ObjectiveTo analyze the differences in color， odor and volatile components of Citri Reticulatae Pericarpium（CRP） before and after being stir-fried with Halloysitum Rubrum， and to explore the material basis of enhancing the effect of strengthening spleen after processing and the scientific connotation of decoction pieces processed with Halloysitum Rubrum as the auxiliary material. MethodsThe volatile components of the samples before and after processing were identified and relatively quantified by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and the volatile components were analyzed by principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）. According to the principle of variable importance in the projection（VIP） value>1.5， volatile differential components before and after processing were screened. And combined with intelligent sensory technologies such as colorimeter and electronic nose， the chroma and odor information of CRP before and after being stir-fried with Halloysitum Rubrum were identified. Pearson correlation analysis was used to explore the correlation between volatile differential components and chroma values. ResultsA total of 112 volatile components were identified from CRP and CRP stir-fried with Halloysitum Rubrum， of which 84 were from CRP and 97 were from CRP stir-fried with Halloysitum Rubrum. And 7 differential components were selected， including α-pinene， β-myrcene， linalool， sabinene， ocimene isomer mixture， A-ocimene， and δ-elemene. After being processed with Halloysitum Rubrum， the brightness value（L^*）， yellow-blue value（b^*） and total chromatic value（E^*_ab） of CRP were decreased（P<0.01）， and red-green value（a^*） was increased（P<0.01）， the response values of S4， S5， S10 and S13 sensors were significantly increased（P<0.05）， and the response values of S3 and S8 sensors were significantly decreased（P<0.05）. Correlation analysis showed that α-pinene and β-myrcene were negatively correlated with L^* and E^*_ab， but positively correlated with a^*. Sabinene was positively correlated with L^* and E^*_ab. Linalool was positively correlated with L^* and E^*_ab， and negatively correlated with a^*. The ocimene isomer mixture was positively correlated with the L^*. ConclusionAfter being processed with Halloysitum Rubrum， the appearance color， odor and volatile components of CRP change significantly， and α-pinene， β-myrcene， sabinene， linalool and A-ocimene are the characteristic volatile components before and after processing， which can provide references for the quality evaluation and clinical application of CRP and its processed products.

Objective:To evaluate the efficacy and safety of combining third-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) with brain radiotherapy in patients with newly diagnosed EGFR mutation-positive non-small cell lung cancer (NSCLC) with brain metastases. Methods:A retrospective analysis was performed on the clinical data of patients with newly diagnosed EGFR-mutant NSCLC with brain metastases who received first-line treatment with third-generation EGFR-TKI with or without brain radiotherapy at the Fourth Affiliated Hospital of Guangxi Medical University between January 2018 and December 2022. Patients treated with EGFR-TKI plus brain radiotherapy were assigned to the combination group, while those treated with EGFR-TKI alone were assigned to the monotherapy group. Intracranial progression-free survival (iPFS), progression-free survival (PFS), overall survival (OS), intracranial disease control rate (iDCR), intracranial objective response rate (iORR), and adverse events were compared between groups. Subgroup analyses were performed according to EGFR exon 19 deletion (19del) and exon 21L858R mutation status. Survival was estimated using the Kaplan-Meier method, with the log-rank test applied for group comparisons and univariate analysis, while multivariate analysis was conducted using Cox proportional hazards regression model. Results:A total of 107 patients were included: 57 (53%) in the monotherapy group and 50 (47%) in the combination group. The combination therapy significantly improved iORR (80% vs. 60%, P=0.023), prolonged median OS (37.7 vs. 31.6 months, P=0.004), and extended median iPFS (21.8 vs. 16.7 months, P=0.018). The iDCR was 100% in both groups, and the difference in median PFS was not statistically significant (18.6 vs. 15.2 months, P=0.086). In the 19del subgroup ( n=53), patients in the combination group had longer OS ( P=0.028) and iPFS ( P=0.028). In the 21L858R subgroup ( n=54), the median OS was also longer in the combination group ( P=0.050). Multivariate analysis identified TKI monotherapy and an Eastern Cooperative Oncology Group (ECOG) performance status score=2 as independent adverse prognostic factors for iPFS, while TKI monotherapy, age ≥65 years, ECOG score=2, and >3 brain metastases were the independent adverse prognostic factors for OS. The incidence of adverse events did not differ significantly between groups (all P>0.05). Conclusions:First-line combination therapy with third-generation EGFR-TKI and cranial radiotherapy provides superior efficacy and acceptable safety compared with EGFR-TKI monotherapy in patients with EGFR-mutant lung adenocarcinoma and brain metastases. Both EGFR 19del and 21L858R mutation subgroups benefit from the combined treatment approach.

