1.Endometrial stromal stem cells from early-pregnancy decidua differentiate into endometrial epithelial cells
Chinese Journal of Tissue Engineering Research 2016;20(14):2098-2103
BACKGROUND:Decidua tissue is one of the most important sources of endometrial stem cel s, from which stromal stem cel s can differentiate into various kinds of cel s under contain inductions. OBJECTIVE:To observe the differentiation of endometrial stromal stem cel s isolated from early-pregnancy decidua into endometrial epithelial cel s. METHODS:Endometrial stromal stem cel s from early-pregnancy decidua were cultured, identified and directional y induced. Then induced cel s were randomized into test group cultured in conditioned medium and control group cultured in normal culture medium containing fetal bovine serum. Expression of keratin was detected by immunofluorescence assay and western bolt assay in the two groups. RESULTS AND CONCLUSION:The endometrial stromal stem cel s from early-pregnancy decidua were successful y isolated and cultured, and presented with a S-shaped curve. Within 1-48 hours after inoculation, cultured cel s were in the adaptation phase;then, the cel s proliferated rapidly and began to grow logarithmical y at 48 hours after culture;after 60 hours of culture, the cel growth rate decreased, with a steady rise in the cel curve. Results from the flow cytometry detection showed that the endometrial stromal stem cel s could express CD73 and CD90, but not express CD34, CD45 and cytokeratin. Immunofluorescence findings showed the expression of keratin negative in the control group, and mostly positive in the test group. Besides, the relative expression of keratin in the test group was significantly higher than that in the control group (P<0.05). These results suggest that the endometrial stromal stem cel s can be isolated from the human decidua in early pregnancy, and differentiate into endometrial epithelial cel s by directional induction.
2.Research advances on risk factors for arm lymphedema following breast cancer surgery
Journal of International Oncology 2010;37(10):755-758
Arm lymphedema is a common and persistent complication of breast cancer surgery. Surgery or radiotherapy damages axillary lymphatic vessels and obstructs lymphatic reflux, leading to the accumulation of lymph fluid in the superficial soft tissues of the upper limbs and the subsequent formation of edema. Clinical treatment of breast cancer-related lymphedema remains a worldwide problem. Currently, there is still no cure.

6.Variation of prothrombotic state markers in patients with type 2 diabetes mellitus who have microvascular complication
Chinese Journal of Postgraduates of Medicine 2015;(11):834-836
Objective To investigate the variation of coagulation parameters in type 2 diabetes mellitus(T2DM)patients with microvascular complication. Methods Coagulation and fibrinolysis parameters were measured in 40 healthy controls (control group) and 80 T2DM patients (T2DM group) with (47 patients) and without (33 patients) microvasular complications. Results Compared with those in control group, the serum levels of fibrinogenand D-D dimmersin in T2DM group were found to be increased significantly:(4.29±1.70) mg/L vs. (3.12±0.49) mg/L, 0.395 (0.265-0.910) mg/L vs. 0.215 (0.163-0.300) mg/L, P<0.05;while the activity of antithrombin III and protein S levels were significantly decreased in T2DM group:(94.11±25.04)%vs. (103.90±12.48)%,(70.23±23.22)%vs. (90.35±17.35)%, P<0.05. Amongst the T2DM patients, the serum levels of APTT, fibrinogen,D-D dimmers, and the activity of protein S in patients with microvascular complication were found to be significantly higher than those in patients without microvascular complication:(38.09±5.73) s vs. (34.53±4.13) s,(4.60±1.93) mg/L vs.(3.86±1.21) mg/L, 0.630(0.320-1.200) mg/L vs 0.310(0.240-0.405) mg/L, (79.4± 22.16)%vs. (57.15±18.05)%, P<0.05. Conclusion Hypercoagulable state and decreased anti-coagulation ability may contribute to the risk of development of microvascular complication in T2DM patients.

Journal of Practical Stomatology 2015;(1):44-47
Objective:To evaluate the clinical outcome of transcrestal maxillary sinus floor elevation(TMSFE)in the presence of pseudocyst.Methods:14 cases with pseudocyst were treated by TMSFE.In the operation following osteotome,pseudocyst was not ex-cised and sinus floor membrane was elevated,15 implants were placed for the 14 cases.Definite prosthesis was delivered about 6 months after implant placement.CBCT examination was done before,immediately after and 1-year after surgery,the cyst condition, the gain of vertical bone height and implant stability over time were observed.Results:Pre-operation residual ridge height of the alveo-lar crest was (6.85 ±1.07)mm.The sinus membrane was successfully elevated in all sites without perforation (mean elevation height,6.93 ±2.07)mm.All 15 implants were ossteointegrated.At 1-year revisit the gained bone height was (12.76 ±2.03)mm. Cyst grew bigger in 3 cases,not changed in 3 cases,became smaller in 5 cases and disappeared in 3 cases.Conclusion:Pseudocyst excision is not necessary in TMSFE.
9.Biological characteristics and molecular biology research hotspots of extranodal NK/T-cell lymphoma,nasal type
Journal of Leukemia & Lymphoma 2012;21(1):19-25
Extranodal NK/T-Cell lymphoma,nasal Type (NKTL) is an individual type in the World Health Organization (WHO) classification.The reports for NKTL are relatively uncommon since the incidence of this disease is low. In recent years, the nude mice model and cell lines of NKTL were established which built up the basis of researches in molecular biology. The investigation are carried out in molecular genetic analysis of lymphoproliferative disorders,tumor microenvironment,and target therapy and so on.We reviewed those advances and concentrated on the development of NKTL molecular biology.
10.Introduction to hip-stress lower-limb specific strength training apparatus
Chinese Journal of Tissue Engineering Research 2008;12(22):4397-4400
Hip-stressed lower limb specific strength training apparatus is a new kind of training equipment with the combination of specific technical strength training and quantitative evaluating. Base on the mechanism of sports physiology and sports biomechanics, by applying the theory of motor learning and control, the apparatus adopts the training model of the "hip stress loading device" and "hip-feet starting and ending stress point" to simulate the track of working limb in running, jumping and throwing, controls the degrees of body movement freedom reasonably. For the first time, actualizes the heavy load specific strength and sports skill training of leg driving, leg pawing and trunk-backward knees-bend leg driving. The distinctive training pattern of forced track control and the training method of strength & skill coupling" used in this apparatus, makes the action in strength training approach to real sport skill in greatest extent, and shifts the result of strength training to the skill training as much as possible. So it remarkably increase the efficiency of strength training and has an great importance in changing the concept of strength training.
