OBJECTIVE: To observe the clinical efficacy of Qihuang needle therapy for autism spectrum disorder (ASD) children with sleep disorder. METHODS: A total of 60 ASD children with sleep disorder were randomly divided into an observation group and a control group, 30 cases in each group. Both groups were treated with structured education intervention, 60 min each time, once a day, 6 times a week. Qihuang needle therapy was applied at Yintang (GV24⁺), Baihui (GV20) and bilateral Jueyinshu (BL14), Xinshu (BL15) in the observation group, multi-direction needling was delivered and without needle retaining. The treatment was given 2 times a week, each treatment was delivered at interval of 2 days at least. Behavioral intervention was adopted in the control group. Treatment for consecutive 12 weeks was required in both groups. Before and after treatment, the scores of children's sleep habits questionnaire (CSHQ), the autism behavior checklist (ABC), the childhood autism rating scale (CARS), and the childhood autism behavior scale (CABS) were observed in the two groups. RESULTS: After treatment, the scores of CSHQ, ABC, CARS and CABS were decreased compared with those before treatment (P<0.01), and the above scores in the observation group were lower than those in the control group (P<0.05). CONCLUSION Qihuang needle therapy can effectively treat ASD with sleep disorder, improve the core symptoms of ASD and the sleep quality.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

To improve the quality evaluation system of Hibisci Mutabilis Folium, this study established high performance liquid chromatography(HPLC) fingerprints of Hibisci Mutabilis Folium and evaluated the quality differences of medicinal materials from different places of production by chemometrics. Furthermore, a content measurement method of differential components was established based on quantitative analysis of multi-components by single-marker(QAMS). The fingerprints of 17 batches of Hibisci Mutabilis Folium from different places of production were constructed, with a total of 19 common peaks marked and seven components confirmed. The similarity between the sample fingerprints and the reference fingerprints ranged from 0.890 to 0.974. By utilizing principal component analysis(PCA), hierarchical cluster analysis(HCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA), the chemical patterns of fingerprints were identified. Five components that could be used to evaluate the quality differences of Hibisci Mutabilis Folium were screened, namely peak 6(quercetin 3-O-β-robinobioside), peak 7(rutin), peak 9(kaempferol-3-O-β-robinobioside), peak 10(kaempferol-3-O-rutinoside), and peak 14(tiliroside). The relative correction factors of isoquercitrin, kaempferol-3-O-β-robinobioside, kaempferol-3-O-rutinoside, kaempferol-3-O-β-D-glucoside, and tiliroside were measured with rutin as the internal reference. The QAMS method was established for the content measurement of six flavonoids, and the results showed there was no significant difference compared to the results obtained by an external standard method. In summary, the HPLC fingerprints and QAMS method established in the study, demonstrating stability and accuracy, can provide a reference for the overall quality evaluation of Hibisci Mutabilis Folium.

Spermatogenesis is a fundamental process that requires a tightly controlled epigenetic event in spermatogonial stem cells (SSCs). The mechanisms underlying the transition from SSCs to sperm are largely unknown. Most studies utilize gene knockout mice to explain the mechanisms. However, the production of genetically engineered mice is costly and time-consuming. In this study, we presented a convenient research strategy using an RNA interference (RNAi) and testicular transplantation approach. Histone H3 lysine 9 (H3K9) methylation was dynamically regulated during spermatogenesis. As Jumonji domain-containing protein 1A (JMJD1A) and Jumonji domain-containing protein 2C (JMJD2C) demethylases catalyze histone H3 lysine 9 dimethylation (H3K9me2), we firstly analyzed the expression profile of the two demethylases and then investigated their function. Using the convenient research strategy, we showed that normal spermatogenesis is disrupted due to the downregulated expression of both demethylases. These results suggest that this strategy might be a simple and alternative approach for analyzing spermatogenesis relative to the gene knockout mice strategy.

