OBJECTIVETo observe monocyte (Mo) development in wild type C57BL/6 mice and apoE gene knockout (apoE(-/-)) mice, and to evaluate the immuno-regulatory effect of Huanglian Jiedu Decoction (HJD) on peripheral Mo development in apoE(-/-) mice.

METHODSFour, 8, 12, and 16 weeks old female C57BL/6 mice were set up as control groups of different ages, while 4, 8, 12, and 16 weeks old female apoE(-/-) mice were set up as hyperlipidemia groups of different ages. Four-week old female C57BL/6 mice were recruited as a blank group. Four-week old female apoE(-/-) mice were randomly divided into the control group, the Western medicine group, and the Chinese medicine group by paired comparison, 5 in each group. Equivalent clinical dose was administered to mice according to body weight. Mice in the Western medicine group were administered with Atrovastatin at the daily dose of 10 mg/kg by gastrogavage, while those in the Chinese medicine group were administered with HJD at the daily dose of 5 g/kg by gastrogavage. Body weight was detected each week. After 4 weeks blood lipids levels (such as TG, TC, LDL-C, and HDL-C), and the proportions of Mo and Ly6c(hi) were detected.

RESULTSCompared with 4-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05). Levels of TC and TG, and the proportion of Ly6c(hi) subtype increased, but the proportion of Mo de- creased in 8-week-old apoE(-/-) mice (P <0. 05). Levels of TC, TG, and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05). Levels of TC, TG, LDL-C, and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with 8-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05); levels of TC and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05); levels of TC and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with C57BL/6 mice of the same age, TC and TG increased, HDL-C decreased (P < 0.01) in 4-and 8-week-old apoE(-/-) mice (P < 0.01); levels of TC, TG, LDL-C increased, and HDL-C level decreased in 12- and 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01); the proportion of Mo increased in 4-week-old apoE(-/-) mice (P < 0.05); proportions of Mo and Ly6c(hi) increased in 8-week-old apoE(-/-) mice (P < 0.05). Compared with the blank control group, levels of TC, TG, and LDL-C, proportions of Mo and Ly6c(hi) increased (P < 0.01, P < 0.05), but HDL-C level decreased (P <0. 01) in the control group after intervention. Compared with the control group, body weight gained less in the Western medicine group and the Chinese medicine group (P < 0.05); the proportion of Ly6c(hi) subtype decreased in the Chinese medicine group (P < 0.05).

CONCLUSIONSIn development process blood lipids levels in apoE(-/-) mice are not only associated with age. Blood lipids levels induced growth changes in natural immune system are also correlated with age. In early stage of lipids development HJD intervention could correct this special immune disorder in apoE(-/-) mice.

OBJECTIVETo investigate the time trends of cancer mortality among residents in Kaifeng county, Henan province.

METHODSData on cancer mortality from the vital registration system in Kaifeng county from 1988 to 2005 was analyzed. A total of 9543 death records (5974 males and 3567 females) due to malignant tumors were studied. A two-year-period age-specified standardized mortality rates were directly adjusted by the world standard population, and the annual percentage change (APC) of mortality were estimated by a linear logarithm regression.

RESULTSThe crude cancer death rate for male was 95.09/100,000 and its age-standardized death rate was 117.41/100,000. While, the crude cancer death rate for female was 59.13/100,000 and the age-standardized death rate was 57.15/100,000. There was a significant growth tread for lung cancer (APC: 6.54%), liver cancer (5.07%) in males and breast cancer (7.04%) in females in the groups aged over 18. On the contrary, the decreasing treads for esophageal cancer in both of sexes (-7.09%, -13.53%) were also observed in this study. Meanwhile, there was no other significant changes in the trend, either in the tumor sites or mortality, was observed.

CONCLUSIONIn the past two decades, there has been a significant increasing trend for cancer mortality in Kaifeng county, of Henan Province. Hence, it is necessary to enhance epidemiological survey to identify risk factors at the earlier stages.

OBJECTIVETo investigate the relationship between the levels of antidesmoglein (DSG) 1, 3 antibodies in the sera of patients with paraneoplastic pemphigus (PNP) and alopecia.

METHODSSera from PNP patients, bullous pemphigoid patients, and normal healthy subjects were collected and 2 tissue samples from 2 healthy scalps were resected. Anti-DSG 1, 3 antibodies in the sera of PNP patients were detected by enzyme-linked immunosorbent assay (ELISA). Indirect immunofluorescent assay was used to detect whether the antibodies in the sera of PNP patients binds with the follicular epithelium of normal healthy scalp.

RESULTSAnti-DSG3 autoantibody was strongly positive and anti-DSG1 weakly positive in one patient, while both two antibodies were negative in the other patient. Their sera could bind to keratinocytes and follicular epithelium in human scalp. Immunofluorescent signals were found on the intercellular epidermal cell surface and outer root sheath of the follicular epithelium. However, the immunofluorescent signals in the section incubating with serum of bullous pemphigoid were only found on basal membrane zone. No signals were found in the section incubating with normal healthy serum.

CONCLUSIONAlopecia in PNP patients are correlated with the anti-DSG3.

