Objective To investigate the condition of exercise, medicine compliance and the rehabilitation of patients with arteriosclerosis obliterans (ASO) in lower extremity after the surgery, and also to study the influence of self-efficiency and social support to their rehabilitation. Methods The questionnaire survey was performed in 102 patients who had surgical or interventional therapy of arteriosclerosis obliterans in the lower extremity in our hospital, investigated the general information of the patients, their knowledge of postoperative rehabilitation, medicine compliance, exercise condition, general self-efficiency and social support. Results The postoperative time for the patients with arteriosclerosis obliterans was 2 to 22months, the knowledge rate for postoperative rehabilitation was 7.8%-46.1%.The Morisky score for the patients of taking medicine for the treatment of vascular disease was 2.0,and there was only 6 patients(5.9%)with good medicine compliance. There were 22 patients(21.0%) had completed the ambulation training according to the guidelines, and there were 25 patients(24.5%) had completed the Buerger training. The self-efficiency score of the patients was 2.78 ± 0.76, and the gross score of social support was 32.38 ± 7.89. Spearman correlation analysis shows that the Morisky score for the patients of taking medicine for the treatment of vascular disease was in positive correlation with self-efficiency (r=0.289, P=0.003), but in negative correlation with social support (r=–0.286, P=0.006). Conclusions Most of the patients with arteriosclerosis obliterans have poor medicine compliance, and do not do exercise as required by the guidelines. Patients with high self-efficiency demonstrates medicine noncompliance, however the enhancement of social support will help patients improve their medicine compliance.

Natural product seselin and related derivatives with an angular pyranocoumarin skeleton were synthesized from 8-acetyl-7-hydroxycoumarins by condensation with acetone, reduction, and dehydration successively under mild conditions with total yield of > 50%. Twelve seselin derivatives were tested by the writhing response assay induced by acetic acid at a dose of 40 mg x kg(-1). Seselin (4a) and 4,8,8-trimethyl-9,9-dihydro-pyran[2,3-f] chromene-2,10-dione (2b) showed obviously antinociceptive activity with inhibitory effect of 85% and 50%, respectively, more or quite potent than aspirin in the same assay, suggesting that seselin derivatives could be a novel kind of potential antinociceptive agents.

OBJECTIVETo investigate the effect and mechanism of Scutellaria Baicalensis Stem-leaf Total Flavonoid (SSTF) on lipid metabolism in hyperlipidemic rat.

METHODOn the basis of establishing hyperlipidemia rat model, blood lipids, lipid metabolic enzyme, antioxidative capacity were investigated after 30 days feeding of fatty emulsion.

RESULTSSTF significantly reduced the serum TC, TG, LDL-C, ApoB concentration and increased HDL-C and ApoAI levels, improved the activity of lecithin cholesterol acyltransferase (LCAT). SSTF was shown to decreased MDA content in both serum and liver, increased serum SOD activity.

CONCLUSIONSSTF could remarkably modulate the lipid metabolic disorder in hyperlipidemic rats, and has a certain regulating function on lipoprotein, inferring that it could reduce the occuring of atherosclerosis. The mechanism of regulating lipid metabolism might be related with the increasing activity of LCAT and antioxidative capacity.

OBJECTIVETo identify the antithrombin (AT) phenotype and gene mutation of a kindred with hereditary antithrombin deficiency.

METHODSPlasma AT activity and AT antigen level of the propositus and his kindred members were determined with chromogenic substrate method and immunoassay, respectively. All the seven exons and intron-exon boundaries of antithrombin gene were analyzed by PCR and direct sequencing of amplified PCR products from the propositus.

RESULTSThe propositus AT antigen level was normal but his AT activity was only 65% of normal value suggesting that he had type II AT deficiency. A heterozygous G13830A mutation in exon 6 resulting in Arg393His missense mutation in his AT polypeptide was identified in the propositus. The same phenotype and gene mutation were found in other 3 kindred members.

CONCLUSIONThe type II AT deficiency found in this kindred is caused by heterozygous G13830A mutation in AT gene.

