ABSTRACT

Huachansu is a traditional Chinese medicine widely used in the clinic for cancer therapy, while the underlying mechanism is not fully clarified. This study was to investigate the targets and mechanisms of cinobufagin (CBG), an active component of Huachansu, in terms of blocking mitosis of cancer cells. Propidium iodide (PI) DNA staining was used to analyze the effect of CBG on cell cycle. The effect of CBG on mitosis of cancer cells was examined by α-tubulin and pericentrin staining after synchronization by a double thymidine block. Tubulin turbidity, tubulin polymerization and α‍-tubulin immunofluorescence assays were used to evaluate the effect of CBG on microtubule polymerization. CRISPR/Cas9 gene-editing technology was used to knockout microtubule-severing protein Katanin regulatory subunit B1 (KATNB1) in HCT116 cells, and the inhibitory effect of CBG on wild-type cells and knockout cells was measured by CCK-8. The engagement of CBG with KATNB1 was measured by CETSA and DARTS assays. The effect of CBG on KATNB1 protein and mRNA level was examined by Western blot and real-time PCR, respectively. Our data showed that CBG arrested HCT116 cell cycle at the G2/M phase, disrupted mitosis and induced centriole overduplication. CBG significantly inhibited tubulin polymerization in vitro and in vivo. The cytotoxicity of CBG inhibition on HCT116 was significantly attenuated upon KATNB1 depletion. Moreover, CBG bound to KATNB1 and decreased its protein level, while mutated KATNB1 weakened this effect. In conclusion, CBG inhibited microtubule polymerization via targeting KATNB1, thereby disrupting mitosis in cancer cells.

ABSTRACT

Cytochrome P450 reductase (CPR) is essential for the electron transport chain of cytochrome P450s, playing an indispensable role in electron transfer in vivo. In this study, one cDNA encoding cytochrome P450 reductase (Ascpr1) was identified from the callus of Aquilaria sinensis. Ascpr1 contains an open reading frame of 2 124 bp. The deduced protein is composed of 707 amino acids, with a predicted molecular weight of 78.82 kD. Phylogenetic analysis revealed that AsCPR1 is a type Ⅱ CPR protein closely related to the CPR from Theobroma cacao. Transmembrane prediction using TMHMM 2.0 indicated that the amino acids 52-71 of AsCPR1 comprise a transmembrane region. After truncating of 67 amino acid residues from N-terminal, the truncated AsCPR1 was successfully expressed in E. coli Transetta (DE3). Further purification of the recombinant AsCPR1 by affinity chromatography and determination of the enzymatic activity allowed the reducing ability of AsCPR1 to cytochrome C in vitro. The results pave the way for further study on the synthesis of defensive chemicals involved in P450s and the functions of CPR in self-defense of A. sinensis.

