电针膝眼穴治疗膝骨性关节炎的临床研究

为观察电针膝眼穴治疗膝骨性关节炎的临床疗效与安全性，将60例膝关节OA患者随机分两组。电针组予电针膝眼穴治疗，扶他林组予口服扶他林缓释片，采用西安大略和麦克马斯特骨关节炎调查量表（WOMAC）进行评估。结果显示，治疗4周后，两组的WOMAC总积分、僵硬与功能积分下降明显（P〈0．0．5），疼痛积分下降无明显差异（P〉0．05）；电针组不良反应发生率显著低于扶他林组（P〈0．05）。结论表明，电针膝眼穴治疗膝关节骨关节炎有显著疗效厦安全性良好。其在僵硬和功能的改善上明显优于扶他林缓释片。     

中药对中晚期三阴乳腺癌的生存影响及中医治疗策略探讨

目的：观察辨证服用中药对三阴乳腺癌的生存影响并探讨中医治疗策略。方法：采用队列研究的方法依据治疗方法的不同将101例三阴乳腺癌分为2个队列,辨证服用中药联合西医治疗队列及单纯西医治疗队列。中药1剂／d,服药至少半年或至肿瘤进展;西医按照美国综合癌症治疗网指南给予相应的治疗。随访3年观察患者3年疾病无进展生存（PFS）及患者生存质量。结果：Kaplan—Meier生存曲线显示,中西医结合组的3年PFS较单纯西药治疗组显示一定优势,有统计学意义（P〈0．05）。COX回归分析2组未见统计学意义（P〉0．05）。化疗脑及肢体麻木症状在服药1个月后统计显示有明显改善（P〈0．05）。结论：辨证服用中药可能对患者的生存有益,需要扩大病例数进一步研究证实。中药可改善因化疗引起的麻木及化疗脑,从而提高生活质量。     

Effect of blending sewage sludge with coal on combustion and ash slagging behavior

Blending sewage sludge (SS) with Zhundong coal (ZDC) for combustion in coal-fired power plants is a recent approach that can alleviate the shortage of high-quality coal resources and achieve the harmless treatment of SS, while also having a significant influence on combustion and ash slagging. Due to the high content of alkali and alkaline earth metals (AAEMs) in ZDC, its combustion ash has a strong likelihood of slagging. This study aims to investigate the effect of blending SS with ZDC on combustion and ash slagging. Thermogravimetry (TG) results indicate that blending with SS could lower the ignition and burnout temperatures of ZDC. With an increase in the ratio of sludge, the comprehensive combustion index (S) first increases and then decreases, showing that blending SS with ZDC in an appropriate proportion could improve the overall combustion. Through the analysis of the interaction, it is confirmed that SS and ZDC could complement each other during co-combustion due to their different components. X-ray fluorescence (XRF) was used to test the ash components of different blending ratios (10–30%) and combustion temperatures (800–1100 °C). Slagging indices including alkali acid ratio (B/A), silicon ratio (G), and silica–alumina ratio (SiO₂/Al₂O₃) were also calculated. The results suggest that the slagging behavior of ZDC is greatly reduced even if the blending ratio is only 10%. However, with an increase in the blending ratio, the effect on slagging gradually weakens. Considering the dual influence of SS blending on combustion and slagging, this study assumes the optimal blending ratio of 20%. Influenced by the components of the combustion ash, B/A and SiO₂/Al₂O₃ are more suitable for evaluating the slagging tendency of ash; however, there is great deviation in the results for G. This research is beneficial to coal-fired power plants for the selection of operation parameters during co-combustion with SS.

Computed tomography imaging features for amyloid dacryolith in the nasolacrimal excretory system: A case report

BACKGROUNDNasolacrimal duct obstruction leading to epiphora is a common ophthalmologic complaint, and it may derive from amyloidosis in rare cases. There are a few reports about localized amyloidosis, and amyloidosis with involvement and obstruction of the nasolacrimal duct is exceedingly rare. CASE SUMMARYA 54-year-old male presented with a 2-year history of a lump overlying the left lacrimal sac that had grown rapidly for nearly half a year. Physical examination touched a firm lump in the left lacrimal sac. Nasal endoscopy discovered lesions in appearance of sediments with easy bleeding at the entry of the nasolacrimal duct of the left inferior nasal meatus. Computerized tomography scan revealed speckle high density in the left lacrimal sac and the dilated nasolacrimal duct. During an endoscopic exploration and excision, a large number of dacryoliths were exposed. Pathology indicated amorphous pink material and multinucleated giant cell reaction in the fibrous tissue.CONCLUSIONThis case showed amyloidosis in localized form mimicking dacryolith with nasolacrimal duct obstruction. In clinical practice, we should be aware of the possibility of localized amyloidosis in the nasolacrimal excretory system.     

运动性心律失常

运动性心律失常是指发生于机体剧烈运动期间或之后的心律失常。临床表现不一,从心悸、头晕、晕厥、心绞痛、急性心肌梗死和充血性心力衰竭,甚至到心脏性猝死。运动性心律失常可见于心肌缺血,如患有动脉粥样硬化性心脏病以及患有原发性或继发性心肌病的患者。然而,也可能发生在似乎健康的个体。在后一组人群中,运动性心律失常可以是良性的,但也可以是获得性(如药物诱发)或先天性(如先天性长QT综合征或致心律失常性右室发育不良)心电活动或结构的异常而呈恶性。这种潜在病理生理学机制的复杂性,使运动性心律失常的诊断和治疗成为临床医学上的…
