ABSTRACT

Due to its complex pathogenesis and lack of effective therapeutic methods, Alzheimer's disease (AD) has become a severe public health problem worldwide. Recent studies have discovered the function of central nervous system lymphatic drainage, which provides a new strategy for the treatment of AD. Chinese herbal medicine (CHM) has been considered as a cure for AD for hundreds of years in China, and its effect on scavenging β-amyloid protein in the brain of AD patients has been confirmed. In this review, the mechanism of central nervous system lymphatic drainage and the regulatory functions of CHM on correlation factors were briefly summarized. The advances in our understanding regarding the treatment of AD via regulating the central lymphatic system with CHM will promote the clinical application of CHM in AD patients and the discovery of new therapeutic drugs.

ABSTRACT

The immune checkpoint blockade therapy has profoundly revolutionized the field of cancer immunotherapy. However, despite great promise for a variety of cancers, the efficacy of immune checkpoint inhibitors is still low in colorectal cancer (CRC). This is mainly due to the immunosuppressive feature of the tumor microenvironment (TME). Emerging evidence reveals that certain chemotherapeutic drugs induce immunogenic cell death (ICD), demonstrating great potential for remodeling the immunosuppressive TME. In this study, the potential of ginsenoside Rg3 (Rg3) as an ICD inducer against CRC cells was confirmed using in vitro and in vivo experimental approaches. The ICD efficacy of Rg3 could be significantly enhanced by quercetin (QTN) that elicited reactive oxygen species (ROS). To ameliorate in vivo delivery barriers associated with chemotherapeutic drugs, a folate (FA)-targeted polyethylene glycol (PEG)-modified amphiphilic cyclodextrin nanoparticle (NP) was developed for co-encapsulation of Rg3 and QTN. The resultant nanoformulation (CD-PEG-FA.Rg3.QTN) significantly prolonged blood circulation and enhanced tumor targeting in an orthotopic CRC mouse model, resulting in the conversion of immunosuppressive TME. Furthermore, the CD-PEG-FA.Rg3.QTN achieved significantly longer survival of animals in combination with Anti-PD-L1. The study provides a promising strategy for the treatment of CRC.

ABSTRACT

Simiao Wan (SMW) is a traditional Chinese formula, including Atractylodis Rhizoma, Achyranthis Bidentatae Radix, Phellodendri Chinensis Cortex and Coicis Semen at the ratio of 1:1:2:2. It can be used to the treatment of diabetes. However, its bioactive compounds and underlying mechanism are unclear. This study aimed to screen the antilipolytic fraction from SMW and investigate its therapeutic mechanisms on hepatic insulin resistance. Different fractions of SMW were prepared by membrane separation combined with macroporous resin and their antilipolytic activities were screened in fasted mice. The effects of 60% ethanol elution (ESMW) on lipolysis were investigated in 3T3-L1 adipocytes stimulated by palmitic acid (PA) and high fat diet (HFD)-fed mice. In our study, ESMW is the bioactive fraction responsible for the antilipolytic activity of SMW and 13 compounds were characterized from ESMW by UHPLC-QTOF-MS/MS. ESMW suppressed protein kinase A (PKA)-hormone-sensitive lipase (HSL) related lipolysis and increased AMP-activated protein kinase (AMPK) phosphorylation in PA challenged 3T3-L1 adipocytes. AMPKα knockdown abolished the inhibitory effects of ESMW on IL-6 and HSL pSer-660, revealing that the antilipolytic and anti-inflammatory activities of ESMW are AMPK dependent. Furthermore, ESMW ameliorated insulin resistance and suppressed lipolysis in HFD-fed mice. It inhibited diacylglycerol accumulation in the liver and inhibited hepatic gluconeogenesis. Conditional medium collected from ESMW-treated 3T3-L1 cells ameliorated insulin action on hepatic gluconeogenesis in liver cells, demonstrating the antilipolytic activity contributed to ESMW beneficial effects on hepatic glucose production. In conclusion, ESMW, as the antilipolytic fraction of SMW, inhibited PKA-HSL related lipolysis by activating AMPK, thus inhibiting diacylglycerol (DAG) accumulation in the liver and thereby improving insulin resistance and hepatic gluconeogenesis.

