ABSTRACT

In this study, untargeted metabolomics was conducted using the liquid chromatography-tandem mass spectrometry(LC-MS/MS) technique to analyze the potential biomarkers in the plasma of mice with heart failure with preserved ejection fraction(HFpEF) induced by a high-fat diet(HFD) and nitric oxide synthase inhibitor(Nω-nitro-L-arginine methyl ester hydrochloride, L-NAME) and explore the pharmacological effects and mechanism of Jiming Powder in improving HFpEF. Male C57BL/6N mice aged eight weeks were randomly assigned to a control group, a model group, an empagliflozin(10 mg·kg~(-1)·d~(-1)) group, and high-and low-dose Jiming Powder(14.3 and 7.15 g·kg~(-1)·d~(-1)) groups. Mice in the control group were fed on a low-fat diet, and mice in the model group and groups with drug intervention were fed on a high-fat diet. All mice had free access to water, with water in the model group and Jiming Powder groups being supplemented with L-NAME(0.5 g·L~(-1)). Drugs were administered on the first day of modeling, and 15 weeks later, blood pressure and cardiac function of the mice in each group were measured. Heart tissues were collected for hematoxylin-eosin(HE) staining to observe pathological changes and Masson's staining to observe myocardial collagen deposition. Untargeted metabolomics analysis was performed on the plasma collected from mice in each group, and metabolic pathway analysis was conducted using MetaboAnalyst 5.0. The results showed that the blood pressure was significantly lower and the myocardial concentric hypertrophy and left ventricular diastolic dysfunction were significantly improved in both the high-dose and low-dose Jiming Powder groups as compared with those in the model group. HE and Masson staining showed that both high-dose and low-dose Jiming Powder significantly alleviated myocardial fibrosis. In the metabolomics experiment, 23 potential biomarkers were identified and eight strongly correlated metabolic pathways were enriched, including linoleic acid metabolism, histidine metabolism, alpha-linolenic acid metabolism, glycerophospholipid metabolism, purine metabolism, porphyrin and chlorophyll metabolism, arachidonic acid metabolism, and pyrimidine metabolism. The study confirmed the pharmacological effects of Jiming Powder in lowering blood pressure and ameliorating HFpEF and revealed the mechanism of Jiming Powder using the metabolomics technique, providing experimental evidence for the clinical application of Jiming Powder in treating HFpEF and a new perspective for advancing and developing TCM therapy for HFpEF.

ABSTRACT

Objective:To explore the clinical characteristics of acquired immunodeficiency syndrome (AIDS) complicated with nontuberculous mycobacteria (NTM) disease.Methods:The clinical data of 190 patients with AIDS complicated with NTM disease diagnosed by Shanghai Public Health Clinical Center, Fudan University from January 1, 2019 to December 31, 2021 were analyzed retrospectively. NTM diseases were divided into disseminated NTM disease group and non-disseminated NTM disease group. The independent sample t test, Mann Whitney U test and chi-square test were used for statistical analysis. Results:The 190 patients with AIDS complicated with NTM disease included 182 males and eight females. The age was (42±13) years old, and the first hospital stay was 15(6, 26) days. Pneumocystis carinii pneumonia was the most common co-infection in 12.1%(23/190) of patients, 87 cases (45.8%) were disseminated NTM disease. The clinical symptoms of patients were common in fever (55.8%(106/190)), cough (50.0%(95/190)), and expectoration (28.9%(55/190)). The proportions of fatigue (31.0%(27/87) vs 7.8%(8/103)), poor appetite (21.8%(19/87) vs 10.7%(11/103)) in the AIDS patients with disseminated NTM disease group were higher than those in the non-disseminated NTM disease group, and the differences were statistically significant ( χ2=16.99, P<0.001 and χ2=4.42, P=0.036, respectively). There was no significant difference in the proportions of deaths between AIDS patients with disseminated NTM disease and those without disseminated NTM disease (17.2%(15/87) vs 12.6%(13/103), χ2=0.80, P=0.371). The most common NTM species was Mycobacterium avium (67.1%(49/190)), followed by Mycobacterium kansasii (15.1%(11/190)). Hemoglobin ((90.3±23.9) g/L vs (110.1±24.2) g/L), albumin ((29.7±5.5) g/L vs (34.7±5.6) g/L), CD4 + T lymphocyte count (11(5, 30)/μL vs 52(16, 96)/μL) and CD8 + T lymphocyte count ((362±320)/μL vs (496±352)/μL) in the disseminated NTM disease group were lower than those in non-disseminated NTM disease group ( t=-5.63, P<0.001; t=-6.18, P<0.001; Z=-5.90, P<0.001; and t=-2.73, P=0.007, respectively), while procalcitonin (0.24(0.10, 0.77) μg/L vs 0.10 (0.04, 0.51) μg/L) was higher than that in the non-disseminated NTM disease group ( Z=-3.09, P=0.002), with statistical significance. The most common imaging features were lung patch and strip shadow (67.4%(128/190)). Conclusions:The most common type of AIDS patients complicated with NTM disease is disseminated NTM disease, and Mycobacterium avium is the most common NTM species. The clinical manifestations (fatigue, anorexia) and laboratory tests (hemoglobin, albumin, procalcitonin, CD4 + T lymphocyte count, CD8 + T lymphocyte count) of AIDS patients with disseminated NTM disease and non-disseminated NTM disease are different, while the prognosis is not significantly different.

