RESUMEN
Diagnosis of intracranial tuberculoma remains a challenge due to its rarity, non-specific clinical presentation, and radiological findings. Herein, we describe a case of intracranial tuberculomas in a male diabetic patient who presented headache and vomiting on admission. Neuroimaging findings indicated multiple ring contrast-enhanced lesions with extensive perilesional edema. However, a cerebrospinal fluid (CSF) examination was normal. When a biopsy of brain lesions was performed, pathological characteristics of tuberculosis were absent and acid-fast staining was negative. A tuberculosis diagnosis was subsequently obtained from an Xpert MTB/RIF Ultra assay of formalin-fixed paraffin-embedded brain tissue. The patient was treated with an optimized anti-tuberculosis regimen which included high-dose intravenous administration of rifampicin and isoniazid, and oral administration of linezolid. The patient recovered well and exhibited marked clinical improvement. This case report demonstrates that when CSF analysis does not indicate the presence of intracranial tuberculomas, analysis of formalin-fixed paraffin-embedded brain tissue specimens with the Xpert MTB/RIF Ultra assay may be able to confirm a diagnosis. Furthermore, a high dose of rifampicin and isoniazid plus linezolid may improve patient outcome.
RESUMEN
Tendon-bone healing is a complex biological process. Multiple signaling pathways are involved in tendon-bone healing, including transforming growth factor-β signaling pathway, bone morphogenetic protein signaling pathway, Wnt signaling pathway, fibroblast growth factor signaling pathway and nuclear transcription factor-κB signaling pathway. This paper summarizes the research status of traditional Chinese medicine regulating related signaling pathways to promote tendon-bone healing. It is found that a variety of traditional Chinese medicine monomers or herbal extracts (such as baicalein, icariin, total flavonoids of Drynaria fortunei, parthenolide, total saponins of Panax notoginseng, etc.) and traditional Chinese medicine compounds (such as Taohong siwu decoction, Liuwei dihuang pill, Xujin jiegu liquid, etc.) can promote bone formation, anti-inflammatory, anti-oxidation, by regulating the above signaling pathways, thereby effectively promoting tendon-bone healing.
RESUMEN
The occurrence of malignant tumors is closely related to the ministerial fire. The variant ministerial fire is the fundamental factor of the formation of cancer toxin, and ministerial fire dislocation and hyperactivity are the basis for the generation of variant ministerial fire. When the ministerial fire cannot keep its position or moves without restraint, burning and exuberant, the variant ministerial fire comes out. Under the guidance of the theory of ministerial fire, the basic treatment methods to differentiate and treat malignant tumors are the direct repulsion of variant ministerial fire, and the regulation of dislocated and hyperactive ministerial fire. The method of clearing heat and resolving toxins is often used, taking a large amounts of bitter and cold herbs to reduce variant ministerial fire. For ministerial fire dislocation, ministerial fire depletion, true yang insufficiency, and the ministerial fire failing to rely on, it is common to have symptoms of upper heat and lower cold, for which the treatment method is to benefit the source of the fire, and Modified Yinhuo Decoction (引火汤加减) is commonly used. For insufficient true yin and lack of support for ministerial fire, it is suggested to nourish kidney essence, and the medicinals of enriching yin and boosting kidney are commonly used. In terms of ministerial fire hyperactivity, the treatment method should be nourishing the heart and calming the mind, and Jiaotai Pills (交泰丸) is often used to clear heart and clam the mind, and return fire to its origin. At the same time, methods such as regulating qi, resolving phlegm, clearing fire, and dispelling stasis are used to clear away tangible pathogens, so that the ministerial fire acts in a controlled manner and keeps its position and destiny.

