RESUMEN
Sarcopenia and hip fractures are musculoskeletal system diseases, which cause great harm to the health of geriatric population.As sarcopenia is receiving more and more attention in recent years, its relationship with hip fractures has been increasingly noted.The paper summarized the epidemiological evidences on the relationship between sarcopenia and hip fracture and investigated the possible etiologic mechanism by which sarcopenia triggers hip fractures.
RESUMEN
The knee osteoarthritis (KOA)is a kind of degenerative disease,which is more common in the elderly.In recent years,according to the Knee Uneven Settlement Theory,a new treatment method for the knee osteoarthritis by using the proximal fibula osteotomy is popularized in many hospitals.In this article,we reported 1 case undergoing the total knee arthroplasty after the proximal fibula osteotomy for the treatment of knee osteoarthritis and reviewed the relevant literatures.

RESUMEN
Objective To evaluate the feasibility of a new reduction technique by comparing 2 reduction strategies in the treatment of distal femoral fractures with less invasive stabilization system (LISS).Methods A retrospective study was performed on the clinical data of 31 patients with distal femoral fracture who had been treated with LISS at Department of Orthopedics,Huadong Hospital Affiliated to Fudan University from January 2014 to December 2016.They were 11 males and 21 females.In 21 of them reduction of the fracture ends was conducted before fixation of the distal femur (strategy one),involving 9 males and 12 females with an age of 73.2 ± 16.2 years;in the other 10 of them reduction of the fracture ends was conducted after fixation of the distal femur (strategy two),involving 2 males and 8 females with an age of 70.8 ± 20.4 years.The 2 groups were compared in terms of perioperative blood loss,operation time,postoperative complications and the modified Hospital for Special Surgery (HSS) score of the affected knee joint.The enumeration data were compared with Fisher exact test and the measurement data with t-test.Results The 2 groups were compatible due to the insignificant differences in their preoperative general data (P ＞ 0.05).There were no significant differences between the 2 groups in terms of perioperative blood loss (593.3 ± 99.1 mL versus 494.7 ± 94.4 mL),operation time (121.7 ± 8.1 min versus 106.4 ± 8.5 min),rate of postoperative complications (0 versus 10％) and modified HSS score of the affected knee joint (83.8 ± 1.4 versus 84.2 ± 3.1) (P ＞ 0.05).Conclusions The 2 reduction strategies can lead to similar surgical effects in the treatment of distal femoral fractures with LISS.Strategy two can be a feasible alternative for surgeons with its theoretical advantage of simplicity.
RESUMEN
Objective To investigate the relationship between suspected ankylosing spondylitis and HLA‐B27 antigen by detec‐ting the positive frequency of HLA‐B27antigen in 872 suspected AS patients ,and evaluate its clinical significance .Methods The positive frequency of HLA‐B27 on the T lymphocyte membrane were detected by flow eytometer in 872 suspected AS patients .Re‐sults Among the 872 suspected AS patients the ratio between male and female was 1 .8∶1 ,the positive rate of antigen HLA‐B27 was 27 .29% ,and the male and female patients′positive rates of HLA‐B27 antigen were 32 .50% and 17 .95% ,respectively (P<0 .05) .The male and female patients′ expression percentage of B27+ /B7- monoclonal antibody were 39 .16 ± 42 .79 and 20 .96 ± 33 .86 ,respectively(P<0 .05) .The male and female patients′mean fluorescence intension of B27+ /B7- monoclonal antibody were 5 .35 ± 5 .44 and 3 .35 ± 3 .87 ,respectively(P<0 .05) .Conclusion The patients with AS are strongly associated with HLA‐B27 an‐tigen .Detection of HLA‐B27 antigen expression intensity in suspected AS patients with FCM is helpful to diagnosis and differential diagnosis of AS .
RESUMEN
Objective To evaluate the diagnostic value of procalcitonin(PCT),C-reactive protein(CRP),prealbumin(PA)and white blood cell (WBC)count measurements in patients with severe pneumonia.Methods The serum samples of 34 patients with severe pneumonia,68 non-severe pneumonia patients and 40 healthy volunteers were collected.Serum concentrations of PCT,CRP, PA and WBC count of all samples were determined.Results The levels of PCT,CRP,PA and WBC in patients with severe pneu-monia were (24.07±34.77)ng/mL,(98.75 ±69.63)mg/L,(105.65 ±68.88)mg/L,(12.64±7.62)×109/L,which were signifi-cantly higher than those in non-severe pneumonia patients and healthy group(P <0.05).According to ROC analysis,the sensitivity, specificity and Youden index of PCT were 64.7%,77.9%,0.426.Conclusion The level of serum PCT could be used as good bio-marker for severe pneumonia.Detection of PCT,CRP and WBC together plays an important role in the diagnosis of severe pneumo-nia.
