ABSTRACT
【Objective】 To analyze the clinical characteristics of children with ammonium urate stones in Xinjiang, so as to provide reference for the prevention and treatment of this disease. 【Methods】 The clinical data of all children with ammonium urate stones admitted to the People’s Hospital of Xinjiang Uygur Autonomous Region from 2016 to 2021 were retrospectively analyzed, including age, sex, body mass index, stone site, stone size, stone component, urine pH, urine culture and biochemical examination results. The serum total protein, albumin, sodium, potassium, calcium, magnesium, uric acid and urine pH were compared between the pure and mixed groups. 【Results】 A total of 61 children (31.6%) had ammonium urate stones, their average age was (4.05±3.37) years, and the male to female ratio was 2.21∶1. Among them, there were 37 cases (60.7%) of renal calculi and 50 cases (82.0%) of upper urinary calculi. The most common component of mixed ammonium urate stones was calcium oxalate, including calcium oxalate monohydrate, calcium oxalate monohydrate and calcium oxalate dihydrate. Compared with mixed type, children with pure stone type had a younger age (P=0.001) and a smaller stone size (P=0.003). Positive urine culture was detected in 14 cases (23.0%), 7 of which (50% were infected with Escherichia coli, and 11 (78.6%) with non-urease bacteria. 【Conclusion】 Non-urease bacteria are the main pathogens of urinary tract infection in children with ammonium urate stones. The incidence is higher in boys, and the most common stone location is upper urinary tract. Calcium oxalate is the most common mixed component. Pure type is more common in young children and the stones are relatively small.
ABSTRACT
ObjectiveTo investigate the association between ZJU index and the onset of nonalcoholic fatty liver disease （NAFLD） in the Uygur population and the value of ZJU index in predicting the risk of NAFLD. MethodsThe Uighur community of The 51st Regiment of The Third Division of Xinjiang Kashgar Corps was selected as the investigation site， and the Uygur residents who lived in this area and had an age of >18 years were selected as subjects. Follow-up studies were conducted in 2019， 2020， and 2021， and the investigation of outcomes was completed in June to August of 2021. Finally 10 597 subjects were enrolled for analysis. The Kruskal-Wallis H test was used for comparison of continuous variables between groups， and the chi-square test was used for comparison of categorical variables between groups. The subjects were divided into Q1-Q4 groups according to the level of ZJU index. The Kaplan-Meier curve was used to predict the incidence rate of NAFLD， and the Cox regression model was used to analyze the association between ZJU index and the risk of NAFLD； the area under the ROC curve （AUC） was used to evaluate the value of ZJU index in predicting the risk of NAFLD. ResultsDuring the median follow-up time of 4.92 years， the incidence rate of NAFLD was 9.4% （992/10 597） among the study population. After adjustment for multiple factors， there was a significant increase in the risk of NAFLD with the increase in ZJU index， with a hazard ratio of 2.55 （95% confidence interval ［CI］： 1.60 — 4.06）， 7.32 （95%CI： 4.78 — 11.20）， and 21.74 （95%CI： 14.32 — 33.00）， respectively （all Ptrend<0.001）. The ROC curve showed that ZJU index had a higher value in predicting NAFLD （AUC=0.816）， and the male subgroup had a significantly higher predictive accuracy of ZJU index than the female subgroup （AUC： 0.829 vs 0.809）. ConclusionZJU index is a predictive factor for the onset of NAFLD in the Uygur population in rural areas of Xinjiang and has a good value in predicting the risk of NAFLD.