RESUMEN
OBJECTIVE: To evaluate the efficacy and safety of acupuncture and moxibustion therapy (AMT) for cancer-related psychological symptoms (CRPS) of insomnia, depression and anxiety. METHODS: Seven databases were searched for randomized controlled trials (RCT) comparing AMT to routine care or conventional drug for alleviating CRPS of insomnia, depression, and anxiety before April 2020. Two independent reviewers performed the data extraction and assessed the risk of bias. RESULTS: A total of 30 RCTs involving 2483 cancer patients were enrolled. The pooled analysis indicated that the treatment group was significantly better than the control group in improving the depression effective rate [= 1.29, 95% (1.12, 1.49), 0.0004], the quality of life (QOL) [1.11, 95% (0.80, 1.42), 0.000 01], and reducing Self-rating Anxiety Scale (SAS) [ï¹£7.75, 95% (ï¹£10.44, ï¹£5.05), 0.000 01]. But there was no statistically significant difference between two groups in improving the insomnia effective rate [= 1.18, 95% (0.93, 1.51), 0.18]. The subgroup analysis showed the effectiveness of different intervention on CRPS. Compared with routine care, AMT helps relieve CRPS better evaluated by Pittsburgh Sleep Quality Index (PSQI), Hamilton Depression Scale (HAMD), and Self-rating Depression Scale (SDS), and depression effective rate. Compared with conventional drug, AMT performs better evaluated by SDS, depression effective rate and QOL. Moreover, the conventional drug showed higher treatment efficacy on improving insomnia effective rate compared with AMT. Compared to conventional drug, AMT plus conventional drug resulted in a significant reduction on CRPS such as PSQI, HAMD, SDS, and SAS, and also had a meaningful improvement on insomnia effective rate, depression effective rate and QOL. Fewer published reports were found on the adverse events of AMT than the conventional drug. CONCLUSION: The results suggested that AMT might be effective in improving CPRI; however, a definite conclusion could not be drawn because the quality of trials are low. Further large-scale and high-quality RCTs to verify the efficacy and safety of AMT on CRPS are still warranted.

RESUMEN
Epigenetic therapies that cause genome-wide epigenetic alterations, could trigger local interplay between different histone marks, leading to a switch of transcriptional outcome and therapeutic responses of epigenetic treatment. However, in human cancers with diverse oncogenic activation, how oncogenic pathways cooperate with epigenetic modifiers to regulate the histone mark interplay is poorly understood. We herein discover that the hedgehog (Hh) pathway reprograms the histone methylation landscape in breast cancer, especially in triple-negative breast cancer (TNBC). This facilitates the histone acetylation caused by histone deacetylase (HDAC) inhibitors and gives rise to new therapeutic vulnerability of combination therapies. Specifically, overexpression of zinc finger protein of the cerebellum 1 (ZIC1) in breast cancer promotes Hh activation, facilitating the switch of H3K27 methylation (H3K27me) to acetylation (H3K27ac). The mutually exclusive relationship of H3K27me and H3K27ac allows their functional interplay at oncogenic gene locus and switches therapeutic outcomes. Using multiple in vivo breast cancer models including patient-derived TNBC xenograft, we show that Hh signaling-orchestrated H3K27me and H3K27ac interplay tailors combination epigenetic drugs in treating breast cancer. Together, this study reveals the new role of Hh signaling-regulated histone modifications interplay in responding to HDAC inhibitors and suggests new epigenetically-targeted therapeutic solutions for treating TNBC.
RESUMEN
ObjectiveTo observe the effect of the Fangfeng Tongshengsan on post-chemoembolization syndrome with primary liver cancer or postoperative liver metastases of colorectal cancer. MethodSeventy-two patients suffered from post-chemoembolization syndrome after transcatheter hepatic arterial chemoembolization were randomly divided into 2 groups, including a Fangfeng Tongshengsan group and a control group, with 36 patients in each group. The patients in Fangfeng Tongshengsan group orally took the decoction for consecutive 7 d. The patients in the control group were physically cooled down with alcohol rub bath and ice pack for consecutive 7 d. Furthermore, the difference of fever, Karnofsky performance status (KPS), pain in the liver region, nausea vomiting, constipation, and liver function between these two groups were observed. ResultCompared with the control group, Fangfeng Tongshengsan significantly relieved fever, reduced the body temperature (P<0.05), and shortened the duration of fever (P<0.05), indicating that Fangfeng Tongshengsan remarkably improved the KPS (P<0.05). Meanwhile, Fangfeng Tongshengsan obviously alleviated nausea, vomiting, and constipation status and shortened the duration time compared with the control group (P<0.05). In addition, the parameters of liver function including alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), and total bilirubin (TBIL) were significantly decreased in the Fangfeng Tongshengsan group (P<0.05), which indicated that Fangfeng Tongshengsan alleviated liver dysfunction of patients with post-chemoembolization syndrome. ConclusionFangfeng Tongshengsan can be used to treat post-chemoembolization syndrome with primary liver cancer and postoperative liver metastases of colorectal cancer.
