In recent years, the number of outpatients in stomatological hospital is in increasing year by year and being accompanied by the corresponding medical risks. One of the risks which may endanger the patient life is medical emergency which need emergency treatment by the dentists in dental clinical practice. The most common emergency type is syncope, followed by hyperventilation, drug overdose, adrenaline reaction and hypertension, etc. Unexpected events mainly occurred at the end of the treatment and before leaving the dental clinic, during or immediately after the local anesthesia, in the treatment process. Tooth extraction related emergency is the most frequently occurring emergency, followed by the local anesthesia related ones. It's strongly suggested that dentists should pay more attention to outpatient clinical emergency treatment, and related knowledge and skills training should be offered to improve the ability to handle medical emergencies.

High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.

OBJECTIVETo assess the efficacy of Dexamethasone (DM) pericoronal injection for the control of swelling and trismus caused by impacted mandibular third molars extraction.

METHODSCochrane, PUBMED, EMBASE and CBM were searched for eligible studies. Hand-searching included references of the included studies and Chinese dental journals. Risk of bias of the included studies was assessed by two reviewers independently using Cochrane Collaboration's tool, and data extraction was done by them. Meta-analysis was delivered with Revman 5.1.

RESULTSSeven randomized controlled trials, involving 684 participants, were included. Six of them had moderate risk of bias and one had high risk of bias. Meta-analysis showed that DM pericoronal injection could relieve trismus by 6.77 mm (P=0.02) within 1-2 days after the surgery. It could also reduce 51% of the risk of moderate-severe trismus(P<0.000 01) and could significantly control facial swelling (P<0.05). There was no differences between 4 mg and 8 mg DM (P>0.05).

CONCLUSIONPeriodontal injection of 4-5 mg DM could control facial swelling and trismus following impacted mandibular third molar extraction. But more randomized controlled trials are needed.

OBJECTIVETo compare the effects of video or leaflet in conjunction with traditional patient education (TPE) with traditional patient education alone for the compliance and satisfaction of the patients with temporomandibular disorders (TMD).

METHODSOne hundred and thirty-three patients with TMD who needed intra-articular injection of hyaluronate were included and randomly divided into three groups: Group I accepted video education plus TPE, Group II accepted leaflet education plus TPE, Group III accepted TPE alone. All the participants were recorded by demographic characteristics (sex, age) before treatment, and their compliance, satisfaction and self-exercise were also recorded after one month followed-up.

RESULTSThe baseline parameters (sex, age and diagnosis) of the groups were similar (P > 0.05). Seventeen participants lost in follow-up, including 4.5% in Group I, 11.1% in Group II and 22.7% in Group III. There were significant differences in lost rates among the three groups (P = 0.035). The rates of participants who exactly followed the appointed follow-up were higher in Group I and II than in group III (P = 0.04). And the satisfaction rates were 90.5% in Group I, 92.5% in Group II, 76.5% in Group III. The satisfaction rates of Group I and Group II were significantly higher than that of Group III (P = 0.05). The patients in Group I and Group II were more compliant with the self-exercise than that in Group III (P = 0.007).

CONCLUSIONAdding video or leaflet education to the TPE could increase the patients' compliance, satisfaction and execution of the self-exercise.

OBJECTIVE: To analyze the effect of occupational stress on abnormity of serum total cholesterol and triglyceride in male steel workers. METHODS: A total of 3 957 male steel workers from an iron and steel group company were selected as study objects by judgment sampling method. Occupational stress was measured by the Chinese version of Job Content Questionnaire. The serum total cholesterol and triglyceride levels were measured using fasting venous blood. RESULTS: Among the 3 957 workers,the detection rate of occupational stress was 56. 8%,and 55. 0% of them showed high social support. The abnormal rates of total cholesterol and triglyceride were 21. 8% and 40. 9%,respectively. The multivariate logistic regression analysis showed that workers with high social support had high risk of abnormal total cholesterol and abnormal triglyceride than workers with low social support( P < 0. 05) after adjusting for confounding factors such as age,education level,marital status,body mass index,smoking and drinking alcohol,tea. The odds ratio of abnormal total cholesterol in occupational stress workers was 1. 17 times of that of non-occupational stress workers. No association was found between occupational stress and abnormal triglyceride( P > 0. 05). CONCLUSION: Occupational stress may be associated with abnormity of total cholesterol in male steel workers. Social support is an important influences factor to the abnormity of total cholesterol and triglyceride in male steel workers.
