：【目的】分析新诊断2型糖尿病患者的糖尿病视网膜病变（DR）与糖尿病周围神经病变（DPN）的发病特点及其 相关危险因素与2种微血管病变之间的关联性。【方法】回顾性分析2009-2012年期间新诊断的共211例2型糖尿病患者的 住院资料，并对DR与DPN进行患病特点、发病危险因素与2种微血管病变的关联性的分析。【结果】新诊断2型糖尿病的患 者中DPN的患病率（33.6%）高于DR（12.3%），2种微血管病变可共同存在，且DR与DPN存在关联（r = 0.158，P = 0.020）。单 因素分析显示年龄、收缩压为2种微血管病变的共同相关危险因素。【结论】在新诊断2型糖尿病时，在各年龄段均应注意 同时筛查DR与DPN，在控制血糖的同时，控制收缩压将有利于DR与DPN的共同防治。

设置临时支撑几乎是所有大跨度空间钢结构施工过程中必然要遇到的问题。由于临时支撑的存在,改善了结构的受力性能,使结构更加安全,但是辅助用钢量也会增加较多。在符合受力的前提下,如何实现建造过程中安全和经济的平衡是施工研究的关键。以世界大学生运动会主体育场实际工程为例,对结构进行临时支撑提前卸载分析,并将计算结果同未提前卸载的分析结果进行比较,给出了结构内力和变形的变化趋势,提出了有针对性的改进意见。分析计算结果表明:直接循环卸载方案不安全因素较大,而考虑关键位置修正的循环卸载方案可以运用于大跨度空间结构的施工中,为大跨度空间结构合理施工提供参考。

【目的】初步评价眼内窥镜下激光睫状体光凝术(endoscopic cyclophotocoagulation，ECP)在治疗人工晶体植入术后继发青光眼中的疗效。【方法】采用Endo Optiks，URAM E2激光内窥镜系统对21例21眼人工晶体植入术后继发青光眼进行了ECP治疗，观察术后眼压变化、视力以及并发症情况，术后分别随访了6～26个月，平均18.7个月。【结果】21只眼术前眼压平均(5.08±1.69)kPa，术后平均眼压(1.96±1.23)kPa，术前、术后眼压差异有统计学意义(P＜0.001)。术前平均使用降眼压药物3.3种，术后下降到0.6种，差异有统计学意义(P＜0.001)。术后无需应用药物治疗而眼压≤2.8 kPa者占71.4％，需要应用局部药物治疗控制眼压≤2.8 kPa者占14.3％。患者术后视力较术前有增高(P＜0.05)。21只眼中有1只眼术后出现前房积血，有19只眼术后瞳孔区出现纤维素样渗出，1只眼术后发生渗出性脉络膜脱离。这些并发症出现在早期，井在1周内愈合。所有患者术后均未出现视网膜脱离、眼压过低、眼内炎、交感性眼炎等并发症。【结论】ECP能有效地降低人工晶体植入术后继发青光眼的眼压，无严重并发症。ECP是一种治疗人工晶体植人术后继发青光眼的安全有效的方法。