ABSTRACT

This study was aimed to explore the effect of Zingiberis Rhizoma extract on rats with antibiotic-associated diarrhea(AAD), and reveal the modulation of gut microbiota during alleviation of AAD. AAD rat model was successfully established by exposing rats to appropriate antibiotic mixed solution. Peficon(70 mg·kg~(-1)·d~(-1)) was used as positive control, then rats were treated with 200 mg·kg~(-1)·d~(-1) and 400 mg·kg~(-1)·d~(-1) of Zingiberis Rhizoma extract for low and high dosage groups of Zingiberis Rhizoma extract, respectively. The weight changes of the rats were observed, and the degree of diarrhea were evaluated by fecal score, 120 min fecal weight and fecal water content. Colon tissues for histopathological examination were stained with hematoxylin and eosin(HE), and 16 S rRNA sequencing analysis of gut microbiota was performed. The results showed that compared with the model group, the degree of diarrhea, indicated by fecal water content, fecal score, and 120 min fecal weight of positive control group, Zingiberis Rhizoma low-dose group and Zingiberis Rhizoma high-dose group were significantly ameliorated. And the treatment of Zingiberis Rhizoma could significantly improve the pathological condition of colon tissue in AAD rats, especially the high dose of Zingiberis Rhizoma. In addition, 16 S rRNA sequencing analysis of gut microbiota showed that the diversity and abundance of gut microbiota were significantly improved and the reco-very of gut microbiota was accelerated after given high-dose of Zingiberis Rhizoma, while no significant changes of alterations were observed after given Pefikon. Of note, compared with the pefikon group, the abundance and diversity of gut microbiota in Zingi-beris Rhizoma high-dose group were significantly elevated. At the phylum level, the abundance of Firmicutes in AAD rats increased and the abundance of Proteobacteria was decreased after the Zingiberis Rhizoma intervention. At the genus level, the abundance of Bacillus spp., Lachnoclostridium and Escherichia coli-Shigella were decreased, and the abundance of Lactobacillus spp., Trichophyton spp., and Trichophyton spp., etc., were increased. While compared with the AAD model group, there was no significant difference of gut microbiota after given Peficon. The results showed that Zingiberis Rhizoma exerted beneficial health effects against AAD, and positively affected the microbial environment in the gut of rats with AAD.

ABSTRACT

Perineuronal nets (PNNs) is a complex network composed of highly condensed extracellular matrix molecules surrounding neurons. It plays an important role in maintaining the performance of neurons and protecting them from harmful substances. However, after spinal cord injury, PNNs forms a physical barrier that surrounds the neuron and limits neuroplasticity, impedes axonal regeneration and myelin formation, and promotes local neuroinflammatory uptake. This paper mainly describes the composition and function of PNNs of neurons and its regulatory effects on axonal regeneration, myelin formation and neuroinflammation after spinal cord injury.

ABSTRACT

Identification of the target proteins of small molecule drugs is crucial for understanding the mechanisms of drug actions and its side effects. Conventional methods require chemical modification, which might alter the activities of the drugs. Various label-free techniques have been developed to identify drug target proteins without chemical modifications. This includes drug affinity responsive target stability (DARTS), stability of proteins from rates of oxidation (SPROX), cellular thermal shift assay (CETSA), thermal proteome profiling (TPP) and many others. Here we review the principles and applications of these label-free techniques, their advantages and limitations, as well as the most recent advances.

