Uveal melanoma(UM)is the most common primary intraocular malignancy in adults, characterized by high invasiveness and unique metastatic biological features. Although local treatments(such as proton beam therapy and brachytherapy)can effectively control the primary lesion, approximately 50% of patients eventually develop distant metastasis, with the liver being the primary target organ(occurring in 90% of cases). This highlights a paradigm shift in treatment focus from mere local control to systemic prevention and management. For metastatic UM(mUM), current treatment strategies encompass biomarker-guided molecular targeted therapy, immunotherapy(including Tebentafusp, vaccines, and oncolytic virus therapy), and liver-directed therapy. Focusing on the synergy between local and systemic prevention and control, this article systematically elaborates on the precision local treatment for primary UM, the decision-making pathway for systemic treatment of metastatic UM based on molecular subtyping, the integration of local and systemic therapies for liver metastases, and the translational value of nanomedicine in addressing therapeutic bottlenecks. It provides insights for optimizing clinical management of mUM and developing novel therapeutic strategies.

Objective To systematically evaluate the efficacy of traditional Chinese medicine(TCM)in the treatment of recurrent spontaneous abortion and their regulatory effects of levels of peripheral blood Th17 cells and Treg cells.Methods Computer retrieval of CNKI,WanFang,VIP,SinoMed,FMRS,PubMed,Cochrane Library,Embase,Web of science and other databases were carried out.RCTS related to the regulation of Th17 and Treg cells by TCM in the treatment of recurrent spontaneous abortion,published from the establishment of the database to June 2023 were screened.Two reviewers evaluated the quality of the literature according to the Cochrane handbook.RevMan5.4 software was used for Meta-Analysis.Results A total of 10 studies that involved 1 052 patients were included.The Meta-Analysis results showed that compared to the control group,the effective rate[RR=1.20,95%CI(1.11,1.30),P＜0.000 01],live birth rate[RR=1.32,95%CI(1.16,1.50),P＜0.000 01]and the reduction of adverse drug reactions[RR=0.34,95%CI(0.14,0.83),P=0.02]were significantly improved by the intervention of TCM.After treatment with TCM,the expression of Th17 cells was decreased[MD=-0.71,95%CI(-1.01,-0.41),P＜0.000 01],and the expression of Treg cells was increased[SMD=1.21,95%CI(0.80,1.62),P＜0.000 01].The ratio of Th17/Treg cells was decreased[SMD=-2.62,95%CI(-4.09,-1.14),P=0.000 5].Conclusion TCM used for post-pregnancy or before and after pregnancy can significantly improve the clinical symptoms and live birth rate of patients with recurrent spontaneous abortion,wihch showed high safety.Moreover,TCM can reduce the expression of Th17 cells,up-regulate the expression of Treg cells and regulate the immune balance of Th17/Treg cells,which is conducive to embryonic development after pregnancy.

Objective To investigate the predictive value of preoperative blood inflammatory markers for the recurrence risk in patients with basal cell carcinoma(BCC).Methods A total of 225 patients with BCC were divided into the high-risk recurrence group(155 cases)and the low-risk recurrence group(70 cases).General information and preoperative hematological indicators were collected in the two groups of patients.The neutrophil-to-lymphocyte ratio(NLR),lymphocyte-to-monocyte ratio(LMR),systemic inflammation marker(SIM)and platelet-to-lymphocyte ratio(PLR)were calculated.Receiver operating characteristic(ROC)curves were used to determine the predictive value of hematological markers with statistically significant differences between the two groups for BCC recurrence and to establish optimal cutoff values.Univariate and multivariate Logistic regression analyses were conducted to identify factors influencing BCC recurrence.A multivariate Logistic regression model was established to predict the recurrence risk of BCC.Area under the curve(AUC)and the Hosmer-Lemeshow test were used to evaluate the prediction efficiency and goodness-of-fit of the model.Results ROC analysis identified that optimal cutoff values for LMR and SIM were 5.12 and 0.86,respectively.Univariate Logistic regression analysis showed that LMR,SIM,ulceration at the primary tumor site,UV exposure and tumor maximum diameter were factors influencing BCC recurrence.Multivariate Logistic regression revealed that SIM≥0.86,tumor maximum diameter≥2.0 cm and UV exposure were risk factors for BCC recurrence,while LMR≥5.12 had a protective effect.The Logistic prediction model for BCC recurrence risk was Logit(P)=-1.598-1.517×LMR+1.323×SIM+2.406×UV exposure+3.465×tumor maximum diameter,with good model fit(P=0.725)and an AUC of 0.869(95%CI:0.822-0.917)for predicting BCC recurrence risk.Conclusion Monitoring preoperative LMR and SIM levels can assist in assessing the risk of recurrence in BCC patients and provide important guidance for clinical decision-making.

