OBJECTIVE:To evaluate the curative efficacy of granulocyte macrophage colony stimulating factor (GM-CSF) as an adjunctive therapy for the treatment of acute myeloid leukemia (AML). METHODS: Randomized controlled trials (RCTs) of GM-CSF in the treatment of AML were retrieved from PubMed,EMBase,Cochrane Library,CBMdisc and CNKI database by computer as well as from the leukemia-related journals manually for a quality evaluation of the methodology and Meta analysis using RevMan5.0 software. RESULTS: A total of 10 RCTs were included,of which,3 RCTs were graded as A,5 as B and 2 as C. The results demonstrated that there were no significant differences of indexes among groups as complete remission (CR) rate,relapse rate,infection rate and length of hospital stay,etc. CONCLUSION: The available clinical research results showed that GM-CSF adjunctive therapy could neither increase CR rate,nor decrease the relapse rate,infection rate or length of hospital stay.

Runx2 is a transcription factor belongs to RUNXX family, and it is one of the important factors involved in expression and participation in regulation of mammary specific genes in the mammary gland. The overexpression is also as-sociated with certain characteristics of breast cancer. This article aims to summarize the recent progress of the role that Runx2 plays in breast cancer.

Objective Percheron artery is an uncommon anatomic variant. Percheron artery infarction with unilateral embryonic posterior cerebral artery ( PCA ) was rarely reported.The aim of this study was to characterize the clinical and imaging patterns of Percheron artery infarction with the unilateral embryonic PCA for early diagnosis and treatment.MethodsClinical and imaging data of 2 patients with Percheron artery infarction were reviewed retrospectively.ResultsTwo patients presented acute coma and one had paroxysmal blurred before coma.On neurological examinations,one patient had vertical gaze palsy besides two were unconsciousness. MRI showed symmetrical high signal intensity on diffusion weighed imaging (DWI)in bilateral paramedian thalami in two patients and a distinct pattern of V-shaped hyperintensity on DWI andFLAIR was present on the midbrain in one patient. Digital subtraction angiography and magnetic resonance angiography demonstrated unilateral embryonic PCA in two patients.ConclusionsThe classical clinical symptoms,symmetrical high signal in bilateral paramedian thalami and V-shaped sign in midbrain on DWI can improve recognition,evaluation and management of Percheron artery infarction.The unilateral embryonic PCA may be underlying risk factor of Percheron artery infarction.

Objective To evaluate the potential relationship between isoforms of BRCA1 associated RING domain 1 ( BARD1 ) and the pathophysiologic markers of sporadic breast carcinoma of female Han ethnic group. Methods The expression of BARD1 isoforms in 39 breast carcinomatous tissue, 12paracancerous-normal breast tissue and 7 controlled normal breast tissue was detected by reverse transcription polymerase chain reaction (RT-PCR) and then cloned and sequenced.The difference of isoforms expression and their clinical significance were analyzed. Results There were four transcriptive products of BARD1 found in all these candidates,named full lenth,isoform γ,isoform δ and isoform e.The positive rate of isoform γ and δ was higher in carcinomatous tissues than in paracancerous-normal tissues and normal breast tissue in healthy women ( P ＜ 0.05 ). Carcinomatous tissue expressed more kinds of isoforms.There was significant difference between carcinomatous tissue and paranormal/nomal tissue ( P =0.0075 ).There was significant correlation between isoform ε positive and poor prognosis factors such as poorly differentiation,HER2 positive,poor pathologic type and larger breast cancer lumps(P ＜ 0.05 ). Conclusions There are significant differences in the expression of BARD1 isoforms among different kinds breast tissues in the female Han ethnic group.Positive isoform ε may predict poor prognosis of breast carcinoma in the female Han ethnic group.

Objective: To study the relationship between human herpes vi rus 6 (HHV-6) infection and oral squamors cell carcinoma. Methods: The serum anti-HHV-6 antibody titers from 16 cases of oral squamors cell carcinoma (OSCC) and 16 control subjects were detected by indirect immunofluores cence assay. HHV-6 DNA in peripheral blood mononuclear cells was amplified by P CR and the specificity was confirmed by Southern-blot hybridization with an int ernal probe oligonuclotide. An immunohistochemical staining was used to detect H HV-6 antigen in OSCC tissues. Results: Positive expression of s erum HHV-6 IgG antibody was found in all the cases of OSCC and in 12 of the 16 controls. Geometric mean titer of OSCC group and control group was 1∶118 and 1 ∶64 respectively (P

A) in COL1A1 gene resulting in OI in a Chinese family. The detailed molecular and clinical features will be useful for extending the evidence for genetic and phenotypic heterogeneity in OI and exploring the phenotype-genotype correlations in OI.

A cross-sectional survey of 3589 adolescents was conducted in three cities from different typical geographical zones of Guangdong province. The median urinary iodine concentrations (MUI) of adolescents in Nanxiong, Guangzhou and Maoming were 286.6,204.1 and 166.0μ/L, respectively. The MUI of all these adolescents Was 231.7μg/L, which was slightly higher than the current World Health Organization recommendation.

Objective To explore the values of detecting anti-Saccharomyces cerevisiae antibody (ASCA) IgA,ASCA IgG,anti laminaribioside carbohydrate antibody (ALCA),anti-chitobioside carbohydrate antibody (ACCA) and anti mannobioside carbohydrate antibody (AMCA) and antibody against outer membrane porin C of Escherichia coli (anti-OmpC) in the diagnosis of Crohn's disease (CD).Methods From October 10th 2012 to January 24th 2013,63 patients diagnosed as CD were selected.At the same period 30 patients diagnosed as ulcerative colitis (UC) were set as disease control group and 25 individuals without abnormal findings under endoscope and imaging examination were set as healthy control group.Fasting blood of all the subjects were drawn in the morning and serum was isolated after centrifuge.The level of ASCA IgG,ALCA,AMCA,ACCA,ASCA IgA,anti OmpC and I2 was detected by indirect enzyme linked immunosorbent assay.The sensitivity,specificity,positive predictive value and negative predictive value of each antibody were calculated and its value in the diagnosis was evaluated by receiver operating characteristic (ROC) curve.Results In the differential diagnosis of CD and UC by single antibody test,the accuracy of AMCA was the highest and the area under ROC curve was 0.739.In the screening of CD with single antibody examination,the diagnosis accuracy of I2 antibody was the highest and the area under ROC curve was 0.751.In multi antibodies joint examination,the accuracy of either ASCA IgA or AMCA positive was the highest in the differential diagnosis of CD and UC,also in the screening of CD and the area under ROC curve was 0.612 and 0.633,respectively.Conclusion In clinical practice,CD screening and the differential diagnosis of CD and UC may be achieved through detecting AMCA,ASCA IgA and I2 antibody.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.
