Objective To investigate the safety and efficacy of ultrasound ablation in treatment of uterine fibroids. Methods Ninety-nine patients with 117 leiomyomas in total treated by Haifu JC focused ultrasound tumor therapeutic system were enrolled in prospective and non-randomized clinical trial in First Affiliated Hospital of Chongqing Medical University and Academy of Military Medical Sciences. Ultrasound ablation was performed guided by real-time ultrasonography under conscious sedation for single session. All patients were followed up at 6 months after treatment. On the day of treatment and after 1 month, patients were given by magnetic resonance imaging(MRI) exam to evaluate the effect of fibroids ablation. At 3 and 6months after treatment, the ratio of ablated area and volume reduction of fibroids more than 50% were evaluated by MRI exam again. The symptoms improvements were evaluated by uterine fibroid symptom (UFS) and complications were analyzed by guideline of society of international radiation (SIR). Results The average ablated area ratio of the target fibroid was (76 ± 24)%. The average reduction in fibroid volume determined by MRI at 3 and 6 months after treatment was (45 ± 21)% and (59 ± 26)%. Which were significantly decreased than those before treatment (P < 0. 05). At 6 months after treatment, 84. 6% (99/117) of patients showed more than 50% volume reduction, the rate of improved symptom score was 92%(66/72). All patients could resume normal daily activities at 2 hours after treatment. The adverse reactions of SIR C - D included delayed hospitalization, repeat treatment and increased level of nursing. E - F included permanent sequelae and death. In this study, no adverse reactions of C - F were recorded. Common complications (SIR A- B, only observation or simple management without sequelae) were 35% (35/99).Four cases with adverse reactions B of SIR were found, including 2 cases with skin burning of degree Ⅱ and 2 cases with febrile, they were administered by symptomatic therapy and changing dressing The other adverse reaction A of SIR included sorness of buttock, vaginal discharge, dysuria and painful urination, they were only suggested by follow-up. Conclusion It was efficacy and safe that ultrasound ablation as a single strategy were used in treatment of uterine fibroids.

Objective:To study the complications and prognosis of extremely premature infants(EPIs) with gestational age (GA) <28 w.Methods:From January 2016 to December 2020, EPIs with GA <28 w admitted to NICU of our hospital were retrospectively studied. Clinical data of the infants and their mothers during pregnancy were reviewed. According to the prognosis, the infants were assigned into the survival group, the death group and the withdrawal group. According to GA, the infants were assigned into <26 w goup, 26~26 +6 w group, ≥27 w group. According to birth weight (BW), the infants were assigned in to ≤750 g group, 750~999 g group and ≥1 000 g group. SPSS 26.0 was used for data analysis. Results:A total of 265 EPIs were included, 122 (46.0%) in the survival group, 47 (17.7%) in the death group and 96 (36.2%) in the withdrawal group. GA and BW of the survival group were significantly higher than the death group and the withdrawal group ( P<0.05). The incidences of tracheal intubation (92.2%) and pulmonary hemorrhage (42.2%) in the death group were the highest among the three groups. The survival group had the highest application of prenatal glucocorticoids (80.3%) and pulmonary surfactants (99.2%) ( P<0.05). In the survival group, the top 3 common complications were bronchopulmonary dysplasia (BPD) (68.0%), pulmonary infections (65.6%) and neonatal sepsis (34.4%). The survival rate increased with GA and BW. Conclusions:The survival rate of EPIs is closely correlated with GA and BW. EPIs with pulmonary hemorrhage and tracheal intubation have poor prognosis. Prenatal glucocorticoids and pulmonary surfactant may improve clinical outcome. BPD and pulmonary infections are common complications of surviving EPIs.

