Objective To investigate the clinicopathological features of glomus tumor and its differential diagnosis. Methods Clinical, morphologie and immunohistoehemical representations were described in 11 cases of glomus tumor. Results The tumors were located at the hyponychial in 7 cases, forearm subcutaneous in 2 cases, knee subcutaneous in 1 case, gastric antrum forewall in 1 cases. Localized pain was the primary symptom. 9 giomus tumors were histopathologically classified as solid type, and 2 glomangiomatous type. The prominent morphologic features of glomus tumor were as follows: the tumor cells were small, round, uniform, the tumor cells arranged around capillary vessel or expansion of the small vein showing nest pattern,some tumor cells in fasciation pattern; focally myxoid change in the stroma were seen. Immunohistochemistry: 11 cases were positive for SMA and Vimentin; while other markers including CK, CD117, CD34, CgA, Syn, Desmin, S-100 and HMB45, were all negative. All 11 cases were without any evidence of recurrence or metastasis in followed-up for 12-30 months. Conclusion Glomus tumor is extremely rare. The diagnosis depends on the histology and immunohistochemistry. Glomus tumor is rare in visceral sites. It may be misdiagnosed and needs to he differentiated from other tumors.

Objective:
To evaluate the daily average intake of dietary fiber of primary school students in Gongshu District, Hangzhou, in order to strengthen the diet guidance and health education.
Methods:
The method of stratified random cluster sampling was employed to carry out a dietary survey for 887 pupils from 2-6th grade selected from 4 primary schools in Gongshu District, Hangzhou City. The consumption of various kinds of breakfast in pupils’ diet was obtained through dietary survey. The content of dietary fibers in various kinds of food was determined by enzymatic-gravimetric method, and based on this, the daily average intake of dietary fiber of pupils in Gongshu District was calculated.
Results:
A total of 434 samples of 12 kinds of food in Gongshu District of Hangzhou were determined. The results showed that the dietary fiber content ranged from 0.31 to 2.17 g/100 g in all kinds of breakfast. The difference of dietary fiber content was statistically significant(F=76.50, P=0.00). Among them, noodles and soybean milk were found of more dietary fiber content. However, pupils’ dietary fiber intake for breakfast ranged from 1.82 to 3.04 g/100 g, and the intake was generally low, showing an increasing trend with the increase of grade. The difference of dietary fiber intake among the second to sixth grades was statistically significant (F=18.72, P=0.01). After comparison by SLD method, it was found that the difference of dietary fiber intake between the second and third grade (P=0.22), and between the fifth and sixth grade(P=0.30) were not statistically significant, but the others were statistically significant(P<0.05).
Conclusion
The unreasonable dietary structure and poor breakfast quality are common phenomena. Well-tailored education programs slaping of adequate and blanced dietary behaviors are in great needs.

Background and objective A solitary pulmonary nodule (SPN) is deifned as a round intraparenchimal lung lesion less than 3 cm in size, not associated with atelectasis or adenopathy. hTe aim of this study is to learn clinical experi-ence of the treatment of SPN with Da Vinci Surgical System. Methods A total of 9 patients with solitary pulmonary nodules (SPN) less than 3 cm in diameter was treated with Da Vinci Surgical System (Intuitive Surgical, California) in thoracic surgery department from General Hospital of Shenyang Militrary Region from November 2011 to March 2014. hTis group of patients included 3 males and 6 females, and the mean age was 51±9.9 yr (range:41-74 yr). Most of the patients were no obvious clini-cal symptoms (7 cases were found by physical examination, others were with cough and expectoration). hTeir median medical history was 12 mo (range:4 d-3 yr). All the lesions of patients were peripheral pulmonary nodules and the mean diameter of those was (1.4±0.6) cm(range:0.8-2.8 cm). Wedge-shaped resection or lobectomy was performed depending on the result of rapid pathology and systemic lymph node dissection was done for malignant leision. We used general anesthesis with double lumens trachea cannula. We set the patients in lateral decubitus position with jackknife. hTe patient cart enter from top of the patient. hTe position of trocars would be set according to the position of lesion. A 12 mm incision was positioned at the 8th intercostal space in the posterior axillary line as vision port, and two 8 mm incisions were positioned at the 5th intercostal space between the anterior axillary line and midclavicular line, and the 8th infrascapular line as robotic instrument ports about 10 cm apart from the vision port. One additional auxiliary small incision for instrument without retracting ribs was set at the 7th in-tercostal space in the middle axillary line. Results hTere were 4 benign leisions and 5 malignancies identiifed. Wedge-shaped resection was performed for 4 patients, lobectomy with systemic lymph node dissection for 3 patients (including 2 right middle lobectomies and 1 letf upper lobectomy) and wedge-shaped resection with systemic lymph node dissection for 2 patients of poor lung function. All of the 9 cases were completed with total robotic procedure without conversion. hTe pathological results included 3 inlfammatory pseudotumors, 1 hamartoma, 5 adenocarcinomas. All of the 29 patients were hospital discharged smoothly. hTe patients were followed up for 0.1-18.5 mo (median 11 mo) without recurrence or metastasis. Conclusion hTe SPN patients should be given active surgical treatments to improve the diagnose rate as well as the cure rate of early non-small cell lung cancer. Since da Vinci Surgical System is a safe and minimally invasive treatment for SPN, it has higher value to the diagnosis and treatment of SPN.

Background and objectivePostoperative radiotherapy (PORT) for thymic tumor is still controversial. The object of the study is to evaluate the role of PORT for stage I/II/III thymic tumor.MethodsThe database of Chinese Al-liance of Research for Thymomas (ChART) was retrieved for patients with stage I/II/III thymic tumor who underwent surgi-cal therapy without neoajuvant therapy between 1994 and 2012. Univariate and multivariate survival analyses were performed. Cox proportional hazard model was used to determine the hazard ratio for death.Results 1,546 stage I/II/III patients were identiifed from ChART database. Among these patients, 649 (41.98%) underwent PORT. PORT was associated with gender, histologic type (World Health Organization, WHO), surgical extent, complete resection, Masaoka stage and adjuvant che-motherapy. The 5-yr and 10-yr overall survival (OS) rates and disease-free survival (DFS) rate for patients underwent surgery followed by PORT were 90% and 80%, 81% and 63%, comparing with 96% and 95%, 92% and 90% for patients underwent surgery alone (P=0.001,P<0.001) respectively. In univariate analysis, age, histologic type (WHO), Masaoka stage, complete-ness of resection, and PORT were associated with OS. Multivariable analysis showed that histologic type (WHO)(P=0.001), Masaoka stage (P=0.029) and completeness of resection (P=0.003) were independently prognostic factors of OS. In univari-ate analysis, gender, myasthenia gravis, histologic type (WHO), Masaoka stage, surgical approach, PORT and completeness of resection were associated with DFS. Multivariable analysis showed that histologic type (WHO) (P<0.001), Masaoka stage (P=0.005) and completeness of resection (P=0.006) were independently prognostic factors of DFS. Subgroup analysis showed that patients with incomplete resection underwent PORT achieved the better OS and DFS (P=0.010, 0.017, respectively). However, patients with complete resection underwent PORT had the worse OS and DFS (P<0.001,P<0.001, respectively). ConclusionThe current retrospective study indicated that PORT atfer incomplete resection could improve OS and DFS for patients with stage I/II/III thymic tumor. But for those atfer complete resection, PORT may not help improve prognosis on the whole.
