ObjectiveTo investigate the role of silent information regulatory protein (SIRT6)/hypoxia-inducible factor-1α (HIF-1α) pathway in regulating the reprogramming of glucose metabolism in ulcerative colitis (UC) and the mechanism of intervention of Shaoyaotang. MethodsForty-eight c57bL/6 mice were randomly divided into a blank group, a model group, a Mesalazine group (0.42 g·kg-1), a Shaoyaotang group (31.08 g·kg-1), an inhibitor group (OSS-128167, 50 mg·kg-1), and an inhibitor + Shaoyaotang group (50 mg·kg-1 OSS-128167 + 31.08 g·kg-1 Shaoyaotang). A UC model was established by the administration of 2.5% dextran sulfate sodium (DSS) solution for mice in other groups for 7 d, except for the blank group. The mice in each group were treated with saline, Mesalazine, Shaoyaotang, inhibitor, and inhibitor + Shaoyaotang, respectively, for 7 d. The mice were necropsied 24 h after the last administration of the drug. The blood was collected from the orbital region, and colon tissue was taken. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in colon tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to detect serum interleukin (IL)-10, IL-17, and IL-6 levels. A biochemical method was used to detect glucose and lactate dehydrogenase A (LDHA) levels. Immunohistochemistry (IHC) was employed to detect IL-22 and transforming growth factor-β1 (TGF-β1) levels in colon tissue, and Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to detect relative protein and mRNA expressions of SIRT6, HIF-1α, and LDHA. ResultsCompared with those of the blank group, disease activity index (DAI) scores of mice in the model group and inhibitor group were significantly increased (P<0.01). The length of colon tissue was significantly shortened, and colon tissue was congested and eroded. The pathohistological scores were significantly increased (P<0.01). The levels of serum inflammatory factors IL-17 and IL-6 were significantly elevated, and the levels of IL-10 were significantly decreased (P<0.01). The protein expressions of IL-22 and TGF-β1 were significantly reduced in colon tissue (P<0.01). The relative protein and mRNA expressions of SIRT6 were significantly decreased (P<0.01), and the relative protein and mRNA expressions of HIF-1α and LDHA and the contents of glucose and lactate were significantly elevated (P<0.01). The level of inflammation in the colon of the mice in the inhibitor group was more severe than that in the model group (P<0.01). Compared with the model group, the Mesalazine group, the Shaoyaotang group, and the inhibitor + Shaoyaotang group showed reduced colonic injury, significant decrease in serum IL-17 and IL-6, significant increase in IL-10 (P<0.01), significant increase in the protein expressions of IL-22 and TGF-β1 in colon tissue (P<0.01), significant increase in the protein expressions of SIRT6 and the relative mRNA expressions (P<0.01), and significant reduction in the protein expressions of HIF-1α and LDHA, the relative mRNA expressions, and the contents of glucose and lactate (P<0.01). Compared with those in the Shaoyaotang group, the serum IL-17 and IL-6 were significantly increased, and IL-10 was significantly decreased in the inhibitor + Shaoyaotang group (P<0.01). The protein expressions of IL-22 and TGF-β1 in colon tissue were significantly decreased (P<0.01). The expressions of SIRT6 protein and the relative mRNA expressions were significantly decreased (P<0.01). The protein expressions of HIF-1α and LDHA, the relative mRNA expressions, and the contents of glucose and lactate were significantly elevated (P<0.01). However, the difference between the Shaoyaotang group and the Mesalazine group was not significant. ConclusionShaoyaotang can effectively treat DSS-induced mice with UC through the SIRT6/HIF-1α pathway, and its mechanism of action may be related to the regulation of the SIRT6/HIF-1α pathway and glucose metabolism reprogramming and the inhibition of glycolysis.