ABSTRACT

Objective:To analyze the clinical and epidemiological characteristics and changing trends of acquired immunodeficiency syndrome (AIDS)-associated talaromycosis in Shanghai City.Methods:The clinical data of patients with AIDS-associated talaromycosis hospitalized at Shanghai Public Health Clinical Center, Fudan University from Janauary 1, 2014 to December 31, 2021 were collected. The medical information included age, gender, place of origin, clinical symptoms, imaging manifestations, blood routine test, CD4 + T lymphocyte count. The chi-square test or Fisher exact probability test was used for statistical analysis. Univariate logistic regression was used to analyze the related risk factors for death. Results:From 2014 to 2021, a total of 12 165 AIDS patients were admitted, including 169 (1.4%) AIDS-assiociated talaromycosis patients. The proportions of AIDS-associated talaromycosis in AIDS inpatients from 2014 to 2021 were 1.8%(21/1 149), 1.1%(14/1 307), 1.3%(19/1 446), 0.9%(15/1 610), 1.2%(20/1 626), 1.2%(22/1 778), 1.7%(28/1 624) and 1.8%(30/1 625), respectively, which had not changed much. There was no statistically significant difference in the proportion of AIDS-associated talaromycosis in AIDS inpatients in different years ( χ2=9.50, P=0.218). Among the 169 patients, 157 cases (92.9%) were male, with the age of (37.9±12.2) years, and 35 were from Jiangxi Province, 31 from Shanghai Municipality, 29 from Zhejiang Province, 17 from Anhui Province, 14 from Fujian Province, 11 from Jiangsu Province, eight from Hunan Province, four from Heilongjiang Province, three cases each from Guangxi Zhuang Autonomous Region, Guizhou Province and Henan Province, two cases each from Hubei Province, Shandong Province, Shanxi Province, Yunnan Province and Guangdong Province, and one case from Chongqing Municipality. Patients from non-traditional endemic areas did not find a clear history of living in traditional endemic areas. Of 169 patients, 143(84.6%) cases had fever, 73(43.2%) had respiratory symptoms, and 26(15.4%) had rash during the course of the disease, 147(87.0%) had pulmonary imaging abnormalities, 94(55.6%) were complicated by other pathogens, and 44(26.0%) had hepatosplenomegaly, 137(81.1%) had CD4 + T lymphocyte count <50/μL. Twenty-three patients died, with the total fatality rate of 13.6%. The overall mortality rate showed a downward trend year by year. There was a statistically significant difference in the case fatality rate of AIDS-associated talaromycosis in different years (Fisher exact probability test, P=0.046). The result of univariate logistic regression model showed that patients with platelet count<50×10 9/L had an increased risk of death (odds ratio ( OR)=3.33, 95% confidence interval ( CI) 1.13 to 9.81, P=0.029). Conclusions:The overall change of AIDS-associated talaromycosis inpatients in Shanghai is not significant, while the prevalence rate has increased slightly in recent two years. The case fatality rate is declining year by year. The proportions of patients without a history of living in or traveling to epidemic areas and without rash as the first manifestation are high, and the main clinical manifestation is multi-system damage. Patients with platelet count<50×10 9/L have an increased risk of death.