Pyroptosis is an identified programmed cell death that has been highly linked to endoplasmic reticulum (ER) dynamics. However, the crucial proteins for modulating dynamic ER membrane curvature change that trigger pyroptosis are currently not well understood. In this study, a biotin-labeled chemical probe of potent pyroptosis inducer α-mangostin (α-MG) was synthesized. Through protein microarray analysis, reticulon-4 (RTN4/Nogo), a crucial regulator of ER membrane curvature, was identified as a target of α-MG. We observed that chemically induced proteasome degradation of RTN4 by α-MG through recruiting E3 ligase UBR5 significantly enhances the pyroptosis phenotype in cancer cells. Interestingly, the downregulation of RTN4 expression significantly facilitated a dynamic remodeling of ER membrane curvature through a transition from tubules to sheets, consequently leading to rapid fusion of the ER with the cell plasma membrane. In particular, the ER-to-plasma membrane fusion process is supported by the observed translocation of several crucial ER markers to the "bubble" structures of pyroptotic cells. Furthermore, α-MG-induced RTN4 knockdown leads to pyruvate kinase M2 (PKM2)-dependent conventional caspase-3/gasdermin E (GSDME) cleavages for pyroptosis progression. In vivo, we observed that chemical or genetic RTN4 knockdown significantly inhibited cancer cells growth, which further exhibited an antitumor immune response with anti-programmed death-1 (anti-PD-1). In translational research, RTN4 high expression was closely correlated with the tumor metastasis and death of patients. Taken together, RTN4 plays a fundamental role in inducing pyroptosis through the modulation of ER membrane curvature remodeling, thus representing a prospective druggable target for anticancer immunotherapy.

Pancreatic cancer (PC) is a highly fatal disease which originated from pancreatic epithelial and acinar cells, and the survival rate of pancreatic cancer patients is only about 12%. Approximately 95% of pancreatic cancer presents as ductal adenocarcinoma (PDAC). Pancreatic cancer is characterized by high aggressiveness, rapid progression and progression, and high resistance to treatment. Common somatic mutated genes in the early stage of pancreatic cancer include KRAS, CDKN2A, TP53, and SMAD4. Most pancreatic cancer patients are affected by environmental risk factors such as age, sex and diet. Malignant pancreatic cancer is associated with non-invasive, preneoplastic lesions that are thoughted to be precursors, such as pancreatic intraepithelial neoplasia (PanIN), intraductal papillary mucinous neoplasm (IPMN) and mucinous cystadenoma (MCN). In recent years, people have gradually improved the therapy and diagnosis of pancreatic cancer, and the contribution of imaging technology, which enhancing the usage of minimally invasive pancreatectomy that typically includes pancreaticoduodenectomy and distal pancreatectomy. However, combined administration of the chemotherapeutic gemcitabine and erlotinib is still considered a potential first-line treatment for advanced pancreatic cancer, but the development of chemoresistance often leads to poor therapeutic outcomes. Based on the current research progress for pancreatic cancer, its treatment currently remains one of the most important challenges in the medical field. Although some new treatment options have been provided, there were minor clinical success achieved and therefore new safe and effective therapies of pancreatic cancer are still an urgent need for patients. Among these new therapies for pancreatic cancer, short peptide-based treatment protocols have attracted great attention. Peptide is a compound formed by linking α-amino acids together in peptide chains. It is also an intermediate product of proteolysis. The short peptide-based therapy has many advantages such as precise targeting, easy preparation and low toxicity. Short peptides usually act as tumor suppressors by targeting and recognizing tumor-specific expressed proteins. Currently, there is an increased interest in peptides in pharmaceutical and development research, and approximate 140 peptide therapeutics are currently being evaluated in clinical trials. These peptides provide excellent prospects for targeted drug delivery because of their high selectivity, specificity and simplicity of modification. Peptides have high bioactivity and excellent biodegradability. Clinically, short peptides are increasingly used as combination drugs with chemotherapy for tumor treatment. Peptides can induce cancer cell death by numerous mechanisms and peptides have emerged as a promising drug for the treatment of pancreatic cancer. Here we mainly review the roles of peptides on Wnt/β-catenin, NF-κB, autophagy, and the use of peptides as tracer in pancreatic cancer. We also analyzed the benefits and disadvantages existing in the development process of short peptides, which provide the feasibility of targeted short peptides to become new therapeutic approaches for cancer therapy.

