To improve the yield of industrial fermentation, a method based on near infrared spectroscopy was presented to predict the growth of yeast.The spectral data of fermentation sample were measured by Fourier-transform near-infrared (FT-NIR) spectrometer in the process of yeast culture.Each spectrum was acquired over the range of 10000-4000 cm1.Meanwhile, the optical density (OD) of fermentation sample was determined with photoelectric turbidity method.After that, a method based on competitive adaptive reweighted sampling (CARS) was used to select characteristic wavelength variables of NIR data, and then extreme learning machine (ELM) algorithm was employed to develop the categorization model about the four growth processes of yeast.Experimental result showed that, only 30 characteristic wavelength variables of NIR data were selected by CRAS algorithms, and the prediction accuracies of training set and test set of the CARS-ELM model were 98.68% and 97.37%, respectively.The research showed that the near infrared spectrum analysis technology was feasible to predict the growth process of yeast.

The antagonism of two strains B1 and B2 of Bacillus spp. against pea root rot pathogen Fusarium oxysporum f. sp. pisi was studied. The result of pairing culture showed that B1 and B2 strains of Bacillus spp. had strong antifungal activity to the pathogen. The colonial color of the pathogen changed from gray to white, aerial hyphas increased and entangled into group after treatment with the cell-free fermentational filtrate of B1 or B2. Observation under optical microscope showed that hyphas and spores of the pathogen swelled and distorted with concentrated cytoplasm after treatment, the spores could not germinate or germinated abnormally . A lot of vesicles appeared at the top of the hyphas, and the hyphas stopped growing and broke finally, their cytoplasm spilled from the cell. The cell-free fermentational filtrate of B1 or B2 strains contained 1795.53?g/mL and 1345.93?g/mL protein respectively, from which two antifungal proteins of 103.5 kD (B1 ) and 127.6 kD (B2) were purified.

It is a trend that innovate the traditional bilingual education model and select a new teaching model.Code-switching is a lingual phenomenon when a passages or articles are expressed with two or more language.To guarantee effect of bilingual education and improve education quality,penetration bilingual education was applied during microbiology teaching.Professional English vocabulary,words,passages or articles were introduced to students timely and by measure by the way of language code-switching.The results showed that bilingual teaching mode with language code-switching inspire study emotion and self-confidence of English expression from students.

OBJECTIVETo study the changes of the amplitude-integrated electroencephalography (aEEG) tracings within 6 hours after birth in term infants with hypoxic-ischemic encephalopathy (HIE) and explore the value of aEEG in early diagnosis and prediction of neurological outcome in term infants.

METHODSFrom May 2003 to February 2005, 33 term infants with HIE at the Division of Neonatology, Pediatric Hospital of Fudan University were studied by aEEG within 6 hours after birth. The results of aEEG were categorized into three groups (normal, mildly abnormal and severely abnormal aEEG), while HIE was clinically classified into three grades (mild, moderate and severe) and the neurological outcomes at 18 months were assessed (normal, disabled and dead). The correlation between the results of aEEG, severity of HIE and neurological outcome at 18 months were analyzed, respectively. The values of aEEG on early diagnosis and neurological outcome prediction of HIE were analyzed.

