Objective To investigate the incidence and relative factors of post-stroke depression (PSD). Methods 520 patients with stroke were assessed by 17-item Hamilton Depression Rating Scales (HAMD). A self-designed register form was analysed in 520 stroke survivorsA multiple factor analysis with the logistic regression method was carried out on the basis of these data. Results Among them, 178 cases (34.2%) were identified as depression. The minor, moderate and major incedenses were 20.2%, 10.4% and 3.7% respectively. In addition, stepwise regression analysis shows that important risk factors involved in PSD contained depression history, sex, family harmony, accompanying disease, neurological deficit and stoke course. Conclusion The factors above were the major predictive factors and useful for PSD prevention

OBJECTIVETo evaluate the clinical results of dorsal approach and Weil osteotomy in treating the injury of the plantar plate in second metatarsophalangeal joint.

METHODSEight feet with plantar plate tear in five cases were treated by plantar plate repairment through dorsal approach and Weil osteotomy from June 2012 to December 2013. The mean age of the patients was 52 years old. All the patients were followed up for 6 to 12 months. American Orthopaedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) were used to evaluate the clinical effect.

RESULTSThe second metatarsophalangeal joint stability recovered and the pain released in all patients. Postoperative VAS was lower and AOFAS was higher than preoperative.

CONCLUSIONCombined dorsal approach and Weil osteotomy can effectively release the pian of plantar plate, stabilize the metatarsophalangeal joint, decrease the incidence rate of postoperative subluxation and anchylosis in treating plantar plate tears in the second metatarsophalangeal joint.

Objective To discuss the clinical effects of internal fixation with pubic nails and sacroiliac screws aided by 3D navigation for pelvic fractures of Tile type B2 or B3. Methods A total of 27 patients with pelvic fracture of Tile type B2 or B3 received operative treatment in our hospital from De-cember 2013 to December 2016. They were 15 men and 12 women, aged from 20 to 68 years ( average, 39. 2 years ) . According to the Tile classification, 12 cases were type B2. 1, 8 type B2. 2, and 7 type B3. Of them, 20 were unilateral pubic rami fractures and 7 bilateral pubic rami fractures; there were 3 dislocations of the sacroiliac joint, 17 fractures of the sacral Denis regionⅠ, and 7 fractures of the sacral Denis regionⅡ. All the 27 cases were treated by internal fixation with retrograde pubic nails and sacroiliac screws aided by 3D navi-gation. Quality of fracture reduction, functional recovery of the pelvis and postoperative complications were recorded to evaluate the clinical effects. Results Totally 26 out of the 27 patients were followed up for 6 to 18 months ( average, 11. 4 months ) , with one lost to the follow-up. According to the Matta scoring, the pelvic reduction was evaluated as excellent in 20, as good in 4 and as fair in 2 cases, yielding an excellent and good rate of 92. 3％. All the fractures united after 12 to 20 weeks ( average, 13. 8 weeks ) . According to the Majeed scoring at the final follow-ups, the pelvic function was evaluated as excellent in 20, as good in 3 and as fair in 3 cases, giving an excellent and good rate of 88. 5％. Screw loosening happened in one patient who had ambulated too early. No permanent pain, wound infection, neurovascular injury, heterotopic ossification or thrombosis occurred. Conclusion For the treatment of pelvic fractures of Tile type B2 or B3, internal fixation with pubic nails and sacroiliac screws aided by 3D navigation can lead to satisfactory short-term outcomes due to advantages of limited operative invasion, short operation time and limited intraoperative blood loss.

Objective To determine the possible differences in DNA methylation of benign and malignant thyroid tumors and its role in tumorgenesis and tumor progression. Methods Infinium human methylation 450 bead chip platform was utilized to screen the whole-genome of benign and malignant thyroid tumor tissues surgically removed from a patient for the determination of their DNA methylation levels. The genes with significant differences in methylation were analyzed for their functional pathways with bioinformatics. Results There were significant differences in DNA methylation between benign and malignant thyroid tumor. The inflammation-related pathways, such as T cell, Jak-STAT and cytokine-cytokine receptor signaling pathways involved in the biological process of tumorgenesis and tumor progression. Conclusions The differences in DNA methylation between benign and malignant reveal a close relationship between inflammation and tumorgenesis and tumor progression and provide a novel method for investigation of thyroid cancer development and target drug discovery.

Objective To explore the correlation between anti-cyclic citrullinated peptide(A-CCP) antibody and tumor necrosis factor(TNF)-?, rheumatoid factor(RF), ESR, PLT count and clinical features in patients with rheumatoid arthritis(RA), and the outcome of unclassified arthritis(arthralgia)patients after six months follow up. The value of A-CCP antibdy in the diagnosis of early RA and its pathogenetic roles is in- vestigated. Methods A-CCP antibody and TNF-?were detected by ELISA and the RF was tested by the rate scatting immunity method in 91 RA patients, 46 unclassified arthritis(arthralgia)patients and 45 other rheumatic diseases patients. Results A-CCP antibody levels in serum correlated significantly with TNF-?levels, PLT count and the degree of joint swelling in RA and unclassified arthritis(arthralgia)patients(r= 0.854, P=0.O00; r=0.882, P=0.000; r=0.318, P=0.002; r=0.486, P=0.001; r=0.291, P=0.005; r=0.731, P= 0.000 respectively). A-CCP antibody levels in serum was weakly negatively correlated with the gripping power in RA patients(r=0.228, P=0.030). And it was weakly correlated with ESR in unclassified arthritis(arthrai- gia)patients(r=0.365, P=0.013). Compared with other rheumatic diseases patients, A-CCP antibody levlels in serum increased significantly in RA and unclassified arthritis(arthralgia)patients(P=0.000). Compared with normal controls, it increased in other rheumatic diseases patients(P=0.011). Twenty-four patients had positive A-CCP antibody in 46 unclassified arthritis(arthralgia)patients. Thirty-two out of 46 unclassified arthritis(arthralgia)patients were early RA after 6 monthes follow up. 95.8%(23/24)unclassified arthritis (arthralgia)patients with positive A-CCP antibody were early RA. Conclusion A-CCP antibody reflects disease activity in certain extent. It's benefit to the diagnosis of early RA. High A-CCPantibody levels com- bined with high levels of TNF-?, ESR, PLT count and joint swelling can help the diagnosis of early RA.
