ObjectiveTo explore the mechanism of Xianfang Huomingyin （XFHMY） in the treatment of type Ⅲ prostatitis （CP/CPPS） through network pharmacology， molecular docking， and animal experiments. MethodsThe traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the Swiss Target Prediction database were used to screen and sort out the active ingredients and corresponding targets of XFHMY. The potential therapeutic targets of CP/CPPS were collected from online databases， such as the Online Mendelian Inheritance in Man （OMIM）， GeneCards， and DisGeNET. The potential core targets of XFHMY for treating CP/CPPS were further screened by constructing a protein-protein interaction （PPI） network and performing topological analysis. Meanwhile， the DAVID database was chosen to perform enrichment analysis on the intersection targets. On this basis， the AutoDock software was used for molecular docking， and the data was subsequently imported into the GraphPad Prism 8 software to generate a heat map. SD rats were divided into seven groups： A blank group， a sham operation group， a model group， low-， medium-， and high-dose XFHMY groups （3.645， 7.29， 14.58 g·kg^-1）， and a tamsulosin hydrochloride group （0.018 mg·kg^-1）. Hematoxylin-eosin （HE） staining was used to evaluate the pathological changes in prostate tissue. The inflammatory factor indicators of rats in each group were detected via enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （Real-time PCR） and Western blot were used to evaluate the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， and nuclear transcription factor-κB （NF-κB） p65 in prostate tissue. ResultsThe HE staining showed no significant signs of inflammatory cell infiltration in the prostate of the sham operation group compared to the blank group， while the model group had significantly inflammatory cell infiltration. The ELISA results showed that compared to the blank group， TNF-α， IL-1β， and COX-2 in the sham operation group had no significant differences. However， they were significantly higher in the model group （P<0.01）， indicating successful CP/CPPS modeling in rats. Compared with the model group， the low-，medium-and high-dose XFHMY group and the tamsulosin hydrochloride group showed significant decreases in TNF-α， IL-1β， and COX-2 （P<0.05，P<0.01）. The Real-time PCR analysis revealed that compared to the model group， the low-dose XFHMY group had reduced Akt and NF-κB p65 mRNA expression（P<0.05，P<0.01）. In the medium-and high-dose XFHMY group and tamsulosin hydrochloride group， PI3K， Akt， and NF-κB p65 mRNA levels decreased significantly（P<0.05，P<0.01）. Western blot analysis showed that compared to the model group， the low-dose XFHMY group had lower p-NF-κB p65/NF-κB p65 （P<0.05）. The medium- and high-dose XFHMY group and the tamsulosin hydrochloride group showed significant decreases in p-PI3K/PI3K， p-Akt-ser473/Akt， p-Akt-thr308/Akt， and p-NF-κB p65/NF-κB p65 （P<0.01）. ConclusionXFHMY may exert therapeutic efficacy on CP/CPPS by inhibiting the PI3K/Akt/NF-κB signaling pathway and reducing inflammatory responses. Additionally， NF-κB activation may be related to the activation of ser473 and thr308 sites.

Objective To establish a DNA quantitation method based on dithiothreitol(DTT)-crystal vio-let.Methods DTT was used to decolorize crystal violet,mixed with different concentrations of λ-DNA and salmon sperm DNA standard samples or concentration standard samples,and the absorbance was read at 595 nm wavelength by microplate reader,and compared with the results of ultraviolet absorbance method.DTT-crystal violet method and ultraviolet absorbance method were used to compare the concentration of plasmid samples and the concentration of genomic DNA samples of cervical exfoliated cells.The protein tolerance of the two methods was assessed by simulating protein contaminants with bovine serum albumin(BSA).Results In the quantification of λ-DNA and salmon sperm DNA,the DTT-crystal violet method had a robust linear correlation between the absorbance at 595 nm and DNA concentration(r2＞0.95),and the measured concentrations of the standard samples were not significantly different from the theoretical concentrations of the prepared standard samples(P＞0.05).There was no significant difference in the concentration of plasmid samples measured by DTT-crystal violet method and ultraviolet absorption method(P＞0.05).The concen-tration of DNA samples from cervical exfoliated cells measured by ultraviolet absorption method was positive-ly correlated with that by DTT-crystal violet method(r=0.94,P＜0.01).The concentration of the standard sample containing BSA 1 μg/μL measured by ultraviolet absorption method was higher than that of the con-trol sample,and the difference was statistically significant(P＜0.01),whereas the DTT-crystal violet method was not significantly affected(P＞0.05).Conclusion DTT-crystal violet method has obvious advantages over the existing DNA quantitation method,and is suitable for DNA quantitative analysis in scientific research and clinic.

