Objective: To investigate the expression of glycoprotein non metastatic melanoma protein B (GPNMB) in renal eosinophilic tumors and to compare the value of GPNMB with CK20, CK7 and CD117 in the differential diagnosis of renal eosinophilic tumors. Methods: Traditional renal tumor eosinophil subtypes, including 22 cases of renal clear cell carcinoma eosinophil subtype (e-ccRCC), 19 cases of renal papillary cell carcinoma eosinophil subtype (e-papRCC), 17 cases of renal chromophobe cell carcinoma eosinophil subtype (e-chRCC), 12 cases of renal oncocytoma (RO) and emerging renal tumor types with eosinophil characteristics [3 cases of eosinophilic solid cystic renal cell carcinoma (ESC RCC), 3 cases of renal low-grade eosinophil tumor (LOT), 4 cases of fumarate hydratase-deficient renal cell carcinoma (FH-dRCC) and 5 cases of renal epithelioid angiomyolipoma (E-AML)], were collected at the Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2017 to March 2022. The expression of GPNMB, CK20, CK7 and CD117 was detected by immunohistochemistry and statistically analyzed. Results: GPNMB was expressed in all emerging renal tumor types with eosinophil characteristics (ESC RCC, LOT, FH-dRCC) and E-AML, while the expression rates in traditional renal eosinophil subtypes e-papRCC, e-chRCC, e-ccRCC and RO were very low or zero (1/19, 1/17, 0/22 and 0/12, respectively); the expression rate of CK7 in LOT (3/3), e-chRCC (15/17), e-ccRCC (4/22), e-papRCC (2/19), ESC RCC (0/3), RO (4/12), E-AML(1/5), and FH-dRCC (2/4) variedly; the expression of CK20 was different in ESC RCC (3/3), LOT(3/3), e-chRCC(1/17), RO(9/12), e-papRCC(4/19), FH-dRCC(1/4), e-ccRCC(0/22) and E-AML(0/5), and so did that of CD117 in e-ccRCC(2/22), e-papRCC(1/19), e-chRCC(16/17), RO(10/12), ESC RCC(0/3), LOT(1/3), E-AML(2/5) and FH-dRCC(1/4). GPNMB had 100% sensitivity and 97.1% specificity in distinguishing E-AML and emerging renal tumor types (such as ESC RCC, LOT, FH-dRCC) from traditional renal tumor types (such as e-ccRCC, e-papRCC, e-chRCC, RO),respectively. Compared with CK7, CK20 and CD117 antibodies, GPNMB was more effective in the differential diagnosis (P<0.05). Conclusion: As a new renal tumor marker, GPNMB can effectively distinguish E-AML and emerging renal tumor types with eosinophil characteristics such as ESC RCC, LOT, FH-dRCC from traditional renal tumor eosinophil subtypes such as e-ccRCC, e-papRCC, e-chRCC and RO, which is helpful for the differential diagnosis of renal eosinophilic tumors.

Concordance between three integrated scores based on prostate biopsy and grade-grouping of radical prostatectomy specimen / 中华病理学杂志

Objective: To analyze three different integrated scoring schemes of prostate biopsy and to compare their concordance with the scoring of radical prostatectomy specimens. Methods: A retrospective analysis of 556 patients with radical prostatectomy performed in Nanjing Drum Tower Hospital, Nanjing, China from 2017 to 2020. In these cases, whole organ sections were performed, the pathological data based on biopsy and radical prostatectomy specimens were summarized, and 3 integrated scores of prostate biopsy were calculated, namely the global score, the highest score and score of the largest volume. Results: Among the 556 patients, 104 cases (18.7%) were classified as WHO/ISUP grade group 1, 227 cases (40.8%) as grade group 2 (3+4=7); 143 cases (25.7%) as grade group 3 (4+3=7); 44 cases (7.9%) as grade group 4 (4+4=8) and 38 cases (6.8%) as grade group 5. Among the three comprehensive scoring methods for prostate cancer biopsy, the consistency of global score was the highest (62.4%). In the correlation analysis, the correlation between the scores of radical specimens and the global scores was highest (R=0.730, P<0.01), while the correlations of the scores based on radical specimens with highest scores and scores of the largest volume based on biopsy were insignificant (R=0.719, P<0.01; R=0.631, P<0.01, respectively). Univariate and multivariate analyses showed tPSA group and the three integrated scores of prostate biopsy were statistically correlated with extraglandular invasion, lymph node metastasis, perineural invasion and biochemical recurrence. Elevated global score was an independent prognostic risk factor for extraglandular invasion and biochemical recurrence in patients; increased serum tPSA was an independent prognostic risk factor for extraglandular invasion; increased hjighest score was an independent risk factor for perineural invasion. Conclusions: In this study, among the three different integrated scores, the overall score is most likely corresponded to the radical specimen grade group, but there is difference in various subgroup analyses. Integrated score of prostate biopsy can reflect grade group of radical prostatectomy specimens, thereby providing more clinical information for assisting in optimal patient management and consultation.

