Prevalence and risk factors of tuberculosis among people living with HIV/AIDS in China: a systematic review and meta-analysis.

OBJECTIVE: To estimate the prevalence and risk factors associated with tuberculosis (TB) among people living with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) in China. METHODS: A systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. After the literature was screened based on the inclusion and exclusion criteria, STATA® version 17.0 software was used for the meta-analysis. The heterogeneity among study data was assessed using I2 statistics. Subgroup analysis and meta-regressions were performed to further explore the source of heterogeneity. RESULTS: A total of 5241 studies were retrieved. Of these, 44 studies were found to be eligible. The pooled prevalence of HIV/TB co-infection was 6.0%. The risk factors for HIV/TB co-infection included a low CD4+ T cell count, smoking, intravenous drug use and several other sociodemographic and clinical factors. Bacillus Calmette-Guérin (BCG) vaccination history was a protective factor. CONCLUSION: A high prevalence of TB was observed among people living with HIV/AIDS in China. Low CD4+ T cell count, smoking, and intravenous drug use were the primary risk factors for HIV/TB co-infection, whereas BCG vaccination history was a protective factor. Checking for TB should be prioritized in HIV screening and healthcare access. SYSTEMATIC REVIEW REGISTRATION: Registered on PROSPERO, Identifier: CRD42022297754.

Curcuma Longa Induces the Transcription Factor FOXP3 to Downregulate Human Chemokine CCR5 Expression and Inhibit HIV-1 Infection.

HIV mutations occur frequently despite the substantial success of combination antiretroviral therapy, which significantly impairs HIV progression. Failure to develop specific vaccines, the occurrence of drug-resistant strains, and the high incidence of adverse effects due to combination antiviral therapy regimens call for novel and safer antivirals. Natural products are an important source of new anti-infective agents. For instance, curcumin inhibits HIV and inflammation in cell culture assays. Curcumin, the principal constituent of the dried rhizomes of Curcuma longa L. (turmeric), is known as a strong anti-oxidant and anti-inflammatory agent with different pharmacological effects. This work aims to assess curcumin's inhibitory effects on HIV in vitro and to explore the underpinning mechanism, focusing on CCR5 and the transcription factor forkhead box protein P3 (FOXP3). First, curcumin and the RT inhibitor zidovudine (AZT) were evaluated for their inhibitory properties. HIV-1 pseudovirus infectivity was determined by green fluorescence and luciferase activity measurements in HEK293T cells. AZT was used as a positive control that inhibited HIV-1 pseudoviruses dose-dependently, with IC50 values in the nanomolar range. Then, a molecular docking analysis was carried out to assess the binding affinities of curcumin for CCR5 and HIV-1 RNase H/RT. The anti-HIV activity assay showed that curcumin inhibited HIV-1 infection, and the molecular docking analysis revealed equilibrium dissociation constants of [Formula: see text]9.8[Formula: see text]kcal/mol and [Formula: see text]9.3[Formula: see text]kcal/mol between curcumin and CCR5 and HIV-1 RNase H/RT, respectively. To examine curcumin's anti-HIV effect and its mechanism in vitro, cell cytotoxicity, transcriptome sequencing, and CCR5 and FOXP3 amounts were assessed at different concentrations of curcumin. In addition, human CCR5 promoter deletion constructs and the FOXP3 expression plasmid pRP-FOXP3 (with an EGFP tag) were generated. Whether FOXP3 DNA binding to the CCR5 promoter was blunted by curcumin was examined using transfection assays employing truncated CCR5 gene promoter constructs, a luciferase reporter assay, and a chromatin immunoprecipitation (ChIP) assay. Furthermore, micromolar concentrations of curcumin inactivated the nuclear transcription factor FOXP3, which resulted in decreased expression of CCR5 in Jurkat cells. Moreover, curcumin inhibited PI3K-AKT activation and its downstream target FOXP3. These findings provide mechanistic evidence encouraging further assessment of curcumin as a dietary agent used to reduce the virulence of CCR5-tropic HIV-1. Curcumin-mediated FOXP3 degradation was also reflected in its functions, namely, CCR5 promoter transactivation and HIV-1 virion production. Furthermore, curcumin inhibition of CCR5 and HIV-1 might constitute a potential therapeutic strategy for reducing HIV progression.

Traditional Chinese Medicine in Treatment of COVID-19 and Viral Disease: Efficacies and Clinical Evidence.