Purpose To investigate the difference of resting-state functional connectivity density(FCD)between chronic primary insomnia patients and healthy controls via resting state functional magnetic resonance imaging(rs-fMRI).Materials and Methods All rs-fMRI data of 35 patients with chronic primary insomnia from Xidian Group Hospital and Xi'an Encephalopathy Hospital of Traditional Chinese Medicine,and 35 healthy controls were prospectively collected from August 2020 to December 2021.The voxel-wise FCD approach was applied to explore the differences of whole-brain functional networks between chronic primary insomnia patients and healthy controls.The relationships between FCD value and Pittsburgh sleep quality index,self-rating scale of sleep,insomnia severity index,self-rating anxiety scale and self-rating depression scale in primary insomnia patients were investigated,respectively.Results Compared with healthy controls,the decreased FCD values were showed in the right insula,bilateral anterior cingulate gyrus,left orbitofrontal middle gyrus,left dorsolateral superior frontal gyrus,right medial superior frontal gyrus and bilateral thalamus(t<-5.271,Padjust<0.05),while the increased FCD values showed in the right superior temporal gyrus,bilateral middle temporal gyrus,bilateral precuneus and left posterior cingulate gyrus(t>4.379,Padjust<0.05)in the chronic primary insomnia patients group.The FCD values of bilateral thalamus(r=-0.620,P<0.001;r=-0.562,P<0.005)and right insula(r=-0.651,P<0.001)were negatively correlated with insomnia severity index in the chronic primary insomnia patients group,respectively.Conclusion The extensive functional connectivity abnormalities are observed in primary insomnia patients via FCD analysis.These findings explain the neural mechanisms of underlying emotional regulation and cognitive impairment in chronic insomnia from the perspective of functional integration and functional separation.

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Fat accumulation "sensitizes" the liver to insult and leads to nonalcoholic steatohepatitis (NASH). G protein-coupled receptor 35 (GPR35) is involved in metabolic stresses, but its role in NAFLD is unknown. We report that hepatocyte GPR35 mitigates NASH by regulating hepatic cholesterol homeostasis. Specifically, we found that GPR35 overexpression in hepatocytes protected against high-fat/cholesterol/fructose (HFCF) diet-induced steatohepatitis, whereas loss of GPR35 had the opposite effect. Administration of the GPR35 agonist kynurenic acid (Kyna) suppressed HFCF diet-induced steatohepatitis in mice. Kyna/GPR35 induced expression of StAR-related lipid transfer protein 4 (STARD4) through the ERK1/2 signaling pathway, ultimately resulting in hepatic cholesterol esterification and bile acid synthesis (BAS). The overexpression of STARD4 increased the expression of the BAS rate-limiting enzymes cytochrome P450 family 7 subfamily A member 1 (CYP7A1) and CYP8B1, promoting the conversion of cholesterol to bile acid. The protective effect induced by GPR35 overexpression in hepatocytes disappeared in hepatocyte STARD4-knockdown mice. STARD4 overexpression in hepatocytes reversed the aggravation of HFCF diet-induced steatohepatitis caused by the loss of GPR35 expression in hepatocytes in mice. Our findings indicate that the GPR35-STARD4 axis is a promising therapeutic target for NAFLD.

