Facial Artery Branch Thrombolysis for Nasal Vascular Embolism Induced by Hyaluronic Acid Injection.

Background: Vascular embolism is a severe complication following hyaluronic acid (HA) filler injections, with hyaluronidase injection being the most effective treatment. The nasal region, including the nose and nasolabial fold, is the most common site of vascular embolism after facial HA injections. Currently, there is insufficient clinical evidence regarding the benefits of facial artery thrombolysis.

Recent advance of small-molecule drugs for clinical treatment of multiple myeloma.

Multiple myeloma (MM) is a hematologic neoplasm of plasma cells that is currently deemed incurable. Despite the introduction of novel immunomodulators and proteasome inhibitors, MM remains a challenging disease with high rates of relapse and refractoriness. The management of refractory and relapsed MM patients remains a formidable task, primarily due to the emergence of multiple drug resistance.

Clinically approved small-molecule drugs for the treatment of rheumatoid arthritis.

Rheumatoid arthritis (RA) is a persistent autoimmune ailment that is typified by the development of pannus, proliferation of synovial lining cells, microvascular neogenesis, infiltration of interstitial inflammatory cells, and destruction of cartilage and bone tissue. The disease not only imposes physical pain and economic burden on patients, but also results in a significant decline in their quality of life, rendering it a leading cause of disability. General treatment and drugs are commonly employed to alleviate the condition and symptoms of RA.

Determinants of the intensity of uremic pruritus in patients receiving maintenance hemodialysis: A cross-sectional study.

Background: Uremic pruritus (UP) is a common and frustrating symptom in patients receiving hemodialysis (HD). The majority of patients have mild to moderate itching of the skin, and a small percentage have severe itching, which seriously affects their quality of life and survival rate. However, little is known about factors that influence the intensity of itching in patients.

Comparison of two different sevoflurane expelling methods on emergence agitation in infants following sevoflurane anesthesia.

Purpose: To investigate the effects of two different inhalation anesthetic expelling methods on emergence agitation in infants following sevoflurane anesthesia.

Methods: 100 infants (1~3 years old) with cleft lip and palate and ASA classification I~II were randomized into two groups, a sevoflurane concentration decreasing expelling group (group n = 50 cases) and a low fresh gas flow expelling group (group D = 50 cases). The operation for cleft lip and palate repair was under general anesthesia, in which 30 minutes after initiation of narcosis ending extubation was indicated and after the tubes were removed the patients were sent to the post-anesthesia care unit (PACU) to record anesthesia times, emergence agitation scores, Ramsay scores and adverse reactions including drowsiness, respiratory depression, nausea and vomiting, chills, hiccough or laryngospasms.

[Analysis of hydrogen-production performance in a UASB system at low pH].

This experiment used upflow anaerobic sludge blanket (UASB) with brown sugar water as fermentation substrate and sewage sludge as the initiation sludge of the reaction, which was made into granular sludge by adding activated carbon. Emphasis was placed on assessing the hydrogen production performance of the UASB hydrogen bio-production system in the stable ethanol-type fermentation. Under the conditions that the influent COD was 4000 mg x L(-1), the temperature was (35 +/- 1) degrees C and the hydraulic retention time (HRT) was 8 h, a certain amount of NaHCO3 was added to adjust pH from 3.

[Effects of forest gap size and uprooted microsite on the microclimate in Pinus koraiensis-dominated broad-leaved mixed forest].

Three representative forest gaps with pit-mound microsites formed by uprooted trees were selected within the 2.55 hm2 plot in a Pinus koraiensis-dominated broad-leaved mixed forest in Xiao Xing'an Mountains of Northeast China. The cleared land and closed stand were set up as the controls, and the PAR, air temperature and relative humidity in the centers of different size gaps and in mound top as well as the total radiation and precipitation in the gap centers were measured between July and September, 2011 by using multichannel automatic meteorological stations.

[Effects of forest gap size and light intensity on herbaceous plants in Pinus koraiensis-dominated broadleaved mixed forest].

1 m x 1 m fixed quadrats were parallelly arranged with a space of 2 m in each of six forest gaps in Pinus koraiensis-dominated broadleaved mixed forest, taking the gap center as the starting point and along east-west and south-north directions. In each quadrat, the coverage and abundance of herbaceous plants at different height levels were investigated by estimation method in June and September 2011, and the matrix characteristics within the quadrats were recorded. Canopy analyzer was used to take fish-eye photos in the selected overcast days in each month from June to September, 2011, and the relative light intensity was calculated by using Gap Light Analyzer 2.

[Effects of gap size on the spatial heterogeneity of soil water in Pinus koraiensis-dominated broad-leaved mixed forest].

In August-October 2011, the soil water content (SWC) at different depths in different sized gaps in Pinus koraiensis-dominated broad-leaved mixed forest of Xiaoxing' an Mountains, Northeast China was continuously measured by grid nesting method and time domain reflectometry (TDR), and the spatial heterogeneity of the SWC was analyzed by the principles and approaches of geostatistics. The SWC was most abundant in medium gap, followed by in large gap and in small gap whereas the maximum difference of SWC was the biggest in large gap, followed by in medium gap, and in small gap. The variation range of the nugget of SWC at different depths in the large, medium, and small gaps was 0.

Clinical application of full-face, whole, full-thickness skin grafting: a case report.

A considerable portion of burn patients suffers severe full-face burns. Even after they were treated, some severe abnormalities still stay with them such as upper- and lower-eyelid ectropions, upper- and lower-lip ectropions, microstomia and extensive facial scar hyperplasia accompanied with pruritus. Patients suffer a great deal physically, emotionally and socially.

Spontaneous symmetry breaking and bifurcations in ground-state fidelity for quantum lattice systems.

Spontaneous symmetry breaking occurs in a system when its Hamiltonian possesses a certain symmetry, whereas the ground-state wave functions do not preserve it. This provides such a scenario that a bifurcation, which breaks the symmetry, occurs when some control parameter crosses its critical value. It is unveiled that the ground-state fidelity per lattice site exhibits such a bifurcation for quantum lattice systems undergoing quantum phase transitions.
