ABSTRACT
Objective:Rat model of RA complicated with pulmonary fibrosis were constructed to observe the degree of improvement of pulmonary fibrosis in RA rats by JAK2 inhibitor CEP33779 and the possible mechanisms.Methods:①The RA models were constructed by subcutaneous injection of 0.2 ml (1 mg/ml) of bovine type Ⅱ collagen into the tail of the rats on the day of modeling development (d0); intratracheal injection of 100 μl bleomycin (2.5 mg/kg) was used to induce pulmonary fibrosis model at d13. In vivo study: model rats were randomly divided into the normal group, pulmonary fibrosis group, pulmonary fibrosis CEP treatment group, RA complicated with pulmonary fibrosis group, and RA complicated pulmonary fibrosis CEP treatment group. Rats in the treatment group was given CEP (10 ml/kg) qd by gavage from d14 to week 4. The right hind foot of the rats was measured for joints swelling and the arthritis index score were measured, lung compliance (Cst) and lung specific gravity were measured. In addition, the pathological changes of the left lung were observed by HE and Masson staining, and the extracellular matrix level of the right lung was measured by protein immunoblotting (WB). ② In vitro study: TGF-β 1 (10 ng/ml) was applied to stimulate human embryonic lung fibroblasts (HFL1) for 24 h and 48h, and p-JAK2 expression was detected by immunofluorescence. After HFL1 inoculation of culture plates, the control group, TGF-β 1 stimulation group, TGF-β 1+ LY2109761 (TGFβ-R1/2 inhibitor group, 0.5 mmol/L and 2 mmol/L) group, TGF-β 1+CEP (0.1 mmol/L and 1.0 mmol/L) group were co-incubated for 48 h, and the expression levels of TGFβ-R2, α-SMA, JAK2, and Col 1 were measured by WB. Comparisons between multiple groups were made by Tukey′s test, and comparisons between the two groups were analyzed by independent t-test. Results:① In vivo study, compared with the control group (1.45±0.04), joint swelling was increased at d13 [(2.54±0.16) in RA+PF+Vehicle group, t=16.02, P<0.001], and the mean arthritis index score and toe volume were decreased 3 days after CEP treatment(d16) [(2.89±0.11), t=5.78, P<0.001; (1.92±0.13), t=6.85, P<0.001]. For rats with pulmonary fibrosis, all had different degrees of lung enlargement, increased lung specific gravity, decreased Cst, and increased lung inflammation and fibrosis[(0.96±0.06), t=19.76, P<0.001; (0.26±0.09), t=17.64, P<0.001; (3.63±1.51), t=6.00, P<0.001; (1.75±0.71), t=5.84, P<0.001]. After CEP gavage, rats that had RA complicated with pulmonary fibrosis had reduced lung swelling, decreased lung specific gravity, increased Cst [(0.82±0.05), t=5.76, P<0.001; (0.43±0.18), t=2.31, P=0.038], and the scores of pulmonary fibrosis and inflammation [(3.00±1.00); (1.56±0.52)] all showed a trend of decrease, but did not reach statistical difference CEP inhibited the expression of TGF-β 1, TGFβ-R2, α-SMA, Fn and JAK2 in lung tissue of pulmonary fibrosis rats, and the differences among the five groups were statistically significant ( F=9.02, P=0.017; F=4.86, P=0.048; F=6.57, P=0.032; F=11.26, P=0.010; F=13.32, P=0.007). ② In vitro study, TGF-β 1 stimulated HFL1 showed stronger phosphorylated JAK2 (p-JAK2) fluorescent signal WB showed a significant increase in the expression of TGFβ-R2, α-SMA, JAK2 and Col1, and after LY and CEP intervention, the above proteins were reduced in a concentration-dependent manner, with statistically significant differences among all five groups ( F=337.30, P<0.001; F=20.61, P<0.001; F=100.60, P<0.001; F=180.90, P<0.001). Conclusion:JAK2 inhibitors can ameliorate RA-related pulmonary fibrosis, and the mechanism may be through interfering with the "crosstalk" between JAK2 and TGF-β 1 signaling pathway.