Objective:To explore the differences in tumor-specific growth factors, cellular immune function and efficacy of olaparib and platinum-containing regimen for treatment of platinum-sensitive relapsed ovarian cancer patients with BRCA mutation.Methods:A retrospective cohort study was conducted. A total of 100 platinum-sensitive relapsed BRCA-mutant ovarian cancer patients in Baoding Second Central Hospital from September 2017 to March 2020 were retrospectively selected. The clinical data of the patients were analyzed, and they were divided into the olaparib group (treated with olaparib tablets) and the platinum-containing regimen group (treated with paclitaxel and platinum drugs for 6 cycles, followed by olaparib tablets maintenance therapy), with 50 patients in each group. The clinical efficacy, tumor specific growth factor [carbohydrate antigen (CA) 125, CA199, human epididymal protein 4 (HE4)] levels, cellular immune function-related indicators [T-cell subsets (proportions of CD3 + cells and CD4 + cells), CD4 + cells/CD8 + cells ratio (CD4 +/CD8 +)], and quality of life scores before treatment and after 2, 4 and 6 cycles of treatment of the two groups were compared, as well as the safety of the two groups. The data of three years of follow-up were obtained, Kaplan-Meier method was used to analyze the progression-free survival (PFS) of patients in the two groups, and log-rank test was used for comparison between groups. Results:The age of patients in the olaparib and platinum-containing regimen groups was (53±7) years old and (56±7) years old, respectively. The differences in compositions of patients with different age, body mass index, Eastern Cooperative Oncology Group (ECOG) performance status score, primary tumor location, lesion size, pathological stage, pathological type, germline BRCA mutation, and previous chemotherapy response between the two groups were not statistically significant (all P > 0.05). The objective response rate (ORR) [58.0% (29/50) vs. 38.0% (19/50)] and disease control rate (DCR) [80.0% (40/50) vs. 56.0% (28/50)] of the olaparib group after treatment were higher than those of the platinum-containing regimen group, and the differences were statistically significant (both P < 0.05). Serum CA125, CA199 and HE4 levels were gradually decreased in both groups before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05); serum CA125, CA199 and HE4 levels in the olaparib group after 2, 4 and 6 cycles of treatment were lower than those in the platinum-containing regimen group, and the differences were statistically significant (all P < 0.05). The CD3 + cells ratio, CD4 + cell ratio and CD4 +/CD8 + in the olaparib group gradually increased before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05), while those in the platinum-containing regimen group all gradually decreased (all P < 0.05); the CD3 + cells ratio, CD4 + cells ratio and CD4 +/CD8 + in the olaparib group were higher than those in the platinum-containing regimen group after 2, 4 and 6 cycles of treatment, and the differences were statistically significant (all P < 0.05). The quality of life scores of both groups increased before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05), and the quality of life scores of the olaparib group were higher than those of the platinum-containing regimen group after 2, 4 and 6 cycles of treatment, and the differences were statistically significant (all P < 0.05). The incidence of nausea, fatigue and malaise, vomiting, anemia, and diarrhea at all levels in the olaparib group was lower than those in the platinum-containing regimen group (all P < 0.05). By follow-up for 3 years, there was no statistically significant difference in PFS between the olaparib group and the platinum-containing regimen group ( P > 0.05). Conclusions:The efficacy of olaparib treatment in platinum-sensitive relapsed ovarian cancer patients with BRCA mutation is superior to platinum-containing regimen, and it can increase the level of T cells, inhibit the expression of tumor-specific growth factors, improve the quality of life, and have a positive effect on improving the safety of treatment.

