Objective To detect serum Vaspin level in subjects with normal glucose regulation(NGR)and newly-diagnosed type 2 diabetes mellitus (T2DM) ,and to investigate the association between serum Vaspin and body mass index (BMI), age, gender, glycometabolism and lipemetabolism and insulin sensitivity index. Methods The fasting serum levels of Vaspin were measured in 48 normal controls and 66 T2DM patients using enzyme linked immunosorbent assay ( ELISA ). BMI, waist-hip ratio (WHR) and % body fat were measured,as well as fasting blood glucose (FBG), HBA1C, lipids and insulin levels. Results The fast serum Vaspin concentrations in the obese T2DM patients was ( 1.13 ±0. 25 ) μg/L,which were significantly higher than that in the non-obese T2DM patients (0. 65 ± 0. 13 ) μg/L (P ＜ 0. 01 ). In the NGR group, the fast serum Vaspin concentrations in the obese was (0. 95 ± 0. 11 ) μg/L, which were significantly higher than that in the non-obese (0. 38 ± 0. 18) μg/L( P ＜ 0. 01 ). In the T2DM group, serum Vaspin concentration in females ( [0. 92 ± 0. 35]μg/L) was higher than in males ([0.76 ± 0. 22] μg/L) (P ＜ 0.01 ). In the NGR group, serum Vaspin concentration in females was also higher than that in males ( [1.05 ± 0. 21] μg/L vs [0. 48 ± 0. 14] μg/L) )(P＜0. 01 ). Serum Vaspin level was positively correlated with BMI,WHR,% Body Fat,fasting insulin(FINS)and insulin sensitivity index (ISI) (r = 0. 365,0. 214,0. 238,0. 183 and 0. 147, respectively, Ps ＜ 0. 05 ). The multiple stepwise regression analysis showed that gender( R2 = 0. 161, P ＜ 0. 01 ), ISI ( R2 = 0. 183, P ＜ 0. 01 )and WHR( R2 = 0. 216, P ＜ 0. 01 ) were independent variables associated with Vaspin. Conclusion Serum vaspin level significantly increases in subjects with obesity, and independently associated with gender, ISI,WHR. These findings suggest that serum Vaspin may be involved in the pathophysiology of insulin resistance syndrome.

BACKGROUND:There are many reports on the clinical effect of total knee arthroplasty in the treatment of advanced rheumatoid arthritis, but the reports on the effect of total knee arthroplasty on the disease activity in patients with rheumatoid arthritis are rare. Therefore, the more clinical evidences are needed for supporting.
OBJECTIVE:To explore the effect of total knee arthroplasty on disease activity in patients with rheumatoid arthritis.
METHODS:109 patients with rheumatoid arthritis were included;48 cases in the replacement group, and received total knee arthroplasty combined with internal medicine medications;the 61 cases in the drug treatment group were treated with simple internal medicine medications. The rheumatoid factor, blood sedimentation rate and C-reactive protein levels of the patients in two groups were measured before treatment, 1 and 2 years after treatment, and the Ishikawa joint function scoring criteria was used to assess the functions.
RESULTS AND CONCLUSION:There were no significant differences in the rheumatoid factor, blood sedimentation rate and C-reactive protein levels between two groups before treatment (P>0.05). At 1 and 2 years after treatment, the indicators in the drug treatment group were higher than those in the replacement group (P<0.05);the indicators in the two groups at 2 years after treatment were significantly lower than those before treatment (P<0.05). The rheumatoid arthritis symptom scores of the affected joints of the patients in two groups were significantly improved, especial y the pain, swel and subjective attitudes, and the replacement group was better than the drug treatment group (P<0.05). The total knee arthroplasty can affect the disease activity of rheumatoid arthritis in short-term, and the effect of total knee arthroplasty is better than simple drug treatment.

Objective To explore the initial effects of the treatment of proximal femoral nail-helical blade (PFNA) in elderly patients with intertrochanteric fracture of the incomplete lateral wall type. Methods A total of 25 patients were enrolled in this study including 8 cases of type A2, 17 cases of type A3 according to AO classification. All patients under-went three-dimensional CT scan. In all patients with type A2 fracture, there were 6 cases with coronal plane fracture on the greater trochanter, and PFNA was used instead of DHS when an iatrogenic fracture occurred in 2 patients. All other patients were treated with closed reduction and fixed with PFNA. Results All patients healed and the average healing time was 11 weeks, one patient fell down once again and the fracture occurred on the shaft, when a long PFNA was used, both of the frac-tures healed 14 weeks after surgery. In all of the 25 patients,1 patient died due to cerebral hemorrhage 13 months after sur-gery;2 patients needed walking aids due to the presence of osteoarthritis of the knee and calf muscular venous thrombosis was diagnosed in 3 cases. No complications were found in the other patients, such as infection, nonunion and fixation failure. According to the Harris hip score system, there were 14 cases of“excellent”,8 cases of“good”,2 cases of“fair”and1 pa-tient of“poor”.Conclusion The PFNA treatment can provide a good fixation for intertrochanteric fractures of incomplete lateral wall type, which allow patients to do exercise early and achieve an excellent initial outcome.

[Abstract ] Objective C reactive protein (CRP), an in-flammatory maker, increased significantly among diabetes mellitus and other metabolic diseases.Meanwhile, adiponectin plays a vital role in anti-atherogenic, anti-inflammatory and anti-diabetic poten-tials.Further, it decreased in diabetes mellitus.To investigate the effects of C-reactive protein in the expression of high-molecular-weight adiponectin ( HMWA) and adiponectin multimerization. Methods The fully differentiated 3T3-L1 cells were respectively treated with 50μg/mL CRP for 0 h、6 h、12 h and 24 h , and different doses of CRP with 0μg/mL、5μg/mL、25μg/mL、50μg/mL for 24 h.The expres-sion of HMWA was further detected by Western blot.Additionally,
the mRNA expressions of adiponectin assembly related genes ( Ero1-L、DsbA-L、ERp44 ) were detected by Real time PCR after 50μg/mL CRP treatment for 24 h. Results After 24 h treatment, 25μg/mL CRP and 50μg/mL CRP resulted in a substantial reduction ( [70 ±7]%vs [44 ±7]%, P<0.05) while 5μg/mL CRP revealed no change.With the dose of 50μg/mL CRP treated, the ex-pression of HWMA were both inhibited after the 12 h and 24 h CRP treatment ([71 ±6]%vs [48 ±11]%, P<0.05), but for the 6 h CRP treatment group, HWMA remained unchanged.Additionally, CRP inhibited Ero1-L(86 ±10)%and DsbA-L(72 ±6)%gene expression and upregulated the expression of ERp44(141 ±23)%. Conclusion CRP decreases HMWA expression in a dose and time-dependent manner and inhibits the multimerization of adiponectin, thus weaken the benefits of adiponectin in diabetes.
