Background: Mitochondrial DNA (mtDNA) profiles and contributions of mtDNA variants to CD4+T-cell recovery in Euramerican people living with HIV (PLWH) may not be transferred to East-Asian PLWH, highlighting the need to consider more regional studies. We aimed to identify mtDNA characteristics and mutations that explain the variability of short-term CD4+T-cell recovery in East-Asian PLWH. Method: Eight hundred fifty-six newly reported antiretroviral therapy (ART)-naïve Chinese PLWH from the Comparative HIV and Aging Research in Taizhou (CHART) cohort (Zhejiang Province, Eastern China) were enrolled. MtDNA was extracted from peripheral whole blood of those PLWH at HIV diagnosis, amplified, and sequenced using polymerase chain reaction and gene array. Characterization metrics such as mutational diversity and momentum were developed to delineate baseline mtDNA mutational patterns in ART-naïve PLWH. The associations between mtDNA genome-wide single nucleotide variants and CD4+T-cell recovery after short-term (within ~48 weeks) ART in 724 PLWH were examined using bootstrapping median regressions. Results: Of 856 participants, 74.18% and 25.82% were male and female, respectively. The median age was 37 years; 94.51% were of the major Han ethnicity, and 69.04% and 28.62% were of the heterosexual and homosexual transmission, respectively. We identified 2,352 types of mtDNA mutations and mtDNA regions D-loop , ND5 , CYB , or RNR1 with highest mutational diversity or volume. Female PLWH rather than male PLWH at the baseline showed remarkable age-related uptrends of momentum and mutational diversity as well as correlations between CD4+T <200 (cells/μl) and age-related uptrends of mutational diversity in many mtDNA regions. After adjustments of important sociodemographic and clinical variables, m.1005T>C, m.1824T>C, m.3394T>C, m.4491G>A, m.7828A>G, m.9814T>C, m.10586G>A, m.12338T>C, m.13708G>A, and m.14308T>C (at the Bonferroni-corrected significance) were negatively associated with short-term CD4+T-cell recovery whereas m.93A>G, m.15218A>G, and m.16399A>G were positively associated with short-term CD4+T-cell recovery. Conclusion: Our baseline mtDNA characterization stresses the attention to East-Asian female PLWH at risk of CD4+T-cell loss-related aging and noncommunicable chronic diseases. Furthermore, mtDNA variants identified in regression analyses account for heterogeneity in short-term CD4+T-cell recovery of East-Asian PLWH. These results may help individualize the East-Asian immune recovery strategies under complicated HIV management caused by CD4+T-cell loss. [ABSTRACT FROM AUTHOR]

Increasing evidence shows that mitochondrial DNA (mtDNA) variations have an important effect on metabolic disorders, but such studies have not been conducted in HIV-infected patients in Asia. We investigated the distribution of mtDNA haplogroups and their correlation with metabolic disorders in HIV-infected patients. A cross-sectional survey was performed among 296 HIV patients older than the age of 40 years in a rural prefecture, Eastern China. The entire mtDNA sequence was amplified by polymerase chain reaction using four overlapping pairs of primers that have been standardly used. In this sample, mtDNA haplogroups B, D, M7, and F were the most dominant haplogroups. The overall prevalence of metabolic syndrome (MetS) was 36.1%, and was highest (77.8%) among those with haplogroup G and lowest (21.4%) among those with haplogroup M8. In multivariable analysis, haplogroups G and N9 were significantly associated with the presence of MetS [adjusted odds ratio (aOR) = 13.5, 95% confidence interval (CI): 1.9–94.7; aOR = 8.1, 95% CI: 1.8–36.1; respectively]. Moreover, patients with haplogroup G had increased odds of elevated glycated hemoglobin (HbA1c) (aOR = 10.1, 95% CI: 1.4–71.1), patients with haplogroup N9 had increased odds of elevated triglycerides (aOR = 13.5, 95% CI: 2.4–76.8). No significant association between mtDNA haplogroups and other MetS components was observed. Our data demonstrate the association between mtDNA haplogroups and MetS in HIV-infected patients. The Asian-specific mtDNA haplogroups G and N9 may confer higher risk for the development of MetS in HIV-infected patients, which requires further longitudinal investigation. [ABSTRACT FROM AUTHOR]

