柳宝诒托法治伏温析要

晚清名医柳氏宝诒擅治温病,尤精於伏气温病的研究。其采撷名贤著述,参以己见,对伏温详加注述,并著《温热逢源》、《柳宝诒医案》等书。其论理细腻,用药精究,颇为近代医家推崇。故本文试就柳氏运用托法治疗伏气温病的经验析其要点,以飨同道。

系统性红斑狼疮从伏温认知

本文通过对系统性红斑狼疮的临床表现特点进行分析,提出系统性红斑狼疮属伏温的观点。并具体指出是邪伏于少阴,病发于厥阴。故治疗上主张:疾病初起即宜直清里热。知其传变、明晰治疗,尤其强调要注意始终护肾。相对于以往对本病的分型论治,作者首次从伏温角度对系统性红斑狼疮作新的认识,为中医全面、深入地认识系统性红斑狼疮提供了一个新的思路。

基于“伏温”探讨“透邪扶正”法治疗活动期溃疡性结肠炎

文章结合伏温理论和溃疡性结肠炎(ulcerative colitis,UC)的发病特点,提出了UC可从伏温论治的观点。脾虚失运、湿热蛰伏是该病的基本病机,湿热外达阳明肠腑,与气血糟粕相搏结是活动期UC的病机特点。透邪扶正是治疗该病的根本大法,在临床中应该根据患者症状在透邪、解毒、扶正等治法中进行权衡,以取得最佳的临床疗效。在伏温理论下,从“透邪扶正”探讨该病论治可能为UC临床诊疗提供新的思路。

基于邪伏膜原理论探讨伏温疫之防治

我国古代在应对疫病的过程中形成了诸多理论,积累了许多行之有效的方法。文章拟以新型冠状病毒感染(COVID-19)为契机,通过观察分析感染人体后的症状表现,拟用“伏温疫”这一病名概括这一类具有潜伏性、传染性且具有热毒性的疫病,并基于邪伏膜原的基本理论,通过阐述伏温疫的发病过程及病机,进一步探讨伏温疫的预防及治疗方法。文章论述了温邪起病本与六淫物候无关,提出注重温疫的首末两端诊治,以未病远疫、邪伏膜原和邪留膜原3个方面论述避、溃、搜三法,丰富了疫病防治的理论内容,更为后世医家在防治此类疫病的过程中提供些许经验。

《黄帝内经》伏邪理论探析

伏邪是中医病因理论体系中一类重要的概念,很多外感病及内伤杂病的发生发展与伏邪密不可分,因此认清伏邪对当今临床诸多疾病的诊断与治疗均具有重要的指导性意义。《黄帝内经》(以下简称《内经》)作为伏邪理论的源头,虽未对伏邪命名,但已认识到某些“伏邪现象”,其相关论述也初备伏邪理论基本框架。本文通过梳理《内经》中伏邪的相关论述,还原伏邪理论最初原貌,得出在《内经》中已认识到“风、雨、寒、暑皆可留止”,乘虚而入成为伏邪,其可伏留于脏腑、经络、肌腠、筋脉、骨髓等各个部位,郁滞气血,耗伤正气,日久可致虚劳积聚。

Flowering Characteristics of Japonica Rice Male Sterile Lines Adaptive to High Temperature and Summer Drought

[Objective] This study was conducted to screen japonica rice male sterile lines with good flowering characteristics under high temperature and summer drought. [Method] The flowering habits of 23 japonica male sterile lines, such as flowering peak, single-panicle flowering duration, single-plant flowering duration, en- closed glume rate, glume-opening angle, the distance between glumes, stigma exer- tion rate and sigma vitality, were compared with II-32A as a control under above weather condition. [Result] The flowering characteristics had significant difference a- mong the tested rice lines. Compared with the control, three japonica rice male ster- ile lines 35478A, 35489A and 35502A had better flowering traits, such as earlier flowering peak, longer single-panicle flowering duration, longer single-plant flowering duration, lower rate of enclosed glumes, larger glume angle and larger distance be- tween glumes. 35478A performed its flowering peak from 10：00-11：00 am, 1.5 h earlier than the control; 35489A exhibited higher stigma exertion rate, up to 76.23%; and 35502A had higher stigma vitality, up to 84.68%, which kept longer time than that of the CK. [Conclusion] The results will provide high-quality resources for the breeding of new japonica rice varieties with high-yield and high-temperature toler- ance.

