ABSTRACT

Flexible variable stiffness actuator is divided into four categories including elastic element, pneumatic element, electric-magnetic element and intelligent material. It is gradually applied in rehabilitation robot. It could adapt the change of patient's impedance in the upper and lower limb rehabilitation robots, ensure the safety of the wearer in the exoskeleton, and improve the biomimetics in the prosthesis. Variable stiffness driving mechanism for rehabilitation robot still has some disadvantages. It is proposed to have compact structure, low power consumption, good stiffness characteristics, high response rate and progressive output torque curve, etc.

ABSTRACT

Posttransplant lymphoproliferative disease (PTLD) is a series of heterogeneous lymphoproliferative diseases and a severe complication after solid organ transplantation in children. Over 70% of PTLD is associated with Epstein-Barr virus (EBV). EBV-related B-cell lymphoma is also the main malignant tumor after pediatric organ transplantation. EBV-related PTLD is still a challenge in pediatric solid organ transplantation, which is mainly caused by immune function damage induced by immune suppression after transplantation. However, the specific mechanism remains elusive. In recent years, biomarkers have been developed to guide the diagnosis and individualized treatment of EBV-related PTLD, which possesses excellent application prospect. In this article, research progresses on the incidence of EBV-related PTLD in solid organ transplantation and its biomarkers were reviewed, aiming to explore novel ideas for clinical diagnosis and treatment.

ABSTRACT

Whitmania pigra is the most widely distributed species of leeches in the market. In this study, the effect of heavy metal lead pollution on the anticoagulant activity of Wh. pigra was studied and the potential mechanism was explored. Pb(NO_3)_2 was used to contaminate the breeding soil which was then used to rear Wh. pigra for 50 days(lead-contaminated group, LC group), and meanwhile the blank control group(CG group) was set. Proteins were extracted from the obtained leech samples, and the differentially expressed proteins between LC and CG groups were analyzed by label-free proteomics technology. In this study, a total of 152 differentially expressed proteins were screened out, of which 93 proteins were up-regulated and 59 proteins were down-regulated in LC group. Bioinformatics analysis showed that the biological processes enriched with the differentially expressed proteins were mainly vesicle-mediated transport and transport positive regulation; the enriched cell components were mainly endocytosis vesicles and apical plasma membrane; the enriched molecular functions mainly included carbohydrate binding. The differentially expressed proteins were enriched in 76 KEGG pathways, which mainly involved metabolic pathways, biosynthesis of secondary metabolites, and bacterial invasion of epithelial cells. In this study, two differentially expressed proteins with Antistasin domain were presumed, which provides reference for further exploring the regulatory mechanism and signal transduction underlying the effect of lead pollution on the anticoagulant activity of leech.

ABSTRACT

In this experiment, an ultra-high performance liquid chromatographytandem triple quadrupole mass spectrometry was established for the determination of caffeine in commercially available Ginkgo Folium. The samples were extracted by ultrasonic method with methanol, and separated on Waters CORTECS T3 column(2.1 mm×100 mm, 2.7 μm), with mobile phase of 0.1% formic acid solution-0.1% formic acid acetonitrile solution for gradient elution, at flow rate of 0.3 mL·min~(-1); column temperature of 30 ℃, and injection volume of 2 μL. Mass spectrometry was conducted at ESI~+ multiple reaction monitoring(MRM) mode; quantitative analysis was conducted with external standard method. The results showed that in the range of 0.099 6-9.96 ng·mL~(-1), there was a good linear relationship between the mass concentration of caffeine and the peak area, R~2=0.999; the average recovery was 84.51%, with RSD of 6.2%. The results of precision, repeatability and stability showed that the RSD was 5.1%, 5.9%, 7.2%, respectively. The content range of caffeine in 10 batches of Ginkgo Folium was 1.52-60.86 μg·kg~(-1). In conclusion, this method is accurate, reliable and reproducible, which provides a reference for the safety study of Ginkgo Folium.

ABSTRACT

Hydrogen peroxide (H2O2) plays a significant role in regulating a variety of biological processes. Dys-regulation of H2O2 can lead to various diseases. Although numerous fluorescent imaging probes for H2O2 have been reported, the development of H2O2 ratiometric fluorescent probe with large Stokes shift re-mains rather limited. Such probes have shown distinct advantages, such as minimized interference from environment and improved signal-to noise ratio. In this work, we reported a new pyrene-based com-pound Py-VPB as H2O2 fluorescent probe in vitro. The probe demonstrated ratiometric detection behavior, large Stokes shift and large emission shift. In addition, the probe showed high sensitivity and selectivity towards H2O2 in vitro. Based on these excellent properties, we successfully applied Py-VPB to the visualization of exogenous and endogenous H2O2 in living cells. Cell imaging study also showed that our probe was localized in the mitochondria. We envision that the probe can provide a useful tool for unmasking the biological roles of mitochondrial H2O2 in living systems.

