The growth and development of plant is affected by environmental factors that include light,temperature and water. Many cis-elements that are response to these elicitors interact with transcription factors, and regulate the expression of target genes. It concludes by pointing out recent studies of cis-elements and transcription factors in the plant environmental response promoters, such as light, temperature and water inducible promoter. The molecular mechanisms of gene expression regulated by environmental factors was discussed. This is important to study the mechanisms that plant adapt the environment.

OBJECTIVE To determine the functional role of hydrogen sulfide (H2S) in protecting against mitochondrial dysfunction in heart failure through the inhibition of Ca2 +/calmodulin-dependent protein kinaseⅡ (CaMKⅡ) using wild type and CSE knockout mouse models. METHODS Continuous subcutaneous injection isoprenaline (7.5 mg·kg-1·d-1), once a day for 4 weeks to induce heart failure in Male C57BL/6 (6-8 weeks old) mice and CSE-/- mice. 150 μmol·L-1 H2O2 was used to induce oxidative stress in H9c2 cells. Echocardiograph was used to detect cardiac parameters. H&E stain and Masson stain was to observation histopathological changes. Western blot was used to detect protein expression and activity. The siRNA was used to silence protein expression. HPLC was used to detect H2S level. Biotin assay was used to detect the level of S- sulfhydration protein. RESULTS Treatment with S-propyl-L-cysteine (SPRC) or sodium hydrosulfide (NaHS), modulators of blood H2S levels, attenuated the development of heart failure in animals, reduced lipid peroxidation, and preserved mitochondrial function. The inhibition CaMKⅡ phosphorylation by SPRC and NaHS as demonstrated using both in vivo and in vitro models corresponded with the cardioprotective effects of these compounds. Interestingly, CaMKⅡ activity was found to be elevated in CSE-/- mice as compared to wild type animals and the phosphorylation status of CaMKⅡ appeared to relate to the severity of heart failure. Importantly, in wild type mice SPRC was found to promote S-sulfhydration of CaMKII leading to reduced activity of this protein however, in CSE-/- mice S-sulfhydration was abolished following SPRC treatment. CONCLUSION A novel mechanism depicting a role of S-sulfhydration in the regulation of CaMKⅡ is presented. SPRC mediated S-sulfhydration of CaMKII was found to inhibit CaMKⅡ activity and to preserve cardiovascular homeostasis.

Objective To examine the expressions of FHIT gene and HER_2 in non-small cell lung cancer(NSCLC)and the relationship between the expressions and the clinicopathological features of NSCLC, and to investigate the relationship between FHIT protein and HER_2 expression. Methods FHIT protein and HER_2 expressions in 50 lung cancer cases and 21 adjacent non-cancer tissues were performed by immunohistochemistry. And the positive rates of FHIT and HER_2 were measured. Results The positive rates of FHIT protein were 30.00% in lung cancer tissues. The expression levels of FHIT were significantly lower in lung cancer tissues than that in non-cancer lung tissues (P

In this study, the 5' -flanking proximal region of stress-induced gene encoding betaine aldehyde dehydrogenase was isolated by Adaptor-PCR and TAIL-PCR from halophyte Suaeda liaotungensis. 1993 bp sequence was obtained by sequencing. The transcription start site, which localized at 62 bases upstream of the start ATG, was predicted using TSSP-TCM program. The functional elements were analysed by PLACE programm. The SlBADH gene promoter contains the basic elements: TATA-box, CAAT-box, and stress-induced elements: salt responsed element, cold, dehydration, ABA and frozen responsed elements, WUN responsed elements and HSE. Obtaining the promoter of betaine aldehyde dehydrogenase gene from Suaeda liaotungensis provides a foundation for analyzing the stress-induced promoter elements, studying the relationship between structure and founction of the promoter, and investigating the molecular mechanism of BADH gene regulation.