ABSTRACT
Objective:To investigate the reference range of the length and thickness of the fetal vomer-palate diameters at 11-13 + 6 weeks, and their role in the diagnosis of cleft lip and palate(CLP). Methods:From May 2020 to August 2021, 1 559 pregnant women who underwent ultrasound examination at 11-13 + 6 weeks in Guangdong Women and Children Hospital were selected, and the fetal vomer-palate in the median sagittal plane of the face was observed. The length and thickness diameters of the fetal were measured separately to establish the reference value range of normal fetal.The reference range was compared with the vomer-palate data of fetuses with confirmed CLP. Results:The 1 518 normal fetuses were divided into 11-13 + 6 weeks, 12-12 + 6 weeks and 13-13 + 6 weeks. The reference values of the long diameter of fetal vomer-palatine were 4.3-5.9 mm, 5.0-6.8 mm, 5.4-7.7 mm, and the reference values of the thick diameter were 2.0-2.9 mm, 2.2-3.4 mm, and 2.5-3.8 mm, respectively. The length and thickness of the fetal vomer-palatine were significantly positively correlated with the Crown-rump length ( rs=0.733, 0.634; all P<0.001). In the 1 559 fetals, 25 cases were diagnosed and confirmed with CLP, and the vomer-palate thickness diameters were smaller than the reference values in all cases, meanwhile, the vomer-palate length diameters of 22(88.0)% cases were smaller than the reference values. Conclusions:The reference range of fetal vomer-palate length and thickness at 11-13 + 6 weeks of gestation is valuable for the screening of fetal CLP.
ABSTRACT
Objective:To evaluate the efficacy of a calf tissue flap combined with antibiotic-loaded calcium sulfate (artificial bone or mixed iliac bone graft) in the treatment of foot and ankle osteomyelitis.Methods:A retrospective study was conducted to analyze the 11 cases of foot and ankle osteomyelitis which had been treated at Department of Hand and Microsurgery, The Third Hospital of Baoji from October 2018 to October 2021. There were 8 males and 3 females, aged (42.3±23.7) years. The chronic hypotoxic osteomyelitis was repaired and reconstructed after thorough debridement at one stage with a calf tissue flap combined with antibiotic-loaded calcium sulfate artificial bone to fill the cavity and cover the wound. The acute infected trauma was repaired and reconstructed after thorough debridement at the second stage with a calf tissue flap combined with antibiotic-loaded calcium sulfate artificial bone to fill the cavity and cover the wound only after the acute infection was controlled by local dressing, drainage or negative pressure therapy and systemic anti-infection treatment at the primary stage. The flap size ranged from 3.5 cm × 2.0 cm to 12.0 cm × 6.0 cm. Four cases were treated by a peroneal artery perforator flap combined with antibiotic-loaded calcium sulfate artificial bone, 3 cases by a flap with peroneal artery perforator and peroneal nerve trophic vessel combined with antibiotic-loaded calcium sulfate artificial bone, 3 cases by a posterior tibial artery perforator flap combined with antibiotic-loaded calcium sulfate artificial bone, and one by a peroneus longus muscle flap combined with antibiotic-loaded calcium sulfate artificial bone. Postoperatively, the flap survival, bone union time, ankle function and complications were observed; the therapeutic efficacy was evaluated by comparing infection control indexes at the final follow-up [clinical manifestations like local redness, swelling, pain, ulceration, and exudation, and white blood cell count (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and calcitoninogen (PCT)].Results:All the flaps survived except for one which developed necrosis at the distal 1/3 of the flap but responded to dressing change. All the patients were followed up for (22.6±11.5) months. The 6-month follow-up revealed that all the flaps were fine in shape and texture. Re-examinations showed that WBC, CRP, ESR and PCT were normal or close to normal, the local skin was free of redness, swelling or ulceration, and protective sensation was restored to varying degrees. X-ray at (12.1±2.3) months showed that lesions disappeared, bony union was achieved, the ankle joint regained basic flexion and extension, and the affected limb also regained weight-bearing and walking functions in all the patients but one whose X-ray at 18 months showed poor bony union but no other symptoms or signs.Conclusion:In the treatment of foot and ankle osteomyelitis, a calf tissue flap combined with antibiotic-loaded calcium sulfate artificial bone can promote bone healing and restore the function of the foot and ankle because it not only fills the cavity and covers the wound but also effectively controls the infection.