Electrodeposition Behavior of Nickel from a Low Temperature Urea-molten Salt

The electrodeposition behavior of nickel at glassy carbon(GC)and stainless steel(SS)electrodes in low temperature urea-acetamide-NaBr-KBr melt was investigated using cyclic voltammetry,chrono-amperometric current-time transients and scanning electron microscopy.Cyclic voltammograms and dimensionless chronoamperometric current-time transients analysis show that the electrodeposition of nickel is an irreversible process and proceeds via three-dimensional progressive nucleation with diffusion-controlled growth on both GC and SS substrates.Scanning electron microscopic analysis indicates the nickel deposits obtained on SS electrode are generally uniform,dense,and adherent to the substrate with rounded crystallites in the nanometer size regime.It is also found that the crystal structure of the electrodeposited nickel is independent on the deposition potential.The nickel deposits produced from the melt at higher cathodic potential exhibit larger grain size.

Evaluation of Heat and Current Characteristics of Bypass Diodes for Fault Detection in Photovoltaic Module

In recent years, PV （photovoltaic） systems have been installed rapidly around the world. However, there is often a delay in the practical application of fault detection in PV systems. In this study, the temperature of BD （bypass diodes） mounted on PV modules was measured for simple and practical fault detection. The temperature of the BD of Module 31 was higher than other modules and a large current passed through one of the BDs. Measuring BD temperatures is easier than other conventional methods of fault detection. From the results of the rise in BD temperature under dark conditions, the increase in temperature increased linearly with increasing current flow. There is a proportional relationship between heat generated and the increasing temperature of the terminal box. The experimental results about surface temperature of the junction box in actual system operation suggested that the electric current through a BD in a terminal box can be known by measuring the surface temperature of the terminal box for PV module fault detection without a system shutdown. Moreover, we tried to evaluate temperature distribution of a terminal box using heat conduction equations. The evaluated results agreed well with the measured results.

Potentialities of Renewable Energy in Victoria, Australia

In utility power system, electricity demand is being covered largely by fossil fueled power generation, which contributes high level of GHG （greenhouse gas） emission and causes global warming worldwide. In order to reduce GHG emission level, most of the countries in the world targeting towards green energy that is power generation from RE （renewable energy） sources. In this paper, it is considered to study prospects of RE sources in particular, solar and wind in Victoria State which are abundant as compared to other sources of renewable. The wind and solar energy feasibility study and sensitivity analysis has been done for Victoria with the aid of HOMER （hybrid optimization model of electric renewable） simulation software. From the study, it has clearly evicted that wind energy combinational HPS （hybrid power system） has more contribution, and high potential than solar PV （photovoltaic） systems for a particular location. This study also investigates the influences of energy storage in the proposed HPS.

Calculation of natural circulation under heaving motion

Wide validation of self-developed program of natural circulation under oceanic conditions has been conducted compared with experimental data of inclination,zero-power condition and hot-state condition.Experiments were performed on a full-scale,whole parameterization natural circulation loop designed with reference to 5 MW experimental low temperature nuclear heating reactor(NHR)of Tsinghua University.Investigation of natural circulation and parameter effect under heaving motion was carried out using the program and comparison of heaving,inclination and rolling on natural circulation respectively to reveal the influence mechanism.Results indicate that:(1)significant influence of heaving motion on natural circulation was observed,and heaving motion with high level of strength and long cycle would lead to severe flow fluctuation;(2)slight effect was caused by short cycle heaving motion which was completely different from long cycle heaving motion;(3)comprehensive action of alternating force and flow density distribution would result in natural circulation under heaving motion;(4)most severe accidents maybe result from the long cycle heaving motion rather than inclination and rolling motion.Investigation of influence of heaving motion on natural circulation could have important reference significance in the optimization design of nuclear reactors.

Efficient solar fuel production with a high-pressure CO_(2)-captured liquid feed

We demonstrated an efficient solar photovoltaic-powered electrochemical CO_(2) reduction device with a high-pressure CO_(2)-captured liquid feed.In an“air-to-barrel”picture,this device holds promise to avoid both high-temperature gaseous CO_(2) regeneration and high energy-cost gas product separation steps,while these steps are necessary for devices with a gaseous CO_(2) feed.To date,solar fuel production with a CO_(2)-saturated liquid feed suffers from high over-potential to suppress the hydrogen evolution reaction and consequently,low solar-to-chemical(STC)energy conversion efficiency.Here,we presented a distinct high-pressure operando strategy,i.e.,we took extra advantage of the high pressure in catalyst synthesis besides in the period of the CO_(2) reduction reaction(CO_(2)RR).The power of this strategy was demonstrated by a proof-of-concept device in which a representative copper catalyst was first synthesized in operando in a high-pressure(50 bar)CO_(2)-saturated KHCO3 solution,and then this high-pressure CO_(2)-captured liquid was converted to solar fuel using the operando synthesized Cu catalyst.This Cu catalyst achieved 95%CO_(2)RR selectivity at the recorded low potential of−0.3 V vs.RHE enabled by the combination of operando facet engineering and oxide derivation.Furthermore,this device achieved a record-high STC efficiency of 21.6%under outdoor illumination,superior to other CO_(2)-saturated liquid-fed devices,and compared favorably to gaseous CO_(2)-fed devices.