Objective To evaluate the protective effect of radiation protection safety education (RPSE) on patients with differentiated thyroid carcinoma (DTC) undergoing iodine-131 (131I) treatment. Methods The DTC patients who undergo 131I treatment were divided into the control group and the RPSE group using the convenience sampling method, with 142 patients in each group. Patients in the control group received routine health education, while the RPSE group received routine health education combined with RPSE. Dose equivalent rate (DER) on pillows, bed sheets, quilt covers, and household waste of patients were compared between the two groups upon discharge. Results The median (M) DERs of patients' pillows, bed sheets, quilt covers and household waste were 3.86, 3.63, 3.91 and 56.59 times higher in the control group compared with the environmental background level, respectively. The M DERs of patients' pillows, bed sheets, quilt covers were 2.23, 2.18, and 2.55 times higher in the RPSE group compared with the environmental background level, while the M DER of household waste was equivalent to the environmental background level. The DERs of patients' pillows, bed sheets, quilt covers, and household waste in the RPSE group were significantly lower than those in the control group (all P<0.001). The DERs of the above four items were lower in both male and female patients in RPSE group compared with same-gender patients in the control group (all P<0.001). The patients' DERs of the above indicators had no significant difference among different gender in both control group and RPSE group (all P>0.05), except for higher DER of household waste in female patients than that of male patients in the control group (P<0.05). There were no significant differences in the DERs of pillows, bed sheets, quilt covers, and household waste across subgroups, where patients received different treatment doses, of both the control group and the RPSE group (all P>0.05). Conclusion RPSE for DTC patients treated with 131I, reduces the DERs of pillows, bed sheets, quilt covers, and particularly household waste.

Objective :
To analyze the trends in mortality and life lost due to bladder cancer in Suzhou City, Jiangsu Province from 2003 to 2022, so as to provide the reference for prevention and treatment strategy of bladder cancer.
Methods:
The data of bladder cancer death in Suzhou City from 2003 to 2022 were collected through Suzhou Residents' Death Registration System, including age, gender, date of death and underlying cause of death. The crude mortality, standardized mortality, years of potential life lost (PYLL), standardized years of potential life lost (SPYLL), years of potential life lost rate (PYLLR), standardized years of potential life lost rate (SPYLLR) and average years of life lost (AYLL) were calculated. The average annual percent change (AAPC) was used to analyze the trends in bladder cancer death and life lost.
Results:
Totally 2 978 deaths occurred due to bladder cancer in Suzhou City from 2003 to 2022. The crude mortality was 2.22/105, which appeared a tendency towards a rise (AAPC=4.271%, P<0.05). The standardized mortality was 0.91/105, which appeared no significant changing trend (P>0.05). The standardized mortality was 1.58/105 in males and 0.37/105 in females, which appeared no significant tendency in males (P>0.05) and appeared a tendency towards a decline in females (AAPC=-2.331%, P<0.05). The age-specific crude mortality was low among people who aged under 45 years, began to rise among people aged over 45 years and peaked among people aged 60 years and older. The crude mortality of bladder cancer in males aged 60 years and older showed an increasing trend (AAPC=2.864%, P<0.05), but there was no significant tendency in females aged 60 years and older (P>0.05). The PYLL, SPYLL, PYLLR, SPYLLR and AYLL of bladder cancer were 5 020.00 person-years, 2 945.14 person-years, 0.04‰, 0.03‰ and 9.07 years per person. SPYLL, SPYLLR and AYLL showed an decreasing trend (AAPC=-2.867%, -3.321%, -3.738%, P<0.05).
Conclusions
The mortality of bladder cancer in Suzhou City appeared a tendency towards a rise from 2003 to 2022. The PYLL appeared a downward trend. Males aged 60 years and older are the key groups for the prevention and control of bladder cancer.

Randomized controlled trial (RCT) are considered the "gold standard" for evaluating the causal effects of interventions on outcome measures. However, due to high research costs and ethical constraints, conducting RCT in clinical practice, especially in the surgical field, faces numerous challenges such as difficulties in subject recruitment, implementation of blinding, and standardization of interventions. In such cases, using real-world data to perform causal inference under the framework of target trial emulation (TTE), based on the principles of RCT design, helps to identify and reduce biases arising from design flaws in traditional observational studies, such as immortal time bias, confounding, selection bias, or collider bias. This approach can produce high-quality evidence comparable to that of RCT, thereby enhancing the clinical guidance value of real-world data studies. However, TTE has limitations, such as the inability to completely eliminate confounding, high quality requirements for source data, and the current lack of reporting standards. Therefore, researchers should be fully aware of these limitations to avoid making incorrect causal inferences. This article intends to provide an overview of the TTE framework, implementation points, application scope, application cases, and advantages and disadvantages of the framework.

