Methods Literatures in CBM, CNKI, VIP, WanFang databases were searched from the time of establishment of these databases till July 2010. Randomized controlled trials (RCT) of budesonide versus dexamethasone for the treatment of acute laryngitis in children were gathered, and quality was evaluated and meta-analysis was carried out. Results Eleven RCTs were identified, and meta-analysis indicated that there were significant differences between the two groups in the disappearing time of hoarseness, barking cough, dyspnea and laryngeal stridor. The MD values and their 95% CI were respectively -0.88 (-1.10, -0.65), -1.43 (-2.01, -0.84), -0.48 (-0.63, -0.32), and -0.59 (-0.78, -0.41). Conclusion Based on current evidence in China, budesonide is better than dexamethasone for the improvement of acute laryngitis in children.
Objective To establish the rat orthotopic liver transplantation model by characterizing the blood supply of hepatic artery with the Cuff skill and the modified arterial sleeve anastomosis, to explore the possible mechanisms of acute rejection and the express of Fractalkine (Fkn) in the early stage after hepatic allograft operation. Methods SD rats were selected as donors and Wistar rats as receptor for the rejection model of orthotopic liver transplantation. Recipient rats were divided into 2 groups randomly after operationand the drugs were given intraperitoneally once a day in each group. In the experimental group, cyclosporine A (CsA) was delivered with 3 mg/kg. In the control group, only normal saline was given with 3 ml/kg. Condition of survivals were observed. The rejection actvity index (RAI) and the expression of Fkn of liver tissue were observed after 3rd, 5th and 7th days in 5 rats. The rest of rats in each group were fed and given drug or normal saline until they were died and the mean survival time were recorded. Results There were 18 survivals in control group, and 19 in experimental group after liver transplantation. Condition of survivals in experimental group was better than that of control group. The mean survival times of experimental group(19.50±4.51 days) was significantly longer than that of control group(7.60±1.60 days), showing statistically significant difference (P＜0.05). After 3rd, 5th and 7th days of transplantation, RAI of control group were 3.80±0.35,5.90±0.87 and 7.50±1.30,respectively;RAI of experimental group were 3.10±0.21,3.90±0.41 and 4.50±0.52.Therewasstatistically significant difference in RAI between 2 groups on the 7th day after transplantation (Plt;0.01). On the 3rd,5th and 7th days after transplantation, the Fkn of control group was 8.20±0.57,21.30±3.30 and 25.70±4.91, and that of experimental group was 8.30±0.56,10.30±0.67 and 11.70±1.23. There were statistically significant differences in Fkn between 2 groups on the 5th, 7th days after transplantation (Plt;0.01). Conclusion Fkn is a participant inacute rejection after the rat orthotopic liver transplantation and can be chosen as a useful target in the diagnosis of acute rejection. CsA has immunosuppressive property in the condition of acute rejection in the rat orthotopic liver transplantation, which may be result from the decreased the level of Fkn.
【Abstract】Objective To investigate the protective effect of improving the pancreatic ischemia and calcium channel blockers on preventing the progression of acute pancreatitis. Methods Twenty-four patients with mild acute pancreatitis were randomly divided into two groups： control group and treated group. Within the first 72 hours from the onset of AP, routine conservative managements were performed in control group, improving the pancreatic ischemia and preventing Ca2+ overload were performed in treated group for two weeks. The hemorrheological parameters were measured at 1,4,7,14 days after adimission, simultanously, serum TNFα, IL-1β, C-reactive protein and plasma TXB2, 6-keto-PGF1α levels were determined with ELISA methods. Results The hemorrheological changes were improved in treated group, serum TNFα, IL-1β, C-reactive protein and plasma TXB2, 6-keto-PGF1α levels were significantly decreased each time point in treated group as compared with control group. Conclusion Improving the pancreatic ischemia and calcium channel blockers have protective effect through reducing the generation of cytokines and inflammatory mediators on preventing the progression of acute pancreatitis.