ABSTRACT

Objective:To analyze the correlation between human immunodeficiency virus (HIV)-1 reservoir and poor immune reconstitution of HIV/acquired immunodeficiency syndrome (AIDS) patients, and to investigate the influence of HIV-1 reservoir on the immune reconstitution.Methods:Cross-sectional survey was conducted to measure HIV-1 RNA and T lymphocyte subsets from 219 patients with HIV/AIDS who had been treated with anti-retroviral therapy (ART) for more than two years with HIV RNA lower than the limit of detection. Among them, there are 195 patients from the Sixth People′s Hospital of Zhengzhou, 12 patients from Shangqiu Municipal Hospital and 12 patients from Zhoukou Infectious Diseases Hospital. Peripheral blood mononuclear cells (PBMC) were collected and HIV-1 DNA was detected. The measurement data of normal distribution were analyzed by two independent sample t-test. The measurement data of skewness distribution were analyzed by rank sum test. Spearman′s rank correlation was used for correlation analysis. Receiver operating characteristic curve (ROC) was used to predict the predictive value of occurrence of poor immune reconstitution AIDS patients. Results:There were 121 patients with poor immune reconstitution and 98 patients with healthy immune reconstitution. HIV-1 DNA was (2.50±0.52) copies/1×10 6 PBMC in the group with poor immune reconstitution, which was significantly higher than the healthy immune reconstitution group ((2.11±0.66) copies/1×10 6 PBMC, t=4.78, P<0.001). The CD4 + T lymphocyte counts in the group with poor immune reconstitution was 192(139, 227)/μL, which was lower than that in the healthy immune reconstitution group (573(457, 730)/μL). The difference was statistically significant ( Z=12.68, P<0.001). HIV-1 DNA was reversely correlated with CD4 + T lymphocyte counts and CD4 + /CD8 + T lymphocyte ratio (after adjusting the influence of age and ART time, r=-0.277 and -0.316, respectively, both P<0.001). The area of ROC curve for HIV-1 DNA to predict poor immune reconstitution was 0.679(95% confidence interval ( CI) 0.604 to 0.750). The HIV-1 DNA threshold value was 100 copies/1×10 6 PBMC with the sensitivity of 90.13% and specificity of 42.91%. The area of ROC curve of CD4 + /CD8 + T lymphocyte ratio to predict poor immune reconstitution was 0.905 (95% CI 0.863 to 0.942). The threshold value of CD4 + /CD8 + T lymphocyte ratio was 0.536 with the sensitivity of 77.68% and specificity of 89.84%. Conclusions:There is correlation between HIV-1 DNA and poor immune reconstitution in HIV/AIDS patients. The value of HIV-1 DNA higher than 100 copies/1×10 6 PBMC and CD4 + /CD8 + T lymphocyte ratio lower than 0.536 could be used as predictor of poor immune reconstitution.

ABSTRACT

Objective:To analyze the change of macular microcirculation in early diabetic patients and its correlation with visual acuity.Methods:A cross-sectional study was performed.Seventy-five eyes from 75 patients with non-diabetic retinopathy (NDR) and 33 eyes from 33 patients with non-proliferative diabetic retinopathy (NPDR) were included in Subei People's Hospital Affiliated to Yangzhou University from December 2019 to September 2020.The patients were divided into the NDR group and NPDR group according to their condition.Another 35 eyes from 35 healthy subjects served as the control group.Optical coherence tomography angiography (OCTA) images were acquired over 3 mm×3 mm regions centered on the fovea using RTVue XR OCTA device and the data were quantified with Angio Vue software.The area, perimeter and acircularity index (AI) of the macular foveal avascular zone (FAZ), the grading of abnormal superficial and deep FAZ contour, as well as the vessel density of superficial capillary plexuses (SCP), deep capillary plexuses (DCP) and a 300 μm ring area beside FAZ (FD300) were analyzed and compared among the three groups.The correlations between these indexes and visual acuity were analyzed.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Subei People's Hospital affiliated to Yangzhou University (No.2018KY-167). Written informed consent was obtained from each subject prior to any medical examination.Results:No statistically significant differences were found in the FAZ area, FAZ perimeter and AI among the three groups ( F=1.948, P=0.146; F=2.632, P=0.075; H=5.582, P=0.061). The proportions of superficial and deep FAZ contour abnormality were 54.5%(18/33) and 87.9%(29/33) in the NPDR group, 37.3%(28/75) and 70.7%(53/75) in the NDR group, 22.9%(8/35) and 42.9%(15/35) in the control group, respectively, the proportions of superficial and deep FAZ contour abnormality in the NPDR group were significantly higher than those in the control group (both at P<0.05). With the aggravation of the condition, there were more eyes with high grades of abnormal superficial and deep FAZ contours ( χ2=9.827, 9.030; all at P<0.05). The vessel density of parafoveal DCP was (52.50[50.70, 54.80]), (50.40[48.40, 52.60]), (48.30[43.60, 51.55])%, and the vessel density of DCP was (49.90[47.70, 51.80]), (47.30[45.20, 50.10]), (45.80[41.30, 48.60])% in the control group, NDR group and NPDR group respectively, and there were statistically significant differences among the three groups ( H=21.719, 21.652; both at P<0.001), and statistically significant differences were found in pairwise comparisons among the three groups (all at P<0.05). The vessel densities of foveal SCP, foveal DCP and FD300 in the NPDR group were significantly lower than those in the control group (all at P<0.05). There was no statistically significant difference in vessel densities of parafoveal SCP and SCP found in the overall comparison among the three groups ( H=5.290, 5.534; both at P>0.05). In diabetic mellitus patients, there were negative correlations between the vessel density of parafoveal SCP and LogMAR best corrected visual acuity (BCVA), and between the vessel density of SCP and LogMAR BCVA ( rs=-0.305, -0.330; both at P<0.05), and there was a positive correlation between the superficial FAZ contour grading and LogMAR BCVA ( rs=0.353, P<0.05). Conclusions:Abnormal parafoveal DCP and DCP vessel density, as well as FAZ contour, appear in diabetic mellitus patients before the occurrence of visible fundus lesion, and the vessel density of parafoveal SCP and SCP, and superficial FAZ contour grading in diabetic mellitus patients are correlated with visual acuity.OCTA can help monitor disease progression and identify microcirculation parameters that affect visual function.

