Objective To observe the clinical manifestations of 3 cases with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease and anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis antibody overlapping syndrome (MNOS), aiming to expand the understanding of the clinical spectrum of such syndromes. Methods Retrospective analysis was performed on the data of 3 patients with MNOS who were positive for both MOG antibodies and NMDAR antibodies. Clinical features, neuroimaging characteristics, and outcomes were collected, and cell-based assay (CBA) technique was used for diagnosis. Results One case presented both positive MOG antibodies and NMDAR antibodies, but the clinical manifestations were typical symptoms of anti-NMDAR encephalitis. In one case, the clinical and cranial magnetic resonance imaging (MRI) features of demyelinating disease recurred after anti-NMDAR encephalitis, with atypical symptoms of MNOS such as numbness and weakness in limbs, blurred vision, and diplopia. The last case presented both positive MOG antibodies and NMDAR antibodies, but the clinical manifestations were typical symptoms of anti-NMDAR encephalitis. In MNOS, MOG antibody-associated disease and anti-NMDAR encephalitis may appear simultaneously or sequentially, with epilepsy being the most common symptom. Cranial MRI findings showed that the patients presented and mainly involved supratentorial lesions, which may also involve the brainstem, but no spinal cord lesions were found. All patients showed slightly abnormal cerebrospinal fluid. Patients showed a good response to first-line immunotherapy during the acute phase of the disease, with a favorable prognosis. But most patients were prone to relapse. Conclusion In MNOS patients, anti-NMDAR encephalitis may present with clinical and(or)MRI features of demyelinating disease simultaneously or sequentially. The clinical manifestations of patients are complex and diverse. Patients with atypical symptoms require to improving the understanding of MNOS and timely treatment.

This study reported a 50-year-old female patient who was diagnosed with anti-IgLON family member 5 (anti-IgLON5) antibody-related encephalopathy, presented with cognitive and sleep disorders, autonomic dysfunction and seizures, positive serum IgLON5 antibody but negative cerebrospinal fluid IgLON5 antibody, negative human leukocyte antigen (HLA) by genetic testing, and was diagnosed as anti-IgLON5 antibody-related encephalopathy. After hospital admission, the patient was given intravenous methylprednisolone combined with immunoglobulin immunotherapy, donepezil for improvement of cognition, sodium valproate and oxcarbazepine for prevention and treatment of epileptic seizures, and finally her symptoms improved significantly.

ObjectiveTo investigate the effect of Bufeitang on intestinal flora of rats with lung Qi-deficiency syndrome of chronic obstructive pulmonary disease（COPD）， and to explore the mechanism of traditional Chinese medicine in regulating intestinal flora and thus restoring the balance of lung-gut axis. MethodA total of 84 rats were randomly divided into 7 groups， including blank group， model group， fecal bacterial transplantation（FMT） group， dexamethasone group and low， medium and high dose groups of Bufeitang， 12 rats in each group. Except for the blank group， cigarette and sawdust fumigation combined with intratracheal instillation of lipopolysaccharide（LPS） were used to establish the COPD rat model with lung Qi-deficiency syndrome in all other groups. The low， medium and high dose groups of Bufeitang were intragastric administrated with Bufeitang（3.645， 7.29， 14.58 g·kg^-1）， the FMT group was given fecal bacteria liquid enema（10 mL·kg^-1）， dexamethasone group was given dexamethasone acetate tablet suspension by gavage（0.135 mg·kg^-1）， the blank group and model group were given equal amount of distilled water. Fresh feces were collected after 28 d of continuous intervention for 16S rRNA gene sequencing. Lung and colon tissues were stained with hematoxylin-eosin（HE） for pathomorphological observation， and enzyme-linked immunosorbent assay （ELISA） was performed to detect the contents of tumor necrosis factor-α（TNF-α） and interleukin-8（IL-8） in lung tissues. ResultCompared with the blank group， the model group showed severe abnormal lung tissue structure with alveolar atrophy and collapse accompanied by severe inflammatory cell infiltration. Compared with the model group， the extent of injury was significantly improved， and inflammatory cell infiltration was reduced with basically normal alveolar structure in the high dose group of Bufeitang. Compared with the blank group， the model group had severely abnormal colonic tissue structure， the epithelial cells in the mucosal layer were eroded and shed， the number of inflammatory cells increased， the submucosal layer was edematous and the gap was enlarged. Compared with the model group， the extent of damage was significantly improved in the medium and high dose groups of Bufeitang， the epithelial cells in the mucosal layer were neatly and closely arranged， with only a small amount of inflammatory cell infiltration and no significant degeneration. Compared with the blank group， the TNF-α and IL-8 levels of lung tissue in the model group were significantly increased（P<0.01）. Compared with the model group， the TNF-α and IL-8 levels of lung tissues in the low， medium and high dose groups of Bufeitang were significantly decreased（P<0.01）. Bufeitang significantly modulated the number of bacteria species as well as alpha and beta diversity of model rats， corrected the return of intestinal flora to normal abundance and diversity， and positively regulated 4 differential phyla（such as Firmicutes， Proteobacteria） and 13 differential genera（such as Turicibacter， Lactobacillus， Anaerobiospirillum， Intestinimonas） in COPD model rats with lung Qi-deficiency syndrome， and down-regulated 2 carbohydrate metabolic pathway functions， including the pentose phosphate pathway（non-oxidative branch） Ⅰ and the Calvin-Benson-Bassham cycle. ConclusionBufeitang can modulate the abundance and diversity of intestinal flora species， affect the function of metabolic pathways， repair the structure of lung and colon tissues， regulate the level of inflammatory factors， and thus improve COPD with lung Qi-deficiency syndrome. The mechanism may be related to its regulation of inflammation-related intestinal flora to restore the balance of lung-gut axis in COPD with lung Qi-deficiency syndrome.