ABSTRACT
AIM: To investigate the myopia and hyperopia reserve among Uyghur children aged 6～12 in Yecheng county of Xinjiang.METHODS: In a cross-sectional study, a total of 50 151 Uyghur students aged 6～12 years from Yecheng county of Xinjiang underwent comprehensive vision screening, including automatic computer optometry, indoor remote light box E-word standard logarithmic visual acuity chart(GB 11533), to measure the naked eye distant vision and corrected vision with lens.RESULTS: From October 2021 to January 2022, the spherical equivalent(SE)of 6-12 year old Uyghur myopic children was -0.875(-1.625, -0.625)D, and the detection rate of myopia was 6.75%(3384/50151)in Yecheng county of Xinjiang. The SE of the myopic children aged 6～12 was -0.75(-1.125, -0.625)D, -0.75(-1.125, -0.625)D, -0.875(-1.125, -0.625)D, -0.875(-1.375, -0.625)D, -0.875(-1.6, -0.625)D, -0.875(-1.625, -0.625)D, -1.25(-2.125, -0.75)D, respectively. The SE of non-myopic children aged 6～12 was +0.25(-0.125, +0.5)D, and the detection rate of insufficient hyperopia reserve was 75.51%. The SE of the non-myopic children aged 6～12 was +0.25(-0.125, +0.5)D, +0.25(0, +0.5)D, +0.125(-0.125, +0.5)D, +0.25(-0.125, +0.5)D, +0.125(-0.125, +0.5)D, +0.125(-0.125, +0.5)D, +0.25(-0.125, +0.625)D, respectively. The detection rates of myopia children aged 6～12 were 6.78%, 5.64%, 5.72%, 5.36%, 5.01%, 6.82%, 12.14%, respectively. The detection rates of insufficient hyperopia reserve children aged 6～12 were 91.67%, 92.04%, 92.91%, 83.85%, 68.89%, 54.01%, 26.71%, respectively. The detection rate of insufficient hyperopia reserve in non-myopic girls aged 9～12 years old was higher than that in boys(χ2=8.94, 19.99, 19.91 and 39.11, all P<0. 05); The detection rate of myopia in 10～12 year old girls was higher than that in boys(χ2=5.402, 8.493 and 36.9711, all P<0. 05).CONCLUSIONS: The prevalence rate of myopia among Uyghur children aged 6～12 years in Yecheng county of Xinjiang was 6.75%, while the detection rate of insufficient hyperopia reserve in non-myopic children reached up to 75.51%. It is predicted that there are a large number of children at high risk of myopia. Therefore, early monitoring of hyperopia reserve in children is vital for myopia prevention and control strategy.
ABSTRACT
Hepatitis D is a global public health issue, and the infection rate and genotype of HDV infection vary greatly across different regions. The overlapping infection of hepatitis D virus (HDV) in patients with chronic hepatitis B virus (HBV) infection can accelerate disease progression, but hepatitis D has not been taken seriously to a large extent. Xinjiang in China is an area with a high incidence rate of hepatitis B, but there is a lack of research on hepatitis D. This article discusses the prevalence of HDV infection in Xinjiang and briefly reviews the prevalence rate of HDV infection in Xinjiang, the molecular epidemiology of HDV among different ethnic groups, and the current status of HDV infection in neighboring countries, so as to provide a reference for the conduct of molecular epidemiological research on HDV and disease prevention and control in Xinjiang.
ABSTRACT
Objective To investigate the association between gallstones (GS) and metabolic syndrome (MS) in southern Xinjiang, China, and to provide experience for the prevention and control of metabolic diseases in southern Xinjiang. Methods The patients with GS who visited First Division Hospital, Second Division Korla Hospital, and Third Division Hospital of Xinjiang Production and Construction Corps from March 2015 to March 2019 were enrolled as case group, and cluster sampling was used to select the individuals who underwent physical examination in Third Division 51st Regiment Hospital during the same period of time were enrolled as control group. According to inclusion and exclusion criteria, 1140 cases were enrolled in each group after 1∶ 1 matching based on age and sex. The t -test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the influencing factors for GS. Dummy variables were included by logistic regression to evaluate multiplicative interaction between MS components, and the parameter estimate and covariance matrix of the logistic regression model and interaction calculation table were used to calculate and evaluate additive interaction between MS components. Results The risk of GS in MS patients was 2.33 times that in non-MS patients (odds ratio [ OR ]=2.33, 95% confidence interval [ CI ]: 1.86-2.92). In addition, the components of MS also increased the risk of GS, including blood glucose ( OR =2.94, 95% CI : 2.36-3.68), blood pressure ( OR =1.50, 95% CI : 1.26-1.80), blood lipids ( OR =1.48, 95% CI : 1.25-1.75), and body mass index ( OR =1.44, 95% CI : 1.21-1.70). After adjustment for multiple factors, the risk of GS gradually increased with the increase in the number of metabolic abnormalities, i.e., one abnormality ( OR =1.55, 95% CI : 1.22-1.99), two abnormalities ( OR =2.13, 95% CI : 1.66-2.72), three abnormalities ( OR =3.48, 95% CI : 2.59-4.69), and four abnormalities ( OR =4.65, 95% CI : 2.79-7.84). No additive or multiplicative interaction was found between MS components. Conclusion GS is closely associated with MS in southern Xinjiang, and the risk of GS gradually increases with the increase in MS components. No additive or multiplicative interaction is found between GS and MS components.
