Objective To investigate the effect of hyperuricemia(HUA) on inflammation and endothelin-1 (ET-1) production and treatment of Benzbnomanone in hypertensive patients.Methods 90 initial hypertensive patients were enrolled from the inpatient division and clinic of our hospital,60 patients of them were identified HUA,and 30 patients were normal in uric acid as control.All these hypertensive patients with HUA were treated with basic anti-hypertensive drugs,of them 30 patients were additionally treated with Benzbromarone table 50mg for 8 weeks.The levels of inflammation indices and ET-1 were compared between these hypertensive patients with HUA and hypertensive patients with normal serum uric acid,also hypertensive patients with HUA treated with or without Benzbromarone for 8 weeks.Results Compared with the hypertensive patients with normal serum uric acid,levels of ET-1,interleukin-1 (IL-1) and high-sensitive C reactive protein (hsCRP) were higher in the hypertensive patients with HUA.Also,the levels of these indices were positively correlated with the level of serum uric acid [(86.6 ± 4.8) pg/ml vs (82.4 ±6.9)pg/ml; (47.6 ±6.2)mg/L vs (19.1 ±4.1) mg/L; (3.4 ±0.8)mg/L vs (2.9 ± 1.1)mg/L,r =0.81,0.74,0.83,all P ＜ 0.05].Benzbromarone could effectively decrease the levels of ET-1,IL-1and hsCRP in the hypertensive patients with HUA [(49.8 ± 5.0) pg/ml vs (87.5 ± 5.9) pg/ml ; (17.6 ±8.8) mg/L vs (48.2 ± 7.0) mg/L; (1.7 ± 0.7) mg/L vs (3.5 ± 0.9) mg/L,all P ＜ 0.05].Conclusions HUA could increase the levels of inflammation and ET-1,while Benzbromarone effectivelv decreased these changes.Decreasing the level of serum uric acid would retard the process of atherosclerosis in the hypertensive patients with HUA.

Objective To investigate the effect of electroacupuncture on the expression ofα-amino-3-hydroxyl-5-methyl-4-isoxazole propionate (AMPA) receptor associated protein glutamate receptor interacting protein (GRIP)1 and GRIP2 in hippocampal neurons of rats with Alzheimer's disease (AD) model induced by Aβ25-35. Methods 40 Male Sprague-Dawley rats were randomly divided into normal group, sham operation group, model group and electroacupuncture group with 10 rats in each group. The AD rat model was prepared by injecting Aβ25-35 in the hippocampus CA1 of rats, while the sham operation group was injected with equal amount of normal saline at the same loca-tion. On the second day after successful modeling, the electroacupuncture group received electroacupuncture at Baihui (DU20) and bilateral Shenshu (BL23) acupoints, once a day, 6 times a week for 2 weeks. The expression of GRIP1 and GRIP2 were detected with immunohisto-chemistry. Results There was no difference in the expression of GRIP2 and GRIP1 proteins in hippocampus between the normal group and sham operation group (t<1.7438, P>0.05), but was lower in the model group and the electroacupuncture group than in the sham operation group (t>9.5928, P<0.001), and was higher in the electroacupuncture group than in the model group (t>9.5326, P<0.05). Conclusion Elec-troacupuncture may increase the number of AMPA receptors on the postsynaptic membrane by increasing GRIP1 and GRIP2.

Objective To investigate early changes of angiopoietin-2(Ang-2)in multiple trauma patients and assess its clinical significance.Methods Forty-five multiple trauma patients aged 2060 years admitted to the hospital within one hour after injury were randomly divided into three groups according to injury severity score(ISS).Blood specimens were obtained immediately upon arrival in the emergency department and plasma samples were assayed for comparing changes of Ang-2,TNF-a and IL-6.Meanwhile,plasma level of Ang-2 was measured and analyzed under different oxygenation index,shock index and base deficit.Results Plasma level of Ang-2 was positively correlated with ISS(P ＜ 0.01)and was concordant with the plasma levels of TNF-a and IL-6(P＜0.01).Furthermore,plasma level of Ang-2 was elevated upon increase of shock index or decrease of oxygenation index(P ＜ 0.01).Plasma level of Ang-2 was elevated with the increase of base deficit(P ＜ 0.01).Conclusions High level of Ang-2 is a marker of endothelial activation and dysfunction early after trauma.Ang-2 is related tightly with the injury severity,inflammation factors,systemic oxygenation and tissue hypoperfusion and may have a tight relation with pathophysiological development and clinical outcome after trauma.

Objective Explore reflux esophagitis age,symptoms,and the relationship between the degree of esophageal damage.Methods Summing up 198 cases of young and middle-aged patients and 104 cases of elderly pa-tients with the symptom score and Endoscopic mucosal injurs classification.Results Under the old group gastroscopy serious esophagitis more than the young group,old age group was 49.97%,25.25%for the young group,but the clini-cal symptoms of heart burn not obvious.Conclusion Reflux esophagitis damaged esophagus increased with age in-crease,but clinical heartburn symptoms do not necessarily obvious,it should attach importance to the brink throat dis-comfort,and other symptoms.

