in Shouguang People's Hospital of Shandong Province from January 2016 to January 2018 were selected. All patients were scheduled to undergo surgical treatment. The patients were randomly divided into observation group (33 cases) and control group (30 cases) according to the random number table method. The patients in the control group were treated with liver protection, and the patients in the observation group were given compound sophora flavescens on the basis of the control group. After 3 months of treatment, the changes of liver fibrosis index, the levels of Th17 and Treg cells in peripheral blood and the changes of interleukin (IL)-10, IL-17, IL-6, and transforming growth factor (TGF)-β in serum were compared between the two groups.Results:After treatment, the alanine aminotransferase (ALT) of 15 cases (45.45%) in the observation group were normalized and 6 cases (20.00%) in the control group were normalized. There was a significant difference in ALT normalization rate between the two groups ( P < 0.05). The levels of serum laminin (LN) and hyaluronic acid (HA) in the two groups after treatment were lower than those before treatment (all P < 0.05), and the serum LN [(156.74±30.52) ng/ml] and HA [(179.56±25.32) ng/ml] in the observation group after treatment was lower than those in the control group [(210.58±39.42) ng/ml and (203.75±28.79) ng/ml] (t values were 18.236 and 12.184, both P < 0.01). There was no significant difference in the level changes of type Ⅲ procollagen and type Ⅳ collagen between the two groups before and after treatment (all P > 0.05). After treatment, the levels of Th17 and Th17/Treg increased and the level of Treg cells decreased (all P < 0.05). After treatment, the levels of Th17 [(1.32±0.18)%] and Th17/Treg (0.23±0.04) in the observation group were higher than those in the control group [(1.21±0.17)% and 0.20±0.03] (t values were 3.201 and 1.087, both P < 0.01), while the level of Treg cells in the observation group was lower than that in the control group ( P < 0.05). After treatment, the serum levels of IL-10, IL-17, IL-6, and TGF-β in the two groups were lower than those before treatment (all P < 0.05), and their levels in the observation group were lower than those in the control group (all P < 0.05). Conclusion:Compound sophora flavescens injection can improve the liver function and fibrosis index of patients with lung cancer and cirrhosis, and it can regulate the levels of Th17, Treg cells and their related factors, which can be used as a clinical adjuvant.

Objective:To explore the inducing factors of symptom onset in patients with symptomatic carotid artery stenosis, and to provide basis for preventive care.Methods:Totally 104 patients with symptomatic carotid artery stenosis hospitalized in Stroke Ward from September 2014 to December 2017 were selected by convenience sampling method. The clinical data of patients were analyzed retrospectively, and the possible inducing factors were analyzed.Results:there were 104 patients with symptomatic carotid artery stenosis, and 35 patients (33.7%) had obvious inducing factors before onset, but 69 patients (66.3%) had not. The inducing factors were classified into ten categories: posture, activity and fatigue, mood, blood pressure reduction, eating, drinking, noisy environment, hot bath, sweating and cold stimulation. There was no significant difference in gender, age, single and bilateral stenosis, comorbidities (hypertension, diabetes, coronary artery disease, hyperlipidemia) and smoking between the induced group and the non-induced group ( P>0.05). Among the 31 patients with a history of alcohol consumption, 15 had an inducement, accounting for 48.4%; among the 73 patients without a history of alcohol consumption, 20 had an inducement, accounting for 27.4%. The difference between the two groups was statistically significant ( χ 2=4.294, P<0.05).Three cases (8.6%) were directly caused by drinking alcohol. Conclusion:There are many inducing factors for symptomatic carotid artery stenosis, especially for drinking patients, health education should be given, and corresponding preventive measures should be taken to reduce the occurrence of symptoms.

The ischemic heart disease has been endangering human health seriously. Although there are many kinds of anti-ischemic drugs, most of them are lacking in tissue specificity, which together with a remarkably reduced blood circulation in the ischemic zone often lead to a quite low drug distribution in the targets. Myocardial ischemia can cause a lot of pathophysiological changes, such as the enhanced permeability of the endothelial cell membrane, the up-regulated expression of various cell adhesion molecules on endothelium, the exposure of intracellular antigenic components, the decrease of pH within the ischemic zone, and so on. To date, some of these changes have been exploited with limited success to gain the passive, active and physicochemical targeting of diagnostic or therapeutic drugs to myocardial ischemic regions. However, more effective delivery strategies are still eagerly needed. Here, we reviewed and discussed the potential targeting-delivery mechanisms and strategies, used or may be used in the future, for myocardial ischemic regions.

BACKGROUND: Poly methyl methyacrylate (PMMA) has been widely used as a denture base material in dental field for a long time. However, the fracture of acrylic resin dentures is an unresolved problem in prosthodontics. Therefore, how to improve the flexural strength of repaired denture seems to be extremely important. OBJECTIVE: To study the effect of embedding different amounts of metal wires on the flexural strength of repaired denture bases. METHODS: Twenty-five rectangular specimens (50 mm× 30 mm × 2.5 mm) were fabricated using heat-cured acrylic resins and randomly and evenly divided into five groups: A, B, C, D, and E. All specimens were fractured through the use of universal testing machine, and the flexural strengths were tested. Following preparation of fracture surfaces, one to four metal wires were separately embedded in the groups B, C, D, and E. No metal wires were embedded in the group A. All fractured specimens were repaired using self-curing resins. The flexural strengths were measured again using the same testing machine, and the percentages of strength recovery were calculated. RESULTS AND CONCLUSION: After repair, the flexural strengths were obviously reduced (P < 0.01). Compared to group A, the percentages of strength recovery were significantly increased in groups C, D, and E (P < 0.05). There was no significant difference in the percentage of strength recovery among groups C, D, and E (P > 0.05). These results indicate that embedding two to four metal wires can improve the flexural strength of denture bases.