Objective:To explore the efficacy and safety of olverembatinib in treatment of chronic myeloid leukemia (CML) progressed to acute lymphoblastic leukemia with D241E mutation.Methods:The diagnosis and treatment of a patient with D241E mutant CML progressed to acute lymphoblastic leukemia admitted to the Fourth People's Hospital of Jinan in December 2018 were retrospectively analyzed, and relevant literature was reviewed.Results:The patient was a 47-year-old female, and her blood test result was abnormal during physical examination. She was diagnosed as CML and received treatment with imatinib and dasatinib for 2 years. The disease progressed to philadelphia chromosome (Ph)-positive acute B-lymphoblastic leukemia with BCR-ABL mutation (a D241E mutation). After 3 courses of chemotherapy combined with a targeted drug (ponatinib), the patient achieved complete remission, while the minimal residual disease continued to be positive. The patient received 1 course of chemotherapy combined with olverembatinib from the 4th course of treatment. After olverembatinib monotherapy maintenance therapy for 36 months, the patient achieved molecular complete remission with minimal residual disease. The patient developed complications such as skin pigmentation and elevated lipid levels, but all complications were tolerable.Conclusions:The application of olverembatinib in D241E mutant CML progressed to acute lymphoblastic leukemia can help patients obtain sustained molecular biological remission and good safety.

The clinical phenotype heterogeneity of epilepsy patients with ADGRV1 gene mutation is significant, ranging from self limiting febrile seizures to developmental epileptic encephalopathy, even causing sudden epileptic death. A case of infantile epileptic spasms syndrome with a novel heterozygous variant of the ADGRV1 gene c.4100C>A (p.Thr1367Lys) was reported in this article. The site of this variant had not been reported yet, and the clinical manifestations of the child mainly included epileptic spasms (first onset at 4 months old), mild growth and development delay, highly irregular video electroencephalogram, and effective treatment with adrenocorticotropic hormone.

Premature ovarian insufficiency(POI)is a disease that seriously affects the health and life of women,which is also one of the main causes of female infertility.The incidence of POI is increasing in recent years.The diagnostic criteria of POI are not uniform,and different diagnostic criteria have inconsistent thresholds for various indicators.Strict diagnostic criteria are more conducive to early detection and treatment of POI.At present,complementary and alternative therapies such as traditional Chinese medicine,acupuncture and moxibustion are widely used in the treatment of POI.This article reviewed the recent studies on the complementary and alternative therapy of traditional Chinese medicine in the treatment of POI,and finds that the dialectical treatment of traditional Chinese medicine is based on the perspective of traditional Chinese medicine theory and puts forward corresponding treatment plans for different dialectical types.For example,treatment from the kidney,tonifying kidney filling essence,regulating chongren;Treatment from the liver,soothing the liver,regulating qi,nourishing blood and softening the liver;Treatment from the heart and spleen,nourishing Yangming,tonifying the spleen and nourishing the heart.In terms of acupuncture treatment,regulating menstruation and promoting pregnancy and regulating the conception vessel and toning the governor vessel and toning the kidney are often used to treat POI.In addition,moxibustion regulates body function by stimulating the bladder meridian and conception vessel and governor vessel acupoints.Other methods,such as ear acupoint bean-pressing,acupoint thread-embedding and acupoint injection,have also shown potential in the treatment of POI.This article summarizes the role and characteristics of traditional Chinese medicine in the treatment of POI,in order to provide ideas and basis for clinical treatment of POI.

