Objective To observe the imaging features of ultra-wide field short wave fundus autofluorescence (SW-FAF) in eyes with multiple evanescent white dot syndrome (MEWDS),and analysis the correspondence to conventional images.Methods It was a retrospective case series study.Thirteen patients (14 eyes) diagnosed with MEWDS were enrolled.There were 12 females and 1 male,aged from 22 to 57 years,mean age was 34.5 years.All the eyes underwent fundus color photography,optical coherence tomography (OCT) and ultra-wide field autofluorescence (FAF).Simultaneous fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 6 eyes.The characteristic changes of SW-FAF in studied eyes were observed and compared with the images of FFA and ICGA.All the eyes were followed up every 1 to 2 weeks,with an average of 16.7 weeks.The characteristic images of SW-FAF and corresponding OCT were studied during follow up.Results MEWDS presented with numerous multiple hyper-autofluorescent spots,sized from 50-500 μm,with a vague boundary in ultra-wide field SW-FAF.These spots located mainly at the peripapillary area and the posterior pole with a confluent pattern.The lesions extended to the mid-peripheral retina as well and became more scattered.The distribution of the hyper-autofluorescent lesions in SW-FAF corresponded roughly to that of the greyish-white spots seen in color photograph and the hyper-fluorescent spots detected by FFA.It was consistent with the distribution of hypo-fluorescent spots in late-phase ICGA as well.But the number of the spot showed in FAF is much more than that in FFA,and slightly less than that in ICGA.The OCT scans through the hyper-autofluorescent lesions in SW-FAF showed impairment of outer retina.After the recovery,the hyper-autofluorescent spots disappeared with the outer retina structure repaired completely.Conclusions MEWDS presented with numerous multiple hyper-autofluorescent spots which located mainly at the peripapillary area in ultra-wide field SW-FAF.The distribution of the hyper-autofluorescent lesions in SW-FAF corresponded roughly to color photograph,FFA and ICGA in late-phase.The OCT scans through the hyper-autofluorescent lesions in SW-FAF showed impairment of outer retina.

RBRVS assessment system has been carried out in hospital performance management,which meets the needs of the reform of public hospitals and hospital fine management.The one year practice at the hospital has built a new model of performance management based on the RBRVS assessment system.Calculation of the RVS point values and CF values of the operations and determination of such indexes as the indirect workload reference coefficient of the grades,will yield the amount of the performance bonus of individual departments and posts.The new model proved effective in improving staff incentives and efficiency,saving human resource cost and controllable materials.However,its design and implementation is a complex systematic engineering in need of measures suited to local conditions and steady progress.

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

Cryptotanshinone (CPT), a lipid soluble active compound in Salvia miltiorrhiza, has a significant inhibitory effect on multiple malignant tumors, e. g. chronic myeloid leukemia (CML) cells and can effectively enhance imatinib's chemotherapeutic effect. However, its functional molecular mechanism remained unclear. In this experiment, the authors conducted a systematic study on the effect of CPT on the imatinib sensitivity and P-glycoprotein (P-gp) expression in CML cells by using CML cells K562 and imatinib persister K562-R. The MTT assays were performed to determine CPT's impact on the inhibitory effect of imatinib. Annexin V-FITC/PI staining analysis was used to detect the changes in the cell apoptosis rate. The active changes in apoptosis regulatory proteins Caspase-3, Caspase-9 and PARP were determined by Western blot. After the cells were pretreated with the gradient concentration of CPT, the expression of P-gp was analyzed by Western blot and flow cytometry. The changes in intracellular concentrations of imatinib were determined by HPLC analysis. The results indicated that the pretreatment with CPT significantly increased the proliferation inhibiting and apoptosis inducing effects of imatinib on K562 and K562-R cells as well as the degradation product expression of pro-apoptotic proteins Caspase-3, Caspase-9 and PARP, with a significant difference with the control group (P < 0.01). However, CPT showed no impact on the P-gp expression in CML cells and the intracellular concentrations of imatinib. In summary, the findings suggested that CPT enhanced the sensitivity of CML cells to imatinib. Its mechanism is not dependent on the inhibition in P-gp expression and the increase in intracellular drug concentration.

Two Pseudomonas strains, K80 - B and K80 - A, can use hydrocarbon as carbon source by two different mechanisms. Different effects can be observed when they are applied to 69-8 oil of Dagan Oil Field. The strain K80-B producing both hydrocarbon pseudosolubilizing factor and hydrocarbon emulsifying factor can decrease the viscosity and solidifying point of the 69-8 oil 51.6% and 2℃ respectively. Whereas the other can only decrease 43.5% and 3℃ respectively. When the two strains are mixed, synergistic effect on crude oil is obvious.

The role of methyl-CpG binding domain protein 2 (MBD2) in an ApoE-deficient mouse model of age-related macular degeneration (AMD) was investigated. Eight-week-old Mbd2/ApoE double deficient (Mbd2(-/-) ApoE(-/-)) mice (n=12, 24 eyes, experimental group) and MBD2 (wt) ApoE(-/-) mice (n=12, 24 eyes, control group) were fed on Western-type diet for 4 months. The mice were sacrificed, and total serum cholesterol levels were analyzed and Bruch's membrane (BM) of the eyes was removed for ultrastructural observation by transmission electron microscopy. Moreover, intercellular adhesion molecule 1 (ICAM-1) immunoreactivities were evaluated by fluorescence microscopy in sections of the eyes in both groups for further understanding the function mechanism of MBD2. There was no significant difference in the total serum cholesterol levels between control group and experimental group (P>0.05). Transmission electron microscopy revealed that AMD-like lesions, various vacuoles accumulated on BM, notable outer collagenous layer deposits and dilated basal infoldings of retinal pigment epithelium (RPE) were seen in both groups, and the BM in control group was significantly thickened as compared with experimental group (P<0.05). Fluorescence micrographs exhibited the expression of ICAM-1 in choroid was higher in control group than in experimental group. We are led to conclude that MBD2 gene knockout may lead to accumulation of more deposits on the BM and influence the pathogenesis of AMD via triggering endothelial activation and inflammatory response in choroid, improving microcirculation, and reducing lipid deposition so as to inhibit the development of AMD-like lesions. Our study helps to provide a new therapeutic approach for the clinical treatment of AMD.
