The primary chemical components of Astragalus membranaceus include polysaccharides, saponins, flavonoids, and amino acids. Recent studies have shown that Astragalus membranaceus has multiple functions, including improving immune function and exerting antioxidative, anti-radiation, anti-tumor, antibacterial, antiviral, and hormone-like effects. Astragalus membranaceus and its extracts are widely used in clinical practice because they have obvious therapeutic effects against various autoimmune diseases and relatively less adverse reaction. Multiple sclerosis (MS) is an autoimmune disease of central nervous system (CNS), which mainly caused by immune disorder that leads to inflammatory demyelination, inflammatory cell infiltration, and axonal degeneration in the CNS. In this review, the authors analyzed the clinical manifestations of MS and experimental autoimmune encephalomyelitis (EAE) and focused on the efficacy of Astragalus membranaceus and its chemical components in the treatment of MS/EAE.

Multiple sclerosis(MS) shows the pathological characteristics of "inflammatory injury of white matter" and "myelin repair disability" in the central nervous system(CNS). It is very essential for MS treatment and reduction of disease burden to strengthen repair, improve function, and reduce disability. Accordingly, different from the simple immunosuppression, we believe that key to strengthening remyelination and maintaining the "damage-repair" homeostasis of tissue is to change the current one-way immunosuppression strategy and achieve the "moderate pro-inflammation-effective inflammation removal" homeostasis. Traditional Chinese medicine shows huge potential in this strategy. Through literature research, this study summarized the research on remyelination, discussed the "mode-rate pro-inflammation-effective inflammation removal" homeostasis and the "damage-repair" homeostasis based on microglia, and summed up the key links in remyelination in MS. This review is expected to lay a theoretical basis for improving the function of MS patients and guide the application of traditional Chinese medicine.

Objective: To investigate the pathological characteristics and clinical prognosis of nodular sclerosis grade 2 of classic Hodgkin's lymphoma (cHL-NS2) in our cancer center. Methods: A retrospective collection of 23 cases of cHL-NS2 admitted in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from July 2008 to April 2019 was performed. Fifty-five cases of nodular sclerosis grade 1 of classical Hodgkin's lymphoma (cHL-NS1) during the same period were selected as control group. Survival curves were plotted using the Kaplan-Meier method, and Cox regression model was used to analyze the influencing factors for survival. Results: The median age of 23 cases of cHL-NS2 was 30 years old. Five cases had extra nodal invasion, and 19 cases were Ⅰ-Ⅱ stage based on Ann Arbor system. The pathological morphology of cHL-NS2 showed that the lymph node structure was completely destroyed and was divided into nodules by thick collagen. The tumor cells in the nodules were abundant and proliferated in sheets. The boundaries between the tumor cells were not clear. The incidence of tumor necrosis in cHL-NS2 was 43.5% (10/23), which was significantly higher than 18.2% (10/55) in cHL-NS1 (P=0.040). The 3-year progression-free survival (PFS) rate of patients in the cHL-NS2 group was 58.1%, which was significantly lower than 89.7% in the cHL-NS1 group (P=0.002). In all of 78 cases, the 3-year PFS rate of patients who did not obtain complete response (CR) was 67.1%, which was significantly lower than 92.2% in patients who achieved CR (P=0.030). Multivariate Cox regression analysis demonstrated that both cHL-NS2 and failure to obtain CR by first-line treatment were independent indicators for short PFS time (P<0.05). Conclusions: In cHL-NS2, the morphology of tumor cells are diverse, and tumor necrosis can be easily found. Under the current first-line treatments of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP), cHL-NS2 is an independent indicator for worse PFS.

