Acupuncture is a traditional empirical medicine, and evidence-based medicine(EBM) is a new medical method and development of the empirical medicine. Since 1990s, Chinese acupuncture workers began to absorb and use the methods and principles of EBM to guide acupuncture clinical research and practice. Now more and more domestic acupuncture clinicians use and follow the methods and principles of EBM. On the systemic review of acupuncture-associated articles in Cochrane library, previously effective acupuncture therapy lacks adequate evidences, which may be related to the low quality of randomized controlled trials(RCTs). In the future, only developing specialized team of acupuncture clinical research and clinical research center can radically elevate the levels of acupuncture clinical research and evaluation. Meanwhile, developing China's evidence-based acupuncture should base itself on the characteristics of acupuncture, such as emphasis on original research in ancient books,high-quality single RCTs and systemic review of non-randomized researches.

Objective To observe the therapeutic effect of acupuncture combined with rehabilitation on dysphagia after stroke at differentstage. Methods According to the randomized trial principle, 155 cases were divided into two groups: control group (n=80) and observationgroup (n=75). The control group was treated with rehabilitation training, and the observation group was treated with acupuncture and rehabilitationtraining, 5 times every week for 4 weeks. The two groups were assessed by TCM swallowing assessment scores and Kubota testbefore and after treatment. Results According to Kubota test, the total rate was 66.67% in the control group and 89.33% in the observationgroup with a significant difference between the groups (P<0.001). In the observation group, the total rate was 90.48% at acute stage and88.89% at the convalescence stage with a significant difference (P<0.01). According to TCM swallowing assessment, the total rate was64.00% in the control group and 74.67% in the observation group with no significant difference between the groups (P<0.05). In the observationgroup, the total rate was 90.48% at acute stage and 68.52% at the convalescence stage with a significant difference (P<0.001). ConclusionAcupuncture combined with rehabilitation facilitates to improve the swallowing function in stroke patients following dysphagia especiallyat acute stage.

Objective: To assess the implementation of National Leprosy Control Plan (2011-2020) in Zhejiang Province, so as to provide insights into leprosy control. Methods: Leprosy control data were collected from the National Leprosy Management Information System of China, and health administrative sectors, centers for disease control and prevention and professional leprosy control institutions at each level in Zhejiang Province. According to the scheme for the final evaluation of National Leprosy Control Plan (2011-2020), the implementation of 12 indicators in Zhejiang Province in 2020 was investigated, including the current number of leprosy patients, prevalence of leprosy, proportion of training on leprosy control skills, proportion of regular leprosy treatment, proportion of treatment of adverse reactions, annual examination rate of close contacts, proportion of early case identification and awareness of leprosy control knowledge. Results: There were 50 registered leprosy cases in Zhejiang Province by the end of 2020, with a decrease of 50.98% relative to in 2010. The prevalence of leprosy was less than 1/105 in 93 counties (districts) of Zhejiang Province, and the rate of training on leprosy control skills, rate of regular leprosy treatment, rate of treatment of adverse reactions, annual examination rate of close contacts, rate of early case identification were all 100% in Zhejiang Province. There were no new confirmed cases with diagnosis of leprosy having grade 2 deformity or disability, or no new cases with deformity or disability within 2 years following anti-leprosy therapy. In addition, the awareness of leprosy control knowledge was 91.67% among the public and 98.12% among the close contacts. All of the 12 indicators reached the requirements of the National Leprosy Control Plan (2011-2020). Conclusions The implementation of the National Leprosy Control Plan (2011-2020) in Zhejiang Province had achieved the targets defined in the final evaluation of the plan. Intensifying multi-sectoral joint leprosy prevention and control and improving early identification and standardized therapy of leprosy cases are recommended for future leprosy control in Zhejiang Province.

Apoptosis refers to the programmed death process of cells modulated by genes. It plays an important role in promoting the evolution of organisms, regulating the development of multiple systems, and maintaining the stability of internal environment. The major apoptosis pathways include mitochondrial pathways, death receptor pathways, and endoplasmic reticulum pathways. With the rapid development of the scientific research on acupuncture, it’s revealed that cell apoptosis should be closely related to the action of acupuncture. So far, the major apoptosis factors involved in relevant researches are P53, Bcl-2 family, Cyt-C, Caspase, Fas/Fasl, TNFR1/TNF-?, and FADD-Caspase8, and PERK, etc. Via influencing these apoptosis factors or genes, acupuncture can produce various effects in improving tissue ischemia, protecting neural cells, reducing inflammation, and correcting endocrine disorders. This article summarized and reviewed the apoptosis pathways and key factors related to the action of acupuncture, to provide some beneficial references for future studies.

Aim To investigate the proliferation of HSCs stimulated by exogenous TGF-β1 (transforming growth factor betal),observe the effect of TFB(total flavonoids of Bidens Bipinnata L.)on smad2/7,typeⅠcollagen mRNA and protein expression of HSCs and study the protective effect and molecular mechanism of TFB on hepatic fibrosis.Methods HSCs were isolated with collagenase Ⅳ perfusion in situ and density gradient centrifugation. The effect of TFB on cell proliferation was observed by MTT colormetric assay. The auto-secretion of TGF-β1 and synthesis of type Ⅰ collagen were measured by enzyme-linked immuneadsordent assay (ELISA).Moreover,the expression of smad2/7, typeⅠcollagen mRNA and protein was measured by semi-quantitative RT-PCR and Western blot methods respectively.Results TFB could markedly inhibit the proliferation of HSCs of liver fibrosis rats stimulated by TGF-β1 and production of TGF-β1 and type Ⅰ collagen.In addition,TFB treatment could significantly down-regulate smad2 and type Ⅰ collagen mRNA expression and up-regulated smad7 mRNA expression of HSCs Smad2 protein expression of HSCs stimulated by TGF-β1 was also down-regulated by TFB.Conclusion TFB has the protective effect against hepatic fibrosis by inhibiting the activation of TGF-β1 signaling pathway and suppressing the HSC proliferation.

Aim To observe the anti-fibros is effect and mechanism of total flavones of Bidens bipinnata L(TFB) on immunological liver fibrosis in rats.Methods The pig serum was injected into abdominal cavity(0.5 ml,twice a week) for 12 weeks so as to induce hepatic fibrosis,and then the rats were treated with TFB daily for 10 weeks and killed at the 22 nd week.The HA,LN,PCⅢ and CⅣ in serum were assessed by ELISA.Liver samples collected after experiment were stained with hematoxylin-eosin(HE) staining,Masson staining and scored.The expression of ?-smooth muscle actin(?-SMA) in liver was analyzed by immunohistochemistry.The gene expression of TGF-?1 was detected by RT-PCR.Results Compared with model group,TFB treatment significantly reduced HA,LN,PCⅢ,CⅣ content in serum.Liver histology in the TFB treated rats was also improved.Moreover TFB could decrease the expression of protein ?-SMA and TGF-?1 mRNA.Conclusions TFB significantly reduced pig serum-induced liver fibrosis in rats,probably by decreasing the expression of TGF-?1 mRNA and then inhibiting the proliferation of HSC.
