目的:探讨腔镜下治疗早期分化型甲状腺癌可行性及临床应用价值。
方法:回顾性分析2010年1月—2013年6月收治的75例早期分化型甲状腺癌患者临床资料,其中15例患者行全腔镜甲状腺切除术(腔镜手术组),60例患者行传统手术(传统手术组),所有患者均至少行患侧腺叶及峡部切除加中央区淋巴结清扫。比较两组的主要各项临床指标及术后美容效果。
结果:15例腔镜手术患者均获得成功,无中转开放手术病例,无术后大量出血患者。腔镜手术组手术时间略长于传统手术组,但差异无统计学意义(P=0.059);两组均无术后低钙血症及声音嘶哑并发症,两组术中出血量、术后引流量、住院天数、中央淋巴结清扫数差异均无统计学意义(均P>0.05)。两组患者术后随访6~36个月,均无复发病例,腔镜手术组患者的手术瘢痕小且隐蔽,美容效果明显好于传统手术组。
结论:腔镜下治疗早期分化型甲状腺癌是安全可行,有良好美容效果。 相似文献

目的 探讨以戊二醛为交联剂的血红蛋白类氧载体(HBOCs)的聚合工艺匹配条件的优化研究,进一步降低终产品的平均分子质量和超大分子含量,提高聚合血红蛋白的有效转化率.方法 在前期对人胎盘血红蛋白与戊二醛交联的单因素影响水平的研究基础上,选取戊二醛的加样速度、血红蛋白的质量浓度和戊二醛与血红蛋白的摩尔比3个因素做正交试验以优化血红蛋白聚合工艺的匹配条件.结果 戊二醛与血红蛋白的摩尔比对聚合血红蛋白分子质量分布的影响最大,其次是血红蛋白的质量浓度,最后为戊二醛的加样速度.对平均分子质量的影响分析,不同的戊二醛与血红蛋白摩尔比条件下的平均分子质量间的差异均具有统计学意义(P<0.05),而不同的血红蛋白质量浓度和戊二醛的加样速度条件下的平均分子质量间的差异均无统计学意义(P>0.05);对有效转化率的影响分析,不同的戊二醛与血红蛋白摩尔比和不同的血红蛋白质量浓度条件下的有效转化率间的差异均具有统计学意义(P<0.05),不同的戊二醛加样速度条件下的有效转化率间的差异均无统计学意义(P>0.05);对超大分子含量的影响分析,不同的戊二醛与血红蛋白摩尔比条件下的超大分子含量间的差异均具有统计学意义(P<0.05),不同血红蛋白的质量浓度和戊二醛的加样速度条件下超大分子含量间的差异均无统计学意义(P>0.05).结论 通过以上实验分析,优化确定了血红蛋白聚合工艺的最佳匹配条件. 相似文献

Enhanced Photo-Fenton Activity of SnO2/α-Fe2O3 Composites Prepared by a Two-Step Solvothermal Method
Pinghua Li Xuye Zhuang Jiahuan Xu Liuxia Ruan Yangfan Jiang Jiaxin Lin Xianmin Zhang 《Materials》2022,15(5)
The x-SnO2/α-Fe2O3 (x = 0.04, 0.07, and 0.1) heterogeneous composites were successfully prepared via a two-step solvothermal method. These composites were systematically characterized by the X-ray diffraction technique, field emission scanning electron microscopy, an energy dispersive spectrometer, X-ray photoelectron spectroscopy and a UV–visible spectrometer. It was found that SnO2 nanoparticles were uniformly decorated on the surface of α-Fe2O3 particles in these heterogeneous composites. A comparative study of methylene blue (MB) photodegradation by α-Fe2O3 and x-SnO2/α-Fe2O3 composites was carried out. All x-SnO2/α-Fe2O3 composites showed higher MB photodegradation efficiency than α-Fe2O3. When x = 0.07, the MB photodegradation efficiency can reach 97% in 60 min. Meanwhile, the first-order kinetic studies demonstrated that the optimal rate constant of 0.07-SnO2/α-Fe2O3 composite was 0.0537 min−1, while that of pure α-Fe2O3 was only 0.0191 min−1. The catalytic mechanism of MB photodegradation by SnO2/α-Fe2O3 was examined. The SnO2 can act as a sink and help the effective transfer of photo-generated electrons for decomposing hydrogen peroxide (H2O2) into active radicals. This work can provide a new insight into the catalytic mechanism of the photo-Fenton process. 相似文献

As a key element during HBV replication, a nucleocapsid is considered a promising target for the treatment of chronic hepatitis B. The present study aimed to identify small molecules as novel capsid assembly modulators with antiviral activity. Structure-based virtual screening of an integrated compound library led to the identification of several types of HBV inhibitors. Among these inhibitors, N-sulfonylpiperidine-3-carboxamides (SPCs) potently reduced the amount of secreted HBV DNA. Through structure–activity relationship studies, we identified an SPC derivative, namely, C-39, which exhibited the highest antiviral activity without causing cytotoxicity. Mechanism studies showed that C-39 dose-dependently inhibited the formation of HBV capsid, synthesis of cccDNA, e antigen (HBeAg), viral pregenomic RNA (pgRNA), and HBV DNA levels, thereby restraining HBV replication. In summary, SPCs represent a new class of capsid assembly modulators. Further optimization of SPCs is expected to obtain new antiviral drugs against HBV infection. 相似文献

Rationale:Hemidiaphragmatic paralysis (HDP) is a frequent complication of the brachial plexus block, caused by unintentional blockade of ipsilateral phrenic nerve. HDP did not rise enough alarm and attention to most anesthesiologists, because most patients with no coexisting comorbid diseases are asymptomatic and able to tolerate it. However, it may cause severe respiratory complication for patients with preexisting compromised cardiorespiratory function.Patient concerns:A 67-year-old woman with morbidly obesity was planned to receive opening reduction and internal fixation of right humeral shaft fracture under regional anesthesia considering less respiratory and cardiovascular system interference compared with general anesthesia.Diagnoses:After ultrasound guided supraclavicular brachial plexus block, the patient developed severe hypoxia and hypercapnia.Unintentional block of phrenic nerve and diaphragm paralysis was diagnosed by diaphragm ultrasound, which was considered as the main reason of severe hypoxia.Interventions:It led to a conversion from regional anesthesia to general anesthesia with endotracheal intubation for patient''s safety and smooth operation.Outcomes:The unintentional phrenic nerve block leads to a prolonged ventilation time, length of stay in intensive care unit and length of stay in hospital.Lessons:This case report highlights the risk of diaphragm paralysis in morbidly obese patients. Though new diaphragm sparing brachial plexus block (BPB) methods were developed intended to reduce the risk of HDP, no approaches could absolutely spare phrenic nerve involvement. Therefore, clinicians should always consider the risk of HDP associated with BPBs. For each individual, a detailed preoperative evaluation and sufficient preparation are paramount to avoid serious complications. 相似文献
