AIM:To explore the diagnosis and treatment methods of radioaction-induced optic neuritis ( RION) through the clinical dates of 17 patients.
METHODS: It was a retrospective case series study. From August 2008 to October 2013, 17 cases (24 eyes) of Rion clinical dates from Chinese PLA General Hospital were studied. The diagnosis methods including visual acuity, pupil, fundus, visual field, fundus fluorescein angiography (FFA), visual electrophysiological testing, and head MRI. To analysis the clinical date of patients with diagnosis of RION by statistical description.
RESULTS: The deterioration degree of vision: 13 eyes were classified as Ⅳ, 9 eyes as Ⅲ, 2 eyes as II. Ten eyes RAPD ( + ) , visual electrophysiology is extinguished. The retina of 5 eyes showed flame hemorrhages and cotton wool spots exudation. Optic nerve head edema in one eye. T1 - weighted MRI enhanced in 19 eyes which showed optic nerve of the intracranial and intratubal segments abnormal changed, optic chiasm and pituitary stalk signal abnormalities and enhancement of the optic nerve. Tortuous optic nerves and rough edges were observed in 5 eyes. Treatment effect: 4 eyes of visual acuity improved, 1 eye from blindness to light perception,1 eye from 0. 08 to 0. 2, 1 eye from 0. 4 to 0. 6,1 eye from 0. 04 to 0. 15, the rest of the cases did not see any improvement.
CONCLUSION: The unique clinical manifestation of RION can provide objective basis for clinical diagnosis in time, but there have not been proven any effective treatments.

OBJECTIVETo study the effects of L.F04, the active fraction of Lycopus lucidus, on erythrocytes rheological property so as to investigate its mechanism in promoting blood circulation and removing blood stasis.

METHODThe effects of L.F04 (used for treatment for 10 days in different dosages) on deformability, aggregation and membrane liquidity of erythrocytes (MLE) as well as whole blood apparent viscosity (eta(b)) were examined on the basis of rat model of blood-stasis syndrome induced by venous injection of high molecular weight dextran.

RESULTAs compared with the normal control group, the model group's RBC deformability and MLE were lower, and the aggregation of erythrocytes and eta(b) were higher. Compared with the model group, both L.F04 0.612 g/kg and 0.306 g/kg showed significant effect in improving deformability and inhibiting aggregation of red blood cells (RBC) and reducing blood viscosity. The trend of improving MLE was also shown.

CONCLUSIONL.F04 could significantly improve the abnormal rheological property of erythrocytes.

To investigate the effect of flavonoids from Sophora flavescens in aging mice induced by D-galactose and its mechanism. Totally 60 mice were randomly divided into six groups: the control group, the model group, the piracetam group (positive control group) and flavonoids from S. flavescens low, medium and high doses groups. Except for the control group, all of the rest groups were subcutaneously injected with D-galactose (160 mg x kg(-1)) for successively 30 days to establish the sub-acute senescent model. Meanwhile, flavonoids from S. flavescens low, medium and high doses groups were respectively administered with 150, 300 and 600 mg xkg-('1)of flavonoids from S. flavescens for 30 days. The learning and memory abilities of mice were determined by avoiding darkness ex-eriment and jumping stair experiment. The contents of malondialdehyde (MDA) tumor necrosis factor-aα NF-aα the activities of superoxide dismutase (SOD) monoamine oxidase-B (MAO-B) Na'(+)K'(+)-ATPase and Ca2(+ )-ATPase in the brain of mice were deter-ined respectively after the behavioral experiments. The activity of lactic dehydrogenase ( DH) in blood serum was also determined and analyzed by microscope after HE staining to observe the changes in hippocampal organizational structure. Compared with the model group, flavonoids from S. favescens medium and high doses groups showed significantly increases in the latency of avoiding darkness and jumping stair experiments; flavonoids from S. fllvescens low, medium and high doses groups and the piracetam group showed de-reases in the numbers of errors in avoiding darkness experiment; the flavonoids from S. flavescens high dose group and the piracetam group showed reduction- n the number of errors in jumping stair experiment (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens me-ium and high doses groups and the piracetam group showed improvements in the activities of SOD, Na'(+)K'(+)ATPase in the brain of mice and declines in the contents of MDA and TNF-aα the activity of MAO-B in the brain of mice, the activity of LDH in blood serum (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens low, medium and high doses groups and the piracetam group also showed im-rovement in the activity of Ca2(+ )ATPase, with statistical difference from the model group (P <0 . 5 or P <0 . 1). The pathological result showed decreases in the number of cells of hippocampal dentate gyrus area, sparse cell arrangement, incomplete cellular mor-hology, scarce cytoplasm, blurred boundary between nucleus and cytoplasm, nuclei anachromasis, irregular pyknosis and unconspicu-us nucleoli in the model group. Compared with the model group, flavonoids from S. flavescens low, medium and high doses groups and the piracetam group showed improvements in hippocampal organization tissues. Flavonoids from S. favescens can improve the learning and memory ability of senescent mice induced by D-galactose. Its mechanism may be correlated with the enhancement of anti-oxidative actions by lowering TNF-aαcontent, which results in the stability of cell membrane and the reduction in MAO-B activity.

