[PMID: 36967755 PMCID: PMC10031038 DOI: 10.3389/fendo.2023.1133674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 02/13/2023] [Indexed: 03/11/2023] Open
Abstract
BACKGROUND Glucocorticoid usage and alcohol abuse are the most widely accepted risk factors for nontraumatic osteonecrosis of femoral head (ONFH). Despite distinct etiologies between glucocorticoid-associated ONFH (GONFH) and alcohol-associated ONFH (AONFH), little is known about the differences of the microarchitectural and histomorphologic characteristics between these subtypes of ONFH. PURPOSES To investigate bone microarchitecture, bone remodeling activity and histomorphology characteristics of different regions in femoral heads between GONFH and AONFH. METHODS From September 2015 to October 2020, 85 patients diagnosed with GONFH and AONFH were recruited. Femoral heads were obtained after total hip replacement. Femoral head specimens were obtained from 42 patients (50 hips) with GONFH and 43 patients (50 hips) with AONFH. Micro-CT was utilized to assess the microstructure of 9 regions of interest (ROIs) in the femoral head. Along the supero-inferior orientation, the femoral head was divided into necrotic region, reactive interface, and normal region; along the medio-lateral orientation, the femoral head was divided into medial region, central region and lateral region. Decalcified and undecalcified bone histology was subsequently performed to evaluate histopathological alterations and bone remodeling levels. RESULTS In the necrotic region, most of the microarchitectural parameters did not differ significantly between GONFH and AONFH, whereas both the reactive interface and normal region revealed a less sclerotic microarchitecture but a higher bone remodeling level in GONFH than AONFH. Despite similar necrotic pathological manifestations, subchondral trabecular microfracture in the necrotic region was more severe and vasculature of the reactive interface was more abundant in GONFH. CONCLUSIONS GONFH and AONFH shared similar microarchitecture and histopathological features in the necrotic region, while GONFH exhibited a less sclerotic microarchitecture and a more active bone metabolic status in both the reactive interface and normal region. These differences between GONFH and AONFH in bone microarchitectural and histopathological characteristics might contribute to the development of disease-modifying prevention strategies and treatments for ONFH, taking into etiologies.

Abstract
OBJECTIVE To review the research progress of pathogenesis and genetics of alcohol-induced osteonecrosis of the femoral head (AIONFH). METHODS The relevant domestic and foreign literature in recent years was extensively reviewed. The pathogenesis, the relationship between gene polymorphism and susceptibility, the related factors of disease progression, and the potential therapeutic targets of AIONFH were summarized. RESULTS AIONFH is a refractory orthopedic disease caused by excessive drinking, seriously affecting the daily life of patients due to its high disability rate. The pathogenesis of AIONFH includes lipid metabolism disorder, endothelial dysfunction, bone homeostasis imbalance, and et al. Gene polymorphism and non-coding RNA are also involved. The hematological and molecular changes involved in AIONFH may be used as early diagnostic markers and potential therapeutic targets of the disease. CONCLUSION The pathogenesis of AIONFH has not been fully elucidated. Research based on genetics, including gene polymorphism and non-coding RNA, combined with next-generation sequencing technology, may provide directions for future research on the mechanism and discovery of potential therapeutic targets.

Abstract
Background: To study the pathogenesis of steroid-induced femoral head osteonecrosis, an ideal animal model is very important. As experimental animals, mice are beneficial for studying the pathogenesis of disease. However, there are currently few mouse models of steroid-induced femoral head osteonecrosis, and there are many questions that require further exploration and research.Purposes: The purpose of this study was to establish a new model of osteonecrosis in mice using angiotensin II (Ang II) combined with asparaginase (ASP) and dexamethasone (DEX) and to study the effects of this drug combination on femoral head osteonecrosis in mice.Methods: Male BALB/c mice (n = 60) were randomly divided into three groups. Group A (normal control, NC) was treated with physiological saline and given a normal diet. Group B (DEX + ASP, DA) was given free access to food and water (containing 2 mg/L DEX) and subjected to intraperitoneal injection of ASP (1200 IU/kg twice/week for 8 weeks). Group C (DEX + ASP + Ang II, DAA) was treated the same as group B, it was also given free access to food and water (containing 2 mg/L DEX) and subjected to intraperitoneal injection of ASP (1200 IU/kg twice/week for 8 weeks), but in the 4th and 8th weeks, subcutaneous implantation of a capsule osmotic pump (0.28 mg/kg/day Ang II) was performed. The mice were sacrificed in the 4th and 8th weeks, and the model success rate, mouse mortality rate, body weight, blood lipids, coagulation factors, histopathology, and number of local vessels in the femoral head were evaluated.Results: DAA increased the model success rate [4th week, 30% (DA) vs. 40% (DAA) vs. 0% (NC); 8th week, 40% (DA) vs. 70% (DAA) vs. 0% (NC)]. There was no significant difference in mortality rate between the groups [4th week, 0% (DA) vs. 0% (DAA) vs. 0% (NC); 8th week, 5% (DA) vs. 10% (DAA) vs. 0% (NC)]. DAA affected mouse body weight and significantly affected blood lipids and blood coagulation factors. DAA reduces the number of blood vessels in the femoral head and destroys the local blood supply.Conclusion: Angiotensin II combined with asparaginase and dexamethasone can obviously promote the necrosis of femoral head and provide a new idea for the model and treatment of osteonecrosis.

Abstract
Osteonecrosis resulting from heavy ethanol consumption is one of the major causes of nontraumatic osteonecrosis of the femoral head (ONFH). The underlying pathological and molecular mechanisms remain elusive. In this study, we performed deep RNA sequencing from femoral heads of patients diagnosed with late-stage alcohol-induced ONFH (AIONFH), other types of ONFH and traumatic injury (bone fracture). Genome-wide gene expression analyses identified 690 differentially expressed mRNAs in AIONFH. Gene annotation and pathway analyses revealed significant dysregulated genes involved in hemostasis, angiogenesis and bone remodeling processes from the late-stage AIONFH. Notably, ADH1B, which codes for one of the major alcohol dehydrogenases, is significantly upregulated in AIONFH samples. Further, we found that the ADH1B protein was primarily expressed in smooth muscle cells of the blood vessels, stromal cells and adipocytes of the femoral heads of AIONFH patients; but was absent in other ONFH samples. Our analyses also revealed unique long non-coding RNA (lncRNA) expression profiles and identified novel lncRNAs in AIONFH. In addition, we observed a close co-expression correlation between lncRNAs and mRNAs in AIONFH suggesting that cis-gene regulation represents a major mechanism of action of human femoral lncRNAs. Further, the expression signature of lncRNAs, but not mRNAs, distinguishes AIONFH from other types of ONFH. Taken together, our studies uncovered novel molecular signatures associated with late-stage AIONFH in which the dysregulation of several key signaling pathways within the femoral head may be involved in AIONFH. Subsequently, lncRNAs may serve as potential biomarkers for diagnosis and therapeutic treatment of AIONFH. Further studies are needed to confirm that ADH1B is specifically upregulated in AIONFH and not generally upregulated in patients who consume alcohol excessively.

