ABSTRACT

OBJECTIVE To establish t he method for determining the concentrations of fluoxetine ,norfluoxetine and sertraline in human placental perfusate method and their placental permeability. METHODS Using glyburide as internal standard ,the samples were pretreated by protein precipitation method and detected by ultra-fast liquid chromatograph-mass spectrometer/mass spectrometer (UFLC-MS/MS). The determination was performed on Synergi TM Hydro-RP 80A LC column with mobile phase consisted of water (containing 0.1% formic acid )-acetonitrile(containing 0.1% formic acid )at the flow rate of 0.70 mL/min,with a gradient elution. The column temperature was set at 40 ℃,and sample size was 5 μL. Detection was performed with electrospray ionization source in multipl e reaction monitoring mode . The ion pairs for quantitative analysis we re m/z 309.9→148.1(fluoxetine),m/z 296.0→134.4 (-167), (norfluoxetine),m/z 306.1→159.0 (sertraline),m/z 493.9→ No.2018FE001(-207),(internal standard ). The perfusion model of singal placenta under bidrectional cardiopulmonary bypass was established. Fluoxetine (160 ng/mL),norfluoxetine(160 ng/mL), sertraline(100 ng/mL)and antipyrine (positive control ,ng/mL)were added into the maternal perfusate. The concen- 65324888 trations of fluoxe tine, norfluoxetine and sertrali ne were measured by above UFLC-MS/MS at 0,10,20,30,45,60,90,120,150 and 180 min of circulation ,and the placental permeability was calculated. RESULTS The linear range of fluoxetine ,norfluoxetine and sertraline were 5.00-500 ng/mL(all r> 0.990),and the lower limits of quantification were all 5.00 ng/mL. The RSDs of intra-day and inter-day were all less than 14.0%, and relative error ranged -9.6% to 14.7%. The relative error of stability test was -4.0% to 11.0%;the residual effect ,extraction method and matrix effect did not affect the quantitative analysis of the substance to be tested. Totally 31 perfusion model of human placenta under cardiopulmonary bypass were successfully established ,including 15 fluoxetine and norfluoxetine perfusion ,10 sertraline perfusion and 6 antipyrine perfusion. After 3 hours of perfusion ,the average placental permeability of fluoxetine , norfluoxetine and sertraline were (8.74 ± 1.67)% ,(10.70 ± 4.81)% ,(5.90 ± 1.25)% ,respectively. CONCLUSIONS The established UPLC-MS/MS is simple ,sensitive and accurate. It can be used for determination of fluoxetine ,norfluoxetine and sertraline in human placental perfusate. Fluoxetine ,norfluoxetine and sertraline can pass through the placenta ,but sertraline has a lower placental permeability.

ABSTRACT

Objective:To investigate the effects of Di'ao Xinxuekang (DXXK) on NLRP3 inflammasome in mouse RAW264.7 macrophages and thoracic aorta of rats with atherosclerosis (AS), so as to explore its anti-AS mechanism. Method:RAW264.7 cells were stimulated with oxidized low density lipoprotein (ox-LDL) and then intervened with MCC950 and DXXK. The contents of tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>) and interleukin-1<italic>β</italic> (IL-1<italic>β</italic>) were determined by enzyme linked immunosorbent assay (ELISA). The mRNA and protein expression levels of Nod-like receptor protein 3 (NLRP3), inflammasome adaptor protein apoptosis-associated speck-like protein containing CARD (ASC), and cysteine-dependent aspartate-directed protease-1 (Caspase-1) were detected by real-time polymerase chain reaction (Real-time PCR) and Western blotting. Sixty male SD rats were randomly divided into the normal group, model group, atorvastatin group (2.0 mg·kg<sup>-1</sup>), as well as high-, medium-, and low-dose (100, 30, and 10 mg·kg<sup>-1</sup>) DXKK groups, with 10 rats in each group. The rats were exposed to the high-fat diet and vitamin D<sub>2</sub> for inducing AS. The blood lipid level was measured using an automatic biochemical analyzer, followed by the calculation of AS index (AI). The contents of serum TNF-<italic>α</italic> and IL-1<italic>β</italic> were determined by ELISA, and the mRNA and protein expression levels of NLRP3, ASC, and Caspase-1 in thoracic aorta were assayed by Real-time PCR and Western blotting. HE staining and Sirius red staining were conducted to observe the pathomorphological changes in the abdominal aorta and aortic sinus. Result:Compared with the normal group, the model group exhibited significantly increased TNF-<italic>α</italic> and IL-1<italic>β</italic> contents and up-regulated NLRP3, ASC, and Caspase-1 mRNA and protein expression in RAW264.7 cells (<italic>P</italic><0.01). The above indexes in each drug administration group were significantly reduced in contrast to those in the model group (<italic>P</italic><0.05, <italic>P</italic><0.01). The comparison with the model group showed that cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and AI in each DXXK group significantly declined, while the high-density lipoprotein cholesterol (HDL-C) was significantly elevated (<italic>P</italic><0.05, <italic>P</italic><0.01). The levels of serum TNF-<italic>α</italic> and IL-1<italic>β</italic> and the mRNA and protein expression levels of NLRP3, ASC, and Caspase-1 in the thoracic aorta were decreased (<italic>P</italic><0.05, <italic>P</italic><0.01). Abdominal aortic lesions and fibrous hyperplasia of aortic sinus were significantly improved. Conclusion:DXXK has a significant anti-AS effect, which is possibly related to the inhibition of NLRP3 inflammasome.

