Objective To study the correlation between human leukocyte antigen (HLA)-DRB1 alleles and anti neutrophil cytoplasmatic antibodies (ANCA) in Han and Uygur ulcerative colitis (UC)patients in Xinjiang region.Methods The serum ANCA was determined by indirect immunofluorescence assay in 62 Uygur UC patients,58 Han UC patients,188 Uygur and 184 Han healthy control individuals.HLA-DRB1 typing was performed by polymerase chain reaction-sequence based typing (PCR-SBT).The allele frequency of HLA-DRB1 was compared in ANCA positive and negative Han and Uygur patients as well as healthy controls.Stratified analysis was performed according to UC clinical type,severity and involvement.SPSS 17.0 software was applied for x2 test.Once P＜0.05,the odds ratio (OR) and 95％ confidence intervals (95％CI) was calculated.Results The positive rate of ANCA in Uygur UC patients (53.2％,33/62) was significantly higher than that of Han patients (34.5％,20/58) and the difference was statistically significant (x2=4.269,P =0.045).In Uygur,the gene frequency of HLA-DRB1 * 13 in ANCA positive UC patients (0.202)was significantly higher than that of ANCA negative patients (0.017) (x2 =10.092,P=0.016,OR=16.000,95％CI:2.892 to 88.524) and healthy controls (0.075) (x2=9.351,P＝0.040,OR=3.407,95％CI:1.666 to 6.971).The gene frequency of HLA-DRB1 * 13 in ANCA positive pancolitis type UC patients (9/15) was significantly higher than that of ANCA negative pancolitis type UC patients (1/14) and the difference was statistically significant (x2=8.955,P =0.040,OR =19.500,95％CI:2.787 to 136.461).However,in Han patients,there were no significant differences of HLA-DRB1 alleles frequencies among ANCA positive patients,ANCA negative patients and healthy controls (all P＞0.05),and the results of stratified analysis were same.Conclusions In Uygur UC patients of Xinjiang region,HLA-DRB1 * 13 may correlated with ANCA and with ANCA of pancolitis type UC patients.There is no such correlation in Han patients of Xinjiang region.

Objective To investigate the knowledge level and needs in Xinjiang Uygur and Han patients with ulcerative colitis (UC), compare the differences between the two ethnic groups. Methods A total of 194 Uygur and Han UC patients were investigated with the general information questionnaire, the Crohn′s and Colitis Knowledge Score (CCKNOW) questionnaire, disease related knowledge needs questionnaire, to analyze the investigate results. Results CCKNOW score of Uygur and Han UC were (6.9±3.5) points and (9.2±3.1) points respectively, and Uygur was significantly lower than that of Han (Z=-2.831, P=0.005). Knowledge accuracy of dietary (30% and 63%) and drug (45% and 44%) were higher than general information (24% and 32%) and complications (12% and 30%) . Disease related knowledge needs score of Uygur and Han UC patients were (168.2±15.6) points and (155.4±17.2) points respectively, the score of Uygur patients was significantly higher than that of Han patients (t=4.429, P=0.001).The highest disease related knowledge needs score was (4.7±1.0) points of reproductive knowledge for Uygur UC patients, for Han patients was knowledge of daily life which was (4.8 ± 0.8) points. Conclusions The disease related knowledge level of Xinjiang Uygur and Han UC patients are relatively low, especially lack of general knowledge and diet knowledge, disease related knowledge of Uygur UC patients are lower than Han patients. The needs of the disease knowledge are very high for two ethnic groups, different one has different ethnic, gender, age, education level, living environment, hospitalization times, areas of disease related knowledge needs are also different. It is necessary to choose the targeted education content and suitable education way according to individual differences for nursing staff.

