Objective: To investigate effects of different frash gas flow of oxygen ventila-tion on emergence time and delirium undergoing Enflurane general anesthesia. Methods: Forty- eight patients, ASA Ⅰ- Ⅱ, aged 33- 68yr, mean 50.5yr, underwent elective abdominal op-eration were randomly divided into three groups according to the different frash gas flow at the end of operation: GroupⅠ, the flow of oxygen maintained at 2 L/min, GroupⅡ 4 L/min, GroupⅢ 10 L/min. Anesthesia was induced with intravenous midazolam 0.08- 0.1mg/kg, etomidate 15- 20mg,fentanyl 3- 4 ?g/kg, pipecuronium 0.08- 0.1mg/kg and maintained with Enflurane(1.5- 2.0vol%), supplemented with intermittent iv pipecuronium and fentanyl. The concentration of Enflurane was monitored continuous which involved Fi, Fa and Fao, originated from inspiration, expiration and the moment expiration when stopped inhalation. Accounted Fao and after this detailed every one minute Fa until the patients recovery and calculated Fa/Fao ratio. Emergence time was recorded. Mini- Mental State Examination (MMSE) was performed before anesthesia and after surgery. Results: Fa/Fao ratio in GroupⅠ was significantly defferent from GroupⅡ and Ⅲ. MMSE scores in GroupⅠwere higher compare with GroupⅡand Ⅲ after surgery. Emergence time was no signif-icantly difference among three groups. Conclusion : The frash gas low flow of oxygen ventila-tion might reduce the incidence of delirium,but does not influnce the time of emergence from general anesthesia.

Objective To explore the effects of exogenous glutathione on arsenic distribution and nitric oxide (NO) metabolism in the brain of mice exposed to arsenite through drinking water. Methods Female Kunming mice were randomly divided into 5 groups, eight in each, and the mice were exposed to sodium arsenite through drinking water at doses of 0 mg/L (control) and 50 mg/L arsenic for 4 consecutive weeks, on the fourth week, with the exposure of arsenic, glutathione was given through intraperitoneal injection at doses of 200 mg/kg b.w, 400 mg/kg b.w or 800 mg/kg b.w, respectively for 7 days. In the end of treatment, the samples of blood and brain were collected. Levels of inorganic arsenic (iAs), monomethylarsonic acid (MMA) and dimethylarsenic acid (DMA) were determined by HG-AAS method. Activities of nitric oxide synthase (NOS) and the concentrations of NO were determined with kits. Results Compared with those in single arsenic group, glutathione significantly decreased levels of iAs, MMA and total arsenic levels (TAs) in the blood and levels of DMA and TAs in the brain. Activities of NOS and levels of NO in As group were significantly lower than those in control, however administration of glutathione could ameliorate these toxic effects, and NOS activities in groups treated with 400 mg/kg b.w and 800 mg/kg b.w glutathione were significantly higher than those in single arsenic group. Conclusion Exogenous glutathione may promote methylation of arsenic, therefore reduce arsenic levels in both blood and brain. Moreover, it is proposed that administration of exogenous glutathione can ameliorate the adverse effects of arsenic on NO metabolism in the brain via decreasing the brain arsenic burden.

Radiation-induced cognitive impairment is hypothesized to occur because of dynamic interactions be -tween multiple cell types, including astrocytes, endothelial cells, microglia, neurons, and oligodendrocytes.Cur-rent researche indicates that radiation-induced changes include the decrease in hippocampus neurogenesis , altera-tions of neuronal functions , particularly synaptic plasticity , as well as the elevation of neuroinflammatory cytokines .

Methods The plasma D‐dimer level was detected in 78 individuals of healthy physical examination(healthy control group) and 82 patients with acute cerebral hemorrhage .Results The plasma D‐dimer levels at admission(0 h) had no statistical difference among various groups(P> 0 .05) ;the D‐dimer level at 24 ,48 ,72 h in the small cerebral hemorrhage group was significantly higher than that in the healthy control group(P< 0 .05) ;the D‐dimer level in the massive cerebral hemorrhage group was significantly higher than that in the small cerebral hemorrhage group(P< 0 .05) ;the D‐dimer level in the small cerebral hemorrhage group reached the peak at 24 h ,while which in the massive cerebral hemorrhage group reached the peak at 48 h and was positively correlated with the intracranial hemorrhage volume(r= 0 .914 ,P= 0 .000 < 0 .05) .Conclusion The plasma D‐dimer level in the patients with acute cer‐ebral hemorrhage is obviously increased and shows the increasing trend with the intracranial hemorrhage volume increase ;the more the intracranial hemorrhage volume ,the longer the persistence time of high D‐dimer level .Therefore detecting plasma D‐dimer level has an important significance for monitoring the condition in the patients with acute cerebral hemorrhage .

