米利酮对豚鼠心乳头肌及主动脉条的作用

米利酮是非洋地黄，非儿茶酚胺类强心药，具有明显的正性肌力和扩血管作用。国外用于治疗难治性心衰及洋地黄中毒的心衰病人。本文用豚鼠乳头肌及主动脉条进行实验，结果表明合成与进口米利酮的正性肌力作用效价相同，对抗去甲肾上腺素缩血管的作用也等同。     

一种中西药复方制剂(PESM)对大鼠实验性肾结石形成的抑制作用

用乙二醇法诱导大鼠产生草酸钙结石，用45~Ca示踪测定法了解中草药复方制剂（PESM）对草酸钙结石形成的抑制作用。结果显示，实验组肾脏放射性强度明显减少（实验组3.47±3.52cpm／mg，对照组10.89±14.24cpm／mg）。干肾重量明显下降（实验组306.0±47.0mg，对照组343.1±59.4mg），说明PESM能明显抑制肾脏草酸钙结石的形成。

Presence of ghost cells and the Wnt signaling pathway in odontomas

BACKGROUND: Although it has been reported that ghost cells are present in odontomas, the generation mechanism of these cells is unclear. To evaluate the presence of ghost cells and involvement of the Wnt signaling pathway, we examined the expression of hard keratins, beta-catenin and Lef-1 in odontomas. METHODS: Sixty-nine cases of odontoma were examined immunohistochemically with the use of antibodies against human hair proteins, beta-catenin and Lef-1. RESULTS: Expression of hard keratins was found only in the cytoplasm of ghost cells in 46 (66.7%) of the 69 odontomas. Compound odontomas (78.8%) showed a higher incidence of ghost cells than complex odontomas (29.4%). Histopathologically, ghost cells were found within odontogenic epithelium adjacent to immature enamel and in the centre of Liesegang-ring-like calcified materials. Expression of beta-catenin and Lef-1 was observed in the cytoplasm and nucleus of odontogenic epithelial cells adjacent to the ghost cells in immature odontomas. CONCLUSION: These findings suggest that odontoma is a hard keratin-expressing tumor-like lesion, and that the Wnt signaling pathway may be involved in the formation of ghost cells in odontomas.     

Study on Tongkuaixiao Babu plaster in treating cancer pain

Objective: To explore the efficacy of Tongkuaixiao Babu plaster (TKXBBP) in treating cancer pain.Methods: In the clinical observation, sixty-five patients with moderate or severe cancer pain were randomly divided into two groups: 32 in the treated group (TKXBBP group) and 33 in the control group (Bucinnazine group). The therapeutic effects in relieving pain, improving quality of life (QOL), and the rate of satisfaction the patients felt of the two groups were compared respectively. Results: TKXBBP was effective in treating cancer pain. There wasn’t any statistically significant difference in total effective rate (P>0.05), but the statistical difference was significant in obvious remission rate (P<0.05) between the treated and control group, and the effect on serious pain shown in the treated group was better than that of the control group (P<0. 05). The difference in the initiation time of relieving cancer pain was insignificant (P>0.05), while in the remission period, the treated group showed its treatment was obviously superior to that of the control group (P<0.05). TKXBBP showed better effect in the improvement of QOL (P<0.05) and satisfaction rate, with significant difference between the treated and the control groups (P<0.01).Conclusion: TKXBBPs effect in treating cancer pain was obvious, its application was safe and convenient. It was shown that the external treatment with this kind of Chinese medicine had great advantage in treating cancer pain.     

骨骼肌钝挫伤后愈合质量的肌电评价

目的 :观察大鼠骨骼肌钝挫伤后 ,不同干预方法对骨骼肌修复过程中肌电信号的影响 ,研究肌电图在骨骼肌损伤愈合过程中的评价作用。方法 :10 8只雄性SD大鼠 ,利用自制的重物坠落打击装置造成右侧腓肠肌钝挫伤。随机分成 3组 ,即胰岛素样生长因子 - 1(IGF - 1)组、中药组和自然愈合组 ,分别于损伤局部注射IGF - 1、黄芪丹参注射液、不作处理。于伤后第 2、5、7、10、14、2 1、2 8、35、5 6天观察并比较双侧腓肠肌的肌电图变化 ,记录纤颤电位和正尖波等自发活动 ,分析复合肌肉动作电位 (CMAP)并测量其潜伏期和波幅 ,观察伤后CMAP的变化。结果 :(1)各组大鼠均于伤后第 2～ 5天出现纤颤电位和正尖波 ,约至第 7～ 10天达到高峰 ,然后逐渐减少。以IGF - 1组最早消失 ,中药组次之。 (2 )各组大鼠的伤侧肌电图CMAP中的潜伏期逐渐缩短 ,波幅逐渐增高。以IGF - 1组最快 ,中药组次之 ,自然愈合组最慢。 (3)伤后第 8周 ,IGF - 1组和中药组大鼠损伤侧CMAP波幅接近正常 ,自然愈合组则显著低于其它两组。结论 :(1)肌电图检测证实 ,IGF - 1和黄芪丹参注射液均具有促进骨骼肌损伤愈合的作用 ,但以IGF - 1的作用更明显。 (2 )损伤肌肉局部肌电信号的变化 ,可以用来评价损伤骨骼肌的修复进程和愈合质量     

Is dietary counselling effective in increasing dietary calcium,protein and energy intake in patients with osteoporotic fractures? A randomized controlled clinical trial

To determine the feasibility of increasing the calcium, protein and calorie intake of osteoporotic fracture patients by repeated dietary counselling delivered by a dietitian, a randomized controlled trial was conducted. Among 189 patients presenting with osteoporotic fractures to an Orthopaedics and Traumatology Department of a large regional hospital, 98 patients were randomized to the intervention group and 91 were randomized to the control group (with usual care). Intervention group received three sessions of dietary counselling with tailored made recommendations over a period of 4 months, while the control group only received dietary assessment and pamphlets on the prevention of osteoporosis. Almost all subjects in both intervention and control groups had calcium intake below the recommended level of 1000 mg at baseline. Half and 60% of subjects in both groups had total energy and protein intake below recommended levels respectively. The mean weights of control and intervention groups at baseline were 51.5 and 50.9 kg respectively, while the body mass index (BMI) were 22.6 (kg m(-2)) and 22.6 (kg m(-2)) respectively. After dietary intervention, significant increase of intake was seen in calcium intake (P = 0.0095 by t-test) in the intervention group. No significant increase was seen in protein or calorie intake. No significant change was observed in the body weight or BMI although there was a positive trend in the intervention group for all these parameters. We concluded that there was general malnutrition in Chinese elderly who presented with osteoporotic fractures. Dietary calcium could be increased by repeated professional dietary counselling. Future studies with longer duration and more objective clinical outcomes will be helpful to further demonstrate the long-term effects of dietary intervention on osteoporosis and other chronic diseases.
