Influence of individualism and collectivism on self-reported health of retired military cadres / 第二军医大学学报

Objective To investigate the effects of individualism and collectivism on the self-reported health of military retired cadres. Methods The Chinese version of the European quality life-5 dimensions (EQ-5D), the individualism-collectivism scale, and the Memorial University of Newfoundland Scale of Happiness were used to survey 112 retired military cadres from military cadre sanatoria in Shanghai, Suzhou and so on. The data were analyzed by SPSS 22.0 software. Results A total of 112 questionnaires were sent out, and 71 valid questionnaires were collected, with an effective rate of 63.39%. The scores of individualism and collectivism of retired military cadres (n＝71) were lower than those of college students (n＝403), the difference was statistically significant (t＝－4.81 and －7.95, both P＜0.01). Correlation analysis results showed that there was no significant correlation between gender, age, education level, marital status, children's number, residence status and self-reported health status, subjective well-being, individualism and collectivism (all P＞0.05); subjective well-being, individualism and self-reported health were positively correlated (r＝0.44, P＜0.01; r＝0.29, P＜0.05), collectivism and self-reported health were not significantly correlated (r＝0.19, P＞0.05), and individualism and collectivism were positively correlated (r＝0.67, P＜0.01). Hierarchical multiple regression showed that the inclusion of individualism and collectivism improved the model interpretation rate (ΔR2＝0.08, F＝3.41, P＜0.05) after controlling subjective well-being. Individualism could predict health status (β＝0.34, P＜0.05), while collectivism could not (β＝－0.09, P＝0.55). Conclusion Individualistic cultural orientation is the main factor that affects the health of retired military cadres, while collectivist cultural orientation has no obvious effect.

Objective To investigate the pshcyological status and influencing factors of patients with acute pancreatitis. Methods Acute pancreatitis patients admitted in Changhai Affiliated Hospital of Navy Medical University from December 2018 to February 2019 were enrolled, and 120 patients were selected using random number table method. Self-made general questionnaire, self-rating depressing scale, self-rating anxiety scale and coping style questionnaire were used for investigation and patients′ psychological status was evaluated. Results In this survey, 109 questionnaires were collected and eligible for final analysis. The incidence of depression in patients with acute pancreatitis was 44. 0％, and the incidence of anxiety was 20. 2％. Male patients had significantly lower anxiety and depression than women. The levels of anxiety and depression in the 31-50 age group were significantly lower than those in other age groups. The level of anxiety in patients with pancreatitis with children was significantly lower than in patients without children. The coping style of "solving problem" was significantly negatively correlated with depression and anxiety level. The"self-blame" coping style was significantly positively correlated with depression and anxiety level. The"rationalized"coping style was positively correlated with the level of depression. Conclusions The mental health status of patients with acute pancreatitis was not optimistic. Different coping styles were important factors affecting the level of anxiety and depression.

Comprehension, memory and job performance between submariners and off-shore staffs: A comparative study / 第二军医大学学报

Objective: To investigate the effects of submarine environment on the comprehension, memory and job performance of submariners through a comparative study. Methods: A cluster sampling method was used to select 141 submarine crew members from a submarine detachment, and 159 off-shore crew members from a submarine base were taken as the controls. The comprehension capability was examined with comprehension testing subscale of Wechsler adult intelligence scale-Chinese revised in the two groups, and the memory capability was examined with picture arrangement subscale of Wechsler memory scale-Chinese revised. The job performance was evaluated by hand coordination tester and finger flexity tester, and the results were compared between the two groups. Results: Comprehension test showed that the comprehension ability of submariners with a more than 5 years service experience was significantly lower than that of off-shore counterparts (t=4.67, P<0.01). In hand coordination test, the out track times were significantly more in submariners with a 3-5 and more than 5 years service experience than those in off-shore counterparts (Z= - 2.20, P<0.05; Z= - 2.21, P<0.05). In finger flexity test, the out track times was significantly more in submariners with a 3-5 and more than 5 years service experience than those in off-shore counterparts (Z= - 3.08, P<0.01; Z= - 4.52, P<0.01). Conclusion: Comprehension ability and job performance of submariners are lower than those of off-shore counterparts. Comprehension ability of submariners with a more than 5 years service experience is worse than that of off-shore counterparts. Job performance of submariners with a 3-5 or more than 5 years service experience is worse than that of off-shore counterpart. The submarine environment has no obvious influence on memory of submariners.

