Object To study the efficacy and potential mechanism of Tongbianling capsule in constipation. Methods The effects of Tongbianling capsule on intestinal motility in normal mice and carbon powder propulsion rate in small intestine of constipation model mice after were observed administration. The potential targets and key pathways of Tongbianling capsule in treating constipation were identified through network pharmacology. To verify the mechanism, the expression of p-PI3K/PI3K, p-AKT/AKT and CASP3 proteins in mouse colon tissue was detected by the western blot. Results The time for mice to excrete the first black stool was shortened and the number of fecal particles was increased in Tongbianling capsule administration group, and the carbon powder propulsion rate of mice in each Tongbianling capsule administration group was increased. The results of network pharmacology showed that treatment of constipation by Tongbianling capsule may be related to signaling pathways such as PI3K-Akt signaling pathway and 5-HT. The protein expression of p-PI3K/PI3K, p-AKT/AKT, and CASP3 in mouse colon tissue could be significantly downregulated in administration group. Conclusion Tongbianling capsule could effectively promote intestinal peristalsis in mice, increase the frequency of defecation, and effectively treat constipation. The mechanism of its action may be related to the direct or indirect regulation of intestinal motility by the PI3K-Akt signaling pathway.

ObjectiveTo determine the optimal combination of the effective monomer components "quercetin-kaempferol-abietic acid-boswellic acid" in Fujin Shengjisan for promoting diabetic ulcer （DU） wound healing through uniform design， thereby achieving the modern application of the ancient formula. MethodsFollowing the principle of "uniform design-pharmacodynamic experiment-mathematical modeling and model verification"， the U₁₄（14⁵） uniform design table was adopted.The four monomer components of Chinese medicine were considered as the independent variables， and the proliferation rate of human umbilical vein endothelial cells （HUVECs） induced by glucose was used as the pharmacodynamic indicator. A mathematical model was constructed using DPS software to correlate the effective monomer components with the pharmacodynamic indicator. The results of uniform design were verified through CCK-8 assay， cell scratch healing， tube formation， Western blot， and Real-time PCR. ResultsAmong the 14 compatibility groups， compared with the high-glucose model group， compound compatibility group 6 showed the strongest proliferation effect and statistical significance （P<0.05）. Four quadratic polynomial regression equations （Y₁-Y₄） were obtained through DPS modeling. Considering the model's fit， stability， and practical application， equations Y₁-Y₃ were selected for the follow-up verification. To ensure experiment reproducibility， group 6 was used for validation. Group 6 and equations Y₁-Y₃ were renamed as compound prescription ① to compound prescription④， respectively， to represent the modern application of the ancient FJSJ Powder through compatibility of monomer components. Verification experiments showed that in the CCK-8， scratch healing， and tube formation assays， the cell viability， wound healing rate， and tube formation number of HUVECs stimulated with 50 mmol·L^-1 glucose were significantly reduced compared with the blank group. Moreover， the expression levels of angiogenesis-related cytokines， vascular endothelial growth factor （VEGF） and fibroblast growth factor 2 （FGF2）， and CD31 secretion were significantly down-regulated. However， after intervention with compound prescriptions ① to ④， compound prescriptions ① and ③ significantly improved the biological functions of HUVECs induced by 50 mmol·L^-1 glucose. Further analysis of the regression coefficients of compound prescriptions ① and ③， and the relative dose ratios of each monomer component， indicated that abietic acid， quercetin， and boswellic acid promoted angiogenesis of HUVECs in the high glucose environment， with a major effect （positive partial correlation coefficients， all > 0.9）. Abietic acid and boswellic acid， as well as kaempferol and boswellic acid， promoted angiogenesis in HUVECs through interaction （positive partial correlation coefficients）. ConclusionCompound prescriptions ① and ③ are the optimal combinations. They can reverse the inhibitory effects of high glucose， stimulate the proliferation， migration， and tube formation abilities of HUVECs in a high glucose environment， and promote the expression of vascular endothelial growth factorA（VEGFA）， FGF2， and CD31， thereby promoting angiogenesis and facilitating DU wound healing. This finding not only confirms the good reproducibility and feasibility of compound prescriptions ① and ③ but also provides new insights and methods for the rational construction of mathematical models to further study the compatibility theory of Chinese medicine.