ABSTRACT

Objective:To study the effect of Wenjing Huayu Zhitong therapy (Xiangyan Zhitong prescription, XZP) on the mitogen activated protein kinase (MAPK)/extracelluar regulated protein kinase (ERK) signaling pathway of primary dysmenorrhea (PD) rats, and explore the pathogenesis of PD and the mechanism of action of Wenjing Huayu Zhitong therapy. Method:Forty-eight female SPF-grade Wistar rats were randomly divided into blank group,model group, western medicine group, low-dose XZP group, medium-dose XZP group, and high-dose XZP group, with 8 rats in each group. In addition to the blank group, dysmenorrhea rat model with cold coagulation and blood stasis syndrome was established by cold stimulation combined with estradiol benzoate and oxytocin. The rats in the blank group,model group,western medicine group, low-dose XZP group, medium-dose XZP group, and high-dose XZP group were given distilled water, distilled water,0.06 g·kg<sup>-1</sup> ibuprofen, 6.55 g·kg<sup>-1</sup> XZP, 13.09 g·kg<sup>-1</sup> XZP, and 26.18 g·kg<sup>-1</sup> XZP, respectively, by gavage for 6 days. The writhing latency and writhing frequency of rats were recorded within 30 min after oxytocin injection.Western blot was used to detect the protein expression of B-Raf, mitogen activates extracellular regulated kinases1/2 (MEK1/2), extracellular regulated kinases1/2 (ERK1/2), p-MEK1/2, p-ERK1/2, c-Jun, and cyclooxygenase-2 (COX-2) in rat uterus. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to detect the mRNA expression of B-Raf, MEK1, MEK2, ERK1, ERK2, c-Jun, and cyclooxygenase-2 (COX-2) in rat uterus. Result:Compared with the model group,the treatment groups showed insignificantly prolonged writhing latency and significantly reduced writhing frequency (<italic>P</italic><0.01). On the 6<sup>th</sup> day of modeling, there was no significant difference in the quantitative scores of symptoms and signs among the treatment groups. On the 12<sup>th</sup> day of modeling, the scores changed little in the western medicine group and the low-dose XZP group and decreased significantly in the medium- and high-dose XZP groups (<italic>P</italic><0.01) compared with those in the model group. Compared with those in the blank group, the protein and mRNA levels of p-MEK1/2, p-ERK, B-Raf, c-Jun, and COX-2 in the model group were significantly up-regulated (<italic>P</italic><0.01). Compared with those in the model group, the protein and mRNA levels of p-MEK1/2, p-ERK1/2, B-Raf, c-Jun, and COX-2 in the western medicine group, medium-dose XZP group, and high-dose XZP group were significantly down-regulated (<italic>P</italic><0.05,<italic>P</italic><0.01). Conclusion:The mechanism of Wenjing Huayu Zhitong therapy in treating PD with cold coagulation and blood stasis syndrome may be related to the down-regulation of MAPK/ERK signaling pathway.

