Objective To explore the clinical significance of the inferior displacement sign on the initial anterioposterior (AP) view X-ray for fractures of humeral greater tuberosity.Methods This study retrospectively analyzed the imaging and clinical data of 24 patients with isolated fracture of humeral greater tuberosity who had sought medical treatment during the period from January 2008 to June 2015.They were 10 males and 14 females,with an average age of 54 years (from 19 to 68 years).Laterality:8 left sides and 16 right sides.The AP view X-ray films of the 24 patients present the inferior displacement sign defined as the inferior cortical margin of the greater tuberosity overlapping the proximal humeral shaft on the initial AP view.The patients received further CT examination to determine the displacement direction and whether the humeral neck fracture was complicated.Results A slight displacement of humeral anatomic neck fracture was shown on the initial AP view X-ray in 10 patients.Further CT examination revealed that humeral anatomic neck fracture was confirmed in 23 patients,the greater tuberosity was displaced posteriorly in 22 patients and posteroinferiorly in 2 patients.Radiographic measurements showed:the mean posterior displacement was 10.5 ±4.5 mm;the displacement between the humeral head and the humeral shaft was 2.5 ± 1.5 mm;the neck shaft angle was 147.2° ± 9.2°;the distance between the humeral head and greater tuberosity was 10.8 ± 3.4 mm;the overlap between the inferior edge of greater tuberosity and the upper edge of lateral humeral shaft was 12.5±5.9 mm.Pearson correlation analysis showed no correlation between the overlap and the head-tuberosity distance (P > 0.05),but a significant correlation between the overlap and the neck-shaft angle (P < 0.05).Conclusions The inferior displacement sign on the initial AP view X-ray is actually the overlap of posterior displaced greater tuberosity fracture shown on the X-ray.The posterior displaced greater tuberosity fracture complicated with slight displaced anatomic neck fracture is a presentation of the valgus impacted fracture of the proximal humerus.The inferior displacement sign in the fracture of humeral greater tuberosity can highly suggest the presence of occult or slight displacement of the humeral anatomic neck fracture.

3.Expression and clinical significance of HA117 in adults with acute leukemia
Journal of International Oncology 2011;38(8):636-639
Objective To investigate the expression of HA117 in bone marrow mononuclear cells (BMMNCs) of acute leukemia patients, and its correlation with multidrug resistance( MDR), as well as its correlation with antigens presentation and its clinical significance. Methods HA117 gene expressions in 36 patients with acute myeloid leukemia (AML) and 14 patients with acute lymphocytic leukemia (ALL),10 patients with idiopathic thromnocytopenic purpura (ITP) were tested by using reverse transcriptase polymerase chain reaction (RT-PCR) technique. Thirty bone marrow specimens of AML patients at different phase were selected, and immunophenotypes were assayed by flow cytometry. ResultsThere was no significant difference ( P > 0.05 ) in HA117 gene expression between ALL (78.57%) and A ML (72.22%). The expressions of HA117 gene in both ALL and AML were significantly higher than in ITP patients ( P < 0.05 ). The HA117 gene was expressed in 75.00% of the initially diagnosed patients and 77.78% of the remission patients and 69.23% of the nonremission patients, all of them had higher expression than the patients with ITP, but there was no significant difference among the three groups. There were 47.06% and 87.88% with HA117 gene expressioned in non-resistance group and resistance group respectively, and the difference between the two groups was significant(P=0.005). HA117 had positively correlation with CD11b(OR =0.59, P=0. 001 ),CD33(OR=0.704, P=0. 000) expression in 30 patients of AML, and had negative correlation with MPO (OR=-0.611, P=0.001). ConclusionHA117 gene overexpression is significantly associated with the clinical resistance. It may also be associated with MDR of acute leukemia. HA117 gene can be used as an important indicator for investigating clinical MDR and predicting prognosis of acute Ieukemia patients. HA1 17 is closely related to CD11b, CD33, MPO expression in AML, and they can be used as biomarkers for evaluating therapy efficacy in AML.

10.Biological Effects of HBV X Protein on Hepatocellular Carcinogenesis in Association with Cellular Factors
Virologica Sinica 2008;23(2):146-151
The X protein (HBx) of Human hepatitis B virus (HBV) acts as an indirect transcriptional transactivator to regulate the expression of many viral and cellular genes, as well as playing a critical role in pathogenesis and the development of Hepatocellular carcinoma (HCC). Here we described the biological effects of HBx in association with four cellular factors, including inflammatory factors (COX-2 and iNOS), oncoprotein (Ras), and a newly identified tumor suppressor (YueF). The characteristics of these effectors, which might be associated with hepatocellular carcinoma, are also discussed.
