To enhance the fusion of graft bone in thoracolumbar vertebrae and minimize the postoperative loss of correction, short-segment pedicle screw fixation was reinforced with posterior moselizee bone grafting in vertebrae for spinal fusion in patients with thoracrolumbar vertebrate fractures. Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A (n=20) were reinforced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B (n=50) did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B (group A: 6.4 degree; group B: 5.4 degree)/ At the end of follow-up, kyphosis correction was maintained in group A but lost in group B (P=0.0001). Postoperatively, greater anterior height was achieved in group A than in group B (P<0.01). During follow-up study, anterior vertebral height was maintained only in Group A (P<0.001). Both group A and group B showed good Denis pain scores (P1 and P2) but group A outdid group B in terms of control of severe and constant pain (P4 and P5). By Frankel criteria, the changes in neurological functions in group A was better than those of group B (P<0.001). It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with thoracolumbar vertebrate fractures, decreases the instrument failure and provides better postoperative pain control than without the morselized bone grafting.

OBJECTIVETo study clinical value of shear wave elastography (SWE) in the evaluation of neck-shoulder myofascial pain syndrome.
METHODSFrom December 2013 to July 2014,30 patients diagnosed as neck-shoulder myofascial pain syndrome were in the treatment group,including 17 males and 13 females, with an average age of (44 ± 3) years old. Thirty healthy people were in the control group, including 22 males and 8 females, with a mean age of (37 ± 5) years old. The patients in the treatment group were treated with manipulation, once every other day, total 7 times. The SWE was used to detect tension part of trapezius muscle of patients in the treatment group before and after treatment, as well as to detect muscle belly at the descending part of trapezius muscle in the control group. The tissue elasticity and Yang's modulus value were recorded and compared.
RESULTSThe tissue elasticity chart of patients in the treatment group before treatment was mainly greenish blue with the score of 3.70 ± 1.53, and the Yang's modulus was (43.4 ± 15.6) kPa. The tissue elasticity figure after treatment was mainly blue with the score of 2.40 ± 0.87, and the Yang's modulus was (29.0 ± 5.9) kPa. Whereas in the control group, the tissue elasticity figure was mainly blue with the score of 1.60 ± 0.72, and the Yang's modulus was (24.0 ± 7.6) kPa. These were statistical differences between the two groups (P = 0.000).
CONCLUSIONSWE can be used as an evaluation method of manipulation treatment for neck-shoulder myofascial pain syndrome, which is an objective and sensitive detection method.

Objective:To provide microsurgical anatomy data in the course, branch, distribution, arterial network profile of the submental artery and the range of the flap excision in submental flap transplantation.Methods:From March, 2015 to March, 2020, a total of 36 head and neck cast specimens were studied. Acrylic-butadience-styrene plastic (ABS) filler were perfused into the external carotid artery to make cast specimens. The course, branching, distribution and the arterial framework of the submental artery under a surgical microscope were investigated.Results:The submental artery originated from the facial artery before reaching the lower edge of the mandible (1.50±0.50) cm, with a diameter of (1.50±0.85) (0.6-2.3) mm. The main trunk of submental artery was (5.5±0.5) cm in length, which ran forward along the lower edge of the mandible and branched out (9.0±3.0) (7-13) branches with diameters between 0.1-0.5 mm, and mainly distributed to skin and superficial fascia of the submental area. The main trunk of submental artery divided into ascending, horizontal and descending branches about 3.0 cm of the midline of the mandible. The ascending branch went upwards over the lower edge of the mandible and joined up with the lower labial arch or participated in the formation of the lower labial arch; the horizontal branch divided into several branches and joined up with the branches from the opposite side; the descending branch branched posteriorly and inferiorly, joined up with branches of lingual artery and superior thyroid artery. The branches of the submental artery and the branches of the peripheral arteries were joined up in the submental area to form the submental artery network. The diameter of the vessels in the network ranged 0.1-0.2 mm. The arterial network was built in the form of 1 to 3 layers, and the area of main network was about 7.0 cm×5.0 cm.Conclusion:The submental artery has a long trunk, many branches and abundant anastomoses between the branches, forming a dense submental artery network, which provides sufficient pedicle length, rich blood supply and cutting area for submental flap. The flap can be transplanted free or transposed. The best location of submental flap is near the midline of arterial network, and the appropriate area is 7.0 cm×5.0 cm.

Objective To identify serum biomarkers for rheumatoid arthritis(RA)by protein finger- print pattern. Methods One hundred and forty-one serum samples of 90 RA patients, 20 systemic lupus ery- thematosus(SLE)patients, and 31 healthy individuals were randomly divided into training set(n=93, 60 RA patients, 13 SLE patients and 20 healthy individuals)and test set(n=48, 30 RA patients, 7 SLE patients and 11 healthy individuals). They were detected by surface enhanced laser desorption/ionization-time of flight- mass spectrometry(SELDI-TOF-MS). The protein fingerprint pattern obtained from SELDI-TOF was trained by a multi-layer artificial neural network(ANN)to establish a diagnostic model. Results The detective mod- el obtained by ANN was used to detect the 48 unknown serum samples. The sensitivity and specificity for RA detection was 90% and 90.9% respectively. Conclusion In comparison with traditional methods, SELDI- TOF-MS could identify new serum biomarkers in RA. Combined with ANN, it provides high sensitivity and specificity for RA diagnosis.
