Investigation and analysis of smoking behaviour of civil servants in Minhang District, Shanghai / 环境与职业医学

Background The tobacco epidemic as one of the most serious public health problems in the world contributes great harm to human health. It is urgent to develop tobacco control strategy. Civil servants' behaviors as a role model for society have a great influence on the rest of society. Thus, it is important to promote tobacco control program on helping civil servants to quit smoking. Objective To understand the smoking and second-hand smoking exposures status, the awareness of knowledge of tobacco hazards, and the attitudes to tobacco control policies of civil servants in Minhang District, Shanghai. Furthermore, to explore the related strategies and measures for tobacco control, to provide a basis for the development and revision of relevant intervention measures and policies. Methods A total of 20 government agencies with newly installed smoking-free programs from 10 subdistricts and towns in Minhang District, including Xinzhuang, Wujing, Maqiao, Qibao, Meilong, Hongqiao, Zhuanqiao, Jiangchuan, Gumei, and Xinhong were selected as study sites.A questionnaire survey was conducted to investigate all civil servants (n=801) of selected agencies. The questionnaire included general characteristics, smoking and second-hand smoking exposure status, knowledge of tobacco hazard, and attitudes to tobacco control policies. Results A total of 794 civil servants returned valid questionnaires. The awareness rate of tobacco hazards in the smoking group was lower than that in the non-smoking group (P<0.05). Relatively high smoking rates were reported in those being male (17.08%), age ≥51 years old (25.61%), divorced or widowed (12.50%), technical secondary school or below education level (22.81%), having more than 10 years of working years (11.57%), being willing to dissuade indoor smoking (24.54%), having no punishment or warning measures for violation of smoking regulations in workplaces (18.37%), and having no dedicated smoking spot at home (15.38%). The results of multiple logistic regression analysis showed that age 31-40 years old (OR=3.446, 95%CI: 1.236-9.609) and to avoid confronting indoor smoking (OR=3.686, 95%CI: 1.041-13.049) were risk factors for smoking in civil servants. Conclusion Civil servants aged 31-40 years old who deliberately avoid confronting indoor smoking behaviors are the key intervention population of smoking control in Minhang District, Shanghai.

Objective To investigate the association between ankle-brachial index (ABI) and serum uric acid (SUA) level in patients at high risk of cardiovascular diseases .Methods Three hundred and sixty-three patients with hypertension and diabetes mellitus (DM ) were divided into hyper-tension group (n=189) ,hypertension plus DM group (n=123) ,and DM group (n= 51) .Their ABI was assayed ,SUA level was measured ,and other risk factors for cardiovascular diseases were detected such as BMI ,systolic and diastolic pressure ,serum levels of TG ,TC ,HDL-C ,LDL-C and HbA1c .Association of SUA level and ABI with other clinical indexes was analyzed by partial cor-relation analysis .Results The systolic and diastolic pressure ,serum levels of TG ,HDL-C and HbA1c were significantly different in 3 groups (P<0 .05) .The ABI was significantly higher in hypertension group and DM group than in hypertension plus DM group ,and negatively related with SUA level after adjustment for hypertension and DM history ,age ,gender ,BMI ,serum levels of TG ,TC ,HDL-C ,LDL-C and HbA1c ,systolic and diastolic pressure (r= -0 .235 ,P=0 .012) . Conclusion ABI is associated with SUA level in patients at high risk of cardiovascular diseases .

