The rashness in research as reflected in the initial misidentification of the pathogen of SARS is of great enlightening and warning significance to scientific and technical workers in the medical field. In order to effec-tively reduce errors in the clinical diagnosis of SARS, succeed in obtaining reliable methods for its specific diagnosis, and strive for a genuine victory in the fight against it, it is imperative to vigorously uphold the scientific spirit of adher-ing to truths and defying authorities and promote the style of doing things in a rigorous, realistic, accurate, persistent and down-to-earth manner. Rashness must be avoided by all means.

BACKGROUND:Open reduction is general y not advocated for the treatment of children clavicle fracture, because the thick and tough periosteum remains intact and attached by the ligament attachment. In clinic, twin-ring external fixation and simple suspension are commonly used, but there is no reliable basis on which method can get better effect.
OBJECTIVE:To compare the stability of twin-ring external fixation and simple suspension for the treatment of children clavicle fracture.
METHODS:The patients with children clavicle fracture and treated by twin-ring external fixation and simple suspension were selected from June 2008 to December 2012, including 17 patients treated with simple suspension and 22 patients treated with twin-ring external fixation. The X-ray film examination was performed regularly to observe the fracture healing and shoulder function.
RESULTS AND CONCLUSION:The 17 patients treated with simple suspension had good healing;three cases had gap between fracture ends at 1 week after treatment, and re-suspension to increase the height and final y two fracture ends contacted in one case;for the other two cases, there was stil gap between fracture ends, and changed for twin-ring external fixation, the fracture ends contacted. Al the 22 patients in the twin-ring external fixation group obtained healing;five cases had performance of upper extremity neurovascular compression on the fracture side after fixation;after releasing, three cases had recovery, and two cases were treated with simple suspension, the fracture ends began to contact;six cases had armpit redness;four cases had early sleep difficulties;two cases had gap between fracture ends at 1 week after treatment, and after re-adjust, the fracture ends contacted in two cases. The results showed both two methods could not cause appearance deformity, and both could get healing. The simple suspension fixation is easy to operate with reliable effect, and it is comfortable which make it easy to accept by the children, it has the advantages of early for functional exercise, less tissue damage, does not affect the blood supply;the twin-ring external fixation is easy to compress the axil ary arteries and nerves on both sides, thus resulting in upper extremity swel ing, numbness and skin redness, and it can cause discomfort night sleeping and poor comfort which is not easy for children to accept. But, no matter what method we take, the review after 1 week, as wel as the line between proximal and distal part and the contact between fracture ends is stil important.

An intensive practice scheme,integrating clinical practicing education with continuing medieal education after graduation was introduced to Provide a new mode of teaching activities and management of clinical practice.

Objective To observe the clinical efficacy of Dong’s Pushing Epiglottis Cartilage Method for the treatment of children food retention through randomized, parallel and controlled clinical trial.Methods Totally 72 children diagnosed with children food retention were randomly divided into treatment group and control group, 36 cases for each group. Children of the treatment group were treated with Dong’s Pushing Epiglottis Cartilage Method, while children of the control group were treated with acupuncture Four Seam. The clinical symptoms, gastric half-emptying time and antral contraction frequency of the two groups before and after the treatment were compared. Results After treatment, integral of clinical symptom in both groups were obviously improved compared with before treatment (P<0.05), but there was no significant difference between the two groups (P>0.05). After treatment, gastric half-emptying time and antral contraction frequency of the both groups were obviously improved, with significant difference (P<0.05), but there was no significant difference between the two groups (P>0.05). The total effectiveness of the treatment group was 97.2% (35/36) and the control group was 94.4% (34/36), with no significantly difference (P>0.05).Conclusion Dong’s Pushing Epiglottis Cartilage Method has relatively good clinical efficacy for the treatment of children food retention.

Objective To investigate BRAFV600E mutation and sodium iodide symporter (NIS) expression and its clinical significance in papillary thyroid carcinomas (PTC).Methods BRAFV600E mutation was evaluated by direct sequencing and BRAFV600E mutation was determined in 40 cases of PTC.NIS expression was examined by means of immunohistochemistry.The relationship between BRAFV600E mutation and the clinicopathologic features of PTC was analyzed.The relationship between NIS expression and BRAFV600E mutation in PTC was analyzed.Results Positive BRAFV600E mutation was determined in 23 of 40 cases of PTC (57.5％),whereas positive NIS expression was showed in 7 of 40 cases (12.5％).BRAFV600E mutation was associated with extrathyroid invasion and a high risk of disease recurrence in PTC (P ＜ 0.05).Positive NIS expression was found in only one of 23 cases of PTC with BRAFV600E mutation,and positive NIS expression was associated with a statistically significant lower BRAFV600E mutation in PTC (P =0.011).Conclusions BRAFV600E mutation might be associated with higher aggressiveness,higher disease recurrence and a poorer prognosis.Lower NIS expression may be responsible for poor 131I uptake in

Objective To evaluate the effects of treatment for the distal radial osteoporotic fractures in elder patients with Volar Locking Compression Plating (LCP)fixation. Methods 30 old patients who suffered from the severe osteoporotic distal radial fractures were treated with LCP. In this group all the fractures were more severe than type 2B according to Melone classification. The results of treatment were evaluated by comparing pre and post operative functions and X rays of involved wrists. Results 26 of the 30 patients experienced no wrist pain and were satisfied with the functions of the suffered wrists in their daily postoperative activities. 2 patients still felt wrist pain and needed to take some pain killers and other 2 experienced mild finger movement limitations. These data were improved postoperatively to the average palmar tilt of 3.38 degrees, radial inclination of 18.9 degrees and the radial length 0.9cm longer between the ulnar head and the tip of the radial styloid. The radial length was found 0.2 mm shorter in 2 cases in the latest follow up than that measured before. No severe complications were found in this group. Conclusion For the unstable distal radial osteoporotic fractures in the elderly patients, Volar Locking Compression plating (LCP)fixation is one of the effective treatments, because this procedure can restore and sustain the distal radial length and smooth articular surface after the fracture reduction.

The expression of Rap1 GAP protein was detected in 69 cases of papillary thyroid carcinoma and adjacent normal thyroid tissues with immunohistochemistry method.Methylation of Rapl GAP gene was analyzed by methylation-specific-PCR (MSP) in these tissues.The immunohistochemistry results indicated that the Rap1GAP protein was down-regulated in tumor tissues of 54 ( 78％ ) cases compared with normal thyroid tissues.Statistical analysis demonstrated that the decreased level of Rap1 GAP protein expression was significantly correlated with the tumor stage T according to American Joint Committee on Cancer ( AJCC,P =0.043 ).The MSP results demonstrated that 46 cases of Rap1GAP gene methylation were detected in 54 cases with down-regulated expression of Rap1GAP (66.7％),but only 1 case of methylation was found in 15 cases without obvious change of Rap1GAP expression (6.67％),showing significant difference ( P＜0.01 ).There was no methylation in normal thyroid tissues.These results suggest that raised methylation of promoter region may contribute to the low expression of Rap1GAP protein in papillary thyroid carcinoma.
