Neurological Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

In recent years， the incidence of neurological diseases has been increasing year by year. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of neurological disorders， identify the breakthrough point of integrating TCM with western medicine， and further standardize the clinical diagnosis and treatment of TCM， the China Association of Chinese Medicine organized neurologists in TCM and western medicine to carry out in-depth discussion on the neurological diseases responding specifically to TCM and integrated TCM and western medicine， such as stroke， headache， vertigo， multiple sclerosis， and epilepsy， aiming to formulate a well-recognized and integrated treatment protocol for TCM and western medicine and improve the efficacy of neurological disorders. Furthermore， the treatment suggestions of the corresponding diseases in TCM and western medicine were proposed to provide references for clinical practice and scientific research.

Xinglou Chengqi Decoction improves neurological function in experimental stroke mice as evidenced by gut microbiota analysis and network pharmacology / 中国天然药物

The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction (XCD) based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion (MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke (IS) to deplete the gut microbiota. High-throughput 16S rDNA gene sequencing, metabonomics technique, and flow multifactor technology were used to analyze bacterial communities, SCFAs and inflammatory cytokines respectively. Finally, as a supplement, network pharmacology and molecular docking were applied to fully explore the multicomponent-multitarget-multichannel mechanism of XCD in treating IS, implicated in ADME screening, target identification, network analysis, functional annotation, and pathway enrichment analysis. We found that XCD effectively improved neurological function, relieved cerebral infarction and decreased the neuronal apoptosis. Moreover, XCD promoted the release of anti-inflammatory factor like IL-10, while down-regulating pro-inflammatory factors such as TNF-α, IL-17A, and IL-22. Furthermore, XCD significantly increased the levels of short chain fatty acids (SCFAs), especially butyric acid. The mechanism might be related to the regulation of SCFAs-producing bacteria like Verrucomicrobia and Akkermansia, and bacteria that regulate inflammation like Paraprevotella, Roseburia, Streptophyta and Enterococcu. Finally, in the network pharmacological analysis, 51 active compounds in XCD and 44 intersection targets of IS and XCD were selected. As a validation, components in XCD docked well with key targets. It was obviously that biological processes were mainly involved in the regulation of apoptotic process, inflammatory response, response to fatty acid, and regulation of establishment of endothelial barrier in GO enrichment. XCD can improve neurological function in experimental stroke mice, partly due to the regulation of gut microbiota. Besises, XCD has the characteristic of "multi-component, multi-target and multi-channel" in the treatment of IS revealed by network pharmacology and molecular docking.

Osthol effects on the proliferation and differentiation of osteoblasts based on endoplasmic reticulum stress / 中国组织工程研究

BACKGROUND: Osthol has been reported to promote osteogenesis by increasing osteoblast proliferation, but the anti-osteoporosis mechanism underlying osthol is poorly understood.OBJECTIVE:To observe the effect of osthol on the proliferation and differentiation of rat osteoblasts in vitro and to explore its mechanism of anti-osteoporosis effect. METHODS: Rat osteoblasts were isolated by secondary enzyme digestion and identified by alkaline phosphatase staining and mineralized nodule staining. There were five groups: blank control, solvent control, β-estradiol as well as low-, medium- and high-dose osthol groups. Cell proliferation was detected by cell counting kit-8 assay, and cell differentiation was evaluated by detection of alkaline phosphatase and mineralized nodule staining. The expression levels of GRP78, PDI and CHOP were detected by western blot assay. RESULTS AND CONCLUSION: Osthol at the concentrations of 1x10-4and 1x10-5mol/L could inhibit osteoblast proliferation. 1x10-4mol/L osthol could increase the activity of alkaline phosphatase in osteoblasts and enhance osteoblastic mineralization. Meanwhile, 1x10-4mol/L osthol was able to down-regulate the expression level of GRP78 and up-regulate the expression levels of PDI and CHOP. To conclude, osthol can promote osteoblast differentiation and inhibit osteoblast proliferation probably by endoplasmic reticulum stress.

Effect of health insurance on direct hospitalisation costs for in-patients with ischaemic stroke in China.

