OBJECTIVES: To investigate the most common concomitant symptoms and the urgent demand of solution in the breast cancer patients undergoing postoperative endocrine treatment, as well as the acceptance and expectation of acupuncture in the patients so as to provide the scientific data for promoting the application of acupuncture in the breast cancer patients. METHODS: Breast cancer patients treated in Tianjin Medical University Cancer Institute and Hospital from January 2022 to March 2023 were randomly selected as the subjects. Using "questionnaire star" website, the questionnaire was conducted to investigate the relevant concomitant symptoms of the patients in postoperative endocrine treatment and the questions related to acupuncture treatment. RESULTS: In this study, 229 questionnaires were distributed and 211 valid ones were collected, with the response rate of 92.1%. Among these patients, the first three common symptoms were sleep disorders (157 cases, 74.4%), hot flashes (138 cases, 65.4%) and joint / muscle pain (118 cases, 55.9%)；the top three symptoms to be solved the most urgently were sleep disorders (131 cases, 62.1%), joint / muscle pain (62 cases, 29.4%) and hot flashes (45 cases, 21.3%). 79.1% of the patients (167 cases) were willing to receive acupuncture treatment because of the high expectations on its potential effect (93%). 20.9% of them (44 cases) refused acupuncture because they were worried not to be treated by the experienced physicians of TCM (52%) or afraid of needling feelings (48%). The average expectation value of acupuncture treatment was 4.02 points (5 points for the total score) among patients willing to receive acupuncture treatment. The main purposes of receiring acupuncture for the patients undergoing endocrine treatment were to strengthen the immune function (92%), reduce the adverse reactions (83%), and improve the physical condition (75%), et al. CONCLUSIONS: Sleep disorder is one of the most concerned symptoms in endocrine treatment for the patients after breast cancer surgery. The patients highly expect for acupuncture treatment even though some patients dislike the needling sensation. How to provide the acceptable and high-quality acupuncture services for cancer patients will be one of the major directions of acupuncture research in the future.

Bidirectional communication of the gut-brain axis: new findings in Parkinson's disease and inflammatory bowel disease.

Parkinson's disease (PD) and inflammatory bowel disease (IBD) are the two chronic inflammatory diseases that are increasingly affecting millions of people worldwide, posing a major challenge to public health. PD and IBD show similarities in epidemiology, genetics, immune response, and gut microbiota. Here, we review the pathophysiology of these two diseases, including genetic factors, immune system imbalance, changes in gut microbial composition, and the effects of microbial metabolites (especially short-chain fatty acids). We elaborate on the gut-brain axis, focusing on role of gut microbiota in the pathogenesis of PD and IBD. In addition, we discuss several therapeutic strategies, including drug therapy, fecal microbiota transplantation, and probiotic supplementation, and their potential benefits in regulating intestinal microecology and relieving disease symptoms. Our analysis will provide a new understanding and scientific basis for the development of more effective therapeutic strategies for these diseases.

TLR4 knockdown by miRNA-140-5p improves tendinopathy: an in vitro study.

Introduction: The purpose of this study was to determine whether TLR4 knockdown induced by miRNA-140-5p improves tendinopathy in an in vitro experiment. Material and methods: Extraction of tendon-derived stem cells (TDSCs) from SD rats was performed using TGF-ß1 to develop a tendinopathy cell model. In the first step, we knocked down TLR4 by si-TLR4 to investigate TLR4 in tendinopathy development, and the next we used miRNA-140-5p to investigate miRNA-140-5p in tendinopathy development. The inflammatory factors and Hyp concentration were evaluated by ELISA assay; the cell viability was measured by MTT assay; the cell apoptosis was evaluated by TUNEL and/or flow cytometry. The relative mRNA was measured by RT-qPCR assay; the relative proteins expression was evaluated by cellular immunofluorescence and/or WB assay. The correlation between miRNA-140-5p and TLR4 was analyzed by Luciferase reporter assay. Results: With miRNA-140-5p overexpression or TLR4 knockdown, the cell viability was significantly increased with cell apoptosis depressing compared with the Model group (p < 0.05, respectively). Meanwhile, the inflammatory factors TNF-α, IL-1ß and IL-6 and Hyp concentration were significantly improved (p < 0.05, respectively), whereas the TLR4, MyD88 and NF-κB(p65) protein expression levels were significantly depressed with TLR4 knockdown by si-TLR4 or miRNA-140-5p which target TLR4. Conclusions: The present results showed that TLR4 knockdown induced by miRNA-140-5p or si-TLR4 improved tendinopathy in an in vitro cell experiment.

