Background Previous studies found that high temperature and heatwave increase the risk of traffic injuries. The complex road conditions in Yunnan Province result in frequent traffic accidents. However, there is limited evidence on the correlation between heatwave and traffic injuries in Yunnan Province. Objective To assess the association between heatwave events and traffic injuries, to estimate its disease burden, and to identify relevant sensitive groups. Methods We collected data on traffic injury cases and concurrent meteorological information from four surveillance sites in Yunnan Province, China: Dali, Lufeng, Zhaoyang, and Qilin from May to September each year from 2015 to 2023. Traffic injury cases refer to patients who visited the outpatient or emergency departments of local surveillance hospitals for the first time due to traffic injuries. Meteorological data were derived from the fifth generation atmosphericreanalysis dataset of the global climate provided by the European Centre for Medium-Range Weather Forecasts. A time-stratified case-crossover design combined with distributed lag non-linear model was used to analyze the association between short-term exposure to heatwave and traffic injuries. We also conducted subgroup analyses by sex, age, occupation, injury cause, activity at the time of injury occurrence, and severity of injury. Results A total of 34764 traffic injury surveillance cases were included in the analysis. The risk of traffic injuries occurred during heatwave was 1.13 times (95%CI: 1.07, 1.20) greater than those occurred during non-heatwave, and 2.64% (95%CI: 1.49%, 3.73%) of traffic injuries were attributed to heatwave exposure throughout the study period. The results of stratified analysis showed greater impacts of heatwave on the risk of traffic injuries in female [odds ratio (OR)=1.17, attributable fraction (AF)=3.23%], people aged 15-64 years (OR=1.13, AF=2.68%), farmers/workers (OR=1.22, AF=4.07%), people with non-motor vehicle traffic injuries (OR=1.17, AF=3.24%), people who were driving or riding when injuries occurred (OR=1.12, AF=2.43%), and people with minor injuries (OR=1.18, AF=3.49%) ( P<0.05). Longer duration [excess risk (ER)=0.99%] and greater intensity (ER=4.12%) of heatwave had greater impacts on the risk of traffic injuries (P<0.05). Conclusion Heatwave events are associated with an increased risk of traffic injuries. Female, people aged 15-64, farmers/workers, people with non-motor vehicle traffic injuries, those injured while driving/riding a vehicle, and people with minor injuries are particularly vulnerable. The findings suggest that targeted mitigation and adaptation measures should be taken to address the risk of traffic injuries associated with extreme climate events.

ObjectiveTo investigate the triglyceride-glucose (TyG) index and the level of serum homocysteine (Hcy) in association with the incidence of stroke in type 2 diabetes mellitus (T2DM) patients. MethodsBased on the chronic disease risk factor surveillance cohort in Pudong New Area, Shanghai, excluding those with stroke in baseline survey, T2DM patients who joined the cohort from January 2016 to October 2020 were selected as the research subjects. During the follow-up period, a total of 318 new-onset ischemic stroke patients were selected as the case group, and a total of 318 individuals matched by gender without stroke were selected as the control group. The Cox proportional hazards regression model was used to adjust for confounding factors and explore the serum TyG index and the Hcy biochemical indicator in association with the risk of stroke. ResultsThe Cox proportional hazards regression results showed that after adjusting for confounding factors, the risk of stroke in T2DM patients with 10 μmol·L⁻¹-¹ and Hcy>15 μmol·L⁻¹ was 1.532 times (95%CI: 1.017‒2.309 times, P=0.041) and 1.738 times (95%CI: 1.119‒2.699 times, P=0.014) higher respectively, compared to T2DM patients with Hcy≤10 μmol·L⁻¹. T2DM patients with TyG>9.074 had 1.396 times higher risk of stroke (95%CI: 1.091‒1.787, P=0.008) compared to those with TyG≤9.074. The study found that urea and α1-antitrypsin (α1-AT) were independent risk factors for the incidence of stroke in T2DM patients. For every unit increase in urea andα1-AT, the risk of stroke in T2DM patients increased by 233.6% (HR=3.336, 95%CI: 1.588‒7.009, P=0.001) and 11.3% (HR=1.113, 95%CI: 1.028‒1.205, P=0.008), respectively. Cumulative risk curves showed that Hcy>10 μmol·L⁻¹ and TyG>9.074 accelerated the time to stroke occurrence in T2DM patients. ConclusionElevated levels of Hcy>10 μmol·L⁻¹ and a higher TyG index are risk factors for stroke in T2DM patients. Effective interventions for Hcy and TyG should be conducted for diabetic patients to reduce the incidence of stroke.

