Background Air pollution remains a critical public health issue, with persistent exposure to air pollutants continuing to pose significant health risks. Currently, research investigating the association between air pollution and myocardial infarction mortality in Shenzhen remains inadequate. Objective To quantitatively assess the association between air pollutants and myocardial infarction mortality in residents. Methods Based on the mortality surveillance system of Shenzhen Center for Disease Control and Prevention, we conducted a time-stratified case-crossover study of 10089 permanent residents who died from myocardial infarction in Shenzhen between 2013 and 2022. Using residential address information, we obtained individual-level exposure data for air pollutants from the China High Air Pollutants dataset and meteorological factors from the China Meteorological Administration Land Data Assimilation System. A time-stratified case-crossover study design was employed to construct a conditional logistic regression model to assess the association between short-term exposure to air pollutants and myocardial infarction mortality. The exposure-response relationship was visualized, and a comprehensive health risk assessment was performed. Results This study included a total of 10 089 cases of myocardial infarction deaths in Shenzhen. The median [interquartile range (IQR)] concentrations of fine particulate matter (PM_2.5), inhalable particulate matter (PM₁₀), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and ozone (O₃) in Shenzhen from 2013 to 2022 were 24.59 (20.19) μg·m⁻³, 42.85 (28.42) μg·m⁻³, 8.53 (3.39) μg·m⁻³, 29.47 (13.56) μg·m⁻³, 0.77 (0.27) mg·m⁻³, and 86.53 (51.39) μg·m⁻³, respectively. The moving average concentrations of PM_2.5 and PM₁₀ over the current day and the previous 2 days (lag02) showed the highest risk of myocardial infarction mortality, with an odds ratio (OR) and 95% confidence interval (95%CI) of 1.004 (1.001, 1.007) and 1.004 (1.002, 1.006), respectively. At lag05, SO₂ demonstrated the strongest association with the risk of myocardial infarction mortality, with an OR (95%CI) of 1.042 (1.019, 1.065). The exposure-response relationships of PM_2.5, PM₁₀, and SO₂ with myocardial infarction mortality were approximately linear, whereas NO₂ exhibited a nonlinear relationship. At lag05, the highest risk of myocardial infarction mortality associated with NO₂ exposure was observed when the NO₂ concentration was ≤21.92 μg·m⁻³, with an OR (95% CI) of 1.024 (1.003, 1.046). The health risk assessment indicated that, using the WHO Air Quality Guidelines as the reference, the local PM_2.5 and NO₂ exposure led to an excess mortality of 398 and 298 cases, respectively. The sensitivity analysis revealed that after adjusting for O₃ and restricting the study period to 2013—2019, the effect estimates for PM_2.5, PM₁₀, NO₂, and SO₂ on myocardial infarction mortality slightly increased. Conclusion Short-term exposure to air pollutants, including PM_2.5, PM₁₀, NO₂, and SO₂, could increase the risk of myocardial infarction mortality. This study provides important scientific evidence for environmental health risk assessment and environmental management in Shenzhen.

Objective To observe the efficacy of Hongjin Xiaojie capsules in treating hematoma after Mammotome minimally invasive excision and to determine the common clinical complications such as hematoma and pain after the surgery.Methods A total of 70 patients who developed hematoma within 72 hours after Mammotome minimally invasive excision for breast lumps at our hospital were selected.Based on different treatment methods,patients were divided into the observation group and the control group,with 35 cases in each group.The control group received only external hot compress treatment,while the observation group received local hot compress combined with oral administration of Hongjin Xiaojie Capsule for 4 weeks.Follow-up was conducted every 4 weeks postoperatively for a total of 12 weeks.Color ultrasound was performed to monitor the size of the hematoma.Changes in pain visual analog scale(VAS)scores and traditional Chinese medicine(TCM)syndrome scores for blood stasis were compared between the two groups of patients during follow-up.Results Four weeks after operation,the pain VAS score was significantly lower in the observation group than that in the control group[2(1,3)points vs.3(2,4)points,P＜0.05],and the proportion of hematoma was lower in the observation group than that in the control group(45.7%vs.82.9%,P＜0.05).At 12 weeks after surgery,there were no significant differences in pain scores or hematoma proportions between the two groups.The TCM symptom scores were lower in the observation group than those of the control group at 4 weeks and 12 weeks after operation(P＜0.05).Conclusion Hongjin Xiaojie capsule can promote the absorption of hematoma after Mammotome surgery,effectively alleviate breast hematoma and pain,and have high safety,demonstrating broad clinical application value.

Loss-of-function variants in CSDE1 have been strongly linked to neuropsychiatric disorders, yet the precise role of CSDE1 in neurogenesis remains elusive. In this study, we demonstrate that knockout of Csde1 during cortical development in mice results in impaired neural progenitor proliferation, leading to abnormal cortical lamination and embryonic lethality. Transcriptomic analysis revealed that Csde1 upregulates the transcription of genes involved in the cell cycle network. Applying a dual thymidine-labelling approach, we further revealed prolonged cell cycle durations of neuronal progenitors in Csde1-knockout mice, with a notable extension of the G1 phase. Intersection with CLIP-seq data demonstrated that Csde1 binds to the 3' untranslated region (UTR) of mRNA transcripts encoding cell cycle genes. Particularly, we uncovered that Csde1 directly binds to the 3' UTR of mRNA transcripts encoding Cdk6, a pivotal gene in regulating the transition from the G1 to S phases of the cell cycle, thereby maintaining its stability. Collectively, this study elucidates Csde1 as a novel regulator of Cdk6, sheds new light on its critical roles in orchestrating brain development, and underscores how mutations in Csde1 may contribute to the pathogenesis of neuropsychiatric disorders.