Objective To investigate the relationship between early fluid management and the conversion rate to surgery in patients with sever acute pancreatitis( SAP) .Methods The patients with SAP admitted in ICU in West China Hospital from July 2005 to June 2010 were retrospectively analyzed. They were divided into four groups according to the quartile of the accumulated fluid balance in the first three days after admission in ICU( lt; 25% , 25% ～50% , 50% ～75% , and gt; 75% , respectively) . The major demographic data, clinical characteristics, mortality, and conversion rate to surgery were evaluated respectively. Results 208 patients were enrolled. For each quartile, the conversion rate to surgery decreased at first, and then increased along with the increase of the accumulated fluid balance. Significant difference existed between the second quartile with the lowest conversion rate to surgery and other three quartiles ( P lt; 0. 05) . Differences were also found in mortality and the score of acute physiology and chronic health evaluation Ⅱ( APACHEⅡ) on 24th and 48th hour between the first three quartiles and the last quartile with the highest mortality and APACHⅡ score( P lt;0. 05) . However, sex ratio, age, Ranson criteria, and the score of sequential organ failure assessment( SOFA) did not have significant differences among each quartile( P gt; 0. 05) . Conclusion Fluid management in early stage can influence conversion rate to surgery and mortality in patients with SAP.

Objective To investigate the efficiency of combining traditional Chinese medicine with western medicine in the treatment of severe acute pancreatitis (SAP). Methods The clinical results of sixty three cases of SAP of non-operative treatment with injection of Salia miltorrhizae composita, and oral or gastric tube feeding of decoction Qing-Yi-Tang were retrospectively studied. Results Thirty four cases were categorised as SAP Ⅰ grade, and 29 cases as SAP Ⅱ grade. A variety of complications occurred in 19 cases (30.16%), 3 patients died (4.76%), and 4 patients developing abscess of pancreas (6.35%) which had to be operated on.Conclusion The individualization principle on the basis of cause and clinical stage of the disease should be stressed in treating SAP. The patients who had complication needing to be operated on should be timely performed. There is a good efficiency in the treatment of SAP with the traditional Chinese medicine combining with western medicine.
【Abstract】Objective To study the liver injury and effects of aescin on liver in rats with acute pancreatitis. Methods The rats were divided into 3 groups (control group, AP group and aescin group). The serum alanine aminotransferase （ALT）, serum lactate dehydrogenase (LDH), hepatic cellular energy charge (EC) and adenosine triphosphate (ATP) were detected. The pathologic changes in pancreas and liver were also observed. Results The serum levels of ALT and LDH in aescin group were significantly lower than those of the AP group. The EC and ATP levels were significantly higher in aescin group than that of the AP group. Conclusion Introvenous injection of aescin can alleviate the liver injury in rats with acute pancreatitis.
Objective To summarize the cl inical appl ication and experience of repairing acute avulsion-type achilles tendon rupture by locking-loop stereoscopic suture. Methods Between January 2006 and June 2010, 41 cases of acute avulsion-type achilles tendon rupture were treated by locking-loop stereoscopic suture. Among 41 patients, 33 were male and 8were female with an average age of 41 years (range, 18-56 years); the locations were left side in 27 cases and right side in 14 cases. There was palpable defect in 33 cases, 7 cases underwent B-ultrasound, and 1 case underwent MRI to confirm the diagnosis. The time from injury to operation was 36 hours to 7 days. All cases were restored by locking-loop stereoscopic suture. Results All incisions healed by first intention. Thirty-one cases were followed up 12 months to 3 years and 10 months with an average of 17 months. The muscle strength reached grade 5; the patients could walk normally, and the heel raising was powerful at 1 year after operation. The circumference difference between wrong leg and good leg was less than 3 cm, and the ankle dorsiflexion was 20-30°, plantar flexion was 40-50°. No re-rupture of achilles tendon or deep infection occurred during follow-up period. At last follow-up, according to evaluation of curative effects by Arner-Lindholm standard, the results were excellent in 21 cases and good in 10 cases with an excellent and good rate of 100%. Conclusion Locking-loop stereoscopic suturing is a safe and effective method with avulsion-type control abil ity, tensile strength, l ittle effect on the blood supply of the achilles tendon for repairing acute avulsion-type achilles tendon rupture.