ABSTRACT

The aim of this study is to investigate the role of fibroblast growth factor 21 (FGF21) in empagliflozin (EMP) in treatment of heart failure and the related mechanisms. FGF21 knockout (FGF21 KO) and littermate wild-type (WT) mice induced by doxorubicin (Dox) were used to establish heart failure mouse model in vivo. The experiment process and animal welfare follow the regulations of Animal Ethics Committee of Hefei University of Technology strictly. The results suggest that Dox (5 mg·kg-1) induced typical heart failure symptoms in both WT and FGF21 KO mice. In WT mice, EMP (10 mg·kg-1) significantly improved Dox-induced cardiac atrophy, decreased myocardial systolic function, decreased left ventricular ejection fraction and shortened fraction; EMP treatment also significantly inhibited the increase of Dox-induced cardiotoxicity indexes (aspartate amino transferase, creatine kinase, hydroxybutyrate dehydrogenase, lactate dehydrogenase) in mice. Dox induced cardiac fibrosis, inflammation and oxidative stress were also significantly improved by EMP. However, in FGF21 KO mice, the therapeutic effects of EMP on heart failure was significantly inhibited. The results suggest that the function of EMP in treating heart failure partly depends on the presence of FGF21, and the mechanism may be related to the effect of FGF21 on improving fibrosis, inflammation and oxidative stress.

ABSTRACT

Cystic fibrosis (CF) is a rare autosomal recessive disease with only one pathogenic gene cystic fibrosis transmembrane conductance regulator (CFTR). To identify the potential pathogenic mutations in a Chinese patient with CF, we conducted Sanger sequencing on the genomic DNA of the patient and his parents and detected all 27 coding exons of CFTR and their flanking intronic regions. The patient is a compound heterozygote of c.2909G > A, p.Gly970Asp in exon 18 and c.1210-3C > G in cis with a poly-T of 5T (T5) sequence, 3 bp upstream in intron 9. The splicing effect of c.1210-3C > G was verified via minigene assay in vitro, indicating that wild-type plasmid containing c.1210-3C together with T7 sequence produced a normal transcript and partial exon 10-skipping-transcript, whereas mutant plasmid containing c.1210-3G in cis with T5 sequence caused almost all mRNA to skip exon 10. Overall, c.1210-3C > G, the newly identified pathogenic mutation in our patient, in combination with T5 sequence in cis, affects the CFTR gene splicing and produces nearly no normal transcript in vitro. Moreover, this patient carries a p.Gly970Asp mutation, thus confirming the high-frequency of this mutation in Chinese patients with CF.