ABSTRACT
OBJECTIVES@#To study the genetic polymorphism and population genetic parameters of 16 X-STR loci in Xinjiang Uygur population.@*METHODS@#The Goldeneye® DNA identification system 17X was used to amplify 16 X-STR loci in 502 unrelated individuals (251 females and 251 males). The amplified products were detected by 3130xl genetic analyzer. Allele frequencies and population genetic parameters were analyzed statistically. The genetic distances between Uygur and other 8 populations were calculated. Multidimensional scaling and phylogenetic tree were constructed based on genetic distance.@*RESULTS@#In the 16 X-STR loci, a total of 67 alleles were detected in 502 Xinjiang Uygur unrelated individuals. The allele frequencies ranged from 0.001 3 to 0.572 4. PIC ranged from 0.568 8 to 0.855 3. The cumulative discrimination power in females and males were 0.999 999 999 999 999 and 0.999 999 999 743 071, respectively. The cumulative mean paternity exclusion chance in trios and in duos were 0.999 999 997 791 859 and 0.999 998 989 000 730, respectively. The genetic distance between Uygur population and Kazakh population was closer, and the genetic distance between Uygur and Han population was farther.@*CONCLUSIONS@#The 16 X-STR loci are highly polymorphic and suitable for identification in Uygur population, which can provide a powerful supplement for the study of individual identification, paternity identification and population genetics.

【Objective】 To investigate the distribution frequency and characteristics of Rh and Kell erythrocyte blood group antigens in Uygur population in Xinjiang, and to explore the molecular mechanism of K gene positive patients, so as to build a local rare blood group bank and improve the ability of clinical blood security. 【Methods】 From June 2018 to February 2020, blood samples of 4 000 unrelated Uygur healthy individuals from the Medical Examination Center of our hospital and other cooperative hospitals across the autonomous region were selected. Rh and Kell blood group antigens were detected using K/Rh antigen microcolumn gel cards. The exons of Kell gene were amplified by PCR and then subjected to electrophoresis and direct sequencing to investigate the molecular mechanism. 【Results】 In Xinjiang Uygur healthy population, 1) The RhD negative rate was 5.675% (227/4 000), including 5 phenotypes; RhD positive rate was 94.325% (3 773/4 000), including 9 phenotypes, which were in line with Hardy-Weinberg equilibrium distribution. The C/E antigen frequency in RhD negative and positive patients was 13.216%/4.185% vs 52.876%/25.788% (PC, g. 412A>G, exon 6, g. 133C>T, and g. 189T>C, respectively, two of which caused changes in amino acid sequence: alanine at position 193 to methionine (p.Ala193Met) and alanine 423 to valine (p.al423Val). The prediction of RNA secondary structure and protein conformation after mutation using relevant biological information software found that the mutation caused changes in RNA secondary structure, free energy, protein conformation and function. 【Conclusion】 The frequency of RhD antigen negative in Xinjiang Uygur population was higher than that in other ethnic groups, and the distribution of C/E antigen was different in D antigen negative/positive patients. The distribution of K antigen in Kell blood group system was higher than that in other ethnic groups (P<0.05). The primary and secondary structure changes of nascent peptide chain caused by a single point mutation in Kell gene may be one of the molecular mechanisms of K antigen positivity.

Although tick-borne diseases can be found almost in all regions in China, they are mainly distributed in Xinjiang, Inner Mongolia, Heilongjiang and other border areas. Tick-borne diseases in Xinjiang are rising year by year with a serious situations recently, and there are specific features in the distribution and characteristics of pathogens. This article reviews the etiology, epidemic status and clinical manifestations of major tick-borne infectious diseases in Xinjiang.