RESULTSAmong the 33 term infants with HIE, 20 infants had normal aEEG (normal amplitude aEEG), 5 had mildly abnormal aEEG (4 with mildly abnormal amplitude aEEG, 1 with normal amplitude and seizure) and 8 had severely abnormal aEEG (2 with mildly abnormal aEEG and seizures, 4 with severely abnormal amplitude and 2 with severely abnormal amplitude and seizures), respectively. Seventeen infants (51.5%) had mild HIE, 19 moderate (27.3%) and 7 (21.2%) severe HIE, respectively. Twenty-five cases were followed up, which showed that 19 had normal neurological outcome, 1 had disability and 5 died. By CMH square analysis and Spearman rank correlation analysis, the results of aEEG classification were correlated with the severity of HIE and the neurological outcome of term infants. Abnormal aEEG could predict the severity of HIE in term infants with a sensitivity of 100%, specificity of 81.3%, positive predictive value of 85.0% and negative predictive value of 100%, respectively. Abnormal aEEG could predict the neurological outcome of term infants with HIE, which showed a sensitivity of 100%, specificity of 90.9%, positive predictive value of 93.3% and negative predictive value of 100%, respectively. Severely abnormal aEEG could predict the severe HIE in term infants with sensitivity of 96.2%, specificity of 100%, positive predictive value of 100% and negative predictive value of 87.5%, respectively. Severely abnormal aEEG could predict the neurological outcome of term infants with HIE, which showed sensitivity of 94.7%, specificity of 100%, positive predictive value of 100% and negative predictive value of 85.7%, respectively.

CONCLUSIONSMonitoring with aEEG in term infants with HIE within 6 hours after birth could predict the severity of HIE and its neurological outcome at 18 months.