Therapy of Dispelling Stasis， Removing Toxin， and Promoting Urination （Xuebijing Injection Combined with Modified Linggui Zhugantang） Affects Prognosis of Sepsis-induced Cardiomyopathy / 中国实验方剂学杂志

ObjectiveTo evaluate the effect of the therapy of dispelling stasis， removing toxin， and promoting urination （modified Linggui Zhugantang combined with Xuebijing injection） on the prognosis of sepsis-induced cardiomyopathy （SICM）. MethodA total of 96 patients were randomly assigned into an observation group and a control group， with 48 patients in each group. The patients in the control group received sepsis bundle， and those in the observation group additionally received the therapy of dispelling stasis， removing toxin， and promoting urination （intravenous drip of Xuebijing injection and oral administration of modified Linggui Zhugantang）. The course of treatment in both groups was 7 days. The disease and prognosis indicators ［28-day mortality， intensive care unit （ICU） length of stay， major adverse cardiac events （MACE）， acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ）， sequential organ failure assessment （SOFA） score， and mortality in emergency department sepsis （MEDS） score］， cardiac function indicators ［left ventricular ejection fraction （LVEF）， E/A ratio of peak velocity blood flow from left ventricular relaxation in early diastole （the E wave） to peak velocity flow in late diastole caused by atrial contraction （the A wave）， E/e′ ratio of mitral peak velocity of early filling （E） to early diastolic mitral annular velocity （e′）， and afterload-corrected cardiac performance （ACP）］， myocardial injury markers ［high-sensitivity cardiac troponin T （hs-cTnT）， N-terminal pro-brain natriuretic peptide （NT-proBNP）， heart-type fatty acid-binding protein （H-FABP）， and high mobility group box-1 （HMGB-1）］， hemodynamic indicators ［extravascular lung water index （EVLWI）， global end-diastolic volume index （GEDVI）， cardiac index （CI）， and systemic vascular resistance index （SVRI）］， and TCM syndrome scores were assessed and compared between the two groups. ResultThe 28-day mortality and the incidence of MACE in the observation group were slightly lower than those in the control group. The ICU length of stay in the observation group was shorter than that in the control group （P<0.05）. After treatment， APACHE Ⅱ， SOFA， MEDS， syndrome score of stasis-caused internal obstruction， E/e′ ratio， hs-cTnT， NT-proBNP， H-FABP， and HMGB1 decreased compared with those before treatment （P<0.05）， while LVEF， E/A ratio， and ACP increased （P<0.05）. Moreover， the changes were more significant in the observation group （P<0.05）. On days 3， 5， and 7 after treatment， the EVLWI and SVRI in the observation group were lower than those in the control group （P<0.05）， while CI showed an opposite trend （P<0.05）. The observation group had higher GEDVI than the control group on days 3 and 5 after treatment （P<0.05）. ConclusionOn the basis of conventional bundle therapy， modified Linggui Zhugantang combined with Xuebijing injection with the effect of dispelling stasis， removing toxin， and promoting urination can inhibit the generation of myocardial injury markers and improve hemodynamics to shorten the length of ICU stay， mitigate the TCM syndrome， and reduce the risk of death， thereby improving the prognosis of SICM.

