Abstract: Objective To understand the prevalence and influencing factors of major chronic diseases among Kirgiz residents in Aheqi County, Xinjiang, and to provide theoretical basis for the prevention and control of chronic diseases in this area. Methods　The data of residents in Aheqi County, Kizilsu Kirgiz Autonomous Prefecture, Xinjiang in 2020 for health checkup were selected, and the permanent residents of Kirgiz nationality aged ≥18 were selected as the survey objects, and the prevalence of major chronic diseases and their influencing factors were analyzed by Logistic regression model. Results　A total of 21 935 patients were enrolled, and 10 602 patients suffered from chronic diseases with a prevalence rate of 48.33%, including 4 929 cases of hypertension with a prevalence rate of 22.47%, 4 238 cases of obesity with a prevalence rate of 19.32%, 3 610 cases of dyslipidemia with a prevalence rate of 16.46%, 1 632 cases of anemia with a prevalence of 7.44%, and 1 236 cases of type 2 diabetes with a prevalence of 5.63%. The prevalence of hypertension, obesity, dyslipidemia and type 2 diabetes increased with age, while the prevalence of anemia decreased with age (P<0.01). The prevalence of hypertension dyslipidemia and type 2 diabetes was higher in males than in females, and the prevalence of obesity and anemia was higher in females than in males, with statistical significance (P<0.01). Logistic regression analysis showed that 30-<40 years old (OR=1.836, 95%CI: 1.565-2.034), 40-<50 years old (OR=2.916, 95%CI: 2.613-3.255), 50-<60 years old (OR=5.244, 95%CI: 4.651-5.913), 60 years old and above (OR=10.866, 95%CI: 9.533-12.385), government personnel (OR=1.789, 95%CI: 1.405~2.279), professional and technical personnel (OR=1.774, 95%CI:1.372-2.295), the office staff (OR=1.923, 95%CI: 1.418-2.607) occasional alcohol consumption (OR=1.157, 95%CI: 1.055-1.270) and occasional exercise (OR=1.498, 95%CI: 1.238-1.812) were risk factors for chronic disease. Conclusion　The prevalence of chronic diseases among residents in Aheqi County of Xinjiang is at a low level. Local health institutions have strengthened health education and publicity on multiple chronic diseases and the prevention and control of anemia among young and middle-aged women.

Objective To study the clinical char acteristics and outcome of two lymphoma patients mimicking Beh?et's disease. Methods Lymphoma was diagnosed in two patients mimicking Beh?et's disease referred to our Department in 2015. A search on published similar cases in Chinese database and the Pubmed was also performed and then analyzed. Results Eight patients were indentified in this pooled analysis, six of which were non-Hodgkin lymphoma (NHL). All of the eight cases presented with cutaneous lesion, seven cases with fever, seven cases with oral ulceration and six cases with orogenital ulceration, respectively. Ocular involvement was present in four of the eight cases, two were with a positive pathergy test. Among feverish patients, six were moderate or high fever, four were high fever, one was low-grade fever. Neutropenia was found in four patients, and lymphocytoponia in four of five patients with detailed data. All patients fulfilled the 2014 International Criteria for Beh?et's Disease (ICBD) with an average score of (5.8 ±1.5), ranging from 4 to 8.

OBJECTIVETo develop a RP-HPLC method for the determination of quercetin in UGT1A3 cDNA-transfected cells.

METHODSThe lysate of cells transfected with human recombinant uridine 5-diphosphate glucuronosyltransferases UGT1A3 cDNA was co-incubated with quercetin, the reaction was terminated with acetonitrile, and luteolin was used as internal standard. The determination was performed on a C(1) reversed phase column with a mobile phase of methanol-0.1% formic acid (V/V) at a flow rate of 1.0 ml/min. The gradient elution was as follows: 0 - 25 min (30:70-80:20, methanol:0.1% formic acid), > 25-25.5 min (80:20), >25.5-27 min (80:20-30:70), > 27-30 min (30:70). A UV-VIS detector was operated at 368 nm.

RESULTThe standard curve was linear over the concentration range of 5-200 μmol/L (r = 0.9999). The limit of detection was 1.25 μmol/L(S/N ≥ 3), and the limit of quantification was 5 μmol/L (S/N >10, RSD = 6.99%). The method afforded recoveries of 99.1%-103.5%, and precisions for inter- and intra-assay were < 2.5% and < 8%, respectively. In addition, kinetic analysis indicated that the K(m), V(max) and CL(int) (V(max)/K(m)) values for quercetin glucuronide were (62.95 ± 13.16) μ mol/L, (284.50 ± 24.35)nmol*min⁻¹*g⁻¹ and 4.52 ml*min⁻¹*g⁻¹, respectively.

CONCLUSIONThe method established is accurate and simple and suitable for the determination of quercetin in UGT1A3 cDNA-expressed cells.

OBJECTIVETo investigate the risk factors for hearing impairment in premature infants.

METHODSA total of 895 premature infants who were admitted to the neonatal intensive care unit from January to December 2010 were evaluated using distortion product otoacoustic emission to detect hearing impairment. The failure rates in initial screening and secondary screening were recorded. The risk factors for failure to pass hearing screenings were elucidate using multivariate logistic regression analysis.

