Development of A Patient-reported Outcomes Scale for Post-stroke Aphasia Based on Traditional Chinese Medicine Holism / 中国康复理论与实践

Objective:To develop a patient-reported outcomes (PRO) scale for post-stroke aphasia based on the Traditional Chinese Medicine (TCM) holism. Methods:Referring to the TCM holism, the theoretical model was established following the standard process for the development of the PRO scale. An item pool was established and optimized with case review, patient interview, expert questionnaire survey and consensus conference. The PRO scale was established finally. Results:A pool of post-stroke aphasia items based on the holistic view of TCM was constructed in the physical, psychological and social model. The Expert Comment Form for the PRO Scale for Aphasia after Stroke was formed after sorting out the item pool. After expert surveys and meeting discussion, 40 items were finally selected to form the first version of Patient-reported Outcomes Scale for Post-stroke Aphasia-TCM. Conclusion:The first version of Patient-reported Outcomes Scale for Post-stroke Aphasia-TCM has been developed based on the TCM holism and the concept of PRO, which can be evaluated clinically.

Screening of key genes and pathways of ischemic stroke and prediction of traditional Chinese medicines based on bioinformatics / 中国中药杂志

The aim of this paper was to explore the key genes and pathogenesis of ischemic stroke(IS) by bioinformatics, and predict the potential traditional Chinese medicines for IS. Based on the gene-chip raw data set of GSE22255 from National Center of Biotechnology Information(NCBI), the article enrolled in 20 patients with ischemic stroke and 20 sex-and age-matched controls, and differentially expressed genes(DEGs) were screened based on R language software. The DAVID tool and R language software were used to perform gene ontology(GO) biological process enrichment analysis and Kyoto encyclopedia of genes and gnomes(KEGG) pathway enrichment analysis. The DEGs were imported into STRING to construct a protein-protein interaction network, and the Molecular Complexity Module(MCODE) plug-in of Cytoscape software was used to visualize and analyze the key functional modules. Moreover, the core genes and the medical ontology information retrieval platform(Coremine Medical) were mapped to each other to screen the traditional Chinese medicines and construct drug-active ingredient-target network. Compared with healthy controls, 14 DEGs were obtained, of which 12 genes were up-regulated and 2 genes were down-regulated. DEGs were mainly involved in immune response, inflammatory process, signal transduction, and cell proliferation regulation. The interleukin-17(IL-17), nuclear factor kappaB(NF-κB), tumor necrosis factor(TNF), nucleotide binding oligomerization domain(NOD)-like receptor and other signaling pathways were involved in KEGG pathway enrichment analysis. The key modules of the DEGs-encoding protein interaction network mainly focused on 7 genes of TNF, JUN, recombinant immediate early response 3(IER3), recombinant early growth response protein 1(EGR1), prostaglandin-endoperoxide synthase 2(PTGS2), C-X-C motif chemokine ligand 8(CXCL8) and C-X-C motif chemokine ligand 2(CXCL2), which were involved in biological processes widely such as neuroinflammation and immunity. TNF and JUN were the key nodes in this module, which might become potential biological markers for diagnosis and prognosis evaluation of IS. The potential traditional Chinese medicines for the treatment of IS includes Salviae Miltiorrhizae Radix et Rhizoma, Croci Stigma, Scutellariae Radix, and Cannabis Fructus. The occurrence of stroke was the result of multiple factors. Dysregulation of genes and pathways related to immune regulation and inflammation may be the key link for the development of IS. This study provided research direction and theoretical basis for further exploring the mechanism of action of traditional Chinese medicine in the treatment of IS and searching for potential drug targets.

Coenzyme Q deficiency causes impairment of the sulfide oxidation pathway.

