为高效鉴定食用油脂加工厂污水处理过程的气味组成，采用感官检验以臭阈值量化不同处理工序污水的臭味浓度，并采用气相色谱-离子迁移谱法（GC-IMS）对其挥发性化合物进行分析，并对鉴定出的挥发性化合物进行指纹图谱和主成分分析。结果表明：污水经过处理臭阈值明显降低；GC-IMS鉴定出43种化合物，基本均为含氧有机物，包括酮类、醇类、醛类、酯类、酸类及其他类；总体上各处理工序污水挥发性物质总数和臭阈值的变化规律一致；各处理工序挥发性化合物存在一定差异。综上，GC-IMS是分析食用油脂加工厂污水处理过程气味变化的有效方法。 In order to effectively identify odorants in wastewater treatment process in edible oil plant, the odor concentration of wastewater from different treatment processes was quantified by the threshold odor number(TON) through sensory examination, and the volatile organic compounds (VOCs) were identified using gas chromatography-ion mobility spectrometry (GC-IMS) and analysed by fingerprint plot and principal component analysis. The results showed that the TON of wastewater was significantly reduced after treatment. Forty-three compounds were identified by GC-IMS, all of which were basically oxygen-containing organic compounds including ketones, alcohols, aldehydes, esters, acids and others. The change rule of TON of wastewater was overall consistent with volatile compounds among the treatment processes. There was a variation in VOCs′ overallcomposition among the treatment processes. In conclusion, the GC-IMS technique is an efficient method for analyzing the odor variation of wastewater treatment in edible oil plant.

Abstract: Elongated styloid process is the main anatomical abnormality leading to carotid dissection, and the patient with ischemic stroke caused by carotid dissection associated with elongated styloid process was reported here. The patient had a long-standing history of frequent head down and head lift work and CTA with three-dimensional reconstruction showed bilateral elongated styloid processes. Left internal carotid artery dissection due to long-term mechanical injury was the underlying cause of this ischemic stroke, and arterial dissection was repaired well after stenting in the left internal carotid artery. Adequate attention should be paid to ischemic stroke associated with styloid process syndrome to reduce the risk of recurrent stroke.

Objective To observe the clinical effect of Chinese medicine preparations at Shenque and Dazhui acupoints on relieving the symptoms of sleep disorders in patients with laryngocarcinoma. Methods A total of 50 hospitalized patients with laryngocarcinoma and sleep disorders were selected and randomly divided into treatment group (n=25) and control group(n=24, as one case lost to follow-up). In the treatment group, homemade herbal powders (the rhizome of Chinese goldthread and cinnamon) mixed with petroleum jelly and vinegar were applied to Dazhui and Shenque acupoints. In the control group, corn cobs and starch were used to make powder mixed with petroleum jelly and vinegar to make a placebo and then the same operation was performed to apply to the acupoints. The patient sleep quality was measured by using Pittsburgh Sleep Quality Index (PSQI) before treatment, after treatment and during follow-up. The Traditional Chinese Medicine (TCM) syndrome score of insomnia was compared between two groups, and the complication was recorded during treatment and follow-up. Results The total PSQI score decreased in both group after intervention and during follow-up, and the treatment group showed a significant reduction in total PSQI score compared with the control group (P＜0. 05). The TCM syndrome score decreased in both group after intervention, and TCM syndrome score in the treatment group was lower than that in the control group (P＜0. 05). One person in the treatment group experienced skin reaction. Conclusion Homemade Chinese medicine preparations applied externally to acupuncture points have relieved the symptoms of sleep disorders and improved the sleep quality of patients with laryngocarcinoma, which is worthy of promotion and application.

The results showed that both the waxes exhibited stable oleogels with low frequency dependence at the dosage of 5%. Candelilla wax had stronger thermal stability and apparent viscosity, while Japan lacquer wax had higher thixotropic recovery. Thermal properties further comfirmed that the difference of oleogels capacity was related to the composition of waxes. At the microscopic level, candelilla wax oleogels and Japan lacquer wax oleogels presented cluster and needle-like crystal morphologies, respectively. The crystal polymorph of candelilla wax was β′, while the crystal arrangement of Japan lacquer wax changed in the process of forming oleogel, and its crystal polymorph turned from β′ to β. Japan lacquer wax had special crystalline properties different from other high-melting point waxes, and had potential application value in the development of plastic fat replacement.
