Journal of Apoplexy and Nervous Diseases 2022;39(5):419-424
To investigate the expression of vitamin D receptor (VDR) in different central nervous system regions and neurological function scores of experimental autoimmune encephalomyelitis (EAE) mice and healthy control mice. Methods EAE mice were divided into 0 score group,high score group and low score group according to Weaver’s 15 score neurological function score. The myelin sheath structure of each group was observed by transmission electron microscope. And Western Blot was used to detect the expression of VDR protein in cortex,white matter,cerebellum,brain stem and spinal cord of EAE high score group mice and healthy control group mice. According to the results,the expression of VDR protein in spinal cord was further compared between healthy control group and EAE groups. Results The myelin sheath structure of 0 score group,high score group and low score group mice was observed under transmission electron microscope. Compared with the healthy control group,the myelin sheath ring structure of 0 group and low group existed,and the myelin sheath ring structure of high score group disappeared. In cortex,white matter,cerebellum,brainstem and spinal cord,the expression of VDR protein in EAE group was lower than that in healthy control group (P cortex=0.893;P white matter=0.767;Pcerebellum=0.225). The expression of VDR protein in brainstem and spinal cord was significantly lower than that in healthy control group (P=0.046;P=0.009). In spinal cord,the expression of VDR protein in 0 score group,high score group and low score group was lower than that in healthy control group (P=0.005,P=0.009,P<0.0001);high score group was lower than 0 score group (P=0.716),low score group was further lower than 0 score group (P= 0.003),while low score group and high score group also showed a downward trend (P=0.013). Conclusions The expression of VDR protein in different central nervous system regions of EAE mice was different,and the expression of VDR protein was different in different nerve function score groups.

To investigate the executive function impairment in CBS patients and its relationship with the microstructural integrity of white matter fiber tracts. MethodsEleven CBS patients and 17 cognitively normal subjects who visited our hospital from November 2018 to November 2019 were evaluated for executive function,including forward digit span,reverse digit span,correct line of TMT-A line,and correct line of TMT-B line. Diffusion tensor imaging(DTI)scans were performed in the CBS control group to compare the fractional anisotropy(FA)value,mean diffusivity(MD)value,axial diffusivity(AD)and radial diffusivity(RD)values of the fiber bundles with changed microstructure with executive function scores. ResultsExcept for CBS digit span forward score(P=0.446),reverse digit span(P<0.001),correct line of TMT-A line(P<0.001)and correct line of TMT-B line(P<0.001),the differences were statistically significant. Compared with the HC group,the FA values of the left corticospinal tract,anterior thalamic radiation,cingulate fasciculus,superior longitudinal fasciculus,inferior longitudinal fasciculus,and corpus callosum were reduced in the CBS group compared with the HC group,and the difference was not statistically significant(P>0.05). The MD values,AD values,and RD values of the left corticospinal tract,anterior thalamic radiation,cingulate tract,superior longitudinal tract,inferior longitudinal tract,and corpus callosum were increased in the CBS group(lesion side)and the HC group compared with the HC group,and the differences were statistically significant(P<0.05). The reverse digit span was negatively correlated with the RD value of the superior longitudinal fasciculus of the lesion(r=-0.741,P=0.036),and the reverse digit span was negatively correlated with the RD value of the superior longitudinal fasciculus of the lesion. ConclusionPatients with CBS have executive dysfunction and changes in the integrity of white matter fiber tracts;executive dysfunction in patients with CBS is related to changes in the integrity of white matter fiber tracts in addition to frontotemporal atrophy;abnormal structural connectivity of white matter fibers may be one of the causes of executive dysfunction in patients with CBS.

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.

AIMNineteen compounds related to salicylic acid were evaluated for their in vitro activity of inhibiting beta-lactamase isolated from a resistant strain of Pseudomonas aeruginosa, and their structure-activity relationships were examined.
METHODSNitrocefin method was used.
RESULTSThe 50% inhibitory concentration (IC50) of salicylic acid inhibiting beta-lactamase was 22 mmol x L(-1); four analogs had IC50 lower than that of salicylic acid; fifteen analogs had IC50 higher than that of salicylic acid.
CONCLUSIONExamination of the structure-activity relationships of the compounds revealed that carboxyl group and adjoining hydroxyl group were active group, and replacement of adjoining hydroxyl by carboxyl increased activity nearly 4-fold. Moreover, addition of a sulfonic group at C-5 and nitro group at C-3, 5 of benzenoic ring of salicylic acid resulted in a 2-fold to 3-fold increase in activity, addition of a amino group at C-5 of benzenoic ring of salicylic acid decreased activity, add addition of -Cl or -F at C-2,4 position of benzenoic ring of benzoic acid did not show activity.

