ObJective To acknowledge the sleep status of infants and analyze the influencing factors of sleep problems in them. Methods The sleep status of 136 infants and its influencing factors were investigat-ed using questionnaires, the results underwent descriptive analysis, single-factor analysis and multifactor anal-ysis. Results Difficulty in falling asleep was the major sleep problems, then was frequent night awakening. The influencing factors included: family type, education degree of the parents, inhabited environment, the feed-ing mode after birth, the period of supplementary protein dietary addition, the times of taking food through the night, and the sleep position, the bed, the emotion when falling asleep, etc. Conclusions Sleep problems is ubiquity in infants,and the unproper child rearing behaviors is the major influencing factor. In order to prevent sleep problems in infants and improve the quality of sleep in them, the parents need health guidance.

Objective:Cholangioduodenal reflux is still an unresolved problem in interposed jejunal choledochoduodenostomy (IJC) yet.To settle this problem,we designed IJC with distal suspending (IJCDS).Methods:IJCDS is to insert and suspend the distal end of the 25 cm-ling interposed jejunum to the duodenal cavity,which is about 2.5 cm long.The pressure of the biliary tract and the biochemical composition or the bile were measured during and after the operation and the results were compared.Barium meal and cholangiography through T tube were performed after the operation.Follow-up surveys were also done.Results:The pressure or the biliary tract decreased distinctively after the operation.Barium meals found no cholangioduodenal reflux although the patients had changed many postures.Cholangiography through T tube showed parisaltic or the interposed jejunum and the contrast medium was continuously pushed into the duodenum.Noreflux cholangitis and stone recurrence were found in the follow-up survey in 14 patients.Conclusion:IJCDS has the powerful function on preventing cholangioduodenal reflux.On the other hand,it avods the shortcomings of other reflux-preventing operative pattern.So it had the good prospect to extend its clinical usage.

At present,transplantation has been the predominant way to solve most of the end-stage diseases,ensued by the use of immunosuppressive drugs.Since the immunosuppressive drugs have narrow therapeutic index,the blood drug concentration is needed to mornior.Pharmacogenetics is one subject which focuses on the interaction between gene and the metabolism of the drug,providing great help for designing the regime of achieving the target drug concentration.Meanwhile,it facilitates the realization of individual therapy.This review thus focuses on the latest advancement on the pharmacogenetics of those immunosupprressants,hoping to provide help for the treatment.

Objective To investigate the curative effect and safety of microinvasive percutaneous nephrolithotomy (MPCNL) and ureteroscope lithotripsy (URSL) in treatment of children′s (≤6 years old) middle and upper segment ureteral calculi. Methods Eighty children (≤6 years old) with middle and upper segment ureteral calculi were selected, and they were divided into observation group and control group according to random number table method with 40 cases each. The children of observation group were treated with MPCNL, and the children of control group were treated with URSL. The operation time, hospitalization time, calculi clearance rate of the first phase, decline situation of the postoperative hemoglobin and hematocrit and complication were compared between 2 groups. Results The operation time and hospitalization time in observation group were significantly shorter than those in control group:(45.43 ± 9.76) min vs. (68.32 ± 11.28) min and (8.12 ± 1.03) d vs. (13.45 ± 2.34) d, the calculi clearance rate of the first phase was significantly higher than that in control group: 100.0% (40/40) vs. 62.5%(25/40), the incidence of complication was significantly lower than that in control group:20.0%(8/40) vs. 60.0% (24/40), and there were statistical differences (P<0.05). There were no statistical differences in the decline situation of the postoperative hemoglobin and hematocrit between 2 groups (P>0.05). Conclusions The MPCNL in treatment of children′s middle and upper segment ureteral calculi has short operation time, high calculi clearance rate of the first phase, and low incidence of perioperative complication. Compared with URSL, the URSL is safe and efficient, and it is worthy of clinical application.

Objective To investigate the changes of proteins expressions in intestinal mucosa of rats after is chemic postconditioning (IPo) against intestinal ischemic/reperfusion (Ⅱ/R) injury of intestine in order to elucidate its potential mechanisms of protective role. Methods Sixteen SD rats were randomly divided into Ⅱ/R group and IPo group ( n = 8). Rats of both groups received an episode of ischemic/reperfusion insult to intstine that was made by occlusion of the superior mesenteric artery (SMA) for 60 minutes. Rats of IPo group underwent three additional episodes of clamping SMA on for 30 seconds and off for 30 seconds successively after prolonged reperfusion/reperfusion of intestine. The intestinal mucosa was taken by scratching immediately after reperfusion in both groups, and total proteins were separated by immobilized pH gradient (IPG) based two-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed using Image Master 2D Elite 5.0 image analysis software, and the proteins were cut out from the gel and then identified using MALDI-TOF-MS. The biological information of these proteins was looked for in the database of these peptide mass finger-printing (PMF) .Results Ten differentially expressed proteins were found, of which 6 were up-regulated and 4 were down-regulated in IPo group. Nine proteins were identified and characterized by their bioelements including aldose reductase and aldehyde dehydrogenase that were related to anti-oxidative stress and inhibition of cell apoptosis. Conclusions The well-reproducible 2-DE profiles of intestinal mucosa in II/R and IPo groups were established. The potentially protective effects of IPo may be attributed to up-regulating protein expressions of aldose reductase and aldehyde dehydrogenase, and thereby suppressing oxidative stress and cell apoptosis.

Objective To detect the level of plasma microRNA-1 (miR-1) in acute myocardial infarction (AMI) and compare the diagnostic values of it with that of cardiac troponin T (cTnT).Methods During 2011-05 to 2012-05,there were fifty-six plasma samples taken from patients with AMI and twenty-eight plasma specimens got from non-AMI controls were analyzed.The expression of plasma miR-1 was measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR),and the level of plasma cTnT was measured by using electrochemiluminescence-based methods on the Elecsys 2010 Immunoassay Analyzer.Then,the SPSS 16.0 was used for the statistical analysis.Data were presented as means ± standard deviation unless otherwise described.The differences about clinical characteristics between AMI patients and controls were tested using Student' s t-test or Fisher' s exact test.The Mann-Whitney test was conducted to compare the expression of microRNAs between the AMI patients and controls.The comparison of microRNAs expression between different intervals of AMI patients was done using Wilcoxon signed rank test.The receiver operating characteristic (ROC) curve was established to discriminate AMI patients from controls.Results The expression of plasma miR-1 was significantly increased in AMI patients (P ＜ 0.01) compared with healthy controls.The contents of the plasma miR-1 in AMI patients fell down nearly to the normal level at 14 days (P ＞ 0.05).There was no relevance between the expression of plasma miR-1 and the clinical characteristics of the study population (P ＞ 0.05).Moreover,ROC curve analyses demonstrated that miR-1 had the specificity and sensitivity for the diagnosis of early AMI,but was not superior to cTnT.Conclusions Our results showed that plasma miR-1 had the capacity in early diagnosis of early AMI,and can be biomarker for AMI,however,miR-1 is not superior to cTnT for the diagnosis of AMI.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.