ABSTRACT

With reference to the production process documented in Chinese Pharmacopoeia, this paper prepared the calibrator samples of Xiaochaihu Granules from multiple batches and established a method for fingerprint analysis and content determination that could be used to evaluate Xiaochaihu Granules available in market. Multiple batches of Chinese herbal pieces contained in Xiaochaihu Granules were collected for preparing the calibrator samples according to the process in Chinese Pharmacopoeia. Following the establishment of fingerprints for calibrator samples by UHPLC, the method for determining the contents of saikosaponin B2, saikosaponin B1, baicalin, wogonoside, baicalein, liquiritin, glycyrrhizin G2 and glycyrrhizic acid in Xiaochaihu Granules was established. The experimental results showed that the fingerprints of calibrator samples had 26 common peaks, covering the chemical compounds of main herbs Bupleuri Radix, Scutellariae Radix, Changii Radix, Glycyrrhizae Radix et Rhizoma, and Rhizoma Zingiberis Recens. The similarity of fingerprints for 47 batches of Xiaochaihu Granules from 31 companies with the calibrator sample fingerprint ranged from 0.74 to 0.99, indicating good applicability of the established fingerprint. The contents of main components baicalin, saikosaponin B2, and glycyrrhizic acid in Xiaochaihu Granules were within the ranges of 22.917-49.108 mg per bag(RSD 19%), 0.28-2.19 mg per bag(RSD 62%), and 0.897-6.541 mg per bag(RSD 41%), respectively. The quality difference in saikosaponin B2, and glycyrrhizic acid among different manufacturers was significant. The fingerprint analysis and content determination method for calibrator samples of Xiaochaihu Granules prepared according to the production process in Chinese Pharmacopoeia has been proved suitable for evaluating the quality of Xiaochaihu Granules from different manufacturers. Saikosaponin B2, glycyrrhizic acid, and liquiritin should be added as content control indicators for Xiaochaihu Granules, aiming to further improve the product quality.

ABSTRACT

Objective To reveal the incidence,mortality,and risk factors of bleeding-related perioperative cardiac arrest(POCA). Methods We carried out a single-center retrospective case-control study which enrolled all the POCA cases reported from January 2010 to September 2020 in the patient safety incident reporting system of Peking Union Medical College Hospital.For the screening of risk factors,the patients were respectively assigned into the POCA group and the control group at a ratio of 1∶3 according to the same sex,age,American Society of Anesthesiologists(ASA)physical status,and type of surgery in the same month.Potential risk factors for POCA were first selected by univariate analysis.The significant risk factors were then checked based on the clinical experience and further included in the multivariate Logistic regression model. Results Totally 16 bleeding-related POCA cases were collected from the patient safety incident reporting system among the study period,with an overall incidence of 0.36/10 000.The blood loss volume of POCA group and control group was(7 037.50±5 477.70)ml and(375.63±675.14)ml,respectively(P<0.001),and 14(87.5%)patients suffering from bleeding-related POCA died within three days after anesthesia.According to the univariate analysis,patients' body mass index[(21.79±3.57)kg/m2 vs.(24.26±3.91)kg/m2,P=0.043],hemoglobin level[(113.44±31.08)g/L vs.(131.75±19.70)g/L,P=0.039],and alanine aminotransferase level[(17.31±7.73)U/L vs.(26.91±24.73)U/L,P=0.022]were significantly lower in the POCA group than in the control group.Further Logistic regression analysis showed that smaller body mass index and lower preoperative hemoglobin level were independently associated with the occurrence of bleeding-related POCA. Conclusions Bleeding-related POCA rarely occurred but had high mortality.Adequate precautions should be taken for the patients who are to receive surgeries with high risk of intraoperative massive bleeding.Elevating preoperative hemoglobin level might decrease the incidence of bleeding-related POCA.