ABSTRACT

Objective::Based on gene array technology, gene set enrichment analysis (GSEA) and immune infiltration analysis were performed on chip data of intracranial aneurysm (IA) mRNA expression profile, in order to provide theoretical basis for understanding the formation mechanism of IA. Method::The GSE75436 raw data were obtained from the gene expression omnibus (GEO). GSEA of biological process (BP) in gene ontology (GO) and Kyoto gene and genome encyclopedia (KEGG) signaling pathways were analyzed for gene expression profile by R software. The CIBERSORT deconvolution method was used to analyze the infiltration ratio of 22 types of immune cells in the expression profile. And COREMINE database was used to predict traditional Chinese medicines (TCMs), which were significant correlation with the enrichment result. Result::The GSEA results showed that the changes in gene expression of IA samples mainly involved in the regulation of cytokines, activation and differentiation of leukocyte, inflammatory immune response and other processes. The infiltration matrix analysis of immune cells showed that mast cells resting and neutrophils were significantly reduced in IA samples. The comparison of paired samples showed that mast cells and natural killer cells (NK cells) were significantly activated in the IA samples of the same individual, while neutrophils and T cells CD4 naive were significantly reduced. Through COREMINE prediction, it was found that Stephaniae Tetrandrae Radix was correlated with the activation of granulocytes, Sapindi Mukorossi Semen and Pistaciae Chinensis Cortex were correlated with the activation of neutrophils, Trichosanthis Semen, Paeoniae Radix Alba and Ligustri Lucidi Fructus were correlated with the cytotoxicity mediated by NK cells. Conclusion::Activation of mast cells and NK cells are closely associated with the occurrence and development of IA. The inflammatory immune processes and pathways such as nucleotide-binding oligomerization domain (NOD)-like receptor (NLR) signaling pathway and cytotoxicity mediated by NK cells may be important factors in the pathogenesis of IA, and TCMs such as Stephaniae Tetrandrae Radix may be the potential molecular drug sources.

ABSTRACT

BACKGROUND@#Knee osteoarthritis (OA) is a major cause of disability among the older adults. Few treatments are safe and effective. Moxibustion is commonly used in treating knee OA in Chinese medicine (CM). CO Laser moxibustion device is a substitute for traditional moxibustion, which mimics the effects of traditional moxibustion. More data are needed to support its application in knee OA.@*OBJECTIVE@#ObjectiveThe trial aims to assess the effect and safety of CO laser moxibustion in patients with knee osteoarthritis compared with a sham control.@*METHODS@#This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial. A total of 392 participants were recruited and assigned to the CO laser moxibustion group and sham laser moxibustion group with a 1:1 ratio at 6 outpatient clinics in Shanghai, China. Participants in both groups received treatment at the affected knee(s) at the acupuncture point Dubi (ST 35) and an Ashi point. There were 3 sessions per week for 4 weeks, and an additional 20-week follow-up. Primary outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores at week 4. Secondary outcomes were WOMAC function score, stiffness score and overall score, VAS pain, Short-Form heath survey (SF-36), and patients' global assessment. The serum levels of cytokines involved in progress of knee OA were explored. Safety was assessed during the whole trial. Masking effectiveness was assessed by both participants and treatment providers.This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial.