ABSTRACT

@#Objective    To investigate the safety and feasibility of laryngeal mask general anesthesia as a replacement of tracheal intubation general anesthesia in the "three-port" thoracoscopic thymectomy via subxiphoid and subcostal arch for thymoma patients without myasthenia. Methods    From January 2018 to June 2019, clinical data of patients with thymoma who underwent the novel "three-port" operation in our institution were analyzed retrospectively. The patients were divided into two groups according to the anesthesia methods, including a tracheal intubation general anesthesia group and a laryngeal mask general anesthesia group. There were 70 patients in the tracheal intubation general anesthesia group, including 42 males and 28 females, with an average age of 45.83±15.89 years. There were 39 patients in the laryngeal mask general anesthesia group, including 26 males and 13 females, with an average age of 43.31±15.64 years. The clinical data of the two groups were compared. Results    The baseline characteristics of the patients in the two groups were well balanced (P>0.05). No massive bleeding, conversion to thoracotomy, postoperative myasthenia or death occurred in those patients. No patient with laryngeal mask anesthesia had a conversion to tracheal intubation anesthesia during the operation. There was no significant difference in the operation time, intraoperative bleeding, intraoperative maximum partial pressure of CO2, lowest partial pressure of oxygen and anesthesia effect score between the two groups (P>0.05). There was also no statistical difference in postoperative aspiration, gastrointestinal discomfort, length of hospital stay, pain score and patient satisfaction degree between the two groups (P>0.05). However, the anesthesia time before operation and the time of awake after anesthesia in the laryngeal mask anesthesia group were significantly shorter than those in the tracheal intubation general anesthesia group (P<0.05), and the incidence of transient arrhythmia, laryngeal discomfort and hoarseness in the laryngeal mask general anesthesia group was significantly lower than that in the tracheal intubation general anesthesia group (P<0.05). Conclusion    The "three-port" thoracoscopic thymectomy via subxiphoid and subcostal arch under laryngeal mask general anesthesia is safe and feasible in the treatment of thymoma without myasthenia, and can be recommended routinely.

ABSTRACT

Xianling Gubao is a common and effective medicine in the treatment of orthopedic diseases. In recent years, it has been reported to be associated with liver injury. However, through the analysis of the adverse drug reaction reports and key hospital cases, we found that there is considerable incomplete information in the reports of Xianling Gubao-related liver injury cases retrieved from the literature. Thus, it is difficult to accurately judge causality between the drug and liver injury. Six cases of liver injury related to Xianling Gubao were identified in key hospitals, two of which achieved the clinical diagnosis according to the assessment of the integrated evidence chain method. We further analyzed the public health data of all residents in Yinzhou. The gross incidence rate of Xianling Gubao-related liver injury was 0.034%, which corresponds to a level of rare incidence. This revealed that Xianling Gubao-related liver injury has significant divergence in individuals and an idiosyncratic nature. The gross incidence of liver injury related to Xianling Gubao was lower than that of other medicines for the treatment of orthopedic diseases. Based on the idiosyncratic drug-induced liver injury model mediated by immune stress, it was found that Epimedii Folium and Psoraleae Fructus were the major components that lead to liver injury, and the liver injury caused by a full prescription was less serious than that encountered with only Epimedii Folium and Psoraleae Fructus. This suggests that the other 4 herbs (Dipsaci Radix, Anemarrhenae Rhizoma, Rehmanniae Radix,Salviae Miltiorrhizae Radix et Rhizoma) can prevent/alleviate the liver injury. Through disassembled prescription analysis, we found that the attenuation efficacy of Salviae Miltiorrhizae Radix et Rhizoma was the most significant. In conclusion, Xianling Gubao may cause idiosyncratic liver injury in a tiny minority of susceptible individuals, but the incidence risk is lower than that of other commonly used drugs for orthopedic disease. Xianling Gubao should be discreetly applied to patients with immune stress. The major components that induced liver injury in Xianling Gubao were Epimedii Folium and Psoraleae Fructus, and Salviae Miltiorrhizae Radix et Rhizoma appears to attenuate this toxicity. This study provides a reference for the rational clinical medication with Xianling Gubao.

