ABSTRACT

Objective@#To compare the reproducibility and performance of quantitative metrics between ZOOMit and conventional intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) in the diagnosis of early- and mid-stage Sjögren’s syndrome (SS). @*Materials and Methods@#Twenty-two patients (mean age ± standard deviation, 52.0 ± 10.8 years; male:female, 2:20) with early- or mid-stage SS and 20 healthy controls (46.9 ± 14.6 years; male:female, 7:13) were prospectively enrolled in our study.ZOOMit IVIM and conventional IVIM MRI were performed simultaneously in all individuals using a 3T scanner. Quantitative IVIM parameters - including tissue diffusivity (D), pseudodiffusion coefficient (D*), and perfusion fraction (f) - inter- and intra-observer reproducibility in measuring these parameters, and their ability to distinguish patients with SS from healthy individuals were assessed and compared between ZOOMit IVIM and conventional IVIM methods, appropriately. MR gland nodular grade (MRG) was also examined. @*Results@#Inter- and intra-observer reproducibility was better with ZOOMit imaging than with conventional IVIM imaging (ZOOMit vs. conventional, intraclass correlation coefficient of 0.897–0.941 vs. 0.667–0.782 for inter-observer reproducibility and 0.891–0.968 vs. 0.814–0.853 for intra-observer reproducibility). Significant differences in ZOOMit f, ZOOMit D*, conventional D*, and MRG between patients with SS and healthy individuals (all p < 0.05) were observed. ZOOMit D* outperformed conventional D* in diagnosing early- and mid-stage SS (area under receiver operating curve, 0.867 and 0.658, respectively; p = 0.002). The combination of ZOOMit D*, MRG, and ZOOMit f as a new diagnostic index for SS, increased diagnostic area under the curve to 0.961, which was higher than that of any single parameter (all p < 0.01). @*Conclusion@#Considering its better reproducibility and performance, ZOOMit IVIM may be preferred over conventional IVIM MRI, and may subsequently improve the ability to diagnose early- and mid-stage SS.

ABSTRACT

OBJECTIVE@#To observe the changes of symptoms, Chinese medicine (CM) syndrome, and lung inflammation absorption during convalescence in patients with coronavirus disease 2019 (COVID-19) who had not totally recovered after hospital discharge and whether CM could promote the improvement process.@*METHODS@#This study was designed as a prospective cohort and nested case-control study. A total of 96 eligible patients with COVID-19 in convalescence were enrolled from Beijing Youan Hospital and Beijing Huimin Hospital and followed up from the hospital discharged day. Patients were divided into the CM (64 cases) and the control groups (32 cases) based on the treatment with or without CM and followed up at 14, 28, 56, and 84 days after discharge. In the CM group, patients received the 28-day CM treatment according to two types of CM syndrome. Improvements in clinical symptoms, CM syndrome, and absorption of lung inflammation were observed.@*RESULTS@#All the 96 patients completed the 84-day follow-up from January 21 to March 28, 2020. By the 84th day of follow-up, respiratory symptoms were less than 5%. There was no significant difference in the improvement rates of symptoms, including fatigue, sputum, cough, dry throat, thirst, and upset, between the two groups (P>0.05). Totally 82 patients (85.42%) showed complete lung inflammation absorption at the 84-day follow-up. On day 14, the CM group had a significantly higher absorption rate than the control group (P<0.05) and the relative risk of absorption for CM vs. control group was 3.029 (95% confidence interval: 1.026-8.940). The proportions of CM syndrome types changed with time prolonging: the proportion of the pathogen residue syndrome gradually decreased, and the proportion of both qi and yin deficiency syndrome gradually increased.@*CONCLUSIONS@#Patients with COVID-19 in convalescence had symptoms and lung inflammation after hospital discharge and recovered with time prolonging. CM could improve lung inflammation for early recovery. The types of CM syndrome can be transformed with time prolonging. (Registration No. ChiCTR2000029430).

