Abstract
Objective: To analyze immune reconstitution and influencing factors in HIV infected men who have sex with men (MSM) with access to antiviral therapy (ART) in Guangxi Zhuang Autonomous Region (Guangxi) during 2005-2021. Methods: The data were collected from Chinese Disease Prevention and Control Information System. The study subjects were HIV infected MSM with access to the initial ART for ≥24 weeks in Guangxi from 2005 to 2021 and HIV RNA lower than the detection limit within 24 months. The proportion of infected MSM who had immune reconstitution after ART was calculated. Cox proportional hazard regression model was used to analyze the influencing factors of immune reconstitution. Software SPSS 24.0 was used for statistical analysis. Results: A total of 3 200 HIV infected MSM were enrolled, in whom 15.56 % (498/3 200) had no immune reconstitution, 14.78% (473/3 200) had moderate immune reconstitution, and the rate of complete immune reconstitution was 69.66% (2 229/3 200). The M (Q1, Q3) of ART time for immune reconstitution was 12 (5, 27) months. Multivariate Cox proportional risk regression model analysis results showed that compared with those with initial ART at age ≥30 years, WHO clinical stage Ⅲ/Ⅳ illness, baseline BMI <18.50 kg/m2 and baseline CD4+T lymphocyte (CD4) counts <200 cells/µl, HIV infected MSM with initial ART at age <30 years, WHO clinical stageⅠ/Ⅱ illness, baseline BMI≥24.00 kg/m2 and baseline CD4 counts ≥200 cells/µl were more likely to have complete immune reconstitution. Conclusions: In the HIV infected MSM in Guangxi, failures to achieve moderate and complete immune reconstitution were observed. Surveillance and ART regimen should be improved for key populations, such as those with older age and low baseline CD4 counts.

[PMID: 38238130 DOI: 10.1016/j.puhe.2023.11.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 10/27/2023] [Accepted: 11/10/2023] [Indexed: 02/18/2024]
Abstract
OBJECTIVES To assess the prevalence, all-cause mortality and determinants of advanced HIV disease (AHD) or severe immunosuppression (SIS) in the rural-urban communities of Southwestern China. STUDY DESIGN Retrospective cohort study. METHOD Data on HIV/AIDS cases reported in 2005-20 were collected from Case Report System. A binary logistic regression model assessed the risk factors of AHD/SIS prevalence. Survival curves across rural-urban regions were compared using Kaplan-Meier estimates and log-rank tests. Determinants of all-cause mortality were identified using the Cox proportional hazard model. RESULTS Among 14,533 newly diagnosed HIV/AIDS patients, 7497 (51.6%) presented with AHD and 2564 (17.6%) with SIS. Compared with urban patients, rural patients had a higher prevalence of AHD (56.7% vs 40.7%) and SIS (20.1% vs 12.4%), all-cause mortality (AHD 12.3 vs 5.6, SIS 16.3 vs 5.5, per 100 person-years). Their 5-year survival probability (AHD 59.5% vs 77.1%; SIS 54.4% vs 76.3%) and mean survival time (AHD 106.5 vs 140.6 months, SIS 95.3 vs 144.2 months, p < 0.0001) were lower. Rural patients had an increased risk of SIS prevalence (adjusted odds ratios 1.45, 95% confidence interval [CI] 1.28-1.64; p < 0.0001) and mortality of the total cohort (adjusted hazard ratios 1.41, 95% CI 1.29-1.55; p < 0.0001), AHD cohort (1.38, 1.24-1.54; p < 0.0001), and SIS cohort (1.49, 1.23-1.81; p < 0.0001). CONCLUSIONS A high prevalence of AHD/SIS was a severe phenomenon that caused high mortality in rural areas. A regional point-of-care strategy targeting AHD/SIS detection and management is essential for reducing the mortality risk.

Abstract
CFHR5 nephropathy is a type of clinical C3 glomerulopathy, which is a monogenic genetic disease caused by the internal replication of CFHR5 gene, a protein related to the complement regulatory factor H family. The disease seems to be prevalent only in people of Greek Cypriot descent. Because of the special variation of the internal replication of exon 2 and exon 3 of CFHR5 protein in the occurrence of disease, it has had a serious impact on local residents. At present, the mechanism of glomerular damage caused by CFHR5 protein mutations is still unclear. The purpose of this article is to review the clinical research advances of this disease in the past 10 years, including the study of mutant genes, the analysis of mutant proteins and the role of alternative pathways in glomerular injury. It covers the progress in diagnosis and clinical treatment of the disease and looks forward to the future development prospects of its treatment. It is hoped that the recent results will be summarized for the follow-up in-depth study of CFHR5 nephropathy.

Abstract
Objective: To investigate death and attrition in HIV-infected children under initial antiretroviral therapy (ART) and associated factors in Guangxi Zhuang autonomous region. Methods: This retrospective cohort study was conducted in HIV-infected children under initial ART in Guangxi from 2004 to 2019, data from ART information system of National comprehensive AIDS prevention and treatment information system. Cox proportional hazards models were used to assess factors associated with the death and attrition. Results: In 943 HIV-infected children, the overall mortality and attrition rates were 1.00/100 person-years and 0.77/100 person-years, respectively. The mortality and attrition rates within the first year of ART were 3.90/100 person-years and 1.67/100 person-years, respectively. The cumulative survival rate during the first, second, fifth and tenth year after ART was 96.14%, 95.80%, 93.68% and 91.54%, respectively. Multivariate Cox proportional hazards models results showed that being female (aHR=2.00, 95%CI: 1.17-3.40), CD4+T lymphocytes (CD4) counts before ART <200 cells/μl (aHR=2.79, 95%CI: 1.54-5.06), weight-for-age Z score before ART <-2 (aHR=2.38, 95%CI: 1.32-4.26), hemoglobin before ART <80 g/L (aHR=2.47, 95%CI: 1.24-4.92), initial ART with LPV/r (aHR=5.05, 95%CI: 1.15-22.12) were significantly associated with death; being female (aHR=2.23, 95%CI: 1.22-4.07) and initial ART with LPV/r (aHR=2.02, 95%CI: 1.07-3.79) were significantly associated with attrition. Conclusions: The effect of ART in HIV-infected children in Guangxi was better, but the mortality and attrition rates were high within the first year of treatment. It is necessary to strengthen the training in medical staff and health education in HIV-infected children and their parents in order to improve the treatment effect.

Abstract
Objective: To analyze HIV transmission hotspots and characteristics of cross-regional transmission in Guangxi Zhuang autonomous region (Guangxi) based on the molecular network analysis, and provide evidence for optimization of precise AIDS prevention and control strategies. Methods: A total of 5 996 HIV pol sequences sampled from Guangxi between 1997 and 2020 were analyzed together with 165 534 published HIV pol sequences sampled from other regions. HIV-TRACE was used to construct molecular network in a pairwise genetic distance threshold of 0.5%. Results: The proportion of HIV sequences entering the molecular network of HIV transmission hotspots in Guangxi was 31.5% (1 886/5 996). In the molecular network of HIV cross-regional transmission, the links within Guangxi accounted for 51.6% (2 613/5 062), the links between Guangxi and other provinces in China accounted for 48.0% (2 430/5 062), and the links between Guangxi and other countries accounted for 0.4% (19/5 062). The main regions which had cross-regional linked with Guangxi were Guangdong (49.5%, 1 212/2 449), Beijing (17.5%, 430/2 449), Shanghai (6.9%, 168/2 449), Sichuan (5.7%, 140/2 449), Yunnan (4.2%, 102/2 449), Shaanxi (3.8%, 93/2 449), Zhejiang (2.8%, 69/2 449), Hainan (2.0%, 49/2 449), Anhui (1.5%, 37/2 449), Jiangsu (1.3%, 33/2 449), and other regions (each one <1.0%), respectively. The risk factors of entering the molecular network of HIV transmission hotspots in Guangxi included being aged ≥50 years (compared with being aged 25-49 years, aOR=1.68,95%CI:1.46-1.95), males (compared with females, aOR=1.21,95%CI:1.05-1.40), being single (compared with being married, aOR=1.18,95%CI:1.00-1.39), having education level of high school or above (compared with having education level of junior high school or below, aOR=1.21,95%CI:1.04-1.42), acquired HIV through homosexual intercourse (compared with acquired with HIV through heterosexual intercourse, aOR=1.77, 95%CI:1.48-2.12). The risk factors of cross-regional transmission included males (compared with females, aOR=1.74,95%CI:1.13-2.75), having education level of high school or above (compared with having education level of junior high school or below, aOR=1.96,95%CI:1.43-2.69), being freelancer/unemployed/retired (compared with being farmers, aOR=1.50,95%CI:1.07-2.11), acquired HIV through homosexual intercourse (compared with acquired with HIV through heterosexual intercourse, aOR=3.28,95%CI:2.30-4.72). Conclusion: There are HIV transmission hotspots in Guangxi. Guangxi and other provinces in China form a complex cross-regional transmission network. Future studies should carry out social network surveys in high-risk populations inferred from the molecular network analysis for the timely identification of hidden transmission chains and reduction of the second-generation transmission of HIV.

