Multimodality noninvasive cardiac imaging established the diagnosis of aneurysms of Vieussens’ arterial ring

Noninvasive cardiac imagines are rapidly evolving in recent years. In this patient with Vieussens’ arterial ring aneurysm, multimodality noninvasive cardiac imaging provided sufficient information for diagnosis and surgical decision making. This report no only provides unique information leading to better understanding on aneurysms of Vieussens’ arterial ring, but also highlights the important role of multimodality noninvasive cardiac imagines in the diagnosis and management of certain cardiac emergencies.     

Membrane technology for optimizing process optimization of small bioactive compounds in Mailuoning Injection factory effluene北大核心CSCD

Objective: To enrich small bioactive compounds from Mailuoning Injection factory effluene by polyether sulfoxide hollow fiber membrane. Methods: The retention rate of the common polymer (protein, tannin, starch, and pectin) and the permeability of the small molecule pharmacodynamic substance chlorogenic acid were the indicators, and the stop time and membrane type in ultrafiltration process were optimized. The temperature, pressure, and feed rate were investigated to determine the influence degree of each factor on the permeability and retention rate, and then the optimum process parameters of the ultrafiltration membrane process were optimized by using Box-Behnken design-response surface method. Results: The sequence of common polymer retention rate from high to low is: the influencing factor A (temperature), B (pressure), C (feed rate), and there was a negative correlation with the temperature. For the chlorogenic acid transmission rate, the influencing factor A (temperature) was larger than B (pressure), and C (feed rate) was lowest. There was a “∩” relationship between chlorogenic acid permeability and pressure at a certain temperature and rate. The results of optimized process were as follows: liquid temperature was 35 ℃, feed rate was 262 mL/min, and membrane pressure was 15.0 psi (1 psi = 6.895 kPa). The chlorogenic acid transmission rate was (91.470 ± 0.988)%, and polymer retention rate was (80.080 ± 2.296)%. The comprehensive score was (85.780 ± 1.641)% and RSD was 0.46%. There was a small difference between the two processes. Conclusion: Hollow fiber membrane, which is a sustainable and green resource utilization, has a good permeability for small bioactive compounds in wastewater, and has excellent retaining effect on common macromolecules. © 2019, Editorial Office of Chinese Traditional and Herbal Drugs.

Optimization of ex vivo inducible nitric oxide synthase gene transfer to vein grafts.

BACKGROUND: Vein graft failure as the result of intimal hyperplasia (IH) remains a significant clinical problem. Ex vivo modification of vein grafts using gene therapy is an attractive approach to attenuate IH. Gene transfer of the inducible nitric oxide synthase (iNOS) gene effectively reduces IH. However, iNOS activity after gene transfer may be impaired by the availability of cofactor, such as tetrahydrobiopterin (BH4). The purpose of this study is to determine the optimal conditions for ex vivo adenoviral-mediated iNOS gene transfer into arterial and venous vessels. METHODS: Porcine internal jugular veins and carotid arteries were infected ex vivo with the adenoviral iNOS vector (AdiNOS) and with an adenovirus carrying the cDNA encoding guanosine triphosphate cyclohydrolase I (AdGTPCH), the rate-limiting enzyme for BH4 synthesis. The production of nitrite, cyclic guanosine monophosphate (cGMP), and biopterin were assessed daily. RESULTS: Nitric oxide (NO) production after iNOS gene transfer was maximal when vessels were cotransduced with AdGTPCH. NO production in these vessels persisted for more than 10 days. Vein segments generated approximately 2-fold more nitrite, cGMP, and biopterin than arterial segments infected with AdiNOS/AdGTPCH. Submerging vein segments into adenoviral solution resulted in improved gene transfer with greater nitrite and cGMP release compared with infections carried out under pressure intraluminally. Similarly, injury to the vein segments before infection with AdiNOS resulted in less nitrite production. CONCLUSIONS: These data demonstrate that AdiNOS can efficiently transduce vein segments ex vivo and that the cotransfer of GTPCH can optimize iNOS enzymatic activity. This cotransfer technique may be used to engineer vein grafts before coronary artery bypass to prevent IH.     

How to explore the effects of sex hormone on blood vessels

<正>The risk of cardiovascular disease increases along with aging. There are increasing interests in researches on the protective effects of hormone replacement therapy (HRT) on cardiovascular system in postmenopausal women. In this article we will review how we have explored the evidence of different sex hormones on blood vessels since 1996. The results showed that low-dose HRT significantly protected cardiovascular system in postmenopausal women. However, the high-dose 17β-estradiol (E2), with or without progesterone (P) or testosterone (T),or any hormone alone, as their concentrations increase, may even inhibit the protective effects of low-dose HRT on blood vessels.

Constituent ratio of motor fibers from the C5-C7 spinal nerves in the radial nerve is greater in pup rats than in adult rats

Clinically, injuries of C5-C7 of the brachial plexus cause falling of the wrist and fingers in infants but not in adults unless 4 consecutive spinal nerves are injured. The purpose of this study was to compare the constituent difference of spinal nerves in the radial nerve between pup and adult rats.A group of 16 pup rats and a group of 16 adult rats were each divided into 2 groups of 8 (P1 and A1 groups, C5-C6 were divided; P2 and A2 groups, C5-C7 were divided]). A nerve conduction study and histological examination were performed to evaluate radial nerve innervation to the extensor digitorum communis muscle after dividing the spinal nerves. Retrograde tracing with 5% cholera toxin B for anterior horn motoneurons of the spinal cord innervating the radial nerve was performed in 8 pup rats and 8 adult rats. Results showed that the division of C5-C7 caused more significant damage to radial nerve innervation to the extensor digitorum communis in pups than in adults, although the division of C5-C6 did not. In pups, the percentages (median with interquartile) of anterior horn motoneurons of the spinal cord innervating the radial nerve were 36.4 (28.3-38.5) in C5-C6, 28.1 (24.5-32.5) in C7, and 37.5 (36.5-39.3) in C8-T1. In adults, they were 24.2 (23.6-27.8) in C5-C6, 21.8 (19.5-26.3) in C7, and 50.7 (48.7-55.5) C8-T1.This study implies that C7 innervation in the radial nerve in humans may be more critical to the function of this nerve in infants than in adults.
