Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population. Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort. Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95％CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95％CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95％CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95％CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95％CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95％CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95％CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Cox model with forward stepwise selection, triglycerides were the only lipid markers entered into the final model. Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.

Platelet-derived growth factor receptor beta (PDGFRB) rearrangements play an important role in the pathogenesis of eosinophilia-associated myeloid/lymphoid neoplasms. Up to now, more than 70 PDGFRB fusions have been identified. Here, a novel PDGFRB fusion gene CSNK2A1-PDGFRB has been identified in myeloproliferative neoplasm (MPN) with eosinophilia by RNA-sequencing, which has been verified by reverse transcription polymerase chain reaction and Sanger sequencing. The new PDGFRB fusion partner gene CSNK2A1 encoded one of the two catalytic subunit of casein kinase II (CK2). To our knowledge, this is the first report on the involvement of CSNK2A1 in fusion genes, especially fusion with another kinase PDGFRB in MPN. In addition, the CSNK2A1-PDGFRB fusion retained the entire kinase domain of PDGFRB and response to imatinib at low concentration. The patient with CSNK2A1-PDGFRB was sensitive to imatinib treatment and acquired sustained complete remission.

Objective:To investigate the application value of dual-source CT urography with stellar photon detectors in the diagnosis of gout.Methods:Forty patients who were diagnosed with gout according to American College of Rheumatology Guideline for the Diagnosis of Gout and received treatment between April 2018 and May 2020 were included in the observation group. Forty patients who were concurrently diagnosed with osteoarthritis and received treatment in the same hospital were included in the control group. All patients underwent dual-source CT urography with stellar photon detectors and corresponding biochemical index detection. Blood levels of uric acid, urea nitrogen, creatinine, total cholesterol, and triglyceride were compared between the observation and control groups.Results:Blood levels of uric acid, creatinine, urea nitrogen, total cholesterol, and triglyceride in the observation group were (519.38 ± 97.91) μmol/L, (110.21 ± 18.29) μmol/L, (12.21 ± 3.29) mmol/L, (6.49 ± 1.22) mmol/L, (3.45 ± 1.89) mmol/L, respectively, which were significantly higher than those in the control group (310.45 ± 61.40) μmol/L, (86.22 ± 13.12) μmol/L, (6.82 ± 1.75) mmol/L, (4.75 ± 0.56) mmol/L, (1.98 ± 0.85) mmol/L, respectively ( t = 11.43, 6.741, 9.148, 8.198, 4.486, all P < 0.05). Dual-source CT urography with stellar photon detectors revealed that urate crystals (color coded as green) were detected in 3 and 36 patients from the control and observation groups, respectively, with the detection rate of 7.5% (3/40) and 90% (36/40), respectively. There was significant difference in urate crystal detection rate between the observation and control groups ( χ2 = 24.993, P < 0.05). In the control group, no obvious destruction of bone, tendon and ligament were observed, urate deposition, total volume of (1.023 ± 0.83) cm 3, was found in feet and knee joint of a small number of patients. In the observation group, there were 30 patients with uric acid crystals and bone destruction in the metatarsophalangeal joint ( n = 6), distal tibia ( n = 7), distal fibula ( n = 3), proximal talus ( n = 4), proximal calcaneus ( n = 6), and wrist joint ( n = 4). There were 20 patients with ligament or tendon damage, involving deltoid ligament ( n = 2), Achilles tendon ( n = 10), and extensor and flexor tendon ( n = 53). Total volume of uric acid crystals was (32.22 ± 5.83) cm 3. The volume of uric acid crystals deposited in the hand, elbow, feet and knee was (8.00 ± 4.92) cm 3, (5.32 ± 2.75) cm 3, (36.00 ± 15.54) cm 3, and (13.31 ± 9.14) cm 3, respectively. Conclusion:Dual-source CT urography with stellar photon detectors has a high sensitivity in the diagnosis of gout, can accurately locate and quantify uric acid crystals and is of high application value in the diagnosis of gout.

Objective:To investigate the serotypes and antimicrobial resistance of seven invasive non-typhoidal Salmonella (iNTS) isolates. Methods:For 7 iNTS strains collected, serotype identification, antimicrobial susceptibility testing and whole genome sequencing were performed. We identified, annotated and analyzed the serotypes, MLST types, and antimicrobial resistance genes.Results:Among the 7 tested iNTS isolates, we found one Salmonella Typhimurium strain and two Salmonella Ⅰ 4, [5], 12: i:- strains whose MLST types were ST34, two Salmonella Enteritidis strains, one Salmonella Corvallis strain and one strain of unknown serotype with the antigenic formulae of Ⅰ 4, [5], 12: d:- (ST279 type). Six of seven strains were monophasic and the deletion or pseudogenization of Salmonella Flagellum gene might contribute to the enhancement of Salmonella invasiveness. None was found to be resistant to tigarcycline, aztreonam, amikacin, cephalosporins and carbapenem and one Salmonella Typhimurium strain was found to be co-resistant to eight classes of antimicrobials at the same time. Resistance genes were generally in accord with relative resistant phenotypes. Conclusion:The iNTS strains could show high level multi-drug resistance, indicating that close attention should be paid to the resistance of iNTS though the overall resistance might be relatively not high.

OBJEVTIVETo investigate the expression of transient receptor potential lvanilloidreceptor 4 (TRPV4) protein in pemphigus vulgaris (PV), bullous pemphigoid (BP), dermatitis herpetiformis (DH), and epidermolysis bullosa acquisita (EBA), and explore the role of TRPV4 in the pathogenesis of these diseases.

METHODSTRPV4 protein in normal skin tissues and lesions of PV, BP, DH, and EBA were detected with immunohistochemistry.

OBJECTIVETo investigate the effects of topical treatment with adenovirus-mediated promyelocytic leukemia gene (PML) gene in a psoriasis-like mouse model.

METHODSThe effect of adenovirus-mediated PML gene on the granular layer of mouse tail scale epidermis and epithelial mitosis were observed on longitudinal histological sections prepared from the tail skin and vaginal epithelium of the mice.

RESULTSAdenovirus-mediated PML gene significantly inhibited mitosis of mouse vaginal epithelial cells and promoted the formation of granular layer in mouse tail scale epidermis.

CONCLUSIONThe therapeutic effect of PML gene in the psoriasis-like mouse model may be associated with increased granular cells and suppressed epidemic cell proliferation.

OBJECTIVETo investigate the expression of promyelocytic leukaemia (PML) protein of PML protein in Bowen's disease (BD), skin squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) and explore the role of PML in the pathogenesis of these diseases.

METHODSPML protein in normal skin tissues and lesions of Bowen's disease, SCC and BCC were detected with immunohistochemistry.

RESULTSNormal skin tissues did not express PML protein. In BCC, PML showed rather low expressions in the skin lesions (8.69% in cell nuclei and 4.35% in cytoplasm). The lesions in BD and SCC (grade I and II) showed obvious overexpression of PML protein in the cell nuclei and cytoplasm, and its expression in the cell nuclei of these lesions was significantly higher than that in grade III-IV SCC.

CONCLUSIONPML protein may play an important role in the early stage of SCC, and its overexpression may contribute to the carcinogenesis and metastasis of SCC.
