The Monascus mutant with high yield of yellow pigment was obtained by using conventional relevant mutation techniques, e.g., treating with physical mutagens(such as UV light) and chemical sub- stances (such as N-methyl-N'-nitro-N-nitrosoguanidine). The yellow pigment was scanned from 300 nm to 600 nm with UV spectrometer, the maximal absorption was determined at 410 nm. The growth characteristic of Monascus mutant is stable, the yellow pigment value and colour hue in liquid fermentation can reach 100 U/mL and 3.5 respectively. The yellow pigment is stable from pH 3 to pH 8, but the precipitation appeared as the pH of the pigment solution lower than 3.

Objective To investigate the relationship among health literacy and treatment compliance and prognosis in patients with diabetes combined tuberculosis.Methods One hundred and eighty-one cases patients with diabetes combined tuberculosis were selected as the objectives and evaluated literacy level,compliance scale by the health literacy scale and compliance questionnaires.The control of tuberculosis,blood glucose control,treatment compliance and prognosis were analyzed in the patients with different health literacy level.Results Of 181 patients,there were 89 cases patients'(basic health literacy group) the total scores of health literacy and compliance were＞80 points,the efficacy of pulmonary tuberculosis control and blood sugar control were respectively 84.2％ (75/89) and 93.2％ (83/89);92 cases patients' the total scores of health literacy and compliance were ≤ 80 points,the efficacy of pulmonary tuberculosis control and blood sugar control were respectively 59.7％ (55/92) and 67.4％ (62/92),the differences were significant (x2 =12.78,18.11;P ＜0.05).Pearson correlation analysis showed that the total scores of health literacy were positive correlated with the scores of treatment compliance (r =0.688,P ＜ 0.001).Logistic regression analysis showed that three dimension of health literacy (health knowledge and concept,healthy lifestyle and behavior,health skills) that can combined predict the variance of rehabilitation compliance(P＜0.01).Conclusion The health literacy level of diabetes combined tuberculosis patients can effectively predict the rehabilitation compliance.Measures should be taken to improve the patient's level of health literacy,so as improve the compliance of rehabilitation and prognosis.

ObjectiveTo evaluate the enteral nutritional schemes for patients with acute cerebral infarction in effectiveness and economy. Methods117 acute cerebral infarction patients with dysphagia were divided into 3 groups. Homogenized diet, sequential intestinal nutrition and intestinal integral protein were provided respectively for these groups by nasogastric tube feeding. The clinical effectiveness was evaluated and the cost-effectiveness analysis was done pharmacoeconomically 14 d later. ResultsThe effective rates of these schemes were 42.5%, 75% and 49%, while the cost-effectiveness ratios were 9.84, 29.37, 42.16 respectively. ConclusionFor the acute cerebral infarction patients with dysphagia, the scheme of sequential intestinal nutrition is most effective, and the homogenize diet is most economical.

OBJECTIVESTo study the phenomena of hepatitis B virus (HBV) integration into the tissues of hilar cholangiocarcinoma (HCCA) and to identify the integration sites in the host genome.

METHODSTen fresh HCCA samples were collected from the tissues by surgical ablation, 1 normal hilar bile duct sample selected as control. Cellular DNA were extracted by Wizard SV Genomic DNA Purification System. PCR-derived assay (HBV-Alu-PCR) was employed to amplify the viral-host junctions which contain the HBV sequence and the adjacent cellular flanking sequences. The PCR products were purified and subjected to sequencing by ABI-3730XL Auto DNA Analyzer. The sequence analysis of viral-host junctions was performed by DNASIS MAX 3.0 bioinformatics software. The insertion sites between viral and cellular sequences were identified through homology comparison using NCBI BLAST and MapViewer search.

RESULTSIn 10 HCCA samples, 5 were demonstrated to have HBV integration fragments with total 6 inserted sites identified. Sequence analysis from viral-host junction showed that HBV X gene inserted into host genome at random distribution with truncated fragments. HBV integration recurrently targeted the unknown region in upstream of CXXC finger protein-1 (CpG-binding protein) gene (4 cases). p53 tumor suppressor gene was also found at the integration site.

CONCLUSIONSThere is high integration rate of HBV DNA into cellular genome of HCCA. HBV integration is found frequently into or close to cancer-related genes. The findings demonstrate that HBV infection might have association with the pathogenesis of HCCA.

OBJECTIVETo investigate the effect of infrasonic field of minesweeper on psychology of minesweeper crews.

METHODSAn experimental ship was selected to conduct infrasonic minesweeping, a control ship of the same type was selected to operate likewise with the infrasound generator turned off, and another group of coast-servicemen was chosen as blank control. Attention-span test, digit memory test, two-digital numbers list and profile of mood states (POMS) were used to test the ship crews and coast-servicemen.

RESULTSThere were no significant differences in psychological parameters between the two ship crews before the experiment. But the scores of two-digit figures list in ship crews were significant lower than that in coast-servicemen, (31.2 +/- 11.8, 36.4 +/- 14.5 respectively vs 45.8 +/- 13.9, P < 0.05). POMS showed that the scores of anger-hostility, fatigue-inertia, and confusion-bewilderment in both ship crew groups [(15.5 +/- 6.4, 18.3 +/- 6.8), (12.1 +/- 5.0,12.3 +/- 4.9), (11.6 +/- 4.4, 12.5 +/- 4.8), respectively] were higher than those in coast-servicemen (13.9 +/- 7.0, 7.6 +/- 4.1, 8.2 +/- 4.3, respectively, P < 0.05 or 0.01), while vigor-activity in experimental group (15.0 +/- 5.9) was lower than that in coast-servicemen (19.7 +/- 4.7). After the experiment, the scores of experimental crews in digit memory test (14.5 +/- 5.0), vigor-activity (12.2 +/- 5.8), fatigue-inertia (15.8 +/- 6.2) were significantly different from those of control crews (17.3 +/- 4.8, 16.5 +/- 4.6, 11.3 +/- 5.1).

CONCLUSIONSThe infrasonic field from minesweeper may injure the crew's psychological health and some neurobehavioral function.

Objective: The current study was designed to observe the clinical results of late course accelerated hyperfractionation(LCAH) radiotherapy in Stage I- II nasopharyngeal carcinoma(NPC) patients. Methods: A total of 108 patients with Stage I- II NPC were divided at random into two groups: conventional fractionation(CF) and LCAH, The patients in CF group received a fraction of 2 Gy daily, 5 days per week, to total dose of 70 Gy/7weeks. The patients in LCAH group were treated with the same fractionation as CF group to dose of 36- 40 Gy, and followed by late course accelerated hyperfractionation radiotherapy: 1.5 Gy, twice daily, with the interval of 6 hours between fractions, to total dose of 69 Gy/6weeks. Results: The complete response rate in the nasopharynx was 89.47％ in the LCAHR and 70.97％ in the CFR at the end of the course (P=0.05). Disappeared rate of cervical lesion was not significant different between two groups (P >0.05). The survival rates of 1, 2, and 3-year were 98.13％ ,93.95％ ,90.87％ in the LCAH and 96.12％ ,80.97％ ,78.55％ in the CF, respectively (P=0.06). There was no significant difference in radiation reaction and sequela between two groups( P >0.05) . Conclusion: The clinical results of LCAH radiotherapy in Stage I- II NPC may be better than conventional fractionation radiotherapy, is worth further study.
