Objective: To investigate the expression of MSI1 and HER2 in mammary Paget's disease, and the correlation between the expression levels of MSI1 and HER2 and the clinicopathologic characteristics and prognosis of the patients. Methods: Clinical data and paraffin-embedded specimens of 34 pairs of mammary Paget's disease and underlying breast cancer were collected at the Department of Pathology, Affiliated Lianyungang Oriental Hospital of Xuzhou Medical University from March 2011 to December 2019. Immunohistochemistry was used to detect the expression of MSI1 and HER2 in mammary Paget's disease and the accompanying breast cancer, and to analyze the correlation between the expression levels of MSI1 and HER2 and their clinicopathologic features, as well as their influence on prognosis. Results: In mammary Paget's disease, the positive rate of MSI1 was 91.2% (31/34) and the positive rate of HER2 was 88.2% (30/34); the expression of MSI1 and HER2 was positively correlated (P=0.001, r=0.530). The expression of MSI1 was positively correlated with menopausal status (r=0.372, P=0.030) and lymph node metastasis (r=0.450, P=0.008). HER2 expression was positively correlated with menopausal status (r=0.436, P=0.010), and negatively correlated with ER expression (r=-0.365, P=0.034). The co-expression of MSI1 and HER2 was positively correlated with age (r=0.347, P=0.044) and menopausal status (r=0.496, P=0.003), and negatively correlated with ER expression (r=-0.461, P=0.006). Conclusions: MSI1 and HER2 are highly expressed in mammary Paget's disease and their expression levels are positively correlated. The correlation analysis between clinicopathological features and prognosis suggests that both of them may be involved in the occurrence and development of mammary Paget's disease and are potential therapeutic targets for mammary Paget's disease.

OBJECTIVE:
To investigate the prevalence and subtype distribution of Blastocystis sp. in pigs in Anhui Province.
METHODS:
A total of 500 stool samples were collected from large-scale pig farms in Bozhou, Anqing, Chuzhou, Hefei, Fuyang, and Lu'an cities in Anhui Province from October to December 2015. Blastocystis was detected in pig stool samples using a PCR assay based on the small subunit ribosomal RNA (SSU rRNA) gene, and positive samples were subjected to sequencing and sequence analysis. Blastocystis subtypes were characterized in the online PubMLST database, and verified using phylogenetic tree created with the neighbor-joining algorithm in the Meta software.
RESULTS:
The prevalence of Blastocystis infection was 43.2% (216/500) in pigs in 6 cities of Anhui Province, and all pig farms were tested positive for Blastocystis. There was a region-specific prevalence rate of Blastocystis (17.2% to 50.0%) (χ2 = 26.084, P < 0.01), and there was a significant difference in the prevalence of Blastocystis sp. among nursery pigs (39.6%), preweaned pigs (19.1%), and growing pigs (62.3%) (χ2 = 74.951, P < 0.01). Both online inquiry and phylogenetic analysis revealed ST1, ST3, and ST5 subtypes in pigs, with ST5 as the predominant subtype.
CONCLUSIONS
The prevalence of Blastocystis sp. is high in pigs in Anhui Province, with three zoonotic subtypes identified, including ST1, ST3, and ST5.

Objective: To obtain experience and generate suggestions for reducing average hospital stays, optimizing perioperative management of patients with gastric cancer and improving utilization of medical resources by analyzing the factors influencing super-long hospital stays in patients undergoing radical gastrectomy in the age of enhanced recovery after surgery (ERAS). Methods: This was a case-control study. Inclusion criteria: (1) pathologically diagnosed gastric adenocarcinoma; (2) radical surgery for gastric cancer; and (3) complete clinicopathologic data. Exclusion criteria: (1) history of upper abdominal surgery; (2) presence of distant metastasis of gastric cancer or other ongoing neoplastic diseases; (3) concurrent chemoradiotherapy; and (4) preoperative gastric cancer-related complications such as obstruction or perforation. The study cohort comprised 285 eligible patients with hospital stays of ≥30 days (super-long hospital stay group). Using propensity score matching in a 1:1 ratio, age, sex, medical insurance, pTNM stage, and extent of surgical resection as matching factors, 285 patients with hospital stays of < 30 days during the same period were selected as the control group (non-long hospital stay group). The primary endpoint was relationship between pre-, intra-, and post-operative characteristics and super-long hospital stays. Clavien-Dindo grade was used to classify complications. Results: Univariate analysis showed that number of comorbidities, number of preoperative consultations, preoperative consultation, inter-departmental transference, operation time, open surgery, blood loss, intensive care unit time, presence of surgical or non-surgical complications, Clavien-Dindo grade of postoperative complications, and reoperation were associated with super-long hospital stays (all P<0.05). Inter-departmental transference (OR=4.876, 95% CI: 1.500-16.731, P<0.001), preoperative consultation time ≥ 3 d (OR=1.758, 95%CI: 1.036-2.733, P=0.034), postoperative surgery-related complications (OR = 6.618, 95%CI: 2.141-20.459, P=0.01), and higher grade of complications (Clavien-Dindo Grade I: OR = 7.176, 95%CI: 1.785-28.884, P<0.001; Clavien-Dindo Grade II: OR = 18.984, 95%CI: 6.286-57.312, P<0.001; Clavien-Dindo Grade III-IV: OR=7.546, 95%CI:1.495-37.952, P=0.014) were independent risk factors for super-long hospital stays. Conclusion: Optimizing preoperative management, enhancing perioperative management, and surgical quality control can reduce the risk of prolonging average hospital stay.

