Killing Effect of Mixed Fumigation of Phosphine and Carbon Dioxide on Eggs of Lasioderma serricorne F.

[Objective] This study aimed to investigate the killing effect of mixed fumi- gation of phosphine and carbon dioxide on eggs of Lasioderma serricorne F. [Method] The outside-storage phosphine generator was placed in a tabernacled smoke box, and the mortality rates of L. serricome F. eggs in the smoke box under conditions of different aluminium phosphide usage amount and different fumigation time were studied. In addition, the times needed by tabernacle and smoke box cen- ter to reach the phosphine concentration peak were recorded. [Result] The optimum conditions for killing the eggs of L. serricorne were as follows： temperature of （27± 2） ℃, relatively humidity of （45±5）%, aluminium phosphide usage amount of 1.5 g/m3 and effective exposure time of 96 h. The killing effect of mixed fumigation of phos- phine and carbon dioxide was increased with the extension of fumigation time. The increased usage amount of aluminium phosphide showed no significant effect on killing effect. The tabernacle space and smoke box center all required relatively short time to reach the phosphine concentration peak. If the tabernacle had a good airtightness, the overall fumigation time could be shortened. [Conclusion] The fumi- gation method is reliable, and it can be used for the control of L. serricorne F. in tobacco storage.

Impact of Soil Fumigation Practices on Soil Nematodes and Microbial Biomass

This study was designed to understand the impact of methyl bromide (MB) (CH3Br) and its alternatives on both free-living and root-knot nematodes in the soil. A randomized complete block experiment with six treatments and 4 replicates (each replicate in a separate greenhouse) was established in Qingzhou, Shandong Province, China. In addition to MB and untreated control (CK) treatments there were four alternative soil fumigation practices including MB+virtually impermeable films (VIF), metam sodium (MS), MS +VIF and soil solarization combined with selected biological control agents (SS+BCA). Two tomato (Lycopersicum esculentum Mill.) cultivars, cv. Maofen-802 from the Xian Institute of Vegetable Science, China, and cv. AF179 Brillante from the Israeli Hazera Quality Seeds, were selected as test crops. The results indicated that Rhabditidae was the most dominant population with percentage abundance as high as 85% of the total number of identified free-living nematodes, followed by that of Cephalobidae. Methyl bromide and its alternatives except for the non-chemical SS+BCA treatment controlled the target pest, root-knot nematodes. Also, the impact of the three chemical alternatives on free-living nematode number and functional group abundance was similar to the impact associated with a typical methyl bromide application. Chemical fumigation practices, especially that with MB, significantly reduced the number of nematodes in the soil and simultaneously significantly reduced the number of nematode genera thereby reducing nematode diversity. All the four soil chemical fumigation activities decreased soil microbial biomass and had an obvious initial impact on microorganism biomass. Furthermore, both plant-parasitic and fungivore nematodes were positively correlated with soil microbial biomass.

Evaluation of Vaporized Hydrogen Peroxide Fumigation as a Method for the Bio-decontamination of the High Efficiency Particulate Air Filter Unit

Objective To evaluate the performance of vaporized hydrogen peroxide （VHP） for the bio-decontamination of the high efficiency particulate air （HEPA） filter unit. Methods Self-made or commercially available bioindicators were placed at designated locations in the HEPA filter unit under VHP fumigation. The spores on coupons were then extracted by 0.5 h submergence in eluent followed by 200- time violent knocks. Results Due to the presence of HEPA filter in the box, spore recovery from coupons placed at the bottom of the filter downstream was significantly higher than that from coupons placed at the other locations. The gap of decontamination efficiency between the top and the bottom of the filter downstream became narrower with the exposure time extended. The decontamination efficiency of the bottom of the filter downstream only improved gently with the injection rate of H202 increased and the decontamination efficiency decreased instead when the injection rate exceeded 2.5 g/min. The commercially available bioindicators were competent to indicate the disinfection efficiency of VHP for the HEPA filter unit. Conclusion The HEPA filter unit is more difficult than common enclosure to decontaminate using VHP fumigation. Complete decontamination can be achieved by extending fumigation time. VHP fumigation can be applied for in-situ biodecontamination of the HEPA filter unit as an alternative method to formaldehyde fumigation.

