BACKGROUND: Posterior lumbar interbody fusion is the main repair method for senile degenerative lumbar spondylolisthesis. For elderly patients with osteoporosis, single screw rod system fixation regularly results in dislocation. The incidence of implant loosening is high, and therefore, effective internal fixation is not achieved. OBJECTIVE: This study will use the modified posterior lumbar interbody fusion procedure combined with bone cement augmentation for the treatment of senile degenerative lumbar spondylolisthesis so as to increase the stability of the vertebral body, make the fixator firm, and to maximize the recovery of postoperative motor function. METHODS: Totally 113 patients with senile degenerative lumbar spondylolisthesis, aged 65-70 years, irrespective of sex, will be recruited from the Department of Orthopedics of Affiliated Hospital of Qinghai University of China. The patients will be treated with modified posterior lumbar interbody fusion combined with bone cement augmentation. Follow-up will be performed at 3 and 12 months. The primary outcome measure is recovery of motor function as indicated by the postoperative Oswestry Disability Index score at 12 months. The secondary outcome measures are the change in the rate of excellent and good Oswestry Disability Index scores (comparing preoperative scores with the 4-month postoperative scores), Visual Analogue Scale scores, intervertebral space height, foraminal height, the preoperative and 4 and 14 months postoperative slip distance and slip angle, incidence of adverse reactions, success rate of vertebral fusion, and incidence of secondary slip 4 and 14 months postoperatively. This trial has been approved by the Medical Ethics Committee of Affiliated Hospital of Qinghai University of China(approval number:QHY023G).The study protocol will be proformed in accordance with the Declaration of Helsinki, formulated by the World Medical Association. Written informed consent will be obtained from all participants. This trial was designed in October 2017. The recruitment of subjects and data collection will begin in June 2018. The recruitment will be finished in December 2018. Outcome measures will be analyzed in January 2020. This trial will be completed in February 2020. The results of the trial will be reported in a scientific conference or disseminated in a peer-reviewed journal. This trial had been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR1800015335). Protocol version (1.0). DISCUSSION: This trial aims to observe the efficacy of modified posterior lumbar interbody fusion combined with bone cement augmentation in the treatment of senile degenerative lumbar spondylolisthesis and to validate whether the procedure is safe and reliable.

Objective To explore the effect and indication of splenectomy in liver transplantation.Methods From January 2001 to April 2006,260 patients underwent piggyback orthotopic liver transplantation(PBOLT),and 28 patients had undergone combined PBOLT and splenectomy(splenectomy group).These patients were compared to 56 randomly selected non-splenectomy patients from the same transplant period,meaningly two controls were se- lected for every non-spleneetomy case.Two groups were analyzed with respect to rate of infection and survival rate, as well as biopsy-proven acute allograft rejection within 30 days after transplantation.Results Rate of infection in the splenectomy group was higher than that in the non-splenectomy patients(85.7% vs 55.4%,P

OBJECTIVETo explore the therapeutic effect of interleukin-11 (IL-11) on high-dose methotrexate (HDMTX) induced mucositis in Wistar's rats, the proliferative effect on CEM leukemia cell line and the antitumor effect on HDMTX.

METHODSNinety-five 5-week old, 120 - 150 grams weight Wistar rats were randomly divided into five groups. Group A is normal control (n = 15), group B MTX control (n = 20), group C IL-11 pretreatment group before MTX injection (n = 20), group D (n = 20) the high dose IL-11 group (475 microg.kg(-1).d(-1)) after MTX injection, group E (n = 20) the low dose IL-11 group (150 microg.kg(-1).d(-1)) after MTX injection. All rats in group B approximately E were given 1 ml MTX intraperitoneally (100 mg/kg). Rats were killed at day 1, 3, 5, 7 after MTX injection. The mortality rates, changes of small intestine tissue morphology and ultra structure were observed. The proliferation of small intestine crypt cell was assayed by proliferating cell nuclear antigen (PCNA) immunohistochemical staining. MTT method was used to detect the proliferation of CEM cell line.

RESULTIL-11 treatment resulted in a significant increase of survival of HDMTX treated rats, increased of small intestinal villus length and villus/crypt ratio. IL-11 administration was associated with enhancement of small intestine mucosa recovery after HDMTX therapy. Group C showed a greater effect than group B (P < 0.01). IL-11 had no effect on CEM cell proliferation.