This retrospective cohort study was conducted from January 2009 to July 2016 to explore the occurrence and risk factors of self-reported fatigue within the first 6 months after receiving antiretroviral treatment (ART) among patients living with HIV in Taizhou City of Zhejiang province, Eastern China. In total, 1163 HIV-infected patients with a median follow-up duration of 27.8 months were included in the analysis. Among them, 261 (22.4%) reported fatigue within the first 6 months after ART. In the multivariable logistic regression analysis, self-reported fatigue within the first 6 months after ART was negatively associated with junior middle-school education or above, baseline CD4 cell count of 200-349 and >350 cells/μL (vs < 200 cells/μL), overweight at baseline (vs normal weight) but positively associated with ≥50 years old at initiation of ART (vs <30 years old), underweight at baseline, use of efavirenz (EFV) in the first-line regimen. Our data suggest that earlier initiation of ART and higher body mass index are preferred to restore the energy of HIV-infected patients with the EFV use in the era of ART in China.

Raw Arecae Semen, the seed of Areca catechu L., as well as Arecae Semen Tostum and Arecae semen carbonisata are traditionally processed by stir-baking for subsequent use in a variety of clinical applications. These three Arecae semen types, important Chinese herbal drugs, have been used in China and other Asian countries for thousands of years. In this study, the sensory technologies of a colorimeter and sensitive validated high-performance liquid chromatography with diode array detection were employed to discriminate raw Arecae semen and its processed drugs. The color parameters of the samples were determined by a colorimeter instrument CR-410. Moreover, the fingerprints of the four alkaloids of arecaidine, guvacine, arecoline and guvacoline were surveyed by high-performance liquid chromatography. Subsequently, Student's t test, the analysis of variance, fingerprint similarity analysis, hierarchical cluster analysis, principal component analysis, factor analysis and Pearson's correlation test were performed for final data analysis. The results obtained demonstrated a significant color change characteristic for components in raw Arecae semen and its processed drugs. Crude and processed Arecae semen could be determined based on colorimetry and high-performance liquid chromatography with a diode array detector coupled with chemometrics methods for a comprehensive quality evaluation.

Objective: Hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection has been proved to be a growing public health concern. The prevalence and genotypic pattern vary with geographic locations. Limited information is available to date with regard to HCV genotype and its clinical implications among those former commercial blood donor communities. The aims of this study were to genetically define the HCV genotype and associated clinical characteristics of HIV/HCV co-infected patients from a region with commercial blood donation history in central China. Methods: A cross sectional study, including 164 HIV infected subjects, was conducted in Shanxi province central China. Serum samples were collected and HCV antibody testing, AST and ALT testing were performed. Seropositive samples were further subjected to RT-PCR followed by direct sequence coupled with phylogenetic analysis of Core-E1 and NS5B regions performed in comparison with known reference genotypes. Findings: A total of 139 subjects were HCV antibody positive. Genotype could be determined for 88 isolates. Phylogenetic analysis revealed that the predominant circulating subtype was HCV 1b (65.9%), followed by HCV 2a (34.1%). The HCV viral load in the subjects infected with HIV1b was significantly higher than those infected with HCV 2a (P = 0.006). No significant difference for HCV RNA level was detected between ART status, CD4+ cell count level and HIV RNA level. Serum AST and ALT level were likely to increase with HCV RNA level, although no significance was observed. Those who had conducted commercial donation later than 1991 (OR 3.43, 95% CI: 1.12–10.48) and had a short duration of donation (OR 0.35, 95% CI: 0.13–0.96) were more likely to be infected with HCV 1b. Conclusion: These results suggest that HCV subtype 1b predominates in this population, and the impact of HIV status and ART on HCV disease progression is not significantly correlated.