ABSTRACT

AIM: To evaluate the changes of retinal microvascular density in patients with sellar region tumor, and its correlation with the damage to visual field, and to explore its application value in evaluating optic nerve injury of those patients.METHODS: Cross-sectional study. A total of 157 patients(292 eyes)with sellar region tumor, including 82 cases(152 eyes)of pituitary adenoma and 75 cases(140 eyes)of craniopharyngioma, were selected from neurosurgery department and ophthalmology department of Beijing Tiantan Hospital, Capital Medical University between October 2018 and May 2022. A total of 90 people(180 eyes)during the same period, including the family members of patients, students and staff in Beijing Tiantan Hospital, Capital Medical University were collected as control group. All participants underwent optical coherence tomography angiography(OCTA)examination. The changes of retinal microvascular density and its correlation with visual field parameters were compared between the two groups.RESULTS: In patients with sellar region tumor, the radial peripapillary capillary(RPC)and superficial retinal capillary plexus(SRCP)density were significantly lower than that in the control group [50.81%(46.49%, 53.49%)vs. 52.78%(50.73%, 54.51%)and 50.57%(48.13%, 52.73%)vs. 51.63%(49.78%, 53.02%), all P<0.05]. The RPC density in the craniopharyngioma group was lower than that in the pituitary adenoma group [49.71%(44.33%, 53.14%)vs. 51.37%(47.42%, 53.95%), P<0.05]. The MD, PSD and VFI of the sellar region tumor group were -4.33(-12.22, -1.85)dB, 3.37(1.91, 8.82)dB and 92%(65%, 97%)respectively. RPC density of patients with sellar region tumor was positively correlated with MD and VFI, and was negatively correlated with PSD. The SRCP density of each quadrant was positively correlated with MD, and was positively correlated with VFI except Para-T and it was negatively correlated with PSD(all P<0.05).CONCLUSION: Retinal microvascular changes were present in patients with sellar region tumor. Lower vessel density indicates more severe damage to visual field. In the clinic, visual field examinations combined with OCTA were helpful to find the optic nerve injury of patients.

ABSTRACT

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.

ABSTRACT

As the disease with high morbidity and mortality in the world, heart failure affects the development of human society. Due to its complicated pathology and limited treatment options, it is urgent to discover new disease targets and develop new treatment strategies. As innate immune cells accompanied by the evolution of heart failure, macrophages play an important role in cardiac homeostasis and stress. In recent years, the role of macrophages in the heart has attracted more and more attention as a potential target for heart failure intervention, and the research on cardiac macrophages has made important progress. Traditional Chinese medicine(TCM) has significant effects on regulating inflammatory response, treating heart failure, and maintaining homeostasis. In this article, researches on the functions of cardiac macrophages and application of TCM were reviewed from the source and classification of cardiac macrophages and the relationship of macrophages and cardiac inflammation, myocardial fibrosis, cardiac angiogenesis, and cardiac electrical conduction, which provided a basis for further basic research and clinical applications.

ABSTRACT

AIM:To investigate the factors affecting patients with post traumatic infectious endophthalmitis(PTIE)relieving from blindness.METHODS: A retrospective study was conducted on 169 patients(169 eyes)with PTIE from January 2010 to December 2020 in the department of ophthalmology, the Affiliated Hospital of Nantong University. After treatment of intravitreal injection of antibiotics(IVIA)and/or pars plana vitrectomy(PPV), the patients were divided into the getting rid of blindness group(103 eyes)and unilateral blindness group(66 eyes)according to the last follow-up of best correct visual acuity(BCVA)≥0.05. The factors affecting the patients to get rid of blindness were analyzed.RESULTS: The rate of relieving from blindness was 53.5%. Univariate analysis showed that BCVA before treatment ≥ hand movement, no retinal detachment, fundus grade of endophthalmitis < grade 3 and no strong virulence of infected microorganisms were beneficial for patients to get rid of blindness(P<0.05). Multivariate Logistic regression analysis identified that BCVA before treatment ≥ hand movement(OR=0.253, 95%CI: 0.108-0.592)and no retinal detachment(OR=0.241, 95%CI: 0.103-0.564)were favorable factors for patient to get rid of blindness.CONCLUSION: Better BCVA before treatment, no retinal detachment, endophthalmitis fundus grade < 3, and no strong virulence of infected microorganisms are favorable factors for patients with PTIE to get rid of blindness finally.

