ABSTRACT

Objective@#The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors.@*Methods@#We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model.@*Results@#The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage Ⅰ, Ⅱ, ⅢA, ⅢB and Ⅵ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all).@*Conclusions@#The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.

ABSTRACT

The classification and treatment patterns of adenocarcinoma of esophagogastric junction (AEG)do not comply with the"gold standard"for its unique anatomical location and biological characteristics. With an increasing incidence rate of AEG in recent years, the importance of AEG in public health has caught much attention. Surgery is considered as the first choice for the treatment of AEG, but surgical treatments for different types of AEG is still controversial. Many clinical trials have proved the adjuvant therapy and neoadjuvant therapy are beneficial to the improvement of surgical resection and survival rate. Molecular targeted drugs might bring light for the treatment of advanced AEG. Individual therapy of AEG has become increasingly important with the development of science and technology and the results of large clinical researches published. This article reviews the latest progress of surgery-prioritized multimodality therapy for AEG.

ABSTRACT

Hepatolenticular degeneration was one of the rare several genetic metabolic diseases in clinic that could be cured by liver transplantation method, developing slowly and being irreversible. Metabolic disorders of copper lead to abnormal copper accumulation in various of tissues and organs. So that, the disease′s clinical manifestations were lacking in specificity and many patients missed the best opportunity of drug treatment. With the maturity of technologies and innovation of theory of liver transplantation, there were more and more methods that will be applied to personalized treatment. In this paper, a review of the research progress in the treatment of hepatolenticular degeneration with liver transplantation was made with reference to the relevant literature at home and abroad.

ABSTRACT

AIM:To investigate the role of B cells in CD45RB antibody-induced transplantation immune toler-ance.METHODS:Single cell suspension was made from the spleen of BALB/c nude mice disposed by CD45RB antibod-y, then mixed cultured with T cells of BALB/c mice and spleen cells of C57BL/6 mice.The Th1, Th2, Treg and Tm cells were monitored by flow cytometry during the culture process .The skin graft model was set up with B 6.μMT-/-mice as re-ceptors and BALB/c mice as donors.CD45RB antibody was intraperitoneally injected into the receptors after transplantation and then CD3+CD45RBhi cells were detected by flow cytometry .In another mixed lymphocyte culture , CD45RB antibody was added, and then B cells were isolated and injected into B6.μMT-/-mice through the tail vein.The heart transplanta-tion model was established with B 6.μMT-/-mice as receptors and BALB/c mice as donors, and then the survival and the migration of B cells to the thymus were observed .RESULTS:When T lymphocytes were co-cultured with B lymphocytes treated with anti-CD45RB monoclonal antibody (mAb) in vivo, the percentages of Th2 and Treg cells were up-regulated and Th1 cells were down-regulated, but Tm cells were not altered as compared with the control .In vivo without B lympho-cytes, anti-CD45RB mAb also down-regulated the expression of CD45RB in T lymphocytes.The reduction was faster and the percentage of CD3 +CD45RBhi T cells was not altered as compared with the control .The B lymphocytes treated with an-ti-CD45RB mAb in vitro prolonged the lifetime of receptor in heart transplantation model but failed to induce complete toler -ance.After recieving B cells treated with anti-CD45RB mAb and allogeneic heart transplantation , B cells migrated to the thymus in B6.μMT-/-mice.CONCLUSION:B lymphocytes play a definite role in the transplantation immune tolerance induced by anti-CD45RB mAb through their affection on T-cell subgroups and also in the central tolerance .However, the induction of immune tolerance can not only rely on B cells .

ABSTRACT

[Objective] To investigate the clinical characteristics and risk factors of lower-extremity arterial disease in the patients with newly diagnosed type 2 diabetes mellitus combined with nonalcoholic fatty liver disease (NAFLD). [Methods] One hundred fifty-one patients were investigated respectively. The patients were divided into two groups (NAFLD-Group and non-NAFLD group) by liver ultrasonography and disease history, then their clinical data were collected and compared in order to find the differences of biochemical indicators and the morbidity of lower-extremity arterial disease between two groups. [Results] Ninety-two cases (60.93%) were complicated with NAFLD. NAFLD group had higher levels of fast insulin and C peptide level, postprandial insulin and C peptide level, uric acid, body mass index (BMI), homeostasis model assessment (HOMA-IR) and lower level of high-density lipoprotein cholesterol and insulin sensitive index than those of without NAFLD (P<0.05). One hundred and one cases(66.89%) were complicated with lower-extremity arterial disease. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group (75% vs. 54.24%, P<0.01). [Conclusion] Both lower-extremity arterial disease and NAFLD are common complicated with type 2 diabetes. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group.

ABSTRACT

Objective To study the effects of sulodexide on islet B-cell function in streptozocin induced di-abetic rats. Methods Sprague-Dawley(SD) rats were randomly divided into normal control group (group C), dia-betic group without treatment(group D), and suledexide treatment group(group S), a single dose of streptozotocin were abdominally injected to establish the diabetic rat models. Each animal in sulodexide treated group was addition-ally fed with sulodexide of 10 mg/(kg·d) for 12 weeks,while the remained group (group C and D) were given normal water in the same period. After 12 weeks of treatment, fasting plasma glucose(FPG),fasting plasma insulin (FINS), activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), triglyceride (TG), Low-density lipoprotein cholesterol (LDL-C), serum creatinine rates (SCr) and alanine aminotransferase (ALT) were measured. Insulin sensitivity index(ISI) and insulin resistant index (HOMA-IR) were calculated. Results After 12 weeks, the levels of TG, LDL-C and ALT had no significant difference between group D and group S, but were higher than those in group C (P <0.05);There were no significant difference of SCr levels among the three groups. Compared with the group C, APTT, PT, TT and ISI in group D and S were significantly decreased, HOMA-IR were significantly increased (P < 0.05). APTT, PT, TT and ISI in group S had significantly increased compared with that in group D, HOMA-IR was significantly decreased in group S compared with that in group D (P < 0.01). Conclusions Sulodexide can reduce insulin resistant, improve hypercoagulability and insulin sensitiv-ity in streptozocin induced diabetic rats. The effects to blood lipid, liver and renal functions in diabetic rats are not obvious.

ABSTRACT

Objective To compare the excursion of blood glucose (BG) in the type 2 diabetes mellitus treated with oral antidiabetic drugs (OADs) plus glargine or human isophane insulin (HII). Methods A 1 : 1 randomization schedule assigned 30 type 2 diabetics inadequately controlled on OADs (fasting BG>9.0 mmol/L and HbA1C > 8.5%) to 2 groups additionally treated with glargine or HII. The insulin dose was titrated to achieve fasting capillary BG<6.0 mmol/L. Montoring BG with continuous glucose monitoring system, then the standard deviation of BG (SDBG), maximal excursion of BG (LAGE) and coefficient of variation (CV) of fasting plasma glucose (FPG) were calculated. Results SDBG (1.49±0.35 vs 1.73±0.46), LAGE (3.23±0.76 vs 3.73± 1.00) and CV-FPG (17.26±2.24 vs 20.33±3.21) were lower in glargine group than those in HII group (P< 0.05). No difference could be found in hypoglycaemia between two groups. Conclusion OADs plus glargine could make blood glucose more stable than OADs plus HII without increasing the incidence of hypoglycaemia.