ABSTRACT
@#AIM: To investigate the status of astigmatism in children and adolescents aged 7-19 years in some areas of Xinjiang, and to analyze the distribution of astigmatism in children and adolescents in Xinjiang.METHODS: Cross-sectional study. This study took a purposive sampling survey of 41 schools in some areas of Xinjiang, including 20 primary schools and 21 middle schools, from May 2019 to December 2019. A total of 71 838 children and adolescents were included as the survey objects for relevant eye examinations.RESULTS: Among 71 838 students, 35 888 were found to have astigmatism(column ≤ -0.50D), and the astigmatism detection rate was 49.96%. The differences of astigmatism detection rate among different ages, genders, education levels, regions and ethnic groups were statistically significant(all <i>P</i><0.001). The detection rate of astigmatism increased with age from 7-16 years old, and reached the highest rate of 57.60% at 16 years old. The detection rate of astigmatism decreased from 16-19 years old, and the overall detection rate of astigmatism increased with age. With the increase of education level, the detection rate of astigmatism increases, and the detection rate of male astigmatism(51.25%)is higher than that of female astigmatism(48.62%). The detection rate of astigmatism in provincial capital cities(50.99%)is higher than that in non-provincial capital cities(48.05%); the detection rate of astigmatism in Han(53.41%)was higher than that in Uyghur(40.17%), Kazakhs(48.23%), Kyrgys(45.56%)and Hui(48.87%). The astigmatism type was mainly with-the-rule astigmatism(74.53%), and with the increase of age, the composition ratio of with-the-rule astigmatism decreased, while the composition ratio of against-the-rule astigmatism and oblique astigmatism increased. The final results of Logistic regression analysis showed that age, gender, nationality, region and education level were all influential factors of astigmatism.CONCLUSION: The prevalence of astigmatism in children and adolescents aged 7-19 years in some areas of Xinjiang is 49.96%, and the astigmatism is mainly with-the-rule astigmatism(74.53%). Age, gender, nationality, region and education level are the influential factors of astigmatism.
ABSTRACT
Objective@#To analyze the surveillance results of common diseases among primary and middle school students in Xinjiang Production and Construction Corps in 2020, so as to provide the evidence for formulating the control measures for common diseases among primary and middle school students. @*Methods@#The comprehensive health surveillance data of 31 467 primary and middle school students were collected from 132 schools in 14 divisions of Xinjiang Production and Construction Corps in 2020, and the prevalence of poor vision, overweight and obesity, dental caries, malnutrition and elevated blood pressure were descriptively analyzed.@*Results@#The 31 467 students included 15 580 boys ( 49.51% ) and 15 887 girls ( 50.49% ). There were 19 632 students ( 62.39% ) from urban areas and 11 835 ( 37.61% ) from suburban areas, and there were 11 371 primary students ( 36.14% ), 11 169 junior high school students ( 35.49% ) and 8 927 high school students ( 28.37% ). The detection rates of poor vision, overweight and obesity, dental caries, elevated blood pressure, and malnutrition were 57.22%, 29.69%, 27.57%, 15.03%, and 4.81%, respectively. The detection rates of overweight and obesity ( 36.07% vs. 23.45%, P<0.05 ) and malnutrition ( 5.71% vs. 3.93%, P<0.05 ) were significantly higher, while the detection rates of poor vision ( 51.61% vs. 62.72%, P<0.05 ), dental caries ( 24.46% vs. 30.63%, P<0.05 ) and elevated blood pressure ( 14.61% vs. 15.43%, P<0.05 ) were significantly lower in boys than in girls. The detection rates of overweight and obesity ( 30.17% vs. 28.91%, P<0.05 ) and poor vision ( 61.55% vs. 50.04%, P<0.05 ) were significantly higher, while the prevalence rates of malnutrition ( 4.55% vs. 5.24%, P<0.05 ), dental caries ( 24.47% vs. 32.73%, P<0.05 ) and elevated blood pressure (14.66% vs. 15.63%, P<0.05) were significantly lower in students from urban areas than from suburban areas.

