Objective To explore the relationships of depression status of medical college students with their automatic thoughts and personality. Methods A total of 1 440 medical college students were tested by self-rating depression scale (SDS), automatic thoughts questionnaire (ATQ) and Eysenck personality questionnaire (EPQ). Results ①27.5% medical college students had different degree depressive mood. ② Compared with the non-depression group students, the depression group had higher scores in ATQ, EPQ-N(neurosism) and EPQ-P(psychoticism), lower scores in EPQ-E(extroversion), EPQ-L(lie) (P

Objective:To explore the calvarial critical size defect (CSD)in rats with type 2 diabetes mellitus(T2DM).Methods:T2DM model of SD rats(weighted 300-320 g)was induced by high fat and high sugar diet and low dose intraperitoneal streptozotocin (STZ)injection.The rats with T2DMand the normal controls were divided into 4 groups(n=3)respectively.Defects with the diame-ter(mm)of 2,3,4 and 5 were made on the central calvaria of each rat.General observation,X-ray examination and histological study were performed 8 weeks postoperatively.Results:In the T2DM group,only the defects of 2 mm diameter were healed completely,X-ray resistance and new bone formation were observed;the defects of 3,4 and 5 mm diameter were unhealed,X-ray transmission was observed and newly formed bone was insufficient.In the control group,the defects of 2,3 and 4 mm diameter were healed completely, X-ray resistance and new bone formation were observed;the defects of 5 mm diameter were unhealed,X-ray transmission was ob-served,newly formed bone was insufficient.Conclusion:The calvarial CSD of T2DM rat model can be defined as the defect with the diameter of 3 mm.

Objective To preliminarily verify the effectiveness and safety of bloodletting combined with drug bamboo cups in intervention of degenerative lumbar spinal stenosis,and to explore the prognostic factors that affect the efficacy of TCM regimens in the treatment of DLSS.Methods 64 consecutive patients with degenerative lumbar spinal stenosis were enrolled.Bloodletting combined with drug bamboo cup intervention was used.Acupoints were selected and treated with the same length of the governor channel of the lumbar spine,the first and second side lines of the bladder meridian and Ashi point,weekly 2 times,8 times per course,2 consecutive courses of treatment.Before treatment,after treatment,and 1 month follow-up,the changes of the patient's lumbar spinal stenosis specific scale(SSM),modified Oswestry dysfunction index(ODI),and 12 health survey summary scores(SF-12)were observed.Using SSM symptom or function score≥0.5,the criteria for grouping were first single-factor analysis,and then logistic regression was used to analyze the prognostic factors of the treatment.Results After 2 courses of treatment,the patient's SSM symptom score(2.25±0.56),SSM function score(2.06±0.67),ODI index(15.49±8.72),and SF-12 physiological score(36.31±7.35)were more significant than before treatment Improved,the difference was statistically significant(P<0.05),the SF-12 psychological score(49.70±9.47),the difference was not statistically significant compared with before treatment(P>0.05);the patient's SSM symptom score(2.22±0.54)was followed up for one month,SSM function score(2.09±0.66),ODI index(15.53±8.23),SF-12 physiological score(36.55±7.25),SF-12 psychological score(50.62±9.17),which are significantly better than before treatment,and the difference is statistically significant(P<0.05),the difference was not statistically significant(P>0.05)after 2 courses of treatment.The univariate logistic regression analysis of each influencing factor showed that:BMI,baseline symptom dimension,baseline functional dimension,foraminal stenosis,lateral recess stenosis,and two-stage stenosis had statistically significant differences between the effective and ineffective groups(P<0.05).Conclusion Bloodletting combined with drug bamboo cups has a certain clinical effect on degenerative lumbar spinal stenosis.

The implant prosthesis has been extensively used in clinic recently, and implant failure is appearing. Many factors may cause the failure, and they work together generally. This paper summarizes and analyzes the failure cases related to implant treatment and relevant risk factors of oral implants in Department of Implantation, School of Stomatology, The Fourth Military Medical University during the past six years, in order to improve the success rate of implant prosthesis and provide guidance for clinical application.
