AIM: To develop a method of determining notoginsenoside R_1,ginsenoside Rg_1 and Rb_1 contents in Xinnaozhi Capsule(Radix et Rhizoma Notogineseng,Hirudo,Eupolyphaga seu steleophage). METHODS: HPLC was used to determine notoginsenoside R_1,ginsenoside Rg_1 and Rb_1 in Xinnaozhi Capsule.The separation was performed by Zorbax C_(18) colunm with acetonitrile and water using a gradient program at UV 203nm at room temperature.The elution program was 0-3 min,20%-25% acetonitrile,3-15 min,25%-45% acetonitrile. RESULTS: 3 saponins were separated well.Average recoveries were 102.93% for notoginsenoside R_1(RSD=(1.26%));105.68% for ginsenoside Rg_1(RSD=1.52%);104.34% for ginsenoside Rb_1(RSD=0.70%),respectively. CONCLUSION: The method is simple and rapid and with satisfactory results.It is suitable for quality control of Xinnaozhi Capsules.

Objective To test the hypothesis that nebulised budesonide (NB) might be an alternative to systemic corticosteroids in treatment of patients with exacerbated chronic obstructive pulmonary disease (ECOPD).Methods Patients hospitalised with ECOPD (n = 78) were randomnized into three groups.Group 1 received only standard bronchodilator treatment (SBDT),group 2 received systemic corticosteroids (SC 40 mg methylprednisolone) plus SBDT,and group 3 received nebulised budesonide ( NB 1000 mg budesonide q.i.d.) plus SBDT.Complete blood counts,detailed biochemical analysis,spirometric measurements and arterial blood gas analysis were carried out at admission.In addition,the following were recorded:adverse effects,discharging percentage of patients at 10 day and 15 day after hospitalization,exacerbation and re-hospitalization ratio within 1month after discharge.Results The improvement of SO2,PO2,FEV1 and discharge rates was ( 5.3± 0.9 ) %、(5.9 ±0.4)%、(8.7 ±0.5)% ,(8.1 ±0.8)%,(4.9 ±0.4)% and (7.2 ±0.5)% ,which were higher than that in SBDT group.These indexes were not different between 2 group and 3 group.The fraction of patients discharged on the 10th day and 15th were not different.The deteriorate rate was higher in 1 group than in 2 group and 3 group(P ＜0.05 ).Re-admission ratio in one month is higher in 1 group( 12% ) than in 2 group( 5% ) and 3 group(9% ) ( P ＜0.05 ).Absolute blood glucose level was found to be significantly higher in group 2 in 10th day (7.4 ± 1.6)mmol/L,which is greater than that in 1 group ( 5.1 ± 0.8 ) mmol/L and 3 group ( 5.6 ± 1.2 ) mmol/L ( P ＜ 0.05 ).Dysphoria and deliration appear in one patient in group 2.Conclusions Nebulised budesonide,an effective and safe alternative to systemic corticosteroids in treatment of exacerbated COPD,may substitute systemic corticosteroids in clinical practice.

OBJECTIVE: To study the antidepressant effects of total flavone of A( TFA) on post stroke depression ( PSD) in rats. METHODS: Middle cerebral artery occlusion ( MCAO) followed by isolation feed and irritable stimuli was used to induce PSD. Behaviours of rats were detected by open- field test . The effects of TFA on the indexes of hemorheology and brain homogenate lipid peroxidation were also tested. RESULTS: TFA could increase the crossing and rearing scores in open- field test, inhibit the elevation of whole blood viscosity as well as plasma viscosity at high- middle- low shear rates, increase the erythrocyte deformation, enhance the activities of Superoxide Dismutase ( SOD) and Glutathione Peroxidase ( GSH- Px) , and reduce Malondialdehyde ( MDA) content in brain homogenate in PSD in rats. CONCLUSIONS: TFA produces an antidepressant- like effect in PSD rats. This mechanism may be in association with attenuating hemorheological parameters and decreasing lipid peroxidative damage.

Objective To evaluate the efficacy and safety of small-middle endoscopic sphincterotomy combined with endoscopic papillary balloon dilation for patients with extrahepatic bile duct stone. Methods The patients with special duodenal papilla included 38 cases, and those with normal duodenal papilla 143 cases. 38 patients had received SEST + EPBD, 143 had received MEST + EPBD. Results 181 patients had received SMEST + EPBD in our hospital and the related data were retrospectively analyzed. All 181 patients were successfully removed, the success rate was 100.00 %. There was no perforation occurred postoperatively, but mild acute pancreatitis occurred in 8 patients (4.42 %, 8/181) and bleeding occurred in 9 patients. The three major early complications rate were 9.93 %(17/181), which was cured by the conservative management. Conclusion SMEST plus EPBD is a safe and effective treatment for extrahepatic bile duct stone, with retaining the feature of sphincter of duodenal papilla, especially for patients with special duodenal papilla.