The paper summarizes Professor YANG Jun's experience in treatment of refractory facial paralysis with the refined mode of acupuncture and moxibustion, so as to provide new ideas and methods for the disease treated with acupuncture and moxibustion. Professor YANG Jun puts forward the refined mode of diagnosis and treatment of acupuncture and moxibustion for refractory facial paralysis. On the basis of syndrome/pattern differentiation of TCM, combined with meridian theory and modern anatomy, the symptom differentiation and meridian differentiation are performed accurately. By selecting local acupoints (e.g. Touwei [ST8], Sibai [ST2], Cuanzhu [BL2] and Yangbai [GB14]), distal acupoints (e.g. Zusanli [ST36], Hegu [LI4] and Jinsuo [GV8]), specific acupoints (e.g.Qianzheng [EX-HN16] and Touqiaoyin [GB11]) and the acupoints for regulating the mind (e.g. Dazhui [GV14] and Shuigou [GV26]), the prescription is composed. The different needling techniques are delivered at the acupoints (e.g. point-to-point needling with long needle, stuck needling by lifting and dragging, and balance needling on the healthy side). Besides, the facial rehabilitation is considered as the adjuvant treatment. This mode of treatment obtains the precise diagnosis and treatment to achieve the utmost therapeutic effects.

ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease（COPD） patients， and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease（COPD） patients. MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management， and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat， mobile phone short message service（SMS）and telephone. Finally， a total of2 589 subjects were included in the analysis， including 1 300 in the intervention group and 1 289 in the control group. General demographic data， past medical history and family history of COPD， COPD related knowledge and practice survey， COPD related symptom assessment， acute onset， health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack， health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect. ResultsIn terms of acute attacks， after intervention， the incidence of acute attacks in the intervention group was lower than that before intervention（χ²=52.901， P<0.001）， and the incidence of acute attacks in the groups with different intervention methods was lower than that before intervention （P<0.001）. WeChat had the best effect， decreasing the incidence by 14.4%， followed by mobile phone SMS SMS decreasing by 12.3%. In terms of utilization of health services， the outpatient rate due to acute attack was lower in the intervention group after intervention than that before intervention （χ²=7.129， P=0.008）， and the outpatient rate due to acute attack was lower in the subjects who received the forecast service through mobile phone SMS than that before intervention （χ²=4.675， P<0.001）. In terms of medical expenses， there was no significant difference between control group and intervention group with different intervention methods before intervention （P>0.05）. After intervention， the difference between the control group and the intervention group with different intervention methods was statistically significant （H=11.864， P<0.05）. The results of multiple comparisons showed that compared with the control group， the average annual medical expenses of patients receiving mobile phone SMS and telephone forecasting services after intervention were lower than those of the control group， and the difference was statistically significant （P<0.05）. ConclusionMeteorological risk forecasting service can reduce the acute onset of COPD， reduce the rate of consultation and medical expenses due to acute onset， and provide scientific basis for the basic COPD health management model.

Objective To understand the proficiency level and sources of Traditional Chinese Medicine(TCM)health education among hemodialysis patients,in order to provide the basis for promoting the application of TCM nursing in hemodialysis patients.Methods Utilizing a convenience sampling approach,we conducted a survey from April to May 2023 involving hemodialysis patients from 7 tertiary TCM hospitals across Beijing,Hebei Province,Sichuan Province,and other regions.Custom-made questionnaires were utilized,gathering general information,respons-es conceming the level of mastery on TCM health education,and their primary sources of such knowledge.Results A total of 413 questionnaires were disseminated,and 392 proved valid,yielding a valid response rate of 94.92％.The score of patient's knowledge on TCM health education averaged(8.25±3.73),and an average score rate of 48.53％was obtained.In the patients undergoing hemodialysis,a relatively larger number of people possess knowl-edge of TCM health knowledge about relieving symptoms(50.8％～55.9％)and traditional Chinese daily life routines(56.4％～90.1％).However,fewer people are aware of how to use the five-tone therapy method for emotional inter-vention(40.8％)and principle of taking restorative Traditional Chinese Medicine(24.5％～36.7％),the dietary prin-ciples of"nurturing yang in spring and summer,and nurturing yin in autumn and winter"(14.3％),and theories of TCM kidney functions(9.9％).Approximately 23.0％of the patients sourced their TCM health education knowledge from new media platforms.Compared with new media method alone,patients who utilized only traditional education-al platforms(P=0.020),and those who combined both new media and traditional methods(P=0.018)demonstrated higher proficiency in TCM health education.Conclusion Hemodialysis caregivers are urged to develop a TCM health education framework that emphasizes emotional well-being and traditional wellness concepts,thereby fostering patient-centric TCM health ideologies.Hemodialysis education personnel are encouraged to leverage new media whilst ensuring education quality and effective outcomes.

