Abstract
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.

Abstract
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.

Abstract
Chylous pneumonia is a rare respiratory disease. The main clinical manifestation is coughing up chylous sputum with a variety of causes which can be clarified by lymphangiography. The lack of understanding of the disease, and infrequent lymphangiography have led to a high rate of misdiagnosis and missed diagnosis. Here, we reported a case of bronchial lymphatic fistula caused by lymphatic abnormality that led to the diagnosis and treatment of chylous pneumonia, with the aim of improving clinicians' understanding of this disease.

Abstract
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.

Abstract
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.

Abstract
Coronatine (COR) is a non-host specific phytotoxin secreted by Pseudomonas syringae pv. tomato that can induce leaf chlorosis and increase the virulence of pathogens during plant-pathogen interactions. Studies have shown that COR can regulate multiple physiological processes in plants, but its involvement in bacterial pathogenesis and plant growth regulation is not well understood. In this study, transcriptome sequencing was carried out on 4-week-old tomato leaves that were either mock-treated or treated with COR. Transcriptome sequencing led to the identification of 6144 differentially expressed genes (DEGs), of which 4361 genes were downregulated and 1783 genes were upregulated upon COR treatment. To obtain functional information on the DEGs, we annotated these genes using GO and KEGG databases. Functional classification analysis showed that the DEGs were primarily involved in photosynthesis, chlorophyll and carotenoid biosynthesis, jasmonic acid (JA) synthesis and phenylpropane metabolism. A total of 23 genes related to chlorophyll biosynthesis had significant changes, of which 22 genes were downregulated and one gene was upregulated, indicating that chlorophyll biosynthesis was inhibited upon COR treatment. A total of 17 photosystem I related genes and 22 photosystem II related genes involving 20 protein subunits were also downregulated. In the JA synthesis pathway, 25 genes were up regulated, and six genes were downregulated in COR treated samples. COR was also involved in the regulation of multiple secondary metabolites. The identified DEGs will help us better understand the virulence effects and physiological functions of COR and provide a theoretical basis for breeding resistance into economically important crops.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE To observe the effect of Qingfei Peiyuan Micro-pill (QPM) on HIV/AIDS patients with pulmonary infection of phlegm heat obstructing lung syndrome (PHOLS). METHODS Totally 141 HIV/AIDS patients with pulmonary infection of PHOLS were randomly assigned to the treatment group (94 cases) and the control group (47cases). On the basis of Western medicine, patients in the treatment group took QPM. The therapeutic course for all was 28 days. The improvement of symptoms and signs was observed. The body temperature (BT), chest X ray, and white blood cells (WBCs) were detected. RESULTS The Chinese medical syndrome score was lower in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The efficacy was better in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The BT was lower in the treatment group than in the control group on the 7th day. There was no statistical difference in the patient number with normal WBCs on the 7th day (P > 0.05). But there was statistical difference in the patient number with normal WBCs on the 14th, 21st, and 28th day of treatment (P < 0.05). There was no statistical difference in the patient number with normal chest X ray on the 7th and 28th day of treatment (P > 0.05). But there was statistical difference in the patient number with normal chest X ray on the 14th and 21 st day of treatment (P < 0.05). CONCLUSION QPM had certain complementary effect on HIV/AIDS patients with pulmonary infection of PHOLS.

Abstract
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.

Abstract
OBJECTIVE To investigate the distributive path and proliferative rule of marrow mesenchymal stem cells (MSCs) in the rat transplanted via caudal vein from male rat to female rats model of chronic aristolochic acid nephropathy (CAAN). METHODS Cells taken from femoral bone marrow of male Wistar rats were made into single cell suspension, cultured, purified and identified as MSCs. MSCs were transplanted via caudal vein into 50 female Wistar CAAN model rats allocated in the test group, they were killed, 10 rats in a batch, at various time points (6 h, 48 h, 10 d, 30 d and 60 d after transplantation). Besides, 10 rats allocated in the control group were killed on the 30th day after received sham-transplantation. Kidney tissue of all rats was taken for detecting cells originated from the donors by fluorescence in situ hybridization test with FAM-labeled sex determining region of Y chromosome (SRY FISH) probe, and their number in SRY was counted using SRY PCR. RESULTS MSCs were mainly distributed in the glomerular capillaries at the time points of 6 h and 48 h, but the number of MSCs in glomerular capillaries decreased and those in renal mesenchyma increased at the time points from 10 d to 60 d gradually, then tended to a steady state, meanwhile it showed a stable increasing trend in renal tubule. Cell colony of MSCs could be found in mesenchyma with a slowed down increasing between 30 d to 60 d, but the increasing in tubule was still steady. CONCLUSION MSCs originated from the donor can enter the kidney of acceptor and distribute from blood capillary to renal mesenchyma and tubule, and they can long time inhabit there and make propagation.