ABSTRACT

Objective:To study the effect mechanism of Guilu Erxian gum on Alzheimer's disease (AD) from the perspective of regulating perivascular space (PVS),and to explore the scientific connotation of "essence generating marrow". Method:The 80 patients with AD diagnosed by western medicine and kidney deficiency and marrow empty syndrome diagnosed by traditional Chinese medicine were randomly divided into two groups,with 40 cases in each group. Both groups of patients were orally administered with cholinesterase inhibitor Alison,one tablet (5 mg) each time before sleep at night. On this basis,the control group additionally received placebo,while the treatment group was additionally treated with Guilu Erxian gum for 60 days. The Mini-Mental State Examination scale (MMSE), Wechsler Memory Scale and Activity of Daily Living Scale (ADL) were used before treatment (0 d),as well as 31 d and 61 d after treatment. The number and diameter of PVS in midbrain,basal ganglia,deep insular white matter and semiovale center were counted and their diameters were measured with use of nuclear magnetic resonance imaging (MRI) for head. In addition,the curative effect was evaluated according to MMSE scores on 61 d. Result:There was no significant difference between the two groups 31 d. On 61 d,MMSE and WMS scores increased,while ADL scores decreased as compared with the conditions on 0 d(<italic>P</italic><0.01),and there were significant differences in the three indexes and clinical effective rate between two groups (<italic>P</italic><0.05,<italic>P</italic><0.01) . In addition,there was no significant difference in the number of PVS as compared with the number before treatment and in the comparison between the two groups after treatment,but there was a significant difference in the diameter of PVS(<italic>P</italic><0.01). Conclusion:Guilu Erxian gum is effective in the treatment of AD,and it can improve the PVS diameter in patients,which may be related to the mechanism of "essence generating marrow ".

ABSTRACT

Objective:To investigate the anti-inflammatory effects of water extract of the<italic> Iris halophila</italic> root on lipopolysaccharide(LPS) stimulated RAW264.7 cells and analyze its chemical constituents. Method:The supernatant of YWG prepared by water extraction and alcohol precipitation was separated by AB-8 macroporous adsorption resin column chromatography to obtain ethanol eluates with different concentrations (YWG,YWG-0%,YWG-20%,YWG-40%,and YWG-60%). Cell counting kit-8(CCK-8) assay was used to determine the effects of YWG-0%,YWG-20%,YWG-40%,and YWG-60% on the viability of RAW264.7 cells. Griess assay was employed to detect the nitric oxide (NO) level in LPS-stimulated RAW264.7 cells. The release of tumor necrosis factor(TNF)-<italic>α</italic>,interleukin(IL)-6,IL-10,and IL-1<italic>β</italic> was detected by enzyme-linked immunosorbent assay(ELISA). YWG and the elution site with the most robust anti-inflammatory activity were identified and compared by ultra-high performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UHPLC-Q-TOF-MS/MS). Result:Ethanol eluates with different concentrations inhibited the release of NO,TNF-α,IL-1<italic>β</italic>, and IL-6 in the supernatant of LPS induced RAW264.7 cells (<italic>P<</italic>0.05),and promoted the release of IL-10 (<italic>P<</italic>0.05). YWG-60% displayed a highly significant effect (<italic>P</italic><0.01). A total of 127 constituents were detected from the comparison of YWG and YWG-60% by UHPLC-Q-TOF-MS/MS in the positive and negative ion modes,including 61 flavonoids. YWG-60% contained 25 flavonoids with elevated content as compared with YWG. Conclusion:YWG-60% showed potent anti-inflammatory effect,and the effective anti-inflammatory constituents were presumedly flavonoids. The findings of this study are expected to provide a scientific theoretical basis for the basic research on the medicinal effect of the water extract of YWG.

ABSTRACT

The elements of ethical review related to clinical research of acupuncture and moxibustion is discussed to provide ideas for various institutions to carry out relevant ethical review. It is believed that the ethical review of clinical research of acupuncture and moxibustion needs to focus on the specificity of acupuncture and moxibustion. Starting from the basic theory of traditional Chinese medicine, the theory of meridians and acupoints and the theory of syndrome differentiation along meridians, the key contents of ethical review such as intervention methods, grouping design and placebo control should be considered, so as to standardize the clinical research of acupuncture and moxibustion and protect the health and rights and interests of participants.

