Objective:The aim of this study is to evaluate the clinical efficacy of Oxalicao Formula combined with transacu-puncture in the treatment of chronic nonbacterial prostatitis(CNP)characterized by dampness-heat stasis.Methods:A total of 70 patients diagnosed with CNP and characterized by dampness-heat stasis were randomly divided into control group and treatment group,with 35 cases in each group.The patients in control group received Qianlie Beixi capsules.While the patients in treatment group were administered with oxalis decoction in conjunction with acupuncture therapy which lasted for 8 weeks.Pre-and post-treatment evalua-tions for NIH-Chronic Prostatitis Symptom Index(NIH-CPSI),Traditional Chinese Medicine(TCM)symptom scores,urodynamic pa-rameters,immune cell subsets and inflammatory factors were performed.Results:Ultimately,65 patients completed the study with 33 in the treatment group and 32 in the control group.After 8 weeks of intervention,the patients in both of groups demonstrated signifi-cant improvements(P＜0.05).Specifically,remarkable reductions in the NIH-CPSI total score including pain score,urination score,quality of life impact score,TCM symptom score and inflammatory cytokine levels were observed.Additionally,there were upward trends in maximum and average urinary flow rates as well as the CD4+/CD8+ratio of immune cells(P＜0.05).Compared to the con-trol group,the treatment group exhibited superior outcomes in reducing the NIH-CPSI total score,pain score,urination score,quality of life impact score,TCM symptom score,and inflammatory cytokine levels,and increasing in CD4+/CD8+ratios,maximum and av-erage urine flow rates(P＜0.05).Conclusion:The combination of Oxalicao Formula and transacupuncture for treating CNP charac-terized by dampness-heat stasis demonstrates significant therapeutic benefits,which has considerable clinical application value.

Miao medicine is guided by the medical theories of the Miao ethnic group,and the drugs used by the Miao people are derived from natural plants and animals for the prevention and treatment of diseases and protection of health.In recent years,a large number of clinical studies have shown good clinical efficacy of traditional Miao medicine in the treatment of prostatic diseases,with the advantages of easy availability,low price,and minimal adverse reactions.However,currently no systematic literature review has been reported on the treatment of prostatic diseases with Miao medicine.This article focuses on the commonly used Miao drugs recorded in the Chinese Materia Medica-Miao Medicine,with a systematic review of relevant literature retrieved on the treatment of prostate disea-ses with Miao medicine in recent years and a summarization of the advances in the studies of its pharmacological effects,mechanisms of action and clinical application,aiming to provide some new perspectives and ideas for further academic research and clinical develop-ment of Miao medicine.

Objective:To explore the clinical value of autologous umbilical cord whole blood(UCB) priming of the cardiopulmonary bypass(CPB) circuit in neonatal cardiac surgery for congenital heart disease(CHD).Methods:This prospective non-randomized controlled trial included neonates undergoing CHD surgery at Guangdong Provincial People’s Hospital from August 2024 to January 2025. The experimental group used autologous UCB for CPB circuit priming, while the control group used adult allogeneic blood(AAB) priming when UCB was unavailable. Preoperative characteristics, intraoperative CPB and aortic cross-clamping(ACC) times, postoperative ICU stay duration, mechanical ventilation time, and hospitalization length were compared.Results:There were no significant differences in preoperative baseline characteristics between the two groups( P>0.05). At the end of surgery, red blood cell count(RBC), hemoglobin level(Hb), and creatine kinase(CK) showed no significant differences between the groups( P> 0.05). Additionally, perioperative left ventricular ejection fraction(LVEF) demonstrated no statistically significant variations( P>0.05). At surgery completion, the UCB group exhibited lower hematocrit(HCT) and higher blood lactic acid(Lac) levels but these differences resolved by 6 hours postoperatively( P>0.05). The UCB group had higher maximum vasoactive-inotropic scores(VISmax) within 48 hours and longer ICU stays, though total hospitalization and mechanical ventilation durations showed no significant differences( P>0.05). Conclusion:Autologous UCB priming reduces AAB requirements and has minimal impact on postoperative cardiac and pulmonary function recovery, or homeostasis., which is safe and feasible. This study provides evidence supporting the clinical application of UCB priming in CPB circuits.

