This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1). This paper developed a selective, accurate and sensitive HPLC-FLD method for the simultaneous determination of four anthraquiones in rat plasma.

Objective To observe the effect of Changji'an Prescription(CP) on T lymphocytes count and 5-hydroxytryptamine(5-HT) secretion in rats with diarrhea predominant irritable bowel syndrome(IBS).Methods Forty-six neonatal SD rats were randomized into normal group,model group,low-,middle-and high-dose CP groups(0.94,1.88 and 3.76g?kg-1?d-1 respectively),and Bupi Yifei Pills group(6.76g?kg-1?d-1).Continuous internal rectal stimulation with acetate was used to induce the rat model of intestinal hypersensitive IBS.Flow cytometer was used for the quantitative analysis of peripheral levels of T lymphocytes subsets CD+3,CD+4 and CD+8,and immunohistochemical method was used to observe 5-HT-positive cells number and the immunostaining intensity in the bowels of rats.Results In the model group,the defecation volume and the intestinal sensitivity were increased,CD+4 level and CD+4/CD+8 decreased,CD+8 level increased,5-HT-positive cells number and the immunostaining intensity elevated(P

Aim To find out the relationship between muscarinic receptor and reactive oxygen species (ROS) and the probable differences between the four muscarinic receptor subtypes. Methods We transfected the plasmid encoding muscarinic receptor (including subtypes: M_1, M_2, M_3 and M_4) into PC12 cells. Then PC12 cells were exposed to hydrogen peroxide (H_2O_2), carbachol and other inhibitors such as atropine, LY294002 and PD98059. Results The results showed that activation of muscarinic receptor by carbachol protected PC12-M_1, PC12-M_2,PC12-M_3 and PC12-M_4 cells from apoptosis induced by H_2O_2. There was no statistical difference in the protective effect between these four muscarinic receptor subtypes. By using the inhibitors, we found that atropine and LY294002 blocked the protective effect of activation of muscarinic receptor on apoptosis induced by H_2O_2. Conclusion Activation of muscarinic receptor retarded the apoptosis induced by H_2O_2. There was no difference between the four muscarinic receptor subtypes. The protective effect was mainly mediated by the activation of muscarinic receptor and phosphatidylinositol-3 kinase (PI3K).

Objective To evaluate the effect of different types of tube feeding on swallowing function of stroke patients. Methods 60 patients with dysphagia post stroke were divided into observation group and control group with 30 cases in each group. The control group received indwelling nasogastric tube feeding, and the observation group received intermittent nasogastric tube feeding. They were assessed with Kubota Water Swallow Test (WST) and VGF on the 1st day and 30th day after admission. Results The scores of drinking test and VGF were better in the observation group than in the control group (P<0.05) on the 30th day. Conclusion Long-term nasogatric tube feeding is effective on dysphagia in stroke patients.

Background Granulocyte colony-stimulating factor(G-CSF)has been reported to have beneficial effect on cardiac dysfunction in post infarction and doxorubicin-induced cardiomyopathy.Objective To investigate the effects of G-CSF on cardiac remodeling in cardiac hypertrophy induced by angiotensin Ⅱ(Ang Ⅱ).Methods Thirty-six male wild type mice(WT)were allocated randomly to receive subcutaneously G-CSF(10 ?g/kg per day, n=9),or Ang Ⅱ(2.88 mg/kg per day,n=9),or Ang Ⅱ plus G-CSF(Ang Ⅱ 2.88 mg/kg+G-CSF 10 ?g/kg,n =9)for 4 weeks with untreated WT(n=9)as controls.Blood pressure and cardiac function were measured. Heart weight/body weight ratio,myocyte cross-sectional area and fibrosis area were determined.The mRNA ex- pression of osteopontin(OPN)in myocardium was detected by RT-PCR.The expressions of angiotensin converting enzyme(ACE),ACE2 and phosph-p70S6 kinase protein in myocardium were assessed by Western-Blot.Results Ang Ⅱ significantly elevated blood pressure(SBP,Ang Ⅱ:139.7?1.6 vs WT:108.7?2.3 mmHg,P0.05),but significantly attenuated the myocyte cross-sectional area(Ang Ⅱ+G-CSF:181.06?0.11 vs Ang Ⅱ:202.02?0.16 ?m~2,P

AIM To investigate the protection of plicamycin on apoptosis in cerebellar granule neurons (CGN) of rat. METHODS TUNEL, Hoechst 33258 staining, agarose gel electrophoresis and fluorescein diacetate staining were used to detect morphological and biochemical characteristics of apoptosis in primary rat CGN. RESULTS Being pre-incubated with plicamycin for 1 h and lasting for 24 h, rat CGN apoptosis induced by low potassium basal modified Eagle′s medium for 24 h was inhibited in a plicamycin concentration-dependent manner. This effective concentrations of plicamycin were from 50 to 200 nmol·L-1, and the maximum inhibitory rate of plicamycin on CGN apoptosis was near 80% at 200 nmol·L-1. CONCLUSIONPlicamycin inhibits rat CGN apoptosis induced by low potassium.

Objective To compare the clinical and radiological outcomes between hybrid and total pedicle screw instrumentation in adolescents undergone posterior spinal fusion (PSF) for thoracic scoliosis secondary to Chiari malformation..Methods A total of 75 patients undergone PSF were included and divided into two groups:the all pedicle screw group (Group A,n=44) and the hybrid group (Group B,n=31).Patients were evaluated before surgery,immediately after surgery,and at the 2-year follow-up in radiographic changes in curve magnitude,apical vertebral translation (AVT),apical vertebral rotation (AVR),trunk shift,thoracic kyphosis (TK),lumbar lordosis (LL),and sagittal vertical axis (SVA).These parameters were further analyzed with respect to preoperative TK in both groups.Results After surgery,the average correction of the thoracic curve was 60.2％ and 51.3％ in Group A and B,respectively (t=2.372,P=0.023).The average lumbar curve correction was 61.7％ in Group A,representing a significant increase compared to Group B (51.1％,t=2.431,P=0.020).At the final follow-up,loss of the thoracic curve correction was less in Group A (0.3％) than in Group B (1.7％),however,there was no statistical significance (t=-0.468,P＞0.05).AVT of the thoracic curve improved in Group A from 25.0 mm to 6.9 mm,while in Group B it changed from 24.1 mm to 7.4 mm.For patients with a preoperative TK greater than 40°,the proximal junctional angle was found to be significantly larger in Group A (10.0 degrees versus 4.5 degrees,t=-2.031,P=0.052) by the final follow-up,along with a significantly increased incidence of proximal junctional kyphosis (20％ versus 9％).Conclusion Total pedicle screw instrumentation provided a significantly better correction of the major and minor curves than hybrid constructs for the operative treatment of thoracic scoliosis secondary to Chiari malformation.However,for patients with thoracic hyperkyphosis,all-screw instrumentation had a higher risk of adjacent level proximal kyphosis.

A dispute about the decreasing-price problem of traditional Chinese medicine (TCM) has recently arisen. This article analyzes the statistical data of 1995-2011 in China, the results showed that the main responsibility of expensive health care has no direct relationship with the drug price. The price index of TCM rose significantly slower than the medicine prices, the production margins of TCM affected by the material prices has been diminishing since 1995, continuous price reduction will further depress profits of the TCM industry. Considering the pros and cons of raw materials vary greatly in price, decreasing medicine price behavior will force enterprises to use inferior materials in order to maintain corporate profits. The results have the guiding meaning to medicine price management.
