Objective To observe the intervention effect of acupuncture at"Zusanli"(ST36)or"Neiguan"(PC6)on the ulcerative colitis(UC)model mice.And to analyze the similarities and differences of gene transcription expression between the diseased colon and the non-diseased heart after acupuncture intervention by using transcriptomics,to explore whether there are efficacy differences between the two acupoints.Methods The UC mouse model was established by inducing dextran sulfate sodium salt(DSS).After successful modeling,the mice were randomly divided into model group,Zusanli group,and Neiguan group,with 9 mice in each group.Zusanli group and Neiguan group intervened with acupuncture at"Zusanli"and"Neiguan",respectively,30 min each time,once a day,for 5 consecutive days.The control and model groups were only bound without acupuncture.Observe the general situation of mice in each group,calculate the disease activity index(DAI),observe the morphological changes of colon tissue by HE staining.Use transcriptome sequencing technology to sequence and biologically analyze the colon tissue of mice in each group,and compare and study whether the two acupoints have differences in acupoint efficacy from the perspective of diseased tissue.At the same time,take the heart tissues of each group for comparative analysis,and discuss whether the effects of the two acupoints are different from the perspective of non-diseased tissue.Results Compared with control group,the DAI score of the model group increased significantly(P<0.001),and HE staining results showed significant pathological damage;after acupuncture at Zusanli or Neiguan,the DAI scores of UC mice were reduced considerably(P<0.05),and the pathological damage was significantly improved.The results of transcriptome sequencing and bioinformatics analysis showed that the effects of acupuncture at Zusanli or Neiguan on the colon of diseased tissue involved multiple genes,and 825 differential genes with similar changes(co-DEGs)were mainly enriched in white blood cells and chemokine pathways;there were 168 differentially expressed genes(ST36 only-DEGs)affected only by Zusanli,which were enriched to gastric acid secretion and other pathways;there were 325 differentially expressed genes(PC6 only-DEGs)only affected by Neiguan,which were enriched in cytokine-cytokine receptor interaction and other pathways.There were 95 co-DEGs in the heart of non-diseased tissue,which were mainly enriched in positive regulation of defense response and response to interleukin-1;there were 28 ST36 only-DEGs;there were114 PC6 only-DEGs,which were enriched in cardiovascular diseases and other pathways.Conclusion Acupuncture of"Zusanli"and"Neiguan"could improve UC mice's symptoms and pathological colon changes.However,through transcriptomic analysis,it was found that the two acupoints had differences in gene transcription effects on the colon of diseased tissue and the heart of non-diseased tissue,suggesting that acupoints with different distribution positions had some similarities in macro efficacy.Still,there were some differences at a micro level.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

Objective:To evaluate the relationship between gluten-free diet and rheumatoid arthritis (RA).Methods:Data were obtained from large-scale genome-wide association studies (GWAS), and genetic loci that are independent of gluten-free diet and RA of people of Europe2 were selected as instrumental variables. The gluten-free diet GWAS data included 64 949 individuals and 9 851 867 controls. Data were obtained from GWAS of 58 284 RA patients and 13 108 512 controls. The inverse variance weighted (IVW), MR Egger, weighted median method and weighted model were used to conduct two sample Mendelian randomization (MR) analysis. Cochran Q test and mendelian randomness pleiotropy residual sum and outlier (MR-PRESSO) were used to assess SNP heterogeneity. Applying the MR Egger intercept to test the level pleiotropy of SNP. The sensitivity analysis of the "leave one method" that evaluates whether MR studies were influenced by a single SNP. Results:After matching GFD and RA data, three SNPs were included as instrumental variables in the study. IVW showed that GFD could significantly reduce the risk of RA ( β=-60.83, s x=3.82, P<0.001). The weighted median method and weighted pattern also showed that the gluten free diet could reduce the risk of RA ( β=-57.97, s x=4.41, P<0.001; β=-55.81, s x=5.10, P=0.008). Sensitivity analysis of the correlation between GFD and RA showed that there might be heterogeneity between SNPs (Cochran Q test, Q=12.80, P=0.002). The MR-PRESSO results showed that no abnormal SNP was detected ( P=0.174). The forest map showed that SNPs was closely related to GFD and RA stability. The method comparison chart showed that the results of multiple testing methods were basically consistent. The funnel plot showed that SNPs were basically symmetrical, indicating that there was no pleiotropy in MR analysis. The MR Egger intercept test showed no horizontal pleiotropy in MR analysis (intercept value was-0.24, P=0.174). The sensitivity analysis of the "leave one method" is suggested that no single SNP had a significant impact on the overall results. Conclusion:Gluten free diet is related to the risk reduction of RA.

