ObjectiveTo observe the effect of cluster needling of scalp acupuncture combined with rehabilitation(Tang's Approach) on learning and memory and the expression of hippocampus microtubule-associated protein-2 (MAP-2) in young rats after hypoxic ischemic brain damage (HIBD).Methods80 Wistar young rats were randomly divided into 5 groups: sham group, model group, scalp cluster acupuncture group, environmental stimuli group, and acupuncture with rehabilitation group, 16 rats in each group. Each group was divided into 2 subgroups on the 14th and 28th days after the model. HIBD young animal model was made by ligating left common carotid artery and inspiring 8% oxygen and 92% nitrogen mixture. Learning and memory was observed by Morris water maze, and MAP was observed by immunohistochemistry.ResultsThe results of the Morris water maze test showed that there was significant difference in ability of place navigation and space exploration in the scalp cluster acupuncture group, the environmental stimuli group, and the acupuncture with rehabilitation group compared with the model group (P<0.05), and there was significant difference in ability of place navigation and space exploration in the acupuncture with rehabilitation group compared with the scalp cluster acupuncture group and the environmental stimuli group (P＜0.05). The results of immunohistochemistry showed that there was significant difference in the expression of MAP-2 in the scalp cluster acupuncture group, the environmental stimuli group, and the acupuncture with rehabilitation group compared with the model group (P<0.05), and there was significant difference in the expression of MAP-2 in the acupuncture with rehabilitation group compared with the scalp cluster acupuncture group and the environmental stimuli group (P＜0.05). ConclusionLearning and memory of young rats after hypoxic ischemic brain damage can be improved by Tang's Approach which is possibly related with expression of MAP-2 in hippocampus.

Objective To explore the effects of cluster needling of scalp acupuncture combined with rehabilitation (Tang's Approach) onforelimb motor function and expression of synaptophysin and growth-associated protein (GAP-43) in rats after focal cerebral ischemia.Methods Endothelin-1(ET-1) was used to induce focal cerebral ischemia model in rats with forelimb dysfunction. The rats were randomlydivided into 5 groups: sham operation group, model group, rehabilitation group, acupuncture group, and acupuncture with rehabilitationgroup, each group was divided into 4 subgroups by 3 d, 7 d, 14 d, and 21 d. 24 hours after modeling, the cluster needle of scalp point withskilled forelimb reaching was trained in the acupuncture with rehabilitation group, skilled forelimb reaching was trained in the rehabilitationgroup, and the cluster needle of scalp point only were punctured and stimulated in the acupuncture group. But the model group had no intervention.The success rates of forelimb reaching were analyzed and immuno-histochemical technique was used to observe the expression ofsynaptophysin and GAP-43 in cortical ischaemic lesions of the rats in each group at different time points. Results At different time pointsafter the treatment, the successful rate of forelimb reaching in the acupuncture with rehabilitation group was higher than the model group, rehabilitationgroup, and acupuncture group (P<0.05). Conclusion The cluster needling of scalp acupuncture combined with rehabilitationcan promote recovery of forelimb motor function in rats after focal cerebral ischemia, which may associate with the expression of synaptophysinand GAP-43 in cortex surro`unding following focal cortical ischaemic lesions.

Objective To explore the effects of task-oriented training on forelimb motor function and expression of synaptophysin andgrowth associated protein (GAP)-43 in rats after focal cerebral ischemia. Methods Endothelin-1 (ET-1) was used to induce focal cerebralischemia model in rats with forelimb dysfunction. The rats were randomly divided into 4 groups: sham operation group, model group,task-oriented training group and treadmill running group, each group was divided into 4 subgroups by 3 d, 7 d, 14 d, and 21 d. 24 hours aftermodeling, the rats in task-oriented training group were trained with forelimb reaching and the rats in the treadmill running group weretrained by treadmill, and the model group had no intervention. Motor function of rats was evaluated by net screen test, and immunohistochemistrystaining was used to observed the expression of GAP-43 and synaptophysin in cortical ischemia lesions of the rats in each groupat different time points. Results The scores of behavioral tests were better in the task-oriented training group than in the model group (P<0.01) and the treadmill group (P<0.05) on the 14th and 21st days after modeling. The expression of GAP-43 was higher in the task-orientedtraining group than in the model group (P<0.05) and the sham group (P<0.01) on the 7th and 21st days after modeling. The expression ofsynaptophysin was higher in the task-oriented training group than in the model group (P<0.05) and the sham group (P<0.05) on the 14th andthe 21st days after modeling. Conclusion Task-oriented training can facilitate the recovery of forelimb motor function of rats after focal cerebralischemia, and it may be partially related to the up-regulation of expression of GAP-43 and synaptophysin in peri-infarction cortex.

In this research paper , we intend to come up with making proposals to centralized drug procurement in each province in China .Document consultations about drug centralized procurement in each province in 2015 were used to collect information and this information was further summarized and comparatively analyzed .From the results , it's clear that each province has designed an implementation plan based on the No .7 and the No.70 documents. When carrying out the centralized procurement , the practice on organizational structure , procurement classification , procurement with quantity , drug distribution and payment collection in each province vary from one province to anoth-er.In view of the observed results , it is worthwhile that each province should centralize its tender and procurement system , explore new ways for involving health insurance department in centralized drug procurement , implement joint reformation for public health services , medical insurance and medical production-circulation , and oppose regional protection in any form to ensure the success and equity of centralized drug procurement .

