BACKGROUND: Premature menopause, defined as natural menopause before age 40, is associated with diminished ovarian reserve. Despite growing concerns regarding environmental pollutants, no large-scale population-based studies have systematically examined the association between urinary polycyclic aromatic hydrocarbon metabolites (UPAHMs) and premature menopause. METHODS: This cross-sectional study analyzed 2001-2020 NHANES data, including urinary levels of six PAH metabolites: 1-naphthol (1-NAP), 2-naphthol (2-NAP), 3-fluorene (3-FLU), 2-fluorene (2-FLU), 1-phenanthrene (1-PHE), and 1-pyrene (1-PYR). Premature menopause was self-reported as natural menopause occurring before age 40. Multivariable logistic regression assessed UPAHMs' association with premature menopause, with restricted cubic splines (RCS) evaluating nonlinear trends. Subgroup analyses examined demographic interactions. RESULTS: Among 2,565 participants, 662 reported premature menopause. Multivariable logistic regression showed significant associations between elevated urinary levels of 1-NAP (OR: 1.01, 95% CI: 1.00-1.02, P = 0.02), 2-NAP (OR: 1.01, 95% CI: 1.00-1.02, P = 0.02), and 3-FLU (OR: 1.03, 95% CI: 1.01-1.05, P = 0.01) and increased risk of premature menopause. RCS analysis revealed significant nonlinear relationships for 2-NAP, 3-FLU, 2-FLU, 1-PHE, and 1-PYR with premature menopause risk. White participants showed greater susceptibility to UPAHMs. CONCLUSION Elevated UPAHMs, particularly 1-NAP, 2-NAP, and 3-FLU, were linked to higher premature menopause risk, with nonlinear trends observed. White individuals demonstrated greater vulnerability, emphasizing the need for targeted interventions to reduce PAH exposure.

Background Injury poses a serious threat to human health. As global warming continues to intensify, there is an urgent need to explore the impact of temperature changes on injury deaths. However limited research has focused on this issue. Objective To investigate the relationship between daily mean temperature change (Tm) and injury death, as well as to estimate the associated future death burden in Hunan Province. Methods We employed an individual-level, time-stratified case-crossing design to establish a conditional logistic regression model to analyze the exposure-response relationship between daily mean temperature change and injury death in Hunan Province from 2013 to 2018. Consequently, we conducted subgroup analysis of gender, age group, and injury type. Finally, we estimated the excess burden of injury death attributable to temperature changes under a sustainable development path [low emission scenario (SSP1-2.6)], regional competition path [high emission scenario (SSP3-7.0)], or fossil fuel development path [very high emission scenario (SSP5-8.5)]. Results The study collected 155577 injury deaths in Hunan Province. The results indicated that for each 1 ℃ increment in daily mean temperature, the cumulative excess risk (CER) of injury mortality among Hunan residents increased by 0.71% (95%CI: 0.53%, 0.90%). Notably, the CER for intentional injuries (1.06%, 95%CI: 0.51%, 1.61%) was higher than that for unintentional injuries (0.66%, 95%CI: 0.46%, 0.87%). Warmer temperatures were positively associated with CER of mortality due to drowning, falls, transport injuries, assaults, and suicides, while they were negatively associated with mortality due to poisoning. Compared with 2010–2019, for 2090–2099, the excess mortality rate (EMR) due to ambient temperature increase in Hunan Province under the SSP5-8.5 scenario (14.62/100000, 95%CI: 10.81/100000, 18.40/100000) would be higher than that of the SSP3-7.0 scenario (10.28/100000, 95%CI: 7.58/100000, 12.97/100000) and the SSP1-2.6 scenario (3.35/100000, 95%CI: 2.46/100000, 4.23/100000); the EMR would be around 2.5 times among men (20.64/100000, 95%CI: 14.44/100000, 26.8/100000) than that among women (8.33/100000, 95%CI: 3.98/100000, 12.6/100000). Among unintentional injuries, the leading contributors to EMR would be drowning (4.46/100000), falls (3.96/100000), and transport injuries (2.96/100000). And among intentional injuries, the EMR for suicide (2.08/100000) would be higher than that for assault (0.47/100000). Conclusion Climate warming will increase the total burden of injury-related deaths among residents in Hunan Province, especially in the absence of effective mitigation strategies and measures. It is necessary to strengthen the prevention and control of severe injuries closely related to temperature changes, such as drowning, falls, traffic, and suicides injuries, in order to reduce injury deaths associated with climate change.

