ABSTRACT

Colorectal cancer (CRC) is the third most lethal cancer and leading cause of cancer mortality worldwide. A key driver of CRC development is colon inflammatory responses especially in patients with inflammatory bowl disease (IBD). It has been proved that Panax notoginseng saponins (PNS) have anti-inflammatory, anti-oxidant and anti-tumor effects. The chemopreventive and immunomodulatory functions of PNS on colitis-associated colorectal cancer (CAC) have not been evaluated.This present study was designed to study the potential protective effects of PNS on AOM/DSS-induced CAC mice to explore the possible mechanism of PNS against CAC. Our study showed that PNS significantly alleviated colitis severity and prevented the occurrence of CAC. Functional assays revealed that PNS relieved immunosuppression of Treg cells in the CAC microenvironment by inhibiting the expression of IDO1 mediated directly by signal transducer and activator of transcription 1 (STAT1) rather than phosphorylated STAT1. Ultimately, Rh1, one of the PNS metabolites, exhibited the best inhibitory effect on IDO1 enzyme activity. Our study showed that PNS exerted significant chemopreventive function and immunomodulatory properties on CAC. It could reduce macrophages accumulation and Treg cells differentiation to reshape the immune microenvironment of CAC. These findings provided a promising approach for CAC intervention.

ABSTRACT

Benign prostatic hyperplasia (BPH) is a common disease in elderly men, and transurethral laser prostatectomy (TULP) has been widely used in the clinic to remove bladder outlet obstruction caused by BPH. Previous animal models for wound repair after prostatectomy have many limitations, and there have been no previous reports of a mouse model of TULP. Therefore, this study aimed to establish a novel mouse model of TULP. Twelve healthy adult Kunming (KM) mice received transurethral laser vaporization prostatectomy with a 200-μm thulium laser. The mice were sacrificed, and wound specimens from the prostatic urethra and bladder neck were harvested at 1 day, 3 days, 5 days, and 7 days after surgery. Hematoxylin-eosin (HE) and immunohistochemistry were applied to confirm the establishment of the mouse TULP model. One day after the surgery, urothelium expressing uroplakin (UPK) was absent in the urethral wound site, and a large number of necrotic tissues were found in the wound site. There was no UPK-positive urothelium in the wound 3 days after surgery. At 5 days after surgery, monolayer urothelium expressing UPK was found in the wound site, indicating that the re-epithelization of the wound had been completed. On the 7th day after surgery, there were multiple layers of urothelium with UPK expression, indicating that the repair was completed. It is feasible to establish a mouse TULP model by using a microcystoscope system and a 200-μm thulium laser.

ABSTRACT

Clarifying the mechanisms of Chinese medicinal processing is pivotal to the modernization of Chinese medicine. Research on Chinese medicinal processing gives priority to the mechanisms of the processing in enhancing efficacy, reducing toxicity, and repurposing medicinals. During the past 20 years, scholars have carried out in-depth studies on the mechanisms of Chinese medicinal processing via modern system biology. They mainly focused on the changes of medicinal properties and efficacy caused by processing using techniques of modern pharmacology and molecular biology, spectrum-efficacy correlation, and biophoton emission. However, these techniques fail to reflect the holistic view of traditional Chinese medicine. With the introduction of system biology, multi-omics techno-logies(genomics, transcriptomics, proteomics, and metabolomics) have surged, which have been applied to the research on the mec-hanisms of Chinese medicinal processing. These multi-omics technologies have advantages in the research on holism. This study aims to summarize the research techniques and approaches in system biology for mechanisms of Chinese medicinal processing in the past 20 years and analyze the limitations and advantages of them. It is concluded that the multi-omics techniques of system biology can reconstruct the mechanisms of Chinese medicinal processing. This study provides a new direction for further research on the mechanisms of Chinese medicinal processing.

ABSTRACT

The research on the processing mechanism of Chinese medicine is the key and core foundation to improve processing technologies of Chinese medicine, formulate the quality standards of Chinese medicinal pieces, enhance the clinical efficacy of Chinese medicine, enrich Chinese medicine processing theories, and promote the development of Chinese medicine processing. Many researc-hers have conducted in-depth exploration on the processing mechanism of Chinese medicine in the 20 years in the 21 st century. Significant progress has been made in the transformation of chemical components during the processing, the change of active components in the body, the law of toxicity attenuation in the processing of toxic Chinese medicine, the mechanism of efficacy enhancement and toxicity attenuation of processing with auxiliary materials, and the application of new biomedical technologies. At present, the processing mechanism of multiple Chinese medicines has been preliminarily clarified, which has greatly promoted the development of Chinese me-dicine processing. The development of the processing mechanism of Chinese medicine reveals that the in vitro transformation of chemical components is combined with the in vivo absorption, transport, and metabolism, and the macroscopic biological effects of the organism are combined with the cells, molecules, targets, and pathways in the study of the processing mechanism of Chinese medicine. More attention has been paid to exploring the processing mechanism from the overall level, and a modern systematic research system on the processing mechanism of Chinese medicine has been initially formed. To further promote the scientific development of Chinese me-dicine processing, the present study proposed that the research on the processing mechanism of Chinese medicine should take Chinese medicine properties into account, focus on the influence of disease condition on the mode of action and effect strength of the drugs, comply with the characteristics of clinical compound compatibility of Chinese medicine, use the holistic view research strategies of systems bio-logy, and deeply explore the processing mechanism of Chinese medicine from traditional Chinese medicine theories and the characteristics of clinical medication of Chinese medicine.

