Objective To investigate the therapeutic effectiveness of Xiyanping aerosol inhalation for pulmonary infection in patients with acute stroke. Methods Sixty-three patients with pulmonary infection after acute stroke were enrolled and randomly allocated to either a treatment group or a control group. The control group was treated with anti-infective and apophlegmatisant on the basis of standardized stroke treatment, the treatment group was treated with Xiyanping aerosol inhalation on the basis of the treatment in the control group. All patients were treated for 14 days. The resolution times of symptom and signs, and the changes of inflammatory parameters were compared. Results The total effective rate in the treatment group was significantly higher than that in the control group (93.75%vs. 74.19%;χ2=4.510, P=0.034). The resolution times of symptom and signs, such as cough and excessive phlegm (5.94 ± 1.25 d vs. 6.73 ± 1.48 d;t=2.292, P=0.025),fever (2.72 ± 0.11 d vs. 3.25 ± 0.18 d;t=12.046, P<0.01), pulmonary rale (5.22 ± 1.15 d vs. 7.21 ± 1.21 d;t=6.693, P<0.01), and dyspnea (1.17 ± 0.49 d vs. 2.82 ± 0.61 d;t=11.855, P<0.01) in the treatment group were significantly shorter than those in the control group. White blood cell count (2.55 ± 1.02 ×109/L vs. 3.91 ± 1.25 ×109/L;t=4.738, P<0.01), granulocyte proportion (4.92% ± 1.32% vs. 6.25% ± 1.16%; t=4.738, P<0.01) and lymphocyte proportion (58.62%± 6.15%vs. 65.94%± 6.17%;t=4.716, P<0.01) in the treatment group were significantly lower than those in the control group. Conclusions Xiyanping aerosol inhalation can shorten the resolution times of symptom and signs, and improve the therapeutic effectiveness in patients with pulmonary infection after acute stroke.

Objective:To explore the effect of nontypeable Haemophilus influenzaen(NTHi)strain ATCC49247on pri-mary rabbit tracheal epithelial(TE)cells.Methods:TE cells were isolated with low temperature protease digestion and cul-tured on collagen gel-coated membranes at an air-liquid interface in serum-free medium.Under these conditions,TE cells were proliferated and differentiated into a pseudostratified mucociliary epithelium,which were infected by NTHi.Morphologic changes of the cells were examined by scanning electron microscopy(SEM)and transmission electron microscopy(TEM)after 24h.Results:SEM showed that bacteria adhered to non-ciliated cells;death or apoptosis occurred in90%of TE cells and cil-iaries were broken.TEM showed NTHi adhered to the cell surface on which there were many microvillus.Lamellipodia and microvilli surrounded bacteria within vacuoles of airway cells.Conclusion:NTHi can attach to non-ciliated cells,the latter de-vours the bacteria by lamellipodia and microvilli.NTHi is toxic to TE cells,resulting in the death or apoptosis of TE cells.

Objective To observe the effects of Chinese herbal compounds (alkaloid of Coptidis Rhizoma 40%, total saponin of panax notoginseng 35%, and polysaccharide of Ophiopogonis Radix 25%) on levels of blood glucose, fructosamine, and insulin of diabetic rats, and explore mechanism of action.Methods Ten rats were randomly chosen as blank control group, and other rats were used to establish diabetic rat models by STZ intraperitoneal injection. Successfully molding rats were randomly divided into Chinese herbal compounds high, medium, low dose groups, metformin group, and model group, 10 rats in each group. Each rat received gavage for continuous 4 weeks. Then rat blood was collected by cutting head and taking caudal vein. FBG was detected by glucose oxidase method;insulin level was detected by radio-immunity double antibody method;fructosamine content was detected by fructosamine method.Results Compared with the blank control group, model group the levels of FBG, froctosamine content increased, while fasting insulin level were lower after 4 weeks'medication. Compared with the model group, the levels of FBG, froctosamine content in Chinese herbal compounds high and medium dose groups and metformin group were lower, while fasting insulin level increased after 4 weeks'medication (P<0.05).Conclusion TCM herbal compounds can increased the basic insulin level by decreasing the contents of FBG and fructosamine.

Objective:To identify the hub differentially expressed genes(DEGs)of glomerular pathological changes and potential pathways in molecular process of type 2 diabetic nephropathy(DN)based on bioinformatics technology.Methods:The differentially expressed genes of Gene Expression Omnibus(GEO)dataset GSE96804 in DN and normal kidney tissues were analyzed by R 3.6.2 software. DEGs were further assessed by Gene Ontology(GO)function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signal pathway analysis. Subsequently, the hub genes and their associated pathways were analyzed using String 11.0 and Cytoscape 3.7.2 software.Results:A total of 168 DEGs were obtained in the dataset. Among them, seven hub genes were identified, including ALB, FN1, EGF, PTGS2, PLG, KDR, and LOX. Three hub genes, ALB, EGF, PLG, exerted a direct action on glomerulus. GO enrichment analysis of DEGs was mainly manifested in extracellular matrix organization, extracellular structure organization, platelet degranulation and other biological processes, extracellular matrix, secretory granule lumen, platelet alpha granule and other cell components, chaperone binding, copper ion binding, antioxidant activity, and other molecular functions. DEGs mainly regulated metabolic process, which was related to fatty acid degradation signal pathway, exogenous substance metabolism related to CYP enzyme and drug metabolism signal pathway.Conclusion:A bioinformatics analysis of DN from the perspective of glomerulopathy is helpful to understand the potential molecular mechanism of DN and provide reference for further validation.