Objective:To evaluate the associations of sociodemographic characteristics and lifestyle factors with longevity status in older adults in China.Methods:After excluding those born after 31 st December 1938, a total of 51 870 older adults from the China Kadoorie Biobank (CKB) were included. The attained age was defined according to the survival age or age on 31 st December 2018. According to the attained age, the old persons were categorized into non-longevity (died before age 80 years) and longevity (attained age ≥80 years). The longevity group was further divided into two groups: longevity with death occurring before 2019, and longevity and survival to 2019. The information about socio-demographic characteristics and lifestyles was collected at the 2004-2008 baseline survey. Multinomial logistic regression models were used to analyze the associations between exposure factors and outcomes by taking the non-longevity group as the reference group. Results:A total of 51 870 older adults aged 65-79 years in the baseline survey were included for analysis. During a follow-up for (10.2±3.5) years, 38 841 participants were longevity, and 30 354 participants still survived at the end of 2018. Compared to men, rural populations, non-married individuals, those with an annual household income of less than 10 000 yuan, and those with education levels of primary school or below, the adjusted ORs(95% CI) for longevity and survival to 2019 in women, urban residents, married individuals, those with annual household incomes ≥20 000 yuan, and those with education levels of college or university were 1.68 (1.58-1.78), 1.69 (1.61-1.78), 1.15 (1.10-1.21), 1.44 (1.36-1.53), and 1.32 (1.19-1.48), respectively. The OR (95% CI) for longevity and survival to 2019 was 1.09 (1.08-1.10) for those with an increase of 4 MET-hour/day in total physical activity level. With those who never or almost never smoked, had no alcohol drinking every week, had normal weight (BMI: 18.5-23.9 kg/m 2), and WC <85 cm (man)/<80 cm (woman) as the reference groups, the ORs(95% CI) of longevity and survival to 2019 were 0.64 (0.60-0.69) for those smoking ≥20 cigarettes per day, 1.29 (1.14-1.46) for those with alcohol drinking every week, 1.13 (1.01-1.26) for those with pure alcohol drinking <30 g per day, 0.56 (0.52-0.61) for those being underweight, 1.27 (1.19-1.36) for those being overweight, 1.23 (1.11-1.36) for those with obesity, and 0.86 (0.79-0.93) for those with central obesity. Further stratified analysis by WC was performed. In the older adults with WC <85 cm (man)/<80 cm (woman), the ORs (95% CI) of longevity and survival was 1.80 (1.69-1.92) for those with each 5 kg/m 2 increase in BMI and 1.02 (0.96-1.08) for those with WC ≥85 cm (man)/≥80 cm (woman). There was a statistically significant difference in the association between BMI and longevity between the two WC groups (interaction test P<0.001). Conclusion:This study showed that women, the married, those with higher socioeconomic status and education level, and those with healthy lifestyles were more likely to achieve longevity.

Mirabilis jalapa L. is a plant of the family of Miraceae, native to tropical America and introduced to China during the Ming Dynasty. Its main medicinal part is the root. After sorting, it was found that the research on the medicinal properties of the Mirabilis Radixis incomplete, and the records of medicinal properties do not fully match the current application, and there is a situation of "the raw and processed for different treatments". This study further explored its medicinal properties. The Mirabilis Radix is bitter, pungent, and slight cold; belonging to the bladder, liver, and stomach meridians; it has the functions of clearing heat and dampness, detoxifying and reducing swelling, promoting blood circulation and regulating menstruation, dispelling wind and dampness, and nourishing yin. It was taken orally, with decoction, and adults should take 15-30 g, not in the form of original powder. People with spleen and stomach deficiency and cold should take it with caution, and pregnant women should not take it; for external use, an appropriate amount of fresh products should be applied and mashed. Processed Mirabilis Radix, recorded by Tujiazu medicine and Uyghur medicine, after boiling or steaming, the medicinal properties change and the nourishing effect is enhanced, but there is a lack of relevant research. Further exploration of the medicinal properties of the Mirabilis Radix can provide reference for clinical application, standard improvement, and product development.