Epidemiological trends of schistosomiasis in Poyang County of Jiangxi Province from 2004 to 2020 based on the Joinpoint regression model / 中国血吸虫病防治杂志

Objective To analyze the dynamic changes of schistosomiasis in Poyang County of Jiangxi Province from 2004 to 2020, so as to provide insight into the development of the schistosomiasis elimination strategy. Methods Schistosomiasis control data were captured from Poyang County from 2004 to 2020, and the epidemiological data of schistosomiasis were collected from national schistosomiasis surveillance sites in Poyang County from 2005 to 2020. The endemic status of schistosomiasis was analyzed in Poyang County from 2004 to 2020, and a Joinpoint regression analysis was performed to investigate the trends of schistosomiasis in Poyang County from 2004 to 2020. Results The sero-prevalence and egg-prevalence of human Schistosoma japonicum infections reduced from 24.39% (24 976/102 397) and 4.53% (259/5 721) in 2004 to 5.37% (2 421/45 100) [annual percent change (APC) = average annual percent change (AAPC) = −8.64%] and 0 (0/3 963) in 2020 (APC = AAPC = −32.07%) in Poyang County, and the trends were both significant (both P < 0.01). The sero-prevalence of S. japonicum infections reduced from 1.21% (294/24 332) in bovines in 2013 to 0.58% (35/5 999) in 2020 in Poyang County, with one turning point (AAPC = −8.20%, P > 0.05). There were no townships or villages with emerging snail habitats in Poyang County from 2004 to 2020, and there were three turning points of trend in the proportion of snail areas detected in total snail areas (AAPC = −2.30%, P > 0.01). The sero-prevalence and adjusted prevalence of S. japonicum infections reduced from 60.82% (742/1 220) and 10.16% (124/1 220) in local residents in 2005 to 5.73% (70/1 221) and 0 in 2020 in national schistosomiasis surveillance sites of Poyang County, and the trends for sero-prevalence (APC = AAPC = 17.47%, P < 0.01) and adjusted prevalence of S. japonicum infections (APC = AAPC = −44.92%, P < 0.01) were both statistically significant. S. japonicum infections were identified in 10 (2005) and 2 local livestock (2007), with prevalence of 10.00% (10/100) and 13.33% (2/15), respectively, and S. japonicum infections were detected in snails in 2008 and 2009; however, no positive samples of mixed O. hupensis were detected by loop-mediated isothermal amplification. Conclusions The endemic situation of schistosomiasis control had remarkably reduced in Poyang County from 2004 to 2020; however, there are still challenges for consolidating schistosomiasis control achievements and even elimination of schistosomiasis.

Correlation analysis between SUV index in 18F-FDG PET/CT imaging and invasiveness of early lung adenocarcinoma / 中华核医学与分子影像杂志

Objective:To investigate the correlation between the SUV index (SUV max of the lesion/SUV mean of the liver) in 18F-FDG PET/CT imaging and the invasiveness of early lung adenocarcinoma presenting as ground-glass nodule (GGN). Methods:From January 2012 to March 2020, 167 GGN patients (49 males, 118 females; age: (61.5±9.0) years) with early lung adenocarcinoma who underwent PET/CT imaging in Changzhou First People′s Hospital were retrospectively enrolled. The image parameters including the GGN number, location, type, edge, shape, abnormal bronchus sign, vacuole sign, pleural depression, vessel convergence sign, GGN diameter ( DGGN), solid component diameter ( Dsolid), consolidation to tumor ratio (CTR, Dsolid/ DGGN), CT values (CT value of ground-glass opacity (CT GGO), CT value of lung parenchyma (CT LP), ΔCT GGO-LP (CT GGO-CT LP)) and SUV index were analyzed. Single and multivariate logistic regressions were used to analyze the correlation between SUV index and infiltration. The generalized additive model was used for curve fitting, and the piece-wise regression model was used to further explain the nonlinearity. Results:In 189 GGNs, invasive adenocarcinoma accounted for 85.2% (161/189). Single logistic regression showed that the GGN number, type, shape, edge, abnormal bronchus sign, pleural depression, vessel convergence sign, DGGN, Dsolid, CTR, CT GGO, ΔCT GGO-LP and SUV index were related factors of infiltration (odds ratio ( OR) values: 0.396-224.083, P<0.001 or P<0.05). After fully adjusting for confounding factors, SUV index was significantly correlated with increased risk of invasion ( OR=2.162 (95% CI: 1.191-3.923), P=0.011). Curve fitting showed that the SUV index was non-linearly related to the risk of infiltration, and the risk of infiltration increased significantly only when the SUV index was greater than 0.43 ( OR=3.509 (95% CI: 1.429-8.620), P=0.006). The correlation between SUV index and infiltration had no interaction between age, vacuoles, pleural depression and CTR subgroups (all P>0.05). Conclusions:SUV index is an independent factor related to the invasiveness of early lung adenocarcinoma. The higher the SUV index, the greater the risk of invasion; but the two are not simply linearly correlated.

