Objective To evaluate the application of u lt rasound guided Mammotome minimally invasive biopsy system in the diagnosis and t reatment of breast mass. Methods B-ultrasound guided stereotac tic core breast biopsy using the Mammotome system was conducted in 221 breast ma sses of 132 patients. Unilateral solitary masses were found in 79 patients and u nilateral or bilateral multiple masses, in 53 patients. The mass was 0.5~5.2 cm (mean, 1.4 cm) in diameter. Of the 221 masses, 149 were clinically palpable. Results All the lesions were removed by using the Mammotome syste m. The stereotactic excisional biopsy was performed for a mean of 24 times, last ing a mean of 36 min (range, 10~40 min). No failed procedure occurred. All the m asses were pathologically confirmed as benign lesions in 129 patients and invasi ve ductal carcinomas in 3 patients (a modified radical mastectomy was then perfo rmed). Postoperatively, the incision scar was barely visible and no complication s happened except for mild subcutaneous hemorrhage in 10 patients. Conc lusions Use of B-ultrasound guided stereotactic core breast biopsy usin g the Mammotome system for the removal of benign breast lesions is convenient, e ffective, and minimally invasive.

Pleomorphic adenoma (PA) is the most common benign tumor of the salivary glands. Originating from the nasal cavity is very rare. This paper reports one case of pleomorphic adenoma of the inferior nasal turbinate to analyze the clinic characteristic of this disease. Although these tumors are rarely seen in everyday practice, one should consider this possibility as an uncommon aetiology when confronted with an intranasal mass.

Objective: To investigate the changing trends in the prevalence of health literacy among rural residents in Zhejiang Province from 2016 to 2021, so as to provide the evidence for formulating the health promotion strategy in rural areas. Methods: Rural residents' health literacy surveillance data were retrieved in Zhejiang Province from 2016 to 2021. The prevalence of health literacy was evaluated among rural residents according to the criteria defined by Chinese Center for Health Education, and standardized by Zhejiang Provincial population data captured from the national population census in China. The 6-year cumulative increase from 2016 to 2021 was estimated to investigate the changing trends in the prevalence of health literacy. Results: Totally 55 568 rural residents were monitored in Zhejiang Province from 2016 to 2021, including 26 893 men (48.40%) and 28 675 women (51.60%) and 32 156 residents at ages of 45 to 65 years (57.87%). The prevalence of health literacy was 18.00%, 21.52%, 25.53%, 27.54%, 30.85%, and 34.32% among rural residents in Zhejiang Province from 2016 to 2021, appearing a tendency towards a rise (χ2trend=661.376, P<0.001), and a 16.32% 6-year cumulative increase was seen. The prevalence of basic knowledge and concept, healthy lifestyle and behaviors and basic skills all appeared a tendency towards a rise (P<0.05), with 6-year cumulative increase rates of 24.48%, 11.08% and 8.11%, respectively. Among six categories of health issues, the prevalence of chronic disease prevention, scientific health outlook and health information literacy showed a tendency towards a rise year by year (P<0.05), with 6-year cumulative increase rates of 29.73%, 21.07% and 15.98%, respectively, and the prevalence of basic medical care, safety and first aid, and infectious disease prevention literacy appeared a fluctuation (P<0.05), with 6-year cumulative increase rates of 12.85%, 6.36% and -0.47%, respectively. The prevalence of health literacy appeared an overall tendency towards a rise in rural residents with different genders, age groups, educational levels and occupations (P<0.05), with a minor 6-year cumulative increase in residents at ages of 55 years and older and farmers, while a tendency towards a decline was seen among illiterate rural residents, with a 6-year cumulative rise of -3.16%. Conclusions The prevalence of health literacy appeared a tendency towards a rise among rural residents in Zhejiang Province from 2016 to 2021; however, the rate of increase reduced year by year. Health education and promotion should be enhanced targeting the elderly, individuals with low educational levels and farmers.