Abstract
Femoral head osteonecrosis, also known as avascular necrosis, is a disease with a multifactorial etiology, characterized by a profound change of bone architecture, which leads to the diminishing of bone resistance and femoral head collapse. The main causes that lead to femoral head necrosis are represented by the decrease of local blood perfusion and increase of intraosseous pressure, because of an excessive development of adipose tissue in the areolas of the trabecular bone tissue in the femoral head. The histopathological and immunohistochemical (IHC) study performed by us showed that most of bone trabeculae were damaged by necrotic-involutive processes, their sizes being reduced, both regarding their length and their diameter; generally, the spans were thin, fragmented, distanced among them, which led to the occurrence of some large areolar cavities, full of conjunctive tissue, rich in adipocytes. Some of the residual bone spans even presented microfractures. In the structure of the trabecular bone tissue, numerous cavities showed lack of content, which indicates the death of osteocytes inside, while the endosteum appeared very thin, with few osteoprogenitor, flattened, difficult to highlight cells. The IHC study showed a low reaction of the bone reparatory processes and a reduced multiplication capacity of bone cells involved in the remodeling and remake of the diseased bone tissue. Nevertheless, there were identified numerous young conjunctive cells (fibroblasts, myofibroblasts), positive to proliferating cell nuclear antigen (PCNA), cells that have a high capacity of multiplication, participating in the formation of a fibrous conjunctive tissue (sclerous) instead of the damaged bone trabeculae. The formation of fibrous conjunctive tissue causes the reduction of mechanical resistance of the femoral head and its collapse. The IHC study of the microvascularization in the femoral head damaged by aseptic osteonecrosis showed the presence of a very low vascular system, both in the residual bone trabeculae and in the sclerous conjunctive tissue. Of the inflammatory cells present in the spongy bone tissue of the femoral head affected by osteonecrosis, the most numerous ones were the macrophages. Both macrophages and T- and B-lymphocytes had a heterogenous distribution.

Abstract
INTRODUCTION Often referred to as aseptic or osteonecrosis, avascular necrosis (AVN) typically affects people between 30 and 50 years of age. Given the substantial morbidity associated with AVN as well as overlapping age groups of both the military and average age at diagnosis for AVN, the military represents an ideal cohort for a large database study to elicit the incidence and epidemiology of AVN. The purpose of this study was to identify demographic risk factors in the United States military. MATERIALS AND METHODS First-time occurrences for ICD-9-CM codes for all types of AVN (head of humerus, head and neck of femur, medial femoral condyle, talus, and other bone) between 2004 and 2014 were queried in the Defense Medical Epidemiology Database. Multivariate data analysis was performed to obtain adjusted rate (adjusted for age, sex, race, rank, and branch of service). RESULTS Between 2005 and 2014, 2,671 cases of AVN occurred among an at-risk population of 13,820,906 servicemembers for an unadjusted IR of 0.19 per 1,000 person-years. The most common location was located at the proximal femur, responsible for 41.7% of all cases. With an adjusted rate ratio of 18.7, the over 40 age-group accounted for 53.3% of cases. Servicemembers of black race, Senior rank, and the Army branch of service were more at risk for AVN. CONCLUSIONS The overall incidence of AVN was 0.19 per 1,000 person-years. Whilte increasing age had the greatest influence on the development of symptomatic AVN, other statistically significant risk factors were found to be increasing age, black race, senior enlisted rank, and Army branch of service.

Abstract
Osteonecrosis of the femoral head (ONFH) is a devastating disease frequently leading to femoral head collapse and hip arthritis. Specifically, non-traumatic ONFH primarily affects young and middle-aged adults. Although compromised local circulation of the femoral head seems to be pathognomonic for the disease, the pathogenesis is perplexing and continues to be an area of scrutiny and research. Comprehension of the pathogenesis is of crucial importance for developing and guiding treatments for the disease. Therefore, we provide an up-to-date consensus on the pathogenesis of non-traumatic ONFH.

Abstract
Osteonecrosis (ON) is an acquired debilitating skeletal disorder, which is caused by a multitude of traumatic and non-traumatic etiological factors. Vascular damage, mechanical stress and increased intraosseous pressure have been discussed as contributors to ON. The optimal treatment of ON remains to be determined, since the current gold standard, core decompression, is insufficiently effective. Specific properties of mesenchymal stromal cells (MSCs) provide the rationale for their assessment in advanced stages of ON: Osteoinductive potential has been demonstrated and MSC preparations of suitable quality for use as medicinal products have been developed. Here we review the scant information on the use of allogeneic or autologous MSCs in advanced ON as well as potentially supportive data from pre-clinical studies with autologous bone marrow mononuclear cells (auto BM-MNCs), which have been studied quite extensively and the presumed therapeutic effect of which was attributed to the rare MSCs contained in these cell products. Outcomes in clinical trials with MSCs and auto-BM-MNCs remain preliminary and non-definitive, at best promising, with respect to their pharmacological effect. Clearly, though, the application of any of these cell therapies was technically feasible and safe in that it was associated with low complication rates. The heterogeneity of cell type and source, study protocols, cell manufacturing, cell properties, cell doses and surgical techniques might contribute to inconsistent results.

Previous data have shown patients with osteonecrosis of the femoral head (ONFH) have increased lifelong risk of unprovoked venous thromboembolic events (VTE) as compared with the general population, according to sharing common pathological mechanism of endothelial dysfunction. However, whether the risk of VTE increases in those ONFH patients undergoing major hip replacement surgery remains unclear. This is a retrospective nationwide Asian population-based study. From 1997 to 2013, a total of 12,232 ONFH patients receiving partial or total hip replacement for the first time and revision surgeries were retrospectively selected from Taiwan Health Insurance surgical files. By 1:1 matching on age, sex, surgical types, and socioeconomic status, 12,232 subjects without ONFH undergoing similar hip surgery were selected as non-ONFH group. The incidence and risk of post-surgery VTE, including deep venous thrombosis (DVT) and pulmonary embolism (PE), were compared between the ONFH and non-ONFH groups. Results showed that 53.8% of ONFH patients were male and the median age was 61.9 years old. During the mean follow-up period of 6.4 years, the incidences of VTE (1.4% vs. 1.2%), DVT (1.1% vs. 0.9%), and PE (0.4% vs. 0.4%) were slightly but insignificantly higher in the ONFH than in the non-ONFH group undergoing the same types of major hip replacement surgery (all p-values > 0.250). Concordantly, we found no evidence that the risk of VTE was increased in the ONFH patients as compared with the non-ONFH counterparts (adjusted HR 1.14; 95% CI 0.91–1.42; p = 0.262). There were also no increased risks for DVT and PE in the ONFH subgroups stratified by comorbidities, drug exposure to pain-killer or steroid, and follow-up duration after surgery, either. In conclusion, hip arthroplasty in Asian patients with ONFH is associated with similar rates of VTE as compared to patients with non-ONFH diagnoses.

Abstract
Background Genetic risk factors can provide insight into susceptibility for acute pancreatitis (AP) and disease progression towards (infected) necrotizing pancreatitis and persistent organ failure. The aim of the study was to undertake a systematic review of the genetic evidence for AP. Methods Online databases (MEDLINE, Embase, BIOSIS, Web of Science, Cochrane Library) were searched to 8 February 2018. Studies that reported on genetic associations with AP susceptibility, severity and/or complications were eligible for inclusion. Meta‐analyses were performed of variants that were reported by at least two data sources. Venice criteria and Bayesian false‐discovery probability were applied to assess credibility. Results Ninety‐six studies reporting on 181 variants in 79 genes were identified. In agreement with previous meta‐analyses, credible associations were established for SPINK1 (odds ratio (OR) 2·87, 95 per cent c.i. 1·89 to 4·34), IL1B (OR 1·23, 1·06 to 1·42) and IL6 (OR 1·64, 1·15 to 2·32) and disease risk. In addition, two novel credible single‐nucleotide polymorphisms were identified in Asian populations: ALDH2 (OR 0·48, 0·36 to 0·64) and IL18 (OR 1·47, 1·18 to 1·82). Associations of variants in TNF, GSTP1 and CXCL8 genes with disease severity were identified, but were of low credibility. Conclusion Genetic risk factors in genes related to trypsin activation and innate immunity appear to be associated with susceptibility to and severity of AP.