ABSTRACT

Objective:To investigate the drug resistance of patients with acquired immunodeficiency syndrome (AIDS) who failed antiviral therapy.Methods:A total of 156 AIDS patients with antiviral therapy failure at the Sixth People′s Hospital of Zhengzhou from October 2017 to December 2018 were selected. The human immunodeficiency virus (HIV)-1 ViroSeq? genotyping method was used for the detection of HIV resistance, and Stanford University HIV drug resistance database (http: ∥hivdb.stanford.edu/) was used for testing results comparison.Results:Among the 156 AIDS patients with antiviral therapy failure, 122(78.21%) developed drug resistance. One hundred and six (67.95%) cases were multi-resistant to nucleoside reverse transcriptase inhibitor (NRTI), among which, 104 (66.67%) were resistant to lamivudine, emtricitabine and abacavir. One hundred and eighteen (75.64%) were resistant to non-nucleoside reverse transcriptase inhibitor (NNRTI), and 118 (75.64%) were multi-resistant to efavirenz and nevirapine. And seven (4.49%) were resistant to protease inhibitor (PI). There were 16 resistant sites for NRTI, with 87 (71.31%) most frequent M184V/I mutations. There were 13 resistant sites for NNRTI, with 49 (40.16%) K103N/R mutations. There were 11 resistant sites for PI, with 49 (40.16%) A71V/T mutations. The antiviral drugs lamivudine and emtricitabine were moderately and highly resistant in 102 (83.61%) cases, efavirenz and nevirapine were moderately and highly resistant in 117 (95.90%) cases. Once drug resistance developed, these drugs were likely to be moderate or high resistance. There were 29 (23.77%), 48 (39.34%), and five (4.10%) cases were resistant to zidovudine, tenofovir and lopinavir/ritonavir, respectively. The resistance barrier of these drugs was relatively high.Conclusion:The incidence of drug resistance in patients with AIDS treatment failure is high, and multi-drug resistance is serious with various sites of drug resistance.

ABSTRACT

BACKGROUND@#Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive cancers without effective therapy. To explore potential molecular targets in ESCC, we quantified the mutation spectrum and explored the relationship between gene mutation and clinicopathological characteristics and programmed death-ligand 1 (PD-L1) expression.@*METHODS@#Between 2015 and 2019, 29 surgically resected ESCC tissues and adjacent normal tissues from the Fourth Hospital of Hebei Medical University were subjected to targeted next-generation sequencing. The expression levels of PD-L1 were detected by immunohistochemistry. Mutational signatures were extracted from the mutation count matrix by using non-negative matrix factorization. The relationship between detected genomic alterations and clinicopathological characteristics and PD-L1 expression was estimated by Spearman rank correlation analysis.@*RESULTS@#The most frequently mutated gene was TP53 (96.6%, 28/29), followed by NOTCH1 (27.6%, 8/29), EP300 (17.2%, 5/29), and KMT2C (17.2%, 5/29). The most frequently copy number amplified and deleted genes were CCND1/FGF3/FGF4/FGF19 (41.4%, 12/29) and CDKN2A/2B (10.3%, 3/29). By quantifying the contribution of the mutational signatures to the mutation spectrum, we found that the contribution of signature 1, signature 2, signature 10, signature 12, signature 13, and signature 17 was relatively high. Further analysis revealed genetic variants associated with cell cycle, chromatin modification, Notch, and Janus kinase-signal transducer and activator of transcription signaling pathways, which may be key pathways in the development and progression of ESCC. Evaluation of PD-L1 expression in samples showed that 13.8% (4/29) of samples had tumor proportion score ≥1%. 17.2% (5/29) of patients had tumor mutation burden (TMB) above 10 mut/Mb. All samples exhibited microsatellite stability. TMB was significantly associated with lymph node metastasis (r = 0.468, P = 0.010), but not significantly associated with PD-L1 expression (r = 0.246, P = 0.198). There was no significant correlation between PD-L1 expression and detected gene mutations (all P > 0.05).@*CONCLUSION@#Our research initially constructed gene mutation profile related to surgically resected ESCC in high-incidence areas to explore the mechanism underlying ESCC development and potential therapeutic targets.