Objective: To investigate the prevalence of cigarette and electronic cigarette ( e-cigarette ) use among adults in Zhejiang Province, so as to provide insights into tobacco control. Methods : Thirty study sites were randomly sampled from Zhejiang Province in 2020 using a multi-stage stratified random sampling method, and permanent residents at ages of 15 to 69 years were selected as study subjects. A questionnaire was designed based on the questionnaire for the China Adult Tobacco Survey to collect subjects' demographic characteristics, cigarette and e-cigarette use, smoking cessation and exposure to secondhand smoke ( SHS ). The weighted prevalence of smoking, current smoking, current e-cigarette smoking, smoking cessation and exposure to SHS was estimated based on the Seventh National Population Census in 2020. Results : A total of 19 200 questionnaires were recovered, and 19 180 were valid, with an effective recovery rate of 99.90%. The respondents had a mean age of ( 50.30±12.90 ) years, with a male to female ratio of 1∶1.06 and an urban/rural population ratio of 1∶1.31. Among all the respondents, there were 6 033 smokers ( 31.45% ), 4 163 current smokers ( 21.70% ), 201 current e-cigarette users ( 1.05% ), 146 cigarette and e-cigarette dual users ( 0.76% ), 1 870 respondents quitting smoking ( 31.00% of smokers ) and 7 189 respondents with exposure to SHS ( 47.87% of non-smokers ). The weighted prevalence of smoking, current e-cigarette use, cigarette and e-cigarette dual uses, smoking cessation and exposure to SHS was 20.49%, 1.34%, 0.94%, 29.56% and 49.53% in Zhejiang Province, respectively, and the prevalence of current smoking, current e-cigarette use, cigarette and e-cigarette dual uses and exposure to SHS was 40.39%, 2.39%, 1.86% and 55.31% among males and 0.35%, 0.28%, <0.01% and 46.02% among females, respectively. The highest prevalence of current smoking was seen among respondents at ages of 55 to 64 years ( 24.24% ), while the highest prevalence of current e-cigarette use and cigarette and e-cigarette dual uses was seen in adults at ages of 25 to 34 years ( 2.18% and 1.58% ). Conclusions The prevalence of current e-cigarette use was higher among adults in Zhejiang Province in 2020 than the nationwide level in China. The prevalence of cigarette use was lower among adults in Zhejiang Province in 2020 than the nationwide level in China; however, improving the management of tobacco control in public places and the capacity building of smoking cessation services is still required to reduce the use of cigarettes and e-cigarettes.

Objective : To investigate the establishment of smoke-free environments in medical and healthcare institutions in Zhejiang Province, so as to provide the evidence for improving the implementation of the tobacco control policy in medical and healthcare institutions. Methods: Health administrative sectors and public health institutions at provincial, city and county levels, secondary and tertiary medical institutions, and community health service/township health centers in Zhejiang Province were enrolled. The status of institutional establishment of smoke-free environments was investigated through concealed photography and consulting medical service guides by the assigned the third-party professional investigation company in 2021. The layout of smoke-free environments and indoor smoking were assessed according to the Criteria for Scoring Smoking-free Medical and Healthcare Institutions. Results: Totally 547 medical and healthcare institutions were enrolled in this undercover investigation, including 102 health administrative sectors, 209 public health institutions, 146 secondary and tertiary medical institutions, and 90 community health service/township health centers. The gross mean scores of establishment of smoke-free environments were 83.41±12.19 among all medical and healthcare institutions, 82.02±10.73, 85.56±9.70 and 83.18±12.59 among province-, city- and county-level medical and healthcare institutions, respectively, and the gross mean scores of establishment of smoke-free environments were 82.60±12.27, 85.79±10.74, 80.89±13.85, 82.27±11.62 scores among health administrative sectors, public health institutions, secondary and tertiary medical institutions and community health service/township health centers, respectively. There were 315 institutions with no smoking signs at entrances (57.59%), 255 institutions posting no smoking signs ( 46.62% ), 245 institutions assigning two and more types of health education materials for tobacco control ( 44.79% ), 110 institutions with outdoor smoking areas ( 51.16% ), 66 secondary and tertiary medical institutions with smoking cessation clinics ( 45.20% ) and 354 institutions with carpet smoking bans in indoor places ( 64.72% ). Conclusions The overall establishment of smoke-free environments is satisfactory among medical and healthcare institutions in Zhejiang Province. Nevertheless, improving the coverage of no smoking signs and health education of tobacco control, promoting the standardized construction of smoking cessation clinics and establishing a long-action tobacco control mechanism are still needed.