BACKGROUND: Classical Hodgkin lymphoma (cHL) is a clinicopathologically unique, aggressive lymphoma arising from germinal center B-cells and is one of the most curable hematological malignancies. This study aimed to determine the clinical course, treatment regimens, response rates, and survival data of patients diagnosed with cHL in a tertiary center. METHODS: A retrospective review was conducted to include patients with a diagnosis of cHL from 2013 to 2017. Data of demographic and clinical characteristics, treatment regimens, and outcomes were collected and analyzed. RESULTS: We recruited 94 patients with a median age of 27.0 [interquartile range (IQR), 12] years. Most of the patients were male (61.7%) and 73.4% were ethnic Malay. Nodular sclerosis was the most common histology (77.6%), followed by mixed cellularity (6.4%) and others (16%). The median follow-up time was 28.0 (IQR, 32) months. All patients received chemotherapy but only 13.8% received radiotherapy as consolidation. The doxorubicin-bleomycin-vinblastine-dacarbazine regimen was the most common (85.1%), followed by the escalated bleomycin-etoposide-doxorubicin-cyclophosphamide-vincristineprednisolone-procarbazine regimen (14.9%). Following treatment, 76.1% of patients achieved complete response. The 2-year overall survival (OS) and progression-free survival (PFS) of the entire cohort were 96.5% and 71.1%, respectively. The 2-year OS and PFS for advanced-stage disease were 93.9% and 62.8%, compared to 100% and 82.7% for early-stage disease, respectively (P=0.252 and P=0.052, respectively). CONCLUSION: This study provides insight into the clinical presentation and treatment outcomes among patients with cHL in Malaysia. A longer study duration is required to identify OS and PFS benefits and treatment-related complications for different chemotherapeutic regimens.

Epilepsy surgery that eliminates the epileptogenic focus or disconnects the epileptic network has the potential to significantly improve seizure control in patients with medically intractable epilepsy. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) has been an established option for epilepsy surgery since the US Food and Drug Administration cleared the use of MRgLITT in neurosurgery in 2007. MRgLITT is an ablative stereotactic procedure utilizing heat that is converted from laser energy, and the temperature of the tissue is monitored in real-time by MR thermography. Real-time quantitative thermal monitoring enables titration of laser energy for cellular injury, and it also estimates the extent of tissue damage. MRgLITT is applicable for lesion ablation in cases that the epileptogenic foci are localized and/or deep-seated such as in the mesial temporal lobe epilepsy and hypothalamic hamartoma. Seizure-free outcomes after MRgLITT are comparable to those of open surgery in well-selected patients such as those with mesial temporal sclerosis. Particularly in patients with hypothalamic hamartoma. In addition, MRgLITT can also be applied to ablate multiple discrete lesions of focal cortical dysplasia and tuberous sclerosis complex without the need for multiple craniotomies, as well as disconnection surgery such as corpus callosotomy. Careful planning of the target, the optimal trajectory of the laser probe, and the appropriate parameters for energy delivery are paramount to improve the seizure outcome and to reduce the complication caused by the thermal damage to the surrounding critical structures.

Multiple Sclerosis (MS) is a chronic disabling neuroinflammatory disease. Psychiatric manifestations have a high prevalence in MS patients and may worsen the illness progression and the patients’ quality of life (QoL). Depression is a highly prevalent condition in MS patients, associated with poorer adherence to treatment, decreased functional status and QoL, and increased suicide risk. Diagnosis and treatment of this disorder is challenging because of symptom overlap. Other prevalent psychiatric comorbidities are anxiety disorders, bipolar disorder, psychotic disorders, substance misuse and personality disorders. As the illness progresses, personality changes can happen, as well as affect abnormalities. Cognitive changes occur frequently in MS patients, and affect features like processing speed, attention, learning, memory, visual spatial capabilities, and some language deficits. Disease-modifying treatments may reduce cognitive impairment because of their container action on the brain’s lesion burden. Other QoL determinants such as fatigue, pain, sexual dysfunction, exercise, resilience and social support should be taken into account, in order to promote the individuals’ well-being. Further studies are needed in order to elucidate the effectiveness of pharmacotherapy and more neuroimaging studies are required to clarify the relationship between structural changes and psychiatric comorbidities.
