A survey on smoking status and risk factors was conducted among 3373 residents in two districts of Shen yang city during November 2008 and September 2009 ; the pulmonary function tests were also performed for all subjects.A logistical regression model was used to evaluate the risk factors of smoking,and the knowledge about diseases caused by smoking was evaluated by chi-square test.The overall smoking rate was 50.7％ ( 1710/3373 ) ; 86.8％ (1458/1680) for males a(un)14.9％ (252/1693)for females.The risk factors of smoking ( P ＜ 0.05 ) in order of OR value were as follows:drinking,work environment and underlying diseases ; the protective factors were:female,educational level,overweight ( BMI ≥ 24) and old age.The survey on knowledge of smoking-related disease was conducted in 2478 residents including 815 smokers and 1663 non-smokers. The awareness levels about whether smoking can cause COPD,asthma,birth defects,malignant tumor,abortion,growth retardation,fetal death and myocardial infarction were significantly different between smokers and non-smokers.

Objective To investigate the effect of pelvic floor stabilized structure preservation (PPSS) during robot-assisted laparoscopic radical prostatectomy (RARP)on postoperative continence recovery.Methods From October 2017 to April 2018,86 patients with prostatic cancer who underwent traditional RARP and RARP plus PPSS were included.There were 31 patients in non-PPSS group and 55 patients in PPSS group.In non-PPSS group,patients age was (68.48 ± 7.79) years old,BMI was (24.79 ± 3.05) kg/m2,median prostate volume was 63.54 (53.00-99.36) cm3,clinic T-stage T1-T2,T3,T4 accounted for 49.39％,22.58％,6.45％ and ISUP grade 1,2,3,4,5 accounted for 22.58％,22.81％,12.90％,12.90％,19.35％ respectively.In PPSS group,patients age was (69.53 ± 6.81)years old,BMI was (23.95 ± 3.03) kg/m2,median prostate volume was 73.39 (54.88-94.23) cm3,clinic T-stage T1-T2,T3,T4 accounted for 72.73％,7.27％,3.64％ and ISUP grade 1,2,3,4,5 accounted for 21.82％,18.18％,23.64％,18.18％,10.91％ respectively.The preoperative PSA,BMI,clinical T-stage,ISUP grade,and postoperative hospital days had no significant differences (P ＞ 0.05)between the two groups.Both groups were operated via transperitoneal approach.In the non PPSS group,endo-pelvic fascia and pubic prostate ligament was cut,and dorsal vessel complex was ligated.In PPSS group,the partial endo-pelvic fascia was bluntly pushed to the pelvic wall to preserve tendon arch,and pubic prostate ligament also was preserved without suturing and ligating dorsal vascular complex.The catheter was removed 7 d after RARP.The continence recovery were compared between the two groups,including pad number on the day of I,7,14,30,90 and ICI-Q-SF scores on the day of 30 and 90 after catheter removal.Results There was no significant difference in pad numbers used between the two groups on the day of 1,7,14,30 after catheter removal.On the 90th day,the proportions of using pad ≥4 in PPSS group were significantly lower than those in non-PPSS group (1.89％ vs.20.69％,P =0.004).No significant difference was found in ICI-Q-SF scores on the 30th and 90th day between the two groups.Univariate analysis showed that PPSS group used less pads than non-PPSS group on the 90th day [OR =0.07(95％ CI 0.01-0.65),P =0.019];T3 patients used more pads than T1-T2 patients [OR =9.19 (95％ CI 1.32-63.87),P =0.025].After adjusting for age,ISUP grading,T staging,and PSA,multivariate regression analysis showed that the risk of using pad ≥ 4 in PPSS group compared with non-PPSS group was 0.46,0.34,0.27,0.25,and 0.03 on the day of 1,7,14,30 and 90 after catheter removal,respectively.The PPSS approach didn't increase the risk of positive surgical margin.Conclusions Preservation of pelvic stabilized structure in RARP is very efficient in term of continence rate after RARP,and it does not increase the risk of positive surgical margin.