Objective To provide updated recommendations for further adjustment of iodine deficiency disorders control strategy by evaluating awareness of the dangers of iodine deficiency disorders and their prevention and control measures among local residents and the willingness of choosing iodized or non-iodized salt in urban communities of Jiangsu province.Methods Trained health service workers did questionnaire investigation on iodine deficiency disorders prevention knowledge by calling computer-randomly selected family telephone numbers in every two blocks of provincial capital (Nanjing) and coastal city (Nantong) in Jiangsu province in 2010.The survey topics covered include:when supplied with both non-iodized and iodized salt,what kind of salt the local residents chose and the reasons; residents awareness of the dangers of iodine deficiency disorders and their prevention and control measures; resident's personal information(including only occupational category and age group).Key fields were rechecked from 10％ randomly selected valid questionnaires.Results Four hundred and fifty-five valid questionnaires were obtained by calling 2021 randomized telephone numbers in Nanjing and Nantong cities.After 10.1％(46/455) of the valid questionnaires were rechecked,the total coincidence rate was 87.0％(40/46).In the two cities,there were 73.2％ (333/455) of those 455 respondents saying they would choose iodized salt when iodized and non-iodized salt were supplied at the same time.There were 69.0％(314/455) of respondents had heard of iodine deficiency disorders,of which 79.6％(250/314) of them were aware of the dangers of iodine deficiency is endemic goiter,and 10.8％ (34/314) of them knew that iodine deficiency can cause varying degrees of mental damage.With respect to useful preventive methods of iodine deficiency disorders,there were 69.4％ (218/314) respondents know that eating iodized salt,and 41.1％ (129/314) respondents know that taking laver or kelp would prevent iodine deficiency disorders.Conclusions Remarkable achievements on iodine deficiency disorders health promotion and health education have been gained in urban communities of both the provincial capital and the coastal city Jiangsu province.However,some of the people are still not very clear why we should eat iodized salt.Salt industry in the current management system,is still premature to provide iodized salt and non-iodized salt simultaneously now.

Objective To assess the integrity and standardization of structured MRI report for rectal cancer of the affiliated hospital of qingdao university,referring to National Comprehensive Cancer Network (NCCN) guidelines for colorectal cancer (Version 2015)and foreign authoritative research results,and put forward some suggestions to improve the quality.Methods A total of 110 structured MRI reports of 107 patients with rectal cancer were included in the study.The inclusion rates of 8 indexes were evaluated,including tumor site,distance from upper to lower border of tumor (DIS),tumor invasive depth (T staging),anal complex staging (A staging),nodal staging (N staging),the circumferential resection margin (CRM),extramural vascular invasion (EMVI) and metastases staging (M staging),which were compared with research results of structured reports in abroad by using Pearson chi-square test.Results There was a significant difference in the description of N staging (x2 =8.424,P＜0.05) between our research and foreign study,in 110 structured MRI reports.There was no significant difference in the description of tumor site (x2 =0.00,P＞0.05),DIS (x2 =0.041,P ＞0.05),T staging (x2 =3.256,P＞0.05) and CRM(x2 =2.957,P＞0.05) between the two groups.A staging,EMVI and M staging were not described.Conclusion Our structured MRI reports for rectal cancer basically meet international research standards.Structured MRI reports have advantages,and deserve to be further studied and promoted.

