Objective To explore the effects of chronic fluorosis on neurons in the cerebral cortex of rats,and to provide some morphological evidence of damage in the central nervous system induced by chronic fluorosis.Methods Male Wistar rats 40 days after birth were fed with high fluoride contented water(100 mg/L)for inducing chronic fluorosis.Immunocytochemistry and in situ hybridization were used to detect c-fos and Caspase 8 at cerebral cortical neurons respectively.Results c-fos positive cells rate and gray scale in the cerebral cortex of chronic fluorosis were 35.8%and 0.2756±0.0241,respectively,and that of control group were 32.1%and 0.2774±0.0331with statistical difference(χ2=0.305,t=0.826,P＞0.05).Caspase 8 positive cells rates of fluorosis group and control group were 18.7%and 14.1%,respectively,the difference being statistically significant(χ2=0.419,P＞0.05).The gray scale of fluorosis group and control group were 0.3874±0.0329 and 0.3884±0.0323,respectively,the difference being statistically significant(t=0.641,P＞0.05).Conclusion Chronic fluorosis had no significant influence on apoptosis of cerebral cortical neurons.

Objective To understand the status and administration of Young Scholar Scientific Research Program at China CDC,to analyze the program functioning and raised problems,as well as further discuss administrative strategies internally at institutional level.Methods To review and analyze the archived documents and data materials of Young Scholar Scientific Research Program at China CDC.Results Department of Science and Technology is responsible for the daily management of Young Scholar Scientific Program.The research fields of these projects mainly focused on public health and infectious disease.75 two-year period projects are funded and 55 have been completed so far.Accumulated subsidy amount is up to 6.68 million RMB.146 papers have been published,among which 57 English papers have been published (47 were in SCI journals).And 5 patents were granted.Conclusions The establishment of the Young Scholar Scientific Program has empowered the young fellows for conducting scientific research independently.On the other hand,this program also strengthened technical support for disease prevention and control.It is proposed to go on strengthen the scientific management and further establishing academic communication plat form for young fellows.

?Advances in genome-wide analysis have revealed that up to 90%of the human genome is transcribed.However, only approximately 1% of RNA transcripts encode proteins, and the remaining transcripts are noncoding RNAs.Noncoding RNAs can be roughly divided into small noncoding RNAs (<200nt ) and long noncoding RNAs ( LncRNAs, >200nt ). Small noncoding RNAs include microRNAs, transfer RNAs and small nucleolar RNAs, whereas the long noncoding RNAs comprise ribosomal RNA, natural antisense transcripts, etc. Although the biosynthesis and biological activities of microRNAs are well studied through bioinformatics and active biological molecules analysis, the understanding of LncRNAs on these aspects is still limited.LncRNAs play multiple roles in regulating gene transcription and translation, and epigenetics.Aberrant LncRNAs expression can occur in various pathological processes and significantly related to the pathogenesis or poor prognosis of ophthalmological diseases. In this review, we will focus on the characteristics and regulatory functions of LncRNAs that are commonly associated with ophthalmological diseases.

OBJECTIVETo investigate the effect of Fructus psoraleae on the differentiation of cultured osteoblast MC3T3-E1 cell isolated from neonatal mouse's calvarium.

METHODF. psoraleae preparation was extracted with distilled water. A mouse osteoblast cell line MC3T3-E1 was used as a cell model for screening potency. Cultured MC3T3-E1 osteoblasts were divided into 4 groups: control and F. psoraleae extract 0.02, 0.2, 2 (crude drug) g x L(-1), change the medium and extract every 3 days. The content of ALP and type I collagen were measured. The expression of ALP, type I collagen and osteocalcin mRNA in MC3T3-E1 cell was detected by real-time PCR.

RESULTThe activity of ALP was stimulated by extract of F. psoralea at doses 0.2 g x L(-1), and the content of type I collagen was encouraged at doses 0.2 g x L(-1) . The extract of F. psoralea enhanced the expression of ALP, type I collagen and osteocalcin mRNA in MC3T3-E1 cell. The expression of ALP mRNA was enhanced by extract of F. psoralea at doses 0.2 g x L(-1) for 7-14 d, and the expression of type I collagen and osteocalcin mRNA was enhanced at doses 0.2 g x L(-1) for 14-21 days.

CONCLUSIONF. psoralea can stimulate the differentiation of osteoblasts in vitro. It will offer a reference for the active mechanism research.

OBJECTIVETo observe analgesic and sedative effect of acupuncture combined with medicine (ACM) on patients undergiong cardiac surgery.

METHODSA total of 50 patients with cardiac surgery from January 2012 to October 2014 were randomly assigned to the conventional analgesia group (group A) and the ACM analgesia group (group B), 25 in each group. Patients in group A were subjected to analgesia and sedation by injecting dexmedetomidine, while patients in group B were subjected to analgesia and sedation by electro-acupuncture [EA, Shenting (GV24); Yintang (EX-HN3)] combined with injection of dexmedetomidine. Morphine hydrochloride injection was performed when analgesia and sedation effect was ineffective in the two groups. The indicators of patients at different time points in the two groups were observed, such as static and dynamic VAS scores, SAS scores, mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2). The injection dosage of dexmedetomidine and morphine hydrochloride, analgesia satisfaction rate, sedation satisfaction rate, the incidences of adverse reactions during treatment such as bradycardia and low blood pressure, mechanical ventilation time, ICU time, and hospitalization expense were observed and recorded in the two groups.

RESULTSThere was no statistical difference in static and dynamic VAS scores, SAS score, MAP, HR and SpO2 between the two groups at different time points (P > 0.05). The injection dosage of dexmedetomidine and morphine hydrochloride was significantly reduced in group B than in group A (P < 0.05). The analgesia satisfaction rate of patients in group B was much higher than that in group A (P < 0.05). The incidence of bradycardia also obviously decreased more in group B than in group A (P < 0.05). There was no statistical difference in patients' sedation satisfaction rate, incidences of low blood pressure, delirium, vomiting; mechanical ventilation time, ICU time, or hospitalization expense between the two groups (P > 0.05).

CONCLUSIONThe analgesia method of ACM could reduce the dosage of traditional analgesic drugs and the occurrence of partial adverse reactions.

OBJECTIVETo observe the changes of electrocardiogram (ECG) and pregnancy outcome of the late pregnancy women.

METHODSLate pregnancy women were divided into two groups by age: over 35 group and under 35 group. The incidence of abnormal electrocardiogram was recorded when the patients were subjected to routine ECG examination. Then the pregnancy, delivery outcome and if there's low birth weight newborn were recorded later.

RESULTSThe incidence of abnormal ECG in over 35 group was significantly higher than that in under 35 group (P < 0.05). And the incidence of ST segment changes, arrhythmia in the group of former was higher than that in the group of latter (P < 0.05). Among the different type of arrhythmia, the incidence of sinus bradycardia and ventricular premature beat in the group of former were higher than those in the group of latter (P < 0.05). But the incidence of sinus tachycardia in the former group was obviously lower than that in the latter group (P < 0.05). The incidence of pregnancy loss in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal or abnormal ECG groups (P < 0.05). The incidence of premature birth in over 35 with abnormal ECG group was significantly higher than that in over 35 with normal ECG group (P < 0.05). The incidence of low body weight in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal ECG group (P < 0.05).

CONCLUSIONThe late pregnancy women with the age of over 35 are more likely to have ECG abnormalities, such as arrhythmia, myocardial ischemia and so on. The older pregnant women with abnormal ECG easily suffer from pregnancy losing, premature birth and having a low birth weight baby.
