Objective To study the influence of carbon dioxide pneumoperitoneum on BIS and oxygen metabolism in patients underwent laparoscopic hysterectomy in propofol and sevoflurane anesthesia. Methods 100 cases undergoing laparoscopic hysterectomy were selected in the second hospital of Shandong university and were divided into group A and group B, 50 cases in each group. Group A were received propofol and group B were received sevoflurane anesthesia . The oxygen metabolism index in the two groups were compared before and after pneumoperitoneum. Results The PETCO2 of two groups at the time points after pneumoperitoneum were significantly higher than those before pneumoperitoneum (P<0.05). There was no significant difference of the SpO2 in two groups at the different time points during pneumoperitoneum, The HR and MAP of the group A were significantly lower than that of group B (P<0.05). There were no significant difference of the PETCO2、SpO2 between two groups. Bis in 2 groups maintained a stationary state before and after pneumoperitoneum. There was no significant difference in the period between the two groups. The CjvO2、Lac of two groups were significantly higher than that before pneumoperitoneum (all P<0.05).The CjvO2、Lac of two groups were significantly lower than that before pneumoperitoneum (all P<0.05). The CjvO2 of group A at 40 minutes after pneumoperitoneum were higher than that of group B (P<0.05), and the level of CERO2、Da-jvO2 were lower than that of group B (P<0.05). But there were no difference of the BIS、CaO2 and Lac between two groups. Conclusion Carbon dioxide pneumoperitoneum can affect the BIS and oxygen metabolism in patients underwent laparoscopic hysterectomy. The effect in propofol anesthesia was more significant than that in sevoflurane anesthesia.

Objective To explore optimized method of estimating 131I effective half-life(EHL) in patients with Graves' disease(GD).Methods The EHL was obtained by measuring thyroid radioactive iodine uptake (RAIU) of 126 patients (32 males,94 females,average age (38.47± 11.49) years) with GD at 4,24,48,96,120,144,168,192 and 216 h.Two-sample t test,bivariate correlation analysis and curve estimation were used for statistical analysis.Results The EHL of 126 patients was 0.5-7.5 (4.70±1.46) d.The EHL was 3.0-7.5(5.25±1.01) d and 0.5-6.0(3.24±1.52) d in group A (94 patients,without advanced peak of RAIU) and group B (32 patients,with advanced peak of RAIU),respectively,and the difference between the 2 groups was significant (t =8.499,P<0.01).The EHL had no significant correlation with RAIU4h/RAIU24h(r=-0.177,P>0.05) in group A,while it had negative correlation with RAIU4h/RAIU24h in group B (r =-0.724,P<0.01).In group A,the EHL of patients with RAIU24h/RAIU48h >100% was 3.0-7.5 (5.11 ±0.98) d,the EHL of patients with RAIU24h/RAIU48h ≤ 100% was 4.0-7.0(5.91±0.94) d (t=3.141,P<0.01).In group B,when RAIU4h/RAIU24h+RAIU24h/RAIU48h was used as the independent variable in S curve model to estimate the EHL,the result was the best (R2=0.930,F=397.22,both P<0.01,b0 =-3.038 0,b1 =9.659 4).Conclusions In order to optimally estimate EHL,patients should be grouped according to 131I turnover.In patients with advanced peak of RAIU,the EHL should be calculated by using formula of (RAIU4h/RAIU24h +RAIU24h/RAIU48h).If no advanced peak of RAIU exists,patients should be further divided according to RAIU24h/RAIU48h > 100% or RAIU24h/RAIU48h ≤100%,and the EHL mean value of each group is taken as the estimated EHL.

Objective To observe the changes of peripheral blood CD27+B cells percentage in patients with HBV-related disease of different severity and the clinical significance.Methods 20 cases of chronic viral hepatitis B,23 cases of HBV-related liver cirrhosis,21 cases of liver cancer were selected,25 cases of healthy controls in the corresponding period who had the physical examination were set as the healthy control group.The peripheral blood in the healthy controls and the patients with HBV-related disease was collected.The cellular immune level changes and CD27+ B cells percentage was detected by flow cytometry,the humoral immunity was detected by immune transmission turbidty method:IgM,IgD.Results (1)Compared with the healthy control group,CD27+B cells percentage significantly decreased in the three groups of patients with HBV-related disease [(5.16 ± 0.36) % vs.(4.52 ± 0.22) %,(2.24 ± 0.15) %,(0.58 ± 0.02) %,F =4.32,P < 0.05],and the downward trend gradually obvious as the disease degree exacerbated.nnnnn(2)IgM,IgD in the three groups of HBV related disease patients rised obviously,and the increase range became more obvious as the disease degree exacerbation(F =3.29,5.23,P =0.02,0.03).Conclusion CD27+B cells has a close relationship with HBV-related disease,and rebuilding the body's immune defense system is great importance for evaluating prognosis and the clinical guidance in HBV-related disease.

Objective To investigate the effect of humidex combined with mean temperature and relative humidity on the incidence of bacillary dysentery in Hefei. Methods Daily counts of bacillary dysentery cases and weather data in Hefei were collected from January 1, 2006 to December 31, 2013. Then, the humidex was calculated from temperature and relative humidity. A Poisson generalized linear regression combined with distributed lag non-linear model was applied to analyze the relationship between humidex and the incidence of bacillary dysentery, after adjusting for long-term and seasonal trends, day of week and other weather confounders. Stratified analyses by gender, age and address were also conducted. Results The risk of bacillary dysentery increased with the rise of humidex. The adverse effect of high humidex (90 percentile of humidex) appeared in 2- days lag and it was the largest at 4-days lag (RR=1.063, 95%CI:1.037-1.090). Subgroup analyses indicated that all groups were affected by high humidex at lag 2-5 days. Conclusion High humidex could significantly increase the risk of bacillary dysentery, and the lagged effects were observed.
