Objective To explore the difference of cardiovascular risk factors and coronary artery lesion between Hui nationality and Han nationality patients with premature coronary heart disease. Methods A total of 316 patients with premature coronary heart disease were divided into two groups, including the Hui group (78 cases) and the Han group (238 cases). Eight risk factors for premature coronary heart disease (including age, gender, body mass index, familial heredity, diabetes, hypertension, dyslipidemia and smoking history) and coronary artery lesion characteristics were compared between the two groups. Results Compared with the Han group, the Hui group had a higher prevalence of smoking history and myocardial infarction, but a lower prevalence of angina (Plt;0.05). Type A disease was the major type in both Hui and Han groups. Compared with the Han group, the rate of type C were higher. Single-vessel lesion was the major lesion in both Hui and Han groups. The incidence of three-vessel lesion in the Han group was significantly lower than that in the Hui group. Gensini score in the Hui group was higher than that in the Han group, with a significant difference (Plt;0.05). Conclusion Hui patients with premature coronary artery disease are more than Han patients with premature coronary artery disease in proportions of smoking, diabetes, and the lesions of the left anterior descending artery, the right coronary artery disease, three-vessel disease rate, and C-type lesions. The coronary artery disease of the Hui group is more serious.

Objective To analyze the risk factors and clinical characteristics of patients in Uyghur and Han nationalities with pulmonary thromboembolism (PTE), who were hospitalized in past 7 years in the First Affiliated Hospital of Xinjiang Medical University, so as to investigate differences of risk factors between two nationalities. Methods Through retrospective study, clinical characteristics of PTE patients hospitalized from 2004 to 2010 were analyzed. T-test and chi-square test were used to conduct statistic analysis. Results a) A total of 516 patients (mean age 58.7±14.8 years old) with complete clinical materials were included, of whom 360 were Han nationality (69.8%, mean age 63.5±15.5 years old) and 156 were Uyghur nationality (30.2%, mean age 52.8±14.3 years old). In Han nationality, the peak age of PTE onset was above 70 years of age, while in Uyghur nationality it was 60 to 69 years of age; b) No significant difference was found in the clinical characteristics between the two nationalities; and c) The commonly acquired risk factors for PET patients in both nationalities possibly were age at or over 40 years old, obesity, embolism history and hyperlipidemia. The main risk factor of PTE was obesity in Uyghur nationality, while that was smoking in Han nationality. Conclusion The most common acquired risk factors and basic diseases of PTE patients are probably the age at or over 40 years old, obesity, embolism history and hyperlipidemia, and obesity is commonly seen in Uyghur nationality. A large number of further case-control studies are needed to further confirm this conclusion.

The present study was aimed to explore the relationship of transforming growth factor (TGF) β3 gene SfaNI polymorphism (rs3917201 locus) and non-syndromic cleft lip with or without cleft palate (NSCL/P) in people of the Uygur's Nationality and Han's in Xinjiang, China. TGFβ3 gene fragment including SfaNI was amplified and purified as the template of the primer extension reaction thenafter. The single base extension reaction was carried out using SNP specific extension primer. The products were purified and analyzed by MALDI-TOF. The test showed that there were not significantly different frequencies of AA, AG, GG genotypes and alleles between the whole NSCL/P group and the whole control group (P>0.05).Within the Uygurs or Hans, the frequencies of genotypes between the whole NSCL/P group and the whole control group were not significantly different(P>0.05). The distributions of the A, G alleles between the NSCL/P group and the control group were not significantly different within the Uygurs (P>0.05), but significant different within the Hans (P<0.05). In all the NSCL/P patients, frequencies of genotypes and alleles were not significantly different between Uygurs and Hans (P>0.05), and not significantly (P>0.05) either between Uygurs and Hans in all the healthy persons. The results proved that TGFβ3 gene SfaNI polymorphism may not be related to NSCL/P in Xinjiang Uygur people, while the occurrence of NSCL/P in Han population may be related to frequency of the A and G allele of SfaNI polymorphism.
