RESUMO

Cells not only contain membrane-bound organelles (MBOs), but also membraneless organelles (MLOs) formed by condensation of many biomacromolecules. Examples include RNA-protein granules such as nucleoli and PML nuclear bodies (PML-NBs) in the nucleus, as well as stress granules and P-bodies in the cytoplasm. Phase separation is the basic organizing principle of the form of the condensates or membraneless organelles (MLOs) of biomacromolecules including proteins and nucleic acids. In particular, liquid-liquid phase separation (LLPS) compartmentalises and concentrates biological macromolecules into liquid condensates. It has been found that phase separation of biomacromolecules requires some typical intrinsic characteristics, such as intrinsically disordered regions, modular domains and multivalent interactions. The phase separation of biomacromolecules plays a key role in many important cell activities. In recent years, the phase separation of biomacromolecules phase has become a focus of research in gene transcriptional regulation. Transcriptional regulatory elements such as RNA polymerases, transcription factors (TFs), and super enhancers (SEs) all play important roles through phase separation. Our group has previously reported for the first time that long-term inactivation or absence of assembly factors leads to the formation of condensates of RNA polymerase II (RNAPII) subunits in the cytoplasm, and this process is reversible, suggesting a novel regulatory model of eukaryotic transcription machinery. The phase separation of biomacromolecules provides a biophysical understanding for the rapid transmission of transcriptional signals by a large number of TFs. Moreover, phase separation during transcriptional regulation is closely related to the occurrence of cancer. For example, the activation of oncogenes is usually associated with the formation of phase separation condensates at the SEs. In this review, the intrinsic characteristics of the formation of biomacromolecules phase separation and the important role of phase separation in transcriptional regulation are reviewed, which will provide reference for understanding basic cell activities and gene regulation in cancer.

RESUMO

This study aims to establish the ultra-performance liquid chromatography(UPLC) fingerprint and multi-indicator quantitative analysis method for Schisandrae Sphenantherae Fructus(SSF) and to screen out the potential quality markers(Q-markers) of hepatoprotection based on network pharmacology. The similarity analysis was performed using the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System, which showed that the similarity of the fingerprints of 15 samples from different regions ranged from 0.981 to 0.998. Eighteen common components were identified, from which 3 differential components were selected by cluster analysis and principal component analysis. The "component-target-pathway" network was built to predict the core components related to the hepatoprotective effects. Fourteen core components were screened by network pharmacology. They acted on the targets such as AKT1, CCND1, CYP1A1, CYP3A4, MAPK1, MAPK3, NOS2, NQO1, and PTGS2 to regulate the signaling pathways of lipid metabolism and atherosclerosis, hepatitis B, interleukin-17, and tumor necrosis factor. Considering the chemical measurability, characteristics, and validity, schisantherin A, anwulignan, and schisandrin A were identified as the Q-markers. The content of schisantherin A, anwulignan, and schisandrin A in the test samples were 0.20%-0.57%, 0.13%-0.33%, and 0.42%-0.70%, respectively. Combining the fingerprint, network pharmacology, and content determination, this study predicted that schisantherin A, anwulignan, and schisandrin A were the Q-markers for the hepatoprotective effect of SSF. The results can provide reference for improving the quality evaluation standard and exploring the hepatoprotective mechanism of SSF.

RESUMO

Gastric cancer (GC) is a serious threat to human health and an important cause of cancer-related death. Herein, we evaluated the influence of transmembrane protein 158 (TMEM158) on GC cell growth. According to Genomic Spatial Event (GSE) and The Cancer Genome Atlas (TCGA) databases, TMEM158 content is amplified in GC tissues. The diagnostic value of TMEM158 expression in GC is huge. GC sufferers with high expression of TMEM158 were associated with poor overall survival. In addition, TMEM158 content was increased in GC cells. TMEM158 promoted GC cell proliferation by modulating the PI3K/Akt signaling pathway. Lack of TMEM158 reduced GC tumor growth. Collectively, TMEM158 accelerated GC cell proliferation by modulating the PI3K/Akt signaling pathway, making it a prospective biomarker for survival in GC patients.