Oxygen-regulated spontaneous solid electrolyte interphase enabling ultra-stable solid-state Na metal batteries.

Solid-state sodium metal batteries utilizing inorganic solid electrolytes (SEs) hold immense potentials such as intrinsical safety, high energy density, and environmental sustainability. However, the interfacial inhomogeneity/instability at the anode-SE interface usually triggers the penetration of sodium dendrites into the electrolyte, leading to short circuit and battery failure. Herein, confronting with the original nonuniform and high-resistance solid electrolyte interphase (SEI) at the Na-Na3Zr2Si2PO12 interface, an oxygen-regulated SEI innovative approach is proposed to enhance the cycling stability of anode-SEs interface, through a spontaneous reaction between the metallic sodium (containing trace amounts of oxygen) and the Na3Zr2Si2PO12 SE. The oxygen-regulated spontaneous SEI is thin, uniform, and kinetically stable to facilitate homogenous interfacial Na+ transportation. Benefitting from the optimized SEI, the assembled symmetric cell exhibits an ultra-stable sodium plating/stripping cycle for over 6600 h under a practical capacity of 3 mAh cm-2. Quasi-solid-state batteries with Na3V2(PO4)3 cathode deliver excellent cyclability over 500 cycles at a rate of 0.5 C (1 C = 117 mA cm-2) with a high capacity retention of 95.4%. This oxygen-regulated SEI strategy may offer a potential avenue for the future development of high-energy-density solid-state metal batteries.

Evaluation of the retention effect of nasointestinal canal indwelling in severe neurosurgical patients guided by miniature visualization system / 中国实用护理杂志

Objective:To investigate the feasibility, safety and reasonable operation of nasointestinal canal indwelling guided by miniature system in severe neurosurgery patients, and compare its advantages and disadvantages with traditional blind insertion.Methods:A prospective randomized controlled trial design was used to select 128 critically ill patients in need of enteral nutrition support at the Department of Neurosurgery, the First Affiliated Hospital of Nanjing Medical University from March 2022 to October 2023 by convenient sampling method. They were divided into blind insertion group and visualization group by random number table method, with 64 cases in each group. Nasointestinal canal indwelling was performed in the blind insertion group by traditional blind insertion method, and in the visualization group, nasointestinal canal indwelling was performed by indentations guided by the miniature visualization system. The success rate of initial catheterization, the time of catheterization, complications, changes of vital signs during catheterization and changes of nutritional indexes after catheterization were evaluated in 2 groups.Results:In the blind insertion group, there were 35 males and 29 females, aged (59.44 ± 13.84) years old. In the visualization group, there were 41 males and 23 females, aged (58.28 ± 12.08) years old. The success rate of the first catheter placement in the visual group was 96.8% (62/64), higher than that in the blind group 82.8% (53/64), and the difference was statistically significant ( χ2=6.94, P<0.05). The catheter placement time of the visualization group was (20.08 ± 2.69) min, which was shorter than that of the blind insertion group (38.19 ± 3.79) min, and the difference between the two groups was statistically significant ( t=29.99, P<0.05). There was no significant difference in the incidence of complications, changes of vital signs during catheterization and the changes of nutritional indexes after catheterization between two groups (all P>0.05). Conclusions:Compared with traditional blind nasointestinal canal indwelling, nasointestinal canal indwelling guided by the miniature visualization system can improve the success rate of the first catheterization and shorten the catheterization time. Although there is no difference in the complication rate, changes in vital signs during catheterization and changes in nutritional indexes after catheterization, it is believed that with the continuous development and upgrading of this technology, it will further reflect the advantages of this technology, which is worthy of further clinical trials and application.