Abstract
BACKGROUND The pathophysiology of osteonecrosis of the femoral head (ONFH) is poorly understood, and the diagnosis is idiopathic in as many as 40% of patients. Genetic and epigenetic etiologies have been postulated, yet no single nucleotide polymorphisms (SNPs) with intuitive biologic implications have been elucidated. QUESTIONS/PURPOSES (1) Do individuals with ONFH share common biologically relevant genetic variants associated with disease development? (2) What is the mechanism by which these SNPs may impact the expression or function of the affected gene or protein? METHODS This retrospective genome-wide association study (GWAS) evaluated participants from the Mayo Clinic Biobank and Mayo Clinic Genome Consortium between August 2009 and March 2017. We included every patient with atraumatic ONFH in each of these respective registries and every control patient in a previous GWAS with an acceptable platform to perform statistical imputation. The study was performed in two phases, with an initial discovery cohort and a subsequent validation cohort. The initial discovery cohort consisted of 102 patients with ONFH and 4125 controls. A logistic regression analysis was used to evaluate associations between SNPs and the risk of ONFH, adjusted for age and sex. Seven SNPs were identified in a gene of biological interest, peroxisome proliferator-activated receptor gamma (PPARG), which were then evaluated in a subsequent validation cohort of 38 patients with ONFH and 464 controls. Age, sex, race, and previous steroid exposure were similar between patients with ONFH and controls in both the discovery and validation cohorts. Separate from the two-phase genetic investigation, we performed targeted pharmacosurveillance to evaluate the risk association between the use of antidiabetic thiazolidinediones, a class of PPARG agonists, and development of ONFH by referencing 9,638,296 patient records for individuals treated at Mayo Clinic. RESULTS A combined analysis of the discovery and validation cohorts revealed that seven SNPs were tightly clustered adjacent to the 3' end of PPARG, suggesting an association with the risk of ONFH (p = 1.58 x 10-5.50 x10). PPARG gene-level significance was achieved (p = 3.33 x 10) when all seven SNPs were considered. SNP rs980990 had the strongest association with the risk of ONFH (odds ratio [OR], 1.95; 95% CI, 1.46-2.59; p = 5.50 x 10).The seven identified SNPs were mapped to a region near the PPARG gene and fell in a highly conserved region consisting of several critical transcription factor binding sites. Nucleotide polymorphisms at these sites may compromise three-dimensional chromatin organization and alter PPARG 3' end interactions with its 5' promoter and transcription start site. Pharmacosurveillance identified that patients who were exposed to thiazolidinediones had an increased relative risk of developing ONFH of 5.6 (95% CI, 4.5-7.1). CONCLUSIONS We found that disruption of PPARG regulatory domains is linked to an increased risk of ONFH. Mechanistically, aberrant regulation of PPARG compromises musculoskeletal differentiation because this master regulator creates a proadipogenic and antiosteogenic state. Furthermore, PPARG alters steroid metabolism and vasculogenesis, processes that are inextricably linked with ONFH. Pharmacologically, predisposition to ONFH was further exposed with thiazolidinedione use, which upregulates the expression of PPARG and is known to alter bone metabolism. Collectively, these findings provide a foundation to perform confirmatory studies of our proposed mechanism in preclinical models to develop screening diagnostics and potential therapies in patients with limited options. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
Alcohol consumption has been established to be a major factor in the development and progress of cancer. Genetic polymorphisms of alcohol-metabolism genes result in differences between individuals in exposure to acetaldehyde, leading to possible carcinogenic effects. Arg47His (rs1229984 G > A) in ADH1B have been frequently studied for its potential effect on carcinogenesis. However, the findings are as yet inconclusive. To gain a more precise estimate of this potential association, we conducted a meta-analysis including 66 studies from 64 articles with 31999 cases and 50964 controls. The pooled results indicated that ADH1B Arg47His polymorphism is significantly associated with the decreased risk of overall cancer (homozygous model, odds ratio (OR) = 0.62, 95% confidence interval (CI) = 0.49–0.77; heterozygous model, OR = 0.71, 95% CI = 0.60–0.84; recessive model, OR = 0.83, 95% CI = 0.76–0.91; dominant model, OR = 0.62, 95% CI = 0.53–0.72; and allele comparison, OR = 0.82, 95% CI = 0.75–0.89). Stratified analysis by cancer type and ethnicity showed that a decreased risk was associated with esophageal cancer and head and neck cancer amongst Asians. In conclusion, our meta-analysis suggested that ADH1B Arg47His polymorphism was significantly associated with decreased overall cancer risk. These findings need further validation in large multicenter investigations.

Abstract
BACKGROUND Endothelial dysfunction has been identified as an etiologic factor for osteonecrosis of the femoral head (ONFH) and major adverse cardiovascular and cerebrovascular events (defined as major cardiovascular disease [CVD] and cerebrovascular accident [CVA]). However, the incidence of major adverse cardiovascular and cerebrovascular events in patients with nontraumatic ONFH and any association between the two diagnoses remain unclear. QUESTIONS/PURPOSES We compared a large cohort of patients with nontraumatic ONFH and a matched control group without this diagnosis and (1) examined the frequency and hazard ratio (HR) of major adverse cardiovascular and cerebrovascular events in both groups adjusted for age, sex, socioeconomic status, and associated comorbidities (which we defined as the adjusted HR), (2) determined whether any association of ONFH and major adverse cardiovascular and cerebrovascular events was stable after adjusting for confounding variables, and (3) compared the occurrence of major adverse cardiovascular and cerebrovascular events with time in both groups. METHODS A population-based cohort with a 14-year dataset period (1997-2010) from the Taiwan National Health Insurance Research Database was used for this retrospective study. The database includes a greater than 99.5% Asian population randomly selected from more than 23 million citizens and foreigners residing in Taiwan for longer than 6 months. A total of 1562 patients with nontraumatic ONFH were identified from a population of one million patients in the database after excluding initially concomitant diagnoses of major CVD and CVA. The comparison group (n = 15,620) without ONFH was analyzed in a one-to-10 ratio by matching the study cohort based on age, sex, income, and urbanization. RESULTS The patients with ONFH had a higher frequency of major adverse cardiovascular and cerebrovascular events than their counterparts without ONFH (19% versus 14%; p < 0.001). The patients with ONFH had 1.34- and 1.27-fold adjusted HRs for occurrence of major CVD and CVA as compared with the normal population (95% CI, 1.11-1.61, p = 0.002, and 95% CI, 1.09-1.47, p = 0.002, respectively). Sensitivity analysis showed a consistent association between ONFH and major adverse cardiovascular and cerebrovascular events after controlling for potentially relevant confounding variables such as hypertension and diabetes. After adjusting for potential confounders including surgery and medications, ONFH remained independently associated with major CVD (adjusted HR, 1.51, 95% CI 1.09-2.03, p = 0.026) and CVA (adjusted HR, 2.44, 95% CI 1.69-3.51, p < 0.001), apart from age older than 65 years and traditional atherosclerotic risk factors. The cumulative incidence of major adverse cardiovascular and cerebrovascular events also was higher in the ONFH group than the non-ONFH group (30.3% vs 23.1% at the end of followup, p < 0.001). CONCLUSIONS Patients with ONFH have a strong association with major adverse cardiovascular and cerebrovascular events as compared with the normal population, suggesting a potential common pathway involving endothelial dysfunction. In view of this association in the relatively young population with ONFH, it is important to closely monitor these patients, treat relevant comorbidities early, and investigate preventative measures for these major adverse events. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
PURPOSE Endothelial dysfunction is a risk factor for osteonecrosis of femoral head (ONFH) and venous thromboembolism (VTE) [defined as deep venous thrombosis (DVT) or pulmonary embolism (PE)]. However, the risk of unprovoked VTE in non-traumatic ONFH patients remains unclear. METHODS We investigated the relationship between ONFH and VTE using Taiwan National Health Insurance Research Database (NHIRD). Between 1997 and 2010, a total of 1514 non-traumatic ONFH patients were identified from 1,000,000 general populations after excluding initially concomitant diagnoses of DVT and PE, and subjects undergoing lower limb surgery within one year since enrollment. The comparison group (n = 15,140) without ONFH was set up by matching study cohort with age, gender, income and urbanization in a 1:10 ratio. Subjects diagnosed with VTE within one year after surgery were also excluded. RESULTS The patients with non-traumatic ONFH had significantly higher frequency of unprovoked VTE, including DVT, than general population (1.19 vs. 0.5%, p < 0.0007), whereas the frequency of PE was similar between these two groups (p = 0.4922). The cumulative incidence of VTE and DVT was also remarkably higher in the ONFH than non-ONFH group (all p < 0.001). After adjusting for age, gender, medications and comorbidities with multivariate analysis, the ONFH patients had a 2.3-fold increase in risk of DVT compared with non-ONFH counterparts (95% CI 1.28 to 4.13, p = 0.0053). Apart from ONFH, age > 65 years and hypertension were also identified as risk factors for DVT occurrence. CONCLUSIONS The incidence and risk of unprovoked VTE were significantly increased in the non-traumatic ONFH population.

