The antioxidant activity of lycopene is highest among the current carotenoids.Recently the researches on lycopene are focused on ingredient of functional foods in the world.The fermentation production of lycopene by Streptomyces rimosus was reported first time in China.The determination methods,such as spectrophotometric method and HPLC were constructed.Using a stain Fc of Streptomyces rimosus as a original strain,a high-yield lycopene producing mutant strain Fc' was selected after UV mutation.The lycopene yield of the strain is 2.5 times higher than the original strain Fc.The optimal fermentation conditions were determined by flask experiments,and the lycopene yield of strain Fc' reached 230mg/L in flask under the optimal fermentation condition,meanwhile the Streptomyces rimosus strain could produce purer lycopene without adding any blocking agents in its fermentation process.This results lay a good foundation for lycopene commercial production by fermentation using Streptomyces rimosus.

Objective To observe the expression of cysteine rich-protein 61 (Cyr61) on renal tubular cells,to explore its effects against hypoxic induced kidney injury and the underlying mechanisms.Methods A stably Cyr61 expressed tubular cell line Cyr61-HK2 was established based on HK2 cells and recombinant Cyr61-lentivirus.BrdU incorporation assay was used for cell proliferation.The apoptosis of cells was analyzed by flow cytometry with Annexin V and propidiumiodide staining.Western bloting was used to detect the protein expression of BAD,Akt and ERK.Results (1) Cyr61-HK2 cells displayed more proliferation ability than HK2 cells.(2) Under hypoxia condition,the apoptosis of both HK2 and Cyr61-HK2 cells increased,but the apoptosis of Cyr61-HK2 cells was lesser than HK2 cells.(3) The expression of Cyr61 led to the phosphorylation of BAD,Akt and ERK on 0 h,0.5 h,1 h (all P ＜ 0.05).Conclusion The expression of Cyr61 can promote cell proliferation and dampen cell apoptosis induced by hypoxia,which may be involved in the Akt/ERK signal pathway.

Objective To investigate the clinical features and characteristic of auxiliary examination of neuralgic amyotrophy(NA).Methods8 patients with idiopathic neuralgic amyotrophy were analyzed retrospectively with literature review.Results and ConclusionAntecedent events were found before attack in 5 patients.Serious pain,which was followed by paresis and atrophy,as initial symptom,was found in 7 patients.Damage in the upper and middle trunk distribution occurred most frequently.Elevated liver enzymes were found during the early phase of their attacks in 2 patients.CSF analysis was performed in 5 patients,and mildly elevated protein was found in two.5 patients had been misdiagnosed as cervical spondylosis.After medical and/or physical therapy(6 patients with corticosteroid and physical therapy,2 only with physical therapy),all the patients had been followed up for 2～13 months.Muscle power was recovered in 67% of all the patients,partially recovered in 33%.

OBJECTIVETo assess the effectiveness and safety of traditional Chinese herbal medicine (TCHM) for chemotherapy-induced leucopenia in patients with malignant tumor.

METHODSChinese database (CNKI, VIP, CBM, Wanfang Database) and English database (Medline, Cochrane Library) were retrieved with the deadline of September 2013. Participants were cancer patients confirmed by pathology waiting for chemotherapy. We included randomized clinical trials (RCTs) testing chemotherapy plus TCHM vs. chemotherapy plus placebo, chemotherapy alone, conventional treatment, or TCHM plus chemotherapy combined with conventional treatment vs chemotherapy combined with conventional treat ment. The primary outcomes were WBC count, leucopenia incidence, and adverse reactions. Assessments of methodological quality, including randomization, allocation, concealment, blindness, dropping-out, loss of follow-ups were also conducted according to the Cochrane Handbook for Systematic Review of Interventions. Meta-analysis was performed using RevMan5. 2 Software provided by Cochrane Collaboration.

RESULTSEighty-seven RCTs (involving 8 468 patients) were included. All these studies were published in Chinese. Of these only two papers were of high quality. Methods of randomization, scheme concealment, blindness, dropping-out, loss of follow-up, samples estimation were not accurately reported in the rest RCTs. The pooled results of WBC count showed that chemotherapy combined with TCHM was generally better than chemotherapy alone [MD =0. 64 x 109/L (0.41, 0.88), P < 0.01]. Auxiliary treatment of Compound Ejiao Syrup, Diyu Shengbai Tablet, Chinese compounds for invigorating Pi and supplementing Shen during the chemotherapeutic course could elevate peripheral blood WBC counts, and decrease the incidence of leucopenia.