Abstract
OBJECTIVE To investigate the epidemiological characteristics and identify the risk factors of Giardia lamblia infections among patients with colorectal cancer in Henan Province. METHODS A cross-sectional study was performed for questionnaire surveys among colorectal cancer patients in Henan Cancer Hospital during the period from March to July, 2021. Patients' stool samples were collected, and the triosephosphate isomerase (tpi) gene of G. lamblia was amplified in stool samples using nested PCR assay to characterize the parasite genotype. Univariate analysis and multivariate logistic regression analyses were employed to identify the risk factors of G. lamblia infections among colorectal cancer patients. RESULTS A total of 307 colorectal cancer patients were investigated, including 176 males (57.3%) and 131 females (42.7%). PCR assay detected 8.1% [95% confidential interval (CI): (0.056, 0.117)] prevalence of G. lamblia infections among the study subjects, and there was no significant difference in the prevalence between men [9.1%, 95% CI: (0.057, 0.143)] and women [6.9%, 95% CI: (0.037, 0.125)] (χ2 = 0.495, P = 0.482). In addition, there was no age-specific prevalence of G. lamblia infections among the participants (χ2 = 1.534, P = 0.675). Multivariate logistic regression analysis identified use of septic tanks [odds ratio (OR) = 3.336, 95% CI: (1.201, 9.267)], daily use of well water [OR = 3.042, 95% CI: (1.093, 8.465)] and raising livestock [OR = 3.740, 95% CI: (1.154, 12.121)] as risk factors of G. lamblia infections among colorectal cancer patients, and the prevalence of abdominal pain was significantly greater in colorectal cancer patients with G. lamblia infections than in those without infections (P = 0.017). Among the 25 patients with G. lamblia infections, assemblage A was characterized in 24 (96.0%) cases and assemblage B in one case (4.0%). CONCLUSIONS The prevalence of G. lamblia is high among colorectal cancer patients in Henan Province, and assemblage A is the dominant genotype of G. lamblia. Use of septic tanks, daily use of well water and raising livestock are risk factors of G. lamblia infections among patients with colorectal cancer.

Background/Introduction
Prior studies have demonstrated abnormalities of diastolic function are independent predictors of heart failure and all-cause mortality. The optimal way to classify diastolic function has continued to evolve over time, particularly in those with preserved left ventricular ejection fraction. A notable change in the 2016 American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines is that individuals with impaired myocardial relaxation and normal filling pressure can be classified as normal diastolic function.
Purpose
To determine whether the association of diastolic dysfunction with increased risk of all-cause mortality is driven by cardiovascular or non-cardiovascular death. Second, to evaluate if the presence of an impaired myocardial relaxation inflow pattern without other diastolic abnormalities conveys a marker of increased risk.
Methods
This study utilized the Olmsted County Heart Function Study (OCHFS), a well characterized prospective adult community cohort with comprehensive echocardiography between 2001 and 2004 and long-term follow-up. Only individuals with measurable diastolic function were included (n = 1,104). Those with reduced left ventricular ejection fraction, more than moderate valve disease, or a clinical diagnosis of heart failure (n = 52); or indeterminate diastolic function (n = 47) were excluded. Diastolic function was assessed by the current Mayo Clinic diagnostic algorithm (Figure).
Results
A total of 695 individuals were classified as normal, 265 with impaired myocardial relaxation or grade 1 diastolic dysfunction, and 45 with grade 2-3 diastolic dysfunction. Those with diastolic dysfunction were older and had more comorbidities including diabetes, hypertension and coronary disease (Table). There were 264 deaths in the median follow up period of 15.2 years (IQR 14.4 – 18.0), including 173 non-cardiovascular and 81 cardiovascular deaths. Both cardiovascular and non-cardiovascular mortality were associated with the presence and grade of diastolic dysfunction (Table 1). Individuals classified as normal by 2016 ASE/EACVI criteria, but grade 1 by the Mayo algorithm had an increased risk of all-cause mortality after univariate analysis (HR 4.35, 95% CI (3.35, 5.65), p < 0.0001) compared to normal subjects and remained associated after adjustment for age (HR 1.55, 95% CI (1.15, 2.09), p < 0.0001. Subjects with a grade 1 pattern had a higher rate of cardiovascular mortality (ꭕ2 70.1, p < 0.0001).
Conclusions
Individuals with diastolic dysfunction, including those with an impaired relaxation mitral inflow, were at increased risk of mortality, particularly cardiovascular mortality. This study highlights the importance of separating grade 1 diastolic dysfunction from normal in the assessment of diastolic function as it represents a clinically significant risk marker of myocardial disease.

