An HPLC-UV method was developed for the determination of total naringenin and total hesperetin in rat plasma after oral administration of Citrus aurantium Immaturus extracts and Zhizi Dahuang decoction. Plasma samples were pretreated with liquid-liquid extraction procedure and acid hydrolysis method was used for converting conjugated naringenin and hesperetin to their respective free forms. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 microm), using 0.1% phosphoric acid and methanol as mobile phase at a flow rate of 1.0 mL x min(-1) with gradient elution. DAS 2.0 software was applied to calculate the pharmacokinetic parameters while the SPSS 16.0 software was used for statistical analysis. Significant differences were observed, the C(max) AUC(0-t) of total naringenin in ZS group was 73.5% and 65.9% higher than those in ZZDHD group, respectively; the C(max), AUC(0-t) of total hesperetin in ZS group was 63.5% and 119.1% higher than those in ZZDHD group, respectively. There is a obvious decrease in C(max) and AUC(0-t) of total naringenin and total hesperetin after compatibility and their pharmacokinetic characteristics changed greatly due to the combination of other herbs. The established method was rapid, sensitive, selective and accurate, and it could be applied in the determination of total naringenin and total hesperetin in rat plasma.

This article summarized the application of Quality of Life in Parkinson's disease such as in therapy or nurse assessment, and discussed how it can be used to assess the effect of Traditional Chinese Medicine on Parkinson's disease, which suggest that a Sinicized Patient Reported Outcome (PRO) measure should be advanced.

Objective To explore protective effect of heparin on renal of children with Henoch-Schonlein purpura(HSP).Methods Two hundred and fifteen cases with HSP were divided into heparin-treated group(110 cases,male 64,female 46) and control group (105 cases,male 61,female 44).Serum IL-6 and IL-8 levels were examined by using radioimmunoassay respectively.These patients were followed up for more than 6 months.Results 1.The level of IL-6,IL-8 did not show significant difference between heparin-treated group and control group before treatment.The serum concentrations of IL-6,IL-8 in heparin-treated group were obviously lower than those in control group,after treatment,there was significantly different[IL-6(116.50?19.45)vs(123.88?22.55)ng /L,t=2.573 P=0.011;IL-8(0.161?0.043)vs(0.173?0.048)?g/L,t=2.024 P=0.044].2.During more than 6 months follow-up there were 26 cases suffering from purpura nephritis in heparin-treated group, the morbidity was 25%; the morbidity in control group was 39.8%,the morbidity in treatment group was significant lower than that in control group(?2=5.061 P=0.024).The time of renal injury was significantly delay in treatment group(35.0?13.2)d compared with that of control group (26.0?12.1)d(t=2.659 P=0.010).Conclusions The serum IL-6 and IL-8 concentrations in HSP obviously decrease after heparin treatment.Heparin therapy can decrease the morbidity of renal injury in children with HSP and delay the time of renal injury effectively.

Objective To analyze drug resistance of pathogenic bacteria from the blood culture and distribution in clinical departments,and to guide the rational clinical drug use.Methods We retrospectively analyzed 11 275 samples of blood cultures in The Central Hospital of Wuhan from 2012 to 2014.The blood specimens were cultured by VersaTREK(USA).The pathogenic bacteria were identified and their drug resistance was analyzed by BD-PHOENIX 100 automicrobiological identification systems(USA).Results Among the 11 275 blood cultures,636 bacterial strains were detected.The top four bacterial strains were Escherichia coli,Staphylococcus aureus,Klebsiella pneumonia and Enterococcus f aecium.A vancomycin-resistant Enterococcus faecium strain and a pandrug-resistant Klebsiella pneumoniae strain were detected.The top three clinical departments with distribution of pathogens were Gastroenterology Department,Nephrology Department and Intensive Care Unit (ICU).Pathogens isolated from ICU were evenly distributed.Conclusion Distributions of pathogenic bacteria in the blood culture are different in clinical departments.Identification of pathogenic bacteria and result of drug susceptibility can reduce use of broadspectrum antimicrobials and enhance antimicrobial de-escalation.

Objective To compare the graft function of 2 methods of kidney harvesting,the modified method of combined liver and kidney procurement and rapid en bloc kidney procurement. Methods The clinical data of 220 cadaveric renal transplantation recipients were collected(12 months follow-up),174 cases from en bloc kidney procurement and 46 from combined liver and kidney procurement.The average harvesting time,the incidence of renal vein injury,1 year kidney survival and incidence of acute rejection were compared between the two methods.Results In average harvesting time and incidence of renal vein injury,the en bloc kidney procurement were better than the method of combined liver and kidney procurement.However,the method of combined liver and kidney procurement was better than the en bloc kidney procurement in 1 year kidney survival,1 year incidence of acute rejection and average warm ischemia time.There was no difference in 1 year survival of patients and 24 h,1 week and 1 year graft function after transplantation. Conclusion Although the method of combined liver and kidney procurement is better than the en bloc kidney procurement in 1 year kidney survival and 1 year incidence of acute rejection,there is no difference between the 2 methods in 1 year survival of patients and graft function after transplantation.

As a new concept, the definition of translational medicine remains obscure. The translational medicine connects the bench to bedside, and its importance would be more remarkable. The development of gastrointestinal surgery reflects the idea of translational medicine. To carry out the translational study, the gastrointestinal surgeon must learn how to find subjects from clinical problems, how to collect complete information and tissues, how to collect complete information and tissues, how to collaborate with others from different fields and how to utilize all kinds of resources. By translational studies, gastrointestinal surgeons may further improve the survival of patients with gastrointestinal tumor.