Risk assessment of dietary exposure for organophosphates pesticides residues in some vegetables in Shaanxi Province / 预防医学

Objective To assess the dietary risk of organophosphates pesticides residues in some vegetables in Shaanxi Province. Methods The monitoring data of organophosphorus pesticides in vegetables from 2012 to 2016 were derived from Shaanxi Province Food Contamination Monitoring Network. The exposure of organophosphorus to vegetables by using exposure risk index (ERI) , dietary exposure risk index (RI) and dietary exposure risk assessment. Results Exposed risk index (ERI) of organophosphorus in some vegetables in Shaanxi Province ranged from 1.25E-06 to 1.87E-01, and among them, the highest ERI of clozaptid in garlic was 1.87E-01, followed by onion. In some vegetables, the highest exposure to organophosphorus was isocarbophos of fresh beans with an exposure of 4.27E-02 μg / (kg body weight · day) and the lowest dietary exposure was bulbs, and stems and fresh beans were 2.00E-04μg / (kg body weight·day) . The exposure of organophosphorus to all kinds of vegetables was less than their respective daily allowable intake (ADI) . The risk of dietary exposure to organic- phosphorus in vegetables was 187％ and greater than 100％ for the risk index (RI) of lettuce, and RI for all other vegetables was <100％. Conclusion The dietary exposure and risk index of organophosphates pesticides in some vegetables in Shaanxi Province was safe, and more attention should be paid to dimethoate and isazofos.

A comparative study of attention focusing between submariners and off-shore staffs / 第二军医大学学报

Objective To investigate the effects of submarine environment on the ability of attention focusing and distribution of submariners through a comparative study. Methods To measure simple reaction time, complex reaction time, correct times of reaction, the time on targets as well as the times out of track with attention focus measuring instrument (EP701C) and attention distribution measuring instrument(EP708A). Results In the attention focusing test, the times out of track of target was significantly more in submariners with a 3-5 years service experience compared with their off-shore counterparts(t=2.03,P<0.05). The time on targets was significantly shorter in submariners with a more than 5 years service experience compared with their off-shore counterparts(t=2.27,P<0.05), and the times out of track of target was significantly more in submariners (t=2.12,P<0.05). In the attention distribution test, the correct times of reaction in submariners with 3-5 years service was significantly less than their off-shore counterparts(Z=7.03,P<0.01), and the same was also true for those with a more than 5 years service experience(Z=7.74,P<0.01). Conclusion Our findings indicate that the attention abilities of submariners are lower than those of off-shore staffs, and 3-5 year service period is the important time for impairment of attention ability among submariners.

Influence of Inner Circular Sealing Area Impression Method on the Retention of Complete Dentures

The aims of the present study were to describe an impression method of "inner circular sealing area" and to evaluate the effect of the method on retention, aesthetics and comfort of complete dentures, which lack labial base for patients with maxillary protrusions. Three patients were subjected to the experiment, and two sets of complete maxillary dentures were made for each patient; the first set was made without labial base via an inner circular sealing area method (experimental group) and the second had an intact base that was made with conventional methods (control group). Retention force tests were implemented with a tensile strength assessment device to assess the retention and a visual analogue scale (VAS) was used to evaluate the comfort between the two groups. Results showed larger retention force, better aesthetics and more comfort in the experimental group. The improved two-step impression method formed an inner circular sealing area that prevented damage to the peripheral border seal effect of the denture caused by incomplete bases and obtained better denture retention.