Abstract
Objective: To explore the effects of porcine acellular dermal matrix (ADM) combined with human epidermal stem cells (ESCs) on wound healing of full-thickness skin defect in nude mice. Methods: The morphology of porcine ADM was analyzed by photograph of digital camera, the cell residues in porcine ADM were observed by hematoxylin-eosin (HE) staining, the surface structure of porcine ADM was observed by scanning electron microscope, the secondary structure of porcine ADM was analyzed by infrared spectrometer, the porcine ADM particle size was analyzed by dynamic light scattering particle size analyzer, and the porcine ADM potential was analyzed by nano-particle size potentiometer. The morphology of porcine ADM was observed by inverted fluorescence microscope when it was placed in culture medium for 30 min, 1 d, and 5 d (n=2). The porcine ADM was divided into 5 min group, 10 min group, 20 min group, 30 min group, 60 min group, and 120 min group according to the random number table (the same grouping method below) in static state at normal temperature for the corresponding time to calculate the water absorption by weighing method (n=3). Swiss white mouse embryonic fibroblasts (Fbs) were divided into blank control group (culture medium only), and 50.0 g/L ADM extract group, 37.5 g/L ADM extract group, 25.0 g/L ADM extract group, 12.5 g/L ADM extract group, and 6.5 g/L ADM extract group which were added with the corresponding final concentrations of ADM extract respectively. At post culture hour (PCH) 24, 48, and 72, the cell survival rate was detected by cell counting kit 8 and the cytotoxicity was graded (n=5). The erythrocytes of a 6-week-old male Sprague-Dawley male rat were divided into normal saline group, ultra-pure water group, and 5 mg/mL ADM extract group, 10 mg/mL ADM extract group, and 15 mg/mL ADM extract group which were treated with the corresponding final concentrations of porcine ADM extract respectively. After reaction for 3 h, the absorbance value of hemoglobin was detected by microplate reader to represent the blood compatibility of porcine ADM (n=3). ESCs were isolated and cultured from the discarded prepuce of a 6-year-old healthy boy who was treated in the Department of Urology of the First Affiliated Hospital of Army Medical University (the Third Military Medical University) in July 2020, and then identified by flow cytometry. The porcine ADM particles of composite ESC (hereinafter referred to as ESC/ADM) were constructed by mixed culture. After 3 days of culture, the composite effect of ESC/ADM was observed by HE staining and laser scanning confocal microscope. Thirty-six 7-8-week-old male non-thymic nude mice were divided into phosphate buffer solution (PBS) alone group, ADM alone group, ESC alone group, and ESC/ADM group, with 9 mice in each group, and the wound model of full-thickness skin defect was established. Immediately after injury, the wounds were treated with the corresponding reagents at one time. On post injury day (PID) 1, 7, 11, and 15, the wound healing was observed and the wound healing rate was counted (n=3). On PID 7, the epithelialization of wounds was observed by HE staining and the length of un-epithelialized wound was measured (with this and the following sample numbers of 4). On PID 11, the dermal area and collagen deposition of wounds were observed by Masson staining and the dermal area of wound section was calculated, the number of cells expressing CD49f, a specific marker of ESC, was calculated with immunofluorescence staining, the mRNA expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in ESC after wound transplantation was detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction. Data were statistically analyzed with independent sample t test, one-way analysis of variance, analysis of variance for repeated measurement, and least significant difference t test. Results: The porcine ADM was white particles and composed of reticular structure, with no cells inside, disordered structure, and rough surface. The absorption peak of porcine ADM appeared at the wave numbers of 1 659, 1 549, and 1 239 cm-1, respectively. The main particle size distribution of porcine ADM in solution was 500 to 700 nm, with negative charge on the surface. The morphology of porcine ADM in static state at 30 min and on 1 and 5 d was relatively stable. The water absorption of porcine ADM remained relatively high level in static state from 30 min to 120 min. The cytotoxicity of mouse embryonic Fbs in 6.5 g/L ADM extract group, 12.5 g/L ADM extract group, and 25.0 g/L ADM extract group was grade 1 at PCH 24, and the cytotoxicity of the other groups was 0 grade at each time point. After reaction for 3 h, the absorbance value of hemoglobin of erythrocytes in ultra-pure water group was significantly higher than the values in normal saline group and 15 mg/mL ADM extract group (with t values of 8.14 and 7.96, respectively, P<0.01). After 3 days of culture, the cells of the fourth passage showed pebble-like morphology, with low expression of CD71 and high expression of CD49f, which were identified as ESCs. There was ESC attachment and growth on porcine ADM particles. On PID 1, the wound sizes of nude mice were almost the same in PBS alone group, ADM alone group, ESC alone group, and ESC/ADM group. On PID 7, 11, and 15, the wound contraction of nude mice in each group was observed, especially in ADM alone group, ESC alone group, and ESC/ADM group. On PID 7, the wound healing rates of nude mice in ESC alone group and ESC/ADM group were significantly higher than the rate in PBS alone group (with t values of 2.83 and 4.72 respectively, P<0.05 or P<0.01). On PID 11, the wound healing rate of nude mice in ESC/ADM group was significantly higher than that in PBS alone group (t=4.86, P<0.01). On PID 15, the wound healing rates of nude mice in ADM alone group, ESC alone group, and ESC/ADM group were significantly higher than the rate in PBS alone group (with t values of 2.71, 2.90, and 3.23 respectively, P<0.05). On PID 7, the length of un-epithelialized wound of nude mice in ADM alone group, ESC alone group, and ESC/ADM group was (816±85), (635±66), and (163±32) μm, respectively, which were significantly shorter than (1 199±43) μm in PBS alone group (with t values of 5.69, 10.19, and 27.54 respectively, P<0.01). On PID 11, the dermal areas of wound section of nude mice in ADM alone group, ESC alone group, and ESC/ADM group were significantly larger than the area in PBS alone group (with t values of 27.14, 5.29, and 15.90 respectively, P<0.01); the collagen production of nude mice in ADM alone group and ESC/ADM group was more obvious than that in PBS alone group, and the collagen production of nude mice in ESC alone group and PBS alone group was similar. On PID 11, in the wounds of nude mice in ESC alone group and ESC/ADM group, the cells with positive expression of CD49f were respectively 135±7 and 185±15, and the mRNA expressions of GAPDH were positive; while there were no expressions of CD49f nor mRNA of GAPDH in the wounds of nude mice in PBS alone group and ADM alone group. Conclusions: ESC/ADM particles can promote the wound healing of full-thickness skin defects in nude mice, which may be related to the improved survival rate of ESCs after transplantation and the promotion of dermal structure rearrangement and angiogenesis by ADM.

Abstract
Blastocystis hominis is a common intestinal protozoan parasite. Most individuals with B. hominis infections have no apparent clinical symptoms; however, a few patients, notably those with co-infections or impaired immune system function may present abdominal pain, diarrhea, nausea, vomiting, and even death. This paper reviews the co-infections of B. hominis and other pathogens and comorbidity of B. hominis infections and other diseases, so as to provide insights into the management of B. hominis infections.

Abstract
OBJECTIVE To investigate the prevalence and risk factors of Blastocystis hominis infections among AIDS patients in Nanchang City. METHODS A cross-sectional questionnaire survey was conducted among AIDS patients in Nanchang City during the period between May and September, 2016. B. hominis infection was detected in patients'stool samples using a PCR assay, and the CD4+ T cell count was measured in subjects'blood samples. In addition, the risk factors of B. hominis infection in AIDS patients were identified using univariate and multivariate logistic regression analyses. RESULTS A survey was conducted in Nanchang City from May to September 2016. A total of 505 AIDS patients were investigated, and the prevalence of B. hominis infection was 4.16%. Univariate analysis revealed that B. hominis infection correlated with the occupation (χ2 = 8.595, P = 0.049), education level (χ2 = 14.494, P = 0.001), type of daily drinking water (χ2 = 10.750, P = 0.020), root of HIV infections (χ2 = 8.755, P = 0.026) and receiving anti-HIV therapy (χ2 = 23.083, P = 0.001) among AIDS patients, and multivariate logistic regression analysis identified daily direct drinking of tap water as a risk factor of B. hominis infections [odds ratio (OR) = 7.988, 95% confidential interval (CI): (1.160, 55.004)] and anti-HIV therapy as a protective factor of B. hominis infection [OR = 0.183, 95% CI: (0.049, 0.685)]. CONCLUSIONS The prevalence of B. hominis is 4.16% among AIDS patients in Nanchang City. Daily direct drinking of tap water is a risk factor, and anti-HIV therapy is a protective factor of B. hominis infection among AIDS patients living in Nanchang City.

Abstract
OBJECTIVE The aim of this study was to explore the role of micro ribonucleic acid (miR)-15b in steroid-induced osteonecrosis of the femoral head (SONFH) and its potential mechanism. PATIENTS AND METHODS Bone marrow tissues were collected from 5 patients with glucocorticoid (GC)-induced ONFH (GC-ONFH, GC group) and 5 patients with secondary ONFH (control group) undergoing total hip replacement in our hospital from July 2016 to August 2017. Subsequently, bone marrow mesenchymal stem cells (BMSCs) were separated from bone marrow extracted and cultured in vitro. Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) assay was used to detect differentially expressed miRNAs in BMSCs of patients in GC group and control group. BMSCs were treated with different concentrations of GC. Next, the effect of GC on tmiR-15b expression level was detected via qRT-PCR. Alizarin red staining assay was performed to evaluate the effect of miR-15b on osteogenic differentiation of BMSCs. Meanwhile, the potential targets of miR-15b were predicted using bioinformatics software and validated through luciferase reporter gene assay, respectively. Additionally, Western blotting was conducted to determine the effect of miR-15b on the protein expression of the transforming growth factor beta (TGF-β) signaling pathway. RESULTS Flow cytometry demonstrated that the proportion of cluster of differentiation 44 (CD44)-positive cells was 99.7%, while that of CD45-positive cells was only 0.17% in cultured BMSCs. This suggested that the purity of BMSCs was relatively high. QRT-PCR assay indicated that the expression level of miR-15b declined significantly in BMSCs of GC group when compared with control group (p<0.01). The osteogenic differentiation capacity of BMSCs was significantly strengthened in GC group compared with control group (p<0.01). Subsequent qRT-PCR assay revealed that GC down-regulated the expression level of miR-15b in a dose-dependent manner. Besides, the osteogenic differentiation capacity of cells was remarkably strengthened in miR-15b mimic treatment group when compared with control group (p<0.01). Bioinformatics software (TargetScan) predicted that drosophila mothers against decapentaplegic protein 7 (Smad7) might be a potential target of miR-15b, which was indicated by luciferase reporter gene assay. In comparison with control group, miR-15b mimic treatment group exhibited significantly down-regulated protein expression level of Smad7, increased expression level of phosphorylated (p)-Smad2/3 and up-regulated messenger RNA (mRNA) expression level of runt-related transcription factor 2 (Runx2). However, the protein expression level of Smad7 and p-Smad2/3 and the mRNA expression level of Runx2 exhibited opposite trends in miR-15b inhibitor treatment group. CONCLUSIONS MiR-15b relieves SONFH by targeting Smad7 and repressing osteogenic differentiation of BMSCs.

