Objective To review the experience of colon interposition in the treatment of benign esophageal stricture.Methods 58 patients who had undergone colon interposition for esophageal replacements were studied retrospectively,including 53 patients with corrosive burn esophageal strictures,3 traumatic esophageal strictures and 2 congenital esophageal strictures.The interposition colon for all patients went through substemum paths.Results There was no postoperative death in the duration of hospital stay.14 cases developed postoperative complication including 2 total colon necrosis,7 anastomotic leak,2 anastomotic stricture and 3 recurrent laryngeal nerve injury.52 patients were followed-up(ranged 1 to 16 years),40 cases were extremely satisfied(1 grade),9 very satisfied(2 grade),2 satisfied(3 grade)and 1 unsatisfied(4 grade).Conclusion Colon interposition is an ideal procedure for esophageal benign stricture.

Objective To study the clinic effects and safety of budesonide suspension combined with tubertaline solution for nebulization therapy on infantile asthma.Methods Seventy-five cases with asthma were divided into 3 groups randomly,double-blinded and controlled,each group having 25 cases.Group A inhaling tubertaline solution(bricanyl),while group B inhaling pulmicort respules combined with bricanyl,group C inhaling budesonide suspension(pulmicort respules)only.Results In group A,16 cases was cure,3 cases was markedly improved,6 cases was failure,the total efficacy rate was 76 percent.In group B,22 cases was cure,2 cases was markedly improved,1 case failed,the total efficacy rate was 96 percent.While in group C,14 cases was cure,4 cases was markedly improved,7 cases failed,the total efficacy rate was 72 percent.The difference of efficacy rate between group A and group B was significant(P0.05).Conclusion Pulmicort respules combined with bricanyl for nebulising inhalation is effective and safety on infantile asthma and its effect is better than inhaling bude-sonide or tubertaline only.

Objective To evaluate the efficacy of DICE regimen on relapsed or refractory NHL,and observe its toxicitv.Methods Records of 50 patients with relapsed or refractory invasive NHL were treated with DICE regimen.All patients had received at least 1 type of chemotherapy regimen with a median of 6 cycles.The patients received a median of 4 cycles of DICE regimen.Resuits The treatment outcome and adverse events of all patients were analyzed.The overall response rate was 48.0%.with a complete response (CR)rate of 16.0%.The response rates were 53.8%in the 26 patients with B-cell lymphoma and 29.2% in the 24 patients with T-cell lymphoma.The 1-and 2-year survival rates were 34.0%and 8.0%,respectively.The major adverse event was myelosuppression:the prevalence of grad eⅢ-Ⅳ neutropenia Was 38.0%,and that of grade Ⅲ-Ⅳ was 14.0%.One patient suffered grade Ⅲ liver toxicity.Conclusion DICE regimen Was effective for patients with relapsed or refractory invasive NHL, and its toxicity is well tolerated,but the response term is relatively short.Further clinical study on the application of DICE regimen iS needed.

Objective To investigate the effect of insulin on D_5 dopamine receptor expression and function in renal proximal tubule (RPT).Methods Immortalized RPT cells and D_5 receptor transfected HEK293 (HEK-D_5) cells were used in the study to investigate the effect of insulin on D_5 receptor expression and function,and those effects were compared in RPT cells from Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR). The function of D_5 receptor was determined by measurement of the Na~+-K~+-ATPase activity in HEK-D_5 cells. Results Insulin increased D_5 receptor protein expression in a concentration and time-dependent manner in WKY RPT cells,but not in SHR.The basal level of D_5 receptor expression was higher in WKY cells than that in SHR cells. Stimulation with fenoldopam(D_1-like dopamine receptor agonist) inhibited the Na~+-K~+-ATPase activity;pretreat- ment with insulin increased the inhibitory effect of fenoldopam on Na~+-K~+-ATPase activity in HEK-D_5 cells. Conclusion The abnormal regulation of insulin on D_5 receptor expression and function might be involved in the path- ogenesis of essential hypertension.

Objective To explore the serum level of gentamycin for orally in children with serious illness.Methods The serum level of gentamycin in 41 children who were in serious illness [multiple organ dysfunction(MODS)group with 21 cases and non-MODS group with 20 cases ] were monitored and the patients were treated with select decontamination of the digestive tract(SDD) from October 2004 to April 2005.Dosage:10 mg/(kg?d),orally taken three times(every 8 hours) one day.The blood after taking the drug one hour later in the fourth day was selected and the serum level of getamycin was monitored.Results Thirty-six children of 41 cases serum level of gentamycin were negative and 5 children(4 in MODS group and 1 in non-MODS group) who had alimentary tract hemorrhage were masccline in serum after taking gentamycin one hour later in the forth day.The absorption of gentamycin from enteric after orally was not(rela)-ted to MODS.There were statistics value between the gestrintestinal tract ulcer and serum level of gentamycin.Conclusions The safety for treating the children in serious illness with gentamycin for SDD is obvious.But we suggest to monitor the serum level of gentamycin for who has severe alimentary tract hemorrhage together with insufficiency of liver and kindey.

