Proteus mirabilis is a gram-negative rod-shaped bacterium that can cause urinary tract infections, bloodstream infections and gastrointestinal infections. Urinary tract infections caused by Proteus mirabilis are hard to be treated and pose a serious public health problem. With the use of antimicrobial drugs for clinical treatment, the resistance rates of Proteus mirabilis to β-lactams and quinolones increase. Besides the unregulated use of antimicrobial drugs contributes to the emergence of multidrug-resistant Proteus mirabilis and carbapenem-resistant Proteus mirabilis. In this review, we will discuss Proteus mirabilis-related clinical infections, and the epidemiological characteristics and β-lactam resistance mechanism, hoping to provide ideas for the treatment and prevention of Proteus mirabilis infections in the future.

Systemic mastocytosis (SM) with RUNX1-RUNX1T1 positive acute myeloid leukemia (AML) is a rare myeloid tumor with no standard treatment. Two cases of SM patients with RUNX1-RUNX1T1 positive AML treated with sequential avapritinib after allogeneic hematopoietic stem cell transplantation (allo-HSCT) were reported in Henan Cancer Hospital. Mast cell in bone marrow disappeared, C-KIT mutation and RUNX1-RUNX1T1 fusion gene remained negative. Allo-HSCT sequential avapritinib is an effective treatment for SM patients with RUNX1-RUNX1T1 positive AML.

Objective:To investigate the efficacy and safety of avapritinib in the treatment of molecular biologically positive core binding factor-acute myeloid leukemia (CBF-AML) with KIT mutation after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:We retrospectively analyzed the clinical data of six patients with molecular biologically positive CBF-AML with KIT mutation after allo-HSCT, who were treated with avapritinib at Henan Cancer Hospital from December 2021 to March 2023, and evaluated the efficacy and safety of avapritinib.Results:After 1 month of treatment with avapritinib, the transcription level of the fusion gene decreased in six patients, and the transcription level decreased by ≥1 log in five patients. In four patients who received avapritinib for ≥3 months, the fusion gene turned negative, and the median time to turn negative was 2.0 (range: 1.0-3.0) months. Up to the end of follow-up, four patients had no recurrence. The most common adverse reaction of avapritinib was myelosuppression, including neutropenia in two cases, thrombocytopenia in two cases, and anemia in one case. The non-hematological adverse reactions were nausea in two cases, edema in one case, and memory loss in one case, all of which were grades 1-2.Conclusion:Avapritinib was effective for molecular biologically positive CBF-AML patients with KIT mutation after allo-HSCT. The main adverse reaction was myelosuppression, which could generally be tolerated.

Background and purpose:Esophageal carcinoma(ESCA)is one of the malignant tumors with high mortality rate,and the underlying mechanism of its development is largely unknown.CDC20 plays an important role in tumorigenesis,and its dysregulated expression is closely related to tumor occurrence and development.The expression of CDC20 is increased in a variety of tumors,and knocking down CDC20 can inhibit tumor cell proliferation.NLRP3 is the main component of the inflammasome,and inflammasome is also closely related to tumor occurrence and development.Here,our study aimed to investigate whether CDC20 promotes the proliferation of ESCA cells through NLRP3 and its regulatory mechanism.Methods:The expression levels of CDC20 and NLRP3 genes in ESCA patients were analyzed using The Cancer Genome Atlas(TCGA)detabase and GTEx public database.We collected clinical and pathological data and tissues from 80 ESCA patients at the First Affiliated Hospital of Xinxiang Medical College,and detected the protein expression of NLRP3 in ESCA patients through immunohistochemistry staining.This study was approved by the Ethics Committee of the First Affiliated Hospital of Xinxiang Medical College(Number:EC-021-137).We studied the effects of knocking down CDC20 and NLRP3 gene on the proliferation ability of esophageal squamous cell carcinoma cells EC9706 and KYSE150 using short hairpin RNA(shRNA)technology.Co-immunoprecipitation(Co-IP),proteasome inhibitors and ubiquitination experiments were used to detect whether CDC20 interacts with NLRP3,and to elucidate whether CDC20 regulates NLRP3 expression through the ubiquitination pathway.This study was approved by the Ethics Committee of the First Affiliated Hospital of Xinxiang Medical College(Number:EC-021-137).Results:The TCGA database analysis showed that the expression levels of CDC20 and NLRP3 mRNA were significantly higher in the cancer tissues of ESCA patients than in the adjacent tissues.The immunohistochemistry results further showed that compared with adjacent tissues,the protein expression levels of CDC20 and NLRP3 were increased in ESCA tissues.Knocking down CDC20 and NLRP3 genes inhibited the proliferation of ESCA cells.Co-IP,proteasome inhibitors and ubiquitination experiments confirmed that CDC20 interacted with NLRP3 through its leucine-rich repeat(LRR),and CDC20 stabilized its expression by promoting NLRP3 ubiquitination.Conclusion:CDC20 and NLRP3 are upregulated in ESCA tissues,and CDC20 stabilizes their expression through ubiquitination of NLRP3,promoting ESCA cell proliferation.This suggests that CDC20 and NLRP3 may be potential diagnostic targets for ESCA.

