BACKGROUND: Rat model of orthotopic liver transplantation is a very valuable model for experimental study in liver transplantation including organ preservation, tissue ischemia-reperfusion injury, allograft rejection and immune tolerance mechanism. Stable liver transplantation animal model is the basis of the related experimental studies. However, its experimental operation is long and boring, especially performed by a single operator under direct vision. OBJECTIVE: To investigate the operation techniques to establish a stable rat model of orthotopic liver transplantation by a single operator under direct vision. METHODS: The orthotopic liver transplantation was performed using two-cuff method in 50 pairs of rats. We exposed the abdominal cavity fully, perfused the donor liver through abdominal aorta without flipping donor liver; suprahepatic inferior vena cava was in vivo cut down using one-step method, without diaphragm ring; the suprahepatic inferior vena cava was anastomosed with single-row suture, and the cuff of portal vein was installed by fixing the blood vessel forceps on rubber. Hepatic artery was not reconstructed. Fluid replacement was administered to maintain hemodynamic stability in rats after operation. RESULTS AND CONCLUSION: The donor operative time was (36.2± 2.5) minutes, donor liver trimming time was (12.2± 1.5) minutes, receptor operative time was (45.6 ± 3.5) minutes, suprahepatic inferior vena cava anastomosis time was (10.1 ± 2.1) minutes, portal vein cuff time was (1.5 ±0.9) minutes, infrahepatic inferior vena cave cuff time was (1.1 ± 0.6) minutes, anhepatic phase was (15.1 ± 2.2) minutes. The success ratio of the operation was 100% and the survival rates within 1 week and 1 month were all 100%. It is indicated that the key factors of a successful model were stable anesthesia, good donor liver perfusion, adequate exposure, skilled microsurgical technology and vascular anastomosis technique.

Objective To explore the expression of drug transporter organic anion transporting polypeptide2(Oatp2) and P-glycoprotein(P-gp) in brains of chronic epileptic rats induced by lithium-pilocarpine.Methods Chronic epilepsy modles were elicited after status epilepticus(SE) induced by lithium-pilocarpine in adult Wistar rats.The expressions of Oatp2 and P-gp were detected by immuno-histochemistry(SABC) method.Results Positive expression of Oatp2 was predominantly in the plexus epithelial cells and(blood-brain) barrier endothelial cells.Weak staining for Oatp2 was also detected in the neurocyte.In contrast,apparent expression of(P-gp) was seen in brain capillary and neurocyte only.Compared with normal control rats,expression of Oatp2 on the plexus epithelial cells and brain capillary in chronic epileptic rats was significantly decreased(P

Bronchiolitis obliterans(BO) is chronic airflow obstruction syndrome characterized by small airway obstruction and airflow limitation.In children, BO is secondary to severe infection of respiratory tract, and its development is related with inflammation and immune response.At present, the diagnosis of BO mainly is depended on the clinical manifestation, lung function and examination results of high resolution computed tomography (HRCT) because of difficulty of lung biopsy.Pulmonary HRCT is a non-invasive examination, and worthy of generalization.Currently, BO has no accepted effective treatment,early diagnosis and treatment can block the progression of BO.Due to lack of realization of BO, doctors and parents fail to give enough attention, BO has a prolonged course and very poor prognosis.

The widespread use of antibiotics has been effectively controlled serious life-threatening infections.The trituration,exploitation and use of antibiotics has been rapidly developed and applied to many fields.Due to the extensive use of various antibiotics,the emergences of drug-resistant bacteria and the rates of bacterial resistance have increased unceasingly which has been a common focus in the world.Resistant pathogen can reduce the effectiveness of antibiotics,and which is a serious threat to human health.De-escalation therapy of antibiotics can quickly and effectively control serious infections,and avoid bacterial resistance,and induce fungal infections.The rational use of antibiotics in pediatrics is very imperative,which includes strengthening management of antibiotics,and improving awareness and vigilance of the adverse reactions of antibiotics,and consummating specification of medication.Then,realize the correct,safe,rational medication of antibiotics.

Objective: To research the comparability of water vapor transmission of laminated films for pharmaceutical packaging determined by different instruments, methods and experimental conditions to provide reference and advice for the related inspection personnel.Methods: The principle, test parameters, conditions and scope of application for the testing methods for water vapor transmission in the national standard (GB) and international standards (ISO, ASTM) were compared by using three kinds of instruments based on different testing principles.Results: Different temperature and humidity conditions had great influence on the results of the same instrument.Under the same temperature and humidity, the instrument with different principles had little influence on the test results.Conclusion: Testing personnel should regularly use the standard membrane to calibrate the instrument of the sensor method.The temperature and humidity should be strictly controlled during the test.They should take measurement accuracy, personnel operation and economic loss into consideration to select the suitable method.

Since 1950s,the idea of liver transplantation (LT) was proposed,the technique of LT had been gradually and widely applied in the field of surgery.The development of LT experienced three stages,including animal experiment,clinical probation and clinical application.It is well known that LT is the only effective therapeutic method for terminal stage of liver diseases.In liver transplantation,the ischemia-reperfusion injury is difficult to avoid,and an important factor causing poor liver function.Meanwhile,hemodynamic volatility and internal environment disorder are important prognostic factors.How to reduce ischemia-reperfusion injury of the transplanted liver and improve intraoperative hemodynamic changes in liver transplantation is a clinical research focus.Recent studies has indicated that orthotopic liver transplantation retrograde perfusion method can effectively reduce the transplanted liver ischemia-reperfusion injury and improve liver function early after transplantation,and thus significantly improve the success rate of liver transplantation and survival.

Objective To investigate the distribution and duration of abnormal blood glucose level in SGA infants. Methods Blood glucose level was systemicly monitored in 37 SGA infants for (133?115) h(range 16～524 h, median 93 h), who were non NICU hospitalized and no feeding or IV infusion when admitted at (2 6?2 4) h (range 0.25~10.0 h, median 2.0 h) of age. Results During monitoring period, there was hypoglycemia in 19 cases (51%),hyperglycemia in 2 cases (5%), and both hypo and hyperglycemia in 3 cases (8%). The median of last time abnormal glucose level appeared was 10 hr after birth, its 95% confidence interval was 5~55hr after birth. Multiple regression analysis shown delivery models bad relationship with glucose level at admition (p= 0.013). The blood glucose level was higher in vaginal delivery babies. The lower the birth weight (BW)was, the longer the duration of abnormal glucose level lasted ( O