ABSTRACT

Chinese medicine undergoes complex chemical changes during processing and identifying these changes is the key to the processing mechanism. In the past 20 years of the 21 st century, research on the chemical changes in Chinese medicine after processing has focused the changes in the biopharmaceutical process in addition to the variation during processing. With the surging of information technologies, various identification technologies(instrumental analysis techniques, molecular biological techniques, data mining techniques, and biotransformation techniques) have developed rapidly and been widely applied to the research on processing mechanism. Thus, based on the chemical changes in the processing and biopharmaceutical process, the author suggested a research tactic of multimodal identification as the core by reorganizing key technologies for chemical identification from studies of the processing mechanism of Chinese me-dicine, aiming at establishing an interdisciplinary multi-dimensional research model for the processing mechanism of Chinese medicine.

ABSTRACT

Tsaoko Fructus is a type of food with the homology of medicine and food,and has a long history of cultivation and application in China. With the deepening of the development and utilization of Tsaoko Fructus,its economic value has appeared obviously,and relevant industries have great potential,with an important role in poverty alleviation in mountainous areas. However,the plants source of Tsaoko Fructus are confused in the process of actual production and resource utilization,and there is a lack of systematic report about the origin of varieties and medicinal history. The paper focused on a textual research for its names,plant sources,changes of the genuine producing areas and traditional efficacy through consulting the herbal works and the analysis of modern literature. The results showed that the medicine of Tsaoko Fructus was first recorded in ancient literatures of the Song dynasty,and there were many aliases and synonyms of the herb, with a great difference between ancient and modern times. In modern records,the medicinal alias names such as Hongcaoguo,Tucaoguo,Caoguoren are similar with the Chinese name of Caoguo,but they are not the same kind of plant and shall be distinguished. In the Ming dynasty,variety and source of the herb was complicated,and it was often recorded as the same class of medicinal materials with Amomi Fructus Rotundus and Alpiniae Katsumadai Semen,until it was listed as a class of medicinal material and distinguished from confounding medicines in the Qing Dynasty. The prescriptions containing Tsaoko Fructus include Caoguoyin,Caoguosan,Caoguowan,Caoguoshushui. Tsaoko Fructus could be used as medicine with peel or only kernel according to different diseases,and mainly processed with water or wine. In addition,there are other processing methods,such as frying,salt-processing, ginger- processing,simmering flour. Ancient literatures have basically the same records on properties,efficacies and indications of Tsaoko Fructus,considering it was warm in nature with the effect in relieving vomiting,eliminating food,intercepting malaria,expelling phlegm. This study provided a theoretical basis for its origin,quality control and resource development and utilization.

