Acute suppurative thyroiditis (AST) is a rare non-specific infectious disease of thyroid gland.The signs and symptoms of AST may mimic those of a variety of noninfectious inflammatory conditions or other anterior neck infectious diseases.AST is a progressive disease and is also potentially life threatening if devoid of prompt diagnosis and proper treatment.Herein,we report a case in order to call attention to the diagnosis and treatment of AST.

BACKGROUND: As a primary clinical predictor of fracture risk, bone mineral density (BMD) is partly genetically determined. Osteoprotegerin (OPG) is one important candidate gene in the pathogenesis of osteoporosis. OBJECTIVE: To investigate the association between T245G polymorphisms in the OPG gene and BMD. METHODS: A total of 281 elderly men and postmenopausal women, 182 males and 99 females, who received routine examinations at Peking University People's Hospital between September 2008 and April 2010 were included in this study. T245G polymorphisms in the OPG gene was detected by polymerase chain reaction-restriction fragment length polymorphism together with DNA sequencing. The BMD of the lumbar spine, Ward's triangle, and forearrm was determined by dual energy X-ray absorptiometry. Clinical variables and biochemical measurements were collected simultaneously. The association between T245G polymorphisms and each detection index was analyzed using analysis of variance. RESULTS AND CONCLUSION: The distribution of T245G genotype (alleles T, G) had no difference in elderly men or postmenopausal women (P > 0.05). The GG genotype and TG genotype had higher lumbar spine BMD and TT genotype had lower lumbar spine BMD (P < 0.05). There was no difference in BMD of the Ward's triangle or forearm among different genotypes (P > 0.05). Association between T245G polymorphism and BMD was not found in postmenopausal women. These findings indicate that OPG gene is related to lumbar spine BMD in elderly men.

Objective To study the clinical effect of the BacFuse for the lumbar disc herniation(LDH) and to discuss the affect for symptom of patients and structure of spine.Methods Collected the patients suffered from LDH retrospectively who had been implanted the BacFuse.There were 25 patients (29 surgical levels) included in the study.The clinical and X-ray assessment have been done on preoperation,postoperation,3 month,6 month and 12 month.Clinical index used visual analogue scale (VAS) score,oswestry disability index (ODI) score and Japanese Orthopaedic Association (JOA) score assessed clinical symptom and physical function.The intervertebral angle,posterior disk height and foraminal height were measured in X-ray.The patients were taken CT at preoperation and postoperation.The area and distance of herniated disc were measured in CT scan.Results In the aspect of clinical effect,25 cases were finished operation successly.The VAS score decreased from (6.61±1.29) points on preoperation to (2.78±1.00) points on the last follow-up,the ODI score decreased from (31.9±8.3) points to (15.9±6.4) points,the JOA score increased from (9.6± 3.0) points to (18.8± 3.2) points.In the aspect of spine structure,the intervertebral angle decreased from 10.1°±5.4° on preoperation to 8.4°±4.9° on the last follow-up,the posterior disk height increased from (0.65±0.29) cm on preoperation to (0.78±0.27) cm on the last follow-up and the foraminal height increased from (2.01±0.35) cm on preoperation to (2.16±0.37)cm.There was significant difference on posterior disk height and foraminal height between preoperation and postoperation,while the posterior disk height lost (0.07±0.12) cm (9.3％) and foraminal height lost (0.06±0.19) cm (2.7％).The CT showed that area of herniated disc decreased from (4.10±0.78) mm to (3.72±0.66) mm (9.3％) and distance of herniated disc decreased from (96.4±37.8) mm2 to (83.8±31.1) mm2 (7.4％).Conclusion BacFuse can relieve symptom and affect the biomechanics of the spine,makes the herniated disc retract partially,playing a Internal Retractor role in spine,and it is a new effective therapy for LDH.

BACKGROUND:The emergence of a large number of hidden blood loss during perioperative period of intertrochanteric fracture in the elderly not only increases the risk of perioperative period and complications, but also affects the postoperative recovery of joint function. At present, there is no relevant report about nutritional status and the hidden blood loss before surgery in and outside China.
OBJECTIVE:To identify the effect of nutritional status on preoperative hidden blood loss in elderly patients with intertrochanteric fracture.
METHODS:183 elderly patients with fresh and initial femoral intertrochanteric fracture were included. Laboratory serological examinations on admission and preoperation were completed. By mini nutritional assessment, patients were randomly divided into normal-nourishment group, malnourishment at risk group, and malnourishment group. The original blood volume and preoperative hidden blood loss were calculated depending on height, weight, hematocrit on admission and preoperation. According to the proportion of mean preoperative hidden blood loss on the original blood volume, patients were divided into low and high hidden blood loss groups. We compared preoperative hidden blood loss, and their proportion on the original blood volume and the preoperative incidence of high hidden blood loss, and analyzed the correlations between preoperative high hidden blood loss and preoperative nutritional status.
RESULTS AND CONCLUSION:(1) The nutritional status of elderly intertrochanteric fracture patients measured by mini nutritional assessment score was that the number of patients was 48 cases (26%) in normal-nourishment group, 64 cases (35%) in the malnourishment at risk group, and 71 cases (39%) in the malnourishment group. There were no obvious differences in the preoperative complications between any two groups (P>0.05). (2) Thirty-eight cases affected high hidden blood loss. The mean preoperative hidden blood loss was 260.43 mL. The proportion of preoperative hidden blood loss to the original blood volume was 6%. (3) The preoperative hidden blood loss, their proportion on the original blood volume and the incidence of high hidden blood loss were significantly higher in the malnourishment at risk group and malnourishment group than in the normal-nourishment group. Paired comparison showed significant differences (P<0.05). (4) Results confirmed that preoperative hidden blood loss, their proportion on the original blood volume and the incidence of high hidden blood loss gradual y increased with deterioration of nutritional status. The nutritional status is an important factor influencing the occurrence of preoperative hidden blood loss, and can be used as an important index for judging the high hidden blood loss and prognosis in elderly patients with intertrochanteric fracture.

BACKGROUND:Results of recent studies demonstrated the modulation of thymosin β4 on hair cycle and regeneration, but the mechanism of action remains unclear.
OBJECTIVE:To investigate the mechanism by which thymosinβ4 increases hair regeneration through Wnt signal pathway.
METHODS:After the mouse model of depilation was established using rosin/paraffin mixed agents, the experimental animals were randomly assorted to three different groups, including low-dose, high-dose and control groups, and a dose of 0.3μg/50μL, 3μg/50μL thymosinβ4 and PBS was administered on the depilated backs every 12 hours, respectively. Then photography, hematoxylin-eosin staining, immunohistochemistry and in situ hybridization were applied to observe the growth of hair, and the expressions ofβ-catenin and LEF-1 mRNA in different groups at different time were quantitatively evaluated.
RESULTS AND CONCLUSION:The hair growth of the low-dose group was faster than that of the other groups. Hematoxylin-eosin staining demonstrated inflammatory cel s infiltration in the dermis after depilation, and the number of hair fol icles that were in the phase of anagen was much more than the other groups as time went by. Immunohistochemistry ofβ-catenin showed the accumulation of intra-cel ularβ-catenin in the low-dose group at the bulge of fol icles assessed by integrated absorbance analysis (P<0.05), so did the in situ hybridization of LEF-1 mRNA. Low-dose thymosinβ4 accelerates hair growth through Wnt signal pathway by elevating the level ofβ-catenin and LEF-1 mRNA.
