Objective:To clarify the changes in incidence and mortality of various cancers based on analysis on registration data of malignant tumor incidence and mortality from Dehui City and Yanji City in Jilin Province.Methods:The incidence and mortality data of malignant tumors from 2009 to 2016 in Dehui City and Yanji City in Jilin Province,were collected from the Chinese Cancer Registry Annual Report published by the National Cancer Center.The number of cases,deaths,crude incidence rate,crude mortality rate,age-standardized incidence rate(ASIR),age-standardized mortality rate(ASMR),and annual percentage change(APC)of the malignant tumors were analyzed by cancer sites and genders.Results:From 2009 to 2016,the CIR of malignant tumors in Dehui City(APC=1.2%,P=0.019)and Yanji City(APC=3.6%,P=0.058)showed an increasing trend.After standard population age adjustment,the ASIR in males in Dehui City showed a significant decline(APC=-5.7%,P=0.021),while the ASIR in females exhibited an overall downward trend,but the difference was not significant(APC=-2.2%,P=0.111).In Yanji City,the ASIR in males(APC=-1.4%,P=0.535)and females(APC=0.0%,P=0.988)showed no significant changes.The CMR of malignant tumors in Dehui City(APC=1.9%,P=0.001)and Yanji City(APC=5.9%,P=0.001)showed a continuous upward trend.After age-standardization,the ASMR in males(APC=-3.1%,P=0.100)and females(APC=-4.2%,P=0.053)in Dehui City,as well as in males(APC=-1.3%,P=0.438)in Yanji City,showed a slight downward trend.Although the ASMR in females in Yanji City showed a slight increase,the difference was not statistically significant(APC=0.5%,P=0.838).In 2016,the most common malignant tumor in terms of both incidence and mortality in Dehui City was lung cancer,with a CIR of 60.76/100 000 and a CMR of 46.96/100 000.In Yanji City,the most common malignant tumor was liver cancer,with a CIR of 49.04/100 000 and a CMR of 51.09/100 000.Conclusion:Lung cancer,liver cancer,and gastric cancer are the major malignant tumors threatening residents in Dehui City,Yanji City,and even the entire Jilin Province,and should be prioritized in cancer prevention and control efforts.Early diagnosis and treatment should be strengthened.

[Purpose]To analyze the incidence and mortality of oral and pharyngeal cancer in can-cer registration areas of Hunan Province in 2021 and the trend changes from 2012 to 2021.[Methods]Data on oral and pharyngeal cancer incidence and mortality from 2012 to 2021 were collected from 78 quality-controlled cancer registries in Hunan Province,with population data sourced from household registration statistics provided by public security authorities.Indicators such as crude incidence and mortality rates,age-standardized incidence and mortality rates by Chinese standard population(ASIRC/ASMRC),and world standard population(ASIRW,ASMRW)in 2021 were calculated.The Chinese standard population(2000 national census)and Segi's world standard population were used for standardization.Joinpoint Regression Program 4.9.0.0 software was used to fit a Log-linear regression model,and the average annual percentage change(AAPC)of ASIRC/ASMRC of oral and pharyngeal cancer from 2012 to 2021 was calculated to analyze the changing trends.[Results]In 2021,the crude incidence rate of oral and pharyngeal cancer in cancer registration areas of Hunan Province was 9.28/105(15.14/105 for males and 3.07/105 for fe-males),with an ASIRC of 6.10/105;the crude mortality rate was 3.75/105(6.19/105 for males and 1.16/105 for females),with an ASMRC of 2.16/105.Both the incidence and mortality rates in male were significantly higher than those in female.Age distribution analysis showed that the incidence rate of oral and pharyngeal cancer increased with age after 30 years old,peaking in the age group of 60～64 years old(22.29/105);the mortality rate continued to rise after 35 years old,reaching the peak in the population aged ≥85 years old(14.52/105).Trend analysis from 2012 to 2021 indicated that the crude incidence rate and ASIRC of oral and pharyngeal cancer increased from 3.50/105 and 2.63/105 in 2012 to 9.28/105 and 6.10/105 in 2021,with AAPC of 12.33％and 10.80％,re-spectively;the crude mortality rate and ASMRC also showed upward trends(AAPC of 9.87％and 7.21％,respectively);all trend changes were statistically significant(all P＜0.05).Sex stratification revealed that the AAPC of ASIRC and ASMRC of oral and pharyngeal cancer in male were higher than those in female(AAPC of ASIRC:12.65％for males vs 4.28％for females;AAPC of ASMRC:8.79％for males vs 4.13％for females).Age-specific trend analysis found that the ASIRC of oral and pharyngeal cancer in the population aged ≤ 44 years old showed an upward trend(AAPC=11.73％,P＜0.001),with the AAPC of male in this group reaching 14.57％;the AAPC of ASIRC for the age groups of 45～64 years old and ≥65 years old were 11.03％and 9.74％,respectively,and the AAPC of ASMRC for these two groups were 10.05％and 8.19％,respectively,with all trend changes being statistically significant(all P＜0.05);there was no statistically significant change in the ASMRC of the population aged ≤44 years old(AAPC=5.66％,P=0.087).[Conclusion]The incidence and mortality rates of oral and pharyngeal cancer in cancer registration areas of Hunan Province remain high and show an upward trend,with a tendency of younger onset.Males and middle-aged and elderly populations are the key focuses of prevention and control.

