Research progress of the regulation of cochlear sensitivity to noise by circadian rhythm / 生理学报

High level noise can damage cochlear hair cells, auditory nerve and synaptic connections between cochlear hair cells and auditory nerve, resulting in noise-induced hearing loss (NIHL). Recent studies have shown that animal cochleae have circadian rhythm, which makes them different in sensitivity to noise throughout the day. Cochlear circadian rhythm has a certain relationship with brain-derived neurotrophic factor and glucocorticoids, which affects the degree of hearing loss after exposure to noise. In this review, we summarize the research progress of the regulation of cochlear sensitivity to noise by circadian rhythm and prospect the future research direction.

Evaluation of the rationality and feasibility of the grouping method for centralized procurement of insulin drugs in Wuhan based on the results of questionnaire survey among endocrinology physicians / 中国药房

OBJECTIVE To investigate t he attitude of endocrinology physicians to clinical conversion and substitution of insulin drugs ，and to provide basis for improving the centralized procurement program of insulin. METHODS The proportion of convertible and substitutable insulin recognized by endocrinology physicians was investigated by questionnaire from 4 dimensions： intergenerational level ，bargaining group level ，common name level and brand/specification level. The subjects were endocrinology physicians in the third grade class A general hospitals in Nanchang. RESULTS A total of 89 questionnaires were successfully distributed，accounting for 80.2％ of the on-the-job endocrinology physicians （111 in total ）in the third grade class A general hospitals in Nanchang. Eighty-nine questionnaires were collected ，one of which was invalid ，and the effective rate was 98.9％. At the intergenerational level ，93.2％ of endocrinology physicians preferred insulin analogues. At the bargaining group level ，the weighted average of the convertible ratio between group 3 and group 4 approved by physicians was 63.9％. At the levels of common name and brand/specification ，the weighted averages of convertible proportion of each group were more than 70％. CONCLUSIONS The method of insulin grouping in Wuhan is reasonable which can complete clinical conversion and substitution of insulin in the group safely. It is suggested to cancel long-acting human insulin group. The weighted average of the proportion of convertible and substitutable drugs in the group is high. It is suggested to increase the agreed purchase volume of insulin and conduct“volume price linked ”negotiations. When the surveyed physicians choose the initial treatment scheme of insulin ，they pay more attention to the factors such as efficacy and safety ，so the replacement of insulin should be based on the clinical efficacy and drug safety.

Anti-testicular Inflammation Mechanism of Wuzi Yanzongwan Based on Network Pharmacology / 中国实验方剂学杂志

ObjectiveTo explore the anti-testicular inflammation mechanism of Wuzi Yanzongwan through network pharmacological analysis and experimental verification. MethodThe active ingredients of Wuzi Yanzongwan were searched in the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and their targets were predicted via SwissTargetPredicition. GeneCards and Online Mendelian Inheritance in Man （OMIM） were used to obtain the known targets for the treatment of testicular inflammation. STRING 11.0 was employed to construct the protein-protein interaction （PPI） network， and Cytoscape 3.7.1 to construct the “herbal medicine-active ingredient-target” network of Wuzi Yanzongwan and “active ingredient-disease target” network. Metascape was used for gene ontology （GO） annotation and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment of signaling pathways. ResultA total of 72 active ingredients and 624 potential targets of Wuzi Yanzongwan were screened out， and 196 key targets were identified for the treatment of testicular inflammation by Wuzi Yanzongwan. The results of GO annotation showed that the anti-testicular inflammation targets of Wuzi Yanzongwan were involved in the biological processes such as the response to molecule of bacterial origin， the positive regulation of response to external stimulus， and the response to extracellular stimulus. KEGG pathway enrichment revealed that the major pathways associated with the treatment （P<0.01） included the pathways in cancer， epidermal growth factor receptor （EGFR） tyrosine kinase inhibitor resistance， transcriptional misregulation in cancer， calcium signaling pathway， apelin signaling pathway， and NOD-like receptor signaling pathway. Wuzi Yanzongwan may exert the anti-testicular inflammation effect by inhibiting the activation of the NLR family pyrin domain-containing 3 （NLRP3） inflammasome pathway to alleviate the inflammatory response， which verifies the prediction results based on network pharmacology to a certain extent. ConclusionThe inhibitory effect of Wuzi Yanzongwan on testicular inflammation is multi-target， multi-pathway， and multi-mechanism. The findings of this study provide evidence support for the clinical application of Wuzi Yanzongwan.

