OBJECTIVE:
Cancer remains a significant global health challenge, necessitating the development of effective treatment approaches. Developing synergistic therapy can provide a highly promising strategy for anti-cancer treatment through combining the benefits of various mechanisms.
METHODS:
In this study, we developed a synergistic strategy for chemo-photothermal therapy by constructing nanocomposites using gold nanorods (GNRs) and tetrahedral framework nucleic acids (tFNA) loaded with the anti-tumor drug doxorubicin (DOX).
RESULTS:
Our in vitro studies have systematically clarified the anti-cancer behaviors of tFNA-DOX@GNR nanocomposites, characterized by their enhanced cellular uptake and proficient lysosomal escape capabilities. It was found that the key role of tFNA-DOX@GNR nanocomposites in tumor ablation is primarily due to their capacity to induce cytotoxicity in tumor cells via a photothermal effect, which generates instantaneous high temperatures. This mechanism introduces various responses in tumor cells, facilitated by the thermal effect and the integrated chemotherapeutic action of DOX. These reactions include the induction of endoplasmic reticulum stress, characterized by elevated reactive oxygen species levels, the promotion of apoptotic cell death, and the suppression of tumor cell proliferation.
CONCLUSION
This work exhibits the potential of synergistic therapy utilizing nanocomposites for cancer treatment and offers a promising avenue for future therapeutic strategies.

Objective To evaluate the value of pre-ascent 6-minute walking test performed at a high altitude in predicting the incidence of acute mountain sickness(AMS)induced by rapid ascent to a very high altitude.Methods After baseline information was collected,participants completed the 6-minute walking test at a high altitude of 2 900 m.Then,they rapidly ascended to a very high altitude of 5 000 m.The Lake Louise score was recorded to assess AMS.Results The AMS group showed a shorter pre-ascent 6-minute walking distance(6MWD)at the high altitude than the non-AMS group[480.00(450.00,521.75)m vs.546.00(516.50,568.50)m,P=0.006].No difference was observed regarding the pre-ascent heart rate or peripheral oxygen saturation(both P>0.05).The pre-ascent 6MWD at the high altitude was negatively correlated with the Lake Louise score assessed after rapid ascent to the very high altitude(r=-0.497,P=0.012).Logistic regression analysis confirmed that the pre-ascent 6MWD at the high altitude was associated with the risk of AMS induced by rapid ascent to the very high altitude(OR=0.971,95% CI=0.947-0.996,P=0.022).The results indicated that the pre-ascent 6MWD demonstrated ideal prediction performance(area under receiver operating characteristic curve=0.846,P=0.006).Conclusion The pre-ascent 6MWD recorded at the high altitude is a convenient and reliable predictor of the AMS induced by rapid ascent to the very high altitude.

In the context of delayed marriage and parenthood, decreased willingness in having children, and population aging in China, maternal and child health has become an important and urgent issue. Being essential platforms for research in maternal and child health, the importance of birth cohorts has been widely recognized. In the past 20 years, tens of birth cohorts have been established in major cities and regions of China, with cohorts ranging from thousands to hundreds of thousands. These cohorts, particularly those large ones launched in recent years, have collected a wide spectrum of data and biological samples from mothers and children. Although they have made considerable preliminary achievements, there remain difficulties and challenges. The significant challenges include small and medium-sized cohorts' lacking of clear research themes; insufficient recognition of and emphasis on behavioral and social determinants of health while emphasizing biological determinants of health; variations in types of variables and quality of data collected, which make it difficult for cohorts to be merged and shared; lack of and difficulties in long-term follow-up; significant uncertainties in resources for long-term sustention of the cohorts, and so on. So, we argue that birth cohorts should focus on essential and urgent issues in maternal and child health in the country and seek recognition and support from the government and the entire society. Last but not least, the overall success of birth cohorts in the country requires scientists to be not only academically capable, but also realistic, persistent, altruistic, and collaborative.

DNA polymerase theta (Polθ), also known as DNA polymerase θ, is the member of the DNA polymerase A family and plays a crucial role in the repair of DNA double-strand breaks (DSB). Polθ has 3 distinct structural domains: the N-terminal helicase-like domain with a conserved sequence, the C-terminal polymerase domain, and the central domain, which is a disordered sequence connecting these two regions. Notably, Polθ is the only known polymerase in eukaryotes that possesses helicase activity. However, it is also an error-prone polymerase. When DNA DSBs occur, a specialized network consisting of at least 4 pathways, including classical-non homologous end joining (C-NHEJ), homologous recombination (HR), single-strand annealing (SSA), and alternative-end joining (Alt-EJ), is responsible for repairing DNA damage caused by DSBs. In the absence of major DNA repair pathways like HR, cells rely on Alt-EJ pathway mediated by Polθ to repair damaged DNA and maintain genomic stability. Nevertheless, due to the low fidelity of Polθ, Alt-EJ repair often leads to errors. Depletion of Polθ has shown to increases DSB formation and compromise genomic stability. Conversely, overexpression of Polθ has been associated with increases DNA damage markers and impairs cell cycle progression. As a result, the impact of Polθ on genome stability remains controversial. Furthermore, overexpression of Polθ is frequently observed in cancer and is associated with a characteristic mutational signature and poor prognosis. Depleting Polθ in an HR-deficient background has been shown to impair cell viability, suggesting a synthetic lethal (SL) relationship between Polθ and HR factors. In recent years, targeted chemotherapy drugs that inhibit tumor growth have gained significant attention. However, off-target effects and drug resistance pose challenges for clinical application, particularly with poly-ADP-ribose polymerase inhibitor (PARPi). Blocking Polθ activity in HR-deficient tumor cells has been found to reverse PARPi resistance, making Polθ a very promising therapeutic target in cancer treatment. The availability of crystal structures for both helicase and polymerase domain has facilitated the design of potent inhibitors of Polθ. Currently, several highly specific and effective small molecule inhibitors targeting Polθ, such as Novobiocin, RP-6685, and ART558, have been reported to effectively block various cancers with HR deficiency. The initial success of these inhibitors points to new directions for treating BRCA1/2-mutated tumors. Additionally, reducing the Alt-EJ repair pathway mediated by Polθ can improve HR repair efficiency and increase the chance of exogenous gene target integration (TI), suggesting potential new applications for Polθ inhibitors. This article reviews the recent research progress on the molecular function of Polθ and its involvement in the Alt-EJ pathway modification mechanism, providing insights for a deeper understanding of this field.