ABSTRACT
Crohn′s disease (CD) is a chronic, progressive and destructive inflammatory disease affecting the entire digestive tract. Changes in the intestinal microbiota, particularly a decrease in gut microbiome diversity, are thought to be associated with chronic intestinal inflammation of CD. As for the mechanism of antibiotics in CD treatment, some scholars believe that antibiotics can affect the course of disease by reducing the concentration of intestinal bacteria and changing the composition of intestinal microbiota. Different antibiotics, including ciprofloxacin, metronidazole and rifaximin, have been proved to have certain therapeutic effect on some patients with CD in clinical practice, but there are still limitations in the use of antibiotics.In this review, the relationship between intestinal flora and the incidence of CD and the application of antibiotics in CD were reviewed, providing reference and help for the standardized application of antibiotics in CD.
ABSTRACT
Objective:To understand the effects of paliperidone palmitate (PP) long-acting injection on hospitalization, psychiatric symptoms, individual and social function of community patients with schizophrenia.Methods:From March 2021 to September 2022, 239 patients with schizophrenia in the community of Zhongshan city were treated with PP injection in a 1-month dosage form for 1 year.The hospitalization rate was compared before and after the treatment.The brief psychiatric rating scale (BPRS), modified overt aggression scales(MOAS), clinical global impressions-severity(CGI-S), and personal and social performance scale (PSP) were used to evaluate psychiatric symptoms and personal social function at baseline, at the end of the 8th week, the end of the 6th month and the end of the 12th month after treatment.Repeated measurement analysis of variance was used to compare the results at different times of treatment, and Logistic regression analysis was used to analyze the factors affecting treatment by SPSS 26.0.Results:One year after treatment the number of hospitalization was lower than that before (0(1) times, 0(0) times)( Z=-4.43, P<0.01), and the hospitalization days was lower than before (43(83.3) days, 0(0) days)( Z=-8.65, P<0.01) for the schizophrenic patients.The total BPRS score for schizophrenic patients decreased from (45.3±9.2) to (27.5±9.0) after 1 year of treatment( χ2=465.20, P<0.01), and the external aggressive behavior score was lower than the baseline score (1(7), 0(0))( F=308.36, P<0.01). The total effective rates were 30.5%(73/239), 77.4%(185/239) and 81.6%(195/239) after 8 weeks, 6 months and 1 year of treatment, respectively.The impairment in the four aspects of personal and social functioning were improved to varying degrees (all P<0.01). The severity of the disease was reduced 1 year after treatment.And the proportions of partial to very severe, moderate, none or mild were 10.0%(24/239), 56.5%(135/239), and 33.5%(80/239). Ordinal logistic regression analysis showed that younger age at treatment ( β=-0.08, OR=0.93, 95% CI=0.87-0.99) and older age at first onset ( β=0.07, OR=1.07, 95% CI=1.01-1.14) were associated with better treatment outcomes. Conclusion:Long-term injection of paliperidone palmitate can effectively improve the mental symptoms and individual social function of community patients with schizophrenia.

