Objectives To learn the effect of self-recognition-based healthy management on community diabetics. Methods A total of 40 community diabetics were evaluated and trained for 3 months.SPSS11.5 software was used for data analysis. Results At 3 months, some risk factors of diabetes,including body weight, body mass index (BMI), waist circumstance (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP) and 2 h postprandial blood sugar (PBS), were improved (P ＜0. 05). Male patients showed statistically significant reduction in body weight, BMI and WC ( P ＜ 0. 05 ).However, female subjects were found to have significant decline in body weight, BMI, WC, SBP and DBP (P＜0. 05). Those ＞60 year-old had significantly decreased body weight, BMI, WC, SBP, DBP and 2 h PBS ( P ＜ 0. 05). Lower levels of WC, SBP and triglyceride were seen in individuals ＜ 60 year-old ( P ＜0. 05 ). Conclusion Self-recognition-based healthy management could effectively reduce diabetic risk factors and prevent the development of diabetic complications.

The traditional view of bacterial life cycle consists of four phases,namely,lag phase,exponential or logarithmic phase,stationary phase and death phase.Although the standard textbook description of the bacterial life cycle has been useful,might not always provide us the whole visage of bacteria growth process.Recently,it has demonstrated that bacterial life cycle is expanded to five phases.It is a significant different growth phase after death phase:long-term stationary phase,which may be more akin to the nature environment in which microorganisms exist.Microbial cells survive due to mutating,and forming growth advantage during stationary phase (GASP) phenotype in this phase.It is very important for further study the microorganisms in this phase.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.

To investigate the relationship between LRP15 gene promoter region methylation and its gene expression in acute leukemia patients, the status of LRP15 gene promoter region methylation was detected by MS-PCR and the gene expression was detected by RT-PCR in bone marrow samples from leukemia patients. The results indicated that the LRP15 gene expression was 47.6% in complete remission (CR) patients and 16.7% in non-CR patients respectively, while LRP15 gene promoter region methylation was 38.1% in CR group and 72.2% in non-CR group respectively. No relationship was found between LRP15 gene promoter region methylation and its expression (P = 0.0087). It is concluded that the methylation in LRP15 gene promoter region may not be the only reason for LRP15 gene silence.

OBJECTIVETo investigate the possibility of dynamic magnetic resonance (MR) perfusion-weighted imaging (PWI) in rabbit models of implanted hepatic VX2 tumor.

METHODSMRI and PWI images were obtained from 16 rabbit models of implanted hepatic VX2 tumor and 4 normal rabbits at 14, 18, 22, and 26 days after tumor implantation, respectively, and the mean time to enhancement (MTE) and maximum slope of increase (MSI) were estimated and compared with pathological changes.

RESULTSIn the rabbit models of implanted hepatic tumor the MTE tended to increase and MSI to descend 14, 18, 22, and 26 days after tumor implantation, showing significant differences from the control group. Coagulation necrosis and fibrous hyperplasia in the tumors appeared to progress with time as found pathologically.

CONCLUSIONDynamic MR PWI quantitative analysis of rabbit models of implanted hepatic VX2 tumor provides valuable means for observing the growth behaviors of VX2 tumor and may be clinically applicable in the evaluation of hepatic diseases.

To explore the value of detection of PML/RARalpha gene rearrangement on bone marrow smears (BMS) by dual-color fluorescence in situ hybridization (D-FISH) for the diagnosis of acute promyelocytic leukemia (APL), the locus-specific probes for PML and RARalpha genes labeled directly and respectively by Spectrum Green and Spectrum Orange and the D-FISH technique were used to detect the PML/RARalpha gene rearrangement on BMS in 27 suspected APL patients. The results were compared with that of conventional cytogentics (CCG) and reverse transcriptase polymerase chain reaction (RT-PCR). The results showed that out of 18 newly diagnosed patients 14 were found having t(15;17) translocation by CCG and PML/RARalpha gene rearrangement were confirmed by BMS-D-FISH and RT-PCR. Thus, their APL diagnosis was determined; out of 4 patients in whom t(15;17) translocation was not detected by CCG, one had positive BMS-D-FISH and RT-PCR results, thus, this case was considered as having a cryptic t(15;17) translocation, three had negative BMS-D-FISH and RT-PCR results, thus, they were diagnosed as having acute myeloid leukemia rather than APL. In 9 cases with remission, one case with partial remission was found having t(15;17) translocation by CCG, and he had positive BMS-D-FISH and RT-PCR results, the other 8 patients (6 cases with normal karyotype and 2 cases without CCG examination) displayed different BMS-D-FISH and RT-PCR results: negative in 6 cases, but positive in 2 cases. The 2 cases were believed that they survived with minimal residual disease (MRD). It is concluded that BMS-D-FISH is a sensitive and reliable method for the detection of PML/RARalpha rearrangement. It is helpful for diagnosing APL and monitoring its MRD, and especially fit to those patients presenting a cryptic translocation or with failed cytogenetics, lacking suitable material for RT-PCR, as well as needing retrospective study.

An about 700 bp DNA fragment was amplified from genome DNA of S. aureus TSTw by PCR. This fragment was cloned into pGEM-7Zf(+) and the recombinant plasmid was transformed into E. coli DH5 alpha. The sequencing result of the recombinant plasmid demonstrated that it contains seb gene with 717 bp (without signal encoding region of 81 bp) which has the same nucleotide sequence as described in literature. The seb gene was cloned into expression vector 7ZTS and was transformed into E. coli JM109 (DE3). The expression level of SEB was as high as 33.3% of the cell total proteins.
