Nowadays a large number of domestic researches have shown the degree of learning burnout,the causes,manifestations and the distribution,but there are only one or two cases focusing on empirical research of Group Counseling.In Eriksson's view,the university period is a critical stage to obtain a sense of intimacy and avoid isolation,and the group counseling have great significance in helping students improve the character and get a sense of intimacy.Therefore,based on the literature and interviews,the author use in this study the cognitive-behavioral group therapy to help the students form a new cognitive concepts,behavior and attitude,and improve their self-efficacy.

BACKGROUND:The mechanical performance and cytocompatibility of polylactic acid-polyethylene glycol (PLA-PEG) scaffold is poor via long-term experiments; therefore, other materials are added to the scaffold in order to improve its biological activity and mechanical properties. OBJECTIVE:To investigate the preparation process of carbon fiber (CF)-PLA-PEG scaffold, and to test its performance. METHODS:Modified CF-PLA-PEG composite scaffolds were prepared using solution injection-particle leaching method. Ultra-structure, porosity, water-absorbing quality, degradation rate and mechanical properties of CF-PLA-PEG composite scaffolds and PLA-PEG scaffolds were compared. Rat osteoblasts were co-cultured with these two kinds of scaffoldsin vitro, and the cel adhesion rate was detected by precipitation method after 12 hours. Cel counting was detected using MTT method to determine the cel proliferation at culture days 1, 3, 5, 7, 9. RESULTS AND CONCLUSION:The surface structure of PLA-PEG distributed uniformly, and the aperture was (404.0±10.5) μm. The carbon fiber surface of modified CF-PLA-PEG composite scaffolds had a lot of longitudinal grooves, the surface structure also distributed uniformly, and the aperture was (433.0±3.0) μm. Difference in scaffold aperture was of significance between the two groups (P < 0.05). The porosity, water-absorbing quality, elasticity modulus, compressive strength, degradation rate, cel adhesion rate and cel growth rate of CF-PLA-PEG were better than those of PLA-PEG (P < 0.05). These results show that the CF-PLA-PEG scaffolds have good mechanical property and cel compatibility.

Patients in the group A were treated by dinoprostone suppositoriesository, patients in the group B were treated by oxytocin, patients in the group C were treated by the cervical dilation balloon, the cervical, childbirth, complications and newborns in the 3 groups were observed and compared. Results Compared with group B and group C, late pregnancy induced labor curative effect in group A was better:cervical Bishop score was higher after intervention 6h and 12 h (P<0.05), and promote cervical mature rate and success rate of induced labor were higher(P<0.05), labor time was shorter (P<0.05).The incidence of delivery complications was lower(P<0.05).Conclusion Dinoprostone suppositories can reduce labor time significantly in the treatment of late pregnancy, and improve the success rate of induced labor, the effect is superior to oxytocin and cervical dilation balloon.

[ABSTRACT]OBJECTIVE To summarize the clinical related factors and prognostic influence factors of perioperative pulmonary embolism of head and neck malignant tumor.METHODSFrom 2010-2014, our hospital carried out a total of 2736 cases of head and neck malignant tumor surgical operations, of which, 10 cases were clinically diagnosed as postoperative pulmonary embolism, retrospectively analyzed the process of clinical treatment of the patients of pulmonary embolism with head and neck malignant tumors, and summarized their etiological factors, clinical manifestations, diagnosis and treatment. RESULTS The preoperative period incidence of pulmonary embolism in patients with head and neck malignant tumor was 0.37%(10/2736). Their clinical manifestations were mainly of asthma and breathing difficulty, and 3 cases of asymptomatic hypoxemia. 8 cases of patients showed pulmonary artery and branch filling defects after pulmonary artery angiography (CTA), 7 cases of patients got cured and were discharged from the hospital after comprehensive treatment such as anticoagulation etc; 3 cases of patients died after emergency treatment. 2 cases of patients suffered cavity bleeding, and there was no anticoagulant drug adjustment.CONCLUSIONThe mortality of head and neck cancer patients with perioperative pulmonary embolism is high, and therefore, preventive measures and timely treatments are important to reduce the incidence of pulmonary embolism.

