The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To evaluate the incidence,potential hazards and effective countermeasure for perforator stroke (PS) resulting from stent angioplasty of symptomatic intracranial artery stenosis.Methods Peri-operation PS complications of 258 patients receiving Gateway balloon-Wingspan stenting for severe symptomatic intracranial stenosis were analyzed.The incidence,clinical course,and prognosis of PS resulting from stenting were recorded.Special attention was given to the anatomical features,clinical manifestation and video materials of patients with PS.x2 test was used for statistics.Results Two hundred and fifty-five patients received stent angioplasty successfully and 7 patients had PS ( incidence rate 2.7％ ).The patients with basilar artery stenosis had a higher incidence of PS resulting from intracranial stenting (6.1％,4/66) than patients with middle cerebral artery stenosis (2.5％,3/118) (x2 =2.320,P =0.025 ).The potential hazards for PS included preoperative perforator stroke adjacent to the stenotic segment and prominent dissection during operation.Six patients presented symptoms after awake from general anaesthesia and one had symptoms 3 hours after stenting.One deteriorated gradually and the others reached the maximum deficit almost at once.At the follow-up of 3 months,3 patients were disabled and scored one,two,two by mRS respectively.Conclusion The incidence of PS resulting from intracranial stenting was low and the prognosis was not disastrous.Stenosis at basilar artery and preoperative perforator stroke adjacent to the stenotic segment were potential risk factors for PS complication.Proper maneuver of angioplasty may decrease the incidence of PS and improve the prognosis.

OBJECTIVETo explore the internal fixation selection and the operative method of Pilon fracture.

METHODSFrom Aug. 2004 to Aug. 2007,there were 40 patients with Pilon fractures involving 30 males and 10 females. Thirty cases were closed fracture and 10 were open fracture. Seven patients were treated by emergency operation, 3 patients were debrided and suture at first. Twenty-three patients were treated with open reduction and internal fixation (ORIF),the other seventeen patients were treated with LC-DCP,reconstruct plate for fixation or screw, Kirschner wire combine screw for fixation.

RESULTSAll patients were followed up for 6 to 32 months (means 19 months). The time of union of fracture was about 3 to 5 months. The outcome was evaluated according to Baired-Jackson criteria, the results were excellent in 27 cases,good in 7, fair in 5, poor in 1. Seven cases were found the operative incision and wound surface difficult to heal,among them 5 cases came from the emergency operation patients, 1 case was closed fracture patient. They were be healed by change of dressing or dermatoplasty or skin flap.

CONCLUSIONIt is the key factor of treatment for Pilon fractures to correct evaluate before operation and select correct operation time. It is also important to selected suitable internal fixation and good reduction.

OBJECTIVETo evaluate the efficacy and safety of using Jiangzhi Tongluo Soft Capsule (JTSC) combined with Atorvastatin Calcium Tablet (ACT) or ACT alone in treatment of combined hyperlipidemia.

METHODSA randomized, double blinded, parallel control, and multi-center clinical research design was adopted. Totally 138 combined hyperlipidemia patients were randomly assigned to the combined treatment group (A) and the atorvastatin treatment group (B) by random digit table, 69 in each group. All patients took ACT 20 mg per day. Patients in the A group took JTSC 100 mg each time, 3 times per day. Those in the B group took JTSC simulated agent, 100 mg each time, 3 times per day. The treatment period for all was 8 weeks. Serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were observed before treatment, at week 4 and 8 after treatment; and safety was assessed as well.

RESULTSAt week 4 and 8 after treatment serum TG decreased by 26.69% and 33.29% respectively in the A group (both P < 0.01), while it was decreased by 25.7% and 22.98% respectively in the B group (both P < 0.01). At week 8 decreased serum TG was obviously higher in the A group than in the B group (P < 0.05). Compared with before treatment, serum levels of LDL-C and TC levels decreased significantly in the two groups (all P < 0.01). There was no statistical difference in the drop-out value and the drop-out rate of serum LDL-C and TC levels (P > 0.05). At week 8 the serum HDL-C level showed an increasing tendency in the two groups. No obvious increase in peptase or creatase occurred in the two groups after treatment.

CONCLUSIONJTSC combined with ACT could lower the serum TG level of combined hyperlipidemia patients with safety.

