One strain of Pseudoalteromonas sp. E18 was isolated from the sea mud of Ningbo, Zhejiang. It can produce indigo pigment. The morphological, cultural and biochemical characteristics of the bacterium were studied. The indigo pigment was also extracted. The results showed that the maximum absorption peak of the pigment was at 579nm. The pigment was stable to UV, Na_2SO_3,It was also stable at pH 3～9. The pigment was unstable to the sunlight and high concentration H_2O_2. Temperature of 60℃～80℃ could increase the hue while temperature higher than 90℃ could reduce the hue.

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

Objective To investigate the prevalence of anti-endothelial cell antibody fAECA) in the sera of patients with connective tissue diseases(CTD)complicated with pulmonary arterial hyperten-sion (PAH)and to detect the specific antigens of AECA which may be related to clinical manifestations.Methods AECA was detected with Western blotting in 39 CTD patients with PAH.22 CTD patients without PAH and 30 healthy donors.Results The prevalence of AECA was 82%in CTD patients with PAH.73%in CTD patients without PAH and 20%in healthy donors.Anti-22 000 AECA was only detected in CTD patients with PAH(15%).Anti-75 000 AECA was more frequently detected in CTD patients with PAH than in thosewithout PAH(51%vs 23%.P＜0.05).In CTD patients complicated with PAH.anti-75 000 AECA was morefrequently detected in those with Raynaud's phenomenon or with positive anti-RNP antibody.Conclusion AECA can be more frequently detected in CTD patients with or without PAH.Furthermore,anti-22 000 and anti-75 000 AECA may play a special role in CTD patients with PAH.

The computer-assisted surgery system is a complex system. All of the errors can be attributed to the loss of correspondence between the world coordinate system in the operation room and the virtual world coordinate system obtained from the multi-model medical images. The system's accuracy is composed of the accuracy of the localizer and that of registration. In order to improve the system accuracy, we analyse most of the possible error sources. The accuracy of the localizer affects deeply the registration between the intra-operation and pre-operation data. The localizer is the most basic and important part for a computer-assisted surgery system. We give a comprehensive possible error source at the end of the paper.

ObjectiveTo explore the reliability and validity of WHO ICF-Clinical Checklist for patients with spinal cord injuries.MethodsClinical testing, case records and check had been implemented for 50 patients with spinal cord injuries with ICF-Clinical Checklist, ADL and ASIA.Results and ConclusionThere were high test-retest reliability and validity in WHO ICF-Checklist for patients with spinal cord injuries.

Hypoxic preconditioning with different simulated altitudes (3?000 m and 5?000 m) was performed on Wistar rats and the evoked population spikes were recorded from the hippocampal slices of these rats. The results showed that the appearance of hypoxic injury potential (HIP) and the disappearance of presynaptic volley (PV) were significantly delayed in response to acute lethal hypoxia. HIP and PV delay became more apparent when the hypoxic preconditioning altitude was increased from 3?000 m to 5?000 m. After reoxygenation, the recovery rate of PV in hypoxic preconditioning groups at 3?000 m and 5?000 m was apparently higher than that of control. The above results suggest that hypoxic preconditioning of animals in vivo increases hypoxic tolerance of hippocampal neurons.

In this paper, three kinds of chemotactic parameters (concentration, temperature and pH) were determined by plate assay and spore germination method to research the chemotactic response of Botrytis cinerea and Alternaria panax, and their spores on total ginsenosides. The results showed that Botrytis cinerea had strong chemotactic response at the mid-concentration of total ginsenosides (cultivation temperature was 20 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.293 0, chemotactic growth rate (CGR) was 0.476 0, spore germination rate (SGR) was 53%, and dry weight of mycelial (DWM) was 0.452 6 g x L(-1); however, Alternaria panax had strong chemotactic response at the low-concentration of total ginsenosides (cultivation temperature was 25 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.235 4, chemotactic growth rate (CGR) was 0.537 0, spore germination rate (SGR) was 67%, and dry weight of mycelial (DWM) was 0.494 8 g x L(-1). The results indicated that the low and middle concentration (2, 20 mg x L(-1)) of total ginsenosides had significant promoting effect on chemotactic response of these two pathogens, and the spore germination, mycelial growth rate, dry weight of mycelial of them were also significantly improved by this chemotactic response, whereas it decreased as the increase of total ginsenosides concentration.

OBJECTIVETo investigate the association between polymorphisms at -14 bp and zinc finger protein(ZNF) sites of ATP-binding cassette transporter A1 (ABCA1) gene promotor and high density lipoprotein-cholesterol (HDL-C) level and coronary heart disease (CHD).

METHODSPolymorphisms of Bme13901 restriction site at -14 bp and an insertion/deletion site of ACCCC in variable number of tandem repeats-zinc finger protein(VNTR-ZNF) of ABCA1 gene were detected using PCR in 260 CHD patients and 220 healthy subjects from a Chinese population in Tianjin.

RESULTSCT genotype was most common in both groups with no differences found in between (P> 0.05). No differences were found in the frequencies of the rare T allele for -14 bp (P> 0.05). For the -14 bp site, subjects with CT/TT genotype had a lower serum mean concentration of HDL-C compared with those with the CC genotype (P< 0.05). Genotypic frequencies of VNTR-ZNF were 6.2% for the inserted form, 43.8% for the deleted form and 50.0% for the inserted/deleted form. No significant difference was found in the distribution of allele and genotype, or in the levels of HDL-C between the two groups (P> 0.05).

CONCLUSIONThe genotypes at -14 bp of ABCA1 gene are associated with the plasma level of HDL-C. HDL-C levels in T allele carriers were significantly lower (P< 0.05). No association was found between variations in ABCA1 VNTR-ZNF and plasma levels of HDL-C, or between the ABCA1 -14 bp and VNTR-ZNF polymorphisms and susceptibility for CHD.