ABSTRACT

Objective To evaluate the clinical value of lymphocyte subset classification in the diagnosis of active pulmonary tuberculosis in renal transplant recipients. Methods Clinical data of 52 recipients undergoing renal transplantation were retrospectively analyzed. According to the results of imaging and etiological examination, 52 recipients were divided into the stable group(n=19), tuberculosis group (n=9), bacteria group (n=12) and fungi group (n=12), respectively. The renal function of recipients was compared, and the proportion and absolute value of lymphocyte subset were analyzed and compared among four groups. The diagnostic value of lymphocyte subset classification for active pulmonary tuberculosis after renal transplantation was evaluated. Results Compared with the stable group, the levels of blood urea nitrogen and serum creatinine in the tuberculosis group, bacteria group and fungi group were significantly increased (all P < 0.05). The proportion of CD3+, CD8+, CD4+, natural killer (NK) cells and CD19+ lymphocyte subsets were not significantly different (all P>0.05). And the absolute values of CD3+, CD8+, CD4+, NK cells and CD19+ lymphocyte subsets were significantly decreased (all P < 0.05). The proportion of CD8+ lymphocyte subset in the tuberculosis group and fungi group was significantly higher than that in the bacteria group (both P < 0.05). The optimal cut-off value of CD8+ lymphocyte subset ratio in the differential diagnosis of active pulmonary tuberculosis and bacterial pneumonia was 33.27%, and the sensitivity and specificity were 0.889 and 0.833, respectively. The area under the curve (AUC) was 0.880. Conclusions The classification of lymphocyte subset can provide auxiliary diagnostic basis for differential diagnosis and individualized treatment of active pulmonary tuberculosis and bacterial pneumonia in renal transplant recipients.

ABSTRACT

OBJECTIVE@#To analyze the characteristics of the temperature-time curve in warm needling manipulation with the acupuncture needles made of copper, silver, gold and stainless steel and explore the applicable temperature range and most suitable needle materials of warm needling manipulation in clinical practice.@*METHODS@#A total of 10 healthy subjects were included. Using the digital thermometer, with different moxibustion dose (1.2 g or 1.5 g, moxa), the temperature was measured at the site where the skin contacts with the needle body during the warm needling manipulation with stainless steel needle, copper needle, gold needle and sliver needle separately. The initial heat pain threshold (the temperature when hot feeling started) and the burning pain threshold (feeling very hot but tolerable) were recorded when using the different needles mentioned above. Through the subject questionnaire, the comfort degree, the heat sensation, the adverse reaction and the acceptability to warm needling manipulation with the different needles were investigated.@*RESULTS@#During the warm needling manipulation, the initial heat pain threshold was (42.8±2.7) ℃ and the burning pain threshold was (46.7±2.9) ℃. The strongest warm stimulation was presented in the warm needling manipulation with 1.5 g moxa and silver needle and the highest temperature was (55.5±6.3) ℃, followed by (52.9±4.2) ℃ with 1.2 g moxa and silver needle, (46.6±3.7) ℃ with 1.5 g moxa and gold needle, (46.6±1.9) ℃ with 1.5 g moxa and copper needle, (43.1±1.5) ℃ with 1.2 g moxa and copper needle and (41.7±0.9) ℃ with 1.5 g moxa and stainless steel needle. The sequence of the maintaining time of the initial heat pain threshold over 43℃ was 480 s with silver needle and 1.5 moxa, 325 s with silver needle and 1.2 g moxa, 270 s with gold needle and 1.5 g moxa, 185 s with copper needle and 1.5 g moxa, 42 s with copper needle and 1.2 g moxa and 0 s with stainless steel needle and 1.5 g moxa successively. The heat score graded by the subjects to the warm needling manipulation with different needles, from high to low, was presented in the manipulation with 1.5 g moxa and silver needle, 1.2 g moxa and silver needle, 1.5 g moxa and copper needle, 1.5 g moxa and gold needle, 1.2 g moxa and copper needle and 1.5 g moxa and stainless steel needle. The VAS score was different significantly in comparison among the six needles in warm needling manipulation (<0.001). The comfort degree of the subjects in the warm needling manipulation with silver needle and 1.5 g moxa was significantly lower than the warm needling manipulation with the other 5 materials (<0.05). Three subjects complained that the warm needling manipulation with silver needle and 1.5 g moxa was too hot to be tolerable and the most of subjects were willing to accept warm needling manipulation with these 6 materials (acceptability 70.0% to 100.0%). Except blisters presented in 9 subjects after warm needling manipulation with silver needle and 1.5 g moxa, no severe adverse reaction occurred in warm needling manipulation with 6 materials.@*CONCLUSION@#In the warm needling manipulation in the human body, the initial heat pain and the burning pain threshold were 43 ℃ and 47 ℃ respectively, which is the applicable temperature range of moxibustion in clinical practice. The warm needling manipulation with silver needle induces a quite strong heat stimulation and the discomfort may be caused when the temperature is exceeded to some threshold. The warm needling manipulation with copper needle generates the onset temperature, without inducing adverse reactions, e.g. discomfort and burning in the subjects.