OBJECTIVE: To study the improvement and anti-inflammation mechanism of Shenfu injection on lung tissue of endotoxin shock model rats. METHODS: Totally 48 rats were randomized into control group,model group,dexamethasone group (positive control,1 mg/kg) and Shenfu injection low-dose,medium-dose and high-dose groups (5,10,15 mL/kg),with 8 rats in each group. Except for normal group, other groups were given intraperitoneal injection of lipopolysaccharide (LPS) to induce endotoxin shock model. After modeling, each group was given relevant medicine once intraperitoneally. 24 h after medication, HE staining was used to observe pathological changes of lung tissue in rats and pathological scoring was conducted. RT-PCR was used to determine mRNA levels of P65 and P50 proteins related to NF-κB signaling pathway. Western blot assay was used to determine the expression levels of P65 and P50 proteins in lung tissue, and the expression levels of P65 protein in nucleus and cytoplasm of lung tissue were also determined. The level of TNF-α in plasma in rats were determined by ELISA. RESULTS: Compared with control group, alveolar septum became thicker, obvious vascular engorgement was found, and a large number of neutrophils infiltrated the interstitium in model group. Histopathological score, mRNA and protein expression levels of P65 and P50 in lung tissues were increased significantly (P<0.01 or P<0.001); the protein expression of levels P65 in nucleus and cytoplasm and level of TNF-α in plasma were increased significantly (P<0.001). Compared with model group, alveolar structure of rats in dexamethasone group and Shenfu injection medium-dose and high-dose groups was complete, no obvious bleeding was observed, and the degree of inflammatory cell infiltration was improved significantly. Histopathological score, mRNA and protein expression levels of P65 and P50 in lung tissue and level of TNF-α in plasma were decreased significantly (P<0.05 or P<0.01 or P<0.001). The protein expression level of P65 in nucleus and cytoplasm of lung tissue were decreased significantly in dexamethasone group and Shenfu injection low-dose and medium-dose groups were decreased significantly (P<0.05 or P<0.01 or P<0.001). CONCLUSIONS: Shenfu injection can decrease mRNA and protein expression levels of P65 and P50 in lung tissue, level of TNF-α in plasma, and protect lung tissue of endotoxin shock rats.

To determine the types and proportion of common hemoglobin variants in Tianjin and surrounding areas, to analyze the recognition ability and the effects of hemoglobin variants on experimental results in two commonly used glycated hemoglobin systems, so as to provide data support for the consistency of HbA1c detection in Tianjin City. A case-control study was used for retrospective analysis,156 specimens with abnormal electrophoretic peaks in the detection of glycated hemoglobin were collected from more than 50 000 specimens of patients in Chu Hsien-I Memorial Hospital of Tianjin Medical University between June 2020 and December 2020. Determined their hemoglobin mutation sites by DNA sequencing, and compared the values of hemoglobin variants on glycated hemoglobin detection values by high performance liquid chromatography and capillary electrophoresis. SPSS 23 was used to calculate the blood routine results of the variant specimens, and compared with the normal reference interval. The results showed that DNA sequencing identified 21 hemoglobin variants, of which 11 were α strand variants and 10 were β strand variants. In addition, an unreported hemoglobin variant was identified, Hb Headington (HBB: c.217A>C). The HbA1c of 11 variants including Hb G-Honolulu, Hb Queens, Hb Q-Thailand, Hb J-Broussais, Hb O-Indonesia, Hb G-Coushatta, Hb G-Taipei, Hb E, Hb Headington, Hb New York and Hb D-Los Angeles were shifted by more than 7% when measured by high-performance liquid chromatography. Patients with the Hb Q-Thailand and Hb E cause reduced MCV and MCH. In conclusion, an unreported hemoglobin variant was found from Tianjin and neighboring areas. Patients with the Hb Q-Thailand and Hb E cause reduced MCV and MCH. 11 of these hemoglobin variants interfered with the detection of glycated hemoglobin using high-performance liquid chromatography, resulting in inaccurate results.
