Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

OBJECTIVES: To investigate the clinical characteristics and prognosis of infants and young children with basal ganglia infarction after minor head trauma (BGIMHT). METHODS: A retrospective analysis was conducted on the clinical data and follow-up results of children aged 28 days to 3 years with BGIMHT who were hospitalized at Children's Hospital of Soochow University from January 2011 to January 2022. RESULTS: A total of 45 cases of BGIMHT were included, with the most common symptom being limb movement disorders (96%, 43/45), followed by facioplegia (56%, 25/45). Cerebral imaging showed that 72% (31/43) had infarction accompanied by basal ganglia calcification. After conservative treatment, 42 children (93%) showed significant symptom improvement, while 3 children (7%) experienced recurrent strokes. The median follow-up time was 82 months (range: 17-141 months). At the last follow-up, 97% (29/30) had residual basal ganglia softening lesions. Among 29 cases participating in questionnaire follow-up, 66% (19/29) recovered normally, 17% (5/29) showed significant improvement in symptoms, and 17% (5/29) had poor improvement. According to the grading of the Global Burden of Disease Control Projects, only 1 child (3%) had severe sequelae. There were no significant differences in age at onset, gender, or presence of concomitant basal ganglia calcification between children with and without neurological sequelae (P>0.05). CONCLUSIONS The most common initial symptom of BGIMHT is limb movement disorder, and imaging results indicate that most children have concurrent intracranial calcifications. Most infarct lesions later transform into softening lesions, resulting in a generally good prognosis.

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with IgD multiple myeloma (MM). METHODS: The clinical data of 8 patients with IgD MM admitted to Gansu Provincial Hospital from September 2013 to February 2023 were collected, and their clinical characteristics and prognosis were retrospectively analyzed and summarized. RESULTS: Among the 8 enrolled patients, there were 4 males and 4 females, with a median age of 60 (44-74) years. All patients had symptoms of renal insufficiency and anemia. There were 3 cases of bone invasion, 3 cases of splenomegaly, 7 cases of IgD-λ type, and 1 case of IgD-κ type. FISH examination was performed in 7 cases, and 6 of them were positive for 1q21 . There were 6 cases in DS stage III and 2 cases in DS stage II; According to ISS staging, there were 6 cases in stage III, 1 case in stage II, and 1 case in stage I; According to R-ISS staging, there were 5 cases in stage III and 3 cases in stage II. All patients received bortezomib-based combination chemotherapy, with 1 case undergoing autologous stem cell transplantation (ASCT) and 2 cases receiving daratumumab in combination. The median treatment period was 6 (1-15) cycles. The short-term efficacy was evaluated after 4-6 courses of treatment. Among the 6 patients with assessable efficacy, 1 case experienced disease progression (PD), and 5 cases achieved complete remission (CR). The median follow-up time was 26 (11-33) months, and the median progression-free survival (PFS) and median overall survival (OS) of the patients were 11.25 (3-26) months and 18.5 (4-33) months, respectively. Among the 8 patients, 4 cases died. Among the deceased patients, 3 cases were in R-ISS stage III and 3 cases were 1q21 positive. 2 of the 5 patients with early CR died due to disease progression. CONCLUSION The incidence of IgD MM is low, the symptoms of early renal damage, blood system damage and bone erosion in IgD MM patients are obvious, and the median survival time is short. ASCT and / or daratumumab may bring lasting relief for IgD MM patients, but large-scale clinical studies are still needed.