RESUMO

@#Head and neck squamous cell carcinoma (HNSCC) is a common malignant tumor that seriously threatens human health and life. With increasing studies on the mechanism of tumor immune escape, programmed death receptor 1 (PD-1) and programmed death ligand receptor 1 (PD-L1) have been proven to be involved in tumor immune escape. The primary mechanism is that PD-1 recruits protein tyrosine phosphatase (SHP-2) to dephosphorylate downstream tyrosine kinase (SyK) and phosphatidylinositol 3-kinase (PI3K), thereby inhibiting downstream protein kinase B (AKT), extracellular regulated protein kinases (ERK) and other important signaling pathways, ultimately inhibiting T cell activation. In recent years, PD-1/PD-L1 inhibitors have become popular immunotherapies. Pembrolizumab and nivolumab have been approved for HNSCC patients by the U.S. Food and Drug Administration. Both durvalumab and atezolizumab are still in clinical trials, and published data show that both have certain safety and efficacy but still need much clinical data to support them. Meanwhile, the combination of PD-1/PD-L1 inhibitors with radiotherapy, chemotherapy and immunotherapy is still controversial in terms of clinical efficacy and adverse events, and further research is needed. However, serious immune-related adverse reactions limit the clinical application of PD-1/PD-L1 inhibitors, despite promising curative effects. Therefore, developing novel inhibitors and investigating stable and effective biomarkers and upstream and downstream signaling mechanisms are urgent issues.

RESUMO

Magnoliae Officinalis Cortex(Houpo) can treat peptic ulcer disease(PUD), the mechanism of which remains unclear. In this study, network pharmacology and molecular docking were employed to predict the mechanism of Houpo in the treatment of PUD. Through literature review and TCMSP screening, 15 main active ingredients were obtained. The SwissTargetPrediction database was used to predict the potential targets of the ingredients, and Therapeutic Target Database(TTD), DrugBank, and Human Phenotype Ontology(HPO) to screen the disease-related targets. A total of 49 potential targets were obtained by the intersection of active ingre-dients-related targets and disease-related targets. Cytoscape 3.6.1 was employed to construct the protein-protein interaction network for the targets with high confidence(score>0.700) screened out by STRING. The DAVID database was used for GO and KEGG pathway enrichment of potential targets. GO enrichment analysis showed that the treatment mechanism was mostly related to nuclear receptor activity, ligand-activated transcription factor activity, and G protein-coupled acetylcholine receptor activity. KEGG enrichment analysis found that Houpo could regulate material metabolism, endocrine system, p53 signaling pathway, and PPAR signaling pathway. Molecu-lar docking verified that all 15 ingredients had good binding activities with key targets(CHRM1, CHRM2, FABP1, mTOR, and STAT3). The results mean that Houpo can treat PUD by participating in cell metabolism, inhibiting inflammatory cytokines, and regulating cell proliferation and apoptosis.

RESUMO

Banxia Houpo Tang is widely used in modern clinics with definite curative effect. It is one of the classic famous prescriptions in the Catalogue of Ancient Classic Famous Recipes(First Batch) published by the State Administration of Traditional Chinese Medicine(TCM) in 2018. Using bibliometrics methods,collect relevant literatures of Banxia Houpo Tang in ancient medical books,analyze and verify the origin,historical evolution,composition,prescription,function,dosage,artillery,preparation method and decoction method of prescription. A total of 259 related ancient literature data were obtained,involving 107 TCM books. The inductive analysis found that Banxia Houpo Tang originated from ZHANG Zhong-jing's Synopsis of the Golden Chamberin the Han dynasty and consisted of the five flavors of Pinelliae Rhizoma,Magnoliae Officinalis Cortex,Poria,Perillae Folium and Zingiberis Rhizoma Recens. Houpo Tang,Qiqi Tang,Siqi Tang,Daqiqi Tang and other synonyms have appeared in the records of medical records of all dynasties. The prescription composition,preparation method and decoction method are used by later generations of medical practitioners. The analysis of related prescriptions is also rarely disputed. The dosage of drugs used in Banxia Houpo Tang can be calculated as 1g or 3 g. The drug processing method is different from the original one. Pinelliae Rhizoma should choose Pinelliae Rhizoma Praeparatum Cum Zingibere et Alumine and Magnoliae Officinalis Cortex as "Jianghoupu". The rest of the drug processing methods respect the 2015 edition of Chinese Pharmacopoeia. The cardiology of its treatment has also been extended and expanded. In addition to the symptoms of "burning in the pharynx" recorded by the original party,this side can also be used for heart diseases such as heartache,chest tightness,sorrow,vomiting,choking noisy and other spleen and stomach disease syndrome and spermatorrhea,turbidity,scorching and other lower coke disease syndrome.