7.Study on the association between occupational noise exposure and cardiovascular diseases.
Chinese Journal of Industrial Hygiene and Occupational Diseases 2021;39(7):555-557
Occupational noise is one of the most common occupational hazards in the workplace. Long-term exposure to occupational noise could not only lead to the damage of the hearing system, but also may cause a certain impact on the cardiovascular system. Studies have shown that occupational noise exposure was positively associated with cardiovascular diseases, including hypertension, coronary heart disease and myocardial infarction. However, the results of studies on occupational noise exposure and stroke are still controversial. This paper reviews the relationship between occupational noise exposure and hypertension, coronary heart disease, stroke, myocardial infarction by summarizing the epidemiological data of domestic and foreign population in recent years. Our study could provide evidence for the design and implementation of well-designed epidemiological and mechanism studies, and the recognition of the role of occupational noise exposure in the occurrence and development of cardiovascular diseases, so as to better protect workers' health.

Objective: To study the willingness and influence factors related to "centralized slaughtering, fresh poultry listing and marketing" strategy, among the household chefs, and provide reference for government to adjust and optimize the strategy on avian influenza prevention. Methods: According to the geographical characteristics and regional functions, 6 'monitoring stations' were selected from 12 residential districts of Guangzhou, respectively. Another 21 meat markets which selling live poultry, were selected in each station and 5 household chefs of each market were invited to attend a face to face interview. Basic information, personal cognitive, willingness and influencing factors to the policy were under study. Univariate and multivariate logistic regression methods were used. Results: A total of 664 household chefs underwent the survey and results showed that the rate of support to the "centralized slaughtering, fresh poultry listing and marketing" strategy was 44.6% (296/664). Results from the multi-factor logistic regression showed that those household chefs who were males (OR=1.618, 95% CI: 1.156-2.264, P=0.005), having received higher education (OR=1.814, 95% CI: 1.296-2.539, P=0.001), or believing that the existence of live poultry stalls was related to the transmission of avian influenza (OR=1.918, 95% CI: 1.341-2.743, P<0.001) were factors at higher risk. These household chefs also intended to avoid the use of live poultry stalls (OR=1.666, 95%CI: 1.203-2.309, P=0.002) and accept the "centralized slaughtering, fresh poultry listing and marketing" strategy. Conclusion: Detailed study on this subject and, setting up pilot project in some areas as well as prioritizing the education programs for household chefs seemed helpful to the implementation of the 'freezing-fresh poultry' policy.

Objective: To investigate the prevalence of physical activity and its influencing factors in rural residents in Shanxi and Chongqing. Methods: In four counties (districts) of Shanxi and Chongqing, local residents aged ≥18 who lived there for more than one year and had no plan to migrate to other areas in 2 years were surveyed through face to face questionnaire interviews to collect the information about their daily physical activity time, sedentary time, related knowledge and attitude, and others. Results: The physical inactivity rate of the residents was 14.9%, and 88.7% of residents never took daily physical activity. The average sedentary time was (3.91±2.06) hours. The results of multivariate analysis showed that education level, per capita monthly income and activity degree were the factors influencing physical inactivity. Conclusion: The proportion of people who never took daily physical activity in the survey area was higher than the average level in rural areas in China, so measures should be taken to improve the overall rate of physical activity. For people who have exercise willingness, but have no practice, and those who have already increased their physical activities, targeted guidance is needed on the basis of strengthened health education.