Abstract
Objective: To investigate the consistency of Velum, Oropharygneal, Tongue base, Epiglottis (VOTE) scores between two surgeons with similar clinical experience in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different degree of disease, and to analyze the influencing factors leading to the difference in score. Methods: This was a cross-sectional study. 64 preoperative drug-induced sleep endoscopy (DISE) videos of OSAHS patients during December 2014 to July 2018, from Nanfang Hospital, Southern Medical University were analyzed. The VOTE score was assessed single-blind by two similar experienced surgeons, and the Kappa value between the two scorers was calculated by the third researcher. According to the characteristics of the case, Fisher's exact test or chi-square test method was used to further explore the factors that influenced the consistency. Results: Sixty-four patients were divided into four groups according to the severity of the disease, including mild (7 cases), moderate (30 cases), severe(18 cases), and extremely severe (9 cases). The scores evaluated between two researchers were analysed for consistency. For mild patients, the two scorers were completely consistent in the configuration and degree of obstruction in the velum and epiglottis (Kappa=1). There was no agreement on whether obstruction or not, obstructed configuration, obstructed degree of the oropharynx and tongue base, and presence of velum and epiglottis obstruction. For moderate patients, the two scorers had a good consistency in the configuration and degree of the velum (0.61≤Kappa≤0.80), and there was no consistency in the evaluation of the degree of tongue base and epiglottis (P>0.05). The consistency of the remaining obstructed conditions in the four planes was generally or moderate (0.21≤Kappa≤0.60). For patients with severe OSAHS, the two raters were completely consistent in the evaluation of palatopharyngeal and epiglottic planes for the presence of obstruction, but there was no consistency in the degree of obstruction. Although the degree of obstruction in the oropharyngeal plane can be assessed with good consistency, the consistency of whether the plane was blocked or not was generally not high. In the assessment of other obstructive conditions in the four planes of severe patients, the agreement between the two scorers was moderate or generally. For extremely severe patients, the two scorers were completely consistent in the evaluation of the velum obstruction, but there was no consistency in the degree of obstruction of the oropharynx and tongue base, and the obstruction configuration and degree of the epiglottis. The evaluation of other obstructed conditions in the four planes is good or moderate. Among the patients with severe OSAHS, the difference in the assessment of obstruction of the oropharynx was associated with tonsil size (P<0.05). Conclusion: When physicians with similar clinical experience scored VOTE, the consistency of whether the velum and oropharyngeal planes are obstructed is related to the severity of the disease. Better consistency is observed among more severe OSAHS patients. The reason for the poor consistency of the oropharyngeal plane in severe OSAHS patients OSAHS is due to the difference of the tonsils size. For severe OSAHS patients with small tonsils, the assessment of whether the oropharynx is obstructed should be more cautious.

Abstract
PURPOSE To explore the morphological and microstructural changes of grey and white matter in the patients of thyroid-associated ophthalmopathy (TAO). METHODS Twenty-five TAO patients and 25 well-matched healthy controls were recruited. Structural T1- and diffusion-weighted magnetic resonance imaging data were analyzed using voxel-based morphometry and voxel-based analysis of diffusion tensor imaging. RESULTS Compared with healthy controls, TAO group showed significantly decreased grey matter volume in the brain region of the right middle frontal gyrus. Meanwhile, TAO group showed significantly decreased fractional anisotropy (FA), but increased mean, axial and radial diffusivities in the brain regions of the right superior occipital gyrus, middle occipital gyrus and cuneus in TAO group. In addition, the FA value in significant brain regions showed a positive correlation with visual acuity (r = 0.456, P = 0.025) and a negative correlation with disease duration (r = - 0.609, P = 0.003). CONCLUSION Significant morphological and microstructural abnormalities in areas corresponding to known functional deficits of vision and cognition could be found in TAO patients. These results extended our understanding of neural relationships with TAO.

Abstract
OBJECTIVE To investigate the prevalence and risk factors of Blastocystis infections among primary school students in Jiangjin District, Chongqing City. METHODS A cross-sectional questionnaire survey was conducted among students sampled from a primary school in Jiangjin District, Chongqing City on April, 2018, and their stool samples were collected for microscopic examinations, in vitro culture and PCR assays to analyze the prevalence of Blastocystis infections and subtype of the parasite. In addition, the risk factors of Blastocystis infections among primary school students were identified using univariate analysis and multivariate logistic regression analysis. RESULTS A total of 466 primary students were surveyed, and the subjects had a mean age of (9.81±1.66) years and included 236 males (50.64%) and 230 females (49.36%). The prevalence of Blastocystis infections was 15.24% (71/466) among the study students, and there was no significance difference in the prevalence between male and fe- male students (16.52% vs. 13.91%; χ2 = 0.616, P = 0.433). In addition, there was a significant difference in the prevalence of Blastocystis infections among grade 1 (6.35%, 4/63), grade 2 (5.17%, 3/58), grade 3 (21.74%, 15/69), grade 4 (25.30%, 21/83), grade 5 (10.19%, 11/108) and grade 6 students (20.00%, 17/85) (χ2 = 15.410, P = 0.009). There were four Blastocystis subtypes characterized (ST1, ST3, ST6 and ST7), in which ST6 was the most common subtype (45.07%, 32/71), followed by ST3 (25.35%, 18/71). Multivariate logistic regression analysis revealed that minority ethnicity [odds ratio (OR) = 4.259, 95% confidential inter- val (CI) : (1.161, 15.621)] and low maternal education level (primary school and below) [OR = 9.038, 95% CI: (1.125, 72.642)] were identified as risk factors of Blastocystis infection among primary school students in Jiangjin District, Chongqing City. CONCLUSIONS There is a high prevalence of Blastocystis infections detected among primary school students in Jiangjin District, Chongqing City, and ST6 and ST3 are predominant subtypes. Minority ethnicity and low maternal education level (primary school and below) are risk factors for Blastocystis infections in primary school students.

Abstract
AIM To evaluate the performance of T2 mapping histograms at the extraocular muscles (EOMs) in predicting the response to glucocorticoid therapy in the patients with active and moderate-severe thyroid-associated ophthalmopathy (TAO). MATERIALS AND METHODS Thirty active and moderate-severe TAO patients (responsive group, n=20; unresponsive group, n=10) were enrolled, and evaluated using T2 mapping before treatment. Histogram parameters (mean, median, max, min, 10th, 90th percentiles, skewness, and kurtosis) of T2 relaxation time (T2RT) at the EOMs for each orbit, and clinical variables (age, sex, disease duration, anti-thyroid treatment, smoking habit, pre-treatment thyroid function, thyrotrophin receptor antibody, diplopia presence, activity and severity scores) were collected and compared between groups. Logistic regression and receiver operating characteristic (ROC) curve analyses were used to assess the predictive value of identified independent variables for treatment response. RESULTS The responsive group showed significantly shorter disease duration (p=0.003), while higher T2RTmin than unresponsive group (p<0.001). Multivariate analysis showed that T2RTmin and disease duration were independent predictors for responsive TAOs. ROC curve analyses indicated that setting a cut-off value of ≥54.3 for T2RTmin demonstrated the optimal predicting specificity for responsive TAOs (100%), while a combination of T2RTmin ≥54.3 and disease duration ≤4.5 showed optimal predicting efficiency and sensitivity (area under the curve, 0.820; sensitivity, 65%). CONCLUSIONS Histogram analysis can help to exhibit the heterogeneity of T2RT at the EOMs. T2RTmin, together with disease duration may be the promising marker for predicting response to glucocorticoid therapy in the patients with active and moderate-severe TAO.

