Objective To explore the protective effect of 17β-estradiol on traumatic brain injury in rats.Methods A total of 45 adult male SD rats were divided into 3 groups using the random digit table, 15 rats in each group:the control group only exposed but not injured the brain, the injury group received traumatic brain injury ( TBI) by Feeney’ s method, and the treatment group received the same handling with injury group, and pretreatment with 17β-estradiol peritoneal injection, 1 mg/kg per day for one week.The other two groups were given the same volume of castor oil.At 6 h, 24 h and 48 h after injury, the brain tissue water content, malondialdehyde ( MDA) content and superoxide dismutase ( SOD) activity were measured.Results At 6 h, 24 h and 48 h after injury, the levels of brain tissue water content in the injury group and treatment group were significantly higher than those in the control group ( P<0.05 ) .At 6 h after injury, the brain tissue water contents in the injury group and treatment group were ( 99.83 ±0.40 )% and ( 99.53 ±0.41 )%,respectively, with a non-significant difference between the two groups (P>0.05).At 24 h and 48 h after injury, the brain tissue water contents in the injury group was ( 105.17 ±0.43 )% and ( 107.54 ±0.39 )%, in the treatment group was (103.26 ±0.42)%and (105.89 ±0.43)%, respectively, showing a significant difference between the two groups ( P<0.05).At 6 h after injury, the levels of MDA in the injury group and treatment group increased and maintained at a higher level, and the levels of SOD decreased.Compared with the control group, there had a significant difference ( P<0.05 ) . The levels of MDA and SOD in the injury group and treatment group at 6 h after injury had a non-significant difference ( P>0.05).But at 24 h and 48 h after injury, the levels of MDA in the treatment group were significantly lower than those in the injury group [(130.39 ±7.02) μmol/g vs.(149.41 ±8.25) μmol/g, (125.41 ±6.59) μmol/g vs.(157.72 ± 8.93) μmol/L] , and the levels of SOD in the treatment group were significantly higher than thoset in the injury group [(88.46 ±7.17) U/g vs.(80.10 ±4.87) U/mg, (97.31 ±7.89) U/g vs.(84.29 ±6.13) U/g], with a significant difference ( P<0.05 ) between the two groups.Conclusions 17β-estradiol has a protective effect on traumatic brain injury.

Objective To evaluate the clinical value of eversion carotid endarterectomy in patients with carotid atherosclerosis stenosis. Method Summarized the clinical data of 20 patients who accepted eversiou carotid endarterectomy from March 2009 to August 2009, compared the outcomes with preoperative and postoperative image learnt materials and clinical symptoms. Results All cases finished successfully. All clinical symptoms were improved after operation. The stenosis were all improved completely on the image after operation. Conclusions Eversion carotid endarterectomy is safe, effective, and shortening operative time and hospitalization time. It has low restenosis rate, thicken endometrium and plaque can be stripped completely.

ObjectiveTo evaluate the therapeutic effect ofZishen decoction combined with standard treatment of western medicine for for stage IV diabetic nephropathy with Qi and Yin deficiency.MethodsA total of 112 patients with stage IV diabetic nephropathy and Qi and Yin deficiency were randomized to thestandard treatment and the combined treatment groups, 56 in each. The standard treatment group received conventional treatment, including blood glucose controlling, antihypertensive, blood lipid regulating and diet controlling. The combined treatment group receivedZishen decoction on the basis of conventional treatment. All the patients were treated for 3 months. The blood urea nitrogen (BUN), serum creatinine (SCr), total cholesterol (TG), triacylglycerol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and glycated hemoglobin (HbA1c) were measured by an automatic chemistry analyzer. The urinary albumin excretion rate (UAER) was measured by the enzyme-linked immunosorbent assay.ResultsCompared with the standard treatment group, the SCr (53.51 ± 18.12μmol/Lvs. 62.66 ± 21.14μmol/L;t=2.459,P<0.05), UAER(100.73±84.24μg/minvs. 156.24 ± 96.38μg/min;t=3.245,P<0.05), TG(1.73±0.22 mmol/Lvs. 2.06 ± 0.21 mmol/L;t=8.112,P<0.01), TC(4.56 ± 0.62 mmol/Lvs. 5.10 ±0.31 mmol/L;t=5.830, P<0.01), LDL-C (2.42 ± 1.05 mmol/Lvs. 3.31 ± 0.81 mmol/L;t=5.022,P<0.01) in the combined treatment group decreased significantly, and the HDL-C (1.67 ± 0.33 mmol/Lvs. 1.36 ± 0.41 mmol/L;t=4.460,P<0.01) increased significantly. ConclusionZishen decoction on the basis of conventional treatment can improve the SCr and UAER, and regulate the blood lipid in the patients with stage IV diabetic nephropathy and Qi-Yin deficiency.

Objective To evaluate the effect of the self-made Zishen decoction combined with conventional western medicine therapy and health education on the patients with early diabetic nephropathy. Methods The 112 patients with DN were randomly assigned to 2 groups (each group 56 patients) at a ratio of 1:1. The control group was treated with control of glucose, blood pressure, lipid, and diet therapy, and the treatment group was with self-made prescription of invigorating the kidney and health education based on the control group treatment. All patients were treated for 6 months. The SF-36 scale was used to assess the quality of life, and the clinical effect was determined based on the blood biochemical indexes. Results Total clinical effect of the treatment group was 85.7%(48/56), and the control group was 67.9%(38/56) (χ2=4.057, P=0.044). Compared with the control group after treatment for 6 months, the physical condition (72.17 ± 13.41 vs. 64.59 ± 11.83, t=3.172), social function (64.58 ± 14.54 vs. 58.94 ± 14.62, t=2.047), physical role function (55.82 ± 10.11 vs. 47.46 ± 10.18, t=4.360), emotional role function (60.43 ± 10.20 vs. 56.04 ± 11.44, t=2.143), energy (69.86 ± 11.43 vs. 62.47 ± 11.12, t=3.468), general health status (68.57 ± 11.25 vs. 62.45 ± 11.78, t=2.812) of the treatment group were significantly improved (P<0.01 or P<0.05). Conclusion The self-made Zishen decoction and health education combined with conventional western medicine can improve the clinical effect and quality of life of patients with DN.