Coronavirus disease 2019 (COVID-19) remains an uncontained, worldwide pandemic. While battling the disease in China, the Chinese government has actively promoted the use of traditional Chinese medicine, and many studies have been conducted to determine the efficacy of traditional Chinese medicine for treating COVID-19. The present review discusses the effectiveness and safety of traditional Chinese medicine in curing COVID-19 and provides clinical evidence from all confirmed cases in China. Applications of traditional Chinese medicine and specific recipes for treating other viral infections, such as those caused by severe acute respiratory syndrome coronavirus and influenza A viruses (including H1N1), are also discussed. Studies have reported that traditional Chinese medicine treatment plays a significant role in improving clinical symptoms. Therefore, further investigation may be of high translational value in revealing novel targeted therapies for COVID-19.

Effects of the carbon/nitrogen (C/N) ratio on a system coupling simultaneous nitrification and denitrification (SND) and denitrifying phosphorus removal (DPR).

Simultaneous nitrification and denitrification (SND) were coupled with a denitrifying phosphorus removal (DPR) to achieve simultaneous nutrient and carbon removal. With influent chemical oxygen demand (COD), ammonia-N (NH4+-N), and total phosphorus (TP) concentrations of 250, 50, and 8 mg/L, the SND-DPR coupled system achieved stable nutrient removal efficiency of COD, NH4+-N, TN and TP were 91.8 ± 1.7%, 88.4 ± 1.8%, 64 ± 3.3% and 99.2 ± 0.6%, respectively. Enhancing the C/N ratio strengthened the storage of intracellular polymers and provided sufficient intracellular carbon sources for phosphorus uptake. The nutrient removal efficiency reached the highest level at a C/N ratio of 5, and no advantage was observed after increasing the C/N ratio to 7. Nutrients were mainly removed during the aerobic stage at a low DO concentration as well during the anoxic stage, which helped achieve concurrent nitrification and denitrification by ordinary heterotrophic organisms (OHOs), promote denitrifying and aerobic phosphorus removal, and conserve organic carbon demand and energy consumption for aeration. The system was limited for DO in the aerobic stage at a low DO concentration, resulting in a deficiency in electron acceptors (O2 and NO3-N) and limiting the subsequent promotion of phosphorus uptake and TN removal. The limited DO content in the low DO stage was the key factor involved in enhancing the nutrient removal efficiency along with the increasing influent C/N ratio.

Urotensin II and urantide exert opposite effects on the cellular components of atherosclerotic plaque in hypercholesterolemic rabbits.

Increasing levels of plasma urotensin II (UII) are positively associated with atherosclerosis. In this study we investigated the role of macrophage-secreted UII in atherosclerosis progression, and evaluated the therapeutic value of urantide, a potent competitive UII receptor antagonist, in atherosclerosis treatment. Macrophage-specific human UII-transgenic rabbits and their nontransgenic littermates were fed a high cholesterol diet for 16 weeks to induce atherosclerosis. Immunohistochemical staining of the cellular components (macrophages and smooth muscle cells) of aortic atherosclerotic lesions revealed a significant increase (52%) in the macrophage-positive area in only male transgenic rabbits compared with that in the nontransgenic littermates. However, both male and female transgenic rabbits showed a significant decrease (45% in males and 31% in females) in the smooth muscle cell-positive area compared with that of their control littermates. The effects of macrophage-secreted UII on the plaque cellular components were independent of plasma lipid level. Meanwhile the wild-type rabbits were continuously subcutaneously infused with urantide (5.4 µg· kg-1· h-1) using osmotic mini-pumps. Infusion of urantide exerted effects opposite to those caused by UII, as it significantly decreased the macrophage-positive area in male wild-type rabbits compared with that of control rabbits. In cultured human umbilical vein endothelial cells, treatment with UII dose-dependently increased the expression of the adhesion molecules VCAM-1 and ICAM-1, and this effect was partially reversed by urantide. The current study provides direct evidence that macrophage-secreted UII plays a key role in atherogenesis. Targeting UII with urantide may promote plaque stability by decreasing macrophage-derived foam cell formation, which is an indicator of unstable plaque.

Advantages of Chinese Medicine for Patients with Acquired Immunodeficiency Syndrome in Rural Central China.