ABSTRACT

The recycling of traditional Chinese medicine (TCM) wastes is an important research topic to be solved urgently in the industrialization of TCM resources. Rhei Radix et Rhizoma is a bulk Chinese herb mainly derived from Rheum palmatum,R. tanguticum,and R. officinale. At present,these three medicinal plants have been cultivated on a large scale and widely used in the fields of medicine,health care,food,cosmetics,and veterinary medicine,with an annual demand of more than 5 500 tons(1 ton=1 000 kg). However,a large number of wastes such as non-medicinal parts and residues produced in the production and deep processing are discarded because there is no effective way of utilization,resulting in serious waste of resources and environmental pollution. The non-medicinal parts contain not only the chemical components and pharmacological effects similar to those of roots and rhizomes but also a variety of amino acids,mineral elements,and conventional nutrients. They have a long history of use,and the content of some resource components is higher than that in roots and rhizomes. In particular,their stems and leaves exhibit great potential to be consumed as food and medicine due to high safety. Besides,the content of anthraquinones in Rhei Radix et Rhizoma residue is high and it possesses good antibacterial activity. It can be seen that the waste from the industrialization of Rhei Radix et Rhizoma has high utilization value. Hence,based on the relevant literature and investigation on the application of producing areas in China and abroad,the paper summarized the utilization status of their medicinal and non-medicinal parts,the waste production in the industrialization,as well as the active substances and utilization ways and put forward the multi-level and multi-path utilization strategy of Rhei Radix et Rhizoma wastes,in order to provide reference for the rational development and application of Rhei Radix et Rhizoma resources and promote the effective utilization and green development of the corresponding wastes.

ABSTRACT

Nonalcoholic fatty liver disease (NAFLD) is a metabolic stress-induced liver injury characterized by excessive lipid accumulation in hepatocytes, which is closely related to insulin resistance and genetic susceptibility. It falls into the category of "liver lump" in traditional Chinese medicine (TCM). NAFLD affects about 25% of the population worldwide and has become a major burden of the world health care system. However, its exact pathogenesis remains unclear. Conducting the basic research on NAFLD is of great clinical significance and social value. As an important tool for NAFLD research, animal model plays a particularly important role in clarifying the pathophysiological mechanism of NAFLD. In recent years, the modeling methods for NAFLD in China and abroad have been constantly updated, and in particular, certain progress has been made in the duplication of TCM syndrome models. By consulting and sorting out the relevant literature published in recent years in China and abroad, the author summarized the replication methods of NAFLD animal models. This paper reviewed the advantages and disadvantages of models established via dietary induction (high-fat feed, high-fat and high-fructose feed, high-fat and high-cholesterol feed, and methionine choline-deficient feed), models with genetic defects [leptin-deficiency (Lepob/Lepob), autosomal recessive diabetes gene homozygous deficiency (ob/ob), Alms1 gene (foz/foz) mutation, and FATZO mice] and exposure to special diets, and models for TCM syndromes (liver depression and spleen deficiency syndrome, phlegm-dampness syndrome, blood stasis syndrome, combined phlegm and stasis syndrome, and qi stagnation and blood stasis syndrome), in order to provide reference for the preparation of more scientific, reasonable, economical, and convenient animal models of NAFLD, thus laying a foundation for in-depth study of the pathogenesis, prevention, and treatment of NAFLD.

ABSTRACT

Objective:To analyze the clinical application and main roles of Cardiopulmonary Exercise Test (CPET) in patients with lung cancer based on the theory of the World Health Organization Family International Classifications (WHO-FICs). Methods:An evidence-based scoping review was implemented. Literatures related to the applications of CPET in patients with lung cancer were retrieved, from databases including PubMed, Web of Science, CNKI and Wanfang data; from January, 2013 to April, 2021. The indications, contraindications, motor dysfunction, pulmonary rehabilitation interventions, evaluation methods and indicators, and the environment factors of CPET applicated in patients with lung cancer was reviewed based on WHO-FICs framework. Results:This paper analyzed the included literatures from five aspects: the type of disease, functioning, pulmonary rehabilitation exercise interventions, functioning evaluation and environment factors. The major diseases included different pathological types of non-small cell lung cancer (NSCLC) (2C25), and the most common complication of lung cancer was chronic obstructive pulmonary disease (COPD) (CA22). The obstacles of CPET conducted in lung cancer patients mainly included physical structure and functional activities and participation obstacles. Pulmonary rehabilitation based on the CPET was divided into therapeutic, preventive and health promotion interventions. The evaluation tools and indicators were oxygen intake, carbon dioxide output, oxygen pulse, heart rate, blood pressure, electrocardiogram, Borg Scale, 6-minute Walking Test, the MOS Item Short Form Health Survey (SF-36), etc. The classification and description of environmental factors were provided. Conclusion:The application of CPET in lung cancer mainly included preoperative evaluation and prognosis prediction, exercise prescription formulation and exercise effect assessment, anti-cancer treatment impact assessment. Based on WHO-FICs theory system, the applications of CPET mainly involved NSCLC, and COPD was the most common complication of lung cancer. Pulmonary rehabilitation for lung cancer is function- and demand-oriented. Based on CPET evaluation results, individualized therapeutic, preventive and health promotion interventions are conducted to improve the overall function and optimize the health outcomes of patients with lung cancer.

