ObjectiveTo explore the effect of comprehensive rehabilitation therapy on wrist-hand functional disorder after fracture.Methods14 patients with wrist-hand functional disorder after fracture were treated with comprehensive rehabilitation therapy,including recovery of range of motion (ROM),functional exercise,occupational therapy,and physical therapy. The therapeutic effect was evaluated by ROM of wrist-hand joint (TAM) and activity of daily living (ADL).ResultsAfter treatment,patients' ROM and ADL were incrased than before (P<0.05).ConclusionComprehensive rehabilitation therapy has definitely therapeutic effect on wrist-hand functional disorder.

OBJECTIVETo screen the molecular markers for refractory anemia with excess blasts in transformation (RAEB) in myelodysplastic syndromes (MDS) by serum proteome profiling.

METHODSThe serum protein were isolated from patients with RAEB, acute myeloid leukemia or normal subjects by 2-dimensional electrophoresis (2-DE), and the electrophoresis gels were obtained to identify the differentially reacting protein spots. The replica gels of the differentially reacting proteins were analyzed to locate the matching protein spots, which were identified by peptide mass fingerprint based on matrix-assisted laser desorption/ionization time of-flight mass spectrometry (MALDI-TOF-MS) and database searching.

RESULTSSeven differentially expressed proteins in RAEB were found by 2-DE. Of the 7 proteins, 4 were identified by MALDI-TOF-MS to have significantly differential expression in RAEB, including dipeptidyl peptidase (DPP/CD26), polymerase (DNA directed) kappa, PRO2044 and an albumin-like protein.

CONCLUSION2-DE-based serum proteome profiling helps identify serum proteomic biomarkers related to MDS. DDP/CD26 has increased expression in the serum in RAEB subtype MDS, suggesting its possible role in advanced MDS.

Purpose: Triple-negative breast cancer (TNBC) is highly malignant and has poor prognosis and a high mortality rate. The lack of effective therapy has spurred our investigation of new targets for treating this malignant cancer. Here, we identified RON (macrophage-stimulating 1 receptor) and MET (MET proto-oncogene, receptor tyrosine kinase) as a prognostic biomarker and therapeutic targets for potential TNBC treatment. Materials and Methods: We analyzed RON and MET expression in 187 primary TNBC clinical samples with immunohistochemistry. We validated the targeted therapeutic effects of RON and MET in TNBC using three tyrosine kinase inhibitors (TKIs): BMS-777607, INCB28060, and tivantinib. The preclinical therapeutic efficacy of the TKIs was mainly estimated using a TNBC xenograft model. Results: Patients with TNBC had widespread, abnormal expression of RON and MET. There was RON overexpression, MET overexpression, and RON and MET co-overexpression in 63 (33.7%), 63 (33.7%), and 43 cases (23.0%), respectively, which had poor prognosis and short survival. In vivo, the TKI targeting RON ant MET inhibited the activation of the downstream signaling molecules, inhibited TNBC cell migration and proliferation, and increased TNBC cell apoptosis; in the xenograft model, they significantly inhibited tumor growth and shrank tumor volumes. The TKI targeting RON and Met, such as BMS-777607 and tivantinib, yielded stronger anti-tumor effects than INCB28060. Conclusion RON and MET co-overexpression can be significant pathological characteristics in TNBC for poor prognosis. TKIs targeting RON and MET have stronger drug development potential for treating TNBC.

OBJECTIVETo investigate the prevalence of peripheral arterial disease (PAD) in China type 2 diabetic patients and to demonstrate the relationships between putative risk factors and PAD.

METHODSIn total 1,397 type 2 diabetic patients aged 50 years and older were enrolled and determined ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) in 15 Class III Grade A hospitals in 7 major cities of China.

RESULTSMean patient age was 63.7 +/- 8.2 years and mean duration of diabetes mellitus was 9.39 +/- 7.4 years. Two hundreds and seventy-two (19.47%) patients were diagnosed as PAD by ABI < 0.9, 122 (18.37%) in male and 150 (20.46%) in female. PAD patients had a significantly longer duration of diabetes mellitus, higher hemoglobin A1c, and a significantly lower mean body mass index than non-PAD ones. Aging, smoking, and systolic blood pressure were found to be positively related with the prevalence of PAD. In terms of lipid profiles, no variable was found to relate with PAD. Notably, baPWV showed as the same significant guiding index for PAD, almost matched with ABI.

CONCLUSIONSPAD is a common complication in China type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for diabetic patients with high risk factors.

Carboxylesterase 1 (CE1) is an important serine hydrolase in mammals, which involved in the hydrolysis of a variety of compounds (endogenous substrates like cholesterol and xenobiotic compounds like ester-contain drugs and pesticides). This study aimed to design and develop the fluorescent probe substrates for human carboxylesterase 1 (hCE1), on the basis of the structural features of hCE1 preferred substrates. Four carboxylic esters deriving from BODIPY-8-carboxylic acid were designed and synthesized. After then, reaction phenotyping assays and chemical inhibition assays were used to evaluate the selectivity of these four ester derivatives towards hCE1. Our results clearly demonstrated that the substrate specificity of these ester substrates towards hCE1 would be improved with the decrease of the alcohol group on BODIPY-8-carboxylesters, while BODIPY-8-carboxylesters with small alcohol groups including methyl (BCM) and ethyl (BCE) esters could serve as the ideal probe substrates for hCE1. Given that BCM exhibit rapid hydrolytic rate in hCE1, we further investigate the enzymatic kinetics of this fluorescent probe substrate in both human liver microsomes (HLM) and recombinant hCE1, as well as to explore its potential application in high-throughput screening of hCE1 inhibitors by using HLM as enzyme source. The results showed that the kinetic behaviors and the affinity of BCM in HLM is much closed to those in recombinant hCE1, implying that hCE1 played the key roles in BCM hydrolysis in HLM. Furthermore, the inhibition study demonstrated that BCM could be used for rapid screening and characterization of hCE1 inhibitors, by using HLM to replace recombinant hCE1 as enzyme source.

OBJECTIVETo study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome (MetS) and risk factors in adults in China.

METHODSA cross-sectional survey was condcuted in 14 provinces (autonomous region, municipality) in China. A total of 47,325 adults aged⋝20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation (IDF) criteria and modified IDF criteria.

RESULTSThe age-standardized prevalence of MetS was 24.2% (22.1% in men and 25.8% in women) and 19.5% (22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1% (8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity (90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions.

CONCLUSIONUsing both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.