CONCLUSIONChinese herbal medicine might have potential effects in preventing the occurrence of leucopenia, which need to be confirmed by launching higher quality clinical trials.

Aim To investigate the effect of polysac-charide of Cistanche deserticola ( CDPS) on the impro-ving ability of synaptic plasticity in memory acquisition impairment model mice induced by scopolamine. Methods The KM mice were randomly divided into six groups:scopolamine group, control group, CDPS-treated (25, 50, 100 mg·kg-1 ) group and donepezil group. Memory acquisition impairment model in mice was established with i. p. scopolamine (4 mg·kg-1 ) only once, and orally administered CDPS (25, 50, or 100 mg · kg-1 ) daily for 6 weeks before scopolamine injection. Experimental groups were subjected to step-down test and Morris water maze test. Western blot and RT-PCR analysis were used to examine the expression of GAP-43 , SYP and PSD-95 . Transmission electron
microscope was used to observe the change of synaptic number and structures. Results CDPS (25,50,100 mg·kg-1 ) could shorten the incubation period of mice in the water maze test. Control group and CDPS-treated group swam longer in Q3 than scopolamine group. Mo-reover, CDPS (50,100 mg·kg-1 ) could significantly reduce the error times and extend the incubation period in the step-down test. The results of Western blot and RT-PCR showed that CDPS significantly improved the expression of GAP-43 at the dose of 25 ,50 mg · kg-1 and SYP at the dose of 25,50, 100 mg·kg-1 in hip-pocampus of mice. However, the biochemical assays did not reveal a significant difference in the basal hipp-ocampal levels of the PSD-95 . The ultra-thin speci-mens of hippocampus showed that the number of syn-
apse was increased in CDPS-treated group. Conclu-sions Scopolamine can induce the learning and mem-ory deficits in mice to make related protein expression abnormalities in hippocampus mice, thus this causes the change of synaptic plasticity, which leads to a change in the ability of learning and memory. And CDPS can improve the expression of SYP and GAP-43 ,
increase number of synapses, recover synaptic plastici-ty, and improve the ability of learning and memory in mice.

Objective To find out the situation of household consumption of iodized salt in Hebei province so as to provide scientific basis for prevention and control of iodine deficiency disorders(IDD). Methods According to the "national iodine deficiency disorders surveillance program (Trial)", the county (city, district) was taken as a unit, township (town) and administrative villages were selected in accordance with the principle of systematic sampling, then households were chosen by random sampling to collect their edible salt in Hebei province from 2007 to 2009. Salt iodine content was detected by direct titration method. Results A total of 48 675, 48 448 and 48 756 salt samples were collected from 2007 to 2009, respectively. The consumption rate of qualified iodized salt from 2007 to 2009 was 91.16%, 91.96% and 96.17%, respectively. There were 24.6%(41/167)and 18.0%(30/167)counties with consumption rate of qualified iodized salt under 90% in 2007 and 2008, respectively. The percentage of counties with consumption rate of qualified iodized salt above 90% was 100.0%(167/167) in 2009. In general there was a significant differences in frequency distribution of consumption rates of qualified iodized salt among the three years(H = 10.778, P ＜ 0.01 ), and the difference was found significant between 2007 and 2009 as well as between 2008 and 2009(all P ＜ 0.05), but was not significant between 2007 and 2008(P ＞ 0.05). Conclusions The consumption rate of qualified iodized salt at household level increases annually from 2007 to 2009. By 2009,the consumption rate of qualified iodized salt in each county is more than 90%, which has reached the national standard stipulated in "the evaluation programs for fulfilling the goal of eliminating IDD at county level".

OBJECTIVETo improve the method for monitoring sleep state and respiratory rhythm of SD rats, providing a solution for rats' chewing on the wires, signal loss and instability problems in the animal model of sleep apnea syndrome (SAS).

METHODSWe improved monitoring electrodes of both electrocorticogram (ECoG) and electromyogram (EMG), signal circuit and animal operation.

RESULTSOperation time was shortened and wound exposure time was reduced, which made it easier for postoperative recovery. The ECoG and EMG signals were more stable with sharp image, and signal circuit lines had better conductivity and material durability, achieving continuous monitoring for a long time and high success rate. We could precisely distinguish the sleep wake state and the sleep apnea events in rats according to these signals.

CONCLUSIONThe improved method is more reliable and practical to test the small animal model of SAS, and is more easily to operate and the signals are more stable.
