Objective:To discuss about the reasonable use of antibiotics for infection of the CNS.Method:The classification and selection as well as the combinative use of antibiotics were reviewed individually. The role of blood-brain barrier,the use of drugs through myelin and their indications were also discussed.Results:Infections of the CNS have been controlled effectively through the use of antibiotic.Conclusion:Rationally using antibiotics in the treatment of infections of the CNS can relieve the economic burden of the patients.

Objective:To study the analgesic effect of etomidate infusion for radical mastectomy in breast cancer and its effect on hemodynamics and inflammatory mediators.Methods:From August 2015 to July 2016,84 patients with radical mastectomy were divided into the observation group and the control group according to the order of admission.The observation group was given continued infusion of etomidate,the control group was given continued infusion of propofol.The visual analogue (VAS) at different time points after operation,diastolic blood pressure (DBP),systolic blood pressure (SBP) and heart rate (HR) at the time ofextubation and serum IL-2,IL-10,IL-12 levels at 72 hours after operation were compared between two groups.Results:At the time of extubation,the DBP,SBP and HR were significantly lower in the observation group than in the control group (P＜0.05).The VAS scores of observation group were significantly lower than those of the control group at 1,5,10,24 and 48 hours after operation (P ＜0.05).The serum levels ofIL-2 in the observation group was significantly higher than that of the control group (P＜0.05),IL-10 and IL-12 levels were lower than control group (P＜0.05).Conclusion:Sustained infusion of etomidate had good analgesic effect in the treatment of breast cancer patients underwent radical mastectomy with little effect on the hemodynamics and inflammatory mediators.

Objective:To systematically evaluate the effectiveness of early enteral nutrition after hepatectomy of hepatic carcinoma in China.Methods:The database such as CNKI,VIP,WANFANG DATA and CBM were searched electronically to collect the randomized controlled trials about enteral nutrition (EN) versus parenteral nutrition (PN) after hepatectomy.Meta-analyses were performed using the RvmanS.3 software.Results:Seven randomized controlled trials involving 460 patients were included.The analysis showed that the EN had significantly higher levels of albumin (WMD =1.17,95％ CI:0.45 ～ 1.89,P =0.001) and lower levels of aminotransferase (WMD =-3.95,95 ％ CI:-7.08 ～-0.81,P =0.O1) than those in the control group.The time of gastrointestinal function recovery in EN group was shorter than that in PN group.There was no significant difference in body weight and adverse reactions of gastrointestinal tract.Conclusion:Early enteral nutrition support for patients after hepatectomy of hepatic carcinoma shows certain advantages,which can improve the nutrition status and be in favor of the recovery of liver and gastrointestinal function.

To observe the incidence of high intraocular pressure ( lOP ) and its risk factors in the early stage (within 7d) after 23 - gauge sutureless microincisional vitrectomy.
●METHODS: Retrospective case series study. Totally 98 patients ( 98 eyes ) who had undergone 23 - gauge sutureless microincisional vitrectomy were enrolled. lOP was measured by non-contact tonometry. High lOP was defined as an lOP > 25mmHg at any time within 7d after surgery. The influence of age, sex, side of operation, course of disease, primary disease pre - operation, reoperation, surgical options, type of tamponade, status of lens, surgical time on postoperative high lOP were analyzed.
● RESULTS: High lOP was found in 33 eyes ( 33. 7%) within 7d after surgery. High lOP was found in 8 eyes on postoperative 1d, the incidence was 24. 2% (8 / 33), and 25 eyes was found on postoperative 3d, the incidence was 75. 8% (25 / 33). The incidence of high lOP of male and female were 32. 8% ( 20 / 61 ) and 35. 1% ( 13 / 37 ) respectively. The incidence of high lOP of right and left eye were 36. 8% (21 / 57) and 29. 3% (12 / 41) respectively. There were no significant differences comparing age (Z =-0. 22), sex( χ2 = 0. 057), side of operation( χ2 = 0. 612), course of disease (Z= -0.079) and surgical time (Z= -0. 553) between patients with high lOP and those without it (P>0. 05). Similarly, no statistical significance was found between eyes with gas tamponade and silicone oil tamponade (χ2 = 1. 04), traumatic eyes and non traumatic eyes(χ2 = 0. 044), and retinal detachment eyes and without retinal detachment eyes ( χ2 = 2. 282, P > 0. 05 ). The incidence of high lOP in eyes with several operations was higher than that in eyes with the first operation ( χ2 =5. 211,P< 0. 05), in eyes with combined operations eyes was significantly higher than that in eyes with pure vitrectomy (χ2 = 4. 57,P< 0. 05), and in eyes with aphakic eye was higher than that in eyes with phakic eyes ( χ2 =4. 224,P<0. 05).
●CONCLUSlON:High lOP occurs commonly in 3d after 23- gauge sutureless microincisional vitrectomy. The risk factors of high lOP are reoperation, combined operations and aphakic eye.

