Shan Qi soy has busting bags, bacteria sum overproof, continue acidification and other problems occasionally during the storage. It's probably caused by the Lactobacillus continue growth in the soy. We tried expounding the relationship between growth and producing acid when Lactobacillus growing in the thin fermented material.

Objective To evaluate the clinical application of transendoscopic Doppler ultrasonogra-phy in various gastrointestinal diseases. Methods Transendoscopic Doppler ultrasonography was performed in 59 patients with various gastrointestinal diseases. Results The Doppler signals were detected beneath the peptic ulcer base in 29 of 39 patients (74. 4% ) . For acute ulcer bleeding and non - bleeding, the Doppler - positive rates were 87. 5% and 65. 2% , respectively, and the measured depth of vessels were 0. 49 mm and 0. 65mm (P

Objective To establish the cell model of restenosis in vitro and investigate the effects of fenofibrate on the prevention and treatment of the restenosis.Methods Human umbilical vein endothelial cells(HUVECs) were cultured in vitro.The study was designated to 5 groups:(1) control group,(2) LPC group,(3) low-concentration fenofibrate(10 ?mol/L) group,(4) midium-concentration fenofibrate(50 ?mol/L) group,and(5) high-concentration fenofibrate(100 ?mol/L) group.Proliferation and apoptosis of HUVECs were assessed by MTT assay,flow cytometry(FCM) and fluorescence microscopy respectively.Results Compared with the control group,LPC could inhibit the growth and induce apoptosis of HUVECs as well as decrease NO production in HUVECs.Fenofibrate could increase the proliferation and decrease the apoptosis of HUVECs,and also enhance NO production of HUVECs.Conclusion Fenofibrate could improve proliferation and reduce apoptosis and enhance NO production of HUVECs through lysophosphatidylcholine,which may be an important route for fenofibrate to prevent and treat the restenosis after percutaneous coronary intervention.

Objective To observe the reparative response and expression of basic fibroblast growth factor (bFGF) protein in the rotator cuff subjected to subacromial impingement. Methods Subacromial impingement of the infraspinatus tendon was experimentally created in 50 male SD rats by thickening the undersurface of the acromion with one platelike bony transplantation of the ipsilateral scapular spine. The contralateral shoulders that had undergone a sham operation were used as controls. The rats were sacrificed at 3, 7, 14, 28, and 56 th day, the whole shoulder joint was removed for detecting bFGF protein and the reparative response in the impinged infraspinatus tendon. Computer image analysis system were used to monitor the expression intensity and numbers of positive cells of bFGF protein. The OD scores and the size of area represent the expression intensity and numbers of positive cells respectively. Results All rats with experimental subacromial impingement showed an infraspinatus tear on the bursal side of the tendon. The shoulders in the control group were found intact without any alteration. There was proliferating cells in the fragmented tendons and vascularised connective tissue covering the area of ruptured area, whose source was the subacromial bursa. Few tenocytes and bursal cells expressed bFGF protein in unwounded tendons. In contrast, tendons subjected to impingement exhibited an increased signal for bFGF protein in both resident tenocytes concentrated along the epitenon and infiltrating fibroblasts and inflammatory cells from the subacromial bursa. Conclusion The bFGF protein is upregulated during tendon healing and the subacromial bursa is the main source of both bFGF secreting and rotator cuff repair; one should preserve as much as possible the subacromial bursa.

Objective:To do the research on the layout and construction preparation for 3.0T high-field nuclear magnetic resonance equipment room, greatly shorten the construction time and save money for hospital by the safe and convenient usage. Methods: According to the specific characteristics of hospital sitting in full consideration of transportation and distribution, ventilation, bearing, electromagnetic interference and so on, we implement gradually, were ready to work in the construction. Results: Computer room location requirements bearing within 10 tons, magnets, center of 3 m in ferromagnetic material to do assessment, and moving around the car and the transformer must be beyond 3G line, required a special transformer and the capacity of more than 150 kVA. Equipment grounding resistance is less than 2 ohms, shielding room of insulation is greater than 1000 ohms. Super tube is higher than 3.8 m above the ground, there be no air conditioning air inlet. Water-cooled machine well ventilated, northern region need to get the winter outdoor antifreeze. Exhaust air change per hour between magnet design of not less than 12 times. Conclusion: Hospital construction for large equipment and ancillary equipment is installed in the process of each link to match reasonably, pay attention to the collaboration between different units and at the same time. Reasonable equipment layout and construction preparation is the guarantee of equipment installation smoothly.

Objective To study the characteristic of cognitive function impaired and its relationship with the psychiatric symptoms in patients with first-episode schizophrenia.Methods 43 first-episode male schizophrenia patients diagnosed with DSM-Ⅳ were recruited in the study and received the atypical antipsychotics treatment 8weeks.The total score and sub-scores of Chinese Cognitive Ability Scale (CCAS)were obtained for all the patients pre-and post-treatments,and the patients were also assessed by the Positive and Negative Syndrome Scale (PANSS).Results The differences of the intelligence quotient(IQ) and its cognitive function factors between pre-and post-treatment of the patients were significant(P＜ 0.01).The total IQ score (85.7 ± 11.5),learning ability (17.9± 2.3),reasoning ability (16.1 ± 3.4),processing speed (16.9 ± 2.1),working memory (13.8 ± 2.6),space/calculate (17.5 ± 2.9),verbal IQ (86.8 ± 11.7),performance IQ (83.9 ± 12.4) before treatment and cognitive score (97.6 ± 14.3) as well as cognitive function factor (learning ability (20.1 ± 2.9),reasoning ability (18.9± 3.1),processing speed (19.7 ± 1.8),working memory (15.7 ± 2.5),space/calculate (20.8 ± 2.5),verbal IQ (98.3 ± 13.7),performance IQ (95.8 ± 14.6) after treatment,there were significant differences pre-and posttreatment (P ＜ 0.01).The difference of IQ pre-and post-treatment was significantly correlated with that of total score and positive score of PANSS(r =0.596 or 0.783).Conclusions (1) This finding supports that the cognitive function impairment exists in the early stage of schizophrenia.(2)The typical antipsychotic drugs can improve the cognitive function impairment and psychiatric symptoms of schizophrenia.(3) The cognitive function impairment of schizophrenia has significant relation to the positive symptoms,but no relation to the negative symptoms.

This study aims to observe different factors which affected the bionic enzymatic hydrolysis of icariin into baohuoside I and to optimize the reaction conditions in order to provide research foundation for building a novel bionic enzymolysis drug delivery system. To simulate the environment in vivo, 37 degrees C was set as the temperature and artificial intestinal juice and gastric juice were selected as the buffer solutions. Taking the conversion of baohuoside I as index, the effects of the kinds of enzyme, enzyme activity, substrate concentration, reaction time, pancreatin in artificial intestinal juice and surfactant on the conversion of baohuoside I were investigated. The results showed that cellulase, beta-glucosidase and snailase were all inactive in artificial gastric juice and no baohuoside I generated. Pancreatin in artificial intestinal juice couldn't significantly influence the activity of beta-glucosidase or snailase (P > 0.05), but noticeably decrease the activity of cellulase (P < 0.05). In artificial intestinal juice, the conversion of baohuoside I was highest by using beta-glucosidase, and the optimum reaction conditions were determined as follows: enzyme activity 10 U x mL(-1), substrate concentration 1 mg x mL(-1), 3 g x L(-1) rhamnolipid and reaction time 3 h. Under this condition, the conversion of baohuoside I was 99.8%.
