OBJECTIVE:To study the enterococcal distribution in clinical samples and their drug resistance to commonly use antibiotic and provide the guidance for rational administration.METHODS : Adopting paper diffusion method to observe the drug resistance of enterococci isolated from clinical samples in our hospital and analyzing their distribution in the samples.RESULTS :Enterococcus faecalis accounts for 44.1% in 227 strains and Enterococcus faecium accounts for 37.9%,the other kinds of enterococci were rare.There was no statistical difference between drug resistance of Enterococcus faecium and that of enterococcus faecalis. Vancomycin was the most potent antimicrobial.Penicillin,ampicillin,and nitrofurantion showed good antibacterial activity against enterococcus faecalis. Enterococcus faecium displayed high-level resistance against antibiotics in addition to glycopeptides.CONCLUSION:Doctor should pay attention to the drug resistance about clinically common pathogenic bacterium. Continual surveillance of resistance rate of enterococcus is important to direct the treatment of enterococcus infections.

Tryptophan is the essential amino acid in the growth of cell.Indoleamine 2,3-dioxygenase is the rate-limiting enzyme in the catabolism of tryptophan along the kynurenine pathway.Indoleamine 2,3-dioxygenase enzyme mainly promotes tryptophan consumption of local micro-environment,causing tryptophan lack,thus inhibiting proliferation and activation of T cell.Tryptophan-derived catabolites suppress allogeneic T-cell proliferation (kynurenine,3-hydroxykynurenine,and 3-hydroxyanthranilate).Indoleamine 2,3-dioxygenase dendritic cells may interact with regulatory T cells forming an immunomodulatory network to promote immune tolerance induction.Though the immune regulation mechanism of the indoleamine 2,3-dioxygenase-initiated L-tryptophan in transplantation remains unclear,Numerous researches indicate that its role of tolerance induction in transplantation will be significant.

Effective loading and site-specific delivery of growth factors to regulate the cell growth on scaffold is one of the key issues of tissue engineering. Polymeric nanoparticle is one of the candidate carriers for carrying growth factors. This article attempts to introduce the biological characteristics of growth factors commonly used in tissue engineering, polymer materials for carrying the growth factors and the preparation of the nanoparticles and delivery systems. The advantages and disadvantages of different preparations are also discussed to facilitate the selection of the appropriate methods and materials. Relevant research progress and application potentials are discussed ss well.

OBJECTIVETo compare the differences in the clinical efficacy on neurogenic bladder after spinal cord injury (SCD between the matrix needling technique combined with rehabilitation training and rehabilitation training in the patients.

METHODSSixty patients of SCI neurogenic bladder were randomized into an observation group (29 cases) and a control group (31 cases). In the control group, the conventional rehabilitation therapy, the intermittent catheterization and bladder function training were adopted, once every day, for 4 weeks totally. In the observation group, on the basic treatment of the rehabilitation as the control group, the matrix needling technique and acupuncture at sanyin points were applied. The treatment of 8 days made one session, at the interval of 2 days, continuously for 3 sessions, meaning 4 weeks totally. The bladder function score, residual urine volume and bladder capacity were compared before and after treatment in the two groups.

RESULTSThe bladder function score was reduced after treatment as compared with that before treatment in either group (both P<0. 05). The score in the observation group was lower than that in the control group after treatment (P<0. 05). No matter which spinal segment was injured, the residual urine volume after treatment was reduced as compared with that before treatment and the bladder capacity was increased (P<0. 05). The residual urine volume in the observation group was less than that in the control group after treatment and the bladder capacity was more increased (P< 0. 05).

CONCLUSIONThe conventional rehabilitation program in combination with the matrix needling technique and acupuncture at sanyin points achieve the significant efficacy on SCI neurogenic bladder.

To explore the status of acupuncture and moxibustion for prevention and treatment of lung cancer in current years; literature regarding acupuncture and moxibustion for prevention and treatment of lung cancer between 2003 and 2013 from SCI journals was retrieved and analyzed. As a result, 20 papers were included, which were published in 17 journals including Journal of Clinical Oncology, Chest, Respirology and Lung Cancer, etc. Of them, 3 papers discussed the effects of acupuncture on progressing of lung cancer; 4 articles confirmed that acupuncture could reduce myelosuppression and digestive tract reactions induced by radiotherapy and chemotherapy; 6 papers showed that acupuncture could relieve pain or fatigue of lung cancer; 3 papers indicated that acupuncture could palliate dyspnea in lung cancer patients. It is concluded by domestic and overseas researches that acupuncture and moxibustion are effective and safe for symptoms of lung cancer, which is worthy of further study.

To investigate the outcome of renal transplantation in the elderly patients,the sur-vival rate,postoperative complications,rejection incidences and causes of death after renal trans-plantation in the elderly patients were compared to those of the contemporary younger patientsduring a follow-up of 5 years.No significant difference was found in the patients/graft survivaljection incidence was only 16%6 months after renal transplantation.Infection was the most com-mon complication and the main cause of death.The findings suggest that the elderly patients aresuitable for the renal transplantation as younger ones.

AIM　To synthesize derivatives of 2-[substituted phenyl)vinyl] indole and find compounds with biological activities by screening in vitro. METHODS　Twenty-one compounds of 2-[(substituted phenyl)vinyl] indole were synthesized by reduction, oxidation and Witting reaction. MS, 1HNMR and elemental analysis were used to determine the structures of the new compounds. RESULTS　These compounds are new ones. CONCLUSION　Six compounds (3,9,11,13,18 and 20) showed effects on some different receptors, such as alpha2, D2 and H1, and is worth further studying.

Anterior mandibular fracture, which includes symphyseal and parasymphyseal mandibular fractures, is one of the most common types of fracture in clinical work, and is usually associated with condyle fracture. This type of fracture predisposes the patients to facial widening, malocclusion, and ankylosis when not properly and timely treated because of the influence of its anatomic structure. This article reviews the characteristics, complication, diagnosis, and therapy of this type of fracture.

Objective:To discuss the management and maintenance of medical equipment in hospital, the department of biomedical and engineering should develop a reasonable management plan to meet the needs of using safety management of medical equipment based on the risk analysis.Methods: Make up a strategy based on the analysis of application risk according to the clinical function, physical risk, fault avoidable probability and the adverse events recorded, and conduct the preventative maintenance and safety performance inspection. Results: The focus of clinical engineering professionals change from passive acceptance to repair equipment to preventive equipment maintenance, and carry out safety performance inspection to reduce the risk caused by the failure of equipment which is harmful to the patients.Conclusion: The clinical engineering professionals need to pay attention to the application risk and improve the management strategy while they improve the technical level.
