Objective To investigate the effects of terahertz(THz)radiation on mouse testicular tissue and its potential molecular mechanisms.Methods A total of 125 male C57BL/6J mice(6~8 weeks old)were randomly divided into control group and low-,medium-and high-radiation power groups.The mice of the latter 3 groups were exposed to THz radiation at a frequency of 2.5 T,with an average power density of 38,115,or 318 mW/cm2,for 5 or 10 min.The detection time was immediately or 24 h after exposure.HE staining was used to observe pathological damage.ELISA was employed to detect the expression of inflammatory factors in testicular tissue.RNA-seq was utilized to detect the global changes of gene expression.The differentially expressed genes(DEGs)were screened and bioinformatics was used to cluster them.The screened genes were further analyzed with RT-qPCR to determine the time-dependent and dose-dependent relationships of the expression with THz exposure.Finally,sperm quality was evaluated morphologically using a microscope.Results Three doses of THz radiation exposure did not cause significant pathological damages to mouse testicular tissue.TNF-α expression was increased immediately after exposure at average power density of 115 mW/cm2(P<0.01),and the expression of IL-1β and TNF-α were both increased when the dose reached 318 mW/cm2(P<0.01).However,all the 3 factors returned to normal levels in 24 h after exposure.RNA-seq results showed that THz radiation exposure caused abnormal expression of 56 genes.Cluster analysis indicated that these DEGs were mainly enriched in immune and inflammatory responses,enzyme activity,sperm development and capacitation functions.Then for 5 selected key genes,Crisp1,Adam7,Ltf,Rnase9,and Bsph1,the expression of Crisp1 and Rnase9 was decreased immediately after exposure to 115 mW/cm2 THz radiation,the dose of 318 mW/cm2 resulted in obvious changes in the expression of the 5 genes(P<0.05),and their expression returned to normal levels in 24 h after exposure.Morphological observation displayed that exposure to all the 3 doses of THz had no influence on sperm quality.Conclusion THz radiation exposure causes temporary inflammatory response in testicular tissue and abnormal expression of sperm functions-related genes.However,these changes return to normal 24 h after exposure,and additionally,do not impair sperm quality.

ObjectiveTo investigate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) during pregnancy and puerperium through a comparative analysis. MethodsA retrospective analysis was performed for the clinical data of 22 patients in pregnancy and 39 patients in puerperium who received ERCP in Digestive Endoscopy Center of The First Affiliated Hospital of Nanchang University from January 2007 to August 2022. The two groups of patients were compared in terms of baseline data, diagnosis during ERCP, interventions, laboratory results before and after ERCP, post-ERCP complications, and delivery and fetal outcomes. The independent-samples t test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsThere were no significant differences between the patients in pregnancy and those in puerperium in all baseline data (all P>0.05) except the rate of CT examination (22.73% vs 58.97%, χ2=7.44, P=0.006). During the ERCP procedure, compared with the patients in puerperium, the patients in pregnancy had a significantly lower proportion of the patients who underwent biliary stone extraction or endoscopic papillary balloon dilation (χ2=4.007 and 4.315, both P<0.05) and a significantly higher proportion of the patients who did not receive X-ray fluoroscopy (χ2=12.103, P=0.001). After ERCP, both groups had significant improvements in white blood cell count, total bilirubin, direct bilirubin, alanine aminotransferase, and aspartate aminotransferase (all P<0.05). The overall incidence rate of post-ERCP complications was 7.04% (5/71) for all patients, with post-ERCP biliary infection as the most common complication (3/71,4.23%), and there was no significant difference in the incidence rate of post-ERCP complications between the two groups (P>0.05). As for delivery and fetal outcomes, compared with the patients in puerperium, the patients in pregnancy had a significantly higher proportion of patients with early termination of pregnancy (50.00% vs 0,χ2=20.528, P<0.001) and a significantly lower proportion of patients with cesarean section (36.36% vs 76.92%, χ2=4.756, P=0.029). There were no significant differences in the incidence rates of adverse events such as abnormal fetal development and stillbirth between the two groups (P>0.05). ConclusionWith strict control of ERCP indications and timing, ERCP is effective and relatively safe in both pregnancy and puerperium and has a comparable incidence rate of post-ERCP complications to that in the general population, with relatively good delivery and fetal outcomes.

Astract:Objective To investigate the ultrastructural changes and HSP70 expression in liver of mice after microwave irradiation with lethal dose and to explore the application of these indexes as the basis of medical identification in microwave irradiation induced death. Methods The mice were divided into the control group and the irradiation group. Mice of the irradiation group were induced death by whole body exposure to 129 W/cm2 microwave irradiation for 30 minutes. The ultrastructure of liver was observed by transmission electron micro-scope;changes of the HSP70 mRNA and protein expression in liver were detected by reverse transcription polymerase chain reaction ( RT-PCR) and Western blotting respectively. Results Liver cytoplasm was observed dissolved with points and sheets and there were mitochondri-al crest and membrane solution in the irradiation group. And the HSP70 mRNA and protein expression level increases significantly compared with the control group with statistically significant difference (P<0. 01). Conclusion Death induced by microwave irradiation could lead to liver cytoplasm dissolution, mitochondria damage, mRNA and protein expression of HSP70 up-regulation, which may be used as important diagnostic indicators of microwave irradiation induced death.

AIM:Early calcification of atherosclerotic plaques are colocalized with macrophage and high mobility group box 1 (HMGB1), a cytokine associated with biomineralizing process under physiological and pathological conditions .Our study aims to evaluate whether HMGB1 induces ectopic mineralization via promoting the secretion of matrix vesicles ( MVs) from macrophages .METHODS:HMGB1 was added to the medium of macrophages , the secretion of MVs in the supernatant was tested by flow cytometry analysis .The mineral deposition in calcifying medium was detected by Alizarin Red staining and von Kossa staining .Transmission electron microscopy showed the formation of hydroxyapatite crystals in MVs .Then we subcutaneous injection into mice with MVs to induce regional minera-lization.RESULTS:HMGB1 significantly promoted secretion of MVs from macrophages as raveled by flow cytometry analysis .TNAP activity, considered as a marker of MVs maturation , was higher in HMGB1-induced MVs compared to the control-MVs.HMGB1-MVs also led to mineral deposition in an in vitro MVs-collagen mineralization model .Subcutaneous injection into mice with MVs derived from HMGB1-treated cells showed a greater potential to initiate regional mineralization .Mechanistic experiments revealed that HMGB 1 activated neutral sphingomyelinase 2 ( nSMase2 ) that involved the receptor for advanced glycation end products ( RAGE ) and p38 MAPK (upstream of nSMase2).Inhibition of nSMase2 with GW4869 or p38 MAPK with SB-239063 prevented MVs secretion and min-eral deposition .CONCLUSIONS: HMGB1 induces MVs secretion from macrophages at least in part , via the RAGE/p38 MAPK/nSMase2 signaling pathway .Our findings thus reveal a novel mechanism by which HMGB 1 may participated in the early calcification of atherosclerotic plaques .