ABSTRACT

Objective:To revise the 2017 classification of irreducible intertrochanteric fractures and summarize reduction techniques of 2021 classification.Methods:A retrospective analysis was conducted of the 17 patients with irreducible intertrochanteric fracture who had been treated at Department of Orthopaedic Surgery, The Ninth People's Hospital of Shanghai, Shanghai Jiaotong University School of Medicine from January 2015 to December 2019. They were 7 males and 10 females, with an age of (73.2 ± 16.1) years. On the basis of 2017 classification, the irreducible intertrochanteric fractures were classified into 2 types in the present 2021 classification. Type Ⅰ were interlocking fractures which were further classified into 3 subtypes: type ⅠA were sagittal interlocking ones (7 cases), type ⅠB greater trochanter interlocking ones (one case) and type ⅠC lesser trochanter interlocking ones (one case). Type Ⅱ were separating fractures which were further classified into 4 subtypes: type ⅡA were sagittal separating ones (4 cases), type ⅡB coronal separating ones (one case), type ⅡC rotational separating ones(one case) and type ⅡD complete separating ones (2 cases). All patients were treated by closed reduction and intramedullary nailing with different reduction strategies corresponding to their fracture types (application of ejector rods, clamps or prying techniques, etc.). A total of 132 patients with reducible femoral intertrochanteric fracture who had been admitted during the same period were selected as the control group. The fracture reduction time, intraoperative blood loss and Harris hip score at the last follow-up were compared between the 2 groups.Results:The 2 groups were comparable because there was no significant difference in their preoperative general data ( P>0.05). Type ⅠA accounted for the highest proportion of irreducible intertrochanteric fractures [41.3% (7/17)], followed by type ⅡA [23.6% (4/17)]. The fracture reduction time [(44.6 ± 6.7) min] in the irreducible group was significantly longer than that in the control group [(39.2 ± 9.6) min] ( P<0.05). There was no significant difference in intraoperative blood loss or Harris hip score at the last follow-up between the 2 groups ( P>0.05). Conclusions:Compared with the "2017 classification" , the "2021 classification" is more concise and easy to remember, and can directly prompt the corresponding proper fracture reduction techniques. The patients with irreducible intertrochanteric fracture using proper reduction techniques can obtain functional recovery similar to that in the patients with reducible intertrochanteric fracture after reduction and fixation.

ABSTRACT

Objective:To explore the characteristics of BCR-ABL1 kinase domain mutations in imatinib-resistant chronic myelogenous leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) patients from Northeast China and their impact on prognosis. Methods:The clinical data of 252 CML patients and 49 Ph + ALL patients who were admitted to the First Hospital of Jilin University from January 2013 to October 2018 were retrospectively analyzed. The samples of bone marrow or peripheral blood were collected from patients when imatinib treatment was not effective. Nested polymerase chain reaction (PCR) was used to amplify the BCR-ABL1 kinase domain, and Sequencing Analysis v5.4 software was used to analyze the mutation of BCR-ABL1 kinase domain. Patients were followed up for 6-48 months, and the survival analysis was performed. Results:Among 252 CML patients, the mutations in ABL1 kinase domain were found in 57 patients (22.6%), including 25 patients in the chronic phase, 21 patients in the accelerated phase and 11 patients in the blast crisis; 50 patients had 20 types of single point mutation, and the most common mutation types were E255K (16.0%, 8/50), T315I (14.0%, 7/50), M244V (8.0%, 4/50) and G250E (8.0%, 4/50), which were all concentrated in the P-loop and C-helix domains; 7 patients had double mutations; patients with multiple mutations had the worst prognosis, with a median overall survival (OS) time of 3.2 months. Among 49 Ph + ALL patients, 17 cases (34.7%) were positive for mutations in the BCR-ABL1 kinase domain, 14 patients had 12 types of single point mutation, and 3 patients had multiple mutations; the median OS time of patients with multiple mutations, mutations located in the P-loop and C-helix domains and mutations located in the other domains was 2.0, 8.0 and 18.0 months, and the difference in OS among the three groups was statistically significant ( P < 0.01). Conclusions:Among the imatinib-resistant CML and Ph + ALL patients from Northeast China, point mutations in the P-loop and C-helix domains are most commonly found. Multiple mutations, mutations in the P-loop and C-helix domains are related to the poor prognosis of the patients.

