Objective To study the risk factors affecting neoplasm recurrence and survival of hepatocellular carcinoma(HCC)following liver transplantation(LT).Methods The clinicopatholo gic data,neoplasm recurrence and survival results of 118 patients with HCC receiving LT were retro- spectively analyzed and various clinicopathologic risk factors for neoplasm recurrence and survival were evaluated by univariate and multivariate analysis.Results The follow-up time ranged from 1 to 32 months.The recurrence rate was 37.3% and the mortality was 35.5%.The 12-,18-,24-month survival rate was 84.55%,70.30% and 62.24%,respectively.The 12-,18-,24-month neoplasm free survival rate was 69.05%,66.93% and 61.38%,respectively.In the univariate analysis,por- tal vein neoplasm thrombus(PVTT),Milan-criteria,neoplasm size,histological differentiation and pTNM stage were associated significantly with neoplasm recurrence,and PVTT,Milan-criteria,pre- operative alpha-fetoprotein(AFP),histological differentiation and pTNM stage were associated signif- icantly with survival rate;In the multivariate Logistic regression analysis,PVTT and histological dif- ferentiation were independent predictive factors of neoplasm recurrence,and multivariate Cox regres- sion analysis showed that PVTT and AFP independently associated with prognosis.Conclusions PVTT and histological differentiation are the most important predictive factors of neoplasm recur- rence,and PVTT and AFP independently predict the survival of patients undergoing LT.

Objective To investigate factors influencing islet isolation and purification in dogs and to explore how to obtain massive purified viable islets from canine pancreas.To provide experimental evidence for pancreatic islet transplantation in clinical practice.Methods Islets were isolated from pancreas of 22 dogs by modified automated techniques,followed by purification using continuous density gradients.The purity of islets was determined by dithizone (DTZ) staining,and the function of islets was evaluated by glucose stimulating insulin release test.Results The crude islets yield was ( 155 040 ±310) IEQ/pancreas while the yield was (74 200 ±185) IEQ/pancreas after purification.The average purity was (89.4 ±2.6) ％.The recovery rate was(47.8 ±1.3) ％.Islet viability was(93.0 ± 1.7)％.The modified techniques improved both the yield and the quality in islet isolation and purification.The islets were morphologically intact after purification.Glucose stimulating insulin release test showed that the difference of the secreted insulin concentration had statistical significance ( P ＜0.001 ) between low concentration glucose group and high concentration glucose group.Conclusion It is of great value for clinical research to obtain enough islets through islet isolation and purification in dogs.

OBJECTIVETo investigate the role of perindopril for prevention and treatment of glucocorticoid-induced osteoporosis (GIOP) in rabbits.

METHODSA total of 45 male New Zealand white rabbits (10 months old, weight 3.0 to 3.5 kg) were randomly divided into 3 groups involving normal control group (muscle injection of saline solution, n = 15, group NC), model group (muscle injection of dexamethasone, n = 15, group GIOP), and treatment group (muscle injection of dexamethasone combined with oral perindopril, n = 15, group GIOP+ACEI). All rabbits put to death after 12 weeks' treatment. The changes of bone mass and strength were observed and analyzed by bone histomorphology, biomechanics, metabolic bone related serological indexes and mRNA expression.

RESULTSAt 12 weeks, the analysis of bone histomorphology and biomechanics results showed that the bone mass and bone strength of group GIOP were significantly lower than that of group NC (P < 0.05); after perindopril treatment, the bone mass and bone strength of group GIOP+ACEI were higher obviously than that of group GIOP (P < 0.05). Mineralizing surface,mineral apposition rate and serum osteocalcin in group GIOP decreased than group NC; however, osteoclast number, osteoclast surface, eroded surface, and urinary deoxypyridinoline in group GIOP increased than group NC (P < 0.05); these changes were inhibited after perindopril treatment (P < 0.05). Quantitative RT-PCR revealed that after dexamethasone treatment, the ratio of SOST mRNS expression and RANKL/OPG mRNA expression obviously increased than that of group NC (P < 0.05); and Runx2 expression decreased significantly (P < 0.05); while the changes of mRNA expression were improved by perindopril treatment.

CONCLUSIONPerindopril can promote bone formation and inhibit bone resorption to deduce glucocorticoid-induced osteoporosis. This study provides a new method for prevention and treatment of GIOP.

OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.

METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.

RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).

CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.

"Mistreatment by warming therapy" refers to various symptoms/syndromes caused by improper use of fire methods mentioned in Treatise on Febrile Diseases, which are similar to damaged yin induced fire-heat syndrome (injury of yin, consumption of qi, loss of yin, consumption of body fluid) manifested after radiotherapy and/or chemotherapy in modern clinics. Better efficacy was obtained in treating various symptoms/syndromes by using nourishing yin purging fire method. In this paper authors focuses on exploring guiding significance of using "Mistreatment by warming therapy" in treating non-small cell lung cancer (NSCLC).

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Objective To assess longitudinal segmental myocardial strain and displacement of left ventricle (LV) in patients with dual chamber pacing (DDD) using velocity vector imaging (VVI) and to explore the clinical application value of VVI in assessing left ventricular motion.Methods A total of 23 patients before and after DDD pacemaker implantation were enrolled in this study.The peak systolic strain and displacement of ventricular segments were measured with VVI and compared before and after pacemaker implantation.Results Compared to the values at the baseline,the strain and displacement of lateral,interventricular septum,anterior and posterior wall of LV in patients with pacing were significantly decreased.The strain,displacement of basal and mid segments with pacing were decreased as well(P＜0.01).The left ventricular strain and displacement in patients with pacing were significantly decreased than those of patients at the baseline(P＜0.05).Left ventricular longitudinal displacement before and after DDD pacing was significantly decreased from basal,mid to apical segments.But no significant difference was found in longitudinal strain from basal,mid to apical segments of LV.Conclusions (1) Left ventricular strain and displacement in patients with pacing were different between those before and after DDD pacing.(2) VVI can accurately assess left ventricular strain and displacement in patients with DDD pacing,and can become a powerful mean to assess the regional myocardial function.
