Efficacy and safety comparison of lacosamide and carbamazepine in the treatment of adult patients with newly diagnosed epilepsy / 中国药房

OBJECTIVE To compare the efficacy and safety of lacosamide （LCM） and carbamazepine （CAR） as monotherapy in the treatment of adult patients with newly diagnosed epilepsy. METHODS By methods of retrospective analysis， 84 adult patients with newly diagnosed epilepsy， were admitted to the Department of Neurology， Huaihe Hospital of Henan University during Sept. 2020-Jun. 2022， were divided into the control group （40 cases， receiving CAR treatment） and the observation group （44 cases， receiving LCM treatment） according to different medication regimens. Total response rate， epilepsy seizure frequency， blood lipid levels， and the occurrence of adverse events （AEs） of patients were compared between the 2 groups. RESULTS In the first month after treatment， there was no statistically significant difference in the total response rate between the observation group （63.64%） and the control group （55.00%， P＞0.05）； the frequency of epilepsy seizure in both groups was significantly reduced compared to before treatment （P＜0.05）， but there was no statistically significant difference between 2 groups （P＞0.05）. In the third month after treatment， the total response rate of the observation group （90.91%） was significantly higher than control group （67.50%， P＜0.05）； the frequencies of epilepsy seizure in both groups were significantly reduced compared to before treatment， and the observation group was significantly lower than the control group （P＜0.05）. In the third month after treatment， the levels of total cholesterol （TC）， triglyceride （TG） and low-density lipoprotein cholestrol （LDL-C） in the control group and the level of LDL-C in the observation group were significantly higher than before treatment， and the levels of TC， TG and LDL-C in the observation group were significantly lower than those in the control group （P＜0.05）. There was no statistically significant difference in the incidence of AEs between the observation group （15.91%） and the control group （17.50%， P＞0.05）. CONCLUSIONS Both LCM and CAR have certain effects in the treatment of newly diagnosed epilepsy in adults， which can reduce the frequency of epilepsy seizure in patients and have comparable safety. Meanwhile， LCM has better long-term efficacy than CAR in treating newly diagnosed epilepsy in adults， and its impact on the patient’s blood lipid is smaller than CAR.

A linear DNA vaccine candidate encoding the SARS-CoV-2 Receptor Binding Domain elicits protective immunity in domestic cats

Since its first detection in China in late 2019, SARS-CoV-2, the etiologic agent of COVID-19 pandemic, has infected a wide range of animal species, especially mammals, all over the world. Indeed, as reported by the American Veterinary Medical Association, besides human-to-human transmission, human-to-animal transmission has been observed in some wild animals and pets, especially in cats. With animal models as an invaluable tool in the study of infectious diseases combined with the fact that the intermediate animal source of SARS-CoV-2 is still unknown, researchers have demonstrated that cats are permissive to COVID-19 and are susceptible to airborne infections. Given the high transmissibility potential of SARS-CoV-2 to different host species and the close contact between humans and animals, it is crucial to find mechanisms to prevent the transmission chain and reduce the risk of spillover to susceptible species. Here, we show results from a randomized Phase I/II clinical study conducted in domestic cats to assess safety and immunogenicity of a linear DNA ("linDNA") vaccine encoding the RBD domain of SARS-CoV-2. No significant adverse events occurred and both RBD-specific binding/neutralizing antibodies and T cells were detected. These findings demonstrate the safety and immunogenicity of a genetic vaccine against COVID-19 administered to cats and strongly support the development of vaccines for preventing viral spread in susceptible species, especially those in close contact with humans.

A case report of intracranial infection caused by Aggregatibacter aphrophilus / 中华神经科杂志

Aggregatibacter aphrophilus is a member of the normal flora of the human oral cavity and pharynx, a Gram-negative fastidous bacteria, belonging to agglomerates, which is a normal mixed oropharyngeal flora in humans, most commonly colonized on the surface of oral mucosa. This bacterial infection is rare in clinical practice, and it is difficult to culture and identify the bacteria, which is easy to be missed. A patient with intracranial infection was admitted to Huaihe Hospital, who showed fever and headache as the main clinical manifestations, and Aggregatibacter aphrophilus was detected by the metagenomic next-generation sequencing of cerebrospinal fluid. The patient′s symptoms were significantly improved after anti-infection treatment.