O objetivo deste caso foi descrever um método de impressão por "área de selamento circular interno" e avaliar o efeito deste método na retenção, estética e conforto de próteses totais sem base labial para pacientes com protrusão maxilar. Três pacientes foram objeto desta experiência e foram feitas duas próteses maxilares completas para cada um deles; a primeira foi elaborada sem base labial pelo método de área de selamento circular interno (grupo experimental) e a outra teve uma base feita pelo método convencional (grupo controle). Foram realizados testes de retenção com estudo de tensão para avaliar a retenção e para avaliação do conforto dos dois grupos, foi empregada a escala analógica visual (EAV). Os resultados demonstraram que o grupo experimental apresentou força de retenção maior, estética melhor e mais conforto. O método modificado de impressão em duas etapas formou uma área de selamento circular interno que evitou danos ao selamento periférico causados por bases incompletas e obteve melhor retenção da prótese.

Differentially expressed genes and signalling pathways are involved in mouse osteoblast-like MC3T3-E1 cells exposed to 17-β estradiol / 国际口腔科学杂志·英文版

Oestrogen is essential for maintaining bone mass, and it has been demonstrated to induce osteoblast proliferation and bone formation. In this study, complementary DNA (cDNA) microarrays were used to identify and study the expression of novel genes that may be involved in MC3T3-E1 cells' response to 17-β estradiol. MC3T3-E1 cells were inoculated in minimum essential media alpha (α-MEM) cell culture supplemented with 17-β estradiol at different concentrations and for different time periods. MC3T3-E1 cells treated with 10⁻⁸ mol⋅L⁻¹ 17-β estradiol for 5 days exhibited the highest proliferation and alkaline phosphatase (ALP) activity; thus, this group was chosen for microarray analysis. The harvested RNA was used for microarray hybridisation and subsequent real-time reverse transcription polymerase chain reaction (RT-PCR) to validate the expression levels for selected genes. The microarray results were analysed using both functional and pathway analysis. In this study, microarray analysis detected 5403 differentially expressed genes, of which 1996 genes were upregulated and 3407 genes were downregulated, 1553 different functional classifications were identified by gene ontology (GO) analysis and 53 different pathways were involved based on pathway analysis. Among the differentially expressed genes, a portion not previously reported to be associated with the osteoblast response to oestrogen was identified. These findings clearly demonstrate that the expression of genes related to osteoblast proliferation, cell differentiation, collagens and transforming growth factor beta (TGF-β)-related cytokines increases, while the expression of genes related to apoptosis and osteoclast differentiation decreases, following the exposure of MC3T3-E1 cells to α-MEM supplemented with 17-β estradiol. Microarray analysis with functional gene classification is critical for a complete understanding of complementary intracellular processes. This microarray analysis provides large-scale gene expression data that require further confirmatory studies.

Effect of thoracic duct ligation during transthoracic esophagectomy on the prevention of post-operative chylothorax in different tumor locations / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of thoracic duct ligation during transthoracic esophagectomy on preventing post-operative chylothorax in different tumor locations.</p><p><b>METHODS</b>Between March 2003 and June 2007, 243 patients with thoracic esophageal carcinoma underwent esophageal resection in our hospital. All the cases were divided into five groups according to tumor localization, including cervical, upper middle, middle, lower middle and lower sections. Each was then subdivided into 2 groups: with and without intraoperative thoracic duct ligation. Statistical analysis was carried out to evaluate the relevance between ligation and non-ligation of the thoracic duct during esophagectomy and the incidence of post-operative chylothorax.</p><p><b>RESULTS</b>A total of 8 cases of post-operative chylothorax was recorded and the incidence was 3.3%. Incidence with respect to tumor location was as follows: cervical section: ligation subgroup 3 cases and non-ligation subgroup 5 cases; upper middle section: no one for both ligation and non-ligation subgroups; middle section: ligation subgroup 0/26 and non-ligation subgroup 1/28 (3.6%); lower middle section: ligation subgroup 1/39 (2.6%) and non-ligation subgroup 1/35 (2.9%); lower section: ligation subgroup 1/37 (2.7%) and non-ligation subgroup 2/44 (4.5%). Logistic regression analysis revealed no significant difference between ligation and non-ligation subgroup in the prevention of post-operative chylothorax (P>0.05).</p><p><b>CONCLUSION</b>Thoracic duct ligation as preventive measure can not decrease the incidence of chylothorax secondary to esophagectomy.</p>
