【Abstract】Objective The injury induced by hepatic artery ischemia (HAI) in the liver transplantation procedure and the protective effects of using hepatic artery bridge-conduit (HABC) technique were studied. Methods Thirtytwo dogs were randomly divided into 4 groups: control, HAI 30 min, HAI 2 h and HABC groups. We observed the pathological changes of hepatocytes and biliary tract tissues and the microstructure of chondriosome, which were based on the model of auto-orthotopic liver transplantation in dogs. Biochemical and spectrophotometric methodswere used to evaluate the content of MDA and SOD, SDH activities in the graft liver tissue respectively. Results The pathologic and electrical microscopic changes of hepatocytes and epithelial cells of bile ducts were found in HAI 30 min and HAI 2 h groups,while the content of MDA increased to （1.652±0.222） nmol/mg prot and (2.379±0.526) nmol/mg prot, and SOD activity decreased to (11.15±3.9) U/mg prot and (9.47±3.4) U/mg prot. At the same time, SDH activity was also down-regulated to 0.362±0.019 and 0.281±0.029. Compared with control group, the differences were significant (Plt;0.05, Plt;0.01). But these changes of functional index caused by HAI injury were not significant in HABC group. Conclusion The HABC technique can not only avoid HAI injury during operation but also alleviate the occurrence of complication after transplantation, especially the biliary tract complication.
Objective To introduce the technique of esophageal intraluminal stenting and assess its effect on the prevention of development of stenosis in patients with esophageal burns. Methods Thirty-three patients were admitted less than 3 weeks after ingestion of caustic agents. The second-or third-degree injuries were confirmed by esophogoscopy in all cases, but one with esophageal perforation at admission. Esophageal stenting was performed in all patients and these stents were kept in place for 4 to 6 months. Results There was no death in the series. All patients had a normal intake of food after removal of the stents, and stricture was not found on barium swallow test. Follow-up from 1 to 60 months five cases developed esophageal stenosis from 2 to 3 months after extracting the stents. One of them responded to esophageal bougienage, the remaining 4 patients required esophageal reconstruction and took a normal diet postoperatively. The other 28 patients have a normal diet after the stent removal. Conclusion The esophageal intraluminal stenting is able to prevent the formation of stricture in the aftermath of esophageal burns and its effect will be enhanced plus administering isoniazid.
To report a case of a 1-year-old female child admitted to the hospital with recurrent convulsions and diagnosed as West syndrome, also known as infantile spasms (IS). The child had been experiencing convulsions for 4 months prior to admission, characterized by forward head tilt and flexion of the limbs, with 8 ~ 10 episodes per day. After admission, West syndrome was identified by EEG and imaging evaluation, and adrenocorticotropic hormone (ACTH) shock therapy was started on day 5 of admission, supplemented with peripherally inserted central catheter (PICC), gastric protection, calcium and potassium supplementation and other supportive measures. During the course of treatment, the nursing team implemented meticulous monitoring and assessment to ensure that the child's vital signs were stabilized, and potential side effects were detected and treated in a timely manner. After 14 days of treatment, the child had no further spasticity episodes during 3 ~ 14 days, and was discharged from the hospital with continued oral hormone intake and regular follow-up. During the nursing process, the nursing staff provided psychological support and education to the child and her family to help the family understand the disease and enhance their ability to manage it. In addition, personalized nutritional support and monitoring were provided to ensure the healthy growth of the child. The successful management of this case not only enhanced the quality of clinical care, but also provided useful reference and inspiration for similar cases.

ObjectiveTo analyze therapeutic effect of ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage in treatment of granulomatous mastitis (GM).MethodsThe clinical data of 120 patients with GM from January 2018 to December 2018 in the Renmin Hospital of Wuhan University were analyzed. Sixty patients were treated with the ultrasound-guided vacuum-assisted rotary excision with tube irrigation drainage (control group), and the other 60 patients were treated with the metronidazole solution combined with dexamethasone on the basis of the control group (observation group). The therapeutic period, total effective rate, postoperative appearance of breast, and recurrence rate were analyzed. While the pathogenic bacteria was analyzed by the microbial culture and the pathogen gene detection.ResultsThere were no significant differences in the baseline data between the two groups (P>0.05). The ultrasound-guided vacuum-assisted rotary excisions were successfully performed in all 120 patients. The therapeutic period of the observation group was shorter than that of the control group (t=–3.633, P<0.001). The total effective rate and rate of excellent and good of postoperative breast appearance had no significant differences between the two groups (total effective rate: 96.7% versus 90.0%, χ2=1.922, P=0.166; rate of excellent and good of postoperative breast appearance: 96.7% versus 88.3%, χ2=1.205, P=0.272). The recurrence rate of the observation group was lower than that of the control group (χ2=5.175, P=0.023). The positive rates of bacteria were 25.8% and 58.8% in the 120 cases by the microbial culture and 52 cases by the pathogen gene detection, respectively, which had a statistical difference (χ2=16.974, P<0.001), the same conclusions were obtained in the observation group and the control group (χ2=6.691, P=0.010; χ2=9.379, P=0.002).ConclusionsUltrasound-guided vacuum-assisted rotary excision with tube irrigation drainage is well applied in treatment of GM. It could maintain a good shape of breast. Use of metronidazole solution combined with dexamethasone after surgery could shorten therapeutic period and reduce recurrence rate.

According to the follow-up results, the authors recommend that the internal drainage through PTCD is the better method to treat unresectable carcinoma of bile duct for proper patients.
Objective To investigate the safety and effectiveness of the operation of integrate subparagraph, fenestration, exclusion, cut expansion, seton, tube, and drainage (ISFECSTD) to cure complex anal fistula. Methods Using randomized comparison and multicenter parallel experiment, the total number was 240: 120 patients in study group treated by ISFECSTD, and 120 patients in control group treated by extended cutting and seton operation. Then compared the safety and effectiveness between two groups. Results The clinical recovery rate of the study group was significantly higher than that in the control group （Plt;0.05）. The operation time and wound healing time in study group were significantly less than those in control group, and the scar area after wound healing was smaller than that in control group （Plt;0.01）. The decreased extents of anorectal pressures and rectal capacity feeling function after operation in study group were smaller than those in control group (Plt;0.01). Rectal and anal reflex function and healing of the endostoma, stem, and branch in study group were better than those in control group (Plt;0.05, Plt;0.01). Incidence of anal incontinence after operation in study group was significantly less than that in of anus-rectum structure and function, and has the merits of higher cure rate, shorter time of healing, smaller scar, less pain, etc. The method of ISFECSTD is worth being a new standardized operation in the clinical application.
