摘要 目的：探讨与分析血清总胆固醇（TC）、甘油三脂（TG）和低密度脂蛋白胆固醇（LDL-C）水平与老年卵巢良恶性肿瘤的相关性。方法：2018年8月至2021年4月选择在本院诊治的老年卵巢癌患者72例与老年良性卵巢肿瘤患者72例作为恶性组与良性组,同期选择在本院进行健康体检的老年人72例作为正常组。检测三组血清TC、TG、LDL-C水平、血清肿瘤标志物水平并进行相关性分析。结果：恶性组、良性组的血清TC、TG和LDL-C水平高于正常组,恶性组高于良性组（P<0.05）;三组的血脂异常率分别为77.8 %、44.4 %和6.9 %,对比有差异（P<0.05）。恶性组、良性组的血清CA125、CA153和CA199水平高于正常组,恶性组高于良性组（P<0.05）。在老年卵巢肿瘤144例患者中,偏相关分析显示：TC、TG、LDL-C、CA125、CA153、CA199与卵巢癌存在相关性（P<0.05）;Pearson分析显示：TC、TG、LDL-C与CA125、CA153、CA199存在相关性（P<0.05）。二元Logistic回归分析显示：TC、TG、LDL-C均为导致卵巢癌发生的影响因素（P<0.05）。结论：老年卵巢良恶性肿瘤患者多伴随有血清TC、TG和LDL-C水平的异常,与血清肿瘤标志物水平存在相关性,是引发老年卵巢癌发生的重要因素。     

Decreased Cerebrospinal Fluid Glutamine Levels in Patients with Benign Brain Tumors

Abstract: CSF glutamine concentrations were studied in 12 patients with benign brain tumors (meningioma, craniopharyngioma, or osteofibroma), 12 patients with malignant brain tumors (astrocytoma, medulloblastoma, pinealoblastoma, or chondrosarcoma), 9 patients with non-cerebral tumors, and a reference group of 24 patients. The mean ± SD levels in the benign tumor group (424 ± 124 μ M ) were significantly lower (p < 0.0004) than those in the reference group (642 ± 195 μ M ). There was no significant difference between the CSF glutamine concentrations in the malignant cerebral tumor group (643 ± 210 μ M ) or noncerebral tumor group (599 ± 127 μ M ) and those in the reference group. In patients with benign brain tumors there was indication of an inverse linear relationship between the logarithm of CSF glutamine concentration and tumor diameter.

Oral lesions in elderly population: a biopsy survey using 2250 histopathological records

Objective: To perform an oral biopsy survey focused on the incidence of oral lesions in Brazilian elderly patients. Methods: A total of 17 329 oral biopsy records were analysed and divided into two age groups: elderly patients, ≥60 years old; and non‐elderly patients, <60 years old. Information about sex, race, age and histopathological diagnosis (categorised in non‐neoplastic and neoplastic lesions) was collected. Differences of diagnosis incidence were tested by comparison between two proportions (binomial test). Results: The incidence of epithelial malignant neoplasms and pre‐malignant lesions in the elderly group was higher than non‐elderly group, as well as autoimmune diseases and salivary gland tumours. The three most prevalent lesions in the elderly group were inflammatory fibrous hyperplasia, squamous cell carcinoma, and fibroma. Conclusion: The distribution of oral diseases using biopsies allows greater accuracy in data about oral health of elderly patients, especially when considering malignant and pre‐malignant lesions.

Incidence of Anticonvulsant Osteomalacia and Effect of Vitamin D: Controlled Therapeutic Trial

The bone mineral content (B.M.C.) in both forearms (related to total body calcium) was measured by photon absorptiometry for a controlled therapeutic trial in a representative sample of epileptic outpatients, comprising 226 patients treated with one or two major anticonvulsant drugs (phenytoin, phenobarbitone, primidone).Initially the mean B.M.C. value for all epileptic patients was 87% of normal. During treatment with 2,000 international units of vitamin D₂ daily for three months an average B.M.C. increase of 4% was found, whereas the B.M.C. values remained unchanged in the placebo group and in the control groups. The incidence of hypocalcaemia and raised serum alkaline phosphatase was 12% and 43% respectively. The biochemical indices of osteomalacia were related to B.M.C. These results indicate that epileptic patients should be closely supervised for the occurrence of anticonvulsant osteomalacia, and, possibly, receive prophylactic treatment with vitamin D.

