Objective To investigate the effects and mechanisms of combined prescriptions of essential oils from five traditional Chinese medicinal herbs,namely peppermint,turmeric,ginger,Tibetan fennel,and cumin,on symptoms related to functional abdominal pain syndrome(FAPS).Methods Gas chromatography-mass spectrometry(GC-MS)was employed to analyze the chemical constituents of five essential oils,while network pharmacology was utilized to predict the key targets and signaling pathways associated with these essential oils in alleviating functional abdominal pain syndrome.A formula design methodology centered on these core targets and signaling pathways was developed for creating new prescriptions.Molecular docking technology was conducted to predict its the underlying mechanisms.Subsequently,animal experiments were performed to assess pharmacological activity,including hot plate tests and acetic acid-induced writhing assays to validate the analgesic effects of the newly formulated prescription,as well as xylene-induced ear swelling tests to evaluate its anti-inflammatory properties.The impact of the essential oil formulation on intestinal peristaltic function was examined through intestinal propulsion experiments.Additionally,enzyme-linked immunosorbent assay(ELISA)methods were employed to measure levels of serotonin(5-HT),prostaglandin E2(PGE2),and gamma-aminobutyric acid(GABA)in brain tissue.Western blot analysis was conducted to determine protein expression levels of TPH1 and SERT in the intestine,along with TPH2 and SERT in the brain.Results The main chemical components in five essential oils were identified and screened(peppermint:12,turmeric:8,ginger:14,cumin:2,fennel:6).Based on the network pharmacology analysis,four new essential oil prescriptions were successfully designed according to the complementary relationship between the five essential oils in improving functional abdominal pain syndrome at the target level,including 4 new prescription named Prescription A,B,C and D,these four prescriptions were all based on ginger and turmeric essential oils,with other essential oils serving as supplements or enhancements.The results of animal experiments showed that Prescription D could significantly reduce the writhe frequency of mice(P<0.05),all the four groups could significantly prolong the pain threshold of mice(P<0.05),and Prescription C had a significant effect on reducing the degree of ear swelling(P<0.05).The prescription of essential oil did not significantly affect the function of peristalsis and the speed of propulsion.The levels of 5-HT and PGE2 in the brain tissue were significantly inhibited(P<0.05),and the level of GABA was significantly increased(P<0.05).Prescription C could reduce the expression of TPH1 in the intestinal tissue(P<0.05),Prescription A,C and D could reduce the expression of TPH2,and all groups had a tendency to increase the expression of SERT in the brain tissue.Conclusion In summary,the therapeutic effects of the four novel prescriptions composed of the five essential oils demonstrated potential in improving symptoms related to FAPS,the mechanism might be through modulating abnormalities in the brain-gut axis system.

Objective To explore the effect of evening primrose oil(EPO)on aortic endothelial damage in rats with polycystic ovary syndrome(PCOS),using network pharmacology and in vivo experiments.Methods The potential targets of EPO for improving aortic endothelial injury in PCOS rats were predicted by network pharmacology,and the selected core targets and renin-angiotensin signaling(RAS)pathway were verified by experiments.Fifty-eight female SD rats were divided randomly into a blank group(n=10)and a modeling group(n=48).Rats in the blank group were fed a normal diet and rats in the modeling group received a high-fat diet for 8 weeks.The PCOS model was prepared at week 6 by administration of letrozole(1 mg/(kg·d))for 21 days.Blood was taken from the tail vein after modeling and serum was collected to detect hormone levels.The model rats were then divided randomly into four groups and treated with the corresponding drugs for 6 weeks.Blood,blood vessels,and ovaries were then collected.Tissue morphology was examined by hematoxylin and eosin staining and serum levels of luteinizing hormone(LH),testosterone(T),follicle-stimulating hormone(FSH),endothelin(ET-1),and tumor necrosis factor(TNF-α)were detected by enzyme-linked immunosorbent assay(ELISA).Serum levels of nitric oxide(NO)were determined by spectrophotometry.Protein expression levels of core targets and RAS pathway-related factors were assessed by western blotting and immunohistochemistry.Results Twenty-five intersection targets of EPO and PCOS were identified by network pharmacological analysis.Kyoto encyclopedia of genes and genomes analysis showed that EPO improved vascular injury in PCOS rats via multiple pathways,including RAS.Serum levels of ET-1,FSH,LH,and T measured by ELISA were significantly decreased after EPO treatment,compared with the model group(P＜0.01).EPO significantly decreased the expression levels of Ang Ⅰ,VEGF-B,AT2R,ET-1,and TNF-α proteins in the aorta(P＜0.01)and significantly increased expression levels of Ang Ⅱ,CD31,and endothelial NO synthase proteins(P＜0.01).Conclusions EPO may ameliorate vascular endothelial injury in PCOS model rats by inhibiting the RAS signaling pathway and by overactivation of the ACE/Ang Ⅱ/AT1 axis.