Gliosarcoma (GS) represents a rare variant of glioblastoma in the central nervous system, characterized by biphasic histopathological features of gliomatous and sarcomatous components. Here, we present an unusual case of GS, which also demonstrated osteosarcomatous differentiation. A 65-year-old female patient underwent gross total resection (GTR) of the right temporal lobe lesion. Subsequently received 60 Gy external beam radiation therapy and chemotherapy. Postoperative histopathological analysis indicated that the sarcomatous portion of the typical fibrosarcoma pattern mingled with areas of osteoid structure. The molecular pathological analysis demonstrated IDH1/2 wild-type and MGMT promoter island methylated phenotype. Target Enrichment Sequencing (TES) was performed on the gliomatous and sarcomatous components of the tumor tissues. TERT promoter, RB1, NF1, TP53 mutations and copy number variations (CNVs) on chromosome 7, 10q, 11q, 12, 13, 17 and 22 were observed in gliomatous and fibro-sarcomatous mixed tumor tissue; While we found TERT promoter, RB1, TP53 mutations and CNVs on chromosome 2q, 3q, 7, 8, 9, 10, 11, 12, 13, 15, 16, 17, 18, 19 and 22 in osteosarcomatous component. Noteworthy, EGFR amplification was not observed in both gliomatous/fibro-sarcomatous and osteosarcomatous components. Integrated with histopathology, molecular pathology, and genomic alteration analysis, we report a case of GS with an extremely rare histopathologic phenotype of osteosarcomatous differentiation, who also suffered lung multi-metastases. Additionally, synthesizing the literature review, our study of this unusual differentiation of GS into osteosarcoma may provide novel insight into the natural history of GS. [ABSTRACT FROM AUTHOR]

• The first μPADs-based kinetic matching approach for total polyphenol content measurement. • Identical reaction progress achieved on-chip without external facility assistance. • Rapid detection of total polyphenol content of tea within ten minutes. In this work, a facile kinetic matching approach for total polyphenol content (TPC) measurement was developed based on the adoption of microfluidic paper-based analytical devices with symmetric channel distribution. A set of Folin-Ciocalteu reactions performed on the same paper chip were activated all at the same time through synchronized filling of sodium carbonate solution among individual channels. Gallic acid was found valid as a standard compound for kinetic matching measurement of tea samples. TPC of tea infusions was successfully measured within ten minutes without any complexed time control procedure needed. Under the optimized conditions, the new developed method showed good linearity in the TPC range of 10–100 mg/L (r > 0.9955) and the inter-chip precision was 5.6% (n = 11). The results measured with the new developed approach were in good agreement with those with the conventional FC assay. [ABSTRACT FROM AUTHOR]

