  • With the rapid development of Chinese economy, the uncooperativeness between economy and ecological environment has become an obstacle to the progress of the society. Due to the limitations in terms of scale, source of funds and quality, the present ecological compensation mode doesn't realize the planned effects. In this paper, a new framework and mechanism of ecological compensation has been proposed, which could guide the adjustment and improvement of the present policies based on the analysis of implementation to meet the demand for environmental management in Erhai, so as to achieve the co-existence between human beings and nature.

  • Spiraea japonica L. F., a plant species belongs to the Spiraea genus of Rosaceae family, has seven varieties. There are all varieties distributed in Yunnan province of China, and S. japonica var. acuminata and S. japonica var. fortunei were used as the folk medicines to treat malaria and inflammation etc.. Since 1960s, Japanese and Russian scholars obtained C$\_$20/-diterpenoid alkaloids from S. japonica L.F., also Chinese scholars got a series of Hetisine-type C$\_$20/-diterpenoid alkaloids from S. japonica var. fortunei in 1985. Since then, we started the chemical and pharmaceutical studies of this complex. Here we wish to report the bioactive effects of spiramine alkaloids and their derivatives on the platelet aggregation induced by AA, PAF, or ADP.

  • Plasmodium vivax merozoite surface protein-1 (PvMSP1) gene codes for a major malaria vaccine candidate antigen. However, its polymorphic nature represents an obstacle to the design of a protective vaccine. In this study, we analyzed the genetic polymorphism and natural selection of the C-terminal 42 kDa fragment within PvMSP1 gene ($PvMSP1_{42}$) from 77 P. vivax isolates, collected from imported cases of China-Myanmar border (CMB) areas in Yunnan province and the inland cases from Anhui, Yunnan, and Zhejiang province in China during 2009-2012. Totally, 41 haplotypes were identified and 30 of them were new haplotypes. The differences between the rates of non-synonymous and synonymous mutations suggest that $PvMSP1_{42}$ has evolved under natural selection, and a high selective pressure preferentially acted on regions identified of $PvMSP1_{33}$. Our results also demonstrated that $PvMSP1_{42}$ of P. vivax isolates collected on China-Myanmar border areas display higher genetic polymorphisms than those collected from inland of China. Such results have significant implications for understanding the dynamic of the P. vivax population and may be useful information towards China malaria elimination campaign strategies.

  • A tattoo is a cultural form that has been handed down to mankind for a long time. Traditional tattoo customs that have been handed down and developed in the various cultures of mankind have the important value of academic research in various fields such as history, art, society, etc. The Derung people, one of the minorities living in Yunnan Province and nearby areas in the southwest of China, have 'facial tattoo' customs. The traditional culture of the Derung people, which had maintained the form of primitive society until 1949 when the People's Republic of China was established, was passed down through oral tradition, so there are no preserved materials about their tattoo culture, showing the need for research on the culture. Therefore, it was conducted in two ways: a research on modern and contemporary literature and a field trip to Yunnan Province. The exact reason and time of facial tattoo customs are unknown, but the customs disappeared after being banned in 1966 due to the Chinese Cultural Revolution. The symbols and functions of facial tattoos can be largely divided into four categories, including religious worship, coming-of-age ceremonies, aesthetic decorations, and ethnic and social history, through an on-site survey and research by modern and contemporary scholars. And, it is known that women of the Derung People get tattoos from the age of 7 to 8. The design of facial tattoos became more complicated for upper-class women and simpler for lower-class women depending on the area they live. Tattoos are mainly performed by relatives, and mainly bamboo skewers and lixivium extracted from the bottom of the pot are used as the materials. Currently, there are fewer than 25 women of the Derung people with facial tattoos, and most of them are elderly. Therefore, they seem to disappear altogether within a few decades. Therefore, it is urgent to have documentation on the unique facial tattoo culture of the Derung people.