Polycystin-2 (also known as PC2, TRPP2, PKD2) is a major contributor to the underlying etiology of autosomal dominant polycystic kidney disease (ADPKD), which is the most prevalent monogenic kidney disease in the world. As a transient receptor potential (TRP) channel protein, PC2 exhibits cation-permeable, Ca²⁺-dependent channel properties, and plays a crucial role in maintaining normal Ca²⁺ signaling in systemic physiology, particularly in ADPKD chronic kidney disease. Structurally, PC2 protein consists of six transmembrane structural domains (S1-S6), a polycystin-specific “tetragonal opening for polycystins” (TOP) domain located between the S1 and S2 transmembrane structures, and cytoplasmic N- and C-termini. Although the cytoplasmic N-terminus and C-terminus of PC2 may not be significant in the gating of PC2 channels, there is still much protein structural information that needs to be thoroughly investigated, including the regulation of channel function and the assembly of homotetrameric ion channels. This is further supported by the presence of human disease-associated mutation sites on the PC2 structure. Moreover, PC2 synthesized in the endoplasmic reticulum is enriched in specific subcellular localization via membrane transport and can assemble itself into homotetrameric ion channels, as well as form heterotrimeric receptor-ion channel complexes with other proteins. These complexes are involved in a wide range of physiological functions, including the regulation of mechanosensation, cell polarity, cell proliferation, and apoptosis. In particular, PC2 assembles with chaperone proteins to form polycystic protein complexes that affect Ca²⁺ transport in cell membranes, cilia, endoplasmic reticulum, and mitochondria, and are involved in activating cell fate-related signaling pathways, particularly cell differentiation, proliferation, survival, and apoptosis, and more recently, autophagy. This leads to a shift of cystic cells from a normal uptake, quiescent state to a pathologically secreted, proliferative state. In conclusion, the complex structural and functional roles of PC2 highlight its critical importance in the pathogenesis of ADPKD, making it a promising target for therapeutic intervention.

Objective:To compare the short-term outcomes of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants supplementarily fed with fortified donor human milk (DHM) or preterm formula (PF) when the mother's own milk (MOM) is insufficient.Methods:This retrospective cohort study included 91 VLBW or ELBW preterm infants with birth weight<1 500 g who were hospitalized in Peking Union Medical College Hospital from October 1, 2017, to September 30, 2020. Based on the supplemental feeding method when MOM was insufficient, these infants were divided into the DHM group ( n=51) and PF group ( n=40). Mann-Whitney U, t-test, Chi-square test, or Fisher's exact test were used to compare the short-term clinical outcomes during hospitalization between the two groups. Results:(1) There were no statistically significant differences between the 91 preterm infants in the DHM group and PF group in their gestational age, birth weight, sex ratio, birth mode, mothers' age at delivery, or the proportion of infants of small gestational age (all P>0.05). (2) The feeding volume in the DHM group was significantly greater than that in the PF group on the 14th day after birth [(108.2±53.1) vs. (81.0±47.8) ml/(kg·d), t=0.78, P=0.020]. Moreover, the time to achieve the feeding amounts up to 120 ml/(kg·d) and 150 ml/(kg·d) for infants in the DHM group were significantly shorter than those in the PF group [(17.5±10.2) vs. (30.0±12.0) d, t=4.38; (22.1±13.3) vs. (32.3±11.9) d, t=0.02; both P<0.05]; (3) Lower proportion of peripherally inserted central catheter (PICC) [58.8% (30/51) vs. 100% (40/40), χ 2=21.88, P<0.001] and shorter PICC duration were observed in the DHM group [10.0 (0.0-19.0) vs. 29.0 (17.0-40.5) d, Z=5.56, P<0.001] compared to the PF group. The times of red blood cell transfusions and the incidence of late sepsis in the DHM group were less than those in the PF group [0.0 (0.0-2.0) vs. 2.0 (1.0-3.0) times, Z=4.44, P<0.001; 23.5% (12/51) vs. 50.0% (20/40), χ 2=6.39, P=0.011]. There were no statistically significant differences observed in the incidence of bronchopulmonary dysplasia, neonatal necrotizing enterocolitis, retinopathy of prematurity, and the length of hospitalization (all P>0.05). Conclusion:When MOM is insufficient, supplementing VLBW and ELBW infants with fortified donor human milk can shorten the time to achieve enteral nutrition and reduce the use rate and time of PICC, the incidence of late-onset sepsis, and the times of red blood cell transfusion.