ABSTRACT

OBJECTIVE@#To observe the analgesic effect of auricular point sticking therapy during the perioperative stage in the patients with partial lung resection.@*METHODS@#A total of 92 patients with partial lung resection were randomized into an auricular point group (31 cases, 1 case dropped off), the sham-auricular point group (30 cases) and a medication group (31 cases, 1 case dropped off). The routine medication for analgesia was provided in all of the three groups. In the auricular point group, 1 day before operation, the auricular point sticking therapy was applied at shenmen (TF@*RESULTS@#In 8, 16, 24, 48 h and 72 h after operation, VAS scores in the auricular point group were lower than those in the sham-auricular point group and the medication group separately (@*CONCLUSION@#Auricular point sticking therapy relieves perioperative pain, shortens analgesic time, releases anxious and depressive emotions and reduces postoperative adverse reaction in the patients with partial lung resection. The analgesic mechanism is probably related to the increase of plasma concentration of β-endorphin.

ABSTRACT

@#MicroRNAs(miRNAs)are one of the most important regulatory factors of gene expression, which involved in the growth, development, differentiation and apoptosis of various cells, tissues and organs. TRPM3 is located in human chromosome 9 and belongs to M sub-family of the transient receptor potential(TRP)channels. MiR-204 is located on TRPM3 intron 6 and participates in the regulation of post-transcriptional gene expression through cleavage or translation inhibition of target mRNAs. Studies have shown that TRPM3/miR-204 complex locus plays an important role in the occurrence and development of eye diseases such as cataract, glaucoma, corneal neovascularization, corneal wound healing, retinal diseases, optic nerve diseases and so on. In this paper, the biological function of TRPM3/miR-204, its expression and regulation in the eyes and its correlation with a variety of ophthalmic diseases are reviewed.

ABSTRACT

For rheumatoid arthritis, glucocorticoids or immunosuppressive agents are currently used in clinical treatment, but long-term use of these drugs has large side effect on humans, and immunosuppressive agents are expensive. To a certain extent, its wide application is limited. The treatment of rheumatoid arthritis with traditional Chinese medicine(TCM) has a long history and little toxic and side effect, but its specific mechanism of action needs further exploration. The process of autophagy is an active biological process in which cells themselves are stimulated by the outside world through intracellular signal transduction to maintain a stable internal environment. Its abnormality is involved in the occurrence of many diseases. At present, studies have shown that abnormal autophagy is closely related to the occurrence and development of rheumatoid arthritis, which can interfere with the pathological changes of RA pannus formation, synovial inflammation and bone destruction and affect the disease process. In recent years, many studies have found that traditional Chinese medicine and its active ingredients can affect the pathological development of rheumatoid arthritis by regulating autophagy. This article investigates the relevant literature on the intervention of rheumatoid arthritis by regulating autophagy through using TCM, with a view to providing new ideas for basic research, new drug development and clinical treatment of rheumatoid arthritis.

