Objective To study the effect of femoral offset reconstruction ON the Harris hip score and the hip ROM (range of motion) after artificial hip replacement in femoral neck fractures. Methods Follow-ups were conducted for 47 patients who had undergone artificial hip replacements for their unilateral femoral neck fractures. We took X-ray pictures to compare the femoral offsets at the affected and unaffected hips. The operated hips were evaluated by the Harris hip score. Statistical analyses were performed with SPSS l2.0 software. Results The Harris hip score of the operated hip was positively related to femoral offset reconstruction(t=7.25,P＜0.001).There was a significant and positive correlation between femoral offset and the hip abductor ROM(r=0.80,P＜0.001).The rate of femoral offset reconstruction had no significant difference between total hip arthroplasty and bipolar hip arthroplasty (χ2=0,P＞0.05).Conclusions Reconstruction of femoral offset after artificial hip replacement in the femoral neck fractures can improve funetional recovery and ROM of the hip. Femoral offset reconstruction is uncorrelated to the selection of total hip arthroplasty or bipolar hip arthroplasty.

Death-associated protein kinase (DAPK) is a muhidomain calcium/calmodulin (CaM)-de- pendent Ser/Thr protein kinase with an important role in apoptosis regulation and tumor suppression. DAPK may serve as a diagnostic and prognostic tool to evaluate disease severity, progression, metastatic rate, and re- currence, and may serve as a target for therapeutic intervention.

Objective:To compare the difference between the measurement methods of wire and divider applied in the measurement of arch length at orthodontic dental model analysis.Methods:80 pairs of dental models were selected,including 40 normal occlusion models and 40 crowded models.The arch length of every model was measured by the wire and divider methods respectively,and the casual error and paired t test was subsequently employed to compare the difference between the measurements data.Results:The variance coefficients of the dental lengths measured by the divider method was larger than those measured by the wire method in both crowding and normal occlusion(P

OBJECTIVE:To review the status quo and problems in the study of TCM formula granule.METHODS:Recent literature concerning the preparation technology and the normalization of quality criteria,etc.of TCM formula granule reported were reviewed and analyzed.RESULTS&CONCLUSION:TCM formula granule was of many merits such as safe and sani-tary,accurate in dosage measurement,portable etc.However,there are also some problems yet to be solved.

Neovascular age-related macular degeneration (AMD) is the main cause of vision loss in AMD patient.Now,the application of anti-vascular endothelial growth factor(VEGF) has become the preferred therapy for the treatment of neovascular AMD,and it has been proved to improve the visual acuity and reduce the blindness rate.But the formation of choroidal neovascularization (CNV) in AMD is a comprehensive and integrated pathological process.It is difficult to cure the CNV with only anti-VEGF drug for all the neovascular AMD patients.Therefore,the targeting drugs toward other signal pathway associated with CNV are being in different phases of clinical trials.Resent years,with the development of science and technology,small interference RNA(siRNA) and genome technology has been applied to treat neovascular AMD and show a potential prospect,and gene therapy and stem cell therapy are the most remarkable and predominant ways for AMD.Doubtlessly,these therapies offer novel choice for the management of neovascular AMD.

Case report form (CRF) is a key document for data collection in clinical trials. A well-designed CRF is required for database construction, data accuracy, data query/cleaning, CRF completion and statistical analysis. A well-defined process or SOP should be in place for CRF design. Data collection should fully meet the demand of study protocol. The layout of CRF should be clear with well-structured fields and standard coding for fields.

Objective To test the role of a bioartificial kidney which consisted of a continuous vein-vein hemofiltration (CVVH) system and renal proximal tubule cells (PTCs)device, also called the renal tubule assist device (RAD),in endotoxin shock.Methods Female crossbred pigs 25 to 30 kg received with 3×1011 bacteria / kg body weight of E.coli intraperitoneally followed by treatment with a sham RAD without cells (n=7) or a RAD with cells (n=7). Data on blood pressure, cardiac output, renal blood flow and systemic marker of inflammation (IL-6) were measured.Results Cardiac outputs and renal blood flows were higher in the RAD group with cells than in the sham RAD group after E.coli infusion (P＜0.05). Plasma IL-6 levels were lower in the cell RAD group than in the sham RAD group after bacterial administration (P＜0.05). A significant difference on survival time was also observed between the two groups,with(9.07 ± 0.88) h in the cell RAD group vs. (5.10 ± 0.46)h in the sham RAD group, P＜ 0.01.Conclusion The bioartificial kidney containing PTCs can improve cardiovascular function,reduce cytokine levels,and prolong survival time.