RESUMEN
BACKGROUND: Specific tumor markers have yet to be identified in rectal cancer. This study aims to identify a novel genetic signature in rectal cancer to provide clues for survival and immunotherapy. METHODS: DEGs were obtained from two GEO datasets of rectal cancer. By using data from TCGA and GSE133057, two cohorts of rectal cancer were applied to establish and evaluate the signature. A nomogram was constructed for training and validation. We integrated the risk-score with clinicopathological features and assessed its interplay with immune cells and molecules. Finally, our study performed functional annotations, gene-targeted miRNAs, and single-cell analysis. RESULTS: A total of 468 DEGs were identified, and a signature consisting of 5 genes (CLIC5, ENTPD8, PACSIN3, HGD, and GNG7) was selected to calculate the risk-score. The model exhibited high performance in time-dependent ROC and a nomogram. Further results showed that overall survival was significantly worse in the high-risk group. As an independent prognostic factor, the risk-score was associated with vascular invasion. There was a dramatic difference in nonregulatory CD4+ and CD8+ T cells between the high and low-risk groups, and the 5 genes were correlated with immune inhibitors. There was a considerable difference in autophagy, immune, cell cycle, infection, and apoptosis-associated terms and pathways in GO and KEGG. The functional states of differentiation, apoptosis, and quiescence were closely related to the 5-gene signature in single-cell analysis. CONCLUSION: Our results suggest that the signature could serve as a novel prognostic biomarker in rectal cancer, which might benefit decision-making regarding immunotherapy.

RESUMEN
Osteoarthritis (OA) is a common chronic degenerative disease, and its condition tends to worsen with age. The pathogenesis of OA is complex, and many risk factors can lead to the occurrence of OA. Iron is one of the essential trace elements in the body, and its metabolic balance is extremely important to human health. Iron overload is closely related to the occurrence and development of OA. Excessive iron deposition in joint tissue can easily lead to lesions of articular cartilage and synovium, as well as affect subchondral bone reconstruction and lead to the occurrence of OA. The author reviewed the relevant research literature in recent years, and reviewed the mechanism of iron overload in the occurrence and development of OA, in order to provide new ideas and directions for the research and diagnosis and treatment of OA.
RESUMEN
The development of artificial intelligence is becoming more and more mature, and has penetrated into every field of clinical trials. Artificial intelligence has brought new development opportunities for clinical trials. However, the application of artificial intelligence in clinical trials is still in the exploratory stage, facing many ethical issues, including trial risk caused by data quality, privacy protection caused by data regulation, and contradiction between data authorization and informed consent. We should precisely position the realizable application of artificial intelligence in clinical trials, understand its practical ethical issues, and formulate corresponding coping strategies to ensure the maximum improvement of the whole process performance of clinical trials, including strengthening data quality management and reducing clinical trial risks; optimizing data monitoring mechanisms to ensure data security and privacy; building a data authorization platform and improving judicial protection of informed consent, etc.
RESUMEN
Given the highly variable clinical phenotype of Coronavirus disease 2019 (COVID-19), a deeper analysis of the host genetic contribution to severe COVID-19 is important to improve our understanding of underlying disease mechanisms. Here, we describe an extended GWAS meta-analysis of a well-characterized cohort of 3,260 COVID-19 patients with respiratory failure and 12,483 population controls from Italy, Spain, Norway and Germany/Austria, including stratified analyses based on age, sex and disease severity, as well as targeted analyses of chromosome Y haplotypes, the human leukocyte antigen (HLA) region and the SARS-CoV-2 peptidome. By inversion imputation, we traced a reported association at 17q21.31 to a highly pleiotropic [~]0.9-Mb inversion polymorphism and characterized the potential effects of the inversion in detail. Our data, together with the 5th release of summary statistics from the COVID-19 Host Genetics Initiative, also identified a new locus at 19q13.33, including NAPSA, a gene which is expressed primarily in alveolar cells responsible for gas exchange in the lung.