ObjectiveTo comparatively analyze risk factors that influence the postoperative recurrence and distant metastasis between Xinjiang Uygur and Han women with breast cancer. MethodsThe clinical data of Han and Uyghur women with diagnosis of breast cancer at Ⅰ-Ⅲ period were completely collected for retrospective analysis. Then logistic regression (univariate and multivariate) was performed for analyzing the risk factors that influenced recurrence and metastasis. ResultsA total of 728 patients were included. The recurrence and metastasis rates among Uyghur and Han patients 3 years after surgery were 28.4%, 9.8%, respectively, including local recurrence[11 Uyghur cases (6.5%) and 9 Han cases (1.6%)] and distant metastasis[37 Uyghur cases (21.8%) and 45 Han cases (8.0%)]. Significant differences were found between the two groups in tumour size and time from symptom occurrence to clinical visits (P<0.05). Pathological type, tumour size, axillary lymph node metastasis, clinical stage, ER and PR expression, and whether to accept a regular postoperative adjuvant therapy were associated with the recurrence and metastasis rate among the patients with breast cancer at Ⅰ-Ⅲ period (P<0.05). The results of multivariate logistic regression analysis showed that, the recurrence and metastasis rate of Uyghur patients was higher than that of Han patients with a significant difference (P<0.01). Pathological type, tumour size, and axillary lymph node metastasis number were the risk factors used to predict postoperative recurrence and metastasis among Uygur and Han patients; while ER positive expression, adjuvant radiation and postoperative chemotherapy were protective factors. ConclusionThe recurrence and metastasis rate of Uyghur patients with breast cancer is higher than that of Han patients. Pathological type, tumour size, and axillary lymph node metastasis number are the risk factors of postoperative recurrence and distant metastasis; while ER positive expression, adjuvant radiation and postoperative chemotherapy may inhibit the recurrence and distant metastasis of breast cancer.
ObjectiveTo compare the outcomes of kidney transplantation (KT) between Tibetan and Han recipients.MethodsPatients greater than 18 years old, who had received the first ABO-compatible KT between April 2006 and March 2017, were retrospectively included. A propensity score matching (PSM) of Tibetans to Hans was performed by 1∶3 ratio. Survival, renal function and adverse events of the two groups were compared.ResultsOf the 1 820 patients who fit the screening criteria, 123 Tibetans and 357 Hans were included after PSM. The median follow-up time was 48 months. There was no statistically significant difference in death-censored grafts survival (P=0.061) or patients survival (P=0.440) between the two groups. The serum creatinine was higher in Tibetans than that in Hans within one year after KT (P<0.05), and the estimated glomerular filtration rate was lower in Tibetans than that in Hans within 5 years after KT (P<0.05), but no difference thereafter (P>0.05). The incidence of delayed graft function in Tibetan patients after operation was higher than that in Han patients (4.9% vs. 1.4%, P=0.037), but there was no significant difference in the incidence of acute rejection, infection, reoperation, or cancer between the two groups (P>0.05).ConclusionTibetans receiving KT achieve excellent and comparable long-term graft and patient survival to Hans, with similar long-term graft function.
Objective To study the differences of obstructive sleep apnea hypopnea syndrome (OSAHS)-related indexes between Uyghur and Han, and to provide evidence for the development of individualized treatment measures for different ethnic groups. Methods 224 Han OSAHS patients were collected from Guangdong Provincial Hospital of Chinese Medicine, and 178 Uygur OSAHS patients were collected from The First People’s Hospital of Kashi between January 2018 and December 2019. The collected data information included age, sex, nationality, body mass index (BMI), apnea hypopnea index (AHI), lowest oxygen saturation (LSaO2), OSAHS stage, mean corpuscular hemoglobin concentration (MCHC), triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), fasting blood glucose (FBG), and glycosylated hemoglobin (HbAlc). After using propensity matching scores to reduce confounding factors, differences in above indicators between different nationalities were compared. Results The mean values of MCHC, TC and HDL in Uygur OSAHS patients were lower than those in Han patients at the same stage, and the mean values of LSaO2 and LDL in mild and severe Uygur OSAHS patients were lower than those in Han patients at the same stage, with statistically significant differences (all P<0.05). There were no significant differences in AHI, TG, FBG or HbAlc between Uygur and Han patients with OSAHS. Conclusion There are significant differences in LSaO2, LDL, MCHC, TC and HDL between Uygur and Han Chinese patients with OSAHS.
