1.The regulation of Cathepsin B on cell apoptosis induced by SAHA in breast cancer cell line MCF-7
Chinese Pharmacological Bulletin 2016;32(8):1086-1090
Aim To clarify the regulation role of ca-thepsin B ( Cat B ) in cell proliferation and apoptosis induced by SAHA in ER-positive breast cancer cell line MCF-7.Methods MTT was used to screen the optimal concentration and treatment time of SAHA . The expression levels of related proteins were deter-mined by ELISA , and the morphological changes were observed through time-lapse live cell imaging acquisi-tion.Cell viability and apoptosis assay in MCF-7 cells were assessed by Muse Cell Analyzer with SAHA and /or Cystatin C treatment .Results MTT assay showed that the anti-tumor efficacy of SAHA was significant . The optimal concentration and treatment time were 10μmol? L-1 and 24 h respectively . ELISA assay showed that SAHA could induce expression of Cat B in MCF-7 cells.Real-time live-cell imaging experiments demonstrated that the combination treatment of Cystatin C and SAHA significantly resumed the inhibitory effect caused by SAHA alone .Cytology test showed that SA-HA alone obviously depressed the cell viability and in-duced apoptosis . However , the effect was reversed with the combination of Cystatin C .Conclusion Cat B plays an important role in apoptosis induced by SAHA in ER +breast cancer cells MCF-7.

Objective To assess the effects of caffeine use in apnea of prematurity (AOP) in the early stage (caffeine was used within 3 days after birth) versus late stage (caffeine was used 4 to 10 days after birth ) . Methods Medline, Science Direct, Elsevier, Embase, CBMdisc and Wanfang databases were retrieved to incorporate studies that met the inclusion criteria. The retrieval time limit was from the establishment of the databases to November, 2015. References that were in line with the inclusion criteria were selected and relevant conference data were collected by manual retrieval. Two researchers conducted meta-analysis using software RevMan 5. 2 after independent data selection, information extraction and quality evaluation according to the inclusion and exclusion criteria. Results One randomized controlled trial and four retrospective cohort studies were included. A total of 59 288 patients were involved. Meta-analysis suggested that, compared with caffeine use in the late stage, the early stage group showed significant lower incidence ( P < 0. 05 ) of mortality, bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity and surgical intervention of patent ductus arteriosus. No significant difference (OR = 0. 98, 95% CI 0. 72 - 1. 33, P = 0. 881) was observed between the 2 groups in terms of the incidence of necrotic enterocolitis. Conclusions Patients with AOP should start caffeine treatment as early as possible, which significantly decreases mortality rate and the occurrence of other complications with little adverse reactions and good clinical tolerance.

Objective To evaluate the association between stress hyperglycemia and clinical out-comes among patients with and without diabetes mellitns admitted to medical intensive care unit (MICU).Methods We reviewed the medical ICU records of 1016 consecutive patients admitted to Wu Han Univer-sity Ren Min Hospital. According to admission glucose level, 126 patients with debates and 890 patients without known debates were divided into group 1 ( <6 mmol/L), group 2(6 ~ 8mmol/L), group 3(8 ~10mmol/L), and group 4( > 10mmol/L). The primary end point of the study was in-hospital mortality. Secondary end points included length of hospital stay, length of ICU stay, the ratio of mechanical ventila-tion, blood transfusions, antibiotics and blood glucose treatment. Results The hospital mortality among patients without a history of diabetes mellitus was 4. 7%, 12. 1%, 20. 5%, 30. 3% in group 1, 2, 3, 4,respectively. The ratio of mechanical ventilation, blood transfusions, and antibiotics increased progressively as glucose values increased. Conclusions Hyperglycemia was a common disease, and it may be an impor-tant marker of poor clinical outcome and mortality in patients without history of diabetes.

OBJECTIVE To investigate the influence of noise on the hearing of the workers with noise exposureand explore the relationship between the hearing damage and the length of noise exposure.METHODS 120 workers who exposed to noise were recruited. Their physical examination including audiometry was done in our hospital from year 2012 to 2014. Hearing loss and the length of noise exposure were detected in all subjects after 2-year's follow-up.The rate of hearing loss between workers with different length of noise exposure was analyzed statistically. RESULTS There were 22 workers who were exposed to noise for 2 years, 43 workers for 3-5 years and 55 workers for 6-10 years. After 2-year's follow up, there were significant differences between the rate of hearing loss and the length of noise exposure at 3,4 and 6 kHz. And the rate of hearing loss at different sound frequency were significantly different statistically. CONCLUSION The relevance ratio of hearing loss in long noise-exposed group was significantly higher than short groups. The hearing damages at 4 KHz were more frequent than other sound frequency.