  Objective  To evaluate the clinical and paraclinical features of Chinese patients with anti- LGI1 encephalitis.  Methods  Patients with memory deficits, psychiatric symptoms, seizures or altered level of consciousness, suspicious of encephalitis, at presentation to Peking Union Medical College Hospital were recruited between July 2013 and January 2018, and tested for anti-LGI1 antibodies in their serum and/or cerebrospinal fluid(CSF) samples. Patients with anti-LGI1 antibodies were enrolled. The demographic characteristics, clinical manifestations, laboratory examination results, neuroimaging features, immunotherapy, follow-up practices and outcomes for included patients were registered and analyzed.  Results  The study enrolled 120 patients, of whom 66.7% were male. The median age was 61 years (interquartile range [IQR]: 49-66 years). Seizures(65.0%) were the most common initial symptoms. Most patients developed seizures (95.0%), including faciobrachial dystonic seizures (54.2%), memory deficits (92.5%), and psychiatric symptoms (69.1%). Brain MRI and ¹⁸F-FDG PET / CT showed that the lesions were mainly located in unilateral or bilateral medial temporal lobes, and (or) basal ganglia. Of the patients, 95.0% received intravenous immunoglobulin (IVIg) or corticosteroids, 47.5% received mycophenolate mofetil as long-term immunotherapy, and no one received second-line immunotherapy. The median follow-up was 34.2 months(IQR: 22.0-45.6 months). 91.2% had a good outcome (modified Rankin Scale score≤2 points). Residual mild memory deficits were present in 47.8% of the patients. Nine deaths were documented. Relapses occurred in 24.8% of the patients in the first year. In total, 24 (20%)cases were young patients(onset age ≤45 years).There were fewer males among the younger patients(37.5% vs. 74.0%, P < 0.01). Besides, there were fewer younger patients with psychiatric symptoms(50.0% vs. 74.0%, P=0.02), hyponatremia(33.3% vs. 68.8%, P < 0.01), and abnormalities on brain ¹⁸F-FDG PET/CT(20.8% vs. 47.9%, P=0.02). The relapse-free survival rate was significantly higher in the young patients.  Conclusions  Elderly males were predominant in patients with anti-LGI1 encephalitis. Most patients developed symptoms of limbic encephalitis and/or FDBS during the disease course. Several patients were young adults and lacked typical symptoms. Neuroimaging features were consistent with the involvement of limbic system or basal ganglia. Patients with anti-LGI1 encephalitis respond well to immunotherapy, irrespective of the age.

Objective To analyze the clinical and histology characteristics of a patient with frontal lobe epilepsy diagnosed with mild malformation of cortical development with oligodendroglial hyperplasia, and to recognize the new neuropathological entity. Methods Clinical history, seizure types, neuroimaging, electroencephalography as well as macroscope, histology and immunohistochemistry characteristics were collected from a frontal lobe epilepsy patient and were compared with cases from literature. Results It was a female patient aged 16 years with 12 years history of epilepsy. The seizures manifested as episodes of conscious loss with automatism including grope and voice lasting for seconds. About 10 episodes a day were found and sometimes with secondary generalized tonic-clonic seizures. MRI showed blurring of grey-white matter interface in left orbital frontal cortex. Video-encephalography revealed left frontal lobe origin of seizures. So left prefrontal lobe was removed. Histology showed almost normal cortex neuropil and neurons. Blurring of grey-white interface in some area with patches of proliferation of oligodendrocytes in the corresponding sub-cortical white matter was found. The density of oligodendrocytes was significantly higher in sub-cortical than in deep white matter both shown in HE and Oligo-2 staining. Obvious oligodendrocytes increase and satellite phenomenon in deep cortical layer as well as increased ectopic neurons in sub-cortical white matter were found in the lesion. In proliferation area, there were some nuclei stained with Ki-67, but not as high as tumor. Subsequent follow up for two years proved the operation efficacy and benign prognosis. Conclusions There are special and undiscovered histopathological entities in epilepsy etiology. Although known as grey matter disease, white matter pathology plays an important role in epilepsy pathophysiology which needs further research.
