ObjectiveTo study the pharmacological substances and mechanisms through which sesquiterpene ZH-13 from Aquilariae Lignum Resinatum improves neuroinflammation. MethodsBV-2 microglial cells were stimulated with lipopolysaccharide (LPS) to induce neuroinflammation. The cells were divided into the normal group, the model group, and the ZH-13 low- and high-dose treatment groups (10, 20 μmol·L-1). The model group was treated with 1 μmol·L-1 LPS. Cell viability was assessed using the cell proliferation and activity assay (CCK-8 kit). Nitric oxide (NO) release in the cell supernatant was measured using a nitric oxide kit (Griess method). The mRNA expression levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), and interleukin-6 (IL-6) were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The phosphorylation of mitogen-activated protein kinase (MAPK) pathway proteins was assessed by Western blot. ResultsCompared with the model group, ZH-13 dose-dependently reduced NO release from BV-2 cells under LPS stimulation (P<0.05, P<0.01). In the 20 μmol·L-1 ZH-13 treatment group, the mRNA expression levels of IL-1β, TNF-α, iNOS, and IL-6 were significantly reduced compared to the model group (P<0.05, P<0.01). In both the low- and high-dose ZH-13 groups, the expression of the inflammatory factor TNF-α and the phosphorylation of c-Jun N-terminal kinase (JNK) in the upstream MAPK pathway were significantly reduced (P<0.05). After stimulation with the JNK agonist anisomycin (Ani), both low- and high-dose ZH-13 treatment groups showed reduced phosphorylation of JNK proteins compared to the Ani-treated group (P<0.01). ConclusionThe sesquiterpene compound ZH-13 from Aquilariae Lignum Resinatum significantly ameliorates LPS-induced neuroinflammatory responses in BV-2 cells by inhibiting excessive JNK phosphorylation and reducing TNF-α expression. These findings elucidate the pharmacological substances and mechanisms underlying the sedative and calming effects of Aquilariae Lignum Resinatum.

Objective:
To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures.
Methods:
Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC).
Results:
A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively.
Conclusions
The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Objective:
To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children.
Methods:
Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model.
Results:
Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats.
Conclusions
Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

There are millions of patients with taxane-induced peripheral neuropathy (TIPN), and there is no effective treatment or prevention measure in clinical practice. The occurrence of TIPN may be related to the dosage form of paclitaxel drugs, genetic and molecular markers, drug dosage and chemotherapy cycle, patient factors, etc. At present, drugs for treating TIPN mainly include those that inhibit axonal degeneration (such as dosazosin, tamsulosin), prevent mitochondrial dysfunction (such as glutathione trisulfides, antioxidants α -lipoic acid), improve calcium imbalance in the internal environment (Shaoyao gancao decoction, N-type voltage-gated calcium channel inhibitor IPPQ), and inhibit neuroinflammation (such as chemokine inhibitors and selective interleukin-8 receptor inhibitors DF2726A). Further exploration of drug treatment strategies targeting different induction mechanisms is expected to become a new direction for precise clinical prevention and personalized treatment of TIPN.

Oral squamous cell carcinoma (OSCC) is a prevalent malignant tumor affecting the head and neck region (Leemans et al., 2018). It is often diagnosed at a later stage, leading to a poor prognosis (Muzaffar et al., 2021; Li et al., 2023). Despite advances in OSCC treatment, the overall 5-year survival rate of OSCC patients remains alarmingly low, falling below 50% (Jehn et al., 2019; Johnson et al., 2020). According to statistics, only 50% of patients with oral cancer can be treated with surgery. Once discovered, it is more frequently at an advanced stage. In addition, owing to the aggressively invasive and metastatic characteristics of OSCC, most patients die within one year of diagnosis. Hence, the pursuit of novel therapeutic drugs and treatments to improve the response of oral cancer to medication, along with a deeper understanding of their effects, remains crucial objectives in oral cancer research (Johnson et al., 2020; Bhat et al., 2021; Chen et al., 2023; Ruffin et al., 2023).

Purpose:
This study aims to comprehensively evaluate the clinical efficacy of chemotherapy or endocrine therapy maintenance in metastatic breast cancer (MBC) patients.
Materials and Methods:
The meta-analysis of randomized clinical trials (RCTs) and propensity score matching of multicenter cohort study evaluated MBC patients who underwent first-line chemotherapy or endocrine therapy maintenance. This study is registered with PROSPERO: CRD42017071858 and ClinicalTrials.gov: NCT04258163.
Results:
A total of 2,867 patients from 15 RCTs and 760 patients from multicenter cohort were included. The results from meta-analysis showed that chemotherapy maintenance improved progression-free survival (PFS) (hazard ratio [HR], 0.63; 95% confidence interval [CI], 0.54 to 0.73; p < 0.001; moderate-quality evidence) and overall survival (OS) (HR, 0.87; 95% CI 0.78 to 0.97; p=0.016; high-quality evidence) than observation. In the cohort study, for hormone receptor–positive MBC patients, chemotherapy maintenance improved PFS (HR, 0.67; 95% CI, 0.52 to 0.85; p < 0.001) and OS (HR, 0.55; 95% CI 0.42 to 0.73; p < 0.001) compared with observation, and endocrine therapy maintenance also improved PFS (HR, 0.65; 95% CI, 0.53 to 0.80; p < 0.001) and OS (HR, 0.55; 95% CI, 0.44 to 0.69; p < 0.001). There were no differences between chemotherapy and endocrine therapy maintenance in PFS and OS (all p > 0.05). Regardless of the continuum or switch maintenance therapy, showed prolonged survival in MBC patients who were response to first-line treatment.
Conclusion
This study provided evidences for survival benefits of chemotherapy and endocrine therapy maintenance in MBC patients, and there was no difference efficacy between chemotherapy and endocrine therapy maintenance for hormone receptor–positive patients.

Objective:To compare the safety and efficacy of medial-lateral pinning (MLP) and lateral pinning (LP) in pediatric supracondylar humeral fractures.Methods:According to PRISMA procedure, the randomized controlled trial (RCT) of pediatric supracondylar humeral fractures in PubMed (Medline), EMBASE, the Cochrane Library databases (Cochrane Controlled Trials Register for RCTs) and Wanfang Data from 1 January, 1990 to 1 January, 2020 were retrieved. Two researchers independently extracted the data and evaluated the quality of the original studies; the random-effects model was used for analysis.Results:A total of 4 679 original literatures were retrieved and 11 literatures were finally included, involving 920 children. Meta analysis results showed that there were no statistical differences in excellent ratio of elbow joint function (Flynn criteria), incidence of iatrogenic nerve injury and incidence of pin tract/ superficial infection between MLP group and LP group: 74.3% (255/343) vs. 72.9% (250/343), 6.1% (16/262) vs. 1.6% (4/246) and 5.3% (14/264) vs. 7.6% (20/262); RR = 0.98, 0.43 and 1.31; 95% CI 0.90 to 1.07, 0.18 to 1.03 and 0.64 to 2.67, P>0.05; the incidence of reduction loss in MLP group was significantly lower than that in LP group: 16.6% (51/307) vs. 23.9% (72/301), and there was statistical difference ( RR = 1.39, 95% CI 1.02 to 1.89, P = 0.04). Conclusions:MLP fixation and LP fixation are equally efficacious for supracondylar humeral fractures in children. MLP fixation may reduce the risk of reduction loss without increasing the risk of iatrogenic nerve injury. Manual reduction and MLP percutaneous Kirschner wire fixation for the treatment of displaced supracondylar humeral fractures in children is recommended.