Objective:To investigate the influencing factors of breakthrough cancer pain (BTcP) in patients with advanced pancreatic cancer.Methods:According to the inclusion and exclusion criteria, patients with advanced pancreatic cancer who were diagnosed and followed up by outpatient service in the 909th Hospital of the Joint Logistic Support Force from January 2019 to December 2020 were prospectively selected as the study subjects. According to whether breakthrough cancer pain occurred, all patients were divided into observation group (breakthrough cancer pain) and control group (no breakthrough cancer pain). The relevant clinical data of the included patients including age, gender, presence or absence of vomit, constipation, sleep disruption, frequency of basic pain every week, with or without regular medication, heavy physical labor, with or without vascular invasion, bone metastasis, abdominal metastasis and lung metastasis, as well as whether surgery, radiotherapy or chemotherapy were collected and the data of evaluation indicators during follow-up were recorded. Digital pain score (NRS) and visual analog score (VAS) were used as pain evaluation score. Univariate and logistic regression were used to analyze the related influencing factors of breakthrough cancer pain. Receiver operating characteristic curve (ROC) was drawn, and area under curve (AUC), sensitivity and specificity were calculated to analyze the predictive value for breakthrough cancer pain.Results:A total of 173 patients were included in the study, with 49 cases in the observation group and 124 cases in the control group. Univariate analysis showed that aged ≥50 years old, constipation, sleep disruption, frequency of basic pain ≥3 times, irregular medication, heavy physical labor, bone metastasis, lung metastasis, radiochemotherapy, high NRS score and high VAS score were the influencing factors for breakthrough cancer pain (all P value <0.05). Multivariate analysis showed that irregular medication ( OR=1.879, 95% CI 2.473-4.757, P=0.002), basal pain ≥3 times ( OR=2.067, 95% CI 1.364-6.825, P=0.004), bone metastasis ( OR=2.756, 95% CI 1.153-5.846, P<0.001), NRS score ( OR=3.787, 95% CI 2.647-5.958, P<0.001), VAS score ( OR=2.684, 95% CI 1.545-7.878, P<0.001), were the risk factors for breakthrough cancer pain. The AUC of NRS score for predicting the occurrence of breakthrough cancer pain was 0.665 (95% CI0.573-0.757, P=0.001), and the cut-off value was 2.5 score with a sensitivity of 61.2% and a specificity of 77.1%. The AUC for predicting breakthrough cancer pain by VAS score was 0.608 (95% CI0.515-0.701, P=0.028), and the cut-off value was 2.5 score with a sensitivity of 67.9% and a specificity of 63.7%. The AUC of NRS+ VAS score for predicting breakthrough cancer pain was 0.692 (95% CI0.604-0.780), and the cut-off value was 4.5 score with a sensitivity of 81.6% and a specificity of 79.8%. Conclusions:Patients with advanced pancreatic cancer have a high incidence of breakthrough cancer pain, which was related to a variety of factors. NRS combined with VAS score can effectively predict the occurrence of breakthrough cancer pain.

Conclusions:All patients have a certain degree of relief after DBS without obvious adverse reactions.DBS is an effective treatment for pediatric dystonia.

[Abstract] Objective: To investigate the effect of metformin on the senescence-associated secretory phenotype (SASP) of doxorubicin-induced gastric cancer BGC823 cells. Methods: Human gastric cancer BGC823 cells were cultured in vitro and treated with doxorubicin at gradient concentrations (50, 100, 150 and 200 nmol/L). Cell senescence was detected by SA-β-gal staining, and SASP factor expression was detected by ELISA. The effects of metformin on cell senescence and SASP factor secretion induced by doxorubicin (100 nmol/L) were observed by adding gradient concentrations of metformin (0, 5, 10 and 20 mmol/L). Results: With the increase of doxorubicin concentration and treatment time, the senescence rate of gastric cancer BGC823 cells increased first and then decreased. At 96 h after 100 nmol/L doxorubicin treatment, the peak aging rate reached 68.7%, accompanied with significantly increased expressions of SASP factors IL-1a, IL-6, IL-8 and CXCL1. The proportion of senescent cells was (55.2±1.9)%, (48.7±2.2)% and (40.8±2.3)% respectively under the effects of 5, 10 and 20 mmol/L metformin, which was significantly lower than that in the non-metformin treatment group (P< 0.01). At the same time, with the increase of metformin concentration, the production of SASP factors IL-1α, IL-6, IL-8 and CXCL1 showed a gradient decline. Compared with the non-metformin treatment group, IL-6 and IL-8 decreased significantly under the effect of metformin above 10 mmol/L (P<0.05 or P<0.01), while IL-1α and CXCL1 decreased significantly under the effect of 20 mmol/L metformin (all P<0.05). Conclusion: Metformin can inhibit the senescence and SASP production of gastric cancer cells induced by doxorubicin.
