糖尿病已成为全球最严重的健康问题之一。需要白内障手术的糖尿病患者也日益增多,虽然糖尿病的眼表并发症很常见,但由于糖尿病患者全身和眼部疾病十分复杂,使得眼前段如角结膜和泪腺的糖尿病并发症往往被忽视。糖尿病患者白内障超声乳化术有引发或加重眼前节疾病的风险,包括干眼病（DED）、角膜上皮糜烂、上皮缺损迁延不愈,甚至威胁视力的角膜溃疡。这些风险里最为常见的是DED,并且可能因白内障超声乳化手术而加重。眼科医生需要在手术前预先评估已存在的DED是否需要术前治疗,并且需要注意在已存在 DED 的情况下,各项术前检查数据测量的准确性会降低,以及尽可能减少对眼表造成损害的各种手术因素;并考虑通过管理减少术后 DED。本综述就评估白内障超声乳化术对合并糖尿病的老年性白内障患者的眼表术中的影响因素进行分析。

Diabetes mellitus(DM)has become one of the most serious health problems in the world. The number of diabetic patients requiring cataract surgery is also increasing. Although ocular surface complications of DM are common,the complexity of systemic and ocular disease in diabetic patients makes diabetic complications in the anterior segment,such as the cornea and lacrimal gland,often be overlooked. Phacoemulsification in diabetic patients carries the risk of triggering or exacerbating ocular segment disease,including dry eye disease,corneal epithelial erosion,persistent epithelial defects and even vision-threatening corneal ulcers. The most common of these risks is dry eye disease,and it can be exacerbated by cataract phacoemulsification. Ophthalmologists need to preemptively assess the need for preoperative treatment of pre-existing dry eye disease(DED),be aware of the reduced accuracy of preoperative data measurements in the presence of DED,and minimize surgical factors that can damage the ocular surface;and consider management to reduce postoperative DED. In this review,we analyze the factors that influence phacoemulsification in ocular surface surgery for senile cataract patients with diabetes.

严重烧伤后患者免疫功能的失调,易导致创面感染、全身炎症反应综合征、脓毒症、感染性休克等并发症,增加患者病死率。免疫细胞功能适度的活化将有助于烧伤患者抵御外界病原体的侵袭、促进创面的愈合,但功能过度激活或者功能低下,则会引发一系列严重的后果。本文旨在归纳严重烧伤后中性粒细胞、单核/巨噬细胞、肥大细胞、NK细胞及T淋巴细胞等免疫细胞的功能变化与炎症反应之间的关系,为完善烧伤患者诊疗、减少并发症、改善预后提供新的思路。

The imbalance of immune function in severely burned patients can easily lead to wound infection,systemic inflammatory response syndrome,sepsis,septic shock and other complications,which increase the mortality of patients. Moderate activation of immune cell function will help burned patients to resist the invasion of external pathogens and promote wound healing,but excessive activation or low function can lead to a series of serious consequences. The purpose of this paper is to summarize the relationship between the functional changes of immune cells such as neutrophils,monocytes/macrophages,mast cells,NK cells,T lymphocytes and inflammatory reaction after severe burns,and to provide new ideas for improving the diagnosis and treatment of burned patients,reducing complications and improving the prognosis.

Objective To understand the current situation and main influencing factors of career decision-making difficulties of higher vocational medical students, and put forward improvement countermeasures. Methods The method of stratified cluster sampling was adopted, with 740 full-time medical students from a vocational college in Guangzhou being investigated. Results The average score of career decision-making difficulty of medical students surveyed in higher vocational colleges was (3.55±0.647), in which the average score of the career planning exploration was the lowest (3.42±0.797), and the average scores of other dimensions from low to high were career goal exploration (3.49±0.766), career information exploration (3.58±0.678) and career self-exploration (3.69±0.659). The results of one-way analysis of variance (ANOVA) showed that there were significant differences in the scores of career decision-making difficulties of medical students in higher vocational colleges among different majors, the major being the first choice or not, and different living places (P<0.05). The results of multiple stepwise regression analysis showed that family location, school guidance courses for career planning, part-time or trainee experience, school activities (employment guidance lectures, career planning competitions, etc.), being optimistic about the employment prospects of their majors, schools providing sufficient employment information, and having participated in innovation and entrepreneurship competitions were predictors of difficulties in career decision-making for medical students (P<0.05). Conclusions The difficulty of career decision-making of medical students in higher vocational colleges was in the middle level. Schools can establish a systematic evaluation and intervention system aiming at career decision-making difficulties by carrying out targeted career guidance, and build practice and employment service platform to improve the career decision-making difficulties of medical students in higher vocational colleges, and to provide strong support and security for students. The government can enhance policy guidance for medical students in higher vocational colleges to apply for primary hospital.

Objective To analyze the effect of the “Birthday Blood Donation Medal” (hereinafter referred to as the Birthday Medal) personalized souvenir to the blood donor recruitment and retention effect of blood donors in Guangzhou Blood Center. Methods From 2017 to 2019, there were a total of 11 790 blood donors donated blood on their birthday in Guangzhou Blood Center. Aline chart was drawn of the number of blood donors who donated blood on birthday to observe the trends every half a year from 2017 to 2019; Chi-square test was used to compare the characteristics of blood donors in two groups (before and after the “Birthday Blood Donation Medal” activity) and we analyzed the sensitive population of the activity. Results The number of blood donors on the birthday every half year from 2017 to 2019 continued to increase. Among them, the number of blood donors donated on birthday on July-December 2018 increased by 406% compared to the first six months of 2018, which was the largest increase. The differences in gender, age, occupation, and previous blood donation times between the two groups were statistically significant (P<0.05). After the activity, the percentage of male, 35-year-old and above blood donors, workers/clerks and other occupations, and regular blood donors increased. Conclusion The “Birthday Blood Donation Medal” activity in Guangzhou Blood Center has a significant promotion effect on blood donation on birthday. Among them, males, aged 35 and above, workers/occupations/other occupations and regular blood donors are more sensitive to this activity and are more likely to donate blood on birthday. In the future, other recruitment and retention measures should be taken to pay attention to women, under 25 years old, students and first-time blood donors.

Objective To investigate the clinical values of etiological diagnosis by testing cardiac index CI and total peripheral resistance index TPRI using bioreactance noninvasive cardiac output monitoring NICOM in patients with dyspnea. Methods Prospective,observational study was taken in 113 adult patients admitted with dyspnea or acute exacerbation of dyspnea in stable disease. The patients were divided into two groups namely heart failure group （n=55）and non-heart failure group（n=58） according to the guidelines on the diagnosis and treatment of acute heart failure（2010） as the standard criterion. All patients underwent CI and TPRI test by using NICOM. Receiver operating characteristic curve（ROC curve） was plotted to evaluate the diagnostic value of CI and TPRI. Results Compared with non-heart failure group,the CI was worse（P<0.001）,and the TPRI was elevated（P<0.001）. ROC curve showed that the area under the curve（AUC） of CI was 0.792（95%CI：0.708~0.875,P=0.000）. The cut-off of CI was 2.65L/min/m²,the sensitivity was 63.6%,and specificity was 87.9%. The AUC of TPRI was 0.733（95%CI：0.641~0.825,P=0.000）. The cut-off of CI was 2 353dynes.sec/cm⁵/m²,the sensitivity was 72.7%,and specificity was 67.2%. The sensitivity of CI combined TPRI was 80%,and specificity was 65.5%. Conclusion NICOM monitoring CI have high specificity,and combined TPRI monitored may improve sensitivity for dyspnea caused by heart failure.
