Evaluation of Training Course Effects on Integrated Sexual and Reproductive Health Counseling

Since the International Conference on Population and Development held in Cairo in 1994, and the Fourth World Conference on Women held in Beijing in 1995, the international organizations and public health communities have paid more attention to reproductiv…     

Prospect of Endoscopic Mucosal Resection for Early Gastric Cancer: Our Devices in Insulated‐Tip Electrosurgical Knife Method

In Kobe University Hospital, a new method for endoscopic mucosal resection (EMR) using insulated‐tip electrosurgical knife (IT‐EMR) for early gastric cancer (EGC) was introduced from November 2001. To achieve an effective and safe IT‐EMR procedure, we use a high‐frequency surgical unit for cutting and coagulation (ERBOTOM ICC 200) with automatically controlled cutting mode (ENDOCUT). In this study, we show not only our results of IT‐EMR for EGC in comparison with those of the conventional strip biopsy method, but also the optimal conditions for the apparatus of a high‐frequency surgical unit to prevent complications such as bleeding and perforation.     

采血者针刺伤的调查及危险因素分析

针刺伤在采血工作中经常发生，其危害大，后果严重，一般情况下还没有引起人们足够的重视。我国是肝炎的高流行区，近年来艾滋病在我国的发病率呈倍增的趋势。血液污染的针刺伤是导致血站采血人员发生血源性传染病最主要的职业因素。作者从实际工作出发，收集相关资料，系统的阐述了针刺伤的发生因素及预防措施等，并结合相关理论提出了一系列的措施和建议。     

胎儿生长迟缓与新生儿胰岛素敏感性变化的相关性

目的探讨胎儿生长迟缓(FGR)与新生儿胰岛素敏感性变化的关系。 方法昆明医学院第一附属医院于2004年4~12月，对72例小于胎龄儿(SGA)和48例适于胎龄儿(AGA)空腹血糖(FPG)、空腹胰岛素(FINS)、C 肽、HDL C、LDL C、TG、非酯化脂肪酸(NEFA)等指标，计算葡萄糖/胰岛素比值(G/I)、胰岛素敏感性指数(ISI)、胰岛素抵抗指数(HOMA IR)、胰岛β细胞功能(HBCI)等，探讨FGR与新生儿胰岛素敏感性变化的关系。 结果(1)SGA组FPG、HDL C低于AGA组，而FINS、LDL C、TG、NEFA高于AGA组(P<001)；(2)SGA组G/I比值、ISI低于AGA组，HOMA IR高于AGA组(P<001)，而HBCI两组相比差异无显著性(P>005)。 结论FGR儿在生命早期存在胰岛素敏感性降低和不同程度的胰岛素抵抗(IR)，而胰岛β细胞功能无明显变化。     

1 alpha(OH)D3 (ETALPHA) treatment and receptor studies in 16 patients with chronic and myeloproliferative disorders

10 patients with CLL and 2 with CML were treated with gradually increasing doses of 1 alpha(OH)D3, up to 4 micrograms daily during 6 wk. 3 patients with preleukemia and 1 with myelofibrosis were treated with 2 micrograms daily of 1 alpha(OH)D3 for a prolonged period up to 17 wk. The treatment with 1 alpha (OH)D3 did not result in changes of disease parameters in any of the patients under study. Receptor studies for 1,25(OH)2D3 were performed in 8 CLL patients and revealed only 1 patient with increased specific receptor binding capacity. The maximum tolerable dose of 1 alpha(OH)D3 varied individually, but was in the range of 2-4 micrograms daily.     

Biochemical activities of lysosomal acid hydrolases in leukemic cells

The biochemical activities of 8 lysosomal acid hydrolases in leukemic cells from 48 patients were examined. Characteristic alterations were found in α-mannosidase, β-galactosidase and N-acetyl-β-glucosaminidase activities of leukemic cells. The level of α-mannosidase activity was much higher in myelo(mono)genous leukemias (AML, AMoL, AMMoL, CML and CMMoL) than in lymphogenous ones (ALL, T-cell leukemia, hairy cell leukemia and CLL) without exception. The β-galactosidase activity also differed as a result of α-mannosidase, except in T-cell leukemia. In T-cell leukemia it was within the range of normal lymphocytes, but in the other lymphogenous leukemias it was significantly below normal. N-acetyl-β-glucosaminidase activity in myelo(mono)genous leukemic cells was above the range of normal granulocytes. The changes in these enzyme levels were consistent. The lymphocytic or myelocytic nature of three cases of acute undifferentiated leukemia could be determined by enzyme studies. In two cases it was lymphocytic and in one it was myelocytic. The enzymatic abnormalities were also found in morphologically mature neutrophils from patients with not only chronic types (CML, CMMoL) but also acute types (AMoL, AMMoL) of leukemias, and were similar to those of their respective leukemic cells. Analysis of lysosomal enzymes (at least three of those mentioned above), can elucidate one of the biochemical properties of leukemic cells and may be valuable in the differentiation of leukemias.

本文对武汉地区健康老年人(60岁以上)81人和老年前期(45～59岁)75人进行了动脉血气检测,以探讨健康老年人血气及酸碱之正常参考值。其结果:pH 7.44±0.03,PaCO_2 4.77±0.65kPa,PaO_2 10.89±1.03kPa,HCO_3-24.08±3.02mmol/L,BE 0.75±2.77mmol/L,TCO_2 25.25±3.15 mmol/L,SaO_2 0.96±0.01,老年人与老年前期相比较,差别不明显(P>0.05)。     

Evidence for frequent divergence impairment in French dyslexic children: deficit of convergence relaxation or of divergence per se?

Aim There is a controversy as to whether dyslexic children present visuo-motor disabilities such as vergence and accommodative problems assessed with orthoptic tests. The purpose of this study is to re-examine this issue in a large population of children. Methods Extensive orthoptic evaluation was made in 57 dyslexic and 46 non-dyslexic (“normal”) age-matched children. Convergence and divergence capacities were evaluated at two distances (30 cm and 400 cm). Results Binocular vision measured with stereo-acuity tests was normal in dyslexics. In contrast, the near point of convergence was significantly more remote in dyslexics; most importantly, divergence at both far and near distance was significantly more reduced in dyslexics (median value 4 pD and 10 pD, respectively, at far and near) than in “normals” (median value 6 pD and 12 pD, at far and near). Conclusion The existence of the divergence deficit at far distance indicates the presence of deficit of divergence per se, independently from convergence and accommodation relaxation. This result is novel and corroborated by physiological studies indicating distinct control of convergence and divergence, both at the cortical and subcortical premotor level. We conclude that vergence deficits are frequently present in dyslexics, and that dyslexics should be re-educated; training should address distinctively convergence and divergence subsystems.
