Medical Journal of Chinese People's Liberation Army 2001;0(08):-
To investigate the monitoring of acute rejection of porcine pancreaticoduodenal allografts, 12 pigs were subjected to pancreaticodudenal allografts, among them 6 pigs received triple therapy for 7 days. Serial biopsies were performed in pancreas allografts for diagnosis of pancreatic acute rejection. Amylase secretion was determined periodically.The levels of TNF ? and NO in serum were serially monitored.The results showed that amylase secretion decreased,TNF ? and NO concentration in serum increased significantly as acute rejection was detected histo pathologically in pancreatic grafts. It suggested that monitoring of amylase secretion, serum TNF ? and NO concentration could be used to decide the proper time of performing biopsy for early diagnosis of acute rejection of the pancreas allograft.

Objective To explore the effect of preoperative radiotherapy on angiogenesis of rectal cancer. Methods Twenty patients with advanced lower rectal carcinoma received preoperative radiation with a dosage of 30~40 Gy each time for a total of 15~20 sessions during a period of 3~4 weeks. The definitive surgery was performed 7~10 days after radiotherapy. Another 20 patients undergoing tumor resection without preoperative radiotherapy served as control. Tumor sample was sent for pathology. The expression of vascular endothelial growth factor (VEGF) and CD34 in the rectal cancer were detected immunohistochemically. The intratumoral microvessel density (MVD) was measured. Results Fifteen patients were found with grade Ⅱ and five patients with grade Ⅲ tissue response in radiotherapy group. The diameter of intratumoral microvessel was smaller in radiotherapy group than in control group( P

Objectives: To investigate the effect of growth hormone on liver protein synthesis in patients with portal hypertension following TIPS. Methods: Ten patients with liver cirrhosis and portal hypertension were injected with rhGH (8 U/day) for 7days after TIPS. The serum levels of Alb, PA and FN were detected before and days 3 and 7 after TIPS and use of rhGH. Plasma insulin like growth factor 1 (IGF 1) was also measured by immunoradiological method. Results: As compared with the day before TIPS and rhGH, the levels of IGF 1, Alb , PA and FN were significantly increased on the 7th day after TIPS and rhGH treatment( P

Objective: To evaluate the effectiveness of bowel nutritional rehabilitation therapy in patients with gut dysfunction caused by acute mesenteric artery occlusion. Methods: Two patients with acute mesenteric artery occlusion received management of revascularization by operative and nonoperative approach. Viability dusky bowel was leaved in one patient. Second look laparotomy was performed to access the viability of the bowel in another patient. The patients remained gut dysfunction and received bowel nutritional rehabilitation therapy early after operation. Results: The gut function of the patients recovered and had normal diet after bowel nutritional rehabilitation therapy. Conclusions: The gut dysfunction caused by acute mesenteric artery occlusion should be treated with bowel nutritional rehabilitation early.

Objective To observe the morphology, quantity and migration of Langerhans cells in normal or HPV-infected skin treated with localized hyperthermia. Methods Tissue specimens obtained from 16 patients with condyloma accuminatum (CA) and 15 normal controls were divided into three equal parts, and irradiated by a self-made hyperthermia equipment at 37℃, 42℃ and 45℃ respectively for 30 minutes. Immunohistochemistry and flow cytometry were applied to detect the morphology, quantity and migration of Langerhans cells (LCs), respectively, in these treated specimens. Results With a rise in temperature, the number of LCs in epidermis decreased, the dendrites shortened, decreased in number or even disappeared. After exposure to hyperthermia at 37℃, 42℃ and 45℃, the number of LCs was 782.40±114.8, 649.44±119.40 and 510.88±118.64 per square millimeter respectively, in normal tissue, 646.04±135.67, 489.38±118.19 and 387.93±110.15 per square millimeter respectively in HPV-infected skin tissue.The percentage of migratory LCs expressing CD1a was 0.19%±0.18%, 0.89%±0.19% and 1.59%±0.28% in normal skin tissue treated with hyperthermia at 37℃, 42℃ and 45℃ respectively, 0.62%±0.31%,2.31%±0.54% and 6.33%±0.98%, respectively, in HPV-infected skin tissue; the differences were significant among these different temperatures. Furthermore, the migration of LCs from tissue into culture was enhanced by the treatment with hyperthermia. Conclusions Hyperthermia can promote the migration of LCs, and accordingly enhance the antigen presenting effect of these cells in immune response.

Objective To detect the expression of GHR in colorectal cancer cell lines and determine whether recombinant human growth hormone can promote the proliferation of colorectal cancer cells in vitro.Methods GHR distribution was assessed by flow cytometry and immunofluorescence method in 9 colorectal cancer cell lines.The effect of recombinant human growth factor on colorectal cancer cell line proliferation was assessed by MTT method.Results Different GHR expression was determinated in 9 colorectal caner cell lines.GHR was highly expressed in HCT-8 while GHR expression could hardly be detected in LoVo.r-hGH could promote GHR(+) HCT-8 cell proliferation at 50 ng/ml and 100 ng/ml (P <0.05).But this effect was not dose dependent.When the neutralizing antibody was used to block GHR activity,this r-hGH dependent proliferation effect was eliminated.r-hGH could not promote GHR (-) LoVo cell proliferation (P >0.05).Conclusion The results demonstrates that r-hGH could promote GHR (+) tumor cell proliferation and this effect is mediated by GHR.The use of r-hGH on the colorectal cancer patients should be cautious.

Objective:To investigate the correlation between the iliac cortical density line and pelvic tilt (PT) in X-ray films of patients with kyphosis.Methods:The imaging data of 67 patients with kyphosis treated in Tianjin Beichen Hopsital from August 2016 to December 2019 were analyzed retrospectively. PT and iliac tilt (IT) were measured on lateral X-ray of the spine. IT was defined as the angle between the density line of the iliac cortex and vertical direction. The correlation between PT and IT was analyzed, and a linear regression model was established.Results:PT and IT can be determined by X-ray lateral films of spine in 67 patients. Pearson correlation analysis results showed that PT was significantly correlated with IT( r=0.852, P<0.05). Subgroups analysis was conducted by gender. The linear regression formulas for females and males were PT=IT-12.9° and PT=IT-16.7°, respectively. Conclusions:When it is difficult to identify the femoral head on X-ray film, IT can be measured conveniently and directly through the density line of the iliac cortex, and then PT can be reliably evaluated through IT.

Objective: To observe the effect of nutritional support and metabolic intervention in a patient receiving combined liver and intestinal transplantation. Methods: Glycyl glutamine(Gly Gln)and arginine supplemented total parenteral nutrition(TPN) was administered since postoperative day(POD)1. Glutamine(Gln) and arginine supplemented enteral nutrition(EN) was applied since POD 4. Growth hormone(GH) was delivered intermittently since POD 4.With adaptation and tolerance, enteral feeding was progressively increased while parenteral nutrition reciprocally decreased. Results: Transplanted organs functioned well. Conclusions: Rehabilitation of the allograft function can profit from the application of nutritional support and metabolic intervention.