ObjectiveTo observe the influence of iodine on mRNA expression of iodide transporter (NIS),insulin-like growth factor Ⅰ (IGF- Ⅰ ) and transforming growth factor beta(TGF-β) in thyroid and mammary glands of lactating rats and to explore the role of NIS,IGF- Ⅰ and TGF-β mRNA in iodine uptake in thyroid and mammary glands of lactating rats.MethodsOne hundred and one Wistar rats(80 female and 21 male),weighting 8 - 100 g were selected.These female rats were randomly divided into five groups according to their body weight:control group(NI,normal feed,drank deionized water containing iodine 50 μg/L) ; low iodine group 1 and 2(LI-1,LI-2,low iodine feed,drank deionized water containing iodine 0 and 5 μg/L,respectively); high iodine group 1 and 2(HI-1,HI-2,normal feed,drank deionized water containing iodine 3000 and 10 000 μg/L,respectively),16 rats in each group.After feeding for 3 months,the female and male rates were mated 3:1.The female rats in each group were sacrificed at the fifth and tenth day after postpartum.Thyroid and mammary glands were taken.The mRNA levels of NIS,IGF- Ⅰ and TGF-β in thyroid and mammary glands of lactating rats were determined by real time quantitative PCR.ResultsThe fifth days after postartum,NIS,IGF- Ⅰ and TGF-β mRNA expression levels of thyroid and lactating mammary glands were different between groups,and the differences were statistically significant ( NIS:F =631.46,64.91,all P ＜ 0.01 ; IGF- Ⅰ:F =11.45,6.56,all P ＜ 0.01 ; TGF-β:F =291.83,304.53,all P ＜ 0.01).Compared with control group [NIS:0.0066 ± 0.0023, (0.1481 ± 0.0711 ) × 10-2; IGF- Ⅰ:0.0419 ± 0.0062,0.0542 ± 0.0044; TGF-β:0.1416 ± 0.0277,0.1670 ± 0.0499],regardless of thyroid or mammary gland,the NIS,IGF- Ⅰ and TGF-β mRNA expression of LI-1 [NIS:0.0447 ± 0.0110,(0.3030 ± 0.1831) × 10-2;IGF- Ⅰ:0.0662 ± 0.0078,0.0902 ± 0.008; IGF- Ⅰ:0.5514 ± 0.0508,0.6942 ± 0.0367],LI-2[NIS:0.0317 ±0.0081,(0.3017 ± 0.1601) × 10-2; IGF-I:0.0645 ± 0.0054,0.0894 ± 0.0093; TGF-β:0.5292 ± 0.0332,0.6704 ± 0.0277 ] was significantly increased (all P ＜ 0.01 ); the NIS mRNA expression of HI-1 [0.0043 ± 0.0011,(0.1233 ± 0.0954) × 10-2],HI-2[0.0037 ± 0.0017,(0.1058 ± 0.0854) × 10-2] was decreased(all P ＜ 0.05),while the expression of IGF-Ⅰ mRNA [0.0521 ± 0.0910,0.0715 ± 0.0026; 0.0516 ± 0.0078,0.0697 ± 0.0038] and TGF-β mRNA [0.2087 ± 0.0425,0.2361 ± 0.0425; 0.1971 ± 0.0237,0.2257 ± 0.0752 ] was increased (all P ＜ 0.05 ).The tenth days after postpartum,the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of thyroid and lactating mammary gland in rats were different between groups,and the differences were statistically significant (NIS:F =103.55,116.32,all P ＜ 0.01; IGF-Ⅰ:F =67.67,11.98,all P ＜ 0.01; TGF-β:F =74.30,381.30,all P ＜0.01 ).Compared with the control group[NIS:0.0069 ± 0.0011,(0.1337 ± 0.0599) × 10-2; IGF-Ⅰ:0.0390 ±0.0071,0.0534 ± 0.0056; TGF-β:0.1351 ± 0.0336,0.1534 ± 0.0320],the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of LI-1 [ NIS:0.0432 ± 0.0165,(0.2962 ± 0.0985 ) × 10-2; IGF- Ⅰ:0.0643 ± 0.0088,0.0873 ± 0.0055 ; TGF-β:0.5042 ± 0.0912,0.6408 ± 0.0420],LI-2[NIS:0.0287 ± 0.0111,(0.2873 ± 0.0862) × 10-2; IGF- Ⅰ:0.0621 ± 0.0094,0.0862 ± 0.0038; TGF-β:0.4893 ± 0.0504,0.6372 ± 0.0389] were significantly increased(all P ＜ 0.01 ); the NIS mRNA levels of HI-1 [ 0.0042 ± 0.0029,(0.1006 ± 0.0909) × 10-2],HI-2[0.0035 ± 0.0020,(0.0890 ± 0.0119) × 10-2] were decreased(all P＜ 0.05),while the expression of IGF-Ⅰ mRNA[0.0516 ± 0.0078,0.0668 ± 0.0071; 0.0508 ± 0.0089,0.0621 ± 0.0064] and TGF-β mRNA[0.2007 ± 0.0546,0.2175 ± 0.0370;0.1959 ± 0.0393,0.2097 ± 0.0425] were increased(all P ＜ 0.05 ).In thyroid and mammary glands,the comparisons of NIS,IGF,TGF-β mRNA expression of the fifth and tenth day after postartum,between each group were not statistically significant(all P ＜ 0.05).ConclusionsThere are regulatory mechanisms of thyroid and mammary glands of lactating rats in response to low or high iodine conditions.In low iodine,the expressions of NIS,IGF- Ⅰ and TGF-β mRNA in thyroid and mammary glands increase and iodide uptake ability is enhanced to meet the body needs.In high iodine,the expression of NIS mRNA decreases in thyroid and mammary glands.Due to the reduced ability of iodine uptake,iodine intake is reduced,thereby reducing the hazards of high iodine in filial rats.

OBJECTIVETo investigate a novel method for the reconstruction of large vermilion defects.

METHODSBased on the size and shape of the defects, a buccinator myomucosal flap pedicled with the junction of buccinator and orbicularis oris in the oral commisure was designed and rotated to reconstruct the large vermilion defects. The upper bound of the flap is at least 1 cm away from the stensen's duct. The width is about 2.5-3.0 cm, and the length is as far as to arrive the raphe pterygomancibularis. The donate site is directly closed primarily. There is no need for secondary pedicle division.

RESULTSFrom July 2003 to April 2013, 14 cases with large vermilion defects was reconstructed with this method. No flap necrosis occurred with primary healing. 5 cases were followed up with an average follow up period of 1 year (0.5-3 years). The apprearance and function of the reconstructed vermilion were satisfactory without any apparent donor site defect. The patients were satisfied with both the functional and cosmetic results.