Objective To investigate the conrelation between neutrophils lymphocytes ratio (NLR) and disease activity of ulcerative colitis (UC).Methods Case-control study was used to compare NLR differences of 82 active UC patients,45 inactive UC patients,and 254 healthy controls.The multivariate analysis was applied to analyze the correlation between the NLR,erythrocyte sedimentation rate (ESR),Creactive protein (CRP),white blood cells (WBCs),and UC activity.The sensitivity and specificity of NLR to identify UC activity was evaluated.Results NLR of active UC group was 2.45 ± 1.22,which was significantly higher than that of inactive UC group and healthy control group,their NLR were 1.92 ± 0.68 and 1.83 ±0.75,respectively (H =9.991,P =0.007).The multivariate analysis showed that only CRP was correlated with UC activity (OR =1.396,95％ CI:1.086 ～ 1.795,P =0.009).Receiver operating characteristic (ROC) curve analysis showed that the optimum NLR cut-off point for UC activity was 2.23,the sensitivity and specificity were 55.82％ and 62.75％,respectively.Conclusions NLR has a certain reference value for the evaluation of UC activity,but it cannot be independent as a clinical index to evaluate the UC activity.

BACKGROUND:Interleukin-12 (IL-12) may function as an immune regulator in the pathogenesis of osteoarticular tuberculosis. OBJECTIVE:To explore the association of single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C with susceptibility to osteoarticular tuberculosis and serum interleukin-12 levels in Guangxi Zhuang population. METHODS:The single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C polymorphisms were detected by polymerase chain reaction-single base extension technique and direct DNA sequencing in 150 patients with osteoarticular tuberculosis (disease group) and 165 healthy individuals (control group) in Guangxi Zhuang population. The genotype and al ele frequencies of IL-12 and the relationship of genotypes to the susceptibility to osteoarticular tuberculosis were analyzed. In addition, the association of genotypes of single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C with serum IL-12 levels were analyzed. RESULTS AND CONCLUSION:There was no significant difference in the genotype and al ele frequencies of IL-12A rs568408 G/A and IL-12B rs3212227 A/C between the disease group and the control group (P>0.05). Moreover, there was no difference in four haplotypes of IL-12 gene between the disease group and the control group (P>0.05). Serum IL-12 levels in subjects with osteoarticular tuberculosis carrying the variant rs568408 GA/AA genotypes and wild-type rs568408 GG genotypes were similar (P>0.05). Similarly, there was no significant difference in serum IL-12 levels between subjects with osteoarticular tuberculosis carrying the variant rs3212227 AC/CC genotypes and wild-type rs3212227 AA genotypes (P>0.05). These findings suggest that the single-nucleotide polymorphisms in IL-12A rs568408 G/A and IL-12B rs3212227 A/C polymorphisms are not associated with susceptibility to osteoarticular tuberculosis in Guangxi Zhuang population.

Natural product is an important source of new drug research and development (R&D). Traditional Chinese medicine (TCM) innovation is the key step for its modernization and internationalization. However, due to the complexity of TCM, there are many difficulties and confusions in this process. Target-based drug discovery is the mainstream model and method of R&D. TTD, short for therapeutic target database, is developed by National University of Singapore. Besides a large amount of information on drug targets, the database also contains considerable information related to natural products. This paper briefly introduces the TTD, analyzes the natural products derived drugs/compounds recorded in TTD, which we think might provide some inspiration for the innovation of TCM.