Objective:To study the role of cadherin 1 (CDH1) gene DNA methylation in autoimmune thyroiditis (AIT) in population from different water-iodine regions.Methods:From May to June 2019, the information of AIT cases and healthy individuals in Shandong Province were collected in three types of water-iodine regions: iodine-fortification (IF) region, iodine-adequate (IA) region and iodine-excess (IE) region. A case-control study design was applied to match 176 AIT cases (case group) with age, gender, body mass index, and place of residence in a 1 ∶ 1 ratio to 176 healthy individuals (control group). Fasting urine and whole blood samples were collected to test the contents of urinary iodine, thyroid function indicators [serum free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid stimulating hormone (TSH)], and serum iodine. The DNA methylation levels of the target region of the CDH1 gene and its four CpG sites in whole blood were determined using methylation sequencing technology for target regions (MethylTarget TM). Results:The DNA methylation level of the target region of CDH1 gene in the case group was 0.832 ± 0.044, and that in the control group was 0.828 ± 0.049, there was no statistically significant difference between the two groups ( t = 0.76, P = 0.448). There was no statistically significant difference in DNA methylation levels of the four CpG sites in the target region of CDH1 gene between the case group and the control group ( P > 0.05). There was no statistically significant difference in the DNA methylation level of the CDH1 gene target region between the case group and the control group in IF, IA and IE regions ( P > 0.05). The detection results of DNA methylation levels at CpG sites in the target region of CDH1 gene in different water iodine regions showed that the DNA methylation level at site 83 in case group in IF region was higher than that in the control group ( t = 2.30, P = 0.023). However, there was no statistically significant difference in the DNA methylation levels of the four CpG sites between the case group and the control group in IA and IE regions ( P > 0.05). The DNA methylation level of CDH1 gene target region in AIT patients was not significantly correlated with urinary iodine, serum iodine, and serum FT 3, FT 4, and TSH contents ( P > 0.05), but was significantly negatively correlated with age ( r =-0.19, P = 0.014). Conclusions:The DNA methylation level at CpG site 83 of CDH1 gene in AIT patients in IF region is significantly higher than that in control population, indicating that DNA methylation at this locus may be involved in the occurrence and development of AIT after iodine fortification. The DNA methylation level of CDH1 gene is negatively correlated with age.

BACKGROUND:Dental follicle cells are widely used in periodontal tissue regeneration engineering because of their excellent characteristics.With the development of biological scaffold materials,their relationship with periodontal tissue regeneration technology is increasingly close.OBJECTIVE:To review the performance of ivory follicle cells under the influence of internal and external biological factors by different experiments,and analyze their effects on the biological characteristics of dental follicle cells with scaffold materials.METHODS:Using"dental follicle cell,scaffolds,material,periodontal tissue regeneration,tissue engineering,review"as English and Chinese key words,the articles published in PubMed,Sciencedirect,and CNKI from 2013 to 2023 were searched,and finally 95 articles were included for analysis and discussion.RESULTS AND CONCLUSION:(1)Dental follicle cells originate from dental follicle tissue,which has certain stem cell differentiation potential.Because of its excellent performance,it is actively used in periodontal tissue regeneration engineering research.(2)The proliferation and osteogenic differentiation of dental follicle cells are affected by many biological factors,and both endogenous and exogenous factors can promote the proliferation and osteogenic differentiation of dental follicle cells to a certain extent.(3)3D printing technology and nanotechnology enable researchers to manufacture more suitable scaffold materials.(4)Polymer materials show us their flexibility and plasticity in periodontal tissue regeneration.We can manufacture targeted scaffold materials according to different defect sites to achieve efficient tissue regeneration.The good biocompatibility of inorganic materials makes them widely used in periodontal tissue regeneration engineering.By adjusting the content of nanoscale inorganic materials or improving the performance of scaffolds,scaffolds with better biocompatibility can be prepared.(5)There are many new synthetic(composite)materials,which show us excellent characteristics.However,because the mechanism of biological factors in scaffold materials on dental follicle cells is complicated,and the research on dental follicle cells is mostly concentrated on in vitro culture,so how to make scaffold materials more suitable for the growth and development of dental follicle cells and apply them safely and effectively in clinical treatment is the future research direction.