Objective:To compare the outcomes of simple hysterectomy(SH)and radical hysterectomy(RH)in elderly patients with cervical cancer.Methods:A retrospective cohort study was conducted, including 633 elderly patients with cervical cancer who underwent surgical treatment at Shangqiu First People's Hospital from January 2016 to December 2020.Among them, 247 patients underwent SH, and 215 patients underwent RH.Propensity score matching was applied, resulting in two groups: 125 patients in the SH group and 124 patients in the RH group.The primary outcome was the pelvic recurrence rate at 2 years of follow-up.Secondary outcomes included the incidence of urinary incontinence and urinary retention.Kaplan-Meier survival analysis was used to compare the recurrence rates between the two groups, and a Cox proportional hazards regression model was used to analyze the factors influencing recurrence rates.Results:After matching, the baseline characteristics of the two groups were similar and comparable(all P>0.05).Kaplan-Meier results showed that, although the pelvic recurrence rate in the SH group was higher than that in the RH group before matching(4.5% vs.2.3%, P<0.05), the pelvic recurrence rates were similar between the two groups after matching(3.2% vs.2.4%, P>0.05).The SH group had significantly lower postoperative complications, including urinary retention(1.6% vs.8.1%, P<0.05), compared to the RH group, while there was no significant difference in the incidence of urinary incontinence(4.0% vs.9.7%)and the risk of cervical cancer-related death(1.6% vs.0.8%)between the two groups( P>0.05).Multivariate Cox regression analysis showed that age( HR=1.254), tumor grade( HR=1.315), and FIGO stage( HR=1.203)were important factors influencing pelvic tumor recurrence during follow-up(all P<0.05). Conclusions:elderly patients with low-risk cervical cancer, the 2-year pelvic recurrence rates for SH and RH are similar.However, SH is associated with a lower risk of urinary incontinence and urinary retention.

Objective:To develop a limb function exercise program for patients on extracorporeal membrane oxygenation (ECMO) and provide theoretical guidance for clinical nursing staff.Methods:A research team was formed to systematically review domestic and international literature on functional exercise for ECMO patients, extracting relevant evidence to form the initial version of the limb function exercise program. From June to July 2023, the Delphi method was used to conduct two rounds of expert consultations with 18 experts from three provinces and municipalities directly under the central government, including Shanghai, Jiangsu, and Shanxi. Based on the experts' feedback, the program items were revised to form the final version of the exercise program.Results:In the first round, 18 experts were consulted, with a valid response rate of 94.44% (17/18); in the second round, 17 experts participated, with a 100.00% (17/17) response rate. The expert authority coefficient was 0.859 in both rounds. The coefficient of variation for each level of indicator in the second round ranged from 0 to 0.160, and Kendall's coefficient of concordance was 0.092 to 0.130 ( P<0.01). The final ECMO patient limb function exercise program consisted of four primary indicators (preparation, assessment, exercise methods, and safety monitoring), 13 secondary indicators, and 44 tertiary indicators. Conclusions:The ECMO patient limb function exercise program developed in this study is scientifically sound and reliable, offering a reference and guidance for the implementation of limb function exercises for ECMO patients.

