To discuss the protective effect of aralosides (AS) on I/R-induced rat myocardial injury. The adult rat ventricular myocyte ischemia model was established through perfusion with sodium lactate perfusate and reperfusion with Ca(2+) -containing Tyrode's solution simulation. The cell contraction and ion concentration synchronization determination system was applied to detect the effect of AS on single I/R cell contraction and Ca2+ transients. According to the findings, AS could increase resting sarcomere length, contraction amplitude, ± dL/dt(max), calcium transient amplitude and speed of post-reperfusion myocardial cells (P < 0.05, P < 0.01), and decrease in time for achieving 90.0% of maximum relaxation, time for achieving peak value, resting calcium ratio, contraction period [Ca2+] i, time for achieving 50.0% of maximum relaxation and attenuation rate of intracellular calcium transient (P < 0.05, P < 0.01). Therefore, it is suggested that AS improved the post-reperfusion cell contraction and injury of calcium homeostasis.

OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.

RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.

CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

Objective To investigate the relationship between the expression of decay receptor 3 (DcR3) and the eliniealpathological parameters in human gastric carcinoma. Methods The expression of DcR3 was examined by RT-PCR in a series of 41 human primary gastric carcinomas and 41cases of normal tissue adjacent to tumor. Multiple clinical pathological factors were analyzed according to their relation with the expression of DcR3. Results The positive rate of expression of DcR3 was 56 %(23/41) in human gastric carcinoma. The expression of DcR3 in gastric carcinoma was significantly higher than that in normal tissues adjacent tumor. The expression of DcR3 was significantly correlated with different degrees of differentiation, lymph node metastasis and TNM staging (P <0.10), but there was no significant difference in DcR3 and other clinical pathological features such as tumor position and invasion depth (P>0.10). The multiple linear regression equation was Y=0.432-0.208X1+0.098X2+0,086X3. Conclusion DcR3 expression can be highly found in gastric carcinoma. The abnormal expression of DcR3 may promote tumorigenesis and progression. DcR3 may be important in evaluating the tumor differentiation, infiltration depth, lymph node metastasis and TNM staging of human gastric carcinoma.

Because of irregular shapes of Chinese herbal pieces, we simplified the previously deduced general extraction kinetic model for TCMs, and integrated particle diameters of Chinese herbs that had been hard to be determined in the final parameter "a". The reduction of the direct determination of particle diameters of Chinese herbs was conducive to increase the accuracy of the model, expand the application scope of the model, and get closer to the actual production conditions. Finally, a simplified model was established, with its corresponding experimental methods and data processing methods determined. With total flavonoids in Scutellariae Radix as the determination index, we conducted a study on the adaptability of total flavonoids extracted from Scutellariae Radix with the water decoction method in the model. The results showed a good linear correlation among the natural logarithm value of the mass concentration of total flavonoids in Scutellariae Radix, the time and the changes in the natural logarithm of solvent multiple. Through calculating and fitting, efforts were made to establish the kinetic model of extracting total flavonoids from Scutellariae Radix with the water decoction method, and verify the model, with a good degree of fitting and deviation within the range of the industrial production requirements. This indicated that the model established by the method has a good adaptability.

In this paper, a novel and simple RP-HPLC method for the determination of related substances of tiopronin for injection was described. The RP-HPLC analysis was performed on a C18 column, with acetonitrile-0. 1% phosphoric acid(8 ∶92), mobile phase in isocratic mode at a rate of 1. 0 mL/min. The photodiode array detector was set at 210 nm. Seven related substances were detected and the structures were characterized by mass spectrometry. The method showed great suitability, specificity and excellent linearity over the concentration range of 0. 3 to 50 μg/mL(r≥0. 999), and the limits of detection and quantitation were found to be 0. 10 and 0. 31 μg/mL, respectively. The accuracy of the method determined by the entire mean recovery ranged from 98. 7% to 103. 7%. The intra-and inter-day precision was satisfactory(RSD≤4. 4%)and robust(RSD≤6. 4%). And this method was successfully applied for the determination of related substances of tiopronin for injection, which revealed the retention of sulfhydryl compounds and glycine analogues on the RP-HPLC and the effect of the pH value of the mobile phase on the chromatographic behavior of the analytes.
