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 study the diagnosis and treatment of adrenocorticotrophic hormone (ACTH) independent Cushing syndrome. Methods A retrospective review was done on 89 patients with ACTH independent Cushing syndrome, including 85 cases of adrenal tumors with hypercorticism, 2 cases of adrenocortical adenocarcinoma and 2 cases with ACTH independent macronodular adrenal hyperplasia. Results Favorable results were observed from the surgery for 85 cases of adrenal tumors combined with hypercorticism.Two cases with ACTH independent macronodular adrenal hyperplasia were cured by bilateral adrenolectomy. Adrenal cortical adenocarcinoma was unresectable for both the patients who survived 7 and 9 months respectively. Plasma ACTH,dexamethasone suppression test,B ultrasonography and CT scan were useful for the diagnosis and differentiated diagnosis of ACTH independent Cushing syndrome. Conclusions Prognosis of adrenal tumors with hypercorticism and ACTH independent macronodular adrenal hyperplasia is favorable after surgery,whereas the prognosis of adrenal cortical adenocarcinoma is poor.

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 investigate the effects of transcranial magnetic stimulation(TMS)on the recovery of neurological function and the expression of neurofilament protein(NFP)-200 in rats with cerebral infarction.Methods The string-fastening method was used to establish focal ischemia-reperfusion models in 60 Sprague-Dawley rats and the rats were divided into the TMS group and the sham TMS group(composed of 30 rats each).Then each group were divided into the treated 1 d,3 d,7 d,14 d and 21 d subgroups(composed of 6 rats each).TMS group rats were administered with 2 sessions of TMS(200 pulses total)daily,keeping on corresponding days in different groups.The recovery of neurological function and the optical density of NFP-200 by immunohistochemistry in the infarct peripheral zone in two groups were detected after therapy.Results At the 14 d and 21 d after treatment,neurological deficit scores of TMS group(2.67?0.82,1.50?0.55) were significantly lower than those of the sham TMS group(3.67?0.52,3.17?0.75)(P