Objective To investigate the use of free transplantation of peroneal artery perforator-based propeller to the repair of the front feet skin defect.Methods Thirteen cases with front foot skin defect patients repaired through transplation of propeller flap of the peroneal artery from January 2009 to September 2012.The wound range was 5 cm ×4 cm-11 cm × 14 cm.The propeller flap of the peroneal artery designed according to the position of the propeller of the peroneal artery in a leg.The wound of the leg were repaired through suture directly or transplantation of skin.Results All 13 cases of free propeller flap were survived,the wound healing goodly.One case with the postoperatie blood vessels were removed by the surgical exploration.The time of follow-up between 3 and 17 months(mean 9.4 months).The quality of free flap was good.The function of walk of the foot repaired were not significantly affect.The patients were satisfactory to the results.The wound of the leg healed well ; The leg had no obvious muscle cicatricial adhesion.According to the foot disease treatment effect evaluation standard (JOA) evaluation,the result for 77-100 points,an average of 85.5 points.Conclusion Using propeller flap of the peroneal artery to repair the skin defect of front feet with a little injury,the skin texture more close to the repaired area,it is a reasonable approach.

Objective:To describe the prevalence of tobacco use among college students in Zhejiang Province and analyze the influencing factors of second-hand smoke exposure on campus.Methods:In 2021, college students were selected from 9 colleges through stratified multi-stage cluster sampling from Zhejiang Province and surveyed using questionnaire. A total of 6 530 questionnaires were distributed and 6 035 were returned, with 6 030 valid questionnaires (96.48%). A descriptive analysis of the demography characteristics, cigarettes and electronic cigarettes (e-cigarettes) use, and second-hand smoke exposure of the subjects was carried out, and chi-square test was used for statistical analysis and multivariate logistic regression analysis was used to analyze influencing factors of second-hand smoke exposure on campus.Results:The current smoking rate and current use rate of e-cigarettes among college students were 3.70% and 1.56%, respectively, and the dual use rate of cigarettes and e-cigarettes was 1.16%. The exposure rate of second-hand smoke among college students on campus was 25.06%, while the exposure rate of second-hand smoke in off campus places was 32.35%. The awareness rates of smoking related diseases among college students were as follows: lung cancer (92.02%), heart disease (73.15%), stroke (72.87%), and impotence (64.08%). The awareness rate of second-hand smoke related diseases were as follows: lung cancer in adults (91.11%), heart disease in adults (78.91%), and lung disease in children (89.35%). The multivariate logistic regression analysis showed that seven factors (including gender, school type, major, grade, smoking ban regulations, smoking scenes, and knowledge about the health hazards of second-hand smoke) had a statistically significant impact on college students′ exposure to second-hand smoke at school [ OR=2.63, 0.67, 0.69, (0.39, 0.60, 0.68), 0.51, 1.74, 0.72] (all P<0.01). Conclusions:The use of cigarettes and e-cigarettes among college students in Zhejiang Province is not optimistic, especially the use rate of e-cigarettes is higher than adult. The status of second-hand smoke exposure among college students remains serious, with male students, non-medical students, students of special programs, and senior college students having more severe second-hand smoke exposure on campus, and students with high awareness of second-hand smoke exposure, less exposure to smoking scenes from media, from college with comprehensive smoke-free regulations are less exposed to second-hand smoke on campus.

