Reconstruction of palatomaxillary defects following cancer ablation with temporalis muscle flap in medically compromised patients: a 15-year single institutional experience

Objectives

Successful reconstruction of palatomaxillary defects following cancer ablation represents a formidable challenge for surgeons to achieve consistently favorable outcomes. The purpose of this article is to present our experience in oncologic palatomaxillary repair with temporalis muscle flap (TMF) for medically compromised patients who are not ideal candidates for microvascular reconstruction at a Chinese tertiary referral hospital over a 15-year period (1998–2012).

Method

A retrospective chart review was performed to identify patients with compromised medical conditions who underwent oncologic palatomaxillary reconstruction using TMF. Patients’ demographics, clinicopathological variables, and surgical techniques were presented. Postoperative functional and aesthetic outcomes were assessed by measurements and patients self-evaluations.

Results

Sixty-nine TMFs were successfully harvested and used for immediate oncologic palatomaxillary reconstruction in 67 patients (31 males and 36 females, mean age 60.4 years) with diverse primary malignancies. These patients’ co-morbidities included systemic diseases, preoperative chemotherapy/radiotherapy, and elder over 65 years which precluded the ideal utility of free flaps. Fifty-one patients remained alive without disease, while nine had recurrences/metastases and seven died during the follow-up (0.5–10.4 years, mean 3.7 years). All flaps survived with only partial necroses in four cases. Complications and donor-site morbidities were minimal with five transient facial paralysis and four mild diplopia and enophthalmos. Unrestricted diet and mouth opening, intelligible speech, and satisfactory temporal aesthetics were obtained in most patients.

Conclusion

The TMF is a reliable, versatile, and alternative option for oncologic palatomaxillary reconstruction with satisfactory functional and aesthetic outcomes and minimal complications, especially when appropriately selected for those medically compromised patients.     

恩度联合顺铂对老年肿瘤患者恶性腹水的疗效

目的 采用腹腔给药的方式观察恩度联合顺铂对老年人难治性恶性腹水的临床疗效,生活质量的改善及免疫力的影响。方法 收集经病理确诊的恶性腹腔积液老年患者64例。持续引流后,对照组：顺铂30 mg腹腔注射d1、d4、d7;21天重复,联合用药组（试验组）：顺铂30 mg +恩度45 mg腹腔注射d1、d4、d7;21天为一疗程。两组均完成2个同期的治疗。通过实体瘤的疗效诊断标准（RECIST）评价两组临床疗效,通过美国国立癌症研究所（NCI）标准评价不良反应;通过心理问卷评估对患者焦虑、抑郁的改善,抽取静脉血,监测治疗前后CD4/CD8水平。 结果 试验组临床有效率高于对照组,显著改善了患者的焦虑及抑郁状态;试验组较对照组并未显著降低CD4/CD8。结论 恩度联合顺铂提高腹水缓解率,未增加明显不良反应;改善焦虑抑郁状态;未降低患者的免疫力。     

Brillouin显微镜测量角膜生物力学性能的研究进展

角膜具有各向异性、非线性和黏弹性等复杂的生物力学性能,随着基础和临床研究的不断深入,生物力学在角膜疾病的诊断和治疗中发挥着越来越重要的作用。离体角膜与在体角膜的力学性能存在显著差异,探索在体测量角膜生物力学的方法对角膜疾病的诊断与治疗有直接的指导意义。目前在体测量的仪器主要有眼反应分析仪和可视化角膜生物力学分析仪,但二...     

Impact of purple sweet potato (Ipomoea batatas L.) polysaccharides on the fecal metabolome in a murine colitis model

Purple sweet potato polysaccharides (PSPP) play an important role in regulating the gut microbiota, modulating intestinal immunity and ameliorating colonic inflammation. In this study, the impact of two PSPPs (PSWP-I and PSAP-I) on the metabolomic profiling of feces from dextran sulfate sodium (DSS)-induced colitis mice was evaluated by ultra-high performance liquid chromatography coupled with triple time-of-flight tandem mass spectrometry (UPLC-Triple-TOF-MS/MS). Results indicated that there were twenty-five metabolites with significant changes and four remarkable metabolic pathways, i.e., cutin, suberine and wax biosynthesis, biosynthesis of unsaturated fatty acids, fatty acid biosynthesis, and steroid hormone biosynthesis. Two key biomarkers of oleic acid and 17-hydroxyprogesterone were screened that responded to PSPPs in colitis mice. The identified metabolites were correlated with the amelioration of intestinal immune function and the modulation of the gut microbiota. Nine pro-inflammatory and eight anti-inflammatory compounds responded to PSPPs, which were related to Bacteroides, norank_f__Clostridiales_vadinBB60_group, unclassified_o__Bacteroidales, Rikenella and Lachnospiraceae_UCG-001. Moreover, PSWP-I and PSAP-I had different regulating effects on intestinal metabolites. Our results revealed a possible metabolomic mechanism of PSPPs to regulate intestinal inflammation function.

Quantitative analysis of chemical constituents in different commercial parts of Notopterygium incisum by HPLC–DAD–MS

Ethnopharmacological relevance

Notopterygium incisum used as an antirheumatic and analgesic medicine for the treatment of rheumatism, headache, cold, etc., is not only a traditional Qiang medicine, but also a traditional Tibetan remedy for thousands of years.

Aim of the study

In order to use this herbal medicine in a more effective way, in the present investigation, we analyzed the main chemical constituents of different commercial parts as well as fibrous roots of Notopterygium incisum.

Materials and methods

All crude Notopterygium incisum samples used in this study were collected in Sichuan province of China. We used HPLC-DAD-MS to analyze quantitatively the main chemical constituents of different commercial parts as well as fibrous roots of Notopterygium incisum.

Results

According to different commercial parts, 10 Notopterygium incisum samples collected from two main production areas have been investigated, and four main constituents have been quantitatively analyzed.

Conclusion

The quality of rhizomes is better than that of main roots. Unexpectedly, the content of two main constituents, notopterol and isoimperaorin, in fibrous roots is higher than any other parts of Notopterygium incisum. This result implied that the fibrous root may also have value, and we should study it to explore its potential.