Efficacy of combining traditional Chinese medicine fumigation with Western medicine for diabetic peripheral neuropathy:A systematic review and meta-analysis

Objective:A systematic review and meta-analysis was conducted to evaluate the effectiveness of supplementing Western medicine with Traditional Chinese medicine(TCM)fumigation in patients with diabetic peripheral neuropathy.Methods:The China Biomedical Literature,Chinese full-text periodical,China National Knowledge Infrastructure,WanFang,PubMed,EMbase,and Cochrane Library databases were searched for relevant randomized controlled trials published from inception through May 2015.The methodological quality of eligible studies was evaluated using the Cochrane Risk Bias Assessment tool,and summarized effects were calculated using Reviewer Manager 5.1 software.Subgroup analysis was conducted based on the duration of intervention.Results:The initial search identified 312 relevant studies,of which 40 randomized controlled trials involving 3497 patients were eligible for analysis.The results indicated that TCM fumigation significantly improved the curative effects[risk ratio(RR)=1.34,95%CI(confidence interval):1.29e1.39],common peroneal motor nerve conduction velocity[standard mean difference(SMD)=2.93,95%CI:2.26e3.61],common peroneal sensory nerve conduction velocity(SMD=2.23,95%CI:1.46e3.01),and plasma viscosity(SMD=1.02,95%CI:1.35e0.69)compared to Western medicine alone(all p<0.01).A subgroup analysis indicated that the curative effects were significant after 15 days(RR=1.31,95%CI:1.21e1.42),30 days(RR=1.33,95%CI:1.26e1.40),and 60 days(RR=1.50,95%CI:1.32e1.71)of combined treatment(all p<0.01).

Nitrogen Dioxide Fumigation for Microbial Control on Unshelled Peanuts*

Stored peanuts often need treatments to control microbial infections as well as insects to maintain postharvest quality. Nitric oxide (NO) is a recently discovered fumigant for postharvest pest control. NO fumigation must be conducted under ultralow oxygen condition to preserve NO and always contains NO2 due to NO reaction with oxygen and NO2 has antimicrobial property. Therefore, NO fumigation has potential to control both pests and pathogens. In this study, we evaluated antimicrobial effects of NO2 fumigation on unpasteurized unshelled peanuts. Peanuts were fumigated with 0.3%, 1.0%, and 3.0% NO2 for three days at 25˚C by injecting NO gas into glass jars to react with O2 in the atmosphere. After fumigation, wash-off microbial samples were collected from intact peanut samples and, then, cracked open peanut samples with non-selective tryptic soy broth medium. The wash-off samples were then diluted with both the non-selective medium and a fungal-selective potato dextrose broth medium and were tested on GreenLight™ rapid enumeration test based on oxygen depletion on culture medium. All three NO2 fumigation treatments showed significant antibacterial and antifungal effects on intact peanuts as well as on cracked peanuts with complete inhibition with 3.0% NO2. Fumigation did not have obvious effects on appearance of skinned peanut kernels. These results suggested that NO2 fumigation has potential to control microbes on stored products, and NO fumigation with the combination of NO and NO2 has potential to control both insects and microbes on stored products.

Effects of Nitric Oxide Fumigation on Mortality of Light Brown Apple Moth, <i>Epiphyas postvittana</i>(Lepidoptera: Tortricidae)*

Light brown apple moth, Epiphyas postvittana, is a quarantine pest in most countries and has established in California and, therefore, has potential to affect export of fresh products from infested areas. There is currently lack of effective treatment especially against eggs. Nitric oxide is a recently discovered fumigant for postharvest pest control and is evaluated in laboratory fumigations to determine its efficacy against different life stages of this pest. Small scale fumigations with nitric oxide at 1.0%, 2.0%, 3.0%, and 5.0% concentrations were conducted under ultralow oxygen conditions at 2˚C against larvae, pupae, and eggs of light brown apple moth. Treatment times ranged from 4 to 24 h depending on nitric oxide concentration and life stage. Complete control of larvae and pupae was achieved in 8 h fumigation with 2.0% NO. Eggs were successfully controlled in 6, 12, and 24 h fumigations with 5.0%, 3.0%, and 2.0% NO respectively. The study demonstrated that nitric oxide fumigation was effective against all life stages of light brown apple moth and, therefore, has potential to be an alternative treatment to methyl bromide fumigation for postharvest control of light brown apple moth.

