Objective:To study the expressions of hepatocyte growth factor (HGF) and basic fibroblast growth factor (bFGF) in fresh and two preserved amniotic membranes (AM),and to explore their biological vitality.Methods:The amniotic membranes from the healthy puerperia with abdominal delivery were randomly divided into three groups:fresh group,DMEM/glycerol preserved group at -80℃ and glycerol preserved group at 4℃ (for 1 and 3 months).Immunohistochemical method was used to investigate the changes in the expressions of HGF and bFGF among the three groups.Results:HGF and bFGF were distributed in the epithelium of AMs mostly.The expressions of HGF in both preserved AMs for 1 and 3 months decreased significantly compared with fresh AM (P

Objective　To study on effects of mVEGF and anti-VEGF antibody during cultured HUVEC proliferation in vitro.Methods　Endothelial cell proliferation was assayed using human umbilical vein endothelial cells stimulated with mVEGF and with CIA joint extracts and was used　　3　　H-TaR incorporation.Results　The anti-VEGF neutralizing antibody can inhibit the proliferation of HUVEC stimulated with mVEGF and with CIA joint extracts,whose suppression percents were 72.2% and 69.9%,respectively.Conclusion　mVEGF specifically promotes the growth of vascular endothelial cells.During early stage of CIA development,expression of VEGF in the joint increases and VEGF is expressed biologically active and can be inhibited by anti-VEGF neutralizing antibody.

OBJECTIVE:To study the effects of Anzi mixture on Toll like receptor 4(TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear facter-κB(NF-κB)signaling pathway of antiphospholipid antibodies(APA)positive abortive mice,and to inves-tigate the mechanism of anti-APA positive abortion. METHODS:BALB/c mice(female)were randomly divided into blank control group,model group,aspirin group (positive control,0.0195 g/kg) and Anzi mixture low-dose,medium-dose and high-dose groups (37.7,75.4,150.8 g/kg,calculated by crude drug),with 10 mice in each group. Except for blank control group,other groups were given human β2-glycoprotein Ⅰ as derivant to establish APA positive abortion model. From the first day of pregnancy, treatment groups were given relevant medicine intragastrically,and blank control group and model group were given constant vol-ume of normal saline intragastrically,once a day,for consecutive 9 d. mRNA and protein levels of TLR4,myeloid differentiation 2 (MD2),MyD88 and NF-κB in placental tissue of mice were determined by RT-PCR and immunohistochemical method. RE-SULTS:Compared with blank control group,mRNA and protein expression of TLR4,MD2,MyD88 and NF-κB in placental tis-sue were increased markedly in the model group(P<0.01). Compared with model group,mRNA and protein expression of TLR4, MD2 and MyD88 in aspirin group and Anzi mixture low-dose and medium-dose groups were decreased significantly as well as the protein expression of TLR4 in Anzi mixture high-dose group and the protein expression of NF-κB in all medicine groups(P<0.05 or P<0.01). mRNA expression of TLR4 and MD2 and the protein expression of MD2 and MyD88 in Anzi mixture low-dose groups were lower than those in aspirin group (P<0.05 or P<0.01). CONCLUSIONS:Anzi mixture can inhibit TLR4/MyD88/NF-κB signaling pathway of APA positive abortive mice,which may be one of anti-APA positive abortion mechanisms.

Objective To observe the efficacy and prognosis of aconite-cake-partitioned moxibustion plus acupuncture in treating peptic ulcer.Method Thirty-four patients in the treatment group were intervened by aconite-cake-partitioned moxibustion plus acupuncture, while thirty-three patients in the control group were by Omeprazole Enteric-coated Capsules. The clinical efficacy, the effect on ulcer under gastroscope and Hp, and the therapeutic efficacy 12 months after the intervention were evaluated.Result The total effective rate was 91.2% in the treatment group versus 72.7% in the control group, and the difference was statistically significant (P<0.05). For ulcer by gastroscopy, the total effective rate was 85.3% in the treatment group versus 69.7% in the control group, and the difference was statistically significant (P<0.05). After intervention, the Hp level didn’t show significant change (P>0.05). The relapse rate of the control group was higher than that of the treatment group 12 months after the intervention.Conclusion Aconite-cake-partitioned moxibustion plus acupuncture can produce a higher efficacy than Western medication in treating peptic ulcer.

