Background Research showed that the morbidity rate of primary angle closure glaucoma (PACG) in Mongolian population is 3.02 times more than Han nationality population.To understand the cause and mechanism of PACG in Mongolia is of an important significance.Objective This study was to investigate the pathogenesis of Mongolian PACG.Methods Thirty-two eyes of 32 PACG patients in Mongolia and 40 eyes of 40 PACG patients of Han peoples were included in Inner Mongolia Autonomous Region People's Hospital according to the diagnosis criteria of glaucoma group of Chinese Medical Ophthalmology Association (version 1987),and 13 eyes of 13 normal Mongolia and 17 eyes of 17 normal Han peoples who suffered with ocular truma were recruited as controls.Intraocular pressure(IOP) was measured before surgery.The trabecular meshwork tissue was obtained from all the eyes during the operation.Annexinv-FITC/PI double staining was performed and the apoptosis rate of trabecula cells was tested with flow cytometry.Written informed consent was obtained initial of the study.Results The IOP value in Mongolia PACG group,Han PACG group,Mengolia normal group and Han normal group was (35.97±7.11)mmHg,(38.70± 6.82) mmHg,(14.69 ± 2.91) mmHg and (13.59 ± 2.91) mmHg,respectively,showing a significant difference among the 4 groups(F=106.144,P=0.000),and the IOP was significantly higher in the Mengolia PACG group and Han PACG group than the normal groups(P＜0.05).The apoptosis rate of the cells was (7.14±0.67)％,(5.40±0.69) ％,(5.86±0.91) ％ and(2.29±0.65) ％ in the Mongolia PACG group,Han PACG group,Mongolia normal group and Han normal group,respectively,with a significant difference among them (F =174.888,P =0.000),and apoptosis rate of the Mongolia PACG group was significantly higher than that of the Han PACG group and the Mongolia normal group (P＜0.05).No significant difference was found between the Mongolia PACG group and the Han PACG group or between the Mongolia normal group and Han normal group (P＞0.05).The cell apoptosis rate was increased with the elevation of IOP (b =0.990,F=10.209,P =0.009) with the regression equition Y =2.788 +0.092X.Conclusions The apoptosis rate of trabecula cells in Mongolian is higher than Han people.If these results are associated with the high incidence of Mengolia PACG is worth of study.

The effects of Spirulina on intestinal microflora of diarrhea model mice were observed.Diarrhea model mice were geted by gastric perfusion ampicillin,then these mice were given different doses spirulina by gavage.Selective culture media were used to culture bifidobacteria,bacterium lacticum,enteric bacilli,enterococci,bacteroid,clostridium perfringens in feces at different times.In order to find the difference of collecting samples from feces and intestine,the quantity of detection flora in different segment of intestine were compared too.The result showed that in middle dose group and high dose group spirulina can regulate and improve intestinal flora of diarrhea model mice,and effectively shorten time from disturbance to balance.Fecal sample and intestinal contents sample both manifest a same trend,that is the quantity of bifidobacteria,bacterium lacticum in treatment recovery group is significantly higher than saline group,and enteric bacilli,enterococci,bacteroid,clostridium perfringens is significantly lower than saline group,but each index flora in intestinal contents sample has a significant difference in quantity.

ObjectiveTo observe the projections from respiratory neurons of medulla oblongata to the motor neuron pool of phrenic nerve in rat. MethodsBy using horseradish peroxidase (HRP) retrograde tracing technique after injecting HRP into phrenic nerve, retrograde labelled neurons were found in C3-C5 segment. Then, HRP was injected into the area where the phrenic motor neurons occupied, retrograde labelled neurons were found in medulla oblongata. ResultsPhrenic motor neurons locate in the C3-C5 segment ipsilaterally, occuping the intermediate portion of anterior horn and appearing typical motor neurons. Retrograde labelled neurons were found bilaterally in medulla oblongata, the neurons were located in nucleus retroambigualis (RNA), ventramedial area to nucleus retrofacialis (NRF). ConclusionThe phrenic motor neurons may receive direct projection of respiratory neuron in medulla oblongata, the projecting neurons are distributed in RNA and NRF area.

To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.