ABSTRACT

Objective:To investigate the effect of Xiaoyaosan on depressive behavioral phenotype in mice with vascular dementia (VaD) mice and its possible mechanism. Method:Sixty three-month-old male C57/BL6 mice were divided into the normal control group, model group, positive control group, as well as low-, medium-, and high-dose Xiaoyaosan groups. Mice in all groups except for the normal control group underwent bilateral carotid artery stenosis. Two weeks later, they were subjected to chronic restraint stress, 6 h per day, for inducing VaD complicated with depression. Mice in the low-, medium-, and high-dose Xiaoyaosan groups were treatment with intragastric administration of Xiaoyaosan decoction (5, 10, 20 g·kg<sup>-1</sup>), the ones in the positive control group with fluoxetine (10 mg·kg<sup>-1</sup>), and those in the normal control group and model group with an equal volume of normal saline for four weeks, during which the restraint stress was maintained. The depressive behavioral phenotype of mice was observed in sugar water preference test and tail suspension test. The fluorescence expression of myelin basic protein (MBP) in ventral hippocampus (vHIP) was detected by fluorescence immunoassay. The ultrastructure of myelin sheath in vHIP was observed by transmission electron microscopy. The protein expression levels of MBP, myelin oligodendrocyte glycoprotein (MOG), myelin-associated glycoprotein (MAG), triggering receptor expressed on myeloid cells-2 (TREM2), inducible nitric oxide synthase (iNOS), arginase 1 (Arg1), interleukin-I<italic>β</italic> (IL-1<italic>β</italic>), tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), interleukin-4 (IL-4), and interleukin-10 (IL-10) were assayed by Western blot. Result:As revealed by behavioral test, compared with the normal control group, the model group exhibited prolonged immobility time and decreased percentage of sugar water preference (<italic>P</italic><0.01). Compared with the model group, Xiaoyaosan significantly shortened the immobility time of mice (<italic>P</italic><0.05) and increased the percentage of sugar water preference (<italic>P</italic><0.01). Western blot results showed that the protein expression levels of MBP, MOG, and MAG in vHIP of the model group were remarkably decreased as compared with those of the normal control group (<italic>P</italic><0.01). The protein expression levels of MBP, MOG, and MAG in vHIP of the low-dose Xiaoyaosan group were increased in contrast to those in the model group (<italic>P</italic><0.05, <italic>P</italic><0.01), while the protein expression of iNOS was decreased (<italic>P</italic><0.01). The protein expression levels of MBP, MOG, MAG, TREM2, Arg1, IL-4, and IL-10 in the medium- and high-dose Xiaoyaosan groups were up-regulated (<italic>P</italic><0.05, <italic>P</italic><0.01), whereas those of iNOS, IL-1<italic>β</italic>, and TNF-<italic>α</italic> were down-regulated (<italic>P</italic><0.01). The immunofluorescence findings demonstrated that the mean fluorescence intensity of MBP in the model group declined in comparison with that in the normal control group (<italic>P</italic><0.01), while the mean fluorescence intensities of MBP in the low-, medium-, and high-dose Xiaoyaosan groups were enhanced to different degrees (<italic>P</italic><0.01). It was observed under the transmission electron microscope that the myelin structure of the model group was loosened and the dense layer was separated and irregularly arranged. Xiaoyaosan improved the structural integrity of myelin sheath and the looseness of lamellar structure. Conclusion:Xiaoyaosan ameliorates the depressive behavioral phenotype of VaD mice, which may be related to the up-regulation of TREM2, the induction of M2 polarization of microglia cells, the enhancement of their anti-inflammatory and phagocytic abilities, and the promotion of damaged myelin sheath regeneration.

ABSTRACT

Objective:The purpose of this article was to observe the effect of modified Shengjiangsan on podocyte apoptosis in membranous nephropathy (MN) rats, to explore the molecular mechanism of its treatment of MN and to provide experimental basis for its clinical application. Method:The MN rat model was established by injection of cationic bovine serum albumin into the tail vein of rats. The successfully modeled rats were then randomly divided into model group (equal volume of normal saline), modified Shengjiangsan group (27.3 g·kg<sup>-1</sup>) and benazepril group (10 mg·kg<sup>-1</sup>), with corresponding drug dosage once a day for 4 weeks of continuous intervention. After drug administration, the 24-hour urine protein (UTP) was detected. Real time fluorescent quantitative polymerase chain reaction (Real-time PCR) and immunohistochemical (IHC) methods were used to detect Podocalyxin, Nephrin, Podocin, Synaptopodin mRNA and protein expression levels in rat kidney tissue. terninal-deoxynucleoitidyl transferase medsated nick and labeling (TUNEL) method was used to detect cell apoptosis rate in rat kidney tissue, and Western blot was used to detect Notch1, Hes1, B lymphoblastoma-2 (Bcl-2) associated X protein (Bax), and Bcl-2 protein expression levels in rat kidney tissue. Result:Compared with the normal group, UTP in the model group increased significantly, renal tissue cell apoptosis increased significantly, podocyte marker proteins podocalyxin, Nephrin, Podocin, Synaptopodin mRNA and protein expression levels decreased significantly, and Notch1, Hes1, Bax protein expression increased significantly, and Bcl-2 protein expression was significantly reduced(<italic>P</italic><0.05). Compared with the model group, UTP levels in MN rats were significantly reduced in modified Shengjiangsan and benazepril groups, with reduced rate of renal cell apoptosis, increased mRNA and protein expression levels of podocalyxin, Nephrin, Podocin, and Synaptopodin in renal tissue, decreased Notch1, Hes1, Bax protein expression, and increased Bcl-2 protein expression(<italic>P</italic><0.05). Conclusion:Modified Shengjiangsan can inhibit the Notch signaling pathway, reduce the apoptosis of rat kidney tissue podocytes, and reduce the kidney injury of MN rats.

