ABSTRACT
Objective To explore the safety and feasibility of improved jejunostomy in operation for patients with esophageal carcinoma.Methods All these 214 patients underwent resections of esophageal carcinoma and jejunostomy were divided into 2 groups,130 patients in routine group and 84 patients in improved group.A 1.5 to 2.0 centimeter in width pedicled omentum were left during dissociating the stomach for patients of improved group.Double purse-string suture were left on the prepared jejunostomy.Pedicled omentum was placed around jejunum tube which was fixed by double suture to peritoneum.Then the operating time,discharging time,leakage,infections,tube shedding and intestinal obstruction were analysed.Results All patients in both groups were healed.There's a statistically significant difference(P0.05)in discharging time,leakage,infections and tube shedding.Conclusion Improved jejunostomy can reduce the operating time,and it's a safe and feasible way in jejunum tube placement.
ABSTRACT
To investigate the effect of TGF-β1 on the expressions of IL-12, IL-15, IL-18, IL-4 and IL-10 in heart transplantation rejection in rats, a model of rat cervical heterotopic heart transplanta-tion was set up and the model rats were randomly divided into three groups: control group, transplant group and TGF-β1 group. The mRNA expression levels of IL-12, IL-15, IL-18, IL-4 and IL-10 were determined by RT-PCR at the 5th day after the transplantation. The mRNA expression levels of IL-12,IL-15, IL-18 were increased obviously and those of IL-4, IL-10 were significantly decreased in the transplant group as compared with the control group (P<0.01). In the TGF-β1 group, the mRNA ex-pression levels of IL-12, IL-15, IL-18 were significantly decreased and those of IL-4, IL-10 were sig-nificantly increased as compared with the transplant group (P<0.01). The immunosuppressive effect of TGF-β1 on heart transplantation rejection was related to its inhibition of the expressions of Th1-type cytokines (IL-12, IL-15, IL-18 etc) and its promotion of the expressions of Th2-tpye cyto-kines (IL-4, IL-10).
ABSTRACT
Objective To put forward a design of the software of brainwave therapeutic apparatus based on the MCU. Methods Based on principle of electroencephalogram music treatment, several sound synthesis techniques were analyzed and contrasted. A simple and easily-realized one was selected and analyzed in detail. Finally, the output of brainwave therapeutic apparatus was tested and errors were analyzed. Results The selected scheme can effectively generate brainwave music. Conclusion According to the scheme, a low-cost and reliable brainwave therapeutic apparatus can be made by using the MCU.
ABSTRACT
By means of radioimmunoassay, leucine-enkephalin (L-ENK) in the uteri of women and rats was studied and its responses to ovarian steroids were observed. The histological localization of L-ENK and the influence of naloxone (NAL) on estrogen regulation of the rat uterus in terms of cAMP and eGMP determination were also studied. Results of the study demonstrated that presence of L-ENK like substance in the uteri of women and rats, and the concentrations varied in the various phases of the sexual cycle. indicating a positive correlation with levels of estrogen in the body. L-ENK was found localized in the interstetial cells of the human endometrium, and in the rat uterus. Effect of extrogen on nucleotide was influenced by NAL. The findings suggested that L-ENK may play an important role on physiologic function of utetus.
