AIM:To investigate the effect of bone morphogenetic proteins 9 (BMP9) on the migration and in-vasion abilities of human lung squamous-cell carcinoma NCI-H520 cells and its mechanism.METHODS:The expression of BMP9 at mRNA and protein levels in the NCI-H520 cells and human bronchial epithelial ( HBE) cells was detected by RT-PCR and Western blot.The NCI-H520 cells were transfected with the recombinant adenovirus AdBMP9 and the expres-sion of BMP9 at mRNA and protein levels was validated by RT-PCR and Western blot.The migration and invasion abilities of the NCI-H520 cells were determined by wound-healing and Transwell assays.The mRNA and protein levels of the migra-tion-related factor matrix metalloproteinase 2 (MMP2) were detected by RT-PCR and Western blot.The level of phospho-rylated Smad1/5 (p-Smad1/5) was detected by Western blot.Meanwhile, NCI-H520 cells were treated with BMP specific antagonist AdNoggin and AdBMP9.The level of p-Smad1/5 and the cell migration ability were measured by Western blot, wound-healing and Transwell assays.RESULTS:The expression of BMP9 at mRNA and protein levels was lower in NCI-H520 cells than that in HBE cells.After AdBMP9 was stably transfected into the NCI-H520 cells, the expression of BMP9 at mRNA and protein levels was significantly up-regulated, cell migration and invasion abilities were significantly de-creased, and the mRNA and protein levels of MMP2 were decreased.Meanwhile, the level of p-Smad1/5 was increased. Noggin reversed BMP9-caused the increase in p-Smad1/5 and the decrease in cell migration ability.CONCLUSION:O-ver-expression of BMP9 inhibits the migration and invasion abilities of lung squamous-cell carcinoma NCI-H520 cells.The activation of BMP-Smad signaling pathway may be involved in this inhibitory process.

Steroid receptor RNA activator ( SRA) is a type of long non-coding RNA ( lncRNA ).The abnormal transcription of lncRNA -SRA were detected in the uterine , ovarian and breast , and the lncRNA-SRA level in breast cancer is higher than that of general population.LncRNA-SRA expression may serve as a new prognostic marker for patients with ER-positive breast cancers.Thus, elucidating the molecular mecha-nisms of lncRNA -SRA is important to develop novel proper strategies using target lncRNA -SRA in the diagnosis and treatment of breast cancer.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.

OBJECTIVETo comprehensively analyse and evaluate the risk factors and to predict the trend of breast cancer in China.

METHODSCollecting the articles on case-control studies related to breast cancer in the last 10 years in China. Calculating the relative risk (OR) and 95% confidence interval (95%CI) of risk factors by the random effect model of Meta-analysis to estimate present and future population attributable risk percent (PARP) based on the exposure rate of risk factor and to predict the change of incidence rates of breast cancer during the following 5 years with the change of exposure rates.

RESULTSTwenty-two articles referred to case-control studies on breast cancer were selected. The OR and its 95%CI of the first 5 risk factors of breast cancer in China were benign breast lesion 3.39 (2.97 - 3.86), psychological stimulation 2.36 (2.09 - 2.67), breast-feeding 1.95 (1.54 - 2.47), family history of tumor 1.84 (1.63 - 2.08) and menstruation 1.65 (1.44 - 1.89). The factors with higher PRAP were benign breast lesion, breast-feeding, psychological stimulation with PRAR 15.47%, 15.17%, 13.76%, respectively. Their PRAP would have decreased to 12.77%, 11.32%, 12.52% and 9.90%, 8.74%, 9.69% respectively if the exposure rates had decreased 20% and 40% in the next 5 or 10 years. Factors contributing to the change of incidence rate of breast cancer would include benign breast lesion, breast-feeding, psychological stimulation along with the change of exposure rate. The incidence rates of breast cancer would then have become 3.09%, 2.75%, 3.03% and 6.19%, 5.50%, 6.07% respectively if their exposure rate had decreased 20% and 40% in the next 5 or 10 years.

CONCLUSIONDecreasing benign breast lesion, avoiding psychological stimulation, advocating on breast-feeding seemed to be the effective measures to control the occurrence and development of breast cancer.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.

This study was aimed to investigate 6 kinds of human cytokines (IL-2, IL-4, IL-12, IL-13, IFN-gamma and TNF-alpha) in patients with acute lymphocytic leukemia (ALL), so as to find their relationship with the disease. The pure monoclonal antibodies were spotted on the prepared NC membrane glass slides under certain conditions to make human cytokine protein microarray. The serum samples were collected from peripheral blood of 28 patients and 25 normal controls, the serum concentration of cytokines was determined by using the protein microarray and ELISA. The results showed that the expression levels of IL-4, IL-12, IL-13, IFN-gamma and TNF-alpha in ALL patients were lower than those in the normal controls, but ELISA indicated that the expression of TNF-alpha in ALL patients and normal controls was negative. In conclusion, both cellular and humoral immunity are all inhibited in patients with ALL. Microarray is more sensitive than ELISA.

OBJECTIVEIn order to improve the irrigation for Panax notginseng growing seedlings, different mulching ways were carried out to investigate the effects of double mulching.

METHODField experiment was applied to study soil moisture, soil temperature and bulk density of different mulching ways while the germination rate and seedlings growth also were investigated.

RESULTCompared with the traditional single mulching with pine leaves or straw, double mulching using plastic film combined with pine leaves or straw could reduce 2/3 volumes of irrigation at the early seedling time Double mulching treatments didn't need to irrigate for 40 days from seeding to germination, and kept soil moisture and temperature steady at whole seedling time about 30% and 9.0-16.6 degrees C, respectively. The steady soil moisture and temperature benefited to resist late spring cold and germinate earlier while kept germination regularly, higher rate and seedlings quality. In contrast, single mulching using pine leaves or straw had poor soil moisture and temperature preserving, needed to irrigate every 12-day, meanwhile dropped the germination and booming time 14 days and 24-26 days, respectively, reduced germination rate about 11.3%-8.7%. However, single pine leaves mulching was better than straw mulching. In addition, though better effects of soil moisture and temperature preserving as well as earlier and higher rate of germination with single plastic films mulching had, some disadvantages had also been observed, such as daily soil temperature changed greatly, seedling bed soil hardened easily, more moss and weeds resulted difficulty in later management.

CONCLUSIONTo the purpose of saving water and labor as well as getting higher germination rate and seedlings quality, double mulching using plastic films combined pine leaves at the early time and single mulching removing plastic films at the later time is suggested to apply in the growing seedlings of P. notoginseng.
