The strain of DG7 isolated from the oilwater sample in DAGANG oilfield could produce surfactant ?acids and gas in the culture medium in which the diesel was sole carbon source .The strain was Gram-negative, motive, rod and growed facultatively in the 0 to 18.5% NaCl. Based on its characters, the strain was identified as a member of the genus Aeromonas, but there were some differences between this strain and the described species of this genus in some biochemical features, suggesting that it could be a new species of the genus.

Objective To investigate the correlation between the plasma unconjugated bilirubin(UCB)and electrical activity of brain in term neonates with hyperbilirubinemia,and explore the parameters that possess the prognostic value and deduce a series of discriminant for prognostic judgment.Methods Thirty-two neonates with hyperbilirubinemia and 31 neonates without hyperbilirubinema(control group)were studied with standard EEG,and they were assessed for their neurological development in 3 and 6 months.A statistical method of Bayes Discriminant analysis was adopted to set up an equation with values of parameters of EEG,clinic datum and consequence.Stepdic and Dis-grim processes were used to pick out the parameters which had great significance for predicting the outcome of nervous system development.A series of discriminant was deduced for prognostic judgment and then cross validation was performed to assess the accuracy of the discriminant.Results 1.The standard EEG and brain electrical activity map records indicated that the hyperbilirubinemia group had longer maximum duration of interburst interval(IBI),longer mean duration of IBI,lower amplitude under all conditions,more anterior dysrhythmia(AD)in wake,and higher incidence of sleep-wake cycle disturbance.2.The plasma concentration of UCB was linear correlated with AD in wake.3.Gestational age,birth weight,plasma concentration of UCB,burst duration of IBI in trace alternate,amplitude in all sleep state,AD in wake,brief burst not in quiet sleep and sleep-wake cycle disturbance might play important roles in predicting the outcome of neonates with hyperbilirubinemia.Conclusions Cerebral electrical activity is an effective tool for predicting neurologic outcome of neonates with hyperbi-lirubinemia.Cerebral electrical activity and clinic data will provide a new method for accurately predicting neurological development and prognosis.

OBJECTIVETo study the origin pre-treating and processing integration techniques of Paeonia Radix Alba.

METHODDifferent processing integration techniques were adopted and compared with traditional processing techniques to determine drying rate, aqueous extracts and peoniflori content.

RESULTHalf-dry slices baked at 100 degrees C for 20 min and steamed at 100 degrees C for 10 min had the highest peoniflori contents. Half-dry slices baked at 100 degrees C for 20 min had the highest content of aqueous extracts. Products processed with conventional method and sulfur-fumigation had the lowest content of aqueous extracts.

CONCLUSIONThe origin processing integration techniques of Paeonia Radix Alba lose less active ingredients than conventional processing methods.

Acyl carrier protein is an essential component involved in the biosynthesis of DHA(Docosahexaenoic Acid) via PKS(Polyketide synthase) pathway,which takes the growing acyl chain from one enzyme to another.One cDNA clone,with high homology of ACP,was isolated from Schizochytrium sp.FJU-512 cDNA library.The deduced amino acid sequence contained 142 residues with isoelectric point of 5.04 and had the 4'-phosphopantetheine prosthetic(4'-PP) binding site.The target fragment was digested with BamHⅠ/HindⅢand inserted into the expression vector pET-30a resulting in the plasmid pET-30a/acp.The recombinant vector was transformed into E.coli BL21(DE3) and induced by IPTG.SDS-PAGE analysis demonstrated that ACP was effectively expressed.

The deep fermentation technique of Tricholoma matsutake is systemically studied in this paper firstly. The best culture determined by orthogonal test is 3g/L of cornflour, 1g/L of glucose, 1g/L of bean cake flour, 1mL/L of corn steep liquid, 1g/L of KH 2PO 4. The best fermenting condition is: 25℃, rotating speed 160 r/min, pH5.0,inoculating amount 10%, 120mL culture medium per 500mL flask. Under these conditions, the mycelia reach 12.94g/L after fermenting 12d.

Objective To investigate surgical opportunity and suitable treatment approach in nodular Hashimoto's disease.Methods An analysis was performed in 388 pathologically confirmed cases with nodular Hashimoto's disease and other thyroid-related diseases.All the cases were involved with surgical treatment due to thyroid nodules from June,1995 to Dec,2005.Results Among the above-mentioned cases,64 cases (16.5%) were Hashimoto's disease with the presence of thyroid cancer,190 (48.9%) nodular thyroid tumor,94 (24.2%) thyroid adenoma,7 (1.8%) hyperthyroidism,the rest (8.5%) simple Hashimoto's disease.Prior to 2000, among 106 cases of Hashimoto's disease there were 15 cases accompanied by thyroid cancer.Since 2001,282 cases of Hashimoto's disease were dealt surgically,49 of which had thyroid cancer.Compared to the period from 1995 to 2000,the complication of Hashimoto's disease and thyroid cancer has been sharply increasing during the recent five years (P

Objective To explore the relationship between 5, 10-methylenetrahydrofolate reeducates gene polymorphism of the parents and the susceptibility to their offspring having neural tube defects. To forecast and evaluate the onset risk of neural tube defects (NTDs) on the basis of 5, 10-methylenetrahydrofolate reeducates (MTHFR) C677T polymorphism on parents of the patients.Methods Electronic search strategy was carried out among the five databases from home and abroad to collect qualified research papers, according to the inclusion and exclusion criteria. Case-control studies on association between MTHFR polymorphism and susceptibility to NTDs were collected and divided into two groups as mothers and fathers. The combined OR values and their 95% CI were calculated with Review Manager 5.0. Results 33 eligible studies were included. Statistics of the combined data showed a significant difference between the mothers with NTDs offspring carrying TT/CC, CT/CC of MTHFR gene C677T and controls. The pooled OR (95%CI) were 1.68 (1.32-2.14)and 1.20 (1.07-1.35) respectively. These was a significant difference between the fathers of the offspring with NTDs that carrying of TT/CC, CT/CC of MTHFR gene C677T and controls. The pooled ORs (95%CI) were 1.38 (1.08-1.76) and 1.32 (1.13-1.55) respectively. Conclusion The results suggested that the paternal and maternal MTHFR gene C677T polymorphism were risk factors to NTDs.
