Objective: In order to reveal the mechanisms of rh-endostatin and its suppression effect on HUVECs at different activating levels. Methods: Three types of HUVEC were prepared. We detected the ex-pression of CD105 and CD62E on the surface of adhering HUVEC, HUVEC of exponential phase of growth, and HUVEC activated with TNF-alpha. The effect of endostatin on these three types of HUVEC was indicated by the variation in the expression of CD105 and CD62E on the cells. The relationship of the changes in cell markers with the time and the concentration of endostatin was analyzed by SPSS 11.5. Results: The expres-sion of CD105 was correlated with time and dose of endostar in all groups. The expression of CD62E was cor-related with the dose of endostar in HUVEC treated with TNF-α for 24h. Conclusion: Endostatin of a certain dose can inhibit the activation of endothelial cells but it cannot induce cell apoptosis.
2.Clinical observation on combination therapy of Ninggan-Tiaozhong decoction and psychological intervention for 40 cases of chronic atrophic gastritis
International Journal of Traditional Chinese Medicine 2013;(5):435-437
Objective To survey the clinical effect of combination therapy of Ninggan-Tiaozhong decoction and psychological intervention for chronic atrophic gastritis (CAG).Methods 80 cases CAG were randomly divided into a treatment group (treated with Ninggan-Tiaozhong decoction and psychological intervention) and a control group (treated with Ninggan-Tiaozhong decoction),with 40 cases in each group and performed a therapy for 12 weeks.The clinical efficacy and the change of Symptom Checklist (SCL-90)and Self-Rating Anxiety Scale(SAS) before and after treatment were evaluated.Results After 12 weeks of treatment,the total effective rate was 90.0% in the treatment group,and 74.4% in the control group.The treatment group was better than the control group(x2=4.255,P<0.05).After psychological intervention,SCL-90 and SAS score (39.5±4.3,1.3± 0.6)was significantly reduced in the treatment group than the control group (51.4±3.2,1.5±0.3),(P<0.05).Conclusion The combination therapy of Ninggan-Tiaozhong decoction and psychological intervention used in CAG is effective to relieve symptoms and to improve life quality of patients.

Objective:To study the direct effects of gradient concentration inteiferon-a(IFN-a) on lymphoma cells line Daudi and Jur-kat and a group of 15 cases refractory lymphoma. Methods: The effects of IFN-a on the growth of tumor cells were assayed by MTT, apoptosis were measured by flow cytometty, TUNEL and electron-microscope, 15 refractory lymphoma cases were treated by local injection of IFN-a combination chemotherapy.Results: Low-dose IFN-a did not have any significant effects on growth of Daudi and Jurkat cells, high-dose IFN-a (10 000U/ml) not only have significant anti-proliferative effects with dependence of time and dosage but also can induce apoptosis on both Daudi and Jurkat cells. 5 patients achieved a complete remission and 7 patients achieved a partial remission, the overall response rate was 80% .Conclusion:IFN-a( 10 000 U/ml) had significant anti-proliferative effects and inducing apoptosis on lymphoma cells.Local injection of IFN-a is one of effective therapy on refractory lymphoma.

BACKGROUND:We attempt to explore a low-cost, simple and effective way to cryopreserve bone marrow mesenchymal stem cels at-80℃.
OBJECTIVE:To screen the optimal cryopreservation fluid for bone marrow mesenchymal stem cels and to verify the biological features of bone marrow mesenchymal stem cels after long-term cryopreservation.
METHODS: Bone marrow mesenchymal stem cels were cultured using adherent method and the biological features and purity of cels were detected using immunofluorescence method. Bone marrow mesenchymal stem cels were cryopreserved in the cryoprotectant medium containing low-sugar DMEM, fetal bovine serum and dimethyl sulfoxide at different proportions at-80℃ for a short term. Then, the optimal cryoprotectant was selected to storage the bone marrow mesenchymal stem cels. After 1, 3, 6 months of cryopreservation, the cels were resuscitated, cultured and passaged. Passage cels were identified immunofluorescence method to determine the biological features of bone marrow mesenchymal stem cels cryopreserved at-80℃.
RESULTS AND CONCLUSION:Cryoprotectant medium of 80% DMEM+10% fetal bovine serum+10% dimethyl sulfoxide was suitable for cryopreserving MSCs at -80℃, and resuscitated cels were able to proliferate in vitro, and passage normaly, indicating the cryopreserved bone marrow mesenchymal stem cels stil maintain the original biological activity.

Objective: To estimate the clinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolys-is agents in bone metastatic carcinoma. Methods: Seventy-one patients with bone metastatic carcinoma were divided into 2groups and treated with protocol A or B, respectively. The protocol A was a combination of chemotherapy with osteoblastpromoting and anti-osteolysis agents, the protocol B was a combination of chemotherapy with antiosteolysis agent only. Theefficacies of the 2 protocols were compared and studied. Results:The effect of A was more remarkable than that of B in re-lieving bone pain and enhancing bone repair. No severe adverse effect of these agents was found in therapy. Conclusion: Theclinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolysis agents in bone metastatic car-cinoma was definite, the osteoblast promoting agent as an effective adjtmctive agent can be used not only in osteoprosis butalso in bone metastatic carcinoma.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. However, due to its complex pathogenesis, there are no officially approved drugs for NAFLD treatment currently. Therefore, it is extremely urgent to find safe and effective anti-NAFLD drugs. Nowadays, lipid-lowering drugs are the main option for NAFLD therapy, but the clinical efficacy of chemical drugs is also very limited, as well as the frequent side effects or adverse reactions. Traditional Chinese medicine (TCM) has attracted more and more attention in the treatment of NAFLD due to its unique advantages through multiple targets and pathways with few side effects. In recent years, numerous studies have demonstrated that the imbalance of gut microbiota plays an important role in the occurrence and development of NAFLD. This review systematically summarizes the experimental and clinical evidences of TCM active compounds and TCM prescription involved in the regulation of intestinal flora in the treatment of NAFLD in recent years, so as to provide a reference for further exploring the pathogenesis of NAFLD and exploring TCM treatment methods.

Objective To evaluate results of double eyelid operations with different incisions.Methods 100 patientswere selected randomly from out-patients that accepted double eyelid operation.Half of them were objected to double eyelid operation through a palpebral marginal incision.Incision was designed along the palpebral margin,close to boots of eyelashes.Most of the subcutaneous tissues was cut and removed,and then dermis and tarsal plate were fixed with 5 stitches of suture.About 1-3 mm wide of skin along superior margin was removed reasonably.In another 50 cases.double eyelid operation was performed with conventional incision.Incision was designed 6-8 mm far from the palpebral margin.Most of the subcutaneous tissues was removed.and then dermis and tarsal plate were fixed with 5 stitches of suture.Results Postoperative results were evaluated 5 days and 1 month after operation respectively.Postoperative double eyelid shapes were all satisfled in two groups.Swollen eyedids and scar were more inconspicuous in the cases with the palpebral-marginal incision without impairment on eyelashes.Conclusion Compared with double eyelid operation with conventional incision,blepharoplasty with palpebral margin incision has the same results but with lighter impairment,milder hydropsia and more inconspicuous scar.The key point of this procedure is the fixation of dermis and tarsal plate,keeping a good radian of double eyelid line.