RESUMO

Pinelliae Rhizoma is a toxic traditional Chinese medicine, and its dose differs greatly between at ancient and modern times, so that it is difficult for researchers to determine its dosage during research and development of famous classical formulas. According to the literature research, it is found that the dose of Pinelliae Rhizoma in famous classical formulas has undergone a process from large to small. Based on the principle of " following the classic and conforming to pharmacopoeia" , and in combination with the modern actual situation, the reasonable dose of Pinelliae Rhizoma in the 17 formulas from the Catalogue of Ancient Famous Classical Formulas (The First Batch) is determined. According to the records of the original book, the evolution of past dynasties and the consideration of the current clinical application, dosage regimen and administration methods of the 17 famous classical formulas and so on, the authors suggested that the dosages of Pinelliae Rhizoma in Banxia Houpotang and Maimendong Tang are 15.0 g, its dosages in Wendantang and Sangbaipi Tang are 6.0 g, dosages of Pinelliae Rhizoma in Xuanfu Daizhe Tang, Zhuye Shigaotang, Banxia Xiexintang, Gancao Xiexintang, Huangliantang, Gualou Xiebai Banxiatang, Houpo Mahuangtang and Jinshui Liujunjian are 7.5 g, the dosages of Pinelliae Rhizoma in Zhurutang, Shengyang Yiweitang and Yangweitang are 6.7, 4.5, 5.0 g, respectively, dosages of Pinelliae Rhizoma in Banxia Baizhu Tianma Tang and Huopo Xialing Tang are 5.6 g.

RESUMO

Xiaoshuan Tongluo formula is effective in treating mental retardation and speech astringency caused by cerebral thrombosis, but its mechanism remains unclear. In this investigation, by collecting the chemical constituents from Xiaoshuan Tongluo formula and the targets related to stroke, we obtained 1 251 constituents from the formula and 10 drug targets related with stroke. We established 18 prediction models of compound-target interaction for 10 stroke-related targets, using molecular docking method and machine learning methods includes Naive Bayesian and recursive partitioning based on the input of molecular fingerprints and molecular descriptors. Using these models, we predicted the active chemical constituents from Xiaoshuan Tongluo formula and their drug targets, 153 potential active constituents were discovered, 22 among them could interact with at least two drug targets related with stroke. On this basis, the chemical constituent-target network was constructed using network construction software, and then the important metabolic pathways of the targets were identified by using Gene-Ontology (GO) enrichment analysis, such as blood coagulation, positive regulation of angiogenesis, positive regulation of ion transport and so on. On this basis, a target-pathway network was constructed. In conclusion, using machine learning, molecular docking, virtual screening, data mining and network construction, this study explored and partially revealed the active chemical constituents and chemical constituent-target-pathway network action mechanism of Xiaoshuan Tongluo formula against stroke, which will provide important information for its further study.