BACKGROUND:Photothermal therapy is a novel tumor treatment strategy that uses photothermal agents to transform light energy into heat energy to accomplish non-invasive tumor ablation.The rise of photothermal therapy and nanotechnology has provided a new perspective on breast cancer treatment.OBJECTIVE:To prepare a new type of near-infrared biomimetic nanoprobe that has been modified by breast cancer cell membrane,to investigate the effect of near-infrared fluorescence/ultrasound imaging in vitro,and to observe its targeting ability and photothermal therapy effect on homologous tumor cells in vitro.METHODS:Organic small molecule ITIC-4CI with A-D-A structure was used as photothermal agents;polylactic acid/glycolic acid copolymer as nanocarrier;4T1 cell membrane of mouse breast cancer cells as a surface modifier of nanoparticles;perfluorohexane(PFH)was loaded.A novel near-infrared biomimetic nanoprobe(4T1m/ITIC-4CI/PFH)was prepared by the double emulsion evaporation method and sonication method.The basic characterization of the nanoprobe and the homologous targeting ability were detected.The photothermal properties and photothermal stability of the probe were investigated,and the near-infrared fluorescence/ultrasound imaging effect of the probe under laser irradiation was observed.The CCK-8 assay and calcein/propidium iodide staining were used to assess the efficacy of photothermal therapy.RESULTS AND CONCLUSION:(1)The prepared 4T1m/ITIC-4CI/PFH nanoprobes had uniform size,high stability,and an average particle size of(92.7±2.3)nm.The probe's protein composition was identical to that of the 4T1 cell membrane.The nanoprobe's ability to target homologous 4T1 cells was validated by an in vitro cell uptake assay.(2)The nanoprobe had a red-shift absorption spectrum and tail emission extending to the near-infrared-Ⅱ,which emitted a bright near-infrared-Ⅱ fluorescence signal under laser irradiation.(3)After laser irradiation,the nanoprobe 4T1m/ITIC-4CI/PFH could be turned into microbubbles and enhanced ultrasound imaging.The results of CCK-8 assay and calcein/propidium iodide staining showed that the nanoprobe 4T1m/ITIC-4CI/PFH had an obvious photothermal killing effect on 4T1 cells.(4)The results show that the nanoprobe 4T1m/ITIC-4CI/PFH has the ability to target homologous tumors and enhance near-infrared-Ⅱ fluorescence imaging/ultrasound imaging and photothermal therapy effects.

Objective:To explore the prevalence and risk factors of thyroid diseases in the physical examination population of Hohhot.Methods:From July 2017 to July 2018, 3 100 health examinees from Inner Mongolia National Examination Medical Center were selected as subjects for questionnaire survey, thyroid function test and thyroid ultrasound examination; a multinomial logistic regression model was used to analyze the relationship between relevant investigation factors and different types of thyroid diseases (simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules).Results:Among the 3 100 healthy examinees, there were 2 885 effective responders, including 743 males and 2 142 females, aged (46.23 ± 12.32) years; the simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules were 909, 648, and 619 cases, respectively, and the detection rates were 31.51%, 22.46%, and 21.46%, respectively. Logistic regression analysis results showed that age [35 - 54 years old: odds ratio ( OR) = 1.30, 95% confidence interval ( CI): 1.01 - 1.68; ≥55 years old: OR = 2.30, 95% CI: 1.68 - 3.14, P < 0.05], gender ( OR = 1.65, 95% CI: 1.32 - 2.07, P < 0.05), obesity ( OR = 1.35, 95% CI: 1.08 - 1.70, P < 0.05), and mental stress [significant: OR = 1.64, 95% CI: 1.09 - 2.48; some: OR = 1.54, 95% CI: 1.02 - 2.32, P < 0.05] were the risk factors affecting the occurrence of simple thyroid nodules. The age (35 ~ 54, ≥55 years old), gender, bad mood (a little), and mental stress (significant) were risk factors that affected the occurrence of simple thyroid dysfunction; eating high iodine food was its protective factor. The age (35 ~ 54, ≥55 years old), gender, obesity, and thyroid family genetic history were risk factors for thyroid dysfunction with nodules; the consumption of iodized salt was its protective factor. Conclusions:Older women are high-risk groups for thyroid diseases. Obesity, bad mood, mental stress will increase the risk of the disease. Daily consumption of iodized salt and moderate consumption of high iodine food can reduce the risk of the disease.

AIM: To investigate the correlation between fundus blood flow parameters and carotid artery ultrasound blood flow parameters in patients with hypertensive retinopathy(HRP).METHODS: A total of 50 patients(22 left eyes and 28 right eyes)with HRP admitted to our hospital from June 2021 to June 2023 were retrospectively included as the experimental group, and 50 healthy physical examination subjects(22 left eyes and 28 right eyes)during the same period were included as the healthy group. Pearson correlation was used to analyze the correlation between fundus blood flow parameters and carotid artery ultrasound blood flow parameters.RESULTS: The AUC values of fundus blood flow parameters and carotid artery ultrasound blood flow parameters and their combined diagnosis of HRP were 0.853, 0.844 and 0.935, respectively. Pearson correlation analysis showed that carotid systolic peak blood flow velocity was negatively correlated with foveal avascular zone(FAZ)area, FAZ circumference and non-circularity index, and positively correlated with macular vascular density(all P<0.05). The end-diastolic blood flow velocity was positively correlated with FAZ area and macular vascular density(all P<0.05). The internal carotid artery resistance index was positively correlated with FAZ area(P<0.05).CONCLUSION: The combination of fundus blood flow parameters and carotid artery ultrasound blood flow parameters in the diagnosis of HRP has good application value in the diagnosis of HRP.
