Objectives To study the effect of bone mineral density measurement on the diagnosis and treatment of osteoporosis in patients with fragility hip fracture.Methods A retrospective analysis was conducted on 560 cases of elderly patients with fragility hip fracture in our hospital from January 2010 to December 2012.They were divided into two groups with and without the bone mineral density measurement,and compared to study the bone turnover markers detection and osteoporosis treatment.Results Among the 80 cases with the DXA bone mineral density detection,36 cases received the bone turnover markers detection(45.0%),and the rate of osteoporosis treatment in hospital was 70.0%,while the rate of osteoporosis treatment after discharge was 57.5%.Among the 480 cases without DXA bone mineral density detection,none received bone turnover markers detection,and the rate of osteoporosis treatment in hospital was 42.1%,while the rate of osteoporosis treatment after discharge was 36.7%.Conclusions The detection rate of bone mineral density and the diagnosis and treatment rate of osteoporosis are low in patients with fragility hip fracture.DXA bone mineral density measurement is helpful to improve the detection rate of bone turnover markers and the treatment rate of osteoporosis.

Objective]To discuss the effect of sciatic nerve injury on the expressions of tumor necrosis factor-alpha(TNF-α), interleukin-1β(IL-1β)and interleukin-10(IL-10)in anterior cingulate cortex(ACC),and further to explain their roles resided in the development of neuropathic pain.[Method]With use of the methods of behavioral test,western blot and immunohistochemistry, we examine the effects of spared sciatic nerve injury(SNI)on the expressions of TNF-α,IL-1β,and IL-10 in ACC,and observe the effect of the neutralizing antibody of TNF-α,IL-1β on the rat mechanical allodynia.[Result]In present experiment ,SNI increased the protein levels of TNF-α,IL-10,but not IL-1β in ACC. Increased TNF-α-IR and IL-10-IR in ACC is located in neurons ,but not astrocytes and microglia at 7 d following L5-VRT. Pre-treatment with anti-TNFα antibody but not anti-IL-1βantibody into ACC significantly increased the rat paw withdrawal threshold to von Frey hairs.[Conclusion]These data suggested that the increased TNF-αin ACC neurons might be responsible for the development of neuropathic pain.

BACKGROUND:StageIorIIKummel’s diseaseisusualy suggested to be treated with percutaneous vertebroplasty (PVP) orpercutaneous kyphoplasty (PKP). Stage IIIKummel’s diseasewith neurologic deficit is treated with open decompression, cement-augmented combined with internalfixation. However, surgical options for stage IIIKummel’s diseasewithdural saccompression butwithnonervous symptoms arein disputeand rarely reported. OBJECTIVE:To investigatethesurgical options of Kummel’s disease with vertebral posterior walcolapse. METHODS:Fourteen patients with Kummel’s disease with vertebral posterior wal colapse wereenroled as experimental groupandtreated with PVP or PKP based on the degree of postural reduction.Another28 patients with osteoporotic vertebral fracture as control group were treated with PKP. Thenalpatients were folowed up to observe vertebralheight, Cobb angle, visual analog scale and the Oswestry disability index. RESULTS AND CONCLUSION:After folowed up for 10 to 42 months, therestoredvertebralheight, Cobb angle, visual analog scale and Oswestry disability index were significantly improved inthetwo groups (P<0.05). Thepostoperativevertebralheight intheexperimental group was significantly higher than thatinthe control group(P< 0.05).Butno significant differencesin Cobb angle, visual analog scalescoresand Oswestry disability indexwere found between thetwo groups after operation (P> 0.05). These data suggest that based on the degree of postural reduction, individualizedPVP or PKP for Kummel’s disease with vertebral posterior wal colapsecanattain satisfactoryoutcomes.

Objective To investigate the correlation of incident pneumonia and serum 25-hydroxyvitamin D[25(OH)D] levels in elderly patients with fragility hip fractures.Methods 132 patients with fragility hip fractures were divided into the pneumonia group [n=43,14 males and 29 females,aged 63-97 years,a mean age of (83.8±7.1) years] and the non-pneumonia group [n=89,28 males and 61 females,aged 60-93 years,a mean age of (77.1±8.1) years].Fasting venous blood samples were taken on the second day after admission.Serum 25 (OH)D levels were measured by radioimmunoassay.Results Vitamin D deficiency was found in 90.7％ of the patients in the pneumonia group,52.8％ in the non-pneumonia group (x2=24.953,P＜0.05).The age and smoking rate were higher in the pneumonia group than in the non-pneumonia group (t=4.661,P＜ 0.05;x2 =4.459,P=0.035).Logistic regression analysis showed that serum 25(OH)D levels,age and smoking were independent impact factors for pneumonia.When serum 25(OH)D levels were less than or equal to 20 g/L,the incidence of pneumonia was increased and the risk of pneumonia was 8.66 times higher than that for patients with normal 25 (OH)D levels.Conclusions The risk of pneumonia in patients with brittle hip fractures is correlated with age,smoking and the serum 25-hydroxyvitamin D level,with the latter as a major risk factor.Patients with brittle hip fractures should be supplemented with vitamin D as early as possible in order to reduce the risk of incident of pneumonia.

Objective To observe the mortality of fragile hip fractures and evaluate the death-associated risk factors.Methods 100 men and 186 women aged 50 to 97 (mean,77.09± 10.65) years old who had fragile hip fracture over 50 years old from 2010 to 2012 were followed up,and the clinical data were retrospectively analyzed.Three months,one year and the total mortality of following time were calculated.Mortality-related risk factors were evaluated including age,gender,and surgery,duration from injury to operation,pulmonary infection,number and kind of complications.Results The 286 patients were followed up between 6 months and 42 months,with 21.42±9.88 months in average.The three month mortality was 7.69％,the patients who were followed up over one year were 231 cases,the one year mortality was 16.02％,and the total mortality of following time was 17.48％.The mortality was associated with age,gender,surgery,duration from injury to operation,number of complications,pre-injury cardiovascular disease and respiratory system diseases,and pulmonary infection.A Binary Logistic Regression analysis revealed that the independent risk factors affecting the mortality included age (OR=5.385,P=0.003),surgery (OR=21.217,P=0.000),number of complications (OR=9.038,P=0.000),pre-injury cardiovascular disease (OR=3.201,P=0.041).Conclusion The early mortality of fragile hip fractures was high and was associated with many risk factors.Age,surgery,number of complications and pre-injury cardiovascular disease were the independent risk factors affecting the mortality of fragile hip fractures.The positive treatment with complications,early surgery in condition allowed,can lower the early mortality.

Red blood cell (RBC) transfusion is a clinically effective therapy in anemia, for example in patients with malignancies (Shander et al., 2020), bleeding (Odutayo et al., 2017), and preoperative anemia (Padmanabhan et al., 2019). The past few decades have witnessed a shortage of blood for transfusion due to limited health insurance coverage for blood use and the rapid expansion of hospitals (Chen et al., 2011; Shi et al., 2014). Blood donation levels may easily be affected by general changes in the environment, policy, major events such as disasters, and public sentiment (Hu et al., 2019). Meanwhile, the transfusion of allogeneic RBC is a double-edged sword, increasing the possibility of infectious and immunological complications, and also leading to higher morbidity and mortality after transfusion (Frank et al., 2012). Considering that the continual shortfall has been increasingly prominent, identifying the factors associated with RBC transfusion could help blood transfusion departments to improve their supply of blood products as well as their inventory management (O'Donnell et al., 2018).