OBJECTIVE: To analyze the effect of Chinese medicine (CM) on mortality and quality of life (QOL) of acquired immunodefificiency syndrome (AIDS) patients treated with combined antiretroviral therapy (cART). METHODS: A random sample of AIDS patients enrolled in the National Chinese Medicine Treatment Trial Program (NCMTP) that met the inclusion criteria was included in this study. NCMTP patients were included as the CM+cART group, and those not in the NCMTP were included as the cART group. Survival from September 2004 to September 2012 was analyzed by retrospective cohort study. QOL was analyzed by cross-sectional study. RESULTS: The retrospective cohort study included 528 AIDS patients, 322 in the CM+cART group and 206 in the cART group. After 8 years, the mortality in the CM+cART group was 3.3/100 person-years, which was lower than the cART group of 5.3/100 person-years (P<0.05). The hazard ratio (HR) for mortality in the cART group was 1.6 times that of the CM+cART group by Cox proportional hazard model analysis. After controlling for gender, age, marital status, education, and CD4+ T-cell count, the HR was 1.9 times higher in the cART group compared with the CM+cART group (P<0.05). The cross-sectional study investigated 275 AIDS patients. The mean scores of all QOL domains except spirituality/personal beliefs were higher in the CM+cART group than in the cART group (P<0.05). CONCLUSIONS: For AIDS patients, CM could help to prolong life, decrease mortality, and improve QOL. However, there were limitations in the study, so prospective studies should be carried out to confifirm our primary results.

Governor vessel moxibustion: Ancient Chinese medical technology with new vitality.

Moxibustion is an ancient therapeutic technique used in Chinese medicine. Governor Vessel moxibustion (GVM) was developed from long snake moxibustion, a popular technique used in China's Jiangsu and Zhejiang Provinces, and is significantly more effective than general moxibustion. We aimed to review GVM, including its theoretical basis, choices of moxibustion points and materials, operation procedures, clinical applications, and contraindications. This information could increase the appropriate use of GVM and support further in-depth research.

Naf1 Regulates HIV-1 Latency by Suppressing Viral Promoter-Driven Gene Expression in Primary CD4+ T Cells.

HIV-1 latency is characterized by reversible silencing of viral transcription driven by the long terminal repeat (LTR) promoter of HIV-1. Cellular and viral factors regulating LTR activity contribute to HIV-1 latency, and certain repressive cellular factors modulate viral transcription silencing. Nef-associated factor 1 (Naf1) is a host nucleocytoplasmic shuttling protein that regulates multiple cellular signaling pathways and HIV-1 production. We recently reported that nuclear Naf1 promoted nuclear export of unspliced HIV-1 gag mRNA, leading to increased Gag production. Here we demonstrate new functions of Naf1 in regulating HIV-1 persistence. We found that Naf1 contributes to the maintenance of HIV-1 latency by inhibiting LTR-driven HIV-1 gene transcription in a nuclear factor kappa B-dependent manner. Interestingly, Naf1 knockdown significantly enhanced viral reactivation in both latently HIV-1-infected Jurkat T cells and primary central memory CD4+ T cells. Furthermore, Naf1 knockdown in resting CD4+ T cells from HIV-1-infected individuals treated with antiretroviral therapy significantly increased viral reactivation upon T-cell activation, suggesting an important role of Naf1 in modulating HIV-1 latency in vivo Our findings provide new insights for a better understanding of HIV-1 latency and suggest that inhibition of Naf1 activity to activate latently HIV-1-infected cells may be a potential therapeutic strategy. IMPORTANCE: HIV-1 latency is characterized mainly by a reversible silencing of LTR promoter-driven transcription of an integrated provirus. Cellular and viral proteins regulating LTR activity contribute to the modulation of HIV-1 latency. In this study, we found that the host protein Naf1 inhibited HIV-1 LTR-driven transcription of HIV genes and contributed to the maintenance of HIV-1 latency. Our findings provide new insights into the effects of host modulation on HIV-1 latency, which may lead to a potential therapeutic strategy for HIV persistence by targeting the Naf1 protein.

The variances of Sp1 and NF-κB elements correlate with the greater capacity of Chinese HIV-1 B'-LTR for driving gene expression.

The 5' end of HIV-1 long terminal repeat (LTR) serves as a promoter that plays an essential role in driving viral gene transcription. Manipulation of HIV-1 LTR provides a potential therapeutic strategy for suppressing viral gene expression or excising integrated provirus. Subtype-specific genetic diversity in the LTR region has been observed. The minor variance of LTR, particularly in the transcription factor binding sites, can have a profound impact on its activity. However, the LTR profiles from major endemic Chinese subtypes are not well characterized. Here, by characterizing the sequences and functions of LTRs from endemic Chinese HIV-1 subtypes, we showed that nucleotide variances of Sp1 core promoter and NF-κB element are associated with varied LTR capacity for driving viral gene transcription. The greater responsiveness of Chinese HIV-1 B'-LTR for driving viral gene transcription upon stimulation is associated with an increased level of viral reactivation. Moreover, we demonstrated that the introduction of CRISPR/dead Cas9 targeting Sp1 or NF-κB element suppressed viral gene expression. Taken together, our study characterized LTRs from endemic HIV-1 subtypes in China and suggests a potential target for the suppression of viral gene expression and a novel strategy that facilitates the accomplishment of a functional cure.