ObjectiveTo investigate the tumor-suppressing effect of Shenqi Yiliu prescription combined with cisplatin in hepatoma H22-bearing mice based on the phosphatase and tensin homolog deleted on chromosome ten （PTEN）/phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodH22-bearing mice were prepared and randomized into model group， cisplatin group， and cisplatin combined with high-， medium-， and low-dose Shenqi Yiliu prescription groups， with 10 mice in each group. Another 10 healthy mice were randomly selected as normal group. Shenqi Yiliu prescription was given by gavage with the high， medium， low dose of 54.06， 27.03， 13.515 g·kg^-1·d^-1， respectively， and cisplatin （2.5 mg·kg^-1） was administered by intraperitoneal injection， twice a week. Normal group and model group received normal saline. After 13 days of treatment， mice were killed and the tumor inhibition rate was calculated. The pathomorphological changes of tumor were observed based on hematoxylin-eosin （HE） staining， and enzyme-linked immunosorbent assay （ELISA） and immunofluorescence method were used to detect the content of cyclin-dependent kinase inhibitor 1A （p21） and cyclin-dependent kinase inhibitor 1B （p27） in tumor tissue of mice. The levels of PTEN， PI3K and phosphorylated protein kinase B （p-Akt） in tumor tissue were measured by Western blot. ResultCompared with the model group， cisplatin alone and cisplatin in combination with the high-， medium-， and low-dose Shenqi Yiliu prescription decreased tumor mass （P<0.05）， particularly the cisplatin in combination with the high-dose Shenqi Yiliu prescription. Necrosis of the tumor tissue was observed in each group， especially the cisplatin combined with high-dose Shenqi Yiliu prescription group. As compared with the model group， cisplatin alone and cisplatin in combination with the high-， medium-， and low-dose Shenqi Yiliu prescription raised the expression of p21， p27， and PTEN （P<0.05） and lowered the expression of PI3K and p-Akt （P<0.05）， particularly the cisplatin in combination with high-dose Shenqi Yiliu prescription. ConclusionShenqi Yiliu prescription may regulate the expression of key molecules in PTEN/PI3K/Akt signaling pathway， thereby upregulating the expression of downstream proliferation inhibitors p21 and p27， further suppressing the tumor in H22-bearing mice， and enhancing the effect of chemotherapy.

Objective:To explore the significance of four-dimensional CT angiography(4D CTA) and CT perfusion (CTP) imaging in evaluating collateral circulation grades in patients with moyamoya disease and moyamoya syndrome and their relationship with cerebral hemodynamics.Methods:The clinical and imaging data of 32 patients with moyamoya disease and moyamoya syndrome in Beijing Hospital from January 2017 to January 2022 were retrospectively analyzed. All patients underwent 4D CTA-CTP imaging. Collateral circulation was scored on CTA images by using Alberta stroke program early CT score system, and on digital subtraction angiography (DSA) images by using American society of interventional and therapeutic neuroradiology/Society of interventional radiology score system, respectively. The patients were divided into Ⅰ-Ⅲ circulation compensation grades based on collateral circulation score. Regions of interest were delineated at basal ganglia on perfusion maps and the perfusion parameters were obtained including cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT), mean transit time (TTP) and delay time (DLY). The Kruskal-Wallis test was used to compare the perfusion parameters in different collateral circulation grades, and pairwise comparison was performed with Bonferroni correction. Kappa and Spearman tests were used to analyze the consistency and correlation of 4D CTA and DSA in the classification of collateral circulation.Results:4D CTA and DSA had a moderate consistency (Kappa=0.693, P<0.001) and a strong correlation ( r=0.805, P<0.001) in evaluating collateral grades. There were statistically significant differences in CBF, MTT and TTP among collateral compensation grade Ⅰ, grade Ⅱ and grade Ⅲ ( H values were 7.91, 11.69, 8.93; P values were 0.019, 0.003 and 0.012, respectively). Further pairwise comparison showed that the CBF of collateral compensation grade Ⅰ was lower than that of grade Ⅲ ( P=0.015), MTT of grade Ⅱ was higher than that of grade Ⅲ ( P=0.005), and TTP of grade Ⅰ was higher than that of grade Ⅲ ( P=0.015). There was no statistical significance of other indicators in pairwise comparison. There were no significant differences in CBV and DLY among collateral compensation grade Ⅰ, grade Ⅱ and grade Ⅲ ( P>0.05). Conclusions:4D CTA-CTP is equivalent to DSA in evaluating collateral circulation in patients with moyamoya disease and moyamoya syndrome. It can also evaluate the cerebral hemodynamics comprehensively, which has high clinical significance for disease monitoring.