Objective To assess the diagnostic value of chronotropic index in identifying coronary artery disease (CAD). Methods One hundred and sixty two patients with suspected CAD were referred for a routine treadmill exercise electrocardiogram and subsequently underwent selective coronary angiography within 3 weeks. The magnitude of ST segment depression and chronotropic index were measured by a computerized ECG system. CAD was defined by coronary angiography. Results In detecting CAD, the sensitivity was 70. 1% versus 60.9% (P< 0.05) ,the specificity was 84.0% versus 73.3% (P<0.05), and the accuracy was 76.5% versus 66.7% (P< 0.05) by chronotropic index and standard electrocardiographic test criteria. The value of Kappa statistic for chrono-tropic index consistency in our experiment was 0.534(>0.4). The number of diseased vessels was correlated with the mean value of chronotropic index. The chronotropic index decreased from 0.88±0.09 in patients without coro-nary disease to 0.68±0.06 in those with 3 vessels involved (P<0.01). A more closed relationship was found be-tween chronotropic index and lesion in the fight coronary artery. Conclusions Chronotropic index is possibly a valu-able positive index for the diagnosis of CAD. The sensitivity,specificity and accuracy of chronotropic index are signif-icandy higher than those of standard electrocardiographic test criteria in identifying CAD.

BACKGROUND: As a kind of filling material for wedge-shaped defects, GC Fuji Ⅸ glass-ionomer cement has arose more and more attention. However, the comparison of repair results between GC Fuji Ⅸ glass-ionomer cement and reinforced glass-ionomer cement are poorly understood. OBJECTIVE: To compare the clinical effect of GC Fuji Ⅸ glass-ionomer cement and reinforced gtass-ionomer cement for repairing wedge-shaped defects of old people. METHODS: Totally 80 teeth were randomly divided into 2 groups, and filled by GC Fuji Ⅸ glass-ionomer cement (experimental group) and reinforced glass-ionomer cement (control group), respectively. The clinical effect of 2 materials were evaluated on color match, edge density heterozygosity, restoration integrity, occurrence of secondary caries and pulp symptom at immediately, 3 months, 6 months and 1 year after placement. RESULTS AND CONCLUSION: The color match of the experimental group was better than that of the control group at 3 months, 6 months and 1 year after placement (P < 0.05); and the edge density heterozygosity of the experimental group was superior to the control group at 6 months and 1 year after placement (P < 0.05); in addition, the restoration integrity of the experimental group was surpass the control group at 1 year after placement (P < 0.05). It demonstrated that GC Fuji IX glass-ionomer cement is an ideal choice for wedge-shaped defects of old people, which exhibits superior effects to reinforced glass-ionomer cement in 1-year follow-up.

Conclusions TLR4 and CTLA-4 were high expression in hypertensive patients with hypertension,and related to hypertension.

Objective: To study the impression of Chinese people on Chinese urban children, their main source of information about the Chinese people, and the infvuence of age, school, and gender upon their evaluation. Methods: 383 Chinese urban children ranging from 5 to 12 years were interviewed individually or investigated with the questionnaire. Results: Most of the children reported that the Chinese were happy, clean, peaceful, clever, hardworking, kind and nice. However, the urban children's positive impression of the Chinese people was decreased with their growing up. The study also found that children's information on the Chinese people was mainly in order from television, newspapers, books and cartoons, parents, classmates, friends and teachers, and radio, and that the information source became increasingly diversificed with age. No significant difference in gender and between two schools was found. Conclusion: Chinese urban children had a positive impression of Chinese people, and they had a preference and identity for Chinese people . Mass media were the main source of information.

Objective To study the relationship between expression of leptin and clinical pathogenesis and prognosis of stage Ⅱ colorectal cancer.Methods The clinical data of 102 patients with colorectal cancer admitted to Shaanxi Provincial Tumor Hospital between January 2005 and December 2010 was collected and statistically analyzed.The expression of leptin in postoperative colorectal cancer tissues and 40 normal colorectal tissues was detected by P-V immunohistochemical technique.Results The expression of leptin in cancer tissues were obviously higher than that in normal tissues [59.8 ％ (61/102) vs.17.5 ％ (7/40),x 2 =20.605,P =0.000].There was no association between leptin expression level and gender,age,tumor location,pathological grading,pathological types,tumor size,invasion depth and body mass index (all P ＜ 0.05).Cox multivariate regression analysis showed that leptin expression (P =0.041) and adjuvant chemotherapy (P =0.008) were independent factors affecting OS in patients with stage Ⅱ colorectal cancer.The patients with positive expression of leptin could not benefit from the adjuvant chemotherapy (P =0.259),and patients without leptin expression had improved survival when treated by adjuvant chemotherapy (P =0.021).Conclusion The expression of leptin in stage Ⅱ colorectal cancer tissues is obviously higher than that in normal tissues.Leptin is associated with chemotherapy resistance and therapy-independent prognosis.