As one of the hallmarks of cancer, metabolic reprogramming leads to cancer progression, and targeting glycolytic enzymes could be useful strategies for cancer therapy. By screening a small molecule library consisting of 1320 FDA-approved drugs, we found that penfluridol, an antipsychotic drug used to treat schizophrenia, could inhibit glycolysis and induce apoptosis in esophageal squamous cell carcinoma (ESCC). Gene profiling and Ingenuity Pathway Analysis suggested the important role of AMPK in action mechanism of penfluridol. By using drug affinity responsive target stability (DARTS) technology and proteomics, we identified phosphofructokinase, liver type (PFKL), a key enzyme in glycolysis, as a direct target of penfluridol. Penfluridol could not exhibit its anticancer property in PFKL-deficient cancer cells, illustrating that PFKL is essential for the bioactivity of penfluridol. High PFKL expression is correlated with advanced stages and poor survival of ESCC patients, and silencing of PFKL significantly suppressed tumor growth. Mechanistically, direct binding of penfluridol and PFKL inhibits glucose consumption, lactate and ATP production, leads to nuclear translocation of FOXO3a and subsequent transcriptional activation of BIM in an AMPK-dependent manner. Taken together, PFKL is a potential prognostic biomarker and therapeutic target in ESCC, and penfluridol may be a new therapeutic option for management of this lethal disease.

The cancer patients may experience ovarian dysfunction and lose their fertility after radiotherapy or chemotherapy. Therefore, the oncologists face problems of how to protect reproductive function and improve their life quality of young female patients. Ovarian tissue cryopreservation and transplantation (OTCT) could restore the female reproductive endocrine and is one of the main methods for fertility preservation. This method provides a new way for patients who are not suitable for fertility preservation by oocyte cryopreservation and embryo cryopreservation. In recent years, there are many heathy births by OTCT. But, this method also has deficiencies, such as ischemic atresia after transplantation before rebuilding blood supply and risk of reintroducing the malignant cells after retransplantation. This paper reviews the development of OTCT.

Objective To prepare SDF-1 α-loaded nanoliposome ( SNP )-SonoVue complex and investigate its tracing abilities, sustained-release property and effect on migration of bone marrow mesenchymal stem cells (BMSCs). Methods The SNP was prepared to detect its physical characteristics including particle size,zeta potential, morphology, encapsulation efficiency and drug loading.SNP-SonoVue was constructed to detect the sustained release situation of SNP and SNP-SonoVue after low frequency ultrasound ( LIFU ) irradiation, and the connection of SNP-SonoVue was observed by fluorescence microscope. Effects of SNP-SonoVue on migration of BMSCs were detected to evaluate its bioactivity. BMSCs were divided into 6 groups,including Group A: SDF-1α+ 1% serum medium;Group B: SNP- SonoVue+ 1% serum culture medium;Group C:SNP-SonoVue+ 1% serum culture medium + LIFU ( 1 MHz,0.5 W/cm2, expose 30 s stop 30 s, 4 min);Group D: BNP-SonoVue+1% serum medium;Group E:BNP-SonoVue+1% serum medium+LIFU ( 1 MHz, 0.5 W/cm2, expose 30 s stop 30 s, 4 min),Group F:PBS+1% serum culture medium (control group). Its tracing abilitie were investigated in vitro. Results The average particle size of SNP was(220.4±9.9)nm,and the particle dispersion index(PDI) was(0.172± 0.015), the average zeta potential was ( 35.6 ± 1.7) mv. It was showed spherical dispersion by transmission electron microscopy. The encapsulation efficiency was up to 96.7% and the drug entrapment content was 481.76 ng/mg. Flow cytometric showed the suitable conditions for SNP-SonoVue preparation was that the ratio of SNP quality(mg) to Sono Vue microbubbles number(a) was20:(2.8×109)to40:(2.8× 109). Fluorescence microscopy showed that shells of SonoVue microbubbles connected with large numbers of SNP labeled with red fluorescent DiI. Drug release experiment showed that the cumulative SDF-1α release amount of SNP and SNP-SonoVue exposed to LIFU respectively were ( 68.61 ± 3.97 )% and ( 63.21 ± 5.68)% in vitro within 7 days, and the difference was not statistically significant ( P ＞ 0.05 ). Cell migration experiments confirmed that the transfer function of BMSCs in Group A, Ggroup B and group C was significantly higher than that in control group ( P ＜ 0.05 ), but there was no significant difference among the Group A, Ggroup B and group C ( P ＞0.05). In vitro development experiment showed that the SNP-SonoVue complex had obviously enhanced development effect. Conclusions SNP-SonoVue complex is successfully prepared. It has obviously enhanced development effect and can lead to migration of BMSCs.