ABSTRACT
AIM: To understand the status of poor vision and analyze the main influencing factors among primary and secondary school students in a division of the Xinjiang Production and Construction Corps, and provide a scientific basis for prevention and control of poor vision.METHODS: A total of 12 primary and secondary schools in a divisional urban district and regiment field of the Xinjiang Production and Construction Corps were chosen using stratified cluster random sampling from August to October 2020. A total of 2 982 primary and secondary school students were selected for visual inspections and questionnaires. Logistic regression analysis was used to explore the influencing factors of poor vision.RESULTS: The rate of poor vision was 65.66% among 2 982 primary and secondary school students in the division of the Xinjiang Production and Construction Corps, with the majority severe poor vision. Furthermore, the rates of poor vision were higher in girls(70.17%)than that in boys(61.47%)(χ2=4.993, P<0.001)and the urban area(70.03%)were higher than the rural area(58.96%)(χ2=38.680, P<0.001)and the Han nationality students(66.83%)were higher than Uyghur students(52.82%)(χ2=19.772, P<0.001). The risk of poor vision increased with age(χ2trend =300.144, P<0.001), and by the age group ≥18 years old, the rate of poor vision reached 80.47%. The results of the multivariate analysis showed that the women, the age≥13 years old, writing and reading duration every day ≥2h, cram school on weekends and presence of myopia in parents increases the risk of poor vision, increase the outdoor exercise time, sleep time ≥8h, and do eye exercises every day can reduce the occurrence of poor vision.CONCLUSION: Poor vision rate of primary and secondary school students in the division of the Xinjiang Production and Construction Corps is higher than that of many regions in the country. Girls with the age(≥13 years old)whose parents are myopic should receive special attention. Increasing outdoor exercise time, doing eye exercises every day, and keeping your eyes more than one foot away from books when reading and writing is effective in preventing poor vision.
ABSTRACT
Objective:To investigate the correlation between serum indexes of children with simple obesity in Xinjiang area and the renin-angiotensin-aldosterone (RAS)system, thus providing evidence to clarify the pathogenesis of childhood obesity.Methods:It was a cross-sectional study involving 41 children with simple obesity (case group) and 41 age-matched healthy children (control group) through the cluster random sampling in Tacheng area of Xinjiang.The mean age of in both groups was (10.04±1.66) years and (10.12±1.68) years, respectively.Serum adipokines, insulin level and RAS indexes between groups were compared by the Student′s t test.The correlation between serum adipokines and RAS activity in children with simple obesity was assessed by the Pearson′ s correlation test. Results:The serum adiponectin(APN) level[(7.90±1.96) μg/L vs.(8.87±1.61) μg/L, P=0.017]was significantly lower in case group than that of control group, while leptin[(6.81±1.88) ng/L vs.(5.87±1.79) ng/L, P=0.023]and resistin levels[(12.61±3.63) ng/L vs.(10.18±3.07) ng/L, P=0.002] were significantly higher.RAS indexes, including the renin[(35.78±10.08) ng/L vs.(29.24±10.69) ng/L, P=0.007], aldosterone (ALD)[(106.90±20.18) ng/L vs.(97.68±17.60) ng/L, P=0.028] and angiotensin-Ⅱ (Ang-Ⅱ)[(55.65±10.37) ng/L vs.(48.78±9.26) ng/L, P=0.002] levels were significantly higher in case group than those of control group.In the case group, serum APN level was negatively correlated with renin, ALD and Ang-Ⅱ levels ( r=-0.646, -0.752, -0.839, all P<0.001), while serum leptin and resistin levels were positively correlated with renin, ALD and Ang-Ⅱ levels ( r=0.940, 0.871, 0.875; 0.877, 0.892, 0.914, all P<0.001). Conclusions:Serum adipokine in school-age children with simple obesity in Xinjiang area is dysregulated, which interferes with the activity of RAS.