Elemene is a new anticancer drug isolated from a Chinese traditional medicine Curcuma aromatica. In previous work, we discovered that tumor cell vaccine (TCV) treated with oleum Curcuma aromatica or elemene could induce significant immunoprophylactic effect against a variety of aminal tumor strains and the method of preparation of elemene combo-TCV(EC-TCV) already got China's inventive patent. In this paper we further studied the active immunotherapeutic effect and the possible cellular/molecular mechanisms of EC-TCV immunization. The results were as follows:(1) EC-TCV immunization showed significant therapeutic effects (P＜0.05) against murine Ca761 syngeneic mammary carcinoma (H-2k) and HCa-F allogeneic hepatic carcinoma (H-2-) models; (2) The spleen cells of Hca-F EC-TCV immunized mice displayed higher cytotoxicity and IL-12 level while the secretion of IL-10 was decreased (P＜0.05); (3) Similar to heat shock, elemene(E), mitomycin C(MMC) and glutaraldehyde (G) could act alone as stressor, and induce significant changes of the expression of membrane heat shock proteins(HSP70 or/and HSP90) on L615 leukemia and HCa-F hepatoma cells and the EC-TCVs (E+MMC+G treated in combination) showed the highest level of membrane HSPs expression (P＜0.05 or P＜0.01 );(4) The HSP70-peptide complex isolated from HCa-F EC-TCV through ADP-agarose affinity chromatographic system could induce active immunoprotection against lethal dose challenge of HCa-F hepatic cancer cell but could not protect against the cross challenge of lethal dose of L615 leukemia. The results indicated that the immunoprotective effect of EC-TCV was in some extent tumor-specific, MHC-nonrestricted, and HSPs might play an important role in its molecular mechanisms.

Objective To explore the relationship and influencing factors between pre‐diabetes mellitus (pre‐DM) and hypertension, providing evidence for formulating strategies for cardiovascular disease prevention and control. Methods We conducted this study from June 2013 to September 2014. Using stratified multistage random sampling, participants were administered a questionnaire survey, their height, weight, waist circumference, hip circumference, other physical attributes, blood pressure and blood lipids were measured. They also underwent the 75‐g glucose tolerance test and other laboratory examinations. A logistic regression model was used to analyze the relationship between pre‐DM and hypertension and its influencing factors. Results A total of 4 002 participants completed the survey. Participants'mean age was 50.3 ± 11.8 years. Of the total participants, 1 962 (49.0%) were males, while 2 039 (51.0%) were females; 1 participant had missing gender data. Further, 2 188 participants had normal glucose metabolism, 1 066 had pre‐DM, and 748 had diabetes. The prevalence of hypertension in participants with normal glucose metabolism, impaired fasting glucose, impaired glucose tolerance, both impaired fasting glucose and impaired glucose tolerance, and DM was 28.3%, 46.5%, 46.3%, 62.0%, and 61.2%, respectively. The prevalence of hypertension varied among people with different glucose metabolism (χ2=306.672, P<0.001). The prevalence of hypertension in the pre‐DM population increased with the aggravation of abnormal glucose metabolism compared to the normal glucose metabolism population, with a linear trend (χ2=299.009, P<0.001). Among those with abnormal glucose metabolism, there were differences in age, cholesterol, triglycerides, low‐density lipoproteins, body mass index, and waist circumference compared to those without hypertension (P<0.05). The risk of hypertension in the pre‐diabetic population was 1.5 times higher than that in the normal glucose metabolism population (OR=2.510, 95% CI: 2.156-2.922, P<0.001). There was no difference in the correlation intensity between pre‐DM and hypertension when gender was taken into account. Age and lipid abnormalities slightly decreased the correlation intensity between abnormal glucose metabolism and hypertension. Considering body mass index and centripetal obesity, the correlation intensity between abnormal glucose metabolism and hypertension could be reduced by controlling these factors. Conclusion The prevalence of hypertension is high in people with pre‐DM. There is a correlation between pre‐DM and hypertension, even when considering factors such as age, dyslipidemia, body mass index, and centripetal obesity. Therefore, it is necessary to strengthen the management of blood pressure in the pre‐diabetic population; improve early intervention for risk factors such as dyslipidemia, body mass index, and centripetal obesity; and reduce the occurrence of hypertension.

Objective To investigate the occupational health status of radiation workers in Dezhou, China, explore the effects of low-dose ionizing radiation on the health of radiation workers, and provide a basis for improving the health of radiation workers. Methods A total of 1101 radiation workers in Dezhou who underwent occupational health examination in 2021 were selected. The effects of physical examination type, type of work, sex, length of service, and age on the health status of radiation workers were compared and analyzed. Results The abnormal rates of abdominal color Doppler ultrasound and eye lens were significantly higher in pre-post radiation workers than in radiation works (P < 0.05). The abnormal rates of eye lens increased with the length of service in radiation workers (P < 0.05). The abnormal rate of abdominal color Doppler ultrasound in male workers was higher than that in female workers, while the abnormal rates of blood routine and thyroid function were higher in female workers than in male workers (P < 0.05). Conclusion The abdominal rates of color Doppler ultrasound and eye lens are relatively high among radiation workers in Dezhou. It is necessary to improve the protection awareness and strengthen the level of radiation protection, so as to ensure the occupational health of radiation workers.