Efficacy of TCM Fumigation Using Dampness-and-cold-dispelling Formula Combined with Methotrexate and Leflunomide Treating Rheumatoid Arthritis with Cold-dampness Bi Syndrome

Background:Rheumatoid arthritis(RA),a chronic autoimmune disease,has a high incidence and disability rate,causing patients significant discomfort.Although several medicines can be effective,they are also associated with significant adverse effects.In contrast,fumigation as one of the most often used traditional Chinese medicine(TCM)external therapy has shown both efficacy and safety with less side effect.In light of this,we comple-ment western medicine treatment with TCM fumigation therapy to improve patients’clinical efficacy,alleviate symptoms,and improve prognosis.Objective:To investigate the therapeutic effect of TCM fumigation and modern medicine combined therapy in treating RA patients with cold-dampness Bi syndrome.Methods:A single-center,randomized,controlled study was designed.From January 2022 to December 2022,a total of 60 RA patients with cold-dampness Bi syndrome were enrolled in the study.The control group(30 cases)received conventional modern medicine treatment with methotrexate for 4 weeks,while the observation group(30 cases)for 4 weeks received a combination of TCM fumigation treatment and conventional modern medicine.The effects of the two groups were comprehensively compared,including the changes in TCM symptom scores and laboratory indicators,as well as the use of visual analogue scale(VAS)and health status rating scale(HAQ)before and after treatment.Results:The total effective rate of the observation group was 93.3%,which was significantly higher than that of the control group,which is 70%(P<0.05).Before treatment,there were no significant differences in joint functional activity,pain visual analogue scale(VAS),health assessment questionnaire(HAQ-DI)and laboratory indexes between the two groups(P>0.05).After treatment,each group compared to their initial condition,respectively,showed major improvement of joint functional activity and significantly decreased VAS,HAQ-DI,and RA-related biomarkers(P<0.05);inter-group comparison of these indicators showed significanty further enhanced effect of TCM fumigation combined therapy on the RA-related biomarkers and joint functional activity of patients(P<0.05),yet the control group receiving only modern medicine showed better results of the VAS and HAQ-DI.Conclusion:The TCM fumigation combined therapy is effective to treat RA patients with cold-dampness Bi syn-drome,and to enhance their life quality,improving the joint function,and reducing inflammation.

Effects of 60-day NO_2 fumigation on growth,oxidative stress and antioxidative response in Cinnamomum camphora seedlings

Objective： To study the oxidative stress and antioxidative response of Cinnamomum camphora seedlings exposed to nitrogen dioxide （NO2） fumigation. Methods： Measurements were made up of the growth, chlorophyll content, chlorophyll fluorescence, antioxidant system and lipid peroxidation of one-year-old C. camphora seedlings exposed to NO2 （0.1, 0.5, and 4 μl/L） fumigation in open top chambers over a period of 60 d. Results： After the first 30 d, 0.5 and 4.0 μl/L NO2 showed insignificant effects on the growth of C. camphora seedlings. However, exposure to 0.5 and 4.0 pilL NO2 for 15 d significantly reduced their chlorophyll content （P〈0.05）, enhanced their malondialdehyde （MDA） content and superoxide dismutase （SOD） activity （P〈0.05）, and also significantly reduced the maximal quantum yield of PSII in the dark [the ratio of variable fluorescence to maximal fluorescence （Fv/Fm）] （P〈0.05）. In the latter 30 d, 0.5μl/L NO2 showed a positive effect on the vitality of the seedlings, which was reflected by a recovery in the ratio of Fv/Fm and chlorophyll content, and obviously enhanced growth, SOD activity, ascorbate （AsA） content and glutathione reductase （GR） activity （P〈0.05）; 4.0 pilL NO2 then showed a negative effect, indicated by significant reductions in chlorophyll content and the ratio of Fv/Fm, and inhibited growth （P〈0.05）. Conclusion： The results suggest adaptation of C. camphora seedlings to 60-d exposure to 0.1 and 0.5 μl/L NO2, but not to 60-d exposure to 4.0 pilL NO2 C. camphora seedlings may protect themselves from injury by strengthening their antioxidant system in response to NO2-induced oxidative stress.

