International Journal of Laboratory Medicine 2009;30(7):653-654
Objective To compare the resistance of metallo-β-lactamase -producting Pseudomonas aeruginosa between burn ward and other wards, so as to provide basis for reasonable use of antimicrobial agents. Methods BD Phoenix-100 bacteria identification and drug sensitivity analyzer was used to detect Pseudomonas aeruginosa and its susceptibility, and disc synergy method was used for the screening of metallo-v-lactamase -producting Pseudomonas aeruginosa. Results Of 68 strains of Pseudomonas aeruginosa, 9 strains (13.2%) were metallo-β-lactamase (MBL) positive. Among the 9metallo-β-lactamase positive strains, 7 strains were from the burn ward and 2 strains from other wards. The resistance rate of the MBL-producing strains to ceftazidime, cefotaxime, imipenem, ciprofloxacin, amikacin, gentamicin, piperacillin and aztreonam was respectively 100.0%, 100. 0%, 88.9%, 66.7%, 88.9%, 100,0%, 100.0%, and 88.9%, obviously higher than that of non-MBL-pro-ducing Pseudomonas aeruginosa. Conclusion The rate of MBL-producing Pseudomonas aeruginosa is obviously higher in burn ward than that in other wards. The resistance of MBL-producing Pseudomonas aeruginosa is high against commonly used antimicrobial agents. Clinical use of antibiotics should he based on the antimicrobial susceptibility test results.
2.Empathy – The Essentials in Counselling People with HIV
The Singapore Family Physician 2013;39(1 (Supplement)):8-9
The landscape of HIV has changed from an incurable disease to be more like a chronic disease as the result of advances in medications; the lifespan of People Living with HIV (PLHIV) has also lengthened, HIV defining diseases are delayed, and many of the complications of HIV prevented with adherence to medications. The stigma and discrimination of HIV remain however. PLHIV need to cope with emotional issues of guilt, shame, and self-blame; social issues of rejection, termination of employment, fear and bad social experiences. The paradigm shift from negative regard of PLHIV to that of empathy, which is a deliberate and conscious attitude to relate to PLHIV as fellow travellers in life, to be able to feel with them rather than against them, has therapeutic effects. Empathy has its processes of active listening, responding with appropriately chosen words to describe feelings of the patients, and reflecting the desire to understand more about the patient’s emotions and social turmoil. The benefit of empathy in counseling are the ability to connect with the patient, to build trust from the patient being counseled, and a more objective perspective of being able to see the patient from his/her perspective rather than from the therapist’s perspective. More importantly empathy is a positive response to emotional and social issues experienced by the patient compared to platitudes like “You will be alright; or “don’t worry”, which negate and minimise the opportunity to have a catharsis.

Objective To investigate the possibility of transmission of severe acute respiratory syndrome (SARS) related coronavirus by transfusion of unreliable blood and relevant product. Methods ELISA technique was used to detect the antibodies of SARS associated coronavirus in the plasma from 158 volunteer blood donors, who were medical workers, before the SARS epidemic. The subjects with positive result were place under surveillance. Results There were two positive samples in 158 tested samples. The subjects with positive test result did not have the history of SARS infection. Conclusion There was no epidemic of SARS in the hospital. The transmission pathway of SARS was unknown. It seems that the risk of transmitting SARS by unreliable blood product transfusion is just a theoretical hypothesis. With further investigation of SARS, its transmission pathway will be hopefully made known.

Objective To explore the curative effect of stomatitis spray combined with 3M liquid dressing on degree II red buttocks in infants and summarize key points of nursing care. Methods From April 2012 to June 2016, 64 infants with degree II red buttocks were treated in our department. According to the admission time, the infants were divided into control and experiment groups in equal number. The control group was treated with zinc oxide ointment, and the experiment group with stomatitis spray combined with 3M liquid dressing. The curative effect, total effective rate, and wound healing time were compared after treatment between the groups. Results The curative effect and total effective rate of red buttocks in the experiment group were significantly better than those of the control group (P<0.05). Moreover, the wound healing time in the experiment group was obviously shorter than that of the control (P<0.05). Conclusions Compared to zinc oxide ointment, the stomatitis spray combined with and 3M liquid dressing is more effective in the treatment of severe red buttocks of the infants. Moreover, the latter is advantageous in wound healing time, compliance, treatment, and curative effect, which indicates its potential application in clinic.

