To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

Objective To evaluate the capability of internal transcribed spacer (ITS) region sequencing analysis to identify clinical isolates of filamentous fungi.Methods A total of 267 filamentous fungi isolates collected from clinical specimens were analyzed by ITS region sequencing analysis.Alignment of acquired sequences with known sequences in GenBank and MycoBank was conducted to identify the species of those isolates.Results ITS sequences of the 267 isolates were amplified successfully.Among these isolates, 53.9％ (144/267) were identified to species level and 44.2％ (118/267) to genus level.Only five isolates were failed to be identified at genus level as they shared >95％ homology in ITS sequence with multiple genera.Conclusion ITS region sequencing analysis is preferred for identification of clinical isolates of filamentous fungi at genus level for its high universality and great capability.When species-level identification is required, some informative DNA markers besides ITS region should be included accordingly.

Objective To investigate the application of high frequency ultrasound in knee joint lesions of elderly patients with rheumatoid arthritis.Methods Fifty patients with rheumatoid arthritis were collected in Yangpu Hospital Affiliated to Tongji University from March 2015 to December 2016 as test group.Fifty healthy elderly people without knee joint lesion were randomly selected as control group.High frequency ultrasound was used to examine the patients in the test group and the Results of this examination were used to compare with those of the control group and observe four indexes: patellofemoral effusion,synovial thickness,cartilage thickness and blood flow in the lesion area.Results There was only a small amount of synovial fluid in the articular cavity in the control group,the thickness was (2.11± 0.94) mm,while the thickness of the test group was (10.33±2.74) mm,the difference was statistically significant (t=17.03,P<0.05);in the control group,there was no synovial hyperplasia,the thickness was (1.11±0.24) mm,while the thickness of the test group was (5.48±2.74) mm which was significantly higher than that of the control group (t=13.18,P<0.05);in the control group,the cartilage tissue was striated without echo band,the thickness was (1.76±0.29) mm,while the cartilage tissue of the experimental group had lesion,the thickness was (1.12±0.12) mm lower than that of the control group and the difference was statistically significant (t=6.44,P<0.05);in the control group,there was no blood flow signal in the joint cavity,while low-speed blood flow signal could be seen in the joint cavity of the test group,the difference was statistically significant (0 vs.96%,χ2=6.44,P<0.05).Conclusion High frequency ultrasonography is effective in the treatment of senile rheumatoid arthritis with high specificity,high sensitivity,low cost,high efficiency and simple operation and it is not subject to external conditions.Therefore,it is suitable for early examination of senile rheumatoid arthritis and clinical promotion.

Objective To screen and identify the anomously expressed proteins at protein level in colon mucosa of diarrhea-predominant irritable bowel syndrome(D-IBS)patients and healthy individuals.Methods Four D-IBS patients and four healthy individuals were included in the study.Biopsies of mucosa at the ileocecal junction and sigmoid colon were performed via colonoscopy.The specimens were cleaned with ice cold saline which contained 0.1% PMSF,and were snap frozen in liquid nitrogen.The two-dimensional gel electrophoresis(2-DE)was used to screen the anomously expressed proteins,and the two proteins which presented the greatest changes in each group were identified by mass spectrometry method.Results Proteomics maps of human colon mucosa were obtained successfully with 2-DE.Average protein spots were 336 in normal control group,and the matching rate among them was 92%,while in D-IBS group,the average protein spots were 426,and the matching rate was 95%.The average matching rate between the test group and the control group was 74%.It was found that the volume value of 24 proteins spots changed more than two folds.The protein expression was found to decrease in 3 spots and increase in 21 spots.Four proteins were chosen for analysis with mass spectrometry analysis.The two up-regulated proteins were identified as Immunoglobulin J chain and heat shock protein 27,while the other two down-regulated proteins were identified as hemoglobin beta subunit and fructose-bisphosphate aldolase A.Conclusion With 2-DE,proteomics maps of human colon mucosa have been obtained successfully.The proteome expressions of colon mucosa in D-IBS patients are remarkably different from that of the healthy individuals.The four identified proteins may play a certain role in the pathogenesis of D-IBS.

Objective To study the effect of myocardial ischemic preconditioning on activity of ATPase and creatine kinase(CK) in high blood fat rat. Methods High blood fat rat mode was established from SD rats.The rats were randomly divided into three groups: ischemic preconditioning(IPC), ischemic/reperfusion(I/R) and control group.The activity of CK in coronary outflow,the activity of malonyldialdehyde(MDA),superoxide dismutase(SOD),glutathione perodxidase(GSH-Px) and ATPase in myocardium were dectected. Results CK and MDA were significantly less in IPC group than those in I/R group.In IPC group,the activity of SOD,GSH-Px,Na~(+)-K~(+)-ATPase,Ca~(2+)-ATPase and Ca~(2+)-Mg~(2+)-ATPase were much higher than those in I/R group. Conclusion Myocardial ischemic preconditioning can protect high blood fat rat from ischemic/reperfusion injury.

