Background:Damage of intestinal mucosal barrier is a key factor in the development and progress of acute pancreatitis(AP),and is closely related with the prognosis of the disease. Aims:To investigate the protective effect and possible mechanism of mucoprotective agent teprenone on intestinal mucosal barrier in rats with experimental AP. Methods:Forty-five adult male Sprague-Dawley rats were randomly divided into normal control group(n = 5),AP model group(n = 20)and teprenone treated group(n = 20). AP model was established by subcutaneous injection of cerulein at abdominal wall. Rats in treated group were intervened with teprenone intragastrically before and after model establishment. ELISA was used for measurement of serum interleukin-1(IL-1),IL-6,tumor necrosis factor-α(TNF-α)and amylase;histopathological and ultrastructural changes of small intestinal mucosa were observed by light microscope and transmission electron microscope;Western blotting was used to detect the expressions of tight junction protein occludin and ZO-1. Results:Serum levels of IL-1,IL-6,TNF-α and amylase in AP model group were significantly higher than those in normal control group(P < 0. 05),accompanied by necrosis and exfoliation of small intestinal villus,widening of intercellular tight junctions and downregulation of occludin and ZO-1 expression. While in teprenone treated group,serum levels of proinflammatory cytokines and amylase were significantly decreased as compared with AP model group(P < 0. 05),the villus of small intestine remained intact,and dense tight junctions were observed. Expressions of occludin and ZO-1 in teprenone treated group were upregulated. Conclusions:Teprenone may protect against intestinal mucosal barrier injury in AP model rats by upregulating tight junction protein expression.

BACKGROUND: The standardized treatment for patients who require total hip replacement is the implantation of an intramedullary diaphyseal anchored hip prosthesis. A bone-sparing non-stemmed hip prosthesis (NSHP) can be used as an alternative device for young patients. The NSHP relies on proximal femoral metaphyseal and neck fixation. The theoretic advantage of leaving diaphyseal bone intact is easier conversion to a stemmed prosthesis. On the other hand,clinical investigations published reported THR had high loosening rate of the prosthesis, which greatly limits its long-term clinical results; the aim of NSHP is to give the femoral prothesis a kind of biological fixation to decrease the loosening rate of the prosthesis. This retrospective study evaluated the medium- and short-term results after total joint replacement using NSHP.OBJECTIVE: To evaluate the outcome of NSHP for the treatment of young patients with hip disorders.DESIGN: Case analysis.SETTING: Department of Orthopaedics, the First Affiliated Hospital of Guangxi Medical University.PARTICIPANTS: Fifteen patients (17 hips) with hip disorders, who were treated at the Department of Orthopaedics,First Affiliated Hospital of Guangxi Medical University between 2001 and 2005, were retrieved. The involved patients included 8 males and 7 females. They were aged (37.8±9.8) years ranging from 21 to 49 years when they underwent operation. Indications for implantation included avascular necrosis (7 hips), posttraumatic osteoarthritis(4 hips), primary osteoarthritis(3 hips), osteoarthritis secondary to dysplasia(3 hips). Informed consents were obtained from all the patients before operation. The neotype of non-stemmed hip prosthesis (NSHP) was made of Co-Cr-Mo casting alloy with good biocompatibility by Shanghai Fusheng Medical Equipment Co., Ltd (Guoyao guanxie (shi) No. 2002-3040397; Guoshi Yaojianxie(zhun) No. 2005-3460799).METHODS: Fifteen patients (17 hips) with hip diseases subjected to the replacement of total hip with NSHP. Patients were followed-up once every other 6 months in the postoperative first year, then once every year, 5 years in total. The follow-up visit included functional evaluation and X-ray evaluation. ① Functional evaluation: Evaluative criteria of Harris joint function scale were adopted: full marks (point) =100, ≥ 80 excellent, ≥ 60 good, 40 fair and ＜ 40 poor; The following clinical data were documented: relief of pain, ability to lie on the operated side, additional procedures, use of pain medication, postoperative hip dislocations and so on. Pain was evaluated by using visual analogue scale (VAS),which ranged from 0 (no pain) to 10 (worst possible pain). ② X-ray evaluation: A standardized radiographic assessment was performed using an anteroposterior view of the pelvis. The following radiological data were recorded: preoperative grade of osteoarthritis as classified according to the method from Busse et al, preoperative grade of femoral head necrosis as classified according to the method from Ficat et al, inclination angle of the operated and the untreated side,radiolucencies according to the method of Buergi et al, heterotopic ossifications, as classified according to the method of Brooker et al. Postoperative adverse events and complications were observed and revision operation was needed if necessary.MAIN OUTCOME MEASURES: Correlative conditions of patients who were followed up for 5 years: ① Inserting angle of prothesis and the collodiaphyseal angle in the opposite side. ②Radiolucency and heterotopic ossification classification.