In the early stage of tumor,the diagnosis index of objective and definite is often deficient,which brings great trouble to the treatment.How to find some valuable markers or characteristic changes in the early stage of cancer is the key problem to be solved by the medical experts.With the development of flow cytometry (FCM),it is playing a more and more important role in precancerous lesion screening,early detection of cancer,chemotherapy guidance and prognosis assessment.In personalized medicine and precise medical background,the application of FCM in tumor marker detection,cancer stem cells separation screening,isolation and identification of circulating tumor cells is especially worth looking forward tc.

Objective To investigate the comparability of K + ,Na+ and Cl- measurement between Cobas8000 analyzer and AU640 analyzer .Methods According to the EP9‐A2 document of the National Committee for Clinical Laboratory Standards ,the precision of AU640 analyzer for the detection of K + ,Na+ and Cl- was evaluated ,and the correlation between the detected results of the two analyzers were also analyzed .Results AU640 analyzer were with high precision for the detection of K + ,Na+ and Cl- ,in‐tra‐assay and inter‐assay coefficient of variation of which were both less than 2% .The correlation coefficients of the two analyzers were higher than 0 .975 .Conclusion Cobas8000 analyzer and AU640 analyzer might be with fine comparability for the detection of K+ 、Na+ and Cl- ,both of which could provide accurate detected results .

Breast reconstruction after radical mastectomy significantly improves the patient' s quality of life and has become an important part of comprehensive treatments. However, there are a number of reconstruction problems. The choice of breast reconstruction after breast cancer should be considered in general. Immediate reconstruction is not superior to breast-conserving surgery, while immediate reconstruction is superior to delayed reconstruction, and choices vary between implant reconstruction and autologous reconstruction. In short, breast reconstruction should be based on the radical principle with balance of beauty.

Objective To explore the pattern of cognitive impairments mainly caused by the white matter lesions(WML) in the frontal lobe in patients with subcortical ischemic vascular disease (SIVD).Methods Fifty SIVD patients were divided into severe WML group (visual score >3, n=27) and mild WML group(visual score ≤3, n=23) according to their severities of the WML in frontal lobe .Seven patients without SIVD were collected as controls .All patients underwent a set of neuropsychological battery ,and the results were analyzed .Results There was no statistical significance among three groups on basic data .Compared with mild WML group and control group , non frontal white matter scores and numbers of lacunes in frontal lobe of severe WML group were significantly higher ( all P=0.000).Compared with mild WML group,the Montreal cognitive assessment scale in severe WML group were significantly lower ( P=0.047 ) , and scores related to the executive function were significantly lower ( P=0.006 ) , even after adjusting the numbers of lacunes in frontal lobe ,there was statistically significant difference (P=0.038). Multiple regression confirmed that the Z scores of executive functions were mainly affected by white matter lesions located in the frontal lobe ( P=0.000 ) .Conclusion WML located in the frontal lobe mainly affect the executive function in patients with SIVD .

The primary function of optical in vivo imaging technique is tracing and detecting the action and expression of maker cells,maker microorganisms and maker molecules.This technique makes possible the noinvasive study of biological events continuously with high sensibility,simplicity and high speed.It has been applied in numerous research fields.This paper presents a review of principle and application of this technique.

Bacillus cereus B-04 antagonist to Botrytis cinerea were isolated from samples of tomato soil infected by Botrytis cinerea in Zibo, which are identified through a series of morphological and biochemical characteristics and the sequence of 16SrDNA. Aiming at enhancing the inhibitory effect of this strain, a 4.1kb DNA fragment containing ?-1,3-glucanases gene from pUC1940 was inserted into vector pBE2 and pHY300PLK to construct recombination plasmids, PBE2-glu and pHY300PLK-glu, which were transferred into Bacillus cereus B-04, resulting in a new strain named B-04-glu. Restriction enzyme digestion and ?-1,3-glucanases plate culture confirmed that B-04-glu contained a functional ?-1,3-glucanases gene. Compared to the wild strain B-04, B-04-glu had an increased inhibitory effect against Botrytis cinerea on tomato.
