Objective:
To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes.
Methods:
The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model.
Results:
A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915).
Conclusion
The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

OBJECTIVE:To provide reference for rational use of Shexiang tongxin dripping pills in clinic. METHODS:In retrospective study,the utilization of Shexiang tongxin dripping pills in outpatients and inpatients of our hospital during Jan. 2014-May 2015 was analyzed statistically in terms of gender,age,department,irrational drug use,ADR and DUI,etc. RE-SULTS:There were 719 outpatient prescriptions and 281 inpatient medical orders. The female was more than male with ratio of 1.42:1. Most patients aged 80-89 year-old(35.4%). Shexiang tongxin dripping pills were mostly used in cardiovascular medicine de-partment(760 pieces/copies,76.0%). There were 72 prescriptions/medical orders that did not conform to the indications(7.2%), and 7 prescriptions/medical orders for overdose use(0.7%). No obvious ADR was found. DUI of Shexiang tongxin dripping pills was 1.007. CONCLUSIONS:Although the clinical use of Shexiang tongxin dripping pills in our hospital is basically rational,there still are some nonstandard uses,which should be taken seriously. In order to reduce ADR,the clinical use of Shexiang tongxin dripping pills should be strictly in accordance with the drug instructions and should emphasize the syndrome differentiation based on treatment.

Objective The sensitivity and specificity of 18 FDG PET/CT are poor in the diagnosis of gastric cancer .Gastric signet ring cell carcinoma and Mucinous gastric carcinoma is known to have low fluorodeoxyglucose (18FDG) uptake,but not known for poorly differentiated gastric adenocarcinoma .This study was to investigate the value of 18 FDG PET/CT in the diagnosis of poorly differ-entiated gastric adenocarcinoma . Methods We retrospectively analyzed the results of 18 FDG PET/CT of 34 cases of histologically confirmed poorly differentiated gastric adenocarcinoma .We recorded the volume , location , and gastric wall invasion depth , and maxi-mum standardized uptake value ( SUVmax) of the tumors and analyzed the relationship of 18 FDG uptake with the clinicopathologic pa-rameters. Results By 18 FDG-PET/CT, poorly differentiated gastric adenocarcinoma was diagnosed in only 67.6% of the patients (23/34).SUVmax was found to be significantly correlated with age , gastric wall invasion, and tumor size (P<0.05), but not with gender , tumor location , tumor pathologic subtype , lymph node metastasis , and distant metastasis ( P>0 .05 ) .Logistic regression a-nalysis showed the tumor size to be the sole factor influencing the 18 FDG uptake of poorly differentiated gastric adenocarcinoma ( OR=0.37, 95%CI 0.154-0.920, P=0.03). Conclusion The di-agnostic value of 18 FDG-PET/CT is but limited for poorly differentia-ted gastric adenocarcinoma , and attention should be paid to its false-negative results .

Objective:
To explore the effects of short-term exposure to four air pollutants, namely fine particulate matter (PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2) and ozone (O3), on death and years of life lost (YLL).
Methods:
Air pollutants and meteorological data in Jindong District and Wucheng District of Jinhua City, Zhejiang Province from 2014 to 2021 were collected through Jinhua Environmental Monitoring Center and Jinhua Meteorological Bureau. Death data of residents during the same period was collected through Zhejiang Province Chronic Disease Monitoring Information Management System. The effects of short-term exposure to four air pollutants on death and YLL were analyzed using a generalized additive model.
Results:
The results of single-pollutant model analysis showed that the lagged effect of short-term exposure to PM2.5 on death and YLL was the largest at cumulative lags of 2 days, with effect size of 1.064% (95%CI: 0.450%-1.682%) and 2.084 (95%CI: 1.003-3.165) person-years, respectively; the effect of short-term exposure to SO2 on YLL was the largest on the same day, with an effect size of 2.432 (95%CI: 0.610-4.254) person-years; short-term exposure to NO2 and O3 had no statistically significant effects on death and YLL (both P>0.05). The results of gender- and age-stratified analysis showed that short-term exposure to PM2.5 had significant lagged effects on death and YLL among females and residents aged 65 years and above at cumulative lags of 2 days; short-term exposure to SO2 had significant effects on YLL among females and residents aged 65 years and above on the same day (both P<0.05). The results of dual-pollutant model analysis showed that after the inclusion of NO2 in PM2.5 and SO2, the effects on death and YLL were statistically significant, with the effect size being higher compared to the single-pollutant model; after the inclusion of SO2 or O3 in PM2.5, the effects on death and YLL were statistically significant, with the effect size being lower compared to the single-pollutant model (all P<0.05).
Conclusion
Short-term exposure to PM2.5 may increase the risk of death and YLL, and short-term exposure to SO2 may increase the risk of YLL among residents, with more significant impacts on female and residents aged 65 years and above.

Objective:
To construct air quality health index (AQHI) in Jinhua City, Zhejiang Province based on the exposure-response relationship between air pollutants and years of life lost (YLL), and evaluate the health risk associated with air quality.
Methods:
Air pollutants and meteorological data in Jindong District and Wucheng District of Jinhua City from 2014 to 2021 were collected through Jinhua Environmental Monitoring Center and Jinhua Meteorological Bureau. Non-accidental death data of residents during the same period was collected through Zhejiang Chronic Disease Monitoring Information Management System. The exposure-response relationship between major air pollutants and YLL was analyzed using a generalized additive model (GAM), and major pollutants were screened for calculating AQHI. The exposure-response relationship between AQHI and YLL was analyzed using GAM.
Results:
The results of single-pollutant model analysis showed that the lagged effect of PM2.5 on YLL was the largest at lag of 1 day, and the effect of SO2 on YLL was the largest on the same day. The results of dual-pollutant model analysis showed that the impact of PM2.5 on YLL was statistically significant when other pollutants were included at a lag of 1 day, and the impact of SO2 on YLL was statistically significant when NO2 was included on the same day (all P<0.05). The average daily mass concentration of O3 exceeded the standard by a relatively high rate of 42.27% from 2014 to 2021. Based on the analysis results of single-pollutant and two-pollutant models, excessive pollutant condition and relevant research findings, PM2.5, SO2, NO2 and O3 were selected as the major pollutants for calculating the AQHI. The median AQHI value of 1.40 (interquartile range, 1.13) from 2014 to 2021. According to the AQHI classification standard, 94.55% was the time was at low risk, and 4.93% of the time was at medium risk. With an increase in AQHI by one interquartile range, the YLL among the entire population, males, females, <65-year-old and ≥65-year-old populations would increase 6.21, 3.26, 6.46, 4.24 and 10.57 person-years, respectively.
Conclusions
The air quality health risk in Jinhua City was low at most of the time from 2014 to 2021. An increase in AQHI was associated with an increased risk of YLL among population.
