Objective:To observe the clinical effect of tuina plus foot bath with Chinese medicine for patients with diabetic foot (DF) in early stage.Methods:A total of 70 patients with early-stage DF were randomly allocated by the random number table into two groups,with 35 cases in each group.Patients in the control group received conventional medication,while patients in the observation group received tuina plus foot bath with Chinese medicine on the basis of conventional medication.The clinical efficacy was compared after 2 courses of treatment.Results:After treatment,intra-group comparisons of ankle-brachial index (ABI) showed statistical significance in both groups (both P＜0.05).The curative rate was 83.3％ in the observation group,with the total effective rate of 96.7％,versus 29.4％ and 76.5％ in the control group,respectively,and the between-group comparisons showed statistical significance (both P＜0.05),indicating a better effect in the observation group.Conclusion:Tuina plus foot bath with Chinese medicine has a good therapeutic effect for DF patients in early stage.

Objective:To determine the difference of miRNA expression profiles in 6 types of human cancer cells by microarray technique.Methods:The microarray was prepared,with contained 210 oligonucleotides,including 206 probes complementary with human and mouse miRNA sequences and 4 positive control oligos.MiRNAs were extracted from HeLa(human cervical cancer epithelial cells),MCF-7(human breast cancer cells),A549(human lung adenocarcinoma cells),HT-29(human colonic cancer cells),ES-2(ovarian carcinoma cells),and K562(chronic myelogenous leukemia cells) cells and were labeled with Cy3 for hybridization to the miRNA microarray.The slides were scanned by ScanArrayTMExpress1.0 and images were analyzed by ScanArray3.0 and Cluster3.0;the results were confirmed by Northern blotting and RT-PCR.Results:Totally 115 miRNAs were found to be differentially expressed in the 6 cancer cell lines,with miR-21 expression up-regulated and miR-125b,let-7 expression down-regulated.The expression of miR-17-5p and miR-20a was in cluster and was more higher in ES-2 cells than in other cells.HeLa and MCF-7 cells were located on a single branch of the dendrogram in cluster analysis.Northern blotting showed that both pre-and miR-17-5p expressed in K562,pre-miR-17-5p was weakly expressed in A549 and ES-2 cells,and obvious pre-miRNA expression and weak miRNA expression were noticed in MCF-7,HeLa,and HT-29 cells.RT-PCR showed that expression of pre-miR-17-5p in K562 cells was higher than those in other cells.Expression of miR-21was high in all 6 cell lines and the highest expression was seen in A549 cells.Conclusion:Microarray can be used to detect miRNA expression files in cancer cells,which contributes to the study of the relation between miRNA and tumor.

Objective To investigate the effects of modafinil,a new wake-promoting agent,on simulated flight performance during 48 h sleep deprivation(SD).Method Six male healthy young volunteers were exposed to two periods of 48 h continuous wakefulness during the crossover experiment.In one period,three 200 mg doses of modafinil were given and in the other,separated by two weeks,matching placebos were administered.The SD time started from 8:00 of the first day to 8:00 of the third day.Drug was given at 0:00,16:00 of the second day and 0:00 of the third day.Flight performance in J7-E flight simulator was tested at 21:00 of the first day and 1,3,5,7 h after each drug administration.Result The scores of simulated flight performance in the placebo group decreased with time during SD and became significant at 1:00～7:00 of the third day.Numbers of errors increased with time during SD,especially in the left ascending turn stage and the descending & landing stages.Compared with the placebo,flight performance was significantly increased after the third administration of modafinil.Numbers of errors during 48 h SD and at 1:00～7:00 of the third day in modafinil group was 19% and 40% lower than those in placebo group respectively.Conclusion Simulated flight performance during 48 h SD is significantly improved after repeated administration of modafinil,especially when the impacts of SD and the circadian trough are combined.