Objectives The aim of the present study was to determine the direct medical costs of hospitalisations for ischaemic stroke (IS) in-patients with different types of health insurance in China and to analyse the demographic characteristics of hospitalised patients, based on data supplied by the China Health Insurance Research Association (CHIRA). Methods A nationwide and cross-sectional sample of IS in-patients with International Classifications of Diseases 10th Revision (ICD-10) Code I63 who were ensured under either the Basic Medical Insurance Scheme for Employees (BMISE) or the Basic Medical Insurance Scheme for Urban Residents (BMISUR) was extracted from the CHIRA claims database. A retrospective analysis was used with regard to patient demographics, total hospital charges and costs. Results Of the 49588 hospitalised patients who had been diagnosed with IS in the CHIRA claims database, 28850 (58.2%) were men (mean age 67.34 years) and 20738 (41.8%) were women (mean age 69.75 years). Of all patients, 40347 (81.4%) were insured by the BMISE, whereas 8724 (17.6%) were insured by the BMISUR; the mean age of these groups was 68.55 and 67.62 years respectively. For BMISE-insured in-patients, the cost per hospitalisation was RMB10131 (95% confidence interval (CI) 10014-10258), the cost per hospital day was RMB787 (95% CI 766-808), the out-of-pocket costs per patient were RMB2346 (95% CI 2303-2388) and the reimbursement rate was 74.61% (95% CI 74.48-74.73%). For BMISUR-insured in-patients the cost per hospitalisation was RMB7662 (95% CI 7473-7852), the cost per hospital day was RMB744 (95% CI 706-781), the out-of-pocket costs per patient were RMB3356 (95% CI 3258-3454) and the reimbursement rate was 56.46% (95% CI 56.08-56.84%). Conclusions Costs per hospitalisation, costs per hospital day and the reimbursement rate were higher for BMISE- than BMISUR-insured in-patients, but BMISE-insured patients had lower out-of-pocket costs. The financial burden was higher for BMISUR- than BMISE-insured in-patients. For BMISUR-insured in-patients, the out-of-pocket payment was 43.54% of total expenses, which means the government should increase the financial investment, raise reimbursement rates and set up differential reimbursements to meet the health needs of in-patients with different income levels. What is known about the topic? Cardiovascular and cerebrovascular diseases are major non-communicable diseases affecting the health of the Chinese population. The China Health Statistics Yearbook (2013) reported that across all in-patients, 195million (5.82%) had been discharged with a diagnosis of cerebrovascular disease. Of these, 118million had IS, accounting for 60.51% of all in-patients with cerebrovascular disease and 54.97% of hospitalisation costs for all cerebrovascular disease in-patients. After the two basic insurance systems, namely the BMISE and BMISUR, had been established, the out-of-pocket expenses for patients were reduced. However, to date there have been no studies investigating how the different types of health insurance (i.e. the BMISE and the BMISUR) affected the costs of treatment of IS in-patients in China. What does this paper add? This paper reports the direct costs for patients diagnosed with IS based on data supplied by the CHIRA. Direct hospitalisation costs depending on the type of insurance cover, age and gender were also evaluated. What are the implications for practitioners? The present study found that the personal financial burden of disease treatment was higher for in-patients insured under the BMISUR than BMISE. For in-patients insured under the BMISUR, the out-of-pocket payment was 43.54% of total expenses, which means the government should increase the financial investment, raise reimbursement rates and set up differential reimbursement rates to meet the health needs of patients with different incomes.