Objective To investigate the setup error in patients with spinal bone metastasis who underwent radiotherapy under the guidance of kilovoltage cone-beam CT (KV-CBCT). Methods A total of 118 patients with spinal metastasis who underwent radiotherapy, including 17 cases of cervical spine, 62 cases of thoracic spine, and 39 cases of lumbar spine, were collected. KV-CBCT scans were performed using the linear accelerators from Elekta and Varian’s EDGE system. CBCT images were registered with reference CT images in the bone window mode. A total of 973 data were collected, and 3D linear errors were recorded. Results The patients with spinal bone metastasis were grouped by site, height, weight, and BMI. The P value of the patients grouped only by site was P<0.05, which was statistically significant. Conclusion When grouped by site in the 3D direction, the positioning effect of cervical spine is better than that of thoracic and lumbar spine. The positioning effect of the thoracic spine is better in the head and foot direction but worse in the left and right direction compared with that of the lumbar spine. Instead of extending or narrowing the margin according to the BMI of patients with spinal metastasis, the margin must be changed according to the site of spinal bone metastasis.

Objective: To evaluate the incremental vaccine effectiveness (VE) of two dose of the mumps containing vaccine (MuCV) in chidren, so as to provide a basis for optimizing mumps immunization strategies. Methods: A 1∶2 frequency matched case-control study was conducted by using reported mumps cases in childcare centers or schools from Lu an, Hefei, Ma anshan and Huainan cities of Anhui Province from September 1, 2023 to June 30, 2024, as a case group(383 cases). And healthy children in the same classroom were selected as a control group(766 cases). The MuCV immunization histories of participants were collected to estimate the incremental VE of the second dose of MuCV against mumps. Group comparisons were performed using the Chi square test or t-test. For matched case-control pairs, the Cox regression model was employed to calculate the odds ratio (OR) with 95% confidence interval (CI) for two dose MuCV vaccination and to estimate the incremental vaccine effectiveness (VE). Results: There were no statistically significant differences between the case and control groups regarding gender, age, dosage of MuCV vaccination and the time interval since the last dose vaccination( χ 2/t=0.05, 0.20, 0.94, -0.02, P >0.05). The proportions of the case and control groups vaccinated with two doses of MuCV were 26.63% and 29.37%, respectively, and the overall incremental VE of the second dose of MuCV was 40.73% (95% CI=3.03%-63.77%, P <0.05). Subgroup analyses revealed that the incremental VE for children with a period of ≥1 year between the two doses of MuCV was 54.13% (95% CI=1.90%-78.56%, P <0.05), while for children with a period of <1 year, it was 30.63% (95% CI=-28.59%-62.58%, P >0.05). The incremental VE of the second dose of MuCV was 30.36% (95% CI=-25.95%-61.50%, P >0.05) in kindergarten children and 66.73% (95% CI=14.92%-86.99%, P <0.05) in elementary and secondary school students. The incremental VE was 28.78% (95% CI=-27.46%-60.21%, P >0.05) within five years of the last dose of MuCV vaccination and 66.07% (95% CI=-41.56%-91.87%, P >0.05) for vaccinations administered beyond five years. Conclusions The second dose of MuCV may offer additional protection for children; however, extending the interval between two dose of MuCV (<1 year) has shown limited incremental protective effects. Therefore, it is crucial to consider optimizing current immunization strategies for mumps.

Aim To investigate the regulatory role and mechanism of resveratrol in inhibiting autophagy and promoting apoptosis in choroidal melanoma cells. Methods Choroidal melanoma cells (MUM2B) were divided into control and experimental groups, and treated with different concentrations of resveratrol (0, 10, 20,40,60,80 μmol ·L

Objective To investigate the impact of positive antinuclear antibody(ANA)and subsequent interven-tion therapy on the assisted reproductive technology outcomes among the patients experiencing recurrent implanta-tion failure(RIF).Methods A retrospective study was conducted on 344 RIF patients.Based on ANA test re-sults,the patients were divided into ANA-positive group(294 cases)and negative control group(50 cases).The ANA-positive group was further divided into a low titer group(214 cases)and a high titer group(80 cases).Com-parative statistical analyses such as the Wilcoxon rank-sum test,Mann-Whitney U test,Kruskal-Wallis test and chi-square test,etc.were employed to evaluate differences in general clinical data,embryo-related parameters,and pregnancy outcomes between the positive and negative groups.The impact of ANA on the assisted reproductive out-comes of patients with recurrent implantation failure was analyzed,and the outcomes of ANA-positive patients after intervention therapy were also analyzed.Results Notably,the clinical pregnancy rates of patients in the ANA-pos-itive low titer group and high titer group were significantly lower than those in the negative control group(P＜0.001).Similarly,the rates of fertilization and cleavage of oocytes in ANA-positive patients were also significantly lower than those in the negative control group(P＜0.05).For patients who did not achieve pregnancy after embryo transfer due to ANA positivity,immunomodulatory therapy significantly improved both the clinical pregnancy rate and cumulative clinical pregnancy rate(P＜0.05).Conclusion Compared with the negative control group,the clinical pregnancy rates decrease in both ANA-positive low titer subgroup and high titer subgroup.However,clini-cal intervention therapy enhances the single-cycle clinical pregnancy and cumulative pregnancy rates among ANA-positive patients,indicating that ANA positivity is an important factor in RIF.Immunomodulatory therapy is an ef-fective measure to improve recurrent implantation failure among ANA-positive patients.

