Twenty-five patients with traumatic carpitis treated by wrist fusion plate internal fixation in Department of Orthopedics, Commercial Staff Hospital of Wuhan from July 2000 to July 2007 were selected, of which 21 were followed up for more than 6 months. Twelve cases had slight dorsal extension dysfunction of thumb, forefinger and middle finger; 10 had slight initiative dorsal extension dysfunction of thumb interphalangeal articulation; 4 had forearm rotation dysfunction, such as distal radioulnar joint or ulnaris pain. Of 21 followed-up patients, 12 cases had no pain, 5 had bearable wrist pain after intensive physical labor, and 4 had pain in daily life of forearm rotation, which affected their working. Grip strength of 15 cases restored to 75% of the operate side, 5 cases to 50%-75%, and 1 case to 50%. The results suggest that plate implantation relieve joint pain, but partial wrist function is limited. The plate materials are biocompatible to human body with no specific adverse effects.

Aim: To explore the relationship between structure and immunological activity of marine polysaccha-ride YCP,the physicochemical property and immunological activity of the YCP-derived fragment were studied.Methods: YCP was hydrolyzed by α-amylase from human saliva.The hydrolysate was purified to obtain an polysaccharide fragment by gel filtration chromatography.The physicochemical properties of this YCP-derived fragment was characterized by HPLC,FT-IR and TLC.In addition,changes of phagocytic activity,production of reactive nitrogen and macrophage binding were investigated.Results: The relative molecular weight of YCP-de-rived fragment was approximately 6.6 × 10~3.The monosaccharide composition and FT-IR of the YCP-derived frag-ment were identical to YCP.No significant effect of the YCP-derived fragment on NO production and murine mac-rophage phagocyte were observed.And this fragment was not able to compete the binding between YCP and mac-rophages.Conclusion: The remarkable decrease of immunological activity of YCP-derived fragments degraded byα-amylase of human saliva suggests that the complete structure and high molecule weight of YCP are essential for its immuno-modulatory activity.

Objective To further define the molecular mechanism involved in the metastasis process in lung cancer and screen out the genes expressed differentially in the lung cancer.Methods mRNA differential display (DD-PCR) was employed to search the specific genes related to metastasis.The highly expressed fragments were cloned and sequenced.Compared with the data in GenBank,the homologous genes were found.The anchor primers were designed to validate the candidates from DD-PCR by real-time PCR.The structure of the gene was prognosticated by software.Results Nine differentially expressed genes were found.One of the nine genes,which named C3orf1,showed high different expression within the six tested cancer cells.The gene was 858bp long and encoded 285 amino acids.The molecular weight was about 32.2 kD.Analyzed by the bio-software,it was found that the gene was consisted with seven EGF-like domains (EGF_1),three 2Fe-2S ferredoxin/iron-sulfur binding regions (2FE2S_FER_1),two VWFC domains (VWFC_1),two thiolase active sites (thiolase_3),and so on.Conclusions The gene C3orf1 is over-expressed in the lung cancer 95D cells.It may encode a familiar secretary growth factor protein and play important role in stimulating growth of the cells.

