Objective To explore the influence of levothyroxine(L-T4) in the treatment of primary hypothyroidism on myocardial enzymes and lipids.Methods 78 patients with primary hypothyroidism were selected and treated with L-T4 for 12 weeks.The fasting serum levels promote thyroid hormone(TSH),free T3 (FT3),free T4 (FT4),total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterol (LDL-C),aspartate aminotransferase enzyme (AST),creatine kinase (CK) and its isoenzyme (CK-MB),lactate dehydrogenase(LDH) were monitored and analyzed before and after treatment.Results After L-T4 treatment for 12 weeks,compared with before treatment,TSH,TC,TG,LDL-C,CK,CK-MB,LDH,AST were significantly decreased or restored (t =10.5223,26.8498,22.7699,16.2735,22.9329,13.1910,32.0907,22.9597,all P ＜ 0.01).The FT3 was negatively correlated with TG (r =-0.3782),LDL-C(r =-0.3506),AST(r =-0.2843),LDH(r =-0.2974),CK(r =-0.3726) (all P ＜ 0.01)and CK-MB(r =-0.2559) (P ＜ 0.05).FT4 was negatively correlated with TC (r =-0.2660),TG (r =-0.4661),LDL-C(r=-0.5119),LDH(r=-0.5936),CK(r=-0.4877),CK-MB(r=-0.5463) (all P＜0.01)and AST(r =-0.2328) (P ＜0.05).TSH was positively correlated with TC(r =0.5341),TG(r =0.7567),LDL-C(r =0.8240),AST (r =0.3923),LDH (r =0.8073),CK (r =0.9661),CK-MB (r =0.7336) (all P ＜0.01).TSH had,the best correlationship with CK (r =0.9661).Conclusion L-T4 can significantly improve the thyroid function and reduce the blood lipids,myocardial enzymes levels of patients with primary hypothyroidism.

Objective To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome,and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study.Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients,CT in 13 patients as well as MR in 3 patients.Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years).Results Serum HLA B27 antigen was positive in all patients. Both skin and bone abnornalities were found in all patients.Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints,anterior chest and limbs.Sacroiliac joints were asymmetrically involved with imaging features in all patients.Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients,CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling.MR imaging was able to depict edema changes that was not detectable by CT and radiography.Conclusion SAPHO syndrome is a rare disease,but for patients with skin and bone-joint abnormalities,especially with skin palmoplantar pustulosis,acne as well as with imaging features at the sacroiliac joint and anterior chest wall,SAPHO syndrome should be taken into a diagnostic consideration.

BACKGROUND:Intertrochanteric fracture can obtain good curative effects after active effective internal fixation in early stage.
OBJECTIVE:To compare dynamic hip screw+trochanter stabilizing plate and Gamma nail fixation for treatment of Evans type IIIB and type IV intertrochanteric fracture.
METHODS:A total of 67 patients with Evans type IIIB and type IV intertrochanteric fracture, including 28 cases undergoing dynamic hip screw+trochanter stabilizing plate and 39 cases undergoing Gamma nail, were selected from Chongming Branch, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from February 2009 to November 2012. Al patients received antibiotics and functional exercises after treatment. Time of therapy, intraoperative bleeding amount, fracture healing time and Harris Hip Score were retrospectively analyzed in patients of both groups.
RESULTS AND CONCLUSION:Al patients were fol owed up for 6-45 months, averagely 21 months. (1) One patient affected infection in the dynamic hip screw+trochanter stabilizing plate group. He was healed after fixation removal half a year after drug exchange. One obese patient experienced injury again during out-of-bed activity at 3 weeks after treatment in the Gamma nail group. Fracture appeared at distal end of lock pin, and healed after replaced by Gamma nail. Trochanteric stabilizing plate was unstable in four patients of the Gamma nail group. They affected severe pneumonia after over 6 weeks of lying in bed, and healed after treatment in the medical department (2) Coxa vara appeared in two cases of the dynamic hip screw+trochanter stabilizing plate group, and three cases in the Gamma nail group. Fracture healing was achieved in al patients. (3) The time of therapy was longer, and intraoperative bleeding amount was significantly more in the dynamic hip screw+trochanter stabilizing plate group compared with the Gamma nail group (P<0.05). No significant difference in healing time and Harris Hip Score was detected between the two groups (P>0.05). Dynamic hip screw+trochanter stabilizing plate and Gamma nail are effective methods for treatment of Evans type IIIB and type IV intertrochanteric fracture. To choose a suitable fixator, we should aggregately analyze fracture stability, healing state and the degree of osteoporosis.
