In order to investigate the antiviral effect of chinonin against Herpes simplex virus (HSV), the encephalitis model in mice and skin infection model in guinea pigs were established by HSV- I and HSV-II infection respectively. Acyclovir was used as the positive reference drug to evaluate the antiviral capacity of chinonin. Chinonin showed an obvious therapeutic effect on encephalitis in mice at doses of 25 and 50 mg/kg. At both dosages, chinonin demonstrated stronger protection than acyclovir (1 and 5 mg/kg) to the infected mice from death. It was also found that chinonin could treat the skin infection in guinea pigs effectively. The therapeutic effect of chinonin was similar to that of acyclovir (5 mg/kg) at 25 mg/kg but obviously better than that at 50 and 75 mg/ kg. In conclusion, chinonin is a potential candidate for the treatment against HSV.

Objective To analyze the effects of health management of metabolic syndrome on the control of related risk factors. Methods A total of 430 patients diagnosed with metabolic syndrome in 2008completed questionnaire and before randomly assigned to the health management group ( n = 207 ) and the control group (n=223). One year later, all the participants were investigated for the risk factors of food intake, cigarette smoking, alcohol consumption, staying-up and emotion, and the changes of body mass index ( BMI), blood pressure ( BP), triglyceride (TG), high-density lipoprotein cholesterol (HDL) and fasting blood glucose (FBG). Student's t test and x2 test were used for data analysis. Results For the health management group, the incidence of high-salt, high-fat and high-sugar intake, overtake of food, lack of physical exercises,staying-up and alcohol drinking was significantly decreased at 1 year (P < 0. 05 ), when compared with baseline and the control group ( both P < 0. 05 ). For the health management group, BMI,systolic blood pressure (SBP),TG and FBG was improved at 1 year (P<0. 05). In comparison with the control group, BMI, SBP, diastolic blood pressure (DBP),TG and FBG of the management group were significantly improved (P < 0. 05 ). Conclusions Patients with metabolic syndrome may have better treatment compliance after receiving systematized and individualized health management.

Objective: To determine quercetin and kaempferol in stamen neulumbinis by HPLC. Methods : Shim-pack CLC-ODS column was used. Mobile phase consisted of methanol-0.025% phosphate. UV detector wavelength was set at 370nm. Results : The chromatographic peaks of quercetin and kaempferol and other components were completely separated. The average recovery was 96.8% and RSD was 1.97%. Conclusion : The experiment provided new markers and a reliable method for the quality control of Stamen Neulumbinis.

Objective To observe the characteristics of electro-neurophysiology in diabetic patients with early peripheral neuropathy. Method The nerve conduction velocity ( NCV ) and quantitative sensory test (QST) were examined in 175 diabetic patients without clinical peripheral neuropathy and in 50 normal subjects, and their results were compared. Results In 175 diabetic patients, the abnormal ratio of NCV was 7% (13/175).While using QST,the abnormal ratio was 45% (79/175). There was significant difference between two methods (P< 0.01). Compared diabetic patients with normal subjects,there was no significant difference between motor conduction velocity and sensory conduction velocity (P > 0.05 ).While using QST, the threshold values of cold sensation, warm sensation, and thermalgesia showed significant difference between diabetic patients and normal subjects (P< 0.01). Conclusion QST is more sensitive than NCV in diagnosing diabetic peripheral neuropathy, which suggests that small nerve fibers are more likely to be damaged than large fibers in early stage.

Objective To investigate the effect of dexmedetomidine on postoperative renal function of patients with rheumatic heart disease following valvular heart surgery. Methods Fifty patients following valvular heart surgery were randomized into experimental group and control group,with 25 cases in each group. The patients in experimental group receiveddexmedetomidine 0.5 μg/kg infusion 15min before induction, and then 0.5 μg/(kg·h) infused to the end of surgery, while those in control group received the same amount of saline in the same way. Blood from central venous was collected before surgery, at the end of surgery, 24 h and 48 h after surgery in order to detect Src, BUN and Cys C and the length of ICU duration was also recorded. Results Src and Cys C of the patients in both groups obviously elevated 24h after surgery when compared with pre-operation , while BUN elevated at both 24 h and 48 h after surgery(P < 0.05). Compared with those in control group, Src, BUN and Cys C were lower in experimental group ( P < 0 . 05 ) , and the length of ICU duration was shorter (P < 0.05). Conclusion Dexmedetomidine could improve the postoperative renal function after valvular heart surgery and lead to a better prognosis.

The paeonol proniosomes ointment and ordinary ointment were administered to rats. Physiological saline served as perfused solution. The perfusion rate was 5 mL x L(-1) and the microdialysis samples were collected every 20 min intervals. The paeonol concentration in perfused solution was determined by HPLC. Investigation of the pharmacokinetics of paeonol proniosomes ointment and ordinary ointment by the skin-blood synchronous microdialysis coupled with HPLC is reported in this study. The results show that the recovery was (54.80 +/- 1.50)% in vitro and (54.58 +/- 4.61)% in vivo. The results showed that paeonol proniosomes ointment significantly raised the drug concentrations in skin more than the paeonol ordinary ointment. The paeono proniosomes ointment has less drugs into the blood as the ordinary ointments in blood, but its blood drug concentrations were steadier. The paeonol proniosomes ointment may be developed into a new preparation.

OBJECTIVETo investigate the contents changes of potential biomarkers of patients infected with influenza A (H1N1) virus of different Chinese medicine (CM) syndrome types.
METHODSEighty-two patients with influenza A (H1N1) virus were differentiated as three syndrome types, i. e., wind-heat invading weifen syndrome (51 cases), heat-toxicity attacking Fei syndrome (22 cases), and superficies tightened by wind cold syndrome (9 cases) according to Chinese medicine syndrome typing. According to patients' willingness and clinical conditions, they were treated by three therapeutic schedules, i. e., herbal therapy, symptomatic treatment, and antiviral therapy. The changes of potential biomarkers contents were detected in the serum of patients of various syndrome types before and after treatment. Results There was no statistical difference in the potential biomarkers contents correlated to symptoms of fever, inflammation and cough, such as PGG2, 20-COOH-LTB4, homocystein, and so on in the serum of patients of various syndrome types before treatment (P > 0.05). There was statistical difference in the potential biomarkers such as 20-OH-LTE4, LTA4, and linolenic acid, etc. between superficies tightened by wind cold syndrome and wind-heat invading weifen syndrome (P < 0.05, P < 0.01). There was statistical difference in the potential biomarkers such as PGF1alpha, prostanoic acid, and etc. between superficies tightened by wind cold syndrome and heat-toxicity attacking Fei syndrome (P < 0.05, P < 0.01). Statistical difference existed in other indices other than dUTP; 5,10-methylene-THF and PGF1alpha in wind-heat invading weifen syndrome and superficies tightened by wind cold syndrome; prostanoic acid, homocysteine, and glucose in superficies tightened by wind cold syndrome when compared with before treatment in the same group (P < 0.05, P < 0.01). The changing tendency of potential biomarkers among different syndrome types was identical. Of them, the change of 6-keto-PGF1alpha content was the most obviously of all indices.
CONCLUSIONThere was difference in the contents of potential biomarkers of patients infected with influenza A (H1N1) virus of different syndrome types, and our study provided experimental data support for the objectiveness of CM syndrome differentiation from the perspective of metabolic substances.