Objective: Kaposi's sarcoma-associated herpesvirus (KSHV) infection, essential for Kaposi sarcoma development especially in people with HIV (PWH), has been proposed to be transmitted through saliva. The potential role of salivary microbiota played in the infection of KSHV is largely obscure. This study aimed to explore the association between salivary microbiota and KSHV infection among PWH., Design: Cross-Sectional Study., Methods: During May to Dec 2022, we conducted a cross-sectional study among PWH in Ili prefecture Xinjiang, China. Participants completed face-to-face questionnaires, plasma and saliva samples were collected to assay KSHV infection status and 16S rRNA sequencing. We distinguished demographic characteristics between groups with/without KSHV, and compared the α and β diversity of the salivary microbiota. LEfSe identified key bacterial genera for Random Forest and XGBoost models to recognize the important discriminatory features., Results: Among 876 PWH in Xinjiang, 38.7% were KSHV seropositive. Regression models indicated that moderate drinking, absence of dental treatment history, higher CD4 counts, and higher CD4/CD8 ratios were negatively associated with KSHV seropositivity. LEfSe analysis demonstrated that 14 bacterial genera were significantly enriched at the genus level in the group with/without KSHV. Machine learning analyses gave an AUC of 0.66 for Random Forest and 0.85 for XGBoost in predicting KSHV infection status. The bacterial genera, including Alloprevotella, Fusobacterium, Prevotella&#95;7, Porphyromonas, Rothia, and Leptotrichia, were identified as important discriminatory features., Conclusions: This study suggests the potential role of salivary microbiota in KSHV transmission among PWH. Identified microbial genera offer promising biomarkers for monitoring and managing KSHV in PWH., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Background: Genome instability plays a crucial role in promoting tumor development. Germline mutations in genes responsible for DNA repair are often associated with familial cancer syndromes. A noticeable exception is the CHEK1 gene. Despite its well-established role in homologous recombination, germline mutations in CHEK1 are rarely reported., Case Presentation: In this report, we present a patient diagnosed with ovarian clear cell carcinoma who has a family history of cancer. Her relatives include a grandfather with esophageal cancer, a father with gastric cancer, and an uncle with a brain tumor. The patient carried a typical genomic profile of clear cell carcinoma including mutations in KRAS , PPP2R1A , and PIK3R1 . Importantly, her paired peripheral blood cells harbored a germline CHEK1 mutation, CHEK1 exon 6 c.613 + 2T>C , which was also found in her father. Unfortunately, the CHEK1 status of her grandfather and uncle remains unknown due to the unavailability of their specimens. Further evaluation via RT-PCR confirmed a splicing error in the CHEK1 gene, resulting in truncation at the kinase domain region, indicative of a loss-of-function mutation., Conclusion: This case highlights a rare germline CHEK1 mutation within a family with a history of cancer. The confirmed splicing error at the mRNA level underscores the functional consequences of this mutation. Documenting such cases is vital for future evaluation of inheritance patterns, clinical penetrance of the mutation, and its association with specific cancer types., Competing Interests: Authors YL, HC, and SZ were employed by the company Suzhou Sano Precision Medicine Ltd.

This study aimed to study the relationship between the expression levels of inflammatory mediators IL-36β and IL-36R and disease symptoms, laboratory indices and somatic immune function in Systemic Lupus Erythematosus (SLE) of different stages. In this research 70 patients with SLE who were treated in public hospitals from February 2020 to December 2021 were randomly divided into the stable group (n=35) and active group (n=35), and serum IL-36 was measured in the two groups β and IL-36R concentration with the standard curve of Enzyme-Linked Immunosorbent Assay (ELISA) to analyze IL-36β and IL-36R concentrations. 36β and IL-36R concentrations were analyzed in relation to the Disease activity score of systemic lupus erythematosus (SLEDAI), disease duration, typical symptoms of SLE and experimental characteristics. Results showed that the differences in IL-36β and IL-36R concentrations between the stable and active groups overall and for each disease duration group were tiny. There was no significant correlation between serum IL-36β and IL-36R concentrations and SLEDAI scores in stable and active patients, and a negative correlation between them and disease duration. Serum inflammatory mediator IL-36R concentrations were significantly higher in patients with mucosal ulcers and the difference was statistically significant. differences in IL-36β concentrations were statistically significant only for indicators of decreased erythrocyte count and IL-36R concentrations were statistically significant for indicators of decreased erythrocyte count, decreased haemoglobin and decreased lymphocytes The differences were huge and tiny in C4 decline, anti-dsDNA, and urinary routine protein. There was a significant positive correlation between IL-36β and IL-36R concentrations in patients with stable and active SLE, with correlation coefficients of 0.448 and 0.452 respectively. The differences in IL-36β and IL-36R concentrations between the stable and active groups were tiny for patients in the stable and active groups as a whole and for all disease groups. The differences in the number of each inflammatory mediator positive cells in the epidermal stratum corneum and superficial dermis between patients in the stable and active groups were tiny. In conclusion, IL-36β and IL-36R proteins in SLE patients are expressed in immune cells as well as epithelial cells of patients, indicating that these two inflammatory mediators may be one of the early signals that activate the immune system of SLE patients and trigger the immune response of patients; the onset of SLE may be associated with the inflammatory response induced by IL-36β and IL-36R.

