Psychosis as a predictor of response to lithium maintenance treatment in bipolar affective disorder

Sixty-six bipolar I lithium clinic patients were studied for a history of psychotic symptoms at some time during the course of their illness. Agreement between different sources of information was calculated, and the patient population was divided into psychotic and non-psychotic subgroups. Probability of remaining well on lithium for the different subgroups was analyzed by the life table method. Psychosis during mania appeared to be associated with especially good early lithium prophylaxis.     

The effect of beta adrenergic blockade on bronchial sensitivity to acetyl-beta-methacholine in normal and allergic rhinitis subjects.

The effect of propranolol inhalation on sensitivity to methacholine inhalation was studied in normal and allergic rhinitis subjects to determine whether beta adrenergic blockade alters sensitivity to mediators in nonasthmatic atopic individuals. A partial beta adrenergic blockade is suggested as being instrumental in asthma. Hay fever patients studied showed similar effects and also developed asthma for the first time.     

母婴同室新生儿感染因素分析

目的：把母婴同室的新生儿感染率控制到最低限度。方法：采用回顾性分析方法,对近两年我院母婴同室新生儿感染情况与过去母婴分室新生儿感染的情况进行对比,分析新生儿感染因素。结果：母婴同室新生儿感染发生率４．４％,比母婴分室新生感染率１０．２８％明显降低。晶龄大于３ｄ的新生儿母婴同室的感染率明显低于母婴分室的感染率,晶龄３ｄ内的新生儿母婴同室与母婴分室无明显差异。结论：母婴同室实行的各项措施比较有效地控制     

农村试点卫生村住宅卫生现状的研究

目的：了解已建成的卫生村住宅卫生现状，为制定《卫生村建设与验收技术规范》提供依据。方法：采用问卷调查与现场测量、测定的方法。结果：被调查的卫生村一般卫生状况基本符合卫生要求，但村内公用基础卫生设施不足。居民宅基地户均面积166．61m^2人均43．17m^2建筑面积户均165．08m^2，人均42．92m^2，使用面积户均136．23m^2,人均35．50m^2。居民居住房间配置基本合理。居室内气温达标率较低，但水平温差和垂直温差符合卫生要求。气湿达标，气流基本符合卫生要求。结论：卫生村住宅卫生现状基本符合卫生学要求，需进一步加强对卫生村规划与建设技术指导。     

Measurement and Control of Surgical Smoke to Enhance Surgical Team Safety

Amid the coronavirus disease 2019 era, concern about the safety of surgical teams related to surgical smoke (SS) is rising. As simple ventilation improvement methods (SVIMs), we replaced 4 of the 8 supply diffusers with a direction-adjustable louver-type, closed 2 of the 4 exhaust grills, and strengthened the sealing of the doorway. Dynamic changes in the concentration of particulate matter (PM) with sizes of < 1.0 μm (PM1.0) were measured using low-cost PM meters (LCPMs) at eight locations in the operating room (OR). SS concentration up to 4 minutes at the location of the surgeon, first assistant, and scrub nurse before and after SVIMs application decreased from 65.4, 38.2, 35.7 µg/m³ to 9.5, 0.1 and 0.7 µg/m³ respectively. A similar decrease was observed in the other 5 locations. SVIMs could effectively control SS and the LCPM was also effective in measuring SS in the OR or other spaces of the hospital.     

Corrosion Protection of Q235 Steel Using Epoxy Coatings Loaded with Calcium Carbonate Microparticles Modified by Sodium Lignosulfonate in Simulated Concrete Pore Solutions

In this study, calcium carbonate (CaCO₃) microparticles having pH-sensitive properties were loaded with sodium lignosulfonate (SLS), a corrosion inhibitor. Scanning electron microscope (SEM), UV–VIS spectrophotometer (UV-vis), X-ray diffraction (XRD), and attenuated total reflection-Fourier-transform infrared spectroscopy (ATR-FTIR) were applied to evaluate the properties of the synthetic microparticles. This material could lead to the release of corrosion inhibitor under different pH conditions of the aqueous media. However, the extent of release of the corrosion inhibitor in the acidic media was higher, leading to enhanced shielding effect of the Q235 steel. These microparticles can serve as anti-corrosion additive for epoxy resin-coated Q235 steel. Electrochemical experiments were used to assess the anti-corrosive ability of the epoxy coatings in simulated concrete pore (SCP) solution, confirming the superior corrosion inhibition of the epoxy coating via incorporation of 5 wt % calcium carbonate microparticles loaded with SLS (SLS/CaCO₃). The physical properties of coating specimens were characterized by water absorption, contact angle, adhesion, and pencil hardness mechanical tests.
