With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Abstract: Objective　To explore the antiviral effect of baricitinib in the SARS-CoV-2 infection and influence on cytokine levels. Methods　Calu-3 cells were infected with SARS-CoV-2 at MOI of 0.1, and the levels of inflammatory cytokines (IL-6, IL-8, TNF-α and IL-1β), interferon β (IFN-β) and interferon-stimulated gene, IFIT2 in the infected cells were analyzed by qRT-PCR methods. At the same time, Calu-3 cells were infected with SARS-CoV-2 (MOI=0.1) after being treated with baricitinib for 2 hours. Cells were collected at 0, 24, 36, and 48 hours, and analyzed for the mRNA of the above genes in the drug-treated and untreated groups. Results　The mRNA levels of IL-6, TNF-a, IL-1β, IFN-β and IFIT2 in Calu-3 infected by SARS-CoV-2 cells were increased significantly. These cytokines were increased by nearly 100-fold post-infection 48 h compared with the control (P<0.000 1), and continued to increase with the infection time (P<0.001 or P<0.000 1). The increase of IL-8 mRNA level was not as significant as IL-6, TNF-α, IL-8, IL-1β, but it also showed a 2-4 folds increase. Baricitinib does not affect the level of viral RNA in Calu-3 cells after SARS-CoV-2 infection (P>0.05). However, baricitinib can significantly inhibit the up-regulation of IL-6 and TNF-α levels induced by SARS-CoV-2 infection (5.25-fold and 3.90-fold down-regulation, respectively, P<0.01), and has little effect on the levels of IL-8 and IL-1β . In addition, the drug could also significantly down-regulate the increase in IFN-β and IFIT2 levels caused by viral infection (10.51-fold and 90.78-fold down-regulation, respectively, P<0.000 1). Conclusions　Baricitinib inhibits the release of inflammatory cytokines to some extent, but it drastically down-regulates the expression of interferons and interferon-stimulated genes (ISGs), and has limited antiviral effect on SARS-CoV-2. Considering that interferon signal pathways play important roles on viral infection, caution should be exercised when using baricitinib to treat COVID-19 patients.

BACKGROUND:Traditionally, forced expiratory volume in one second (FEV1) was used to evaluate exercise response of patients with asthma; however, patients obviously had panting after exercise, so FEV1 was affected commonly. Impulse oscillometry (IOS) is a new technique for measuring respiratory impedance that do not require maximal inspiration and forced expiration.OBJECTIVE: To study airway resistance with IOS before and after exercise in healthy and asthmatic patients and investigate the significance of exercise excitation and IOS assessment.DESIGN: Synchronically non-randomized case contrast study.SETTING: Department of Respiratory Medicine, East Hospital Affiliated to Tongji University.PARTICIPANTS: A total of 14 male patients with bronchial asthma who were regarded as the asthmatic group were selected from Department of Respiratory Medicine of Shanghai East Hospital from January to October 2006. They were in a clinical stationary phase. Another 14 male healthy subjects were selected as the control group and ages of all subjects ranged from 29 to 50 years. All subjects provided the confirmed consent.METHODS: IOS was used to measure basic value of respiratory resistance, and then subjects underwent exercise challenge. Nose of subjects was clipped breathing through mouth. Within 3-4 minutes, heart rate was increased to 90% and maintained for 6 minutes during challenge. Respiratory resistance was repeatedly measured at 1, 5, 10, 15 and 20 minutes after exercise, including airway hyperresponse (AHR), total respiratory resistance, central resistance, peripheral resistance and resonance frequency at 5, 20 and 35 Hz of pulse frequency, elasrtic resistance and inertia resistance (X5 and X35) at 5 and 10 Hz of pulse frequency. In addition, difference of AHR at 5 and 35 Hz was calculated, and change ratios of both Rcentral and Rperipheral were calculated as (highest value after exercise-baseline value)/baseline value × 100%.MAIN OUTCOME MEASURES: Basic value of respiratory resistance by using IOS and exercise challenge test.RESULTS: All 14 patients with bronchial asthma and 14 healthy subjects were involved in the final analysis. Peripheral resistance (Rperiphera) was significantly higher than central resistance (Rcentral) in asthmatic patients (P ＜ 0.01). The maximal increase of respiratory impedance occurred from 5 minutes to 10 minutes after exercise in asthmatics. Resonance frequency (Fres) of asthmatics before and after exercise was significantly increased than that of controls (P ＜ 0.01).Change ratios of Fres from asthmatics were higher than that from control group (P ＜ 0.01). After challenge, R5, R5-R20,Zrespir and X5 from asthmatics changed significantly than that from controls (P ＜ 0.01). The increment change value of After exercise Zrespir increased significantly, because obstruction of small bronchi during expiration and impedance increased abruptly. Air trapping was expressed in VT-Zrespir graph in 57.1% patients. There was no difference in the VT-Zrespir graph of controls before and after exercise.CONCLUSION: The main site of airflow obstruction was in small airways in asthmatics after exercise challenge. The general acceptance of IOS method was good among the asthmatic patients. The airway response of exercise challenge may be assessed more accurately with IOS that do not require a maximal inspiration and forced expiration.

BACKGROUND: Mesenchymal stem cells are the stem cells that possess the capability for self-renewal and multi-directional differentiation. Umbilical cord is the tissue outside the embryos and would be fallen off after parturition. In addition, it has wide source and no ethical restriction, so it is promising to be the first choice for mesenchymal stem cells. OBJECTIVE: To detect the surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) prior to and after cryopreservation and resuscitation. METHODS: After isolation and culture, morphology of the primary, P4 and P8 hUCMSCs was observed prior to cryopreservation and after resuscitation. Surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of primary, P4, and P8 hUCMSCs were detected through the use of flow cytometry prior to cryopreservation and after resuscitation RESULTS AND CONCLUSION: hUCMSCs prior to cryopreservation and hUCMSCs of different passages after resuscitation present the same phenotype, i.e., positive for CD29, CD44, CD49e, CD73, and CD90, and negative for CD34, CD45, CD271. These findings suggest that primary hUCMSCs do not present changes in surface markers after cryopreservation and resuscitation.

Objective To investigate the effect of advanced oxidation protein products (AOPPs) on human renal tubular epithelial cells(HK-2) autophagy.Methods HK-2 cells were stimulated with AOPPs.RT-qPCR and Western blot were used to determine the expression of autophagy related protein LC3-Ⅱ/LC3-Ⅰ,Beclin1 and p62;Western blot was utilized to examine the activation of p38 MAPK pathway.Then p38 MAPK inhibitor (SB203580) was added and co-processed with AOPPs.The change of autophagy was observed Also,autophagy inducer rapamycin was added and co-processed with AOPPs.RT-qPCR and Western blot were used to detect the expression of cell cycle inhibitory protein p27.The cell total protein level was detected by the bicinchoninic acid (BCA) method.The hypertrophy change was observed.Results AOPPs down-regulated the expression of LC3-Ⅱ/LC3-Ⅰ and Beclin1,up-regulated expression of p62 and activated p38 MAPK pathway;in comparison with the AOPPs alone treatment group,the expression of LC3-Ⅱ/LC3-Ⅰ and Beclin in the SB203580 co-processing group was increased,while p62 was decreased;the p27 expression and cells total protein in the sirolimus co-processing group were down-regulated.Conclusion AOPPs inhibits the autophagy of HK-2 cells by activating p38 MAPK pathway and the autophagy inhibition participates in HK-2 cell hypertrophy.