ABSTRACT

Objective@#To evaluate the effect of high-intensity interval somatosensory training combined with neuromuscular acupoint electrical stimulation on blood glucose and motor function among patients with type 2 diabetes mellitus (T2DM), so as to provide insights into prevention of daily life disability among T2DM patients.@*Methods@#T2DM patients treated in Zhejiang Hospital during the period from January 2019 to October 2021 were enrolled and randomly assigned into four groups. Patients in the K group received Kinect somatosensory interaction technology-assisted high-intensity interval training, patients in the N group received neuromuscular acupoint electrical stimulation, and patients in the KN group received high-intensity interval somatosensory training combined with neuromuscular acupoint electrical stimulation, while patients in the C group were given no interventions. The 2 h postprandial plasma glucose and glycated haemoglobin (HbA1c) levels were measured prior to interventions and 4 and 12 weeks post-interventions, and seven physical fitness tests were performed. The blood glucose levels and motor activity were compared among four groups using generalized estimating equations to evaluate the effectiveness of interventions.@*Results@#Totally 199 T2DM patients were enrolled, including 51 patients in the KN group, 49 patients in the K group, 52 patients in the N group and 47 patients in the C group. There were no significant differences in gender, age, course of disease, duration of daily exercises, waist-to-hip ratio, vital capacity or maximal oxygen uptake among the four groups prior to interventions (all P>0.05). There were time-group interaction effects in blood glucose and exercise parameters among the four groups post-interventions (all P>0.05), with the largest changes seen in the KN group. The HbA1c, 2 h postprandial plasma glucose, 2.4 m standing and detour test and back scratch test results reduced by 17.06%, 27.01%, 36.52% and 20.94% 12 weeks post-interventions as compared to those prior to interventions, while 2 min stepping test, 30 s sit-ups, 30 s loading and elbow flexion test, 6 min walking test and sit and reach test results increased by 18.85%, 34.69%, 15.41%, 7.22% and 112.37%, respectively.@*Conclusion@#High-intensity interval somatosensory training combined with neuromuscular acupoint electrical stimulation may improve the blood glucose and motor activity among patients with T2DM.

ABSTRACT

ObjectiveTo understand the infection of AIDS, syphilis, and gonorrhea in men who have sex with men (MSM), and the factors influencing the acceptance of gonorrhea testing in Dehong Dai Jingpo Autonomous Prefecture (Dehong Prefecture), Yunnan Province. MethodsAcross-sectional survey was conducted to describe and analyze the acceptance of AIDS, syphilis, and gonorrhea testing among MSM tracked in Dehong Prefecture in 2018. ResultsA total of 385 MSM were included in the analysis, with a 100.0% HIV and syphilis testing rate. The HIV antibody positivity rate was 10.6% (41/385) and the positivity rate of syphilis antibody was 14.8%(57/385). Only 30.4% of the subjects were willing to test for gonorrhea, and 13.7%(16/117)of them were test positive. Further multifactorial analysis revealed that local MSM and syphilis co-infected individuals were more likely to be tested for gonorrhea (aOR=2.48, 95%CI=1.33-4.65, P=0.004; aOR=2.59, 95%CI=1.43-4.71, P=0.002). ConclusionThe positive rates of AIDS, syphilis and gonorrhea in MSM population in Dehong Prefecture are relatively high. Integrated interventions of STD/AIDS and gonorrhoea detection should be strengthened.