Exploration of potential active ingredients and mechanism of action of Xihuang pill-medicated serum against glioma based on HPLC-Q-TOF-MS/MS, network pharmacology and experimental verification / 药学学报

Qualitative analysis of the ingredients absorbed into blood and their metabolites of Xihuang pill (XHP) were conducted using high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS/MS) technology. Network pharmacology was used to explore the potential anticancer mechanisms of the ingredients against glioma, and their specific mechanisms were validated through molecular docking and experimental verification. SD rats were intragastrically administered with XHP, and rat serum samples were collected. Ingredients absorbed into blood and their metabolites were identified based on the retention time of chromatographic peaks, accurate molecular mass, characteristic fragment ions, and comparisons with reference substances and literature data. PharmMapper and SwissTarget Prediction databases were used to obtain the targets of the XHP-medicated serum, while GeneCards, OMIM, PharmGKB, TTD, and DrugBank databases were used to obtain glioma disease targets. The "component-target" network relationship diagram was constructed using Cytoscape 3.9.1 software. The protein-protein interaction (PPI) network diagram was constructed using the STRING database, and the targets were analyzed using GO and KEGG analyses. Molecular docking was used to verify the binding ability of core targets with their corresponding compounds in XHP-medicated serum. The potential mechanism of the anti-glioma effect of 11-keto-β-boswellic acid (KBA), a representative component of XHP-medicated serum, was verified using CCK-8 and Western blot assays. A total of 40 compounds were identified in the XHP-medicated serum, including 28 prototype components and 12 metabolites. The network pharmacology results showed that elemonic acid, 3-acetyl-β-boswellic acid, KBA, α-boswellic acid, and other 5 compounds might be the active ingredients of XHP-medicated serum in the treatment of glioma. Glutathione reductase (GSR), glucose-6-phosphate dehydrogenase (G6PD), ATP-citrate lyase (ACLY), aldo-keto reductase family 1 member B1 (AKR1B1) and glutaredoxin (GLRX) were identified as key targets, involving pathways such as glutathione metabolism and the pentose phosphate pathway. Further cell experiments showed that KBA significantly inhibited the proliferation of T98G cells with an IC50 of 30.96 μmol·L-1, and KBA (30 μmol·L-1) significantly downregulated the protein expression levels of GSR in T98G cells. In summary, XHP-medicated serum may exert its anti-glioma effect by regulating GSR and G6PD-targeted pathways involved in glutathione metabolism. These results provide valuable evidence for further investigating the mechanism of XHP in treating glioma. The animal welfare and experimental procedures were approved by the Ethical Committee of Laboratory Animals at Nanjing University of Chinese Medicine (approval No. ACU221001).

Three-dimensional finite element analysis of medial patellofemoral ligament reconstruction with transosseous and wire anchor fixation / 中国组织工程研究

BACKGROUND:Reconstruction of the medial patellofemoral ligament is the primary and basic treatment for patellofemoral dislocation.Generally,autologous or allogeneic tendons are used to fix the patellofemoral podogram area and the femoral insertion,respectively.There are various fixation methods.Patellar lateral insertion fixation methods are relatively diverse,mainly traditional transosseous fixation and recent anchoring methods,including single tunnel,double-tunnel transosseous fixation,and two-wire anchor fixation.However,which fixation method is more effective in reducing patellofemoral joint stress and is more biomechanical has not been determined. OBJECTIVE:To observe the mechanical effects of patellofemoral joint and medial patellofemoral ligament reconstruction with transosseous and wire anchor fixation. METHODS:A three-dimensional finite element model of the knee joint was constructed.The medial patellofemoral ligament was reconstructed by a single tunnel through the bony canal or two wire anchors at the medial edge of the patella.The femoral side was fixed by extrusion nails to the medial epicondyle of the femur and the midpoint of the adductor tubercle.We observed the effects of the two fixation methods on patellofemoral joint and medial patellofemoral ligament loading during knee flexion at 0°,30°,60°,90°,and 120°. RESULTS AND CONCLUSION:(1)The stress on the patellofemoral joint was large when the knee was at flexion of 0-60°,peaked at 30°,and gradually decreased at 90° and 120°.The two fixation methods had little difference in the stress on the patellofemoral joint.(2)The stress on the medial patellofemoral ligament peaked at 30° and decreased significantly at 60°,and the load on the medial patellofemoral ligament was significantly greater at all angles with anchor fixation than with bony canal fixation.(3)The results showed that there was no significant difference in patellofemoral joint loading between the two fixation methods,but the stress on the medial patellofemoral ligament in anchoring was significantly greater than that in transosseous fixation.

