Objective To explore the probability and associated factors of pulmonary fibrosis in 350 cases of elderly pneumonia. Methods Elderly patients who received diagnosis and treatment at Changzhi Medical College Affiliated Peace Hospital from January 2018 to December 2022 were selected, and 350 patients who met the criteria were included in the study. Analyze its clinical data, incidence of pulmonary fibrosis, and analyze the relationship between the two. Results The average age of 350 patients was (63.51 ± 5.74) years old; 219 cases were common type , 72 cases were severe type, and 59 cases were critically ill. At admission, the CT signs were: ground glass in 66 cases (18.86%) , paving stone in 37 cases (10.57%), consolidation in 73 cases (20.86%), nodules in 93 cases (26.57%) , fried egg sign in 20 cases (5.71%) , and mosaic sign in 61 cases (17.43%). At discharge, the lesion signs were as follows: 61 cases (17.43%) had no lesions, 207 cases (59.14%) maintained the original lesion signs, and 82 cases (23.43%) evolved into other signs. 76 cases of pulmonary fibrosis were discharged, with an incidence rate of 21.71%. There were significant differences in the incidence of pulmonary fibrosis among patients with different ages, lesion evolution during treatment, lesion signs at discharge, and clinical stages (all P<0.001). Pulmonary fibrosis is positively correlated with age (P=0.047), lesion signs at discharge (P=0.032), and clinical classification (P=0.010). The incidence of lesions presenting as paving stones (P=0.014) and fibrosis in critically ill patients (P=0.013) at discharge is higher. Age increase (P=0.047) , wide range of lesions at admission (P=0.042), evolution of lesions into other signs at discharge (P=0.016), and clinical classification as severe (P=0.008) or critically ill (P=0.021) are independent risk factors for the development of pulmonary fibrosis in elderly pneumonia patients. Conclusion The incidence of pulmonary fibrosis in elderly patients exceeds 20%. Increasing age, wide range of lesions upon admission, evolution of lesions into other signs upon discharge, and clinical classification as severe or critically ill are independent risk factors for the occurrence of pulmonary fibrosis in elderly pneumonia patients.