[Breakthrough Point of Chinese Medicine and Pharmacy for HIV/AIDS Prevention and Treatment in the Post-HAART Period].

HIV/AIDS is a severe infectious disease with ineffective drug or method found till now. Highly active antiretroviral therapy (HAART) is a treatment method widely internationalized. Its coverage populations are continually expanding due to its definite clinical effect. AIDS prevented and treated by Chinese medicine and pharmacy has ever been reported. Especially early intervention of Chinese medicine syndrome differentiation based treatment can delay the process of HIV-infected subjects' entry into AIDS in AIDS asymptomatic phase. However, it has great significance of clinical and basic researches in the following 4 aspects: (1) attenuating toxic/adverse reactions of HAART; (2) improving clinical effects of HAART; (3) lowering resistance rate of HAART; and (4) treating common opportunistic infections of AIDS in the post-HAART period.

Effectiveness and safety of traditional Chinese medicine in treating acquired immune deficiency syndrome: 2004-2014.

Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

Unified-planning, graded-administration, and centralized-controlling: a management modality for treating acquired immune deficiency syndrome with Chinese medicine in Henan Province of China.

Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

[Research on Chinese medicine syndrome distribution of asymptomatic HIV infection patients].

OBJECTIVE: To explore Chinese medicine syndrome distribution laws of asymptomatic HIV infection patients. METHODS: Using Chi-square test, Chinese medicine syndrome distribution laws were compared and analyzed in 1 156 asymptomatic HIV infection patients from March 2009 to October 2011 from four aspects, i.e., age, possible infection time, disease duration, and different routes of infection. RESULTS: Qi deficiency syndrome (QDS) and internal dampness-heat accumulation syndrome (IDHAS) were dominant in all syndrome types. Along with aging, QDS showed a growing tendency, while IDHAS showed obvious declining tendency. There was no obvious change in other syndrome types. There was statistical difference in the distribution of each syndrome type among each age period (P < 0.01). Within 15 years, along with the increase of infection time, QDS showed a growing tendency, while IDHAS ratio showed an obvious declining tendency. No obvious laws were found in other syndrome types. There was statistical difference in the distribution of each syndrome type (P < 0.01). Along with the prolongation of disease duration, the case number of each syndrome showed a decreasing trend, but QDS and IDHAS still accounted for higher ratios in each stage. There was statistical difference in the distribution of each syndrome type (P < 0.01). As for infection routes, QDS was predominant in paid blood donation, blood transfusion infection, intravenous drugs. IDHAS was predominant in sexual transmit. No obvious laws were found in other syndrome types. There was statistical difference in the distribution of each syndrome type (P < 0.01). CONCLUSIONS: DIS, IDHAS, and no confirmable syndrome typing were dominant in asymptomatic HIV infection patients. Deficiency and dampness were important pathological factors for them.

Treatment of acquired immunodeficiency syndrome with Chinese medicine in China: opportunity, advancement and challenges.

Chinese medicine (CM) has been used in the treatment of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) for 30 years and the demonstrated therapeutic effects of CM, such as reducing plasma HIV viral load, increasing CD4(+)T cell counts, promoting immunity reconstitution, ameliorating symptoms and signs, improving the health related quality of life (HRQOL) and counteracting against the effects of anti-retroviral drugs, were summarized and reviewed in this article. The authors point out that it had been a good opportunity to use CM for the treatment of HIV infection and AIDS in the past and also there are huge challenges ahead for CM research and clinicians to discover more effective CM and its underlying mechanisms for treatment of AIDS.

[Preliminary study on features of syndrome distribution and cluster analysis for AIDS patients with pulmonary infection].

OBJECTIVE: To investigate Chinese medical features of acquired immunodeficiency syndrome (AIDS) patients with pulmonary infection. METHODS: Using cluster analysis method, Chinese medical syndromes of 196 AIDS patients with pulmonary infection were analyzed. The distribution features of each syndrome type were analyzed according to the severity and CD4+ numerical analysis. RESULTS: Basic Chinese medical syndrome types could be summed up as three kinds: exterior invasion of wind heat and phlegm heat obstructing Fei syndrome (61 cases, 31.1%), Fei-Pi deficiency and Fei stagnation of phlegm syndrome (64 cases, 32.7%), Fei-Shen deficiency and yin deficiency induced inner heat syndrome (71 cases, 36.2%). There was statistical difference in the severity degree and the distribution of CD4 among the three syndrome types (P < 0.05). CONCLUSIONS: AIDS patients with pulmonary infection involve Fei, Shen, and Pi. The pathogenic factors were related to "wind", "heat", "phlegm", and "xu". The Chinese medical syndrome distribution was closely correlated with patients' immunity.