ABSTRACT

OBJECTIVE@#To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants.@*METHODS@#The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP.@*RESULTS@#The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation (@*CONCLUSIONS@#A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.

ABSTRACT

Purpose@#Systemic inflammatory response is a critical factor that promotes the initiation and metastasis of malignancies including pancreatic cancer (PC). This study was designed to determine and compare the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and fibrinogen-to-albumin ratio (FAR) in resectable PC and locally advanced or metastatic PC. @*Materials and Methods@#Three hundred fifty-three patients with resectable PC and 807 patients with locally advan-ced or metastatic PC were recruited in this study. These patients were classified into a training set (n=758) and a validation set (n=402). Kaplan-Meier survival plots and Cox proportional hazards regression models were used to analyze prognosis. @*Results@#Overall survival (OS) was significantly better for patients with resectable PC with low preoperative PLR (p=0.048) and MLR (p=0.027). Low FAR, MLR, NLR (p < 0.001), and PLR (p=0.003) were significantly associated with decreased risk of death for locally advanced or metastatic PC patients. FAR (hazard ratio [HR], 1.522; 95% confidential interval [CI], 1.261 to 1.837; p < 0.001) and MLR (HR, 1.248; 95% CI, 1.017 to 1.532; p=0.034) were independent prognostic factors for locally advanced or metastatic PC. @*Conclusion@#The prognostic roles of FAR, MLR, NLR, and PLR in resectable PC and locally advanced or metastatic PC were different. FAR showed the most prognostic power in locally advanced or metastatic PC. Low FAR was positively correlated with OS in locally advanced or metastatic PC, which could be used to predict the prognosis.

ABSTRACT

Objective:To analyze the clinical characteristics and risk factors of clopidogrel resistance after intracranial arterial stent implantation in patients with ischemic cerebrovascular disease.Methods:Retrospective case-control study was used.A total of 360 patients with ischemic cerebrovascular disease hospitalized in Beijing Tiantan Hospital from January 2017 to December 2018 were selected.All patients received intracranial arterial stenting and received double anti-platelet drugs after operation.Patients were divided into clopidogrel resistance group and non-resistance group according to the inhibition rate of platelet aggregation measured by thromboelastography.Clinical data and laboratory indicators of patients in the two groups were compared using two independent sample T tests and Mann-Whitney U tests, and possible risk factors of clopidogrel resistance were analyzed by Logistic regression.Results:White blood cell (WBC) count, neutrophils count, lymphocyte count, cholesterol, LDL cholesterol, and serum homocysteine levels in the clopidogrel non-resistant group were (6.58±1.45)×10 9/L, (4.01±1.05)×10 9/L, 1.83(1.49, 2.23)×10 9/L, (3.63±0.85) mmol/L, 1.93(1.53, 2.31) mmol/L, and 14.3(11.80, 17.00) μmol/L, respectively.Compared with the clopidogrel non-resistant group, the WBC count, neutrophils count, lymphocyte count, cholesterol, LDL cholesterol and serum homocysteine levels in the clopidogrel resistant group were all higher (7.19±1.53) ×10 9/L, (4.40±1.05) ×10 9/L, 2.03(1.63, 2.58)×10 9/L, (4.02±0.99) mmol/L, 2.04(1.68, 2.78) mmol/L and 15.90(12.25, 22.20) μmol/L, respectively.The difference was statistically significant ( t=3.277, t=2.867, Z=2.457, t=3.409, Z=2.705 and Z=2.220, respectively; P value were 0.001, 0.004, 0.014, 0.001, 0.007 and 0.026, respectively). Logistic regression analysis showed that high serum homocysteine ( OR=1.031, 95% CI 1.006-1.057, P=0.015) was an independent risk factor for clopidogrel resistance. Conclusion:Patients with clopidogrel resistance have high leucocyte, blood lipid, homocysteine and other clinical characteristics.High serum homocysteine is an independent risk factor for clopidogrel resistance.