Abstract
Background Common variants of multiple genes played a crucial role in osteonecrosis of the femoral head (ONFH) onset which was proved by many previous reports. We hypothesized that polymorphisms in NOS3, ABCB1 and IL23R were related to individual differences in alcohol sensitivity and the development of alcohol-induced ONFH. Methods In this case-control study, we evaluated 8 SNPs in three genes in the Chinese Han population including 355 male cases and 355 healthy male controls. These SNPs were genotyped by Sequenom MassARRAY RS1000. To identify their relationship with alcohol-induced ONFH susceptibility using χ2 test and genetic model analysis. Results We found an association with alcohol-induced ONFH susceptibility for 4 SNPs (rs743506, rs3918184, rs13233308 and rs6693831) in three genes after adjusted by age. The genotype “G/A” of rs743506 in NOS3 gene acts as a risk factor in genotype (P = 0.003), dominant (P = 0.048), recessive (P = 0.005) and additive model(P = 0.006); The genotype “T/C” of rs3918184 in NOS3 gene acts as a risk factor in genotype (P = 0.012) and recessive model (P = 0.009); The genotype “T/C” of rs13233308 in ABCB1 gene acts as a risk factor in genotype (P = 0.038) and additive model(P = 0.041); The genotype “T/C” of rs6693831 in IL23R gene acts as a protective factor in genotype model (P = 0.046). Conclusions This study provides evidence for three alcohol-induced ONFH susceptibility genes (NOS3, ABCB1 and IL23R) in Chinese males and polymorphisms of them may be associated with alcohol-induced ONFH risk.

Abstract
OBJECTIVE To examine recent time trends in the incidence of osteonecrosis (ON) in Denmark and to investigate different common comorbidities association with ON in a population-based setting. METHODS Using Danish medical databases, we included all patients with a first-time hospital diagnosis of ON during 1995-2012. Each ON case was matched with 10 randomly selected population control subjects from general population. For all participants, we obtained a complete hospital history of comorbidities included in the CharlsonComorbidity Index 5 years preceding the inclusion date. RESULTS 4107 ON cases and 41 063 controls were included. The incidence of ON increased from 3.9 in 1995 to 5.5 in 2012 per 100 000 inhabitants. Solid cancer was the most common comorbidity, associated with an adjusted OR (aOR) for ON of 2.0 (95% CI 1.7 to 2.2). For advanced metastatic cancer, leukaemia and lymphoma, aORs of ON were 3.4 (95% CI 2.5 to 4.5), 4.3 (95% CI 2.7 to 7.0) and 5.8 (95% CI 4.3 to 7.8), respectively. Among other chronic conditions, aORs were 3.5 (95% CI 3.0 to 4.1) for connective tissue diseases and 2.3 (95% CI 2.0 to 2.7) for chronic pulmonary diseases. aORs were also increased at 2.8 (95% CI 1.9 to 4.1) and 4.5 (95% CI 2.5 to 8.2) for mild and moderate-to-severe liver disease, respectively, and 4.2 (95% CI 3.4 to 5.2) for renal disease. CONCLUSION This large population-based study provides evidence for an increasing ON incidence in the general population and documents an association between several common comorbid conditions and risk of ON.

Abstract
Idiopathic osteonecrosis of the femoral head (IONFH) is an ischemic disorder that causes bone necrosis of the femoral head, resulting in hip joint dysfunction. IONFH is a polygenic disease and steroid and alcohol have already known to increase its risk; however, the mechanism of IONFH remains to be elucidated. We performed a genome-wide association study using ~60,000 subjects and found two novel loci on chromosome 20q12 and 12q24. Big data analyses identified LINC01370 as a candidate susceptibility gene in the 20q12 locus. Stratified analysis by IONFH risk factors suggested that the 12q24 locus was associated with IONFH through drinking capacity. Our findings would shed new light on pathophysiology of IONFH.

Avascular Necrosis of Femoral Head: A Metabolomic, Biophysical, Biochemical, Electron Microscopic and Histopathological Characterization. Sci Rep 2017; 7:10721. [PMID: 28878383 PMCID: PMC5587540 DOI: 10.1038/s41598-017-10817-w] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2016] [Accepted: 08/14/2017] [Indexed: 12/29/2022] Open
Abstract
Avascular necrosis of the femur head (AVNFH) is a debilitating disease caused due to the use of alcohol, steroids, following trauma or unclear (idiopathic) etiology, affecting mostly the middle aged population. Clinically AVNFH is associated with impaired blood supply to the femoral head resulting in bone necrosis and collapse. Although Homocysteine (HC) has been implicated in AVNFH, levels of homocysteine and its associated pathway metabolites have not been characterized. We demonstrate elevated levels of homocysteine and concomitantly reduced levels of vitamins B6 and B12, in plasma of AVNFH patients. AVNFH patients also had elevated blood levels of sodium and creatinine, and reduced levels of random glucose and haemoglobin. Biophysical and ultrastructural analysis of AVNFH bone revealed increased remodelling and reduced bone mineral density portrayed by increased carbonate to phosphate ratio and decreased Phosphate to amide ratio together with disrupted trabeculae, loss of osteocytes, presence of calcified marrow, and elevated expression of osteocalcin in the osteoblasts localized in necrotic regions. Taken together, our studies for the first time characterize the metabolomic, pathophysiological and morphometric changes associated with AVNFH providing insights for development of new markers and therapeutic strategies for this debilitating disorder.

Abstract
Younger patients are affected more often by osteonecrosis than by osteoarthritis, and osteonecrosis has significantly greater long-term morbidity. Corticosteroids are the most common cause of nontraumatic osteonecrosis. The femoral head is the most common site of osteonecrosis. In rare instances, osteonecrosis of the jaw has been associated with bisphosphonate exposure. This phenomenon is more common with repeated intravenous infusions of bisphosphonates. Case reports of osteonecrosis of the jaw in association with other medications, such as denosumab, have been reported. The final common pathway in the pathogenesis of osteonecrosis is disruption of blood supply to a segment of bone. Abnormalities in lipid metabolism, bone homeostasis, regulation of apoptosis, coagulopathies, innate immunity, and oxidative stress may play a role in the pathogenesis of osteonecrosis. Epigenetics may alter the predisposition to develop osteonecrosis. MRI is currently the optimal test for early diagnosis and identification of the extent of osteonecrosis. Nonsurgical treatment of osteonecrosis does not change the natural history of the disease. Although surgical treatment of femoral head osteonecrosis has many variations, most symptomatic patients eventually require total hip arthroplasty. Knowledge of risk factors and early detection are crucial to the successful management of osteonecrosis. Because of the lack of successful treatment options, new modes of management focus on the prevention of osteonecrosis.