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

OBJECTIVE To explore the mechanism of Gαiand Gβγsubunits on dexmedetomidine (DMED)-induced sedation.METHODS Kunming mice were randomly placed into three groups(DMED group, DMED+dbcAMP/rolipram/gallein/M119 group, dbcAMP/rolipram/gallein/M119 group) to explore the regulation of dbcAMP/rolipram/gallein/M119 on DMED-induced sedation by establishing loss of righting reflex (LORR) model. DbcAMP/rolipram was intracerebroventricular injected and gallein/M119 was intraperitoneal injected 15 min before DMED intravenous injection. In CHO-α2A-AR cells, after administration of DMED/gallein/M119, the regulation on the cAMP accumulation stimulated by Forskolin (FSK) was detected, so was the intracellular calcium ion concentration ([Ca2+]i. The levels of pERK/pCREB were detected by Western Blot to explore the key signal molecules involved in DMED-induced sedation. RESULTS The ED50of DMED-induced LORR (200.0 nmol·kg-1) was increased to 375.0 or 433.3 nmol·kg-1by pre-treatment with cAMP analog dbcAMP(50 nmol/5μl per mouse)or phosphodies-terase 4 inhibitor rolipram(100 nmol/5μl per mouse).In addition,the ED50of DMED-induced LORR was decreased to 113.6 or 136.5 nmol·kg-1when pre-treated with Gβγsubunits inhibitor M119(100 mg·kg-1) or gallein(100 mg·kg-1)respectively.Administration of dbcAMP,rolipram,gallein or M119 alone had little effect on LORR of mice.Gallein(10 μmol·L-1)significantly inhibited forskolin-stimulated cAMP accumu-lation in CHO-α2A-AR cells.Compared with Gβγsubunits inhibitors or DMED alone,[Ca2+]iand pERK1/2 significantly increased after co-administration of Gβγsubunits inhibitors with DMED.DbcAMP(5 μmol·L-1) or rolipram (5 μmol·L- 1) alone had little effect on ERK1/2 phosphorylation, but decreased DMED-induced ERK1/2 phosphorylation after co-administration with DMED. Gβγsubunit inhibitors treatment increased DMED-induced phosphorylation of CREB, whereas dbcAMP or rolipram had little effect on pCREB induced by DMED.CONCLUSION Gβγsubunits might inhibit DMED-induced sedation through cAMP and pERK1/2 pathway,which was opposite to Gαisubuint.

Objective To affirm and calssify the arsas with high water iodine and the endemic areas of indline excess goiter in Jiangsu Privince accirding to mational standard.Methods A cross section survey was condueted in 2005 at township level in Fenxian,Tongshan,Suining,Pizhou counties in Xuzhou municipal and Chuzhou district in Huai'an municipal in Jiangsu Province One sample of dringing well water from five directions in the five villages located dircetions of every township namely east west south north and central.was tested for its water iodine concentration.If the sample number sas less than 5 in one village,then all the well water would be tested Endemic stutas of iodine excess goiter was investigated in those townships whose menian water iodine comcentration was between 150 to 300 μg/L Then status was affirmed and reclassifed according.to National Criteria GB/T 19280-2003 Results In all 158 tawnships from the 6 counties the median of water iodine concentration in 79 townships were over 150 μg/L with 32 townships in the range of 150 to 300μg/L In those 32 townships 9 met the criteria of area of high water iodine 23 accorded with that of encemic areas of iosine excess goiter 16 had stopped the supply of non-iodzed salt in advace,but 16 newly detected areas were still served with iodized salt Four were 300 μg/L Conctusions Iodized salt intervention should be stopped in all townships with the problems of high water iodine and the endmic areas of iodine excess goter in order to prevent the possible hazards due to double intade.

This study was purposed to analyze the characteristics of morphology, immunology, cytogenetic and molecular biology of leukemia cells in 12 AML patients with Ph(+) and their correlation with survival of patients. 12 patients with Ph(+) AML were diagnosed according to diagnostic criteria of WHO and existence of t(9;22) (q34;q11) or t(9;22) abnormality, meanwhile no evidence of CML chronic phase was observed. The results showed that 8 out of 12 cases were confirmedly diagnosed to be AML by morphologic and immunophenotypic examination, 4 cases were diagnosed as myeloid and B lymphocytic mixed acute leukemia. The Ph chromosome was detected in 10 cases by chromosome analysis at the first time of diagnosis, and some of the cases had coexistence of complex chromosome and/or normal karyotype. BCR-ABL transcript was detected in all 12 cases, including 7 cases with b3a2, 1 case with b2a2, 1 case with b2a2 variants, 2 cases with e1a2 and 1 case with e18a2. The 12 cases all got complete remission after chemotherapy and/or gleevec treatment, out of them 3 cases received chemotherapy and gleevec treatment, but 2 cases died; 9 cases received allogeneic hematopoietic stem-cell transplantation (allo-HSCT), 1 case died from relapse, among them 1 case died from transplant complications. The median survival was 24 (8 - 80) months, the overall survival of 3 years was (51.4 ± 17.7)%. It is concluded that the Ph(+) AML is a acute myelogenous leukemia with poor prognosis, but long-term survival may be achieved with HSCT as quick as after complete remission from gleevec and chemotherapy treatment. Meanwhile, the detection of BCR-ABL gene and it variants may be give more opportunity for diagnose and treatment, which can be used as routine screening for newly diagnosed leukemia.