Objective To investigate the effect of high power microwave(HPM) irradiation on neuropeptide Y (NPY) and neural nitric oxide synthase (nNOS) expression in the cerebral cortex and hippoeampus of Wistar rats. Methods A total of 110 Wistar rats were used for this study.Three groups of 30 Wistar rats were exposed to HPM irradiation at intensities of 3,10,30 and 100 mW/cm~2,respectively.Twenty rats served as controls and were ex- posed to sham HPM irradiation.At 6 h,and at 1,3,7,14 and 28 d after irradiation,five rats from each group were sacrificed,and their cerebral cortices and hippocampi were harvested.HE staining was used to highlight any change in the structure of the cerebral cortex or hippocampus.Immunohistochemistry techniques and image analysis were used to study the changes in NPY and nNOS expression.Results 10 to 100 mW/cm~2 HPM irradiation caused pyc- nosis and deep staining of some neurons in the cerebral cortex and hippocampus.The increase in nNOS expression and decrease in NPY expression observed were significant at 3 days after irradiation.Conclusion HPM irradiation can induce injury in neurons of the cerebral cortex and hippoeampus,and abnormal NPY and nNOS expression.

OBJECTIVETo investigate the quality and spatial distribution features of semen and to evaluate the reproductive health of the males in the Chongqing section of the Three-Gorge Reservoir area.

METHODSWe collected semen samples by masturbation after 2 -7 days of abstinence from the men in Nan'an, Shapingba, Zhongxian, Wanzhou, Yunyang and Wushan of Chongqing, which are geographically and demographically representative of the Three-Gorge Reservoir area. We analyzed the semen quality of all the samples and evaluated the reproductive health of the men.

RESULTSThe mean value of the five semen parameters of the male subjects from the six districts was within the normal range, including semen volume, sperm concentration, total sperm count, rapid progressive motile sperm, and total motile sperm. Those from Shapingba, Yunyang and Zhongxian exhibited abnormal sperm motility. According to the WHO criteria, normal value of all the semen parameters was found in less than 50% of the semen samples from the six districts, in 47% of those from Yunyang, and only 16% of those from Wanzhou. Spatial distribution maps of the semen parameters revealed significant spatial differences in seminal quality among the six districts, the highest in Yunyang, and the lowest in Wanzhou and Wushan that are located in the middle and lower reaches of the Three-Gorge Reservoir area.

CONCLUSIONThe mean value of semen parameters was low in a large proportion of men in the Chongqing section of the Three-Gorge Reservoir area, with spatial differences along the Changjiang river.

OBJECTIVETo investigate the renin-angiotensin system (RAS) in mesenteric adipose tissues and effect of angiotensin II on adipocyte differentiation.

METHODSThirty normal 8-week-old male Wistar rats were divided into groups on normal diet and high-fat diet. The rats on high-fat diet for 24 weeks developed the metabolic syndrome respectively. The mRNA and protein expression of mesenteric adipose tissue were measured by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. Lipid drop in 3T3-L1 preadipocytes and mature adipocytes were observed using oil-red O staining. The fluorescence microscope was used to detect cytosolic-free calcium in 3T3-L1 preadipocytes and mature adipocytes.

RESULTSThe expressions of angiotensinogen, angiotensin converting enzyme, angiotensin II receptor type 1 in mesenteric adipose tissue were significantly increased in rats with metabolic syndrome compared with those in rats on normal diet (P <0. 05, P <0. 01). After administration of angiotensin II , no lipid droplet in 3T3 -L1 preadipocytes and adipocytes were observed, however, intensive lipid droplet in adipocyte was found after administration of captopril and candesartan. Angiotensin II increased the intracellular-free calcium concentration in preadipocytes (P < 0. 01 ) , which was blocked by captopril and candesartan; in contrast, angiotensin II effect was blunt in mature adipocyte. Captopril and candesartan partially recovered the angiotensin II -mediated increase of cytosolic-free calcium.

CONCLUSIONRAS in the mesenteric adipose tissues is active in rats with metabolic syndrome, and antagonization of RAS can recover the lipogenesis of adipocyte.

This study was aimed to establish the technique of multiplex fluorescence in situ hybridization (M-FISH) and to explore its usefulness in detection of complex chromosomal aberrations (CCAs) in acute lymphoblastic leukemia (ALL). Five ALL patients with CCAs were analyzed by combining the techniques of conventional cytogenetics (CC) and M-FISH. The results demonstrated that M-FISH confirmed the aberrations previously detected by CC, such as t (9;22), t (1;19) and t (y;1), and revealed new abnormalities as der (1) (1::3::7), der (6) t (6;9) (q?;p13), der (1) t (1;11), der (12) t (1;12), der (3) t (3;5), der (2) t (2;16), der (9) (9::18::7) and der (7) (9::18::7), and also corrected the wrong results in CC. Among these abnormalities, der (9) (9::18::7) and der (7) (9::18::7) were reported for the first time. In conclusion, M-FISH has proved to be useful in characterization of the CCAs in ALL, and it is an essential method to refine the karyotype analysis.
