Objective To set up the isolated perfused rat liver model. Methods Rat livers were harvested after the cannulation of the portal vein and bile duct. The reperfusion solution was Krebs-Henseleit solution containing bovine albumin serum and sodium taurocholate. The original CZ-1 isolated perfused rat liver system contained two subsystems: recirculating perfusion system and heat-exchange system. Then we modified the original CZ-1 system and omitted the heat-exchange system.The modified CZ-1 system consisted of a thermostatically regulated water bath,a peristaltic pump,a 4-neck round-bottom flask, a flow meter, an in-line manometer, a glass organ chamber, an iron support and a set of recirculating pipe line. Then the livers were connected via the portal vein to the modified CZ-1 system for 120 min. After 120 min reperfusion, bile production was evaluated. Routine HE staining and electron microscopic examination of hepatic tissues were also performed. Results The was not significantly different from that reported by references. Hepatic tissues in reperfusion group were also morphologically normal Conclusion The CZ-1 isolated perfused rat liver system was cost-effective and reliable to use. It was easy to run and is the ideal model for investigation of organ preservation solution.

The body is equipped with kinds of transporters which generally exist in liver,kidney,and intestine.Multidrug and toxin extrusion proteins(MATEs;SLC47A)are predominantly expressed in the brush-border membrane of proximal tubule epi-thelial cells in the kidney and the canalicular membrane of hepa-tocytes.Functionally,MATEs act as efflux transporters for or-ganic compounds.The article discusses type,structure,poly-morphism and function of MATE1and MATE2-K,and also dis-cusses the effect of single nucleotide polymorphisms (SNPs)in the SLC47A1 gene and SLC47A2 on the pharmacokinetics and pharmacodynamics of metformin and platinum-based chemothera-peutic agents.

Objective To observe the effect of early rehabilitation therapy on recovery from reoperation for recurrent lumbar disc herniation (RLDH).Methods Sixty-five cases who received surgery for RLDH between 2007 and 2009 were randomly divided into a rehabilitation group and control group.Both groups were treated with the same surgical approach and routine treatment.Early and comprehensive rehabilitation therapy was provided in the rehabilitation group during the perioperative period,including preoperative and postoperative muscle strength training,postoperative sitting and standing balance training,and acupuncture.The control group was instructed only in general exercise.Before the operation and 2 weeks and 3,6,12 and 24 months afterward,the surgical outcomes of all cases were assessed using the JOA score and the improvement rate in the JOA score.Any postoperative complications and intervertebral fusion were also observed.Results The average postoperative JOA scores of both groups were significantly higher than their preoperative scores.At all of the time points after the operation,the average JOA scores and all improvement rates in the rehabilitation group were significantly higher than those in the control group.Postoperative complications such as deep venous thrombosis,urinary retention and constipation were significantly less among the rehabilitation group than among the controls.All the intervertebral bone implants were well fused on time.Conclusion Early rehabilitation can significantly improve the effectiveness of RLDH reoperation and reduce the incidence of postoperative complications.It is recommended for clinical application.

BACKGROUND: Acute pancreatitis is a serious complication during pregnancy, however the incidence of hyperlipidemia induced by pancreatitis is lower. METHODS: We treated a pregnant woman with hypertriglyceridemia-associated acute gestational pancreatitis who simultaneously developed hypoxemic acute respiratory failure (ARF). RESULTS: The woman was successfully treated through noninvasive positive pressure ventilation (NPPV), emergent caesarean delivery, drainage of chylous ascites, and peritoneal lavage. CONCLUSION: The signs and symptoms of ARF were greatly improved in this patient after NPPV and conventional therapies. Early NPPV may be related to good prognosis of the disease.

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

Objective To evaluate the current status of treatment and prophylaxis of ischemic stroke associated with atrial fibrillation(AF),and to assess the opportunities for improvement. Methods Ninty-seven consecutive patients with acute ischemic stroke and AF were evaluated and compared with 173 acute ischemic stroke patients without AF.Medical records were reviewed using a pre-defined questionnaire developed from the guidelines.Functional outcome was measured according to modified Rankin scale. Results The patients with stroke and AF was older than the control group(years vs years,P

OBJECTIVETo explore the inhibitory effect of Fuzheng Yiliu Granule (FYG) on growth and apoptosis of H22 tumor cell, and expressions of p53 and Caspase-3 gene.

METHODSThe tumor inhibitory rate of FYG on H22 tumor cell line was observed in vivo, cell apoptosis rate and cell cycle were determined by flow cytometry (FCM), and expressions of wild type p53 and Capase-3 mRNA were determined by RT-PCR.

RESULTSFYG could inhibit the growth of H22 tumor cell at the dose of 12g/kg, 24g/kg, the maximal inhibitory rate up to 51.24% (P < 0.01). By FCM, it was shown that FYG could significantly enhance apoptosis rate of cell line H22, with the peak reached 15.84% (P < 0.01), and cause the tumor cell cycle being blocked at G0/G1 phase, with decrease of cells in S phase. RT-PCR illustrated that FYG could significantly up-regulate the level of p53 and Caspase-3 mRNA expression.

CONCLUSIONFYG can significantly inhibit the growth of tumor cell in mice, its anti-tumor mechanisms may relate to the cell apoptosis induction, cell cycle regulation and wild type p53 and capase-3 gene expression enhancing.
