乳腺癌根治术患者术前焦虑的影响因素分析及其对术后恢复、细胞免疫功能和生命质量的影响

摘要 目的：分析乳腺癌根治术患者术前焦虑的影响因素,并探讨术前焦虑对患者术后恢复、细胞免疫功能和生命质量的影响。方法：选择我院2020年3月~2021年12月期间收治的拟行乳腺癌根治术的120例患者作为研究对象,术前1 d采用焦虑自评量表（SAS）评估所有患者的焦虑状况,根据是否存在焦虑分为焦虑组和无焦虑组,乳腺癌根治术患者术前焦虑的影响因素采用多因素Logistic回归分析。对比焦虑组和无焦虑组的术后恢复、细胞免疫功能和生命质量情况。结果：120例乳腺癌根治术患者中,有31例患者无术前焦虑,89例患者存在焦虑症状,根据是否存在术前焦虑分为焦虑组（n=89）和无焦虑组（n=31）。乳腺癌根治术患者术前焦虑与年龄、文化程度、家庭人均月收入、付费方式、婚姻状况、家庭支持、既往有无全麻史、术前住院时长、定期体检有关（P<0.05）。多因素Logistic回归分析结果表明：年龄＜60岁、文化程度为小学及其以下、家庭人均月收入＜3000元、婚姻状况为未婚、无家庭支持、既往无全麻史、术前住院时长>1 d是乳腺癌根治术患者术前焦虑的危险因素（P<0.05）。焦虑组的术后首次肛门排气时间、首次下床活动时间、术后住院时间均长于无焦虑组（P<0.05）。两组术后1个月CD3⁺、CD4⁺、CD4⁺/CD8⁺水平升高,且无焦虑组高于焦虑组（P<0.05）,两组术后1个月CD8⁺水平下降,且无焦虑组低于焦虑组（P<0.05）。两组术后1个月生理状况、情感状况、社会/家庭状况、功能状况、附加关注评分和总分下降,且无焦虑组低于焦虑组（P<0.05）。结论：乳腺癌根治术患者术前焦虑发生率较高,其发生受到年龄、文化程度、家庭人均月收入、婚姻状况、家庭支持、既往有无全麻史、术前住院时长等多种因素的影响,可导致患者术后恢复时间延长,细胞免疫功能和生命质量降低。

CULTURE STUDIES ON THE RELATIONSHIP BETWEEN SCHIZYMENIA AND HAEMATOCELIS (GIGARTINALES,RHODOPHYCEAE) FROM THE PACIFIC COAST OF NORTH AMERICA1

Carpospores from Schizymenia pacifica (Kylin) Kylin (Gymnophlaeaceae) from California formed crusts anatomically identical to Haematocelis rubens J. Agardh (Cruoriaceae). Tetraspores of H. rubens from Monterey, California, and Baja California, Mexico, germinated to form basal discs from which arose upright multiaxial blades with a filamentous medulla and cortical gland cells. Pro-carps and spermatangia were present on the same blades; subsequently, cystocarps characteristic of Schizymenia pacifica developed. Re-examination of herbarium specimens suggests that the foliose tetrasporangial phases previously reported as S. pacifica are referable to Halymenia, Dilsea, Cryptonemia, or Turnerella. Schizymenia pacifica (type locality: San Juan Islands, Washington) thus is considered to be the gametophyte in the life history of Haematocelis rubens (type locality: Brest, France), which has also been reported to be the tetrasporophyte of S. dubyi (Chauvin ex Duby) J. Agardh (type locality: Cherbourg, France). Atlantic and Pacific gametophytes and tetrasporophytes are anatomically very similar, suggesting that only one species is involved, but critical studies must be made before a decision on this taxonomic question can be reached. Haematocelis zonalis Dawson et Neushul (type locality: Anacapa Island, California) is considered to be a growth form of the tetrasporangial phase of S. pacifica.     

DISTINCTION OF SOUTH AMERICAN HAPLOGLOIA ANDERSONII AND CHORDARIA LINEARIS (PHAEOPHYCEAE) BASED ON DIFFERENCES IN SEXUAL REPRODUCTION,MORPHOLOGY, ECOPHYSIOLOGY,AND DISTRIBUTION1

Haplogloia andersonii (Farlow) Levring is an anti-tropical species that occurs on cold and warm-temperate Pacific coasts of both Americas. In its habit it resembles the subantarctic species Chordaria linearis (Hooker et Harvey) Cotton. Culture studies show that the species differ in morphology and ecophysiology of their microscopic gametophytes and in gamete behavior. Details of sporophyte anatomy are presented that also allow the distinction of field plants. In South America, H. andersonii occurs only on the Pacific coast, from central Perú (14°S) to southern Chile (50°S). Chordaria linearis occurs on the Pacific coast from Chiloé Island (43°S) to Cape Horn (56°S). In the shared area the species may co-occur. On the Atlantic coast, C. linearis was newly collected at a locality in northern Patagonia (41°S). In addition, C. linearis occurs in Antarctica. Haplogloia moniliformis Richer, recently described from Macquarie Island, is probably synonymous with Chordaria linearis.     

LIFE CYCLE OF A STEPHANODISCUS SP. (BACILLARIOPHYTA)1

Studies of the life cycle of a centric diatom, tentatively identified as Stephanodiscus neoastraea Håkansson & Hickel, showed that sexual reproduction occurred every year in a freshwater lake (Lough Neagh, Northern Ireland). Male and female gametes were produced in cells below 55% of the maximum diameter during a 3–4-week period in late summer, following the return of nitrate concentrations above 10 μM NO_3-N. The frequency of sexual reproduction was linked to the cycle of diameter size reduction and regeneration. The times of largest decreases in cell diameter were during nutrient stress in summer and low light conditions in late autumn, rather than during the main spring growth period. So, environmental conditions (combined with the limited life-spans of individual cells) affected the rate of diameter reduction and, therefore, the length of the life cycle (3–4 years).     

DEVELOPMENTAL MUTANTS OF VOLVOX: DOES MUTATION RECREATE THE PATTERNS OF PHYLOGENETIC DIVERSITY?

The nature of the variation which is created by mutation can show how the direction of evolution is constrained by internal biases arising from development and pre-existing design. We have attempted to quantify these biases by measuring eight life history characters in developmental mutants of Volvox carteri. Most of the mutants in our sample were inferior to the wild type, but deviated by less than tenfold from the wild-type mean. Characters differed in mutability, suggesting different levels of canalisation. Most correlations between life history characters among strains were positive, but there was a significant negative correlation between the size and the number of reproductive cells, suggesting an upper limit to the total quantity of germ produced by individuals. The most extreme phenotypes in our sample were very vigorous, showing that not all mutations of large effect are unconditionally deleterious. We investigated the effect of developmental constraints on the course of evolution by comparing the variance and covariance patterns among mutant strains with those among species in the family Volvocaceae. A close correspondence between patterns at these two levels would suggest that pre-existing design has a strong influence on evolution, while little or no correspondence shows the action of selection. The variance generated by mutation was equal to that generated by speciation in the family Volvocaceae, the genus Volvox, or the section Merillosphaera, depending on the character considered. We found that mutation changes the volume of somatic tissue independently of the quantity of germ tissue, so that the interspecific correlation between soma and germ can be attributed to selection. The negative correlation between size and number of germ cells among mutants of V. carteri is also seen among the larger members of the family (Volvox spp.), but not among the smaller members, suggesting a powerful design constraint that may be responsible for the absence of larger forms in the entire group.