ABSTRACT
【Objective】 To analyze the literature on the relationship between gut microbiota and bone metabolism, identify the current research hotspots and difficulties, and provide research ideas and directions for the clinical prevention and treatment of bone metabolism related diseases. 【Methods】 Based on the Citespace literature visualization analysis software, the co-occurrence and cluster analysis of keywords and other information of the included 394 literatures were performed, and the visual map was drawn. 【Results】 Among the included literatures, the keywords such as inflammatory bowel disease, T cells, dendritic cells, short-chain fatty acids, and chronic kidney disease appeared with high frequency. The cluster of intestinal alkaline phosphatase, metabolic osteoarthritis, dendritic cells, and signaling pathway was the current research hotspot. Recent years have witnessed a rapid increase in published articles in this field, with the United States as the leading origin. 【Conclusion】 The mechanism by which gut microbiota interferes with the immune system and regulates bone metabolism to maintain bone homeostasis is still the core of current research.
ABSTRACT
【Objective】 M3 muscarinic acetylcholine receptor(M3 receptor), encoded by CHRM3 gene, is widely distributed in the cardiovascular system and plays an important role in cardiac regulation. The aim of this study was to assess the association of genetic variants in M3 receptor with blood pressure(BP) responses to controlled dietary sodium and potassium interventions. 【Methods】 A total of 333 subjects from 124 families were recruited from the rural areas of northern China. After a three-day baseline observation, they were sequentially on a seven-day low-salt diet, a seven-day high-salt diet, and a seven-day high-salt diet plus potassium supplementation. Thirteen CHRM3 single nucleotide polymorphisms(SNPs) were selected for analysis. 【Results】 SNP rs10802811 of the CHRM3 was significantly associated with diastolic BP(DBP) and mean arterial pressure(MAP) responses to both low-salt and high-salt diets while SNPs rs6429147, rs373288072, rs114677844 and rs663148 showed significant associations with systolic BP(SBP) and MAP responses to high-salt diet. In addition, SNP rs6692904 was significantly associated with SBP, DBP and MAP responses to high-salt diet with potassium supplementation. 【Conclusion】 Genetic variants in M3 receptor are significantly associated with BP responses to sodium and potassium intervention, suggesting that M3 receptor may be mechanistically involved in BP salt and potassium sensitivity.
ABSTRACT
【Objective】 Based on our previously established salt-sensitive hypertension cohort, we aimed to examine the association of genetic variants in uromodulin with blood pressure(BP) responses to dietary interventions of sodium and potassium intake. 【Methods】 In 2004, 514 subjects from 124 families in Mei County, Shaanxi Province, were recruited to establish the salt-sensitive hypertension study cohort. Among them, 333 non-parent subjects were selected and sequentially maintained on a normal-diet for 3 days, low-salt diet for 7 days, then a high-salt diet for 7 days and a high-salt diet with potassium supplementation for another 7 days. Thirteen single nucleotide polymorphisms(SNPs) in the uromodulin gene were genotyped on the MassARRAY platform. 【Results】 BP levels decreased from the baseline to low-salt diet, increased from low-salt to high-salt diet, and decreased again from the high-salt diet to the high-salt plus potassium supplementation intervention. SNPs rs77875418 and rs4997081 of the uromodulin gene were significantly associated with diastolic BP(DBP) and mean arterial pressure(MAP) responses to high-salt diet. In addition, SNPs rs77875418, rs79245268, rs4293393, rs6497476, rs4997081, rs13333226, and rs12917707 were significantly associated with systolic BP(SBP), DBP, and MAP responses to high-salt diet with potassium supplementation. 【Conclusion】 Genetic variants in uromodulin gene are significantly associated with BP responses to sodium and potassium supplementation, suggesting that uromodulin may be mechanistically involved in BP sodium-sensitivity and potassium-sensitivity.