Assessment of left ventricular diastolic dyssynchrony and its influencing factors early after acute myocardial infarction by SPECT gated myocardial perfusion imaging: an experimental study / 中华核医学与分子影像杂志

Objective:To evaluate the left ventricular diastolic dyssynchrony (LVDD) and its influencing factors early after acute myocardial infarction (AMI) using phase analysis of SPECT gated myocardial perfusion imaging (GMPI).Methods:Bama miniature swines ( n=16) were subjected to establish AMI models. GMPI was performed before and 1 d after AMI to obtain the extent of myocardial perfusion defect (Extent, %) and left ventricular systolic dyssynchrony (LVSD)/LVDD parameters, namely the phase histogram bandwidth (PBW) and phase standard deviation (PSD). Meanwhile, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), and the ratio of early to late peak mitral diastolic flow (E/A) were obtained by echocardiography. Independent-sample t test, paired t test and Pearson correlation analysis were used to analyze the data. Results:Sixteen AMI swines were successfully created. Compared to baseline, Extent, LVEDV and LVESV significantly increased on 1 d after AMI ( t values: -11.14, -4.55, -6.12, all P<0.001), while LVEF and E/A significantly decreased ( t values: 10.16, 2.18, P<0.001, P=0.046). GMPI showed that the LVDD parameters PBW and PSD increased significantly on 1 d after AMI when compared to those at baseline((142.25±72.06)° vs (33.06±8.98)°, (56.15±26.71)° vs (12.51±5.13)°; t values: -6.11, -6.60, both P<0.001). There were significant differences between LVSD parameters and LVDD parameters (PBW: (109.06±62.40)° vs (142.25±72.06)°, PSD: (44.40±25.61)° vs (56.15±26.71)°; t values: -2.73, -2.20, P values: 0.016, 0.044). LVDD parameters PBW, PSD were negatively correlated with E/A after AMI ( r values: -0.569, -0.566, P values: 0.021, 0.022), and positively correlated with the Extent ( r values: 0.717, 0.634, P values: 0.002, 0.008). The phase analysis of SPECT GMPI to evaluate LVDD showed good intra-observer and inter-observe reproducibility (intraclass correlation coefficient (ICC): 0.953-0.984, all P<0.001). Conclusions:LVDD occurs early on 1 d after AMI, and can reflect left ventricular diastolic dysfunction. The Extent is correlated with LVDD significantly. Phase analysis of SPECT GMPI is an accurate method to evaluate LVDD and left ventricular diastolic function.

Construction and validation of the predictive models for the pathological invasion of early lung adenocarcinoma presenting as ground glass nodules based on 18F-FDG PET/CT / 中华核医学与分子影像杂志