Objective To analyze the clinical characteristics of new onset diffuse type ulcerative colitis.Methods From May 2007 to March 2012,clinical data of hospitalized patients diagnosed in the People's Hospital of Xinjiang Autonomous Region as new onset ulcerative colitis were retrospectively analyzed,and constituent ratios of nationality,gender,age at diagnosis,residential environment,severity of disease,clinical symptoms,results of laboratory examination,results of colonoscopic examination and results of histopathological examination were compared among the diffuse type,the type of proctosigmoiditis and the type of left-sided colitis.Normal distribution data were analyzed by one-way analysis of variance,skew distribution data and ordinal data were analyzed by Kruskal-Wallis H test,and count data were analyzed by chi-square test in the comparison among the three groups.Results A total of 67 patients with new-onset diffuse type ulcerative colitis were enrolled.The constituent ratios of Han nationality,Uygur nationality and Kazak nationality were 32.8％(22/67),58.2％(39/67),and 9.0％(6/67),respectively.The ratio of male to female was 1.48∶ 1.The age at diagnosis was (43.27 ± 16.91) years old.The ratio of city to countryside was 3.19∶ 1.To the severity of the disease,mild was more common,the proportion of mild,moderate and severe were 56.7％(38/67),20.9％(14/67) and 22.4％ (15/67),respectively.Abdominal pain,diarrhea and purulent stools were the predominant symptoms.Some patients might have fever and tenesmus,a few patients accompanied with abdominal distension,nausea,vomiting and peripheral arthritis.The percentage of increasesed erythrocyte sedimentation rate,hypersensitive Creation protein and plasmatic fibrinogen was 37.3％(25/67),44.8％(30/67) and 31.3％ (21/67),respectively.To compare with patients with proctosigmoiditis and left-sided colitis,the patients with new-onset diffuse type colitis had higher Mayo score and were more prone to develop abdominal pain,diarrhea,severe colitis,and were more common in Uygur nationality.There were statistical differences in abdominal pain,diarrhea,severity,ratio of Uygur nationality and Mayo score in pairwise comparison among the three groups (all P＜0.017).Conclusion Abdominal pain,diarrhea and Uygur nationality are more common in new onset diffuse ulcerative colitis in Xinjiang Region,with relatively high Mayo score and mild to moderate degree,while severity significantly increased compared to the type of proctosigmoiditis and the type of left-sided colitis.

BACKGROUND: There are currently many cryopreservation methods for the aminotic membrane, which have varying effects on the ultrastructure and biological activity of amniotic membrane, but on no one is effective.
OBJECTIVE: To compare the effects of different cryopreservation methods on the ultrastructure and viability of aminotic membrane and to seek the ideal cryopreservation method.
METHODS: Aminotic membrane separated from the fresh placenta was preserved respectively with deep-frozen cryopreservation and vitrification, and everyway was run for 3 and 6 months. Fresh aminotic membrane was used as control. The ultrastructure of aminotic membrane was observed by transmission electron microscopy, and the viability of aminotic membrane was assessed by microcomputer analysis system for biological oxygen consumption, and immunohistochemical staining combined with image analysis system was used for lactate dehydrogenase activity.
RESULTS AND CONCLUSION:After 3 and 6 months of crypreservation, the damage to the ultrastructure of aminotic membrane by vitreous cryopreservation was slighter than that of amniotic membrane cryopreserved at-80℃. Compared with the fresh aminotic membrane, the gray value of lactate dehydrogenase and partial pressure of oxygen were significantly decreased in the cryopreserved aminotic membrane by deep-frozen cryopreservation at 3 and 6 months (P < 0.05) and by vitreous cryopreservation at 6 months (P < 0.05), but there was no statisticaly significant difference in the change rate of oxygen partial pressure and the gray value of lactate dehydrogenase between the fresh aminotic membrane and the cryopreserved aminotic membrane by vitreous cryopreservation at 3 months. The present study led to the conclusion that vitreous cryopreservation protocol alows to not only maintain the integrity of AM, but also to preserve the viability of the cels. So the vitreous cryopreservation is superior to the deep-frozen cryopreservation for cryopreservation of aminotic membrane.

Objective To investigate clinical characteristics and related factors of ulcerative colitis (UC).Methods One hundred and thirty-seven newly diagnosed patients with UC from 2006 to 2009 in the People's Hospital of Xinjiang Uygur Autonomous Region were selected as our subjects.The clinical data were recorded and the patients were followed up for 3 years.Results Of 137 patients,complete remission rate was 38.69％ (53/137),and partial response rate was 61.31％ (84/137).The overall effective rate was 100％ (137/137).The 1-year cumulative relapse rate was 26.28％ (36/137),and 2-year cumulative relapse rate was 49.64％ (68/137),59.85％ (82/137) for 3-year cumulative relapse rate.The occasion rate (≤ 1 time/year)was 27.01％ (37/137),and frequency (≥2 times/year) was 32.85％ (45/137).Fifty-five patients (40.15％ (55/137)) were no recurrence within 3 years.Relapse rate were not relate to gender (P ＞0.05).The relapse rate of patients less than 50 years was 68.09％ (64/94) substantially higher than that over 50 age group (41.86％ (18/43),x2 =8.444,P ＜ 0.05).The relapse rate of Uygur patients (70.42％,50/71) was substantially higher than the Han (48.48 ％ (32/66),x2 =6.851,P ＜ 0.05).The relapse rate of left colon and extensive colon were 71.64％ (48/67) and 71.88％ (23/32),higher than that of rectum(28.94％,11/38) (P＜ 0.05).The relapse rate of severe group (82.61％,19/23) was higher than that of the mild (52.38％,33/63)and moderate groups (58.82％,30/51) (P ＜ 0.05).In maintenance of mitigation group,52.73％ patients (29/55) were received maintenance treatment and relapse of those patients were significantly higher than recurrence group (31.71％,26/82,P ＜ 0.05).Mental stress may be the top one risk factor,which lead to recurrence of UC (64.63％,53/82),followed by imbalance diet (56.10％,46/82) and overwork (39.02％,32/82).Conclusion Relapse rate of the Uygnr UC patients was higher than that of the Han,and young adults has the higher recurrence rates than the elder.The factors of lesion extent,severity,ability to maintain treatment are related to recurrence of UC.Stress,imbalance diet and overwork are risk factors of recurrence of UC.

