Objective To investigate the effect of employing achievement management in nursing management of urology department.Method The results of assessments were linked to the achievements by regulating achievement-oriented distribution and assessment methods.Results The degree in patients' satisfaction with nursing service and the score on nursing quality assessment were both significantly improved compared to pre-performance of achievement-oriented distribution and assessment(P<0.01). Conclusion The achievement-oriented management may be effective in mobilizing nurses' working enthusiasm and increase quality of care,which guarantees fundamental nursing care.

OBJECTIVETo investigate the effects of advanced oxidation protein products (AOPP) on epithelial-to-mesenchymal transition (EMT) in cultured human proximal tubular epithelial cells (HK-2) and explore the mechanism.

METHODSHK-2 cells treated with 50, 100, 200, and 400 µg/ml AOPP or 50 µg/m bovine serum albumin (BSA) for 24 h, or with 200 µg/ml AOPP for 0.5, 1, 3, 6, 12, and 24 h were examined for the protein expression of α-SMA and E-cadherin. In cells pretreated with diphenyleneiodonium (DPI) or cytoplasmic superoxide dismutase (C-SOD), the effects of 50 µg/ml BSA and 200 µg/ml AOPP were assessed on the expressions of α-SMA and E-cadherin, malondialdehyde (MDA) level, superoxide dismutase (SOD) activity, catalase (CAT) activity, and glutathione peroxidase (GSH-px) activity.

RESULTSAOPP treatment up-regulated α-SMA expression and down-regulated E-cadherin expression in a dose- and time-dependent fashion. AOPP exposure of the cells resulted in increased MDA level and lowered activities of SOD, CAT and GSH-PX. DPI and C-SOD partially attenuated the effects of AOPP on α-SMA, E-cadherin, MDA, SOD, CAT and GSH-px.

CONCLUSIONAOPP can induce EMT in cultured HK-2 cells via oxidative stress, and this effect can be attenuated by inhibiting the activation of NADPH oxidase and using antioxidants to delay the progression of renal interstitial fibrosis.

OBJECTIVETo investigate the association between single nucleotide polymorphisms (SNPs) of the transmembrane protein 39A (TMEM39A) at the loci 1880G/A, 2442T/G, and 2456A/T and systemic lupus erythematosus (SLE) in Chinese Han patients.

METHODSTMEM39A gene polymorphisms at 3 loci (1880G/A, 2442T/G, 2456 A/T) were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 110 Chinese Han patients with SLE and 80 normal control subjects, and the allele and genotype frequencies were compared by Chi-square test between the two groups.

RESULTSBoth the genotype frequencies (AA, GA and GG) and allele frequencies (A and G) at 1880G/A differed significantly between SLE cases and the normal controls (P=0.002 and P=0.044, respectively). The two groups also showed significant differences in the genotype frequencies (GG, TG and TT) (P=0.001) and allele frequencies (G and T) (P=0.041) at 2442T/G. No significant differences were found in the genotype frequencies (TT, AT and AA) or allele frequencies (T and A) at 2456A/T between the two groups (P>0.05). The allele and genotype frequencies of the 3 SNPs showed no significant differences between lupus nephritis (LN) patients and non-LN patients.

CONCLUSIONThe TMEM39A polymorphisms at 1880G/A and 2442T/G, but not at 2456 A/T gene, may be associated with the susceptibility to SLE in Chinese Han population. The genotype or allele frequencies of the 3 SNPs have no effect on the incidence of lupus nephritis.

Objective: To explore the efficacy and safety of chimeric antigen receptor T (CAR-T) cells in the treatment of central nervous system leukemia (CNSL). Methods: Two leukemia patients with CNSL were treated with CD19-CAR-T cells. The process and results of the entire treatment is reported and related literature review is conducted. Results: The patients were diagnosed as acute myeloid leukemia (AML)-M₂ with B lymphoid antigen expression and B cell acute lymphoblastic leukemia(B-ALL) by morphology and immunophenotype assay. The immunophenotype was consistent with the abnormal manifestations of AML-M₂ and B-ALL. Their clinical manifestations and laboratory tests met the diagnostic criteria of CNSL. The diagnosis was clear and the two patients were treated with CD19-CAR-T cell immunotherapy. Central nervous system symptoms were relieved. The imaging abnormalities of patient one has disappeared but cytokines release syndrome (CRS) occurred during the treatment. Cerebrospinal fluid of patient two was negative and no obvious CRS reaction was found. Conclusions CAR-T cell immunotherapy is likely to induce the remission of CNSL and improve the prognosis.

Objective:To detect the abnormal changes of myocardial blood perfusion in patients with hypertrophic cardiomyopathy (HCM) by myocardial contrast echocardiography(MCE) combined with exercise stress test.Methods:Twenty-seven patients with clinically diagnozed of asymmetric HCM in Fuwai Central China Cardiovascular Hospital from May 2020 to April 2021 were selected as the HCM group, and 29 healthy subjects during the same period were selected as the control group. All patients underwent routine echocardiography, resting and exercise stress MCE. The myocardial perfusion parameters of each segment of interventricular septum in the 2 groups were quantitatively analyzed: the peak plateau intensity (A value), ascending slope of the curve(β value) and value of A×β. According to the end-diastolic myocardial thickness, the interventricular septum of the HCM group was divided into hypertrophic and non-hypertrophic segments, and the myocardial contrast parameters of the interventricular septum of the study group were compared with those of the control group. The myocardial blood flow reserve value of the two groups were calculated, and the correlation of myocardial blood flow reserve value with left ventricular mass index (LVMI) and left ventricular remodeling index (LVRI) were analyzed.Results:No matter at rest or under stress, the A value, β value and A×β value of ventricular septal hypertrophic and non-hypertrophic segments in the hypertrophic cardiomyopathy group were lower than those in the control group, and the differences were statistically significant (all P<0.05). Under stress, the A value, β value and A×β value of interventricular septal hypertrophic segments were lower than those in non-hypertrophic segments in the HCM group, and the differences were statistically significant (all P<0.05). The myocardial blood flow reserve in the HCM group was negatively correlated with LVMI and LVRI( r=-0.899, -0.676; all P<0.001). Conclusions:In patients with HCM under resting and exercise stress, microcirculation disorders were found in both hypertrophic and non-hypertrophic segments of the ventricular wall, and the myocardial blood flow reserve was negatively correlated with LVMI and LVRI.