Study on quality grade evaluation of Andrographis Herba based on principal component clustering and PLS regression / 中草药

Objective: To combine macroscopical characteristic indices and chemical indices of Andrographis Herba to evaluate its quality grade. Methods: Both macroscopical characteristic indices and chemical indices (the content of four active diterpenoids and the content of ethanol-soluble extractives) of different batches of Andrographis Herba were determined. The macroscopical characteristic indices were encoded using the method of numerical taxonomy, and the content of four active diterpenoids were determined by HPLC. To screen out the appropriate indices for classification, the correlational analyses were conducted between encoded macroscopical characteristic indices and chemical indices. The quality grade was made by principal component clustering analysis according these evaluation indices, and then was analyzed through partial least squares discriminant analysis (PLS-DA). Furthermore, a partial least squares (PLS) regression was constructed for the quality grade prediction of Andrographis Herba. Results: It showed that the samples could be divided into three grades according to the principal component clustering analysis, and was reasonable evaluating by PLS-DA. The PLS regression model for quality grade of Andrographis Herba was constructed as follows: grade Y=3.761-0.020×the leaf content-0.388×the content of andrographolide-1.117×the content of neoandrographolide-0.274×the content of deoxyandrographolide-0.287×the content of 14-deoxy-11,12-didehydro-andrographolide-0.302×the content of four active diterpenoids-0.104×the content of ethanol-soluble extractives-0.015×the color of stem-0.008 4×the color of leaf-0.003×the diameter of base part of stem+0.020×the number of branch+0.137×the diameter of the upper stem+0.011×plant height, if Y=0.7-1.3, the predicted quality was grade A, if Y=1.7-2.3, then B grade, and if Y=2.7-3.3, C grade or qualified product. Conclusion: The model of grade evaluation we constructed using principal component clustering analysis combing with PLS regression analysis performed well, which was applicable in evaluating the quality grade of Andrographis Herba and other traditional Chinese medicines. It also provided a new strategy for study on grade standards of traditional Chinese medicines.

Affordability Evaluation for 3 Kinds of Anti-tumor Targeted Drugs:Taking Hubei Province as an Example / 中国药房

OBJECTIVE:To evaluate the affordability of 3 anti-tumor targeted drugs gefitinib,trastuzumab and sunitinib in ur-ban and rural residents of Hubei province,and to provide reference for medical insurance price admission of anti-malignant tumor targeted drugs in China. METHODS:Referring to the incidence of malignant tumor stated in statistical yearbook of Hubei province and income data of urban and rural residents in Hubei province,based on the policy of reducing the price of imported drugs by 50% mentioned in the national drug price negotiations,and assume the drugs are included in the medical insurance reimbursement list,WHO/HAI standard survey method,catastrophic expenditure evaluation method and poverty effect evaluation method were ad-opted to calculate the affordability of 3 drugs. RESULTS:According to WHO/HAI standard survey method,increment of payment for 3 drugs were 64.00%-74.00% before and after 50% discount and reimbursement. According to catastrophic expenditure evalua-tion method,50% discount of gefitinib and reimbursement gefitinib,trastuzumab and sunitinib in urban area would result in cata-strophic expenditures of 20.00%、59.28% and 35.48% patients;in rural area,would result in catastrophic expenditures of 50.63%、74.72% and 75.93% patients. According to poverty effect evaluation method,50% discount of 3 drugs and reimbursement caused less than 31.95% urban and rural patients falling to poverty. CONCLUSIONS:Fifty percentage discount of 3 anti-tumor targeted drugs mentioned in the national drug price negotiations cause the economic burden more serious for rural residents than urban resi-dents. In the formulation of policies,the corresponding reimbursement ratio should be adjusted according to urban and rural areas, drug price and disease types for a balance of patients with different economic burden.