[Purpose]To analyze the incidence and mortality of pancreatic cancer in 2020 and the change trend from 2010 to 2020 in cancer registration areas of Gansu Province.[Methods]The data of pancreatic cancer from 2010 to 2020 were collected from cancer registries in Gansu Province.The crude incidence/mortality rate,age-standardized incidence/mortality rate by Chinese standard population(ASIRC/ASMRC)and world standard population(ASIRW/ASMRW),0～74 years old cumulative rate and proportion of pancreatic cancer were calculated.Joinpoint 4.7.0 software was used to calculate the average annual percentage change(AAPC)of ASIRC/ASMRC of pancreatic cancer in cancer registration areas of Gansu Province from 2010 to 2020.[Results]In 2020,a total of 838 new cases of pancreatic cancer were reported in the cancer registration areas of Gansu Province,with a crude incidence rate of 6.52/105,ASIRC and ASIRW of 4.03/105 and 4.49/105 respectively,accounting for 2.50％of all malignant tumor incidence.In 2020,702 cases of pan-creatic cancer deaths were reported in the cancer registration areas of Gansu Province,with a crude mortality rate of 5.46/105,ASMRC and ASMRW of 3.25/105 and 3.73/105,respectively,ac-counting for 3.98％of all malignant tumor deaths.From 2010 to 2020,a total of 2 413 cases of pancreatic cancer were reported in cancer registration areas in Gansu Province,accounting for 1.90％of all malignant tumors in the province.The crude incidence rate of pancreatic cancer was 5.28/105,the ASIRC was 4.18/105,the ASIRW was 4.63/105,and the cumulative rate of 0～74 years old was 0.49％.From 2010 to 2020,a total of 1 871 pancreatic cancer deaths were reported in cancer registration areas of Gansu Province,accounting for 2.38％of all malignant tumor deaths in the province.The crude mortality rate was 3.92/105,the ASMRC was 3.09/105,the ASMRW was 3.50/105,and the cumulative rate of 0～74 years old was 0.36％.In terms of sex and region,the incidence and mortality of pancreatic cancer from 2010 to 2020 in men were higher than those in women,and higher in rural areas than those in urban areas.From 2010 to 2020,the incidence and mortality were at a low level under the age of 44 years old,and increased significantly after 45 years old,reaching a peak in the age group of 80～84 years old.ASIRC showed no significant change from 2010 to 2020 with an AAPC of 0.41 1％(P＞0.05).From 2010 to 2020,the ASMRC showed an significantly increasing trend with an AAPC of 6.515％(P=0.014).[Conclusion]From 2010 to 2020,the ASRIC of pancreatic cancer in Gansu Province showed no significant change,while the ASMRC showed a significantly in-creasing trend.The incidence and mortality rates were higher in men than those in women and higher in rural areas than those in urban areas.Middle-aged and elderly men in rural areas are the key groups of prevention and treatment of pancreatic cancer,so targeted prevention and control measures should be carried out.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective To understand the current situation as well as the implementation of infection prevention and control measures against bacterial contamination of external and vaginal ultrasound probes in medical institutions(MIs),and explore the risk of ultrasound probe-related infection under current prevention and control measures.Methods Through on-site sampling,external ultrasound probes from 179 MIs and vaginal ultrasound probes from 83 MIs in 15 prefecture-level cities in Henan Province underwent quantitative bacterial detection,and the implemen-tation of relevant infection prevention and control measures was assessed using questionnaire survey.Results A to-tal of 513 ultrasound probe specimens were detected.Bacterial detection rate and exceedance rate of the disinfected vaginal ultrasound probes were 18.02％(20/111)and 2.70％(3/111),respectively,which were both lower than external ultrasound probes(40.05％[161/402]and 5.22％[21/402],respectively).Bacterial detection rate of dis-infected specimens was lower than that of the towel-wiping group([33.86％,149/440]vs[50.00％,27/54],x2=5.46,P=0.019).Bacterial detection rate of the quaternary ammonium salt disinfectant group was lower than that of the alcohol disinfectant group([17.31％,18/104]vs[40.63％,128/315],x2=18.74,P＜0.001).The quali-fied rates of specimens using different disinfection methods and with different probe types showed no statistically significant differences(all P＞0.05).The implementation rates of"single disinfection for every use"for external ul-trasound probes and vaginal ultrasound