The gut microbiota offers numerous benefits to the human body, including the promotion of nutrient absorption, participation in metabolic processes, and enhancement of immune function. Recent studies have introduced the concept of the gut-organ axis, which encompasses interactions such as the gut-brain axis, gut-liver axis, and gut-lung axis. This concept underscores the complex interplay between gut microbiota and various organs and tissues, including the brain, heart, lungs, liver, kidneys, muscles, and bones. Growing evidence indicates that gut microbiota can influence the onset and progression of multi-organ system diseases through their effects on the gut-organ axis. Traditional Chinese medicine has demonstrated significant efficacy in regulating the gastrointestinal system, leveraging its unique advantages. Considerable advancements have been made in understanding the role of gut microbiota and the gut-organ axis within the mechanisms of action of traditional Chinese medicine. This review aims to elucidate the roles of gut microbiota and the gut-organ axis in human health, explore the potential connections between traditional Chinese medicine and gut microbiota, and examine the therapeutic effects of traditional Chinese medicine on the microbiota-gut-organ axis. Furthermore, the review addresses the limitations and challenges present in current research while proposing potential directions for future investigations in this area.

Human induced pluripotent stem (iPS) cells are remarkably similar to embryonic stem (ES) cells, but recent reports indicate that there may be important differences between them. We carried out a systematic comparison of human iPS cells generated from hepatocytes (representative of endoderm), skin fibroblasts (mesoderm) and melanocytes (ectoderm). All low-passage iPS cells analysed retain a transcriptional memory of the original cells. The persistent expression of somatic genes can be partially explained by incomplete promoter DNA methylation. This epigenetic mechanism underlies a robust form of memory that can be found in iPS cells generated by multiple laboratories using different methods, including RNA transfection. Incompletely silenced genes tend to be isolated from other genes that are repressed during reprogramming, indicating that recruitment of the silencing machinery may be inefficient at isolated genes. Knockdown of the incompletely reprogrammed gene C9orf64 (chromosome 9 open reading frame 64) reduces the efficiency of human iPS cell generation, indicating that somatic memory genes may be functionally relevant during reprogramming. A systematic comparison shows that differential DNA methylation accounts for some of the differences in somatic gene expression between induced pluripotent stem cells (iPSCs) and embryonic stem cells. The somatic genes that have persistent expression in iPSCs tend to be isolated from other genes that undergo silencing during reprogramming. This may explain the observed delay in recruitment of the DNA methylation machinery and in the genes being silenced.

Natural graphite has a large electrical conductivity in plane direction, hundreds times of that in vertical direction. Regulating graphite flakes perpendicular to the plane will improve the performance of the sensor. As a non-connected method, magnetic field-assisted orientation can be no-additives. However, some studies believe that diamagnetic materials are non-magnetic, and must be doped by ferromagnetic materials before oriented by a magnetic field. Here, original graphite flakes were vertically oriented by a low magnetic field during the electrode preparation to increase effective surface area. The performance of electrode was enhanced in both potassium ferricyanide/potassium ferrocyanide probe system and detection of hydroquinone (HQ) and catechol (CC). For HQ and CC detection, the sensitivities of vertically oriented graphite flakes electrode are 5.05 times and 6.35 times higher than that of graphite flakes without magnetic field, respectively. This magnetic alignment technology could construct other electrode materials for electrochemical sensors.

The impact of HIV-1 subtype (CRF01_(A)E and non-CRF01_(A)E) on HIV-1 DNA levels in HIV-1 chronically infected patients with suppressive antiretroviral therapy (ART) remains poorly understood. To evaluate the correlation of HIV-1 subtype with DNA level, and identify baseline predictors of HIV-1 DNA decay. ART-naïve HIV-1-infected patients from two large multi-center studies in China were classified into CRF01_(A)E and non-CRF01_(A)E subtype groups. Peripheral blood samples were collected at baseline and week 12, 24, 48 and 96 after ART initiation and total HIV-1 DNA levels were quantified by real-time PCR. HIV-1 DNA levels at week 96 were categorized into high, moderate, and low levels, reflecting HIV-1 DNA [greater than or equai to] 3, 2-3, [less than or equai to] 2 log.sub.10 copies/10.sup.6 PBMCs, respectively, and the corresponding proportion of CRF01_(A)E and non-CRF01_(A)E subtype were compared. The baseline predictors of low HIV-1 total DNA levels ([less than or equai to] 2 log.sub.10 copies/10.sup.6 PBMCs) at week 96 were evaluated using a logistic regression model. Compared to the non-CRF01_(A)E subtypes (n = 185), patients with CRF01_(A)E subtype (n = 188) harboured a higher level of HIV-1 DNA (median: 3.19 vs. 2.95 log.sub.10 copies/10.sup.6 PBMCs, P < 0.001) prior to treatment. After 96 weeks of ART, HIV-1 DNA levels remained higher in the CRF01_(A)E subtype group (median: 2.63 vs. 2.39 log.sub.10 copies/10.sup.6 PBMCs, P = 0.002). There was no significant difference in the proportion of patients achieving high (22.3% vs. 14.6%, P = 0.054), moderate (59.6% vs. 60.5%, P = 0.849) and low levels (18.1% vs 24.9%, P = 0.111) between CRF01_(A)E and non-CRF01_(A)E groups. In the multivariable analysis, baseline HIV-1 DNA level and CD4.sup.+ T cell count but not the subtype were independent risk factors for achieving HIV-1 DNA level [less than or equai to] 2 log.sub.10 copies/10.sup.6 PBMCs. HIV-1 CRF01_(A)E subtype is neither correlated with HIV-1 DNA reservoir decline nor a prognostic factor for achieving lower HIV-1 DNA levels ([less than or equai to] 2 log.sub.10 copies/10.sup.6 PBMCs) after ART. However, higher HIV-1 DNA level in HIV-1 CRF01_(A)E patients should be aroused much attention and strengthen surveillance during ART.

HIV-1 DNA levels at week 96 were categorized into high, moderate, and low levels, reflecting HIV-1 DNA ≥ 3, 2–3, ≤ 2 log 10 copies/10 6 PBMCs, respectively, and the corresponding proportion of CRF01_AE and non-CRF01_AE subtype were compared. The baseline predictors of low HIV-1 total DNA levels (≤ 2 log 10 copies/10 6 PBMCs) at week 96 were evaluated using a logistic regression model. Results Compared to the non-CRF01_AE subtypes ( n  = 185), patients with CRF01_AE subtype ( n  = 188) harboured a higher level of HIV-1 DNA (median: 3.19 vs. 2.95 log 10 copies/10 6 PBMCs, P  < 0.001) prior to treatment. After 96 weeks of ART, HIV-1 DNA levels remained higher in the CRF01_AE subtype group (median: 2.63 vs. 2.39 log 10 copies/10 6 PBMCs, P  = 0.002). There was no significant difference in the proportion of patients achieving high (22.3% vs. 14.6%, P  = 0.054), moderate (59.6% vs. 60.5%, P  = 0.849) and low levels (18.1% vs 24.9%, P  = 0.111) between CRF01_AE and non-CRF01_AE groups. In the multivariable analysis, baseline HIV-1 DNA level and CD4 + T cell count but not the subtype were independent risk factors for achieving HIV-1 DNA level ≤ 2 log 10 copies/10 6 PBMCs. Conclusion HIV-1 CRF01_AE subtype is neither correlated with HIV-1 DNA reservoir decline nor a prognostic factor for achieving lower HIV-1 DNA levels (≤ 2 log 10 copies/10 6 PBMCs) after ART.
