Abstract
BACKGROUND Sleep disorders are associated with temporomandibular disorders (TMDs). Limited studies have focused on excessive daytime sleepiness (EDS) and its impact on jaw functions in TMD patients. OBJECTIVE The aim of the present investigation was to identify the impact of EDS on pain and jaw function in TMD patients. METHODS A total of 338 TMD patients (50 males and 288 females) was included. The Epworth Sleepiness Scale (ESS) was used to classify patients into EDS group (score ≥ 10) and non-EDS group (score < 10). The Jaw Functional Limitation Scale 8-item (JFLS-8) was used to assess the severity of jaw dysfunction. Pain intensity was evaluated using the Visual Analogue Scale (VAS). Anxiety and depression were evaluated using the Generalised Anxiety Disorder 7-item (GAD-7) and the Patient Health Questionnaire 9-item (PHQ-9). All included patients were diagnosed with pain-related TMD (PT), intra-articular TMD (IT) or combined TMD (CT). RESULTS Compared with non-EDS patients, EDS patients exhibited more severe jaw dysfunction, greater pain intensity and higher PHQ-9 scores (p < .05). Multivariate analyses showed that EDS (B = 3.69), female gender (B = 3.69), and elevated GAD-7 score (B = 0.73) were significantly associated with an increased score on the JFLS-8 (p < .05). Moreover, bivariate logistic regression analysis indicated a significant relationship between EDS and PT (OR = 2.70, p = .007). CONCLUSION The presence of EDS was more closely related to PT, but the causal relationship between them needs to be further confirmed. More concern and intervention to alleviate poor sleep quality might be highlighted during the treatment of TMD, especially PT subtype.

Abstract
Objective To evaluate the prevalence of different types of temporomandibular disorders (TMD) symptoms in young adults and determine their associations with problematic smartphone use (PSU). Methods The data of the study were collected from local university students through an online questionnaire survey. Demographic information, Fonseca Anamnestic Index (FAI), Smartphone Addiction Scale-Short Version (SAS-SV), and Patient Health Questionnaire-4 (PHQ-4) responses were gathered electronically and analyzed using multiple logistic regression analysis. Results There were 163 male and 307 female respondents were participated in this study. The prevalence of PSU and TMD were 83.6% and 66.4%, respectively. There was a moderate statistical correlation between PSU and TMD among young adults (r = 0.31, p < 0.01). The logistic regression model revealed that the risk of TMD was 1.77 times higher in people with PSU than in those without PSU (OR = 1.77; 95% CI 1.04-3.06). PSU is a risk factor for pain-related TMD (OR = 1.81; 95% CI 1.08-3.04) but not intra-articular TMD. Conclusion Subjects showed high prevalence of both TMD and PSU. People with PSU experienced more severe and frequent pain-related rather than intra-articular TMD symptoms than those without PSU. By reducing the problematic smartphone use, the risk factor of TMD might be avoided.

Abstract
lnterleukin-4 (IL-4) has been shown to play a crucial role in the pathogenesis of allergic disease including bronchial asthma. In order to investigate the role of IL-4 in airway hyperreactivity, we investigated the effect of inhaled recombinant human IL-4 on airway responsiveness to methacholine and eosinophil numbers in induced sputum in eight patients with allergic asthma using a placebo-controlled study design. Our results demonstrated that in the control experiments receiving vehicle inhalation, methacholine PC20 values did not change nor did the numbers of eosinophils in sputum change from baseline values. In contrast, after IL-4 inhalation, methacholine PC20 fell from baseline (0.43 +/- 1.81 mg/mI) to 0.22 +/- 1.73 mg/mI (p < 0.01) at 24 h, and to 0.21 +/- 1. 74 mg/ml (p < 0.01) at 48 h. Accompanying this increased airway sensitivity was a significant eosinophilia in sputum. Our data indicated that IL-4 increases airway responsiveness by recruiting eosinophils into the airway in patients with allergic bronchial asthma.

Abstract
In order to investigate the role of interleukin-5 (IL-5) in airway hyperreactivity and eosinophilia, we observed the effect of inhaled recombinant human IL-5 on airway responsiveness to methacholine and cell populations in induced sputum in eight patients with allergic bronchial asthma using a placebo-controlled study design. Our results demonstrated that the inhalation of IL-5 did not alter lung function in allergic asthmatics. In the control experiments receiving either vehicle or 0.4 ng of endotoxin, methacholine PC20 values did not change nor did the numbers of eosinophils or eosinophil cationic protein (ECP) sputum values change from baseline. In contrast, after IL-5 inhalation, methacholine PC20 fell from baseline (0.90 +/- 166 mg/ml) to 0.32 +/- 1.63 mg/ml (p < 0.01) at 24 h, and to 0.55 +/- 1.49 mg/ml (p < 0.05) at 48 h. Accompanying this increased airway sensitivity was a significant eosinophilia and elevated concentrations of ECP in induced sputum. Our data provided direct evidence that IL-5 increases airway responsiveness and infiltration of activated eosinophils into the airway in patients with allergic bronchial asthma. It also could be concluded that the observed airway hyperreactivity and eosinophilia were not endotoxin related.

Abstract
A clinical study on 59 remote myocardial infarction cases were divided randomly into treated group (31 cases) and normal control group (28 cases). Treated group used intravenously injected Ligustrazine 160 mg a day for 10 days. The plasma lipid peroxidation (LPO), superoxide dismutase (SOD) and sulfhydryl group were measured before and after treatment in the treated group, in comparing with normal control group. The results showed the levels of LPO significantly reduced (P < 0.01), and SOD, sulfhydryl group was obviously increased after Ligustrazine administration (P < 0.05). Attack of angina pectoris was reduced. Between these two group, the difference was significant (P < 0.05). Mechanism of Ligustrazine in reducing LPO and increasing SOD could be the inhibiting of platelet aggregation, regulating the TXA2/PGI2 ratio in plasma, protecting myocardial cell membrane and improving the myocardial ischemia. Ligustrazine could reduce the production of LPO due to the accelerating clearance of oxygen free radical.
