Objective To investigate the useful parameters of transthoracic echocardiography (TTE) for the diagnosis of stroke subtypes in patients with acute cerebral infarction.Methods One hundred and one acute ischemic stroke patients met all of the following criteria including ≥50 years of age,normal sinus rhythm on admission,and transesophageal echocardiography (TEE) within 7 days from the onset.The clinical significance of the TEE parameters on admission was examined for identifying intracardiac thrombus formation as follows; left atrial dimension,left ventricular end-diastolic dimension,percentage fractional shortening,left ventricular mass index,ratio of the transmitral inflow velocities (E/A),and the deceleration time of the E wave.Results There were 28 patients with E/A ≥ 1.0 (70 ± 12) years old and 73 with E/A ＜ 1.0 (73 ± 10) years old.No patients showed pulmonary congestion on chest radiography.There were no significant differences in age,TTE parameters,and plasma levels of brain natriuretic peptide between the two groups.Patients with E/A≥ 1.0 had higher incidence of left atrial appendage (LAA)thrombus formation and/or spontaneous echograhic contrast than those with ＜ 1.0 (25.0％ vs 5.5％,x2 =7.95,P ＜0.01).A significant relationship was found between E/A and emptying flow velocity of the LAA (r =-0.569,P ＜0.01).Multivariate logistic regression analysis showed E/A was an independent predictor for LAA thrombus (risk ratio 1.531 per0.1 increase,95％ confidence interval 1.129-2.076,P =0.0002).Conclusions Increased level of E/A on admission was associated with the occurrence of left atrial appendage thrombus formation in patients with acute ischemic stroke.

To observe the effect of autologous stem cell transplantation in diabetic retinopathy.
●METHODS:Totally 58 cases (116 eyes) who underwent autologous stem cell transplantation were confirmed as no diabetic retinopathy (18 eyes), mild non-proliferative diabetic retinopathy (NPDR) (41 eyes), mid-level NPDR (51 eyes); severe NPDR (6 eyes) by ophthalmoscope directly or indirectly and fluorescence fundus angiography (FFA ). Follow - up was 6 - 12mo, the changes of retinopathy were observed.
●RESULTS: The total effective rate of vision and retinopathy was 84. 4%, 76. 7%. The results of severe NPDR was statistically worse than the other groups ( P <0. 05).
●CONCLUSlON: The stable blood glucose level and improved pancreatic function after autologous stem cell transplantation might be helpful in diabetic retinopathy, the long effects need to be researched further.

The effects of application of in-process quality control in Guizhi Fuling capsule production were evaluated by 192 batches data analysis. Using a statistical analysis method, each batch of data were to be counted to research for the difference between 96 samples adopting the technologies of in-process control or not. According to quality standards of Guizhi Fuling capsule, all measurements of the 192 batches of the drugs before and after the application of process control technology were analyzed, and they were within the rules. There was a significant difference between adopting the technologies of process control or not. Application of in-process control technology can improve the uniformity of lot-to-lot for Guizhi Fuling capsule.

Polydatin is a monocrystaline compound isolated from Polygonum cuspidatum Sieb. et Zucc. (Polygonaceae) with biological properties, such as anti-inflammation, anti-oxidative and nephroprotective effects. Increasing number of studies have demonstrated the protective effect of polydatin on renal ischemia reperfusion injury. However, the possible mechanisms of this protection are not fully elucidated. This study aimed to investigate the effect of polydatin on ischemia-reperfusion induced expression of toll-like receptor4 (TLR4) in rat renal tubular epithelia cells (NRK-52E), and analyze the mechanism of polydatin on TLR4 signal pathway. The cultured NRK-52E cells were incubated in three gas incubators for a period of 6 h at hypoxia and 24h at reoxygenation to simulate the ischemia-reperfusion injury in vitro. TLR4 mRNA level was analyzed by real-time-PCR, and the protein expression of TLR4 and NF-κB by Western blotting, while TNF-α and IL-1β proteins expressions were detected by ELISA. Polydatin downregulated I/R induced mRNA and protein expressions of TLR4, and decreased the protein expression of NF-κB, TNF-α and IL-1β. The TLR4 blocker partially antagonized the effect of I/R on NF-κB signaling, and such inhibitory effect was markedly enhanced by polydatin. In the present study, polydatin protects NRK-52E cells from I/R injury possibly by relieving the inflammatory response through regulation of TLR4/NF-κB signaling pathway.

The study aims to develop a rapid, sensitive and specified method of liquid chromatography with heated electrospray ionization tandem mass spectrometry (LC-HESI/MS/MS) for simultaneous determination of amlodipine, benazepril and benazeprilat in human plasma using amlodipine-d4 and ubenimex as internal standards (ISs). Selected reaction monitoring (SRM) with heated electrospray ionization (HESI) was used in the positive mode for mass spectrometric detection. Analytes and ISs were extracted from plasma by simple protein precipitation. The reconstituted samples were chromatographed on a C18 (100 mm x 4.6 mm, 5 microm) column with mixture of methanol-acetonitrile-5 mmol.L- ammonium acetate-formic acid (30 : 30 : 40 : 0.1) as mobile phase at a flow rate of 0.6 mL.min-1. The standard curves were demonstrated to be linear in the range of 0.02 to 6.00 ng.mL-1 for amlodipine, 0.2 to 1,500 ng.mL-1 for benazepril and benazeprilat with r2>0.99 for each analyte. The lower limit of quantitation was identifiable and reproducible at 0.02, 0.2 and 0.2 ng mL-1 for amlodipine, benazepril and benazeprilat, respectively. The intra-day and inter-day precision and accuracy results were within the acceptable limit across all concentrations. The plasma samples were stable after four freeze-thaw cycles and being stored for 93 days at -20 degrees C. The method was applied to a pharmacokinetic study of a fixed-dose combination of amlodipine and benazepril on Chinese healthy volunteers.