ABSTRACT

OBJECTIVE@#To investigate the biological function of Cysteine rich (CysR) domain of a disintegrin and metalloprotease with thrombospondin type 1 repeats-13 (ADAMTS13) on cleavage of von Willebrand factor (vWF) and provide experimental evidence for exploring the pathogenesis of thrombotic thrombocytopenic purpura (TTP).@*METHODS@#The six amino acids (EDGTLS) in ADAMTS13 CysR domain were point mutated one by one, and the mutant ADAMTS13 proteins were expressed and purified. The cleavage products of vWF polymer by wild-type or mutant ADAMTS13 under denaturing condition or shear stress were separated by 1% SeaKem HGT agarose gel and detected by Western blot.@*RESULTS@#The mutant ADAMTS13 plasmids (M1: Glu515Ala; M2: Asp516Ala; M3: Gly517Ala; M4: Thr518Ala; M5: Leu519Ala; M6: Ser520Ala) were successfully constructed and the proteins of wild-type and mutant ADAMTS13 were purified. Wild-type ADAMTS13 almost completely cleaved the vWF polymer under denaturing condition, while the cleavage activity of M1 mutant was significantly reduced in the same condition (P<0.01). The cleavage activity of M1 mutant of ADAMTS13 was also significantly reduced compared with that of the wild-type under shear stress (P<0.01). The activity of M1 mutant to cleave the FRETS-vWF73 was dramatically reduced compared with that of wild-type ADAMTS13. However, the binding ability of M1 mutant to vWF was similar with that of wild-type ADAMTS13.@*CONCLUSION@#The CysR domain of ADAMTS13 plays an important role in the digestion of vWF under denaturing condition and shear stress. The Glu515 amino acid residue might be an important site for substrate recognition.

ABSTRACT

Objective:To study the protective effect of different doses of single-flavored Coptis, Magnoliae Officinalis Cortex, and their compatibility on ulcerative colitis (UC) model rats and the colonic B lymphoblastoma-2 associated X protein (Bax) and cysteine-containing aspartame-3(Caspase-3) protein, inflammatory cytokines, and other expressions. Method:The 120 healthy adult SD rats were randomly divided into blank group, model group, sulfasalazine group, Coptidis Rhizoma 2.00, 1.00, 0.50 g·kg-1 group, Magnoliae Officinalis Cortex 2.00, 1.00, 0.50 g·kg-1 group, Coptidis Rhizoma combine with Magnoliae Officinalis Cortex 4.00, 2.00, 1.00 g·kg-1 group, 12 groups with 10 rats in each group. The UC model was prepared by 2,4, 6-trinitrobenzene sulfonic acid/ethanol (TNBS/ethanol). After 24 h of modeling, the rats were gavaged at 10 mL·kg-1 for one time/d. After modeling, the mental state, activity state, hair luster, stool characteristics, and blood in the stool of each group were observed. After continuous administration for 6 days, colon tissues and spleen were taken after the last administration for 24 h. The ratio of colonic weight to length and spleen index was calculated. The degree of colonic injury was evaluated according to the colonic mucosal injury index (CMDI) score criteria. the histopathological observation was performed using hematoxylin-eosin staining (HE). The expression levels of tumor necrosis factor (TNF)-α, interleukin-6 (IL-6), interleukin-10 (IL-10), and myeloperoxidase (MPO) in the serum of Coptidis Rhizoma 2.00 g·kg-1 group, Magnoliae Officinalis Cortex 2.00 g·kg-1 group, Coptidis Rhizoma combine with Magnoliae Officinalis Cortex 4.00 g·kg-1 were detected by enzyme-linked immunosorbent assay(ELISA) in blank group and model group. Western blot was used to detect the expression of Bax and Caspase-3 proteins in the colon of rats. Result:Compared with blank group, rats in model group were sluggish and less active. The colon weight-length ratio, spleen index, CMDI, and colon tissue pathological damage increased significantly, and the expression of serum TNF-α, IL-6, and MPO increased significantly. Serum IL-10 expression levels were extremely significantly reduced (P<0.01). Compared with model group, the sulfasalazine group, the Coptidis Rhizoma 2.00, 1.00 g·kg-1 group, the Magnoliae Officinalis Cortex 2.00 g·kg-1 group, and the three-dose groups of Coptidis Rhizoma combine with Magnoliae Officinalis Cortex, their colon weight-length ratio and CMDI were significantly reduced (P<0.05,P<0.01). The colon weight length ratio and CMDI index of the Coptidis Rhizoma 0.50 g·kg-1 group, Magnoliae Officinalis Cortex 0.50 and 1.00 g·kg-1 group were not significantly different from the model group but compared with Coptidis Rhizoma and Magnolia 0.50 g·kg-1 group, the ratio of colon weight to length in the group of Coptidis Rhizoma combine with Magnoliae Officinalis Cortex 1.00 g·kg-1 group was significantly reduced (P<0.01). Compared with model group, the spleen index of the sulfasalazine group, the Coptidis Rhizoma 2.00 g·kg-1, and the Coptidis Rhizoma combine with Magnoliae Officinalis Cortex 4.00 g·kg-1 group were significantly lower (P<0.05), compared with model group, the sulfasalazine group, Coptidis Rhizoma 2.00, 1.00 g·kg-1 and Magnoliae Officinalis Cortex 2.00 g·kg-1, thre dose groups of Coptidis Rhizoma combine with Magnoliae Officinalis Cortex can significantly improve the depth and scope of histopathological damage and tissue necrosis. Compared with the model group, the preferred Coptidis Rhizoma 2.00 g·kg-1 group, Magnoliae Officinalis Cortex 2.00 g·kg-1 group, Coptidis Rhizoma combine with Magnoliae Officinalis Cortex 4.00 g·kg-1 group serum TNF-α, IL-6, MPO expression levels are extremely significantly reduced, the level of IL-10 increased significantly (P<0.01).Compared with blank group, the expression of  Bax and Caspase-3 protein in the colon of model group was significantly increased (P<0.01). Compared with model group, the expression of Bax and Caspase-3 protein in preferred Coptidis Rhizoma 2.00 g·kg-1 group and Magnoliae Officinalis Cortex 2.00 g·kg-1 group, Coptidis Rhizoma combine with Magnoliae Officinalis Cortex 4.00 g·kg-1 group were significantly reduced (P<0.01). Conclusion:The compatibility of single-flavored Coptidis Rhizoma, Magnoliae Officinalis Cortex, and Coptidis Rhizoma combine with Magnoliae Officinalis Cortex may improve the pathology of UC model rats induced by TNBS/ethanol by down-regulating the expression of Bax and Caspase-3 protein, inhibiting the release of inflammatory cytokines and promoting the release of anti-inflammatory factors injury, it plays a role in protecting colonic mucosa. The compatibility effect of Coptidis Rhizoma and Magnoliae Officinalis Cortex is better than that of single medicine, and Coptidis Rhizoma has a tendency to be better than Magnoliae Officinalis Cortex.