Objective:To design and evaluate the application value of intracavitary-interstitial brachytherapy (IC-ISBT) applicator template for locally advanced cervical cancer.Methods:MRI data of 100 patients with ⅡB-ⅣA stage cervical cancer (International Federation of Gynecology and Obstetrics 2018 staging system) before and after external beam radiation therapy (EBRT) admitted to Sun Yat-sen University Cancer Center from March 2019 to September 2020 were collected. The range of primary cervical lesions was retrospectively analyzed and compared. Based on the residual mass of patients, the corresponding high-risk clinical target volume (HR-CTV) was delineated, and the IC-ISBT applicator template was designed and initially applied to cervical cancer patients. Dosimetry analysis and efficacy evaluation were compared between the applicator template-guided ( n=37) and free-hand implantation groups ( n=63). Chi-square test or Fisher exact test was performed for categorical variables, and t-test or U-test for continuous variables. Results:The median distance between the residual tumor margin (clockwise 3, 6, 9, 12 o'clock) and the center of 100 patients with ⅡB-ⅣA stage cervical cancer after EBRT was 16.5, 14.0, 17.0 and 13.0 mm, respectively. The corresponding HR-CTV was superimposed to reconstruct the three-dimensional diagram, and the cylindrical IC-ISBT applicator template with mushroom-like head was designed and manufactured: the longest and shortest diameter of the head was 35 and 20 mm, respectively; the central channel was adapted to the uterine tube, the C1-C12 channels was arranged in inner circle, and the peripheral B1-B5 and A1-A4 pin channels were expanded bilaterally. In terms of dose coverage, there was no significant difference between the HR-CTV D 90% [(635.12±22.65) vs. (635.80±25.84) cGy], bladder D 2 cm3 [(473.79±44.78) vs. (463.55±66.43) cGy)], rectum D 2 cm3 [(396.99±73.54) vs. (408.00±73.94) cGy] and sigmoid colon D 2 cm3 [(293.07±152.72) vs. (311.31±135.77) cGy] between the template-guided and free-hand implantation groups (all P>0.05), but the HR-CTV D 98% was significantly higher [(544.78±32.07) vs. (536.78±32.04) cGy, P=0.007] and the rectum D 1 cm3 and D 0.1 cm3 were significantly lower [(438.62±69.65) vs. (453.97±67.89) cGy, P=0.016; (519.46±70.67) vs. (543.82±81.24) cGy, P=0.001] in the template-guided implantation group. In addition, there was no significant difference in the complete response rate between two groups (86% vs. 83%, P>0.05). Conclusions:This IC-ISBT applicator template is reasonably designed, and the therapeutic efficacy of the template-guided implantation is equivalent to that of free-hand implantation. The dose coverage of the target area meets the clinical demand with a better protection of the organs at risk. The applicator template has the potential to be widely used as a conventional template in clinical practice as the applicator-guided implantation is convenient to operate and repeat.

Objective:To summarize evidence for physical activity management in cancer patients based on the Joanna Briggs Institute (JBI) approach for evidence synthesis in health care, providing a scientific basis for the clinical standardization of physical activity management in cancer patients.Methods:Literature was searched according to the "6S" pyramid model of evidence, using BMJ Best Practice, UpToDate, JBI Evidence-Based Practice Database, Cochrane Library, global guideline websites, professional cancer association websites, and relevant Chinese and English databases for all evidence regarding physical activity in cancer patients. The search covered the period from February 13, 2018, to February 13, 2023. Guided by the JBI approach for evidence synthesis, two researchers independently evaluated the quality of the literature and extracted relevant evidence in accordance with clinical scenarios.Results:Thirty articles were included, comprising two guidelines, three expert consensuses, one evidence summary, 21 systematic reviews, and three randomized controlled trials. A total of 29 best evidence points were summarized in six aspects: benefits of physical activity, physically active people, pre-activity assessment, implementation of physical activity programs, safety monitoring of physical activity, and ongoing support strategies.Conclusions:This study supplements and updates 15 pieces of evidence based on existing evidence, ultimately forming a best evidence summary for the management of physical activity in cancer patients, providing evidence-based support for clinical management. Most evidence comes from international studies. It is recommended that Chinese researchers consider the activity ability and willingness of cancer patients when applying these findings in future research, and consider the specific clinical context, or conduct foundational research to further validate the evidence, to comprehensively improve the quality of life of cancer patients.