Abstract
OBJECTIVE To detect the potential of microRNA-492 (miR-492) as a diagnostic biomarker of acute myocardial infarction (AMI) in the acute phase. PATIENTS AND METHODS A total of 100 AMI patients and 100 controls (non-AMI patients with chest pain) were retrospectively analyzed. Blood samples were collected at 0, 6, 12, and 24 h after admission, followed by detection of the serum miR-492 level. Serum levels of cTnI and creatine kinase-MB (CK-MB) in AMI patients were examined by enzyme-linked immunosorbent assay (ELISA). The potential relationship between miR-492 level with cTnI and CK-MB levels was analyzed by Pearson correlation test. Moreover, diagnostic value of miR-492 was assessed by depicting receiver operating characteristic (ROC) curves. RESULTS Serum level of miR-492 achieved the peak at 6 h after admission, which was time-dependently reduced at 12 h and 24 h. Serum levels of cTnI and CK-MB were higher in AMI patients than those of controls. However, miR-492 level achieved the peak before cTnI and CK-MB increased to the highest levels. MiR-492 level was positively correlated to cTnI and CK-MB levels. ROC curves verified the diagnostic value of miR-492 in AMI (AUC=0.8621, 95% CI=0.8129-0.9112, sensitivity=80%, specificity=75%). CONCLUSIONS Serum level of miR-492 remarkably increases in the acute phase of AMI, which may be used as an effective biomarker for diagnosing AMI.

Abstract
OBJECTIVE Recent evidence shows that gastric adenocarcinoma predictive long intergenic noncoding RNA (GAPLINC) acts as a critical role in the proliferation and metastasis in several tumors. We aimed to explore the expression pattern, function, and potential mechanism of GAPLINC in glioblastoma multiforme (GBM). PATIENTS AND METHODS The expression levels of GAPLINC and its clinical significance were determined by analyzing TCGA datasets. RT-PCR was performed to detect the levels of GAPLINC and miR-331-3p. CCK-8, colony formation, EdU assays, wound healing assay and transwell invasion assay were performed to analyze the effect of GAPLINC on GBM behaviors. MiRNAs that may interact with GAPLINC were predicted using StarBase and RegRNA 2.0. A luciferase reporter assay was used to detect the targeting effect of GAPLINC on miR-331-3p. RESULTS We found that GAPLINC expression was significantly up-regulated in both GBM tissues and cell lines. The overexpression of GAPLINC was associated with shorter overall survival and disease-free survival. Functional assays indicated that GAPLINC silencing suppressed GBM cells proliferation, migration, and invasion, and promoted apoptosis. In the mechanism, we found that GAPLINC acted as a competing endogenous RNA to sponge miR-331-3p and knockdown of GAPLINC promoted the expression of miR-331-3p. CONCLUSIONS Our findings suggested that GAPLINC served as an oncogenic lncRNA in GBM through negative modulation of miR-331-3p, providing a novel treatment targeting for GBM.

Abstract
Objective: To explore influence on physical development of children aged 18 months from HIV-positive mothers for prevention mother to child transmission of HIV (PMTCT) in Guangxi Zhuang autonomous region, and provide evidence for the improvement PMTCT program. Methods: This retrospective case control study was conducted in 554 HIV negative infants aged 18 months whose HIV positive mothers had received PMTCT services reported through PMTCT system database from January 1, 2010 to December 31, 2017 and 1 109 healthy infants born in 2017, whose mothers were healthy, in Lingshan, Luzhai, and Hengxian counties, ranking top three counties with high HIV infection prevalence, in Guangxi. PMTCT data and physical development data such as height, weight and head circumference of children aged 18 months were collected. The physical dysplasia in the infants was defined as at least one of the three main indicators of height, weight and head circumference below the normal range. Results: The number of HIV-positive mother and their infants in the case group were 667 and 554 respectively, and the PMTCT rates were 91.15% (608/667) and 96.57% (535/554) respectively. HIV positive rate, mortality rate and mother to child transmission rate of the infants aged 18 months were 1.44% (8/554), 3.07% (17/554) and 1.91% (8/418) respectively, and the physical examination results of the infants aged 18 months showed that the physical dysplasia rate was 30.51% (169/554). Among the 1 109 infants in the control group, the physical dysplasia rate was 9.83% (109/1 109). The difference between the case group and the control group was significant (P<0.01). Conclusion: The PMTCT rates of HIV positive mother and their children were more than 90.00%, respectively. However, poor physical development rate of infants aged 18 months were more than 30.00%. The possible influence of PMTCT on physical development of the infants aged 18 months of HIV positive mother's needs to be further studied.

Impact of trauma centre capacity and volume on the mortality risk of incoming new admissions. BMJ Mil Health 2020; 168:212-217.

Abstract
INTRODUCTION Trauma centre capacity and surge volume may affect decisions on where to transport a critically injured patient and whether to bypass the closest facility. Our hypothesis was that overcrowding and high patient acuity would contribute to increase the mortality risk for incoming admissions. METHODS For a 6-year period, we merged and cross-correlated our institutional trauma registry with a database on Trauma Resuscitation Unit (TRU) patient admissions, movement and discharges, with average capacity of 12 trauma bays. The outcomes of overall hospital and 24 hours mortality for new trauma admissions (NEW) were assessed by multivariate logistic regression. RESULTS There were 42 003 (mean=7000/year) admissions having complete data sets, with 36 354 (87%) patients who were primary trauma admissions, age ≥18 and survival ≥15 min. In the logistic regression model for the entire cohort, NEW admission hospital mortality was only associated with NEW admission age and prehospital Glasgow Coma Scale (GCS) and Shock Index (SI) (all p<0.05). When TRU occupancy reached ≥16 patients, the factors associated with increased NEW admission hospital mortality were existing patients (TRU >1 hour) with SI ≥0.9, recent admissions (TRU ≤1 hour) with age ≥65, NEW admission age and prehospital GCS and SI (all p<0.05). CONCLUSION The mortality of incoming patients is not impacted by routine trauma centre overcapacity. In conditions of severe overcrowding, the number of admitted patients with shock physiology and a recent surge of elderly/debilitated patients may influence the mortality risk of a new trauma admission.

Abstract
AIM To evaluate the relationship between dipeptidyl peptidase-4 inhibitor (DPP4i) treatment and chronic rhinosinusitis (CRS) in diabetic patients. METHODS We used the Longitudinal Health Insurance Database for this population-based and population-matched cohort design study. Chi-square and Wilcoxon rank-sum tests were used to evaluate the association between categorical and continuous variables, respectively. The Kaplan-Meier method with the log-rank test was used to estimate the risk of CRS and DPP4i users. RESULTS A total of 6198 diabetic patients were included in this cohort study. DPP4i users had a lower risk of developing CRS. The risk of CRS was significantly lower in women, patients with a Diabetes Complications Severity Index score higher than 4, patients with comorbidities, and patients with higher cumulative defined daily dose in the DPP4i group. CONCLUSION The results of our study demonstrate that the use of DPP4i treatment could decrease CRS risk in diabetic patients in Taiwan.

Abstract
S-Adenosyl-l-methionine-dependent methyltransferases (SAMMTases) modulate important cellular and metabolic activities in both prokaryotes and eukaryotes. Here, we functionally characterized an SAMMTase gene (MTase15) in the migratory brown planthopper (BPH), Nilaparvata lugens, which is the most notorious rice pest in Asia. The cDNA sequence of MTase15 is 2764 nt in length with an open reading frame of 1218 nt encoding 405 amino acid residues. Quantitative real-time PCR analysis showed that MTase15 was readily detected from egg to adult stages and extensively distributed in various body parts of adult females and males, with slightly high levels in ovary and testis, respectively. In addition, MTase15 was transcriptionally regulated by the insulin signalling pathway in BPH. RNA-interference-mediated knockdown of MTase15 (dsMtase15) resulted in deficiencies in vitellogenin synthesis and oogenesis, and female infertility. Males with Mtase15 knockdown retained the capability of producing sperms with normal viability, but less sperm was transferred to wild-type (wt) females during copulation, and eggs laid by these wt females arrested embryogenesis. These findings not only assign a functional role to MTase15, but also provide a link between the insulin signalling pathway and epigenetic regulation in BPH reproduction.