probes were 60.34％(108/179)and 70.54％(79/112),respectively.The disinfectants used were mainly quaternary ammonium salts(57.27％)and alcohols(36.36％).The coupling agents used for external and vaginal ultrasound examinations were mainly large packaged products for multiple time use,accounting for 93.85％and 57.89％,respectively.33.33％(56/168)of external ultrasound coupling agents and 20.00％(11/55)of vaginal ultrasound coupling agents were used for more than 7 days.In vaginal ultrasound exa-minations,the usage rates of disinfectant coupling agents and sterile coupling agents were 28.42％(27/95)and 14.74％(14/95),respectively.In vaginal ultrasound examinations,50.00％(56/112)of MIs used condoms as probe co-vers,and 45.54％(51/112)used sound-transmission ultrasound isolation membranes.60.55％(66/109)of MIs didn't change gloves after cleaning and disinfecting the vaginal ultrasound probe and before examination.Conclusion Ultrasound probes have cross infection risks in key processes such as reprocessing(disinfection/sterilization),phy-sical barrier use,coupling agent selection,and glove replacement.It is urgent to develop and implement standar-dized ultrasound probe infection prevention and control technical specifications based on evidence-based research.

Objective To explore the effect of adeno-associated virus sense transfection up-regulating the expression level of the growth and differential factor 11 (GDF11) in vivo on aortic injury in type 2 diabetic mellitus rats (T2DM).Methods Nine-week-old male SD rats were randomly selected to establish a T2DM model by using high-sugar and high-fat chow plus small-dose streptozotocin (STZ) combined induction.Both normal rats and dia-betic model rats were randomly divided into five groups:blank control group (Control group) , negative virus con-trol group (NC group), GDF11 adeno-associated virus group (GDF11 group), diabetic group (DM group), and diabetic + GDF11 adeno-associated virus group (DM+GDF11 group) .After 8 weeks of feeding, the serum con-centrations of insulin (INS) , advanced glycosylation end products (AGES) , recombinant growth transforming fac-tor 11 (GDF11), total cholesterol (T-CHO), triglycerides (TG), low-density lipoproteins (LDL-C), high-densi-ty lipoproteins (HDL-C) , asymmetric dimethylarginine (ADMA) , and malondialdehyde (MDA) were assayed in the rats;periodic acid-schiff stain(PAS stain) was used to observe the sites of glycogen deposition, and hematoxy-lin-eosin staining (HE) was used to observe vascular damage.Scanning electron microscopy was used to observe the damage of vascular endothelial cells and vascular elastic fibers, and protein blotting and immunohistochemistry were used to detect the expression levels of vascular injury-related proteins.Protein blotting and immunohistochem-istry were used to detect the expression levels of vascular injury-related proteins.Results The biochemical inde-xes showed that the serum concentrations of AGES, T-CHO, TG, LDL-C and MDA were higher in the DM group than those in the Control group (P<0.05), the concentrations of INS, GDF11, HDL-C and ADMA were signifi-cantly lower than those in the Control group (P<0.05) , and the concentrations of AGES and HDL-C were not sig-nificantly lower in the DM+GDF11 group compared with the DM group (P<0.05) .HDL-C was not significantly different from the DM group, and several other data were improved (P<0.05) .Pathological staining suggested that PAS staining in the DM group suggested that glycogen particles deposited in the endothelium and subendotheli-um of the aorta, HE staining observed thickening of the aortic mesentery, endothelial cells and elastic fibers broke off in an irregular alignment, and electron microscopy observed endothelial damage in the vasculature and elastic fi-bers broke off in the DM group, and these changes attenuated in the DM+GDF11 group.Protein blotting and im-munohistochemistry indicated that the expression of endothelial cell-associated proteins decreased in the DM group (P<0.05) , and mesenchymal markers elevated in the DM group (P<0.05) , these proteins were regressed in the DM+GDF11 group, and the difference was statistically significant (P <0.05).Conclusion Increasing the expression level of GDF11 in vivo can improve aortic vascular injury caused by diabetes mellitus, which is inferred that it may be related to the inhibition of endothelial mesenchymal transition to protect the function of vascular endo-thelial cells and thus improve vascular injury.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.
