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 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 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.

OBJECTIVETo explore the feasibility of short-term neoadjuvant chemotherapy (NACT) in patients with advanced gastric cancer (AGC), and to compare clinical efficacy of short-term neoadjuvant chemotherapy with different ways.

METHODSClinical data of 310 AGC patients treated with one course of NACT using EOF regimen(epirubicin, oxaliplatin and fluorouracil plus calcium folinate) in our hospital from January 2008 to December 2011 were retrospectively analyzes. Efficacy was compared between regional arterial infusion chemotherapy and intravenously chemotherapy.

RESULTSAll the 310 AGC patients completed one course of NACT and none was interrupted by adverse events. Postoperative pathological remission rate was 33.9% (105/310) and 5 patients (1.6%) had complete pathological remission. The pathologic response rate in the regional arterial infusion chemotherapy group was higher than that in the intravenously chemotherapy group(42.4% vs. 23.6%, P = 0.001). Multivariate analysis revealed that chemotherapy method(HR=1.827, 95% CI:1.006-3.316, P = 0.048) was associated with significantly higher pathologic response.

CONCLUSIONSPathological response rate is quite low following short-term NACT. Regional arterial infusion chemotherapy with short-term NACT can improve the pathological response rate of advanced gastric cancer.