ABSTRACT
Objective:To investigate the effects of different chimerism strategies and different immune ways on the two antigen-dominant regions of Xinjiang hemorrhagic fever virus (XHFV) glycoprotein.Methods:The 5' end was added or not added with interleukin-2 (IL-2) signal peptide and the general-purpose auxiliary T cell epitopes as different design strategies. GcⅠ and GcⅡ and the epitopes previously identified on GcⅠ (Gc 233-248, Gc 241-256 and Gc 281-296) were fused and constructed into the eukaryotic expression vector pVAX1 and the prokaryotic expression vector pET-28a. The recombinant prokaryotic plasmid transformed into E.coli BL21 was induced and purified, and the recombinant eukaryotes were extracted by indirect immunofluorescent assay. BALB/c mice were immunized by protein immunity, gene immunity, and DNA prime-protein boost immunity. The IgG antibody level was measured by ELISA. The immune effect was evaluated by the proliferation of T-lymphocytes and the content of cytokines in the spleen. Results:The results of double enzyme digestion and sequencing showed that eight recombinant plasmids were successfully constructed, and the recombinant eukaryotes were successfully expressed in vitro by fluorescence microscopy. After three times of immunization, the IgG level and the proliferation of T-lymphocytes in the spleen of mice in the experimental group were significantly higher than those in the control group ( P<0.01). The mass concentration test results of Th2 cytokines IL-4 and Th1 cytokines interferon-gamma (IFN-γ) revealed that the response of the DNA prime-protein boost immunity was biased to Th1. Conclusions:The multi-epitope chimeric vaccine of XHFV glycoprotein was successfully constructed, and the target antigen could be expressed effectively in vivo. The immune groups stimulated stronger humoral and cellular immune responses compared with the control group. Among them, the immune effect of pVAX1-ST(GcⅠe+GcⅡ) combined with recombinant protein r(GcⅠe+GcⅡ) was the best, and it is expected to be a new candidate vaccine for XHFV.

There was no significant difference in the prevalence among people between different sexes, with and without coronary heart disease, smoking or not, different ultraviolet irradiation time (all at P>0.05). Multiple logistic regression analysis showed that age (50-<60 years old: [ OR=39.93, 95% CI: 20.77-76.77; 60-<70 years old: OR=3.81, 95% CI: 2.05-7.08; 70-<80 years old: OR=1.72, 95% CI: 0.92-3.22]), hypertension ( OR=1.54, 95% CI: 1.13-2.11) and hyperlipidemia ( OR=1.41, 95% CI: 1.10-2.03) were independent risk factors for cataract. Conclusions:The incidence of cataract in the Jiu Shi Hospital of Xinjiang Production and Construction Corps and people aged 50 and over in Emin County is higher than that in other parts of China, in which age, hypertension and hyperlipidemia are independent risk factors for cataract.
ABSTRACT
Objective To investigate the association of the polymorphisms of the FGB gene rs4220 and rs1044291 loci with plasma fibrinogen (Fg) level and gallstones in Xinjiang, China. Methods Blood samples were collected from 150 Uygur and Han patients with gallstones and 150 Uygur and Han individuals without gallstones who were hospitalized or underwent physical examination in The People's Hospital of Xinjiang Uygur Autonomous Region from December 2017 to May 2020. Plasma Fg level was measured, and based on the previous results of whole exon sequencing of the FGB gene, the SNaPshot method was used to identify the genotype at rs4220 and rs1044291 loci of the FGB gene. The t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; a multivariate logistic regression analysis was used to investigate the association between each variable and gallstones. Results For the Chinese Han population, the gallstones group had a significantly higher plasma Fg level than the control group [2.90 (2.43-3.49) g/L vs 2.47 (2.06-3.02) g/L, Z =-3.62, P 0.05). For the Chinese Han population, the subjects carrying GG genotype at the rs4220 locus in the gallstones group had a significantly higher plasma Fg level than those in the control group [2.84(2.32-3.61) g/L vs 2.34(2.05-2.75) g/L, Z =-3.04, P 0.05). Conclusion The influence of FGB gene polymorphism on plasma Fg level may be associated with race, and FGB gene polymorphisms at the rs4220 and rs1044291 loci may be involved in the pathogenesis of gallstones by regulating Fg level in the population in Xinjiang.