OBJECTIVE To observe the efficacy of vericiguat in the treatment of acute decompensated heart failure (HF) and its effect on left ventricular ejection fraction (LVEF) in patients with different left ventricular end-diastolic internal diameters (LVDd). METHODS A total of 52 patients with acute decompensated HF who were hospitalized in Anqing Municipal Hospital from September 2022 to May 2023 and were stabilized by intravenous injection of diuretics or vasodilators and then given vericiguat orally were selected. Clinical baseline data were collected, and blood creatinine (Scr), estimated glomerular filtration rate (eGFR), N-terminal pro-B-type natriuretic peptide (NT-proBNP), echocardiographic indexes(LVEF, LVDd), and Kansas City cardiomyopathy questionnaire (KCCQ) scores and so on were recorded and analyzed at 1 and 6 months after treatment. The patients were divided into two subgroups according to whether they had dilated cardiomyopathy or not, the baseline data were compared between the two subgroups, and the changes in the above follow-up indexes for the entire population and two subgroups of patients were analyzed by using mixed effect model. RESULTS Patients in the dilated cardiomyopathy group were significantly younger than those in the nondilated cardiomyopathy group, while the former had a lower proportion of patients with combined coronary artery disease, longer LVDd, lower LVEF levels, and more HF patients with reduced ejection fraction (P<0.05). Compared with baseline values, KCCQ scores were significantly higher in patients in the whole population, non-dilated cardiomyopathy group and dilated cardiomyopathy group at 1 month after treatment (P<0.001). The difference between the whole population in terms of elevated KCCQ scores and decreased lg(NT-proBNP) levels was statistically significant at 6 months after treatment (P<0.05); the levels of lg(NT-proBNP)of two subgroups were significantly decreased and KCCQ scores were significantly increased (P<0.05), but the difference was not statistically significant (P>0.05); LVEF levels of the patients E-mail:guangf4-508@163.com in both subgroups were significantly elevated (P<0.05) and the difference between the subgroups amounted to 7.52% (P=0.030). Mixed effect model result showed that whether patients had coronary artery disease and different baseline levels of LVDd were likely to affect follow-up LVEF levels, with coronary artery disease contributing to follow-up LVEF elevation (P=0.043), but the coronary artery disease subgroup × time interaction was not significant (P>0.05);compared with patients with baseline LVDd ≥62 mm, patients with baseline LVDd≤61 mm had a faster LVEF improvement (P<0.05). CONCLUSIONS Vericiguat is able to improve cardiac function and quality of life in patients with acute decompensated HF without negatively affecting their renal function. The drug is able to significantly improve LVEF levels in patients with baseline LVDd ≤61 mm.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To observe the expression of angiopoietin-like protein 4 (ANGPTL4) signaling pathway in adenine-induced chronic kidney disease (CKD) rat model, and to explore the role of this pathway in renal fibrosis.Methods:Thirty-six male Sprague-Dawley rats were randomly divided into control group (saline, intragastric administration, n=15) and CKD group (250 mg·kg -1·d -1 2.5% adenine, intragastric administration, n=21). At the end of the 1st, 2nd and 4th week, 5 rats were randomly selected from each group. Renal function and 24-hour urinary protein quantity were measured. HE and Masson staining were used to observe the pathological changes of kidneys. Immunohistochemistry and real-time PCR were used to detect renal protein and mRNA expressions of hypoxia-inducible factor-1α (HIF-1α), ANGPTL4, bone morphogenetic protein 7 (BMP7), Smad1, α-smooth muscle actin (α-SMA) and type Ⅰ collagen (Col-Ⅰ). Pearson correlation analysis was used to analyze the correlation between the different indicators. Results:(1) Compared with the control group, the expression levels of serum creatinine and blood urea nitrogen in CKD group were higher at each time point, and the expression levels of 24-hour urinary protein quantity were higher at the end of the 2nd and 4th week (all P < 0.05). (2) HE and Masson staining showed that there were obvious renal structural disorders and collagen fiber deposition at each time point in CKD group compared with the control group, which got worse with time. (3) The results of immunohistochemistry and real-time PCR showed that compared with the control group, the protein and mRNA expression levels of ANGPTL4, α-SMA and Col-Ⅰ were higher, while the protein and mRNA expression levels of BMP7 and Smad1 were lower at the end of the 1st, 2nd and 4th week, and the protein and mRNA expression levels of HIF-1α were higher at the end of 2nd and 4th week in CKD group (all P < 0.05). (4) Correlation analysis results showed that HIF-1α and ANGPTL4 mRNA expression were positively correlated with α-SMA mRNA ( r=0.919, P < 0.001; r=0.757, P < 0.001), and also positively correlated with Col-Ⅰ mRNA ( r=0.925, P < 0.001; r=0.777, P < 0.001). HIF-1α mRNA expression was positively correlated with ANGPTL4 mRNA ( r=0.766, P < 0.001). There were significant negative correlations between HIF-1α, ANGPTL4 mRNA and BMP7 mRNA ( r=-0.652, P < 0.001; r=-0.741, P < 0.001). Conclusions:ANGPTL4 signaling pathway may be activated in adenine-induced CKD rat model, and involved in the renal fibrosis process of CKD.

Objective:To analyze the changes in serum metabolites of patients with uremia using ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS), and provide a theoretical basis for the prevention and treatment of uremia.Methods:Uremia patients from the Department of Nephrology, the Affiliated Hospital of Southwest Medical University, and the volunteers from the Health Examination Center were enrolled in this study. According to the inclusion and exclusion criteria, 20 uremia patients (experimental group) and 20 volunteers (control group) were screened out. UHPLC-MS was used to detect the metabolites in the serum of subjects from the two groups, and difference analysis was made to screen the different metabolites, followed by correlation analysis and pathway enrichment study.Results:A total of 412 metabolites were identified by UHPLC-MS. Principal components analysis (PCA) proved that these metabolites could distinguish the control group and the experimental group well. The criteria [variable importance for the projection (VIP)>1, fold changes (FC)>1.25 or FC<0.8 and P value<0.05] was set to screen those significantly different metabolites. Finally, 28 significantly different metabolites were screened out, of which 18 metabolites increased significantly, the other 10 different metabolites decreased significantly. Correlation analysis results proved a certain correlation among 28 different metabolites and the experimental group and control group samples, and between the 28 differential metabolites themselves. Enrichment analysis found that 28 different metabolites might enrich the catecholamine biosynthetic pathway, and pathway analysis suggested that 28 different metabolites might affect glutamate, aspartame acid and glutamate metabolic pathways. Conclusion:Based on metabonomic analysis, some metabolites in the serum of patients with uremia have changed, which can affect some metabolic pathways, thus affecting the pathophysiological process of patients with uremia.
摘要
Angioimmunoblastic T-cell lymphoma (AITL) is one of the most common subtypes of peripheral T-cell lymphomas. It is a fol-licular T-helper-derived neoplasm, and characterized by the presence of some genetic alterations, such as mutations in TET2, DN-MT3A, IDH2, and RHOA. Anthracycline-containing regimens represent the most widely adopted first-line option; however, new biolog-ic agents should be designed and incorporated to improve treatment response. The elucidation of the specific roles of these genetic al-terations in AITL will facilitate the development of molecularly targeted therapies to treat this disease.

