【目的】应用光学相干断层扫描血管成像（OCTA）技术定量分析中心性浆液性脉络膜视网膜病变 （CSC）视网膜脉络膜的微循环变化。【方法】经常规眼科临床检查，眼底荧光血管造影（FFA）、吲哚菁绿血管造 影（ICGA）等方法确诊CSC 患者61 例67 眼。选取年龄、屈光匹配的正常人15 名、30 眼作为正常对照组。对 OCTA 检测结果进行比较，分析CSC 患者视网膜脉络膜微循环的特点。【结果】CSC 患眼视网膜表层血流密度 （VDSR）和视网膜深层血流密度（VDDR）均低于正常眼，但差异无显著性意义（P = 0.325，P = 0.056）。CSC患眼 脉络膜浅层血流密度（VDSC）明显低于正常对照组，差异有显著性意义（P＜0.001）。经亚组分析，慢性CSC组中 VDSR、VDDR均显著低于正常对照组（P = 0.042，P = 0.037），而急性CSC组中VDSR、VDDR与正常对照组无显著 性差异。【结论】本研究发现CSC患眼存在眼底微循环异常，脉络膜浅层血流密度低于正常眼，并首次发现了慢 性CSC视网膜表层和深层毛细血管血流密度低于正常眼，提示病史较长的患眼微循环异常不仅累及脉络膜血管 而且累及视网膜血管。

Objective To investigate the effect of Liu-Shen-Wan on transplanted tumors in mice with colon cancer based on the polarization of M2 macrophages in the tumor microenvironment. Methods We established a subcutaneous transplantation tumor model of mice with CT26 colon cancer. Mice were randomly divided into vehicle, oxaliplatin, and oxaliplatin combined with Liu-Shen-Wan groups. Treatment was administered for three weeks, and tumor volume was measured. All mice were weighed during the administration. After the end of the treatment, the mice were dissected and tumors were photographed and weighed. Spleen index was calculated. The expression levels of IFN-γ and IL-12P40 in serum and related blood biochemical indices were measured. The expression levels of M2 macrophage polarization indices, namely, IL-10 and TGF-β, in serum and tumor tissues were detected. The infiltration degree of M2 macrophages in each group was observed by immunohistochemical experiments. Results The tumor volume and mouse weight in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased compared with those in the vehicle group. The spleen index increased, and the expression levels of IFN-γ and IL12P40 in serum also significantly increased. The mice had no obvious side effects after the drug treatment. In addition, the expression levels of IL-10 and TGF-β in the serum and tissues of mice in the oxaliplatin combined with Liu-Shen-Wan group significantly decreased. The expression levels of CD68 and CD206 in tumor tissues also decreased. Conclusion The anti-tumor effect of Liu-Shen-Wan on the transplanted tumors of mice with colon cancer is related to the inhibition of M2 macrophage polarization in the tumor microenvironment.

In order to explore the pollination biology characteristics of Pleione formosana Hayata, their flowering phenology, pollen vigor, stigma receptivity, breeding systems, and insect pollination behaviors were observed for 2 consecutive years in the Daiyunshan National Nature Reserve in Fujian. It was found that Bombus trifasciatus and Bombioxylocopa chinensis are the pollinators of P. formosana. The thorax heights of Bombus trifasciatus and Bombioxylocopa chinensis were (1.4±0.2) cm and (1.5±0.2) cm, respectively, both of which were higher than the height of the pollination channel entrance by (0.8±0.2) cm. The pollinating insect enters the flower through the mid-lobe of the outer bending lip. When it finds no nectar as reward, it exits the flower; the anther cap will then open causing the viscidium of the pollinium to adhere to the back of the pollinator. When the pollinator enters the same flower or different flowers, the pollination may be completed. It is speculated that P. formosana may attract insects through its golden yellow stripes (fake nectar-guide) on its lips for pollination, which is food-deceptive. Breeding experiments showed that P. formosana is highly self-compatible and that there is no apomixis or self-pollination. The pollination success of this species depends on its pollinators. Therefore, the population density of pollinators and their frequency of visiting flowers may be important factors affecting the fruit set of P. formosana, and ultimately affect the maintenance and expansion of its population.