Bioinformatics identification and validation of genes related to fatty acid metabolism in rheumatoid arthritis / 中国组织工程研究

BACKGROUND:Research has shown that fatty acid metabolism genes are closely related to the development of rheumatoid arthritis.Therefore,exploring the progression of rheumatoid arthritis based on fatty acid metabolism genes is of clinical significance. OBJECTIVE:To investigate whether fatty acid metabolism genes can serve as reliable biomarkers for predicting the progression of rheumatoid arthritis. METHODS:Gene data related to synovial tissue were downloaded from the Gene Expression Comprehensive Database(GEO).STRING was used to construct the protein-protein interaction network analysis.Cytoscape was utilized for biological annotation(gene ontology)and signaling pathway enrichment analysis(Kyoto Encyclopedia of Genes and Genomes).Fatty acid metabolism related genes were screened from the molecular feature database(MSigDB).Least absolute shrinkage and selection operator and support vector machine recursive feature elimination feature were used to screen for potential biomarkers.Immune cell infiltration levels in normal individuals and rheumatoid arthritis patients were assessed using the CIBERSORT algorithm.Finally,the expression levels of fatty acid metabolism related genes were verified using the receiver operating characteristic curve in GSE77298. RESULTS AND CONCLUSION:361 differentially expressed genes in rheumatoid arthritis were identified,of which 13 overlapped with the reported fatty acid metabolism related genes.Based on machine learning algorithms,five genes were selected,and the receiver operating characteristic curve showed that five genes(PCK1,PDK1,PTGS2,PLA2G2D,and DPEP2)could predict the development of rheumatoid arthritis.The CIBERSORT algorithm results showed that five genes were associated with activated mast cells,neutrophils,resting mast cells,and memory resting CD4+ T cells.The receiver operating characteristic curve showed that PLA2G2D and PCK1 have high diagnostic value.To conclude,the expression characteristics of fatty acid metabolism related genes can serve as potential biomarkers for predicting clinical outcomes,which can further improve the accuracy of prediction in RA patients.

(3) Logistic regression results showed that admission homocysteine levels ( OR 1.311,95% CI 1.008-1.705, P=0.044), admission NIHSS scores ( OR 1.588,95% CI 1.074-2.349, P=0.020), and overall brain average slow-wave index were influencing factors for poor prognosis in cerebral hemorrhage ( OR 8.596,95% CI 1.088-67.889, P=0.041). (4) ROC curve analysis revealed that the AUC for predicting adverse outcomes in cerebral hemorrhage was 0.768 (95% CI (0.665, 0.872)) for admission homocysteine levels, 0.743 (95% CI (0.634, 0.852)) for the overall brain average slow-wave index, and 0.896 (95% CI (0.827, 0.965)) for admission NIHSS. The cutoff values were 15.67, 3.62, and 8.5, respectively. Sensitivity was 77.8%, 71.1%, and 68.9%, and specificity was 59.4%, 68.7%, and 100%, respectively. The Youden indices were 0.372, 0.398, and 0.689. Conclusion:In the acute phase of cerebral hemorrhage, electroencephalographic physiological changes manifest shows an increase in the δ, θ, and slow-wave index throughout the entire brain. Higher admission homocysteine levels suggest a worse prognosis in patients with cerebral hemorrhage. Admission homocysteine levels and overall brain average slow-wave index have certain predictive value for adverse outcomes in acute cerebral hemorrhage.

