术后疼痛对膝关节盘状半月板损伤患者膝关节功能、生活质量及心理状态的影响及其危险因素的Logistic回归分析

摘要 目的：探讨术后疼痛对膝关节盘状半月板损伤患者膝关节功能、生活质量及心理状态的影响及其危险因素的Logistic回归分析。方法：选取2019年5月～2022年1月福建医科大学附属第一医院收治的膝关节盘状半月板损伤患者120例,均行关节镜手术治疗,观察并评价所有患者手术疗效;根据术后6个月膝关节是否疼痛分为疼痛组（n=16）与无痛组（n=104）。比较两组术前及术后6个月Lysholm膝关节功能评分、健康调查简表（SF-36）评分、焦虑自评量表（SAS）和抑郁自评量表（SDS）评分。单因素及多因素Logistic回归分析术后疼痛的危险因素。结果：120例膝关节盘状半月板损伤患者术前、术后3个月、术后6个月Lysholm评分分别为（56.97±8.62）分、（78.09±10.53）分、（89.26±8.14）分,术后3个月、术后6个月Lysholm评分均显著高于术前（均P＜0.001）。临床疗效显示行关节镜手术后优良率为86.67%（104/120）。术后6个月两组Lysholm评分、SF-36评分均高于手术前,但疼痛组低于无痛组（P＜0.05）;术后6个月两组SAS评分、SDS评分均低于手术前,但疼痛组高于无痛组（P＜0.05）。单因素分析发现,年龄、BMI、撕裂类型、滑膜切除、术后冷敷、开始负重时间与术后痛疼有关（P＜0.05）;而性别、受教育程度、吸烟史、饮酒史、ASA分级、患侧、病程、损伤部位、手术方式与术后痛疼无关（P＞0.05）。多因素Logistic回归分析显示,年龄、BMI≥24 kg/m²、纵裂或其他撕裂、滑膜切除、开始负重时间＜4周及术后6个月SAS评分、SDS评分是术后疼痛的独立危险因素,而术后冷敷是术后疼痛的保护因素（P＜0.05）。结论：术后疼痛对膝关节盘状半月板损伤患者膝关节功能、生活质量及心理状态产生明显负面影响。年龄、BMI≥24 kg/m²、混合性撕裂、滑膜切除、开始负重时间＜4周以及术后6个月SAS评分、SDS评分是术后疼痛危险因素,而术后冷敷是其保护因素,临床可据此施以针对性防治措施。

Photoregulation of seed germination of wild-type and of an aurea-mutant of tomato

Seed germination of an aurea mutant of tomato ( Lycopersicon esculentum Mill.) is promoted by continuous irradiation with red, far-red or long-wavelength far-red (758 nm) light as well as by cyclic irradiations (5 min red or 5 min far-red/25 min darkness). Far-red light applied immediately after each red does not change the germination behaviour. Seed germination of the isogenic wild-type, cv. UC-105, is promoted by continuous and cyclic red light while it is inhibited by continuous and cyclic far-red light and by continious 758 nm irradiation. Far-red irradiation reverses almost completely the promoting effect of red light. The promoting effect (in the aurea mutant) and the inhibitory effect (in the wild-type) of continuous far-red light do not show photon fluence rate dependency above 20 nmol m⁻² s⁻¹. It is concluded that phytochrome controls tomato seed germination throgh low energy responses in both the wild type and the au mutant. The promoting effect of continuous and cyclic far-red light in the au mutant can be attributed to a greater sensitivity to P_fr.     

Cause of Senescence of Nine Sorts of Flowers

The levels of endogenous phytohormones and respiratory rate in nine sorts of flowers such as Cymbidium faberi Rolfe, Nopalxochia ackermannii Kunth and others were investigated both at full bloom and senescence and meanwhile the effect of exogenous phytohormones on prolonging the blossoms and promoting ethylene production were tested. There is a high content of endogenous ethylene in all the long-lived flowere, about 3–16 folds higer than the short-lived ones. There is a high level of ABA at full blooming flowers of short-lived flowers, in which there is no or only some cytokinins in it, but the ratio of CTK (6BA+zeatin)/ABA is smaller(l.7). The endogenous ABA reached a much higher level at senescence in all nine sorts of flowers, so it is reasonable to consider that it is ABA which plays an important role of regulation in controlling flower's senescence. There is a much higher level of GA3 and zeatin in the long-lived flowers which is not demonstrated in the shortlived ones. The respiratory rate is one of the factors controtling the longevity of flowers, but it does not play a decided role. Application of 6BA and zeatin prolongs distinctly orchid’s longevity, however exogenous IAA through the promotive action on ethylene production, evidently extends the longevity of the flowers of the Nopalxochia ackermannii Kunth.

Interconnection of parameters of regulation system of lipid peroxidation and of morphophysiological parameters of mouse liver

A complex analysis of seasonal fluctuations of the mean group parameters of the system of regulation of lipid peroxidation has been performed in liver of Balb/c mice. Association of lipid characteristics and morphophysiological parameters is studied in the Balb/c mouse liver. An inter-connection is revealed between the liver index and the amount of lysoforms of phospholipids, the scale and character of the interconnection differing essentially depending on proportion of phos-phatidylcholine in mouse liver phospholipids.     

The effects of glutamine of the maintenance of embryogenic cultures of Cryptomeria japonica

Summary Embryogenic tissues of sugi (Cryptomeria japonica) were induced on a modified Campbell and Durzan (CD) medium containing 1 μM 2,4-dichlorophenoxyacetic acid (2,4-D) and 600 mg l⁻¹ glutamine, and subcultured in the medium of the same composition for over 1 yr. This resulted in a mixed culture of embryogenic and non-embryogenic cells. When embryogenic cells were isolated and cultured independently, their capacity to form embryogenic aggregates was lost. Thus, the non-embryogenic cells present within a mixed culture system were essential to the formation of embryogenic aggregates. When embryogenic tissues were isolated and cultured independently on a high glutamine-containing (2400 mg l⁻¹) medium, dry weights and endogenous levels of glutamine increased, and the tissue could generate a large number of embryogenic aggregates. Amino acid analysis of embryogenic and non-embryogenic cells from the maintenance culture indicated a higher level of glutamine was present in the latter. The high endogenous level of glutamine in the non-embryogenic portion of mixed cell masses may be the supplier of glutamine for maintaining the embryogenic property of the tissues.     

Specificity of action of piperidylcholine derivatives as substrates of cholinesterases of various origin

The review deals with study of enzymologic properties of a novel highly specific acetylcholinesterase substrate, N-(β-acetoxyethyl) piperidinium iodomethylate (“piperidylcholine”), and its 30 derivatives that were tested as effectors of cholinesterases of mammals and various species of Pacific squids. It was proven for the first time that responsible for specificity of action was structure of cyclic ammonium grouping of the alcohol part of molecule of the ester substrate. Analysis of specificity is performed based on enzymatic hydrolysis parameters—activity of catalytic center of cholinesterases and bimolecular constant of the reaction rate that are determined at optimal and low substrate concentrations. Among the specially synthesized group of thioester compounds there is revealed one more highly specific acetylcholinesterase substrate—N-(β-acetoxyethyl) piperidinium.
