Objective To analyze mutations in the ATP2A2 gene in a Kazakh family with Darier's disease.Methods Clinical data were collected from 49 members from a family with Darier's disease,and peripheral blood samples were obtained from 44 family members and 100 unrelated healthy people.Genomic DNA was extracted from these blood samples.PCR and DNA sequencing were performed to detect mutations in the ATP2A2 gene.Results Darier's disease was inherited in an autosomal dominant manner in this family.A G→A heterozygous mutation (1288-1G→A) was identified at position 1288-1 at the splice site in exon 12 of the ATP2A2 gene in 11 patients in this family,but not in 33 healthy members or 100 healthy controls.Conclusion Darier's disease in this family may be caused by the heterozygous mutation (1288-1G→A)at the splice site in exon 12 of the ATP2A2 gene.

Objective To investigate the relationship between SFRP1 gene and clinicopathologic features of cutaneous squamous cell carcinoma (CSCC), and to explore the possible mechanism of action of SFRP1 in the occurrence and development of CSCC.Methods CSCC and paracarcinomatous tissue specimens were obtained from 40 patients with CSCC, and normal skin tissue specimens from 40 healthy human controls.The EpiTYPER assay was conducted to evaluate the methylation status of SFRP1 gene promoter in all the specimens with a MassARRAY mass spectrometer.Results Totally, the methylation status of 1951 (86.52％, 1951/2255) CpG motifs were evaluated in 17 CpG loci in 2 fragments of the SFRP1 gene promoter.The methylation rate significantly differed in 10 (10/17, 58.82％) CpG loci between the CSCC and paracarcinomatous tissue specimens, and in 5 (5/17, 29.41％) CpG loci between the paracarcinomatous and normal tissue specimens (all P ＜ 0.05).Furthermore, significant differences were observed in the methylation rates of three CpG loci (CpG 1_5, CpG 1_7, CpG 2_8) in the SFRP1 gene promoter between tissue specimens from different pathological grades of CSCC (P ＜ 0.05), and their methylation rates sequentially decreased from grade Ⅲ to grade Ⅱ and Ⅰ.Conclusion The frequency of methylation is high in the SFRP1 gene promoter in patients with CSCC, and the SFRP1 gene may participate in the occurrence and development of CSCC.

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.

Objective To determine the normal range of minimal erythema dose (MED) for ultraviolet A (UVA) and B (UVB) in volunteers from Urumqi region.Methods One hundred and twenty-seven volunteers including healthy subjects and patients with noninflammatory skin disorders were enrolled in this study.SUV-1000 type UV simulator was used as the light source to determine MED of UVA and UVB in these subjects.Results These subjects included 48 persons with Fitzpatrick skin type Ⅲ,79 with Fitzpatrick skin type Ⅳ,51 males and 76 females.The median MED value for UVA and UVB was 38.1 J/cm2 and 31.8 mJ/cm2 respectively in subjects with skin type Ⅲ,59.16 J/cm2 and 48.00 mJ/cm2 respectively in subjects with skin type Ⅳ.Significantly lower median MED values of UVA (both P ＜ 0.01) and UVB (both P ＜ 0.05) were observed in the male and female subjects with skin type Ⅲ compared with those with skin type Ⅳ.The male subjects showed a significantly higher median UVA-MED value (59.16 J/cm2 vs.41.10 J/cm2,P ＜ 0.05),but a similar UVB-MED value (39.60 mJ/cm2 vs.35.55 mJ/cm2,P ＞ 0.05) compared with the female subjects.No significant difference was observed in the median value of UVA-or UVB-MED in subjects with skin type Ⅲ or Ⅳ between Han and Uygur nationality (all P ＞ 0.05).Also,no correlation was found in the median value of UVA-or UVB-MED with age or duration of outdoor exposure in the male or female subjects (all P ＞ 0.05).The lower reference limit was 33.38 J/cm2 for UVA-MED and 27.90 mJ/cm2 for UVB-MED in the population in Urumqi region.Conclusion Skin phototype may be an important determinant of MED.

Cutaneous squamous cell carcinoma (CSCC) is a kind of malignant tumor originated from keratinocytes within the epidermis and its appendages. Its etiology and pathogenesis are complex and unclear. The incidence of CSCC is increasing in the whole world, which makes the research on its pathogenesis increasing day by day. Epigenetics does not change genome sequence, but regulates gene expression by DNA methylation, histone modification, noncoding RNA, chromatin remodeling and so on. Its reversible and stable genetic characteristics will provide a new idea for the study of pathogenesis of CSCC.