OBJECTIVE To investigate the clinical effect of Budigafol combined with Staphylococcus and neisseria tablets in maintenance treatment of patients with stable moderate to severe chronic obstructive pulmonary disease (COPD). METHODS A total of 122 patients with stable moderate to severe COPD who were admitted to the infections diseases ward of the department of respiratory and critical care medicine in our hospital from October 1, 2021 to January 31, 2023 were divided into control group (n=61) and observation group (n=61) according to the random number table method. Patients in the control group were treated with Budigafol inhalation aerosol alone (2 presses each time, twice a day), and patients in the observation group were treated with Staphylococcus and neisseria tablets (1.2 mg each time, 3 times a day) on the basis of the control group. The treatment course of both groups was 3 months. The quality of life, exercise tolerance, lung function, inflammatory indexes, immune function, as well as the number of acute attacks of COPD and the occurrence of adverse reactions were compared between the two groups before and after treatment. RESULTS Control group and observation group shed 12 and 9 patients, respectively. After treatment, the 6 minute walking distance of the two groups of patients was significantly prolonged compared with that before treatment (P<0.05). The COPD assessment test questionnaire score, St George’s respiratory questionnaire score, the ratio of residual volume to total lung capacity, the fractional exhaled nitric oxide, the serum levels of C-reactive protein and interleukin-6 were significantly E-mail:13956685295@163.com decreased compared with those before treatment (P<0.05). The forced expiratory volume in one second (FEV1), the ratio E-mail:13966580920@163.com of FEV1 to forced vital capacity, the percentage of the measured value of carbon monoxide diffusion capacity to the predicted value, and the percentage of the measured value of FEV1 to the predicted value were significantly increased compared with those before treatment (P<0.05). The improvement of the above indicators in the observation group was significantly better than that in the control group (P<0.05). Compared with before treatment, there was no statistical significance in the immune function indexes of the control group or the serum levels of immunoglobulin A (IgA) and IgM in the observation group after treatment (P>0.05). The percentages of CD3+ , CD4+ , B lymphocytes and natural killer cells, the levels of CD4+/CD8+ and IgG were significantly increased in the observation group (P< 0.05), the percentage of CD8+ cells was significantly decreased (P<0.05), and the improvement degree of the observation group was significantly better than that of the control group (P<0.05). There was no significant difference in the number of acute exacerbations of COPD during the follow-up period and the incidence of adverse events during treatment between the two groups (P>0.05). CONCLUSIONS Budigafol combined with Staphylococcus and neisseria tablets can effectively improve the immune function of patients with stable moderate to severe COPD, further reduce the level of inflammation, and improve their exercise tolerance and their quality of life with good safety.
