Licorice seedlings were taken as experimental materials, an experiment was conducted to study the effects of exogenous sucrose on growth and active ingredient content of licorice seedlings under NaCl stress conditions. The results of this study showed that under salt stress conditions, after adding a certain concentration of exogenous sucrose, the licorice seedlings day of relative growth rate was increasing, and this stress can be a significant weakening effect, indicating that exogenous sucrose salt stress-relieving effect. The total flavonoids and phenylalanine ammonia lyase (PAL) activity were significantly increased, the exogenous sucrose can mitigated the seedling roots under salt stress, the licorice flavonoid content in the enhanced growth was largely due to the activity of PAL an increased, when the concentration of exogenous sucrose wae 10 mmol x L(-1), PAL activity reaching a maximum, when the concentration of exogenous sucrose was 15 mmol x L(-1), PAL activity turned into a downward trend, the results indicating that this mitigation has concentration effect. After applying different concentrations of exogenous sugar, the contents of liquiritin changes with the change of flavonoids content was similar. After applying different concentrations of exogenous sucrose, the content of licorice acid under salt stress was higher than the levels were not reached during salt stress, the impact of exogenous sucrose concentration gradient of licorice acid accumulation was not obvious.

OBJECTIVE: To discuss the methods for clinical rational use and state regulation of high risk Traditional Chinese Medicine Injections (TCMIs) based on our hospital TCMIs analysis and literature review. METHODS: By analyzing the prescription rates and amount percentage of TCMIs in emergency, outpatient and inpatient departments of our hospital as well as literature searching to learn the current state and conditions of TCMIs. RESULTS: Utilities of TCMIs from 2012 to 2014 shows an elevated tendency with percentages of 1.19%, 1.34% and 1.40% respectively. Emergency, ENT and internal neurology departments oi outpatient are the top 3 on prescription rates and amount percentage. Inpatients' order rates of TCMIs are 0.79%, 0.80% and 0.79% respectively. Oncology (20%-26%), emergency (12%-14%) and internal neurology (10%-11%) departments are the top 3 amount rates in ordering TCMIs,however, the department of TCM only account for 4%-5%. The percentages of TMCIs amount vs. annual total drug amount during 2012-2014 are 2.10%, 2.07% and 2.14%, which is lower than literature reports. CONCLUSION: Not all the TCMIs use in our hospital are rational, mainly reflects in non-TCM doctors having used the most amount of TCMIs. Therefore, the TCM consultation policy should be established to support TCMI rational utility, TCMIs labels should be strictly regulated and the quality standards of TCMIs should be elevated to ensure the safety and effectiveness. All above efforts should be done to protect and develop TCMI, an innovation of TCM.

Objective To investigate new cases of endemic cretinism in high-risk areas of Inner Mongolia, the prevalence of endemic goiter, the implementation of comprehensive measures, and to provide scientific basis for developing control strategies against iodine deficiency disorders (IDD). Methods In 2007 and 2008, a search for new cretin cases was conducted among children under the age of 10 in 11 historical serious epidemic cretinism prevalent areas of Songshan district, Keshiketeng qi, Kalaqin qi, Zhalaite qi, Zhuozi county,Liangcheng county, Qingshuihe county, Helin county, Dongsheng district, Zhungeer qi and Yinjinhuoluo qi. Three to 5 towns were selected in each qi(county, district) and 3 to 5 village primary schools were selected in each town.One hundred and twenty to 200 children aged 8 to 10 were selected in each school to inspect thyroid by B ultrasound and palpation and to test intelligence and urinary iodine. Two villages were selected in each town and 30 households were selected to determine urinary iodine of housewives and salt iodine. Results A total of 56 cases of suspected cases of endemic cretinism were found from the 11 counties but no case was confirmed. The goiter rate of children aged 8 to 10 was 5.2% (309/5922) by palpation and 4.3% (252/5922) by B-ultrasound. The median urinary iodine of children aged 8 to 10 was 241.5 μg/L, and urinary iodine was 100 to 300 μg/L, accounted 65.9%(3901/5920). Median urinary iodine of the 9 Qis(counties, districts) was in the range of 200 and 300μg/L.Higher than 5% of the 11 Qis(counties, districts) with urinary iodine lower than 50 μg/L was zero. Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 1. The median urinary iodine of housewives was 225.6 μg/L, and lower than 50 μg/L accounted for 2.2%(35/1597). Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 4. A total of 2109 households were investigated and 97.45%(2055/2109) of them ate iodized salt and 2.55%(54/2109) of them ate non-iodized salt. Conclusions In the 11 investigated counties, goiter rate of children has decreased to less than 10%, and no new cretin was found. It could be concluded that the fulfillment of prevention and control of IDD is effective. The iodine nutrition of children and women of childbearing age is in an adequate level. The coverage rate of iodized salt has maintained at a higher level, the sales network is sound, the salt price is reasonable and salt is easy to get and the children's intelligence is protected effectively. But, the health education about IDD is still weak, need to be reinforced.