Objective To explore the clinical diagnostic and prognostic value of serum levels of Syndecan-1 and pentraxin 3(PTX-3)in patients with multiple organ dysfunction syndrome(MODS)complicated by multiple injuries.Methods A sum of 140 patients with multiple injuries admitted to Tangshan Central Hospital from January 2022 to June 2023 were collected prospectively as the research subjects,and they were divided into MODS group(n=49)and non MODS group(n=91)based on the presence or absence of concurrent MODS.According to the survival status of the patients within 28 days of admission,the MODS group was grouped into a survival group(n=21)and a death group(n=28).Enzyme linked immunosorbent assay(ELISA)was applied to measure the expression levels of Syndecan-1 and PTX-3 in serum,and the diagnostic value of serum Syndecan-1 and PTX-3 in MODS and their predictive efficacy in predicting the prognosis of patients with multiple injuries combined with MODS were analyzed using the receiver operating characteristic(ROC)curve analysis.Results The ISS score,acuse physiology and chronic health evaluation(APACHE)Ⅱ score,and serum Syndecan-1 and PTX-3 expression levels in the MODS group(24.41±5.22 scores,22.02±4.41 scores,77.76±8.25 ng/ml,34.87±4.53 pg/ml)were higher than those patients with no MODS group(18.62±4.06 scores,16.69±3.54 scores,63.98±7.52 ng/ml,25.43±3.97 pg/ml),and the differences were statistically significant(t=7.265,7.783,9.994,12.766,all P＜0.05).The AUCs of serum Syndecan-1 and PTX-3 for predicting the prognosis of patients with multiple injuries and MODS alone were 0.845 and 0.792,respectively,while the AUC of combined diagnosis of the two was 0.941,and the diagnostic value of the combination of the two for multiple injuries with MODS was superior to that of Syndecan-1 and PTX-3 separately(Z=4.029,2.681,P=0.001,0.007),while the sensitivity of the combined diagnosis of the two was significantly higher than that of conventional inflammatory indicators IL-6 and PCT diagnosis.The expression levels of Syndecan-1(85.17±9.03 ng/ml)and PTX-3(40.20±5.21 pg/ml)in the serum of patients in the death group were higher than those in the survival group(67.90±7.22 ng/ml,27.77±3.64 pg/ml),and the differences were statistically significant(t=7.201,9.345,all P＜0.05).The AUCs predicted by serum Syndecan-1 and PTX-3 alone were 0.845 and 0.792,respectively,while the AUC predicted by the combination of the two was 0.932.The combined prediction of multiple injuries with MODS was superior to Syndecan-1 and PTX-3 separately(Z=1.982,2.311,P=0.047,0.020),and it has certain predictive value for the prognosis of patients with multiple injuries combined with MODS.Conclusion The expression levels of Syndecan-1 and PTX-3 in serum are related to the occurrence of multiple injuries with MODS.The combined detection of the two has high diagnostic and prognostic value for multiple injuries with MODS.

Objective To observe the ultrasonic manifestations and possible etiology of fetal tricuspid regurgitation(TR).Methods Totally 717 fetuses diagnosed with TR by prenatal ultrasound were retrospectively enrolled,and the prenatal ultrasonic findings were observed.Based on postpartum follow-up data,the fetuses were divided into physiological TR group(n=468)and pathological TR group(n=249),and those in the latter were further divided into right heart preload increase subgroup(n=76),right heart afterload increase subgroup(n=127)and tricuspid valve structure abnormality subgroup(n=46)according to the possible etiology,and the ultrasonic manifestations were comparatively analyzed.Results In physiological TR group,mild and moderate TR was found in 441(441/468,94.23％)and 27 fetuses(27/468,5.77％),respectively,while no severe TR was noticed.In pathological TR group,significant difference of TR degrees was found among 3 subgroups(x2=37.244,P＜0.001).Mild TR was more common in right heart preload increase subgroup,while moderate and severe TR were more common in the other 2 subgroups.In right heart preload increase subgroup,fetuses with persistent left superior vena cava were more likely to develop mild TR,while those with intact interventricular septum and pulmonary artery occlusion were more likely to develop severe TR in right heart afterload increase subgroup(both P＜0.05).No significant difference of TR degree was found among fetuses with different possible etiology in right heart preload increase subgroup nor right heart afterload increase subgroup(both P＞0.05).In tricuspid valve structure abnormality subgroup,significant differences of TR degrees were found among fetuses with different possible etiologies(P＜0.05),and fetuses with underdeveloped tricuspid valve were more prone to severe reflux(P＜0.05).There were significant differences of reflux velocity of moderate and severe TR among 3 subgroups(F=6.945,P=0.002).Conclusion Fetal TR was mostly physiological.The possible etiologies of pathological TR were variable,including pulmonary valve stenosis,persistent left superior vena cava and tricuspid valve hypoplasia,with different prenatal ultrasonic manifestations.

Objectives: . We aimed to develop a new calculation model for calcium requirements in dialysis patients following parathyroidectomy. Methods: . A total of 98 patients with secondary hyperparathyroidism receiving parathyroidectomy from January 2014 to January 2022 were enrolled in this study. Among these patients, 78 were randomly selected for construction of the calcium requirement calculation model, and the remaining 20 patients were selected for model validation. The calcium requirement model estimated the total calcium supplementation for 1 week after surgery using variables with significant relationships in the derivation group by stepwise multiple linear regression analysis. Bias, precision, and accuracy were measured in the validation group to determine the performance of the model. Results: . The model was as follows: calcium requirement for 1 week after surgery=33.798–8.929×immediate postoperative calcium+0.190×C-reactive protein–0.125×age+0.002×preoperative intact parathyroid hormone+0.003×preoperative alkaline phosphatase (R2=0.8). The model was successfully validated. Conclusion . We generated a novel model to guide calcium supplementation. This model can assist in stabilizing the serum calcium levels of patients during the early postoperative period. Furthermore, it contributes to the individualized and precise treatment of hypocalcemia in patients following parathyroidectomy.