Objective To observe the therapeutic efficacy of acupuncture plus moxibustion in treating chemoradiotherapy-induced leukopenia in patients with malignant tumors.Method A total of 120 patients with malignant tumors who presentedleukopenia during receiving chemoradiotherapy were randomized into two groups. Sixty cases in the treatment group were intervened by acupuncture plus moxibustion; sixty cases in the control group were intervened by oral administration of Batilol tablets and Leucogen tablets.The peripheral white blood cell (WBC) count in the two groups was detected on treatment day 3, 7, 14, 21, and 28.The clinical efficacies of the two groups were compared.ResultThe WBC started toincreaseafter 1-week treatment in thetreatment group (P<0.05) and the increase was statistically significant after 2-week treatment (P<0.01); in the control group, the WBC started to increase after 2-week treatment (P<0.05)and the increase was statistically significant after 3-week treatment (P<0.01); the effect of increasing WBC was more significant in the treatment group compared to the control group (P<0.05,P<0.01).The total effective rate was 90.0% in the treatment group versus 53.3% in the control group, and the between-group difference was statistically significant (P<0.01).Conclusion Acupuncture plus moxibustion can produce a significant efficacy in treating leukopenia induced by chemoradiotherapy.

Objective To compare the clinical effect of C3F8 and air tamponade after vitrectomy for the treatment of idiopathic macular hole (IMH).Methods A total of 54 eyes of 54 patients with IMH that had undergone 23G pars plana vitrectomy with internal limiting membrane peeling were retrospectively studied.All patients received optical coherence tomography ()CT) examination and the best corrected visual acuity (BCVA).They were divided into 2 groups.26 eyes in group A were filled with air and 28 eyes in group B were filled with C3F8.In group A,6 eyes at stage Ⅱ,20 eyes at stage Ⅲ,the minimum diameter (Dmin) of macular hole in 14 eyes was less than 400 μm,and in the other eyes was larger than 400 μm.In group B,10 eyes at stage Ⅱ,18 eyes at stage Ⅲ,the Dmin of macular hole in 15 eyes was less than 400 μm,and in the other eyes was larger than 400 μm.The differences of age,course of the disease,BCVA,fundus diameter,Dmin,height,index,diameter of outer retina diameter (Dord) between the two groups were not significant (P＞0.05).The basic data before surgery and the closure rate,BCVA,Dord 1 month after surgery between two groups were compared.Results At 1 month after surgery,the IMH closure rate was 100.0％ in group A and 92.9％ in group B,the difference between these two groups was not significant (P=0.491).The closure rate of eyes with Dmin＜400 μm were both 100.0％ in two groups,and the closure rate of eyes with Dmin＞400 μm were 100.0％ in group A and 84.6％ in group B.There was no statistically significant differences between two groups (P =0.480).The mean BCVA of two groups were 0.35±0.22 and 0.33 ±0.16 respectively.The mean Dord were (782.2 ± 478.0) μm and(792.1 ± 432.7) μm respectively.All cases got better BCVA (t=-7.310,-10.506;P＜0.01) and shorter Dord (t=6.704,7.770;P＜0.01).But there was no statistically significant differences between groups 1 month after surgery in BCVA and Dord (t =0.381,0.800;P =0.705,0.937).Conclusion Air tamponade after vitrectomy has the same efficacy as C3 F8 tamponade in the treatment of IMH.

Multiple myeloma is a malignancy of plasma cells,which is still incurable now.Despite dramatic improvement of the response rate and overall survival have been made due to the application of target therapy and stem cell transplantation,the treatment effect is difficult to maintain,nearly all patients will eventually relapse and become refractory.At relapse,the challenge is to select the appropriate treatment for each patient.The decision will be both disease-dependent and patient-dependent.