Objective:To observe the effect of breathing andDaoyin exercises on the quality of life in patients with stable chronic obstructive pulmonary disease (COPD) due to deficiency of the lung and kidney (grade II-III).
Methods:A total of 60 eligible cases were randomly allocated into a treatment group (n=30) and a control group (n=30) by random number table. Cases in the control group received routine Western medical treatment, whereas cases in the treatment group conducted breathing andDaoyin exercises in addition to routine Western medical treatment. Patients in both groups were treated for a total of 3 months. Then the observation was made on changes in pulmonary ventilation function, major clinical symptoms, modified Medical Research Council scale (mMRC), distance in 6-minute walk test (6-MWT), COPD assessment test (CAT) and efficacy satisfaction questionnaire for COPD (ESQ-COPD) before and after treatment.
Results:After treatment, the total effective rate was 80.0% in the treatment group, versus 66.7% in the control group, showing a statistical difference (P<0.05). Patients in the treatment group obtained more significant improvement in coughing, sputum production, dyspnea and shortness of breath than those in the control group (P<0.05). Patients in the treatment group obtained more significant elevation in the forced expiratory volume in 1 second percentage of predicted value (FEV1%) and peak expiratory flow rate (PEF%) than those in the control group (P<0.05). Patients in the treatment group obtained lower mMRC score than those in the control group (P<0.05). Patients in the treatment group obtained longer 6-MWT distance than those in the control group (P<0.05). Patients in the treatment group obtained lower CAT score (P<0.01) and higher ESQ-COPD score (P<0.05) than those in the control group.
Conclusion:Breathing andDaoyin exercises combined with routine Western medical treatment are effective for stable COPD (grade II-III) due to deficiency of the lung and kidney and can improve the patients’ quality of life.

OBJECTIVE To explore the effect of E-cadherin on the proliferation ability of Hep-2 by method of RNA interference technology to silence the expression of E-cadherin. METHODS The specific siRNA sequences and non-silencing siRNA were designed and synthesized. Hep-2 cells were transfected and then the down expression of E-cadherin gene in vitro cultured Hep-2 cells were got. The silencing effect of E-cadherin gene was explored by Fluorescence Quantitative Polymerase Chain Reaction and the proliferation of the transfected Hep-2 cells were detected in vitro by MTT assay. RESULTS 1.When transfected with the ratio of recombinant plasmid and the quality of liposome volume at 1:1, the transfection efficiency at the siRNA-3 group was the highest and can be up to 65%. 2.The results of Fluorescence Quantitative Polymerase Chain Reaction: recombinant plasmid pRNAT-U6.1/Neo-siRNA1, pRNAT-U6.1/Neo-siRNA2 and pRNAT-U6.1/Neo-siRNA3 can down regulate the expression of E-cadherin mRAN. Set blank control group as a baseline (set to 1), the changes of expression of E-cadherin relative to β-actin in siRNA-1group was 0.00092, siRNA-2 group was 0.00143, siRNA-3 group was 0.00045 and the negative control group was 3.44898. The difference was statistically significant (P<0.05). 3. MTT: The growth rate of Hep-2 cells treated by specific siRNA was faster than that of the control group, and the difference was statistically significant (P<0.05). CONCLUSION Effectively inhibition the expression of E-cadherin's mRAN can enhance the proliferation of Hep-2 cells.

Objective To observe the effects of electroacupuncture ( EA) on learning and memory ability and the expression of N-ethylmaleimide-sensitive fusion factor ( NSF) in experimental Alzheimer′s disease ( AD) and to explore the mechanism involved. Methods Sixty healthy, male Sprague-Dawley rats were randomly divided into a normal group, a sham operation group, a model group and an EA group, each of 15.The model group and the EA group were injected with Aβ25-35 bilaterally in the CA1 area of the hippocampus, while the sham operation group was injected with the same amount of normal saline in the same regions. From the 1stday after the AD model had been es-tablished successfully, EA was applied to the Shen Shu ( BL23) and Bai Hui ( GV20) acupoints in the EA group once a day,6 days a week for 2 weeks. No EA was given to the other 3 groups. After the treatment, Morris water maze tests were conducted to determine assess the rats′ learning and memory ability, and immunohistochemical methods were used to test the expression level of NSF in the CA1 areas of the rats′hippocampus. Results The average es-cape latent period of the EA group was significantly shorter than that of the model group and their average platform crossing time was significantly longer. The average expression of NSF in the EA group measured as integrated optical intensity was significantly higher than that in the model group. Conclusion EA can effectively improve learning and memory ability in AD, at least in rats. The mechanism may involve increasing the expression of NSF in the CA1 area of the hippocampus.