Neurotrophic tyrosine receptor kinase ( NTRK ) rearrangements are oncogenic drivers of various types of adult and pediatric tumors, including gliomas. However, NTRK rearrangements are extremely rare in glioneuronal tumors. Here, we report a novel NTRK2 rearrangement in a 24-year-old female with dysembryoplastic neuroepithelial tumor (DNT), a circumscribed WHO grade I benign tumor associated with epilepsy. By utilizing targeted RNA next-generation sequencing (NGS), fluorescence in situ hybridization (FISH), reverse transcriptase PCR (RT-PCR), and Sanger sequencing, we verified an in-frame fusion between NTRK2 and the lipoma HMGIC fusion partner-like 3 ( LHFPL3 ). This oncogenic gene rearrangement involves 5' LHFPL3 and 3' NTRK2 , retaining the entire tyrosine kinase domain of NTRK2 genes. Moreover, the targeted DNA NGS analysis revealed an IDH1 (p.R132H) mutation, a surprising finding in this type of tumor. The pathogenic mechanism of the LHFPL3::NTRK2 in this case likely involves aberrant dimerization and constitutive activation of RTK signaling pathways., Competing Interests: Authors PC, SuZ, and ShZ were employed by Suzhou Sano Precision Medicine Ltd.

Raw Moutan Cortex (RMC) is a traditional medicinal material commonly used in China. Moutan Cortex Carbon (MCC) is a processed product of RMC by stir-frying. As raw and processed products of the same Chinese herb pieces, they have different effects. RMC has the effects of clearing heat and cooling blood, promoting blood circulation and removing blood stasis, but MCC has the contrary effect of cooling blood and hemostasis. Therefore, it is necessary to distinguish them effectively. The traditional quality evaluation method of RMC and MCC still adopts character identification, and mainly relies on the working experience and sensory judgment of employees with experience. This will lead to strong subjectivity and poor repeatability. And the final evaluation result may cause inevitable errors and the processed products with different processing degrees in actual production, which affects the clinical efficacy. In this study, the electronic nose technology was introduced to objectively digitize the odor of RMC and MCC. And the discrimination model of RMC and MCC was constructed in order to establish a rapid, objective and stable quality evaluation method of RMC and MCC. According to the correlation analysis, the experiment found the content of gallic acid, 5-hydroxymethylfurfural (5-HMF), paeoniflorin and paeonol determined by high performance liquid chromatography (HPLC) had a certain correlation with their odor characteristics. Thus, partial least squares regression (PLSR) and support vector machine regression (SVR) were compared and established the chemical composition quantitative model. Results showed that the quantitative data of RMC and MCC odor could be used to predict the contents of the chemical components. It can be used for quality control of RCM and MCC.

Background: Emerging evidence shows that long non-coding RNAs (lncRNAs) play a crucial role in tumor development by regulating biological behavior in various cancer cells. Several lncRNAs act as miRNA sponges by binding miRNA sequences and thus regulating mRNA expression. The lncRNA maternally expressed gene 3 (MEG3) has decreased expression levels in many cancer cells and acts as a tumor suppressor in different cancers. MEG3 also showed decreased expression in nasopharyngeal carcinoma (NPC) and plays a role in tumor suppression; however, the detailed mechanism of tumor suppression in NPC cells has not been reported. This paper aimed to explore the function and molecular mechanisms of MEG3 in the development of NPC., Methods: MEG3 and miR-543 levels in NPC cells were detected by quantitative real-time PCR (qRT-PCR). The regulatory role of MEG3 in NPC cells was examined using knockdown and overexpression of MEG3 in C666-1 cells. Cell proliferation was analyzed by the cell counting kit-8 (CCK-8) assay, cell migration and invasion capacities were evaluated using Transwell assay, and cell apoptosis was assessed using flow cytometry. The relationship between MEG3 and miR-543 was investigated by luciferase reporter assay. MEG3- and Krüppel like factor 4 (KLF4)-mediated changes in NPC cell proliferation and apoptosis were analyzed, and KLF4, Bcl-2 and Bax protein expression levels were measured by western blotting., Results: The results showed that MEG3 was decreased and miR-543 was increased in NPC cell lines, and upregulated MEG3 inhibited cell proliferation, migration, and invasion and promoted apoptosis, suggesting that MEG3 acts as a tumor suppressor in NPC cells. Furthermore, a luciferase reporter assay and western blotting indicated that MEG3 regulated KLF4 expression by sponging miR-543. Functionally, overexpression of MEG3 suppressed cell proliferation, promoted cell apoptosis and affected Bcl-2 and Bax protein levels via regulation of KLF4 expression mediated by sponging miR-543., Conclusions: These findings show that lncRNA MEG3 inhibits the development of NPC by sponging miR-543 targeting KLF4 and that MEG3 can serve as a new novel target for NPC therapeutics., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tcr.2019.12.41).

