RÉSUMÉ
Ethnic medicine is an important part of traditional Chinese medicine, which has encountered many problems in the development process, such as the lack of effective inheritance of valuable experience and practice, weak basic research and lack of talents, serious destruction of ethnic medicine resources, uneven quality of medicinal materials, weak intellectual property protection, etc. To sum up, these seriously restrict the development of ethnic medicine. Here, the authors propose some corresponding suggestions according to these problems. Firstly, we should try our best to protect and mine relevant professional books for promoting national medicine culture, establish complete system of national and local standards, strengthen the construction of standardized planting bases and germplasm resource banks, build a well-known brand of ethnic medicine and give full play to the leading role of the brand. Secondly, we should strengthen basic research on ethnic medicine and build an integrated system of production-study-research. By integrating the strength of culture, scientific research, talents and industry, this paper hopes to promote the vigorous development of ethnic medicine.

Appropriate producing areas can guarantee the quality of Tibetan medicine, but research on the suitable ecological factors and suitable producing areas of Tibetan medicinal plants is scarce. This paper used the Geographic Information System for Global Medicinal Plants(GMPGIS) to analyze the ecological suitability of Tibetan medicinal plants nationwide. For the first time, the range of ecological factors and main soil types of Tibetan medicinal plants were extracted, such as the average annual temperature-19.4-24.2 ℃, annual average precipitation 17-4 088 mm, annual average sunshine 124.2-171.6 W·m~(-2). The main soil types were black calcareous soil, thin layer soil, chestnut soil and so on. Based on 337 sampling points, the largest ecological similarity area of Tibetan medicine across the country was obtained through ecological similarity analysis. In addition to Tibet and Qinghai provinces and Tibetan Autonomous Prefectures in Sichuan, Gansu, and Yunnan provinces, Jiuquan city and Linxia county in Gansu province, Panzhihua and Ya'an in Sichuan province, and Xinjiang, Inner Mongolia, and Shanxi provinces also had larger suitable cultivation areas. In addition, by analyzing the current situation of Tibetan medicine industry, the research pointed out that there were some problems such as unreasonable development and utilization of resources, lack of standards and norms, weak basic research and imperfect industrial system, and made corresponding countermeasures for sustainable development of resources, formulation of standards and specifications, promotion of medicine through science and technology, expansion of domestic and foreign markets, etc. This study provided the basis for guiding the rational layout of production bases, introduction and breeding of plant Tibetan medicine nationwide, laying the foundation for the scientific and standardized production of high-quality Tibetan medicine, clarifying the development direction of Tibetan medicine industry, and providing ideas for the development strategy of Tibetan medicine and other national medicine industry.

To build a well-off society in an all-round way, eliminate poverty, improve people's livelihood and improve the level of social and economic development in poverty-stricken areas is the frontier issues of the government and science and technology workers at all levels. Chinese herbal medicine is the strategic resource of the people's livelihood, Chinese herbal medicine cultivation is an important part of China's rural poor population income. As most of the production of Chinese herbal medicine by the biological characteristics of their own and the interaction of natural ecological environment factors, showing a strong regional character.the Ministry of Traditional Chinese Medicine and the State Council Poverty Alleviation Office and other five departments jointly issued the "China Herbal Industry Poverty Alleviation Action Plan (2017-2020)", according to local conditions of guidance and planning of Chinese herbal medicine production practice, promote Chinese herbal medicine industry poverty alleviation related work In this paper, based on the relevant data of poverty-stricken areas, this paper divides the areas with priority to the poverty alleviation conditions of Chinese herbal medicine industry, and analyzes and catalogs the list of Chinese herbal medicines grown in poverty-stricken areas at the macro level. The results show that there are at least 10% of the poor counties in the counties where the poverty-stricken counties and the concentrated areas are concentrated in the poverty-stricken areas. There is already a good base of Chinese herbal medicine industry, which is the key priority area for poverty alleviation of Chinese herbal medicine industry. Poverty-stricken counties, with a certain degree of development of Chinese medicine industry poverty alleviation conditions, the need to strengthen the relevant work to expand the foundation and capacity of Chinese herbal medicine industry poverty alleviation; 37% of poor counties to develop Chinese medicine industry, the basic conditions of poverty alleviation. It is suggested that: prioritized priorities, counties that have a good foundation for Chinese herbal medicine industry will implement the "Poverty Alleviation Action Plan for Chinese Herbal Medicine Industry" through nearly 100 counties with priority development.
RÉSUMÉ
<p><b>OBJECTIVE</b>To analyze the characteristics of complex chromosomal rearrangement (CCR) in Chinese male carriers and its influence on male fertility.</p><p><b>METHODS</b>Using the G band technique, we conducted karyotype analysis on the peripheral blood lymphocytes of 1,625 Chinese males with reproductive problems. We also searched CNKI and Wanfang database for CCR-related literature published between January 1984 and November 2013, followed by statistical analysis on the CCR characteristics and reproduction-related data of the CCR carriers.</p><p><b>RESULTS</b>Two CCR carriers were found among the 1,625 males and another 47 cases identified from the databases. Among the 49 CCR carriers, there were 17 three-way exchange cases (34.7%), 17 double two-way exchange cases (34.7%), and 15 exceptional cases (30.6%), with no statistically significant differences in the incidence of the three types (P > 0.05). Azoospermia- or oligospermia-induced infertility was found in 19 (38.8% ) of the CCR carriers. A total of 87 pregnancies were achieved in the other 30 (61.2%), among which spontaneous abortion occurred in 75.9% (66/87), dead fetus and malformed infant death in 9.2% (8/87), and phenotypically normal offspring in 14.9% (13/87). Recurrent abortion was associated frequently with breakpoints on CCR-involved chromosomes 6, 7, 8, 11, and 16, while dyszoospermia mostly with breakpoints on CCR-involved chromosomes 10 and 14. The breaking occurred more than 3 times at 1p22, 1q25, 2q31, 5p13, 5q35, 6q23, 8q13, and 20p13. Moreo- ver, the breakpoints at 2q31, 5q35, and 8q13 were particularly related to recurrent abortion, while that at 1p22 only to dyszoospermia.</p><p><b>CONCLUSION</b>CCR is extremely rare. Male CCR carriers are often identified through reproductive problems and have high risks of infertility and abnormal pregnancy and a very low rate of normal newborns. In addition, chromosomes and breakpoints involved in CCR may affect the fertility of male CCR carriers, and some particular chromosomal breakpoints may play a key role in gametogenesis.</p>