Degenerative cervical spondylosis is a common spinal disorder in the elderly. During its progression, structural changes such as intervertebral disc degeneration, vertebral osteophyte formation, and facet joint degeneration directly impact neural structures, resulting in neuropathic pain. Moreover, the release of inflammatory mediators can further exacerbate pain, and increased neuronal excitability is considered one of the key pathological mechanisms of neuropathic pain. Current diagnostic and assessment methods for neuropathic pain associated with degenerative cervical spondylosis include clinical evaluation, imaging techniques (such as X-ray, computed tomography, and magnetic resonance imaging), and neurophysiological examinations (including electromyography and nerve conduction studies). Treatment options primarily involve pharmacological therapy, physical therapy, and surgical intervention, which have shown promising short-term outcomes. Despite progress made through the combined use of various treatment modalities, their long-term efficacy and safety remain to be further investigated. Personalized and multimodal treatment strategies are essential for improving patients' quality of life. Future research should continue to explore pain mechanisms and develop innovative therapeutic techniques to optimize clinical management.

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020， the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS， and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time， a nested case-control study （the ratio of trial group and control group was 1∶4） was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients， 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection， with the incidence of 0.076%. There was no serious adverse event， and the occurrence time was 2 days after medication； adverse drug events mainly include elevated liver function indicators （alanine transaminase， aspartate transaminase， total bilirubin）， which were mild and untreated， and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.

Objective To revalue the post-marketing safety of Xiyanping injection. Methods The research was carried out by prospective hospital based monitoring method. The leading organizations were Guangdong Medicine Adverse Reaction Monitoring Center and Chinese of Basic Research in Clinical Medicine Institute. The participants were 21 hospitals in 6 provinces/municipality directly under the Central Government which located in Northeast China,Central China,South China,and Southwest China. Monitoring objects were all patients who used Xiyanping injection when they were hospitalized. The set sample size was not fewer than 30 000 cases. Every patient who used Xiyanping injection filled in Xiyanping injection screening card(screening card)by research staff manually. The patient who developed adverse reactions(ADR)after using Xiyanping injection filled in Xiyanping injection monitoring table(monitoring table)by clinical pharmacist manually. All the hospital should report the screening card and the monitoring table to Guangdong Provincial Drug Reevaluation Report Management System(Reevaluation Report Management System)every month.The monitoring study ended when the number of screening cardrunning up to 30 000. The reported data were collected and the incidence rate of Xiyanping injection were calculated. The clinical characteristics of adverse reactions were analyzed. Results Data were collected through the Reevaluation Report Management System till January 23,2015. The monitoring study ended. Five hospitals stopped participation in the monitoring study because of discontinuity of cases′ data from March to August, 2013. A total of 30 759 screening cards and 23 monitoring tables which were from 16 hostipals were collected finally. There were 18 295(59.48%)male and 12 464(40.52%)female in 30 759 patients. Of them the number of patients whose age <4 years were 16 501(53.64%). The patients′primary diseases were mainly respiratory disease,infectious disease,parasitic disease,and digestive system disease. All the patients used Xiyanping injection with standard doses according to the instructions. Two thousands and eight hundred-ten (9.02%)patients did not use prescriptive menstruums. There were 28 353 patients(90.98%)who were treated with combined drugs at the same time. The top 4 combined drugs were antimicrobial agents, electrolyte acid-base balance and nutrition drugs,respiratory system drugs,and digestive system drugs successively. Twenty-three of 30 759 patients developed ADR related to Xiyanping injection,the ADR incidence rate was 0.75‰,95% confidence interval(CI)was 0.47‰ to 1.12‰. The results of deciding the relevance of ADR with Xiyanping injection as "in all probability","possible" and "unable to judge"were 12(51.27%),10(43.48%)and 1(4.35%)cases,respectively. Thirty-four ADR soccurred in 23 patients.The main clinical manifestations of ADR were erythra(19 cases),pruritus(7 cases),shiver with cold(4 cases),fever(3 cases),and cyanotic lips(1 case). The degree of adverse reactions were all general.Nineteen patients improved or recurred on the same day of drug withdrawal and treatment of antianaphylaxis. Three patients improved or recured within 2 days. One patient improved on the day 14 of drug withdrawal and treatment of antianaphylaxis.
