To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective:To observe the effects of orbital bone density on the stress distribution of implant-bone surface.Methods:The 3D finite element analysis craniofacial model with eight HU values(300 -1 0 000)was established.A force of 20 N along the im-plant axis was applied on the model.The stress values and distribution were calculated and analyzed.Results:The peak of stress val-ue and displacement discreased as HU value increased.In the range of HU value 800 -1 000 HU,the peak of stress value and dis-placement of bone interface did not significantly change with the increasing of HU value.Conclusion:Orbital bone density is an im-portant factor on orbital implant failure when HU value below 800.

Objective:To study the clinico-pathologic characteristics, molecular phenotypes, and prognosis of young breast can-cer patients. Methods:Data from 133 low-age (age≤30 years) young breast cancer patients and 117 young (31 years≤age≤35 years) breast cancer patients who underwent surgery between January 2002 and December 2009 were reviewed. Cases of the middle and old-age elderly (age>35 years) breast cancer patients during the corresponding period were randomly selected as matched controls. The clinico-pathologic characteristics, molecular phenotypes, and prognosis were retrospectively analyzed. Results:The low-age young and young breast cancer patients significantly differed from the elderly patients in terms of tumor size, lymph node metastasis, histological grading, molecular phenotype, and relapse (P<0.05). The low-age young patients are more vulnerable to have triple-negative breast can-cer, recurrence, and distant metastasis (P<0.001). Moreover, the low-age young patients have lower overall survival and disease-free survival than the other groups (P<0.05). Conclusion:Young breast cancer patients have poor prognosis compared with the elderly. Ear-ly screening and prompt treatment are necessary for young breast cancer patients.

Objective To open out new method,we probe into immune function of??ST and NKT cells in NSCLC.Methods The peripheral blood cells were stained with antibodies labeled with fluorescence in NSCLC,??T,NKT and their set group cells were counted with flow cytometry.Results The absolute counts of??T,CD~+_(56)??T,CD~-_(56)??T,NKT and??T~+ NKT cells in NSCLC was significantly lower than that of normal controls.The relative counts of NKT,??T~+ NKT,??T~-NKT and CD~+_56??T cells in NSCLC was not sig- nificantly lower than that of normal control.The absolute counts of??T cells in NSCLC positively correlated to the number of NKT cells,(r=0.426,P=0.009).Conclusion The absolute counts of??T,NKT and their set ground cells in NSCLC was significantly lower than that of normal controls.In NSCLC the relation of the??T and NKT had positive correlation.

To ascertain the optimal harvest period of Lonicera Flos (Lonicera macranthoides) the configuration yield and quality of L. macranthiodes bloom verity and bud verity flower at different develop periods were Observed. The quality of L. macranthiodes which harvested at different times of the day was Compared. The configuration was significant difference between different develop period of L. macranthiodes flower. As bud growth, yield increased. Bloom verity of L. macranthoides chlorogenic acid content was significantly lower after opening (silver flower stage, golden flower stage), before opening (young bud stage, green-white stage) have no significant difference of the quality. Bud verity of L. macranthoides macranthoidin B is significant lower at yellow-white stage, young bud stage and green-white stage have no significant difference of the quality. The chlorogenic acid and isochlorogenic acid A content is significant difference between L. macranthoides harvested at different time of the day. The optimal harvest period of bloom verity is the white stage, picking time for 10:00 before and after 18:00. The optimal harvest period is the green-white stage, picking time is 8:00 before and after 18:00.

Objective To explore the damage effect of high level of glucose on ECV304 cells and the approaches in which high level of glucose plays its part to provide theoretical bases for the therapy of diabetes.Methods ECV304 cells were divided into four groups:normal control,high glucose group in which glucose was added to the cells with final concentration of 35 mmol?L-1,Radix Astragali(RA) group in which glucose was added to the cells with final concentration of 35 mmol?L-1,as well as RA with final concentration of 500 mg?L-1,mannitol group in which mannitol was added to the cells with final concentration of 25 mmol?L-1.The cells were cultivated for 24 h after the glucose,RA and mannitol were added to the cells and collected for the determination of intracellular Ca2+ concentration,mitochondrial membrane potential and the morphological changes of cells and mitochondria were observed under electronic microscope.Results The intracellular Ca2+ concentration in the cells of high glucose group was significantly higher than those of RA group,mannitol group and normal control group(P

Purpose The aim of this study was to reveal the role of SGT,the small glutamine-rich tetratricopeptide repeat (TPR)-containing protein,in the developing mouse brain through examining the expression profile of SGT during the development stage. Methods In this study, quantitative RT-RCR and Western blot were applied to investigate the expression of SGT mRNA and protein in the mouse whole brain. Western bolt was also used to detect the expression of SGT in the hippocampus, cerebral cortex, striatum and cerebellum. Immunohistochemical analysis on postnatal and adult mouse brain was performed to examine the subcellular localization of SGT. Results Our data showed that the levels of SGT mRNA and protein in the mouse whole brain were both high during the postnatal stage and declined in the adult. Regional expression of SGT protein in the hippocampus, cerebral cortex, striatum and cerebellum showed a similar expression profile.Immunohistochemical analysis found that in the P14 mouse brain, SGT was abundant in all the CA regions of hippocampus as well as most regions of cerebral cortex and striatum. In the cerebellum, SGT was mainly distributed in Purkinje cells. In the sections of the adult mouse brain, faint expression was observed in the regions mentioned above. Conclusions Our findings firstly exhibit the expression pattern of SGT in the mouse brain development,which might shed new light on further functional analysis of SGT in the central nervous system.

BACKGROUND:Bone nonunion is a common complication in the orthopedic treatment, and its morbidity reached 5%-10%, which results in the long-term functional disturbance of the limbs, and even disability. Autogenous iliac crest graft has been commonly used to treat bone nonunion, but some limitations stil exist.
OBJECTIVE:To investigate the treatment outcomes of autogenous iliac crest graft combined with autologous bone marrow stem cel transplantation for bone nonunion after fracture surgery.
METHODS:Clinical and fol ow-up data from 69 patients with bone nonunion were analyzed retrospectively. Al patients were al otted to combination (n=37) and iliac (n=32) groups, fol owed by treated with autologous iliac crest graft combined with autologous bone marrow stem cel transplantation or autologous crest graft, respectively. Afterwards, the hospitalization time, fracture healing time, bone mineral density and Fereadez-Esteve cal us scores were detected and compared between groups.
RESULTS AND CONCLUSION:The hospitalization time did not differ significantly between groups (P>0.05). The fracture healing time in the combination group was significantly shortened compared with the iliac group (P<0.05). The bone mineral density and Fereadez-Esteve callus scores in the combination group were significantly higher than those in the iliac group at 3 and 6 months after surgery (P<0.05). The excellent and good rate of the affected limb function in the combination group was significantly higher than that in the iliac group (P<0.05). These results suggest that autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion can accelerate fracture healing, promote porosis and improve the functional recovery of affected limbs.