  • Objectives: To assess knowledge of HPV and attitudes towards HPV vaccination among the general female population, government officials, and healthcare providers in China to assist the development of an effective national HPV vaccination program. Methods: A cross-sectional epidemiologic survey was conducted across 21 urban and rural sites in China using a short questionnaire. 763 government officials, 760 healthcare providers, and 11,681 women aged 15-59 years were included in the final analysis. Data were analyzed using standard descriptive statistics and logistic regression. Results: Knowledge of HPV among the general female population was low; only 24% had heard of HPV. Less than 20% of healthcare providers recognized sexually na$\ddot{i}$ve women as the most appropriate population for HPV vaccination. There was high acceptance of the HPV vaccine for all categories of respondents. Only 6% of women were willing to pay more than US $300 for the vaccine. Conclusions: Aggressive education is necessary to increase knowledge of HPV and its vaccine. Further proof of vaccine safety and efficacy and government subsidies combined with increased awareness could facilitate development and implementation of HPV vaccination in China.

  • Aim: Depression is thought to be a predictor of poor survival among cancer patients. In our study, we aimed to investigate the association between depression and survival in patients with gastric cancer. Methods: The subjects were a total of 300 patients aged 20-75 years who had histological confirmed diagnosis of gastric cancer from January 2004 to May 2006. Three months after patients diagnosis, depression was scored using by the Depression Status Inventory (DSI) designed by Willian WK Zung. The follow-up period consisted of a total of 13,643 person-months. A Cox's regression analysis was used to assess the association between depression and survival. Results: The percentage of subjects with depression according to the DSI depression criteria was 31%. Tumor stage and treatment methods were significantly associated with depression of patients. Age (60 years or older), annual income, tumor stage, lymph nodes metastasis and treatment were significantly associated with increased hazard ratio (HR) for gastric cancer survival. The adjusted HR for mortality risk in gastric cancer patients with depression tended to be high (HR=3.34, 95% CI=1.23-5.49) and a significant trend was found (P<0.05). Conclusion: The data obtained in this prospective study in Chinese support the hypothesis that depression is associated with poor survival among gastric cancer patients. Further studies with a large sample and longer term follow-up period are needed.

  • Background: The aim of the meta-analysis was to derive a more precise assessment of the association between p16 promoter methylation and thyroid cancer risk. Materials and Methods: The PubMed, Web of Science databases and Chinese CNKI were searched for relevant articles. Ultimately, seventeen case-control studies were included with a total of 804 thyroid cancer cases and 487 controls analysis by R Software (R version 3.1.2) including meta. Crude odds ratios with 95% confidence intervals were calculated using the random-effects model which were used to assess the strength of relationship between p16 methylation and lung carcinogenesis. Funnel plots were carried out to evaluate publication bias. Results: The meta-analysis results showed that the frequency of p16 promoter methylation in cancer tissue/blood was significantly higher than that normal tissue/blood (OR=5.46, 95%CI 3.12-9.55, P<0.0001) by random effects model with small heterogeneity. Conclusions: Thus, p16 promoter methylation may be associated with thyroid cancer risk.

  • A survey of mushrooms was conducted in Xishuangbanna, Yunnan Province, China, in the rainy season (May to October) of 2012, 2013, and 2014, during which 16 specimens of Termitomyces were collected. Preliminary macro- and micro-characteristics, together with ITS sequence data, showed that four of the specimens belonged to a new species (Termitomyces fragilis), while the other 12 belonged to T. aurantiacus, T. eurrhizus, T. globules, T. microcarpus, and T. bulborhizus. In this paper, T. fragilis is introduced as a species new to science based on morphological characterization and phylogenetic analyses. Macro- and micro- morphological descriptions, color photographs and line drawings of the new species, and a phylogenetic tree to show the placement of the new species are provided. T. fragilis is then compared with other closely related taxa in the genus Termitomyces.

  • Two new species of the lichen genus Placolecis are discovered in China, namely P. kunmingensis An. C. Yin & Li S. Wang and P. sublaevis An. C. Yin & Li S. Wang. The new combination P. loekoesiana (S.Y. Kondr., Farkas, J.J. Woo & Hur) An. C. Yin is proposed. Placolecis kunmingensis is characterized by having simple, spherical or ellipsoid, hyaline spores, and pear-shaped pycnidia; while P. sublaevis can be distinguished by its thallus forming larger aggregations with slightly flattened lobes at the thallus margin, and urn-shaped pycnidia. Descriptions, a phylogenetic tree and a key are provided for all the known Placolecis species in China.