Abstract
Hearing impairment is the most common disorder of sensorineural function and is an economically and socially important cause of human morbidity. A large-scale epidemiological survey of hearing loss was conducted with 126,876 unselected subjects (63,741 male and 63,135 female) from Sichuan, China. The overall prevalence of hearing loss was 3.28% (4,164 of 126,876), and the prevalence increased with age, reaching 12.8% (1,465 of 11,421) at 60 years of age. In 73.03% of all cases (3,041 of 4,164), the hearing loss was sensorineural, and in 20.39% (849 of 4,164), it was conductive; the remaining cases (6%) were mixed hearing loss. Bilateral loss was found in 74.5% of cases (3,103 of 4,164). In 63.79% of cases (2,656 of 4,164), the degree of hearing loss was less than 55 dB hearing level (HL), and in 5.67% of cases (236 of 4,164), it was greater than 90 dB HL. The prevalence of hearing loss in childhood (<15 years of age) was 0.67% (227 of 34,157), of which 57.7% of cases were conductive and 38.8% were sensorineural. The prevalence of genetic hearing loss was 0.28% (349 of 126,876). Persons who lived in the flatlands appeared to have a higher prevalence than those who lived in the hills. Several ethnic groups, including Tibetans, the Yi, and the Lisu, had a higher prevalence of hearing loss. Presbycusis, otitis media, and genetic factors were the most commonly recognized causes of hearing impairment overall, but otitis media and genetic factors were the main causes of hearing loss in children. Causes for the observed differences in prevalence and etiologic factors between China and industrialized countries will be discussed. In China, infections and genetic factors appear to be of major importance as causes of hearing loss.

Abstract
Mutations in the GJB3 gene encoding connexin31 (Cx31) can cause a dominant non-syndromic form of hearing loss (DFNA2). To determine whether mutations at this locus can also cause recessive non-syndromic deafness, we screened 25 Chinese families with recessive deafness and identified in two families affected individuals who were compound heterozygotes for Cx31 mutations. The three affected individuals in the two families were born to non-consanguineous parents and had an early onset bilateral sensorineural hearing loss. In both families, differing SSCP patterns were observed in affected and unaffected individuals. Sequence analysis in both families demonstrated an in-frame 3 bp deletion (423-425delATT) in one allele, which leads to the loss of an isoleucine residue at codon 141, and a 423A-->G transversion in the other allele, which creates an Ile-->Val substitution at codon 141 (I141V). Neither of these two mutations was detected in DNA from 100 unrelated control subjects. The altered isoleucine residue lies within the third conserved alpha-helical transmembrane domain (M3), which is critical for the formation of the wall of the gap junction pore. Both the deletion of the isoleucine residue 141 and its substitution to valine in the two families could alter the structure of M3, and impair the function of the gap junction. The present data demonstrate that, like mutations in connexin26, mutations in Cx31 can lead to both recessive and dominant forms of non-syndromic deafness.

Abstract
Mast cells have been described extensively in rodents and humans but not in pigs, and the objective of this study was to characterize porcine mast cells by histochemistry and electron microscopy. Carnoy's fluid proved to be a good fixative but fixation with neutral buffered formalin blocked staining of most mast cells. Alcian Blue stained more mast cells than did Toluidine Blue (pH 0.5), although Alcian Blue also stained goblet cells. In pigs, unlike rodents, the Alcian Blue method did not distinguish between mast cells in the intestinal mucosa and those in the connective tissue of the intestinal submucosa, tongue and skin. Mast cells were significantly larger in adult pigs than in piglets; in adult pigs and piglets, mast cells in the intestinal mucosa were significantly larger than those in submucosal connective tissue, and they were more varied in shape in piglets and adults. Granules in mast cells in the intestinal mucosa stained less intensely than those in mast cells in connective tissue of tongue, skin and intestinal submucosa. Mast cells in the connective tissue of the tongue, skin and intestinal submucosa fluoresced strongly when stained with berberine sulphate or with a mixture of berberine sulphate and Acridine Orange, but mast cells in the intestinal mucosa did not. All mast cells reacted positively in an enzyme-histochemical method previously used to detect human tryptase but not in a method previously used to detect human chymase. Mast cells in the medulla of thymus stained similarly to mast cells in the intestinal mucosa. Ultrastructural differences between mast cells were not detected.

Abstract
Acute bracken poisoning and enzootic haematuria are believed to have occurred in cattle in China for a long time. It is only in the past 10 years, however, that these diseases associated with the consumption of bracken ferns have been studied in detail and this paper reviews these recent studies. Based on a large scale survey, both conditions were found to be serious problems with a wide geographical distribution, especially in the mountainous regions of southwest China. Epidemiological and experimental work revealed that two species of bracken ferns, Pteridium aquilinum and Pteridium revolutum, were associated with these diseases, but the latter seems more important in China.

Abstract
Newly hatched chicks were exposed to a 900-Hz tone at 120 dB SPL for 48 hours, then sacrificed, along with unexposed controls, at intervals of 0-15 days following exposure. Examination of the basilar papilla by scanning electron microscopy demonstrated a 32% loss of hair cells within the lesion area with substantial shrinkage of the apical surfaces of the survivors. Within days, the papilla returned to a nearly normal appearance, and new hair cells were seen, but the number of new cells was only a fraction--approximately 22%--of the number lost. Expansion of the apical surfaces of the surviving cells to larger than normal size was a major factor in the recovery of the papilla.