RESULTSThe failure rate in initial screening was 38.4%, and the failure rate in secondary screening was 18.3%. In the auditory brainstem response test conducted at three months after birth, the failure rate was 22.2%. In premature infants with a gestational age of 28-29(+6) weeks, 60.5% did not pass the initial screening; 48.1% of the premature infants with a birth weight of 1 001-1 499  g failed the initial screening; 70.0% of the premature infants with a birth weight of ≤1 000  g failed the initial screening; 53.8% of the premature infants who had severe asphyxia failed the initial screening; 45.0% of the premature infants who used invasive ventilation failed the initial screening; 47.9% of the premature infants with a total bilirubin of ≥340 µmol/L failed the initial screening; 54.6% of the premature infants with septicemia failed the initial screenings. The multivariate logistic regression analysis revealed the following independent risk factors for failing the initial and secondary hearing screenings: gestational age, birth weight, hyperbilirubinemia and septicemia.

CONCLUSIONSPremature infants are susceptible to hearing impairment because they have immature organs and tissues and incomplete blood-brain barrier function and are sensitive to such factors as hyperbilirubinemia and infection. Early hearing screening and follow-up are necessary for premature infants to ensure timely interventions.

OBJECTIVEThe mechanism by which M.tuberculosis persists and survives in host macrophage is not fully understood, however, the M. tuberculosis chromosome-encoded TA loci perform functions possibly of signaling to these processes. To explore the biological functions of M. tuberculosis chromosome-encoded TA loci, the Rv1494 and Rv1495 genes of M.tuberculosis H37Rv strain were cloned and expressed.

METHODSThe hypothetical proteins Rv1494 and Rv1495 were bioinformatically analyzed by means of Bioedit software, Dnaman software and Pfam database. The complete open-reading frame sequences of Rv1494 and Rv1495 genes were amplified by PCR using M.tuberculosis H37Rv genomic DNA as the template, and the PCR products were cloned into prokaryotic expression vector pET32a(+), respectively. After induction of expressions in E.coli host strain BL21 (DE3), the recombinant proteins were purified and detected by Western blotting.

RESULTSAccording to bioinformatic analysis, the hypothetical proteins of Rv1494 and Rv1495 genes shared some homologies with mazEF family, one of E. coli chromosomal TA loci (homology at 26% and 29.5%). Sequence analysis showed that the inserted target genes and its reading frames were completely correct. The recombinant plasmids were induced with IPTG to effectively express the fusion proteins with relative molecular mass coincident with prediction. The specific positive signals were identified from the immunoblots.

CONCLUSIONFor the first time, the Rv1494 and Rv1495 genes of M.tuberculosis H37Rv strain were cloned and its prokaryotic expression vectors were constructed successfully in this experiment, which may facilitate further functional study of this mazEF-like gene pair.

The objective of this study was to explore the effect of amifostine (AMF) in treating patients with idiopathic thrombocytopenic purpura (ITP) and its adverse effects. 17 ITP patients (aged from 13 to 92, mean 65 years) were treated with AMF and their therapeutic regimen was following: 0.4 g AMF was dissolved in 100 ml physiological saline, the intravenous drop was performed at day and lasted 5 days per week, with interval 2 days, 4 weeks were considered as a course of treatment. The results showed that the normal counts of platelets were observed in 17 ITP patients after 1 course of treatment, and remained unchanged for 2 months following stop of therapy. In that time, no any drugs such as hormonal preparation, gamma-globulin, blood transfusion and so on were given in all treated patients, the main adverse effect of AMF was discomfort in digestive system that all patients could endure. Therefore, the patient's life quality was obviously improved. It is concluded that the AMF has been initially and successfully used to treat ITP patients with positive response, and may be considered as a safe-effective drug for treating old patients with ITP, but the long-term effect and pharmacological mechanism of this drug needs further evaluation.

Cell lines of Bcap37 and Bcap37/MDR1 (the high P-glycoprotein (P-gp) expressing cell line) were used as model to investigate the different accumulations of (E)-2-(4-(diethylamino methyl) benzylidene)-5,6-dimethoxy-2,3-dihydroinden-one (BYZX) in the two kinds of cells. It was authenticated that whether BYZX was the substrate of P-gp. Meanwhile, the inhibitive effects of BYZX on the P-gp were investigated by determining the fluorescence intensity of rhodamine 123 in the model cells, with and without BYZX. A reversed-phase high-performance liquid chromatography (RP-HPLC) method was used to determine the accumulations of BYZX in the two cells. The results showed that the amount of BYZX accumulation in Bcap37/MDR1 cells were as many as those in Bcap37 cells (P > 0.05), and the concentrations of BYZX accumulated in the Bcap37/MDR1 cells did not increase when co-incubated with P-gp inhibitor verapamil. Furthermore, different concentrations of BYZX also had no effects on the efflux of rhodamine 123 (P > 0.05). These results indicated that there were no interactions between BYZX and P-gp. BYZX will not be pumped out of the cells, and it also not inhibited the P-gp. It was the useful advantage for its absorption.