OBJECTIVETo compare the difference in the clinical efficacy on premature ovarian failure (POF) between the acupoint catgut implantation combined with artifical periodic therapy and the simple artificial periodic therapy and explore its effect mechanism.

METHODSSixty-five patients of POF were randomized into the two groups. In a western medication group, 32 cases were treated with the artificial periodic therapy with the oral administration of medroxyprogesterone acetate tablets. In a catgut implantation + western medication group, 33 cases were treated with the acupoint catgut implantation combined with artificial periodic therapy. The acupoints of Neiguan (PC 6), Zusanli (ST 36), Guanyuan (CV 4) and Sanyinjiao (SP 6) were selected. The treatment was lasted for half a year and the follow-up visit was for another half a year in the two groups. Kupperman index was used to assess the improvements in the clinical symptoms. The levels of serum sexual hormones such as follicle stimulating hormone (FSH) and estradiol (E2) were evaluated of the patients in the two groups before and after treatment. The efficacy was compared between the two groups.

RESULTSThe scores of the clinical symptoms were all significantly improved after treatment and in the follow-up in the two groups (P < 0.01, P < 0.05). In the 6-month follow-up visit after treatment, the result in the catgut implantation + western medication group was better than that in the western medication group (8.17 +/- 1.19 vs 13.68 +/- 1.08, P < 0.01). FSH was reduced after treatment in the two groups (all P < 0.01) and E2 was increased (all P < 0.05). The curative and remarkably effective rates were 75.8% (25/33) and 81.8% (27/22) after treatment and in the follow-up visit in the catgut implantation + western medication group, which were better than 67.9% (19/28) and 53.6% (15/28) in the western medication group separately (P < 0.05, P < 0.01).

CONCLUSIONThe acupoint catgut implantation combined with artificial periodic therapy achieve the remarkable improvements in the clinical symptoms of POF in the patients and the better results as compared with the simple western medication therapy. The combined therapys efficacy is stable and the long-term efficacy is apparently superior. The effect mechanism is related to the improvements in the serum sexual hormone levels.

Objective To compare the effectiveness of medicated γintrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. Methods A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. Results At the 12th month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90th day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P<0.05). Among the bleeding and (or) spotting days, spotting days prolonged significantly. At the 12th month, spotting days of genefix-group andγ-group were (9.2±5.9) days and (8.5±4.6) days respectively, more than (5.2 ± 4.0) days of control group. The differences had statistical significance between IUD with control group (P<0.05), and had not between the two kinds of IUD (P>0.05). Conclusion The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.

Objective To study the influence of different body serum iron levels on follicle stimulating hormone (FSH),luteinizing hormone (LH) and uterine ovarian index,and explore the body serum iron level effects on female mice sexual maturity further.Methods 36 three weeks C57BL/6J female mice were randomly divided into the normal control group,strengthen-iron 1 group and strengthen-iron 2 group,12 cases in each group.The normal control group with normal diet(310mgFe/kg),strengthen-iron 1 group and strengthen-iron 2 group were given high -iron diets(respectively with 465mgFe/kg and 620mgFe/kg) after born 3 weeks.each group body,uterus and ovary mass after 2 weeks were checked;colorimetric method was used to detect the serum iron level;the serum follicle stimulating hormone (FSH) and luteinizing hormone(LH) were detected by chemiluminescent immunoassay.Results The body of mice serum iron levels,uterine ovarian index (uterine ovarian wet mass/body mass) and follicle stimulating hormone(FSH) level of strengthen-iron 1 group and strengthen-iron 2 group were higher than those of normal control group (F =9.11,11.11,7.09,all P ＜ 0.01).Luteinizing hormone (LH) level of the strengthen-iron group was higher than those of normal control group (F =3.89,P ＜ 0.05).Conclusion Uterine ovarian index,follicle stimulating hormone level and luteinizing hormone level were affected with increased serum iron level;It suggests that the increasing serum iron level can cause female mice sexual maturity in advance.
