We applied stable carbon isotopes,ultraviolet-visible absorption(UV-Vis),fluorescence excitation-emission matrices spectroscopy(EEMs),and Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR-MS)to investigate the chemical composition and sources of the dissolved organic matter(DOM)in both the water column and pore water in Xiangshan Bay,a representative semi-enclosed and eutrophic bay in Zhejiang Province,*** protein-like fluorescent component(C1)and two humic-like fluorescent components(C2 and C3)were identified by PARAFAC *** concentration of dissolved organic carbon(DOC),the relative intensities of C2,C3,and black carbon-like compounds are all negatively correlated with salinity,indicating that there is a dilution effect of terrestrial signals by seawater in Xiangshan *** differences in light penetration ability of Xiangshan Bay cause different degrees of photo-degradation,which may play an important role in the transformation of organic matter in Xiangshan *** weak correlation between the C1 fluorescent component and salinity indicates that autochthonous sources cannot dominate the protein-like FDOM in the Xiangshan Bay drainage *** sources(such as anthropogenic inputs and release of pore water)also affect the distribution of the protein-like fluorescent component under eutrophication *** relative proportion of the protein-like fluorescent component in Xiangshan Bay is on a medium level in China and anthropogenic inputs may be a significant source of DOM in coastal bays.

Anesthetic injection pain and hematoma occurrence during upper blepharoplasty:Comparison between thin needles and thick needles

Chinese Journal of Plastic and Reconstructive Surgery 2022年第2期4卷 63-66页

Background:Upper blepharoplasty is one of the most commonly performed esthetic surgeries,but injection pain during local anesthesia often disturbs *** objective of this study was to identify the pain levels associated with anesthetizing the upper eyelids in blepharoplasty and determine whether injection with thin needles is associated with less pain and bleeding than injection with thick ***:The study included 50 patients who underwent bilateral upper *** eyelids were anesthetized using 2%lidocaine with 1:100000 *** upper eyelid was randomly injected with a thin needle(26G)and the other with a thick needle(22G).The pain level was scored by patients immediately after the injection of each eyelid using a visual analog scale(VAS)ranging from 0 to *** incidence of eyelid hematomas caused by the anesthetic injection was also ***:The VAS scores in eyelids injected with thin needles were not significantly lower than those in eyelids injected with thick needles(4.0 vs.4.0,P=0.393).The formation of eyelid bruises caused by thin-needle injection was less frequent than that caused by thick-needle injection(16%vs.26%),but there was no significant difference between the two groups(P=0.326).Conclusion:Using thin needles for local anesthesia during upper blepharoplasty could not significantly decrease injection pain or hematoma occurrence compared with that associated with using thick needles.