Objective:To investigate the application of radiotherapy and the basic situation of teaching and scientific research in Xinjiang.Methods:A unified questionnaire was adopted, distributed and collected by mail, instant messaging software and telephone. The basic situation of all radiotherapy affiliations in the whole region was counted.Results:The questionnaire coverage rate was 100% with a recovery rate of 100%. In 2020, 17 affiliations operated radiotherapy in Xinjiang, including 23 linear accelerators, 1 cobalt-60 therapeutic machine, 3 gamma knives, 6 post-installed therapeutic machines, 13 special analogue positioning machines, 46 treatment planning systems, and 103 sets of radiotherapy quality control equipment. It was estimated that the number of radiotherapy equipment for one million people in the whole region was approximately 0.84. In Xinjiang, 359 radiotherapy personnel were registered, including 220 physicians, 49 physicists and 90 technicians. A total of 1 270 beds were available, with an average daily treatment volume of approximately 1 255 person-times. From 2016 to 2021, 17 affiliations have undertaken 9 National Natural Science Foundation of China and 49 provincial and ministerial projects. Nineteen doctoral degrees and 87 master′s degrees were accredited. These affiliations participated in the publication of 25 articles in Chinese Journal of Radiation Oncology, of which 18 were published as the first authors and/or corresponding authors.Conclusions:The radiotherapy work in Xinjiang has developed rapidly in recent years, but there is still a certain gap with the national average level. At the same time, several problems still exist in the whole region, such as regional differences, unbalanced allocation of radiotherapy resources and scientific research and teaching resources, which need further improvement.
ABSTRACT
The homology of medicine and food has long been recognized in China， and the medicinal and edible resources are often employed to prevent and treat diseases or maintain health in traditional Chinese medicine （TCM）. Due to the unique geographical and climatic conditions， the Xinjiang Uygur Autonomous Region （hereinafter referred to as Xinjiang） is blessed with abundant medicinal and edible resources， like Rosae Rugosae Flos， Punica granatum， and Amygdalus communis， which have been widely used by local ethnic communities as medicine in light of the remarkable pharmacological activities， guaranteeing their health condition to some extent. This paper collected the relevant articles from China National Knowledge Infrastructure （CNKI） database through the keyword and full-text search with the medicinal and edible resource Rosae Rugosae Flos as the search term， and the subsequent analysis revealed that the medicinal and edible resources in Xinjiang has a wide range of applications in food， medicine， and ecological protection. This paper further explored their research value， status， and prospects， so as to provide some references for the rational， effective， and sustainable development and utilization of these medicinal and edible resources in Xinjiang， thus better achieving "poverty alleviation" and "rural revitalization"， popularizing TCM culture， and building a healthy China.
ABSTRACT
Xinjiang is rich in resources of medicinal plants， which are widely used in ethnic medicines because of their remarkable pharmacological activities and safeguard lives and health of people of all ethnic groups in Xinjiang and local health services. The ethnic medicines in Xinjiang are harmonious but different and united in diversity. Besides， they also promote each other and develop together， constituting an inseparable and important part of traditional Chinese medicine in China. Among them， Uygur medicine， Kazak medicine， Kirgiz medicine， Tajik medicine， and Tatar medicine are predominant in regional characteristics， but the development of the ethnic medicine industry in Xinjiang is backward. In recent years， Xinjiang ethnic medicines have been reported to possess significant pharmacological activities， which deserve further development and investigation. However， the development of ethnic medicines in Xinjiang has been restricted severely due to the lack of effective inheritance of practice and experience， weak basic research， insufficient brand awareness， resource destruction， etc. This study analyzed the medicinal value， development status， and prospects of Xinjiang ethnic medicines and summarized the problems in the modernization of ethnic medicines in Xinjiang to provide some scientific references for the follow-up development and clinical application of Xinjiang ethnic medicines， aiming to promote the sustainable development of traditional ethnic medicines of China.