Objective To get a knowledge of the current status of organ donation and utilization after citizen's death in Wuxi District, and thereby provide ideas and basis for further development of organ donation work in local areas. Methods Clinical data from 151 organ donors, included 37 successful donors and 114 potential donors, were retrospectively analyzed. The reasons for donation failure of potential donors were analyzed. The general information for successful donors was collected. And the information on organ donation and organ utilization in successful donors were analyzed. Results Among the 151 organ donors, 37 were successful donors, with the conversion rate reaching 24.5%. For the 114 donors with failed organ donation, the reasons for failure included family disagreement, failure to meet donation status criteria, insufficient evaluation time, and unresolved work injury disputes. The categories for organ donation included 34 cases of donation after brain death followed by cardiac death (DBCD), 3 cases of donation after brain death (DBD), and no case of donation after cardiac death (DCD). The reasons for death of donors includes 19 cases of craniocerebral trauma, 14 cases of stroke and 4 cases of others. Among the 37 cases of successful donors, the majority were floating population. A total of 154 major organs and tissues were donated, of which 124 were major organs. The number of major organs and tissues donated per citizen was (4.2± 1.6) and the number of major organs donated per citizen was (3.4± 1.1). The utilization rate of the 154 donated organs reached 96.7% (149/154), with Nanjing, Wuxi, Suzhou and Changzhou ranking the top 4 of organ distribution. Conclusions The rate for successful organ donation and conversion after citizen's death is low in Wuxi District. The organ donation work networks in local areas should be established. And organ donation promotion efforts and skills training for coordinators should be developed.

OBJECTIVE: To explore the clinical characteristics and genetic basis for a pair of twins affected with hyaline fibromatosis syndrome (HFS). METHODS: Clinical data of the twins were retrospectively analyzed. High-throughput sequencing was carried out to detect potential pathogenic variants. CLUSTALX was employed to analyze cross-species conservation of the mutant amino acids. Impact of the mutations was predicted by using software including PolyPhen-2 and Mutation taster. RESULTS: The pair of twins have featured growth and intelligence retardation, and were found to carry compound heterozygous variants of the ANTXR2 gene including c.1214G>A and c.1074delT, among which c.1214G>A was unreported previously. Both variants were predicted to be pathogenic. In addition to growth and mental delay, the pair of twins also featured hyperplasia of the gum and soft tissue-like masses of the auricle. The younger brother had rupture of the auricle mass during follow-up. CONCLUSION The patients' condition can probably be attributed to the compound heterozygous variants of the ANTXR2 gene. Above finding has facilitated molecular diagnosis of the patients.

Objective: To determine the changed expression levels, biological roles and underlying mechanism of LncSox4 in non-small cell lung cancer (NSCLC), providing novel biomarkers for NSCLC diagnosis and therapy. Methods: QRT-PCR was used to detect the expression of LncSox4 in the tumor tissues of NSCLC patients. Colony formation, cell growth curve, Transwell migration and invasion assays were used to determine the effects of LncSox4 knockdown on A549 cell function, respectively. Flow cytometry was used to determine the effects of LncSox4 on the progression of A549 cell cycle. QRT-PCR and western blot were used to explore the expressions of genes and proteins in epithelial-mesenchymal transition (EMT). Results: The expression of LncSox4 was upregulated significantly in carcinoma tissues of NSCLC compared to the para-carcinoma tissues (t=7.109，P＜0.01). The growth rate of A549 cells slowed down in LncSox4 knockdown group and the number of formed cell colonies was less than that in control group(P＜0.01). LncSox4 knockdown reduced the migration and invasion abilities of A549 cells (P＜0.01) and induced cell cycle arrest at G1 phase(P＜0.01). LncSox4 knockdown downregulated the protein expressions of Cyclin D1, c-Myc, N-cadherin, and Vimentin, while upregulated the expression of E-cadherin in A549 cells. LncSox4 knockdown also decreased the expressions of EMT-related transcription factors including snail, slug and twist. Conclusion The high expression of LncSox4 in NSCLC may promote malignant progression of NSCLC by enhancing cell proliferation, migration and invasion, suggesting that it should be a promising target for diagnosis and therapy of NSCLC.

Insufficient catalytic efficiency of flavonoid 6-hydroxylases in the fermentative production of scutellarin leads to the formation of at least about 18% of by-products. Here, the catalytic mechanisms of two flavonoid 6-hydroxylases, CYP82D4 and CYP706X, were investigated by molecular dynamics simulations and quantum chemical calculations. Our results show that CYP82D4 and CYP706X have almost identical energy barriers at the rate-determining step and thus similar reaction rates, while the relatively low substrate binding energy of CYP82D4 may facilitate product release, which is directly responsible for its higher catalytic efficiency. Based on the study of substrate entry and release processes, the catalytic efficiency of the L540A mutation of CYP82D4 increased by 1.37-fold, demonstrating the feasibility of theoretical calculations-guided engineering of flavonoid 6-hydroxylase. Overall, this study reveals the catalytic mechanism of flavonoid 6-hydroxylases, which may facilitate the modification and optimization of flavonoid 6-hydroxylases for efficient fermentative production of scutellarin.