Objective:To explore the expressions of long non-coding RNA LINC00673 and ISG15 protein in pancreatic cancer and their clinical significances.Methods:The clinical data of 57 patients diagnosed as pancreatic ductal carcinoma (PDAC) at the Affiliated Cancer Hospital of Xiangya Medical College of Central South University from January 2014 to December 2018 were retrospectively analyzed. The relative expressions of LINC00673 in pancreatic cancer tissues and paracancerous normal tissues (within 3 cm from the edge of cancer tissues) were examined by using quantificational reverse transcription-polymerase chain reaction (qRT-PCR). The ISG15 protein expressions in pancreatic cancer tissues and paracancerous normal tissues were examined by using immunohistochemistry. The difference in LINC00673 expression between ISG15 protein positive and negative patients was compared. The correlation between LINC00673 and ISG15 protein expressions in pancreatic cancer was analyzed by Spearman rank correlation analysis. Moreover, the correlations of LINC00673 and ISG15 protein expressions with clinical stage and pathological classification of pancreatic cancer patients were analyzed.Results:The positive expression of ISG15 protein in pancreatic cancer tissues was 40.4% (23/57), which was higher than that in paracancerous normal tissues [15.8% (9/57)] ( χ2 = 7.90, P = 0.004), and the relative expression of LINC00673 in pancreatic cancer tissues was 0.99±0.36, which was lower than that in paracancerous normal tissues (1.26±0.41) ( t = 4.80, P < 0.001). For 23 (40.4%) ISG15-positive patients and 34 (59.7%) ISG15-negative patients, the relative expression of LINC00673 was 0.77±0.46 and 0.45±0.27 ( P < 0.001). Spearman analysis showed that there was a correlation between LINC00673 and ISG15 protein expressions ( ρ = -0.429, P = 0.001). The relative expression of LINC00673 decreased in patients with low differentiated or undifferentiated tumor, vascular invasion and lymph node metastasis (all P < 0.05), but there was no correlation between LINC00673 expression and patients' age, tumor site, preoperative CA199 level, and TNM stage (all P > 0.05); ISG15 protein expression increased in patients with low differentiated or undifferentiated tumor, TNM stage Ⅲ-Ⅳ, vascular invasion and lymph node metastasis (all P < 0.05), but there was no correlation between ISG15 protein expression and patients' gender, age, tumor site, and preoperative CA199 level (all P > 0.05). Conclusions:The expression of LINC00673 in pancreatic cancer is related to vascular invasion, tumor differentiation degree and lymph node metastasis, and the expression of ISG15 in pancreatic cancer is related to vascular invasion, tumor differentiation degree, lymph node metastasis and TNM stage. The combined detection of LINC00673 and ISG15 protein could be a valuable prognostic indicator for pancreatic cancer. The therapies targeting LINC00673 and ISG15 protein signaling pathways are expected to be a potential option for immunotherapy of pancreatic cancer.

Background Lifestyle intervention or dietary modification has been the cornerstone of primary prevention and management of type 2 diabetes (T2D). Objective To investigate the associations of plant foods intake with the risk of incident T2D. Methods Based on a general population cohort, the Shanghai Suburban Adult Cohort and Biobank (SSACB), dietary data were collected for each participant in Songjiang District of Shanghai at enrollment with a validated Food Frequency Questionnaire (FFQ), and plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI) were calculated. Incident T2D cases were identified according to physician diagnosis (fasting blood glucose ≥7.0 mmol·L⁻¹, or 2 h value during a 75-g oral glucose tolerance test ≥11.1 mmol·L⁻¹, or glycosylated hemoglobin ≥6.5%, or with typical symptoms of hyperglycemia or hyperglycemic crisis, accompanied by a random plasma glucose ≥11.1 mmol·L⁻¹) or medication records, obtained from the electronic information system for residents' medical insurance. Multivariable-adjusted Cox proportional hazards models and restricted cubic splines were used to evaluate the associations of foods from different sources with the risk of incident T2D. Results A total of 29016 participants [age at baseline (55.3±11.6) years] with a median follow-up duration of 5.688 years until 21 September 2022 were included. Plant foods (unprocessed) intake was associated with a decreased risk of incident T2D [HR (95%CI): 0.983 (0.969, 0.998)]. In comparison with participants in the highest quartile (≥859.3 g) of plant foods daily intake, the risk of incident T2D for those in the lowest quartile (<500.9 g) was higher [HR (95%CI): 1.250 (1.012, 1.544)]. No significant associations of animal foods [HR (95%CI): 1.006 (0.987, 1.026)] and processed foods [HR (95%CI): 0.978 (0.944, 1.014)] intakes were found with the risk of incident T2D. Replacing 50 g animal foods [HR (95%CI): 0.982 (0.968, 0.996)] or processed foods [HR (95%CI): 0.983 (0.969, 0.998)] with 50 g plant foods was associated with significantly decreased risks of incident T2D. Additionally, non-linear associations of PDI (P_nonlinear=0.023) and hPDI (P_nonlinear=0.016) with the risk of incident T2D were found in the SSACB. Conclusion Plant foods intake, especially healthful plant foods intake, is significantly associated with a decreased risk of incident T2D.