ABSTRACT

Objective:To explore the correlation between cognitive impairment and intestinal mucosal barrier injury in rats after chronic cerebral hypoperfusion(CCH), and to quantitatively analyze the changes in cognitive behavior of experimental rats caused by chronic cerebral hypoperfusion, as well as the expression changes of the intestinal mucosal barrier claudin-1 and osteopontin.Methods:Thirty male SD rats were randomly divided into CCH group ( n=15) and sham operation (SHAM) control group ( n=15). The CCH model was established by permanent ligation of bilateral common carotid arteries.Rats in the SHAM group only separated the common carotid artery without ligation.Four weeks later, open field experiment, object discrimination experiment, and Morris water maze experiment were used to detect the emotional arousal ability, the ability to explore new things, and the ability of spatial learning and memory in rats.HE staining and immunofluorescence experiments were conducted to detect the damage of rat ileum tissue.Western blot was used to detect OPN expression, and ELISA was used to detect serum OPN.SPSS 23.0 and GraphPad 8.0 statistical softwares were used to process the data, and the t-test and repeated measures one-way analysis of variance were used for data analysis. Results:In the open field test, compared with the SHAM group ((28.70±10.70)times, (1 030.45±81.51)cm), the number of standing and total exercise distance of rats in the CCH group ((16.70±7.13)times, (736.64±136.71)cm) were decreased( t=1.59, 4.16, both P<0.05). In the object discrimination experiment, the discrimination index of rats in the CCH group (0.44±0.26) was lower than that of the SHAM group (0.91±0.07, t=-7.76, P<0.05). Morris water maze positioning navigation experiment showed that the group main effect and time main effect were both significant( F=383.36, 153.87, P<0.05). Simple effect analysis showed that, compared with the SHAM group, the escape latency and total swimming distance of rats in CCH group increased( P<0.05). Space exploration experiment showed that, compared with SHAM group ((7.20±1.81)times, (9.96±2.95)s), the number of crossings of rats in CCH group ((3.00±0.82)times) decreased, and the incubation period ((29.70±6.28)s) was prolonged( t=4.65, 7.04, both P<0.05). The intestinal mucosal pathology score of SHAM group ((1.98±0.34)points) was lower than that of the CCH group ((4.52±0.27)points), and the difference was significant( t=18.53, P<0.01). Immunofluorescence experiment showed that, compared with SHAM group (125 028.58±33 077.39), the cumulative optical density of claudin-1 between the intestinal epithelial cells of the CCH group(47 154.50±7 507.29) decreased( t=16.10, P<0.01). Western blot experiment showed that, compared with the SHAM group (0.38±0.11), the expression of OPN in the intestines of the CCH group (1.20±0.95) increased( P<0.05). ELISA experiment showed that, compared with the SHAM group ((3.42±0.66)μg/L), the serum OPN content of the CCH group ((14.92±1.45)μg/L) significantly increased( P<0.05). The degree of cognitive impairment was negatively correlated with intestinal mucosal epithelial claudin-1 expression and serum OPN content( P<0.01). Intestinal mucosal epithelial claudin-1 expression was negatively correlated with serum OPN content ( r=-0.952, P<0.01). Conclusion:CCH may cause obvious cognitive impairment in rats and the destruction of the intestinal mucosal barrier.Serum OPN may be a potential serological marker of CCH-induced cognitive impairment and intestinal mucosal barrier destruction in rats.