Objective To explore the effect and possible pharmacological mechanism of Bufei Tongbi Decoction in the treatment of systemic lupus erythematosus interstitial lung disease (SLE-ILD).Methods The effective components and related targets of Bufei Tongbi Decoction were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Uniprot database. Key genes for SLE-ILD were screened based on DrugBank,DisGeNET,GeneCards,PharmGKB,OMIM,and GEO databases. Using Cytoscape software,a drug active ingredient-target-disease relationship network diagram was constructed to obtain the effective active ingredients and possible mechanisms of action of Bufei Tongbi Decoction in the treatment of SLE-ILD. Gene ontology (GO) function enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were used to reveal related target genes and pathway functions. Taking C57BL/6 mice as normal group,MRL/lpr mice were injected with bleomycin 5mg/kg in the nasal cavity. According to the random number table method,the mice were divided into model group,Bufei Tongbi Decoction low-dose group (10.4 g/(kg·d)),Bufei Tongbi Decoction medium-dose group (20.8 g/(kg·d)),Bufei Tongbi Decoction high-dose group (41.6 g/(kg·d)) and prednisone group (3 mg/(kg·d)). The intervention lasted for 28 days. Hematein eosin and Masson staining were used to observe the pathological changes of mouse lung tissue,the expressions of transforming growth factor-β1 (TGF-β1) and collagen type Ⅲ (Col-Ⅲ) in lung tissue were detected by immunohistochemistry,and the expressions of interleukin-1β(IL-1β),interleukin-10 (IL-10) and interleukin-17 (IL-17) in serum were detected by ELISA. The mRNA expressions of matrix metallopeptidase 1(MMP-1),hypoxia inducible factor-1α(HIF-1α),retinoid-related orphan receptor γt (RORγt ) and forkhead box P3 (FOXP3) in lung tissue were analyzed by RT-PCR,the protein expressions of HIF-1α and MMP-1 in lung tissue were detected by Western blotting,and the expressions of T helper 17 cells (Th17) and regulatory T cells (Treg cells) in blood were detected by cytometry.Results A total of 163 effective ingredients,259 targets,1729 SLE-ILD disease targets,958 SLE-ILD differential genes and 40 drug-disease interaction targets were obtained by screening. GO functional enrichment and KEGG pathway enrichment showed that IL-17 signaling pathway activated by IL-1β and MMP-1,and Th17 cell differentiation activated by IL-1β and HIF-1α were the main pathways. Animal experiments showed that Bufei Tongbi Decoction could effectively improve the degree of lung interstitial lesion and reduce the expressions of TGF-β1 and Col-Ⅲ in SLE-ILD mice (P<0.01). The expressions of IL-1β,HIF-1α and IL-17 were decreased (P<0.01). Medium and high doses of Bufei Tongbi Decoction decreased the expressions of MMP-1 and RORγt mRNA (P<0.01),and increased the expressions of IL-10 and FOXP3 mRNA (P<0.01). Bufei Tongbi Decoction could reduce the proportion of Th17 cells,increase the proportion of Treg cells,downregulate the balance of Th17/Treg (P<0.05),and improve the immune disorder. Conclusion Bufei Tongbi Decoction has the characteristics of multi-target and multi-pathway in treating SLE-ILD,and its mechanism may be related to the regulation of Th17/Treg cell balance.

Interventions for endometriosis(EMs)include surgical excision of lesions and hormonal therapy,which usually have limited efficacy and adverse drug reactions.Traditional Chinese medicine(TCM)has the multi-component and multi-target characteristics,which can help patients achieve good clinical benefits by intervening in different parts of the disease.In this paper,we briefly discuss the modern pharmacology of Sanlang and Curcuma longa,and deeply summarize the possible mechanisms of action of TCM monomer and classical compound extracts and their active ingredients through signal pathways in inflammation,immune system,angiogenesis,hormone regulation,etc.,so as to provide theoretical bases for the clinical use of TCM monomers,drug-to-drug groups and compounds in the treatment of EMs.