ABSTRACT

Objective@#To analyze the effect of the peer education intervention model on improving adolescent knowledge, attitudes, and behavior among primary and secondary school students, so as to provide a basis for exploring adolescent based health education methods.@*Methods@#A group of students from grades 4-5 and 7-8 were selected from two primary schools and two middle schools in a district of Chongqing. The sample was divided into an intervention group (n=685) and a control group (n=821), and the intervention group received peer education for one year. Basic information related to the pre and post intervention, and data regarding knowledge, attitudes, and behavior were investigated using a basic situation questionnaire and an adolescent knowledge attitudes behavior questionnaire that were designed by the research group.@*Results@#The results obtained after the intervention showed that the scores of adolescent knowledge attitudes behavior and the total scores of the intervention group increased from (10.00±6.39) (39.19±5.79) (28.69±4.24) and (77.89±12.66) to (15.65±5.87) (42.06±5.95) (29.95±4.05) and (87.66±12.93), and the difference was statistically significant (P<0.01). After the intervention, increasing of adolescent knowledge attitudes behavior and the total scores of the intervention group were (5.64±5.61) (2.87±6.72) (1.26±4.55) (9.77±11.91), respectively, which were higher than those of the control group [(4.42±5.15) (2.08±5.84) (0.86±4.24) (7.36±10.70)]. Except for adolescent behavior, increasing of other scores were statistically significant (t=-4.39,-2.40,-1.73,-4.09,P<0.05).@*Conclusion@#Peer education shows certain effects on improving adolescent knowledge and positive attitudes, although similar effect on adolescent behavior needs further study.

ABSTRACT

Objective@#To understand the health literacy level and its influencing factors among middle school students in Chongqing, and to provide a basis for health promotion.@*Methods@#Using stratified cluster random sampling and a self-designed questionnaire, we conducted a survey among 8 449 junior and senior high school students from four districts and counties in Chongqing municipality from November to December 2019.@*Results@#The attainment rates of total health literacy, functional health literacy, interactive health literacy, and critical health literacy among middle school students in Chongqing were 67.96%, 75.12%, 50.24%, and 72.21%, respectively. Among the 12 factors, low rates were observed in health decision-making, reasonable nutrition, and communication (41.52%, 46.09% and 62.18%, respectively). After controlling for related confounding factors, the results of the multivariate Logistic regression analysis indicated that the following factors affected the total health literacy of middle school students: the investigated region (OR=1.20); school segment (OR=1.35); relationship with mother (OR=1.52); relationship with teacher (OR=2.20); number of close friends (OR=1.68); and health education course (OR=1.52) (P<0.05).@*Conclusion@#The health literacy level of middle school students in Chongqing is relatively low. Therefore, it is necessary to focus on improving interactive health literacy in order to promote the healthy development of middle school students.

ABSTRACT

Objective:To investigate the correlation between variations in mitochondrial DNA (mtDNA) control region (D-loop) and keloids.Methods:A total of 216 patients with keloids were collected from Department of Dermatology, the First Affiliated Hospital of Kunming Medical University from 2016 to 2019. Total DNA was extracted from peripheral blood samples of all the patients, as well as keloid tissues and perilesional normal skin tissues of 25 patients with keloids. Peripheral blood samples were collected from 299 health checkup examinees without keloids in Health Examination Center, the Affiliated Hospital of Yunnan University, who served as controls. PCR amplification and Sanger sequencing were performed on the mtDNA D-loop region, and mutation sites in each sample were analyzed by comparisons with the revised Cambridge Reference Sequence (rCRS) . Haplogroups were assigned in the 2 groups by using Phylotree-mtDNA tree Build 17. Mutations in the mtDNA D-loop region were compared among keloid tissues, perilesional normal skin tissues and peripheral blood samples. A median-joining network was constructed via network 5.0 software. Binary logistic regression analysis was performed to investigate the correlation between haplogroup frequencies and the occurrence of keloids, and chi-square, t and t′ tests were used to analyze clinical data. Results:Among the 216 patients with keloids, variations in mtDNA D-loop region were classified into 10 haplogroups, including A, B, D, R9, G, M*, M7, M8, M9 and N9, with the haplogroups R9 and M9 showing the highest (21.3%, 46/216) and lowest (0.9%, 2/216) frequencies respectively. The frequencies of haplogroups M7 ( P=0.040, OR=0.248, 95% CI: 0.066 - 0.937) and N9 ( P=0.048, OR=0.191, 95% CI: 0.037-0.986) were significantly lower in the patients with keloids than in the controls. The median-joining network plot showed that the distribution pattern of the haplogroup M7 differed between the patients with keloids and controls. Significantly less number of lesional sites and younger age of onset were observed in the patients with haplogroup M7 compared with those with non-M7 haplogroups ( P=0.000 1, 0.045, respectively) . Conclusion:The haplogroup M7 is correlated with the occurrence of keloids, and may be a potential protective factor for keloid formation.

