Objective To discuss the appropriate excision area of the thyroid microcacinoma. Methods 46 patients with thyroid microcarcinoma confirmed by pathology result were analyzed, in which 28 patients under-went thyroid lobectomy of lesion side and subtotal lobectomy of the other;8 patients were treated with subtotal lo-bectomy of both side;3 patients were treated with lobectomy of one side and partial resection of the other, while the rest 7 patients underwent the surgery of lesion side lobectomy and neck dissection plus subtotal lobectomy of the other side. Results No complicaitons were observed. All patients were follow-uped for 1 ～ 5 years. 2 patients were disgnosed as recurrance 3 years and 4 years after the operation respectively. The rest survived without recur-rance. Conclusions The appropriate surgery approach for thyroid microcacinoma might be lesion side lobectomy and subtotal lobectomy of the other side.

Objective To explore undergraduate nursing students’psychological feelings during the internship, and provide a theoretical basis for the development of clinical nursing teaching measures. Methods The phenomenological research methods in qualitative study were adopted in this paper and 15 undergraduate nursing students were done with unstructured interview. In order to extract the theme, the obtained information were analyzed and organized with phenomenological analysis. Results Using the generic analytical method we got four topics about psychological feeling that influenced undergraduate nursing students. The low professional identity, mental depression, limited capacity cannot meet the needs of patients and the teacher was too busy to care of undergraduate nursing students that influence the practice enthusiasm. Conclusion The care managers and teachers should take various measures to improve the quality of nursing students and their theoretical and technical skills, develop a reasonable plan to improve the mental health status of undergraduate nursing students and the quality of clinical nursing practice can be improved.

Objective To investigate the value of intraoperative neuromonitoring(IONM) for preventing recurrent laryngeal nerve(RLN) injury in thyroid surgery.Methods 1087 consecutive patients undergoing thyroid surgery at Wuhan Central Hospital from Oct 2010 to Dec 2012 were evaluated.277 cases(the study group) underwent thyroidectomy with RLN identification by naked eye plus IONM.810 cases(the control group)underwent thyroidectomy with RLN identification by naked eye only.Results In the control group,733 RLNs (90.49％,733/810)were successfully identified and 77 RLNs were failed to be identified.In the study group,all the 277 RLNs(100％,277/277)were successfully identified.28 cases had postoperative temporal RLN injury,among whom 26 cases were in the control group and 2 cases were in the study group.18 cases in the control group and 2 cases in the study group recovered in 2 weeks after surgery.The rest recovered in 2 months after surgery.RLN injury rate was significantly lower in the study group than in the control group.There was no significant difference in RLN injury for low-risk surgical patients between the 2 groups; however,the study group had advantages in RLN injury than the control group for high-risk patients.Conclusions IONM in thyroid surgery can improve the recognition rate of RLN during thyroidectomy.IONM can significantly reduce the incidence of RLN injury,especially in high-risk surgery.

AIM: To investigate the influence of dialysate on the cell morphology and the peritoneal membrane function in chronic peritoneal dialysis rats. METHODS: 40 SD rats were divided randomly into 4 groups. Except control group, other groups daily received infusion of 20 mL dialysate (4.25% dialysate(HG), 1.50% dialysate(LG), Riger's solution(RG)) respectively for 8 weeks. The peritoneal membrane function was investigated by peritoneal transport test, and the rat peritoneal mesothelial cells(PMCs)morphology was analyzed by the cell imprints. RESULTS: The intraperitoneal volume and net ultrafiltration in HG and LG groups were significantly lower, with D/P_(urea) significantly higher, and C_(urea) after 4 h of dialysis significantly lower than that in RG and control groups. The density of cell population from analysis of cell imprints in HG and LG groups was significantly lower, but the mean surface area were significantly larger than that in RG and control groups. These change had no difference between HG and LG group. Using the high glucose dialysate for 8 weeks significantly decreased the ultrafiltration volume ,which was significantly relate to the increasing of cell surface area (r=-0.896,P

Objective To explore the effects of parent-adolescent conflict and cohesion on relational aggression among junior students.Methods Parent-adolescent Conflict Questionnaires,Parent-adolescent Cohesion Questionnaires,and the Relational Aggression Questionnaires were used in investigating 392 junior students.Results The level of relational aggression of junior students was low (22.52±5.15).There was no differences between relational aggression of male students (22.93± 5.43) and female students (22.00± 4.73) (P＞ 0.05),and of grade 1 students(22.72±5.14)and grade 2 students(22.64±5.67),grade 3 students(21.93±4.22) (P＞0.05).The students' relational aggression showed a significantly positive correlation with frequency and intensity of parent-adolescent conflict(r=0.269,r=0.307,r=0.268,r=0.271,P＜0.01),and negative correlation with father-adolescent cohesion(r=-0.171,P＜0.01).Parent-adolescent cohesion was negative predictor of relational aggression(β=-0.123,P＜0.05),and the intensity of parent-adolescent conflict was positive predictor(β=0.301,P＜0.01).Conclusion Parent-adolescent conflict and cohesion have significant effect on relational aggression among junior students.

Objective To explore the association of suprapatellar pouch effusion with knee pain and serum levels of interleukin (IL)-6,IL-17,IL-23 in patients with knee osteoarthritis measured by magnetic resonance imaging (MRI).Methods 204 patients with knee osteoarthritis were enrolled into the study.Suprapatellar pouch effusion was measured by OSIRIS in both grade (0-3) and maximum area (cm2).Serum IL-6,IL-17,IL-23 were measured.Knee pain was assessed by Western Ontario and McMasters osteoarthritis index (WOMAC) questionnaire and Lequesne index.Characteristics of patients were recorded and body mass index (BMI) was calculated.Student t test or Chi-square test was used to compare means or proportions.Multivariable linear regression or logistic regression was used to determine risk factors (α=0.05).Results ① In the 204 patients [mean age (55±8) years,86.3％ were females],the prevalence of physiologic effusion (≤ 1) was 47.9％ while moderate or larger (≥2) effusion was 52.1％.② The age,labour intensity,serum levels of uric acid (sUA) and Lequesne index of higher grade effusion group were higher (P＜0.05) compared with lower grade effusion group.③ Suprapatellar pouch effusion maximum area was positively correlated with age (r=0.208,P=0.006),BMI (r=0.171,P=0.027) and labour intensity (r=0.189,P=0.013).④ Adjusted for age,gender and BMI,the results of Logistic regression analysis showed that:suprapatellar pouch effusion grades were positively correlated with Lequesne index [OR=1.120,95％CI(1.011,1.241),P=0.029] and negatively correlated with IL-23 [OR=0.768,95％CI (0.598,0.986),P=0.038].Suprapatellar pouch effusion was not independently associated with WOMAC index,IL-6 and IL-17.Conclusion The prevalence of suprapatellar pouch pathological effusion is 52.1％ in knee osteoarthritis.Suprapatellar pouch effusions is positively correlated with knee pain (Lequesne index) and negatively conrelated with IL-23.