Objective:To construct and verify of the predictive models for pathologic invasion of early lung adenocarcinoma with ground glass nodules (GGNs) based on 18F-FDG PET/CT. Methods:A retrospective analysis was conducted on 149 patients (44 males, 105 females; age (61.1±8.9) years) with pre-invasive lesions/minimally invasive adenocarcinoma (MIA) and invasive adenocarcinoma (IAC) confirmed by pathology after surgery in the First People′s Hospital of Changzhou from October 2011 to October 2019. All patients underwent PET/CT for GGNs. GGNs were randomly divided into a modeling group and validation group with the proportion of 1∶1. Mann-Whitney U test or χ2 test was used to compare the qualitative morphological characteristics (shape, edge characteristics, etc.), quantitative parameters (consolidation-to-tumor ratio, attenuation value of the ground glass opacity (GGO) component on CT (CT GGO), etc.) and quantitative functional parameters (SUV max and SUV index(GGNs SUV max/liver SUV mean) of pre-invasive lesions/MIA and IAC. Logistic regression analysis was used to construct the models, and the ROC curve was used to verify the models′ robustness. Different AUCs were compared by Delong test. Results:A total of 170 GGNs were removed by surgery and confirmed pathologically. In the modeling group ( n=89), the proportion of mixed GGNs, irregular shape, edge characteristics, bronchiectasis/twist/truncation sign, GGNs maximum diameter and solid component maximum diameter, consolidation-to-tumor ratio, CT GGO, SUV max and SUV index in IAC group were significantly higher than those in pre-invasive/MIA group ( χ2 values: 5.00-23.40, z values: from -6.53 to -2.70, all P<0.05). Models 1-3 were constructed based on the qualitative parameters (GGNs type, edge characteristics), quantitative parameters (CT GGO, SUV index), combined qualitative and quantitative parameters (GGNs type, edge characteristics, SUV index) of PET/CT, respectively, and the AUCs of ROC were 0.896, 0.880 and 0.931 in the modeling group, respectively. And the AUC of model 2 was not decreased significantly in the validation group ( n=81; AUC=0.802; z=0.81, P=0.417). Conclusion:The model combined with morphological and functional quantitative parameters of 18F-FDG PET/CT can effectively predict the pathological invasion of early lung adenocarcinoma, and the constructed model is robust.

Epidemiological and clinical features of children with mild coronavirus disease 2019 / 中国当代儿科杂志

OBJECTIVE@#To study the epidemiological and clinical features of children with mild coronavirus disease 2019 (COVID-19).@*METHODS@#The children who were diagnosed with mild COVID-19 in the Wuchang Shelter Hospital in Wuhan from February 5 to March 10, 2020 were enrolled as subjects. The clinical, laboratory, and lung imaging data were collected during hospitalization and isolation. This was a retrospective single-center case series analysis.@*RESULTS@#A total of 1 124 patients with mild COVID-19 were admitted from February 5 to March 10, 2020, including 13 children (1.16%). All the 13 children (7 boys and 6 girls) were residents of Wuhan in China, with a median age of 16 years (range: 10-18 years). Of all the 13 children, 9(69%) were from family clusters of COVID-19 and 4(31%) had unknown sources of infection. The mean time from exposure to onset was 6.8 days (range: 2-13 days) in 9 children with a definite history of exposure. There were 6 symptomatic children with the main manifestations of fever, cough, weakness, and myalgia, and the mean time from onset to hospitalization was 9.2 days. Of all the 13 children, 7(54%) were asymptomatic with positive nucleic acid test of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). There were 4 children (31%) with abnormal lung CT findings, mainly patchy shadows or ground-glass opacities in the lung field, and 6 children (46%) had no symptoms with normal lung CT findings. All children had normal routine blood test results and C-reactive protein levels. Eight children underwent SARS-CoV-2 IgM and IgG tests at least once, among whom 6 had negative SARS-CoV-2 IgM but positive IgG, and 2 underwent SARS-CoV-2 IgM and IgG tests twice and had negative results. Of all the 13 children, 11(85%) had negative results of two SARS-CoV-2 nucleic acid tests during hospitalization and were discharged, and 2(15%) had positive results of four SARS-CoV-2 nucleic acid tests and were transferred to another hospital and lost to follow-up. Among the 11 children who were followed up, 1 had positive results of two SARS-CoV-2 nucleic acid tests at the isolation point, and 10 had negative results. The mean hospital stay was 10.9 days for the 13 children. Eleven children recovered during follow-up, with good living and learning conditions.@*CONCLUSIONS@#Children with mild COVID-19 often have an uncertain history of exposure and may not have any clinical symptoms. Etiological diagnosis is more important than clinical diagnosis. The disappearance of clinical manifestations may not parallel with the result of SARS-CoV-2 nucleic acid test. SARS-CoV-2 has a long detoxification time, and there may be recurrent cases of SARS-CoV-2 positivity. Further studies are needed to investigate the production patterns of SARS-CoV-2 IgM and IgG and their effect on the body.