ABSTRACT

Objective:To find the age-related indicators of human immune function in the blood, to explore the possibility to standardize the evaluation criterion of immune function in Chinese population.Methods:The peripheral blood samples from 478 healthy individuals with complete medical data collected at the Beijing Hospital from January 2019 to December 2019, were chosen and analyzed.The volunteers were divided into young(<40 years old)and elderly(≥70 years old)groups.The differences in RNA, cytokines and immune cell function(the proliferation of T cell as well as the ability of T cells and natural killer cells to lyse target cells)were compared between the young group versus the elderly group.Results:Real-time quantitative fluorescence RT-PCR detection method was used for detecting the following tumor immune-related genes in the peripheral blood of healthy people in young versus old groups: programmed death 1( PD1)gene, complement C3 gene( C3), complement C4 gene( C4), high sensitivity C-reactive protein gene( HsCRP), tumor necrosis factor alpha gene( TNFA), interferon gamma gene( INF- γ), interleukin-6 gene( IL-6), interleukin-8 gene( IL-8), cytotoxic T lymphocyte-associated antigen-4 gene( CTLA-4), nuclear transcription factor-κB gene( NF- κB), long intergenic noncoding RNA-erythroid pro-survival gene( lincRNA- EPS), long non-coding RNA-myeloid RNA regulator of Bim-induced death gene( lncRNA- Morrbid), lincRNA-cyclooxygenase 2 gene( lincRNA- Cox2), Lnc-Dendritic cells( Lnc- DC), and circRNA-7 gene( ciRS-7). The mRNA level of C4 was significantly lower in elderly people than in young controls[young group(1.01±0.18) vs.old group(0.64±0.13), P=0.047], while others showing a non-statistically significant difference( P>0.05). The protein levels of programmed death 1(PD1), complement C3(C3), complement C4(C4), high sensitivity C-reactive protein(HsCRP), tumor necrosis factor alpha(TNF-α), interferon gamma(INF-γ), interleukin-6(IL-6), interleukin-8(IL-8), cytotoxic T lymphocyte-associated antigen-4(CTLA-4)and nuclear transcription factor-κB(NF-κB)in plasma were detected by enzyme-linked immunosorbent assay(ELISA). The following protein levels were significantly higher in the elderly group than in the young group: IL-6 protein[young group(249.30±100.02)ng/L vs.old group(283.00±94.98)ng/L, P=0.021], HsCRP protein[young group(2543.00±1111.89)ng/L vs.old group(3056.00±1056.61)ng/L, P=0.002], INF-γ protein[young group(362.40±383.67)ng/L vs.old group(500.40±502.27)ng/L, P=0.047]and TNF-α protein[young group(20.74±29.47)ng/L vs.old group(33.09±48.91)ng/L, P=0.042]. While the level of C4 was significantly lower in the elderly group than in the young group[young group(449.50±51.17)ng/L vs.old group(407.10±59.78)ng/L, P<0.0001]. T-cell proliferation, quantified by flow cytometry-based fluorescent dye dilution, showed that the CD3 + T cells of elder people had proliferated through 4 generations, while the CD3 + T cells of young people had proliferated through 5 generations.As shown in the NK killing assays, the secretion of LDH in the target A549 tumor cells decreased significantly after treated with NK cells belonging to elder individuals.The result demonstrated that individuals over 70 years old have significantly lower levels of the killing activity of NK cells( P<0.05). However, there was not statistically significant in T lymphocyte killing activity between different ages( P>0.05). Conclusions:IL-6, HsCRP, INF-γ and TNF-α levels are increased with aging, while the level of C4 significantly is decreased.The proliferation ability of T cells and the ability of NK cells to kill tumor cells are weakened.