[Objective] The aims of this study are to explore the spatial and temporal distribution characteristics and seasonal change patterns of precipitation of various grades across China, enhance the knowledge of the occurrence patterns of different grades of precipitation in China, and then provide scientific and technological support for enhancing the national disaster prevention and mitigation capacity. [Methods] Based on the daily surface precipitation data from 681 meteorological stations in China during 1961—2020, the temporal and spatial distribution characteristics and seasonal variation of the days and intensity of precipitation of different grades (light rain, moderate rain, large rain and heavy rain) across China were analyzes. [Results] (1) From 1961 to 2020, the number of light rain days showed a decreasing trend, while the number of moderate rain, large rain and heavy rain days showed an increasing trend, and no significant changes in the intensity of light, moderate and large rain except for great changes in the intensity of heavy rain were found. The number of light rain days decreased the most in autumn, large and heavy rain days increased the fastest in summer, and the slowest in autumn. The intensity of heavy rain fluctuated greatly in each season. (2) There was some variability in the spatial distribution of different precipitation levels, the high number of light rain days mainly distributed in the southwest river basins, the number of days with moderate rain and above and the intensity of precipitation at each level gradually decreased from southeast to northwest, and the number of days and intensity of precipitation in the Inland River basins were the smallest. (3) Precipitation in spring, autumn and winter mainly concentrated in the southeastern River Basins and the Pearl River Basin, where light rainfall predominated, and in summer precipitation mainly concentrated in the southwestern Rivers Basin, the southeastern Rivers Basin and the Pearl River Basin. The areas with higher intensity of precipitation at all levels in spring were mainly located in the southeastern Rivers Basin, the Yangtze River Basin and the Pearl River Basin, and the areas with higher intensity of precipitation in winter were mainly located in the southeastern Rivers Basin and the Huaihe River Basin. (4) The decrease in the number of light rain days was more obvious in spring and winter, and the southeastern River Basins and the Pearl River Basin contributed greatly to the decrease in the number of light rain days. The number of precipitation days above the moderate rain level was generally on an upward trend in all seasons. The intensity of large rain strengthens in spring and weakened in autumn, and the intensity of heavy rain in all basins was on an increasing trend in spring. [Conclusion] There are obvious differences in the spatial and temporal distribution and seasonal scales of precipitation levels across China, and the contribution of the nine major river basins to the different levels of precipitation across the China varies, so future research on the influence of the major circulation systems and the water cycle in each river basin on the different levels of precipitation should be strengthened.

In order to investigate the deposition characteristics of spray particles after impacting the substrate during activated combustion-high velocity air fuel (AC-HVAF) thermal spraying process. WC-10Co-4Cr coatings were deposited on AZ80 magnesium alloy substrate by AC-HVAF thermal spraying technology. Thin layer of deposited particles were obtained by discrete deposition experiments. Types of various morphologies after deposition, formation reasons, binding mechanisms and radial and axial distributions of particles in the jet were discussed. The results show that in the process of AC-HVAF particle deposition, the embedded deposition is the main deposition morphology, and contains a small amount of broken and hollow deposition particles. In the formation process of the coating, the embedded deposition plays an important role in the bonding performance of the coating-substrate. The small cavity type deposition particle and the large broken type deposition particle are the main reasons for the decline of deposition efficiency. The spray particles are mainly concentrated in the jet center, and the closer to the jet edge, the more cavity type particles are deposited, which ultimately leads to the spatial distribution characteristics of AC-HVAF particle jet.

Malignant tumors are major diseases that threaten human health. The development of safe and efficient antitumor drugs and their delivery systems is an important guarantee for improving the efficacy of antitumor drugs. In recent years, cyclodextrin-based antitumor drug host-guest delivery systems have received much attention. Cyclodextrins are cyclic oligosaccharides obtained by amylolytic enzymes with an external hydrophilic internal hydrophobic structure, and have been widely used in gene therapy, immune cell therapy, immune-targeted therapy, and chemotherapy. This review summarizes the advances related to cyclodextrins as antitumor drug delivery carriers, and also provides a perspective and discussion on the opportunities and challenges of host-guest delivery systems in oncology therapy.

Objective To explore the clinical effect of acupoint sticking therapy on postoperative nausea and vomiting (PONV) after gynecological laparoscopic surgery. Methods From January 2020 to April 2021, 60 inpatients who underwent laparoscopic surgery for the first time in the department of gynecology of the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine were selected and randomly divided into control group (30 cases) and observation group (30 cases). The control group was given routine treatment, while the observation group was given acupoint application on the basis of the control group. The incidence of PONV and other adverse reactions after operation were compared between the two groups. Results There were statistically significant differences between the two groups in the incidences of PONV 0-24 h and 24-72 h after operation (P <0.05). There were statistically significant differences between the two groups in the incidence of postoperative abdominal pain and other adverse reactions (P <0.05). Conclusion Acupoint sticking therapy can effectively relieve PONV symptoms after gynecological laparoscopic surgery and reduce the incidence of other adverse reactions. [ABSTRACT FROM AUTHOR]