Objective To investigate the inhibitory effect of IFN-γ on acute allergic airway inflammation induced by IL-33 in mice.Methods Twenty-four female C57BL/6 mice (6-8 weeks) were randomly divided into four groups: IL-33 model group, IFN-γ treatment group, IL-33+IFN-γ treatment group and PBS control group.A mouse model of acute allergic airway inflammation was induced by IL-33.Samples of bronchial alveolar lavage fluid (BALF) and lung tissues were collected.Group 2 innate lymphoid cells (ILC2s) and eosinophils were analyzed by flow cytometry.Levels of IL-5 and IL-13 in the supernatants of lung homogenate and BALF were measured by ELISA.Expression of IL-5, IL-13 and ST2 at mRNA level was detected by real-time PCR.Pathological changes in lung tissues were observed following hematoxylin and eosin (HE) and periodic acid-Schiff (PAS) staining.Results Compared with the PBS control group, no infiltration with inflammatory cells, goblet cell hyperplasia or mucus secretion was observed in the IFN-γ group;the numbers of ILC2s and eosinophils were not affected by IFN-γ;the levels of IL-5 and IL-13 in the supernatants of BALF and lung homogenate, and the expression of IL-5, IL-13 and ST2 at mRNA level in lung tissues were not significantly changed by IFN-γ (P>0.05).Compared with the PBS control group, massive infiltration with inflammatory cells, excessive mucus secretion, increased numbers of ILC2s and eosinophils, up-regulated levels of IL-5 and IL-13 in the supernatants of BALF and lung homogenate, and enhanced expression of IL-5, IL-13 and ST2 at mRNA level in lung tissues were detected in the IL-33 model group (P<0.05).Compared with the IL-33 model group, the combined treatment with IL-33 and IFN-γ significantly alleviated inflammatory cell infiltration, inhibited mucus secretion, reduced the numbers of ILC2s and eosinophils, down-regulated the levels of IL-5 and IL-13 in the supernatants of BALF and lung homogenate, and suppressed the expression of IL-5, IL-13 and ST2 at mRNA in lung tissues (P<0.05).Conclusion IFN-γ can inhibit the proliferation of eosinophils and ILC2s induced by IL-33, and reduce the secretion of IL-5 and IL-13, which indicates that IFN-γ has an inhibitory effect on acute allergic airway inflammation induced by IL-33 in mice.

Objective To study the clinical features and possible pathogenesis of acute ischemic stroke in renal cell cancer patients. Methods The clinical data from in-hospital patients with renal cell cancer who developed acute ischemic stroke were collected, including the patients with renal cell cancer who developed acute ischemic stroke during anti-cancer therapies and those patients with acute ischemic stroke who were firstly diagnosed to have renal cell cancer during anti-stroke therapies between January 2003 and December 2015. Results A total of 2516 patients with renal cell cancer were screened, and there were 36 patients (1.43%) with acute ischemic stroke. Out of the 36 patients, there were 29 men (80.56%) and 7 women (19.44%). Their age ranged from 45 to 68 years, with a average age of (65.11 ± 14.77) years. Eight patients (22.22%) had some conventional cardiovascular risk factors, while the other 28 patients (77.78%) had no such risk factors. Magnetic resonance imaging (MRI) scans at the acute stage of ischemic stroke were carried out for all these patients. Based on the diffusion weighted imaging (DWI) of MRI, 8 patients (22.22%) had single lesion and 28 patients (77.78%) had multiple lesions in different arterial territories in their brains. The pathological types of renal cell cancer were:suprarenal epithelioma (18 patients, 50.00%), papillary cell carcinoma (12 patients, 33.33%) and chromophobe renal cell carcinoma (6 patients, 16.67%). Metastases were found 10 patients (27.78%) out of the 36 patients. Blood biochemical examination showed that 28 patients had elevated plasma D-dimer level, 22 patients had elevated plasma cancer antigen (CA)125 level, and 17 patients had elevated plasma carcinoembryonic antigen (CEA) levels. Conclusions It is suggested that the renal cell cancer associated stroke is characterized by lacking of traditional risk factors and having multiple lesions in brain;and that the elevated plasma D-dimer, CA125 and CEA levels may lead to hypercoagulable state and lead to ischemic stroke eventually .