CONCLUSIONThe buccinator myomucosal flap is a simple and ideal method for reconstruction of large vermilion defects, especially for the defects closed to the commisure.

Objective To evaluate the effects of aspirin-triggered lipoxin A4 (ATL) on lipopolysaccharide (LPS)-induced acute lung injury in mice.Methods Thirty male SPF BALB/C mice,aged 10-12 weeks,weighing 25-30 g,were randomly assigned into 3 groups (n =10 each):normal saline group (group NS),LPS group and ATL groups.ATL 0.1 ml was injected via the tail vein 1 h after intra-tracheal instillation of 3 mg/kg LPS in LPS group.In ATL group,ATL 0.2 mg/kg was injected via the tail vein 1 h after intra-tracheal instillation of 3 mg/kg LPS.At 24 h after instillation,the mice were sacrificed.Bronchoalveolar lavage fluid was collected for determination of the total cell count,proportion of the polymorphonuclear leukocytes,proportion of the mononuclear leukocytes,and concentrations of the total protein,TNF-αt,IL-6,monocyte chemoattractant protein-1 (MCP-1) and IL-10.Lungs were removed for determination of myeloperoxidase (MPO) activity,phosphorylation of p38 mitogenactivated protein kinase (p38 MAPK),c-Jun N-terminal kinase (JNK),and extracellular signal-regulated kinase 1/2 (ERK1/2) in lung tissues and for microscopic examination.The pathological changes of lungs were scored.Results Compared with NS group,the lung injury scores,total cell counts,proportion of polymorphonuclear leukocytes,and concentrations of TNF-α,IL-6 and MCP-1 were significantly increased,and the proportion of mononuclear leukocytes was decreased in LPS and ATL groups,and IL-10 concentrations were decreased,and the concentrations of the total protein,MPO activity,and phosphorylation of p38 MAPK,JNK and ERK1/2 were significantly increased in group LPS (P ＜ 0.05),and no significant change in the concentrations of the total protein,MPO activity,phosphorylation of p38 MAPK,JNK and ERK1/2 was found in group ATL (P ＞ 0.05).Compared with LPS group,the lung injury scores,total cell counts,proportion of polymorphonuclear leukocytes and the concentrations of the total protein,TNF-α,IL-6 and MCP-1 were significandy decreased,the proportion of mononuclear leukocytes and IL-10 concentration were increased,and MPO activity and phosphorylation of p38 MAPK and JNK were decreased (P ＜ 0.05),and no significant change in the phosphorylation of ERK1/2 was found in group ATL (P ＞ 0.05).Conclusion ATL can ameliorate LPS-induced acute lung injury by inhibiting activations of p38MAPK and JNK signal pathways in mice.

Objective To investigate the influence of motor impersistence on functional recovery and prog- nosis of patients with left hemiplegia. Methods A total of 64 in-patients with left side hemiplegia who were able to understand the oral instructions were assigned into a motor impersistence group (n = 31 ) and a control group (n = 34) , respectively, according to the assessment with Scale of Motor Impersistence developed by Joynt. Both groups were comparable in terms of the basic clinical characteristic and motor function of patients except motor impersis- tence. The conventional rehabilitation training programs were adopted for all patients in this study. Brunnstrom func- tional category, Ueda Satoshi hemiplegic finger function assessment scale, upper limb function assessment scale, Berg balance scale, Functional ambulatory category, Modified Barthel Index were employed to evaluate the subjects before and after 1 and 2 months of treatment, with regard to the motor function of their upper limbs, walking ability, activities of daily living performance and balance ability. Results After 1 month of treatment, the patients in the M1 group were significantly improved with regard to the motor function of upper limbs, hand function, standing ba- lance and activity of daily living performance( P0.05 ) , while those in the control group were improved with all the parameters except the lower limb function. After 2 months of treatment, patients in both groups were all significantly improved ( P