ABSTRACT

At present, the modernization of Chinese medicine preparations (CMPs) is still a challenging task. The 3 typical Chinese medicine materials (CMMs) used for preparing CMPs are the powders, extracts, and components of Chinese medicine and their properties of CMMs are important for designing CMPs. Basing on our long term research, we have established a property system for CMMs according to the state of CMMs under an exactly condition and according to the interaction characteristics between substances. The property system could be divided into 5 categories: material composition, spatial structure, body property, surface property, physicochemical properties, and they could also be divided into 18 subcategories. Furthermore, we also established the corresponding index and characterization system, where the 61 indexes and characterization techniques were systematically summarized. At last, we hope that the article will promote the modernization of CMPs.

ABSTRACT

Purpose@#The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. @*Materials and Methods@#A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. @*Results@#Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. @*Conclusion@#LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

ABSTRACT

OBJECTIVE@#To observe the effect of hypnosis on pain and fear in the healthy acupuncture subjects.@*METHODS@#A total of 52 healthy subjects were randomized into an observation group and a control group, 26 cases in each one. In the observation group, the subjects received the first-time acupuncture under hypnosis. After wakened up and 30 min later, the subjects received the second-time acupuncture under clear consciousness condition. In the control group, the subjects received the first-time acupuncture under clear consciousness condition, 30 min later, received the second-time acupuncture under hypnosis. Likert scale was adopted to investigate the relaxation, pain sensation and the willingness in the subjects at the normal condition before acupuncture, after the first-time and the second-time acupuncture of the two groups separately. Using Boeran electronic blood pressure monitor, the pulse and blood pressure were measured in the subjects at the normal condition and after the first-time acupuncture of the two groups.@*RESULTS@#Compared with the normal condition, the relaxation degree was increased, the pain sensation decreased and the willingness enhanced after acupuncture either after hypnosis or after wakened-up in the observation group (0.05). In the control group, compared with the normal condition, after the first-time acupuncture (acupuncture in clear consciousness), the relaxation degree was decreased, pain was alleviated and the willingness was increased when acupuncture was exerted once again (0.05); compared with the first-time acupuncture, the relaxation degree was increased, pain alleviated and willingness enhanced after the second-time acupuncture (acupuncture after hypnosis) (0.05). In the control group, compared with the normal condition, the pulse was faster, both the diastolic pressure and systolic pressure were increased after the first-time acupuncture (<0.05, <0.01). In the observation group, compared with the normal condition, the pulse was getting slow and blood pressure was reduced after the first-time (acupuncture under hypnosis, <0.01). Compared with the first-time acupuncture in the control group, pulse was getting slow and blood pressure was reduced in the observation group after acupuncture under hypnosis (<0.001).@*CONCLUSION@#During acupuncture, with hypnosis combined, the fear alleviates, pain reduces and the willingness of acupuncture increases in the subjects.

ABSTRACT

Objective: To explore the factors affecting the nasal entry of the pharmaceutical preparations into the brain based on the established model of the "nose-brain" pathway in vitro. Methods: Calu-3 cells and OECs cells were co-cultured to construct a "nasal-brain" pathway cell model group. Taking fluorescein isothiocyanate dextran (FD) and fluorescent silver nanoparticles (AgNPs) as model drugs, the effects of drug molecular weight (Mw) factors and preparation particle size factors on the drug transnasal transport into the brain were explored. Results: The apparent permeability coefficient (Papp) of transcellular monolayer transport of FD decreased with the increase of molecular weight. The uptake of fluorescein isothiocyanate dextran with different molecular weights by OECs tended to be saturated after 90 min. As the molecular weight of FD increased, the uptake of OECs decreased significantly during the same uptake time. The apparent permeability coefficient of fluorescent AgNPs with different particle sizes in the "nose-brain" multi-channel cell model group of calu-3 monolayer decreased with the increase of the particle size of the nanoparticles. When the particle size was less than 40 nm, its transport characteristics in Calu-3 were shown as medium absorption (1 × 10-6 < Papp < 10 × 10-6), and when the particle size of nanoparticles was more than 60 nm, its transport characteristics were shown as difficult to absorb (Papp < 1 × 10-6). The uptake of OECs of fluorescent AgNPs with different particle sizes tended to be saturated at 60 min, and with the increase of the particle size of fluorescent AgNPs, the uptake of OECs at the same uptake time showed a significant decline. Conclusions The Mw of the drug and the particle size of the nano-formulation have an important influence on the nasal transport of the drug into the brain. Drugs with a molecular weight of < 4 000 and nano particles with a particle size of less than 40 nm have better transport and uptake characteristics.

ABSTRACT

In the past decade, in addition to using traditional naked-eye morphological analysis, two-dimensional measurement and data comparison, more and more scholars placed great emphasis on the application of new technologies available and supported the study of ancient human remains from a multi-disciplinary perspective. Through outlining recent advances in the application of new techniques on research of ancient human remains, this paper briefly summarized the characteristics of present research and gave an outlook on future research of ancient human remains in China.