ABSTRACT

Objective:To investigate the diagnostic performance of Xpert Mycobacterium tuberculosis/rifampin (Xpert MTB/RIF) assay for pulmonary tuberculosis (TB) in patients with acquired immunodeficiency syndrome (AIDS). Methods:Clinical data of 226 patients with AIDS and suspected pulmonary TB in Shanghai Public Health Clinical Center, Fudan University from July 2017 to November 2019 were retrospectively analyzed. Fluorescence staining microscopy of sputum smear, BACTEC MGIT 960 liquid culture (or Roche solid culture) and Xpert MTB/RIF assay were implemented respectively. The sensitivity and specificity of Xpert MTB/RIF in the diagnosis of Mycobacterium tuberculosis (MTB) infection and rifampin resistance were analyzed. Results:Totally 226 patients of suspected pulmonary TB were enrolled. There were 94(41.6%) patients had positive mycobacterium culture, in which 51 (54.3%) were MTB and 43 (45.7%) were nontuberculous mycobacteria (NTM). Using the positive MTB culture of sputum and mycobacterial protein from BCG of Rm 0.64 in electrophoresis (MPB64) as reference standard, the sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis were 72.6%(95% confidence interval ( CI) 66.7%-78.4%) and 97.1% (95% CI 95.0%-99.3%), respectively. The sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis in patients with positive sputum smear were 76.7%(95% CI 67.7%-85.8%) and 90.0(95% CI 83.6%-96.5%), respectively. The sensitivity and specificity of Xpert MTB/RIF assay for MTB diagnosis in patients with negative sputum smear were 50.0%(95% CI 41.8%-58.2%)and 99.3%(95% CI 97.9%-100.0%), respectively. With phenotypic resistance as reference standard, the sensitivity and specificity of Xpert MTB/RIF assay for rifampicin resistance were 75.0% and 100.0%, respectively. Conclusion:Among AIDS patients, the performance of Xpert MTB/RIF assay for pulmonary TB diagnosis is pretty good and could differentiate MTB from NTM rapidly, which has good application value.

ABSTRACT

Chronical hyperuricemia, a severe metabolic disease characterized by increased serum uric acid, urea nitrogen, and creatinine, has a positive correlation with the risks of gouty arthritis, diabetes, hypertension, and kidney damage. Abnormal purine metabolism and reduced uric acid excretion are the major causes of hyperuricemia, which, thus, points to a potential strategy of preventing from or delaying the progress of hyperuricemia-related diseases and its complications by effectively controlling the serum uric acid level. Increasing evidence has revealed that Chinese medicines alleviate hyperuricemia through regulating intestinal flora, which plays a pivotal role in regulating metabolites, including uric acid level. The disease treatment with traditional Chinese medicine is based on syndrome differentiation, and Chinese medicines often have multiple effects and a wide range of targets. In this review, we summarized the anti-hyperuricemia effects and mechanisms of active compounds in Chinese medicines, single Chinese medicinal herbs, and Chinese medicinal prescriptions in regulating the uric acid level via intestinal flora and metabolites, which will be helpful for further study and application of Chinese medicines in hyperuricemia treatment.

ABSTRACT

Objective:To investigate the clinical manifestations, imaging findings, characteristics of cerebrospinal fluid, treatment and prognosis in patients with acquired immune deficiency syndrome (AIDS)-related progressive multifocal leukoencephalopathy (PML) diagnosed by second generation sequencing techniques with cerebrospinal fluid.Methods:From October, 2017 to January, 2019, ten patients with AIDS-related PML were diagnosed by second generation sequencing techniques with cerebrospinal fluid, and their clinical data were retrospectively reviewed. Descriptive analysis was used.Results:Among the ten patients with AIDS-related PML, eight were males and two were females. The age was (38.7±8.2) years. The median CD4 + T lymphocyte count was 46/μL. The median human immunodeficiency virus (HIV) RNA was 5.99×10 4copies/mL. The main clinical manifestations included dyskinesia in four patients, dizziness in three patients, cognitive decline in two patients, and speech disorder in one patient. Three patients developed convulsion throughout the course of the disease. Image findings indicated that lesions could appear in any part, including lesions located under the tentorium of cerebellum in three cases, and above the cerebellum in seven cases. Mild increase of total protein was observed in the cerebrospinal fluid of four cases, while white blood cell count ((0-10)×10 6/L), sugar and chloride were normal in all cases. The reads of JC virus sequence in the cerebrospinal fluid ranged from 3-12 531 reads (median 67 reads). All the patients received antiviral therapy containing integrase inhibitors. Among the 10 patients, two died in hospital and eight survived, and two of them had survived for more than one year. The symptoms were improved in five patients and unchanged in three patients. Conclusions:PML is less common in patients with HIV/AIDS. The second generation sequencing techniques with cerebrospinal fluid can help to diagnose the disease together with clinical manifestations, routine detection of cerebrospinal fluid and imaging. Potent antiretroviral treatment may improve the prognosis of the patients.

