Objective To investigate whether efflux mechanism is involved in azole resistant Candida albicans strains isolated in China. Methods We compared rhodamine 6G uptake and glucose induced efflux between azole sensitive and azole resistant strains to elucidate resistance to azole due to efflux pump, then measured mRNA level of efflux gene cdr1 and cdr2 by reverse transcriptase polymerase chain reaction (RT PCR). Results Rhodamine 6G moved from extra into the intracellular compartment in both azole resistant and azole sensitive strains quickly when in glucose free incubation condition. However, efflux of rhodanmine 6G was enhanced significantly in azole resistant strains and decreased in azole sensitive strains while adding glucose in the media. The mRNA level of efflux gene cdr1 and cdr2 was higher in clinical azole resistant strains and fluconazole induced resistant strains than strains reverted from resistance to sensitivity. However, all such strains had higher efflux gene expression than azole sensitive strains. Conclusions Efflux mechanism is associated with the resistance to azole in Candida albicans strains isolated in China. Fluconazole can induce efflux pumps expression leading to resistance to azole but the resistance to azoles can be reversed after withdrawing fluconazole.

Objective To investigate mRNA expression levels of cathepsin B,cathepsin L and uPA in non-Hodgkin lymphoma (NHL) samples,and analyze the relationship between three genes and clinicopathological factors.Methods Real-time fluorescence quantitative RT-PCR was used to quantify the relative expression levels of cathepsin B,cathepsin L and uPA mRNA in 39 NHL patients without chemotherapy or radiotherapy and 15 patients with lymph node reactive hyperplasia.Relationship between their expression and clinico-pathological factors was analyzed.Results mRNA expression levels of cathepsin B,cathepsin L and uPA in NHL group were significantly higher than those in the control group (0.403 vs 0.128,0.209 vs 0.057,0.459 vs 0.031,all P ＜ 0.05).The mRNA expression levels of cathepsin B,cathepsin L and uPA were correlated with each other in NHL.The mRNA expression levels of cathepsin B,cathepsin L and uPA in advanced staged NHL were markedly higher than those in early staged NHL (0.453 vs 0.341,0.204 vs 0.085,0.372 vs 0.196,all P ＜ 0.05).mRNA levels of cathepsin B,cathepsin L and uPA were higher in NHL patients sensitive to chemotherapy than in those resistant to chemotherapy(0.401 vs 0.556,0.085 vs 0.205,0.316 vs 0.499,all P ＜ 0.05).Conclusions The high expression of cathepsin B,cathepsin L and uPA could be detected in NHL,and their expression has a close relationship with the biological behavior characters of NHL.The dynamic examination of cathepsin B,cathepsin L and uPA may be used as clinical auxiliary diagnosis and prognosis of NHL.

MicroRNA is a type of endogenous noncoding small molecular RNA with a length of 19-25 nucleotides. MicroRNAs are involved in almost all key biological processes, such as cell proliferation, differentiation, apoptosis, and hematopoiesis, via repres-sion of target gene expression. Acute lymphoblastic leukemia (ALL) is the most common type of pediatric cancer. It is a heterogeneous disease with different clinical signs, morphology, immunophenotype, and cytogenetics. Currently, several microRNAs have implicated aberrant expression in ALL and play an important role in cancer initiation and development. MicroRNA expression pattern is associated with clinical feature, prognosis, and treatment. Therefore, microRNAs could act as a novel marker to help scientists learn about the pathogenesis of ALL and to provide more effective treatment options.

Heart disease is the major disease that threaten human health. ECG is an important tool for the diagnosis of cardiac disease. As traditional ECG measurement devices have many disadvantages, a non-contact ECG measurement system was designed. With the non-contact electrode based on capacitive coupling, the signals were collected and then they were amplified and filtered. The conditioned analog signal was converted to digital data which was sent to the mobile terminal through bluetooth. Finally, the ECG data was analyzed to extract the key ECG parameters. The results showed that the precise ECG signals can be got with the non-contact electrode and the key ECG parameters can be acquired accurately.

Objective To explore the distribution and antimicrobial resistance of pathogens causing urinary tract infection(UTI)in patients with prostatic hyperplasia,and provide reference for clinical diagnosis and rational anti-microbial therapy.Methods Urine culture results of 171 patients with prostatic hyperplasia complicated with UTI from February 8,2012 to October 12,2013 were analyzed retrospectively.Results A total of 192 bacterial isolates were isolated from 171 patients,gram-negative bacteria accounted for 79.17%,37.50% of which were Escherichia coli (E.coli )strains,and 18.75% were Klebsiella pneumoniae (K .pneumoniae );gram-positive bacteria and Candida accounted for 18.23% and 2.60% respectively.Of E.coli and K .pneumoniae ,the proportion of extend-ed-spectrumβ-lactamase (ESBLs)strains were relatively higher,which was 72.77% and 63.89% respectively,re-sistant rates of ESBLs-producing E.coli to piperacillin.cefuroixme,ceftazidime,ceftriaxone,aztreonam,and levo-floxacin were all significantly higher than non-ESBLs strains,resistant rates of ESBLs-producing K .pneumoniae to piperacillin,cefoxitin,aztreonam,levofloxacin,and compound sulfamethoxazole were all significantly higher than non-ESBLs strains.Resistant rates of Pseudomonas aeruginosa to imipenem and meropenem were both 50.00%, susceptibility rates of Enterococcus to penicillins and aminoglycosides were both low,linezolid-and vancomycin-re-sistant strain was not found.Conclusion Organisms isolated from patients with UTI associated with prostatic hy-perplasia have high antimicrobial resistance,clinical therapy should be based on characteristics of bacterial distribu-tion and antimicrobial resistance.

Objective To explore the relationship between blood pressure changes and prognosis in patients with acute stroke by ambulatory blood pressure monitoring. Methods 79 patients with acute stroke were divided into two groups: cerebral infarction group (n=42) and cerebral hemorrhage group (n=37). Blood pressure of patients in both groups was monitored, and the score of handicap was evaluated respectively on 30d after onset. Results (1)Blood pressure was elevated in 87.3% of the patients with stroke at acute stage and then lowered spontaneously. Compared with that of the 1st day after onset, blood pressure lowered significantly from [SBP (155.9?21.7), DBP (96.6?20.8) mmHg] to [SBP (147.6?17.2), DBP (85.6?13.6) mmHg] (P

Application of a number of philosophical ideas is instructive in eliminating the opposition on the doctors'right to inform and the patients right to being informed,building a harmonious relations between doctors and patients and correctly understanding and carrying out the informed consent.

Objective To investigate the clinical effect of the treatment of acute radiation dermatitis caused by radiotherapy in nasopharyngeal carcinoma patients treated with hydrogen. Methods Selected from January 2014 to January 2016 for nasopharyngeal carcinoma in the first hospital of Ningbo radiotherapy lead to acute radiation dermatitis patients were studied, by drawing lots method were divided into treatment group and control group with 40 cases in each. The patients in the control group were given conventional treatment, iodine inunction, treatment group given routine treatment, hydrogen card grease rubbed. Comparison of two groups of treatment effect. Results After 10 days of treatment, the treatment group the score RISRAS significantly lower than the control group (P < 0.05). Conclusion Combination of hydrogen and conventional therapy in the treatment of acute radiation dermatitis induced by radiotherapy in nasopharyngeal carcinoma patients, can significantly shorten the treatment time.