From vulnerable plaque to blood healthy therapy.

Cardiovascular atherosclerotic disease is the leading cause of death in China and in Western nations. People with plaque or stenosis in the coronary artery or the carotid artery are the most susceptible population to suffer from acute events. Current investigations showed that plaque with the characteristics of intra-plaque hemorrhage or a thin cap with a large lipid core was causally associated with vulnerable plaque and plaque rupture. Of the many plaque ruptures occurring in patients with atherosclerotic disease, very few will trigger symptomatic events, rendering it exceedingly difficult to predict adverse outcomes. The assumption that identifying lesions prone to rupture will prevent acute coronary events was unrealistic. Factors in blood, especially those risk factors associated with thrombosis, play an important role as a bridge between plaque rupture and subsequent clinical events. Since there is little management to efficiently decrease the frequency of plaque rupture or erosion, blood healthy therapy, as a therapeutic apheresis to decrease the blood hypercoagulability to modulate the blood to be thrombosis resisting, should be considered as a potential therapeutic approach to reducing the incidence of acute coronary syndrome and stroke.

Clinical outcome of allogeneic hematopoietic stem cell transplantation with FLAG sequential busulfan/cyclophosphamide conditioning regimen for refractory/relapsed acute myeloid leukemia / 中华内科杂志

Objective@#To investigate the therapeutic effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with FLAG sequential busulfan/cyclophosphamide(Bu/Cy) conditioning regimen for refractory/relapsed acute myeloid leukemia.@*Methods@#From February 2012 to June 2017, 21 patients with refractory/relapsed acute myeloid leukemia underwent allo-HSCT with FLAG sequential Bu/Cy conditioning regimen. Transplantation-related complications and clinical outcome were retrospectively analyzed.@*Results@#After conditioning, no hepatic veno-occlusive disease (VOD) and grade Ⅲ hemorrhagic cystitis occurred. 76.2% (16/21) patients had fever with 4 septicemia. One patient died of septic shock before engraftment. Twenty patients achieved neutrophil engraftment with a median time of 13 days (range, 10 to 21 days). Seventeen patients achieved platelet engraftment with a median time of 18 days (range, 9 to 25 days). The cumulative incidence of acute graft-versus-host disease (aGVHD) was 39.5%, and 3 patients developed grade Ⅲ-Ⅳ aGVHD. Of 19 patients who survived more than 100 days after transplantation, 4 had local chronic graft-versus-host disease (cGVHD). Of 21 patients, the median survival time was 15 months (range, 0.5 to 67 months) post-transplantation. Transplantation-related mortality rate was 28.7%. Leukemia relapse occurred in 4 patients with a median time of 4 months (range, 3 to 8 months) after transplantation. The cumulative relapse rate at 1 year was 21.4%. The 1-year and 3-year overall survival (OS) rates were 60.7% and 54.9% respectively. Log-rank analysis revealed that bone marrow blasts ≥ 20% or extramedullary leukemia before transplantation, poor platelet engraftment and grade Ⅲ-Ⅳ aGVHD were significantly related to shortened OS (P<0.05).@*Conclusions@#Allo-HSCT with FLAG sequential Bu/Cy conditioning regimen in patients with refractory/relapsed myeloid leukemia has acceptable transplantation-related risk and relapse rate. The 1-year and 3-year OS rates are comparable with those in remission patients.