Objective: To investigate the differences of biochemical markers between the patients with pulmonary hypertension related to left heart disease (PH-LHD) and LHD; to explore the sensitive bio markers which may predict PH in LHD patients. Methods: A total of 355 LHD patients admitted to our hospital from 2014-01 to 2015-05 were enrolled. According to 2009 ESC/ERS guidelines, PH was deifned by pulmonary artery systolic pressure (PASP)>50 mmHg and patients were divided into 2 groups: LHD group,n=224 and PH-LHD group,n=131. The basic information with blood levels of biomarkers was recorded and their accuracy for predicting PH was analyzed. Results: The pathogenesis of LHD included 184 (51.83%) patients of coronary heart disease, 90 (25.35%) of dilated cardiomyopathy and 81 (22.81%) of cardiac valve heart disease. Compared with LHD group, PH-LHD group had increased ratio of NYHA III and IV degree (89.31% vs 45.54%), decreased LVEF [42.0 (33.0, 59.0) % vs 60.0 (42.0, 65.0) %], all P<0.001; PH-LHD group presented elevated blood levels of BNP, bilirubin, red cell distribution width (RDW), uric acid and cystatin C, while reduced lipoprotein (HDL), allP<0.001. PASP was positively related to biomarkers as BNP, bilirubin, RDW, uric acid and cystatin C, while negatively related to HDL. With the combination of BNP, direct bilirubin and RDW, the predictive value for PH-LHD under ROC curve was 0.828 with the sensitivity at 0.813, speciifcity at 0.708. Conclusion: Blood levels of biochemical markers were statistically different between the patients of PH-LHD and LHD; the combination of BNP, direct bilirubin and RDW showed the higher accuracy for predicting PH occurrence in LHD patients.

Objective To study the apoptosis mechanism of K562 cell lines induced by mangiferin. Methods The mRNA expression levels of apoptosis-related genes including bcl-2, bax, survivin of K562 cells treated by mangiferin (25—200 ?mol/L) for 24, 48, 72, and 96 h were determined by RT-PCR; the BCR/ABL protein P210 level was detected by Western blotting. Results Mangiferin up-regulated bax gene of K562 cells significantly and down-regulated bcl-2 gene slightly, resulting in an enhancement of the ratio of bax/bcl-2. Mangiferin down-regulated the expression levels of P210 in K562 cells in a time-and concentration-dependent manner and so is the expression level of survivin mRNA in K562 cells. ConclusionThe mechanism of mangiferin-induced apoptosis in K562 leukemic cells might be involved in up-regulating the gene expression of bax and down-regulating the mRNA expression of BCR/ABL protein P210, bcl-2, and survivin.

4-fold elevation in renal cortex in plasma aldosterone as compared to those of the SHAM rats. The above pathologies were markedly improved in bi-ectomised rats with significantly lower aldosterone level. Being constantly infused exogenous aldosterone, bi-ectomized rats manifested greater proteinuria, hypertension, glomerulosclerosis and increased level of TGF-?1 compared to bi-ectomised rats. Indeed, these features were similar in exogenous aldosterone rats and 5/6 nephrectomized rats. Furthermore, the expression of mineralocorticoid receptor (MR) mRNA was remarkablely enhanced in SNX group and was decreased in ADX group. However, the mRNA expression of 11 ?-hydroxysteroid dehydrogenase II (11?-HSD2) in each group was opposite to that of MRmRNA. Ccr and kidney/body weight showed no differences among four experimental groups. Conclusion Aldosterone contributes to the progression of ablative nephropathy in the rat through mechanisms other than systolic blood pressure.
