Objective To study the classification, its incidence and some related factors of neurological complications after liver transplantation.Methods 166 cases of orthotopic liver transplantation were retrospectively studied. The classification and the incidence of the neurological complications were analyzed. In addition, the patients were divided into two groups, according to whether they suffered from neurological complications or not, to study the difference of related factors, which included gender, age, primary disease, type of operation procedure, operation time, non-hepatic time, ischemia time of donor liver, blood loss, blood infusion and immunosuppressive regimen.Results Neurological complications occurred in 28 cases (32 times), which included encephalopathy, seizure, stroke, infection of central nervous system, serious para-pyramidal syndrome and peripheral neuropathy. The total incidence was 16.9 %. Between the neurological complication group and non-neurological-complication group, no difference was found in gender, age, type of operation procedure, operation time, non-hepatic time, ischemia time of donor liver, blood loss, blood infusion and immunosuppressive regimen, but the neurological complications were closely related with primary diseases. The incidence of neurological complications was 30 % in acute liver failure, followed by post-hepatitis B liver cirrhosis (21 %), primary liver carcinoma (17.8 %), Wilson disease (16.7 %) and primary biliary liver cirrhosis (12.5 %). Interestingly as a sole complication disease, the incidence of encephalopathy in acute liver failure was 15 %, that was much higher than that in other primary disease. So was the peripheral neuropathy, which was 10 % in primary liver carcinoma.Conclusions The neurological complication is a kind of serious disease with high incidence after liver transplantation. Its onset may have some relationships with the primary liver disease.

Background: The quality of life has been greatly influenced and the cost of medical expenses is very high in patients with irritable bowel syndrome (IBS). The etiology and pathogenesis of IBS are still unclear, and the prevention and treatment of this disease still lack of effective methods. Objective: To explore and analyze the effects of Tiaohe Ganpi Hexin Decoction (TGHD), a compound traditional Chinese herbal medicine for regulating the liver and spleen, on IBS patients with diarrhea. Design, setting, participants and interventions: All 40 IBS patients came from the First Hospital of Jinan University, Guangzhou Red Cross Hospital, and the First Affiliated Hospital of Guangzhou University of Chinese Medicine, and were randomly divided into two groups. Patients in the treatment group (n=20) were given TGHD, while those in the control group (n=20) were prescribed oral pinaverium with a four-week treatment period. Main outcome measures: Traditional Chinese medicine (TCM) syndrome score, total obviously effective rate, disappearance rate of symptoms, and clinical symptom score in the two groups were evaluated before and after four-week treatment. Results: After the treatment, TCM syndrome scores in both groups were decreased (P<0.01), and the TCM syndrome score in the treatment group was significantly lower than that in the control group (P<0.01). There was a significant difference in the total obviously effective rate between the two groups (P<0.01), and the total obviously effective rates in the treatment and control groups were 85%(17/20) and 45%(9/20) respectively. The disappearance rates of abdominal pain, abdominal distention, poor stool output, stool frequency, stool character and mucous stool in the treatment group were higher than those in the control group (P<0.05). The symptom scores of abdominal pain, abdominal distention, poor stool output, stool frequency, stool character and mucous stool in the treatment group were lower than those in the control group (P<0.05). Conclusion: TGHD can significantly improve the clinical symptoms in IBS patients with diarrhea.

Objective To investigate the effect of pregnancy on the potency of bupivacaine for spinal anesthesia in rats. Methods Female non-pregnant SD rats weighing 180-220 g and 17 day pregnant SD rats weighing 350-400 g were used in this study. The rats ( 18 non-pregnant, 18 pregnant) in which PE-10 catheter were successfully placed without complications were selected. The 18 non-pregnant rats were randomly divided into 3 groups (n =6 each): control group (group C), 2% bupivacaine group (group B2 ) and 4% bupivacaine group (group B4). The 18 pregnant rats were also randomly divided into 3 groups (n = 6 each): control group (group PC),2% bupivacaine group (group PB2 ) and 4% bupivacaine group (group PB4 ). Group C and PC received intrathecal (IT) normal saline 30 μl, and the other 4 groups received 2% or 4% bupivacaine 30 μl intrathecally. Analgesia was determined using the taifllick latency (TFL) before IT administration (baseline), and at 10 min, 20 min,30 min, 1 h, 2 h, 4 h, 1 d, 2 d, 3 d and 4 d after IT administtation. The percentage of the maximal possible effect (MPE) was calculated. Hind-limb motor function (MF) was also assessed. Results Compared with the baseline value, MPE at 10 min-2 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B2, MPE at 10 min-4 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B4;MPE at 10 min-1 d after administration and MF scores at 10 min2 h were significantly increased in group PB2 and MPE at 10 min-1 d after administration and MF scores at 10 min4 h were significantly increased in group PB4 ( P < 0.05 ). Conclusion Pregnancy can enhance the potency of bupivacaine for spinal anesthesia in rats.

Objective To establish a new model of acute hepatic failure in canines for bioartificial liver treatment research . Methods Acute hepatic failure was induced by end to side portocaval shunt combined with common bile duct ligation and transection. The survival rate, liver function, ammonia, Fischer's ratio (BCAA/AAA) and pathological change of injury liver were investigated. Results The ammonia, ALT, AKP, total bilirubin and PT were elevated dramatically and Fischer's ratio declined significantly 14 days after the operation. The survival rate of the models decreased with time 14 days after the operation. Pathological examination of liver tissues revealed evidence of cholestasis, inflammation with accumulation of neutrophils, degeneration and necrosis of hepatocytes.Conclusions End to side portocaval shunt combined with common bile duct ligation and transection can produce a satisfactory acute hepatic failure model in canines, which could be used in the study of bioartificial liver.
