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.

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 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.

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.

Background and purpose:Esophageal carcinoma is a common malignant tumor.Patients with esophageal carcinoma have a low survival rate.CD44 gene and CYP2E1 gene are related to invasion and metastasis of esophageal cancer,therefore we studied CD44 and CYP2E1 gene polymorphism in regard to its relationship with esophageal cancer. Methods :We analyzed CD44 and CYP2E1 genetic polymorphism in 45 cases with esophageal cancer and adjacent tissues by PCR technology. Results :CD44 protein was significantly over-expressed in tumor tissues than that in adjacent tissue(P

[Objective] To evaluate the efficacy and short-term results of selective expansive open-door laminoplasty(ELAP).[Method] From June 2005-June 2006,a total of 102 pataents with cervical spondylotic myelopathy(CSM)were enrolled in this study.Forty-four patients underwent ELAP.Fifty-eight patients undergoing conventional C3~7 ELAP served as controls.The clinical results and radiological examinations of both groups were evaluated at 12 month after surgery.[Result]There was no significant difference in recovery rate of Japanese Orthopaedic Association(JOA)scores.The incidence of axial symptoms in the selective ELAP group was significantly lower than those in the C3~7 ELAP group(P

Objective: To prepare a collagen rnembrane and to investigate its feasibi1ity as a derma1 scaffold. Metbods:Pig hide collagen was dispersed in 0. 5 mol/L acetic acid, co-precipitated with chordroitin-6-sulfate and lyophilized for 48 h toproduce a highly porous membrane. Cross-linking was in 0. 25% glutaraldehyde for 24 h. The membrane was implanted be-neath the flaps on the dorsal sites of SD rats. After implantation, biopsies were obtained periodically to study the tissue com-patibility, vascularity and stability. Results: The average pore size of the spongiform collagen membrane was 100 pm. Sub-dermal implantation of it showed that the inflammation was minimal, with no evidence of an acute rejective reaction. Conclu-siou: The spongiform collagen membrane prepared is easy to secure and produce, it has satisfied tissue compatibility, abilityof vascularity and optimum dermal scaffold structure.