In this study,a series of related indicators were investigated via flow cytometry,enzyme-linked immu-no sorbent assay (ELISA)and quantitative real time PCR (Q-PCR)technology to assess the in vitro differentia-tion of human Th17 cells.Human peripheral blood mononuclear cells (PBMCs)were purified from fresh human blood using gradient centrifugation and then the Th17 cells were induced with different cytokines (IL-1β,IL-6, TGF-βand IL-23)at different induction time (1,2,3,4 d)to compare the effects on Th17 cell differentiation un-der these conditions.The experiment data showed that IL-1β,IL-6,TGF-βor IL-23 alone play a promotion role in the Th17 differentiation and combination of IL-1β,IL-6,TGF-βand IL-23 could induce efficient human Th17 cell differentiation in vitro to achieve the best.Further optimization of the induction time found that the Th17 cell dif-ferentiation efficiency gradually increased with the extension of the time;howerver,when culturing for 3 d,it reached the peak number and then decreased in regardless of the time increasion.Finally the optimal condition of in vitro polarization of human Th17 cells was established,and the purified PBMCs were cultured with anti-CD3 and anti-CD28 as the basal conditions,and co-culturing with IL-1β,IL-6,TGF-βand IL-23 for 3 d to effectively induce the differentiation of Th17 cells.The inducing efficiency is significantly higher than in normal control.At the optimal condition,we observed the Th17 cell differentiation frequency (CD4 +IL17A +)was increased to nearly 10% through flow cytometry analysis and the secretion level of IL-17A in cell supernatants was also detec-ted to reach 3 ng/mL using ELISA methods.In addition,gene expression of IL-17A were determined by quantitativereal-time PCR using pre-designed primers by the comparative method of relative quantitation (ΔΔCt)and β-actin gene was used as an internal control for sample normalization.The results showed that the expression of IL-17A mRNA could be increased about 15 times with IL-1β,IL-6,TGF-βand IL-23 co-culturing for 3 d.The protocolof efficient human Th17 cell differentiation we presented in this paper is simple,rapid and easy to be repeated.This study provides an effective detection platform for the research of Th17 cell function and development ofrelated drugs targeting Th17 cells for autoimmune disease treatment.

Objective To investigate the correlation between serum adiponectin level and severity of coronary artery lesion. Methods The serum concentrations of adiponectin in 112 patients whom had received coronary arteriongraphy (CAG) were measured. Among them,58 cases had acute coronary artery syndromes(ACS)(ACS group), 25 cases had stable angina cordis(stable angina cordis group) and 29 cases had non-coronary disease (control group ). The severity of coronary artery lesion was evaluated by the number of stenosis vessel and Gensini score. All the patients were divided into single vessel lesion group (24 cases),double-vessel lesion group (26 cases ), triple-vessel lesion group (33 cases) by extent of disease; and 0- 1 score group (29 cases),2-20 scores group (28 cases),21-40 scores group (30 cases), ＞40 scores group (25 cases) by Gensini score. Results The serum concentrations of adiponectin in ACS group were lower than those in control group and stable angina cordis group[(6.43 ± 4.22 ) mg/L vs. ( 12.68 ± 6.47 ), (9.94 ± 8.48 ) mg/L]( P ＜ 0.01 or ＜ 0.05 ). The serum concentrations of adiponectin in control group were higher than those in single vessel lesion group, double-vessel lesion group and triple-vessel lesion group[( 12.68 ± 6.47 ) mg/L vs. (8.80 ±6.23), (8.04 ±5.93), (6.43 ±5.12) mg/L](P ＜0.01). The serum concentrations of adiponectin in single vessel lesion group were higher than those in triple-vessel lesion group (P＜ 0.01 ). The serum concentrations of adiponectin in 0-1 score group[.( 12.68 ±6.47) mg/L]and 2-20 scores group [(8.74 ± 6.68) mg/L]were respectively higher than those in 21-40 scores group[(7.64 ± 5.32) mg/L]and ＞ 40 scores group[(6.32 ± 5.46 ) mg/L](P ＜ 0.01 ). The serum concentrations of adiponectin in 21-40 scores group were higher than those in ＞ 40 scores group(P＜ 0.05 ). The serum concentrations of adiponectin were negatively correlated with the log of Gensini score (r = -0.584,P ＜ 0.01 ). Conclusion The decrease in serum adiponectin might reflect the increase in severity of coronary artery lesion.