PURPOSE: Triple-negative breast carcinoma (TNBC) is accompanied with high risk of metastasis and recurrence. The present study aimed to explore the clinicopathological and prognostic roles of putative tumor-related genes in patients with TNBC. METHODS: Thirty pairs of frozen-thawed tumors were used to select reliable indicators via real-time quantitative polymerase chain reaction (RT-qPCR). Then, 150 pathology specimens were used to evaluate the expression of proteins in TNBC through immunohistochemistry. In addition, Kaplan-Meier curves and Cox regression analysis were also performed to analyze the overall survival and disease-free survival. RESULTS: RT-qPCR results indicated that among all the proteins analyzed using fresh-frozen TNBC samples, the expression levels of only Survivin and zinc finger of the cerebellum 1 (ZIC1) were obviously different from those in the corresponding normal tissues. Survivin and ZIC1 expression had opposite effects on the clinicopathological diagnosis and prognostic assessment in TNBC patients. Further, there was a negative correlation between Survivin and ZIC1 expression. In addition, the “Survivin-positive ZIC1-negative group” was associated with histologic grade, lymph node metastasis, and TNM staging (p < 0.001) and this was also an independent factor for evaluating the prognosis of TNBC in patients. CONCLUSION: In summary, the expression levels of Survivin and ZIC1 in TNBC are different from those in normal tissues and are negatively correlated mutually. The combined detection of Survivin and ZIC1 expression levels could allow better comprehensive diagnosis and prognostic evaluation for TNBC patients.

OBJECTIVETo assess the diagnosis and treatment of invasive lung aspergillosis after liver transplantation.

METHODSRoutine sputum culture was performed. Itraconazole and fluconazole were used to prevent fungal infection prophylactically. Amphyotericin B was only used on aspergillosis. In 54 patients receiving, liver transplantation, 3 patients with lung aspergillosis were reviewed.

RESULTSOf the 3 patients 2 died and 1 recovered.

CONCLUSIONSOver-immunosuppression is a main risk factor for aspergillosis. Amphotericin B is still the best choice for the treatment of aspergillosis and its gradual, interrupted, low concentration administration, cooperated with itraconazole can ease the side effects.

BACKGROUNDPrevious studies have showed that photooxidative stress can lead to down-modulation of nuclear factor-kappa B (NF-kappaB) activity causing apoptosis of cultured photoreceptor cells. This study aimed at investigating whether NF-kappaB was involved in photoreceptor cells apoptosis induced by N-methyl-N-nitrosourea (MNU) in rats.

METHODSA single intraperitoneal injection of 60 mg/kg MNU was given to 50-day-old female rats. At different intervals after MNU treatment, the animals were sacrificed. Retinal damage was examined by a light microscope. The apoptotic index of the photoreceptor cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling (TUNEL). NF-kappaB was analysed by Western blot and Transcriptin Factor Assay Kits.