Abstract
Objective:To analyze the related factors of VOTE score for drug-induced endoscopy(DISE) in patients with obstructive sleep apnea (OSA). Method:Fifty-four OSA patients, diagnosed by polysomnograph, underwent surgical treatment from Nov 2014 to Dec 2016 in our hospital. All patients underwent drug induced sleep endoscope, and then the collapse of pharyngeal space was evaluated. We analyzed the related factors with VOTE score. Result:The occlusion rates were significant statistical different in different spaces of 54 OSA patients undergoing DISE(P=0.000, velum 98.15%, oropharynx 81.48%, tongue base 40.47%, and epiglottis 11.11% respectively). The rateand of tongue base collapsing was related with Mallampatis(P<0.05) and Friedman stage(P<0.05). The VOTE score was weakly related with Friedman stage(r=0.297, P<0.05), medium related with BMI(r=0.376, P<0.05), AHI(r=0.312, P<0.05) and lowest SpO2(r=0.376, P<0.01). Conclusion:In the VOTE scoring system for DISE, the rate of collapse in tongue base was related with Mallampatis and Friedman stage. The VOTE score was medium related with BMI, AHI and Lowest SpO2, mild related with Friedman stage.

Abstract
Objective: To analyze the change trend of HIV genetic subtypes and compare the first CD(4)(+)T cell counts of newly diagnosed HIV infected patients in Liuzhou from 1998 to 2012, and provide a reference for AIDS prevention and control. Methods: Newly diagnosed HIV-infected patients from 1998 to 2012 in Liuzhou were selected through national HIV/ADIS comprehensive response information management system. Their plasma samples were used for RNA gene extraction, amplification, sequencing and genotyping. Coharan-Armitage trend test was used to analyze the ratio trend of genetic subtypes and phylogenetic clusters of HIV and Wilcoxon Rank Sum Test was used to compare the first CD(4)(+)T cell counts (CD(4)) of the different subtype HIV infected patients. Results: A total of 1 877 newly diagnosed HIV infected patients were included in the study. From 1998 to 2012, the proportions of CRF01_AE and CRF01_AE (Cluster 1) increased from 78.4% (76/97) to 91.5% (1 441/1 574), from 63.9% (62/97) to 74.0% (1 164/1 574), and the proportion of CRF07_BC decreased from 17.5% (17/97) to 4.6% (72/1 574), respectively (Z=4.632, P<0.001; Z=2.455, P=0.014; Z=-5.943, P<0.001). The median and interquartile range of the first CD(4) of the patients infected with subtype CRF01_AE (Cluster 1), CRF01_AE (Cluster 2), CRF07_BC and CRF08_BC were 230 (83-375), 215 (48-351), 365 (254-503) and 334 (206-479) cell/μl, respectively. The first CD(4) levels of the patients infected with subtype CRF01_AE (Cluster 1) or CRF01_AE (Cluster 2) were significantly lower than those of CRF07_BC (Z=-4.795, P<0.001; Z=-4.238, P<0.001). Conclusion: The genetic subtypes of HIV were mainly CRF01_AE in newly diagnosed HIV-infected patients and this subtype proportion was in increase and the first CD(4) levels of the patients were low in Liuzhou during 1998 to 2012.

Abstract
The Fracture Risk Assessment Tool (FRAX) has been used universally for the purpose of fracture risk assessment. However, the predictive capacity of FRAX for autoimmune diseases remains inconclusive. This study aimed to compare the applicability of FRAX for autoimmune disease patients. This retrospective study recruited rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and primary Sjögren syndrome (pSS) patients with bone mineral density (BMD) tests. Patients with any osteoporotic fractures were identified. Taiwan-specific FRAX with and without BMD were then calculated. In total, 802 patients (451 RA, 233 SLE and 118 pSS) were enrolled in this study. The cumulative incidences of osteoporotic fractures in the RA, SLE and pSS patients were 43.0%, 29.2% and 33.1%, respectively. For those with a previous osteoporotic fracture, T-scores were classified as low bone mass. Overall, the patients' 10-year probability of major fracture risk by FRAX without BMD was 15.8%, which then increased to 20.3% after incorporation of BMD measurement. When analyzed by disease group, the fracture risk in RA patients was accurately predicted by FRAX. In contrast, current FRAX, either with or without BMD measurement, underestimated the fracture risk both in SLE and pSS patients, even after stratification by age and glucocorticoid treatment. For pSS patients with major osteoporotic fractures, FRAX risks imputed by RA were comparable to major osteoporotic fracture risks of RA patients. Current FRAX accurately predicted fracture probability in RA patients, but not in SLE and pSS patients. RA-imputed FRAX risk scores could be used as a temporary substitute for SLE and pSS patients.

Abstract
BACKGROUND Osteoporosis is a global disease burden for aging society. The role of quantitative ultrasound (QUS) in the prediction for osteoporosis in a dose-response manner is hardly addressed. AIM We aimed to show the dose-response of QUS measurement in the prediction for osteoporosis by a community-based study. DESIGN A prospective cohort study. METHODS Participants were recruited between 2000 and 2004. Demographic data and heel QUS measurement were collected at baseline. Diagnosis of osteoporosis was ascertained by the follow-up of this cohort over time. In order to reduce the imbalance of baseline characteristics in the observational study, we applied propensity score by using proportional odds regression analysis to match the quintiles of QUS T-score. RESULTS A total of 44 957 subjects composed of 17 678 men (39.3%) and 27 279 women (69.7%) were recruited. After adjustments for propensity score, an increase in one unit of QUB T-score led to 7% reduction in the risk for osteoporosis [adjusted odds ratio (OR) = 0.93, 95% confidence interval (CI): 0.89-0.96, P < 0.0001]. Higher quintile of QUS T-score yielded a lower risk of osteoporosis with a gradient relationship [OR: 0.82 (95%CI: 0.72-0.92); OR: 0.81 (95%CI: 0.71-0.91); OR: 0.77 (95%CI: 0.68-0.87) and OR: 0.76 (95%CI: 0.67-0.86)] from the second to highest quintile opposed to first quintile (P < 0.0001). The cumulative incidence of osteoporosis was higher in the lower quintile during follow-up (log-rank test, P < 0.001). CONCLUSION QUS is an independent predictor for osteoporosis in a dose-response manner using a large population-based cohort. Due to the lower cost and portability of QUS measurement, the pre-screening for osteoporosis by QUS can be considered in the area with limited resources can be a feasible and alternative method.

Abstract
Lupus nephritis (LN) is the leading cause of mortality in lupus patients. This study aimed to investigate the treatment outcome and renal histological risk factors of LN in a tertiary referral center. Between 2006 and 2017, a retrospective observational study enrolled 148 biopsy-proven LN patients. After propensity score matching, 75 cases were included for further analysis. The classification and scoring of LN were assessed according to the International Society of Nephrology/Renal Pathology Society. Treatment response was evaluated by daily urine protein and urinalysis at two years after commencing induction treatment and the development of end-stage renal disease (ESRD). In total, 50.7% patients achieved complete remission (CR) or partial remission (PR), while 49.3% patients were categorized as nonresponders. Therapeutic responses in terms of CR/PR rates were associated with Systemic Lupus Erythematosus Disease Activity Index scores (odds ratio (OR): 1.34, 95% confidence interval (CI): 1.12-1.60, p = 0.001). Moreover, higher baseline creatinine levels (hazard ratio (HR): 2.10, 95% CI: 1.29-3.40, p = 0.003), higher renal activity index (HR: 1.30, 95% CI: 1.07-1.58, p = 0.008) and chronicity index (HR: 1.40, 95% CI: 1.06-1.85, p = 0.017) predicted ESRD. Among pathological scores, cellular crescents (HR: 4.42, 95% CI: 1.01-19.38, p = 0.049) and fibrous crescents (HR: 5.93, 95% CI: 1.41-24.92, p = 0.015) were independent risk factors for ESRD. In conclusion, higher lupus activity was a good prognostic marker for renal remission. Renal histology was predictive of ESRD. Large-scale prospective studies are required to verify the efficacy of mycophenolate in combination with azathioprine or cyclosporine in LN patients.