ObjectiveTo investigate the effects of epidural analgesia plus dexmedetomidine infusion on postpartum depression in parturients with natural childbirth. MethodsWe selected 70 parturients aged between 22 and 36， with singleton， term， cephalic presentation， natural delivery and ASA class I or Ⅱ. The cases undergoing epidural analgesia with ropivacaine and sufentanil were randomly divided into two groups by using a random number table （n=35 for each group）. The control group （Group C） used intravenous infusion of normal saline， while the experimental group （Group D） used equivalent volumes of intravenous infusion of dexmedetomidine. Participants were followed up at 1， 6， 12 weeks after childbirth to assess the severity of postpartum depression. Blood samples were collected at 12 h and 48 h after childbirth to measure the serum prolactin levels. The hemodynamic （HR and MAP） changes， VAS scores， and Ramsay scores were recorded at five time points： before analgesia （T1）， 10 min after analgesia （T2）， 30 min after analgesia （T3）， 12 h （T4） and 24 h （T5） after delivery. The number of analgesia pump presses and adverse events were also documented. ResultsCompared with Group C， Group D showed significantly lower EPDS scores at 1 week after childbirth， significantly higher prolactin concentrations at 12 h and 48 h after childbirth， significantly lower VAS scores at T2， T3 and T4， significantly higher Ramsay score at T3 and significantly reduced number of analgesia pump presses （P < 0.05）. ConclusionEpidural analgesia plus intravenous infusion of dexmedetomidine can alleviate early postpartum depression in women undergoing natural delivery， promote early prolactin secretion and provide a safe and effective adjunctive analgesic and sedative effect.

Serum Anti-Fumarate Hydratase Autoantibody as a Biomarker for Predicting Prognosis of Acute-on-Chronic Liver Failure

Background/Aims@#To investigate the autoantibody against fumarate hydratase (FH), which is a specific liver failure-associated antigen (LFAA) and determine whether it can be used as a biomarker to evaluate the prognosis of acute-on-chronic liver failure (ACLF). @*Methods@#An immunoproteomic approach was applied to screen specific LFAAs related to differential prognosis of ACLF (n=60). Enzyme-linked immunosorbent assay (ELISA) technology was employed for the validation of the frequency and titer of autoantibodies against FH in ACLF patients with different prognoses (n=82). Moreover, we clarified the expression of autoantibodies against FH in patients with chronic hepatitis B (n=60) and hepatitis B virus-related liver cirrhosis (n=60). The dynamic changes in the titers of autoantibodies against FH were analyzed by sample collection at multiple time points during the clinical course of eight ACLF patients with different prognoses. @*Results@#Ultimately, 15 LFAAs were screened and identified by the immunoproteomic approach.Based on ELISA-based verification, anti-FH/Fumarate hydratase protein autoantibody was chosen to verify its expression in ACLF patients. ACLF patients had a much higher anti-FH autoantibody frequency (76.8%) than patients with liver cirrhosis (10%, p=0.000), patients with chronic hepatitis B (6.7%, p=0.022), and normal humans (0%, p=0.000). More importantly, the frequency and titer of anti-FH protein autoantibodies in the serum of ACLF patients with a good prognosis were much higher than that of patients with a poor prognosis (83.9% vs 61.5%, p=0.019; 1.41±0.85 vs 0.94±0.56, p=0.017, respectively). The titer of anti-FH autoantibodies showed dynamic changes in the clinical course of ACLF. @*Conclusions@#The anti-FH autoantibody in serum may be a potential biomarker for predicting the prognosis of ACLF.

A comparative study of two single-stage oral mucosal substitution urethroplasty (Kulkarni and Asopa) in the surgical treatments of lichen sclerosus urethral strictures / 亚洲男科学杂志(英文版)

Long-segment lichen sclerosus (LS) urethral stricture is a challenge for urologists. Limited data are available for surgeons to make a surgical decision between Kulkarni and Asopa urethroplasty. In this retrospective study, we investigated the outcomes of these two procedures in patients with LS urethral stricture. Between January 2015 and December 2020, 77 patients with LS urethral stricture underwent Kulkarni and Asopa procedures for urethroplasty in the Department of Urology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine (Shanghai, China). Of the 77 patients, 42 (54.5%) underwent the Asopa procedure and 35 (45.5%) underwent the Kulkarni procedure. The overall complication rate was 34.2% in the Kulkarni group and 19.0% in the Asopa group, and no difference was observed ( P = 0.105). Among the complications, no statistical difference was observed in the incidence of urethral stricture recurrence ( P = 0.724) or glans dehiscence ( P = 0.246) except for postoperative meatus stenosis ( P = 0.020). However, the recurrence-free survival rate between the two procedures was significantly different ( P = 0.016). Cox survival analysis showed that antiplatelet/anticoagulant therapy use ( P = 0.020), diabetes ( P = 0.003), current/former smoking ( P = 0.019), coronary heart disease ( P < 0.001), and stricture length ( P = 0.028) may lead to a higher hazard ratio of complications. Even so, these two techniques can still provide acceptable results with their own advantages in the surgical treatment of LS urethral strictures. The surgical alternative should be considered comprehensively according to the patient characteristics and surgeon preferences. Moreover, our results showed that antiplatelet/anticoagulant therapy use, diabetes, coronary heart disease, current/former smoking, and stricture length may be contributing factors of complications. Therefore, patients with LS are advised to undergo early interventions for better therapeutic effects.

