Objective To research the mechanisms and the link of therapy and the optimal dosage of Tongru Sanpitang on hyperplasia of mammary glands in model rats. Methods Rats were randomly divided into 6 groups:negative contronl group, model group, Rupixiao Tablets group and Tongru Sanpitang low, middle, high dose group. Model was made with complex method of Progesterone and Estradiol benzoatehad injected into abdominal. In the middle of experiment, rats were given different drug respectively. Estradiol, follicle stimulating hormone, luteinizing hormone, the expression of estrogen receptor, weight of the ovary and uterus and visceral coefficient were determined. Results Follicle stimulating hormone, luteinizing hormone, the expression of estrogen receptor in medicine group decreased. The ovary and uterus in electron microscope, weight of organs and organ coefficient were improved. Conclusion Tongru Sanpitang may adjust reproductive endocrine function by decreasing sensitivity of mammary glands to estradiol and adjust whole function in the treatment of hyperplasia of mammary glands. There are dose-effect relationship.

Objective: To explore whether the Cognitive-Behavior Training is feasible and effective in promoting the class attention behavior of a primary student. Methods: The subject was received 4 times of Cognitive-Behavior Training. Her class inattention behaviors were compared before and after the training. Results: (1) During training period, the frequencies of class inattention behavior reduced significantly from 8 times in one session to less than 2 times in average; (2) the class inattention behavior during follow up was a little more frequent than that during training, but not statistically significant.Conclusion: The Cognitive-Behavior Training is feasible and effective in promoting the class attention behavior of the case; the self- instructional training based on behavioral corrective technology may have longer effect than the behavioral technology.

Objective:To explore the value of two-dimensional speckle tracking echocardiographic imaging (2D-STI) for assessing partial and global left ventricular functional changes at pre-and post-percutaneous coronary intervention (PCI) in patients with chronic total coronary occlusion.
Methods:Echocardiograph was conducted in 23 chronic total coronary occlusion patients at pre-PCI and 1 day, 3, 6 months post-PCI to examine left ventricular ejection fraction (LVEF), meanwhile 2D-STI was applied to obtain the global longitudinal strain (GLS) value of left ventricle.
Results:In all 23 patients, for LVEF, compared with pre-PCI (59.29±12.15)%, it was increased at 3 and 6 months post-PCI (60.00±12.35)%and (61.37±11.8)%respectively, all P<0.05;for GLS value, compared with pre-PCI (-12.77d wit )%, it was decreased at 1 day and 3, 6 months post-PCI (-13.23ecrea)%and (-15.67ecrea)%, (-16.97ecrea)%respectively, all P<0.05.
Conclusion:PCI could effectively improve left ventricular function in patients with chronic total coronary occlusion, 2D-STI technology may quantitatively assess those changes at the early stage.

A rapid and accurate determination method of lipids in microalgae plays a significant role in an efficient breeding process for high-lipid production of microalgae. Using low field nuclear magnetic resonance (LF-NMR), we developed a direct quantitative method for cellular lipids in Chlorella protothecoides cells. The LF-NMR signal had a linear relationship with the lipid content in the microalgae cells for both dry cell samples and algal broth samples (R2 > 0.99). These results indicated that we could use this method for accurate determination of microalgal lipids. Although LF-NMR is a rapid and easy lipid determination method in comparison to conventional methods, low efficiency would limit its application in high throughput screening. Therefore, we developed a novel combined high throughput screening method for high-lipid content mutants of C. protothecoides. Namely, we initially applied Nile red staining method for semi-quantification of lipid in the pre-screening process, and following with LF-NMR method for accurate lipid determination in re-screening process. Finally, we adopted this novel screening method in the breeding process of high-lipid content heterotrophic cells of C. protothecoides. From 3 098 mutated strains 108 high-lipid content strains were selected through pre-screening process, and then 9 mutants with high-lipid production were obtained in the re-screening process. In a consequence, with heterotrophical cultivation of 168 h, the lipid concentration could reach 5 g/L, and the highest lipid content exceeded 20% (W/W), which was almost two-fold to that of the wild strain. All these results demonstrated that the novel breeding process was reliable and feasible for improving the screening efficiency.

A method for measuring 13C isotopic abundance of intracellular metabolites of Saccharopolysporaerythraea by ultra-high performance liquid chromatography (UPLC)-triple quadrupole mass spectrometry was established.First, the chromatographic conditions of UPLC were optimized, and then the MS conditions such as unique tube lens voltage, collision energy, and ion pair were optimized.On the bases of length of the parent and daughter ions carbon chains and whether the daughter ions contain 13C atoms, the one-to-one method, one-to-many method and SIM method were established for measuring 13C isotopic abundance.Then these methods were used to measure naturally labeled intracellular metabolite standards and 13C labeled samples, and according to the gap between the experimental value and the theoretical value, the best method was established for each metabolite of different characteristics.The results showed that one-to-one method was most effective for measuring the metabolites of daughter ions not containing 13C atoms represented by sugar phosphates, one-to-many method was the best for measuring the metabolites of both parent and daughter ions containing 13C short carbon chains represented by carboxylic acids, SIM method could play a role in measuring the metabolites of both parent and daughter ions containing 13C long carbon chains represented by coenzyme A.This method had a good measurement precision and could be applied to the measurement of Saccharopolysporaerythraea intracellular metabolites, which contributed to the consequent study of metabolic mechanism and the efficient expression of erythromycin.

Based on the optimized technology on 50L scale, B subtilis 754# was used to manufacture guanosine on pilot scale (12M 3) and plant scale (100M 3) to give the production of 29 4g/L and 21 4g/L successively Through scale down the process of plant scale to pilot scale, based on the theory of dynamic metabolic flux, DO was found to be another key factor that limited the scale up process After conquering the DO limitation, the optimized technology was successfully scaled up to plant scale and the production was further increased by 18% to 25 2 g/L

Objective To investigate the effects of N - acetylcysteine (NAC) on apoptosis and the expressions of Fas/FasL mRNA in lung tissue of rats with paraquat - induced acute lung injury.Methods Forty five male SD rats were randomly (random number) divided into normal control group,paraquat (PQ) group,and NAC treatment group.The rat model of acute lung injury was made with 2％ PQ induction in dose of 25 mg/kg injected,and NAC was injected into the PQ poisoning rats (200 mg/kg) 30 minutes after PQ administration in NAC treatment group.In the control group,equal amount of saline instead was injected into the rats.Apoptosis was detected by using TUNEL method and the expressions of Fas/FasL mRNA were evaluated by using reverse transcription polymerase chain reaction (RT- PCR),and the levels of Fas/FasL protein were detected by using western blot analysis.Results Compared with control group,cell apoptosis and expressions Fas/FasL mRNA in PQ group were significantly different ( P ＜ 0.05 ).Compared with PQ group,cell apoptosis and expressions Fas/FasL mRNA in NAC group were significantly decreased,were significant lower (P ＜ 0.05).Conclusions NAC inhibited apoptosis in lung tissue of rats with paraquat induction by regulating the activation of Fas/FasL systems.