Objective To compare the differences in cognitive function and behavioral and psychological symptoms between patients with Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD). Methods Thirty-six AD patients and 20 bvFTD patients at mild-to-moderate stage, who were biomarker-confirmed by positron emission tomography (PET), were assessed with a neuropsychological battery and neuropsychiatry inventory (NPI). Cognitive domains, including memory, language, information processing speed and executive function, and behavioral and psychological symptoms were assessed and compared. Results AD patients had lower scores in immediate recall, delayed recall and recognition than bvFTD patients (all P<0.05); while bvFTD patients had poorer performance in language and executive function than AD patients (all P<0.05). The NPI total score was significantly higher in patients with bvFTD compared with patients with AD (17.5±5.7 vs 9.3±3.5, P<0.05). In respect to the 12 items of NPI, the incidence of agitation and irritability was higher in AD group than in bvFTD group (72.2%vs 35.0%, 55.6%vs 20.0%, all P<0.05);while the incidence of apathy, disinhibition, euphoria, aberrant motor behavior and appetite/eating was higher in bvFTD group than in AD group (65.0%vs 33.3%, 80.0% vs 5.5%, 70.0% vs 5.6%, 40.0% vs 11.1%, 50.0% vs 5.6%, all P<0.05). Conclusion Comprehensive neuropsychological assessment and evaluation of behavioral and psychological symptoms of patients with dementia are helpful in distinguishing AD from bvFTD.

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P < 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps < 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps > 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps < 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P < 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.

Objective To study the clinical significance ofneutrophil gelatinase-associated lipocalin (NGAL), which in serial plasma and urine samples was measured in participants with lupus nephritis (LN)and healthy persons. Methods NGAL in serial plasma and urine samples was measured by enzyme-linked immunosorbent assay (EL.ISA) in 35 patients with LN by 1997 ACR systemic lupus erythematosus (SLE)standard with varied degree of kidney damage and 30 healthy persons with matching sex and age in physical examination center. Disease activity was measured by the SLE disease activity index (SLEDAI-2K),and 35LN patients were classified in active group and (25 cases) non-active group (10 cases) according to the SLEDAI-2K. Results Urinary NGAL were significantly increased in LN patients [(78.94 ± 81.97) μg/L]compared with healthy persons[(28.50 ± 18.08) μ g/L] (P = 0.002). And urinary NGAL were significantly increased in active group [(92.90 ± 94.88) μg/L] compared with non-active group [(48.20 ± 24.77)μ g/L] (P = 0.049). NGAL in serial plasma had no statistically significant difference between active group and non-active group (P >0.05). Conclusions NGAL in urine but not in plasma represents a novel biomarker for renal disease activity in LN. The increase might be related to renal tubule pathological changes.

To study action mechanism and time of administration of indomethacin in SMAO shock rabbits. Method:Thirty-two SMAO shock rabbits were randomly divided into four groups: control group A,indomethacin 5mg/kg I.V. at the occlusion of superior mesenteric artery (group B), indomethacin 5mg/kg L V. immediately after clamp being removed(group C) and the same dose 30min after clamp being removed(group D). Survival rate,hemodynamics, plasma calcium, myocardial calcium, TXB_2 and 6-keto-PGF_1. levels were observed in 4h shock period. Myocardial apecmen were examined with electronic microscope. Result: After indomethacin I.V,the survival rate was higher and bemodynamie better than those of controll. The plasma calcium level remained stable in indomethacin groups. Myocardial calcium content of group B and C was lower than that of group D and A. The TXB_2 and 6-ketoPGF_1. contents were similar in all groups. Under electronic microscope, the damages were slightest in group C and most serious in group D and A among the four groups. Conclusion:Indomethacin has a beneficial effect on the SMAO shock rabbits ,the mechanism of which can be related to improving myocardium contractivity as well as to blocking calcium channel,rather than the action through prostaglandins. The time of administration should be early as possible after shock.
