H-tensors have wide applications in science and engineering, but it is difficult to determine whether a given tensor is an H-tensor or not in practice. Several new iterative judging criteria were given for H-tensors through construction of different positive diagonal matrices and introduction of some techniques of inequalities. For application, some sufficient conditions of the positive definiteness for an evenorder real symmetric tensor were given. Results of the numerical examples illustrate the effectiveness of the presented criteria. [ABSTRACT FROM AUTHOR]

Objective To evaluate the clinical efficacy of total pancreatectomy-islet autotransplantation (TP-IAT) in the treatment of chronic pancreatitis. Methods One patient diagnosed with refractory chronic pancreatitis complicated with multiple pseudocysts and pancreatic stones underwent TP-IAT in the First People's Hospital of Foshan. Clinical data were collected and analyzed during postoperative 3 months follow-up. Results The patient was well recovered after TPIAT without complications, such as bleeding and severe hypoglycemia. Abdominal pain was completely relieved without taking analgesic drugs. During postoperative follow-up, the patient was treated with exogenous insulin, the fasting blood glucose was properly controlled and the function of islet cells was partially restored. Conclusions TP-IAT can not only relieve the clinical symptoms of chronic pancreatitis, but also prevent postoperative diabetes mellitus, which is an efficacious treatment of refractory chronic pancreatitis.

Objective To summarize the feasibility and safety of fast perfusion through abdominal aorta and portal vein in combined liver and kidney procurement from organ donation. Methods Clinical data of 43 donors of donation after cardiac death (DCD) undergoing combined liver and kidney procurement in the First People's Hospital of Foshan from September 2011 to June 2014 were analyzed retrospectively. Among the 43 donors, 15 cases were China DCD donor category I(donor after brain death)(C-I), 1 case was category II (donor after cardiac death)(C-II) and 27 cases were category III (C-III). Combined abdominal aorta and portal vein perfusion with fast cannulation were performed. Results The time from abdomen incision to abdominal aorta cannulation was 1.5-2.0 min. Forty-three livers and eighty-six kidneys were procured from 43 donors. The warm ischemia time (WIT) was 0 for C-I donors, and was 3-21 min for the other donors (mean:10 min). Two liver grafts were discarded for major injury of the porta hepatis and severe fatty liver respectively. Eighteen kidney grafts were discarded for kidney stones, kidney atrophy, high level of preoperative serum creatinine, severe renal atherosclerosis, renal microvessel thrombosis, multiple renal cyst, kidney traumatic rupture, etc. The total discard rate of donor organs was 16%. Conclusions Fast perfusion through abdominal aorta and portal vein is a simple and safe method in combined procurement liver and kidney from organ donation. [ABSTRACT FROM AUTHOR]

Objective To explore the short-term clinical efficacy and safety after liver transplantation with organs from Chinese donation after citizens' death in patients with high model for end-stage liver disease (MELD) score. Methods The clinical data of 34 liver transplantation recipients with organs from donation after citizens' death from November 2011 to June 2014 in the First People’s Hospital of Foshan were retrospectively analyzed. All recipients were divided into the high MELD score (MELD score≥25, n = 8) and low MELD score groups (MELD score < 25, n = 26) according to preoperative MELD score. Preoperative, intraoperative and postoperative status of the patients was statistically compared between two groups. Results Prior to operation, the proportion of patients requiring artificial liver support and the incidence of acute or chronic and acute liver failure in the high MELD score group were significantly higher than those in the low MELD score group (all in P < 0. 05). Intraoperatively, there was no significant difference in blood loss, perfusion volume,warm and cold ischemia time, anhepatic period,operative time and approach between two groups (all in P > 0. 05). After operation, the length of intensive care unit (ICU) stay in the high MELD scoregroup was significantly longer than that in the low MELD score group (P < 0. 05). And there was no significant difference in the length of hospital stay, mortality during hospitalization, incidence of early complications, follow-up time and overall survival rate between two groups (all in P > 0. 05). The peak level of aspartate aminotransferase (AST) in the high MELD score group was significantly higher compared with that in the low MELD score group (P < 0. 05). The incidence of bile leakage, abdominal abscess and liver dysfunction significantly differed between two groups (all in P < 0. 05). Conclusions It is a safe and short-term efficacious approach to perform liver transplantation with organs obtained from Chinese donation after citizens' death in patients with high MELD score liver recipients.