ABSTRACT

Objective:To study the mechanism of astragaloside Ⅳ in the treatment of ischemic stroke by means of network pharmacology. Method:The targets of astragaloside Ⅳ were predicted using Swiss Target Prediction platform, and the targets of ischemic stroke were retrieved using GeneCards, Therapeutic Target Database (TTD), Traditional Chinese Medicine Integrated Database (TCMID) and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) databases. The potential targets of astragaloside Ⅳ acting on ischemic stroke were obtained by the intersection of the targets of astragaloside Ⅳ and ischemic stroke. STRING platform was used to build protein-protein interaction (PPI) network, and eigenvalues were calculated through network topology analysis to screen core targets. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed on the related targets in DAVID database. Finally, molecular docking verification was conducted to further clarify the core targets of astragaloside Ⅳ acting on ischemic stroke. Result:The 44 common targets were obtained after the intersection of the targets of astragaloside Ⅳ and ischemic stroke. PPI network topology analysis showed that RAC-alpha serine/threonine-protein kinase (Akt1), renin (REN), epidermal growth factor receptor (EGFR), vascular endothlial growth factor A (VEGFA) and neuronal proto-oncogene tyrosine-protein kinase (SRC) were the core targets of astragaloside Ⅳ in the treatment of ischemic stroke. Enrichment analysis results of KEGG pathway showed that the pathways of astragaloside Ⅳ acting on ischemic stroke involved the neuroactive ligand-receptor interaction pathway, cGMP-PKG signaling pathway, calcium signaling pathway, Rap1 signaling pathway, PI3K/Akt signaling pathway, etc. Conclusion:Astragaloside Ⅳ may promote angiogenesis and inhibit platelet activity by acting on Akt1, REN, EGFR, VEGFA, SRC, thus improving cerebral blood flow. It can also inhibit the apoptosis of ischemic brain tissue cells and inflammation to reduce the damage of nerve function, and finally treat ischemic stroke. This study provides ideas and guidance for further exploring the mechanism of astragaloside Ⅳ in the treatment of ischemic stroke.

ABSTRACT

In traditional Chinese medicine, it is believed that the spleen is the foundation of acquired nature and the source of Qi and blood. All life activities of a person since birth depend on the water and grain essence transported by spleen and stomach. The liver helps the spleen to strengthen the movement, the liver and spleen cooperate with each other. The liver and the spleen are invigorated, so that the Qi and blood are sufficient. The external energy can nourish the limbs, muscles and fur. The Qi and blood can be supplied to the internal organs, meridians and bones, and the body can be nourished both inside and outside to strengthen the acquired foundation. Emotional dissatisfaction can lead to stagnation of liver Qi, loss of spleen Qi, failure to dredge Qi, and deficiency of spleen Qi, forming the syndrome of liver depression and spleen deficiency. Its clinical manifestations include the symptoms of liver Qi stagnation such as depression, stamina, and chest fullness, as well as symptoms of spleen deficiency such as anorexia, abdominal distension, loose stools. Xiaoyaowan is an effective classic prescription for the treatment of liver stagnation and spleen deficiency syndrome, which is based on the dosage form of Xiaoyaosan in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy. It has the effect of relieving depression, nourishing blood and invigorating spleen. In modern research, it has been found that Xiaoyaowan has good curative effect in the treatment of endocrine diseases, liver diseases, immune diseases, and neurological diseases, etc. It was praised by the famous medical scientist YE Tian-shi in the Qing Dynasty as "the holy medicine for women", with a wide range of significant curative effects gynecology. Progress has been also made in pharmacological research. In this article, we have searched and consulted the relevant literature reports of Xiaoyaowan in recent years, summarized the key directions of the pharmacological research literature, and proposed deficiencies to provide relevant basis for the in-depth study of Xiaoyao pill in the future.