<p><b>OBJECTIVE</b>To approach the relationship between the expression of hK6 in ovarian neoplasm and clinicopathological variables and prognosis in ovarian cancer patients for finding a new tumor marker of the ovarian cancer.</p><p><b>METHODS</b>The expression of hK6 was detected by immunohistochemistry in 19 cases of benign, 11 cases of borderline and 45 cases of malignant ovarian neoplasms and statistically analyzed whether its expression correlate with clinicopathological variables and prognosis in patients with ovarian cancer.</p><p><b>RESULTS</b>The expression of hK6 in ovarian cancer tissues (60.0%) was significantly higher than that in the benign (15.8%) and borderline (27.3%) ovarian neoplasm tissues (P < 0.01). The expression of hK6 in higher-grade ovarian cancer tissues (68.4% ) was higher than that in low-grade ones (14.3%, P < 0.05). The expression of hK6 in late-stage (stage III, 76.7%) was significantly higher than that in early-stage (stage I or II, 26.7%, P < 0.01). The expression of hK6 was significantly higher in patients with lymph node metastasis (77.8%) than that in patients without (33.3%, P < 0.01). The expression of hK6 in the cancer tissues in the patients died, or with reccurence or metastasis within 3 years after surgery was higher (75.0%) than that in the patients with stable disease (42.9%, P < 0.05).</p><p><b>CONCLUSION</b>The expression of hK6 in ovarian cancer was higher than that in benign and borderline ovarian neoplasms. The expression of hK6 is higher in the ovarian cancer of late stage, higher-grade, with lymph node metastasis and is associated with a poorer prognosis. hK6 may become a new markers in prediction of prognosis of the patients with ovarian tumors.</p>

<p><b>OBJECTIVE</b>To formulate recommendations in the evaluation of results of genetic analyses in paternity testing under considering mutations.</p><p><b>METHODS</b>A total of 15 short tandem repeat(STR) loci were employed for this study, which were included CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, PentaD and PentaE. Both 100 cases of true trio and 100 cases of false trio were investigated.</p><p><b>RESULTS</b>The numbers of mismatch alleles in different STR loci were observed in 100 cases of false trio. The different distributions of paternity index were obtained, including the changes of paternity index in each case of true trio under simulated mutations.</p><p><b>CONCLUSION</b>In order to avoid the effect of mutations, the exclusion of paternity was never considered on the basis of a single locus. The threshold values of the combined probability of exclusion and the paternity index were important for both exclusion and inclusion of paternity. The scientific evidence for paternity testing can be obtained when both the combined probability of exclusion and the paternity index meet the threshold values. However, when either the combined probability of exclusion or the paternity index can not meet the threshold values, more genetic markers should be added.</p>