liver cells. The thermosensitivity of the normal rabbit hepatocyte was higher than that of biliary epithelial cells to radiofrequency ablation. Apoptosis was correlated to the thermal effect induced by RFA.

AIM: To investigate the relationship between the protective effect of sodium oxybate on neuronal damage induced by hypoxia reoxygenation and GABA A receptor in primary cultured rat cortical neurons. METHODS: The primary cultured rat cortical neurons were used to make the hypoxia reoxygenation damage model. The morphology of cell was observed. The lactate dehydrogenase (LDH) effluxed into the media as an indicator of neuronal injury was detected after 6 h of the reoxygenation injuries. The malonyldialdehyde (MDA) contents, superoxide dismutase (SOD) and glutathione peroxidase (GPX) activities were determined at the same time. RESULTS: The hypoxia reoxygenation caused neuronal swelling and widespread neuronal degeneration, increased LDH efflux and MDA contents, and decreased SOD and GPX activities. Sodium oxybate assuaged neuron damage, decreased LDH efflux and MDA contents (P

Objective: To evaluate the relationship between air pollutants and mortality of residents in Huairou District, Beijing, providing a basis for the formulation of air pollution control measures. Methods : The data of daily deaths, meteorological factors and air pollutants in Huairou District from 2014 to 2018 were collected from Beijing Disease Prevention Monitoring Information Integration and Analysis System, Huairou Meteorological Bureau and Environmental Monitoring Station. The generalized additive models were used to analyze the relationship between the average daily concentration of air pollutants and the daily deaths. Results: The medians of daily average concentrations of SO2, NO2, CO, O3, PM10 and PM2.5 were 5.00 μg/m3, 24.00 μg/m3, 0.71 mg/m3, 77.27 μg/m3, 64.25 μg/m3 and 44.13 μg/m3, respectively. Except for O3, the daily average concentrations of SO2, NO2, CO, PM10 and PM2.5 showed decreasing trends from 2014 to 2018. An increase of 10 μg/m3 of NO2 resulted in an elevation of 1.69% ( 95%CI: 0.31%-3.08% ) , 3.31% ( 95%CI: 1.24%-5.42% ) and 3.31% ( 95%CI: 0.51%-6.19% ) for non-accidental death in the whole population, females and people under 65 years old, respectively, with a delay of 2 days (lag2). For every 10 μg/m3 increase in the daily average concentrations of CO and PM2.5, the risk of non-accidental death among people under 65 years old at lag2 increased by 0.08% ( 95%CI: 0.01%-0.14% ) and 0.88% ( 95%CI: 0.12%-1.64% ) , respectively. For every 10 μg/m3 increase in daily average concentration of O3, there was 0.69% ( 95%CI: 0.02%-1.36% ) increase in daily male non-accidental death risk at lag4. The results of the multi-pollutant model showed that after adjusting the effects of the other two air pollutants, NO2, CO and PM2.5 had no statistically significant effects on the daily non-accidental deaths of people under 65 years old at lag2 ( P>0.05 ) . Conclusion The ambient NO2, CO, O3 and PM2.5 pollution increase daily non-accidental deaths, which shows a lag effect．
