Objective:To preliminarily evaluate the lumen gain of sonodynamic therapy (SDT) mediated by sinoporphyrin sodium at carotid and femoral atherosclerotic plaque sites, and to assess whether concomitant statin use, lesion location, plaque echogenicity/type, and baseline stenosis severity modify the therapeutic response.Methods:This single-center, prospective, exploratory pilot clinical study enrolled patients with peripheral artery disease who attended the outpatient cardiology clinic of the First Affiliated Hospital of Harbin Medical University between February and September 2016. All enrolled patients received optimized oral medical therapy in combination with a single session of SDT. Vascular evaluation was performed using color Doppler ultrasound before treatment and 1 and 4 weeks after treatment. The primary efficacy endpoint was the percent change from baseline in luminal diameter stenosis at the site of the atherosclerotic plaque (%Δ) at week 4, while the secondary efficacy endpoint was %Δ at week 1. Subgroup analyses were conducted according to prior statin use, plaque location, plaque characteristics, and baseline degree of luminal stenosis.Results:A total of 24 patients, aged (70.7±2.2) years were enrolled. There were 20 (83%) males. Compared to baseline, luminal diameter stenosis at the plaque site reduced by week 4 ((50.1±1.2)% vs. (57.2±1.1)%, P<0.001), %Δ was(12.32±1.05)%; and luminal diameter stenosis also reduced by week 1 ((51.7±1.2)% vs. (57.2±1.1)%, P<0.001)), %Δ was(9.61±0.85)%. In subgroup analyses, the treatment effect on diameter stenosis was independent of prior statin use; SDT reduced stenosis in both carotid and femoral plaques; with superior efficacy observed in hypoechoic and mixed-echo plaques; and efficacy was observed across mild, moderate, and severe baseline stenosis categories (all P<0.05). Conclusion:In this single-center pilot study, SDT demonstrates therapeutic efficacy across mild, moderate, and severe stenoses, as well as in hypoechoic and mixed-echo plaques, showing potential to rapidly promote luminal gain at carotid and femoral atherosclerotic plaque sites.

The course, progression, and prognosis of fetal congenital cystic adenomatoid malformation (CCAM) depend on the size of the mass, whether the mediastinum is displaced, changes in fetal hemodynamics, and the occurrence of fetal hydrops, with large CCAM being relatively rare. In this case, a fetus was suspected of having a large CCAM with fetal hydrops and cardiac insufficiency at 27 weeks of gestation. After multiple imaging evaluations and multidisciplinary consultations, a delivery plan and neonatal resuscitation plan were formulated. At 31 +4 weeks of gestation, in-utero thoracentesis and drainage were performed. Postoperatively, the fetal CCAM was reduced compared to before, and the maternal symptoms of chest tightness and shortness of breath were also improved. Three days after the procedure, the mother experienced premature rupture of membranes and delivered a male infant vaginally at 32 weeks of gestation. On the fifth day after birth, the newborn underwent resection of the pulmonary cystic adenomatoid malformation, confirming the diagnosis. Follow-up for two years post-birth showed good prognosis for both the mother and the child. Therefore, when CCAM is detected during pregnancy, thorough in-utero evaluation should be conducted, and a monitoring plan should be developed based on potential perinatal conditions to avoid unnecessary termination of pregnancy. If the pregnancy continues, multidisciplinary evaluation and preparation for perinatal surgery are necessary.

Antenatal corticosteroids (ACS) have been used clinically for more than half a century. They effectively reduce the incidence of preterm-related complications, such as neonatal respiratory distress syndrome (NRDS). Based on the significant beneficial effect in singleton pregnancies, several international guidelines recommend that ACS for twin pregnancies refer to their singleton pregnancies protocol. However, the prevention effect of ACS on NRDS in twin pregnancy is inconsistent. This review summarizes the effects of ACS on the prevention of NRDS in twin pregnancy to provide a reference for clinical management and further study.

We report a woman with twin pregnancy who suffered from repeated late postpartum hemorrhage at 16 days and 22 days after a cesarean section. Tortuous myometrial vessels with significant flow signal on the uterus were discovered through color Doppler ultrasonography. In both occasions, vaginal bleeding was reduced after uterotonic administration, and Doppler ultrasound found gradually narrowed tortuous tubular myometrial vessels and no further massive vaginal bleeding. Regular Doppler ultrasonography follow-up is of vital importance for the diagnosis and monitoring of recurrent late postpartum hemorrhage.

Thyroid-associated ophthalmopathy (TAO) is a kind of autoimmune disease which has complex clinical manifestations.The treatment is diverse and controversial but the effect is uncertain.Nonsurgical treatment is particularly critical in the process of diseases.However, there is no uniform standard for clinical use among various methods,which often makes it difficult to develop the treatment program.This paper summarizes and compares the methods that have been proven or are expected to be effective in the treatment of TAO in recent years, which committed to provide a reference for clinicians.

In this paper , 2280 strains of suspicious Shigella c culture were detected by the diagnostic typing phage set for Enterobacteriaceae, the routine identification of them were carried oat at the same time . The results showed that 100% of shigella cultures were lysed with 10~3RTD and 99.9% lysed with 1RTD of phage Sh. 12.3% of 65 non-shigeUa cultures agglutinating with typing serum of shigeUa was lysed with 10~3RTD, 4.6% lysed with 1RTD of phage Sh. The determination of lytic-pattern of 2215 shigella culture indicated that only 3 strains of Boyd 5 of lytic-pattern 3 were not reported in literature, the rest strains were consistent to fomer studies. The nonshigella cultures lysed by Sh 10~3RTD could be excluded with 1RTD and its lytic-pattern. 20 strains of Enteroinvasive Escherichia coli possessing shigeUa-related antigens could be differentiated by Sh 10~3RTD. 1RTD and its lytic-pattern.