Effect of Chinese Herbal Fumigation Combined with Tuina on Vertigo and Concentrations of Endothelin and Calcitonin Gene-related Peptide in Patients with Vertebral Artery Cervical Spondylosis

Objective： To observe the effect of Chinese herbal fumisation combined with three-step tuina manipulation on concentration of endothelin （ET） and calcitonin gene-related peptide （CGRP） and vertigo in patients with vertebral artery cervical spondylosis （VACS）. Methods： A total of 120 eligible cases were randomly allocated into an observation group and a control group, 60 in each group. Cases in the observation group were treated with Chinese herbal fumigation combined with three-step tuina manipulation, whereas cases in the control group were treated with oral Flunarizine Hydrochloride Capsules. Results： After treatment, vertigo in both groups was alleviated; there were intra-group significant differences in ET decrease and CGRP increase （P〈0.01, P〈0.05）; and there were also inter-group significant differences （both P〈0.05）. Conclusion： Chinese herbal fumigation combined with three-step tuina manipulation can regulate the levels of ET and CGRP and improve vertigo in patients with VACS. Its therapeutic efficacy is superior to oral Flunarizine Hydrochloride Capsules.

Disinfection efficiency of positive pressure respiratory protective hood using fumigation sterilization cabinet

Concerns have been raised about both the disinfection and the reusability of respiratory protective equipment following a disinfection process.Currently,there is little data available on the effects of disinfection and decontamination on positive pressure respiratory protective hoods(PPRPH).In this study,we evaluated the effect of vaporized hydrogen peroxide(VHP)on the disinfection of PPRPH to determine applicability of this method for disinfection of protective equipment,especially protective equipment with an electric supply system.A hydrogen peroxide-based fumigation sterilization cabinet was developed particularly for disinfection of protective equipment,and the disinfection experiments were conducted using four PPRPHs hung in the fumigation chamber.The pathogenic microorganism Geobacillus stearothermophilus ATCC 7953 was used as a biological indicator in this study and the relationship between air flow(the amount of VHP)and disinfection was investigated.Both function and the material physical properties of the PPRPH were assessed following the disinfection procedure.No surviving Geobacillus stearothermophilus ATCC 7953,both inside and outside of these disinfected PPRPHs,could be observed after a 60 min treatment with an air flow of 10.5–12.3 m^(3)/h.Both function and material physical properties of these PPRPHs met the working requirements after disinfection.This study indicates that air flow in the fumigation chamber directly influences the concentration of VHP.The protective equipment fumigation sterilization cabinet developed in this paper achieves the complete sterilization of the PPRPHs when the air flow is at 10.5–12.3 m^(3)/h,and provides a potential solution for the disinfection of various kind of protective equipment.

Objective： To observe the clinical efficacy of combining tuina and Chinese herbal fumigation for chronic ankle sprain. Methods： A total of 93 cases were randomly allocated into an observation group（n=47） and a control group（n=46） according to the table of random number. Cases in the observation group received tuina combining with Chinese herbal fumigation, whereas cases in the control group received oral blood-circulating and pain-alleviating capsules combining with Chinese herbal fumigation. Both tuina and Chinese herbal fumigation were done once every other day and 10 times made up a course of treatment. The Baird-Jackson ankle scoring system and clinical efficacy were observed after 1 course of treatment.Results： After treatment, except for radiographic findings, there were significant intra-group differences in individual item scores of Baird-Jackson（P〈0.05, P〈0.01）; except for ankle joint range of motion（ROM）, there were significant betweengroup differences in individual item scores and total score（P〈0.01）. The excellence and good rate was 76.6% in the observation group, versus 54.4% in the control group, showing a statistical significance（P〈0.05）. Conclusion： Combining Chinese herbal fumigation and tuina based on the muscle region theory can obtain better effect than combining oral blood-circulating and pain-alleviating capsules and Chinese herbal fumigation for chronic ankle sprain.
