基于寒区发病特点的龙江医家血液病中医辨治思维与实践＊

中医临床思维在诊疗中扮演着重要角色，为立法之纲纪，治病之根本。今之血液系统疾病变化趋于复杂，临床辨治思维是中医血液病诊治的关键所在。本文基于寒区发病特点、龙江地域气候与人民生活特征，总结以前辈高仲山、华廷芳先生，国家级名中医孙伟正教授为代表的龙江名医血液病诊疗特色经验，通过“因实、因虚致病”病机，以“三因制宜”为基础，系统阐述了“实者以决、结者以散、虚者宜补、劳者宜温”的血液病中医辨治思维及其实践，为寒区血液疾病的中医诊治提供了治法方向。     

运用六经辨证治疗子嗽探析

妊娠期间,咳嗽不已,称"妊娠咳嗽",亦称"子嗽",孕妇咳嗽日久未见好转,咳嗽胸痛甚则咳而呕吐,或咳嗽剧烈或久咳不愈,可损伤胎气,导致堕胎、小产。笔者运用六经辨证治疗外感型中表寒里热证子嗽,认为此类患者病在太阳阳明,属于寒热错杂之表寒里热,采用《伤寒论》中方证麻杏甘石汤合止嗽散,使热从外泄,宣发卫气,散寒不助热、解表不伤正,故辨证论治取得了显著的疗效。同时子嗽治疗还需注意健脾固肾安胎,应将顾护胎元贯穿治疗妊娠咳嗽的始终。     

基于Bark域的电子耳蜗频带划分分析和拟合研究

目前电子耳蜗主流的言语处理策略是基于滤波器组的言语处理算法，该算法通过分频带进行信号处理并把参数传递到对应的电极上。电子耳蜗滤波器组的频带划分不是等分的，而是按一定规律进行并且符合人耳听觉特性的，其中，Bark域的频带划分是重要的参考。本研究基于Bark域的电子耳蜗频带划分方法，探讨Bark域频带划分的特性并结合目前的电子耳蜗滤波器组的频带划分进行分析，进而探讨频带划分中的曲线拟合方法，为电子耳蜗滤波器组中的频带划分提供重要的方法和参数。     

新产程模式下剖宫产和产钳术对持续性枕后位难产孕妇分娩结局的评估

目的：探索新产程模式下剖宫产和产钳术对持续性枕后位难产孕妇分娩结局的评估。方法:收集2017年至2020年间于浙江省湖州市妇幼保健院收住入院的103例持续性枕后位难产孕妇, 其中以产钳分娩的60例孕妇为研究组，53例以剖宫产术分娩的孕妇为对照组，评估其分娩结局，分析两种分娩方式对孕产妇的影响。采用χ2 检验比较剖宫产及产钳分娩两组的新生儿窒息、产后出血、产时、产后感染、软产道裂伤（包括会阴III度裂伤、阴道裂伤、宫颈裂伤）、切口预后不良的差异。结果：研究组产后出血、产时发热、产后发热发生率[分别为1.66%（1/60）、1.66%（1/60）、3.33%(2/60），χ2 值分别为（4.514 和5.698、4.826，P值分别为 0.040 和 0.020、0.030）]，明显低于对照组[分别为11.32%（6/53）、13.20%（7/53）、15.09%(8/53）]，但是研究组会阴III度裂伤、宫颈裂伤、阴道裂伤、发生率为分别为[15.00%（9/60）、13.33%（8/60））、（11.66%（7/60）），明显高于对照组（1.88%（1/53）、1.88%（1/53）、3.77%（2/53））]，差异有统计学意义（P值均＜0.05）。但研究组的新生儿窒息发生率及切口预后不良的比例分别为[5（8.33%）、4（6.66%）]，略低于对照组[（6（11.32%）、4（7.54%）]，差异无统计学意义（χ2值分别为0.286、0.233，P 值均＞0.05）。结论：新产程标准下持续性枕后位难产孕妇选择产钳分娩可明显降低产时、产后感染及产后出血的发生率，但软产道裂伤发生率较高，差异有统计学意义。所以持续性枕后位难产孕妇选择产钳分娩是相对比较安全的分娩方式，但同时需要注意软产道裂伤的发生。

Temperature Measurement by Sublimation Rate as a Process Analytical Technology Tool in Lyophilization

Product temperature (T_b) and drying time constitute critical material attributes and process parameters in the lyophilization process and especially during the primary drying stage. In the study, we performed a temperature measurement by the sublimation rate (TMbySR) to monitor the T_b value and determine the end point of primary drying. First, the water vapor transfer resistance coefficient through the main pipe from the chamber to the condenser (C_r) was estimated via the water sublimation test. The use of C_r value made it possible to obtain the time course of T_b from the measurement of pressure at the drying chamber and at the condenser. Second, a Flomoxef sodium bulk solution was lyophilized by using the TMbySR system. The outcome was satisfactory when compared with that obtained via conventional sensors. The same was applicable for the determination of the end point of primary drying. A laboratory-scale application of the TMbySR system was evidenced via the experiment using 220-, 440-, and 660-vial scales of lyophilization. The outcome was not dependent on the loading amount. Thus, the results confirmed that the TMbySR system is a promising tool in laboratory scale.     

EEG source estimation in a rare patient with cold‐induced reflex epilepsy

Temperature‐related reflex epilepsy most often takes the form of hot water epilepsy, but very rarely, reflex epilepsy is related to cold temperature. We report a 70‐year‐old male who had seizures triggered by cold sensations in the body. Four antiepileptic drugs were taken during the drug treatment, and oxcarbazepine was the most effective at stopping the seizures. We implemented clinical seizure induction and obtained EEG data from an interictal period and two complete ictal periods. Source estimation was performed to identify and map the primary sources involved in the seizures on the cortical level. We found that β rhythm appeared on the prefrontal lobes during the whole ictal period. The low‐frequency slow δ and θ rhythms, especially the δ rhythm, appeared in the occipital lobe in the early ictal stage and propagated to the right temporal lobe in the mid‐late ictal stage. The prefrontal lobe and right temporal lobe were mainly involved in the generation and propagation of the epileptic activities. This study provides a valuable reference for clinical drug therapy and provides insights into the characteristics of the brain activities involved in cold‐induced reflex epilepsy.

The Influence of the Common Cold on Self-Rated Health: A Population-Based Study

ObjectiveStudies on the association between self-rated health and acute conditions are sparse. The aim of this study was to examine whether individuals respond to acute conditions (such as the common cold) in health ratings as well as the effect of chronic conditions (using the Charlson comorbidity score) on self-rated health.MethodsThe national representative survey data was linked with the claims data from the Taiwan National Health Insurance for 13,723 adults ≥ 18 years. Ordered logistic regressions with fractional polynomials were estimated to determine the relationship between the frequency of common cold episodes and the Charlson comorbidity score on self-rated health. The interactions between these two variables and the baseline age were tested.ResultsSelf-rated health worsens with the increased frequency of both common cold episodes and the Charlson comorbidity score. Both variables have a non-linear relationship with self-rated health. Younger individuals put heavier weight on acute health conditions than their older counterparts.ConclusionIndividuals respond to questions regarding their self-rated health based on their acute health condition along with chronic condition. Thus the information on self-rated health depends on the timing the information is collected, and whether at that time the individual experienced acute health conditions or not.