ABSTRACT
【Objective】 4-like protein with down-regulated expression and development in neural precursor cells (NEDD4L) plays an important role in blood pressure (BP) regulation and sodium homeostasis by regulating epithelial sodium channel protein. In this study, we aimed to explore the relationship of NEDD4L gene polymorphisms with BP responses to sodium and potassium intake. 【Methods】 In 2004, 514 subjects from 124 families in Meixian County, Shaanxi Province, were recruited to establish a salt-sensitive hypertension study cohort. All the subjects received a 3-day baseline survey, a 7-day low-salt diet, a 7-day high-salt diet, and finally a 7-day high-salt and potassium supplementation. Their BP was measured and peripheral blood samples were collected at different intervention periods. The 14 gene polymorphisms of NEDD4L gene were genotyped and analyzed by MassARRAY platform. 【Results】 BP decreased on a low-salt diet, and significantly increased on a high-salt diet, and decreased again after potassium supplementation. NEDD4L SNPs rs74408486 were significantly associated with systolic BP, diastolic BP and mean arterial pressure responses to the low-salt diet. SNPs rs292449 and rs2288775 were significantly associated with pulse pressure response to the high-salt diet. In addition, SNPs rs563283 and rs292449 were significantly associated with diastolic BP, mean arterial pressure, and pulse pressure responses to high-salt and potassium supplementation diet. 【Conclusion】 NEDD4L gene polymorphisms were significantly associated with BP responses to sodium and potassium intake, suggesting that NEDD4L gene may be involved in the development of salt sensitivity and potassium sensitivity.
ABSTRACT
【Objective】 Dyslipidemia has shown to be associated with cardiovascular, metabolic and renal diseases. This study aimed to investigate the association between residual cholesterol and the risk of subclinical renal damage (SRD). 【Methods】 A total of 2 342 participants were recruited from the previously established Hanzhong Adolescent Hypertension Study cohort. According to estimated glomerular filtration rate(eGFR) and urinary albumin-to-creatine ratio(uACR), the subjects were divided into SRD group and non-SRD group. The associations of residual cholesterol with eGFR, uACR, and the risk of SRD were analyzed by multiple linear and Logistic regression analyses. 【Results】 Residual cholesterol was positively correlated with uACR(r=0.081, P<0.001) but negatively correlated with eGFR (r=-0.091, P<0.001). Multiple linear regression analysis revealed that residual cholesterol was an influencing factor of uACR (β=0.075, P<0.001) and eGFR (β=-0.027, P<0.001) after adjustment for gender, age, smoke, alcohol, exercise, BMI, hypertension, diabetes and serum uric acid. In addition, Logistic regression analysis revealed that residual cholesterol was significantly associated with the risk of SRD independently of potential confounders [OR(95% CI)=1.387 (1.113-1.728), P<0.001]. Further subgroup analysis showed that residual cholesterol was significantly associated with the risk of SRD in women but not in men. 【Conclusion】 Residual cholesterol is a contributing factor in the risk of subclinical renal damage with gender-specific association.

ABSTRACT
BackgroundIn relation to neurodevelopmental hypothesis in the etiology of schizophrenia， brain-derived neurotrophic factor （BDNF） as a neurotrophin occupies a relatively dominant position in neuronal development and is a potential biomarker for schizophrenia， and previous studies have suggested that its serum concentration and genetic polymorphisms play a vital role in the pathogenesis of schizophrenia， but this remains controversial. ObjectiveTo analyze the difference in BDNF serum concentration between schizophrenic patients and healthy controls， and to explore the correlation of three BDNF single nucleotide polymorphism （SNPs） including rs11030101， rs2030324 and rs6265 with BDNF serum concentration and clinical symptoms in patients with schizophrenia， thus providing references for the clinical treatment of schizophrenia. MethodsA case-control study was conducted on 55 patients with schizophrenia who attended the Zhongshan Third People's Hospital from January 2019 to December 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， and 31 healthy controls concurrently recruited from the hospital or general population. Positive and Negative Symptom Scale （PANSS） was utilized to evaluate the psychiatric symptoms of patients with schizophrenia. BDNF serum concentration in all participants was measured using enzyme-linked immunosorbent assay （ELISA）， and the genotype distributions of three BDNF SNPs （rs11030101， rs2030324， rs6265） were investigated by polymerase chain reaction sequence-based typing method. ResultsBDNF serum concentration in patient group was lower than that in control