OBJECTIVE:To provide reference for further promoting the clinical application of chronopharmacology and rational drug use.METHODS:The self-designed questionnairea was used to conduct on-site investigation among participants from 40 hospitals in Anhui province by dint of a meeting.The survey data were analyzed statistically.RESULTS:Totally 170 questionnaires were distributed,and 166 were retrieved,the total response rate was 97.65％.93.37％ of the interviewed pharmacists were aware of the circadian rhythms,and 87.35％ were aware of the circadian rhythms of more than two kinds;interviewed pharmacists expressed better awareness of indicators like gastric acid secretion (75.30％),blood pressure (67.47％) and growth hormone (66.87％) etc.while their awareness of other diseases like anaphylactic rhinitis (66.87％),gastric ulcer (50.60％) and migraine (50.00％) remained to improve.All the interviewed pharmacists recognized the better therapeutic efficacy (84.34％) and lower side effect (81.33％) of chronopharmacology-referred medication;chronopharmacology characteristics of glucocorticoid drugs were best known (34.34％),followed by antihypertensive drugs (25.30％).CONCLUSIONS:Pharmacists in Anhui province have certain knowledge of chronopharmacology such as biological rhythms,biological process or indicators,biological rhythms of disease and advantage of chronopharmacology-referred medication.It indicates that there has been a foundation for popularizing the concept of chronopharmacology in clinical medication in China;but not often contacted physiological processes or indexes,the understanding of biological rhythm of uncommon diseases are still insufficient,and the understanding of chronopharmacology characteristics of various drugs are far from ideal.

Objective: To study influencing factors on the detection rate of colorectal polyps by repeated examination in colonoscopy. Methods: A total of 900 patients in the digestive endoscopy center of the People′s Hospital of Xinjiang Uygur Autonomous Region received colonoscopy, 300 patients were randomly selected for a second examination and they were selected for three times examination from August 2016 to March 2017. Objective factors for colonoscopy were strictly controlled during the examination, such as endoscopists′ experience, endoscopic operating method, cleansing degree of the intestine and withdrawal time. The characteristics of polyps were recorded, including number, location, shape, size and pathological types of polyps. The characteristics of polyps were compared between the same patient, and between the first-examination group, the second-examination group and the third-examination group. Logistic regression was used to analyze the independent influencing factors of missed diagnosis. Results: A relatively high rate of missed diagnosis could occur in multiple polyps, ascending colon polyps, transverse colon polyps, sigmoid polyps, stepless polyps and small polyps (<5 mm) (All P<0.05), and the pathological type was irrelevant to missed diagnosis (P>0.05). Logistic regression analysis showed that the number, location, shape and size of colorectal polyps were all independent factors influencing the detection rate(all P<0.05). The detection rate of polyps in the two times colonoscopy group was higher than that of the one time colonoscopy group, but there was no statistical difference between the second observation and the third observation (P>0.05). Conclusion The number, location, shape and size of colorectal polyps are all independent factors influencing the detection rate. The detection rate of polyps may be improved by using the second colonoscopy.