Objective:To investigate the prognostic value and safety of thoracic radiotherapy in patients with synchronous oligometastatic, driver gene-negative non-small cell lung cancer (NSCLC) receiving immune checkpoint inhibitors (ICIs) as first-line treatment.Methods:Data were retrospectively collected from 55 patients diagnosed with synchronous oligometastatic, driver gene-negative NSCLC who received first-line ICIs from January 2017 to March 2022. These patients were categorized into two groups based on the administration of thoracic radiotherapy: the thoracic radiotherapy group ( n = 27) and the non-thoracic radiotherapy group ( n = 28). Comparative analyses were conducted to evaluate survival outcomes and safety profiles between the two groups. Results:Among the 55 patients, 27 (49.1%) received thoracic radiotherapy. The median follow-up time was 37.0 months (2.2-76.7 months). Patients in the thoracic radiotherapy group exhibited significantly improved median overall survival (OS: 53.4 vs. 21.3 months, P = 0.049) and median progression-free survival (PFS: 13.6 vs. 8.3 months, χ2=4.11, P = 0.043) compared to those in the non-thoracic radiotherapy group. Multivariate Cox regression analysis identified thoracic radiotherapy as an independent prognostic factor for OS ( HR = 0.39, 95% CI: 0.17-0.90, P = 0.027) and PFS ( HR = 0.53, 95% CI: 0.28-0.99, P = 0.046). The most common grade 3 or higher toxicity was bone marrow suppression, occurring in seven patients (12.7%). There was no significant difference between both groups in the incidence of grade 3 or higher treatment-related adverse events, including pneumonitis. Conclusion:In patients with driver gene-negative, synchronous oligometastatic NSCLC, first-line immunotherapy combined with thoracic radiotherapy may improve survival outcomes without increasing the incidence of severe treatment-related adverse events. Further large-scale, randomized prospective trials are needed to verify the findings of this study.

Recent studies have shown that the formation of the primary cilium is associated with a specific cellular organelle known as the midbody remnant(MBR),which is a point-like organelle formed by shedding of the midbody at the end of mitosis.MBRs move along the cell surface close to the center body and regulate it to form primary cilia at the top of the centriole.Primary cilia can act as an organelle to inhibit tumorigenesis,and it is lost in a variety of tumors.Studies have shown that the accumulation of MBRs in tumor cells affects ciliogenesis;in addition,both MBRs and primary cilia are degraded in tumor cells through the autophagy pathway,and MBRs can also transfer tumor signaling pathway factors to primary cilia affecting tumorigenesis.In this article,the basic structure and the formation process of MBR and primary cilia are reviewed and the mechanism of MBRs regulating ciliogenesis is elaborated.The significance of MBR-mediated ciliogenesis in tumorigenesis and its potential as a target for cancer treatment are discussed.

Objective:To verify the effect of Fu′s massage combined with physical therapy technology in rapidly relieving neck and low back pain caused by long-haul flight.Methods:Forty-two male volunteers were divided into 8, 12, 16, 24 and 48 h groups according to the simulated flying hours. After the completion of the simulated long-haul flight, the 5 groups of volunteers were immediately treated with Fu′s massage combined with physical factors for neck and low back pain. The Visual Analogue Scale (VAS) was used to evaluate the cervical and lumbar pain of volunteers after simulated flight and after treatment, and the treatment effect was before treatment analyzed.Results:There were significant differences in the VAS scores of cervical and lumbar regions before treatment among volunteers with different flying hours ( H=-30.15, -28.25, both P<0.001). The VAS scores of cervical and lumbar regions of volunteers in the 24 h and 48 h groups were higher than those in the 8 h group ( P=0.002, <0.001, =0.002, <0.001). The VAS scores of cervical and lumbar regions of volunteers in the 48 h group were higher than those in the 12 h group ( P=0.016, 0.001). The VAS score of cervical region of volunteers in the 48 h group was higher than that in the 16 h group ( P=0.033). After the intervention of Fu's massage combined with physical therapy, the VAS scores of cervical and lumbar regions in each group were lower than those before treatment, and the differences were significant ( t/ Z=-3.00-17.00, all P<0.05 or 0.01). Conclusions:Fu′s massage manipulation combined with physical treatment can effectively relieve the neck and low back pain caused by long-haul flight, which can be widely used as a relief method.

Objective To compare the predictive value of ORBIT score and HAS-BLED score for bleeding risk after warfarin anticoagulation following heart valve replacement. Methods The clinical data of 304 patients who underwent heart valve replacement and required warfarin anticoagulation therapy were retrospectively analyzed. The patients were stratified and grouped based on the ORBIT score and HAS-BLED score. The correlation between risk stratification based on different scores and postoperative bleeding events during warfarin anticoagulation was analyzed. The consistency of risk stratification between the two scoring methods and their predictive value for bleeding events were compared. Results Among 304 patients, there were 32 bleeding patients and 272 non-bleeding patients. The postoperative ORBIT and HAS-BLED scores of the bleeding patients were higher than those of non-bleeding patients(P < 0.05). The bleeding risk of medium and high-risk patients based on the ORBIT score was 6.092 (95%CI, 2.694 to 13.775) times and 9.373 (95%CI, 1.465 to 59.943) times higher than that of low-risk patients, respectively. The bleeding risk of medium and high-risk patients based on the HAS-BLED score was 3.750 (95%CI, 1.383 to 10.166) times and 14.250 (95%CI, 5.489 to 36.995) times higher than that of low-risk patients, respectively. The analysis of the receiver operating characteristic curve showed that the area under the AUC (95%CI, 0.589 0.698 9) of ORBIT score for predicting the risk of postoperative warfarin anticoagulation bleeding was 0.646 (95%CI, 0.589 to 0.699), with a sensitivity of 46.88% and a specificity of 87.87%, and an optimal cutoff value of 3 points. The AUC of HAS-BLED score predicting the risk of postoperative anticoagulation bleeding with warfarin was 0.768 (95%CI, 0.717 to 0.814), with a sensitivity of 75.00% and a specificity of 69.85%, and an optimal cutoff value of 2 points. The Delong test results showed that there was a statistically significant difference in AUC between the two scores (D=0.122; 95%CI, 0.001 to 0.245; Z=1.962; P < 0.05). Conclusion Both ORBIT score and HAS-BLED score have certain predictive value for bleeding risk during warfarin anticoagulation after heart valve replacement, but the predictive efficiency of HAS-BLED score is better.
