Objective To explore efficacy and mechanism of recombinant human granulocyte-colony stimulating factor(rhG-CSF)in treatment of different leukopenia.Methods A total of 50 patients were divided into 4 groups:aplastic anemia(AA)group(n=10),myelodysplastic syndromes(MDS)group(n=10),drug-induced leukopenia group(n=20)(subdivided into hyperplasia group and hypoplasia group by the degree of cellularity)and iron deficiency anemia group(control group,n=10).The concentrations of G-CSF of peripheral blood were measured by ELISA method.The ratio of CD34+ cells and G-CSFR expression in blood marrow mononuclear cells(BMMNC)were measured by flow cytometry.Granulocyte colony-forming units(CFU-G)of MNC were cultured.Clinical efficacy of rhG-CSF to all patients were determined.Results The concentrations of G-CSF were higher in AA and drug-induced leukopenia groups than those of MDS and control groups(P0.05).Expressions of G-CSFR were lower in hypoplasia group than those in hyperplasia and control groups(P0.05).The ratio of CD34+ cells was lower in AA group than that of other groups(P0.05).Concentrations of CFU-G were lower in AA and MDS groups than those in drug-induced leukopenia and control groups(P0.05).The efficacy of rhG-CSF was superior in drug-induced leukopenia group than in MDS group,and superior in MDS group than in AA group(P

Objective To explore the clinical effect of arthrolysis and a hinged external fixator for treatment of posttraumatic elbow stiffness.Methods From April 2007 to April 2012,26 cases of posttraumatic elbow stiffness patients were treated with arthr o lysis and a hinged external fixator after operation,and the effect was observed.Results After operation,26 patients were followed up for 15(8-24) months,the ranges of elbow joint motion increased from (42 ± 17) ° to (119 ± 17) ° after operation.There was significant difference (t =152.85,P＜ 0.05).The MEPS scores increased from (36 ± 13) points to (82 ± 14) points after operation,15 cases were excellent,5 cases were good,3 cases were fair and 3 cases were poor,the rate of excellent and good cases was 76.9％ (20/26).Twenty-three cases (88.5％,23/26)elbow function improved.Postoperative infective complication occurred in 1 case,postponed incision healing occurred in 1 case and 1 patient had cubital nerve paralysis,the symptom disappeared after 3 months and the patient showed no instability in elbow joint.Conclusion Arthrolysis and a hinged external fixator can deep stabe the elbow and its specific position,allowing early rehabilitation to promote functional recover of the elbow.

Objective To explore the effects of ginsenoside Rg3 on the expression of P27 in human erythrol-eukemia cell line K562 and cell proliferation. Methods Human erythroleukemia cell line K562 cells were cultured to exponential phase, then K562 cells were treated with different concentrations of Rg3 (6.25, 12.5, 25, 50, and 100 μg/mL) as Rg3 group, and cells treated without Rg3 (0 μg/mL) were take as control group. After 3 days, K562 cells were observed by Wright-Giemsa staining with microscopy , the proliferation of K562 cells were examined by tetrazolium salt (MTT) assay, and the expression of P27 mRNA were detected by fluorescent quantitative RT-PCR assay. Results MTT assay showed that after treatment with Rg3,the inhibition rate (IR) of proliferation of cells in Rg3 groups were increased gradually , and the differences were significant compared with the control group (P < 0.05). The results of fluorescent quantitative RT-PCR showed the levels of P27 mRNA expression in 25,50 and 100 μg/mL Rg3 groups were significant higher than that of control group (P < 0.05). Conclusion The ginsenoside Rg3 can inhibit the proliferation of K562 cells by inducing the expression of P27.

OBJECTIVETo explore clinical characteristics and treatment of posterior Pilon fracture.

METHODSFrom January 2011 to January 2013,18 patients with posterior Pilon fracures were treated. Among them, 13 were male and 5 were female, aged from 22 to 63 years old, with an average age of 46. All the patients were closed fractures. Open reduction and internal fixation were performed after swelling subsided, lateral malleolous and posterior Pilon fracture were exposured through lateral approach on healthy side, plates were used to fixed,screws or small plates were used to fix the posterior prominence of medial malleolus after changed to supine position. AOFAS scoring were applied to evaulate clinical effects.

RESULTSAll patients were followed up with an average of 22(ranged, 12 to 48)months. All patients obtained satisfactory reset except one patient. All factures were recovered well with an average healing of 11 weeks. According to AOFAS score at the final following up, 7 cases were excellent,2 cases were moderate, and the total score was 86.8±9.2.

CONCLUSIONPosterior Pilon fracture is not rare in clinical, its mechanism of injury, traumatic anatomy, surgical procedure and prognosis are different from that of classical ankle fracture and Pilon fracture.