ABSTRACT

Objective:To investigate the safety and surgical treatment effect of da Vinci robot in male thyroid surgery.Methods:Clinical data of 276 male patients undergoing robotic thyroid surgery with bilateral axillo-breast approach (BABA) admitted to our hospital from Feb. 2014 to Jan. 2020 were retrospectively analyzed. They were compared with 372 male patients (open group) who had open surgery by the same team during the same time. Surgical time, the amount of fluid selitransteise after surgery, the length of hospitalization after surgery, the number of metastatic lymph node (for malignant tumor) , cosmetic effect satisfaction, injury of recurrent laryngeal nerve and decrease of parathyroid function and other related surgical complications were analyzed. SPSS 20.0 software was employed to carry out statistical analysis, the measurement data were compared with t-test, and the counting data were analyzed by χ2 test. Results:All operations were successfully completed and on one in the robot group was converted into open surgery. Compared with the open group, surgical time of the robot group (benign: 96.78±9.67min, malignant: 143.93±15.73min) was significantly longer than that of the open group (benign: 70.40±12.49min, malignant: 112.26±15.72min) ( P<0.05) , but the postoperative beauty effect of the robot group (benign: 9.62±0.33 points, malignant: 9.59±0.31 min) was better than that of the open group (benign: 5.33±0.37 points, malignant: 5.87±1.65 points) ( P<0.05) . In patients with pathological malignancy, the average age of the robot group (40.89±11.45 years) was lower than that of the open group (44.84±11.88 years) (P<0.05) . There was no significant difference in the amount of fluid induced after surgery, the length of hospital stay after surgery or the number of cases with lymph node metastasis in the two groups ( P>0.05) . There were 2 cases in the robot group and 5 cases in the open surgery group had recurrent metastasis in the side of the neck after surgery. None of the patients had permanent larynx reflux nerve damage or permanent parathyroid dysfunction. The average follow-up time was (25.36±16.13) months, ranging from 1 to 72 months. Conclusion:Compared with traditional open surgery, da Vinci robot surgery system is safe and feasible in male thyroid surgery, with better beauty effect, and provides new options for male thyroid surgery patients with neck beauty needs.

ABSTRACT

@#The antimicrobial peptide APKGVQGPNG (named YD), a natural peptide originating from Bacillus amyloliquefaciens CBSYD1, exhibited excellent antibacterial and antioxidant properties in vitro. These characteristics are closely related to inflammatory responses which is the central trigger for liver fibrosis. However, the therapeutic effects of YD against hepatic fibrosis and the underlying mechanisms are rarely studied. In this study, we show that YD improved liver function and inhibited the progression of liver fibrosis by measuring the serum transaminase activity and the expression of α-smooth muscle actin and collagen I in carbon tetrachloride-induced mice. Then we found that YD inhibited the level of miR-155, which plays an important role in inflammation and liver fibrosis. Bioinformatics analysis and luciferase reporter assay indicate that Casp12 is a new target of miR-155. We demonstrate that YD significantly decreases the contents of inflammatory cytokines and suppresses the NF-κB signaling pathway. Further studies show that transfection of the miR-155 mimic in RAW264.7 cells partially reversed the YD-mediated CASP12 upregulation, the downregulated levels of inflammatory cytokines, and the inactivation of the NF-κB pathways. Collectively, our study indicates that YD reduces inflammation through the miR-155–Casp12–NF-κB axis during liver fibrosis and provides a promising therapeutic candidate for hepatic fibrosis.

ABSTRACT

In this study, a high performance thin-layer chromatography/single quadrupole mass spectrometry QDa (HPTLC-QDa) method for robust authentication of Ganoderma lucidum, a popular and valuable herbal medicine, has been developed. This method is simple and practical, which allows direct generation of characteristic mass spectra from the HPTLC plates automatically with the application of in situ solvent desorption interface. The HPTLC silica gel plates were developed with toluene-ethyl formate-formic acid (5 : 5 : 0.2, V/V) and all bands were transferred to QDa system directly in situ using 80% methanol with 0.1% formic acid as desorption solvent. The acquired HPTLC-QDa spectra showed that luminous yellow band b3, containing ganoderic acid B/G/H and ganodeneric acid B, the major active components of Ganoderma, could be found only in G. lucidum and G. lucidum (Antler-shaped), but not in G. sinense and G. applanatum. Moreover, bands b13 and b14 with m/z 475/477 and m/z 475/491/495, respectively, could be detected in G. lucidum (Antler-shaped), but not in G. lucidum, thus allowing simple and robust authentication of G. lucidum with confused species. This method is proved to be simple, practical and reproducible, which can be extended to analyze other herbal medicines.