ABSTRACT

Objective:To observe the regulatory effect of modified Shengmaiyin adjuvant chemotherapy on the nutritional status and immune function of children with acute lymphocyte (ALL). Method:One hundred children with ALL chemotherapy were randomly divided into observation group and control group. Both groups were given VDLD regimen as the induction therapy and CAM regimen as the early therapy. Control group was given Shengmaiyin orally, 10 mL/time, 3 times/day. Observation group was given modified Shengmaiyin orally, 1 does/day. The course of treatment for both groups was 3 months. Micro-nutrition assessment (MNA) was carried out before and after treatment, and serum total protein (TB), albumin (ALB), prealbumin (PAB), T cell CD4<sup>+</sup>, CD8<sup>+</sup>, immunoglobulin G (IgG), IgM, IgA levels were detected before and after treatment. The ratio of CD4<sup>+</sup>/CD8<sup>+</sup> was calculated. The traditional Chinese medicine (TCM) syndrome before and after treatment and the piper fatigue scale (PFS-R) and universal core scale of children's quality of life (PedsQL) were scored. The changes of white blood cells (WBC), red blood cells (RBC), hemoglobin (Hb) and platelets (PLT) were evaluated before and after treatment. Result:The nutritional status of the observation group was better than that of the control group after treatment (<italic>Z</italic>=2.018, <italic>P</italic><0.05). The observed fatigue was lighter than that of the control group (<italic>Z</italic>=2.029, <italic>P</italic><0.05). The MNA score of the observation group was higher than that of the control group (<italic>P</italic><0.01). The scores of PFS-R and deficiency of both Qi and blood were lower than those of the control group (<italic>P</italic><0.01). The CD4<sup>+ </sup>levels and CD4<sup>+</sup>/CD8<sup>+</sup> levels of TB, ALB and PAB in the observation group were higher than those in the control group (<italic>P</italic><0.01), while the CD8<sup>+</sup> was lower than the control group (<italic>P</italic><0.01). The IgM and IgA levels in the observation group were higher than those in the control group (<italic>P</italic><0.01). The RBC, Hb and PLT levels of the observation group were higher than those of the control group (<italic>P</italic><0.01). Conclusion:Modified Shengmaiyin can be used as adjuvant therapy for children with ALL chemotherapy by improving nutritional status, immune function and immune balance, reducing clinical symptoms, promoting the recovery of hematopoietic system and improving the quality of life.

ABSTRACT

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory disorder of the central nervous system predominantly targeting optic nerves and the spinal cord. The prevalence of the disease is much higher in Asia than in other parts of the world. Pain can be detected in more than 80% of NMOSD patients, with evoked pain mostly being caused by painful tonic muscle spasms and neuropathic pain as the most characteristic types. Depression is often comorbid with pain, and their comorbidity can severely influence quality of life. In recent years, studies have found considerable overlaps between the mechanisms of pain and depression; however, their association remains unclear. This article reviews the epidemiology, mechanism, evaluation and treatment of pain-depression comorbidity in NMOSD patients.

ABSTRACT

Seabuckthorn contains flavonoids, tannins, terpenoids, polysaccharides, and vitamins, which have anti-inflammation,anti-oxidation, liver protection, anti-cardiovascular disease, anti-aging, immune enhancing, anti-tumor, and anti-bacterial activities.We reviewed the papers focusing on the chemical constituents, pharmacological activities, and utilization of seabuckthorn. The quality markers(Q-markers) of seabuckthorn were predicted and analyzed based on original plant phylogeny, chemical composition correlation, traditional medicinal properties, pharmacodynamic correlation, traditional and extended efficacy, pharmacokinetics, metabolic processes, and measurable components. With this review, we aim to provide theoretical reference for the quality control and quality standard establishment of seabuckthorn, so as to promote the rational exploitation and utilization of seabuckthorn resources, and improve the healthy and sustainable development of seabuckthorn industry.

ABSTRACT

Diosgenin is widely distributed in many plants, such as Polygonatum sibiricum, Paris polyphylla, Dioscorea oppositifolia, Trigonella foenum-graecum, Costus speciosus, Tacca chantrieri, which has good anti-tumor activity and preferable effects on preventing atherosclerosis, protecting the heart, treating diabetes, etc. This review combed through the anti-tumor mechanisms of diosgenin encompassing lung, breast, gallbladder, liver, oral cavity, stomach, bladder, bone marrow, etc. Besides, it was discovered that diosgenin mainly exerts its effect by inhibiting tumor cell migration, suppressing tumor cell proliferation and growth, and inducing cell apoptosis. However, problems like low yield and bioavailability frequently exist in natural diosgenin. This review introduced methods such as structural modification, dosage form optimization and combination medication to improve the yield and anti-tumor activity of diosgenin. Via the summary of this paper, it is expected to provide theoretical basis for the rational exploitation and utilization of diosgenin.