③preoperative osteoarthritis classification, preoperative avascular necrosis of femoral head classification. ④ Revision operation, adverse events and complications. ⑤ Postoperative functional evaluation: Relief of pain (Harris joint function score), ability to lie on the operated side, additional procedures, use of pain medication, postoperative hip dislocations and VAS results.RESULTS: Fifteen patients were involved. One patient was lost after 3-month treatment and the other patients were followed up for 5 years. ① Postoperative functional evaluation results of patients. In the postoperative 5-year follow-up visit, hip joints of 13 patients (15 hips) were still in situ, pain lessened or disappeared in 11 patients (84.6% ,11/13),12 patients(92.3%, 12/13) would undergo the procedure again, 10 patients (76.9%, 10/13) were able to lie on the operated side; The average of Harris hip score was (72±19.6). The average Harris hip score did not vary significantly between the different diagnosis groups (P ＞ 0.05). Postoperative VAS was 2.6±2.2 on average. There was no significant difference in the hip joint pain among different diagnosis groups (P ＞ 0.05); Nine patients required no pain medication (69.2%,9/13).Two patients (15.4% ,2/13) occasionally took nonsteroidal anti-inflammatory drugs and two patients (15.4% ,2/13) took nonsteroidal anti-inflammatory drugs on a regular basis. ② X-ray evaluation results of patients: Preoperative osteoarthristis classification: One hip had grade 1 joint degeneration, 3 hips had grade 2 joint degeneration and 6 hips had grade 3 degeneration. Preoperative avascular necrosis of femoral head classification: Out of 7 patients with avascularnecrosis of femoral head, 4 patients had stage 3 femoral head necrosis, and 3 patients had stage 4 femoral head necrosis. In the postoperative 5-year follow up, 1 patient had radiolucency. Because the range of radiolucency was very small, progression was not quick and clinical symptoms were not severe, so revision operation was not conducted;In the postoperative 6th month, the inclination angle averaged (135.2±6.8)° on the untreated side and (132.2±6.5)° on the treat side. One patient with congenital hip dysplasia and a previous varus derotational osteotomy had a postoperative inclination angle below 120°. Patients with postoperative inclination angles between 125° and 140° had significantly less hip pain than the rest of the series. Heterotopic ossifications classification: Three patients had postoperative heterotopic ossifications, one hip had grade 1 heterotopic ossification, 1 hip had grade 2 heterotopic ossification, and 1 hip had grade 3 heterotopic ossification.③ Revision operation: one patient (5.9%,1/17)required a revision total hip arthroplasty due to pain. Good bone stock of the proximal femur was found in the patient which allowed implantation of a conventional medullary anchored prosthesis. This revision surgery and postoperative rehabilitation were uncomplicated.④ Adverse events and complications: Hip dislocation occurred postoperatively in one patient (5.9%,1/17). Other complications included trochanter bursitis (n=1), fistula (n =1), and seroma (n =1).CONCLUSION: ① NSHP provides biological fixation for femoral prothesis by bone proliferation through the windows with connective tissues surrounding the prothesis and has the characteristics of low stress and deformation, high intensity and rigidity, and anti-loosening, thus, may prolong its live lime. ②Revision surgeries are facilitated by the good bone stock remaining in the proximal femur. ③ The short- and medium-term therapeutic effects of total hip arthroplasty are satisfying in young patients.

Objective To investigate the possible effects and underlying mechanisms of desferroxamine (DFO) preconditioning against hypoxia in neurons. Methods Cortical neurons were cultured in DFO under ischemia condition of oxygen-glucose deprivation (OGD). Cell viability was determined by cell counting kit-8 (CCK-8) method; apoptotic cell ratio was examined with Hoechst 33342 staining; the morphological change was observed. Middle cerebral artery was occluded with or without DFO administration to establish the cerebral ischemia rat model. Infarct sizes were examined by TIC staining, and the neurological severity score was evaluated. Meanwhile immunofluorescent staining was employed to detect the protein synthesis of hypoxia inducible factor-1 (HIF-1) and erythropoietin (EPO), RT-PCR was performed to detect the mRNA expression of HIF-1 and EPO as well Results Neuronal viability kept in 49% (OGD group was 25%, t =8. 544, P<0. 05), the rate of apoptosis was 38% (OGD group was 30%, t = 4. 409, P <0.05 ) after administration of DFO (post-DFO) , the morphology of neurons improved. In the model of focal cerebral ischenfia of 30 mg/kg group, neurological severity score was reduced, the percentage of brain infarct decreased 8.5% (t=4.649, P<0.05) 3 days post-DFO(vs control). In the 100 mg/kg group, neurological severity score was 7.44 ±0.39 (t=2.903, P<0.05 ) ,5.60±0.47 (t=10.143, P < 0.01 ) ,6.97 ±0.73 (t=3.142, P<0.05 ), the percentage of brain infarct decreased 12. 0% (t=5.056, P<0.05), 32.3% (t =10.993, P<0.01), 10.6% (t =4.385, P<0.05)2,3 and7 days post-DFO(vs control), respectively. Immunofluorescent staining found synthesis of HIF-1α and EPO in cultured cortex neurons after DFO pretreated; HIF-1α and EPO were upregulated in the neurons of rat brain after DFO pretreated. The mRNA of HIF-1α and EPO upregulated in vivo and in vitro. Conclusion DFO preconditioning can protect the brain against ischemic damage, which is related to the protective effect on neurons. The mechanism of DFO preconditioning may be involved in the expression of HIF-1α and EPO in vivo and in vitro.
