BACKGROUND:Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. METHODS:We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients. RESULTS:Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratio of male to female was 1:1.04, and their average age was 33.8 years. Of the 2867 patients, 76.39％ were between 18 and 40 years old. The incidence of acute poisoning was as high as 11.33％ in January each year. The incidence of poisoning was in a descending order:alcohol poisoning (54.55％), medication poisoning (25.95％), pesticide poisoning (5.65％), and drug poisoning (4.88％). Most (56.44％) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning (P < 0.01). Approximately 69.54％ of the patients were followed up after emergency treatment, 30.39％ were hospitalized, and four patients died. CONCLUSIONS:Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment"can significantly improve the survival rate of patients with acute poisoning.

OBJECTIVEThis study aimed to investigate the effects of different tooth preparations on the fracture strength and pattern of failure of teeth with severe wedge-shaped defect restored with post and core crowns.

METHODSAccording to whether the teeth above the wedge-shaped defect was removed (represented by B) or not (represented by A), the ferrule next to the wedge-shaped defect was prepared (represented by D) or not (represented by C), the cast post-and-core was chosen (represented by E) or glass-fiber post and resin core was chosen (represented by F). A total of 64 human mandibular premolar teeth were randomly divided into 8 groups: A1-1 (A + C + E), A1-2 (A + C + F), A2-1 (A + D + E), A2-2 (A + D + F), B1-1 (B + C + E), B1-2 (B + C + F), B2-1 (B + D + E), B2-2 (B + D + F), each group 8 teeth. All the teeth were prepared and restored accordingly and then mounted on an electronic pressure universal testing machine. The maximum fracture strength and the patterns of failure were recorded.

RESULTS1) The fracture strength of Group A1-1 > that of Group B1-1, Group A1-2 > Group B1-2, Group B2-1 > Group B1-1, and Group B2-1 > Group B2-2 with significant differences (P < 0.05). 2) The patterns of repairable fracture in Group A1-2 and B1-2 were both 37.5%, and that of the other groups were 0. Furthermore, the difference was significant, and Group A1-2 and B1-2 were higher than other groups.

CONCLUSIONThe maintenance of the overhang above the severe wedge-shaped defect aid in the improvement of the fracture strength of the tooth restored with post and core crown. The ferrule of the wedge-shaped defect is not recommended to be prepared. Furthermore, the glass-fiber post and resin core is favorable for the re-repair of the teeth than the cast post and core.

Objective To describe the disease characteristics of obese patients with polycystic ovary syndrome (PCOS) using the obesity core set of the obesity International Classification of Functioning,Disability and Health (ICF) to reveal the related dysfunction domains.Methods Sixty obese patients with PCOS were evaluated by using the ICF's obesity comprehensive core set.Categories reported as a problem by at least 30％ of the patients were considered as a relevant functional profile for PCOS patients.Results In obese 60 patients with PCOS,20 items were selected from 109 items of obesity ICF comprehensive core set and considered as the relevant functional characteristics for PCOS among the obese,in which 6 items of body functions (30％ of all selected items),1 item of body structures (5％ of all selected items),and 13 items of environmental factors (65％ of all selected items) were included.Conclusions The obesity core set of the ICF can be applied to describe the disease characteristics and dysfunction of obese patients with PCOS,which offers the possibility of clinic application of the ICF core set for PCOS.

Objective:To discuss the effect of radiation of Nd:YAG laser in apical retrograde filling. Methods: 50 similar roots were randomly divided into 5 groups.The anatomical crowns were removed at the cementoenamel junction and the remaining roots were treated endodontically with conventional methods before the apical 2 mm were cut and a dish-like hole made in the cutting surface by high speed round bur. Except the first group,each hole were radiated by the Nd:YAG laser for different time or with different patterns and after that,the glass ionomer cement were retrofilled into the hole. A microleakage measurements were carried out and the result were measured and recorded. The hole surface was also observed under electron microscopy. Results:The leakage of the groups with Nd:YAG radiation were decreased significantly(P

BACKGROUND: Good neurological outcome after cardiac arrest (CA) is hard to achieve for clinicians. Experimental and clinical evidence suggests that therapeutic mild hypothermia is beneficial. This study aimed to assess the effectiveness and safety of therapeutic mild hypothermia in patients successfully resuscitated from CA using a meta-analysis. METHODS: We searched the MEDLINE (1966 to April 2012), OVID (1980 to April 2012), EMBASE (1980 to April 2012), Chinese bio-medical literature & retrieval system (CBM) (1978 to April 2012), Chinese medical current contents (CMCC) (1995 to April 2012), and Chinese medical academic conference (CMAC) (1994 to April 2012). Studies were included if 1) the study design was a randomized controlled trial (RCT); 2) the study population included patients successfully resuscitated from CA, and received either standard post-resuscitation care with normothermia or mild hypothermia;3) the study provided data on good neurologic outcome and survival to hospital discharge. Relative risk (RR) and 95% confidence interval (CI) were used to pool the effect. RESULTS: The study included four RCTs with a total of 417 patients successfully resuscitated from CA. Compared to standard post-resuscitation care with normothermia, patients in the hypothermia group were more likely to have good neurologic outcome (RR=1.43, 95% CI 1.14–1.80, P=0.002) and were more likely to survive to hospital discharge (RR=1.32, 95% CI 1.08–1.63, P=0.008). There was no significant difference in adverse events between the normothermia and hypothermia groups (P>0.05), nor heterogeneity and publication bias. CONCLUSION: Therapeutic mild hypothermia improves neurologic outcome and survival in patients successfully resuscitated from CA.