To explore the application value of endoscopic ultrasound fine-needle aspiration (EUS-FNA) and endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and treatment ofpatients with pancreatic cancer combined with obstructive jaundice. Clinical data of patients hospitalized in the Department of Gastroenterology of Peking Union Medical College Hospital who underwent ERCP biliary stent drainage for pancreatic cancer combined with obstructive jaundice from January 1, 2023 to February 26, 2024 were retrospectively collected. They were categorized into the fusion technology group and the simple ERCP group according to whether EUS-FNA was performed in the same endoscopic unit. The differences in pathologic diagnosis rate, ERCP drainage success rate, postoperative complication rate and patients' single hospitalization time were compared between the two groups. A total of 161 patients with pancreatic cancer combined with obstructive jaundice who underwent ERCP biliary stent drainage meeting the inclusion and exclusion criteria were enrolled, of which 80 were in the fusion technique group and 81 were in the simple ERCP group. The pathological diagnosis rate in the fusion technique group was higher than that in the simple ERCP group[92.50%(74/80) The fusion of EUS-FNA and ERCP enhances the efficiency of diagnosis and treatment for pancreatic carcinoma, warranting widespread adoption and further research.

Objective:To explore the independent risk factors for the occurrence and aggravation of lower back pain (LBP) in patients with Parkinson′s disease (PD), in order to provide reference for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the case data of 309 PD patients who visited the Affiliated Yixing Hospital of Jiangsu University from June 2018 to May 2020. The KING Parkinson′s Disease Pain Scale (KPPS) was used to quantitatively evaluate the LBP of PD patients, who were divided into LBP group and Non LBP group. The general clinical data, PD related data, and imaging data of the two groups were compared and analyzed. Binary logistic regression analysis was used to evaluate independent risk factors for LBP in PD patients. Pearson correlation analysis was conducted between KPPS scores and various factors, and linear regression analysis was used to identify the relevant risk factors that exacerbate LBP in PD patients.Results:Compared with the Non LBP group, the LBP group had lower bone mineral density (BMD) and a lower proportion of patients who engaged in daily exercise. The difference between the two groups was statistically significant (all P<0.05). Compared with the Non LBP group, patients in the LBP group had a longer course of illness, higher stiffness scores, a higher proportion of patients with fluctuating symptoms, higher UPDRS-Ⅲ scores, and a higher proportion of patients with thoracolumbar fascial injury (TLFI) and lumbar sagittal imbalance. The differences between the two groups were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that combined TLFI ( OR=2.773, 95% CI: 1.219-6.309, P=0.015), combined lumbar sagittal imbalance ( OR=4.835, 95% CI: 2.244-10.421, P<0.001), and lower BMD ( OR=2.818, 95% CI: 1.767-4.493, P<0.001) were risk factors for LBP in PD patients. The KPPS score was correlated with BMD and TLFI ( r=-0.146, 0.294, all P<0.05). The linear regression results showed that the merged TLFI ( B=2.271, β=0.285, P<0.001) was positively correlated with KPPS score, indicating a risk factor. Conclusions:The combination of TLFI, lumbar sagittal imbalance, and lower BMD is closely related to the occurrence of LBP in PD patients, and the combination of TLFI is an independent risk factor for exacerbating LBP symptoms. Clinical attention should be paid to the prevention and treatment of TLFI in PD patients.

Objective:To assess the efficacy of endoscopic transmural drainage, transpapillary drainage and their combination in reducing cyst recurrence in patients with disconnected pancreatic duct syndrome (DPDS).Methods:A retrospective study was conducted involving 22 patients diagnosed as having DPDS in Peking Union Medical College Hospital from January 2018 to December 2022. Patient data including clinical information, imaging characteristics, drainage technique, complications, and outcomes were extracted from the medical records and telephone follow-up.Results:There were 27 endoscopic treatments in 22 patients, which were categorized into 3 groups based on the procedural approach: transmural in 11 cases, transpapillary in 8, and the combination of both in 8. The combined drainage group exhibited a significantly higher drainage success rate (100.0%, 8/8) compared with the transpapillary group (50.0%, 4/8, P=0.012), with no significant difference compared with the transmural group [90.9% (10/11), P=0.621]. The one-year recurrence rate was significantly lower in the combined drainage group [0.0% (0/8)] than that in the transmural drainage group [55.6% (5/9), P=0.018], and transpapillary drainage alone [42.9% (3/7)] though it did not reach significance ( P=0.085). No significant differences were observed in treatment success rate [45.5% (5/11), 75.0% (6/8) and 87.5% (7/8), H=3.890, P=0.143], or complication incidence [54.5% (6/11), 75.0% (6/8) and 25.0% (2/8), H=3.909, P=0.142]. Conclusion:Transmural drainage combined with pancreatic duct stent placement results in satisfactory drainage of cystic fluid in the short term and significantly reduces one-year recurrence among patients with DPDS.