Objective We aimed to establish and evaluate a rat model of post-infectious irritable bowel syndrome(PI-IBS)with the pattern of liver depression and spleen deficiency coupled with dampness.Methods First,200 rats were randomly divided into the normal group,the infection group,the infection+stress group,the infection+stress+external dampness group,and the acetic acid+stress group(n=40 rats per group)for eight weeks.The rats were treated with Trichinella spiralis infection,chronic restraint stress,an artificial high-humidity climate,and/or acetic acid enema.Weight growth rate,24-hour food intake and water intake,and the fecal moisture percentage were recorded.The open field test and the sucrose consumption test were used to determine the behavioral characteristics of rats in each group.The abdominal withdrawal reflex(AWR)test was used to determine visceral sensitivity.The contents of 5-hydroxytryptamine(5-HT)and aquaporin 4(AQP4)in colon tissue were detected by ELISA.Results Compared with the normal group,the weight growth rate of rats in the infection+stress+external dampness group and the acetic acid+stress group was lower from Week 1 to Week 8 of modeling.The 24-hour food intake of rats in the infection+stress+external dampness group and the infection+stress group was lower than that in the normal group from Week 2 to Week 8 of modeling.At the end of week 2 of modeling,the 24-hour water intake of rats in the infection+stress+external dampness group,the acetic acid+stress group,and the infection+stress group was lower than that in the normal group.The fecal moisture percentage of rats in the infection+stress+external dampness group was higher than that in the normal group at the end of Week 1,6,and 8(P＜0.05).At the end of Week 4 of modeling,the total distance in the open field test in the infection+stress+external dampness group and the acetic acid+stress group was shorter than that in the normal group.The sugar preference rate in the infection+stress+external dampness group was lower than that in the normal group at the end of 1,4,and 8 weeks and lower than that in the acetic acid+stress group at the end of Week 4 and 8(P＜0.05).The AWR scores of rats in the infection+stress+external dampness group were higher than those in the normal group after week 1 at 60 and 80 mmHg(1 mmHg≈0.133 kPa),after Week 4 at 40,60,and 80 mmHg,and after Week 6 and 8 at 20,40,and 80 mmHg(P＜0.05).At the end of Week 2 and 4,a large number of inflammatory cells were infiltrated in the colonic mucosa of the intervention groups,and the inflammation score was higher than that of the normal group(P＜0.05).At the end of weeks 6 and 8,the inflammatory cell infiltration in the intestinal mucosa of the intervention groups was not obvious,and the colonic mucosa returned to normal.At the end of weeks 6 and 8,the 5-HT content was higher in the infection+stress group,the infection+stress+external dampness group,and the acetic acid+stress group than in the normal group(P＜0.05).After Week 4,the AQP4 content was lower in the infection+stress+external dampness group and the acetic acid+stress group than that in the normal group(P＜0.05).After week 6,compared to the normal group,the AQP4 content was lower in all groups except for the acetic acid+stress group,and the AQP4 content in the infection+stress+external dampness group was lower than that in the acetic acid+stress group.After week 8,only in the infection+stress+external dampness group the AQP4 content was lower than in the normal group(P＜0.05).Conclusion The combination of Trichinella spiralis infection,chronic restraint stress,and an artificial high-humidity climate can be used to prepare a relatively stable and reliable rat model of PI-IBS with the pattern of liver depression and spleen deficiency with dampness.

ObjectiveTo reveal the influence of Jianchangbang characteristic processing method on the change process of volatile components and the processing mechanism of reducing toxicity and increasing efficiency of Magnoliae Officinalis Cortex（MOC） by studying the changes in the composition and content of volatile components during the processing of ginger processed Xingpo pieces. MethodSamples of raw products， ginger juice moisturized products and stir-fried and heap moisturized products of MOC were taken according to the set time points， and headspace gas chromatography-mass spectrometry（HS-GC-MS） was used to determine the contents of volatile components in the samples， and the relative content of each component was obtained by peak area normalization. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were performed on the sample data using SIMCA 14.1 software， and the differential components during the processing were screened with variable importance in the projection（VIP） value>1 as the indicator. ResultA total of 68 volatile components were identified in the samples， among which some of the chemical components with similar structures showed similar trends of changes， and there was also the phenomenon of interconversion between compounds. Compared with the raw products， the contents of 42 components in ginger juice moisturized products increased， while the contents of 25 components decreased， 19 components were unique， and 4 components were unique to the raw products. Compared with ginger juice moisturized products， MOC in the early stage of piling had three unique components， and the contents of 11 components such as cyclosativene and （+）-α-pinene increased， and the contents of 5 components such as tricyclic terpene and α-curcumene decreased， and ginger juice moisturized products had four unique components. Compared with the early stage of piling， in the later stage， the contents of 8 components such as （+）-α-pinene and camphene significantly increased， while the contents of 6 components such as linalool and α-selinene significantly decreased. During the processing of MOC， there were significant changes in the chemical composition of the samples before and after 20 days. The differences between ginger juice moistening and the early stage of piling， the early stage and the later stage of piling could be clearly distinguished. ConclusionDuring the preparation process of ginger processed Xingpo pieces， the addition of ginger juice can reduce the contents of stimulating components， and the contents of active components continue to increase in several stages， such as the addition of ginger juice， frying and heap moisturizing， the quality of the decoction pieces may change significantly at about 20 d of processing. This study can provide a research basis for exploring the processing mechanism of ginger processed Xingpo pieces.
