Objective:To study the stability and influencing factors of potassium iodate iodized salt that can be sold in Jilin Province.Methods:In November 2020, 10 large supermarkets were randomly selected in Jilin Province, and two kinds of potassium iodate iodized salts were randomly selected in each supermarket, with five copies of each kind, a total of 100 samples of iodized salt, and the iodine content was determined by spectrophotometry (iodide-starch blue light method). Iodized salt samples were classified according to different salt species (mine salt, sea salt and lake salt) and different production processes (refined salt and non-refined salt). The salt was stored at room temperature, and the iodine content in the salt was measured at 0, 10 and 20 days after opening the packaging. The iodine content attenuation rates of different salt species and different production processes were compared.Results:The mine salt, sea salt and lake salt in iodized salt samples were 45, 45 and 10 portions, respectively. The iodine contents of the 0th day of storage [(19.89 ± 1.38), (20.62 ± 1.91), (19.78 ± 1.01) mg/kg] were compared, and the difference was not statistically significant ( F = 2.57, P = 0.093). On the 10th day, the iodine content of mine salt was lower than that of sea salt and lake salt, and the differences were statistically significant ( P < 0.05); on the 20th day, the iodine content of mine salt was lower than that of sea salt, and the difference was statistically significant ( P < 0.05). There was a significant difference in the iodine content of mine salt stored at 0, 10 and 20 days ( F = 90.62, P < 0.001). The iodine content of sea salt and lake salt on the 20th day was significantly lower than that on the 0th and 10th day, and the differences were statistically significant ( P < 0.05). The iodine content attenuation rates of mine salt, sea salt and lake salt on the 0 - 10 days was compared with that on the 10 - 20 days, and the differences were statistically significant ( Z = 2.24, 2.94, 2.80, P < 0.05). There was a significant difference in the iodine content attenuation rates of mine salt, sea salt and lake salt during the 0 - 10 days of storage ( Z = 24.05, P < 0.001), there was no statistically significant difference in the iodine content attenuation rates on 10 - 20 days ( Z = 5.86, P = 0.053). There was no significant difference in iodine content attenuation rates between refined salt and non-refined salt on 0 - 10, 10 - 20 days ( Z = 1.16, 0.28, P > 0.05). There was no statistical significant difference in the iodine content attenuation rates of refined salt and non-refined salt on the 0 - 10 days compared with those of 10 - 20 days ( Z = 0.76, 1.90, P > 0.05). Conclusions:Iodine loss occurs at 20 days after opening the packaging of iodized salt in Jilin Province. The attenuation of iodine content is less affected by salt species and production processes. It is recommended to eat iodized salt within 20 days after opening the packaging.

MicroRNA (miRNA) is a type of highly conserved nucleotide sequence composed of 18 to 25 nucleotides, which can specifically bind to the 3'-noncoding regions of mRNA, and then play a negative regulatory role in degrading mRNA or inhibiting translation. Long non-coding RNA (lncRNA) is a type of nucleotide sequence that exceeds 200 nucleotides in length and cannot encode proteins or can only encode protein peptides. It regulates gene expression at the levels of epigenetic, transcriptional and post-transcriptional. As an important energy storage organ, fat plays an important role in regulating the energy balance of animals, and is closely related to meat production traits such as meat production and meat quality. And the disorder of fat function can lead to hyperlipidemia, type 2 diabetes and a series of cardiovascular diseases, so the molecular regulation mechanism of animal fat deposition has attracted more attention. In recent years, more and more studies have found that miRNA and lncRNA play a crucial role in animal fat deposition. We review here the current research progresses in the role of miRNA and lncRNA in animal fat deposition, to provide theoretical guidance and new ideas for further revealing the molecular regulation mechanism of animal fat deposition.

ObjectiveTo evaluate the effectiveness of Lutongning granules in the treatment of trigeminal neuralgia in animal models and study its mechanism of action， so as to provide laboratory data support for the clinical application of Lutongning granules and precise treatment. MethodMale SD rats were randomly divided into normal group， model group， carbamazepine group （0.06 g·kg^-1·d^-1）， high-dose Lutongning group （2.70 g·kg^-1·d^-1）， and low-dose Lutongning group （1.35 g·kg^-1·d^-1） according to the stratified basic mechanical pain thresholds， with 10 rats in each group. A trigeminal neuralgia model of rats was prepared by injecting 30% talc suspension into the infraorbital foramen area of the rat. The drug groups were administered 10 mL·kg^-1 of drugs by gavage after 2 h of modeling. The normal group and the model group were administered distilled water by gavage under the same conditions once a day for 10 consecutive days. Von Frey brushes were used to determine the mechanical pain threshold of rats. A fully automated blood and body fluid analyzer was employed to detect the blood routine of rats. Hematoxylin and eosin （HE） staining was utilized to detect the pathological changes in the trigeminal ganglion and medulla oblongata tissue. Transmission electron microscopy was used to scan the ultrastructure of the medulla oblongata tissue. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of inflammatory factors interleukin （IL）-1， IL-6， IL-8， tumor necrosis factor （TNF）-α， neuropeptide substance P， and β-endorphins （β-EP） in the serum of rats， and Western blot was used to detect the protein expression levels of IL-1β， purinergic receptor P2X7 （P2X7R）， and phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）. ResultCompared with that in the normal group， the pain threshold of rats in the model group was significantly lower （P<0.01）. The absolute value of neutrophils （NEUT#） and the percentage of neutrophils （NEUT） were significantly improved， and the percentage of lymphocytes （LYMPH） was significantly reduced （P<0.01）. The serum levels of IL-1， IL-6， IL-8， and TNF-α were significantly increased （P<0.01）. SP content in brain tissue was significantly increased， and β-EP content was significantly decreased （P<0.01）. The relative protein expression of IL-1β， P2X7R， and p-p38 MAPK was significantly increased （P<0.05）. HE staining and transmission electron microscopy results of medulla oblongata tissue revealed neuronal degeneration， mild proliferation of microglial cells， reduction in the number of myelinated nerves， and obvious demyelination. The trigeminal nerve fibers of rats were disarranged， and some nerve fibers showed vacuolization. Axons were swollen， and Schwann cells proliferated. Demyelination was observed. Compared with the model group， each administration group significantly increased the pain threshold of rats （P<0.05， P<0.01）， reduced NEUT# and NEUT， and elevated LYMPH （P<0.05， P<0.01）. The administration group significantly decreased the levels of IL-1， IL-6， IL-8， and TNF-α in serum and SP in brain tissue （P<0.01） and increased the level of β-EP （P<0.01）. They significantly down-regulated the protein expression of IL-1β， P2X7R， and p-p38 MAPK（P<0.05， P<0.01） and significantly ameliorated the pathological changes in medulla oblongata tissue and trigeminal nerves of rats. ConclusionLutongning Granules had significant therapeutic effects on trigeminal neuralgia induced by injection of talc into the infraorbital foramen of model rats， and the mechanism may be related to amelioration of P2X7R-mediated neuroinflammation and inhibition of demyelination of myelinated nerves.

Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.
