Objective To study the collision-induced dissociation fragmentation pathways of the jasminoidin and catalpol in ESI-Msn. Methods The samples were studied by using high performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-Msn) both in positive and negative. Results The collision-induced dissociation fragmentation pathways of both compounds were described. In the spectrum of two compounds, the loss of glucose residue and whole glucose were observed in positive mode, while only the loss of glucose residue could be observed in negative mode. Furthermore, we found that as the effect of the substituting groups, the fragment ions of jasminoidin were more in positive mode and those of catalpol were more in negative mode. Conclusion Conclusion The established method could be used for the sensitive and rapid identification of this kind of iridoid glycosides。

This report presented a case of 62-year-old woman who was admitted to our hospital for cirrosis, but she had a variety of clinical manifestations,such as abdominal distension,diarrhea,ascites, hepatosplenomegaly,anemia, palpitation, flushing, low blood pressure, arrhythmia and so on. Upper gastrointestinal endoscopy showed thicken mucosa at gastric fundus. Colonoscopy revealed nodular, pseudopolypoid. Ascitic fluid test suggested a transudate. Endoscopic abnormal mucosa biopsy showed chronic inflammation. Many mast cells were seen in bone marrow and liver biopsies,and liver tissue immunophenotype was CD117, and CD68. Thus the patient's diagnosis was systemic mastocytosis. It is rare that a patient only has the gastrointestinal tract symptoms complicated with ascites without skin lesion. The goal for treatment was to reduce hypersecretion of mast cells.

Objective To investigate the relationship between the nerve function and the sorbitol concentrations of erythrocyte and sciatic nerve, and to evaluate the effects and mechanism of a formulae of Chinese medicine, Shen Mai Huo Xue Yin (a decoction, it ingredients including ginseng, tuber of dwarf lilyturf and safflower) on diabetic peripheral neuropathy (DPN). Methods The rats were divided into 3 groups: normal rats, diabetic rats and diabetic rats treated with Shen Mai Huo Xue Yin. The diabetes of rats was induced by streptozotocin intraperitoneally. Motor nerve conduction velocity (MNCV) of sciatic, sensory nerve conduction velocity (SNCV) of caudal nerve and the H reflex were detected with evoked electromyogram; The sorbitol concentrations of erythrocyte and sciatic nerve was measured by spectrophotography. Results The sorbitol concentration of erythrocyte was positively correlated with that in the sciatic nerve, and the sorbitol concentration of erythocyte and sciatic nerve were negatively correlated with SNCV and positively with H reflex. The SNCV reduced significantly and the sorbitol concentration of both erythrocyte and sciatic nerve increased significantly in diabetic group as compared with those in normal group. The SNCV and sorbitol concentrations of sorbitol both erythrocyte and sciatic nerve in diabetic group were significantly improved after treated with Shen Mai Huo Xue Yin. Conclusion The sorbitol concentration in erythrocyte reflects the level of that in sciatic nerve and the lesion degrees of DPN. Shen Mai Huo Xue Yin alleviates the lesion of DPN in the early stage.

Objective To investigate the causes of death and the influencing factors in patients with peripheral arterial disease(PAD) during the perioperative period and reduce the perioperative mortality.Methods A retrospective analysis of the causes of death was performed for PAD during the perioperative period in our hospital from July 2005 to July 2010. Results Nine patients died preoperatively.The causes of death were multible organ failure in 5,heart failure in 2,sudden cardiac death in 1,and respiratory failure in 1.Six patients died postoperatively.The causes of death were acute renal failure in 2,heart failure in 2,cerebral infarction in 1,and hemorrhagic shock in 1.The causes of death which were related to heart,kidney and lung were in 10,6 and 2,respectively.The causes of death which were directly due to heart failure,sudden cardiac death,renal failure,respiratory failure,cerebral infarction and hemorrhagic shock were in 4,1,2,1,1 and 1,respectively.The main causes of death were multible organ failure,heart failure and acute renal failure,which accounted for 73.33% of all deaths.In this series the overall perioperative mortality was 3.11% (15/483),Operative mortality was 1.47% (6/407).Conclusions The influencing factors and the function of organs were closely correlated with the causes of death. To reduce the perioperative mortality of PAD,it is necessary both to intervene in the influencing factors and to monitor and treat the dysfunction of vital organs.

In color flow imaging systems, the ultrasound Doppler signal scattered from blood is heavily corrupted by the strong clutter signal reflected from the slow-moving muscular tissue. Moving target indicator (MTI) is a key technique of rejecting the clutter signal and detecting blood flow. To improve the performance of detecting blood flow, a new MTI scheme is proposed in this paper. It consists of a pre-filter, a clutter weak-rejector and a 2-order AR estimator. After the processing of pre-filtering and clutter weak-rejection, the strong clutter signal is effectively eliminated and its strength is comparable with blood flow. Under such condition, the optimal performance can be attained by the 2-order AR estimator. It is illustrated in the simulation that, compared with the data from traditional methods, the blood flow parameters are estimated with smaller deviation and the lower speed flow is detected.

In order to test the performance of wall filters, we propose a method for simulation of Hybrid Doppler testing signal, which adopts a rectangular power spectrum. In the method, the parameters of clutter, blood flow and system noise can be adjusted with flexibility. The problem about choosing model parameters is discussed as an emphasis. Several reasonable and typical parameter combination patterns are presented. Furthermore, an example is given to explain the process of choosing the parameters and testing the wall filter performance.

This study was aimed to establish a method for the rapid content determination of Ixerin Z and 11,13α-dihydroixerin Z in Ku-Die-Zi (KDZ) injection by UPLC-ESI-MS/MS. The separation was performed on a Waters ACQUITY BEH C18 column (2.1 mm × 50 mm, 1.7μm) by using a gradient elution with the mobile phase of acetonitrile-water at the flow rate of 0.4 mL·min-1. The column temperature was set at 40℃. Multi-reaction moni-toring (MRM) scanning was employed for quantification in ESI negative mode. The results showed that two sesquit-erpene lactones in KDZ injection were totally separated within 2 min. The linear range of Ixerin Z was 5.70-182.50 ng·mL-1, and the linear range of 11,13α-dihydroixerin Z was 4.60-131.25 ng·mL-1. The correlation coefficient r was more than 0.999 0. The recovery rates (n = 6) were 98.18% and 97.52%, with RSDs < 1.5%. The established method was successfully applied for simultaneous content determination of Ixerin Z and 11,13α-dihydroixerin Z in 6 batches of KDZ injection from 2 factories, which had some variations on the content determination results. It was concluded that the method was rapid, accurate and sensitive, which can be used for the content determination of two sesquiterpene lactones in KDZ injection.
