Objective To find out the prevalence of bullying behaviors among urban middle school students in China. Methods An anonymous questionnaire survey was conducted among middle school students selected by multiply stage cluster random sampling in 18 provinces in China. 187 328 self- administration questionnaires were finished by students from grade 7 to 12 in urban middle school(male,86 472; female, 91 106), in which 177 578 were valid. Results Bullying was common in urban middle school students in China. Multiple bullying behavior also existed. About 66.1% of boys and 48.8% of girls suffered from one or more kinds of bullying; 8.1% of boys and 2.9% of girls suffered from four or more kinds of bullying. Boys were more likely to be bullied than girls. Malicious teasing was the most common bullying behavior(43.2%), followed by sexual bullying behavior(27.0%). In addition to malicious teasing and sexual bullying, the prevalence of other types of bullying declined when the grade was increasing. Residential students were more likely to be maliciously teased, excluded or isolated and sexual bullied than non-residential students. Students from single-parent or recomposed-families were more likely to be bullied than other students. Male and ordinary school students, students living with single or step-parents were more likely to suffer multiple bullying behaviors at the same time. Conclusion The suggesting among students was associated with personal, familiar and social factors, mobilize more social forces and comprehensive actions to be taken to prevent bullying among students.

OBJECTIVETo investigate the features and causes of complications of unilateral pedicle screw fixation combined with contralateral percutaneous translaminar facet screw fixation and lumbar interbody fusion in treating lower lumbar diseases.

METHODSThe clinical data of 166 patients with lower lumbar diseases who underwent unilateral pedicle screw fixation combined with contralateral percutaneous translaminar facet screw fixation and lumbar interbody fusion with intervertebral cages from January 2008 to December 2013 were retrospectively analyzed. There were 64 males and 102 females, aged from 24 to 74 years with a mean of 51.9 years old, suffered from lower lumbar lesions for 47.5 months on average (ranged, 8 months to 30 years). Among these patients, lumbar intervertebral disc degeneration was found in 49 patients, recurred lumbar intervertebral disc protrusion in 17 patients, massive lumbar intervertebral disc protrusion in 23 patients, lumbar intervertebral disc protrusion accompany with spinal canal stenosis in 27 patients, lumbar degenerative spondylolisthesis with degree I (Meyerding grade) in 21 patients, far lateral lumbar intervertebral disc protrusion in 5 patients. Single segmental diseases occurred in 124 patients and two segmental diseases in 42 patients. The diseases occurred at L(3,4) segment in 6 patients, at L(4,5) segment in 97 patients, at L5S1 segment in 21 patients, at L(2,3), and L(3,4) segments in 1 patient, at L(3,4) and L4,5) segments in 26 patients, and at L(4,5), and L5S1 segments in 15 patients.

RESULTSThere was no abnormal bleeding in the patients and no patient received blood transfusion. During the surgery, spinal dura mater injury with cerebrospinal fluid leakage complicated in 1 patient, a fracture of vertebral pedicle in 4 patients, and end plate injury in 2 patients. No postoperative cerebrospinal fluid, incision infection and skin necrosis were found after operation. Nerve root injury was found in 1 patient. According to the position of pedicles crew, 371 screws of 163 patients were in degree I and 3 screws of 3 patients were in degree II; position of translaminar facet screw, 199 screws of 157 patients were type I, 8 screws of 8 patients were type II, 1 screw of 1 patient was III. Translaminar facet screw was slightly short in 2 patients. Five patients were lost to follow-up, two patients were died. The remaining patients were followed up for 35.4 months on average (ranged, 12 to 60 months). During the follow-up period , end plate was cut off and intervertebral cages were embedded in 14 segments of 14 patients. Abnormal pain of both lower extremities was found in 1 patient. With the exception of 11 unidentified segments in 11 patients, 189 segments of 148 patients obtained intervertebral fusion. No loosening, displacement, breakage of pedicle screw or translaminar facet screw, displacement of intervertebral cages or obvious degeneration of adjacent segments were found. The coronal and sagittal planes balance of lumbar vertebra were obviously improved. Postoperative JOA score was significantly increased than that of preoperative.

CONCLUSIONUnilateral pedicle screw fixation combined with contralateral percutaneous translaminar facet screw fixation and lumbar interbody fusion with intervertebral cages is a good choice for the treatment of lower lumbar diseases, but it has a risk of complications. Abundant surgeon's surgical experience, careful operation, and rational use of imaging technique can effectively reduce the incidence of complications.

OBJECTIVETo study the correlation of insulin resistance (IR) with TCM syndrome type and activity of fibrinolytic system in patients with coronary arterial disease (CAD).

METHODSOne hundred and twelve CAD patients were classified according to TCM Syndrome into 4 types, the Xin-blood stasis (XBS) type, the phelgm blocking Xin-channel (PBXC) type, the Qi-insufficiency with blood stasis (QIBS) type and the both Qi-Yin deficiency (QYD) type. Patients' fasting blood glucose (FBG), fasting blood insulin (FIns) were measured, the insulin sensitive index (ISI) calculated. Data were compared between various types, also with those obtained from 30 healthy persons in the control group respectively. Moreover, activity of tissue plasminogen activator (t-PA) and content of plasminogen activator inhibitor-1 (PAI-1) were determined in 90 patients selected from the 112 to conduct linear correlation analysis of IR with t-PA activity and PAI-1 content.

RESULTSFBG and FIns levels in the CAD patients were higher than those in the healthy control significantly (P < 0.01); ISI in the 4 syndrome type of CAD patients were all lower than that in the control (P < 0.01). IR existed in all the 4 types, but the level in the XBS type and the PBXC type was more severe than in the other two types. Correlation analysis showed that IR was correlated with t-PA activity and PAI-1 content (P < 0.01).

CONCLUSIONIR often exists in CAD patients, the severity of IR varies in patients of different TCM syndrome types, and IR is correlated with the abnormality of fibrinolytic system activity.
