In order to investigate the hygienic characteristic of anti-immersion trousers, ten male soldiers dressed in the trousers or in camouflage trousers were subjected to exercise test and sedentary test respectively at room temperature of 17?2℃. In the test, eleven parameters such as core temperature, skin temperature, heat flow and so on were observed. The results indicated that in sedentary tests, the low limb heat flow of the subjects dressed in anti-immersion trousers was larger than that dressed in camouflage trousers; the heat insulation value of anti-immersion trousers was smaller than that of camouflage trousers; and for the other parameters, there was no evident difference between the two group. It suggested that when used on land, hygiene characteristic and effect on body heat balance of the anti-immersion trousers were similar to those of camouflage trousers.

OBJECTIVE To explore the effects of perinatal inflammation on the expression of proin-flammatory cytokines and DMEs (drug metabolism enzymes) in offspring mice. METHODS C57BL/6 maternal mice were administrated with single dose 100 μg·kg-1LPS(lipopolysaccharide)or saline(vehicle) during gestation (day 10 after fertilization). Offspring mice were sacrificed at 30 d after birth and liver samples were collected.Real-time PCR was adopted to test the mRNA expression of proinflammatory cytokines (Nrlp3 and IL-1β), nuclear receptors (Pxr and Car), and DMEs (Cyp3a11, 2b10, 1a2, and Ugt1a1).RESULTS Gender different expression of candidate genes was observed.The expression of Car,in the maternal injection of LPS groups,was significantly decreased in both female and male offspring (n=3-8/group, P<0.01). Concomitantly, a significantly lower expression of Cyp3a11 was found in both female and male offspring (P<0.01, P<0.05, respectively). Furthermore, the expression of Ugt1a1 was reduced in male offspring following maternal administration of LPS (P<0.01). In male offspring, Nrlp3 expression was specially decreased(P<0.05).Interestingly,there was an approximately 66% reduction in mRNA level of Cyp1a2 in female offspring (P<0.01), while in male offspring Cyp1a2 expression showed an increased trend (P>0.05) compared with vehicle group. The expression of Pxr, Cyp2b10, and IL-1β was no difference between LPS treatment group and vehicle group(P>0.05).CONCLUSION Maternal LPS administration affects the expression of proinflammatory cytokines, nuclear receptors and DMEs in mouse offspring.

OBJECTIVE To demonstrate the long-or short-term impacts of neonatal Pxr(pregnane X receptor) agonists exposureon DMEs (drug metabolism enzymes) expression in adulthood. METHODS C57BL/6 mice(day 5,postnatal)were injected with different doses(0,50,100,150,200 mg·kg-1·d-1, constitutive 4 d)of PCN(pregnenolone-16a-carbonitrile).Mice at different ages(day 5,10,15,25,postna-tal)were administrated with 200 mg·kg-1·d-1PCN in constitutive 4 d.All mice were sacrificed at day 60 after birth. Liver samples were collected for detecting the expression of Pxr target genes. RESULTS Compared with vehicle group, the significant inductions of Cyp2b10, Cyp3a11 and Pxrwere observed in high dose groups (150, 200 mg·kg-1·d-1, 5-8 d after birth) both in male and female mice (n=4-9/group,P<0.05).Furthermore,high dose groups(200 mg·kg-1·d-1,5-8 d after birth)were found to have higher mRNA expression levels of Cyp2a4,Ugt1a1,Abcc4,and Oatpla4 in female mice,while Papss2 in male mice compared with vehicle groups (n= 4-9/group, P<0.05). Interestingly, a decreased mRNA expression of Sult2a1 was identified in 200 (5-8 d) groups (n=4-9/group, P<0.05). Consistent with these results, the protein expression of Cyp3a11 was only increased in 200 (5-8 d) groups compared with the vehicle groups(n=3/group,P<0.05).Importantly,the persistent impacts on DMEs only occurred in day 5 and day 25 treatment groups,not day 10 and day 15 groups(n=4/group).CONCLUSION Neonatal Pxr activation has a long-term effect on the expression of DMEs in C57BL/6 mice.Dose and treatment exposure time are two key factors involved in this permanent alteration procedure.