Objective To compare the image quality of readout-segmented diffusion weighted imaging(RESOLVE-DWI)and integrated slice-by-slice shimming diffusion weighted imaging(iShim-DWI)in patients with nasopharyngeal carcinoma.Methods A retrospective study was conducted on 26 patients with nasopharyngeal carcinoma confirmed by pathology.The imaging data included RESOLVE-DWI and iShim-DWI.The signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the two sequences were compared by one deputy chief imaging technician.And two experienced radiologists used the 5-point scoring scheme to compare the lesion clarity,image artifacts,and antideformation ability of the two sequences,repectively.Results The SNR and CNR of the iShim-DWI sequence were significantly higher than those of RESOLVE-DWI sequence(P＜0.01).While the subjective scores of lesion clarity,image artifacts,and antideformation ability on RESOLVE-DWI were significantly better than those of iShim-DWI,and the differences were statistically significant(P＜0.01).Conclusion Both RESOLVE-DWI and iShim-DWI obtained good images.With sufficient SNR and CNR,RESOLVE-DWI has clearer lesions and surrounding structures,higher image resolution,fewer artifacts,and better antideformation ability,thus providing clinical advantages in evaluating patients with good physical tolerance.

Myasthenia gravis(MG)is an autoimmune disease characterized primarily by skeletal muscle weakness and,in severe cases,respiratory involvement.Western medical treatment predominantly relies on immunosuppressants,but long-term administration often leads to notable side effects.In contrast,traditional Chinese medicine(TCM)offers the advantage of multi-target interventions.However,the pathogenesis of MG has not been fully elucidated,and the establishment of animal models that accurately reflect the clinical characteristics of both Chinese and Western medicine is essential for mechanism research and new drug development.This paper systematically reviews the etiology and pathogenesis,diagnostic criteria,and progress of animal model research for MG from both Chinese and Western medicine perspectives.In Western medicine,the pathogenesis of MG is closely related to genetic susceptibility,environmental factors,and autoantibody-mediated postsynaptic membrane damage.In TCM,MG is classified under the category of"flaccidity syndrome",attributed to congenital deficiencies and acquired malnourishment.Western diagnostic criteria involve a combination of clinical symptoms,fatigue testing,serum antibody assays,and electrophysiological evaluation.In contrast,TCM diagnosis emphasizes the integration of primary and secondary symptoms with tongue and pulse pattern differentiation.Currently available animal models mainly include experimental autoimmune myasthenia gravis(EAMG)and passive transfer myasthenia gravis(PTMG).The Toredo acetylcholine receptor(AChR)induced EAMG model aligns well with Western diagnostic criteria,but poorly matches secondary symptoms in TCM.The synthetic AChR peptide model is widely used,but shows low conformity with TCM syndromes.Models induced by muscle-specific tyrosine kinase(MuSK),low-density lipoprotein receptor-related protein 4(LRP4),and transgenic models demonstrate high innovation but exhibit low clinical conformity.Evaluation of these models requires integration of behavioral,electrophysiological,and immunological indicators.However,a systematic framework for modelling TCM syndromes is still lacking.Future research should integrate TCM-based etiological modelling methods with the Western pathological mechanisms to construct disease-syndrome combination models.Additionally,it is crucial to establish a TCM syndrome evaluation system based on"validation by prescription",as well as to improve the scientific rigor and practicality of animal models by the incorporation of emerging technologies.This review provides a theoretical foundation for optimizing MG animal model design,advancing the research on the combination of Chinese and Western medicine,and supporting efficacy assessment and mechanism exploration of Chinese herbal prescriptions.