RESULTSThe pyknosis of the photoreceptor nuclei and the disorientation of the outer segment of the photoreceptor layer was seen after MNU treatment for 24 hours. The outer nuclear layer and photoreceptor layer were almost completely lost at 7 days. Photoreceptor cells apoptosis reached the peaked value at 24 hours. In apoptotic cascade, the protein levels of NF-kappaB p65 were only detected after MNU treatment for 12 and 24 hours in the nucleus. Conversely, the amounts of IkappaBalpha were markedly increased in the cytoplasm as well as in the nucleus. The activity of NF-kappaB p65 in the nucleus was down-modulated in the end.

CONCLUSIONSMNU-induced photoreceptor cell destruction was attributed to the apoptotic process by down-regulating the activation of NF-kappaB p65.

OBJECTIVETo observe the changes of nuclear factor-kappa B (NF-kappaB) in the course of N-methyl-N-nitrosourea (MNU)-induced apoptosis of rat retinal photoreceptor cells and investigate the mechanism of MNU-induced retinal damage.

METHODSA single intraperitoneal injection of 60 mg/kg MNU was given to 50-day-old female rats, which were sacrificed at different intervals after MNU treatment. The retinal damage was examined with optical microscopy and photoreceptor cell apoptosis detected by TUNEL assay. Western blotting was performed to analyze the changes in NF-kappaB.

RESULTSPyknosis of the photoreceptor cell nuclei and disorientation of the outer segment of the photoreceptor layer was observed 24 h after MNU treatment, and the outer nuclear layer and photoreceptor layer were almost completely lost on day 7. Photoreceptor cell apoptosis peaked at 24 h, and in the apoptotic cascade, NF-kappaB p65 protein was only detected 12 and 24 h after MNU treatment, whereas the amount of I kappa B alpha, in contrast, markedly increased in the cytoplasm as well as in the nuclei.

CONCLUSIONMNU-induced retinal damage might be mediated through the signaling pathway of NF-kappaB/I kappa B alpha.

BACKGROUNDBacterial pneumonia in the recipients of liver transplantation (LTX) is a common postoperative complication influencing the prognosis greatly. In this article, the diagnosis and treatment of bacterial pneumonia in 33 LTX recipients are reported.

METHODSFrom February 1999 to January 2003, a total of 103 patients underwent allogeneic LTX at our center; afterwards, a retrospective analysis was made on their postoperative clinical manifestations, including symptoms (expectoration, panting and fever), sign (rale), results of laboratory examinations (white blood cell count and sputum culture of tracheal secretions or pleural fluid culture), and chest X-ray films. The following data of the pneumonia and non-pneumonia groups were collected, and the rank sum test (SPSS 11.0, Wilcoxon's method) was used to analyze the duration of postoperative respirator utilization and the volume of pleural effusion through pleurocentesis or pleural drainage.

RESULTSIn the 103 patients, 33 experienced 53 episodes of bacterial pneumonia during their hospital stay after transplantation, 14 of them (42.42%) had more than three manifestations of the seven mentioned above. The pathogens causing bacterial pneumonia included Pseudomonas aeruginosa (17.48%), Klebsiella pneumoniae (15.53%), Acinetobacter baumannii (10.68%), and Staphylococcus aureus (7.77%). Amilkacin, tienam, ciprofloxacin, vancomycin, etc. were the antibiotics of choice against those bacteria. Acute rejection occurred during the treatment of bacterial pneumonia in 16 patients, and 5 of them died. Wilcoxon's rank sum test of the data indicated that the pneumonia group had longer duration of postoperative ventilator treatment and larger volume of pleural effusion than the non-pneumonia group (P < 0.05).

CONCLUSIONSThe clinical manifestations of pneumonia after LTX might be atypical, and special attention should be paid to the respiratory symptoms and signs within 2 months after LTX. Whenever the diagnosis of bacterial pneumonia is confirmed, consideration should be given to reasonable use of antibiotics and regulation of immunity in addition to other routine therapies.