Objective:To investigate the level of health literacy and its influencing factors among residents aged 15-69 years with different chronic disease in Zhejiang Province.Methods:In this cross-sectional study, a stratified multistage whole cluster random sampling method was used to select 19 200 permanent residents aged 15-69 years from 30 monitoring sites in Zhejiang Province from June to November 2022, and a household questionnaire survey was carried out with the National Health Literacy Monitoring Questionnaire for the Population. The content of the survey included socio-demographic characteristics, health-related factors and health literacy level. A total of 19 200 questionnaires were distributed and 19 051 were collected, of which 18 857 (98.98%) were valid. The χ2 test was used to compare the health literacy levels of residents with different chronic diseases, and logistic regression was used to analyze the influencing factors of the health literacy levels. Results:The health literacy level of residents aged 15-69 in Zhejiang Province in 2022 was 38.36%. Among them, the health literacy level of patients with multiple chronic diseases was much lower than those with single chronic disease and those without chronic disease (14.70% vs 25.37%, 42.21%) ( χ2=483.05, P<0.001). It was positively associated between having multiple chronic diseases and insufficient health literacy ( OR=1.26, 95% CI: 1.01-1.58); compared with those without chronic disease ( OR=1.00), patients with multiple chronic diseases were significantly more likely to have inadequate health literacy in basic knowledge and concepts ( OR=1.29, 95% CI: 1.03-1.63), health behaviors ( OR=1.24, 95% CI: 1.01-1.53), basic skills ( OR=1.37, 95% CI: 1.11-1.69), and health information literacy ( OR=1.27, 95% CI: 1.08-1.50). Conclusions:The number of chronic diseases is a key factor that affects the residents′ health literacy level, and people with multiple chronic diseases are often associated with a higher risk of inadequate health literacy.

Objective To investigate the severity of allogenic rejection after partial liver transplantation (PLTx) with different graft weight to recipient liver weight (GW/RLW).Methods The full-size liver transplantation (group A),GW/RLW ＞33％ PLTx (group B) and GW/RLW ＜ 30％ PLTx (group C) were set up using BN rats and Lewis rats as donors and recipients,respectively.All recipients were observed for 28 days.The Banff RAI grading,survival rate,jaundice and body weight recovery were evaluated to determine the severity of acute allogeneic rejection.Two PLTx groups,group B1 (GW/RLW＞33％) and group C1 (GW/RLW＜30％),were established to assess the mRNA level of IL-2,GranzymeB,Perforin and CD3 48 h and 7 days postoperatively.Additionally,the mRNA level of B7-H1,the ratio of Ki67 + hepatocytes and the liver enzymes were also assessed 7 days postoperatively.Results All recipients in group C died within 22 days postoperatively,presenting with severe lymphocytic infiltration and vascular endothelialitis.All recipients in group A and group B survived until the end of observation time.All recipients in group A survived and presented with a mild lymphocytic infiltration and rare vascular endothelialitis.Group B presented with moderate lymphocytic infiltration and moderate vascular endothelialitis.The Banff RAI grading in group C was significantly higher than that in group A and group B (P ＜ 0.05).In accordance with the result of histology and survival rate,group B and group C presented with earlier jaundice and lower body weight recovery than that of group A (P＜0.05).As compared with group B1,group C1 presented with higher mRNA levels of Perforin,GranzymeB,IL-2 and CD3,higher level of liver enzymes and heavier liver graft weights.Besides,the mRNA level of immunosuppresive molecule B7-H1 in group C1 was lower than that of group B1.However,there was no significant difference in the ratio of Ki67 + hepatocytes between group B1 and group C1.Conclusion The allogenic liver rejection may be enhanced by reducing the GW/RLW.