CONCLUSIONIL-11 has a significant mitigating effect on high-dose MTX induced intestinal mucositis in rat, and significantly increase the survival of the rats. IL-11 could be safely used in the HDMTX treatment of childhood acute lymphocyte leukemia.

AIMTo explore the changes of mRNA and protein expressions of heart-type fatty acid binding protein (H-FABP) in rat ischemic myocardium at different intervals ischemia.

METHODS60 SD male rats weighing 250-350 g, were randomly divided into one sham-operated group and five study groups (group A1, A2, A3, A4, A5, the left coronary artery of rats has been ligated for 1 h, 2 h, 4 h, 6 h, 12 h respectively). Myocardil samples from infarct zone, ischemic and non-ischemic zone, were obtained for histology examination, and the mRNA for H-FABP in ischemic myocardial tissue were determined by RT-PCR. Serum free fatty acid(FFA) was determined by colorimetric method.

RESULTSCompared to sham hearts, H-FABP mRNA expression were significantly decreased in ischemia zone of AMI rat hearts (P < 0.05), especially in rats underwent 4 h ischemia and 6 h ischemia (P < 0.01). Serum FFA were significantly increased in AMI rats relative to sham rats (P < 0.05).

CONCLUSIONSignificant down-regulated heart-type fatty acid binding protein after myocardial ischemia might play an important role in myocardial injury and energy metabolism disorder.

Objective To investigate the reasons of unacceptable results and corrective measures adopted in external quality assessment (EQA)for blood gas and acid-base analysis.Methods The reasons of unacceptable results and corrective measures for three EQA testing events of blood gas and acid-base analysis in 2016 were reported through EQA system based on web which was developed by National Central for Clinical Laboratories.The responses were divided into seven major groups,including EQA samples,errors in reporting results,methodology,equipments,techniques,EQA evaluations and unexplainable results after survey.Results The disqualified rates of EQA survey on blood gas and acid-base analysis were ranged from 0.5％ to 13.1％ and reporting rates of disqualification causes were ranged from 45.8％ to 69.0％ (except for the groups less than 20 laboratories).In the reasons for unacceptable results technological defects (35.9％ to 37.0％)were mainly associated with inappropriate specimen handling and/or storing,reagents and calibration problems.The defects of equipments (24.4％ to 27.9％) included mainly the malfunction and failure to adhere to scheduled instrument maintenance procedures.The errors in reporting results (12.2％ to 19.7％) were mostly transcription errors and reporting wrong codes.The unexplainable results after survey account for 8.7％ to 9.6％.The methodological defects (8.1％ to 11.8％) were largely attributed to inadequate training and quality control method.The defects of EQA evaluations (0.8％ to 3.3％)were all due to inappropriate grouping.The categorizations of the problems in the three EQA testing events were similar.The most corrective measures were appropriate,in which re-education and training for staff and improvement in instruments,reagents,internal quality control,calibration and process of reporting results were included.Conclusion The analysis and classification for reasons of unacceptable EQA results should be helpful for laboratories in identifying opportunities for improvement and adopting corrective measures in time.

OBJECTIVETo carry out epidemiological study on an outbreak caused by E. coli O157:H7 infection in Jiangsu province in 1999.

METHODSEpidemiological, microbiological and moleculebiological methods were used to find out the source, route of transmission and risk factors.

RESULTS95 severe O157:H7 infected patients with acute renal failure in 9 counties and districts of 2 municipalities were reported in Jiangsu province, 1999 while 83 of the patients died with a death rate of 87.37%. Most patients were seen in mid or late June. The ratio of male to female was 1 to 1.44 and 88.42% of the patients were over 50 years old. 38 patients occurred in 2000 with 34 deaths. Major factors contributing to the outbreak would include without drinking tap water, eating leftover food, poor sanitary status in kitchen, not washing hands before meal and after bowl movement. 2 strain of O157:H7 was isolated from severe patients and 3 from diarrhea cases. Carrier rate among animals was up to 9.62% and 99.41% of the strains carried toxic gene. Strains isolated from feces of patients and animals belonged to the same colonies.

CONCLUSIONThis outbreak was severe which caused by O157:H7 and was first seen in China, which was closely related to the high carrier rate of O157:H7 in animals and to the positive rate of high toxic gene of the strains. There were various routes of transmission and the main factors of infection would include poor personal health habits and poor sanitation of the household.
