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.

objective: To evaluate the effects of the pendulum appliance on arch length, arch width, overbite and overjet. 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

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.

[Objective]To investigate the osteogenic ability in vivo of mesenchymal stem cells(MSCs).[Method]Ten-fifteen ml bone marrow aspirates were harvested from the iliac crest of sheep and enriched for MSCs by density gradient centrifugation over a Percoll cushion(1.073 g/ml).After cultured and proliferated,the tissue-engineered bones were constructed with these cells and seeded onto porous 13-tricalcium phosphate ceramics(13-TCP).Then,the constructs were implanted into left metatarsus defect(21 mm in length)of 8 sheep as an experimental group.Porous ?-TCP composed with bone marrow was implanted into defects of same size and position in 8 sheep as a control group.Sheep were sacrificed in the 6th,12th,and 24th week postoperatively,and the implanted samples were examined by radiograph,histology,and biomechanical analysis.[Result]New bone tissue was observed either radiographically or histologically at the defect area of experimental group as early as the 6th week postoperatively;but was not observed in the control group.Because of the new bone formed in a direct manner without progression through a cartilaginous process intermediately,osteoid tissue,woven bone and lamellar bone,occurred earlier in the experimental group than in the control group,in which the bone defects were repaired in a "creep substitution" manner.At the 24th week,radiographs and biomechanical tests revealed an almost complete repair of the defect in experimental group,but only a partial repair in the control group.[Conclusion]MSCs have good reproductive activity not only in vitro,but also in vivo.The new bone formed in a direct manner without progression through a cartilaginous process intermediately when MSCs were transplanted in vivo.The results demonstrated that MSCs was an excellent seed cells for bone tissue engineering.

Objective To analyze the reasons of the common complications happened after the operation of congenital syndactyly and to find the method of prophylaxis and treatment,and to improve the effects of treatment.Methods To classify the reasons of the complications happened after the operation of congenital syndactyly in 34 cases.Results The reasons of the complications included that the patients were not operated by special course of study doctors in 9; operation at an inappropriate opportunity in 8;the method of web taken shape was improper in 7;the method of nail taken shape was improper in 4; the fixation and training was unsuitable in 6.

Objective To analyze drug resistance data of Enterococcus faecalis and Enterococcus faecium,submitted by member units of Chongqing bacterial drug resistance monitoring network,and to provide the basis for our city effective application of antimicrobial agents and the reference.Methods Target bacteria identification and drug susceptibility test were performed by member units,according to the national technology scheme of bacterial drug resistance monitoring network and the results were determined according to standards published by Clinic and Laboratory Standard Institute(CLSI) in 2015.WHONET5.6 software was used to analyze drug susceptibility,and drug resistance difference was analyzed by using SPSS21.0 software.Results A total of un-repeated 1 811 strains of Enterococcus faecalis and 1 601 strains of Enterococcus faecium,accounting for 13.1% of all positive strains.The resistant rates of the two kinds of bacteria to vancomycin were 0.5% and 1.8%,to rinathiazole amine were 2.5% and 0.5% respectively.Tigecycline resistant strains were not founded.The resistant rate of Enterococcus feaclis to ouinupristin/dalfopristin was 90.1%,to tetracycline was 78.8%,to high concentration of gentamicin was 43.0%,to penicillin,ampicillin and nitrofurantoin was less than 7%.Except ouinupristin/dalfopristin and tetracycline,the resistant rate of Enterococcus faecium to the other drugs were significantly higher than Enterococcus faecalis(P<0.05).Strains isolated from children and adult patients,Intensive Care Unit(ICU) and un-ICU patients were with differences of drug resistance(P<0.05).Conclusion Most of Enterococcus infection could be caused by Enterococcus faecalis and Enterococcus faecium.Monitoring of drug resistance might be helpful for rational and effective usage of antimicrobial agents.
