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.

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.

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

To explore the mechanism of the absorption enhancement of Angelica dahurica extract (Ade), the absorption mechanism of baicalin in the Scutcllaria water extraction as well as the effect of Angelica dahurica extract on absorption of baicalin were investigated. In order to determine the main absorption site, everted intestinal sac model was used to study the effect of Angelica dahurica extract on the absorption of baicalin at duodenum, jejunum, ileum and colon. In situ single pass intestinal perfusion model was performed to study the absorption of various concentrations of baicalin and the effect of Angelica dahurica extract on the absorption of baicalin at the main absorption site. To authenticate the consequence of perfusion by getting the blood from the hepatic portal vein and determine the concentration of the baicalin in the blood. The result showed that baicalin could be absorbed at all of the four intestinal segments with increasing absorption amount per unit as follows: ileum > colon > jejunum > duodenum. The absorption ofbaicalin in the duodenum significantly increased with Angelica dahurica extract, thus, duodenum was chosen to be the studying site. Apparent permeability values (Papp) and absorption rate constant (Ka) of baicalin in the duodenum increased gradually with higher concentrations. When the concentration of baicalin rises to a certain degree, the absorption increase had a saturable process, the absorption of baicalin may be an active transportation. Baicalin may be not a substrate of P-gp as verapamil which had not significantly affected the Papp and Ka of baicalin. The absorption of baicalin in the duodenum significantly increased (P < 0.01) in the two models with Angelica dahurica extract and the concentration of baicalin in the blood from the hepatic portal vein showed that the Angelica dahurica extract can increase the absorption of baicalin.

OBJECTIVETo study the clinicopathologic features of microscopic polyangitis (MPA), and to compare the differences in anti-neutrophil cytoplasmic autoantibody (ANCA)-positive and ANCA-negative patients, as well as in ANCA-positive cases with or without glomerular immunoglobulin deposition.

METHODSThirty-four biopsy-proven cases of MPA were retrieved from the archival files of the Department during the past 7 years. The clinicopathologic characteristics between ANCA-positive and negative patients, as well as between ANCA-positive cases with and without glomerular immunoglobulin deposition, were compared.

RESULTSAmongst the 34 MPA patients studied, about one-fifth to one-half were accompanied by various extrarenal symptoms. Serum ANCA was positive in 26 patients (76.5%). A slight to moderate increase in urinary protein was demonstrated in 31 patients, while 3 patients had nephrotic syndrome. Elevated serum creatinine was detected in 32 cases. Renal biopsy revealed crescentic glomerulonephritis in 24 cases, focal segmental glomerulonephritis in 8 cases, vascular fibrinoid necrosis with inflammation in 7 cases, intimal thickening of arterioles in 24 cases, interstitial inflammatory cells, including neutrophil infiltration (21 cases), in 29 cases. Crescentic formation was more common in the ANCA-positive group than in the ANCA-negative group (P < 0.05). Amongst the 26 ANCA-positive cases, 10 had glomerular immunoglobulin deposits (including 1 case with IgA nephropathy). In general, these cases had a greater degree of proteinuria than those without glomerular immunoglobulin deposits (P < 0.05).

CONCLUSIONSThe diagnosis of MPA relies on histologic examination of renal biopsy and clinicopathologic correlation. Serum ANCA seems important for glomerular crescent formation. Glomerular immunoglobulin deposition may also play a significant role in the exacerbation of proteinuria.