Objective:To study the effects of Zuogui Pills on the expressions of miR-133b-3p and RhoA in osteoclasts of postmenopausal osteoporosis rats; To discuss its potential mechanism.Methods:SD female rats were randomly divided into normal group, model group, sham-operation group, and Zuogui Pills group using a random number table method, with 6 rats in each group. The model group and Zuogui Pills group were treated with oophorectomy to construct a rat model of osteoporosis. Zuogui Pills group was orally administered with Zuogui Pills decoction at a concentration of 10 g/kg for 12 consecutive weeks. Colorimetric method was used to measure the serum calcium and phosphorus levels of rats, and ELISA method was used to detect ALP levels. Bone density meter was used to measure the bone density of the femurs of rats in each group. The osteoclast of each group were cultured, and the expressions of RANKL and RUNX2 protein were detected by Western blot. MiRNA sequencing and differential expression analysis were performed on bone tissues of rats. Osteoclasts were treated with miR-133b-3p mimic and its negative control. The cell proliferation activity of osteoclasts was detected by cell counting kit-8 (CCK-8). The osteoclast differentiation activity was detected by the tartrate-resistant acid phosphatase staining. The dual-luciferase reporter assay was used to detect the relationship between miR-133b-3p and RhoA. The "rescue" experiment of miR-133b-3p mimic and RhoA co-expression were used to study the molecular regulatory mechanism of Zuogui Pills on osteoclast activity.Results:Compared with the model group, the bone mineral density of Zuogui Pills group significantly increased ( P<0.05, P<0.01), the levels of calcium and phosphorus in serum increased, the level of alkaline phosphatase ALP decreased ( P<0.05), the expression of RANKL protein decreased, and the expression of RUNX2 protein increased. Sequencing results showed that rno-miR-133b-3p was down-regulated in osteoclasts of postmenopausa osteoporosis rats treated with Zuogui Pills with the maximum difference ( P<0.01). Q-PCR results showed that the expression of miR-133b-3p in osteoclasts of Zuogui Pills group was significantly lower than that of the model group. The upregulation of miR-133b-3p could significantly promote the cell proliferation and differentiation of osteoclasts. RhoA overexpression could reverse the excessive proliferation and differentiation of osteoclasts caused by miR-133b-3p overexpression. Conclusions:RhoA is the target gene regulated by miR-133b-3p. Zuogui Pills can inhibit the activity of osteoclasts by regulating miR-133b-3p/RhoA axis, relieving the symptoms of osteoporosis.

Abstract Benzo [a] pyrene ( B [a] P ) is a well-recognized environmental pollutant. Exposure to B[a]P elicits many adverse biological effects, including tumorigenesis, immunosuppression, teratogenicity, and hormonal effects. In addition to B [a] P exposure-induced genetic damages, a growing number of studies demonstrate that epigenetic changes play an important role in chemically induced carcinogenesis. In order to provide better understanding of epigenetic changes of B [a] P and their potential association with genotoxic endpoints, this review summarizes the advances in the applications of functional genomics in the research of B [a] P toxicity, including functional genomics techniques, regulation of human genome expression, DNA sequence variability, model organisms research, and bioinformatics studies, so as to provide insights into the management of B [a] P exposure-induced health injuries and use of genomics techniques to unravel the mechanisms underlying the toxicity of other environmental pollutants.
