Objective: To observe the therapeutic action of earth enteral nutrition after jejunum interposition in patients with carcinoma of gastric cardia.Methods: Sixty-two patients after jejunum interposition were divided into early enteral nutrition group(n=33) and parenteral alimentation group(n=29).The clinical observation index and nutrition index were compared between the two groups.Results: The enteral nutrition group had more advantages than the parenteral alimentation group in the aspects of clinical observation index postoperative complication and nutrition index.Conclusion: Early enteral nutrition could improve gastrointestinal function and nutritional state and decrease the incidence rate of postoperative complication.

Objective To construct mouse model of acute myeloid leukemia and detect the expression of ANGPT 1 ,ANGPT2 and VEGF gene on the cells its as well as the clinical significance .Methods The HL‐60 cells were transfected to NOD/SCID mouse through abdominal injection to construct mouse model of acute myeloid leukemia .Then identify mouse model by histopathology and Flow Cytometry .The expression of ANGPT2 ,ANGPT1 and VEGF mRNA in the tumor tissues of mouse model was detected by real‐time fluorescence quantitative PCR .The expression of ANGPT2 will be analyzed on the survival time of mouse model by Spearman′s correlation method .Results Mouse model has been successfully identified by histopathology and Flow Cytometry .The expression of ANGPT2 and VEGF in mouse mode was significantly detected ,which was that of higher than normal group (P<0 .05) .The expression of ANGPT1 was lower than that of ANGPT2 and VEGF ,there was no significant difference between AN‐GPT1 and normal groups (P>0 .05) .The higher expression of ANGPT2 in mouse model had a short survival time in mouse with acute myeloid leukemia .Conclusion This study showed that ANGPT2 mRNA was over‐expressed in acute myeloid leukemia .The increasing expression of ANGPT2 mRNA may lead to poor prognosis in mouse with acute myeloid leukemia .

Two isomers of nitrochlorobenzene (o-, and p-NCB) were treated by a Pd/Fe catalyst in aqueous solutions through catalytic amination and dechlorination. Nitrochlorobenzenes are rapidly converted to form chloroanilines (CAN) first through an amination process, and then rapidly dechlorinated to become aniline (AN) and Cl(-), without the involvement of any other intermediate reaction products. The amination and dechlorination reaction are believed to take place predominantly on the surface site of the Pd/Fe catalysts. The dechlorination rate of the reductive degradation of the two isomers of nitrochlorobenzene (o-, and p-NCB) in the presence of Pd/Fe as a catalyst was measured experimentally. In all cases, the reaction rate constants were found to increase with the decrease in the Gibbs free energy (correlation with the activation energy) of NCBs formation; the activation energy of each dechlorination reaction was measured to be 95.83 and 77.05 kJ/mol, respectively for o- and p-NCB. The results demonstrated that p-NCBs were reduced more easily than o-NCBs.

Objective To evaluate the effect of bone mesenchymal stem cells (BMSCs) on lidocaine-induced apoptosis in dorsal root ganglion cells (DRGCs) of rats in vitro.Methods DRGCs in the logarithmic phase were incubated in culture plates at the density of 2 × 104 cells/cm2 (27 wells in total).DRGCs were randomly divided into 3 groups (n =9 each) using a random number table:control group (group C),lidocaine treatment group (group L) and BMSC treatment group (group B).The DRGCs in group C were incubated routinely without lidocaine,while the DRGCs were incubated for 2 h with lidocaine with the final concentration of 50 mmol/L in L and B groups.The DRGCs were then incubated normally in group L.The DRGCs were then co-cultured with the BMSCs which were incubated in Transwell chambers with the density of 2 × 104 cells/cm2 in group B.DRGCs were collected at 48 h of incubation for detection of apoptosis by flow cytometry.Apoptosis rate was calculated.Results Compared with group C,the apoptosis rate was significantly increased in L and B groups (P ＜ 0.05).The apoptosis rate was significantly lower in group B than in group L (P ＜ 0.05).Conclusion BMSCs can reduce lidocaine-induced apoptosis in DRGCs of rats in vitro,indicating that BMSCs may reduce local anesthetics-produced toxicity to the peripheral nerve.

Objective To investigate the role of acid and bile reflux in children with gastroesophageal reflux disease (GERD) and to evaluate the significance of detecting acid and bile reflux in diagnosing GERD in children.Methods Using ambulatory 24 h pH mo-(nitoring) and bilirubin monitoring technique, we simultaneously assessed the changes of intraesophageal pH and bile reflux in 23 subjects (including 11 healthy controls and 12 patients with GERD).Results The time of esophageal acid exposure (pH

Objective To evaluate the safety of surgical procedures for patients after heart valve prosthesis implantation.Methods Clinical data of 12 cases with heart valve prosthesis implantation undergone other surgical treatment from November 1996 to December 2005 were retrospectively analyzed.All the cases had routine oral warfarin with prothrombin time (PT) of 20.0—28.3 s averaged 23.5 s, international normalized ratio (INR) for prothrombin of 1.79—2.23 averaged 1.95 and heart functional class Ⅰ—Ⅲ.Among them,appendectomy was performed in three cases with acute appendicitis,reposition and repair in one with inguinal hernia,radical gastrectomy in two with gastric carcinoma,left hemicolectomy in one,cholecystectomy in three,left femoral head replacement in one,and bilateral high ligation and ablation of great saphenous vein in one.Elective surgical operation was performed in seven cases,and emergency operation in five.In those with elective surgery,warfarin was stopped 2—3 days before operation,while 5—10 mg vitamin K_1 was injected intramuscularly 6—8 hours before emergency surgery with preoperative median PT of 15.1 and 15.3 s and median INR of 1.24 and 1.30,respectively.In operation,5—10 mg vitamin K_1 were injected intravenously into the patients by drip depending on their bleeding on the surface of wound.ECG,blood pressure,hemoglobin and oxygen saturation were routinely monitored for all the cases intraoperatively and postoperatively.For the cases with heart function above class Ⅱ,fluid infusion was adjusted based on intubated central venous pressure,and for those with general anesthesia,analyses of blood gases and electrolyte were monitored routinely in operation.Results OPeration time averaged 20—160 rain in all the 12 patients,with blood loss 5—280 ml in average and without complications of massive hemorrhage,thrombosis and heart failure.Conclusions Surgical operation was safe for patients with heart valve prosthesis implantation,if preoperative PT and INR were adjusted to about 15 s and 1.30,respectively by cessation of warfarin or application of vitamin K_1,combined with careful manipulation and strengthened perioperative management.

Objective: To explore the characteristics of external iliac artery vascular complications atfer renal transplantation and the diagnosis and treatment. Methods: We reviewed the clinical data of 6 patients with of external iliac artery vascular complications atfer renal transplantation from more than 2000 renal transplantation patients in the Transplantation Center of the Third Xiangya Hospital of Central South University from 2001 to 2013, and analyzed the clinical characteristics, diagnosis and treatment. Results: hTe renal allogratf was removed in 5 of the 6 patients due to repeated external iliac arteryhemorrhage: 2 patients were replaced the external iliac artery with reversed autogenous great saphenous vein, 2 patients underwent the bilateral femoral artery bypass surgery, and 1 was repaired the external iliac artery directly. The other 1 was resected the renal allograft and the involved external iliac arteries due to fungal mass in the external iliac artery. Among the 6 patients, except 1 patient died atfer the surgery of the repair of the external iliac artery, the other 5 are all alive. Conclusion: Vascular replacement and artery bypass are effective methods for patients with external iliac artery vascular complications atfer kidney transplantation.