Coenzyme Q (CoQ) is an electron acceptor for sulfide-quinone reductase (SQR), the first enzyme of the hydrogen sulfide oxidation pathway. Here, we show that lack of CoQ in human skin fibroblasts causes impairment of hydrogen sulfide oxidation, proportional to the residual levels of CoQ. Biochemical and molecular abnormalities are rescued by CoQ supplementation in vitro and recapitulated by pharmacological inhibition of CoQ biosynthesis in skin fibroblasts and ADCK3 depletion in HeLa cells. Kidneys of Pdss2kd/kd mice, which only have ~15% residual CoQ concentrations and are clinically affected, showed (i) reduced protein levels of SQR and downstream enzymes, (ii) accumulation of hydrogen sulfides, and (iii) glutathione depletion. These abnormalities were not present in brain, which maintains ~30% residual CoQ and is clinically unaffected. In Pdss2kd/kd mice, we also observed low levels of plasma and urine thiosulfate and increased blood C4-C6 acylcarnitines. We propose that impairment of the sulfide oxidation pathway induced by decreased levels of CoQ causes accumulation of sulfides and consequent inhibition of short-chain acyl-CoA dehydrogenase and glutathione depletion, which contributes to increased oxidative stress and kidney failure.

n-Butanol extract of Rhynchosia volubilis Lour: a potent spermicidal agent In Vitro / 华中科技大学学报（医学）（英德文版）

Rhynchosia volubilis Lour has been a major drug in a folk prescription for contraception in China, whereas its mechanism remains unknown. Its antifertility effects on male mice and antimicrobial activities on sexually transmitted infection (STI) pathogens were previously reported. This study was undertaken to develop the n-Butanol extract of Rhynchosia volubilis Lour (BERVL) as a spermicidal agent with STI prevention. The spermicidal activities of BERVL with different doses were assessed using selected high-motile sperms of normal human semen samples, and their inhibitory effects on Lactobacillus acidophilus were determined. The mechanism of the spermicidal activity was explored by aqueous Eosin Y and Hoechst 33342/PI staining. The results showed spermicidal activities and inhibitory effects of BERVL on Lactobacillus acidophilus were dose-dependent. Dose of 90 mg/mL BERVL terminated all progressive sperm motility within 2 min, and had slight inhibitory effect on Lactobacillus acidophilus, suggesting it was an effective and safe dose for contraception use. About 80% sperms exposed to BERVL displayed changes consistent with high permeability of head membrane. It is concluded that BERVL as spermicide has advantages over N-9 with strong ability to instantaneously kill human sperm and possesses light inhibitory effect on Lactobacillus acidophilus.

Bipolar transurethral resection of the prostate versus monopolar transurethral prostatectomy: a pathological study in a canine model / 中华男科学杂志

<p><b>OBJECTIVE</b>To compare the postoperative depths of the coagulation zones and pathological changes between bipolar transurethral resection of the prostate with plasmakinetic energy (PKRP) and monopolar transurethral prostatectomy (TURP) in canines.</p><p><b>METHODS</b>Twenty-five male dogs were randomly divided into a PKRP group (n = 12), a TURP group (n = 12) and a sham-operation control group (n = 1). The dogs were sacrificed, their prostates harvested at 0 week (immediately after surgery), 1 week, 2 weeks and 8 weeks postoperatively and sectioned for pathologic analysis and measurement of the coagulation zones.</p><p><b>RESULTS</b>At 0, 1 and 2 weeks after the operation, the coagulation depths were (237.73 +/- 20.12) microm, (113.03 +/- 16.65) microm and (106.01 +/- 16.36) microm in the PKRP group, and (200.75 +/-19.34) microm, (129.46 +/- 17.81) microm and (116.04 +/- 25.67) microm in the TURP group (P < 0.01). At 8 weeks, the coagulation zones completely peeled off and the wounds were covered by regenerated urothelial in both of the groups. At 0, 1, 2 and 8 weeks, different inflammatory reactions were observed in the prostates of the PKRP and TURP groups, with some glandular lumens beneath the coagulation zones expanded and epithelia damaged. However, none of these phenomena occurred in the sham-operation control group.</p><p><b>CONCLUSION</b>Pathologically, PKRP and TURP inflicted basically similar effects on the prostate of the canine. However, the coagulation zone was deeper intraoperatively and became thinner postoperatively with the former than with the latter, which suggests that PKRP causes less bleeding and less penetrative thermal damage than TURP.</p>