ABSTRACT
OBJECTIVE：To study the relationship of polymorphism of clopidogrel absorption and metabolism related genes CYP2C19（* 2，* 3，* 17），ABCB1 C3435T and PON1 Q192R in patients with coronary heart disease in Xinjiang Uygur Autonomous Region ，and to explore the characteristics of population and combined diseases. METHODS ：A total of 1 126 patients with coronary heart disease who underwent clopidogrel absorption and metabolism related gene testing during hospitalization in the First Affiliated Hospital of Xinjiang Medical University from January 2016 to June 2020 were included as the study subjects. The gender，age，body mass index （BMI），nationality and the proportion of combined with hypertension and diabetes were compared among different CYP2C19 metabolic phenotypes and ABCB1 C3435T and PON1 Q192R genotypes. RESULTS ：Among 1 126 patients，1 126 had CYP2C19 * 2，* 3 and * 17 genotypes，1 109 had ABCB1 C3435T genotype and 1 123 had PON1 Q192R genotype. The distribution of each genotype was in line with Hardy-Weinberg balance （P＞0.05）. There were 66（5.86％）， com 459（40.76％），476（42.27％） and 125（11.10％）patients with CYP2C19 ultra-rapid metabolizer （UM）， extensive metabolizer（EM），intermediate metabolizer （IM）and poor metabolizer（PM），respectively. The proportion of patients with UM metabolism phenotype with BMI ＞24 was significantly higher than those of patients with IM and PM metabolism phenotypes （P＜0.05）. The proportion of Han nationality patients with UM metabolic phenotype was significantly lower than those of patients with EM ，IM and PM metabolic phenotypes （P＜0.05）；the proportion of Uygur nationality was significantly higher than that of patients with EM ，IM and PM metabolic phenotypes （P＜ 0.05）. There were 355，538 and 216 patients with ABCB1 C3435T wild-type（CC），heterozygous（CT）and mutant homozygous （TT）genotypes，respectively；the proportion of Han nationality in TT genotype patients was significantly lower than that in CC and CT genotype patients （P＜0.05），and the proportion of Uygur nationality was significantly higher than that in CC and CT genotype patients （P＜0.05）；the proportion of TT genotype patients with diabetes was significantly higher than that of patients with CT genotype （P＜0.05）. There were 365，519 and 239 patients with PON1 Q192R wild-type（GG），heterozygous（GA）and mutant homozygous （AA），respectively；the proportion of Han nationality in AA genotype patients was significantly lower than that in GG and GA genotype patients （P＜0.05），and the proportion of Uygur nationality was significantly higher than that of GG and GA genotype patients （P＜0.05）；the proportion of Han nationality and BMI ≤24 in patients with AA genotype were significantly lower than those with GA genotype （P＜0.05），and the proportion of Uygur nationality ，BMI＞24 and hypertension were significantly higher than those in GA genotype patients （P＜0.05）. CONCLUSIONS ：There are significant nationality differences among patients with different CYP2C19 metabolic phenotypes and ABCB1 C3435T and PON1 Q192R genotypes. In addition，patients with BMI ＞24 account for high proportion among CYP2C19 UM metabolism genotype ；patients with diabetes account for high proportion among ABCB1 C3435T TT genotype ；patients with BMI ＞24 and hypertension account for high proportion among PON1 Q192R AA genotype.
ABSTRACT
Objective To understand the radioactivity level of food surrounding a uranium mine in Xinjiang, to supplement the baseline database of food radionuclides in Xinjiang, to analyze the content of radionuclides and to estimate the internal exposure dose of residents caused by dietary intake. Methods The specific activity of 238U, 232Th, 226Ra, 40K and 137Cs of interest nuclides was measured, statistically analyzed by high purity germanium γ spectrometer, and the annual effective dose of these nuclides was estimated. Results No nuclide 238U was detected in food samples from 2018 to 2020. The average activity concentration and detection rate of other radionuclides were 232Th: 0.428 ± 0.038 Bq/kg (18.3%)、226Ra: 0.477 ± 0.063 Bq/kg (38%)、40K: 162 ± 7 Bq/kg (100%)、137Cs: 0.071 ± 0.011 Bq/kg (29.6%). The annual effective dose of residents due to food radionuclides was about 0.198 mSv. Conclusion The radioactivity level of food in the vicinity of a uranium mining mountain in Xinjiang is within the national standard limit, and the average annual effective dose caused by the diet of residents is consistent with the report of UNSCEAR in 2000. The content of artificial radionuclide 137Cs detected in food samples will not cause harm to the health of residents.
