Changing helplessness to coping: an exploratory study of social skills training with individuals with long-term mental illness

The primary purpose of this study was to apply an occupational therapy programme for social skills training based on a cognitive-behavioural frame of reference to individuals with long-term mental illness. The goal of the social skills training group was to enable patients to develop verbal and non-verbal communication skills that could be generalised to everyday interpersonal encounters. A case example of the application of social skills training with a 38-year-old single male with a diagnosis of paranoid schizophrenia is described. The Group-Interaction Skills Survey developed by the author served as an outcome measure. Qualitative data confirmed the researcher's hypothesis that individuals with long-term mental illness can benefit from social skills training using a combination of role-playing, sociodrama, videotape recordings and creative media.

Effects of Polyethyleneglycol Chain Length and Phospholipid Acyl Chain Composition on the Interaction of Polyethyleneglycol-phospholipid Conjugates with Phospholipid: Implications in Liposomal Drug Delivery

Purpose. The purpose of this study was to investigate polyethyleneglycol(PEG)-phosphatidylethanolamine(PE) conjugate interaction with phospholipid bilayers, in an attempt to explain the dependence of liposome circulation time on formulation. Methods. Differential scanning calorimetry, electron microscopy, dynamic light scattering and NMR were the major methods used in the study. Results. Mixtures of PEG-phospholipid conjugates and phosphatidylcholine existed in three different physical states: a lamellar phase with components exhibiting some miscibility, a lamellar phase with components phase separated, and mixed micelles. Beyond 7 mol% of PEG(l,000–3,000)-dipalmitoyl phosphatidylethanolamine (DPPE), and 11 mol% PEG(5,000)-DPPE in dipalmitoyl phosphatidylcholine (DPPC), a strong tendency towards mixed micelle formation was observed. All concentrations of PEG(12,000)-DPPE and PEG(5,000)-DPPE beyond 8 mol% formed phase separated lamellae with phosphatidylcholine. Decreasing the acyl chain length from C_16:0 to C_14:0 caused a decrease in tendency towards micelle formation and phase separation. These tendencies increased upon increasing acyl chain length to C_18:0. Phase separation was at least partly due to PEG chain-chain interaction. This was supported by an increased fraction of PEG chains exhibiting a fast NMR transverse relaxation in DPPC/PEG(5,000)-DPPE mixtures as compared to that in distearoyl phosphatidylcholine (DSPC)/PEG(5,000)-dioleoyl-PE (DOPE). Conclusions. These phenomena are discussed in relation to both bilayer and steric stabilization of liposomes, and the lack of prolonged circulation with certain formulations is discussed.     

中国中原地区33555名妇女妇科疾病发生情况与五种因素关系的调查报告

自１９９２年３月至１９９４年５月，对中原地区４个省２０多个县（市）近２００个单位３３５５５名２０～７５岁的已婚妇女，进行妇科疾病发生情况与年龄、职业、文化、月经、孕产等五种因素关系的调查分析。在３３５５５名妇女中，患病者２２３７０人，总患病率为６６．６７％，查出妇科疾病４２种，计７６９７４例次。结果证明：以２５～３５岁年龄组发病率最高，其中以内生殖器炎症为主；职业以经商者发病率高，特别是性病患者高于其他职业者二倍以上；文化程度以小学、初中者发病率高，尤其宫颈炎更明显；月经情况：随着经前期紧张综合征的加重，更年期综合征发病率增高；孕产次数越多，患病率越高。本次调查未发现宫颈癌，进一步证明我国对妇女保健工作的关心和重视。     

Characteristics of prolidase and prolinase in prolidase-deficient patients with some preliminary studies of their role in skin

• 1) The prolidase (Pd) and prolinase (Pn) activities of cultured skin fibroblasts derived from two prolidase-deficient sisters, the elder with typical clinical manifestations [symptom (+)] and the younger with only slight clinical manifestations [symptom (–)] were examined biochemically. Pd activity against several substrates other than Gly-Pro were present to some degree in both sisters. There were no detectable differences in Pd activity between the symptom (+) patient and the symptom (–) sister. Pn activity seemed to be increased in both. The lower Pn activity found against Pro-Gly as compared with those against other substrates indicates that Pro-Gly, which has been used for Pn assays in most previous reports, may not be the best substrate for this test. Pd derived from control fibroblasts was activated by Mn²⁺ against all substrates tested in this experiment. Cu²⁺, Hg²⁺, Cd²⁺ and Zn²⁺ remarkably inhibited enzyme activity, Co²⁺ slightly inhibited it, and neither Mg²⁺ nor Fe²⁺ had any remarkable effect. The Pd derived from the prolidase-deficient patients was also activated by Mn²⁺. This Pd seemed to be more inhibited by Co²⁺ than was the control. However, we found no remarkable differences between the two patients.
• 2) We also studied Pd and Pn activities in rat skin and blood during wound healing. Pd and Pn activities adjacent to the wound increased in parallel with fibroblast proliferation. Pd activity was also detected in an extract of newborn mouse epidermis.