Determining Osteogenic Differentiation Efficacy of Pluripotent Stem Cells by Telomerase Activity

BACKGROUND: Bone tissue engineering based on pluripotent stem cells (PSCs) is a new approach to deal with bone defects. Protocols have been developed to generate osteoblasts from PSCs. However, the low efficiency of this process is still an important issue that needs to be resolved. Many studies have aimed to improve efficiency, but developing accurate methods to determine efficacy is also critical. Studies using pluripotency to estimate efficacy are rare. Telomerase is highly associated with pluripotency. METHODS: We have described a quantitative method to measure telomerase activity, telomeric repeat elongation assay based on quartz crystal microbalance (QCM). To investigate whether this method could be used to determine the efficiency of in vitro osteogenic differentiation based on pluripotency, we measured the pluripotency pattern of cultures through stemness gene expression, proliferation ability and telomerase activity, measured by QCM. RESULTS: We showed that the pluripotency pattern determined by QCM was similar to the patterns of proliferation ability and gene expression, which showed a slight upregulation at the late stages, within the context of the general downregulation tendency during differentiation. Additionally, a comprehensive gene expression pattern covering nearly every stage of differentiation was identified. CONCLUSION: Therefore, this assay may be powerful tools for determining the efficiency of differentiation systems based on pluripotency. In this study, we not only introduce a new method for determining efficiency based on pluripotency, but also provide more information about the characteristics of osteogenic differentiation which help facilitate future development of more efficient protocols.

Quercetin protects human brain microvascular endothelial cells from fibrillar β-amyloid1-40-induced toxicity

Amyloid beta-peptides (Aβ) are known to undergo active transport across the blood-brain barrier, and cerebral amyloid angiopathy has been shown to be a prominent feature in the majority of Alzheimer׳s disease. Quercetin is a natural flavonoid molecule and has been demonstrated to have potent neuroprotective effects, but its protective effect on endothelial cells under Aβ-damaged condition is unclear. In the present study, the protective effects of quercetin on brain microvascular endothelial cells injured by fibrillar Aβ 1-40 (fAβ 1-40) were observed. The results show that fAβ 1-40-induced cytotoxicity in human brain microvascular endothelial cells (hBMECs) can be relieved by quercetin treatment. Quercetin increases cell viability, reduces the release of lactate dehydrogenase, and relieves nuclear condensation. Quercetin also alleviates intracellular reactive oxygen species generation and increases superoxide dismutase activity. Moreover, it strengthens the barrier integrity through the preservation of the transendothelial electrical resistance value, the relief of aggravated permeability, and the increase of characteristic enzyme levels after being exposed to fAβ 1-40. In conclusion, quercetin protects hBMECs from fAβ 1-40-induced toxicity.

Changes of cholinergic neurons in the hippocampus of vascular dementia rats after neural stem cell transplantation / 中国组织工程研究

each group were sacrificed, respectively. Distributions of BrdU positive cels and ChAT positive cels were detected by S-P immunohistochemical method. The learning and memory abilities of rats were detected by Morris water maze system. RESULTS AND CONCLUSION:BrdU positive cels were mainly distributed in the cortex and hippocampus, especialy around the blood vessels, and there was the presence of focal aggregation. A smal amount of BrdU positive cels were observed in the basal ganglia and thalamus as wel as in the ependyma. BrdU positive cels were counted at different time after operation. The number of BrdU positive cels decreased with time, and only a smal number of BrdU positive cels were observed at 60 days after transplantation. The number of ChAT positive cels at different time after transplantation was ranked as folows: neural stem cel transplantation group > model group > sham operated group (P < 0.05). Compared with the model group, the time for searching the platform was significantly lower in the neural stem transplantation group and sham operated group, but the number of crossing the platform was significantly higher in the neural stem cel transplantation group and sham operated group (P < 0.05). The results show that neural stem cels could be transplanted into the rats with vascular dementia, and the cels could survive and migrate in the brain of rats and significantly improve the learning and memory ability. This mechanism may be related to the differentiation and growth of cholinergic neurons in the hippocampus.