Objective:To improve the centralized bidding and procurement of drugs in China .Methods:By u-sing literature review , comparative analysis and field investigation , this study collected and analyzed implementation plans and regulations of the centralized bidding and procurement of drugs in 2015 .Results and Conclusions:Progress of centralized bidding procurement practice was mixed and there were differences in the scope of implementation , quality level classification , evaluation system of double envelope bidding , and other aspects among provinces .The government should give full play to the role of medical insurance department in drug procurement and group purcha -sing , develop a relatively comprehensive drug quality evaluation system , and speed up the evaluation of the consisten-cy of generic drugs .

Objective To investigate the effect of MS-275, an histone deacetylase ( HDAC ) inhibitor, on acute liver failure ( ALF ) induced by D-galactosamine and lipopolysaccharide in mice. Methods Thirty specific pathogen free (SPF) C57BL/6 male mice were randomly and equally divided into control, ALF model and MS-275 groups. ALF model was induced by D-galactosamine ( D-Gal ) and lipopolysaccharide (LPS), and the mice in MS-275 group received MS-275 (1 mg/kg) at 2 h before the induction of ALF.Serum and liver samples of mice were obtained at 24 h after ALF induction.The serum levels of ALT, AST, TBil and tumor necrosis factor-alpha ( TNF-α) , interferon γ( IFNγ) , interleukin ( IL )-1β, high mobility group box 1 ( HMGB1 ) were tested by biochemical methods or ELISA kit, respectively.The expression of HDAC1, HDAC3, acetylation of histone H3, H4, P65, acetylation and phosphorylation of P65 in liver were detected by Western blotting.The changes of histology in liver was detected by HE staining, and the translocation of P65 in liver was detected by immunohistochemistry. Comparison of variables among the groups was performed using t test.Results MS-275 inhibited the infiltration of inflammatory cells and improved the pathological changes of liver tissue.Compared with ALF group, serum ALT, AST, TBil levels were decreased in MS-275 group ( t =-22.215, -11.914 and-12.160, all P<0.05), but still higher than those in the control group (t=14.852, 11.692 and 8.333, all P<0.05); serum TNF-α, IFNγ, IL-1β, HMGB1 levels were also significantly decreased in MS-275 group (t=-7.926, -3.427, -2.475 and -5.920, all P<0.05), but TNF-αand IFNγwere still higher than those in the control group (t=5.541 and 5.514, all P<0.05).Compared with control group, the expression of class I HDAC in liver tissue was significantly decreased in MS-275 group ( t=-3.676 and-10.576, P<0.05), while the expressions of acetylation of histone H3, H4 and P65 were significantly increased (t=3.976, 5.559 and 4.588, all P<0.05).MS-275 inhibited the translocation of P65 from cytoplasm to the nucleus.Conclusion MS-275 can protect liver from acute failure in mice through enhancing the acetylation levels of non-histones.

Objective:The paper aims to provide recommendations for improving the essential medicines’ cen-tralized bidding procurement and quantity-based pricing policy. Methods: Based on the documents and literature on essential medicines’ centralized bidding procurement, we analyzed the factors which have a great impact on implemen-tation of the quantity-based pricing in essential medicines’ centralized procurement using the text research, semi-structured interview questionnaire and on-phone interviews. Results:The quantity-based pricing needs to define a ge-neric name and specific dosage form of drugs in the essential medicines’ centralized procurement. Its implementation was mainly influenced by the following factors:the procurement area accessibility, the pharmaceuticals category, dis-ease and drug alternative procurement methods and cycle, the payment and settlement time, and irregularities in the procurement process. Suggestions:During this implementation, we also need to clearly predict the quantity and pro-curement method, set up a proper policy environment for a quantity-based pricing, cancel the price linkage mecha-nism, strictly put into practice the payment deadline, employ a unique billing method and strengthen the information construction for the provincial centralized procurement platform. Some medicines’ quantity-based pricing should be carried out in the chosen pilots for laying a good foundation for its promotion.

BACKGROUNDTo evaluate the clinical efficacy and toxicity of GP (gemcitabine+cisplatin) and NP (navelbine+cisplatin) regimens in the treatment of advanced non-small cell lung cancer (NSCLC).

METHODSSeventy-six cases of advanced NSCLC were enrolled. Among them, 36 received GP (gemcitabine 1.0 g/m² D1,8,15+cisplatin 30 mg/m² D1-3), meanwhile 40 were administrated NP regimen (navelbine 30 mg/m² D1,8+cisplatin 30 mg/m² D1-3).

RESULTSThe overall response rates of GP and NP were 52.8% and 47.5% respectively (P > 0.05), and the median survivals were 9.8 and 8.7 months respectively (P > 0.05). The main toxicity was hematological toxicity. The incidences of leukopenia were 58.3% and 92.5% in GP and NP respectively (P < 0.01), and those of grade III-IV leukopenia were 16.7% and 52.5% respectively (P < 0.01 ). There was no significant difference in thrombocytopenia incidence between the two groups, however, GP group had a remarkably higher incidence of grade III-IV thrombocytopenia (33.3%) than NP group ( 10.0% ) (P < 0.05 ).

CONCLUSIONSEfficacy of GP regimen is similar to that of NP and both of them can be well tolerated by patients.

This study selected the top five general hospitals in the United States of America, collected the practice information of acupuncturists through the official website, and analyzed the professional department, expertise, professional title, education background, residency, fellowship, board certification, etc. of these acupuncturists to understand the practice situation of acupuncturists in the hospitals. The results of the study showed the practice of acupuncturists in the United States of America is improving. With further localization, locally trained acupuncturists have gradually become the main body of acupuncturists; acupuncture treatment is still mainly for analgesia, but the scope of treatment continues to expand, and departments that accept acupuncturists are gradually increasing. However, the group of licensed acupuncturists is still a minority in the group of acupuncturists in the United States of America. Native American physicians still use acupuncture as an alternative option and neglect to obtain a license. The entry barrier for acupuncturists still needs to be raised.