Abstract
Accumulating studies have suggested that microRNA play a part in regulating multiple cellular processes, such as cell proliferation, apoptosis, the cell cycle, and embryo development. This study explored the effects of miR-101-2 on donor cell physiological status and the development of Holstein cow somatic cell nuclear transfer (SCNT) embryos in vitro. Holstein cow bovine fetal fibroblasts (BFF) overexpressing miR-101-2 were used as donor cells to perform SCNT; then, cleavage rate, blastocyst rate, inner cell mass-to-trophectoderm ratio, and the expression of some development- and apoptosis-related genes in different groups were analyzed. The miR-101-2 suppressed the expression of inhibitor of growth protein 3 (ING3) at mRNA and protein levels, expedited cell proliferation, and decreased apoptosis in BFF, suggesting that ING3, a target gene of miR-101-2, is a potential player in this process. Moreover, by utilizing donor cells overexpressing miR-101-2, the development of bovine SCNT embryos in vitro was significantly enhanced; the apoptotic rate in SCNT blastocysts was reduced, and the inner cell mass-to-trophectoderm ratio and SOX2, POU5F1, and BCL2L1 expression significantly increased, whereas BAX and ING3 expression decreased. Collectively, these findings suggest that miR-101-2 promotes BFF proliferation and vitality, reduces their apoptosis, and improves the early development of SCNT embryos.

Abstract
Background The stability of Alzheimer's disease (AD) biomarkers in plasma, measured by immunomagnetic reduction (IMR) after long-term storage at −80°C, has not been established before. Method Ninety-nine human plasma samples from 53 normal controls (NCs), 5 patients with amnestic mild cognitive impairment (aMCI), and 41 AD patients were collected. Each plasma sample was aliquoted and stored as single-use aliquots at −80°C. The baseline measurements for Aβ1–40, Aβ1–42, and total Tau protein (T-Tau) concentrations for each sample were done within 3 months of blood draw by IMR. They are referred to as baseline concentrations. A separate aliquot from each sample was assayed with IMR to assess the stability of the measured analytes during storage at −80°C between 1.1 and 5.4 years. This is referred to as a repeated result. Results IMR shows that plasma levels of Aβ1–40 and Aβ1–42 exhibit stability over 5-year storage at −80°C and that plasma levels of T-Tau are less stable (approximately 1.5 years). Conclusion Although the measured concentrations of T-Tau in human plasma may alter during storage, the diagnostic utility of the results are only slightly affected when the product of Aβ1–42 and T-Tau concentrations are used. The results show that the overall agreement between baseline and repeated measurements in the ability of discriminating NCs from aMCI/AD patients is higher than 80%.

Abstract
We report a 49-year-old woman who presented with a hypertensive crisis and acute heart failure and reduced left ventricular systolic function. An abdominal ultrasonography revealed a huge lobulated heterogeneous mass at the lower pole of the right kidney and a mass over the left suprarenal area, which were further delineated by magnetic resonance imaging. The patient underwent laparoscopic right radical nephrectomy and left adrenalectomy. Histopathological analysis confirmed the diagnoses of clear cell renal cell carcinoma of the right kidney with metastasis to the lung; and atypical pheochromocytoma of the left adrenal gland. Target therapy was initiated, which resulted in stabilization of the patient's tumors and the recovery of her heart function. To avoid a delayed diagnosis and catastrophic outcome, clinicians should consider such rare causes of acute decompensated heart failure.

SLC27A2 regulates miR-411 to affect chemo-resistance in ovarian cancer. Neoplasma 2018; 65:915-924.

Abstract
Although platinum-based chemotherapies have long been used as standard treatment in ovarian cancer, cisplatin resistance is a major problem that restricts its use. Herein, we investigate the biological function of SLC27A2 and its underlying mechanisms in regulating chemo-resistance in ovarian cancer. The findings show that SLC27A2 down-regulation in primary ovarian cancer tissues correlates with chemo-resistance and poor patient survival in our patient cohort. Significantly, we demonstrate that up-regulation of SLC27A2 by lentivirus-mediated p-SLC27A2 sensitizes ovarian cancer cells to cisplatin in vitro and in vivo via apoptosis. Mechanistic investigation reveals that miR-411 is the most strikingly over-expressed gene in response to ectopic expression of SLC27A2, but under-expressed in recurrent ovarian cancer tissues. Lower miR-411 expression contributes to ovarian cancer chemo-resistance in vitro and in vivo. Furthermore, SLC27A2 directly binds specific sites in the miR-411 promoter region and promoter activity decreases after mutation of putative SLC27A2-binding sites. This indicates that SLC27A2 is required for the transcriptional induction of miR-411. The luciferase assays also confirm that miR-411 directly targets ABCG2 in ovarian cancer, and overall findings establish the SLC27A2-miR-411-ABCG2 pathway in the regulation of ovarian cancer chemo-resistance with potential therapeutic applications.

Abstract
Objective: To understand the dynamic variation of BMI and influencing factors among HIV/AIDS patients receiving highly active anti-retroviral therapy (HAART) in Liuzhou, Guangxi Zhuang Autonomous Region (Guangxi). Methods: HIV/AIDS patients receiving HAART for the first time since 1 January 2013 were selected. Data on BMI was analyzed among patients receiving HAART at baseline,6 months and 12 months after treatment. By using the general linear model repeated measures of analysis of variance, BMI dynamic variations and influencing factors were described and analyzed. Results: The average BMI of 2 871 patients at baseline, 6th months and 12th months appeared as (20.65±3.32), (20.87±3.22) and (21.18±3.20), respectively, with differences all statistically significant (F=18.86, P<0.001). BMI were increasing over time with treatments (F=37.25, P<0.001). Main influencing factors were noticed as: age, sex, marital status, baseline data of CD(4)(+)T cells and the WHO classification on clinical stages. Conclusions: Higher proportion of BMI malnutrition counts was seen among patients before receiving HAART in Liuzhou. BMI of the patients that were on HAART seemed being influenced by many factors. It is necessary to select appropriate treatment protocols on different patients so as to improve the nutritional status of the patients.

Abstract
Objective: To discuss the relationship between lingual tonsil hypertrophy and laryngopharyngeal reflux. Methods: Ninety-two patients who received throat surgery in Nanfang Hospital between October 2015 and October 2016 were enrolled. Twenty-six healthy volunteers were recruited as normal controls. All participants were assessed with the reflux finding score(RFS) and the size of lingual tonsils were evaluated using a clinical grading system proposed by Friedman under electronic laryngoscope. The score of reflux symptom index(RSI), personal history and medical history were gathered. Biopsy specimens of lingual tonsils were taken from all participants for the immunohistochemical stain of pepsin.SPSS 19.0 software was used for statistical analysis. Results: There were 46.2% (12/26) pepsin-positive and 53.8% (14/26) pepsin-negative volunteers in normal controls. There were 87.0% (80/92) pepsin-positive and 13.0% (12/92) pepsin-negative patients in study group. The severity of lingual tonsil hypertrophy and expression intensity of pepsin in patients were significantly higher in volunteers (Z=-3.636, Z=-5.273, P<0.01). The severity of lingual tonsil hypertrophy was positively associated with the pepsin level in patients (r=0.556, P<0.01). The patients with pepsin-positive expression showed significant correlation between lingual tonsil hypertrophy and the positive rate of RSI and RFS (r=0.258, r=0.225, P<0.05). Analysis of correlated factors indicated that lingual tonsil hypertrophy was associated with smoking (χ(2)=8.502, P<0.05). Conclusions: The expression of pepsin can be detected in lingual tonsil tissues. The lingual tonsil hypertrophy is closely related to laryngopharyngeal reflux.