MATERIALS: Seven Chinese mini-pigs with 1-7 days old and of either gender were provided by Experimental Animal Center, the Third Military Medical University (certification: F99017). The animal disposal accorded to the ethical standard. Tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) kits were purchased from Jingmei Bioengineering Company, China; polysulfone membrane hollow fiber reactor by Shanghai Dehong Biomaterial Institute, China; Cellco culture-circular artificial capillary culture system by Spectrum Company, USA; seven plasma exponents were taken from admission patients with chronic severe hepatitis during plasma exchange. All patients provided the informed consent, and the animal experiment was conducted with confirmed consent by the local ethics committee.METHODS: This study was performed at the General Infectious Disease Institute, Southwest Hospital, the Third Military Medical University of Chinese PLA from January 2004 to July 2005. ① Experimental procedure: The experimental pigs underwent ablactation at 12 hours before experiment, and then hepatocytes were separated after cleaning their fur. An enclosed system was composed of polysulfone membrane hollow fiber reactor and Cellco culture-circular artificial capillary culture system, which were connected with oxygen-carbon dioxide diffusion tube and media holding pond. Interface of external cavity was blocked with clean rubber tampon. The separated hepatocytes underwent spheroid culture by using magnetic stirring method, and then they were inoculated in the external cavity of polysulfone membrane hollow fiber reactor. Next, 200 mL plasma from severe hepatitis patients was added in media holding pond and circled from internal cavity of reactor to media holding pond at the speed of 80 mL/min. ② Experimental evaluation: 2 mL liquid circulation separately collected from internal cavity of reactor at 0, 2, 4 and 6 hours after circulation was used to measure level of ammonia in supernatant by using glutamic dehydrogenase-violet method. In addition, content of total bilirubin was detected by using automatic biochemistry analyzer, prothrombin time by using automatic blood coagulometer, and TNF-α and TGF-β1 were detected according to the kits. MAIN OUTCOME MEASURES: Effects of polysulfone membrane bioreactor on ammonia, bilirubin, prothrombin time, TNF-α and TGF-β1 in plasma of patients with severe hepatitis.RESULTS: ① Measurement of ammonia, total bilirubin and prothrombin time in patients with severe hepatitis: Level of ammonia decreased persistently, in particularly, the decrease was obvious from 0 to 2 hours, and then, it was decreased slowly. While, level of total bilirubin was also decreased persistently, and it was significantly lower at 6 hours than that at 0 hour (P < 0.05). Moreover, prothrombin time was decreased persistently, and it was significantly lower at 6 hours than that at 0 hour (P < 0.05). ② Measurement of TNF-α and TGF-β1 in patients with severe hepatitis: Contents of both TNF-α and TGF-β1 decreased persistently, and they were significantly lower at 6 hours than those at 0 hour (P < 0.05). CONCLUSION:Polysulfone membrane bioreactor experimental system can clear noxious substance of small molecules in plasma of patients with severe hepatitis, supply beneficial components, and decrease levels of cytokines. Therefore, it can be regarded as the bioartificial liver reactor.