ABSTRACT

Orthotopic liver transplantation (OLT) was first implemented by Starzl in 1963.With the development of liver transplantation,Tzaris was the first to report piggyback liver transplantation (PBLT) in 1989.The fundamental difference between OLT and PBLT:end to end vascular anastomosis between the donor and recipient is performed after diseased liver resection with the posthepatic inferior vena cava in OLT,while PBLT is to preserve the recipient's hepatic vein and end to end vascular anastomosis between interior vena cava of donor and shaped hepatic vein is performed.However in the clinical practice,the above two techniques cannot meet the needs of clinical liver transplantation technology.Since 1993 the author has implemented a series of improvements in liver transplantation technology based on PBLT and performed ameliorated piggyback liver transplantation (APBLT).This article focuses on the technical characteristics and clinical application of APBLT.

ABSTRACT

The positive human leukocyte antigen (HLA) antibody present in kidney transplant recipients affects both surgery and rejection, and also affects the long-term survival of the transplanted kidney. During the third kidney transplant, bilateral axillary fossa and iliac vessel were destroyed. It was very difficult for selection or separation of surgical vessels because the adhesions and scar formation was easy to damage blood vessels and intestinal tubes. A case with strong positive HLA antibody undergoing the third kidney transplant in our hospital was successfully solved the problems, such as less transplant space and vascular scar adhesion. Rituximab, rabbit anti-human thymocyte immunoglobulin, and methylprednisolone treated-antibodies were used in the operation. The immune function test was used to develop individualized treatment after the operation. The postoperative creatinine and urine volume tended to be stable, and the 16-month follow-up renal function was good.

ABSTRACT

In the paper, the study was reviewed on the infrared temperature characteristics of acupoints in recent 10 years. CNKI, WANFANG, VIP, SciVerse ScienceDirect and Springer databases were retrieved, with"infrared thermal imaging" and "acupoint" as the key words. The retrieving time was from January 1, 2006 to December 31, 2016. Totally, 468 relevant papers were searched and 169 papers of them were read carefully on acupoint infrared temperature. In terms of physiological condition, pathological condition and the stimulation methods such as acupuncture, moxibustion,, embedding therapy and cupping therapy, the general situation was reviewed on the infrared temperature characteristics of acupoints separately. It was found that the study on infrared temperature characteristics of acupoints in physiological condition was limited and the characteristics discovered were not enough to systematically review the physiological and physical properties of acupoints. The study in terms of the pathological condition objectively reflected the effects and rules of diseases. It was showed in the study of acupoint infrared temperature characteristics after stimulation that the changes of infrared thermal imaging tempe-rature at some specific region induced by different therapies and parameters might be used to deduce the potential mechanism and optimal parameters or schemes of intervention method and contributed to the formation and deve-lopment of quantitative diagnosis and treatment. The authors believe that the study on infrared temperature characteristics of acupoint provides the active significance in the exploration on the physiological and physical characteristics of acupoint, the effects and rules of diseases as well as the quantitative diagnosis and treatment.

ABSTRACT

TheMeridian and Acupoint Science is a basic course in the major of acupuncture-moxibustion and tuina. We applied target-guided teaching method in teaching this course to evoke student's interest in studyingMeridian and Acupoint Science through initiative guidance, and boost student's initiative and enthusiasm by exhibiting the teaching targets. During the practice, we emphasized the specification of each unit target, around which we adopted various methods; meanwhile, we also focused on prompt evaluation, based on which necessary adjustments would be made to approach the targets. Teachers should act as guider, maintainer and promoter in class, rather than transmitter, to help students to study positively rather than passively listen. Via this kind of teaching reform, students not only obtained knowledge, but also enhanced their capability and feelings.

ABSTRACT

Auto liver transplantation (ALT) has been tremendously popular in hepatic surgery for the liver masses due to lack of enough donor for allogeneic transplantation of liver.But ALT remains stagnant because it is technically more difficult than liver transplantation.Much difficulties in this field lying ahead.Related surgical technical requirements for surgeons operating ALT,complications,difficult liver resection,hypothermic liver perfusion,veno-venous bypass,ex vivo ECMO perfusion and liver trim,assess the quality and volume of autoplast,autoplast implant and vascular anastomosis.On the other hand,the therapeutic effect largely depends on the intraoperative vascular separating range,the location and size of the tumor,the scope of lymphoid infiltrates by neoplast,the intubation site for perfusion and the sequence of opening the occlusion vessel.Thus,it's necessary to set up a scientific,normative ALT procedure to improve the therapeutic effect and prognosis.
