Objective To investigate the effects of ?-lipoic acid on the proliferation and activation of NF-?B induced by high glucose (HG) in rat mesenteric cells (MCs). Methods The rat mesenteric cells were cultured in the medium with normal glucose (5.6mmol/L, NG), high glucose (25mmol/L, HG), HG+100 ?mol/L ?-lipoic acid, or HG+200?mol/L ?-lipoic acid and HG+PDTC (a NF-?B inhibitor). Activation of nuclear factor-?B (NF-?B) of rat mesenteric cells were measured by electrophoretic mobility shift assay (EMSA). The cell proliferation was assessed by MTT. Results ?-lipoic acid (50~300?mol/L) can inhibit the proliferation of MCs. The NF-?B binding activity was 2.2 -fold higher in MCs exposed to HG compared to NG (P

Objective To provide anatomical information and clinical application of flaps based on the proximal ulnar artery perforators.Methods Ten fresh cadavers who underwent injected with artery imaging technology and dissected with layer by layer;Eighteen patients who sought surgical treatment with proximal ulnar artery perforator flap for soft tissue defects of the finger and dorsum wrist at our hospital between October 2011 and November 2012 were included in this study.Results The diameter and superficial length of the main perforator respectively were 0.5-0.9 mm and 33.0-47.0 mm in our dissection.There were 5-9 perforators given from the ulnar artery to supply skin over the medial side of the forearm.All of the 18 flaps survived after surgeries.The flap size ranged from 3.0 cm × 2.5 cm to 10.0 cm × 5.5 cm.All of the transplanted flaps presented favourable contours and good functions at 6 to 12 months' followed-up.Conclusion Proximal ulnar arter perforator flap has favourable appearance,constant vascular pedicle,reliable blood supply,and large diameter.The free transplantation of this flap offers a satisfactory alternative for repairing the small and medium-sized area of soft tissue defects of forearm and hand.

There has been no specific therapeutic measures for acute lung injury /acute respiratory distress syndrome ( ALI/ARDS) , a disease of high fatality rate.Besides having good curative effects for the cardiovascular system diseases, cancer, obesity and preventing aging, traditional Chinese herbal medicines also have obvious therapeutic effects on ALI/ARDS.In this paper, we summari-zes the protection and the underlying mechanisms of traditional Chinese herbal medicines on ALI/ARDS.

Objective To investigate the effect of small interfering RNA (siRNA) suppressing discoidin domain receptor 1 (DDR1) gene on biological behaviour of Kupffer cells (KC) in acute hepatic injury. Methods Male BALB/c mice were randomly divided into control, hepatic injury model, non-silencing siRNA and DDRlsiRNA groups. Hepatic injury model induced by intravenous injection of Con-canavalinA (ConA) 15 mg/kg, with or without hydrodynamic tail intravenous injection of naked siRNA (50 μg,2.0-2.5 mg/kg)/mouse or 1.5 ml normal saline. The expression of DDRI was assayed by West-ern blot and pro-inflammatory cytokine expression analyzed by ELISA. In the meantime, alanine amin-otransferase (ALT) and Kupffer cells'clearance to carbon granules was detected. Results The expres-sion of DDR1 obviously increasod at 6 h after hepatic injury, roached peak at 24 h and began to decrease at 48 h. Pretreatment with DDRisiRNA could obviously inhibit the expression of DDR1 and abrogate the high levels of ALT, expressions of TNF-α and IL-1β as well as phagocytosis of Kupffer cells. Conclu-sions Inhibition of discoidin domain receptor 1 by in vivo delivery of siRNA attenuates ConA-induced hepatic injury. Possible mechanism is that the inhibition of activity of KC inhibits the expression of pro-in-flammatory cytokines and thus alleviates hepatic injury.

Objective To explore the optimal surgical treatment strategy of advanced gallbladder carcinoma (Nevin Ⅲ - Ⅴ ), with an aim to prolong patients' overall survival. Methods 17 patients with advanced gallbladder carcinoma were reviewed. Their preoperative diagnosis, surgical treatment, complications and survival time were studied. Results The diagnosis of advanced gallbladder carcinoma was done using different medical imaging techniques, but incorrect diagnosis still happened. There is a wide range of surgical treatment for advanced gallbladder carcinoma. Controversy still exists as whether lymph node resection should be done. In our patients, 35.3% of the 13a lymph nodes and 23. 5% of the 8 lymph nodes were positive for metastasis, which showed that lymph node resection should be carried out. Extended surgery was sometime required to ensure a R0 resection.The main complications of surgery were intraabdominal infection, bile leakage and paralytic ileus.Conclusion An aggressive surgical approach for advanced gallbladder carcinoma is required to ensure a R0 resection, which contributed to better overall survival.

A novel amplifier system was proposed for low-noise recording of pico-ampere current in nanopore experiment (<100 pA). As an example, the amplifier system was applied in α-hemolysin based nanopore detection of DNA-PEG-DNA conjugate to record the signals of translocation and bumping events in buffer solution (1 mol/L KCl, 10 mmol/L Tris--HCl, 1 mmol/L EDTA and pH=8. 0). The amplified current signal was filtered by a 3 kHz Bessel filter and sampled by a 100 kHz analog-digital convertor. As a result, the presented amplifier system could lower the noise in recording the current. The current blockages (<10 pA) of single molecules with low amplitude were recovered due to the high signal-to-noise ratio.

Objective To investigate the safety and therapeutic effects ot a novel multi-layer flat-plate bioartificial liver (BAL) for patients with liver failure.Methods Thirty-eight patients with liver failure from Dec.2010 to Dec.2011 were treated with a novel BAL based on multi-layer flatplate bioreactor and the co-cultured cells of the porcine hepatocytes and mesenchymal stem cells.A total of 48 treatments was performed,4 h each time.The clinical signs and symptoms,liver function,ammonia,coagulation function and complete blood count were evaluated before,during and after the treatment.DNA in the collected PBMCs was extracted for PCR with PERV specific primers and the porcine specific primer Sus scrofa cytochrome B.The RT activity was detected as well.Levels of xenoantibodies (IgG,IgM) were determined by using ELISA kit. Titers of complement were quantified by CH50 kit.Results All treatment procedures were completed successfully without any adverse reaction. All samples presented negative PERV DNA and RT activity. The levels of antibodies were similar before and after treatment.Treatment was associated with a temporary decline in levels of complement,and then the levels were recovered quickly.The clinical symptoms such as acratia,anorexia and abdominal distension were improved.The stage of hepatic encephalopathy in 16 patients was decreased. The liver function and ammonia was reduced disproportionately. Seven patients in all were bridged to liver transplantation,2 patients died and 2 patients gave up the treatment,and the others were turned better.After the outcome judgment according to the standard developed by the Artificial Liver Group,and Chinese Association of Infectious and Parasitic Diseases,there were 9 patients with clinical healing,25 patients with improvement and 4 patients with no effect,and the cure-improvement rate was 89.5％.Conclusion The novel multi-layer flat-plate BAL could be used as a safe and effective therapy for patients with liver failure.