Pruritus is one of the typical clinical manifestations of bullous pemphigoid (BP) . In recent years, researchers have gradually recognized that the histamine-independent itch pathway plays an important role in BP. Eosinophils, basophils, interleukin (IL) -31, IL-4, IL-13, thymic stromal lymphopoietin, periostin and substance P are all closely related to the occurrence of pruritus in BP. This review mainly elaborates research progress in mechanisms related to pruritus in BP.

Objective To detect the level of 5-hydroxymethyl-cytosine (5-hmc)in melanoma tissues,and to analyze the correlation between 5-hmc and the invasion,metastasis and prognosis of melanoma.Methods A streptavidin-peroxidase immunohistochemical method was used to detect the level of 5-hmc in 67 melanoma tissues and 20 pigmented nevi tissues.Univariate and multivariate analyses were performed with the Cox's proportional hazards regression model to analyze the correlation between the expression of 5-hmc and the prognosis of melanoma.Results The expression rate of 5-hmc was significantly lower in melanoma tissues than in pigmented nevus tissues (40.30％ [27/67] vs.75％ [15/20],22 =7.428,P =0.006).According to American Joint Committee on Cancer (AJCC) TNM staging system,the expression level of 5-hmc was significantly lower in the stage Ⅳ melanoma tissues than in the stage Ⅱ and stage Ⅲ melanoma tissues (x2 =4.416,P =0.036).Patients with lymph node metastasis showed significantly lower expression of 5-hmc compared with those without lymph node metastasis (x2 =5.902,P =0.015),and the level of 5-hmc expression significantly decreased along with the increase of Clark grade (x2 =4.828,P =0.028).There were no significant differences in the level of 5-hmc expression between patients of different ages,genders or nationalities (P ＞ 0.05).Multivariate Cox regression analysis showed that distant lymph node metastasis (HR:2.67,95％ CI:1.22-5.84),not receiving surgical resection (HR:0.41,95％ CI:0.18-0.95),and low expression of 5-hmc (HR:3.54,95％ CI:1.09-11.43)were independent risk factors for poor prognosis of melanoma.Conclusion 5-Hmc may participate in the invasion and metastasis of melanoma,and be associated with the prognosis of melanoma.

Objective:To understand the cognition of research integrity of in-service medical staff in a tertiary hospital in Xinjiang, provide possible reference for research integrity training.Methods:In March 2021, an electronic questionnaire survey was conducted to investigate the knowledge of scientific research integrity of in-service medical staff in a tertiary hospital in Xinjiang. T test and analysis of variance were used for univariate analysis, and multiple linear regression was used for multivariate analysis.Results:550 valid questionnaires were collected in total, and the overall awareness rate of scientific research integrity of in-service medical staff was less than 60%. Univariate analysis showed that there were differences in cognitive score of scientific research integrity among medical staff who participating in different scientific research activities ( P<0.05). Multivariate analysis showed that the educational level of the in-service medical staff, whether they participated in scientific research training, whether they had the qualifications of graduate student supervisor, the interaction between educational level and participation in scientific research training was statistically significant ( P<0.05). LSD test of educational level and participation in scientific research training showed that there was a statistically significant difference in educational level of participation in scientific research training ( P<0.01). Conclusions:The cognition of research integrity on in-service medical staff in a tertiary hospital in Xinjiang need to be enhanced, and their knowledge of research integrity need to be improved. Various measures should be carried out to strengthen the research integrity education and training, so as to improve the level of medical staff’s cognition of research integrity, and improve the medical staff’s attitudes of research integrity.

Objective:To understand the research ability, cognition, and training needs of clinical medical staff in a grade A tertiary hospital in Xinjiang and to analyze the influencing factors.Methods:A convenience sampling method was applied to survey the clinical medical staff of our hospital with a questionnaire including general information, a self-assessment scale of research ability, and a survey of research cognition and training needs. A total of 618 questionnaires were collected with 609 valid returned responses, resulting in an effective return rate of 98.54%. Univariate and multiple linear regression analysis were applied to analyze the influencing factors of the total score of clinical medical staff's research ability.Results:The total score of research ability of 609 clinical medical personnel was 60.73±13.59. The results of multiple linear regression showed that participation in scientific research conferences, enthusiasm for scientific research activities, and the need for scientific research training all had positive effects on the self-assessment of scientific research ability, which together explained 52% of the total variance (adjusted R2=0.520, P<0.001). The top three " very important" options for medical staff research training were data analysis, research design, and research topic selection. Conclusions:Medical staff research skills need to be improved and there is a strong need for research training. Managers should refine scientific research management initiatives and provide hierarchical and targeted scientific research training to improve the overall medical staff's scientific research literacy and research ability, thereby promoting the progress of medical care in hospitals.