group， with statistical difference （t=-3.804， P<0.01）. In terms of clinical symptoms， PANSS total score， excitement/hostility domain score， and depression/anxiety domain score demonstrated statistical difference among patients with different genotypes at SNP rs11030101 （t=2.022， Z=-2.696， -2.467， P<0.05 or 0.01）. No statistical difference was noted in BDNF serum concentration in patients with different genotypes at three BDNF SNPs （Z=1.483， F=2.584， 0.417， P>0.05）. ConclusionPatients with schizophrenia are found to have low BDNF serum concentration， and the three BDNF SNPs （rs11030101， rs2030324， rs6265） are not associated with BDNF serum concentration， whereas the BDNF rs11030101 polymorphism may contribute to the manifestation of clinical symptoms of excitement/hostility and depression/anxiety in patients with schizophrenia. Furthermore， BDNF serum concentration seems to be more dependent on clinical diagnosis effect rather than genetic polymorphism. ［Funded by Guangdong Province Medical Science and Technology Research Fund Project （number， A2021205）； Zhongshan Medical Research Program （number， 2022J221）］
ABSTRACT
Diffuse pleural mesothelioma is a malignant mesothelioma, which is characterized by diffuse involvement of pleura or pericardium, strong invasion, high malignancy and poor prognosis. The onset of diffuse pleural mesothelioma is concealed. Most of them are in the late stage at the initial diagnosis. The treatment is difficult and the curative effect is poor. The 5-year survival rate is about 10%, and the median survival time is 7 to 9 months 1. Accurate pathological diagnosis and prognosis analysis are very important for patients to choose the most appropriate treatment. Therefore, it is urgent to make a fuller understanding of diffuse pleural mesothelioma on the basis of existing pathological research and clinical research evidence, so as to improve the level of standardized clinical diagnosis and treatment.
ABSTRACT
Objective:To observe the surgical method and clinical efficacy of applying calf tissue flap combined with artificial bone of antibiotics loaded calcium sulphate in treatment of tibia osteomyelitis.Methods:From July 2018 to January 2021, calf tissue flaps combined with artificial bone of antibiotics loaded calcium sulphate (or mixed with iliac bone) were applied to treat 16 cases with tibia osteomyelitis in the Department of Hand and Microsurgery of Baoji Third Hospital. There were 10 males and 6 females, aged 15 to 64 years old, with a mean age of 41 years old. For the 5 cases with acute osteomyelitis caused by wound infection, local dressing changes and drainage or VSD wound management were applied after debridement, together with primary systemic anti-infection treatment. After the acute infection period had been under control and stabilised, the wounds were then thoroughly exposed and cavities were filled and covered with the surgical reconstruction procedure with antibiotics-loaded artificial bone of calcium sulphate in combination with calf tissue flaps. For the 11 cases with chronic and hypotoxicity osteomyelitis, calf tissue flaps combined with antibiotics-blended artificial bone of calcium sulphate were applied to fill the cavity and cover the wound in phase I surgical reconstruction after thorough debridement. For the 7 cases with large bone defects or larger cavities after debridement, a mixed bone grafts of antibiotics-loaded artificial bone of calcium sulphate and autologous iliac bone were employed, with muscle flaps or myocutaneous flaps for an embedding repair. Sizes of the tissue flaps were 2.0 cm×3.5 cm to 12.0 cm×23.0 cm. Clinical outcomes were evaluated through follow-ups at outpatient clinic. The therapeutic effect was evaluated by the method described by McKee et al.Results:Except for 1 case of distal necrosis of tissue flap and survived after dressing change, the other tissue flap survived successfully. Postoperative follow-ups lasted for 12 to 40(mean 18) months. All the osteomyelitis were successfully cured, except 1 that had recurrence of osteomyelitis 1 year later, and treated with antibiotics-loaded artificial bone of calcium sulphate combined with autologous iliac bone implants after thorough debridement, and then healed well. The shape and texture of flaps were good. Protective sensations were restored to vary levels after 6 months. The calf regained weight-bearing and walking functions at 1 year after surgery. According to McKee et al., the therapeutic effect was evaluated: 11 cases were cured, 4 cases were improved, and 1 case relapsed, with an effective rate of 93.8%.Conclusion:Application of calf tissue flap combined with antibiotics-loaded artificial bone of calcium sulphate in the treatment of tibia osteomyelitis has a high cure rate and remarkable efficacy. It can significantly reduce the number of surgeries and shorten the course of disease.

