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.

Objective To investigate the difference between the blood pressure readings between sitting and supine position,and to study the factors that associated with the sitting-supine blood pressure difference in patient with diabetes.Methods We measured the sitting blood pressure first then followed by the supine pressure in 356 diabetic patients,using a standard mercury sphygmomanometer.Patient's body weight,height and blood glucose levels were also measured.Results SBP and DBP were significantly higher in the supine position than in sitting position in diabetic patients(by 3.5?7.6/1.5?4.9 mm Hg,P

OBJECTIVETo observe the inhibitory effects of crescent euphorbia on tumor growth, immunoregulation, the side effect on the mice blood system, cell cycle and to investigate its effect on apoptosis of tumor cells.

METHODCrescent euphorbia was administered gastrally to C57BL/6J mouse implanted with Lewis lung cancer for 12 days. Inhibition on tumor growth, immunoregulation,the side effect on the mice blood system and cell cycle were observed and its effect on apoptosis of lung cancer cells were investigated.

RESULT(1) Inhibitory rates of crescent euphorbia at doses of 7.5, 15, 30 g x kg(-1) and 60 g x kg(-1) were 0.61%, 16.93%, 32.81% and 58.26% respectively, significant differenel with those of controls at doses of 30 g x kg(-1) and 60 g x kg(-1)(P < 0.05). (2) Although no effect on thymus index in normal mouse at all dose of crescent euphorbia was found, spleen index in tumor-bear mice was reduced significantly at dose of 60 g x kg(-1)(P < 0.05). (3) No side effect on the miceblood system was found. (4) The percentage of S phase of cell cycle was increased in the group of crescent euphorbia at dose of 30 g x kg(-1), 60 g x kg(-1) and the apoptotic rate was (16.43 +/- 18.69)% and (24.37 +/- 15.48)% by flow eytometry (P < 0.05). The apoptotic index (AI)of these two groups were (4.00 +/- 7.50)% and (5.93 +/- 5.96)% by TUNEL, however apoptosis was found in the group at doses of 60 g kg(-1) (P < 0.01).

CONCLUSIONCrescent euphorbia can inhibit the growth of Lewis lung cancer in mice, no side effection for the mice blood system and the effect might be associated with induction of apoptosis on cancer cells.

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.

Chelating ligand method has been used to synthesize baicalin-metal (Ni2+, Co2+, Cu2+) complexes (BMC). The composition and structure of BMC were characterized by the element analysis, ultraviolet spectrum (UV), infrared spectrum (IR), mass (MS) and thermal gravitational analysis (TGA). MTT was used to analyze the effects of BMC on SMMC-7721 cell proliferation. PI staining method and Annexin-V/FITC double staining method were used to analyze the effects of BMC on the cell cycle and apoptosis of SMMC-7721 cell. Fluorescence quantitative RT-PCR was used to analyze the expression of BMC on Bcl-2 gene and Bax mRNA, flow cytometry was used to analyze BMC on the expression of Bcl-2 protein and Bax protein. The antineoplastic activity and mechanism of action of BMC was explored comprehensively. The results showed that three new kinds of BMC (molar ratio of 2 : 1) were successfully prepared, the complexes molecular formula are: Na2Ni(C21H16O11)2 x 10H2O, Na2Co(C21H16O11)2 x 8H2O and Na2Cu(C21H16O11)2 x 8H2O. According to the results of cell cycle and apoptosis detection, BMC stopped cells at G0/G1 phase to S phase and G2/M phase. Gene and protein detection showed that under the given concentration and time, BMC can downregulate the expression of Bcl-2 gene in SMMC-7721 cells, and significantly decrease the expression of Bcl-2 protein, at the same time, with the increase of expression of Bax gene, the Bax protein's expression increased significantly. Which indicates that BMC restrain cell proliferation and cell apoptosis by stopping cell cycle, reducing the expression of Bcl-2 and increasing that of Bax; The anti-tumor activities of three kinds of complexes were: baicalin-copper (BC-Cu) > baicalin-cobalt (BC-Co) > baicalin-nickel (BC-Ni) > baicalin (BC), showing the dose-response relationship.