Abstract
Musculoskeletal problems in patients with liver disease are common; however, they are not so well described in the literature. Therefore, there is a need to collate information on these disorders, as their incidence is on a constant rise and some of these pathologies can severely debilitate the patient's quality of life. These disorders are parietal wall varices with or without bleeding, spontaneous intramuscular haematoma (e.g. rectus sheath), abdominal wall hernia, anasarca, hepatic osteodystrophy, septic arthritis, osteomyelitis, necrotizing fasciitis, osseous metastases from hepatocellular carcinoma etc. While portal hypertension plays a key role in disorders, in others, dysregulation of the coagulation system or a compromised immune system are responsible. Imaging plays an essential role in the assessment of these complications and awareness of these musculoskeletal manifestations is vital for establishing a timely diagnosis and planning of appropriate therapy, as these disorders can significantly impact the morbidity and mortality and also influence candidacy for liver transplantation. We herein comprehensively appraise various musculoskeletal complications associated with chronic liver disease/liver cirrhosis especially from an imaging perspective which, to the best of our knowledge, have not been collectively described in English literature.

Abstract
PURPOSE The aldehyde dehydrogenase 2 (ALDH2) gene has been implicated in the development of alcoholic liver cirrhosis (ALC) in East Asians. However, the results are inconsistent. In this study, a meta-analysis was performed to assess the associations between the ALDH2 polymorphism and the risk of ALC. MATERIALS AND METHODS Relevant studies were retrieved by searching PubMed, Web of Science, CNKI, Wanfang and Veipu databases up to January 10, 2015. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using either the fixed- or random effects model. RESULTS A total of twelve case-control studies included 1003 cases and 2011 controls were included. Overall, the ALDH2 polymorphism was associated with a decreased risk of ALC (*1/*2 vs. *1/*1: OR=0.78, 95% CI: 0.61-0.99). However, in stratification analysis by country, we failed to detect any association among Chinese, Korean or Japanese populations. CONCLUSION The pooled evidence suggests that ALDH2 polymorphism may be an important protective factor for ALC in East Asians.

Abstract
Osteonecrosis, also termed aseptic necrosis, is the cellular death of bone components due to interruption of the blood supply. Glucocorticoid (GC) therapy is a common non-traumatic cause of osteonecrosis. However, the mechanism by which GCs induce osteonecrosis remains to be elucidated. The aim of the present study was to investigate the effects of GCs on osteoclast and osteoblast differentiation and function in a GC-induced osteonecrosis mouse model. BALB/c male mice (n=40; 4-weeks-old) were treated with dexamethasone and asparaginase for 8 weeks. The control group (n=20) was administered normal saline. The results demonstrated that the GC-treated group had a lower mean weight compared with the control group. Morphologically, 16/37 (43%) mice demonstrated significant osteonecrotic lesions in the GC-treated group. However, osteonecrotic lesions were not observed in the mice of the control group. Furthermore, immunohistochemistry demonstrated that the GC-treated group had a higher level of osteoprotegerin compared with the control group, without any change in the expression of receptor activator of nuclear factor-κB ligand. In addition, tartarate-resistant acid-phosphatase staining demonstrated significantly decreased osteoclasts in the areas of bone destruction in the GCs-treated group. Furthermore, the present study demonstrated that GCs increased expression levels of osterix and osteocalcin, and decreased expression of matrix metallopeptidase-9 to regulate the differentiation and function of osteoblasts and osteoclasts. The results of the present study suggested that GCs influence bone remolding resulting in decreased osteoclasts formation/differentiation. Therefore, regulating the differentiation and activity of the osteoclasts may be beneficial to the control and treatment of osteonecrosis.

Abstract
BACKGROUND Variation in genes involved in alcohol metabolism is associated with drinking patterns worldwide. We compared variation in these genes among the Inuit with published results from the general population of Denmark and, due to the Asian ancestry of the Inuit, with Han Chinese. We analyzed the association between gene variations and drinking patterns among the Inuit. METHODS We genotyped 4162 Inuit participants from two population health surveys. Information on drinking patterns was available for 3560. Seven single nucleotide polymorphisms (SNPs) were examined: ADH1B arg48his, ADH1C ile350val, ADH1C arg272gln, ALDH2 glu504lys, ALDH2 5'-UTR A-357G, ALDH1B1 ala86val and ALDH1B1 arg107leu. RESULTS The allele distribution differed significantly between Inuit and the general population of Denmark. A protective effect on heavy drinking was found for the TT genotype of the ALDH1B1 arg107leu SNP (OR=0.59; 95% CI 0.37-0.92), present in 3% of pure Inuit and 37% of Danes. The ADH1C GG genotype was associated with heavy drinking and a positive CAGE test (OR 1.34; 95% CI 1.05-1.72). It was present in 27% of Inuit and 18% of Danes. The Asian genotype pattern with a high frequency of the ADH1B A allele and an ALDH2 gene coding for an inactive enzyme was not present in Greenland. CONCLUSIONS ADH1C and ALDH1B1 arg107leu SNPs play a role in the shaping of drinking patterns among the Inuit in Greenland. A low frequency of the ALDH1B1 arg107leu TT genotype compared with the general population in Denmark deserves further study. This genotype was protective of heavy drinking among the Inuit.

Abstract
Objectives Necrosis of femoral head is a severe pathological state with multiple etiologies. This study investigated the association of the 27-bp repeat polymorphism in intron 4 and G894T polymorphism in exon 7 of the endothelial nitric oxide synthase (eNOS) gene with the pathogenesis of avascular necrosis of femoral head (ANFH). Methods A total of 125 non-traumatic ANFH patients and 126 healthy controls were recruited for this study. The 27-bp repeat polymorphisms in intron 4 were analyzed by polymerase chain reaction (PCR) and sequencing. The G894T polymorphisms in exon 7 were analyzed by PCR– restriction fragment length polymorphism (PCR-RFLP) analysis. Results All alleles were observed in non-traumatic ANFH patients and control subjects. Both ANFH patients and idiopathic subgroup of ANFH patients showed higher frequency of the 4a/b genotype than controls (p = 0.001 and p = 0.020, respectively). Significantly higher frequency of G/T genotype was observed in ANFH patients and idiopathic subgroup of ANFH patients compared to controls (p = 0.009 and p = 0.035, respectively). Conclusion eNOS gene polymorphisms may be a risk factor for ANFH. The 27-bp repeat polymorphism in intron 4, G894T polymorphism in exon 7, and subsequently reduced eNOS activity may be involved in the etiology of idiopathic ANFH.

Abstract
The aim of this paper is to describe our surgical procedure for the treatment of osteonecrosis of the femoral head using a minimally invasive technique. We have limited the use of this procedure for patients with pre-collapse osteonecrosis of the femoral head (Ficat Stage I or II). To treat osteonecrosis of the femoral head at our institution we currently use a combination of outpatient, minimally invasive iliac crest bone marrow aspirations and blood draw combined with decompressions of the femoral head. Following the decompression of the femoral head, adult mesenchymal stem cells obtained from the iliac crest and platelet rich plasma are injected into the area of osteonecrosis. Patients are then discharged from the hospital using crutches to assist with ambulation. This novel technique was utilized on 77 hips. Sixteen hips (21%) progressed to further stages of osteonecrosis, ultimately requiring total hip replacement. Significant pain relief was reported in 86% of patients (n = 60), while the rest of patients reported little or no pain relief. There were no significant complications in any patient. We found that the use of a minimally invasive decompression augmented with concentrated bone marrow and platelet rich plasma resulted in significant pain relief and halted the progression of disease in a majority of patients.

