Clinical diagnosis and treatment of constipation lags behind relatively with unsatisfactory efficacy. Pathogeneses and molecular mechanisms for different types of constipation are waiting to be further clarified. New biomarkers and therapeutic targets for clinical diagnosis of constipation are so urgent. As for current problems in diagnosis and treatment of constipation, it is necessary to use the concept of translational medicine to break existing imprisonment of thinking, and find out new thinking ways of research methods, diagnosis and treatment approaches, thereby improving diagnosis and treatment levels.

OBJECTIVE: To establish a population pharmacokinetic model of intravenous infusing busulfan in HSCT patients, and to explore physiological and pathological factors which may influence the pharmacokinetic parameters. METHODS: We have collected clinical history information of 35 patients undergoing HSCT surgery and taking busulfan intravenous infusion for treatment. These information such as physiological and pathological factors and busulfan concentration data were used to perform the population pharmacokinetic analysis by applying the method of nonlinear mixed effects modeling(NONMEM). RESULTS: A statistical model of busulfan is established, including variables such as body weight, sex, serum creatinine clearance. The success of 973 out of 1 000 times resampling trials (by bootstrap) shows that the newly parameters value are very close to the estimate value calculated from the final model by NONMEM, which demonstrates the established population pharmacokinetic model of busulfanis stable, effective and predictable. CONCLUSION: The population pharmacokinetic model is established, which is capable of depicting the pharmacokinetic characteristics of busulfan. It is found that patients' weight, gender and creatinine clearance influence pharmacokinetic parameters, which can be useful and valuable for the clinical individualized dosing regimens.

Objective To study the relationship of expression of central cortex glucocorticoid receptor (GR) at protein level with GR expression in the liver at protein level and with changes of serum cortisol and adrenocorticotropic hormone (ACTH) following severe closed traumatic brain injury (TBI) in mice. Methods Severe TBI was established in awake mice by using a BIM-Ⅲ biomechanical machine. At 0.5, 2, 8, 24, 48 and 72 hours after TBI, the total cytosolic GR in the cortex and liver were detected with Western blotting. Levels of serum ACTH and cortisol were measured by ELISA technique and radio-immunological assay (RIA) respectively. Results The expression of GR both in the cortex and liver were obviously down-regulated at protein levels at 2-72 hours after TBI and increased slowly eight hours after injury. The GR in the liver showed no recovery at 72 hours after injury and that in the cortex was decreased continually at 24 hours after injury. Serum ACTH and cortisol levels were increased markedly compared with control group, when there were two different peaks in the observation curve.Conclusion There is glucocorticoid resistance both in the central and peripheral tissues after severe closed TBI in the awake mice, which changes in a time-dependent manner.

Objective To investigate the expressions and clinical significance of Id1 in diffuse large B‐cell Lymphomas (DL‐BCL) tissue and Id1 gene in bone warrow cell .Methods Forty cases of DLBCL(observation group) and 25 cases of reactive lymph‐oid hyperplasia (control group) were included in this study which were admitted by our hospital from October 2011 to October 2014 .The expression of Id1 proteins in DLBCL and reactive lymphoid hyperplasia were detected by imunohistochemical technique . The expression of Id1 genes in all patients′marrow cells was detected by reverse‐transcriptase polymerase chain reaction .The data were collected and analyzed by designed person .Results In 40 DLBCLs ,the positive rate of Id1 were 75 .00% (30/40) ,which was higher than in RHs 32 .00% (8/25) ,with statistic difference(P= 0 .001) .Id1 protein was not correlated with sex and age(P>0 .05) ,but was correlated with clinical stage ,LDH level and extranodal infiltration(P<0 .05) .The expression of Id1 genes in mar‐row cells in DLBCL was higher than in RH (Id1mRNA level 2 .80 ± 0 .87 vs .1 .37 ± 0 .51 ,P<0 .05) ,and also correlated with clini‐cal stage ,LDH level and extranodal infiltration(P<0 .05) .Conclusion The expression of Id1 proteins and genes are much higher in DLBCL tissue and marrow and probably related to the prognosis of DLBCL .This discovery would contribute to predicting prognosis of DLBCL ,w hich also could be a therapeutic target of DLBCL in the future .

AIM: To investigate the phenomenon that miR-let-7d regulates the proliferation and invasion abilities of the lung cancer cells through nuclear receptor peroxisome proliferator-activated receptors γ (PPARγ).METHODS: The relation between PPARγ and microRNA was analyzed by bioinformatics.The plasmid reporter assay was used to verify that PPARγ was the target of miR-let-7d.The lung cancer cell line with low expression of PPARγ was selected from different lung cancer cell lines by Western blot.The regulatory role of miR-let-7d in the lung cancer cells was determined by dual luciferase labeling and Western blot.The effect of miR-let-7d on the proliferation ability of lung cancer cells was detected by colony formation assay, the effect of miR-let-7d on the invasive ability of lung cancer cells was detected by Transwell invasion assay.RESULTS: The results of bioinformatic analysis showed that miR-let-7d regulated the expression of PPARγ, and the 3'UTR of PPARγ contained 2 functional miR-let-7d binding sites, indicating that PPARγ is a direct target of miR-let-7d.miR-let-7d was able to directly regulate the expression of PPARγ at mRNA and protein levels.Transfection of miR-let-7d inhibitor promoted the proliferation and invasion abilities of lung cancer cells by increasing the expression of PPARγ.CONCLUSION: miR-let-7d increases the expression of tumor suppressor PPARγ to inhibit the proliferation and invasive abilities of lung cancer cells.

AIM:To study pentoxifylline(PTX) prevention against renal ischemia-reperfusion injury in rabbits. METHODS: 50 New Zealand rabbits were randomly divided into 5 groups: sham operation groups, ischemia-reperfusion injury group(I/R), I/R+hypothermia group, I/R+PTX group and I/R +PTX+hypothermia group. Except the sham operation group, the rabbit left renal arteriae were blocked with bulldog clamps for 60 min. The left kidney was removed after 24 h. The activity of SOD, the content of MDA of kidney tissue homogenate, BUN and SCr in the blood were detected, meanwhile the pathological structure were observed. RESULTS: In I/R group, the renal tubule showed hydropic degeneration, hemorrhage and necrosis. A large number of inflammatory cells were infiltrated in the hemorrhage and necrotic tissue. The mitochondria of the proximal convoluted tubule epithelium were shown to be swollen highly, and the crisallia extremely confused, vague, disappeared. The injury was reduced in I/R+PTX group and I/R+hypothermia group. It was normal in the I/R+PTX+hypothermia group and sham group. The BUN, SCr, MDA in I/R group rised obviously and the activity of SOD was reduced significantly 24 h after reperfusion( P 0.05). CONCLUSION: PTX has a protective effect against renal ischemia-reperfusion injury.