The Inhibitory Effect of Baixuan Xiatare Tablet on Model Mouse with Allergic Contact Dermatitis / 中国药房

OBJECTIVE:To investigate the inhibitory effect of Baixuan xiatare tablet on the model mouse with allergic contact dermatitis (ACD). METHODS:60 BALB/c mice were equally randomized into normal control (isometric solvent) group,model (isometric solvent)group,ebastine(positive control,0.003 g/kg)group and the groups of high,middle and low doses of Baixuan xiatare tablet(2.0,1.0 and 0.5 g/kg). The mice were given drugs,ig,once daily for 14 consecutive days. 0.5% 2,4-dinitrofluoro-benzene(DNFB)acetone olive oil solution was applied,for sensitization,on the prepared mouse’s skins one and two days before administration,and 0.2% DNFB acetone olive oil solution on their left ears 16 days thereafter to establish mouse models of ACD. At 48 h after successful establishment of the models,the thickness of the mouse’s left ear margin was measured and the difference value and swelling degree were calculated;flow cytometer was used to determine the levels of T lymphocyte subsets CD4+ and CD8+ in mouse blood and calculate the ratio of CD4+ to CD8+;the levels of interleukin 4(IL-4)and IL-6 in mouse serum were de-termined. RESULTS:Compared with normal control group,those in the model group had higher difference value of ear margin and swelling degree,lower level of CD4+ in blood and ratio of CD4+ to CD8+,and higher content of IL-6 in serum. There was statisti-cally difference (P<0.01). Compared with model group,those in the groups of high,middle and low doses of Baixuan xiatare tablet had lower degree of left ear swelling and higher level of CD4+ in blood;those in the groups of high and middle doses thereof had lower difference value of left ear margin and level of IL-6 in serum;and those in the group of high dose thereof had higher lev-el of CD8+ in blood. There was statistically significance(P<0.01 or P<0.05). CONCLUSIONS:Baixuan xiatare tablet has inhibi-tory effect to some degree on the mouse model with ACD by a mechanism which may be related to the balance of subsets CD4+and CD8+in blood and the reduction of IL-6 in serum.

<p><b>OBJECTIVE</b>To study on the new preparation technology of Hugan Buzure granule and to compare protective effect on liver injury in rats by different extraction processes.</p><p><b>METHOD</b>Volatile oil extraction technology, inclusion condition and ethanol extraction condition were selected by orthogonal experiments. The experiment models of liver injury were induced by carbon tetrachloride, bacillus calmette-guerin (BCG) and plus lipolysaccharides (LPS) in rats, respectively. ALT, AST in serum, and MDA, SOD in liver were measured and the rats were killed to calculate the liver coefficient to evaluate the protective effect of Hugan Buzure granule on experimental injury in rats.</p><p><b>RESULT</b>The optimum conditions of volatile oil extraction were 1:12 of solid-liquid ratio, 2 h of soaking time, and 8 h of extracting time. The optimal beta-cyclodextrin inclusion complex condition was as follows: the volatile oils formed complex with the beta-CD in a ratio of 1: 6 and stirring for 1 h at 40 degrees C. The optimum ethanol extraction was as follows: refluxing and extracting 3 times with 10-fold 50% ethanol, 2 h for each time. Compared with the model group, the new technology extraction of Hugan Buzure granule could obviously inhibite the elevation of serum ALT (P < 0.01), AST (P < 0.05) of liver injury induced by BCG + LPS, and elevate the contents of SOD, and obviously inhibite the elevation of serum AST (P < 0.01) of liver injury induced by carbon tetrachloride.</p><p><b>CONCLUSION</b>The new preparation technology was feasible. The new extraction could protect the liver injury in rats, which was better than extraction of current preparation technology.</p>

Change of the concentration of monoamine neurotransmitters in serum in patients with post-stroke depression / 中国康复理论与实践

@#ObjectiveTo explore the change of the concentration of monoamine neurotransmitters in serum in patients with post stroke depression(PSD).Methods85 patients with acute stroke were screened by Center for Epidemiological Survey,Depression Scale(CES-D) and assessed by Hamilton Depression Scale(HAMD).A clinical diagnostic of depression was made based on Diagnostic and Statistical Mannal of Mental Disorders,edition 4(DSM-Ⅳ).There were 34 patients who involved with depression(PSD group), the others(51 cases) not(no depression group).Other 20 normal persons were chosen as a control(control group). In all patients and control subjects, the concentrations of monoamine neurotransmitters in serum was measured.ResultsThe concentration of monoamine neurotransmitters in serum was significantly lower in patients with post stroke depression.ConclusionsPost stroke depression is related to decrease of concentrations of monoamine neurotransmitters in serum.
