Herpes simplex virus type-1 (HSV-1) reactivation following Streptococcus pneumoniae infection is well described but most cases are related to oral or cutaneous lesions or in respiratory samples. HSV-1 CNS reactivation after Streptococcus pneumoniae meningitis is a very rare event and may have significant morbidity and mortality. In this case report, we describe a 71-year-old female patient that presented with a history of abdominal pain and confusion/disorientation that had tonic-clonic seizures while in the Emergency Department. The diagnostic work-up confirmed CNS co-infection caused by Streptococcus pneumoniae and HSV-1. Of note, beyond age, the patient had no known risk factors for both entities and recovered fully after antibiotic and antiviral therapy. This case underlines that clinicians must be aware of CNS co-infection despite being a rare diagnosis. This should be suspected particularly in patients who present an unusual clinical course of CNS infection.展开更多

Peripheral blood was used for DNA extraction and polymerase chain reaction amplification. SGK1 gene was sequenced by using Big Dye Terminator v3.1 cycle sequencing Kit(Applied Biosystems, Foster City, CA, USA). The SGK-1 gene and its variants were investigated in CSC patient group and control group.RESULTS: We identified a new polymorphism M32 V in two person in the patient group [Minor allele frequency(MAF) =0.009] on the region of 1-60 amino acids. The rs1057293 was located in the encoder region of the SGK- 1 gene but not associated with CSC(P =0.68). An intrinsic rs1743966 is also not associated(P =0.28).CONCLUSION: The new polymorphism M32 V is located on the region of 1-60 amino acids which is necessary for localization to the mitochondria in CSC patient. This mutation is probably important for the energy metabolism and plays an important role in the cellular response to hyperosmotic stress and other stress stimuli. Both rs1057293 and rs1743966 are not associated with CSC.展开更多

Methods: In this case series, 59 eyes (59 patients) diagnosed with subacute CSC in Shenyang the 4th hospital from January 2014 to December 2015 were treated with 1/3-dose verteporfin PDT and followed up for at least 1 year. The symptoms and the diagnosed history were more than 3 months but shorter than 6 months. The central foveal thickness (CFT), neuroretinal thickness (NRT), height of subfoveal retinal fluid (SRF), and subfoveal choroidal thickness (SCT) were observed at baseline and after treated at 1, 2, 3, 6 and 12 months with EDI-OCT, Best-corrected visual acuity ( BCVA) was also studied at the same time. Results: After 1, 2, 3 and 6 months of 1/3-dose verteporfin PDT treatment, the BCVA improved significantly (P 0.05). The height of SRF changed significantly. There was no retinal pigment epithelium atrophy and choroidal neovascularization (CNV) in all cases after more than 12 months follow-up. Conclusion: Treatment of 1/3 dose verteporfin PDT could safely and effectively reduce expansion of choroidal vessel and choroidal choriocapillary, promoting absorbance of subretinal fluid for subacute CSC. 1/3-dose verteporfin PDT may be an alternative method to treat the subacute CSC.展开更多

The study found that: farmers' income has always been the focus of attention; agricultural production has shifted from total demand to green ecology; urban and rural resource elements are not well-organized, resulting in internal contradictions. The implementation of the rural revitalization strategy is an important measure to fundamentally solve the rural development problems in the new era.展开更多