To screen small molecule peptide specific binding to non-small cell lung cancer cell (A549) using the "one-bead one-peptide" combinatorial library. Twenty-nine positive beads binding to A549 cell were totally obtained after primary screening. Consensus peptide sequence of -NGXG-was identified by amino acid sequencing in ten beads. Peptide cNGQGEQc was re-synthesized on beads and further studied for its cell specificity, alanine scanning and site-directed deletion. The results showed that cNGQGEQc is specific for cell attachment to non-small cell lung cancer cells including A549, Calu-1 and H178, but not to other tumor cell lines. Both motif of -NGXG-and the length of six peptides are very important for A549 adhesion. Peptide cNGQGEQc labeled with FITC can specifically bind to A549 cell. In a blocking assay with anti-integrin antibodies(?1～6, ?v/?1～5), cell adhesion of A549 to peptide beads was obviously inhibited by integrin ?3 combining with any ? subunits. Results suggested that small molecule peptide cNGQGEQc can bind specifically to non-small cell lung cancer cell A549 via integrin ?3 on cell surface.

OBJECTIVETo explore the effect differences between twirling-rotating reinforcing and reducing technique of acupuncture on cardiac damage in spontaneous hypertensive rats (SHR).

METHODSSixty male 11-week-old SHR were randomly divided into four groups: a model control group (group A), a twirling-rotating reinforcing technique group (group B), a twirling-rotating reducing technique group (group C) and a needle retaining group (group D), 15 rats in each one. In addition, twelve male 11-week-old Wistar rats were used as a blank control group (group E). Acupuncture was not used in group A and group E, only with grasp, capture and binding stimulation that was also adapted in the rest groups. Rats in the group B were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reinforcing technique for 1 min and then the needles were retained for 9 min; rats in the group C were treated with acupuncture at "Taichong" (LR 3) by twirling-rotating reducing technique for 1 min and then the needles were retained for 9 min; rats in the group D were treated with acupuncture at "Taichong" (LR 3) but without any technique and then needles were retained for 10 min. Before and after acupuncture, blood pressure monitor was used to measure the rats' systolic pressure and diastolic pressure every 6 days. Twenty-eight days after the treatment, HE and Masson staining were adopted to observe the status of left ventricular hypertrophy and myocardial fibrosis. ELISA method was applied to test the content of endothelin-1 (ET-1). PCR semiquantitative method was used to analyze Type I and III collagen mRNA in the left ventricular.

RESULTS(1) Blood pressure: after the treatment, the systolic pressure and diastolic pressure were both increased in the group A and the group B (P < 0.05); while the two pressures were both lowered in the group C and the group D (P < 0.05), which was more obvious in the group C (P < 0.05). (2) According to HE and Masson staining, except for the group E, the myocardial hypertrophy and fibrosis could be found in the rest groups, in which the group C was the modest, followed by the group D, while the group A and the group B were more severe. (3) Concentration of ET-1: there were differences of concentration of ET-1 among 5 groups (P < 0.05), and the concentration value from high to low was the group A, B, C, D and E. (4) Type I collagen mRNA: the difference of level of Type I collagen mRNA between group C and D was not statistically significant (P > 0.05); compared with the group A and B, the level was lower in the group C; the level was the lowest in the group E. Type III collagen mRNA: the difference between the group A and B was not statistically significant (P > 0.05); compared with the group A, B and D, the level was lower in the group C.

CONCLUSIONThe twirling-rotating reducing could reduce the systolic pressure and diastolic pressure in SHR, effectively prohibit the production of ET-1 and expression of Type I and III collagen mRNA, and it has more obvious inhibiting effect on Type III collagen mRNA. There is biological effect difference between twirling-rotating reinforcing and reducing technique.

Micro- and integrated biosensor provides a powerful means for cell electrophysiology research. The technology of electroplating platinum black on the electrode can uprate signal-to-noise ratio and sensitivity of the sensor. For quantifying analysis of the processing method of electroplating process, this paper proposes a grid search algorithm based on the Monte-Carlo model. The paper also puts forward the operational optimization strategy, which can rapidly implement the process of large-scale nanoparticles with different particle size of dispersion (20-200 nm) attac- hing to the electrode and shortening a simulation time from average 20 hours to 0.5 hour when the test number is 10 and electrode radius is 100 microm. When the nanoparticle was in a single layer or multiple layers, the treatment uniformity and attachment rate was analyzed by using the grid search algorithm with different sizes and shapes of electrode. Simulation results showed that under ideal conditions, when the electrode radius is less than 100 /m, with the electrode size increasing, it has an obvious effect for the effective attachment and the homogeneity of nanoparticle, which is advantageous to the quantitative evaluation of electrode array's repeatability. Under the condition of the same electrode area, the best attachment is on the circular electrode compared to the attachments on the square and rectangular ones.