Research advances in the treatment strategies for severe pertussis in children / 中国当代儿科杂志

At present, effective antibiotics and comprehensive symptomatic/supportive treatment as early as possible are mainly used for the treatment of severe pertussis in clinical practice. However, some children with severe pertussis have unsatisfactory response to commonly used drugs and treatment measures in the intensive care unit and thus have a high risk of death. Studies have shown that certain treatment measures given in the early stage, such as exchange transfusion, may help reduce deaths, but there is still a lack of uniform implementation norms. How to determine the treatment regimen for severe pertussis and improve treatment ability remains a difficult issue in clinical practice. This article reviews the advances in the treatment of severe pertussis, in order to provide a reference for clinical treatment and research.

To investigate the application of Acute Gastrointestinal Injury(AGI) grading in evaluating gastrointestinal failure in patients with acute pancreatitis(AP). In this retrospective observational study,patients presented with moderate severe AP and severe AP in our hospital from October 2013 to October 2016 were consecutively enrolled.Logistic regression analysis and receiver operating characteristic curve were used to explore and evaluate potential predictors of gastrointestinal failure. A total of 202 patients were included in this study,with 90 cases(44.6%) identified as gastrointestinal failure.Survival curve showed significantly increased risk of death in patients with gastrointestinal failure( < 0.05).Logistic regression analysis showed age(=1.06,95%:1.03-1.09,<0.001),complaint of stopping flatus and defecation(=7.02,95%:2.08-23.66,=0.002),increased counts of white blood cells in peripheral blood(=1.09,95%:1.02-1.17,=0.015),decreased level of serum albumin(=0.93,95%:0.86-1.00,=0.048),and increased level of serum creatinine at admission(=1.02,95%:1.01-1.04,=0.001) were the independent risk factors of gastrointestinal failure.The area under curves of Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) and Beside Index for Severity in Acute Pancreatitis (BISAP) scores in diagnosing gastrointestinal failure were 0.999 and 0.782,respectively. Gastrointestinal failure can remarkably increase the risk of death in patients with AP.Both APACHE Ⅱ and BISAP scores at admission are useful in diagnosing gastrointestinal failure in patients with AP.

Roles of the public-facility-turned temporary hospital in prevention and control of coronavirus disease 2019 in Wuhan, China and clinical experience in the hospital / 中国当代儿科杂志

Since the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China, the public-facility-turned temporary hospital (PFTH) has played an important role in preventing the spread of the epidemic. Wuchang PFTH is the first one to put into clinical practice and the last one suspended in Wuhan. The National Emergency Medical Rescue Team of the Second Xiangya Hospital of Central South University, together with other 13 medical teams (841 medical staff in total), have fulfilled the task for the treatment of non-severe COVID-19 patients, without any medical staff infected. The first author of the article was the only pediatrician working in the Wuchang PFTH. The author describes and summarizes the features/functions, management/operations, and advantages/challenges of the PFTH, in order to provide reference for medical institutions and relevant departments to deal with public health emergencies.

Evolution of blood lipids and risk factors of dyslipidemia among people living with human immunodeficiency virus who had received first-line antiretroviral regimens for 3 years in Shenzhen / 中华医学杂志(英文版)