OBJECTIVE:To explore the difference of genotypes in patients with coronary artery disease(CAD)and different responses to clopidogrel. METHODS:Totally 159 CAD patients were selected from cardiology department of our hospital during Mar. 2013-Nov. 2015. They were given clopidogrel+aspirin for dual antiplatelet therapy for at least 1 year. Turbidimetry method was used to detect the percentage of platelet aggregation induced by adenosine diphosphate (ADP) and arachidonic acid (AA) before and after treatment. The polymorphism of cytochrome P450(CYP)2C19,CYP3A5,wild type leucine 33 allele(PLA1)/proline 33 al-lele(PLA2)were detected by PCR-RFLP. RESULTS:There were 3 kinds of CYP2C19 genotypes(2/2,2/1,1/1),3 kinds of CYP3A5 genotypes (3/3,3/1,1/1) and 3 kinds of PLA1/PLA2 genotypes (A1/A2,A2/A2,A1/A1);the frequency of each genotype was in line with Hardy-Weinberg balance(P>0.05). Among 159 cases,there were 81 cases of clopidogrelsemi-re-sponse,accounting for 50.9%;78 cases of clopidogrelresponse,accounting for 49.1%. The frequencies of CYP2C19 gene dele-tion(2/2 or 2/1 genotype)and 2 allele in clopidogrelsemi-responsepatients were significantly higher than clopidogrelre-sponsepatients,with statistical significance(P<0.05). The frequencies of PLA1/PLA2 gene deletion(A2/A2 or A1/A2 genotype) and A2 allele in clopidogrelsemi-responsepatients were significantly higher than clopidogrelresponsepatients,with statistical significance(P<0.05). The frequencies of CYP3A5 gene deletion(3/3 or 3/1 genotype)and 3 allele in clopidogrelsemi-re-sponsepatients were slightly higher than clopidogrelresponsepatients,without statistical significance (P>0.05). After treat-ment,the percentage of ADP or AA-induced platelet aggregation in different genotypes patients were significantly lowered,com-pared to before treatment;but the percentage of platelet aggregation in CYP2C19 gene deletion and CYP3A5 gene deletion patients were significantly higher than gene expression patients(1/1 genotype),with statistical significance(P<0.05). There was no sta-tistical significance in the percentage of platelet aggregation between PLA1/PLA2 gene deletion patients and gene expression patients (P>0.05). CONCLUSIONS:The incidence of clopidogrelsemi-responsein CAD patients is high. CYP2C19 and PLA1/PLA2 gene polymorphism may be related to clopidogrelsemi-re-sponse,while CYP3A5 gene polymorphism has no relation-ship with it. CYP2C19 and CYP3A5 gene deletion may weaken inhibitory effects of clopidogrel on platelet aggregation of CAD patients.

Background There is no effective method to regenerate the optic nerve after injury. It has been recently reported that α-crystallin could promote the survive rate and axon regeneration of retinal ganglion cells (RGCs) effectively. However,the molecular mechanism is not clear. Objective This study was to identify the site of RGCs where the exogenous α-crystallin bind to. Methods RGCs was isolated from retinas of two 2-day-old Long Evans rats and primarily cultured. The positive rate of the RGCs was assessed by counting the number of positive cells for fluorescently-labeled thy1. 1 and cy3 under the fluorescence microscope. The biotinylated exogenous α-crystallin was evaluated by direct coloration and the activity of molecular chaperones was measured by insulin test.After identifying the success of biotinylation along with the activity of molecular chaperones,biotinylated α-crystallin was co-incubated with RGCs and the cells then were reacted to fluorescently labeled avidin for the observation of binding site of exogenous α-crystallin under the laser confocal microscope. Results RGCs of 94% were survived through primary culture. The coloration of biotinylated α-crystallin labeled by the direct coloration method was more intensive, and the value of A450 descended as the decrease of biotinylated α-crystallin concentration,indicating that the α-crystallin was biotinylated successfully. The activity of molecular chaperones of biotinylated α-crystallin was significantly strong but no significant change after being biotinylated after co-incubation of RGCs with biotinylated α-crystallin. Laser confocal microscope examination revealed that co-incubated RGCs with biotinylated α-crystallin showed the red fluorescence on membrane and axon of RGCs rather than cytoplasm and nucleus. The absent response was seen in the control group. Conclusion Exogenous α-crystallin can specifically combine with the membrane of RGCs to play the biological function,but its binding mode and mechanism need further study.
