Chinese Journal of Hepatic Surgery(Electronic Edition) 2024;13(4):481-
Pancreatic neuroendocrine neoplasms (pNENs) is a category of highly heterogeneous tumors. Surgery is the only treatment option that offers the potential to cure pNENs. Neoadjuvant therapy enables patients with locally advanced pNENs or liver metastases to obtain the chance of reoperation. Neoadjuvant therapies for pNENs mainly include chemotherapy, targeted therapy, somatostatin analogues, and peptide receptor-radionuclide therapy, etc. CAPTEM regimen and platinum-based chemotherapy regimen are commonly used in chemotherapy. Somatostatin analogues and peptide receptor-radionuclide therapy are primarily given for individuals with high expression of somatostatin receptor. Targeted therapy is mainly delivered for locally advanced well-differentiated pNENs. These regimens can be adopted alone or combined to enhance clinical efficacy. At present, high-level evidence-based medicine evidence is lacking in the selection of treatment regimens, and systematic evaluation is also lacking in comparison of the clinical efficacy among different protocols.

Pancreatic cancer is a highly malignancy of the digestive system, with low early diagnosis rate and poor prognosis. Cancer cachexia, muscle and adipose tissue wasting are important factors affecting surgical complications and long-term prognosis of patients with pancreatic cancer. On one hand, the occurrence and development of pancreatic cancer cachexia are associated with the decrease of food intake. On the other hand, the characteristic of tumor hypermetabolism, many inflammatory factors, fat and protein regulatory factors and many neuroendocrine pathways are also involved in pancreatic cancer cachexia. At present, the understanding of cancer cachexia and tissue wasting is not comprehensive, and the diagnostic methods are not unified. The main screening method is based on body mass index, but it is not applicable to obese patients. The detection of serum cytokines and determination of intramuscular fat content based on the abdominal computed tomography scan also play pivotal roles in the diagnosis of pancreatic cancer cachexia. Perioperative inhibition of tissue wasting can not only reduce surgical complications, but also improve the prognosis of pancreatic cancer patients. However, there is no effective method to completely reverse cancer cachexia. Multidisciplinary treatment is the routine therapy. Surgical treatment to remove the tumor is the fundamental measure to impede the development of cachexia. In addition, strengthening nutritional support, reducing inflammation and stress reaction, reducing the muscle wasting are also important in the treatment of cachexia during the perioperative period. Combined with self experience, the authors comprehensively analyze research advances, summarize the etiology, molecular mechanism, diagnosis and treatment of tissue wasting, in order to investigate tissue wasting and perioperative treatment strategies of pancreatic cancer patients.

AIM: Metallothioneins (MTs) are cysteine-rich metal-binding proteins that exert cytoprotection during metal exposure and oxidative stress. The present study was designed to investigate whether MT can directly protect NTPase on nuclear envelope from damage induced by hydroxyl radical.METHODS: Isolated hepatic nuclei from rat liver were exposed to Fe 2+ /H 2O 2 with or without MT, and the NTPase activity on nuclei was assayed using ATP and GTP as substrate, respectively. RESULTS: Incubation of rat hepatic nuclei with the Fe 2+ /H 2O 2 (in ?mol?L -1 / ?mol?L -1 : 0 1/0 5, 0 5/2 5, 1/5, 5/25) resulted in a concentration-dependent decrease in nuclear NTPase activities ( P0 05 ). In addition, incubation of hepatic nuclei with only MT had no effect on nuclear NTPase activity. CONCLUSION: These data demonstrate that hydroxyl radical generated from Fe 2+ /H 2O 2 might attack nuclear NTPase. MT antagonistically reduces toxicity of Fe 2+ /H 2O 2 system to the NTPase.

Objective To analyze the patterns of amino acid changes in liver failure patients treated with non-bioartificial liver support system (ALSS), and to explore the efficacy of ALSS in liver failure treatment. Methods A total of 146 liver failure patients treated with ALSS from June 2009 to August 2010 were recruited in this study. Paired blood samples were collected from every patient and serum amino acids and ammonia were tested by automatic amino acid analyzer. The changes of amino acids in patients with different prognoses, different types/phases of liver failure were evaluated.Measurement data were compared by paired t test. Results After ALSS treatment, liver failure patients experienced a significant decrease in serum glutamic acid and lysine [(395.62±200.24)μmol/Lvs (260. 05±169.56) μmol/L and (436. 73±326. 18)μmol/L vs (407. 12±292.01) μmol/L,respectively; t= 8. 611 and 2. 659, respectively; both P<0.01)], while experienced greatly increases in threonine and branched-chain amino acids/aromatic amino acid ratio [( 1302. 90 ±1288.70) μmol/L vs (1406.70 ±1272. 34) μmol/L and 1. 23 ± 0. 53 vs 1. 36 ± 0.57, respectively; t = 2. 895 and 1. 061,respectively; both P<0. 01)]. The changes of glutamic acid, tyrosine, arginine and methionine before and after ALSS treatment in patients with different prognoses, different types/phases of liver failure were all significantly different. Conclusions ALSS treatment could improve the serum amino acid disorder in liver failure patients. The amino acids in patients with different types/phases or different prognoses of liver failure change significantly after ALSS treatment.

Objective To explore the value of combined detection with MMP-9 and uPA in the progno-sis of pancreatic carcinoma. Methods By immunohistochemistry PV methods,the expression of MMP-9 and uPA was respectively studied in 63 surgical specimens of primary pancreatic carcinoma and the survival time of patients with pancreatic carcinoma was analysed. Results The expressions of MMP-9 and uPA were positively related(r=0. 573,P=0. 000). The expression of MMP-9 and uPA significantly correlated with differentiation (r= -0. 271,P=0. 032;r= -0. 333,P=0. 008),TNM stages(r= -0. 449,P=0. 000;r= -0. 430,P=0. 000)and lymph node metastasis(r=0. 329,P=0. 009;r=0. 400,P=0. 001),separately. The expression of MMP-9 had also a significant correlation with tumer size(r= -0. 297,P=0. 018)and distant metastasis(r=0. 320,P=0. 011). Univariate analysis identified that tumor size(χ2 =8. 766,P=0. 012),differentiation(χ2 =29. 050,P=0. 000),clinical stage(χ2 =24. 940,P=0. 000),distant metastasis(χ2 =12. 846,P=0. 000), lymph node metastasis(χ2 =15. 457,P=0. 000),MMP-9(χ2 =32. 700,P=0. 000)and uPA(χ2 =41. 495,P=0. 000)were significantly associated with prognosis. Kaplan-Meier survival analysis showed that 1-year survival rate of patients with MMP-9 ( -),uPA ( -)were significantly longer than that of the patients with MMP-9( ﹢),uPA( ﹢),respectively(χ2 =32. 700,P=0. 000;χ2 =41. 495,P=0. 000);1-year survival rate of patients with MMP-9( -)/uPA( -)was significantly longer than the others( Log-rank test,χ2 = 54. 892, P=0. 000). COX regression revealed that differentiation(RR=2. 315,P=0. 004),clinical stage(RR=1. 694, P=0. 002),MMP-9(RR=0. 165,P=0. 000)and uPA(RR=0. 244,P=0. 007)was independent prognostic factors in pancreatic carcinoma. Conclusion They may have a synergistic function in the the process of growth and invasion in pancreatic cancer between MMP-9 and uPA,and the posssible mechanism is that uPA activate degradation of MMP-9,which is not favorable to prognosis. Combined analysis of MMP-9 and uPA may lead to a more reliable prognostic estimation,as the beneficial supplement of the differentiation,and clinical stage to judge the prognosis of pancreatic cancer.
