Objective To investigate the role of hydrogen therapy in reducing radiation-induced lung injury and the specific mechanism. Methods Forty C57BL/6 mice were randomly divided into four groups: normal control group, model group, hydrogen therapy group I, and hydrogen therapy group II. A mouse model of radiation-induced lung injury was established. The pathological changes in the lung tissue of the mice were examined with HE staining. Immunofluorescence staining was used to detect the expression of surface markers of M1 and M2 macrophages to observe macrophage polarization. The expression of interleukin (IL)-6, tumor necrosis factor-α (TNF-α), and IL-10 in the lung tissue was measured by immunohistochemistry. The expression of nuclear factor-kappa B (NF-κB) p65 and phosphorylated NF-κB (P-NF-κB) p65 was measured by Western blot. Results HE staining showed that compared with the control group, the model group exhibited alveolar septal swelling and thickening, vascular dilatation and congestion, and inflammatory cell infiltration in the lung tissue; the hydrogen groups had significantly reduced pathological damage and inflammatory response than the model group, with more improvements in hydrogen group II than in hydrogen group I. Immunohistochemical results showed that compared with those in the control group, the levels of the inflammatory cytokines IL-6 and TNF-α were significantly increased in the model group; the hydrogen groups showed significantly decreased IL-6 and TNF-α levels and a significantly increased level of the anti-inflammatory factor IL-10 than the model group, which were more marked in hydrogen group II than in hydrogen group I. Immunofluorescence results showed that compared with the control group, the expression of the surface marker of M1 macrophages in the model group was significantly upregulated; the hydrogen groups showed significantly downregulated M1 marker and significantly upregulated M2 marker, and hydrogen group II showed significantly increased M2 marker compared with hydrogen group I. Western blot results showed that compared with that in the control group, the ratio of P-NF-κB p65/NF-κB p65 in the model group was significantly increased; the P-NF-κB p65/NF-κB p65 ratio was significantly reduced in the hydrogen groups than in the model group, and was significantly lower in hydrogen group II than in hydrogen group I. Conclusion Hydrogen inhalation therapy may reduce the inflammatory response of radiation-induced lung injury by inhibiting the NF-κB signaling pathway to promote the polarization of the macrophage M1 subtype to the M2 subtype.

Objective:To analyze the prognosis of glucose metabolism and its impacting factors at 6-12 weeks postpartum in patients with abnormal blood glucose during pregnancy.Methods:In this cross-sectional study, a total of 192 patients with abnormal blood glucose during pregnancy enrolled and delivered in the maternity clinic of Daxing Teaching Hospital of Capital Medical University from December 1, 2019 to December 31, 2020 were collected. The 75 g oral glucose tolerance test (OGTT) was applied for diabetes screening at 6-12 weeks after delivery. According to the results of postpartum blood glucose, the patients were divided into two groups: postpartum normal blood glucose group (148 cases) and abnormal blood glucose group (44 cases). Hypothesis testing was used to compare the clinical data before, during and after the pregnancy between the two groups. Multi-factor logistic regression was performed to analyze the influencing factors of postpartum abnormal blood glucose in patients with abnormal blood glucose during pregnancy.Results:Among the 192 patients with abnormal blood glucose during pregnancy, the incidence of postpartum abnormal blood glucose was 22.92% (44/192), including 6 cases of diabetes mellitus (DM) (13.64%), 38 cases of impaired glucose tolerance (IGT) (86.36%). Neck circumference, waist circumference, multiparous women and insulin use during pregnancy in postpartum abnormal blood glucose group were all significantly higher than those in postpartum normal blood glucose group [34.25(33.00, 36.00) vs 33.55 (32.00, 35.00) cm, 87.00 (82.00, 93.00) vs 84.00 (78.00, 90.00) cm, 54.55% vs 37.16%, 18.18% vs 6.76%] (all P<0.05). Neck circumference ( OR=1.315, 95% CI: 1.026-1.685), multiparous women ( OR=2.261, 95% CI: 1.057-4.836), insulin use during pregnancy ( OR=3.767, 95% CI: 1.236-11.478) were positively correlated with the occurrence of postpartum abnormal blood glucose (all P<0.05). Conclusions:The incidence of postpartum abnormal blood glucose is high at 6-12 weeks postpartum in patients with abnormal blood glucose during pregnancy. Neck circumference, waist circumference, parity and insulin use during pregnancy are important impacting factors of postpartum abnormal blood glucose.

