OBJECTIVETo investigate the effects of the quinoline derivative PQ1 combined with cisplatin on the proliferation and gap junction communication of prostate cancer PC3 cells.

METHODSWe cultured in vitro prostate cancer PC3 cells and divided them into DMSO blank control, cisplatin control, and cisplatin (10 mg/ml) plus PQ1 (1, 2, 5, 10, and 15 μmol/L) groups. We measured the proliferation of the prostate cancer PC3 cells, determined the expressions of the connexin 43 (Cx43) mRNA and protein by RT-PCR and Western blot, and compared the indexes among different groups.

RESULTSCisplatin combined with PQl at 1 - 10 μmol/L significantly inhibited the proliferation of the PC3 cells and the inhibition rate rose in a concentration- and time-dependent manner, from (48.72 ± 0.98)% vs (50.33 ± 0.62)% at 0 μmol/L to (77.38 ± 1.12)% vs (83.50 ± 1.05)% at 15 μmol/L at 24 and 48 hours (P < 0.05). Compared with the cisplatin control, cisplatin combined with PQ1 at 1, 2, 5, 10, and 15 μmol/L increased the expression of Cx43 mRNA from 0.379 ± 0.113 to 0.669 ± 0.031, 0.831 ± 0. 127, 0.769 ± 0.100, 0.532 ± 0.086, and 0.475 ± 0.134, respectively (P < 0.05), and cisplatin combined with PQ1 at 1, 2, 5, and 10 μmol/L elevated that of Cx43 protein from 0.138 ± 0.146 to 0.263 ± 0.111, 0.306 ± 0.152, 0.415 ± 0.280, and 0.643 ± 0.310, respectively (P < 0.05).

CONCLUSIONThe quinoline derivative PQ1 can promote the gap junction communication of prostate cancer PC3 cells and enhance the killing effect of cisplatin on PC3 cells by upregulating the expressions of Cx43 mRNA and protein.

Abstract: Objective　To analyze the distribution and drug resistance evolution characteristics of pathogenic bacteria of bloodstream infection in nine tertiary hospitals in Yunnan Province from 2017 to 2021, so as to provide reliable basis for rational selection of antibiotics in clinic. Methods Using the drug sensitive paper method or instrument method, the bacteria identification and drug sensitivity test were carried out in nine tertiary hospitals in different regions according to the unified technical scheme. The results were judged according to the Clinical and Laboratory Standards Institute (CLSI) breakpoint standard in 2021, and use WHONET5.6 for data statistical analysis. Results A total of 12 003 strains of pathogenic bacteria were isolated from bloodstream infection samples in the past five years, including 7 442 strains of Gram-negative bacteria (62.0%) and 4562 strains of Gram-positive bacteria (38.0%), with an increasing trend in the number of isolated strains; of these, 163 strains (1.4%) were isolated from outpatients and 11 840 strains (98.6%) were isolated from inpatients. The top three gram-negative bacteria were Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, of which 309 strains (4.2%) were carbapenem-resistant Klebsiella pneumoniae (CR-KPN), 29 strains (0.4%) carbapenem-resistant Escherichia coli and 19 strains (0.3%) carbapenem-resistant Enterobacter cloacae, and the number of CR-KPN was on the rise year by year. The top three Gram-positive bacteria were coagulase-negative staphylococci, Staphylococcus aureus and Enterococcus faecium, of which methicillin-resistant Staphylococcus aureus (MRSA) was detected for 213 strains, accounting for 27.7%, and decreased from 40.0% in 2017 to 23.4% in 2021, showing a downward trend year by year. No vancomycin-resistant staphylococci and enterococci were found. Conclusions The detection and composition of bloodstream infection pathogenic bacteria in multicenter have not changed much in the past five years, but each hospital has its own characteristics. The number of carbapenem resistant Enterobacteriaceae increased year by year, which should be paid more attention.

To systematically evaluate the efficacy and safety of tripterygium glycosides (TG) combined with ACEI/ARB preparation in treating diabetic nephropathy stage IV. The computer retrievals were made in Cochrane Libarary, PubMed, Embase, SCI, Sinnomed, CNKI, Chinainfo and VIP, and hand retrievals were conducted for meeting and academic papers (updated to December 30, 2014), in order to collect randomized controlled trials and quasi-randomized control trials for TG combined with ACEI/ARB preparation in treating diabetic nephropathy stage IV and set the literature inclusion and elimination standards. Eligible literatures were included and evaluated according to standards in Cochrane Handbook. RevMan 5.3 and Stata 12.0 were used for a Meta-analysis. A total of 13 randomized controlled trials and quasi-randomized control trials involving 1119 patients with diabetic nephropathy were included. The Meta analysis result showed that compared with the control group, the combination group showed better effects in reducing the 24-hour urinary protein [MD = -0.84, 95% CI (-1.02, -0.66)], raising albumin [SMD = 0.98, 95% CI (0.81, 1.16)], the total efficiency [OR = 4.23, 95% CI (2.77, 6.46)] and the significant efficiency [OR = 5.35, 95% CI (2.70, 10.60)], with no statistical difference in Serum Creatinine between Both groups [MD = -0.82, 95% CI (-4.30, 2.66), P = 0.64]. However, the risk of adverse reactions increased by 7% [RD = 0.07, 95% CI (0.03, 0.12)]. The Egger's test showed no publication bias. Tripterygium Glycosides combined with ACEI/ARB in treating diabetic nephropathy stage IV is supper than the single administration of ACEI/ARB, with a good prospect in clinical application. Nevertheless, due to the small-size and low-quality samples in this study, more high-quality and large sample-size randomized controlled trials shall be conducted to verify the findings.

