    Abstract AbstractCaridina stellata sp. nov. is described from streams in Guangxi, south-western China. The new species clearly belongs to “Caridina serrata group” of the genus and shows a morphological similarity with C. cantonensis Yu, 1938, C. serrata Stimpson, 1860 and C. pacboDo et al. 2020. Caridina stellata is distinguished from congeners, based on differences in its male first pleopod and appendix masculina morphology, along with COI and 16S rRNA molecular evidence. The first pleopod endopod in male is rectangle, about 0.70 × length of exopod, about 3.7–3.9 × as long as proximally wide, inner margin concave, bearing nearly equal spine setae, outer margin bearing nearly equal long and dense spine setae; appendix interna well developed, arising from distal 1/5 of endopod, reaching to end of endopod, with cincinuli distally. The new species displays a unique and brightly coloured pattern and, therefore, can be easily recognised in the field. Liang & Zhou, 1993 described C. cavernicola from the Lenggu Cave, Du’an County, Guangxi. However, the description was based exclusively on two females. We have collected specimens of both sexes near the type locality and describe herein the previously unknown male and present morphological data on females. Data on the habitat, ecology and levels of threat of the two species are provided and suggest that they should be categorised as vulnerable (VU) under the current IUCN Criteria.

    Abstract The commercial value of green raisins produced by the shade-air drying in Liang-fang was 2–3 times as high as that of yellow-brown raisins. This study systematically evaluated the effect of the temperature, humidity, and light of sun drying and shade-air drying on raisins. The sugar, acids, texture and color parament of raisins were compared with different drying conditions. The results indicated that shade-air drying can offer a dark and conducive light environment with the maximum temperature below 40 °C, and a lower humidity by segregating rainwater during the day as well. Then, the contents of acids of raisins in sun drying were lower compared with the shade-air drying and had a lower hardness and a* values of raisins. In summary, low light and ultraviolet intensity, suitable temperature and appropriate humidity environments were the basal and key factors for the formation of the green raisins. The present study not only revealed the crucial factors during shade-air drying in Liang-fang in Turpan, but also provided a scientific basis for improving the Liang-fang conditions and producing green raisins in other regions.

    Abstract Aim: To investigate the synergistic effects of 3'-azido-3'-deoxythymidine (AZT) and FA-2-b-beta extracted from Ling Jin mushroom on apoptosis of gastric cancer cells MKN45 in vitro.
    Methods: MTT analysis was made to examine the inhibition rate of MKN45 cells treated with AZT (2.5, 5, 10 and 20 mg/L) and FA-2-b-beta (5, 10, 20 and 40 mg/L) singly and combinatively for 24, 48 and 72 h. Apoptotic effects were evaluated by morphological methods, DNA agarose gel electrophoresis and flow cytometry, respectively. Telomerase activity was estimated by TRAP-ELISA. The mRNA expression of caspase-3 and Bcl-2 were detected by RT-PCR.
    Results: AZT and FA-2-b-beta could significantly inhibit MKN45 cell proliferation and induce its apoptosis. MKN45 cells were inhibited in dose- and time- dependent manner. The inhibition effect of AZT combined with FA-2-b-beta was obviously better than that used singly (0.469 +/- 0.022 vs 1.075 +/- 0.055, P < 0.05, 0.325 +/- 0.029 vs 0.469 +/- 0.022 P < 0.01). AZT used singly and combination of FA-2-b-beta could decrease the activity of tumor cell telomerase, and AZT has synergistic function with FA-2-b-beta. A certain concentration of AZT could up-regulate the expression of caspase-3 mRNA (r = 0.9969, P < 0.01), which was positively related to apoptosis rate, and could down-regulate the expression of Bcl-2 mRNA, which was negatively related to apoptosis rate (r = 0.926, P < 0.01). Furthermore, the effect of AZT combined with FA-2-b-beta was significantly higher than that used singly.
    Conclusion: Combination of AZT and FA-2-b-beta has an obviously synergetic effect in the gastric cancer cells MKN45, which has provided a new approach to the treatment of gastric cancer clinically.

    Abstract As early as 1930's, Mr. Liang Shuming established a sanitation hospital in the county experimental construction area of Zouping, Shandong province and designed a three-tier model for rural health care. He also explored the way of establishing the health care for rural maternity and children's school hygiene, public health care and itinerant medical care. All of these exert profound influence which is still active and feasible even today.