ABSTRACT

The family of flavonoid 3-O-glucosyltransferase catalyzes the modification of anthocyanin from unstable-structure to stable-structure. In this study,based on homology cloning and transcriptome library,we isolated the full-length c DNA of UDP-glucose: flavonoid 3-O-glucosyltransferase( named SmUF3GT) from the flower tissues of S. miltiorrhiza. This gene was consisted of 1 353 bp open reading frames( ORF) encoding 450 amino acids. And the SmUF3GT protein was performed for the bioinformatic analysis. Our results showed that the protein was preliminary localized in the Golgi and peroxisome of cytosol,as well as plasma membrane and cell nuclear.QRT-PCR analyses indicated that SmUF3GT expressed differently in all tissues and organs but roots of S. miltiorrhiza and S. miltiorrhiza f.alba. During floral development,the expression of SmUF3GT showed a trend of rising fist and then down in purple-flower Danshen,whereas decreasing sharply fist and then slowly in white-flower Danshen. The present study provides basic information for further research on the network of synthesis and accumulation of flavonoids in S.miltiorrhiza.

ABSTRACT

Aberrant oxidative metabolism in cells is one of the hallmarks of cancer. Overproduction of reactive species promotes carcinogenesis by inducing genetic mutations and activating oncogenic pathways, and thus, antioxidant therapy is considered as an important strategy for cancer prevention and treatment. Caveolin-1 (Cav-1), a constituent protein of caveolae, is involved in not only the formation of the caveolae, vesicular transport, maintaining cholesterol homeostasis directly, but also many cellular physiological and pathological processes including growth, regulation of mitochondrial antioxidant level, apoptosis and carcinomas by interacting with a lot of signaling molecules through caveolin scaffolding domain. Cav-1 has also been shown to mediate tumor genesis and progression through oxidative stress modulation, while Cav-1-targeted treatment could scavenge the reactive species. Intracellular reactive species could modulate the expression, degradation, post-translational modifications and membrane trafficking of Cav-1. More importantly, emerging evidence has indicated that multiple antioxidants could exert antitumor activities in cancer cells by modulating the signaling of Cav-1. This paper reviewed the research progresses on the roles of Cav-1 and oxidative stress in tumorigenesis and development, and would provide new insights on designing strategies for cancer prevention or treatment.

