Objective To report the functional reconstruction and rehabilitation for a patient who under- went allograft for both of his forearms and hands.Methods One male patient underwent allograft for both of his forearms and hands in October 2002 in our department to reconstruct his hand functions.The allografted hands were intervened with an integrated rehabilitation program,which involved administration of immunosuppressants,post- operative monitoring,postoperative functional training,massage,physiotherapy,orthosis,performance training, sensation training,secondary operation and mental rehabilitation.The patient was followed up for 4 years.Results The forearms and hands of the patient were in good shape and regained nearly normal sensation.The distance of two-point-discrimination was 2.5 cm to 4.0cm.The TAM (total active motion) of fingers was fine.The patient could look after himself well and were healthy in psychology.Conclusion An integrated rehabilitation program can yield satisfactory results in the management of allografted forearms and hands.

Sulfate-reducing bacteria (SRB) are widespread in the environment. SRB are obligate anaerobes and capable of dissimilatory reduction of sulfate. SRB have application prospects in the control of environmental pollution due to that many pollutants can be removed by SRB. The biological characteristics and metabolic mechanisms of SRB are introduced, and the application of SRB in the treatment of environmental pollution is described in this paper. The research progress of Cr(Ⅵ ) reduction and Cr(Ⅵ ) removal from wastewater by SRB is reviewed, and future direction of research on the control of Cr(Ⅵ ) pollution by SRB is also analysed.

OBJECTIVETo study the therapeutic effects of posterolateral depression fractures of the tibial plateau through a modified anterolateral approach.

METHODSFrom February 2011 to January 2012,13 patients with posterolateral depression fractures of the tibial plateau were treated through a modified anterolateral approach. There were 8 males and 5 females, ranging in age from 28 to 59 years old (49.2 years old on average). Data from patients were collected retrospectively as follows: X-ray, time of fracture healing and the complications of fracture healing. The patients were evaluated both clinically and radiologically according to the Rasmussen score system.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months (mean 13.7 months). All the patients got bony union. The average radiographic bony union time was 15.1 weeks (ranged, 11 to 17 weeks). No case of secondary articular depression was found. No complications such as malunion or joint stiffness were found. But 1 patient had superficial infection and 1 patient had common peroneal nerve injury. According to the Rasmussen score system,the mean radiological score was 16.50 ± 0.67 (ranged, 13 to 18), and the mean functional score was 25.20 ± 2.21 (ranged, 13 to 30). The mean range of knee motion was (125.3 ± 9.3)° (ranged, 0° to 135°).

CONCLUSIONTreatment of depression fractures of posterolateral tibial plateau with a modified anterolateral approach is a safe method with effective exposure, due to its stable fixation and relatively good outcome with minimal soft-tissue complications. It is regarded as an ideal procedure for depression fractures of posterolateral tibial plateau.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.

METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.

RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.

CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

OBJECTIVE To investigate the beneficial effect of berberine (BBR) on atherosclerosis in Apo-/-E mice and explore the underlying mechanisms based on attenuating vascular inflammation and modulating calcification in human umbilical vein endothelial cells (HUVECs) and smooth muscle cells(SMCs). METHODS 48 Apo-/-E mice,at 6-8 weeks old,were randomly allocated into 4 groups:normal, model, bbr and atorvastatin (positive control) groups with 12 mice in each group. They were fed with high-fat diet for 4 weeks except those in Normal group and then treated with indicated drugs or solvent for another 4 weeks. The morphology and inflammation infiltration of aortic were examined with HE staining. The expression of BMP- 2 in aortic was examined by immumohistochemical staining. Blood lipid levels were examined by automatic biochemical analyzer. The expression of IL-6, TNF-αand BMP-2 in serum and tissues was detected by ELISA method. The expression of ALP and the content of calcium were detected by commercially-available kits. HUVEC cells were stimulated with TNF-α and incubated with various concentrations of BBR for 24 h. The contents of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule (VCAM-1), matrix metalloprotein-9 (MMP-9) in the culture supernatant were detected by ELISA method. Calcification was induced with β-glycerophos?phate in SMC cells and the effect of BBR on the content of calcium was examined. RESULTS 4-week berberine treatment markedly lowered serum TC and LDL-c levels and improved the plaquestabilityin Apo-/- E mice fed with a high- fat diet (P<0.05 or P<0.01) which was comparable with the effect of atorvastatin. Berberine also significantly decreased the levels of IL-6 and TNF-α in mice serum and aortic tissues (P<0.05 or P<0.001). Berberine tended to decrease ALP, BMP-2 levels and the content of calcium in mice serum and aortic tissues (P<0.05, P<0.01 or P<0.001) which were not observed in atorvastatin group. Berberine significantly lowered the levels of ICAM-1, VCAM-1, and MMP-9 in TNF-α-stimulated HUVECs. It can also lowered the content of calcium in SMCs. CONCLUSION BBR can profitably regulate the levels of blood lipid in mice fed with a high-fat diet, decrease the injury caused by inflammation, and attenuate vascular calcification. It may improve atherosclerosis and play a role in cardiovascular protection.

Objective To assess the impact of a single hemodialysis on the left ventricular systolic function of uremia patients with 3-dimensional ultrasound speckle tracking imaging (3D-STI).Methods Thirty-seven clinically stable outpatients with uremia undergoing hemodialysis were studied.The echocardiographic examinations were obtained in 30 minutes before and after homodialysis.Twenty nine normal subjects with age and sex matched were selected as control groups.Conventional ultrasound was recorded and then left ventricular mass index(LVMI) was calculated.The peak systolic mitral annular velocity S' was recorded by tissue Doppler imaging.3D-STI imaging were recorded from standard left ventricular apical 4-chamber views before and after a single hemodialysis.Left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV),left ventricular ejection fraction (LVEF),and left ventricular global longitudinal peak systolic strain (LVGLS),left ventricular global radial peak systolic strain (LVGRS),left ventricular global circumferential peak systolic strain (LVGCS),left ventricular global area peak systolic strain (LVGAS) were measured.The indicators of conventional ultrasound and 3D-STI were compared between the pre-hemodialysis group and the normal control group,and also between pre-and post-hemodialysis groups.Results ①Compared with the control group,the left ventricular end-diastolic diameter (LVDD),interventrieular septal thickness at diastole (IVSD),left ventricular posterior wall thickness at diastole(LVWPD),left atrial diameter(LAD) in the group before a single hemodialysis were significantly higher (P ＜0.05 for all).Meanwhile,the S' was significantly lower (P ＞0.05) and LVMI was significantly higher in the pre-hemodialysis group than the control group(P ＜ 0.05).The LVDD,LAD,left atrial volume index(LAVI) were significantly lower in the post-hemodialysis group than that in the pre-hemodialysis group(P ＜0.05 for all).②Results of 3D-STI showed that the LVEF,LVGLS,LVGCS,LVGRS,LVGAS was significantly lower,however LVEDV,LVESV were higher in the pre-hemodialysis group compared with the control group (P ＜ 0.05 for all).After a single hemodialysis,LVEDV,LVESV,LVGLS were significantly lower than before(P ＜0.05 for all),but LVEF,LVGRS,LVGCS,LVGAS were not significantly changed (P ＞ 0.05 for all).Conclusions After a single hemodialysis,the whole systolic function of the left ventricular was not changed.but the left ventricular global longitudinal peak systolic strain was significantly lower.The parameter of LVGLS was sensitive to the change of preload and was volume-load dependent.The preload of the patients should be sufficiently considered when the LVGLS are measured in the patients with uremia undergoing hemodialysis.