Moutan Cortex charcoal has been used to ameliorate blood heat symptoms and treat pathologic hemorrhage down the ages. Although well known as an agent with the effect of astringency and hemostasis, its active ingredients and action mechanism remain unclear. In the present study, molecular docking technology was employed to screen the potential hemostatic compounds in Moutan Cortex charcoal and their target proteins. Protein-protein-interaction (PPI) analysis was performed to explain the functions and enrichment pathways of the target proteins. The results showed that a total of 25 compounds were estimated as active constituents targeting multiple proteins related to hemostatic diseases, including 5 proteins (SERPINC1, FVIII, FX, FII and FXII) that were considered as the key targets. Then the drug-target (D-T) network was constructed to analyze the underlying hemostatic mechanism of Moutan Cortex charcoal, followed by a hierarchical cluster analysis (HCA) for compounds clustering, and a coagulation screening test for compound verification on their coagulation activities, with the results indicating that M15 (5-Tetradecenoic acid) and M31 (1-Monolinolein) might be the key compounds contributing to the hemostasis effect of Moutan Cortex charcoal by involving in the pathways related to complement, coagulation cascades and the platelet activation, particularly by activating FVIII, FX, FII and FXII and inhibiting SERPINC1. This study has demonstrated that Moutan Cortex charcoal may work as a hemostatic through the interaction between multiple-compounds and multiple-proteins, which provides the basis for further researches on the hemostasis mechanism of Moutan Cortex charcoal.

Growing evidence suggests that HIV infection may accelerate biological aging. Insomnia symptoms, particularly in later life, exacerbate cellular aging. We examined the association between insomnia symptoms and leukocyte telomere length (LTL), and further explored how this association was affected by HIV serostatus and age. Data were assessed from 244 HIV-infected individuals ≥40 years and 244 HIV-uninfected individuals who were frequency-matched by age, gender and education level. Insomnia symptoms were assessed by responses to four sleep-related questions covering the past month. We performed multivariable linear regression with logarithmically transformed LTL and reported exponentiated coefficients. HIV-infected individuals had shorter LTL compared to uninfected individuals (geometric mean 0.82 vs 0.89, P= 0.052), and this association remained after adjustment for gender, education level, and smoking history (-7.4%, P= 0.051) but markedly attenuated after additional adjustment for insomnia and depressive symptoms (-3.7%, P= 0.367). Significant interactions between age group (55-82 vs 40-54 years) and insomnia symptoms on LTL were observed in the HIV-infected individuals (-28.4%, P =0.033) but not the uninfected (-17.9%, P= 0.250) . After stratifying by age group, LTL was independently associated with insomnia symptoms in those 55 years and older among the HIV-infected individuals (-24.5%, P= 0.026) but not those 40-54 years old (-9.8%, P= 0.428). Our findings suggest that elevated insomnia and depressive symptoms may partly explain the correlation between HIV serostatus and shorter LTL. Significant association between insomnia and shorter LTL observed in elderly HIV-infected but not in uninfected individuals suggest that such adverse effect may begin at an earlier age or is more pronounced in HIV-infected individuals but requires further investigation., Competing Interests: Conflicts of interest The authors declare no conflict of interests.