RESUMO

There are 17 formulas containing Pinelliae Rhizoma in the Catalogue of Ancient Famous Classical Formulas (the First Batch), most of which are only labeled with " washing with decoction" or without any processing method, which is inconsistent with the current use requirements and brings confusion to research and development of related famous classical formulas. Through combing the records of famous classical formulas in the original book, contemporary works and later works, the usage of processed products of Pinelliae Rhizoma in the evolution of past dynasties was contrasted, and the efficacy, indications and compatibility significance of different formulas were analyzed, according to the principle of " respecting the ancient but not confining the ancient" , the authors suggested that the 17 famous classical formulas should use the processed products of Pinelliae Rhizoma in the 2015 edition of Chinese Pharmacopoeia, including Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Pinelliae Rhizoma Praeparatum cum Alumine. Among them, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine should be used in Banxia Xiexintang, Gancao Xiexintang, Huangliantang, Xuanfu Daizhe Tang, Zhuye Shigaotang, Banxia Houpotang, Maimendong Tang, Gualou Xiebai Banxiatang, Wendantang, Zhurutang, Jinshui Liujun Jian and Yangweitang, Pinelliae Rhizoma Praeparatum should be used in Shengyang Yiweitang, Houpo Mahuangtang, Banxia Baizhu Tianma Tang and Huopo Xialing Tang, and Pinelliae Rhizoma Praeparatum cum Alumine should be used in Sangbaipi Tang.

RESUMO

Objective@# To investigate the etiology, diagnosis and treatment principles of inherited permanent tooth embryo necrosis caused by alveolar bone resorption due to severe periapical periodontitis of deciduous teeth, in order to provide a reference for clinical diagnosis and treatment@*Methods@#The clinical data and related literature of a rare case of permanent tooth embryo necrosis were analyzed retrospectively.@*Results @#This case was a 5-year-old girl. Physical examination and X-ray examination revealed chronic periapical inflammation in 75. X-ray showed that the periodontal bone of tooth 75 was extensively destroyed; additionally, the permanent tooth germ of tooth 35 was incomplete and the development was delayed compared to that of tooth 45 because of severe periapical periodontitis in the primary teeth. The initial diagnosis was that-- the embryo of tooth 35 stopped developing due to inflammation and was necrotic after tooth 75 was extracted. The postoperative pathological examination report showed that most bone around the embryos of tooth 35 was sequestrated. Through literature review and analysis, it was found that the degree of periapical lesions in the primary teeth and the developmental stage of the tooth embryo have a great impact on the formation of permanent tooth embryos. Conservative methods such as root canal therapy are usually adopted as treatment. Permanent tooth embryo necrosis caused by periapical periodontitis of deciduous teeth is rare in the clinic, so it is necessary to judge the degree of inflammatory infiltration and of tooth embryo damage as soon as possible according to the clinical symptoms and imaging manifestations; and to make a correct treatment plan.@*Conclusion@#There are no objective and clear diagnostic and treatment criteria for the clinical diagnosis of the pathological state of permanent tooth embryo, thus, methods such as etiology elimination and follow-up observation are usually adopted for abnormal permanent tooth embryo development. Future research should focus on prevention and finding addtional effective methods for diagnosis and treatment.

RESUMO

Objective To identify whether rtL180M+A186T+M204V mutation is a novel entecavir (ETV)-resistant mutation. Methods A total of 12 708 patients in the Fifth Medical Center of Chinese PLA General Hospital from July 2011 to July 2016 were enrolled in this study. Drug resistance mutation in reverse transcriptase region (RT) were analyzed by direct sequencing and verified by clonal sequencing if rtL180M+A186T+M204V has been detected (≥20 clones/sample); 1.1-mer HBV replicons harboring wild-type or mutant RT gene were constructed respectively and transfected into HepG2 cells for phenotypic analysis. Results ETV experienced patients were detected in 4047 of total patients. Among these patients, classical ETV-resistant mutation of HBV and rtL180M+A186T+M204V mutation were detected in 795(19.64%) and 7(0.17%), respectively. The rtL180M+A186T+M204V mutant was consistent with the features of ETV-resistant mutation: all the rtA186T-positive patients had a history of lamivudine exposure prior to ETV treatment; the emergence of the mutations was associated with virological breakthrough or inadequate virological response to ETV; phenotypic analysis showed that patient-derived rtL180M+A186T+M204V mutant exhibited 13.3% replication capacity and 210.2-fold decreased susceptibility to ETV compared to the wild-type strain, while the mutant remained sensitive to tenofovir (TDF). Conclusions rtL180M+A186T+M204V as a novel ETV-resistance mutation has a low clinical detection rate, which is related to the markedly reduced replication capacity of the mutant. TDF-based rescue therapy should be considered for patients harboring rtL180M+A186T+M204V mutation in clinical practice.