Abstract
AIM To explore the feasibility of allogeneic mesenchymal stem cells (MSCs) transplanted intravenously for angiogenesis and bone repair in a rabbit model of avascular necrosis of femoral head (ANFH). MATERIALS AND METHODS Forty-five rabbits were randomized into three groups: a blank control group (without treatment), a necrotic control group (ANFH induced but without therapy), and an MSC transplantation group (ANFH induced and treated with MSC transplantation). The biopsies, blood sampling, and imaging examinations were performed on each animal at different time points (2, 4, and 6 wk). To monitor angiogenesis and bone repair progress, examinations included real-time polymerase chain reaction, Western blot analysis, x-ray, computed tomography, Masson trichrome staining, picrosirius red staining, and immunohistochemical staining. RESULTS Necrosis and bone collapse were observed in bilateral femoral heads of necrotic rabbits of the necrotic control group, whereas the femoral head morphology was generally restored in the MSC transplantation group. The mRNA levels of Cbfa1, BMP, VEGF, and OPN in bone tissue were significantly higher in the MSC transplantation group than in the necrotic control group. In addition, the total protein amount of Cbfa1 in the MSC transplantation group was also significantly higher than that in the necrotic control group (P < 0.05). CONCLUSION Intravenous transplantation of allogeneic MSCs can promote vascular and bone regeneration in the necrotic region of the femoral head in a rabbit model of ANFH. The results of our study suggest that the intravenous transplantation of MSCs could be a potential and minimally invasive treatment option for ANFH patients.

Abstract
Nontraumatic osteonecrosis continues to be a challenging problem causing debilitating major joint diseases. The etiology is multifactorial, but steroid- and alcohol-induced osteonecrosis contribute to more than two thirds of all cases with genetic risk factors playing an important role in many other cases, especially when they contribute to hypercoagulable states. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade that have given us a clearer picture of the pathogenesis of nontraumatic osteonecrosis of the femoral head. Progression to end stage osteonecrosis of the femoral head appears to be related to four main factors: interactions involving the differentiation pathway of osteoprogenitor cells that promote adipogenesis, decreased angiogenesis, direct suppression of osteogenic gene expression and proliferation of bone marrow stem cells, and genetic anomalies or other diseases that promote hypercoagulable states.

Abstract
From the joint registry of 2831 primary total hip arthroplasties (2351 patients) performed between 1998 and 2003, we identified 15 patients (16 hips) who had a documented history of substance abuse disorders at the time of the index surgery. The patients included 13 men (14 hips) and 2 women (2 hips), with the mean age of 49 years (range, 29-65 years). On the basis of the criteria specified in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, 13 patients had alcohol abuse disorders, 1 had amphetamine abuse disorder, and 1 had heroin abuse disorder. We found high rates of postoperative substance withdrawal delirium and psychosis (46%), late complication (25%), and lost to follow-up (27%) in these patients. Because patients with substance abuse disorders have unexpected perioperative psychotic episodes, poor compliance, and a tendency to not follow medical advice after surgery and show early discontinuation of follow-up, we suggest that surgeons should work with other medical professionals and carefully perform total hip arthroplasty in such patients.

Abstract
Alcohol is oxidized to acetaldehyde, which in turn is oxidized to acetate. The aldehyde dehydrogenase 2 gene (ALDH2) is the most important gene responsible for acetaldehyde metabolism. Individuals heterozygous or homozygous for the lys (A or *2) allele at the single nucleotide polymorphism (SNP) glu504lys (rs671) of ALDH2 have greatly reduced ability to metabolize acetaldehyde, which greatly decreases their risk for alcohol dependence (AD). Case-control studies have shown association between this SNP and alcohol dependence as well as alcohol-induced liver disease. However, some studies have produced insignificant results. Using cumulative data from the past 20 years predominately from Asian populations (from both English and Chinese publications), this meta-analysis sought to examine and update whether the aggregate data provide new evidence of statistical significance for the proposed association. Our results (9,678 cases and 7,331 controls from 53 studies) support a strong association of alcohol abuse and dependence, with allelic P value of 3 × 10(-56) and OR of 0.23 (0.2, 0.28) under the random effects model. The dominant model (lys-lys + lys-glu vs. glu-glu) also showed strong association with P value of 1 × 10(-44) and OR of 0.22 (0.18, 0.27). When stricter criteria and various sub-group analyses were applied, the association remained strong (for example, OR = 0.23 (0.18, 0.3) and P = 2 × 10(-28) for the alcoholic patients with alcoholic liver disease, cirrhosis, or pancreatitis). These findings provide confirmation of the involvement of the human ALDH2 gene in the pathogenesis of AD as well as alcohol-induced medical illnesses in East-Asians.

[PMID: 21497796 PMCID: PMC3142297 DOI: 10.1016/j.biopsych.2011.02.024] [Citation(s) in RCA: 128] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2011] [Revised: 02/21/2011] [Accepted: 02/21/2011] [Indexed: 12/18/2022]
Abstract
BACKGROUND The alcohol dehydrogenase 1B gene (ADH1B) is hypothesized to affect predisposition to alcohol dependence (AD) and abuse. A variant of the ADH1B gene (rs1229984 or Arg48His; previously referred to as Arg [*1] and His [*1]) has been reported to be associated with reduced rates of alcohol and drug dependence. Different studies have produced inconclusive results regarding association between rs1229984 (or rs2066702) and substance dependence. METHODS Using the cumulative association study literature from the past 21 years from both English- and Chinese-language publications, this meta-analysis seeks to clarify the contradictory findings and to examine whether the aggregate data provide new evidence of significant association. RESULTS The results, based on a large sample size (9638 cases and 9517 controls), suggested strong associations with alcohol dependence and abuse as well as alcohol-induced liver diseases, with an allelic (Arg vs. His) p value being 1 × 10(-36) and odds ratio (OR) (95% confidence intervals [CI]) 2.06 (1.84-2.31) under the random effects model. The dominant and recessive models produced larger ORs of 2.17 and 3.05, respectively. When more stringent criteria and subgroup analyses were imposed, the associations remained consistent and were strongest in various Asian groups (allelic p = 7 × 10(-42) and OR (95% CI) = 2.24 [1.99-2.51] with ORs of 2.16 and 4.11 for dominant and recessive models, respectively). CONCLUSIONS Our findings provide further strong evidence for the involvement of the ADH1B gene in the pathogenesis of alcohol dependence and abuse as well as for some alcohol-induced medical diseases in the multiple ethnic populations--in particular, certain Asian populations.