OBJECTIVE: To analyze the clinical characteristics and prognosis of patients with T-cell large granular lymphocytic leukemia (T-LGLL). METHODS: The clinical data of 7 patients with T-LGLL in Gansu Provincial Hospital from March 2016 to June 2023 were analyzed retrospectively. RESULTS: Among the 7 patients, 5 were male and 2 were female, with a median age of 51(28-83) years old. At the onset of illness, 6 cases showed symptoms of fatigue and anemia, 4 cases had enlarged lymph nodes, and 5 cases had splenomegaly. Examination showed that 4 cases were antinuclear antibody(ANA) positive, 5 cases were anemia. The median hemoglobin (Hb) level was 83(61-151) g/L, the median white blood cell count (WBC) was 5.6(2.0-8.7)×10⁹ /L, and the median percentage of lymphocytes in peripheral blood was 66.2(13.9-89.1)%. There were 3 cases with extremely active bone marrow hyperplasia, 2 cases with active hyperplasia, and 2 cases with decreased hyperplasia. There were 5 cases with mild myelofibrosis (MF-1), and 1 case with moderate myelofibrosis (MF-2). The median percentage of T cells was 64.3 (31.5-80.6)%. 5 cases showed the classic immunophenotype (CD3 ⁺ CD4^- CD8 ⁺), 6 cases were CD57 ⁺, 3 cases were TCRα/β ⁺, and 3 cases were TCRγ/δ ⁺. TCRG rearrangement was detected in 5 cases.The median follow-up time was 55(4-87) months, one patient died of heart disease, and the other 6 patients are surviving. CONCLUSION The incidence of T-LGLL is low. The initial symptoms of T-LGLL include anemia, fatigue, lymph node enlargement, splenomegaly, and higher percentage of lymphocytes in peripheral blood, the percentage of abnormal T cells in bone marrow was significantly increased. Analysis of flow cytometric immunophenotyping, TCR gene rearrangement, and hot spot genes such as STAT3 and STAT5b, can improve the diagnostic accuracy.

Objective To explore the application value of fractional anisotropy(FA)analysis of RGB component transformation in different directions of fibers in substantia nigra in Parkinson's disease(PD).Methods There were 35 cases of PD and 37 cases of normal control group.After being performed by brain diffusion tensor imaging(DTI)scanning,the sequence was imported into 3DSlicense 5.6.0,and the diffusion module was used to implement pseudo color mapping based on FA,locate and segment substantia nigra,and use the substantia nigra mask as the tracking starting point.After forming tracing,fibers were imported into DTIANALYSIS 1.51,converting the RGB components into FA values for analysis,and visualized the analysis result.At the same time,fiber length,fiber density,and segmented FA point cloud percentage were compared.Results Compared with the normal group,the length of substantia nigra fibers in the PD group was shorter[(95.14±19.85)mm vs(115.99±21.39)mm,P＜0.01],and there was a statistical difference between the two groups.There was no statistical difference in fiber density[(0.07±0.05)/mm3 vs(0.10±0.12)/mm3,P＞0.05]between control group and PD group.The percentage of FA segment point clouds in the PD group was lower than that in the normal group at 0.9-1,but the principal component characteristics of the point cloud ratios in each FA segment were not significant.Conclusion Based on the transformation of RGB components into FA analysis,the length,density,and FA values of substantia nigra nerve fibers in PD patients can be quantified and visualized,providing a basis for the study of PD neural pathways.

Objective To explore the visualization effect of different walking fibers and anatomical positions of the basal nucleus in the postcentral gyrus based on the diffusion tensor imaging(DTI)fiber bundle of the precentral gyrus and internal capsule reconstruction model.Methods A set of diffusion tensor volume(DTV)data was used to visualize and export a mesh model by a 3DSlicense 5.6.2 software.The basal nucleus were reconstructed by 3DSlicense through T1W1 data from the same scan,and exported the mesh model,and thus imported the above model into DTIANALYSIS 1.51 software for visualization.By adjusting the RGB component threshold,the fiber bundles were screened to obtain fiber bundles that mainly run left and right,front and back,and up and down.The anatomical relationship between the fiber bundles and the basal nucleus was observed.Results The fiber bundles originating from the precentral gyrus were mainly distributed in the inner and lower parts,and run above and outside the basal nucleus;The fiber bundles that mainly run forward and backward are distributed on the outer side and run on the outer side of the basal nucleus;The fiber bundles that mainly run up and down were distributed in the upper and middle parts of the precentral gyrus,with some fibers running towards the hypothalamus.They intersect in the corpus callosum and ventral pons,and run along the posterior part of the space between the lentiform nucleus and the dorsal thalamus.Conclusion Based on the RGB components in DTI,fibers with different walking directions in the precentral gyrus can be screened to display their anatomical position relationship with the basal ganglia.