Piperine possesses numerous excellent and extensive pharma cological activities,such as anticancer,anti-inflammatory,antibiosis,and so on.Many researches have been reported on structural modification of piperine as a leading compound.The current review intends to introduce the research progress of chemical synthesis and biological activities of piperine derivatives concisely and illustrate the structure-activity relationship of derivatives so as to offer reference and experience for the subsequent research and development of piperine analogues.

AIMTo manage male infertility with obstructive azoospermia by means of percutaneous epididymal sperm aspiration (PESA) and intrauterine insemination (IUI).

METHODSNinety azoospermic patients with congenital bilateral absence of the vas deferens (BAVD, n=58) or bilateral caudal epididymal obstruction (BCEO, n=32) requesting for fine needle aspiration (FNA), PESA and IUI were recruited. The obstruction was diagnosed by vasography and determination of the fructose, carnitine and alpha-glucosidase levels in the seminal fluid.

RESULTSThe mean sperm motility, density, abnormal sperm and total sperm count of the caput epdidymis were 16 %+/-22 %, (12+/-31) x 10(6)/mL, 55 %+/-36 % and (16+/-14) x 10(6), respectively. In the 90 couples, a total of 74 PESA procedures and 66 cycles of IUI were performed. Three pregnancies resulted, including one twin pregnancy giving birth to two healthy boys, one single pregnancy with a healthy girl and another single pregnancy aborted at week 6 of conception. The pregnancy rate per IUI cycle was 4.5 %.

CONCLUSIONThe birth of normal, healthy infants by IUI using PESA indicates that the caput epididymal sperm possess fertilization capacity. The PESA-IUI programme is a practical and economical procedure for the management of patients with obstructive azoospermia.

OBJECTIVESThe investigation of the testicular volume, the penis length and the T, FSH, LH, PRL levels in serum were taken in 289 adolescent males to provide the valuable data for andrology.

METHODSThe adolescent males were grouped according to their age. The testicular volume was measured with testicular model and the T, FSH, LH, PRL levels in serum were determined by immunoenzymetric assay.

RESULTSThe male sexual development was rapid from age 11 to 16 and close to that of adult at age 18. Serum PRL of adolescent males was higher than that of adult males.

CONCLUSIONSThe age 11 to 16 is a period of rapid growth in sexual maturation. PRL may play an important role in sexual maturation.

OBJECTIVE: To investigate the prevalence and related factors of emotional problems of newly identified patients with HIV/AIDS in Changsha, Hunan Province, and to provide scientific evidence for the mental health intervention in this special population. METHODS: A total of 370 patients with HIV/AIDS who were newly identified by the Center for Disease Prevention and Control in Changsha City from March 1, 2013 to February 28, 2014 were investigated. Self-designed questionnaire, Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), HIV/AIDS Stress Scale and Social Support Rating Scale (SSRS) were performed to assess the prevalence of depression, the anxiety symptoms, the HIV related stress and the status of social support. RESULTS: The prevalence of depression and anxiety were 40.3% (PHQ-9 ≥ 10 points) and 30.5% (GAD-7 ≥ 10 points), respectively. Severe depressive symptoms (PHQ-9≥20 points) and severe anxiety (GAD-7 ≥ 15 points) accounted for 8.1% and 14.3%, respectively. Hierarchical regression analysis showed that the status of employment (b=-3.407, P<0.001; b=-2.799, P=0.001), the sexual orientation (b=1.903, P=0.008; b=1.314, P=0.034), the resident status (b=-1.995, P=0.012; b=-2.167, P=0.002), the emergence of HIV-related symptoms(b=4.578, P<0.001; b=3.652, P<0.001) and the HIV related stress (b=0.081, P<0.001; b=0.090, P<0.001) were the predictors for both depressive and anxious emotional problems whereas the social support (b=-0.046, P=0.044) was the predictor for depressive emotional problems. Both anxiety (ΔR2=54.7%, P<0.001) and depression (ΔR2=55.8%, P<0.001) were strong predictors for patients with HIV/AIDS. CONCLUSION Depression and anxiety are prevalent among the newly identified patients with HIV/ AIDS. Psychosocial support and basic mental health services should be integrated into the current HIV/AIDS care system.