Abstract
BACKGROUND Osteonecrosis (ON) of the femoral head is a devastating disease affecting young patients at their most productive age, causing major socioeconomic burdens. ON is associated with various etiologic factors, and the pathogenesis of the disease is unknown. Most investigators believe the disease is the result of secondary microvascular compromise with subsequent bone and marrow cell death and defective bone repair. QUESTIONS/HYPOTHESES We hypothesize that local delivery of vascular endothelial growth factor (VEGF) and bone morphogenetic protein-6 (BMP-6), which induces angiogenesis and osteogenesis respectively, will reverse the disease process and provide a treatment for precollapse ON. METHOD OF STUDY We will use genetically engineered bone marrow stem cells, carrying VEGF and BMP-6 genes, to enhance angiogenesis and osteogenesis in necrotic bone of an animal model, by local delivery of growth factor in addition to the bone-forming property of the stem cells. The participation, localization, and fate of the stem cells in the repair process will be evaluated by tracing marker-gene product. Osteogenesis and angiogenesis will be assessed using high-resolution xray CT and immunohistomorphometry quantitatively. Mechanical properties of the repair tissue will be determined using an indentation test of the femoral head. SIGNIFICANCE We envision that a deliverable or injectable bone graft substitute containing engineered stem cells and therapeutic growth factors will be developed through this proposed study and will provide a much needed treatment for ON.

Abstract
In an attempt to observe the genetic traits of avascular necrosis of the femoral head, we analyzed the genomic alterations in blood samples of 18 patients with avascular necrosis of the femoral head (9 idiopathic and 9 alcoholic cases) using the array comparative genomic hybridization method and real-time polymerase chain reaction. Several candidate genes were identified that may induce avascular necrosis of the femoral head, and we investigated their role in the pathomechanism of osteonecrosis of bone. The frequency of each candidate gene over all the categories of avascular necrosis of the femoral head was also calculated by real-time polymerase chain reaction. The highest frequency specific genes in each category were FLJ40296, CYP27C1, and CTDP1. FLJ40296 and CYP27C1 had the highest frequency (55.6%) in the idiopathic category. FLJ40296 had a high frequency (44.4%) in the alcoholic category, but CYP27C1 had a relatively low frequency (33.3%) in the alcoholic category. However, CTDP1 showed a significantly high frequency (55.6%) in the alcoholic category and a low frequency (22.2%) in the idiopathic category. Although we statistically analyzed the frequency of each gene with Fisher's exact test, we could not prove statistical significance due to the small number of samples. Further studies are needed with larger sample numbers. If the causal genes of avascular necrosis of the femoral head are found, they may be used for early detection, prognosis prediction, and genomic treatment of avascular necrosis of the femoral head in the future.

Abstract
This study was designed to evaluate the effects of the combined treatment with an anti-coagulant (enoxaparin) agent and a lipid-lowering agent (lovastatin) on prevention or decrease in the occurrence of steroid-induced osteonecrosis in rabbits. A total of 112 rabbits, which were injected intramuscularly with 20 mg/kg of methylprednisolone acetate were divided into four groups and treated as follows: one group received enoxaparin combined with lovastatin (EL; n = 30), another received enoxaparin alone (EA; n = 28), another received lovastatin alone (LA; n = 28) and the last received no treatment (non-prophylactic; NP, n = 26). Haematological examination for serum lipid levels and prothrombin time was carried out and both femora and humeri were examined histopathologically for the presence of osteonecrosis (ON) before injection and at 2, 4, 8 and 12 weeks after the injection. The incidence of ON in the EL group (15%) was significantly lower than that observed in the NP group (68%). The incidence in the EA and LA groups was also significantly lower than that in the NP group (31%, 35%vs. 68%). The fat cell sizes of the bone marrow in both EL (46.49 +/- 1.27 microm) and LA (50.8 +/- 2.31 microm) groups were lower than in the NP group (59.89 +/- 6.33 microm). The prothrombin time was prolonged and plasma lipid levels were reduced in the EL group during the study. Combination treatment with an anti-coagulant agent and a lipid-lowering agent can reduce the incidence of steroid-induced ON in rabbits. Future evaluation in clinical practice is necessary.

Abstract
Intensive bone cell apoptosis contributes to osteonecrosis of femoral head (ONFH). Dickkopf-1 (DKK1) reportedly mediates various types of skeletal disorders. This study investigated whether DKK1 was linked to the occurrence of ONFH. Thirty-nine patients with various stages of ONFH were recruited. Bone specimens were harvested from 34 ONFH patients underwent hip arthroplasty, and from 10 femoral neck fracture patients. Bad, Bcl2 TNFalpha, DKK1, Wnt3a, LRP5, and Axin1 expressions were analyzed by quantitative RT-PCR and ELISA. Apoptotic cells were assayed using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end-labelling (TUNEL). Primary bone-marrow mesenchymal cells were treated with DKK1 RNA interference and recombinant DKK1 protein. ONFH patients with the histories of being administrated corticosteroids and excessive alcohol consumption had significantly higher Bad and DKK1 mRNA expressions in bone tissue and DKK1 abundances in serum than femoral neck fracture patients. Bone cells adjacent to osteonecrotic bone displayed strong DKK1 immunoreactivity and TUNEL staining. Increased DKK1 expression in bone tissue and serum correlated with Bad expression and TUNEL staining. Serum DKK1 abundance correlated with the severity of ONFH. The DKK1 RNA interference and recombinant DKK1 protein regulated Bad expression and apoptosis of primary bone-marrow mesenchymal cells. Knock down of DKK1 reduced dexamethasone-induced apoptosis of mesenchymal cells. Taken together, promoted DKK1 expression was associated with bone cell apoptosis in the occurrence of ONFH patients with the histories of corticosteroid and alcohol intake and progression of ONFH. DKK1 expression in injured tissue provides new insight into ONFH pathogenesis.

Abstract
BACKGROUND AND PURPOSE Extracorporeal shockwave therapy (ESWT) and alendronate are reported effective in early osteonecrosis of the femoral head (ONFH). We hypothesized that joint effects of ESWT and alendronate may produce superior results. This prospective study compared the results of ESWT and alendronate with that of ESWT without alendronate in early ONFH. PATIENTS AND METHODS Forty-eight patients with 60 hips were randomly divided into tow groups. There were 25 patients with 30 hips in group A and 23 patients with 30 hips in group B. Both groups showed similar demographic characteristics. All patients were treated with 6,000 impulses of ESWT at 28 KV (equivalent to 0.62 mJ/mm(2)) to the affected hip as a single session. Patients in group B also received alendronate 70 mg per week for 1 year, whereas patients in group A did not. The evaluations included clinical assessment, radiograph and MR image of the affected hip. Both groups were compared statistically using paired t, Mann-Whitney and Chi square tests with statistical significance at P < 0.05. The primary end point is the need for total hip arthroplasty (THA). The secondary end point is the improvement in pain and function of the hip. The third end point is the progression or regression of the lesion on image study. RESULTS The overall clinical outcomes were improved in 83%, unchanged in 7% and worsened in 10% for group A; and improved in 77%, unchanged in 13% and worsened in 10% for group B. THA was performed in 10% of group A and 10% of group B (P = 1.000). Significant improvements in pain and function of the hip were noted in both groups (P < 0.001), however, the differences between the two groups were not significant (P = 0.400, 0.313). On MR images, the lesions showed progression in 10%, regression in 47% and unchanged in 43% in group A, and progression in 7%, regression in 53% and unchanged in 40% in group B (P = 0.830). CONCLUSION ESWT and alendronate produced comparable result as compared with ESWT without alendronate in early ONFH. It appears that ESWT is effective with or without the concurrent use of alendronate. The joint effects of alendronate over ESWT in early ONFH are not realized in short-term.