文摘BACKGROUND Cognitive dysfunction is the main manifestation of central neuropathy.Although cognitive impairments tend to be overlooked in patients with diabetes mellitus(DM),there is a growing body of evidence linking DM to cognitive dysfunction.Hyperglycemia is closely related to neurological abnormalities,while often disregarded in clinical practice.Changes in cerebral neurotransmitter levels are associated with a variety of neurological abnormalities and may be closely related to blood glucose control in patients with type 2 DM(T2DM).AIM To evaluate the concentrations of cerebral neurotransmitters in T2DM patients exhibiting different hemoglobin A1c(HbA1c)levels.METHODS A total of 130 T2DM patients were enrolled at the Department of Endocrinology of Shanghai East Hospital.The participants were divided into four groups according to their HbA1c levels using the interquartile method,namely Q1(<7.875%),Q2(7.875%-9.050%),Q3(9.050%-11.200%)and Q4(≥11.200%).Clinical data were collected and measured,including age,height,weight,neck/waist/hip circumferences,blood pressure,comorbidities,duration of DM,and biochemical indicators.Meanwhile,neurotransmitters in the left hippocampus and left brainstem area were detected by proton magnetic resonance spectroscopy.RESULTS The HbA1c level was significantly associated with urinary microalbumin(mALB),triglyceride,low-density lipoprotein cholesterol(LDL-C),homeostasis model assessment of insulin resistance(HOMA-IR),and beta cell function(HOMA-β),N-acetylaspartate/creatine(NAA/Cr),and NAA/choline(NAA/Cho).Spearman correlation analysis showed that mALB,LDL-C,HOMA-IR and NAA/Cr in the left brainstem area were positively correlated with the level of HbA1c(P<0.05),whereas HOMA-βwas negatively correlated with the HbA1c level(P<0.05).Ordered multiple logistic regression analysis showed that NAA/Cho[Odds ratio(OR):1.608,95%confidence interval(95%CI):1.004-2.578,P<0.05],LDL-C(OR:1.627,95%CI:1.119-2.370,P<0.05),and HOMA-IR(OR:1.107,95%CI:1.031-1.188,P<0.01)were independent predictors of poor glycemic control.CONCLUSION The cerebral neurotransmitter concentrations in the left brainstem area in patients with T2DM are closely related to glycemic control,which may be the basis for the changes in cognitive function in diabetic patients.

文摘Transforming growth factor-beta 1(TGF-β1)has been extensively studied for its pleiotropic effects on central nervous system diseases.The neuroprotective or neurotoxic effects of TGF-β1 in specific brain areas may depend on the pathological process and cell types involved.Voltage-gated sodium channels(VGSCs)are essential ion channels for the generation of action potentials in neurons,and are involved in various neuroexcitation-related diseases.However,the effects of TGF-β1 on the functional properties of VGSCs and firing properties in cortical neurons remain unclear.In this study,we investigated the effects of TGF-β1 on VGSC function and firing properties in primary cortical neurons from mice.We found that TGF-β1 increased VGSC current density in a dose-and time-dependent manner,which was attributable to the upregulation of Nav1.3 expression.Increased VGSC current density and Nav1.3 expression were significantly abolished by preincubation with inhibitors of mitogen-activated protein kinase kinase(PD98059),p38 mitogen-activated protein kinase(SB203580),and Jun NH2-terminal kinase 1/2 inhibitor(SP600125).Interestingly,TGF-β1 significantly increased the firing threshold of action potentials but did not change their firing rate in cortical neurons.These findings suggest that TGF-β1 can increase Nav1.3 expression through activation of the ERK1/2-JNK-MAPK pathway,which leads to a decrease in the firing threshold of action potentials in cortical neurons under pathological conditions.Thus,this contributes to the occurrence and progression of neuroexcitatory-related diseases of the central nervous system.
文摘Purpose: To study the safety and efficacy of 1/3-dose verteporfin photodynamic therapy (PDT) for subacute central serous chorioretinopathy (CSC). Methods: In this case series, 59 eyes (59 patients) diagnosed with subacute CSC in Shenyang the 4th hospital from January 2014 to December 2015 were treated with 1/3-dose verteporfin PDT and followed up for at least 1 year. The symptoms and the diagnosed history were more than 3 months but shorter than 6 months. The central foveal thickness (CFT), neuroretinal thickness (NRT), height of subfoveal retinal fluid (SRF), and subfoveal choroidal thickness (SCT) were observed at baseline and after treated at 1, 2, 3, 6 and 12 months with EDI-OCT, Best-corrected visual acuity ( BCVA) was also studied at the same time. Results: After 1, 2, 3 and 6 months of 1/3-dose verteporfin PDT treatment, the BCVA improved significantly (P 0.05). The height of SRF changed significantly. There was no retinal pigment epithelium atrophy and choroidal neovascularization (CNV) in all cases after more than 12 months follow-up. Conclusion: Treatment of 1/3 dose verteporfin PDT could safely and effectively reduce expansion of choroidal vessel and choroidal choriocapillary, promoting absorbance of subretinal fluid for subacute CSC. 1/3-dose verteporfin PDT may be an alternative method to treat the subacute CSC.
