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.
2.Clinical study of renal transplantation in the elderly patients
Chinese Journal of Organ Transplantation 1998;19(2):111-112
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.
4.Effects of the indoleamine 2,3- dioxygenase- initiated L- tryptophan metabolism in organ transplantation
International Journal of Surgery 2012;39(5):339-342
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.
5.Research progress in polymeric nanoparticle delivery systems for growth factor in tissue engineering
International Journal of Biomedical Engineering 2011;34(1):39-42
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.
6.Application of enhanced recovery after surgery in laparoscopy-assisted distal gastrectomy
Cancer Research and Clinic 2017;29(3):180-183
Objective To evaluate the feasibility and efficacy of enhanced recovery after surgery (ERAS) combined with laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer. Methods 60 patients with distal gastric cancer from April 2016 to September 2016 in Shanxi Cancer Hospital were enrolled. According to the admission time, the patients were numbered randomly by odd and even. 30 odd patients received conventional treatment (traditional group), and were even 30 incorporated into ERAS group. Record and comparison of two groups were conducted, including age, sex, weight, body mass index (BMI), 1-day preoperative serum albumin (ALB) level, operation time, anastomosis type, total intraoperative blood loss, postoperative TNM staging, bowel movement recovery time, postoperative hospital stay, total cost of hospitalization, complications, and serum ALB level after operation. Results The level of ALB in ERAS group was (36.16 ± 2.46) g/L at 4th day after operation, and (39.61±2.03) g/L at 7th day after operation, which were higher than those in traditional group [(34.38 ±2.31) g/L and (37.98 ±1.96) g/L, respectively], with stable changes and statistical difference (P= 0.006, P= 0.003). The recovery time of intestinal peristalsis in ERAS group was shorter than that in traditional group [(51.23±9.05) h vs. (58.97±9.61) h, P= 0.003], and the total hospitalization cost in ERAS group was less than that in traditional group [(7.23±0.34) × 104 yuan vs. (7.58± 0.37) × 104 yuan, P< 0.001]. There were no significant differences in age, sex, weight, BMI, 1-day preoperative serum ALB level, operative time, anastomosis type, total intraoperative blood loss, postoperative TNM staging, complication and the postoperative hospital stay between the two groups (all P > 0.05). Conclusion The combination of ERAS and laparoscopic-assisted distal gastrectomy is safe and effective compared with traditional ways, which can relieve the stress reaction, promote the recovery of gastrointestinal function, reduce the hospitalization cost, and accelerate the rehabilitation of patients.
