RESUMO
Extraskeletal Ewing sarcoma is a rare event, and extraskeletal Ewing sarcoma of the thyroid gland is even rarer. It has non-specific clinical manifestation and difficulty in early diagnosis. The diagnosis mainly depends on histology and immunohistochemistry. It possesses the features of high malignancy, high rate of local recurrence, and distant metastasis. Currently, the aggressive multimodal treatment contains surgery, chemotherapy, and radiotherapy. This study presented a case of extraskeletal Ewing sarcoma arising in the thyroid gland of a 30-year-old woman, who presented with supraclavicular mass and sense of dysphagia obstruction in Department of Otolaryngology, Head and Neck Surgery, Second Xiangya Hospital, Central South University in 2018. Imaging studies demonstrated a cystic-solid mass in inferior of the left leaf of thyroid gland and in the posterior of the trachea and esophagus. The patient underwent localized tumor resection. The pathological diagnosis revealed that it was a small round cell tumor, and the immunohistochemistry results were considered to be extraskeletal Ewing sarcoma. Subsequently, the patient was given chemotherapy and local radiation therapy. There was no evidence of tumor recurrence or metastasis.

Objective:To investigate the effects of posterior condylar offset (PCO) change on functional recovery after high-flexion posterior-stabilized total knee arthroplasty (TKA).Methods:From December 2018 to May 2019, a total of 76 patients (7 males and 69 females) who underwent primary TKA were included. The age of patients was 67.78±5.13 years (56-75 years). Preoperative and postoperative radiological PCO were measured by lateral knee X-ray. The true preoperative PCO was defined as the sum of radiological PCO and the thickness of posterior condylar cartilage. According to the changing of PCO (ture preoperative PCO - postoperative PCO), the subjects were divided into four groups, namely 28 cases in ≤-3 mm group, 23 cases in -3 mm- group, 15 cases in 0 mm- group and 10 cases in ≥3 mm group. The parameters, including age, body mass index, range of motion (ROM), Knee Society Scores (KSS) and visual analogue score (VAS) before the operation, were not significantly different among four groups. ROM, KSS, VAS at 2 weeks, 1 month, 3 months, 6 months after the operation were compared among the four groups.Results:There were good inter-observer reliabilities regarding the parameters measured in this study ( ICC>0.75). The KSS, ROM, VAS of all the subjects after operation were significantly better than those before the operation ( F=318.768, 64.983, 361.749; P=0.000). In all groups, the recovery of KSS and VAS last to 6 months after the operation. The ROM trended to be stable at the 3 months after the operation. At 6 months after operation, ROM, KSS and VAS of ≤-3 mm group was 116.07°±9.66°, 156.25±21.49, and 1.18±0.94, respectively. These parameters of -3 mm- group was 119.57°±7.52°, 162.17±17.09, and 1.26±0.86. However, these parameters of 0 mm- group was 126.07°±5.25°, 161.86±8.86, 1.00±0.55, respectively. These of ≥3 mm group was 118.00°±4.21°, 156.60±16.98 and 1.30±0.95. The KSS, KSS anatomy score, KSS function score and VAS were not significantly different at any follow-up point among four groups. The ROM of 0 mm- group at 1 month, 3 months and 6 months after operation (118.57°±13.07°, 25.00°±6.20°, 126.07°±5.25°) was significantly different from other three groups ( F=4.966, P=0.003; F=4.179, P=0.006; F=5.262, P=0.003), while 0 mm- group's ROM were greater than other three groups ( P<0.05). Conclusion:Increasing within 3 mm of PCO was related to larger postoperative ROM in high-flexion posterior-stabilized TKA. However, change of PCO had no influence on the outcomes of KSS recovery and pain relief.
RESUMO
Through analysis and summary of the biological characteristics of various biomarkers,to explore the reliability of different markers for early diagnosis of osteoarthritis.Cartilage oligomeric matrix protein,Nterminal crosslinked telopeptide of type [collagen and C-terminal crosslinked telopeptide of type Ⅱ collagen are the possible effective markers in osteoarthritis early diagnosis.Hyaluronic acid and C-terminal crosslinked telopeptide of type Ⅰ collagen are more suitable for evaluating the ollurrence and derelopment of osteoarthritis.The efficacy of miRNA and IncRNA in osteoarthritis diagnosis and evaluation remains to be proved.Each marker may has two or more biological effect,this paper will focus on finding out an accurate and stable marker with the analysis and summmary of present bio-markers.

Cartilage oligomeric matrix protein, N-terminal crosslinked telopeptide of type Ⅰ collagen and C-terminal crosslinked telopeptide of type Ⅱ collagen are the possible effective markers in osteoarthritis early diagnosis. Hyaluronic acid and C-terminal crosslinked telopeptide of type I collagen are more suitable for evaluating the ollurrence and derelopment of osteoarthritis. The efficacy of miRNA and lncRNA in osteoarthritis diagnosis and evaluation remains to be proved. Each marker may has two or more biological effect, this paper will focus on finding out an accurate and stable marker with the analysis and summary of present bio-markers.
RESUMO
Informatization has brought opportunities to the development of the medical industry, human resource management in hospital of traditional Chinese medicine. The management of human resources in the hospital of traditional Chinese medicine should adopt new ideas and system, and change the traditional human resource management mode. Through studying the status of human resource information management in hospital of traditional Chinese medicine, the relevant measures and suggestions for the construction of human resource information management system in hospital of traditional Chinese medicine are put forward in this paper.