Fosfomycin (FOM) is an antibiotic with a small relative molecular weight (138.1) and a long half-life, and has a unique chemical structure and antibacterial mechanisms. It exerts a bactericidal activity by inhibiting the early synthesis of bacterial cell walls. It is also a broad-spectrum antibiotic with a good drug tolerance and compliance and a low pressure to bacterial resistance, but no cross-resistance with other antibiotics. Recent studies show the effectiveness of FOM in the treatment of acute uncomplicated urinary tract infections and urogenital tract infections as well, such as prostatitis and epididymitis. This review focuses on the clinical application of FOM in the treatment of infectious diseases of the urogenital tract.

Objective To analyze the distribution of main pathogens,antimicrobial susceptibility,and clinical characteristics of osteoarticular infection,and provide evidence for clinical treatment.Methods A retrospective sur-vey was conducted on clinical data and pathogenic results of hospitalized patients with osteoarticular infection diag-nosed by etiology and pathology in Peking University First Hospital from 2009 to 2016,surveyed data were analyzed statistically.Results A total of 99 cases of bacterial osteoarticular infection were enrolled,100 strains of pathogenic bacteria were isolated,gram-positive bacteria accounted for 67.00%,49.00% of which were Staphylococcus spp., Enterobacteriaceae bacteria accounted for 67.74% of 31 strains of gram-negative bacteria.Isolation rate of methicil-lin-resistant Staphylococcus aureus (MRSA)was 16.13%,resistance rates of Staphylococcus spp.to fluoroquino-lones and rifampicin were both lower than 30%.Complication with other site infection (urinary tract infection,in-testinal infection,bloodstream infection)was an independent risk factor for gram-negative bacterial steoarticular in-fection (P＝0.027,OR＝10.536,95% CI:1.300－85.417).Conclusion Staphylococcus spp.is still the main pathogen causing osteoarticular infection,proportion of MRSA is low.Patients with urinary tract infection and in-testinal infection as well as long duration of implant should be considered the possibility of gram-negative bacterial infection when they develop steoarticular infection.

Abstract: Objective　To analyze the distribution characteristics of the main pathogens of HIV/AIDS patients with wound infections and provide basis for clinical diagnosis and treatment. Methods　The clinical data of 294 patients with positive secretions or pus specimens from 2016 to 2020 were analyzed retrospectively. Results　A total of 357 strains of pathogenic bacteria were isolated from 294 cases, of which 123 strains of Gram-negative bacilli (G-b), accounting for 34.5%, were mainly Escherichia coli (15.4%), Klebsiella pneumoniae (3.9%), and Pseudomonas aeruginosa (3.6%); Gram-positive bacilli (G+b) 14 strains, accounting for 3.9%; 108 Gram-positive cocci (G+c), accounting for 30.3%, of which 44 strains were coagulase-positive Staphylococcus aureus (12.3%), Coagulase-negative staphylococci were mainly Staphylococcus epidermidis (4.2%) and Staphylococcus hemolyticus (2.8%); 37 strains of fungi, accounting for 10.4%, were mainly Candida albicans (5.9%); 75 strains of Mycobacterium, accounting for 21.0%, including 41 strains of Mycobacterium tuberculosis (11.5%) and 34 strains of non-tuberculosis mycobacteria (9.5%). 52 of the 294 HIV/AIDS patients had mixed infections, accounting for 17.7%. There was significant difference in the distribution of G+c, G-b, mycobacteria and mixed infection among different specimen sources (P<0.05), and there was significant difference in the distribution of mycobacteria among different CD4+T lymphocyte counts (P<0.05). There was significant difference in the level of CD4+T lymphocytes between patients of different ages (P<0.05), and there was significant difference in the level of CD4+T lymphocytes from postoperative incision and other parts (P<0.05). Conclusions　Patients with HIV/AIDS are prone to combined wound infections with various pathogenic bacteria. We should strengthen the research on wound infection in HIV/AIDS patients, and timely send patients with a low number of CD4+T lymphocytes for secretion or pus culture, so as to carry out targeted treatment and improve the prognosis of patients.