Objective To evaluate the efficacy of itraconazole oral solution for prevention of invasive fungal infection ( IFI ) in neutropenic patients with acute leukemia after chemotherapy.Methods Clinical data of 136 neutropenic patients with acute leukemia after chemotherapy at the Department of Hematology,Nanfang Hospital from January 2008 to December 2010 were retrospectively analyzed.Patients were divided into itraconazole group ( n =67 ) and control group ( n =69).There were 36 patients with acute nonlymphocytic leukemia ( ANLL),31 with acute lymphoblastic leukemia (ALL) in itraconazole group;while in control group,there were 30 patients with ANLL,38 with ALL and 1 with biphenotypic acute leukaemia (BAL).Patients in itraconazole group received intraconazole after chemotherapy until the neutrophil count was increased to 0.5 × 109/L or the body temperature returned to normal and without any imaging evidence of IFI.The incidence of IFI and clinical features were compared between the groups using SPSS 13.0 software.Pearson x2 test was used for nominal variables,for measurement data,t (normal distribution) or Mann-Whitney U (skewed distribution) test were used.Results There were 12 cases ( 17.9％ ) suffering from IFI in itraconazole group and 32 cases (46.4％) in the control group (x2 =12.59,P ＜ 0.01 ).For ANLL patients,the incidence of IFI in itraconazole group was significantly lower than that in control group ( 16.7％ vs.56.7％,x2 =11.53,P ＜0.01 ).In itraconazole group,the incidence of IFI in female patients was significantly lower than that in male patients ( 8.6％ vs.28.1％,x2 =4.35,P ＜0.05 ).And for the female patients,the incidence of IFI in itraconazole group was significantly lower than thatin the control group (8.6％ vs.44.7％,x2 =11.98,P＜0.01).Conclusion Itranconzole oral solution can effectively prevent IFI in neutropenic patients with acute leukemia after chemotherapy,especially for the female patients with ANLL.

Objective: To investigate the relationship between miRNA-196b-5p and miRNA-99a-5p expression and autophagy and apoptosis in multiple myeloma cells. Methods: Human myeloma cell line U266 and normal CD138+ plasma cells were selected as the research objects. The subjects were divided into 45 cases of multiple myeloma patients and 40 healthy controls. The expression of miRNA-196b-5p and miRNA-99a-5p was measured by real-time quantitative PCR, and Western blot was used to determine the expression of autophagy related protein LC3-Ⅱ, LC3-Ⅰ, P62, Beclin-1 expression, apoptosis related protein CL caspase3, CL caspase7, Bcl-2, Bax, and TGF-β/Smad pathway associated proteins TGF-β1, Smad2/3, p-Smad3 and Smad7. The cell apoptosis rate was determined by flow cytometry. The correlation between miRNA expression level and clinical characteristics of multiple myeloma patients was analyzed. Results: Compared with normal plasma cells, the expression of miRNA-196b-5p in myeloma cells increased significantly (0.43±0.15 vs 2.44±0.63 or 2.02±0.85, all P<0.001), the expression of miRNA-99a-5p was significantly decreased (1.87±0.61 vs 0.62±0.15 or 0.80±0.33, P<0.001), LC3-Ⅱ/LC3-Ⅰ increased significantly (P<0.05), Beclin-1 expression increased significantly (P<0.05), P62 expression decreased significantly (P<0.05). The expression of Bax, CL caspase3 and CL caspase7 decreased significantly (P<0.05), and the expression of Bcl-2 increased significantly (P<0.05) and apoptosis rate significantly decreased (P<0.05). After transfected with miRNA-196b-5p mimic or miRNA-99a-5p inhibitor, the LC3-Ⅱ/LC3-Ⅰ of CD138+ plasma cells increased significantly (P<0.05), the expression of Beclin-1 increased significantly (P<0.05), P62 expression decreased significantly (P<0.05), and the apoptosis rate significantly decreased (P<0.05). However, after autophagy inhibitor of 3-MA was administered, the apoptotic rate of the above reaction system did not change significantly (P>0.05). The expression of miRNA-196b-5p and miRNA-99a-5p was significantly correlated with DS and ISS stage in multiple myeloma patients (P<0.05). Conclusion miRNA-196b-5p and miRNA-99a-5p are closely related to the clinical characteristics of patients with multiple myeloma. The overexpression of miRNA-196b-5p and down regulation of miRNA-99a-5p could inhibit the apoptosis of myeloma cells by up regulation of autophagy, and the mechanism is related to the activation of the TGF-β/Smad signaling pathway.