RESUMO

ED is a common male disease, often caused by neurological, vascular or psychological factors, and the diagnostic methods for ED vary widely. The nocturnal penile tumescence test (NPT) by RigiScan is an objective assessment method used mainly to detect ED and has gained a wide clinical application in recent years. This review focuses on the application value of the six RigiScan parameters in the diagnosis of ED, namely, the number of erections, total erection time, event rigidity of tip/base, event tumescence of tip/base, tumescence activated unit and rigidity activated unit, aiming to provide some help to clinicians and researchers with the application of NPT.

RESUMO

This study aimed to evaluate whether adding a vacuum erection device (VED) to regular use of Tadalafil could achieve better penile rehabilitation following posterior urethroplasty for pelvic fracture-related urethral injury (PFUI). Altogether, 78 PFUI patients with erectile dysfunction (ED) after primary posterior urethroplasty were enrolled and divided into two treatment groups: VED combined with Tadalafil (Group 1, n = 36) and Tadalafil only (Group 2, n = 42). Changes in penile length, testosterone level, International Index of Erectile Function-5 (IIEF-5) questionnaire, Quality of Erection Questionnaire (QEQ), and nocturnal penile tumescence (NPT) testing were used to assess erectile function before and after 6 months of ED treatment. Results showed that the addition of VED to regular use of Tadalafil preserved more penile length statistically (0.4 ± 0.9 vs -0.8 ± 0.7 cm, P < 0.01). IIEF-5 score and QEQ score in Group 1 were higher than Group 2 (both P < 0.05). After treatment, 21/36 (58.3%) Group 1 patients and 19/42 (45.2%) Group 2 patients could complete vaginal penetration. Group 1 patients also had markedly improved testosterone levels (P = 0.01). Unexpectedly, there was no significant difference in NPT testing between two therapies. For PFUI patients with ED after posterior urethroplasty, the addition of VED to regular use of Tadalafil could significantly improve their conditions - improving erection and increasing penile length - thus increasing patient satisfaction and confidence in penile rehabilitation.

RESUMO

Non-alcoholic fatty liver disease (NAFLD) is a common liver disease and it represents the hepatic manifestation of metabolic syndrome, which includes type 2 diabetes mellitus (T2DM), dyslipidemia, central obesity and hypertension. Glucagon-like peptide-1 (GLP-1) analogues and dipeptidyl peptidase-4 (DPP-4) inhibitors were widely used to treat T2DM. These agents improve glycemic control, promote weight loss and improve lipid metabolism. Recent studies have demonstrated that the GLP-1 receptor (GLP-1R) is present and functional in human and rat hepatocytes. In this review, we present data from animal researches and human clinical studies that showed GLP-1 analogues and DPP-4 inhibitors can decrease hepatic triglyceride (TG) content and improve hepatic steatosis, although some effects could be a result of improvements in metabolic parameters. Multiple hepatocyte signal transduction pathways and mRNA from key enzymes in fatty acid metabolism appear to be activated by GLP-1 and its analogues. Thus, the data support the need for more rigorous prospective clinical trials to further investigate the potential of incretin therapies to treat patients with NAFLD.

RESUMO

Aromatic traditional Chinese medicines have a long history in China, with wide varieties. Volatile oils are active ingredients extracted from aromatic herbal medicines, which usually contain tens or hundreds of ingredients, with many biological activities. Therefore, volatile oils are often used in combined prescriptions and made into various efficient preparations for oral administration or external use. Based on the sources from the database of Newly Edited National Chinese Traditional Patent Medicines (the second edition), the author selected 266 Chinese patent medicines containing volatile oils in this paper, and then established an information sheet covering such items as name, dosage, dosage form, specification and usage, and main functions. Subsequently, on the basis of the multidisciplinary knowledge of pharmaceutics, traditional Chinese pharmacology and basic theory of traditional Chinese medicine, efforts were also made in the statistics of the dosage form and usage, variety of volatile oils and main functions, as well as the status analysis on volatile oils in terms of the dosage form development, prescription development, drug instruction and quality control, in order to lay a foundation for the further exploration of the market development situations of volatile oils and the future development orientation.
