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 investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To explore the eradication rate of human papillomavirus(HPV)and gestational outcome of patients with high-grade squamous intraepithelial disease of the cervix(HSIL)after loop electrosurgical excision procedure(LEEP)by transvaginal dissection of the vesicorectal form the cervix.Methods A total of 53 patients treated with LEEP by transvaginal dissection of the vesicorectal form the cervix in Obstetrics and Gynecology Hospital,Fudan University from Jan to Dec,2019 were investigated.Clinical information of cervical cytological examination,HPV test and cervical biopsy under colposcopy were followed up for 6,12 and 24 months post-LEEP were collected.HPV infection in these 53 patients were compared before and after LEEP surgery.The rate of successful fertility of the cohort,the HPV conversion rate of patients with hysterectomy and LEEP done were compared.The association between the pathological type and positive surgical margin and the association between HPV infection type and positive surgical margin were analyzed.Results HPV infection rate of was 94.3%(50/53)and the proportion of HPV16 and/or 18 infection was 75.5%(40/53).Mono-HPV infection rate(69.8%,37/53)was significantly higher than mixed HPV infection rate(22.7%,13/53).Thirty-eight patients(71.7%)were found with positive surgical margin in previous LEEP operation.Fifteen patients had recurrence(28.3%)and 40 patients(75.5%)successfully delivered baby after surgery.Postoperative pathology was mainly HSIL,accounting for 66%(30/53),and 28.3%patients(15/53)had no pathological change.Forty cases had satisfying fertility-conservative operation outcome with negative surgical margin,and 38 patients eradicated HPV infection after LEEP,which took up 95%of patients with satisfying fertility-conservative operation.There was no significant difference of positive resection margin rate in between groups of HPV16/18 infection and other types.Five cases had successful delivery(12.5%,5/40)with 1 case of vaginal delivery and 4 cases of cesarean section.Among these 5 cases,3 cases undertook preventive cervical cerclage,with 1 case of vaginal delivery and 2 cases of cesarean sections.Conclusion HPV eradication rate and surgical outcome could be significantly improved by LEEP with transvaginal dissection of the vesicorectal from the cervix,which satisfied the fertility preservation of females at reproductive age.

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.

Objective To study the effect of panatinib on cholangiocarcinoma(CCA)and its molecular mechanism.Methods QBC939 cells were divided into control group(no treatment),low dose group(0.1 μmol·L-1 panatinib treatment),medium dose group(0.5μmol·L-1panatinib treatment),high dose group(1.0 μmol·L-1 panatinib treatment)and high dose+microRNA-92b-3 group(after treatment with 1.0 μmol·L-1 panatinib transfected miR-92b-3p mimic),high-dose+miR-92b-3p mimic+overexpressed homologous domain interacting protein kinase 3 plasmid(oe-HIPK3)group(after treatment with 1.0 μmol·L-1 panatinib,miR-92b-3p mimic and oe-HIPK3),mimic-NC group(transfected miR-92b-3p NC),and miR-92b-3p mimic group(transfected miR-92b-3p mimic)were transfected.Cell proliferation was detected by cell counting kit 8(CCK-8);cell migration was detected by Transwell,the relative expression level of protein was detected by Western blot.Results Cell proliferation rates of control group,high-dose group,high-dose+miR-92b-3p mimic group,and high-dose+miR-92b-3p mimic group mimic+oe-HIPK3 group were(76.58±8.56)％,(61.85±7.77)％,(74.54±7.68)％and(58.63±6.87)％,respectively;the number of cells migrated were 185.32±20.14,132.33±18.99,168.23±19.85 and 138.66±15.95,respectively;phosphorylated phosphatidyl inositide 3-kinase(p-PI3K)/PI3K ratios were 1.00±0.23,0.68±0.09,0.91±0.18 and 0.60±0.08,respectively;phosphorylated protein kinase B(p-AKT)/AKT ratios were 1.00±0.25,0.61±0.08,1.12±0.28 and 0.72±0.14,respectively.The above indexes were compared with those of the control group in the high-dose group,and those of the high-dose+miR-92b-3p mimic group in the high-dose+miR-92b-3p mimic group in the oe-HIPK3 group.There were statistically significant differences(all P＜0.05).Conclusion Panatinib can effectively inhibit the evil biological behavior of cholangiocarcinoma,which may be related to inhibiting the level of miR-92b-3p and promoting HIPK3-mediated PI3K/AKT signaling pathway.

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.