<p><b>OBJECTIVES</b>To explore the protective effects of Tongmai Yizhi Decoction (, TYD), a Chinese herb complex prescription against the impairment of cognitive functions and memory loss in amyloid beta 1-40 (Aβ) peptide and ibotenic (IBO)-induced Alzheimer's disease (AD) model rats.</p><p><b>METHODS</b>The in vivo model was established by injecting Aβand IBO into left hippocampal CA1 area of Sprague-Dawley (SD) rat to mimic AD. Totally 32 SD rats were divided into 4 groups, including sham operation group, AD model group, TYD group [AD rats treated with TYD at the dosage of 19.44 g/(kg•d) for 4 weeks] and huperzine A group [AD rats treated with huperzine A at the dosage of 40.5 μg/(kg•d) for 4 weeks]. Spatial learning and memory level was detected by Morris Water Maze test. Histological morphology in the hippocampus was tested by hematoxylin-eosin (HE) staining. Cyclin-dependent kinase-5 (Cdk5) protein and gene expression level were investigated by Western blot analysis and real-time quantitative polymerase chain reaction (RT-qPCR), respectively.</p><p><b>RESULTS</b>Aβ1-40 and IBO treatment induced longer escape latency of rats, compared with sham operation group from day 25 (P<0.01). However, TYD and huperzine A obviously shortened the escape latency from day 26 (P<0.01). Moreover, the effect of TYD was similar to huperzine A (P>0.05). Furthermore, HE staining also showed that TYD and huperzine A reversed the neuropathological changes in the hippocampus triggered by Aβ1-40 and IBO. TYD and huperzine A effectively reduced the expression levels of Cdk5 protein and gene located in rat hippocampus, compared with the AD model group (P<0.01).</p><p><b>CONCLUSION</b>TYD could be a promising neuroprotective agent for protecting neuron from AD injury through inhibiting Cdk5 expression.</p>

Effect of Jisuikang on Nogo-66 receptor NgR expression in rats with spinal cord injury / 中国组织工程研究

BACKGROUND: Myelin sheath related inhibitors have been found to have great impact on microenvironment of axon regeneration. Traditional Chinese medicine is gradual y becoming a research hotspot on improving microenvironment of nerve regeneration with its advantage on multiple factors and targets. OBJECTIVE: To clarify the effect of Jisuikang on Nogo-66 receptor NgR expression after spinal cord injury. METHODS: 144 rats were randomly divided into six groups: sham surgery group, model group, prednisone group, high-, moderate- and low-dose Jisuikang groups (n=24). Animal models of spinal cord injury were established by the modified Allen’s method in the later five groups. Rats in the prednisone group were daily given 0.06 g/kg prednisone acetate by lavage, once a day. Rats in the high-, moderate- and low-dose Jisuikang groups were daily intragastrically given 12.5, 25 and 50 g/kg Jisuikang, once a day. Rats in the sham surgery and model groups were intragastrically daily given 20 mL of saline, once a day. Rats in each group were administered drugs until death. RESULTS AND CONCLUSION: Compared with the model group, NgR protein and mRNA expression levels were significantly lower in the prednisone, moderate-and low-dose Jisuikang groups. These data suggested that Jisuikang can improve the recovery of neurological function after spinal cord injury and effectively inhibit NgR protein expression at the site of injury so as to suppress the microenvironment factors harmful to nerve regeneration and further improve the microenvironment of nerve regeneration.

The response rate (PR + NC) of TACE was 83.2% with 1-, 3-, 5-year survival rate of 69.3%, 21.7%, 8.4% after TACE, respectively. The response rate (PR + NC) of TAI was 27.5% with 1-, 2-year survival rate of 11. 6% and 0 after TAI. The Child grade of liver function, color-ultrasonography and alpha-fetoprotein of TACE + RFA group, TACE and TAI were compared. There was no significant difference between each above mentioned index among TACE, RFA or TACE groups.</p><p><b>CONCLUSION</b>Compared with other modalities, transcatheter arterial chemoembolization (TACE) before or after hepatectomy is more effective than other interventional therapies for primary hepatocellular cancer, whereas, if combined with radiofrequency ablation (TAI), it is much more effective than TACE alone.</p>

Analysis on yield and quality of different Houttuynia cordata / 中国中药杂志

<p><b>OBJECTIVE</b>To study the yield of different Houttuynia cordata and the changing regularity of their main officinal components in different periods, and provide a basis for harvesting in good time and breeding new varieties.</p><p><b>METHOD</b>The main officinal composition and wet weight of overground parts per acreage of different accessions were determined periodically. The plot yields were tested when harvested and analyzed by analysis of variance.</p><p><b>RESULT</b>The difference of the yields of different accessions was significant. The varying tendency of the content of main officinal component methyl nonyl ketone and its total content per acreage of different accessions were different.</p><p><b>CONCLUSION</b>The integrate characters of Qionglai and Wangyu wild accessions are relatively better, worthy to be widely applied in production.</p>