Objective : To investigate the diagnostic value of combined detection of folate receptor-positive circulat- ing tumor cells ( FR + -CTCs) and hemostatic function indicators in improving the diagnosis of gastrointestinal tumors ( GITs) metastasis． Methods: A retrospective analysis was conducted on the clinical data of 115 patients aged 18 to 80 years who were diagnosed with gastrointestinal tumors via pathology and received treatment，including data on FR + -CTCs，hemostatic function indicators，and pathological staging．The collected data encompassed FR + -CTCs levels，coagulation parameters，and pathological staging．Statistical analysis included t-tests，chi-square tests，fish- er ’s exact test，Logistic regression analysis，and receiver operating characteristic ( ROC) curves to assess the diag- nostic value of combined FR + -CTCs and coagulation parameters in detecting tumor metastasis． Results: FR + -CTCs levels and positive rates demonstrated significant associations with clinicopathological characteristics ( gender，histo- logical type，N staging) in GITs patients ( P＜0. 05) ．In patients with metastasis，elevated fibrinogen levels were observed．Adithonallly，platelet counts showed significant increases in N1 －N3 stages ( P＜0. 05) ．Logistic regres- sion analysis showed that PLT and antithrombin Ⅲ ( AT-Ⅲ) were independent risk factors for GITs metastasis ( P＜0. 05) ． The areas under the ROC curves for predicting GITs metastasis were 0. 678 ( 95% CI: 0. 540 - 0. 816) and 0. 664 ( 95% CI: 0. 512 －0. 815) ，respectively．When combining multiple factors，including FR + - CTCs，PLT，AT-Ⅲ , pathological type，FIB，TT，and gender，for the diagnosis of GITs metastasis，the AUC in- creased to 0. 757 ( 95% CI: 0. 621 －0. 893) ，indicating higher sensitivity and specificity compared to using each indicator alone． Conclusion The combined detection of FR + -CTCs and anticoagulation function indicators has a higher diagnostic value for the diagnosis of GITs，providing a valuable basis for the early diagnosis of GITs，espe- cially in metastasis surveillance．

Objective To observe the therapeutic effect and mechanism of Baoyuan Decoction for chronic heart failure model rat.Methods SD rats were randomly divided into blank group,model group,Baoyuan Decoction group,Captopril group,Baoyuan Decoction+CCT020312[protein kinase R-like endoplasmic reticulum kinase(PERK)activator]group,15 rats in each group.Except for the blank group,the rats in the other groups were induced by Adriamycin to construct a chronic heart failure model.After corresponding drug intervention,cardiac function indexes[left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS),brain natriuretic peptide(BNP),cardiac troponin I(cTnI)],inflammation-related factors[tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β)],oxidative stress factors[malondialdehyde(MDA),superoxide dismutase(SOD)]were detected in each group.Changes in apoptosis-related indicators[B-cell lymphoma 2(Bcl-2),B-cell lymphoma 2-associated X protein(Bax),Caspase-3]and PERK/transcription activator 4(ATF4)signaling pathway-related proteins glucose-regulated protein 78(GRP78),PERK,ATF4,C/EBP homologous protein(CHOP)levels.Results Compared with the blank group,LVEDD,BNP,cTnI,TNF-α,IL-1β,MDA levels,protein expression levels of Bax,Caspase-3,GRP78,PERK,ATF4,CHOP in the model group were significantly increased,LVEF,LVFS,SOD levels and Bcl-2 protein expression level were significantly decreased(all P＜0.05).Compared with the model group and Baoyuan Decoction+CCT020312 group,LVEDD,BNP,cTnI,TNF-α,IL-1β,MDA levels,protein expression levels of Bax,Caspase-3,GRP78,PERK,ATF4,CHOP in Baoyuan Decoction group and Captopril group were significantly decreased,LVEF,LVFS,SOD levels and Bcl-2 protein expression level were significantly increased(all P＜0.05).Compared with the Captopril group,there was no significant change in the above indexes(except CHOP protein expression level)in the Baoyuan Decoction group(P＞0.05).Conclusion Baoyuan Decoction can delay the progression of chronic heart failure rats,and its mechanism may be related to inhibiting the PERK/ATF4 signaling pathway to alleviate cardiomyocyte apoptosis,further reducing the degree of inflammatory response and oxidative stress,thereby promoting the repair of cardiac function and myocardial injury.