Abstract
Objective:To compare the differences of the sites of airway obstruction in OSAHS patients between awake and sleep state by using the VOTE classification system. Method:Forty OSAHS patients diagnosed by PSG underwent awake Müller's maneuver and drug-induced sleep endoscopy (DISE). Video and compare the observation. Its findings were described using the VOTE classification system which include the following features: level, degree and configuration of obstruction. Associations were analyzed between different degrees of obstruction, BMI, AHI, minimal SaO₂ and average SaO₂. Result:Our patients had 52.5% complete velum collapse and 30.0% complete oropharyngeal lateral wall collapse in awake Müller's maneuver. In DISE, airway closure of 95.0% cases related to velum occurred collapse in concentric configuration, and 90.0% cases showed completely obstructive. We found that 60.0% complete oropharyngeal lateral wall collapse and 17.5% complete tongue base collapse. There was a significant difference in the VOTE scores between DISE and awake Müller's maneuver, and the VOTE scores of DISE were higher in all levels (P<0.05). No association was found between degrees of obstruction, AHI, BMI, minimal SaO2 and average SaO₂ in Müller's maneuver (P>0.05). Complete velum collapse was just significantly associated with AHI and minimal SaO₂ in DISE (P<0.05). Conclusion:The VOTE scores of DISE were higher than awake Müller's maneuver, reflected by more obstructive levels and severe degree. The difference between different degrees of obstruction, BMI, AHI, minimal SaO₂ and average SaO₂ was not significant.

Abstract
OBJECTIVES We evaluated whether and how the effects of risk factors on periodontal disease (PD) were modified by measurement errors using community periodontal index (CPI) and loss attachment (LA) in the community-based survey. METHODS A pilot validation study was performed to estimate the rates of false negative and false positive for both CPI and LA in 31 subjects from different regions using measurements from 12 well-trained dentists and a senior periodontist as a gold standard. Afterward, a Taiwanese nationwide survey was conducted by enrolling 3,860 participants to estimate the effect of each risk factor on PD calibrated with both sensitivity and specificity of two indices. RESULTS The values obtained for the sensitivity to false-positive ratio for CPI ranged widely from 1.12 to 7.71, indicating regional variation in both errors. The calibrated adjusted odds ratio for smoking vs non-smoking was higher than the uncalibrated odds ratio for PD defined by CPI (2.75 (2.01, 3.77) vs 2.02 (1.63, 2.52)) and LA (3.85 (2.44, 6.13) vs 1.93 (1.47, 2.54)) scores. Similar underestimation was noted for other risk factors. CONCLUSION The effects of risk factors on PD measured using CPI and LA in a large population-based survey were underestimated without correcting for measurement errors.

Abstract
OBJECTIVE The aim of this study is to analyze the effect of light deprivation on the expression of vascular endothelial growth factor (VEGF) and neovascularization in the retina of neonatal rats. MATERIALS AND METHODS Thirty-six neonatal SD rats (male and female) were used in this study. These rats were numbered randomly and assigned into 3 groups (12 rats in each group), ie. 10-day group (routine feeding after birth, eyeball enucleation on 10th day), 14-day group (routine feeding after birth, eyeball enucleation on 14th day) and light deprivation group (routine feeding within 1st week after birth, feeding with light deprivation within 2nd week after birth, eyeball enucleation on 14th day). The expression level of VEGF mRNA was measured by RT-PCR, and the percentage of the retinal vascular area was calculated by PAS staining, and the number of vascular endothelial cells was counted with a microscope in a double-blind manner. RESULTS It was found that the expression levels of VEGF mRNA and the number of vascular endothelial cells in 10-day group and light deprivation group were significantly higher than 14-day group (p < 0.05), while the difference between the 10-day group and light deprivation group was not significant. The percentage of retinal vascular area in the 10-day group and light deprivation group was significantly lower than 14-day group (p < 0.05), while the difference between the 10-day group and the light deprivation group was not significant. CONCLUSIONS The light deprivation delayed the growth of neovessels in the retina.

Abstract
OBJECTIVE P27Kip1 is the one of the negative regulators of the cell cycle that plays an important role in regulating cell cycle and inhibiting cell proliferation by restraining cell in G1 phase. P27Kip1 downregulation maybe related to the occurrence of oral squamous cell carcinoma (OSCC). It was found that miR-155 significantly upregulated in OSCC tissue. Bioinformatics analysis revealed that miR-155 may bind with the 3'-UTR of p27Kip1. This study investigated the role of miR-155 in regulating p27Kip1 and affecting Tca8113 cell proliferation, cycle, and apoptosis. PATIENTS AND METHODS A total of 46 cases of OSCC patients received treatment in our hospital were enrolled to obtain tumor tissue. Another 25 normal oral mucosa samples were selected as control to detect the relationship between miR-155 and p27Kip1 expressions. Dual luciferase assay was adopted to confirm the targeted relationship between miR-155 and p27Kip1. Flow cytometry was applied to test cell apoptosis and cell cycle. CCK-8 assay was used to evaluate cell proliferation. Caspase-3 activity was detected by spectrophotometry. RESULTS MiR-155 upregulated, while p27Kip1 declined in OSCC tissue compared with normal oral mucosa. Their expressions were related to TNM stage. MiR-155 targeted suppressed p27Kip1 expression. MiR-155 mimic and/or pEGFP-p27Kip1 transfection obviously declined p27Kip1 expression, blocked cell cycle in G1 phase, reduced cell proliferation, enhanced Caspase-3 activity, and increased cell apoptosis in Tca8113 cells. CONCLUSIONS MiR-155 increased, while p27Kip1 reduced in OSCC tissue. Inhibition of miR-155 upregulated p27Kip1 expression, blocked cell cycle in G1 phase, weakened cell proliferation, and induced cell apoptosis.

Impact of mTOR Inhibitors on Cancer Development in Kidney Transplantation Recipients: A Population-Based Study. Transplant Proc 2016; 48:900-4. [PMID: 27234763 DOI: 10.1016/j.transproceed.2016.01.017] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2015] [Revised: 01/07/2016] [Accepted: 01/21/2016] [Indexed: 10/21/2022]
Abstract
BACKGROUND The mammalian target of rapamycin (mTOR) inhibitor is an immunosuppressive drug used in kidney transplantation. Whether the mTOR inhibitor is associated with reduced risk of cancer development and mortality after kidney transplantation is controversial. METHODS We conducted a nationwide population-based study. Patients who did not have malignancy history and received kidney transplantation between 2010 and 2013 were enrolled. Recipients who had mTOR inhibitors (n = 430) for more than 30 days comprised the study group; 1720 recipients who did not have mTOR inhibitors comprised the control group. The primary outcome is the development of cancer after kidney transplantation. These patients were followed until the first-time admission with diagnosis of cancer, death, or the end of 2014. A Cox proportional-hazard model was used to determine the risk of cancer development and all-cause mortality. RESULTS During the 35-month median duration of observation, there were 16 and 61 patients with cancer development in the study group and the control group, respectively. The cancer incidence was 12.8 and 12.4 per 1000 person-years. There were 10 and 135 mortality cases, with the incidence rate of 7.8 and 26.9 per 1000 person-years. After multivariable adjustment, the mTOR inhibitors users were not associated with reduced risk of new cancer development as compared with control (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.46-1.60; P = .63), nor risk of all-cause mortality (HR, 0.70; 95% CI, 0.33-1.46; P = .34). CONCLUSIONS The use of mTOR inhibitors was not associated with a reduction in the risk of cancer development and all-cause mortality in kidney transplantation recipients.

Abstract
Objective: To investigate the relationship between ambulatory arterial stiffness index (AASI) and left ventricular mass index (LVMI) in the elderly hypertensive patients. Methods: This study population consisted of 332 elderly hypertensive patients, who hospitalized in our department from January 2012 to December 2014.AASI was calculated from 24 h ambulatory BP monitoring recordings and LVMI from echocardiography examination.According to the median value of AASI, patients were divided to less than the AASI median group (low AASI group) and equal to or above the AASI median group (high AASI group). Differences between two groups were evaluated using the Student's t-test and Chi-square test.Univariate association was assessed by the Pearson correlation analyses.Multivariate linear regression models were performed to analyze the correlation between AASI and LVMI. Results: LVMI was significantly higher in high AASI group compared with low AASI group ( (115.91±21.36) g/m2 vs.(104.11±17.24) g/m2,P=0.008). Pearson correlation analyses showed that AASI and 24 h pulse pressure were positively correlated to LVMI (r=0.332, P<0.001; r=0.169, P=0.002). In multivariate linear regression model, AASI(β=44.48, P<0.001), LDL-C(β=-5.97, P<0.001) and UA (β=0.02, P=0.045)showed significant association with LVMI. Conclusion: AASI independently associated with LVMI, and AASI might be one predictor of left ventricular hypertrophy in hospitalized elderly hypertensive patients.