ABSTRACT
COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.
ABSTRACT
Objective:To study the value of myocardial perfusion imaging (MPI) and coronary flow reserve (CFR) combined with coronary artery calcium score (CACS) in the diagnosis of obstructive coronary artery disease (CAD).Methods:From January 2019 to December 2020, 96 confirmed or suspective CAD patients (65 males, 31 females; age: 30-81 years) who completed rest/stress MPI, CFR and CACS defection in Fuwai Central China Cardiovascular Hospital were retrospectively analyzed. Coronary angiography (CAG) was used as the diagnostic standard to calculate the sensitivity and accuracy of MPI, CFR and MPI/CFR combined with CACS in the diagnosis of CAD. The χ2 test was used to compare the diagnostic efficiency of different methods. Results:The diagnostic sensitivity of MPI was 76.06%(54/71), and the accuracy was 75.00%(72/96), while the sensitivity increased to 97.18%(69/71; χ2=13.67, P<0.001) and the accuracy increased to 87.50%(84/96; χ2=4.92, P=0.020) with significant differences after combined with CACS. The sensitivity and accuracy of CFR were 91.55%(65/71)and 87.50%(84/96), which increased to 97.18%(69/71; χ2=2.12, P=0.137) and 89.58%(86/96; χ2=0.21, P=0.411) with no significant differences after combined with CACS. The sensitivity of MPI in the diagnosis of three-vessel CAD was 70.00%(21/30), which increased to 100%(30/30; χ2=7.75, P=0.004) after combined with CACS; while the sensitivity of MPI combined with CACS in the diagnosis of single-vessel and double-vessel CAD were not significantly improved ( χ2 values: 3.29, 1.51, P values: 0.114, 0.416). Conclusion:The combination of MPI and CACS can significantly improve the diagnostic efficiency of CAD, contributed by the improvement of the diagnostic sensitivity in three-vessel disease; whereas the diagnostic efficiency of CFR for CAD is not significantly improved after combined with CACS.
ABSTRACT
OBJECTIVE@#This study prospectively investigates the association between immunoglobulin G (IgG) N-glycan traits and ischemic stroke (IS) risk.@*METHODS@#A nested case-control study was conducted in the China suboptimal health cohort study, which recruited 4,313 individuals in 2013-2014. Cases were identified as patients diagnosed with IS, and controls were 1:1 matched by age and sex with cases. IgG N-glycans in baseline plasma samples were analyzed.@*RESULTS@#A total of 99 IS cases and 99 controls were included, and 24 directly measured glycan peaks (GPs) were separated from IgG N-glycans. In directly measured GPs, GP4, GP9, GP21, GP22, GP23, and GP24 were associated with the risk of IS in men after adjusting for age, waist and hip circumference, obesity, diabetes, hypertension, and dyslipidemia. Derived glycan traits representing decreased galactosylation and sialylation were associated with IS in men (FBG2S2/(FBG2 + FBG2S1 + FBG2S2): odds ratio ( OR) = 0.92, 95% confidence interval ( CI): 0.87-0.97; G1 n: OR = 0.74, 95% CI: 0.63-0.87; G0 n: OR = 1.12, 95% CI: 1.03-1.22). However, these associations were not found among women.@*CONCLUSION@#This study validated that altered IgG N-glycan traits were associated with incident IS in men, suggesting that sex discrepancies might exist in these associations.