OBJECTIVE To screen endogenous differential metabolites in mice that die from chlor-promazine(CPZ)poisoning and investigate the detoxification mechanism of triheptanoin(TriHep)against CPZ-induced lethality.METHODS Mice were randomly divided into the following groups(half male and half female):normal control,CPZ 2.5LD50,CPZ LD50 intoxication(CPZI),CPZ LD50 death(CPZD),TriHep-control,and TriHep-intervention(TriHep+CPZ LD50).The CPZ 2.5LD50,CPZI and CPZD groups were intragastrically given a corresponding dose of CPZ,respectively.The TriHep-control group and the TriHep-intervention group were intragastrically given saline and CPZ LD50 respectively before being intragastrically given TriHep(3 μL·g-1)10 min later.Plasma samples from the CPZ 2.5LD50 group and normal control group were analyzed using liquid chromatography-tandem mass spectrometry(LC-MS/MS)for metabolite identification and quantification.MetaboAnalyst 5.0 was employed to perform principal component analysis(PCA),orthogonal partial least squares-discriminant analysis(OPLS-DA),and metabolic pathway analysis to screen and identify differential metabolites.More comparisons were made of the levels of differential metabolites in plasma between the normal control,CPZI,CPZD,TriHep-intervention,and TriHep-control groups.RESULTS In the PCA score plot,metabolomic samples from the CPZ 2.5LD50 group and normal control group showed clear separation,indicating distinct clus-tering patterns.Primary screening under three conditions,including P＜0.05,variable importance in projec-tion(VIP)score≥ 1 and fold change(FC)≥1.5 or ≤0.67 for a comparison of CPZ 2.5LD50 group with normal control group 28 metabolites were identified.Following quantitative enrichment and structural identifica-tion,three significantly differential metabolites were confirmed:acetylcarnitine,propionylcarnitine,and succinic acid.Compared with the normal control group,both CPZI and CPZD groups showed signifi-cantly decreased plasma levels of acetylcarnitine and propionylcarnitine,while the succinic acid content was markedly increased in the CPZD group.In the TriHep control group,levels of acetylcarnitine and succinic acid were significantly elevated,with no significant change in propionylcarnitine levels.Com-pared with the CPZI group,the CPZD group showed a significant increase in plasma succinic acid levels,but no significant change was observed in the acetylcarnitine content.The TriHep-intervention group demonstrated metabolite profiles(all the three differential metabolites)similar to those in the CPZI group,with significantly reduced propionylcarnitine and succinic acid concentrations compared to the CPZD group.CONCLUSION In the early stage of CPZ intoxication,TriHep can alleviate CPZ poisoning via acetylcarnitine,which can stabilize the level of succinic acid in plasma via indirect succinic acid replenishment.

OBJECTIVE: To reveal the molecular basis of knee osteoarthritis (KOA) with Yang deficiency and blood stasis syndrome by analyzing the gene expression profiles in synovial fluid and blood of KOA patients with this syndrome. METHODS: A total of 80 KOA patients were recruited from October 2022 to June 2024, including 40 cases in the non-Yang deficiency and blood stasis group (27 males and 13 females), with an average age of (61.75±3.45) years old;and 40 cases in the Yang deficiency and blood stasis group (22 males and 18 females), with an average age of (62.00±2.76) years old. The levels of body mass index (BMI), high-density lipoprotein (HDL), low-density lipoprotein (LDL), fibrinogen, total cholesterol, and D-dimer were recorded and summarized. Blood and synovial fluid samples from patients were collected for gene expression profile microarray sequencing, and then PCR and immunohistochemistry were used for clinical verification on the patients' synovial fluid and cartilage samples. RESULTS: Logistic regression analysis showed that compared with KOA patients with non-Yang deficiency and blood stasis syndrome, those with Yang deficiency and blood stasis syndrome had increased BMI, LDL, fibrinogen, total cholesterol, and D-dimer, and decreased HDL, with a clear correlation between the two groups. There were 562 differential genes in the blood, among which 322 were up-regulated and 240 were down-regulated;755 differential genes were found in the synovial fluid, with 350 up-regulated and 405 down-regulated. KEGG signaling pathway analysis of synovial fluid revealed changes in lipid metabolism-related pathways, including cholesterol metabolism, fatty acid metabolism, and PPARG signaling pathway. Analysis of the involved differential genes identified 6 genes in synovial fluid that were closely related to lipid metabolism, namely LRP1, LPL, ACOT6, TM6SF2, DGKK, and PPARG. Subsequently, PCR and immunohistochemical verification were performed using synovial fluid and cartilage samples, and the results were consistent with those of microarray sequencing. CONCLUSION This study explores the clinical and genomic correlation between traditional Chinese medicine syndromes and knee osteoarthritis from the perspective of lipid metabolism, and proves that abnormal lipid metabolism is closely related to KOA with Yang deficiency and blood stasis syndrome from both clinical and basic aspects.