Expression of interleukin-37, vascular endothelial growth factor A, and transforming growth factor-β1 and their correlation with T cells in children with primary immune thrombocytopenia / 中国当代儿科杂志

OBJECTIVES@#To investigate the expression of interleukin-37 (IL-37), vascular endothelial growth factor A (VEGFA), and transforming growth factor-β1 (TGF-β1) in children with primary immune thrombocytopenia (ITP) and their correlation with T cells.@*METHODS@#A retrospective analysis was conducted on 45 children with ITP (ITP group) who were admitted to Handan Central Hospital from January 2020 to April 2022, and 30 healthy children who underwent physical examination during the same period were included as the healthy control group. The mRNA expression levels of IL-37, VEGFA, and TGF-β1 and the levels of regulatory T cells (Treg) and helper T cells 17 (Th17) were measured before and after treatment, and the correlation between the mRNA expression levels of IL-37, VEGFA, and TGF-β1 and the levels of Treg, Th17, and Treg/Th17 ratio were analyzed.@*RESULTS@#Compared with the healthy control group, the ITP group had a significantly higher mRNA expression level of IL-37 and a significantly higher level of Th17 before and after treatment, as well as significantly lower mRNA expression levels of VEGFA and TGF-β1 and significantly lower levels of Treg and Treg/Th17 ratio (P<0.05). After treatment, the ITP group had significant reductions in the mRNA expression level of IL-37 and the level of Th17 and significant increases in the mRNA expression levels of VEGFA and TGF-β1 and the levels of Treg and Treg/Th17 ratio (P<0.05). Correlation analysis showed that in the ITP group, the mRNA expression levels of IL-37 and TGF-β1 were negatively correlated with the levels of Treg and Treg/Th17 ratio (P<0.05) and were positively correlated with the level of Th17 (P<0.05) before and after treatment; the mRNA expression level of VEGFA was positively correlated with the levels of Treg and Treg/Th17 ratio (P<0.05) and was negatively correlated with the Th17 level (P<0.05) before and after treatment.@*CONCLUSIONS@#Abnormal expression levels of IL-37, VEGFA, and TGF-β1 may be observed in children with ITP, which is significantly associated with the imbalance of Treg/Th17 ratio. It is speculated that the cytokines such as IL-37, VEGFA, and TGF-β1 may be involved in the development and progression of ITP or may become important potential targets for the treatment of children with ITP.

Induction of Anxiety-Like Phenotypes by Knockdown of Cannabinoid Type-1 Receptors in the Amygdala of Marmosets / 神经科学通报·英文版

The amygdala is an important hub for regulating emotions and is involved in the pathophysiology of many mental diseases, such as depression and anxiety. Meanwhile, the endocannabinoid system plays a crucial role in regulating emotions and mainly functions through the cannabinoid type-1 receptor (CB1R), which is strongly expressed in the amygdala of non-human primates (NHPs). However, it remains largely unknown how the CB1Rs in the amygdala of NHPs regulate mental diseases. Here, we investigated the role of CB1R by knocking down the cannabinoid receptor 1 (CNR1) gene encoding CB1R in the amygdala of adult marmosets through regional delivery of AAV-SaCas9-gRNA. We found that CB1R knockdown in the amygdala induced anxiety-like behaviors, including disrupted night sleep, agitated psychomotor activity in new environments, and reduced social desire. Moreover, marmosets with CB1R-knockdown had up-regulated plasma cortisol levels. These results indicate that the knockdown of CB1Rs in the amygdala induces anxiety-like behaviors in marmosets, and this may be the mechanism underlying the regulation of anxiety by CB1Rs in the amygdala of NHPs.