Abstract
Osteonecrosis of the femoral head (ONFH) is a skeletal disorder characterized by ischemic deterioration, bone marrow edema and eventually femoral head collapse. The systemic regulation of ONFH in adult patients has not been examined. Serum proteomic is an innovative tool that potentially detects simultaneous expressions of serum proteins in pathological contexts. We compared the serum proteome profiles of 11 adult patients with ONFH (3 females and 8 males) and 11 healthy volunteers (3 females and 8 males). The proteins in the aliquots of sera were subjected to isoelectric focusing, two-dimensional gel electrophoresis and silver staining. The protein spots were matched and quantified using an imaging analysis system. The differentially expressed protein spots were subjected to in-gel trypsin digestion. The peptide mass fingerprints were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF/TOF) and a bioinformation search. We found that ONFH patients showed significantly higher abundances of kininogen 1 variant, complement factor C3 precursor, and complement factor H and lower levels of antithrombin III chain B, apolipoprotein A--IV precursor, and gelsolin isoform alpha precursor. These proteins of interest were reported to modulate thrombotic/fibrinolytic reactions, oxidative stress, vessel injury, tissue necrosis or cell apoptosis in several tissue types under pathological contexts. Taken together, the occurrence of ONFH was associated with various serum protein expressions. Our high--throughput serum proteomic findings indicated that multiple pathological reactions presumably occurred in ONFH.

Abstract
We hypothesized that inherited thrombophilia and hypofibrinolysis were risk factors for osteonecrosis of the femoral head. We compared measures of thrombophilia and hypofibrinolysis in referred new adult patients with idiopathic osteonecrosis (n = 71) or secondary osteonecrosis (n = 62) with the same measures in sex- and race-matched healthy control subjects. Heritable thrombophilic Factor VIII and hypofibrinolytic Lp(a) were more frequently high in the 71 patients with idiopathic osteonecrosis than in control subjects. High Factor VIII, Factor V Leiden heterozygosity, and resistance to activated protein C, all heritable thrombophilias, were more frequently present in the 62 patients with secondary osteonecrosis than in control subjects. Our data suggest inherited thrombophilia and hypofibrinolysis are risk factors for both idiopathic and secondary osteonecrosis of the head of the femur.

Abstract
Variations in the UDP-glucuronosyltransferase (UGT) 1A7 gene have been found to be related to the development of hepatocellular carcinoma (HCC). Since the pathogenesis of liver cirrhosis is not dissimilar to that of HCC, we hypothesized that UGT1A7 genetic polymorphisms may be associated with liver cirrhosis. PCR-restriction fragment length polymorphism was utilized to determine UGT for 1A7 genotypes for the 159 patients with liver cirrhosis and 263 gender/age matched controls. Simple logistic regression analysis revealed that significant risk factors for liver cirrhosis were (1) hepatitis B virus (HBV) infection, (2) hepatitis C virus (HCV) infection, (3) HBV infection plus HCV infection and (4) low-activity UGT1A7 genotypes. The results of further multivariate logistic regression confirmed these associations. Interaction of low-activity UGT1A7 genotypes and HBV (or HCV) infection produced an additive effect upon the risk for the development of liver cirrhosis [observed odds ratio (OR) (54.59) greater than the expected OR (18.05)]. UGT1A7 low/low genotype was also related to advanced liver cirrhosis (Child-Pugh classes C and/or B) (OR=7.50, P=0.009). This study demonstrates the novel findings that carriage of low-activity UGT1A7 genotypes represents a risk factor for the development and functional severity of liver cirrhosis.

Abstract
Recent introduction of several commercial Kudzu root (Pueraria lobata) containing hangover remedies has occurred in western countries. The available data is reviewed to assess if there are any potential concerns in relationship to the development of neoplasm if these products are used chronically. The herb Pueraria has two components that are used as traditional therapies; Pueraria lobata, the root based herb and Pueraria flos, the flower based herb. Both of these herbal components have different traditional claims and constituents. Pueraria flos, which enhances acetaldehyde removal, is the traditional hangover remedy. Conversely, Pueraria lobata is a known inhibitor of mitochondrial aldehyde dehydrogenase (ALDH2) and increases acetaldehyde. Pueraria lobata is being investigated for use as an aversion therapy for alcoholics due to these characteristics. Pueraria lobata is not a traditional hangover therapy yet has been accepted as the registered active component in many of these hangover products. The risk of development of acetaldehyde pathology, including neoplasms, is associated with genetic polymorphism with enhanced alcohol dehydrogenase (ADH) or reduced ALDH activity leading to increased acetaldehyde levels in the tissues. The chronic usage of Pueraria lobata at times of high ethanol consumption, such as in hangover remedies, may predispose subjects to an increased risk of acetaldehyde-related neoplasm and pathology. The guidelines for Disulfiram, an ALDH2 inhibitor, provide a set of guidelines for use with the herb Pueraria lobata. Pueraria lobata appears to be an inappropriate herb for use in herbal hangover remedies as it is an inhibitor of ALDH2. The recommendations for its use should be similar to those for the ALDH2 inhibitor, Disulfiram.

Abstract
Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

Abstract
Fetal alcohol syndrome (FAS), 1 of the most common developmental disabilities in the United States, occurs at a rate of 0.5-2.0:1000 live births. Animal model, family, and twin studies suggest a genetic component to FAS susceptibility. Alcohol dehydrogenases (ADHs) catalyze the rate-limiting step in alcohol metabolism. Studies of genetic associations with FAS have focused on the alcohol dehydrogenase 1B (ADH1B) gene, comparing mothers and children with the alleles ADH1B*2 or ADH1B*3, associated with faster ethanol metabolism, with those homozygous for ADH1B*1. While most studies have found a protective effect for genotypes containing ADH1B*2 or ADH1B*3, results have been conflicting, and further investigation into the association between the ADH1B genotype and FAS is needed. Whether increased alcohol intake accounts for the elevated risk reported for the ADH1B*1/ADH1B*1 genotype should be addressed, and future studies would benefit from consistent case definitions, enhanced exposure measurements, larger sample sizes, and careful study design.

Abstract
Avascular necrosis of bone (AVN) occurs as two main variants, local and systemic. Local AVN is usually caused by trauma or microtrauma; examples include primary osteonecrosis of the medial condyle, vertebral osteonecrosis, necrosis after meniscectomy, and osteonecrosis of the mandible or small bones. Systemic AVN manifests as epiphyseal necrosis or bone infarction, which is often multifocal. Little is known about the factors that trigger AVN. One possible mechanism is intraluminal obliteration of blood vessels by microscopic fat emboli, sickle cells, nitrogen bubbles (caisson disease), or focal clotting due to procoagulant abnormalities. Extraluminal obliteration may result from elevated marrow pressure or increased marrow fat. Cytotoxicity and genetic factors may be involved also. Many factors are probably capable of inducing AVN, and combinations of factors may be required, although the final mechanism is always critical ischemia. The natural history of AVN is better understood than the early triggering factors. AVN becomes detectable 1-6 months after exposure to an easily identifiable risk factor such as high-dose glucocorticoid therapy or femoral neck fracture. Later on, AVN is uncommon even when the patient remains exposed to the risk factor. The turning point in the natural history of AVN is subchondral plate fracture, which leads to collapse of the necrotic segment of the epiphysis, usually within the first 2 years. The risk of collapse depends chiefly on the initial size and location of the necrotic segment, which can be determined accurately by magnetic resonance imaging (MRI). This natural history has obvious clinical implications.

Abstract
The etiology of osteonecrosis of the hip may have a genetic basis. The interaction between certain risk factors and a genetic predisposition may determine whether this disease will develop in a particular individual. The rationale for use of joint-sparing procedures in the treatment of this disease is based on radiographic measurements and findings with other imaging modalities. Early diagnosis and intervention prior to collapse of the femoral head is key to a successful outcome of joint-preserving procedures. The results of joint-preserving procedures are less satisfactory than the results of total hip arthroplasty for femoral heads that have already collapsed. New pharmacological measures as well as the use of growth and differentiation factors for the prevention and treatment of this disease may eventually alter our treatment approach, but it is necessary to await results of clinical research with long-term follow-up of these patients.