BACKGROUND@#Lipid abnormalities are prevalent among people living with human immunodeficiency virus (HIV) (PLWH) and contribute to increasing risk of cardiovascular events. This study aims to investigate the incidence of dyslipidemia and its risk factors in PLWH after receiving different first-line free antiretroviral regimens.@*METHODS@#PLWH who sought care at the Third People's Hospital of Shenzhen from January 2014 to December 2018 were included, and the baseline characteristics and clinical data during the follow-up were collected, including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). The risk factors of dyslipidemia after antiretroviral therapy were analyzed with the generalized estimating equation model.@*RESULTS@#Among the 7623 PLWH included, the mean levels of TC, HDL-C and LDL-C were 4.23 ± 0.85 mmol/L, 1.27 ± 0.29 mmol/L and 2.54 ± 0.65 mmol/L, respectively, and the median TG was 1.17 (IQR: 0.85-1.68) mmol/L. Compared with that in PLWH receiving tenofovir disoproxil fumarate (TDF) + lamivudine (3TC) + ritonavir-boosted lopinavir (LPV/r), zidovudine (AZT) + 3TC + efavirenz (EFV), and AZT + 3TC + LPV/r, the incidence of dyslipidemia was lower in PLWH receiving TDF + 3TC + EFV. In multivariate analysis, we found that the risks of elevations of TG, TC, and LDL-C were higher with TDF + 3TC + LPV/r (TG: odds ratio [OR] = 2.82, 95% confidence interval [CI]: 2.55-3.11, P < 0.001; TC: OR = 1.24, 95% CI: 1.14-1.35, P < 0.001; LDL: OR = 1.06, 95% CI: 1.00-1.12, P = 0.041), AZT + 3TC + EFV (TG: OR = 1.41, 95% CI: 1.28-1.55, P < 0.001; TC: OR = 1.43, 95% CI: 1.31-1.56, P < 0.001; LDL: OR = 1.18, 95% CI: 1.12-1.25, P < 0.001), and AZT + 3TC + LPV/r (TG: OR = 3.08, 95% CI: 2.65-3.59, P < 0.001; TC: OR = 2.40, 95% CI: 1.96-2.94, P < 0.001; LDL: OR = 1.52, 95% CI: 1.37-1.69, P < 0.001) than with TDF + 3TC + EFV, while treatment with TDF + 3TC + LPV/r was less likely to restore HDL-C levels compared with TDF + 3TC + EFV (OR = 0.95, 95% CI: 0.92-0.97, P < 0.001). In addition to antiretroviral regimens, antiretroviral therapy duration, older age, overweight, obesity and other traditional factors were also important risk factors for dyslipidemia.@*CONCLUSION@#The incidence of dyslipidemia varies with different antiretroviral regimens, with TDF + 3TC + EFV having lower risk for dyslipidemia than the other first-line free antiretroviral regimens in China.

Effect of feedback pulmonary rehabilitation guidance on self-management of elderly patients with stable chronic obstructive pulmonary disease / 中华健康管理学杂志

Objective:To observe the effect of feedback pulmonary rehabilitation guidance on self-management of elderly patients with stable chronic obstructive pulmonary disease (COPD).Methods:Ninety-four elderly patients with stable COPD that visited the outpatient department between January 2018 and January 2019 were selected. Block randomization methods were used to divide the patients into two groups: routine lung rehabilitation instruction group (referred to as the “routine group”) and feedback lung rehabilitation group (referred to as the “feedback group”). The feedback group received the instruction of feedback pulmonary rehabilitation guidance, while the routine group received the instruction of routine pulmonary rehabilitation guidance. The quality of life and the self-management ability of the two groups before and after the intervention were compared.Results:There was no statistically significant difference between the scores of the feedback and routine groups before the intervention of the COPD-specific self-management scale ( P>0.05). In the feedback group, the scores of emotional management, daily life management, symptom management, self-efficacy management, and information management on the COPD-specific self-management scale after the intervention were 45.01±5.31, 53.10±6.60, 25.88±3.03, 35.01±5.31, and 24.32±4.20, respectively, whereas those for the routine group were 40.23±5.19, 48.02±6.58, 22.88±3.01, 31.01±4.80, and 20.30±2.88, respectively. The scores of the feedback group were higher than the routine group and the difference was significant ( P<0.001). There was no significant difference between the feedback group and the routine group before the intervention of the respiratory disease questionnaire, i.e., the airways questionnaire 20-revised (AQ20-R) score ( P>0.05). The AQ20-R score of the feedback group after the intervention was 7.22±1.08, which was lower than that of the routine group (9.01±2.01); the difference was significant ( P<0.001). Conclusion:The application of feedback pulmonary rehabilitation guidance in the self-management of elderly patients with stable COPD can improve both their self-management ability and quality of life.