Textual research on Bambusae Concretio Silicea / 中国中药杂志

By studying various ancient texts such as herbal classics and medical literature from different eras, it was found that there were discrepancies in the records about Bambusae Concretio Silicea(Tian Zhu Huang). In order to establish an accurate foundation, this research was based on ancient herbal literature and combined with plant morphology and investigative studies to examine its earliest mentions in ancient texts, nomenclature, medicinal properties, indications, and quality assessment standards. In the early records, Bambusae Concretio Silicea was referred to by several different names, such as "Zhu Huang" "Tian Zhu Huang" "Zhu Gao" "Zhu Tang", and "Zhu Huang". The earliest known formal usage of the name "Tian Zhu Huang" was found in the book Ri Hua-zi's Materia Medica(Ri Hua Zi Ben Cao). Throughout various ancient texts, the earliest recorded information about Bambusae Concretio Silicea also appeared in Ri Hua-zi's Materia Medica, not in Materia Medica of Sichuan(Shu Ben Cao) or other ancient texts. Ri Hua-zi's Materia Medica provided relevant descriptions of its origin, medicinal properties, and indications, albeit with some errors due to limited knowledge. However, this has been a valuable starting point for future research on Bambusae Concretio Silicea and holds pioneering significance in forming a mature system. As the research delved deeper, the medicinal properties of Bambusae Concretio Silicea have been consistent since Ri Hua-zi's Materia Medica, and the understanding has gradually improved through years of clinical verification. During the investigation process, the authors found limited records on the quality evaluation of Bambusae Concretio Silicea in ancient texts. Although the information is scarce, it serves as a foundational basis for establishing corresponding quality grading standards for Bambusae Concretio Silicea in the future.

Correlation of OCTN2 with the chemosensitivity of prostate cancer cells to oxaliplatin / 中国药房

OBJECTIVE To study the correlation of novel organic cation transporter 2 （OCTN2） with the chemosensitivity of prostate cancer cells to oxaliplatin. METHODS Tumor samples of patients receiving radical prostatectomy were collected， and OCTN2 protein was detected with immunohistochemistry； the primary cells of the specimen were cultivated to obtain prostate cancer cell line. Inductively coupled plasma mass spectrometry was used to detect the uptake of low concentration （0.1 μmol/L） of oxaliplatin by cancer cells. Real-time PCR and Western blot were used to detect the mRNA and protein expressions of OCTN2 in cancer cells； the prostate cancer cells with the highest and lowest expression of OCTN2 protein were selected， and IC50 of oxaliplatin to prostate cancer cells was analyzed by ATP-TCA method. The inhibitory rate of plasma peak concentration of oxaliplatin （50 μmol/L） to prostate cancer cells was detected by MTT assay. Spearman method was used to analyze the relationship of the uptake of oxaliplatin by prostate cancer cells with inhibitory rate of oxaliplatin to prostate cancer cells and 505916443@qq.com mRNA expressions of OCTN2. RESULTS OCTN2 was located on the membrane of cancer cells， and the uptake of zjdtztougao@163.com oxaliplatin by cancer cells was 0.283±0.264 （n＝12）mRNA and protein expression of OCTN2 varied significantly among different cancer cells. The sensitivity of cancer cells with high expression of OCTN2 to oxaliplatin （IC50 of 4.61 μmol/L） was higher than that of cancer cells with lower expression of OCTN2 （IC50 of 26.23 μmol/L）. The inhibitory rate of oxaliplatin to cancer cells was （25.4±10.8）% （n＝12）. There was a correlation between the uptake of oxaliplatin by prostate cancer cells and the inhibition rate of oxaliplatin to prostate cancer cells and mRNA expression of OCTN2 （P＜0.05）. CONCLUSIONS High-expressed OCTN2 may promote the uptake of oxaliplatin by prostate cancer cells， and its expression can serve as a reference for predicting the sensitivity of prostate cancer cells to oxaliplatin chemotherapy.