Relationship between rs1057141 and rs1135216 polymorphisms of TAP1 gene and allergic rhinitis in Xinjiang Han people / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the association between transporter associated with antigen processing 1 (TAP1) rs1057141 and rs1135216 gene polymorphisms and predisposition to allergic rhinitis (AR) in Xinjiang Han people.@*METHOD@#A case control study was conducted. The region of the TAP1 * rs1057141 and rs1135216 was studied in 150 Xinjiang Han people with allergic rhinitis and 150 normal controls by using SNaPshot system, and these data were compared with other ethics groups in the world according to the NCBI gene bank.@*RESULT@#The genotypes distribution of the group were in the Hardy-Weinberg equilibrium(P>0.05). The frequencies of three genotypes(G/G, G/A, A/A) of TAP1 * rs1057141 were 4.00%, 30.00%, 66.00% in controls and 2.70%, 33.30%, 64.00% in AR groups , which showed no difference (P>0.05). The frequencies of three genotypes (G/G,G/A,A/A) of TAP1 * rs1135216 were 2.0%, 28.7%, 69.3% in controls and 1.30%, 27.30%, 71.40% in AR groups, which showed no difference either (P>0.05). According to the NCBI database, there was difference between Xinjiang Han people and other ethnics in the world.@*CONCLUSION@#Lacking association was found between the mutation of TAP1 * rs1057141, rs1135216 gene G allele and allergic rhinitis in the Xinjiang Han people. Maybe TAP1 * rs1057141, rs1135216 were not susceptibility genes to AR. And apparent differences existed in TAP1 gene polymorphisms between Xinjiang Han people and other ethnic groups in the world.

On the clinical application of spiral CT three-dimensional reconstruction of middle ear ossicles / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the CT virtual endoscopy (CTVE) shows the display method of the normal structure of the middle ear, and evaluation of middle ear disease, particularly in the value and significance of the connection status of the ossicular chain, established display ossicular chain and middle ear structure methods.@*METHOD@#Volume scanning with a spiral CT unit was performed in forty normal cases and thirty patients with suspected lesions of middle ear. Respectively, with Germany's Siemens (Siemens SOMATOM Sensation 16) spiral CT the Inner Ear scanner patients with axial scanning, reconstruction of the original image, the software selected Fly-through A, B, C the point approach CTVE imaging studies. Focus ossicular chain connection status, and chronic otitis media shown the results of surgery in exploratory image control.@*RESULT@#Normal group CTVE in the hammer bone, incus promontory, facial nerve, the lateral semicircular canal display rate was 100%; stapes, the two arch of the display rate in three display levels, respectively, to 57.5%, 70.0%, 97.5%; round window, oval window was 90.0%, 93.0%, 97.5%. Ossicular injury, displacement, interruption, deletion, deformity in cases of otitis media, trauma, temporal bone malformations.@*CONCLUSION@#CTVE link relations between the three ossicles (such as interrupt, etc.) have a certain advantage. By choosing the appropriate approach, CTVE has a considerable advantage in the ossicles and their connections, relations as well as pathological state. By comparing CTVE in three different display levels,the technique of CTVE is considered to be an advantageous supplement of tomography.

Study on the relationship between SNP of CD14 gene and allergic rhinitis in Xinjiang Uygurs and Hans / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#This study aimed to investigate the relationship between CD14 gene rs2569192(C/G), rs3138078 (--1359G/T) and allergic rhinitis (AR) in Xinjiang Uygur and Han populations as well as to determine characteristics of polymorphisms.@*METHOD@#A total of 300 AR and 300 healthy controls subjects were included. The frequencies of genotypes and alleles were detected as well as the levels of tIgE in different genotypes were compared.@*RESULT@#(1) The distribution of genotypes or alleles of CD14 gene rs2569192 (C/G), rs3138078 (--1359G/T) had no differences between the Xinjiang Uygurs and Hans (P > 0.05). The highest frequency of alleles was C, G. (2) The frequencies of genotypes and alleles were not different between the AR and control group in Uygur and Han (P > 0.05). The frequencies of genotypes and alleles of rs2569192 were different between the Uygur AR and Han AR group (P < 0.05). (3) The distribution of genotype frequencies and allele of rs 2569192 in the Xinjiang Uygur and Han population were quite different from Chinese Beijing Han populations, Japanese, European and African (P < 0.05). (4) The serum total IgE level in AR group was higher than that in healthy control group (P < 0.05).@*CONCLUSION@#(1) rs2569192 (C/G), rs3138078 (--1359G/T) polymorphisms were not different between the Chinese Xinjiang Uygur and Han population. The major allele were both C and G. rs2569192 of CD14 in Xinjiang populations was different from that in the other populations. (2) No relationship between rs2569192, rs3138078 and AR was found. (3) The serum total IgE level in AR group was higher than that in healthy control group. No relationship between CD14 two SNP and serum total IgE level was found.