Effects of different methods of treatment of primary enuresis on psychologic functioning in children.

Sixty-two children with primary nocturnal enuresis were assigned randomly to one of two groups. Group 1 was treated with imipramine hydrochloride, and group 2 received a course of treatment with the Mozes Detector. Seventeen children from group 1 and 18 from group 2 were tested with the age-appropriate form of the Cattell personality questionnaire on three occasions: at the time of entry into the study, 2 months later and at follow-up, an average of 16 months later. The patients in group 2, who were older, had a higher rate of cure than did the patients in group 1. They also had significantly higher levels of extroversion and significantly lower levels of neuroticism at follow-up than did those in group 1. These findings indicate that better results are seen with the Mozes Detector than with imipramine in older children with primary nocturnal enuresis.

Serum and tissue trace elements in patients with breast cancer in Taiwan

The objective of this study was to compare levels of four elements (zinc, copper, selenium, and iron) in the serum and tissue of 68 breast tumor patients (benign and malignant), from a teaching hospital in central Taiwan. Samples of normal tissue (5 cm away from tumor) were also taken from patients with malignant tumors. Only serum was taken from the 25 healthy persons in the control group. Results showed that Zn, Cu, Se, Fe, Cu/Zn, Cu/Se, and Cu/Fe were present in different amounts in the serum of each of the three groups. Zn and Se levels were lower in the serum of the two tumor groups compared to the control group. In tissue samples, Zn, Cu, Se, and Fe concentrations were different in each of the three groups. The malignant tissue had the highest levels of all four elements. In advanced-stage malignant tumors, levels of Cu and the ratios of Cu/Fe and Cu/Zn (in both serum and tissue) were highest. The ratios of serum Cu/Zn, Cu/Fe, and Cu/Se were also higher in malignant patients. The cutoff value of serum Cu/Zn was 1.2 (sensitivity and specificity were both 100%). The Cu/Zn ratio was highest in the advanced stages of cancer and was a better diagnostic tool for breast cancer than Cu/Se and Cu/Fe. The authors suggest that change of trace elements in serum and tissue might be useful and significant as biomarkers involving the initial plastic process.

Titration of natural and disease-related cytotoxicity of lymphocytes from bladder cancer patients

Summary A controlled investigation of lymphocyte-mediated cytotoxicity has been carried out in patients with transitional cell carcinoma (TCC) of the urinary bladder, three long-term established cell lines with comparable sensitivities to the natural cytotoxicity (NC) being used as targets, namely HU 456 derived from human TCC, HU 609 from normal human urothelium, and SAOS 2 from a human osteosarcoma. The 44-h incubation microcytotoxicity assay (MA) was used with blinded semiautomatic visual counting of target cells. The cytotoxicity was determined by titration with a serial dilution of lymphocyte suspensions 1:2, five different concentrations being used in each experiment. Fifty tests were performed with lymphocytes from 48 TCC patients. As controls, 65 patients with diseases other than TCC were tested simultaneously. The average cytotoxicity of lymphocytes from TCC patients against HU 456 was only slightly and insignificantly higher than that of the control patients. However, a marked decrease of the NC against the control cells HU 609 and SAOS 2 was noted with TCC patient lymphocytes.After correction of the data for the depression of background NC, increased tumor-specific cytotoxicity (TSC) and tumor type-specific cytotoxicity (TTSC) were demonstrated in TCC patients with noninvasive malignant tumors (grade 2 or 3), whereas no increased specific cytotoxicity was found in TCC patients with invasive grade 2 or 3 tumors. Neither was any increased specific cytotoxicity found in patients with very well-differentiated grade tumors. The presence of specific reactivity in patients with noninvasive TCC in contrast to invasive TCC is supposed to indicate growth-controlling function of the cellular immune reaction.Tests were also performed with lymphocytes from 35 patients in the postoperative phase without any history of TCC. Surprisingly, this group revealed a significantly elevated TSC but not increased TTSC when compared with the 65 untreated control patients, thus indicating that serious reservations must be made in the interpretation of the cytotoxocity assay.
