Multilateral mechanisms are important platforms and vehicles for cooperation in traditional medicine.Relying on multilateral platforms,China is able to enhance the international influence of the domestic traditional Chinese medicine and form synergies with other member countries to enhance regional or cross-regional radiation effects in order to promote sustainable development of traditional medicine around the world.This paper focuses on China's participation in major multilateral health cooperation mechanisms,including global initiatives(WHO-led global cooperation framework,the Belt and Road Initiative),regional multilateral mechanisms(ASEAN countries,China-Japan-Korea Health Cooperation Mechanism,Shanghai Cooperation Organization(SCO),The Greater Mekong Subregion(GMS)),and cross-regional multilateral mechanisms(BRICS,Forum On China-Africa Cooperation(FOCAC),G20),and sorts out the cooperation policies and actions in traditional medicine under different mechanisms,to analyze the characteristics and challenges of the existing mechanisms in traditional medicine cooperation,and to provide evidence for China's promotion on multilateral cooperation in traditional medicine.

Objective Mutated inbred animal model is introduced to the practical course of genetic diagnosis in the hope that medical students are able to apply what they have learned to clinical cases, based on a deep understanding of principle and technology on gene mutation detection. Methods We integrated DNA extraction, polymerase chain reaction, agarose gel electrophoresis, and gel imaging analysis into a comprehensive experiment and arranged 4-year-programme undergraduates majoring in preclinical medical sciences to conduct it with the purpose of investigating the internal relations between phenotype and genotype in a hairless Uncv mouse model. Subsequently, the questionnaire aimed at evaluating learning effect on the part of students was handed out and their feedbacks were analyzed. Results More than 90% of respondents are satisfied with the general learning effect. Especially, 98. 7% of students support the enhancing effect of the new teaching mode on their research skills and 96% consider the practical course helpful to their problem-solving ability. Conclusions The introduction of mutated inbred animal model to the practical system of molecular diagnostics proves beneficial to boost students' learning effect and scientific research quality. Our practice also provokes thoughts on the further utilization of animal models in teaching system of medical sciences.

Objective To explore the effect of miRNA-195 (miR-195) on Smad7 expression and rat hepatic stellate cells line (HSC-T6) activation incuced by transforming growth factor-β1 (TGF-β1).Methods HSC-T6 were cultured in vitro,with 5 ng · mL-1 TGF-β1 as an injury factor simulating the rats liver fibrosis models.The cells divided into six groups:control group,model group (TGF-β1 group),miR-195 mimic experimental group,miR-195.mimic NC experimental group,miR-195 inhibitor experimental group and miR-195 inhibitor NC experimental group.After the HSC-T6 treated with 5 ng · mL-1 TGF-β1for 24,48,72 h,the mRNA expression of miR-195,Smad7,and α-SMA was detected by Real-time PCR.The protein expression of Smad7 was detected by Western blot.Results Under the induced by TGF-β1,the expression of miR-195 increased gradually (P ＜ 0.01),the expression of Smad7 showed a decreasing trend (P ＜ 0.05),and the expression of oα-SMA was gradually upregulated (P ＜ 0.01) with time.Compared with the model group,miR-195 mimic could promote activation of HSC-T6 induced by TGF-β1,and increase miR-195,α-SMA mRNA expression (all P ＜0.01),as well as reduce Smad7 mRNA and protein expression (all P ＜0.01);while miR-195 inhibitor could inhibit activation of HSC-T6 induced by TGF-β1,decrease miR-195,α-SMA mRNA expression (all P ＜ 0.01),as well as upregulate Smad7 mRNA and protein expression (all P ＜ 0.01).Conclusion miR-195 is involved in pro-activation of HSC-T6 by inhibiting Smad7 expression.

Objective To investigate the prevalence and influencing factors of mild cognitive impairment (MCI) among elderly people in communities of Nanning, so as to provide scientific basis for the formulation of MCI early intervention measures. Methods A total of sample of 3 000 elderly people aged 60 or above living in Nanning area were sampled out using the method of cluster random sampling from three communities in Nanning. The Beijing version of the montreal cognitive assessment (MOCA-BJ) was administered by face to face interview. Results 833 MCI patients were detected. The standardized prevalence rate of MCI was 27.27% by the age composition of the population in Nanning in 2010. Single factor analysis showed that there were significant differences(all P<0.05)in the prevalence of MCI in different groups by age, education, occupation, exercise time, sleep time, number of reading, community activities and housework. Multivariate analysis showed that old age, primary education level, occupation of farmer/migrant worker and enterprise personnel/worker were the risk factors of MCI, adequate sleep time, moderate exercise time and reading times were the protective factors of MCI (all P<0.05). Conclusions The prevalence rate of MCI is high among the elderly in Nanning. The elderly with advanced age, primary school education, occupation as farmer/peasant-worker and enterprise personnel/workerare at high risk of developing MCI. Effective measures should be taken as soon as possible to prevent the occurrence and development of MCI.

Objective To monitor the co-infection status of Borrelia burgdorferi sensu lato (R.b.s.1) and spotted fever group Rickettsia (SFGR) in tourist areas of Heilongjiang province.Methods Polymerase chain reaction (PCR) was used to detect the 5S-23S rRNA intergenic spacer of B.b.s.1 and ompA of SFGR in ticks,dynamically collected from tourist areas of Heilongjiang province in 2010.Amplification products from positive ticks were sequenced,and phylogenetic analysis was conducted by Mega 5.0 software package.Results 849 ticks were collected from two tourist points,with the dominant ticks in Tiger Mountain and Jingpo Lake were Ixodes persulcatus and Haemaphysalis concinna.Regarding the Ixodes persulcatus from Tiger Mountain,the infection rates of B.b.s.1 and SFGR were 26.15％ and 10.05％.The infection rate of SFGR was 13.33％ in Haemaphysalis concinna and the B.b.s.1 was tndiscovered in the same ticks from Jingpo Lake.However,the co-infection could only be detected in Ixodes persulcatus of both tourist areas.Surveillance data showed that the major ticks were more likely to be appeared in July at Tiger Mountain and in June at Jingpo Lake.Data from the sequence analysis on B.b.s.1 showed that the B.b.s.1 in tourist areas could be classified into three different genotypes,other than B.garinii and B.afzelii.We first detected B.valaisiana-like group genotype in northeast of China.Results from the sequence analysis of SFGR positive products showed that the two DNA sequences of newly detected agents were completely the same as Rickettsia sp.HL-93 which was detected in Hulin and Rickettsia sp.H820 found in northeast,China.Conclusion The co-infection of B.b.s.1 and SFGR was detected in ticks from the tourist areas of Heilongjiang province,and data from the sequencing of specific fragment showed that various kinds of genotypes existed in this area.However; the rates of co-infectionitis-different according to environment,time and population that contributed to the kinds of and the index of ticks existed in the surveys points,also the infection rate of the ticks was studied.