Analysis of long-term care service system in the United States and its implications to China / 中国卫生政策研究

This paper summarizes the kinds of long term care facilities, service delivery organization, service model, service role and experience of long-term service system in the United States. It provides referral implications for China to explore and establish its own long-term care service system. . There is a variety of long-term care services such as short and long-term stay, adult day care, and home care services, with a gradual change from institutional services to home and community ones. Long-term care services are provided by paid both formal and mostly unpaid informal caregivers. Informal family caregivers are most frequently daughters (29. 3%), followed by spouses with (21. 2%). With the increased availability of the family and community-based services, the family caregivers are more likely to share long term care services with the paid formal ones. The United States has a well-structured long-term care service system whose access mechanism is rigorous and systematic, emphasizing the evaluation of service quality and effectiveness. Moreover, the U. S. long term care service system pays more attention on elders' wishes, respecting their preferences and rights of choice on the services. Based on the experience of the United States, China should primarily focuses on establishing a family and community-based long term care service system with a variety of service delivery facilities, give a full play to the community health facilities, social partners, and families. The Chi-nese government should not only give a focus to the service institutions and content diversification, but should as well establish a sound and detailed assessment and evaluation standard system to access the services and assure the effec-tiveness of service quality with a humanized concern.

Progress of clinical trials in Alzheimer's disease drugs / 药学学报

Alzheimer's disease (AD) is a chronic progressive neurodegenerative disease. The pathogenesis of AD is unclear, and it is presently incurable. Medicines currently available for AD treatment are only for improving the cognitive symptoms, but not able to stop or delay disease progression. Here, we summarized the interventions in early phases of AD in clinical trial. As a complex disease, AD is difficult to be restored through a treatment on a single target. Multi-target and cocktail drugs might be a strategy for development of AD therapies. In addition, AD is characterized by progressive neuronal loss in the cortex and hippocampus. The induction of neurogenesis by small molecule compounds has drawn attention in the AD field. The study of natural products in China is leading the way in the AD world. Numerous natural products have been identified for pharmacological effects on multi-targets in the regulation of neurogenic activity, which may open up a new avenue for AD treatments.

Effect and mechanism of Bushen Huoxue recipe on ovarian reserve in mice with premature ovarian failure / 华中科技大学学报（医学）（英德文版）

The aim of the present study was to explore the effect and mechanism of Bushen Huoxue recipe (BHR) on ovarian reserve in mice with premature ovarian failure (POF). Mice were divided into 3 groups: normal group, model group and BHR group. Intraperitoneal injection of cyclophosphamide was performed to create the POF model. Primordial follicular (PDF) number, ovarian wet weight, ovarian index, and estrous cycle were analyzed to evaluate the effect of BHR on POF. Meanwhile, the mRNA and protein level of Mouse Vasa Homologue (MVH) in the bone marrow, peripheral blood and ovary were detected, to explore the underlying mechanism of the treatment efficacy of BHR on ovarian reserve. By the time of BHR treatment for 28 days, BHR increased the PDF number and shortened the estrous cycle of POF mice. BHR also decreased the mRNA level of MVH in the bone marrow, and increased mRNA and protein level of MVH in the ovary of POF mice. Our results demonstrated a treatment efficacy of BHR on POF mice, and revealed that BHR might repair the dysfunction of germline stem cells in the bone marrow, and thus to improve the ovarian reserve and enhance the ovarian function of POF mice through neo-oogenesis.

Effects of Bu-Shen-An-Tai recipe and its two components on endometrial morphology during peri-implantation in superovulated mice / 华中科技大学学报（医学）（英德文版）

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.