ABSTRACT

OBJECTIVE@#To investigate the therapeutic effect of spleen low molecular weight extracts on epileptics hydrochloride-induced leukopenia in mice and explore its mechanism.@*METHODS@#The model of leukopenia in mice was established by the injection of epirubicin hydrochloride (10 mg/kg). After the injection of chemotherapeutic drugs, leukocytopenia mice were treated with different doses of spleen low molecular weight extract, Ganoderma oral solution and recombinant granulocyte colony stimulating factor (rhG-CSF). The general survival status indicators such as body weight, coat color and athletic ability of mice in each group were recorded; the tail vein blood of mice in each group was collected and the white blood cell count in them was calculated; bone marrow of mice was taken and bone marrow smears were observed.@*RESULTS@#In the model group, the weight of the mice gradually decreased in the later period, their coat became dark and rough, and the ability to exercise decreased, while the mice in the treatment groups showed different degrees of improvement in their survival status except for the mice treated by rhG-CSF. There was no significant fluctuation in the white blood cell count of the blank control mice. After injection of epirubicin, the white blood cell count of peripheral blood in the model mice and treated mice were decreased. The white blood cell count was lower in the mice treated with high-dose low molecular weight extract and rhG-CSF than that in other experimental groups. Bone marrow smear showed that the proportion of bone marrow nucleated cells in the mice treated with the low molecular weight extract of the spleen was significantly higher than that of model mice (P<0.05).@*CONCLUSION@#The low molecular weight spleen extracts can significantly improve the hematopoietic state of mouse bone marrow, promote the proliferation of inhibited bone marrow cells, and thus has the effect of treating leukopenia in mice.

ABSTRACT

OBJECTIVE@#To investigate the application value of whole exome sequencing technology in fetuses with congenital structural abnormalities.@*METHODS@#The chromosomal abnormalities of 1147 families were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in late pregnancy or after birth were reanalyzed. Subgroups were divided according to the organs involved and whether single malformation or not. The gene regulatory network map was drawn by using string database and Cytoscape software. Fisher exact probability method was used to compare the difference of the diagnostic rate of pathogenic genes among the groups.@*RESULTS@#A total of 160 fetal cases received positive molecular diagnosed, involving 178 variant sites of 125 pathogenic genes, including 8 cases (4.9%, 8/163) by data reanalysis, and the overall positive diagnosis rate was 13.9%. Diagnostic rate was highest in the group of skeletal malformation (31.5%, 39/124) and lowest in that with thoracic malformation (0, 0/32). The gene clusters of fetal edema and intrauterine growth restriction were independent, and were not associated with the major structural malformations. The probability of each parent carrying the same recessive gene variant was 0.03 (39/1146) and 0.08 (4/53) with positive family history.@*CONCLUSION@#For fetuses with congenital structural abnormalities that are negative for conventional genetic tests, 13.9% of phenotypic associated pathogenic/likely pathogenic genetic variants can be detected by whole exome sequencing technology. Its application value for prenatal diagnosis varies in fetus with different organs involved. Reanalysis of sequencing data for cases with new phenotypes in late pregnancy or after birth can further improve the molecular diagnosis rate. Further investigations are needed to explore the related genetic mechanisms.

ABSTRACT

The medicinal plants with roots and rhizomes as the medicinal parts account for about 1/3 of Chinese medicinal herbs. Root and rhizome medicinal materials are widely used in clinical practice, whereas their wild resource reserves are insufficient to meet the market demand. With the expansion of planting areas, the formation of large-scale production areas, and the increase in planting years, diseases and insect pests of these medicinal plants, which are diverse and have broad transmission routes, strong concealment, and heavy damage, have become more and more serious. The prevention and control of these diseases and insect pests is characterized by multiple ways of pesticide application, large consumption of pesticides, susceptibility to soil barrier, difficulty in the control, and unstable control efficiency. Organophosphorus pesticides(OPPs) are widely used in the cultivation of Chinese medicinal plants because of their diverse varieties, broad-spectrum, good efficacy, and low residues, and have a positive effect on the yield and quality of Chinese medicinal materials. However, the abuse of OPPs not only increases the planting cost, but also affects the quality and safety of Chinese medicinal plants, the safety of clinical use of Chinese medicine, and the ecological safety of production areas. This paper reviewed the research and development progress of OPPs, the registration status of OPPs used in root and rhizome medicinal materials, residue limit standards, residue status, and rapid detection technology progress of OPPs. This review aims to provide research ideas and references for standardizing the use of OPPs in root and rhizome medicinal materials, reducing OPP residues, and establishing a fast, efficient, accurate, and reliable method for the detection of OPP residues in Chinese herbal medicine.