ABSTRACT

Objective:To explore the effect of Taiji Quan on the sleep quality of patients with chronic insomnia disorder (CID) and its mechanism. Methods:From January, 2015 to December, 2017, 31 patients with CID were enrolled in the sleep disorder clinic. Before and 24 weeks after Taiji Quan exercise, the Pittsburgh Sleep Quality Index (PSQI) was used to assess their sleep quality, the serum levels of tumor necrosis factor (TNF)-α, TNF-β, soluble tumor necrosis factor receptor (sTNF-R)1 and sTNF-R2 were detected with protein chip, and the correlation between the total score of PSQI and the serum levels of TNF-α, TNF-β, sTNF-R1 and sTNF-R2 were analyzed after exercise. Results:After Taiji Quan exercise, the scores of PSQI factors (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, daytime dysfunction) and the total score of PSQI decreased (t > 4.080, P < 0.05). The serum levels of TNF-α and TNF-β decreased (t > 13.580, P < 0.01), however, the serum levels of sTNF-R1 and sTNF-R2 significantly increased (t > 160.189, P < 0.001). The serum levels of TNF-α and TNF-β were positively correlated with the total score of PSQI (r > 0.638, P < 0.001), while the serum levels of sTNF-R1 and sTNF-R2 were negatively correlated with the total score of PSQI (r > 0.532, P<0.001). Conclusion:Taiji Quan exercise could help to improve the sleep quality of patients with CID. The mechanism may be related to the decrease of the serum levels of TNF-α and TNF-β, and the increase of the serum levels of sTNF-R1 and sTNF-R2.

ABSTRACT

Qi, blood and the meridians are fundamental concepts in Chinese medicine (CM), which are components of the human body and maintain physiological function. Pathological changes of qi, blood and meridians may lead to discomfort and disease. Treatment with acupuncture or herbal medicine aims to regulate qi and blood so as to recover normal function of the meridians. This paper explores the nature of qi as well as compares and correlates them with the structures of the human body. We propose a conceptualization of qi as being similar to the interstitial fluid, and the meridians as being similar to interstitial space of low hydraulic resistance in the body. Hence, qi running in the meridians can be understood as interstitial fluid flowing via interstitial space of low hydraulic resistance.

ABSTRACT

The study was designed to explore the effects of HS060098 on activation of peroxisome proliferator-activated receptors (PPARα, γ and δ) and in the down-regulation of hyperlipidemia in golden hamster. Luciferase gene reporters of PPARα, PPARγ and PPARδ were constructed in HepG2 cells and the green fluorescent protein (GFP) was used as an internal reference. Transfected cells were then cultured with various concentrations of HS060098 for 24 h. The peroxisome proliferator-response element luciferase activity was determined by the dual-luciferase reporter gene assay system. To investigate the lipid-lowering effect of HS060098, hyperlipidemic golden hamsters fed by high-diet were administered orally with HS060098 through prophylactic and therapeutic approaches respectively. The levels of blood lipids such as total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and fat index in hamsters were evaluated. The results showed that HS060098 was a potent activator of PPAR δ with a good selectivity and the median effective concentration (EC 50) is 0.01 μmol·L-1, while no obvious PPARα and PPARγ activation was observed. In the golden hamster, oral administration of HS060098 (5, 10, 20 mg·kg-1·d-1) for 2 weeks, led to a significant decrease the concentrations of plasma TC, TG, LDL-C and fat index (PPPPδ agonist with a significant activity in the prevention and therapy of hyperlipemia in golden hamster.

