Objective To explore the effect of psychological resilience and mood on mental health of leftbehind children.Methods Positive and Negative Affect schedule (PANAS),the Resilience Scale for Chinese Adolescent (RSCA) and Mental Health Scale of Middle School Student (MSSMHS) were administrated to 796 left-behind children.Results ①Positive/negative emotions could significantly predict psychological resilience (β=0.875,P<0.01 ; β=-0.713,P<0.01).②Psychological resilience had significantly negatively forecast mental health (β=-0.759,P<0.01).③The relationship between negative affect and mental health was partially mediated by psychological resilience (P<0.01).The relationship between positive affect and mental health was completely mediated by psychological resilience.Conclusion Psychological resilience plays an important role in the relationship between positive/negative emotions and mental health.Positive affect can improve mental health of left-behind children through psychological resilience.

[Objective] To observe the effects of Oysters, Abalone shel , Concha arcae, Mother-of-pearl, Concha cypraeae, Clamshel , these six testacean TCM on the goiter rats. [Method] 72 healthy SD rats were randomly divided into nine groups:normal group, model group, positive group and six testacean TCM groups. Rats were given daily propylthiouracil (0.15 g·kg-1), continuous modeling for 10d, weighing thyroid wet weight,assaying T3, T4 and TSH contents in serum by ELISA, observing the morphological changes of thyroid under light microscope. [Result] Rats in the model group compared with normal group in-creased the relative weight of thyroid, reduced the content of T3,T4, and there was a significant difference( P<0.01), thyroid fol icular epithelial cellhyperplasia was obvious;compared with the model group, Oysters and Clamshel group made the content of T3,T4 in rat rebound, and there was a significant difference (P<0.05);Oyster and Clamshel group’s thyroid fol icular cellhyperplasia were not obvious, while the hyperplasia had different levels for the other 4 kinds of testacean TCM. [Conclusion] Oysters and Clamshel were better to improve the thyroid function of the goiter model rats.

It has been demonstrated that connective tissue growth factor(CTGF) may enhance proliferation and differentiation of osteoblasts,inhibit the functions of osteoblasts,increase osteoclastogenesis in patients with Rheumatoid Arthritis,stimulate proliferation and differentiation of chondrocytes,and induce angiogenesis in vivo and vitro.Above all,CTGF plays an important role in sustaining growth of skeleton and cartilage,and thus maintaining bone quantity.

Objective To discuss the levels of inhibitory protein Ga-2 (Gαi2) in hippocampus of brain and the effects of Gαi2 on neuronal intracellular Ca2+ level in cerebral ischemia reperfusion injury model of rats.Methods Ninety SD rats were randomly (random number) assigned to sham group (n =30),ischemic-reperfusion (IR) group (n =30),Pertussis toxin (PT) group (n =30).The blood flow of right common carotid artery of rat was blocked for 90 min to make ischemia reperfusion model.The levels of Gαi2 in hippocampus was assayed by immunohistochemistry and Western blotting after ischemia reperfusion for 6,12,24 h in each group.The average fluorescence values of intracellular Ca2+ levels in hippocampus of rats in three groups were detected by using Flow CytoMeter (FCM).Neuronal cell apoptosis was measured by TUNEL.Results After restoration of middle cerebral artery blood flow for different lengths of time,the levels of hippocampus Gαi2 and Ca2+ levels in IR group were significantly higher than those in Sham group (P <0.01).The hippocampus Ca2+ levels in PT group were higher than those in IR group (P < 0.01).The apoptotic rates of neurons in PT group were lower than those in IR group (P <0.05).Conclusions The level of Gαi2 in cerebral ischemia reperfusion injury model was increased.Gαi2 might reduce the calcium ion concentration of neurons after cerebral ischemia and rcduce the neuronal cell apoptosis in this model.Gαi2 might play a role in protecting neuron from cerebral ischemia reperfusion injury.

Methods: Pendulum appliances were applied for distalization of maxillary molars in 37 patients whith class Ⅱ malocclusion and 1-Ⅱ degree crowded dentition in upper dental arch. Pretreatment and posttreatment model analysis was conducted. Results: 37 patients treated for 18.2?4.5 weeks with pendulum appliance were accomplished . The increase of arch arc length between the maxillary first molars was (17.36?4.38) mm, the decrease of anterior arch width (-3.04?1.59) mm, and the decrease of posterior arch width (-1.29?2.01) mm . Differences between the pretreatment and posttreatment were significant, including arch arc length between the maxillary first molars ( P

Sepsis has poor prognosis, and its pathogenesis is not clear. Chemokine CX3CL1 (Fractalkine, FNK) has many functions such as chemotaxis, adhesion and mediate immune injury. CX3CR1 is the only receptor of CX3CL1 and participates in the development of sepsis. Here we review the structure, biological function and possible mechanism of CX3CL1 and CX3CR1 in the pathogenesis of sepsis.

Objective:To evaluate effects of traction arch combined with protraction on dental and skeletal changes in patients with Angel Ⅲ malocclusion in mixed dentition.Methods:Seventeen patients with Angle Ⅲ malocclusion were selected and treated with traction arch combined with protraction. Cephalometric radiographs were taken 6 months before the initiation of treatment, at the initiation of treatment and 6 months after treatment.Cephalometric analysis was used to examine the dental and skeletal changes.Results:Significant changes of maxillary anterior displacement and mandibular downward and backward rotation were observed in the seventeen patients:SNA increased 2.6?,A point moved forward 3.1 mm. The overjet correction of anterior teeth was 5.2 mm, 63% of the overjet correction was due to skeletal changes and 37% due to dental changes. Conclusion:Traction arch combined with protraction is a simple and effective apparatus in the treatment of Angle Ⅲ malocclusion.
