0.05). As compared with Qingkailing group, the body temperature at the 5th day of treatment and WBC at the 3rd day of treatment were significantly decreased (P

Objective To investigate the effects of propofol on lipopolysaccharide (LPS)-induced brain injury in rats.Methods Fifty-four pathogen-free SD rats of both sexes, aged 6 weeks, weighing 200-250 g, were randomly divided into 3 groups: control group (group C, n = 6) ; LPS group (group L, n = 24) ; propofol group (group P, n = 24) . Brain injury was produced by injection of LPS 1 mg/kg via the left internal carotid artery in L and P groups. Propofol 100 mg/kg was injected intraperitonealry immediately after the LPS administration in group P, while the equal volume of normal saline was given instead of propofol in group L. The equal volume of normal saline was given instead of LPS and propofol in group C. Six rats in each group were sacrificed and the brain tissues were immediately removed at 24 h after intraperitoneal administration in group C, and at 6, 24, 48 and 72 h after intraperitoneal administration in L and P groups for determination of brain water content, high-mobility group box 1 ( HMGB1) expression and NF-κB activity, and microscopic examination. Results The brain water content and NF-kB activity were significantly increased, and HMGB1 expression was up-regulated in group L as compared to group C (P ＜ 0.05) . The brain water content, expression of HMGB1 and NF-kB activity were significantly lower in group P than in group L ( P ＜ 0.05) . The microscopic examination showed that brain injury was attenuated in group P compared with group L. The brain water content was positively correlated with the HMGB1 expression and NF- κB activity (r = 0.692 and 0.769 respectively, P ＜ 0.05). Conclusion Propofol can reduce the LPS- induced brain injury by reducing inflammatory response of the brain tissues.

Objective To study the expression and significance of CEA in occult micrometastasis ofcolorectal carcinoma. Methods 287 cases without metastatic lymph nodes were observed in 54 cases ofcolorectal carcinoma by immunohistochemical (LSAB) method. Results 15 cases of lymph nodes werefound with occult micrometastasis in 8 patients. All micrometastasis was positive in detection of CEA.Conclusion Detection of CEA was conducive to detect micrometastasis of lymphnode. It is significant forDukes staging,prognostic determination and treatment.

Aim To observe the effects of Xiatianwu tota l alkaloids ( XA ) on learning and memory impairment and the central cholinergic f unction in rats with quinolinic acid microinjected into bilateral hippocampus. Methods Alzheimers disease (AD) rat models were made by damagin g bilateral hippocampus with quinolinic acid (150 nmol in 2 ?l for each hippoca mpus). XA 0.25, 0.5, 1 mg?kg -1 was administrated ig from 1 week before model established to 3 weeks after model established. Y-maze was used to measur e the learning and memory ability. The activity of the acetylcholinesterase ( AC hE ) in hippocampus and the contents of acetylcholine ( ACh ) was determined by spectrophotometry. Results Microinjection of quinolinic acid in to the rats hippocampus induced learning and memory dysfunction (P

Objective To explore the changes of serum leptin level in patients with diabetic microangiopathy.Methods A total of 90 subjects were assigned to three groups which included 30 healthy controls,30 diabetic patients without microangiopathy and 30 patients with diabetic microangiopathy.The studing groups were matched for sex and BMI.The level of serum leptin ,ⅣC,insulin and glucose of these patients were measured,and the correlation between serum leptin level and other indexes was analyzed.Results The level of serum leptin in controls,diabetic patients without microangiopathy and patients with diabetic microangiopathy were (7.20?2.11) ?g/L, (7.95?3.78)?g/L and (10.26?4.37)?g/L respectively .The patients with diabetic microangiopathy had higher serum leptin levels than in the diabetic patients without microangiopathy( t =2.18, P

Objective To investigate the effect of acupuncture decompression operation on the quality of life of patients with mild to moderate essential hypertension. Methods 74 cases of mild to moderate essential hypertension were divided into experimental group and control group by random number table, 4 cases were lost. Finally, a total of 70 patients were included in the data analysis. In the control group, 35 cases were given routine drug taking and health guidance, the experimental group of 35 patients increase the treatment of acupuncture decompression operation points on this basis. The two groups of patients were measured with blood pressure before and after intervention, and World Health Organization Quality of Life (WHOQOL-BREF) was used to evaluate the quality of life, and the data were analyzed. Results The scores of physiological and psychological fields in the experimental group were (15.23 ± 2.66) points and (16.68 ± 2.23) points while the control group were (13.98 ± 2.18) points, (15.25 ± 2.52) points, the difference was statistically significant (t=2.305, 2.522, P<0.05). The experimental group of social relations, environmental score were respectively (1.37 ± 2.24) points, (14.16 ± 1.24) points, while the control group were (13.29 ± 2.30) points, (13.56 ± 1.36) points, 2 groups were not statistically significant (t=0.770, 3.063, P > 0.05). The experimental group systolic blood pressure, diastolic blood pressure were (121.43 ± 6.43) mmHg (1 mmHg=0.133 kPa), (71.74 ± 3.88) mmHg, compared with the control group were (128.34±5.72) mmHg, (76.06±4.43) mmHg. The difference was statistically significant (t=-4.753,-4.210, P<0.05). Conclusions acupuncture decompression operation can improve blood pressure in young and middle-aged patients with hypertension, improve the quality of life.