ABSTRACT

To study the correlation between the spatial cognitive impairment and different subtypes of estrogen receptor α (ERα) of hippocampus in diabetic mice, we used alloxan (intraperitoneal injection) to induce type 1 diabetes in male Kunming mice and compared the spatial cognitive ability of the model mice with that of control mice through Morris water maze test. Meanwhile, using Western blot, we detected the protein expressions of ER-α36, ER-α66, caveolin-1, PKCα, cAMP-response element binding protein 2 (CREB2), and synaptophysin (Syn) in the hippocampus of the mice. The results showed that on the 3rd and 5th days of training, the ability of spatial learning and memory in the diabetic mice was significantly inferior to that of the control mice (P < 0.05). In the diabetic mice, the protein expressions of caveolin-1 and PKCα were decreased (P < 0.05), but ER-α66 expression was unaffected, while ER-α36 and CREB2 expressions were significantly increased (P < 0.05) compared with those of the control mice. The results suggest that abnormal expression of ER-α36 and related signal molecules may be important factors for diabetes-induced spatial cognitive impairment.

ABSTRACT

Caveolin-1 (Cav-1), as an important structural protein of caveolae, has been proven to be correlated with several signal transduction pathways. Recent studies have shown that Cav-1 may play a critical role in response to DNA damage in irradiated pancreatic cancer cells. However, it is not known whether down-regulation of Cav-1 is required to enhance the damage of other kinds of human cells exposed to X-radiation. In this study, the role of Cav-1 in Chang liver cell line (CHL) exposed to X-radiation was investigated. Cav-1 knockdown cell line (CHL-CAV7) was stably established by the siRNA plasmids transfection, and Cav-1 expression was suppressed by 60%, compared with that of control group (CHL-C) which was transfected with non-targeting plasmids. Cellular survival ability and the expressions of proteins related to DNA damage and repair were examined by colony formation assay and Western blot, respectively. Down-regulation of Cav-1 expression induced a significant decrease of the survival rate in CHL-CAV7 cells exposed to 8 and 10 Gy X-radiation. Compared with CHL-C cells, CHL-CAV7 cells showed increased γH2AX expression, as well as decreased p-ATM, DNA-dependent protein kinase, catalytic subunit (DNA-PKcs) and p53 protein expressions when treated with X-radiation. Meanwhile, the colocalization of Mdm2 and Cav-1 was decreased in CHL-CAV7 cells compared with that in CHL-C cells. These results suggest that the down-regulation of Cav-1 may aggravate DNA damage of CHL cells through reducing the interaction of Cav-1 and Mdm2, which results in the promotion of p53 degradation.

In the present study, we used a proteomics approach based on a two-dimensional electrophoresis (2-DE) reference map to investigate protein expression in the ovarian tissues of pubertal Swiss-Webster mice subjected to carbon ion radiation (CIR). Among the identified proteins, ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) is associated with the cell cycle[1] and that it influences proliferation in ovarian tissues. We analyzed the expression of UCH-L1 and the proliferation marker proliferation cell nuclear antigen (PCNA) following CIR using immunoblotting and immunofluorescence. The proteomics and biochemical results provide insight into the underlying mechanisms of CIR toxicity in ovarian tissues.

ABSTRACT

Chinese patent medicines for orthopedics are among the hotspot and difficulty in the rational medication of traditional Chinese medicine (TCM), because they mostly contain toxic medicinal herbs and oriented to special patients. According to the hospital pharmacy practices and the therapeutic theories of TCM, this paper focused on a novel model of rational drug use of Chinese patent medicine for orthopedics based on the principles of ″syndrome-dosage-toxicity differentiation″. We also proposed relevant specifications for guiding their clinical use. Firstly, we proposed a list of the primary clinical application characteristics for rational drug use of orthopedic TCMs, including the syndromes of patient, the dosage of medicine and the toxic ingredients in medicine. Secondly, a database was established for recording the package inserts of all of the 81 orthopedic patent medicines in our hospital, and 2 000 retrospective recipes were analyzed for looking for the high-frequency medicines and common irrational factors. Then clinical case reports involving the adverse reactions and side effects of related drugs were searched from CNKI, VIP and WanFang databases. Then the key information for rational application of each medicine was extracted from these resources and some survey questionnaires. Finally, we established a guide named instructions for clinical use of orthopedic Chinese patient medicines (ICUOCPM) after the discusstion with experts. According to the effect after the practice in hospital for 2 months, the proposed principles of ″syndrome-dosage-toxicity differentiation″ in this paper were believed to be the core elements and the most important clinical monitoring points in TCM for orthopedic patents. It would provide innovative ideas, theoretical guarantee and data support for the development of TCM clinical pharmacy.