Objective:To investigate the effects of sodium-glucose cotransporter 2 inhibitor dapagliflozin on myocardial remodeling in mice with diabetic cardiomyopathy and related mechanisms.Methods:Between January and December 2021, 60 6-week-old male C57BL/6J mice were chosen for the study, 40 were used to establish a diabetic cardiomyopathy model and the model was established in 28 mice, of whom, 14 were assigned to a non-intervention group and 14 to a dapagliflozin treatment group(intervention group).The rest of the 20 mice were in the control group.The mice in the intervention group were treated with dapagliflozin via oral gavage for 12 weeks.Cardiac structure and function were measured by ultrasound, the degree of myocardial fibrosis was evaluated by histology and electron microscopy, the concentrations of inflammatory factors were detected by enzyme-linked immunosorbent assays, apoptosis of myocardial cells was examined by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling(TUNEL), and the level of myocardial oxidative stress was evaluated by dihydroethidium fluorescence.Results:At the end of the experiments, the body weight and fasting blood glucose in the intervention group were slightly lower than in the non-intervention group, but the difference was not statistically significant, while values from cardiac function parameters such as left ventricular ejection fraction were more favorable than in the non-intervention group[(61.07±4.66)% vs.(45.8±4.80)%, t=-5.24, P<0.05].Compared with the non-intervention group, the intervention group had alleviated myocardial hypertrophy, less myocardial disarray, and reduced collagen volume fraction[(18.4±1.9)% vs.(31.8±3.7)%, t=-12.0, P<0.05].Furthermore, the concentrations of inflammatory factors in the intervention group were lower than in the control group[interleukin-6: (82.19±10.90)ng/L vs.(291.02±31.02)ng/L, t=23.8, P<0.05; tumor necrosis factor-α: (70.45±12.13)ng/L vs.(201.31±27.10)ng/L( t=16.5), P<0.05; perforin 3: (13.05±2.04)μg/L vs.(42.40±1.26)μg/L( t=45.8), P<0.05; the index of myocardial apoptosis: 1.736±0.247 vs.0.864±0.129, t=11.7, P<0.05].The level of myocardial oxidative stress in the non-intervention group was higher than in the intervention group(2.655±0.252 vs.1.274±0.298, t=-13.3, P<0.05). Conclusions:Dapagliflozin can reduce myocardial hypertrophy and inhibit myocardial fibrosis through mitigating myocardial oxidative stress and inflammatory response, thus suppressing myocardial remodeling and ultimately protecting cardiac function in diabetic cardiomyopathy mice.

Objective:To explore the effective method for treatment of small and short penis after hypospadias surgery.Method:s From November 2017 to November 2018, 57 children aged 4 to 14[mean age(7.91±2.89)years] with hypospadias who met the diagnostic criteria of small penis were reexamined at the First Affiliated Hospital of Xin-xiang Medical University.They were randomly divided into the physical treatment group and the drug treatment group according to the order of visits, and the untreated patients were included in the control group.Among them, 21 patients in the physical treatment group were treated with penile rehabilitation therapy apparatus, supplemented by Salvia mil-tiorrhiza bath (30 minutes/time, once/day, 10 days), and 20 patients in the drug treatment group were treated with Testosterone cream topically (3 times/day, 10 days). Penile relaxation length, stretch length, transverse and longitudinal diameters of glans in 2 groups before and after the treatment were measured.The relevant indexes of 16 patients in the control group measured before and after 10 days and compared with those in the treatment group.Result:s (1)The penile relaxation length in the physical treatment group increased from (25.48±6.13) mm to (30.72±6.49) mm, the length of stretch increased from (34.90±7.71) mm to (41.08±8.43) mm, the transverse diameter of glans increased from (14.81±3.40) mm to (16.57±3.42) mm, and the longitudinal diameter increased from (13.94±3.15) mm to (15.82±3.52) mm, and the differences were statistically significant (all P<0.05). (2)The penile relaxation length in the drug treatment group increased from (21.07±4.26) mm to (31.32±4.72) mm, the length of stretch increased from (31.94±7.96) mm to (45.39±7.24) mm, the transverse diameter of glans increased from (13.38±1.77) mm to (16.64±2.10) mm, and the longitudinal diameter increased from (13.09±1.77) mm to (16.62±1.86) mm, and the differences were statistically significant (all P<0.05). (3)There was no significant difference in penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans before and after 10 days in the control group (all P>0.05). (4) Compared with the control group, the penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans in the physical treatment group increased significantly, and the differences of growth values between the two groups were statistically significant (all P<0.05). (5) Compared with the control group, the penile relaxation length, the length of stretch, transverse diameter and longitudinal diameters of glans in the drug treatment group also increased significantly, and the difference of growth values between the two groups were statistically significant (all P<0.05). (6) The growth of penile relaxation length, the length of stretch and transverse and longitudinal diameters in the drug treatment group were higher than those in the physical treatment group, and the difference of growth values were statistically significant (all P<0.05). Conclusions:Both the negative pressure suction method and topical application of Testosterone cream are effective in the treatment of small and short penis after hypospadias surgery.However, Testosterone cream is difficult to obtain, and the treatment of negative pressure suction is simple, noninvasive, painless and free of adverse reactions.

Hypothyroidism is a common adverse reaction in clinical multi-target tyrosine kinase inhibitor (TKI) and may be used as a predictor of efficacy of TKI drugs.Studies show that hypothyroidism is significantly associated with good prognosis in patients with renal cell carcinoma treated with multi-target TKI,which may be related to inhibition of vascular endothelial growth factor receptor pathway,potential off-target effects and inhibition of cell proliferation.Whereas in the patients with hepatocellular carcinoma who received multi-target TKI therapy,hypothyroidism is an indicator of poor prognosis,which is related to the T3/TR pathway regulating liver cancer growth and invasion.The predictive function and mechanism of thyroid hormone levels in different tumor patients receiving multi-target TKI drugs are different,and further research is still needed.