ABSTRACT

OBJECTIVE@#To develop the clinical prediction model of therapeutic effect in treatment with acupuncture and moxibustion for the patients with stroke at recovery stage under different conditions so as to provide a tool for predicting the therapeutic effect of acupuncture and moxibustion.@*METHODS@#A total of 1410 patients with stroke at recovery stage were collected from the Third Affiliated Hospital of Zhejiang Chinese Medical University from 2012 to 2019. The relevant data were extracted, i.e. sex, age, time of onset, neurological functional deficit score (NFDS) and acupuncture and moxibustion therapy. The difference of NFDS before and after treatment was adopted to evaluate the therapeutic effect in the patients. Using SPSS26.0 software and CART decision tree analysis, the clinical prediction model was developed.@*RESULTS@#The key variables in the prediction model of therapeutic effect in the patients with stroke at recovery stage under different conditions included age, time of onset, hypertension, cardiac disease, diabetes, TCM diagnosis, hemoglobin (HB), serum homocysteine (HCY) and acupuncture and moxibustion therapy. There were 12 main rules generated by the decision tree model, including 8 rules for predicting the improvements of therapeutic effect and 4 rules for predicting the absence of improvements (i.e. no change and deterioration). The accuracy rates of the model training set and test set were 80.0% and 72.8% respectively, the area under curve (AUC) of ROC was 0.797 and the model identification and classification results were satisfactory.@*CONCLUSION@#The clinical prediction model developed by CART decision tree analysis is high in accuracy for the prediction of the therapeutic effect in the patients with stroke at recovery stage under different conditions. Based on the therapeutic effect predicted in the hospital visit, the physicians may adopt the corresponding regimens of acupuncture and moxibustion therapy in patients.

ABSTRACT

Objective: To observe the clinical efficacy of ginger-partitioned moxibustion plus pediatric massage (tuina) in treating infantile diarrhea due to spleen deficiency. Methods: Ninety infants were randomly divided into a massage plus moxibustion group, a massage group and a drug group by the random number table method, with 30 cases in each group. The intervention was conducted for two consecutive courses. The infants in the massage plus moxibustion group were treated with pediatric massage and ginger-partitioned moxibustion at Shenque (CV 8). The infants in the massage group were treated with pediatric massage alone, while those in the drug group were treated with smecta. The primary and secondary symptom scales were assessed before and after treatment and at the follow-ups, and the total effective rate was evaluated after treatment. Results: The total effective rate in the massage plus moxibustion group was significantly different from that in the massage group and drug group (both P<0.05). After treatment, the scores of primary and secondary symptoms decreased in all three groups, with statistically significant intra-group differences (all P<0.05); the scores of primary symptoms were significantly different between the massage plus moxibustion group and the drug group (P<0.05); the scores of secondary symptoms in the massage plus moxibustion group and the massage group were significantly different from that in the drug group (both P<0.05). The differences in the time to recover normal bowel movement frequency among the three groups were not statistically significant (P>0.05). Conclusion: Ginger-partitioned moxibustion plus pediatric massage compared with pediatric massage or smecta monotherapy shows superior clinical efficacy in treating infantile diarrhea due to spleen deficiency, and has the advantages of appetite improvement, physique strengthening and short course.

The clinical and laboratory data of a patient with chronic refractory immune thrombocytopenia (ITP) who had a significant increase in the proportion of inhibitory T cells in the hematological oncology center of Beijing Children′s Hospital Affiliated to Capital Medical University in February 2018 and regularly followed up in the outpatient department received a retrospective analysis.This 8-year-old patient′s clinical features were 6 years of skin and mucous membrane bleeding spots and petechiae recurring, with occasionally nasal epistaxis.Physical examination: cardiopulmonary abdomen and nervous system examinations are normal, and no superficial lymphadenopathy is touched.Blood routine indicated that the platelets were 2.00×10 9/L, and white blood cell count and hemoglobin level were normal.Bone marrow suggested that hyperplasia was significantly active, with more than 300 megakaryocytes.The patient was diagnosed with ITP, and he was treated with first-line treatment with gamma globulin and oral Corticosteroids.The first-line treatment with high-dose Dexamethasone therapy was repeated, and the second-line treatment was low-dose Rituximab combined with high-dose Dexamethasone.Evaluations had been conducted with every relapsed course, and Cyclosporine was administered orally on the basis of the highly suppressive T cells.After half a month, the child achieved partial remission and continued for 3 months, and then reached a complete remission of 6 months (till this paper). It is suggested that, with ITP as an immunological disease with high heterogeneity, the immune abnormality index is expected to become a breakthrough in the development of precise treatment.