     

肉桂挥发油对“虚证”模型环核苷酸系统反应性的影响

本实验用纯系CFW小鼠与Wistar大鼠建立“虚证”模型。以环核苷酸系统反应性为指标观察了肉桂挥发油的作用。通过气相色谱及气质联用等方法研究表明,本实验所提取的挥发油中桂皮醛含量约为92％。肉桂挥发油可显著降低“阳虚”——甲状腺素缺乏(甲减)模型升高了的cGMP系统反应性而使其降低了的耗O_2率升高;这是一种治疗作用。肉桂挥发油可显著升高“阴虚”——甲状腺素过多(甲亢)模型已升高了的cAMP系统反应性并使其升高了的耗O_2率进一步升高,这是一种恶化作用。这两种作用与中医对症治疗的原则是一致的。     

四川省绵阳市2019—2021年流行性感冒流行病学特征分析

目的 了解绵阳市2019—2021年流行性感冒流行病学特征,为绵阳市流感防控工作提供重要依据。方法 收集绵阳市2019—2021年流感监测相关数据,采用描述性流行病学方法进行统计学分析。结果 绵阳市2019—2021年流感共报告发病55 970例,年均报告发病率388.08/10万。报告流感样病例（influenza-like illness cases, ILI） 103 723例,年平均ILI%为3.58%。2019年流感报告发病率、ILI%、阳性检出率均远超过历年同期水平。人群分类构成以15岁以下学生为主。报告发病数居前三位的地区分别为涪城区20 118例（占35.94%）、游仙区6 394例（占11.42%）、江油市5 800例（占10.36%）。2019—2021年共收到并检测ILI标本10 126份,阳性率19.53%;标本阳性检出率以15岁以下学生为主。历年流感病毒优势毒株呈现出交替流行的趋势,2019年以A（H3）型为主,2020年受新冠疫情影响,全年阳性检出率均较低,2021年除检出2份A（H9）型外,其余均为BV型。2019—2021年共报告ILI暴发疫情43起,发生时间主要集中在冬季,场所以小学居多。结论 2019—2021年绵阳市流感病例、ILI、病原学监测、暴发疫情的特征基本一致,15岁以下的学生及学校仍为重点关注人群及场所。而新型冠状病毒肺炎疫情大流行下,流感的低发水平进一步印证非药物干预措施对流感防控工作的重要性。

Debrancher deficiency neuromuscular disorder with pseudohypertrophy in two brothers

Summary A neuromuscular disorder is reported in two brothers, aged 28 and 38 years, with glycogenosis type III. Both patients had proximal weakness, pseudohypertrophy of sternocleidomastoid. trapezius and quadriceps muscles, mild distal wasting and myopathic EMG changes. Pseudohypertrophy was more evident in the younger brother, whereas weakness was prominent in the older one. In the former, muscle biopsy revealed vacuolar myopathy and virtual absence of amylo-1,6-glucosidase enzyme. Few familial cases of debrancher deficiency neuromuscular disorder have been reported. Distal wasting has been considered a quite characteristic manifestation of the disease. It is also suggested that this particular kind of pseudohypertrophy may represent a distinctive feature of glycogenosis type III.     

呼出气氢测定试验对飞行人员乳糖酶缺乏症的研究

对66名汉族飞行人员进行乳糖呼出气氢测定试验,乳糖吸收不良的发生率为83.3％,其中乳糖不耐受者占34.6％;与一般汉族人群无明显差别。对10名确定为中度以上乳糖吸收不良的飞行人员进行250ml鲜牛奶的试验结果,有50％呼出气氢含量在正常范围,并无一例出现胃肠道症状。提示较长期食用牛奶未能使乳糖酶缺乏状态发生改变,但每日食用适量牛奶属合理营养。     

Determination of nickel in lung specimens of thirty-nine autopsied nickel workers

Summary Lung specimens from 39 nickel refinery workers autopsied during the period from 1978 to 1984 were analyzed for nickel. Fifteen of the workers were employed in the Roasting and Smelting Department, where exposure to nickel was predominantly in the form of nickel-copper oxides, Ni₃S₂ and metallic dust. The remaining 24 men worked in the Electrolysis Department. Exposure in this group was considered to be mostly to the water-soluble compounds, NiSO₄ and NiCl₂, but also to a lesser degree to water-insoluble nickel compounds such as nickel-copper oxides and sulphides. The arithmetic mean ± SD for nickel concentration in lung tissues expressed in gg^–1 dry wt for the 39 workers was 150 ± 280. In the workers employed in the Roasting and Smelting Department, the average nickel concentration was 330 ± 380; for those who worked in the Electrolysis Department it was 34 ± 48. Lung tissue from 16 autopsied persons not connected with the refinery had an average nickel concentration of 0.76 ± 0.39. Statistical analysis based on log-normal distributions of the measured nickel concentrations allowed three major conclusions to be formulated: (1) nickel refinery workers exhibit elevated nickel levels in lung tissues at autopsy; (2) workers of the Electrolysis Department and the Roasting Smelting Department constitute distinct groups with respect to the accumulation of nickel in lung tissue; (3) workers who were diagnosed to have lung cancer had the same lung nickel concentrations at autopsy as those who died of other causes.
