RESUMO
Objective To investigate the value of combined detection of alpha fetoprotein (AFP) ,gamma-glutamyl transferase (GGT)and Golgi glycoprotein (GP73)in the diagnosis of primary hepatocellular carcino-ma.Methods 109 cases of primary liver cancer treated in the hospital from June 2015 to June 2017 were en-rolled in the study as primary liver cancer group ,76 cases of liver cirrhosis were enrolled in the study as liver cirrhosis group and 70 cases of healthy people who underwent healthy assessment were enrolled in the study as control group.The peripheral venous blood in each group was extracted fasting in the morning ,and the ser-um was separated.The levels of GP73 were measured by enzyme linked immunosorbent assay.The level of AFP was measured by chemiluminescent immunoassay ,and the level of GGT was measured by rate method. Results The serum levels of AFP ,GGT and GP73 in the primary liver cancer group were higher than those in the liver cirrhosis group and the control group ,and the serum levels of AFP ,GGT and GP73 in the liver cir-rhosis group were higher than those in the control group ,and the differences were statistically significant (P＜0.05).The specificity and the sensitivity of the combined detection of AFP ,GGT and GP73 were higher than those of single detection of AFP ,GGT ,and GP73.Conclusion The combined detection of AFP ,GGT and GP73 has important value in the diagnosis of early primary liver cancer ,and has relatively high sensitivity and specificity ,which is worthy of further clinical study.

Objective To study the effects of chronic manganism on hearing and cochlear cells in rats by using animal model of chronic manganism .Methods Sixty adult SD rats were randomly divided into Mn - exposed and controlgroups.RatsweretreatedwithMnCl24H2O(100mg·kg -1·d-1)ordeionizedwaterbygastricperfusion, lasted for 12 weeks .The Mn concentration in peripheral blood was measured respectively at 4 weeks ,8 weeks and 12 weeks after treatment .At 12 weeks after treatment ,the auditory brainstem response was recorded ,the hair cells morphology and counting were examined by stretched preparation of basilar membrane stained with FITC -phalloi-din ,and the spiral ganglion cells morphology and counting were studied by HE staining ,the ultrastructure changes of hair cells and spiral ganglion cells were detected by transmission electron microscopy .Results The blood Mn concentration increased gradually with time after treatment .ABR thresholds at 4 ,8 ,16 ,24 and 32 kHz were sig-nificantly increased at 12 weeks after treatment ,especially in the high-frequency range .Morphological study at 12 weeks after treatment showed loss of outer hair cells ,mainly in the basal turn of the cochlea ,and decreased number of spiral ganglion cells .The ultrastructure changes of outer hair cells and spiral ganglion cells included the break -ups ,disappearance or vacuolar change of mitochondria cristas .Conclusion Our data demonstrate that chronic man-ganism can cause loss of outer hair cells and spiral ganglion cells in cochlear in rats ,leading to hearing loss .
RESUMO
Objective The study aimed to explore the relationship between AIF related pathway and the inju-ring of cultured SGNs (spiral ganglion neurons)by glutamate toxicity,and to find AIF expression and distribution changes in SGNs.Methods SGNs of 40 newborn rats within 3 day were obtained and cultured in vitro.Cultured cells were divided into four groups:the normal control group,10 mM,20 mM and 40 mM glutamate injured group, separately.After 48 h hours culturing,optical microscopy,immune fluorescence staining and real-time fluores-cence quantitative PCR were used to observe the morphology,AIF distribution,and AIF,calpain,Caspase3 expres-sion changes in SGNs in vitro.TUNEL was used to verify the cell apoptosis.ResuIts Noticeable morphological chan-ges and cell apoptosis were occurred in 20 mM glutamate group,with AIF nuclear translocation.AIF gene expression was significantly higher than normal after glutamate administration (P0.05). ConcIusion In the process of cultured SGNs injured by glutamate,AIF participated in the cell apoptosis.Noticeable cell apoptosis were occurred in 20 mM glutamate group with AIF nuclear translocation.Calpain up-expression also contributed to excitatory neurotransmitter injury on SGNs,but Caspase 3 had no obvious effects.

Objectiye To investgate the effects of isoflurane preconditioning on expression of Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) during focal cerebral ischemia-reperfusion (IR) in rats. Methods Thirty male SD rats weighing 250-300 g were randomly divided into 3 groups ( n = 10 each):sham operation group (group S);focal cerebral IR group and isoflurane preconditioning group (group IP). The animals were anesthetized with intraperitoneal pentobarbital 40 mg/kg. In group IR and IP a nylon thread with rounded tip was inserted into right internal jugular vein and threaded cranially until resistance was met. Mid-cerebral artery was occluded (MCAO) for 2 h followed by 24 h reperfusion. In group IP the animals inhaled 2% isoflurane98 % O2 for 1 h once a day for 5 consecutive days at 24 h before MCAO. Neurologic function was assessed and scored and cerebral infarct volume was measured at 24 h of reperfusion. The animals were sacrificed at 24, 48 and 72 h of reperfusion respectively. The right ischemic frontal lobes were removed for determination of TLR4, MyD88and NF-κB expression by Western blot analysis. Results MCAO significantly worsened neurologic function. The neurologic function deficit scores were significantly increased and the TLR4, MyD88 and NF-κB expression were significantly up-regulated in group IR as compared with group S (P ＜ 0.05). Isoflurane preconditioning significantly decreased cerebral infarct volumes and neurologic function deficit scores and down-regulated the expression of TLR4, MyD88 and NF-κB in group IP as compared with group IR ( P ＜ 0.05). Conclusion Isoflurane preconditioning can reduce inflammatory response and focal cerebral IR injury by down-regulating the expression of TLR4and Myd88.
