In order to explore the MRI volume of the amygdala and hippocampus in patients with major depression, quantitative MRI of the amygdala and hippocampus were studied in 22 patients with major depression and compared with 13 age-matched controls. The results showed that both groups exhibited similar significant hippocampal asymmetry (left smaller than right). The volume of the bilateral hippocampus was significantly smaller in the major depression group than that in control group. The patients had significant asymmetry of the amygdalar volumes (right smaller than left). No correlation was found between hippocampal volume abnormalities and ill duration. It was concluded that the hippocampus and amygdala within limbic-cortical networks may play a crucial role in the pathogenesis of major depression.

To enhance the production of ε-poly-L-lysine (ε-PL) by improving dissolved oxygen level of the fermentation system, different oxygen-vectors were added to broth and n-dodecane was screened as the best oxygen-vector. The best amount of n-dodecane was 0.5% (V/V) and the best time was at start of the fermentation. In a fed-batch fermentation in a 5 L bioreactor, ε-PL concentration reached a maximum of (30.8 ± 0.46) g/L and the dry cell weight obtained was (33.8 ± 0.29) g/L, increasing by 31.6% and 20.7% compared with the control group, respectively. This improvement can be related to 0.5% n-dodecane could maintain dissolved oxygen concentration > 32% of air concentration compared with 23.8% in ε-PL production phase, and the production of a main by-product, poly-L-diaminopropionic acid, fell by 31%. These results indicated that the dissolved oxygen level in the broth was improved by adding n-dodecane, which can inhibit the by-product production and improve the biosynthesis of ε-PL.

Objective In order to play the role of pathological network management system better in pathological examination, this study explore the present status of new pathology network management system, give an objective evaluation for the operation condition, reveal the effectiveness and the existing problems of this system, and provide reference for its development and improvement.Methods The software of pathological network management system was applied to the pathological specimen reception, patient information and examination status query, pathological diagnosis and technology process, as well as the paraffin block archive, statistical analysis, data recording, and so on.At last, we recorded all the information and made a classification and arrangement.Results Pathological network management system was running normally through the whole process of pathologic examination, including specimen receiving, all examinations, print of pathological applications and spontaneous print of pathological reports in ward, which really achieve one-stop services.But the system has unstable phenomenon occasionally.Conclusion Pathological network management system links each examination process closely, which can improve the work efficiency, and provide scientific basis for pathology quality control.

Objective When pathologists from hospitals at various levels encounters pathological sections diffcult to make clear diagosis, it is necessary to invite pathologists from higher hosiptals or special hospitals for pathologic consultation.In the study, we compared the pathological diagnosis of cases sent to other hospitals for pathological consultation with the original diagnostic result to analyze the differences by the evaluation on the impact of these differences on the treatment and prognosis of these patients, which would provide an effective evidence for the quality control of pathological diagnosis. Methods Cases initially diagnosed at the de-partment of Nanjing General Hospital and later sent to other hospitals for pathological consultation from 2010 to 2014 were collected. All the diagnostic results were examined by at least 3 senior pathologists to find exact diffrences between consultation results and origi-nal diagnostic results. Results Among 2055 cases, it was found that there were 1813 cases (88.2%) without diagnostic discrepan-cy, while 218 cases (10.6%) with minor diagnostic discrepancy and 24 cases (1.2%) with completely distinct diagnostic results. Conclusion The diagnostic results of the vast majority of consultation cases are in accordance with the original results, despite of di-agnostic discrepancies in some cases due to the complexity of disease. Expert consultation has reference for the pathological diagnosis of complicated cases, which also plays a potent supervisory role on the quality control of original pathologic results.

OBJECTIVETo establish chemiluminescence enzyme immunoassay (CLEIA) for quantitative detection of procollagen III N-terminal peptide (P III NP) in serum.
METHODSA sandwich reaction was preformed with horseradish peroxidase labeled monoclonal antibody of P III NP as the catalytic enzyme and the luminol as the luminescence reagent. Several reactions liquid's concentration and reaction conditions were optimized. The method was evaluated in all aspects such as linear range, sensitivity, specificity, stability and so on. The CLEIA was compared with imported ELISA kits, by detecting clinical serum.
RESULTSThe linear range was 0.8-85 ng/ml. The detection limit was 0.5 ng/ml. Inter-assay and intra-assay RSD were both less than 10%. The recoveries of three different spiked concentration samples were 96.2%, 91.2% and 101.1%. After stored at 4 degrees C and 37 degrees C for 3, 5, 7 days, the analysis showed correlation coefficient higher than 0.99 and RSD lower than 6%. The detected results of clinical sera with CLEIA closely corresponded to those with imported ELISA.
CONCLUSIONEstablished CLEIA for quantity determination of serum P III NP has high accuracy, sensitivity and repeatability.