ABSTRACT

Objective:To analyze the pathological patterns, clinical features, and prognosis in patients with human immunodeficiency virus (HIV) infection complicated with kidney disease.Methods:A retrospective analysis of 21 renal damage cases in HIV-infected patients undergoing renal biopsy from June 2016 to November 2019 in Shanghai Public Health Clinical Center, Fudan University was conducted. The clinical features, renal pathological patterns, therapies and outcomes were summarized and analyzed.Results:The age of 21 patients was (45.4±11.0) years. There were 19 men and two women. The CD4 + T lymphocyte count was (473.7±218.4) cells/μL. The HIV RNA levels were measured in 20 patients, and 13 cases (65.0%) were less than 40 copies/mL. A total of 18 cases (85.7%) had initiated antiretroviral therapy before renal biopsy, and the treatment time was 12 (1, 47) months. As for the clinical diagnosis, 14 cases (66.7%) were nephrotic syndrome and seven cases (33.3%) were nephritic syndrome. Renal pathology reports showed that HIV immune-complex kidney disease was the most common pathology pattern, accounting for 42.9% (9/21), followed by podocytopathy and diabetic nephropathy, both accounting for 23.8% (5/21), respectively. The IgA nephropathy (23.8%, 5/21) was the most common subtype of HIV immune-complex kidney disease, while minimal change disease (19.0%, 4/21) was the most common one of podocytopathy. However, classic HIV-associated nephropathy was not found in the study. The follow-up period was (12.5±9.2) months. During this period, the nephropathy conditions of nine patients were improved, eight were stable, two deteriorated, and two died. Conclusions:IgA nephropathy, minimal change disease and diabetic nephropathy are the top three patterns of renal pathology in patients with HIV infection. Most cases have good prognosis after treatments. For HIV-infected patients with serious renal damage, timely kidney biopsy is vital to determine pathological pattern, and to subsequently guide the clinical treatment and evaluate the prognosis.

ABSTRACT

BACKGROUND@#Numerous studies have focused on lymphoma among patients infected with human immunodeficiency virus (HIV). However, little is known about the treatment options and survival rate of lymphoma in the Chinese people living with HIV (PLHIV). Our study aimed to investigate the prognosis and compare outcome of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab(R-CHOP) as front line therapy for PLHIV with diffuse large B-cell lymphoma (DLBCL) receiving modern combined antiretroviral therapy (cART).@*METHODS@#A retrospective analysis evaluating PLHIV with DLBCL was performed in Shanghai Public Health Clinical Center from July 2012 to September 2019. The demographic and clinical data were collected, and overall survival (OS) and progression-free survival (PFS) analyses of patients receiving R-CHOP or DA-EPOCH-R therapy were performed by Kaplan-Meier analysis. Additionally, a Cox multiple regression model was constructed to identify related factors for OS.@*RESULTS@#A total of 54 eligible patients were included in the final analysis with a median follow-up of 14 months (interquartile range [IQR]: 8-29 months). The proportion of high international prognostic index (IPI) patients was much larger in the DA-EPOCH-R group (n = 29) than that in the R-CHOP group (n = 25). The CD4 cell counts and HIV RNA levels were not significantly different between the two groups. The 2-year OS for all patients was 73%. However, OS was not significantly different between the two groups, with a 2-year OS rate of 78% for the DA-EPOCH-R group and 66% for the R-CHOP group. Only an IPI greater than 3 was associated with a decrease in OS, with a hazard ratio of 5.0. The occurrence of grade 3 and 4 adverse events of chemotherapy was not significantly different between the two groups.@*CONCLUSIONS@#Outcomes of R-CHOP therapy do not differ from those of DA-EPOCH-R therapy. No HIV-related factors were found to be associated with the OS of PLHIV in the modern cART era.