AIM: To study the effect of intense pulsed light(IPL)combined with meibomian gland massage on postoperative dry eye in cataract patients with meibomian gland dysfunction(MGD).METHODS: A retrospective analysis was conducted on the general data of 100 patients(100 eyes)with cataract and postoperative dry eye syndrome accompanied by MGD treated in our hospital from June 2022 to June 2023. They were divided into a control group(n=50)and an observation group(n=50)according to different treatment methods, and received meibomian gland massage and meibomian gland massage combined with IPL treatment, respectively. The tear film break-up time(BUT), Schirmer I test(S I t), meibomian gland secretion score, ocular surface disease index(OSDI), ocular staining score(OSS), and treatment efficacy of the two groups of patients were compared before treatment and at 1 wk and 1 and 3 mo after treatment.RESULTS: The BUT and SIt in both groups after treatment were higher than those before treatment, while the secretion of meibomian gland, OSS score, and OSDI score were lower than those before treatment(all P<0.05); the observation group had higher levels of BUT and SIT at 1 wk, 1 and 3 mo compared to the control group(all P<0.05), and lower levels of meibomian gland secretion, OSS score, and OSDI score compared to the control group(all P<0.05); the effective rate of treatment in the observation group was 86.0%, which was higher than that in the control group(68.0%; P<0.05).CONCLUSION: IPL combined with meibomian gland massage for treating postoperative dry eye in cataract patients with MGD can promote the extension of BUT, increase tear secretion, and reduce OSS and OSDI scores.

ObjectiveTo systematically analyze the typical mental health conditions and psychological disorders of children with intellectual and developmental disabilities (IDD), to construct a mental health service system and psychological interventions to these mental health conditions of children with IDD . MethodsBased on the framework of the World Health Organization Family International Classifications (WHO-FICs), the mental health conditions and related functioning were analyzed, and the mental health service framework and proposed mental health interventions were constructed.There were six main categories of mental health conditions for children with IDDConclusionThis study systematically analyzed the typical mental health status and related psychological functional impairments of children with IDD. Based on the World Health Organization health service system, a mental health service framework for children with IDD was constructed. Referring to the WHO's continuum of health services, a system of psychological intervention methods for children with IDD was established. Furthermore, the WHO-FICs were used to describe and code the functions of children with IDD, and the ICHI-β3 was applied to code and analyze the related psychological interventions. Resultsmood disorders (anxiety and depression), behavioral disorders (disruptive disorders and challenging behaviors, aggressive behaviors), traumatic disorders (post-traumatic stress disorder), mental disorders (schizophrenia), suicide and self-harm, and learning disabilities (developmental learning disabilities, attention deficit hyperactivity disorder). Mental health services for children with IDD involved in six dimensions: leadership and governance, fundraising, human resources, service delivery, mental health technologies, and information and research. Mental health services went through the continuum of health services from prevention, treatment, rehabilitation to health promotion. We delivered mental health services for children with IDD in three aspects: identifying and diagnosing mental health problems or conditions, analyzing the main factors caused mental health problems, and analyzing the environmental factors. Mental health service interventions mainly covered five categories: antidepressants, psychotherapy, stress management training, physical exercise training, healthy lifestyle education, consultation and support. Children with IDD may obtain the mental health services in hospitals, rehabilitation institutions, community and school settings.

Objective:To investigate acute adverse events and pregnancy outcome after vaccination of inactivated COVID-19 vaccine in the first trimester of pregnancy.Methods:The retrospective-prospective cohort study was conducted among pregnant women of 11-13 +6 weeks of gestation who visited the obstetric clinics for prenatal check in Lianyungang Maternal and Child Health Hospital from May to November in 2021, after registration for perinatal health cards in the community. Those who met the inclusion criteria were recruited and were divided into vaccination group and non-vaccination group according to whether they received inactivated COVID-19 vaccine in the first trimester. Women in the vaccination group were further divided into 1-dose group and 2-dose group. Information, including pregnancy-related screening, pregnancy complications, pregnancy outcome and acute adverse events, were collected and compared with independent samples t-test or ANOVA, Kruskal- Wallis H test or Mann-Whitney U test, χ2 test or Fisher's exact probability method. Results:Totally, 105 pregnant women were analyzed in 1-dose group, 90 in 2-dose group, and 194 in non-vaccination group. (1) There were no statistically significant differences in the occurrence of acute adverse events [1-dose group: 2.86% (3/105); 2-dose group: 6.67% (6/90); non-vaccination group: 4.63% (9/194); χ2=1.59; vaccination group was 4.61% (9/195), when compared with non-vaccination group, χ2=0.00], abnormal pregnancy-related screening indicators and abnormal pregnancy outcome among the three groups (all P>0.05), neither between the vaccination and non-vaccination group (all P>0.05). The acute adverse events in these women included fever, pain at the inoculation site, fatigue, local induration and rash.(2) The differences in hypertensive disorders in pregnancy among the three groups were statistically significant [1-dose group: 10.5%(11/105); 2-dose group: 17.8%(16/90); non-vaccination group: 7.7%(15/194); χ2=6.46, P=0.040], and the incidence was higher in the 2-dose group than that in the non-vaccination group (adjusted by Bonferroni, P<0.017). (3) Regarding other pregnancy complications, no difference was found among the three groups (all P>0.05), neither between the vaccination and non-vaccination group (all P>0.05). Conclusion:The risk of acute adverse events and adverse pregnancy outcome is similar in pregnant women who received inactivated COVID-19 vaccine versus those who did not in the first trimester, and regular blood pressure monitoring is recommended for those who received two doses of inactivated COVID-19 vaccine.
