Objective: Enteral nutrition was used to correct the malnutrition in the patients suffered from esophageal rupture postoperatively. Methods: The naso intestinal tube was placed during operation and the enteral nutrition was used postoperatively. The albumin, prealbumin and transferrin were measured before and day1, 5, 8 and 12 after operation. Results: All 27 patients were discharged with no death. Albumin, prealbumin and transferrin decreased on the 1st day postoperatively and reached the preoperative level on the fifth postoperativeday. Conclusion: Enteral nutrition plays an important role in the postoperative treatment for esophageal rupture.

OBJECTIVE:To discuss the accuracy of detecting tacrolimus(FK506) concentration in whole blood by ELISA and its application in organ transplantation.METHODS:The ELISA was used to detect FK506 valley point concentrations in 5 liver transplanted recipients at different postoperative periods .Based on the results combined with clinical findings, the dosages were adjusted.The accuracy of the method and guidance action in FK506 clinical application were described.RESULTS: In 131 detections of 350 samples, the results of quality control samples were all in the control range .The detecting RSDs of high and low concentration quality control samples were 9.09% and 11.90%, respectively.The control range of FK506 concentrations in whole blood were similar to that reported in literature .CONCLUSION :ELISA is a sensitive and specific method for routine FK506 concentration monitoring in whole blood,which is suitable for application in hospital.

Objective To evaluate the diagnostic accuracy of diffusion tensor imaging (DTI) of corticospinal tract in amyotrophic lateral sclerosis (ALS) and find optimal testing strategies and optimal cutoff values of DTI indices for individual patient discrimination.Methods Thirty-three ALS patients and 34 healthy controls,collected at Peking Union Medical College Hospital from June 2004 through July 2005,undergoing brain DTI studies and fractional anisotropy (FA) examinations along the corticospinal tract,were analyzed by receiver operating characteristic (ROC) curves.Results Compared with the controls,ALS group had significantly decreased FA values in subcortical white matter of the precentral gyrus,the posterior limb of the internal capsule and the cerebral peduncle.In ROC analysis,the average FA value of the former two positions showed the best performance with an area under the curve of 0.917,an optimal cut-off value of 0.604,a sensitivity of 0.759 and a specificity of 0.912.The corresponding data for the average FA of all the three positions and each single position were listed as follows:average of three 0.914,0.648,0.759,0.912; precentral gyrus 0.875,0.509,0.733,0.824; internal capsule 0.845,0.692,0.656,0.941 ; and cerebral peduncle 0.752,0.742,0.656,0.735.Conclusions FA values of the corticospinal tract have a good accuracy in detecting upper motor neuron involvement in ALS.Precentral gyrus and posterior limb of the internal capsule and the average FA values of these two positions were suggested as the preferred testing places and DTI indices for clinical use.

ObjectiveTo investigate the influence of fast track surgery (FTS) on insulin resistance indexes in esophageal cancer patients.MethodsA total of 68 esophageal cancer patients receiving radical operation in our hospital from November 2009 to March 2011 were randomly divided into 2 groups by envelope method:FTS group ( n =34) and control group ( n =34 ).The postoperative first passage of gas by annus and defecation,postoperative hospital stay,hospitalization expenditure,and postoperative complications were recorded.Insulin resistance indexes were measured before operation as well as on the 1st,3rd,and 7th postoperative days,including fasting blood-glucose (FBG),fasting insulin (FINS),serum level of interleukin-6 (IL-6),and C-reactive protein (CRP).The insulin resistance index (HOMA-IR) was calculated at the same time points.ResultsThe postoperative time of first passage of gas [ ( 1.91 ± 1.13 ) d vs.(2.95 ± 1.25 ) d,P =0.000 ] and defecation [ ( 3.75 ± 1.54 ) d vs.(4.84 ± 1.76) d,P =0.007] in FTS group were significantly shorter compared with control group,and the total hospitalization expenditure was significantly lower in FTS group [ (3.19±0.42) ten-thousand yuan vs.(3.98 ±0.36) ten-thousand yuan,P =0.000 ].The preoperative insulin resistance indexes showed no signifcant differences between the two groups ( all P ＞ 0.05 ).One day after operation,the levels of log-HOMA-IR (0.97 ± 0.52vs.1.54±0.57,P=0.000),FINS [ (11.87±4.55) μU/ml vs.(17.16±6.90) μU/ml,P=0.000],IL-6[ (124.15±21.39) ng/Lvs.(138.78±23.60) ng/L,P.=0.009],and CRP [ (62.92±14.78) mg/L vs.(71.07 ± 14.51 ) mg/L,P =0.025 ] in FTS group were significantly lower than those in control group.Three days after operation,the levels of log-HOMA-IR (0.86 ± 0.47 vs.1.27 ± 0.58,P =0.002),FINS [ ( 9.56 ± 4.37 )μU/mlvs.(14.91±6.54) μU/ml,P=0.000],IL-6 [ (140.94±25.12) ng/Lvs.(153.89±24.06) ng/L,P=0.035],and CRP [ (138.59 ±21.61) mg/L vs.(153.17 ±25.20) mg/L,P=0.019] in FTS group were significantly lower than those in control group.Seven days after operation,the level of CRP in FTS group was significantly lower than that in control group [ (53.07 ± 15.84 ) mg/L vs.( 61.59 ± 16.28 ) mg/L,P =0.032 ].ConclusionFTS may promote the early recovery of gastrointestinal function,reduce stress reaction and postoperative insulin,thus being conducive to fast rehabilitation of esophageal cancer patients.

Objective:To investigate the curative efficacy of combined use of dexamethasone palmitate,vitamin B12 and lidocaine in the treatment of knee osteoarthritis and its effects on the seum levels of interleukin-1 (IL-1),matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-1 (TIMP-1).Methods:84 patients with osteoarthritis of knee were selected from August 2014 to July 2015 in Sixth Affiliated Hospital of Xinjiang Medical University and divided into the observation group and the control group according to the order of admission,42 cases in each group.The observation group was given intra-articular injection of dexamethasone palmitate,vitamin B12 and lidocaine,and the control group was treated with traditional Chinese medicine.The clinical efficacy was evaluated after treatment.The changes of serum IL-1,MMP-3,TIMP-1 levels and visual analogue (VAS) score were compared before and at 1 months after treatment.Results:After treatment,the total effective rate of observation group was significantly higher than that of the control group (P＜0.05),the serum levels ofIL-1,MMP-3 levels and VAS score were significantly lower than those before treatment,serum TIMP-1 level was obviously higher than that before treatment(P ＜0.05),the serum levels of IL-1,MMP-3 levels were significantly lower in the observation group than those of the control group,while the serum TIMP-1 level was obviously higher than(P＜0.05) Conclusion:Intra-articular injection with dexamethasone palmitate,vitamin B12 and lidocaine could effectively decrease the levels of serum IL-1 and MMP-3,increase the level ofTIMP-1,and relieve the pain in the patients with knee osteoarthritis.