OBJECTIVETo compare the image quality of T grain green sensitive film (TML-1) and Lanex Gd(2)O(2)S rare earth intensifying screen with that of XK-1 blue sensitive film and calcium tungstate (CaWO(4)) intensifying screen, and to study the application of T grain technic to the diagnosis of lung diseases.

METHODS160 coal miners were randomly selected to take both TML-1 and XK-1 chest film of high kV radiographs at the same time. Silver halide granule, fluorescence of intensifying screen, radiographic parameters, the density at different points in the lung and chest radiographs were observed.

RESULTSSilver grains in TML-1 film were more homogeneous in distribution than in XK-1 film. Luminous intensity of Lanex Gd(2)O(2)S rare earth intensifying screen was brighter than CaWO(4) intensifying screen in the same exposure. The exposure doses of TML-1 film was reduced to one third of XK-1 film. The density of chest radiographs was 0.24 to 2.74 in TML-1 film, and 0.30 to 2.60 in XK-1 film. There were greater exposure latitude and more informations in TML-1 film. By apertured-disc observation, the fine structure of lung in TML-1 film was clearer than in XK-1 film, the shape was more concrete and reliable, visualizability was stronger.

CONCLUSIONT grain technique may obviously improve the clearness and resolution of image, and enhance the transmission of information, as well as increase the diagnostic informations.

Objective:To explore the prophylactic efficiency of dexmedetomidine on postoperative nausea and vomiting (PONV) in highly susceptible patients.Methods:By using randomized and double-blind controlled trial, 100 non-smoking female patients receiving laparoscopic surgery were selected and randomly divided into dexmedetomidine group and control group.The dexmedetomidine group received 0.6 μg/kg dexmedetomidine before induction, and 3 μg/kg dexmedetomidine after surgery.The severity of PONV, the visual analogue scale (VAS)for pain scores, the use of rescued antiemetic and analgesic drugs were assessed for 48 h postoperatively.Results:There were 93 patients completed the study (47 cases in dexmedetomidine group and 46 cases in control group).The number of patients classified as PONV 0 in dexmedetomidine group was significantly more than that in the control group during the time interval 0 to 6 h postoperatively (37 vs 27, P<0.05).The percentage of the usage of antiemetic drugs within 48 hours in dexmedetomidine group was lower than that in control group(25.5% vs 47.8%,P<0.05).During the time intervals 6 to 24 h and 24 to 48 h, the pain scores were significantly lower in dexmedetomidine group compared with control group, 2.9±0.9 vs 3.4±0.7 and 2.7±0.6 vs 3.0±0.7, respectively (P<0.05).Conclusions:Dexmedetomidine used perioperatively might decrease the severity of PONV in early phase postoperatively in highly susceptible patients, and reduce the need for antiemetic drugs and improve the analgesia effects.

Objective To carry out accurate quantative evaluation of MRI scanning noise based on laser vibrometry technology.Methods Skull and spine MRI was performed with mute and conventional sequences.A laser vibrometry device was used to sample the surface vibration noise at the outer edge of the inspection hole of MRI system according to GB/T 16539-1996 Acoustics—Determination of sound power levels of noise sources using vibration velocity—Measurement for seal machinery,and the indicators of sound power level,sound pressure level and perceived noise level obtained by the three calculation methods(LPN1,LPN2 and LPN3)were analyzed with some dedicated MRI noise analysis software.Results The peak sound pressure levels for conventional and mute sequences of skull scanning were 81 and 63 dB(A),respectively,and mute sequence reduced the noise level significantly;the peak sound pressure levels for conventional and mute sequences of spine scanning were 79 and 75 dB(A),respectively,and the noise reduction level was significantly lower than that of skull scanning.Significant differences in noise reduction were not found in spine scanning sequences,while were found in skull scanning sequences.During spine and skull scanning LPN1,LPN2 and LPN3 obtained by the three calculation methods of conventional and mute sequences were all higher than the overall sound power and overall pressure levels obviously.Conclusion Mute sequence can not realize linear noise reduction for the whole frequency band,the perceived noise of the human ear during MRI scanning is related directly to the scanning sequence,and there may be some bias when only one physical indicator is involved in the noise evaluation of MRI system.[Chinese Medical Equipment Journal,2024,45(10):20-24]
