Objective To evaluate the prognostic role of bispectral index (BIS) monitoring in patients after cardiopulmonary resuscitation (CPR) in the intensive care unit (ICU).Methods Thirtythree adult patients after CPR were enrolled and divided into survived group and non - survived group as per 7-day survival.During their stay in the ICU,BIS and SaO2 (saturation of artery oxygen) levels of all the patients were continuously monitored.The neurological status of the patients was measured with Glasgow coma scale (GCS).Acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) was used to evaluate the patient condition. SjO2 (saturation of jugular bulb venous oxygen ) levels of 23 patients were continuously monitored and then the difference in values between SaO2 and SjO2 was calculated to show oxygen metabolism in the brain. The studied variables were compared between the two groups. The correlations between BIS values and GCS scores,and between BIS and APACHE Ⅱ scores were respectively analyzed. Results The BIS values and difference in values between the SaO2 and SjO2 were significantly higher in the patients of survived group than those in the patients of non-survived group (P ＜0.01 ).There were positive correlation between BIS and GCS (r =0.821,P ＜ 0.01 ) and as well as positive correlation between BIS and APACHE- Ⅱ ( r =0.434,P ＜ 0.05 ).Conclusions The BIS may be useful to predict the post - resuscitative outcome of patients after cardiopulmonary resuscitation.

The variation of blood glucose in 1 147 patients with type 2 diabetes mellitus was monitored by continuous glucose monitoring system(CGMS). The results showed that the peak hours of nocturnal hypoglycemia occurred during 22 : 00-2 : 00. The incidence of nocturnal hypoglycemia was negatively correlated with mean blood glucose and blood glucose at three hours after supper. The probability of hypoglycemia was up to 50% when blood glucose level had been as low as 4. 7 mmol/L at 3 h after supper.

Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Aim To establish ICR animal model with C6 glioma stem cells, to provide the ideal model for the further study of gli-oma stem cells in brain glioma model. Methods C6 glioma stem cell was cultured in vitro by suspension,and was identified with Nestin antibody. C6 stem cells of ICR mouse glioma model were used to investigate survival state and tumor volume in mice after the operation. HE staining and CD133 immunohistochemi-cal study were adopted to investigate the postoperative pathologi-cal changes in mice. Results The expression of Nestin was 96. 01% in C6 glioma stem cells, and Nestin was highly ex-pressed in the cultured C6 glioma stem cells. Mice were inocula-ted with tumor after loss of appetite, weight, behavior and slow, sluggish reaction. Tumor volume at day 21 after modeling was (9. 77 ± 6. 58) mm3 . After HE staining, the model showed the invasive growth, tumor cell shrinkage and derangement. Immu-nohistochemical CD133 staining revealed that tumor cytoplasm color was brown. Conclusion Glioma model can be established based on glioma stem cells into a high rate of tumor, the tumor cycle is short, which can be used as an ideal model for glioma.

Background Neurofilament 200 (NF200) is an indirect indicator of the specific distribution of axons.It reflects the condition of the maintenance of neuronal morphology.Whether NF200 is involved in the damage of the visual pathway after retinal ischemia reperfusion injury (RIRI) should be further examined.Objective The present study was to investigate the expression of NF200 in retinal ganglion cells (RGCs),lateral geniculate nucleus (LGN),superior colliculus and visual cortex following RIRI.Methods Forty SD rats were randomized into the RIRI 1-,2-,3-,4-,6-,8-week groups,sham operation group and control group.Acute intraocular hypertension was induced in the right eye by anterior chamber perfusion of normal saline solution for 60 minutes to elevate the intraocular pressure to 110 mmHg.The animals were sacrificed at different time points for the preparation of the retina,LGN,superior colliculus and visual cortex sections.The expression of NF200 in RGCs,LGN,superior colliculus and visual cortex was assayed by immunohistochemistry.Results The expression level (A value) of NF200 in the RGCs was significantly different among the 8 groups after reperfusion (F =78.855,P =0.000),and that in the 1-week group was significantly lower than in the control group (t =36.563,P＜0.01).In the RIRI 1-week group,the expression of NF200 in the contralateral LGN in the experimental group was significantly lower than that in the control group (t =6.483,P＜0.01).In the 4-week group and 6-week group,the expression of NF200 in the contralateral LGN was significantly higher than that in the control group (t =2.904,4.313,P＜0.01).One week after RIRI,the expression of NF200 in contralateral superior celliculus in the experimental group was significantly lower than that in the control group (t =2.966,P＜0.05),and in the 2-week group,the expression of NF200 in the contralateral superior colliculus was significantly higher than that in the control group (t =7.397,P＜0.01).In the 2-week group,3-week group and 4-week group,the expression of NF200 in bilateral visual cortex was significantly higher in the experimental group than that in the control group (contralateral ∶ t =18.728,18.213,15.088,P＜0.01 ; ipsilateral ∶ t =8.690,5.704,7.805,P＜0.01).Conclusions RIRI can induce axonal damage of RGCs,contralateral LGN,superior colliculus and bilateral visual cortex neurons.

OBJECTIVETo explore the clinical efficacy and action mechanism of acupuncture for premature ovarian failure (POF).

METHODSAccording to prospective cohort study design, 30 cases were included. Based on theory of regulating Chong and Conception Vessels as well as soothing the liver and calming the nerves, acupuncture at Guanyuan (CV 4), Dahe (KI 12), Taixi (KI 3), Taichong (LR 3), Baihui (GV 20) was applied, three times per week and 3 months were considered as one session. Totally two sessions were performed. The menstruation condition, estradiol (E2), follicle-stimulating hormone (FSH) and scores of the clinical perimenopausal symptoms were taken as treatment outcomes.

RESULTSThe total effective rate was 86.7% (26/30) and the cured rate was 16.7% (5/30). The recovery rate of menstruation was 16.7% (5/30) and the regain rate of menstruation was 56.7% (17/30). After the treatment, the level of E2 was significantly increased from (45.41 +/- 18. 09) pmol/L to (59.07 +/- 24.21) pmol/L (P < 0.05), and the score of perimenopausal symptoms was obviously reduced from 14.28 +/- 8. 30 to 4.04 +/- 3.28 (P < 0.01). However, no statistical differences could be seen in FSH before and after treatment (P > 0.05).

CONCLUSIONAcupuncture has certain effect on improving menstruation and perimenopausal symptoms in POF patients, which is likely to he related with increasing the level of E2.

In the process of vinification, the metabolic products of various yeasts are key to the sensory characteristics. Different species produce different volatile composition, which results in direct influences on wine's bouquet mostly. Metabolic characteristics of Saccharomyces and non-Saccharomyces and the different influences on odour by them as well as interactions among various species were described in this paper. Research progress on non-Saccharomyces was summarized.Studies confirmed that some characteristics of non-Saccharomyces play a positive role in the structure of bouquet of wine. Combined use of Saccharomyces and some of non-Saccharomyces will be beneficial to sensory characteristics of wine.
