BACKGROUND: Organ for transplantation is insufficient, and primary transplant of nonfunction caused by perfusion cryopreservation occasionally occurs. It is clinically significant to reduce organ damage caused by perfusion preservation. OBJECTIVE: To explore the protective effect of hyperoxic perfusion fluid on liver transplantation in rats. METHODS: A total of 40 Wistar rats were randomly divided two groups (n = 20) and respectively poured with Ringer lactate solution or hyperoxic ringer lactate solution. Each group comprised equal number of donors and recipients to prepare liver, kidney, and pancreas transplantation models. Hyaluronic acid (HA), alanine aminotransferase (ALT) and CD8+CD28- T cells were compared between two groups at the end of perfusion, and 1st and 3rd days after liver transplantation. The acute rejection score of liver tissues were also compared after operation. RESULTS AND CONCLUSION: The HA, ALT and CD8+CD28-T cells were no significantly different between two groups before operation (P> 0.05). The HA and ALT of hyperoxic ringer lactate solution group was significantly Ringer lactate solution group after liver transplant (P < 0.05), but the CD8+CD28-T cells were greater (P < 0.05). The acute rejection scores for liver in hyperoxia liquid group were significantly less than the common liquid group (P< 0.05). Results show that hyperoxic solution can attenuate ischemia/reperfusion injury and protect rats undergoing liver transplantation.

A new analytical method has been developed for the simultaneous determination of CrⅢand CrⅥusing on-line sample pretreatment valve-switching ion chromatography. The organic matrix in leather was removed by using a reverse-phase column as the pretreatment column. Before injection, EDTA was added into sample solution to react with the CrⅢto form anion which could absorb visible light strongly. After injection, the ions separated by the pretreatment column were received in a collection loop. Then the ions were delivered into an analytical column and separated. CrⅥ then was derived with the derivatization reagent 1, 5-diphenylcarbazide ( DPC) , and detected together with CrⅢ-EDTA complex by a UV-Vis detector. Under the optimum conditions, the linear range of the method for CrⅢ and CrⅥ was 0. 3-10 mg/L (r=0. 9991) and 0. 05-2 mg/L ( r = 0. 9992 ), whereas detection limits ( S/N = 3 ) were 80. 78 μg/L and 6. 67 μg/L, respectively. The recoveries were in the range of 88. 7%-108. 5% with the relative standard deviations for retention time and peak area less than 3%. The method could be applied to determine CrⅢ and CrⅥ in leather and cloth effectively and quickly.

We report here a case of myelitis of the cervical spinal cord in a 59-year-old woman presented with right arm weakness and numbness. Cervical myelitis developed three weeks after the eruption of zoster rash from the C2 to C5 dermatomes. The serum aquaporin-4 antibody was detected using the cell based transfection immunofluorescence assay. MRI of the cervical spine revealed abnormal cord signal. Cerebrospinal fluid analysis demonstrated varicella-zoster virus DNA was not detected. The patient was diagnosed with neuromyelitis optica spectrum disorder, supporting the hypothesis that the pathogenesis of neuromyelitis optica spectrum disorders is triggered by infection.

BACKGROUNDTo study etiology of clinically diagnosed non A-E hepatitis.

METHODSHBV, TTV, human parvovirus B19, SENV DNA were detected by nested polymerase chain reactions (nPCR), while HGV, HCV RNA were tested by reverse transcription nested polymerase chain reactions (RT-nPCR).

RESULTSOf 60 patients with clinically diagnosed non A-E hepatitis, 30 (50.0%) were HBV DNA positive alone, 10 (16.7%) HBV and TTV DNA positive, 6 (10.0%) HBV and B19 DNA positive; 1 (1.7%) HBV, SENV DNA and HCV RNA positive, 1 (1.7%) HCV RNA positive alone, 1 (1.7%) HCV RNA and B19 DNA positive, 2 (3.3%) B19 DNA positive alone, 1 (1.7%) TTV DNA positive alone, and the remaining 8 (13.3%) negative for all viruses. All the 60 patients were HGV RNA negative. There were no differences in serum biochemical markers of hepatitis B patients with or without TTV or B19 virus infection.

CONCLUSIONSHBV is a major etiologic agent for the clinically diagnosed non A-E hepatitis. HGV, TTV, B19 and SEBV may not be associated with nonA-E hepatitis.

The role of the high mobility group box 1 (HMGB-1) in acute hepatic failure and the ef- fect of artificial liver support system treatment on HMGB-1 level were investigated. Pig models of acute hepatic failure were induced by D-galactosamine and randomly divided into two groups with or without artificial liver support system treatment. Tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) levels were detected by the enzyme linked immunosorbent assay (ELISA), the expression of HMGB-1 by Western blot, and serum levels of HMGB-1, liver function and hepatic pathology were observed after artificial liver support system treatment. The levels of TNF-α and IL-1β were increased and reached the peak at 24th h in the acute hepatic failure group, then quickly decreased. The serum level of HMGB-1 was increased at 24th h in the acute hepatic failure group and reached the peak at 48th h, then kept a stable high level. Significant liver injury appeared at 24th h and was continuously getting worse in the pig models of acute hepatic failure. In contrast, the liver injury was significantly alleviated and serum level of HMGB-1 was significantly decreased in the group treated with artificial liver support system (P＜0.05). It was suggested that HMGB-1 may participate in the inflammatory response and liver injury in the late stage of the acute liver failure. Artificial liver support system treatment can reduce serum HMGB-1 level and relieve liver pathological damage.