Objective To evaluate the application of high-throughput shell vial assay in a clinical laboratory for detection of respiratory viruses from patients with ILI in Guangzhou between January and June, 2009. Methods Six hundred and fifty-two pharyngeal swab specimens were taken from ILI patents. Centrifugation-enhanced shell vials including 4 cell lines (MDCK, Hep-2, LLC-MK2 and MRC-5) were used for culture of respiratory viruses for 2-3 days. The cultures were identified by observation of cytopathic effect (CPE) , hemmaglution or hemmadsorption test as well as immunofluorescence staining. Results A total of 161 swab samples (24.69% ,161/652) were shown to have any one of the 5 common respiratory viruses including influenza A viruses ( 38. 51% , 62/161 ), influenza B virus ( 54. 65% , 88/161 ), parainfluenza viruses (4. 96% , 8/161 ) , adenovirus ( 1. 24% , 2/161 ), and respiratory syncytial virus (0. 62% ,1/161). The turnaround time was 2d for influenza viruses, 3d for adenovirus and parainfluenza viruses respectively. Conclusions (1) The shell vial method was effective, rapid and high throughout for the detection of respiratory viruses in clinical laboratories.(2)Influenza viruses were dominant in the swab samples from patients with ILI in Guangzhou between January and June with the highest appearance in the summer influenza B vires was the most common pathogen in patients with ILI in this study.

Objective To understand the current status and relative factors on knowledge, attitude, practice to contraception among college students in Beijing and to provide evidence for developing aimed contraceptive service and education in colleges. Methods Quantitative surveys were employed, questionnaire was conducted anonymously among 12 450 unmarried college students under informed consent. Results Among 12 129 students, acknowledgement of contraceptive knowledge among females was superior to males in college(P=0.000). Rates on the favor for unmarried sexual practice and 'sexual liberation' were 81.9% and 60.2% for males, comparing to 74.8% and 54.3% for females respectively. The prevalence rates for masturbation were 74.3% for males and 24.9% for females respectively. 18.4% of the male and 10.5% of the female students had ever experienced unmarried sexual intercourse. Among those students who had sexual experiences, 29.4% of the males had made their sex partners pregnant and 23.1% of the female students had experienced unexpected pregnancy. Statistical significance was found between males and females (P=0.000) in terms of attitudes and behaviors. 51.3% of the male and female students took contraceptive measures during the episode of first sexual intercourse. The excuses for not taking any measures would include: sexual intercourse happened incidentally, not interested in using condom, only one sexual experience would not cause pregnancy, etc. Conclusion The prevalence of unmarried sexual intercourse among college students had been rising. Among those who had experienced unmarried sexual intercourse, the rate of taking contraceptive measures was low and the incidence of unexpected pregnancy was high. It is urgent to strengthen the education and service programs on contraception among college students.

Objective To investigate the protection effect of Hedysarum polybotrys polysacchcaide ( HPS) on early diabetic nephropathy ( DN) in db/db mice.Methods Fifty db/db male mice ( five weeks old ) were randomly divided into five groups:HPS ( low-dose , mid-dose , hing-dose) groups, telmisartan group, model group.Ten db/m mice ( five weeks old ) were employed as normal group.At the beginning of 6 weeks, were respectively given 200,100, and 50 mg · kg -1 HPS; 5 mg· kg-1 telmisartan.The mice in normol group and model group were given 0.9%NaCl by gavege.The 24 hours urine protein were measured after administration 8 weeks and kill the mice with remove blood and serum was isolated from the eye .And the related indexes were evaluated.Results After interventing 8 weeks,compared with model group , serum creatinine ( Scr) 24 hours urine proteinall in HPS and telmisartan groups decreased ( P<0.05 ).The levels of blood glucose , blood urea nitrogen ( BUN ) , the expression of p 38 mitogen -activated protein kinase ( p38 MAPK ) and matrix metalloproteinases ( MMPs ) mRNA all decreased , but only the high , middle doses groups of HPS were statisti-cally difference ( P <0.05 ) .Conclusion Which indicates that HPS could delay the development of DN by inhibiting the P 38MAPK,MMPs protein and mRNA expression in the glomerular mesangial cell membrane.
